VOTING AND ATTENDANCE
 
  Voting at the Annual Meeting
 
     In order to obtain a quorum (the minimum number of Stockholders required to
take valid action) at the Annual Meeting, holders of a majority of the issued
and outstanding shares of common stock of CSK Auto Corporation entitled to vote
must attend, either in person or by proxy. In accordance with Delaware law, if a
stockholder abstains from voting on an action, that stockholder's shares will
still be counted for determining whether the requisite number of stockholders
attended the meeting. If a broker does not vote on any particular action because
it does not have the authority to do so, but does vote on other actions, the
shares will still be counted for determining whether the requisite number of
stockholders attended the meeting.
 
     All actions to be taken at the Annual Meeting, including the election of
directors, shall be decided by an affirmative vote of the holders of a majority
of shares of common stock issued and outstanding. As a result, any shares not
voted (whether by abstentions, broker non-vote or otherwise) have the effect of
a vote "AGAINST" such actions.
 
     All valid proxies received by the Company pursuant to this solicitation
will be voted in accordance with the instructions specified in the proxy. If no
such instructions have been specified, the shares will be voted "FOR" each of
the Company's nominees for election to the Board of Directors and "FOR" each of
the other matters discussed in this Proxy Statement.
 
     We do not know of any matters to be acted upon at the meeting other than
those discussed in this Proxy Statement. If other matters properly come before
the Annual Meeting, it is the intention of the persons named in the solicited
proxy to vote on such matters in accordance with their judgment as to the best
interests of the Company.
 
     Any stockholder who has executed and returned a proxy and who for any
reason desires to revoke such proxy may do so at any time before the proxy is
exercised (i) by delivering written notice prior to the Annual Meeting to the
Secretary of the Company at the above address, (ii) by voting the shares
represented by such proxy in person at the Annual Meeting, or (iii) by giving a
later dated proxy at any time before the voting. Attendance at the Annual
Meeting, will not, by itself, revoke a proxy.
 
  Voting in Person
 
     If you wish to attend the Annual Meeting in person, you must have an
admission ticket issued in your name. Advance ticket requests must be submitted
in writing and received by CSK Auto Corporation on or before June 1, 1999. No
requests will be processed after that date. Submit requests to Lon Novatt,
Secretary, by mail at 645 East Missouri Avenue, Phoenix, Arizona 85012. Tickets
will be available at the door for stockholders of record on the record date and
for such stockholders' authorized proxy holders. Each stockholder of record on
the record date, or such stockholder's authorized proxy holder, is entitled to
bring one guest.
 
  Voting by Proxy
 
     If you properly execute the enclosed proxy card and return it in time for
the Annual Meeting, your proxy will be considered validly given. CSK Auto
Corporation is also offering stockholders the opportunity to vote by telephone.
Instructions for stockholders interested in using this method to vote are set
forth in the enclosed proxy materials.
 
EXPENSES OF SOLICITATION
 
     The costs of solicitation of proxies will be borne by the Company. Such
costs include preparation, printing, and mailing of the Notice of Annual Meeting
of Stockholders, this Proxy Statement, the enclosed proxy card and the Company's
Annual Report on Form 10-K for fiscal 1998, and the reimbursement of brokerage
firms and others for reasonable expenses incurred by them in connection with the
forwarding of proxy solicitation materials to beneficial owners. The
solicitation of proxies will be conducted primarily by mail, but may include
telephone, facsimile or oral communications by directors, officers, or regular
employees of the Company acting without special compensation.

     The thirteen individuals named in the table below are the Company's
nominees for election to the Board of Directors. Each of the nominees currently
serves on the Company's Board of Directors. Our directors are elected for terms
of one year and will hold office until the next annual meeting of our
stockholders or until his or her successor has been elected and qualified. At
the Annual Meeting, all directors will be elected to serve until the 2000 Annual
Meeting of Stockholders.
 
     Each of the nominees has consented to being named as a nominee in this
Proxy Statement and has agreed to serve if elected. Should any nominee become
unable or unwilling to serve for any reason, it is intended that the persons
named in the solicited proxy will vote for the election of such other person as
may be designated by the Board of Directors.
 
     The nomination and election of directors is subject to the provisions of a
stockholders' agreement. As of April 30, 1999, the Company and stockholders
owning approximately 43% of our outstanding common stock were party to this
stockholders' agreement. This stockholders' agreement provides that a group of
companies affiliated or associated with Investcorp S.A. (the "Investcorp Group")
is entitled to nominate a majority (currently seven) of our nominees for the
Board of Directors and The Carmel Trust ("Carmel") and its affiliates
(collectively with Carmel, the "Carmel Group") are entitled to nominate the
remainder of the nominees. In addition, each of the parties to the stockholders'
agreement has agreed to vote all of its shares in favor of each of the persons
nominated to the Board of Directors by the other parties. A more complete
description of this stockholders' agreement is contained in this Proxy Statement
under the caption "Certain Relationships and Related Transactions."

     In order to ensure consistent reimbursement and compensation of our outside
directors, including the application of the Directors Plan, in October 1998 our

Antioco and Godlas are currently compensated under this policy. This policy
provides for an annual stipend of $25,000, at least $10,000 of which must be
paid in the form of restricted stock grants pursuant to our Directors Plan. The
annual stipend is pro-rated from the time of the director's election to the
proposed date for our next annual meeting of stockholders. Awards of restricted
stock are valued at fair market value at the close of business on the date
immediately prior to the date of the grant. As of April 30, 1999, we have
granted 1,516 shares of restricted common stock under the Directors Plan. These
grants are contingent on stockholder approval of the Directors Plan and, if such
approval is not obtained, shall be of no effect.
 
     The outside director compensation policy also provides for a cash stipend
of $1,500 for attending each meeting of our Board of Directors and any meeting
of a committee that is not held in conjunction with a meeting of the whole
Board. We also reimburse our outside directors for the costs of attending Board
of Directors meetings.
 
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 October 1996, 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 October
       1996, 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 to a total annual rent of $221,510.
 
     - We lease approximately 5,754 square feet of additional space at the above
       premises for an annual rental of $106,449 under three 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 January 31, 1999
       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 $4.8 million of the fixture
       sale-leasebacks with similar arrangements with unrelated third parties.
       As of January 31, 1999, there were approximately $1.0 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.
 
     - Beginning in October 1996, we entered into a series of sale-leaseback
       transactions with Transatlantic Leasing, Inc. ("Leasing"), another
       affiliate of Carmel, for certain real property. The terms of the leases
       under the facility with Leasing were set in arm's-length negotiations. As
       of January 31, 1999, the net
 
                                        6
<PAGE>   9
 
       funding provided by Leasing in these transactions was approximately $0.9
       million. In October 1997, we established a new sale-leaseback facility
       and we terminated the facility with Leasing.
 
     In connection with a recapitalization in 1996, 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 initial public offering to
redeem the 12% subordinated notes, including a redemption premium of $0.5
million.
 
     From time to time, we have paid fees to related parties for financing,
management consulting, commitment and equity placement services.
 
     - In April 1998, we paid Transatlantic $1.0 million in fees for past
       financings.
 
     - In October 1996, we entered into a five-year agreement for management
       advisory and consulting services with Investcorp International Inc., an
       affiliate of Investcorp. We paid Investcorp International $5.0 million in
       advance for the entire term of the management agreement. In accordance
       with its terms, the management agreement terminated upon our initial
       public offering.
 
     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 his engagement as Chief Executive Officer, we loaned 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 4.545%. This loan was authorized by the Board of Directors prior to the
commencement of Mr. Jenkins' employment.
 
     In connection with his engagement as Chief Executive Officer, we also
loaned Mr. Jenkins $441,500 to pay the state and federal income taxes he
incurred in connection with a $1,000,000 cash bonus that he used to purchase
shares of common stock from a member of the Investcorp Group. This loan was
repaid in fiscal 1998 by Mr. Jenkins with a portion of his proceeds from the
sale of this stock in a registered public offering.
 
  Stockholders' Agreement
 
     At the time of our recapitalization in October 1996 (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 Limited, an affiliate of Investcorp, and their subsequent
transferees, 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"), (2) pursuant to a registered
public 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 Stockholders on terms and conditions established by the selling
Agreeing Stockholder. In the event that we and/or the other
                                        7
<PAGE>   10
 
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 these purposes, 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.
 
     Registration Rights.  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. In connection with the
registered offering of our common stock in December 1998, the Investcorp Group
exercised one of its Demand Rights and the Carmel Group agreed that the next
registered offering of common stock by both the Investcorp Group and the Carmel
Group that is made pursuant to an exercise of Demand Rights shall be deemed to
be pursuant to an exercise by the Carmel Group.
 
     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.
 
     Election of Directors.  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'
 
                                        8
<PAGE>   11
 
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.
 
     Termination.  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.
 
         REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION
 
COMPENSATION POLICIES
 
     The Compensation Committee establishes compensation guidelines and targets
based upon the performance of CSK Auto Corporation and individual executive
officers. Compensation ranges are established through periodic evaluation of the
duties and responsibilities assigned to employees of various positions and a
review of the compensation paid in the general market for persons with the same
or similar skills, training and ability, performing similar duties. We
periodically adjust salary ranges based upon duties performed, business growth,
general economic conditions of the Company and comparable wages and salaries.
The Compensation Committee's goal is to establish a compensation program that:
 
     - Links the interests of management and stockholders;
 
     - Links executive compensation with long-term CSK performance; and
 
     - Attracts and retains executives of high caliber and ability.
 
     For fiscal 1998, the Company's compensation program consisted of base
salary, an incentive bonus plan, a stock option plan and a retirement plan. The
Compensation Committee believes this compensation program was a significant
factor contributing to our success this past year.
 
  Base Salary
 
     Each year the Compensation Committee reviews base salaries of individual
executive officers and their salary ranges. In determining adjustments to base
salary and salary ranges for a particular year, the Compensation Committee
relies on consultant surveys regarding salaries and other short-term
compensation at comparable companies. In making salary adjustments, the
Compensation Committee also makes subjective determinations regarding the
performance of individual officers.
 
  Incentive Bonus Plan
 
     Under the plan, the Compensation Committee establishes bonuses based on
budgeted goals set at the outset of the year relating to net income and diluted
earnings per share as adjusted for extraordinary items and one time charges. In
the early part of each fiscal year, the Compensation Committee establishes
minimum and maximum bonuses with a sliding scale based on achievement of
financial results for such year. For fiscal 1998, the plan provided for awards
ranging from 10% to 140% of year-end salary based upon the Company's financial
performance, with the Compensation Committee having discretion to award a higher
amount under special circumstances.
 
  Stock Option Plan
 
     Through fiscal 1998, Mr. Jenkins and Mr. Bazlen did not participate in any
of our stock option plans. Stock option grants had been made to these
individuals pursuant to separate agreements governing the relevant grant. At the
end of fiscal 1998, including prior grants, Mr. Jenkins had options for 658,542
shares of common stock, 100,491 of which had vested and Mr. Bazlen had options
for 299,337 shares of common stock, of which 106,905 had vested.
 
     During fiscal 1998, our Vice Presidents and Senior Vice Presidents were
eligible to participate in our 1996 Executive Stock Option Plan. As of January
31, 1999, we had granted options to purchase 390,908 shares under the Executive
Plan, with exercise prices ranging from $12.04 to $28.13 per share. A portion of
all options granted under the Executive Plan prior to the end of fiscal 1998
were subject to performance vesting based on our operating results during the
first four years of the option term. Our remaining employees are
                                        9
<PAGE>   12
 
eligible to participate in our 1996 Associate Stock Option Plan. As of January
31, 1999, we had granted options to purchase 796,416 shares under the Associate
Plan, with exercise prices ranging from $12.04 to $30.66 per share.
 
  Retirement Plan
 
     The Company sponsors 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. 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. The Company has historically elected to match a portion
of a participant's contributions to this plan.
 
CEO AND PRESIDENT COMPENSATION
 
  Base Salary and Incentive Bonus
 
     The Company has employment agreements with each of Messrs. Jenkins and
Bazlen. Pursuant to Mr. Jenkins' employment agreement, the Company paid Mr.
Jenkins an annual base salary of $600,000 for fiscal 1998 and a bonus of
$840,000. Pursuant to Mr. Bazlen's employment agreement, the Company paid Mr.
Bazlen an annual base salary of $450,000 and a bonus of $630,000 for fiscal
1998. The bonus amounts paid to these senior executives are tied to the
Company's financial performance. In fiscal 1998, the Company's earnings per
share, excluding one-time charges, exceeded targets established by the
Compensation Committee during the first quarter of fiscal 1998, which entitled
these senior executives to annual bonuses equal to 140% of their base salaries
for the fiscal year.
 
  Stock Options
 
     In connection with the successful completion of our initial public offering
in March 1998, Mr. Jenkins was granted an option for 216,635 shares of our
common stock. During fiscal 1998, Mr. Bazlen was not granted any additional
options to purchase our common stock.
 
  Compliance with Section 162(m) of the Internal Revenue Code
 
     Section 162(m) of the Internal Revenue Code of 1986, as amended, generally
disallows a federal income tax deduction to public companies to the extent that
compensation paid to the corporation's chief executive officer and each of the
four other most highly compensated officers in any single fiscal year exceeds $1
million. Certain compensation, including "performance-based" compensation
meeting the requirements of Section 162(m), is excluded from the determination
as to whether the $1 million threshold has been reached with respect to a
particular employee. As Section 162(m) requires the Compensation Committee to be
comprised of "outside" directors, Jules Trump and Eddie Trump, former officers
of the Company or its affiliates, have agreed to resign from the Compensation
Committee and Robert Smith has agreed to join the Compensation Committee.
Beginning in fiscal 1999, the Compensation Committee also intends to comply with
the requirements of Section 162(m) with respect to the Company's incentive bonus
plan for Messrs. Jenkins and Bazlen and with respect to the Company's stock and
option plans generally.
 
                                          RESPECTFULLY SUBMITTED,

EMPLOYMENT AGREEMENTS
 
     We have employment agreements with each of Messrs. Jenkins and Bazlen.
Pursuant to his employment agreement, we paid Mr. Jenkins an annual base salary
of $600,000 for fiscal 1998 and a bonus of $840,000. Mr. Jenkins' annual bonus
is awarded based upon the financial performance and operating results of the
Company with reference to goals established by the Compensation Committee of the
Board of Directors during the first quarter of any fiscal year. The Compensation
Committee has broad discretion in determining the measures upon which Mr.
Jenkins' bonus will be based, but in the past has used criteria such as net
income and earnings per share. Based on Mr. Jenkins' annual review required by
his employment agreement, the Compensation Committee increased Mr. Jenkins'
annual base salary for fiscal 1999 to $650,000.
 
