SEVERANCE AND RETENTION AGREEMENT

     SEVERANCE AND RETENTION AGREEMENT (this “Agreement”) dated as of March 31, 2008, by and between CSK Auto, Inc., an Arizona corporation (the “Company”), and [<EXECUTIVE>] the “Executive”).

RECITALS

     The Company considers it essential and in the best interest of its stockholders to foster the continuous employment of key management personnel. The Company further recognizes that, as in the case of many publicly held corporations, the possibility of a change of control of the Company may exist and that such possibility, and the uncertainty and questions which it may raise among management, may create concerns for, and the distraction of, management personnel and may even result in departures which might have otherwise not have taken place, all to the detriment of the Company and its stockholders. The Company now desires to take steps to reinforce and encourage the continued attention and dedication of members of the Company’s management, including the Executive, to their assigned duties without distraction in the face of potentially disturbing circumstances arising from the possibility of a Change of Control (as defined below) of the Company.

AGREEMENT

     1. Definitions

          1.1 An “Affiliate” of the Company is an entity controlling, controlled by or under common control with the Company as defined in Rule 405 of the Securities and Exchange Commission under the Securities Act of 1933, as amended.

          1.4 A “Change of Control” shall be deemed to have taken place if, after the date hereof:

     (a) any person, corporation, or other entity or group, including any “group” as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, other than any employee benefit plan then maintained by CSK Auto Corporation (“Parent”), becomes the beneficial owner of shares of Parent having 50% or more of the total number of votes that may be cast for the election of directors of Parent (including any shares owned by such beneficial owner or members of its “group” as of the date hereof);

     (b) as the result of, or in connection with, any contested election for the Board of Directors of Parent, or any tender or exchange offer, merger or other business combination or sale of assets, or any combination of the foregoing (a “Transaction”), the persons who were directors of Parent before the Transaction shall cease to constitute a majority of the Board of Directors of Parent or any successor to Parent or its assets;

     (c) at any time Parent shall consolidate or merge with any other Person and Parent shall not be the continuing or surviving corporation, or any Person shall consolidate or merge with Parent and Parent shall be the continuing or surviving corporation, and in connection therewith, all or part of the outstanding Parent stock shall be changed into or exchanged for stock or other securities of any other Person or cash or any other property;

          1.6 The Executive shall have “Good Reason” to terminate employment if, without the Executive’s consent:

     (a) the Executive’s duties, responsibilities or authority are materially reduced or diminished (provided, however, that neither (i) a change in the Executive’s reporting relationships, nor (ii) an adjustment in the nature of the Executive’s duties and responsibilities that, in either case, does not remove from him the authority with respect to the Company’s functional area, employees or products and services that the Executive had immediately prior to such change or adjustment shall constitute Good Reason);

     (b) the Executive’s compensation or benefits are reduced;

     (c) the Company reduces the potential earnings of the Executive under any performance-based bonus or incentive plan of the Company;

     (d) the Company requires that the Executive’s employment be based at a location outside a 50 mile radius from the location of the Executive’s employment location as of the date hereof or the Executive’s employment location immediately prior to a Change of Control Date, as the case may be;

     (f) the Company breaches any of the material provisions of this Agreement or the Executive’s employment agreement or offer letter (if any); or

     (g) if applicable, the Company breaches any of the provisions of the Letter Agreement (the “Letter Agreement”), dated as of March 31, 2008, between the Company and the Executive regarding the Executive’s commuting arrangements and related agreement by the Company to pay or reimburse the Executive for travel, living and/or relocation expenses as set forth therein.

