            (a)  If the Shares, as currently constituted, are changed into or
     exchanged for a different number or kind of shares of stock or other
     securities of the Company or of another corporation (whether because of
     merger, consolidation, recapitalization, reclassification, split, reverse
     split, combination of shares, or otherwise) or if the number of Shares is
     increased through the payment of a stock dividend, then the Committee will
     substitute for or add to each Share previously appropriated, later subject
     to, or which may become subject to, an Award, the number and kind of shares
     of stock or other securities into which each outstanding Share was changed
     for which each such Share was exchanged, or to which each such Share is
     entitled, as the case may be. The Committee, in its sole discretion, also
     may amend outstanding Awards as to price and other terms, to the extent
     necessary to reflect the events described above. If there is any other
     change in the number or kind of the outstanding Shares, of any stock or
     other securities into which the outstanding Shares have been changed, or
     for which they have been exchanged, the Committee, in its sole discretion,
     may adjust any Award already granted or which may be afterward granted.

            (b)  Fractional Shares resulting from any adjustment in Awards
     pursuant to this Section may be settled in cash or otherwise as the
     Committee determines. The Company will give notice of any adjustment to
     each Participant who holds an Award that has been adjusted and the
     adjustment (whether or not such notice is given) will be effective and

Article 6. Stock Options
           -------------

     6.1  Grant of Options. Subject to the terms and provisions of the Plan, the
Committee may grant Options to any Employee, Advisor or non-Employee Director in
the number, and upon the terms, and at any time and from time to time, as the
Committee determines.

     6.2  Award Agreement. Each Option grant will be evidenced by an Award
Agreement that specifies the duration of the Option, the number of Shares to
which the Option pertains, the class of the Company's Common Stock to which the
Option pertains, the manner, time, and rate of exercise and/or vesting of the
Option, and such other provisions as the Committee determines. The Award
Agreement will also specify whether the Option is intended to be an ISO or an
NQSO, and whether reload options will be granted.

     6.3  Exercise Price. Each Option grant and Award Agreement will specify the
Exercise Price for each Share subject to an Option, which will be at least one
hundred percent (100%) of the Share's Fair Market Value on the date the Option
is granted. If the Option is an ISO and the Employee to whom the Option is
granted is a Ten Percent Owner of the Company or an Affiliate, the Exercise
Price for each Share subject to an Option will be at least one hundred ten
percent (110%) of the Share's Fair Market Value on the date the Option is
granted.

     6.4  Duration of Options. Each Option will expire at the time determined by
the Committee at the time of grant and specified in the Award Agreement, but no
later th an the tenth anniversary of the date of its grant.

     If the Option is an ISO and the Employee to whom the Option is granted is a
Ten Percent Owner of the Company or an Affiliate, the Option will expire upon
the earlier of (i) the time specified by the Committee in the Award Agreement,
or (ii) the fifth anniversary of the date of grant.

     6.5  Dividend Equivalents. The Committee may, but shall not be required to,
grant payments in connection with Options that are equivalent to dividends
declared and paid on the Shares underlying the Options. Such dividend equivalent
payments may be made in cash or in Shares, upon such terms as the Committee, in
its sole discretion, deems appropriate.

     6.6  Exercise of Options. Options will be vested and exercisable at such
times and be subject to such restrictions and conditions as the Committee in
each instance approves, which need not be the same for each Award or for each
Participant, and sets forth in the Award Agreement.

     6.7  Payment. The holder of an Option may exercise the Option only by
delivering a written notice of exercise to the Company setting forth the number
of Shares as to which the Option is to be exercised, together with full payment
at the Exercise Price for the Shares as to which the Option is exercised and any
withholding tax relating to the exercise of the Option.

     The Exercise Price per share of Common Stock with respect to each Option
exercise shall be payable in United States dollars, in cash by check made
payable to the Company. If the

                                      -7-
<PAGE>

Common Stock is registered under Section 12(g) of the Securities Act, the
Participant also may pay the exercise price in one of the following forms:

          (a)  in shares of Common Stock the Participant has held for a period
     sufficient to avoid a charge to the Company's earnings for financial
     reporting purposes, with such shares to be valued at the Fair Market Value
     on the date of exercise;

          (b)  through a special sale and remittance procedure pursuant to which
     the Participant concurrently provides irrevocable written instructions to
     (i) a Company-designated brokerage firm to effect the immediate sale of the
     purchased shares and remit to the Company, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price payable for the purchased shares plus all applicable
     Federal, state and local income and employment taxes required to be
     withheld by the Company by reason of such exercise, and (ii) the Company to
     deliver the certificates for the purchased shares directly to such
     brokerage firm in order to complete the sale.

