for convenience and if there is any conflict between such headings and the text
of the Plan, the text shall control.

                    ARTICLE 3: ELIGIBILITY AND PARTICIPATION

3.1 ELIGIBILITY. All Eligible Employees shall be eligible to participate in the
Plan for an Option Period, provided that the Eligible Employee's employment with
an Employer continues uninterrupted throughout the Option Period. A transfer
between or among Employers shall not be treated as an interruption of the
Eligible Employee's employment.

3.2 PARTICIPATION.

         (a) ELECTION TO PARTICIPATE. An Eligible Employee shall become a
         Participant after satisfying the eligibility requirements and
         delivering to the Plan Administrator during the enrollment period
         established by the Plan Administrator an enrollment form that (1)
         indicates the Eligible Employee's election to participate in the Plan
         as of the next following Date of Grant; (2) authorizes the payroll
         deduction and states the amount to be deducted regularly from the
         Participant's Eligible Compensation and to be accrued under the Plan
         for his benefit; and (3) authorizes the purchase of the Common Stock at
         the end of the Option Period. The effective date of a Participant's
         participation shall be the Date of Grant following the Plan
         Administrator's receipt of the Participant's authorization. The
         procedure established by the Plan Administrator for an Eligible
         Employee to enroll in the Plan may be through any written form or any
         telephonic, electronic mail, intranet, internet or any other electronic
         process established by the Plan Administrator from time to time.

         (b) CONTINUING ELECTION. A Participant's election to participate in the
         Plan with respect to an Option Period shall continue for each
         successive Option Period at the same payroll deduction percentage as in
         effect at the termination of the prior Option Period unless the
         Participant amends or cancels his participation pursuant to Section
         3.2(d).

         (c) PAYROLL DEDUCTIONS. Each Participant will designate in his
         participation election the stated amount to be deducted from his
         Eligible Compensation on each payday. A Participant may elect to have
         deducted from 1% to 10% of his Eligible Compensation, or such other
         percentages as the Committee may from time to time determine. A
         Participant's percentage deduction election must be in whole
         percentages, and a Participant's payroll deductions for the entire
         Option Period are based on his Eligible Compensation at the beginning
         of the Option Period. The stated amount may not be less than a sum that
         will result in the payment into the Plan of at least $5.00 each payday.
         The stated amount may not exceed either of (1) 10% of the amount of
         Eligible Compensation (or such other maximum percentage as determined
         by the Committee), or (2) an amount which will result in noncompliance
         with the $25,000 statutory limitation described in Section 4.2.

                  Participant payroll deductions are maintained by the Company
         as an accrual for the benefit of the Participant until the Date of
         Exercise.

         (d) CHANGES IN PAYROLL DEDUCTIONS. By delivering to the Plan
         Administrator a new written payroll deduction authorization form, a
         Participant may amend the stated amount of his payroll deduction to
         reduce the rate of his payroll deductions at any time during an Option
         Period. A Participant's payroll deduction designation rate may not be
         increased during an Option Period. The new payroll deduction rate will
         become

                                       3
<PAGE>


         effective for the next payroll period, provided that the next payroll
         period commences more than 15 days after receipt of the new
         authorization form. Any change to the rate of payroll deduction will
         continue for the remainder of the Option Period. Changes in the rate of
         payroll deductions are limited to one change during any Option Period.

         (e) LEAVES OF ABSENCE. During leaves of absence approved by the Plan
         Administrator and in compliance with the requirements of Treasury
         Regulation section 1.421-7(h)(2), a Participant may continue
         participation in the Plan at the stated amount in his payroll deduction
         election by making cash payments to the Company on his normal paydays
         equal to any reduction in his payroll deductions caused by his leave.

         (f) RE-ADMISSION TO PARTICIPATE AFTER TERMINATION OF PARTICIPATION. If
         a Participant's participation in the Plan is terminated due to his
         withdrawal from the Plan in accordance with the provisions of Section
         3.3(a), the Participant shall be eligible to participate again in the
         Plan upon the expiration of the Option Period during which such
         Participant ceased participation and may participate in any subsequent
         Option Period by making an election to participate in accordance with
         the provisions of Section 3.2(a). If a Participant's participation in
         the Plan is terminated due to his termination of employment and he is
         subsequently re-employed by an Employer, he may participate in the Plan
         upon his re-employment if he satisfies the eligibility requirements of
         Section 3.1 and he elects to participate in the Plan in accordance with
         the provisions of Section 3.2(a).

