                               PROSPECTUS SUMMARY
 
   
     This summary is qualified by more detailed information appearing in other
sections of this prospectus. The other information is important, so please read
this entire prospectus carefully. Our fiscal year ends on the Sunday nearest to
January 31 and is named for the calendar year just ended (for example, our
fiscal year ended February 1, 1998 is called "fiscal 1997"). Occasionally, this
results in a fiscal year which is 53 weeks long. Our company is a holding
company with no business operations of its own; all of its business is conducted
through its wholly-owned subsidiary, CSK Auto, Inc. Unless otherwise indicated,
"we," "us," "our" and similar terms, as well as references to the "Company,"
refer to CSK Auto Corporation and its subsidiaries.
    
 
                                  THE COMPANY
 
     CSK Auto Corporation is the largest retailer of automotive parts and
accessories in the Western United States and one of the largest such retailers
in the United States based, in each case, on our number of stores. As of
November 1, 1998, we operated 773 stores as one fully integrated company under
the following three brand names:
 
     - Checker Auto Parts, founded in 1968 and operating in the Southwestern and
       Rocky Mountain states;
 
     - Schuck's Auto Supply, founded in 1917 and operating in the Pacific
       Northwest; and
 
     - Kragen Auto Parts, founded in 1947 and operating primarily in California.
 
     Based on our store count, we believe we are the largest retailer of
automotive parts and accessories in 19 of our 24 markets.
 
     We offer a broad selection of national brand name and private label
automotive products, including new and remanufactured automotive replacement
parts, maintenance items and accessories. Most of our sales are to
do-it-yourself customers, although our commercial sales program focusing on
sales to auto repair professionals and fleet owners represents a significant and
increasing part of our business. Our stores typically offer between 13,000 and
17,000 stock keeping units ("SKUs"). Our operating strategy is to offer our
products at everyday low prices and at conveniently located and attractively
designed stores, supported by highly trained, efficient and courteous customer
service personnel.
 
OPERATING AND GROWTH STRATEGIES
 
     Over the past several years, we have implemented a variety of operating
initiatives which have enabled us to significantly increase our productivity and
the level and quality of service we provide to our customers. These operating
initiatives include:
 
     - EXPANDED PRODUCT SELECTION -- Our priority parts operation enables us to
       provide to customers on a timely basis products not usually stocked in
       each store's inventory. This has resulted in over 80% of our stores
       having 200,000 additional SKUs available to customers on a same-day
       delivery basis and all of our stores having an additional 1,000,000 SKUs
       available on a next day basis.
                                        3
<PAGE>   5
 
     - IMPROVED WAREHOUSE AND DISTRIBUTION SYSTEM -- We converted our warehouse
       and distribution system to a technologically advanced, fully integrated
       system. Our new system has allowed us to lower our warehouse and
       distribution expense as a percentage of net sales from 4.9% in fiscal
       1995 to 3.3% for the first half of fiscal 1998.
 
     - ENHANCED STORE LEVEL INFORMATION SYSTEMS -- We installed sophisticated
       store-level information systems which have improved store labor
       productivity and customer service.
 
     These operating initiatives have provided us with a highly efficient,
centralized infrastructure and the foundation for continued and profitable
growth. We are currently generating growth in sales and operating profits
primarily by implementing the following growth initiatives:
 
     - ACCELERATING STORE GROWTH -- We are accelerating our store growth
       strategy so we are able to profitably increase our name recognition and
       market penetration while benefiting from economies of scale in
       advertising, management and distribution costs. We plan to open, relocate
       or expand approximately 130 stores in fiscal 1998 and approximately 150
       stores in fiscal 1999. This compares to 64 stores in fiscal 1996 and 104
       stores in fiscal 1997 (in addition to 82 stores acquired from Trak Auto
       Corporation).
 
     - EXPANDING COMMERCIAL SALES PROGRAM -- Our rapidly growing and profitable
       commercial sales program targets the largest and fastest growing part of
       the automotive aftermarket. We believe that we have significant
       competitive advantages in servicing this segment because of our
       experienced sales associates, conveniently located stores, attractive
       pricing and ability to consistently deliver a broad product offering. Our
       commercial sales have increased 30% to $74.9 million in the first half of
       fiscal 1998 from $57.7 million in the comparable period in fiscal 1997.
 
   
     - INCREASING OPERATING PROFIT MARGIN -- As a result of continued
       improvement in our gross profit margin and continued realization of
       operating efficiencies, our operating profit margin increased to 6.2% in
       the first half of fiscal 1998 from 4.6% in the comparable period of
       fiscal 1997. Excluding $6.7 million of non-recurring charges, our
       operating profit margin for the first half of fiscal 1998 was 7.5%. Our
       gross profit margin is increasing primarily as a result of more favorable
       vendor terms, taking advantage of cash discounts from vendors and
       improvements in our product mix.
    
 
     The success of our operating and growth initiatives has resulted in a 58%
increase in our operating profit to $30.2 million for the first half of fiscal
1998, from $19.1 million in the comparable period in fiscal 1997. Excluding $6.7
million of non-recurring charges, operating profit for the first half of fiscal
1998 was $36.9 million, an increase of 93% over the comparable period of fiscal
1997. We believe that we can continue to realize strong and profitable growth by
aggressively pursuing our operating and growth initiatives.

     - In March 1998, we completed the initial public offering of our common
       stock and used the net proceeds of $159.1 million to repay outstanding

(1) Results of operations for the thirty-nine weeks ended November 1, 1998
    include: (1) an extraordinary loss of $6.8 million, which consisted
    primarily of the premiums paid in connection with the retirement of
    outstanding debt with the proceeds of our IPO and the write-off of a portion
    of deferred debt issuance costs; (2) $3.1 million of transition and
    integration expenses associated with the Trak West Acquisition; and (3) the
    write-off of a $3.6 million prepaid management fee. Excluding these
    non-recurring items, and the related income tax thereon, net income for the
    thirty-nine weeks ended November 1, 1998, was $23.4 million or $0.82 per
    diluted share (based on 28.6 million shares outstanding).

                  NOTES TO SUMMARY CONSOLIDATED FINANCIAL DATA
------------------------------
 
(1) The summary financial data for the first half of fiscal years 1997 and 1998
    are unaudited and include, in the opinion of our management, all
    adjustments, consisting only of normal recurring adjustments, necessary to
    fairly present the data for such periods. The interim results are not
    necessarily indicative of the results expected for a full fiscal year or for
    any future period.
 
(2) Our fiscal year consists of 52 or 53 weeks, ends on the Sunday nearest to
    January 31 and is named for the calendar year just ended (for example, our
    fiscal year ended February 1, 1998 is called "fiscal 1997"). All fiscal
    years presented had 52 weeks except for fiscal 1996, which had 53 weeks.
 
(3) Results of operations in fiscal 1995 include pre-opening expenses of $1.6
    million associated with the opening of our new distribution center in
    Phoenix, Arizona. Our fiscal 1995 operating and administrative expenses also
    include $5.3 million of software development costs associated with the new
    store-level information systems we installed during fiscal 1995. In
    addition, we believe that our operations and operating results were
    adversely impacted during fiscal 1995 as a result of the start-up costs
    associated with the implementation of many new initiatives.
 
(4) Results of operations in fiscal 1996 include certain non-recurring charges
    which were incurred when the 1996 Recapitalization was consummated,
    including the following: (1) amounts paid to members of management pursuant
    to existing equity participation agreements of $19.9 million ($20.2 million
    including a provision for estimated payroll taxes thereon), and (2) expenses
    incurred in connection with the 1996 Recapitalization of $12.5 million. Our
    fiscal 1996 results also include a charge of $12.9 million for store closing
    costs.
 
(5) In December 1997, we acquired 82 Trak West stores and have included these
    stores in our results of operations from the date of acquisition. Results of
    operations in fiscal 1997 include: (1) an extraordinary loss of $3.0 million
    to reflect the write-off of certain deferred financing costs associated with
    the early extinguishment of our previous senior credit facility; (2) $3.4
    million of transition and integration expenses associated with the Trak West
    Acquisition; and (3) $1.0 million of other 1996 Recapitalization expenses.
    The Trak West stores are not included in the number of new, relocated and
    expanded stores.
 
(6) Results of operations for the first half of fiscal 1998 include: (1) an
    extraordinary loss of $6.8 million, which consisted primarily of the
    premiums paid in connection with the retirement of outstanding debt with the
    proceeds of our IPO and the write-off of a portion of deferred debt issuance
    costs; (2) $3.1 million of transition and integration expenses associated
    with the Trak West Acquisition; and (3) the write-off of a $3.6 million
    prepaid management fee. Excluding these non-recurring items, and the related
    income tax thereon, net income for the first half of fiscal 1998 was $12.8
    million.
 
(7) EBITDA represents income before net interest expense, provision for income
    taxes, depreciation and amortization expense, other non-cash charges,
    extraordinary items and non-recurring charges. While EBITDA is not intended
    to represent cash flow from operations as defined by generally accepted
    accounting principles ("GAAP") (and should not be considered as an indicator
    of operating performance or an alternative to cash flow (as measured by
    GAAP)), it is included herein because we believe it is a meaningful measure
    which provides additional information with respect to our ability to meet
    our future debt service, capital expenditure and working capital
    requirements. EBITDA has been calculated as described above in accordance
    with the terms of the indenture under which our 11% Senior Subordinated
    Notes were issued and may differ in method of calculation from similarly
    titled measures used by other companies. Our 11% Senior Subordinated Notes
    are described in the "Description of Certain Indebtedness" section of this
    prospectus.

    EBITDAR represents EBITDA plus operating lease rental expense. Because the
    proportion of stores leased versus owned varies among industry competitors,
    we believe that EBITDAR permits a meaningful comparison of operating
    performance among industry competitors. We lease substantially all of our
    stores.
 
(8) Represents sales to commercial accounts, including sales from stores without
    commercial sales centers.
 
(9) Comparable store net sales data is calculated based on the change in net
    sales commencing after the time a new store has been open twelve months.
    Therefore, sales for the first twelve months a new store is open are not
    included in the comparable store calculation. As a result, the sales of the
    82 acquired Trak West stores are not yet reflected in our computation of
    comparable store net sales. Relocations are included in comparable store net
    sales from the date of opening.

these statements by forward-looking words such as "may," "will," "expect,"
"anticipate," "believe," "estimate" and "continue" or similar words. You should
read statements that contain these words carefully because they: (1) discuss our
future expectations; (2) contain projections of our future results of operations
or of our financial condition; or (3) state other "forward-looking" information.
We believe that it is important to communicate our future expectations to our
investors. However, there may be events in the future that we are not able to
accurately predict or over which we have no control. These events may include
future operating results, our efforts to address Year 2000 issues and potential
competition, among other things. The risk factors listed in this section, as
well as any cautionary language in this prospectus, provide examples of risks,
uncertainties and events that may cause our actual results to differ materially
from the expectations we describe in our forward-looking statements. Before you
invest in our common stock, you should be aware that the occurrence of the
events described in these risk factors and elsewhere in this prospectus could
have a material adverse effect on our business, operating results and financial
condition.
 
RISKS RELATED TO GROWTH STRATEGY
 
     Our plan to increase the number of stores we operate is subject to several
business risks, including:
 
     - We may not be able to identify or acquire new store sites that offer
       attractive returns on our investment.
 
     - We may encounter difficulties or delays in negotiating with landlords or
       sellers, or in constructing new, relocated or expanded stores.
 
     - The opening of new, relocated or expanded stores may hurt sales or
       profitability at our existing stores in a particular region or market
       area.
 
     - We may encounter operating difficulties in the process of integrating
       newly-acquired stores into our corporate systems, which could hurt our
       profitability.
 
     - It may be difficult to hire, train and retain the personnel to run new,
       relocated or expanded stores efficiently.

SUBSTANTIAL LEVERAGE AND DEBT SERVICE OBLIGATIONS
 
     Our balance sheet is highly leveraged with approximately $292.1 million in
funded debt and $85.7 million of stockholders' equity at August 2, 1998. This
relatively high leverage could negatively affect our operations in a number of
ways, including:
 
     - We may be unable to obtain additional financing when needed for our
       operations or when desired for acquisitions or expansions.
 
     - A large part of our cash flow from operations must be dedicated to
       interest payments on our debt, thereby reducing funds available for other
       corporate purposes.
 
     - Since our bank debt (approximately $187.6 million at August 2, 1998) is
       at variable or floating interest rates, if market rates rise, our debt
       service obligations will become more expensive.
 
     - The level of our debt could limit our flexibility in responding to
       downturns in the economy or in our business.
 
HISTORY OF PREVIOUS LOSSES DURING FOUR OF THE LAST FIVE FISCAL YEARS
 
     We incurred net losses during four of our last five fiscal years. While
income before taxes and extraordinary loss, excluding non-recurring expenses,
would have been $8.2 million for fiscal 1997 and would have been $20.3 million
for the first half of fiscal 1998, we can offer no assurance that we will be
profitable or achieve continued growth in operating profit in the future.
 
RESTRICTIVE LOAN COVENANTS
 
     Our Senior Credit Facility contains covenants which require us to satisfy
ongoing financial tests and which limit our ability to borrow additional money,
pay dividends, divest assets and make additional corporate investments. If we
issue additional equity securities, a certain portion must be used to reduce
borrowings under the Senior Credit Facility. If we are unable to meet any of our
debt service obligations or to comply with these covenants, our lenders can
accelerate our debt. If that were to occur and we are unable to obtain
alternative financing, we may face bankruptcy. We discuss the material terms of
this debt in the "Description of Certain Indebtedness" section of this
prospectus.
 
COMPETITION
 
     The retail sale of automotive parts and accessories is highly competitive.
We compete primarily with the following:
 
     - national and regional retail automotive parts chains;
 
     - wholesalers or jobber stores (some of which are associated with national
       parts distributors or associations);
 
     - automobile dealers that supply manufacturer parts; and
 
     - mass merchandisers that carry automotive replacement parts and
       accessories.
 
                                       11
<PAGE>   13
 
     Some of our competitors have more financial resources, are more
geographically diverse and have better name recognition than we have.
 
DEPENDENCE ON EXECUTIVE OFFICERS AND EMPLOYEES
 
     Our success depends to a significant degree on the efforts of our
management. The loss of one or more of our executive officers could adversely
affect us. We do not maintain "key person" life insurance on our executive
officers. In addition, there have been historically low levels of unemployment
in the regions in which our stores are located. This could lead to pressure on
wage rates and make it more difficult for us to attract and retain qualified
employees. Our continued success will be dependent upon our ability to retain
existing, and attract additional, qualified executives and employees.
 
SENSITIVITY TO REGIONAL ECONOMIC AND WEATHER CONDITIONS
 
     All of our stores are located in the Western United States, and therefore,
our business is sensitive to the economic and weather conditions of that region.
Unusually severe or inclement weather tends to reduce sales, particularly to our
do-it-yourself customers. However, extremely hot or cold temperatures tend to
enhance sales by causing auto parts to fail and by increasing demand for
seasonal products.
 
RISKS OF ACQUISITION GROWTH STRATEGY
 
     In the past, we have expanded our business through acquisitions and intend
to continue to pursue an opportunistic acquisition strategy. There are various
risks associated with this strategy, including those associated with the
integration of the new businesses into our management structure and operational
systems and the modification of our systems to handle the increased volume and
number of store locations.
 
CONTROL BY PRINCIPAL STOCKHOLDERS
 
   
     Upon consummation of this offering, members of the Investcorp Group, the
Carmel Group, and our senior management will own, in the aggregate,
approximately 43.7% of the outstanding shares of our common stock (39.9% if the
underwriters' overallotment option is exercised in full). These stockholders
will be able to exercise significant control over the Company through their
ability to determine the outcome of votes of stockholders regarding, among other
things, nomination and election of directors and approval of significant
transactions. The members of the Investcorp Group and the Carmel Group are party
to a stockholders' agreement which requires the groups to vote together on
certain matters, including the election of directors. We describe the Investcorp
Group and the Carmel Group in the "Principal and Selling Stockholders" section
of this prospectus and the stockholders' agreement in the "Certain Relationships
and Related Transactions" section of this prospectus.
    
 
EFFECT OF CHANGE OF CONTROL AND STATUTORY PROVISIONS
 
   
     Our Senior Credit Facility and the indenture governing our 11% Senior
Subordinated Notes contain provisions that, under certain circumstances, will
cause this debt to become due upon the
    
 
                                       12
<PAGE>   14
 
occurrence of a change of control, including the election to the board of
directors of a majority of directors that were not nominated by the Investcorp
Group. This offering will not cause a change of control. These provisions could
have the effect of making it more difficult for a third party to acquire control
of us.
 
     We are subject to the anti-takeover provisions of Section 203 of the
Delaware General Corporation Law. In general, the statute prohibits a publicly
held Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner.
 
POSSIBLE VOLATILITY OF OUR STOCK PRICE
 
     The stock market and the price of our common stock may be subject to
volatile fluctuations based on general economic and market conditions. The
market price for our common stock may also be affected by our ability to meet
analysts' expectations. Failure to meet such expectations, even slightly, could
have an adverse effect on the market price of our common stock. In addition,
stock market volatility has had a significant effect on the market prices of
securities issued by many companies for reasons unrelated to the operating
performance of these companies. In the past, following periods of volatility in
the market price of a company's securities, securities class action litigation
has often been instituted against such a company. If similar litigation were
instituted against us, it could result in substantial costs and a diversion of
our management's attention and resources, which could have an adverse effect on
our business.
 
SHARES ELIGIBLE FOR FUTURE SALE; POSSIBLE ADVERSE EFFECT ON FUTURE MARKET PRICE
 
     The market price of our common stock may fall as a result of sales of a
large number of shares in the market after this offering, or the perception that
such sales could occur.
 
   
     At November 1, 1998, there were 27,742,022 shares of common stock
outstanding. Of those shares, all of the shares sold in this offering, the
8,625,000 shares sold in our IPO and 3,634 shares issued pursuant to the
exercise of options under our stock option plans will be freely transferable
without restriction under the Securities Act of 1933, as amended (the
"Securities Act"), except for shares acquired by one of our "affiliates" as that
term is defined under the Securities Act. The remaining 12,113,388 outstanding
shares of our common stock are deemed to be "restricted securities," as that
term is defined in Rule 144 under the Securities Act and are eligible for sale
in the public market in compliance with Rule 144. The holders of 11,932,788
shares of common stock will have contractual registration rights with respect to
those shares.
    
 
     Subject to certain exceptions, we and certain of our stockholders owning an
aggregate of 11,932,788 shares, have agreed that they will not offer, issue,
pledge, sell, transfer or otherwise dispose of any shares of our common stock or
securities convertible into or exercisable or exchangeable for shares of our
common stock for a period of 90 days after the date of this prospectus without
the prior written consent of Donaldson, Lufkin & Jenrette Securities
Corporation. We can offer no assurance that an increase in the number of shares
of common stock that are freely tradeable will not adversely affect the market
price of our common stock after this offering.

YEAR 2000 CONVERSION
 
     Historically, certain computerized systems have used two digits rather than
four to define the applicable year. Computer equipment and software and devices
with imbedded technology that are time-sensitive may recognize a date using "00"
as the year 1900 rather than the year 2000, resulting in system failure or
miscalculations. This problem is generally referred to as the "Year 2000 issue."
 
     Although we anticipate minimal business disruption will occur in our
systems as a result of the Year 2000 issue, possible consequences include a loss
of communications links with certain store locations, and the inability to
process transactions, send purchase orders, or engage in similar normal business
activities. We presently believe that with modifications to existing software
and conversions to new software, the risk of our Year 2000 conversion can be
mitigated. However, if we do not make the necessary modifications and
conversions, or do not complete them in a timely manner, it could have a
material adverse effect on our operations. We discuss our Year 2000 conversion
in the "Management's Discussion and Analysis of Financial Condition and Results
of Operations" section of this prospectus.

     We currently do not intend to pay any dividends on our common stock.
 
     We are a holding company with no business operations of our own. We
therefore depend upon payments, dividends and distributions from CSK Auto, Inc.,
our wholly-owned subsidiary, for funds to pay dividends to our stockholders. CSK
Auto, Inc. currently intends to retain its earnings to fund its working capital,
debt repayment, and capital expenditures needs and for other general corporate
purposes. CSK Auto, Inc. has no current intention of paying dividends or making
other distributions to us in excess of amounts necessary to pay our operating
expenses and taxes. The Senior Credit Facility and the indenture governing the
11% Senior Subordinated Notes contain restrictions on CSK Auto, Inc.'s ability
to pay dividends or make payments or other distributions to us.

                                USE OF PROCEEDS
 
     We will not receive any proceeds from the sale of common stock in this
offering. We will pay certain legal, accounting and other expenses incidental to
the sale of shares by the selling stockholders. These costs are estimated to be
$600,000.

                                    DILUTION
 
   
     Our net tangible book value as of August 2, 1998 was approximately $75.5
million or $2.72 per share. Our net tangible book value per share is determined
by subtracting the total amount of our liabilities from the total amount of our
tangible assets and dividing the remainder by the number of shares of our common
stock outstanding. Our net tangible book value per share will not be affected by
this offering. The price per share to the public of the shares of common stock
offered hereby exceeds the net tangible book value per share prior to this
offering. Therefore, purchasers of shares of common stock in this offering will
realize immediate and substantial dilution in the net tangible book value of
their shares. The following table, based upon our net tangible book value as of
August 2, 1998, illustrates the dilution to purchasers of shares of our common
stock in this offering, based on an assumed public offering price of $28.19 per
share (the last sale price on November 19, 1998).

                 NOTES TO SELECTED CONSOLIDATED FINANCIAL DATA
 
------------------------------
 (1) Our fiscal year consists of 52 or 53 weeks, ends on the Sunday nearest to
     January 31 and is named for the calendar year just ended. All fiscal years
     presented had 52 weeks except for fiscal 1996, which had 53 weeks.
 
   
 (2) Our company was formed in July 1993 as a holding company for an entity
     which owned (1) CSK Auto, Inc., (2) another retailer of automotive parts
     and accessories, and (3) other immaterial operations. The information
     provided for fiscal 1993 prior to our formation reflects the operations of
     this entity on a predecessor basis, all of which operations other than CSK
     Auto, Inc. were sold, liquidated or disposed of prior to December 31, 1993.
    
 
 (3) Net income in fiscal 1994 includes an extraordinary gain of $97.2 million
     resulting from cancellation of a portion of our long-term debt.
 
