AMENDMENT TO THE 

MERCANTILE
BANCORP, INC. PROFIT SHARING PLAN & TRUST 

EXHIBIT 10.9 

Amendment to
Profit Sharing Plan and Trust 

ARTICLE I

PREAMBLE

	
  1.1

  	
   
	
  Adoption and
  effective date of amendment. This amendment of the
  plan is adopted to reflect certain provisions of the Economic Growth and Tax
  Relief Reconciliation Act of 2001 (“EGTRRA”). This amendment is intended as
  good faith compliance with the requirements of EGTRRA and is to be construed
  in accordance with EGTRRA and guidance issued thereunder. Except as otherwise
  provided, this amendment shall be effective as of the first day of the first
  plan year beginning after December 31, 2001.

	
   
	
   
	
   

	
  1.2
	
   
	
  Supersession
  of inconsistent provisions. This amendment shall
  supersede the provisions of the plan to the extent those provisions are
  inconsistent with the provisions of this amendment.

ARTICLE II

ADOPTION AGREEMENT ELECTIONS

	
   
	
   
	
  

  
	
   
	
   
	
   

	
   
	
   
	
  The questions in this Article II only need to be completed in order
  to override the default provisions set forth below. If all of the default
  provisions will apply, then these questions should be skipped.

	
   
	
   
	
   

	
   
	
   
	
  Unless the employer elects otherwise in this Article II, the
  following defaults apply:

	
   
	
   
	
  1)
	
  The vesting schedule for matching contributions will be a 6 year graded
  schedule (if the plan currently has a graded schedule that does not satisfy
  EGTRRA) or a 3 year cliff schedule (if the plan currently has a cliff
  schedule that does not satisfy EGTRRA), and such schedule will apply to all
  matching contributions (even those made prior to 2002).

	
   
	
   
	
  2)
	
  Rollovers are automatically excluded in determining whether the
  $5,000 threshold has been exceeded for automatic cash-outs (if the plan is
  not subject to the qualified joint and survivor annuity rules and provides
  for automatic cash-outs). This is applied to all participants regardless of
  when the distributable event occurred.

	
   
	
   
	
  3)
	
  The suspension period after a hardship distribution is made will be 6
  months and this will only apply to hardship distributions made after 2001.

	
   
	
   
	
  4)
	
  Catch-up contributions will be allowed.

	
   
	
   
	
  5)
	
  For target benefit plans, the increased compensation limit of
  $200,000 will be applied retroactively (i.e., to years prior to 2002).

	
   
	
   
	
   
	
   

	
   
	
   
	
  

  
	
   
	
   
	
   
	
   

	
  2.1
	
   
	
  Vesting Schedule for Matching Contributions

	
   
	
   
	
   

	
   
	
   
	
  If there are
  matching contributions subject to a vesting schedule that does not satisfy
  EGTRRA, then unless otherwise elected below, for participants who complete an
  hour of service in a plan year beginning after December 31, 2001, the
  following vesting schedule will apply to all matching contributions subject
  to a vesting schedule:

	
   
	
   
	
   

	
   
	
   
	
  If the plan
  has a graded vesting schedule (i.e., the vesting schedule includes a vested
  percentage that is more than 0% and less than 100%) the following will apply:

	
  Years of vesting service

  	
   
	
   
	
  Nonforfeitable percentage

  100
	
  %
	
   

	
   
	
   
	
  If the plan
  does not have a graded vesting schedule, then matching contributions will be
  nonforfeitable upon the completion of 3 years of vesting service.

	
   
	
   
	
   

	
   
	
   
	
  In lieu of
  the above vesting schedule, the employer elects the following schedule:

	
   
	
   
	
  a.
	
  [   ]
	
  3 year cliff
  (a participant’s accrued benefit derived from employer matching contributions
  shall be nonforfeitable upon the participant’s completion of three years of
  vesting service).

	
   
	
   
	
  b.
	
  [   ]
	
  6 year
  graded schedule (20% after 2 years of vesting service and an additional 20%
  for each year thereafter).

  If the plan is not subject to the qualified joint and survivor annuity rules
  and includes involuntary cash-out provisions, then unless one of the options

  This Article shall apply to participants who complete an Hour of Service
  after December 31, 2001, with respect to accrued benefits derived from
  employer matching contributions made in plan years beginning after December
  31, 2001. Unless otherwise elected by the employer in Section 2.1 above, this
  Article shall also apply to all such participants with respect to accrued

INVOLUNTARY CASH-OUTS

	
  4.1
	
   
	
  Applicability
  and effective date. If the plan provides for
  involuntary cash-outs of amounts less than $5,000, then unless otherwise
  elected in Section 2.2 of this amendment, this Article shall apply for
  distributions made after December 31, 2001, and shall apply to all

  entire nonforfeitable account balance.

ARTICLE V

HARDSHIP DISTRIBUTIONS

	
  5.1
	
   
	
  Applicability
  and effective date. If the plan provides for
  hardship distributions upon satisfaction of the safe harbor (deemed)
  standards as set forth in Treas. Reg. Section 1.401(k)-1(d)(2)(iv), then this
  Article shall apply for calendar years beginning after 2001.

