                              STOCK INCENTIVE PLAN

                                    PREAMBLE

         WHEREAS, Symbion, Inc., formerly known as UniPhy Healthcare, Inc., (the
"Company") established the Symbion, Inc. Stock Option Plan (the "Plan") through
which the Company may award options to purchase the Common Stock of the Company
to directors, officers, employees, and consultants of the Company and its
affiliates;

         WHEREAS, the Company previously adopted the Plan as the Symbion, Inc.
Stock Option Plan and now desires to amend and restate the Plan to increase the
number of shares available for issuance hereunder, to permit the granting of
Stock subject to restrictions on transfer and/or forfeiture, and to change the
name of the Plan to the Symbion Stock Incentive Plan.

         NOW, THEREFORE, the Company hereby amends and restates the Plan,
effective March 28, 2002.

supplement thereto) between the Company or Affiliate and a Participant

the Committee shall be composed of at least two individuals (or such number that
satisfies section 162(m)(4)(C) of the Code and Rule 16b-3 of the Exchange Act)
who are members of the Board and are not employees of the Company or an
Affiliate, and who are designated by the Board as the "compensation committee"
or are otherwise designated to administer the Plan. In the absence of a
designation of a Committee by the Board, the Board shall be the Committee.

                  York Stock Exchange) or is reported on the NASDAQ National
                  Market System or another NASDAQ automated quotation system,

                  price of the Stock on such exchange or system with respect to
                  the date for which Fair Market Value is being determined.

         (b)      If the Stock is not traded on a recognized exchange or

         1.17     Stock.  The Common Stock of the Company.

         1.18 Ten Percent Shareholder. An individual who owns more than 10% of
the total combined voting power of all classes of stock of the Company or an
Affiliate at the time he is granted an Incentive Option. For the purpose of
determining if an individual is a Ten

<PAGE>

Percent Shareholder, he shall be deemed to own any voting stock owned (directly
or indirectly) by or for his brothers and sisters (whether by whole or half
blood), spouse, ancestors or lineal descendants and shall be considered to own
proportionately any voting stock owned (directly or indirectly) by or for a
corporation, partnership, estate or trust of which such individual is a
shareholder, partner or beneficiary.

                               ARTICLE II. PURPOSE

         The purpose of this Plan is to encourage ownership of Stock of the
Company by directors, officers, employees, consultants and advisors of the
Company and any current or future Affiliate. This Plan is intended to provide an
incentive and bonus for maximum effort in the successful operation of the
Company and is expected to benefit the shareholders by associating the interests
of the Company's employees with those of its shareholders and by enabling the
Company to attract and retain personnel of the best available talent through the
opportunity to share, by the proprietary interests created by this Plan, in the
increased value of the Company's shares to which such personnel have
contributed. The benefits of this Plan are not a substitute for compensation
otherwise payable to Company employees pursuant to the terms of their
employment. Proceeds from the purchase of Stock pursuant to this Plan shall be
used for the general business purposes of the Company.

                           ARTICLE III. ADMINISTRATION

         3.1 Administration of Plan. The Plan shall be administered by the
Committee. The express grant in the Plan of any specific power to the Committee
shall not be construed as limiting any power or authority of the Committee. Any
decision made or action taken by the Committee to administer the Plan shall be
final and conclusive. No member of the Committee shall be liable for any act
done in good faith with respect to this Plan or any Agreement or Award. The
Company shall bear all expenses of Plan administration. In addition to all other
authority vested with the Committee under the Plan, the Committee shall have
complete authority to:

         (a)    Interpret all provisions of this Plan;

         (b)    Prescribe the form of any Agreement and notice and manner for
                executing or giving the same;

         (c)    Make amendments to all Agreements;

         (d)    Adopt, amend, and rescind rules for Plan administration; and

         (e)    Make all determinations it deems advisable for the
                administration of this Plan.

         3.2 Authority to Grant Awards. The Committee shall have authority to
grant Awards upon such terms the Committee deems appropriate and that are not
inconsistent with the provisions of this Plan. Such terms may include conditions
on the exercise of all or any part of an Option.

                                       3
<PAGE>

         3.3 Persons Subject to Section 16(b). Notwithstanding anything in the
Plan to the contrary, the Committee, in its absolute discretion, may bifurcate
the Plan so as to restrict, limit or condition the use of any provision of the
Plan to participants who are officers and directors subject to section 16(b) of
the Exchange Act, without so restricting, limiting or conditioning the Plan with
respect to other Participants.

