<p style="margin:0pt 0pt 12.0pt;text-indent:72.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">(1)
To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement to include any material
information with respect to the plan of distribution not previously disclosed

Registration Statement.</font></p>

<p style="margin:0pt 0pt 12.0pt;text-indent:72.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">(2)
That, for the purpose of determining any liability under the Securities Act,
each such post-effective amendment shall be deemed to be a new Registration

securities at that time shall be deemed to be the initial bona fide offering
thereof.</font></p>

<p style="margin:0pt 0pt 12.0pt;text-indent:72.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">(3)

<p style="margin:0pt 0pt 12.0pt;text-indent:36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">(b)
The undersigned Registrant hereby undertakes that, for the purposes of
determining any liability under the Securities Act, each filing of the
Registrant&#146;s annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan&#146;s
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new Registration Statement relating to the securities offered therein, and the

<p style="margin:0pt 0pt 12.0pt;text-indent:36.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">(c)
Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers, and controlling persons of the Registrant
pursuant to the provisions described in Item 6 or otherwise, the Registrant has
been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.&#160; In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer, or controlling person being
registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the&#160;
Securities Act and will be governed by the final adjudication of such
issue.</font></p>

(1)  Issuable upon exercise of options and the
issuance of restricted stock not yet granted under Registrant's 2006 Stock
Awards Plan (the "Plan").  Pursuant to
Rule 416 of the Securities Act of 1933, as amended (the "Securities Act"), this
Registration Statement also covers such indeterminable number of additional
shares as may become deliverable due to future adjustments under terms of the
Plan.
(2)  Estimated in accordance with Rule 457(h) of
the Securities Act solely for the purpose of calculating the registration
fee.  The estimates of the proposed
maximum offering price per share and the proposed maximum aggregate offering
price are based on the average of the high and low prices of the Common Stock
as reported on the American Stock Exchange on April 17, 2007, given that the
price, at which options to be granted in the future may be exercised, is not
currently determinable.
This Registration Statement shall be deemed to
cover securities resulting from stock splits, stock dividends, or similar
transactions as provided in Rule 416(c) of the Securities Act.  Pursuant thereto, this Registration Statement
also covers an indeterminate amount of interests to be offered or sold pursuant
to the stock awards plan described herein.

which indicates that all of the securities offered have been sold or which
deregisters all securities then remaining unsold shall be deemed to be
incorporated by reference in and a part of this Registration Statement from the
date of filing of such documents.
Any
statement contained in a document incorporated, or deemed to be incorporated,
by reference herein shall be deemed to be modified or superseded for purposes
of this Registration
2
Statement to the
extent that a statement contained in a subsequently filed document that also is
or is deemed to be incorporated by reference herein modifies or supersedes such

Item
6.     Indemnification of Directors and Officers.
The
Company's Restated Articles of Incorporation and Bylaws, and Indemnification
Agreements between the Company and certain of its directors and officers,
provide that the Company shall indemnify all directors and officers of the
Company to the full extent permitted by the Texas Business Corporation
Act.  Under such provisions any director
or officer who, in his capacity as such, is made or threatened to be made, a
party to any suit or proceeding, shall be indemnified if such director or
officer acted in good faith and in a manner he reasonably believed to be in, or
not opposed to, the best interests of the Company.  The Restated Articles of Incorporation,
Bylaws, such Indemnification Agreements, and the Texas Business Corporation Act
further provide that such indemnification is not exclusive of any other rights
to which such individuals may be entitled under the Restated Articles of
Incorporation, Bylaws, such Indemnification Agreements, or any Agreement, vote
of stockholders or disinterested directors, or otherwise.

Item 9.     Undertakings.
(a)
The Registrant hereby
undertakes:
(1)
To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement to include any material
information with respect to the plan of distribution not previously disclosed
in the Registration Statement or any material change to such information in the
Registration Statement.
(2)
That, for the purpose of determining any liability under the Securities Act,
each such post-effective amendment shall be deemed to be a new Registration
Statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
(3)
To remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the
offering.
(b)
The undersigned Registrant hereby undertakes that, for the purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
(c)
Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers, and controlling persons of the Registrant
pursuant to the provisions described in Item 6 or otherwise, the Registrant has
been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.  In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer, or controlling person being
registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the 
Securities Act and will be governed by the final adjudication of such
issue.
