            Eleven Madison Avenue,
          New York, N.Y. 10010-3629


Dear Sirs:

         1. Introductory. CSK Auto, Inc., an Arizona corporation (the
"COMPANY"), proposes, subject to the terms and conditions stated herein, to
issue and sell to Credit Suisse First Boston Corporation, J.P. Morgan Securities
Inc. and UBS Warburg LLC (the "PURCHASERS") U.S. $280,000,000 principal amount
of its 12% Senior Notes due 2006 ("OFFERED SECURITIES") to be issued under an
indenture (the "INDENTURE"), dated as of the Closing Date (as defined below),
between the Company, the guarantors named therein (each, a "GUARANTOR," and
collectively, the "GUARANTORS") and The Bank of New York, as trustee (the
"TRUSTEE"). The Offered Securities will be irrevocably and unconditionally
guaranteed (the "GUARANTEES") as to payment of principal, premium, if any,
interest and Liquidated Damages (as defined in the Indenture), if any, on a
senior basis, jointly and severally by each of the Guarantors. The United States
Securities Act of 1933 is herein referred to as the "SECURITIES ACT."

         Holders (including subsequent transferees) of the Offered Securities
will have the registration rights set forth in the registration rights agreement
(the "REGISTRATION RIGHTS AGREEMENT"), to be dated the Closing Date, in
substantially the form of Exhibit I hereto, for so long as such Offered
Securities constitute "TRANSFER RESTRICTED SECURITIES" (as defined in the
Registration Rights Agreement). Pursuant to the Registration Rights Agreement,
the Company and the Guarantors will agree to file with the Securities and
Exchange Commission (the "COMMISSION") under the circumstances set forth
therein, (i) a registration statement under the Securities Act (the "EXCHANGE
OFFER REGISTRATION STATEMENT") relating to the Company's 12% Senior Notes due
2006 in a like aggregate principal amount as the Company issued under the
Indenture, identical in all material respects to the Offered Securities and
registered under the Securities Act (the "EXCHANGE SECURITIES"), with guarantees
endorsed thereon by the Guarantors to be offered in exchange for the Offered
Securities (such offer to exchange being referred to as the "EXCHANGE OFFER")
and the Guarantees thereof and (ii) a shelf registration statement pursuant to
Rule 415 under the Securities Act (the "SHELF REGISTRATION STATEMENT" and,
together with the Exchange Offer Registration Statement, the "REGISTRATION
STATEMENTS") relating to the resale by certain holders of the Offered Securities
and to use its best efforts to cause such Registration Statements to be declared
and remain effective and usable for the periods specified in the Registration
Rights Agreement and to consummate the Exchange Offer. The Offered Securities
and the Exchange Securities are referred to collectively as the "SECURITIES".

         The Company hereby agrees with the Purchasers as follows:

         2. Representations and Warranties of the Company and the Guarantors.
The Company and the Guarantors represent and warrant to, and agree with, the
several Purchasers that:

                  (a) A preliminary offering circular and an offering circular
         relating to the Offered Securities to be offered by the Purchasers have
         been prepared by the Company. Such preliminary offering circular (the
         "PRELIMINARY OFFERING CIRCULAR") and offering circular (the "OFFERING
         CIRCULAR"), as supplemented as of the date of this Agreement, together
         with any other document approved by the Company for use in connection
         with the contemplated resale of the Offered Securities are hereinafter
         collectively referred to as the "OFFERING DOCUMENT". The Preliminary
         Offering Circular as of its date did not, and the Offering Circular on
         the date of this Agreement, does not include any untrue statement of a
         material fact or omit to state any material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading. The preceding sentence does not
         apply to statements in or omissions from any Offering Document based
         upon written information relating to any Purchaser furnished to the
         Company by any Purchaser through Credit Suisse First Boston Corporation
         ("CSFBC") specifically for use therein, it being understood and agreed
         that the only such information is that described as such in Section
         7(b) hereof. Except as disclosed in the Offering Document, on the date
         of this Agreement, the Annual Report on Form 10-K most recently filed
         with the Securities and Exchange Commission (the "COMMISSION") by the
         Company's parent company, CSK Auto Corporation ("CSK"), and all
         subsequent reports (collectively, the "EXCHANGE ACT REPORTS") which
         have been filed by CSK with the Commission or sent to stockholders
         pursuant to the Securities Exchange Act of 1934 (the "EXCHANGE ACT") do
         not include any untrue statement of a material fact or omit to state
         any material fact necessary to make the statements therein, in the
         light of the circumstances under which they were made, not misleading.
         Such documents, when they were filed with the Commission, conformed in
         all material respects to the requirements of the Exchange Act and the
         rules and regulations of the Commission thereunder.

                  (b) The Company has been duly incorporated and is an existing
         corporation in good standing under the laws of the State of Arizona,
         with power and authority (corporate and other) to own its properties
         and conduct its business as described in the Offering Document; and the
         Company is duly qualified to do business as a foreign corporation in
         good standing in all other jurisdictions in which its ownership or
         lease of property or the conduct of its business requires such
         qualification, except where the failure to be so qualified would not
         individually or in the aggregate have a material adverse effect on the
         condition (financial or other), business, properties or results of
         operations of the Company and the Guarantors taken as a whole
         ("MATERIAL ADVERSE EFFECT").

                  (c) All of the outstanding shares of capital stock of the
         Company have been duly authorized and validly issued and are fully paid
         and non-assessable.

                  (d) The entities listed on Schedule B hereto are the only
         subsidiaries, direct or indirect, of the Company. CSK and each
         subsidiary of the Company has been duly incorporated and is an existing
         corporation in good standing under the laws of the jurisdiction of its
         incorporation, with power and authority (corporate and other) to own
         its properties and conduct its business as described in the Offering
         Document; CSK and each subsidiary of the Company is duly qualified to
         do business as a foreign corporation in good standing in all other
         jurisdictions in which its ownership or lease of property or the
         conduct of its business requires such qualification, except where the
         failure to be so qualified would not individually or in the aggregate
         have a Material Adverse Effect; all of the issued and outstanding
         capital stock of CSK and each subsidiary of the Company has been duly
         authorized and validly issued and is fully paid and nonassessable; and
         the capital stock of each subsidiary owned by the Company, directly or
         through subsidiaries, is owned free from liens, encumbrances and
         defects. On the Closing Date, the Offered Securities will conform as to
         legal matters to the description thereof in the Offering Circular.

                  (e) The Indenture has been duly authorized by the Company and
         the Offered Securities have been duly authorized by the Company. When
         the Offered Securities are delivered and paid for

         been duly executed and delivered, such Offered Securities will have
         been duly executed, authenticated, issued and delivered by the Company
         and will conform to the description thereof contained in the Offering
         Document in all material respects and the Indenture and such Offered
         Securities will constitute valid and legally binding obligations of the
         Company, enforceable in accordance with their terms, subject to
         bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
         and similar laws of general applicability relating to or affecting
         creditors' rights and to general equity principles.

