Westlake Group - EVA Incentive Plan - Summary

<PAGE>

                               PURPOSE & OBJECTIVE

The objective of the Westlake Group Management Incentive Plan (MIP) is to reward
executives, managers and selected key employees for their contributions toward
building the growth and adding to the value of the company on behalf of the
shareholders and investors. The plan is designed to provide these employees with
a sense of ownership and opportunity to personally benefit from the increase in
value of the company, thus, aiding in attracting and retaining key employees.

                           HOW BONUSES ARE CALCULATED

TARGET BONUS PERCENTAGE: A bonus target expressed as a percentage of base pay.
This is the (X) factor applied to the Bonus Multiple earned to determine the
final payment. Participants will be advised of their Target Bonus Percentage by
their respective Vice President/Department Head.

EVA TARGET OR EXPECTED IMPROVEMENT (EI): An EVA target will be established for
each EVA Center at the start of each year. The EVA target is equal to the
Expected Improvement (EI) in EVA relative to the previous year's EVA that is
required to achieve a bonus payout equal to a multiple of 1X. The formula for
Expected Improvement (EI) is:

                          Olefins, Vinyls & Corporate:

              EI = BEGINNING CAPITAL * 0.6% - LAST YEAR EVA * 14.7%

                              Fabricated Products:

                           EI = - LAST YEAR EVA *10.8%

                    The EVA Target for each successive period
                   is calculated using the following formula:

                         EVA TARGET = EI + LAST YEAR EVA

                                                                               2

         BONUS MULTIPLE: Bonus Multiple is the factor applied to the Target
Bonus % to determine the Declared Bonus for the period. This is calculated by
dividing the "Excess Improvement" (Actual EVA Improvement - Target EVA
Improvement) by the plan Interval and adding one (one is the target or "1X"
performance).

INTERVAL: The interval is the amount of EVA improvement over the target needed
in order to increase the multiple to 2X, or the amount of EVA decline below the
target that produces a 0X. The intervals for the various EVA Centers is
summarized below:
Note:  The interval for WCC for the 2001 Plan Year only was amended to $40mm.

         o   WCC (Consolidated):   $35mm

         o   Olefins:              $30mm

         o   Vinyls & Fab          $20mm

Thus, the formula to determine the Bonus Multiple is:

                 (ACTUAL EVA IMPROVEMENT - TARGET EVA IMPROVEMENT)

BONUS MULTIPLE = ------------------------------------------------- + 1
                                    INTERVAL

Westlake Group - EVA Incentive Plan - Summary

<PAGE>
         Meeting or Exceeding Expected Improvement in EVA is the principal
element of this Plan; however, the success of the company is also based upon
certain Non-Financial Factors and Individual Performance Factors. These factors
will be evaluated and given a weight in determining the final Declared Bonus to
be granted.

NON-FINANCIAL FACTORS (NFF'S): These are Measurable factors that help drive the
productivity and profitability of an EVA center and assist in building EVA. For
example, safety, environmental compliance, product quality. Specific measures
are determined for each factor and a method of combining these results with EVA
results is developed to determine incentive compensation payments. These NFF's
will be weighted up to 20% depending on the EVA Center.

INDIVIDUAL PERFORMANCE FACTORS (IPF'S): Factors that are specific to the
performance and contribution of an individual which are used to modify the gross
declared bonus payment to be made. This factor ranges from .80 to 1.20. For
example: 20% (Gross Declared Bonus) x .90 (IPF) = 18% (Actual Declared Bonus).
IPF measures include the following major criteria.

         o        Goal Attainment

         o        Personal Contribution & Effort

         o        Criticality

         o        Managerial Success Factors, including:

                     Value & Ethics            Communications Skills
                     Problem Solving           Leadership & Vision
                     People Management         HSE Commitment

EVA CENTERS: An EVA center is a business unit or function for which a specific
EVA target has been established and for which NFF's have been set. The current
EVA centers are outlined below. (See figure 3 for current weighting given to
each element of the Bonus Calculation.)

different EVA Centers, the following will apply:

     A participant who transfers from one EVA Center to another shall have
     his/her Bonus Reserve transferred with them. At the time of transfer, the
     award shall be prorated with respect to the year in which the transfer
     occurs.

     YEAR ONE: In the first year of the move the participant's bonus will be
     weighted 50/50 between both units. (Prorated based upon the date of the
     transfer).

     YEAR TWO: In the second year of the move, the participant's bonus will be
     weighted 75% to the new unit and 25% to the original unit.

