          determined by the Committee in its sole discretion or in such other
          manner as may be specified by agreement with a Participant. In making
          such determination, the Committee may, but shall not be obligated to,

3.           Term of Plan. This Plan has been adopted by the Board and shall
     continue in effect until terminated pursuant to Section 18(a) hereof.

4.           Shares Subject to the Plan. The aggregate number of shares of
     Common Stock issuable upon the exercise of Options pursuant to this Plan
     shall be 6,066.2. The Corporation shall, during the term of this Plan,
     reserve and keep available a number of shares of Common Stock sufficient to
     satisfy the requirements of the Plan. If an Option shall expire or become
     unexercisable for any reason without having been exercised in full, then
     the shares that were subject thereto shall, unless the Plan shall have

<PAGE>

     Corporation or its Subsidiaries as shall be determined by the Committee.
     Subject to the limitations and qualifications set forth in this Plan, the
     Committee shall also determine the number of Options to be granted, the
     number of shares subject to each Option, the exercise price or prices of
     each Option, the vesting and exercise period of each Option, whether an
     Option may be exercised as to less than all of the Common Stock subject
     thereto, and such other terms and conditions of each Option, if any, as are
     consistent with the provisions of this Plan. In connection with the
     granting of Qualified Options, the aggregate Fair Market Value (determined
     at the Date of Grant of a Qualified Option) of the shares with respect to
     which Qualified Options are exercisable for the first time by a Participant
     during any calendar year (under all such plans of the Related Corporations)
     shall not exceed $100,000 or such other amount as provided in Section
     422(d) of the Code or any successor provision.

6.           Grant of Options. The Committee shall determine the number of
     shares of Common Stock to be offered from time to time pursuant to Options
     granted hereunder and shall grant Options under the Plan. The grant of
     Options shall be evidenced by Option Agreements containing such terms and
     provisions as arc approved by the Committee and executed on behalf of the
     Corporation by an appropriate officer.

7.           Time of Grant of Options. The date of grant of an Option under the
     Plan shall be the date on which the Committee awards the Option or, if the
     Committee so determines, the date specified by the Committee as the date
     the award is to be effective. Notice of the grant shall be given to each
     Participant to whom an Option is granted promptly after the date of such
     grant.

8.           Price. The Exercise Price shall be determined by the Committee at
     the Date of Grant; provided, however, that (a) the Exorcise Price for any
     Option shall not be less than 100% of the Fair Market Value of the Common
     Stock at the Date of Grant, and (b) if the Participant is a 10 Percent
     Stockholder, the Exercise Price for any Qualified Option granted to such
     Participant shall not be less than 110% of the Fair Market Value of the
     Common Stock at the Date of Grant.

9.           Vesting. Subject to Section 11 of this Plan, each Option under the
     Plan shall vest in accordance with the vesting provisions set forth in the
     applicable Option Agreement. The Committee may, but shall not be required
     to, permit acceleration of vesting upon any sale or the Corporation or
     similar transaction. The Committee may also authorize accelerated vesting
     of options based upon the occurrence of other conditions, which may be
     stated in the Option Agreement or which may be determined by the Committee
     after the date of grant of the option and implemented as to any or all
     Participants at such time. A Participant's Option Agreement may contain
     such additional provisions with respect to vesting as the Committee shall
     specify.

10.          Exercise. A Participant may pay the Exercise Price of the shares
     of Common Stock as to which an Option is being exercised by the delivery of
     cash,

                                       4

<PAGE>

     check or, with the consent of the Corporation, by the delivery of shares of
     Common Stock having a Fair Market Value on the date immediately preceding
     the exercise date equal to the Exercise Price.

     If the shares to be purchased are covered by an effective registration
statement under the Securities Act, any Option granted under the Plan may be
exercised by a broker-dealer acting on behalf of a Participant if (a) the
broker-dealer has received from the Participant or the Corporation a fully, and
duly, endorsed agreement evidencing such Option, together with instructions
signed by the Participant requesting the Corporation to deliver the shares of
Common Stock subject to such Option to the broker-dealer on behalf of the
Participant and specifying the account into which such shares shall be
deposited, (b) adequate provision has been made with respect to the payment of
any withholding taxes due upon such exercise, and (c) the broker-dealer and the
Participant have otherwise complied with Section 220.3(e)(4) of Regulation T, 12
CFR Part 220, or any successor provision.

