HEAFNER COMPANY, INC., a North Carolina corporation (the "Company"), and _______________________ (the "Purchaser"). Introduction The Purchaser is, upon the date hereof, exercising his option to purchase _________ shares (the "Shares") of the Company's common stock, par value $.01 per share (the "Common Stock"), at a price of $__________ per Share (the "Purchase Price"), pursuant to the Company's 1997 Stock Option Plan (the " Option Plan"). On or about May 7, 1997, (i) the Company entered into the Loan and Security Agreement with BankBoston, N.A., pursuant to which up to $65.0 million in indebtedness (the "Senior Financing") was made available to the Company and Oliver & Winston, Inc. ("Winston"), (ii) the Company issued senior subordinated notes in the principal amount of $16.0 million pursuant to a Senior Subordinated Note and Warrant Purchase Agreement with The 1818 Mezzanine Fund, L.P. (the "Senior Subordinated Financing"), (iii) the Company issued warrants (the "Warrants") in connection with the Senior Subordinated Financing and, (iv) the Company issued shares of Series A Cumulative Redeemable Preferred Stock and shares of Series B Cumulative Redeemable Preferred Stock (collectively, the "Preferred Stock") to The Kelly-Springfield Tire Company. Subsequent to such date, certain members of management of the Company and Winston (the "Management Stockholders") entered into a Securities Purchase and Stockholders' Agreement dated as of May 28, 1997 (the "Stockholders' Agreement"), pursuant to which the Management Stockholders agreed to purchase shares of Common Stock and agreed to certain restrictions on the transferability of their shares of Common Stock. All of such transactions are referred to herein as the "Overall Transaction." As a condition to the Purchaser's exercise of his option to acquire the Shares, the Purchaser is entering into this agreement. For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows: -1- 2 ARTICLE I Transferability of Shares SECTION 1.1. Stock Transfer Restrictions. The Purchaser shall not sell, assign, pledge, give away or otherwise transfer (a "Transfer") any Shares except in accordance with the procedures set forth in this Agreement. Any attempted Transfer of Shares not permitted by this Agreement shall be null and void, and the Company shall not in any way give effect to any such Transfer. Any proposed Transfer of Shares shall be null and void, and the Company shall not in any way give effect to any such Transfer, unless the transferee of such Shares who is not, immediately prior to such Transfer, a Management Stockholder shall agree in writing to be bound by and comply with the provisions of this Agreement SECTION 1.2. Termination of Employment. (a) Transfers upon Termination for Cause. If the Company shall terminate the Purchaser's employment for "Cause" or the Purchaser shall terminate his employment with the Company other than for "Good Reason" (as such terms are defined below), the Company shall have the right, commencing on the date of such termination and continuing until the first anniversary thereof, to purchase all or part of such Purchaser's Shares at the Repurchase Price applicable thereto, provided that if and to the extent that, prior to such first anniversary, the Company is prohibited under the terms of any loan agreement or note for borrowed money from making such repurchase to the full extent it would otherwise do so, the Company shall have the right to purchase such Shares until the expiration of 45 days after such first anniversary. For purposes of this Section 1.2, "Company" shall include Winston with respect to a Purchaser employed directly by Winston. For purposes of this Agreement, "Cause", with respect to the Purchaser, has the meaning set forth in the employment agreement, if any, then in effect between the Company and the Purchaser or, in the absence of such an agreement, shall mean (i) the Purchaser's conviction of, or plea of guilty or nolo contendere to a felony, (ii) the Purchaser's gross negligence in the performance of his employment services to the Company, which is not corrected within 15 business days after written notice, (iii) the Purchaser's knowingly dishonest act, or knowing bad faith or willful misconduct in the performance of such services to the material detriment of the Company, which is not corrected within 15 business days after written notice, or (iv) the Purchaser's other material breach of his obligations as an employee or officer of the Company which is not corrected within a reasonable period of time (determined in light of the cure appropriate to such material breach, but in no event less than 15 business days) after written notice. "Good Reason", with respect to the Purchaser, has the meaning set forth in the employment agreement, if any, then in effect between the Company and the Purchaser or, in the absence of such an agreement, shall mean (i) the failure of the Company to pay any undisputed amount due to the Purchaser in connection with his employment by the Company or a substantial diminution in benefits provided pursuant to such employment, (ii) a substantial diminution in the 2 3 status, position and responsibilities of the Purchaser that is not instituted to all senior management of the Company or (iii) the Company requiring the Employee to be based at any office or location that requires a relocation or commute greater than 50 miles from the office or location to which the Purchaser is currently assigned. "Repurchase Price" means, with respect to each Share, the greater of (i) the Purchase Price applicable thereto and (ii) the quotient obtained by dividing the Net Equity Value by the total number of shares of Common Stock outstanding on the date of termination of the Purchaser's employment (on a fully diluted basis, after assuming the issuance of shares of Common Stock pursuant to the exercise of in-the-money options granted under the Option Plan and in-the-money Warrants). "Net Equity Value" means the sum of (x) 6 times the Company's EBITDA (as calculated in accordance with the Loan and Security Agreement dated May 7, 1997 among the Company, Winston, the financial institutions identified therein and BankBoston, N.A., as agent) for the 12 full calendar months immediately preceding the date on which such termination shall have occurred, plus (y) the aggregate exercise price of all options granted under the Option Plan and all Warrants, which exercise price at the date such termination shall have