Statement as a selling securityholder in the Shelf Registration Statement at the

Holder that is not an Election Holder as a selling securityholder in the Shelf
Registration Statement.

                  (ii) (A) After the Shelf Registration Statement has become
      effective, the Company shall, upon the request of any Holder of Transfer

      and Questionnaire is delivered to the Company, and in any event (subject
      to clause (B) below) within 15 Business Days (excluding any days within a
      Suspension Period) after such date, prepare and file with the SEC (x) a
      supplement to the Prospectus or, if a post-effective amendment to the
      Shelf Registration Statement is required by applicable law in order to
      cause a Holder to be named as a selling securityholder in the Shelf
      Registration Statement, a post-effective amendment to the Shelf
      Registration Statement (a "SELLER POST-EFFECTIVE AMENDMENT") and (y) any
      other document required by applicable law, so that the Holder delivering
      such Election and Questionnaire is named as a selling securityholder in
      the Shelf Registration


                                       5
<PAGE>
      Statement and is permitted to deliver the Prospectus to purchasers of such

      If the Company, CSK Corp. and the Subsidiary Guarantor file a Seller
      Post-Effective Amendment, they shall use their reasonable best efforts to
      cause such post-effective amendment to become effective under the
      Securities Act as promptly as is practicable and in any event within 90
      days (excluding any days within a Suspension Period) of such filing.

                        (B) Notwithstanding Section 3(p) below or the 15
            Business-Day requirement of clause (A) above, none of the Company,
            CSK Corp. or any of the Subsidiary Guarantor shall be required to
            file more than one Seller Post-Effective Amendment in any fiscal
            quarter, provided that this clause (B) shall not relieve the
            Company, CSK Corp. and the Subsidiary Guarantor of any obligations
            under clause (A) unless a Seller Post-Effective Amendment is
            required, as determined by the Company's and CSK Corp.'s outside
            counsel, by applicable law in order to cause a Holder to be named as
            a selling securityholder in the Shelf Registration Statement.

            (c) The Company, CSK Corp. and the Subsidiary Guarantor shall use
their reasonable best efforts to keep the Shelf Registration Statement
continuously effective, supplemented and amended under the Securities Act in
order to permit the Prospectus forming a part thereof to be usable, subject to
Sections 2(b)(ii) and 2(d), by all Election Holders until all Transfer
Restricted Securities (A) have been transferred pursuant to a Shelf Registration
Statement or another registration statement covering such Security or share of
Common Stock which has been filed with the SEC pursuant to the Securities Act,
in either case after such registration statement has become effective and while

transferability thereof, under the Securities Act or otherwise, is removed, (C)
may be sold or transferred pursuant to Rule 144(k) were it not held by an
Affiliate of the Company or (D) have ceased to be outstanding (in any such case,
such period being called the "SHELF REGISTRATION Period"). The Company, CSK
Corp. and the Subsidiary Guarantor will, (x) subject to Sections 2(b)(ii) and
2(d), use their reasonable best efforts to prepare and file with the SEC such
amendments and post-effective amendments to the Shelf Registration Statement as
may be necessary to keep the Shelf Registration Statement continuously effective
for the Shelf Registration Period, (y) subject to Sections 2(b)(ii) and 2(d),
cause the related Prospectus to be supplemented by any required supplement, and
as so supplemented to be filed pursuant to Rule 424 (or any similar provisions
then in force) under the Securities Act and (z) comply in all material respects
with the provisions of the Securities Act with respect to the Shelf Registration
Statement during the Shelf Registration Period.

            (d) The Company, CSK Corp. and the Subsidiary Guarantor may suspend
the availability of any Shelf Registration Statement and the use of any
Prospectus (the period during which the availability of any Shelf Registration
Statement and any Prospectus may be suspended herein referred to as the
"SUSPENSION PERIOD"), without incurring any obligation to pay Additional
Interest pursuant to Section 2(e), for a period not to exceed 90 calendar days
in the aggregate during any 360 calendar-day period for valid business reasons,
to be determined by the Company and CSK Corp. in their sole judgment (which
shall not include the avoidance of the


                                       6
<PAGE>
Company's or CSK Corp.'s obligations hereunder), including, without limitation,
the acquisition or divestiture of assets, pending corporate developments, events
listed in Section 3(c), public filings with the SEC and similar events; provided
that the Company, CSK Corp. and the Subsidiary Guarantor promptly thereafter
comply with the requirements of Section 3(j) hereof, if applicable, and provided
further that, if a Seller Post-Effective Amendment is required by applicable law
in order to cause a Holder to be named as a selling securityholder in the Shelf
Registration Statement, the period of time between the filing and effectiveness
of any Seller Post-Effective Amendment shall not be deemed to be a Suspension
Period hereunder.