     YEAR THREE: In the third year, the bonus will be based 100% on the new
     unit.

TAX: Bonus payments will be subject to normal payroll withholding during the
period in which the bonus is paid. Banked bonuses will not be subject to
taxation until actual cash payments are made to participants.

PLAN AMENDMENTS: The Company reserves the right at any time to amend or
terminate the Plan.

BENEFICIARIES: Each plan participant should declare a beneficiary(s) to receive
payments in the event of the death of the participant.

NO GUARANTEE: Participation in the plan provides no guarantee that a bonus will
be paid. The success of Westlake, its business units and individual employees as
measured by the EVA achievement and personal contribution shall determine the
extent to which Participants shall be entitled to receive bonuses. Participation
in the plan is not a guarantee of continued employment.

EXCLUSION CRITERIA: Participation in the plan is not a right, but a privilege
subject to annual review by the Chairman's Office.

NEGATIVE BALANCE: The entire Bonus Declared is credited to each employee's
personal bonus reserve account, with one third of the balance paid out each plan
year. Residual amounts, including negative balances, are banked forward to be
credited or debited against future bonus amounts. Negative balances shall not be
held as claims against employees who leave the company for any reason.

EXHIBIT 4.1

LAFARGE NORTH AMERICA INC.

2002 STOCK OPTION PLAN

SECTION I. PURPOSE

     The purpose of the Lafarge North America Inc. 2002 Stock Option Plan (the
“Plan”) is to encourage and enable non-employee directors of Lafarge North
America Inc. (the “Company”) and key employees of the Company and its
subsidiary corporations (“Subsidiary” or “subsidiaries”) as defined under
Section 424(f) of the Internal Revenue Code of 1986, as amended (the “Code”),
upon whose judgment, initiative and efforts the Company largely depends for the
successful conduct of its business, to remain with and devote their best
efforts to the business of the Company, thereby advancing the interests of the
Company and its stockholders. Accordingly, the Company may grant to certain
employees the option to purchase shares of the Common Stock of the Company, par
value $1.00 per share (“Stock”), and may award bonuses in the form of Stock
subject to the restrictions set forth in Section IX (“Restricted Stock”), as
hereinafter set forth. Options to purchase shares of Stock shall be granted
automatically, as hereinafter set forth, to members of the Board of Directors
of the Company who are not officers or employees of the Company or any
Subsidiary (“Nonemployee Directors”). Options granted to employees of the
Company and its Subsidiaries and options granted to Nonemployee Directors are
referred to herein as “Employee Options” and “Director Options”, respectively,
and collectively as “Options”. Options granted under the Plan shall be
nonqualified stock options which shall not be treated as incentive stock
options under Section 422 of the Code.

SECTION II. ADMINISTRATION OF THE PLAN

     The Plan shall be administered by a committee (the “Committee”) appointed
by the Board of Directors of the Company (the “Board”) and consisting of two or
more directors of the Company; provided, however, that (i) the Committee shall
be constituted in a manner that satisfies the requirements of Section 162(m) of
the Code and the rules and regulations thereunder, which Committee shall
administer the Plan with respect to “performance-based compensation” for all
employees who are reasonably expected to be “covered employees” as those terms
are defined in Section 162(m) of the Code and the rules and regulations
thereunder, and (ii) the Committee shall be constituted in a manner that
satisfies the requirements of Rule 16b-3 under Section 16(b) of the Securities
Exchange Act of 1934, as amended (the “Exchange Act”), which Committee shall
administer the Plan with respect to all persons who are subject to Section 16
of the Exchange Act in a manner that satisfies the requirements of Rule 16b-3
under Section 16(b) of the Exchange Act.