3.3      TERMINATION OF PARTICIPATION.

         (a) WITHDRAWAL FROM PARTICIPATION. A Participant may withdraw
         completely from participation in the Plan at any time during an Option
         Period. To withdraw from the Plan, a Participant must deliver to the
         Plan Administrator a notice of withdrawal in a form and manner
         authorized by the Plan Administrator, and the notice of withdrawal must
         be delivered within the time period established by the Plan
         Administrator. After the Plan Administrator's receipt of the notice of
         withdrawal, the Participant's payroll deduction authorization and his
         interest in unexercised options under the Plan will terminate and the
         Participant's prior payroll deductions made under the Plan will be
         refunded to the Participant.

         (b) VOLUNTARY TERMINATION OF PARTICIPATION. A Participant may
         voluntarily terminate his participation in the Plan by lowering the
         rate of his payroll deductions to zero for the remainder of the Option
         Period, in accordance with the provisions of Section 3.2(d). A
         Participant who has decreased his rate of payroll deduction to zero
         will be deemed to continue as a Participant in the Plan until he
         withdraws from the Plan in accordance with the provisions of Section
         3.3(a) or his participation is terminated in accordance with the
         provisions of Section 3.3(c). As long as the Participant continues as a
         Participant in the Plan, the amount accrued for the Participant under
         the Plan will be applied to the purchase of Common Stock at the end of
         the Option Period.

         (c) INVOLUNTARY TERMINATION OF PARTICIPATION.

                  (1) TERMINATION OF EMPLOYMENT OTHER THAN BY RETIREMENT, DEATH
                  OR DISPOSITION OF ASSETS, ETC. If the employment of a
                  Participant terminates other than by retirement, death or as a
                  result of a disposition of assets, a division or an entity or
                  as a result of a plant closing, or if he is no longer eligible
                  to participate in the Plan, his participation in the Plan
                  shall, without any action on his part, automatically terminate
                  as of the date of the termination of his employment or the
                  date of the termination of his eligibility. The Employer will
                  refund to the Participant the amount of the Participant's
                  prior payroll deductions made under the Plan, and his interest
                  in unexercised Options under the Plan shall terminate. A
                  termination of employment does not include a transfer of
                  employment among Employers or a transfer of employment to a
                  venture or entity in which the Company or an Affiliate has an
                  equity interest exceeding 50%.

                  (2) TERMINATION BY RETIREMENT. If a Participant is at least 55
                  years of age and has an aggregate of at least ten years of
                  service with all Employers, he may retire from the Plan. The
                  Participant may, at his election by written notice to the Plan
                  Administrator, either (A) exercise his Option as of his
                  termination date, in which event the Employer shall apply the
                  amount accrued

                                       4
<PAGE>

                  under the Plan at that time to the purchase at the Option
                  Price of shares of Common Stock, including fractions, or (B)
                  request payment of the Participant's prior payroll deductions
                  made under the Plan at that time, in which event the Employer
                  promptly shall make such payment, and thereupon the
                  Participant's interest in unexercised Options under the Plan
                  shall terminate. If the Participant elects to exercise his
                  Option, the date of his termination shall be deemed to be the
                  Date of Exercise for the purpose of computing the amount of
                  the Option Price of the Common Stock.

                  (3) TERMINATION BY DEATH. If a Participant's employment is
                  terminated by his death, any accrual under the Plan for the
                  purchase of shares of Common Stock and any shares of Common
                  Stock in the Participant's name shall be distributed to the
                  Participant's Beneficiaries.

                  (4) TERMINATION AS A RESULT OF A DISPOSITION OF ASSETS, A
                  DIVISION OR AN ENTITY OR A PLANT CLOSING. A Participant whose
                  employment with his Employer is terminated as a result of a
                  disposition of assets, a division or an entity or as a result
                  of a plant closing may, at his election by written notice to
                  the Plan Administrator, either (A) exercise his Option as of
                  his termination date, in which event the Employer shall apply
                  the amount accrued under the Plan at that time to the purchase
                  at the Option Price of shares of Common Stock, including
                  fractions, or (B) request payment of the Participant's prior
                  payroll deductions made under the Plan at that time, in which
                  event the Employer promptly shall make such payment, and
                  thereupon the Participant's interest in unexercised Options
                  under the Plan shall terminate. If the Participant elects to
                  exercise his Option, the date of his termination shall be
                  deemed to be the Date of Exercise for the purpose of computing
                  the amount of the Option Price of the Common Stock. As
                  determined by the Plan Administrator, a Participant shall be
                  deemed to have terminated his employment with all Employers
                  (A) as a result of a disposition of assets, a division or an
                  entity if such employment is terminated coincident with and as
                  a result of the disposition by the Employer, the Company or
                  their subsidiaries or Affiliates of assets, a division or any
                  other business entity (regardless of form) in connection with
                  a sale, exchange, merger or other business transaction, or (B)
                  as a result of a plant closing if such employment is
                  terminated coincident with and as a result of a significant
                  manufacturing plant closing by the Employer, but not as a
                  result of mere district changes or layoffs.

