reacquired by the Corporation. To the extent that any Award payable in Common
Stock is forfeited, cancelled, returned to the Corporation for failure to

<PAGE>

will no longer be charged against the foregoing maximum share limitations and

the maximum number and kind of shares set forth in Sections 6.1, 7.1, 8.1 and
9.4 hereof, (iii) the number and kind of shares of Common Stock, share units, or

or unit or other right subject to then outstanding Awards, (v) the performance
targets or goals applicable to any outstanding Performance Awards (subject to
such limitations as are considered appropriate for Section 162(m) Awards), or
(vi) any other terms of an Award that are affected by the event. Notwithstanding
the foregoing, in the case of Incentive Stock Options, any such adjustments
shall be made in a manner consistent with the requirements of section 424(a) of
the Code and, to the extent considered advisable by the Committee, in a manner
consistent with the requirements of Section 162(m).

4.   Administration of the Plan

     4.1. Committee Members. The Plan shall be administered by the Committee.
          -----------------
The Committee shall have such powers and authority as may be necessary or
appropriate for the Committee to carry out its functions as described in the
Plan. No member of the Committee shall be liable for any action or determination
made in good faith by the Committee with respect to the Plan or any Award
thereunder.

     4.2. Discretionary Authority. Subject to the express limitations of the
          -----------------------
Plan, the Committee shall have authority in its discretion to determine the
Eligible Persons to whom, and the time or times at which, Awards may be granted,
the number of shares, units or other rights subject to each Award, the exercise,
base or purchase price of an Award (if any), the time or times at which an Award
will become vested, exercisable or payable, the performance criteria,
performance goals and other conditions of an Award, the duration of the Award,
and all other terms of the Award. The Committee shall also have discretionary
authority to interpret the Plan, to make all factual determinations under the
Plan, and to make all other determinations necessary or advisable for Plan
administration. The Committee may prescribe, amend, and rescind rules and
regulations relating to the Plan. All interpretations, determinations, and
actions by the Committee shall be final, conclusive, and binding upon all
parties.

     4.3. Changes to Awards. The Committee shall have the authority to effect,
          -----------------
at any time and from time to time, (i) the cancellation of any or all
outstanding Awards and the grant in substitution therefor of new Awards covering
the same or different numbers of shares of Common Stock and having an exercise
or base price which may be the same as or different than the exercise or base
price of the cancelled Awards, or (ii) the amendment of the terms of any and all
outstanding Awards; provided, however, that no such action by the Committee may
                    --------  ------
adversely impair the rights of a Participant (or any permitted transferee) under
any outstanding Award without the consent of the Participant (or transferee).
The Committee may in its discretion

                                       4
<PAGE>

accelerate the vesting or exercisability of an Award at any time or on the basis
of any specified event.

5.   Eligibility and Awards

     All Eligible Persons are eligible to be designated by the Committee to
receive an Award under the Plan. The Committee has authority, in its sole
discretion, to determine and designate from time to time those Eligible Persons
who are to be granted Awards, the types of Awards to be granted and the number
of shares or units subject to the Awards that are granted under the Plan. Each
Award will be evidenced by an Award Agreement between the Corporation and the
Participant that shall include such terms and conditions (consistent with the
Plan) as the Committee may determine; provided, however, that failure to issue
                                      --------  -------
an Award Agreement shall not invalidate an Award.

6.   Stock Options

     6.1. Grant of Option. An Option may be granted to any Eligible Person
          ---------------
selected by the Committee; provided, however, that only Employees of the
                           --------  -------
Corporation or a Subsidiary shall be eligible to receive Incentive Stock
Options. Subject to the applicable provisions of section 422 of the Code, each
Option shall be designated, in the discretion of the Committee, as an Incentive
Stock Option or a Non-qualified Stock Option. The maximum number of shares of
Common Stock that may be granted under Options to any Participant during any
calendar year shall be limited to 700,000 shares (subject to adjustment as
provided in Section 3.2 hereof).

     6.2. Exercise Price. The exercise price under any Option shall be
          --------------
determined by the Committee; provided, however, that the exercise price per
                             --------  -------
share under an Option shall not be less than 100 percent of the Fair Market
Value per share of the Common Stock on the Date of Grant.

     6.3. Vesting; Term of Option. The Committee, in its sole discretion, shall
          -----------------------
prescribe the time or times at which, or the conditions upon which, an Option or
portion thereof shall become vested and exercisable, and may accelerate the
exercisability of any Option at any time. The period during which a vested
Option may be exercised shall be ten years from the Date of Grant, unless a
shorter exercise period is specified by the Committee in an Award, subject to
such limitations as may apply under an Award relating to the termination of a
Participant's employment or other service with the Corporation or any
Subsidiary.

