    The WFS Financial 1998-C Owner Trust Auto Receivable Backed Securities will
consist of four Classes of notes (respectively, the "Class A-1 Notes", the
"Class A-2 Notes", the "Class A-3 Notes" and the "Class A-4 Notes" and
collectively, the "Notes") and one Class of certificates (the "Certificates"
and, together with the Notes, the "Securities"). Principal, in the amounts set
forth herein, and interest at the Interest Rates and Pass-Through Rate specified
above for each Class of Notes and the Certificates will be distributed to the
related Securityholders on February 20, May 20, August 20 and November 20 of
each year (or, if any such day is not a Business Day, on the immediately
succeeding Business Day), beginning February 20, 1999. Distributions on the
Certificates will be subordinated to payments due on the Notes to the extent
described herein. Each Class of Notes and the Certificates will be payable in
full on the Final Distribution Dates specified herein for such Securities. The
payment priority of the Securities shall be in the order the Securities are
listed above.
    
 
    The WFS Financial 1998-C Owner Trust (the "Trust") will be formed pursuant
to a Trust Agreement to be entered into among WFS Financial Auto Loans, Inc.
(the "Seller"), Financial Security Assurance Inc. ("Financial Security"), WFS
Investments, Inc. and Chase Manhattan Bank Delaware, as Owner Trustee. The
Seller is a wholly owned, limited purpose operating subsidiary of WFS Financial
Inc ("WFS"). The Certificates will be issued pursuant to the Trust Agreement and
will represent fractional undivided interests in the Trust. The Notes will be
issued and secured pursuant to an Indenture to be entered into among the Trust,
Financial Security and Bankers Trust Company, as Indenture Trustee, and will
represent obligations of the Trust. Financial Security will issue a financial
guaranty insurance policy for the exclusive benefit of the Notes (the "Note
Policy") and a financial guaranty insurance policy for the exclusive benefit of
the Certificates (the "Certificate Policy" and, together with the Note Policy,
the "Policies").
 
   
    The material property of the Trust will include (i) a pool of retail
installment sales contracts and a limited number of installment loans (the
"Contracts") secured in both instances by new or used automobiles and light duty
trucks (the "Financed Vehicles"), (ii) the Policies and (iii) the funds in a
segregated trust account in the name of the Indenture Trustee (the "Spread
Account"). The Contracts were primarily originated by motor vehicle dealers and
purchased by WFS. At least 70.00% of the Contracts, based upon the Cut-Off Date
Aggregate Scheduled Balance, will have been originally underwritten as prime
Contracts and the remainder of the Contracts will have been originally
underwritten as non-prime Contracts. WFS will act as Master Servicer of the
Contracts. The Notes will be secured by the assets of the Trust pursuant to the
Indenture.
    
 
    It is a condition of issuance that the Class A-1 Notes be rated A-1+ by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P") and P-1
by Moody's Investors Service, Inc. ("Moody's" and, together with S&P, the
"Rating Agencies"), and the Class A-2 Notes, Class A-3 Notes, Class A-4 Notes
and the Certificates each be rated AAA by S&P and Aaa by Moody's. The ratings by
S&P of the Notes will be issued without regard to the benefit afforded by the
Note Policy. The rating by Moody's of the Class A-1 Notes will be substantially
based upon the issuance of the Note Policy by Financial Security, and the rating
by Moody's of the Class A-2 Notes, the Class A-3 Notes and the Class A-4 Notes
will be based on the issuance of the Note Policy by Financial Security. The
ratings by each Rating Agency of the Certificates will be based on the issuance
of the Certificate Policy by Financial Security.
 
    Each Class of Notes and the Certificates will be represented by one or more
certificates registered in the name of Cede & Co., as nominee of The Depository
Trust Company ("DTC"). The interests of beneficial owners of the Securities will
be represented by book entries on the records of participating members of DTC.
Definitive Securities will be available only under the limited circumstances
described herein.
 
    THE FINANCIAL GUARANTY INSURANCE POLICIES ARE NOT COVERED BY THE PROPERTY/
CASUALTY INSURANCE SECURITY FUND SPECIFIED IN ARTICLE 76 OF THE NEW YORK
INSURANCE LAW.
Securityholders will not have recourse against that fund. See "The
Policies -- Other Terms of the Policies".
 
     SEE "RISK FACTORS" COMMENCING ON PAGE 11 FOR A DISCUSSION OF THE MATERIAL
RISK FACTORS RELEVANT TO AN INVESTMENT IN THE SECURITIES.
  THE NOTES WILL REPRESENT OBLIGATIONS OF, AND THE CERTIFICATES WILL REPRESENT
  BENEFICIAL INTERESTS IN, THE TRUST AND WILL NOT REPRESENT OBLIGATIONS OF OR
    INTERESTS IN WFS FINANCIAL AUTO LOANS, INC., WESTERN FINANCIAL BANK, WFS
    FINANCIAL INC OR ANY OF THEIR RESPECTIVE AFFILIATES, THE FEDERAL DEPOSIT
            INSURANCE CORPORATION OR ANY OTHER GOVERNMENTAL ENTITY.
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.

                             first to reduce the principal amount of the Class
                             A-1 Notes; second, after the principal amount of

                             full prior to its Note Final Distribution Date, the

                             Final Distribution Date will include an amount
                             sufficient to reduce the unpaid principal amount of

                             accrued interest thereon at the related Interest
                             Rate. See "The Notes -- Optional Redemption."
 
E. Mandatory Redemption....  The Notes may be accelerated if an Event of Default
                             has occurred and is continuing under the Indenture
                             so long as no Insurer Default has occurred and is
                             continuing. If an Insurer Default has occurred and
                             is continuing and an Event of Default has occurred
                             and is continuing, the Trustee may, or if so
                             requested in writing by Holders of Notes represent-

                             Default shall have occurred and be continuing,
                             under certain circumstances Financial Security will
                             have the right (in addition to its obligation to
                             make Scheduled Payments on the Notes in accordance
                             with the terms of the Note Policy), but not the
                             obligation, to elect to accelerate the principal of
                             the Notes and to cause the Master Servicer or the
                             Trustee to sell or otherwise liquidate the property
                             of the Trust and to deliver the proceeds to the
                             Indenture Trustee for distribution in accordance
                             with the terms of the Indenture. See "The
                             Notes -- Events of Default."
 
Terms of the
Certificates...............  The principal terms of the Certificates will be as
                             described below:
 
   
A. Interest................  On each Distribution Date, the Owner Trustee or any
                             paying agent as the Owner Trustee may designate
                             from time to time (the "Paying Agent") will
                             distribute pro rata to Certificateholders of record
                             as of the related Record Date accrued interest at
                             the rate of     % per annum (the "Pass-Through
                             Rate") on the Certificate Balance, as defined
                             below, as of the immediately preceding Distribution
                             Date (after giving effect to distributions of
                             principal to be made on such immediately preceding
                             Distribution Date) or, in the case of the first
                             Distribution Date, on the Original Certificate
                             Balance. Interest in respect of a Distribution Date
                             will accrue from and including the Cut-Off Date (in
                             the case of the first Distribution Date), or from
                             and including the most recent Distribution Date on
                             which interest has been paid, to but excluding the
                             current Distribution Date. Interest on the
                             Certificates for any Distribution Date due but not
                             paid on such Distribution Date will be due on the
                             next Distribution Date, together with, to the
                             extent permitted by applicable law, interest on
                             such shortfall at the Pass-Through Rate. See "The
                             Certificates -- Distributions of Interest" and
                             "Certain Information Regarding the Securities --
                             Distributions on the Securities."
    
 
   
                             The "Certificate Balance" will equal $77,000,000
                             (the "Original Certificate Balance") on the Closing
                             Date and on any date thereafter will equal the
                             Original Certificate Balance reduced by all
                             distributions of principal previously made in
                             respect of the Certificates. Distributions on the
                             Certificates will be subordinated to payments of
                             interest and principal on the Notes as described
                             under "The Certificates" and "Certain Information
                             Regarding the Securities -- Distributions on the
                             Securities."
    
 
B. Principal...............  No principal will be paid on the Certificates until
                             the Distribution Date on which the principal amount
                             of the Class A-1, Class A-2, Class A-3 and Class
                             A-4 Notes has been reduced to zero. On such
                             Distribution Date and each Distribution Date
                             thereafter, principal of the Certificates will be
                             payable in an amount equal to the Certificate
                             Principal Distributable Amount for such
                             Distribution Date, calculated as described under
                             "Certain Information Regarding the
                             Securities -- Distributions on the
                             Securities -- Deposits to the Distribution
                             Accounts; Priority of Payments." If not paid in
                             full prior to the Certificate Final Distribution
                             Date, the remaining Certificate Balance, if any,
                             will be payable on that date. See "The
                             Certificates -- Distributions of Principal."
 
C. Optional Prepayment.....  In the event of an Optional Purchase, the
                             Certificates will be repaid in whole, but not in
                             part, at a repayment price equal to the Certificate

                             Balance plus accrued interest thereon at the
                             Pass-Through Rate. See "The
                             Certificates -- Optional Prepayment."
 
Security for the
Securities.................  The principal security for the Securities will be
                             as described below:
 
   
A. The Contracts...........  The Contracts will consist of retail installment
                             sales contracts and installment loans, secured by
                             liens on the Financed Vehicles, purchased from WFS
                             by the Seller and from the Seller by the Trust,
                             including the right to receive the payments
                             thereunder on and after the Cut-Off Date. The
                             Seller will be required to repurchase Contracts if
                             (a) (i) any defect in the documentation as to a
                             Contract exists or the documentation has not been
                             received by the Owner Trustee, (ii) the Contract
                             has not been executed by its Obligor or (iii) any
                             representation or warranty of the Seller was
                             incorrect when made and that defect, omission or
                             incorrectness is not cured within 90 days and (b)
                             that defect, omission or incorrectness materially
                             and adversely affects the Securityholders, the
                             Indenture Trustee, the Owner Trustee or Financial
                             Security. The Contracts were purchased from new and
                             used car dealers or originated directly from
                             consumers by WFS. The Contracts were originated in
                             California and 40 other states by new and used car
                             dealers not affiliated with WFS, except for a
                             limited number of Contracts originated directly
                             from consumers by WFS. The Contracts will be
                             selected by WFS from its portfolio of retail
                             installment sales contracts and installment loans
                             based upon the criteria to be specified in the Sale
                             and Servicing Agreement. As of the Cut-Off Date,
                             the Aggregate Scheduled Balance will be
                             $700,000,000 (the "Cut-Off Date Aggregate Scheduled
                             Balance") and the Contracts will have an expected
                             weighted average annual percentage rate of
                             approximately 14.68% and an expected weighted
                             average remaining maturity of approximately 58
                             months. See "The Contracts Pool."
    
 
   
                             Approximately 26.36% of the aggregate principal
                             amount of the Contracts will be "Rule of 78's
                             Contracts" and approximately 73.64% will be "Simple
                             Interest Contracts," based upon the anticipated
                             Scheduled Balances of the Contracts as of the
                             Cut-Off Date. See "Index of Definitions" for the
                             definition of "Rule of 78's Contract" and "Simple
                             Interest Contract."
    
 
                             All net collections received by the Master Servicer
                             on or in respect of the Contracts and any Advances
                             made by the Master Servicer will be deposited in or
                             credited to the Collection Account or, in certain
                             limited instances, the Holding Account. All amounts
                             paid under the Policies will be solely deposited in
                             or credited to the Collection Account. On each
                             Distribution Date, the Indenture Trustee will
                             distribute the amounts on deposit in the Collection
                             Account with respect to such Distribution Date to
                             the Note Distribution Account and, to the extent
                             applicable, the Certificate Distribution Account.
                             All payments to Noteholders will be made from the
                             Note Distribution Account and to Certificateholders
                             from the Certificate Distribution Account. See
                             "Certain Information Regarding the
                             Securities -- The Accounts and Eligible
                             Investments" and "-- Distributions on the
                             Securities."
 
B. The Spread Account......  The Securityholders will be afforded limited
                             protection against losses in respect of the
                             Contracts by the establishment of a segregated
                             trust account in the name of the Indenture Trustee
                             for the benefit of the Securityholders (the "Spread
                             Account"). The Spread Account will be
                                        7
<PAGE>   9
 
                             part of the Trust. On each Distribution Date, funds
                             will be withdrawn from the Spread Account for
                             distribution to Securityholders to cover any
                             shortfalls in interest and principal required to be
                             paid on the Securities, to the extent of the funds
                             therein, before giving effect to any claim under
                             the Policies.
 
   
                             The Spread Account will be created with an initial
                             deposit by the Seller of $21,000,000 (the "Spread
                             Account Initial Deposit"). The funds in the Spread
                             Account will thereafter be supplemented on each
                             Distribution Date by the deposit of any Excess
                             Amounts (as defined below), until the cash on
                             deposit in the Spread Account is at least equal to
                             the Specified Spread Account Balance. "Excess
                             Amounts" in respect of a Distribution Date will be
                             calculated as described under "Certain Information
                             Regarding the Securities -- Distributions on the
                             Securities -- Deposits to the Distribution
                             Accounts; Priority of Payments" and will equal the
                             funds on deposit in the Collection Account in
                             respect of such Distribution Date, after giving
                             effect to all distributions required to be made on
                             such Distribution Date. The Specified Spread
                             Account Balance will be either 7% or 10% of the
                             Aggregate Scheduled Balance of the Contracts, based
                             upon fluctuations in the Charge-Off Percentage and
                             the Delinquency Percentage of the Contracts. The
                             Specified Spread Account Balance will not exceed
                             $70,000,000 or be reduced below $12,600,000;
                             provided, however, it shall not be greater than the
                             outstanding principal amount of the Securities if
                             that amount is less than $12,600,000. See "Certain
                             Information Regarding the Securities -- Payment
                             Priorities of the Notes and the Certificates; The

                             If on the last day of any month (each, a
                             "Calculation Day") or on any Distribution Date the
                             amount on deposit in the Spread Account is greater
                             than the Specified Spread Account Balance, any
                             excess cash on deposit therein will be released
                             therefrom and upon such distribution
                             Securityholders will have no further rights in, or
                             claims to, such amounts. See "Certain Information
                             Regarding the Securities -- Withdrawals from the

C. The Policies............  On the Closing Date, Financial Security will issue
                             the Note Policy to the Indenture Trustee and the
                             Certificate Policy to the Owner Trustee pursuant to
                             the insurance, indemnity and pledge agreement to be
                             dated as of November 1, 1998 (the "Insurance
                             Agreement"), among Financial Security, the Trust,
                             the Seller, Bankers Trust Company as Collateral
                             Agent for Financial Security, WII and WFS. Pursuant
                             to the Note Policy, Financial Security will fully,
                             unconditionally and irrevocably guarantee to the
                             Noteholders payment of the Scheduled Payments for
                             each Distribution Date. Pursuant to the Certificate
                             Policy, Financial Security will unconditionally and
                             irrevocably guarantee to the Certificateholders
                             payment of the Guaranteed Distributions for each
                             Distribution Date. See "The Policies" and
                             "Financial Security Assurance Inc."
    
 
Optional Purchase..........  The Seller may, but will not be obligated to,
                             purchase all of the Contracts in the Trust, and
                             thereby cause early retirement of all outstanding
                             Securities, on any Distribution Date as of which
                             the Aggregate Scheduled Balance is 5% or less of
                             the Cut-Off Date Aggregate Scheduled Balance (an
                             "Optional Purchase"). See "Certain Information
                             Regarding the Securities -- Termination."

The Master Servicer........  WFS, as Master Servicer, will be obligated pursuant
                             to the Sale and Servicing Agreement, subject to the
                             limitations set forth therein, to service the
                             Contracts and to repurchase Contracts if any
                             representations and warranties made by WFS are
                             incorrect or if (i) WFS, as Master Servicer,
                             breaches its obligations under the Sale and
                             Servicing Agreement regarding collection of
                             payments on the Contracts or the maintenance of a
                             first priority perfected security interest in each
                             Contract, (ii) such incorrectness or breach is not
                             cured within 30 days and (iii) that incorrectness
                             or breach materially and adversely affects such
                             Contracts. See "The Master Servicer."
 
Ratings....................  It is a condition of issuance that the Class A-1
                             Notes be rated A-1+ by Standard & Poor's, a
                             division of The McGraw-Hill Companies, Inc. ("S&P")
                             and P-1 by Moody's Investors Service, Inc.
                             ("Moody's" and, together with S&P, the "Rating
                             Agencies"), and the Class A-2, Class A-3 and Class
                             A-4 Notes and the Certificates each be rated AAA by
                             S&P and Aaa by Moody's. The ratings to be received
                             from a Rating Agency will be an assessment by that
                             Rating Agency of the likelihood of full repayment
                             of principal and interest on the related Securities
                             by the Final Payment Date and does not reflect an
                             assessment of whether or to what extent the related
                             Securities will be subject to prepayment. In
                             addition, a rating is not a recommendation to buy,
                             sell or hold the Securities and any rating assigned
                             may be revised or withdrawn by the assigning Rating
                             Agency. See "Risk Factors -- Ratings of the
                             Securities."
 
Tax Status.................  In the opinion of Mitchell Silberberg & Knupp LLP,
                             special tax counsel to the Seller, for both federal
                             and California income tax purposes, the Notes will
                             be characterized as debt, and the Trust will not be
                             characterized as an association (or a publicly
                             traded partnership) taxable as a corporation. Each
                             Noteholder, by the acceptance of a Note, will agree
                             to treat the Notes as indebtedness, and each
                             Certificateholder, by the acceptance of a
                             Certificate, will agree to treat the Trust as a
                             partnership in which the Certificateholders are
                             partners for federal income tax purposes. See
                             "Certain Federal Income Tax Consequences" and
                             "Certain California Income Tax Consequences."
 
ERISA Considerations.......  Subject to the considerations discussed under
                             "ERISA Considerations," the Notes will be eligible
                             for purchase by employee benefit plans that are
                             subject to the Employee Retirement Income Security
                             Act of 1974, as amended ("ERISA").
 
                             Since the Certificates will be subordinated to the
                             Notes to the extent described herein, employee
                             benefit plans subject to ERISA will not be eligible
                             to purchase the Certificates. Any benefit plan
                             fiduciary considering purchase of the Securities
                             should, among other things, consult with its
                             counsel in determining whether all required
                             conditions have been satisfied. See "ERISA
                             Considerations."
 
Legal Investment...........  The Class A-1 Notes have been structured to be
                             eligible securities for purchase by money market
                             funds under Rule 2a-7 under the Investment Company
                             Act of 1940, as amended. A money market fund should
                             consult its legal advisors regarding the
                             eligibility of the Class A-1 Notes under Rule 2a-7,
                             the fund's investment policies and objectives and
                             an investment in the Class A-1 Notes.
 
Risk Factors...............  The Securities offered hereby are subject to
                             several risk factors. The ratings of the Securities
                             may be changed or withdrawn and do not
 
                                        9
<PAGE>   11
 
   
                             include any assessment as to the prepayment of the
                             Securities. Approximately 50.06% of the Contracts,
                             based upon the Cut-Off Date Aggregate Balance will
                             have been originated in California. Accordingly,
                             adverse economic conditions in California may have
                             a disproportionate effect on the losses on the
                             Contracts. There is no secondary market for the
                             Securities, and none may develop or be maintained,
                             thereby making the Securities illiquid. See "Risk
                             Factors" for a more detailed discussion of such
                             risks.

                                  RISK FACTORS
 
     Prospective investors should consider the following risk factors in
considering the purchase of the Securities.
 
RATINGS OF THE SECURITIES ARE SUBJECT TO REVISION OR WITHDRAWAL
 
     It is a condition of issuance that the Class A-1 Notes be rated A-1+ by S&P
and P-1 by Moody's, and the Class A-2 Notes, Class A-3 Notes, Class A-4 Notes
and the Certificates each be rated AAA by S&P and Aaa by Moody's. The ratings by
S&P of the Notes will be issued without regard to the benefit afforded by the
Note Policy. The rating by Moody's of the Class A-1 Notes will be substantially
based on the issuance of the Note Policy by Financial Security, and the rating
by Moody's of the Class A-2 Notes, the Class A-3 Notes and the Class A-4 Notes
will be based on the issuance of the Note Policy by Financial Security. The
ratings by each Rating Agency of the Certificates will be based on the issuance
of the Certificate Policy by Financial Security. Although the ratings of the
Notes by S&P do not take into account the benefit of the Note Policy, the Notes
will have the benefit of the Note Policy.
 
     There is no assurance that any such rating will continue for any period of
time or that it will not be revised or withdrawn entirely by the assigning
rating agency if, in its judgment, circumstances (including, in the case of the
Certificates and, with respect to Moody's in the case of the Class A-2 Notes,
the Class A-3 Notes and the Class A-4 Notes, as a result of any change in the
claims-paying ability of Financial Security) so warrant. A revision or
withdrawal of such rating may have an adverse effect on the market price of the
Notes and the Certificates. A security rating is not a recommendation to buy,
sell or hold the Securities. The ratings to be received from a Rating Agency
will be an assessment by that Rating Agency of the likelihood of full repayment
of principal and interest on the related Securities by the Fixed Payment Date
and does not reflect an assessment of whether or to what extent the related
Securities will be subject to prepayment.
 
GEOGRAPHIC CONCENTRATION OF CONTRACTS IN CALIFORNIA INCREASES POTENTIAL ADVERSE
EFFECT OF CHANGES IN CALIFORNIA ECONOMY
 
   
     Based upon the Cut-Off Date Aggregate Scheduled Balance of the Contracts,
approximately 50.06% of the Contracts will have been originated in the State of
California, and not more than 5.91% of the Contracts will have been originated
in any other individual state. See "The Contracts Pool." Because of this
geographic concentration, losses on the Contracts may be affected
disproportionately by reason of general economic conditions in California, to
the extent those conditions differ significantly and adversely to those in the
other states in which Contracts have been originated.
    
 
LIMITED LIQUIDITY MAY RESTRICT RESALE OF SECURITIES
 
     There is currently no secondary market for the Securities offered hereby.
The Underwriters currently intend to make a market in the Securities offered
hereby, but neither of them is under any obligation to do so. There can be no
assurance that a secondary market will develop or, if a secondary market does
develop, that it will provide the Securityholders with liquidity of investment
or that any such secondary market will continue for the life of the Securities
offered hereby.
 
                             FORMATION OF THE TRUST
 
GENERAL
 
     The Trust will be a business trust formed under the laws of the State of
Delaware pursuant to the Trust Agreement for the transactions described herein.
After its formation, the Trust will not engage in any activity other than (i)
acquiring, holding and managing the Contracts and the other assets of the Trust
and proceeds therefrom; (ii) issuing the Notes and the Certificates; (iii)
making payments on the Notes and the Certificates; and (iv) engaging in other
activities that are necessary, suitable or convenient to accomplish the
foregoing purposes or are incidental thereto or connected therewith.
 
                                       11
<PAGE>   13
 
     On the Closing Date, the Seller will establish the Trust by selling and
assigning the Contracts to the Trust. WFS will act as Master Servicer of the
Contracts and will receive compensation and fees for such services. See "The
Master Servicer -- Servicing Compensation." WFS, as Master Servicer, may retain
physical possession of the original executed Contracts, and certain other
documents or instruments relating to the Contracts, as custodian for the Owner
Trustee pursuant to the Sale and Servicing Agreement, or may employ one or more
Subservicers as custodians. In order to protect the Trust's ownership interest
in the Contracts, the Trust's interest in the Contracts will be perfected by the
Seller, filing UCC-1 financing statements in the State of California to give
notice of the Trust's ownership of the Contracts. Under the Sale and Servicing
Agreement and the Indenture, WFS will be obligated to take all necessary steps
to preserve and protect the interests of the Trustees in the Contracts. Neither
the Indenture Trustee nor the Owner Trustee will be responsible for the
legality, validity or enforceability of any security interest in respect of any
Contract. WFS will not physically segregate the Contracts from the other retail
installment sales contracts and installment loans owned or serviced by it and
will not stamp the Contracts with notice of the sale to the Seller or the Trust.
See "Certain Legal Aspects of the Contracts."
 
     Simultaneously with the issuance of the Securities, Financial Security will
issue the Note Policy to the Indenture Trustee and the Certificate Policy to the
Owner Trustee for the benefit of the related Securityholders. Under the Note
Policy and the Certificate Policy, Financial Security will unconditionally and
irrevocably guarantee to the related Securityholders full and complete payment
of the Scheduled Payments and the Guaranteed Distributions, respectively, for
each Distribution Date. Financial Security will have a lien on the Contracts and
other documents relating to the Contracts subordinate to the interest of the
Securityholders, which lien cannot be executed upon until all required payments
under the Policies have been made. See "The Policies."
 
   
     On and after the Closing Date, the property of the Trust will consist of
(i) Contracts secured by the Financed Vehicles; (ii) principal and interest due
under the Contracts on and after November 1, 1998 (the "Cut-Off Date"); (iii)
security interests in the Financed Vehicles; (iv) a financial guaranty insurance
policy (the "Note Policy") to be issued by Financial Security for the exclusive
benefit of Noteholders, which will unconditionally and irrevocably guarantee
payment of the Scheduled Payments on each Distribution Date; (v) a financial
guaranty insurance policy (the "Certificate Policy" and, together with the Note
Policy, the "Policies") to be issued by Financial Security for the exclusive
benefit of Certificateholders, which will fully, unconditionally and irrevocably
guarantee payment of the Guaranteed Distributions on each Distribution Date;
(vi) amounts on deposit in the Collection Account, the Note Distribution
Account, the Certificate Distribution Account, the Spread Account and the
Holding Account, including all Eligible Investments therein and all income from
the investment of funds therein and all proceeds therefrom; (vii) proceeds from
claims under certain insurance policies in respect of individual Financed
Vehicles or obligors under the Contracts (the "Obligors"); and (viii) rights as
a third party beneficiary under the sale and servicing agreement to be dated as
of November 1, 1998 (the "Sale and Servicing Agreement"), among the Trust, the
Seller and the Master Servicer. Pursuant to the Indenture, the property of the
Trust (other than the Certificate Distribution Account and the Certificate
Policy) will be held by the Master Servicer for the benefit of the Indenture
Trustee and Financial Security on behalf of the holders of the Notes.
    
 
     After the sale and assignment of the Contracts to the Trust, so long as WFS
acts as Master Servicer, WFS's obligations to the Trust with respect to the
Contracts will be limited to repurchasing Contracts if(a)(i) any representations
and warranties made by WFS are incorrect, (ii) WFS, as Master Servicer, breaches
its obligations under the Sale and Servicing Agreement regarding collection of
payments on the Contracts or (iii) WFS, as Master Servicer fails to maintain a
first priority perfected security interest in each Contract and (b) such
incorrectness or breach is not cured within 30 days and (c) that incorrectness
or breach materially and adversely affects such Contracts. See "The Master
Servicer."
 
     The Trust's principal offices will be in Wilmington, Delaware, in care of
Chase Manhattan Bank Delaware, as Owner Trustee, at the address listed below
under "The Owner Trustee."

CAPITALIZATION
 
     The Trust will initially be capitalized with equity equal to the Original
Certificate Balance. WII will purchase Certificates with an original Certificate
Balance of approximately 1% of the Original Certificate Balance and the
remaining equity interests will be sold to third party investors that are
expected to be unaffiliated with the Seller, the Master Servicer or the Trust.
 
     The following table illustrates the capitalization of the Trust as of the
Cut-Off Date, as if the issuance and sale of the Securities had taken place on
such date:

THE OWNER TRUSTEE
 
     Chase Manhattan Bank Delaware will be the Owner Trustee under the Trust
Agreement. Chase Manhattan Bank Delaware is a Delaware corporation and its
Corporate Trust Office is located at 1201 Market Street, Wilmington, Delaware
19801.
 
     The Owner Trustee will have the rights and duties set forth herein under
"Certain Information Regarding the Securities -- The Trustees" and "-- Duties of
the Trustees."
 
                               THE CONTRACTS POOL
 
   
     Each Contract is a retail installment sales contract originated by a new or
used car dealer located in California or one of the other 40 states listed below
and purchased by WFS (except for a limited number of Contracts, not to exceed 2%
of the Cut-Off Date Aggregate Scheduled Balance, in the form of installment
loans originated by branch offices of WFS directly to consumers). Each Contract
is secured by a Financed Vehicle. Except as otherwise noted, all references to
contracts include installment loans.
    
 
   
     WFS will select the Contracts from its portfolio of fixed-interest rate
retail installment sales contracts which are secured by new and used automobiles
or light-duty trucks. The Contracts were underwritten and purchased by WFS in
the ordinary course of its business operations. It is currently anticipated,
based on the Cut-Off Date Aggregate Scheduled Balance, that not less than
approximately 70.00% of the Contracts will have been originally underwritten as
prime contracts. Approximately 50.06% of the aggregate principal amount of the
Contracts will have been originated in California and approximately 49.94% of
the aggregate principal amount of the Contracts will have been originated in
states other than California. Each of the Contracts is fully amortizing and
provides for level payments over its term, with the portions of principal and
interest of each such level payment being determined on the basis of the Rule of
78's or the simple interest (actual number of days) method. The amortization of
the Rule of 78's Contracts will result in the outstanding principal balance on
each such Contract being in excess of the Scheduled Balance of that Contract.
For purposes of the Trust, all Rule of 78's Contracts are amortized on an
actuarial basis to prevent shortfalls of principal payments on the Securities.
As amortization on an actuarial basis produces a faster amortization than does
application of the Rule of 78's, there will not be a shortfall of principal in
any event, including as a result of prepayments or timely payment to maturity of
a Rule of 78's Contract.
    
 
   
     The aggregate outstanding principal amount of the Contracts will be
$700,000,000. Based on the anticipated Cut-Off Date Aggregate Scheduled Balance,
approximately 26.36% of the Contracts will be Rule of 78's Contracts and
approximately 73.64% will be Simple Interest Contracts.
    
 
   
     The information concerning the Contracts presented in this Prospectus is
based upon a pool of retail installment sales contracts and installment loans
originated through October 31, 1998. While information as of the Cut-Off Date
for the Contracts that will be actually sold to the Trust may differ somewhat
from the Contract information presented herein, not more than 5% of the
Contracts that will be sold to the Trust will have characteristics that vary
from the information concerning the Contracts presented.
    
 
                                       13
<PAGE>   15
 
   
     For Contracts originated through October 31, 1998, approximately 21.53% of
the aggregate principal amount of the Contracts relate to the purchase of new
vehicles and approximately 78.47% of the Contracts relate to the purchase of
used vehicles. Approximately 55.16% of the aggregate principal amount of these
Contracts consists of contracts secured by automobiles and approximately 44.84%
of the aggregate principal amount consists of contracts secured by light-duty
trucks. These Contracts have an annual percentage rate ("APR") of at least 6.90%
and not more than 30.0%, and the weighted average APR of these Contracts is
approximately 14.68%. These Contracts have remaining maturities of at least 4
months but not more than 84 months and original maturities of at least 12 months
but not more than 84 months. The weighted average original maturity of these
Contracts was 60 months and the weighted average remaining maturity of these
Contracts as of October 31, 1998 was 58 months. It is currently anticipated that
not more than 30.05% of the aggregate principal amount of the Contracts (by
Cut-Off Date Aggregate Scheduled Balance) will have had original maturities of
more than 60 months. The average principal amount outstanding per Contract as of
October 31, 1998 was $12,434.06 and the outstanding principal balance of these
Contracts as of October 31, 1998 ranged from $1,001.04 to $62,194.22.

UNDERWRITING PROCEDURES RELATING TO THE CONTRACTS
 
     WFS and its predecessors and affiliates have underwritten and purchased
motor vehicle installment sales contracts and installment loans (collectively,
"contracts") since 1973. The discussion herein regarding contracts is applicable
to the Contracts and none of the Contracts included in the Contracts Pool will
have been underwritten under special financing programs. WFS purchases contracts
across the full spectrum of the prime and non-prime credit quality market. It
offers competitive rates commensurate with the risks inherent in its obligors'
ability to make payments under their contracts.
 
                                       15
<PAGE>   17
 
     Substantially all contracts are nonrecourse to the originating dealer. In
the case of new vehicle contracts, the original amount financed does not exceed
the sum of the dealer's cost, taxes, license fees, service warranty cost and, if
applicable, premium for credit life or credit disability insurance, and in some
cases, miscellaneous costs. Over-advances (i.e., advances in excess of the
amount specified in the previous sentence) may be made under certain
circumstances to assist a dealer in selling an automobile or light duty truck by
permitting a lower down payment, and in some cases no down payment, based on the
creditworthiness of the applicant. For used vehicles, the amount financed does
not exceed the wholesale "blue book" value for the vehicle plus the related
expenses and the over-advances just described. WFS does not have a fixed maximum
amount financed as a percentage of the wholesale or retail value of the financed
vehicle. Any amount financed in excess of the wholesale value of the financed
vehicle is dependent upon the creditworthiness of the applicant. WFS believes
that, with respect to substantially all contracts, the total amount financed,
including any over-advance, does not exceed the retail value of the financed
vehicle.
 
     Each contract is fully amortizing and provides for level payments over its
term with the portion of principal and interest of each level payment determined
generally on the basis of the sum of the digits (also known as the Rule of
78's), or on a simple interest basis otherwise. WFS does not have minimum
maturity requirements; however, contracts of less than three years maturity are
seldom purchased or made due to low customer demand.
 
