                                                                       C&B DRAFT
                                                                         5-13-02

      AGREEMENT, dated as of May 13, 2002, among the stockholders (the
      "Stockholders) of Heafner Tire Group, Inc., a Delaware corporation
      (the "Company") named on the signature pages hereto
      ------------------------------------------------------------------


                                   Background
                                   ----------

         The Stockholders desire to enter into this Agreement in order to
facilitate the orderly operation of the Company, improve the Company's financial
position and business prospects and enhance the value of the shares of the
Company's capital stock currently held by them. In furtherance of the foregoing,
the Stockholders desire to modify the terms of the Series C and Series D
Preferred Stock of the Company so that such Preferred Stock will be redeemable
at the option of the Company and not of the holders thereof.

         In consideration of the premises and mutual agreements contained
herein, and for other good and valuable consideration, the Stockholders agree as
follows:

                                    Agreement
                                    ---------

         1. The Stockholders agree to convene such special meetings, execute
such written consents and take such other stockholder actions as may be
necessary to amend and/or restate the Company's certificate of incorporation to
eliminate the rights of holders of shares of Series C Preferred Stock and Series
D Preferred Stock of the Company to (i) require the Company to redeem such
shares pursuant to Sections 6A.4(a) and 6B.4(a) thereof and (ii) elect to
receive accumulated but unpaid dividends on such shares in the form of cash
rather than shares of Common Stock upon conversion thereof pursuant to Sections
6A.2(c) and 6B.2(c) of the Company's certificate of incorporation.

         2. This Agreement (i) may be amended, terminated, waived or revoked
only by a written instrument signed by all of the parties hereto, (ii) may be
executed in one or more counterparts, each of which shall be deemed to be an
original and all of which taken together shall constitute one Agreement and
(iii) shall be governed by and construed in accordance with the laws of the
State of Delaware.

         IN WITNESS WHEREOF, the Stockholders have duly executed and delivered
this Agreement as of the date first written above.
