FOR IMMEDIATE RELEASE                                               June 1, 2000


Rancho Santa Fe National Bank Completes  Merger with First Community Bank of the
Desert and First Community Bancorp is Formed

First  Community  Bancorp (FC  Bancorp)  today  announced it has  completed  its
formation  and has combined  Rancho Santa Fe National  Bank  (Rancho) with First
Community Bank of the Desert (First Community) as its wholly-owned subsidiaries.
Shareholders  for both  banks  approved  the  transaction  at  their  respective
Shareholder  Meetings  held on May 31,  2000.  Under  the  terms  of the  merger
agreement,  each  shareholder  of First  Community  received  0.300 shares of FC
Bancorp common stock for each share of First Community common stock. Each Rancho
share is being  exchanged for one share of FC Bancorp common stock.  At the same
time as completion of the merger,  FC Bancorp  became listed on NASDAQ under the
symbol  FCBP,  thus  adding  liquidity  to its  shareholders.  The  merger  used
pooling-of-interests accounting.

The  merger  created  a $318  million  bank  holding  company  operating  in the
exclusive markets of Northern San Diego County and the desert communities of the
Coachella  Valley.  Each bank will operate under its own name with Rancho having
branches  in  Rancho  Santa Fe,  San  Diego's  Golden  Triangle,  Escondido  and
Carlsbad.  First Community has branches in Palm Springs, Indian Wells, Cathedral
City, Yucca Valley, Joshua Tree and Twentynine Palms.

James A.  Boyce,  President  and Chief  Executive  Officer of Rancho,  will also
assume this role at FC Bancorp. William T. Powers, President and Chief Executive
Officer  of First  Community,  will  continue  in this  role  and also  become a
director of FC Bancorp.  John M. Eggemeyer III, Chairman of the Board of Rancho,
became Chairman of the Board of FC Bancorp. Mr. Eggemeyer  commented,  "In spite
of the burden of the merger  process,  both banks  demonstrated  their focus and
potential by posting  outstanding  earnings growth in the first quarter of 2000,
while  simultaneously  working on integration  tasks.  The combination of Rancho
with First  Community  under FC Bancorp is the first step in the  creation  of a
strong  banking  franchise  that will  focus on  serving  the  banking  needs of
entrepreneurs,  businesses  and real estate  clients  located within an expanded
market area."

In  commenting  on the merger,  William T.  Powers,  President  and CEO of First
Community Bank,  said, "We are looking  forward to a strong working  partnership
with  Rancho  Santa Fe  National  Bank.  The  benefits  of  sharing  technology,
administrative  systems,  and  banking  expertise  will  make our  organizations
significantly stronger and more competitive."

James A. Boyce, President of Rancho Santa Fe, in commenting on the merger stated
that, "In the past, we have enjoyed an excellent working  relationship with Bill
Powers and his team at First Community  Bank. The integration of  administrative
support activities can be accomplished  quickly and we fully expect to reach our
overhead reduction and organizational  restructuring goals during the balance of
this year. It is important to note that improved  operating  efficiency is a key
element  of the  merger,  but we clearly  recognize  our  primary  focus must be
service to our customers. Our future is directly related to our ability to serve
their needs responsively and competitively."