     WFS relies primarily on the judgment of its trained credit analysts who
evaluate the applicant's credit and stability, including income, employment and
housing, within the context of WFS' underwriting guidelines. WFS' credit
analysts are closely monitored by management and internal quality control
professionals to insure adherence to WFS' underwriting guidelines. The goal in
underwriting contracts is to correctly determine whether an applicant has the
ability and intention to perform on his or her obligations under the contract.
 
     The formal underwriting process for either prime or non-prime contracts
begins when an application is received. Applications are faxed to one of two
processing centers where the system will collect credit data on applicants and
other information used in the underwriting process. The front-end application
processing system will arrange that information for review and analysis by
either a prime or non-prime credit analyst to whom the information will be
automatically queued.
 
     Due to the credit history of some applicants, the credit analyst may
request that the data verification department verify information or seek
clarification of information learned during the review of the applicant's credit
history. Often, items in a credit history which may seem significant to another
financing source will not, upon investigation, preclude the applicant from
possessing the requisite ability and intent to perform on his or her
obligations. The application, credit history, and other relevant information are
then reviewed by the credit analyst for approval or denial. If the contract
amount or terms exceeds the credit analysts's approval authority, a senior
official with the requisite credit approval authority then reviews the
application. In order to maintain its competitive position in the marketplace,
WFS emphasizes a fast approval process and, under normal circumstances, an
approval or declination is given on the same day that the application is
received. When an application is approved, the submitting Dealer is notified.
Upon the Dealer's acceptance of WFS' approval, the contract is purchased.
 
     Approximately one-third of all contracts purchased are reviewed by a senior
credit analyst, the quality control department of WFS or the reunderwriting
department of WFS to insure adherence to established lending guidelines and
compliance with proper documentation requirements.

                   DELINQUENCY AND CONTRACT LOSS INFORMATION
 
   
     The following tables set forth (i) the delinquency experience in regard to
contracts originated and serviced by WFS and its affiliates, including contracts
subsequently sold to WFS Financial Auto Loans, Inc. and WFS Financial Auto Loans
2, Inc. as of and for the years ended December 31, 1993 through 1997 and for the
nine months ended September 30, 1998 and (ii) the loss experience for such
contracts originated and serviced by WFS and its affiliates, including contracts
subsequently sold to WFS Financial Auto Loans, Inc. and WFS Financial Auto Loans
2, Inc. as of and for the years ended December 31, 1993 through 1997 and for the
nine months ended September 30, 1998. There is no assurance that the future
delinquency and loss experience of the Contracts will be similar to that set
forth below. WFS defines delinquency as being past due based on the contractual
due date of the underlying contract.

(1) Includes loss information for contracts that are owned by WFS and contracts
    that were sold to a grantor or owner trust but which are serviced by WFS. It
    is the policy of WFS to charge-off all contracts when they become 120 days
    delinquent, whether such contract is owned by WFS or serviced by WFS for
    others. WFS believes that its charge-off policy is consistent with that
    customarily used in the automobile finance industry.
 
   
     Net charge-offs as a percentage of contracts outstanding for contracts
originated and serviced by WFS increased in 1997 to 3.02%, a 31.3% increase over
the 2.30% experienced in 1996 following a 42.9% increase over the 1.61% net
charge-off level experienced in 1995. Delinquencies increased during the same
periods as a percentage of contracts outstanding from 1.24% at year end 1995 to
1.80% and 2.20% at year end 1996 and 1997, respectively, an increase of 45.16%
and 22.22%, respectively. Net chargeoffs and delinquencies increased from year
end 1997 to September 30, 1998 to 3.34% and 3.67%, respectively, increases of
10.60% and 66.82%, respectively. Loss and delinquency for contracts originated
and serviced by WFS was impacted by a variety of factors including an increase
in the percentage of the outstanding contracts which were originally
underwritten as non-prime contracts, an increase in the number of personal
bankruptcy filings and general economic conditions. Loss and delinquency
experience in the third quarter of 1998 were also impacted by a disruption of
collection efforts arising from WFS' restructuring of its offices. As the
characteristics of the Contracts may be different than that of the entire
portfolio of contracts originated and serviced by WFS, no assurances can be
given that the performance of the Contracts will be similar.

                      POOL FACTORS AND TRADING INFORMATION
 
     The "Note Pool Factor" for each Class of Notes will be a six-digit decimal
which the Master Servicer will compute prior to each Distribution Date with
respect to the Notes indicating the unpaid principal amount of such Class of
Notes, after giving effect to payments to be made on such Distribution Date, as
a fraction of the initial outstanding principal amount of such Class of Notes.
The "Certificate Pool Factor" for the Certificates will be a six-digit decimal
which the Master Servicer will compute prior to each Distribution Date
indicating the remaining Certificate Balance, after giving effect to
distributions to be made on such Distribution Date, as a fraction of the
Original Certificate Balance. Each Note Pool Factor and the Certificate Pool
Factor will be 1.000000 as of the Closing Date, and thereafter will decline to
reflect reductions in the outstanding principal amount of the applicable Class
of Notes, or the reduction of the Certificate Balance, as the case may be. A
Noteholder's portion of the aggregate outstanding principal amount of the
related Class of Notes will be the product of (i) the original denomination of
such Noteholder's Note and (ii) the applicable Note Pool Factor at the time of
determination. A Certificateholder's portion of the aggregate outstanding
Certificate Balance will be the product of (i) the original denomination of such
Certificateholder's Certificate and (ii) the Certificate Pool Factor at the time
of determination.
 
     The Noteholders will receive reports on or about each Distribution Date
concerning payments received on the Contracts, the Pool Balance, each Note Pool
Factor and various other items of information, and the Certificateholders will
receive reports on or about each Distribution Date concerning payments received
on the Contracts, the Pool Balance, the Certificate Pool Factor and various
other items of information. In addition, Securityholders of record during any
calendar year will be furnished information for tax reporting purposes not later
than the latest date permitted by law. See "Certain Information Regarding the
Securities -- Statements to Securityholders."
 
                                USE OF PROCEEDS
 
     The net proceeds from the sale of the Securities (i.e., the proceeds of the
public offering of the Securities minus expenses relating thereto) will be
applied by the Seller to the purchase of the Contracts from WFS.
 
                                   THE NOTES
GENERAL
 
     The Notes will be issued pursuant to the Indenture, a form of which has
been filed as an exhibit to the Registration Statement. Copies of the Indenture
(without exhibits) may be obtained by Noteholders upon request in writing to the
Indenture Trustee at its Corporate Trust Office. Citations to the relevant
Sections of the Indenture appear below and under "Certain Information Regarding
the Securities" in parentheses. The following summary does not purport to be
complete and is subject to the provisions of the Notes and the Indenture;
provided, however, the following summary, together with the information
contained herein under the caption "Certain Information Regarding the
Securities," describes the material terms of the Indenture and the Notes. Where
particular provisions or terms used in the Notes or the Indenture are referred
to, the actual provisions of such documents (including definitions of terms and
Section references) are incorporated by reference as part of such summaries.
 
PAYMENTS OF INTEREST
 
     Interest on the outstanding principal amount of each Class of Notes will
accrue at the applicable Interest Rate and will be payable to the Noteholders of
such Class on each Distribution Date. Interest on the Class A-1 and Class A-2
Notes will be calculated on the basis of the actual days elapsed in an Interest
Period and a 360-day year. Interest on the Class A-3 and Class A-4 Notes will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.
Interest accrued but not paid on any Distribution Date will be due on the
immediately succeeding Distribution Date, together with, to the extent permitted
by applicable law, interest on such shortfall at the related Interest Rate.
Interest payments on the Notes will be made from Net Collections after all
accrued and unpaid Trustees' fees and other administrative fees of the Trust and
payment of all applicable servicing compensation to the Master Servicer
(collectively, "Trust Fees and Expenses")
 
                                       18
<PAGE>   20
 
have been paid. See "Certain Information Regarding the
Securities -- Distributions on the Securities -- Deposits to the Distribution
Accounts; Priority of Payments."
 
PAYMENTS OF PRINCIPAL
 
     Principal payments will be made to the Noteholders, to the extent described
below, on each Distribution Date in an amount equal to the Note Percentage of
the related Principal Distributable Amount, in each case calculated as described
under "Certain Information Regarding the Securities -- Distributions on the
Securities -- Deposits to the Distribution Accounts; Priority of Payments."
Principal payments on the Notes will be made from Net Collections after all
Trust Fees and Expenses have been paid, and after the Note Interest
Distributable Amount has been distributed. See "Certain Information Regarding
the Securities -- Distributions on the Securities -- Deposits to the
Distribution Accounts; Priority of Payments."
 
     Principal payments on the Notes will be applied on each Distribution Date
from the Note Distribution Account as follows: first to the holders of the Class
A-1 Notes until the principal amount of the Class A-1 Notes has been reduced to
zero and in no event later than the Class A-1 Final Distribution Date, second to
the holders of the Class A-2 Notes until the principal amount of the Class A-2
Notes has been reduced to zero, third to the holders of the Class A-3 Notes
until the principal amount of the Class A-3 Notes has been reduced to zero, and
fourth to the holders of the Class A-4 Notes until the principal amount of the
Class A-4 Notes has been reduced to zero. No amount of principal will be paid on
the Certificates until the principal amount of each Class of Notes has been
reduced to zero. See "Certain Information Regarding the Securities -- Deposits
to the Distribution Accounts; Priority of Payments."
 
     The principal amount of each Class of Notes, to the extent not previously
paid, will be due on the related Note Final Distribution Date for that Class of
Notes.
 
     The actual date on which the outstanding principal amount of any Class of
Notes is paid may be earlier than its Note Final Distribution Date based on a
variety of factors, including the factors described under "Certain Information
Regarding the Securities -- Prepayment Considerations."
 
OPTIONAL REDEMPTION
 
     Each Class of outstanding Notes will be subject to redemption in whole, but
not in part, on any Distribution Date relating to an Optional Purchase. The
redemption price will equal the unpaid principal amount of such Class of Notes
plus accrued interest thereon at the applicable Interest Rate.
 
THE INDENTURE TRUSTEE
 
     Bankers Trust Company will be the Indenture Trustee. The Indenture Trustee
is a New York corporation and its Corporate Trust Office is located at Four
Albany Street, New York, New York 10006.
 
     The Indenture Trustee will have the rights and duties set forth under
"Certain Information Regarding the Securities -- The Trustees" and "-- Duties of
the Trustees."
 
EVENTS OF DEFAULT
 
     "Events of Default" under the Indenture will consist of: (i) a default by
the Trust for five days or more in the payment of any interest on the Notes of
any Class when the same becomes due and payable; (ii) a default by the Trust in
the payment of the principal of or any installment of the principal of the Notes
of any Class when the same becomes due and payable; (iii) a default in the
observance or performance of any covenant or agreement of the Trust made in the
Indenture or any representation or warranty made by the Trust in the Indenture
or in any certificate delivered pursuant thereto or in connection therewith
having been incorrect in a material respect as of the time made, and the
continuation of any such default for a period of 30 days after notice thereof is
given to the Issuer by the Indenture Trustee or to the Issuer and the Indenture
Trustee by the holders of Notes evidencing at least 25% of the voting interest
thereof, voting together as a single class; and
 
                                       19
<PAGE>   21
 
(iv) certain events of bankruptcy, insolvency, receivership or liquidation
relating to the Trust (each, a "Trust Insolvency"). (Indenture, Section 5.01)
 
     Upon the occurrence of an Event of Default, so long as an Insurer Default
(as defined below) shall not have occurred and be continuing, Financial Security
will have the right (in addition to its obligation to make Scheduled Payments on
the Notes in accordance with the terms of the Note Policy), but not the
obligation, to elect (i) to accelerate the principal of the Notes and to cause
the Master Servicer or the Trustee to sell or otherwise liquidate the property
of the Trust, in whole or in part on any date or dates following such
acceleration as Financial Security, in its sole discretion, shall elect, and to
deliver the proceeds thereof to the Indenture Trustee for distribution in
accordance with the terms of the Indenture or (ii) to make Scheduled Payments on
the Notes in accordance with the terms of the Note Policy. If an Insurer Default
has occurred and is continuing, upon the occurrence of an Event of Default, the
Trustee may, or if so requested in writing by holders of Notes evidencing at
least 66 2/3% of the voting interests thereof, voting together as a single
class, shall, declare the Notes due and payable at par, together with accrued
interest thereon. Notwithstanding the foregoing, upon the occurrence of a Trust
Insolvency, if an Insurer Default shall have occurred and be continuing, the
Notes will become immediately due and payable at par, together with accrued
interest thereon. (Indenture, Section 5.02) An "Insurer Default" will consist of
(i) a default by Financial Security of its obligations under either Policy or
(ii) certain events of bankruptcy, insolvency, receivership or liquidation
relating to Financial Security.
 
     No sale or liquidation of the property of the Trust described in the
immediately preceding paragraph may be made if the proceeds thereof are not
sufficient to pay all outstanding principal of and accrued interest on the
Notes, unless (i) no Insurer Default has occurred and is continuing and the
related Event of Default arose as described in clauses (i), (ii) or (iv) of the
second preceding paragraph or (ii) an Insurer Default shall have occurred and be
continuing and (a) holders of Notes evidencing 100% of the voting interests
thereof, voting together as a single class, consent to such sale or liquidation,
or (b) (1) the Trustee determines that the property of the Trust will not
continue to provide sufficient funds for the payment of principal of and
interest on the Notes, (2) the Trustee provides prior written notice of such
sale or liquidation to each Rating Agency, and (3) holders of Notes evidencing
66 2/3% of the voting interests thereof, voting together as a single class,
consent to such sale or liquidation. (Indenture, Section 5.04)
 
     Further, in the event that no Insurer Default has occurred and is
continuing, following the occurrence of an Event of Default, if Financial
Security has not elected to accelerate the principal of the Notes and such Event
of Default is subsequently cured, Financial Security shall not thereafter have
the right to elect to accelerate the principal of the Notes or to cause the
property of the Trust to be sold or liquidated by reason of that Event of
Default and the rights of all parties shall thereupon be restored as though such
Event of Default had not occurred.
 
     Following the occurrence of an Event of Default and provided that (i) no
Insurer Default has occurred and is continuing and (ii) Financial Security has
not elected to accelerate the principal of the Notes, the Indenture Trustee and
the Owner Trustee will continue to submit claims under the Policies for any
shortfalls in Scheduled Payments on the Notes and Guaranteed Distributions on
the Certificates, respectively. (Indenture, Section 5.02 and 5.04) See "The
Policies."
 
                                THE CERTIFICATES
 
GENERAL
 
     The Certificates will be issued pursuant to the Trust Agreement, a form of
which has been filed as an exhibit to the Registration Statement of which this
Prospectus is a part. Copies of the Trust Agreement (without exhibits) may be
obtained by holders of Certificates upon request in writing to the Owner Trustee
at its Corporate Trust Office. Citations to the relevant Sections of the Trust
Agreement appear below and under "Certain Information Regarding the Securities"
in parentheses. The following summary describes the material
 
                                       20

terms of the Certificates and the Trust Agreement and does not purport to be
complete and is subject to, and qualified in its entirety by, reference to all
of the provisions of the Certificates and the Trust Agreement. Where particular
provisions or terms used in the Trust Agreement are referred to, the actual
provisions (including definitions of terms and Section references) are
incorporated by reference as part of such summaries.
 
DISTRIBUTIONS OF INTEREST
 
     Interest on the Certificate Balance will accrue at the Pass-Through Rate
and will be payable to Certificateholders on each Distribution Date. Interest
accrued but not paid on any Distribution Date will be due on the immediately
succeeding Distribution Date, together with, to the extent permitted by
applicable law, interest on such amount at the Pass-Through Rate. Interest
distributions with respect to the Certificates will be made from Net Collections
after all Trust Fees and Expenses have been paid and after the Note
Distributable Amount has been distributed. See "Certain Information Regarding
the Securities -- Distributions on the Securities -- Deposits to the
Distribution Accounts; Priority of Payments."
 
DISTRIBUTIONS OF PRINCIPAL
 
     No principal will be paid on the Certificates until the Distribution Date
on which the principal amount of the Class A-1, Class A-2, Class A-3 and Class
A-4 Notes has been reduced to zero. On such Distribution Date and each
Distribution Date thereafter, the Certificateholders will be entitled to
distributions in an amount equal to the Certificate Percentage of the Principal
Distributable Amount, in each case calculated as described under "Certain
Information Regarding the Securities -- Distributions on the
Securities -- Deposits to the Distribution Accounts; Priority of Payments."
Distributions with respect to principal payments will be made from Net
Collections after all Trust Fees and Expenses have been paid and after the Note
Distributable Amount and the Certificate Interest Distributable Amount have been
distributed. See "Certain Information Regarding the Securities -- Distributions
on the Securities -- Deposits to the Distribution Accounts; Priority of
Payments."
 
     If not paid in full prior to the Certificate Final Distribution Date, the
remaining Certificate Balance, if any, will be payable on such Distribution
Date.
 
     The actual date on which the Certificate Balance is reduced to zero may be
earlier than the Certificate Final Distribution Date based on a variety of
factors, including (i) the Seller's right or obligation to repurchase the
Contracts (a) on any Distribution Date as of which the Aggregate Scheduled
Balance is less than 5% of the Cut-Off Date Aggregate Scheduled Balance, or (b)
because of certain material defects in Contract documentation or due to breaches
of its respective representations and warranties in respect thereof, in either
case that materially and adversely affect the interests of Securityholders, the
Indenture Trustee, the Owner Trustee or Financial Security, or (ii) purchases by
the Master Servicer of Contracts due to certain breaches in representations and
warranties made by the Master Servicer or due to certain breaches by the Master
Servicer in servicing procedures, in either case that materially and adversely
affect such Contracts. Any such repurchase or purchase may reduce the average
life of the Contracts. See "Certain Information Regarding the
Securities -- Prepayment Considerations."
 
OPTIONAL PREPAYMENT
 
     The Certificates will be subject to prepayment in whole, but not in part,
on any Distribution Date relating to an Optional Purchase. Certificateholders
will receive an amount in respect of the Certificates equal to the Certificate
Balance, together with accrued interest at the Pass-Through Rate. Any such
distribution will effect early retirement of the Certificates. See "Certain
Information Regarding the Securities -- Termination."
 
MANDATORY PREPAYMENT
 
     As more fully described under "The Notes -- Events of Default," upon the
occurrence of an Event of Default (so long as an Insurer Default shall not have
occurred and be continuing), Financial Security will have the right, but not the
obligation, to cause the property of the Trust to be sold or liquidated in whole
or in
 
                                       21
<PAGE>   23
 
part, on any date or dates as Financial Security, in its sole discretion, shall
elect prior to the date on which such Event of Default is cured. Any such sale
or liquidation may cause a full or partial prepayment of the Certificates.
 
PAYING AGENTS
 
     Distributions of principal of and interest on the Certificates will be made
by the Owner Trustee or any Paying Agent or Paying Agents as the Owner Trustee
may designate from time to time. The Chase Manhattan Bank, N.A. will be
designated as the initial Paying Agent with respect to the Certificates. (Trust
Agreement, Section 3.10)
 
                  CERTAIN INFORMATION REGARDING THE SECURITIES
 
BOOK-ENTRY REGISTRATION
 
     DTC, New York, New York, will act as securities depository for the
Securities. Each Class of Notes and the Certificates will be issued as fully
registered securities registered in the name of Cede & Co. ("Cede"), the nominee
of DTC. As such, it is anticipated that the only Noteholders or
Certificateholders, as the case may be, will be Cede, as nominee of DTC. Note
Owners will not be recognized by the Indenture Trustee as "Noteholders," as such
term will be used in the Indenture. Certificate Owners will not be recognized by
the Owner Trustee as "Certificateholders," as such term will be used in the
Trust Agreement. Security Owners will only be permitted to exercise the rights
of Securityholders indirectly through DTC and its Participants, as further
described below.
 
     DTC is a limited purpose trust company organized under the laws of the
State of New York, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the Uniform Commercial Code in effect in the State of New
York and a "clearing agency" registered pursuant to the provisions of Section
17A of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). DTC
was created to hold securities for its participating members ("Participants")
and to facilitate the clearance and settlement of securities transactions
between Participants through electronic book-entry changes in accounts of its
Participants, thereby eliminating the need for physical movement of
certificates. Participants include securities brokers and dealers (including the
Underwriters), banks, trust companies and clearing corporations. Indirect access
to the DTC system also is available to banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly (the "Indirect Participants"). The
rules applicable to DTC and its Participants are on file with the Commission.
 
     Security Owners that are not Participants or Indirect Participants but
desire to purchase, sell or otherwise transfer ownership of, or an interest in,
Securities may do so only through Participants and Indirect Participants.
Participants will receive a credit for the related Securities on DTC's records.
The ownership interest of each Security Owner will in turn be recorded on the
respective records of Participants and Indirect Participants. Security Owners
will not receive written confirmation from DTC of their purchase, but Security
Owners are expected to receive written confirmations providing details of the
transaction, as well as periodic statements of their holdings, from the
Participant or Indirect Participant through which the Security Owner entered
into the transaction. Transfers of ownership interests in the Securities will be
accomplished by entries made on the books of Participants acting on behalf of
Security Owners.
 
     To facilitate subsequent transfers, all Securities deposited by
Participants with DTC will be registered in the name of Cede, as nominee of DTC.
The deposit of Securities with DTC and their registration in the name of Cede
will effect no change in beneficial ownership. DTC will have no knowledge of the
actual Security Owners and its records will reflect only the identity of the
Participants to whose accounts such Securities are credited, which may or may
not be the Security Owners. Participants and Indirect Participants will remain
responsible for keeping account of their holdings on behalf of their customers.
 
                                       22
<PAGE>   24
 
     Conveyance of notices and other communications by DTC to Participants, by
Participants to Indirect Participants and by Participants and Indirect
Participants to Security Owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements as may be in effect from
time to time.
 
     DTC's practice is to credit Participants' accounts on each Distribution
Date in accordance with their respective holdings of Securities shown on DTC's
records unless DTC has reason to believe that it will not receive payment on
such Distribution Date. Payments by Participants and Indirect Participants to
Security Owners will be governed by standing instructions and customary
practices, as is the case with securities held for the accounts of customers in
bearer form or registered in "street name," and will be the responsibility of
such Participant or Indirect Participant and not of DTC, the Indenture Trustee,
the Owner Trustee, Financial Security or the Seller, subject to any statutory or
regulatory requirements as may be in effect from time to time. Payment of
principal of and interest on the Securities to DTC will be the responsibility of
the related Trustee, disbursement of such payments to Participants will be the
responsibility of DTC and disbursement of such payments to Security Owners will
be the responsibility of Participants and Indirect Participants. As a result,
under the book-entry format, Security Owners may experience some delay in their
receipt of payments. DTC will forward such payments to its Participants which
thereafter will forward them to Indirect Participants or Security Owners.
 
     Because DTC can only act on behalf of Participants, who in turn act on
behalf of Indirect Participants and certain banks, the ability of a Security
Owner to pledge Securities to persons or entities that do not participate in the
DTC system, or otherwise take actions with respect to such Securities, may be
limited due to the lack of a physical certificate for such Securities.
 
     Neither DTC nor Cede will consent or vote with respect to the Securities.
Under its usual procedures, DTC will mail an "Omnibus Proxy" to the Indenture
Trustee or the Owner Trustee, as the case may be, as soon as possible after each
applicable record date for such a consent or vote. The Omnibus Proxy will assign
Cede's consenting or voting rights to those Participants to whose accounts the
related Securities will be credited on that record date (identified in a listing
attached to the Omnibus Proxy).
 
     None of the Master Servicer, the Seller, Financial Security, the Indenture
Trustee or the Owner Trustee will have any liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of the Securities held by Cede, as nominee for DTC, or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.
 
   
DTC'S YEAR 2000 EFFORTS
    
 
   
     DTC management is aware that some computer applications, systems, and the
like for processing data ("Systems") that are dependent upon calendar dates,
including dates before, on, and after January 1, 2000, may encounter "Year 2000
problems." DTC has informed its Participants and other members of the financial
community (the "Industry") that it has developed and is implementing a program
so that its Systems, as the same relate to the timely payment of distributions
(including principal and income payments) to securityholders, book-entry
deliveries, and settlement of trades within DTC ("DTC Services"), continue to
function appropriately. This program includes a technical assessment and a
remediation plan, each of which is complete. Additionally, DTC's plan includes a
testing phase, which is expected to be completed within appropriate time frames.
    
 
   
     However, DTC's ability to perform properly its services is also dependent
upon other parties, including but not limited to issuers and their agents, as
well as third party vendors from whom DTC licenses software and hardware, and
third party vendors on whom DTC relies for information of the provision of
services, including telecommunication and electrical utility service providers,
among others. DTC has informed the Industry that it is contacting (and will
continue to contact) third party vendors from whom DTC acquires services to: (i)
impress upon them the importance of such services being Year 2000 compliant; and
(ii) determine the extent of their efforts for Year 2000 remediation (and, as
appropriate, testing) of their services. In additional, DTC is in the process of
developing such contingency plans as it deems appropriate.
    
 
                                       23

     According to DTC, the foregoing information with respect to DTC has been
provided to the Industry for informational purposes only and is not intended to
serve as a representation, warranty, or contract modification of any kind.
    
 
DEFINITIVE SECURITIES
 
     Definitive Securities representing any Class of Notes or the Certificates
will be issued to the related Security Owners rather than to DTC, only if (i)
DTC is no longer willing or able to discharge its responsibilities as depository
with respect to the Securities, and neither the Indenture Trustee nor the Owner
Trustee, as the case may be, nor the Administrator is able to locate a qualified
successor, (ii) the Administrator, at its option, elects to terminate the
book-entry system with respect to the related Securities through DTC or (iii)
after an Event of Default or Servicer Default, Security Owners evidencing not
less than 51% of the voting interests of the related Securities advise the
related Trustee through DTC and its Participants in writing that the
continuation of a book-entry system through DTC or its successor is no longer in
the best interests of the related Security Owners. (Indenture, Section 2.11;
Trust Agreement, Section 3.14)
 
     Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Owner Trustee or Indenture Trustee, as the case may be,
will be required to notify the related Security Owners, through Participants, of
the availability through DTC of Definitive Securities. Upon surrender by DTC of
the certificates representing all Securities of any affected Class and the
receipt of instructions for re-registration, such Trustee will issue Definitive
Securities to the related Security Owners, who thereupon will become Noteholders
or Certificateholders, as the case may be, for all purposes of the Indenture or
the Trust Agreement, respectively. (Indenture, Section 2.11; Trust Agreement,
Section 3.14)
 
     Distributions on the Definitive Securities will thereafter be made by the
related Trustee directly to holders of such Definitive Securities in accordance
with the procedures described herein and to be set forth in the Indenture and
the Trust Agreement. Interest payments and any principal payments on the
Securities on each Distribution Date will be made to holders in whose names the
Definitive Securities were registered at the close of business on the Record
Date with respect to such Distribution Date. Distributions will be made by check
mailed to the address of such holders as they appear on the register specified
in the Trust Agreement or the Indenture, as the case may be. The final payment
on any Securities (whether Definitive Securities or Securities registered in the
name of Cede), however, will be made only upon presentation and surrender of
such Securities at the office or agency specified in the notice of final
distribution to Securityholders. The Owner Trustee or the Indenture Trustee will
mail such notice to registered Securityholders within five Business Days of
receipt from the Master Servicer of notice of termination of the Trust.
(Indenture, Section 2.07; Trust Agreement, Section 9.01)
 
     Definitive Securities will be transferable and exchangeable at the offices
of the Owner Trustee or the Indenture Trustee (or any security registrar
appointed thereby), as will be set forth in the Trust Agreement or the
Indenture, as the case may be. No service charge will be imposed for any
registration of transfer or exchange, but such Trustee may require payment of a
sum sufficient to cover any tax or other governmental charge imposed in
connection therewith. (Indenture, Section 2.04; Trust Agreement, Section 3.04)
 
PAYMENTS ON THE CONTRACTS
 
     All Net Collections on or in respect of the Contracts will be deposited in
or credited to the Collection Account or, in limited instances, the Holding
Account described under "The Accounts and Eligible Investments." Such "Net
Collections" will include all payments received by the Master Servicer on or in
respect of the Contracts due on or after the Cut-Off Date, net of late payments
in respect of which the Master Servicer has previously made an Advance or
reimbursement to the Master Servicer for Nonrecoverable Advances, and will
include (i) prepayments, Net Liquidation Proceeds and Net Insurance Proceeds;
(ii) any amounts deposited in the Collection Account (a) by the Seller to
purchase Contracts because of certain material defects in the related Contract
Documents or certain breaches in representations or warranties regarding the
Contracts to be made by the Seller in the Sale and Servicing Agreement, in
either case that materially and adversely affect the interests of the
Securityholders, the Indenture Trustee, the Owner Trustee
 
                                       24
<PAGE>   26
 
or Financial Security, or (b) by the Master Servicer to purchase Contracts
because of certain breaches in representations and warranties to be made by the
Master Servicer in the Sale and Servicing Agreement or certain breaches by the
Master Servicer in servicing procedures relating to the Contracts, in each case
that materially and adversely affect such Contracts; (iii) any amounts deposited
by the Seller in the Collection Account as a result of exercising its right
under certain circumstances to purchase all of the outstanding Contracts; and
(iv) any Advances that may be made by the Master Servicer in respect of
delinquent Contracts. "Net Liquidation Proceeds" will be proceeds received by
the Master Servicer (net of Liquidation Expenses) upon liquidation of any
Defaulted Contract. "Liquidation Expenses" will be the reasonable out-of-pocket
expenses (exclusive of overhead expenses) incurred by the Master Servicer in
realizing upon a defaulted Contract. "Net Insurance Proceeds" will be proceeds
paid by any insurer under a comprehensive and collision or limited dual interest
insurance related to a Contract (other than funds used for the repair of the
related Financed Vehicle or otherwise released to the related Obligor in
accordance with normal servicing procedures), after reimbursement to the Master
Servicer of expenses recoverable under such insurance policy. (Sale and
Servicing Agreement, Section 5.02)
 
     Subject to the remainder of this paragraph, distributions on the Securities
will be made on each Distribution Date out of Net Collections (exclusive of
amounts representing payments due in the Due Period in which such Distribution
Date occurs and any future Due Periods) for the related Due Period plus certain
reinvestment earnings on Eligible Investments and any Advance made by the Master
Servicer as described under "The Master Servicer -- Advances." The amount of
such Net Collections, reinvestment earnings and Advances on each Distribution
Date will be applied as described under "Distributions on the Securities."
Amounts, to the extent available, will be withdrawn from the Spread Account to
cover any shortfalls in distributions to Securityholders. Under the Policies,
Financial Security will be obligated to provide for distribution on the
Securities on each Distribution Date the amount, if any, by which the amount of
such Net Collections and funds available in the Spread Account is less than the
sum of the interest and principal due on the Securities for such Distribution
Date and will be obligated to provide for the payment of Guaranteed
Distributions on the Certificates on the Certificate Final Distribution Date.
 
THE ACCOUNTS AND ELIGIBLE INVESTMENTS
 
     The Collection Account. The Master Servicer will cause all collections made
on or in respect of the Contracts during a Due Period (other than amounts to be
deposited in the Holding Account as described below), net of late payments in
respect of which the Master Servicer has previously made an Advance and
reimbursements to it for Nonrecoverable Advances, to be deposited in or credited
to an account (the "Collection Account") to be established by the Master
Servicer under the Sale and Servicing Agreement. The Collection Account may,
upon prior written approval of Financial Security, be an uninsured general
ledger account or a deposit account at the Bank. Funds in the Collection Account
will be invested in a reinvestment contract (the "Reinvestment Contract") under
which the Bank will be the obligor, so long as the Reinvestment Contract is an
Eligible Investment as described below. The reinvestment earnings on the
Reinvestment Contract for each Distribution Date will be equal to the amount, if
any, by which the related payment of interest for such Distribution Date exceeds
the aggregate amount of interest (adjusted to the Pass-Through Rate) accrued on
the Contracts during the related Due Period. If the Reinvestment Contract does
not qualify as an Eligible Investment, the Indenture Trustee shall invest the
funds on deposit in the Collection Account in one or more other Eligible
Investment or Investments. Payments under the Reinvestment Contract will be
deposited in the Collection Account no later than the fifth Business Day
immediately preceding each Distribution Date. (Sale and Servicing Agreement,
Section 5.01)
 
     If an Event of Default under the Sale and Servicing Agreement has occurred
and is continuing, funds in the Collection Account eligible to be invested in
Eligible Investments will be invested at the direction of the Indenture Trustee.
"Eligible Investments" will be specified in the Sale and Servicing Agreement and
will be limited to investments which meet the criteria of each Rating Agency as
being consistent with their then-current ratings of the Securities. All income
or other gain from such investments will be promptly deposited in, and any loss
resulting from such investments shall be charged to, the Collection Account.
(Sale and Servicing Agreement, Section 5.01)
 
                                       25
<PAGE>   27
 
     The Distribution Accounts. The Master Servicer will establish and maintain
with the Indenture Trustee (i) an account, in the name of the Indenture Trustee
on behalf of the Noteholders, in which amounts released from the Collection
Account for distribution to Noteholders will be deposited and from which all
distributions to Noteholders will be made (the "Note Distribution Account") and
(ii) an account, in the name of the Owner Trustee on behalf of the
Certificateholders, in which amounts released from the Collection Account for
distribution to Certificateholders will be deposited and from which all
distributions to Certificateholders will be made (the "Certificate Distribution
Account" and, together with the Note Distribution Account, the "Distribution
Accounts"). (Sale and Servicing Agreement, Section 5.01; Trust Agreement,
Section 5.01)
 
     The Holding Account. The Master Servicer will establish an account (the
"Holding Account") into which it will deposit during each Due Period payments on
Rule of 78's Contracts that are due in one or more Due Periods subsequent to
such Due Period. Funds in the Holding Account due in the next Due Period will be
transferred to the Collection Account immediately after the next succeeding
Distribution Date. (Sale and Servicing Agreement, Sections 5.01 and 5.02)
 
DISTRIBUTIONS ON THE SECURITIES
 
     General. On or before the fifth Business Day prior to each Distribution
Date (each such date, a "Determination Date"), the Master Servicer will deliver
to the Indenture Trustee, the Owner Trustee, Financial Security and each Rating
Agency a statement (the "Distribution Date Statement") setting forth, among
other things, the following amounts with respect to the related Due Period and
such Distribution Date: (i) the amount of funds in the Collection Account
allocable to collections on the Contracts in the preceding Due Period (excluding
any Advances and Repurchase Amounts); (ii) the Repurchase Amount of all
Contracts repurchased by the Seller or the Master Servicer during the related
Due Period; (iii) the Advances made by the Master Servicer and the amounts for
which the Master Servicer is entitled to be reimbursed for unreimbursed
Advances; (iv) the amount of Net Collections; (v) the Note Interest
Distributable Amount; (vi) the Note Principal Distributable Amount; (vii) the
Certificate Interest Distributable Amount; (viii) the Certificate Principal
Distributable Amount; and (ix) the Servicing Fee.
 