                  ARTICLE IV. AWARD ELIGIBILITY AND LIMITATIONS

         4.1 Participation. The Committee may from time to time designate
directors, officers, employees, consultants and advisors to whom Awards are to
be granted and who are eligible to become Participants. Such designation shall
specify the number of shares of Stock, if any, subject to each Award. All Awards
granted under this Plan shall be evidenced by Agreements that shall be subject
to applicable provisions of this Plan or such other provisions as the Committee
may adopt that are not inconsistent with the Plan.

         4.2 Grant of Awards. An Award shall be deemed to be granted to a
Participant at the time that the Committee designates in a writing that is
adopted by the Committee as the grant of an Award, and that makes reference to
the name of the Participant and the number of shares of Stock that are subject
to the Award. Accordingly, an Award may be deemed to be granted prior to the
approval of this Plan by the shareholders of the Company and prior to the time
that an Agreement is executed by the Participant and the Company.

         4.3 Limitations on Grants. The maximum number of shares with respect to
which Options may be granted to any individual for any calendar year under the
Plan is 10,000,000.

         4.4 Limitations on Incentive Options. A person who is not an employee
of the Company or an Affiliate is not eligible to receive an Incentive Option.
To the extent that the aggregate Fair Market Value of Stock with respect to
which Incentive Options are exercisable for the first time by a Participant
during any calendar year (under all stock incentive plans of the Company and its
Affiliates) exceeds $100,000 (or the amount specified in section 422 of the
Code), determined as of the date an Incentive Option is granted, such Options
shall be treated as Nonqualified Options. This provision shall be applied by
taking Incentive Options into account in the order in which they were granted.

         4.5 Restricted Stock. An award of Restricted Stock to a Participant is
a grant of Stock that is subject to forfeiture and/or restrictions on transfer
that are identified in an Agreement. The Committee may grant Restricted Stock to
a Participant as part of a "deposit share," "performance award" or any other
arrangement established by the Committee and specified in an Agreement. A
Participant who receives Restricted Stock shall be treated as a shareholder of
the Company for all purposes, except that the rights of the Participant may be
limited under the terms of the Agreement. Unless otherwise specified in an
Agreement, Participants shall be entitled to receive dividends on and exercise
voting rights with respect to shares of Restricted Stock.

                                       4
<PAGE>

                        ARTICLE V. STOCK SUBJECT TO PLAN

         5.1 Source of Shares. Upon the exercise of an Option or the grant of
Restricted Stock, the Company shall deliver to the Participant authorized but
previously unissued Stock or Stock that is held by the Company as treasury
stock.

         5.2 Maximum Number of Shares. The maximum number of shares of Company
Stock available for issuance under the Plan shall not exceed the lesser of
28,125,000 shares or 12.5% of the total number of shares then outstanding on a
fully diluted basis (assuming exercise of all outstanding options and warrants
and conversion of all convertible preferred stock), subject to increases and
adjustments as provided in this Article 5 and Article 8, provided, however, that
no adjustment shall be made for any stock split or reverse stock split approved
by the Board within 12 months of its approval this Plan.

         5.3 Forfeitures. If any Option granted hereunder expires or terminates
for any reason without having been exercised in full, or Restricted Stock is
forfeited, the shares of Stock subject thereto shall again be available for
issuance of an Award under this Plan.

               ARTICLE VI. OPTION EXERCISE AND SHAREHOLDER RIGHTS

         6.1 Exercise Price. The exercise price of an Incentive Option shall not
be less than 100% of the Fair Market Value of a share of Stock on the date the
Incentive Option is granted. In the case of a Ten Percent Shareholder, however,
the exercise price of an Incentive Option shall not be less than 110% of the
Fair Market Value of a share of Stock on the date the Incentive Option is
granted. The exercise price of a Nonqualified Option shall not be less than 85%
of the Fair Market Value of a share of Stock on the date of grant.

         6.2 Right to Exercise. An Option may be exercisable on the date of
grant or on such other date(s) established by the Committee or provided for in
an Agreement, provided, however, that Options granted to officers or directors
subject to section 16 of the Exchange Act shall not be exercisable or
transferable, and restrictions on Restricted Stock shall not lapse, until at
least six months after the Award is granted.