 (4) Results of operations in fiscal 1995 include pre-opening expenses of $1.6
     million associated with the opening of our new distribution center in
     Phoenix, Arizona. Our fiscal 1995 operating and administrative expenses
     also include $5.3 million of software development costs associated with the
     new store-level information systems we installed during fiscal 1995. In
     addition, we believe that our operations and operating results were
     adversely impacted during fiscal 1995 as a result of the start-up costs
     associated with the implementation of many new initiatives.
 
   
 (5) Results of operations in fiscal 1996 include certain non-recurring charges
     which were incurred when the 1996 Recapitalization was consummated,
     including the following: (1) amounts paid to members of management pursuant
     to existing equity participation agreements of $19.9 million ($20.2 million
     including a provision for estimated payroll taxes thereon); and (2)
     expenses incurred in connection with the 1996 Recapitalization of $12.5
     million. Our fiscal 1996 results also include a charge of $12.9 million for
     store closing costs.
    
 
 (6) In December 1997, we acquired 82 Trak West stores which have been included
     in results of operations from the date of acquisition. Results of
     operations in fiscal 1997 include: (1) an extraordinary loss of $3.0
     million to reflect the write-off of certain deferred financing costs
     associated with the early extinguishment of the our previous senior credit
     facility; (2) $3.4 million of transition and integration expenses
     associated with the Trak West Acquisition; and (3) $1.0 million of other
     1996 Recapitalization expenses.
 
 (7) Results of operations for the first half of fiscal 1998 include: (1) an
     extraordinary loss of $6.8 million, which consisted primarily of the
     premiums paid in connection with the retirement of outstanding debt with
     the proceeds of our IPO and the write-off of a portion of deferred debt
     issuance costs; (2) $3.1 million of transition and integration expenses
     associated with the Trak West Acquisition; and (3) the write-off of a $3.6
     million prepaid management fee. Excluding these non-recurring items, and
     the related income tax thereon, net income for the first half of fiscal
     1998 was $12.8 million, or $0.45 per diluted share.

 (8) EBITDA represents income before net interest expense, provision for income
     taxes, depreciation and amortization expense, other non-cash charges,
     extraordinary items and non-recurring charges. While EBITDA is not intended
     to represent cash flow from operations as defined by GAAP (and should not
     be considered as an indicator of operating performance or an alternative to
     cash flow (as measured by GAAP)), it is included herein because we believe
     it is a meaningful measure which provides additional information with
     respect to our ability to meet our future debt service, capital expenditure
     and working capital requirements. EBITDA has been calculated as described
     above in accordance with the terms of the indenture under which our 11%
     Senior Subordinated Notes were issued and may differ in method of
     calculation from similarly titled measures used by other companies.
 
     The computation of EBITDA for each of the respective periods shown is as
     follows:

     EBITDAR represents EBITDA plus operating lease rental expense. Because the
     proportion of stores leased versus owned varies among industry competitors,
     we believe that EBITDAR permits a meaningful comparison of operating
     performance among industry competitors. We lease substantially all of our
     stores.
 
 (9) Represents sales to commercial accounts, including sales from stores
     without commercial sales centers.
 
(10) Comparable store net sales data is calculated based on the change in net
     sales commencing after the time a new store has been open twelve months.
     Therefore, sales for the first twelve months a new store is open are not
     included in the comparable store calculation. As a result, the sales of the
     82 acquired Trak West stores are not yet reflected in our computation of
     comparable store net sales. Relocations are included in comparable store
     net sales from the date of opening.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     Our fiscal year ends on the Sunday nearest to January 31 and is named for
the calendar year just ended. Occasionally this results in a fiscal year which
is 53 weeks long. When we refer to a particular fiscal year we mean the
following:
 
     - Fiscal 1998 means the 52 weeks ending January 31, 1999
 
     - Fiscal 1997 means the 52 weeks ended February 1, 1998
 
     - Fiscal 1996 means the 53 weeks ended February 2, 1997
 
     - Fiscal 1995 means the 52 weeks ended January 28, 1996
 
GENERAL
 
     CSK Auto Corporation is the largest retailer of automotive parts and
accessories in the Western United States and one of the largest retailers of
these products in the United States based, in each case, on our number of
stores. As of August 2, 1998, we operated 747 stores as one fully integrated
company under three brand names:
 
     - Checker Auto Parts, founded in 1968 and operating in the Southwestern and
       Rocky Mountain states;
 
     - Schuck's Auto Supply, founded in 1917 and operating in the Pacific
       Northwest; and
 
     - Kragen Auto Parts, founded in 1947 and operating primarily in California.
 
     Based on store count, we believe we are the largest retailer of automotive
parts and accessories in 19 of our 24 markets.
 
     Over the past several years, we have implemented a variety of initiatives
which have enabled us to significantly increase our productivity and the level
and quality of service we provide to customers. These initiatives include:
 
   
     - Expanding our product selection and priority parts operation;
    
 
   
     - Converting our warehouse and distribution system to a technologically
       advanced, fully-integrated system;
    
 
   
     - Installing sophisticated store-level information systems;
    
 
   
     - Accelerating our store growth strategy; and
    
 
   
     - Expanding our commercial sales program.
    
 
Largely as a result of the success of these programs, our profitability has
improved. We believe that these initiatives have provided the foundation for
continued and profitable growth.

     The discussion which follows includes several references to charges and
effects relating to the following significant transactions which occurred during
the period covered:
 
     - In October 1996, INVESTCORP S.A. and certain other investors (whom we
       refer to as the "Investcorp Group") purchased a 51% equity interest in
       our company in a series of related transactions resulting in a new
       capitalization structure for our company. We refer to these transactions
       as the "1996 Recapitalization."
 
     - In December 1997, we acquired 82 stores located in the Los Angeles market
       from Trak Auto Corporation for approximately $34.5 million. We refer to
       this transaction as the "Trak West Acquisition."
 
     - In March 1998, we completed the initial public offering of our common
       stock and used the net proceeds of $159.1 million to repay outstanding
       debt. We refer to this transaction as our "IPO."
 
     In connection with this offering, we expect to incur an aggregate of
approximately $600,000 in legal, accounting, printing and other costs. These
costs will be expensed in the fourth quarter of fiscal 1998.
 
   
RECENT FINANCIAL RESULTS
    
 
   
     On November 18, 1998, we publicly announced our financial results for the
third quarter of fiscal 1998. The complete financial statements for the
thirty-nine weeks ended November 1, 1998 are not presently available. Highlights
from our third quarter results include the following:
    
 
   
     - Our net sales increased 21.3% from our third quarter of fiscal 1997
       results to $263.1 million. Comparable store sales increased 3% during the
       third quarter. During the first three quarters of fiscal 1998, comparable
       store sales increased 1%. Our net sales growth was primarily due to the
       increase in the number of stores operated.
    
 
   
     - Our operating profit margin increased to 8.9% in the third quarter of
       fiscal 1998 from 7.9% in the third quarter of fiscal 1997. Our operating
       profit margin increased due primarily to our ability to obtain generally
       better pricing and more favorable terms and support from our vendors
       because of our improving operating results and financial condition.
    
 
   
     - Our net income increased to $10.5 million or $0.37 per diluted share
       compared to $4.3 million or $0.25 per diluted share for our third quarter
       of fiscal 1997. Net income increased due to the factors discussed above,
       together with lower interest expense resulting from our having less debt
       outstanding following the repayment of debt with the proceeds of the IPO.
    
 
   
     - We opened 27 new stores, relocated 5 stores and expanded 2 stores during
       the third quarter of fiscal 1998.

(1) Results of operations for the thirty-nine weeks ended November 1, 1998
    include: (1) an extraordinary loss of $6.8 million, which consisted
    primarily of the premiums paid in connection with the retirement of
    outstanding debt with the proceeds of our IPO and the write-off of a portion
    of deferred debt issuance costs; (2) $3.1 million of transition and
    integration expenses associated with the Trak West Acquisition; and (3) the
    write-off of a $3.6 million prepaid management fee. Excluding these
    non-recurring items, and the related income tax thereon, net income for the
    thirty-nine weeks ended November 1, 1998, was $23.4 million or $0.82 per
    diluted share (based on 28.6 million shares outstanding).

     Gross profit consists primarily of net sales less the cost of sales and
warehouse and distribution expenses. Gross profit as a percentage of net sales
may be affected by variations in our product mix, price changes in response to
competitive factors and fluctuations in merchandise costs and vendor programs.
 
     Operating and administrative expenses are comprised of store payroll, store
occupancy, advertising expenses, other store expenses and general and
administrative expenses, including salaries and related benefits of corporate
employees, administrative office occupancy expenses, data processing,
professional expenses and other related expenses.
 
FIRST HALF OF FISCAL 1998 COMPARED TO FIRST HALF OF FISCAL 1997
 
     Net sales for the first half of fiscal 1998 increased $73.6 million, or
17.5% over net sales for the first half of fiscal 1997, primarily reflecting an
increase in the number of stores operated. As a result of the acquisition of the
82 Trak West stores in December 1997 and new store openings, we operated 747
stores at the end of the first half of fiscal 1998 compared to 591 stores at the
end of the first half of fiscal 1997. Comparable store sales for the first half
of fiscal 1998 were flat compared to the prior-year period, due primarily to
unseasonably cooler temperatures and rain in many of our key markets through the
first quarter and early in the second quarter. During
 
                                       24
<PAGE>   26
 
the first half of fiscal 1998, we opened 33 new stores, expanded 2 stores,
relocated 19 stores and closed 4 stores in addition to those closed due to
relocations.
 
     Gross profit for the first half of fiscal 1998 was $225.4 million, or 45.7%
of net sales, compared to $177.3 million, or 42.3% of net sales, for the
comparable period of fiscal 1997. The increase in gross profit percentage
primarily resulted from our ability to obtain generally better pricing and more
favorable terms and support from our vendors due to improved financial
performance and stronger capitalization.
 
     Operating and administrative expenses increased by $30.3 million to $188.4
million, or 38.2% of net sales, for the first half of fiscal 1998 from $158.2
million, or 37.7% of net sales, for the comparable period of fiscal 1997. The
increase is primarily the result of the operating costs of new stores that are
in the early stages of maturation and the operating costs of the Trak West
stores, which exceed our company-wide average as a percent of sales. In
addition, we incurred a $3.1 million non-recurring expense during the first
quarter of fiscal 1998 to complete the integration of the Trak West stores into
our operations and a $3.6 million non-cash charge to write off the remaining
unamortized balance of a pre-paid management consulting and advisory services
agreement that terminated by its terms upon the consummation of our IPO.
 
     Operating profit increased to $30.2 million, or 6.2% of net sales, for the
first half of fiscal 1998 compared to $19.1 million, or 4.6% of net sales, for
the comparable period of fiscal 1997, due to the factors cited above.
 
     Interest expense for the first half of fiscal 1998 totaled $16.6 million
compared to $19.7 million for the comparable period of fiscal 1997. The expense
decreased primarily as the result of the early retirement of approximately
$147.6 million of outstanding debt with the proceeds of our IPO. The retirement
of this debt also caused an extraordinary loss of $6.8 million, net of tax,
which consisted primarily of prepayment premiums paid in connection with the
redemption of debt and the write-off of a portion of deferred debt issuance
costs.
 
     Income tax expense for the first half of fiscal 1998 was $5.0 million which
resulted in an effective rate of approximately 37%, as compared to an effective
rate of approximately 36% for the first half of fiscal 1997.
 
   
     Net income for the first half of fiscal 1998, excluding $3.1 million of
transition and integration expenses and the $3.6 million write-off of
unamortized management fees and the extraordinary loss was $12.8 million, or
$0.45 per diluted common share (based on 28.6 million shares outstanding),
compared to a net loss of $0.4 million, or $0.02 per diluted common share (based
on 17.1 million shares outstanding), for the comparable period of fiscal 1997.
Including the non-recurring charges and extraordinary loss, we reported net
income of $1.8 million, or $0.07 per diluted common share, for the first half of
fiscal 1998.
    
 
     As a result of the factors cited above, EBITDA increased by $19.1 million
to $48.3 million in the first half of fiscal 1998, compared to $29.2 million for
the comparable period of fiscal 1997.
 
FISCAL 1997 COMPARED TO 1996
 
     Net sales for fiscal 1997 increased $52.7 million, or 7%, over net sales
for fiscal 1996. Comparable store sales increased $29.9 million, or 4%, and new
stores contributed $22.2 million
 
                                       25
<PAGE>   27
 
to the increase in net sales for the fiscal year. Included in the $22.2 million
of new store sales is $10.6 million in net sales contributed by the former Trak
West stores acquired on December 8, 1997. During fiscal 1997, we opened 65 new
stores, relocated 36 stores, expanded 3 stores, sold 4 stores, closed 5 stores
in addition to those closed due to relocations and acquired the 82 Trak West
stores. At February 1, 1998, we had 718 stores in operation.
 
     Gross profit for fiscal 1997 was $377.6 million, or 44.6% of net sales,
compared to $329.7 million, or 41.6% of net sales, for fiscal 1996. The increase
in gross profit percentage resulted from our ability to obtain generally better
pricing and more favorable terms from our vendors as a result of our improving
operating results and financial condition. In addition, we realized an increase
in sales of automotive replacement parts which produce a higher gross profit
percentage than other product categories. Gross profit percentage was also
favorably affected by efficiencies achieved by our warehousing and distribution
systems.
 
     Operating and administrative expenses increased by $14.9 million to $327.8
million, or 38.8% of net sales, for fiscal 1997 from $312.9 million, or 39.5% of
net sales, for fiscal 1996. The increase in this expense is primarily the result
of the incremental operating costs of new stores that are in the early stages of
maturation. In addition, we incurred increased advertising costs of
approximately $1.9 million in fiscal 1997 as a result of a shift in the mix of
our advertising media from primarily print to a greater usage of radio and
television. Also, we incurred approximately $0.9 million of stock-based
compensation expense in fiscal 1997 as the result of the sale of stock to
certain members of management at a discount to its fair market value.
 
   
     Operating profit increased to $45.5 million, or 5.3% of net sales, for
fiscal 1997, compared to an operating loss of $3.4 million, or 0.4% of net
sales, for fiscal 1996. Significant items that affect the comparability of these
operating results include: (1) $1.6 million of store closing costs in fiscal
1997 compared to $14.9 million of store closing costs in fiscal 1996; (2) $3.4
million of transition and integration expense in fiscal 1997 associated with the
Trak West Acquisition compared with no such expense occurring in fiscal 1996;
and (3) $20.2 million of charges in fiscal 1996 in connection with certain
equity participation agreements which became payable as a result of the 1996
Recapitalization compared with no such charges occurring in fiscal 1997. The
1996 store closing costs include a charge of $12.9 million to reflect the store
closing costs of 91 specific store sites that were included in an update of our
strategic plan for store relocation and expansion as discussed below in the
comparison of fiscal 1996 to fiscal 1995.
    
 
     Interest expense for fiscal 1997 totaled $40.7 million compared to $20.7
million for fiscal 1996. The increase is the result of the issuance of new
subordinated debt and higher average bank borrowings.
 
     Income tax expense totaled $1.6 million in fiscal 1997, an effective tax
rate of 41%, compared to an income tax benefit of $11.9 million for fiscal 1996.
 
     We incurred an extraordinary loss of $3.0 million, net of income taxes, in
fiscal 1997 as a result of the write-off of the deferred financing costs
associated with the amendment and restatement of our Senior Credit Facility.
 
     As a result of the factors cited above, net loss decreased to $0.8 million
for fiscal 1997, compared to a net loss of $24.7 million for fiscal 1996.
 
                                       26
<PAGE>   28
 
     As a result of the factors cited, EBITDA increased by $19.7 million to
$70.2 million for fiscal 1997 compared to $50.5 million for fiscal 1996.
 
FISCAL 1996 COMPARED TO FISCAL 1995
 
     Net sales for fiscal 1996 increased by $74.7 million, or 10.4%, over net
sales for fiscal 1995. This increase was due to (1) an increase in comparable
store sales of 6%, or $42.5 million and (2) an increase in net sales from new
stores of $32.2 million. During fiscal 1996, we opened 19 new stores, relocated
37 stores, expanded 8 stores and closed five stores in addition to those closed
due to relocations.
 
     Gross profit for fiscal 1996 was $329.7 million, or 41.6% of net sales,
compared with $284.5 million, or 39.6% of net sales, during fiscal 1995. We
increased our gross profit percentage by (1) increasing the sales of automotive
replacement parts which produce a higher gross profit percentage than other
product categories, and (2) achieving efficiencies from our new warehouse and
distribution systems, which became fully operational in the fourth quarter of
fiscal 1995. We also believe that in fiscal 1996 we obtained better pricing from
vendors as a result of improvement in our financial performance and access to
credit accomplished during the year. These favorable factors were slightly
offset in fiscal 1996 by the lower gross margins on increased commercial sales
as compared to retail sales.
 
     Operating and administrative expenses for fiscal 1996 increased by $28.2
million over such expenses for fiscal 1995 but, as a percentage of net sales,
decreased to 39.5% from 39.6%. This decrease reflected our ability to leverage
our overhead and fixed expenses with higher sales volume despite an increase of
approximately $3.0 million in depreciation and amortization expense associated
with equipment installed as part of our investment in store-based information
systems.
 
     In January 1997, we updated our strategic plan relating to the relocation
of certain stores. The 1996 Recapitalization provided us with greater access to
capital resources and the availability of a sale-leaseback facility, and thereby
enhanced our ability to implement such relocations. While we believe that there
will be long-term operating benefits from our store relocation strategy,
implementing the strategy will involve costs for early lease terminations or
negative sub-lease rentals for vacated stores and, accordingly, we recorded a
charge to earnings of $12.9 million in January 1997, which increased the
provision for store closing costs to $14.9 million for fiscal 1996 from $3.3
million for fiscal 1995.
 
     The $12.9 million charge reflected store closing costs associated with 91
specific store sites included in the strategic plan. The store sites were
selected for relocation on the basis of their operating performance relative to
their size. We included stores in the plan for relocation because we identified
a larger, or otherwise more favorable, site within its market area. Stores were
scheduled to be closed at specific dates under the plan consistent with the
anticipated commencement of operations of the new store. We have historically
experienced sales growth shortly after opening the relocated stores.
 
     The $12.9 million charge consisted principally of future lease costs under
non-cancellable leases for the 91 specifically identified store locations (from
the planned vacancy date), related
 
                                       27
<PAGE>   29
 
estimates for vacancy periods, writeoffs of certain fixed assets and leasehold
improvements, and estimated credit losses with respect to sub-lease
arrangements. Substantially all of these relocations have been completed. Future
rents will be incurred through the expiration of the non-cancellable leases,
which range from August 1998 to May 2008.
 
     To recognize our obligations under pre-existing equity participation
agreements with members of management which became payable as a result of the
1996 Recapitalization, we recorded a charge of approximately $20.2 million in
the fourth quarter of fiscal 1996. See note 2 to our consolidated financial
statements. In addition, we incurred non-recurring expenses totaling $12.5
million which consisted primarily of consulting, legal and accounting fees
relating to the 1996 Recapitalization.
 
     Interest expense for fiscal 1996 was $20.7 million compared to $14.4
million for fiscal 1995. Higher average effective interest rates and the
issuance of approximately $181.9 million of new debt in connection with the 1996
Recapitalization caused the increase in interest expense.
 
   
     As a result of the factors cited above, we recorded a net loss of $24.7
million for fiscal 1996 as compared to a net loss of $9.1 million for fiscal
1995.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     Our primary cash requirements include working capital (primarily
inventory), debt service obligations and capital expenditures. We intend to
finance our cash requirements with cash flow from operations, funds from our
leasing facility and borrowings under our revolving credit facility. We have
access to an off-balance sheet operating lease facility that is used to finance
new store construction. The facility gives us up to $125.0 million of funding to
provide for the acquisition and development of 100 to 125 new stores over the
period of February 1, 1998 through May 31, 1999. As of November 1, 1998,
approximately $33.8 million of this $125.0 million leasing facility had been
committed. Our revolving credit facility provides for borrowings of up to $125.0
million, of which $66.0 million of unused capacity was available at November 1,
1998. We believe that cash flow from operations combined with the availability
of funds under the leasing facility and the revolving credit facility will be
sufficient to support our operations and liquidity requirements for the
foreseeable future.
    
 
     We opened 104 new, relocated or expanded stores in fiscal 1997 and 54 new,
relocated or expanded stores during the first half of fiscal 1998. We expect to
open, relocate or expand approximately 76 stores in the second half of fiscal
1998 (of which 34 were opened, relocated or expanded during the thirteen weeks
ended November 1, 1998) and approximately 150 stores in fiscal 1999. We
anticipate that the majority of these new, relocated or expanded stores will be
financed by sale-leaseback or similar arrangements structured as operating
leases that require no net capital expenditures except for fixtures and store
equipment. For the remainder of our planned new, relocated or expanded stores,
we expect to spend approximately $120,000 per store for leasehold improvements.
In addition to capital expenditures, each new store will require an estimated
investment in working capital, principally for inventories, of approximately
$300,000. A substantial portion of these inventories are expected to be financed
through vendor payables. New stores generally become profitable during the first
full year of operations. See note 1 to our consolidated financial statements.
 
                                       28
<PAGE>   30
 
     In addition to capital expenditures for new stores, we expect to spend
approximately $6.5 million over the next year for information systems hardware
and software (approximately $3.6 million of which is related to the "Year 2000"
issue discussed below).
 
     In fiscal 1997, net cash used in operating activities was $62.7 million,
which consisted primarily of $0.8 million of net loss, $22.4 million of non-cash
depreciation and amortization expenses, a $3.0 million non-cash extraordinary
loss and a $1.6 million decrease in deferred tax assets, offset by a $88.9
million increase in working capital. During this period, we used $63.8 million
of cash to increase inventory levels, primarily for funding new store openings
and for expanding the number of replacement parts offered in our stores. Net
cash used in investing activities totaled $56.7 million and consisted primarily
of $34.5 million for the purchase of 82 Trak West stores and $20.1 million of
capital expenditures. Net cash provided by financing activities totaled $119.1
million and consisted primarily of net borrowings under the Senior Credit
Facility and $21.7 million of equity contributions. At February 1, 1998, we had
approximately $25.8 million of net operating loss carryforwards available which
will reduce future cash requirements for the payment of federal income taxes.
 
