               2.1  Shares Subject to Plan.

               Common Stock, subject to Section 8.3 of the Plan.  The aggregate

               Stock issuable upon exercise of such Options may be either
               previously authorized but unissued shares or treasury shares.



                      (b)  The maximum number of shares of Common Stock which
               may be subject to Options granted under the Plan to any
               individual in any calendar year shall not exceed the Option
               Limit. To the extent required by Section 162(m) of the Code,
               shares subject to Options which are canceled continue to be
               counted against the Option Limit.

without having been fully exercised, or is exercised in whole or in part for
cash as permitted by the Plan, the number of shares of Common Stock subject to

expiration or cancellation may again be optioned, granted or awarded hereunder,
subject to the limitations of Section 2.1.  Furthermore, any shares subject to
Options which are adjusted pursuant to Section 8.3 and become exercisable with
respect to shares of stock of another corporation shall be considered cancelled
and may again be optioned, granted or awarded hereunder, subject to the
limitations of Section 2.1.  Notwithstanding the provisions of this Section
2.2, no shares of Common Stock may again be optioned, granted or awarded
hereunder if such action would cause an Incentive Stock Option to fail to
qualify as an "incentive stock option" under Section 422 of the Code.



                                     ARTICLE III.

                      (b)  Notwithstanding anything in the Plan to the

               162(m) Employee, the restrictions to which lapse upon the

               of the Performance Criteria, that vests or becomes exercisable
               or payable upon the attainment of performance goals which are
               related to one or more of the Performance Criteria.

                      (c)  To the extent necessary to comply with the
               performance-based compensation requirements of Section 162(m)(4)

               Employee, the Committee shall have the right to reduce (but not
               to increase) the amount payable at a given level of performance
               to take into account additional factors that the Committee may
               deem relevant to the assessment of individual or corporate
               performance for the fiscal year or other designated fiscal
               period or period of service.



                      (d)  Furthermore, notwithstanding any other provision of
               the Plan, any Option which is granted to a Section 162(m)
               Employee and is intended to qualify as performance-based
               compensation as described in Section 162(m)(4)(C) of the Code
               shall be subject to any additional limitations set forth in
               Section 162(m) of the Code (including any amendment to Section
               162(m) of the Code) or any regulations or rulings issued
               thereunder that are requirements for qualification as
               performance-based compensation as described in Section 162(m)(4)
               (C) of the Code, and the Plan and such Options shall be deemed
               amended to the extent necessary to conform to such requirements.


               3.3  Limitations Applicable to Section 16 Persons.

granted to any individual who is then subject to Section 16 of the Exchange
Act, shall be subject to any additional limitations set forth in any applicable
exemptive rule under Section 16 of the Exchange Act (including any amendment to

Options granted hereunder shall be deemed amended to the extent necessary to

               3.4  At-Will Employment. Nothing in the Plan or in any Option
Agreement hereunder shall confer upon any Holder any right to continue in the
employ of the Company or any Subsidiary or shall interfere with or restrict in
any way the rights of the Company and any Subsidiary, which are hereby
expressly reserved, to discharge any Holder at any time for any reason
whatsoever, with or without cause, except to the extent expressly provided

                      Code.

               4.5  Options in Lieu of Cash Compensation. Options may be
granted under the Plan to Employees in lieu of cash bonuses which would
otherwise be payable to such Employees pursuant to such policies which may be
adopted by the Administrator from time to time.

                                      ARTICLE V.
                                   TERMS OF OPTIONS



               5.1  Option Price. The price per share of the shares of Common
Stock subject to each Option granted to Employees shall be set by the Committee
at the time the Option is granted; provided, however, that such price shall be
no less than 100% of the Fair Market Value of a share of Common Stock on the
date the Option is granted, and in the case of Incentive Stock Options granted
to an individual then owning (within the meaning of Section 424(d) of the Code)
more than 10% of the total combined voting power of all classes of stock of the
Company or any Subsidiary or parent corporation thereof (within the meaning of
Section 422 of the Code), such price shall not be less than 110% of the Fair
Market Value of a share of Common Stock on the date the Option is granted.