     6.4. Option Exercise; Withholding. Subject to such terms and conditions as
          ----------------------------
shall be specified in an Award, an Option may be exercised in whole or in part
at any time during the term thereof by written notice to the Corporation,
together with payment of the aggregate exercise price therefor. Payment of the
exercise price shall be made (i) in cash or by cash equivalent, (ii) at the
discretion of the Committee, in shares of Common Stock acceptable to the
Committee, valued at the Fair Market Value of such shares on the date of
exercise, (iii) at the discretion of the Committee, by a delivery of a notice
that the Participant has placed a market sell order (or similar instruction)
with a broker with respect to shares of Common Stock then issuable upon exercise
of the Option, and that the broker has been directed to pay a sufficient portion
of the net proceeds of the sale to the Corporation in satisfaction of the Option
exercise price (conditioned upon the payment of such net proceeds), (iv) at the
discretion of the Committee, by

                                       5
<PAGE>

a combination of the methods described above, or (v) by such other method as may
be approved by the Committee and set forth in the Award. In addition to and at
the time of payment of the exercise price, the Participant shall pay to the
Corporation the full amount of any and all applicable income tax and employment
tax amounts required to be withheld in connection with such exercise, payable
under such of the methods described above for the payment of the exercise price
of the Options as may be approved by the Committee.

     6.5. Limited Transferability of Non-qualified Options. All Options shall
          ------------------------------------------------
be nontransferable except (i) upon the Participant's death, by the Participant's
will or the laws of descent and distribution or (ii) in the case Non-qualified
Stock Options only, on a case-by-case basis as may be approved by the Committee
in its discretion, in accordance with the terms provided below. An Award
Agreement for a Non-qualified Stock Option may provide that the Participant
shall be permitted to, during his or her lifetime and subject to the prior
approval of the Committee at the time of proposed transfer, transfer all or part
of the Option to the Participant's family member (as defined in the Award
Agreement in a manner consistent with the requirements for the Form S-8
registration statement, if applicable). Any such transfer shall be subject to
the condition that it is made by the Participant for estate planning, tax
planning, donative purposes or pursuant to a domestic relations order, and no
consideration (other than nominal consideration) is received by the Participant
therefor. The transfer of a Non-qualified Stock Option may be subject to such
other terms and conditions as the Committee may in its discretion impose from
time to time, including a condition that the portion of the Option to be
transferred be vested and exercisable by the Participant at the time of the
transfer. Subsequent transfers of an Option shall be prohibited other than by
will or the laws of descent and distribution upon the death of the transferee.

     6.6. Additional Rules for Incentive Stock Options.
          --------------------------------------------

     (a) Annual Limits. No Incentive Stock Option shall be granted to a
         -------------
Participant as a result of which the aggregate Fair Market Value (determined as
of the Date of Grant) of the stock with respect to which Incentive Stock Options
are exercisable for the first time in any calendar year under the Plan and any
other stock option plans of the Corporation, any Subsidiary, or any parent
corporation, would exceed the maximum amount permitted under section 422(d) of
the Code. This limitation shall be applied by taking Options into account in the
order in which granted.

     (b) Termination of Employment. An Award of an Incentive Stock Option may
         -------------------------
provide that such Option may be exercised not later than 3 months following
termination of employment of the Participant with the Corporation and all
Subsidiaries, subject to special rules relating to death and disability, as and
to the extent determined by the Committee to be appropriate with regard to the
requirements of section 422 of the Code and Treasury Regulations thereunder.

     (c) Other Terms and Conditions; Nontransferability. Any Incentive Stock
         ----------------------------------------------
Option granted hereunder shall contain such additional terms and conditions, not
inconsistent with the terms of this Plan, as are deemed necessary or desirable
by the Committee, which terms, together with the terms of this Plan, shall be
intended and interpreted to cause such Incentive Stock Option to qualify as an
"incentive stock option" under section 422 of the Code. Such terms shall
include, if applicable, limitations on Incentive Stock Options granted to ten-
percent owners of the Corporation. An Award Agreement for an Incentive Stock
Option may provide that such Option

                                       6
<PAGE>

shall be treated as a Non-qualified Stock Option to the extent that certain
requirements applicable to "incentive stock options" under the Code shall not be
satisfied. An Incentive Stock Option shall by its terms be nontransferable
otherwise than by will or by the laws of descent and distribution, and shall be
exercisable during the lifetime of a Participant only by such Participant.

     (d) Disqualifying Dispositions. If shares of Common Stock acquired by
         --------------------------
exercise of an Incentive Stock Option are disposed of within two years following
the Date of Grant or one year following the transfer of such shares to the
Participant upon exercise, the Participant shall, promptly following such
disposition, notify the Corporation in writing of the date and terms of such
disposition and provide such other information regarding the disposition as the
Committee may reasonably require.

     6.7.  Restrictions on Transfer of Stock. The Committee may, in its sole
           ---------------------------------
discretion, impose in any Award of an Option restrictions on the transferability
of the shares of Common Stock issued upon exercise of such Option. If any such
restrictions are imposed, the Committee may require the Participant to enter
into an escrow agreement providing that the certificates representing the shares
subject to such transfer restrictions will remain in the physical custody of an
escrow holder until such restrictions are removed or have expired. The Committee
may require that certificates representing the shares subject to such
restrictions bear a legend making appropriate reference to the restrictions
imposed. Subject to any restrictions imposed in accordance with this Section
6.7, the Participant will have all rights of a shareholder with respect to any
such shares acquired upon an Option exercise, including the right to vote the
shares and receive all dividends and other distributions paid or made with
respect thereto.


