         To be eligible for selection by the Committee to participate in the

accomplishing the purpose of the Plan.

5.       STOCK SUBJECT TO THE PLAN

         Subject to the provisions of Section 11 hereof, the maximum number and
kind of shares as to which Options or Retention Shares may at any time be
granted under the Plan are 16 million shares of Common Stock. Shares of Common
Stock subject to Options or Awards under the Plan may be either authorized but
unissued shares or shares previously issued and reacquired by the Company. Upon
the expiration, termination or cancellation (in whole or in part) of unexercised
Options, shares of Common Stock subject thereto shall again be available for
option or grant as Retention Shares under the Plan. Shares of Common Stock
covered by an Option, or portion thereof, which is surrendered upon the exercise
of a stock appreciation right, shall thereafter be unavailable for option or
grant as Retention Shares under the Plan. Upon the forfeiture (in whole or in
part) of a grant of Retention Shares, the shares of Common Stock subject to such
forfeiture shall again be available for option or grant as Retention Shares
under the Plan if no dividends have been paid on the forfeited shares, and
otherwise shall be unavailable for such an option or grant.

6.       TERMS AND CONDITIONS OF NON-QUALIFIED OPTIONS

         All non-qualified options under the Plan shall be granted subject to
the following terms and conditions:

         (a) Option Price. The option price per share with respect to each
option shall be determined by the Committee but shall not be less than 100% of
the fair market value of the Common Stock on the date the option is granted,
such fair market value to be determined in accordance with the procedures to be
established by the Committee.

         (b) Duration of Options. Options shall be exercisable at such time or
times and under such conditions as set forth in the written agreement evidencing
such option, but in no event shall any option be exercisable subsequent to the
tenth anniversary of the date on which the option is granted.



                                     - 3 -
   5

         (c) Exercise of Option. Except as provided in Section 6(h), 6(i) or
8(c), the shares of Common Stock covered by an option may not be purchased prior
to the first anniversary of the date on which the option is granted (unless the
Committee shall determine otherwise), or such longer period or periods, and
subject to such conditions, as the Committee may determine, but thereafter may
be purchased at one time or in such installments over the balance of the option
period as may be provided in the option. Any shares not purchased on the
applicable installment date may, unless the Committee shall have determined
otherwise, be purchased thereafter at any time prior to the final expiration of
the option. To the extent that the right to purchase shares has accrued
thereunder, options may be exercised from time to time by notice to the Company
stating the number of shares with respect to which the option is being
exercised.

         (d) Payment. Shares of Common Stock purchased under options shall, at
the time of purchase, be paid for in full. All, or any portion, of the option
exercise price may, at the discretion of the Committee, be paid by the surrender
to the Company, at the time of exercise, of shares of previously acquired Common
Stock owned by the Optionee, to the extent that such payment does not require
the surrender of a fractional share of such previously acquired Common Stock. In
addition, to the extent permitted by the Committee, the option exercise price
may be paid by authorizing the Company to withhold Common Stock otherwise
issuable on exercise of the option. Such shares previously acquired or shares
withheld to pay the option exercise price shall be valued at fair market value
on the date the option is exercised in accordance with the procedures to be
established by the Committee. A holder of an option shall have none of the
rights of a stockholder until the shares of Common Stock are issued to him or
her. If an amount is payable by an Optionee to the Company or a Subsidiary under
applicable withholding tax laws in connection with the exercise of non-qualified
options, the Committee may, in its discretion and subject to such rules as it
may adopt, permit the Optionee to make such payment, in whole or in part, by
electing to authorize the Company to withhold or accept shares of Common Stock
having a fair market value equal to the amount to be paid under such withholding
tax laws.

         (e) Restrictions. The Committee shall determine, with respect to each
option, the nature and extent of the restrictions, if any, to be imposed on the
shares of Common Stock which may be purchased thereunder including restrictions
on the transferability of such shares acquired through the exercise of such
option. Without limiting the generality of the foregoing, the Committee may
impose conditions restricting absolutely or conditionally the transferability of
shares acquired through the exercise of options for such periods, and subject to
such conditions, including continued employment of the Optionee by the Company
or a Subsidiary, as the Committee may determine.


                                     - 4 -
   6

         (f) Purchase for Investment. The Committee shall have the right to
require that each Optionee or other person who shall exercise an option under
the Plan represent and agree that any shares of Common Stock purchased pursuant
to such option will be purchased for investment and not with a view to the
distribution or resale thereof or that such shares will not be sold except in
accordance with such restrictions or limitations as may be set forth in the
written agreement granting such option.