11.          When Qualified Options May be Exercised. No Qualified Option shall
     be exercisable at any time after the expiration of ten (10) years from the
     Date of Grant; provided, however, that if the Participant with respect to a
     Qualified Option is a 10 Percent Stockholder on the Date of Grant of such
     Qualified Option, then such Option shall not be exercisable after the
     expiration of five (5) years from its Date of Grant. In addition, if a
     Participant holding a Qualified Option ceases to be an employee of the
     Corporation or any Related Corporation for any reason, such Participant's
     vested Qualified Options shall not be exercisable after (a) 30 days
     following the date such Participant ceases to be an employee of the
     Corporation or any Related Corporation, if such cessation of service is not
     due to the death or permanent and total disability (within the meaning of
     Section 22(e)(3) of the Code) of the Participant, or (b) twelve months
     following the date such Participant ceases to be an employee of the
     Corporation or any Related Corporation, if such cessation of service is due
     to the death or permanent and total disability (as defined above) of the
     Participant. Upon the death of a Participant, any vested Qualified Option
     exercisable on the date of death may be exercised by the Participant's
     estate or by a person who acquires the right to exercise such Qualified
     Option by bequest or inheritance or by reason of the death of the
     Participant, provided that such exercise occurs within both the remaining
     option term of the Qualified Option and twelve months after the date of the
     Participant's death. This Section 11 only provides the maximum exercise
     period with respect to Qualified Options; the Committee may determine that
     the exercise period for a Qualified Option shall have a shorter duration
     than as specified above.

12.          Option Financing. Upon the exercise of any Option granted under
     the Plan, the Corporation may, but is not required to. make financing
     available to the Participant for the purchase of shares of Common Stock
     pursuant to such Option on such terms as the Committee specifies.

13.          Withholding of Taxes. The Committee shall make such provisions and
     take such steps as it may deem necessary or appropriate for the withholding
     of

                                       5

<PAGE>

     any taxes that the Corporation is required by any law or regulation of any
     governmental authority to withhold in connection with any Option including,
     but not limited to, (a) withholding the issuance of all or any portion of
     the shares of Common Stock subject to such Option until the Participant
     reimburses the Corporation for the amount it is required to withhold with
     respect to such taxes, (b) canceling any portion of such issuance in an
     amount sufficient to reimburse the Corporation for the amount it is
     required to withhold or (c) taking any other action reasonably required to
     satisfy the Corporation's withholding obligation.

14.          Conditions Upon Issuance of Shares. The Corporation will not sell
     or issue any shares upon the exercise of any Option granted under the Plan
     unless the issuance and delivery of the shares complies with all provisions
     of applicable federal and state securities laws and the requirements of any
     stock exchange upon which shares of the Common Stock may then be listed.

     As a condition to the exercise of an Option, the Corporation may require
the person exercising the Option to make such representations and warranties as
may be necessary to assure the availability of an exemption from the
registration requirements of applicable federal and state securities laws.

     The Corporation will not be liable for refusing to sell or issue any shares
covered by any Option if the Corporation cannot obtain authority from the
appropriate regulatory bodies deemed by the Corporation to be necessary to
lawfully sell or issue such shares. In addition, the Corporation has no
obligation to any Participant, express or implied, to list, register or
otherwise qualify the shares of Common Stock covered by any Option.

     No Participant shall be, or shall be deemed to be, a holder of any Common
Stock subject to an Option unless and until such Participant has exercised the
Option and paid the purchase price for the subject shares of Common Stock. Each
Option under this Plan is transferable only by will or the laws of descent and
distribution and will be exercisable during the Participant's lifetime only by
the Participant.

15.          Restrictions on Shares. Shares of Common Stock issued pursuant to
     the Plan are subject to restrictions on transfer under applicable federal
     and state securities laws. The Board may impose such additional
     restrictions on the ownership and transfer of shares of Common Stock issued
     pursuant to the Plan as it deems desirable; any such restrictions shall be
     set forth in the Option Agreements entered into pursuant to this Plan.

16.          Modification or Options. At any time and from time to time, the
     Committee may execute an instrument providing for modification, extension
     or renewal of any outstanding Option, provided that no such modification,
     extension or renewal may adversely affect the rights of a Participant under
     an Option Agreement in any material respect without the consent of the
     Participant. In the event of such a modification, extension or renewal of a
     Qualified Option, the Committee may increase the exercise price of the
     Option if necessary to retain the qualified status of such Option.

