                     Award of Restricted Performance Shares

2.1 Award of Restricted Performance Shares. Effective as of the Date of Grant,
the Company awards to Participant the right to receive, after and to the extent
the Forfeiture Restrictions lapse, the number of Common Shares set forth on
Appendix A of this Agreement, subject to certain restrictions and shall be
herein referred to as the "Restricted Performance Shares." The rights awarded to
Participant pursuant to this Agreement shall be implemented by a credit to a
bookkeeping account maintained by the Company evidencing the accrual to
Participant of unsecured and unfunded rights to receive the Restricted
Performance Shares, which rights shall be subject to the terms, conditions, and
restrictions set forth in this Agreement and the Plan. Participant hereby
accepts the Restricted Performance Shares and agrees with respect thereto to the
terms and conditions set forth in the Agreement and the Plan.

2.2 Subsequent Awards. In the sole discretion of the Company, subsequent grants
of Restricted Performance Shares to Participant, if any, may be evidenced by
amending Appendix A of this Agreement to reflect such subsequent grant. Any such
subsequent grant of Restricted Performance Shares shall be issued upon
acceptance by Participant and upon satisfaction of the conditions of this
Agreement and the Plan. Participant shall accept any such subsequent grant of
Restricted Performance Shares when issued and agree with respect thereto to the
terms and conditions set forth in the Agreement and the Plan. Regardless of the
number of subsequent grants of Restricted Performance Shares, if any, evidenced
by this Agreement, this Agreement shall be interpreted to apply separately to
each grant of Restricted Performance Shares.

                                      III.
                             Forfeiture Restrictions

3.1      Forfeiture Restrictions.

(a) The Restricted Performance Shares may not be sold, assigned, pledged,
exchanged, hypothecated or otherwise transferred, encumbered or disposed of to
the extent then subject to the Forfeiture Restrictions (as hereinafter defined).
In the event of termination of Participant's Service for reasons other than
death or Disability, Participant shall, for no consideration, forfeit to the
Company all Restricted Performance Shares to the extent then subject to the
Forfeiture Restrictions. In addition, in the event the Company's Total
Shareholder Return over the Performance Period does not equal or exceed the 75th
percentile ranking compared to the Total Shareholder Return of the Peer
Companies, Participant shall, for no consideration, forfeit to the Company the
number of Restricted Performance Shares that do not Vest pursuant to the
provisions of Section 4.1. The prohibition against transfer and the obligation
to forfeit and surrender Restricted Performance Shares to the Company upon (i)
termination of Service for reasons other than death or Disability or (ii) the
Company's Total Shareholder Return over the Performance Period being less than
the 75th percentile ranking compared to the Total Shareholder Return of the Peer
Companies are herein referred to as the "Forfeiture Restrictions."

(b) The Forfeiture Restrictions shall be binding upon and enforceable against
any transferee of Restricted Performance Shares. The prohibitions of this
Section 3.1 shall not apply to the transfer of Restricted Performance Shares
pursuant to a plan of reorganization of the Company, but the stock, securities
or other property received in exchange therefore shall also become subject to
the Forfeiture Restrictions and provisions governing the lapsing of such
Forfeiture Restrictions applicable to the original Restricted Performance Shares
for all purposes of this Agreement.

                                       IV.
                                     Vesting

4.1 Vesting/Lapse of Forfeiture Restrictions. As soon as administratively
practicable after the last day of the Performance Period, the Committee shall
calculate the Total Shareholder Return for the Company and each Peer Company. At
such time and based on the percentile ranking of the Company's Total Shareholder
Return over the Performance Period compared to the Total Shareholder Return of
the Peer Companies, the Restricted Performance Shares shall Vest in accordance
with the following schedule:

Percentile Ranking of Company's Total
 Shareholder Return Compared              Percentage of Restricted Performance
       to Peer Companies                            Shares Vesting
       -----------------                            --------------
 At or above 75th                                        100%
 At or above 50th but less than 75th      Interpolated percentage between
                                                       20% and 100%
Below 50th 0%                                             0%

The interpolated percentage referred to in the schedule above shall be
determined by increasing the 20% Vesting percentage fora median percentile
ranking by 3.2% for each whole percentile ranking above the 50th percentile and
rounding the result up to the nearest whole percentage. To illustrate, if the
Company's Total Shareholder Return over the Performance Period ranks in the 52nd
percentile compared to the Total Shareholder Return of the Peer Companies, the
Vesting percentage shall be 27%, which is 26.4% (20% plus 6.4%) rounded up to
the nearest whole percentage.

Notwithstanding any provision of this Section 4.1 to the contrary and except as
provided in Section 4.2 and Section 4.3, no Restricted Performance Shares shall
Vest if Participant's Service is terminated prior to the last day of the
Performance Period for reasons other than death or Disability.




4.2 Acceleration of Vesting. In the event of a Change in Control while
Participant is in the Service of the Company or a Subsidiary, all of the
Restricted Performance Shares shall Vest as of the effective date of such Change
in Control.