	
   
	
   
	
   

	
  5.2
	
   
	
  Suspension
  period following hardship distribution. A
  participant who receives a distribution of elective deferrals after December
  31, 2001, on account of hardship shall be prohibited from making elective
  deferrals and employee contributions under this and all other plans of the
  employer for 6 months after receipt of the distribution. Furthermore, if
  elected by the employer in Section 2.3 of this amendment, a participant who
  receives a distribution of elective deferrals in calendar year 2001 on
  account of hardship shall be prohibited from making elective deferrals and
  employee contributions under this and all other plans until the later of
  January 1, 2002, or 6 months after receipt of the distribution.

ARTICLE VI

CATCH-UP CONTRIBUTIONS

Catch-up
Contributions. Unless otherwise elected in Section 2.4
of this amendment, all employees who are eligible to make elective deferrals
under this plan and who have attained age 50 before the close of the plan year
shall be eligible to make catch-up contributions in accordance with, and
subject to the limitations of, Section 414(v) of the Code. Such catch-up
contributions shall not be taken into account for purposes of the provisions of
the plan implementing the required limitations of Sections 402(g) and 415 of
the Code. The plan shall not be treated as failing to satisfy the provisions of
the plan implementing the requirements of Section 401(k)(3), 401(k)(11),
401(k)(12), 410(b), or 416 of the Code, as applicable, by reason of the making
of such catch-up contributions.

ARTICLE VII

INCREASE IN COMPENSATION LIMIT

Increase in Compensation Limit. The annual
compensation of each participant taken into account in determining allocations
for any plan year beginning after December 31, 2001, shall not exceed $200,000,
as adjusted for cost-of-living increases in accordance with Section
401(a)(17)(B) of the Code. Annual compensation means compensation during the
plan year or such other consecutive 12-month period over which compensation is
otherwise determined under the plan (the determination period). If this is a
target benefit plan, then except as otherwise elected in Section 2.5 of this
amendment, for purposes of determining benefit accruals in a plan year
beginning after December 31, 2001, compensation for any prior determination
period shall be limited to $200,000. The cost-of-living adjustment in effect
for a calendar year applies to annual compensation for the determination period
that begins with or within such calendar year.

ARTICLE VIII

PLAN LOANS

Plan loans for owner-employees or shareholder-employees.
If the plan permits loans to be made to participants, then effective for plan
loans made after December 31, 2001, plan provisions prohibiting loans to any
owner-employee or shareholder-employee shall cease to apply.

  the lesser of:

	
   
	
   
	
   
	
   
	
   

	
   
	
   
	
  a.          $40,000,
  as adjusted for increases in the cost-of-living under Section 415(d) of the
  Code, or

	
   
	
   
	
   
	
   
	
   

	
   
	
   
	
  b.          100

  The
  compensation limit referred to in b. shall not apply to any contribution for
  medical benefits after separation from service (within the meaning of Section
  401(h) or Section 419A(f)(2) of the Code) which is otherwise treated as an
  annual addition.

ARTICLE X

MODIFICATION OF TOP-HEAVY RULES

	
  10.1
	
   
	
  Effective
  date. This Article shall apply for purposes of
  determining whether the plan is a top-heavy plan under Section 416(g) of the
  Code for plan years beginning after December 31, 2001, and whether the plan
  satisfies the minimum benefits requirements of Section 416(c) of the Code for
  such years. This Article amends the top-heavy provisions of the plan.

	
   
	
   
	
   

	
  10.2
	
   
	
  Determination
  of top-heavy status.

	
   
	
   
	
   

	
  10.2.1
	
   
	
  Key employee.
  Key employee means any employee or former employee (including any deceased
  employee) who at any time during the plan year that includes the
  determination date was an officer of the employer having annual compensation
  greater than $130,000 (as adjusted under Section 416(i)(1) of the Code for
  plan years beginning after December 31, 2002), a 5-percent owner of the
  employer, or a 1-percent owner of the employer having annual compensation of
  more than $150,000. For this purpose, annual compensation means compensation
  within the meaning of Section 415(c)(3) of the Code. The determination of who
  is a key employee will be made in accordance with Section 416(i)(1) of the
  Code and the applicable regulations and other guidance of general
  applicability issued thereunder.

	
   
	
   
	
   

	
  10.2.2
	
   
	
  Determination
  of present values and amounts. This Section 10.2.2
  shall apply for purposes of determining the present values of accrued
  benefits and the amounts of account balances of employees as of the
  determination date.

	
   
	
   
	
   
	
   
	
   

	
   
	
   
	
  a.
	
  Distributions
  during year ending on the determination date. The
  present values of accrued benefits and the amounts of account balances of an
  employee as of the determination date shall be increased by the distributions
  made with respect to the employee under the plan and any plan aggregated with
  the plan under Section 416(g)(2) of the Code during the 1-year period ending
  on the determination date. The preceding sentence shall also apply to
  distributions under a terminated plan which, had it not been terminated,
  would have been aggregated with the plan under Section 416(g)(2)(A)(i) of the
  Code. In the case of a distribution made for a reason other than separation
  from service, death, or disability, this provision shall be applied by
  substituting “5-year period” for “1-year period.”

