          granted to any Participant in any fiscal year;

          the United States,  or both, on such terms and  conditions,  including
          imposing  conditions  on the  exercise  or Vesting of  Options,  Stock

and conditions shall be made and prescribed in the context of preserving the tax

for any action or  determination  made in good faith with respect to the Plan or
any Option.

Agreement,  Restricted  Stock  Purchase  Agreement  or  Restricted  Stock  Units
Agreement evidencing such Option, Stock Purchase Right or Restricted Stock Unit,
as applicable. ISOs may be granted only to Key Employees.  Non-Qualified Options
may be granted to any Key Employee,  director or consultant of the Company or an
Affiliate.  Stock Purchase  Rights and  Restricted  Stock Units shall be granted
only in connection with the hiring or retention of a Key Employee.  The granting
of any Option,  Stock Purchase Right or Restricted  Stock Unit to any individual
shall  neither  entitle  that  individual  to, nor  disqualify  him or her from,
participation in any other grant of Options, Stock Purchase Rights or Restricted
Stock Unit.

6.   TERMS AND CONDITIONS OF OPTIONS.

     Each  Option  shall be set forth in  writing in an Option  Agreement,  duly
executed by the Company  and, to the extent  required by law or requested by the
Company,  by the  Participant.  The  Administrator  may provide  that Options be
granted  subject  to such terms and  conditions  as the  Administrator  may deem
appropriate   including,   without   limitation,   subsequent  approval  by  the
stockholders of the Company of this Plan or any amendments  thereto.  The Option
Agreements shall be subject to at least the following terms and conditions:

     A.   Non-Qualified  Options:  Each Option  intended  to be a  Non-Qualified
          Option  shall  be  subject  to the  terms  and  conditions  which  the
          Administrator determines to be appropriate and in the best interest of
          the Company,  subject to the following  minimum standards for any such
          Non-Qualified Option:

          a.   Option Price:  The option price (per share) of the Shares covered
               by each Option shall be determined by the Administrator but shall
               not be less than

                                       7



               one hundred  percent  (100%) of the Fair Market Value (per share)
               of the Shares on the date of grant of the Option.

          b.   Each Option  Agreement  shall state the number of Shares to which
               it pertains;

          c.   Each Option  Agreement  shall state the date or dates on which it
               first is exercisable and the date after which it may no longer be
               exercised,  and may provide that the Option rights Vest or become
               exercisable in installments  over a period of months or years, or
               upon the  occurrence of certain  conditions or the  attainment of
               stated goals or events; and

          d.   Exercise of any Option may be conditioned upon the  Participant's
               execution of a stock purchase  agreement in form  satisfactory to
               the  Administrator  providing  for  certain  protections  for the
               Company and its other stockholders, including requirements that:

               i.   The Participant's or the  Participant's  Survivors' right to
                    sell or transfer the Shares may be restricted; and

               ii.  The  Participant  or  the  Participant's  Survivors  may  be
                    required to execute  letters of  investment  intent and must
                    also  acknowledge  that the Shares will bear legends  noting
                    any applicable restrictions.

          e.   Limitation on Grant of  Non-Qualified  Options:  No Non-Qualified
               Option shall be granted  after the date  provided in Paragraph 24
               of this Plan.

          f.   Directors'  Options:  Each  director of the Company who is not an
               employee  of the  Company  or any  Affiliate,  upon  first  being
               elected or appointed to the Board of Directors,  shall be granted
               a  Non-Qualified  Option  to  purchase  8,000  Shares;  provided,
               however,  that the  Administrator  shall be  entitled to grant an
               Option for such higher number of Shares as may be appropriate (as
               determined by the Board of Directors) for  recruitment  purposes.
               Each  director  of the  Company  who is  not an  employee  of the
               Company or any Affiliate on January 18, 2001, shall be granted on
               such date a Non-Qualified  Option to purchase 52,000 Shares as an
               initial grant for joining the Board of Directors.  For the annual
               meeting of stockholders in 2002, on the date following the annual
               meeting of  stockholders  of the  Company,  giving  effect to the
               election of any director or  directors at such annual  meeting of
               stockholders, each director who is not an employee of the Company
               or any  Affiliate  and who has  served at least  six  months as a
               director  shall be  granted a  Non-Qualified  Option to  purchase
               40,000 Shares.  Beginning with the annual meeting of stockholders
               in 2003, on the date following the annual meeting of stockholders
               of the Company  each year,  giving  effect to the election of any
               director or  directors  at such annual  meeting of  stockholders,
               each  director  who is  not an  employee  of

                                       8



               the  Company  or any  Affiliate  and who has  served at least six
               months as a director shall be granted a  Non-Qualified  Option to
               purchase  8,000  Shares.  Each  Option  granted  pursuant to this
               Paragraph  6(A)(f) shall (i) have an exercise  price equal to the
               Fair Market  Value (per share) of the Shares on the date of grant
               of the Option, (ii) have a term of ten (10) years, and (iii) Vest
               in  installments  of 25% annually over a four-year  period and on
               the date of a meeting  of  stockholders  at which  directors  are
               elected if the director does not stand for  re-election or is not
               re-elected at such meeting,  unless a different  vesting schedule
               is established  by the  Administrator  in the  applicable  Option
               Agreement.  The  Board of  Directors  may  amend  this  Paragraph
               6(A)(f) to  increase,  reduce,  eliminate,  or  institute  option
               grants for Board,  Committee or other  individual  or  collective
               service under this Plan.

