requirements of any stock exchange or quotation service upon which the Shares

Shares shall be considered transferred to the Optionee on the date the Option is
exercised with respect to such Exercised Shares.

as Exhibit C, in the amount of the aggregate Exercise Price of the Exercised
Shares together with the execution and delivery by the Optionee of the Security

no less than the "applicable federal rate" prescribed under the Code and its
regulations at time of purchase, and shall be secured by a pledge of the Shares

connection with the Optionee's estate plan, be assigned in whole or in part
during Optionee's lifetime to one or more Family Members of the Optionee or to a
trust established for the exclusive benefit of one or more such Family Members.

grandparents, spouse, former spouse, siblings, nieces, nephews, mother-in-law,
father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law,
including adoptive relationships, a trust in which any of the

<PAGE>

foregoing individuals have more than a fifty percent (50%) beneficial interest,
a foundation in which any of the foregoing individuals (or the Optionee) control
the management of assets, and any other entity in which any of the foregoing
individuals (or Optionee) own more than fifty percent (50%) of the voting
interests.

      5.    Term of Option. This Option may be exercised only within the term
set out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.

      6.    Tax Consequences. Some of the federal and Delaware tax consequences
relating to this Option, as of the date of this Option, are set forth below.
THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE
SUBJECT TO CHANGE. THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING
THIS OPTION OR DISPOSING OF THE SHARES.

            (a)   Exercising the Option.

                  (i) Nonstatutory Stock Option. The Optionee may incur regular
federal tax liability upon exercise of a NSO. The Optionee 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 the Optionee is an
Employee or a former 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 in cash equal to a percentage of this compensation income
at the time of exercise, and may refuse to honor the exercise and refuse to
deliver Shares if such withholding amounts are not delivered at the time of
exercise.

                  (ii) Incentive Stock Option. If this Option qualifies as an
ISO, the Optionee will have no regular federal 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 alternative minimum taxable income for federal tax
purposes and may subject the Optionee to alternative minimum tax in the year of
exercise. In the event that the Optionee undergoes a change of status from
Employee to Consultant or Outside Director, any Incentive Stock Option of the
Optionee that remains unexercised three (3) months following such change in
status shall cease to qualify as an Incentive Stock Option and will be treated
for tax purposes as a Nonstatutory Stock Option.

            (b)   Disposition of Shares.

                  (i) NSO. If the Optionee holds NSO Shares for at least one
year, any gain realized on disposition of the Shares will be treated as
long-term capital gain for federal income tax purposes.

                                       4.
<PAGE>

                  (ii) ISO. If the Optionee holds ISO Shares for at least one
year after exercise and two years after the grant date, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes. If the Optionee disposes of ISO Shares within one year
after exercise or two years after the grant date, any gain realized on such
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the excess, if any, of the lesser of (A) the difference
between the Fair Market Value of the Shares acquired on the date of exercise and
the aggregate Exercise Price, or (B) the difference between the sale price of
such Shares and the aggregate Exercise Price.

            (c)   Notice of Disqualifying Disposition of ISO Shares. If the
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
an ISO on or before the later of (i) two years after the grant date, or (ii) one
year after the exercise date, the Optionee shall immediately notify the Company
in writing of such disposition. The Optionee agrees that he or she may be
subject to income tax withholding by the Company on the compensation income
recognized from such early disposition of ISO Shares by payment in cash or out
of the current earnings paid to the Optionee.

      7.    Entire Agreement; Governing Law. The Plan is incorporated herein by
reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee. This agreement is governed by Delaware law except for that body of law
pertaining to conflict of laws.

      By your signature and the signature of the Company's representative below,
you and the Company agree that this Option is granted under and governed by the
terms and conditions of the Plan and this Option Agreement. 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. Optionee further agrees to notify the Company upon any
change in the residence address indicated below.

Optionee's death, Disability or other termination of Optionee's Service, the
exercisability of the Option is governed by 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"),
which shall state the election to exercise the Option, the number of Shares in
respect of 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 provisions of the Plan. The Exercise Notice shall be signed by
the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company. 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 such fully executed
Exercise Notice accompanied by such aggregate Exercise Price.

                                       2.

      No Shares shall be issued pursuant to the exercise of this Option unless
such issuance and exercise complies with all relevant provisions of law 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 transferred to the Optionee on the date the Option is
exercised with respect to such Exercised Shares.