	
   
	
   
	
   
	
   
	
   

	
   
	
   
	
  b.
	
  Employees
  not performing services during year ending on the determination date.
  The accrued benefits and accounts of any individual who has not performed
  services for the employer during the 1-year period ending on the
  determination date shall not be taken into account.

	
   
	
   
	
   
	
   
	
   

	
  10.3
	
   
	
  Minimum
  benefits.

	
   
	
   
	
   

	
  10.3.1
	
   
	
  Matching
  contributions. Employer matching contributions shall
  be taken into account for purposes of satisfying the minimum contribution
  requirements of Section 416(c)(2) of the Code and the plan. The preceding
  sentence shall apply with respect to matching contributions under the plan
  or, if the plan provides that the minimum contribution requirement shall be met
  in another plan, such other plan. Employer matching contributions that are
  used to satisfy the minimum contribution requirements shall be treated as
  matching contributions for purposes of the actual contribution percentage
  test and other requirements of Section 401(m) of the Code.

	
   
	
   
	
   

	
  10.3.2
	
   
	
  Contributions
  under other plans. The employer may provide, in an
  addendum to this amendment, that the minimum benefit requirement shall be met
  in another plan (including another plan that consists solely of a cash or
  deferred arrangement which meets the requirements of Section 401(k)(12) of
  the Code and matching contributions with respect to which the requirements of
  Section 401(m)(11) of the Code are met). The addendum should include the name
  of the other plan, the minimum benefit that will be provided under such other
  plan, and the employees who will receive the minimum benefit under such other
  plan.

ARTICLE XI

DIRECT ROLLOVERS

	
  11.1

  	
   
	
  Effective
  date. This Article shall apply to distributions made
  after December 31, 2001.

	
   
	
   
	
   

	
  11.2
	
   
	
  Modification
  of definition of eligible retirement plan. For
  purposes of the direct rollover provisions of the plan, an eligible
  retirement plan shall also mean an annuity contract described in Section
  403(b) of the Code and an eligible plan under Section 457(b) of the Code
  which is maintained by a state, political subdivision of a state, or any
  agency or instrumentality of a state or political subdivision of a state and
  which agrees to separately account for amounts transferred into such plan
  from this plan. The definition of eligible retirement plan shall also apply
  in the case of a 

4

EGTRRA - Employer

	
   
	
   
	
  distribution
  to a surviving spouse, or to a spouse or former spouse who is the alternate
  payee under a qualified domestic relation order, as defined in Section 414(p)
  of the Code.

	
   
	
   
	
   

	
  11.3
	
   
	
  Modification
  of definition of eligible rollover distribution to exclude hardship
  distributions. For purposes of the direct rollover
  provisions of the plan, any amount that is distributed on account of hardship
  shall not be an eligible rollover distribution and the distributee may not
  elect to have any portion of such a distribution paid directly to an eligible
  retirement plan.

	
   
	
   
	
   

	
  11.4
	
   
	
  Modification
  of definition of eligible rollover distribution to include after-tax employee
  contributions. For purposes of the direct rollover
  provisions in the plan, a portion of a distribution shall not fail to be an
  eligible rollover distribution merely because the portion consists of
  after-tax employee contributions which are not includible in gross income.
  However, such portion may be transferred only to an individual retirement
  account or annuity described in Section 408(a) or (b) of the Code, or to a
  qualified defined contribution plan described in Section 401(a) or 403(a) of
  the Code that agrees to separately account for amounts so transferred,
  including separately accounting for the portion of such distribution which is
  includible in gross income and the portion of such distribution which is not
  so includible.

ARTICLE XII

ROLLOVERS FROM OTHER PLANS

Rollovers from other plans. The employer,
operationally and on a nondiscriminatory basis, may limit the source of
rollover contributions that may be accepted by this plan.

ARTICLE XIII

REPEAL OF MULTIPLE USE TEST

Repeal of Multiple Use Test. The multiple use
test described in Treasury Regulation Section 1.401(m)-2 and the plan shall not
apply for plan years beginning after December 31, 2001.

ARTICLE XIV

ELECTIVE DEFERRALS

	
  14.1

  	
   
	
  Elective
  Deferrals - Contribution Limitation. No participant
  shall be permitted to have elective deferrals made under this plan, or any
  other qualified plan maintained by the employer during any taxable year, in
  excess of the dollar limitation contained in Section 402(g) of the Code in
  effect for such taxable year, except to the extent permitted under Article VI
  of this amendment and Section 414(v) of the Code, if applicable.

	
   
	
   
	
   

	
  14.2
	
   
	
  Maximum
  Salary Reduction Contributions for SIMPLE plans. If
  this is a SIMPLE 401(k) plan, then except to the extent permitted under
  Article VI of this amendment and Section 414(v) of the Code, if applicable,
  the maximum salary reduction contribution that can be made to this plan is
  the amount determined under Section 408(p)(2)(A)(ii) of the Code for the
  calendar year.