               5.2  Option Term. The term of an Option granted to an Employee
shall be set by the Committee in its absolute discretion; provided, however,
that the term shall not be more than ten (10) years from the date the Option
is granted; and, provided, further, that, in the case of Incentive Stock
Options, the term shall not be more than five (5) years from the date the
Incentive Stock Option is granted if the Incentive Stock Option is granted
to an individual then owning (within the meaning of Section 424(d) of the Code)
more than 10% of the total combined voting power of all classes of stock of
the Company or any Subsidiary or parent corporation thereof (within the meaning
of Section 422 of the Code).  Except as limited by requirements of Section 422
of the Code and regulations and rulings thereunder applicable to Incentive
Stock Options, the Committee may extend the term of any outstanding Option in
connection with any Termination of Employment of the Holder by up to four (4)
years, or amend any other term or condition of such Option relating to such a
termination.


               5.3  Option Vesting

                      (a)  The period during which the right to exercise, in
               whole or in part, an Option granted to an Employee vests in the
               Holder shall be set by the Committee and the Committee may
               determine that an Option may not be exercised in whole or in
               part for a specified period after it is granted.  At any time
               after grant of an Option, the Committee may, in its absolute
               discretion and subject to whatever terms and conditions it
               selects, accelerate the period during which an Option granted
               to an Employee vests and becomes exercisable.

                      (b)  No portion of an Option granted to an Employee which
               is unexercisable at Termination of Employment shall thereafter
               become exercisable, except as may be otherwise provided by the

                                       8


<page>

               Committee either in the Option Agreement or by action of the
               Committee following the grant of the Option.

                      (c)  To the extent that the aggregate Fair Market Value
               of stock with respect to which "incentive stock options" (within
               the meaning of Section 422 of the Code, but without regard to
               Section 422(d) of the Code) are exercisable for the first time
               by a Holder during any calendar year (under the Plan and all
               other incentive stock option plans of the Company and any parent
               or subsidiary corporation (within the meaning of Section 422 of
               the Code) of the Company), exceeds $100,000, such Options or
               other options shall be treated as non-qualified stock options to
               the extent required by Section 422 of the Code.  The rule set
               forth in the preceding sentence shall be applied by taking
               Options or other options into account in the order in which they
               were granted.  For purposes of this Section 5.3(c), the Fair
               Market Value of stock shall be determined as of the time the
               Option or other options with respect to such stock is granted.


               5.4  Substitute Options. Notwithstanding the foregoing
provisions of this Article V to the contrary, in the case of an Option that is
a Substitute Option, the price per share of the shares subject to such Option
may be less than the Fair Market Value per share on the date of grant,
provided, that the excess of:

                      (a)  the aggregate Fair Market Value (as of the date such
               Substitute Option is granted) of the shares subject to the
               Substitute Option; over

                      (b)  the aggregate exercise price thereof; does not
               exceed the excess of;

                      (c)  the aggregate fair market value (as of the time
               immediately preceding the transaction giving rise to the
               Substitute Option, such fair market value to be determined
               by the Administrator) of the shares of the predecessor entity
               that were subject to the grant assumed or substituted for by
               the Company; over

                      (d)  the aggregate exercise price of such shares.


             5.5  Restrictions on Common Stock. The Administrator may, in
its sole discretion, provide under the terms of an Option that shares of
Common Stock purchased upon exercise of such Option shall be subject to
repurchase from the Holder by the Company, or shall be subject to such
restrictions as the Administrator shall provide, which restrictions may
include, without limitation, restrictions concerning voting rights and
transferability and restrictions based on duration of employment with the
Company and the Subsidiaries, Company performance and individual performance;
provided, however, that, by action taken after the Common Stock is purchased
upon exercise of the Option, the Administrator may, on such terms and
conditions as it may determine to be appropriate, terminate the Company's
repurchase right or remove any or all of the restrictions imposed by the terms
of the Option Agreement. The Company's right to repurchase the Common Stock
from the Holder then subject to the right shall provide that immediately upon
a Termination of Employment and for such period as the Administrator shall