            (e) The Company, CSK Corp. and the Initial Purchasers agree that the
Holders of Transferred Restricted Securities will suffer damages, and it would
not be feasible to ascertain the extent of such damages with precision, if the
Company or CSK Corp. fails to fulfill its obligations under Section 2 hereof.
Accordingly, if (i) the Shelf Registration Statement is not filed with the SEC
within 90 calendar days after the Closing Date, (ii) the Shelf Registration
Statement has not been declared effective by the SEC within 180 calendar days
after the Closing Date, (iii) the Shelf Registration Statement is filed and
declared effective but shall thereafter cease to be effective (without being
succeeded immediately by a replacement Shelf Registration Statement filed and
declared effective) or usable (including as a result of a Suspension Period and
excluding as a result of a Seller Post-Effective Amendment that is required by
applicable law in order to cause an Election Holder to be named as a selling
sedurityholder therein) for the offer and sale of Transfer Restricted Securities
for a period of time (including any Suspension Period and excluding, if a Seller
Post-Effective Amendment is required by applicable law in order to cause an
Election Holder to be named as a selling securityholder in the Shelf
Registration Statement, the period of time between the filing and effectiveness
of any Seller Post-Effective Amendment) which exceeds 90 calendar days in the
aggregate in any 360 calendar-day period or (iv) the Company and CSK Corp. fail
to perform their obligations set forth in Section 2(b)(ii) within the time
periods required therein (each such event referred to in clauses (i) through
(iv), a "REGISTRATION DEFAULT"), the Company shall pay to each Holder of
Transfer Restricted Securities (who is also a Record Holder) during any period
in which a Registration Default has occurred or is continuing an amount (the
"ADDITIONAL INTEREST") equal to (i) one-quarter of one percent (25 basis points)
per year of the outstanding principal amount of Securities constituting Transfer
Restricted Securities for the period up to and including the 90th calendar day
during which a Registration Default has occurred and is continuing and (ii)
one-half of one percent (50 basis points) per year of the outstanding principal
amount of Securities constituting Transfer Restricted Securities for the period
including and subsequent to the 91st calendar day during which a Registration
Default has occurred and is continuing, it being understood that all
calculations pursuant to this sentence shall be carried out to five decimal
places. Following the cure of all Registration Defaults, Additional Interest
will cease to accrue with respect to such Registration Defaults. All accrued
Additional Interest shall be paid by the Company on each Additional Interest
Payment Date in cash and Additional Interest will be calculated on the basis of
a 360 calendar-day year consisting of twelve 30 calendar-day months. The parties
hereto agree that the Additional Interest provided for in this Section 2(e)
constitutes a reasonable estimate of the damages that may be incurred by
Election Holders by reason of a Registration Default and that such Additional
Interest is the only monetary damage available to Election Holders in the event
of a Registration Default. Notwithstanding any provision herein to the contrary,
Additional Interest shall not be payable to any Holder of shares of Common Stock
issued upon exchange of


                                       7
<PAGE>
the Securities, or in respect of cash paid in lieu of Common Stock upon exchange
of the Securities.

            (f) All of the Company's, CSK's and the Subsidiary Guarantor's
obligations (including, without limitation, the Company's obligation to pay
Additional Interest) set forth in the preceding paragraph which are outstanding
or exist with respect to any Transfer Restricted Security at the time such
security ceases to be a Transfer Restricted Security shall survive until such
time as all such obligations with respect to such security shall have been
satisfied in full. Notwithstanding the foregoing, no Additional Interest shall
accrue as to any Transfer Restricted Security from and after the date such
security is no longer a Transfer Restricted Security.

            (g) Immediately upon the occurrence or the cure of a Registration
Default, the Company shall give the Trustee, so long as the Securities remain
outstanding, notice of such commencement or termination of the obligation to pay
Additional Interest with regard to the Securities, the amount or applicable
percentage thereof and the nature of the Registration Default giving rise to
such commencement or the event giving rise to such termination, as the case may
be (such notice to be contained in an Officer's Certificate (as such term is
defined in the Indenture)), and, prior to receipt of such Officer's Certificate,
the Trustee shall be entitled to assume that no such commencement or termination
has occurred, as the case may be.

            3. Registration Procedures. In connection with any Shelf
Registration Statement, the following provisions shall apply:

            (a) The Company, CSK Corp. and the Subsidiary Guarantor shall (i)

review, a copy of each Shelf Registration Statement, and each amendment thereof,
and a copy of each Prospectus, and each amendment or supplement thereto
(excluding amendments caused by the filing of a report under the Exchange Act),
and shall reflect in each such document, when so filed with the SEC, such
comments as the Initial Purchasers may reasonably propose, except to the extent
the Company, CSK Corp. and the Subsidiary Guarantor reasonably determine, on the
advice of counsel, it to be inadvisable or inappropriate to reflect such
comments therein, and (ii) include information regarding the Election Holders
and the methods of distribution they have elected for their Transfer Restricted
Securities provided to the Company in Election and Questionnaires as necessary
to permit such distribution by the methods specified therein. Each Election
Holder who sells, transfers or disposes of Transfer Restricted Securities
pursuant to the Shelf Registration Statement shall, as a condition to the
obligations of the Company, CSK Corp. and the Subsidiary Guarantor hereunder, do
so only in accordance with the terms of this Agreement, the methods of
distribution elected by such Election Holder, the Securities Act and the
Exchange Act.

