                                 PACKETEER, INC.
                            1999 STOCK INCENTIVE PLAN

                AMENDED AND RESTATED EFFECTIVE AS OF MAY 23, 2001

                                   ARTICLE ONE

                               GENERAL PROVISIONS

     I.   PURPOSE OF THE PLAN

          This 1999 Stock Incentive Plan is intended to promote the interests of
Packeteer, Inc., a Delaware corporation, by providing eligible persons in the
Corporation's service with the opportunity to acquire a proprietary interest, or
otherwise increase their proprietary interest, in the Corporation as an
incentive for them to remain in such service.

          Capitalized terms shall have the meanings assigned to such terms in
the attached Appendix.

     II.  STRUCTURE OF THE PLAN

          A.   The Plan shall be divided into five separate equity programs:

               - the Discretionary Option Grant Program under which
     eligible persons may, at the discretion of the Plan Administrator, be
     granted options to purchase shares of Common Stock,

               - the Salary Investment Option Grant Program under which eligible
     employees may elect to have a portion of their base salary invested each
     year in special option grants,

               - the Stock Issuance Program under which eligible persons may, at
     the discretion of the Plan Administrator, be issued shares of Common Stock
     directly, either through the immediate purchase of such shares or as a
     bonus for services rendered the Corporation (or any Parent or Subsidiary),

               - the Automatic Option Grant Program under which eligible
     non-employee Board members shall automatically receive option grants at
     designated intervals over their period of continued Board service, and

<PAGE>

               - the Director Fee Option Grant Program under which non-employee
     Board members may elect to have all or any portion of their annual retainer
     fee otherwise payable in cash applied to a special stock option grant.

          B. The provisions of Articles One and Seven shall apply to all equity
programs under the Plan and shall govern the interests of all persons under the
Plan.

     III. ADMINISTRATION OF THE PLAN

          A. The Primary Committee shall have sole and exclusive authority to
administer the Discretionary Option Grant and Stock Issuance Programs with
respect to Section 16 Insiders. Administration of the Discretionary Option Grant
and Stock Issuance Programs with respect to all other persons eligible to
participate in those programs may, at the Board's discretion, be vested in the
Primary Committee or a Secondary Committee, or the Board may retain the power to
administer those programs with respect to all such persons. However, any
discretionary option grants or stock issuances for members of the Primary
Committee shall be made by a disinterested majority of the Board.

          B. Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and may be removed by
the Board at any time. The Board may also at any time terminate the functions of
any Secondary Committee and reassume all powers and authority previously
delegated to such committee.

          C. Each Plan Administrator shall, within the scope of its
administrative functions under the Plan, have full power and authority (subject
to the provisions of the Plan) to establish such rules and regulations as it may
deem appropriate for proper administration of the Discretionary Option Grant and
Stock Issuance Programs and to make such determinations under, and issue such
interpretations of, the provisions of those programs and any outstanding options
or stock issuances thereunder as it may deem necessary or advisable. Decisions
of the Plan Administrator within the scope of its administrative functions under
the Plan shall be final and binding on all parties who have an interest in the
Discretionary Option Grant and Stock Issuance Programs under its jurisdiction or
any option or stock issuance thereunder.

          D. The Primary Committee shall have the sole and exclusive authority
to determine which Section 16 Insiders and other highly compensated Employees
shall be eligible for participation in the Salary Investment Option Grant
Program for one or more calendar years. However, all option grants under the
Salary Investment Option Grant Program shall be made in accordance with the
express terms of that program, and the Primary Committee shall not exercise any
discretionary functions with respect to the option grants made under that
program.

          E. Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee. No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants or stock issuances under the
Plan.

                                       2.
<PAGE>

          F. Administration of the Automatic Option Grant and Director Fee
Option Grant Programs shall be self-executing in accordance with the terms of
those programs, and no Plan Administrator shall exercise any discretionary
functions with respect to any option grants or stock issuances made under those
programs.

     IV.  ELIGIBILITY

          A.   The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

                    (i) Employees,

                    (ii) non-employee members of the Board or the board of
     directors of any Parent or Subsidiary, and

                    (iii) consultants and other independent advisors who provide
     services to the Corporation (or any Parent or Subsidiary).

          B. Only Employees who are Section 16 Insiders or other highly
compensated individuals shall be eligible to participate in the Salary
Investment Option Grant Program.

          C. Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full authority to determine,
(i) with respect to the option grants under the Discretionary Option Grant
Program, which eligible persons are to receive such grants, the time or times
when those grants are to be made, the number of shares to be covered by each
such grant, the status of the granted option as either an Incentive Option or a
Non-Statutory Option, the time or times when each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding and (ii) with
respect to stock issuances under the Stock Issuance Program, which eligible
persons are to receive such issuances, the time or times when the issuances are
to be made, the number of shares to be issued to each Participant, the vesting
schedule (if any) applicable to the issued shares and the consideration for such
shares.

          D. The Plan Administrator shall have the absolute discretion either to
grant options in accordance with the Discretionary Option Grant Program or to
effect stock issuances in accordance with the Stock Issuance Program.

          E. The individuals who shall be eligible to participate in the
Automatic Option Grant Program shall be limited to (i) those individuals who
first become non-employee Board members on or after the Underwriting Date,
whether through appointment by the Board or election by the Corporation's
stockholders, and (ii) those individuals who continue to serve as non-employee
Board members at one or more Annual Stockholders Meetings held after the
Underwriting Date. A non-employee Board member who has previously been in the
employ of the Corporation (or any Parent or Subsidiary) shall NOT be eligible to
receive the initial automatic option grant under the Automatic Option Grant
Program at the time he or she first becomes a non-employee Board member, but
shall be eligible to receive one or more annual automatic option grants under
the Automatic Option Grant Program while he or she continues to serve as a
non-employee Board member.

                                       3.
<PAGE>

          F. All non-employee Board members shall be eligible to participate in
the Director Fee Option Grant Program.

     V.   STOCK SUBJECT TO THE PLAN

          A. The stock issuable under the Plan shall be shares of authorized but
unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open market. The number of shares of Common Stock reserved
for issuance over the term of the Plan shall not exceed the sum of (i) 6,659,228
shares plus (ii) the additional shares of Common Stock automatically added to
the share reserve each year pursuant to the provisions of Section V.B. of this
Article One. As of January 2, 2001, the 6,659,228-share reserve consisted of (i)
the 2,945,917 shares which remained available for issuance, as of the Plan
Effective Date, under the Predecessor Plan as last approved by the Corporation's
stockholders, including the shares subject to outstanding options under that
Predecessor Plan, (ii) an additional increase of 900,000 shares of Common Stock
approved by the Corporation's stockholders prior to the Underwriting Date, (iii)
the January 3, 2000 automatic increase of 1,340,000 shares of Common Stock plus
(iv) the January 2, 2001 automatic increase of 1,473,311 shares of Common Stock.

