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 govern.

         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 stock
administration 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  221 of Title 12 of the Code of  Federal  Regulations  ("Regulation  U") as
promulgated by the Federal Reserve Board. As a condition to the exercise of this
Option,  the Company may require  the  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  or  Consultant.  If  the
Optionee's Continuous Status as an Employee or Consultant terminates,  then this
Option will  terminate 30 days after the date of  termination  to the extent the
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 the Optionee's permanent
and total  disability  (as defined in Internal  Revenue Code Section  22(e)(3)),
then the  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. If the 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.

            (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.  Optionee  understands  that purchaser may suffer
adverse tax  consequences  as a result of Optionee's  purchase or disposition of
the Shares.  Optionee  represents  that  purchaser  has  consulted  with any tax
consultants  Optionee  deems  advisable  in  connection  with  the  purchase  or
disposition  of the Shares and that  Optionee  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 THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.

            Non-Statutory Stock Option ("NSO").  The purchaser may incur regular
federal income tax and state income tax liability  upon exercise.  The purchaser
will be treated as having received  compensation  income equal to the excess, if
any, of the fair market value or the sale price of the  Exercised  Shares on the
date of  exercise  over their  aggregate  Exercise  Price.  If  purchaser  is an
Employee,  the Company may be required to withhold from his or her  compensation
or collect from the 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.

            (a) 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.  The  Optionee  has  reviewed  the Plan and this Option
Agreement in their entirety,  and 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.
