Amegy Bank Executive Named to U.S. Banker Magazine's 25 Women to Watch.

HOUSTON -- Amegy Bank of Texas today announced that Debbie Innes has been named to U.S. Banker magazine's 25 Women to Watch list. Innes is the only executive from a Texas-based financial institution to be named among the magazine's Most Powerful Women in Banking issue, which includes its 25 Most Powerful Women in Banking and the 25 Women to Watch.

Innes was selected from a field of more than 5,070 women of executive-level status in banking and financial institutions across the country. The magazine describes its 25 Women to Watch as "individuals whose performance underscores their talent and commitment to excellence." The criteria used for this year's ranking included year-over-year financial performance, three-year financial performance, charitable work, and management style, among many others.

"Since joining our Bank 13 years ago, Debbie has displayed an unwavering commitment to serving our clients and mentoring our staff," said Paul B. Murphy, Jr., CEO. "She is one of our many employees who personifies excellence and we are proud that U.S. Banker magazine has recognized her efforts."

As Executive Vice President of Retail and Treasury Management Services, Innes is responsible for all sales, product management, and customer support for two of the Bank's most significant business lines. She has also played a significant role working with the Bank's Technology and Operations departments to develop several product and technology innovations, including:

--An online payment system that helps taxpayers pay their property tax bills online.

--A product for several healthcare clients that cross-references patients' bills with their explanation-of-benefits statements to make it easier to get payments from insurance companies. At the time of development and implementation, this product was the first of its kind in the nation.

--An electronic tithing system for churches.

--An automated process for energy companies to verify drilling permits and pay property owners. The product posts information on the Internet and allows companies to make pay or no-pay decisions while enhancing Sarbanes-Oxley requirements.

--In addition, she has overseen the development of an average of four new products a year for the past 10 years.

"I am honored to be recognized with this talented and distinguished list of women bankers," said Innes. "I am equally grateful to work for a company that has made so many opportunities available to me and one that makes serving our clients and colleagues so much fun."

Innes is also an advocate for the community. She has served as former Chairwoman of the Board for "I Have a Dream" - Houston (IHAD) and Secretary of the Board and Chair of Volunteer Services. She is an active board member of the Juvenile Diabetes Research Foundation and was recently named to its Chairman's Circle, a distinct group of individuals who have consistently exhibited leadership, spirit, fundraising ability and tenacity in helping JDRF reach its goal of curing diabetes.
