Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

(e) On March 15, 2012, the Board of Trustees of Beneficial Bank (the “Bank”), the wholly owned subsidiary of Beneficial Mutual Bancorp, Inc. (the “Company”), adopted the Beneficial Bank 2012 Management Incentive Plan (the “2012 MIP”). The 2012 MIP is a short-term incentive compensation plan that provides eligible participants with the opportunity to earn cash incentives upon the satisfaction of Bank/Company and individual/division performance goals within a specific performance period. The performance period for the 2012 MIP commenced on January 1, 2012 and ends December 31, 2012, unless terminated sooner by the Board of Trustees of the Bank (the “Plan Year”).

Eligibility to participate in the 2012 MIP is limited to those senior leaders who are in a position to successfully execute the Company’s strategic plan resulting in increased shareholder value and superior employee and customer satisfaction. Gerard P. Cuddy, Thomas D. Cestare, James E. Gould and Denise Kassekert have been selected to participate in the 2012 MIP.

The 2012 MIP provides each plan participant with an incentive award opportunity based on a percentage of the participant’s base salary as of December 31, 2012.

The 2012 MIP weights the performance measures as follows:

The Bank/Company performance measures focus on earnings per share (“EPS”), efficiency ratio and Tier 1 Capital Levels which are core measures of the Company’s profitability, expense, discipline and efficiency. The Bank/Company performance measures have a defined range of performance (i.e. threshold, target, and stretch goals), and the achievement of Bank/Company performance measures will be determined at the end of the Plan Year based on the Bank/Company achievement relative to the defined performance goals.

The individual/division performance measures for the 2012 MIP are specific to each participant’s business division within the Bank/Company. These performance measures include, but are not limited to, lending and deposit growth.

The amount of a specific incentive award will vary based on the satisfaction of the performance measures and can range from 0% (if threshold performance is not achieved) to 115% of the target award (if all goals reach stretch level of performance). Incentive awards earned under the 2012 MIP will be paid as a cash bonus before the end of the first quarter following the Plan Year and will be considered taxable income (and subject to tax withholding) for the Plan Year in which they are distributed.