Cashless exercise must meet the requirements of the Federal Reserve Board's
Regulation T and any applicable securities law restrictions.

     The Company will issue, in the name of the Participant (or, if applicable,
the legatee(s), executor(s), personal representative(s), or distributee(s) of a
deceased Participant), stock certificates representing the total number of
shares of Option Stock issuable pursuant to the exercise of any Option as soon
as reasonably practicable after such exercise.

     6.8  Restrictions on Share Transferability. The Committee may impose such
restrictions on any Shares acquired through exercise of an Option as it deems
necessary or advisable, including, without limitation, restrictions under
applicable federal securities laws, under the requirements of any stock exchange
or market upon which the Shares are then listed and/or traded, and under any
blue sky or state securities laws applicable to the Shares.

     6.9  Termination of Service. Each Option Award Agreement will set forth the
extent to which the Participant has the right to exercise the Option after his
or her termination of Service. These terms will be determined by the Committee
in its sole discretion, need not be uniform among all Options, and may reflect,
among other things, distinctions based on the reasons for termination of
Service.

     6.10 Nontransferability of Options. Except as otherwise provided in a
Participant's Award Agreement, no Option granted under the Plan may be sold,
transferred, pledged, assigned, or otherwise alienated or hypothecated, other
than by will or by the laws of descent and distribution. Further, except as
otherwise provided in a Participant's Award Agreement, all Options will be
exercisable during the Participant's lifetime only by the Participant or his or
her guardian or legal representative. The Committee may, in its discretion,
require a Participant's guardian or legal representative to supply it with the
evidence the Committee deems necessary to establish the authority of the
guardian or legal representative to act on behalf of the Participant.

     6.11 Reload Options. The Committee may provide for reload options in the
Award Agreement evidencing an Option. Any reload feature will be subject to the
following requirements:

          (a)  it must not be added to an already outstanding Option, but must
     be part of the Option as originally granted;

          (b)  the reload must be automatic, not subject to the discretion of
     the Committee or anyone else;

          (c)  it must have an Exercise Price at least equal to the Fair Market
     Value of a Share at the time of reload;

          (d)  it may be granted with respect only to previously-owned Shares
     used to pay the Exercise Price of the original Option, and only if the
     Participant has owned the Shares used to pay the Exercise Price for at
     least six months

          (e)  the Award Agreement that contains the reload feature must not
     permit multiple reloads (i.e., no reload Options may be granted on Shares
     acquired through reload Options) and must subject any Option granted on
     reload to a vesting period of at least six months; and

          (f)  it must limit the duration of reload Options, by providing that
     an Option granted on reload expires at the same time as the initial Option
     would have.

     6.12  Limitation on Grant of Incentive Stock Options. The Committee may
grant Incentive Stock Options only to Employees. The Committee will not grant an
Option under this Plan as an incentive stock option if it would cause the
aggregate fair market value of stock with respect to which incentive options are
exercisable by the Participant for the first time during a calendar year (under
all plans of the Company and its Affiliates) to exceed $100,000.

Article 7.  Stock Appreciation Rights
            -------------------------

     7.1  Grant of SARs. Subject to the terms and conditions of the Plan, the
Committee may grant SARs to Employees, Advisors and/or non-employee Directors at
any time and from time to time, as it determines. Within the limits of Article
4, the Committee will have sole discretion to determine the number of SARs
granted to any Employee, Advisor and/or non-employee Director and, consistent
with the provisions of the Plan, to determine the terms and conditions
pertaining to SARs. The grant price of an SAR will equal the Fair Market Value
of a Share on the date of grant of the SAR, and will be specified in the Award
Agreement.

     7.2  Exercise of SARs. SARs may be exercised upon whatever terms and
conditions the Committee, in its sole discretion, imposes and sets forth in the
Award Agreement.

