    Foothill Independent Bancorp Announces 5-for-4 Stock Split and
      Declares Regular Quarterly Cash Dividend of $0.13 Per Share

    GLENDORA, Calif.--(BUSINESS WIRE)--April 28, 2005--

   Cash Dividend to Be Paid on Shares Outstanding After Stock Split,
            Effectively Increasing the Cash Dividend by 25%

    Foothill Independent Bancorp (NASDAQ:FOOT), the holding company
for Foothill Independent Bank, announced today that its Board of
Directors has approved a 5-for-4 stock split to be implemented by
means of 25% stock dividend and, pursuant to its dividend policy, has
declared the quarterly cash dividend of $0.13 per share, which will be
paid on all of the shares that will be outstanding after the stock
split, which effectively increases the amount of the quarterly cash
dividend that Foothill's shareholders will receive by 25%.
    The Stock Split. As a result of the 5-for-4 stock split,
Foothill's stockholders will receive one additional share of common
stock for every four shares of common stock that they own at the close
of business on the record date established for the stock split, which
is May 10, 2005. The additional shares will be distributed on May 25,
2005; however, in lieu of receiving any fractional shares that will
result from the stock split, stockholders will receive a cash payment
based on the closing price of Foothill's common stock on the record
date, as adjusted for the 5-for-4 stock split.
    The stock split will increase the number of Foothill's outstanding
shares by 25% to approximately 8,446,100. As of April 26,2005 a total
of 6,756,928 shares were outstanding.
    The Cash Dividend. The $0.13 quarterly cash dividend will be
payable on June 10, 2005 to all stockholders of record as of the close
of business on May 26, 2005, one day after the issuance of the
additional shares in the stock split. The Board of Directors chose May
26, 2005 as the record date in order to achieve a 25% increase in the
amount of the quarterly cash dividends that Foothill intends to pay to
stockholders hereafter, commencing with this quarterly cash dividend.
    George Langley, Foothill's President and Chief Executive Officer,
stated, "We continue to focus on measures that we believe will build
value for our stockholders. The combination of the stock split, which
should result in increased share liquidity by increasing the number of
shares in the public float, and the 25% increase in the amount of the
regular quarterly cash dividend that we pay to our stockholders, we
believe, are excellent ways to build wealth and increase value for
Foothill investors."
    "Foothill recently reported that it had achieved record first
quarter earnings, with net income increasing 18% in the quarter ended
March 31, 2005, over the same period last year, to $2.6 million, or
$0.31 per diluted share, which contributed to the Board's decision to
split the stock and increase the cash dividend," added Langley.
