                              AMENDED AND RESTATED
                              EMPLOYMENT AGREEMENT


        This Amended and Restated Employment Agreement (the "Amended Agreement")
is made and entered into as of the __ day of June, 2002, by and among Big 5
Sporting Goods Corporation, a Delaware corporation (the "Company"), Big 5 Corp.,
a Delaware corporation and wholly owned subsidiary of the Company ("Big 5
Corp."), and Robert W. Miller, an individual (the "Executive").

                                 R E C I T A L S

        A. Executive is currently employed as Chairman of the Company's Board of
Directors (the "Board") and as Chairman of Big 5 Corp.'s Board of Directors
pursuant to an Employment Agreement (the "Employment Agreement") between Big 5
Corp's predecessor and Executive dated as of January 1, 1993.

        B. The Company, Big 5 Corp. and Executive desire to amend and restate
the Employment Agreement regarding the terms and conditions of Executive's
employment by the Company and Big 5 Corp.

                                A G R E E M E N T

        NOW, THEREFORE, in consideration of the foregoing recitals and the
terms, covenants and conditions contained herein, the Company and Big 5 Corp.
hereby agree to employ Executive, and Executive hereby accepts and agrees to
such employment, on the terms and subject to the conditions set forth herein.

        1. TERM OF EMPLOYMENT. This Amended Agreement shall be effective as of
the Effective Date (as defined in Section 8.1) and shall govern Executive's
employment from and after such date. As of any given date after the Effective
Date (each such date, the "Date of Determination"), Executive's employment shall
terminate on the third anniversary of the Date of Determination, unless sooner
terminated in accordance with the provisions of this Amended Agreement or
extended by an amendment executed by the Company, Big 5 Corp. and Executive (the
"Term"). Accordingly, there shall always for all purposes be a minimum of at
least three years remaining on the Term under this Amended Agreement.

        2. CAPACITY AND DUTIES. Executive shall be employed as Chairman Emeritus
of the Board, with such duties and responsibilities as may be mutually agreed on
by Executive and the Chief Executive Officer of the Company. Effective upon the
effectiveness of this Amended Agreement, Executive will resign any and all other
positions he may hold with the Company and Big 5 Corp. Executive shall
thereafter provide advisory and other services to the Company. As long as
Executive serves as Chairman Emeritus of the Company, the Company shall use its
best efforts to ensure that Executive shall continue to be elected to serve on
the Board.

        3. COMPENSATION.

               3.1 SALARY. During the Term, Executive's annual salary shall be
Three Hundred Fifty Thousand Dollars ($350,000) (the "Annual Salary").

               3.2 PAYMENT OF TAXES. Except as explicitly provided herein, to
the extent that any taxes become payable by Executive by virtue of any payments
made or benefits conferred by the Company, the Company shall not be liable to
pay or obligated to reimburse Executive for any such taxes or to make any
adjustment under this Amended Agreement. Any payments otherwise due hereunder to
Executive, including but not limited to the Annual Salary, shall be reduced by
any required withholding for federal, state and/or local taxes and other
appropriate payroll deductions.

        4. BENEFITS.

               4.1 EXPENSES. The Company agrees to repay or reimburse Executive
for ordinary and necessary business expenses to the extent compatible with, and
subject to the verification and substantiation documentation and procedures
applicable under, the Company's general policies for its senior executive
officers.

               4.2 MEDICAL AND INSURANCE BENEFITS. During the Term, the Company
shall provide Executive with those group medical, health insurance, disability
insurance and life insurance benefits generally available to its senior
executive officers, as such benefits may be modified from time to time in the
Company's sole and absolute discretion.

               4.3 VACATION AND SICK LEAVE. During the Term, Executive shall be
entitled to vacations, holidays and sick leave without reduction in Executive's
Annual Salary on a basis consistent with the policies established from time to
time by the Company for its senior executive officers in its sole and absolute
discretion.

               4.4 AUTOMOBILE. During the Term, the Company shall provide
Executive with an automobile on a basis consistent with the policies established
from time to time by the Company for its senior executive officers in its sole
and absolute discretion.

               4.5 401(k) AND PROFIT-SHARING PLAN. During the Term, the Company
shall provide Executive with the opportunity to participate in the Company's
401(k) plan and profit-sharing plan on a basis consistent with the policies
established from time to time by the Company for its senior executive officers
in its sole and absolute discretion.