                                       13
<PAGE>   16
 
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 $450,000 and a bonus of $630,000 for 1998. Mr. Bazlen's annual bonus
is awarded based upon the financial performance and operating results of the
Company with reference to goals established by the Compensation Committee of the
Board of Directors during the first quarter of any fiscal year. The Compensation
Committee has broad discretion in determining the measures upon which Mr.
Bazlen's bonus will be based, but in the past has used criteria such as net
income and earnings per share. Based on Mr. Bazlen's annual review required by
his employment agreement, the Compensation Committee increased Mr. Bazlen's
annual base salary for fiscal 1999 to $485,000. 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 his employment 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). The Investcorp Group and the
       Company accelerated the vesting of these shares to permit their sale in a
       registered public offering in December 1998.
 
     - 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
       mentioned above. Mr. Jenkins repaid the loan with the proceeds he
       received from the sale of the shares purchased from the Investcorp Group.
 
     - 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."
 
  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. This option has vested to the extent of
200,982 shares. As a result of vesting acceleration triggered by our initial
public offering, 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 acquisition of 82 stores from Trak Auto Corporation
in December 1997, we granted Mr. Jenkins an option to purchase 39,940 shares of
our common stock, exercisable at $12.04 per share. In April 1999, this option
vested to the extent of 9,989 shares. The remainder of this option will vest in
equal annual installments in April of the next three years.
 
     In connection with our initial public offering, we granted Mr. Jenkins an
option to purchase 216,635 shares of our common stock, exercisable at $20.00 per
share. This option will vest 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 vested to the extent of 171,048 shares. As
a result of vesting acceleration triggered by our initial public offering, the
 
                                       14
<PAGE>   17
 
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 March 1999, we granted Messrs. Jenkins and Bazlen stock options pursuant
to our 1996 Executive Stock Option Plan. We granted Mr. Jenkins an option to
purchase 72,000 shares of common stock, and we granted Mr. Bazlen an option to
purchase 51,000 shares of common stock. The exercise price for these options is
$32.25 per share. These options will become exercisable in three equal
installments, beginning on December 31, 1999 and on each of the following two
anniversaries thereof, assuming the executive's employment continues during this
period.
 
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.
 
  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 January 31, 1999, we had granted options
to purchase 796,416 shares under the Associate Plan, with exercise prices
ranging from of $12.04 to $30.66 per share.
 
     Options granted under the Associate Plan through the end of Fiscal 1998
vest and become exercisable in three equal installments on the second, third,
and fourth anniversaries of the date of their grant, assuming the associates'
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 to one person or a group of related persons, the unvested portion of any
option automatically vests.
 
     In March 1999, we granted our associates options to purchase up to an
aggregate of 177,650 shares under the Associate Plan, exercisable at $32.25 per
share. These options will become exercisable in three equal installments,
beginning on December 31, 1999 and on each of the following two anniversaries
thereof, assuming the associate's employment continues during this period
("Three Year Vesting"). The other terms of these options are identical to the
options granted under the Associate Plan prior to the end of fiscal 1998.
 
  The 1996 Executive Stock Option Plan
 
     During fiscal 1998, Vice Presidents and Senior Vice Presidents were
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 January 31, 1999, we had granted options to purchase
390,908 shares under the Executive Plan, with exercise prices ranging from
$12.04 to $28.13 per share.
 
     The options granted under the Executive Plan through the end of fiscal 1998
are subject to 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 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
 
                                       15
<PAGE>   18
 
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 common stock to one
person or a group of related persons, the unvested portion of any option
automatically vests.
 
     In March 1999, we granted our executives options to purchase up to an
aggregate of 145,400 shares under the Executive Plan (excluding the 123,000
options granted to Messrs. Jenkins and Bazlen), exercisable at $32.25 per share.
These options are entirely subject to Three Year Vesting. No portion of these
options is subject to performance vesting or is eligible for a performance
bonus. The other terms of these options are identical to the options granted
under the Executive Plan prior to the end of fiscal 1998.
 
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. No purchases
have been made since 1997. If a participant used more borrowed money than cash
to purchase his or her shares, he or she was required to reduce the principal
balance of the loan using 50% of the after-tax portion of his 1998 annual bonus,
which was paid in April 1999, to an amount equal to the amount of cash he or she
used to purchase shares, if any. Each loan participant entered into an agreement
pledging his or her 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 our senior credit facility. 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.

                            STOCK PERFORMANCE GRAPH
 
     The following graph compares the cumulative total stockholder return on our
common stock to the cumulative total stockholder return on shares of companies
in (1) the Standard & Poor's 500 Index, and (2) the Standard & Poor's Midcap
Retail Specialty Index. The Standard & Poor Midcap Retail Specialty consists of
Abercrombie and Fitch, Barnes & Noble, Bed Bath & Beyond, Best Buy Co Inc., BJ's
Wholesale, Borders Group, Claire's Stores, CompUSA Inc., Fastenal Co., General
Nutrition Co., Heilig-Meyers Co., Officemax Inc., Payless Shoesource, Saks Inc.,
Tech Data Corp., and Tiffany & Co.
 
     The period covered is from March 12, 1998 (the first day our common stock
was traded on the New York Stock Exchange) through January 31, 1999 (the last
day of fiscal 1998). The graph assumes that $100 was invested on March 12, 1998
in our common stock and in each comparison index, and assumes that any dividends
paid were reinvested. The comparisons in the graph are required by the
Securities and Exchange Commission and are not intended to forecast or be
indicative of possible future performance of our common stock.

(1) The Investcorp Group, as defined in the stockholders' agreement, owns
    6,030,964 shares, or 21.7% of our outstanding common stock. The Carmel
    Group, as defined in the stockholders' agreement, owns 5,901,824 shares, or
    21.3% of our outstanding common stock. 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

    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 "Certain Relationships and Related Transactions -- Stockholders'
    Agreement." Because we believe that our presentation more accurately
    reflects ownership of the Company's common 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.

    entities or their stockholders or principals have entered into revocable
    management services or similar agreements with an affiliate of Investcorp
    pursuant to which each of such entities or their stockholders or principals

    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

                      RATIFICATION OF INDEPENDENT AUDITOR
 
     The Board of Directors has appointed PricewaterhouseCoopers LLP ("PwC") as
our independent auditor for fiscal 1999. The stockholders are requested to
ratify this appointment. The appointment of PwC as our independent auditor will
be deemed to be ratified upon approval by a majority of the issued and
outstanding shares of the Company entitled to vote at the Annual Meeting.
 
     PwC has been our independent auditor since December 1996, and no
relationship exists other than the relationship between independent public
accountant and client.
 
     If the appointment of PwC as independent auditor for fiscal 1999 is not
ratified by the stockholders, the Board of Directors will consider other
auditors for our next fiscal year. However, because of the difficulty in making
any substitution of auditor for the current year, the appointment of PwC for
fiscal 1999 will stand, unless the Board of Directors finds other reason for
making a change.
 
     A representative of PwC will be available at the Annual Meeting to respond
to appropriate questions from stockholders.
 
     THE AFFIRMATIVE VOTE OF THE HOLDERS OF A MAJORITY OF SHARES OF COMMON STOCK
ISSUED AND OUTSTANDING IS REQUIRED TO RATIFY THE APPOINTMENT OF PWC AS OUR
INDEPENDENT AUDITOR.
 
     YOUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE RATIFICATION
OF PRICEWATERHOUSECOOPERS LLP AS INDEPENDENT AUDITOR FOR FISCAL 1999, WHICH IS
DESIGNATED AS PROPOSAL 2 ON THE ENCLOSED PROXY CARD.

                                  ADOPTION OF
                            THE CSK AUTO CORPORATION
                              DIRECTORS STOCK PLAN
 
     The summary of the main features of the Directors Stock Plan is qualified
in its entirety by the complete text of the plan which is set out as Appendix A
to this Proxy Statement.
 
THE DIRECTORS STOCK PLAN
 
     On June 12, 1998, the Board of Directors adopted, subject to the approval
of our stockholders, the CSK Auto Corporation Directors Stock Plan (the
"Directors Plan"). The Directors Plan will become effective only upon approval
by a majority of the issued and outstanding shares of the Company entitled to
vote at the Annual Meeting. Assuming that our stockholders approve the Directors
Plan, the Company will be able to make stock-based awards of up to an aggregate
of 50,000 shares of common stock. These awards may be in the form of restricted
stock, stock options or stock appreciation rights.
 
  Purpose
 
     The purpose of the Directors Stock Plan is to advance the interests of CSK
Auto Corporation, by enabling the Company to attract, retain and motivate
qualified individuals to serve on the Company's Board of Directors and to align
the financial interests of such individuals with those of the Company's
stockholders by providing for or increasing their proprietary interest in the
Company.
 
  Eligibility
 
     All of our non-employee directors will be eligible to participate in the
Directors Plan. Of our thirteen current board members, eleven are non-employee
directors.
 
  Terms
 
     The Board of Directors may issue up to a maximum of 50,000 shares of common
stock under the Directors Plan. The maximum number of shares for which options
may be issued in any one year to any one person is 50,000. If there is any
reclassification, exchange or conversion of our common stock into another class
of capital stock, or a stock split, reverse split, stock dividend, spin-off or
other similar transaction, the maximum shares of common stock otherwise
available for issuance under the Directors Plan will be appropriately adjusted.
Awards under the Directors Plan may consist of stock options, restricted stock,
stock appreciation rights, or any other arrangement which involves the issuance
of our common stock or of an interest which has a value based upon the value of
our common stock. No stock options or restricted stock may be awarded after the
tenth anniversary of the date the Directors Plan is approved by the Company's
stockholders, subject to the right of the Board of Directors to terminate the
Directors Plan at any time prior.
 
     The Board of Directors may issue options to purchase shares of common stock
of the Company at the exercise price set forth in the option agreement relating
to the grant. The exercise price for each stock option shall be established by
the Board or under a formula established by the Board. The Board also has the
discretion to determine the schedule of vesting, the terms of expiration, the
number of shares subject to an option and such other terms and conditions of
options as do not conflict with the terms of the Directors Plan.
 
     The Board of Directors may award shares of common stock under the Plan.
These awards may be subject to such conditions, restrictions or other vesting
terms as established in the sole discretion of the Board. The conditions,
restrictions or vesting terms may be contingent upon the passage of time,
continued service or achievement of Company or individual performance goals, as
specified by the Board.
 
     The Board of Directors may award stock appreciation rights or other stock
based awards evidenced by "Stock Units." A "Stock Unit" is a bookkeeping entry
representing an amount equal to the fair market value of one share of common
stock. Vesting of the Stock Units may be deferred or conditioned upon criteria
 
                                       21
<PAGE>   24
 
determined by the Board of Directors. Settlement of the Stock Units upon vesting
may be made in cash, in shares of common stock, or in another medium as provided
by the Board of Directors. The amount of such settlement may be increased by an
interest factor or dividend equivalents.
 
  Outside Directors Compensation Policy
 
     In order to ensure consistent application of the Directors Plan, in October
1998 our Board of Directors adopted an outside director compensation policy. As
this policy does not currently apply to directors associated with the Investcorp
Group or the Carmel Group, only two directors are currently compensated under
this policy. This policy provides that participants must receive at least
$10,000 of their annual $25,000 stipend in the form of restricted stock grants
pursuant to the Directors Plan. The annual stipend is pro-rated from the time of
the director's election to the proposed date for our next annual meeting of
stockholders. Awards of restricted stock are valued at fair market value at the
close of business on the date immediately prior to the date of the grant. As of
April 30, 1999, we have granted 1,516 shares of restricted common stock under
the Directors Plan. These grants are contingent on stockholder approval of the
Directors Plan and, if such approval is not obtained, shall be of no effect. The
Board of Directors may change its outside director compensation policy in its
sole discretion, without the approval of our stockholders.
 
  Administration
 
     The Directors Plan is administered by the Board (the "Administrator"),
except that as provided therein the Plan may be administered by a committee of
the Board, as appointed from time to time by the Board. The Board has appointed
the Compensation Committee to administer the Directors Plan. The Directors Plan
authorizes the Administrator to prescribe, amend and rescind rules relating to
this Plan or take actions as deemed appropriate to implement or interpret the
provisions of the Directors Plan. The Board of Directors may amend the Directors
Plan at any time as determined appropriate, without further action of the
stockholders except as required by law; provided, however, that no change in any
option granted may be made that would impair the rights of the optionee without
the consent of such optionee. Notwithstanding the foregoing, the Directors Plan
cannot be amended to increase the total number of shares issuable thereunder
without the approval of our stockholders.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     A non-employee Director who is granted a stock option pursuant to the
Directors Plan generally will recognize no taxable income at the time of the
grant, but generally will recognize taxable income upon the exercise of the
stock option. The amount of income recognized by the director upon the exercise
of the stock option will be measured by the excess, if any, of the fair market
value of the shares of common stock acquired at the time of exercise over the
exercise price paid therefor. The Company will generally be entitled to a
deduction corresponding to the amount of income recognized by the non-employee
director.
 
     In general, a non-employee director who receives a grant of common stock
that is subject to restrictions that impose a substantial risk of forfeiture
will not recognize income upon the receipt of such shares. However, upon the
lapse of the restrictions to which such stock is subject, the non-employee
director will recognize compensation income, and receive a basis in such shares,
in an amount equal to the fair market value of the vested shares determined on
the vesting date. The Company will be entitled to a compensation deduction equal
to such amount. Alternatively, if the non-employee director makes an election
under Section 83(b) of the Internal Revenue Code of 1986, as amended (the
"Code"), no later than 30 days after a stock grant, or if the stock is not
subject to a substantial risk of forfeiture upon grant, the non-employee
director will recognize compensation income in the taxable year of the stock
grant and receive a basis equal to the fair market value of such shares
determined on the date of grant, and the Company will be entitled to a
compensation deduction equal to such amount.
 
     Unless a non-employee director makes an election under Code Section 83(b),
as described above, amounts paid to the non-employee director as dividends with
respect to such shares prior to the vesting date will be treated for federal
income tax purposes as compensation income taxable at ordinary income tax rates
 
                                       22
<PAGE>   25
 
for which the Company will be entitled to a compensation deduction with respect
to such amounts. However, upon the vesting of the Non-Employee Director's
shares, or if the Non-Employee Director makes a timely Code Section 83(b)
election prior to such vesting, amounts paid to the Non-Employee Director as
dividends will be treated as dividends for federal income tax purposes for which
the Company will not be entitled to a deduction with respect to such amounts.
 
     The foregoing does not purport to be a complete summary of the Federal
income tax considerations relevant to stock awards granted under the Directors
Plan. In addition, the tax consequences under state, local or foreign law may
differ from the consequences under Federal income tax law.

