         2.    MANNER OF EXERCISE.

               (a)  The Optionee may exercise this Stock Option only in the
following manner: from time to time on or prior to the Expiration Date of this
Stock Option, the Optionee may give written notice to the Administrator of his
or her election to purchase some or all of the Option Shares purchasable at the
time of such notice. This notice shall specify the number of Option Shares to be
purchased.

         Payment of the purchase price for the Option Shares may be made by one
or more of the following methods: (i) in cash, by certified or bank check or
other instrument acceptable to the Administrator; (ii) through the delivery (or
attestation to the ownership) of shares of Stock that have been purchased by the
Optionee on the open market or that are beneficially owned by the Optionee and
are not then subject to any restrictions under any Company plan and that
otherwise satisfy any holding periods as may be required by the Administrator;
(iii) by the Optionee delivering to the Company a properly executed exercise
notice together with irrevocable instructions to a broker to promptly deliver to
the Company cash or a check payable and acceptable to the Company to pay the
option purchase price, provided that in the event the Optionee chooses to pay
the option purchase price as so provided, the Optionee and the broker shall
comply with such procedures and enter into such agreements of indemnity and
other agreements as the Administrator shall prescribe as a condition of such
payment procedure; or (iv) a combination of (i), (ii) and (iii) above. Payment
instruments will be received subject to collection.

         The transfer to the Optionee on the records of the Company or of the
transfer agent of the Option Shares will be contingent upon the Company's
receipt from the Optionee of full payment for the Option Shares, as set forth
above and any agreement, statement or other evidence that the Company may
require to satisfy itself that the issuance of Stock to be purchased pursuant to
the exercise of Stock Options under the Plan and any subsequent resale of the
shares of Stock will be in compliance with applicable laws and regulations. In
the event the Optionee chooses to pay the purchase price by previously-owned
shares of Stock through the attestation method, the number of shares of Stock
transferred to the Optionee upon the exercise of the Stock Option shall be net
of the shares attested to.

               (b)  The shares of Stock purchased upon exercise of this Stock
Option shall be transferred to the Optionee on the records of the Company or of
the transfer agent upon compliance to the satisfaction of the Administrator with
all requirements under applicable laws or regulations in connection with such
issuance and with the requirements hereof and of the Plan. The determination of
the Administrator as to such compliance shall be final and binding on the
Optionee. The Optionee shall not be deemed to be the holder of, or to have any
of the rights of a holder with respect to, any shares of Stock subject to this
Stock Option unless and until this Stock Option shall have been exercised
pursuant to the terms hereof, the Company or the transfer agent shall have
transferred the shares to the Optionee, and the Optionee's name shall have been
entered as the stockholder of record on the books of the Company. Thereupon, the
Optionee shall have full voting, dividend and other ownership rights with
respect to such shares of Stock.

               (c)  The minimum number of shares with respect to which this
Stock Option may be exercised at any one time shall be 100 shares, unless the
number of shares with respect to

                                        2
<Page>

which this Stock Option is being exercised is the total number of shares subject
to exercise under this Stock Option at the time.

               (d)  Notwithstanding any other provision hereof or of the Plan,
no portion of this Stock Option shall be exercisable after the Expiration Date
hereof.

         3.    TERMINATION OF EMPLOYMENT.  If the Optionee's employment by the
Company or a Subsidiary (as defined in the Plan) is terminated, the period
within which to exercise the Stock Option may be subject to earlier termination
as set forth below.

               (a)  TERMINATION DUE TO DEATH. If the Optionee's employment
terminates by reason of the Optionee's death, any portion of this Stock Option
outstanding on such date shall become fully exercisable and may thereafter be
exercised by the Optionee's legal representative or legatee for a period of 12
months from the date of death or until the Expiration Date, if earlier.

               (b)  TERMINATION DUE TO DISABILITY. If the Optionee's employment
terminates by reason of the Optionee's disability (as determined by the
Administrator), any portion of this Stock Option outstanding on such date shall
become fully exercisable and may thereafter be exercised by the Optionee for a
period of 12 months from the date of termination or until the Expiration Date,
if earlier. The death of the Optionee during the 12-month period provided in
this Section 3(b) shall extend such period for another 12 months from the date
of death or until the Expiration Date, if earlier.

               (c)  TERMINATION FOR CAUSE. If the Optionee's employment
terminates for Cause, any portion of this Stock Option outstanding on such date
shall terminate immediately and be of no further force and effect. For purposes
hereof, "Cause" shall mean, unless otherwise provided in an employment agreement
between the Company and the Optionee, a vote by the Board resolving that the
Optionee shall be dismissed as a result of (i) any material breach by the
Optionee of any agreement between the Optionee and the Company; (ii) the
conviction of, indictment for or plea of nolo contendere by the Optionee to a
felony or a crime involving moral turpitude; or (iii) any material misconduct or
willful and deliberate non-performance (other than by reason of disability) by
the Optionee of the Optionee's duties to the Company.