7.   Stock Appreciation Rights

     7.1.  Grant of SARs. A Stock Appreciation Right granted to a Participant is
           -------------
an Award in the form of a right to receive, upon surrender of the right but
without other payment, an amount based on appreciation in the Fair Market Value
of the Common Stock over a base price established for the Award, exercisable at
such time or times and upon conditions as may be approved by the Committee. The
maximum number of shares of Common Stock that may be subject to SARs granted to
any Participant during any calendar year shall be limited to 700,000 shares
(subject to adjustment as provided in Section 3.2 hereof).

     7.2.  Tandem SARs. A Stock Appreciation Right may be granted in connection
           -----------
with an Option, either at the time of grant or at any time thereafter during the
term of the Option. An SAR granted in connection with an Option will entitle the
holder, upon exercise, to surrender such Option or any portion thereof to the
extent unexercised, with respect to the number of shares as to which such SAR is
exercised, and to receive payment of an amount computed as described in Section
7.4 hereof. Such Option will, to the extent and when surrendered, cease to be
exercisable. An SAR granted in connection with an Option hereunder will have a
base price per share equal to the per share exercise price of the Option, will
be exercisable at such time or times, and only to the extent, that a related
Option is exercisable, and will expire no later than the related Option expires.

                                       7
<PAGE>

     7.3. Freestanding SARs. A Stock Appreciation Right may be granted without
          -----------------
any related Option, and in such case, will be exercisable as determined by the
Committee, but in no event after 10 years from the Date of Grant. The base price
of an SAR granted without any related Option shall be determined by the
Committee in its sole discretion; provided, however, that the base price per
                                  --------  -------
share of any such freestanding SAR shall not be less than 100 percent of the
Fair Market Value of the Common Stock on the Date of Grant.

     7.4. Payment of SARs. An SAR will entitle the holder, upon exercise of the
          ---------------
SAR, to receive payment of an amount determined by multiplying: (i) the excess
of the Fair Market Value of a share of Common Stock on the date of exercise of
the SAR over the base price of such SAR, by (ii) the number of shares as to
which such SAR is exercised. Payment of the amount determined under the
foregoing may be made, in the discretion of the Committee, in cash, in shares of
Common Stock valued at their Fair Market Value on the date of exercise, or in a
combination of cash and shares of Common Stock.

8.   Restricted Stock Award

     8.1. Grant of Restricted Stock Awards. An Award of Restricted Stock to a
          --------------------------------
Participant represents shares of Common Stock that are issued subject to such
restrictions on transfer and other incidents of ownership and such forfeiture
conditions as the Committee may determine. The Committee may, in connection with
any Restricted Stock Award, require the payment of a specified purchase price.
The Committee may grant a Restricted Stock Award that is a Section 162(m) Award
(as described in Section 8.2 below), as well as Restricted Stock Awards that are
not Section 162(m) Awards; provided, however, that the maximum number of shares
                           --------  -------
of Common Stock that may be subject to a Restricted Stock Award granted to a
Participant during any one calendar year shall be separately limited to 280,000
shares (subject to adjustment as provided in Section 3.2 hereof).

     8.2. Vesting Requirements. The restrictions imposed on shares granted under
          --------------------
a Restricted Stock Award shall lapse in accordance with the vesting requirements
specified by the Committee in the Award Agreement. Such vesting requirements may
be based on the continued employment of the Participant with the Corporation or
its Subsidiaries for a specified time period or periods, provided that any such
restriction shall not be scheduled to lapse in its entirety earlier than the
first anniversary of the Date of Grant. Such vesting requirements may also be
based on the attainment of specified business goals or measures established by
the Committee in its sole discretion. In the case of any Restricted Stock Award
that is a Section 162(m) Award, any such performance-based vesting requirements
shall be based upon the performance criteria identified in Section 9.3 below,
and the terms of the Award shall otherwise comply with the Section 162(m)
requirements described in Section 9.4 hereof.

     8.3. Restrictions. Shares granted under any Restricted Stock Award may not
          ------------
be transferred, assigned or subject to any encumbrance, pledge, or charge until
all applicable restrictions are removed or have expired, unless otherwise
allowed by the Committee. The Committee may require the Participant to enter
into an escrow agreement providing that the certificates representing the shares
granted or sold under a Restricted Stock Award will remain in the physical
custody of an escrow holder until all restrictions are removed or have expired.
Failure to satisfy any applicable restrictions shall result in the subject
shares of the Restricted

                                       8
<PAGE>

Stock Award being forfeited and returned to the Corporation, with any purchase
price paid by the Participant to be refunded, unless otherwise provided by the
Committee. The Committee may require that certificates representing the shares
granted under a Restricted Stock Award bear a legend making appropriate
reference to the restrictions imposed.

     8.4. Rights as Shareholder. Subject to the foregoing provisions of this
          ---------------------
Section 8 and the applicable Award Agreement, the Participant will have all
rights of a shareholder with respect to the shares granted to him under a
Restricted Stock Award, including the right to vote the shares and receive all
dividends and other distributions paid or made with respect thereto, unless the
Committee determines otherwise at the time the Restricted Stock Award is
granted.