     The Committee shall have sole authority to determine the employees who are to
be granted Employee Options and stock appreciation rights or awarded Restricted
Stock from among those eligible hereunder and to establish the number of shares
of Stock to be optioned to each, the number of stock appreciation rights to be
granted to each and the number of shares to be awarded to each in the form of
Restricted Stock, after taking into consideration the position held, the duties
performed, the compensation received, the services expected to be rendered by
such employee and other relevant factors. The Committee is authorized to
interpret the Plan, and may from time to time adopt such rules and regulations,
not inconsistent with the provisions of the Plan, as it may deem advisable to
carry out the Plan; provided, however, that the Committee shall have no
authority, discretion or power to select the persons who will receive Director
Options, to set the number of shares to be covered by any Director Option, to
set the exercise price or the period within which Director Options may be
exercised or to alter any other terms or conditions specified herein, except in
connection with the administration of the Plan subject to the express
provisions hereof. A majority (but not fewer than two) of the members of the
Committee shall constitute a quorum and the acts of a majority of the members
present at any meeting at which a quorum is present, or acts approved in
writing by a majority (but not fewer than two) of the members of the Committee,
shall be deemed the acts of the Committee. All decisions made by the Committee
in selecting the employees to whom Employee Options and stock appreciation
rights shall be granted or Restricted Stock shall be awarded, in establishing
the number of shares that may be issued under each Employee Option or awarded
as Restricted Stock to employees and the terms of grants and awards under the
Plan and in construing the provisions of the Plan shall be final. No member of
the Committee shall be liable for any action taken, failure to act,
determination or interpretation made in good faith with respect to the Plan or
any Option and stock appreciation right granted or Restricted Stock awarded
under the Plan.

1

 

SECTION III. SHARES SUBJECT TO THE PLAN

     The aggregate number of shares of Stock issued under Options or awarded in
the form of Restricted Stock under this Plan shall not exceed 6,500,000 shares.
Such shares of Stock may consist of authorized but unissued shares of Stock or
previously issued shares of Stock reacquired by the Company. Any of such
shares of Stock that remain unissued and that are not subject to outstanding
Options and have not been awarded in the form of Restricted Stock at the
termination of the Plan shall cease to be subject to the Plan. Should any
Option hereunder expire or terminate prior to its exercise in full, or any
Stock previously awarded as Restricted Stock be forfeited, the shares of Stock
subject to such Option at the time of its expiration or termination and the
shares of Restricted Stock so forfeited will again be available for grant or
award under the Plan. The aggregate number of shares of Stock that may be
issued under the Plan shall be subject to adjustment as provided in Section XI
hereof. Exercise of an Option or a related stock appreciation right in any
manner shall result in a decrease in the number of shares of Stock that may
thereafter be available for purposes of the Plan by the number of shares of
Stock as to which the Option or right is exercised (whether or not, in the case
of a stock appreciation right, such number of shares is actually issued).

SECTION IV. ELIGIBILITY

     The Committee shall determine and designate, at any time or from time to
time, the key employees of the Company and the Subsidiaries to whom Employee
Options are to be granted or Restricted Stock is to be awarded, but subject to
the terms and conditions set forth below:

     (a) The Committee may authorize the grant of Employee Options and
the award of Restricted Stock only to individuals who are key employees
(including officers and directors who are also key employees) of the
Company or a Subsidiary at the time the Option is granted or the
Restricted Stock is awarded. Options may be granted or Restricted Stock
awarded to the same employee on more than one occasion.

     (b) The aggregate number of shares of Stock that may be subject to
Employee Options and stock appreciation rights granted or Restricted
Stock awarded under the Plan to any one employee during any calendar year
shall not exceed 100,000.

SECTION V. OPTION PRICE

     The Option price per share of Stock underlying each Employee Option shall
be fixed by the Committee at the time the Option is granted, but shall not be
less than 100% of the fair market value of the Stock at the time of the
granting of the Option. The Option price per share of Stock underlying each
Director Option shall be 100% of the fair market value of the Stock at the time
of the granting of the Option. For purposes of the Plan, the fair market value
of Stock on any particular date shall be the mean of the high and low sales
prices of publicly traded shares of Stock on the date in question as reported
on the Composite Transactions reporting system or, if the Stock is listed on a
U.S. national securities exchange, the last sales price reported on such
exchange on that date, provided, that if there are no sales of Stock on the
date in question, then such determination shall be made on the basis of sales
of Stock on the last preceding date for which such sales are reported.

SECTION VI. OPTION TERM

     The expiration date of an Employee Option shall be determined by the
Committee at the time of grant, but shall in no event be later than ten years
from the date of grant. The expiration date of each Director Option shall be
the date that is ten years from the date of grant.

