     WHEREAS, Section 3.18(c) of the Contribution Agreement restricts the amount

Restriction to permit Western in limited circumstances to purchase Voting
Securities representing a greater percentage of the Voting Securities issued and
outstanding at the time of purchase; and

     WHEREAS, pursuant to Section 6.2 of the Contribution Agreement, Protection

Directors; and

     WHEREAS, Mr. Ben M. Enis and Mr. James Q. Wilson constitute all of the
Continuing Directors and desire to authorize the parties to amend the
Contribution Agreement as contemplated herein;

     NOW, THEREFORE, in consideration of the premises and of the mutual
agreements herein contained, the parties hereto agree as follows:

     Section 1. AMENDMENT TO THE CONTRIBUTION AGREEMENT. Section 3.18(c) of the
Contribution Agreement is hereby amended by deleting such section in its
entirety and substituting the following section in its place:

     Closing Date, Western may in any manner acquire Voting Securities
     representing in the aggregate up to but not exceeding 85% of the Voting
     Securities issued and outstanding at such

     time, provided that Western may acquire Voting Securities representing 85%
     or more of the Voting Securities issued and outstanding at such time to
     the extent that the percentage of Voting Securities beneficially owned by
     Western on a fully diluted basis represents in the aggregate up to but not
     exceeding 81% of the Voting Securities issued and outstanding at such time.

     Section 2. REPRESENTATIONS AND WARRANTIES. Each party hereto hereby
represents and warrants that (i) it has the power and authority and the legal
right to make, deliver and perform this Amendment, (ii) it has taken all
necessary actions to authorize the execution, delivery and performance of this

     Section 3. CONTINUING EFFECT. Except as expressly waived or otherwise
agreed hereby, the Contribution Agreement shall continue to be and shall remain
in full force and effect in accordance with its terms. This Amendment shall be
limited precisely as drafted and shall not constitute a waiver or amendment of
any other term, condition or provision of the Contribution Agreement.

     Section 4. GOVERNING LAW. This Amendment shall be governed by, and
construed and interpreted in accordance with, the laws of the State of Delaware
(without regard to principles of conflict laws).

     Section 5. COUNTERPARTS. This Amendment may be executed by the parties
hereto on any number of separate counterparts, and all of said counterparts
taken together shall be deemed to constitute one and the same instrument.
