ITEM 1. BUSINESS
 
GENERAL
 
     Since 1973, WFS Financial Inc, a California corporation ("WFS" or the
"Company"), and its predecessors, has been in the business of purchasing fixed
rate consumer auto loans ("contracts") from its network of new and used car
dealers ("dealers"). WFS then securitizes the majority of these contracts
through underwritten public sales of AAA/Aaa rated asset backed securities and
retains the rights to service them. As of February 28, 1999, WFS purchased
contracts in California and 41 other states. Over the past five years, WFS has
increased its volume of contracts purchased from $1.2 billion in 1994 to $2.7
billion in 1998, representing an 18% compounded annual growth rate. WFS serviced
a total of $4.4 billion, $3.7 billion and $3.0 billion of contracts at December
31, 1998, 1997 and 1996, respectively.
 
     The following is a roll forward of serviced contract activity for the last
three years:

     Based upon published data, the auto finance industry exceeded $500 billion
in 1998, and is the second largest consumer finance market in the United States.
The Company's contract purchase and securitization activities have made it one
of the largest sellers, in aggregate dollar amount, of auto receivable backed
securities in the United States after the captive auto finance companies,
Chrysler Credit Corporation ("Chrysler Credit"), General Motors Acceptance
Corporation ("GMAC") and Ford Motor Credit Company ("Ford Credit"). Aside from
these and other captive auto finance companies, the balance of the auto finance
industry is highly fragmented among banks, credit unions, savings associations
and independent auto finance companies.
 
     WFS competes in both the prime and non-prime segments of the auto finance
industry. During 1998, WFS purchased approximately 69% of its contracts from
franchised new car dealers, 30% from independent used car dealers and originated
1% directly from consumers. During that same period, contracts for new and used
autos represented 21% and 79%, respectively, of the Company's volume of
contracts purchased. References herein to "purchase" and "contracts" refer to
both the purchase of contracts by WFS from new and used car dealers and the
origination of auto loans directly from consumers by WFS.
 
     The following table presents a summary of the Company's production volumes
of prime and non-prime contracts and those secured by new and used vehicles for
the periods indicated below:

     WFS purchases contracts across the full spectrum of prime and non-prime
credit quality contracts and offers competitive rates commensurate with the risk
inherent in its obligor's ability to make payments under
 
                                        1

their contracts. During 1997 and 1998, WFS tightened its underwriting standards
on the lowest tier of its non-prime contract purchases based upon WFS' credit
performance experience. As a result, WFS purchased a higher percentage of prime
contracts in 1998. This shift in product mix is providing WFS with higher
returns based upon loss expectations.
 
THE HISTORY OF WFS
 
     Westcorp, the ultimate parent of WFS, was formed in 1973 as the holding
company for Western Thrift and Loan Association ("Western Thrift"), a California
licensed thrift and loan association founded in 1972. Western Thrift was
involved in auto finance activities from its incorporation until its merger with
Western Financial Bank ("the Bank") in 1982, at which time the auto finance
activities of Western Thrift were continued by the Bank. In 1988, Westcorp
Financial Services, Inc. ("Westcorp Financial") was incorporated as a
wholly-owned consumer finance subsidiary of the Bank to provide auto finance
services to a market not serviced by the Bank's auto finance division.
 
     On May 1, 1995, the Bank transferred its auto finance division to Westcorp
Financial and changed the name of Westcorp Financial to WFS Financial Inc. In
connection with that acquisition, the Bank transferred to WFS all assets
relating to its auto finance division including the contracts held on balance
sheet and all interests of the Bank in the excess spread payable from the
outstanding securitization transactions. The Bank also transferred all of the
outstanding stock of WFS Financial Auto Loans, Inc. ("WFAL") and WFS Financial
Auto Loans 2, Inc. ("WFAL2"), the securitization entities of the Bank, thereby
making these companies subsidiaries of WFS. In August 1995, WFS sold
approximately 20% of its shares in a public offering. Currently, the Bank owns
87% of WFSs stock.
 
BUSINESS STRATEGIES
 
     WFS pursues its business objective of maximizing earnings through the
profitable purchase, securitization and servicing of contracts using four
strategies: (i) provide a consistent source of prime and non-prime financing to
its nationwide network of dealers, (ii) maintain solid asset quality, (iii)
maximize liquidity through relationship with parent and securitization
transactions, and (iv) improve operating efficiencies.
 
  Prime and Non-Prime Financing
 
     WFS has provided a consistent source of auto financing since 1973 and is
dedicated to continuing to provide a consistent source of prime and non-prime
financing to its network of over 11,300 dealers. While other lenders have
retreated from time to time, WFS has consistently and continuously expanded its
operations in the auto finance market. WFS' focus is to provide each dealer
maximum service by providing a single source of contact to meet the dealer's
prime and non-prime financing needs. Substantially all contracts are purchased
without recourse to the dealer. WFS pays an upfront dealer participation to the
originating dealer for each contract purchased.
 
  Maintain Solid Asset Quality
 
     Consistent and Expeditious Underwriting -- The Company relies on a
combination of multiple credit scoring models, system controlled underwriting
policies and the judgment of its trained credit analysts to make risk based
credit decisions. In order to make timely credit decisions, WFS personnel are
trained to obtain, examine and verify all relevant underwriting information
quickly utilizing the Company's automated credit application processing system.
The Company's credit analysts are closely monitored by management through trend
analysis, risk management reporting and internal quality control professionals
to insure adherence to the Company's underwriting guidelines. Credit analyst
lending levels and approval authorities are established based on the
individual's credit experience, portfolio performance, Credit Manager audit
results and quality control review results. The goal in underwriting contracts
is to correctly determine whether an applicant has the ability and intent to
perform on his or her obligations under the contract, thereby maximizing returns
while optimizing credit quality.
 
                                        2
<PAGE>   5
 
     Collection Activities -- WFS services all of the contracts it purchases,
both those held by the Company and those sold in securitization transactions.
The servicing process includes the routine collection and allocation of payments
to WFS or to the appropriate securitization transaction into which the contract
has been sold.
 
     WFS has developed procedures for the early identification and cure of
delinquent contracts. During the early stages of delinquency, WFS utilizes an
automated telephone dialing system to aid in the servicing and collection
process. If the early collection efforts do not result in a satisfactory
resolution of the delinquent account, then the account is forwarded to the
appropriate regional collection specialist.
 
     If satisfactory payment arrangements are not made, the automobile is
generally repossessed within 60 to 90 days of the date of delinquency, subject
to compliance with applicable law. WFS uses independent contractors to perform
repossessions. The automobile remains in the custody of WFS for 15 days (or
longer if required by local law) to provide the obligor the opportunity to
redeem the contract. If after the redemption period the delinquency is not
cured, WFS writes down the vehicle to fair value and reclassifies the contract
as a repossessed asset. After the redemption period expires, WFS prepares the
automobile for sale. WFS sells substantially all repossessed automobiles through
wholesale auto auctions, subject to applicable law. WFS does not provide the
financing on repossessions sold. WFS uses regional remarketing departments to
sell its repossessed vehicles. Once the vehicle is sold, any remaining
deficiency balances are then charged off. At December 31, 1998, the total amount
of repossessed autos managed by WFS was $7.8 million or 0.18% of the total
serviced portfolio compared with $9.7 million or 0.26% of the total serviced
portfolio at December 31, 1997.
 
     After chargeoff, WFS will seek to collect deficient balances through its
centralized asset recovery center ("ARC"). The ARC will first attempt to collect
directly from the obligor with its in-house collection staff. If efforts are not
successful, the ARC will seek a deficiency judgment through a small claims court
procedure, where available, or an attorney employed by WFS takes more formal
judicial action against customers with deficiency balances in excess of that
which may be brought in a small claims court proceeding. In some cases,
particularly when the likelihood of recovery is believed to be less likely, the
account is assigned to a collection agency for final resolution. The ARC will
attempt to obtain vehicles that could not be found for repossession by skip
tracing to locate the vehicle. WFS also monitors payment plans on those obligors
who have filed for bankruptcy. If the obligor is not following the payment plan
stipulated by the courts in a Chapter 13 bankruptcy, WFS will seek a judgment
for dismissal or discharge from the bankruptcy court, or will seek an order
permitting it to repossess the vehicle.
 
  Maximize Liquidity Through Relationship with Parent and Securitization
Transactions
 
     As a subsidiary of a federally chartered savings bank, WFS may utilize the
Bank's liquidity sources through the use of intercompany financing arrangements.
See "Transactions with Related Parties". WFS believes that this relationship
provides it a competitive advantage relative to other independent auto finance
companies that must enter into financing arrangements with outside financial
institutions. WFS also utilizes both securitization and hedging strategies to
leverage its capital efficiently and substantially reduce its interest rate
risk, while also limiting its credit loss exposure on contracts sold. See
"Hedging and Securitization". During the third quarter of 1998 when adverse
conditions existed in the secondary markets, WFS was able to increase its
borrowing with its parent and delay its securitization transaction until market
conditions improved. WFS expects to continue to utilize both its funding sources
with its parent company and securitization as conditions warrant.
 
  Improve Operating Efficiencies
 
     In 1998, the Company completed a restructuring plan initially announced on
February 10, 1998. The plan had four objectives: to reduce operating costs, to
increase contract production volume, to strengthen credit quality and to improve
the quality of personnel. The plan was achieved in two phases. Phase I of the
plan, completed in the first quarter of 1998, consisted of the restructuring of
operations in the Western United
 
                                        3
<PAGE>   6
 
States. Phase II of the plan, completed in the third quarter of 1998 and
patterned after Phase I, consisted of the restructuring of operations in the
Central and Eastern United States.
 
     As a result of the restructuring, a total of 400 positions, or 19% of the
Company's workforce, were eliminated and 96 offices were closed. The Company now
purchases contracts through 21 regional business centers ("RBCs") and 26
satellite offices, each offering the full spectrum of prime and non-prime
products. The total pre-tax restructuring charge in 1998 for the completed plan
was $15.0 million. Restructuring related costs included $1.8 million for
employee severance and $13.2 million for lease termination fees and the write
off of disposed assets. The restructuring charge was substantially utilized
during 1998. Operating costs as a percent of serviced contracts has declined
from 5.4% in 1997 to 3.8% in 1998, resulting in a decrease in operating costs of
$65 million on an annual run rate basis.
 
     Through the restructuring, WFS increased its contract production volume to
$2.7 billion compared with $2.3 billion in 1997. Prior to the restructuring, the
Company purchased contracts in 143 offices, each serving either the prime or
non-prime market. As part of the restructuring, the Company closed poorly
performing offices and combined its prime and non-prime marketing into a single,
unified marketing effort. By combining the marketing of the two products under a
single marketing force, WFS is able to more fully leverage its existing dealer
relationships across the full spectrum of credit.
 
     Each of the 47 offices underwrites contracts by employing separate credit
analysts that specialize in either reviewing prime or non-prime contracts. The
underwriting process is further enhanced by credit policies and contract
approval authorities controlled by the front-end contract production system and
through the use of the Company's proprietary scorecard which was implemented in
the fourth quarter of 1998. See "Maintain Solid Asset Quality -- Consistent and
Expeditious Underwriting."
 
     As part of the restructuring, early delinquency collection efforts were
centralized at two national servicing centers that employ automated queuing and
dialing techniques to contact customers. When these efforts are unsuccessful,
the collection process is transferred to the RBCs where loan service counselors
undertake more extensive collection efforts up to and including repossession.
The Company plans to further improve its collection efforts by implementing a
new collection system, including risk-based collections, in 1999.
 
     During 1998, the Company also established a more effective management
structure. Each RBC is managed by a RBC manager who directs and is responsible
for the performance of the region. Four functional managers who oversee
marketing, credit, collections and operations report directly to the RBC
manager. This organization is designed to provide overall coordination of the
activities within the RBC with appropriate focus and specialization in each of
these four critical business areas. Each of these critical functions also has a
national director who provides expertise, training and policy development,
management and enforcement. This matrix structure has been effective in
providing greater oversight, compliance and focus for each aspect of the
organization and has helped standardize operating practices by identifying best
practices and employing these practices throughout the organization.
 
HEDGING AND SECURITIZATION
 
     The Company employs a hedging and securitization strategy to leverage its
capital efficiently, lock in interest rate spreads and materially reduce its
interest rate risk while also limiting its credit loss exposure on contracts
sold. Securitizations enable the Company to sell contracts on a regular basis
while continuing to receive servicing fees and to use the proceeds from such
sales to purchase additional contracts.
 
     Between December 1985 and December 1998, WFS sold, in 43 transactions,
approximately $11.9 billion of contracts in publicly underwritten securitization
transactions. WFS also sold $1.0 billion of contracts in February of 1999. The
first issue was rated AA by Standard & Poor's Rating Service, a division of
McGraw-Hill, Inc. ("S&P") and Aa by Moody's Investor Service, Inc. ("Moody's")
and all 43 issues since that time were rated AAA by S&P and Aaa by Moody's,
their highest rating categories, as a result of the structure of the
transactions and the quality of the contracts securitized or the credit
enhancement provided by Financial Security Assurance Inc. ("FSA"). In all of its
securitization transactions, WFS continues to service the contracts sold. Each
transaction is independent of all others, with no cross-collateralization or
cross-default
 
                                        4

provisions applicable. Each securitization transaction and each class of
security with a maturity date prior to the date hereof has been paid in full on
or before its contracted final maturity date and no recourse has been made to
FSA on any transaction.
 
     In 1996, WFS began to securitize its contracts using an owner trust
structure, issuing both collateralized notes and pass-through certificates.
Securitizations using the owner trust structure are treated as sales without
recourse thereby removing the contracts sold from the balance sheet. WFS retains
the servicing of the contracts sold to the owner trust and receives excess
interest from the contracts sold. The owner trust structure enables WFS to
maximize the residual return from a securitization transaction by matching the
yield paid to the investor to the yield curve existing at the time the
securitization transaction is consummated. WFS securitized $1.9 billion, $2.2
billion and $2.1 billion of contracts using this structure during 1998, 1997 and
1996, respectively.
 
     WFS derives multiple benefits from the securitization of contracts,
including a stable source of low cost funding, reduction of interest rate and
credit risk for sold contracts, enhanced return on assets and regulatory
compliance.
 
            Low Cost of Funds -- Other than the first transaction, all of the
            securitization transactions completed by WFS to date hereof have
            been rated in the highest credit categories by both S&P and Moody's.
            Accordingly, WFS has been able to sell these securities at
            attractive yields relative to its cost of alternative funding
            sources at the time of pricing.
 
            Reduction of Interest Rate Risk -- Since these transactions are
            structured as asset sales, interest rate risk is largely transferred
            to the third party buyers of the related asset backed securities.
            The interest rate and maturity of the pool of contracts have
            durations that are matched with the securities, thereby locking-in
            the excess spread of the contracts securitized.
 
            Enhanced Return on Assets -- These securitizations reduce the level
            of average assets on balance sheet while providing WFS with ongoing
            retained interest income and contractual servicing fee income.
 
            Regulatory Compliance -- As a Federal savings bank, the Bank may not
            have more than 35% of its consolidated assets invested in consumer
            loans, including contracts, purchased from dealers. Contracts
            securitized are not included in the calculation of consolidated
            assets.
 
SUBSIDIARIES
 
  WFS Financial Auto Loans, Inc.
 
     WFAL is a wholly-owned, limited purpose subsidiary of WFS. WFAL was

TRANSACTIONS WITH RELATED PARTIES
 
  Senior Note
 
     WFS has $125 million outstanding under the terms of the Senior Note from
the Bank. The Senior Note provides for principal payments of $25 million per
year, commencing on April 30, 1999 and continuing through its final maturity,
April 30, 2003. During 1998, the Company made a paydown of $15.0 million without
prepayment penalties. Interest payments on the Senior Note are due quarterly, in
arrears, calculated at the rate of 7.25% per annum. The Senior Note is not
secured. Pursuant to the terms of the Senior Note, WFS may not incur any other
indebtedness which is senior to the obligations evidenced by the Senior Note
except for (i) indebtedness collateralized or secured under the Line of Credit
and (ii) indebtedness for similar types of warehouse lines of credit. The Senior
Note had interest expense of $9.0 million and $9.1 million for 1998 and 1997,
respectively.
 