2

 

SECTION VII. OPTION AGREEMENTS

     Each Option shall be evidenced by an option agreement (“Option Agreement”)
and shall contain such terms and conditions not inconsistent with the
provisions of the Plan as may be approved by the Committee. The terms and
conditions of the respective Option Agreements evidencing Employee Options need
not be identical and may be amended by the Committee from time to time, subject
to the provisions of the Plan; provided, however, that in no event shall an
Option Agreement be amended after the date of grant of the Option in a manner
that will reduce the Option price. The terms and conditions of the respective
Option Agreements evidencing Director Options shall be identical, to the extent
practicable, and may be amended by the Committee as necessary to ensure
compliance with the provisions of the Plan. Payment of the purchase price of
any Option exercised shall be made to the Company either (i) in cash (including
check, bank draft or money order) or (ii) by delivering shares of Stock already
owned by the optionee (or by his or her permitted transferees as contemplated
by Section VIII(d) or X(e) hereof) and which have been owned, free of any
restrictions, for at least six months, duly endorsed for transfer or (iii) a
combination of such Stock and cash. The fair market value of any Stock so
delivered shall be determined on the same basis as provided in Section V
hereof. An Option Agreement evidencing an Employee Option may provide as
contemplated by Section VIII(c) hereof.

SECTION VIII. EXERCISE OF EMPLOYEE OPTIONS

     (a) Each Employee Option granted under the Plan shall be exercisable
during such period commencing on or after the expiration of one year from
the date of the grant of such Option as the Committee shall determine;
provided, however, that the otherwise unexpired portion of any Employee
Option shall expire and become null and void no later than upon the first
to occur of (i) the expiration of ten years from the date such Option was
granted, (ii) the expiration of three months from the date of the
termination of the optionee’s employment with the Company or any parent
or subsidiary corporation of the Company (an “Affiliate”) within the
meaning of Section 424(e) and (f) of the Code for any reason other than
death, disability or retirement under the normal or early retirement
provisions of a pension or retirement plan maintained by the Company or
an Affiliate, or (iii) the expiration of four years from the date of the
termination of the optionee’s employment with the Company or an Affiliate
by reason of death, disability or retirement under the normal or early
retirement provisions of a pension or retirement plan maintained by the
Company or an Affiliate. Following termination of an optionee’s
employment, his or her Employee Options shall be exercisable during the
applicable period described in clause (ii) or (iii) of the preceding
sentence to the extent such Options were exercisable on the date of
termination, except that if an optionee has completed at least ten years
of continuous service as an employee of the Company and its Affiliates at
the time of termination of the optionee’s employment with the Company or
any Affiliate by reason of death, disability or retirement as described
in clause (iii), all Employee Options held by such optionee (or his or
her permitted transferees as contemplated by Section VIII(d) hereof)
shall continue to vest during the four-year period described in clause
(iii), in accordance with their terms, unless thereafter terminated in
accordance with any other provision of the Plan or the applicable Option
Agreement; provided, however, that if the optionee engages in any
Competitive Activity during such four-year period, such Employee Options
shall cease vesting on the date immediately preceding the commencement of
the Competitive Activity. Transfer of employment without interruption of
service between or among the Company and its Affiliates shall not be
considered to be a termination of employment for purposes of the Plan.
The foregoing provisions of this subsection (a) and any other provision
of the Plan to the contrary notwithstanding, the otherwise unexpired
portion of any Employee Option granted hereunder shall expire and become
null and void immediately upon an optionee’s termination of employment
with the Company or an Affiliate by reason of such optionee’s fraud,
dishonesty or performance of other acts detrimental to the Company or an
Affiliate. Nothing in this paragraph or in any other provision of the
Plan shall cause the period during which an Employee Option may be
exercised to be extended beyond the period specified in clause (i) or in
clause (ii) or (iii), as applicable, of the first sentence of this
paragraph.

     For purposes of this Section VIII(a), “Competitive Activity” means
(i) engaging directly or indirectly, alone or as a shareholder, partner,
director, officer, member, manager, employee of

3

 

or consultant to any other business organization, in any business
activities in North America that relate to the manufacture, sale,
marketing or distribution of cement, ready-mixed concrete, other concrete
products, asphalt, construction materials, aggregates, gypsum wallboard
or related products or any other products that may be manufactured, sold,
marketed or distributed by the Company or its Affiliates at the time of
termination of the optionee’s employment (the “Designated Industry”);
(ii) directly or indirectly soliciting or encouraging any customer of the
Company or its Affiliates to divert its business to any competitor of the
Company; (iii) directly or indirectly soliciting or encouraging any
director, officer, employee of or consultant to the Company or its
Affiliates to end his or her relationship with the Company or an
Affiliate or to commence any such relationship with any competitor of the
Company; or (iv) divulging to any person or entity other than the Company
and its Affiliates any proprietary or confidential information of the
Company and its Affiliates without the prior written permission of the
Company. “Competitive Activity” shall not include the ownership of less
than five percent of the common stock of a publicly traded corporation
conducting business activities in the Designated Industry.