     7.3  Award Agreement. Each SAR grant will be evidenced by an Award
Agreement that specifies the grant price, the term of the SAR and such other
provisions as the Committee determines.

                                      -9-
<PAGE>

     7.4  Term of SARs. The term of an SAR will be determined by the Committee,
in its sole discretion and set forth in the Award Agreement, but may not exceed
ten years.

     7.5  Payment of SAR Amount. Upon exercise of an SAR, a Participant will be
entitled to receive payment from the Company in an amount determined by
multiplying:

          (a)  the excess (or some portion of the excess as determined at the
     time of the grant by the Committee and specified in the Award Agreement) if
     any, of the Fair Market Value on the date of exercise of the SAR over the
     grant price specified in the Award Agreement; by

          (b)  the number of Shares as to which the SAR is exercised.

     At the discretion of the Participant, the payment upon SAR exercise may be
made in cash, in Shares of equivalent Fair Market Value or in some combination
of the two.

     7.6  Termination of Service.  Each SAR Award Agreement will set forth the
extent to which the Participant has the right to exercise the SAR after his or
her termination of Service.  These terms will be determined by the Committee in
its sole discretion, need not be uniform among all SARs issued under the Plan,
and may reflect, among other things, distinctions based on the reasons for
termination of Service.

     7.7  Nontransferability of SARs. Except as otherwise provided in a
Participant's Award Agreement, no SAR may be sold, transferred, pledged,
assigned, or otherwise alienated or hypothecated, other than by will or by the
laws of descent and distribution. Further, except as otherwise provided in a
Participant's Award Agreement, all SARs will be exercisable during the
Participant's lifetime only by the Participant or the Participant's guardian or
legal representative. The Committee may, in its discretion, require a
Participant's guardian or legal representative to supply it with evidence the
Committee deems necessary to establish the authority of the guardian or legal
representative to act on behalf of the Participant.

Article 8.  Restricted Stock
            ----------------

     8.1  Grant of Restricted Stock.  Subject to the terms and provisions of the
Plan, the Committee may, at any time and from time to time, grant Restricted
Stock to Employees, Advisors, and/or non-employee Directors, in such amounts as
the Committee determines.

     8.2  Deferral of Compensation into Restricted Stock. Subject to the terms
and provisions of the Plan, the Committee may, at any time and from time to
time, allow (or require, as to bonuses) selected Employees or non-employee
Directors to defer the payment of any portion of their fees, salary and/or
annual bonuses pursuant to this section. A Participant's deferral under this
section will be credited to the Participant in the form of Shares of Restricted
Stock. The Committee will establish rules and procedures for the deferrals, as
it deems appropriate.

     In consideration for forgoing compensation, the dollar amount deferred by
an Employee or non-employee Director may be increased by twenty-five percent (or
such lesser percentage as

                                      -10-
<PAGE>

the Committee may determine) for purposes of determining the number of Shares of
Restricted Stock to grant the Participant. If a Participant's compensation is
deferred under this Section 8.2, he or she will be credited, as of the date
specified in the Award Agreement, with a number of shares of Restricted Stock
equal to the amount of the deferral (increased as described above) divided by
the Fair Market Value on that date.

     8.3  Award Agreement. Each Restricted Stock grant will be evidenced by an
Award Agreement that specifies the Restriction Periods, the number of Shares
granted, and such other provisions as the Committee determines.

     8.4  Nontransferability. The Restricted Stock granted herein may not be
sold, transferred, pledged, assigned, or otherwise alienated or hypothecated,
other than by will or by the laws of descent and distributions, until the end of
the applicable Restriction Period as specified in the Award Agreement, or upon
earlier satisfaction of any other conditions specified by the Committee in its
sole discretion and set forth in the Award Agreement. All rights with respect to
Restricted Stock will be available during the Participant's lifetime only to the
Participant or the Participant's guardian or legal representative. The Committee
may, in its discretion, require a Participant's guardian or legal representative
to supply it with evidence the Committee deems necessary to establish the
authority of the guardian or legal representative to act on behalf of the
Participant.