     Deposits to the Distribution Accounts; Priority of Payments. On each
Distribution Date, the Master Servicer will allocate amounts on deposit in the
Collection Account with respect to the related Due Period and such Distribution
Date as described below and will instruct the Indenture Trustee to make the
following deposits and distributions in the following amounts and order of
priority:
 
          (i) to the Master Servicer, the Servicing Fee, including any unpaid
     Servicing Fees with respect to one or more prior Due Periods;
 
          (ii) to the Indenture Trustee and the Owner Trustee, any accrued and
     unpaid Trustees' fees, in each case to the extent such fees have not been
     previously paid by the Master Servicer;
 
          (iii) to the Note Distribution Account, from Net Collections (after
     giving effect to the reduction in Net Collections described in clauses (i)
     and (ii) above), the Note Interest Distributable Amount to be distributed
     to the holders of the Notes at their respective Interest Rates;
 
          (iv) to the Note Distribution Account, from Net Collections (after
     giving effect to the reduction in Net Collections described in clauses (i)
     through (iii) above), the Note Principal Distributable Amount to the
     holders of the Class A-1 Notes until the principal amount of the Class A-1
     Notes has been reduced to zero, second to the holders of the Class A-2
     Notes until the principal amount of the Class A-2 Notes has been reduced to
     zero, third to the holders of the Class A-3 Notes until the principal
     amount of the Class A-3 Notes has been reduced to zero, and fourth to the
     holders of the Class A-4 Notes until the principal amount of the Class A-4
     Notes has been reduced to zero;
 
          (v) to the Note Distribution Account, if such Distribution Date is a
     Note Final Distribution Date, the remaining principal amount of the related
     Class of Notes (after giving effect to the reduction in Net Collections
     described in clauses (i) through (iv) above) to be distributed to the
     holders of such Class of Notes;
 
                                       26
<PAGE>   28
 
          (vi) to the Certificate Distribution Account, from Net Collections
     (after giving effect to the reduction in Net Collections described in
     clauses (i) through (v) above), the Certificate Interest Distributable
     Amount to be distributed to the holders of the Certificates;
 
          (vii) to the Certificate Distribution Account, from Net Collections
     (after giving effect to the reduction in Net Collections described in
     clauses (i) through (vi) above), the Certificate Principal Distributable
     Amount to be distributed to the holders of the Certificates;
 
          (viii) to the Certificate Distribution Account, if such Distribution
     Date is the Certificate Final Distribution Date, from Net Collections
     (after giving effect to the reduction in Net Collections described in
     clauses (i) through (vii) above), the Certificate Balance, as such balance
     has been reduced by payments thereon in respect of such Distribution Date
     to be distributed to the holders of the Certificates;
 
          (ix) to Financial Security, from Net Collections (after giving effect
     to the reduction in Net Collections described in clauses (i) through (viii)
     above), any amounts owing to Financial Security in respect of all payments,
     if any, made under the Policies for which reimbursement has not yet been
     made to Financial Security and any unreimbursed fees, expenses or other
     amounts owing to Financial Security under the Insurance Agreement
     (collectively, "Unreimbursed Insurer Amounts"); and
 
          (x) in the event that the distributions described in clauses (i)
     through (ix) above have been funded exclusively from Net Collections, any
     Net Collections remaining ("Excess Amounts"), will be deposited into the
     Spread Account, until the amount on deposit therein equals the Specified
     Spread Account Balance, with any remaining Excess Amounts being distributed
     as described under "-- Withdrawals from the Spread Account."
 
     If the Notes are accelerated following an Event of Default, amounts
collected following the sale or liquidation of the property of the Trust will be
distributed in the priority described above. See "The Notes -- Events of
Default."
 
     For the purposes hereof, the following terms will have the following
meanings:
 
     The "Aggregate Scheduled Balance" will equal the sum of the Scheduled
Balances of each outstanding Contract. At the time of initial issuance of the
Securities, the initial aggregate principal amount of the Securities will equal
the Aggregate Scheduled Balance.
 
     The "Aggregate Scheduled Balance Decline" will mean, with respect to any
Distribution Date, the amount by which the Aggregate Scheduled Balance as of the
Distribution Date immediately preceding such Distribution Date (or as of the
Cut-Off Date in the case of the first Distribution Date) exceeds the Aggregate
Scheduled Balance as of such Distribution Date.
 
     The "Certificate Distributable Amount" will mean, with respect to any
Distribution Date, the sum of the Certificate Principal Distributable Amount and
the Certificate Interest Distributable Amount for such Distribution Date.
 
     The "Certificate Interest Carryover Shortfall" will mean, with respect to
any Distribution Date, the excess of the sum of the Certificate Quarterly
Interest Distributable Amount for the immediately preceding Distribution Date
and any outstanding Certificate Interest Carryover Shortfall on such preceding
Distribution Date, over the amount in respect of interest on the Certificates
that is actually deposited in the Certificate Distribution Account on such
preceding Distribution Date, plus interest on such excess, to the extent
permitted by law, at the Pass-Through Rate for the related Interest Period.
 
     The "Certificate Interest Distributable Amount" will mean, with respect to
any Distribution Date, the sum of the Certificate Quarterly Interest
Distributable Amount for such Distribution Date and the Certificate Interest
Carryover Shortfall for such Distribution Date.
 
     The "Certificate Percentage" will mean (i) for each Distribution Date to
and including the Distribution Date on which the principal amount of the Class
A-4 Notes is reduced to zero, 0% and (ii) for each Distribution Date on and
after the Distribution Date on which the principal amount of the Class A-4 Notes
is reduced to zero, a percentage equal to 100% minus the Note Percentage for
such Distribution Date.

     The "Certificate Principal Carryover Shortfall" will mean, as of the close
of any Distribution Date, the excess of the sum of the Certificate Quarterly
Principal Distributable Amount and any outstanding Certificate Principal
Carryover Shortfall for the immediately preceding Distribution Date, over the
amount in respect of principal that is actually deposited in the Certificate
Distribution Account on such Distribution Date.
 
     The "Certificate Principal Distributable Amount" will mean, with respect to
any Distribution Date, the sum of the Certificate Quarterly Principal
Distributable Amount for such Distribution Date and any outstanding Certificate
Principal Carryover Shortfall for the immediately preceding Distribution Date;
provided, however, that the Certificate Principal Distributable Amount shall not
exceed the Certificate Balance. In addition, on the Certificate Final
Distribution Date, the principal required to be deposited into the Certificate
Distribution Account will include the amount necessary to reduce the Certificate
Balance to zero.
 
     The "Certificate Quarterly Interest Distributable Amount" will mean, with
respect to any Distribution Date, 90 days of interest (or, in the case of the
first Distribution Date, interest accrued from and including the Cut-Off Date to
but excluding such Distribution Date) at the Pass-Through Rate on the
Certificate Balance on the immediately preceding Distribution Date, after giving
effect to all payments of principal on such preceding Distribution Date (or, in
the case of the first Distribution Date, the Original Certificate Balance).
 
     The "Certificate Quarterly Principal Distributable Amount" will mean, with
respect to any Distribution Date, the Certificate Percentage of the Principal
Distributable Amount for such Distribution Date.
 
     A "Defaulted Contract" will mean, with respect to any Due Period, a
Contract (i) which is, at the end of such Due Period, delinquent in the amount
of at least two monthly payments or (ii) with respect to which the related
Financed Vehicle has been repossessed or repossession efforts have been
commenced.
 
     A "Due Period" will mean, with respect to any Distribution Date, the
three-month period commencing on the first day of the third month preceding the
month in which such Distribution Date occurs (or commencing on the Cut-Off Date
in the case of the first Distribution Date) to the last day of the month
immediately preceding the month in which such Distribution Date occurs.
 
     A "Liquidated Contract" will be a Contract that (i) is the subject of a
Full Prepayment; (ii) is a Defaulted Contract with respect to which the related
Financed Vehicle was repossessed and, after any cure period required by law has
expired, the Master Servicer has charged-off any losses prior to the four-month
period referenced in clause (iv) below; (iii) has been paid in full on or after
its Maturity Date; or (iv) is delinquent as to all or part of four or more
payments of Monthly P&I. Contracts that become Liquidated Contracts pursuant to
clause (ii) or (iv) above and any collections thereon will thereupon no longer
be part of the Trust, although collections thereon will be deposited in the
Collection Account.
 
     The "Note Distributable Amount" will mean, with respect to any Distribution
Date, the sum of the Note Principal Distributable Amount and the Note Interest
Distributable Amount for such Distribution Date.
 
     The "Note Interest Carryover Shortfall" will mean, with respect to any
Distribution Date and a Class of Notes, the excess, if any, of the sum of the
Note Interest Distributable Amount for such Class for the immediately preceding
Distribution Date plus any outstanding Note Interest Carryover Shortfall for
such Class on such preceding Distribution Date, over the amount in respect of
interest that is actually deposited in the Note Distribution Account with

permitted by applicable law, interest on the amount of interest due but not paid
to Noteholders of such Class on such preceding Distribution Date at the related
Interest Rate for the related Interest Period.
 
     The "Note Interest Distributable Amount" will mean, with respect to any
Distribution Date and a Class of Notes, the sum of the Note Quarterly Interest
Distributable Amount and the Note Interest Carryover Shortfall for such Class of
Notes for such Distribution Date.
 
     The "Note Percentage" will mean (i) for each Distribution Date to and
including the Distribution Date on which the principal amount of the Class A-4
Notes is reduced to zero, 100%; (ii) on the Distribution Date on which the
principal amount of the Class A-4 Notes is reduced to zero, (a) 100% until the
principal amount of the Class A-4 Notes has been reduced to zero and (b) with
respect to any remaining portion of the
 
                                       28
<PAGE>   30
 
Principal Distributable Amount, 0%; and (iii) for each Distribution Date after
the principal amount of the Class A-4 Notes is reduced to zero, 0%.
 
     The "Note Principal Carryover Shortfall" will mean, as of the close of any
Distribution Date, the excess of the sum of the Note Quarterly Principal
Distributable Amount and any outstanding Note Principal Carryover Shortfall for
the immediately preceding Distribution Date over the amount in respect of
principal that is actually deposited in the Note Distribution Account on such
Distribution Date.
 
     The "Note Principal Distributable Amount" will mean, with respect to any
Distribution Date, the sum of the Note Quarterly Principal Distributable Amount
for such Distribution Date and any outstanding Note Principal Carryover
Shortfall for the immediately preceding Distribution Date; provided, however,
that the Note Principal Distributable Amount with respect to a Class of Notes
shall not exceed the outstanding principal amount of such Class of Notes.
Notwithstanding the foregoing, the Note Principal Distributable Amount on each
Note Final Distribution Date shall not be less than the amount that is necessary
(after giving effect to other amounts to be deposited in the Note Distribution
Account on such Distribution Date and allocable to principal) to reduce the
outstanding principal amount of the related Class of Notes to zero.
 
     The "Note Quarterly Interest Distributable Amount" will mean, with respect
to any Distribution Date, 90 days of interest (or in the case of the first
Distribution Date, interest accrued from and including the Cut-Off Date to but
excluding such Distribution Date, or in the case of the Class A-1 Notes and the
Class A-2 Notes, interest for the actual number of days in the applicable
Interest Period, based on a 360-day year) at the related Interest Rate for each
Class of Notes on the outstanding principal amount of the Notes of such Class on
the immediately preceding Distribution Date, after giving effect to all payments
of principal to Noteholders of such Class on or prior to such Distribution Date
(or, in the case of the first Distribution Date, on the original principal
amount of such Class of Notes).
 
     The "Note Quarterly Principal Distributable Amount" will mean, with respect
to any Distribution Date, the Note Percentage of the Principal Distributable
Amount for such Distribution Date.
 
     The "Principal Distributable Amount" will mean, with respect to any
Distribution Date, the sum of (i) the Aggregate Scheduled Balance Decline for
such Distribution Date, plus (ii) the aggregate Scheduled Balances as of such
Distribution Date of all Rule of 78's Contracts that became Liquidated Contracts
pursuant to clause (i), (ii) or (iv) of the definition of the term "Liquidated
Contract" during the related Due Period.
 
     The "Scheduled Balance" of a Rule of 78's Contract will represent the
present value of the remaining scheduled payments of Monthly P&I due on such
Contract discounted on a monthly basis as described below, while the Scheduled
Balance of a Simple Interest Contract will be its actual principal balance. The
"Monthly P&I" for a Contract will be the installment of principal and interest
due thereunder each month (each such date, a "Due Date") and will be
substantially equal for the term of the Contract. The Scheduled Balance of a
Rule of 78's Contract for the Cut-Off Date and each Due Date will be set forth
in a schedule to the Sale and Servicing Agreement and will be equal to the
present value (determined as discussed below) at each such date of all payments
of Monthly P&I on the Contract that are due after such Due Date. Such present
value will be determined by discounting (on a monthly basis) each payment of
Monthly P&I from the last day of the month in which such payment of Monthly P&I
is due to the first day of the month in which such Due Date occurs using a
discount rate that will produce a present value at the Cut-Off Date equal to
the outstanding principal balance of the Contract as of the Cut-Off Date. The
interest rate borne by each Contract will at least equal the sum of the
weighted average of the Interest Rates and the Pass-Through Rate on the Closing
Date plus the Servicing Fee Percent.
 
PAYMENT PRIORITIES OF THE NOTES AND THE CERTIFICATES; THE SPREAD ACCOUNT
 
     General. The rights of the Securityholders to receive distributions with
respect to the Contracts will be subordinated to the rights of the Master
Servicer (to the extent that the Master Servicer has not been reimbursed for any
outstanding Advances and has not been paid all Servicing Fees), the Trustees and
certain
 
                                       29
<PAGE>   31
 
other entities (to the extent the Trustees and such other entities have not
received all Trust Fees and Expenses payable to them). In addition, the rights
of the Noteholders to receive distributions with respect to the Contracts will
be subject to the priorities set forth under "-- Distributions on the
Securities -- Deposits to the Distribution Accounts; Priority of Payments," and
the rights of the Certificateholders to receive distributions with respect to
the Contracts will be subordinated to the rights of the Noteholders, in each
case to the extent described above. Such priorities and subordination are
intended to enhance the likelihood of timely receipt by senior Securityholders
of the full amount of interest and principal required to be paid to them, and to
afford such senior Securityholders limited protection against losses in respect
of the Contracts.
 
     In the event of delinquencies or losses on the Contracts, the foregoing
protection will be effected both by the preferential right of the Noteholders to
receive, to the extent described herein, current distributions with respect to
the Contracts and by the establishment of the Spread Account. The Spread Account
will be a part of the Trust and will be a segregated trust account in the name
of the Indenture Trustee and the Indenture Trustee will have a perfected
security interest therein and in all amounts deposited in or credited to the
Spread Account as well as all Eligible Investments made with such deposits and
earnings. The Spread Account will be created with an initial deposit by the
Seller on the Closing Date of an amount equal to the Spread Account Initial
Deposit. The Spread Account will thereafter be funded by the deposit therein of
all Excess Amounts, if any, in respect of each Distribution Date.
 
     Amounts held from time to time in the Spread Account will continue to be
held for the benefit of holders of the Securities and Financial Security and may
be invested in Eligible Investments. Investment income on monies on deposit in
the Spread Account will be credited to the Spread Account. Any loss on such
investment will be charged to the Spread Account. (Sale and Servicing Agreement,
Section 5.03)
 
   
     Calculation of Specified Spread Account Balance. The "Specified Spread
Account Balance" will be calculated as of each Calculation Day and will equal 7%
of the Aggregate Scheduled Balance on such Calculation Day, except that if on
any Calculation Day (i) the Charge-Off Percentage for the three calendar month
period ending on such Calculation Day exceeds 4% or (ii) the Delinquency
Percentage for the three calendar month period ending on such Calculation Day
exceeds 2%, then the Specified Spread Account Balance shall equal 10% of the
Aggregate Scheduled Balance on such Calculation Day (but only for so long as
such Charge-Off Percentage or Delinquency Percentage thresholds continue to be
exceeded on any subsequent Calculation Day). Notwithstanding the foregoing, in
no event can the Specified Spread Account Balance be greater than $70,000,000
(10% of the Cut-off Date Aggregate Scheduled Balance) or less than $12,600,000
(the amount required by the Rating Agencies and Financial Security); provided,
however, it shall not be greater than the outstanding aggregate principal amount
of the Securities if such amount is less than $12,600,000. At no time after the
Closing Date will the Seller, WII, the Master Servicer, Financial Security or
any other entity be required to deposit funds into the Spread Account.
    
 
     The "Charge-Off Percentage" will mean, with respect to any three calendar
month period, the annualized percentage equivalent of the average of the
percentages of charged-off Contracts for each month in such period. For each
month, the percentage of charged-off Contracts shall be the percentage
equivalent of a fraction, the numerator of which is the aggregate Scheduled
Balance for such month of all Contracts that have become Liquidated Contracts
(as specified in clause (ii) or (iv) of the definition of Liquidated Contracts)
during such month, less any Net Liquidation Proceeds received during such month
(and not reflected in prior periods) with respect to such Contracts or from any
Contracts charged-off in prior periods, and the denominator of which is the
aggregate Scheduled Balance of all outstanding Contracts as of the end of the
immediately preceding month. The "Delinquency Percentage" will mean, with
respect to any three calendar month period, the average of the percentages of
delinquent Contracts for each month in such period. For each month the
percentage of delinquent Contracts shall be the percentage equivalent of a
fraction, the numerator of which is the sum of (i) the aggregate Scheduled
Balance of all outstanding Contracts 61 days or more delinquent (after taking
into account permitted extensions), plus (ii) the aggregate Scheduled Balance of
all Contracts in respect of which the related Financed Vehicles have been
repossessed but have not been liquidated (to the extent the related Contract is
not otherwise reflected in clause (i) above), and the
                                       30
<PAGE>   32
 
denominator of which is the aggregate Scheduled Balance of all outstanding
Contracts, in each case on the last day of such calendar month.
 
     The Master Servicer may, from time to time after the date of this
Prospectus, and with the approval of Financial Security, request each Rating
Agency to approve a formula for determining the Specified Spread Account Balance
that is different from that described above and would result in a decrease in
the amount of the Specified Spread Account Balance or the manner by which the
Spread Account is funded. If each Rating Agency delivers a letter to the
Indenture Trustee, the Owner Trustee and Financial Security to the effect that
the use of any such new formulation will not in and of itself result in a
qualification, reduction or withdrawal of its then-current rating of any Class
of Securities (without giving effect to the guaranty under either Policy of
payments owing to the Securityholders), then the Specified Spread Account
Balance will be determined in accordance with such new formula. The Sale and
Servicing Agreement will accordingly be amended to reflect such new calculation
without the consent of any Securityholder.
 
WITHDRAWALS FROM THE SPREAD ACCOUNT
 
     Amounts held from time to time in the Spread Account will continue to be
held for the benefit of the Noteholders, the Certificateholders and Financial
Security. On each Distribution Date funds will be withdrawn from the Spread
Account to the extent that the amount on deposit in the Note Distribution
Account with respect to any Distribution Date is less than the Note
Distributable Amount and will be deposited in the Note Distribution Account. In
addition, after giving effect to such withdrawal, funds will be withdrawn from
the Spread Account to the extent that the amount on deposit in the Certificate
Distribution Account is less than the Certificate Distributable Amount and will
be deposited in the Certificate Distribution Account. See "Payments from the
Spread Account and Under the Policies."
 
     If the amount on deposit in the Spread Account on any Calculation Day or
any Distribution Date (after giving effect to all deposits thereto or
withdrawals therefrom on such Distribution Date) is greater than the Specified
Spread Account Balance, the Indenture Trustee will distribute any excess first,
to Financial Security, to the extent of any Unreimbursed Insurer Amounts, then
to the Seller until the Seller has received from the Spread Account an aggregate
amount equal to the Spread Account Initial Deposit and to the Seller and WII in
the proportions of 99% and 1%, respectively. Upon any such distributions to
Financial Security, the Seller or WII, the Securityholders will have no further
rights in, or claims to, such amounts. (Sale and Servicing Agreement, Section
5.06)
 
     None of the Securityholders, the Indenture Trustee, the Owner Trustee, the
Seller, WII or Financial Security will be required to refund any amounts
properly distributed or paid to them, whether or not there are sufficient funds
on any subsequent Distribution Date to make full distributions to the
Securityholders. The obligations of Financial Security under the Policies will
not be diminished or otherwise affected by any amounts distributed to Financial
Security.
 
PAYMENTS FROM THE SPREAD ACCOUNT AND UNDER THE POLICIES
 
     On each Distribution Date on which the Note Distributable Amount exceeds
the amount then on deposit in the Note Distribution Account, the Noteholders
will be entitled to receive such deficiency (including amounts necessary to
reduce the outstanding principal balance of a given Class of Notes to zero on
the related Note Final Distribution Date), first, from amounts on deposit in the
Spread Account, second, if such amounts are insufficient, from amounts otherwise
payable to Certificateholders in respect of the Certificate Distributable Amount
and third, if such amounts are still insufficient, then from the payment of a
claim under the Note Policy. (Sale and Servicing Agreement, Section 5.05)
 
     On each Distribution Date on which the Certificate Distributable Amount
exceeds the amount then on deposit in the Certificate Distribution Account, the
Certificateholders will be entitled to receive such deficiency (including
amounts necessary to reduce the Certificate Balance to zero on the Certificate
Final Distribution Date), first, from amounts on deposit in the Spread Account,
and second, if such amounts are insufficient, from the payment of a claim under
the Certificate Policy. (Sale and Servicing Agreement, Section 5.05)
                                       31
<PAGE>   33
 
STATEMENTS TO SECURITYHOLDERS
 
     On or prior to each Distribution Date, the Master Servicer will prepare and
provide to the Indenture Trustee a statement to be delivered to each Noteholder
and to the Owner Trustee a statement to be delivered to each Certificateholder
on such Distribution Date (the "Statement to Securityholders"), setting forth
with respect to the related Distribution Date or Due Period, as applicable,
among other things, the following information:
 
          (i) the amount of the Noteholder's or Certificateholder's distribution
     allocable to principal (stated separately for each Class of Notes and the
     Certificates);
 
          (ii) the amount of the Noteholder's or Certificateholder's
     distribution allocable to interest (stated separately for each Class of
     Notes and the Certificates);
 
          (iii) the Aggregate Scheduled Balance as of the close of business on
     the last day of such Due Period;
 
          (iv) the amount of the Servicing Fee paid to the Master Servicer with
     respect to the related Due Period;
 
          (v) the amount of any Note Interest Carryover Shortfall, Note
     Principal Carryover Shortfall, Certificate Interest Carryover Shortfall and
     Certificate Principal Carryover Shortfall on such Distribution Date and the
     change in such amounts from those with respect to the immediately preceding
     Distribution Date;
 
          (vi) the Note Pool Factor for each Class of Notes and the Certificate
     Pool Factor, in each case as of such Distribution Date; and
 
          (vii) the balance on deposit in the Spread Account on such
     Distribution Date, after giving effect to distributions made on such
     Distribution Date, and the change in such balance from the immediately
     preceding Distribution Date.
 
     Each amount set forth pursuant to subclauses (i), (ii), (iv) and (v) above
will be expressed in the aggregate and as a dollar amount per $1,000 of original
principal amount of a Note or the original Certificate Balance of a Certificate,
as the case may be. Copies of such statements may be obtained by Security Owners
by a request in writing addressed to the related Trustee at its Corporate Trust
Office. In addition, within the prescribed period of time for tax reporting
purposes after the end of each calendar year during the term of the Sale and
Servicing Agreement, the Indenture Trustee and the Owner Trustee will mail to
each person who at any time during such calendar year shall have been a
Noteholder or a Certificateholder, as the case may be, a statement containing
the sum of the amounts described in clauses (i), (ii), (iv) and (v) above for
the purposes of such holder's preparation of federal income tax returns. See
"Certain Federal Income Tax Consequences." (Sale and Servicing Agreement,
Section 5.07)
 
EVIDENCE AS TO COMPLIANCE
 
     The Sale and Servicing Agreement. The Sale and Servicing Agreement will
provide that a firm of independent public accountants will furnish to the
Indenture Trustee and the Owner Trustee and Financial Security, on or before 90
days after the end of each fiscal year of the Master Servicer, beginning with
the fiscal year ended December 31, 1998, a statement as to compliance by the
Master Servicer during the preceding fiscal year (or since the Closing Date in
the case of the first such statement) with certain standards relating to the
servicing of the Contracts. (Sale and Servicing Agreement, Section 4.11)
 
     The Sale and Servicing Agreement will also provide for delivery to the
Indenture Trustee and the Owner Trustee and Financial Security, on or before 90
days after the end of each fiscal year of the Master Servicer, commencing with
the fiscal year ended December 31, 1998, of a certificate signed by two officers
of the Master Servicer stating that the Master Servicer has fulfilled its
obligations under the Sale and Servicing Agreement throughout the preceding
fiscal year (or since the Closing Date in the case of the first such
 
                                       32
<PAGE>   34
 
certificate) or, if there has been a default in the fulfillment of any such
obligation, describing each such default. (Sale and Servicing Agreement, Section
4.10)
 
     Copies of such statements and certificates may be obtained by
Securityholders by a request in writing addressed to the related Trustee at its
Corporate Trust Office.
 
     The Indenture. The Trust will be required to file annually with the
Indenture Trustee and Financial Security a written statement as to the
fulfillment of its obligations under the Indenture. (Indenture, Section 3.09)
 
     The Indenture Trustee will be required to mail each year to all related
Noteholders a brief report relating to, among other things, its eligibility and
qualification to continue as Indenture Trustee under the Indenture, any amounts
advanced by it under the Indenture, the amount, interest rate and maturity date
of certain indebtedness owing by the Trust to the Indenture Trustee in its
individual capacity, the property and funds physically held by such Indenture
Trustee as such and any action taken by it that materially affects the Notes and
that has not been previously reported. (Indenture, Section 7.04)
 
CERTAIN MATTERS REGARDING THE MASTER SERVICER
 
     The Sale and Servicing Agreement will provide that the Master Servicer may
not resign from its obligations and duties as Master Servicer thereunder except
upon determination that the Master Servicer's performance of such duties is no
longer permissible under applicable law. No such resignation will become
effective until (i) the Indenture Trustee or a successor servicer has assumed
the Master Servicer's servicing obligations and duties under the Sale and
Servicing Agreement and (ii) each Rating Agency confirms that the selection of
such successor master servicer will not result in the qualification, reduction
or withdrawal of its then-current rating of any Class of Securities. (Sale and
Servicing Agreement, Section 7.04)
 
     The Sale and Servicing Agreement will further provide that neither the
Master Servicer nor any of its directors, officers, employees and agents shall
be under any liability to the Trust or the Securityholders for taking any action
or for refraining from taking any action pursuant to the Sale and Servicing
Agreement, or for errors in judgment; provided, however, that neither the Master
Servicer nor any such person will be protected against any liability that would
otherwise be imposed by reason of willful misfeasance, bad faith or negligence
in the performance of duties or by reason of reckless disregard of obligations
and duties thereunder. In addition, the Sale and Servicing Agreement will
provide that the Master Servicer will be under no obligation to appear in,
prosecute or defend any legal action that is not incidental to its servicing
responsibilities under the Sale and Servicing Agreement and that, in its
opinion, may cause it to incur any expense or liability. The Master Servicer
may, however, undertake any reasonable action that it may deem necessary or
desirable in respect of the Sale and Servicing Agreement and the rights and
duties of the parties thereto and the interests of the Securityholders
thereunder. In any event, the legal expenses and costs of such action and any
liability resulting therefrom will be expenses, costs and liabilities of the
Trust, and the Master Servicer will be entitled to be reimbursed therefor out of
funds on deposit in the Collection Account. Any such indemnification or
reimbursement could reduce the amount otherwise available for distribution to
Securityholders. (Sale and Servicing Agreement, Section 7.05)
 
     Any corporation into which the Master Servicer may be merged or
consolidated, any corporation resulting from any merger, conversion or
consolidation to which the Master Servicer is a party or any corporation
succeeding to the business of the Master Servicer or the Master Servicer's
obligations as the Master Servicer, will be the successor of the Master Servicer
under the Sale and Servicing Agreement. (Sale and Servicing Agreement, Sections
7.02 and 7.04)
 
SERVICER DEFAULT
 
     "Servicer Defaults" under the Sale and Servicing Agreement will consist of
(i) a claim being made under either the Note Policy or the Certificate Policy,
(ii) any failure by the Master Servicer to deposit in or credit to the
Collection Account, either Distribution Account, the Spread Account or the
Holding Account any amount required to be so deposited or credited or to make
the required distributions therefrom, which failure
 
                                       33
<PAGE>   35
 
continues unremedied for three Business Days after written notice from the
Indenture Trustee, the Owner Trustee or Financial Security is received by the
Master Servicer or discovery by the Master Servicer; (iii) any failure by the
Master Servicer to deliver to Financial Security, the Indenture Trustee or the
Owner Trustee certain reports required by the Sale and Servicing Agreement by
the fourth Business Day prior to the related Distribution Date or to perform
certain other covenants under the Sale and Servicing Agreement; (iv) any failure
by the Master Servicer or the Seller duly to observe or perform in any material
respect any other covenant or agreement in the Sale and Servicing Agreement,
which failure materially and adversely affects the rights of Securityholders,
Financial Security, the Indenture Trustee or the Owner Trustee and which
continues unremedied for 30 days after the giving of written notice of such
failure (A) to the Master Servicer or the Seller, as the case may be, by the
Owner Trustee, the Indenture Trustee or Financial Security or (B) to the Master
Servicer or the Seller, as the case may be, and to the Indenture Trustee or the
Owner Trustee by holders of Notes evidencing not less than 25% of the voting
interests thereof, voting together as a single class, or, if the Notes have been
paid in full, by the holders of Certificates evidencing not less than 25% of the
voting interests thereof or, so long as no default under either Policy has
occurred and is continuing and no insolvency of Financial Security has occurred,
by Financial Security; (v) certain events of insolvency, readjustment of debt,
marshalling of assets and liabilities or similar proceedings and certain actions
by the Seller or the Master Servicer indicating its insolvency, reorganization
pursuant to bankruptcy or similar proceedings or inability to pay its
obligations (each, an "Insolvency Event"); and (vi) any material breach of any
of the representations and warranties of the Master Servicer or the Seller
(except for any breaches relating to Contracts repurchased by the Seller or the
Master Servicer) that has a material adverse effect on the Noteholders or the
Certificateholders and, within 30 days after written notice thereof shall have
been given to the Master Servicer or the Seller by the Indenture Trustee or the
Owner Trustee or by holders of Notes (voting together as a single class) or
Certificates evidencing not less than 25% of the respective voting interests
thereof or, so long as no default under either Policy has occurred and is
continuing and no insolvency of Financial Security has occurred, by Financial
Security. (Sale and Servicing Agreement, Section 8.01)
 
RIGHTS UPON SERVICER DEFAULT
 
     As long as a Servicer Default remains unremedied, the Indenture Trustee,
Financial Security or holders of Notes representing not less than 25% of the
voting interests thereof (or, if the Notes have been paid in full and the
Indenture has been discharged in accordance with its terms, by holders of
Certificates evidencing not less than 25% of the voting interests thereof),
voting together as a single class, may terminate all the rights and obligations
of the Master Servicer under the Sale and Servicing Agreement, whereupon the
Indenture Trustee will succeed, without further action, to all the
responsibilities, duties and liabilities of the Master Servicer in its capacity
as such under such agreement and will be entitled to similar compensation
arrangements. If, however, a bankruptcy trustee or similar official has been
appointed for the Master Servicer, and no Servicer Default other than such
appointment has occurred, such trustee or official may have the power to prevent
the Indenture Trustee, Financial Security or the Noteholders (or
Certificateholders) from effecting a transfer of servicing. In the event that
the Indenture Trustee is unwilling or unable so to act, it may appoint or
petition a court of competent jurisdiction to appoint a successor with a net
worth of at least $50,000,000 and whose regular business includes the servicing
of motor vehicle receivables. The Indenture Trustee may make such arrangements
for compensation to be paid, which in no event may be greater than the servicing
compensation paid to the Master Servicer under the Sale and Servicing Agreement.
Notwithstanding such termination, the Master Servicer shall be entitled to
payment of certain amounts payable to it prior to such termination, for services
rendered prior to such termination. (Sale and Servicing Agreement, Sections 8.01
and 8.02)
 
     So long as Financial Security is not in default under either Policy it may
direct the actions of the Indenture Trustee upon an Event of Default. (Sale and
Servicing Agreement, Section 8.06)
 
WAIVER OF PAST DEFAULTS
 
     The holders of Notes evidencing at least 51% of the voting interests
thereof, voting together as a single class (or, if all of the Notes have been
paid in full and the Indenture has been discharged in accordance with its terms,
the holders of Certificates evidencing not less than 51% of the voting interests
thereof), may, on
 
                                       34

behalf of all Securityholders, with the consent of Financial Security, waive any
default by the Master Servicer in the performance of its obligations under the
Sale and Servicing Agreement and its consequences, except a default in making
any required deposits to or payments from the Collection Account, the Holding
Account, the Spread Account, the Certificate Distribution Account or the Note
Distribution Account in accordance with that agreement or in respect of a
covenant or provision of that agreement that cannot be modified or amended
without the consent of each Securityholder (in which event the related waiver
will require the approval of holders of all of the Securities). No such waiver
will impair the Securityholders' rights with respect to subsequent Servicer
Defaults. (Sale and Servicing Agreement, Section 8.05)
 
VOTING INTERESTS
 
     The "voting interests" of the (i) Notes of a Class or Classes will be
allocated among the Noteholders or related Note Owners, as the case may be, in
accordance with the unpaid principal amount of the Notes of such Class or
Classes represented thereby and (ii) Certificates will be allocated among the
Certificateholders or related Certificate Owners, as the case may be, in
accordance with the Certificate Balance represented thereby; except that in
certain circumstances any Securities held by the Seller, WFS or any of their
respective affiliates shall be excluded from such determination.
 