     8.5. Section 83(b) Election. The Committee may provide in an Award
          ----------------------
Agreement that the Restricted Stock Award is conditioned upon the Participant's
refraining from making an election with respect to the Award under section 83(b)
of the Code. Irrespective of whether an Award is so conditioned, if a
Participant makes an election pursuant to section 83(b) of the Code with respect
to a Restricted Stock Award, the Participant shall be required to promptly file
a copy of such election with the Corporation.

9.   Performance Awards

     9.1. Grant of Performance Awards. The Committee may grant Performance
          ---------------------------
Awards under the Plan, which shall be represented by units denominated on the
Date of Grant either in shares of Common Stock (Performance Shares) or in
dollars (Performance Units). The Committee may grant Performance Awards that are
Section 162(m) Awards, as well as Performance Awards that are not Section 162(m)
Awards. At the time a Performance Award is granted, the Committee shall
determine, in its sole discretion, one or more performance periods and
performance goals to be achieved during the applicable performance periods, as
well as such other restrictions and conditions as the Committee deems
appropriate. In the case of Performance Units, the Committee shall also
determine a target unit value or a range of unit values for each Award. No
performance period shall exceed ten years from the Date of Grant. The
performance goals applicable to a Performance Award grant may be subject to such
later revisions as the Committee shall deem appropriate to reflect significant
unforeseen events, such as changes in law, accounting practices or unusual or
nonrecurring items or occurrences. The Committee's authority to make such
adjustments shall be subject to such limitations as the Committee deems
appropriate in the case of a Performance Award that is a Section 162(m) Award.

     9.2. Payment of Performance Awards. At the end of the performance period,
          -----------------------------
the Committee shall determine the extent to which performance goals have been
attained, or a degree of achievement between minimum and maximum levels, in
order to establish the level of payment to be made, if any, and shall determine
if payment is to be made in the form of cash or shares of Common Stock (valued
at their Fair Market Value at the time of payment) or a combination of cash and
shares of Common Stock. Payments of Performance Awards shall generally be made
as soon as practicable following the end of the performance period.

     9.3. Performance Criteria. The performance criteria upon which the payment
          --------------------
or vesting of a Performance Award that is a Section 162(m) Award may be based
shall be limited to

                                       9
<PAGE>

one or more of the following business measures, which may be applied with
respect to the Corporation, any Subsidiary or any business unit, and which may
be measured on an absolute or relative to peer-group basis: (i) total
shareholder return, (ii) stock price increase, (iii) return on equity, (iv)
return on capital, (v) earnings per share, (vi) EBIT (earnings before interest
and taxes), and (vii) cash flow (including operating cash flow, free cash flow,
discounted cash flow return on investment, and cash flow in excess of costs of
capital). In the case of Performance Awards that are not Section 162(m) Awards,
the Committee shall designate performance criteria from among the foregoing or
such other business criteria as it shall determine in its sole discretion.

     9.4.  Section 162(m) Requirements. In the case of a Performance Award that
           ---------------------------
is a Section 162(m) Award, the Committee shall make all determinations necessary
to establish the terms of the Award within 90 days of the beginning of the
performance period (or such other time period as is required under Section
162(m)), including, without limitation, the designation of the Participant to
whom the Performance Award is to be made, the performance criteria or criterion
applicable to the Award and the performance goals that relate to such criteria,
and the dollar amounts or number of shares of Common Stock payable upon
achieving the applicable performance goals. As and to the extent required by
Section 162(m), the terms of a Performance Award that is a Section 162(m) Award
must state, in terms of an objective formula or standard, the method of
computing the amount of compensation payable under the Award, and must preclude
discretion to increase the amount of compensation payable under the terms of the
Award (but may give the Committee discretion to decrease the amount of
compensation payable). The maximum amount of compensation that may be payable to
a Participant during any one calendar year under a Performance Unit Award shall
be $4.2 million. The maximum number of Common Stock units that may be subject to
a Performance Share Award granted to a Participant during any one calendar year
shall be 280,000 share units (subject to adjustment as provided in Section 3.2
hereof).

10.  Phantom Stock Award

     10.1. Grant of Phantom Stock Awards. A Phantom Stock Award is an Award to a
           -----------------------------
Participant of a number of hypothetical share units with respect to shares of
Common Stock, with an initial value based on the Fair Market Value of the Common
Stock on the Date of Grant. A Phantom Stock Award shall be subject to such
restrictions and conditions as the Committee shall determine. On the Date of
Grant, the Committee shall determine, in its sole discretion, the installment or
other vesting period of the Phantom Stock Award and the maximum value of the
Phantom Stock Award, if any. No vesting period shall exceed 10 years from the
Date of Grant. A Phantom Stock Award may be granted, at the discretion of the
Committee, together with a Dividend Equivalent Award covering the same number of
shares.

     10.2. Payment of a Phantom Stock Awards. Upon the vesting date or dates
           ---------------------------------

to the Fair Market Value of one share of Common Stock upon such vesting dates
(subject to any applicable maximum value) shall be paid with respect to each
Phantom Stock Award unit granted to the Participant. Payment may be made, at the
discretion of the Committee, in cash or in shares of Common Stock valued at
their Fair Market Value on the applicable vesting dates, or in a combination
thereof.

