II.      AGREEMENT

         1. Grant of Option. The Company hereby grants to the Optionee an option
(the  "Option")  to  purchase  the  number of Shares  set forth in the Notice of
Grant,  at the  exercise  price per share set forth in the  Notice of Grant (the
"Exercise  Price").  In the event of a conflict between the terms and conditions
of the Plan and of this Option  Agreement,  the terms and conditions of the Plan
shall prevail.

            If designated  in the Notice of Grant as an Incentive  Stock Option,
this Option is intended to qualify as an Incentive  Stock  Option under  Section
422 of the Internal Revenue Code (the "Code") of the United States.

         2. Exercise of Option.

            (a) Right to Exercise. This Option is exercisable during its term in
accordance  with the Vesting  Schedule  set forth in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

            (b) Method of Exercise. This Option is exercisable by delivery of an
exercise  notice in the form  attached  as  Exhibit A (the  "Exercise  Notice"),
stating the  election to exercise  the Option,  the number of Shares as to which
the  Option  is  being  exercised  (the  "Exercised  Shares"),  and  such  other
representations and agreements as may be required by the Company pursuant to the
Plan. The Exercise Notice shall be signed by the Optionee and shall be delivered
in person, by certified mail or by fax to the Stockholder  Services  department.
The Exercise  Notice shall be accompanied  by payment of the aggregate  Exercise
Price as to all  Exercised  Shares.  This Option shall be deemed to be exercised
upon receipt by the Company of the fully executed Exercise Notice accompanied by
the aggregate Exercise Price.

            This Option is also exercisable  electronically in a manner approved
by the Administrator. An Exercise Notice is not required for online transactions
provided  that a notice  of  exercise  waiver  is  signed  and  returned  to the
Stockholder Services department before online transactions are performed.

            No Shares  shall be issued upon the  exercise of this Option  unless
such exercise and issuance  complies with all laws and the  requirements  of any
stock  exchange  or  quotation  service  upon which the Shares are then  listed.
Assuming such compliance,  for income tax purposes the Exercised Shares shall be
considered issued on the date the Option is exercised.

            (c)  Restrictions  on Exercise.  This Option may not be exercised if
the  issuance  of such  Shares  upon such  exercise  or the method of payment of
consideration  for such shares would  constitute  a violation of any  applicable
federal or state securities or other law or regulation, including any rule under
Part  207 of Title 12 of the Code of  Federal  Regulations  ("Regulation  G") as
promulgated by the Federal Reserve Board. As a condition to the exercise of this
Option, the Company may require Optionee to make any representation and warranty
to the Company as may be required by any applicable law or regulation.

         3. Method of Payment.  The Administrator shall determine the acceptable
form of consideration for exercising an Option, including method of payment. The
Administrator  shall determine the acceptable form of  consideration at the time
of grant. Such consideration may consist entirely of:

            (a)  cash; or

            (b)  check; or

            (c)  cash  exercise,   cashless  exercise   (same-day-sale),   or  a
                 combination  of both through a broker or an  electronic  manner
                 approved by the Administrator.

         4. Non-Transferability of Option. This Option may not be transferred in
any manner other than by will or by the laws of descent or distribution, and may
be exercised during the lifetime of Optionee only by the Optionee.  The terms of
the  Plan  and this  Option  Agreement  shall  be  binding  upon the  executors,
administrators, heirs, successors and assigns of the Optionee.

         5. Term of Option.  This Option may be  exercised  only within the Term
set out in the Notice of Grant.


                                       2


         6. Early Termination of Option.

            (a)  Termination  of  Status  as  Employee,  Consultant  or  Outside
Director. If Optionee's Continuous Status as an Employee,  Consultant or Outside
Director  terminates,  (but not in the event of a change of status from Employee
to Consultant or Outside  Director (in which case an Employee's  Incentive Stock
Option  shall  automatically  convert  to a  Nonstatutory  Stock  Option  on the
ninety-first  (91st) day following such change of status) or from  Consultant or
Outside Director to Employee), then this Option will terminate 30 days after the
date of termination  to the extent  Optionee has not exercised the Option before
that time, but in no event later than the Expiration Date.

