ability to make public or private announcements, statements or other
communications as required to comply with applicable law or the rules of any

                  SECTION 2.01. Consulting Services. (a) Employer shall retain
Executive, and Executive shall serve, as a consultant to Employer during the
period from the Effective Date through the second anniversary of the Effective
Date (the "Consulting Term"). During the portion of the Consulting Term ending
on the first anniversary of the Effective Date (the "Initial Period"), Executive
shall provide an average of no more than 20 hours of consulting services per
week, and Executive acknowledges and agrees that Employer shall be entitled to
determine the number of hours of services for each week during such period, but
in no event shall Employer request more than 30 hours of services for any such
week. During the remaining portion of the Consulting Term (the "Remaining
Period"), Executive shall provide such hours of consulting services as may be
requested by Employer in its discretion, but in no event shall Employer request
more than 20 hours of services for any week during such period. During the
Consulting Term, Executive shall assist and advise Employer and its employees
with respect to matters in which Executive was involved or had knowledge from
his services as an employee of Employer, including by facilitating Employer's
efforts to train Executive's successor as Chief Financial Officer. In rendering
such consulting services, Executive shall report to the Chief Executive Officer
of Employer (the "CEO") or to such other person as may be designated from time
to time by the CEO. Executive shall perform his services hereunder (i) primarily
at the corporate headquarters of Employer in Bristol, Tennessee and at

Employer's request, at locations related to litigation or other legal matters
involving or affecting Employer or its affiliates and (iii) at such other
locations as may be mutually agreed from time to time by Employer and Executive.
Executive acknowledges that his duties and responsibilities hereunder will
require him to travel on business from time to time, and for such purposes
Employer shall make its corporate aircraft reasonably available to Executive.
Any time spent by Executive in connection with such travel shall be credited
against the consulting services Executive is required to provide pursuant to
this Article II. Executive may perform his consulting services hereunder by
telephone or email in appropriate circumstances reasonably acceptable to
Employer. Executive shall serve

                                       3

<PAGE>

Employer in good faith and to the best of Executive's abilities in connection
with the performance of his consulting services hereunder.

            (b) Notwithstanding anything in this Article II to the contrary, in
the event that Executive accepts or commences active, full-time employment with
any person or entity that is a direct competitor with Employer or its affiliates
(as determined by Employer in its reasonable discretion) during the Consulting
Term, Employer may, in its reasonable discretion, elect to (i) continue the
consulting arrangements described in this Article II on the terms and conditions
set forth herein or (ii) terminate such arrangements (other than Employer's
obligation under Section 2.02 to pay the retainer during the Initial Period)
effective as of a date specified by Employer. Following the effective date of
any such termination, (i) Executive shall have no obligation under this Article
II to provide consulting services to Employer and (ii) Employer shall have no
obligation under this Article II to pay any amount to Executive (other than any
retainer earned but unpaid under Section 2.02 and any business expense incurred
but not reimbursed under Section 2.03, in each case as of the effective date of
such termination); provided, however, that such termination shall have no effect
on (A) Employer's obligation under Section 2.02 to pay the retainer during the
Initial Period or (B) any other provision of this Agreement, including
Executive's obligations under Article I.

                  SECTION 2.02. Retainer. In consideration of all consulting
services rendered pursuant to this Article II, without regard to the number of
hours of consulting services requested by Employer, Employer shall pay Executive
a cash retainer at a monthly rate of (i) during the Initial Period, $33,334.00
and (ii) during the Remaining Period, $28,349.33, which in each case shall be
paid in advance on the first business day of the applicable month, commencing on
the Effective Date. Employer's obligation to pay such retainer during the
Initial Period shall not be affected by either (i) Employer's termination of the
consulting arrangements described in this Article II pursuant to Section 2.01(b)
or (ii) Executive's disability or death, in which case such retainer shall be
paid to Executive or to his personal representative.

                  SECTION 2.03. Expense Reimbursement. Employer shall reimburse
Executive for all necessary and reasonable "out-of-pocket" business expenses
incurred by Executive on behalf of Employer in the performance of his consulting
duties under this Article II, subject to the terms and conditions of the
applicable expense reimbursement policy of Employer as in effect from time to
time.

                  SECTION 2.04. Independent Contractor Status. (a) Executive
shall at all times during the Consulting Term be an independent contractor with
respect to Employer, and there shall not be implied any relationship of
employer-employee, partnership, joint venture, principal-agent or any similar
relationship by the provisions of this Agreement. From and after the Effective
Date, Executive shall not be entitled to participate in any employee benefit
plan, program or arrangement or other benefits or conditions of employment
available to the employees of Employer and its affiliates, except as expressly
provided in the Severance Plan (as modified by Section 1.02(b)(ii)).