          B. The number of shares of Common Stock available for issuance under
the Plan shall automatically increase on the first trading day of January each
calendar year during the term of the Plan, beginning with calendar year 2000, by
an amount equal to five percent (5 %) of the total number of shares of Common
Stock outstanding on the last trading day in December of the immediately
preceding calendar year, but in no event shall any such annual increase exceed
3,000,000 shares.

          C. No one person participating in the Plan may receive options,
separately exercisable stock appreciation rights and direct stock issuances for
more than 750,000 shares of Common Stock in the aggregate per calendar year.

          D. Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plan) shall be
available for subsequent issuance under the Plan to the extent (i) those options
expire or terminate for any reason prior to exercise in full or (ii) the options
are cancelled in accordance with the cancellation-regrant provisions of Article
Two. Unvested shares issued under the Plan and subsequently cancelled or
repurchased by the Corporation at the original issue price paid per share,
pursuant to the Corporation's repurchase rights under the Plan shall be added
back to the number of shares of Common Stock reserved for issuance under the
Plan and shall accordingly be available for reissuance through one or more
subsequent option grants or direct stock issuances under the Plan. However,
should the exercise price of an option under the Plan be paid with shares of
Common Stock or should shares of Common Stock otherwise issuable under the Plan
be withheld by the Corporation in satisfaction of the withholding taxes incurred
in connection with the exercise of an option or the vesting of a stock issuance
under the Plan, then the number of shares of Common Stock available for issuance
under the Plan shall be reduced by the gross number of shares for which the
option is exercised or which vest under the stock issuance, and not by the net
number of shares of Common Stock issued to the holder of such option or stock
issuance. Shares of Common Stock underlying one or more stock appreciation
rights exercised under Section V of Article Two, Section III of Article Three,
Section II of Article Five or

                                       4.
<PAGE>

Section III of Article Six of the Plan shall NOT be available for subsequent
issuance under the Plan.

          E. If any change is made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made by the Plan Administrator to (i) the maximum number and/or class of
securities issuable under the Plan, (ii) the maximum number and/or class of
securities for which any one person may be granted stock options, separately
exercisable stock appreciation rights and direct stock issuances under the Plan
per calendar year, (iii) the number and/or class of securities for which grants
are subsequently to be made under the Automatic Option Grant Program to new and
continuing non-employee Board members, (iv) the number and/or class of
securities and the exercise price per share in effect under each outstanding
option under the Plan, (v) the number and/or class of securities and price per
share in effect under each outstanding option incorporated into this Plan from
the Predecessor Plan and (vi) the maximum number and/or class of securities by
which the share reserve is to increase automatically each calendar year pursuant
to the provisions of Section V.B. of this Article One. Such adjustments to the
outstanding options are to be effected in a manner which shall preclude the
enlargement or dilution of rights and benefits under such options. The
adjustments determined by the Plan Administrator shall be final, binding and
conclusive.

                                       5.

                                   ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM

     I.   OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
shall comply with the terms specified below. Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   EXERCISE PRICE.

               1. The exercise price per share shall be fixed by the Plan
Administrator but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the option grant date.

               2. The exercise price shall become immediately due upon exercise
of the option and shall, subject to the provisions of Section I of Article Seven
and the documents evidencing the option, be payable in one or more of the forms
specified below:

                  (i) cash or check made payable to the Corporation,

                  (ii) shares of Common Stock held for the requisite period
     necessary to avoid a charge to the Corporation's earnings for financial
     reporting purposes and valued at Fair Market Value on the Exercise Date, or

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

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B. EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable at
such time or times, during such period and for such number of shares as shall be
determined by the Plan Administrator and set forth in the documents evidencing
the option. However, no option shall have a term in excess of ten (10) years
measured from the option grant date.

                                       6.
<PAGE>

          C.   EFFECT OF TERMINATION OF SERVICE.

               1.   The following provisions shall govern the exercise of any
options held by the Optionee at the time of cessation of Service or death:

                    (i)    Any option outstanding at the time of the Optionee's
     cessation of Service for any reason shall remain exercisable for such
     period of time thereafter as shall be determined by the Plan Administrator
     and set forth in the documents evidencing the option, but no such option
     shall be exercisable after the expiration of the option term.

                    (ii) Any option held by the Optionee at the time of death
     and exercisable in whole or in part at that time may be subsequently
     exercised by the personal representative of the Optionee's estate or by the
     person or persons to whom the option is transferred pursuant to the
     Optionee's will or in accordance with the laws of descent and distribution
     or by the Optionee's designated beneficiary or beneficiaries of that
     option.

                    (iii) Should the Optionee's Service be terminated for
     Misconduct, then all outstanding options held by the Optionee shall
     terminate immediately and cease to be outstanding.

                    (iv) During the applicable post-Service exercise period,
     the option may not be exercised in the aggregate for more than the number
     of vested shares for which the option is exercisable on the date of the
     Optionee's cessation of Service. Upon the expiration of the applicable
     exercise period or (if earlier) upon the expiration of the option term, the
     option shall terminate and cease to be outstanding for any vested shares
     for which the option has not been exercised. However, the option shall,
     immediately upon the Optionee's cessation of Service, terminate and cease
     to be outstanding to the extent the option is not otherwise at that time
     exercisable for vested shares.

          2.   The Plan Administrator shall have complete discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

               (i) extend the period of time for which the option is to remain
     exercisable following the Optionee's cessation of Service from the limited
     exercise period otherwise in effect for that option to such greater period
     of time as the Plan Administrator shall deem appropriate, but in no event
     beyond the expiration of the option term, and/or

               (ii) permit the option to be exercised, during the applicable
     post-Service exercise period, not only with respect to the number of vested
     shares of Common Stock for which such option is exercisable at the time of
     the Optionee's cessation of Service but also with respect to one or more
     additional installments in which the Optionee would have vested had the
     Optionee continued in Service.

                                       7.
<PAGE>

          D. STOCKHOLDER RIGHTS. The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

          E. REPURCHASE RIGHTS. The Plan Administrator shall have the discretion
to grant options which are exercisable for unvested shares of Common Stock.
Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to repurchase, at the exercise price paid per
share, any or all of those unvested shares. The terms upon which such repurchase
right shall be exercisable (including the period and procedure for exercise and
the appropriate vesting schedule for the purchased shares) shall be established
by the Plan Administrator and set forth in the document evidencing such
repurchase right.

          F. LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of the
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or by the laws of descent
and distribution following the Optionee's death. However, a Non-Statutory Option
may, in connection with the Optionee's estate plan, be assigned in whole or in
part during the Optionee's lifetime to one or more members of the Optionee's
immediate family or to a trust established exclusively for one or more such
family members. The assigned portion may only be exercised by the person or
persons who acquire a proprietary interest in the option pursuant to the
assignment. The terms applicable to the assigned portion shall be the same as
those in effect for the option immediately prior to such assignment and shall be
set forth in such documents issued to the assignee as the Plan Administrator may
deem appropriate. Notwithstanding the foregoing, the Optionee may also designate
one or more persons as the beneficiary or beneficiaries of his or her
outstanding options under this Article Two, and those options shall, in
accordance with such designation, automatically be transferred to such
beneficiary or beneficiaries upon the Optionee's death while holding those
options. Such beneficiary or beneficiaries shall take the transferred options
subject to all the terms and conditions of the applicable agreement evidencing
each such transferred option, including (without limitation) the limited time
period during which the option may be exercised following the Optionee's death.