   
     For the first half of fiscal 1998, net cash provided by operating
activities was $15.7 million which consisted primarily of $1.8 million of net
income, $11.9 million of non-cash depreciation and amortization expenses, a $5.0
million decrease in deferred tax assets and $10.4 million of non-cash losses and
write-off of deferred financing costs associated with the repayment of debt at
the time of the IPO, offset by $13.5 million used to fund working capital. Net
cash used in investing activities totaled $16.0 million and consisted primarily
of capital expenditures and assets held for sale under our new store development
program. Net cash provided by financing activities totaled $3.0 million and was
primarily related to our IPO and the repayment of debt using the net proceeds.
    
 
YEAR 2000 CONVERSION
 
     Historically, certain computerized systems have used two digits rather than
four to define the applicable year. Computer equipment and software and devices
with imbedded technology that are time-sensitive may recognize a date using "00"
as the year 1900 rather than the year 2000, resulting in system failures or
miscalculations. This problem is generally referred to as "the Year 2000 issue."
 
     Although we anticipate minimal business disruption will occur in our
systems as a result of the Year 2000 issue, possible consequences include a loss
of communications links with certain store locations, and the inability to
process transactions, send purchase orders, or engage in similar normal business
activities. We presently believe that with modifications to existing software
and conversions to new software, the risk of our Year 2000 conversion can be
mitigated. However, if we do not make the necessary modifications and
conversions, or do not complete them in a timely manner, it could have a
material adverse effect on our operations.
 
     During fiscal 1997, we began a comprehensive review of our systems and
applications for Year 2000 compliance. We also engaged an independent advisor to
evaluate and assist us with our Year 2000 program. To date, we have
substantially completed the identification and assessment phases of our Year
2000 conversion. We have included both information technology,
 
                                       29
<PAGE>   31
 
such as purchased software and point-of-sale computer systems, and
non-information technology equipment, such as warehouse conveyor systems, in our
evaluations. In addition, we have identified our key third-party business
partners and we are coordinating with them to address potential Year 2000
issues. These issues include data exchange with us as well as their shipping and
warehousing processes.
 
     We currently anticipate that our Year 2000 identification, assessment,
remediation and testing efforts, will be completed by July 31, 1999. To date, we
have incurred and expensed approximately $0.7 million related to the assessment
of and preliminary efforts in connection with our Year 2000 conversion project.
To date, we have also capitalized approximately $1.6 million in connection with
the replacement of certain hardware and software applications.
 
     The following table summarizes the time frame for the initiatives and the
estimated percent completed to date:

* Not yet commenced.
 
     We estimate the total remaining cost of our Year 2000 conversion to be $7.1
million, which is being funded with lease financing and operating cash flows. Of
the total project cost, we attribute approximately $3.6 million to the purchase
of new hardware and software which will be capitalized. We will expense the
remaining $3.5 million as incurred over the next two fiscal years.
 
     We have begun, but not yet completed, a comprehensive analysis of the
operational problems and costs (including loss of revenues) that would be
reasonably likely to result from our failure and the failure of certain third
parties to complete efforts necessary to achieve Year 2000 compliance on a
timely basis. We are developing a contingency plan to address Year 2000
failures.
 
   
     The costs of the Year 2000 Conversion and the date on which we plan to
complete the project are based upon our management's best estimates, which were
derived utilizing numerous assumptions of future events. We cannot guarantee
that we will achieve these estimates. Specific factors that could cause material
differences between our actual results and our estimates include: (1) the
availability and cost of personnel trained in this area; (2) the success of
third parties in their Year 2000 conversion plans; and (3) the ability to locate
and correct all relevant computer codes and similar uncertainties.

QUARTERLY RESULTS AND SEASONALITY
 
     Our business is somewhat seasonal in nature, with the highest sales
occurring in the summer months of June through August. Our business is, in
addition, affected by weather conditions. While unusually severe or inclement
weather tends to reduce sales as elective maintenance is deferred during such
periods, extremely hot and cold temperatures tend to enhance sales by causing
auto parts to fail and sales of seasonal products to increase.
 
     The following table sets forth certain quarterly unaudited operating data
for fiscal 1996, 1997 and the first half of fiscal 1998. The unaudited quarterly
information includes all adjustments which management considers necessary for a
fair presentation of the information shown.
 
     The data presented below should be read in conjunction with our
consolidated financial statements and related notes included elsewhere in this

(1) Operating profit in the fourth quarter of fiscal 1996 was negatively
    affected by non-recurring charges of $20.2 million related to the 1996
    Recapitalization (see note 2 to our consolidated financial statements) as
    well as by a provision for store closing costs totaling $12.9 million (see
    note 12 to our consolidated financial statements).
 
(2) Net income in the fourth quarter of fiscal 1996 was negatively affected by
    non-recurring charges of $12.5 million related to the 1996 Recapitalization
    (see note 2 to our consolidated financial statements) as well as by the
    charges discussed in note (1) above, net of income taxes. (see note 12 to
    our consolidated financial statements).
 
(3) The sum of the quarterly earnings (loss) per share amounts within a fiscal
    year differ from the total earnings (loss) per share for the fiscal year or
    first half of the fiscal year due to the impact of differing weighted
    average share outstanding calculations.
 
(4) Operating profit in the fourth quarter of fiscal 1997 was negatively
    affected by $3.4 million of transition and integration expenses related to
    the acquisition of 82 former Trak West stores and by $0.9 million of
    stock-based compensation.
 
(5) Net income in the fourth quarter of fiscal 1997 was negatively affected by
    an extraordinary loss of $3.0 million related to the write-off of the
    deferred financing costs associated with the early retirement of debt as
    well as by the charges discussed in note (4) above, net of income taxes.
 
(6) Operating profit in the first quarter of fiscal 1998 was negatively affected
    by non-recurring charges of $3.1 million related to the transition and
    integration of the 82 Trak West stores (see note 2 to our consolidated
    financial statements) and the $3.6 million write-off of the remaining
    unamortized balance of a pre-paid management consulting and advisory
    services agreement that terminated by its terms upon consummation of our
    IPO.
 
(7) Net income in the first quarter of fiscal 1998 was negatively affected by a
    $6.8 million extraordinary loss, net of $4.2 million of income taxes, which
    consisted of prepayment premiums paid in connection with redemption of debt
    and the write-off of a portion of deferred debt issuance costs, as well as
    by the charges discussed in note (6) above, net of income taxes.

INFLATION
 
     We do not believe our operations have been materially affected by
inflation. We believe that we will be able to mitigate the effects of future
merchandise cost increases principally through economies of scale resulting from
increased volumes of purchases, selective forward buying and the use of
alternative suppliers.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information." In February 1998, the FASB issued SFAS
No. 132, "Employers Disclosures about Pensions and Other Postretirement
Benefits." We will adopt these statements during fiscal 1998. As these
statements only require additional disclosures in our financial statements,
their adoption will not have any effect on our financial position or results of
operations.
 
   
     In March 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants issued Statement of Position ("SOP")
98-1, "Accounting for the Cost of Computer Software Developed or Obtained for
Internal Use." The SOP defines the characteristics of internal-use computer,
software criteria for capitalization, and financial statement disclosure
requirements. We will adopt SOP 98-1 in fiscal 1999 and do not expect that such
adoption will have a material effect on our financial position or results of
operations.
    
 
     In April 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants issued SOP 98-5, "Reporting on the
Cost of Start-up Activities." The SOP broadly defines start-up activities as
those one-time activities related to opening a new facility, introducing a new
product or service, conducting business in a new territory, or commencing some
new operation. The SOP requires that the costs of start-up activities be
expensed as incurred. Our current accounting policy with respect to the cost of
start-up activities is to defer such costs for the approximately three month
period of time that it takes to develop a new store facility and to expense such
costs during the month that the new store opens. We will adopt SOP 98-5 in
fiscal 1999, which will require us to change our current accounting policy to
expense start-up costs as incurred. We do not believe that the impact of
adoption will have a material effect on our financial position or results of
operations.

                                    BUSINESS
 
     We are the largest retailer of automotive parts and accessories in the
Western United States and one of the largest retailers of such products in the
United States based, in each case, on our number of stores. As of November 1,
1998, we operated 773 stores as one fully integrated company under three brand
names:
 
     - Checker Auto Parts, founded in 1968 and operating in the Southwestern and
       Rocky Mountain states;
 
     - Schuck's Auto Supply, founded in 1917 and operating in the Pacific
       Northwest; and
 
     - Kragen Auto Parts, founded in 1947 and operating primarily in California.
 
     Based on our store count, we believe we are the largest retailer of
automotive parts and accessories in 19 of our 24 markets.
 
     We offer a broad selection of national brand name and private label
automotive products for domestic and imported cars, vans and light trucks. Our
products include new and remanufactured automotive replacement parts,
maintenance items and accessories. Most of our sales are to do-it-yourself
customers, although our commercial sales program focusing on sales to auto
repair professionals and fleet owners, represents a significant and increasing
part of our business. Our stores typically offer between 13,000 and 17,000 SKUs.
Our operating strategy is to offer our products at everyday low prices and at
conveniently located and attractively designed stores, supported by highly
trained, efficient and courteous customer service personnel. We do not sell
tires or perform automotive repairs.
 
OPERATING AND GROWTH STRATEGIES
 
     Over the past several years, we have implemented a variety of operating
initiatives which have enabled us to significantly increase our productivity and
the level and quality of service we provide to our customers.
 
     These operating initiatives include:
 
     - EXPANDED PRODUCT SELECTION -- Our priority parts operation permits us to
       better serve our do-it-yourself and commercial customers by making
       available to more than 80% of our stores, on a same-day delivery basis,
       an additional 200,000 SKUs not regularly stocked in these stores, and on
       a next-day delivery basis to all of our stores, an additional 1,000,000
       SKUs. We have expanded our priority parts operation by improving our
       delivery system and adding 30 strategically located priority parts depots
       to our two original priority parts depots. We believe that our priority
       parts operation provides us with an important competitive advantage.
 
     - IMPROVED WAREHOUSE AND DISTRIBUTION SYSTEM -- We have converted our
       warehouse and distribution facilities from a manual, labor-intensive,
       paper-based system to a technologically advanced, fully-integrated
       system. This system became fully operational during the fourth quarter of
       fiscal 1995 and has improved our in-stock levels and order fulfillment
       accuracy to the highest rates in recent years. We have reduced warehouse
       and distribution expense as a percentage of net sales from 4.9% for
       fiscal 1995 to 3.8% for fiscal 1996,
 
                                       34
<PAGE>   36
 
       3.4% for fiscal 1997 and 3.3% for the first half of fiscal 1998. We
       believe we have sufficient warehouse and distribution capacity to meet
       the requirements of our growth plans for the foreseeable future.
 
     - ENHANCED STORE-LEVEL INFORMATION SYSTEMS -- We have installed several
       sophisticated store-level information systems which have improved store
       labor productivity and customer service. These enhanced information
       system capabilities have also enabled us to achieve higher average
       transaction amounts by providing employees with the information they need
       to suggest appropriate add-on products, including higher margin
       replacement parts. In addition, the significant investment we have made
       in information systems has played an important role in our successful
       penetration of the commercial market.
 
     - TRAINING AND TECHNICAL EXPERTISE -- We have increased our focus on formal
       classroom training and on-the-job training, customer service measurement
       systems and incentive programs for our district managers, store managers,
       and sales staff. Approximately 1,500 of our employees have passed the
       ASE-P2 test, a nationally recognized certification for parts technicians.
       We believe these programs have resulted in an increased level of customer
       service and store-level efficiency.
 
     - CENTRALIZED CALL CENTER -- Our centralized call center provides store
       personnel at selected high-volume stores the option to reroute customer
       calls to a central location during the store's busiest hours of
       operation. Use of the call center allows sales associates to give their
       undivided attention to customers at the store while call-in customers are
       serviced directly by call center associates.
 
     - PRECISION PRICING PROGRAM -- During fiscal 1997, we implemented a pricing
       program, which allows us to establish pricing zones at the store level
       rather than the market or chain level. This initiative enables us to
       establish pricing levels for each store based upon that store's local
       market competition.
 
     These operating initiatives have provided us with a highly efficient,
centralized infrastructure and the foundation for continued and profitable
growth. We are currently generating growth in sales and operating profits
primarily by implementing the following growth initiatives:
 
     - ACCELERATING STORE GROWTH STRATEGY -- Our store growth strategy is
       focused on existing markets and includes:
 
          - opening new stores;
 
          - relocating smaller stores to larger stores at better locations; and
 
          - expanding selected stores.
 
       Our existing markets have many competitors with fewer stores than we
       have. We believe that our store growth strategy will enable us to
       effectively and profitably increase our name recognition and market
       penetration while benefiting from economies of scale in advertising,
       management and distribution costs. In addition to the 82 Trak West stores
       we acquired in the Los Angeles market in December 1997 from Trak Auto
       Corporation, we opened, relocated or expanded 104 stores in fiscal 1997
       compared to 64 stores in fiscal 1996. We plan to continue to accelerate
       our store growth strategy and expect to open,
 
                                       35
<PAGE>   37
 
   
       relocate or expand a total of 130 stores in fiscal 1998 (88 have already
       been opened, relocated or expanded as of November 1, 1998) and
       approximately 150 stores in fiscal 1999. We believe that the large number
       of small operators in our industry enables us to effectively pursue an
       opportunistic acquisition strategy. Our acquisition strategy focuses on
       (1) existing markets to achieve further market penetration in a timely
       and cost-effective manner without adding additional retail square footage
       (as was done in the Trak West Acquisition), and (2) contiguous markets,
       to permit further leveraging of our established infrastructure over an
       increasing sales base.
    
 
     - EXPANDING COMMERCIAL SALES PROGRAM -- We believe that we can continue to
       expand our profitable and highly successful commercial sales program for
       auto repair professionals and fleet owners. The commercial market
       constitutes in excess of 50% of the approximately $78 billion of annual
       sales in the automotive aftermarket and is currently growing at a faster
       rate than the do-it-yourself market. We believe we have significant
       competitive advantages in servicing the commercial customer because of
       our experienced sales associates, conveniently located stores, attractive
       pricing and ability to consistently deliver a broad product offering with
       an emphasis on national brand names. Commercial sales centers have been
       implemented in 467 of our stores as of November 1, 1998. Our sales to
       commercial accounts (including sales by stores without commercial sales
       centers) have increased 30% to $74.9 million in the first half of fiscal
       1998, from $57.7 million in the comparable period in fiscal 1997. We
       believe that significant opportunities exist to increase sales at our
       existing commercial sales centers by focusing on the penetration of
       certain sectors of the commercial market such as fleet owners,
       municipalities and national accounts. We intend to continue installing
       commercial sales centers in selected existing stores and in approximately
       half of our new stores. We have already installed commercial sales
       centers in 43 of the acquired Trak West stores (which did not actively
       pursue commercial customers before we acquired them).
 
     - INCREASING OPERATING PROFIT MARGIN -- We have increased our operating
       margin to 6.2% in the first half of fiscal 1998, from 4.6% in the
       comparable period of fiscal 1997. Excluding $6.7 million of non-recurring
       charges, our operating profit margin for the first half of fiscal 1998
       was 7.5%. Our gross profit margin is increasing primarily as a result of
       more favorable vendor terms, taking advantage of cash discounts from
       vendors, and improvements in our product mix. We believe that the
       improved vendor terms are primarily the result of our improved financial
       performance and stronger capitalization, a reduction in overall vendor
       payables and growth in our store count. We believe that we can further
       improve our operating profit margin through the continued focus on our
       operating initiatives described above, and effectively leveraging our
       fixed costs over an increasing sales base.
 
     The success of our operating and growth initiatives has resulted in a 58%
increase in operating profit to $30.2 million for the first half of fiscal 1998,
from $19.1 million in the comparable period in fiscal 1997. Excluding $6.7
million of non-recurring charges, operating profit for the first half of fiscal
1998 was $36.9 million, an increase of 93% over the comparable period of fiscal
1997. We believe that we can continue to realize strong and profitable growth by
aggressively pursuing our operating and growth initiatives.

AUTOMOTIVE AFTERMARKET INDUSTRY
 
     We are a retailer of aftermarket automotive products such as replacement
parts, maintenance items and accessories. The term aftermarket distinguishes our
sales from those items sold as part of the original sale of a car or truck.
According to industry estimates, the size of the automotive aftermarket for
replacement parts, maintenance items and accessories was approximately $78
billion in sales in 1996. We believe that the automotive aftermarket for these
items is growing because of increases in:
 
     - the size and age of the country's automotive fleet;
 
     - the number of miles driven annually per vehicle;
 
     - the purchase prices of new cars;
 
     - the cost of replacement parts; and
 
     - labor costs associated with parts, installation and maintenance.
 
     There are many companies selling automotive aftermarket products. We
believe, however, that the industry is consolidating as national and regional
specialty retail chains gain market share at the expense of smaller independent
retailers and less specialized mass merchandisers. Automotive specialty
retailing chains like ours, which have multiple locations in a given market
area, enjoy competitive advantages in purchasing, distribution, advertising and
marketing compared to most small independent retailers. In addition, the recent
significant increase in the variety of domestic and imported vehicle makes and
models has increased the number of automotive replacement parts. This makes it
difficult for smaller independent retailers and less specialized mass
merchandise chains to maintain inventory selection broad enough to meet customer
demands. We believe this has created a competitive advantage for us and for
other automotive specialty retailing chains that have the distribution capacity
and sophisticated information systems to stock and deliver a large number of
products in a timely manner.
 
THE TRAK WEST ACQUISITION
 
     On December 8, 1997, we acquired 82 stores located in the Los Angeles
market that had been owned by Trak Auto Corporation. The acquisition of these
stores provides us with a much greater presence (as of November 1, 1998, a total
of 157 stores) in the large, strategically important Los Angeles market, without
increasing the number of competing stores in the market. We completed the
conversion of these stores to our Kragen name and store format and the
integration of these stores into our operations during the first quarter of
fiscal 1998.
 
MARKETING AND MERCHANDISING STRATEGY
 
     Our marketing and merchandising strategy is to build market share by
providing a broad selection of national brand name and private label products at
everyday low prices. We offer these products at conveniently located and
attractively designed stores, staffed by highly trained, efficient and courteous
employees.
 
                                       37

CUSTOMER SERVICE
 
     We are a customer-oriented retailer dedicated primarily to do-it-yourself
consumers with a significant and increasing focus on commercial customers. We
try to enhance customer service by use of our sophisticated product distribution
and store support systems, as well as our extensive training programs.
 
     We believe that the recruiting, training and retaining of high quality
sales employees is required if our business is to be successful. We operate
training and incentives programs to encourage the development of technical
expertise by our sales employees so they can effectively advise customers on
product selection and use. Well trained employees not only provide a high level
of customer satisfaction, they increase productivity and reduce labor costs.
 
     CSK University, our sales employee development program, is dedicated to the
continuous education of store associates through structured on-the-job training
and formal classroom instruction. The curriculum focuses on four areas of the
employee's development:
 
     - customer service skills;
 
     - basic automotive systems;
 
     - advanced automotive systems; and
 
     - management development.
 
     Much of the training is delivered through formal classes in 16 training
centers that are fully equipped with the same systems as are in our stores. We
believe that our training programs enable sales associates to provide a high
level of service to a wide variety of customers ranging from less informed
do-it-yourself consumers to more sophisticated purchasers requiring diagnostic
advice. We also provide continuing training programs for store managers and
district managers designed to assist them in increasing store-level efficiency
and improving their potential for promotion. In addition, we require periodic
meetings of district and store managers to facilitate and enhance communications
within our organization. Approximately 1,500 of our employees have passed the
ASE-P2 test, a nationally recognized certification for parts technicians.
 
     In order to satisfy our customers, we adopted several service initiatives
including free testing of starters, alternators and batteries; free charging of
batteries; installation assistance for batteries, windshield wipers and other
selected products; "no hassle" return policies; and electronically maintained
lifetime warranties, which eliminate the need for consumer record keeping. Our
significant investments in employee training and store-level information systems
enable our in-store personnel to devote more time to attending to our customers'
automotive needs.
 
     We use our centralized database as a source to make approximately 72,000
calls annually to customers inquiring as to their overall satisfaction with our
sales employees, pricing, product selection and quality. In addition, the
results of customer satisfaction surveys are provided to each store and the
appropriate management personnel to ensure that customer service levels remain a
store focus.
 
                                       38
<PAGE>   40
 
PRODUCT SELECTION
 
   
     Our stores have a broad selection of national brand name products in order
to generate customer traffic and appeal to our commercial customers. In
addition, we stock a large selection of high quality private label products that
appeal to value-conscious customers. Each store offers an extensive product
line, including automotive replacement parts such as starters, alternators,
shock absorbers, mufflers, brakes, spark plugs, filters and batteries, as well
as a wide variety of maintenance items, such as motor oil, lubricants, waxes,
cleaners, polishes and antifreeze. In addition, each store offers general
accessories such as car stereos, alarms, trim, floor mats, tools and seat
covers. Sales of replacement parts account for approximately 60% of our sales.
Replacement parts typically generate higher gross profit margins than
maintenance items or general accessories. We are increasing our sales of
replacement parts, as a percentage of total sales, by offering a wider selection
of replacement parts and by increasing sales to commercial customers.
    
 
PRODUCT AVAILABILITY
 
     Our stores offer between 13,000 and 17,000 SKUs of national brand name and
private label automotive products. If a store does not carry a specific part,
store employees are able to use our surround store inventory program to record
the sale, reserve the part and direct the customer to pick it up from a store in
the same market or at one of our nearby depots.
 
     We have continued to expand and improve our delivery system and have
increased our number of strategically located priority parts depots to 32. This
has led to better customer service by making available up to an additional
200,000 products on a same-day delivery basis to over 80% of our stores and
1,000,000 additional products on a next-day delivery basis to all of our stores.
This has also allowed us to increase sales to commercial accounts due to
availability of a greater number of replacement parts. Prior to this improvement
and expansion, this same day delivery service was available to only 80 of our
stores. Our priority parts operation handles approximately 120,000 inquiries
each week. Store associates are able to electronically inquire on price and
availability and order parts from the priority parts depots through our
electronic parts catalog and receive immediate confirmation of availability
without having to make telephone inquiries. We believe that these programs
provide us with important competitive advantages.
 
     We have classified our product mix into 110 separate categories through a
merchandising program designed to determine the optimal inventory mix at each
individual store based on that store's historical sales. We believe that we can
improve store sales, gross profit margin and inventory turnover by tailoring
individual store inventory mix based on historical sales patterns for each of
the 110 product categories.
 