     B.   ISOs:  Each  Option  intended to be an ISO shall so state and shall be
          issued only to a Key Employee and be subject to at least the following
          terms and conditions,  with such additional restrictions or changes as
          the Administrator  determines are appropriate but not in conflict with
          Section 422 of the Code and  relevant  regulations  and rulings of the
          Internal Revenue Service:

          a.   Minimum  standards:  The ISO  shall  meet the  minimum  standards
               required of Non-Qualified Options, as described in Paragraph 6(A)
               above, except clauses (a) and (f) thereunder.

          b.   Option Price:  Immediately  before the Option is granted,  if the
               Participant  owns,  directly  or  by  reason  of  the  applicable
               attribution rules in Section 424(d) of the Code:

               i.   Ten percent (10%) or less of the total combined voting power
                    of all classes of stock of the Company or an Affiliate,  the
                    Option price per share of the Shares  covered by each Option
                    shall not be less  than one  hundred  percent  (100%) of the
                    Fair Market Value per share of the Shares on the date of the
                    grant of the Option.

               ii.  More than ten  percent  (10%) of the total  combined  voting
                    power  of  all  classes  of  stock  of  the  Company  or  an
                    Affiliate,  the Option price per share of the Shares covered
                    by each  Option  shall  not be less  than  one  hundred  ten
                    percent  (110%)  of the  Fair  Market  Value  on the date of
                    grant.

          c.   Term of Option: For Participants who own

               i.   Ten percent (10%) or less of the total combined voting power
                    of all classes of stock of the Company or an Affiliate, each
                    Option shall  terminate  ten (10) years from the date of the
                    grant or at such  earlier time as the Option  Agreement  may
                    provide.

                                       9



               ii.  More than ten  percent  (10%) of the total  combined  voting
                    power  of  all  classes  of  stock  of  the  Company  or  an
                    Affiliate,  each Option shall  terminate five (5) years from
                    the date of the grant or at such  earlier time as the Option
                    Agreement may provide.

          d.   Limitation  on  Yearly  Exercise:  The  Option  Agreements  shall
               restrict the amount of Options  which may be  exercisable  in any
               calendar year (under this or any other ISO plan of the Company or
               an Affiliate) so that the aggregate Fair Market Value (determined
               at the time each ISO is  granted)  of the stock  with  respect to
               which ISOs are  exercisable for the first time by the Participant
               in any calendar year does not exceed one hundred thousand dollars
               ($100,000),  provided  that this  subparagraph  (d) shall have no
               force or effect if its inclusion in the Plan is not necessary for
               Options  issued as ISOs to  qualify as ISOs  pursuant  to Section
               422(d) of the Code.

          e.   Limitation  on Grant of ISOs:  No ISOs shall be granted after the
               date provided in Paragraph 24 of this Plan.

          f.   To the extent that an Option which is intended to be an ISO fails
               to so qualify, it shall be treated as a Non-Qualified Option.

7.   EXERCISE OF OPTIONS AND ISSUANCE OF SHARES.

     An  Option  (or any part or  installment  thereof)  shall be  exercised  in
accordance with  procedures  established by the Company by giving written notice
to the Company at its principal  executive office address, or such other address
as the Company shall determine,  together with provision for payment of the full
purchase price in accordance  with this Paragraph for the Shares as to which the
Option is being exercised,  and upon compliance with any other  condition(s) set
forth in the Option Agreement. Such written notice shall be signed by the person
exercising  the Option,  shall state the number of Shares with  respect to which
the Option is being exercised and shall contain any  representation  required by
the Plan or the Option  Agreement.  Payment of the purchase price for the Shares
as to which such Option is being  exercised  shall be made (a) in United  States
dollars  in cash or by check,  or (b) at the  discretion  of the  Administrator,
through  delivery of shares of Common  Stock having a Fair Market Value equal as
of the date of the exercise to the cash exercise price of the Option,  or (c) at
the  discretion  of the  Administrator,  by delivery of the  grantee's  personal
recourse  note bearing  interest  payable not less than annually at no less than
100% of the applicable  Federal rate, as defined in Section 1274(d) of the Code,
or (d) at the  discretion of the  Administrator,  in accordance  with a cashless
exercise program  established with a securities  brokerage firm, and approved by
the Administrator,  or (e) at the discretion of the Administrator,  through such
other method of payment approved by the Administrator,  or (f) at the discretion
of the  Administrator,  by any  combination of (a), (b), (c), (d) and (e) above.
Notwithstanding the foregoing,  the Administrator shall accept only such payment
on exercise of an ISO as is permitted by Section 422 of the Code.

     The Company shall then reasonably  promptly  deliver the Shares as to which
such Option was exercised to the Participant (or to the Participant's Survivors,
as the case may be). In

                                       10



determining what constitutes  "reasonably  promptly," it is expressly understood
that the delivery of the Shares may be delayed by the Company in order to comply
with any law or regulation (including,  without limitation,  state securities or
"blue sky" laws) which  requires  the Company to take any action with respect to
the  Shares  prior to their  issuance.  The  Shares  shall,  upon  delivery,  be
evidenced  by  an  appropriate  certificate  or  certificates  for  fully  paid,
non-assessable Shares.

     The  Administrator  shall have the right to accelerate the date of exercise
of any  installment  of any Option;  provided that the  Administrator  shall not
accelerate the exercise date of any installment of any Option granted to any Key
Employee as an ISO (and not  previously  converted into a  Non-Qualified  Option
pursuant to Paragraph 21) if such acceleration  would violate the annual vesting
limitation  contained in Section  422(d) of the Code,  as described in Paragraph
6(B)(d).