  Promissory Note
 
     WFS has $50 million outstanding under the terms of a Promissory Note with
the Bank dated August 1, 1997. The Promissory Note provided for principal
payments in two equal annual installments of $25 million. Subsequent to year
end, the Promissory Note was amended to increase the amount by $30 million and
to provide for principal payments in two equal annual installments of $40
million commencing on July 31, 2001. Interest payments on the Promissory Note
are due quarterly, in arrears, calculated at the rate of 9.42% per annum.
Pursuant to the terms of the Promissory Note and the Senior Note, WFS may not
incur any other indebtedness which is senior to the obligations evidenced by the
Promissory Note except for (i) indebtedness under the Senior Note (ii)
indebtedness collateralized or secured under the Line of Credit and (iii)
indebtedness for similar types of warehouse lines of credit. The Promissory Note
had interest expense of $4.7 million and $2.0 million during 1998 and 1997,
respectively.
 
  Line of Credit
 
     The Line of Credit extended by the Bank permits WFS to draw up to $900
million as needed to be used in its operations. WFS does not pay a commitment
fee for the Line of Credit. The term of the Line of Credit commenced on May 1,
1995 and terminates on December 31, 1999 except that such term may be extended
by WFS for additional periods up to 56 months under certain conditions. When
secured by contracts, the first $600 million of the Line of Credit carries an
interest rate equal to the Federal composite commercial paper rate plus 10 basis
points, with the margin increasing to 50 basis points to the extent the
obligation is not secured. The next $300 million of the Line of Credit carries
an interest rate equal to the Federal composite commercial paper rate plus 40
basis points when secured by contracts, with the margin increasing to 80 basis
points to the extent the obligation is not secured. Interest on the amount
outstanding under the Line of Credit is paid monthly, in arrears, and is
calculated on the average amount outstanding that month. The Bank has the right
under the Line of Credit to refuse to permit additional amounts to be drawn on
the Line of Credit if, in the Bank's discretion, the amount sought to be drawn
will not be used to finance the Company's purchase of contracts or other working
capital requirements. At December 31, 1998, $555 million was outstanding on the
Line of Credit. Interest expense was $16.8 million for the year ended December
31, 1998. The average amount outstanding during 1998 was $278 million.
 
  Short Term Investments-Parent
 
     WFS invests its excess cash at the Bank under an Investment Agreement. The
Bank pays WFS an interest rate equal to the Federal composite commercial paper
rate on this excess cash. The weighted average interest rate was 5.45% and 5.78%
for 1998 and 1997, respectively. The average balance of the excess cash was $9.0
million and the interest income earned was $0.5 million during 1998. At December
31, 1998, WFS held no excess cash with the Bank under the Investment Agreement.
 
                                        6
<PAGE>   9
 
  WFS Reinvestment Contract
 
     Pursuant to a series of agreements to which WFS, the Bank and WFAL2, among
others, are parties, WFS is able to access the cash flows of each of the
outstanding securitization transactions and the cash held in each spread account
for each of those transactions. WFS is permitted to use that cash as it
determines, including in its ordinary business activities of originating
contracts.
 
     In each securitization transaction, the Bank and WFAL2 have entered into a
reinvestment contract, which is deemed to be an eligible investment under the
relevant securitization agreements. The securitization agreements require,
provided certain conditions are met, that all cash flows of the relevant trust
and the associated spread accounts be invested in the applicable reinvestment
contract. A limited portion of the invested funds may be used by WFAL2 and the
balance may be used by the Bank. The Bank makes its portion available to WFS
pursuant to the terms of the WFS Reinvestment Contract ("RIC"). Under the RIC,
WFS receives access to all of the cash available to the Bank under each trust
reinvestment contract and is obligated to repay to the Bank an amount equal to
the cash so used when needed by the Bank to meet its obligations under the
individual trust reinvestment contracts. With the portion of the cash available
to it under the individual trust reinvestment contracts, WFAL2 purchases
contracts from WFS pursuant to the terms of Sale and Servicing Agreements.
 
     Pursuant to an agreement with FSA, the trust reinvestment contracts may be
eligible investments provided the Bank and WFAL2 pledge adequate collateral to
secure their respective obligations. In accordance with this agreement, the Bank
and WFAL2 pledge property owned by each for the benefit of the trustee of each
trust and FSA. WFS pays the Bank a fee equal to 12.5 basis points of the amount
of collateral pledged by the Bank as consideration for the pledge of collateral
by the Bank and for WFS' access to cash under the RIC. During 1998, WFS paid the
Bank $0.7 million for this purpose. As WFAL2 directly utilizes the cash made
available to it to purchase contracts for its own account from WFS, no
additional consideration from WFS is required to support WFAL2's pledge of its
property under the agreement with FSA. While WFS is under no obligation to
repurchase contracts from WFAL2 to the extent WFAL2 needs to sell any such
contracts to fund its repayment obligations under the trust reinvestment
contracts, it is anticipated that WFS would prefer to purchase those contracts
than for WFAL2 to sell those contracts to a third party. The RIC, by its terms,
is to remain in effect so long as any of the trust reinvestment contracts is an
eligible investment for its related securitization transaction. During 1998, the
average amount outstanding under the RIC was $585 million and the average amount
of contracts purchased by WFAL2 from WFS was $119 million. At December 31, 1998,
the amount outstanding under the RIC was $364 million and the amount of
contracts held by WFAL2 purchased from WFS was $355 million.
 
  Tax Sharing Agreement
 
     WFS and its subsidiaries (WFAL, WFAL2 and WFSII) are parties to a tax
sharing agreement with Westcorp, the Bank and other subsidiaries of Westcorp,
pursuant to which a consolidated federal tax return is filed for all of the
parties to the agreement. Under the agreement, the tax due by the group is
allocated to each member based upon the relative percentage of each member's
taxable income to that of all members. Each member pays to Westcorp its
estimated share of that tax liability when otherwise due, but in no event may
the amount paid exceed the amount of tax which would have been due if a member
were to file a separate return. A similar process is used with respect to state
income taxes, for those states which permit the filing of a consolidated or
combined return. Tax liabilities to states which require the filing of separate
tax returns for each company are paid by each company. The term of the tax
sharing agreement commenced on the first day of the consolidated return year
beginning January 1, 1994 and continues in effect until the parties to the tax
sharing agreement agree in writing to terminate it. See "Note 12 -- Income
Taxes" to WFS' Consolidated Financial Statements.
 
  Management Agreements
 
     WFS has entered into certain management agreements with the Bank and
Westcorp pursuant to which WFS pays its allocated portion of certain costs and
expenses incurred by the Bank and Westcorp with respect
 
                                        7
<PAGE>   10
 
to services or facilities of the Bank and Westcorp used by WFS or its
subsidiaries, including their principal office facilities, field offices of WFS
and overhead and employee benefits pertaining to Bank and Westcorp employees who
also provide services to WFS or its subsidiaries. Additionally, as part of these
management agreements, the Bank and Westcorp have agreed to reimburse WFS for
similar costs incurred. The management agreements may be terminated by any party
upon 5 days prior written notice without cause, or immediately in the event of
the other party's breach of any covenant, obligation, or duty contained in the
applicable management agreement or for violation of law, ordinance, statute,
rule or regulation governing either party to the applicable management
agreement.
 
     WFS has entered into an agreement with Westran Services Corp ("Westran"),
which is a subsidiary of Westcorp, to receive travel related services. WFS
believes that the services rendered by Westran are reasonable and representative
of what such costs would have been had WFS used an unaffiliated entity for such
services. Total amounts paid to Westran in 1998, 1997 and 1996 was $0.2 million,
$0.1 million, and $0.4 million, respectively
 
     WFS leases office space for its Encino, California office from Insurance
Company of the West ("ICW"), an affiliate of Mr. Rady, Chairman of WFS, the Bank
and Westcorp. The basic annual rent is adjusted annually and includes a portion
of direct operating expenses. The Encino lease arrangement expires in 2001. The
Company paid $152,211 in rent to ICW in 1998.
 
     The Kearny Mesa Business Center is landlord to WFS' office in San Diego.
Kearny Mesa Business Center is an affiliate of Mr. Rady. The total amount paid
in 1998 pursuant to this lease, which expires in 2001, was $53,057.
 
RELATIONSHIP WITH THE BANK AND ITS AFFILIATES
 
     In the opinion of the Company, the transactions described herein under the
caption "Transactions with Related Parties" have been on terms no less favorable
to WFS than could be obtained from unaffiliated parties, notwithstanding that
the transactions were not negotiated at arm's length. However, the transactions
were approved by the entire Board of Directors of WFS, the Bank and Westcorp,
including all of their respective independent directors. Furthermore, any future
transactions with the Bank or affiliated persons will continue to be approved by
a majority of disinterested directors of the Company. See "Supervision and
Regulation -- Westcorp".
 
SUPERVISION AND REGULATION
 
THE COMPANY
 
     The Company is an operating subsidiary of the Bank and a second tier
subsidiary of Westcorp. The Company purchased automobile loans in 42 states at
February 28, 1999. While WFS has historically been licensed in each state in
which it operates, WFS is now relying upon the preemption of such state
licensing laws afforded by regulations adopted by the Office of Thrift
Supervision ("OTS"). To the extent WFS relies on preemption it is no longer
subject to audit and examination by the applicable state agencies for these
states, but remains subject to examination and supervision by the OTS and the
Federal Deposit Insurance Corporation ("FDIC"), the Federal entity which
provides insurance of deposits to the Bank. WFS engages local counsel familiar
with the applicable consumer finance and auto finance, licensing and titling
laws and regulations of general application of each of the states in which it
has offices and from which it purchases contracts to the extent it purchases
contracts out of states in which it has no office. At December 31, 1998, and as
of the date hereof, WFS believes that it is in compliance with the laws and
regulations applicable to each of its offices in these states.
 
     Numerous federal and state consumer protection laws and regulations not
preempted by OTS regulations impose requirements applicable to the contracts
originated and serviced by WFS. Among these enactments are the federal
Truth-in-Lending Act, the Federal Trade Commission Act, the Fair Credit Billing
Act, The Fair Credit Reporting Act, the Equal Credit Opportunity Act, the Fair
Debt Collection Practices Act and the California Rees-Levering Act and similar
retail installment sales laws and similar laws of other states in which
 
                                        8
<PAGE>   11
 
WFS originates contracts. Most of the states in which WFS is originating
contracts have statutes or regulations pertaining to the repossession and sale
process the Company must follow when seeking to recover on defaulted contracts.
Generally, the Company must follow those requirements with precision to ensure
its ability to maximize its recovery on a defaulted contract. In addition, some
states, such as Texas and Washington, have consumer protection laws which limit
the assets WFS may seize in order to recover on any deficiency following
repossession and sale of the vehicle which secures a defaulted contract.
 
     As an operating subsidiary of the Bank, WFS is precluded by regulations of
the OTS from engaging in any business activity which the Bank could not itself
undertake. All of its current business activities are permitted activities for
the Bank. Also, as WFS is an operating subsidiary of the Bank, the Bank is
required to retain ownership of at least a majority of the voting stock of WFS.
WFS may not engage in any new business activity nor may it acquire a business
from a third party, even if such business activities are permitted to the Bank
and thereby to WFS, until the Bank has first given notice thereof to the FDIC
and to the OTS.
 
WESTCORP
 
     Westcorp, by virtue of its ownership of the Bank, is a savings and loan
holding company within the meaning of the Home Owners' Loan Act, as amended
("HOLA"). Savings and loan holding companies, their savings association
subsidiaries and subsidiaries thereof are extensively regulated under federal
laws.
 
     Under the HOLA, the OTS is permitted to take substantive action when it
determines that there is reasonable cause to believe that the continuation by a
savings and loan holding company of any particular activity constitutes a
serious risk to the financial safety, soundness or stability of that holding
company's subsidiary savings association. Specifically, the OTS may, as
necessary: (i) limit the payment of dividends by the Bank; (ii) limit
transactions between the Bank, Westcorp and the subsidiaries or affiliates of
either; and (iii) limit any activities of Westcorp that might create a serious
risk that the liabilities of Westcorp and its affiliates may be imposed on the
Bank or subsidiaries of the Bank. Any such limits may be issued in the form of
regulations, or a directive having the effect of a cease and desist order.
 
     Savings association subsidiaries of a savings and loan holding company, and
subsidiaries of such savings associations, are limited by HOLA in the type of
activities and investments in which they may participate if the investment
and/or activity involves an affiliate. In general, savings association
subsidiaries of a savings and loan holding company, and the subsidiaries of such
savings association, are subject to Sections 23A and 23B of the Federal Reserve
Act ("FRA") in the same manner and to the same extent as if the savings
association or its subsidiary were a member bank of the Federal Reserve System,
as well as being subject to similar regulations adopted by the OTS. Section 23A
of the FRA puts certain quantitative limitations, based upon a percentage of a
bank's capital stock and surplus, on certain transactions between a bank or its
subsidiary and an affiliate, including transactions involving (i) loans or
extensions of credit to the affiliate; (ii) the purchase of or investment in
securities issued by an affiliate; (iii) purchase of certain assets from an
affiliate; (iv) the acceptance of securities issued by an affiliate as security
for a loan or extension of credit to any person; or (v) the issuance of a
guarantee, acceptance or letter of credit on behalf of an affiliate. The Board
of Governors of the Federal Reserve System (the "Board") has revised the
definition of capital stock and surplus for purposes of Section 23A to conform
that definition to that used by the Board in calculating the limits in
Regulation O for insider lending and by the Office of the Comptroller of the
Currency ("OCC") in calculating the limit on loans by a national bank to a
single borrower. The revised definition will permit subordinated debt issued by
the Bank that qualifies for inclusion in Tier 2 capital to be included in the
calculation of capital stock and surplus.
 
     In addition, under Section 23B, transactions between a bank or its
subsidiary and an affiliate must meet certain qualitative limitations. Such
transactions must be on terms at least as favorable to the bank or its
subsidiary as transactions with unaffiliated companies.
 
     Section 11 of the HOLA also specifically prohibits a savings association
subsidiary of the savings and loan holding company, or a subsidiary of that
savings association, from making a loan or extension of credit to an affiliate
(which also includes, under most circumstances, a purchase of assets from an
affiliate that is subject to the affiliate's agreement to repurchase those
assets) unless that affiliate is engaged only in activities
 
                                        9
<PAGE>   12
 
permitted to bank holding companies under Section 4(c) of the Bank Holding
Company Act or from purchasing or investing in the securities of any affiliate
(other than a subsidiary of the savings association). The OTS regulations,
consistent with the provisions of Sections 23A and 23B, exclude transactions
between a savings association and its subsidiaries from the limitations of those
sections, but those regulations also define certain subsidiaries to be
affiliates and subject to the requirements of those sections. At the present
time, neither WFS nor any of its subsidiaries are within the definition of an
affiliate of the Bank for purposes of those regulations.
 
THE BANK
 
     The Bank, as the parent of WFS, is extensively regulated in its activities
by the OTS and the FDIC. Were the Bank to become insolvent or otherwise become
subject to being placed in conservatorship or receivership by the OTS, the FDIC
is required to be appointed as the conservator or receiver of the Bank. As
conservator or receiver, the FDIC would not have the authority to treat the
assets of WFS as the assets of the Bank, and the assets of WFS would not be
subject to the authority of the FDIC as conservator or receiver. However, as
conservator or receiver of the Bank, the FDIC, through control of the majority
of shares of the Common Stock of WFS, would be permitted to exercise control
over those shares to the same extent as the Bank prior to that conservatorship
or receivership. In addition, the FDIC as receiver or conservator would have the
right to preclude the Bank from making further advances under the Line of
Credit.
 