                                       6

17.          Effect of Change in Stock Subject to the Plan.

     (a)        Except as may be otherwise provided in this Section 17 or in an
          Option Agreement, if the outstanding shares of Common Stock (other
          than shares held by dissenting stockholders) are changed into or
          exchanged for a different number or kind of shares of stock of the
          Corporation or of another corporation (whether by reason of merger.
          consolidation, recapitalization, reclassification, split-up,
          combination of shares or otherwise), or in the event a stock split or
          stock dividend has occurred, the Corporation or its successor shall
          substitute for each share of Common Stock then subject to Options or
          available for Options the number and kind of shares of stock or other
          property into which each outstanding share of Common Stock subject to
          Option would have been exchanged or converted pursuant to the terms of
          such transaction if, immediately prior thereto, the Participant had
          exercised his or her Option, or the number of shares of Common Stock
          as is equitably required in the event of a stock split or stock
          dividend, together with a proportionate adjustment of the Exercise
          Price under the Options, if any is appropriate in order to preserve
          the fundamental economic terms of the Option. Any such adjustment will
          not affect the vesting of Options unless otherwise expressly provided
          in this Plan or in any Option Agreement. The Board may, but is not
          required to, provide additional antidilution protection to a
          Participant under the terms of the Participant's Option Agreement.

     (b)        The existence of this Plan and any Options granted hereunder
          shall not affect in any way the right or power of the Board or the
          stockholders of the Corporation to make or authorize any adjustment,
          recapitalization, reorganization or other change in the Corporation's
          capital structure or its business, any merger or consolidation of the
          Corporation, any issue of debt or equity securities having any
          priority or preference with respect to or affecting Common Stock or
          the rights thereof, the dissolution or liquidation of the Corporation
          or any sale, lease, exchange or other disposition of all or any part
          of its assets or business or any other corporate act or proceeding.

     (c)        In the event of a Corporate Change, then no later than (i) two
          business days prior to any Corporate Change referenced in Clause (i),
          (ii) or (iii) of the definition thereof or (ii) ten business days
          after any Corporate Change referenced in Clause (iv) of the definition
          thereof, the Committee, acting in its sole discretion without the
          consent or approval of any Participant, shall act to effect one or
          more of the following alternatives with respect to outstanding
          Options, which acts may not conflict with the terms of any Option
          Agreement, may vary among individual Participants. may vary among
          Options held by individual Participants and, with respect to acts
          taken pursuant to Clause (c)(i) above, may be contingent upon
          effectuation of the Corporate Change: (A) accelerate the time at which
          Options then outstanding may be

                                       7

<PAGE>

          exercised so that such Options may be exercised in full for a limited
          period of time on or before a specified date (before or after such
          Corporate Change) fixed by the Committee, after which specified date
          all unexercised Options and all rights of Participants thereunder
          shall terminate, (B) require the mandatory surrender to the
          Corporation by selected Participants of some or all of the outstanding
          Options held by such Participants (irrespective of whether such
          Options are then exercisable under the provisions of the Plan) as of a
          date (before or after such Corporate Change) specified by the
          Committee, in which event the Committee shall thereupon cancel such
          Options and pay to each Participant an amount of cash per share equal
          to the excess, if any, of the Fair Market Value (or such other value
          as may be required or contemplated pursuant to the terms of any Option
          Agreement to be attributable to the Option in the event of the
          termination of the Participant's employment as of the date of such
          payment without "cause" or by the Participant for "good reason") of
          the shares subject to such Option over the exercise price(s) under
          such Options for such shares, (C) provide that thereafter upon any
          exercise of an Option theretofore granted the Participant shall be
          entitled to purchase under such Option, in lieu of the number of
          shares of Common Stock as to which such Option shall then be
          exercisable, the number and class of shares of stock or other
          securities or property (including, without limitation, cash) to which
          the Participant would have been entitled pursuant to the terms of the
          agreement of merger, consolidation or sale of assets or plan of
          liquidation and dissolution if, immediately prior to such merger,
          consolidation or sale of assets or any distribution in liquidation and
          dissolution of the Corporation, the Participant had been the holder of
          record of the number of shares of Common Stock then covered by such
          Option, or (D) make or grant such changes, amendments, accelerations
          or adjustments to Options and Option Agreements then outstanding as
          the Committee deems appropriate to reflect such Corporate Change
          (provided, however, that the Committee may determine in its sole
          discretion that no such changes, amendments, accelerations or
          adjustments are necessary to Options then outstanding. provided that
          no such modification, extension or renewal may adversely affect the
          rights of a Participant under an Option Agreement in any material
          respect without the consent of the Participant.).