               ARTICLE 4: GRANT OF OPTIONS AND EXERCISE OF OPTIONS

4.1 GRANT OF OPTIONS. Following the effective date of the Plan and continuing
for as long as the Plan remains in force, Options will be offered under the Plan
to all Participants to purchase shares of Common Stock. Options shall be granted
on the Date of Grant and shall be exercisable on the Date of Exercise. For each
Participant, the number of shares of Common Stock, including fractions that may
be purchased under his Option shall be the lesser of (a) the aggregate payroll
deductions authorized by the Participant in accordance with Section 3.2(c) for
the Option Period divided by the Option Price or (b) the amount specified in
Section 4.2, subject to the availability of a sufficient number of shares of
Common Stock reserved for purchase under the Plan. In the event there are an
insufficient number of shares reserved for purchase under the Plan, the number
of shares purchased shall be adjusted as provided in Section 4.3.

4.2 LIMITATIONS ON THE GRANT OF OPTIONS. No Participant shall be permitted to
purchase Common Stock under the Plan or under any other employee stock purchase
plan of the Company or of any of its subsidiaries or related corporations at a
rate which exceeds $25,000 in Fair Market Value of Common Stock (determined at
the Date of Grant of the Option), and no Employee shall be granted Options for
more than 2,500 shares under the Plan at the time the Option is granted (whether
the Option Price is determined with reference to the Date of Grant or the Date
of Exercise) for each calendar year in which any such Option granted to such
Employee is outstanding at any time.

4.3 INSUFFICIENT NUMBER OF SHARES. If the number of shares of Common Stock
reserved for purchase for any Option Period is insufficient to cover the number
of shares which Participants elect to purchase during such Option Period, then
the number of shares of Common Stock which each Participant has a right to
purchase on the Date of Exercise shall be reduced to the number of shares of
Common Stock which the Plan Administrator shall determine by multiplying the
number of shares of Common Stock reserved under the Plan for such Option Period
by a fraction, the numerator of which shall be the number of shares of Common
Stock which the Participant elected to purchase during the Option Period and the
denominator of which shall be the total number of shares of Common Stock which
all Participants elected to purchase during such Option Period.

                                       5
<PAGE>


4.4 RESTRICTION UPON ASSIGNMENT. An Option shall not be transferable otherwise
than by will or the laws of descent and distribution and is exercisable during
the Participant's lifetime only by him. An Option may not be exercised to any
extent except by the Participant. The Plan Administrator and the ESPP
Administrator, if any, will not recognize, and shall be under no duty to
recognize, any assignment or purported assignment by a Participant of his Option
or of any rights under his Option.

4.5 EXERCISE OF OPTIONS; ESPP ACCOUNTS.

         (a) EXERCISE OF OPTIONS. Each Participant will be deemed,
         automatically, and without any act on his part, to have exercised his
         Option on each Date of Exercise to the extent that the amount accrued
         under the Plan is sufficient to purchase at the Option Price whole and
         fractional shares of the Common Stock, except that the number of shares
         of Common Stock purchased shall not exceed the limitations set forth in
         Section 4.2. The issuance of shares of Common Stock may be effected on
         a noncertificated basis to the extent not prohibited by applicable law
         or the applicable rules of any stock exchange.

