numerator of which is the aggregate EBITDA of the Company for all fiscal years
following the date hereof, beginning with the 1999 fiscal year, multiplied by

shall vest and become exercisable immediately upon the vesting and
exercisability of the remaining 50% of the Tier 3 Options, and (2) the seventh
anniversary of the date hereof.

Control that satisfies the CIC Return Hurdle and (y) an Actual Sale or Deemed
Sale following a Qualified Public Offering that satisfies the QPO Return Hurdle
as hereinafter described. If on any date beginning six months after a Qualified
Public Offering the QPO Return Hurdle has been satisfied based on a Deemed Sale

                  (ii) Options exercised in any one year shall be deducted from

shall be exercisable at the following times prior to the expiration date: (A) if
the Optionee is employed by the Company at the time of exercise, at any time by
giving the Company 45 days' advance written notice or (B) if the Optionee is not
employed by the Company at the time of exercise but has the right to exercise
after termination in accordance with Section 2(d) of this Agreement, by giving
the Company written notice at any time during the period specified in Section
2(d) of this Agreement, in which case the Option shall be deemed exercised as of
the end of the calendar month in which the Company received notice of exercise
of the Option. In either case, the notice of exercise shall specify the number
of Shares as to which the Option is being exercised.

                  (iii) Upon receipt of written notice of exercise by the
Company, the Company shall, upon full payment in cash to the Company of the
Exercise Price of the Shares as to which the Option shall be exercised and upon
receipt of a duly executed shareholders agreement (in the form attached hereto
as Exhibit A or in such other form as the Company may reasonably require), issue

Optionee pursuant to the preceding sentence shall be made by the Company within
90 days after the date of exercise. For purposes of this Agreement, the fair
market value of Shares shall be determined by such methods or procedures as
shall be established from time to time by the Board acting in its sole
discretion and in good faith. In making such determinations, the Board may rely
on a valuation report by an investment banking or valuation firm selected by the
Board. The Committee established by the Board to administer the Plan (the
"Committee") may, in its sole discretion, permit the Optionee to pay the
Exercise Price in previously acquired Shares rather than in cash.

                  (d) Exercise Upon Death or Termination of Employment.

                           (i) If the Optionee dies while an employee of the
Company, the Optionee's Designee may exercise the Option, to the extent it was
vested on the date of termination, by giving the Company written notice of such
exercise within 12 months after the date of Optionee's death, but in no event
later than the Expiration Date. An Optionee's "Designee" means the person
designated by the Optionee in his or her most recently filed beneficiary
designation filed with the Company to receive the Optionee's rights under the
Plan upon the

                                       6
<PAGE>   7

Optionee's death, or if there is no such designation or no such designated
person survives the Optionee, by the person or persons to whom the Optionee's
rights pass by will or applicable law, or if no such person has such right, by
his executors or administrators.

                           (ii) If the Company shall terminate Optionee's
employment with the Company because of disability, the Optionee may exercise the
Option to the extent it was vested on the date of termination, by giving the
Company written notice of such exercise within 12 months after the date of
termination of employment, but in no event later than the Expiration Date.

                           (iii) If the Optionee terminates his employment with
the Company other than for Good Reason, the Optionee may exercise the Option to
the extent it was vested on the date of termination, by giving the Company
written notice of such exercise within 90 days after the date of termination of
employment, but in no event later then the Expiration Date. For purposes of this
Agreement, "Good Reason" has the meaning set forth in the executive severance or
employment agreement, if any, then in effect between the Company and the
Optionee or, in the absence of such agreement shall mean, if the basis for such
Good Reason is not cured within a reasonable period of time (determined in light
of the cure appropriate to the basis of such Good Reason, but in no event less
than 15 days), the failure of the Company to pay any undisputed amount due to
the Optionee in connection with his employment by the Company.