            (b) Subject to Sections 2(b)(ii) and 2(d), the Company, CSK Corp.
and the Subsidiary Guarantor shall ensure that (i) any Shelf Registration
Statement and any amendment thereto and any Prospectus forming a part thereof
and any amendment or supplement thereto comply in all material respects with the
Securities Act and the rules and regulations thereunder, (ii) any Shelf
Registration Statement and any amendment thereto does not, when it becomes
effective, contain an untrue statement of a material fact or omit to state a
material fact required to


                                       8
<PAGE>
be stated therein or necessary to make the statements therein not misleading and
(iii) any Prospectus forming a part of any Shelf Registration Statement, and any
amendment or supplement to such Prospectus, does not include an untrue statement
of a material fact or omit to state a material fact necessary in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading; provided that the Company, CSK Corp. and the Subsidiary
Guarantor make no representation with respect to any Holder Information.

            (c) The Company as promptly as reasonably practicable (but in any
event within two Business Days), shall notify the Initial Purchasers and each
Election Holder and, if requested by you or any such Election Holder, confirm
such notice in writing:

      amendment thereto or any Prospectus or any amendment or supplement thereto
      has been filed with the SEC and when the Shelf Registration Statement or
      any post-effective amendment thereto has become effective, which notice
      and confirmation may be made at the election of the Company and CSK Corp.
      by making a public announcement thereof by a press release made through
      Reuters Economic Services or Bloomberg Business News;

      Registration Statement under the Securities Act, by the SEC or any other
      federal or state governmental authority for amendments or supplements to
      the Shelf Registration Statement or the Prospectus or for additional
      information (other than any such request relating to a review of the
      Company's or CSK Corp.'s Exchange Act filings);

                  (iii) of the issuance by the SEC or any other federal or state
      governmental authority of any stop order suspending the effectiveness of
      the Shelf Registration Statement or of any order preventing or suspending
      the use of any Prospectus or the initiation or threat of any proceedings
      for that purpose;

                  (iv) of the receipt by the Company or CSK Corp. of any
      notification with respect to the suspension of the qualification or
      exemption from qualification of the Transfer Restricted Securities
      included in any Shelf Registration Statement for sale in any jurisdiction
      or the initiation or threat of any proceeding for that purpose;

                  (v) of the occurrence of any event or the existence of any
      condition or any information becoming known that requires the making of
      any changes in the Shelf Registration Statement or the Prospectus or any
      document incorporated by reference therein so that, as of such date, the
      statements therein are not misleading and the Shelf Registration Statement
      or the Prospectus or any document incorporated by reference therein, as
      the case may be, does not include an untrue statement of a material fact
      or omit to state a material fact required to be stated therein or
      necessary to make the statements therein (in the case of the Prospectus,
      in light of the circumstances under which they were made) not misleading;


                                       9
<PAGE>
                  (vi) of the Company's and CSK Corp.'s determination that a
      post-effective amendment to the Shelf Registration Statement is necessary;
      and

                  (vii) of the commencement (including as a result of any of the
      events or circumstances described in paragraphs (ii) through (vi) above)
      and termination of any Suspension Period; provided that the Company's or
      CSK Corp.'s actions pursuant to Section 3(c)(vi) shall not constitute a
      Suspension Period if taken pursuant to Section 2(b)(ii).

            (d) The Company, CSK Corp. and the Subsidiary Guarantor shall use
their reasonable best efforts to obtain (i) the withdrawal of any order
suspending the effectiveness of any Shelf Registration Statement and the use of
any related Prospectus and (ii) the lifting of any suspension of the
qualification (or exemption from qualification) of any of the Transfer
Restricted Securities for offer or sale in any jurisdiction in which they have
been qualified for sale, in each case at the earliest possible time, and shall
provide notice to each Election Holder and the Initial Purchasers of the
withdrawal of any such orders or suspensions.

            (e) The Company shall promptly furnish to the Initial Purchasers and
each Election Holder who so requests to the Company, without charge, at least
one copy of any Shelf Registration Statement and any post-effective amendment
thereto, excluding all documents incorporated or deemed to be incorporated
therein by reference and all exhibits thereto (unless requested by such Election
Holder).