     The summary of the main features of the amended and restated CSK Auto
Corporation 1996 Executive Stock Option Plan is qualified in its entirety by the
complete text of the plan which is set out as Appendix B to this Proxy
Statement.
 
AMENDED AND RESTATED 1996 EXECUTIVE STOCK OPTION PLAN
 
     On April 30, 1999, the Board of Directors adopted, subject to the approval
of our stockholders, an amendment and restatement of the CSK Auto Corporation
1996 Executive Stock Option Plan (the "Executive Plan"). This amendment and
restatement will become effective only upon approval by a majority of the issued
and outstanding shares of the Company entitled to vote at the Annual Meeting.
 
  Purpose
 
     The purpose of the Executive Plan is to advance the interests of CSK Auto
Corporation, by enabling the Company to attract, retain and motivate qualified
individuals to serve as the Company's senior management and to align the
financial interests of such individuals with those of the Company's stockholders
by providing for or increasing their proprietary interest in the Company.
 
     As of April 30, 1999, options for 677,279 shares, out of a maximum number
of 684,200 shares of common stock permitted to be granted under the terms of the
Executive Plan, have been granted by the Board of Directors. Certain of the
options previously granted under the Executive Plan may require the issuance of
additional options in the event of superior financial performance by the
Company. Although the performance options that must be issued in respect of
fiscal 1998 have been awarded, the Board of Directors may need to issue options
for additional shares of common stock under the Executive Plan in respect of
future fiscal years. This amendment and restatement of the Executive Plan will
increase the maximum number of shares for which options may be granted by
60,000, to a total of 744,200 shares of common stock, which will allow us to
grant future options in accordance with potential future obligations under the
Executive Plan. There are no other material changes to the Executive Plan made
by this amendment and restatement.
 
     The Board of Directors intends to make all other future option grants under
the 1999 Employee Stock Option Plan, if it is approved by our stockholders. The
approval of the 1999 Employee Stock Option Plan is the subject of Proposal 6 of
this Proxy Statement.
 
  Terms
 
     The Board of Directors may issue up to a maximum of 744,200 shares of
common stock under the amended and restated Executive Plan. The maximum number
of shares for which options may be issued in any one year to any one person is
684,200. If there is any reclassification, exchange or conversion of our common
stock into another class of capital stock, or a stock split, reverse split,
stock dividend, spin-off or other similar transaction, the maximum shares of
common stock otherwise available for issuance under the Executive Plan will be
appropriately adjusted. Awards under the Executive Plan consist of stock
options, which may be incentive stock options ("ISOs") intended to qualify under
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), and
non-qualified stock options which do not qualify as ISOs ("NQSOs"). No stock
options may be awarded after October 30, 2006, subject to the right of the Board
of Directors to terminate the Executive Plan at any time prior.
 
     The Board of Directors may issue options to purchase shares of common stock
of the Company at the exercise price set forth in the option agreement relating
to the grant. The exercise price for each stock option shall be established by
the Board or under a formula established by the Board. The Board may also
determine
 
                                       24
<PAGE>   27
 
in its sole discretion the schedule of vesting, the terms of expiration, the
number of shares subject to an option and such other terms and conditions of
options as do not conflict with the terms of the Executive Plan.
 
     The Board of Directors intends to limit its future grants of options under
the Executive Plan to grants in satisfaction of its potential future obligations
under previously granted options. The terms of these previously granted options
provide that, in the event that certain performance goals with respect to the
first four full fiscal years during an option's term are exceeded by at least
10%, then the executive will automatically receive an additional option to
purchase shares of common stock equal to up to 5% (20% on a cumulative basis) of
his or her original option grant. The exercise price of the shares of common
stock under each additional option shall be equal to the fair market value of
the common stock on the grant date of the original option. The approval of the
terms of issuance of these additional options is the subject of Proposal 5 of
this Proxy Statement.
 
  Eligibility
 
     Eligibility for participation in the Executive Plan is subject to the
discretion of the Board of Directors. Historically, our Vice Presidents, Senior
Vice Presidents and more senior executives have been eligible for participation.
 
     If our stockholders approve the amended and restated Executive Plan, the
Board of Directors intends to limit future participation to those prior
participants to whom the Company may have future obligations resulting from
prior option grants until all such obligations are satisfied.
 
  Administration
 
     The Executive Plan is administered by the Board (the "Administrator"),
except that as provided herein the Plan may be administered by a committee of
the Board, as appointed from time to time by the Board. The Board has appointed
the Compensation Committee to administer the Executive Plan. The Executive Plan
authorizes the Administrator to prescribe, amend and rescind rules relating to
this Plan or take actions as deemed appropriate to implement or interpret the
provisions of the Executive Plan. The Board of Directors may amend the Executive
Plan at any time as determined appropriate, without further action of the
stockholders except as required by law; provided, however, that no change in any
option granted may be made that would impair the rights of the optionee without
the consent of such optionee. Notwithstanding the foregoing, the Executive Plan
cannot be amended to increase the total number of shares issuable thereunder
without the approval of our stockholders.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     An executive that receives a stock option qualifying as an ISO pursuant to
the Executive Plan will recognize no taxable income upon the grant of such
option. Further, provided certain requirements are complied with, such executive
will not recognize taxable income upon the exercise of such option and the
receipt of the common stock subject to such option. Provided the requirements
for an ISO are complied with, the Company will not be entitled to a compensation
deduction with respect to the issuance or exercise of an ISO to a participating
executive.
 
     An executive who is granted an NQSO pursuant to the Executive Plan
generally will recognize no taxable income at the time of the grant of such
option, but generally will recognize taxable income upon the exercise of such
option. The amount of income recognized upon the exercise of the stock option
will be measured by the excess, if any, of the fair market value of the shares
of common stock subject to such option at the time of exercise over the exercise
price paid therefor. The Company will generally be entitled to a compensation
deduction corresponding to the amount of income recognized by the executive.
 
     The foregoing does not purport to be a complete summary of the Federal
income tax considerations relevant to stock options granted under the Executive
Plan. In addition, the tax consequences under state, local or foreign law may
differ from the consequences under Federal income tax law.

                        1996 EXECUTIVE STOCK OPTION PLAN
 
     The summary of the main features of certain options ("Bonus Options")
issuable pursuant to the amended and restated CSK Auto Corporation 1996
Executive Stock Option Plan is qualified in its entirety by the complete text of
the plan which is set out as Appendix B to this Proxy Statement.
 
BONUS OPTIONS UNDER AMENDED AND RESTATED 1996 EXECUTIVE STOCK OPTION PLAN
 
  Purpose
 
     The purpose of issuing Bonus Options pursuant to the amended and restated
1996 Executive Stock Option Plan is to advance the interests of CSK Auto
Corporation, by enabling the Company to attract, retain and motivate qualified
individuals to serve as the Company's senior management and to align the
financial interests of such individuals with those of the Company's stockholders
by providing for or increasing their proprietary interest in the Company.
 
  Terms of Bonus Options Issued Under Plan
 
     The Compensation Committee (the "Committee") of the Board of Directors
intends to issue future Bonus Options in satisfaction of its potential future
obligations under options previously granted under the Executive Plan. The terms
of these previously granted options ("Base Options") provide that, in the event
that certain performance goals, which are based upon the Company's earnings
before interest, taxes, depreciation and amortization or "EBITDA" with respect
to the first four full fiscal years during an option's term, are exceeded by at
least 10%, then the executive will automatically receive Bonus Options for
shares in an amount equal to up to 5% (20% on a cumulative basis) of the shares
available under his or her Base Option grant. The exercise price of the shares
of common stock under each Bonus Option shall be equal to the fair market value
of the common stock on the grant date of the Base Option in respect of which it
is granted, which exercise price may be below the fair market value of the
subject shares of common stock on the grant date of the Bonus Option.
 
     The following chart sets forth the exercise prices at which Bonus Options
could be granted under the Executive Plan and the maximum number of shares of
common stock for which Bonus Options may be granted to any person at each such
price during any one year.
 
<TABLE>
<CAPTION>
EXERCISE       MAXIMUM
PRICE PER     NUMBER OF
SHARE($)    BONUS OPTIONS
- ---------   -------------
<S>         <C>
  12.04         2,682
  20.00           170
  25.50         1,700
  25.78           170
  28.13         2,500
  29.44           340
</TABLE>
 
     The actual amount of Bonus Options that may be granted to any participating
executive in any one year and the strike price(s) at which such Bonus Options
may be granted will depend upon the amount of Base Options originally granted to
such executive and the exercise price of such Base Options. Some participating
executives received more than one grant of Base Options, with different exercise
prices, and thus may be entitled to receive Bonus Options with different
exercise prices. No participating executive will be entitled to
 
                                       27
<PAGE>   30
 
receive more than the maximum number of Bonus Options set forth above with
respect to each exercise price set forth above in any one year.
 
  Eligibility
 
     If our stockholders approve the amendment restatement of the Executive Plan
as described in Proposal 4, the Board of Directors intends to issue Bonus
Options to the persons eligible therefor until all such Bonus Options are
issued. The class of persons that will be eligible to receive Bonus Options
under the Executive Plan following the adoption of the amended and restated
Executive Plan accordingly will consist of those of our employees who served as
Senior Vice Presidents or Vice Presidents between October 30, 1996 and January
30, 1999.
 
  Administration
 
     All Bonus Options to be granted under the Plan will be granted by the
Compensation Committee of the Board of Directors. The Compensation Committee
will not have the authority to increase the total number of shares for which
Bonus Options may be issued to any individual participant in the Executive Plan,
nor to decrease the exercise price at which such Bonus Options could be issued
as described above.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     Section 162(m) of the Code generally disallows a federal income tax
deduction to public companies to the extent that compensation paid to the
company's chief executive officer and each of the company's four other most
highly compensated officers in any single fiscal year exceeds $1 million.
Certain compensation, including "performance-based" compensation meeting the
requirements of Section 162(m), is excluded from the determination as to whether
the $1 million threshold has been reached with respect to a particular employee.
For compensation to constitute "performance-based" compensation, such
compensation must be conditioned upon the attainment of one or more "performance
goals." As noted above, the Bonus Options will be granted based on the
achievement of certain targets relating to the EBITDA of the Company during the
first four years that previously-granted Base Options are outstanding. To
satisfy the requirements that apply to performance-based compensation, the
material terms of the "performance goals" that are set forth above must be
approved by the Company's stockholders.
 
     Assuming that our stockholders approve the terms of issuing Bonus Options
under the amended and restated 1996 Executive Stock Option Plan as described
above, compensation attributable to Bonus Options issued under the Plan will
qualify as "performance-based compensation" that is exempt from the $1 million
deduction limit imposed by Section 162(m).
 
     The foregoing does not purport to be a complete summary of the Federal
income tax considerations relevant to stock options granted under the Executive
Plan. In addition, the tax consequences under state, local or foreign law may
differ from the consequences under Federal income tax law.

                            THE CSK AUTO CORPORATION
                        1999 EMPLOYEE STOCK OPTION PLAN
 
     The summary of the main features of the 1999 Employee Stock Option Plan is
qualified in its entirety by the complete text of the plan which is set out as
Appendix C to this Proxy Statement.
 
1999 EMPLOYEE STOCK OPTION PLAN
 
     On April 30, 1999, the Board of Directors adopted, subject to the approval
of our stockholders, the CSK Auto Corporation 1999 Employee Stock Option Plan
(the "Employee Plan"). The Employee Plan will become effective only upon
approval by a majority of the outstanding shares of the Company entitled to vote
at the Annual Meeting. Assuming that our stockholders approve the Employee Plan,
the Company will be able to make stock option awards of up to an aggregate of
750,000 shares of common stock. These awards may be incentive stock options
("ISOs") intended to qualify under Section 422 of the Internal Revenue Code of
1986, as amended (the "Code") or non-qualified stock options which do not
qualify as ISOs ("NQSOs").
 
  Purpose
 
     The purpose of the Employee Plan is to advance the interests of CSK Auto
Corporation, by enabling the Company to attract, retain and motivate qualified
individuals to serve as employees of the Company and to align the financial
interests of such individuals with those of the Company's stockholders by
providing for or increasing their proprietary interest in the Company.
 
  Eligibility
 
     Eligibility for participation in the Employee Plan is subject to the
discretion of the Board of Directors. The Board of Directors intends to allow
all of the Company's salaried employees to participate in the Employee Plan.
 
  Terms
 
     The Board of Directors may issue up to a maximum of 750,000 shares of
common stock under the Employee Plan. The maximum number of shares for which
options may be issued in any one year to any one person is 150,000, provided,
however, that in the case of an employee hired by the Company within a fiscal
year, the maximum number of shares for which options may be issued to such new
employee in such fiscal year will be 250,000. In no circumstances will any
person be entitled to receive options to acquire more than 250,000 shares of
common stock under the Employee Plan in any one fiscal year. If there is any
reclassification, exchange or conversion of our common stock into another class
of capital stock, or a stock split, reverse split, stock dividend, spin-off or
other similar transaction, the maximum shares of common stock otherwise
available for issuance under the Employee Plan will be appropriately adjusted.
Awards under the Executive Plan consist of stock options, which may be ISOs or
NQSOs. No stock options or restricted stock may be awarded after the tenth
anniversary of the date the Employee Plan is approved by the Company's
stockholders, subject to the right of the Board of Directors to terminate the
Employee Plan at any time prior.
 
     The Board of Directors may issue options to purchase shares of common stock
of the Company at the exercise price set forth in the option agreement relating
to the grant. The exercise price for each stock option shall be established by
the Board or under a formula established by the Board. The Board may also
determine in its sole discretion the schedule of vesting, the terms of
expiration, the number of shares subject to an option and such other terms and
conditions of options as do not conflict with the terms of the Employee Plan.
 
  Administration
 
     The Employee Plan is administered by the Board (the "Administrator"),
except that as provided herein the Employee Plan may be administered by a
Committee of the Board, as appointed from time to time by the
                                       29
<PAGE>   32
 
Board. The Board has appointed the Compensation Committee to administer the
Employee Plan. The Employee Plan authorizes the Administrator to prescribe,
amend and rescind rules relating to this Plan or take actions as deemed
appropriate to implement or interpret the provisions of the Employee Plan. The
Board of Directors may amend the Employee Plan at any time as determined
appropriate, without further action of the stockholders except as required by
law; provided, however, that no change in any option granted may be made that
would impair the rights of the optionee without the consent of such optionee.
Notwithstanding the foregoing, the Employee Plan cannot be amended to increase
the total number of shares issuable thereunder or change the eligibility
requirements of the Employee Plan without the approval of our stockholders.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     An employee that receives a stock option qualifying as an ISO pursuant to
the Employee Plan will recognize no taxable income upon the grant of such
option. Further, provided certain requirements are complied with, such employee
will not recognize taxable income upon the exercise of such option and the
receipt of the common stock subject to such option. Provided the requirements
for an ISO are complied with, the Company will not be entitled to a compensation
deduction with respect to the issuance of an ISO to, or the exercise of an ISO
by, a participating employee.
 