AMENDMENT
 
     Amendment of the Sale and Servicing Agreement. The Sale and Servicing
Agreement may be amended, with the consent of Financial Security but without the
consent of the Noteholders or the Certificateholders, to cure any ambiguity,
correct or supplement any provision therein which may be inconsistent with any
other provision therein, to add any other provisions with respect to matters or
questions arising under such agreement which are not inconsistent with the
provisions thereof, to add or provide for any credit enhancement for any Class
of Securities or to permit certain changes with respect to the Specified Spread
Account Balance; provided, that any such action will not, in the opinion of
counsel satisfactory to the related Trustee, materially and adversely affect the
interests of any such Securityholder; and provided further, that in the case of
a change with respect to the Specified Spread Account Balance, the Trustee
receives a letter from S&P to the effect that its then-current rating on each
Class of Securities will not be qualified, reduced or withdrawn due to such
amendment and the Master Servicer shall provide Moody's notice of such
amendment. (Sale and Servicing Agreement, Section 10.01)
 
     The Sale and Servicing Agreement may also be amended from time to time with
the consent of the holders of Notes and Certificates evidencing not less than
51% of the respective voting interests thereof, for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
such agreement or of modifying in any manner the rights of the related
Securityholders of each Class; provided, that no such amendment may (i) except
as described above, increase or reduce in any manner the amount of or accelerate
or delay the timing of collections of payments on or in respect of the
Contracts, required distributions on the Notes or the Certificates, or the
Specified Spread Account Balance or the manner in which the Spread Account is
funded, or (ii) reduce the aforesaid percentage of the voting interests of which
the holders of any Class of Securities are required to consent to any such
amendment, without the consent of Financial Security and the holders of all of
the relevant Class of Securities. (Sale and Servicing Agreement, Section 10.01)
 
     Amendment of the Trust Agreement. The Trust Agreement may be amended, with
the consent of Financial Security but without the consent of the
Securityholders, to cure any ambiguity, to correct or supplement any provision
therein which may be inconsistent with any other provision therein, or to add
any other provisions with respect to matters or questions arising thereunder
which are not inconsistent with the provisions thereof. (Trust Agreement,
Section 11.01)
 
     The Trust Agreement may also be amended from time to time with the consent
of Securityholders evidencing not less than 51% of the respective voting
interests thereof, for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of such agreement or of
modifying in any manner the rights of the Noteholders or the Certificateholders;
provided, that no such amendment may increase or reduce in any manner the amount
of or accelerate or delay the timing of (i) collections of
                                       35
<PAGE>   37
 
payments on or in respect of the Contracts or required distributions on the
Notes or the Certificates or any Interest Rate or the Pass-Through Rate or (ii)
reduce the aforesaid percentage of the voting interests of which the holders of
any Class of Securities are required to consent to any such amendment, without
the consent of Financial Security and the holders of all of the relevant Class
of Securities. (Trust Agreement, Section 11.01)
 
     Amendment of the Indenture. The Trust and the Indenture Trustee (on behalf
of such Trust) may, without the consent of the Noteholders but with the consent
of Financial Security, enter into one or more supplemental indentures for any of
the following purposes: (i) to correct or amplify the description of the
property subject to the lien of the Indenture or to subject additional property
to the lien of the Indenture; (ii) to provide for the assumption of the Notes
and the Indenture obligations by a permitted successor to the Trust; (iii) to
add additional covenants for the benefit of the related Noteholders or to
surrender any rights or powers conferred upon the Trust; (iv) to convey,
transfer, assign, mortgage or pledge any property to the Indenture Trustee; (v)
to cure any ambiguity or correct or supplement any provision in the Indenture or
in any supplemental indenture which may be inconsistent with any other provision
in the Indenture, any supplemental indenture, the Sale and Servicing Agreement
or certain other agreements; provided, that any action specified in clause (v)
shall not adversely affect the interests of any Noteholder; (vi) to provide for
the acceptance of the appointment of a successor Indenture Trustee or to add to
or change any of the provisions of the Indenture as shall be necessary and
permitted to facilitate the administration by more than one trustee; (vii) to
modify, eliminate or add to the provisions of the Indenture in order to comply
with the Trust Indenture Act of 1939, as amended; and (viii) to add any
provisions to, change in any manner, or eliminate any of the provisions of, the
Indenture or modify in any manner the rights of Noteholders under the Indenture
provided, that any such action will not, in the opinion of counsel satisfactory
to the related Trustee, materially and adversely affect the interests of any
Noteholder or result in the creation of a new security; and further provided
that any action specified in clause (viii) shall not, as evidenced by an opinion
of counsel, adversely affect in any material respect the interests of any
Noteholder unless such Noteholder's consent is otherwise obtained as described
below. (Indenture, Section 9.01)
 
     Without the consent of the holder of each outstanding Note affected
thereby, no supplemental indenture may: (i) change the due date of any
installment of principal of or interest on any Note or reduce the principal
amount thereof, the interest rate thereon (or the method by which such interest
or principal is calculated) or the redemption price with respect thereto or
change any place of payment where or the coin or currency in which any such Note
or any interest thereon is payable; (ii) impair the right to institute suit for
the enforcement of provisions of the Indenture regarding payment; (iii) reduce
the percentage of the voting interests of the Notes, the consent of the holders

holders of which is required for any waiver of compliance with certain
provisions of the Indenture or of certain defaults thereunder and their
consequences as provided for in the Indenture; (iv) modify or alter the
provisions of the Indenture regarding the voting of Notes held by the Trust, any
other obligor on the Notes, the Seller, or any of their respective affiliates;
(v) reduce the percentage of the voting interests of the Notes, the consent of
the holders of which is required to direct the Indenture Trustee to sell or
liquidate the property of the Trust if the proceeds of such sale or liquidation
would be insufficient to pay the principal amount of and accrued but unpaid
interest on the outstanding Notes; (vi) decrease the percentage of the voting
interests of such Notes required to amend the provisions of the Indenture which
specify the applicable percentage of voting interests of the Notes necessary to
amend such Indenture or certain other related agreements; or (vii) permit the
creation of any lien ranking prior to or on a parity with the lien of the
Indenture with respect to any of the collateral for the Notes or, except as
otherwise permitted or contemplated in the Indenture, terminate the lien of such
Indenture on any such collateral or deprive the holder of any such Note of the
security afforded by the lien of such Indenture; and further provided, that any
such action will not, in the opinion of counsel satisfactory to the related
Trustee, result in the creation of a new security. (Indenture, Section 9.02)
 
LIST OF SECURITYHOLDERS
 
     Upon the written request of the Master Servicer, the Owner Trustee will
provide to the Master Servicer within 15 days after receipt of such request, a
list of the names and addresses of all Certificateholders. In
 
                                       36
<PAGE>   38
 
addition, three or more holders of Certificates or holders of Certificates
evidencing not less than 25% of the voting interests of the Certificates, upon
compliance by such Certificateholders with certain provisions of the Trust
Agreement, may request that the Owner Trustee afford such Certificateholders
access during business hours to the current list of Certificateholders for
purposes of communicating with other Certificateholders with respect to their
rights under the Trust Agreement. (Trust Agreement, Section 3.07)
 
     Three or more holders of Notes may, by written request to the Indenture
Trustee, obtain access to the list of all Noteholders maintained by such
Indenture Trustee for the purpose of communicating with the other Noteholders
with respect to their rights under the Indenture or under the Notes. The
Indenture Trustee may elect not to afford the requesting Noteholders access to
the list of Noteholders if it agrees to mail the desired communication or proxy,
on behalf of and at the expense of the requesting Noteholders, to all
Noteholders. (Indenture, Section 7.02)
 
     Neither the Trust Agreement nor the Indenture will provide for the holding
of any annual or other meetings of Securityholders.
 
TRUST; INSOLVENCY EVENT
 
     The Trust Agreement will provide that the Owner Trustee, each
Certificateholder, the Indenture Trustee and each Noteholder shall agree that
they will not at any time institute, or join in any institution against, the
Trust, the Seller or WII, any bankruptcy proceedings relating to the
Certificates, the Notes, the Trust Agreement, the Indenture or certain other
agreements. (Trust Agreement, Section 11.08)
 
TERMINATION
 
     The obligations of the Master Servicer, the Seller, the Owner Trustee and
Indenture Trustee with respect to the related Securityholders pursuant to the
Trust Agreement, Sale and Servicing Agreement or Indenture will terminate upon
the earliest to occur of (i) the maturity or other liquidation of the last
Contract and the disposition of any amounts received upon liquidation of any
property remaining in the Trust, (ii) the payment to such Securityholders of all
amounts required to be paid to them pursuant to such agreement and (iii) the
occurrence of the event described below.
 
     In order to avoid excessive administrative expenses, the Seller will be
permitted to purchase the remaining Contracts from the Trust on any Distribution
Date as of which the Aggregate Scheduled Balance is less than 5% of the Cut-Off
Date Aggregate Scheduled Balance at a price equal to the aggregate unpaid
principal balances of the related Contracts, together with accrued interest
thereon to the last Due Date in the Due Period in which such repurchase occurs.
(Sale and Servicing Agreement, Section 9.01)
 
     The Owner Trustee and Indenture Trustee will give written notice of
termination to each Securityholder of record at least 20 days prior to such
termination. The final distribution to each Securityholder will be made only
upon surrender and cancellation of such holder's Securities at the office or
agency of the related Trustee specified in the notice of termination. Any funds
remaining in the Trust at least 18 months after the date of termination and
after such Trustee has attempted to locate a Securityholder and such measures
have failed, will be distributed to a charity designated by the Master Servicer.
 
     Any outstanding Notes will be redeemed concurrently with any Optional
Purchase described above, and the subsequent distribution to the related
Certificateholders of all amounts required to be distributed to them pursuant to
the Trust Agreement will effect early retirement of the Certificates.
 
PAYMENT IN FULL OF NOTES
 
     Upon the payment in full of all outstanding Notes and the satisfaction and
discharge of the Indenture, the Owner Trustee will succeed to all the rights of
the Indenture Trustee, and the Certificateholders will succeed to all the rights
of the Noteholders, under the Sale and Servicing Agreement, except as otherwise
provided therein. (Sale and Servicing Agreement, Section 9.01)
 
                                       37

THE TRUSTEES
 
     A Trustee may resign at any time, in which event the Administrator, or its
successor, will be obligated to appoint a successor trustee. The Administrator
may also remove the Owner Trustee or the Indenture Trustee, in each case if such
Trustee becomes insolvent or ceases to be eligible to continue as such under the
Trust Agreement or Indenture, as the case may be. In such event, the
Administrator will be obligated to appoint a successor Trustee. Any resignation
or removal of a Trustee and appointment of a successor Trustee will not become
effective until acceptance of the appointment by the successor Trustee. (Trust
Agreement, Section 10.02; Indenture, Section 6.08)
 
     Each Trustee and any of its affiliates may hold Securities in their own
names or as pledgees. For the purpose of meeting the legal requirements of
certain jurisdictions, the Administrator and the Owner Trustee or Indenture
Trustee acting jointly (or in some instances, the Owner Trustee and Indenture
Trustee acting without the Administrator) will have the power to appoint
co-trustees or separate trustees of all or any part of the Trust. In the event
of such an appointment, all rights, powers, duties and obligations conferred or
imposed upon such Trustee by the Indenture, Sale and Servicing Agreement or
Trust Agreement will be conferred or imposed upon such Trustee and such separate
trustee or co-trustee jointly, or, in any jurisdiction in which such Trustee
will be incompetent or unqualified to perform certain acts, singly upon such
separate trustee or co-trustee who will exercise and perform such rights,
powers, duties and obligations solely at the direction of such Trustee. (Trust
Agreement, Section 10.05; Indenture, Section 6.10)
 
     The Trust Agreement will further provide that WII will pay the fees of the
Owner Trustee and the Trust will, or will cause the Administrator to, pay the
fees of the Indenture Trustee. The Trust Agreement will further provide that the
Owner Trustee will be entitled to indemnification by the Master Servicer for,
and will be held harmless against, any loss, liability or expense incurred by
such Trustee not resulting from its own willful misconduct, bad faith or
negligence (other than by reason of a breach of any of its representations or
warranties set forth in such agreement). The Indenture will further provide that
the Indenture Trustee will be entitled to indemnification by the Trust or the
Administrator for any loss, liability or expense incurred by such Trustee not
resulting from its own willful misconduct, negligence or bad faith. (Trust
Agreement, Section 8.02; Indenture, Section 6.07)
 
DUTIES OF THE TRUSTEES
 
     Neither Trustee will make any representations as to the validity or
sufficiency of the Trust Agreement or Indenture, the Securities issued pursuant
thereto (other than the execution and authentication thereof), or of any
Contracts or related documents, and will not be accountable for the use or
application by the Seller, WII or the Master Servicer of any funds paid to the
Seller, WII or the Master Servicer in respect of such Securities or the related
Contracts, or the investment of any monies by the Master Servicer before such
monies are deposited into the Collection Account. The Trustees will not
independently verify the existence or characteristics of the Contracts. If no
Event of Default or Servicer Default has occurred and is continuing, each
Trustee will be required to perform only those duties specifically required of
it under the Indenture, Trust Agreement or Sale and Servicing Agreement, as the
case may be. Generally those duties will be limited to the receipt of the
various certificates and reports or other instruments required to be furnished
to such Trustee under such agreements, in which case it will only be required to
examine them to determine whether they conform to the requirements of such
agreements. No Trustee will be charged with knowledge of a failure by the Master
Servicer to perform its duties under the relevant agreements which failure
constitutes an Event of Default or a Servicer Default unless such Trustee
obtains actual knowledge of such failure as specified in such agreements.
 
     No Trustee will be under any obligation to exercise any of the rights or
powers vested in it by the Indenture, Trust Agreement or Sale and Servicing
Agreement, as the case may be, or to make any investigation of matters arising
thereunder or to institute, conduct or defend any litigation thereunder or in
relation thereto at the request order or direction of any of the
Securityholders, unless such Securityholders have offered to such Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that may be incurred therein or thereby. No Securityholder will have any right
under any such agreement to institute any proceeding with respect to such
agreement, unless such holder previously has given to such
 
                                       38
<PAGE>   40
 
Trustee written notice of default and (i) the default arises from the Master
Servicer's failure to remit payments when due or (ii) the holders of Securities
evidencing not less than 25% of the voting interests of all of the related
Securities, voting together as a single class, have made written request upon
such Trustee to institute such proceeding in its own name as Trustee thereunder
and have offered to such Trustee reasonable indemnity and such Trustee for 60
days has neglected or refused to institute any such proceedings.
 
ADMINISTRATION AGREEMENT
 
     WFS, in its capacity as administrator (the "Administrator"), will enter
into an agreement (the "Administration Agreement") with the Trust, the Seller,
WII and the Indenture Trustee pursuant to which the Administrator will agree, to
the extent provided in the Administration Agreement, to provide the notices and
to perform other administrative obligations required to be provided or performed
by the Trust or the Owner Trustee under the Indenture. As compensation for the
performance of the Administrator's obligations under the Administration
Agreement and as reimbursement for its expenses related thereto, the
Administrator will be entitled to a monthly administration fee (the
"Administration Fee"), which fee will be paid by the Seller and not from the
proceeds of the Contracts or other assets of the Trust.
 
PREPAYMENT CONSIDERATIONS
 
     Because the rate of distribution of principal on the Securities will depend
on the rate of payment on the Contracts (including prepayments, liquidations and
repurchases of Contracts by the Seller or the Master Servicer under certain
conditions and the sale or liquidation of the property of the Trust under
certain conditions following the occurrence of an Event of Default), the final
distribution on each Class of Notes or the Certificates may occur earlier than
the related Final Distribution Date. The right of the Seller to repurchase all
of the Contracts upon certain events prior to the Certificate Final Distribution
Date is described under "-- Termination" and "The Master Servicer -- Repurchases
of Certain Contracts by the Master Servicer and the Seller."
 
     The law of California and most other states generally requires that retail
installment sales contracts such as the Contracts permit full and partial
prepayment without penalty, although a minimum finance charge may be applicable
in some circumstances. Any prepayments (including certain partial prepayments
not designated as advance payments by the Obligor on the related Contract) can
reduce the average life of the Contracts. The Master Servicer will permit the
sale or other transfer of a Financed Vehicle without accelerating the maturity
of the related Contract if such Contract is assumed by a person satisfying WFS'
then-current underwriting standards. See "The Master Servicer." Partial
prepayments not designated as advance payments by the Obligor on a Contract and
all partial prepayments as to Simple Interest Contracts will affect the average
life of the Contracts because those partial prepayments will be passed through
to Securityholders on the Distribution Date following the Due Period in which
they are received, while those partial prepayments designated as advance
payments for Rule of 78's Contracts only will be held until passed through in
accordance with the original schedule of payments for the related Contract or
until the amount of such partial prepayment equals the remaining principal
amount plus accrued interest due on the related Contract. Any reinvestment risk
resulting from the rate of prepayments of the Contracts and the distribution of
such prepayments to Securityholders will be borne entirely by the
Securityholders.
 
     Purchases by the Seller of Contracts because of certain material defects in
Contract documentation or due to breaches of its respective representations and
warranties in respect thereof, in either case that materially and adversely
affect the interests of Securityholders, the Indenture Trustee, the Owner
Trustee or Financial Security, and purchases by the Master Servicer of Contracts
due to certain breaches in representations and warranties made by the Master
Servicer or due to certain breaches by the Master Servicer in servicing
procedures, in either case that materially and adversely affect such Contracts
can reduce the average life of the Contracts. Any reduction in the average life
of the Securities will reduce the aggregate amount of interest received by the
Securityholders over the life of the Securities. See "The Master Servicer."
 
     While WFS does not maintain specific records for this purpose, it estimates
that, based on its experience over the past five years, the monthly prepayment
rate on the outstanding principal amount of the retail
 
                                       39
<PAGE>   41
 
installment sales contracts and installment loans secured by automobiles and
light duty trucks it has originated and serviced, for itself or others, has been
approximately 1.5%. However, no assurance can be given that the Contracts will
experience this rate of prepayment or any greater or lesser rate. WFS does not
maintain specific records which would suggest any difference in prepayment rate
for Rule of 78's Contracts as compared with Simple Interest Contracts.
 
                                  THE POLICIES
 
     The following summary of the terms of the Policies does not purport to be
complete and is qualified by reference to the Note Policy and the Certificate
Policy included as exhibits to the Registration Statement; provided, however,
the following summary describes the material terms of the Policies.
 
THE NOTE POLICY
 
     Simultaneously with the issuance of the Notes, Financial Security will
deliver the Note Policy to the Indenture Trustee for the benefit of each
Noteholder. Under the Note Policy, Financial Security will unconditionally and
irrevocably guarantee to the Indenture Trustee for the benefit of each
Noteholder the full and complete payment of (i) Scheduled Payments (as defined
below) on the Notes and (ii) the amount of any Scheduled Payment which
subsequently is avoided in whole or in part as a preference payment under
applicable law.
 
     "Scheduled Payments" will mean, with respect to any Distribution Date,
payments which are scheduled to be made on the Notes during the term of the Note
Policy in accordance with the original terms of the Notes when issued and
without regard to any subsequent amendment or modification of the Notes or of
the Indenture except amendments or modifications to which Financial Security has
given its prior written consent in an amount equal to (i) the Note Interest
Distributable Amount and (ii) the Note Principal Distributable Amount. Scheduled
Payments will not include payments which become due on an accelerated basis as a
result of (a) a default by the Trust, (b) any election to pay principal on an
accelerated basis, (c) the occurrence of an Event of Default under the Indenture
or (d) any other cause, unless Financial Security elects, in its sole
discretion, to pay in whole or in part such principal due upon acceleration,
together with any accrued interest to the date of acceleration. In the event
Financial Security does not so elect, the Note Policy will continue to guarantee
Scheduled Payments on the Notes in accordance with their original terms.
Scheduled Payments shall not include any portion of a Note Interest
Distributable Amount due to Noteholders because a notice and certificate in
proper form was not timely Received (as defined below) by Financial Security
unless, in each case, Financial Security elects, in its sole discretion, to pay
such amount in whole or in part. Scheduled Payments shall not include any
amounts due in respect of the Notes attributable to any increase in interest
rate, penalty or other sum payable by the Trust by reason of any default or any
event of default in respect of the Notes, or by reason of any deterioration of
the creditworthiness of the Trust, nor shall Scheduled Payments include, nor
shall coverage be provided under the Note Policy in respect of, any taxes,
withholding or other charge with respect to any Noteholder imposed by any
governmental authority due in connection with the payment of any Scheduled
Payment to a Noteholder.
 
     Payment of claims on the Note Policy made in respect of Scheduled Payments
will be made by Financial Security following Receipt (as defined below) by
Financial Security of the appropriate notice for payment on the later to occur
of (a) 12:00 noon, New York City time, on the fourth Business Day following
Receipt of such notice for payment, and (b) 12:00 noon, New York City time, on
the date on which such payment was due on the Notes.
 
THE CERTIFICATE POLICY
 
     Simultaneously with the issuance of the Certificates, Financial Security
will deliver the Certificate Policy to the Owner Trustee for the benefit of each
Certificateholder. Under the Certificate Policy, Financial Security will
unconditionally and irrevocably guarantee to the Owner Trustee for the benefit
of each Certificateholder the full and complete payment of (i) Guaranteed
Distributions (as defined below) with respect to the
 
                                       40
<PAGE>   42
 
Certificates and (ii) the amount of any Guaranteed Distribution which
subsequently is avoided in whole or in part as a preference payment under
applicable law.
 
     "Guaranteed Distributions" will mean, with respect to each Distribution
Date, the distributions to be made to Certificateholders (other than to WII) in
an aggregate amount equal to the Certificate Distributable Amount due and
payable on such Distribution Date in accordance with the original terms of the
Certificates when issued and without regard to any amendment or modification of
the Certificates, the Sale and Servicing Agreement or the Trust Agreement to
which Financial Security has not given its prior written consent. Guaranteed
Distributions shall not include, nor shall coverage be provided under the
Certificate Policy in respect of, any taxes, withholding or other charge imposed
with respect to any Certificateholder by any governmental authority.
 
     Payment of claims on the Certificate Policy made in respect of Guaranteed
Distributions will be made by Financial Security following Receipt (as defined
below) by Financial Security of the appropriate notice for payment on the later
to occur of (a) 12:00 noon, New York City time, on the fourth Business Day
following Receipt of such notice for payment, and (b) 12:00 noon, New York City
time, on the date on which such payment was due on the Certificates.
 
OTHER TERMS OF THE POLICIES
 
     If payment of any amount avoided as a preference under applicable
bankruptcy, insolvency, receivership or similar law is required to be made under
either Policy, Financial Security shall cause such payment to be made on the
later of (a) the date when due to be paid pursuant to the Order referred to
below or (b) the first to occur of (i) the fourth Business Day following Receipt
by Financial Security from the Indenture Trustee or the Owner Trustee, as the
case may be, of (A) a certified copy of the order (the "Order") of the court or
other governmental body which exercised jurisdiction to the effect that the
Noteholder is required to return principal or interest paid on the Notes during
the term of the Note Policy or the Certificateholder is required to return
principal or interest distributed with respect to the Certificates during the
term of the Certificate Policy, in either case because such distributions were
avoidable as preference payments under applicable bankruptcy law, (B) a
certificate of the Noteholder or Certificateholder, as the case may be, that the
Order has been entered and is not subject to any stay and (C) an assignment duly
executed and delivered by such Noteholder or Certificateholder, as the case may
be, in such form as is reasonably required by Financial Security and provided to
such Securityholder by Financial Security, irrevocably assigning to Financial
Security all rights and claims of such Securityholder relating to or arising
under the related Class of Notes or the Certificates, as the case may be,
against the debtor which made such preference payments or otherwise with respect
to such preference payment, or (ii) the date of Receipt by Financial Security
from the Indenture Trustee or the Owner Trustee, as the case may be, of the
items referred to in clauses (A), (B) and (C) above if, at least four Business
Days prior to such date of Receipt, Financial Security shall have Received
written notice from the related Trustee that such items were to be delivered on
such date and such date was specified in such notice. Such payment shall be
disbursed to the receiver, conservator, debtor-in-possession or trustee in
bankruptcy named in the Order and not to the related Trustee or any
Securityholder directly (unless a Securityholder has previously paid such amount
to the receiver, conservator, debtor-in-possession or trustee in bankruptcy
named in the Order in which case such payment shall be disbursed to the related
Trustee for distribution to such Securityholder upon proof of such payment
reasonably satisfactory to Financial Security). In connection with the
foregoing, and as will be provided in the Indenture and Sale and Servicing
Agreement, Financial Security will have certain rights to direct proceedings
regarding the seeking to avoid payments made on or in respect of the Contracts,
the Notes or the Certificates as preferential.
 
     The terms "Receipt" and "Received," with respect to either Policy, shall
mean actual delivery to Financial Security and to its fiscal agent, if any,
prior to 12:00 noon, New York City time, on a Business Day and delivery either
on a day that is not a Business Day or after 12:00 noon, New York City time,
shall be deemed to be Receipt on the next succeeding Business Day. If any notice
or certificate given under a Policy by the Indenture Trustee or the Owner
Trustee, as the case may be, is not in proper form or is not properly completed,
executed or delivered, it shall be deemed not to have been Received, and
Financial Security or its
 
                                       41
<PAGE>   43
 
fiscal agent shall promptly so advise the Indenture Trustee or the Owner
Trustee, as the case may be, and such Trustee may submit an amended notice.
 
     Under the Policies, "Business Day" will mean any day other than (i) a
Saturday or Sunday or (ii) a day on which banking institutions in The City of
New York, New York are authorized or obligated by law or executive order to be
closed.
 
     Financial Security's obligations under the Note Policy in respect of
Scheduled Payments and under the Certificate Policy in respect of Guaranteed
Distributions shall in each case be discharged to the extent funds are
transferred to the Indenture Trustee or the Owner Trustee, as the case may be,
as provided in the related Policy whether or not such funds are properly applied
by the Indenture Trustee or the Owner Trustee.
 
     Financial Security shall be subrogated to the rights of each Noteholder or
Certificateholder, as the case may be, to receive payments of principal and
interest to the extent of any payment by Financial Security under the related
Policy.
 
   
     Claims under the Policies will constitute direct, unsecured and
unsubordinated obligations of Financial Security ranking not less than pari
passu with other unsecured and unsubordinated indebtedness of Financial Security
for borrowed money. Claims against Financial Security under each other financial
guaranty insurance policy issued thereby constitute pari passu claims against
the general assets of Financial Security. The terms of the Policies cannot be
modified or altered by any other agreement or instrument, or by the merger,
consolidation or dissolution of the Trust. The Note Policy may not be cancelled
or revoked prior to distribution in full of all Scheduled Payments and the
Certificate Policy may not be cancelled or revoked prior to distribution in full
of all Guaranteed Distributions with respect to the Certificates. The Policies
are not covered by the Property/Casualty Insurance Security Fund specified in
Article 76 of the New York Insurance Law. The Policies are governed by the laws
of the State of New York. As a result, if a claim is made on the Note Policy for
the benefit of the Noteholders, or a claim is made on the Certificate Policy for
the benefit of the Certificateholders and Financial Security is insolvent and
unable to pay the amount then due under that policy, the Noteholders or
Certificateholders would not be permitted to file a claim against the Property/
Casualty Insurance Fund specified in Article 76 of the New York Insurance Law.
In that circumstance, the Noteholders or Certificateholders would have recourse
against the estate of Financial Security only, as any other general creditor of
Financial Security.

GENERAL
 
     Financial Security is a monoline insurance company incorporated in 1984
under the laws of the State of New York. Financial Security is licensed to
engage in financial guaranty insurance business in all 50 states, the District
of Columbia and Puerto Rico.
 
     Financial Security and its subsidiaries are engaged in the business of
writing financial guaranty insurance, principally in respect of securities
offered in domestic and foreign markets. In general, financial guaranty
insurance consists of the issuance of a guaranty of scheduled payments of an
issuer's securities -- thereby enhancing the credit rating of those
securities -- in consideration for the payment of a premium to the insurer.
Financial Security and its subsidiaries principally insure asset-backed,
collateralized and municipal securities. Asset-backed securities are generally
supported by residential mortgage loans, consumer or trade receivables,
securities or other assets having an ascertainable cash flow or market value.
Collateralized securities include public utility first mortgage bonds and
sale/leaseback obligation bonds. Municipal securities consist largely of general
obligation bonds, special revenue bonds and other special obligations of state
and local governments. Financial Security insures both newly issued securities
sold in the primary market and outstanding securities sold in the secondary
market that satisfy Financial Security's underwriting criteria.
 
   
     Financial Security is a wholly owned subsidiary of Financial Security
Assurance Holdings Ltd. ("Holdings"), a New York Stock Exchange listed company.
Major shareholders of Holdings include MediaOne Capital Corporation, Fund
American Enterprises Holdings, Inc., The Tokio Marine and Fire Insurance Co.,
Ltd. and EXEL Limited. No shareholder of Holdings is obligated to pay any debt
of
    
                                       42
<PAGE>   44
 
Financial Security or any claim under any insurance policy issued by Financial
Security or to make any additional contribution to the capital of Financial
Security.
 
     The principal executive offices of Financial Security are located at 350
Park Avenue, New York, New York 10022, and its telephone number at that location
is (212) 826-0100.
 
REINSURANCE
 
     Pursuant to an intercompany agreement, liabilities on financial guaranty
insurance written or reinsured from third parties by Financial Security or any
of its domestic operating insurance company subsidiaries are reinsured among
such companies on an agreed-upon percentage substantially proportional to their
respective capital, surplus and reserves, subject to applicable statutory risk
limitations. In addition, Financial Security reinsures a portion of its
liabilities under certain of its financial guaranty insurance policies with
other reinsurers under various quota share treaties and on a
transaction-by-transaction basis. Such reinsurance is utilized by Financial
Security as a risk management device and to comply with certain statutory and
rating agency requirements; it does not alter or limit Financial Security's
obligations under any financial guaranty insurance policy.
 
   
RATINGS
    
   
    
 
   
     Financial Security's insurance financial strength is rated "Aaa" by
Moody's. Financial Security's insurer financial strength is rated "AAA" by S&P
and Standard & Poor's (Australia) Pty. Ltd. Financial Security's claims-paying
ability is rated "AAA" by Fitch IBCA, Inc. and Japan Rating and Investment
Information, Inc. Such ratings reflect only the views of the respective rating
agencies, are not recommendations to buy, sell or hold securities and are
subject to revision or withdrawal at any time by such rating agencies. See "Risk

INSURANCE REGULATION
 
     Financial Security is licensed and subject to regulation as a financial
guaranty insurance corporation under the laws of the State of New York, its
state of domicile. In addition, Financial Security and its insurance
subsidiaries are subject to regulation by insurance laws of the various other
jurisdictions in which they are licensed to do business. As a financial guaranty
insurance corporation licensed to do business in the State of
 
                                       43
<PAGE>   45
 
New York, Financial Security is subject to Article 69 of the New York Insurance
Law which, among other things, limits the business of each such insurer to
financial guaranty insurance and related lines, requires that each such insurer
maintain a minimum surplus to policyholders, establishes contingency, loss and
unearned premium reserve requirements for each such insurer, and limits the size
of individual transactions ("single risks") and the volume of transactions
("aggregate risks") that may be underwritten by each such insurer. Other
provisions of the New York Insurance Law, applicable to non-life insurance
companies such as Financial Security, regulate, among other things, permitted
investments, payment of dividends, transactions with affiliates, mergers,
consolidations, acquisitions or sales of assets and incurrence of liability for
borrowings.
 