     II.  INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive
Options. Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Seven shall be applicable to Incentive
Options. Options which are specifically designated as Non-Statutory Options when
issued under the Plan shall not be subject to the terms of this Section II.

          A. ELIGIBILITY. Incentive Options may only be granted to Employees.

          B. DOLLAR LIMITATION. The aggregate Fair Market Value of the shares of
Common Stock (determined as of the respective date or dates of grant) for which
one or more options granted to any Employee under the Plan (or any other option
plan of the Corporation or any Parent or Subsidiary) may for the first time
become exercisable as Incentive Options during any one calendar year shall not
exceed the sum of One Hundred Thousand Dollars ($100,000).

                                       8.
<PAGE>

To the extent the Employee holds two (2) or more such options which become
exercisable for the first time in the same calendar year, the foregoing
limitation on the exercisability of such options as Incentive Options shall be
applied on the basis of the order in which such options are granted.

          C. 10% STOCKHOLDER. If any Employee to whom an Incentive Option is
granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date, and the option term shall not exceed five
(5) years measured from the option grant date.

     III. CORPORATE TRANSACTION/CHANGE IN CONTROL

          A. In the event of any Corporate Transaction, each outstanding option
shall automatically accelerate so that each such option shall, immediately prior
to the effective date of the Corporate Transaction, become fully exercisable for
the total number of shares of Common Stock at the time subject to such option
and may be exercised for any or all of those shares as fully vested shares of
Common Stock. However, an outstanding option shall NOT become exercisable on
such an accelerated basis if and to the extent: (i) such option is, in
connection with the Corporate Transaction, to be assumed by the successor
corporation (or parent thereof) or (ii) such option is to be replaced with a
cash incentive program of the successor corporation which preserves the spread
existing at the time of the Corporate Transaction on any shares for which the
option is not otherwise at that time exercisable and provides for subsequent
payout in accordance with the same exercise/vesting schedule applicable to those
option shares or (iii) the acceleration of such option is subject to other
limitations imposed by the Plan Administrator at the time of the option grant.

          B. All outstanding repurchase rights shall automatically terminate,
and the shares of Common Stock subject to those terminated rights shall
immediately vest in full, in the event of any Corporate Transaction, except to
the extent: (i) those repurchase rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.

          C. Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

          D. Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issued to the Optionee had the option been exercised immediately prior to
such Corporate Transaction. If the holders of Common Stock receive cash
consideration in connection with the Corporate Transaction, the assumed option
may be adjusted, at the option of the successor corporation, to apply to the
number of shares of its common stock with a fair market value equivalent to the
cash consideration paid per share of Common Stock in such Corporate Transaction.
Appropriate adjustments to reflect such Corporate Transaction shall also be made
to (i) the exercise price payable per share under each outstanding option,
provided the aggregate exercise price payable for such securities shall remain
the same, (ii) the maximum number and/or class of securities available for
issuance over the

                                       9.
<PAGE>

remaining term of the Plan and (iii) the maximum number and/or class of
securities for which any one person may be granted stock options, separately
exercisable stock appreciation rights and direct stock issuances under the Plan
per calendar year and (iv) the maximum number and/or class of securities by
which the share reserve is to increase automatically each calendar year.

          E. The Plan Administrator shall have the discretionary authority to
structure one or more outstanding options under the Discretionary Option Grant
Program so that those options shall, immediately prior to the effective date of
such Corporate Transaction, become fully exercisable for the total number of
shares of Common Stock at the time subject to those options and may be exercised
for any or all of those shares as fully vested shares of Common Stock, whether
or not those options are to be assumed in the Corporate Transaction. In
addition, the Plan Administrator shall have the discretionary authority to
structure one or more of the Corporation's repurchase rights under the
Discretionary Option Grant Program so that those rights shall not be assignable
in connection with such Corporate Transaction and shall accordingly terminate
upon the consummation of such Corporate Transaction, and the shares subject to
those terminated rights shall thereupon vest in full.

          F. The Plan Administrator shall have full power and authority to
structure one or more outstanding options under the Discretionary Option Grant
Program so that those options shall become fully exercisable for the total
number of shares of Common Stock at the time subject to those options in the
event the Optionee's Service is subsequently terminated by reason of an
Involuntary Termination within a designated period (not to exceed eighteen (18)
months) following the effective date of any Corporate Transaction in which those
options are assumed and do not otherwise accelerate. Any options so accelerated
shall remain exercisable for fully vested shares until the earlier of (i) the
expiration of the option term or (ii) the expiration of the one (1) year period
measured from the effective date of the Involuntary Termination. In addition,
the Plan Administrator may structure one or more of the Corporation's repurchase
rights so that those rights shall immediately terminate with respect to any
shares held by the Optionee at the time of his or her Involuntary Termination,
and the shares subject to those terminated repurchase rights shall accordingly
vest in full at that time.

          G. The Plan Administrator shall have the discretionary authority to
structure one or more outstanding options under the Discretionary Option Grant
Program so that those options shall, immediately prior to the effective date of
a Change in Control, become fully exercisable for the total number of shares of
Common Stock at the time subject to those options and may be exercised for any
or all of those shares as fully vested shares of Common Stock. In addition, the
Plan Administrator shall have the discretionary authority to structure one or
more of the Corporation's repurchase rights under the Discretionary Option Grant
Program so that those rights shall terminate automatically upon the consummation
of such Change in Control, and the shares subject to those terminated rights
shall thereupon vest in full. Alternatively, the Plan Administrator may
condition the automatic acceleration of one or more outstanding options under
the Discretionary Option Grant Program and the termination of one or more of the
Corporation's outstanding repurchase rights under such program upon the
subsequent termination of the Optionee's Service by reason of an Involuntary
Termination within a designated period (not to exceed eighteen (18) months)
following the effective date of such Change in Control. Each option so
accelerated shall remain exercisable for fully vested shares

                                      10.
<PAGE>

until the earlier of (i) the expiration of the option term or (ii) the
expiration of the one (1) year period measured from the effective date of
Optionee's cessation of Service.

          H. The portion of any Incentive Option accelerated in connection with
a Corporate Transaction or Change in Control shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
($100,000) limitation is not exceeded. To the extent such dollar limitation is
exceeded, the accelerated portion of such option shall be exercisable as a
Nonstatutory Option under the Federal tax laws.

          I. The outstanding options shall in no way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

     IV.  CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Discretionary Option
Grant Program (including outstanding options incorporated from the Predecessor
Plan) and to grant in substitution new options covering the same or different
number of shares of Common Stock but with an exercise price per share based on
the Fair Market Value per share of Common Stock on the new grant date.