         6.3 Maximum Exercise Period. The maximum period in which an Option may
be exercised shall be determined by the Committee on the date of grant except
that no Incentive Option shall be exercisable after the expiration of 10 years
(five years in the case of Incentive Options granted to a Ten Percent
Shareholder) from the date it was granted. A Participant must exercise an
Incentive Option while he is an employee of the Company or an Affiliate, or
within three months of termination of employment with the Company and its
Affiliates (one year in the case of termination due to disability or death).

         6.4 Transferability. Any Award granted under this Plan shall not be
transferable except by will or by the laws of descent and distribution, and
shall be exercisable during the lifetime of the Participant only by the
Participant; provided, however, that a Nonqualified Option or Restricted Stock
may be transferable to the extent provided in an Agreement. No right or interest
of a Participant in any Award shall be liable for, or subject to, any lien,
obligation or liability of such Participant.

                                       5
<PAGE>

         6.5 Shareholder Rights. No Participant shall have any rights as a
shareholder with respect to shares subject to Options prior to the Date of
Exercise of such Option. A Participant's rights as a shareholder with respect to
Restricted Stock shall be determined as provided in Section 4.4.

         6.6 Employee Status. The Committee shall determine the extent to which
a leave of absence for military or government service, illness, temporary
disability, or other reasons shall be treated as a termination or interruption
of employment for purposes of determining questions of forfeiture and exercise
of an Award after termination of employment. With respect to an Incentive
Option, such period of unemployment that is longer than three months following
termination may be treated as employment if consistent with section 422 of the
Code pursuant to a federal statute, Treasury Regulation, or a published ruling
of the Internal Revenue Service that has general application.

                         ARTICLE VII. METHOD OF EXERCISE

         7.1 Exercise. An Option granted hereunder shall be deemed to have been
exercised on the Date of Exercise. Subject to the provisions of Articles VI and
IX, an Option may be exercised in whole or in part at such times and in
compliance with such requirements as the Committee shall determine.

         7.2 Payment. Except as otherwise provided by the Agreement, payment of
the Option price shall be made in cash (including an exercise involving the
pledge of shares and a loan through a broker described in Securities and
Exchange Commission Regulation T), Stock that was acquired at least six months
prior to the exercise of the Option, other consideration acceptable to the
Committee, or a combination thereof.

         7.3 Federal Withholding Tax Requirements. For a Participant who is an
employee of the Company or an Affiliate, upon the exercise of a Nonqualified
Option or the lapse of restrictions on Restricted Stock, the Participant shall,
upon notification of the amount due, pay to the Company amounts necessary to
satisfy applicable federal, state and local withholding tax requirements or
shall otherwise make arrangements satisfactory to the Company for such
requirements. Such withholding requirements shall not apply to the exercise of
an Incentive Option, or to a disqualifying disposition of Stock that is acquired
with an Incentive Option, unless the Committee gives the Participant notice that
withholding described in this Section is required.

         7.4 Issuance and Delivery of Shares. Shares of Stock issued pursuant to
the exercise of Options hereunder shall be delivered to Participants by the
Company (or its transfer agent) as soon as administratively feasible after a
Participant exercises an Option hereunder, or is granted Restricted Stock, and
executes any applicable shareholder agreement or agreement described in Section
9.2 that the Company requires at the time of exercise.

                 ARTICLE VIII. ADJUSTMENT UPON CORPORATE CHANGES

         8.1 Adjustments to Shares. The maximum number of shares of Stock with
respect to which Awards hereunder may be granted and which are the subject of

                                       6
<PAGE>

outstanding Awards shall be adjusted as the Committee determines (in its sole
discretion) to be appropriate, in the event that:

         (a)   the Company or an Affiliate effects one or more Stock dividends,
               Stock splits, reverse Stock splits, subdivisions, consolidations
               or other similar events;

         (b)   the Company or an Affiliate engages in a transaction to which
               section 424 of the Code applies; or

         (c)   there occurs any other event that in the judgment of the
               Committee necessitates such action;

provided, however, that if an event described in paragraph (a) or (b) occurs,
the Committee shall make adjustments to the limits on Awards specified in
Section 5.2 that are proportionate to the modifications of the Stock that are on
account of such corporate changes. Notwithstanding the foregoing, the Committee
may not modify the Plan or the terms of any Awards then outstanding or to be
granted hereunder to provide for the issuance under the Plan of a different
class of stock or kind of securities.