                                       9

<page>

determine, the Company shall have the right to purchase the Common Stock at
a price per share equal to the price paid by the Holder for such Common Stock,
or such other price as is determined by the Administrator; provided, however,
that, in the event of a Change in Control, such right of repurchase shall
terminate immediately prior to the effective date of such Change in Control.
Shares of Common Stock purchased upon the exercise of an Option may not be
sold, transferred or encumbered until any repurchase right and any and all
restrictions are terminated or expire.  The Secretary of the Company or such
other escrow holder as the Administrator may appoint shall retain physical
custody of each certificate representing such shares of Common Stock until
the repurchase right and any and all of the restrictions imposed under the
Option Agreement with respect to the shares evidenced by such certificate
terminate, expire or shall have been removed.  In order to enforce the
restrictions imposed upon shares of Common Stock hereunder, the Administrator
shall cause a legend or legends to be placed on certificates representing all
shares of Common Stock that are still subject to any repurchase right or
restrictions under Option Agreements, which legend or legends shall make
appropriate reference to the conditions imposed thereby.  If a Holder makes an
election under Section 83(b) of the Code, or any successor section thereto, to
be taxed with respect to the Common Stock as of the date of transfer of the
Common Stock rather than as of the date or dates upon which the Holder would
otherwise be taxable under Section 83(a) of the Code, the Holder shall deliver
a copy of such election to the Company immediately after filing such election
with the Internal Revenue Service.

                                     ARTICLE VI.

                                 EXERCISE OF OPTIONS


               6.1  Partial Exercise. An exercisable Option may be exercised in
whole or in part. However, an Option shall not be exercisable with respect to
fractional shares and the Administrator may require that, by the terms of the
Option, a partial exercise be with respect to a minimum number of shares.

               6.2  Manner of Exercise. All or a portion of an exercisable
Option shall be deemed exercised upon delivery of all of the following to the
Secretary of the Company or his office:

                      (a) A written notice complying with the applicable rules
               established by the Administrator stating that the Option, or a
               portion thereof, is exercised. The notice shall be signed by the
               Holder or other person then entitled to exercise the Option or
               such portion of the Option;


                      (b) Such representations and documents as the
               Administrator, in its absolute discretion, deems necessary or
               advisable to effect compliance with all applicable provisions of
               the Securities Act and any other federal or state securities
               laws or regulations.  The Administrator may, in its absolute
               discretion, also take whatever additional actions it deems
               appropriate to effect such compliance including, without
               limitation, placing legends on share certificates and issuing
               stop-transfer notices to agents and registrars;

                                       10

<page>

                    (c) In the event that the Option shall be exercised
               pursuant to Section 8.1 by any person or persons other than the
               Holder, appropriate proof of the right of such person or persons
               to exercise the Option; and


                    (d) Full cash payment (or cash equivalent) to the Secretary
               of the Company for the shares with respect to which the Option,
               or portion thereof, is exercised.



               6.3  Conditions to Issuance of Stock Certificates.The Company
shall not be required to issue or deliver any certificate or certificates for
shares of stock purchased upon the exercise of any Option or portion thereof
prior to fulfillment of all of the following conditions:


                      (a)  The admission of such shares to listing on all stock
               exchanges on which such class of stock is then listed;

                      (b)  The completion of any registration or other
               qualification of such shares under any state or federal law, or
               under the rulings or regulations of the Securities and Exchange
               Commission or any other governmental regulatory body which the
               Administrator shall, in its absolute discretion, deem necessary
               or advisable;

                      (c)  The obtaining of any approval or other clearance
               from any state or federal governmental agency which the
               Administrator shall, in its absolute discretion, determine to be
               necessary or advisable;

                      (d)  The lapse of such reasonable period of time
               following the exercise of the Option as the Administrator may
               establish from time to time for reasons of administrative
               convenience; and

                      (e)  The receipt by the Company of full payment for such
               shares, including payment of any applicable withholding tax.


               6.4  Rights as Stockholders. Holders shall not be, nor have any
of the rights or privileges of, stockholders of the Company in respect of any
shares purchasable upon the exercise of any part of an Option unless and until
certificates representing such shares have been issued by the Company to such
Holders.