PRICING
 
     Our pricing philosophy is that we should not lose a customer because of
price. Our pricing strategy is to offer everyday low prices at each of our
stores. Part of this strategy is to beat any competitor's lower price by 5%. As
a result, we closely monitor our competitors' pricing levels to ensure
competitive pricing in all of our stores. Our entry-level products offer
excellent value by meeting standard quality requirements at low prices. In
addition, our sales associates are
 
                                       39
<PAGE>   41
 
encouraged to offer alternative products at slightly higher price points. These
products typically provide extra features, improved performance, an enhanced
warranty or are of national brand recognition.
 
     In the third quarter of fiscal 1997, we implemented our precision pricing
program which analyzes prices at the store level rather than at the market or
chain level. This initiative enables us to establish pricing levels at each
store based upon that store's local market competition.
 
ADVERTISING
 
     We support our marketing and merchandising strategy through print
advertising, in-store promotional displays and an increasing emphasis on radio
and television advertising. The print advertising consists of monthly color
circulars produced by our in-house advertising department and which contain
redeemable coupons. We also advertise on radio, television and billboards
primarily to reinforce our image and name recognition. Television advertising is
targeted to sports programming and radio advertising primarily is aired during
commuting hours. Advertising efforts include Spanish language television and
radio as well as bilingual store signage. In-store signs and displays are used
to promote products, identify departments, and to announce store specials. We
also sponsor a National Hot Rod Association Funny Car. We have web sites on the
Internet at:
 
     - http://www.checkerauto.com;
 
     - http://www.schucks.com; and
 
     - http://www.kragen.com.
 
STORE-BASED INFORMATION SYSTEMS
 
     Over the past several years, we installed several store-level information
systems, which have improved store labor productivity and customer service.
These systems are described below.
 
  ELECTRONIC PARTS CATALOG
 
     Our electronic parts catalog is a software-based system that identifies the
location and availability of over one and a half million parts. The electronic
parts catalog is a user-friendly tool that enables our sales associates to
assist customers in parts selection and ordering based on simple input of the
year, model and engine type and application needed. The electronic parts catalog
covers vehicles with model years from 1967 through 1998. Once provided with this
basic information, the electronic parts catalog displays which part is needed
and whether it is located in the store. In the event a particular product is
unavailable at a store, the electronic parts catalog indicates whether it can be
obtained at a nearby store, priority parts depot, through certain warehouse
distributors with same-day delivery or directly from the manufacturer.
Information about the customer's car can be entered into a permanent customer
database that can be instantly accessed whenever the customer visits or phones
the store. The electronic parts catalog also displays related parts that the
sales associates can recommend to the customer for purchase and prints parts
lists for the customer. Our electronic parts catalog system is integrated
 
                                       40
<PAGE>   42
 
with our point of sale system and centralized database. This integration
improves customer service by:
 
     - reducing check-out time by fully automating the ordering process between
       the parts counter and the point of sale register;
 
     - allowing the store associate to order parts electronically with immediate
       confirmation of availability and/or delivery; and
 
     - providing up-to-the-minute pricing of products.
 
  POINT OF SALE SYSTEM
 
     We installed a point of sale system consisting of cash registers and
sophisticated software in all of our stores, which electronically record and
report customer transactions and are tied to our electronic parts catalog and
the central inventory system. This point of sale system improves store
productivity and customer service by streamlining in-store procedures and
eliminating handwritten record keeping. This system also allows for paperless
transactions and electronic updating of warranty information. In addition, the
point of sale software tracks the history of individual customer purchases,
allowing us to monitor customer activity for use in regionalized marketing and
merchandising programs.
 
  RETAIL PAPERLESS MANAGEMENT SYSTEM
 
     Our retail paperless management system is a store-based software system
used to improve store efficiency. This system provides for interactive store
associate development and testing, communication via company-wide e-mail,
knowledge-based interviewing of associate applicants, automated associate time
and attendance recording and forms automation.
 
  LABOR SCHEDULING SYSTEM
 
     We utilize a sophisticated labor scheduling system that allocates labor
hours based on factors including forecasted sales and customer traffic counts.
We believe this system enables us to provide superior customer service while
providing for improved labor productivity.
 
  SATELLITE COMMUNICATIONS NETWORK
 
     Our satellite communications network links all of our stores with our
corporate office. The satellite network enables us to efficiently obtain and
deliver to our stores all file transfers, including pricing down-loads, sales
information updates and interactive transactions such as electronic parts
ordering. The system also broadcasts common files to all stores simultaneously
to update our electronics parts catalog. In addition, the satellite network
significantly increases the speed of credit card and check authorization.
 
  CALL CENTER
 
     Our centralized call center provides store personnel at selected
high-volume stores the option to reroute customer calls to a central location
during the store's busiest hours of operation. Call center associates perform
all functions that store personnel normally handle, such as store
 
                                       41
<PAGE>   43
 
specific parts look-up, price look-up and inventory availability verification.
Associates in the call center can take an order from a customer and
electronically transmit it to the store, so that the customer can pick up the
requested product at his local store. Use of the call center allows sales
associates to give their undivided attention to customers at the store while
call-in customers are serviced directly by call center associates.
 
STORE OPERATIONS
 
     Our stores are divided into seven geographic regions: Southwest, Rocky
Mountain, Northwest, Southern California, Coastal California, Los Angeles and
Northern California. Each region is administered by a regional manager, each of
whom oversees seven to ten district managers. Each of our district managers has
responsibility for between 11 and 18 stores.
 
     The geographic distribution of our stores and the tradenames under which
they operated, as of November 1, 1998, are set forth in the table below.

     Our stores are generally open seven days a week, with hours from 8:00 a.m.
to 9:00 p.m. (9:00 a.m. to 6:00 p.m. on Sundays). Each store employs
approximately 10 to 20 employees, including a store manager, two assistant store
managers and a staff of full-time and part-time employees.
 
STORE FORMATS
 
   
     Our stores are generally located in high visibility, high traffic strip
shopping centers or in freestanding units adjacent to strip shopping centers.
The stores, which range in size from 2,800 to 27,000 square feet, average
approximately 6,900 square feet in size and offer between 13,000 and 17,000
SKUs.
    
 
     We have four prototype store designs which are 6,000, 7,000, 8,000 and
12,000 square feet in size. The store size for a given new location is selected
based upon sales volume expectations determined through demographics and the
detailed market analysis that we prepare as part of

     Approximately 60% of our stores are freestanding, with the balance
principally located within strip shopping centers. Approximately 85% to 90% of
each store's square footage is selling space, of which approximately 40% to 50%
is dedicated to automotive replacement parts inventory. The replacement parts
inventory area is fronted by a counter staffed by knowledgeable parts personnel
and is equipped with the electronic parts catalog. The remaining selling space
contains gondolas for accessories and maintenance items, including oil and air
filters, additives, waxes and other items, together with specifically designed
shelving for batteries and, in many stores, oil products.
 
STORE GROWTH STRATEGY
 
     Our store growth strategy is focused on our existing markets and includes:
 
     - opening new stores;
 
     - relocating smaller stores to larger stores at better locations; and
 
     - expanding selected stores.
 
     We have identified most of our stores smaller than 5,000 square feet as
future relocation or expansion priorities.
 
     Our market strategy group, which is a part of our real estate department,
utilizes a sophisticated, market-based approach that identifies and analyzes
potential store locations based on detailed demographic and competitive studies.
These demographic and competitive studies include analysis of population
density, growth patterns, age, ethnicity, per capita income, vehicle traffic
counts, and the number and type of existing automotive-related facilities, such
as automotive parts stores and other competitors within a pre-determined radius
of the potential new location. These potential locations are compared to our
existing locations to determine opportunities for opening new stores and
relocating or expanding existing stores.
 
     We believe that the large number of small operators in our industry has
enabled us to effectively pursue an opportunistic acquisition strategy. We focus
our acquisition efforts in (1) existing markets to achieve further market
penetration in a timely and cost-effective manner without adding additional
retail square footage (as we avoided doing in the Trak West Acquisition), and
(2) contiguous markets to permit further leveraging of our established
infrastructure over an increasing sales base.

</TABLE>
 
     We believe that substantial growth opportunities exist in our current
markets and that our store growth strategy will increase our name recognition
and market penetration while benefiting from economies of scale in advertising,
management and distribution costs. In addition to the Trak West Acquisition, we
opened, expanded or relocated 104 stores in fiscal 1997 as compared to 64 stores
in fiscal 1996. We plan to continue to accelerate our store growth strategy and
expect to open, relocate or expand approximately 130 stores in fiscal 1998 (88
have already been opened, relocated or expanded as of November 1, 1998) and
approximately 150 stores in fiscal 1999. As of November 1, 1998, we had executed
purchase contracts or leases for 68 sites, were in various stages of negotiation
for 76 additional sites and had identified numerous potential additional sites
for store growth. New stores generally become profitable during the first year
of operation.
 
COMMERCIAL SALES PROGRAM
 
     In addition to our primary focus on serving the do-it-yourself consumer, we
have significantly increased our marketing efforts to the commercial customer in
the automotive replacement parts market. The commercial market constitutes in
excess of 50% of the annual sales in the automotive aftermarket and is currently
growing at a faster rate than the do-it-yourself market. Our commercial sales
program, which is intended to facilitate penetration of this market, is targeted
to professional mechanics, auto repair shops, auto dealers, fleet owners, mass
and general merchandisers with auto repair facilities and other commercial
repair outlets located near our stores.
 
     We have made a significant commitment to this portion of our business, and
upgraded the information systems capabilities available to the commercial sales
group. In addition, we employ one district sales manager for approximately every
five stores that have a commercial sales center. A district sales manager is
responsible for servicing existing commercial accounts and developing new
commercial accounts. In addition, each commercial sales center has a dedicated
in-store salesperson, driver and delivery vehicle.
 
                                       44
<PAGE>   46
 
     We believe we are well positioned to effectively and profitably service
commercial customers, who typically require a high level of customer service and
broad product availability. The commercial market has traditionally been
serviced primarily by jobbers. Recently, however, automotive specialty retailing
chains, such as our company, have entered the commercial segment. The chains
typically have multiple locations in given market areas and maintain a broad
inventory selection. We believe we have significant competitive advantages in
servicing the commercial market because of our experienced sales associates,
conveniently located stores, attractive pricing and ability to consistently
deliver a broad product offering with an emphasis on national brand names.
 
     At September 30, 1994, we operated commercial sales centers in five of our
stores and as of November 1, 1998, we operated commercial service centers in 467
of our stores. Our sales to commercial accounts (including sales by stores
without commercial service centers) have increased 30% to $74.9 million in the
first half of fiscal 1998 from $57.7 million in the comparable period in fiscal
1997.
 
   
     We intend to continue to expand our successful marketing efforts to the
commercial segment of the automotive aftermarket. We believe that significant
opportunities exist to increase sales at our existing commercial sales centers
by focusing on the penetration of certain sectors of the commercial market such
as fleet owners, municipalities and national accounts. We intend to continue
installing commercial sales centers in selected existing stores and in
approximately half of our new stores. We have already installed commercial
service centers in 43 of the recently acquired Trak West stores (which did not
actively pursue commercial customers before we acquired them).
    
 
PURCHASING
 
     Merchandise is selected and purchased for all stores by personnel at our
corporate headquarters in Phoenix, Arizona from over 300 suppliers. No one class
of product and no single supplier accounted for as much as 10% of our purchases
in fiscal 1997.
 
     Our inventory management systems include the E-3 Trim Buying System, which
provides inventory movement forecasting based upon history, trend and
seasonality. Combined with service level goals, vendor lead times and cost of
inventory assumptions, the E-3 Trim Buying System determines the timing and size
of purchase orders. Approximately 90% of the dollar value of transactions are
sent via electronic data interchange, with the remainder being sent by a
computer facsimile interface. Our store replenishment system generates orders
based upon store on-hand and store model stock. This includes an automatic model
stock adjustment system utilizing historical sales, seasonality and store
presentation requirements. We also can allocate seasonal and promotional
merchandise based upon a store's history of prior promotional and seasonal
sales.
 
     Our stores offer products with nationally recognized, well-advertised brand
names, such as Armor All, Autolite, AC Delco, Castrol, Dayco, Exide, Fel Pro,
Fram, Havoline, Mobil, Monroe, Pennzoil, Prestone, Quaker State, RayBestos,
Slick 50, Stant, Sylvania, Turtle Wax and Valvoline. In addition to brand name
products, our stores carry a wide variety of high quality private label
products. Because most of such products are produced by nationally recognized
 
                                       45
<PAGE>   47
 
manufacturers that produce similar brand name products that enjoy a high degree
of consumer acceptance, we believe that our private label products are of a
quality that is comparable to such brand name products.
 
     We have increased our gross profit margin over the last several years
primarily as a result of more favorable vendor terms, taking advantage of cash
discounts from vendors, efficiencies from our new warehouse and distribution
system and improvements in product mix. We believe that the improved vendor
terms are primarily the result of our improved financial performance and
stronger capitalization, a reduction in overall vendor payables and growth in
our store count. Our gross profit margin increased from 39.6% in fiscal 1995 to
45.7% for the first half of fiscal 1998 and we believe we have the opportunity
to continue realizing higher gross profit margins.
 
WAREHOUSE AND DISTRIBUTION
 
     We successfully converted our warehouse and distribution system from a
manual, labor intensive, paper-based system to a technologically advanced,
fully-integrated system. This system, which became operational in the fourth
quarter of fiscal 1995, has improved our in-stock levels and order fulfillment
accuracy to the highest rates in recent years. We have reduced warehouse and
distribution expenses as a percentage of net sales from 4.9% for fiscal 1995 to
3.8% for fiscal 1996, 3.4% for fiscal 1997, and 3.3% for the first half of
fiscal 1998. We have sufficient warehouse and distribution capacity to meet the
requirements of our growth plans for the foreseeable future.
 
     Our new system utilizes bar coding, radio frequency scanners and
sophisticated conveyor and put-to-light systems. We instituted engineered labor
standards and incentive programs in each of our distribution centers which have
contributed to improved labor productivity. Each store is currently serviced by
one of our two main distribution centers, with the regional distribution centers
handling bulk materials, such as oil received directly from vendors. All of our
merchandise is shipped by vendors to our distribution centers, with the
exception of batteries, which are shipped directly to stores by the vendor.
 
     The following table sets forth certain information relating to our two main
distribution centers as of November 1, 1998:

MANAGEMENT INFORMATION SYSTEMS
 
     Our management information systems are an important element of our
operations and growth strategy. We use one Hitachi Data System EX33 Mainframe,
four IBM AS/400's ("AS/400") and over 400 personal computers which are connected
to a local area network. A satellite communications network provides the link
from our centralized database to the stores. We are currently upgrading these
systems, as necessary, to be "Year 2000" compliant.
 
     Our store-based information systems are on a UNIX based platform with full
connectivity between the electronic parts catalog and the point of sale systems.
This includes electronic ordering from our electronic parts catalog via the
corporate office AS/400 to our priority parts depots, third-party warehouse
distributors and directly to vendors.
 
EMPLOYEES
 
     As of November 1, 1998, we employed approximately 7,200 full-time employees
and 3,500 part-time employees. Approximately 85% of these personnel are employed
in store level operations, 8% in distribution and 7% in our corporate
headquarters, including our call center and priority parts operation.
 
     We have never experienced any material labor disruption and believe that
our labor relations are very good. Except for 482 employees located at
approximately 40 stores in the San Jose, California market, who have been
represented by a union for more than 18 years, none of our personnel are
represented by a labor union.

COMPETITION
 
     We compete principally in the do-it-yourself sector of the automotive
aftermarket which is highly fragmented and generally very competitive. We
compete primarily with national and regional retail automotive parts chains
(such as AutoZone, Inc. and The Pep Boys-Manny, Moe and Jack, Inc.), wholesalers
or jobber stores (some of which are associated with national automotive parts
distributors or associations, such as NAPA), automobile dealers, and mass
merchandisers that carry automotive replacement parts, maintenance items and
accessories (such as Wal-Mart Stores, Inc.). We believe that chains of
automotive parts stores like ours, with multiple locations in regional markets,
have competitive advantages in marketing, product selection, purchasing and
distribution, as compared to independent retailers and jobbers that are not part
of a chain or associated with other retailers or jobbers. We believe that, as a
result of these advantages, national and regional chains have been gaining
market share in recent years at the expense of independent retailers and
jobbers.
 
     The principal competitive factors that affect our business are store
location, customer service, product selection, availability, quality and price.
While we believe that we compete effectively in our various geographic areas,
certain competitors are larger in terms of sales volume, have greater financial
and management resources and have been operating longer in certain geographic
areas.
 
TRADE NAMES, SERVICE MARKS AND TRADEMARKS
 
     We own and have registered the service mark "Schuck's" with the United
States Patent and Trademark Office for use in connection with the automotive
parts retailing business. We have the right to use the tradenames "Checker" (in
connection with the automotive parts retailing business in the West and
Southeast regions of the United States) and "Kragen." In addition, we own and
have registered numerous trademarks with respect to many of our private label
products. We believe that our various tradenames, service marks and trademarks
are important to our merchandising strategy, but that our business is not
otherwise dependent on any particular service mark, tradename or trademark.
There are no infringing uses known by us that materially affect the use of such
marks.

ENVIRONMENTAL MATTERS
 
     We are subject to various federal, state and local laws and governmental
regulations relating to the operation of our business, including those governing
recycling of batteries and used lubricants, and regarding ownership and
operation of real property. We handle hazardous materials during our operations,
and our customers may also bring or use hazardous materials or used oil onto our
properties. In addition, while we do not service automobiles, we do sublease to
third parties pre-existing service bays at a small number of store locations.
These third parties are required to dispose of certain items, including used
batteries, lubricants and oils in accordance with applicable environmental
regulations. We currently provide a recycling program for batteries and for the
collection of used lubricants at certain of our stores as a service to our
customers pursuant to agreements with third-party vendors. Pursuant to the
agreements, the batteries and used lubricants are collected by our employees,
deposited into vendor-supplied containers/pallets and then disposed of by the
third-party vendors. Our agreements with such vendors are designed to limit our
potential liability under applicable environmental regulations for any harm
caused by the batteries and lubricants to off-site properties or even on-site
when such failure is the fault of the vendor. Many of the agreements provide us
with indemnification against liability that we may incur in connection with the
disposal of such items.
 
     Under environmental laws, a current or previous owner or operator of real
property may be liable for the cost of removal or remediation of hazardous or
toxic substances on, under, or in such property. Such laws often impose joint
and several liability and may be imposed without regard to whether the owner or
operator knew of, or was responsible for, the release of such hazardous or toxic
substances. We do not believe that compliance with such laws and regulations has
had a material impact on our operations to date, but there can be no assurance
that future compliance with such laws and regulations will not have a material
adverse effect on us.
 
LEGAL PROCEEDINGS
 
   
     We were served with a lawsuit that was filed in the Superior Court in San
Diego, California on May 4, 1998. The case is brought by two former store
managers and a former assistant manager. It purports to be a class action for
all present and former California store managers and senior assistant managers
and seeks overtime pay for a period beginning in May 1995 as well as injunctive
relief requiring overtime pay in the future. This case is in the early stages of
discovery. We were recently served with two other lawsuits purporting to be
class actions filed in California state courts in Orange and Fresno Counties by
thirteen other former and current employees. These lawsuits include similar
claims to the San Diego lawsuit, except that they also include claims for unfair
business practices and the Orange County lawsuit includes a claim for punitive
damages based on an unlawful conversion theory. If these cases are permitted by
the courts to proceed as a class action and are decided against us, our
aggregate potential exposure could be material to our results of operations for
the year in which the cases are ultimately decided. We do not believe, however,
that such an adverse outcome, if it were to happen, would materially affect our
financial position or our operations in subsequent periods. Although at this
early stage in the litigation it is difficult to predict its outcome with any
certainty, we believe that we have meritorious defenses to all of these cases
and intend to defend them vigorously.

<PAGE>   51
 
     We currently and from time to time are involved in other litigation
incidental to the conduct of our business. The damages claimed against us in
some of these litigations are substantial. Although the amount of liability that
may result from these matters cannot be ascertained, we do not currently believe
that, in the aggregate, they will result in liabilities material to our
consolidated financial condition, results of operations or cash flow.

Pursuant to his employment agreement, we paid Mr. Jenkins an annual base salary
of $525,000 for 1997 and a bonus of $577,500. In 1998, Mr. Jenkins' employment
agreement was amended to increase his annual base salary to $600,000 and to
provide the Board of Directors greater discretion in determining the measures of
our operating results upon which Mr. Jenkins' annual bonus will be based. Mr.
Jenkins' employment agreement does not contain a stated termination date, but
rather is terminable at will by us or Mr. Jenkins. Mr. Jenkins' employment
agreement provides that if he is terminated without cause or if he terminates
his employment for Good Reason (as defined in his employment agreement and which
includes a change of control in the Company), he will continue to receive his
base salary and performance bonus for a period of two years from his
termination.
 
     Pursuant to his employment agreement, we paid Mr. Bazlen an annual base
salary of $400,000 and a bonus of $440,000 for 1997. In 1998, Mr. Bazlen's
employment agreement was amended to increase his annual base salary to $450,000
and to provide the board of directors greater discretion in determining the
measures of our operating results upon which Mr. Bazlen's annual bonus will be
based. Mr. Bazlen's employment agreement does not contain a stated termination
date, but rather is terminable at will by the Company or Mr. Bazlen. Mr.
Bazlen's employment agreement provides that if we were to terminate the
employment of Mr. Bazlen without cause or if he terminates his employment for
Good Reason (as defined in his employment agreement), he will continue to
receive his annual base salary then in effect for a period of one year from his
termination.
 
  OTHER PAYMENTS
 
     In connection with Mr. Jenkins becoming our Chief Executive Officer, we
made the following additional payments to him:
 
     - a cash bonus for future services of $1,000,000, which he used to purchase
       shares of our common stock from the Investcorp Group (subject to vesting
       restrictions expiring in full in 1999);
 
     - a loan in the amount of $441,500, used to pay the state and federal
       income taxes he incurred in connection with receipt of the cash bonus;
       and
 
   
     - a loan in the amount of $550,000 used for the costs of relocating to, and
       purchasing a home in, the Phoenix area. See "Certain Relationships and
       Related Transactions."
    