            (f) The Company shall, during the Shelf Registration Period,
promptly deliver to the Initial Purchasers, each Election Holder and any
broker-dealers acting on their behalf, without charge, as many copies of the
Prospectus (including each preliminary Prospectus) included in any Shelf
Registration Statement, and any amendment or supplement thereto, as such person
may reasonably request, except as provided in Sections 2(d) and 3(r) hereof; and
the Company, CSK Corp. and the Subsidiary Guarantor hereby consent (except
during a Suspension Period and, with respect to an Election Holder named in the
Seller Post-Effective Amendment, during the period of time between the filing
and effectiveness of a Seller Post-Effective Amendment filed pursuant to Section
2(b)(ii)) to the use of the Prospectus and any amendment or supplement thereto
by each of the selling Election Holders in connection with the offering and sale
of the Transfer Restricted Securities covered by the Prospectus or any amendment
or supplement thereto in the manner set forth therein.

            (g) Prior to any offering of Transfer Restricted Securities pursuant
to any Shelf Registration Statement, the Company, CSK Corp. and the Subsidiary
Guarantor shall register or qualify or cooperate with the Election Holders and
their respective counsel in connection with the registration or qualification
(or exemption from such registration or qualification) of such Transfer
Restricted Securities for offer and sale, under the securities or blue sky laws
of such jurisdictions within the United States as any such Election Holders
reasonably request in writing and shall maintain such qualification in effect so
long as required during the Shelf Registration Period and do any and all other
acts or things reasonably necessary or advisable to enable the offer and sale in
such jurisdictions of the Transfer Restricted Securities covered by such Shelf
Registration Statement; provided, however, that the Company, CSK Corp. and the
Subsidiary Guarantor will not be required to (A) qualify generally to do
business as a


                                       10
<PAGE>
foreign corporation or as a dealer in securities in any jurisdiction where it is
not then so qualified or to (B) take any action which would subject them to
service of process or taxation in any such jurisdiction where they are not then
so subject.

            (h) The Company, CSK Corp. and the Subsidiary Guarantor shall
cooperate with the Election Holders to facilitate the timely preparation and
delivery of certificates representing Transfer Restricted Securities (to the
extent certificates for the Securities or the Common Stock issued upon exchange
of Securities are issuable under the Indenture) sold pursuant to any Shelf
Registration Statement free of any restrictive legends and, with respect of any
Securities, in such denominations permitted by the Indenture and registered in
such names as such Election Holders may request at least one Business Day prior
to settlement of sales of Transfer Restricted Securities pursuant to such Shelf
Registration Statement.

            (i) Subject to the exceptions contained in (A) and (B) of Section
3(g) above, the Company, CSK Corp. and the Subsidiary Guarantor shall use their
reasonable best efforts to cause the Transfer Restricted Securities covered by
the applicable Shelf Registration Statement to be registered with or approved by
such other federal, state and local governmental agencies or authorities, and
self-regulatory organizations in the United States as may be necessary to enable
the Election Holders to consummate the disposition of such Transfer Restricted
Securities as contemplated by the Shelf Registration Statement; without
limitation to the foregoing, the Company and CSK Corp. shall provide all such
information as may be required by the National Association of Securities
Dealers, Inc. (the "NASD") in connection with the offering under the Shelf
Registration Statement of the Transfer Restricted Securities (including, without
limitation, such as may be required by NASD Rule 2710 or 2720), and shall
cooperate with each Holder in connection with any filings required to be made
with the NASD by such Holder in that regard.

            (j) Upon the occurrence of any event described in Section 3(c)(v) or
3(c)(vi) hereof, the Company, CSK Corp. and the Subsidiary Guarantor shall
promptly prepare and file with the SEC a post-effective amendment to any Shelf
Registration Statement, or an amendment or supplement to the related Prospectus,
or any document incorporated therein by reference, or file a document which is
incorporated or deemed to be incorporated by reference in such Shelf
Registration Statement or Prospectus, as the case may be, so that, as thereafter
delivered to purchasers of the Transfer Restricted Securities included therein,
the Shelf Registration Statement and the Prospectus, in each case as then
amended or supplemented, will not include an untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements therein (in the case of the Prospectus, in light of
the circumstances under which they were made) not misleading and, in the case of
a post-effective amendment, use its reasonable best efforts to cause it to
become effective as promptly as practicable; provided that the Company's, CSK
Corp.'s and the Subsidiary Guarantor's obligations under this paragraph (j)
shall be suspended if the Company or CSK Corp. has suspended the use of the
Prospectus in accordance with Section 2(d) hereof and given notice of such
suspension to Election Holders, it being understood that the Company's, CSK
Corp.'s and the Subsidiary Guarantor's obligations under this Section 3(j) shall
be automatically reinstated at the end of such Suspension Period.

            (k) The Company shall provide, prior to the effective date of any
Shelf Registration Statement hereunder (i) a CUSIP number for the Securities
registered under such


                                       11
<PAGE>
Shelf Registration Statement that cease to be Transfer Restricted Securities and
(ii) global certificates for such Securities to the Trustee, in a form eligible
for deposit with DTC.