     8.5  Other Restrictions. The Committee may impose such other conditions
and/or restrictions on any Restricted Stock as it deems advisable and sets forth
in the applicable Award Agreement including, without limitation, restrictions
based upon the achievement of specific performance objectives (Company-wide,
business unit, and/or individual), time-based restrictions on vesting following
the attainment of the performance objectives, and/or restrictions under
applicable federal or state securities laws. The Committee may provide that
restrictions established under this Section 8.5 as to any given Award will lapse
all at once or in installments.

     The Company may retain the certificates representing Shares of Restricted
Stock in its possession until all conditions and/or restrictions applicable to
the Shares have been satisfied.

     8.6  Payment of Awards. Except as otherwise provided in this Article 8,
Shares covered by each Restricted Stock grant will become freely transferable by
the Participant after the last day of the applicable Restriction Period.

     8.7  Voting Rights. The applicable Award Agreement may specify that, during
the Restriction Period, Participants holding Shares of Restricted Stock may
exercise full voting rights with respect to those Shares.

     8.8  Dividends and Other Distributions. The applicable Award Agreement may
specify that, during the Restriction Period, Participants awarded Shares of
Restricted Stock thereunder will be credited with regular cash dividends paid on
those Shares. Dividends may be paid currently, accrued as contingent cash
obligations, or converted into additional Shares of Restricted Stock, upon such
terms as the Committee establishes and sets forth in the Award Agreement.

                                      -11-
<PAGE>

     The Committee may specify in the applicable Award Agreement, any
restrictions it deems advisable to the crediting and payment of dividends and
other distributions. Without limiting the generality of the preceding sentence,
if the grant or vesting of Restricted Stock is designed to qualify for the
Performance-Based Exception, the Committee may apply any restrictions it deems
appropriate to the payment of dividends declared with respect to the Restricted
Stock, so that the dividends and/or the Restricted Stock continue to be eligible
for the Performance-Based Exception.

     8.9  Termination of Service. Each Award Agreement will set forth the extent
to which the Participant has the right to retain unvested Restricted Stock after
his or her termination of Service. These terms will be determined by the
Committee in its sole discretion, need not be uniform among all Awards of
Restricted Stock, and may reflect, among other things, distinctions based on the
reasons for termination of Service.

Article 9.  Performance Shares
            ------------------

     9.1  Grant of Performance Shares. Subject to the terms of the Plan, the
Committee may grant Performance Shares to Participants in such amounts and upon
such terms, and at any time and from time to time, as the Committee determines
and sets forth in an Award Agreement.

     9.2  Value of Performance Shares. Each Performance Share will have an
initial value equal to the Fair Market Value on the date of grant. The Committee
will set performance objectives in its discretion that, depending on the extent
to which they are met, will determine the number and/or value of Performance
Shares that will be paid out to the Participant. For purposes of this Article 9,
the time period during which the performance objectives must be met will be
called a "Performance Period" and will be set by the Committee in its discretion
          ------------------
and set forth in an Award Agreement.

     9.3  Earning of Performance Shares. Subject to the terms of this Plan,
after the applicable Performance Period has ended, the holder of Performance
Shares will be entitled to receive payout on the number and value of Performance
Shares earned by the Participant over the Performance Period, to be determined
as a function of the extent to which the corresponding performance objectives
have been achieved.

     9.4  Award Agreement. Each grant of Performance Shares will be evidenced by
an Award Agreement specifying the material terms and conditions of the Award
including the form of payment of earned Performance Shares, the class of Common
Stock to which the Award pertains, and such other provisions as the Committee
determines.

     9.5  Form and Timing of Payment of Performance Shares. Payment of earned
Performance Shares will be made as soon as practicable after the close of the
applicable Performance Period, in a manner determined by the Committee in its
sole discretion and set forth in an Award Agreement. The Committee will pay
earned Performance Shares in the form of cash, in Shares, or in a combination of
cash and Shares, as specified in the Award Agreement. Performance Shares may be
paid subject to any restrictions deemed appropriate by the Committee.

                                      -12-
<PAGE>

     9.6     Termination of Service Due to Death or Disability. Unless
determined otherwise by the Committee and set forth in the Participant's Award
Agreement, if a Participant's Service is terminated by reason of death or
Disability during a Performance Period, the Participant will receive a prorated
payout of the Performance Shares, as specified by the Committee in its
discretion in the Award Agreement. Payment of earned Performance Shares will be
made at a time specified by the Committee in its sole discretion and set forth
in the Participant's Award Agreement.