 
     The Investcorp Group and the Company have agreed to accelerate the vesting
of the shares purchased by Mr. Jenkins from the Investcorp Group to permit their
sale in this offering. The loan for $441,500 will be repaid by Mr. Jenkins with
the proceeds he receives from the sale of these shares in this offering.

  OPTION GRANTS
 
     In connection with Mr. Jenkins becoming the Company's Chief Executive
Officer, Mr. Jenkins received an option to purchase 401,967 shares of our common
stock, exercisable at $12.04 per share. In April 1998, this option vested to the
extent of 100,491 shares. As a result of vesting acceleration triggered by our
IPO, the remainder of this option will generally vest and become exercisable on
March 17, 2000, subject to earlier vesting based upon the achievement of certain
EBITDA targets and the occurrence of other specified events.
 
     In connection with the Trak West Acquisition, we granted Mr. Jenkins an
option to purchase 39,940 shares of our common stock, exercisable at $12.04 per
share. This option will vest and become exercisable in four equal annual
installments beginning in April 1999.
 
     In connection with our IPO, we granted Mr. Jenkins an option to purchase
216,634 shares of our common stock, exercisable at $20.00 per share. This option
will vest and become exercisable in three equal annual installments beginning in
April 2000.
 
     In connection with the execution of his employment agreement, we granted
Mr. Bazlen an option to purchase 299,337 shares of our common stock, exercisable
at $12.04 per share. This option has both vested and become exercisable to the
extent of 106,905 shares. As a result of vesting acceleration triggered by our
IPO, the remainder of this option will generally vest and become exercisable on
March 17, 2000, subject to earlier vesting based upon the achievement of certain
EBITDA targets and the occurrence of other specified events.
 
RETIREMENT PROGRAM
 
     We sponsor the CSK Auto, Inc. Retirement Program, a defined contribution
plan that is qualified under Section 401(k) of the Internal Revenue Code of
1986, as amended (the "Code"). Participation in the retirement program is
voluntary and available to any employee who is 21 years of age and who has
worked for us for more than one year. Each participant can elect to contribute
up to 15% of his compensation on a pre-tax basis, subject to the legal maximum
of $9,500. In accordance with the provisions of the retirement program, we may
elect to make matching contributions to the retirement program. For calendar
year 1996, we matched 20% of the first 6% of compensation contributed by each
participant for the year. Contributions to the retirement program and retirement
program earnings are fully vested. We made matching contributions of
approximately $288,000 to the retirement program in fiscal 1996.
 
     Effective October 1, 1997, we changed our matching formula under the
retirement program. We now match the first 4% of annual compensation contributed
as follows:

EQUITY PARTICIPATION AGREEMENTS
 
   
     Prior to the 1996 Recapitalization, we entered into incentive compensation
agreements with certain of our executives. Pursuant to the agreements, Messrs.
Bazlen, Fraser, Watson and Shortt, as well as three former executive officers,
became entitled to certain payments in connection with the 1996 Recapitalization
based upon the consideration they would have been entitled to if they had owned
an aggregate of 6.4% of our common stock and had sold all of such common stock
in the 1996 Recapitalization. In satisfaction of our obligations under these
agreements, these individuals received payments on the closing of the
Acquisition 1996 Recapitalization in October 1996 and in November 1997 in the
following amounts: Mr. Bazlen: $6.5 million and $6.7 million; Mr. Fraser: $0.3
million and $0.3 million; Mr. Watson: $0.1 million and $0.1 million; and Mr.
Shortt: $0.07 million and $0.07 million. Carmel reimbursed the Company for 60%
(the estimated after-tax cost to the Company) of the amount of the payments made
in November 1997.
    
 
STOCK OPTION PLANS
 
     We have adopted a number of stock-based incentive plans to reward our
associates, executive officers and non-employee directors. The primary
objectives of these plans are to attract and retain the services of qualified
and talented employees, executives and non-employee directors who can contribute
materially to our success and profitability. As the following descriptions are
summaries of the actual plans, they omit certain details which are not material
to a general understanding of the plans. Copies of the complete plans are filed
as exhibits to the registration statement of which this prospectus is a part.
 
  THE 1996 ASSOCIATE STOCK OPTION PLAN
 
   
     Store associates, store managers and salaried corporate and warehouse
employees are eligible to participate in this plan (the "Associate Plan"). We
may grant options to purchase up to an aggregate of 1,026,300 shares of common
stock under the Associate Plan. As of November 1, 1998, we have granted options
to purchase 773,039 shares under the Associate Plan, with exercise prices
ranging from of $12.04 to $27.69 per share.
    
 
     Options granted under the Associate Plan vest and become exerciseable in
three equal installments on the second, third and fourth anniversaries of the
date of their grant, assuming the associate's employment continues during this
period ("Four Year Vesting"). All options granted under the Associate Plan
expire on the seventh anniversary of the date of grant (or, under certain
circumstances, 30 days later). In the event that an optionee's employment is
terminated, depending on the reasons for such termination, the option may
terminate, or remain exercisable for a short period. In the event of a sale of
more than 80% of the outstanding shares of our capital stock, the unvested
portion of any option automatically vests.
 
  THE 1996 EXECUTIVE STOCK OPTION PLAN
 
   
     Vice Presidents and Senior Vice Presidents are eligible to participate in
this plan (the "Executive Plan"). We may grant options to purchase up to an
aggregate of 684,200 shares of common stock under the Executive Plan. As of
November 1, 1998, we have granted options to
    
 
                                       59
<PAGE>   61
 
purchase 380,923 shares under the Executive Plan, with exercise prices ranging
from $12.04 to $25.50 per share.
 
     Options granted under the Executive Plan will be subject to the Four Year
Vesting as to 84% of such options and performance vesting (over the same four
years) as to the remaining 16%. The performance vesting criteria will be based
upon achieving specified operating results. Partial vesting of options subject
to performance vesting will occur if we achieve less than 95% of the specified
operating results. Any portion of options granted under the Executive Plan which
are subject to performance vesting and which do not vest during the four years
will automatically vest 90 days prior to the end of the option's term. If the
specified operating results are exceeded for any year by at least 10%, the
executive will receive options for up to an additional 5% (20% on a cumulative
basis) of his or her original option grant. All options granted under the
Executive Plan expire on the seventh anniversary of the date of grant (or, under
certain circumstances, 30 days later). In the event that an optionee's
employment is terminated, depending on the reasons for such termination, the
option may terminate, or remain exercisable for a short period. In the event of
a sale of more than 80% of the outstanding shares of our capital stock, the
unvested portion of any option automatically vests.
 
  THE DIRECTORS STOCK PLAN
 
   
     Our board of directors adopted this plan (the "Directors Plan") on June 12,
1998, but it will not become effective unless it is approved by our stockholders
at our next annual meeting. All of our non-employee directors will be eligible
to participate in the Directors Plan, but directors affiliated with the
Investcorp Group or the Carmel Group will not initially participate. Assuming
that our stockholders approve the Directors Plan, we will be able to make
stock-based awards of up to an aggregate of 50,000 shares. These awards may be
in the form of restricted stock grants or stock options. As of November 1, 1998,
we have granted 1,498 restricted shares under the Directors Plan, but these
grants are also subject to the approval of our stockholders at our next annual
meeting.
    
 
  GENERAL
 
   
     Each of the Associate Plan, the Executive Plan and the Directors Plan
(collectively, the "Plans") may be administered by a committee of the board of
directors which would have broad authority in administering and interpreting the
Plans, or, if a committee has not been appointed, by the entire board of
directors. The Associate and Executive Plans provide that the committee must
consist entirely of "Non-Employee Directors" (as defined in Rule 16b-3 under the
Securities Exchange Act of 1934, as amended). A committee has not yet been
appointed to administer any of the Plans.
    
 
     Options granted under the Plans may be options intended to qualify as
incentive stock options under Section 422 of the Internal Revenue Code of 1986,
as amended, or options not intended to so qualify.

MANAGEMENT STOCK PURCHASE AGREEMENTS AND 1997 STOCK LOAN PLAN
 
   
     In 1997, we established stock purchase and stock loan programs. Under these
plans, members of our senior management purchased an aggregate of 180,600 shares
of our common stock at $12.04 per share, the price per share paid by the
Investcorp Group for the shares it purchased in the 1996 Recapitalization, and
received loans from us to pay for a portion of these purchases. If a participant
used more borrowed money than cash to purchase his shares, he will have to
reduce the principal balance of the loan using 50% of the after-tax portion of
his annual bonus until it equals the amount of cash he used to purchase shares,
if any. Each loan participant entered into an agreement pledging his shares and
executed a secured promissory note. These notes mature in six years, and bear
interest at the same rate as the revolving credit portion of the Senior Credit
Facility. In addition, we loaned funds to employees who purchased shares under
the stock purchase program to pay any income taxes associated with such
purchases. For each share of our common stock purchased by a participant under
the stock purchase program for cash, such participant received an option under
the Executive Plan to purchase one share of our common stock.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
TRANSACTIONS WITH RELATED PARTIES
 
   
     From time to time we have entered into real property leases with related
parties.
    
 
   
     - In October 1989, we entered into a nine year lease (the "Initial Lease")
       for our corporate headquarters in Phoenix, Arizona, with an unaffiliated
       landlord. During January 1994, Missouri Falls Holdings Corp., an
       affiliate of Carmel, acquired an interest in the partnership ("Missouri
       Falls Partners") which acquired the building and assumed the lease
       between us and the former landlord. In connection with the 1996
       Recapitalization we extended the Initial Lease through October 2006. The
       lease relates to approximately 78,577 square feet and provides for a
       current base rent of approximately $1,490,000 per year.
    
 
     - In April 1995, we assumed a lease (the "Subsequent Lease") between a
       former tenant and Missouri Falls Partners for approximately 11,683 square
       feet of additional office space at our corporate headquarters. In
       connection with the 1996 Recapitalization, we extended the Subsequent
       Lease through October 2006. At its originally scheduled termination as of
       April 1998, rent under the Subsequent Lease increased to the same per
       square foot rent as is charged under the Initial Lease.
 
     - We lease approximately 5,754 square feet of additional space at the above
       premises for an annual rental of $106,449 under two separate lease
       documents with expiration dates of February 2000 and March 2000.
 
   
     - We also lease from MFP Holdings, LLC, an affiliate of Carmel, a parking
       lot adjacent to our corporate headquarters for an annual rental of
       $62,506 under a separate lease which expires in October 2006.
    
 
     From time to time, we have entered into sale-leaseback or other financing
arrangements with related parties.
 
   
     - Beginning in October 1995, we entered into a series of sale-leaseback
       transactions with Transatlantic Realty, Inc. ("Realty"), another
       affiliate of Carmel, for various real property and fixtures. The total
       funding provided by Realty in these transactions through August 2, 1998
       was approximately $33.1 million (of which $27.3 million was for real
       property and $5.8 million was for fixtures). This amount represented our
       cost of such assets. We have replaced approximately $27.3 million of the
       real property sale-leasebacks and $4.6 million of the fixture
       sale-leasebacks with similar arrangements with unrelated third parties.
       The terms of the leases with unrelated third parties were set in
       arm's-length negotiations and generally are not as favorable to us as the
       original sale-leasebacks entered into with Realty. As of November 1,
       1998, there were approximately $1.1 million of fixture sale-leasebacks
       remaining in this facility. We intend to continue to replace such sale-
       leasebacks and have agreed to use our best efforts to do so (including,
       in certain cases, increasing the rent payable under such leases).
    
 
   
     - Beginning in October 1996, we have entered into a series of
       sale-leaseback transactions with Transatlantic Leasing, Inc. ("Leasing"),
       another affiliate of Carmel, for certain real
    
                                       62
<PAGE>   64
 
   
       property. The terms of the leases under the facility with Leasing were
       set in arm's-length negotiations. As of November 1, 1998, the net funding
       provided by Leasing in these transactions was approximately $2.6 million.
       In October 1997, we established a new sale-leaseback facility and we
       terminated the facility with Leasing. See "Management's Discussion and
       Analysis of Financial Condition and Results of Operations -- Liquidity
       and Capital Resources" and note 4 to our consolidated financial
       statements.
    
 
   
     - We incurred an obligation in connection with the purchase of product from
       two of our vendors. In fiscal 1996, this obligation was acquired by
       Transatlantic Finance, Ltd. ("Transatlantic"), an affiliate of Carmel and
       a member of the Carmel Group. At that time, we owed approximately $16.5
       million (less anticipated discounts of approximately $0.8 million) to the
       vendors. As of September 29, 1996, the obligation has been paid in full.
    
 
     - As of December 27, 1996, we paid Transatlantic approximately $15.5
       million pursuant to a promissory note dated July 24, 1996. The promissory
       note was issued to evidence a loan to the Company, in the amount of $15.0
       million, the proceeds of which were used for the payment of vendors.
 
     - In connection with the 1996 Recapitalization, we issued and sold $50
       million of 12% subordinated notes to the following two related parties:
 
        - Southwest Finance Limited ("Southwest Finance"), a company in which an
          affiliate of Investcorp held a minority interest. Southwest Finance
          acquired $40.0 million of 12% subordinated notes and received a fee of
          $4.0 million.
 
        - Transatlantic acquired $10.0 million of the 12% subordinated notes.
 
    We used $50.5 million of the net proceeds of our IPO to redeem the 12%
    subordinated notes, including a redemption premium of $0.5 million.
 
     - In March 1998, we paid Transatlantic $1.0 million in fees for past
       financings.
 
     From time to time, we have paid fees to related parties for financing,
management consulting, commitment and equity placement services.
 
     - In connection with the 1996 Recapitalization, we paid Invifin S.A., an
       affiliate of Investcorp ("Invifin"), a fee of $1.575 million for
       providing a standby commitment to fund the amount of the Senior Credit
       Facility. We also paid Investcorp International Inc. ("International")
       advisory fees of $1.275 million and $3.15 million for arranging the
       Senior Credit Facility.
 
   
     - In connection with the 1996 Recapitalization, we entered into a five-year
       agreement for management advisory and consulting services with
       International. The Company paid International $5.0 million in advance for
       the entire term of the management agreement. In accordance with its
       terms, the management agreement terminated after our IPO.
    
 
     We believe that the terms of the transactions with affiliated parties
described above in this section were no less favorable to us than terms that may
have been available from independent third parties at the time of the applicable
transaction.

     - In connection with the Trak West Acquisition in December 1997, South Bay
       Limited, a member of the Investcorp Group ("South Bay"), and
       Transatlantic, purchased additional stock of the Company for
       approximately $11.2 million and $10.8 million, respectively. After giving
       effect to such purchases, the Investcorp Group, having sold a portion of
       its common equity interest to Mr. Jenkins at its cost pursuant to a prior
       agreement, owned a 50.1% common equity interest in the Company and the
       Carmel Group, having sold a portion of its common equity to a different
       member of management of the Company at its cost pursuant to a prior
       agreement, owned a 47.1% common equity interest in the Company. In
       connection with the sale of capital stock to the Investcorp Group, an
       affiliate of Investcorp was paid a $1.0 million placement fee. In
       connection with the negotiation of the Trak West Acquisition, TG
       Investments, Ltd., an affiliate of Carmel, was paid a $1.0 million
       consulting fee.
 
     In connection with his engagement as Chief Executive Officer, we lent Mr.
Jenkins $550,000, which he used to finance the purchase of the new home required
as a result of his relocation. This loan matures in 1999 and bears interest at a
rate of 4.535%. This loan was authorized by the Board of Directors prior to the
commencement of Mr. Jenkins' employment. We also lent Mr. Jenkins $441,500 to
pay the state and federal income taxes he incurred in connection with the
$1,000,000 cash bonus that he used to purchase shares of common stock from a
member of the Investcorp Group. This loan has a three year term, is secured by a
pledge of 83,078 shares of common stock and bears interest at the same rate
applicable to borrowings under the revolving credit portion of the Senior Credit
Facility. This loan will be repaid by Mr. Jenkins with a portion of his proceeds
from this offering.
 
STOCKHOLDERS' AGREEMENT
 
   
     At the time of the 1996 Recapitalization, each of our stockholders at the
time (the "Agreeing Stockholders"), the Company and CSK Auto, Inc. entered into
a stockholders' agreement which restricts the transfer of shares of common stock
held by those stockholders. The stockholders' agreement also entitles the
Agreeing Stockholders to certain rights regarding the transfer of their shares
and corporate governance. Any party who purchased Shares from the Agreeing
Stockholders became party to the stockholders' agreement as well. In addition,
in December 1997, upon the purchase of newly issued common stock, Transatlantic
and South Bay, and their subsequent tranferees, became party to the
stockholders' agreement.
    
 
  TRANSFER RESTRICTIONS
 
   
     When any Agreeing Stockholder desires to sell its shares, the stockholders
agreement provides that we and each of the other Agreeing Stockholders have a
"right of first refusal" on those shares. Any proposed sales or other transfers
of shares by any Agreeing Stockholder will be subject to the first right of the
Company and each of the other Agreeing Stockholders to purchase such offered
Shares on the same terms and conditions as the proposed third-party sale, except
for (1) transfers to affiliates and certain family members ("Permitted
Transferees"), or (2) pursuant to a registered public offering (such as this
offering) or (3) pursuant to Rule 144 under the Securities Act. Any Agreeing
Stockholder wishing to sell any of its shares, whether or not it has received a
third-party offer, may offer to sell those shares to us and the other Agreeing
    
 
                                       64
<PAGE>   66
 
Stockholders on terms and conditions established by the selling Agreeing
Stockholder. In the event that we and/or the other Agreeing Stockholders do not
purchase the shares, the selling Agreeing Stockholder may sell the shares to
third parties on terms and conditions specified in the stockholders' agreement.
 
   
     The stockholders' agreement also provides the Original Investcorp Group and
the Original Carmel Group (each as defined below) with "Drag-Along" rights. If
members of the Original Investcorp Group or the Original Carmel Group were to
desire to sell all of their Shares to an unaffiliated third-party who has
offered to acquire all of our outstanding shares, then the selling Agreeing
Stockholders would have the right to require each of the other Agreeing
Stockholders to sell all of their Shares in the same transaction and upon the
same terms and conditions; provided that the other Agreeing Stockholders would
have the right to purchase, and/or have us purchase, from the selling Agreeing
Stockholders all of the shares held by the selling Agreeing Stockholders upon
the terms and conditions of the third-party offer. For purposes of this
prospectus, the "Original Investcorp Group" shall mean the members of the
Investcorp Group (except South Bay and its transferees) and each of their
Permitted Transferees; the "Original Carmel Group" shall mean Carmel and each of
its Permitted Transferees; the "Investcorp Group" shall mean the members of the
Investcorp Group and each of their respective transferees and subsequent
transferees; and the "Carmel Group" shall mean Carmel, Transatlantic and each of
their transferees and subsequent transferees.
    
 
     The stockholders' agreement also provides Agreeing Stockholders with
"Tag-Along Rights." If any Agreeing Stockholder (the "Proposed Transferor")
proposed to transfer any Shares (other than to Permitted Transferees, or
pursuant to a registered public offering or under Rule 144) to any person (the
"Proposed Purchaser"), each of the other Agreeing Stockholders would have the
right to require the Proposed Purchaser to purchase a pro rata portion of its
shares, and the Proposed Transferor would have to make a corresponding reduction
in the number of its Shares to be purchased. Each Agreeing Stockholder also has
preemptive rights under certain circumstances to acquire a portion of any
additional Shares we offer at any time, other than in connection with a public
offering and certain non-cash issuances, in order to enable such Agreeing
Stockholder to maintain its percentage equity ownership.
 
   
     The stockholders' agreement also contains "Buy-Sell" provisions. Members of
the Investcorp Group or the Carmel Group have the right to offer all of their
shares for sale to the other Agreeing Stockholders who are members of the other
group at a price established by the offering Agreeing Stockholders. If the
Company and/or the offeree Agreeing Stockholders do not purchase the offered
shares, the offering Agreeing Stockholders must then purchase all of the shares
held by the members of the other group at the price first offered by the
offering Agreeing Stockholders.
    
 
     Pursuant to the stockholders' agreement, the Agreeing Stockholders have
demand registration rights ("Demand Rights") and piggy-back registration rights
("Piggy-back Rights"). The Demand Rights entitle the Agreeing Stockholders to
require us to register all or any of the unregistered shares held by the
exercising Agreeing Stockholders. The Investcorp Group as a whole may exercise
Demand Rights up to four times. The Carmel Group as a whole may also exercise
Demand Rights up to four times. The Piggy-back Rights entitle the Agreeing

Stockholders, at any time that we propose to sell any equity securities in a
transaction registered under the Securities Act, to include a portion of their
unregistered stock in such offering. This offering is being made pursuant to an
exercise of these Demand Rights.
 
   
     The stockholder's agreement provides that the Agreeing Stockholders will
agree to restrictions on their ability to sell or otherwise transfer their
shares for 90 days following certain registered public offerings by the Company.
    
 
  CORPORATE GOVERNANCE
 
   
     The stockholders' agreement provides that the Investcorp Group will have
the right to nominate a majority of the members of our boards of directors of
the Company, CSK Auto, Inc. and their respective subsidiaries so long as it
holds a greater number of shares than the Carmel Group, and the Carmel Group
will have the right to nominate a majority of the members of such boards of
directors during any period in which the Carmel Group holds a greater number of
shares. Pursuant to the stockholders' agreement, each of the Agreeing
Stockholders agrees to vote all of its shares in favor of each of the persons
nominated to such boards by each group.
    
 
   
     In addition, at least one member of the boards of directors nominated by
each group must approve certain fundamental corporate actions and significant
transactions proposed to be taken by us or CSK Auto, Inc. These provisions
terminate after either (1) the Investcorp Group and the Carmel Group hold in the
aggregate Shares representing less than 50% of the outstanding shares of common
stock or (2) either the Original Investcorp Group or the Original Carmel Group
holds less than 50% of the number of shares held by such group immediately after
the 1996 Recapitalization. After this offering, these provisions will terminate.
    
 
     The rest of the stockholders' agreement, other than the registration rights
provisions, will terminate after either the Investcorp Group or the Carmel Group
holds less than the lesser of (1) 5% of the then current voting power or (2) 10%
of the voting power held by such group at the time of the 1996 Recapitalization.