               (d)  OTHER TERMINATION. If the Optionee's employment terminates
for any reason other than the Optionee's death, the Optionee's disability, or
Cause, and unless otherwise determined by the Administrator, any portion of this
Stock Option outstanding on such date may be exercised, to the extent
exercisable on the date of termination, for a period of three months from the
date of termination or until the Expiration Date, if earlier. Any portion of
this Stock Option that is not exercisable on the date of termination shall
terminate immediately and be of no further force or effect.

         The Administrator's determination of the reason for termination of the
Optionee's employment shall be conclusive and binding on the Optionee and his or
her representatives or legatees.

         4.    INCORPORATION OF PLAN. Notwithstanding anything herein to the
contrary, this Stock Option shall be subject to and governed by all the terms
and conditions of the Plan, including the powers of the Administrator set forth
in Section 2(b) of the Plan. Capitalized terms

                                        3
<Page>

in this Agreement shall have the meaning specified in the Plan, unless a
different meaning is specified herein.

         5.    TRANSFERABILITY.  This Agreement is personal to the Optionee, is
non-assignable and is not transferable in any manner, by operation of law or
otherwise, other than by will or the laws of descent and distribution. This
Stock Option is exercisable, during the Optionee's lifetime, only by the
Optionee, and thereafter, only by the Optionee's legal representative or
legatee.

         6.    STATUS OF THE STOCK OPTION. This Stock Option is intended to
qualify as an "incentive stock option" under Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"), but the Company does not represent or
warrant that this Stock Option qualifies as such. The Optionee should consult
with his or her own tax advisors regarding the tax effects of this Stock Option
and the requirements necessary to obtain favorable income tax treatment under
Section 422 of the Code, including, but not limited to, holding period
requirements. To the extent any portion of this Stock Option does not so qualify
as an "incentive stock option," such portion shall be deemed to be a
non-qualified stock option. If the Optionee intends to dispose or does dispose
(whether by sale, gift, transfer or otherwise) of any Option Shares within the
one-year period beginning on the date after the transfer of such shares to him
or her, or within the two-year period beginning on the day after the grant of
this Stock Option, he or she will so notify the Company within 30 days after
such disposition.

         7.    TAX WITHHOLDING. The Optionee shall, not later than the date as
of which the exercise of this Stock Option becomes a taxable event for Federal
income tax purposes, pay to the Company or make arrangements satisfactory to the
Administrator for payment of any Federal, state, and local taxes required by law
to be withheld on account of such taxable event. The Optionee may elect to have
the minimum required tax withholding obligation satisfied, in whole or in part,
by (i) authorizing the Company to withhold from shares of Stock to be issued, or
(ii) transferring to the Company, a number of shares of Stock with an aggregate
Fair Market Value that would satisfy the withholding amount due.

         8.    NO OBLIGATION TO CONTINUE EMPLOYMENT. Neither the Company nor any
Subsidiary is obligated by or as a result of the Plan or this Agreement to
continue the Optionee in employment and neither the Plan nor this Agreement
shall interfere in any way with the right of the Company or any Subsidiary to
terminate the employment of the Optionee at any time.

         9.    NOTICES. Notices hereunder shall be mailed or delivered to the
Company at its principal place of business and shall be mailed or delivered to
the Optionee at the address on file with the Company or, in either case, at such
other address as one party may subsequently furnish to the other party in

some or all of the Option Shares purchasable at the time of such notice. This
notice shall specify the number of Option Shares to be purchased.

         Payment of the purchase price for the Option Shares may be made by one
or more of the following methods: (i) in cash, by certified or bank check or
other instrument acceptable to the Administrator; (ii) through the delivery (or
attestation to the ownership) of shares of Stock that have been purchased by the

are not then subject to any restrictions under any Company plan and that
otherwise satisfy any holding periods as may be required by the Administrator;
(iii) by the Optionee delivering to the Company a properly executed exercise
notice together with irrevocable instructions to a broker to promptly deliver to
the Company cash or a check payable and acceptable to the Company to pay the
option purchase price, provided that in the event the Optionee chooses to pay
the option purchase price as so provided, the Optionee and the broker shall
comply with such procedures and enter into such agreements of indemnity and
other agreements as the Administrator shall prescribe as a condition of such
payment procedure; or (iv) a combination of (i), (ii) and (iii) above. Payment
instruments will be received subject to collection.

         The transfer to the Optionee on the records of the Company or of the
transfer agent of the Option Shares will be contingent upon the Company's
receipt from the Optionee of full payment for the Option Shares, as set forth
above and any agreement, statement or other evidence that the Company may

the exercise of Stock Options under the Plan and any subsequent resale of the
shares of Stock will be in compliance with applicable laws and regulations. In
the event the Optionee chooses to pay the purchase price by previously-owned
shares of Stock through the attestation method, the number of shares of Stock
transferred to the Optionee upon the exercise of the Stock Option shall be net
of the Shares attested to.