     9.7     Termination of Service for Other Reasons. If a Participant's
Service terminates during a Performance Period for any reason other than death
or Disability, the Participant will forfeit all Performance Shares to the
Company, unless the Participant's Award Agreement provides otherwise.

     9.8     Nontransferability. Except as otherwise provided in a Participant's
Award Agreement, Performance Shares may not be sold, transferred, pledged,
assigned or otherwise alienated or hypothecated, other than by will or by the
laws of descent and distribution. Further, except as otherwise provided in a
Participant's Award Agreement, a Participant's rights under the Plan will be
exercisable during the Participant's lifetime only by the Participant or
Participant's guardian or legal representative. The Committee may, in its
discretion, require a Participant's guardian or legal representative to supply
it with evidence the Committee deems necessary to establish the authority of the
guardian or legal representative to act on behalf of the Participant.

Article 10.  Breach of Restrictive Covenants
             -------------------------------

     An Award Agreement may provide that, notwithstanding any other provision of
this Plan to the contrary, if the Participant breaches the non-compete, non-
solicitation or non-disclosure provisions of the Award Agreement, the
Participant will forfeit:

             (a)  any and all Awards granted or transferred to him or her under
     the Plan, including Awards that have become vested and exercisable;

             (b)  any and all Shares awarded or transferred to him or her under
     the Plan, including Awards as to which all other applicable restrictions
     have lapsed; and/or

             (c)  the profit the Participant has realized on the exercise of any
     Options, which is the difference between the Exercise Price of the Options
     and the applicable Fair Market Value of the Shares (the Participant may be
     required to repay such difference to the Company).

Article 11.  Deferrals
             ---------

     The Committee may permit or require a Participant to defer receipt of cash
or Shares that would otherwise be due to him or her by virtue of an Option or
SAR exercise, the lapse or waiver of restrictions on Restricted Stock, or the
satisfaction of any requirements or objectives with respect to Performance
Shares. If any such deferral election is permitted or required, the Committee
will, in its sole discretion, establish rules and procedures for such deferrals.
Notwithstanding the foregoing, the Committee in its sole discretion may defer
payment of cash

                                      -13-
<PAGE>

or the delivery of Shares that would otherwise be due to a Participant under the
Plan if payment or delivery would result in the Company's or any Company
Parties' being unable to deduct compensation under Code Section 162(m). Deferral
of payment or delivery by the Committee may continue until the Company Party is
able to deduct the payment or delivery under the Code.

Article 12.  Rights of Participants
             ----------------------

     Nothing in the Plan will interfere with or limit in any way the right of
any of the Company Parties to terminate any Participant's Service at any time,
or confer upon any Participant any right to continue in the Service of any of
the Company Parties.

Article 13.  Amendment, Modification and Termination
             ---------------------------------------

     13.1    Amendment, Modification and Termination. Subject to Section 13.2,
the Board may at any time and from time to time, alter, amend, modify or
terminate the Plan in whole or in part. Subject to the terms and conditions of
the Plan, the Committee may modify, extend or renew outstanding Awards under the
Plan, or accept the surrender of outstanding Awards (to the extent not already
exercised) and grant new Awards in substitution of them (to the extent not
already exercised). The Committee will not, however, modify any outstanding
Incentive Stock Option so as to specify a lower Exercise Price. Notwithstanding
the foregoing, no modification of an Award will, without the prior written
consent of the Participant, materially impair any rights or obligations under
any Award already granted under the Plan.

     13.2    Adjustment of Awards Upon the Occurrence of Certain Unusual or
Nonrecurring Events. In recognition of unusual or nonrecurring events
(including, without limitation, the events described in Section 4.3) affecting
the Company or its financial statements, or in recognition of changes in
applicable laws, regulations, or accounting principles, and, whenever the
Committee determines that adjustments are appropriate in order to prevent
dilution or enlargement of the benefits or potential benefits intended to be
made available under the Plan, the Committee may, using reasonable care, make
adjustments in the terms and conditions of, and the criteria included in,
Awards. In case of an Award designed to qualify for the Performance-Based
Exception, the Committee will take care not to make an adjustment that would
disqualify the Award.

