|(1) | IBCs stand alone earnings before income taxes includes dividends received from Intervest National Bank, its wholly-owned subsidiary, for
purposes of this calculation as follows: none in 2010, $3,933,000 in 2009 and $3,507,000. In 2010, INB was required by its primary regulator to suspend its dividend payments to IBC. See the section Supervision and Regulation in
Item 1 Business of IBCs annual report on Form 10-K for the year ended December 31, 2010 for further discussion of this restriction imposed on INB.

|(2) | Fixed charges for purposes of this calculation represent the aggregate of interest expense on debentures and other short-term borrowings,
amortization of debenture offering costs and preferred stock dividend requirements, which are comprised of preferred stock dividends and related preferred stock discount amortization.
