     (a)  Procedure.

          (i)  Multiple  Administrative  Bodies. The Plan may be administered by
               different   Committees  with  respect  to  different   groups  of
               Employees and  Consultants.  (ii) Section  162(m).  To the extent
               that the  Administrator  determines it to be desirable to qualify
               Options  granted  hereunder as  "performance-based  compensation"
               within the meaning of Section  162(m) of the Code, the Plan shall
               be administered by a Committee of two or more "outside directors"
               within the meaning of Section 162(m) of the Code.

          (iii)Rule  16b-3.  To the extent  desirable  to  qualify  transactions
               hereunder   as  exempt   under  Rule  16b-3,   the   transactions
               contemplated   hereunder  shall  be  structured  to  satisfy  the
               requirements for exemption under Rule 16b-3.

          (iv) Other  Administration.  Other than as  provided  above,  the Plan
               shall be administered by (A) the Board or (B) a Committee,  which
               committee shall be constituted to satisfy applicable laws.

     (b)  Powers of the Board.  Subject to the provisions of the Plan, the Board
          shall have the authority, in its discretion:

          (i)  to grant Incentive Stock Options,  Nonstatutory  Stock Options or
               Stock Purchase Rights;

          (ii) to  determine,   upon  review  of  relevant  information  and  in
               accordance  with Section 7 of the Plan,  the fair market value of
               the Common Stock;

          (iii)to  determine  the  exercise  price per share of Options or Stock
               Purchase  Rights,  to be granted,  which  exercise price shall be
               determined in accordance with Section 7 of the Plan;

          (iv) to determine the Employees or  Consultants  to whom, and the time
               or times at which,  Options  or Stock  Purchase  Rights  shall be
               granted and the number of shares to be represented by each Option
               or Stock Purchase Right;

          (v)  to interpret the Plan;

          (vi) to prescribe, amend and rescind rules and regulations relating to
               the Plan;

          (vii)to determine  the terms and  provisions  of each Option and Stock
               Purchase  Right granted  (which need not be identical)  and, with
               the consent of the holder thereof, modify or amend any provisions
               (including  provisions  relating to exercise price) of any Option
               or Stock Purchase Right;

          (viii) to  accelerate  or defer (with the consent of the Optionee) the
               exercise date of any Option,  consistent  with the  provisions of
               Section 5 of the Plan;

          (ix) to  authorize  any person to execute on behalf of the Company any
               instrument required to effectuate the grant of an Option or Stock
               Purchase Right previously granted by the Board;

          (x)  to allow  Optionees to satisfy  withholding  tax  obligations  by
               electing  to have the  Company  withhold  from the  Shares  to be
               issued upon  exercise of an Option or Stock  Purchase  Right that
               number of Shares  having a Fair Market  Value equal to the amount
               required to be  withheld.  The Fair Market Value of the Shares to
               be withheld  shall be  determined  on the date that the amount of
               tax to be  withheld  is to be  determined.  All  elections  by an
               Optionee to have Shares  withheld for this purpose  shall be made
               in such form and under such conditions as the  Administrator  may
               deem necessary or advisable; and

          (xi) to make all other  determinations  deemed  necessary or advisable
               for the administration of the Plan.

     (c)  Effect  of  Board's  Decision.   All  decisions,   determinations  and
          interpretations  of the  Board  shall  be  final  and  binding  on all
          Optionees,  Purchasers  and any other  holders of any Options or Stock
          Purchase Rights granted under the Plan.

5.   Eligibility.

     (a)  Options  and Stock  Purchase  Rights may be granted to  Employees  and
          Consultants, provided that Incentive Stock Options may only be granted
          to Employees. An Employee or Consultant who has been granted an Option
          or Stock  Purchase  Right  may,  if such  Employee  or  Consultant  is
          otherwise eligible,  be granted additional Option(s) or Stock Purchase
          Right(s).

