PEAPACK-GLADSTONE FINANCIAL CORPORATION

REPORTS PRELIMINARY APPROVAL TO PARTICIPATE IN THE US DEPARTMENT OF

TREASURY CAPITAL PURCHASE PROGRAM

GLADSTONE, N.J.—(BUSINESS WIRE)—November 20, 2008 – Peapack-Gladstone Financial Corporation (NASDAQ Global Select Market:PGC) reported that it received preliminary approval as of November 17 from the US Department of Treasury (Treasury) to sell $28,685,000 of preferred stock to Treasury in the Capital Purchase Program.  As part of the transaction the Corporation will issue warrants to Treasury to purchase common stock of the Corporation with a market price, based upon the average closing price for the 20 days prior to November 17, equal to 15% of the preferred stock.

Frank A. Kissel, Chairman and CEO, stated, “A strong capital position has always been fundamental to our culture.  At September 30, 2008 the Corporation’s leverage ratio, tier 1 and total risk based capital ratios were 8.76 percent, 12.41 percent and 13.36 percent, respectively.  Each of these ratios exceeded the levels required to be categorized as “well capitalized”.  As we move through the most severe financial and economic crisis of our lifetimes, we feel it prudent to further strengthen our capital position.”

Because the Corporation’s charter does not presently allow for the issuance of preferred stock, the Corporation must obtain shareholder approval to amend the charter to authorize the issuance of preferred stock.  The process of shareholder approval will require the solicitation of proxies followed by a vote at a special shareholder meeting.  The Corporation filed a preliminary proxy with the Securities and Exchange Commission today which will be mailed to shareholders after a standard review by the SEC staff.  Depending on the length of the SEC review, the Corporation expects to hold a special shareholder’s meeting in the last week of December 2008 or the first or second week of January 2009.

The Treasury’s preliminary approval required that we consummate the transaction within 30 days of the approval date.  Because of the periods needed to allow the Securities and Exchange Commission to review and comment on the proxy statement and thereafter to solicit proxies and to hold the shareholders meeting, it will take us longer than 30 days to close the transaction.  Although we believe the Treasury will allow us additional time to close, there can be no assurance that it will.