         (g) Non-Transferability of Options. During an Optionee's lifetime, the
option may be exercised only by the Optionee. Options shall not be transferable,
except for exercise by the Optionee's legal representatives or heirs.

         (h) Termination of Employment. Upon the termination of an Optionee's
employment, for any reason other than death, the option shall be exercisable
only as to those shares of Common Stock which were then subject to the exercise
of such option, provided that (i) in the case of disability as described below,
any holding period required by Section 6(c) shall automatically be deemed to be
satisfied and (ii) the Committee may determine that particular limitations and
restrictions under the Plan shall not apply, and such option shall expire
according to the following schedule (unless the Committee shall provide for
shorter periods at the time the option is granted):

                  (i) Retirement. Option shall expire, unless exercised, five
         (5) years after the Optionee's retirement from the Company or any
         Subsidiary under the provisions of the Company's or a Subsidiary's
         pension plan.

                  (ii) Disability. Option shall expire, unless exercised, five
         (5) years after the date the Optionee is eligible to receive disability
         benefits under the provisions of the Company's or a Subsidiary's
         long-term disability plan.

                  (iii) Gross Misconduct. Option shall expire upon receipt by
         the Optionee of the notice of termination if he or she is terminated
         for deliberate, willful or gross misconduct as determined by the
         Company.

                  (iv) All Other Terminations. Option shall expire, unless
         exercised, three (3) months after the date of such termination;
         provided, the Committee may provide for a longer exercise period, not
         to exceed three (3) years from the date of such termination or, if
         later, three years from the date the option becomes exercisable but not
         more than five years after the date of such termination.

         (i) Death of Optionee. Upon the death of an Optionee during his or her
period of employment, the option shall be exercisable only as to those shares of
Common Stock which were subject to the exercise of such option at the time of
his or her death, provided 



                                     - 5 -
   7

that (i) any holding period required by Section 6(c) shall automatically be
deemed to be satisfied and (ii) the Committee may determine that particular
limitations and restrictions under the Plan shall not apply, and such option
shall expire, unless exercised by the Optionee's legal representatives or heirs,
five (5) years after the date of death (unless the Committee shall provide for a
shorter period at the time the option is granted).

         (j) Deferral. The Committee may permit an Optionee to elect to defer
receipt of all or part of the Common Stock issuable upon the exercise of an
option, pursuant to rules and regulations adopted by the Committee. The
Committee may permit the payment of cash in lieu of Common Stock upon payment of
the deferred amount.

In no event, however, shall any option be exercisable pursuant to Sections 6(h)
or (i) subsequent to the tenth anniversary of the date on which it is granted.

7.       TERMS AND CONDITIONS OF STOCK APPRECIATION RIGHTS

         (a) General. The Committee may also grant a stock appreciation right in
connection with a non-qualified option, either at the time of grant or by
amendment. Such stock appreciation right shall cover the same shares covered by
such option (or such lesser number of shares of Common Stock as the Committee
may determine) and shall, except for the provisions of Section 6(d) hereof, be
subject to the same terms and conditions as the related non-qualified option.

         (b) Exercise and Payment. Each stock appreciation right shall entitle
the Optionee to surrender to the Company unexercised the related option, or any
portion thereof, and to receive from the Company in exchange therefor an amount
equal to the excess of the fair market value of one share of Common Stock over
the option price per share times the number of shares covered by the option, or
portion thereof, which is surrendered. Payment shall be made in shares of Common
Stock valued at fair market value, or in cash, or partly in shares and partly in
cash, all as shall be determined by the Committee. The fair market value shall
be the value determined in accordance with procedures established by the
Committee. Stock appreciation rights may be exercised from time to time upon
actual receipt by the Company of written notice stating the number of shares of
Common Stock with respect to which the stock appreciation right is being
exercised, provided that if a stock appreciation right expires unexercised, it
shall be deemed exercised on the expiration date if any amount would be payable
with respect thereto. No fractional shares shall be issued but instead cash
shall be paid for a fraction or, if the Committee should so determine, the
number of shares shall be rounded downward to the next whole share. If an amount
is payable by an Optionee to the Company or a Subsidiary under applicable
withholding tax laws in connection with the exercise of stock appreciation
rights, the Committee may, in its discretion and subject to such rules as it 



                                     - 6 -
   8

may adopt, permit the Optionee to make such payment, in whole or in part, by
electing to authorize the Company to withhold or accept shares of Common Stock
having a fair market value equal to the amount to be paid under such withholding
tax laws.