4.3      Effect of Termination of Service on Vesting.

(a) Upon termination of Participant's Service for any reason other than death or
Disability, the Restricted Performance Shares shall be immediately forfeited to
the extent not then Vested.

(b) Upon termination of Participant's Service by reason of death or Disability,
the Restricted Performance Shares shall not be immediately forfeited, but rather
may become Vested as provided in Section 4.1 based on the Company's Total
Shareholder Return over the Performance Period.

                                       V.
                    Delivery of Restricted Performance Shares

5.1 Delivery of Restricted Performance Shares. As soon as practicable after the
Restricted Performance Shares become Vested, and subject to the tax withholding
referred to in Section 7.4, the Company shall deliver to Participant stock
certificates issued in Participant's name for the number of such Vested
Restricted Performance Shares.

                                       VI.
            Status of Restricted Performance Shares and Restrictions

6.1      Status of  Restricted  Performance  Shares.  With  respect  to the
status of the  Restricted  Performance Shares, at the time of execution of this
Agreement Participant understands and agrees to all of the following:

(a) Participant agrees that the Restricted Performance Shares will not be sold
or otherwise disposed of in any manner that would constitute a violation of any
applicable securities laws, whether federal or state.

(b) Participant agrees that (i) the Company may refuse to register the
Restricted Performance Shares on the stock transfer records of the Company if
such proposed transfer would in the opinion of counsel satisfactory to the
Company constitute a violation of any applicable securities law, and (ii) the
Company may give related instructions to its transfer agent, if any, to stop
registration of the Restricted Performance Shares.

6.2 Certificates and Shareholder Rights. Restricted Performance Shares shall not
constitute issued and outstanding shares of Common Shares until issued and
delivered in accordance with this Agreement and the Plan. Prior to the time the
Restricted Performance Shares are issued and delivered, Participant will not
have the right to vote any Restricted Performance Shares, to receive or retain
any dividends or distributions paid or distributed on issued and outstanding
shares of Common Shares or to exercise any other rights, powers and privileges
of a shareholder with respect to any Restricted Performance Shares. In
accordance with the provisions of Article V, the Company shall deliver to
Participant stock certificates issued in Participant's name for the number of
Restricted Performance Shares that have become Vested.

                                      VII.
                                  Miscellaneous

7.1 Service Relationship. For purposes of this Agreement, any question as to
whether and when there has been a termination of Participant's Service, and the
cause of such termination, shall be determined by the Committee, and its
determination will be final.

communications provided for herein will be in writing and will be deemed to have
been duly given when personally delivered or (i) if Participant is outside of
the United States at the time of transmission of such notice, when sent by

United States at the time of transmission of such notice, when mailed by United
States registered or certified mail, return receipt requested, postage prepaid,
addressed to the Company at its principal executive office and to Participant at
the last address filed with the Company or to such other address as either party
may furnish to the other in writing in accordance herewith, except that notices
of changes of address will be effective only upon receipt.

7.3 Restrictions on Transfer of Shares. No Restricted Performance Shares may be
sold, exchanged, transferred (including, without limitation, any transfer to a
nominee or agent of Participant), assigned, pledged, hypothecated, or otherwise
disposed of, including by operation of law, in any manner that violates the
Forfeiture Restrictions and any other provisions of this Agreement, and, until
the date on which such Forfeiture Restrictions lapse, any such attempted
disposition shall be void. The Company shall not be required (i) to transfer on
its books any shares that will have been transferred in violation of this
Agreement or (ii) to treat as owner of such shares, to accord the right to vote
as such owner, or to pay dividends to any transferee to whom such shares will
have been so transferred.

7.4 Withholding of Tax. To the extent that the receipt of Restricted Performance
Shares or the lapse of any Forfeiture Restriction results in compensation income
to Participant for federal or state income tax purposes, Participant shall
deliver to the Company at the time of such event such amount of money or Common
Shares as the Company may require to meet all obligations under applicable tax
laws or regulations, and, if Participant fails to do so, the Company is
authorized to withhold or cause to be withheld from any cash or Common Shares
remuneration then or thereafter payable to Participant any tax required to be
withheld by reason of such resulting compensation income.

7.5 No Employment  Rights  Conferred.  No provision of this Agreement shall
confer any right upon  Participant to continued employment with the Company or
any Subsidiary.

7.6 Limitation of Rights. No provision of this Agreement shall be construed to
give Participant or any other person any interest in any fund or in any
specified asset or assets of the Company or a Subsidiary.

7.7 Binding  Effect.  This  Agreement  shall be binding upon and inure to
the benefit of any successors to the Company and all persons lawfully claiming
under Participant.

7.8 Governing  Law. This  Agreement  shall be governed by, and construed in
accordance  with,  the laws of the state of Texas.

   IN WITNESS WHEREOF, the Company has caused this Agreement to be duly
executed by its officer thereunto duly authorized, and Participant has executed
this Agreement, all effective as of the Date of Grant.