     V.   STOCK APPRECIATION RIGHTS

          A. The Plan Administrator shall have full power and authority to grant
to selected Optionees tandem stock appreciation rights and/or limited stock
appreciation rights.

          B. The following terms shall govern the grant and exercise of tandem
stock appreciation rights:

                    (i) One or more Optionees may be granted the right,
     exercisable upon such terms as the Plan Administrator may establish, to
     elect between the exercise of the underlying option for shares of Common
     Stock and the surrender of that option in exchange for a distribution from
     the Corporation in an amount equal to the excess of (a) the Fair Market
     Value (on the option surrender date) of the number of shares in which the
     Optionee is at the time vested under the surrendered option (or surrendered
     portion thereof) over (b) the aggregate exercise price payable for such
     shares.

                                      11.
<PAGE>

                    (ii) No such option surrender shall be effective unless it
     is approved by the Plan Administrator, either at the time of the actual
     option surrender or at any earlier time. If the surrender is so approved,
     then the distribution to which the Optionee shall be entitled may be made
     in shares of Common Stock valued at Fair Market Value on the option
     surrender date, in cash, or partly in shares and partly in cash, as the
     Plan Administrator shall in its sole discretion deem appropriate.

                    (iii) If the surrender of an option is not approved by the
     Plan Administrator, then the Optionee shall retain whatever rights the
     Optionee had under the surrendered option (or surrendered portion thereof)
     on the option surrender date and may exercise such rights at any time prior
     to the later of (a) five (5) business days after the receipt of the
     rejection notice or (b) the last day on which the option is otherwise
     exercisable in accordance with the terms of the documents evidencing such
     option, but in no event may such rights be exercised more than ten (10)
     years after the option grant date.

          C. The following terms shall govern the grant and exercise of limited
stock appreciation rights:

                    (i) One or more Section 16 Insiders may be granted limited
     stock appreciation rights with respect to their outstanding options.

                    (ii) Upon the occurrence of a Hostile Take-Over, each
     individual holding one or more options with such a limited stock
     appreciation right shall have the unconditional right (exercisable for a
     thirty (30)-day period following such Hostile Take-Over) to surrender each
     such option to the Corporation. In return for the surrendered option, the
     Optionee shall receive a cash distribution from the Corporation in an
     amount equal to the excess of (A) the Take-Over Price of the shares of
     Common Stock at the time subject to such option (whether or not the
     Optionee is otherwise vested in those shares) over (B) the aggregate
     exercise price payable for those shares. Such cash distribution shall be
     paid within five (5) days following the option surrender date.

                    (iii) At the time such limited stock appreciation right is
     granted, the Plan Administrator shall pre-approve any subsequent exercise
     of that right in accordance with the terms of this Paragraph C.
     Accordingly, no further approval of the Plan Administrator or the Board
     shall be required at the time of the actual option surrender and cash
     distribution.

                                      12.

                                  ARTICLE THREE

                     SALARY INVESTMENT OPTION GRANT PROGRAM

     I.   OPTION GRANTS

          The Primary Committee shall have the sole and exclusive authority to
determine the calendar year or years (if any) for which the Salary Investment
Option Grant Program is to be in effect and to select the Section 16 Insiders
and other highly compensated Employees eligible to participate in the Salary
Investment Option Grant Program for such calendar year or years. Each selected
individual who elects to participate in the Salary Investment Option Grant
Program must, prior to the start of each calendar year of participation, file
with the Plan Administrator (or its designate) an irrevocable authorization
directing the Corporation to reduce his or her base salary for that calendar
year by an amount not less than Ten Thousand Dollars ($10,000.00) nor more than
Fifty Thousand Dollars ($50,000.00). Each individual who files such a timely
authorization shall automatically be granted an option under the Salary
Investment Option Grant Program on the first trading day in January of the
calendar year for which the salary reduction is to be in effect.

     II.  OPTION TERMS

          Each option shall be a Non-Statutory Option evidenced by one or more
documents in the form approved by the Plan Administrator; provided, however,
that each such document shall comply with the terms specified below.

          A.   EXERCISE PRICE.

               1. The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock
on the option grant date.

               2. The exercise price shall become immediately due upon exercise
of the option and shall be payable in one or more of the alternative forms
authorized under the Discretionary Option Grant Program. Except to the extent
the sale and remittance procedure specified thereunder is utilized, payment of
the exercise price for the purchased shares must be made on the Exercise Date.

          B.   NUMBER OF OPTION SHARES. The number of shares of Common Stock
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

               X = A / (B x 66-2/3%), where

               X is the number of option shares,

               A is the dollar amount of the reduction in the Optionee's
          base salary for the calendar year to be in effect pursuant to this
          program, and

                                      13.
<PAGE>

               B is the Fair Market Value per share of Common Stock on
          the option grant date.

          C. EXERCISE AND TERM OF OPTIONS. The option shall become exercisable
in a series of twelve (12) successive equal monthly installments upon the
Optionee's completion of each calendar month of Service in the calendar year for
which the salary reduction is in effect. Each option shall have a maximum term
of ten (10) years measured from the option grant date.

          D. EFFECT OF TERMINATION OF SERVICE. Should the Optionee cease Service
for any reason while holding one or more options under this Article Three, then
each such option shall remain exercisable, for any or all of the shares for
which the option is exercisable at the time of such cessation of Service, until
the earlier of (i) the expiration of the ten (10)-year option term or (ii) the
expiration of the three (3)-year period measured from the date of such cessation
of Service. Should the Optionee die while holding one or more options under this
Article Three, then each such option may be exercised, for any or all of the
shares for which the option is exercisable at the time of the Optionee's
cessation of Service (less any shares subsequently purchased by Optionee prior
to death), by the personal representative of the Optionee's estate or by the
person or persons to whom the option is transferred pursuant to the Optionee's
will or in accordance with the laws of descent and distribution or by the
designated beneficiary or beneficiaries of such option. Such right of exercise
shall lapse, and the option shall terminate, upon the earlier of (i) the
expiration of the ten (10)-year option term or (ii) the three (3)-year period
measured from the date of the Optionee's cessation of Service. However, the
option shall, immediately upon the Optionee's cessation of Service for any
reason, terminate and cease to remain outstanding with respect to any and all
shares of Common Stock for which the option is not otherwise at that time
exercisable.

     III. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A. In the event of any Corporate Transaction while the Optionee
remains in Service, each outstanding option held by such Optionee under this
Salary Investment Option Grant Program shall automatically accelerate so that
each such option shall, immediately prior to the effective date of the Corporate
Transaction, become fully exercisable for the total number of shares of Common
Stock at the time subject to such option and may be exercised for any or all of
those shares as fully-vested shares of Common Stock. Each such outstanding
option shall terminate immediately following the Corporate Transaction, except
to the extent assumed by the successor corporation (or parent thereof) in such
Corporate Transaction. Any option so assumed and shall remain exercisable for
the fully-vested shares until the earliest of (i) the expiration of the ten
(10)-year option term, (ii) the expiration of the three (3)-year period measured
from the date of the Optionee's cessation of Service or (iii) the surrender of
the option in connection with a Hostile Take-Over.