                  (f) The Indenture has been duly authorized by each Guarantor
         and the Guarantee to be endorsed on the Offered Securities by each
         Guarantor has been duly authorized by the applicable Guarantor. When
         the Offered Securities are delivered and paid for pursuant to this
         Agreement on the Closing Date, the Indenture will have been duly
         executed and delivered by each Guarantor, the Guarantee of each
         Guarantor endorsed thereon will have been duly executed, issued and
         delivered by such Guarantor and the Indenture and Guarantee will
         constitute valid and legally binding obligations of such Guarantor,
         enforceable in accordance with their terms, subject to bankruptcy,
         insolvency, fraudulent transfer, reorganization, moratorium and similar
         laws of general applicability relating to or affecting creditors'
         rights and to general equity principles.

                  (g) On the Closing Date, the Exchange Securities will have
         been duly authorized by the Company and the Guarantors; and when the
         Exchange Securities are issued, executed and authenticated in
         accordance with the terms of the Exchange Offer and the Indenture, the
         Exchange Securities will constitute valid and legally binding
         obligations of the Company and the Guarantors, enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles.

                  (h) The Guarantee to be endorsed on the Exchange Securities by
         each Guarantor has been duly authorized by such Guarantor; and, when
         issued, will have been duly executed and delivered by each such
         Guarantor and will conform to the description thereof contained in the
         Offering Document in all material respects. When the Exchange
         Securities have been issued, executed and authenticated in accordance
         with the terms of the Exchange Offer and the Indenture, the Guarantee
         of each Guarantor endorsed thereon will constitute valid and legally
         binding obligations of such Guarantor, enforceable in accordance with
         its terms, subject to bankruptcy, insolvency, fraudulent transfer,
         reorganization, moratorium and similar laws of general applicability
         relating to or affecting creditors' rights and to general equity
         principles.

         by the Company and each of the Guarantors and, on the Closing Date,
         will have been duly executed and delivered by the Company and each of
         the Guarantors. When the Registration Rights Agreement has been duly
         executed and delivered by the Company and the other parties thereto,
         the Registration Rights Agreement will be a valid and binding agreement
         of the Company and each of the Guarantors, enforceable against the
         Company and each Guarantor in accordance with its terms, subject to
         bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
         and similar laws of general applicability relating to or affecting
         creditors' rights and to general equity principles. On the Closing
         Date, the Registration Rights Agreement will conform as to legal
         matters to the description thereof in the Offering Circular in all
         material respects.

                  (j) Except as disclosed in the Offering Document, there are no
         contracts, agreements or understandings between the Company and any
         person that would give rise to a valid claim against the Company or any
         Purchaser for a brokerage commission, finder's fee or other like
         payment in connection with the transactions contemplated hereby.

                  (k) No consent, approval, authorization, or order of, or
         filing with, any governmental agency or body or any court is required

                  (x) The financial statements, together with the related
         schedules and notes, included or incorporated in the Offering Document
         present fairly the financial position of CSK, the Company and its

         statements and related schedules and notes have been prepared in

         Document provide a reasonable basis for presenting the significant
         effects directly attributable to the transactions or events described
         therein, the related pro forma adjustments give appropriate effect to

         financial statement amounts; and the other financial and statistical
         information and data set forth in the Offering Document are, in all
         material respects, accurately presented and, with respect to such

         development or event involving a prospective material adverse change,
         in the condition (financial or other), business, properties or results
         of operations of the Company, CSK and the subsidiaries of the Company
         taken as a whole, and, except as disclosed in or contemplated by the
         Offering Document, there has been no dividend or distribution of any
         kind declared, paid or made by CSK or the Company on any class of its
         capital stock.

                  (z) All indebtedness of the Company and the Guarantors that
         will be repaid with the proceeds of the issuance and sale of the
         Offered Securities was incurred, and the indebtedness represented by

         (as defined in Regulation D under the Securities Act) was used by the
         Company, the Guarantors or any of their respective representatives
         (other than the Purchasers, as to whom the Company and the Guarantors
         make no representation) in connection with the offer and sale of the
         Offered Securities and the Guarantees contemplated hereby, including,
         but not limited to, articles, notices or other communications published
         in any newspaper, magazine, or similar media or broadcast over
         television or radio, or any seminar or meeting whose attendees have

         immediately prior to the date hereof.

                  (jj) None of the Company, the Guarantors nor any of their
         respective affiliates or any person acting on its or their behalf
         (other than the Purchasers, as to whom the Company and the Guarantors
         make no representation) has engaged or will engage in any directed
         selling efforts within the meaning of Regulation S with respect to the

         that shall have resulted in any Offered Securities or Guarantees

         the Guarantors in respect of any material Tax liability for any Taxable
         period not finally determined are reasonably adequate to meet any
         assessments of Tax for any such period. For purposes of this Purchase
         Agreement, the term "Tax" and "Taxes" shall mean all Federal, state,
         local and foreign taxes, and other assessments of a similar nature
         (whether imposed directly or through withholding), including any
         interest, additions to tax, or penalties applicable thereto.

Purchasers, and the Purchasers agree, severally and not jointly, to purchase
from the Company the principal amount of Offered Securities set forth opposite

of Cede & Co., as nominee for DTC. The Company will deliver against payment of
the purchase price the Offered Securities to be purchased by each Purchaser
hereunder and to be offered and sold by each Purchaser in reliance on Rule 144A

Global Securities and the Restricted Global Securities shall be assigned
separate CUSIP numbers and shall include the legend regarding restrictions on

the termination of the restricted period (as defined in Regulation S) with
respect to the offering of the Offered Securities, interests in the Regulation S

as the case may be, except in the limited circumstances described in the
Offering Document.

                  not be offered or sold within the United States or to, or for
                  the account or benefit of, U.S. persons (i) as part of their
                  distribution at any time or (ii) otherwise until 40 days after

                  Act. Terms used above have the meanings given to them by

Regulation S.

                  (c) Each Purchaser severally agrees that it and each of its
         affiliates has not entered and will not enter into any contractual
         arrangement with respect to the distribution of the Offered Securities
         except for any such arrangements with the other Purchasers or
         affiliates of the other Purchasers with the prior written consent of
         the Company.

                  (d) Each Purchaser severally agrees that it and each of its
         affiliates will not offer or sell the Offered Securities in the United
         States by means of any form of general solicitation or general
         advertising within the meaning of Rule 502(c) under the Securities Act,
         including, but not limited to (i) any advertisement, article, notice or
         other communication published in any newspaper, magazine or similar
         media or broadcast over television or radio, or (ii) any seminar or
         meeting whose attendees have been invited by any general solicitation
         or general advertising. Each Purchaser severally agrees, with respect
         to resales made in reliance on Rule 144A of any of the Offered
         Securities, to deliver either with the confirmation of such resale or
         otherwise prior to settlement of such resale a notice to the effect
         that the resale of such Offered Securities has been made in reliance
         upon the exemption from the registration requirements of the Securities
         Act provided by Rule 144A.