ARTICLE XV

SAFE HARBOR PLAN PROVISIONS

Modification of Top-Heavy Rules. The top-heavy
requirements of Section 416 of the Code and the plan shall not apply in any
year beginning after December 31, 2001, in which the plan consists solely of a
cash or deferred arrangement which meets the requirements of Section 401(k)(12)
of the Code and matching contributions with respect to which the requirements
of Section 401(m)(11) of the Code are met.

ARTICLE XVI

DISTRIBUTION UPON SEVERANCE OF EMPLOYMENT

	
  16.1

  	
   
	
  Effective
  date. This Article shall apply for distributions and
  transactions made after December 31, 2001, regardless of when the severance
  of employment occurred.

	
   
	
   
	
   

	
  16.2
	
   
	
  New
  distributable event. A participant’s elective
  deferrals, qualified nonelective contributions, qualified matching
  contributions, and earnings attributable to these contributions shall be
  distributed on account of the participant’s severance from employment.
  However, such a distribution shall be subject to the other provisions of the

     6.
Shares Subject to Plan, Limitations on Grants and Exercise Price. Subject
to adjustment by the operation of Section 15 hereof:

	 	     (a) The
maximum number of Shares that may be issued with respect to Awards made  under the Plan
is 296,240 Shares, no more than 97,759 (one-third) of  which may be issued
pursuant to Awards granted in the form of Restricted Shares.  The number of Shares that
may be granted under the Plan to any Participant  during any year under all forms of
Awards will not exceed 30,000 Shares.

	 	     (b) The
Shares with respect to which Awards may be made under the Plan may either be  authorized
and unissued Shares or issued Shares heretofore or hereafter  reacquired and held as
treasury Shares. Any Award that expires, terminates or is  surrendered for cancellation,
or with respect to Restricted Shares, which is  forfeited (so long as any cash dividends
paid on such Shares are also  forfeited), may be subject to new Awards under the Plan
with respect to the  number of Shares as to which a termination or forfeiture has
occurred.  Additionally, Shares that are withheld by the Company or delivered by the
Participant to the Company in order to satisfy payment of the Exercise Price or  any tax
withholding obligation and Shares granted pursuant to an Award Agreement  which is
subsequently settled in cash rather than Shares, may be subject to new  Awards under the
Plan.

	 	     (c) Notwithstanding
any other provision under the Plan, the Exercise Price for any  Incentive Stock Option
awarded under the Plan may not be less than the Market  Value of the Shares.

     7.
General Terms and Conditions of Options.

	 	     (a) The
Board of Directors, with input from the Compensation Committee will have  full and
complete authority and discretion, except as expressly limited by the  Plan, to grant
Options and to prescribe the terms and conditions (which need not  be identical among
Participants) of the Options. Each Option will be evidenced  by an Award Agreement that
will specify: (i) the Exercise Price, (ii) the  number of Shares subject to the
Option, (iii) the expiration date of the Option,  (iv) the manner, time and rate
(cumulative or otherwise) of exercise of the  Option, (v) the restrictions, if any,
to be placed upon the Option or upon  Shares that may be issued upon exercise of the
Option, (vi) the conditions,  if any, under which a Participant may transfer or
assign Options, and (vii) any  other terms and conditions as the Board of Directors, in
its sole discretion,  may determine.

4

	 	     (b) The
Board of Directors shall not, without the further approval of the  shareholders of the
Company, authorize the amendment of any outstanding Option  Award Agreement to reduce the
Exercise Price. Furthermore, no Option shall be  cancelled and replaced with an Option
having a lower Exercise Price without  further approval of the shareholders of the
Company.

     8.
Exercise of Options.

	 	     (a) Except
as provided in Section 17, an Option granted under the Plan will be  exercisable only by
the Participant, and except as provided in Section 9 of the  Plan, no Option may be
exercised unless at the time the Participant exercises  the Option, the Participant has
maintained Continuous Service since the date of  the grant of the Option.

	 	     (b) To
exercise an Option under the Plan, the Participant must give written notice  to the
Company specifying the number of Shares with respect to which the  Participant elects to
exercise the Option together with full payment of the  Exercise Price. The date of
exercise will be the date on which the notice is  received by the Company. Payment may be
made either (i) in cash (including  check, bank draft or money order), (ii) by
tendering Shares already  owned by the Participant for at least six (6) months prior
to the date of  exercise and having a Market Value on the date of exercise equal to the
Exercise  Price, or (iii) by any other means determined by the Board of Directors in its
sole discretion.

     9.
Termination of Options. Unless otherwise specifically provided  elsewhere
in the Plan or by the Board of Directors in the Award Agreement or any  amendment
thereto, Options will terminate as provided in this Section.

	 	     (a) Unless
sooner terminated under the provisions of this Section, Options will  expire on the
earlier of the date specified in the Award Agreement or the  expiration of ten (10) years
from the date of grant.

	 	     (b) If
the Continuous Service of a Participant is terminated for reason of  Retirement, the
Participant may exercise all Options that are vested or that  vest in full within the
period of thirty-six months (36) months immediately  succeeding the Participant’s
Retirement. Any unvested Options remaining at  the end of the 36-month post-retirement
period will be forfeited by the  Participant.