     (b)  Each Option shall be  designated  in the written  option  agreement as
          either an  Incentive  Stock  Option or a  Nonstatutory  Stock  Option.
          However,  notwithstanding  such  designation,  to the extent  that the
          aggregate  fair  market  value of the  Shares  with  respect  to which
          Options  designated as Incentive Stock Options are exercisable for the
          first time by any Optionee  during any calendar  year (under all plans
          of the Company)  exceeds  $100,000,  such Options  shall be treated as
          Nonstatutory Stock Options.

     (c)  For purposes of Section  5(b),  Options shall be taken into account in
          the order in which they were granted, and the fair market value of the
          Shares shall be  determined  as of the time the Option with respect to
          such Shares is granted.

     (d)  The Plan  shall  not  confer  upon any  Optionee  or holder of a Stock
          Purchase Right any right with respect to continuation of employment by
          or the rendition of consulting  services to the Company,  nor shall it
          interfere in any way with his or her right or the  Company's  right to
          terminate  his or her  employment  or  services  at any time,  with or
          without cause.

     (e)  The  following  limitations  shall  apply  to  grants  of  Options  to
          Employees:

          (i)  No Employee shall be granted,  in any fiscal year of the Company,
               Options to purchase more than 250,000 Shares.

          (ii) In connection with his or her initial employment, an Employee may
               be granted Options to purchase up to an additional 250,000 Shares
               which shall not count  against the limit set forth in  subsection
               (i) above.


          (iii)The foregoing  limitations shall be adjusted  proportionately  in
               connection  with any change in the  Company's  capitalization  as
               described in Section 11.

          (iv) If an Option is  canceled  in the same fiscal year of the Company
               in  which  it  was  granted  (other  than  in  connection  with a
               transaction  described in Section 12), the canceled  Option shall
               be counted  against the limit set forth in subsection  (i) above.
               For this purpose,  if the exercise price of an Option is reduced,
               such reduction  will be treated as a  cancellation  of the Option
               and the grant of a new Option.

6.   Term of Plan. The Plan shall become  effective upon the earlier to occur of
     its  adoption by the Board of  Directors or its approval by vote of holders
     of a majority of the outstanding  shares of the Company entitled to vote on
     the  adoption  of the Plan.  It shall  continue in effect for a term of ten
     (10) years unless sooner terminated under Section 13 of the Plan.

7.   Exercise Price and Consideration.

     (a)  The per Share exercise  price for the Shares to be issued  pursuant to
          exercise of an Option or Stock  Purchase  Right shall be such price as
          is determined by the Board, but shall be subject to the following:

          (i)  In the case of an  Incentive  Stock  Option;  (A)  granted  to an
               Employee  who,  at the  time of  grant  of such  Incentive  Stock
               Option,  owns stock  representing  more than ten percent (10%) of
               the voting  power of all  classes of stock of the  Company or any
               Parent or  Subsidiary,  the per Share  exercise price shall be no
               less than 110% of the fair market  value per Share on the date of
               grant. (B) granted to any other Employee,  the per Share exercise
               price  shall be no less  than 100% of the fair  market  value per
               Share on the date of grant.

          (ii) In the case of a  Nonstatutory  Stock Option or a Stock  Purchase
               Right,  the per Share exercise price shall be no less than 85% of
               the fair market value per Share on the date of grant. In the case
               of  a   Nonstatutory   Stock   Option   intended  to  qualify  as
               "performance-based  compensation"  within the  meaning of Section
               162(m) of the Code, the per Share exercise price shall be no less
               than  100% of the  Fair  Market  Value  per  Share on the date of
               grant.

          (iii)Notwithstanding the foregoing,  Options may be granted with a per
               Share  exercise  price of less than 100% of the Fair Market Value
               per  Share  on the date of grant  pursuant  to a merger  or other
               corporate transaction.

               For purposes of this Section 7(a), in the event that an Option or
          Stock Purchase Right is amended to reduce the exercise price, the date
          of grant of such Option or Stock  Purchase  Right shall  thereafter be
          considered to be the date of such amendment.