                  (e) Each of the Purchasers severally represents and agrees
         that (i) it has not offered or sold and prior to the date six months
         after the date of issue of the Offered Securities will not offer or
         sell any Offered Securities to persons in the United Kingdom except to
         persons whose ordinary activities involve them in acquiring, holding,
         managing or disposing of investments (as principal or agent) for the
         purposes of their businesses or otherwise in circumstances which have

         United Kingdom within the meaning of the Public Offers of Securities
         Regulations 1995; (ii) it has complied and will comply with all
         applicable provisions of the Financial Services Act 1986 with respect

         or passed on and will only issue or pass on in the United Kingdom any
         document received by it in connection with the issue of the Offered
         Securities to a person who is of a kind described in Article 11(3) of
         the Financial Services Act 1986 (Investment Advertisements)
         (Exemptions) Order 1996 or is a person to whom such document may
         otherwise lawfully be issued or passed on.

         5. Certain Agreements of the Company and the Guarantors. The Company
and each of the Guarantors agrees with the several Purchasers that:


                                       9
<PAGE>
                  (a) The Company will advise CSFBC promptly of any proposal to
         amend or supplement the Offering Document and will not effect such
         amendment or supplementation without CSFBC's consent (which will not be
         unreasonably withheld) until the offering of the Offered Securities is
         complete. If, at any time prior to the completion of the resale of the
         Offered Securities by the Purchasers, any event occurs as a result of
         which the Offering Document as then amended or supplemented would
         include an untrue statement of a material fact or omit to state any
         material fact necessary in order to make the statements therein, in the
         light of the circumstances under which they were made, not misleading,
         or if it is necessary at any such time to amend or supplement the
         Offering Document to comply with any applicable law, the Company
         promptly will notify CSFBC of such event and promptly will prepare, at
         its own expense, an amendment or supplement which will correct such
         statement or omission or effect such compliance. Neither CSFBC's
         consent to, nor the Purchasers' delivery to offerees or investors of,
         any such amendment or supplement shall constitute a waiver of any of
         the conditions set forth in Section 6.

                  (b) The Company will furnish to CSFBC copies of any
         preliminary offering circular, the Offering Document and all amendments
         and supplements to such documents, in each case as soon as available
         and in such quantities as CSFBC requests, and the Company will furnish
         to CSFBC on the date hereof three copies of the Offering Document
         signed by a duly authorized officer of the Company. At any time when
         the Company is not subject to Section 13 or 15(d) of the Exchange Act,
         the Company will promptly furnish or cause to be furnished to CSFBC
         (and, upon request, to each of the other Purchasers) and, upon request
         of holders and prospective purchasers of the Offered Securities, to
         such holders and purchasers, copies of the information required to be
         delivered to holders and prospective purchasers of the Offered
         Securities pursuant to Rule 144A(d)(4) under the Securities Act (or any
         successor provision thereto) in order to permit compliance with Rule
         144A in connection with resales by such holders of the Offered
         Securities. The Company will pay the expenses of printing and
         distributing to the Purchasers all such documents.

                  (c) The Company and the Guarantors will arrange for the
         qualification of the Offered Securities and the Guarantees for sale and
         the determination of their eligibility for investment under the laws of
         such jurisdictions in the United States and Canada as CSFBC designates
         and will continue such qualifications in effect so long as required for
         the resale of the Offered Securities by the Purchasers, provided that
         the Company will not be required to qualify as a foreign corporation or
         to file a general consent to service of process in any such state.

                  (d) During the period of five years hereafter, the Company and
         CSK will furnish to CSFBC and, upon request, to each of the other
         Purchasers, as soon as practicable after the end of each fiscal year, a
         copy of its annual report to stockholders for such year; and the
         Company and CSK will furnish to CSFBC and, upon request, to each of the
         other Purchasers (i) as soon as available, a copy of each report and
         any definitive proxy statement of the Company and CSK filed with the
         Commission under the Exchange Act or mailed to stockholders, and (ii)
         from time to time, such other information concerning the Company and
         CSK as CSFBC may reasonably request.

                  (e) During the period of two years after the Closing Date, the
         Company will, upon request, furnish to CSFBC, each of the other
         Purchasers and any holder of Offered Securities a copy of the
         restrictions on transfer applicable to the Offered Securities.

                  (f) During the period of two years after the Closing Date,
         neither the Company nor CSK will, and will not permit any of its
         affiliates (as defined in Rule 144 under the Securities Act) to, resell
         any of the Offered Securities that have been reacquired by any of them.

                  (g) During the period of two years after the Closing Date,
         neither the Company nor CSK will be or become, an open-end investment
         company, unit investment trust or face-amount certificate company that
         is or is required to be registered under Section 8 of the Investment
         Company Act.

         will pay all expenses incidental to the performance of its obligations
         under this Agreement, the Indenture and the Registration Rights
         Agreement, including (i) the fees and expenses of the Trustee and its
         professional advisers; (ii) all expenses in connection with the

         thereto, and any other document relating to the issuance, offer, sale
         and delivery of the Offered Securities, the Guarantees and as
         applicable, the Exchange Securities; (iii) the cost of qualifying the
         Offered Securities and the Guarantees for trading in The PortalSM
         Market ("PORTAL") and any expenses incidental thereto; (iv) the cost of
         any advertising approved by the Company in connection with the issue of
         the Offered Securities; (v) for any expenses (including fees and
         disbursements of counsel) incurred in connection with qualification of
         the Offered Securities, the Guarantees or the Exchange Securities for
         sale under the laws of such jurisdictions in the United States and
         Canada as CSFBC designates and the printing of memoranda relating
         thereto; (vi) for any fees charged by investment rating agencies for
         the rating of the Offered Securities or the Exchange Securities, and
         (vi) for expenses incurred in distributing preliminary offering
         circulars and the Offering Document (including any amendments and
         supplements thereto) to the Purchasers. The Company will also pay or
         reimburse the Purchasers (to the extent incurred by them) for all
         travel expenses of the Purchasers and the Company's officers and
         employees and any other expenses of the Purchasers and the Company in
         connection with attending or hosting meetings with prospective
         purchasers of the Offered Securities from the Purchasers.

                  (i) In connection with the offering, until CSFBC shall have
         notified the Company and the other Purchasers of the completion of the
         resale of the Offered Securities, neither the Company nor any of its
         affiliates has or will, either alone or with one or more other persons,
         bid for or purchase for any account in which it or any of its
         affiliates has a beneficial interest any Offered Securities or attempt
         to induce any person to purchase any Offered Securities; and neither it
         nor any of its affiliates will make bids or purchases for the purpose
         of creating actual, or apparent, active trading in, or of raising the
         price of, the Offered Securities.