          B. In the event of a Change in Control while the Optionee remains in
Service, each outstanding option held by such Optionee under this Salary
Investment Option Grant Program shall automatically accelerate so that each such
option shall immediately become fully exercisable for the total number of shares
of Common Stock at the time subject to such option and may be exercised for any
or all of those shares as fully-vested shares of Common Stock.

                                      14.
<PAGE>

The option shall remain so exercisable until the earliest to occur of (i) the
expiration of the ten (10)-year option term, (ii) the expiration of the three
(3)-year period measured from the date of the Optionee's cessation of Service,
(iii) the termination of the option in connection with a Corporate Transaction
or (iv) the surrender of the option in connection with a Hostile Take-Over.

          C. Upon the occurrence of a Hostile Take-Over while the Optionee
remains in Service, the Optionee shall have a thirty (30)-day period in which to
surrender to the Corporation each outstanding option granted him or her under
the Salary Investment Option Grant Program. The Optionee shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to the surrendered option (whether or not the Optionee is otherwise at
the time vested in those shares) over (ii) the aggregate exercise price payable
for such shares. Such cash distribution shall be paid within five (5) days
following the surrender of the option to the Corporation. The Primary Committee
shall, at the time the option with such limited stock appreciation right is
granted under the Salary Investment Option Grant Program, pre-approve any
subsequent exercise of that right in accordance with the terms of this Paragraph
C. Accordingly, no further approval of the Primary Committee or the Board shall
be required at the time of the actual option surrender and cash distribution.

          D. Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction. If
the holders of Common Stock receive cash consideration in connection with the
Corporate Transaction, the assumed option may be adjusted, at the option of the
successor corporation, to apply to the number of shares of its common stock with
a fair market value equivalent to the cash consideration paid per share of
Common Stock in such Corporate Transaction. Appropriate adjustments shall also
be made to the exercise price payable per share under each outstanding option,
provided the aggregate exercise price payable for such securities shall remain
the same.

          E. The grant of options under the Salary Investment Option Grant
Program shall in no way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

     IV.  REMAINING TERMS

          The remaining terms of each option granted under the Salary Investment
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

                                      15.

                                  ARTICLE FOUR

                             STOCK ISSUANCE PROGRAM

     I.   STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below. Shares of Common Stock may also be
issued under the Stock Issuance Program pursuant to share right awards which
entitle the recipients to receive those shares upon the attainment of designated
performance goals.

          A.   PURCHASE PRICE.

               1. The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the issuance date.

               2. Subject to the provisions of Section I of Article Seven,
shares of Common Stock may be issued under the Stock Issuance Program for any of
the following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

                  (i)  cash or check made payable to the Corporation, or

                  (ii) past services rendered to the Corporation (or any
     Parent or Subsidiary).

          B.   VESTING PROVISIONS.

               1.   Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives. The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program shall be
determined by the Plan Administrator and incorporated into the Stock Issuance
Agreement. Shares of Common Stock may also be issued under the Stock Issuance
Program pursuant to share right awards which entitle the recipients to receive
those shares upon the attainment of designated performance goals.

               2.   Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or

                                      16.
<PAGE>

other change affecting the outstanding Common Stock as a class without the
Corporation's receipt of consideration shall be issued subject to (i) the same
vesting requirements applicable to the Participant's unvested shares of Common
Stock and (ii) such escrow arrangements as the Plan Administrator shall deem
appropriate.

               3. The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to the Participant under the Stock
Issuance Program, whether or not the Participant's interest in those shares is
vested. Accordingly, the Participant shall have the right to vote such shares
and to receive any regular cash dividends paid on such shares.

               4. Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares. To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to the surrendered shares.

               5. The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock which
would otherwise occur upon the cessation of the Participant's Service or the
non-attainment of the performance objectives applicable to those shares. Such
waiver shall result in the immediate vesting of the Participant's interest in
the shares of Common Stock as to which the waiver applies. Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

               6. Outstanding share right awards under the Stock Issuance
Program shall automatically terminate, and no shares of Common Stock shall
actually be issued in satisfaction of those awards, if the performance goals
established for such awards are not attained. The Plan Administrator, however,
shall have the discretionary authority to issue shares of Common Stock under one
or more outstanding share right awards as to which the designated performance
goals have not been attained.

     II.  CORPORATE TRANSACTION/CHANGE IN CONTROL

          A. All of the Corporation's outstanding repurchase rights under the
Stock Issuance Program shall terminate automatically, and all the shares of
Common Stock subject to those terminated rights shall immediately vest in full,
in the event of any Corporate Transaction, except to the extent (i) those
repurchase rights are to be assigned to the successor corporation (or parent
thereof) in connection with such Corporate Transaction or (ii) such accelerated
vesting is precluded by other limitations imposed in the Stock Issuance
Agreement.

                                      17.
<PAGE>

          B. The Plan Administrator shall have the discretionary authority to
structure one or more of the Corporation's repurchase rights under the Stock
Issuance Program so that those rights shall automatically terminate in whole or
in part, and the shares of Common Stock subject to those terminated rights shall
immediately vest, in the event the Participant's Service should subsequently
terminate by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any
Corporate Transaction in which those repurchase rights are assigned to the
successor corporation (or parent thereof).

          C. The Plan Administrator shall also have the discretionary authority
to structure one or more of the Corporation's repurchase rights under the Stock
Issuance Program so that those rights shall automatically terminate in whole or
in part, and the shares of Common Stock subject to those terminated rights shall
immediately vest, in the event the Participant's Service should subsequently
terminate by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any Change
in Control.

     III. SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

                                      18.

                                  ARTICLE FIVE

                         AUTOMATIC OPTION GRANT PROGRAM

          The provisions of the Automatic Option Grant Program have been revised
as of March 16, 2001, subject to approval by the Corporation's stockholders at
the 2001 Annual Stockholders Meeting.

     I.   OPTION TERMS

          A.   GRANT DATES. Option grants shall be made on the dates specified
below:

               1. Each individual who is first elected or appointed as a
non-employee Board member at any time on or after the 2001 Annual Stockholders
Meeting shall automatically be granted, on the date of such initial election or
appointment, a Non-Statutory Option to purchase 20,000 shares of Common Stock,
provided that individual has not previously been in the employ of the
Corporation or any Parent or Subsidiary.

               2. On the date of each Annual Stockholders Meeting, beginning
with the 2001 Annual Stockholders Meeting, each individual who is to continue to
serve as a non-employee Board member, whether or not that individual is standing
for re-election to the Board at that particular Annual Stockholders Meeting,
shall automatically be granted a Non-Statutory Option to purchase 5,000 shares
of Common Stock. There shall be no limit on the number of such annual automatic
option grants any one non-employee Board member may receive over his or her
period of Board service, and a non-employee Board member who has previously been
in the employ of the Corporation (or any Parent or Subsidiary) or who has
otherwise received one or more stock option grants from the Corporation shall be
eligible to receive one or more such annual automatic option grants over his or
her period of continued Board service.