         8.2 Substitution of Awards on Merger or Acquisition. The Committee may
grant Awards in substitution for stock awards, stock options, stock appreciation
rights or similar awards held by an individual who becomes an employee of the
Company or an Affiliate in connection with a transaction to which section 424(a)
of the Code applies. The terms of such substituted Options shall be determined
by the Committee in its sole discretion, subject only to the limitations of
Article V.

         8.3 Effect of Certain Transactions. The provisions of this Section
shall apply to the extent that an Agreement does not otherwise expressly address
the matters contained herein. If the Company experiences an event which results
in a "Change in Control," as defined in Section 8.3(a), then, whether or not the
vesting requirements set forth in any Agreement have been satisfied, (i) all
shares of Restricted Stock that are outstanding at the time of the Change in
Control shall become fully vested and all restrictions shall lapse upon the
Change in Control event, and (ii) all Options that are outstanding at the time
of the Change in Control shall become fully vested and exercisable immediately
prior to the Change in Control event.

         (a)   A Change in Control will be deemed to have occurred for purposes
               hereof, if any one of the following events occur:

                        (1) An acquisition (other than directly from the
               Company) of any voting securities of the Company (the "Voting
               Securities") by any "Person" (as that term is used for purposes
               of Section 13(d) or 14(d) of the Securities Exchange Act of 1934,
               as amended (the "Exchange Act")), immediately after which such
               Person has "Beneficial Ownership" (within the meaning of Rule
               13d-3 promulgated under the Exchange Act) of more than fifty
               percent (50%) of the combined voting power of the Company's then
               outstanding Voting Securities; provided, however, in determining
               whether a Change in Control has occurred, Voting Securities which
               are acquired in a Non-Control Acquisition shall not constitute an
               acquisition which would cause a Change

                                       7
<PAGE>

               in Control. A "Non-Control Acquisition" shall mean an acquisition
               by (1) an employee benefit plan (or a trust forming a part
               thereof) maintained by (A) the Company, or (B) any corporation or
               other Person of which a majority of its voting power or its
               voting equity securities or equity interest is owned, directly or
               indirectly, by the Company (for purposes of this definition, a
               "Subsidiary"), (2) the Company or its Subsidiaries, or (3) any
               Person in connection with a Non-Control Transaction (as
               hereinafter defined);

                        (2) The individuals who, as of the date of this Plan,
               are members of the Company's Board of Directors (the "Incumbent
               Board"), cease for any reason to constitute at least a majority
               of the members of the Company's Board of Directors; provided,
               however, that if the election, or nomination for election by the
               Company's stockholders, of any new director was approved by a
               vote of at least a majority of the Incumbent Board, such new
               director shall, for purposes of this Plan, be considered as a
               member of the Incumbent Board; provided, further, however, that
               no individual shall be considered a member of the Incumbent Board
               if such individual initially assumed office as a result of either
               an actual or threatened "Election Contest" (as described in Rule
               14a-11 promulgated under the Exchange Act) or other actual or
               threatened solicitation of proxies or consents by or on behalf of
               a Person other than the Company's Board of Directors (a "Proxy
               Contest") including by reason of any agreement intended to avoid
               or settle any Election Contest or Proxy Contest; or

                        (3) Approval by stockholders of the Company of:

                                 (i) A merger, consolidation or reorganization
                        involving the Company, unless such merger, consolidation
                        or reorganization is a Non-Control Transaction. A
                        "Non-Control Transaction" shall mean a merger,
                        consolidation or reorganization of the Company where:

                                          (A) the stockholders of the Company,
                                 immediately before such merger, consolidation
                                 or reorganization, own directly or indirectly
                                 immediately following such merger,
                                 consolidation or reorganization, more than
                                 fifty percent (50%) of the combined voting
                                 power of the outstanding voting securities of
                                 the corporation resulting from such merger or
                                 consolidation or reorganization (the "Surviving
                                 Corporation") in substantially the same
                                 proportion as their ownership of the Voting
                                 Securities immediately before such merger,
                                 consolidation or reorganization; and

                                          (B) the individuals who were members
                                 of the Incumbent Board immediately prior to the
                                 execution of the agreement providing for such
                                 merger, consolidation or reorganization

                                          (ii) A complete liquidation or
                                 dissolution of the Company; or

                                          (iii) An agreement for the sale or
                                 other disposition of all or substantially all

                                 (other than a transfer to a Subsidiary).