	 	     (c) If
the Continuous Service of a Participant is terminated for Cause, all rights  under any
Options granted to the Participant will terminate immediately upon the  Participant’s
cessation of Continuous Service, and the Participant will  (unless the Board of
Directors, in its sole discretion, waives this requirement)  repay to the Company within
ten (10) days the amount of any gain realized by the  Participant upon any exercise of an
Option, awarded under the Plan, within the  90-day period prior to the cessation of
Continuous Service.

	 	     (d) If
the Continuous Service of a Participant is terminated voluntarily by the  Participant for
any reason other than death, Disability, or Retirement, the  Participant may exercise
outstanding Options to the extent that the Participant  was entitled to exercise the
Options at the date of cessation of Continuous  Service, but only within the period of
three (3) months immediately  succeeding the Participant’s cessation of
Continuous Service, and in no  event after the applicable expiration dates of the Options.

	 	     (e) If
the Continuous Service of a Participant is terminated by the Company without  Cause, the
Participant may exercise outstanding Options to the extent that the  Participant was
entitled to exercise the Options at the date of cessation of  Continuous Service, but
only within the period of three (3) months immediately  succeeding the Participant’s
cessation of Continuous Service, and in no  event after the applicable expiration dates
of the Options; provided, however,  that if a Participant is terminated by the Company
without Cause within twelve  months after a Change in Control, such Participant may
exercise outstanding  Options to the extent he or she was entitled to exercise the
Options at the date  of cessation of Continuous Service, within the period of

5

	 	one (1)
year  immediately succeeding the cessation of Continuous Service but in no event after
the applicable expiration dates of the Options.

	 	     (f) In
the event of the Participant’s death or Disability, all Options  heretofore granted
and not fully exercisable will become exercisable in full and  the Participant or the
Participant’s beneficiary, as the case may be, may  exercise such Options within the
period of one (1) year immediately succeeding  the Participant’s cessation of
Continuous Service by reason of death or  Disability, and in no event after the
applicable expiration date of the Options.

	 	     (g) Notwithstanding
the provisions of the foregoing paragraphs of this Section 9,  the Board of Directors
may, in its sole discretion, establish different terms  and conditions pertaining to the
effect of the cessation of Continuous Service,  to the extent permitted by applicable
federal and state law. Additionally,  notwithstanding the provisions of the foregoing
paragraphs of this Section 9,  the Board of Directors may, in its sole discretion, allow
the exercise of an  expired Option if the Board of Directors determines that: (i) the
expiration was  solely the result of the Company’s inability to execute the exercise
of an  Option due to conditions beyond the Company’s control, and (ii) the
Participant made valid and reasonable efforts to exercise the Award. In the  event the
Board of Directors makes such a determination, the Company shall allow  the exercise to
occur as promptly as possible following its receipt of exercise  instructions subsequent
to such determination.

     10.
Restrictive Covenants. In its discretion, the Board of Directors  may
condition the grant of any Award under the Plan upon the Participant  agreeing to
reasonable covenants in favor of the Company and/or any Affiliate  (including, without
limitation, covenants not to compete, not to solicit  employees and customers, and not to
disclose confidential information) that may  have effect following the termination of
employment with the Company or any  Affiliate.

     11.
Incentive and Non-Qualified Stock Options.

	 	     (a) Incentive
Stock Options may be granted only to Participants who are Employees.  Any provisions of
the Plan to the contrary notwithstanding, (i) no  Incentive Stock Option will be
granted more than ten (10) years from the earlier  of the date the Plan is adopted by the
Board of Directors of the Company or  approved by the Company’s shareholders, (ii)
no Incentive Stock Option will  be exercisable more than ten (10) years from the date the
Incentive Stock Option  is granted, (iii) the Exercise Price of any Incentive Stock
Option will not  be less than the Market Value per Share on the date such Incentive Stock
Option  is granted, (iv) any Incentive Stock Option will not be transferable by the
Participant to whom such Incentive Stock Option is granted other than by will or  the
laws of descent and distribution and will be exercisable during the  Participant’s
lifetime only by such Participant, (v) no Incentive  Stock Option will be granted
that would permit a Participant to acquire, through  the exercise of Incentive Stock
Options in any calendar year, under all plans of  the Company and its Affiliates, Shares
having an aggregate Market Value  (determined as of the time any Incentive Stock Option
is granted) in excess of  $100,000 (determined by assuming that the Participant will
exercise each  Incentive Stock Option on the date that such Option first becomes
exercisable),  and (vi) no Incentive Stock Option may be exercised more than three (3)
months  after the Participant’s cessation of Continuous Service (one (1) year in
the case of Disability) for any reason other than death. Notwithstanding the  foregoing,
in the case of any Participant who, at the date of grant, owns shares  possessing more
than 10% of the total combined voting power of all classes of  capital stock of the
Company or any Affiliate, the Exercise Price of any  Incentive Stock Option will not be
less than 110% of the Market Value per Share  on the date such Incentive Stock Option is
granted and such Incentive Stock  Option shall not be exercisable more than five years
from the date such  Incentive Stock Option is granted.