 (1) Prior to this offering the Investcorp Group, as defined in the
     stockholders' agreement, owned 9,655,715 shares, or 34.8%, of the
     outstanding shares of common stock and will own 6,030,964 shares, or 21.7%
     after this offering. Also prior to this offering the Carmel Group, as
     defined in the stockholders' agreement, owns 9,277,073 shares, or 33.4%, of
     the outstanding shares of common stock and will own 5,901,824 shares, or
     21.3%, after this offering. As the parties to the stockholders' agreement
     have agreed to vote with respect to certain matters as set forth therein,
     all of them may be deemed to be a control group. As a result, each
     stockholder may be deemed to beneficially own all shares of common stock
     owned by all of the parties to the stockholders' agreement. The number of
     shares shown as owned by the Investcorp Group does not include any shares
     which Maynard Jenkins has the right to acquire upon exercise of options,
     and the number of shares shown as owned by the Carmel Group does not
     include any shares which James Bazlen has the right to acquire upon
     exercise of options (see note (9) below). See "Certain Relationships and
     Related Transactions -- Stockholders' Agreement." Because we believe that
     our presentation more accurately reflects ownership of the Company's
     capital stock, this table does not reflect shares which may be deemed to be
     beneficially owned by any entity solely by virtue of the stockholders'
     agreement.

     Investcorp CSK Holdings L.P., a Cayman Islands Limited Partnership in which
     Investcorp both owns a majority economic ownership interest and is the sole
     general partner. The number of shares of common stock shown as beneficially
     owned by Investcorp prior to the offering includes 247,110 shares of
     outstanding common stock that Investcorp CSK Holdings L.P. has the right,
     pursuant to an option, to acquire from other stockholders of the Company.
     The number of shares of common stock shown as being offered by Investcorp
     includes 91,425 of such option shares, and the number of shares of common
     stock shown as beneficially owned by Investcorp after the offering includes

     certain "protectors" who must authorize any action taken by the trustee and
     who have the authority to discharge the trustee and to appoint substitute
     trustees. These protectors are Saul Tobias Bernstein, Gerrit Van Riemsdijk
     and Robert Smith (who is also a director of the Company). These individuals
     are not otherwise associated with us or Carmel. The Carmel Agreement
     provides that Carmel shall continue until 21 years after the death of the
     last survivor of the descendants of certain persons living on the date it
     was established (the "Carmel Term"). Certain members of the families of
     Jules Trump (a director of the Company) and Eddie Trump (a director of the
     Company) may under limited circumstances appoint beneficiaries or
     themselves become beneficiaries (by appointment or at the end of the Carmel
     Term without appointment). If there are no such beneficiaries at the end of
     the Carmel Term, the assets of Carmel will be paid out to certain
     charitable institutions. The number of shares shown as owned by Carmel

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     As of November 1, 1998, we had 50,000,000 authorized shares of common
stock, $.01 par value per share, of which 27,742,022 shares are issued and
outstanding. The material terms of our certificate of incorporation and bylaws
are discussed below.
 
COMMON STOCK
 
     Our stockholders are entitled to one vote per share in the election of
directors and on all other matters on which stockholders are entitled or
permitted to vote. Our stockholders are not entitled to vote cumulatively for
the election of directors. Except as set forth in the stockholders' agreement,
our stockholders have no redemption, conversion, preemptive or other
subscription rights. There are no sinking fund provisions relating the common
stock. In the event of the liquidation, dissolution or winding up of the
Company, our stockholders are entitled to share ratably in all of our assets of,
if any, remaining after satisfaction of our debts and liabilities. The
outstanding shares of common stock are validly issued, fully paid and
nonassessable.
 
     Our stockholders are entitled to receive dividends when and as declared by
our board of directors out of funds legally available therefor. We do not
anticipate paying cash dividends on the common stock in the foreseeable future.
See "Price Range of Common Stock and Dividend Policy."
 
CERTAIN PROVISIONS OF DELAWARE LAW
 
     The Company is incorporated under the Delaware General Corporation Law (the
"DGCL"). Section 203 of the DGCL restricts certain transactions and "business
combinations" between a company and an "interested stockholder" (in general, a
stockholder owning 15% or more of a company's outstanding voting stock) or an
affiliate or associate of an interested stockholder, for a period of three years
from the date the stockholder becomes an interested stockholder. A "business
combination" includes mergers, asset sales and other transactions resulting in a
financial benefit to the interested stockholder. Subject to certain exceptions,
unless the transaction is approved by the board of directors and the holders of
at least 66 2/3% of the outstanding voting stock of a company (excluding shares
held by the interested stockholder), Section 203 prohibits significant business
transactions such as a merger with, disposition of assets to, or receipt of
disproportionate financial benefits by, the interested stockholder, or any other
transaction that would increase the interested stockholder's proportionate
ownership of any class or series of a company's stock. The statutory ban does
not apply if, upon consummation of the transaction in which any person becomes
an interested stockholder, the interested stockholder owns at least 85% of the
outstanding voting stock of a company (excluding shares held by persons who are
both directors and officers or by certain employee stock plans).
 
     Our certificate of incorporation contains certain provisions permitted
under the DGCL relating to the liability of directors. The certificate of
incorporation provides that, to the fullest extent permitted by the DGCL, no
director will be liable to us or any of our stockholders for monetary damages
for breach of fiduciary duty as a director. Our certificate of incorporation and
 
                                       70
<PAGE>   72
 
bylaws also contain provisions indemnifying the directors and officers to the
fullest extent permitted by the DGCL.
 
   
     Section 203 and the provisions of our certificate of incorporation and
bylaws described above may make it more difficult for a third party to acquire,
or discourage acquisition bids for, the Company. Section 203 and these
provisions could have the effect of inhibiting attempts to change the membership
of the board of directors. In addition, the limited liability provisions in our
certificate of incorporation and the indemnification provisions in both the
certificate of incorporation and bylaws, may discourage stockholders from
bringing a lawsuit against directors for breach of their fiduciary duty
(including breaches resulting from grossly negligent conduct) and may have the
effect of reducing the likelihood of derivative litigation against directors and
officers, even though such an action, if successful, might otherwise have
benefited us and our stockholders. Furthermore, a stockholder's investment in
the Company may be adversely affected to the extent we pay the costs of
settlement and damage awards against our directors and officers pursuant to the
indemnification provisions in our bylaws. The limited liability provisions in
our certificate of Incorporation will not limit the liability of the Company's
directors under federal securities laws.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
     CSK Auto, Inc., our primary subsidiary, has two significant items of
indebtedness: its "Senior Credit Facility," and its "11% Senior Subordinated
Notes." The material terms of these debt obligations are described below. As a
summary, the following discussion necessarily omits many of the details of these
arrangements. For a full and complete understanding of these obligations, we
strongly urge investors to read the specific provisions of these agreements and
instruments. Copies of these documents have been filed as exhibits to the
Registration Statement of which this prospectus is a part.
 
SENIOR CREDIT FACILITY
 
     On December 8, 1997, CSK Auto, Inc. entered into the Amended and Restated
Credit Agreement (the "Senior Credit Facility") with several lenders, with The
Chase Manhattan Bank acting as the administrative agent. This $300.0 million
facility provides for a term loan in the aggregate amount of $175.0 million, and
a revolving credit facility in the amount of $125.0 million. We have guaranteed
these obligations. The Senior Credit Facility will be similarly guaranteed by
any future United States subsidiaries of CSK Auto, Inc.
 
     To secure the obligations under the Senior Credit Facility, CSK Auto, Inc.
has granted a first priority security interest in substantially all of its
personal property. Similarly, we have pledged the issued and outstanding capital
stock of CSK Auto, Inc. CSK Auto, Inc. will also pledge the issued and
outstanding capital stock of any future United States subsidiaries.
 
  TERM LOAN
 
     As of August 2, 1998, $146.6 million was outstanding under the term loan,
which matures on October 31, 2003, with aggregate annual principal installments
scheduled as follows:

  REVOLVING CREDIT FACILITY
 
     As of August 2, 1998, $41.0 million was outstanding under the revolving
credit facility, which matures on October 31, 2001. CSK Auto, Inc. is entitled
to draw amounts under the revolving credit facility to use for general corporate
purposes, including:
 
   
     - The redemption, repayment or repurchase of up to $20.0 million aggregate
       principal amount of the 11% Senior Subordinated Notes;
    
 
   
     - Acquisitions of companies engaged in similar businesses, in an aggregate
       amount of $50.0 million, subject to pro forma compliance with financial
       covenants; and
    
 
                                       72
<PAGE>   74
 
   
     - Investments in the development of new or relocated stores in an aggregate
       amount not to exceed at any one time $50.0 million.
    
 
     The 11% Senior Subordinated Notes limit the amount CSK Auto, Inc. can draw
on the revolving credit facility. See "-- 11% Senior Subordinated Notes Due
2006 -- Certain Covenants."
 
  INTEREST RATES AND FEES
 
     The loans under the Senior Credit Facility accrue interest at a variable
rate. As of November 1, 1998, this rate was 6.75% for the term loan, and
approximately 6.90% for loans under the revolving credit facility. The
applicable interest rate is set at a specified margin above one of two agreed
upon fluctuating benchmark rates which we may elect from time to time. The first
benchmark rate is the highest of the federal funds rate plus 0.5%, the secondary
rate for 3-month certificates of deposit plus 1%, or The Chase Manhattan Bank's
prime rate. The second benchmark rate is an adjusted eurodollar rate. The
interest rate margins are subject to quarterly adjustment based upon the ratio
of CSK Auto, Inc.'s "consolidated funded indebtedness" at the end of a fiscal
quarter to its "consolidated EBITDA" for the four preceding fiscal quarters (as
such terms are defined in the Senior Credit Facility loan documents).
 
     CSK Auto, Inc. is required to pay to the lenders an annual commitment fee
equal to .375% of the average daily amount of the available revolving credit
commitment. The commitment fee is also subject to period adjustment in the same
manner as are the interest rate margins. CSK Auto, Inc. is also required to pay
to The Chase Manhattan Bank an annual agent's fee of $100,000.
 
  MANDATORY AND OPTIONAL PREPAYMENTS
 
     The Senior Credit Facility must be prepaid as follows:
 
          - 50% of the net proceeds of any sale of voting stock to anyone
            other than a current stockholder or their affiliates, must be
            applied toward the prepayment of the term loan.
 
          - 100% of the net proceeds of certain asset sales and exchanges,
            and the incurrence of any additional indebtedness (other than
            indebtedness permitted under the Senior Credit Facility) must
            be applied first to the prepayment of the term loan and then to
            permanently reduce the revolving credit commitments.
 
          - 50% of CSK Auto, Inc.'s excess cash flow (as defined in the
            Senior Credit Facility) must be applied toward the prepayment
            of the term loan.
 
     Subject to certain conditions, CSK Auto, Inc. may, from time to time, make
optional prepayments of the Senior Credit Facility obligations without premium
or penalty.
 
  CERTAIN COVENANTS; EVENTS OF DEFAULT
 
     The Senior Credit Facility imposes standard affirmative and negative
covenants and financial tests, and specifies customary events of default. In
addition, a "change of control" allows the
 
                                       73
<PAGE>   75
 
lenders to accelerate the loans. A change of control occurs whenever anyone
acquires the power to vote at least 30% of the common stock, on a fully diluted
basis, and holds a greater percentage of shares of common stock than the
Investcorp Group. A change of control also occurs if a majority of the board of
directors ceases to be composed of Investcorp Group nominees. This offering will
not result in a change of control under the Senior Credit Facility.
 
11% SENIOR SUBORDINATED NOTES DUE 2006
 
     On October 30, 1996, CSK Auto, Inc. issued and sold in a private placement
$125.0 million aggregate principal amount of 11% Senior Subordinated Notes due
2006 under an indenture between CSK Auto, Inc. and The Bank of New York (as
successor to Wells Fargo Bank, N.A.), as trustee. On June 18, 1997, all of these
notes were exchanged for a like principal amount of CSK Auto, Inc.'s 11% Series
A Senior Subordinated Notes due 2006 (the "11% Senior Subordinated Notes") a
transaction registered under the Securities Act. In March 1997, we used the
proceeds of our IPO to prepay approximately $43.8 million of these notes.
 
   
     The 11% Senior Subordinated Notes bear interest at 11% per year, payable
semiannually in arrears on each May 1 and November 1, and mature on November 1,
2006. These notes are general, unsecured senior subordinated obligations of CSK
Auto, Inc. and will be guaranteed by any of its future United States
subsidiaries.
    
 
  MANDATORY AND OPTIONAL REDEMPTION
 
     On and after November 1, 2001, the 11% Senior Subordinated Notes will be
redeemable, at our option, in whole or in part, at the redemption prices set
forth below (expressed in percentages of principal amount), plus accrued and
unpaid interest, if any, to the applicable redemption date:

November 1, 2004 and thereafter.............................      100.000%
</TABLE>
 
  CERTAIN COVENANTS; EVENTS OF DEFAULT
 
     The indenture contains certain standard covenants by and restrictions on
CSK Auto, Inc., as well as standard events of default. In addition, the
indenture restricts CSK Auto, Inc. from making additional borrowings under its
revolving credit facility that, when added to the aggregate amount of
outstanding borrowings under the Senior Credit Facility (including term loans),
exceed $200.0 million. This restriction does not apply if the new borrowings are
of a type specifically permitted by the indenture, or, if after giving pro forma
effect to such new borrowings the ratio of CSK Auto, Inc.'s consolidated EBITDA
to fixed charges (as such terms are defined in the indenture) exceeds 2.25 to 1.
As of August 2, 1998 this ratio was 2.79 to 1.
 
  REPURCHASE AT THE OPTION OF HOLDERS
 
     The indenture provides that upon a "change of control," each holder of 11%
Senior Subordinated Notes will have the right to require CSK Auto, Inc. to
repurchase all or any part
 
                                       74
<PAGE>   76
 
of such holder's notes at a purchase price in cash equal to 101% of the
principal amount plus accrued and unpaid interest, if any, to the date of
purchase. A "change of control" is deemed to occur if any person other than the
Investcorp Group or its affiliates, or members of senior management of the
Company or CSK Auto, Inc. acquires or obtains the right to acquire, directly or
indirectly, 35% or more of the total voting power of the Company or CSK Auto,
Inc. However, this is not a "change of control" if the Investcorp Group, or its
affiliates, or members of senior management of the Company and CSK Auto, Inc.
collectively hold at least the same percentage of total voting power as the
acquiring person and are still able to designate for election a majority of the
board members of the Company and CSK Auto, Inc. A "change of control" also will
occur if any person (other than the Investcorp Group or its affiliates, or
members of senior management of the Company and CSK Auto, Inc.) nominates, in
one or more elections, directors of the Company or CSK Auto, Inc., who are then
elected and become a majority of the board of directors of the Company or CSK
Auto, Inc., as the case may be. Because of restrictive covenants contained in
the Senior Credit Facility, we may not be able to fund this change of control
obligation without refinancing our indebtedness.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     The market price of our stock may fall as a result of sales of a large
number of shares of common stock in the market after this offering or the
perception that such sales could occur.
 
   
     There are 27,742,022 shares of common stock outstanding. All of the shares
sold in this offering, the 8,625,000 shares sold in our IPO and 3,634 shares
issued pursuant to the exercise of options under our stock option plans will be
fully transferable without restriction or further registration under the
Securities Act, except that shares purchased by an "affiliate" of the Company
(in general, any person who has a control relationship to the Company) may be
resold only if registered under the Securities Act or if transferred pursuant to
an exemption from registration, including resales pursuant to Rule 144 under the
Securities Act ("Rule 144") and Regulation S under the Securities Act
("Regulation S"). The remaining 12,113,388 outstanding shares of common stock
are deemed to be "restricted securities" as that term is defined in Rule 144,
and are eligible for sale in the public market in compliance with Rule 144. As
each of the members of the Investcorp Group, the Carmel Group and their
respective transferees are party to the stockholders' agreement, all such
stockholders may be deemed to be affiliates of the Company and resales of common
stock by such stockholders may be subject to the volume limitations of Rule 144.
See "Certain Relationships and Related Transactions -- Stockholders' Agreement."
Subject to certain exceptions, the Company and stockholders of the Company
owning an aggregate of 11,932,788 shares have agreed that they will not offer,
sell or otherwise dispose of any of the shares of our common stock or any
securities convertible into or exercisable for our common stock, for a period of
90 days after the date of this prospectus without the prior written consent of
Donaldson, Lufkin & Jenrette Securities Corporation. At the expiration of the
90-day period described above, the holders of 11,932,788 shares of our common
stock will have contractual rights to sell such shares in a registered public
offering. See "Certain Relationships and Related Transactions -- Stockholders'
Agreement."

     The underwriting agreement provides that the obligations of the several
underwriters to purchase and accept delivery of the shares included in this
offering are subject to approval of certain legal matters by their counsel and
to certain other conditions. The underwriters are obligated to purchase and
accept delivery of all the shares (other than those shares covered by the
over-allotment option described below) if they purchase any of the shares.
 
     The underwriters initially propose to offer some of the shares directly to
the public at the public offering price set forth on the cover page of this

price less a concession not in excess of $     per share. The underwriters may
allow, and such dealers may re-allow, a concession not in excess of $     per
share on sales to certain other dealers. After the initial offering of the
shares to the public, the representatives may change the public offering price
and such concessions at any time without notice.
 
     The selling stockholders have granted to the underwriters an option,
exercisable for 30 days from the date of this prospectus, to purchase, from time
to time, in whole or in part, up to 1,050,000 additional shares at the public
offering price less the underwriting fees. The underwriters may exercise such
option solely to cover overallotments, if any, made in connection with this
offering. To the extent that the underwriters exercise such option, each
underwriter will become obligated, subject to certain conditions, to purchase a
number of additional shares approximately proportionate to such underwriter's
initial purchase commitment.
 
     The following table shows the underwriting fees to be paid to the
underwriters by the selling stockholders in connection with this offering. These

     The consolidated statements of operations, stockholders' equity (deficit)
and cash flows of the Company for the year ended January 28, 1996 were audited
by Price Waterhouse LLP. The financial statements for the years ended February
2, 1997 and February 1, 1998 were audited by Coopers & Lybrand L.L.P., which was
first engaged effective December 5, 1996. In connection with the completion of
the 1996 Recapitalization, and with the approval of the Board of Directors,
Price Waterhouse LLP was dismissed by management as the Company's independent
accountants on December 5, 1996. Price Waterhouse LLP and Coopers & Lybrand
L.L.P. subsequently merged to form PricewaterhouseCoopers LLP on July 1, 1998.

     The report of Price Waterhouse LLP with respect to the financial statements
of the Company for the fiscal year ended January 28, 1996 did not contain any
adverse opinion or disclaimer of opinion, and was not qualified or modified as
to uncertainty, audit scope or accounting principles. In connection with its
audit for the fiscal year ended January 28, 1996 and through December 5, 1996
there were no disagreements between the Company and Price Waterhouse LLP on any
matter of accounting principles or practices, financial statement disclosure or
auditing scope or procedures, which disagreements, if not resolved to the
satisfaction of Price Waterhouse LLP, would have caused it to make reference to
the subject matter thereof in connection with its report on the financial
statements for such year.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
CSK Auto Corporation
 
     We have audited the accompanying consolidated balance sheets of CSK Auto
Corporation and subsidiaries (the "Company") as of February 2, 1997 and February
1, 1998 and the related consolidated statements of operations, stockholders'
equity (deficit), and cash flows for the years then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these 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 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 CSK Auto
Corporation and subsidiaries as of February 2, 1997 and February 1, 1998 and the
consolidated results of their operations and their cash flows for the years then
ended, in conformity with generally accepted accounting principles.

states as a fully integrated company under three brand names: Checker Auto
Parts, founded in 1968 and operating in the Southwestern and Rocky Mountain
states; Schuck's Auto Supply, founded in 1917 and operating in the Pacific
Northwest; and Kragen Auto Parts, founded in 1947 and operating primarily in
California.

  PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of CSK Auto
Corporation, Auto and Auto's wholly-owned subsidiaries, Schuck's Distribution
Co. and Kragen Auto Supply Co., for all years presented. In addition, the
accounts of TRK Socal, Inc. (the former Trak West stores) are included in the

Auto.
 
  INTERIM FINANCIAL STATEMENTS
 
     The financial statements as of August 2, 1998 and for the twenty-six weeks
ended August 3, 1997 and August 2, 1998 are unaudited, and in the opinion of
management, include all adjustments (consisting only of normal recurring
adjustments) necessary for the fair presentation of results for these interim
periods. The results for the twenty-six weeks ended August 2, 1998, are not
necessarily indicative of the results to be expected for the entire fiscal year.
 
  FISCAL YEAR
 
     The Company's fiscal year end is on the Sunday nearest to January 31 of the
following calendar year. The fiscal year ended February 2, 1997 ("fiscal 1996")
consisted of 53 weeks, while the fiscal years ended February 1, 1998 ("fiscal
1997") and January 28, 1996 ("fiscal 1995") each consisted of 52 weeks.

          WEEKS ENDED AUGUST 3, 1997 AND AUGUST 2, 1998 IS UNAUDITED.)
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
  CASH EQUIVALENTS
 
     Cash equivalents consist primarily of certificates of deposit with
maturities of three months or less when purchased.
 
  ACCOUNTS RECEIVABLE
 
     Accounts receivable is primarily comprised of amounts due from vendors for
rebates or allowances and from commercial sales customers.
 
  CONCENTRATION OF CREDIT RISK
 
     Financial instruments that potentially subject the Company to concentration
of credit risk consist principally of cash and cash equivalents and trade
receivables. As of February 1, 1998, the Company had cash and cash equivalents
on deposit with a major financial institution that were in excess of FDIC
insured limits. Historically, the Company has not experienced any loss of its
cash and cash equivalents due to such concentration of credit risk.
 
     The Company does not hold collateral to secure payment of its trade
accounts receivable. However, management performs ongoing credit evaluations of
its customers' financial condition and provides an allowance for estimated
potential losses. Exposure to credit loss is limited to the carrying amount.
 
  INVENTORIES AND COST OF SALES
 
     Inventories are valued at the lower of cost or market, cost being
determined utilizing the last-in, first-out method. Cost of sales includes
product cost, net of earned vendor rebates, discounts and allowances. The
Company recognizes vendor rebates, discounts and allowances based on the terms
of the underlying agreements. Such amounts may be recognized immediately,
amortized over the life of the applicable agreements, or recognized as inventory
is sold. Certain operating and administrative costs are capitalized in
inventories. The amounts of capitalized operating and administrative costs
included in inventories as of February 2, 1997 and February 1, 1998 were
approximately $9.7 million and $11.8 million, respectively. The replacement cost
of inventories approximated $225.6 million, $316.2 million, and $314.4 million
at February 2, 1997, February 1, 1998, and August 2, 1998, respectively.
 