            (l) The Company and CSK Corp. shall make generally available to its
security holders an earnings statement satisfying the provisions of Section
11(a) of the Securities Act and Rule 158 promulgated by the SEC thereunder (or
any similar rule promulgated under the Securities Act) for a 12-month period
commencing on the first day of the first fiscal quarter of the Company and CSK
Corp. commencing after the effective date of any Shelf Registration Statement or
each post-effective amendment to any Shelf Registration Statement, which such
statements shall be made available no later than 45 days after the end of the
12-month period or 90 days after the end of the 12-month period, if the 12-month
period coincides with the fiscal year of the Company and CSK Corp.

            (m) The Company, CSK Corp. and the Subsidiary Guarantor shall cause
the Indenture to be qualified under the TIA (as defined in the Indenture) not
later than the effective date of the first Shelf Registration Statement.

            (n) CSK Corp. shall use its reasonable best efforts to cause all
shares of Common Stock issuable upon exchange of the Securities to be approved
for listing upon official notice of issuance on each securities exchange or
quotation system on which the Common Stock is then listed no later than the date
the applicable Shelf Registration Statement is declared effective and, in
connection therewith, to make such filings as may be required under the Exchange
Act and to have such filings declared effective as and when required thereunder.

            (o) The Company, CSK Corp. and the Subsidiary Guarantor may require
each Election Holder of Transfer Restricted Securities to be sold pursuant to
any Shelf Registration Statement to furnish to the Company such information
regarding the Election Holder and the distribution of such Transfer Restricted
Securities sought by the Election and Questionnaire and such additional
information as may, from time to time, be required by the Securities Act and/or
the SEC or any other federal or state governmental authority, and the
obligations of the Company, CSK Corp. and the Subsidiary Guarantor to any
Election Holder under this Agreement shall be expressly conditioned on the
compliance of such Election Holder with such request.

            (p) The Company, CSK Corp. and the Subsidiary Guarantor shall, if
reasonably requested, promptly incorporate in a Prospectus supplement or
post-effective amendment to a Shelf Registration Statement (i) such information
as the Majority Holders provide and (ii) such information as an Election Holder
may provide from time to time to the Company in writing for inclusion in a
Prospectus or any Shelf Registration Statement concerning such Election Holder
and the distribution of such Holder's Transfer Restricted Securities and, in
either case, shall make all required filings of such Prospectus supplement or
post-effective amendment promptly after being notified in writing of the matters
to be incorporated in such Prospectus supplement or post-effective amendment;
provided that the Company, CSK Corp. and the Subsidiary Guarantor shall not be
required to file more than one Seller Post-Effective Amendment in any fiscal
quarter or to take any action under this Section 3(p) that is not, in the
reasonable opinion of counsel for the Company, CSK Corp. and the Subsidiary
Guarantor, in compliance with applicable law.


                                       12
<PAGE>
            (q) If reasonably requested in writing in connection with any
disposition of Transfer Restricted Securities pursuant to a Shelf Registration
Statement, make reasonably available for inspection during normal business hours
by a representative for the Election Holders of such Transfer Restricted
Securities and any broker-dealers, attorneys and accountants retained by such
Election Holders, all relevant financial and other records, pertinent corporate
documents and properties of CSK Corp. and its subsidiaries (including the
Company), and cause the appropriate executive officers, directors and designated
employees of CSK Corp. and its subsidiaries (including the Company) to make
reasonably available for inspection during normal business hours all relevant
information reasonably requested by such representative for the Election Holders
or any such broker-dealers, attorneys or accountants in connection with such
disposition, in each case as is customary for similar "due diligence"
examinations; provided that CSK Corp. and its subsidiaries shall only be
required to permit such inspection (i) in an underwritten offering or (ii) in a
non-underwritten offering if the Election Holder of such Transfer Restricted
Securities is advised by counsel that it may have "underwriters' liability"
under the Securities Act in connection with such disposition and such inspection
is used solely for the purposes of establishing a defense to liability under the
securities laws; provided, however, that any information that is designated by
the Company and CSK Corp., in good faith, as confidential at the time of
delivery of such information shall be kept confidential by such persons, unless
disclosure thereof is made in connection with a court, administrative or
regulatory proceeding or required by law, or such information has become
available to the public generally through the Company, CSK Corp. or through a
third party without an accompanying obligation of confidentiality, and the
Company may, at its option, require all such Election Holders and
representatives to sign a standard confidentiality agreement prior to permitting
access to such information.

