ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On December 6, 2012, Pacific Premier Bancorp, Inc. (the "Company") entered into an underwriting agreement (the "Underwriting Agreement") with Raymond James & Associates, Inc., as underwriter and representative of the other underwriter, D.A. Davidson & Co., to issue and sell 3,300,000 shares of the Company's common stock, par value $0.01 per share ("Common Stock"), at a public offering price of $10.00 per share in an underwritten public offering (the "Offering"). As part of the Offering, the Company granted the underwriters a 30-day option to purchase up to an additional 495,000 shares of Common Stock to cover over-allotments, if any. The underwriting discounts and commissions were $0.55 per share. The net proceeds of the Offering, after underwriting discounts and expenses, and without exercise of the underwriters' over-allotment option, will be approximately $30,880,000.

The Underwriting Agreement contains customary representations, warranties and covenants among the parties as of the date of entering into such Underwriting Agreement. These representations, warranties and covenants are not factual information to investors about the Company. A copy of the Underwriting Agreement is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference.