         (b)   Notwithstanding the foregoing, a Change in Control shall not be
               deemed to occur solely because any Person (the "Subject Person")
               acquired Beneficial Ownership of more than the permitted amount
               of the then outstanding Voting Securities as a result of the
               acquisition of Voting Securities by the Company which, by
               reducing the number of Voting Securities then outstanding,
               increases the proportional number of shares Beneficially Owned by
               the Subject Person, provided that if a Change in Control would
               occur (but for the operation of this sentence) as a result of the
               acquisition of Voting Securities by the Company, and after such
               share acquisition by the Company, the Subject Person becomes the
               Beneficial Owner of any additional Voting Securities which
               increases the percentage of the then outstanding Voting
               Securities Beneficially Owned by the Subject Person, then a
               Change in Control shall occur.

         (c)   Notwithstanding anything to the contrary contained herein, a
               change in ownership that occurs as a result of a public offering
               of the Company's equity securities that is approved by the Board
               shall not alone constitute a Change in Control.

         8.4 No Adjustment upon Certain Transactions. The issuance by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, for cash or property, or for labor or services rendered,
either upon direct sale or upon the exercise of rights or warrants to subscribe
therefor, or upon conversion of shares or obligations of the Company convertible
into such shares or other securities, shall not affect, and no adjustment by
reason thereof shall be made with respect to, outstanding Awards.

         8.5 Fractional Shares. Only whole shares of Stock may be acquired
through the exercise of an Option. Any amounts tendered in the exercise of an
Option remaining after the maximum number of whole shares have been purchased

         (a)   12 months before or after the date of adoption, any amendment
               that increases the aggregate number of shares of Stock that may
               be issued under Incentive Options or changes the employees (or

specified in Section 5.2 is increased by an amendment to this Plan, Incentive
Options may be awarded with respect to such increased shares for a period of ten
years after the earlier of the date that the amendment to the Plan is adopted by
the Board or the date that the amendment is approved by shareholders in a manner
that satisfies Treasury Regulation section 1.422-5. Incentive Options granted
before such dates shall remain valid in accordance with their terms.

         10.8 Effective Date of Plan. The Plan has been adopted by the Board and
was approved by the shareholders of the Company on March 28, 2002 which is the

to the extent that the terms of this restated Plan would have a material adverse
effect on the rights of a Participant under an outstanding Option, unless the
Participant has given consent to the change.

directors with those of its shareholders and by enabling the Company to attract
and retain directors of the best available talent through the opportunity to
share, by the proprietary interests created by this Plan, in the increased
value of the Company's shares to which such directors have contributed. It is
further intended that such incentives will encourage individuals to remain in
the directorship of the Company. The proceeds received by the Company from the
sale of Stock pursuant to this Plan may be used for general corporate purposes.

final and conclusive. No member of the Committee shall be liable for any act
done in good faith with respect to this Plan or any Agreement or Option. The
Company shall bear all expenses of Plan administration. In

Plan with respect to other Participants.

                           ARTICLE IV. OPTION AWARDS

         4.1      Participation. The Committee may from time to time designate
directors to whom Options are to be granted. Such designation shall specify the
number of shares of Stock, if any, subject to each Option. All Options granted
under this Plan shall be evidenced by Agreements which shall be subject to
applicable provisions of this Plan or such other provisions as the Committee

                  (a)      Price. The price at which each share of Stock
         covered by an Option shall be the Fair Market Value of Stock on the
         grant date of such Option.

                  (b)      Option Period. The period within which each Option
         may be exercised shall commence one year after each grant date and

                  detrimental to the interests of the Company or any direct or
                  indirect majority-owned subsidiary of the Company, the Option
                  shall automatically terminate as of the date of such
                  termination.

                  expiration of the Option, the Option

<PAGE>

                  may be exercised, to the extent that the Participant was
                  entitled to exercise it on the date thereof, within one year
                  after such death or disability.