     13.3    Compliance with Code Section 162(m). Awards will comply with the
requirements of Code Section 162(m), unless the Committee determines that such
compliance is not desired with respect to an Award available for grant under the
Plan. In addition, if changes are made to Code Section 162(m) to permit greater
flexibility as to any Award available under the Plan, the Committee may, subject
to this Article 15, make any adjustments it deems appropriate.

Article 14.  Withholding
             -----------

     14.1    Tax Withholding. The Company will have the power and the right to
deduct or withhold, or require a Participant to remit to the Company, an amount
(either in cash or Shares) sufficient to satisfy federal, state, and local
taxes, domestic or foreign, required by law or regulation to be withheld with
respect to any taxable event arising under this Plan. Each Award

                                      -14-
<PAGE>

Agreement will specify whether reload options will be granted in connection with
payment of tax withholding by tendering Shares owned by the Participant.

     14.2    Share Withholding. With respect to withholding required upon the
exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock,
or upon any other taxable event arising as a result of Awards granted hereunder,
the Company may satisfy the minimum withholding requirement for supplemental
wages, in whole or in part, by withholding Shares having a Fair Market Value
(determined on the date the Participant recognizes taxable income on the Award)
equal to the withholding tax required to be collected on the transaction. The
Participant may elect, subject to the approval of the Committee, to deliver the
necessary funds to satisfy the withholding obligation to the Company, in which
case there will be no reduction in the Shares otherwise distributable to the
Participant.

Article 15.  Successors
             ----------

     All obligations of the Company under the Plan or any Award Agreement will
be binding on any successor to the Company, whether the existence of the
successor results from a direct or indirect purchase of all or substantially all
of the Company's Shares, or a merger, consolidation, or otherwise.

Article 16.  Legal Construction
             ------------------

     16.1    Number. Except where otherwise indicated by the context, any plural
term used in this Plan includes the singular and a singular term includes the
plural.

     16.2    Severability. If any provision of the Plan is held illegal or
invalid for any reason, the illegality or invalidity will not affect the
remaining parts of the Plan, and the Plan will be construed and enforced as if
the illegal or invalid provision had not been included.

     16.3    Requirements of Law. The granting of Awards and the issuance of
Share and/or cash payouts under the Plan will be subject to all applicable laws,
rules, and regulations, and to any approvals by governmental agencies or
national securities exchanges as may be required.

     16.4    Securities Law Compliance. As to any individual who is, on the
relevant date, an officer, director or ten percent beneficial owner of any class
of the Company's equity securities that is registered pursuant to Section 12 of
the Exchange Act, all as defined under Section 16 of the Exchange Act,
transactions under this Plan are intended to comply with all applicable
conditions of Rule 16b-3 under the Exchange Act, or any successor rule. To the
extent any provision of the Plan or action by the Committee fails to so comply,
it will be deemed null and void, to the extent permitted by law and deemed
advisable by the Committee.

     16.5    Awards to Foreign Nationals and Employees Outside the United
States. To the extent the Committee deems it necessary, appropriate or desirable
to comply with foreign law of practice and to further the purposes of this Plan,
the Committee may, without amending the Plan, (i) establish rules applicable to
Awards granted to Participants who are foreign nationals, are employed outside
the United States, or both, including rules that differ from those set forth in
this Plan, and (ii) grant Awards to such Participants in accordance with those
rules.

                                      -15-
<PAGE>

     16.6    Unfunded Status of the Plan. The Plan is intended to constitute an
"unfunded" plan for incentive and deferred compensation. With respect to any
payments or deliveries of Shares not yet made to a Participant by the Company,
the Participant's rights are no greater than those of a general creditor of the
Company. The Committee may authorize the establishment of trusts or other
arrangements to meet the obligations created under the Plan, so long as the
arrangement does not cause the Plan to lose its legal status as an unfunded
plan.

     16.7    Governing Law. To the extent not preempted by federal law, the Plan
and all agreements hereunder will be construed and enforced in accordance with
and governed by the laws of the State of Delaware, without giving effect to its
conflict of laws principles.

                                      -16-