         (b) ESPP ACCOUNTS. As soon as practicable on or before the Date of
         Exercise, the Plan Administrator shall deliver, or cause to be
         delivered, to the ESPP Administrator the information necessary to have
         the total number of shares of the Common Stock representing exercised
         Options in the aggregate (for both whole and fractional shares)
         deposited into the Participants' ESPP Accounts. The shares of Common
         Stock shall be allocated among the ESPP Accounts based on a fraction,
         the numerator of which is the amount accrued for a Participant under
         the Plan on the Date of Exercise and the denominator of which shall be
         the aggregate of the amounts accrued for all Participants under the
         Plan on the Date of Exercise. A Participant shall be free to dispose of
         the shares of Common Stock in his ESPP Account at any time, subject to
         the provisions of Sections 4.6 and 4.7 and subject to any
         administrative blackout periods.

                  Each Participant's ESPP Account shall be administered in
         accordance with procedures established from time to time by the ESPP
         Administrator.

4.6 WITHHOLDING OBLIGATIONS. At the time the Option is exercised, or at the time
some or all of the Common Stock is disposed of, a Participant shall make
adequate provision for local, state, federal and foreign withholding obligations
of his Employer, if any, that arise upon exercise of the Option or upon
disposition of the Common Stock. The Employer may withhold from the
Participant's compensation the amount necessary to meet such withholding
obligations.

4.7 NOTICE OF DISPOSITION. By becoming a Participant in the Plan, each
Participant agrees to promptly give the ESPP Administrator, or in the absence of
the ESPP Administrator, the Plan Administrator, notice of any shares of Common
Stock disposed of within the later of (a) one year from the Date of Exercise and
(b) two years from the Date of Grant with respect to such Stock, and the notice
shall include the number of shares of Common Stock disposed of and the Date of
Exercise and the Date of Grant for the Common Stock.

4.8 DISPOSITIONS IN COMPLIANCE WITH SECURITIES LAWS. By becoming a Participant
in the Plan, each Participant agrees that any dispositions of shares of Common
Stock by such Participant shall be in compliance with the provisions of federal,
state and foreign securities laws, including the provisions of Section 16(b) of
the Exchange Act.

                  ARTICLE 5: PROVISIONS RELATED TO COMMON STOCK

5.1 SHARES RESERVED. Subject to the provisions of Section 5.5 (relating to
adjustment upon changes in stock), the number of shares of Common Stock which
may be sold pursuant to Options under the Plan shall not exceed in the aggregate
14,500,000 shares, and may be unissued shares, reacquired shares or shares
bought on the market for purposes of the Plan.

                                       6
<PAGE>

5.2 NO RIGHTS OF STOCKHOLDER UNTIL EXERCISE. With respect to shares subject to
an Option, a Participant shall not be deemed to be a stockholder, and he shall
not have any of the rights or privileges of a stockholder until the exercise of
his Option. After the exercise of the Option, each Participant shall have full
stockholder rights with respect to all shares of Common Stock in his ESPP
Account, including, but not limited to, voting, dividend and liquidation rights.
The ESPP Administrator shall establish procedures to facilitate the
Participant's voting rights attributable to the Common Stock in his ESPP
Account.

5.3 REGISTRATION OF SHARES OF COMMON STOCK. Notwithstanding any other provision
of the Plan, the Company shall have no obligation to issue or deliver any shares
of Common Stock under the Plan or make any other distribution of benefits under
the Plan unless such issuance, delivery or distribution would comply with all
applicable laws (including, without limitation, the requirements of the
Securities Act), and the applicable requirements of any securities exchange or
similar entity.

         The Company shall be under no obligation to any Participant to register
for offering or resale or to qualify for exemption under the Securities Act, or
to register or qualify under state securities laws, any shares of Common Stock,
or to continue in effect any such registrations or qualifications if made. The
Company may issue certificates for shares with such legends and subject to such
restrictions on transfer and stop-transfer instructions as counsel for the
Company deems necessary or desirable for compliance by the Company with federal
and state securities laws.

         The Company shall seek to obtain from each federal, state, foreign or
other regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to issue and sell shares of Common Stock upon the
exercise of the Options. If, after commercially reasonable efforts, the Company
is unable to obtain from any such regulatory commission or agency the authority
that counsel for the Company deems necessary for the lawful issuance and sale of
shares of Common Stock in any particular jurisdiction, the Company shall be
relieved from liability to any Participant, except to return to him the
Participant's prior payroll deductions made under the Plan.