                           (3)      If the directorship of a Participant is
                  terminated for any reason other than the circumstances
                  described in subparagraph (1) or (2) above, the Option may be
                  exercised, to the extent the Participant was able to do so at
                  the date of termination of the directorship, within twelve
                  months after such termination unless extended by a majority
                  of the disinterested Directors. Notwithstanding the
                  foregoing, if the Participant becomes an employee of the
                  Company or an Affiliate upon the termination of his
                  directorship, the Option shall expire after the termination
                  of employment in a manner that is consistent with this
                  subparagraph (3).

         4.2      Options Agreements. All Options granted under this Plan shall
be evidenced by Agreements which shall be subject to applicable provisions of
this Plan and such other provisions as the Committee may adopt that are not

shares of Stock that may be issued pursuant to the exercise of Options shall
not exceed the lesser of 1,687,500 shares or 3/4% of the total number of shares
then outstanding on a fully diluted basis (assuming exercise of all outstanding
options and warrants and conversion of all convertible preferred stock),
subject to increases and adjustments as provided in this Article 5 and Article
8, provided, however, that no adjustment shall be made for any stock split or
reverse stock split approved by the Board within 12 months of its approval this
Plan.

         5.3      Forfeitures. If any Option granted hereunder expires or
terminates for any reason without having been exercised in full, the shares of
Stock subject thereto shall again be available for issuance of an Option under
this Plan.

                           ARTICLE VI. OPTION RIGHTS

         6.1      Transferability. Any Option granted under this Plan shall not
be transferable except by will or by the laws of descent and distribution, and

extent provided in an Agreement. No right or interest of a Participant in any
Option shall be liable for, or subject to, any lien, obligation or liability of
such Participant.

         6.2      Shareholder Rights. No Participant shall have any rights as a
shareholder with respect to shares subject to Options prior to the Date of
Exercise of such Option.

<PAGE>

         6.3      Interruption of Service. The Committee shall determine the
extent to which a leave of absence for military or government service, illness,
temporary disability, or other reasons shall be treated as a termination or
interruption of service as a member of the board for purposes of determining
questions of forfeiture and exercise of an Option after termination.

                          ARTICLE VII. OPTION EXERCISE

         7.1      Exercise. An Option granted hereunder shall be deemed to have
been exercised on the Date of Exercise. Subject to the provisions of Articles
VI and IX, an Option may be exercised in whole or in part at such times and in
compliance with such requirements as the Committee shall determine.

         7.2      Payment. Unless otherwise provided by the Agreement, payment
of the Option price shall be made in cash (including an exercise involving the
pledge of shares and a loan through a broker described in Securities Exchange
Commission Regulation T), Stock that was acquired at least six months prior to
the exercise of the Option, or a combination thereof.

         7.3      Federal Withholding Tax Requirements. To the extent that
withholding is required by law, at the time that an Option is exercised, the
Participant shall, upon notification of the amount due, pay to the Company
amounts necessary to satisfy applicable federal, state and local withholding
tax requirements or shall otherwise make arrangements satisfactory to the
Company for such requirements.

         7.4      Issuance and Delivery of Shares. Shares of Stock issued
pursuant to the exercise of Options hereunder shall be delivered to
Participants by the Company (or its transfer agent) as soon as administratively
feasible after a Participant exercises an Option hereunder and executes any
applicable shareholder agreement or agreement described in Section 9.2 that the
Company requires at the time of exercise.

                ARTICLE VIII. ADJUSTMENT UPON CORPORATE CHANGES

         8.1      Adjustments to Shares. The maximum number of shares of stock
with respect to which Options hereunder may be granted and which are the
subject of outstanding Options shall be adjusted as the Committee determines
(in its sole discretion) to be appropriate, in the event that:

         (a)      the Company or an Affiliate effects one or more stock
                  dividends, stock splits, reverse stock splits, subdivisions,
                  consolidations or other similar events;

         (b)      the Company or an Affiliate engages in a transaction to which
                  section 424 of the Code applies; or

         (c)      there occurs any other event which in the judgment of the
                  Committee necessitates such action;

                                       5

<PAGE>

provided, however, that if an event described in paragraph (a) or (b) occurs,
the Committee shall make adjustments to the limits on Options specified in
Section 5.2 that are proportionate to the modifications of the Stock that are
on account of such corporate changes. Notwithstanding the foregoing, the
Committee may not modify the Plan or the terms of any Options then outstanding
or to be granted hereunder to provide for the issuance under the Plan of a
different class of stock or kind of securities.