               6.5  Ownership and Transfer Restrictions. The Administrator, in
its absolute discretion, may impose such restrictions on the ownership and
transferability of the shares purchasable upon the exercise of an Option as it
deems appropriate.  Any such restriction shall be set forth in the respective
Option Agreement and may be referred to on the certificates evidencing such
shares.  The Holder shall give the Company prompt notice of any disposition of
shares of Common Stock acquired by exercise of an Incentive Stock Option within
(a) two years from the date of granting (including the date the Option is
modified, extended or renewed for purposes of Section 424(h) of the Code) such
Option to such Holder or (b) one year after the transfer of such shares to such
Holder.

               6.6  Additional Limitations on Exercise of Options. Holders may
be required to comply with any timing or other restrictions with respect to
the settlement or exercise of an Option, including a window-period limitation,
as may be imposed in the discretion of the Administrator.

functions.


               7.2  Duties and Powers of Committee. It shall be the duty of

with its provisions. The Committee shall have the power to interpret the Plan
and the Option Agreements, and to adopt such rules for the administration,
interpretation, and application of the Plan as are consistent therewith, to
interpret, amend or revoke any such rules and to amend any Option Agreement
provided that the rights or obligations of the Holder of the Option that is
the subject of any such Option Agreement are not affected adversely.  Any such
interpretations and rules with respect to Incentive Stock Options shall be
consistent with the provisions of Section 422 of the Code.  In its absolute
discretion, the Board may at any time and from time to time assume any and all
rights and duties of the Committee under the Plan, except with respect to
matters which under Rule 16b-3 or Section 162(m) of the Code, or any

                               MISCELLANEOUS PROVISIONS



               8.1  Not Transferable. No Option under the Plan may be sold,
pledged, assigned or transferred in any manner other than by will or the laws
of descent and distribution or, subject to the consent of the Administrator,
pursuant to a DRO, unless and until such Option has been exercised, or the
shares underlying such Option have been issued, and all restrictions
applicable to such shares have lapsed.  No Option or interest or right therein
shall be liable for the debts, contracts or engagements of the Holder or his
successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect, except to the extent that such disposition
is permitted by the preceding sentence.


               During the lifetime of the Holder, only he may exercise an
Option (or any portion thereof) granted to him under the Plan, unless it has
been disposed of with the consent of the Administrator pursuant to a DRO.
After the death of the Holder, any exercisable portion of an Option may, prior
to the time when such portion becomes unexercisable under the Plan or the
applicable Option Agreement, be exercised by his personal representative or by
any person empowered to do so under the deceased Holder's will or under the
then applicable laws of descent and distribution.


               Notwithstanding the foregoing provisions of this Section 8.1,
the Administrator, in its sole discretion, may determine to grant a
Non-Qualified Stock Option which, by its terms as set forth in the applicable
Option Agreement, may be transferred by the Holder, in writing and with prior
written notice to the Administrator, to any one or more Permitted Transferees
(as defined below), subject to the following terms and conditions: (a) a
Non-Qualified Stock Option transferred to a Permitted Transferee shall not be
assignable or transferable by the Permitted Transferee other than by will or
the laws of descent and distribution; (b) any Non-Qualified Stock Option which
is transferred to a Permitted Transferee shall continue to be subject to all
the terms and conditions of the Non-Qualified Stock Option as applicable to
the original Holder (other than the ability to further transfer the
Non-Qualified Stock Option); and (c) the Holder and the Permitted Transferee
shall execute any and all documents requested by the Administrator, including,
without limitation, documents to:  (i) confirm the status of the transferee as
a Permitted Transferee, (ii) satisfy any requirements for an exemption for the
transfer under applicable federal and state securities laws and (iii) evidence
the  transfer.  For purposes of this Section, "Permitted Transferee" shall
mean, with respect to a Holder, any child, stepchild, grandchild, parent,
stepparent, grandparent, spouse, former  spouse, sibling, niece, nephew,
mother-in-law, father-in-law, daughter-in-law, brother-in-law, or
sister-in-law, including adoptive relationships, any person sharing the
Holder's household (other than a tenant or employee), a trust in which these
persons (or the Holder) control the management of assets, and any other
entity in which these persons (or the Holder) owns more than fifty percent
(50%) of the voting interests, or any other transferee specifically approved
by the Administrator after taking into account any state or federal tax or
securities laws applicable to transferable Non-Qualified Stock Options.