          Notwithstanding the foregoing, none of the events referred to in (a) through (f) above shall constitute Good Reason unless the Executive gives written notice to the Company of his election to terminate his employment for such reason within 15 days after he becomes aware of the existence of facts or circumstances constituting Good Reason; provided, however, that with respect to the events referred to in (a) above that occur upon or directly as a result of a Change of Control, this notice period shall be extended until 90 days following the occurrence of the Change of Control. Such notice shall set forth in reasonable detail the facts and circumstances constituting the Good Reason and, if the Good Reason is a curable condition (in the good faith determination of the Company), shall provide the Company with 30 days to cure such condition. The notice shall also specify the date when the termination of employment is to become effective (if the Good Reason is not curable or is curable, but not cured within the 30 days), which date shall be not less than 45 days and not more than 90 days from the date the notice is given; provided, however, that after receiving such notice, the Company shall be permitted to terminate the Executive’s employment prior to the termination date specified by Executive without payment of additional compensation to the Executive (provided, however, that the Company shall still be obligated for payment of the severance and other benefits set forth in this Agreement in accordance with the terms and conditions herein).

     (ii) accrued and unused vacation;

     (iii) reimbursement for properly incurred business expenses, including, but not limited to, expenses incurred pursuant to the Letter Agreement, if any;

     (f) If the Company determines (i) that on the date the Executive’s employment with the Company terminates or at such other time that the Company determines to be relevant, the Executive is a “specified employee” (as such term is defined under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”)) of the Company and (ii) that payment of the amounts set forth in Section 3.2(a) or other such payments provided hereunder would be considered “deferred compensation” under Section 409A of the Code subject to the additional tax under Section 409A(a)(1)(B) of the Code if provided at the time otherwise required under this Agreement, then commencement of such payments shall be delayed until the earlier of

(A) the Executive’s death or (B) the date that is six months following the Executive’s “separation from service” with the Company (within the meaning of Section 409A of the Code). Any installment payments that are delayed pursuant to the preceding sentence shall be paid in lump sum on the first date such payments become payable pursuant to the preceding sentence, after which time the remainder of the payments shall be made in equal monthly installments pursuant to Section 3.2.

     4. Standard Severance Benefits

          4.1 Eligibility for Standard Severance Benefits. If the Executive’s employment with the Company is terminated (i) by the Company without Cause or (ii) by the Executive for Good Reason, in each case other than during the Post Change of Control Period, the Executive shall be eligible for the benefits described in Section 4.2 (the “Standard Severance Benefits”).

     5. Release. Notwithstanding anything in this Agreement to the contrary, neither the Retention Bonus, the Change of Control Severance Benefits nor the Standard Severance Benefits shall be payable to the Executive pursuant to this Agreement unless and until the eighth (8th) day after the Executive executes (and does not subsequently revoke), in each case, a general release in the form of Exhibit A attached hereto (the “Release”).

     6. Tax Indemnity Payments.

     (a) Notwithstanding anything in this Severance Agreement or any other agreement between the Executive and the Company to the contrary, in the event that it shall be determined that the aggregate payments or distributions by the Company, any purchaser, successor, or assign thereof, or any of its or their affiliates to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms hereof, the LTIP or otherwise, but determined without regard to any additional payments required under this Section 6 (each a “Payment”), constitute “parachute payments” (as such term is defined under Section 280G of the Code or any successor provision, and the regulations promulgated thereunder (collectively, “Section 280G”)) subject to the excise tax imposed by Section 4999 of the Code or any successor provision (collectively, “Section 4999”) or any interest or penalties with respect to such excise tax (the total excise tax, together with any interest and penalties, are hereinafter collectively referred to as the “Excise Tax”)), then the Executive shall be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount such that after payment by the Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including, without limitation, any federal, state or local income and self-employment taxes and Excise Tax (and any interest and penalties imposed with respect to any such taxes) imposed upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments.