         (c) Restrictions. The obligation of the Company to satisfy any stock
appreciation right exercised by an Optionee subject to Section 16 of the Act
shall be conditioned upon the prior receipt by the Company of an opinion of
counsel to the Company that any such satisfaction will not create an obligation
on the part of such Optionee pursuant to Section 16(b) of the Act to reimburse
the Company for any statutory profit which might be held to result from such
satisfaction.

8.       TERMS AND CONDITIONS OF INCENTIVE STOCK OPTIONS.

         (a) General. The Committee may also grant incentive stock options as
defined under section 422 of the Code. All incentive stock options issued under
the Plan shall, except for the provisions of Sections 6(h) and (i) and Section 7
hereof, be subject to the same terms and conditions as the non-qualified options
granted under the Plan. In addition, incentive stock options shall be subject to
the conditions of Sections 8(b),(c),(d) and (e).

         (b) Limitation of Exercise. The aggregate fair market value (determined
as of the date the incentive stock option is granted) of the shares of stock
with respect to which incentive stock options are exercisable for the first time
by such Optionee during any calendar year, under this Plan or any other stock
option plans adopted by the Company, its Subsidiaries or any predecessor
companies thereof, shall not exceed $100,000. If any incentive stock options
become exercisable in any year in excess of the $100,000 limitation, options
representing such excess shall become non-qualified options exercisable pursuant
to the terms of Section 6 hereof and shall not be exercisable as incentive stock
options.

         (c) Termination of Employment. Upon the termination of an Optionee's
employment, for any reason other than death, his or her incentive stock option
shall be exercisable only as to those shares of Common Stock which were then
subject to the exercise of such option provided that (i) in the case of
disability as described below, any holding period required by Section 6(c) shall
automatically be deemed to be satisfied and (ii) the Committee may determine
that particular limitations and restrictions under the Plan shall not apply, and
such option shall expire as an incentive stock option (but shall become a
non-qualified option exercisable pursuant to the terms of Section 6 hereof less
the period already elapsed under such Section), according to the following
schedule (unless the Committee shall provide for shorter periods at the time the
incentive stock option is granted):

                  (i) Retirement. An incentive stock option shall expire, unless
         exercised, three (3) months after the 



                                     - 7 -
   9

         Optionee's retirement from the Company or any Subsidiary under the 
         provisions of the Company's or a Subsidiary's pension plan.

                  (ii) Disability. In the case of an Optionee who is disabled
         within the meaning of section 22(e)(3) of the Code, an incentive stock
         option shall expire, unless exercised, one (1) year after the earlier
         of the date the Optionee terminates employment or the date the Optionee
         is eligible to receive disability benefits under the provisions of the
         Company's or a Subsidiary's long-term disability plan.

                  (iii) Gross Misconduct. An incentive stock option shall expire
         upon receipt by the Optionee of the notice of termination if he or she
         is terminated for deliberate, willful or gross misconduct as determined
         by the Company.

                  (iv) All Other Terminations. An incentive stock option shall
         expire, unless exercised, three (3) months after the date of such
         termination.

         In the case of incentive stock options granted after April 24, 1997,
the Committee may extend the period during which an incentive stock option may
be exercised as a non-qualified stock option to up to three (3) years from the
date of a termination not due to retirement, disability or gross misconduct or,
if later, three (3) years from the date the option becomes exercisable but not
more than five years after the date of such a termination.

         (d) Death of Optionee. Upon the death of an Optionee during his or her
period of employment, the incentive stock option shall be exercisable as an
incentive stock option only as to those shares of Common Stock which were
subject to the exercise of such option at the time of death, provided that (i)
any holding period required by Section 6(c) shall automatically be deemed to be
satisfied, and (ii) the Committee may determine that particular limitations and
restrictions under the Plan shall not apply, and such option shall expire,
unless exercised by the Optionee's legal representatives or heirs, five (5)
years after the date of death (unless the Committee shall provide for a shorter
period at the time the option is granted).

         (e) Leave of Absence. A leave of absence, whether or not an Approved
Leave of Absence, shall be deemed a termination of employment for purposes of
Section 8.

In no event, however, shall any incentive stock option be exercisable pursuant
to Sections 8(c) or (d) subsequent to the tenth anniversary of the date on which
it was granted.