                                       4

            (b) From and after the Effective Date, Executive shall not have any
authority to act as an agent of Employer or its affiliates, and Executive shall
not represent to the contrary to any person. From and after the Effective Date,
under no circumstances shall Executive have or claim to have power of decision
in any activity on behalf of Employer or its affiliates, nor shall Executive
have the power or authority to obligate, bind or commit Employer or its
affiliates in any respect. From and after the Effective Date, Executive shall
not direct the work of any employee of Employer or its affiliates, make any
management decisions on behalf of Employer or its affiliates or undertake to
commit Employer or its affiliates to any course of action in relation to third
parties. Employer shall not exercise and shall not have the authority to
exercise such level of control over Executive as would indicate or establish
that a relationship of employer-employee exists between Employer and Executive,
except that Employer may specify the results it desires Executive to achieve
during the Consulting Term and may control and direct Executive in that regard.
Subject to the foregoing, Executive shall have full and complete control over
the manner and method of rendering consulting services hereunder.

                                   ARTICLE III

damages, costs and expenses (including reasonable attorneys' fees), liabilities,
judgments and, subject to the proviso of this sentence, settlement amounts that
are paid or incurred in connection with any claim, action, suit, proceeding or
investigation (whether civil, criminal, administrative or investigative and
whether asserted or claimed prior to, at or after the Effective Date) that is
(A) based on, or arises out of, the fact that Executive is or was a director or
officer of Employer or any of its subsidiaries, or (B) based on, or arising out
of, or pertaining to this Agreement or the transactions contemplated hereby, in
each case to the fullest extent a corporation is permitted under applicable law
to indemnify its own directors or officers, as the case may be; provided,
however, that Employer shall not be liable for any settlement of any claim
effected without its written consent (which consent shall not be unreasonably
withheld). Without limiting the foregoing, in the event that any such claim,
action, suit, proceeding or investigation is brought against Executive (whether
arising prior to or after the Effective Date), (w) Employer following the
Effective Date will pay all expenses of the disposition of any such claim,
action, suit, proceeding or investigation to Executive to the full extent
permitted by applicable law promptly after statements therefor are received and
otherwise advance to Executive upon request reimbursement of documented expenses
reasonably incurred, in either case to the extent not prohibited by the
Tennessee Business Corporation Act ("TBCA"); provided, however, that the person
to whom expenses are advanced provides any undertaking required by applicable
law to repay such advance if it is ultimately determined that such person is not
entitled to indemnification; (x) Executive shall retain counsel reasonably
satisfactory to Employer; (y) Employer following the Effective Date shall pay
all reasonable fees and expenses of such counsel for Executive (subject to the
penultimate sentence of this paragraph) and all costs and expenses of Executive

<PAGE>

statements therefor are received and (z) Employer following the Effective Date
shall use all commercially reasonable efforts to assist in the defense of any
such matter. In the event of any dispute as to whether Executive's conduct
complies with the standards set forth under the TBCA and Employer's Charter or
Employer's By-laws, a determination shall be made by independent counsel
mutually acceptable to Employer and Executive; provided, however, that Employer
following the Effective Date shall not be liable for any settlement effected
without its written consent (which consent shall not be unreasonably withheld).
Without limiting the foregoing, to the extent that Executive is, by reason of
the fact that Executive is or was a director or officer of Employer or any of
its subsidiaries, a witness in any claim, action, suit, proceeding or
investigation to which Executive is not a party, Executive shall be indemnified
and held harmless against all costs and expenses in connection therewith.

                  (ii) Employer shall not enter into any settlement of any claim
in which Employer is jointly liable with Executive (or would be if joined in
such claim) unless such settlement provides for a full and final release of all
claims asserted against Executive.

            (b) Except to the extent required by law, Employer following the
Effective Date shall not take any action so as to amend, modify, limit or repeal
the provisions for indemnification of Executive contained in the certificates or
articles of incorporation or by-laws (or other comparable charter documents) of
Employer and its subsidiaries following the Effective Date in such a manner as
would adversely affect the rights of Executive to be indemnified by such
corporations in respect of his serving in such capacities prior to the Effective
Date. Employer following the Effective Date shall honor all of its
indemnification obligations to Executive existing as of the Effective Date and
shall maintain in effect adequate directors' and officer's liability insurance
with respect to such indemnification obligations.

            (c) The provisions of this Section 3.13 are intended to be for the
benefit of, and shall be enforceable by, Executive and his heirs and legal
representatives, and shall be in addition to, and shall not impair, any other
rights Executive may have under Employer's Charter, other organizational
documents of Employer or any of its subsidiaries, the TBCA or otherwise.

      arising out of or relating to my employment with and/or the Separation of
      my employment with the Company and/or any of the other Releasees.