               4.6 OTHER BENEFITS. Executive shall also be eligible, on a basis
consistent with the policies established by the Company for its senior executive
officers, for any other benefits provided generally by the Company for or to its
senior executive officers.

        5. TERMINATION.

               5.1 TERMINATION BY EITHER PARTY FOR ANY REASON. Each of the
Company and Executive shall have the right to terminate Executive's employment
under this Amended Agreement at any time for any reason or for no reason by
written notice to the other party and Executive's employment shall automatically
terminate upon Executive's



                                      -2-
<PAGE>
death (each such event, a "Termination" and the date on which Executive's
employment is terminated, the "Termination Date"). In the event of Termination,
this Amended Agreement shall terminate immediately and both parties shall
thereupon be released and discharged of and from all further obligations
hereunder except that any provisions that by their nature survive termination
shall so survive (including the Company's ongoing obligations pursuant to
Section 5.2 and, if applicable, Executive's ongoing obligations pursuant to
Sections 6.1 and 6.2) and the Company shall pay to Executive (or Executive's
estate), on the Termination Date, all amounts accrued and unpaid as of the
Termination Date in respect of (i) Executive's Annual Salary for services
rendered through such date, (ii) vacation pay to the extent consistent with the
Company's policies in effect as of the Termination Date regarding entitlement to
payment in respect of accrued but unused vacation time and (iii) expenses owing
to Executive pursuant to Section 4.1.

               5.2 RETIREMENT BENEFITS. In recognition of Executive's 46 years
of service to the Company, the Company shall also pay to Executive, on the fifth
business day following the Termination Date and on each anniversary of the
Termination Date thereafter, as a lump sum payment subject to Section 3.2, a
payment equal to Executive's Annual Salary (each, a "Retirement Payment"). In
the event Florence H. Miller, Executive's spouse (the "Spouse"), survives
Executive, the Company shall make the Retirement Payments to Spouse for the
remainder of her lifetime. In addition, the Company shall continue to provide
for the benefit of Executive and Spouse the medical and insurance benefits
referred to in Section 4.2 during their respective lifetimes; provided, however,
if certain of the Company's medical and insurance programs prohibit inclusion of
Executive or Spouse under such programs, the Company will pay Executive or
Spouse, as the case may be, an amount of cash (on a grossed up basis to account
for the impact of taxes) sufficient to procure benefits comparable to those that
would otherwise be provided pursuant to Section 4.2, up to an aggregate of
$25,000 per year.

               5.3 EXCLUSIVITY OF REMEDIES. Executive agrees that the rights and
entitlements set forth in Section 5 apply to the exclusion of any other
contractual rights and entitlements that Executive may have from the Company or
Big 5 Corp. by reason of the termination of Executive's employment.

               5.4 NO MITIGATION. The payments required to be paid to Executive
by the Company pursuant to Section 5 shall not be reduced or mitigated by
amounts which Executive is capable of earning or does earn during any period
following his Termination Date.

        6. COVENANTS.

               6.1 NON-INTERFERENCE COVENANT. Upon the termination of the
employment relationship between the Company and Executive for any reason,
whether upon the expiration of the Term or earlier, and for a period of two
years thereafter (the "Non-Solicitation Period"), Executive agrees to refrain
from, directly, indirectly or as an agent on behalf of or in conjunction with
any person, firm, partnership, corporation or other entity, soliciting or
encouraging any employee of the Company or its direct or indirect subsidiaries
who is employed in an executive, managerial, administrative or professional
capacity or who


                                      -3-
<PAGE>
possesses Confidential Material (as defined in Section 6.2), to leave the
employment of the Company or its affiliated entities.