18.       Administration.

     (a)        Options may be granted under Section 6 only by majority
          agreement of the members of the Committee. Option Agreements in the
          forms as approved by the Committee, and containing such terms and
          conditions consistent with the provisions of this Plan as have been
          determined by the Committee, may be executed on behalf of the
          Corporation by the Chairman of the Board, the President or any Vice
          President of the Corporation. The Committee has complete authority to
          construe, interpret and administer the provisions of this Plan and the

             adversely affect the rights of a Participant under any Option
             Agreement in any material respect without the consent of the

     determined to be invalid, illegal or unenforceable in whole or in part,

     obligations arising under such provision to the extent it is invalid,
     illegal or unenforceable, and such provision will be reformed to the extent
     necessary to make it legal and enforceable while preserving its intent or,

plans of the Related Corporations) shall not exceed $100,000 or such other
amount as provided in Section 422(d) of the Code or any successor provision.

containing such terms and provisions as are approved by the Committee and

         7. Time of Grant of Options. The date of grant of an Option under the
Plan shall be the date on which the Committee awards the Option or, if the
Committee so determines, the date specified by the Committee as the date the
award is to be effective. Notice of the grant shall be given to each Participant
to whom an Option is granted promptly after the date of such grant.

         8. Price. The Exercise Price shall be determined by the Committee at
the Date of Grant; provided, however, that (a) the Exercise Price for any Option
shall not be less than 100% of the Fair Market Value of the Common Stock at the
Date of Grant, and (b) if the Participant is a 10 Percent Stockholder, the
Exercise Price for any Qualified Option granted to such Participant shall not be
less than 110% of the Fair Market Value of the Common Stock at the Date of
Grant.

         9. Vesting. Subject to Section 11 of this Plan, each Option under the
Plan shall vest in accordance with the vesting provisions set forth in the
applicable Option Agreement. The Committee may, but shall not be required to,
permit acceleration of vesting upon any sale of the Corporation or similar
transaction. The Committee may also authorize accelerated vesting of options
based upon the occurrence of other conditions, which may be stated in the Option
Agreement or which may be determined by the Committee after the date of grant of
the option and implemented as to any or all Participants at such time. A
Participant's Option Agreement may contain such additional provisions with
respect to vesting as the Committee shall specify.

         10. Exercise. A Participant may pay the Exercise Price of the shares of
Common Stock as to which an Option is being exercised by the delivery of cash,
check or, with the consent of the Corporation, by the delivery of shares of
Common Stock having a Fair Market Value on the date immediately preceding the
exercise date equal to the Exercise Price.

         If the shares to be purchased are covered by an effective registration
statement under the Securities Act, any Option granted under the Plan may be
exercised by a broker-dealer acting on behalf of a Participant if (a) the
broker-dealer has received from the Participant or the Corporation a fully, and
duly. endorsed agreement evidencing such Option, together with instructions
signed by the Participant requesting the Corporation to deliver the shares of
Common Stock subject to such Option to the broker-dealer on behalf of the
Participant and specifying the account into which such shares shall be
deposited. (b) adequate provision has been made with respect to the payment of
any withholding taxes due upon such exercise, and (c) the broker-dealer and the
Participant have otherwise complied with Section 220.3(e)(4) of Regulation T, 12
CFR Part 220, or any successor provision.

