          “The confidence shown in Texas Capital with the commitment of new capital by these institutional investors is extremely gratifying,” said George Jones, president and CEO of Texas Capital. “Capital raised in this extremely well-handled transaction will put Texas Capital in a strong position to pursue growth opportunities in Texas. Texas Capital remains well positioned with a proven business strategy. Economic conditions in major markets of Texas have remained relatively strong, and the Company sees a significant opportunity to increase market share.” He also noted that the Company is very pleased that the investor group includes both current shareholders and those new to Texas Capital.