                           (iv) If the Optionee's employment shall terminate for
any reason other than death, disability or Cause (as hereinafter defined), or if
the Optionee shall terminate his employment with the Company for Good Reason,
the Optionee may exercise the Option to the extent it was vested on the date of
termination or, otherwise would have vested in the 12 months thereafter, in
either event according to the applicable vesting schedule in Section 2(c)(i), by
giving the Company written notice of such exercise within 18 months after the
date of termination of employment, but in no event later than the Expiration
Date. Notwithstanding the foregoing, the Optionee shall forfeit his right to
exercise any Options that would have vested within the 12 months after
termination, if the Optionee violates the terms regarding non-competition set
forth in the Optionee's executive severance or employment agreement.

                           (v) If the Optionee's employment shall terminate for
Cause, all right to exercise the Option shall terminate at the date of such
termination of employment. For purposes of this Agreement, "Cause" has the
meaning set forth in the executive severance or employment agreement, if any,
then in effect between the Company and the Optionee or, in the absence of such
agreement, shall mean (i) the Optionee's conviction of, or plea of guilty or
nolo contendere to, a felony, (ii) the Optionee's gross negligence in the
performance of his duties and obligations to the Company, which is not corrected
within 15 business days after written notice, (iii) the Optionee's knowingly
dishonest act, or knowing bad faith or willful misconduct in the performance of
his duties and obligations to the Company to the material detriment of the
Company, which is not corrected within 15 business days after written notice, or
(iv) the Optionee's other material breach of his obligations under this
Agreement, which is not corrected

                                       7
<PAGE>   8

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.

                           (vi) In the event of termination of employment, if an
Incentive Stock Option is exercised after the expiration of the exercise periods
that apply for purpose of Section 422 of the Code, such stock option shall
thereafter be treated as a nonqualified stock option.

                  (e) Transferability. Except as otherwise provided in this
Section, the Option is not transferable other than as designated by the Optionee
in his or her most recently filed Beneficiary designation filed with the
Company, or if there is no such designation or no such designated person
survives the Optionee, as designated by the Optionee, by will or by the laws of
descent and distribution, and during the Optionee's life, may be exercised only
by the Optionee. However, an Optionee, with the approval of the Committee, may
transfer the Option for no consideration to or for the benefit of the Optionee's
Immediate Family or to a partnership or limited liability company for one or
more members of the Optionee's Immediate Family, subject to such limits as the
Committee may establish, and the transferee shall remain subject to all the
terms and conditions applicable to Options prior to such transfer. The foregoing
right to transfer the Option shall apply to the right to consent to amendments
to this Agreement and, in the discretion of the Committee, shall also apply to
the right to transfer ancillary rights associated with the Option. The term
"Immediate Family" shall mean the Optionee's spouse, parents, children,
stepchildren, adoptive relationships, sisters, brothers, nieces, nephews and
grandchildren (and, for this purpose, shall also include the Optionee).

                  (f) Adjustments. In the event of any change in corporate
capitalization (including, but not limited to, a change in the number of shares
of Common Stock outstanding), such as a stock split or a corporate transaction,
such as any merger, consolidation, separation, including a spin-off, or other
distribution of stock or property of the Company, any reorganization (whether or
not such reorganization comes within the definition of such term in Section 368
of the Code) or any partial or complete liquidation of the Company, the
Committee or Board may make such substitution or adjustments in the number, kind
and option price of shares subject to the Option and/or such other equitable
substitution or adjustments as it may determine to be appropriate in its sole
discretion; provided, however, that the number of shares subject to the Option
shall always be a whole number. In the event of a corporate merger,
consolidation, acquisition of property or stock, separation, reorganization or
liquidation, the Board shall be authorized to cause the Company to issue or
assume stock options, whether or not in transaction to which Section 424(a) of
the Code applies, by means of substitution of new stock options for previously
issued stock options or an assumption of previously issued stock options.

                  (g) No Rights as Stockholder. The Optionee shall have no
rights as a stockholder with respect to any Shares subject to the Option prior
to the date of issuance to the Optionee of a certificate or certificates for
such Shares.