         11. When Qualified Orations May be Exercised. No Qualified Option shall
be exercisable at any time after the expiration of ten (10) years from the Date
of Grant; provided, however, that if the Participant with respect to a Qualified
Option is a 10 Percent Stockholder on the Date of Grant of such Qualified
Option, then such Option shall not be exercisable after the expiration of five
(5) years from its Date of Grant. In addition, if a Participant holding a
Qualified Option ceases to be an employee of the Corporation or any Related
Corporation for any reason, such Participant's vested Qualified Options shall
not be exercisable after (a) 30 days following the date such Participant ceases
to be an employee of the Corporation or any Related

                                       4

<PAGE>

Corporation, if such cessation of service is not due to the death or permanent
and total disability (within the meaning of Section 22(e)(3) of the Code) of the
Participant, or (b) twelve months following the date such Participant ceases to
be an employee of the Corporation or any Related Corporation, if such cessation
of service is due to the death or permanent and total disability (as defined
above) of the Participant. Upon the death of a Participant, any vested Qualified
Option exercisable on the date of death may be exercised by the Participant's
estate or by a person who acquires the right to exercise such Qualified Option
by bequest or inheritance or by reason of the death of the Participant, provided
that such exercise occurs within both the remaining option term of the Qualified
Option and twelve months after the date of the Participant's death. This Section
11 only provides the maximum exercise period with respect to Qualified Options;
the Committee may determine that the exercise period for a Qualified Option
shall have a shorter duration than as specified above.

         12. Option Financing. Upon the exercise of any Option granted under the
Plan, the corporation may, but is not required to, make financing available to
the Participant for the purchase of shares of Common Stock pursuant to such
Option on such terms as the Committee specifies.

         13. Withholding of Taxes. The Committee shall make such provisions and
take such tops as it may deem necessary or appropriate for the withholding of
any taxes that the Corporation is required by any law or regulation of any
governmental authority to withhold in connection with any Option including, but
not limited to, (a) withholding the issuance of all or any portion of the shares
of Common Stock subject to such Option until the Participant reimburses the
Corporation for the amount it is required to withhold with respect to such
taxes, (b) canceling any portion of such issuance in an amount sufficient to
reimburse the Corporation for the amount it is required to withhold or (c)
taking any other action reasonably required to satisfy the Corporation's
withholding obligation.

         14. Conditions Upon Issuance of Shares. The Corporation will not sell
or issue any shares upon the exercise of any Option granted under the Plan
unless the issuance and delivery of the shares complies with all provisions of
applicable federal and state securities laws and the requirements of any stock
exchange upon which shares of the Common Stock may then be listed.

         As a condition to the exercise of an Option, the Corporation may
require the person exercising the Option to make such representations and
warranties as may be necessary to assure the availability of an exemption from
the registration requirements of applicable federal and state securities laws.

         The Corporation will not be liable for refusing to sell or issue any
shares covered by any Option if the Corporation cannot obtain authority from the
appropriate regulatory bodies deemed by the Corporation to be necessary to
lawfully sell or issue such shares. In addition, the Corporation has no
obligation to any Participant, express or implied, to list, register or
otherwise qualify the shares of Common Stock covered by any Option.

         No Participant shall be. or shall be deemed to be, a holder of any
Common Stock subject to an Option unless and until such Participant has
exercised the Option and paid the purchase price for the subject shares of
Common Stock, Each Option under this Plan is transferable only

                                       5

<PAGE>

by will or the laws of descent and distribution and will be exercisable during
the Participant's lifetime only by the Participant.

         15. Restrictions on Shares. Shares of Common Stock issued pursuant to
the Plan are subject to restrictions on transfer under applicable federal and
state securities laws. The Board may impose such additional restrictions on the
ownership and transfer of shares of Common Stock issued pursuant to the Plan as
it deems desirable; any such restrictions shall be set forth in the Option
Agreements entered into pursuant to this Plan.

         16. Modification of Options. At any time and from time to time, the
Committee may execute an instrument providing for modification, extension or
renewal of any outstanding Option, provided that no such modification, extension
or renewal may adversely affect the rights of a Participant under an Option
Agreement in any material respect without the consent of the Participant. In the
event of such a modification. extension or renewal of a Qualified Option, the
Committee may increase the exercise price of the Option if necessary to retain
the qualified status of such Option.