     (b)  The  fair  market  value  shall  be  determined  by the  Board  in its
          discretion; provided, however, that where there is a public market for
          the Common Stock, the fair market value per Share shall be the mean of
          the bid and asked prices (or the closing price per share if the Common
          Stock is listed on the  National  Association  of  Securities  Dealers
          Automated  Quotation  ("NASDAQ") National Market System) of the Common
          Stock for the date of grant,  as reported  in the Wall Street  Journal
          (or, if not so reported,  as otherwise  reported by the NASDAQ System)
          or, in the event the Common Stock is listed on a stock  exchange,  the
          fair  market  value  per  Share  shall  be the  closing  price on such
          exchange on the date of grant of the Option or Stock  Purchase  Right,
          as reported in the Wall Street Journal.

     (c)  The consideration to be paid for the Shares to be issued upon exercise
          of an Option or Stock Purchase Right, including the method of payment,
          shall be  determined  by the  Board  (and in the case of an  Incentive
          Stock  Option,  shall  be  determined  at the time of  grant)  and may
          consist  entirely of cash,  check,  promissory  note,  other Shares of
          Common Stock which

          (i)  either  have  been  owned by the  Optionee  for more than six (6)
               months on the date of surrender or were not acquired  directly or
               indirectly, from the Company, and

          (ii) have a fair market  value on the date of  surrender  equal to the
               aggregate  exercise  price of the Shares as to which said  Option
               shall  be  exercised,  or any  combination  of  such  methods  of
               payment,  or such other  consideration  and method of payment for
               the issuance of Shares to the extent permitted under Sections 408
               and 409 of the California General  Corporation Law. In making its
               determination  as to the type of  consideration  to  accept,  the
               Board shall consider if acceptance of such  consideration  may be
               reasonably expected to benefit the Company (Section 315(b) of the
               California General Corporation Law).

8.   Options.

     (a)  Term of Option.  The term of each  Option  shall be the term stated in
          the Option  Agreement;  provided,  however,  that the term shall be no
          more than ten (10) years from the date of grant  thereof.  In the case
          of an Incentive  Stock Option  granted to an Optionee who, at the time
          the Option is granted,  owns stock  representing more than ten percent
          (10%) of the voting  power of all  classes of stock of the  Company or
          any Parent or  Subsidiary,  the term of the  Option  shall be five (5)
          years from the date of grant  thereof or such  shorter  term as may be
          provided in the Option Agreement.

     (b)  Exercise of Option.

          (i)  Procedure  for  Exercise;  Rights as a  Shareholder.  Any  Option
               granted  hereunder  shall be  exercisable at such times and under
               such conditions as determined by the Board, including performance
               criteria with respect to the Company and/or the Optionee,  and as
               shall be permissible  under the terms of the Plan, but in no case
               at a rate of less than 20% per year over five (5) years  from the
               date the Option is granted.

               An Option may not be exercised for a fraction of a Share.

                    An  Option  shall be  deemed to be  exercised  when  written
               notice  of  such  exercise  has  been  given  to the  Company  in
               accordance with the terms of the Option by the person entitled to
               exercise  the Option and full payment for the Shares with respect
               to  which  the  Option  is  exercised  has been  received  by the
               Company. Full payment may, as authorized by the Board, consist of
               any consideration and method of payment allowable under Section 7
               of, the Plan. Until the issuance (as evidenced by the appropriate
               entry  on the  books  of  the  Company  or of a  duly  authorized
               transfer   agent  of  the  Company)  of  the  stock   certificate
               evidencing  such Shares no right to vote or receive  dividends or
               any other rights as a shareholder shall exist with respect to the
               Optioned Sock,  notwithstanding  the exercise of the Option.  The
               Company   shall  issue  (or  cause  to  be  issued)   such  stock
               certificate  promptly upon  exercise of the Option.  In the event
               that the  exercise of a  Nonstatutory  Stock  Option  pursuant to
               Section  5(b),   the  Company   shall  issue  a  separate   stock
               certificate  evidencing  the  Shares  treated  as  acquired  upon
               exercise  of an  Incentive  Stock  Option  and a  separate  stock
               certificate  evidencing  the  Shares  treated  as  acquired  upon
               exercise of a  Nonstatutory  Stock Option and shall identify each
               such certificate  accordingly in its stock transfer  records.  No
               adjustment  will be made for a dividend  or other right for which
               the  record  date is prior to the date the stock  certificate  is
               issued, except as provided in Section 11 of the Plan.