               3. Stockholder approval of the amendment contained in this 2001
Restatement at the 2001 Annual Stockholders Meeting shall constitute
pre-approval of each option granted on or after that Annual Meeting pursuant to
the express terms of this Automatic Option Grant Program on the basis of the
amendments to this program effected by such Restatement and the subsequent
exercise of that option in accordance with its terms.

          B.   EXERCISE PRICE.

               1. The exercise price per share shall be equal to one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the option
grant date.

               2. The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

          C.   OPTION TERM.  Each option shall have a term of ten (10) years
measured from the option grant date.

                                      19.
<PAGE>

               D. EXERCISE AND VESTING OF OPTIONS. Each option shall be
immediately exercisable for any or all of the option shares. However, any shares
purchased under the option shall be subject to repurchase by the Corporation, at
the exercise price paid per share, upon the Optionee's cessation of Board
service prior to vesting in those shares. The shares subject to each initial
automatic option grant shall vest, and the Corporation's repurchase right shall
lapse, in a series of six (6) successive equal semi-annual installments upon the
Optionee's completion of each six (6)-month period of service as a Board member
over the thirty-six (36)-month period measured from the option grant date. The
shares subject to each annual automatic option grant shall be fully vested as of
the grant date.

               E. LIMITED TRANSFERABILITY OF OPTIONS. Each option under this
Article Five may, in connection with the Optionee's estate plan, be assigned in
whole or in part during the Optionee's lifetime to one or more members of the
Optionee's immediate family or to a trust established exclusively for one or
more such family members. The assigned portion may only be exercised by the
person or persons who acquire a proprietary interest in the option pursuant to
the assignment. The terms applicable to the assigned portion shall be the same
as those in effect for the option immediately prior to such assignment and shall
be set forth in such documents issued to the assignee as the Plan Administrator
may deem appropriate. The Optionee may also designate one or more persons as the
beneficiary or beneficiaries of his or her outstanding options under this
Article Five, and those options shall, in accordance with such designation,
automatically be transferred to such beneficiary or beneficiaries upon the
Optionee's death while holding those options. Such beneficiary or beneficiaries
shall take the transferred options subject to all the terms and conditions of
the applicable agreement evidencing each such transferred option, including
(without limitation) the limited time period during which the option may be
exercised following the Optionee's death.

               F. TERMINATION OF BOARD SERVICE. The following provisions shall
govern the exercise of any options held by the Optionee at the time the Optionee
ceases to serve as a Board member:

                         (i) The Optionee (or, in the event of Optionee's death,
     the personal representative of the Optionee's estate or the person or
     persons to whom the option is transferred pursuant to the Optionee's will
     or in accordance with the laws of descent and distribution or by the
     designated beneficiary or beneficiaries of such option) shall have a twelve
     (12)-month period following the date of such cessation of Board service in
     which to exercise each such option.

                         (ii) During the twelve (12)-month exercise period, the
     option may not be exercised in the aggregate for more than the number of
     vested shares of Common Stock for which the option is exercisable at the
     time of the Optionee's cessation of Board service.

                         (iii) Should the Optionee cease to serve as a Board
     member by reason of death or Permanent Disability, then all shares at the
     time subject to the option shall immediately vest so that such option may,
     during the

                                      20.
<PAGE>

     twelve (12)-month exercise period following such cessation of Board
     service, be exercised for all or any portion of those shares as
     fully-vested shares of Common Stock.

                         (iv) In no event shall the option remain exercisable
     after the expiration of the option term. Upon the expiration of the twelve
     (12)-month exercise period or (if earlier) upon the expiration of the
     option term, the option shall terminate and cease to be outstanding for any
     vested shares for which the option has not been exercised. However, the
     option shall, immediately upon the Optionee's cessation of Board service
     for any reason other than death or Permanent Disability, terminate and
     cease to be outstanding to the extent the option is not otherwise at that
     time exercisable for vested shares.

     II.  CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A. In the event of any Corporate Transaction while the Optionee
remains in Service, the shares of Common Stock at the time subject to each
outstanding option held by such Optionee under this Automatic Option Grant
Program but not otherwise vested shall automatically vest in full so that each
such option shall, immediately prior to the effective date of the Corporate
Transaction, become fully exercisable for all of the shares of Common Stock at
the time subject to such option and may be exercised for all or any portion of
those shares as fully-vested shares of Common Stock. Immediately following the
consummation of the Corporate Transaction, each automatic option grant shall
terminate and cease to be outstanding, except to the extent assumed by the
successor corporation (or parent thereof).

          B. In connection with any Change in Control while the Optionee remains
in Service, the shares of Common Stock at the time subject to each outstanding
option held by such Optionee under this Automatic Option Grant Program but not
otherwise vested shall automatically vest in full so that each such option
shall, immediately prior to the effective date of the Change in Control, become
fully exercisable for all of the shares of Common Stock at the time subject to
such option and may be exercised for all or any portion of those shares as
fully-vested shares of Common Stock. Each such option shall remain exercisable
for such fully-vested option shares until the expiration or sooner termination
of the option term or the surrender of the option in connection with a Hostile
Take-Over.

          C. All outstanding repurchase rights under this Automatic Option Grant
Program shall automatically terminate, and the shares of Common Stock subject to
those terminated rights shall immediately vest in full, in the event of any
Corporate Transaction or Change in Control.

          D. Upon the occurrence of a Hostile Take-Over while the Optionee
remains in Service, the Optionee shall have a thirty (30)-day period in which to
surrender to the Corporation each of his or her outstanding options under this
Automatic Option Grant Program. The Optionee shall in return be entitled to a
cash distribution from the Corporation in an amount equal to the excess of (i)
the Take-Over Price of the shares of Common Stock at the time subject to each
surrendered option (whether or not the Optionee is otherwise at the time vested
in those

                                      21.
<PAGE>

shares) over (ii) the aggregate exercise price payable for such shares. Such
cash distribution shall be paid within five (5) days following the surrender of
the option to the Corporation. No approval or consent of the Board or any Plan
Administrator shall be required at the time of the actual option surrender and
cash distribution.

          E. Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction. If
the holders of Common Stock receive cash consideration in connection with the
Corporate Transaction, the assumed option may be adjusted, at the option of the
successor corporation, to apply to the number of shares of its common stock with
a fair market value equivalent to the cash consideration paid per share of
Common Stock in such Corporate Transaction. Appropriate adjustments shall also
be made to the exercise price payable per share under each outstanding option,
provided the aggregate exercise price payable for such securities shall remain
the same.

          F. The grant of options under the Automatic Option Grant Program shall
in no way affect the right of the Corporation to adjust, reclassify, reorganize
or otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

     III. REMAINING TERMS

          The remaining terms of each option granted under the Automatic Option
Grant Program shall be the same as the terms in effect for option grants made
under the Discretionary Option Grant Program.