     An operating subsidiary, such as WFS, is permitted by the applicable
regulations of the OTS to only engage in such business activities as the Bank
itself is permitted to engage in for its own account. The investments of
operating subsidiaries are required to be consolidated with those of its parent
Federal savings bank for purposes of determining whether the parent Federal
savings bank, on a consolidated basis, is in full compliance with those
regulations limiting its activities to a percentage of its total consolidated
assets. In that regard, the Bank is permitted by the HOLA to invest up to 35% of
its consolidated assets in consumer loans, commercial paper and qualifying
corporate debt instruments; provided however, that all consumer loans in excess
of 30% of the Bank's consolidated assets must be made directly to the consumer.
Accordingly, not more than 30% of the Bank's consolidated assets may be invested
in contracts purchased from new and used car dealers. At December 31, 1998, WFS
held $825 million of contracts which were purchased from dealers, which amount
represented 21.8% of the Bank's consolidated assets. The Company was purchasing
contracts at the average rate of $223 million per month for the year then ended.
However, WFS also securitized $1.9 billion of such contracts in 1998, and an
additional $1.0 billion of such contracts in February of 1999. The Company
intends to regularly securitize contracts purchased from dealers to insure that
the Bank will remain in compliance with this regulatory limitation on its
consolidated activities.
 
     In addition, the regulations governing operating subsidiaries also require
that operating subsidiaries be subject to examination and supervision by the OTS
to the same extent as their parent Federal savings bank. The OTS may, following
such an examination, direct the parent savings association to take remedial
action to cure any violation of law, regulation or OTS policy, including
disposing of all or part of the subsidiary. In addition, the OTS may at any time
limit a savings association's investment in an operating subsidiary, limit any
operating subsidiary's activities or refuse to permit activities, for
supervisory, legal or safety and soundness reasons. WFS is not aware of any
actions it has taken or is planning to take which it believes would be deemed by
the OTS to be unsafe or unsound.
 
COMPETITION
 
     The auto finance business is highly competitive. With the successful
implementation of its business strategies, including its recent restructurings,
the Company believes it is competitive with other auto finance providers. WFS
strives to consistently apply established and time proven underwriting
standards, thus providing new and used car dealers a dependable source of auto
financing for contracts falling within the full spectrum of prime and non-prime
credit quality contracts. WFS then securitizes contracts to lock in excess
spread and enhance liquidity.
 
                                       10
<PAGE>   13
 
     Strong competition in the purchase of contracts is provided by Chrysler
Credit, GMAC, Ford Credit and other captive auto finance companies, commercial
banks, other consumer auto finance companies and credit unions. WFS competes for
the purchase of contracts on the basis of price and the level of service
provided to the dealers. The entity financing a dealer's inventory is ordinarily
that dealer's primary source of financing for auto sales. WFS does not finance
dealers' inventories. WFS depends on its share of a particular dealer's
contracts through the Company's strong personal relationship with that dealer.
That relationship is fostered by the promptness with which WFS can process and
approve an application submitted by a dealer and by the Company's expressed
willingness to work with its network of dealers and its flexibility in programs
offered.
 
     WFS must also compete with dealer interest rate subsidy programs offered by
the captive auto finance companies. However, frequently those programs are
limited to certain models or to certain loan terms which may not be attractive
to many new auto purchasers. WFS is more flexible in that it may offer longer
terms or be willing to accept a lower down payment than the captive auto finance
companies require. Also, these programs are rarely offered on used vehicles.
 
     The competition for contracts available within the prime and non-prime
credit quality contract spectrum is more intense when the rate of sales of autos
declines. While WFS has experienced consistent growth for many years, it can
give no assurance that it will be able to continue to do so. While auto leasing
has increased significantly in recent years, WFS has no present intention of
offering leases. WFS believes that many of such leases are for relatively short
terms of two or three years; therefore, the number of used auto contracts
available will continue to increase as these leases terminate. WFS believes that
this will continue to provide to it opportunities to purchase used auto
contracts in the quantity and of the quality it seeks.
 
YEAR 2000 STANDARDS FOR SAFETY AND SOUNDNESS
 
     The OTS issued interim guidelines establishing Year 2000 safety and
soundness standards for insured depository institutions. As an operating
subsidiary, the Company is subject to these guidelines. The development and
implementation of a written due diligence process to monitor and evaluate Year
2000 efforts by third-party service providers and software vendors is a critical
component of an institution's initial assessment period. The guidelines also
require each insured depository institution to develop and adopt a written
project plan that addresses each phase of the planning process. Insured
depository institutions are expected to perform adequate testing of admission
critical systems. The guidelines require an insured depository institution to
design contingency plans appropriate for the institutions technological systems
and operating structure that describe how the institution will mitigate the
risks associated with the failure of systems (the business resumption
contingency plan) and as applicable the failure to complete renovation testing
or implementation of a emission critical system. The guidelines require insured
depository institutions to implement a due diligence process that identifies
customers posing material Year 2000 risk, evaluate the Year 2000 preparedness,
assess the Year 2000 risk and implement the appropriate risk controls. Finally,
the guidelines require that the Board of Directors and management must be
involved in all stages of the institutions efforts to achieve the Year 2000

FORWARD-LOOKING STATEMENTS
 
     Included in our Business Section are several "forward-looking statements."
Forward-looking statements are those which use words such as "believe",
"expect", "anticipate", "intend", "plan", "may", "will", "should", "estimate",
"continue" or other comparable expression. These words indicate future events
and trends. Forward-looking statements are our current views with respect to
future even and financial performance. These forward-looking statements are
subject to many risks and uncertainties which could cause actual
 
                                       11
<PAGE>   14
 
results to differ significantly from historical results or from those
anticipated by us. The most significant risks and uncertainties we face are:
 
     1. the level of charge-offs, as an increase in the level of charge-offs
        will decrease our earnings;
 
     2. our ability to originate new contracts in a sufficient amount to reach
        our needs, as a decrease in the amount of contracts we originate will
        decrease our earnings;
 
     3. a decrease in the difference between the average interest rate we
        receive on the contracts we originate and the rate of interest we must
        pay to fund our cost of originating those contracts; as a decrease will
        reduce our earnings;
 
     4. the continued availability of sources of funding for our operations, as
        a reduction in the availability of funding will reduce our ability to
        originate contracts;
 
     5. maintaining the level of operating costs; as an increase in those costs
        will reduce our net earnings; and
 
     6. the Year 2000 issues; as a disruption of our collection efforts as a
        result of Year 2000 problems or an increase in our costs to correct Year
        2000 issues will reduce earnings.
 
     There are other risks and uncertainties we face, including the effect of
changes in general economic conditions and the effect of new laws, regulations
and court decisions. You are cautioned not to place undue reliance on our
forward-looking statements. We undertake no obligation to publicly update or
revise any forward-looking statements, whether as a result of new information,
future events or otherwise.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
OVERVIEW
 
     The primary sources of revenue for WFS are servicing income, net interest
income and gain on sale of contracts. During 1998, WFS purchased $2.7 billion of
contracts compared to $2.3 billion in 1997, an increase of 17%. After purchasing
contracts, WFS generally securitizes its contracts and earns servicing income.
Servicing income is primarily generated following the securitization of
contracts purchased by WFS and consists of: (i) contractual servicing fees, (ii)
retained interest income and (iii) other fee income such as late charges and
documentation fees which are earned regardless of whether or not a
securitization has occurred. Contractual servicing is the servicing fee
contractually due from a trust for servicing contracts which have been
securitized. Retained interest income represents realized gross retained
interest income from securitized contracts net of the amortization of the RISA.
Late charges, deferment fees, documentation fees and other fees are also
collected on contracts serviced and are retained by the Company. While contracts
are held on balance sheet, WFS earns net interest income. Net interest income is
the difference between the interest earned on contracts not yet sold in
securitization transactions and the interest paid on the liabilities used to
fund such contracts. Gain on sale of contracts is recognized based on the
estimated present value of the estimated future earnings to be received from the
excess spread on securitized contracts at the time of sale.
 
     The Company's securitization transactions involved the sale of contracts to
a trust in exchange for asset-backed securities issued by the trust which WFS
sells to investors. See "Business -- Hedging and Securitization". WFS continues
to service the contracts following their securitization and receives a
contractual servicing fee for such activities. In connection with the
securitization of contracts, WFS retains the right to receive excess spread
which is equal to the difference between the stated interest rate on the
contracts securitized and the interest rate on the asset-backed securities,
after adjustments for credit losses, administrative expenses and contractual
servicing fees. WFS securitized $1.9 billion, $2.2 billion and $2.1 billion of
contracts during 1998, 1997 and 1996, respectively.
 
     The following table lists each of the Company's outstanding securitization
transactions. Each of these transactions was rated AAA by S&P, and Aaa by
Moody's, their respective highest ratings. All earlier securitization
transactions and each class of security with an earlier maturity date were
timely paid off in full prior to December 31, 1998.

RESULTS OF OPERATIONS
 
  Servicing Income
 
     Servicing income decreased to $76 million during 1998 compared to $138
million during 1997 and $112 million during 1996, representing a decrease of 45%
and a decrease of 32%, respectively. Servicing income declined during 1998 due
to (1) higher amortization of retained interest in securitized assets as a
result of higher credit losses; (2) lower retained interest income as a result
of WFS not executing a securitization transaction in the third quarter and; (3)
increased levels of bankruptcies.
 
     Contractual servicing is earned at a rate of 1.0% to 1.25% per annum on the
outstanding balance of contracts securitized and is consistent with industry
standards. Retained interest income is dependent upon the average excess spread
on the contracts sold and the size of the serviced portfolio. Servicing fee
income is related to the size of the serviced portfolio. During the past three
years, WFS increased its average serviced portfolio to $4.0 billion in 1998 from
$3.4 billion and $2.6 billion in 1997 and 1996, respectively. Other fee income,
consisting primarily of documentation fees, late charges and deferment fees,
decreased to $37.0 million during 1998 compared to $37.1 million and $32.3
million in 1997 and 1996, respectively, representing a decrease of less than 1%
and an increase of 15%, respectively.

     WFS has completed 44 securitization transactions to date since its first
transaction in December 1985. The first eleven of these transactions were on
balance sheet collateralized bond offerings and the remaining 32 were off
balance sheet trusts. Twenty-three transactions have been paid in full and all
were paid on or before their contractual maturity dates.
 
  Net Interest Income
 
     Net interest income is the difference between the rate earned on contracts
held on balance sheet and the interest costs associated with the Company's
borrowings. Net interest income totalled $65.0 million in 1998 compared to $52.7
million and $53.5 million in 1997 and 1996, respectively. The following table
shows the average rate earned on contracts and the average rate paid on
borrowings, consisting primarily of advances from the Bank, together with the
corresponding net interest rate spread for years ended 1998, 1997 and 1996.

</TABLE>
 
     The increase in the net interest rate spread in 1998 was the result of
lower overall financing costs as WFS utilized the line of credit in order to
retain contracts on its balance sheet while obtaining higher yields on those
contracts retained.
 
     As WFS securitizes its contracts, revenue previously recognized as net
interest income will, upon such securitization, be recognized as retained
interest income. Prior to securitizing contracts, WFS earns interest income on
its contracts, pays interest expense to fund the contracts and absorbs any
credit losses. After securitization, the net earnings are recorded as retained
interest income.
 
                                       17
<PAGE>   20
 
     To protect against changes in interest rates, WFS hedges contracts
purchased until their securitization with two-year Treasury securities forward
agreements. The gain or loss on these forward agreements is deferred and
included as part of the basis of the underlying contracts and recognized when
the contracts are securitized. See "Capital Resources and Liquidity".
 
     The Company's primary source of borrowings has been advances from its
parent. These advances were provided on an as-needed basis at a weighted average
rate equal to 7.37% in 1998, 8.16% in 1997 and 6.44% in 1996. For 1998, 1997 and
1996, the cost of borrowings represents the average combined rate of the Senior
Note, Promissory Note and the Line of Credit. See "Capital Resources and
Liquidity" and "Transactions with Related Parties".
 
  Gain on Sale of Contracts
 
     WFS recorded gain on sale of contracts of $25.4 million, $39.4 million and
$41.5 million in 1998, 1997 and 1996, respectively. Gain on sale of contracts
declined compared to prior periods due to not executing a securitization
transaction in the third quarter of 1998, and as a result of changes in the
gross interest rate spread of contracts securitized (see the table under
"Overview"), the amount of dealer participation paid, changes in credit loss
assumptions, and the effect of hedging activities. Gross interest rate spread is
affected by product mix, general market conditions and overall market interest
rates. The risks inherent in interest rate fluctuation are reduced through
hedging activities.
 
     WFS computes a gain on sale with respect to contracts securitized based on
the present value of the estimated future retained interest earnings to be
received from such contracts using a market discount rate. Two methods have
arisen in practice to determine the fair value of these future retained interest
earnings, the cash-in method and the cash-out method. The Securities and
Exchange Commission ("SEC") has set forth specific guidance that the cash-out
method is the only appropriate method to be used in determining the fair value
of such assets as defined by the Financial Accounting Standards Board Statement
No. 125. The cash-out method discounts expected future retained interest
earnings from the period in which the transferor expects to receive the cash,
thereby taking into consideration the period of time that the cash is received
from obligors but restricted from distribution to the transferor. WFS has
historically and will continue to use the cash-out method in measuring such
assets. In order to determine the gain on sale, WFS also considers prepaid
dealer commissions, issuance costs and the effect of hedging activities.
Retained interest in securitized contracts is capitalized upon securitization of
contracts and represents the present value of the estimated future earnings to
be received by WFS from the excess spread created in securitization transactions
and is amortized against servicing income over the life of the contracts. See
"Note 1 -- Summary of Significant Accounting Policies" to WFS' Consolidated
Financial Statements.
 
  Provision for Credit Losses
 
     The Company maintains an allowance for credit losses to cover anticipated
losses on the contracts held on balance sheet. The allowance for credit losses
is increased by charging the provision for credit losses and decreased by actual
losses on the contracts held on balance sheet or as a result of the reduction of
contracts held on balance sheet due to a securitization transaction. The level
of the allowance is based principally on the outstanding balance of contracts
held on balance sheet, pending sales of contracts and historical loss trends.
When WFS sells contracts in a securitization transaction, it reduces its
allowance for credit losses and factors potential losses into its gain on sale
calculation. WFS believes that the allowance for credit losses is currently
adequate to absorb inherent losses in the owned contract portfolio. See "Note
1 -- Summary of Significant Accounting Policies" to WFS' Consolidated Financial
Statements.
 
     During 1998, the provision for credit losses totaled $15.1 million compared
to $8.2 million and $10.3 million in 1997 and 1996, respectively. The increase
in provision for credit losses in 1998 was due primarily to an increased amount
of loans held on balance sheet.

  Operating Expenses
 
     Operating expenses consist of salaries and employee benefits, credit and
collections expense and other miscellaneous costs. Over the past three years,
these expenses have increased as WFS' operations have expanded. At the end of
1994, WFS operated in seven states. Since 1994, WFS has expanded its operations
to include 42 states. As the servicing portfolio increases, costs related to
credit, collection and other related expenses increase as well.
 
     Total operating expenses were $165 million, $167 million and $130 million
for 1998, 1997 and 1996, respectively. The Company reduced its cost of
operations in 1998 in both dollars and as a percent of average serviced
contracts with the completion of the restructuring programs as well as other
operating efficiencies achieved during the year. Operating expenses as a
percentage of average serviced contracts declined 83 basis points to 4.12% in
1998 compared with 4.95% in 1997. Salaries and employee benefit expenses
remained at $95.7 million in both 1998 and 1997, up from $71.9 million in 1996.
Miscellaneous expenses, which includes occupancy, telephone and other
miscellaneous expenses, were $48.1 million, down 16% and 3% from $57.2 million
and $49.4 million in 1997 and 1996, respectively.
 