     An employee who is granted an NQSO pursuant to the Employee Plan will
recognize no taxable income at the time of the grant, but generally will
recognize taxable income upon the exercise of the option. The amount of income
recognized upon the exercise of such option will be measured by the excess, if
any, of the fair market value of the shares of common stock subject to the
option at the time of exercise over the exercise price paid therefor. The
Company will generally be entitled to a compensation deduction corresponding to
the amount of income recognized by the employee.
 
     The foregoing does not purport to be a complete summary of the Federal
income tax considerations relevant to stock awards granted under the Employee
Plan. In addition, the tax consequences under state, local or foreign law may
differ from the consequences under Federal income tax law.

1999 EXECUTIVE INCENTIVE PROGRAM
 
     On April 30, 1999, the Compensation Committee of the Board of Directors
adopted, subject to the approval of our stockholders, the terms for certain
annual incentive bonuses to be paid to Maynard Jenkins and James Bazlen pursuant
to the terms of their respective employment agreements (the "Incentive
Program"). The Incentive Program will become effective only upon approval by a
majority of the outstanding shares of the Company entitled to vote at the Annual
Meeting.
 
  Purpose
 
     Pursuant to the terms of their respective employment agreements, Messrs.
Jenkins and Bazlen are entitled to annual cash incentive bonuses in an amount
equal to a percentage of their respective annual base salaries determined with
reference to financial targets established by the Compensation Committee. In
order to qualify these annual cash incentive bonuses for favorable tax treatment
under Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code"), the Board of Directors has established the Incentive Program and is
submitting it to our stockholders for their approval.
 
  Eligibility
 
     Only Messrs. Jenkins and Bazlen are eligible for participation in the
Incentive Program.
 
  Terms
 
     Under the Incentive Program, the Compensation Committee may grant cash
incentive bonuses to Messrs. Jenkins and Bazlen if the performance goals
established by the Committee for fiscal 1999 are achieved. The bonuses to be
paid to Messrs. Jenkins and Bazlen for fiscal 1999 will be based on the net
income or earnings per share of the Company, or a combination thereof.
 
     In fiscal 1999, Mr. Jenkins may not be awarded an annual incentive bonus
under the Incentive Program in excess of $910,000. In fiscal 1999, Mr. Bazlen
may not be awarded an annual incentive bonus under the Incentive Program in
excess of $679,000. These maximum amounts are limitations and do not represent
targets.
 
     The Committee may adjust these cash incentive bonuses for individual
performance on the basis of such quantitative and qualitative performance
measure and evaluations as it deems appropriate; provided, however, that to the
extent required by the requirements applicable to performance-based
compensation, no bonus may be increased in excess of the limitations set forth
above.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     Section 162(m) of the Code generally disallows a federal income tax
deduction to public companies to the extent that compensation paid to the
company's chief executive officer and each of the company's four other most
highly compensated officers in any single fiscal year exceeds $1 million.
Certain compensation, including "performance-based" compensation meeting the
requirements of Section 162(m), is excluded from the determination as to whether
the $1 million threshold has been reached with respect to a particular employee.
For compensation to constitute "performance-based" compensation, such
compensation must be conditioned upon the attainment of one or more "performance
goals." To satisfy the requirements that apply to performance-based
compensation, the material terms of the "performance goals" that are set forth
above must be approved by the Company's stockholders, and approval of the
Incentive Program will also constitute approval of the foregoing terms.

     Assuming that our stockholders approve the Incentive Program, incentive
payments made under the Program will qualify as "performance-based compensation"
that is exempt from the $1 million deduction limit imposed by Section 162(m).

STOCKHOLDER PROPOSALS
 
     Our By-Laws and Securities and Exchange Commission regulations permit
stockholders to submit proposals for consideration at annual meetings of
stockholders. Any such proposals for the Annual Meeting must be received by May
22, 1999 in order to be deemed timely raised for action at the Annual Meeting.
The advance notice provisions of the Company's By-Laws require that any proposal
or nomination for the Company's Annual Meeting to be held in 2000 must be
submitted in writing to the Secretary of the Company not less than 90 days nor
more than 120 days prior to the anniversary of this year's Annual Meeting. In
order for any proposal to be included in proxy materials relating to the
Company's Annual Meeting to be held in 2000, such proposals must be submitted to
the Company on or before January 13, 2000, and must comply with our By-Laws and

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's executive officers and directors, and persons who own more than
10% of the Company's common stock, to file reports of ownership and changes in
ownership with the Securities and Exchange Commission and the New York Stock
Exchange, and to furnish the Company with copies of these filings. Based solely
on our review of the copies of such forms that we received, we believe that each
of Mr. Antioco and Larry Buresh filed his initial Form 3 non-timely, Dale Ward
filed one Form 4 non-timely to report two transactions, Mr. Jenkins filed one
Form 5 non-timely to report two transactions, and each of Auto Equity Limited,

to align the financial interests of such individuals with those of the Company's
stockholders by providing for or increasing their proprietary interest in the
Company. The stock options granted pursuant to this Plan are not qualified under
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code").

                          NON-EMPLOYEE DIRECTOR AWARDS
 
     The Board may provide for stock options and/or stock grants to be awarded
to Non-Employee Directors in consideration for their service to the Company. The
Board shall determine to which Non-Employee Directors any such stock options
and/or stock grants shall be awarded hereunder (any such person, a
"Participant"). The Board shall specify the number of shares subject to each
stock option or stock grant provided for under this Section 5, or the formula
pursuant to which such number shall be determined, the Participants to receive
any such award, the date of award and the vesting and expiration terms
applicable to such stock option or stock grant. The award of stock options or

retainer or other fees, shall not exceed 50,000 shares.
 
                                   SECTION 6
 
             TERMS AND CONDITIONS OF STOCK OPTIONS AND STOCK GRANTS
 
     General Terms and Conditions:  Stock options and stock grants awarded
pursuant to the Plan need not be identical but each stock option and stock grant
shall be subject to the following general terms and conditions:
 
          Terms and Restrictions Upon Shares:  The Board may provide that the
     shares of Common Stock issued upon exercise of a stock option or receipt of
     a stock grant shall be subject to such further conditions, restrictions or
     agreements as the Board in its discretion may specify prior to the exercise
     of such stock option or receipt of such stock grant, including without
     limitation, deferrals on issuance, conditions on vesting or
     transferability, and forfeiture or repurchase provisions. The Committee may
     establish rules for the deferred delivery of shares of Common Stock upon
     exercise of a stock option or receipt of a stock grant with the deferral
     evidenced by use of "Stock Units" equal in number to the number of shares
     of Common Stock whose delivery is so deferred. A "Stock Unit" is a
     bookkeeping entry representing an amount equivalent to the Fair Market
     Value of one share of Common Stock. Stock Units represent an unfunded and
     unsecured obligation of the Corporation except as otherwise provided by the
     Board. Settlement of Stock Units upon expiration of the deferral period
     shall be made in shares of Common Stock or otherwise as determined by the
     Committee. The amount of Common Stock, or other settlement medium, to be so
     distributed may be increased by an interest factor or by dividend
     equivalents. Until a Stock Unit is settled, the number of shares of Common
     Stock represented by a Stock Unit shall be subject to adjustment pursuant
     to Section 9.
 
          Transferability of Option:  Unless otherwise provided by the
     Committee, each stock option shall be transferable only by will or the laws
     of descent and distribution.
 
          Other Terms and Conditions:  No holder of a stock option or stock
     grant shall have any rights as a stockholder with respect to any shares of
     Common Stock subject to a stock option or stock grant hereunder until said
     shares have been issued. Stock options and stock grants may also contain
     such other provisions, which shall not be inconsistent with any of the
     foregoing terms, as the Board or the Committee shall deem appropriate. The
     Board may waive conditions to and/or accelerate exercisability of a stock
     option or stock grant, either automatically upon the occurrence of
     specified events (including in connection with a change of control of the
     Company) or otherwise in its discretion. No stock option or stock grant,
     however, nor anything contained in the Plan, shall confer upon any
     Participant any right to serve as a director of the Company.
 
                                       A-2
<PAGE>   39
 
          Stock Option Price:  The exercise price for each stock option shall be
     established by the Board or under a formula established by the Board. The
     exercise price shall not be less than the Fair Market Value of the stock on
     the date of grant. The exercise price shall be paid in full at the time of
     exercise. The exercise price shall be payable in cash, by payment under an
     arrangement with a broker where payment is made pursuant to an irrevocable
     direction to the broker to deliver all or part of the proceeds from the
     sale of the option shares to the Company, by the surrender of shares of
     Common Stock owned by the optionholder exercising the option and having a
     fair market value on the date of exercise equal to the exercise price but
     only if such will not result in an accounting charge to the Company, or by
     any combination of the foregoing. In addition, the exercise price shall be
     payable in such other form(s) of consideration as the Committee in its
     discretion shall specify, including without limitation by loan (as
     described in Section 8) or by techniques that may result in an accounting
     charge to the Company.
 
          Stock Grant Terms:  Stock grants under the Plan may, in the sole
     discretion of the Board, but need not, be conditioned upon the Participant
     paying cash or cash-equivalent consideration or agreeing to forego other
     compensation for the Shares covered by the stock grant. Stock grants under
     the Plan may be subject to such conditions, restrictions or other vesting
     terms as are established in the sole discretion of the Board. The
     conditions, restrictions or vesting terms may be contingent upon the
     passage of time, continued service or achievement of Company or individual
     performance goals, as specified by the Board.
 
                                   SECTION 7
 
                           ADMINISTRATION OF THE PLAN
 
     The Plan shall be administered by the Board, except that as provided herein
the Plan may be administered by a Committee of the Board, as appointed from time
to time by the Board. The Board shall fill vacancies on and from time to time
may remove or add members to the Committee.
 
     Subject to the express provisions of this Plan, the Committee shall be
authorized and empowered to do all things necessary or desirable in connection
with the administration of this Plan, including, without limitation: (a) to
prescribe, amend and rescind rules relating to this Plan and to define terms not
otherwise defined herein; (b) to prescribe the form of documentation used to
evidence any stock option or stock grant awarded hereunder, including provision
for such terms as it considers necessary or desirable, not inconsistent with the
terms established by the Board; (c) to establish and verify the extent of
satisfaction of any conditions to exercisability applicable to stock options or
to receipt or vesting of stock grants; (d) to determine whether, and the extent
to which, adjustments are required pursuant to Section 9 hereof; and (e) to
interpret and construe this Plan, any rules and regulations under the Plan and
the terms and conditions of any stock option or stock grant awarded hereunder,
and to make exceptions to any procedural provisions in good faith and for the
benefit of the Company. Notwithstanding any provision of this Plan, the Board
may at any time limit the authority of the Committee to administer this Plan.
 
     All decisions, determinations and interpretations by the Board or, except
as to the Board, the Committee regarding the Plan, any rules and regulations
under the Plan and the terms and conditions of any stock option or stock grant
awarded hereunder, shall be final and binding on all Participants and holders of
stock options and stock grants. The Board and the Committee may consider such
factors as it deems relevant, in its sole and absolute discretion, in making
such decisions, determinations and interpretations including, without
limitation, the recommendations or advice of any officer or other employee of
the Company and such attorneys, consultants and accountants as it may select.

                                   SECTION 8
 
                                     LOANS
 
     The Company may, if authorized by the Board, make loans for the purpose of
enabling a Participant to exercise stock options and, if applicable, receive
stock awarded under the Plan and to pay the tax liability resulting from a stock
option exercise or stock grant under the Plan. The Board shall have full
authority to determine the terms and conditions of such loans. Such loans may be
secured by the shares of Common Stock received upon exercise of such stock
option or receipt of such stock grant.
 
                                   SECTION 9
 
                     ADJUSTMENT OF AND CHANGES IN THE STOCK
 
     If the outstanding securities of the class then subject to this Plan are
increased, decreased or exchanged for or converted into cash, property or a
different number or kind of shares or securities, or if cash, property or shares
or securities are distributed in respect of such outstanding securities, in
either case as a result of a reorganization, reclassification, dividend (other
than a regular, quarterly cash dividend) or other distribution, stock split,
reverse stock split, spin-off or the like, or if substantially all of the
property and assets of the Company are sold, then, unless the terms of such
transaction shall provide otherwise, the maximum number and type of shares or
other securities that may be issued under this Plan shall be appropriately
adjusted. The Committee shall determine in its sole discretion the appropriate
adjustment to be effected pursuant to the immediately preceding sentence. In
addition, in connection with any such change in the class of securities then
subject to this Plan, the Committee may make appropriate and proportionate
adjustments in the number and type of shares or other securities or cash or
other property that may be acquired pursuant to stock options and stock grants
theretofore awarded under this Plan and the exercise price of such stock options
or price, if any, of such stock grants.
 
     No right to purchase or receive fractional shares shall result from any
adjustment in stock options or stock grants pursuant to this Section 9. In case
of any such adjustment, the shares subject to the stock option or stock grant
shall be rounded up to the nearest whole share of Common Stock.
 
                                   SECTION 10
 
                REGISTRATION, LISTING OR QUALIFICATION OF STOCK
 
     In the event that the Board or the Committee determines in its discretion
that the registration, listing or qualification of the shares of Common Stock
issuable under the Plan on any securities exchange or under any applicable law
or governmental regulation is necessary as a condition to the issuance of such
shares under the stock option or stock grant, the stock option or stock grant
shall not be exercisable or exercised in whole or in part unless such
registration, listing, qualification, consent or approval has been
unconditionally obtained.
 
                                   SECTION 11
 
                                     TAXES
 
     The Board or Committee may make such provisions or impose such conditions
as it may deem appropriate for the withholding or payment by a Participant of
any taxes which it determines are necessary or appropriate in connection with
any issuance of shares under this Plan, and the rights of a holder of a stock
option or stock grant in any shares are subject to satisfaction of such
conditions. The Company shall not be required to issue shares of Common Stock or
to recognize the disposition of such shares until such obligations are
satisfied. At the Participant's election, any such obligations may be satisfied
by having the Company withhold a portion of the shares of Common Stock that
otherwise would be issued to the holder of the stock option or stock grant upon
exercise of the stock option or vesting or receipt of the stock grant or by
surrendering to the Company shares of Common Stock previously acquired. The
Company and any affiliate of the Company shall not be liable to a Participant or
any other persons as to any tax consequence expected, but not realized, by any
Participant or other person due to the receipt of any stock options or shares
awarded hereunder.