            (b) Termination Due to Disability.  If Optionee's  Continuous Status
as an Employee or Consultant  terminates as a result of Optionee's permanent and
total  disability (as defined in Internal Revenue Code Section  22(e)(3)),  then
Optionee may exercise the Option,  up to the extent otherwise so entitled at the
date of termination of Continuous  Status, for up to 12 months after the date of
termination  of  Continuous  Status,  but in no event later than the  Expiration
Date, to the extent Optionee has not exercised the Option before that time.

            (c) Termination Upon Death.

                (i) If Optionee dies while in  Continuous  Status as an Employee
or  Consultant,  the  Option  may be  exercised  at any time  within  12  months
following the date of death (but in no event later than the Expiration Date), by
Optionee's  estate or by a person who  acquired the right to exercise the Option
by bequest or  inheritance,  but only to the extent the Optionee  could exercise
the Option at the date of death.

                (ii) If Optionee dies within 30 days after Optionee's Continuous
Status as an Employee or Consultant terminates, then this Option shall terminate
6 months after the date of death to the extent it has not been exercised  before
that  time by  Optionee's  estate,  or by a person  who  acquired  the  right to
exercise this Option by bequest or  inheritance.  In this case, the Option shall
be  exercisable  only to the extent of the right to exercise that had accrued at
the date of termination of Continuous Status as an Employee or Consultant.

            (d) No  Extension  of Term.  In no event  shall  the  exercisability
provisions of this Section 6 be interpreted to extend the Term of the option set
forth in the Notice of Grant.

         7. Tax  Consultation.  Purchaser  understands that Purchaser may suffer
adverse tax  consequences as a result of Purchaser's  purchase or disposition of
the Shares.  Purchaser  represents  that  Purchaser has  consulted  with any tax
consultants  Purchaser  deems  advisable  in  connection  with the  purchase  or
disposition  of the Shares and that  Purchaser is not relying on the Company for
any tax advice.

         8. Tax  Consequences. Some of the US federal and state tax consequences
relating  to  exercise  of this  Option  are set forth  below.  THIS  SUMMARY IS
NECESSARILY INCOMPLETE AND DOES NOT APPLY TO NON-US TAXPAYERS.  THE TAX LAWS AND
REGULATIONS ARE SUBJECT TO CHANGE.

                (i) Incentive Stock Option ("ISO").  If the Option  qualifies as
an ISO,  Purchaser  will have no regular  federal income tax or state income tax
liability  upon its  exercise,  although the excess,  if any, of the fair market
value of the  Exercised  Shares on the date of  exercise  over  their  aggregate
Exercise Price will be treated as an adjustment to the  alternative  minimum tax
for federal tax purposes and may subject Purchaser to alternative minimum tax in
the year of exercise.

                (ii) Nonqualified  Stock Option ("NSO").  If the Option does not
qualify as an ISO,  Purchaser  may incur  regular  federal  income tax and state
income tax liability upon exercise. Purchaser will be treated as having received
compensation  income (taxable at ordinary income tax rates) equal to the excess,
if any, of the fair market value of the Exercised Shares on the date of exercise
over their aggregate  Exercise  Price. If Purchaser is an employee,  the Company
will be  required  to  withhold  from his or her  compensation  or collect  from
Optionee  and pay to the  applicable  taxing  authorities  an amount  equal to a
percentage of this compensation income at the time of exercise.

         9.  Optionee's  Representations.  Optionee  understands  this Option is
granted  under and  governed  by the terms and  conditions  of the Plan and this
Option  Agreement,  which are governed by Delaware  law,  constitute  the entire
agreement of the parties and supersede  all prior  agreements of the Company and
Optionee with respect to the subject  matter  hereof.  Optionee has reviewed the
Plan and this Option  Agreement in their  entirety,  has had an  opportunity  to
obtain the advice of counsel prior to executing this Option  Agreement and fully
understands  all provisions of the Plan and Option  Agreement.  Optionee  hereby
agrees  to  accept  as  binding,   conclusive   and  final  all   decisions   or
interpretations of the Administrator upon any questions relating to the Plan and
Option Agreement.
