the Committee, at any time and from time to time, may grant Shares of Restricted
Stock to Participants in such amounts as the Committee shall determine.

     a) Subject to the terms hereof, the Committee shall impose such conditions
and/or restrictions on any Shares of Restricted Stock granted pursuant to the
Plan as it may deem advisable and as are expressly set forth in the Award
Agreement including, without limitation, a requirement that Participants pay a
stipulated purchase price for each Share of Restricted Stock, restrictions based

and/or individual), time-based restrictions, and/or restrictions under
applicable federal or state securities laws.

     b) The Company shall retain the certificates representing Shares of

and/or restrictions applicable to such Shares have been satisfied. The
Participant shall execute appropriate stock powers in blank and such other
documents as the Committee shall prescribe.




     c) Subject to restrictions under applicable law or as may be imposed by the
Company, Restricted Shares covered by each Award made under the Plan shall
become freely transferable by the Participant after the last day of the
applicable Period of Restriction.

6.5 Voting Rights. During the Period of Restriction, subject to any limitations
imposed under the By-laws of the Company, Participants holding Shares of
Restricted Stock granted hereunder may exercise full voting rights with respect
to those Shares.

6.6 Dividends and Other Distributions. During the Period of Restriction,
Participants holding Shares of Restricted Stock granted hereunder may be
credited with regular dividends paid with respect to the underlying Shares while
they are so held. The Committee may apply any restrictions to the dividends that
the Committee deems appropriate and as are expressly set forth in the Award
Agreement. Without limiting the generality of the preceding sentence, if the
grant or vesting of Restricted Shares granted to a Named Executive Officer is
designed to comply with the requirements of the Performance-Based Exception, the
Committee may apply any restrictions it deems appropriate to the payment of
dividends declared with respect to such Restricted Shares, such that the
dividends and/or the Restricted Shares maintain eligibility for the
Performance-Based Exception.


Article 7:  Termination of Service

Each Award Agreement shall set forth the effect that Termination of Service
shall have upon that Award. Such provisions shall be determined in the sole
discretion of the Committee, need not be uniform among all Awards issued
pursuant to the Plan, and may reflect distinctions based on the reasons for
Termination of Service; provided, however, that the following shall
automatically apply to the extent different provisions are not expressly set
forth in a Participant's Award Agreement:

     a) Upon a Termination of Service for any reason other than death,
retirement or Disability, all unvested Restricted Shares shall be forfeited as
of the termination date.

     b) Upon a Termination of Service as a result of the Participant's death,
retirement or Disability, all unvested Restricted Shares shall vest as of the
termination date.


Article 8:  Restrictions on Shares

All Shares issued pursuant to Awards granted hereunder, and a Participant's
right to receive Shares upon vesting of an Award, shall be subject to all
applicable restrictions contained in the Company's By-laws, shareholders
agreement or insider trading policy, and any other restrictions imposed by the
Committee, including, without limitation, restrictions under applicable
securities laws, under the requirements of any stock exchange or market upon
which such Shares are then listed and/or traded, and restrictions under any blue
sky or state securities laws applicable to such Shares.





Article 9:  Performance Measures

If an Award is subject to Code Section 162(m) and the Committee determines that
such Award should be designed to comply with the Performance-Based Exception,
the performance measure(s), the attainment of which determine the degree of
vesting, to be used for purposes of such Awards shall be chosen from among
earnings per share, economic value added, market share (actual or targeted
growth), net income (before or after taxes), operating income, return on assets
(actual or targeted growth), return on capital (actual or targeted growth),
return on equity (actual or targeted growth), return on investment (actual or
targeted growth), gross or net underwriting results, revenue (actual or targeted
growth), share price, stock price growth, total shareholder return, or such
other performance measures as are duly approved by the Committee and the
Company's shareholders.

Article 10:  Beneficiary Designation

Subject to the terms and conditions of the Plan and the applicable Award
Agreement, each Participant may, from time to time, name any beneficiary or
beneficiaries (who may be named contingently or successively) to whom Shares
under the Plan are to be transferred in the event of the Participant's death.
Each such designation shall revoke all prior designations by the same
Participant, shall be in a form prescribed by the Company, and will be effective
only when filed by the Participant in writing during the Participant's lifetime
with the party chosen by the Company, from time to time, to administer the Plan.
In the absence of any such designation, Shares shall be paid to the
Participant's estate following his death.

with the Group at any time, or

     b) confer upon any Participant any right to continue in the service of any
member of the Group as an Employee, Director or Consultant.

immediately lapse




Article 13:  Amendment or Termination

The Board may at any time and from time to time amend or terminate the Plan or
any Award hereunder in whole or in part; provided, however, that no amendment
which requires shareholder approval in order for the Plan to continue to comply
with any applicable tax or securities laws or regulations, or the rules of any
securities exchange on which the securities of the Company are listed, shall be
effective unless such amendment shall be approved by the requisite vote of
shareholders of the Company entitled to vote thereon; provided further that no
such amendment or termination shall adversely affect any Award hereunder without
the consent of the Participant.

require a Participant to remit to the Company, an amount sufficient to satisfy
any taxes required by federal, state, or local law or regulation to be withheld
with respect to any taxable event arising in connection with an Award.

14.2 Share Withholding. Participants may elect, subject to the approval of the
Committee, to satisfy all or part of such withholding requirement by having the
Company withhold Shares having a Fair Market Value equal to the minimum
statutory total tax which could be imposed on the transaction. All such
elections shall be irrevocable, made in writing, signed by the Participant, and
shall be subject to any restrictions or limitations that the Committee, in its
sole discretion, deems appropriate.

Article 15:  Indemnification

Each person who is or shall have been a member of the Committee, or of the
Board, shall be indemnified and held harmless by the Company to the fullest
extent permitted by applicable law against and from any loss, cost, liability,
or expense that may be imposed upon or reasonably incurred by him or her in
connection with or resulting from any claim, action, suit, or proceeding to
which he or she may be a party or in which he or she may be involved by reason
of any action taken or failure to act under the Plan and against and from any
and all amounts paid by him or her in settlement thereof, with the Company's
approval, or paid by him or her in satisfaction of any judgment in any such
action, suit, or proceeding against him or her, provided he or she shall give
the Company an opportunity, at its own expense, to handle and defend the same
before he or she undertakes to handle and defend it on his or her own behalf.
The foregoing right of indemnification is subject to the person having been
successful in the legal proceedings or having acted in good faith and what is
reasonably believed to be a lawful manner in the Company's best interests. The
foregoing right of indemnification shall not be exclusive of any other rights of
indemnification to which such persons may be entitled under the Company's
Articles of Incorporation or Bylaws, as a matter of law, or otherwise, or any
power that the Company may have to indemnify them or hold them harmless.




Article 16:  Successors

All obligations of the Company under the Plan with respect to Awards granted

and/or assets of the Company.
