                            RUBIO'S RESTAURANTS, INC.
                            1999 STOCK INCENTIVE PLAN

                       (AS AMENDED THROUGH MARCH 6, 2003)

                                   ARTICLE ONE

                               GENERAL PROVISIONS

         I. PURPOSE OF THE PLAN

                  This 1999 Stock Incentive Plan is intended to promote the
interests of Rubio's Restaurants, 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

                           -        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.

<PAGE>

                  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, the Board acting by a disinterested majority shall have the
exclusive authority to make any discretionary option grants or stock issuances
to members of the Primary Committee.

                  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.

                  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.

                  C. 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.

                  D. 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.

                  E. 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.

                                       2.

         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 an 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 periodic option grants under the Automatic Option Grant Program while he
or she continues to serve as a non-employee Board member.

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

                                       3.

         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
initially reserved for issuance over the term of the Plan shall not exceed
2,224,608 shares. Such reserve consists of (i) the number of shares that
remained available for issuance, as of the Plan Effective Date, under the
Predecessor Plans as last approved by the Corporation's stockholders, including
the shares subject to outstanding options under that Predecessor Plans, (ii)
plus an additional increase of 500,000 shares that was approved by the
Corporation's stockholders prior to the Underwriting Date, (iii) plus an
additional increase of 266,153 shares on January 3, 2000 pursuant to the
automatic share increase provisions of Section V.B of this Article One, plus
(iv) an additional increase of 266,833 shares on January 2, 2001 pursuant to the
automatic share increase provisions of Section V.B of this Article One, plus (v)
an additional increase of 267,684 shares on January 2, 2002 pursuant to the
automatic share increase provisions of Section V.B of this Article One, plus
(vi) an additional increase of 300,000 shares that was authorized by the Board
on April 1, 2002 and approved by the Corporation's stockholders at the 2002
Annual Meeting.

                  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 three percent (3%) 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
450,000 shares.

                  C. No one person participating in the Plan may receive
options, separately exercisable stock appreciation rights and direct stock
issuances for more than 500,000 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 Plans) 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 IV of Article Two,

                                       4.
<PAGE>

Section III of Article Three, Section II of Article Five or 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 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 Plans 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.

                           1. 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.

                           2. 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.

                                       8.
<PAGE>

                  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). 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 issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments to reflect such Corporate Transaction shall also

                                       9.
<PAGE>

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 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
effect 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
effect 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

                                      10.
<PAGE>

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 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 Plans) 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.

                           (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

                                      11.
<PAGE>

         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 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 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 the Optionee's cessation of Service.

                  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.
The option shall remain so exercisable until the earliest to occur of (i) the
expiration of the ten

                                      14.
<PAGE>

(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, 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.
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.

                             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 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

                                      16.
<PAGE>

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.

                  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

                                      17.
<PAGE>

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.

individual has served as a non-employee Board member for at least six (6)
months. There shall be no limit on the number of such 5,000 share option grants
any one Eligible Director may receive over his or her period of Board service,
and non-employee Board members who have previously been in the employ of the
Corporation (or any Parent or Subsidiary) or who have otherwise received one or
more stock option grants from the Corporation prior to the Underwriting Date
shall be eligible to receive such annual option grants over their period of
continued Board service.

                  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.

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 Three, 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 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
the designated beneficiary or beneficiaries of such option) shall have a twelve
(12)-month period following the date the Optionee ceases to serve as a Board
member in which to exercise each option the Optionee holds at the time of such
cessation of Board service. In no event shall the option remain exercisable
after the expiration of the option term.

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

                  A. Immediately following the consummation of any 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. Upon the occurrence of a Hostile Take-Over, the Optionee
shall have a thirty (30)-day period in which to surrender to the Corporation
each of his or her outstanding automatic option grants. 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 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. Stockholder
approval of the Plan shall constitute pre-approval of the grant of each such
limited cash-out right and the subsequent exercise of that right in accordance
with the terms of this Paragraph D. Accordingly, 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.

                  C. 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.
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.

<PAGE>

                  D. 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.

                        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 (notwithstanding the foregoing, the Board may permit certain
elections to be made at any time prior to the date the fee would otherwise be
paid). 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 (notwithstanding the foregoing, if the Board permits deferrals to be made
at any time prior to the date the fees would otherwise be paid, in those
instances, the date of the grant pursuant to this section shall be the date
following such election to defer).

         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,

                                      22.
<PAGE>

                           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.

                  C. EXERCISE AND TERM OF OPTIONS. The option shall become
exercisable on the earliest of death, Permanent Disability, termination of Board
services for any reason other than voluntary resignation prior to the expiration
of the director's term on the Board or three months from the date of grant. 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 grant 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 Three, 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.

                                      23.
<PAGE>

                  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
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 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 the Optionee's cessation of Board
service.

                  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, 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. Stockholder approval of the Plan shall constitute
pre-approval of the grant of each such limited cash-out right and the subsequent
exercise of that right in accordance with the terms of this Paragraph C.
Accordingly, no approval or consent of

                                      24.
<PAGE>

the Board or any Plan Administrator shall be required at the time of the actual
option surrender and cash distribution.

                  D. 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 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.

                                      26.
<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. Options may be granted under the
Discretionary Option Grant at any time on or after the Plan Effective Date.
However, no options granted under the Plan may be exercised, and no shares shall
be issued under the Plan, until the Plan is approved by the Corporation's
stockholders. If such stockholder approval is not obtained within twelve (12)
months after the Plan Effective Date, then all options previously granted under
this Plan shall terminate and cease to be outstanding, and no further options
shall be granted and no shares shall be issued under the Plan.

                  B. The Plan shall serve as the successor to the Predecessor
Plans, and no further option grants or direct stock issuances shall be made
under the Predecessor Plans after the Plan Effective Date. All options
outstanding under the Predecessor Plans 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. 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 Plans which do not otherwise contain such provisions.

                  D. The Plan shall terminate upon the earliest to occur of (i)
March 17, 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 March 17, 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.

         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

                                      27.
<PAGE>

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.

                  C. Effective as of April 1, 2002, the Board amended the Plan
to increase the maximum number of shares of Common Stock authorized for issuance
over the term of the Plan from 1,924,608 shares to 2,224,608 shares. This
amendment was approved by the stockholders at the 2002 Annual Meeting.

         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.

         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.
