the interests of the Company and its affiliates and to aid in the integration of
the Company's business and operations with those of Heafner and its affiliates.
Executive shall report to the Chief Executive Officer of Heafner or such other
person as the Board may designate from time to time. As used herein, the phrase
"Term of Employment" shall mean the period commencing on the Effective Date and
ending on the third anniversary of the Effective Date.

            3. Compensation.

                  (a) Base Salary. During the Term of Employment, the Company
agrees to pay to Executive a salary at the rate of $145,385 per annum, payable
in bi-weekly installments or otherwise in accordance with the normal payroll
procedures of the Company. Such annual salary shall be subject to annual review
and may be adjusted upward from time to time in the sole discretion of the

                  (b) Bonuses. (i) Executive shall be entitled to receive from
the Company a bonus (the "Stay Put Bonus") in the amount of $600,000, payable in
two installments as follows: $300,000 on the one-year anniversary of the
Effective Date, $200,000 on the two-year anniversary of the Effective Date and

      excess. Such bonus shall be paid in quarterly installments commencing on

      that, if the quarterly figures necessary to calculate the Executive's
      Incentive Bonus for the period in which the Effective Date falls or any
      prior period are not yet available as of the Effective Date, the
      Executive's Incentive Bonus for such period shall be calculated on the
      basis of estimated quarterly figures and subsequent Incentive Bonus
      payments shall be adjusted to the extent necessary based on actual
      quarterly figures for the period in question.

            (B) The Incentive Bonus for the 12-month period ending on the second
      anniversary of the Effective Date shall be in an amount determined
      pursuant to a formula agreed to in advance by the Board and Executive.
      Such bonus shall be paid in accordance with normal bonus practices adopted
      by the Company from time to time.

                  (iv) On the one-year anniversary of the Effective Date,

                  (ii) If, as a result of Executive's incapacity due to physical
or mental illness (as determined in good faith by a physician acceptable to the
Company and the Executive), Executive shall have been unable to perform the
essential functions of his position with the Company for 90 days during any
twelve (12) month period or if a physician acceptable to the Company advises the
Company that it is likely that Executive will be unable to perform the essential
functions of his position for 90 days during the 


                                      -5-

      Salary during the Term of Employment;

                  (iv) the modification of the position and responsibilities of

Period (as defined in Section 6).

            6. Confidential Information; Non-Competition.

                  (a) Confidential Information. (i) Executive recognizes and
hereby acknowledges that, as a senior executive of the Company, he will learn
of, and be exposed to, confidential business information concerning the Company
Group's information, ideas, know how, trade secrets, processes, computer
software, methods, practices, techniques, technical plans, customer lists,
pricing techniques and information, marketing plans, financial information, and
all other compilations of information that relate to the Company Group's
business and its current and prospective customers ("Confidential Information").
Executive recognizes and hereby acknowledges that such Confidential Information
is a valuable asset of the Company Group. Executive agrees to safeguard such
Confidential Information for the exclusive benefit of the Company Group and
agrees that he will not disclose, distribute or publish such Confidential
Information to any person, company, business or corporation, provided that
Confidential Information shall not include information that is or becomes
generally available to the public (other than as a result of a disclosure in
violation of this Agreement by Executive or by a person who received such
information from Executive in violation of this Agreement). "Company Group"
means the Company, Heafner and their respective subsidiaries and affiliates.

                        (ii) Executive agrees that he will promptly and fully
disclose to the Company all inventions, ideas, software, trade secrets or
know-how (whether patentable or copyrightable or not) made or conceived by
Executive (either solely or jointly with others) and all tangible work product
derived therefrom (collectively, the "Ideas") during the period in which
Executive is employed under this Agreement. Executive agrees that all such Ideas
shall be and remain the sole and exclusive property of the Company. On the
request of the Company, Executive shall, during and after the Term of
Employment, without charge to the Company but at the expense of the Company,
assist the Company in any reasonable way to vest in the Company title to all
such Ideas, and to obtain any patents, trademarks or copyrights thereon in all
countries throughout the world. In this regard, the parties shall executive and
deliver any and all documents that the Company may reasonably request.

                  (b) Use of Confidential Information for Another Employer.
Executive acknowledges and recognizes his possession of Confidential Information
and acknowledges the highly competitive nature of business of the Company Group.