                  (j) Except for the sale by the Company of the Convertible
         Debentures (as defined below), from the date hereof through the Closing
         Date, each of the Company and the Guarantors will not offer, sell,
         contract to sell, pledge or otherwise dispose of, directly or
         indirectly, any United States dollar-denominated debt securities issued
         or guaranteed by the Company or any Guarantor and having a maturity of
         more than one year from the date of issue of the Offered Securities.
         Each of the Company and the Guarantors will not at any time offer,
         sell, contract to sell, pledge or otherwise dispose of, directly or
         indirectly, any securities under circumstances where such offer, sale,
         pledge, contract or disposition would cause the exemption afforded by
         Section 4(2) of the Securities Act or the safe harbor of Regulation S
         thereunder to cease to be applicable to the offer and sale of the
         Offered Securities.

                  (k) The Company and the Guarantors will use their respective
         best efforts to effect the inclusion of the Offered Securities and the
         Subsidiary Guarantees in PORTAL and to maintain the listing of the
         Offered Securities and the Subsidiary Guarantees on PORTAL for so long
         as the Offered Securities are outstanding.

                  (l) The Company and the Guarantors will obtain the approval of
         DTC for "book-entry" transfer of the Offered Securities and the
         Subsidiary Guarantees and will comply with all of their respective
         agreements set forth in the representation letters of the Company and
         the Guarantors to DTC relating to the approval of the Offered
         Securities and the Subsidiary Guarantees by DTC for "book-entry"
         transfer.

                  (m) Neither the Company nor any Guarantor will voluntarily
         claim, and each will actively resist any attempts to claim, the benefit
         of any usury laws against the holders of any Offered Securities and the
         related Subsidiary Guarantees.

                  (n) The Company and the Guarantors will comply with all of
         their respective agreements set forth in the Registration Rights
         Agreement.

                  (o) The Company and the Guarantors will use their respective
         best efforts to do and perform all things required or necessary to be
         done and performed under this Agreement by them prior to the Closing
         Date and to satisfy all conditions precedent to the delivery of the
         Offered Securities and the Subsidiary Guarantees.

                  (p) CSK will use its best efforts to cause the holders of its
         7% convertible subordinated debentures due December 2006 (the
         "CONVERTIBLE DEBENTURES") to fully convert such Convertible Debentures
         into shares of CSK common stock as promptly as practicable following
         the Closing Date.

         6. Conditions of the Obligations of the Purchasers. The obligations of
the several Purchasers to purchase and pay for the Offered Securities will be
subject to the accuracy of the representations and warranties on the part of the
Company and the Guarantors herein, to the accuracy of the statements of officers
of the Company and the Guarantors made pursuant to the provisions hereof, to the
performance by the Company and the Guarantors of their obligations hereunder and
to the following additional conditions precedent:

                  (a) The Purchasers shall have received a letter, dated the
         date of this Agreement, from PricewaterhouseCoopers LLP in agreed form
         confirming that they are independent public accountants within the
         meaning of the Securities Act and the applicable published rules and
         regulations thereunder ("RULES AND REGULATIONS") and to the effect
         that:

                           (i) in their opinion the financial statements
                  examined by them and included in the Offering Document and in
                  the Exchange Act Reports comply as to form in all material
                  respects with the applicable accounting requirements of the
                  Securities Act and the related published Rules and
                  Regulations;

                           (ii) they have performed the procedures specified by
                  the American Institute of Certified Public Accountants for a
                  review of interim financial information as described in
                  Statement of Auditing Standards No. 71, Interim Financial
                  Information, on the unaudited financial statements included in
                  the Offering Document and in the Exchange Act Reports;

                           (iii) on the basis of the review referred to in
                  clause (ii) above a reading of the latest available interim
                  financial statements of the Company, inquiries of officials of
                  the Company who have responsibility for financial and
                  accounting matters and other specified procedures, nothing
                  came to their attention that caused them to believe that:

                                    (A) the unaudited financial statements
                           included in the Offering Document or in the Exchange
                           Act Reports do not comply as to form in all material
                           respects with the applicable accounting requirements
                           of the Securities Act and the related published Rules
                           and Regulations or any material modifications should
                           be made to such unaudited financial statements for
                           them to be in conformity with generally accepted
                           accounting principles;

                                    (B) at the date of the latest available
                           balance sheet read by such accountants, or at a
                           subsequent specified date not more than three
                           business days prior to the date of this Agreement,
                           there was any change in the capital stock or any
                           increase in short-term indebtedness or long-term debt
                           of the Company and its consolidated subsidiaries or,
                           at the date of the latest available balance sheet
                           read by such accountants, there was any decrease in
                           consolidated net current assets or net


                                       12
<PAGE>
                           assets, as compared with amounts shown on the latest
                           balance sheet included in the Offering Document; or

                                    (C) for the period from the closing date of
                           the latest income statement included in the Offering
                           Document to the closing date of the latest available
                           income statement read by such accountants there were
                           any decreases, as compared with the corresponding
                           period of the previous year, in consolidated net
                           sales, net operating income, consolidated net income
                           or in the ratio of earnings to fixed charges;

                  except in all cases set forth in clauses (B) and (C) above for
                  changes, increases or decreases which the Offering Document
                  discloses have occurred or may occur or which are described in
                  such letter; and

                           (iv) they have compared specified dollar amounts (or
                  percentages derived from such dollar amounts) and other
                  financial information contained in the Offering Document and
                  the Exchange Act Reports (in each case to the extent that such
                  dollar amounts, percentages and other financial information
                  are derived from the general accounting records of the Company
                  and its subsidiaries subject to the internal controls of the
                  Company's accounting system or are derived directly from such
                  records by analysis or computation) with the results obtained
                  from inquiries, a reading of such general accounting records
                  and other procedures specified in such letter and have found
                  such dollar amounts, percentages and other financial
                  information to be in agreement with such results, except as
                  otherwise specified in such letter.