     (b) Subject to the provisions of Section 6(c) hereof, all determinations required to be made under this Section 6, including whether and when a Gross-Up Payment is required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by the Company’s public accounting firm (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Company and the Executive within fifteen (15) business days of the receipt of notice from the Executive that there has been a Payment, or such earlier time as is requested by the Company. All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to this Section 6, shall be paid by the Company to the Executive within five (5) business days of the receipt of the Accounting Firm’s determination (it being understood, however, that the Gross Up Payment may, if permitted by law, be paid directly to the applicable taxing authorities). If the Accounting Firm determines that no Excise Tax is payable by the Executive, it shall furnish the Executive with a written report detailing its determination. Any determination by the Accounting Firm shall be binding upon the Company and the Executive. As a result of the uncertainty in the application of Section 4999 at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company should have been made by the

Company (an “Underpayment”), or that Gross-Up Payments will have been made by the Company which should not have been made (an “Overpayment”), consistent with the calculations required to be made hereunder. In either such event, the Accounting Firm shall determine the amount of the Underpayment or Overpayment that has occurred. In the event that the Company exhausts its remedies pursuant to Section 6(c) and the Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive. In the case of an Overpayment, the Executive shall, at the direction and expense of the Company, take such steps as are reasonably necessary (including, if reasonable, the filing of returns and claims for refund), and otherwise reasonably cooperate with the Company to correct such Overpayment (or, if retained by the Executive, at his own expense to repay such Overpayment); provided, however, that (i) in the event of an Overpayment actually paid to the IRS or other relevant taxing authority, and provided that the Executive uses his best efforts to seek a refund of any such Overpayment, the Executive shall not be obligated to return to the Company an amount greater than the net after-tax portion of the Overpayment that he has retained or has recovered as a refund from the applicable taxing authorities and (ii) this provision shall be interpreted in a manner consistent with the intent of Section 6(a) hereof to make the Executive whole, on an after-tax basis, from the application of Section 4999.

     (c) The Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require a payment by the Company, or a change in the amount of the payment by the Company of, the Gross-Up Payment. Such notification shall be given as soon as practicable after the Executive is informed in writing of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid; provided that the failure to give any notice pursuant to this Section 6(c) shall not impair the Executive’s rights under this Section 6 except to the extent the Company is materially prejudiced thereby. The Executive shall not pay such claim prior to the expiration of the 30-day period following the date on which the Executive gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Executive in writing prior to the expiration of such period that it desires to contest such claim, the Executive shall:

     (i) give the Company any information reasonably requested by the Company relating to such claim,

     (ii) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company,

     (iii) cooperate with the Company in good faith in order effectively to contest such claim, and

     (iv) permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold the Executive harmless, on an after-tax basis, for any Excise Tax or income, self-employment or other tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses.

Without limitation on the foregoing provisions of this Section 6(c), the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct the Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and the Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided further, that if the Company directs the Executive to pay such claim and sue for a refund, the Company shall advance the amount of such payment to the Executive on an interest-free basis and shall indemnify and hold the Executive harmless, on an after-tax basis, from any Excise Tax or income, self-employment or other tax (including interest or penalties with respect to any such taxes) imposed with respect to such advance or with respect to any imputed income with respect to such advance; and provided further, that any extension of the statute of limitations relating to payment of taxes for the taxable year of the Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company’s control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and the Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.

If, after the receipt by the Executive of any Overpayment or any amount advanced by the Company pursuant to Section 6(c) hereof, the Executive becomes entitled to receive, and receives, any refund with respect to such claim, the Executive shall (subject to the Company’s complying with the requirements of Section 6(c) hereof) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by the Executive of an amount advanced by the Company pursuant to Section 6(c), a determination is made that the Executive shall not be entitled to any refund with respect to such claim and the Company does not notify the Executive in writing of its intent to contest such denial of refund prior to the expiration of ninety (90) days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid.

