California Bank & Trust Supports Affordable Housing Initiatives Through Investments & Donations

SAN DIEGO--(Business Wire)--
California Bank & Trust (CB&T), www.calbanktrust.com, is pleased to announce
that during the first half of the year through investments and contributions
totaling more then $3.6 million, the bank supported affordable housing
initiatives in the state of California. Investments and contributions were made
to various nonprofit and private agencies whose mission is to enhance affordable
housing opportunities throughout California.

CB&T supported the development of more than 1000 units of affordable housing
throughout the state of California through investments and contributions. "One
of the principles that we adhere to at California Bank & Trust is supporting our
communities. Given the economic difficulties many families are facing as it
relates to housing, we found it particularly important to support affordable
housing initiatives and have focused much of our charitable giving on this
cause," said Steve Herman, vice president and community reinvestment manager for
California Bank & Trust.

In Los Angeles, an investment in a fund sponsored by the National Affordable
Housing Trust helped finance the renovation of affordable housing units owned by
the Retirement Housing Foundation of Long Beach. Founded in 1961, the Retirement
Housing Foundation (RHF) is one of the nation's largest nonprofit providers of
housing and services for older adults, persons with disabilities and
economically disadvantaged families.

Additionally, CB&T invested in the Rural Community Assistance Corporation (RCAC)
loan fund. RCAC, a nonprofit organization headquartered in West Sacramento,
provides technical and financial resources and training so that rural
communities can achieve their goals and visions. RCAC finances development of
affordable housing and community facilities; and water and wastewater systems in
rural communities in 13 Western states. CB&T`s investment will be used
exclusively in California.

The Neighborhood Housing Services (NHS) and Community Housing Works will use
CB&T contributions to support home ownership preservation programs. These
programs promote foreclosure prevention through educational workshops, in-person
counseling and community outreach. This three-pronged approach ensures that the
NHS organizations are able to reach out to as many distressed borrowers as
possible while providing individual, customized counseling.

"The donation California Bank & Trust made to Los Angeles Neighborhood Housing
Services allows us to help many home owners who have been affected by the
economy and are consequently in danger of foreclosure," said Lori Gay, president
and CEO of LA NHS. "The generosity of businesses giving to LA NHS enables us to
pursue our mission of building strong neighborhoods and improving the quality of
life for families of modest means."

These are some of the affordable housing organizations CB&T Supported during the
first half of 2009:

* Retirement Housing Foundation in Long Beach
* Local Initiative Support Corporation (LISC) San Diego
* Local Initiative Support Corporation (LISC) Los Angeles
* Neighborhood Housing Services Los Angeles
* Neighborhood Housing Services Orange County
* Community Housing Works San Diego
* Habitat for Humanity