9.       TERMS AND CONDITIONS OF AWARDS OF RETENTION STOCK



                                     - 8 -
   10

         (a) General. Retention Shares may be granted only to reward the
attainment of individual, Company or Subsidiary goals, or to attract or retain
officers or other employees of the Company or any Subsidiary, and shall be
granted subject to the attainment of performance goals unless the Committee
shall determine otherwise. With respect to each grant of Retention Shares under
the Plan, the Committee shall determine the period or periods, including any
conditions for determining such period or periods, during which the restrictions
set forth in Section 9(b) shall apply, provided that in no event, other than as
provided in Section 9(c) or in the next sentence, shall such restrictions
terminate prior to 3 years after the date of grant (the "Restriction Period"),
and may also specify any other terms or conditions to the right of the
Participant to receive such Retention Shares ("Vesting Conditions"). The
Committee may determine in its sole discretion to waive any or all of such
restrictions prior to end of the Restriction Period or the satisfaction of any
Vesting Condition. Subject to Section 9(c) and any such Vesting Condition, a
grant of Retention Shares shall be effective for the Restriction Period and may
not be revoked.

         (b) Restrictions. At the time of grant of Retention Shares to a
Participant, a certificate representing the number of shares of Common Stock
granted shall be registered in the Participant's name but shall be held by the
Company for his or her account. The Participant shall have the entire beneficial
ownership interest in, and all rights and privileges of a stockholder as to,
such Retention Shares, including the right to vote such Retention Shares and,
unless the Committee shall determine otherwise, the right to receive dividends
thereon, subject to the following: (i) subject to Section 9(c), the Participant
shall not be entitled to delivery of the stock certificate until the expiration
of the Restriction Period and the satisfaction of any Vesting Conditions; (ii)
none of the Retention Shares may be sold, transferred, assigned, pledged, or
otherwise encumbered or disposed of during the Restriction Period or prior to
the satisfaction of any Vesting Conditions; and (iii) all of the Retention
Shares shall be forfeited and all rights of the Participant to such Retention
Shares shall terminate without further obligation on the part of the Company
unless the Participant remains in the continuous employment of the Company or a
Subsidiary for the entire Restriction Period, except as provided by Sections
9(a) and 9(c), and any applicable Vesting Conditions have been satisfied. Any
shares of Common Stock or other securities or property received as a result of a
transaction listed in Section 11 shall be subject to the same restrictions as
such Retention Shares unless the Committee shall determine otherwise.

         (c)      Termination of Employment.

                  (i) Disability and Retirement. Unless the Committee shall
         determine otherwise at the time of grant of Retention Shares, if (A) a
         Participant ceases to be an employee of the Company or a Subsidiary
         prior to the end of a Restriction Period, by reason of disability under
         the provisions of the 



                                     - 9 -
   11

         Company's or a Subsidiary's long-term disability plan or retirement
         under the provisions of the Company's or a Subsidiary's pension plan
         either (i) at age 65 or (ii) prior to age 65 at the request of the
         Company or a Subsidiary, and (B) all Vesting Conditions have been
         satisfied, the Retention Shares granted to such Participant shall
         immediately vest and all restrictions applicable to such shares shall
         lapse. A certificate for such shares shall be delivered to the
         Participant in accordance with the provisions of Section 9(d).

                  (ii) Death. Unless the Committee shall determine otherwise at
         the time of grant of Retention Shares, if (A) a Participant ceases to
         be an employee of the Company or a Subsidiary prior to the end of a
         Restriction Period by reason of death, and (B) all Vesting Conditions
         have been satisfied, the Retention Shares granted to such Participant
         shall immediately vest in his or her Beneficiary, and all restrictions
         applicable to such shares shall lapse. A certificate for such shares
         shall be delivered to the Participant's Beneficiary in accordance with
         the provisions of Section 9(d).

                  (iii) All Other Terminations. If a Participant ceases to be an
         employee of the Company or a Subsidiary prior to the end of a
         Restriction Period for any reason other than death, disability or
         retirement as provided in Section 9(c)(i) and (ii), the Participant
         shall immediately forfeit all Retention Shares then subject to the
         restrictions of Section 9(b) in accordance with the provisions thereof,
         except that the Committee may, if it finds that the circumstances in
         the particular case so warrant, allow a Participant whose employment
         has so terminated to retain any or all of the Retention Shares then
         subject to the restrictions of Section 9(b) and all restrictions
         applicable to such retained shares shall lapse. A certificate for such
         retained shares shall be delivered to the Participant in accordance
         with the provisions of Section 9(d).