     WFS pays a monthly management fee to the Bank and Westcorp which covers
various expenses, including accounting, legal, tax, cash management, purchasing
and auditing services. Additionally, the Bank and Westcorp pay fees to WFS for
information services. The management fee is based upon the actual costs incurred
and estimates of actual usage. WFS believes that the management fee approximates
the cost to perform these services on its own behalf or to acquire them from
third parties. WFS has the option, under the management agreements, to procure
these services on its own should it be more economically beneficial to WFS to do
so. See "Transactions with Related Parties -- Management Agreements".
 
  Restructuring
 
     In 1998, the Company completed a restructuring plan initially announced on
February 10, 1998. The plan had four objectives: to reduce operating costs, to
increase contract production volume, to strengthen credit quality and to improve
the quality of personnel. The plan was achieved in two phases. Phase I of the
plan, completed in the first quarter of 1998, consisted of the restructuring of
operations in the Western United States. Phase II of the plan, completed in the
third quarter of 1998 and patterned after Phase I, consisted of the
restructuring of operations in the Central and Eastern United States.
 
     As a result of the restructuring, a total of 400 positions, or 19% of the
Company's workforce, were eliminated and 96 offices were closed. The Company now
purchases contracts through 21 regional business centers (RBCs) and 26 satellite
offices, each offering the full spectrum of prime and non-prime products. The
total pre-tax restructuring charge in 1998 for the completed plan was $15.0
million. Restructuring related costs included $1.8 million for employee
severance and $13.2 million for lease termination fees and the write off of
disposed assets. The restructuring charge was substantially utilized during
1998. Operating costs as a percent of serviced contracts has declined from 5.4%
in 1997 to 3.8% in 1998, resulting in a decrease in operating costs of $65
million on an annual run rate basis.
 
     Through the restructuring, WFS increased its contract production volume to
$2.7 billion compared with $2.3 billion in 1997. Prior to the restructuring, the
Company purchased contracts in 143 offices, each serving either the prime or
non-prime market. As part of the restructuring, the Company closed poorly
performing offices and combined its prime and non-prime marketing into a single,
unified marketing effort. By combining the marketing of the two products under a
single marketing force, WFS is able to more fully leverage its existing dealer
relationships across the full spectrum of credit.
 
     Each of the 47 offices underwrites contracts by employing separate credit
analysts that specialize in either reviewing prime or non-prime paper. The
underwriting process is further enhanced by credit policies and contract
approval authorities controlled by the front-end contract production system and
through the use of the Company's proprietary scorecard which was implemented in
the fourth quarter of 1998. See "Business -- Maintain Solid Asset
Quality -- Consistent and Expeditious Underwriting."
 
                                       19
<PAGE>   22
 
     As part of the restructuring, early delinquency collection efforts were
centralized at two national servicing centers that employ automated queuing and
dialing techniques to contact customers. When these efforts are unsuccessful,
the collection process is transferred to the RBCs where loan service counselors
undertake more extensive collection efforts up to and including repossession.
The Company plans to further improve its collection efforts by implementing a
new collection system, including risk-based collections, in 1999.
 
     During 1998, the Company also established a more effective management
structure. Each RBC is managed by a RBC manager who directs and is responsible
for the performance of the region. Four functional managers who oversee
marketing, credit, collections and operations report directly to the RBC
manager. This organization is designed to provide overall coordination of the
activities within the RBC with appropriate focus and specialization in each of
these four critical business areas. Each of these critical functions also has a
national director who provides expertise, training and policy development,
management and enforcement. This matrix structure has been effective in
providing greater oversight, compliance and focus for each aspect of the
organization and has helped standardize operating practices by identifying best
practices and employing these practices throughout the organization.
 
  Income Taxes
 
     WFS files federal and certain state tax returns as part of a consolidated
group that includes the Bank and Westcorp, the holding company parent of the
Bank. Other state tax returns are filed by WFS as a separate entity. Tax
liabilities from the consolidated returns are allocated in accordance with a tax
sharing agreement based on the relative income or loss of each entity on a
stand-alone basis. The effective tax rate for WFS was 42% for 1998, 1997 and
1996. See "Transactions with Related Parties -- Tax Sharing Agreement".
 
FINANCIAL CONDITION
 
  Contracts Receivable and Contracts Held for Sale
 
     WFS holds a portfolio of contracts on balance sheet for investment that
totaled $70.8 million at December 31, 1998 and $52.6 million at December 31,
1997. Contracts held for sale totaled $825 million at December 31, 1998 compared
to $184 million at December 31, 1997. The balance in the held for sale portfolio
is largely dependent upon the timing of the origination and securitization of
contracts. WFS completed securitization transactions of $1.9 billion during
1998, down from $2.2 billion in 1997 as a result of the Company's decision not
to execute a securitization transaction in the third quarter, during a time when
asset-backed transactions were adversely affected by wider spreads thereby
leaving a greater amount of automobile contracts on the balance sheet. WFS
securitized $1.0 billion of contracts in February 1999, and plans to continue to
securitize contracts on a regular basis when favorable market conditions exist.
See "Note 1 -- Summary of Significant Accounting Policies" to WFS' Consolidated
Financial Statements.
 
  Amounts Due From Trusts
 
     The excess cash flow generated by contracts sold to trusts is deposited
into spread accounts by the trustee under the terms of the securitization
transactions. In addition, at the time a securitization transaction closes, WFS
advances additional monies to WFAL to initially fund these spread accounts. WFS
establishes a liability associated with its use of the spread account funds
which is reduced as such funds reach predetermined funding levels. WFS is
released from obligation after the spread account reaches a predetermined
funding level. Amounts due from trusts represents amounts due to WFS that are
still under obligation to be held in the spread accounts. The amounts due from
trusts at December 31, 1998 was $333 million compared with $295 million at
December 31, 1997. The increase is a result of the increase in total contracts
securitized and outstanding. See "Transactions with Related Parties -- WFS
Reinvestment Contract".
 
  Retained Interest in Securitized Assets
 
     Effective January 1, 1997, the Company adopted Statement of Financial
Accounting Standards No. 125 ("SFAS 125"), "Accounting for Transfers and
Servicing of Financial Assets and Extinguishments of Liabilities". SFAS 125
requires that, following a transfer of financial assets, the transferor
recognizes the
 
                                       20
<PAGE>   23
 
assets it controls and the liabilities it has incurred, and derecognizes assets
for which control has been surrendered and liabilities that have been
extinguished. For securitization transactions, SFAS 125 defines two separate
financial assets retained at the time of securitization, a retained interest in
securitized assets, which represents the excess spread created from
securitization, and a servicing rights asset which represents the benefit
derived from retaining the rights to service the contracts securitized. Previous
accounting guidance did not separately distinguish these rights.
 
     Retained interests in securitized assets ("RISA") capitalized upon
securitization of contracts represent the present value of the estimated future
earnings to be received by WFS from the excess spread created in securitization
transactions. Excess spread is calculated by taking the difference between the
coupon rate of the contracts sold and the certificate rate paid to the investors
less contractually specified servicing and guarantor fees.
 
     Prepayment and credit loss assumptions are utilized to project future
excess spread and are based upon historical experience. Credit losses are
estimated using a cumulative loss rate estimated by management to reduce the
likelihood of asset impairment. All assumptions used are evaluated each quarter
and adjusted, if appropriate, to reflect actual performance of the contracts.
 
     Future earnings are discounted at a rate management believes to be
representative of the market at the time of securitization. The balance of the
RISA is amortized against actual excess spread income earned on a monthly basis
over the expected repayment life of the underlying contracts. RISA's are
classified in a manner similar to available for sale securities and as such are
marked to market each quarter. Market value changes are calculated by
discounting the excess spread using a current market discount rate. Any changes
in the market value of the RISA is reported as a separate component of other
comprehensive income (loss) on the Consolidated Statement of Income (loss) and
Comprehensive Income (loss) and shareholders' equity on the Consolidated
Statements of Financial Condition as an unrealized gain or loss, net of
applicable taxes.
 
     Two methods have arisen in practice to determine the fair value of future
retained interest earnings, the cash-in method and the cash-out method. The
Securities and Exchange Commission ("SEC") has set forth specific guidance that
the cash-out method is the only appropriate method to be used in determining the
fair value of such assets as defined by the Financial Accounting Standards Board
Statement No. 125. The cash-out method discounts future retained interest
earnings from the period in which the transferor expects to receive the cash,
thereby taking into consideration the period of time that the cash is received
from obligors but restricted from distribution to the transferor. WFS has
historically and will continue to use the cash-out method in measuring such
assets.
 
     WFS retains the rights to service all contracts it securitizes. Consumer
servicing rights assets ("CSRA") represent the present value of the estimated
future earnings to be received from servicing securitized contracts. These
earnings are calculated by estimating future servicing revenues, including
contractually specified servicing fees, late charges, other ancillary income,
and float benefit and netting them against the actual cost to service contracts.
WFS has not capitalized any servicing rights as of December 31, 1998.

     At the time of a securitization, the Company utilizes prepayment speed, net
credit loss and discount rate assumptions to initially compute the value of the
RISA. These assumptions may change periodically based on actual performance or

computing RISA. Cumulative net credit loss assumptions utilized for 1998
securitizations ranged from 6% to 7%. The Company used a discount rate of 425
basis points over the two-year Treasury rate at the time of securitization in
discounting future earnings.
 
     The following table presents the estimated future undiscounted retained
interest earnings to be received from securitizations. Estimated future
undiscounted RISA earnings are calculated by taking the difference between the
coupon rate of the contracts sold and the certificate rate paid to the
investors, less the contractually specified servicing fee and guarantor fees,
after giving effect to estimated prepayments and assuming no losses. To arrive
at the RISA, this amount is reduced by the off balance sheet allowance
established for potential future losses and by discounting to present value.

</TABLE>
 
     The decline in the off balance sheet allowance is due to lower potential
future losses as a result of a higher percentage of prime contracts securitized.
WFS believes that the off balance sheet allowance for losses is currently
adequate to absorb potential losses in the sold portfolio.

  Asset Quality
 
     Servicing income is affected by the quality of the underlying contracts
purchased and securitized by WFS. Servicing contracts includes payment
processing, customer service, managing delinquent contracts, repossessing and
selling autos, securing defaulted contracts and recovering deficiency balances.
At December 31, 1998, delinquencies for the serviced portfolio was 3.64% based
on the dollar amount of contracts outstanding compared to 2.20% and 1.80% at
December 31, 1997 and 1996. Delinquency is calculated based on the contractual
due date. Net chargeoffs on average contracts outstanding during the period
totaled 3.42% at December 31, 1998 compared to 3.02% and 2.30% at December 31,
1997 and 1996, respectively. WFS believes the increase in delinquency and loss
experience is due to the shift in product mix from prime to non-prime contracts
in 1996 and 1997, the disruption in collection efforts during the current year
restructurings, and higher than expected bankruptcies. See "Business -- Maintain
Solid Asset Quality".
 
     The following tables reflect the delinquency, repossession and loss
experience that WFS has achieved as a result of its collection efforts. It is
the Company's policy to charge off all contracts once they become 120 days past
due, including those that are not in compliance with a court ordered bankruptcy
plan and whether or not the automobile has been repossessed or sold by that
date. WFS continues to accrue interest on a contract until it is charged off. At
the time a contract is charged off, all accrued but unpaid interest which has
been previously included as income is reversed. No assurance can be given that
the future performance of the contracts purchased by the Company will be similar
to the delinquency, repossession and loss rates disclosed in the following
tables.

- ---------------
(1) Includes contract loss information relating to contracts which are owned by
    WFS and contracts which have been sold and securitized but are serviced by
    WFS.
 
     Delinquency and loss experience was impacted by the disruption in
collection efforts during the current year restructurings, (see "Improve
Operating Efficiencies"), the shift to a greater ratio of non-prime paper during
1996 and 1997, and higher levels of bankruptcies.
 
CAPITAL RESOURCES AND LIQUIDITY
 
     WFS requires substantial capital resources to support its business. The
primary cash requirements related to operating activities include (i) amounts
needed to purchase contracts, (ii) dealer participation, (iii) securitization
costs including spread account advances, and (iv) interest advances to trusts.
WFS also uses significant amounts of cash for operating. Sources of cash
available to WFS include contract securitizations, borrowings under the Line of
Credit and Notes payable and collections of principal and interest from
contracts. These sources provide the liquidity needed to fund the purchase of
contracts.
 
     Although WFS does not have publicly rated debt, its parent, the Bank,
receives long term deposit and subordinated debt ratings. In November 1998,
Moody's downgraded the long term deposit (to Ba3 from Ba2), issuer (to B1 from
Ba3) and subordinated debt (to B2 from B1) ratings of the Bank. This downgrade
could result in higher future financing costs for WFS.
 
                                       26
<PAGE>   29
 
PRINCIPAL USES OF CASH
 
  Purchase of Contracts
 
     The most significant cash flow requirement is for the purchase of
contracts. WFS primarily uses the Line of Credit with the Bank, to fund its
purchase of contracts from dealers and consumers, which are held for sale until
securitized. WFS purchased $2.7 billion of contracts during 1998 compared to
$2.3 billion in 1997 and $2.1 billion in 1996.
 
  Dealer Participation
 
     Consistent with industry practice, WFS pays an up-front dealer
participation to the originating dealer for each contract purchased.
Participation paid by the Company to dealers during 1998 was $76.7 million
compared to $68.0 million in 1997 and $68.6 million in 1996.
 
  Contract Securitizations
 
     At the time a securitization transaction closes, the Company is required to
advance monies to initially fund spread accounts. The Company funds these spread
accounts by foregoing receipt of excess cash flow until these accounts exceed
predetermined levels. The amounts due from trusts represent funds due to the
Company which have not yet been disbursed from the spread accounts. The amounts
due from trusts at December 31, 1998 , including initial advances not yet
returned, was $333 million compared to $295 million at December 31, 1997. See
"Transactions with Related Parties -- Reinvestment Contract".
 
  Advances Due to Servicer
 
     As the servicer of contracts sold in securitizations and in accordance with
servicing agreements, WFS periodically makes advances to the securitization
trusts to provide for temporary delays in the receipt of required payments from
obligors. WFS receives reimbursement of these advances through payments from the
obligor on the contracts or from the trustee at the time a contract liquidates.
 
PRINCIPAL SOURCES OF CASH
 
  Contract Securitizations
 
     The primary source of funds for WFS is the securitization of contracts. WFS
has regularly securitized contracts through underwritten public sales of
securities since 1985. Although the underlying interest costs associated with
securitizations fluctuate, they are primarily market driven and not necessarily
related to the operations of WFS. WFS expects to continue to utilize
securitization transactions as part of its liquidity strategy when the
appropriate market conditions exist.
 
  Other Sources
 
     WFS also obtains cash under the Senior Note, Promissory Note, Line of
Credit, WFS Reinvestment Contract and Short Term Investment from its parent, the
Bank. See "Business -- Transactions with Related Parties'
 
     These financing sources, provided through our parent Company, are expected
to provide adequate funding of the Company's operations, and while no assurances
can be given, the Company believes that its sources of liquidity are sufficient
to meet its long and short term cash requirements.
 
ASSET/LIABILITY MANAGEMENT
 
     Asset/liability management is the process of measuring and controlling
interest rate risk through matching the maturity and repricing characteristics
of interest earning assets with those of interest bearing liabilities.
 
     The contracts originated and held by WFS are all fixed rate and accordingly
WFS has exposure to changes in interest rates. WFS' prepayment experience on
contracts has not been historically sensitive to
 
                                       27
<PAGE>   30
 
changes in interest rates and WFS therefore believes it is not exposed to
significant prepayment risk relative to changes in interest rates. As a result
of this approach to interest rate management, combined with the Company's
hedging strategies, WFS does not anticipate that changes in interest rates will
materially affect the Company's results of operations or liquidity, although no
assurance can be given in this regard.
 