                    Exercise  of an  Option  in any  manner  shall  result  in a
               decrease  in  the  number  of  Shares  which  thereafter  may  be
               available,  both for  purposes of the Plan and for sale under the
               Option,  by the  number  of  Shares  as to which  the  Option  is
               exercised.

          (ii) Termination of Status as an Employee or Consultant.  In the event
               of termination of an Optionee's  Continuous Status as an Employee
               or  Consultant  (as the case may be), such Optionee may, but only
               within such period of time as is  determined  by the Board,  with
               such  determination  in the case of an Incentive Stock Option not
               exceeding three (3) months and in the case of Nonstatutory  Stock
               Option  not   exceeding   six  (6)  months   after  the  date  of
               termination,  with such determination in the case of an Incentive
               Stock  Option  being  made at the time of  grant  of the  Option,
               exercise  the  Option  to  the  extent  that  such   Employee  or
               Consultant  was  entitled  to  exercise  it at the  date  of such
               termination (but in no event later than the date of expiration of
               the term of such Option as set forth in the Option Agreement). To
               the extent that such Employee or  Consultant  was not entitled to
               exercise the Option at the date of such  termination,  or if such
               Employee or Consultant  does not exercise such Option (which such
               Employee or Consultant was entitled to exercise)  within the time
               specified herein, the Option shall terminate.

          (iii)Disability  of  Optionee.   Notwithstanding   the  provisions  of
               Section  8(b)(ii)  above,  in  the  event  of  termination  of an
               Optionee's  Continuous  Status as an Employee or  Consultant as a
               result of such  Employee's  or  Consultant's  total and permanent
               disability  (as defined in Section  22(e)(3)  of the Code),  such
               Employee or  Consultant  may,  but only within six (6) months (or
               such other period of time not exceeding  twelve (12) months as in
               determined by the Board,  with such  determination in the case of
               an  Incentive  Stock Option being made at the time of gant of the
               Option) from the date of such  termination (but in no event later
               than the date of  expiration  of the term of such  Option  as set
               forth in the Option Agreement), exercise the Option to the extent
               such  Employee or  Consultant  was entitled to exercise it at the
               date of such  termination.  To the extent  that such  Employee or
               Consultant was not entitled to exercise the Option at the date of
               termination,  or if such Employee or Consultant does not exercise
               such Option (which such  Employee or  Consultant  was entitled to
               exercise)  within the time  specified  herein,  the Option  shall
               terminate.

          (iv) Death of Optionee. In the event of the death of an Optionee:

               (A)  during  the term of the  Option who is at the time of his or
                    her death an Employee or  Consultant  of the Company and who
                    shall  have  been in  Continuous  Status as an  Employee  or
                    Consultant since the date of grant of the Option, the Option
                    may be exercised,  at any time within six (6) months (but in
                    no event  later than the date of  expiration  of the term of
                    such  Option as set forth in the Option  Agreement),  by the
                    Optionee's  estate or by a person who  acquired the right to
                    exercise the Option by bequest or  inheritance,  but only to
                    the extent that the right to exercise would have accrued had
                    the Optionee  continued  living and  remained in  Continuous
                    Status as an Employee or Consultant  six (6) months (or such
                    other  period of time as in  determined  by the Board at the
                    time of grant of the Option) after the date of death; or

               (B)  within  thirty  (30) days (or such other  period of time not
                    exceeding  three (3) months as is  determined  by the Board,
                    with such  determination  in the case of an Incentive  Stock
                    Option being made at the time of grant of the Option)  after
                    the  termination  of  Continuous  Status as an  Employee  or
                    Consultant,  the Option may be exercised, at any time within
                    six  (6)  months  (or  such  other  period  of  time  as  is
                    determined  by the Board at the time of grant of the Option)
                    following  the date of death (but in no event later than the
                    date of  expiration  of the term of such Option as set forth
                    in the Option  Agreement),  by the Optionee's estate or by a
                    person  who  acquired  the right to  exercise  the Option by
                    bequest or inheritance,  but only to the extent of the right
                    to exercise that had accrued at the date of termination.