                         ARBITRATION AND APPLICABLE LAW
 
     Any claim, dispute or other matter in question of any kind relating to this
Plan shall be settled by arbitration before a single arbitrator and otherwise
conducted in accordance with the Rules of the American Arbitration Association,
which proceedings shall be held in the city in which the Company's executive
offices are located. Notice of demand for arbitration shall be made in writing
to the opposing party and to the American Arbitration Association within a
reasonable time after the claim, dispute or other matter in question has arisen.
In no event shall a demand for arbitration be made after the date when the
applicable statute of limitations would bar the institution of a legal or
equitable proceeding based on such claim, dispute or other matter in question.
The decision of the arbitrator shall be final and may be enforced in any court
of competent jurisdiction. This Plan and any rights hereunder shall be
interpreted and construed in accordance with the laws of the State of Delaware
and applicable federal law.
 
                                   SECTION 13
 
               EFFECTIVE DATE, AMENDMENT AND TERMINATION OF PLAN
 
     This Plan shall become effective upon its approval by a majority of the
outstanding shares of the Company present, or represented by proxy, and entitled
to vote at the Company's 1999 annual meeting of stockholders to take place
following the conclusion of its 1998 fiscal year. Any stock options and stock
grants awarded prior to the such date shall be contingent on such approval and,
if such approval is not obtained, shall be null and of no effect.
 
     Unless earlier suspended or terminated by the Board, no stock options or
stock grants may be awarded after the tenth anniversary of the date the Plan is
approved by the Company's stockholders. The Board may periodically amend the
Plan as determined appropriate, without further action by the Company's
stockholders except to the extent required by applicable law. Notwithstanding
the foregoing, and subject to adjustment pursuant to Section 9, the Plan may not
be amended to increase the number of shares of Common Stock authorized for
issuance under the Plan, unless any such amendment is approved by the Company's
stockholders. The Plan may be earlier terminated at such earlier time as the
Board may determine. Termination and expiration of the Plan will not affect the
rights and obligations arising under stock options or stock grants theretofore
awarded and then in effect.

                              CSK AUTO CORPORATION
 
                        1996 EXECUTIVE STOCK OPTION PLAN
                      (AMENDED AND RESTATED JUNE 8, 1999)
 
1.  Purposes of the Plan.
 
     This stock option plan including Exhibit I hereto (the "Plan") is designed
to provide an incentive to employees (including directors and officers who are
employees) of and consultants to CSK AUTO CORPORATION, a Delaware corporation
(the "Company"), or any of its Subsidiaries or a Parent (as such terms are
defined in Paragraph 20), and to offer an additional inducement in obtaining the
services of such persons. The Plan provides for the grant of "incentive stock
options" ("ISOs") within the meaning of Section 422 of the Internal Revenue Code
of 1986, as amended (the "Code"), and nonqualified stock options which do not
qualify as ISOs ("NQSOs"), but the Company makes no representation or warranty,
express or implied, as to the qualification of any option as an "incentive stock
option" under the Code.
 
2.  Stock Subject to the Plan.
 
     Subject to the provisions of Paragraph 12, the aggregate number of shares
of Common Stock, $.01 par value per share, of the Company ("Common Stock") which
may be issued under the Plan shall not exceed 744,200. Such shares of Common
Stock may, in the discretion of the Board of Directors of the Company (the
"Board of Directors"), consist either in whole, or in part of authorized but
unissued shares of Common Stock or shares of Common Stock held in the treasury
of the Company. Subject to the provisions of Paragraph 14, any shares of Common
Stock subject to an option which for any reason expires, is canceled or is
terminated unexercised or which ceases for any reason to be exercisable shall
again become available for the granting of options under the Plan. The Company
shall at all times during the term of the Plan reserve and keep available such
number of shares of Common Stock as will be sufficient to satisfy the
requirements of the Plan.
 
3.  Administration of the Plan.
 
     The Plan shall be administered by the Board of Directors or by a committee
of the Board of Directors consisting of not less than two directors (in either
case, the "Committee"). During 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"), each member of the Committee shall be a
"Non-Employee Director" within the meaning of Rule 16b-3 promulgated under the
Exchange Act (as the same may be in effect and interpreted from time to time,
"Rule 16b-3"). A majority of the members of the Committee shall constitute a
quorum, and the acts of a majority of the members present at any meeting at
which a quorum is present, and any acts approved in writing by all members
without a meeting, shall be the acts of the Committee.
 
     Subject to the express provisions of the Plan, the Committee shall have the
authority, in its sole discretion to construe the respective Contracts and the
Plan; with the consent of the optionee, to cancel or modify an option, provided,
that the modified provision is permitted to be included in an option granted
under the Plan on the date of the modification, and further, provided, that in
the case of a modification (within the meaning of Section 424(h) of the Code) of
an ISO, such option as modified would be permitted to be granted on the date of
such modification under the terms of the Plan; to prescribe, amend and rescind
rules and regulations relating to the Plan; to approve any provision which under
Rule 16b-3 requires approval by a committee of Non-Employee Directors to be
exempt (unless otherwise specifically provided herein); and to make all other
determinations necessary or advisable for granting options or administering the
Plan, including: the employees and consultants who shall be granted options; the
times when options shall be granted; whether an option shall be an ISO or a
NQSO; the number of shares of Common Stock to be subject to each option; the
term of each option; the date each option shall become exercisable; whether an
option shall be exercisable in whole, in part or in installments and, if in
installments, the number of shares of Common Stock to be subject to each
installment, whether the installments shall be cumulative, the date each
installment shall become exercisable and the term of each installment; whether
to accelerate the date of exercise of any option or installment;
 
                                       B-1
<PAGE>   43
 
whether shares of Common Stock may be issued upon the exercise of an option as
partly paid and, if so, the dates when future installments of the exercise price
shall become due and the amounts of such installments; the exercise price of
each option; the form of payment of the exercise price; whether to restrict the
sale or other disposition of the shares of Common Stock acquired upon the
exercise of an option and, if so, whether to waive any such restriction; whether
to subject the grant or exercise of all or any portion of an option to the
fulfillment of contingencies as specified in the contract referred to in
Paragraph 11 (the "Contract"), including without limitation, contingencies
relating to entering into a covenant not to compete with the Company, any of its
Subsidiaries or a Parent, to financial objectives for the Company, any of its
Subsidiaries or a Parent, a division of any of the foregoing, a product line or
other category, and/or the period of continued employment of the optionee with
the Company, any of its Subsidiaries or a Parent, and to determine whether such
contingencies have been met; whether an optionee is Disabled (as defined in
Paragraph 20); the amount, if any, necessary to satisfy the obligation of the
Company, a Subsidiary or a Parent to withhold taxes or other amounts; the fair
market value of a share of Common Stock. Any controversy or claim arising out of
or relating to the Plan, any option granted under the Plan or any Contract shall
be determined unilaterally by the Committee in its sole discretion. The
determinations of the Committee on the matters referred to in this Paragraph 3
shall be conclusive and binding on the parties.
 
     No member or former member of the Committee shall be liable for any action,
failure to act or determination made in good faith with respect to the Plan or
any option hereunder. In addition, the Company shall indemnify and hold harmless
each member and former member of the Committee and their respective successors,
assigns, heirs and personal representatives from and against any liability,
loss, claim, damage and expense (including without limitation attorneys fees and
expenses) incurred in connection therewith by reason of any action, failure to
act or determination made in good faith under or in connection with the Plan or
any option hereunder to the fullest extent permitted with respect to directors
under the Company's certificate of incorporation, by-laws or applicable law.
 
4.  Eligibility.
 
     The Committee may from time to time, in its sole discretion, consistent
with the purposes of the Plan, grant options to employees (including officers
and directors who are employees) of, and to consultants to, the Company or any
of its Subsidiaries, or a Parent of the Company. Such options granted shall
cover such number of shares of Common Stock as the Committee may determine, in
its sole discretion; provided, however, that if the Company is a "publicly held
corporation" (within the meaning of Code Section 162(m)), the maximum number of
shares of Common Stock subject to options that may be granted to any employee
during any fiscal year of the Company under the Plan shall be 684,200 shares
(the "162(m) Maximum"); and further, provided, that the aggregate market value
(determined at the time the option is granted in accordance with Paragraph 5) of
the shares of Common Stock for which any eligible employee may be granted ISOs
under the Plan or any other plan of the Company, or of a Parent or a Subsidiary
of the Company, which are exercisable for the first time by such optionee during
any calendar year shall not exceed $100,000. Such ISO limitation shall be
applied by taking ISOs into account in the order in which they were granted. Any
option (or the portion thereof) granted in excess of such ISO limitation amount
shall be treated as a NQSO.
 
5.  Exercise Price.
 
     The exercise price of the shares of Common Stock under each option shall be
determined by the Committee in its sole discretion; provided, however, that the
exercise price of an ISO shall not be less than the fair market value of the
Common Stock subject to such option on the date of grant; and further, provided,
that if, at the time an ISO is granted, the optionee owns (or is deemed to own
under Section 424(d) of the Code) stock possessing more than 10% of the total
combined voting power of all classes of stock of the Company, of any of its
Subsidiaries or of a Parent, the exercise price of such ISO shall not be less
than 110% of the fair market value of the Common Stock subject to such ISO on
the date of grant.
 
     The fair market value of a share of Common Stock on any day shall be (a) if
the principal market for the Common Stock is a national securities exchange, the
average of the highest and lowest sales prices per share of Common Stock on such
day as reported by such exchange or on a composite tape reflecting transactions
on such exchange, (b) if the principal market for the Common Stock is not a
national securities exchange and
                                       B-2
<PAGE>   44
 
the Common Stock is quoted on The Nasdaq Stock Market ("Nasdaq"), and (i) if
actual sales price information is available with respect to the Common Stock,
the average of the highest and lowest sales prices per share of Common Stock on
such day on Nasdaq, or (ii) if such information is not available, the average of
the highest bid and lowest asked prices per share of Common Stock on such day on
Nasdaq, or (c) if the principal market for the Common Stock is not a national
securities exchange and the Common Stock is not quoted on Nasdaq, the average of
the highest bid and lowest asked prices per share of Common Stock on such day as
reported on the OTC Bulletin Board Service or by National Quotation Bureau,
Incorporated or a comparable service; provided, however, that if clauses (a),
(b) and (c) of this Paragraph are all inapplicable, or if no trades have been
made or no quotes are available for such day, the fair market value of the
Common Stock shall be determined by the Board by any method consistent with
applicable regulations adopted by the Treasury Department relating to stock
options.
 
6.  Term.
 
     The term of each option granted pursuant to the Plan shall be such term as
is established by the Committee, in its sole discretion; provided, however, that
the term of each ISO granted pursuant to the Plan shall be for a period not
exceeding 10 years from the date of grant thereof; and further, provided, that
if, at the time an ISO is granted, the optionee owns (or is deemed to own under
Section 424(d) of the Code) stock possessing more than 10% of the total combined
voting power of all classes of stock of the Company, of any of its Subsidiaries
or of a Parent, the term of the ISO shall be for a period not exceeding five
years from the date of grant. Options shall be subject to earlier termination as
hereinafter provided.
 
7.  Exercise; Adjustment of Shares Subject to Options.
 
     Unless provided otherwise by the Committee, options granted hereunder shall
vest and become exercisable in accordance with Exhibit I to this Plan, which is
incorporated by reference herein and made a part hereof. In addition, the number
of shares of Common Stock subject to each option is subject to automatic
increase upon the terms and conditions described on Exhibit I to this Plan.
 
     An option (or any part or installment thereof), to the extent then
exercisable, shall be exercised by giving written notice to the Company (in
advance as determined by the Committee) at its principal office stating which
option is being exercised, specifying the number of shares of Common Stock as to
which such option is being exercised and accompanied by payment in full of the
aggregate exercise price therefor (or the amount due on exercise if the Contract
permits installment payments) (a) in cash or by certified check or (b) if the
applicable Contract permits, with previously acquired shares of Common Stock
having an aggregate fair market value on the date of exercise (determined in
accordance with Paragraph 5) equal to the aggregate exercise price of all
options being exercised, or with any combination of cash, certified check or
shares of Common Stock having such value. The Company shall not be required to
issue any shares of Common Stock pursuant to any such option until all required
payments, including any required withholding, have been made.
 
     Notwithstanding the foregoing, the Committee may, in its sole discretion,
permit payment of the exercise price of an option by delivery by the optionee of
a properly executed notice, together with a copy of his irrevocable instructions
to a broker acceptable to the Committee to deliver promptly to the Company the
amount of sale or loan proceeds sufficient to pay such exercise price. In
connection therewith, the Company may enter into agreements for coordinated
procedures with one or more brokerage firms.
 
     A person entitled to receive Common Stock upon the exercise of an option
shall not have the rights of a stockholder with respect to such shares of Common
Stock until the date of issuance of a stock certificate to him for such shares;
provided, however, that until such stock certificate is issued, any optionee
using previously acquired shares of Common Stock in payment of an option
exercise price shall continue to have the rights of a stockholder with respect
to such previously acquired shares.
 
     In no case may a fraction of a share of Common Stock be purchased or issued
under the Plan.
 
8.  Termination of Relationship.
 
     Except as may otherwise be expressly provided in the applicable Contract,
any optionee whose relationship with the Company, its Parent and Subsidiaries as
an employee or a consultant (a "Relationship")
                                       B-3
<PAGE>   45
 
has terminated for any reason (other than as a result of the death or Disability
of the optionee) may exercise such option, to the extent exercisable on the date
of such termination, at any time during the 30 days commencing six months after
the date of such termination, but not thereafter. Notwithstanding the foregoing,
if such Relationship is terminated (a) for cause, or (b) if at any time during
the first six months after termination of the Relationship the optionee shall be
directly or indirectly employed by, associated with, or affiliated with, a chain
of automotive after market stores which in the Board of Directors' judgment is a
competitor of the Company, such optionee shall have no rights to exercise such
option.
 
     For the purposes of the Plan, an employment relationship shall be deemed to
exist between an individual and a corporation if, at the time of the
determination, the individual was an employee of such corporation for purposes
of Section 422(a) of the Code. As a result, an individual on military, sick
leave or other bona fide leave of absence shall continue to be considered an
employee for purposes of the Plan during such leave if the period of the leave
does not exceed 90 days, or, if longer, so long as the individual's right to
reemployment with the Company (or a related corporation) is guaranteed either by
statute or by contract. If the period of leave exceeds 90 days and the
individual's right to reemployment is not guaranteed by statute or by contract,
the employment relationship shall be deemed to have terminated on the 91st day
of such leave.
 
     Except as may otherwise be expressly provided in the applicable Contract,
options granted under the Plan shall not be affected by any change in the status
of the optionee so long as the optionee continues to be an employee of, or a
consultant to, the Company, or any of its Subsidiaries or a Parent (regardless
of having changed from one to the other or having been transferred from one
corporation to another).
 