     The Company's hedging strategy includes the use of two-year Treasury
securities forward agreements. Generally, these agreements are entered into by
the Company in amounts which correspond to the principal amount of the
securitization transactions. The market value of these forward agreements is
designed to respond inversely to the market value changes of the underlying
contracts. Because of this inverse relationship, WFS can effectively lock in its
gross interest rate spread at the time of entering into the hedge transaction.
Gains and losses relative to these agreements are deferred and recognized in
full at the time of securitization as an adjustment to the gain or loss on the
sale of the contracts. WFS enters into these forward agreements either with the
Bank or highly rated counterparties and further reduces its risk by avoiding any
material concentration with a single counterparty. Credit exposure is limited to
those agreements with a positive fair value and only to the extent of that fair
value. WFS hedges substantially all of its contracts pending securitization. See
"Note 14 -- Financial Instrument Agreements" to WFS' Consolidated Financial
Statements.
 
     Management monitors the Company's hedging activities to ensure that the
value of hedges, their correlation to the contracts being hedged and the amounts
being hedged continue to provide effective protection against interest rate
risk. The amount and timing of hedging transactions are determined by senior
management of WFS based upon the monitoring activities of the Company. WFS
hedges substantially all of its contracts pending securitization either through
outside parties or affiliated entities.
 
YEAR 2000
 
     During 1997, the Company began a formal risk evaluation of potential Year
2000 issues. The Year 2000 issues arose because many existing computer programs
use only the last two digits to refer to a year. Therefore, these computer
programs do not properly recognize a year that begins with "20" instead of the
familiar "19". If not corrected, many computer applications could fail and
create erroneous results. The outcome of the risk evaluation was the formation
of a Year 2000 Committee that consists of officers and employees of the Company.
In addition, there is a committee that consists of directors that provide
oversight and direction to the Year 2000 Committee. The purpose of the Year 2000
Committee is to assess all risks, analyze current systems, coordinate upgrades
and replacements, and report current and projected status of all known Year 2000
compliance issues.
 
     As a subsidiary of a federally chartered savings bank, WFS is subject to
supervision and regulation by the Office of Thrift Supervision ("OTS"). As such,
WFS and the Bank's compliance to Year 2000 issues are subject to the examination
of the OTS.
 
     The Company has initiated a five-phase program to address the issues
related to the Year 2000 and the impact on the Company's information and
non-information technology systems. In addition, as part of the program, the
Company is in contact with its principal vendors to assess whether their Year
2000 issues, if any, will affect the Company.
 
     The Company, in phase one, identified Year 2000 issues and created a plan.
In phase two, the Company took inventory of the systems and programs affected by
the Year 2000 issues. Currently, the Company is in the third, fourth and fifth
phases of its Year 2000 plan. In these phases, the Company ensures that the
systems have been fixed and tested. It is expected that the third and fourth
phases be completed by March 1999. The final phase implements the tested Year
2000 compliant systems. For some applications, this phase has begun. The Company
expects to have all applications implemented by June 30, 1999.
 
     The Company's replacement or remedied costs for Year 2000 compliance issues
is estimated at approximately $0.9 million, which the Company will expense as
incurred. This estimated cost consists primarily of software upgrades that
include new features which are combined with Year 2000 corrections. The
Company's inception to date Year 2000 cost is approximately $0.5 million.
 
                                       28
<PAGE>   31
 
     Due to the uncertainty and the lack of current disclosure by the electrical
utility industry regarding the progress toward becoming Year 2000 compliant, the
company estimates that the worst case Year 2000 issue scenario would be a
possible discontinuance of electrical power. In the event of an electrical power
failure, the Company has the capability to run its information systems at the
corporate location on diesel powered generators. There is no guarantee, however,
that all issues will be foreseen and corrected, or that no material disruption
of our business will occur.

     Unlike many industrial companies, substantially all of the assets and
liabilities of WFS are monetary in nature. As a result, interest rates have a
more significant effect on WFS' performance than the general level of inflation.
See "Asset/Liability Management".
 
CURRENT ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the FASB issued "SFAS No. 130, Reporting Comprehensive
Income". This statement is effective with the year-end 1998 financial
statements; however, a total for comprehensive income is required in the
financial statements of interim periods beginning with the first quarter of
1998. Reclassification of financial statements for earlier periods provided for
comparative purposes is required. This Statement establishes standards for
reporting and displaying comprehensive income and its components in the
financial statements. It requires that a company classify items of other
comprehensive income, as defined by accounting standards, by their nature (e.g.,
unrealized gains or losses on securities available for sale and retained
interests in securitized assets) in a financial statement with the same
prominence as other financial statements, but does not require a specific format
for that statement. The accumulated balance of comprehensive income is to be
displayed separately from retained earnings and additional paid-in capital in
the equity section of the consolidated statements of financial condition.
 
     In June 1998 the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" (SFAS
133"). This statement provides guidance for the way public enterprises report
information about derivatives and hedging in annual financial statements and in
interim financial reports. The derivatives and hedging disclosure is required
for financial statements for fiscal years beginning after June 15, 1999. The
Statement will require WFS to recognize all derivatives on the balance sheet at
fair value. Derivatives that are not hedges must by adjusted to fair value
through income. If the derivative is a hedge, depending on the nature of the
hedge, changes in fair value of derivatives will either be offset against the
change in fair value of the hedged assets, liabilities, or firm commitments
through earnings or recognized in earnings. The ineffective portion of a
derivative's change in fair value will be immediately recognized in earnings.
WFS is in the process of evaluating the effect SFAS 133 will have, if any, on
the earnings and financial position of the Company.
 
FORWARD-LOOKING STATEMENTS
 
     Included in our Management's Discussion and Analysis of Financial Condition
and Results of Operations section of this Annual Report on Form 10-K are several
"forward-looking statements." Forward-looking statements are those which use
words such as "believe", "expect", "anticipate", "intend", "plan", "may",
"will", "should", "estimate", "continue" or other comparable expression. These
words indicate future events and trends. Forward-looking statements are our
current views with respect to future even and financial performance. These
forward-looking statement are subject to many risks and uncertainties which
could cause actual results to differ significantly from historical results or
from those anticipated by us. The most significant risks and uncertainties we
face are:
 
     1. the level of charge-offs, as an increase in the level of charge-offs
        will decrease our earnings;
 
     2. our ability to originate new contracts in a sufficient amount to reach
        our needs, as a decrease in the amount of contracts we originate will
        decrease our earnings;
 
                                       29
<PAGE>   32
 
     3. a decrease in the difference between the average interest rate we
        receive on the contracts we originate and the rate of interest we must
        pay to fund our cost of originating those contracts; as a decrease will
        reduce our earnings;
 
     4. the continued availability of sources of funding for our operations, as
        a reduction in the availability of funding will reduce our ability to
        originate contracts;
 
     5. maintaining the level of operating costs; as an increase in those costs
        will reduce our net earnings; and
 
     6. the Year 2000 issues; as a disruption of our collection efforts as a
        result of Year 2000 problems or an increase in our costs to correct Year
        2000 issues will reduce earnings.
 
     There are other risks and uncertainties we face, including the effect of
changes in general economic conditions and the effect of new laws, regulations
and court decisions. You are cautioned not to place undue reliance on our
forward-looking statements. We undertake no obligation to publicly update or
revise any forward-looking statements, whether as a result of new information,
future events or otherwise.
 
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
 
     Credit risk and interest rate risk are the primary risks facing the
Company. The Company relies upon sound underwriting practices, credit scoring
and adequate loan loss reserves in order to address credit risk (see
Management's Discussion and Analysis of Financial Condition and Results of
Operation -- Asset Quality).
 
     The Company's Asset/Liability committee is responsible for the management
of interest rate risk. This committee closely monitors interest rate risk and
recommends policy for managing this risk. The primary measurement tool for
evaluating this risk is the use of interest rate shock analysis. It should be
noted that shock analysis is objective but not entirely realistic in that it
assumes an instantaneous and isolated set of events.
 
     Contracts originated and held by WFS are all fixed rate and accordingly
have exposure to changes in interest rates. WFS prepayment experience on
contracts has not been historically sensitive to changes in interest rates and
WFS, therefore, believes it is not expected to be exposed to significant
prepayment risk relative to changes in interest rates.
 
     The Company's hedging strategy includes the use of two-year Treasury
securities forward agreements. Generally, these agreements are entered into by
the Company in amounts which correspond to the principal amount of the
securitization transactions. The market value of these forward agreements is
designed to respond inversely to the market value changes of the underlying
contracts. Because of this inverse relationship, WFS can effectively lock in its
gross interest rate spread at the time of entering into the hedge transaction.
Gains and losses relative to these agreements are deferred and recognized in
full at the time of securitization as an adjustment to the gain or loss on the
sale of the contracts. WFS enters into these forward agreements either with the
Bank or highly rated counterparties and further reduces its risk by avoiding any
material concentration with a single counterparty.
 
     Management monitors the Company's hedging activities to ensure that the
value of hedges, their correlation to the contracts being hedged and the amounts
being hedged continue to provide effective protection against interest rate
risk. The amount and timing of hedging transactions are determined by senior
management of WFS based upon the monitoring activities of the Company.
 
     As a result of this approach to interest rate management, combined with the
Company's hedging strategies, WFS does not anticipate that changes in interest
rate will materially affect the Company's results of operations or liquidity,
although no assurance can be given in this regard.
 
     The following table provides information about the Company's derivative
financial instruments and other financial instruments used that are sensitive to
changes in interest rates. For loans and liabilities with contractual
maturities, the table presents principal cash flows and related weighted average
interest rates by

contractual maturities as well as the Company's historical experience of the
impact of interest rate fluctuations on the prepayment of contracts.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
WFS Financial Inc
 
     We have audited the accompanying consolidated statements of financial
condition of WFS Financial Inc and subsidiaries as of December 31, 1998 and
1997, and the related consolidated statements of operations, shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1998. These consolidated financial statements are the responsibility of WFS
Financial Inc's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly
in all material respects, the consolidated financial position of WFS Financial
Inc and subsidiaries at December 31, 1998 and 1997 and the consolidated results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1998, in conformity with generally accepted accounting
principles.

                       WFS FINANCIAL INC AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1998
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Basis of Presentation: The accompanying consolidated financial statements
include the accounts of WFS Financial Inc ("WFS") and its subsidiaries, WFS
Financial Auto Loans, Inc. ("WFAL"), WFS Financial Auto Loans 2, Inc. ("WFAL2")
and WFS Investments, Inc. ("WFSII"). All significant intercompany transactions
and accounts have been eliminated in consolidation. Certain amounts have been
reclassified to conform to the 1998 presentation. After the initial public
offering on August 8, 1995, WFS became a majority owned subsidiary of Western
Financial Bank ("the Bank"), which is a wholly owned subsidiary of Westcorp.
 
     WFS pays a monthly management fee to the Bank and Westcorp which covers
various expenses, including accounting, legal, tax, cash management, purchasing
and auditing services. Additionally, the Bank and Westcorp pay a fee to WFS for
information services. The management fee is based upon the actual costs incurred
and estimates of actual usage. WFS believes that the management fee approximates
the cost to perform these services on its own behalf or to acquire them from
third parties. WFS has the option, under the management agreements, to procure
these services on its own should it be more economically beneficial to WFS to do
so.
 
     Use of Estimates: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
     Nature of Operations: WFS is a consumer finance company that specializes in
the purchase, securitization and service of fixed rate consumer auto loans
("contracts"). WFS purchases contracts from franchised new and independent used
car dealers on a nonrecourse basis and originates loans directly with consumers
which are collectively known as contracts. WFS purchased contracts in 42 states
from over 11,000 dealers.
 
     Cash and Cash Equivalents: Cash and cash equivalents includes short term
investments with the Bank. There are no material restrictions as to the
withdrawal or usage of this amount.
 
     Allowance for Credit Losses: The allowance for credit losses is maintained
at a level believed adequate by management to absorb inherent losses in the on
balance sheet contract portfolio. Management's determination of the adequacy of
the allowance is based on an evaluation of the portfolio, past contract loss
experience, current economic conditions, volume, pending contract sales, growth
and composition of the contract portfolio, and other relevant factors. The
allowance is increased by provisions for credit losses charged against income.
 
     Sales of Contracts: Contracts are originated and sold to investors with
servicing rights retained by WFS. WFS does not retain any recourse with respect
to the contracts securitized. As part of the sale, the trustee reimburses the
Company for borrowing costs incurred between the cut-off date of the loans and
the closing date of the sale.
 
     Gain on sale of contracts represents the present value of the estimated
future earnings to be received from the excess spread created in the
securitization transactions less prepaid dealer participations, issuance costs,
and the effect of hedging activities. These retained interest in securitized
assets ("RISA") are capitalized and amortized over the expected repayment life
of the underlying contracts. WFS utilizes the cash-out method in determining the
valuation of the RISA.
 
     WFS evaluates quarterly the carrying value of its RISA in light of the
actual repayment experience of the underlying contracts and makes adjustments to
reduce the carrying value, if appropriate. Servicing income and amortization of
RISA are included in servicing income in the Consolidated Statements of
Operations.

                       WFS FINANCIAL INC AND SUBSIDIARIES
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1998
 
     As servicer of these contracts, WFS holds and remits funds collected from
the borrowers on behalf of the trustee pursuant to a reinvestment contract that
WFS has entered into with the Bank. These amounts are reported as amounts held
on behalf of trustee. WFS retains servicing rights and is entitled to servicing
income. Amounts due from trusts represents servicing income earned by WFS for
which WFS has not yet received repayment from the trust.
 
     Nonaccrual Contracts: WFS continues to accrue interest income on contracts
until the contract is charged off, which occurs automatically after the contract
is contractually past due 120 days. At the time that the contract is charged
off, all accrued interest is also reversed.
 
     Contracts Held for Sale: Contracts held for sale are stated at the lower of
aggregate amortized cost or market. The carrying amount of the specific contract
pool sold is used to compute gains or losses. Market value is based on
discounted cash flow calculations, which approximates the amounts realized upon
securitization of the contracts.
 
     WFS' hedging strategy includes the use of two-year Treasury securities
forward agreements. These agreements are entered into by the Company in numbers
and amounts which generally correspond to the principal amount of the
securitization transactions. The market value of these forward agreements
responds inversely to the market value changes of the underlying contracts.
Because of this inverse relationship, WFS can effectively lock in its gross
interest rate spread at the time of the hedge transaction. Gains and losses
relative to these agreements are deferred and recognized in full at the time of
securitization as an adjustment to the gain or loss on the sale of the
contracts. WFS uses only highly rated counterparties and further reduces its
risk by avoiding any material concentration with a single counterparty. Credit
exposure is limited to those agreements with a positive fair value and only to
the extent of that fair value.
 
     Property, Plant and Equipment: Property, plant and equipment are recorded
at cost less accumulated depreciation and amortization and are depreciated over
their estimated useful lives principally using the straight line method for
financial reporting and accelerated methods for tax purposes. Leasehold
improvements are amortized over the lives of the respective leases or the
service lives of the improvements, whichever is shorter.
 
     Interest Income and Fee Income: Interest income is earned in accordance
with the terms of the contracts. For pre-computed contracts, interest is earned
monthly and for simple interest contracts, interest is earned daily. Interest
income on certain contracts is earned using the effective yield method and
classified on the balance sheet as interest receivable to the extent not
collected. Other contracts use the sum of the months digits method, which
approximates the effective yield method.
 
     WFS defers contract origination fees and premiums paid to dealers. The net
amount is amortized as an adjustment to the related contract's yield, over the
contractual life of the related contract or until the contract is sold at which
time any remaining amounts are included as part of the gain on sale of
contracts. Fees for other services are recorded as income when earned.
 