                  (h) Optionee Acknowledgement. The Optionee acknowledges that:

                                       8

                           (i) the future value of the Company is highly
speculative;

                           (ii) the Optionee is not relying on the value of this
Option as current compensation;

                           (iii) the Company has no obligation to the Optionee
to sell the Company or to sell Shares publicly (which may have the effect of
reducing the value of the Company);

                           (iv) upon exercise of this Option, unless the Shares
issuable upon exercise of the Options have been registered under applicable
securities laws, there will be substantial restrictions on the transferability
of the Shares; and

                           (v) the past performance or experience of the
Company, the Company's officers, directors, agents, or employees, will not in
any way indicate or predict the results of the ownership of Shares or of the
Company's activities.

                  (i) No Right to Continued Employment. The Option shall not
confer upon the Optionee any right with respect to continuance of employment by
the Company, nor shall it interfere in any way with the right of the Optionee's
employer to terminate the Optionee's employment at any time.

                  (j) Compliance With Law and Regulations. The Option herein
granted and the obligation of the Company to sell and deliver shares hereunder,
shall be subject to all applicable Federal and State laws, rules and regulations
and to such approvals by any government or regulatory agency as may be required.
The Company shall not be required to issue or deliver any certificates for
Shares prior to (i) the listing of such Shares on any stock exchange or national
market quotations system on which the Shares may then be listed and (ii) the
completion of any registration or qualification of such Shares under any Federal
or State law, or any rule or regulation of any government body which the Company
shall, in its sole discretion, determine to be necessary or advisable. Moreover,
the Option herein granted may not be exercised if its exercise, or the receipt
of Shares pursuant hereto, would be contrary to applicable law.

                            HEAFNER TIRE GROUP, INC.
                             STOCK OPTION AGREEMENT

Number of shares subject to option: 10,000

         This Agreement (the "Agreement") made this 10th day of December, 1999,
between Heafner Tire Group, Inc., a Delaware corporation (the "Company"), and
Ray C. Barney (the "Optionee").

                              W I T N E S S E T H:

1.       Grant of Option.

         Pursuant to the provisions of the Heafner Tire Group, Inc. 1999 Stock
Option Plan (the "Plan"), the Company hereby grants to the Optionee, subject to
the terms and conditions of the Plan and subject further to the terms and
conditions herein set forth, the right and option (the "Option") to purchase
from the Company all or any part of an aggregate of 10,000 shares of the common
stock, par value $0.01 per share, of the Company (the "Common Stock" or the
"Shares") at a purchase price of $9.00 per Share (the "Exercise Price"), such
Option to be exercised as hereinafter provided.

2.       Terms and Conditions.

         It is understood and agreed that the Option evidenced hereby is subject
to the following terms and conditions:

                  (a) Expiration Date. The Option shall expire on the tenth
anniversary of the date hereof (the "Expiration Date").

                  (b) Type of Option. This option is eligible to be an incentive
stock option within the meaning of Section 422 of the Internal Revenue Code of
1986, as amended (the "Code").

                  (c) Exercise of Option. (i) Subject to the other terms of this
Agreement regarding the exercisability of this Option, this Option may be
exercised in accordance with the following vesting schedule:

                                         Options Exercisable with respect to
         On or After                     Cumulative Number of Shares
         -----------                     -----------------------------------
         November 25, 2000               10,000 x 25%
         November 25, 2001               10,000 x 25%
         November 25, 2002               10,000 x 25%
         November 25, 2003               10,000 x 25%

<PAGE>   2

Options exercised in any one year shall be deducted from the number of Options
exercisable in any future year. Once vested, this Option shall be exercisable at
the following times prior to the expiration date: (A) if the Optionee is
employed by the Company at the time of exercise, at any time by giving the
Company 45 days' advance written notice or (B) if the Optionee is not employed
by the Company at the time of exercise but has the right to exercise after
termination in accordance with paragraph 2(d) of this Agreement, by giving the
Company written notice at any time during the period specified in paragraph 2(d)
of this Agreement, in which case the Option shall be deemed exercised as of the
end of the calendar month in which the Company received notice of exercise of
the Option. In either case, the notice of exercise shall specify the number of
Shares as to which the Option is being exercised.