     The Administrator may, in its discretion, amend any term or condition of an
outstanding  Option  provided (i) such term or condition as amended is permitted
by the Plan, (ii) if any amendment is materially adverse to the Participant, any
such  amendment  shall be made only with the consent of the  Participant to whom
the Option was  granted,  or in the event of the death of the  Participant,  the
Participant's  Survivors,  and (iii) any such amendment of any ISO shall be made
only after the  Administrator,  after  consulting  with counsel for the Company,
determines  whether such  amendment  would  constitute a  "modification"  of any
Option  which is an ISO (as that term is defined in Section  424(h) of the Code)
or would cause any adverse tax consequences for the holder of such ISO.

8.   RIGHTS AS A STOCKHOLDER.

     No  Participant  to whom an Option has been granted  shall have rights as a
stockholder with respect to any Shares covered by such Option,  except after due
exercise  of the  Option and  tender of the full  purchase  price for the Shares
being  purchased  pursuant  to such  exercise  (and  satisfaction  of such other
conditions for the transfer of Shares as may be required pursuant to the Option)
and  registration  of the Shares in the Company's  share register in the name of
the Participant.  No Participant to whom a Stock Purchase Right has been granted
shall have rights as a  stockholder  with respect to any Shares  covered by such
Stock  Purchase  Right,  except after tender of the full purchase  price for the
Shares  being  purchased  (and  satisfaction  of such other  conditions  for the
transfer of Shares as may be required  pursuant to the Stock Purchase Right) and
registration  of the Shares in the Company's  share  register in the name of the
purchaser.  Once the Stock Purchase Right is exercised, the purchaser shall have
the rights equivalent to those of a stockholder, and shall be a stockholder when
his or her purchase is entered upon the records of the duly authorized  transfer
agent of the Company.  No adjustment  will be made for a dividend or other right
for  which the  record  date is prior to the date the  Stock  Purchase  Right is
exercised,  except as provided in Paragraph 18 of this Plan. No  Participant  to
whom a Restricted Stock Unit has been granted shall have rights as a stockholder
with  respect to any  Shares  covered  by such  Restricted  Stock Unit until the
registration  of the Shares in the Company's  share  register in the name of the
Participant has occurred.

                                       11



9.   ASSIGNABILITY AND  TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS AND
     RESTRICTED STOCK UNITS.

     By its terms,  an Option,  Stock  Purchase  Right or Restricted  Stock Unit
granted to a Participant shall not be transferable by the Participant other than
(i) by will or by the laws of descent  and  distribution,  or (ii) as  otherwise
determined  by  the  Administrator  and  set  forth  in  the  applicable  Option
Agreement,  Restricted  Stock  Purchase  Agreement  or  Restricted  Stock  Units
Agreement.  The designation of a beneficiary of an Option by a Participant shall
not be deemed a transfer prohibited by this Paragraph. Except as provided above,
an Option or Stock Purchase Right shall be exercisable,  and a Restricted  Stock
Unit may be held,  during the Participant's  lifetime,  only by such Participant
(or by his or her legal  representative)  and shall not be assigned,  pledged or
hypothecated in any way (whether by operation of law or otherwise) and shall not
be subject to execution,  attachment or similar process. Any attempted transfer,
assignment,  pledge,  hypothecation  or other  disposition of any Option,  Stock
Purchase  Right or  Restricted  Stock Unit or of any rights  granted  thereunder
contrary  to the  provisions  of this  Plan,  or the levy of any  attachment  or
similar process upon an Option,  Stock Purchase Right or Restricted  Stock Unit,
shall be null and void.

10.  EFFECT  OF  TERMINATION  OF  SERVICE  OTHER  THAN  "FOR  CAUSE" OR DEATH OR
     DISABILITY.

     Except as otherwise  provided in the  pertinent  Option  Agreement,  in the
event  of a  termination  of  service  (whether  as  an  employee,  director  or
consultant)  with  the  Company  or an  Affiliate  before  the  Participant  has
exercised all Options, the following rules apply:

     a.   A Participant who ceases to be an employee,  director or consultant of
          the Company or of an Affiliate (for any reason other than  termination
          "for cause",  Disability,  or death for which events there are special
          rules in Paragraphs  11, 12, and 13,  respectively),  may exercise any
          Option  granted  to  him  or her to the  extent  that  the  Option  is
          exercisable  on the  date of such  termination  of  service,  but only
          within such term as the  Administrator has designated in the pertinent
          Option  Agreement.  An Option that is not  exercisable  on the date of
          termination  of  service  is  canceled  on  such  date  and may not be
          exercised. An Option that is exercisable on the date of termination of
          service,  but not exercised within the term as the  Administrator  has
          designated in the pertinent  Option  Agreement is canceled and may not
          be exercised thereafter.

     b.   Except  as  provided  in  Paragraph  12,  in no  event  may an  Option
          Agreement  provide,  if the Option is intended to be an ISO,  that the
          time  for   exercise  be  later  than  three  (3)  months   after  the
          Participant's termination of employment.

     c.   The provisions of this Paragraph,  and not the provisions of Paragraph
          12 or 13,  shall  apply  to a  Participant  who  subsequently  becomes
          Disabled or dies after the termination of employment,  director status
          or  consultancy,  provided,  however,  in the case of a  Participant's
          Disability or death within three (3) months after the  termination  of
          employment,  director  status or  consultancy,  the Participant or the

                                       12



          Participant's  Survivors  may exercise the Option  within one (1) year
          after the date of the Participant's termination of employment,  but in
          no event after the date of expiration of the term of the Option.