                                      10

payments determined by reference to dividends declared on the Common Stock from
time to time during the term of the Award, which shall not exceed 10 years from
the Date of Grant. Dividend Equivalent Awards may be granted on a stand-alone
basis or in tandem with other Awards. Dividend Equivalent Awards granted on a
tandem basis shall expire at the time the underlying Award is exercised or
otherwise becomes payable to the Participant, or expires.

     11.2. Payment of Dividend Equivalent Awards. Dividend Equivalent Awards
           -------------------------------------
shall be payable in cash or in shares of Common Stock, valued at their Fair
Market Value on either the date the related dividends are declared or the date

Committee. Dividend Equivalent Awards shall be payable to a Participant as soon
as practicable following the time dividends are declared and paid with respect
to the Common Stock, or at such later date as the Committee shall specify in the
Award Agreement. Dividend Equivalent Awards granted with respect to Options
intended to qualify as a Section 162(m) Award shall be payable regardless of
whether the Option is exercised.

12. Change in Control

     12.1  Effect of Change in Control. The Committee may, in an Award
           ---------------------------
Agreement, provide for the effect of a Change in Control on an Award. Such
provisions may include any one or more of the following: (i) the acceleration or
extension of time periods for purposes of exercising, vesting in, or realizing
gain from any Award, (ii) the elimination or modification of performance or
other conditions related to the payment or other rights under an Award, (iii)
provision for the cash settlement of an Award for an equivalent cash value, as
determined by the Committee, or (iv) such other modification or adjustment to an
Award as the Committee deems appropriate to maintain and protect the rights and
interests of Participants upon or following a Change in Control.

     12.2.   Definition of Change in Control. For purposes hereof, a "Change in
             -------------------------------
Control" shall be deemed to have occurred upon the occurrence of any of the
following after the date on which the Corporation becomes a publicly-held
Corporation:

             (i) An acquisition (other than directly from the Corporation) of
     any voting securities of the Corporation (the "Voting Securities") by any
     "Person" (as the term Person is used for purposes of Section 13(d) or 14(d)
     of the Securities Exchange Act of 1934, as amended (the "1934 Act"))
     immediately after which such Person has "Beneficial Ownership" (within the
     meaning of Rule 13d-3 promulgated under the 1934 Act) of twenty percent
     (20%) or more of the combined voting power of the then outstanding Voting
     Securities; provided, however, that in determining whether a Change in
                 --------  -------
     Control has occurred, Voting Securities which are acquired in a "Non-
     Control Acquisition" (as hereinafter defined) shall not constitute an
     acquisition which would cause a Change in Control. A "Non-Control
     Acquisition" shall mean an acquisition by (i) an employee benefit plan (or
     a trust forming a part thereof) maintained by (A) the Corporation or (B)
     any corporation or other Person of which a majority of the voting power or
     the equity

                                      11
<PAGE>

     securities or equity interests is owned directly or indirectly by the
     Corporation (a "Control Subsidiary"), or (ii) the Corporation or any
     Control Subsidiary.

          (ii)  The individuals who, as of the date the Corporation issues any
     class of equity securities required to be registered under Section 12 of
     the 1934 Act, are members of the Board (the "Incumbent Board"), cease for
     any reason to constitute at least two-thirds of the Board; provided,
                                                                --------
     however, that if the election or nomination for election by the
     -------
     Corporation's stockholders of any new director was approved by a vote of at
     least two-thirds of the Incumbent Board, such new director shall, for
     purposes of this Agreement, 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 (1) 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 1934 Act) or other actual or
     threatened solicitation of proxies or consents by or on behalf of a Person
     other than the Board (a "Proxy Contest") including by reason of any
     agreement intended to avoid or settle any Election Contest or Proxy Contest
     or (2) such individual was designated by a Person who has entered into an
     agreement with the Corporation to effect a transaction described in clause
     (i) or (iii) of this Section 12.2; or


          (iii) Consummation, after approval by stockholders of the Corporation,
     of:

                (1)  A merger, consolidation or reorganization involving the
                     Corporation, unless,

                     (A) The stockholders of the Corporation, immediately before
                     such merger, consolidation or reorganization, own, directly
                     or indirectly immediately following such merger,
                     consolidation or reorganization, at least seventy-five
                     percent (75%) of the combined voting power of the
                     outstanding Voting Securities of the corporation resulting
                     from such merger or consolidation or reorganization or its
                     parent corporation (the "Surviving Corporation") in
                     substantially the same proportion as their ownership of the
                     Voting Securities immediately before such merger,
                     consolidation or reorganization;

                     (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
                     constitute at least two-thirds of the members of the board
                     of directors of the Surviving Corporation; and

                     (C) No Person (other than the Corporation, any Control
                     Subsidiary, any employee benefit plan (or any trust forming
                     a part thereof) maintained by the Corporation, the
                     Surviving Corporation or any Control Subsidiary, or any
                     Person who, immediately prior to such merger, consolidation
                     or reorganization, had Beneficial Ownership of twenty
                     percent (20%) or more of the then

                                      12
<PAGE>

                    outstanding Voting Securities) has Beneficial Ownership of
                    twenty percent (20%) or more of the combined voting power of
                    the Surviving Corporation's then outstanding Voting
                    Securities.