         8.2      Substitution of Options on Merger or Acquisition. The
Committee may grant Options in substitution for stock awards, stock options,
stock appreciation rights or similar awards held by an individual who becomes
an employee of the Company or an Affiliate in connection with a transaction to
which section 424(a) of the Code applies. The terms of such substituted Options
shall be determined by the Committee in its sole discretion, subject only to
the limitations of Article V.

         8.3      Effect of Certain Transactions. The provisions of this
Section shall apply to the extent that an Agreement does not otherwise
expressly address the matters contained herein. If the Company experiences an
event which results in a "Change in Control," as defined in Section 8.3(a), all
Options that are outstanding at the time of the Change in Control shall become
fully vested and exercisable immediately prior to the Change in Control event,
except as otherwise provided in paragraph (c) of this Section.

         (a)      A Change in Control will be deemed to have occurred for
                  purposes hereof, if:

                  (1)      any "person" as such term is used in Sections 13(d)
                           and 14(d) of the Exchange Act, other than a
                           Controlled Group Member or an individual who is a
                           shareholder on the date of the adoption of this
                           amendment and restatement of the Plan by the Board,
                           becomes the "beneficial owner" (as defined in Rule
                           13d-3 under said Act), directly or indirectly, of
                           securities of the Company representing more than 50%
                           of the total voting power represented by the
                           Company's then outstanding Voting Securities (as
                           defined below), or

                  (2)      the shareholders of the Company approve a merger or
                           consolidation of the Company with any other
                           corporation, other than a merger or consolidation
                           which would result in the Voting Securities of the
                           Company or a Controlled Group Member outstanding
                           immediately prior thereto continuing to represent
                           (either by remaining outstanding or by being
                           converted into Voting Securities of the surviving
                           entity) more than 50% of the total voting power
                           represented by the Voting Securities of the Company
                           or such surviving entity outstanding immediately
                           after such merger or consolidation, or

                  (3)      the shareholders of the Company approve a plan of
                           complete liquidation of the Company or an agreement
                           for the sale or disposition by the Company of all or
                           substantially all of its assets.

                                       6

                  For purposes of this Section 8.3(a), "Voting Securities" of
                  an entity shall mean any securities of the entity which vote
                  generally in the election of its directors.

         (b)      If, as a result of the Change in Control, the Company is not
                  the surviving entity after the transaction, or survives only
                  as a subsidiary or is otherwise controlled by another entity,
                  all Options that are held by the Participant immediately
                  after the Change in Control shall be assumed by the entity
                  which is the survivor of the transaction, or converted into
                  options to purchase the common stock of the surviving entity,
                  in a transaction to which section 424(a) of the Code applies.

         (c)      Notwithstanding the foregoing, a portion of the acceleration
                  of vesting described in this Section shall not occur with
                  respect to an Option to the extent such acceleration of
                  vesting would cause the Participant or holder of such Option
                  to realize less income, net of taxes, after deducting the
                  amount of excise taxes that would be imposed pursuant to
                  section 4999 of the Code, than if accelerated vesting of that
                  portion of the Option did not occur. This limitation shall
                  not apply to the extent that the shareholders of the Company
                  or the acquirer approve the acceleration of vesting hereunder
                  in a manner that satisfies section 280G(b)(5)(B) of the Code.

         (d)      Notwithstanding anything to the contrary contained herein, a
                  change in ownership that occurs as a result of a public
                  offering of the Company's equity securities that is approved
                  by the Board shall not alone constitute a Change in Control.

         8.4      No Adjustment Upon Certain Transactions. The issuance by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, for cash or property, or for labor or services rendered,
either upon direct sale or upon the exercise of rights or warrants to subscribe
therefor, or upon conversion of shares or obligations of the Company
convertible into such shares or other securities, shall not affect, and no
adjustment by reason thereof shall be made with respect to, outstanding
Options.

         8.5      Fractional Shares. Only whole shares of Stock may be acquired
through the exercise of an Option. Any amounts tendered in the exercise of an
Option remaining after the maximum number of whole shares have been purchased
will be returned to the Participant.