                      (a)  Except as otherwise provided in this Section 8.2,
               the Plan may be wholly or partially amended or otherwise
               modified, suspended or terminated at any time or from time to
               time by the Board.  However, without approval of the Company's
               stockholders given within twelve months before or after the
               action by the Board, no action of the Board may, except as
               provided in Section 8.3, increase the limits imposed in Section
               2.1 on the maximum number of shares which may be issued under
               the Plan.



                       (b)  No amendment, suspension or termination of the Plan
               shall, without the consent of the Holder alter or impair any
               rights or obligations under any Option theretofore granted,
               unless the Option itself otherwise expressly so provides.



                      (c)  No Options may be granted during any period of
               suspension or after termination of the Plan, and in no event may
               any Option be granted under the Plan after the first to occur of
               the following events:

                          (i)  The expiration of ten years from the date the
                      Plan is adopted by the Board; or

                          (ii) The expiration of ten years from the date the
                      Plan is approved by the Company's stockholders under
                      Section 8.5.


               8.3  Changes in Common Stock or Assets of the Company,
          Acquisition or Liquidation of the Company and Other Corporate Events.


                      (a)  Subject to Section 8.3(d), in the event that the
               Administrator determines that any dividend or other distribution
               (whether in the form of cash, Common Stock, other securities, or
               other property), recapitalization, reclassification, stock
               split, reverse stock split, reorganization, merger,
               consolidation, split-up, spin-off, combination, repurchase,
               liquidation, dissolution, or sale, transfer, exchange or other
               disposition of all or substantially all of the assets of the
               Company, or exchange of Common Stock or other securities of the
               Company, issuance of warrants or other rights to purchase Common
               Stock or other securities of the Company, or other similar
               corporate transaction or event, in the Administrator's sole
               discretion, affects the Common Stock such that an adjustment is
               determined by the Administrator to be appropriate in order to
               prevent dilution or enlargement of the benefits or potential
               benefits intended to be made available under the Plan or with
               respect to an Option, then the Administrator shall, in such
               manner as it may deem equitable, adjust any or all of:


                           (i)the number and kind of shares of Common Stock
                      (or other securities or property) with respect to which
                      Options may be granted (including, but not limited to,
                      adjustments of the limitations in Section 2.1 on the
                      maximum number and kind of shares which may be issued
                      and adjustments of the Option Limit);

                           (ii)the number and kind of shares of Common Stock

                      Options; and

                           (iii)the grant or the exercise price with respect
                      to any Option.


                      (b)  Subject to Section 8.3(d), in the event of any
               transaction or event described in Section 8.3(a) or any unusual
               or nonrecurring transactions or events affecting the Company,
               any affiliate of the Company, or the financial statements of the
               Company or any affiliate, or of changes in applicable laws,
               regulations, or accounting principles, the Administrator, in its
               sole and absolute discretion, and on such terms and conditions
               as it deems appropriate, either by the terms of the Option or by
               action taken prior to the occurrence of such transaction or
               event (any such action applied to Employees and former Employees
               to be applied uniformly) and either automatically or upon the
               Holder's request, is hereby authorized to take any one or more
               of the following actions whenever the Administrator determines
               that such action is appropriate in order to prevent dilution or
               enlargement of the benefits or potential benefits intended to be
               made available under the Plan or with respect to any Option
               under the Plan, to facilitate such transactions or events or to

                      such Option for an amount of cash equal to the amount
                      that could have been attained upon the exercise of such
                      Option or realization of the Holder's rights had such
                      Option been currently exercisable or payable or fully
                      vested, or the replacement of such Option with other
                      rights or property selected by the Administrator in its
                      sole discretion;


                           (ii) to provide that the Option cannot vest, be
                      exercised or become payable after such event;

                           (iii)to provide that such Option shall be
                      exercisable as to all shares covered thereby,
                      notwithstanding anything to the contrary in Section 5.3
                      or the provisions of such Option;

                           (iv)to provide that such Option be assumed by the
                      successor or survivor corporation, or a parent or
                      subsidiary thereof, or shall be substituted for by
                      similar options, rights or awards covering the stock of
                      the successor or survivor corporation, or a parent or
                      subsidiary thereof, with appropriate adjustments as to
                      the number and kind of shares and prices;

                            (v)to make adjustments in the number and type of
                      shares of Common Stock (or other securities or property)
                      subject to outstanding Options, and/or in the terms and
                      conditions of (including the grant or exercise price),

<page>


                           (vi)to provide that, for a specified period of time
                      prior to such event, the restrictions imposed under an
                      Option Agreement upon some or all shares of Common Stock
                      may be terminated and some or all shares of such Common
                      Stock may cease  to be subject to repurchase after such
                      event.