                                      -7-
   8

Accordingly, in order further to protect the Confidential Information of the
Company Group from disclosure or use, Executive agrees that, during the period
commencing on the Effective Date and ending on the later of (i) the third
anniversary of the Effective Date and (ii) the one-year anniversary of the
effective date of termination of Executive's employment with the Company (the
"Covenant Period"), he will not, for any reason whatsoever, either individually
or as an officer, director, stockholder, partner, agent or principal or another
business or firm, (i) directly or indirectly engage in the States of Arizona,
California, New Mexico, Nevada, Oregon, Utah and Washington in any Competing
Business, or (ii) assist others in engaging in any Competing Business in the
manner described in clause (i). "Competing Business" means any business that is
competitive with the business of the members of the Company Group (including,
without limitation, the wholesale or retail tires or automotive parts
businesses).

                  (c) Solicitation of Customers. Executive agrees that during
the course of his employment with the Company, he will learn of and be exposed
to confidential business information and trade secrets of the Company Group
concerning the Company Group's customers. Executive further agrees that, should
he seek to divert, take away, or solicit any of the customers of the Company
Group with respect to which he has learned and/or been exposed to such
confidential information, he will of necessity make use of or disclose such
confidential information, to the irreparable detriment of the Company Group.
Accordingly, Executive promises that, during the Covenant Period, he will not,
directly or indirectly, either for himself or for any other person, firm,
company or corporation, divert, take away or solicit, or attempt to divert, take
away or solicit any businesses or individuals that were customers of the Company
Group during the period in which Executive was employed by the Company.

                  (d) Solicitation of Employees. Executive agrees and
acknowledges that the Company Group has expended large sums in the recruitment,
training and development of its employees and that the continued employment of
such persons by the Company Group constitutes a substantial benefit to the
Company Group. Executive further agrees and acknowledges that the business of
the Company Group could be severely disrupted and injured in the event that
another person, firm, company or corporation were to attempt to induce any or
all of the Company Group's employees to terminate their employment with the
Company Group. Accordingly, Executive promises and covenants that, during the
Covenant Period, he will not, directly or indirectly, either for himself or for
any other person, firm, company or corporation, contact or communicate with any
employee of any member of the Company Group for the purpose of inducing or
otherwise encouraging such employee to terminate his or her employment with the
Company, provided, however, that this Section 6(d) shall not preclude the
Executive from giving an employment reference at the request of a prospective
employer of such employee.

                  (e) Acknowledgment. Executive acknowledges that he is entering
into the covenants contained in this Section 6, inter alia, due to his status as
a


                                      -8-
   9

signatory to the Stock Purchase Agreement and his position, prior to the
Effective Date, as a stockholder of the Company.

            7. Miscellaneous. This Agreement shall also be subject to the
following provisions:

                  (a) It is the desire and intent of the parties hereto that the
provisions of this Agreement shall be enforced to the fullest extent permissible
under the laws and public policies applied in each jurisdiction in which
enforcement is sought. Accordingly, although Executive and the Company consider
the restrictions contained in this Agreement to be reasonable for the purposes
of preserving the Company Group's goodwill and proprietary rights, if any
particular provision of this Agreement shall be adjudicated to be invalid or
unenforceable, such provision shall be deemed amended to delete therefrom the
portion thus adjudicated to be invalid or unenforceable, such deletion to apply
only with respect to the operation of such provision in the particular
jurisdiction in which such adjudication is made. It is expressly understood and
agreed that although the Company and Executive consider the restrictions
contained in Section 6 to be reasonable, if a final determination is made by a
court of competent jurisdiction that the time or territory or any other
restriction contained in this Agreement is unenforceable against Executive or
Company, the provisions of this Agreement shall be deemed amended to apply as to
such maximum time and territory and to such maximum extent as such court may
judicially determine or indicate to be enforceable.

                  (b) The parties acknowledge that the Company's damages at law
would be an inadequate remedy for the breach by Executive of any provision of
Section 6, and agree in the event of such breach that the Company may obtain
temporary and permanent injunctive relief restraining Executive from such
breach, and, to the extent permissible under the applicable statutes and rules
of procedure, a temporary injunction may be granted immediately upon the
commencement of any such suit. Nothing contained in this Agreement shall be
construed as prohibiting the Company from pursuing other remedies available at
law or equity for such breach or threatened breach of Section 6 of this
Agreement.