     Stock Options: Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" ("SFAS 123"), provides for companies
to recognize compensation expense associated with stock-based compensation plans
over the anticipated service period based on the fair value of the award on the
date of grant. However, SFAS 123 allows companies to continue to measure
compensation costs prescribed by Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB 25"). Companies electing to
continue accounting for stock-based compensation plans under APB 25 must make
pro forma disclosures of net income and earnings per share as if SFAS 123 has
been adopted, if the fair value of the options has a material impact on
earnings. WFS has continued to account for stock-based compensation plans under
APB 25. The impact of applying SFAS 123 in 1998, 1997 and 1996 is immaterial to
the financial statements of WFS.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1998
 
     Income Taxes: WFS files consolidated federal and state tax returns as part
of a consolidated group that includes the Bank and Westcorp. WFS taxes are paid
in accordance with a tax sharing agreement that allocates taxes based on the
relative income or loss of each entity on a stand-alone basis.
 
     Fair Value of Financial Instruments: Fair value information about financial
instruments whether or not recognized in the balance sheet, for which it is
practicable to estimate that value, are reported using quoted market prices. In
cases where quoted market prices are not available, fair values are based on
estimates using present value or other valuation techniques. Those techniques
are significantly affected by the assumptions used, including the discount rate
and estimates of future cash flows. In that regard, the derived fair value
estimates cannot be substantiated by comparison to independent markets and in
many cases, could not be realized in immediate settlement of the instrument.
Fair values for certain financial instruments and all non-financial instruments
are not required to be disclosed. Accordingly, the aggregate fair value of
amounts presented do not represent the underlying value of WFS.
 
     WFS' financial instruments as defined by Statement of Financial Accounting
Standards No. 107, "Disclosures About Fair Value of Financial Instruments,"
including short term investments, retained interest in securitized assets and
amounts held on behalf of trustee are accounted for on a historical cost basis
which , due to the nature of these financial instruments, approximates fair
value. The fair value for contracts receivable is based on quoted market prices
of similar contracts sold in conjunction with securitization transactions,
adjusted for differences in contract characteristics. The fair value of forward
agreements is estimated by obtaining market quotes from brokers. The fair value
of notes payable -- parent is estimated using discounted cash flow analysis,
based on current borrowing rates for similar instruments.
 
     In June 1997, the FASB issued "SFAS No. 130, Reporting Comprehensive
Income". This statement is effective with the year-end 1998 financial
statements; however, a total for comprehensive income is required in the
financial statements of interim periods beginning with the first quarter of
1998. Reclassification of financial statements for earlier periods provided for
comparative purposes is required. This Statement establishes standards for
reporting and displaying comprehensive income and its components in the
financial statements. It requires that a company classify items of other
comprehensive income, as defined by accounting standards, by their nature (e.g.,
unrealized gains or losses on securities available for sale and retained
interests in securitized assets) in a financial statement with the same
prominence as other financial statements, but does not require a specific format
for that statement. The accumulated balance of comprehensive income is to be
displayed separately from retained earnings and additional paid-in capital in
the equity section of the consolidated statements of financial condition.
 
     In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" (SFAS
133"). This statement provides guidance for the way public enterprises report
information about derivatives and hedging in annual financial statements and in
interim financial reports. The derivatives and hedging disclosure is required
for financial statements for fiscal years beginning after June 15, 1999. The
Statement will require WFS to recognize all derivatives on the balance sheet at
fair value. Derivatives that are not hedges must be adjusted to fair value
through income. If the derivative is a hedge, depending on the nature of the
hedge, changes in fair value of derivatives will either be offset against the
change in fair value of the hedged assets, liabilities, or firm commitments
through earnings or recognized in earnings. The ineffective portion of a
derivative's change in fair value will be immediately recognized in earnings.
WFS is in the process of evaluating the effect SFAS 133 will have, if any, on
the earnings and financial position of the Company.

NOTE 2 -- NET CONTRACTS RECEIVABLE
 
     WFS' contract portfolio consists of contracts purchased from automobile
dealers on a nonrecourse basis and contracts financed directly with the
consumer. If pre-computed finance charges are added to a contract, they are
added to the contract balance and carried as an offset against the contract
balance as unearned discounts. Amounts paid to dealers are capitalized as dealer
participation and amortized over the life of the contract.
 
     Net contracts receivable consisted of the following:

     The contracts purchased by the Company are fixed-rate loans. The Company
bears the risk of interest-rate increases during the period between the setting
of the rate at which the contract will be acquired and their sale in a
securitization transaction. In order to mitigate this risk, the Company uses
two-year Treasury securities forward agreements to minimize its exposure to
interest rate risk during the relevant period. The fair value of these
instruments may vary with changes in interest rates. Generally, these agreements
are entered into by WFS in amounts which correspond to the principal amount of
the securitization transactions. The market value of these forward agreements is
designed to respond inversely to the market value changes of the underlying
contracts. Because of this inverse relationship, WFS can effectively lock in its
gross interest rate spread at the time of entering into the hedge transaction.
Gains and losses relative to these agreements are deferred and recognized in
full at the time of securitization as an adjustment to the gain or loss on the
sale of the contracts. WFS enters into these forward agreements either with the
Bank, or highly rated counterparties and further reduces its risk by avoiding
any material concentration with a single counterparty. Credit exposure is
limited to those agreements with a positive fair value and only to the extent of
that fair value. WFS hedges substantially all of its contracts pending
securitization.

$3.5 billion at December 31, 1998 and $3.4 billion at December 31, 1997.

NOTE 4 -- RETAINED INTEREST IN SECURITIZED ASSETS
 
     SFAS 125 requires that following a transfer of financial assets, an entity
is to recognize the assets it controls and the liabilities it has incurred, and
derecognizes assets for which control has been surrendered and liabilities that
have been extinguished. For securitization transactions, SFAS 125 defines two
separate financial assets retained at the time of securitization, a retained
interest in securitized assets, which represents the excess spread created from
securitization, and a servicing rights asset which represents the benefit
derived from retaining the rights to service the contracts securitized. Previous
accounting guidance did not separately distinguish these rights.
 
     Retained interests in securitized assets capitalized upon securitization of
contracts represent the present value of the estimated future earnings to be
received by WFS from the excess spread created in securitization transactions.
Excess spread is calculated by taking the difference between the coupon rate of
the contracts sold and the interest rate paid to the investors less
contractually specified servicing and guarantor fees.
 
     Prepayment and credit loss assumptions are utilized to project future
earnings and are based upon historical experience. Credit losses are estimated
using a cumulative loss rate estimated by management to reduce the likelihood of
asset impairment. All assumptions used are evaluated each quarter and adjusted,
if appropriate, to reflect actual performance of the contracts.
 
     Future earnings are discounted at a rate management believes to be
representative of the market at the time of securitization. The balance of the
RISA is amortized against actual excess spread income earned on a monthly basis
over the expected repayment life of the underlying contracts. RISAs are
classified in a manner similar to available for sale securities and as such are
marked to market each quarter. Market value changes are calculated by
discounting the excess spread using a current market discount rate. Any changes
in the market value of the RISA is reported as a separate component of
shareholders' equity as an unrealized gain or loss, net of applicable taxes.
 
     Two methods have arisen in practice to determine the fair value of credit
enhancement assets: the cash-in method and the cash-out method. The Securities
and Exchange Commission ("SEC") has set forth specific guidance that the
cash-out method is the only appropriate method to be used in determining the
fair value of such assets as defined by the SFAS No. 125. The cash-out method
discounts expected cash flows from the period in which the transferor expects to
receive the cash, thereby taking into consideration the period of time that the
cash is received from obligors but restricted from distribution to the
transferor. WFS has historically used the cash-out method in measuring such
assets.
 
     WFS retains the rights to service all contracts it securitizes. Consumer
servicing rights assets ("CSRA") represent the present value of the estimated
future earnings to be received from servicing securitized contracts. These
earnings are calculated by estimating future servicing revenues, including
contractually specified

     At the time of a securitization, the Company utilizes prepayment speed, net
credit loss and discount rate assumptions to initially compute the value of the
RISA. These assumptions may change periodically based on actual performance or
other factors. During 1998, the Company utilized prepayment rates of 1.6% ABS in
computing RISA. Cumulative net credit loss assumptions utilized for 1998
securitizations ranged from 6% to 7%. The Company used a discount rate of 425
basis points over the two-year Treasury rate at the time of securitization in
discounting future earnings.
 
     The following table presents the estimated future undiscounted retained
interest earnings to be received from securitizations. Estimated future
undiscounted RISA earnings are calculated by taking the difference between the
coupon rate of the contracts sold and the certificate rate paid to the
investors, less the contractually specified servicing fee and guarantor fees,
after giving effect to estimated prepayments and assuming no losses. To arrive
at the RISA, this amount is reduced by the off balance sheet allowance
established for potential future losses and by discounting to present value.

NOTE 6 -- INTERCOMPANY AGREEMENTS
 
     In 1995, WFS entered into a Line of Credit agreement and a Senior Note with
the Bank. The Line of Credit agreement permits WFS to draw up to $900 million to
be used in its operations. The Line of Credit terminates on December 31, 1999
although the term may be extended by WFS for additional periods up to 56 months.
When secured by contracts, the first $600 million of the Line of Credit carries
an interest rate equal to the Federal composite commercial paper rate plus 10
basis points, with the margin increasing to 50 basis points to the extent the
obligation is not secured. The next $300 million of the Line of Credit carries
an interest rate equal to the Federal composite commercial paper rate plus 40
basis points when secured by contracts, with the margin increasing to 80 basis
points to the extent the obligation is not secured. The average balance of the
Line of Credit was $278 million and $107 million for 1998 and 1997,
respectively. The weighted average interest rate was 6.04% and 5.70% and the
interest expense was $16.8 million, $6.1 million, and $8.1 for 1998 and 1997 and
1996, respectively. The Line of Credit had $555 million outstanding at December
31, 1998.
 
     WFS also borrowed $125 million from the Bank under the terms of the Senior
Note. The Senior Note provides for principal payments of $25 million per year,
commencing on April 30, 1999 and continuing through its final maturity, April
30, 2003. During 1998, the Company made a paydown of $15.0 million without
prepayment penalties. Interest payments on the Senior Note are due quarterly, in
arrears, calculated at the rate of 7.25% per annum. The Senior Note is not
secured. Pursuant to the terms of the Senior Note, WFS may not incur any other
indebtedness which is senior to the obligations evidenced by the Senior Note
except for (i) indebtedness collateralized or secured under the Line of Credit
and (ii) indebtedness for similar types of warehouse lines of credit. The Senior
Note had interest expense of $9.0 million and $9.1 million for 1998 and 1997,
respectively.
 
     Additionally, WFS borrowed $50 million from the Bank under the terms of the
Promissory Note dated August 1, 1997. The Promissory Note provided for principal
payments in two equal annual installments of $25 million. Subsequent to year
end, the Promissory Note was amended to increase the amount by $30 million and
to provide for principal payments in two equal annual installments of $40
million commencing on July 31,

2001. Interest payments on the Promissory Note are due quarterly, in arrears,
calculated at the rate of 9.42% per annum. Pursuant to the terms of the
Promissory Note, WFS may not incur any other indebtedness which is senior to the
obligations evidenced by the Promissory Note except for (i) indebtedness under
the Senior Note (ii) indebtedness collateralized or secured under the Line of
Credit and (iii) indebtedness for similar types of warehouse lines of credit.
The Promissory Note had interest expense of $4.7 million and $2.0 million during
1998 and 1997, respectively.
 
     WFS also invests its excess cash at the Bank under an Investment Agreement.
The Bank pays WFS an interest rate equal to the Federal composite commercial
paper rate on this excess cash. The weighted average interest rate was 5.45% and
5.78% for 1998 and 1997, respectively. The average balance of the excess cash
was $9.0 million and $30.0 million, and the interest income earned was $0.5
million and $1.7 million during 1998 and 1997, respectively.
 
     WFS has entered into certain management agreements with the Bank and
Westcorp pursuant to which WFS pays its allocated portion of certain costs and
expenses incurred by the Bank and Westcorp with respect to services or
facilities of the Bank and Westcorp used by WFS or its subsidiaries, including
their principal office facilities, field offices of WFS and overhead and
employee benefits pertaining to Bank and Westcorp employees who also provide
services to WFS or its subsidiaries. Additionally, as part of these management
agreements, the Bank and Westcorp have agreed to reimburse WFS for similar costs
incurred. The management agreements may be terminated by any party upon 5 days
prior written notice without cause, or immediately in the event of the other
party's breach of any covenant, obligation, or duty contained in the applicable
management agreement or for violation of law, ordinance, statute, rule or
regulation governing either party to the applicable management agreement.
 
     Pursuant to a series of agreements to which WFS, the Bank and WFAL2, among
others, are parties, WFS is able to access the cash flows of each of the
outstanding securitization transactions and the cash held in each spread account
for each of those transactions. WFS is permitted to use that cash as it
determines, including in its ordinary business activities of originating
contracts.
 
     In each securitization transaction, the Bank and WFAL2 have entered into a
reinvestment contract, which is deemed to be an eligible investment under the
relevant securitization agreements. The securitization agreements require,
provided certain conditions are met, that all cash flows of the relevant trust
and the associated spread accounts be invested in the applicable reinvestment
contract. A limited portion of the invested funds may be used by WFAL2 and the
balance may be used by the Bank. The Bank makes its portion available to WFS
pursuant to the terms of the WFS Reinvestment Contract ("RIC"). Under the
RIC,WFS receives access to all of the cash available to the Bank under each
trust reinvestment contract and is obligated to repay to the Bank an amount
equal to the cash so used when needed by the Bank to meet its obligations under
the individual trust reinvestment contracts. With the portion of the cash
available to it under the individual trust reinvestment contracts, WFAL2
purchases contracts from WFS pursuant to the terms of Sale and Servicing
Agreements.
 
     FSA, the trust reinvestment contracts may be eligible investments provided
the Bank and WFAL2 pledge adequate collateral to secure their respective
obligations. In accordance with this agreement, the Bank and WFAL2 pledge
property owned by each for the benefit of the trustee of each trust and FSA. WFS
pays the Bank a fee equal to 12.5 basis points of the amount of collateral
pledged by the Bank as consideration for the pledge of collateral by the Bank
and for WFS' access to cash under the RIC. During 1998, WFS paid the Bank $0.7
million for this purpose. As WFAL2 directly utilizes the cash made available to
it to purchase contracts for its own account from WFS, no additional
consideration from WFS is required to support WFAL2's pledge of its property
under the agreement with FSA. While WFS is under no obligation to repurchase
contracts from WFAL2 to the extent WFAL2 needs to sell any such contracts to
fund its repayment obligations under the trust reinvestment contracts, it is
anticipated that WFS would prefer to purchase those contracts than for WFAL2 to
sell those contracts to a third party. The RIC, by its terms, is to

eligible investment for its related securitization transaction. During 1998 the
average amount outstanding under the RIC was $585 million and the average amount
of contracts purchased by WFAL2 from WFS was $119 million. At December 31, 1998,
the amount outstanding under the RIC was $364 million and the amount of

amounts paid to Westran in 1998, 1997 and 1996 was $0.2 million, $0.1 million
and $0.4 million, respectively.

NOTE 9 -- EMPLOYEE STOCK OWNERSHIP AND SALARY SAVINGS PLAN
 
     WFS participates in the Westcorp Employee Stock Ownership and Salary
Savings Plan ("the Plan"), which covers essentially all full-time employees who
have completed one year of service. Contributions to the Plan are discretionary
and determined by the Board of Directors of Westcorp within limits set forth
under the

Employee Retirement Income Security Act of 1974. Contributions to the Plan are
fully expensed in the year in which the contribution is made.
 