     d.   Notwithstanding  anything  herein to the contrary,  if subsequent to a
          Participant's  termination  of  employment,  termination  of  director
          status or termination of consultancy,  but prior to the exercise of an
          Option,  the  Board of  Directors  determines  that,  either  prior or
          subsequent to the Participant's  termination,  the Participant engaged
          in conduct which would constitute  "cause" (as defined in Paragraph 11
          below),  then such Participant shall forthwith cease to have any right
          to  exercise  any Option,  whether or not such  Option was  previously
          exercisable.

     e.   A Participant to whom an Option has been granted under the Plan who is
          absent  from work with the  Company  or with an  Affiliate  because of
          temporary  disability (any disability other than a permanent and total
          Disability  as defined in  Paragraph 2 hereof),  or who is on leave of
          absence  for any  purpose,  shall  not,  during the period of any such
          absence,  be  deemed,  by  virtue  of  such  absence  alone,  to  have
          terminated   such   Participant's   employment,   director  status  or
          consultancy  with the  Company  or with an  Affiliate,  except  to the
          extent that the  Administrator  so determines as Company  policy or to
          the extent that the Option Agreement may otherwise expressly provide.

     f.   Except  as  required  by law or as set forth in the  pertinent  Option
          Agreement, Options granted under the Plan shall not be affected by any
          change of a  Participant's  status within or among the Company and any
          Affiliates, so long as the Participant continues to be a Key Employee,
          director or consultant of the Company or any Affiliate.

11.  EFFECT OF TERMINATION OF SERVICE "FOR CAUSE".

     Except  as  otherwise  provided  in the  pertinent  Option  Agreement,  the
following  rules apply if the  Participant's  service  (whether as an  employee,
director or  consultant)  with the Company or an  Affiliate  is  terminated  for
"cause"  prior to the time  that all his or her  outstanding  Options  have been
exercised:

     a.   All outstanding and unexercised Options as of the time the Participant
          is  notified  his  or her  service  is  terminated  for  "cause"  will
          immediately be forfeited.

     b.   For  purposes  of this  Plan,  except  as  otherwise  provided  in the
          pertinent Option  Agreement,  Restricted  Stock Purchase  Agreement or
          Restricted  Stock Units  Agreement,  "cause" shall include (and is not
          limited to)  dishonesty  with respect to the Company or any Affiliate,
          insubordination,  substantial  malfeasance  or  non-feasance  of duty,
          unauthorized  disclosure  of  confidential  information,  and  conduct
          substantially  prejudicial  to  the  business  of the  Company  or any
          Affiliate.  The determination of the Administrator as to the existence
          of "cause" will be conclusive on the Participant and the Company.

                                       13



     c.   "Cause"  is not  limited  to events  which  have  occurred  prior to a
          Participant's  termination  of service,  nor is it necessary  that the
          Administrator's finding of "cause" occur prior to termination.  If the
          Administrator determines, subsequent to a Participant's termination of
          service but prior to the  exercise of an Option,  that either prior or
          subsequent to the Participant's termination the Participant engaged in
          conduct which would constitute "cause," then the right to exercise any
          Option is forfeited.

     d.   Any definition in an agreement between the Participant and the Company
          or an Affiliate,  which  contains a conflicting  definition of "cause"
          for   termination  and  which  is  in  effect  at  the  time  of  such
          termination,  shall supersede the definition in this Plan with respect
          to such Participant.

12.  EFFECT OF TERMINATION OF SERVICE FOR DISABILITY.

     Except  as  otherwise  provided  in  the  pertinent  Option  Agreement,   a
Participant  who terminates his or her  employment,  directorship or consultancy
with the Company or an Affiliate by reason of Disability may exercise any Option
granted to such Participant:

     a.   To the  extent  exercisable  but  not  exercised  on the  date of such
          cessation; and

     b.   In the event rights to exercise the Option Vest  periodically,  to the
          extent of a pro rata  portion of any  additional  rights as would have
          Vested  had the  Participant  not  terminated  his or her  employment,
          directorship or consultancy by reason of such Disability, prior to the
          end of the Vesting  period which next ends  following the date of such
          termination.  The proration  shall be based upon the number of days of
          such Vesting period prior to the date of such termination.

     Except as otherwise provided in the pertinent Option Agreement,  a Disabled
Participant  may exercise such rights only within the period ending one (1) year
after the date of the Participant's  termination of employment,  directorship or
consultancy, as the case may be, notwithstanding that the Participant might have
been able to exercise the Option as to some or all of the Shares on a later date
if the  Participant had not become disabled and had continued to be an employee,
director or consultant or, if earlier,  within the originally prescribed term of
the Option.

     The Company shall make the  determination  both of whether  Disability  has
occurred  and  the  date  of  its  occurrence   (unless  a  procedure  for  such
determination  is set forth in another  agreement  between  the Company and such
Participant, in which case such procedure shall be used for such determination).
If  requested,  the  Participant  shall be examined  by a physician  selected or
approved by the Company,  the cost of which examination shall be paid for by the
Company.

                                       14



13.  EFFECT   OF   DEATH   WHILE   AN   EMPLOYEE,    DIRECTOR   OR   CONSULTANT.

     Except as otherwise  provided in the  pertinent  Option  Agreement,  in the
event of the  death of a  Participant  while  the  Participant  is an  employee,
director or  consultant  of the Company or of an  Affiliate,  such Option may be
exercised by the Participant's Survivors:

     a.   To the extent exercisable but not exercised on the date of death; and

     b.   In the event rights to exercise the Option Vest  periodically,  to the
          extent of a pro rata portion of any additional rights which would have
          Vested had the  Participant  not died prior to the end of the  Vesting
          period  which next ends  following  the date of death.  The  proration
          shall be based upon the number of days of such Vesting period prior to
          the Participant's death.

