1,548,813  shares  of  Common  Stock  were  issued  to  Investors  Savings  Bank
Charitable  Foundation,  and  51,627,094  shares  of Common  Stock  were sold to
depositors and the  tax-qualified  employee stock benefit plans of the Bank (the
"Stock  Offering").  On June 16, 2008,  the Issuer  issued  1,744,592  shares of

value  of  Summit  MHC  that  was  transferred,  on  behalf  of  Summit  Federal
depositors,  to the Company. The number of Issuer shares that were issued to the
Company  equaled  (i) the  Appraised  Valuation  of Summit,  divided by (ii) the
average of the  closing  sales  price of a share of Issuer's  common  stock,  as
reported on Nasdaq stock market,  for the twenty (20)  consecutive  trading days
ending on the second  trading day preceding the date as of which the shares were
issued.
