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

On May 8, 2014, Global Brass and Copper Holdings, Inc. (the “Company”) entered into an Employment Agreement (the “Agreement”), with John J. Wasz, the Company’s President and Chief Executive Officer. The Agreement is for an initial term of three (3) years, and on May 8 of each year, the term shall extend for an additional one (1) year period, unless prior written notice is given. If a change in control (as defined in the Company’s 2013 Omnibus Equity Incentive Plan) occurs during the term of the Agreement, the term automatically will be extended until the later of (i) the second anniversary of the change in control, or (ii) the scheduled expiration of the then-current term. The Agreement provides that Mr. Wasz will receive an initial base salary of $725,000 per annum and shall be eligible for an annual incentive bonus plan with a target of 100% of base salary. Mr. Wasz also will be eligible to receive equity awards under the Company’s 2013 Omnibus Equity Incentive Plan and to participate in all other plans and benefits made available by the Company, including reimbursement of expenses for relocation to the Chicago, Illinois metropolitan area under the Company’s relocation policy. The Company shall maintain one or more directors’ and officers’ liability insurance policies covering Mr. Wasz on the same basis as in effect for other senior executive officers.

If the Company terminates Mr. Wasz without cause (as defined in the Agreement), he terminates his employment with Good Reason (as defined in the Agreement), or he terminates his employment within 30 days of receiving notice from the Company that it is not renewing the term of his Agreement, the Company will pay Mr. Wasz or provide the following severance: (i) 24 months continuation of base salary, (ii) the target annual bonus amount established for him for the year preceding his termination, and (iii) continued coverage under the Company’s health plan, dental plan, and life insurance plan for up to one year.

Restrictive covenants, including confidentiality, non-solicit, and non-compete, will apply to Mr. Wasz for 24 months after his employment terminates for any reason. Payments under Mr. Wasz’s Agreement will be subject to any Compensation Recovery Policy established by the Company.

The above description of the Agreement is not complete and is qualified in its entirety by reference to full text of the Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
