     of, or  prohibiting  or mandating  activities  subject to, federal or state
     securities laws or a finding of any violation with respect to such laws.

(f)  All of the Insiders are U.S. citizens.

Item 3.       Source and Amount of Funds or Other Consideration
---------------------------------------------------------------

     The Issuer was formed in April 2004 for the purpose of  becoming  the stock
holding  company of United Bank (the "Bank") and the Company was formed in April
2004 for the  purpose of  becoming  the  mutual  holding  company  parent of the
Issuer.  On July 12,  2005 and  pursuant  to the  Plan of  Stock  Issuance  (the
"Plan"),  9,189,722  shares of Common  Stock  were  issued to the  Company,  and
7,672,153  shares of Common  Stock  were  issued to  depositors  of the Bank and
others (the "Stock Offering").

Item 4.       Purpose of Transaction
------------------------------------

     The primary  purpose of the Issuer's Stock Offering was to allow the Issuer
and the Bank to grow through expanded  operations,  as well as through increased
branching and acquisitions.  In addition,  the Stock Offering gives the Bank and
the Issuer  greater  flexibility  to  structure  and  finance the  expansion  of
operations, including the potential acquisition of other financial institutions,
and to diversify into other financial services. Because the Issuer only issued a
minority of its common stock for sale in the Stock  Offering,  the Bank's mutual
form of ownership and its ability to remain an  independent  savings bank and to
provide community-oriented financial services is expected to be preserved.

     However,  while the  Company  intends to  exercise  its rights as  majority
stockholder,  neither the Company nor the Insiders  currently  have any plans or
proposals  which relate to or would result in: (a) the acquisition by any person
of additional  securities of the Issuer or the  disposition of securities of the
Issuer;  (b)  an  extraordinary   corporate  transaction,   such  as  a  merger,
reorganization or liquidation,  involving the Issuer or any of its subsidiaries;
(c) a sale or  transfer  of a material  amount of assets of the Issuer or any of
its subsidiaries; (d) any change in the present Board of Directors or management
of the Issuer,  including any plans or proposals to change the number or term of
directors  or to fill any  existing  vacancies  on the board;  (e) any  material
change in the present  capitalization or dividend policy of the Issuer;  (f) any
other  material  change in the  Issuer's  business or corporate  structure;  (g)
changes in the Issuer's charter or bylaws or instruments  corresponding  thereto
or other  actions which may impede the  acquisition  of control of the Issuer by
any person; (h) causing a class of securities of the Issuer to be deleted from a
national  securities  exchange  or to cease to be  authorized  or  quoted  in an
inter-dealer  quotation system of a registered national securities  association;
(i) a class of equity securities of the Issuer becoming eligible for termination
of  registration  pursuant to Section  12(g)(4) of the Exchange  Act; or (j) any
action similar to any of those enumerated above.

     In the future,  the Company  and/or the Insiders may  determine to purchase
additional  shares of the  Issuer's  common  stock (or other  securities  of the
Issuer) or the Company  and/or the Insiders may  determine to sell shares of the
Issuer's  Common  Stock.  Any such  determination  will  depend  on a number  of
factors,  including  market  prices,  the  Issuer's  prospects  and  alternative
investments.

Issuer,  including  but not  limited to  transfer or voting of any of the Common
Stock,  finder's fees,  joint  ventures,  loan or option  arrangements,  puts or
calls,  guarantees  of  profits,  division  of  profits  or loss,  the giving or
withholding of proxies,  or otherwise subject to a contingency the occurrence of
which  would give  another  person  voting or  investment  power over the Common
Stock.

Item 7.       Material to be Filed as Exhibits
----------------------------------------------

     None.
