OF

PACIFIC PREMIER BANCORP, INC.

Pursuant to resolutions adopted by the Board of Directors of Pacific Premier Bancorp, Inc. (the “Corporation”) on September 29, 2010, the Bylaws, as amended, of the Corporation are hereby amended as follows:

1.           Article I, Section 6 shall be amended and restated in its entirety as follows:

(a)           Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, the chairman of the meeting shall have the power to determine whether a nomination or any other business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with each of the procedures set forth in Sections 6(b), 6(d) and 6(e) of this Article I and, if any proposed nomination or other business is not in compliance with each of Sections 6(b), 6(d) and 6(e) of this Article I, to declare that such defective proposal or nomination shall be disregarded.  To be properly brought before a meeting of stockholders, business must be of a proper subject for action by stockholders under applicable law and must not, if implemented, cause the Corporation to violate any state, federal or foreign law or regulation, each as determined in good faith by the Board of Directors.

 (b)           At any annual meeting of the stockholders, only such nominations of persons for election to the Board of Directors shall be made, and only such other business shall be conducted or considered, as shall have been properly brought before the meeting.  For nominations to be properly made at an annual meeting, and proposals of other business to be properly brought before an annual meeting, nominations and proposals of other business must be  (1) specified in the Corporation’s notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors, (2) otherwise properly made at the annual meeting, by or at the direction of the Board of Directors or (3) otherwise properly requested to be brought before the annual meeting by a stockholder of the Corporation in accordance with these Bylaws.  For nominations of persons for election to the Board of Directors or proposals of other business to be properly requested by a stockholder to be made at an annual meeting, a stockholder must (i) be a stockholder of record at the time of giving of notice of such annual meeting by or at the direction of the Board of Directors and at the time of the annual meeting, (ii) be entitled to vote at such annual meeting and (iii) comply with the additional requirements and procedures set forth in Sections 6(d) and 6(e) of this Article I as to such nomination or other business.  The immediately preceding sentence shall be the exclusive means for a stockholder to make nominations or submit other business (other than matters properly brought under Rule 14a-8 or Rule 14a-11 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and included in the Corporation’s notice of meeting) before an annual meeting of stockholders.

(c)           Subject to Section 6(e)(4) of this Article I, at any special meeting of the stockholders, only such business shall be conducted as shall have been brought before the meeting by or at the direction of the Board of Directors.

(d)           Without qualification or limitation, subject to Section 6(e)(4) of this Article I, for any nominations or any other business to be properly brought before an annual meeting by a stockholder pursuant to Section 6(b) of this Article I, the stockholder must have given timely notice thereof and timely updates and supplements thereof in writing to the Secretary.

To be timely, a stockholder’s notice shall be delivered to the Secretary at the principal executive offices of the Corporation not earlier than the close of business on the 120th day and not later than the close of business on the 90th day prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than the close of business on the 120th day prior to the date of such annual meeting and not later than the close of business on the later of the 90th day prior to the date of such annual meeting or, if the first public announcement of the date of such annual meeting is less than 100 days prior to the date of such annual meeting, the 10th day following the day on which public announcement of the date of such meeting is first made by the Corporation.  In no event shall any adjournment or postponement of an annual meeting, or the public announcement thereof, commence a new time period for the giving of a stockholder’s notice as described above.

Notwithstanding anything in the immediately preceding paragraph to the contrary, in the event that the number of directors to be elected to the Board of Directors is increased by the Board of Directors, and there is no public announcement by the Corporation naming all of the nominees for director or specifying the size of the increased Board of Directors at least 100 days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice required by this Section 6(d) shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the 10th day following the day on which such public announcement is first made by the Corporation.

In addition, to be timely, a stockholder’s notice shall be updated and supplemented, if necessary, so that the information provided or required to be provided in such notice shall be true and correct as of the record date for the meeting and as of the date that is ten (10) business days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to the Secretary at the principal executive offices of the Corporation not later than five (5) business days after the record date for the meeting in the case of the update and supplement required to be made as of the record date, and not later than eight (8) business days prior to the date for the meeting, any adjournment or postponement thereof in the case of the update and supplement required to be made as of ten (10) business days prior to the meeting or any adjournment or postponement thereof.

(e)(1)           Without qualification or limitation, for a stockholder’s notice required to be given to the Secretary pursuant to this Article I to be considered to be in proper form, such stockholder’s notice must include the following, as applicable.