                  (iv) Vesting Conditions Unless the Committee shall determine
         otherwise at the time of grant of Retention Shares, if a Participant
         ceases to be an employee of the Company for any reason prior to the
         satisfaction of any Vesting Conditions, the Participant shall
         immediately forfeit all Retention Shares then subject to the
         restrictions of Section 9(b) in accordance with the provisions thereof,
         except that the Committee may, if it finds that the circumstances in
         the particular case so warrant, allow a Participant whose employment
         has so terminated to retain any or all of the Retention Shares then
         subject to the restrictions of Section 9(b) and all restrictions

         retained shares shall be delivered to the Participant in accordance

         (d) Payment of Retention Shares. At the end of the Restriction Period
and after all Vesting Conditions have been satisfied, or at such earlier time as
provided for in Section 9(c) or as the Committee, in its sole discretion, may
otherwise determine, all restrictions applicable to the Retention Shares shall
lapse, and a stock certificate for a number of shares of Common Stock equal to
the number of Retention Shares, free of all restrictions, shall be delivered to
the Participant or his or her Beneficiary, as the case may be. If an amount is
payable by a Participant to the Company or a Subsidiary under applicable
withholding tax laws in connection with the lapse of such restrictions, the
Committee, in its sole discretion, may permit the Participant to make such
payment, in whole or in part, by authorizing the Company to transfer to the
Company Retention Shares otherwise deliverable to the Participant having a fair
market value equal to the amount to be paid under such withholding tax laws.

         (e) Deferral. The Committee may permit a Participant to elect to defer
receipt of all or part of any Retention Shares that would otherwise be
delivered, pursuant to rules and regulations adopted by the Committee. The
Committee may permit the payment of cash in lieu of Common Stock upon payment of
the deferred amount.

10.      REGULATORY APPROVALS AND LISTING

         The Company shall not be required to issue to an Optionee, Participant
or a Beneficiary, as the case may be, any certificate for any shares of Common

Plan prior to (i) the obtaining of any approval from any governmental agency
which the Company, in its sole discretion, shall determine to be necessary or
advisable, (ii) the admission of such shares to listing on any stock exchange on
which the Common Stock may then be listed, and (iii) the completion of any
registration or other qualification of such shares under any state or federal
law or rulings or regulations of any governmental body which the Company, in its
sole discretion, shall determine to be necessary or advisable.

11.      ADJUSTMENT IN EVENT OF CHANGES IN CAPITALIZATION

         In the event of a recapitalization, stock split, stock dividend,
combination or exchange of shares, merger, consolidation, rights offering,
separation, spin-off, reorganization or liquidation, or any other change in the
corporate structure or shares of the Company, the Board, upon recommendation of
the Committee, may make such equitable adjustments as it may deem appropriate in
the number and kind of shares authorized by the Plan, in the option price of
outstanding Options, and in the number and kind of shares or other securities or
property subject to Options or covered by outstanding Awards.

         No Options or Retention Shares shall be granted pursuant to the Plan
after April 16, 2003, but grants of Options and Retention Shares theretofore
granted may extend beyond that date and the terms and conditions of the Plan
shall continue to apply thereto.

13.      TERMINATION OR AMENDMENT OF THE PLAN

         The Board may at any time terminate the Plan with respect to any shares
of Common Stock not at that time subject to outstanding Options or Awards, and

necessary to ensure that the Company may obtain any approval referred to in
Section 10 or to ensure that the grant of Options or Awards, the exercise of
Options or payment of Retention Shares or any other provision or the Plan
complies with Section 16(b) of the Act), provided that no change with respect to
any Options or Retention Shares theretofore granted may be made which would
impair the rights of an Optionee or Participant without the consent of such
Optionee or Participant and, further, that without the approval of stockholders,
no alteration or amendment may be made which would (i) increase the maximum
number of shares of Common Stock subject to the Plan as set forth in Section 5
(except by operation of Section 11), (ii) extend the term of the Plan or (iii)
change the class of eligible persons who may receive Options or Awards of
Retention Shares under the Plan.

14.      LEAVE OF ABSENCE

         Unless the Committee shall determine otherwise, a leave of absence
other than an Approved Leave of Absence shall be deemed a termination of
employment for purposes of the Plan. An Approved Leave of Absence shall not be
deemed a termination of employment for purposes of the Plan (except for purposes
of Section 8), but the period of such Leave of Absence shall not be counted
toward satisfaction of any Restriction Period or any holding period described in
Section 6(c).

15.      GENERAL PROVISIONS

         (a) Neither the Plan nor the grant of any Option or Award nor any
action by the Company, any Subsidiary or the Committee shall be held or
construed to confer upon any person any right to be continued in the employ of
the Company or a Subsidiary. The Company and each Subsidiary expressly reserve
the right to discharge, without liability but subject to his or her rights under
the Plan, any Optionee or Participant whenever in the sole discretion of the
Company or a Subsidiary, as the case may be, its interest may so require.

and effect of the Plan shall be determined in accordance