               6.2 NONDISCLOSURE OF CONFIDENTIAL MATERIAL.

                      (a) In the performance of his duties, Executive has
previously had, and may be expected in the future to have, access to
confidential records and information, including, but not limited to,
development, marketing, purchasing, organizational, strategic, financial,
managerial, administrative, manufacturing, production, distribution and sales
information, data, specifications and processes presently owned or at any time
hereafter developed by the Company or its agents or consultants or used
presently or at any time hereafter in the course of its business, that are not
otherwise part of the public domain (collectively, the "Confidential Material").
All such Confidential Material is considered secret and has been and/or will be
disclosed to Executive in confidence. Except in the performance of his duties to
the Company, Executive shall not, directly or indirectly for any reason
whatsoever, disclose or use any such Confidential Material, except that the
foregoing disclosure prohibition shall not apply as to Confidential Material
that has been publicly disclosed (not due to a breach by Executive of his
obligations hereunder or by breach of any other person of a confidential,
fiduciary or confidential obligation, the breach of which Executive knows or
reasonably should know). All records, files, drawings, documents, equipment and
other tangible items, wherever located, relating in any way to the Confidential
Material or otherwise to the Company's business, which Executive has prepared,
used or encountered or shall in the future prepare, use or encounter, shall be
and remain the Company's sole and exclusive property and shall be included in
the Confidential Material. Upon termination of this Amended Agreement, or
whenever requested by the Company, Executive shall promptly deliver to the
Company any and all of the Confidential Material and copies thereof, not
previously delivered to the Company, that may be, or at any previous time has
been, in the possession or under the control of Executive.

                      (b) In light of the fact that the Confidential Material
that Executive has acquired, and will acquire, is inextricably bound with
Executive's knowledge regarding the conduct of the Company's business activities
and that therefore Executive would necessarily use Confidential Material if he
were to compete with the Company, Executive further agrees that during the term
of Executive's employment relationship with the Company, he will not provide any
services, whether as an officer, director, proprietor, employee, partner,
consultant, advisor, agent, sales representative or otherwise, nor will he own
beneficially securities of any entity (except that, in the case of any entity
whose equity securities are publicly-held, he may beneficially own up to 2% of
the outstanding equity securities of such entity) that, directly or indirectly,
competes with any of the Company's present or future (up to the date of
termination) business activities. Executive further agrees that, upon the
termination of the employment relationship between the Company and Executive for
any reason, whether upon the expiration of the Term or earlier (including a
voluntary termination by Executive), the restrictions set forth in the previous
sentence shall extend for the greater of (x) a six-month period after
termination and (y) the remainder of the Term as then in effect (without any
further extensions thereof) but for such termination.

               6.3 EQUITABLE RELIEF. Executive acknowledges that violation of
either Section 6.1 or 6.2 would cause the Company irreparable damage for which
the Company



                                      -4-
<PAGE>
cannot be reasonably compensated in damages in an action at law, and therefore
in the event of any breach by Executive of Section 6.1 or 6.2, the Company shall
be entitled to make application to a court of competent jurisdiction for
equitable relief by way of injunction or otherwise (without being required to
post a bond). This provision shall not, however, be construed as a waiver of any
of the rights which the Company may have for damages under this Amended
Agreement or otherwise, and all of the Company's rights and remedies shall be
unrestricted.

        7. ARBITRATION AS THE EXCLUSIVE REMEDY.

               7.1 ARBITRATION OF ALL DISPUTES. If Executive and the Company
cannot resolve a dispute (whether arising in contract or tort or any other legal
theory and whether based on federal, state or local statute or common law and
regardless of the identities of any other defendants) that in any way relates to
or arises out of the employment relationship established herein or the
termination thereof (a "Dispute"), then arbitration will be used to settle such
Dispute. Because arbitration is generally faster and less expensive than other
procedures for resolving disputes, both Executive and the Company agree that the
arbitration procedure set forth below will be their exclusive remedy and waive
any right to seek legal relief in any other form. In the event that a Dispute
involves a claim which either Executive or the Company seeks to assert against a
third party, the assertion of such claim against such third party in a court or
other tribunal shall not relieve Executive and the Company from their respective
obligations to resolve the Dispute between them by arbitration under Section 7.
The parties further agree that arbitration shall be their exclusive remedy in
the event of any Dispute which involves any third party (including any officer,
director or agent of the Company or an affiliate of the Company) provided that
such third party consents to participate in and be bound by such arbitration.
The only exception to the preceding provisions of Section 7.1 is that the
Company may seek provisional relief from any court having jurisdiction in the
event of an alleged breach by Executive of Sections 6.1 or 6.2 or any other
provision of this Amended Agreement pending a final determination by
arbitration, in the event of any claim that would be rendered ineffectual
without provisional relief and Executive may seek such provisional relief,
pending a final determination by arbitration, in the event of any claim that
would be rendered ineffectual without provisional relief. The arbitration will
be conducted in accordance with the employment arbitration procedures of the
American Arbitration Association ("AAA"), except as modified in this Amended
Agreement.