  PROPERTY AND EQUIPMENT
 
     Property, equipment and purchased software are recorded at cost.
Depreciation and amortization are computed for financial reporting purposes
utilizing primarily the straight-line method over the estimated useful lives of
the related assets, which range from 5 to 25 years, or

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
for leasehold improvements and property under capital lease, the base lease term
or estimated useful life, if shorter. Maintenance and repairs are charged to
earnings when incurred.
 
  STORE PREOPENING COSTS
 
     Store preopening costs, consisting primarily of incremental labor, supplies
and occupancy costs directly related to the opening of specific stores, are
capitalized as prepaid expenses and other current assets and expensed during the
month in which the store is opened.
 
  INTERNAL SOFTWARE DEVELOPMENT COSTS
 
     Internal software development costs, consisting primarily of incremental
internal labor costs and benefits, are expensed as incurred. Total amounts
charged to operations for fiscal years 1995, 1996 and 1997 were approximately
$6.2 million, $1.5 million and $1.3 million, respectively.
 
  LEASEHOLD INTERESTS
 
     Leasehold interests represent the discounted net present value of the
excess of the fair rental value over the respective contractual rent of
facilities under operating leases acquired in business combinations.
Amortization expense is computed on a straight-line basis over the respective
lease terms. Accumulated amortization totaled $16.3 million and $16.2 million at
February 2, 1997 and February 1, 1998, respectively.
 
  STORE CLOSING COSTS
 
     The Company provides an allowance for estimated costs and losses to be
incurred in connection with store closures and losses on the disposal of
store-related assets, which is net of anticipated sublease income. See Note 12.
 
  ADVERTISING
 
     The Company expenses all advertising costs as such costs are incurred.
Amounts due under vendor cooperative advertising agreements are recorded as
receivables until their collection. Advertising expense for fiscal years 1995,
1996 and 1997 totaled approximately $19.8 million, $21.8 million and $23.7
million, respectively.
 
  ASSETS HELD FOR SALE
 
     Assets held for sale consist of newly acquired land, buildings and store
fixtures owned by the Company which the Company intends in the next twelve
months to sell to and lease back from third parties under operating lease
arrangements.

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
  LONG-LIVED ASSETS
 
     The Company evaluates the carrying value of long-lived assets on a
quarterly basis to determine whether events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable and an impairment
loss should be recognized.
 
  INCOME TAXES
 
     Deferred income taxes are recognized for the tax consequences in future
years of differences between the tax basis of assets and liabilities and their
financial reporting amounts ("temporary differences") at each year end based on
enacted tax laws and statutory rates applicable to the period in which the
temporary differences are expected to affect taxable income. Valuation
allowances are established, when necessary, to reduce deferred tax assets to the
amount expected to be realized. Income tax expense includes both taxes payable
for the period and the change during the period in deferred tax assets and
liabilities.
 
  STOCK-BASED COMPENSATION
 
     Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting
for Stock-Based Compensation", encourages but does not require companies to
record compensation cost for stock-based employee compensation plans at fair
value. The Company has chosen to continue to account for stock-based
compensation using the intrinsic value method prescribed in Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" and
related interpretations thereof. Accordingly, compensation cost for stock
options is measured as the excess, if any, of the market price of the Company's
stock at the date of grant over the amount an employee must pay to acquire the
stock. See Note 9.
 
  EARNINGS PER SHARE
 
     In February 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 128, "Earnings per Share". SFAS No. 128 establishes standards for
computing and presenting earnings per share ("EPS") and supercedes Accounting
Principles Board Opinion No. 15, "Earnings per Share" ("APB 15"). SFAS No. 128
replaces the presentation of primary EPS with a presentation of basic EPS which
excludes dilution and is computed by dividing income available to common
shareholders by the weighted-average of common shares outstanding during the
period. This statement also requires dual presentation of basic EPS and diluted
EPS on the face of the income statement for all periods presented. Diluted EPS
is calculated similarly to fully diluted EPS pursuant to APB 15, with some
modifications. SFAS No. 128 is effective for financial statements issued for
periods ending after December 15, 1997, including interim periods. The Company
adopted SFAS No. 128 in fiscal 1997 and has restated all prior period EPS data
presented within these financial statements.

     Shares issuable under employee stock options are excluded from the shares
used in computing per share amounts for fiscal 1995 and 1996 and the twenty-six
weeks ended August 3, 1997 because their effect is anti-dilutive. A nominal
issuance of 8,723,550 shares of common stock occurred during fiscal 1995.
 
  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 reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.
 
  RECLASSIFICATIONS
 
     Certain prior year financial statement amounts have been reclassified to
conform to the current year presentation.
 
  NEW ACCOUNTING STANDARDS
 
     During fiscal 1997, the Company adopted SFAS No. 129, "Disclosure of
Information about Capital Structure," which had no effect on the Company's
financial position or results of

operations. During fiscal 1998, the Company adopted SFAS No. 130, "Reporting
Comprehensive Income," which had no effect on the Company's financial position
or results of operations.
 
     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information." In February 1998, the FASB issued SFAS
No. 132, "Employers Disclosures about Pensions and Other Postretirement
Benefits." The Company will adopt these statements during fiscal 1998. As these
statements only require additional disclosures in the Company's financial
statements, their adoption will not have any effect on the Company's financial
position or results of operations.
 
     In March 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants issued Statement of Position ("SOP")
98-1, "Accounting for the Cost of Computer Software Developed or Obtained for
Internal Use". The SOP defines the characteristics of internal-use computer,
software criteria for capitalization, and financial statement disclosure
requirements. The SOP is effective for fiscal years beginning after December 15,
1998, with earlier application encouraged. The Company will adopt SOP 98-1 in
fiscal 1999 and does not expect that such adoption will have a material effect
on the Company's financial position or results of operations.
 
     In April 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants issued SOP 98-5, "Reporting on the
Cost of Start-up Activities." The SOP broadly defines start-up activities as
those one-time activities related to opening a new facility, introducing a new
product or service, conducting business in a new territory, or commencing some
new operation. The SOP requires that the costs of start-up activities be
expensed as incurred and is effective for financial statements for fiscal years
beginning after December 15, 1998, with earlier application encouraged. The
Company's current accounting policy with respect to the cost of start-up
activities is to defer such costs for the approximately three month period of
time that it takes to develop a new store facility and to expense such costs
during the month that the new store opens. The Company will adopt SOP 98-5 in
fiscal 1999, which will require the Company to change its current accounting
policy to expense start-up costs as incurred. The Company does not believe that
the impact of adoption will have a material effect on the Company's financial
position or results of operations.
 
NOTE 2 -- 1996 RECAPITALIZATION
 
     In October 1996, certain affiliates of INVESTCORP S.A. ("Investcorp") and
certain other investors (collectively with Investcorp, the "Investcorp Group")
acquired a 51% common equity interest in the Company for $105.0 million in cash
from the Carmel Trust ("Carmel"), which previously had held 100% of the common
equity interests in the Company. A corporation in which an affiliate of
Investcorp held a minority interest also purchased $40.0 million in aggregate
principal amount of the Company's 12% Subordinated Notes for $40.0 million in
cash, and the

NOTE 2 -- 1996 RECAPITALIZATION, CONTINUED
Company in turn purchased $40.0 million of preferred stock of Auto.
Transatlantic Finance, Ltd., an affiliate of Carmel ("Transatlantic," and with
Carmel, the "Carmel Group") purchased $10.0 million in aggregate principal
amount of the Company's 12% Subordinated Notes, and the Company in turn
purchased $10.0 million of preferred stock of Auto. Auto then borrowed $100.0
million under the Senior Credit Facility, which together with the net proceeds
from the sale of $125.0 million of Auto's 11% Senior Subordinated Notes due 2006
and the net proceeds from the sale by Auto to the Company of $50.0 million of
preferred stock, following a dividend to the Company by Auto, was used to redeem
the stock of the Company held by Carmel for $238.5 million. Carmel then
purchased from the Company for $100.9 million a 49% common equity interest in
the Company. Auto then repaid amounts outstanding under a then existing credit
agreement, which was terminated, and paid $9.9 million to members of management
pursuant to previously existing equity participation agreements and incurred
additional expenses of $22.7 million related to the foregoing. The foregoing
transactions are referred to individually and collectively as the "1996
Recapitalization." Following the 1996 Recapitalization, the Investcorp Group
owned a 51% common equity interest in the Company, a corporation in which an
affiliate of Investcorp held a minority interest owned $40.0 million in
aggregate principal amount of the Company's 12% Subordinated Notes, Carmel owned
a 49% common equity interest in the Company, Transatlantic owned $10.0 million
in aggregate principal amount of the Company's 12% Subordinated Notes and the
Company owned 100% of the common equity and $50.0 million of preferred stock of
Auto.
 
     Prior to the 1996 Recapitalization, the Company had entered into incentive
compensation agreements with certain of its executives pursuant to which they
would be compensated in a sale of the Company's equity securities as if they
owned specified percentages of the Company's outstanding common stock. Pursuant
to these agreements, two former and five current executive officers received
certain payments in connection with the 1996 Recapitalization based upon the
consideration they would have been entitled to if they had owned an aggregate of
6.4% of the Company's common stock and had sold all of such common stock in
connection with the 1996 Recapitalization at the price per share paid for such
shares in the 1996 Recapitalization. Upon closing of the 1996 Recapitalization,
the Company became obligated to pay approximately $19.9 million under these
equity participation agreements. The Company expensed this full amount plus a
provision for estimated payroll taxes thereon during the fourth quarter of
fiscal 1996 when the 1996 Recapitalization was consummated and paid $9.9 million
(approximately 50% of the total obligation) with proceeds from the 1996
Recapitalization. The Company paid the remaining balance in November 1997 and
Carmel reimbursed the Company for approximately 60% (the estimated after-tax
cost to the Company) of the amount of such final payment. Prior to payment, such
estimated reimbursement was recorded as a "Stockholder Receivable" and as
"Additional Paid-in Capital".

NOTE 3 -- TRAK WEST ACQUISITION
 
     On December 8, 1997, the Company acquired a newly formed subsidiary ("Trak
West") of Trak Auto Corporation ("Trak Auto"). Upon its formation, Trak Auto
contributed to Trak West the fixtures and equipment, merchandise inventories and
store leases of 82 specific store sites in Southern California, together with
the merchandise inventory of the Ontario, California distribution center
operated by Trak Auto. After this contribution, Trak West had no liabilities and
owned no other assets than those previously described.
 
     The Company acquired Trak West for a total cost of approximately $34.5
million and financed its acquisition with a $22.0 million equity investment by
affiliates of the Company's existing stockholders and borrowings under the
Senior Credit Facility. In connection therewith, an affiliate of Investcorp was
paid a $1.0 million placement fee. In connection with the negotiation of the
Trak West acquisition, TG Investments, Ltd., an affiliate of Carmel, was paid a
$1.0 million consulting fee.
 
     The Trak West acquisition was accounted for under the purchase method of
accounting. Accordingly, the results of operations of these stores are included
in the consolidated operating

     No goodwill was recorded in connection with this acquisition.
 
     The Company incurred $3.4 million and $3.1 million of one time transition
and integration expenses during fiscal year 1997 and the twenty-six weeks ended
August 2, 1998, respectively, associated with the Trak West acquisition. Such
expenses included the costs of employee training, remerchandising and grand
opening advertising for the former Trak West stores.
 
NOTE 4 -- TRANSACTIONS AND RELATIONSHIPS WITH RELATED PARTIES
 
     During the years ended January 28, 1996 and February 2, 1997, the Company
received approximately $14.1 million and $18.5 million, respectively, of
proceeds from the sale of realty and fixtures to an affiliate at amounts that
equaled the Company's cost, which approximated fair market value. The related
assets were subsequently leased back by the Company under operating lease
arrangements. No such transactions occurred during fiscal 1997.
 
   
     In October 1989, the Company entered into a nine-year lease (the "Initial
Lease") for its corporate headquarters in Phoenix, Arizona, with an unaffiliated
landlord. The lease relates to approximately 78,577 square feet and provides for
a current base rent of approximately $1.49 million per year. During January
1994, Missouri Falls Holdings Corp., an affiliate of Carmel, acquired an
interest in the partnership ("Missouri Falls Partners") which acquired the
building and assumed the lease between the Company and the former landlord. In
April 1995, the Company assumed a lease (the "Subsequent Lease") between a
former tenant and Missouri Falls Partners for approximately 11,683 square feet
of additional office space at a current lease rent of $148,958 per year. In
connection with the 1996 Recapitalization, both the Initial Lease and the
Subsequent Lease were extended through October 2006. Additionally, the Company
rents approximately 5,754 square feet of additional space at these premises for
an annual rental of $106,449 under two separate lease documents with expiration
dates of February and March, 2000, respectively. The Company also leases certain
other facilities from related parties. The Company also leases from MFP
Holdings, LLC, an affiliate of Carmel, a parking lot

adjacent to its corporate headquarters for an annual rental of $62,506 under a
separate lease document with an expiration date of October 2006.
 
     The sum of approximately $15.5 million was paid to Transatlantic as of
December 27, 1996 pursuant to the Company's promissory note dated July 24, 1996.
The promissory note was issued to evidence a loan to the Company in the amount
of $15.0 million, the proceeds of which were used for the payment of amounts due
vendors.
 
     The Company paid Transatlantic, in April of 1998, the sum of $1.0 million
on account of fees for past financings.
 
     Pursuant to an agreement (the "Real Estate Agreement") entered into at the
closing of the 1996 Recapitalization, Transatlantic Finance, Ltd., an affiliate
of Carmel, or one or more of its affiliates (each a "Funding Company" and,
collectively, the "Funding Companies") may acquire and develop land and
buildings on sites selected by the Company and lease such sites to the Company
under operating leases. At the closing of each land purchase, a Funding Company,
as landlord, and the Company, as tenant, will enter into a triple net lease with
respect to such land and the buildings and improvements erected or to be erected
thereon. The obligation of the Funding Companies to acquire and develop
additional properties will cease when the cost of all such acquisitions
(including construction costs) exceeds $50.0 million, provided that as leased
properties are disposed of to third parties by the Funding Companies, funds
available to purchase additional properties will be replenished. The term of the
commitment for the investment in such land purchases and leases commenced on
October 30, 1996. On October 30, 1997, the Company notified Transatlantic of its
intent to terminate its participation in the facility as of February 1, 1998,
and replace it with the leasing facility more fully described in Note 7. As of
February 1, 1998, the Funding Company had 35 properties (which were undertaken
prior to the termination) in various stages of completion which reduced
availability under this facility by approximately $25.5 million.
 
     In connection with the 1996 Recapitalization, $40.0 million of the
Company's 12% Senior Subordinated Notes were acquired by a designee of the
Investcorp Group, Southwest Finance Limited ("Southwest Finance"), a company in
which an affiliate of Investcorp holds a minority interest. In connection with
the purchase of the 12% Subordinated Notes, Southwest Finance Limited received a
fee of $4.0 million. In addition, Transatlantic acquired $10.0 million of the
12% Subordinated Notes. Also, in connection with the 1996 Recapitalization,
Invifin S.A., an affiliate of Investcorp ("Invifin"), received a fee of $1.575
million for providing a standby commitment to fund the amount of the Senior
Credit Facility and the Company paid Investcorp International Inc.
("International") advisory fees of $1.275 million. The Company also paid $3.15
million to International for arranging the Senior Credit Facility.

services (the "Management Agreement") with International pursuant to which the
Company paid International at the closing of the 1996 Recapitalization $5.0
million for the entire term of the Management Agreement in accordance with its
terms. The Management Agreement was terminated in connection with the completion
of an initial public offering of the common stock of the Company, as more fully
described in Note 8. In connection with the termination of the agreement, the
Company recognized a charge to earnings of approximately $3.6 million during the

     On December 8, 1997, in connection with the consummation of the Trak West
acquisition, Auto amended and restated its Senior Credit Facility to provide
maximum borrowings of $300.0 million, subject to the limitations on the
incurrence of indebtedness under the indenture for Auto's 11% Senior
Subordinated Notes. As amended and restated, the Senior Credit Facility provides
for a $175.0 million term loan and a revolving credit facility with maximum
borrowings of $125.0 million. In addition to increasing the term loan and
revolving credit facility availability by $75.5 million and $25.0 million,
respectively, the amendment and restatement primarily provided for: (i) an
initial reduction in the interest rate for the term loan and the revolving
credit facility and the introduction of a pricing grid which periodically
permits adjustment based upon Auto's degree of leverage; (ii) the elimination of
the previous borrowing base restrictions on revolving credit borrowings; (iii)
capital expenditure "baskets" for the Trak West acquisition and for up to $50.0
million of other acquisitions subject to pro forma compliance with financial
covenants; and (iv) a $50.0 million revolving capital expenditure "basket" of
funds that can be used by Auto to finance store purchase and development
activities. The term loan portion of the Senior Credit Facility matures on
October 31, 2003 and the revolving credit portion matures on October 31, 2001.
 
     The Company recognized an extraordinary charge of $5.1 million ($3.0
million net of income taxes) in the fourth quarter of fiscal 1997 to reflect the
write-off of certain deferred financing costs associated with the early
extinguishment of the original Senior Credit Facility.
 
     Borrowings under the Senior Credit Facility are collateralized by a first
priority security interest in substantially all of the personal property of
Auto, subject to certain permitted liens. The Company also issued a guarantee of
such borrowings under the Senior Credit Facility, which guarantee is
collateralized by a pledge by the Company of all issued and outstanding capital

stock of Auto. Each of the United States subsidiaries of Auto, Schuck's
Distribution Co., Kragen Auto Supply Co. and TRK Socal, Inc., also issued a
guarantee under the Senior Credit Facility which is collateralized by a first
priority security interest in substantially all personal property of such
subsidiary, and Auto pledged the issued and outstanding capital stock of each of
these subsidiaries. On April 8, 1998, Schuck's Distribution Co., Kragen Auto
Supply Co. and TRK Socal, Inc. were merged into Auto.
 
     The Senior Credit Facility prohibits, with certain limited exceptions, the
optional or mandatory prepayment or other defeasance of Auto's 11% Senior
Subordinated Notes. The Senior Credit Facility further requires that, under
certain circumstances, Auto make prepayments of the term loan outstanding
thereunder with (i) 50% of any Excess Cash Flow (as defined therein) and (ii)
50% of the Net Proceeds (as defined therein) from certain offerings of the
Company's voting stock. In addition, a "change of control" allows the lenders to
accelerate the loans. A change of control occurs whenever anyone acquires the
power to vote at least 30% of the common stock, on a fully diluted basis (as
defined), and holds a greater percentage of shares of common stock than the
Investcorp Group. A change of control also occurs if a majority of the Board of
Directors ceases to be composed of Investcorp Group nominees.
 
     Commitment fees on available funds under the Revolving Credit Commitment
are payable quarterly in arrears on the average daily unused amount of the total
commitment at the rate of 1/2 of 1% per annum. Commitment fees totaling $104,000
and $194,000 were incurred in fiscal 1996 and 1997, respectively. The commitment
fee rate decreased to 3/8 of 1% per annum in December 1997.
 
     The terms of the Senior Credit Facility include restrictions on
investments, capital expenditures, dividends and certain other payments and
require the Company to meet certain financial covenants. The Company believes it
was in compliance with all such covenants at February 1, 1998.
 
  11% SENIOR SUBORDINATED NOTES DUE 2006
 
     On October 30, 1996, Auto issued and sold in a private placement $125.0
million aggregate principal amount of 11% Senior Subordinated Notes due 2006
(the "Old 11% Notes") pursuant to an indenture, between Auto and The Bank of New
York (as successor to Wells Fargo Bank, N.A.), as Trustee. On March 13, 1997,
Auto offered to exchange up to all outstanding Old 11% Notes for a like
principal amount of its 11% Series A Senior Subordinated Notes due 2006 (the
"11% Senior Subordinated Notes") issued pursuant to the Indenture in a
transaction registered under the Securities Act of 1933, as amended. Auto
consummated the exchange offer on June 18, 1997, with all of the Old 11% Notes
being exchanged for the 11% Senior Subordinated Notes.

     The indenture restricts Auto from making additional borrowings under its
Revolving Credit Commitment that, when added to the aggregate amount of
outstanding borrowings under the Senior Credit Facility (including term loans),
exceed $200.0 million. This restriction does not apply if the new borrowings are
of a type specifically permitted by the indenture, or, if after giving pro forma
effect to such new borrowings the ratio of Auto's consolidated EBITDA to fixed
charges (as such terms are defined in the indenture) exceeds 2.25 to 1.
 
     The indenture also provides that upon a "change of control," each holder of
11% Senior Subordinated Notes will have the right to require CSK Auto, Inc. to
repurchase all or any part of such holder's notes at a purchase price in cash
equal to 101% of the principal amount plus accrued and unpaid interest, if any,
to the date of purchase.
 
     The 11% Senior Subordinated Notes bear interest at 11% per year, payable
semiannually in arrears on each May 1 and November 1, and mature on November 1,
2006. The 11% Senior Subordinated Notes are general, unsecured senior
subordinated obligations. The 11% Senior Subordinated Notes were guaranteed
fully, unconditionally and jointly and severally by all of Auto's subsidiaries
and will be similarly guaranteed by any future United States subsidiaries of
Auto, on a senior subordinated basis. On April 8, 1998, Auto's subsidiaries were
merged into Auto.
 
     On and after November 1, 2001, the 11% Senior Subordinated Notes will be
redeemable, at the option of Auto, in whole or in part, upon not less than 30
nor more than 60 days' notice, at the redemption prices set forth below

     The 12% Subordinated Notes bear interest at 12% per year, payable
semiannually in arrears on each April 30 and October 31, and mature on October
31, 2008. The 12% Subordinated Notes are general, unsecured senior subordinated
obligations of the Company. The 12% Subordinated Notes are subordinated to all
senior indebtedness of the Company, including the Company's guarantee of the
Senior Credit Facility. The Series A Notes and Series B Notes rank pari passu
with one another.
 
     The 12% Subordinated Notes are redeemable at any time and from time to
time, at the option of the Company, in whole or in part, upon not less than 30
nor more than 60 days' notice, at a redemption price of 101% of the principal
amount redeemed, plus accrued and unpaid interest thereon, if any, to the
redemption date.