5.4 CERTIFICATES FOR SHARES. For shares of Common Stock maintained in ESPP
Accounts, the ESPP Administrator shall establish procedures, including any
applicable fees, for the delivery of a certificate representing the aggregate
number of whole shares of Common Stock in a Participant's ESPP Account. In the
absence of an ESPP Administrator, the Plan Administrator, in its sole
discretion, may determine the method for delivering certificates for shares of
Common Stock to Participants. At the time of the delivery of a certificate to
(a) a Participant, (b) a former Participant or (c) the Participant's or former
Participant's Beneficiary or Beneficiaries, any fractional share of Common Stock
in the Participant's or former Participant's ESPP Account shall be converted to
cash, which shall be distributed to the Participant, former Participant
Beneficiary or Beneficiaries.

5.5 CHANGES IN COMMON STOCK AND ADJUSTMENTS. The existence of the Plan and the
Options granted hereunder shall not limit, affect or restrict in any way the
right or power of the Board or the Company's stockholders to make or authorize
any or all adjustments, recapitalizations, reorganizations or other changes in
the capital stock of the Company or its business or any merger or consolidation
of the Company, or any issue of bonds, debentures, preferred or prior preference
stock (whether or not such issue is prior to, on a parity with or junior to the
shares of Common Stock issued under the Plan) or the dissolution or liquidation
of the Company, or any sale or transfer of all or any part of its assets or
business or any other corporate act or proceeding of any kind, whether or not of
a character similar to that of the acts or proceedings enumerated above.

         If there shall be any change in the shares of the Common Stock or the
capitalization of the Company through merger, consolidation, reorganization,
recapitalization, stock dividend, stock split, reverse stock split, split up,
spin-off, combination of shares, exchange of shares, dividend in kind or other
like change in capital structure or distribution (other than normal cash
dividends) to stockholders of the Company, the Board, in its sole discretion, to
prevent dilution or enlargement of Participants' rights under the Plan, will
take appropriate action to adjust accordingly the number of shares subject to
the Plan and the number and Option Price of shares subject to existing Options.

                        ARTICLE 6: ADMINISTRATION OF PLAN

6.1 PLAN ADMINISTRATOR. The Company shall be the "Plan Administrator."

6.2 RESIGNATION AND REMOVAL. The members of the Committee shall serve at the
pleasure of the Board; they may be officers, directors, or employees of the
Company or any other individuals. At any time during his term of office, any
member of the Committee or any individual serving as Plan Administrator may
resign by giving written notice to the Board, such resignation to become
effective upon the appointment of a substitute or, if earlier, the lapse of
thirty days after such notice is given as herein provided. At any time during
its term of office, and for any reason, any member of the Committee or any
individual serving as Plan Administrator may be removed by the Board.

6.3 RECORDS AND PROCEDURES. The Plan Administrator shall keep appropriate
records of its proceedings and the administration of the Plan and shall make
available for examination during business hours to any Participant, former
Participant or any Beneficiary of any Participant or former Participant such
records as pertain to that individual's interest in the Plan. If the Committee
is performing duties as the Plan Administrator, the Committee shall designate
the individual or individuals who shall be authorized to sign for the Plan
Administrator and, upon such designation, the signature of such individual or
individuals shall bind the Plan Administrator.

6.4 SELF-INTEREST OF PLAN ADMINISTRATOR. Neither the members of the Committee
nor any individual Plan Administrator shall have any right to vote or decide
upon any matter relating solely to himself under the Plan or to vote in any case
in which his individual right to claim any benefit under the Plan is
particularly involved. In any case in which any Committee member or individual
Plan Administrator is so disqualified to act, the other members of the Committee
shall decide the matter in which the Committee member or individual Plan
Administrator is disqualified.

6.5 COMPENSATION AND BONDING. Neither the members of the Committee nor any
individual Plan Administrator shall receive compensation with respect to their
services on the Committee or as Plan Administrator. To the extent required by
applicable law, or required by the Company, neither the members of the Committee
nor any individual Plan Administrator shall furnish bond or security for the
performance of their duties hereunder.