               (2)  A complete liquidation or dissolution of the Corporation; or

               (3)  The sale or other disposition of all or substantially all of
                    the assets of the Corporation to any Person (other than a
                    transfer to a Control Subsidiary).

           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 outstanding Voting
Securities as a result of the acquisition of Voting Securities by the
Corporation which, by reducing the number of Voting Securities outstanding,
increased 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
Corporation, and after such share acquisition by the Corporation, 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.

13.  Award Agreements

     13.1. Form of Agreement. Each Award under this Plan shall be evidenced by
           -----------------
an Award Agreement in a form approved by the Committee setting forth the number
of shares of Common Stock, units or other rights (as applicable) subject to the
Award, the exercise, base, or purchase price (if any) of the Award, the time or
times at which an Award will become vested, exercisable or payable, the duration
of the Award, and in the case of Performance Awards, the applicable performance
criteria and goals. The Award Agreement shall also set forth other material
terms and conditions applicable to the Award as determined by the Committee
consistent with the limitations of this Plan. Award Agreements evidencing Awards
that are Section 162(m) Awards shall contain such terms and conditions as may be
necessary to meet the applicable requirements of Section 162(m). Award
Agreements evidencing Incentive Stock Options shall contain such terms and
conditions as may be necessary to meet the applicable provisions of section 422
of the Code.

     13.2. Forfeiture Events. The Committee may specify in an Award that the
           -----------------
Participant's rights, payments and benefits with respect to an Award shall be
subject to reduction, cancellation, forfeiture or recoupment upon the occurrence
of certain specified events, in addition to any otherwise applicable vesting or
performance conditions of an Award. Such events shall include, but shall not be
limited to, termination of employment for cause, violation of material
Corporation or Subsidiary policies, breach of noncompetition, confidentiality or
other restrictive covenants that may apply to the Participant, or other conduct
by the Participant that is detrimental to the business or reputation of the
Corporation or any Subsidiary.

14.  General Provisions

     14.1. No Assignment or Transfer; Beneficiaries. Except as provided in
           ----------------------------------------
Section 6.5 hereof, Awards under the Plan shall not be assignable or
transferable, except by will or by the laws of descent and distribution, and
during the lifetime of a Participant, the Award shall be exercised only by such
Participant or by his guardian or legal representative. Notwithstanding the
foregoing, the Committee may provide in the terms of an Award Agreement that the
Participant shall have the right to designate a beneficiary or beneficiaries who
shall be entitled to any rights, payments or other specified under an Award
following the Participant's death.

     14.2. Deferrals of Payment. Notwithstanding any other provisions of the
           --------------------
Plan, the Committee may permit a Participant to defer the receipt of payment of
cash or delivery of shares of Common Stock that would otherwise be due to the
Participant by virtue of the exercise of a right or the satisfaction of vesting
or other conditions with respect to an Award. If any such deferral is to be
permitted by the Committee, the Committee shall establish the rules and
procedures relating to such deferral, including, without limitation, the period
of time in advance of payment when an election to defer may be made, the time
period of the deferral and the events that would result in payment of the
deferred amount, the interest or other earnings attributable to the deferral and
the method of funding, if any, attributable to the deferred amount.

     14.3. Rights as Shareholder. A Participant shall have no rights as a holder
           ---------------------
of Common Stock with respect to any unissued securities covered by an Award
until the date the Participant becomes the holder of record of such securities.
Except as provided in Section 3.2 hereof, no adjustment or other provision shall
be made for dividends or other shareholder rights, except to the extent that the
Award Agreement is a Dividend Equivalent Award, or otherwise provides for
dividend payments or similar economic benefits.

     14.4. Employment or Service. Nothing in the Plan, in the grant of any Award
           ---------------------
or in any Award Agreement shall confer upon any Eligible Person the right to
continue in the capacity in which he is employed by, or otherwise serves, the
Corporation or any Subsidiary.

     14.5. Securities Laws. No shares of Common Stock will be issued or
           ---------------
transferred pursuant to an Award unless and until all then applicable
requirements imposed by federal and state securities and other laws, rules and
regulations and by any regulatory agencies having jurisdiction, and by any stock
exchanges upon which the Common Stock may be listed, have been fully met. As a
condition precedent to the issuance of shares pursuant to the grant or exercise
of an Award, the Corporation may require the Participant to take any reasonable
action to meet such requirements. The Committee may impose such conditions on
any shares of Common Stock issuable under the Plan as it may deem advisable,
including, without limitation, restrictions under the Securities Act of 1933, as
amended, under the requirements of any stock exchange upon which such shares of
the same class are then listed, and under any blue sky or other securities laws
applicable to such shares.

     14.6. Tax Withholding. The Participant shall be responsible for payment of
           ---------------
any taxes or similar charges required by law to be withheld from an Award or an
amount paid in satisfaction of an Award, which shall be paid by the Participant
on or prior to the payment or other event that results in taxable income in
respect of an Award. The Award Agreement shall

                                      14
<PAGE>

specify the manner in which the withholding obligation shall be satisfied with
respect to the particular type of Award.