     Except as otherwise  provided in the  pertinent  Option  Agreement,  if the
Participant's  Survivors  wish to  exercise  the  Option,  they  must  take  all
necessary  steps to  exercise  the Option  within one (1) year after the date of
Participant's  termination of employment,  directorship or  consultancy,  as the
case may be,  notwithstanding that the decedent might have been able to exercise
the  Option as to some or all of the Shares on a later date if he or she had not
died and had continued to be an employee, director or consultant or, if earlier,
within the originally prescribed term of the Option.

14.  STOCK PURCHASE RIGHTS.

     a.   Rights to Purchase.  Stock Purchase Rights may be issued either alone,
          in addition to, or in tandem with other awards granted under the Plan.
          After the  Administrator  determines that it will offer Stock Purchase
          Rights  under the Plan,  it shall  advise the offeree in  writing,  by
          means of an  Agreement,  of the  terms,  conditions  and  restrictions
          related to the offer,  including the number of Shares that the offeree
          shall be entitled to  purchase,  the price to be paid (which shall not
          be less than the par value of the  Shares),  and the time within which
          the offeree must accept such offer, which shall in no event exceed six
          (6)  months  from the  date  upon  which  the  Administrator  made the
          determination  to grant the Stock Purchase  Right.  The offer shall be
          accepted by execution of a Restricted Stock Purchase  Agreement in the
          form determined by the Administrator.

     b.   Repurchase Option. Unless the Administrator  determines otherwise, the
          Restricted  Stock  Purchase   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).  The purchase price for Shares
          repurchased  pursuant to the Restricted Stock Purchase Agreement shall
          be the  original  price  paid  by the  purchaser  and  may be  paid by
          cancellation of any indebtedness of the purchaser to the Company.  The
          repurchase   option   shall  lapse  at  a  rate   determined   by  the
          Administrator.

                                       15



     c.   Other  Provisions.  The  Restricted  Stock  Purchase  Agreement  shall
          contain such other terms,  provisions and conditions not  inconsistent
          with the Plan as may be  determined by the  Administrator  in its sole
          discretion.  In addition,  the provisions of Restricted Stock Purchase
          Agreements need not be the same with respect to each purchaser.

15.  RESTRICTED STOCK UNITS.

     a.   Grant. Restricted Stock Units may be granted either alone, in addition
          to, or in tandem with other awards  granted under the Plan.  After the
          Administrator  determines  that it will grant  Restricted  Stock Units
          under the Plan, it shall advise the  Participant in writing,  by means
          of an Agreement,  of the terms, conditions and restrictions related to
          the award,  including the number of Shares  subject to the  Restricted
          Stock Unit.

     b.   Forfeiture Provisions.  Unless the Administrator determines otherwise,
          the Restricted Stock Units Agreement shall provide that the Restricted
          Stock  Unit  shall be  forfeited  upon the  voluntary  or  involuntary
          termination of the  Participant's  employment with the Company for any
          reason (including death or Disability).

     c.   Other  Provisions.  The Restricted Stock Units Agreement shall contain
          such other terms,  provisions and conditions not inconsistent with the
          Plan as may be determined by the Administrator in its sole discretion.
          In addition,  the provisions of Restricted Stock Units Agreements need
          not be the same with respect to each Participant.

16.  PURCHASE FOR INVESTMENT.

     Unless the offering and sale of the Shares to be issued upon the particular
exercise  of or  delivery  pursuant  to  an  Option,  Stock  Purchase  Right  or
Restricted  Stock  Unit  shall  have  been  effectively   registered  under  the
Securities  Act of 1933, as now in force or hereafter  amended (the "1933 Act"),
the Company  shall be under no  obligation  to issue the Shares  covered by such
exercise unless and until the following conditions have been fulfilled:

     a.   The person(s) who exercise(s) or is to receive Shares pursuant to such
          Option, Stock Purchase Right or Restricted Stock Unit shall warrant to
          the Company,  prior to the receipt of such Shares, that such person(s)
          are  acquiring  such  Shares for their own  respective  accounts,  for
          investment,  and not with a view to, or for sale in  connection  with,
          the  distribution  of any such  Shares,  in which event the  person(s)
          acquiring  such  Shares  shall  be  bound  by  the  provisions  of the
          following  legend  which  shall be  endorsed  upon the  certificate(s)
          evidencing  their  Shares  issued  pursuant  to such  exercise of such
          grant:

               "The shares  represented by this  certificate have been taken for
               investment  and they may not be sold or otherwise  transferred by
               any  person,  including

                                       16



               a pledgee,  unless (1) either (a) a  Registration  Statement with
               respect to such shares  shall be effective  under the  Securities
               Act of 1933,  as amended,  or (b) the Company shall have received
               an opinion of counsel  satisfactory  to it that an exemption from
               registration  under  such Act is then  available,  and (2)  there
               shall have been compliance with all applicable  state  securities
               laws."

     b.   At the  discretion  of  the  Administrator,  the  Company  shall  have
          received an opinion of its counsel  that the Shares may be issued upon
          such  particular  exercise  in  compliance  with the 1933 Act  without
          registration thereunder.

     The Company may delay issuance of the Shares until completion of any action
or  obtaining  of any  consent  which  the  Company  deems  necessary  under any
applicable law (including,  without  limitation,  state securities or "blue sky"
laws.)