                  (b) Subsequent to the execution and delivery of this
         Agreement, there shall not have occurred (i) a change in U.S. or
         international financial political or economic conditions or currency
         exchange rates or exchange controls as would, in the judgment of CSFBC,
         be likely to prejudice materially the success of the proposed issue,
         sale or distribution of the Offered Securities, whether in the primary
         market or in respect of dealings in the secondary market, or (ii) (A)
         any change, or any development or event involving a prospective change,
         in the condition (financial or other), business, properties or results
         of operations of the Company and its subsidiaries which, in the
         judgment of a majority in interest of the Purchasers including CSFBC,
         is material and adverse and makes it impractical or inadvisable to
         proceed with completion of the offering or the sale of and payment for
         the Offered Securities; (B) any downgrading in the rating of any debt
         securities of the Company by any "nationally recognized statistical
         rating organization" (as defined for purposes of Rule 436(g) under the
         Securities Act), or any public announcement that any such organization
         has under surveillance or review its rating of any debt securities of
         the Company (other than an announcement with positive implications of a
         possible upgrading, and no implication of a possible downgrading, of
         such rating) or any announcement that the Company has been placed on
         negative outlook; (C) any suspension or limitation of trading in
         securities generally on the New York Stock Exchange, or any setting of
         minimum prices for trading on such exchange, or any suspension of
         trading of any securities of the Company on any exchange or in the
         over-the-counter market; (D) any banking moratorium declared by U.S.
         Federal or New York authorities; or (E) any disruption of settlement of
         securities; or (F) any attack on, outbreak or escalation of hostilities
         or act of terrorism involving the United States, any declaration of war
         by Congress or any other substantial national or international calamity
         or emergency if, in the judgment of a majority in interest of the
         Purchasers including CSFBC, the effect of any such attack, outbreak,
         escalation, act, declaration, calamity or emergency makes it
         impractical or inadvisable to proceed with completion of the offering
         or sale of and payment for the Offered Securities.

                  (c) The Purchasers shall have received an opinion, dated the
         Closing Date, from the office of the General Counsel to the Company and
         the Guarantors, that:

                           (i) The Company has been duly incorporated and is a
                  validly existing corporation in good standing under the laws
                  of the State of Arizona, with corporate power


                                       13
<PAGE>
                  and authority to own its properties and conduct its business
                  as described in the Offering Document and to execute, deliver,
                  issue and sell the Offered Securities; and the Company is duly
                  qualified to do business as a foreign corporation in good
                  standing in all other jurisdictions in which its ownership or
                  lease of property or the conduct of its business requires such
                  qualification, except to the extent that the failure to be so
                  qualified or be in good standing would not have a Material
                  Adverse Effect.

                           (ii) All of the outstanding shares of capital stock
                  of the Company have been duly authorized and validly issued
                  and are fully paid and non-assessable.

                           (iii) Each of the Guarantors is a validly existing
                  corporation in good standing under the laws of the
                  jurisdiction of its incorporation, with corporate power and
                  authority to own its respective properties and conduct its
                  respective business as described in the Offering Document and
                  to execute and deliver the Guarantees; and each Guarantor is
                  duly qualified to do business as a foreign corporation in good
                  standing in all other jurisdictions in which its ownership or
                  lease of property or the conduct of its business requires such
                  qualification, except to the extent that the failure to be so
                  qualified or be in good standing would not have a Material
                  Adverse Effect. The capital stock of each Guarantor owned by
                  the Company, directly or through subsidiaries, is, to the
                  knowledge of such counsel, owned free from liens, encumbrances
                  and defects (other than the liens to secure the Company's
                  obligations under its new credit facility, all of which are
                  disclosed in the Offering Circular, and other liens that
                  individually or in the aggregate would not have a Material
                  Adverse Effect).

                           (iv) The Indenture has been duly authorized, executed
                  and delivered by the Company and each Guarantor; the Offered
                  Securities have been duly authorized, executed and delivered
                  by the Company and the Guarantee of each Guarantor has been
                  duly authorized, executed and delivered by such Guarantor.

                           (v) The Exchange Securities have been duly
                  authorized, executed and delivered by the Company and the
                  Guarantee to be endorsed on the Exchange Securities by each
                  Guarantor has been duly authorized, executed and delivered by
                  such Guarantor.

                           (vi) This Agreement and the Registration Rights
                  Agreement have each been duly authorized, executed and
                  delivered by the Company and each of the Guarantors.

                           (vii) There are no pending actions, suits or
                  proceedings against the Company, any of its Guarantors or any
                  of their respective properties that would reasonably be
                  expected, individually or in the aggregate, to have a Material
                  Adverse Effect, or materially and adversely affect the ability
                  of the Company to perform its obligations under the Indenture,
                  this Agreement or the Registration Rights Agreement; and, to
                  such counsel's knowledge, no such actions, suits or
                  proceedings are threatened.

                           (viii) The execution, delivery and performance by the
                  Company and each Guarantor of the Indenture, this Agreement
                  and the Registration Rights Agreement to which it is a party,
                  and the issuance and sale of the Offered Securities and the
                  Guarantees in compliance with the terms and provisions hereof
                  and thereof, will not require any consent, authorization,
                  filing with or approval of any governmental authority or
                  regulatory body of the State of Arizona under any law or
                  regulation of the State of Arizona applicable to the Company
                  or such Guarantor that, in our experience, is generally
                  applicable to transactions in the nature of those contemplated
                  by this Agreement, except for such filings or approvals that,
                  if not made or obtained, would not have a Material Adverse
                  Effect. We are expressing no opinion in this paragraph
                  regarding the federal or any state securities laws.

                           (ix) The execution, delivery and performance by the
                  Company and each Guarantor of the Indenture, this Agreement,
                  the Registration Rights Agreement and the

<PAGE>
                  issuance and sale of the Offered Securities and the Guarantees
                  in compliance with the terms and provisions hereof and
                  thereof, will not (A) result in a breach or violation of any
                  of the terms and provisions of, or constitute a default under,
                  (i) any law or regulation of the State of Arizona applicable
                  to the Company or such Guarantor that, in our experience, is
                  generally applicable to transactions in the nature of those
                  contemplated by this Agreement, (ii) based solely upon review
                  of the orders, judgments or decrees identified to us in an
                  Officers' Certificate as constituting all orders, judgments or
                  decrees binding on the Company or any Guarantor, which are
                  listed in Schedule B to the opinion, any order, judgment or
                  decree of any court or other agency of government binding on
                  the Company or any Guarantor, (iii) based solely upon review
                  of the documents identified to me in an Officers' Certificate
                  as constituting all material contracts of the Company or any
                  Guarantor, which are listed in Schedule C to the opinion and
                  include, at a minimum, those Exhibits filed with CSK's most
                  recent Form 10-K, any exhibits filed by CSK with any
                  subsequent SEC filings and the new $300.0 million senior
                  secured credit facility entered into by the Company and the
                  purchase agreement, registration rights agreement and voting
                  agreement entered into by CSK in connection with the issuance
                  by CSK of the Convertible Debentures and the Convertible
                  Debentures and warrants issued in connection therewith (each a
                  "MATERIAL CONTRACT"), any Material Contract or (iv) the
                  charter or bylaws of the Company or any Guarantor, or (B)
                  result in or require the creation or imposition of any lien or
                  encumbrance upon any assets of the Company or any Guarantor
                  under any Material Contract. We are expressing no opinion in
                  this paragraph regarding the federal or any state securities
                  laws.

                  (d) The Purchasers shall have received an opinion, dated the
Closing Date, of Gibson, Dunn & Crutcher LLP, counsel for the Company and the
Guarantors, that:

                           (i) The Offered Securities conform in all material
                  respects to the description thereof contained in the Offering
                  Circular.