     14.7.  Unfunded Plan. The adoption of this Plan and any setting aside of
            -------------
cash amounts or shares of Common Stock by the Corporation with which to
discharge its obligations hereunder shall not be deemed to create a trust or
other funded arrangement. The benefits provided under this Plan shall be a
general, unsecured obligation of the Corporation payable solely from the general
assets of the Corporation, and neither a Participant nor the Participant's
permitted transferees or estate shall have any interest in any assets of the
Corporation by virtue of this Plan, except as a general unsecured creditor of
the Corporation. Notwithstanding the foregoing, the Corporation shall have the
right to implement or set aside funds in a grantor trust, subject to the claims
of the Corporation's creditors, to discharge its obligations under the Plan.

     14.8.  Other Compensation and Benefit Plans. The adoption of the Plan shall
            ------------------------------------
not affect any other stock incentive or other compensation plans in effect for
the Corporation or any Subsidiary, nor shall the Plan preclude the Corporation
from establishing any other forms of stock incentive or other compensation for
employees of the Corporation or any Subsidiary. The amount of any compensation
deemed to be received by a Participant pursuant to an Award shall not constitute
compensation with respect to which any other employee benefits of such
Participant are determined, including, without limitation, benefits under any
bonus, pension, profit sharing, life insurance or salary continuation plan,
except as otherwise specifically provided by the terms of such plan.

     14.9.  Plan Binding on Transferees. The Plan shall be binding upon the
            ---------------------------
Corporation, its transferees and assigns, and the Participant, his executor,
administrator and permitted transferees and beneficiaries.

     14.10. Construction and Interpretation. Whenever used herein, nouns in the
            -------------------------------
singular shall include the plural, and the masculine pronoun shall include the
feminine gender. Headings of Articles and Sections hereof are inserted for
convenience and reference and constitute no part of the Plan.

     14.11. Severability. If any provision of the Plan or any Award Agreement
            ------------
shall be determined to be illegal or unenforceable by any court of law in any
jurisdiction, the remaining provisions hereof and thereof shall be severable and
enforceable in accordance with their terms, and all provisions shall remain
enforceable in any other jurisdiction.

     14.12. Governing Law. The validity and construction of this Plan and of the
            -------------
Award Agreements shall be governed by the laws of the State of Texas.

15.  Effective Date, Termination and Amendment

     15.1.  Establishment of the Plan. This Plan is being adopted by the Board
            -------------------------
in connection with the anticipated formation of the Corporation as a Subsidiary
of Columbia/HCA and the distribution shortly thereafter by Columbia/HCA of all
of its shares of the Corporation to the shareholders of Columbia/HCA.

                                      15

     15.2. Effective Date; Shareholder Approval. The Effective Date of the Plan
           ------------------------------------
shall be the date the Corporation's Common Stock is distributed to Columbia/HCA
Healthcare Corporation stockholders; provided, however, that no amounts may be
                                     --------  -------
paid or shares issued under any Award granted on or after the first meeting of
the shareholders of the Corporation that shall occur more than twelve months
after the date on which the Corporation becomes a publicly held corporation,
unless the shareholders of the Corporation shall have approved the Plan. At the
sole discretion of the Board, in order to comply with the requirements of
Section 162(m) for certain types of Awards under the Plan, the performance
criteria set forth in Section 9.3 shall be reapproved by the shareholders of the
Corporation no later than the first shareholder meeting that occurs in the fifth
calendar year following the calendar year of the initial shareholder approval of
such performance criteria.

     15.3. Termination. The Plan shall terminate on the date immediately
           -----------
preceding the tenth anniversary of the date the Plan is adopted by the Board.
The Board may, in its sole discretion and at any earlier date, terminate the
Plan. Notwithstanding the foregoing, no termination of the Plan shall adversely
affect any Award theretofore granted without the consent of the Participant or
the permitted transferee of the Award.

     15.4. Amendment. The Board may at any time and from time to time and in any
           ---------
respect, amend or modify the Plan; provided, however, that no amendment or
                                   --------  -------
modification of the Plan shall be effective without the consent of the
Corporation's shareholders that would (i) change the class of Eligible Persons
under the Plan, (ii) increase the number of shares of Common Stock reserved for
issuance under the Plan in accordance with Section 3.1 hereof, or (iii) allow
the grant of Options at an exercise price below Fair Market Value. In addition,
the Board may seek the approval of any amendment or modification by the
Corporation's shareholders to the extent it deems necessary or advisable in its
sole discretion for purposes of compliance with Section 162(m) or section 422 of
the Code, the listing requirements of the Nasdaq Stock Market or for any other
purpose. No amendment or modification of the Plan shall adversely affect any
Award theretofore granted without the consent of the Participant or the
permitted transferee of the Award.

                                  Appendix A
                                  ----------

     Notwithstanding anything elsewhere in the Plan to the contrary, the
following rules shall apply in connection with the distribution of Common Stock
to Columbia/HCA stockholders (the "Spin-off").