                                   ARTICLE SIX

                        DIRECTOR FEE OPTION GRANT PROGRAM

     I.   OPTION GRANTS

          The Primary Committee shall have the sole and exclusive authority to
determine the calendar year or years for which the Director Fee Option Grant
Program is to be in effect. For each such calendar year the program is in
effect, each non-employee Board member may elect to apply all or any portion of
the annual retainer fee otherwise payable in cash for his or her service on the
Board for that year to the acquisition of a special option grant under this
Director Fee Option Grant Program. Such election must be filed with the
Corporation's Chief Financial Officer prior to first day of the calendar year
for which the annual retainer fee which is the subject of that election is
otherwise payable. Each non-employee Board member who files such a timely
election shall automatically be granted an option under this Director Fee Option
Grant Program on the first trading day in January in the calendar year for which
the annual retainer fee which is the subject of that election would otherwise be
payable in cash.

     II.  OPTION TERMS

          Each option shall be a Non-Statutory Option governed by the terms and
conditions specified below.

          A. EXERCISE PRICE.

               1. The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock
on the option grant date.

               2. The exercise price shall become immediately due upon exercise
of the option and shall be payable in one or more of the alternative forms
authorized under the Discretionary Option Grant Program. Except to the extent
the sale and remittance procedure specified thereunder is utilized, payment of
the exercise price for the purchased shares must be made on the Exercise Date.

          B.   NUMBER OF OPTION SHARES. The number of shares of Common Stock
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

               X = A / (B x 66-2/3%), where

               X is the number of option shares,

               A is the portion of the annual retainer fee subject to the
          non-employee Board member's election, and

               B is the Fair Market Value per share of Common Stock on
          the option grant date.

                                      23.
<PAGE>

          C. EXERCISE AND TERM OF OPTIONS. The option shall become exercisable
in a series of twelve (12) equal monthly installments upon the Optionee's
completion of each month of Board service over the twelve (12)-month period
measured from the grant date. Each option shall have a maximum term of ten (10)
years measured from the option grant date.

          D. LIMITED TRANSFERABILITY OF OPTIONS. Each option under this Article
Six may, in connection with the Optionee's estate plan, be assigned in whole or
in part during the Optionee's lifetime to one or more members of the Optionee's
immediate family or to a trust established exclusively for one or more such
family members. The assigned portion may only be exercised by the person or
persons who acquire a proprietary interest in the option pursuant to the
assignment. The terms applicable to the assigned portion shall be the same as
those in effect for the option immediately prior to such assignment and shall be
set forth in such documents issued to the assignee as the Plan Administrator may
deem appropriate. The Optionee may also designate one or more persons as the
beneficiary or beneficiaries of his or her outstanding options under this
Article Six, and those options shall, in accordance with such designation,
automatically be transferred to such beneficiary or beneficiaries upon the
Optionee's death while holding those options. Such beneficiary or beneficiaries
shall take the transferred options subject to all the terms and conditions of
the applicable agreement evidencing each such transferred option, including
(without limitation) the limited time period during which the option may be
exercised following the Optionee's death.

          E. TERMINATION OF BOARD SERVICE. Should the Optionee cease Board
service for any reason (other than death or Permanent Disability) while holding
one or more options under this Director Fee Option Grant Program, then each such
option shall remain exercisable, for any or all of the shares for which the
option is exercisable at the time of such cessation of Board service, until the
earlier of (i) the expiration of the ten (10)-year option term or (ii) the
expiration of the three (3)-year period measured from the date of such cessation
of Board service. However, each option held by the Optionee under this Director
Fee Option Grant Program at the time of his or her cessation of Board service
shall immediately terminate and cease to remain outstanding with respect to any
and all shares of Common Stock for which the option is not otherwise at that
time exercisable.

          F. DEATH OR PERMANENT DISABILITY. Should the Optionee's service as a
Board member cease by reason of death or Permanent Disability, then each option
held by such Optionee under this Director Fee Option Grant Program shall
immediately become exercisable for all the shares of Common Stock at the time
subject to that option, and the option may be exercised for any or all of those
shares as fully-vested shares until the earlier of (i) the expiration of the ten
(10)-year option term or (ii) the expiration of the three (3)-year period
measured from the date of such cessation of Board service. Should the Optionee
die after cessation of Board service but while holding one or more options under
this Director Fee Option Grant Program, then each such option may be exercised,
for any or all of the shares for which the option is exercisable at the time of
the Optionee's cessation of Board service (less any shares subsequently
purchased by Optionee prior to death), by the personal representative of the
Optionee's estate or by the person or persons to whom the option is transferred
pursuant to the Optionee's will or in

                                      24.
<PAGE>

accordance with the laws of descent and distribution or by the designated
beneficiary or beneficiaries of such option. Such right of exercise shall lapse,
and the option shall terminate, upon the earlier of (i) the expiration of the
ten (10)-year option term or (ii) the three (3)-year period measured from the
date of the Optionee's cessation of Board service.

     III. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A. In the event of any Corporate Transaction while the Optionee
remains a Board member, each outstanding option held by such Optionee under this
Director Fee Option Grant Program shall automatically accelerate so that each
such option shall, immediately prior to the effective date of the Corporate
Transaction, become fully exercisable for the total number of shares of Common
Stock at the time subject to such option and may be exercised for any or all of
those shares as fully-vested shares of Common Stock. Each such outstanding
option shall terminate immediately following the Corporate Transaction, except
to the extent assumed by the successor corporation (or parent thereof) in such
Corporate Transaction. Any option so assumed and shall remain exercisable for
the fully-vested shares until the earliest of (i) the expiration of the ten
(10)-year option term, (ii) the expiration of the three (3)-year period measured
from the date of the Optionee's cessation of Board service or (iii) the
surrender of the option in connection with a Hostile Take-Over.

          B. In the event of a Change in Control while the Optionee remains in
Service, each outstanding option held by such Optionee under this Director Fee
Option Grant Program shall automatically accelerate so that each such option
shall immediately become fully exercisable for the total number of shares of
Common Stock at the time subject to such option and may be exercised for any or
all of those shares as fully-vested shares of Common Stock. The option shall
remain so exercisable until the earliest to occur of (i) the expiration of the
ten (10)-year option term, (ii) the expiration of the three (3)-year period
measured from the date of the Optionee's cessation of Board service, (iii) the
termination of the option in connection with a Corporate Transaction or (iv) the
surrender of the option in connection with a Hostile Take-Over.

          C. Upon the occurrence of a Hostile Take-Over while the Optionee
remains in Service, the Optionee shall have a thirty (30)-day period in which to
surrender to the Corporation each outstanding option granted him or her under
the Director Fee Option Grant Program. The Optionee shall in return be entitled
to a cash distribution from the Corporation in an amount equal to the excess of
(i) the Take-Over Price of the shares of Common Stock at the time subject to
each surrendered option (whether or not the Optionee is otherwise at the time
vested in those shares) over (ii) the aggregate exercise price payable for such
shares. Such cash distribution shall be paid within five (5) days following the
surrender of the option to the Corporation. No approval or consent of the Board
or any Plan Administrator shall be required at the time of the actual option
surrender and cash distribution.