     (b) Each Employee Option granted hereunder shall be exercisable in
full or in such annual installments as may be determined by the Committee
at the time of the grant; provided, however, that the Committee in its
discretion may subsequently accelerate the exercise date of an Employee
Option. The right to purchase shares of Stock shall be cumulative so
that when the right to purchase any shares of Stock has accrued, such
shares or any part thereof may be purchased at any time thereafter until
the expiration or termination of the Employee Option.

     (c) If the Committee grants stock appreciation rights in connection
with an Employee Option, such rights shall be subject to the same terms
and conditions as the related Option and shall be exercisable only to the
extent the Option is exercisable. Stock appreciation rights shall be
granted only in connection with an Employee Option. A right shall
entitle the optionee to surrender to the Committee the related
unexercised Option, or any portion thereof, and to receive from the
Company in exchange therefor cash, shares of Stock, or a combination of
cash and Stock, having an aggregate value equal to (i) the excess of the
fair market value of one share of Stock over the Option price, times (ii)
the number of shares of Stock called for by the Option, or portion
thereof, which is surrendered. The number of shares of Stock which may
be received pursuant to the exercise of a right may not exceed the number
of shares of Stock called for by the Option, or portion thereof, which is
surrendered. No fractional shares of Stock will be issued. The
Committee shall have the right to determine whether the Company’s
obligation shall be paid in cash, shares of Stock, or a combination of
cash and Stock. The Committee may establish a maximum appreciation value
which would be awardable under any granted right or rights.

     (d) Except as provided in this subsection (d), no Employee Option
granted under the Plan shall be transferable otherwise than by will or
the laws of descent and distribution and shall be exercisable, during the
lifetime of the optionee, only by the optionee. Employee Options granted
hereunder may be transferred by the optionee thereof to one or more
permitted transferees; provided that (i) there may be no consideration
for such transfer (other than interests in a family trust, partnership or
limited liability company as contemplated in clauses (ii) and (iii) of
the definition of “permitted transferees” below), (ii) the optionee (or
such optionee’s estate or representative) shall remain obligated to
satisfy all income or other tax withholding obligations associated with
the exercise of the Options, (iii) the optionee shall notify the Company
in writing that such transfer has occurred, the identity and address of
the permitted transferee and the relationship of the permitted transferee
and (iv) such transfer shall be effected pursuant to transfer documents
in a form approved from time to time by the Committee. To the extent any
Employee Options transferred pursuant to this Section VIII(d) are not
fully exercisable as of the date of transfer thereof, the optionee shall
specify in the transfer document whether and to what extent the
transferred Options (if less than all of the Options subject to the
applicable Option Agreement) are exercisable, subject to the limitations
on exercisability contained in the applicable Option Agreement.
Furthermore, to the extent the optionee transfers Employee Options that
are not exercisable as of the date of transfer and such Options are less
than all of the Options subject to the applicable Option Agreement, the
optionee shall specify in the transfer documents, subject to the
limitations on exercisability contained in the applicable Option
Agreement, when the

4

 

transferred Options become exercisable under the applicable Option
Agreement subsequent to such transfer. A permitted transferee may not
further assign or transfer the transferred Employee Options otherwise
than by will or the laws of descent and distribution. Following any
permitted transfer, any such Options shall continue to be subject to the
same terms and conditions as were applicable immediately prior to
transfer. The events of termination of relationship in Section VIII(a)
hereof shall continue to be applied with respect to the optionee,
following which the Employee Options shall be exercisable by the
transferee only to the extent, and for the periods specified in Section
VIII(a). The term “permitted transferees” shall mean one or more of the
following: (i) any member of the optionee’s immediate family; (ii) a
trust established primarily for the benefit of one or more members of
such immediate family; (iii) a partnership or limited liability company
in which such immediate family members are the only partners or members;
or (iv) any other entity that is approved by the Committee in its
discretion and that is established by the optionee or the optionee’s
immediate family members for estate planning purposes. The term
“immediate family” is defined for such purpose as spouses, parents,
children, stepchildren and grandchildren, including relationships arising
from adoption. The provisions of this subsection (d) shall also apply to
any stock appreciation rights granted in connection with Employee
Options.

     (e) Nothing in this Section shall operate to extend the period of
exercise of an Employee Option beyond the expiration date specified in
the Option Agreement.