                      (c)  Subject to Sections 8.3(d), 3.2 and 3.3, the
               Administrator may, in its discretion, include such further
               provisions and limitations in any Option, Option Agreement or
               certificate, as it may deem equitable and in the best interests
               of the Company.

                      (d) With respect to Options which are granted to
               Section 162(m) Employees and are intended to qualify as
               performance-based compensation under Section 162(m)(4)(C), no
               adjustment or action described in this Section 8.3 or in any
               other provision of the Plan shall be authorized to the extent
               that such adjustment or action would cause such Option to fail
               to so qualify under Section 162(m)(4)(C), or any successor
               provisions thereto.  No adjustment or action described in this
               Section 8.3 or in any other provision of the Plan shall be
               authorized to the extent that such adjustment or action would
               cause the Plan to violate Section 422(b)(1) of the Code.
               Furthermore, no such adjustment or action shall be authorized to
               the extent such adjustment or action would result in short-swing
               profits liability under Section 16 or violate the exemptive
               conditions of Rule 16b-3 unless the Administrator determines
               that the Option is not to comply with such exemptive conditions.
               The number of shares of Common Stock subject to any Option shall
               always be rounded to the next whole number.

                      (e) The existence of the Plan, any Option Agreement
               and the Options granted hereunder shall not affect or restrict
               in any way the right or power of the Company or the stockholders
               of the Company to make or authorize any adjustment,
               recapitalization, reorganization or other change in the
               Company's capital structure or its business, any merger or
               consolidation of the Company, any issue of stock or of options,
               warrants or rights to purchase stock or of bonds, debentures,
               preferred or prior preference stocks whose rights are superior
               to or affect the Common Stock or the rights thereof or which are
               convertible into or exchangeable for Common Stock, or the
               dissolution or liquidation of the Company, or any sale or
               transfer of all or any part of its assets or business, or any
               other corporate act or proceeding, whether of a similar
               character or otherwise.


               8.4  Change in Control. Notwithstanding any other provision
of the Plan, in the event of a Change in Control, each outstanding Option
shall, immediately prior to the effective date of the Change in Control,
automatically become fully exercisable for all of the 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.



              8.5  Approval of Plan by Stockholders. The Plan shall be
submitted for the approval of the Company's stockholders within twelve months
after the date of the Board's initial adoption of the Plan.  Options may be
granted prior to such stockholder approval;

                                       16

<page>

provided, however, that such Options shall not be exercisable nor shall such
Options vest prior to the time when the Plan is approved by the stockholders;
and provided, further, that if such approval has not been obtained at the end
of said twelve-month period, all Options previously granted under the Plan
shall thereupon be canceled and become null and void.


          8.6  Tax Withholding. The Company shall be entitled to require
payment in cash or deduction from other compensation payable to each Holder
of any sums required by federal, state or local tax law to be withheld
with respect to the issuance, vesting, exercise or payment of any Option.


          8.7  Forfeiture Provisions. Subject to the limitations of applicable
law, pursuant to its general authority to determine the terms and conditions
applicable to Options under the Plan, the Administrator shall have the right
to provide, in the terms of Options made under the Plan, or to require a Holder
to agree by separate written instrument, that if (a)(i) the Holder at any time,
or during a specified time period, engages in any activity in competition
with the Company, or which is inimical, contrary or harmful to the interests of
the Company, as further defined by the Administrator or (ii) the Holder incurs
a Termination of Employment for cause, then (b) (i) any proceeds, gains or
other economic benefit actually or constructively received by the Holder upon
any exercise of the Option, or upon the receipt or resale of any Common Stock
underlying any Option, must be paid to the Company, and (ii) the Option shall
terminate and any unexercised portion of the Option (whether or not vested)
shall be forfeited.