     7. Restrictive Covenants.

          7.1 Confidentiality. The Executive understands and acknowledges that during the Executive’s employment with the Company, the Executive has had and will have access to

and has learned and will learn (i) information proprietary to the Company and its Affiliates that concerns the operation and methodology of the businesses conducted by the Company and its Affiliates and as the same are hereafter conducted by the Company and its Affiliates (the “Business”) or (ii) other information proprietary to the Company and its Affiliates, including, without limitation, trade secrets, processes, patent and trademark applications, product development, price, customer and supply lists, pricing and marketing plans, policies and strategies, details of client and consultant contracts, operations methods, product development techniques, business acquisition plans, new personnel acquisition plans and all other confidential information with respect to the Business (collectively, “Proprietary Information”). The Executive agrees that, from and after the date hereof, the Executive will keep confidential and will not disclose directly or indirectly any such Proprietary Information to any third party, except as required to fulfill the Executive’s duties as an Executive of the Company, and will not misuse, misappropriate or exploit such Proprietary Information in any way. The restrictions contained herein shall not apply to any information which (a) was already available to the public at the time of disclosure, or subsequently becomes available to the public otherwise than by breach of this Agreement, or (b) was disclosed due to a requirement of law, provided that the Executive shall have given prompt notice of such requirement to the Company to enable the Company to seek an appropriate protective order with respect to such disclosure. Upon any termination of the employment of the Executive, the Executive shall promptly return to the Company and its Affiliates all documents, computer disks, records, notebooks and similar repositories of any Proprietary Information in the Executive’s possession, including copies thereof.

          7.2 Agreement Not to Compete/Non-Solicitation.

     (a) During the twelve (12) month period following the Executive’s termination of employment under circumstances entitling the Executive to either the Change of Control Severance Benefits or the Standard Severance Benefits, as applicable (the “Non-Compete Period”), the Executive shall not become engaged in a managerial or executive capacity for, or consultant to, Auto Zone, Inc., The Pep Boys — Manny, Moe & Jack, O’Reilly Automotive, Inc., or Advance Stores Company, Incorporated (the “Competitors”). Notwithstanding the foregoing, in the event of a Change of Control that results in the Company (or its assets or business) being acquired or merging with a Competitor (or subsidiary thereof), the preceding sentence shall have no effect with respect to such Competitor.

     (b) During the Non-Compete Period, the Executive shall not, directly or indirectly, hire or attempt to hire any employee of the Company.

     (c) During the Non-Compete Period, the Executive shall not, directly or indirectly, call on or solicit any person, firm, corporation, business or other entity who or which is, or within two years prior to the Non-Compete Period had been, a customer of the Company or any Affiliate of the Company.

          7.3 Remedies. The Executive acknowledges and agrees that damages for a breach or threatened breach of any of the covenants set forth in this Section 7 will be difficult to determine and will not afford a full and adequate remedy, and therefore agrees that the Company, in addition to seeking actual damages in connection therewith, may seek specific

enforcement of any such covenant in any court of competent jurisdiction, including, without limitation, by the issuance of a temporary or permanent injunction. In addition, the Company may terminate the payment of any remaining Change of Control Severance Benefits or Standard Severance Benefits in the event of a breach or threatened breach of any of the covenants set forth in this Section 7.

     8. Waiver of Other Severance Benefits. The Change of Control Severance Benefits and Standard Severance Benefits payable pursuant to this Agreement are in lieu of any and all other severance benefits that may otherwise be payable to the Executive upon termination of his or her employment for any reason (including, without limitation, any benefits to which the Executive might otherwise have been entitled under the Stockholders Agreement, dated October 30, 1996, among the stockholders named therein and the Company, any employment agreement and any letter agreements to which the Executive is a party (collectively, “Contractual Benefits”), except those benefits which are to be made available to the Executive as required by applicable law and as provided herein, and Executive hereby waives all such Contractual Benefits in exchange for the Company’s agreement to make the payments to be made hereunder. For the avoidance of doubt, nothing in this Section 8 shall be deemed to waive any rights the Executive may have under the Company’s long-term and/or equity incentive plans, tax-qualified retirement plans or nonqualified deferred compensation plans.

     9. Assumption of Agreement. The Company will require any successor (whether by purchase of assets, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform all of the obligations of the Company under this Agreement (including the obligation to cause any subsequent successor to also assume the obligations of this Agreement) unless such assumption occurs by operation of law.

     11. This Release shall be construed, interpreted and applied in accordance with the law of the State of Arizona (other than conflict of laws principles).
