            CENTER BANCORP, INC. COSUMMATES MERGER WITH RED OAK BANK

Union, New Jersey, May 20, 2005 ---Center Bancorp Inc. (NASDAQ, NM: CNBC) parent
company to Union Center National Bank of Union, New Jersey, completed its
previously announced merger with Red Oak Bank effective at the close of business
today. Red Oak Bank, headquartered in Morristown, New Jersey, was a state
chartered commercial bank with approximately $98 million in assets.

Under the merger agreement, half of the outstanding Red Oak shares will be

converted into a total of approximately one million shares of Center Bancorp
common stock. Center anticipates that the transaction will be accretive to
earnings in 2005.

"The merger with Red Oak was consistent with our company's continued strategy of
highly focused growth within approximately 50 miles of our headquarters, through
new branches and acquisitions of other financial institutions with a similar
customer culture. In our view, Red Oak represented Center's best possible
acquisition candidate currently in Morris County. This was an opportunity for
Center to expand its franchise and provide its full complement of services along
with its high level of customer service to this market. Red Oak offered Center
the opportunity to take advantage of the growing market place in Morris County
and to further our commitment to that area" said John J. Davis, President & CEO.

Bank, Union, New Jersey, currently operates thirteen banking locations. Banking