                  (c) Executive represents and warrants to the Company that he
has the authorization, power and right to deliver, execute, and fully perform
his obligations under this Agreement in accordance with its terms. The Company
has the authorization, power and right to deliver, execute and fully perform its
obligations under this Agreement in accordance with its terms.

                  (d) This Agreement contains a complete statement of all the
arrangements between the parties with respect to Executive's employment by the
Company; this Agreement supersedes all prior and existing negotiations and
agreements concerning Executive's employment; and this Agreement can only be
changed or modified pursuant to a written instrument duly executed by each of
the parties hereto.

such withholding taxes and deductions as may be required by law.

benefit of the successors and permitted assigns of the Company, provided that
the Company shall not assign this Agreement to any person or entity other than
an affiliate of the Company without the prior written consent of Executive.
Except as expressly provided herein, Executive may not sell, transfer, assign,
or pledge any of his rights or interests pursuant to this Agreement. This
Agreement is for the sole benefit of the parties hereto and not for the benefit
of any third party, provided that the parties agree that Heafner shall be an
intended third party beneficiary of all of the provisions of this Agreement,
including, without limitation, the covenants contained in Section 6 and Section
7(h).

                        Exhibit B to Employment Agreement

                               SYNERGY BONUS PLAN

Executive shall be entitled to be paid a Synergy Bonus pursuant to the terms set
forth in this Exhibit B. For purposes of calculating Executive's Synergy Bonus,
if any, targeted EBITDA of the Company shall be $6,400,000 for the 12-month
period ending on the one-year anniversary of the Effective Date (the "Target
Period"). The actual EBITDA calculations shall be made on a pro forma basis
without giving effect to any acquisitions or dispositions of assets, stock or
businesses by the Company occurring during the Target Period or to the
acquisition by Phoenix of the Arizona Business (as defined in the Stock Purchase
Agreement), and shall be adjusted to the extent necessary in accordance with
Section 3.11(a) of the Stock Purchase Agreement. These pro forma actual EBITDA
calculations shall be subject to the approval of the Board acting in good faith.
The Company shall pay to Executive the amount, if any, due to Executive as
Synergy Bonus promptly upon the Company's receipt of the Company's accountant's
opinion with respect to the Company's financial statements for the Target Period
(but in no event later than 120 days after the end of such Target Period).

The amount of the Synergy Bonus, if any, shall be equal to (i) the sum of (A) 85
percent of 50 percent of the excess of actual EBITDA during the Target Period
over targeted EBITDA plus (B) 85 percent of 50 percent of the amount of any net
cost savings achieved with respect to members of the Company Group (other than
the Company) during the Target Period (1) that are the identifiable result of
any potential cost savings described on Schedule I attached to this Exhibit B
and (2) that otherwise result from the transactions contemplated by the Stock
Purchase Agreement (as determined in good faith by the Board of Directors of
Heafner, which determination shall be open to good faith dispute by the
Executive in accordance with the arbitration provisions contained in Exhibit C)
minus (ii) the amount of any reductions made in accordance with Section
3(b)(iii)(A).

For purposes of calculating the Synergy Bonus, (x) the Company shall be
accounted for on a stand-alone basis using the accounting principles applied in
preparing the Closing Date Balance Sheet (as defined in the Stock Purchase
Agreement) and (y) no corporate-level overhead costs incurred by Heafner shall
be allocated to the Company.

"EBITDA" shall mean earnings before interest, taxes, depreciation and
amortization.

                                                         TO EMPLOYMENT AGREEMENT

                          DISPUTE RESOLUTION PROCEDURE

            1. Scope of Arbitration. The parties to the Employment Agreement
will submit to final and binding arbitration as the sole and exclusive remedy
for all claims for damages arising out of, involving, or relating to (a) the
Employment Agreement or any amendment thereto or (b) the events giving rise to
the Employment Agreement, including any and all non-contractual claims for
damages related to the Employment Agreement or the events giving rise to it
(including claims for fraudulent inducement of contract). Notwithstanding the
foregoing, the dispute resolution procedure set forth in this Exhibit B does not
apply to claims for injunctive or other equitable relief pursuant to the express
terms of the Employment Agreement or any other agreement entered into in
connection with the Employment Agreement.

            2. Notice of Dispute. Any party shall give the other parties written
notice of the existence and nature of any dispute proposed to be arbitrated
pursuant to this Exhibit B (the "Written Notice"). Such Written Notice must be
served on the other parties as described below. The party serving Written Notice
shall be referred to as the "Claiming Party." The party to whom the claims are
directed shall be referred to as the "Responding Party."