      2. I also agree never to sue any of the Releasees or become party to a
lawsuit on the basis of any claim of any type whatsoever arising out of or
related to my employment with and/or the Separation of my employment with the
Company and/or any of the other Releasees.

      I further agree not to make any public statement or statements, to the
press or otherwise, concerning the Company's Board of Directors, management,
business objectives, status of its securities, its management practices,
products, or other sensitive information, without first receiving the written
consent of the Company's Executive Vice President of Human Resources and its
Chief Executive Officer, and I will not take any action which would cause the
Company, or its employees or agents, embarrassment or humiliation or otherwise
cause or contribute to the Company, or any such person, being held in disrepute
by the general public or the Company's employees, clients, or customers.

      3. I further acknowledge and agree in the event that I breach the
provisions of paragraph 2 above and/or the Non-Solicitation, Non-Compete or
Nondisclosure provisions of the Plan, (a) the Company shall not be obligated to
continue payment of the Severance Pay and the availability of Severance Benefits
to me, (b) I shall be obligated to repay to the Company upon written demand
ninety percent (90%) of the amount of Severance Pay and cost of the Severance
Benefits paid or provided to me, plus simple interest at the rate of ten percent
(10%) per annum from the date of payment of such pay and/or benefits, and (c) I
shall be obligated to pay the Company its costs and expenses in enforcing the
provisions of this Agreement and the Plan (including court costs, expenses and
reasonable legal fees), and the foregoing shall not affect the validity of this
Agreement and shall not be deemed a penalty or a forfeiture. In the event I
breach the notice requirements of Section 4(b) of the Plan regarding eligibility
for alternate welfare plan coverage after a Qualifying Separation, I understand
and agree that the provisions of the prior sentence shall apply, but solely with
respect to the Severance Benefits for which such required notice was not timely
provided. Executive specifically acknowledges that the restrictions,
prohibitions, and other provisions of this paragraph and the Non-Solicitation,
Non-Compete and Nondisclosure restrictions of the Plan are reasonable, fair, and
equitable in scope, terms, and duration, and are a material inducement to the
Company to provide the benefits described in the Plan. Executive agrees that the
obligations in this Agreement are necessary in order to protect the Company's
legitimate business interests; its trade secrets and confidential information;
its relationships with its customers and distributors; its investment in its
employees; and its goodwill, in light of the nature and extent of the business
conducted by the Company. Executive further agrees that upon any breach or
threatened breach of these obligations, the Company shall be entitled to
injunctive relief, both temporary and permanent, without the necessity of
posting a bond, as well as, and in addition to, all other available remedies,
including such damages as may be permitted by law, all of which shall be
cumulative and not exclusive.

      4. I further waive my right to any monetary recovery should any federal,
state, or local administrative agency pursue any claims on my behalf arising out
of or related to my employment with and/or separation from employment with the
Company and/or any of the other Releasees.

      5. I further waive, release, and discharge Releasees from any
reinstatement rights which I have or could have and I acknowledge that I have
not suffered any on-the-job injury for which I have not already filed a claim;
and I hereby unconditionally agree that I shall not now or at any time in the
future, either individually or through others, as an independent contractor or
otherwise in. any capacity, directly or indirectly, apply for or otherwise seek
employment or any other arrangement with the Company and/or any of the other
Releasees to provide services to or on behalf of any of the same, without the
prior written consent of the Executive Vice President of Human Resources of the
Company.

consult with my personal attorney, if desired, before signing below.

within such seven day period to the Plan Administrator. I further understand
that if I revoke this Agreement, I shall not receive Severance Pay or Severance
Benefits.

      8. I FURTHER UNDERSTAND THAT THIS AGREEMENT INCLUDES A RELEASE OF ALL
KNOWN AND UNKNOWN CLAIMS.

      9. I understand that nothing in this Agreement shall affect any obligation
which the Company may have to indemnify me pursuant to Section 9 of the
Company's charter or Article VII of the Company's bylaws.

      10. I acknowledge and agree that this Agreement is given in exchange for
consideration in, addition to anything of value to which I am already entitled.

      11. I acknowledge and agree that if any provision of this Agreement is
found, held or deemed by a court of competent jurisdiction to be void, unlawful
or unenforceable under any applicable statute or controlling law, the remainder
of this Agreement shall continue in full force and effect. If any portion of
this Agreement or the Plan relating to Non-Solicitation, Non-Compete or
Nondisclosure is held by a court of competent jurisdiction to be unreasonable,
unenforceable, arbitrary, or against public policy, then such portion shall be
considered divisible as to time, geographical area, and prohibited activities,
and the remaining provisions shall remain in effect, and the parties agree to
reasonable modification, including but not limited to modifications as to time,
geographical area, and prohibited activities, as the court shall decide in order
to reflect the intent of the parties.