     Nothing in the Plan or in any option granted under the Plan shall confer on
any optionee any right to continue in the employ of, or as a consultant to, the
Company, any of its Subsidiaries or a Parent, or interfere in any way with any
right of the Company, any of its Subsidiaries or a Parent to terminate the
optionee's relationship at any time for any reason whatsoever without liability
to the Company, its Subsidiaries or Parent.
 
     For purposes of this Plan, "cause" shall mean fraud or embezzlement by the
optionee, gross negligence by the optionee in the performance or nonperformance
of his duties for the Company, its Subsidiaries or Parent, or the optionee's
material failure or refusal to perform his duties at any time as an employee of
or consultant to the Company, a Subsidiary or Parent.
 
9.  Death or Disability of an Optionee.
 
     Except as may otherwise be expressly provided in the applicable Contract,
if an optionee dies while he or she is an employee of, or consultant to, the
Company, any of its Subsidiaries or a Parent, or his or her Relationship
terminates by reason of his or her Disability, the option may be exercised, to
the extent exercisable on the date of his or her death or in the event of his or
her Disability, upon the effective date of such termination, by his or her Legal
Representative (as defined in Paragraph 20) at any time within 90 days after the
date of death or the effective date of such termination, but not thereafter.
 
10.  Compliance with Securities Laws.
 
     The Committee may require, in its sole discretion, as a condition to any
option being exercisable that either (a) a Registration Statement under the
Securities Act of 1933, as amended (the "Securities Act"), with respect to the
shares of Common Stock to be issued upon such exercise shall be effective and
current at the time of exercise, or (b) there is an exemption from registration
under the Securities Act for the issuance of the shares of Common Stock upon
such exercise. Nothing herein shall be construed as requiring the Company to
register shares subject to any option under the Securities Act or to keep any
Registration Statement effective or current.
 
     The Committee may require, in its sole discretion, as a condition to the
exercise of any option that the optionee execute and deliver to the Company his
representations and warranties, in form, substance and scope satisfactory to the
Committee, which the Committee determines are necessary or convenient to
facilitate the perfection of an exemption from the registration requirements of
the Securities Act, applicable state securities laws or other legal requirement,
including without limitation that (a) the shares of Common Stock to be issued
upon the exercise of the option are being acquired by the optionee for his own
account, for investment
 
                                       B-4
<PAGE>   46
 
only and not with a view to the resale or distribution thereof, and (b) any
subsequent resale or distribution of shares of Common Stock by such optionee
will be made only pursuant to (i) a Registration Statement under the Securities
Act which is effective and current with respect to the shares of Common Stock
being sold, or (ii) a specific exemption from the registration requirements of
the Securities Act, but in claiming such exemption, the optionee shall prior to
any offer of sale or sale of such shares of Common Stock provide the Company
with a favorable written opinion of counsel satisfactory to the Company, in
form, substance and scope satisfactory to the Company, as to the applicability
of such exemption to the proposed sale or distribution.
 
     In addition, if at any time the Committee shall determine, in its sole
discretion, that the listing or qualification of the shares of Common Stock
subject to such option on any securities exchange, Nasdaq or under any
applicable law, or the consent or approval of any governmental authority or
regulatory body, is necessary or desirable as a condition to, or in connection
with, the granting of an option or the issue of shares of Common Stock
thereunder, such option may not be exercised in whole or in part unless such
listing, qualification, consent or approval shall have been effected or obtained
free of any conditions not acceptable to the Committee.
 
     No Optionee shall transfer any shares of Common Stock, except pursuant to
an effective registration Statement under the Securities Act or pursuant to Rule
144 under the Securities Act.
 
11.  Stock Option Contracts.
 
     Each option shall be evidenced by an appropriate Contract which shall be
duly executed by the Company and the optionee, and shall contain such terms,
provisions and conditions not inconsistent herewith as may be determined by the
Committee.
 
12.  Adjustments upon Changes in Common Stock.
 
     Notwithstanding any other provision of the Plan, in the event of a stock
dividend, spin-off, split-up, combination, reclassification, recapitalization,
merger in which the Company is the surviving corporation, or exchange of shares
or the like which results in a change in the number or kind of shares of Common
Stock which are authorized for issuance or which are outstanding immediately
prior to such event, the aggregate number and kind of shares subject to the
Plan, the aggregate number and kind of shares subject to each outstanding option
and the exercise price thereof, and the 162(m) Maximum shall be adjusted
accordingly by the Board of Directors, whose determination shall be conclusive
and binding on all parties.
 
13.  Certain Sales of the Company.
 
     a) In the event that, at any time during the term of an option, there shall
be (i) a sale of shares of capital stock by one or more stockholders, which
results in shares of capital stock having an aggregate of 80% of the voting
power of all outstanding shares of capital stock being owned, directly or
indirectly, by one or more related persons, or (ii) the sale of 80% or more of
the Company's assets in any one transaction or series of related transactions,
in either case to parties which at the time of such sales were not stockholders
or affiliates of any stockholder of the Company (collectively, "Sales" and the
final such sale being the "Triggering Sale"), the portion of such option which
remains unvested at the time of the Triggering Sale shall vest upon the
occurrence of the Triggering Sale.
 
     b) Notwithstanding anything to the contrary contained herein, until an
optionee is notified in writing by the Company that all provisions of the
Stockholders' Agreement, dated as of October 30, 1996, among the Company and
certain of its stockholders (the "Stockholders' Agreement") relating to the
purchase and sale of the Company's securities (other than in a public offering)
have terminated, all shares of Common Stock issued upon the exercise of options
granted hereunder shall be subject to the following restrictions and have the
following rights:
 
          (i) If, pursuant to the terms of the Stockholders' Agreement in
     connection with an arm's-length sale to an unaffiliated third party
     pursuant to a written offer to purchase at least all of the securities of
     the Company held by the stockholders party to the Stockholders' Agreement,
     certain of the stockholders party to the Stockholders' Agreement (the
     "Moving Group") have the right to require the other holders
                                       B-5
<PAGE>   47
 
     of securities bound by the terms of the Stockholders' Agreement (the
     "Selling Stockholders") to sell all of their equity securities of the
     Company either to the third party or to the Moving Stockholders and/or the
     Company (the "Purchaser") for consideration per share having at least the
     same value as the consideration proposed to be paid by the third party, the
     Moving Group shall also have the right to require each optionee to sell,
     and each optionee shall sell and deliver free and clear of all liens,
     claims and encumbrances, all of each optionee's Common Stock in the same
     transaction to the Purchaser, provided, however, that such optionee
     receives the same terms, including, without limitation, the same
     consideration per share of Common Stock, as is received in such
     transactions by the Selling Stockholders.
 
          (ii) If, pursuant to the terms of the Stockholders' Agreement in
     connection with a proposed sale of more than 25% of the outstanding equity
     securities of the Company by certain of the stockholders party to the
     Stockholders' Agreement (the "Transferring Stockholders"), such sale by
     such Transferring Stockholders cannot be consummated unless (y) prior to
     such sale each of the other stockholders party to the Stockholders'
     Agreement (the "Other Stockholders") and the Company shall have been given
     notice of the proposed transaction, which notice shall specify the number
     of shares that the Transferring Stockholders desire to sell, the identity
     of the prospective purchaser (the "Buyer"), and the proposed terms thereof
     and shall also include a copy of the written offer from the Buyer, and (z)
     each of the Other Stockholders shall have been provided a firm irrevocable
     right, which right shall be exercisable by written notice (which shall
     specify the number of shares (up to the total number of shares held by the
     Transferring Stockholders) that the Other Stockholders desire to sell)
     within 60 days after giving notice to the Other Stockholders, to sell to
     the Buyer, at the same time and upon the same terms and conditions offered
     to the Transferring Stockholders by the Buyer, the number of shares of
     Common Stock of the Other Stockholders (the "Proportionate Amount") that
     bears the same ratio to the total number of shares of Common Stock held by
     the Other Stockholders as the total number of shares of Common Stock
     proposed to be sold by the Transferring Stockholders to the Buyer bears to
     the total number of shares of Common Stock held by all of the Transferring
     Stockholders, the Company will not register the transfer of securities from
     the Transferring Stockholders to the Buyer unless the Transferring
     Stockholders and the Buyer shall have extended to each optionee the rights
     described above which are required to be extended to Other Stockholders in
     connection with such a sale.
 
14.  Amendments and Termination of the Plan.
 
     The Plan was originally adopted by the Board of Directors on February 10,
1997. No option may be granted under the Plan after October 30, 2006. The Board
of Directors, without further approval of the Company's stockholders, may at any
time suspend or terminate the Plan, in whole or in part, or amend it from time
to time in such respects as it may deem advisable, including, without
limitation, in order that ISOs granted hereunder meet the requirements for
"incentive stock options" under the Code, to comply with the provisions of Rule
16b-3, Section 162(m) of the Code, or any change in applicable law, regulations,
rulings or interpretations of administrative agencies; provided, however, that
no amendment shall be effective without the prior or subsequent stockholder
approval required under applicable law or the Code which would (a) except as
contemplated in Paragraph 12, increase the maximum number of shares of Common
Stock for which options may be granted under the Plan or the 162(m) Maximum, or
(b) change the eligibility requirements to receive options hereunder. No
termination, suspension or amendment of the Plan shall, without the consent of
the holder of an existing and outstanding option affected thereby, adversely
affect his rights under such option. The power of the Committee to construe and
administer any options granted under the Plan prior to the termination or
suspension of the Plan nevertheless shall continue after such termination or
during such suspension.
 
15.  Non-transferability of Options.
 
     No option granted under the Plan shall be transferable otherwise than by
will or the laws of descent and distribution, and options may be exercised,
during the lifetime of the optionee, only by the optionee or his Legal
Representatives. Except to the extent provided above, options may not be
assigned, transferred, pledged, hypothecated or disposed of in any way (whether
by operation of law or otherwise) and shall not be subject to
 
                                       B-6
<PAGE>   48
 
execution, attachment or similar process, and any such attempted assignment,
transfer, pledge, hypothecation or disposition shall be null and void ab initio
and of no force or effect.
 
16.  Withholding Taxes.
 
     The Company may withhold (a) cash, (b) subject to any limitations under
Rule 16b-3, shares of Common Stock to be issued with respect thereto having an
aggregate fair market value on the exercise date (determined in accordance with
Paragraph 5), or (c) any combination thereof, in an amount equal to the amount
which the Committee determines is necessary to satisfy the obligation of the
Company, a Subsidiary or a Parent to withhold Federal, state and local income
taxes or other amounts incurred by reason of the grant or exercise of an option,
its disposition, or the disposition of the underlying shares of Common Stock.
Alternatively, the Company may require the holder to pay to the Company such
amount, in cash, promptly upon demand.
 
17.  Legends; Payment of Expenses.
 
     The Company may endorse such legend or legends upon the certificates for
shares of Common Stock issued upon exercise of an option under the Plan and may
issue such "stop transfer" instructions to its transfer agent in respect of such
shares as it determines, in its discretion, to be necessary or appropriate to
(a) prevent a violation of, or to perfect an exemption from, the registration
requirements of the Securities Act and any applicable state securities laws, (b)
implement the provisions of the Plan or any agreement between the Company and
the optionee with respect to such shares of Common Stock, or (c) permit the
Company to determine the occurrence of a "disqualifying disposition," as
described in Section 421(b) of the Code, of the shares of Common Stock issued or
transferred upon the exercise of an ISO granted under the Plan.
 
     The Company shall pay all issuance taxes with respect to the issuance of
shares of Common Stock upon the exercise of an option granted under the Plan, as
well as all fees and expenses incurred by the Company in connection with such
issuance.
 
18.  Use of Proceeds.
 
     The cash proceeds from the sale of shares of Common Stock pursuant to the
exercise of options under the Plan shall be added to the general funds of the
Company and used for such corporate purposes as the Board of Directors may
determine.
 
19.  Substitutions and Assumptions of Options of Certain Constituent
Corporations.
 
     Anything in this Plan to the contrary notwithstanding, the Board of
Directors may, without further approval by the stockholders, substitute new
options for prior options of a Constituent Corporation (as defined in Paragraph
20) or assume the prior options of such Constituent Corporation.
 
20.  Definitions.
 
     For purposes of the Plan, the following terms shall be defined as set forth
below:
 
          a) Constituent Corporation.  The term "Constituent Corporation" shall
     mean any corporation which engages with the Company, any of its
     Subsidiaries or a Parent in a transaction to which Section 424(a) of the
     Code applies (or would apply if the option assumed or substituted were an
     ISO), or any Parent or any Subsidiary of such corporation.
 
          b) Disability.  The term "Disability" shall mean a permanent and total
     disability within the meaning of Section 22(e)(3) of the Code.
 
          c) Legal Representative.  The term "Legal Representative" shall mean
     the executor, administrator or other person who at the time is entitled by
     law to exercise the rights of a deceased or incapacitated optionee with
     respect to an option granted under the Plan.
 
          d) Parent.  The term "Parent" shall have the same definition as
     "parent corporation" in Section 424(e) of the Code.
 
                                       B-7
<PAGE>   49
 
          e) Subsidiary.  The term "Subsidiary" shall have the same definition
     as "subsidiary corporation" in Section 424(f) of the Code.
 
21.  Governing Law; Construction.
 
     The Plan, such options as may be granted hereunder and all related matters
shall be governed by, and construed in accordance with, the laws of the State of
Delaware, without regard to conflict of law provisions.
 
     Neither the Plan nor any Contract shall be construed or interpreted with
any presumption against the Company by reason of the Company causing the Plan or
Contract to be drafted. Whenever from the context it appears appropriate, any
term stated in either the singular or plural shall include the singular and
plural, and any term stated in the masculine, feminine or neuter gender shall
include the masculine, feminine and neuter.
 
22.  Partial Invalidity.
 
     The invalidity, illegality or unenforceability of any provision in the Plan
or any Contract shall not affect the validity, legality or enforceability of any
other provision, all of which shall be valid, legal and enforceable to the
fullest extent permitted by applicable law.
 
23.  Stockholder Approval.
 
     The Plan was originally approved by the Board as of February 10, 1997, and
by the unanimous written consent of the stockholders of the Corporation as of
February 9, 1998. Certain amendments to the plan requiring stockholder approval
were approved by the Board and the stockholders as of February 9, 1998. The Plan
was also amended and restated on June 5, 1998. This amendment and restatement
became effective on June 8, 1999, the date of its approval by the stockholders
of the Corporation.