          D. Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction. If
the holders of Common Stock receive cash consideration in

                                      25.
<PAGE>

connection with the Corporate Transaction, the assumed option may be adjusted,
at the option of the successor corporation, to apply to the number of shares of
its common stock with a fair market value equivalent to the cash consideration
paid per share of Common Stock in such Corporate Transaction. Appropriate
adjustments shall also be made to the exercise price payable per share under
each outstanding option, provided the aggregate exercise price payable for such
securities shall remain the same.

          E. The grant of options under the Director Fee Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

     IV.  REMAINING TERMS

          The remaining terms of each option granted under this Director Fee
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

                                  MISCELLANEOUS

     I.   FINANCING

          The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Discretionary Option Grant Program or the
purchase price of shares issued under the Stock Issuance Program by delivering a
full-recourse, interest bearing promissory note payable in one or more
installments. The terms of any such promissory note (including the interest rate
and the terms of repayment) shall be established by the Plan Administrator in
its sole discretion. In no event may the maximum credit available to the
Optionee or Participant exceed the sum of (i) the aggregate option exercise
price or purchase price payable for the purchased shares (less the par value of
such shares) plus (ii) any Federal, state and local income and employment tax
liability incurred by the Optionee or the Participant in connection with the
option exercise or share purchase.

     II.  TAX WITHHOLDING

          A. The Corporation's obligation to deliver shares of Common Stock upon
the exercise of options or the issuance or vesting of such shares under the Plan
shall be subject to the satisfaction of all applicable Federal, state and local
income and employment tax withholding requirements.

          B. The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan (other than the options granted or the shares issued under the Automatic
Option Grant or Director Fee Option Grant Program) with the right to use shares
of Common Stock in satisfaction of all or part of the Withholding Taxes to which
such holders may become subject in connection with the exercise of their options
or the vesting of their shares. Such right may be provided to any such holder in
either or both of the following formats:

               Stock Withholding: The election to have the Corporation withhold,
from the shares of Common Stock otherwise issuable upon the exercise of such
Non-Statutory Option or the vesting of such shares, a portion of those shares
with an aggregate Fair Market Value equal to the percentage of the Withholding
Taxes (not to exceed one hundred percent (100%)) designated by the holder.

               Stock Delivery: The election to deliver to the Corporation, at
the time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Withholding
Taxes) with an aggregate Fair Market Value equal to the percentage of the
Withholding Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

                                      27.
<PAGE>

     III. EFFECTIVE DATE AND TERM OF THE PLAN

          A. The Plan shall become effective immediately on the Plan Effective
Date. However, the Salary Investment Option Grant Program and the Director Fee
Option Grant Program shall not be implemented until such time as the Primary
Committee may deem appropriate.

          B. The Plan shall serve as the successor to the Predecessor Plan, and
no further option grants or direct stock issuances shall be made under the
Predecessor Plan after the Plan Effective Date. All options outstanding under
the Predecessor Plan on the Plan Effective Date shall be incorporated into the
Plan at that time and shall be treated as outstanding options under the Plan.
However, each outstanding option so incorporated shall continue to be governed
solely by the terms of the documents evidencing such option, and no provision of
the Plan shall be deemed to affect or otherwise modify the rights or obligations
of the holders of such incorporated options with respect to their acquisition of
shares of Common Stock.

          C. The Plan was amended and restated by the Board on March 16, 2001
(the "2001 Restatement") to (a) effect certain changes to the provisions of the
plan document in order to facilitate the administration of the Plan and (b) make
the following changes to the Automatic Option Grant Program: (i) increase the
number of shares of Common Stock for which each new non-employee Board member is
to be granted a stock option at the time of his or her initial election or
appointment to the Board from 12,000 shares to 20,000 shares, (ii) increase the
number of shares of Common Stock for which each continuing non-employee Board
member is to be granted stock options at each Annual Stockholders Meeting from
3,000 shares to 5,000 shares, beginning with the 2001 Annual Stockholders
Meeting, and (iii) eliminate, effective with the annual automatic option grants
to be made to the continuing non-employee Board members at the 2001 Annual
Stockholders Meeting, the requirement that a non-employee Board member serve in
that capacity for at least six (6) months before that individual first becomes
eligible to receive his or her first annual automatic option grant. All option
grants made prior to the 2001 Restatement shall remain outstanding in accordance
with the terms and conditions of the respective instruments evidencing those
options, and nothing in the 2001 Restatement shall be deemed to modify or in any
way affect those outstanding options.

          D. One or more provisions of the Plan, including (without limitation)
the option/vesting acceleration provisions of Article Two relating to Corporate
Transactions and Changes in Control, may, in the Plan Administrator's
discretion, be extended to one or more options incorporated from the Predecessor
Plan which do not otherwise contain such provisions.

          E. The Plan shall terminate upon the earliest to occur of (i) May 18,
2009, (ii) the date on which all shares available for issuance under the Plan
shall have been issued as fully-vested shares or (iii) the termination of all
outstanding options in connection with a Corporate Transaction. Should the Plan
terminate on May 18, 2009, then all option grants and unvested stock issuances
outstanding at that time shall continue to have force and effect in accordance
with the provisions of the documents evidencing such grants or issuances.

                                      28.
<PAGE>

     IV.  AMENDMENT OF THE PLAN

          A. The Board shall have complete and exclusive power and authority to
amend or modify the Plan in any or all respects. However, no such amendment or
modification shall adversely affect the rights and obligations with respect to
stock options or unvested stock issuances at the time outstanding under the Plan
unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws or regulations.

          B. Options to purchase shares of Common Stock may be granted under the
Discretionary Option Grant and Salary Investment Option Grant Programs and
shares of Common Stock may be issued under the Stock Issuance Program that are
in each instance in excess of the number of shares then available for issuance
under the Plan, provided any excess shares actually issued under those programs
shall be held in escrow until there is obtained stockholder approval of an
amendment sufficiently increasing the number of shares of Common Stock available
for issuance under the Plan. If such stockholder approval is not obtained within
twelve (12) months after the date the first such excess issuances are made, then
(i) any unexercised options granted on the basis of such excess shares shall
terminate and cease to be outstanding and (ii) the Corporation shall promptly
refund to the Optionees and the Participants the exercise or purchase price paid
for any excess shares issued under the Plan and held in escrow, together with
interest (at the applicable Short Term Federal Rate) for the period the shares
were held in escrow, and such shares shall thereupon be automatically cancelled
and cease to be outstanding.

     V.   USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

     VI.  REGULATORY APPROVALS

          A. The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.

          B. No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.

                                      29.

     VII. NO EMPLOYMENT/SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.