          8.8  Effect of Plan upon Options and Compensation Plans. The adoption
of the Plan shall not affect any other compensation or incentive plans in
effect for the Company or any Subsidiary.  Nothing in the Plan shall be
construed to limit the right of the Company (a) to establish any other forms of
incentives or compensation for Employees of the Company or any Subsidiary or
(b) to grant or assume options otherwise than under the Plan in connection with
any proper corporate purpose including but not by way of limitation, the grant
or assumption of options in connection with the acquisition by purchase, lease,
merger, consolidation or otherwise, of the business, stock or assets of any
corporation, partnership, limited liability company, firm or association.



          8.9  Compliance with Laws. The Plan, the granting and vesting of
Options under the Plan and the issuance and delivery of shares of Common Stock
and the payment of money under the Plan or under Options granted hereunder are
subject to compliance with all applicable federal and state laws, rules and
regulations (including but not limited to state and federal securities law and
federal margin requirements) and to such approvals by any listing, regulatory
or governmental authority as may, in the opinion of counsel for the Company,
be necessary or advisable in connection therewith.  Any securities delivered
under the Plan shall be subject to such restrictions, and the person acquiring
such securities shall, if requested by the Company, provide such assurances and
representations to the Company as the Company may deem necessary or desirable
to assure compliance with all applicable legal requirements.  To the extent
permitted by applicable law, the  Plan and Options granted hereunder shall be
deemed amended to the extent necessary to conform to such laws, rules and
regulations.


          8.10 Inability to Obtain Authority. The inability of the Company
to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful

                                       17


<page>

issuance and sale of share of Common Stock hereunder, shall relieve the Company
of any liability in respect of the failure to issue or sell such shares of
Common Stock as to which such requisite authority shall not have been obtained.


          8.11 Reservation of Shares. The Company, during the term of this
Plan, shall at all times reserve and keep available such number of shares of
Common Stock as shall be sufficient to satisfy the requirements of the Plan.


          8.12 Titles. Titles are provided herein for convenience only and
are not to serve as a basis for interpretation or construction of the Plan.


          8.13 Governing Law. The Plan and any agreements hereunder shall be
administered, interpreted and enforced under the internal laws of the State of
Delaware without regard to conflicts of laws thereof.

                                 2003 STOCK OPTION PLAN

                                        APPENDIX
                                       FOR GERMANY


                      1. Application.  This Appendix shall apply only in
          relation to Options granted to eligible Employees residing and
          providing services in Germany.


                      2. Definitions.  Unless otherwise defined herein,
          definitions as set out in Article I of the Plan are applicable to
          this Appendix.


                      3. Eligible Employees.  The Committee's discretion with
          respect to Section 4.4(a)(i) of the Plan will be exercised in a way
          complying with German law, in particular with the labour law
          principle of equal treatment (arbeitsrechtlicher Gleichbehandlungs-
          grundsatz) and with the prohibition of discrimination (Diskriminie-
          rungsverbot).


                      4. Ex-gratia Benefit.  The grant of an Option is an
          ex-gratia benefit (freiwillige Leistung). It is granted without
          any obligation; and even repeated granting will not create such
          obligation.


                      5. Adjustments upon Changes in Capitalization, Merger or
          Asset Sale. The Committee's discretion with respect to any
          adjustments pursuant to  Section 8.3(a) will be exercised taking into
          fair consideration the circumstances why such adjustment is deemed
          appropriate.


                      6. Administrator's Decisions.  The decisions of the
          Committee in connection with any interpretation of the Plan or in any
          dispute relating to an Option or other matters relating to the Plan
          shall be final and conclusive and binding on the relevant parties.
          It may only be revised by competent courts.



                      7. Governing Law.  The Plan shall be governed by and
          construed in accordance with the laws of the State of Delaware but
          mandatory provisions of the laws of Germany may be applied.

          Insurance Contributions or any other federal, state or local tax
          withholding obligation relating to the exercise or acquisition of
          Stock  under an option be satisfied by (in addition to the Company's
          or Subsidiary's right to withhold from any compensation paid or
          payable to the optionee an amount sufficient to satisfy such
          withholding obligations;) the optionee's tender of a cash payment in
          the minimum amount sufficient to satisfy such withholding
          obligations;.