                              THE MASTER SERVICER
 
     The Contracts will be serviced by WFS in its capacity as Master Servicer.
While WFS may or may not use a Subservicer in servicing the Contracts, WFS is
referred to as the Master Servicer herein.
 
     WFS, as Master Servicer, will be obligated pursuant to the Sale and
Servicing Agreement, subject to the limitations set forth therein, to service
the Contracts and to repurchase certain of the Contracts under certain
circumstances if certain representations and warranties made by WFS are
incorrect or if WFS, as Master Servicer, breaches certain of its servicing
obligations under the Sale and Servicing Agreement, in either case in a manner
that materially and adversely affects the Securityholders. WFS, as Master
Servicer, may perform its servicing duties through one or more subservicers
(each, a "Subservicer"), provided that the employment of a Subservicer shall not
relieve the Master Servicer from any liability of the Master Servicer under the
Sale and Servicing Agreement.
 
     If WFS uses a Subservicer, WFS, as Master Servicer, will enter into a
subservicing agreement with that Subservicer. Such subservicing agreements must
not be inconsistent with the terms of the Sale and Servicing Agreement. The
Master Servicer may terminate a subservicing agreement and either service the
related Contracts directly or enter into a new subservicing agreement for such
Contracts with a Subservicer that need not be an affiliate of the Master
Servicer. Notwithstanding any subservicing agreement, the Master Servicer will
remain obligated and liable to the Indenture Trustee, the Owner Trustee and the
Securityholders for servicing and administering the Contracts in accordance with
the Sale and Servicing Agreement as if the Master Servicer alone were servicing
the Contracts. References herein to actions required or permitted to be taken by
the Master Servicer include such actions by a Subservicer. (Sale and Servicing
Agreement, Section 4.01)
 
COLLECTION OF PAYMENTS
 
     The Master Servicer will service the Contracts and will provide certain
accounting and reporting services with respect to the Contracts and the
Securities. The Master Servicer must take all actions necessary to maintain
continuous perfection of the security interests granted by the Obligors in the
Financed Vehicles. The Master Servicer will be obligated to service the
Contracts in accordance with the customary and usual servicing procedures
employed by financial institutions that service retail installment sales
contracts and/or installment loan agreements secured by motor vehicles and, to
the extent more exacting, the procedures used for such contracts owned by the
Master Servicer. In its judgment, the Master Servicer may reduce the APR of a
delinquent Contract (but not below the sum of the Pass-Through Rate and the
Servicing Fee Percent), may reduce the principal balance and may extend the
scheduled maturity of a delinquent Contract for up to 90 days in the aggregate
past the originally scheduled date of the last payment on such Contract, so long
as the Master Servicer makes an appropriate Advance as will be required in the
Sale and Servicing Agreement. (Sale and Servicing Agreement, Sections 4.01 and
4.02)
 
     The Master Servicer shall deposit in or credit to the Collection Account or
the Holding Account, within two Business Days of receipt, all Net Collections
received on or in respect of the Contracts (except that as to Contracts serviced
by a Subservicer, such proceeds shall be deposited within three Business Days of
receipt by the Subservicer). The Master Servicer will also deposit in or credit
to the Collection Account or the Holding Account, within two Business Days of
receipt, all Net Liquidation Proceeds and Net Insurance Proceeds, after
deducting therefrom the amount of any outstanding and unreimbursed Advances.

<PAGE>   46
 
Agreement, Section 4.01) See "Certain Information Regarding the
Securities -- The Accounts and Eligible Investments."
 
ADVANCES
 
     The Master Servicer will be obligated to advance delinquent payments of
Monthly P&I on individual Rule of 78's Contracts and to advance 30 days of
interest at the sum of the Pass-Through Rate and the Servicing Fee Percent for
each month of delinquency in that Due Period on individual Simple Interest
Contracts (each, an "Advance") to the extent that any such Advance, if made,
would not, in the good faith judgment of the Master Servicer, constitute a
Nonrecoverable Advance. A "Nonrecoverable Advance" will be an Advance previously
made or to be made by the Master Servicer which, in the good faith judgment of
the Master Servicer, may not be ultimately recoverable by the Master Servicer
from Liquidation Proceeds, Insurance Proceeds or otherwise. Concurrently with
the furnishing of the related Distribution Date Statement to the Indenture
Trustee and the Owner Trustee, the Master Servicer will deposit in the
Collection Account all Advances, if any, in respect of the related Due Period.
The Master Servicer will not be entitled to any interest on Advances when it is
reimbursed for Advances. The amount of Advances deposited in the Collection
Account for any Distribution Date may be net of amounts otherwise payable to the
Master Servicer on such Distribution Date. (Sale and Servicing Agreement,
Section 5.04)
 
     In making Advances, the Master Servicer will be endeavoring to maintain a
regular flow of interest and principal payments to the Securityholders rather
than to guarantee or insure against losses. Advances will be reimbursed to the
Master Servicer out of recoveries on the related Contracts (e.g., late payments
by the Obligor, Net Liquidation Proceeds and Net Insurance Proceeds) or, to the
extent any portion of an Advance is determined to be a Nonrecoverable Advance,
out of unrelated installments of Monthly P&I or prepayment proceeds.
 
INSURANCE ON FINANCED VEHICLES
 
   
     Each Obligor on a Contract is required to maintain insurance covering
physical damage to the Financed Vehicle of such Obligor in an amount not less
than the lesser of its actual cash value or the unpaid principal balance under
such Contract; provided, however, that the Master Servicer will not be obligated
to enforce this requirement when the principal balance of a Contract is less
than $4,000 or there are six or fewer months remaining to its Maturity Date. The
Master Servicer or a Subservicer is required to be named as a loss payee under
the policy of insurance obtained by the Obligor. In addition, to the extent
required by applicable law, the policy of insurance will be delivered to the
Master Servicer or Subservicer, as appropriate. The Financed Vehicle is required
to be insured against loss and damage due to fire, theft, transportation,
collision and other risks covered by comprehensive coverage. The Master Servicer
shall obtain a limited dual interest insurance policy in respect of each
Financed Vehicle that provides coverage for physical damage to, or loss of, a
Financed Vehicle if the Obligor fails to maintain the required insurance;
provided, however, that the Master Servicer shall not be required to maintain
such insurance in respect of any Financed Vehicle as to which the related
Contract has an unpaid principal balance of less than $4,000 or there are six or
fewer months remaining to its Maturity Date. (Sale and Servicing Agreement,
Section 4.04) Since Obligors may choose their own insurers to provide the
required coverage, the specific terms and conditions of their policies vary. If
the Obligor fails to obtain or maintain the required insurance, the Master
Servicer will be obligated, except when the Contract relating to such Financed
Vehicle has an unpaid principal balance of less than $4,000 or there are six or
fewer months remaining to its Maturity Date, to obtain such insurance and may
add the premium for such insurance to the balance due on the Contract to the
extent permitted by applicable law. The Scheduled Balance of a Contract will not
include any amount for such premium, and payments by an Obligor in respect of
such financed premium will not be applied to distributions on the Securities.
    
 
SERVICER DETERMINATION AND REPORTS TO TRUSTEES
 
     The Master Servicer will perform monitoring and reporting functions for the
Owner Trustee, the Indenture Trustee and Financial Security, including the
preparation and delivery to the Owner Trustee, the Indenture Trustee and
Financial Security of each Statement to Securityholders and an additional report
                                       45
<PAGE>   47
 
covering the aggregate amount, if any, paid by or due from it or the Seller for
the purchase of Contracts which it or the Seller has become obligated to
purchase and the net amount of funds which have been deposited in or credited to
the Collection Account or Holding Account. (Sale and Servicing Agreement,
Section 4.09)
 
REPURCHASES OF CERTAIN CONTRACTS BY THE MASTER SERVICER AND THE SELLER
 
     The Seller will have the option to purchase the remaining Contracts, and
thereby cause early retirement of the Securities, on any Distribution Date as of
which the Aggregate Scheduled Balance is less than 5% of the Cut-Off Date
Aggregate Scheduled Balance. See "Certain Information Regarding the
Securities -- Termination." In addition, the Seller will be required to
repurchase certain Contracts under certain circumstances if certain
representations and warranties made by the Seller are incorrect and materially
and adversely affect the interests of the Securityholders, the Indenture
Trustee, the Owner Trustee or Financial Security. The Master Servicer will be
required to purchase a Contract if it breaches certain of its servicing
obligations with respect to such Contract such that the Contract is materially
and adversely affected. Any such repurchase must be effected at a price (the
"Repurchase Amount") equal to the outstanding principal balance of such Contract
plus accrued interest thereon to the last Due Date in the Due Period in which
such repurchase occurs. (Sale and Servicing Agreement, Sections 3.02, 4.07 and
9.01)
 
SERVICING COMPENSATION
 
     The Master Servicer will be entitled to compensation for the performance of
its obligations under the Sale and Servicing Agreement. The Master Servicer
shall be entitled to receive for each Contract from the Monthly P&I paid on or
in respect of such Contract an amount (the "Servicing Fee") equal to one-twelfth
of 1.25% per annum (the "Servicing Fee Percent") of the Scheduled Balance of
such Contract for the related month in respect of which the Monthly P&I for such
month has been collected or advanced. As additional compensation, the Master
Servicer or its designee shall be entitled to retain all late payment charges,
extension fees (the Master Servicer will determine when an extension is to be
granted, subject to the limitations described under "Collection of Payments")
and similar items paid in respect of the Contracts. The Master Servicer or its
designee will receive as additional servicing compensation the amount, if any,
by which the outstanding principal balance of a Contract that is prepaid in full
prior to its maturity exceeds the Scheduled Balance of such Contract. The Master
Servicer shall pay all expenses incurred by it in connection with its servicing
activities under the Sale and Servicing Agreement and shall not be entitled to
reimbursement of such expenses except to the extent they constitute Liquidation
Expenses or expenses recoverable under an applicable insurance policy. (Sale and
Servicing Agreement, Section 4.08)
 
     The Servicing Fee will compensate the Master Servicer for performing the
functions of a third party servicer of the Contracts as an agent for the
Indenture Trustee and the Owner Trustee, including collecting and posting all
payments, responding to inquiries of Obligors, investigating delinquencies,
sending payment statements and reporting tax information to Obligors, paying
costs of collections and policing the collateral. The Servicing Fee will also
compensate the Master Servicer for administering the Contracts, including making
Advances, accounting for collections, furnishing quarterly and annual statements
to the Indenture Trustee and the Owner Trustee with respect to distributions and
generating federal income tax information and certain taxes, accounting fees,
outside auditor fees, data processing costs and other costs incurred in
connection with administering the Contracts.
 
REALIZATION UPON DEFAULTED CONTRACTS
 
     The Master Servicer will liquidate any Contract that comes into and
continues in default and as to which no satisfactory arrangements can be made
for collection of delinquent payments. Such liquidation may be through
repossession or sale of the Financed Vehicle securing such Contract or
otherwise. In connection with such repossession or other conversion, the Master
Servicer will follow such procedures as are normal and usual for holders of
motor vehicle retail installment sales contracts and installment loans. In this
regard, the Master Servicer may sell the Financed Vehicle at a repossession or
other sale. (Sale and Servicing Agreement, Section 4.03)

YEAR 2000 COMPLIANCE
    
 
   
     Many computer systems process transactions involving dates by using only
two digits to represent the year of the transaction (i.e., "98" for 1998),
rather than the full four digits of the year involved. These computer systems
could fail or produce erroneous results during the transition from 1999 to 2000.
This problem could affect a wide variety of automated information management
systems, the most critical of these functions from the perspective of the Trust
are the billing and collection systems used by the Master Servicer.
    
 
   
     The Master Servicer has advised the Seller that the Master Servicer
initiated the process of preparing its computer systems and applications to be
year 2000 compliant in 1997, including in particular those systems used in
connection with the billing and collection of Obligors as to the Contracts to be
sold to the Trust. This process involves modifying or replacing certain hardware
and software maintained by the Master Servicer, as well as communicating with
external service providers to ensure that they are taking the necessary actions
to remedy their year 2000 compliance issues. The Master Servicer has advised the
Seller that it expects to have substantially modified all of its information
management systems and applications, both hardware and software, by the end of
1998 and to have completed testing during the third quarter of 1999. The Seller
believes, based upon its discussions with the Master Servicer, that the Master
Servicer and the Master Servicer's external service providers will be year 2000
compliant with respect to the systems and applications relevant to the Master
Servicer's activities for the Trust in advance of January 1, 2000. The Master
Servicer, as an operating subsidiary of Western Financial Bank, is subject to
regulation by the Office of Thrift Supervision (the "OTS"). The OTS is providing
vigorous oversight to the year 2000 compliance activities of the thrift
institutions and their subsidiaries for which the OTS is the primary federal
supervisory agency.
    
 
   
     Based upon the information currently available to the Seller, the Seller
does not anticipate that there will be any cost to the Trust to address year
2000 issues or that such issues will have a material adverse effect upon the
cash flows due the Trust from which payments to its Securityholders will be
made. If the Master Servicer, Financial Security, the Indenture Trustee or the
Owner Trustee do not have computerized systems that are year 2000 compliant by
the year 2000, the ability to service the Contracts (in the case of the Master
Servicer), to respond to a claim (in the case of Financial Security), to make
distributions to the Noteholders (in the case of the Indenture Trustee) and to
make distributions to the Certificateholders (in the case of the Owner Trustee)
may be materially and adversely affected.
    
 
                     CERTAIN LEGAL ASPECTS OF THE CONTRACTS
 
GENERAL
 
     The Contracts are "chattel paper" as defined in the Uniform Commercial Code
as in effect in California and the other states in which the Contracts are
originated (the "UCC"). Pursuant to the UCC, an ownership interest in chattel
paper may be perfected by possession of the chattel paper or filing a UCC-1
financing statement with the Secretary of State or other central filing office
in the appropriate state as required by the applicable UCC.
 
     WFS and the Seller will take or cause to be taken such action as is
required to perfect the Trust's rights in the Contracts and will represent and
warrant that the Trust, subject to the interest of Financial Security under the
Insurance Agreement pursuant to which the Policies will be issued, has good
title, free and clear of liens and encumbrances, to each Contract on the Closing
Date. Under the Sale and Servicing Agreement, WFS, as Master Servicer (or one or
more Subservicers), will have custody of the Contracts following the sale of the
Contracts to the Trust and will hold the Contracts as bailee for the benefit of
the Trust. However, the Contracts will not be physically marked to indicate the
ownership interest thereof by the Trust. UCC-1 financing statements will be
filed with the California Secretary of State to perfect by filing and give
notice of the Trust's ownership interest in the Contracts. If, through
inadvertence or otherwise, any of the Contracts were sold to another party who
purchased such Contracts in the ordinary course of its business and took
possession of such Contracts, the purchaser would acquire an interest in the
Contracts superior to the interests of the Trust if the purchaser acquired the
Contracts in good faith, for value and without actual knowledge of the Trust's
ownership interest in the Contracts. The Master Servicer will agree in the Sale
and Servicing
 
                                       47
<PAGE>   49
 
Agreement to take all necessary action to preserve and protect the Trust's
ownership interest in the Contracts. The Seller will represent and warrant that
each Contract is secured by a Financed Vehicle. Notwithstanding the failure of
the Trust to have obtained a valid, first priority ownership interest in a
Contract, Financial Security will remain unconditionally and irrevocably
obligated on its guarantee of Scheduled Payments payable to Noteholders and
Guaranteed Distributions payable to Certificateholders on each Distribution
Date. See "The Policies."
 
SECURITY INTERESTS IN THE FINANCED VEHICLES
 
     All of the Financed Vehicles were registered in the State of California or
another of the states listed above under "The Contracts Pool" at the time of
origination of the related Contracts. Perfection of security interests in motor
vehicles is generally governed by state certificate of title statutes or by the
motor vehicle registration laws of the state in which each vehicle is located.
Security interests in vehicles registered in the State of California (the state
in which the largest number of Financed Vehicles is located) may be perfected by
depositing with the California Department of Motor Vehicles a properly endorsed
certificate of title showing the secured party as legal owner or an application
for an original registration together with an application for registration of
the secured party as legal owner. Security interests in vehicles registered in
most other states are perfected, generally, in a similar manner. California and
some other states permit the required documents to perfect a security interest
to be filed electronically as well as physically. The Seller will represent and
warrant to the Trust in the Sale and Servicing Agreement that all steps
necessary to obtain a perfected first priority security interest with respect to
the Financed Vehicles securing the Contracts have been taken. If the Master
Servicer fails, because of clerical error or otherwise, to effect or maintain
such notation for a Financed Vehicle, the Trust may not have a first priority
security interest in such Financed Vehicle.
 
     All retail installment sales contracts purchased by WFS name WFS as obligee
or assignee and as the secured party. WFS also takes all actions necessary under
the laws of the state in which the related vehicles are located to perfect its
security interest in such vehicles, including, where applicable, having a
notation of its lien recorded on the related certificate of title and obtaining
possession of the certificates of title.
 
     The Seller will sell the Contracts and assign its security interests in the
Financed Vehicles to the Trust and Financial Security. However, because of the
administrative burden and expense, neither the Trust nor Financial Security will
amend any certificate of title to identify the Trust or Financial Security as
the new secured party nor will the certificates of title be delivered to the
Trustee. Accordingly, WFS will continue to be named as the secured party on the
certificates of title for the Financed Vehicles relating to Contracts originated
by it. Under the law of California and most other states, the assignment of the
Contracts is an effective conveyance of a security interest without amendment of
any lien noted on a vehicle's certificate of title, and the new secured party
succeeds thereby to the assignor's rights as secured party. However, there
exists a risk in not identifying the Trust as the new secured party on the
certificates of title that, through fraud or negligence, the security interest
of the Trust in one or more Financed Vehicles could be released.
 
     In the absence of fraud or forgery by the Financed Vehicle owner or
administrative error by state recording officials, notation of the lien of WFS
on the certificates of title or in the electronic records of the state officials
where electronic titles are permitted, should be sufficient to protect the Trust
against the rights of subsequent purchasers of a Financed Vehicle or subsequent
lenders who take a security interest in such Financed Vehicle. If there are any
Financed Vehicles as to which WFS has failed to perfect the security interest
assigned to the Trust, such security interest would be subordinate to, among
others, subsequent purchasers of the Financed Vehicles and holders of perfected
security interests.
 
     In the event that the owner of a Financed Vehicle relocates to a state
other than the state in which the Financed Vehicle is registered, under the laws
of most states the perfected security interest in the Financed Vehicle would
continue for four months after such relocation and thereafter, in most
instances, until the owner registers the Financed Vehicle in such state. A
majority of states, including California, generally require surrender of a
certificate of title to initially register in that state a vehicle originally
registered in another state. Therefore, the Master Servicer on behalf of the
Trust must surrender possession, if it holds the certificate of title to such
Financed Vehicle, for the Financed Vehicle owner to effect the registration. If
the Financed
 
                                       48
<PAGE>   50
 
Vehicle owner moves to a state that provides for notation of lien on the
certificate of title to perfect the security interests in the Financed Vehicle,
WFS, absent clerical errors or fraud, would receive notice of surrender of the
certificate of title if WFS' lien is noted thereon. Accordingly, WFS will have
notice and the opportunity to reperfect the security interest in the Financed
Vehicle in the state of relocation. If the Financed Vehicle owner moves to a
state which does not require surrender of a certificate of title for
registration of a motor vehicle, registration in that state could defeat
perfection. In the ordinary course of servicing its portfolio of motor vehicle
loans, WFS takes steps to effect such reperfection upon receipt of notice of
reregistration or information from the obligor as to relocation. Similarly, when
an Obligor under a Contract sells a Financed Vehicle, the Master Servicer must
surrender possession of the certificate of title or will receive notice as a
result of its lien noted thereon and accordingly will have an opportunity to
require satisfaction of the related Contract before release of the lien. Under
the Sale and Servicing Agreement, the Master Servicer, at its cost, will be
obligated to maintain the continuous perfection of security interests in the
Financed Vehicles.
 
     Under the law of California and most other states, liens for unpaid taxes
and possessory liens for storage of and repairs performed on a motor vehicle
take priority even over a perfected security interest in such vehicle. The
Internal Revenue Code of 1986, as amended, also grants priority to certain
federal tax liens over the lien of a secured party. The laws of certain states
and federal law permit the confiscation of motor vehicles by governmental
authorities under certain circumstances if used in unlawful activities, which
may result in the loss of a secured party's perfected security interest in a
confiscated vehicle. The Seller will represent in the Sale and Servicing
Agreement that, as of the Closing Date, the security interest in each Financed
Vehicle is prior to all other present liens upon and security interests in such
Financed Vehicle. However, liens for repairs or taxes could arise at any time
during the term of a Contract. No notice will be given to the Trustees, the
Master Servicer or Securityholders in the event such a lien or confiscation
arises and any such lien or confiscation arising after the Closing Date would
not give rise to the Seller's repurchase obligations under the Sale and
Servicing Agreement.
 
ENFORCEMENT OF SECURITY INTERESTS IN FINANCED VEHICLES
 
     The Master Servicer, on behalf of the Trust, may take action itself or
through one or more Subservicers to enforce its security interest with respect
to defaulted Contracts by repossession and resale of the Financed Vehicles
securing such defaulted Contracts. In addition to the provisions of the UCC,
under California law the Contracts originated in California are subject to the
provisions of its Rees-Levering Motor Vehicle Sales and Finance Act (the
"Rees-Levering Act"). Contracts originated in other states are subject to retail
installment sales laws and similar laws of those states including in many of
those states their version of the Uniform Consumer Credit Code. The provisions
of the Rees-Levering Act and similar laws of other states control in the event
of a conflict with the provisions of the UCC. Under the UCC and laws applicable
in most states, a creditor can, without prior notice to the debtor, repossess a
motor vehicle securing a loan by voluntary surrender, by "self-help"
repossession without breach of peace, and by judicial process. The Rees-Levering
Act and similar laws of other states place restrictions on repossession sales,
including notice to the debtor of the intent to sell and of the debtor's right
to redeem the vehicle. In addition, the UCC requires commercial reasonableness
in the conduct of the sale.
 
     In the event of repossession and resale of a Financed Vehicle, the Master
Servicer for the benefit of the Trust would be entitled to be paid out of the
sale proceeds before such proceeds could be applied to the payment of the claims
of unsecured creditors or the holders of subsequently perfected security
interests or, thereafter, to the debtor.
 
     Under the UCC and laws applicable in most states, a creditor is entitled to
obtain a deficiency judgment from a debtor for any deficiency on repossession
and resale of the motor vehicle securing such debtor's loan. However, some
states impose prohibitions or limitations on deficiency judgments. Under
California law the proceeds from the resale of the motor vehicle securing the
debtor's loan are required to be applied first to the expenses of resale and
repossession, and if the remaining proceeds are not sufficient to repay the
indebtedness, the creditor may seek a deficiency judgment for the balance. The
priority of application of proceeds of sale as to repossessed vehicles under the
Contracts originated in most other states is similar.
 
                                       49
<PAGE>   51
 
     Certain other statutory provisions, including federal and state bankruptcy
and insolvency laws, may limit or delay the ability of a creditor to repossess
and resell collateral or enforce a deficiency judgment.
 
     In the event that deficiency judgments are not satisfied or are satisfied
at a discount or are discharged in whole or in part in bankruptcy proceedings,
including proceedings under Chapter 13 of the Bankruptcy Reform Act of 1978, as
amended, the loss will be borne by the Trust.
 
OTHER MATTERS
 
     The so-called "holder-in-due-course" rule of the Federal Trade Commission
is intended to defeat the ability of the transferor of a consumer credit
contract which is the seller of goods which give rise to the transaction (and
certain related lenders and assignees) to transfer such contract free of notice
of claims by the debtor thereunder. The effect of this rule is to subject the
assignee of such a contract to all claims and defenses which the debtor could
assert against the seller of goods. Liability under this rule, which would be
applicable to the Trust and Financial Security, is limited to amounts paid under
a Contract; however, the Obligor may also assert the rule to set off remaining
amounts due as a defense against a claim brought by the Trustee against such
Obligor.
 
     The courts have imposed general equitable principles on repossession and
litigation involving deficiency balances. These equitable principles may have an
effect of relieving an Obligor from some or all of the legal consequences of a
default.
 
     Numerous other federal and state consumer protection laws, regulations and
rules impose requirements applicable to the origination and servicing of the
Contracts, including the Truth-in-Lending Act (and Federal Reserve Board
Regulation Z), the Federal Trade Commission Act, the Fair Credit Billing Act,
the Fair Credit Reporting Act, the Equal Credit Opportunity Act (and Federal
Reserve Board Regulation B), the Fair Debt Collection Practices Act, the
Magnuson-Moss Warranty Act, state adaptations of the National Consumer Act and
of the Uniform Consumer Credit Code and the California Rees-Levering Act and
motor vehicle retail installment sale acts in other states, and similar laws and
rules. Also, the laws of certain states impose finance charge ceilings and other
restrictions on consumer transactions and require contract disclosures in
addition to those required under federal law. These requirements impose specific
statutory liabilities upon creditors who fail to comply with their provisions.
In some cases, this liability could affect the ability of an assignee such as
the Trustee to enforce consumer finance contracts such as the Contracts. The
Seller will represent and warrant in the Sale and Servicing Agreement that each
of the Contracts, and the sale of the Financed Vehicles sold thereunder,
complied with all material requirements of such laws.
 
REPURCHASE OBLIGATION
 
     Under the Sale and Servicing Agreement, the Seller will make
representations and warranties relating to validity, subsistence, perfection and
priority of the security interest in each Financed Vehicle as of the Closing
Date. Accordingly, if any defect exists in the perfection of the security
interest in any Financed Vehicle as of the Closing Date, including any defect
arising from the violation of laws or rules, and such defect materially and
adversely affects the interests of the Securityholders, the Indenture Trustee,
the Owner Trustee or Financial Security, such defect would constitute a breach
of a representation and warranty under the Sale and Servicing Agreement and, if
uncured, would create an obligation of the Seller to repurchase such Contract
unless the breach is cured. Additionally, in the Sale and Servicing Agreement
the Master Servicer will make certain representations, warranties and
affirmative covenants regarding, among other things, the maintenance of the
security interest in each Financed Vehicle, the breach of which would create an
obligation of the Master Servicer to repurchase any affected Contract unless the
breach is cured.
 
                                   THE SELLER
 
     The Seller is a wholly owned, limited-purpose operating subsidiary of WFS
which was incorporated under the laws of the State of California on October 24,
1985. The principal office of the Seller is 23 Pasteur Road, Irvine, California
92618.
 
                                       50
<PAGE>   52
 
     The Seller was organized principally for the purpose of purchasing retail
installment sales contracts and installment loans from the Bank in connection
with its activities as a finance subsidiary of the Bank. Effective May 1, 1995,
ownership of the Seller was transferred to WFS and it is now a limited purpose
operating subsidiary of WFS. The Seller has not and will not engage in any
activity other than (i) acquiring, owning, holding, selling, transferring,
assigning, pledging or otherwise dealing in installment sales contracts and
installment loans secured by automobiles and light-duty trucks or (ii)
authorizing, issuing, selling and delivering one or more series of obligations
consisting of one or more classes of bonds or pass-through certificates
collateralized by installment sales contracts and installment loans secured by
automobiles and light-duty trucks, which bonds or pass-through certificates are
rated in the highest available category by at least one nationally recognized
statistical rating agency.
 
     The Seller's Articles of Incorporation limit the activities of the Seller
to the above purposes and to any activities incidental to and necessary for such
purposes.
 
BREACH OF REPRESENTATIONS AND WARRANTIES; DEFECTIVE CONTRACT DOCUMENTATION
 
     In the Sale and Servicing Agreement, the Seller will make certain
representations and warranties with respect to each Contract as of the Closing
Date, including but not limited to, perfection, validity, enforceability of and
the absence of liens prior to the security interest granted pursuant to each
Contract, title of the Trust in and to such Contracts, validity and
enforceability of the Contracts as against the related Obligor, and collision
and comprehensive insurance coverage related to each Financed Vehicle. (Sale and
Servicing Agreement, Section 3.01) If (i) any of such representations and
warranties is found to have been incorrect as of the time it was made or any
document evidencing or securing a Contract is found to be defective or not to be
contained in the Contract files, and (ii) the same materially and adversely
affects the interest of the Certificateholders, the Indenture Trustee, the Owner
Trustee or Financial Security in and to such Contract, the Seller must cure the
defect or eliminate or otherwise cure the circumstances or condition in respect
of which such representation or warranty is incorrect within 90 days of the
discovery thereof. If the defect is not cured within such 90-day period, the
Seller must purchase the Contract affected by the defect at a price equal to the
outstanding principal amount of such Contract plus accrued interest thereon to
the last Due Date in the Due Period in which such repurchase occurs. (Sale and
Servicing Agreement, Section 3.02)
 
                                      WFS
GENERAL
 
     WFS is an auto finance company incorporated in California in 1988. WFS was
formerly known as Westcorp Financial Services, Inc. ("Westcorp Financial"), a
wholly owned subsidiary of the Bank and a licensed consumer finance company.
Prior to May 1, 1995, the auto finance activities described in this Prospectus
were conducted separately by the Bank, through its auto finance division, and by
Westcorp Financial. Effective May 1, 1995, the Bank's auto finance division was
combined with the consumer auto finance activities of Westcorp Financial, with
Westcorp Financial then changing its corporate name to WFS Financial Inc. In
August 1995, WFS completed an initial public offering of 19.7% of its common
stock. WFS is now a majority owned operating subsidiary of the Bank.
 
     WFS purchases contracts in both the prime and non-prime credit quality
segments of the auto finance market. During 1997, WFS purchased approximately
55% of its contracts from the prime credit quality segment and 45% from the
non-prime segment. WFS purchases the majority of its contracts from franchised
dealers and to a lesser extent from independent dealers. During that same
period, contracts for new and used vehicles represented 18% and 82%,
respectively, of WFS' volume of contracts purchased.
 
   
     WFS is an operating subsidiary of the Bank. As an operating subsidiary, WFS
is subject to regulation and supervision by the OTS and the Federal Deposit
Insurance Corporation ("FDIC"). At September 30, 1998, WFS had total assets of
$1,505.6 million, total liabilities of $1,341.3 million and stockholders' equity
of $164.2 million. As of September 30, 1998, WFS' net portfolio of contracts
totalled approximately $998.2 million.
    
 
     WFS' revenues are derived principally from contractual servicing fees, the
retained interest on contracts sold for which servicing is retained, interest on
contracts not sold and fee income including late fees, deferment
 
                                       51

fees, documentation fees and other fees, interest charged on its portfolio of
contracts and, to a lesser extent, gain on other investments. Interest on
borrowings and general and administrative costs are WFS' major expense items.
 
     The principal executive offices of WFS are located at 23 Pasteur Road,
Irvine, California 92618.
 
BUSINESS ACTIVITIES
 
   
     WFS is engaged principally in the business of originating contracts secured
by automobiles and light duty trucks from new and used car dealers and the
public. WFS currently conducts its operations through its principal office and
47 production offices serving 41 states.
    
 
                                      WII
 
     WII is a wholly owned limited-purpose, operating subsidiary of WFS. WII was
incorporated in California on June 11, 1996, for the purpose of purchasing an
ownership interest in the Trust and similar trusts. WII is limited by its
Articles of Incorporation from engaging in any business activities not
incidental or necessary to its stated purpose.
 
     The principal executive office of WII is located at 23 Pasteur Road,
Irvine, California 92618 and its telephone number is (949) 727-1000.

                        FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a discussion of the material federal income tax
consequences of the purchase, ownership and disposition of the Securities. This
summary is based upon laws, regulations, rulings and decisions currently in
effect, all of which are subject to change. The discussion does not deal with
all federal tax consequences applicable to all categories of investors, some of
which may be subject to special rules contained within the Internal Revenue Code
of 1986, as amended (the "Code"), and regulations promulgated thereunder.
 
     Investors should consult their own tax advisors to determine the federal,
state, local and other tax consequences of the purchase, ownership and
disposition of the Securities. Prospective investors should note that no rulings
have been or will be sought from the Internal Revenue Service (the "IRS") with
respect to any of the federal income tax consequences discussed below, and no
assurance can be given that the IRS will not take contrary positions. Moreover,
there are no cases or IRS rulings on transactions similar to those described
herein with respect to the Trust, involving both debt and equity interests
issued by a trust with terms similar to
                                       52
<PAGE>   54
 
those of the Notes and the Certificates. Prospective investors are urged to
consult their own tax advisors in determining the federal, state, local, foreign
and any other tax consequences to them of the purchase, ownership and
disposition of the Securities.
 
     This summary does not purport to deal with all aspects of federal income
taxation that may be relevant to investors in light of their individual
investment circumstances (e.g., financial institutions, broker-dealers, life
insurance companies and tax-exempt organizations).
 
TAX CHARACTERIZATION OF TRUSTS
 
     In the opinion of Mitchell, Silberberg & Knupp LLP, special tax counsel to
the Seller, the Trust will not be an association (or a publicly traded
partnership) taxable as a corporation for federal income tax purposes. This
opinion is based on the assumption that the terms of the Trust Agreement and
related documents will be complied with, and on such counsel's conclusions that
the nature of the income of the Trust will exempt it from the rule that certain
publicly traded partnerships are taxable as corporations.
 