9.   Stock Purchase Rights.

     (a)  Rights to Purchase.  After the Board of Directors  determines  that it
          will offer an Employee or Consultant a Stock Purchase  Right, it shall
          deliver  to the  offeree a stock  purchase  agreement  or stock  bonus
          agreement, as the case may be, setting forth the terms, conditions and
          restrictions  relating  to the offer,  including  the number of Shares
          which such person shall be entitled to  purchase,  and the time within
          which such person  must  accept  such  offer,  which shall in no event
          exceed six (6) months from the date upon which the Board of  Directors
          or its Committee  made the  determination  to grant the Stock Purchase
          Right.  The offer shall be accepted by execution  of a stock  purchase
          agreement or stock bonus agreement in the from determined by the Board
          of Directors.

     (b)  Issuance  of Shares.  Forthwith  after  payment  therefor,  the Shares
          purchased shall be duly issued; provided,  however, that the Board may
          require that the Purchaser make adequate provision for any Federal and
          State  withholding  obligations  of the Company as a condition  to the
          Purchaser purchasing such Shares.

     (c)  Repurchase Option.  Unless the Board determines  otherwise,  the stock
          purchase  agreement or stock bonus agreement shall grant the Company a
          repurchase  option  exercisable  upon  the  voluntary  or  involuntary
          termination  of the  Purchaser's  employment  with the Company for any
          reason  (including  death or disability).  If the Board so determines,
          the purchase price for shares  repurchased may be paid by cancellation
          of any  indebtedness  of the Purchaser to the Company.  The repurchase
          option shall lapse at such rate as the Board may determine.

     (d)  Other  Provisions.   The  stock  purchase  agreement  or  stock  bonus
          agreement  shall contain such other terms,  provisions  and conditions
          not  inconsistent  with the Plan as may be  determined by the Board of
          Directors.

10.  Non-Transferability of Options and Stock Purchase Rights. Unless determined
     otherwise by the  Administrator,  an Option or Stock Purchase Right may not
     be sold, pledged, assigned,  hypothecated,  transferred,  or disposed of in
     any manner other than by will or by the laws of descent or distribution and
     may be  exercised,  during  the  lifetime  of  the  Optionee,  only  by the
     Optionee.  If the  Administrator  makes an Option or Stock  Purchase  Right
     transferable,  such  Option or Stock  Purchase  Right  shall  contain  such
     additional terms and conditions as the Administrator deems appropriate.

11.  Adjustments upon Changes in Capitalization or Merger.

     (a)  Changes  in  Capitalization.  Subject  to any  required  action by the
          shareholders  of the  Company,  the  number of shares of Common  Stock
          covered by each  outstanding  Option or Stock Purchase Right,  and the
          number of  shares  of Common  Stock  which  have been  authorized  for
          issuance  under the Plan but as to which no Options or Stock  Purchase
          Rights have yet been  granted or which have been  returned to the Plan
          upon  cancellation or expiration of an Option or Stock Purchase Right,
          as well as the price per share of Common  Stock  covered  by each such
          outstanding  Option or Stock Purchase Right,  shall be proportionately
          adjusted for any  increase or decrease in the number of issued  shares
          of Common Stock  resulting  from a stock split,  reverse  stock split,
          stock dividend,  combination or  reclassification of the Common Stock,
          or any other  increase or  decrease in the number of issued  shares of
          Common Stock effected without receipt of consideration by the Company.
          The conversion of any convertible  securities of the Company shall not
          be deemed to have been "effected  without  receipt of  consideration."
          Such adjustment  shall be made by the Board,  whose  determination  in
          that  respect  shall be  final,  binding  and  conclusive.  Except  as
          expressly  provided  herein,  no  issuance by the Company of shares of
          stock of any class, or securities  convertible into shares of stock of
          any class,  shall affect, and no adjustment by reason thereof shall be
          made with  respect  to, the number or price of shares of Common  Stock
          subject to an Option or Stock Purchase Right.

