Section 8 - Other Events
Item 8.01 Other Events

Following  the action taken by the United  States  Treasury  Department  and the
Federal  Housing  Finance  Agency  to  place  the  Federal   National   Mortgage
Association  ("FNMA") in  conservatorship,  Cornerstone  Bancorp (the "Company")
will  evaluate the FNMA  preferred  stock held by its wholly  owned  subsidiary,
Cornerstone  National Bank, for impairment as of the end of the third quarter of
2008.  The Bank holds  40,000  shares of FNMA  Series S  preferred  stock with a
carrying  value as of June 30, 2008, of  $951,240.00.  As a result of the action
taken to place FNMA in conservatorship, dividends for these securities have been
suspended and the market value of these securities has decreased  substantially.
The Company  will report the effects of the  decrease in value in its  quarterly
report for the quarter ended September 30, 2008.

Management  has evaluated the capital  position of the Company and the Bank, and
believes both will continue to have capital levels above the "Well  Capitalized"
threshold as promulgated  by federal  banking  regulators,  after any impairment
charges.