                           (ii) The Indenture constitutes, and the Offered
                  Securities, when executed and authenticated in accordance with
                  the provisions of the Indenture and delivered, and paid for by
                  the Purchasers in accordance with the terms of this Agreement,
                  will constitute, legal, valid and binding obligations of the
                  Company enforceable against the Company in accordance with
                  their terms.

                           (iii) The Guarantees of each Guarantor conform in all
                  material respects to the description thereof contained in the
                  Offering Circular.

                           (iv) When the Offered Securities and the Guarantees
                  have been executed and authenticated in accordance with the
                  provisions of the Indenture and delivered, and paid for by the
                  Purchasers in accordance with the terms of this Agreement, the
                  Guarantees will constitute legal, valid and binding
                  obligations of such Guarantor, enforceable against it in
                  accordance with their terms.

                           (v) When the Exchange Securities have been issued,
                  executed and authenticated in accordance with the terms of the
                  Exchange Offer and the Indenture in exchange for the Offered
                  Securities, the Exchange Securities will be entitled to the
                  benefits of the Indenture and the Exchange Securities will
                  constitute legal, valid and binding obligations of the
                  Company, enforceable against the Company in accordance with
                  their terms.

                           (vi) When the Exchange Securities (and the Guarantees
                  to be endorsed thereon) have been issued, executed and
                  authenticated in accordance with the terms of the Exchange
                  Offer and the Indenture in exchange for the Offered
                  Securities, the Guarantee of each Guarantor endorsed thereon
                  will constitute legal, valid and binding obligations of such
                  Guarantor, enforceable against it in accordance with its
                  terms.

                           (vii) The Registration Rights Agreement is a legal,
                  valid and binding obligation of the Company and each of the
                  Guarantors, enforceable against the Company and each Guarantor
                  in accordance with its terms.

                           (viii) The Company is not, and after giving effect to
                  the offering and sale of the Offered Securities and the
                  application of the proceeds thereof as described in the
                  Offering Circular the Company will not be, required to
                  register as an "investment company" as defined in the
                  Investment Company Act.

                           (ix) The execution, delivery and performance by the
                  Company and each Guarantor of the Indenture, this Agreement
                  and the Registration Rights Agreement to which it is a party,
                  and the issuance and sale of the Offered Securities and the
                  Guarantees in compliance with the terms and provisions hereof
                  and thereof, will not require any consent, authorization,
                  filing with or approval of any governmental authority or
                  regulatory body of the State of New York or the United States
                  of America under any law or regulation of the State of New
                  York or the United States of America applicable to the Company
                  or such Guarantor that, in our experience, is generally
                  applicable to transactions in the nature of those contemplated
                  by this Agreement, except for such filings or approvals that,
                  if not made or obtained, would not have a Material Adverse
                  Effect. We are expressing no opinion in this paragraph
                  regarding the federal or any state securities laws.

                           (x) The execution, delivery and performance by the
                  Company and each Guarantor of the Indenture, this Agreement,
                  the Registration Rights Agreement to which it is a party, and
                  the issuance and sale of the Offered Securities and the
                  Guarantees in compliance with the terms and provisions hereof
                  and thereof, will not (A) result in a breach or violation of
                  any of the terms and provisions of, or constitute a default
                  under, (i) any law or regulation of the State of New York or
                  the United States of America applicable to the Company or such
                  Guarantor that, in our experience, is generally applicable to
                  transactions in the nature of those contemplated by this
                  Agreement, (ii) based solely upon review of the orders,
                  judgments or decrees identified to us in an Officers'
                  Certificate as constituting all orders, judgments or decrees
                  binding on the Company or any Guarantor, which are listed in
                  Schedule B to the opinion, any order, judgment or decree of
                  any court or other agency of government binding on the Company
                  or any Guarantor or (iii) based solely upon review of the
                  Material Contracts, any Material Contract or (B) result in or
                  require the creation or imposition of any lien or encumbrance
                  upon any assets of the Company or any Guarantor under any
                  Material Contract. We are expressing no opinion in this
                  paragraph regarding the federal or any state securities laws.

                           (xi) No Material Contract grants any person the right
                  (1) except as disclosed in the Offering Circular, to require
                  the Company or such Guarantor to file a registration statement
                  under the Securities Act with respect to any securities of the
                  Company or such Guarantor or (2) to require the Company or
                  such Guarantor to include such securities with the Securities
                  and Guarantees registered pursuant to any Registration
                  Statement.

                           (xii) Assuming the accuracy of the representations
                  and warranties of the Purchasers and compliance by them with
                  their agreements contained in the Purchase Agreement, no
                  registration of the Offered Securities under the Securities
                  Act, and no qualification of the Indenture under the Trust
                  Indenture Act of 1939, as amended, is required for (1) the
                  offer, sale and delivery of the Offered Securities by the
                  Company to the several Purchasers pursuant to this Agreement
                  on the date hereof or (2) the resales of the Offered
                  Securities by the several Purchasers in the manner
                  contemplated by this Agreement, it being understood that we
                  express no opinion as to any subsequent resale of the Offered
                  Securities.

                           (xiii) The statements in the Offering Circular under
                  the caption "Certain United States Federal Income Tax
                  Consequences," insofar as such statements constitute a summary


                                       16
<PAGE>
                  of the United States federal tax laws referred to therein, are
                  accurate and fairly summarize in all material respects the
                  United States federal tax laws referred to therein.

         Such counsel shall state that (A) they have participated in conferences
with officers and other representatives of the Company, representatives of the
independent auditors of the Company and representatives of the Purchasers at
which the contents of the Offering Circular and related matters were discussed,
(B) because the purpose of their professional engagement was not to establish or
confirm factual matters and because the scope of our examination of the affairs
of the Company and the Guarantors did not permit us to verify the accuracy,
completeness or fairness of the statements set forth in the Offering Circular,
such counsel are not passing upon and do not assume any responsibility for the
accuracy, completeness or fairness of the statements contained in the Offering
Circular except to the extent set forth in paragraphs (i), (iii) and (xiii)
above and (C) on the basis of the foregoing, and except for the financial
statements and schedules and other financial data included therein as to which
we express no such belief, no facts have come to our attention that lead us to
believe that the Offering Circular, as of the date thereof and as of the date
hereof contained or contains an untrue statement of a material fact or omitted
or omits to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading.

                  (e) The Purchasers shall have received from Skadden, Arps,
         Slate, Meagher & Flom LLP, counsel for the Purchasers, such opinion or
         opinions, dated the Closing Date, with respect to the incorporation of
         the Company, the validity of the Offered Securities, the Offering
         Circular, the exemption from registration for the offer and sale of the
         Offered Securities by the Company to the several Purchasers and the
         resales by the several Purchasers as contemplated hereby and other
         related matters as CSFBC may require, and the Company shall have
         furnished to such counsel such documents as they request for the
         purpose of enabling them to pass upon such matters.