     (b)  Dissolution or Liquidation.  In the event of the proposed  dissolution
          or  liquidation  of the Company,  the  Administrator  shall notify the
          Optionee  or  Purchaser  at  least  fifteen  (15)  days  prior to such
          proposed action.  To the extent it has not been previously  exercised,
          the Option or Stock Purchase Right shall terminate  immediately  prior
          to the consummation of such proposed action.

     (c)  Merger  or  Asset  Sale.  In the  event  of a  merger,  sale of all or
          substantially all of the assets of the Company,  tender offer or other
          transaction or series of related transactions resulting in a change of
          ownership  of more than 50% of the voting  securities  of the  Company
          ("Change in Control"),  approved by the majority of the members of the
          Board  on the  Board  prior  to the  commencement  of such  Change  in
          Control,  each  outstanding  Option shall be assumed or an  equivalent
          option or right  substituted by the successor  corporation or a Parent
          or Subsidiary of the successor  corporation;  provided however, in the
          event that within one year of the date of the completion of the Change
          in Control, the successor corporation or a Parent or Subsidiary of the
          successor corporation terminates the employment of an Optionee without
          Cause (as defined  below),  such Optionee shall fully vest in and have
          the right to  exercise  the  options  assumed or  substituted  for the
          Option as to all of the Optioned Stock,  including  Shares as to which
          it would not otherwise be exercisable. In the event that the successor
          corporation  refuses  to  assume or  substitute  for the  Option,  the
          Optionee shall fully vest in and have the right to exercise the Option
          as to all of the Optioned Stock, including Shares as to which it would
          not otherwise be  exercisable.  If an Option  becomes fully vested and
          exercisable  in lieu of assumption or  substitution  in the event of a
          Change of Control,  the  Administrator  shall  notify the  Optionee in
          writing or  electronically  that the Option  shall be fully vested and
          exercisable  for a period of  fifteen  (15) days from the date of such
          notice,  and the Option shall  terminate  upon the  expiration of such
          period.  For the  purposes  of this  paragraph,  the  Option  shall be
          considered  assumed if,  following  the Change of Control,  the option
          confers  the  right to  purchase,  for each  Share of  Optioned  Stock
          subject to the Option immediately prior to the Change in Control,  the
          consideration  (whether stock,  cash, or other securities or property)
          received in the Change of Control by holders of Common  Stock for each
          Share held on the effective  date of the  transaction  (and if holders
          were  offered a choice  of  consideration,  the type of  consideration
          chosen  by the  holders  of a  majority  of the  outstanding  Shares);
          provided,  however, that if such consideration  received in the Change
          of Control is not solely common stock of the successor  corporation or
          its Parent,  the Administrator  may, with the consent of the successor
          corporation,  provide for the  consideration  to be received  upon the
          exercise of the Option,  for each Share of Optioned  Stock  subject to
          the Option, to be solely common stock of the successor  corporation or
          its Parent equal in fair market  value to the per share  consideration
          received  by holders of Common  Stock in the  Change of  Control.  For
          purposes of this  paragraph,  termination  shall be for "Cause" in the
          event of the occurrence of any of the following:  (a) any  intentional
          action or  intentional  failure to act by employee which was performed
          in  bad  faith  and  to  the  material   detriment  of  the  successor
          corporation  or its Parent or Subsidiary;  (b) employee  willfully and
          habitually  neglects  the duties of  employment;  or (c)  employee  is
          convicted of a felony crime involving moral  turpitude,  provided that
          in the event  that any of the  foregoing  events is  capable  of being
          cured,  the successor  corporation  or its Parent or Subsidiary  shall
          provide  written notice to the employee  describing the nature of such
          event and the employee shall thereafter have five (5) business days to
          cure such event.