6.6 PLAN ADMINISTRATOR POWERS AND DUTIES. The Plan Administrator shall supervise
the administration and enforcement of the Plan according to the terms and
provisions hereof and shall have all powers necessary to accomplish these
purposes, including, but not by way of limitation, the right, power, and
authority:

         (a) to make rules, regulations, and bylaws for the administration of
         the Plan that are not inconsistent with the terms and provisions
         hereof, and to enforce the terms of the Plan and the rules and
         regulations promulgated thereunder by the Plan Administrator;

         (b) to establish procedures for the appointment of designated
         beneficiaries by Participants and former Participants;

         (c) to construe in its discretion all terms, provisions, conditions,
         and limitations of the Plan;

         (d) to correct, subject to the provisions of Section 8.2, any defect or
         to supply any omission or to reconcile any inconsistency that may
         appear in the Plan in such manner and to such extent as it shall deem
         in its discretion expedient to effectuate the purposes of the Plan;

         (e) to employ and compensate such accountants, attorneys, investment
         advisors, and other agents, employees, and independent contractors as
         the Plan Administrator may deem necessary or advisable for the proper
         and efficient administration of the Plan;

         (f) to determine in its discretion all questions relating to
         eligibility; and

         (g) to determine whether and when a Participant has incurred a
         termination of employment and the reason for such termination.

                                       8
<PAGE>


6.7 RELIANCE ON DOCUMENTS, INSTRUMENTS, ETC. The Plan Administrator may rely on
any certificate, statement or other representation made on behalf of the
Company, any Employer, any Employee, any Participant, any former Participant or
any Beneficiary, which the Plan Administrator in good faith believes to be
genuine, and on any certificate, statement, report or other representation made
to it by any agent or any attorney, accountant or other expert retained by it or
the Company in connection with the operation and administration of the Plan.

                    ARTICLE 7: EXTENSION OF PLAN TO EMPLOYERS

7.1 ADOPTION BY EMPLOYERS.

         (a) With the written approval of the Plan Administrator, any entity
         that is an Affiliate may adopt the Plan by appropriate action of its
         board of directors or noncorporate counterpart, as evidenced by a
         written instrument executed by an authorized officer of such entity or
         an executed adoption agreement (approved by the board of directors or
         noncorporate counterpart of the Affiliate), agreeing to be bound by all
         the terms, conditions and limitations of the Plan except those, if any,
         specifically described in the adoption instrument, and providing all
         information required by the Plan Administrator. The Plan Administrator
         and the adopting Affiliate may agree to incorporate specific provisions
         relating to the operation of the Plan that apply to the adopting
         Affiliate only and shall become, as to such adopting Affiliate and its
         employees, a part of the Plan.

         (b) The provisions of the Plan may be modified so as to increase the
         obligations of an adopting Affiliate only with the consent of such
         Affiliate, which consent shall be conclusively presumed to have been
         given by such Affiliate unless the Affiliate gives the Company written
         notice of its rejection of the amendment within 30 days after the
         adoption of the amendment.

         (c) The provisions of the Plan shall apply separately and equally to
         each adopting Affiliate and its employees in the same manner as is
         expressly provided for the Company and its employees, except that the
         power to appoint or otherwise affect the Plan Administrator and the
         power to amend or terminate the Plan shall be exercised by the Company.
         The Plan Administrator shall act as the agent for each Affiliate that
         adopts the Plan for all purposes of administration thereof.

         (d) Any adopting Affiliate may, by appropriate action of its board of
         directors or noncorporate counterpart, terminate its participation in
         the Plan. Moreover, the Plan Administrator may, in its discretion,
         terminate an Affiliate's participation in the Plan at any time.

         (e) The Plan will terminate with respect to any Affiliate that has
         adopted the Plan pursuant to this Section if the Affiliate ceases to be
         an Affiliate or revokes its adoption of the Plan by resolution of its
         board of directors or noncorporate counterpart evidenced by a written
         instrument executed by an authorized officer of the Affiliate. If the
         Plan terminates with respect to any Affiliate, the employees of that
         Affiliate will no longer be eligible to be Participants in the Plan.

7.2 SINGLE PLAN. For purposes of the Code, the Plan as adopted by the Affiliates
shall constitute a single plan rather than a separate plan of each Affiliate.

7.3 NO JOINT VENTURE IMPLIED. The document which evidences the adoption of the
Plan by an Affiliate shall become a part of the Plan. However, neither the
adoption of the Plan by an Affiliate nor any act performed by it in relation to
the Plan shall ever create a joint venture or partnership relation between it
and any other Affiliate.

                            ARTICLE 8: MISCELLANEOUS

8.1 USE OF FUNDS; NO INTEREST PAID. All funds received or held by the Company
under the Plan will be included in the general funds of the Company free of any
trust or other restriction, and may be used for any corporate purpose.
Notwithstanding any other Plan provisions to the contrary, in the event a
Participant's employment with his Employer is terminated, and if at the time of
such termination, the Participant owes money to any Employer, his Employer shall
have the right, at its discretion prior to the exercise of the Participant's
Option or the payment of the Participant's prior payroll deductions made under
the Plan, to deduct any such monies from the funds to be paid to the
Participant.