      3.    Method of Payment. Payment of the aggregate Exercise Price shall be
by any of the following, or a combination thereof, at the election of the
Optionee:

            (a) cash; or

            (b) check; or

            (c) delivery of a properly executed exercise notice together with
such other documentation as the Administrator and the broker, if applicable,
shall require to effect an exercise of the Option and delivery to the Company of
the sale or loan proceeds required to pay the exercise price; or

            (d) surrender of other Shares which (i) have been owned by the
Optionee for more than six (6) months on the date of surrender and (ii) have a
Fair Market Value on the date of surrender equal to the aggregate Exercise Price
of the Exercised Shares; or

            (e) to the extent expressly authorized by the Plan Administrator,
delivery of Optionee's promissory note (the "Note") in the form attached hereto
as Exhibit C, in the amount of the aggregate Exercise Price of the Exercised
Shares together with the execution and delivery by the Optionee of the Security
Agreement attached hereto as Exhibit B. The Note shall bear interest at a rate
no less than the "applicable federal rate" prescribed under the Code and its
regulations at time of purchase, and shall be secured by a pledge of the Shares
purchased by the Note pursuant to the Security Agreement.

      4.    Limited Transferability of Option. This Option shall be neither
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution following Optionee's death and may be exercised, during
Optionee's lifetime, only by Optionee. However, if this Option is designated a
Non-Statutory Option in Part I of this Agreement, then this Option may, in
connection with the Optionee's estate plan, be assigned in whole or in part
during Optionee's lifetime to one or more Family Members of the Optionee or to a
trust established for the exclusive benefit of one or more such Family Members.
The assigned portion shall be exercisable only by the person or persons who
acquire a proprietary interest in the Option pursuant to such assignment. The
terms applicable to the assigned portion shall be the same as those in effect
for this Option immediately prior to such assignment.

            For purposes of this Section 4, a Family Member shall be limited to
the Optionee's children, stepchildren, grandchildren, parents, stepparents,
grandparents, spouse, former spouse, siblings, nieces, nephews, mother-in-law,
father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law,
including adoptive relationships, a trust in which any of the

                                       3.
<PAGE>

foregoing individuals have more than a fifty percent (50%) beneficial interest,
a foundation in which any of the foregoing individuals (or the Optionee) control
the management of assets, and any other entity in which any of the foregoing
individuals (or Optionee) own more than fifty percent (50%) of the voting
interests.

      5.    Term of Option. This Option may be exercised only within the term
set out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.

      6.    Tax Consequences. Some of the federal and Delaware tax consequences
relating to this Option, as of the date of this Option, are set forth below.
THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE
SUBJECT TO CHANGE. THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING
THIS OPTION OR DISPOSING OF THE SHARES.

            (a)   Exercising the Option.

                  (i) Nonstatutory Stock Option. The Optionee may incur regular
federal tax liability upon exercise of a NSO. The Optionee 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 the Optionee is an
Employee or a former 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 in cash equal to a percentage of this compensation income
at the time of exercise, and may refuse to honor the exercise and refuse to
deliver Shares if such withholding amounts are not delivered at the time of
exercise.

                  (ii) Incentive Stock Option. If this Option qualifies as an
ISO, the Optionee will have no regular federal 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 alternative minimum taxable income for federal tax
purposes and may subject the Optionee to alternative minimum tax in the year of
exercise. In the event that the Optionee undergoes a change of status from
Employee to Consultant or Outside Director, any Incentive Stock Option of the
Optionee that remains unexercised three (3) months following such change in
status shall cease to qualify as an Incentive Stock Option and will be treated
for tax purposes as a Nonstatutory Stock Option.

            (b)   Disposition of Shares.

                  (i) NSO. If the Optionee holds NSO Shares for at least one
year, any gain realized on disposition of the Shares will be treated as
long-term capital gain for federal income tax purposes.

                                       4.
<PAGE>

                  (ii) ISO. If the Optionee holds ISO Shares for at least one
year after exercise and two years after the grant date, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes. If the Optionee disposes of ISO Shares within one year
after exercise or two years after the grant date, any gain realized on such
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the excess, if any, of the lesser of (A) the difference
between the Fair Market Value of the Shares acquired on the date of exercise and
the aggregate Exercise Price, or (B) the difference between the sale price of
such Shares and the aggregate Exercise Price.

            (c)   Notice of Disqualifying Disposition of ISO Shares. If the
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
an ISO on or before the later of (i) two years after the grant date, or (ii) one
year after the exercise date, the Optionee shall immediately notify the Company
in writing of such disposition. The Optionee agrees that he or she may be
subject to income tax withholding by the Company on the compensation income
recognized from such early disposition of ISO Shares by payment in cash or out
of the current earnings paid to the Optionee.

      7.    Entire Agreement; Governing Law. The Plan is incorporated herein by
reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with

Optionee. This agreement is governed by Delaware law except for that body of law
pertaining to conflict of laws.

      By your signature and the signature of the Company's representative below,

answers.