                      1.  Application.  This Appendix shall apply only in
          relation to Options granted to eligible Employees residing and
          providing services in Italy.


                      2.  Definitions.  Unless otherwise defined herein,
          definitions as set out in Article I of the Plan are applicable to
          this Appendix.


                      3. Ownership Limitation.  Options may be granted to
          purchase an  aggregate of shares, including any shares already held,
          owned or possessed by each optionee, not exceeding more than 10% of
          the voting rights in the ordinary shareholders' meeting of the
          Company or more than 10% of the capital or equity of the Company.


                      If an Optionee shall acquire after the date of grant of
          an Option a number of shares that, if added to the number of shares
          under Option, would exceed  more than 10% of the voting rights in
          the ordinary shareholders' meeting of the Company or more than 10% of
          the capital or equity of the Company, he or  she shall immediately
          inform the Company, and the portion of his or her  Option in excess
          of such limits shall not be exercisable. In case of breach of this
          obligation by the Optionee, he or she shall keep the Company and any
          Subsidiary harmless and indemnified from any possible cost incurred
          as  a consequence of the exercise of the portion of Option exceeding
          the above  referred limits.


                      4. Exercise Price.  The exercise price per share of Stock
          shall be not less than the higher of the following amounts:


                          (a)the average of the official stock exchange closing
                      prices of the shares of the class of Stock to which the
                      Option relates, as resulting on each day in which the
                      shares are traded on the market in the period starting
                      from the Date of Grant until the same calendar day of the
                      previous month;

                          (b)the average of the official stock exchange
                      closing prices of the shares of the class of Stock to
                      which the Option relates, as resulting on each day in
                      which the shares are traded on the market in the period
                      starting from the day before the date of grant until the
                      same calendar day of the previous month;


                          (c)the nominal value of the shares of the class of
                      Stock to which the Option relates.


                      5.  Consequences of Exercise.  Any possible positive
          difference between the exercise price per share of Stock paid upon
          the exercise of the Option and the fair market price of those
          shares at that moment and, in general, any and all benefits granted
          to any optionee pursuant to the Plan and this Appendix:

<page>



                           (a)shall be deemed as an extraordinary payment and
               may not,in any way, be considered as a part of the normal
               remuneration of any optionee. In particular, the above mentioned
               positive difference in value shall be considered as already
               including the relevant incidence on the direct or indirect
               income institutions regulated by the collective and individual
               economic agreements in force from time to time such as, by way
               of example, the tredicesima and quattordicesima monthly
               installments and by the law such as, by way of example, the
               severance allowance TFR, the untaken holidays indemnity and
               the indemnity in lieu of notice and shall not, therefore, have
               any further impact on the calculation of the same;

                      4.  Exercise Limitations.  No Option may be exercised
          prior to the expiration of a minimum period of one year following
          the date of grant. In addition, the shares of Stock acquired as a
          result of the exercise of all or part of the Option cannot be
          transferred by an optionee before the expiration of a three-year
          period which shall start running as from the expiration of the
          above mentioned period of one year.


                      5.  Transfer Restrictions.  The shares of Common Stock
          acquired as a result of the exercise of the Option may however be
          immediately transferred upon the occurrence of one of the events
          referred to under Article 91-bis of appendix II to the French General
          Tax Code, i.e., the dismissal, retirement, disability or death of the
          eligible Employee. In case of dismissal or retirement the exception
          to the non-transferability  deadline of the shares of Common Stock
          shall be subject to the condition that the Option shall have been
          exercised at least three months before the dismissal or the
          retirement.



                      6.  Modifications of Exercise Price.  The Option
          exercise price shall be determined on the date of grant.  Any
          adjustment made to the Option exercise price and/or the number of
          Options awarded under this Appendix, shall not provide more
          advantages to the optionee than those which would result from any
          adjustments that would be made in  accordance with the provisions of
          Article L 225-181 of the French business code (Code de Commerce).


                      7.  Payment.  The consideration to be paid for the
          shares of Stock to be issued upon exercise of an Option may consist
          of (1) cash (2) check, or (3) any combination of the foregoing
          methods of payment.


                      8.  Governing Law.  The Plan shall be governed by and
          construed in accordance with the laws of the State of Delaware but
          mandatory provisions of the laws of France may be applied.