               7.2 SELECTION OF ARBITRATORS. Each party shall have the right to
designate one arbitrator within ten (10) business days from the date when the
party initiating the arbitration files and delivers a notice of intent to
arbitrate. If, within that time period, either party has failed to appoint an
arbitrator, AAA shall make the appointment. The two arbitrators shall agree upon
and designate a third arbitrator within ten (10) business days from the date of
the appointment of the last-appointed arbitrator. In the event that the two
arbitrators have not designated a third arbitrator within ten (10) business days
from the date of the appointment of the last-appointed arbitrator, AAA shall
appoint the third arbitrator. After the selection of arbitrators, the parties
may mutually agree to used the third arbitrator as the sole arbitrator to
resolve their dispute.


                                      -5-
<PAGE>
               7.3 PROCEDURES. The party filing a claim must present it in
writing to both the other party and the AAA office in Los Angeles within six
months of the date the party filing the claim knew or should have known of it or
the Termination Date, whichever is earlier. Any claim not brought within the
required time period will be waived forever. In the arbitration proceedings (i)
all testimony of witnesses shall be taken under oath, (ii) it is specifically
contemplated and agreed by the parties hereto that the provisions of Section
1283.05 of the Code of Civil Procedure, as presently in force, be incorporated
into and made a part of, and be applicable to, the arbitration agreement set
forth in this Section 7.3, and (iii) upon conclusion of any arbitration
proceedings hereunder, the arbitrators shall render findings of fact and
conclusions of law in a written opinion setting forth the basis and reasons for
any decision reached and deliver such documents to each party to this Amended
Agreement along with a signed copy of the award in accordance with Section
1283.6 of the California Code of Civil Procedure.

                      Each party hereby agrees that the prevailing party shall
be entitled to recover all costs incurred in preparation for and as a result of
any such arbitration, including without limitation, filing fees, attorneys'
fees, the compensation to be paid to the arbitrators in any such arbitration and
costs of transcripts. The arbitrators shall not have power or competence to
allocate between the parties in their award any such costs, expenses, fees or
share of the arbitrators' compensation, except as provided in the preceding
sentence.

        8. MISCELLANEOUS.

               8.1 EFFECTIVE DATE. The "Effective Date" of this Amended
Agreement shall be the consummation of the initial public offering of Common
Stock contemplated by the registration statement on Form S-1 filed with the
Securities and Exchange Commission on August 21, 2001 (File No. 333-68094) (the
"IPO"). If the IPO has not been consummated by August 31, 2002, this Amended
Agreement shall terminate and be of no further force and effect. The Employment
Agreement shall remain in full force and effect until this Amended Agreement
becomes effective.

               8.2 JOINT AND SEVERAL OBLIGATIONS. The obligations and promises
set forth herein by the Company and Big 5 Corp., including payment obligations,
shall be joint and several undertakings of each such party, and, in the event of
a breach of any of such obligations or promises, Executive may proceed hereunder
against any one or more of such parties without waiving the right to proceed
against the other.

               8.3 AGREEMENT AUTHORIZED. Executive hereby warrants that
Executive is free to enter into this Amended Agreement and to render Executive's
services pursuant hereto. The Company and Big 5 Corp. hereby warrant that any
required authorization of this Amended Agreement by their respective boards of
directors have been obtained.

               8.4 COUNSEL. Executive has read and understands this Amended
Agreement and has sought the advice of counsel to the extent he has determined
appropriate.

               8.5 PARTIAL INVALIDITY. If any term or provision of this Amended
Agreement or the application thereof to any person or circumstance shall, to any
extent, be invalid or unenforceable (other than provisions going to the essence
of this Amended



                                      -6-
<PAGE>
Agreement), the remainder of this Amended Agreement, or the application of such
term or provision to persons or circumstances other than those as to which it is
held invalid or unenforceable, shall not be affected thereby, and each such term
and provision of this Amended Agreement shall be valid and be enforced to the
fullest extent permitted by law.