	 	     (b) Notwithstanding
any other provisions of the Plan, if for any reason an Option  granted under the Plan
that is intended to be an Incentive Stock Option fails to  qualify as an Incentive Stock
Option, such Option will be deemed to be a  Non-Qualified Stock Option, and such Option
will be deemed to be fully  authorized and validly issued under the Plan.

     12.
Terms and Conditions of Restricted Shares. The Board of Directors  will
have full and complete authority, subject to the limitations of the Plan,  to grant
Awards of Restricted Shares and to prescribe the terms and conditions  (which need not be
identical among Participants) in respect of the Awards.  Unless the Board of Directors
otherwise specifically provides in the Award  Agreement, an Award of Restricted Shares
will be subject to the following  provisions:

	 	     (a) At
the time of an Award of Restricted Shares, the Board of Directors will  establish for
each Participant a Restricted Period during which, or at the  expiration of which, the
Restricted Shares will vest. Subject to paragraph (e)  of this Section, the Participant
will have all the rights of a shareholder with  respect to the Restricted Shares,
including, but not limited to, the right to  receive all dividends paid on the Restricted
Shares and the right to vote the  Restricted Shares. The Board of Directors will have the
authority, in its  discretion, to accelerate the time at which any or all of the
restrictions will  lapse with respect to any Restricted Shares prior to the expiration of
the  Restricted Period, or to remove any or all restrictions, whenever it may  determine
that such action is appropriate by reason of changes in applicable tax  or other laws or
other changes in circumstances occurring after the commencement  of the Restricted Period.

	 	     (b) Subject
to Section 16, if a Participant ceases Continuous Service for any reason  other than
death or disability, before the Restricted Shares have vested, a  Participant’s
rights with respect to the unvested portion of the Restricted  Shares will terminate and
be returned to the Company.

	 	     (c) Subject
to Section 16, if a Participant ceases Continuous Service by reason of  death or
Disability before any Restricted Period has expired, the Restricted  Shares will become
fully vested.

	 	     (d) Each
certificate issued in respect to Restricted Shares will be registered in  the name of the
Participant and deposited by the Participant, together with a  stock power endorsed in
blank, with the Company and will bear a legend referring  to the terms, conditions and
restrictions applicable to such shares.

	 	     (e) At
the time of an Award of Restricted Shares, the Participant will enter into an  Award
Agreement with the Company in a form specified by the Board of Directors  agreeing to the
terms and conditions of the Award.

	 	     (f) At
the expiration of the restrictions imposed by this Section, the Company will  redeliver
to the Participant the certificate(s) and stock powers, deposited with  the Company
pursuant to paragraph (d) of this Section and the Shares represented  by the
certificate(s) will be free of all restrictions.

	 	     (g) No
Award of Restricted Shares may be assigned, transferred or encumbered.

     13.
Terms and Conditions of Stock Appreciation Rights. The  Board of
Directors will have full and complete authority, subject to the  limitations of the Plan,
to grant Awards of Stock Appreciation Rights and to  prescribe the terms and conditions
(which need not be identical among  Participants) in respect of the Awards. Unless the
Board of Directors otherwise  specifically provides in the Award Agreement, an Award of
Stock Appreciation  Rights will be subject to the following provisions:

	 	     (a) The
Board of Directors may grant a Stock Appreciation Right or “SAR” under this
Plan. A SAR shall provide a Participant with the right to receive a  payment, in cash
and/or Common Stock, equal to the excess of the Fair Market  Value of a specified number
of shares of Common Stock on the date the SAR is  exercised over the Fair Market Value of
a share of Common Stock on the date the  SAR was granted (the “base price”) as
set forth in the applicable  Award Agreement.

7

	 	     (b) In
the case of a SAR granted retroactively in tandem with or as a substitution  for another
Award, the base price may be no lower than the Fair Market Value of  a share of Common
Stock on the date such other Award was granted.

	 	     (c) The
maximum term of a SAR shall be ten (10) years. The Board of Directors may  also grant
limited SARs, which are exercisable only upon a Change in Control or  other specified
event and may be payable based on the spread between the base  price of the SAR and the
Fair Market Value of a share of Common Stock during a  specified period or at a specified
time within a specified period before, after  or including the date of the Change in
Control or other specified event.

	 	     (d) If
the Continuous Service of a Participant is terminated for reason of  Retirement, the
Participant may exercise any SAR that is vested or that vest in  full within the period
of thirty-six months (36) months immediately succeeding  the Participant’s
Retirement. Any unvested SAR remaining at the end of the  36-month post-retirement period
will be forfeited by the Participant.

	 	     (e) If
the Continuous Service of a Participant is terminated for Cause, all rights  under any
SAR granted to the Participant will terminate immediately upon the  Participant’s
cessation of Continuous Service, and the Participant will  (unless the Board of
Directors, in its sole discretion, waives this requirement)  repay to the Company within
ten (10) days the amount of any gain realized by the  Participant upon any exercise of an
SAR awarded under the Plan, within the  90-day period prior to the cessation of
Continuous Service.

