Item 1.01. Entry into a Material Definitive Agreement.

Employment Agreement

On March 9, 2012, Farmer Bros. Co., a Delaware corporation (the “Company”), and Michael H. Keown entered into an Employment Agreement (the “Keown Employment Agreement”), pursuant to which the Company will employ Mr. Keown as President and Chief Executive Officer. Mr. Keown’s employment is expected to commence on March 23, 2012 (the “Commencement Date”).

The following description of the Keown Employment Agreement does not purport to be complete and is qualified in its entirety by reference to the Keown Employment Agreement, which is filed herewith as Exhibit 10.1 and incorporated herein by reference.

Pursuant to the Keown Employment Agreement, Mr. Keown’s initial annual base salary will be $475,000. Mr. Keown will be entitled to participate in the Farmer Bros. Co. 2005 Incentive Compensation Plan (the “Incentive Plan”), with a Target Award (as defined in the Incentive Plan) equal to one hundred percent (100%) of his base annual salary, prorated for fiscal 2012 based on the Commencement Date. In addition, Mr. Keown is entitled to a guaranteed bonus for fiscal 2012 of $475,000, prorated based on the Commencement Date, and a guaranteed bonus for fiscal 2013 equal to one-third (1/3) of his fiscal 2013 Target Award.

Mr. Keown will be entitled to all benefits and perquisites provided by the Company to its senior executives, including paid days off, group health insurance, life insurance, 401(k) plan, employee stock ownership plan, cell phone, Company credit card, expense reimbursement and an automobile allowance. In addition, the Company will pay and/or reimburse certain expenses related to Mr. Keown’s relocation to Southern California.

In accordance with the provisions of the Farmer Bros. Co. 2007 Omnibus Plan (the “Omnibus Plan”), on the Commencement Date, or on the first business day following the end of any regular blackout period if the Commencement Date is during a regular blackout period, Mr. Keown will be granted the following equity awards: (i) fifteen thousand (15,000) shares of restricted stock to vest in its entirety on the third anniversary of the grant date; (ii) seventy thousand (70,000) nonqualified stock options to vest ratably over three years on each anniversary of the grant date; and (iii) such number of shares of restricted stock equal to $175,000 divided by the closing price of the Company’s common stock on the award date to vest fifty-eight percent (58%) on the first anniversary of the grant date and forty-two percent (42%) on the second anniversary of the grant date, in each case subject to accelerated vesting upon certain events of termination. Mr. Keown will be entitled to participate in such future grants under the Omnibus Plan as are made by the Compensation Committee and the Board of Directors from time to time to senior Company officers. The Form of 2007 Omnibus Plan Stock Option Grant Notice and Stock Option Agreement and the Form of 2007 Omnibus Plan Restricted Stock Award Grant Notice and Restricted Stock Award Agreement and the Stock Ownership Guidelines for Directors and Executive Officers have been filed with the SEC as Exhibits to the Form 8-K filed on February 26, 2008 and are incorporated herein by reference.

Mr. Keown’s employment may be terminated by the Company at any time with or without Cause or upon Mr. Keown’s resignation with or without Good Reason, death or Permanent Incapacity, as such terms are defined in the Keown Employment Agreement. Upon certain events of termination, Mr. Keown is entitled to severance benefits, including base salary continuation, partially Company-paid COBRA coverage, and a prorated Target Award under the Incentive Plan. In addition, if termination occurs after the end of a fiscal year but before the Compensation Committee takes final action on Incentive Plan bonuses for the preceding fiscal year, in certain events Mr. Keown will be entitled to a bonus for the preceding fiscal year. Receipt of any severance amounts is conditioned upon execution of a general release of claims against the Company. If Mr. Keown becomes eligible for severance benefits under the Change in Control Severance Agreement described below under this Item 1.01, the benefits provided under that agreement will be in lieu of, and not in addition to, the severance benefits under the Keown Employment Agreement.