     If the Trust were taxable as a corporation for federal income tax purposes,
it would be subject to corporate income tax on its taxable income. The Trust's
taxable income would include all its income on the related Contracts, which may
be reduced by its interest expense on the Notes. Any such corporate income tax
could materially reduce cash available to make payments on the Notes and
distributions on the Certificates, and Certificateholders could be liable for
any such tax that is unpaid by the Trust.
 
TAX CONSEQUENCES TO HOLDERS OF THE NOTES
 
     Treatment of the Notes as Indebtedness. The Seller will agree, and the
Noteholders will agree by their purchase of Notes, to treat the Notes as debt
for federal income tax purposes. Mitchell, Silberberg & Knupp LLP, special tax
counsel to the Seller, has rendered an opinion that the Notes will be classified
as debt for federal income tax purposes. All of the discussion below assumes
this characterization of the Notes is correct.
 
     OID. The discussion below assumes that all payments on the Notes are
denominated in U.S. dollars. Moreover, the discussion assumes that the interest
formula for the Notes meets the requirements for "qualified stated interest"
under Treasury regulations relating to original issue discount ("OID"), and that
any OID on the Notes (i.e., any excess of the principal amount of the Notes over
their issue price) does not exceed a de minimis amount (i.e.,  1/4% of their
principal amount multiplied by the number of full years included in their term),
all within the meaning of such OID regulations.
 
     Interest Income on the Notes. Based on the above assumptions, except as
discussed in the following paragraph, the Notes will not be considered issued
with OID. The stated interest thereon will be taxable to a Noteholder as
ordinary interest income when received or accrued in accordance with such
Noteholder's method of tax accounting. Under the OID regulations, a holder of a
Note issued with a de minimis amount of OID must include such OID in income, on
a pro rata basis, as principal payments are made on the Note. A purchaser who
buys a Note for more or less than its principal amount will generally be
subject, respectively, to the premium amortization or market discount rules of
the Code.
 
     However, because a failure to pay interest currently on the Notes is not a
default and does not give rise to a penalty, under the OID regulations the Notes
might be viewed as having been issued with OID. This interpretation would not
significantly affect accrual basis holders of Notes, although it would somewhat
accelerate taxable income to cash basis holders by in effect requiring them to
report interest income on the accrual basis.
 
     Sale or Other Disposition. If a Noteholder sells a Note, the holder will
recognize gain or loss in an amount equal to the difference between the amount
realized on the sale and the holder's adjusted tax basis in the Note. The
adjusted tax basis of a Note to a particular Noteholder will equal the holder's
cost for the Note, increased by any market discount, acquisition discount, OID
and gain previously included by such Noteholder in income with respect to the
Note and decreased by the amount of bond premium (if any) previously amortized
and by the amount of principal payments previously received by such Noteholder
with respect to such Note. Any such gain or loss will be capital gain or loss if
the Note was held as a capital asset, except for
                                       53
<PAGE>   55
 
gain representing accrued interest and accrued market discount not previously
included in income. Capital losses generally may be used only to offset capital
gains.
 
     Foreign holders. Interest payments made (or accrued) to a Noteholder who is
a nonresident alien, foreign corporation or other non-United States person (a
"foreign person") generally will be considered "portfolio interest," and
generally will not be subject to United States federal income tax and
withholding tax, if the interest is not effectively connected with the conduct
of a trade or business within the United States by the foreign person and the
foreign person (i) is not actually or constructively a "10 percent shareholder"
of the Trust or the Seller (including a holder of 10% of outstanding Notes or
Certificates) or a "controlled foreign corporation" with respect to which the
Trust or the Seller is a "related person" within the meaning of the Code and
(ii) provides the Trustee or other person who is otherwise required to withhold
U.S. tax with respect to the Notes with an appropriate statement (on Form W-8 or
a similar form), signed under penalty of perjury, certifying that the beneficial
owner of the Note is a foreign person and providing the foreign person's name
and address. If a Note is held through a securities clearing organization or
certain other financial institutions, the organization or institution may
provide the relevant signed statement to the withholding agent; in that case,
however, the signed statement must be accompanied by a Form W-8 or substitute
form provided by the foreign person that owns the Note. If such interest is not
portfolio interest, then it will be subject to United States federal income and
withholding tax at a rate of 30%, unless reduced or eliminated pursuant to an
applicable tax treaty.
 
     Any capital gain realized on the sale, redemption, retirement or other
taxable disposition of a Note by a foreign person will be exempt from United
States federal income and withholding tax, provided that (i) such gain is not
effectively connected with the conduct of a trade or business in the United
States by the foreign person and (ii) in the case of an individual foreign
person, the foreign person is not present in the United States for 183 days or
more in the taxable year.
 
     Backup Withholding. Each holder of a Note (other than an exempt holder such
as a corporation, tax exempt organization, qualified pension and profit sharing
trust, individual retirement account or nonresident alien who provides
certification as to status as a nonresident) will be required to provide, under
penalty of perjury, a certificate containing the holder's name, address, correct
federal taxpayer identification number and a statement that the holder is not
subject to backup withholding. Should a nonexempt Noteholder fail to provide the
required certification, the Trust will be required to withhold 31% of the amount
otherwise payable to the holder, and remit the withheld amount to the IRS as a
credit against the holder's federal income tax liability.
 
     Possible Alternative Treatments of the Notes. If, contrary to the opinion
of special tax counsel, the IRS successfully asserted that one or more of the
Notes did not represent debt for federal income tax purposes, the Notes might be
treated as equity interests in the Trust. If so treated, the Trust might be
treated as a publicly traded partnership taxable as a corporation with the
adverse consequences described above (and the resulting taxable corporation
would not be able to reduce its taxable income by deductions for interest
expense on Notes recharacterized as equity). Alternatively, and most likely in
the view of special tax counsel, the Trust might be treated as a publicly traded
partnership that would not be taxable as a corporation because it would meet
certain qualifying income tests. Nonetheless, treatment of the Notes as equity
interests in such a publicly traded partnership could have adverse tax
consequences to certain holders. For example, income to certain tax-exempt
entities (including pension funds) would be "unrelated business taxable income",
income to foreign holders generally would be subject to U.S. tax and U.S. tax
return filing and withholding requirements, and individual holders might be
subject to certain limitations on their ability to deduct their share of Trust
expenses.
 
TAX CONSEQUENCES TO HOLDERS OF THE CERTIFICATES
 
     Treatment of Trust as a Partnership. The Seller and the Master Servicer
will agree, and the related Certificateholders will agree by their purchase of
Certificates, to treat the Trust as a partnership for purposes of federal and
state income tax, franchise tax and any other tax measured in whole or in part
by income, with the assets of the partnership being the assets held by the
Trust, the partners of the partnership being the
 
                                       54
<PAGE>   56
 
   
Certificateholders and the Seller, and the Notes being debt of the partnership.
However, the proper characterization of the arrangement involving the Trust, the
Certificates, the Notes, the Seller and the Master Servicer is not certain
because there is no authority on transactions closely comparable to that
contemplated herein.
    
 
     A variety of alternative characterizations are possible. For example, the
Trust may be treated as a trust rather than a partnership for federal tax
purposes. Or, because the Certificates have certain features characteristic of
debt, the Certificates might be considered debt of the Seller or the Trust. Any
such characterization would not result in materially adverse tax consequences to
Certificateholders as compared to the consequences from treatment of the
Certificates as equity in a partnership, described below. The following
discussion assumes that the Certificates represent equity interests in a
partnership and that all payments on the Certificates are denominated in U.S.
dollars.
 
     Partnership Taxation. As a partnership, the Trust will not be subject to
federal income tax. Rather, each Certificateholder will be required to
separately take into account such holder's allocated share of income, gains,
losses, deductions and credits of the Trust. The Trust's income will consist
primarily of interest and finance charges earned on the related Contracts
(including appropriate adjustments for market discount, OID and bond premium)
and any gain upon collection or disposition of such Contracts. The Trust's
deductions will consist primarily of interest accruing with respect to the
Notes, servicing and other fees, and losses or deductions upon collection or
disposition of Contracts.
 
     The tax items of a partnership are allocable to the partners in accordance
with the Code, Treasury regulations and the partnership agreement (i.e., the
Trust Agreement and related documents). The Trust Agreement will provide, in
general, that the Certificateholders will be allocated taxable income of the
Trust for each month equal to the sum of (i) the interest that accrues on the
Certificates in accordance with their terms for such month, including interest
accruing at the Pass-Through Rate for such month and interest on amounts
previously due on the Certificates but not yet distributed; (ii) any Trust
income attributable to discount on the related Contracts that corresponds to any
excess of the principal amount of the Certificates over their initial issue
price; (iii) prepayment premium payable to the Certificateholders for such
month; and (iv) any other amounts of income payable to the Certificateholders
for such month. Such allocation will be reduced by any amortization by the Trust
of premium on Contracts that corresponds to any excess of the issue price of
Certificates over their principal amount. All remaining taxable income of the
Trust will be allocated to the Seller and WII, in the proportion of 99% and 1%,
respectively. Based on the economic arrangement of the parties, this approach
for allocating Trust income should be permissible under applicable Treasury
regulations, although no assurance can be given that the IRS would not require a
greater amount of income to be allocated to Certificateholders. Moreover, even
under the foregoing method of allocation, Certificateholders may be allocated
income equal to the entire Pass-Through Rate plus the other items described
above, even though the Trust might not have sufficient cash to make current cash
distributions of such amount. Thus, cash basis holders will in effect be
required to report income from the Certificates on the accrual basis and
Certificateholders may become liable for taxes on Trust income even if they have
not received cash from the Trust to pay such taxes. In addition, because tax
allocations and tax reporting will be done on a uniform basis for all
Certificateholders but Certificateholders may be purchasing Certificates at
different times and at different prices, Certificateholders may be required to
report on their tax returns taxable income that is greater or less than the
amount reported to them by the Trust.
 
     All of the taxable income allocated to a Certificateholder that is a
pension, profit sharing or employee benefit plan or other tax-exempt entity
(including an individual retirement account) will constitute "unrelated business
taxable income" generally taxable to such a holder under the Code.
 
     An individual taxpayer's share of expenses of the Trust (including fees to
the Master Servicer but not interest expense) would be miscellaneous itemized
deductions. Such deductions might be disallowed to the individual in whole or in
part and might result in such holder being taxed on an amount of income that
exceeds the amount of cash actually distributed to such holder over the life of
the Trust.
 
     The Trust intends to make all tax calculations relating to income and
allocations to Certificateholders on an aggregate basis. If the IRS were to
require that such calculations be made separately for each Contract, the
                                       55
<PAGE>   57
 
Trust might be required to incur additional expense but it is believed that
there would not be a material adverse effect on Certificateholders.
 
     Discount and Premium. It is believed that the Contracts will not be issued
with OID, and, therefore, the Trust should not have OID income. However, the
purchase price paid by the Trust for the related Contracts may be greater or
less than the remaining principal balance of the Contracts at the time of
purchase. If so, the Contracts will have been acquired at a premium or discount,
as the case may be. As indicated above, the Trust will make this calculation on
an aggregate basis, but might be required to recompute it on a Contract-by-
Contract basis.
 
     If the Trust acquires the Contracts at a market discount or premium, it
will elect to include any such discount in income currently as it accrues over
the life of such Contracts or to offset any such premium against interest income
on such Contracts. As indicated above, a portion of such market discount income
or premium deduction may be allocated to Certificateholders.
 
     Section 708 Termination. Pursuant to final Treasury regulations issued May
9, 1997, under Section 708 of the Code, a sale or exchange of 50 percent or more
of the capital and profits in the Trust would cause a deemed contribution of the
assets of the Trust (the "Old Partnership") to a new partnership (the "New
Partnership") in exchange for interests in the New Partnership. Such interests
would be deemed distributed to the partners of the Old Partnership in
liquidation thereof.
 
     Disposition of Certificates. Generally, capital gain or loss will be
recognized on a sale of Certificates in an amount equal to the difference
between the amount realized and the seller's tax basis in the Certificates sold.
A Certificateholder's tax basis in a Certificate will generally equal the
holder's cost increased by the holder's share of Trust income (includible in
income) and decreased by any distributions received with respect to such
Certificate. In addition, both the tax basis in the Certificates and the amount
realized on a sale of a Certificate would include the holder's share of the
Notes and other liabilities of the Trust. A holder acquiring Certificates at
different prices may be required to maintain a single aggregate adjusted tax
basis in such Certificates, and, upon sale or other disposition of some of the
Certificates, allocate a portion of such aggregate tax basis to the Certificates
sold (rather than maintaining a separate tax basis in each Certificate for
purposes of computing gain or loss on a sale of that Certificate).
 
     Any gain on the sale of a Certificate attributable to the holder's share of
unrecognized accrued market discount on the related Contracts would generally be
treated as ordinary income to the holder and would give rise to special tax
reporting requirements. The Trust does not expect to have any other assets that
would give rise to such special reporting requirements. Thus, to avoid those
special reporting requirements, the Trust will elect to include market discount
in income as it accrues.
 
     If a Certificateholder is required to recognize an aggregate amount of
income (not including income attributable to disallowed itemized deductions
described above) over the life of the Certificates that exceeds the aggregate
cash distributions with respect thereto, such excess will generally give rise to
a capital loss upon the retirement of the Certificates.
 
     Allocations Between Transferors and Transferees. In general, the Trust's
taxable income and losses will be determined monthly and the tax items for a
particular calendar month will be apportioned among the Certificateholders in
proportion to the principal amount of Certificates owned by them as of the close
of the last day of such month. As a result, a holder purchasing Certificates may
be allocated tax items (which will affect its tax liability and tax basis)
attributable to periods before the actual transaction.
 
     The use of such a monthly convention may not be permitted by existing
regulations. If a monthly convention is not allowed (or only applies to
transfers of less than all of the partner's interest), taxable income or losses
of the Trust might be reallocated among the Certificateholders. The Seller will
be authorized to revise the Trust's method of allocation between transferors and
transferees to conform to a method permitted by future regulations.
 
     Section 754 Election. In the event that a Certificateholder sells its
Certificates at a profit (loss), the purchasing Certificateholder will have a
higher (lower) basis in the Certificates than the selling Certificate-
 
                                       56
<PAGE>   58
 
holder had. The tax basis of the Trust's assets will not be adjusted to reflect
that higher (or lower) basis unless the Trust were to file an election under
Section 754 of the Code. In order to avoid the administrative complexities that
would be involved in keeping accurate accounting records, as well as potentially
onerous information reporting requirements, the Trust will not make such
election. As a result, Certificateholders might be allocated a greater or lesser
amount of Trust income than would be appropriate based on their own purchase
price for Certificates.
 
     Administrative Matters. The Trustee is required to keep or have kept
complete and accurate books of the Trust. Such books will be maintained for
financial reporting and tax purposes on an accrual basis and the fiscal year of
the Trust will be the calendar year. The Trustee will file a partnership
information return (IRS Form 1065) with the IRS for each taxable year of the
Trust and will report each Certificateholder's allocable share of items of Trust
income and expense to holders and the IRS on Schedule K-1. The Trust will
provide the Schedule K-l information to nominees that fail to provide the Trust
with the information statement described below and such nominees will be
required to forward such information to the beneficial owners of the
Certificates. Generally, holders must file tax returns that are consistent with
the information return filed by the Trust or be subject to penalties unless the
holder notifies the IRS of all such inconsistencies.
 
     Under Section 6031 of the Code, any person that holds Certificates as a
nominee at any time during a calendar year is required to furnish the Trust with
a statement containing certain information on the nominee, the beneficial owners
and the Certificates so held. Such information includes (i) the name, address
and taxpayer identification number of the nominee and (ii) as to each beneficial
owner (a) the name, address and identification number of such person, (b)
whether such person is a United States person, a tax-exempt entity, a foreign
government or an international organization, or any wholly owned agency or
instrumentality of either of the foregoing, and (c) certain information on
Certificates that were held, bought or sold on behalf of such person throughout
the year. In addition, brokers and financial institutions that hold Certificates
through a nominee are required to furnish directly to the Trust information as
to themselves and their ownership of Certificates. A clearing agency registered
under Section 17A of the Exchange Act is not required to furnish any such
information statement to the Trust. The information referred to above for any
calendar year must be furnished to the Trust on or before the following January
31. Nominees, brokers and financial institutions that fail to provide the Trust
with the information described above may be subject to penalties.
 
     WII will be designated as the tax matters partner for the Trust in the
Trust Agreement and, as such, will be responsible for representing the
Certificateholders in any dispute with the IRS. The Code provides for
administrative examination of a partnership as if the partnership were a
separate and distinct taxpayer. Generally, the statute of limitations for
partnership items does not expire before three years after the date on which the
partnership information return is filed. Any adverse determination following an
audit of the return of the Trust by the appropriate taxing authorities could
result in an adjustment of the returns of the Certificateholders, and, under
certain circumstances, a Certificateholder may be precluded from separately
litigating a proposed adjustment to the items of the Trust. An adjustment could
also result in an audit of a Certificateholder's returns and adjustments of
items not related to the income and losses of the Trust.
 
     Tax Consequences to Foreign Certificateholders. It is not clear whether the
Trust would be considered to be engaged in a trade or business in the United
States for purposes of federal withholding taxes with respect to non-U.S.
persons because there is no clear authority dealing with that issue under facts
substantially similar to those described herein. Although it is not expected
that the Trust would be engaged in a trade or business in the United States for
such purposes, the Trust will withhold as if it were so engaged in order to
protect the Trust from possible adverse consequences of a failure to withhold.
The Trust expects to withhold on the portion of its taxable income that is
allocable to foreign Certificateholders pursuant to Section 1446 of the Code, as
if such income were effectively connected to a U.S. trade or business, at a rate
of 35% for foreign holders that are taxable as corporations and 39.6% for all
other foreign holders. These rates may be increased by future tax legislation.
Subsequent adoption of Treasury regulations or the issuance of other
administrative pronouncements may require the Trust to change its withholding
procedures. In determining a holder's withholding status, the Trust may rely on
IRS Form W-8, IRS Form W-9 or the holder's certification of nonforeign status
signed under penalty of perjury.
 
                                       57
<PAGE>   59
 
     Each foreign holder might be required to file a U.S. individual or
corporate income tax return (including, in the case of a corporation, the branch
profits tax) on its share of the Trust's income. Each foreign holder must obtain
a taxpayer identification number from the IRS and submit that number to the
Trust on Form W-8 in order to assure appropriate crediting of the taxes
withheld. A foreign holder generally would be entitled to file with the IRS a
claim for refund with respect to taxes withheld by the Trust, taking the
position that no taxes were due because the Trust was not engaged in a U.S.
trade or business. However, interest payments made (or accrued) to a
Certificateholder who is a foreign person generally will be considered
guaranteed payments to the extent such payments are determined without regard to
the income of the Trust. If these interest payments are properly characterized
as guaranteed payments, then the interest will not be considered "portfolio
interest". As a result, Certificateholders will be subject to United States
federal income tax and withholding tax at a rate of 30%, unless reduced or
eliminated pursuant to an applicable treaty. In such case, a foreign holder
would only be entitled to claim a refund for that portion of the taxes in excess
of the taxes that should be withheld with respect to the guaranteed payments.
 
     Backup Withholding. Distributions made on the Certificates and proceeds
from the sale of the Certificates will be subject to a "backup" withholding tax
of 31% if, in general, the Certificateholder fails to comply with certain
identification procedures, unless the holder is an exempt recipient under
applicable provisions of the Code.
 
     SECURITYHOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE
SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER
TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.
 
                       CALIFORNIA INCOME TAX CONSEQUENCES
 
     In the opinion of Mitchell, Silberberg & Knupp LLP, special tax counsel to
the Seller, the Trust will not be an association taxable as a corporation for
California income tax purposes. This opinion will be based on the assumption
that the terms of the Trust Agreement and related documents will be complied
with. Mitchell, Silberberg & Knupp LLP has rendered an opinion that
Certificateholders and Noteholders who are not residents of or otherwise subject
to tax in California will not, solely by reason of their acquisition of an
interest in the Certificates or any Class of Notes, respectively, be subject to
California income, franchise, excise or similar taxes with respect to interest
on the Certificates or any Class of Notes, respectively, or with respect to any
of the other Trust Property.
 
     Investors should consult their own tax advisors to determine the state,
local and other tax consequences to them of the purchase, ownership and
disposition of the Securities.
 
                              ERISA CONSIDERATIONS
 
OVERVIEW
 
     The Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
imposes certain restrictions on employee benefit plans subject to ERISA
("Plans") and on persons who are parties in interest or disqualified persons
("parties in interest") with respect to such Plans which would affect purchases
of Securities by or on behalf of Plans. Certain employee benefit plans, such as
governmental plans and church plans (if no election has been made under Section
410(d) of the Code), are not subject to the requirements of ERISA and assets of
such plans may be invested in Certificates without regard to the ERISA
considerations described below, subject to the provisions of other applicable
federal and state law, including, for any such government or church plan
qualified under Section 401(a) of the Code and exempt from taxation under
Section 501(a) of the Code, the prohibited transaction rules set forth in
Section 503 of the Code.
 
     Investments by Plans are subject to ERISA's general fiduciary requirements,
including the requirement of investment prudence and diversification,
requirements respecting delegation of investment authority and the requirement
that a Plan's investment be made in accordance with the documents governing the
Plan.
 
                                       58
<PAGE>   60
 
PROHIBITED TRANSACTIONS
 
     Section 406 of ERISA prohibits parties in interest with respect to a Plan
from engaging in certain transactions involving a Plan and its assets unless a
statutory or administrative exemption applies to the transaction. Section 4975
of the Code and Section 502(i) of ERISA impose certain excise taxes on such
prohibited transactions. Securities purchased by a Plan would be assets of the
Plan. Under regulations issued by the U.S. Department of Labor, the Contracts in
certain circumstances may also be deemed to be assets of each Plan that
purchases Securities. If this were so, persons that cause a Plan to acquire
Securities or that sponsor or insure the related Contracts or manage, control or
service the Contracts may be subject to the fiduciary responsibility provisions
of ERISA and the prohibited transaction provisions of Section 4975 of the Code
in the absence of a statutory or administrative exemption.
 
THE NOTES
 
     The Notes may be purchased by a Plan subject to ERISA or Section 4975 of
the Code. A fiduciary of a Plan must determine that the purchase of a Note is
consistent with its fiduciary duties under ERISA and does not result in a
nonexempt prohibited transaction as defined in Section 406 of ERISA or Section
4975 of the Code.
 
     The Notes may not be purchased with the assets of a Plan if the Seller, the
Master Servicer, the Indenture Trustee, the Owner Trustee or any of their
affiliates (i) has investment or administrative discretion with respect to such
Plan assets; (ii) has authority or responsibility to give, or regularly gives,
investment advice with respect to such Plan assets, for a fee and pursuant to an
agreement or understanding that such advice (a) will serve as a primary basis
for investment decisions with respect to such Plan assets and (b) will be based
on the particular investment needs for such Plan; or (iii) is an employer
maintaining or contributing to such Plan.
 
THE CERTIFICATES
 
     The Certificates may not be acquired by (i) an employee benefit plan (as
defined in Section 3(3) of ERISA) that is subject to the provisions of Title I
of ERISA, (ii) a plan described in Section 4975(e)(1) of the Code (other than a
governmental plan described in Section 4975(g)(2) of the Code) or (iii) any
entity whose underlying assets include plan assets by reason of a plan's
investment in the entity or which uses plan assets to acquire Certificates. By
its acceptance of a Certificate or a beneficial interest therein, each
Certificateholder or Certificate Owner will be deemed to have represented and
warranted that it is not subject to the foregoing limitation.
 
     Due to the complexities of the foregoing rules and the penalties imposed
upon persons involved in prohibited transactions, it is important that the
fiduciary of an employee benefit plan considering the purchase of Certificates
consult with its counsel regarding the applicability of the prohibited
transaction provisions of ERISA and the Code to such investment.
 
     Prohibited Transaction Class Exemption ("PTCE") 95-60 was issued by the
Department of Labor on July 12, 1995 in response to the United States Supreme
Court decision John Hancock Mutual Life Insurance Co. v. Harris Trust and
Savings Bank, 510 U.S. 86 (1993), in which the Court held that assets held in an
insurance company's general account may be deemed to be "plan assets" for ERISA
purposes under certain circumstances. Subject to certain conditions, PTCE 95-60
provides general relief from the prohibited transaction rules that would
otherwise be applicable to assets held in an insurance company's general
account. Prospective insurance company purchasers should consult with their
counsel to determine whether the decision in John Hancock, as modified by PTCE
95-60, affects their ability to make purchases of the Certificates.

Rule of 78's Contract..............A Contract that provides
                                   for the payment by the
                                   Obligor of a specified
                                   total number of payments,
                                   payable in equal monthly
                                   installments, which total
                                   represents the principal
                                   amount financed plus
                                   add-on interest in an
                                   amount calculated by
                                   using the Rule of 78's.
                                   Under the Rule of 78's,
                                   the amount of a monthly
                                   payment allocable to
                                   interest on a Contract is
                                   determined by multiplying
                                   the total amount of
                                   add-on interest payable
                                   over the term of the
                                   Contract by a fraction
                                   the denominator of which
                                   is a number equal to the
                                   sum of a series of
                                   numbers representing the
                                   number of each monthly
                                   payment due under the
                                   Contract and the
                                   numerator of which for a
                                   given month is the number
                                   of payments remaining
                                   before the maturity of
                                   the Contract. For
                                   example, with a Contract
                                   providing for 12
                                   payments, the denominator
                                   of each month's fraction
                                   will be 78, the sum of a
                                   series of numbers from 1
                                   to 12. Accordingly, in
                                   the example of a twelve
                                   payment Contract, the
                                   fraction for the first
                                   payment is 12/78, for the
                                   second payment 11/78, for
                                   the third payment 10/78,
                                   and so on through the
                                   final payment, for which
                                   the fraction is 1/78. The
                                   applicable fraction is
                                   then multiplied by the
                                   total add-on interest
                                   payment over the entire
                                   term of the Contract, and
                                   the resulting amount is
                                   the amount of add-on
                                   interest earned that
                                   month. The difference
                                   between the amount of the
                                   monthly payment by the
                                   Obligor and the amount of
                                   earned add-on interest
                                   calculated for the month
                                   is applied to principal
                                   reduction. Under the law
                                   of Texas, a similar
                                   procedure is permitted
                                   for calculating the
                                   amount of add-on interest
                                   earned, except the
                                   fraction is derived by
                                   using the sum of the
                                   monthly payments rather
                                   than the sum of the
                                   number of months (the
                                   "sum of the balances").
                                   As a Contract using
                                   either the Rule of 78's
                                   or the sum of the
                                   balances method to
                                   compute interest earned
                                   is payable in equal
                                   monthly payments, the
                                   mathematical result is
                                   substantially identical
                                   under either system.
                                   Accordingly, for purposes
                                   of convenience, the term
                                   "Rule of 78's" is used
                                   herein in referring to
                                   Contracts with add-on
                                   interest regardless of
                                   which system is used to
                                   calculated interest
                                   earned.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 317(b) of the California Corporations Code (the "Corporations
Code") provides that a corporation may indemnify any person who was or is a
party or is threatened to be made a party to any "proceeding" (as defined in
Section 317(a) of the Corporations Code), other than an action by or in the
right of the corporation to procure a judgment in its favor, by reason of the
fact that such person is or was a director, officer, employee or other agent of
the corporation (collectively, an "Agent"), against expenses, judgments, fines,
settlements and other amounts actually and reasonably incurred in connection
with such proceeding if the Agent acted in good faith and in a manner the Agent
reasonably believed to be in the best interest of the corporation and, in the
case of a criminal proceeding, had no reasonable cause to believe the conduct
was unlawful.
 
     Section 317(c) of the Corporations Code provides that a corporation shall
have power to indemnify any Agent who was or is a party or is threatened to be
made a party to any threatened, pending or completed action by or in the right
of the corporation to procure a judgment in its favor by reason of the fact that
such person is or was an Agent, against expenses actually and reasonably
incurred by the Agent in connection with the defense or settlement of such
action if the Agent acted in good faith and in a manner such Agent believed to
be in the best interest of the corporation and its shareholders.
 
     Section 317(c) further provides that no indemnification may be made
thereunder for any of the following: (i) in respect of any matter as to which an
Agent shall have been adjudged to be liable to the corporation, unless the court
in which such proceeding is or was pending shall determine that such Agent is
fairly and reasonably entitled to indemnity for expenses, (ii) of amounts paid
in settling or otherwise disposing of a pending action without court approval
and (iii) of expenses incurred in defending a pending action which is settled or
otherwise disposed of without court approval.
 
     Section 317(d) of the Corporations Code requires that an Agent be
indemnified against expenses actually and reasonably incurred to the extent the
Agent has been successful on the merits in the defense of proceedings referred
to in subdivisions (b) or (c) of Section 317.
 
     Except as provided in Section 317(d), and pursuant to Section 317(e),
indemnification under Section 317 shall be made by the corporation only if
specifically authorized and upon a determination that indemnification is proper
in the circumstances because the Agent has met the applicable standard of
conduct, by any of the following: (i) a majority vote of a quorum consisting of
directors who are not parties to the proceeding, (ii) if such a quorum of
directors is not obtainable, by independent legal counsel in a written
 
                                      II-1
<PAGE>   70
 
opinion, (iii) approval of the shareholders, provided that any shares owned by
the Agent may not vote thereon, or (iv) the court in which such proceeding is or
was pending.
 
     Pursuant to Section 317(f) of the Corporations Code, the corporation may
advance expenses incurred in defending any proceeding upon receipt of an
undertaking by the Agent to repay such amount if it is ultimately determined
that the Agent is not entitled to be indemnified.
 
     Section 317(h) provides, with certain exceptions, that no indemnification
shall be made under Section 317 where it appears that it would be inconsistent
with a provision of the corporation's articles, bylaws, a shareholder resolution
or an agreement which prohibits or otherwise limits indemnification, or where it
would be inconsistent with any condition expressly imposed by a court in
approving a settlement.
 
     Section 317(i) authorizes a corporation to purchase and maintain insurance
on behalf of an Agent for liabilities arising by reason of the Agent's status,
whether or not the corporation would have the power to indemnify the Agent
against such liability under the provisions of Section 317.
 
     Registrant's Bylaws (the "Bylaws") provide for the indemnification of
officers and directors of the Registrant, to the maximum extent permitted by the
Corporations Code, against expenses, judgments, fines, settlements, and other
amounts actually and reasonably incurred in connection with any proceeding
arising by reason of the fact that such person is or was an officer or director
of the Registrant, and further provides for the advance to such officer or
director of expenses incurred by such officer or director in any such proceeding
to the maximum extent permitted by law. The Bylaws also provide that
Registrant's Board of Directors may provide for the indemnification of, or
advancement of expenses to, other Agents. Registrant's Articles of Incorporation
provide that the liability of directors of the Registrant shall be eliminated to
the fullest extent permissible under California law, but contain no specific
provisions with respect to the indemnification of, or advancement of expenses
to, Agents.
 
     Reference is also made to Section 7 of the Underwriting Agreement among
Donaldson, Lufkin & Jenrette Securities Corporation, the Registrant and WFS (see
Exhibit 1.1), which provides for indemnification of the Registrant under certain
circumstances.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes as follows:
 
          (a) To provide to the Underwriters at the closing date specified in
     the Underwriting Agreement certificates in such denominations and
     registered in such names as required by the Underwriters to provide prompt
     delivery to each purchaser.
 
          (b) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 (the "Act") may be permitted to directors, officers
     and controlling persons of the Registrant pursuant to the foregoing
     provisions, or otherwise, the Registrant has been advised that in the
     opinion of the Securities and Exchange Commission such indemnification is
     against public policy as expressed in the Act and is therefore
     unenforceable. In the event that a claim for indemnification against such
     liabilities (other than payment by the Registrant of expenses incurred or
     paid by a director, officer or controlling person of such Registrant in the
     successful defense of any action, suit or proceeding) is asserted by such
     director, officer or controlling person in connection with the securities
     being registered, the Registrant will, unless in the opinion of its counsel
     the matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by it is
     against public policy as expressed in the Act and will be governed by the
     final adjudication of such issue.
 
          (c) For purposes of determining any liability under the Act, the
     information omitted from the form of prospectus filed as part of this
     registration statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act will be deemed to be part of this registration
     statement as of the time it was declared effective.
 
          (d) For purposes of determining any liability under the Act, each
     post-effective amendment that contains a form of prospectus will be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time will be deemed to
     be the initial bona fide offering thereof.

Registrant certifies that (i) it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-3 and (ii) it reasonably believes
that the securities offered under this Registration Statement will be
"investment grade securities", as such term is defined under Transaction
Requirements B.2 of the Instructions to Form S-3, at the time of sale of such
securities, and has duly caused this Amendment No. 1 to Registration Statement

authorized, in the City of Irvine, State of California, on the 10th day of
November, 1998.

and, together with the Notes, the "Securities"). The Notes will be issued
pursuant to an indenture dated as of September 1, 1998 (the "Indenture"), among
the WFS Financial 1998-C Owner Trust (the "Trust") and Bankers Trust Company, as

September __, 1998 (the "Trust Agreement"), among the Company, WFS Investments,
Inc. ("WII"), Financial Security Assurance Inc. ("Financial Security") and Chase

      The assets of the Trust will include, among other things, (i) a pool of

secured by new and used automobiles and light-duty trucks financed thereby (the
"Financed Vehicles"), (ii) certain monies due under the Contracts on and after

("WFS"), as Master Servicer. Pursuant to the Indenture, the Trust property will
be held by the Indenture Trustee on behalf of the holders of the Notes. Pursuant
to the administration agreement dated as of September 1, 1998 (the
"Administration Agreement"), among the Company, WII, WFS, as administrator (in
such capacity, the "Administrator"), the Trust and the Indenture Trustee, the
Administrator will perform certain administrative obligations under the
Indenture. Capitalized terms used herein that are not otherwise defined shall
have the meanings ascribed thereto in the Indenture or the Sale and Servicing
Agreement, as the case may be. The Securities are more fully described in a
Registration Statement (as such term is defined in Section 1 hereof) which the
Company has furnished to the Underwriters.