	 	     (f) If
the Continuous Service of a Participant is terminated voluntarily by the  Participant for
any reason other than death, Disability, or Retirement, the  Participant may exercise any
outstanding SAR to the extent that the Participant  was entitled to exercise the SAR at
the date of cessation of Continuous Service,  but only within the period of three (3)
months immediately succeeding the  Participant’s cessation of Continuous Service,
and in no event after the  applicable expiration dates of the SAR.

	 	     (g) If
the Continuous Service of a Participant is terminated by the Company without  Cause, the
Participant may exercise any outstanding SAR to the extent that the  Participant was
entitled to exercise the SAR at the date of cessation of  Continuous Service, but only
within the period of three (3) months immediately  succeeding the Participant’s
cessation of Continuous Service, and in no  event after the applicable expiration dates
of the SAR; provided, however, that  if a Participant is terminated by the Company
without Cause within twelve months  after a Change in Control, such Participant may
exercise any outstanding SAR to  the extent he or she was entitled to exercise the SAR at
the date of cessation  of Continuous Service, within the period of one (1) year
immediately succeeding  the cessation of Continuous Service but in no event after the
applicable  expiration dates of the SAR.

	 	     (h) In
the event of the Participant’s death or Disability, any SAR heretofore  granted and
not fully exercisable will become exercisable in full and the  Participant or the
Participant’s beneficiary, as the case may be, may  exercise such SAR within the
period of one (1) year immediately succeeding the  Participant’s cessation of
Continuous Service by reason of death or  Disability, and in no event after the
applicable expiration date of the SAR.

	 	     (i) Notwithstanding
the provisions of the foregoing paragraphs of this Section 13,  the Board of Directors
may, in its sole discretion, establish different terms  and conditions pertaining to the
effect of the cessation of Continuous Service,  to the extent permitted by applicable
federal and state law. Additionally,  notwithstanding the provisions of the foregoing
paragraphs of this Section 13,  the Board of Directors may, in its sole discretion, allow
the exercise of an  expired SAR if the Board of Directors determines that: (i) the
expiration was  solely the result of the Company’s inability to execute the exercise
of an  SAR due to conditions beyond the Company’s control, and (ii) the  Participant
made valid and reasonable efforts to exercise the Award. In the  event the Board of
Directors makes such a determination, the Company shall allow  the exercise to occur as
promptly as possible following its receipt of exercise  instructions subsequent to such
determination.

     14.
Adjustments Upon Changes in Capitalization. In the event of  any
change in the outstanding Shares subsequent to the effective date of the  Plan by reason
of any reorganization, recapitalization, stock split, stock  dividend, combination or
exchange of shares, merger, consolidation or any change  in the corporate structure or
Shares of the Company, the maximum aggregate  number and class of Shares as to which
Awards may be granted under the Plan and  the number and class of Shares, and the
exercise price of Options, with respect  to which Awards theretofore have been granted
under the Plan will be  appropriately adjusted by the Board of Directors to prevent the
dilution or  diminution of Awards. The Board of Director’s determination with
respect to  any adjustments will be conclusive. Any Shares or other securities received,
as  a result of any of the foregoing, by a Participant with respect to Restricted  Shares
will be subject to the same restrictions and the certificate(s) or other  instruments
representing or evidencing the Shares or other securities will be  legended and deposited
with the Company in the manner provided in Section 12 of  this Agreement.

     15.
Effect of Reorganization. Unless otherwise provided by the  Board of
Directors in the Award Agreement, Awards will be affected by a  Reorganization as follows:

	 	     (a) If
the Reorganization is a dissolution or liquidation of the Company then  (i) the
restrictions on Restricted Shares will lapse and (ii) each  outstanding Option Award
will terminate, but each Participant to whom the Option  was granted will have the right,
immediately prior to the dissolution or  liquidation, to exercise the Option in full,
notwithstanding the provisions of  Section 11, and the Company will notify each
Participant of such right  within a reasonable period of time prior to any dissolution or
liquidation.

	 	     (b) If
the Reorganization is a merger or consolidation, upon the effective date of  the
Reorganization (i) each Participant will be entitled, upon exercise of  an Option in
accordance with all of the terms and conditions of the Plan, to  receive in lieu of
Shares, shares or other securities or consideration as the  holders of Shares are
entitled to receive pursuant to the terms of the  Reorganization; and (ii) each
holder of Restricted Shares will be entitled  to receive shares or other securities as
the holders of Shares received which  will be subject to the restrictions set forth in
Section 12 (unless the  Board of Directors accelerates the lapse of such
restrictions) and the  certificate(s) or other instruments representing or evidencing the
shares or  other securities shall be legended and deposited with the Company in the
manner  provided in Section 12 of this Plan.

     The
adjustments contained in this Section and the manner of application of such
provisions will be determined solely by the Board of Directors.

     16.
Effect of Change of Control.

	 	     (a) If
the Continuous Service of any Participant of the Company or any Affiliate is
involuntarily terminated, for whatever reason, at any time within twelve (12)  months
after a Change in Control, unless the Board of Directors has otherwise  provided in the
Award Agreement, (i) any Restricted Period with respect to an  Award of Restricted Shares
will lapse upon the Participant’s termination of  Continuous Service and all
Restricted Shares will become fully vested in the  Participant to whom the Award was made.

