--------------------------------------------------------------------------------

4. Shares Available.

Subject to the provisions of Section 7, Three Thousand (3,000) Shares may be
issued pursuant to Options granted under the Plan. In the event that an Option
expires or terminates for any reason without having been exercised in full, the
Shares subject to but not issued under such Option shall, unless the Plan shall
have been terminated, become available for other Options.

5. Granting of Options.

(a) Eligibility. The Committee may, from time to time, grant Options to one or
more Employees. An Employee who has been granted an Option may, if he or she is
otherwise eligible, be granted an additional Option or Options before exercising
a prior Option. The Committee shall grant Options only within ten (10) years
from the date the Plan is adopted or the date the Plan is approved by the
shareholders of the Corporation, whichever is earlier.

(b) Option Agreement. Each Option shall be evidenced by an Option Agreement
which shall be signed by a member of the Committee and the Optionee. Each Option
Agreement shall incorporate the terms and restrictions of the Plan and such
additional terms and restrictions not inconsistent therewith as determined by
the Committee and shall indicate that the Option will not be treated as an
incentive stock option under Section 422 of the Code. Upon acceptance of an
Option Agreement, the Optionee shall be bound by the terms and restrictions of
the Plan and of the Option Agreement.

(c) Term of Option. Unless sooner terminated, each Option shall expire not later
than ten (10) years from the date such Option is granted.

(d) Option Price. The option price for Shares to be issued under any Option
shall not be less than one hundred percent (100%) of the fair market value of
such Shares on the date the Option is granted.

(e) Non-Transferability of Options. Options may not be sold, pledged, assigned,
hypothecated, transferred or disposed of in any manner other than by will or by
the laws of descent and distribution, and may be exercised during the lifetime
of the Optionee only by such Optionee.

6. Exercise of Options.

(a) Manner of Exercise. Options granted under the Plan shall be exercisable at
such times under such circumstances as shall be permissible under the terms of
the Plan and the Option Agreements. An Option shall be deemed to be exercised
when written notice of such exercise has been given by the Optionee to the
Corporation in accordance with terms of the Option Agreement and full payment
for the Shares with respect to which the Option is exercised has been received
by the Corporation. Payment shall be made by certified check, transfer of
Shares, or a combination thereof.

(b) Involuntary Termination of Employment for Other than Good Cause. In the
event an Optionee ceases to be employed by the Corporation, a Parent, or any
Subsidiary, and is no longer employed by any of them, for any reason other than
voluntary termination, involuntary termination for good cause, death or
disability, all outstanding Options granted to such Optionee shall automatically
expire three (3) months after the date the Optionee’s employment ceases or on
the expiration date provided in the applicable Option Agreement, whichever is
earlier.

(c) Voluntary Termination of Employment. In the event an Optionee voluntarily
terminates employment with the Corporation, a Parent, or any Subsidiary and is
no longer employed by any of them, all outstanding Options granted to such
Optionee shall automatically expire on the date his or her employment
terminates.

(d) Involuntary Termination of Employment for Good Cause. In the event an
Optionee’s employment with the Corporation, a Parent, or any Subsidiary is
terminated for good cause and he or she is no longer employed by any of them,
all outstanding Options granted to such Optionee shall automatically expire on
the date his or her employment terminates.

For purposes of this Plan, “good cause” shall mean:

(i) Conviction of the Optionee of a crime which is punishable as a felony; and

(ii) An Optionee’s willful breach of a material duty of his or her employment
and his or her failure to cure such breach within thirty (30) days after
receiving written notice thereof from the Board.

(e) Disabled Optionee. In the event an Optionee ceases to be employed by the
Corporation, a Parent, or any Subsidiary by reason of disability and is no
longer employed by any of them, all outstanding Options granted to such Optionee
shall automatically expire one (1) year after the date such Optionee’s
employment ceases or on the expiration date provided in the applicable Option
Agreement, whichever is earlier.

--------------------------------------------------------------------------------

For purposes of this Plan, “disability” means an Optionee’s inability to engage
in any substantial gainful activity by reason of any medically determinable
physical or mental impairment which can be expected to result in death or which
has lasted or can be expected to last for a continuous period of not less than
twelve (12) months. An Optionee shall furnish proof of disability in such form
and manner and at such times as the Committee may require.

(f) Death of Optionee. In the event an Optionee dies while in the employ of the
Corporation, a Parent, or any Subsidiary, then to the extent the Optionee would
have been entitled to exercise an Option immediately prior to his or her death,
such Option may be exercised by the estate of such Optionee or by such person or
persons to whom such Optionee’s rights pass by will or by the laws of descent
and distribution at any time prior to the expiration date provided in the
applicable Option agreement or within one (1) year after the death of the
Optionee, whichever is earlier.

7. Adjustments.

If there is any change in the Common Stock of the corporation through the
declaration of stock dividends, through recapitalization resulting in stock
splits, or combinations or exchanges of shares or otherwise, the Committee shall
make appropriate adjustments to the number of Shares available for Option and
the Option Price and number of Shares subject to Options.

8. Amendment and Termination.

(a) Amendment. The Board, without further approval of the shareholders of the
Corporation, may amend the Plan from time to time in such respects as the Board
may deem advisable, provided that no amendment shall become effective prior to
approval by the shareholders of the Corporation which:

(i) increases the maximum number of shares for which Options may be granted; or

(ii) modifies the class of Employees eligible to participate in the Plan.

(b) Termination. The Board, without further approval of the shareholders of the
Corporation, may at any time terminate the Plan.

(c) Effect of Amendment or Termination. Any such amendment or termination of the
Plan shall not affect Options already granted and such Options shall remain in
full force and effect as if the Plan had not been amended or terminated.

9. Effective Date of Plan.

The Plan shall be effective upon its adoption by the Board or its approval by
the shareholders of the Corporation, whichever is later.

10. Miscellaneous.

(a) Employment. The granting of an Option to an Employee shall not give the
Employee any right to be retained in the employ of the Corporation or any
Subsidiary.

(b) Headings. Paragraph headings are included solely for convenience and shall
in no event affect, or be used in connection with, the interpretation of the
Plan.
