Dear Fellow Shareholder: May 8, 2007

I am writing to you with some important news about Center Bancorp. Earlier this week, your Board of Directors announced that it had retained Keefe, Bruyette and Woods as its financial advisor to assist the Company in reviewing strategic alternatives. We anticipate reviewing a wide range of options, including a possible sale of the Company, but there can be no assurance of any particular outcome. We also intend to continue the implementation of our strategic plan, which we believe has improved the value and long-term prospects of your Company.

I want you to know that this is not a decision your Board takes lightly. We have a deep commitment to, and demonstrated track record of, taking action to create value for shareholders. We therefore decided to pursue this course to look at the best ways to maximize shareholder value for all our shareholders going forward.

Our Annual Meeting of Shareholders is just days away. I urge you to protect the long-term value of your investment and vote the BLUE proxy card TODAY for Center Bancorp’s Director nominees - Brenda Curtis, John J. Davis, Donald G. Kein and Norman F. Schroeder.

We believe that our board and management are the right team to conduct this strategic review. Your Board and Management are committed to conducting a careful and thorough process. Despite his protestations to the contrary, based on dissident investor Larry Seidman's track record of selling banks, we do not believe that the intentions of his Committee to Preserve Shareholder Value are in the best interests of all Center Bancorp shareholders.

We also believe the review of strategic alternatives will be best accomplished without the disruption of Mr. Seidman and other dissident directors on our board. I want to remind you that in 1995, the Office of Thrift Supervision issued a Cease and Desist Order and levied a Civil Money Penalty against Mr. Seidman, after finding that he recklessly engaged in unsafe and unsound practices in the business of an insured banking institution.

Let me be very clear about a critical point - your Board and Management have a demonstrated record of, creating long-term value for Center Bancorp shareholders. We pledge to make decisions about Center Bancorp in the best long-term interests of all of our shareholders, not just a small group interested in short-term gains.

Please vote the BLUE proxy card FOR the reelection of Directors Curtis, Davis, Kein and Schroeder TODAY. If you have received or submitted a WHITE proxy card please disregard that card and note that only your most recent vote counts. There is still time for shareholders who wish to change their vote to do so by contacting our proxy solicitor, Georgeson, Inc. at 1-888-897-6050.

Sincerely,

John J. Davis,

President and Chief Executive Officer