17.  DISSOLUTION OR LIQUIDATION OF THE COMPANY.

     Upon the  dissolution  or liquidation  of the Company,  all Options,  Stock
Purchase  Rights and Restricted  Stock Units granted under this Plan which as of
such date shall not have been exercised will terminate and become null and void;
provided,  however,  that if the  rights  of a  Participant  or a  Participant's
Survivors have not otherwise  terminated and expired, (i) the Participant or the
Participant's   Survivors  will  have  the  right   immediately  prior  to  such
dissolution or liquidation (A) to exercise any Option or Stock Purchase Right to
the extent that the Option or Stock Purchase Right is exercisable as of the date
immediately  prior to such  dissolution or liquidation and (B) to receive Shares
pursuant to any Vested and  outstanding  Restricted  Stock  Unit;  and (ii) if a
Change in Control shall have occurred within the twelve months immediately prior
to the  date  of such  dissolution  or  liquidation,  such  Participant  or such
Participant's   Survivors  will  have  the  right   immediately  prior  to  such
dissolution  or  liquidation  to exercise any Option,  Stock  Purchase  Right or
receive Shares pursuant to any Restricted Stock Unit then outstanding whether or
not such Option,  Stock Purchase Right or Restricted Stock Unit is Vested and/or
exercisable as of such date.

18.  ADJUSTMENTS.

     Upon the  occurrence of any of the following  events,  the  adjustments  as
hereinafter provided shall be made, unless otherwise  specifically provided in a
pertinent Option  Agreement,  Restricted Stock Purchase  Agreement or Restricted
Stock Units Agreement:

     A. Stock  Dividends  and Stock  Splits.  If (i) the shares of Common  Stock
shall be subdivided or combined into a greater or smaller number of shares or if
the Company  shall issue any shares of Common  Stock as a stock  dividend on its
outstanding  Common Stock, or (ii) additional  shares or new or different shares
or other securities of the Company or other non-cash assets are distributed with
respect to such shares of Common Stock,  the number of Shares  deliverable  upon
the  exercise of an Option or Stock  Purchase  Right or pursuant to a Restricted
Stock Unit may be  appropriately  increased  or decreased  proportionately,  and
appropriate  adjustments  may be made in the purchase price per share to reflect
such subdivision, combination

                                       17



or stock  dividend.  The number of Shares  subject to options to be granted  (i)
pursuant to Paragraph 3 or to directors pursuant to Paragraph 6(A)(f) shall also
be  proportionately  adjusted upon the occurrence of such events,  except as the
Administrator  shall otherwise determine in its sole discretion or (ii) pursuant
to Paragraph 4(c) shall also be proportionately  adjusted upon the occurrence of
such events.

     B.  Corporate  Changes in Control.  In the event of a  Corporate  Change in
Control,

     i. Each Option,  Stock Purchase Right or Restricted  Stock Unit outstanding
as of the date such Corporate  Change in Control is determined to have occurred,
and which is not then  exercisable or Vested by reason of Vesting  requirements,
shall  automatically  accelerate the Vesting so that the Option,  Stock Purchase
Right or Restricted Stock Unit shall become fully Vested and, where  applicable,
shall  become  fully  exercisable  and, in the case of  Restricted  Stock Units,
Shares shall be transferred to the Participant, on the first to occur of (x) the
date the Option,  Stock Purchase  Right or Restricted  Stock Unit becomes Vested
and, if applicable,  exercisable  under its original terms (with respect only to
such Options, Stock Purchase Rights or Restricted Stock Units as otherwise would
Vest during such one-year period under their terms),  (y) the first  anniversary
of the date such Corporate Change in Control is determined to have occurred, and
(z) the occurrence of an Involuntary Employment Action; and

     ii. The Options or Stock  Purchase  Rights so  accelerated  shall remain so
exercisable  until the earlier of the original  expiration date of the Option or
Stock Purchase Right and the earlier termination of the Option or Stock Purchase
Right in accordance with the Plan and the applicable Agreement.

     C. Transactional Changes in Control. In the event of a Transactional Change
in Control,

     i. Each Option,  Stock Purchase Right or Restricted  Stock Unit outstanding
as of the date  such  Transactional  Change in  Control  is  determined  to have
occurred shall be: (a) assumed by the successor  corporation  (or its parent) or
replaced with a comparable option, stock purchase right or restricted stock unit
with respect to shares of the capital stock of the successor corporation (or its
parent)  on an  equitable  basis,  (b)  terminated  upon  written  notice to the
Participants stating that (i), in the case of Options and Stock Purchase Rights,
all such Options or Stock Purchase Rights (for purposes of this Subparagraph all
Options  or  Stock  Purchase  Rights  then  outstanding  shall be  deemed  to be
exercisable)  must be exercised  within a specified  number of days (which shall
not be less  than 15 days)  from the date such  notice  is given,  at the end of
which period the Options or Stock  Purchase  Rights shall  terminate and (ii) in
the case of  Restricted  Stock  Units,  that Shares  shall be  delivered  to the
Participant pursuant to such awards within 15 days after the date such notice is
given,  or (c)  terminated  in exchange for a cash payment  equal to (i), in the
case of Options and Stock Purchase  Rights,  the excess of the Fair Market Value
of the shares subject to such Options or Stock Purchase  Rights (for purposes of
this   Subparagraph  all  Options  then  outstanding   shall  be  deemed  to  be
exercisable)  over the exercise price thereof and (ii) in the case of Restricted
Stock  Units,  the Fair Market  Value of the Shares  subject to such  Restricted
Stock Units.  The  determination of which of the treatments set