     Westcorp's contributions to the Plan for all Westcorp employees amounted to
$0.8 million, $2.4 million and $3.4 million in 1998, 1997 and 1996,
respectively.
 
NOTE 10 -- STOCK OPTIONS
 
     In 1996, WFS reserved 550,000 shares of common stock for future issuance to
certain employees under an incentive stock option plan ("the Plan"). In 1997,
WFS reserved an additional 550,000 shares of common stock for future issuance
under the Plan. An additional 130,343 shares of existing options expired during
1998. There were 757,608 shares available for future grants at December 31,
1998. The options may be exercised within five to seven years after the date of
grant. Additionally, the weighted average life of the options at December 31,
1998 was 6.3 years and the exercise price of the options outstanding at December
31, 1998 ranged from $6.94 to $18.00 per share.
 
     At December 31, 1998 there were no exercisable stock options under the
plan. In October 1998 the Company canceled 624,539 of existing options as part
of a voluntary stock option exchange program. All option holders taking part in
this program forfeited their existing options and were issued a proportionately
smaller number of new options based upon a reduced exercise price. Stock option
activity is summarized as follows:

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because WFS' employee stock options have characteristics
significantly different from those traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

     The fair value of options granted in 1998, 1997 and 1996 was estimated at
the date of grant using a Black-Scholes option pricing model with the following
assumptions:

</TABLE>
 
     The weighted average fair value of options per share granted during 1998,
1997 and 1996 was $4.57, $8.26 and $6.82, respectively.
 
     The Company elected to follow APB 25 and related Interpretations in
accounting for its employee stock options. Under APB 25, the exercise price of
the Company's employee stock options equals the market price of the underlying
stock on the date of grant and, therefore, no compensation expense is
recognized. Proforma information regarding net income and earnings per share is
required by SFAS No. 123, and has been determined as if the Company had
accounted for its employee stock option under the fair value method of that
statement. Proforma net income/(loss) and earnings/(loss) per diluted share for
1998, 1997 and 1996 were as follows:

NOTE 11 -- RESTRUCTURING
 
     In 1998, the Company completed a restructuring plan initially announced on
February 10, 1998. The goal of the plan was to consolidate offices and eliminate
redundant staff positions on a national level. The plan was achieved in two
phases. Phase I of the plan, completed in the first quarter of 1998, consisted
of the restructuring of operations in the Western United States. Phase II of the
plan, completed in the third quarter of 1998 and patterned after Phase I,
consisted of the restructuring of operations in the Central and Eastern United
States. As a result of these two restructurings, a total of 400 positions, or
19% of the Company's workforce, were eliminated and 96 offices were closed. The
total pre-tax restructuring charge in 1998 for the completed plan was $15.0
million. Restructuring related costs included $1.8 million for employee
severance and $13.2 million for lease termination fees and the write off of
disposed assets. The restructuring charge was substantially utilized during
1998.
 
     Through the restructuring, WFS merged prime and non-prime office locations
with close geographic proximity and closed poorly performing offices. The
remaining offices now offer its dealer base the full spectrum of prime and
non-prime products through a single sales and marketing force. However, WFS
employs separate credit analysts that specialize in either reviewing prime or
non-prime paper. These analysts provide more consistent underwriting practices
through the use of a proprietary scorecard with its system-enforced credit
requirements which was also implemented during the year.

     Deferred taxes reflect the net tax effects of temporary differences between
the carrying amounts of assets and liabilities for financial reporting purposes
and the amounts used for income tax purposes. Amounts previously reported as
current and deferred income tax expense have been restated. Such changes to the
components of the expense occur because all tax alternatives available to WFS
are not known for a number of months subsequent to year end.

NOTE 14 -- FINANCIAL INSTRUMENT AGREEMENTS
 
     WFS Financial uses Forward Agreements to minimize its exposure to interest
rate risk. The fair value of these instruments may vary with changes in interest
rates. At December 31, 1998, WFS' portfolio consisted of Forward Agreements with
a notional amount of $775 million.
 
     Notional amounts do not represent amounts exchanged with other parties and,
thus are not a measure of WFS' exposure to loss through its use of these
agreements. The amounts exchanged are determined by reference to the notional
amounts and the other terms of the agreements.

NOTE 15 -- EARNINGS PER SHARE
 
     Basic earnings per share is calculated by dividing net income available to
common stockholders by the weighted average number of common shares outstanding
and does not include the impact of any potentially dilutive common stock
equivalents. Diluted earnings per share is arrived at by dividing net income by
the weighted average number of shares outstanding, adjusted for the dilutive
effect of outstanding stock options.
 
     The calculation of net income per common share follows:

     Options to purchase 317,949 and 469,980 shares of common stock at a range
of $6.94 to $18 per share, respectively, were outstanding during 1998 and 1997
but were not included in the computation of diluted earnings per share because
the Company experienced a loss and the options' exercise price was greater than
the average market price of the common shares, and therefore, the effect would
be antidilutive. There were no antidilutive options for 1996.

             AMENDED AND RESTATED MASTER RIC REIMBURSEMENT AGREEMENT


                  THIS AMENDED AND RESTATED MASTER RIC REIMBURSEMENT AGREEMENT
dated as of November 1, 1998 (the "Agreement"), which amends and restates the
Master RIC Reimbursement Agreement dated as of June 1, 1995 (the "Original

its successors and assigns, the "Bank"), WFS FINANCIAL AUTO LOANS 2, INC., a
California corporation (including its successors and assigns, "WFAL 2"), and
FINANCIAL SECURITY ASSURANCE INC., a New York stock insurance company (including
its successors and assigns, "Financial Security").

joint reinvestment contracts dated on or after the date hereof (as amended from
time to time, the "Joint Reinvestment Contracts" or "Joint RICs") comprising
certain of the RICs (as defined below) and (ii) the obligor under certain
reinvestment contracts dated prior to the date hereof (as amended from time to
time, the "Bank Reinvestment Contracts" or "Bank RICs"; and, together with the
Joint RICs, the "RICs" defined in Section 1 hereof.

                  Financial Security has issued financial guaranty insurance
policies guaranteeing payment by the Bank under the Bank RICs on each
Distribution Date. The Bank and WFAL 2 have requested, and may in the future
request, that Financial Security issue financial guaranty insurance policies to
the Trustee of the Trusts (as defined in Section 1 hereof) to guarantee payment
under the Joint RICs on each Distribution Date. The policies referred to in the
preceding two sentences are herein called "RIC Policies".

                  As partial inducement to Financial Security to issue RIC
Policies, the Bank and WFAL 2 intend to enter into this Agreement in order to
secure the obligations of the Bank and WFAL 2 hereunder, and, pursuant to the
Second Amended and Restated Master Collateral Assignment Agreement, to pledge
Collateral to the Master Collateral Agent for the benefit of Financial Security.

                  All parties hereto wish to maintain in force RIC Policies and
other arrangements with respect to the Bank RICs.

If the Aggregate Collateral Value so certified is less than the Aggregate
Commingled Account Balance as so certified, either or both of the Bank and WFAL
2 shall, together with such certificate, Deliver additional Collateral in an
amount necessary to make the Aggregate Collateral Value (after giving effect to
such Delivery) at least equal to the Aggregate Commingled Account Balance.

                  (c) The Master Collateral Agent may release items of

Securities shall be maintained pending its maturity or deposition hereunder,
through continued registration of the ownership of such Security as described in
Clause (iii) of the definition of "Delivery".

                  (f) All Collateral consisting of chattel paper or general
intangibles (including the WFS Sale and Servicing Agreement) shall be duly

credited to the Collateral Account, including any interest or capital gains on
investments, shall be deposited in the Collateral Account. All right, title and
interest in and to the funds on deposit from time to time in the Collateral
Account, together with any investments made pursuant to paragraph (c) below,
shall vest in the Master Collateral Agent, shall constitute part of the
Collateral hereunder and shall not constitute payment of any Master Secured

the Controlling Party; provided that if the Master Collateral Agent receives an
FSA Notice, the Master Collateral Agent shall, if instructed by the Controlling
Party, liquidate any such investments and apply or cause to be applied the
proceeds thereof to the payment of the Master Secured Obligations in the manner
specified in Section 3.03(c) hereof. If no such instruction with respect to
investment of any portion of the Collateral Account is received by the Master
Collateral Agent, no investment shall be made of such portion and the Master
Collateral Agent shall not be liable for any resulting absence of income.

                  (d) On each Business Day specified by the Controlling Party
after delivery of an FSA Notice, the Master Collateral Agent shall withdraw from
the Collateral Account an amount (up to the balance therein) that is sufficient
to pay to Financial Security or the Trustee all amounts constituting Master
Secured Obligations owing to Financial Security or the Trustee, as the case may
be (such payments to be applied to reduce the Master Secured Obligations in such
manner as the Controlling Party shall specify). All amounts or investments, if
any, remaining in the Collateral Account on any date after giving effect to the

relocation) of the Collateral Account hereunder, the Master Collateral Agent

Account was established (if not Bankers Trust Company of California, N.A. or any
successor Master Collateral Agent in its commercial banking capacity), the name
of the officer of the depository institution who is responsible for overseeing
the Collateral Account, the Collateral Account number and the individuals whose
names appear on the signature cards for the Collateral Account. The Bank and
WFAL 2 shall cause such depository institution to execute a written agreement,
in form and substance satisfactory to the Controlling Party, waiving, in each
case to the extent permitted under applicable law, (i) any banker's or other
statutory or similar Lien, and (ii) any right of setoff or other similar right
under applicable law with respect to the Collateral Account and agreeing to
notify the Bank, WFAL 2, the Master Collateral Agent, Financial Security and the
Trustee of any charge or claim against or with respect to the Collateral
Account. The Master Collateral Agent shall give the Bank, WFAL 2, Financial
Security and the Trustee at least ten (10) Business Days' prior written notice
of any change in the location of the Collateral Account or in any related
account information. Anything herein to the contrary notwithstanding, unless
otherwise consented to by the Controlling Party in writing, the Master
Collateral Agent shall have no right to change the location of the Collateral
Account.

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

<PAGE>   15

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

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

         Section 3.05. FSA Notices. The Controlling Party may at any time give
notice (an "FSA Notice") to the Master Collateral Agent stating that (i) a
Default has occurred and is continuing or (ii) the Controlling Party has,
pursuant to any Existing Agreement, terminated the status of a Reinvestment
Contract as an eligible investment under a Trust Agreement or other Existing
Agreement.

         Section 3.06. Representations by the Bank and WFAL 2. The Bank and WFAL
2 hereby jointly and severally represent and warrant to the other parties
hereto, as of the date hereof and as of the Delivery of any Collateral
hereunder, as follows:

Master Collateral Agent will have a valid perfected first priority security
interest in such Collateral.

authorize the Master Collateral Agent to take such action on their behalf, and
to exercise such rights, remedies, powers and privileges hereunder as the
Controlling Party may direct and as are specifically authorized to be exercised
by the Master Collateral Agent by the terms hereof, together with such actions,
rights, remedies, powers and privileges as are reasonably incidental thereto.
The Master Collateral Agent shall execute the Servicing Agreement and shall act
upon and in compliance with the written instructions of the Controlling Party
delivered pursuant to this Agreement promptly following receipt of such written
instructions.

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

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

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

         Section 4.03. Limitation on Liability; Indemnification. Neither the
Master Collateral Agent nor any of its directors, officers or employees, shall
be liable for any action taken or omitted to be taken by it or them hereunder,
or in connection herewith, except that the Master Collateral Agent shall be
liable for its own gross negligence or willful misconduct; nor shall the Master
Collateral Agent be responsible for the validity, effectiveness, value,
sufficiency or enforceability against the Bank or WFAL 2 of this Agreement or
any of the Collateral (or any part thereof).

<PAGE>   17

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

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

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

<PAGE>   18

pursuant to this Agreement to act as attorney-in-fact of the Bank and WFAL 2,
and each of them, for purposes of this Agreement. Each such successor Master
Collateral Agent shall provide the Bank, WFAL 2 and Financial Security with its
address, and its telephone and telecopier numbers, to be used for purposes of
Section 7.05 hereof, in a notice complying with the terms of said Section.

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

banking association, duly organized, validly existing and in good standing.

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

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

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

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

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

         Section 5.05. Noninterference, etc.. The Bank and WFAL 2 shall not take

                                   ARTICLE VI

                              REMEDIES UPON DEFAULT

         Section 6.01. Rights and Remedies Upon Default.

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

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

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

<PAGE>   22

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

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

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

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


                                   ARTICLE VII

                                     CUSTODY

         Section 7.01. Collateral Schedule; Collateral Files. On each date on
which the Bank and/or WFAL 2 pledge items of Collateral to the Master Collateral
Agent hereunder (each such date, a "Pledge Date"), the Bank and WFAL 2 shall
deliver to the Master Collateral Agent, the Trustee and Financial Security a
schedule of Collateral (each, a "Collateral Schedule") which, as to each item of
Collateral, sets forth, to the extent applicable, the obligor's name, the loan
or other identifying number, the interest rate, the original principal balance,
the outstanding principal balance, the origination or issue date, the scheduled
monthly principal and interest payment and the maturity date.

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

<PAGE>   23

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

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

<PAGE>   24

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

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

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

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

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

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

         Section 7.04. Master Collateral Agent's Interest in Collateral. By
execution of this Agreement, the Master Collateral Agent warrants and covenants
that it currently does not hold, and during the existence of this Agreement will
not hold, any adverse interest, by way of security 

<PAGE>   25

or otherwise, in any Collateral and hereby waives and releases any such interest
which it may have or acquire in the future. The Master Collateral Agent
expressly waives (i) any lien which might arise in connection with unpaid fees
or any lien which might arise in connection with any other claims against any
party hereto and (ii) any possessory lien, claim or right of set-off with
respect to any Collateral.


                                  ARTICLE VIII

                                  MISCELLANEOUS

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

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

         Section 8.03. Amendments. This Agreement may be amended, changed,
modified, altered or terminated only by written instrument or written
instruments signed by each of the parties hereto; provided that the consent of
the Master Collateral Agent shall not be withheld or delayed with respect to any
amendment that does not adversely affect the Master Collateral Agent and,
provided further that Schedule A hereto may be amended or replaced as set forth
in Section 2.03 (d) hereof. The Original Agreement, as amended and restated
hereby, shall remain in full force and effect.

         Section 8.04. Severability. In the event that any provision of this
Agreement or the application thereof to any party hereto or to any circumstance
or in any jurisdiction governing this Agreement shall, to any extent, be invalid
or unenforceable under any applicable statute, regulation or rule of law, then
such provision shall be deemed inoperative to the extent that it is invalid or
unenforceable and the remainder of this Agreement, and the application of any
such invalid or unenforceable provision to the parties, jurisdictions or
circumstances other than to whom or to which it is held invalid or
unenforceable, shall not be affected thereby nor shall the same affect the
validity or enforceability of any other provision of this Agreement. The parties

<PAGE>   26

hereto further agree that the holding by any court of competent jurisdiction
that any remedy pursued by the Master Collateral Agent or by the Controlling
Party hereunder is unavailable or unenforceable shall not affect in any way the
ability of the Master Collateral Agent or the Controlling Party to pursue any
other remedy available to it.

         Section 8.05. Notices. All notices, demands, certificates, requests and
communications hereunder ("notices") shall be in writing and shall be effective
(a) upon receipt when sent through the U.S. mails, registered or certified mail,
return receipt requested, postage prepaid, with such receipt to be effective the

                                 PROMISSORY NOTE


$50,000,000                                                       August 1, 1997


                  FOR VALUE RECEIVED, the undersigned, WFS FINANCIAL INC, a
California corporation (the "Maker"), promises to pay to the order of WESTERN
FINANCIAL BANK, F.S.B., a federal Bank (the "Bank"), the principal sum of FIFTY
MILLION DOLLARS ($50,000,000) (the "Principal") on or before July 31, 2007.