occurred does not exceed (on a per share basis) the per share market value of the Common Stock, less (z) the aggregate amount of principal of and interest on (in the case of debt) and liquidation value of (in the case of capital stock) the Senior Financing, Senior Subordinated Financing and Preferred Stock outstanding as of the date of such termination. (b) Termination other than for Cause. If the Company shall terminate the Purchaser's employment other than for Cause or the Purchaser shall terminate his employment with the Company for Good Reason, the Purchaser shall have the right, commencing on the date of such termination and continuing until the first anniversary thereof, to require the Company to purchase all or part of the Purchaser's Shares at the Repurchase Price applicable thereto; provided that if and to the extent that, prior to such first anniversary, the Company is prohibited under the terms of any loan agreement or note for borrowed money from purchasing such Shares to the extent so required by the Purchaser borrowed money from purchasing such Shares to the extent so required by the Purchaser, the Company shall not be obligated to make such purchase until it is no longer prohibited from doing so, in which case payment shall be made promptly after the removal of such prohibition. In the event the option is not exercised, the Company shall have the right, commencing on the first anniversary and continuing until the second anniversary thereof, to purchase all of the Purchaser's Shares at the Repurchase Price applicable thereto. (c) Termination or Repurchase upon Death. If the Purchaser's employment with the Company shall terminate due to the Purchaser's death, or, following any other termination of employment by the Company, the Purchaser shall die, the Company shall have the right to purchase, and the Purchaser's descendants shall have the right to require the Company to purchase, all or part of the Purchaser's Shares at the Repurchase Price applicable thereto, commencing on the date of death of the Purchaser and continuing until the first anniversary thereof; provided that if and to the extent that, prior to such anniversary, the Company is prohibited under the terms of any loan agreement or note for borrowed money from purchasing such Shares to the extent so required by the Purchaser's descendants, the Company shall not be 3 4 obligated to make such purchase until it is no longer prohibited from doing so, in which case payment shall be made promptly after the removal of such prohibition. (d) Delivery of Payment. The Company or the Purchaser, as the case may be, shall notify the other of such party's exercise of its rights under this Section 1.2 by giving written notice of such exercise at least 10 and not more than 30 days before the date established by such electing party for such purchase or sell, as the case may be.

If any Shares evidenced by a certificate so surrendered are not being purchased pursuant to the terms hereof, the Company shall promptly issue to the Purchaser a replacement certificate evidencing the Shares not so purchased. SECTION 1.3. Transfers Among Management or to Descendants. (a) The Purchaser may, so long as any right has not been exercised with respect to such Shares pursuant to Section 1.2, Transfer any Shares to a Management Stockholder or other management employee of the Company or Winston who has or does acquire shares of Common Stock pursuant to a purchase agreement substantially in the form of the agreement entered into with the Management Stockholders or pursuant to an exercise of any option under the Option Plan (a "Management Employee"). The Purchaser may Transfer by will or the laws of descent and distribution any Shares to the Purchaser's descendants. Such transfer shall be effective only if the transferee agrees to be bound by the terms of this Agreement. SECTION 1.4. Right of First Refusal. With respect to any Shares that the Company had the right to purchase pursuant to Section 1.2(a) or Section 1.2(c) but failed to so purchase prior to the expiration of the one-year period referred to therein (as the same may be extended due to the Company's inability to purchase such Shares as described therein), the following provisions shall apply. (a) If the Purchaser desires to Transfer any such Shares (other than pursuant to Section 1.3), the Purchaser shall deliver to the Company and the Management Stockholders and Management Employees a written notice, which shall be irrevocable for a period of 45 days after delivery, offering all of such Shares to the Company and the Management Stockholders and Management Employees at the purchase price and on the terms specified in the written notice. The Company shall have the first right and option, for a period of 30 days after delivery of such written notice, to purchase all (but not part) of such Shares at the purchase price and on the terms specified in the notice. Such acceptance shall be made by delivering a written notice to the Purchaser within such 30-day period. (b) If the Company fails to accept such offer, then upon the earlier of the expiration of such 30-day period or upon the receipt of a written rejection of such offer from the Company, the Management Stockholders and Management Employees (as a group) shall have the second right and option, until 15 days after the expiration of the 30-day period, to purchase 4 5 on a pro rata basis with all Management Stockholders and Management Employees so electing all (but not part) of such Shares offered at the purchase price and on the terms specified in the notice. Such acceptance shall be made by delivering a written notice to the Purchaser within the 15-day period. (c) If the Company and the Management Stockholders and Management Employees do not elect to purchase the Shares so offered, then the Purchaser may Transfer all (but not part) of such Shares at a price not less than the price, and on terms not more favorable to the transferee of such Shares than the terms, stated in the original written notice of intention to sell, at any time within 15 days after the expiration of the period in which the Management Stockholders and Management Employees could elect to purchase such Shares. If such Shares are not sold by the Purchaser during such 15-day period, the right of the Purchaser to sell such Shares shall expire and the rights and obligations set forth in this Section 1.4 shall be reinstated with respect to such Shares. SECTION 1.5. Lock-up Agreements.
