                               CERTIFICATION FORM

  (THIS CERTIFICATION FORM MUST BE SIGNED IN ADDITION TO THE STOCK ORDER FORM)

     I ACKNOWLEDGE THAT THIS SECURITY IS NOT A DEPOSIT OR ACCOUNT AND IS NOT
     FEDERALLY INSURED, AND IS NOT GUARANTEED BY PUTNAM SAVINGS BANK, PSB
     HOLDINGS, INC., OR BY THE FEDERAL GOVERNEMENT

     If anyone asserts that this security is federally insured or guaranteed, or
     is as safe as an insured deposit, I should call the Office of Thrift
     Supervision Regional Director, Robert C. Albanese, at (201) 413-1000.

     I further certify that, before purchasing the common stock of PSB Holdings,
     Inc, I received a copy of the prospectus dated _______, 2004, which
     discloses the nature of the common stock being offered and describes the
     following risks involved in an investment in the common stock under the
     heading "Risk Factors" beginning on page __ of the prospectus:

 1.  Strong competition within our market area may limit our growth and
     profitability.

 2.  Because we intend to increase our commercial real estate and commercial
     loan originations, our lending risk will increase and downturns in the real
     estate market or local economy could adversely affect our earnings

 3.  The future price of the common stock may be less than the purchase price in
     the offering.

 4.  There will be a limited trading market in our common stock, which will
     hinder your ability to sell our common stock and may lower the market price
     of the stock.

 5.  If economic conditions deteriorate, our results of operations and financial
     condition could be adversely affected as borrowers' ability to repay loans
     declines and the value of the collateral securing our loans decreases.

 6.  If our allowance for loan losses is not sufficient to cover actual loan
     losses, our earnings could decrease.

 7.  Future changes in interest rates may reduce our profits.

 8.  Our return on equity will be low compared to other financial institutions.
     This could negatively affect the trading price of our common stock.

 9.  The issuance of shares to the charitable foundation will dilute your
     ownership interests and adversely affect net income in fiscal 2005.

 10. Our contribution to the Putnam Savings Foundation may not be tax
     deductible, which could reduce profits.

 11. Our stock benefit plans will increase our costs, which will reduce our
     income.

 12. The implementation of stock-based benefit plans may dilute your ownership
     interest.

 13. We have broad discretion in allocating the proceeds of the Offering. Our
     failure to effectively utilize such proceeds could hurt our profits.

 14. Persons who purchase stock in the offering will own a minority of PSB
     Holdings, Inc. common stock and will not be able to exercise voting control
     over most matters put to a vote of stockholders.

 15. We operate in a highly regulated environment an may be adversely affected
     by changes in laws and regulations.

 16. Our stock value may be negatively affected by Federal regulations
     restricting takeovers and our mutual holding company structure.