                  Interest on Principal. The Principal shall bear interest at a
fixed rate per annum of nine and forty-two hundredths percent (9 42/100%) (the
"Rate of Interest"). Such interest shall be payable quarterly in arrears, on the
last day of January, April, July and October of each year commencing on October
31, 1997; provided, however, that in the event any such payment date is not a
business day, then on the next business day thereafter (and such extension of
time shall be excluded in the computation of interest). All interest payable
pursuant to this Section 2 and Section 8 hereof (i) is hereinafter collectively
referred to as "Interest", and (ii) shall be calculated on the basis of 30 day
months on the basis of a year of 360 days.

                  Scheduled Payments of Principal. Subject to the acceleration
provisions of Section 5 hereof, the Principal shall be payable in two equal
annual installments of $25,000,000 commencing on July 31, 2001.

                  Payments. The Principal, Interest and "Costs" (as defined
herein) are collectively referred to herein as the "Obligations". All payments
of the Obligations shall be payable in lawful money of the United States of
America at:

                            16485 Laguna Canyon Road
                            Irvine, California 92618

or wherever otherwise designated in writing from time to time by the holder of
this Note. All payments made under this Note shall be credited first to Costs
(to the extent such Costs have not been paid in accordance with Section 5
hereof), then to Interest to the extent accrued and unpaid, and then to
Principal. All payments by the Maker under this Note (i) shall be made without
setoff or counterclaim, and (ii) shall be made under all circumstances,
irrespective of any restrictions then existing in any jurisdiction and without
requiring the fulfillment of any formality.

                  Costs. The Maker shall pay to the Bank all Costs incurred by
the Bank as and when so incurred. "Costs" shall mean all costs and expenses
incurred by or on behalf of the Bank (including, without limitation, all
reasonable attorneys' fees and expenses) in connection with the collection and
enforcement of this Note.

                  Acceleration.

                  5.1 As used herein, the term "Event of Default" shall mean the
         occurrence of any of the following events:

                                    A default in the payment when due and in the
                  manner prescribed herein of any installment of Principal or
                  Interest and such default shall not be cured within seven (7)
                  business days after the Bank has given written notice to the
                  Maker of such default.

                                    The failure, refusal or neglect of the Maker
                  to observe or perform for any reason any of the covenants,
                  conditions, agreements or provisions contained in this Note
                  (other than the payment of any Obligation of which the failure
                  to pay constitutes an Event of Default described in clause (i)
                  immediately above) and such failure, refusal or neglect shall
                  not be cured within forty-five (45) days after the Bank has
                  given written notice to the Maker of such failure, refusal or
                  neglect.

                                    Any representation or warranty made by the
                  Maker in this Note shall prove to have been false or
                  misleading in any material respect.

                                    The Maker shall be dissolved or shall
                  sustain the loss, cancellation or forfeiture of its legal
                  status or good standing by reason of any judicial,
                  extra-judicial or administrative proceedings or otherwise, or
                  shall (a) apply for or consent to the appointment of a
                  receiver, trustee or liquidator of the Maker or of all or a
                  substantial part of the Maker's assets; (b) be unable to, or
                  admit in writing its inability to, pay its debts as they
                  mature; (c) make a general assignment for the benefit of
                  creditors; (d) be adjudicated a bankrupt or insolvent; (e)
                  file a voluntary petition in bankruptcy or a petition or an
                  answer seeking reorganization or an arrangement for the
                  benefit of creditors or take advantage of any insolvency law
                  in its capacity as a debtor; (f) interpose an answer admitting
                  the material allegations of the petition filed against the
                  Maker in any bankruptcy, reorganization or insolvency
                  proceedings; (g) take any action which would have the effect
                  of dissolving the Maker; or (h) take any action for the
                  purpose of effecting any of the foregoing.

                                    Any (a) involuntary petition is filed
                  against the Maker seeking to subject it to any bankruptcy,
                  insolvency or similar laws and such petition shall remain
                  unstayed or not be withdrawn for a period of forty-five (45)
                  days; or (ii) order, judgment or decree shall be entered
                  against the Maker by any court of competent jurisdiction
                  approving a petition seeking its reorganization or appointment
                  of a receiver, trustee or liquidator of the Maker or of all or
                  a substantial part of its assets and such order, judgment or
                  decree shall continue and stay in effect for a period of
                  forty-five (45) days.

                  5.2 Upon the occurrence of an Event of Default, the Bank may
         declare all of the Obligations to be forthwith due and payable,
         whereupon all such Obligations shall become immediately due and payable
         without presentment, demand or notice of any kind to the Maker;
         provided, however, that such acceleration shall be automatic upon the
         occurrence of an Event of Default specified in clauses (iv) or (v) of
         Section 5.1 hereof, and no declaration or other act of the Bank shall
         be necessary to effect such acceleration.

                  Waiver of Notice. The Maker hereby waives diligence, demand,
protest, presentment for payment and notice of protest, dishonor and non-payment
of and formalities of any kind relative to this Note and agrees that the time of
payment hereunder may be extended by the Bank or this Note renewed by the Bank,
without notice and without releasing the Maker. The right to plead any and all
statutes of limitations as a defense to this Note is hereby waived to the
fullest extent permitted by law.

                  Overdue Obligations. All Obligations not paid on or before the
applicable due date shall bear interest until paid at the Rate of Interest.

<PAGE>   3

                  Maximum Rate. No provision of this Note shall be deemed to
establish or require the payment of interest at a rate in excess of the maximum
rate permitted by applicable law. In the event that the interest required to be
paid under this Note exceeds the maximum rate permitted by applicable law, the
interest required to be paid hereunder shall be automatically reduced to the
maximum rate permitted by applicable law. In the event any interest paid exceeds
the then applicable legal rate, the excess of such interest over the maximum
amount of interest permitted to be charged shall automatically be deemed to be
applied to reduce unpaid Costs, if any; then to reduce accrued and unpaid
interest, if any; and then to reduce Principal; the balance of any excess
interest remaining after application of the foregoing, if any, shall be refunded
to the Maker.

                  Governing Law. This Note (i) shall be subject to, construed
and governed by, the laws of the State of California without giving effect to
such state's conflict of law provisions, (ii) shall be binding upon the
successors and assigns of the Maker, and (iii) shall inure to the benefit of the
Bank and its successors and assigns. Notwithstanding the foregoing, the Maker
may not assign its obligations under this Note without the prior written consent
of the Bank.

                  Severability of Provisions. Any provision of this Note which
is invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without invalidating the remaining provisions hereof, and any
such invalidity, illegality or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provisions in any other jurisdiction.

                  Enforceability. By its execution hereof, the Maker represents
and warrants to the Bank that this Note is its valid and binding obligation,
enforceable according to its terms, and agrees to be liable for all Obligations
hereunder.

                  No Waiver. No waiver on the part of the Bank in exercising, or
partial exercise of, any right, power or privilege under this Note shall operate
as a waiver of any privilege or right hereunder of the Bank or preclude any
other further exercise of any right, power or privilege.

         14. Senior Indebtedness. Maker hereby covenants that until this Note is
paid in full, the Maker will not incur any indebtedness which is senior to the
obligations evidenced by this Note, other than (i) indebtedness under that
certain Promissory Note in the amount of $125,000,000 dated as of May 1, 1995,
between the Maker and the Bank; (ii) any indebtedness collateralized or secured
under that certain Revolving Line of Credit Agreement dated as of May 1, 1995,
between the Maker and the Bank; and (iii) other indebtedness for similar types
of warehouse credit.

         IN WITNESS WHEREOF, the Maker has caused this Note to be executed and
delivered by its duly authorized signatory as of the date and year first above
written.

and may use the cash for continuing operations. The Bank agrees to, and shall,
pay WFS interest on the principal amount as though the cash were invested.
Interest shall be paid at a rate equal to the monthly average of the Federal
Corporate 30-Day Commercial rate in effect at the time of investment and shall
accrue daily.

4. The Bank acknowledges and agrees that cash given by WFS to the Bank pursuant
to the terms of this Agreement for investment purposes is not a deposit to any
deposit account established by WFS at the Bank and will not be credited by the
Bank to any such account.

5. WFS, upon a determination that it desires to withdraw invested cash, shall
submit to the Bank a Certificate showing, as a minimum, the withdrawal date
("Withdrawal Date"), the amount to be withdrawn and the name of the payee. Upon

                                    AGREEMENT

     In consideration of the mutual promises set forth herein, and in reliance
upon the recitals set forth above, the parties agree as follows:

     1. Services Performed By One Company For the Benefit of Other Companies.
Certain services are performed by one Company ("Performing Company") for itself
and for other Companies ("Benefiting Company"). These costs are not always
directly traceable to each Benefiting Company; or such tracing cannot be
economically or practically accomplished; or the value of such goods and
services are not sufficiently substantial, as a portion of Performing Company's
total expenditure for such goods and services, as to be separately calculated.
Therefore, each Benefiting Company agrees that it shall reimburse Performing
Company for aggregate categories of such goods and services at the rates and
using the methods specified for each category in the attached Exhibit "A", as
amended from time to time, which is incorporated herein and made part of this
Agreement. The Companies have determined that the method and rate for each
category most accurately reflect the amount of services devoted by Performing
Company to each Benefiting Company. Methods and rates shall be calculated as of
the effective date of this agreement and recalculated each January 1st for the
upcoming year, or more frequently if a material change occurs.

     Performing Companies and the services currently provided by them are set
out below. An amendment to Exhibit "A" is sufficient to amend this list.

                (a) Services Provided by Westcorp. Cash management and treasury
services, hedging, tax preparation and filing, purchasing, mail services,
facilities management, lease administration, security, payroll, and personnel
and human resources support services.

                (b) Services Provided by the Bank. Regulatory compliance,
internal asset review, and safety and soundness of asset quality.

                (c) Services Provided by WFS. Network and personal computer
operations, account processing, and some legal services.

     Pursuant to Recital F, above, Westcorp shall reimburse other Companies for,
or shall be directly responsible for, all direct costs incurred by a Company on
behalf of WII for the benefit of Westcorp.

     Pursuant to Recital G, above, WFS shall reimburse other Companies for, or
shall be directly responsible for, all direct costs incurred by a Company on
behalf of WFAL, WFAL2, and WFSII for the benefit of WFS.

     2. Direct Costs. Direct costing shall be used when a specific service or
product directly benefits a Company and the costs of the service or product is
readily identifiable and measurable. For example, invoices from third party
suppliers of goods or services, will be treated as direct costs and paid
directly by Benefiting Company as incurred. Where appropriate, Companies shall
enter into separate agreements for such goods and services.

     Pursuant to Recital F, above, Westcorp shall reimburse other Companies for,
or shall be directly responsible for, all direct costs incurred by a Company on
behalf of WII for the benefit of Westcorp.

     Pursuant to Recital G, above, WFS shall reimburse other Companies for, or
shall be directly responsible for, all direct costs incurred by a Company on
behalf of WFAL, WFAL2, and WFSII for the benefit of WFS.

<PAGE>   3

     3. Space and Office Services. A Company, from time to time and at different
times, may permit another Company to occupy certain space at specific locations
owned or leased by Company. At particular locations, certain office services,
including without limitation, receptionist, telecommunications, and photocopying
services, may be included in the occupancy arrangement. Because locations and
services may be changed or canceled and additional locations and services may be
requested and provided, locations, services and the compensation for them are as
set forth in Exhibit "B", as amended from time to time, attached hereto and
incorporated herein. WFI uses approximately 120 square feet of space in each of
the Bank's retail branches for the sale of non-insured products. Pursuant to
regulations, the space is clearly identified and separate from the retail
operation. The occupancy and use of any particular space or service may be
terminated by either Company with ten (10) day notice to the other Company
without affecting the occupancy or use of any other space or service. There is
no requirement that a Company must occupy any particular space for any
particular period of time.

     Pursuant to Recital F, above, Westcorp shall reimburse other Companies for,
or shall be directly responsible for, all direct costs incurred by a Company on
behalf of WII for the benefit of Westcorp.

     Pursuant to Recital G, above, WFS shall reimburse other Companies for, or
shall be directly responsible for, all direct costs incurred by a Company on
behalf of WFAL, WFAL2, and WFSII for the benefit of WFS.

     4. Director/Officer Costs. An employee of Westcorp ("Executive") devotes
substantially all his time to other Companies and each Benefiting Company
recognizes it should reimburse Westcorp for time spent by Executive on
Benefiting Company's business. The allocation of Executive's compensation to
each Benefiting Company is included in Exhibit "A".

     Certain employees of the Companies serve as directors and officers of other
Companies in addition to their regular job functions or devote a substantial
amount of their time to other Companies' business. Their salaries and benefits
are paid by their employer ("Employer"). Therefore, this Agreement provides for
Benefiting Company to reimburse Employer on a monthly basis for that portion of
the time spent by employees on Benefiting Company's business. This service will
be provided by Employer to Benefiting Company on a flat fee basis for officers
and directors and is intended to cover those instances where specific employees
devote more than an incidental or indivisible segment of time to the affairs of
Company in the capacity of an officer or director. In those instances where
employees spend a substantial amount of time on a Company's business, the
service is provided on a direct cost basis. The flat fee shall be an hourly
rate, which is a blended rate calculated as the average compensation of all
employees except Executive, regardless of their Employer, who serve as officers
and directors of Companies. Because the directors and officers change from time
to time, as will the calculation of the fee, the specific persons and current
fee are shown on Exhibit "C", as amended from time to time, attached hereto and
incorporated herein by reference. Each person shall estimate the number of hours
per month which he/she devotes to a Company as an officer or director thereof
and shall notify the controller of his/her Company annually or upon any material
change in the estimate.

<PAGE>   4

     Pursuant to Recital F, above, Westcorp shall reimburse other Companies for,
or shall be directly responsible for, all Director/Officer costs incurred by a
Company on behalf of WII for the benefit of Westcorp.

     Pursuant to Recital G, above, WFS shall reimburse other Companies for, or
shall be directly responsible for, all Director/Officer costs incurred by a
Company on behalf of WFAL, WFAL2, and WFSII for the benefit of WFS.

     5. Reconveyance Fees. WRC is trustee on trust deeds loans made by the Bank
and provides reconveyance services to the Bank. WRC also provides reconveyance
services on real estate loans made by THC. The Bank, for itself and for THC,
shall pay a fee to WRC, which shall not exceed the maximum allowable statutory
fee, for each reconveyance processed by WRC. The current fee is set at $65.00
per reconveyance. This fee is payable whether or not the Bank or THC, as
beneficiary under the trust deeds being reconveyed, is paid by the subject
borrowers. In the event any such reconveyance fees are paid directly to WRC or
THC by third parties, such receipts shall be credited to the Bank for fees due
under this Paragraph.

     6. Time and Method of Payment. Reimbursement for allocated costs shall be
payable by each Company to others Companies on a monthly basis by the 20th day
of each month for expenses and costs incurred during the prior month. The
Accounting Department of each Company under the direction of the Controller
shall administer the reimbursement and reflect the reimbursement on the separate
books and records of each Company.

     7. Term.

                7.1 This Agreement shall commence as of the date stated above
and shall continue until terminated by the parties.

                7.2 This Agreement may be terminated immediately for breach of
any covenant, obligation, or duty herein contained or for violation of law,
ordinance, statute, rule or regulation (collectively referred to as "law")
governing the conduct of any party hereto.

                7.3 Termination shall not affect the obligations of the
Companies with respect to any event occurring before termination. Each Company
shall be bound by and responsible for any transaction or expense properly agreed
to or incurred by another Company in connection with services performed
hereunder but not settled, paid or reimbursed prior to the date of any such
termination. Upon termination of this Agreement, the fee referred to above will
be prorated, but the due date thereof shall not be changed.

     8. Representations and Warranties of Company. Each Company on its behalf
alone represents and warrants to and for the benefit of other Companies as
follows:

                8.1 Corporate Existence and Qualifications. Company is a