                                       18



forth in clauses  (a), (b) and (c) above to provide and of  comparability  under
clause (a) above shall be made by the Administrator and its determinations shall
be final, binding and conclusive.

     ii. The Vesting of each Option,  Stock Purchase  Right or Restricted  Stock
Unit that is assumed or replaced in connection  with a  Transactional  Change in
Control shall automatically  accelerate so that the Option, Stock Purchase Right
or Restricted Stock Unit shall become fully Vested and, where applicable,  shall
become fully  exercisable,  and, in the case of Restricted  Stock Units,  Shares
shall be transferred to the  Participant,  on the first to occur of (x) the date
the Option, Stock Purchase Right or Restricted Stock Unit becomes Vested and, if
applicable,  exercisable  under its  original  terms (with  respect only to such
Options, Stock Purchase Rights or Restricted Stock Units as otherwise would Vest
during such one-year period under their terms), (y) the first anniversary of the
date such  Transactional  Change in Control is determined to have occurred,  and
(z) the occurrence of an  Involuntary  Employment  Action.  The Options or Stock
Purchase Rights so accelerated  shall remain so exercisable until the earlier of
the  original  expiration  date of the  Option or Stock  Purchase  Right and the
earlier termination of the Option or Stock Purchase Right in accordance with the
Plan and the applicable Agreement.

     D. Corporate Transaction. In the event of a Corporate Transaction that does
not  constitute a  Transactional  Change in Control or in the event of a similar
event,  pursuant to which securities of the Company or of another corporation or
entity are issued with  respect to the  outstanding  shares of Common  Stock,  a
Participant upon exercising an Option or Stock Purchase Right or becoming Vested
under a Restricted  Stock Unit shall be entitled to receive  (where  applicable,
for the purchase price paid upon such exercise) the securities  which would have
been received if such Option or Stock Purchase Right had been exercised, or such
Restricted Stock Unit had become Vested, prior to such Corporate Transaction.

     E.  Modification of ISOs.  Notwithstanding  the foregoing,  any adjustments
made pursuant to  Subparagraph  A, B, C, or D with respect to ISOs shall be made
only after the  Administrator,  after  consulting  with counsel for the Company,
determines  whether such adjustments  would constitute a "modification"  of such
ISOs (as that term is defined in Section  424(h) of the Code) or would cause any
adverse  tax  consequences  for the holders of such ISOs.  If the  Administrator
determines that such  adjustments  made with respect to ISOs would  constitute a
"modification" of such ISOs, it may refrain from making such adjustments, unless
the holder of an ISO  specifically  requests in writing that such  adjustment be
made and such  writing  indicates  that the  holder  has full  knowledge  of the
consequences  of such  "modification"  on his or her income tax  treatment  with
respect to the ISO.

19.  ISSUANCES OF SECURITIES.

     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  subject to Options,  Stock  Purchase
Rights or  Restricted  Stock Units.  Except as  expressly  provided  herein,  no
adjustments  shall be made for dividends paid in cash or in property  (including
without limitation, securities) of the Company.

                                       19



20.  FRACTIONAL SHARES.

     No  fractional  shares  shall be  issued  under  the  Plan  and the  person
exercising  such  right  shall  receive  from the  Company  cash in lieu of such
fractional shares equal to the Fair Market Value thereof.

21.  CONVERSION OF ISOs INTO NON-QUALIFIED OPTIONS; TERMINATION OF ISOs.

     The  Administrator,  at the written request of any Participant,  may in its
discretion  take such actions as may be necessary to convert such  Participant's
ISOs (or any  portions  thereof)  that  have not been  exercised  on the date of
conversion  into  Non-Qualified  Options at any time prior to the  expiration of
such ISOs,  regardless of whether the  Participant is an employee of the Company
or an Affiliate at the time of such  conversion.  Such actions may include,  but
not be limited to,  extending the exercise period or reducing the exercise price
of the appropriate installments of such Options. At the time of such conversion,
the  Administrator  (with  the  consent  of the  Participant)  may  impose  such
conditions  on  the  exercise  of the  resulting  Non-Qualified  Options  as the
Administrator  in its discretion may  determine,  provided that such  conditions
shall not be inconsistent with this Plan. Nothing in the Plan shall be deemed to
give any  Participant the right to have such  Participant's  ISOs converted into
Non-Qualified  Options,  and no such conversion shall occur until and unless the
Administrator takes appropriate  action. The Administrator,  with the consent of
the  Participant,  may also  terminate  any portion of any ISO that has not been
exercised at the time of such conversion.

22.  WITHHOLDING.

     In the event that any federal,  state,  or local income  taxes,  employment
taxes,  Federal Insurance  Contributions Act ("F.I.C.A.")  withholdings or other
amounts are required by  applicable  law or  regulation  to be withheld from the
Participant's  salary,  wages  or  other  remuneration  in  connection  with the
exercise of an Option or a  Disqualifying  Disposition  (as defined in Paragraph
23) or the Vesting of Shares  issued  pursuant to Stock  Purchase  Rights or the
delivery of Shares  pursuant to Restricted  Stock Units,  the Company may deduct
from any amounts due to the Participant, such as compensation or reimbursements,
or may require that the  Participant  advance in cash to the Company,  or to any
Affiliate of the Company which employs or employed the  Participant,  the amount
of such withholdings unless a different withholding  arrangement,  including the
use of shares of the Company's  Common Stock or a promissory note, is authorized
by the  Administrator  (and  permitted  by law),  provided,  however,  that with
respect to persons  subject to Section 16 of the 1934 Act, any such  withholding
arrangement shall be in compliance with any applicable  provisions of Rule 16b-3
promulgated  under  Section 16 of the 1934 Act.  For purposes  hereof,  the fair
market value of the shares withheld for purposes of payroll withholding shall be
determined  in the manner  provided in Paragraph 2 above,  as of the most recent
practicable date prior to the date of exercise.  If the fair market value of the
shares withheld is less than the amount of payroll  withholdings  required,  the
Participant  may be required to advance the difference in cash to the Company or
the Affiliate  employer.  The  Administrator in its discretion may condition the
exercise  of an  Option  for  less  than  the  then  Fair  Market  Value  on the
Participant's payment of such additional withholding.