            (r) Each Election Holder agrees that, upon receipt of notice of the
happening of an event described in Sections 3(c)(ii) through and including
3(c)(vii), such Election Holder shall forthwith discontinue (and shall cause its
agents and representatives to discontinue) disposition of Transfer Restricted
Securities and will not resume disposition of Transfer Restricted Securities
until such Election Holder has received copies of an amended or supplemented
Prospectus contemplated by Section 3(j) hereof, or until such Holder is advised
in writing by the Company that the use of the Prospectus may be resumed or that
the relevant Suspension Period has been terminated, as the case may be, provided
that the foregoing shall not prevent the sale, transfer or other disposition of
Transfer Restricted Securities by an Election Holder in a transaction which is
exempt from, or not subject to, the registration requirements of the Securities
Act, so long as such Election Holder does not and is not required to deliver the
applicable Prospectus or Shelf Registration Statement in connection with such
sale, transfer or other disposition, as the case may be; and provided, further,
that the provisions of this Section 3(r) shall not prevent the occurrence of a
Registration Default or otherwise limit the obligation of the Company to pay
Additional Interest.

            (s) Each Election Holder shall promptly notify the Company of any
inaccuracies or changes in the information provided in such Election Holder's
Election and Questionnaire that may occur subsequent to the date thereof at any
time while the Shelf Registration Statement remains effective. Upon any sale of
Registrable Securities pursuant to the Shelf Registration Statement or
otherwise, each Election Holder hereby agrees to deliver to


                                       13
<PAGE>
the Company, CSK Corp. and the Trustee a duly completed and executed Notice of
Transfer in substantially the form set forth in Exhibit A to the Offering
Memorandum.

            4. Registration Expenses. The Company shall bear all fees and
expenses incurred in connection with the performance of the obligations of the
Company, CSK Corp. and the Subsidiary Guarantor under Sections 2 and 3 hereof.
Such fees and expenses shall include, without limitation: (i) all registration
and filing fees and expenses (including filings made with the NASD); (ii) all
fees and expenses of compliance with federal securities and state Blue Sky or
securities laws; (iii) all expenses of printing (including printing of
Prospectuses and certificates for the Common Stock to be issued upon exchange of
the Securities) and the Company's, CSK Corp.'s and the Subsidiary Guarantor's
expenses for messenger and delivery services and telephone; (iv) all fees and
disbursements of counsel to the Company, CSK Corp. and the Subsidiary Guarantor
and, in the case of the Shelf Registration Statement, and any amendment and
supplement thereto, the fees and disbursements (not exceeding $15,000 in the
aggregate) of the counsel for the Initial Purchasers and the Holders (which
counsel shall initially be Simpson Thacher & Bartlett LLP until such time as the
Majority Holders shall have elected a different counsel); (v) all application
and filing fees in connection with listing (or authorizing for quotation) the
Common Stock on a national securities exchange or automated quotation system
pursuant to the requirements hereof; and (vi) all fees and disbursements of
independent certified public accountants of the Company, CSK Corp. and the
Subsidiary Guarantor. The Company, CSK Corp. and the Subsidiary Guarantor shall
bear their internal expenses (including, without limitation, all salaries and
expenses of their officers and employees performing legal, accounting or other
duties), the expenses of any annual audit and other auditor fees and expenses
and the fees and expenses of any Person, including special experts, retained by
the Company, CSK Corp. and the Subsidiary Guarantor. Notwithstanding the
provisions of this Section 4, each Holder shall bear the expense of any broker's
commission, agency fee and underwriter's discount or commission (including,
without limitation, the expenses related to the engagement of a "qualified
independent underwriter"), if any, relating to the sale or disposition of such
Holder's Transfer Restricted Securities pursuant to a Shelf Registration
Statement.

            5. Indemnity and Contribution.

            (a) Each of the Company, CSK Corp. and the Subsidiary Guarantor
agree to indemnify and hold harmless each Holder of Transfer Restricted
Securities named in any Shelf Registration Statement (including, without
limitation, the Initial Purchasers), and each person, if any, who controls any
such Holder within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act (collectively referred to for purposes of this
Section 5 as a "HOLDER"), from and against any and all losses, claims, damages
and liabilities (including without limitation the reasonable legal fees and
other expenses incurred in connection with any suit, action or proceeding or any
claim asserted) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Shelf Registration Statement, or in any
Prospectus, or any amendment thereof or supplement thereto, or caused by any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary, in the case of any Prospectus, in light of the
circumstances under which they were made, to make the statements therein not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with information relating to
any Holder furnished to the


                                       14
<PAGE>
Company, CSK Corp. or the Subsidiary Guarantor in writing by such Holder
expressly for use therein; provided that the foregoing indemnity with respect to
any Shelf Registration Statement, or any Prospectus, shall not inure to the
benefit of any Holder (or the benefit of any person controlling such Holder)
from whom the person asserting any such losses, claims, damages or liabilities
purchased the securities concerned, to the extent that any such loss, claim,
damage or liability of the Holders occurs under the circumstance where it shall
have been established that (w) the Company, CSK Corp. or the Subsidiary
Guarantor had previously furnished copies of the Prospectus, and any amendments
and supplements thereto, to the Holder (to the extent such Holder has previously
requested such copies), (x) delivery of the Prospectus, and any amendment or
supplements thereto, was required by the Securities Act to be made to such
person, (y) the untrue statement or omission of a material fact was corrected in
the Prospectus or amendments or supplements thereto, and (z) there was not sent
or given to such person, at or prior to the written confirmation of the sale of
such securities to such person, a copy of such Prospectus or amendments or
supplements thereto.

