portion of such Option may, prior to the time when such portion becomes
unexercisable under the provisions of Paragraph 8, above, be exercised by the
Outside Director's personal representative or by any person empowered to do so
under court order, or by will or the laws of descent and distribution, unless
otherwise determined by the Board of Directors.

(b)    Manner of Exercise. An Option, or any exercisable portion thereof, may be
exercised solely by delivery to the Company of all of the following prior to the
time when such Option or portion thereof becomes unexercisable under Paragraph
8:
 
(i)    Notice in writing signed by the Outside Director or other person then
entitled to exercise such Option or portion, stating that such Option or portion
is exercised;

(ii)    Either:
 
     (x)    Full payment (in cash or by check) for the shares with respect to
which such Option or portion is thereby exercised; or
 
     (y)    Upon conditions established by the Board of Directors, by the
delivery or constructive exchange of shares of Common Stock owned by the Outside
Director for such period of time as may be established by the Board of
Directors, such shares having a Fair Market Value equal to the aggregate

     (z)    Any combination of the consideration provided in the foregoing
subsections (x) and (y);
 
(iii)    In the event the Option or a portion thereof is being exercised by any

granted, appropriate proof, reasonably satisfactory to the Company, of the
authority of such person or persons to exercise the Option or such portion
thereof; and
 
(iv)    The Board of Directors may make such provisions, subject to applicable
rules and regulations, as it may deem appropriate for the withholding or payment
by the Outside Director of any withholding taxes that it determines are required
in connection with the exercise of an Option, and an Outside Director's rights
in stock issued pursuant to such exercise are subject to satisfaction of such
conditions. If permitted by the Board of Directors, an Outside Director may
elect to satisfy all or any portion of such taxes by instructing the Company to
withhold shares of Common Stock issued pursuant to the exercise of the Option.
If shares of Common Stock are withheld to satisfy tax liabilities, the value of

5

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

Exhibit 10.21

such shares shall be computed using the Fair Market Value of the Common Stock on
the Tax Date.

Any election to use Common Stock to satisfy a withholding tax obligation must
either (A) be in a written instrument signed by the Outside Director and stating
the number of shares to be withheld or surrendered or a formula pursuant to
which such number may be determined and be irrevocable; or (B) otherwise be made
in compliance with the Rules and Regulations of the Securities and Exchange
Commission under the 1934 Act relating to such elections, as from time to time
in effect.

In no event shall the Company be required to issue fractional shares.

(c)    Rights as a Shareholder. A holder of an Option shall not be, and shall
not have any of the rights or privileges of, a shareholder of the Company with
respect to any shares of Common Stock purchasable upon the exercise of such
Option unless and until such Option shall have been exercised and a certificate
or certificates evidencing such shares shall have been issued by the Company to
such holder.

(d)    Conditions to Issuance of Stock Certificates. The Company shall not be
required to issue or deliver any certificate or certificates for shares of stock
purchased upon the exercise of any Option or portion thereof unless and until
all legal requirements applicable to such issuance or delivery have, in the
opinion of counsel to the Company, been complied with. In connection with any
such issuance or transfer, the person acquiring the shares shall, if requested
by the Company, give assurances satisfactory to such counsel in respect of such
matters as such counsel may deem desirable to assure compliance with all
applicable legal requirements.
 
10.    Restrictions on Transferability.

(a)    No Option or interest or right therein or part thereof shall be subject
to or liable for the debts, contracts or engagements of the Outside Director or
the Outside Director's successors in interest, as the case may be, or shall be
subject to disposition by transfer, alienation, anticipation, pledge,
encumbrance, assignment or any other means whether such disposition be voluntary
or involuntary or by operation of law by judgment, levy, attachment, garnishment
or any other legal or equitable proceedings (including bankruptcy), and any
attempted disposition thereof shall be null and void and of no effect; provided,
however, that nothing in this Paragraph 10 shall prevent transfers permitted by
Paragraph 9(a) or Paragraph 10(b).

(b)    Except as otherwise provided by the Board of Directors:
 
(i)    Options granted or awarded pursuant to the Plan shall not be transferable
other than by will or by the laws of descent and distribution and the rights of
Director under this Plan shall not be assignable or transferable pursuant to a
qualified domestic relations order as defined in the Internal Revenue Code of
1986, as amended, Title I of the Employee Retirement Income Security Act or the
rules thereunder; and

(ii)    During the lifetime of an Outside Director, an Option shall be
exercisable only by the Outside Director personally, or by the Outside
Director's legal representative.
 
11.    Stock Awards.

(a)    In the discretion of the Board of Directors, the Company may make Stock
Awards to Outside Directors. Stock Awards may be in the form of Common Stock,
Restricted Stock Units, or Restricted Stock or any combination thereof. No Stock
Award to an Outside Director may exceed 5,000 shares of Common Stock in any
year. Unless otherwise determined by the Board of Directors, Stock Awards may
not be made to an individual who has at any time been employed by the Company.