      1.    Registration Statement and Prospectuses. The Company has prepared
and filed with the Securities and Exchange Commission (the "Commission") in
accordance with the provisions of the Securities Act of 1933, as amended (the
"Act"), a registration statement on Form S-3 (File No. 333-_____), including a
form of prospectus, relating to the Securities. Such registration statement has
been declared effective by the Commission. If any post-effective amendment has
been filed with respect thereto, prior to the execution and delivery of this
Agreement, the most recent such amendment has been declared effective by the
Commission. Such registration statement, as amended and the prospectus
constituting a part thereof (including in each case the information deemed to be
a part thereof pursuant to Rule 430A under the Act and all documents, if any,
incorporated or deemed to be incorporated by reference therein pursuant to the
Act, the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as
from time to time amended or supplemented pursuant to the Act or otherwise, are
hereinafter referred to as the "Registration Statement" and the "Prospectus",
respectively, except that if any revised prospectus shall be provided to the
Underwriters by the Company for use in connection with the offering of the
Securities which differs from the Prospectus on file at the Commission at the
time the Registration Statement became effective (whether or not such revised
prospectus is required to be filed by the Company pursuant to Rule 424(b) under
the Act ("Rule 424(b)") of 


                                       2
<PAGE>   3
the rules and regulations of the Commission promulgated under the Act (the
"Rules and Regulations"), the term "Prospectus" shall refer to such revised
prospectus from and after the time it is first provided to the Underwriters for
such use. All references in this Agreement to financial statements and schedules
and other information which is "contained," "included" or "stated" in the
Registration Statement or the Prospectus (and all other references of like
import) shall be deemed to mean and include all such financial statements and
schedules and other information which are or are deemed to be incorporated by
reference in the Registration Statement or the Prospectus, as the case may be;
and all references in this Agreement to amendments or supplements to the
Registration Statement or the Prospectus shall be deemed to mean and include the
filing of any documents under the Exchange Act after the date of this Agreement
which are or are deemed to be incorporated by reference in the Registration
Statement or the Prospectus, as the case may be.

      2.    Agreements to Sell and Purchase. The Company agrees to sell to the
Underwriters, severally and not jointly, and upon the basis of the
representations, warranties and agreements of the Company and WFS herein
contained and subject to all the terms and conditions of this Agreement, the

A-2 Notes, __.______% of the principal amount thereof; (iii) the Class A-3
Notes, __.______% of the principal amount thereof; (iv) the Class A-4 Notes,

of the principal amount thereof, in each case plus accrued interest at the
related Interest Rate or the Pass-Through Rate, as the case may be, from
September 1, 1998, to but not including the Closing Date.

      3.    Terms of Public Offering. The Company is advised by the
Representative that the Underwriters propose (i) to make a public offering of
the Securities as soon after the execution of this Agreement as in the judgment
of the Representative is advisable and (ii) initially to offer each Class of
Notes and the Certificates upon the terms set forth in the Prospectus.

      4.    Delivery and Payment. Delivery of the Securities shall be made at
the office of the Representative at 277 Park Avenue, New York, New York 10172 at
10:00 A.M., New York City time, on September __ , 1998 (such time and date are
referred to herein as the "Closing Date"). Payment for the Securities shall be
made at the offices of WFS Financial Inc, 23 Pasteur Road, Irvine, California
92718. The Closing Date and the location of the delivery of and payment for the
Securities may be varied by agreement between the Representative and the
Company.

      Each Class of Notes and the Certificates will be initially represented by
one or more certificates in definitive form registered in the name of Cede &
Co., the nominee of The Depository Trust Company ("DTC") (the "DTC
Certificates"). The certificates evidencing the DTC Certificates shall be made
available to the Representative for inspection not later than 10:00 A.M., New
York City time, on the business day immediately preceding the Closing Date. The
Securities shall be delivered to the Underwriters on the Closing Date for their
respective accounts against payment of the purchase price therefor by either (i)

(next day) funds to the order of the 


                                       3
<PAGE>   4
Company or (ii) wire transfer (same day funds), as the Representative and the
Company shall agree.

      Pursuant to Rule 15c6-1(d) under the Exchange Act, the parties hereto have
agreed that the Closing Date will be not later than September __, 1998.

      5.    Agreements of the Company. The Company agrees with the Underwriters:

      (a)   To transmit the Prospectus to the Commission pursuant to Rule 424(b)
by a means reasonably calculated to result in the timely filing of such
Prospectus with the Commission pursuant to Rule 424(b).

      (b)   To advise the Representative promptly and, if requested by the
Representative, to confirm such advice in writing, (i) when the Registration
Statement has become effective and when any post-effective amendment to it
becomes effective, (ii) of any request by the Commission for amendments to the
Registration Statement or amendments or supplements to the Prospectus or for
additional information, (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement or of the
suspension of qualification of any of the Securities for offering or sale in any
jurisdiction, or the initiation of any proceeding for either such purpose, and
(iv) of the happening of any event during the period referred to in paragraph
(e) below which, in the judgment of the Company, makes the Registration
Statement or the Prospectus contain an untrue statement of material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading. If at any time the Commission shall issue any
stop order suspending the effectiveness of the Registration Statement, the
Company will make every reasonable effort to obtain the withdrawal or lifting of
such order at the earliest possible time.

      (c)   To furnish to the Representative two signed copies of the
Registration Statement as first filed with the Commission and of each amendment
to it, including all exhibits, and to furnish to the Underwriters such number of
conformed copies of the Registration Statement as so filed and of each amendment
to it, without exhibits, as the Underwriters may reasonably request.

      (d)   Not to file any amendment or supplement to the Registration
Statement, whether before or after the time when it becomes effective, or to
make any amendment or supplement to the Prospectus of which the Representative
shall not previously have been advised or to which the Representative shall
reasonably object and to prepare and file with the Commission promptly upon the
request of the Representative, any amendment to the Registration Statement or
supplement to the Prospectus which may be necessary or advisable in connection
with the distribution of any of the Securities by the Underwriters, and to use
our best efforts to cause the same to become promptly effective.

      (e)   Promptly after the Registration Statement becomes effective, and
from time to time thereafter for such period as in the opinion of counsel to the
Underwriters a prospectus is required by law to be delivered in connection with
sales by the Underwriters or such dealers as the Representative shall specify,
to furnish to the Underwriters and each such dealer as many copies of the
Prospectus (and of each amendment or supplement to the Prospectus) as the
Underwriters or such dealer may reasonably request.

shall occur as a result of which, in the opinion of the Company or counsel to
the Underwriters it becomes necessary to amend or supplement the Prospectus in
order to make the statements therein, in the light of the circumstances when the
Prospectus is delivered to a purchaser, not misleading, or if it is necessary to
amend or supplement the Prospectus to comply with any law, forthwith to prepare
and file with the Commission an appropriate amendment or supplement to the
Prospectus so that the statements in the Prospectus, as so amended or
supplemented, will not, in the light of the circumstances when it is so
delivered, be misleading, or so that the Prospectus will comply with law, and to
furnish to the Underwriters and to such dealers as the Representative shall
specify, such number of copies thereof as the Underwriters or such dealers may

Underwriters and by dealers under the securities or Blue Sky laws of such
jurisdictions as the Underwriters may reasonably request, to continue such
qualification in effect so long as reasonably required for distribution of the
Securities and to file such consents to service of process or other documents as
may be necessary in order to effect such registration or qualification; provided
that the Company shall not be required to register or qualify as a foreign
corporation or to take any action which would subject it to service of process
in suits, other than as to matters and transactions relating to the offer and
sale of the Securities, in any jurisdiction where it is not now so subject.

      (h)   As soon as practicable, but not later than 16 months after the
"effective date" of the Registration Statement, to cause the Trust to make
generally available to holders of the Securities an earnings statement of the
Trust covering a 12 month period beginning not later than the first day of the
Trust's fiscal quarter next following the "effective date" of the Registration
Statement. Such statement shall satisfy the provisions of Section 11(a) of the
Act.

Owner Trustee, (ii) all documents of the Company or the Trust required to be
distributed to Securityholders or filed with the Commission pursuant to the
Exchange Act or any order of the Commission thereunder and (iii) such other
information concerning the Company, the Trust or WFS as the Underwriters may

<PAGE>   6
disbursements of counsel to the Underwriters relating to such reproducing and
delivery), (iv) the registration or qualification of the Securities for offer

in Section 5(g) hereof (including in each case the fees and disbursements of
counsel to the Underwriters relating to such registration or qualification and
memoranda relating thereto), (v) any filings and clearance with the National
Association of Securities Dealers, Inc. in connection with the public offering
of any of the Securities, (vi) any fees paid to rating agencies in connection

      (k)   To use its best efforts to do and perform all things required or
necessary to be done and performed under this Agreement by the Company prior to
the Closing Date and to satisfy all conditions precedent to the delivery of the
Securities. To the extent, if any, that the ratings provided with respect to the
Securities by any Rating Agency (as such term is defined in Section 8(m) hereof)
that initially rates the Securities is conditional upon the furnishing of
documents or the taking of any other actions by the Company, the Company shall
furnish such documents and take such other actions. 

      (l)   If this Agreement shall be terminated pursuant to any of the
provisions hereof (otherwise than by notice given by the Representative pursuant
to Section 9 hereof) or if for any reason the Company shall be unable to perform
its obligations hereunder, to reimburse the Underwriters for all of their
out-of-pocket expenses (including the fees and expenses of counsel to the
Underwriters) reasonably incurred by the Underwriters in connection herewith.

      (m)   To apply the net proceeds from the offering in the manner set forth

and the rules and regulations of the Commission under the Exchange Act (the
"Exchange Act Regulations")), will file all documents required to be filed with
the Commission pursuant to Section 13, 14 or 15 of the Exchange Act within the
time periods required by the Exchange Act and the Exchange Act Regulations. 

      6.    Representations and Warranties of the Company and WFS.

      (a)   The Company represents and warrants to the Underwriters that:

            (i)   The conditions to the use of a registration statement on Form

      the Prospectus and are duly and validly authorized and (i) when the
      Certificates have been executed, authenticated and delivered in accordance
      with the Trust Agreement and delivered to and paid for by the Underwriters
      as provided herein, will be entitled to the benefits and security afforded

      Company with the provisions hereof or thereof, will conflict with or
      result in a breach of any of the terms or provisions of, or constitute a
      default under, the articles of incorporation or bylaws of the Company or
      any indenture, mortgage, deed of trust or other agreement or instrument to
      which the Company is now a party or by which it is bound, or any order of
      any court or government agency or authority entered in any proceeding to
      which the Company was or is now a party or by which it is bound. 

            (vii) The Company has been duly incorporated and is validly existing
      in good standing under the laws of the State of California and is duly
      qualified to do business as a foreign corporation and is in good standing
      under the laws of each jurisdiction where the character of its properties
      or the nature of its activities makes such qualification necessary, except
      such jurisdictions, if any, in which the failure to be so qualified will
      not have a material adverse effect on either the business or properties of
      the Company; the Company holds all material licenses, certificates and
      permits from all governmental authorities necessary for the conduct of its
      business as described in the Prospectus; and the Company has the corporate
      power and authority to own its properties and conduct its business as
      described in the Prospectus. 

            (viii) Each of this Agreement and the Basic Documents to which the
      Company is a party, when executed and delivered as contemplated thereby,
      will have been duly authorized, executed and delivered by the Company and
      will constitute, when so executed and delivered, a legal, valid and
      binding instrument enforceable against the Company in accordance with its
      terms, subject to applicable bankruptcy, reorganization, insolvency,
      moratorium or other similar laws affecting creditors' rights generally,
      subject to general principles of equity (regardless of whether enforcement
      is sought in a proceeding in equity or at law) and, in the case of this
      Agreement and the Indemnification Agreement, except as rights to indemnity
      and contribution hereunder and thereunder may be limited by applicable
      law; each of the Basic Documents conforms to the description 


                                       8
<PAGE>   9
      thereof contained in the Prospectus; and the Indenture has been duly
      qualified under the 1939 Act. 

            (ix)  At the Closing Date, the Company will have good and marketable
      title to the Contracts listed in Schedule A to the Sale and Servicing
      Agreement, free and clear of any lien, mortgage, pledge, charge, security
      interest or other encumbrance (subject to the security interest afforded
      to Financial Security under the Insurance Agreement); and the Company's
      assignment and delivery of the Contract Documents to the Trust will vest
      in the Trust the full legal title purported to be conveyed thereby
      (subject to the security interest afforded to Financial Security under the
      Insurance Agreement). 

            (x)   The Trust's assignment of the Trust Estate to the Indenture
      Trustee pursuant to the Indenture will vest in the Indenture Trustee, for
      the benefit of the Noteholders, a first priority perfected security
      interest therein, subject to no prior lien, mortgage, pledge, charge,
      security interest or other encumbrance, except that such security interest
      will be subject to the security interest afforded to Financial Security
      under the Insurance Agreement. 

            (xi)  The representations and warranties made by the Company in the
      Sale and Servicing Agreement and in the Officers' Certificates of the
      Company delivered pursuant to the Basic Documents to which the Company is
      a party will be true and correct at the Closing Date. 

            (xii) Since June 30, 1998, there has been no material adverse change
      or development involving a prospective material adverse change in or
      affecting particularly the condition, financial or otherwise, of the
      Company, or the earnings, affairs or business prospects of the Company,
      whether or not arising in the ordinary course of business, except as set
      forth in or contemplated in the Prospectus. 

      (b)   WFS represents and warrants to the Underwriters that the
representations and warranties of the Company set forth in paragraph (a) above
are true and correct, and to the further effect that:

            (i)   WFS has been duly incorporated and is validly existing in good
      standing under the laws of the State of California and is duly qualified
      to do business as a foreign corporation and is in good standing under the
      laws of each jurisdiction where the character of its properties or the
      nature of its activities makes such qualification necessary, except such
      jurisdictions, if any, in which the failure to be so qualified will not
      have a material adverse effect on either the business or properties of
      WFS; WFS holds all material licenses, certificates and permits from all
      governmental authorities necessary for the conduct of its business as
      described in the Prospectus; and WFS has the corporate power and authority
      to own its properties and conduct its business as described in the
      Prospectus.

            (ii)  The execution and delivery by WFS of this Agreement and the
      Basic Documents to which it is a party are within the corporate power of
      WFS and have been duly authorized by all necessary action on the part of
      WFS; and neither the execution and 


                                       9
<PAGE>   10
      delivery by WFS of this Agreement and the Basic Documents to which it is a
      party, nor the consummation by WFS of the transactions herein and therein
      contemplated, nor compliance by WFS with the provisions hereof and
      thereof, will conflict with or result in a breach of any of the terms or
      provisions of, or constitute a default under, the articles of
      incorporation or bylaws of WFS or any indenture, mortgage, deed of trust
      or other agreement or instrument to which WFS is now a party or by which
      it is bound, or any order of any court or government agency or authority
      entered in any proceeding to which WFS was or is now a party or by which
      it is bound. 

            (iii) Each of this Agreement and each Basic Document to which WFS is
      a party has been duly authorized, executed and delivered by WFS and
      constitutes a valid and binding agreement of WFS, enforceable against WFS
      in accordance with its terms, subject to applicable bankruptcy,
      reorganization, insolvency, moratorium or other similar laws affecting
      creditors' rights generally, subject to general principles of equity
      (regardless of whether enforcement is sought in a proceeding in equity or
      at law) and, in the case of this Agreement and the Indemnification
      Agreement, except as rights to indemnity and contribution hereunder and
      thereunder may be limited by applicable law. 

            (iv)  The Contracts transferred to the Company from WFS on the
      Closing Date were free and clear of all liens (including tax liens),
      mortgages, pledges, charges, security interests and other encumbrances at
      the time of such transfer (subject to the security interest afforded to
      Financial Security under the Insurance Agreement). 

            (v)   WFS has the power and authority to own its properties, to
      conduct its business as described in the Prospectus and to enter into and
      perform its obligations under each of the Basic Documents to which it is a
      party. 

            (vi)  Since _____, 1998, there has been no material adverse change
      or development involving a prospective material adverse change in or
      affecting particularly the condition, financial or otherwise, of WFS, or
      the earnings, affairs or business prospects of WFS, whether or not arising
      in the ordinary course of business, except as set forth in or contemplated
      in the Prospectus. 

      7.    Indemnification.

      (a)   The Company and WFS jointly and severally agree to indemnify and
hold harmless each Underwriter and each person, if any, who controls each
Underwriter within the meaning of Section 15 of the Act, or Section 20 of the
Exchange Act, from and against any and all losses, claims, damages, liabilities
and judgments caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or the Prospectus (if used
within the period set forth in Section 5(e) hereof and as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) or any preliminary prospectus, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or judgments are caused by any such untrue
statement or omission or alleged untrue statement or omission based upon
information furnished 


                                       10
<PAGE>   11
in writing to the Company by the Underwriters through the Representative
expressly for use therein.

      (b)   In case any action shall be brought against any Underwriter or any
person controlling any Underwriter, based upon any preliminary prospectus, the
Registration Statement or the Prospectus or any amendment or supplement thereto
and with respect to which indemnity may be sought against the Company or WFS,
such Underwriter shall promptly notify the Company or WFS in writing and the
Company and WFS shall assume the defense thereof, including the employment of
counsel and payment of all fees and expenses. Such Underwriter or any such
controlling person shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the fees and expenses of such
counsel shall be at the expense of such Underwriter or such controlling person
unless (i) the employment of such counsel has been specifically authorized in
writing by the Company and WFS, (ii) the Company and WFS have failed to assume
the defense and employ counsel or (iii) the named parties to any such action
(including any impleaded parties) include both such Underwriter or such
controlling person and the Company or WFS, as the case may be, and such
Underwriter or such controlling person shall have been advised by such counsel
that there may be one or more legal defenses available to it which are different
from or additional to those available to the Company or WFS, as the case may be
(in which case the Company and WFS shall not have the right to assume the
defense of such action on behalf of such Underwriter or such controlling person;
it being understood, however, that the Company and WFS shall not, in connection
with any one such action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) for such
Underwriter and controlling persons, which firm shall be designated in writing
by such Underwriter and that all such fees and expenses shall be reimbursed as
they are incurred). The Company and WFS shall not be liable for any settlement
of any such action effected without the written consent of the Company and WFS
but, if settled with the written consent of the Company and WFS, the Company and
WFS agree that each person so consenting agrees to indemnify and hold harmless
each such Underwriter and any such controlling person from and against any loss
or liability by reason of such settlement. No indemnifying party shall, without
the prior written consent of the indemnified party, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding. 

      (c)   The Underwriters, severally but not jointly, agree to indemnify and
hold harmless the Company, WFS, their respective directors, their respective
officers who signed the Registration Statement and any person controlling the
Company and WFS to the same extent as the foregoing indemnity from the Company
and WFS to the Underwriters but only with reference to information relating to
the Underwriters furnished in writing by the Underwriters through the
Representative expressly for use in the Registration Statement, the Prospectus
or any preliminary prospectus. In case any action shall be brought against the
Company, any of its directors, any such officer or any such controlling person
based on the Registration Statement, the Prospectus or any preliminary
prospectus and in respect of which indemnity may be sought against any
Underwriter, such Underwriter shall have the rights and duties given to the
Company 


                                       11
<PAGE>   12
or WFS (except that if the Company or WFS shall have assumed the defense thereof
such Underwriter shall not be required to do so, but may employ separate counsel
therein and participate in the defense thereof but the fees and expenses of such
counsel shall be at the expense of such Underwriter), and the Company, its
directors, any such officers, any such controlling person and WFS shall have the
rights and duties given to the Underwriters by Section 7(b) hereof. 

      (d)   If the indemnification provided for in this Section is unavailable
to an indemnified party in respect of any losses, claims, damages, liabilities
or judgments referred to therein, then each indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages,
liabilities and judgments (i) in such proportion as is appropriate to reflect
the relative benefits received by the Company and WFS on the one hand and the
Underwriters on the other hand from the offering of the Securities or (ii) if
the allocation provided by clause (i) above is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company, WFS
and the Underwriters in connection with the statements or omissions which
resulted in such losses, claims, damages, liabilities or judgments, as well as
any other relevant equitable considerations. The relative benefits received by
the Company, WFS and the Underwriters shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Securities (before
deducting expenses) received by the Company and WFS and the total underwriting
discounts and commissions received by the Underwriters, bear to the total price
to the public of the Securities, in each case as set forth in the table on the
cover page of the Prospectus. The relative fault of the Company, WFS and the
Underwriters shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission to
state a material fact relates to information supplied by the Company, WFS or the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. 

      The Company, WFS and the Underwriters agree that it would not be just and
equitable if contribution pursuant to Section 7(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section, no Underwriter shall be required
to contribute any amount in excess of the amount by which the total price at
which the Securities underwritten by such Underwriter and distributed to the
public was offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

      8.    Conditions. The obligations of the Underwriters to purchase the
Securities under this Agreement are subject to the satisfaction of each of the
following conditions:


                                       12
<PAGE>   13
      (a)   All the representations and warranties of the Company and WFS
contained in this Agreement shall be true and correct on the Closing Date with
the same force and effect as if made on and as of the Closing Date.

      (b)   The Registration Statement shall have become effective not later
than 6:30 P.M., New York City time, on the date of this Agreement or at such
later date and time as the Representative may approve in writing, and at the
Closing Date no stop order suspending the effectiveness of the Registration
Statement shall have been issued and no proceedings for that purpose shall have
been commenced or shall be pending before or contemplated by the Commission. 

      (c)   Since June 30, 1998, there shall not have been any material adverse
change, or any development involving a prospective material adverse change, in
the condition, financial or otherwise, or in the earnings, affairs or business
prospects, whether or not arising in the ordinary course of business, of the
Company or WFS. On the Closing Date, the Representative shall have received (i)
a certificate dated the Closing Date, signed by the President or a Vice
President of the Company, confirming the matters set forth in paragraphs (a) (as
to the Company's representations and warranties only), (b) and (c) of this
Section (as to the Company only), and (ii) a certificate dated the Closing Date,
signed by the President or a Vice President of WFS, confirming the matters set
forth in paragraphs (a) and (c) of this Section. Such officers may in each
certificate rely upon the best of their information and belief as to proceedings
contemplated. 

      (d)   The Representative shall have received the opinion of Mitchell,
Silberberg & Knupp LLP, counsel for the Company, dated the Closing Date and
satisfactory to counsel to the Underwriters, to the effect that: 

            (i)   The Company has been duly incorporated and is validly existing
      and in good standing under the laws of the State of California, with
      corporate power and authority to own its properties, to conduct its
      business as described in the Prospectus and to enter into and perform its
      obligations under this Agreement and each of the Basic Documents to which
      it is a party, and is duly qualified and in good standing as a foreign
      corporation in each jurisdiction in which the location of its properties
      or the character of its operations makes such qualification necessary,
      except such jurisdictions, if any, in which the failure to be so qualified
      will not have a material adverse effect on either the business or
      properties of the Company.

            (ii)  The statements in the Prospectus set forth under the captions
      "Summary of Prospectus", "The Notes", "The Certificates", "The Contracts
      Pool" and "Certain Information Regarding the Securities", insofar as such
      statements purport to summarize certain provisions of the Notes, the
      Certificates or the Basic Documents, provide a fair summary of such
      provisions, and the statements in the Prospectus under the captions
      "Summary of Prospectus--Tax Status", "--ERISA Considerations", "Certain
      Legal Aspects of the Contracts", "Certain Federal Income Tax
      Consequences", "Certain California Income Tax Consequences" and "ERISA
      Considerations", to the extent such statements constitute matters of law
      or legal conclusions with respect thereto, have been prepared or reviewed
      by such counsel and are correct in all material respects. 


                                       13
<PAGE>   14
            (iii) For federal income tax purposes, the Notes will be considered
      debt, the Trust will not be an association taxable as a corporation and
      the Trust will not be a publicly traded partnership taxable as a
      corporation. The trust fund created by the Trust Agreement will not, for
      California income tax purposes, be classified as an association taxable as
      a corporation, and Certificateholders and Noteholders who are not
      residents of or otherwise subject to tax in California will not, solely by
      reason of their acquisition of an interest in any Class of Notes or the
      Certificates, be subject to California income, franchise, excise or
      similar taxes with respect to interest on any Class of Notes or the
      Certificates or with respect to any of the other Trust property. 

            (iv)  Each of this Agreement and the Indemnification Agreement has
      been duly authorized, executed and delivered by the Company. 

            (v)   Each Basic Document (other than the Indemnification Agreement)
      to which the Company is a party has been duly authorized, executed and
      delivered by the Company and, assuming the due authorization, execution
      and delivery by the other parties thereto, constitutes the valid, legal
      and binding obligation of the Company, enforceable against the Company, in
      accordance with its terms, except as enforceability thereof may be limited
      by bankruptcy, insolvency, reorganization or other laws now or hereafter
      in effect affecting the enforcement of creditors' rights generally, and
      except that no opinion is expressed as to the availability of remedies of
      specific performance, injunction or other forms of equitable relief, all
      of which may be subject to certain tests of equity jurisdiction, equitable
      defenses and the discretion of the court before which any proceeding
      therefor may be brought. 

            (vi)  Assuming the due authorization, execution and delivery of each
      Basic Document to which the Trust is a party by the Owner Trustee, on
      behalf of the Trust, and by each other party thereto (other than the
      Company) each such Basic Document constitutes the valid, legal and binding
      obligation of the Trust enforceable against the Trust in accordance with
      its terms, except as enforceability thereof may be limited by bankruptcy,
      insolvency, reorganization or other laws now or hereafter in effect
      affecting the enforcement of creditors' rights generally, and except that
      no opinion is expressed as to the availability of remedies of specific
      performance, injunction or other forms of equitable relief, all of which
      may be subject to certain tests of equity jurisdiction, equitable defenses
      and the discretion of the court before which any proceeding therefor may
      be brought. 

            (vii) The Certificates, when executed and authenticated in
      accordance with the Trust Agreement and delivered and paid for pursuant to
      this Agreement, will be validly issued and outstanding and entitled to the
      benefits of the Trust Agreement. 

            (viii) The Notes, when executed and authenticated in accordance with
      the Indenture and delivered and paid for pursuant to this Agreement, will
      be entitled to the benefits of the Indenture and will constitute legal,
      valid and binding obligations of the Trust, entitled to the benefits of
      the Indenture, and enforceable in accordance with their terms and the
      terms of the Indenture (subject to the security interest afforded to
      Financial Security under the Insurance Agreement), subject, with respect
      to each of the Indenture 


                                       14
<PAGE>   15
      and the Notes, to applicable bankruptcy, reorganization, insolvency,
      moratorium or other similar laws affecting creditors' rights generally,
      and except that no opinion is expressed as to the availability of remedies
      of specific performance, injunction or other forms of equitable relief,
      all of which may be subject to certain tests of equity jurisdiction,
      equitable defenses and the discretion of the court before which any
      proceeding therefor may be brought. 

            (ix)  As to each security interest in a Financed Vehicle created by
      a Contract, no filing or other action is necessary to perfect or continue
      the perfected status of such security interest as against creditors of or
      transferees from the obligor under such Contract, so long as such Financed
      Vehicle is not removed from the State of California for a period longer
      than four months, or before the end of such four-month period, WFS
      perfects such security interest under applicable law; provided that (A) no
      opinion is rendered as to a security interest in a Financed Vehicle as to
      which neither a properly endorsed certificate of title naming WFS or an
      affiliate or predecessor of WFS as legal owner nor an application for an
      original registration together with an application for registration of WFS
      or an affiliate or predecessor of WFS as legal owner, has been deposited
      with the California Department of Motor Vehicles, and (B) no opinion is
      given as to the enforceability of the security interest in a Financed
      Vehicle as against a subsequent owner of a Financed Vehicle or a holder or
      assignee of a certificate of title relating to such Financed Vehicle
      through fraudulent or negligent transfer of such certificate of title. 

            (x)   The Sale and Servicing Agreement, together with the filing
      referred to in this subsection, creates and perfects the ownership
      interest of the Trust in the Contracts which is a valid first priority
      ownership interest (subject to the security interest afforded to Financial
      Security under the Insurance Agreement); a financing statement with
      respect to the Contracts has been filed with the Secretary of State of the
      State of California pursuant to the California Uniform Commercial Code, as
      amended, and with the Secretary of State of the State of Delaware,
      pursuant to the Delaware Uniform Commercial Code, as amended; and no other
      filings in any jurisdiction or any other actions are necessary to perfect
      the ownership interest of the Trustee in the Contracts against any third
      parties. 

            (xi)  The Indenture constitutes a grant by the Trust to the
      Indenture Trustee of a valid security interest in the Contracts, the
      security interests in the Financed Vehicles securing the Contracts and the
      proceeds of each of the foregoing (subject to the security interest
      afforded to Financial Security under the Insurance Agreement), which
      security interest has been perfected by the filing of financing statements
      with the Secretary of State of the State of California and the Secretary
      of State of the State of Delaware, each as pursuant to the Uniform
      Commercial Code as in effect in such state. No filing or other action,
      other than the filing of the financing statements referred to above, is
      necessary to perfect and maintain the interest or the security interest of
      the Indenture Trustee in the Contracts, the security interests in the
      Financed Vehicles securing the Contracts and the proceeds of each of the
      foregoing against third parties (subject to the security interest afforded
      to Financial Security under the Insurance Agreement). 


                                       15
<PAGE>   16
            (xii) The Company's assignment and delivery of the Contracts to the
      Trust will vest in the Trust all of the Company's right, title and
      interest therein, subject to no prior lien, mortgage, security interest,
      pledge, adverse claim, charge or other encumbrance, except that such
      security interest will be subject to the security interest afforded to
      Financial Security under the Insurance Agreement. 

            (xiii) The Trust's assignment of the Contracts to the Indenture
      Trustee pursuant to the Indenture will vest in the Indenture Trustee, for
      the benefit of the Noteholders, a first priority perfected security
      interest therein, subject to no prior lien, mortgage, security interest,
      pledge, adverse claim, charge or other encumbrance. 

            (xiv) The Registration Statement has become effective under the Act
      and the Prospectus has been filed with the Commission, pursuant to Rule
      424(b) and, to the best of the knowledge of such counsel, no stop order
      suspending the effectiveness of the Registration Statement has been issued
      and no proceedings for that purpose have been instituted or are pending or
      contemplated. 

            (xv)  No order, consent or other authorization or approval of any
      court, public board or governmental body is legally required for the
      performance by the Company of its obligations under this Agreement or any
      of the Basic Documents to which the Company is a party, except such as
      have been obtained under the Act, such as may be required under the Blue
      Sky laws of any jurisdiction in connection with the purchase and
      distribution of the Securities by the Underwriters, such as have been
      obtained from the Office of Thrift Supervision and such other approvals
      (specified in such opinion) as have been obtained. 

            (xvi) Neither the consummation of the transactions contemplated in
      this Agreement or any Basic Document to which the Company is a party, nor
      the fulfillment of the terms hereof or thereof will conflict with, result
      in a breach of, or constitute a default under the articles of
      incorporation or bylaws of the Company or the terms of (A) any indenture
      or other agreement or instrument known to such counsel and to which the
      Company or any of its subsidiaries is a party or is bound, or (B) any
      judgment, order or decree known to such counsel to be applicable to the
      Company or any of its subsidiaries of any court, regulatory body,
      administrative agency, governmental body or arbitrator having jurisdiction
      over the Company or any of its subsidiaries, except, in the case of
      clauses (A) and (B), for defaults, breaches or violations that do not, in
      the aggregate, have a material adverse affect on the Company. 

            (xvii) To the best knowledge of such counsel, there is no legal or
      governmental proceeding pending or threatened to which the Trust or the
      Company is, or is threatened to be, a party or of which the business or
      property of the Trust or the Company is, or is threatened to be, the
      subject that is material to the business or financial condition of the
      Trust or the Company and is not disclosed in the Prospectus. 

            (xviii) There is no contract or other document known to such counsel
      of a character required to be described in the Prospectus or to be filed
      as an exhibit to the Registration Statement that is not described or filed
      as required. 


                                       16
<PAGE>   17
            (xix) Neither the Trust nor the Company is an "investment company"
      and neither is "controlled" by an "investment company", as such terms are
      defined in the Investment Company Act of 1940, as amended. 

            (xx)  The Company has obtained all material licenses, permits and
      other governmental authorizations which are necessary to the conduct of
      its business; such licenses, permits and other governmental authorizations
      are in full force and effect, and the Company is in all material respects
      complying therewith; and the Company is otherwise in compliance with all
      laws, rules, regulations and statutes of any jurisdiction to which it is
      subject, except where non-compliance would not have a material adverse
      effect on the Company. 