                  (f) The Purchasers shall have received a certificate, dated
         the Closing Date, of the President or any Vice President and a
         principal financial or accounting officer of the Company and each
         Guarantor in which such officers, to the best of their knowledge after
         reasonable investigation, shall state that the representations and
         warranties of the Company and the Guarantors in this Agreement are true
         and correct in all material respects (except for those representations
         and warranties that are already qualified as to materiality, in which
         case such representations and warranties shall be true in all
         respects), that the Company and the Guarantors have complied with all
         agreements and satisfied all conditions on its part to be performed or
         satisfied hereunder at or prior to the Closing Date, and that,
         subsequent to the respective dates of the most recent financial
         statements in the Offering Document there has been no material adverse
         change, nor any development or event involving a prospective material
         adverse change, in the condition (financial or other), business,
         properties or results of operations of the Company and the Guarantors
         taken as a whole except as set forth in or contemplated by the Offering
         Document or as described in such certificate.

                  (g) The Purchasers shall have received a letter, dated the
         Closing Date, of PricewaterhouseCoopers LLP which meets the
         requirements of subsection (a) of this Section, except that the
         specified date referred to in such subsection will be a date not more
         than three days prior to the Closing Date for the purposes of this
         subsection.

                  (h) The Company shall have entered into a new $300.0 million
         senior secured credit facility on terms substantially similar to the
         terms described in the Offering Circular, the cash proceeds of which
         shall be used to repay indebtedness outstanding under the Third Amended
         and Restated Credit Agreement, dated as of September 30, 1999, as
         amended, among the Company, The Chase Manhattan Bank, DLJ Capital
         Funding, Inc., Lehman Commercial Paper Inc. and the lenders referred to
         therein (the "EXISTING CREDIT AGREEMENT"). The Company shall deliver
         true and correct, fully executed copies of such new credit facility and
         any related documents to the Purchasers on the Closing Date.

                  (i) CSK shall have issued at least $50.0 million of
         Convertible Debentures on terms substantially similar to the terms
         described in the Offering Circular, the net cash proceeds of which


                                       17
<PAGE>
         shall be contributed to the Company and used to repay indebtedness
         outstanding under the Existing Credit Agreement. The Company shall
         deliver true and correct, fully executed copies of the Convertible
         Debentures and any related documents to the Purchasers on the Closing
         Date.

                  (j) CSK and the holders of a majority of the outstanding
         common stock of CSK (including the shares of common stock issuable upon
         conversion of CSK's 7% Convertible Subordinated Notes, dated August 14,
         2001) shall have entered into an irrevocable voting agreement wherein
         such stockholders shall have agreed to approve the issuance of the
         common stock underlying the Convertible Debentures and any related
         documents. The Company shall deliver true and correct, fully executed
         copies of the voting agreement and any related documents to the
         Purchasers on the Closing Date.

                  (k) CSK shall have irrevocably exercised its right to convert
         all of the unpaid principal amount of 7% Convertible Subordinated
         Notes, dated August 14, 2001, into shares of CSK common stock.

         The Company will furnish the Purchasers with such conformed copies of
such opinions, certificates, letters and documents as the Purchasers reasonably
request. CSFBC may in its sole discretion waive on behalf of the Purchasers
compliance with any conditions to the obligations of the Purchasers hereunder.

         7.       Indemnification and Contribution.

                  (a) The Company will indemnify and hold harmless each
         Purchaser, its partners, directors and officers and each person, if
         any, who controls such Purchaser within the meaning of Section 15 of
         the Securities Act, against any losses, claims, damages or liabilities,
         joint or several, to which such Purchaser may become subject, under the
         Securities Act or the Exchange Act or otherwise, insofar as such
         losses, claims, damages or liabilities (or actions in respect thereof)
         arise out of or are based upon any breach of any of the representations
         and warranties of the Company contained herein or any untrue statement
         or alleged untrue statement of any material fact contained in the
         Offering Document, or any amendment or supplement thereto, or any
         related preliminary offering circular or the Exchange Act Reports, or
         arise out of or are based upon the omission or alleged omission to
         state therein a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading, including any losses, claims, damages or liabilities
         arising out of or based upon the Company's failure to perform its
         obligations under Section 5(a) of this Agreement, and will reimburse
         each Purchaser for any legal or other expenses reasonably incurred by
         such Purchaser in connection with investigating or defending any such
         loss, claim, damage, liability or action as such expenses are incurred;
         provided, however, that the Company will not be liable in any such case
         to the extent that any such loss, claim, damage or liability arises out
         of or is based upon an untrue statement or alleged untrue statement in
         or omission or alleged omission from any of such documents in reliance
         upon and in conformity with written information furnished to the
         Company by any Purchaser through CSFBC specifically for use therein, it
         being understood and agreed that the only such information consists of
         the information described as such in subsection (b) below; provided
         further, that the foregoing indemnity agreement with respect to any
         Preliminary Offering Circular shall not inure to the benefit of any
         Purchaser who failed to deliver an Offering Circular, as then amended
         or supplemented (so long as the Offering Circular and any amendment or
         supplement thereto was provided by the Company to the several
         Purchasers in the requisite quantity and on a timely basis to permit
         proper delivery on or prior to the Closing Date), to the person
         asserting any losses, claims, damages, liabilities or judgments caused
         by any untrue statement or alleged untrue statement of a material fact
         contained in any Preliminary Offering Circular, or caused by any
         omission or alleged omission to state therein a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading, if such material misstatement or omission or alleged
         material misstatement or omission was cured in the Offering Circular,
         as so amended or supplemented.


                                       18
<PAGE>
                  (b) Each Purchaser will severally and not jointly indemnify
         and hold harmless the Company, its directors and officers and each
         person, if any, who controls the Company within the meaning of Section
         15 of the Securities Act, against any losses, claims, damages or
         liabilities to which the Company may become subject, under the
         Securities Act or the Exchange Act or otherwise, insofar as such
         losses, claims, damages or liabilities (or actions in respect thereof)
         arise out of or are based upon any untrue statement or alleged untrue
         statement of any material fact contained in the Offering Document, or
         any amendment or supplement thereto, or any related preliminary
         offering circular, or arise out of or are based upon the omission or
         the alleged omission to state therein a material fact necessary in
         order to make the statements therein, in the light of the circumstances
         under which they were made, not misleading, in each case to the extent,
         but only to the extent, that such untrue statement or alleged untrue
         statement or omission or alleged omission was made in reliance upon and
         in conformity with written information furnished to the Company by such
         Purchaser through CSFBC specifically for use therein, and will
         reimburse any legal or other expenses reasonably incurred by the
         Company in connection with investigating or defending any such loss,
         claim, damage, liability or action as such expenses are incurred, it
         being understood and agreed that the only such information furnished by
         any Purchaser consists of the following information in the Offering
         Document furnished on behalf of each Purchaser: under the caption "Plan
         of Distribution," the third sentence of paragraph nine and paragraph
         eleven; provided, however, that the Purchasers shall not be liable for
         any losses, claims, damages or liabilities arising out of or based upon
         the Company's failure to perform its obligations under Section 5(a) of
         this Agreement.