SECTION IX. RESTRICTED STOCK

     The Committee may from time to time, in its sole discretion, award bonuses
in the form of Restricted Stock to persons eligible to receive awards of
Restricted Stock under Section IV. All Restricted Stock awarded under the Plan
shall be subject to such restrictions, terms and conditions, if any, as may be
determined by the Committee, except that all awards of Restricted Stock under
the Plan that are performance based must be restricted for at least one year
from the date of award and all awards of Restricted Stock under the Plan that
are not performance based must be restricted for at least three years from the
date of award. The Committee may in its sole discretion remove, modify or
accelerate the release of restrictions on any Restricted Stock in the event of
death or disability of the recipient of such Restricted Stock. Nonemployee
Directors shall not be eligible to receive awards of Restricted Stock under
this Plan.

     Any certificate or certificates representing shares of Restricted Stock
shall bear a stamped or printed notice on the face thereof to the effect that
such shares have been awarded pursuant to the terms of the Plan and may not be
sold, pledged, transferred, assigned or otherwise encumbered in any manner
except as set forth in the terms of such award. If the Committee so
determines, the certificates representing Restricted Stock shall be deposited
by the recipient with the Company or an escrow agent designated by the Company
until the restrictions thereon have lapsed or have been removed in accordance
with the provisions of this Section. Upon the lapse of the restrictions or
removal thereof by the Committee, new unrestricted certificates for the number
of shares on which the restrictions have lapsed or been removed shall, upon
request by the recipient of the Restricted Stock, be issued in exchange for
such restricted certificates.

SECTION X. DIRECTOR OPTIONS

     In addition to the other provisions of this Plan relating to Director
Options, the following provisions shall govern the grant and exercise of
Director Options under the Plan:

     (a) Director Options shall be granted to Nonemployee Directors in
accordance with the following; provided, however, that a Nonemployee
Director may decline to accept any Director Option by giving notice to
such effect to the Committee or by refusing to execute an Option
Agreement relating to the Option:

     (1) a Director Option representing the right to purchase
5,000 shares of Stock shall be granted automatically to each new
Nonemployee Director on and effective as of the date on which such
person is first elected or appointed to serve as a Nonemployee
Director, provided, that if a Nonemployee Director who has
received a

5

 

Director Option under this subsection (a)(1) ceases serving
as a director and is subsequently elected or appointed as a
Nonemployee Director, he or she shall not receive a second
Director Option pursuant to this subsection (a)(1); and

     (2) a Director Option representing the right to purchase
1,000 shares of Stock shall be granted automatically on and
effective as of the date of the first meeting of the Committee in
each year, beginning with the year 2003, to each person who is a
Nonemployee Director of the Company on such date (including
persons who have previously received Director Options under the
Plan);

provided, however, that if as of the effective date of any grant of
Director Options there are not sufficient shares available under the Plan
to allow for the grant to each Nonemployee Director of a Director Option
for the number of shares provided herein, then each Nonemployee Director
shall be granted an option for a pro rata portion of the total number of
shares then available (disregarding fractional shares). Any provision of
this Plan to the contrary notwithstanding,, in no event shall a
Nonemployee Director receive a Director Option under (1) or (2) above if
such Nonemployee Director receives on the same date an option to purchase
shares of Stock under any other option plan of the Company or an
Affiliate.

     (b) Each Director Option shall vest in accordance with the following:

     (1) one-fourth of the shares subject to the Director Option
shall be vested at the date of grant of the Director Option for
each continuous full year of service by the grantee on the Board
prior to such date of grant; and

     (2) if the Director Option is not fully vested on the date of
grant, one-fourth of the Shares subject thereto shall vest on each
anniversary of the date of commencement of the grantee’s service
on the Board until the Director Option is fully vested, provided,
however, that no portion of any Director Option shall vest after
the Nonemployee Director’s service on the Board has terminated for
any reason.