         17. Effect of Chance in Stock Subject to the Plan.

                  (a) Except as may be otherwise provided in this Section 17 or
         in an Option Agreement, if the outstanding shares of Common Stock
         (other than shares held by dissenting stockholders) are changed into or
         exchanged for a different number or kind of shares of stock of the
         Corporation or of another corporation (whether by reason of merger,
         consolidation, recapitalization. reclassification. split-up,
         combination of shares or otherwise), or in the event a stock split or
         stock dividend has occurred, the Corporation or its successor shall
         substitute for each share of Common Stock then subject to Options or
         available for Options the number and kind of shares of stock or other
         property into which each outstanding share of Common Stock subject to
         Option would have been exchanged or converted pursuant to the terms of
         such transaction if immediately prior thereto, the Participant had
         exercised his or her Option, or the number of shares of Common Stock as
         is equitably required in the event of a stock split or stock dividend,
         together with a proportionate adjustment of the Exercise Price under
         the Options, if any is appropriate in order to preserve the fundamental
         economic terms of the Option. Any such adjustment will not affect the
         vesting of Options unless otherwise expressly provided in this Plan or
         in any Option Agreement. The Board may, but is not required to, provide
         additional antidilution protection to a Participant under the terms of
         the Participant's Option Agreement.

                  (b) The existence of this Plan and any Options granted
         hereunder shall not affect in any way the right or power of the Board
         or the stockholders of the Corporation to make or authorize any
         adjustment, recapitalization, reorganization or other change in the
         Corporation's capital structure or its business, any merger or
         consolidation of the Corporation, any issue of debt or equity
         securities having any priority or preference with respect to or
         affecting Common Stock or the rights thereof, the dissolution or

                  (c) In the event of a Corporate Change, then no later than (i)
         two business days prior to any Corporate Change referenced in Clause
         (i), (ii) or (iii) of the definition thereof or (ii) ten business days
         after any Corporate Change referenced in Clause (iv) of the definition
         thereof, the Committee, acting in its sole discretion without the
         consent or approval of any Participant, shall act to effect one or more
         of the following alternatives with respect to outstanding Options,
         which acts may not conflict with the terms of any Option Agreement, may
         vary among individual Participants, may vary among Options held by
         individual Participants and, with respect to acts taken pursuant to
         Clause (c)(i) above, may be contingent upon effectuation of the
         Corporate Change: (A) accelerate the time at which Options then
         outstanding may be exercised so that such Options may be exercised in
         full for a limited period of time on or before a specified date (before
         or after such Corporate Change) fixed by the Committee, after which
         specified date all unexercised Options and all rights of Participants
         thereunder shall terminate, (B) require the mandatory surrender to the
         Corporation by selected Participants of some or all of the outstanding
         Options held by such Participants (irrespective of whether such Options
         are then exercisable under the provisions of the Plan) as of a date
         (before or after such Corporate Change) specified by the Committee, in
         which event the Committee shall thereupon cancel such Options and pay
         to each Participant an amount of cash per share equal to the excess. if
         any, of the Fair Market Value (or such other value as may be required
         or contemplated pursuant to the terms of any Option Agreement to be
         attributable to the Option in the event of the termination of the
         Participant's employment as of the date of such payment without "cause"
         or by the Participant for "good reason") of the shares subject to such
         Option over the exercise price(s) under such Options for such shares,
         (C) provide that thereafter upon any exercise of an Option theretofore
         granted the Participant shall be entitled to purchase under such
         Option, in lieu of the number of shares of Common Stock as to which
         such Option shall then be exercisable, the number and class of shares
         of stock or other securities or property (including, without
         limitation, cash) to which the Participant would have been entitled
         pursuant to the terms of the agreement of merger, consolidation or sale
         of assets or plan of liquidation and dissolution if, immediately prior
         to such merger, consolidation or sale of assets or any distribution in
         liquidation and dissolution of the Corporation, the Participant had
         been the holder of record of the number of shares of Common Stock then
         covered by such Option, or (D) make or grant such changes, amendments,
         accelerations or adjustments to Options and Option Agreements then
         outstanding as the Committee deems appropriate to reflect such
         Corporate Change (provided, however, that the Committee may determine
         in its sole discretion that no such changes, amendments, accelerations
         or adjustments are necessary to Options then outstanding, provided that
         no such modification, extension or renewal may adversely affect the
         rights of a Participant under an Option Agreement in any material
         respect without the consent of the Participant.).