                           (ii) Upon receipt of written notice of exercise by
the Company, the Company shall, upon full payment in cash to the Company of the
Exercise Price of the Shares as to which the Option shall be exercised, issue to
the Optionee the Shares subject to the Option. Any issuance of Shares to an
Optionee pursuant to the preceding sentence shall be made by the Company within
90 days after the date of exercise. For purposes of this Agreement, the fair
market value of Shares shall be determined by such methods or procedures as
shall be established from time to time by the Board of Directors of the Company
(the "Board") acting in its sole discretion and in good faith. In making such
determinations, the Board may rely on a valuation report by an investment
banking or valuation firm selected by the Board. The Committee established by
the Board to administer the Plan (the "Committee") may, in its sole discretion,
permit the Optionee to pay the Exercise Price in previously acquired Shares
rather than in cash.

                  (d) Exercise Upon Death or Termination of Employment.

                           (i) If the Optionee dies while an employee of the
Company, the Optionee's Designee may exercise the Option, to the extent it was
vested on the date of termination or otherwise would have vested in the 12
months thereafter in accordance with the vesting schedule in Section 2(c)
hereof, by giving the Company written notice of such exercise within 180 days
after the date of Optionee's death, but in no event later than the Expiration
Date. An Optionee's "Designee" means the person designated by the Optionee in
his or her most recently filed beneficiary designation filed with the Company to
receive the Optionee's rights under the Plan upon the Optionee's death, or if
there is no such designation or no such designated person survives the Optionee,
by the person or persons to whom the Optionee's rights pass by will or
applicable law, or if no such person has such right, by his executors or
administrators.

                           (ii) If the Optionee's employment with the Company
shall terminate because of permanent disability, the Optionee may exercise the
Option to the extent it was vested on the date of termination or otherwise would
have vested in the 12 months thereafter, in either event according to the
vesting schedule in Section 2(c), by giving the Company written notice of such
exercise within 180 days after the date of termination of employment, but in no
event later than the Expiration Date.

                           (iii) If the Optionee's employment shall terminate
for any reason other than death or permanent disability as aforesaid or for
Cause (as hereinafter defined), the Optionee may exercise the Option to the
extent it was vested on the date of termination or otherwise would have vested
in the 12 months thereafter, in either event according to the vesting schedule
in Section 2(c),

                                       2
<PAGE>   3

by giving the Company written notice of such exercise within 180 days after the
date of termination of employment, but in no event later than the Expiration
Date.

                           (iv) If the Optionee's employment shall terminate for
Cause, all right to exercise the Option shall terminate at the date of such
termination of employment except that the Optionee may exercise the Option to
the extent vested as of the date of such termination by giving the Company
written notice thereof within 30 days after such termination. For purposes of
this Agreement, "Cause" shall mean (i) the Employee's conviction of, or plea of
guilty or nolo contendere to, a felony, (ii) the Employee's gross negligence in
the performance of his duties and obligations to the Company, which is not
corrected within 15 business days after written notice, (iii) the Employee's
knowingly dishonest act, or knowing bad faith or willful misconduct in the
performance of his duties and obligations to the Company to the material
detriment of the Company, which is not corrected within 15 business days after
written notice, or (iv) the Employee's other material breach of his obligations
under this Agreement, 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.

                  (e) Nontransferability. This Option shall not be transferable
other than by will or by the laws of descent and distribution. During the
lifetime of the Optionee, this Option shall be exercisable only by such
Optionee.