     (c) Each Director Option shall be exercisable in whole at any time
and in part from time to time to the extent such Director Option has
vested in accordance with the foregoing; provided, however, that the
otherwise unexpired portion of any Director Option shall expire and
become null and void no later than upon the first to occur of (i) the
expiration of ten years from the date such option was granted, (ii) the
expiration of three months from the date of the termination of the
Nonemployee Director’s service on the Board for any reason other than
death or retirement under the normal or early retirement provisions of
any retirement plan maintained by the Company for Nonemployee Directors
or (iii) the expiration of four years from the date of the termination of
the Nonemployee Director’s service on the Board by reason of death or
retirement under the normal or early retirement provisions of any
retirement plan maintained by the Company for Nonemployee Directors.
Following termination of a Nonemployee Director’s service on the Board,
his or her Director Options shall be exercisable during the applicable
period described in clause (ii) or (iii) of the preceding sentence to the
extent such Options were exercisable on the date of termination. The
foregoing provisions of this subsection (c) and any other provision of
this Plan to the contrary notwithstanding, the otherwise unexpired
portion of any Director Option granted hereunder shall expire and become
null and void immediately upon termination of the Nonemployee Director’s
service on the Board if such termination occurs by reason of such
Nonemployee Director’s (i) fraud or intentional misrepresentation or (ii)
embezzlement, misappropriation or conversion of assets or opportunities
of the Company or any Affiliate. The right to purchase shares of Stock
shall be cumulative so that when the right to purchase any shares of
Stock has accrued, such shares or any part thereof may be purchased at
any time thereafter until the expiration or termination of the Director
Option. Nothing in this paragraph or in any other provision of the Plan
shall cause the period during which a Director Option may be exercised to
be extended beyond the period specified in clause (i) or in clause (ii)
or (iii), as applicable, of the first sentence of this paragraph.

6

 

     (d) Stock appreciation rights shall not be granted in connection
with Director Options.

     (e) Except as provided in this subsection (e), no Director Option
granted under the Plan shall be transferable otherwise than by will or
the laws of descent and distribution and shall be exercisable, during the
lifetime of the optionee, only by the optionee. Director Options granted
hereunder may be transferred by the optionee thereof to one or more
permitted transferees to the same extent, and subject to the same
conditions and limitations, as specified with respect to Employee Options
in Section VIII(d) hereof (except that the references therein to Section
VIII(a) shall be deemed, for purposes of this Section X(e), to be
references to Section X(c) hereof).

     (f) The aggregate number of shares of Stock that may be issued under
Director Options granted under the Plan to any one Nonemployee Director
shall not exceed the lesser of 20,000 shares or 5% of the outstanding
shares of Stock.

     (g) Nothing in this Section shall operate to extend the period of
exercise of a Director Option beyond the expiration date specified in the
Option Agreement.

SECTION XI. ADJUSTMENTS UPON RECAPITALIZATION OR REORGANIZATION

     In the event the Company shall effect a split of the Stock or dividend
payable in Stock (other than pursuant to the Company’s Optional Stock Dividend
Plan), or in the event the outstanding Stock shall be combined into a smaller
number of shares, the maximum number of shares of Stock as to which Options may
be granted and Restricted Stock may be awarded under the Plan shall be
increased or decreased proportionately. In the event that before delivery by
the Company of all of the shares of Stock in respect of which any Option or
related stock appreciation right has been granted under the Plan, the Company
shall have effected such a split, dividend or combination, the shares of Stock
still subject to the Option or stock appreciation right shall be increased or
decreased proportionately and the purchase price per share of Stock shall be
decreased or increased proportionately so that the aggregate purchase price for
all of the then optioned shares of Stock shall remain the same as immediately
prior to such split, dividend or combination.

     In the event of a reclassification of the Stock not covered by the
foregoing, or in the event of a liquidation or reorganization, including a
merger, consolidation or sale of assets, the Board shall make such adjustments,
if any, as it may deem appropriate in the number and kind of shares for which
Options, stock appreciation rights or Restricted Stock may be granted or
awarded under the Plan and, with respect to outstanding Options and stock
appreciation rights, in the number, purchase price and kind of shares covered
thereby. The provisions of this Section shall only be applicable if, and only
to the extent that, the application thereof does not conflict with any valid
governmental statute, regulation or rule.

SECTION XII. CONTINUANCE OF EMPLOYMENT OR BOARD MEMBERSHIP

     Neither the Plan nor any agreement relating to any Option, stock
appreciation right or award of Restricted Stock shall impose any obligation on
the Company or an Affiliate to continue to employ any employee or to permit any
Nonemployee Director to continue as a director of the Company.

SECTION XIII. WITHHOLDING

     The Company shall have the right to withhold taxes, as required by law,
from any transfer of cash or Stock to an employee under the Plan or to collect
from the person legally responsible therefor, as a condition of any transfer of
cash or Stock to an employee or his or her permitted transferees under the
Plan, any taxes required by law to be withheld.