         18. Administration.

                  (a) Options may be granted under Section 6 only by majority
         agreement of the members of the Committee. Option Agreements in the
         forms as approved by the Committee, and containing such terms and
         conditions consistent with the provisions of this Plan as have been
         determined by the Committee, may be executed on behalf of the
         Corporation by the Chairman of the Board, the President or any Vice
         President of the

                                       7

         Corporation. The Committee has complete authority to construe,
         interpret and administer the provisions of this Plan and the provisions
         of the Option Agreements executed hereunder: to prescribe, amend and
         rescind rules and regulations pertaining to this Plan: to suspend or
         discontinue this Plan; and to make all other determinations necessary
         or deemed advisable in the administration of the Plan, provided that no
         such action may adversely affect the rights of a Participant under any
         Option Agreement in any material respect without the consent of the
         Participant.. The determinations, interpretations and constructions
         made by the Committee will be final and conclusive. No member of the
         Committee will be liable for any action taken or not taken in good
         faith relating to this Plan or any award hereunder, and the members of
         the Committee are entitled to indemnification and reimbursement by the
         Corporation in respect of any claim, loss, damage or expense (including
         attorneys' fees) arising therefrom to the fullest extent permitted by
         law.

                  (b) Although the Committee may suspend or discontinue the Plan
         at any time, all Qualified Options must be granted within ten (10)
         years from the effective date of the Plan.

         19. Continued Employment Not Presumed. Nothing in this Plan or any
document describing it nor the grant of any Option gives any Participant the
right to continue in the employment of the Corporation nor affects the right of
the Corporation to terminate the employment of any such person with or without
cause.

         20. Liability of the Corporation. Neither the Corporation, its
directors, officers or employees or the Committee, nor any Subsidiary which is
in existence or hereafter comes into existence, will be liable to any
Participant or other person if it is determined for any reason by the Internal
Revenue Service or any court having jurisdiction that any Qualified Option
granted hereunder does not qualify for tax treatment as an incentive stock
option under Section 422 of the Code.

         21. Invalidity of Provisions. If any provision of this Plan is
determined to be invalid, illegal or unenforceable in whole or in part. then the
Corporation and the Participants will be relieved of all obligations arising
under such provision to the extent it is invalid, illegal or unenforceable, and
such provision will be reformed to the extent necessary to make it legal and
enforceable while preserving its intent or, if that is not possible, by
substituting therefor another provision that is legal and enforceable and
achieves the same objectives.

         22. Section Titles. All section titles and captions in this Plan are
for convenience only, shall not be deemed part of this Plan and in no way shall
define, limit, extend or describe the scope or intent of any provisions of this
Plan.

         23. GOVERNING LAW. THIS PLAN SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE SUBSTANTIVE LAWS OF THE STATE OF TEXAS AND THE UNITED
STATES, AS APPLICABLE, WITHOUT GIVING EFFECT TO ANY CONFLICT OF LAWS PROVISIONS
THAT MIGHT RESULT IN THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

                                  AMENDMENT TO

         Alon Assets, Inc., a Delaware corporation (the "Corporation"), adopts
the following amendments to the Alon Assets, Inc. 2000 Stock Option Plan (the
"Plan"), effective as of June 30, 2002, except as otherwise provided.

         1. Section 2(b) of the Plan is amended in its entirety to read as
follows:

            (b) "Common Stock" shall mean the Class B Common Stock, $.01
         par value per share of the Corporation.

         The foregoing amendment will be effective upon the filing by the
Corporation of the Certificate of Amendment to its Certificate of Incorporation
that creates the nonvoting Class B Common Stock, $.01 par value per share, of
the Corporation.

         2. The first sentence of Section 10 of the Plan ("Exercise) is amended
in its entirety to read as follows:

            A Participant may pay the Exercise Price of the shares of
            Common Stock as to which an Option is being exercised by the
            delivery of cash, check or, with the consent of the
            Corporation, by the delivery of shares of Common Stock owned
            by the Participant for at least six months and having a Fair
            Market Value on the date immediately preceding the exercise
            date equal to the Exercise Price.

         3. Section 12 of the Plan ("Option Financing") is deleted from the
Plan.

         4. Section 13 of the Plan ("Withholding of Taxes") is amended by the
addition of the following sentence:

            If the Corporation withholds shares of Common Stock to satisfy
            its withholding obligation under applicable law, such
            withholding obligation will be based upon the minimum amount
            of taxes the Corporation is required to withhold in order to
            comply with such law.

         IN WITNESS WHEREOF, the Corporation has adopted this Amendment as of
the date first written above.
