     to  paragraphs  (b)(3)  and  (b)(4) of Item 703 with  respect  to the share
     repurchase  tables  contained in the Form 10-K and your Form 10-Q.  Confirm
     that you will revise future filings accordingly.

     The  Company  currently  has one stock  repurchase  program in place.  That
repurchase  program was  announced  on  February  23,  2009 and  authorized  the
repurchase of up to 841,138 shares of common stock.  There is no expiration date
for this program.


     The Company also had a previously authorized stock repurchase program. That
repurchase  program was  announced  on  November  20,  2008 and  authorized  the
repurchase of 885,879 shares.  That repurchase program was completed in February
2009.

     There were no repurchase  programs that expired or were terminated prior to

     As  requested  by the Staff,  the  Company  will revise  future  filings to
include by footnote the forgoing information.

3.   We note your  disclosure  that  transactions  with  affiliates were made on
     substantially the same terms,  including interest rates and collateral,  as
     those prevailing for comparable loans to other persons. Please confirm that
     the loans were made on  substantially  the same terms,  including  interest
     rates and collateral,  as those prevailing at the time for comparable loans
     with persons not related to the lender. Confirm that you will revise future
     filings accordingly. Refer to Instruction 4(c) to Item 404(a) of Regulation
     S-K.

     We confirm that loans by United Bank, the Company's bank  subsidiary,  were
made on substantially the same terms,  including  interest rates and collateral,
as those prevailing at the time for comparable loans with persons not related to
United Bank. As requested by the Staff,  the Company will revise future  filings
accordingly.


Exhibit 3.2
- -----------

4.   Your Amended and Restated  Bylaws  included as Exhibit 3.2 to the Form 10-K
     indicate that they were amended on September 18, 2008. You do not appear to
     have filed a Form 8-K reporting any amendment(s) at that time.  Please tell
     us the nature of the  September  18, 2008  amendment(s)  and  explain  your
     conclusion that a Form 8-K filing was not required.

     As noted in the  comment,  the  Bylaws  of the  Company  were  amended  and
     restated  on  September  18, 2008 to adjust from June to April the month in
     which the Company's annual meeting is convened.  No other changes were made
     to the Bylaws. The Company acknowledges that the Bylaw amendment called for
     a  filing  of a Form  8-K;  the  Company's  failure  to file a Form 8-K was
     inadvertent.  The  complete  Amended and Restated  Bylaws were  included as
     Exhibit  3.2 to the Form  10-K  once the  failure  to file the Form 8-K was
     discovered.

Exhibits 31.1 and 31.2
- ----------------------

5.   We note that your certifications  included as Exhibits 31.1 and 31.2 to the
     Form  10-K and the Form 10-Q  contain  modifications  of the exact  form of
     certification  as set  forth  in Item  601(b)(31)  of  Regulation  S-K.  In
     particular, the language "(or persons performing the equivalent functions)"
     has been deleted from  paragraph 5. In future  filings,  please ensure that
     the certifications are in the exact form as set forth in Item 601(b)(31) of
     Regulation S-K, except as otherwise  indicated in Commission  statements or
     staff interpretations.

     The  Staff's  comment  is noted.  We  confirm  that in future  filings  the
     certifications  will be  reproduced  in the exact form as set forth in Item
     601(b)(31) of Regulation S-K.