     (a) Subject to the provisions of paragraphs (b) and (c) of this
Section, at any time when an employee is required to pay to the Company
an amount required to be withheld under applicable tax laws in connection
with an issuance of Stock upon exercise of an Employee Option

7

 

or stock appreciation right, the employee may satisfy this
obligation in whole or in part by electing (the “Election”) to have the
Company withhold from the issuance shares of Stock having a fair market
value equal to the amount required to be withheld; provided, however,
that such an Election shall not be permitted in connection with any
exercise of an Option or stock appreciation right by a transferee
thereof. The value of the shares of Stock to be withheld shall be based
on the fair market value of such shares as of the date on which shares of
Stock are issued to the employee pursuant to exercise of the Option or
stock appreciation right (the “Tax Date”). The employee must pay to the
Company any difference between the amount required to be withheld by the
Company and the value of the shares of Stock so withheld. Any shares of
Stock withheld shall not thereafter be available to be subject to an
Option granted under the Plan.

     (b) Each Election must be made prior to the Tax Date. The Committee
may disapprove of any Election, may suspend or terminate the right to
make Elections and may provide with respect to any Employee Option or
stock appreciation right that the right to make Elections shall not apply
to such Option or stock appreciation right. An Election is irrevocable.

     (c) If an employee is an officer or director of the Company within
the meaning of Section 16 of the Securities Exchange Act of 1934 (the
“1934 Act”) and the rules and regulations promulgated thereunder, then an
Election shall be valid only if expressly approved by the Committee prior

SECTION XIV. LEGAL RESTRICTIONS

     Nothing herein or in any Option Agreement shall require the Company to
sell or issue any Stock pursuant to an Option that has been transferred as
contemplated by Section VIII(d) or X(e) if such sale or issuance would, in the
opinion of counsel for the Company, constitute a violation of the Securities
Act of 1933, as amended (the “Securities Act”), or any similar or succeeding
statute or statutes, as then in effect. At the time of any grant or exercise
of any Options, or sale or issuance of Stock pursuant thereto, the Company may,
as a condition precedent to the sale or issuance of such Stock, require from
the holder of the Options (or in the event of such holder’s death, his or her
representatives, legatees or distributees) such written representations, if
any, concerning his or her intentions with regard to the retention or
disposition of the Stock being acquired, and such written covenants and
agreements, if any, as to the manner of disposal of such Stock as, in the
opinion of counsel to the Company, may be necessary to ensure that any
disposition by such holder (or his or her legal representatives, legatees or
distributees) will not involve a violation of the Securities Act, or any
similar or succeeding statute or statutes, or any other applicable federal or
state statute, rule or regulation, as then in effect. Certificates for Stock,
when issued, shall have appropriate legends, or statements of other applicable
restrictions, endorsed thereon, and may or may not be immediately transferable.

SECTION XV. AMENDMENT OR TERMINATION OF THE PLAN

     The Board in its discretion may terminate the Plan at any time with
respect to any shares of Stock for which Options have not theretofore been
granted or that have not been awarded as Restricted Stock. The Board shall
have the right to alter or amend the Plan or any part thereof from time to
time; provided, that no such change may be made which would impair the rights
of the optionee under any outstanding Option or the recipient of Restricted
Stock without the consent of such optionee or recipient; and provided further,
that the Board may not, without the approval of the stockholders of the
Company, make any alteration or amendment that would materially increase the
benefits accruing to participants under the Plan, increase the aggregate number
of shares of Stock that may be issued pursuant to the provisions of the Plan,
or materially modify the requirements for participation in the Plan or that is
otherwise required by law or regulations to be approved by the stockholders.

SECTION XVI. EFFECTIVENESS AND EXPIRATION OF THE PLAN

     If adopted by the Board and approved by the vote of the holders of a majority
of the stock of the Company present or represented and voting on the matter at
a meeting of stockholders duly called and held for such purpose, or at an
annual meeting thereof, the notice of which has specified that action is to be
taken on the Plan, and the Committee shall have been advised by legal counsel
for the Company that in the opinion of such counsel all applicable requirements
of law precedent to its becoming effective have been fully met, then the Plan
shall become effective as of May 15, 2002, or as soon thereafter as the
aforesaid requirements have been met. The Plan shall expire five years after
the effective date of the Plan. If the stockholders of the Company fail so to
approve the Plan, the Plan shall thereupon terminate and all Options previously
granted and all awards of Restricted Stock under the Plan shall become void and
of no effect. With respect to persons subject to Section 16 of the 1934 Act,
transactions under the Plan are intended to comply with applicable conditions
of Rule 16b-3 or its successors under the 1934 Act. To the extent any
provisions of the Plan or action by the Committee fails to so comply, it shall
be deemed null and void, to the extent permitted by law and deemed advisable by
the Committee or by the Board.