            3. Appointment of Arbitrators. Each party shall appoint one person
to serve as an arbitrator within seven days of receipt of the Written Notice.
The two arbitrators thus appointed shall within seven days of their appointment
together select a third arbitrator with such knowledge and expertise as
necessary to serve as chairman of the panel of arbitrators, and this person
shall serve as chairman. The three arbitrators shall determine all matters,
including the panel's final decision with respect to the claims presented in the
arbitration, by majority vote. If the two arbitrators selected by the parties
are unable to agree upon the appointment of the third arbitrator within seven
days of their appointment, both shall give written notice of such failure to
agree to the parties, and if the parties fail to agree upon the selection of
such third arbitrator within five days thereafter, such third arbitrator shall
be appointed from, and pursuant to the rules for commercial arbitration of, the
American Arbitration Association. Prior to appointment, each arbitrator shall
agree to conduct such arbitration in strict accordance with the terms of this
Exhibit B.

            4. Initial Meeting of the Arbitrators. Within seven days of the
selection of the third arbitrator, the arbitrators shall conduct an initial
meeting with the parties (the "Initial Meeting"). All meetings between the
arbitrators, or between the arbitrators and the parties, including the Initial
Meeting, may be conducted by telephone, with the exception of the arbitration
hearing at which evidence is presented. At the Initial Meeting, the parties and
the arbitrators shall agree upon a schedule for the arbitration proceedings,
with dates no later than the deadlines provided in Section 7 below. The
   18

statement of claim, the response to the statement of claim and counterclaims (if
any), and the response to the counterclaims (if any) (collectively, the
"Pleadings") shall be submitted to each arbitrator on the date they are served,
unless service occurs prior to appointment of all three arbitrators. If service
of any of the Pleadings occurs prior to the appointment of any of the
arbitrators, copies of any such Pleadings shall be submitted to such arbitrator
promptly after such arbitrator's appointment.

            5. Conduct of the Arbitration. No more than eleven months shall pass
between the selection of the third arbitrator and the release of a decision by
the arbitration panel. Any arbitration held pursuant to this Exhibit B shall
take place in New York City, New York. The law of the State of New York shall
supply the substantive law of the arbitration proceedings, and any claims or
counterclaims alleged pursuant to federal law shall be adjudicated as if pled in
a federal court in New York. All proceedings, including discovery, depositions,
and the arbitration hearings shall be governed by the Federal Rules of Civil
Procedure and the Civil Rules of the United States District Court for the
Southern District of New York, unless such rules conflict with the provisions of
this Exhibit B, in which case the provisions of this Exhibit B control.

            6. Motions. The parties may make applications to the panel of
arbitrators regarding issues of discovery, procedure and privilege. Any such
motions shall be made to and resolved by the arbitrators as soon as practicable.
No party shall be permitted to file any motions for dismissal of claims
(including dismissal based upon failure to join an indispensable party), or for
summary judgment, concerning the claims or counterclaims asserted in any
arbitration under this Exhibit B.

            7. Schedule of Arbitration Proceedings. At the Initial Meeting, the
parties and the arbitrators shall agree to a schedule that conforms with the
following deadlines:

                                  provided to the parties and the arbitrators.  


            8. Decision Binding on the Parties. Unless the parties agree
otherwise in writing, the arbitrators' decision shall become binding on the
parties at such time as the decision is confirmed by order of the Supreme Court
of the State of New York, County of New York. The parties hereby irrevocably and
unconditionally submit to the jurisdiction of such court for any and all
proceedings relating to such confirmation. Any award ordered shall be paid

costs incurred by the parties in conjunction with an arbitration proceeding
pursuant to this Exhibit B, including attorney's fees, fees paid to experts, and
fees for obtaining transcripts shall be paid or reimbursed in accordance with
the provisions of Article V of the Employment Agreement. In the event that the
arbitrators determine that no party is entitled to indemnification by any other
party, then (a) each party shall pay its own expenses, including attorney's
fees, fees paid to experts, fees for obtaining transcripts, expenses of
witnesses called solely by that party, and all fees charged by the arbitrator
appointed by such party and (b) the parties shall each pay fifty percent of all
remaining expenses of the arbitration proceeding.