(b)    Stock Awards to Outside Directors for the first year that they serve as
directors shall be in

6

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

Exhibit 10.21

the form of Restricted Stock or Restricted Stock Units. Restricted Stock awarded
under this Plan may not be sold, exchanged, transferred, pledged, hypothecated
or otherwise disposed of, and in the event of the Outside Director's ceasing to
serve as a director of the Company for any reason (including death and
Disability unless the Board of Directors in its sole discretion terminates the
Forfeiture Restrictions following the death or Disability of such Outside
Director), the Outside Director shall be obligated, for no consideration, to
forfeit and surrender such shares (to the extent then subject to the Forfeiture
Restrictions) to the Company. The restrictions against disposition and the
obligation to forfeit and surrender shares to the Company are herein referred to
as “Forfeiture Restrictions”, and the shares that are then subject to the
Forfeiture Restrictions are referred to as “Restricted Stock.” Certificates
evidencing Restricted Stock shall be appropriately legended to reflect the
Forfeiture Restrictions. Restricted Stock Units are Stock Awards denominated in
units of Common Stock under which the issuance of Common Stock is subject to
such vesting conditions (including continued service as an Outside Director) and
other terms and conditions as the Board of Directors deems appropriate. Each
Restricted Stock Unit will be equal to one share of Common Stock and will,
subject to satisfaction of any vesting and/or other terms and conditions,
entitle an Outside Director to the issuance of one share of Common Stock in
settlement of the award.

(c)    The Forfeiture Restrictions with respect to Restricted Stock awarded to
an Outside Director shall lapse and be of no further force and effect, and
Restricted Stock Units awarded to an Outside Director shall vest, in each case
upon the expiration of such period of time as may be fixed by the Board of
Directors prior to the issuance of such Stock Award. In no event shall the
restriction period be less than six months from the date the Stock Award is
granted.

(d)    All of the foregoing restrictions, terms and other conditions regarding
shares of Restricted Stock or Restricted Stock Units shall be evidenced by a
written agreement between the Company and the Outside Director containing such
terms and conditions, not inconsistent with the Plan, as the Board of Directors
shall approve.

(e)    The Board of Directors may make such provisions as it may deem
appropriate, subject to applicable rules and regulations, for the withholding or
payment by the Outside Director of any withholding taxes that it determines are
required in connection with Stock Awards and the lapse of Forfeiture
Restrictions on Restricted Stock, and an Outside Director's rights in such stock
are subject to satisfaction of such conditions. If permitted by the Board of
Directors, an Outside Director may elect to satisfy all or any portion of such
taxes by instructing the Company to withhold shares of Common Stock from a Stock
Award or from Restricted Stock as to which the Restrictions have lapsed.

(f)    If shares of Common Stock are withheld to satisfy tax liabilities, the
value of such shares shall be computed using the Fair Market Value of the Common
Stock on the Tax Date.

(g)    An Outside Director may not defer the receipt of Common Stock with
respect to a Restricted Stock Unit beyond the date set forth in the Agreement
between the Company and the Outside Director.

12.    Effective Date of the Plan.

This Plan is conditional upon the approval of the shareholders of the Company,
and the Plan shall be null and void if it is not approved by the shareholders
within twelve months of its approval by the Board of Directors.

13.    Amendment, Suspension and Termination of Plan.

Except as provided in this Paragraph 13 and in Paragraph 15, the Board of
Directors may amend or terminate the Plan at any time and in any respect.

7

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

Exhibit 10.21

(a)    No amendment of the Plan shall become effective without the approval of
the Company's shareholders if such approval is required in order to comply with
Rule 16b-3 under the Exchange Act or any other applicable law, rule or
regulation.

(b)    Unless required by applicable law, rule or regulation, no amendment or
termination of the Plan shall affect in a material and adverse manner any Option
granted prior to the date of such amendment or termination without the written
consent of the Outside Director holding such affected Option.

(c)    This Plan is intended to comply with all requirements for the exemption
from Section 16(b) of the 1934 Act applicable to Outside Directors provided by
Rule 16-3 or its successors under the 1934 Act. To the extent any provision of
the Plan does not so comply and cannot for any reason be amended by the Board of
Directors or the shareholders of the Company so as to comply, the provision
shall, to the extent permitted by law and deemed advisable by the Board of
Directors, be deemed null and void with respect to the holder of Options granted
under this Plan.

(d)    Following the commencement of an averaging period used to determine the
Grant Price of an Option, the Board of Directors may not (i) decline to issue
the Option, or (ii) amend either the number or class of shares of stock that are
subject to the Option, the method for determining the Grant Price, or the length
of the averaging period.

14.    Governing Law.

This Plan shall be governed by and construed and enforced in accordance with,
the laws of the State of Delaware without giving effect to its choice of law
rules.
 
15.    Code Section 409A

It is intended that the Options and Restricted Stock Awards issued pursuant to
this Plan shall not constitute “deferrals of compensation” within the meaning of
Section 409A of the Internal Revenue Code and, as a result, shall not be subject
to the requirements of Section 409A. It is further intended that Restricted
Stock Units issued pursuant to this Plan shall avoid any “plan failures” within
the meaning of Code section 409A(a)(1). The Plan is to be interpreted in a
manner consistent with these intentions.

Notwithstanding any other provision in this Plan, a new Option or Restricted
Stock Award may not be issued if such Option or Restricted Stock Award would be
subject to Section 409A, and an existing Option or Restricted Stock Award may
not be modified in a manner that would cause such Option or Restricted Stock
Award to become subject to Section 409A.

16.    Termination of the Plan.

Unless previously terminated by the Board of Directors, the Plan shall terminate
when there are no longer any Options, Restricted Stock Units, or shares of
Restricted Stock outstanding.