	 	     (b) If
a tender offer or exchange offer for Shares (other than such an offer by the  Company) is
commenced, or if a Change in Control occurs, unless the Board of  Directors has otherwise
provided in the Award Agreement, all Option Awards  theretofore granted and not fully
exercisable will become exercisable in full  upon the happening of such event and will
remain exercisable in accordance with  their terms; provided, however, that no Option
which has previously been  exercised or otherwise terminated will become exercisable.

     17.
Assignments and Transfers. No Award nor any right or  interest of a
Participant in any Award under the Plan may be assigned,  encumbered or transferred
otherwise than by will or the laws of descent and  distribution. Notwithstanding the
foregoing, the Board of Directors may, in its  sole discretion, set forth in an Award
Agreement at the time of grant or  thereafter, that the Award (other than Incentive Stock
Options) may be  transferred to members of the Participant’s immediate family, to
one or  more trusts solely for the benefit of such immediate family members and to
partnerships in which such family members or trusts are the only partners. For  this
purpose, immediate family means the Participant’s spouse, parents,  children,
step-children, grandchildren and legal dependents. Any transfer of an  Award under this
provision will not be effective until notice of such transfer  is delivered to the
Company.

     18.
Employee Rights Under the Plan. No officer, Director,  Employee or
other person will have a right to be selected as a Participant nor,  having been so
selected, to be selected again as a Participant, and no officer,  Director, Employee or
other person will have any claim or right to be granted an  Award under the Plan or under
any other incentive or similar plan of the Company  or any Affiliate. Neither the Plan
nor any action taken under the Plan will be  construed as giving any Employee any right
to be retained in the employ of the  Company or any Affiliate.

     19.
Delivery and Registration of Shares. The Company’s  obligation
to deliver Shares with respect to an Award will, if the Board of  Directors requests, be
conditioned upon the receipt of a representation as to  the investment intention of the
Participant to whom such Shares are to be  delivered, in such form as the Board of
Directors will determine to be necessary  or advisable to comply with the provisions of
the Securities Act or any other  applicable federal or state securities laws. It may be
provided that any  representation requirement will become inoperative upon a registration
of the  Shares or other action eliminating the necessity of the representation under the
Securities Act or other state securities laws. The Company will not be required  to
deliver any Shares under the Plan prior to (a) the admission of such  Shares to
listing on any stock exchange or system on which Shares may then be  listed, and (b) the
completion of any registration or other qualification  of the Shares under any state or
federal law, rule or regulation, as the Company  determines to be necessary or advisable.

     20.
Withholding Tax. Prior to the delivery of any Shares or  cash
pursuant to an Award, the Company has the right and power to deduct or  withhold, or
require the Participant to remit to the Company, an amount  sufficient to satisfy all
applicable tax withholding requirements. The Board of  Directors, in its sole discretion
and pursuant to such procedures as it may  specify from time to time, may permit or
require a Participant to satisfy all or  part of the tax withholding obligations in
connection with an Award by (a)  having the Company withhold otherwise deliverable
Shares, or (b) delivering  to the Company Shares already owned for a period of at
least six months and  having a value equal to the amount required to be withheld. The
amount of the  withholding requirement will be deemed to include any amount that the
Board of  Directors determines, not to exceed the amount determined by using the maximum
federal, state or local marginal income tax rates applicable to the Participant  with
respect to the Award on the date that the amount of tax to be withheld is  to be
determined for these purposes. For these purposes, the value of the Shares  to be
withheld or delivered will be equal to the Market Value as of the date  that the taxes
are required to be withheld.

     21.
Termination, Amendment and Modification of Plan. The Board  may at
any time terminate, and may at any time and from time to time and in any  respect amend
or modify the Plan; provided, however, that to the extent  necessary and desirable to
comply with Rule 16b-3 under the Exchange Act or  Code section 422 (or any
other applicable law or regulation, including  requirements of any stock exchange or
quotation system on which the  Company’s common stock is listed or quoted),
shareholder approval of any  Plan amendment will be obtained in the manner and to the
degree as is required  by the applicable law or regulation; and provided further, that no
termination,  amendment or modification of the Plan will in any manner affect any Award
theretofore granted pursuant to the Plan without the consent of the Participant  to whom
the Award was granted or the transferee of the Award.

     22.
Effective Date and Term of Plan.  The Plan will become effective  upon its
adoption by the Board of Directors of the Company. Unless sooner  terminated pursuant to
Section 21, no further Awards may be made under the Plan  after ten (10) years from the
effective date of the Plan.

     23.
Governing Law. The Plan and Award Agreements will be construed in
accordance with and governed by the internal laws of the State of Delaware.

     25.
Re-pricing of Options.  Nothing in this Plan shall  permit
the re-pricing of any outstanding options other than (a) with the prior  approval of the
Company’s shareholders, or (b) pursuant to Sections 14 and  15. The foregoing
restriction shall also apply to any other transaction which  would be treated as a
re-pricing of outstanding options under generally accepted  accounting principles.