            (b) Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, CSK Corp., the Subsidiary Guarantor, the directors
and officers of each of the Company, CSK Corp. and the Subsidiary Guarantor and
each person who controls the Company, CSK Corp. or the Subsidiary Guarantor
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act, to the same extent as the foregoing indemnity from the Company,
CSK Corp. and the Subsidiary Guarantor to the Holders, but only with reference
to information relating to such Holder furnished to the Company and CSK Corp. in
writing by such Holder expressly for use in the Shelf Registration Statement, or
in any Prospectus, or any amendment or supplement thereto.

            (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such person (the "INDEMNIFIED PERSON") shall promptly
notify the person against whom such indemnity may be sought (the "INDEMNIFYING
PERSON") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may designate in such proceeding and shall pay the
reasonable fees and expenses of such counsel related to such proceeding. In any
such proceeding, any Indemnified Person shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Person unless (i) the Indemnifying Person and the Indemnified
Person shall have mutually agreed to the contrary, (ii) the Indemnifying Person
has failed within a reasonable time to retain counsel reasonably satisfactory to
the Indemnified Person or (iii) the named parties in any such proceeding
(including any impleaded parties) include both the Indemnifying Person and the
Indemnified Person and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them. It
is understood that the Indemnifying Person shall not, in connection with any
proceeding or related proceeding in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all Indemnified Persons, and that all such fees and expenses shall
be reimbursed as they are incurred. Any such separate firm for the Holders and
such control persons of the Holders shall be designated in writing by the
Initial Purchasers and any such separate firm for the Company, CSK Corp. and the
Subsidiary Guarantor, the directors and


                                       15
<PAGE>
officers of each of the Company, CSK Corp. and the Subsidiary Guarantor and such
control persons of the Company, CSK Corp. and the Subsidiary Guarantor shall be
designated in writing by the Company. The Indemnifying Person shall not be
liable for any settlement of any pending or threatened proceeding effected
without its prior written consent, but if settled with such consent or if there
be a final judgment for the plaintiff, the Indemnifying Person agrees to
indemnify in accordance with Section 5(a) or 5(b) above, as the case may be, any
Indemnified Person from and against any loss or liability by reason of such
settlement or judgment. No Indemnifying Person shall, without the prior written
consent of the Indemnified Person, effect any settlement of any pending
proceeding in respect of which any Indemnified Person is a party or of any
threatened proceeding in respect of which any Indemnified Person could have been
a party and indemnity could have been sought hereunder by such Indemnified
Person, unless such settlement includes an unconditional release of such
Indemnified Person from all liability on claims that are the subject matter of
such proceeding on terms reasonably satisfactory to such Indemnified Person.

            (d) If the indemnification provided for in paragraph (a) or (b) of
this Section 5 is unavailable to an Indemnified Person or insufficient in
respect of any losses, claims, damages or liabilities referred to therein, then
each Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company, CSK Corp. and the Subsidiary Guarantor on the
one hand and the Holder on the other hand with respect to the sale by such
Holder of Securities or Common Stock 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, CSK Corp. and the Subsidiary
Guarantor on the one hand and of such Holder on the other in connection with the
statements or omissions that resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. Benefits
received by the Company, CSK Corp. and the Subsidiary Guarantor shall be deemed
to be equal to the total net proceeds from the Initial Placement (before
deducting expenses). Benefits received by the Initial Purchasers shall be deemed
to be equal to the total purchase discounts and commissions received by the
Initial Purchasers in the Initial Placement, and benefits received by any other
Holders shall be deemed to be equal to the value of having the Securities
registered under the Securities Act. Benefits received by any underwriter shall
be deemed to be equal to the total underwriting discounts and commissions, as
set forth on the cover page of the Prospectus forming a part of the Shelf
Registration Statement which resulted in such losses, claims, damages or
liabilities. The relative fault of the Company, CSK Corp. and the Subsidiary
Guarantor on the one hand and such Holder on the other shall be determined by
reference to, among other things, whether any untrue or any 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, CSK Corp., the
Subsidiary Guarantor or by such Holder and the parties' relevant intent,
knowledge, information and opportunity to correct or prevent such statement or
omission.

            (e) The Company, CSK Corp., the Subsidiary Guarantor and the Holders
agree that it would not be just and equitable if contribution pursuant to this
Section 5 were determined by pro rata allocation (even if the Holders were
treated as one entity for such purpose) or any other method of allocation that
does not take account of the equitable


                                       16
<PAGE>
considerations referred to in paragraph (d) of this Section 5. The amount paid
or payable by an Indemnified Person as a result of losses, claims, damages and
liabilities referred to in paragraph (d) of this Section 5 shall be deemed to
include, subject to the limitations set forth above, any reasonable legal or
other expenses incurred by such Indemnified Person not otherwise reimbursed in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 5, in no event shall any Holder
be required to contribute any amount in excess of the amount by which the total
amount received by such Holder with respect to its sale of Transfer Restricted
Securities pursuant to a Shelf Registration Statement exceeds the amount of any
damages that such Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.