               (b)  The shares of Stock purchased upon exercise of this Stock
Option shall be transferred to the Optionee on the records of the Company or of
the transfer agent upon compliance to the satisfaction of the Administrator with
all requirements under applicable laws or regulations in connection with such
issuance and with the requirements hereof and of the Plan. The determination of
the Administrator as to such compliance shall be final and binding on the
Optionee. The Optionee shall not be deemed to be the holder of, or to have any
of the rights of a holder with respect to, any shares of Stock subject to this
Stock Option unless and until this Stock Option shall have been exercised
pursuant to the terms hereof, the Company or the transfer agent shall have
transferred the shares to the Optionee, and the Optionee's name shall have been
entered as the stockholder of record on the books of the Company. Thereupon, the
Optionee shall have full voting, dividend and other ownership rights with
respect to such shares of Stock.

               (c)  The minimum number of shares with respect to which this
Stock Option may be exercised at any one time shall be 100 shares, unless the
number of shares with respect to which this Stock Option is being exercised is
the total number of shares subject to exercise under this Stock Option at the
time.

hereof.

         3.    TERMINATION OF EMPLOYMENT.  If the Optionee's employment by the
Company or a Subsidiary (as defined in the Plan) is terminated, the period
within which to exercise the Stock Option may be subject to earlier termination
as set forth below.

               (a)  TERMINATION DUE TO DEATH. If the Optionee's employment
terminates by reason of the Optionee's death, any portion of this Stock Option
outstanding on such date shall become fully exercisable and may thereafter be
exercised by the Optionee's legal representative or legatee for a period of 12
months from the date of death or until the Expiration Date, if earlier.

               (b)  TERMINATION DUE TO DISABILITY. If the Optionee's employment
terminates by reason of the Optionee's disability (as determined by the
Administrator), any portion of this Stock Option outstanding on such date shall
become fully exercisable and may thereafter be exercised by the Optionee for a
period of 12 months from the date of termination or until the Expiration Date,
if earlier. The death of the Optionee during the 12-month period provided in
this Section 3(b) shall extend such period for another 12 months from the date
of death or until the Expiration Date, if earlier.

               (c)  TERMINATION FOR CAUSE. If the Optionee's employment
terminates for Cause, any portion of this Stock Option outstanding on such date
shall terminate immediately and be of no further force and effect. For purposes
hereof, "Cause" shall mean, unless otherwise provided in an employment agreement
between the Company and the Optionee, a vote by the Board resolving that the
Optionee shall be dismissed as a result of (i) any material breach by the
Optionee of any agreement between the Optionee and the Company; (ii) the
conviction of, indictment for or plea of nolo contendere by the Optionee to a
felony or a crime involving moral turpitude; or (iii) any material misconduct or
willful and deliberate non-performance (other than by reason of disability) by
the Optionee of the Optionee's duties to the Company.

               (d)  OTHER TERMINATION. If the Optionee's employment terminates
for any reason other than the Optionee's death, the Optionee's disability or
Cause, and unless otherwise determined by the Administrator, any portion of this
Stock Option outstanding on such date may be exercised, to the extent
exercisable on the date of termination, for a period of three months from the
date of termination or until the Expiration Date, if earlier. Any portion of
this Stock Option that is not exercisable on the date of termination shall
terminate immediately and be of no further force or effect.

         The Administrator's determination of the reason for termination of the
Optionee's employment shall be conclusive and binding on the Optionee and his or
her representatives or legatees.

         4.    INCORPORATION OF PLAN. Notwithstanding anything herein to the
contrary, this Stock Option shall be subject to and governed by all the terms
and conditions of the Plan, including the powers of the Administrator set forth
in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the
meaning specified in the Plan, unless a different meaning is specified herein.

         5.    TRANSFERABILITY. This Agreement is personal to the Optionee, is
non-assignable and is not transferable in any manner, by operation of law or
otherwise, other than by will or the laws of descent and distribution. This
Stock Option is exercisable, during the Optionee's lifetime, only by the
Optionee, and thereafter, only by the Optionee's legal representative or
legatee.

         6.    TAX WITHHOLDING. The Optionee shall, not later than the date as
of which the exercise of this Stock Option becomes a taxable event for Federal
income tax purposes, pay to the Company or make arrangements satisfactory to the
Administrator for payment of any Federal, state, and local taxes required by law
to be withheld on account of such taxable event. The Optionee may elect to have
the minimum required tax withholding obligation satisfied, in whole or in part,
by (i) authorizing the Company to withhold from shares of Stock to be issued, or
(ii) transferring to the Company, a number of shares of Stock with an aggregate
Fair Market Value that would satisfy the withholding amount due.

         7.    NO OBLIGATION TO CONTINUE EMPLOYMENT. Neither the Company nor any
Subsidiary is obligated by or as a result of the Plan or this Agreement to
continue the Optionee in employment and neither the Plan nor this Agreement
shall interfere in any way with the right of the Company or any Subsidiary to
terminate the employment of the Optionee at any time.