                                   EXHIBIT I
 
              VESTING OF OPTIONS AND AUTOMATIC OPTION ADJUSTMENTS
 
     Each option granted under the Plan to optionees to purchase shares of
Common Stock will vest as follows:
 
          (a) 28% of the shares of Common Stock (rounded up or down to the
     nearest whole share of Common Stock) subject to such option will vest on
     the second anniversary date of the grant of the option and an additional
     28% (rounded up or down to the nearest whole share of Common Stock) will
     vest, on each of the third and fourth anniversary dates of grant.
 
          (b) The remaining 16% of the shares of Common Stock subject to such
     option will vest as follows:
 
             (i) 6%, 5% and 5%, respectively, of the shares of Common Stock
        (rounded up or down to the nearest whole share of Common Stock) subject
        to such option will vest, on each of the first, second and third April
        30th to occur after the second anniversary of the date of grant (each a
        "Business Plan Vest Date"), if at least 95% of the Option Target
        ("Option Target") applicable to such optionee as set forth in the
        Company's Management Business Plan attached hereto shall be achieved for
        the immediately preceding full fiscal year (each, a "Target Year") or,
        with respect to the first Business Plan Vest Date, for the immediately
        preceding two full fiscal years on a cumulative basis; or
 
             (ii) In the event that between 75% and 95% of an Option Target
        shall be achieved for a Target Year or, with respect to the first
        Business Plan Vest Date for the first two Target Years on a cumulative
        basis, then (I) with respect to such first two Target Years, for each
        whole percent above 75% (and with respect to the last whole percent
        between 94% and 95%, 94.99 shall be considered a whole percentage point
        for purposes of this calculation) of an Option Target that shall be
        achieved, an additional 3.0% of the shares of Common Stock subject to
        such option shall vest in respect of such Target Years (rounded up or
        down to the nearest whole share of Common Stock) and (II) with respect
        to each subsequent Target Year, for each whole percent above 75% (and
        with respect to the last whole percent between 94% and 95%, 94.99 shall
        be considered a whole percentage point for purposes of this calculation)
        of an Option Target that shall be achieved, an additional 2.5% of the
        shares of Common Stock subject to such option shall vest in respect of
        such Target Year (rounded up or down to the nearest whole share of
        Common Stock); or
 
             (iii) In the event that 75% or less of an Option Target shall be
        achieved for a Target Year or, with respect to the first Business Plan
        Vest Date for the first two Target Years on a cumulative basis, then no
        additional shares of Common Stock subject to such option shall vest in
        respect of such Target Year or Target Years.
 
             (iv) Notwithstanding clauses (ii) and (iii) above, if the Option
        Target for such optionee shall not have been achieved for any Target
        Year, but at least 95% of the sum of the Option Targets for (a) the
        first two Target Years and the third Target Year, (b) the third Target
        Year and the fourth Target Year, or (c) the first two Target Years, the
        third Target Year and the fourth Target Year, shall have been achieved
        as at the end of any such period, then the shares of Common Stock that
        would have vested if 100% of the Option Target had been achieved for
        each such Target Year in the applicable period, but did not so vest,
        shall nevertheless vest on the first Business Plan Vest Date thereafter.
        The Option Target for each Target Year following the date of grant of an
        option shall be appended to the Contract between the Company and the
        optionee.
 
             (v) Any of the shares of Common Stock subject to such option which
        shall not have vested pursuant to clauses (i), (ii), (iii) and (iv)
        above, shall automatically vest 90 days prior to the end of such
        option's term.
 
          (c) In the event that the Option Target applicable to an optionee
     shall be achieved with respect to any Target Year represented by each of
     the first four full fiscal years during an option's term, and exceeded by
     at least 10% (the number of percentage points of such excess over 10% being
     referred to as the "Excess"), then, in addition to the shares of Common
     Stock that shall vest in accordance with the
                                       B-9
<PAGE>   51
 
     preceding clauses above in subparagraph (b), the optionee shall
     automatically be granted on the first Business Plan Vest Date after the
     applicable Target Year (or with respect to the first two Target Years, for
     each of such two Target Years on the first Business Plan Vest Date) an
     additional option (the "Additional Option") to purchase shares of Common
     Stock (rounded up or down to the nearest whole share of Common Stock) equal
     to the product of (i) 5% of the aggregate number of shares of Common Stock
     originally subject to stock options granted to such optionee and (ii) a
     fraction, the numerator of which is the Excess (rounded up or down to the
     nearest one-tenth of a percent) and the denominator of which is 10;
     provided, however, that the maximum number of shares of Common Stock
     subject to the Additional Options granted with respect to any single Target
     Year shall not exceed 5% of the number of shares of Common Stock subject to
     the original Option granted prior thereto. Additional Options shall be 100%
     vested upon their grant. The exercise price of the shares of Common Stock
     under each Additional Option shall be equal to the fair market value of the
     Common Stock on the grant date of the original option.

                              CSK AUTO CORPORATION
 
                        1999 EMPLOYEE STOCK OPTION PLAN
 
1.  Purposes of the Plan.
 
     This stock option plan (the "Plan") is designed to provide an incentive to
employees (including directors and officers who are employees) of and
consultants to CSK AUTO CORPORATION, a Delaware corporation (the "Company"), or
any of its Subsidiaries or a Parent (as such terms are defined in Paragraph 20),
and to offer an additional inducement in obtaining the services of such persons.
The Plan provides for the grant of "incentive stock options" ("ISOs") within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), and nonqualified stock options which do not qualify as ISOs ("NQSOs"),
but the Company makes no representation or warranty, express or implied, as to
the qualification of any option as an "incentive stock option" under the Code.
 
2.  Stock Subject to the Plan.
 
     Subject to the provisions of Paragraph 12, the aggregate number of shares
of Common Stock, $.01 par value per share, of the Company ("Common Stock")
options for which may be issued under the Plan shall not exceed 750,000. Such
shares of Common Stock may, in the discretion of the Board of Directors of the
Company (the "Board of Directors"), consist either in whole or in part of
authorized but unissued shares of Common Stock or shares of Common Stock held in
the treasury of the Company. Subject to the provisions of Paragraph 14, any
shares of Common Stock subject to an option which for any reason expires, is
canceled or is terminated unexercised or which ceases for any reason to be
exercisable shall again become available for the granting of options under the
Plan. The Company shall at all times during the term of the Plan reserve and
keep available such number of shares of Common Stock as will be sufficient to
satisfy the requirements of the Plan.
 
3.  Administration of the Plan.
 
     The Plan shall be administered by the Board of Directors or by a committee
of the Board of Directors consisting of not less than two directors (in either
case, the "Committee"). During 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"), each member of the Committee shall be both (a)
a "Non-Employee Director" within the meaning of Rule 16b-3 promulgated under the
Exchange Act (as the same may be in effect and interpreted from time to time,
"Rule 16b-3") and (b) an "Outside Director" within the meaning of Section
162(m)(4)(C)(i) of the Code. A majority of the members of the Committee shall
constitute a quorum, and the acts of a majority of the members present at any
meeting at which a quorum is present, and any acts approved in writing by all
members without a meeting, shall be the acts of the Committee.
 
     Subject to the express provisions of the Plan, the Committee shall have the
authority, in its sole discretion: to construe the respective Contracts and the
Plan; with the consent of the optionee, to cancel or modify an option, provided,
that the modified provision is permitted to be included in an option granted
under the Plan on the date of the modification, and further, provided, that in
the case of a modification (within the meaning of Section 424(h) of the Code) of
an ISO, such option as modified would be permitted to be granted on the date of
such modification under the terms of the Plan; to prescribe, amend and rescind
rules and regulations relating to the Plan; to approve any provision which under
Rule 16b-3 requires approval by a committee of Non-Employee Directors to be
exempt (unless otherwise specifically provided herein); and to make all other
determinations necessary or advisable for granting options or administering the
Plan, including: the employees and consultants who shall be granted options; the
times when options shall be granted; whether an option shall be an ISO or a
NQSO; the number of shares of Common Stock to be subject to each option; the
term of each option; the date on which each option shall become exercisable;
whether an option shall be exercisable in whole, in part or in installments and,
if in installments, the number of shares of Common Stock to be subject to each
installment, whether the installments shall be cumulative, the date each
installment shall
 
                                       C-1
<PAGE>   53
 
become exercisable and the term of each installment; whether to accelerate the
date of exercise of any option or installment; whether shares of Common Stock
may be issued upon the exercise of an option as partly paid and, if so, the
dates when future installments of the exercise price shall become due and the
amounts of such installments; the exercise price of each option; the form of
payment of the exercise price; whether to restrict the sale or other disposition
of the shares of Common Stock acquired upon the exercise of an option and, if
so, whether to waive any such restriction; whether to subject the grant or
exercise of all or any portion of an option to the fulfillment of contingencies
as specified in the contract referred to in Paragraph 11 (the "Contract"),
including without limitation, contingencies relating to entering into a covenant
not to compete with the Company, any of its Subsidiaries or a Parent, to
financial objectives for the Company, any of its Subsidiaries or a Parent, a
division of any of the foregoing, a product line or other category and/or the
period of continued employment of the optionee with the Company, any of its
Subsidiaries or a Parent, and to determine whether such contingencies have been
met; whether an optionee is Disabled (as defined in Paragraph 20); the amount,
if any, necessary to satisfy the obligation of the Company, a Subsidiary or a
Parent to withhold taxes or other amounts; the fair market value of a share of
Common Stock. Any controversy or claim arising out of or relating to the Plan,
any option granted under the Plan or any Contract shall be determined
unilaterally by the Committee in its sole discretion. The determinations of the
Committee on the matters referred to in this Paragraph 3 shall be conclusive and
binding on the parties.
 
     No member or former member of the Committee shall be liable for any action,
failure to act or determination made in good faith with respect to the Plan or
any option hereunder. In addition, the Company shall indemnify and hold harmless
each member and former member of the Committee and their respective successors,
assigns, heirs and personal representatives from and against any liability,
loss, claim, damage and expense (including without limitation attorneys fees and
expenses) incurred in connection therewith by reason of any action, failure to
act or determination made in good faith under or in connection with the Plan or
any option hereunder to the fullest extent permitted with respect to directors
under the Company's certificate of incorporation, by-laws or applicable law.
 
4.  Eligibility.
 
     The Committee may from time to time, in its sole discretion, consistent
with the purposes of the Plan, grant options to employees (including officers
and directors who are employees) of, and to consultants to, the Company or any
of its Subsidiaries, or a Parent of the Company. Such options granted shall
cover such number of shares of Common Stock as the Committee may determine, in
its sole discretion; provided, however, that if the Company is a "publicly held
corporation" (within the meaning of Code Section 162(m)), the maximum number of
shares of Common Stock subject to options that may be granted to any employee
during any fiscal year of the Company under the Plan shall be 150,000 shares,
provided further, however, that only in the case of an employee hired by the
Company during the fiscal year, the maximum number of shares of Common Stock
subject to options that may be granted to such employee during such fiscal year
of the Company under the Plan shall be 250,000 shares (the "162(m) Maximum");
and further, provided, that the aggregate market value (determined at the time
the option is granted in accordance with Paragraph 5) of the shares of Common
Stock for which any eligible employee may be granted ISOs under the Plan or any
other plan of the Company, or of a Parent or a Subsidiary of the Company, which
are exercisable for the first time by such optionee during any calendar year
shall not exceed $100,000. Such ISO limitation shall be applied by taking ISOs
into account in the order in which they were granted. Any option (or the portion
thereof) granted in excess of such ISO limitation amount shall be treated as a
NQSO.
 
5.  Exercise Price.
 
     The exercise price of the shares of Common Stock under each option shall be
determined by the Committee in its sole discretion; provided, however, that the
exercise price of an ISO shall not be less than the fair market value of the
Common Stock subject to such option on the date of grant; and further, provided,
that if, at the time an ISO is granted, the optionee owns (or is deemed to own
under Section 424(d) of the Code) stock possessing more than 10% of the total
combined voting power of all classes of stock of the Company, of any of its
Subsidiaries or of a Parent, the exercise price of such ISO shall not be less
than 110% of the fair market value of the Common Stock subject to such ISO on
the date of grant.
 
                                       C-2
<PAGE>   54
 
     The fair market value of a share of Common Stock on any day shall be (a) if
the principal market for the Common Stock is a national securities exchange, the
average of the highest and lowest sales prices per share of Common Stock on such
day as reported by such exchange or on a composite tape reflecting transactions
on such exchange, (b) if the principal market for the Common Stock is not a
national securities exchange and the Common Stock is quoted on The Nasdaq Stock
Market ("Nasdaq"), and (i) if actual sales price information is available with
respect to the Common Stock, the average of the highest and lowest sales prices
per share of Common Stock on such day on Nasdaq, or (ii) if such information is
not available, the average of the highest bid and lowest asked prices per share
of Common Stock on such day on Nasdaq or (c) if the principal market for the
Common Stock is not a national securities exchange and the Common Stock is not
quoted on Nasdaq, the average of the highest bid and lowest asked prices per
share of Common Stock on such day as reported on the OTC Bulletin Board Service
or by National Quotation Bureau, Incorporated or a comparable service; provided,
however, that if clauses (a), (b) and (c) of this Paragraph are all
inapplicable, or if no trades have been made or no quotes are available for such
day, the fair market value of the Common Stock shall be determined by the Board
by any method consistent with applicable regulations adopted by the Treasury
Department relating to stock options.
 
6.  Term.
 
     The term of each option granted pursuant to the Plan shall be such term as
is established by the Committee, in its sole discretion; provided, however, that
the term of each ISO granted pursuant to the Plan shall be for a period not
exceeding 10 years from the date of grant thereof; and further, provided, that
if, at the time an ISO is granted, the optionee owns (or is deemed to own under
Section 424(d) of the Code) stock possessing more than 10% of the total combined
voting power of all classes of stock of the Company, of any of its Subsidiaries
or of a Parent, the term of the ISO shall be for a period not exceeding five
years from the date of grant. Options shall be subject to earlier termination as
hereinafter provided.
 
7.  Exercise; Adjustment of Shares Subject to Options.
 
     Options granted hereunder shall vest and become exerciseable as set forth
in the Contract in respect thereof.
 
     An option (or any part or installment thereof), to the extent then
exercisable, shall be exercised by giving written notice to the Company (in
advance as determined by the Committee) at its principal office stating which
option is being exercised, specifying the number of shares of Common Stock as to
which such option is being exercised and accompanied by payment in full of the
aggregate exercise price therefor (or the amount due on exercise if the Contract
permits installment payments) (a) in cash or by certified check or (b) if the
applicable Contract permits, with previously acquired shares of Common Stock
having an aggregate fair market value on the date of exercise (determined in
accordance with Paragraph 5) equal to the aggregate exercise price of all
options being exercised, or with any combination of cash, certified check or
shares of Common Stock having such value. The Company shall not be required to
issue any shares of Common Stock pursuant to any such option until all required
payments, including any required withholding, have been made.
 