            (f) The remedies provided for in this Section 5 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any Indemnified Party at law or in equity.

            (g) The indemnity and contribution agreements contained in this
Section 5 shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of any Holder or any person controlling any Holder or by or on behalf of the
Company, CSK Corp. and the Subsidiary Guarantor, the officers or directors of
each of the Company, CSK Corp. and the Subsidiary Guarantor or any other person
controlling the Company, CSK Corp. or the Subsidiary Guarantor and (iii) the
sale by a Holder of Transfer Restricted Securities covered by a Shelf
Registration Statement.

            6. Rules 144 and 144A. Each of the Company and CSK Corp. covenant
that they shall file the reports required to be filed by it under the Securities
Act and the Exchange Act in a timely manner so long as the Transfer Restricted
Securities remain outstanding. If at any time either the Company or CSK Corp. is
not required to file such reports, it will, upon request of any Holder or
beneficial owner of Transfer Restricted Securities, make available such
information necessary to permit sales pursuant to Rule 144A. Each of the Company
and CSK Corp. further covenant that, for as long as any Transfer Restricted
Securities remain outstanding, it will take such further action as any Holder of
Transfer Restricted Securities may reasonably request, all to the extent
required from time to time to enable such Holder to sell Transfer Restricted
Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144 and Rule 144A. Upon the written request
of any Holder of Transfer Restricted Securities, the Company shall deliver to
such Holder a written statement as to whether it has complied with such
requirements. Nothing in this Section 6 shall be deemed to require the Company,
CSK Corp. or the Subsidiary Guarantor to register any of its securities under
the Exchange Act.

            7. Underwritten Offering.

            (a) If any of the Transfer Restricted Securities covered by any
Shelf Registration Statement are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will
administer the underwritten offering will


                                       17
<PAGE>
be selected by the Majority Holders of such Transfer Restricted Securities
included in such underwritten offering, subject to the consent of the Company
and CSK Corp. (which shall not be unreasonably withheld or delayed), and such
Holders shall be responsible for all underwriting commissions and discounts in
connection therewith; provided, however, that notwithstanding anything contained
in this Agreement to the contrary, none of the Company, CSK Corp. or the
Subsidiary Guarantor shall be under any obligation to participate in any
underwritten offering with respect to the Transfer Restricted Securities and no
underwritten offering shall be effected pursuant to this Agreement without the
prior written consent of the Company and CSK Corp.

            (b) No Holder may participate in any underwritten offering hereunder
unless such person (i) agrees to sell such Holder's Transfer Restricted
Securities on the basis reasonably provided in any underwriting arrangements
approved by the Holders entitled hereunder to approve such arrangements and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

            (c) In the case of the underwritten offering provided by this
Section 7, take all actions reasonably necessary, or reasonably requested by the
holders of a majority of the Transfer Restricted Securities being sold in such
underwritten offering, in order to expedite or facilitate disposition of such
Transfer Restricted Securities; provided that none of the Company, CSK Corp. or
the Subsidiary Guarantor shall be required to take any action in connection with
the underwritten offering without its consent.

            8. Miscellaneous.

            (a) No Inconsistent Agreements. None of the Company, CSK Corp. or
the Subsidiary Guarantor has, as of the date hereof, entered into nor shall it,
on or after the date hereof, enter into, any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders herein or
otherwise conflicts with the provisions hereof. In addition, none of the
Company, CSK Corp. or the Subsidiary Guarantor shall grant to any of its
securityholders the right to include any of its securities in the Shelf
Registration Statement provided for in this Agreement other than the Transfer
Restricted Securities.

            (b) Amendments and Waivers. Except as provided in the next
paragraph, this Agreement, including this Section 8(b), may be amended, modified
or supplemented, and waivers or consents to depart from the provisions hereof
may be given, only by the written consent of the Company, CSK Corp. and the
Subsidiary Guarantor and the majority of the Holders of the then outstanding
Transfer Restricted Securities; provided that with respect to any matter that
directly or indirectly affects the rights of the Initial Purchasers hereunder,
the Company shall obtain the written consent of the Initial Purchasers against
which such amendment, supplement, waiver or consent is to be effective.
Notwithstanding the foregoing (except the foregoing proviso), a waiver or
consent to depart from the provisions hereof with respect to a matter that
relates exclusively to the rights of Holders whose Transfer Restricted
Securities are being sold pursuant to a Shelf Registration Statement and that
does not directly or indirectly affect the rights of other Holders may be given
