Ladies and Gentlemen:


Reference is hereby made to that certain Stock Purchase Agreement,
dated as of February 2, 2007 (the “Purchase Agreement”),
by and among the Purchaser, the Sellers and the Shareholders.  The capitalized terms not defined herein
shall have the meanings assigned to them in the Purchase Agreement.  This letter agreement (this “Agreement”) confirms the agreement and understanding between
the parties hereto to amend the Purchase Agreement as follows:


1.             The
Closing.  The first sentence
of  Section 2.6 of the
Purchase Agreement is hereby amended and restated in its entirety as follows:


“Unless this
Agreement shall have been terminated and the transactions herein contemplated
shall have been abandoned pursuant to Article 8 and subject to the satisfaction
or waiver of the conditions set forth in Article 7, the closing of
the transactions contemplated herein (the “Closing”)
shall take place at 10:00 a.m. on March 2, 2007 or on such other date mutually
agreed by the parties (the “Closing Date”)
at the offices of Haynes and Boone, LLP, legal counsel to the Purchaser,
located at 1221 McKinney Street, Suite 2100, Houston, Texas 77010, unless
another date, time or place is agreed to in writing by the parties hereto.”


2.             Termination
Events.  Section 8.1(e) of the Purchase
Agreement is hereby amended and restated in its entirety as follows:


“by either the
Purchaser or the Sellers and the Shareholders if the Closing has not occurred
(other than through the failure of any party seeking to terminate this Agreement
to comply fully with its obligations under this Agreement) on or before March
9, 2007, or such later date as the parties may agree upon.”


3.             Miscellaneous.  Except as specifically amended by the terms of this Agreement, the
terms and conditions of the Purchase Agreement shall remain in full force and
effect for all purposes, and the parties hereby ratify and confirm the terms
and conditions of the Purchase Agreement, as amended pursuant to this
Agreement.  This Agreement shall be
binding and inure to the benefit of the parties and their permitted
assigns.  This Agreement constitutes the
entire agreement between the parties hereto with respect to the subject matter
hereof.  It supersedes all prior
negotiations, letters and understandings relating to the subject matter
hereof.  This Agreement shall be
interpreted, construed and enforced in accordance with the laws of the State of
Texas, without regard to principals of conflicts of law.  The