NOTE 6 -- LONG TERM DEBT, CONTINUED
     As more fully described in Note 9, the Company completed an initial public

</TABLE>
 
     Upon the consummation of the offering, the Company recorded an
extraordinary loss of approximately $6.9 million, net of taxes. Such
extraordinary loss consists primarily of the premiums paid in connection with
the redemption of indebtedness and the write-off of a portion of deferred debt
issuance costs.
 
NOTE 7 -- LEASES
 
     The Company leases its office and warehouse facilities and a majority of
its stores and equipment. Generally, store leases provide for minimum rentals
and the payment of utilities, maintenance, insurance and taxes. Certain store
leases also provide for contingent rentals based upon a percentage of sales in
excess of a stipulated minimum. The majority of lease agreements are for base
lease periods ranging from 15 to 20 years, with three to five renewal options of
five years each.
 
     On November 18, 1997, the Company reached an agreement with an unrelated
third party for the establishment of a $125.0 million operating lease facility
for the acquisition and development of approximately 100 to 125 new stores over
the period from February 1, 1998 through May 31, 1999.

of 100 shares) was then redeemed at an aggregate redemption price of
approximately $238.5 million. Concurrently therewith, the Company issued
8,381,450 shares of Class E stock to Carmel at an issue price of $100.9 million.
See Note 2.
 
     In December 1997, the Company sold 180,600 shares of its Class B stock to

NOTE 8 -- CAPITAL STOCK AND INITIAL PUBLIC OFFERING, CONTINUED
     On March 17, 1998, the Company completed an initial public offering (the
"Offering") of approximately 8.6 million shares of its common stock, generating
proceeds of approximately $159.1 million, net of offering expenses. The offering
proceeds were used to retire the Company's 12% Subordinated Notes and other
indebtedness as more fully described in Note 6. Upon retirement of the 12%
Subordinated Notes, all of the outstanding preferred stock of Auto was
cancelled.
 
     In connection with the Offering, the Company's Board of Directors and
stockholders approved a 17.105 to 1 stock split effected in the form of a stock
dividend. Accordingly, all share and option information contained herein has
been adjusted to give retroactive effect to such stock split. In addition, under
the terms of the Company's restated Certificate of Incorporation in effect at
the time of the Offering, each share of each class of issued and outstanding
capital stock of the Company automatically converted to common stock upon the
consummation of the Offering on March 17, 1998.
 
     The Company's capital stock, as adjusted for the stock split discussed
above, consists of the following:

  RETIREMENT PROGRAM
 
   
     The Company sponsors a 401(k) plan which is available to all employees of
the Company who have completed one year of continuous service. Effective October
1, 1997, the Company matches from 40% to 60% of employee contributions in 10%
increments, based on years of service with the Company, up to 4% of the
participant's base salary. Prior to October 1, 1997, the Company matched 20% of
employee contributions, up to 6% of the participant's base salary, without
regard to years of service. Participant contributions are subject to certain
restrictions as set forth in the Internal Revenue Code. The Company's matching
contributions totaled $267,000, $288,000 and $394,500 for fiscal years 1995,
1996 and 1997, respectively.
    
 
  1996 STOCK OPTION PLANS
 
     On October 30, 1996, the Company awarded options to purchase shares of
common stock under its Associate Stock Option Plan (the "Associate Plan") and
its Executive Stock Option Plan (the "Executive Plan" and together with the
Associate Plan, the "Plans") in order to provide incentives to store managers
and salaried corporate and warehouse employees of the Company. In October 1996
and February 1997, the Company's Board of Directors approved the Associate Plan
and the Executive Plan, respectively.
 
     The Plans may be administered by a committee of the Board of Directors of
the Company, which would have broad authority in administering and interpreting
the Plans, or, if a committee has not been appointed, by the entire Board of
Directors. The Plans provide that, at such time as the Company has a class of
equity securities registered under Section 12 of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), the committee must consist entirely of
"Non-Employee Directors" (as defined in Rule 16b-3 under the Exchange Act). A
committee has not yet been appointed to administer the Plans.
 
     Options to purchase up to an aggregate of 1,026,300 and 684,200 shares of
common stock may be granted under the Associate Plan and the Executive Plan,
respectively. Options granted under the Plans may be options intended to qualify
as incentive stock options under Section 422 of the Internal Revenue Code of
1986, as amended, or options not intended to so qualify. In the event of a sale
of more than 80% of the outstanding shares of capital stock of the Company or
80% of its assets, the vested portion of an option and, under certain
circumstances, the unvested portion will be purchased by the Company. All
options expire on the seventh anniversary of the date of grant (or, under
certain circumstances, 30 days later).
 
     As a result of the Offering, each option granted under the Plans will
become exercisable upon vesting. Options granted under the Associate Plan vest
in three equal installments on the second, third and fourth anniversaries of the
date of their grant, assuming the associate's employment continues during this
period ("Four Year Vesting"). Options granted under the

Executive Plan are subject to the Four Year Vesting as to 84% of such options
and performance vesting (over the same four years) as to the remaining 16%. The
performance vesting criteria is based upon achieving specified operating
results. Partial vesting of options subject to performance vesting occurs if the
Company achieves less than 95% of the specified operating results. Any portion
of options granted under the Executive Plan which are subject to performance
vesting and which do not vest during the four years will automatically vest 90
days prior to the end of the option's term. If the specified operating results
are exceeded for any year by at least 10%, the executive will receive options
for up to an additional 5% (20% on a cumulative basis) of his or her original
option grant (no such additional options have been granted).
 
     As of February 1, 1998, the Company has granted options to purchase 679,151
shares under the Associate Plan and 385,622 shares under the Executive Plan, net
of cancellations. The exercise price applicable to these options is $12.04 per
share with respect to 993,833 shares and the exercise price is $20.00 with
respect to 70,940 shares. Except for 96,062 options granted under the Executive
Plan (see "Employment Agreements" below), these exercise prices represent the
fair market value at the date of grant based upon the price paid for such shares
in the 1996 Recapitalization and other valuation analyses performed by the
Company, or the Offering, as applicable.
 
  DIRECTORS STOCK PLAN
 
     In June 1998 the Company's Board of Directors adopted a non-employee
director compensation plan, subject to shareholder approval. The plan provides
for an aggregate of up to 50,000 shares in the form of restricted stock grants
or stock options. The Board of Directors has adopted a policy which provides
each non-employee director with an annual stipend of $25,000, of which at least
$10,000 must be paid in the form of restricted stock grants.
 
  EMPLOYMENT AGREEMENTS
 
     Auto has entered into employment agreements with the Chairman and the
President pursuant to which they are paid fixed base salaries and are eligible
for bonuses based upon earnings before interest, taxes, depreciation and
amortization ("EBITDA") and, in the case of the Chairman, an additional bonus at
the discretion of the Board of Directors. The agreements do not contain stated
termination dates, but rather are terminable at will by either party. If Auto
were to terminate the employment of the Chairman and President without cause, or
if they terminate their employment for good reason, Auto has agreed to pay to
the Chairman his base salary and performance bonus for a period of 24 months and
to the President his base salary for one year. The Chairman also received a loan
of $550,000 from the Company, bearing interest at 4.535% and due in 1999.

NOTE 9 -- EMPLOYEE BENEFIT PLANS, CONTINUED
     In connection with the commencement of his employment, the Company agreed
to pay the Chairman $1.0 million which, in turn, was used by the Chairman to
purchase 83,079 shares of common stock from a member of the Investcorp Group,
reflecting a share value of $12.04, the fair market value at the date of the
agreement, based on the price paid for such shares in the 1996 Recapitalization.
Under the Chairman's employment agreement, the shares vested 50% upon
commencement of employment with an additional 25% vesting at each of the first
and second anniversary of the agreement. The Company has also loaned the
Chairman approximately $440,000 to pay the income tax consequences of the award.
The loan bears interest at the rate applicable to borrowings under the Revolving
Credit Commitment, and is due in 2000.
 
     In connection with the execution of his employment agreement, the Company's
Chairman received an option for 401,967 shares of common stock, exercisable at
$12.04 per share. As a result of vesting acceleration triggered by the Offering,
this option will generally vest and become exercisable in March 2000, subject to
earlier vesting based upon the achievement of certain EBITDA targets and the
occurrence of other specified events. In connection with the Trak West
acquisition, the Company's Chairman received an option for 39,940 shares of
common stock, exercisable at $12.04 per share, effective as of February 1, 1998.
This option will vest and become exercisable in four equal annual installments
beginning in April 1999. In connection with the issuance of these options, the
Company will recognize a charge to earnings of approximately $0.2 million over
the vesting period for the difference between the exercise price and the fair
market value of the common stock at the date of grant. In connection with the
Offering, the Company's Chairman received an option for 216,634 shares of common
stock, exercisable at $20.00 per share, the fair market value at the date of
grant based on the Offering. This option will vest and become exercisable in
three equal annual installments beginning in April 2000.
 
     In connection with the execution of his employment agreement, the Company's
President received an option for 299,337 shares of common stock, exercisable at
$12.04 per share. This option has both vested and become exercisable to the
extent of 42,762 shares. As a result of vesting acceleration triggered by the
Offering, the remainder of this option will generally vest and become
exercisable in March 2000, subject to earlier vesting based upon the achievement
of certain EBITDA targets and the occurrence of other specified events.
 
  MANAGEMENT STOCK PURCHASE AGREEMENTS AND LOANS PLANS
 
     In December 1997, the Company entered into stock purchase agreements with
certain executives of the Company. Under the terms of the agreements, the
Company agreed to issue a total of 180,600 shares of its common stock at a price
of $12.04 per share, the same price paid in the 1996 Recapitalization. In
addition, the Company granted certain executives non-qualified options to
purchase 96,062 shares of its common stock, also at a price of $12.04 per share.
The options contain similar terms and vesting provisions as existing options
under the Company's

Executive Stock Option Plan. In connection with issuance of these shares, the
Company recognized a charge to earnings of $0.9 million in the fourth quarter of
fiscal 1997 for the difference between the issuance price and the fair market
value of the stock at the date of sale. In addition, in the fourth quarter of
fiscal 1997, the Company recorded deferred compensation of approximately $0.5
million to reflect the difference between the exercise price and the fair market
value of stock associated with the options granted to certain executives. The
deferred compensation will produce a charge to earnings over the vesting period
of the options.
 
     Of the total consideration paid to the Company of $2.2 million in
connection with the purchase of the Company's common stock by certain
executives, approximately $1.0 million was loaned by the Company to certain
executives to purchase 84,550 of the shares (the "Stock Loans"). The Stock Loans
are collateralized by the stock under pledge agreements, provide full recourse
to the executive, bear interest at the average rate paid by the Company under
the revolving portion of its Senior Credit Facility, and mature in December
2003.

     The Company has recorded deferred tax assets of approximately $10.2 million

expiration of the loss carryforwards. Utilization of certain of the net
operating loss carryforwards may be limited under Section 382 of the Internal
Revenue Code. Although realization is not assured, management believes it is
more likely than not that all the deferred tax assets will be realized.
Accordingly, the Company believes that no valuation allowance is required for
deferred tax assets in excess of deferred tax liabilities. The amount of the
deferred tax assets considered realizable, however, could be reduced in the near
term if estimates of future taxable income during the carryforward period are
reduced.

     In January 1997, the Company updated its strategic plan relating to the
relocation of certain stores. As a result of the 1996 Recapitalization, the
Company obtained greater access to capital resources including the availability
of a sale-leaseback facility for new stores, thereby improving the Company's
ability to implement such relocations. While management believes that there will
be long-term operating benefits from this strategy, the Company will incur costs
for early lease terminations or negative sub-lease rentals for stores vacated
under this plan and, accordingly, a charge to earnings of approximately $12.9
million was recorded in January 1997.
 
     Store closing costs include estimates for vacancy periods of the related
stores through the expiration of the underlying leases, collectibility of rents
due from sub-tenants, and similar factors.
 
NOTE 13 -- LEGAL MATTERS
 
     The Company was served with a lawsuit that was filed in the Superior Court
in San Diego, California on May 4, 1998. The case is brought by two former store
managers and a former assistant manager. It purports to be a class action for
all present and former California store managers and senior assistant managers
and seeks overtime pay for a period beginning in May of 1995 as well as
injunctive relief requiring overtime pay in the future. This case is in early
stages of discovery. The Company has recently been served with two other
lawsuits purporting to be class actions filed in California state courts in
Orange County and Fresno, California by thirteen other former and current
employees. These lawsuits include similar claims to the San Diego

lawsuit, except that they also include claims for unfair business practices, and
the Orange County lawsuit includes a claim for punitive damages based on an
unlawful conversion theory. If these cases are permitted by the courts to
proceed as a class action and are decided adversely, the Company's aggregate
potential exposure could be material to its results of operations for the year
in which the cases are ultimately decided. The Company does not believe,
however, that such an adverse outcome, if it were to happen, would materially
affect its financial position or its operations in subsequent periods. The
Company believes it has meritorious defenses to all of these cases and intends
to defend them vigorously.
    
 
     The Company is a defendant in various other legal matters arising from
normal business activities. Management believes that the ultimate outcome of
these matters will not have a material effect on the Company's results of
operations, financial position or cash flows.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law (the "DGCL") makes
provisions for the indemnification of officers and directors of corporations in
terms sufficiently broad to indemnify the officers and directors of the
registrant under certain circumstances from liabilities (including reimbursement
of expenses incurred) arising under the Securities Act of 1933, as amended (the
"Securities Act").
 
     As permitted by the DGCL, the registrant's Amended and Restated Certificate
of Incorporation, as amended (the "Charter"), provides that, to the fullest
extent permitted by the DGCL, no director shall be liable to the registrant or
to its stockholders for monetary damages for breach of his fiduciary duty as a
director. Delaware law does not permit the elimination of liability (i) for any
breach of the director's duty of loyalty to the registrant or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) in respect of certain unlawful
dividend payments or stock redemptions or repurchases, or (iv) for any
transaction from which the director derives an improper personal benefit. The
effect of this provision in the Charter is to eliminate the rights of the
registrant and its stockholders (through stockholders' derivative suits on
behalf of the registrant) to recover monetary damages against a director for
breach of fiduciary duty as a director thereof (including breaches resulting
from negligent or grossly negligent behavior) except in the situations described
in clauses (i)-(iv), inclusive, above. These provisions will not alter the
liability of directors under federal securities laws.
 
     In addition, the Charter provides that the registrant may indemnify any
person who was or is a party or who was or is threatened to be made a party to
or is otherwise involved in any threatened, pending or completed action, suit or
proceeding (including, without limitation, one by or in the right of the
registrant to procure judgment in its favor), whether civil, criminal,
administrative or investigative, by reason of the fact the he or she is or was a
director, officer, employee or agent of the registrant or is or was serving at
the request of the registrant as a director, officer, employee or agent of any
other corporation or enterprise, from and against any
 
                                      II-1
<PAGE>   118
 
and all expenses (including attorney's fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person. The Charter also
provides that the indemnification provided in the Charter shall not be deemed
exclusive of any other rights to which the indemnified party may be entitled and
that the registrant may maintain insurance, at its expense, to protect itself
and any director, officer, employee or agent of the registrant or any other
corporation or enterprise against expense liability or loss whether or not the
Registrant would have the power to indemnify such person against such expense,
liability or loss under the DGCL or under the Charter.
 
     The registrant's Amended and Restated By-Laws (the "Bylaws") provide that
the registrant may indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the registrant) by reason of the fact that he is
or was a director, officer, employee or agent of the registrant or is or was
serving at the request of the registrant as a director, officer, employee or
agent of any other corporation or enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding if such person acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the registrant, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe such person's conduct was unlawful.
 
     The Bylaws also provide that the registrant may indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action or suit by or in the right of the registrant to procure
judgment in its favor by reason of the fact that such person acted in any of the
capacities set forth above, against expenses (including attorneys' fees)
actually and reasonably incurred by such person in connection with the defense
or settlement of such action or suit if such person acted under similar
standards, except that no indemnification may be made in respect of any claim,
issue or matter as to which such person shall have been adjudged to be liable to
the registrant unless and only to the extent that the Court of Chancery of the
State of Delaware or the court in which such action or suit was brought shall
determine that despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to be
indemnified for such expenses which the Court of Chancery of the State of
Delaware or the court in which such action was brought shall deem proper.
 
     The Bylaws also provide that to the extent a director or officer of the
registrant has been successful in the defense of any action, suit or proceeding
referred to in the previous paragraphs or in the defense of any claim, issue, or
matter therein, he shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection therewith and that
indemnification provided for in the Bylaws shall not be deemed exclusive of any
other rights to which the indemnified party may be entitled.

          (g) On December 8, 1997, the registrant issued and sold approximately
     52,360 (895,618 giving effect to the Stock Split) shares of Class E Common

     effect to the Stock Split) per share, or an aggregate offering price of
     approximately $10,786,160.
 
          (h) On various dates from October 30, 1996 through November 2, 1997,
     pursuant to the registrant's 1996 Associate Stock Option Plan and the
     registrant's 1996 Executive Stock Option Plan (collectively, and as amended
     from time to time, the "Plans"), the Company awarded to key employees of
     CSK Auto, Inc. non-qualified incentive stock options, exercisable in whole
     or in part at approximately $206 ($12.04 giving effect to the Stock Split)
     per share, to purchase an aggregate of 52,691 (901,279 giving effect to the
     Stock Split) shares of Class B Common Stock ("Class B Shares"). On the
     closing of the registrant's initial public offering, each option became

                                      II-3
<PAGE>   120
 
shares of common stock to the number of Class B Shares for which it was
exercisable prior to the offering, at the same price per share.
 
          (i) On various dates from November 3, 1997 through February 16, 1998,
     pursuant to the 1996 Executive Stock Option Plan, the registrant issued

     in part at approximately $206 ($12.04 giving effect to the Stock Split) per
     share, to purchase 99 (1,693 giving effect to the Stock Split) Class B
     Shares. On the closing of the registrant's initial public offering, each
     option became exercisable for an identical number of shares of common stock
     as the number of Class B Shares for which it was exercisable prior to the
     offering, at the same price per share.
 
          (j) On various dates from November 3, 1998 through February 16, 1998,
     pursuant to the 1996 Associate Stock Option Plan, the registrant issued
     additional non-qualified incentive stock options, exercisable in whole or
     in part at approximately $342 ($20.00 giving effect to the Stock Split) per
     share, to purchase 4,689 (80,205 giving effect to the Stock Split) Class B
     Shares. On the closing of the registrant's initial public offering, each
     option became exercisable for an identical number of shares of common stock
     as the number of Class B Shares for which it was exercisable prior to the
     offering, at the same price per share.
 
          (k) In connection with the execution of his employment agreement in

     the Stock Split) per share for 17,500 (299,337 giving effect to the Stock
     Split) shares of Class B Stock. On the closing of the registrant's initial
     public offering, each option became exercisable for an identical number of
     shares of common stock as the number of Class B Shares for which it was
     exercisable prior to the offering, at the same price per share.
 
          (l) In connection with the execution of his employment agreement in
     January 1997, the registrant granted Maynard Jenkins an option exercisable
     in whole or in part at a price of approximately $206 ($12.04 giving effect
     to the Stock Split) per share for 23,500 (401,967 giving effect to the
     Stock Split) shares of Class B Stock. On the closing of the registrant's
     initial public offering, each option became exercisable for an identical
     number of shares of common stock as the number of Class B Shares for which
     it was exercisable prior to the offering, at the same price per share.
 
          (m) In December 1997, 22 members of the registrant's management

     the Stock Split) per share, or an aggregate offering price of approximately
     $2,175,154, pursuant to Management Stock Purchase Agreements. These
     individuals received secured loans from the registrant pursuant to its 1997
     Stock Loan Program in an aggregate amount equal to the purchase price of
     4,943 (84,550 giving effect to the Stock Split) Class B Shares, or an
     aggregate principal amount of approximately $1,018,258. At the time of
     these purchases, the registrant agreed to grant one non-qualified stock
     option exercisable in whole or in part at approximately $206 ($12.04 giving
     effect to the Stock Split) in respect of each Class B Share, purchased
     without the benefit of the 1997 Stock Loan Program, to such purchasers, for
     a total of 5,616 (96,061

giving effect to the Stock Split) Class B Shares. On the closing of the
registrant's initial public offering, each option became exercisable for an
identical number of shares of common stock as the number of Class B Shares for
which it was exercisable prior to the offering, at the same price per share.
 
          (n) In February 1998, the registrant granted Maynard Jenkins an
     option, exercisable in whole or in part at a price of approximately $206
     ($12.04 giving effect to the Stock Split) per share for 2,335 (39,940
     giving effect to the Stock Split) shares of Class B Stock. On the closing
     of the registrant's initial public offering, each option became exercisable
     for an identical number of shares of common stock as the number of Class B
     Shares for which it was exercisable prior to the offering, at the same
     price per share.
 
          (o) In February 1998, the registrant granted Maynard Jenkins an
     option, exercisable in whole or in part at a price of approximately $342
     ($20.00 giving effect to the Stock Split) per share for 12,665 (216,634
     giving effect to the Stock Split) shares of Class B Stock. On the closing
     of the registrant's initial public offering, each option became exercisable
     for an identical number of shares of common stock as the number of Class B
     Shares for which it was exercisable prior to the offering, at the same
     price per share.
 
     The transaction set forth in paragraph (a) above was undertaken in reliance
upon the exemption from the registration requirements of the Securities Act
afforded by Section 3(a)(9) thereof. The transactions set forth in paragraphs
(b) through (g) above were undertaken in reliance upon the exemption from the
registration requirements of the Securities Act afforded by Section 4(2) thereof
and/or Regulation D promulgated thereunder, as sales not involving a public
offering. The transactions set forth in paragraphs (h) through (o) above were
undertaken in reliance upon the exemption from the registration requirements of
the Securities Act afforded by Rule 701 promulgated under the Securities Act, as
sales by an issuer to employees, directors, officers, consultants or advisors
pursuant to written compensatory benefit plans or written contracts relating to
the compensation of such persons. The purchasers of the securities described
above acquired them for their own account and not with a view to any
distribution thereof to the public. The certificates evidencing the securities
bear legends stating that the shares may not be offered, sold or transferred
other than pursuant to an effective registration statement under the Securities
Act or an exemption from such registration requirements. The registrant believes
that exemptions other than those specified above may exist with respect to the
transactions set forth above. On September 15, 1998, the registrant filed a
registration statement on Form S-8 to register the issuance of shares of common
stock pursuant to the exercise of options granted in the transactions described
in paragraphs (h) through (j) and (m) above.

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