                  (c) Promptly after receipt by an indemnified party under this
         Section of notice of the commencement of any action, such indemnified
         party will, if a claim in respect thereof is to be made against the
         indemnifying party under subsection (a) or (b) above, notify the
         indemnifying party of the commencement thereof; but the omission so to
         notify the indemnifying party will not relieve it from any liability
         which it may have to any indemnified party otherwise than under
         subsection (a) or (b) above. In case any such action is brought against
         any indemnified party and it notifies the indemnifying party of the
         commencement thereof, the indemnifying party will be entitled to
         participate therein and, to the extent that it may wish, jointly with
         any other indemnifying party similarly notified, to assume the defense
         thereof, with counsel satisfactory to such indemnified party (who shall
         not, except with the consent of the indemnified party, be counsel to
         the indemnifying party), and after notice from the indemnifying party
         to such indemnified party of its election so to assume the defense
         thereof, the indemnifying party will not be liable to such indemnified
         party under this Section 7 for any legal or other expenses subsequently
         incurred by such indemnified party in connection with the defense
         thereof other than reasonable costs of investigation. No indemnifying
         party shall, without the prior written consent of the indemnified
         party, effect any settlement of any pending or threatened action in
         respect of which any indemnified party is or could have been a party
         and indemnity could have been sought hereunder by such indemnified
         party unless such settlement includes an unconditional release of such
         indemnified party from all liability on any claims that are the subject
         matter of such action and does not include a statement as to or an
         admission of fault, culpability or failure to act by or on behalf of
         any indemnified party.

                  (d) If the indemnification provided for in this Section 7 is
         unavailable or insufficient to hold harmless an indemnified party under
         subsection (a) or (b) above, then each indemnifying party shall
         contribute to the amount paid or payable by such indemnified party as a
         result of the losses, claims, damages or liabilities referred to in
         subsection (a) or (b) above (i) in such proportion as is appropriate to
         reflect the relative benefits received by the Company on the one hand
         and the Purchasers on the other from the offering of the Offered
         Securities or (ii) if the allocation provided by clause (i) above is
         not permitted by applicable law, in such proportion as is appropriate
         to reflect not only the relative benefits referred to in clause (i)
         above but also the relative fault of the Company on the one hand and
         the Purchasers on the other in connection with the statements or
         omissions which resulted in such losses, claims, damages or liabilities
         as well as any other relevant equitable considerations. The relative
         benefits received by the Company on the one hand and the Purchasers on
         the other shall be deemed to be in the same proportion as the total net
         proceeds from the offering (before deducting expenses) received by the
         Company bear to the total discounts and commissions


                                       19

         received by the Purchasers from the Company under this Agreement. The
         relative fault shall be determined by reference to, among other things,
         whether the untrue or alleged untrue statement of a material fact or
         the omission or alleged omission to state a material fact relates to
         information supplied by the Company or the Purchasers and the parties'
         relative intent, knowledge, access to information and opportunity to
         correct or prevent such untrue statement or omission. The amount paid
         by an indemnified party as a result of the losses, claims, damages or
         liabilities referred to in the first sentence of this subsection (d)
         shall be deemed to include any legal or other expenses reasonably
         incurred by such indemnified party in connection with investigating or
         defending any action or claim which is the subject of this subsection
         (d). Notwithstanding the provisions of this subsection (d), no
         Purchaser shall be required to contribute any amount in excess of the
         amount by which the total discounts, fees and commissions received by
         such Purchaser exceeds the amount of any damages which such Purchaser
         has otherwise been required to pay by reason of such untrue or alleged
         untrue statement or omission or alleged omission. The Purchasers'
         obligations in this subsection (d) to contribute are several in
         proportion to their respective purchase obligations and not joint.

                  (e) The obligations of the Company under this Section 7 shall
         be in addition to any liability which the Company may otherwise have
         and shall extend, upon the same terms and conditions, to each person,
         if any, who controls any Purchaser within the meaning of the Securities
         Act or the Exchange Act; and the obligations of the Purchasers under
         this Section shall be in addition to any liability which the respective
         Purchasers may otherwise have and shall extend, upon the same terms and
         conditions, to each person, if any, who controls the Company within the
         meaning of the Securities Act or the Exchange Act.

         8. Default of Purchasers. If any Purchaser or Purchasers default in
their obligations to purchase Offered Securities hereunder and the aggregate
principal amount of Offered Securities that such defaulting Purchaser or
Purchasers agreed but failed to purchase does not exceed 10% of the total
principal amount of Offered Securities, CSFBC may make arrangements satisfactory
to the Company for the purchase of such Offered Securities by other persons,
including any of the Purchasers, but if no such arrangements are made by the
Closing Date, the non-defaulting Purchasers shall be obligated severally, in
proportion to their respective commitments hereunder, to purchase the Offered
Securities that such defaulting Purchasers agreed but failed to purchase. If any
Purchaser or Purchasers so default and the aggregate principal amount of Offered
Securities with respect to which such default or defaults occur exceeds 10% of
the total principal amount of Offered Securities and arrangements satisfactory
to CSFBC and the Company for the purchase of such Offered Securities by other
persons are not made within 36 hours after such default, this Agreement will
terminate without liability on the part of any non-defaulting Purchaser or the
Company, except as provided in Section 9. As used in this Agreement, the term
"Purchaser" includes any person substituted for a Purchaser under this Section.
Nothing herein will relieve a defaulting Purchaser from liability for its
default.

         9. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Purchasers set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation, or statement as to the results thereof, made by or on behalf
of any Purchaser, the Company or any of their respective representatives,
officers or directors or any controlling person, and will survive delivery of
and payment for the Offered Securities. If this Agreement is terminated pursuant
to Section 8 or if for any reason the purchase of the Offered Securities by the
Purchasers is not consummated, the Company shall remain responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations of the Company and the Purchasers pursuant to Section 7 shall remain
in effect. If the purchase of the Offered Securities by the Purchasers is not
consummated for any reason other than solely because of the termination of this
Agreement pursuant to Section 8 or the occurrence of any event specified in
clause (C), (D) or (E) of Section 6(b)(ii), the Company will reimburse the
Purchasers for all out-of-pocket expenses (including fees and disbursements of
counsel) reasonably incurred by them in connection with the offering of the
Offered Securities.

         10. Notices. All communications hereunder will be in writing and, if
sent to the Purchasers will be mailed, delivered or telegraphed and confirmed to
the Purchasers, c/o Credit Suisse First Boston