     (i)    In the case of each Columbia/HCA Non-Qualified Option that is a
            vested option and covers more than 1000 shares, the Committee may
            grant an option which covers a number of shares of Common Stock
            equal to the Original Number of Shares multiplied by the Triad Share
            Multiple and which has a per share exercise price equal to the per
            share exercise price of the original Columbia/HCA Non-Qualified
            Option multiplied by the Triad Ratio.

     (ii)   In the case of each Columbia/HCA ISO that is held by a Triad
            Employee or Triad Terminee (or his estate), the Committee may grant
            an option which covers a number of shares of Common Stock equal to
            the Original Number of Shares divided by the Triad Ratio and (2) has
            a per share exercise price equal to the original per share exercise
            price multiplied by the Triad Ratio.

     (iii)  In the case of any options granted by the Committee pursuant to this
            Appendix, any resulting per share exercise price which is not equal
            to a whole multiple of a cent shall be rounded up to the next whole
            cent and any resulting number of shares covered by an option which
            is not equal to a whole multiple of a share shall be rounded down to
            the next whole share.

     (iv)   The Committee may provide that the terms of any option granted under
            this Appendix are to be substantially the same as those of the
            related Columbia/HCA Option, subject to such exceptions as the
            Committee may provide. Any such option may, in the discretion of the
            Committee, also provide that (a) any period of prior employment or
            service with Columbia/HCA or any related entity is to be credited as
            covered employment or service for purposes of determining the
            vesting and exercisability of such option (to the same extent as
            such period was credited for such purposes under the related
            original Columbia/HCA Option), and (b) in the case of any
            Columbia/HCA Non-Qualified Option, the optionee is to be considered
            to be employed by or providing services to the Corporation so long
            as he is employed by or providing services to Columbia/HCA or
            LifePoint Hospitals, Inc. ("LifePoint") (or any Subsidiary thereof),
            for purposes of determining when the option will cease to be
            exercisable on account of termination of employment or service, and
            at such time as the optionee ceases to be employed by or provide
            services to Columbia/HCA or LifePoint (or any Subsidiary thereof),
            such cessation of employment or service shall be treated as though
            it were a cessation of employment or service with the Corporation
            under comparable circumstances.


     (v)    For purposes hereof, the following definitions shall apply:

            (a)   "Affiliate" shall mean any entity required to be aggregated
                  with Columbia/HCA, LifePoint or Triad as appropriate, pursuant
                  to Code sections 414(b), 414(c), 414(m) or 414(o).

            (b)   "Columbia/HCA ISO" shall mean any option outstanding under a

                             17
<PAGE>

                  Columbia/HCA Option Plan on the date of the Spin-off that is
                  intended to qualify as an "Incentive Stock Option" under
                  section 422 of the Code.

          (c)     "Columbia/HCA Non-Qualified Option" shall mean any stock
                  option outstanding under a Columbia/HCA Option Plan on the
                  date of the Spin-off that is not a Columbia/HCA ISO. Any such
                  option shall be considered a "vested option" to the extent
                  that it is exercisable on the date in question and shall be
                  considered a "non-vested option" to the extent that it is not
                  yet exercisable on such date.

          (d)     "Columbia/HCA Option" shall mean a Columbia/HCA ISO or
                  Columbia/HCA Non-Qualified Option, as the context shall
                  indicate.

          (e)     "Columbia/HCA Option Plan" shall mean any plan maintained by
                  Columbia/HCA under which there are stock options outstanding
                  on the date of the Spin-off.

          (f)     "Ex-Dividend Date" shall mean the first trading date on which
                  the Columbia/HCA stock shall trade on an ex-dividend basis
                  with respect to the distribution of the Corporation's Common
                  Stock and LifePoint's stock.

          (g)     "Original Number of Shares" shall mean, as to any Columbia/HCA
                  Option, the number of shares of Columbia/HCA stock covered by
                  such option immediately prior to the Spin-off.

          (h)     "Triad Business" shall mean any business conducted by Triad,
                  or its Subsidiaries, on the date of the Spin-off.

          (i)     "Triad Employee" shall mean an employee of the Corporation,
                  or any direct or indirect Subsidiary of the Corporation that
                  is an Affiliate thereof, on the date of the Spin-off.

          (j)     "Triad Ratio" shall mean a fraction whose numerator is the
                  closing price of the Common Stock on the trading date
                  immediately preceding the Ex-Dividend Date and whose
                  denominator is the closing price of the Columbia/HCA stock on
                  such trading date immediately preceding the Ex-Dividend Date.

          (k)     "Triad Share Multiple" shall mean the number of shares of
                  Common Stock to be distributed per share of Columbia/HCA stock
                  on the date of the Spin-off.

          (l)     "Triad Terminee" shall mean any individual who is no longer
                  employed by Columbia/HCA or any Affiliate thereof immediately
                  prior to the Spin-off but was employed by a Triad Business
                  immediately prior to his termination of employment from
                  Columbia/HCA and its Affiliates.

     Notwithstanding anything elsewhere in the Plan to the contrary, the
Committee may grant Non-qualified Stock Options, effective as of the twenty-
first trading date for the Common Stock, at an exercise price equal to the Fair
Market Value of the Common Stock on such date, in accordance with the attached
Schedule and in accordance with such other terms as shall be established by the
Committee.