     Notwithstanding the foregoing, the Committee may, in its sole discretion,
permit payment of the exercise price of an option by delivery by the optionee of
a properly executed notice, together with a copy of his irrevocable instructions
to a broker acceptable to the Committee to deliver promptly to the Company the
amount of sale or loan proceeds sufficient to pay such exercise price. In
connection therewith, the Company may enter into agreements for coordinated
procedures with one or more brokerage firms.
 
     A person entitled to receive Common Stock upon the exercise of an option
shall not have the rights of a stockholder with respect to such shares of Common
Stock until the date of issuance of a stock certificate to him for such shares;
provided, however, that until such stock certificate is issued, any optionee
using previously acquired shares of Common Stock in payment of an option
exercise price shall continue to have the rights of a stockholder with respect
to such previously acquired shares.
 
     In no case may a fraction of a share of Common Stock be purchased or issued
under the Plan.
 
                                       C-3

8.  Termination of Relationship.
 
     Except as may otherwise be expressly provided in the applicable Contract,
any optionee whose relationship with the Company, its Parent and Subsidiaries as
an employee or a consultant (a "Relationship") has terminated for any reason
(other than as a result of the death or Disability of the optionee) may exercise
such option, to the extent exercisable on the date of such termination, at any
time during the 30 days commencing six months after the date of such
termination, but not thereafter. Notwithstanding the foregoing, if such
Relationship is terminated (a) for cause, or (b) if at any time during the first
six months after termination of the Relationship the optionee shall be directly
or indirectly employed by, associated with, or affiliated with, a chain of
automotive after market stores which in the Board of Directors' judgment is a
competitor of the Company, such optionee shall have no rights to exercise such
option.
 
     For the purposes of the Plan, an employment relationship shall be deemed to
exist between an individual and a corporation if, at the time of the
determination, the individual was an employee of such corporation for purposes
of Section 422(a) of the Code. As a result, an individual on military, sick
leave or other bona fide leave of absence shall continue to be considered an
employee for purposes of the Plan during such leave if the period of the leave
does not exceed 90 days, or, if longer, so long as the individual's right to
reemployment with the Company (or a related corporation) is guaranteed either by
statute or by contract. If the period of leave exceeds 90 days and the
individual's right to reemployment is not guaranteed by statute or by contract,
the employment relationship shall be deemed to have terminated on the 91st day
of such leave.
 
     Except as may otherwise be expressly provided in the applicable Contract,
options granted under the Plan shall not be affected by any change in the status
of the optionee so long as the optionee continues to be an employee of, or a
consultant to, the Company, or any of its Subsidiaries or a Parent (regardless
of having changed from one to the other or having been transferred from one
corporation to another).
 
     Nothing in the Plan or in any option granted under the Plan shall confer on
any optionee any right to continue in the employ of, or as a consultant to, the
Company, any of its Subsidiaries or a Parent, or interfere in any way with any
right of the Company, any of its Subsidiaries or a Parent to terminate the
optionee's relationship at any time for any reason whatsoever without liability
to the Company, its Subsidiaries or Parent.
 
     For purposes of this Plan, "cause" shall mean fraud or embezzlement by the
optionee, gross negligence by the optionee in the performance or nonperformance
of his duties for the Company, its Subsidiaries or Parent, or the optionee's
material failure or refusal to perform his duties at any time as an employee of
or consultant to the Company, a Subsidiary or Parent.
 
9.  Death or Disability of an Optionee.
 
     Except as may otherwise be expressly provided in the applicable Contract,
if an optionee dies while he or she is an employee of, or consultant to, the
Company, any of its Subsidiaries or a Parent, or his or her Relationship
terminates by reason of his or her Disability, the option may be exercised, to
the extent exercisable on the date of his or her death or in the event of his or
her Disability, upon the effective date of such termination, by his or her Legal
Representative (as defined in Paragraph 20) at any time within 90 days after the
date of death or the effective date of such termination, but not thereafter.
 
10.  Compliance with Securities Laws.
 
     The Committee may require, in its sole discretion, as a condition to any
option being exercisable that either (a) a Registration Statement under the
Securities Act of 1933, as amended (the "Securities Act"), with respect to the
shares of Common Stock to be issued upon such exercise shall be effective and
current at the time of exercise, or (b) there is an exemption from registration
under the Securities Act for the issuance of the shares of Common Stock upon
such exercise. Nothing herein shall be construed as requiring the Company to
register shares subject to any option under the Securities Act or to keep any
Registration Statement effective or current.
 
     The Committee may require, in its sole discretion, as a condition to the
exercise of any option that the optionee execute and deliver to the Company his
representations and warranties, in form, substance and scope satisfactory to the
Committee, which the Committee determines are necessary or convenient to
facilitate the
                                       C-4
<PAGE>   56
 
perfection of an exemption from the registration requirements of the Securities
Act, applicable state securities laws or other legal requirement, including
without limitation that (a) the shares of Common Stock to be issued upon the
exercise of the option are being acquired by the optionee for his own account,
for investment only and not with a view to the resale or distribution thereof,
and (b) any subsequent resale or distribution of shares of Common Stock by such
optionee will be made only pursuant to (i) a Registration Statement under the
Securities Act which is effective and current with respect to the shares of
Common Stock being sold, or (ii) a specific exemption from the registration
requirements of the Securities Act, but in claiming such exemption, the optionee
shall prior to any offer of sale or sale of such shares of Common Stock, provide
the Company with a favorable written opinion of counsel satisfactory to the
Company, in form, substance and scope satisfactory to the Company, as to the
applicability of such exemption to the proposed sale or distribution.
 
     In addition, if at any time the Committee shall determine, in its sole
discretion, that the listing or qualification of the shares of Common Stock
subject to such option on any securities exchange, Nasdaq or under any
applicable law, or the consent or approval of any governmental authority or
regulatory body, is necessary or desirable as a condition to, or in connection
with, the granting of an option or the issue of shares of Common Stock
thereunder, such option may not be exercised in whole or in part unless such
listing, qualification, consent or approval shall have been effected or obtained
free of any conditions not acceptable to the Committee.
 
     No Optionee shall transfer any shares of Common Stock, except pursuant to
an effective registration statement under the Securities Act or pursuant to Rule
144 under the Securities Act.
 
11.  Stock Option Contracts.
 
     Each option shall be evidenced by an appropriate Contract which shall be
duly executed by the Company and the optionee, and shall contain such terms,
provisions and conditions not inconsistent herewith as may be determined by the
Committee.
 
12.  Adjustments upon Changes in Common Stock.
 
     Notwithstanding any other provision of the Plan, in the event of a stock
dividend, spin-off, split-up, combination, reclassification, recapitalization,
merger in which the Company is the surviving corporation, or exchange of shares
or the like which results in a change in the number or kind of shares of Common
Stock which are authorized for issuance or which are outstanding immediately
prior to such event, the aggregate number and kind of shares subject to the
Plan, the aggregate number and kind of shares subject to each outstanding option
and the exercise price thereof, and the 162(m) Maximum shall be adjusted
accordingly by the Board of Directors, whose determination shall be conclusive
and binding on all parties.
 
13.  Certain Sales of the Company.
 
     a) In the event that, at any time during the term of an option, there shall
be (i) a sale of shares of capital stock by one or more stockholders, which
results in shares of capital stock having an aggregate of 80% of the voting
power of all outstanding shares of capital stock being owned, directly or
indirectly, by one or more related persons, or (ii) the sale of 80% or more of
the Company's assets in any one transaction or series of related transactions,
in either case to parties which at the time of such sales were not stockholders
or affiliates of any stockholder of the Company (collectively, "Sales" and the
final such sale being the "Triggering Sale"), the portion of such option which
remains unvested at the time of the Triggering Sale shall vest upon the
occurrence of the Triggering Sale.
 
     b) Notwithstanding anything to the contrary contained herein, until an
optionee is notified in writing by the Company that all provisions of the
Stockholders' Agreement, dated as of October 30, 1996, among the Company and
certain of its stockholders (the "Stockholders' Agreement") relating to the
purchase and sale of the Company's securities (other than in a public offering)
have terminated, all shares of Common Stock
 
                                       C-5
<PAGE>   57
 
issued upon the exercise of options granted hereunder shall be subject to the
following restrictions and have the following rights:
 
          (i) If, pursuant to the terms of the Stockholders' Agreement in
     connection with an arm's-length sale to an unaffiliated third party
     pursuant to a written offer to purchase at least all of the securities of
     the Company held by the stockholders party to the Stockholders' Agreement,
     certain of the stockholders party to the Stockholders' Agreement (the
     "Moving Group") have the right to require the other holders of securities
     bound by the terms of the Stockholders' Agreement (the "Selling
     Stockholders") to sell all of their equity securities of the Company either
     to the third party or to the Moving Group and/or the Company (the
     "Purchaser") for consideration per share having at least the same value as
     the consideration proposed to be paid by the third party, the Moving Group
     shall also have the right to require each optionee to sell, and each
     optionee shall sell and deliver free and clear of all liens, claims and
     encumbrances, all of each optionee's Common Stock in the same transaction
     to the Purchaser, provided, however, that such optionee receives the same
     terms, including, without limitation, the same consideration per share of
     Common Stock, as is received in such transactions by the Selling
     Stockholders.
 
          (ii) If, pursuant to the terms of the Stockholders' Agreement in
     connection with a proposed sale of more than 25% of the outstanding equity
     securities of the Company by certain of the stockholders party to the
     Stockholders' Agreement (the "Transferring Stockholders"), such sale by
     such Transferring Stockholders cannot be consummated unless (y) prior to
     such sale each of the other stockholders party to the Stockholders'
     Agreement (the "Other Stockholders") and the Company shall have been given
     notice of the proposed transaction, which notice shall specify the number
     of shares that the Transferring Stockholders desire to sell, the identity
     of the prospective purchaser (the "Buyer"), and the proposed terms thereof
     and shall also include a copy of the written offer from the Buyer, and (z)
     each of the Other Stockholders shall have been provided a firm irrevocable
     right, which right shall be exercisable by written notice (which shall
     specify the number of shares (up to the total number of shares held by the
     Transferring Stockholders) that the Other Stockholders desire to sell)
     within 60 days after giving notice to the Other Stockholders, to sell to
     the Buyer, at the same time and upon the same terms and conditions offered
     to the Transferring Stockholders by the Buyer, the number of shares of
     Common Stock of the Other Stockholders (the "Proportionate Amount") that
     bears the same ratio to the total number of shares of Common Stock held by
     the Other Stockholders as the total number of shares of Common Stock
     proposed to be sold by the Transferring Stockholders to the Buyer bears to
     the total number of shares of Common Stock held by all of the Transferring
     Stockholders, the Company will not register the transfer of securities from
     the Transferring Stockholders to the Buyer unless the Transferring
     Stockholders and the Buyer shall have extended to each optionee the rights
     described above which are required to be extended to Other Stockholders in
     connection with such a sale.
 
14.  Amendments and Termination of the Plan.
 
     The Plan was adopted by the Board of Directors on April 30, 1999, subject
to the approval of the Company's stockholders. No option may be granted under
the Plan after April 30, 2009. The Board of Directors, without further approval
of the Company's stockholders, may at any time suspend or terminate the Plan, in
whole or in part, or amend it from time to time in such respects as it may deem
advisable, including, without limitation, in order that ISOs granted hereunder
meet the requirements for "incentive stock options" under the Code, to comply
with the provisions of Rule 16b-3, Section 162(m) of the Code, or any change in
applicable law, regulations, rulings or interpretations of administrative
agencies; provided, however, that no amendment shall be effective without the
prior or subsequent stockholder approval required under applicable law or the
Code which would (a) except as contemplated in Paragraph 12, increase the
maximum number of shares of Common Stock for which options may be granted under
the Plan or the 162(m) Maximum, or (b) change the eligibility requirements to
receive options hereunder. No termination, suspension or amendment of the Plan
shall, without the consent of the holder of an existing and outstanding option
affected thereby, adversely affect his rights under such option. The power of
the Committee to construe and administer any options granted under the Plan
prior to the termination or suspension of the Plan nevertheless shall continue
after such termination or during such suspension.
 
                                       C-6
<PAGE>   58
 
15.  Non-transferability of Options.
 
     No option granted under the Plan shall be transferable otherwise than by
will or the laws of descent and distribution, and options may be exercised,
during the lifetime of the optionee, only by the optionee or his Legal
Representatives. Except to the extent provided above, options may not be
assigned, transferred, pledged, hypothecated or disposed of in any way (whether
by operation of law or otherwise) and shall not be subject to execution,
attachment or similar process, and any such attempted assignment, transfer,
pledge, hypothecation or disposition shall be null and void ab initio and of no
force or effect.
 
16.  Withholding Taxes.
 
     The Company may withhold (a) cash, (b) subject to any limitations under
Rule 16b-3, shares of Common Stock to be issued with respect thereto having an
aggregate fair market value on the exercise date (determined in accordance with
Paragraph 5), or (c) any combination thereof, in an amount equal to the amount
which the Committee determines is necessary to satisfy the obligation of the
Company, a Subsidiary or a Parent to withhold Federal, state and local income
taxes or other amounts incurred by reason of the grant or exercise of an option,
its disposition, or the disposition of the underlying shares of Common Stock.
Alternatively, the Company may require the holder to pay to the Company such
amount, in cash, promptly upon demand.
 
17.  Legends; Payment of Expenses.
 
     The Company may endorse such legend or legends upon the certificates for
shares of Common Stock issued upon exercise of an option under the Plan and may
issue such "stop transfer" instructions to its transfer agent in respect of such
shares as it determines, in its discretion, to be necessary or appropriate to
(a) prevent a violation of, or to perfect an exemption from, the registration
requirements of the Securities Act and any applicable state securities laws, (b)
implement the provisions of the Plan or any agreement between the Company and
the optionee with respect to such shares of Common Stock, or (c) permit the

          e) Subsidiary.  The term "Subsidiary" shall have the same definition
     as "subsidiary corporation" in Section 424(f) of the Code.
 
21.  Governing Law; Construction.
 
     The Plan, such options as may be granted hereunder and all related matters
shall be governed by, and construed in accordance with, the laws of the State of
Delaware, without regard to conflict of law provisions.

term stated in either the singular or plural shall include the singular and
plural, and any term stated in the masculine, feminine or neuter gender shall
include the masculine, feminine and neuter.

or any Contract shall not affect the validity, legality or enforceability of any
other provision, all of which shall be valid, legal and enforceable to the
fullest extent permitted by applicable law.
 
23.  Board and Stockholder Approval.
 
     The Plan was originally approved by the Company's Board of Directors as of
April 30, 1999, and by the affirmative vote of a majority of the Company's
stockholders at the Company's 1999 Annual Meeting of Stockholders on June 8,
1999.