                    ARTICLE IX. LEGAL COMPLIANCE CONDITIONS

         9.1      General. No Option shall be exercisable, no Stock shall be
issued, no certificates for shares of Stock shall be delivered, and no payment
shall be made under this Plan except in compliance with all federal or state
laws and regulations (including, without limitation, withholding tax
requirements), federal and state securities laws and regulations and the rules
of all securities exchanges or self-regulatory organizations on which the
Company's shares may be listed. The Company shall have the right to rely on an
opinion of its counsel as to such compliance. Any certificate issued to
evidence shares of Stock for

                                       7

<PAGE>

which an Option is exercised may bear such legends and statements as the
Committee upon advice of counsel may deem advisable to assure compliance with
federal or state laws and regulations. No Option shall be exercisable, no Stock
shall be issued, no certificate for shares shall be delivered and no payment
shall be made under this Plan until the Company has obtained such consent or
approval as the Committee may deem advisable from any regulatory bodies having
jurisdiction over such matters.

         9.2      Representations by Participants. As a condition to the
exercise of an Option, the Company may require a Participant to represent and
warrant at the time of any such exercise that the shares are being purchased
only for investment and without any present intention to sell or distribute
such shares. At the option of the Company, a stop transfer order against any
shares of stock may be placed on the official stock books and records of the
Company, and a legend indicating that the stock may not be pledged, sold or
otherwise transferred unless an opinion of counsel was provided (concurred in
by counsel for the Company) and stating that such transfer is not in violation
of any applicable law or regulation may be stamped on the stock certificate in
order to assure exemption from registration. The Committee may also require
such other action or agreement by the Participants as may from time to time be
necessary to comply with federal or state securities laws. This provision shall
not obligate the Company or any Affiliate to undertake registration of options
or stock hereunder.

                         ARTICLE X. GENERAL PROVISIONS

         10.1     Effect on Employment. Neither the adoption of this Plan, its
operation, nor any documents describing or referring to this Plan (or any part
thereof) shall confer upon any employee any right to continue in the employ of
the Company or an Affiliate or in any way affect any right and power of the
Company or an Affiliate to terminate the employment of any employee at any time
with or without assigning a reason therefor.

         10.2     Unfunded Plan. The Plan, insofar as it provides for grants,
shall be unfunded, and the Company shall not be required to segregate any
assets that may at any time be represented by grants under this Plan. Any
liability of the Company to any person with respect to any grant under this
Plan shall be based solely upon contractual obligations that may be created
hereunder. No such obligation of the Company shall be deemed to be secured by
any pledge of, or other encumbrance on, any property of the Company.

         10.3     Rules of Construction. Headings are given to the articles and
sections of this Plan solely as a convenience to facilitate reference. The
masculine gender when used herein refers to both masculine and feminine. The
reference to any statute, regulation or other provision of law shall be
construed to refer to any amendment to or successor of such provision of law.

         10.4     Governing Law. The internal laws of the State of Tennessee
(without regard to the choice of law provisions of Tennessee) shall apply to
all matters arising under this Plan, to the extent that federal law does not
apply.

         10.5     Compliance With Section 16 of the Exchange Act. In the event
that any common class of equity securities of the Company becomes subject to
registration under

                                       8

<PAGE>

section 12 of the Exchange Act, transactions under this Plan are intended to
comply with all applicable conditions of Rule 16b-3 or its successors under the
Exchange Act. To the extent any provision of this Plan or action by Committee
fails to so comply, it shall be deemed null and void to the extent permitted by
law and deemed advisable by the Committee.

         10.6     Amendment. The Board may amend or terminate this Plan at any
time; provided, however, an amendment that would have a material adverse effect
on the rights of a Participant under an outstanding Option is not valid with
respect to such Option without the Participant's consent. Provided, further,
that in the event that a common class of equity securities of the Company
becomes subject to registration under section 12 of the Exchange Act, the
shareholders of the Company must approve, in general meeting before the
effective date thereof, any amendment that changes the number of shares in the
aggregate which may be issued pursuant to Options granted under the Plan except
pursuant to Article VIII. By way of example and not by way of limitation,
shareholder approval shall not be required for minor amendments to the Plan
pursuant to Section 3.1 hereof intended to benefit the administration of the
Plan, for amendments necessitated by changes in legislation or administrative
rules governing the Plan, or for amendments that the Committee deems necessary
to obtain or maintain favorable tax, securities exchange or regulatory
treatment of the Plan for future Participants.

         10.7     Effective Date of Plan. The Plan shall be effective on March
28, 2002.