                  (f) Forfeiture of Option Gain. If at any time within 12 months
after the later of (i) termination of employment or (ii) the date on which the
Optionee exercises any portion of this Option, the Optionee violates the terms
of the covenants regarding confidential information, soliciting customer
accounts, non-competition or hiring of employees, currently set forth in
Sections 2 and 3 of the Employment Agreement between the Company and the
Optionee dated the date hereof (the "Employment Agreement"), (A) then any income
realized by the Optionee upon the exercise of this Option or upon the sale of
Shares acquired by exercise of this Option at any time, whether before or after
the date of termination of employment, shall promptly be paid by the Optionee to
the Company and (B) any unexercised Options shall be canceled. The Company shall
have the right to set off against any amount payable by the Company to the
Optionee, including, without limitation, salary, benefits or other amounts, any
amounts owed by the Optionee to the Company under this subparagraph (f). The
Committee may waive the requirements of this subparagraph (f) if it determines
in its sole discretion that such action is in the best interests of the Company.

                  (g) Adjustments. In the event that the Committee shall
determine, in its sole discretion, that any dividend or other distribution
(whether in the form of cash, Common Stock, or other property),
recapitalization, stock split, reverse split, any reorganization, merger,
consolidation, spin-off, combination, repurchase, share exchange, license
arrangement, strategic alliance or other corporate transaction or event, affects
the Shares such that an adjustment is appropriate in order to prevent dilution
or enlargement of the rights of the Optionee under the Plan, then the Committee
shall make such equitable changes or adjustments as it deems necessary or
appropriate to any or all of (i) the number and kind of Shares which may
thereafter be issued in connection with Options, (ii) the number and kind of
Shares issued or issuable in respect of outstanding Options, and (iii) the
Exercise Price relating to any Option; provided that, with respect

                                       3
<PAGE>   4

to incentive stock options, such adjustment shall be made in accordance with
Section 424(h) of the Code.

                  (h) No Rights as Stockholder. The Optionee shall have no
rights as a stockholder with respect to any Shares subject to the Option prior
to the date of issuance to the Optionee of a certificate or certificates for
such Shares.

                  (i) Optionee Acknowledgement. The Optionee acknowledges that:

                           (i) the future value of the Company is highly
speculative;

                           (ii) the Optionee is not relying on the value of this
Option as current compensation;

                           (iii) the Company has no obligation to the Optionee
to sell the Company or to sell Shares publicly (which may have the effect of
reducing the value of the Company);

                           (iv) upon exercise of this Option, unless the Shares
issuable upon exercise of the Options have been registered under applicable
securities laws, there will be substantial restrictions on the transferability
of the Shares; and

                           (v) the past performance or experience of the
Company, the Company's officers, directors, agents, or employees, will not in
any way indicate or predict the results of the ownership of Shares or of the
Company's activities.

                  (j) No Right to Continued Employment. The Option shall not
confer upon the Optionee any right with respect to continuance of employment by
the Company, nor shall it interfere in any way with the right of the Optionee's
employer to terminate the Optionee's employment at any time.

                  (k) Compliance With Law and Regulations. The Option herein
granted and the obligation of the Company to sell and deliver shares hereunder,
shall be subject to all applicable Federal and State laws, rules and regulations
and to such approvals by any government or regulatory agency as may be required.
The Company shall not be required to issue or deliver any certificates for
Shares prior to (i) the listing of such Shares on any stock exchange or national
market quotations system on which the Shares may then be listed and (ii) the
completion of any registration or qualification of such Shares under any Federal
or State law, or any rule or regulation of any government body which the Company
shall, in its sole discretion, determine to be necessary or advisable. Moreover,
the Option herein granted may not be exercised if its exercise, or the receipt
of Shares pursuant hereto, would be contrary to applicable law.

                  (l) Condition Precedent. In consideration for and as a
condition precedent to being eligible to participate in the Plan, the Optionee
shall have executed and delivered to the Company the Employment Agreement.