                                       20



23.  NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION.

     Each Key  Employee  who receives an ISO must agree to notify the Company in
writing immediately after the Key Employee makes a Disqualifying  Disposition of
any  shares  acquired  pursuant  to the  exercise  of an  ISO.  A  Disqualifying
Disposition  is any  disposition  (including any sale) of such shares before the
later of (a) two years after the date the Key  Employee  was granted the ISO, or
(b) one year after the date the Key Employee  acquired  Shares by exercising the
ISO.  If the Key  Employee  has died before  such stock is sold,  these  holding
period  requirements  do not apply and no  Disqualifying  Disposition  can occur
thereafter.

24.  TERMINATION OF THE PLAN.

     Unless  sooner  terminated  by the  Board  of  Directors,  the  Plan  shall
terminate  on  October  28,  2009,  and no  Options,  Stock  Purchase  Rights or
Restricted  Stock Units shall thereafter be granted under the Plan. All Options,
Stock Purchase Rights or Restricted  Stock Units granted under the Plan prior to
that date shall remain in effect until such Options,  Stock  Purchase  Rights or
Restricted  Stock Units shall have been  exercised,  paid out or  terminated  in
accordance  with  the  terms  and  provisions  of the  Plan  and the  applicable
Agreements. The Board of Directors may terminate the Plan at any time; provided,
however,  that any such termination will not materially  impair any rights under
any Option, Stock Purchase Right or Restricted Stock Unit theretofore made under
the Plan without the consent of the Participant.

25.  AMENDMENT OF THE PLAN AND AGREEMENTS.

     The Plan may be amended by the  stockholders  of the Company.  The Plan may
also be  amended  by the Board of  Directors  or the  Administrator,  including,
without  limitation,  to the extent  necessary to qualify any or all outstanding
Options  granted  under the Plan or  Options  to be  granted  under the Plan for
favorable  federal  income tax  treatment  (including  deferral of taxation upon
exercise) as may be afforded  incentive  stock  options under Section 422 of the
Code,  for as long as the  Company has a class of stock  registered  pursuant to
Section 12 of the 1934 Act and to the  extent  necessary  to qualify  the shares
issuable  upon exercise of any  outstanding  Options  granted,  or Options to be
granted,  under the Plan for  listing on any  national  securities  exchange  or
quotation in any national automated quotation system of securities dealers.  Any
amendment approved by the Administrator which the Administrator determines is of
a scope that requires  stockholder  approval  shall be subject to obtaining such
stockholder  approval.  Any  modification  or  amendment  of the Plan shall not,
without the consent of a  Participant,  materially  adversely  affect his or her
rights under an Option, Stock Purchase Right or Restricted Stock Unit previously
granted  to him or her.  With  the  consent  of the  Participant  affected,  the
Administrator may amend outstanding Option Agreements, Restricted Stock Purchase
Agreements  or  Restricted  Stock  Units  Agreements  in a manner  which  may be
materially  adverse to the  Participant but which is not  inconsistent  with the
Plan. In the discretion of the  Administrator,  outstanding  Option  Agreements,
Restricted Stock Purchase Agreements or Restricted Stock Units Agreements may be
amended by the Administrator in a manner which is not materially  adverse to the
Participant.

                                       21



26.  EMPLOYMENT OR OTHER RELATIONSHIP.

     Nothing in this Plan or any Option  Agreement,  Restricted  Stock  Purchase
Agreement or  Restricted  Stock Units  Agreement  shall be deemed to prevent the
Company or an Affiliate from terminating the employment, consultancy or director
status of a Participant,  nor to prevent a Participant  from  terminating his or
her own employment,  consultancy or director status or to give any Participant a
right to be  retained  in  employment  or other  service  by the  Company or any
Affiliate for any period of time.

     All  Options,  Stock  Purchase  Rights and  Restricted  Stock  Units  shall
constitute a special incentive payment to the Participant and shall not be taken
into  account  in  computing  the  amount  of  salary  or  compensation  of  the
Participant  for the purpose of  determining  any  benefits  under any  pension,
retirement,  profit-sharing,  bonus, life insurance or other benefit plan of the
Company or under any agreement  between the Company and the Participant,  unless
such plan or agreement specifically provides otherwise.

27.  GOVERNING LAW.

     With respect to Options and Stock Purchase  Rights granted prior to January
18, 2001,  this Plan shall be governed by and construed in  accordance  with the
laws of the State of Delaware,  the Company's state of incorporation and, except
as otherwise  provided in the pertinent  Option  Agreement or  Restricted  Stock
Purchase Agreement, the United States District Court for the Eastern District of
Virginia shall have exclusive  jurisdiction  over any and all disputes between a
Participant  and the Company  related to or arising out of Options or Restricted
Stock Purchase  Rights granted under this Plan.  With respect to Options,  Stock