               In the event of a Change in Control  which is not approved by the
          majority  of the  members  of the  Board  on the  Board  prior  to the
          commencement of a Change in Control, each Optionee shall fully vest in
          and have the right to exercise  all  outstanding  Options as to all of
          the  Optioned  Stock,  including  Shares  as to  which  it  would  not
          otherwise be exercisable.

12.  Date of Granting Options.  The date of grant of an Option or Stock Purchase
     Right  shall,  for all  purposes,  be the date on which the Board makes the
     determination  granting such Option or stock Purchase Right.  Notice of the
     determination  shall be given to each  Employee  or  Consultant  to whom an
     Option or Stock Purchase Right is so granted within a reasonable time after
     the date of such grant.

13.  Amendment and Termination of the Plan.

     (a)  Amendment and Termination.  The  Administrator  may at any time amend,
          alter, suspend or discontinue the Plan, but no amendment,  alteration,
          suspension  or  discontinuation  shall be made which would  impair the
          rights of any Optionee under any grant theretofore  made,  without his
          or her consent. In addition,  to the extent necessary and desirable to
          comply with Section 422 of the Code (or any other  Applicable  Laws or
          regulation,  the  requirements  of the  NASD or an  established  stock
          exchange),  the Company shall obtain shareholder  approval of any Plan
          amendment in such a manner and to such a degree as required.

     (b)  Effect of Amendment or Termination.  Any such amendment or termination
          of the Plan shall not affect Options or Stock Purchase  Rights already
          granted,  and such Options and Stock  Purchase  Rights shall remain in
          full  force  and  effect  as if this  Plan  had not  been  amended  or
          terminated,  unless mutually agreed otherwise between the Optionee and
          the  Administrator,  which  agreement must be in writing and signed by
          the Optionee and the Company.

14.  Conditions Upon Issuance of Shares.  Shares shall not be issued pursuant to
     the exercise of an Option or Stock  Purchase  Rights unless the exercise of
     such Option or Stock Purchase  Rights and the issuance and delivery of such
     Shares pursuant  thereto shall comply with all relevant  provisions of law,
     including,  without limitation, the Securities Act of 1933, as amended, the
     Exchange Act, the rules and  regulations  promulgated  thereunder,  and the
     requirements  of any  stock  exchange  upon  which the  Shares  may then be
     listed,  and shall be further  subject to the  approval  of counsel for the
     Company with respect to such compliance.

          As a condition to the exercise of an Option or Stock  Purchase  Right,
     the Company may require the person exercising such Option or Stock Purchase
     Right to represent  and warrant at the time of any such  exercise  that the
     Shares are being  purchased  only for  investment  and  without any present
     intention to sell or  distribute  such Shares if, in the opinion of counsel
     for  the  Company,  such  a  representation  is  required  by  any  of  the
     aforementioned relevant provisions of law.

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

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

16.  Option,  Stock  Purchase  and  Stock  Bonus  Agreements.  Options  shall be
     evidenced  by written  option  agreements  in such form as the Board  shall
     approve.  Upon the exercise of Stock Purchase  Rights,  the Purchaser shall
     sign a stock  purchase  agreement or stock bonus  agreement in such form as
     the Board shall approve.

17.  Shareholder Approval.  Continuance of the Plan shall be subject to approval
     by the  shareholders  of the Company  within  twelve (12) months  before or
     after the date the Plan is  adopted.  Such  shareholder  approval  shall be
     obtained in the degree and manner  required under  Applicable  Laws and the
     rules of any stock exchange upon which the Common Stock is listed.

18.  Information to Optionees and Purchasers.  The Company shall provide to each
     Optionee  and  Purchaser,  during the period  for which  such  Optionee  or
     Purchaser has one or more Options to Stock Purchase Rights  outstanding,  a
     balance sheet and an income statement at least annually.  The Company shall
     not be required to provide such  information to key employees  whose duties
     in  connection   with  the  Company   assure  there  access  to  equivalent
     information.
