Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers; Compensatory Arrangements of Certain Officers.

On June 15, 2011, Mr. Jerry W. Burris, a named executive officer of Barnes Group Inc. (the “Company”), and the Company entered into a transition and separation agreement (the “Agreement”) regarding (1) Mr. Burris’ provision of transition services between May 20, 2011, when the Company announced an organizational restructuring, and August 20, 2011, when Mr. Burris will cease to be employed by the Company and (2) Mr. Burris’ separation from the Company.

Under the Agreement, in addition to agreeing to provide transition services, Mr. Burris signed a release of claims and made customary commitments regarding confidentiality, non-solicitation, non-disparagement and cooperation with the Company. Mr. Burris will continue as an employee of the Company during the period in which he will provide transition services and will be paid his salary at the same rate and entitled to the same benefits, including executive level benefits, as before May 20, 2011. Thereafter, Mr. Burris is entitled to benefits under the Company’s Executive Separation Pay Plan (as amended effective January 1, 2011 which was filed with the Securities and Exchange Commission as an attachment to the Company’s 10-Q, for the quarter ended September 30, 2010, on October 29, 2010).

The Agreement also provides that if Mr. Burris signs an additional release on or after August 20, 2011 and prior to September 11, 2011, and complies with all terms of the Agreement, then, in addition to the benefits under the Company’s Executive Separation Pay Plan, the Company will make to Mr. Burris a one-time cash payment of $100,000 on September 20, 2012 and arrange to provide executive-level outplacement services of up to $15,000 with a mutually acceptable outplacement service firm for up to six months.