            (xxi) Except as to the financial statements and other financial and
      statistical data included therein, as to which such counsel need not
      express any opinion, such counsel (A) is of the opinion the Registration
      Statement and the Prospectus and any supplements or amendments thereto
      (except for the financial statements and other financial or statistical
      data included therein and the Form T-1) comply as to form in all material
      respects with the Act and the 1939 Act and (B) believes that the
      Registration Statement (except for the financial statements and other
      financial or statistical data included therein, the information regarding
      Financial Security included therein and the Form T-1), at the time the
      Registration Statement became effective, did not contain any untrue
      statement of a material fact or omit to state a material fact required to
      be stated therein or necessary to make the statements therein not
      misleading and the Prospectus (except for the financial statements and
      other financial or statistical data included therein and the information
      regarding Financial Security included therein) at the date hereof and at
      the Closing Date did not and does not contain any untrue statement of a
      material fact and did not and does not omit to state a material fact
      necessary in order to make the statements therein, in the light of the
      circumstances under which they were made, not misleading. 

            (xxii) The documents incorporated or deemed to be incorporated by
      reference in the Prospectus (other than the financial statements,
      supporting schedules and other financial data therein, as to which no
      opinion need be rendered), when they were filed with the Commission,
      complied as to form in all material respects with the applicable
      requirements of the Exchange Act and the Exchange Act Regulations. 

            (xxiii) The Indenture has been duly qualified under the 1939 Act and
      the Trust Agreement is not required to be qualified under the 1939 Act.

      (e)   The Representative shall have received the opinion of Harriet Burns
Feller, Esq., General Counsel of WFS, General Counsel of Western Financial Bank
(the "Bank") and General Counsel of WII, dated the Closing Date and satisfactory
to counsel to the Underwriters, to the effect that:

            (i)   Each of WFS and WII has been duly incorporated and is validly
      existing and in good standing under the laws of the State of California,
      with corporate power and authority to own its properties, to conduct its
      business as described in the Prospectus and to enter into and perform its
      obligations under this Agreement and each of the Basic 


                                       17
<PAGE>   18
      Documents to which it is a party, and is duly qualified and in good
      standing as a foreign corporation in each jurisdiction in which the
      location of its properties or the character of its operations makes such
      qualification necessary, except such jurisdictions, if any, in which the
      failure to be so qualified will not have a material adverse effect on
      either the business or properties of WFS or WII, as the case may be.

            (ii)  This Agreement has been duly authorized, executed and
      delivered by WFS.

            (iii) Each Basic Document to which each of WFS or WII is a party has
      been duly authorized, executed and delivered by WFS or WII, as the case
      may be, and each Basic Document other than the Indemnification Agreement
      constitutes a legal, valid and binding agreement of WFS or WII, as the
      case may be, enforceable against WFS or WII, as the case may be, in
      accordance with its terms, except as enforceability thereof may be subject
      to or limited by bankruptcy, insolvency, reorganization or other laws,
      provisions or principles now or hereafter in effect affecting the
      enforcement of creditors' rights generally except that no opinion is
      expressed as to the availability of remedies of specific performance,
      injunction or other forms of equitable relief, all of which may be subject
      to certain tests of equity jurisdiction, equitable defenses and the
      discretion of the court before which any proceeding therefor may be
      brought. 

            (iv)  No consent, approval, authorization or order of any court or
      governmental agency or body is required for the performance by each of WFS
      or WII of its respective obligations under this Agreement and any of the
      Basic Documents to which it is a party, except such as have been obtained.

            (v)   Neither the consummation of any of the transactions
      contemplated by this Agreement and each of the Basic Documents to which
      WFS or WII is a party nor the fulfillment of the terms hereof or thereof
      will conflict with, result in a breach of, or constitute a default under,
      the respective articles of incorporation or bylaws of WFS or WII, as the
      case may be, or the terms of (A) any indenture or other agreement or
      instrument known to such counsel and to which WFS or WII, as the case may
      be, or any of its subsidiaries is a party or is bound or (B) any judgment,
      order or decree known to such counsel to be applicable to WFS or any of
      its subsidiaries or WII, as the case may be, of any court, regulatory
      body, administrative agency, governmental body or arbitrator having
      jurisdiction over WFS or any of its subsidiaries or WII, as the case may
      be, except, in the case of clauses (A) and (B), for defaults, breaches or
      violations that do not, in the aggregate, have an adverse material effect
      on WFS or WII, as the case may be. 

            (vi)  To the best knowledge of such counsel, there is no legal or
      governmental proceeding pending or threatened to which WFS or WII, as the
      case may be, is, or is threatened to be, a party or of which its business
      or property is, or is threatened to be, the subject that would have a
      material adverse effect on the ability of WFS or WII, as the case may be,
      to perform its obligations under any of the Basic Documents to which it is
      a party. 

            (vii) Each of WFS and WII has obtained all material licenses,
      permits and other governmental authorizations which are necessary to the
      conduct of its business; such 


                                       18
<PAGE>   19
      licenses, permits and other governmental authorizations are in full force
      and effect, and each of WFS and WII is in all material respects complying
      therewith; and each of WFS and WII is otherwise in compliance with all
      laws, rules, regulations and statutes of any jurisdiction to which it is
      subject, except where non-compliance would not have a material adverse
      effect on WFS or WII, as the case may be, or, in the case of the
      Contracts, would not cause the Contracts to be unenforceable. 

            (viii) The Bank has been duly organized and is validly existing and
      in good standing as a Federal association pursuant to the laws of the
      United States of America, with the authority within its charter to own its
      properties, to conduct its business as described in the Prospectus and to
      enter into and perform its obligations under the Reinvestment Contract
      dated as of September 1, 1998, between the Bank and the Indenture Trustee,
      and the Sale and Assignment dated as of September 1, 1998, from the Bank
      to WFS of the Contracts (collectively, the "Bank Agreements"). 

            (ix)  Each of the Bank Agreements has been duly authorized, executed
      and delivered by the Bank and constitutes a legal, valid and binding
      instrument enforceable against the Bank in accordance with its terms,
      except as enforceability thereof may be limited by bankruptcy, insolvency,
      reorganization or other laws, provisions or principles now or hereafter in
      effect affecting the enforcement of creditors' rights generally or the
      rights of creditors of savings banks the accounts of which are insured by
      the Federal Deposit Insurance Corporation and except that no opinion is
      expressed as to the availability of remedies of specific performance,
      injunction or other forms of equitable relief, all of which may be subject
      to certain tests of equity jurisdiction, equitable defenses and the
      discretion of the court before which any proceeding therefor may be
      brought. 

            (x)   No consent, approval, authorization or order of any court or
      governmental agency or body is required for the consummation of the
      transactions contemplated by the Bank Agreements except such as have been
      obtained under the Act and such as have been obtained from the Office of
      Thrift Supervision. 

            (xi)  Neither the consummation of any of the transactions
      contemplated by the Bank Agreements, nor the fulfillment of the terms
      thereof, will conflict with, result in a breach of, or constitute a
      default under the Charter or bylaws of the Bank or (i) the terms of any
      indenture or other agreement or instrument known to such counsel to be
      applicable to the Bank or any of its subsidiaries or (ii) any judgment,
      order or decree known to such counsel to be applicable to the Bank or any
      of its subsidiaries of any court, regulatory body, administrative agency,
      governmental body or arbitrator having jurisdiction over the Bank or any
      of its subsidiaries, except in the case of clauses (i) and (ii), for
      defaults, breaches or violations that do not in the aggregate, have a
      material adverse effect on the Bank. 

            (xii) The Bank is in compliance with all applicable state and
      federal laws regarding its continued operation, including those pertaining
      to the origination of the Contracts, other than those laws the Bank's
      non-compliance with which would not materially affect its ability to
      perform its obligations under the Bank Agreements or, in 


                                       19
<PAGE>   20
      the case of the origination of the Contracts, would not cause the
      Contracts to be unenforceable. 

      (f)   The Representative shall have received from Mitchell, Silberberg &
Knupp LLP, counsel for the Company, a letter dated the Closing Date to the
effect that the Underwriters may rely upon each opinion rendered by such counsel
to either Standard & Poor's or Moody's Investors Service, Inc. in connection
with the rating of any of the Securities, as if each such opinion were addressed
to the Underwriters.

      (g)   The Representative shall have received the opinion of Bruce E.
Stern, Esq., General Counsel for Financial Security, dated the Closing Date and
satisfactory to counsel to the Underwriters. 

      (h)   The Representative shall have received the opinion addressed to the
Underwriters and to WFS from Richards, Layton & Finger, counsel to the Owner
Trustee, dated the Closing Date and satisfactory in form and substance to
counsel to the Underwriters and to counsel to the Company, to the effect that:

            (i)   The Owner Trustee has been duly incorporated and is validly
      existing as a banking corporation in good standing under the laws of the
      State of Delaware.

            (ii)  The Owner Trustee has full corporate trustee power and
      authority to enter into and perform its obligations under the Trust
      Agreement and, on behalf of the Trust, under the Indenture, the Sale and
      Servicing Agreement and the Administration Agreement. 

            (iii) The execution and delivery of the Trust Agreement and, on
      behalf of the Trust, of the Indenture, the Sale and Servicing Agreement,
      the Administration Agreement, the Certificates and the Notes and the
      performance by the Owner Trustee of its obligations under the Trust
      Agreement, the Indenture, the Sale and Servicing Agreement and the
      Administration Agreement have been duly authorized by all necessary
      corporate action of the Owner Trustee and each has been duly executed and
      delivered by the Owner Trustee. 

            (iv)  The Trust Agreement, the Sale and Servicing Agreement, the
      Indenture and the Administration Agreement constitute valid and binding
      agreements of the Owner Trustee, enforceable against the Owner Trustee in
      accordance with their terms, subject, as to enforcement of remedies, (A)
      to applicable bankruptcy, insolvency and reorganization, generally, and
      (B) to general principles of equity (regardless of whether such
      enforceability is considered in a proceeding in equity or at law). 

            (v)   The execution and delivery by the Owner Trustee of the Trust
      Agreement and, on behalf of the Trustee, of the Indenture, the Sale and
      Servicing Agreement and the Administration Agreement do not require any
      consent, approval or authorization of, or any registration or filing with,
      any Delaware or United States Federal governmental authority having
      jurisdiction over the trust power of the Owner Trustee, other than those
      consents, approvals or authorizations as have been obtained and the filing
      of the Certificate of Trust with the Secretary of State of the State of
      Delaware. 


                                       20
<PAGE>   21
            (vi)  The Notes have been duly authorized, executed and issued by
      the Trust. 

            (vii) The Certificates have been duly authorized, executed and
      issued by the Trust. 

            (viii) The execution and delivery by the Owner Trustee of the Trust
      Agreement and, on behalf of the Trust, the Sale and Servicing Agreement,
      the Indenture and the Administration Agreement, and the performance by the
      Owner Trustee of its obligations thereunder do not conflict with, result
      in a breach or violation of or constitute a default under, the Articles of
      Association or By-laws of the Owner Trustee. 

      (i)   The Representative shall have received an opinion addressed to the
Underwriters and to WFS, dated as of the Closing Date, of Richards, Layton &
Finger, special Delaware counsel to the Trust, in form and substance
satisfactory to counsel to the Underwriters and counsel to WFS, to the effect
that:

            (i)   The Trust has been duly formed and is validly existing as a
      business trust pursuant to the laws of the State of Delaware, 12 Del. C.
      Section 3801, et seq.

            (ii)  The Trust Agreement authorizes the Trust to execute and
      deliver the Indenture, the Sale and Servicing Agreement and the
      Administration Agreement, to issue the Certificates and Notes and to grant
      the trust estate to the Indenture Trustee as security for the Notes. 

            (iii) Assuming that the Certificates have been duly authorized,
      executed and issued by the Trust, when delivered to the Underwriter and
      paid for by the Underwriter pursuant to this Agreement, the Certificates
      have been validly issued and are entitled to the benefits of the Trust
      Agreement. 

            (iv)  Except for the timely filing in the future of continuation
      statements with respect to the financing statements, no other filing is
      required in the State of Delaware in order to make effective the lien of
      the Indenture. Insofar as the Delaware Uniform Commercial Code, 6 Del. C.
      Section 9-101 et seq. (the "UCC"), applies (without regard to conflict of
      laws principles) and, assuming that the security interests in that portion
      of the trust estate that consists of general intangibles, accounts or
      chattel paper, as defined under the UCC, have been duly created and have
      attached, the Indenture Trustee has a perfected security interest in such
      general intangibles, accounts or chattel paper and, assuming that the UCC
      search accurately lists all the financing statements filed naming the
      Trust as debtor and describing any portion of the trust estate consisting
      of such general intangibles, accounts or chattel paper, the security
      interest of the Indenture Trustee will be prior to the security interest
      of all other creditors, except that such security interest will be subject
      to the security interest afforded to Financial Security under the
      Insurance Agreement, and excluding purchase money security interests under
      Section 9-312(4) of the UCC, and temporarily perfected security interests
      pursuant to Section 9-306(3) of the UCC (as to the priority of temporarily
      unrecorded security interests in proceeds), subject to customary and usual
      exceptions. 


                                       21
<PAGE>   22
            (v)   No creditor of the Seller or any Certificateholder shall have
      any right to obtain possession or, or otherwise legal or equitable
      remedies with respect to, the property of the Trust. 

            (vi)  Assuming that the Sale and Servicing Agreement conveys good
      title to the Trust Property referred to therein to the Trust as a true
      sale and not as a security arrangement, the Trust rather than the Seller
      is the owner of the Trust Property. 

      (j)   The Representative shall have received an opinion addressed to the
Underwriters and to WFS from White & Case, counsel to the Indenture Trustee,
dated the Closing Date and satisfactory in form and substance to counsel to the
Underwriters and to special counsel to WFS to the effect that:

            (i)   The Indenture Trustee has been duly incorporated and is
      validly existing as a banking corporation under the laws of the State of
      New York.

            (ii)  The Indenture Trustee, at the time of its execution and
      delivery of the Indenture, had full power and authority to execute and
      deliver the Indenture and has full power and authority to perform its
      obligations thereunder. 

            (iii) The Indenture has been duly and validly authorized, executed
      and delivered by the Indenture Trustee and, assuming due authorization,
      execution and delivery thereof by the Trustee, constitutes the valid and
      binding obligation of the Indenture Trustee enforceable against the
      Indenture Trustee in accordance with its terms, except as enforcement
      thereof may be limited by bankruptcy, insolvency or other laws relating to
      or affecting creditors' rights or by general principles of equity. 

            (iv)  To the best of such counsel's knowledge, there are no actions,
      proceedings or investigations pending or threatened against or affecting
      the Indenture Trustee before or by any court, arbitrator, administrative
      agency or other governmental authority which, if adversely decided, would
      materially and adversely affect the ability of the Indenture Trustee to
      carry out the transactions contemplated in the Indenture. 

            (v)   No consent, approval or authorization of, or registration,
      declaration or filing with, any court or governmental agency or body of
      the United States of America or any state thereof was or is required for
      the execution, delivery or performance by the Indenture Trustee of the
      Indenture. 

      (k)   The Representative shall have received the opinion of Brown & Wood
LLP, counsel to the Underwriters, dated the Closing Date, with respect to the
issuance and sale of the Notes, the Registration Statement, the Prospectus and
other related matters as the Representative may reasonably require, and the
Company and WFS shall have furnished to counsel to the Underwriters such
documents as they may reasonably request for the purpose of enabling them to
pass upon such matters.

      (l)   The Representative shall have received letters in form and substance
satisfactory to the Representative, addressed to the Underwriters and dated the
date hereof and the Closing 


                                       22
<PAGE>   23
Date, from Ernst & Young LLP, independent public accountants for the Company,
substantially in the forms heretofore approved by the Representative. 

      (m)   At the Closing Date each Class of Notes and the Certificates shall
have been rated in the highest category by at least one nationally recognized
rating agency without regard to the benefit afforded the Notes under the Note
Policy and such ratings shall be in full force and effect and subsequent to the
execution and delivery of this Agreement and prior to the Closing Date, there
shall not have been any downgrading, nor any notice given by any "nationally
recognized statistical rating organization," as such term is defined for
purposes of Rule 436(g)(2) under the Act (a "Rating Agency"), to the public or
the Company of any intended or potential downgrading or of a possible change
that does not indicate the direction of the possible change, in the rating
accorded any of the Company's securities by any Rating Agency. 

      (n)   The Representative shall have received the Indemnification Agreement
executed by all parties thereto. 

      9.    Effective Date of Agreement and Termination. This Agreement shall
become effective upon the later of (i) execution of this Agreement and (ii)
receipt of notification of the effectiveness of the Registration Statement by
the Company or the Representative.

      This Agreement may be terminated at any time prior to the Closing Date by
the Representative by written notice to the Company if any of the following has
occurred: (i) since the respective dates as of which information is given in the
Registration Statement and the Prospectus, any adverse change or development
involving a prospective adverse change in or affecting particularly the
condition, financial or otherwise, of the Company or WFS or the earnings,
affairs or business prospects of the Company or WFS, whether or not arising in
the ordinary course of business, which would, in the reasonable judgment of the
Representative, make the offering or delivery of any Class of Notes or the
Certificates impracticable, (ii) any outbreak of hostilities or other national
or international calamity or crisis or material change in economic conditions,
if the effect of such outbreak, calamity, crisis or change on the financial
markets of the United States or elsewhere would, in the reasonable judgment of
the Representative, make the offering or delivery of any Class of Notes or the
Certificates impracticable, (iii) suspension of trading in securities on the New
York Stock Exchange or the American Stock Exchange or limitation on prices
(other than limitations on hours or numbers of days of trading) for securities
on either such Exchange, (iv) the enactment, publication, decree or other
promulgation of any federal or state statute, regulation, rule or order of any
court or other governmental authority which in the reasonable opinion of the
Representative materially and adversely affects, or will materially and
adversely affect, the business or operations of the Company, (v) declaration of
a banking moratorium by either federal or New York State authorities or (vi) the
taking of any action by any federal, state or local government or agency in
respect of its monetary or fiscal affairs which in the reasonable opinion the
Representative has a material adverse effect on the financial markets in the
United States.

      10.   Miscellaneous. Notices given pursuant to any provision of this
Agreement shall be addressed as follows: (i) if to the Company, to Harriet Burns
Feller, Esq. at her office at 23 Pasteur Road, Irvine, California 92618, (ii) if

      The respective indemnities, contribution agreements, representations,
warranties and other statements of WFS, the Company, their respective officers
and directors and of the Underwriters set forth in or made pursuant to this
Agreement shall remain operative and in full force and effect, and will survive
delivery of and payment for the Securities, regardless of (i) any investigation,
or statement as to the results thereof, made by or on behalf of the Underwriters
or by or on behalf of the Company, its officers or directors or any controlling
person of the Company or WFS, (ii) acceptance of the Securities and payment for
them hereunder and (iii) termination of this Agreement.

      If this Agreement shall be terminated by the Representative because of any

                    Registration Statement on Form S-3, File Number 333-59293
                    ---------------------------------------------------------

Dear Ladies and Gentlemen:

                  We are counsel for WFS Financial Auto Loans, Inc. (the
"Company") in connection with the proposed offering of $700,000,000 principal
amount of Auto Receivable Backed Securities consisting of four classes of Notes
and one class of Certificates (the Notes and Certificates together, the
"Securities") as identified in the above referenced Registration Statement to be
issued by the WFS Financial 1998-C Owner Trust (the "Trust") originated by the
Company. The Notes are obligations of the Trust secured by the assets of the
Trust and the Certificates represent undivided interests in the assets of the
Trust. The Notes are to be issued pursuant to an indenture between the Trust and
Bankers Trust Company as the Trustee (the "Indenture"). The Certificates are to
be issued pursuant to a trust agreement (the "Agreement") among the Company, WFS
Investments, Inc., Financial Security Assurance Inc. and Chase Manhattan Bank
Delaware, as Owner Trustee. The Securities are to be registered for sale
pursuant to the accompanying Form S-3 Registration Statement.

                  In our capacity as counsel for the Company and for purposes of
this opinion, we have made those examinations and investigations of the legal
and factual matters we deemed advisable, and have examined the originals, or
copies identified to our satisfaction as being true copies of the originals, of
the certificates, documents, corporate records, and other instruments which we,
in our judgment, have considered necessary or appropriate to enable us to render
the opinion expressed below. We have relied, without independent investigation
or confirmation, upon certificates

provided by public  officials and officers of the Company as to certain  factual
matters. In the course of our examinations and  investigations,  we have assumed
the genuineness of all signatures on original  documents,  and the due execution
and  delivery of all  documents  requiring  due  execution  and delivery for the
effectiveness thereof.

                  Based upon and subject to the foregoing and in reliance
thereon, and subject to the assumptions, exceptions and qualifications set forth
herein, it is our opinion that:

                  The Notes, when executed and authenticated as specified in the
Indenture and delivered to and paid for by Donaldson, Lufkin & Jenrette
Securities Corporation, BancAmerica Securities, Inc. and Morgan Stanley & Co.
Incorporated (together, the "Underwriters") pursuant to the underwriting
agreement among the Underwriters, the Company and WFS Financial Inc (the
"Underwriting Agreement"), will constitute legal, valid and binding obligations
of the Trust, entitled to the benefits of the Indenture, and enforceable in
accordance with their terms, except as enforceability thereof may be limited by
bankruptcy, insolvency, reorganization or other laws, provisions or principles
now or hereafter in effect affecting the enforcement of creditors' rights
generally and except that no opinion is expressed as to the availability of
remedies of specific performance, injunction or other forms of equitable relief,
all of which may be subject to certain tests of equity jurisdiction, equitable
defenses and the discretion of the court before which any such proceeding may be
brought.

                  The Certificates have been duly authorized, and when executed
and authenticated as specified in the Agreement and delivered to and paid for by
the Underwriters pursuant to the Underwriting Agreement, will be legally issued,
fully paid and non-assessable, and will be binding obligations of the Trust and
entitled to the benefits of the Agreement.

                  We consent to the filing of this opinion with, and to the
reference to our firm under the caption "Legal Matters" in the Registration
Statement. In giving our consent, we do not hereby admit that we come within the
category of persons whose consent is required under Section 7 of the Securities
Act of 1933, as amended, or the rules and regulations thereunder. This opinion
is given as of the date hereof and we assume no obligation to advise you of
changes that may hereafter be brought to our attention.


                               Very truly yours,

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

Dear Ladies and Gentlemen:

                  We have acted as legal counsel for WFS Financial Auto Loans,
Inc., a California corporation (the "Company"), in connection with the
preparation of the Company's Registration Statement, as amended, on Form S-3
under the Securities Act of 1933, as amended (the "Registration Statement"),
filed with the Securities and Exchange Commission relating to the issuance of
certain certificates (the "Certificates") representing undivided interests in
the WFS Financial 1998-C Owner Trust (the "Trust") and certain notes (the
"Notes" and together with the Certificates the "Securities") secured by the
assets of the Trust.

                  In rendering the opinion set forth below, we have examined the
Registration Statement dated as filed on November , 1998 (the "Form S-3") and
such exhibits to the Form S-3 as we have considered necessary or appropriate for
the purposes of this opinion. In rendering this opinion, we have assumed that a
final version of the Form S-3 will become the effective Registration Statement
of the Company without material change in the facts stated, and that the
issuance of the Securities will be duly authorized by all necessary action and
duly executed substantially in the manner described in the Form S-3. In
rendering this opinion, we have relied upon certain representations regarding
the underlying facts set forth in the Form S-3, including the existence, nature
and sufficiency of the installment contracts which shall be held as assets of
the Trust, as set forth in certain certificates provided by officers of the
Company and by officers of Western Financial Bank and WFS Financial Inc. The
opinion set forth herein is expressly based upon such assumptions and
representations and upon the accuracy of those facts so assumed or represented.
With respect to the underlying facts, we have made only such factual inquiries
as we have deemed appropriate and have not independently verified any facts.

                                    ARTICLE I

                            MEETINGS OF STOCKHOLDERS


SECTION 1. The annual meeting of the stockholders of this Company shall be held

the third Tuesday in January of each year, for the election of directors and
such other business as may properly come before said meeting.

SECTION 2. Special meetings of stockholders other than those regulated by
statute may be called at any time by a majority of the directors. It shall be
the duty of the Chairman of the Board, the Chief Executive Officer or the
President to call such meetings whenever requested in writing to do so by
stockholders owning a majority of the capital stock.

SECTION 3. At all meetings of stockholders, there shall be present, either in
person or by proxy, stockholders owning a majority of the capital stock of the
Company, in order to constitute a quorum, except at special elections of
directors, as provided by law, but less than a quorum shall have power to

SECTION 4. The Chairman of the Board or, in his absence, the Chief Executive

not less than ten nor more than twenty-five, as may from time to time be fixed
by resolution adopted by a majority of the directors then in office, or by the
stockholders. In the event of any increase in the number of directors,
additional directors may be elected within the limitations so fixed, either by
the stockholders or within the limitations imposed by law, by a majority of
directors then in office. One-third of the number of directors, as fixed from

All directors hereafter elected shall hold office until the next annual meeting
of the stockholders and until their successors are elected and have qualified.
No person who shall have attained age 72 shall be eligible to be elected or
re-elected a director. Such director may, however, remain a director of the
Company until the next annual meeting of the stockholders of Bankers Trust New
York Corporation (the Company's parent) so that such director's retirement will

then in office, and the directors so elected shall hold office for the balance
of the unexpired term.

SECTION 3. The Chairman of the Board shall preside at meetings of the Board of
Directors. In his absence, the Chief Executive Officer or, in his absence, such
other director as the Board of Directors from time to time may designate shall

SECTION 4. The Board of Directors may adopt such Rules and Regulations for the
conduct of its meetings and the management of the affairs of the Company as it

these By-Laws, and all officers and employees shall strictly adhere to, and be
bound by, such Rules and Regulations.

SECTION 5. Regular meetings of the Board of Directors shall be held from time to
time on the third Tuesday of the month. If the day appointed for holding such

SECTION 1. There shall be an Executive Committee of the Board consisting of not
less than five directors who shall be appointed annually by the Board of
Directors. The Chairman of the Board shall preside at meetings of the Executive
Committee. In his absence, the Chief Executive Officer or, in his absence, such
other member of the Committee as the Committee from time to time may designate
shall preside at such meetings.

The Executive Committee shall possess and exercise to the extent permitted by
law all of the powers of the Board of Directors, except when the latter is in
session, and shall keep minutes of its proceedings, which shall be presented to
the Board of Directors at its next subsequent meeting. All acts done and powers
and authority conferred by the Executive Committee from time to time shall be
and be deemed to be, and may be certified as being, the act and under the
authority of the Board of Directors.

A majority of the Committee shall constitute a quorum, but the Committee may act
only by the concurrent vote of not less than one-third of its members, at least
one of whom must be a director other than an officer. Any one or more directors,
even though not members of the Executive Committee, may attend any meeting of
the Committee, and the member or members of the Committee present, even though
less than a quorum, may designate any one or more of such directors as a
substitute or substitutes for any absent member or members of the Committee, and
each such substitute or substitutes shall be counted for quorum, voting, and all
other purposes as a member or members of the Committee.

SECTION 2. There shall be an Audit Committee appointed annually by resolution

to time fix a quorum for meetings of the Committee. Such Committee shall conduct

Company, to make studies of the Company's assets and liabilities as the
Committee may request and to make an examination of the accounting and auditing
methods of the Company and its system of internal protective controls to the
extent considered necessary or advisable in order to determine that the
operations of the Company, including its fiduciary departments, are being
audited by the General Auditor in such a manner as to provide prudent and
adequate protection. The Committee also may direct the General Auditor to make
such investigation as it deems necessary or advisable with respect to the
Company, its various departments and the conduct of its operations. The
Committee shall hold regular quarterly meetings and during the intervals thereof
shall meet at other times on call of the Chairman.

SECTION 3. The Board of Directors shall have the power to appoint any other
Committees as may seem necessary, and from time to time to suspend or continue
the powers and duties of such Committees. Each Committee appointed pursuant to
this Article shall serve at the pleasure of the Board of Directors.

SECTION 1. The Company shall, to the fullest extent permitted by Section 7018 of
the New York Banking Law, indemnify any person who is or was made, or threatened
to be made, a party to an action or proceeding, whether civil or criminal,
whether involving any actual or alleged breach of duty, neglect or error, any
accountability, or any actual or alleged misstatement, misleading statement or
other act or omission and whether brought or threatened in any court or
administrative or legislative body or agency, including an action by or in the
right of the Company to procure a judgment in its favor and an action by or in
the right of any other corporation of any type or kind, domestic or foreign, or
any partnership, joint venture, trust, employee benefit plan or other
enterprise, which any director or officer of the Company is servicing or served
in any capacity at the request of the Company by reason of the fact that he, his
testator or intestate, is or was a director or officer of the Company, or is
serving or served such other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise in any capacity, against judgments,
fines, amounts paid in settlement, and costs, charges and expenses, including
attorneys' fees, or any appeal therein; provided, however, that no
indemnification shall be provided to any such person if a judgment or other
final adjudication adverse to the director or officer establishes that (i) his
acts were committed in bad faith or were the result of active and deliberate
dishonesty and, in either case, were material to the cause of action so
adjudicated, or (ii) he personally gained in fact a financial profit or other
advantage to which he was not legally entitled.

SECTION 2. The Company may indemnify any other person to whom the Company is
permitted to provide indemnification or the advancement of expenses by
applicable law, whether pursuant to rights granted pursuant to, or provided by,
the New York Banking Law or other rights created by (i) a resolution of
stockholders, (ii) a resolution of directors, or (iii) an agreement providing
for such indemnification, it being expressly intended that these By-Laws
authorize the creation of other rights in any such manner.

SECTION 3. The Company shall, from time to time, reimburse or advance to any
person referred to in Section 1 the funds necessary for payment of expenses,
including attorneys' fees, incurred in connection with any action or proceeding
referred to in Section 1, upon receipt of a written undertaking by or on behalf
of such person to repay such amount(s) if a judgment or other final adjudication
adverse to the director or officer establishes that (i) his acts were committed
in bad faith or were the result of active and deliberate dishonesty and, in
either case, were material to the cause of action so adjudicated, or (ii) he
personally gained in fact a financial profit or other advantage to which he was
not legally entitled.

SECTION 4. Any director or officer of the Company serving (i) another
corporation, of which a majority of the shares entitled to vote in the election
of its directors is held by the Company, or (ii) any employee benefit plan of
the Company or any corporation referred to in clause (i) in any capacity shall
be deemed to be doing so at the request of the Company. In all other cases, the
provisions of this Article V will apply (i) only if the person serving another
corporation or any partnership, joint venture, trust, employee benefit plan or
other enterprise so served at the specific request of the Company, evidenced by
a written communication signed by the Chairman of the Board, the Chief Executive
Officer or the President, and (ii) only if and to the extent that, after making
such efforts as the Chairman of the Board, the Chief Executive Officer or the
President shall deem adequate in the circumstances, such person shall be unable
to obtain indemnification from such other enterprise or its insurer.

SECTION 5. Any person entitled to be indemnified or to the reimbursement or
advancement of expenses as a matter of right pursuant to this Article V may
elect to have the right to indemnification (or advancement of expenses)
interpreted on the basis of the applicable law in effect at the time of
occurrence of the event or events 

<PAGE>   16

giving rise to the action or proceeding, to the extent permitted by law, or on
the basis of the applicable law in effect at the time indemnification is sought.

SECTION 6. The right to be indemnified or to the reimbursement or advancement of
expense pursuant to this Article V (i) is a contract right pursuant to which the
person entitled thereto may bring suit as if the provisions hereof were set
forth in a separate written contract between the Company and the director or
officer, (ii) is intended to be retroactive and shall be available with respect
to events occurring prior to the adoption hereof, and (iii) shall continue to
exist after the rescission or restrictive modification hereof with respect to
events occurring prior thereto.

SECTION 7. If a request to be indemnified or for the reimbursement or
advancement of expenses pursuant hereto is not paid in full by the Company
within thirty days after a written claim has been received by the Company, the
claimant may at any time thereafter bring suit against the Company to recover
the unpaid amount of the claim and, if successful in whole or in part, the
claimant shall be entitled also to be paid the expenses of prosecuting such
claim. Neither the failure of the Company (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination
prior to the commencement of such action that indemnification of or
reimbursement or advancement of expenses to the claimant is proper in the
circumstance, nor an actual determination by the Company (including its Board of
Directors, independent legal counsel, or its stockholders) that the claimant is
not entitled to indemnification or to the reimbursement or advancement of
expenses, shall be a defense to the action or create a presumption that the
claimant is not so entitled.

SECTION 8. A person who has been successful, on the merits or otherwise, in the
defense of a civil or criminal action or proceeding of the character described
in Section 1 shall be entitled to indemnification only as provided in Sections 1
and 3, notwithstanding any provision of the New York Banking Law to the
contrary.


                                   ARTICLE VI

                                      SEAL


SECTION 1. The Board of Directors shall provide a seal for the Company, the
counterpart dies of which shall be in the charge of the Secretary of the Company
and such officers as the Chairman of the Board, the Chief Executive Officer or
the Secretary may from time to time direct in writing, to be affixed to
certificates of stock and other documents in accordance with the directions of
the Board of Directors or the Executive Committee.

SECTION 2. The Board of Directors may provide, in proper cases on a specified
occasion and for a specified transaction or transactions, for the use of a
printed or engraved facsimile seal of the Company.


                                   ARTICLE VII

                                  CAPITAL STOCK


SECTION 1. Registration of transfer of shares shall only be made upon the books
of the Company by the registered holder in person, or by power of attorney, duly
executed, witnessed and filed with the Secretary or other proper officer of the
Company, on the surrender of the certificate or certificates of such shares
properly assigned for transfer.

                                   AMENDMENTS