                                       9
<PAGE>

         No interest will be paid to any Participant with respect to funds held
in the Plan or funds held in the ESPP Account.

8.2 AMENDMENT TO THE PLAN. The Board or the Compensation Committee may amend the
Plan at any time and from time to time, subject to the limitation that approval
by the vote of the holders of a majority of the outstanding securities of the
Company entitled to vote shall be required to amend the Plan (i) to materially
increase the benefits accruing to Participants under the Plan, (ii) to
materially increase the number of securities which may be issued under the Plan,
or (iii) to materially modify the requirements as to eligibility for
participation in the Plan.

8.3 PLAN NOT AN EMPLOYMENT CONTRACT. The adoption and maintenance of the Plan is
not a contract between the Employers and their employees that gives any employee
the right to be retained in its employment. Likewise, it is not intended to
interfere with the rights of any Employer to terminate an Employee's employment
at any time with or without notice and with or without cause or to interfere
with an Employee's right to terminate his employment at any time.

8.4 BENEFICIARY(IES). At the time of the Participant's or former Participant's
death, (a) any cash in the Plan or (b) any cash or shares of Common Stock in the
ESPP Account shall be distributed to such Participant's or former Participant's
(a) executor or administrator or (b) his heirs at law, if there is no
administration of such Participant's or former Participant's estate. The
Participant's or former Participant's executor or administrator or heirs at law,
if there is no administration of such Participant's or former Participant's
estate, shall be such Participant's or former Participant's Beneficiaries.
Before any distribution is made, the Plan Administrator may require appropriate
written documentation of (a) the appointment of the personal representative of
the Participant's estate or (b) heirship.

8.5 SEVERABILITY. Each provision of this Agreement may be severed. If any
provision is determined to be invalid or unenforceable, that determination shall
not affect the validity or enforceability of any other provision.

8.6 BINDING EFFECT. This Agreement shall be binding upon any successor of the
Company.

8.7 LIMITATION ON LIABILITY. Under no circumstances shall the Company incur
liability for any indirect, incidental, consequential or special damages
(including lost profits) of any form incurred by any person, whether or not
foreseeable and regardless of the form of the act in which such a claim may be
brought, with respect to this Plan or the Company's role as Plan sponsor.

8.8 ARBITRATION. Any controversy arising out of or relating to the Plan,
including without limitation, any and all disputes, claims (whether in tort,
contract, statutory or otherwise) or disagreements concerning the interpretation
or application of the provisions of the Plan, Employer's employment of
Participant and the termination of that employment, shall be resolved by
arbitration in accordance with the Employee Benefit Plan Claims Arbitration
Rules of the American Arbitration Association (the "AAA") then in effect. Within
ten (10) business days of the initiation of an arbitration hereunder, the
Company and the Participant will each separately designate an arbitrator, and
within twenty (20) business days of selection, the appointed arbitrators will
appoint a neutral arbitrator from the AAA National Panel of Employee Benefit
Plan Claims Arbitrators. The arbitrators shall issue their written decision
(including a statement of finding of facts) within thirty (30) days from the
date of the close of the arbitration hearing. The decision of the arbitrators
selected hereunder will be final and binding on both parties. This arbitration
provision is expressly made pursuant to and shall be governed by the Federal
Arbitration Act, 9 U.S.C. Sections 1-16 (or replacement or successor statute).
Pursuant to Section 9 of the Federal Arbitration Act, the Company and any
Participant agrees that any judgment of the United States District Court for the
District in which the headquarters of the Company is located at the time of
initiation of an arbitration hereunder shall be entered upon the award made
pursuant to the arbitration. Nothing in this Section 8.8 shall be construed to,
in any way, limit the scope and effect of Article 6. In any arbitration
proceeding full effect shall be given to the rights, powers, and authorities of
the Plan Administrator under Article 6.

8.9 GOVERNING LAW. All provisions of the Plan shall be construed in accordance
with the laws of Texas, except to the extent preempted by federal law and except
to the extent that the conflicts of laws provisions of the State of Texas would
require the application of the relevant law of another jurisdiction, in which
event the relevant law of the State of Texas will nonetheless apply, with venue
for litigation being in Houston, Texas.
