SEVERANCE AGREEMENT

At Will Employment. The Executive shall be and continue as an at will employee of the Company. The Executive shall be entitled to receive such compensation and benefits as the Board of Directors (the “Board”) of Global Brass and Copper Holdings, Inc. (“GBCH”) and management of the Company shall determine appropriate from time to time, subject to the rights that may be created in the Executive under the definition of Good Reason below. This Agreement is not a contract of employment and shall not be interpreted to change the Executive’s status as an employee at will of the Company. The purpose of this Agreement is to provide for payment of severance amounts in the event the Executive’s employment with the Company terminates under the specific terms and conditions set forth herein.

Severance. In the event of the occurrence of any Triggering Event (as hereinafter defined), and subject to the Executive’s execution, delivery and nonrevocation of the general waiver and release of claims substantially in the form attached as Exhibit A hereto within fifty-five (55) calendar days following a Triggering Event (the “Release Condition”), (A) the Company shall provide to the Executive a lump sum severance payment (the “Severance Payment”) in immediately available funds in an amount equal to the sum of (i) one year of base pay at the highest rate of base salary payable to the Executive during the one year period immediately prior to the Triggering Event and (ii) the higher of (x) fifty percent (50%) of the highest rate of base salary payable to the Executive during the one year period immediately prior to the Triggering Event, (y) the target annual bonus amount established for the Executive under any annual bonus plan, such as the Executive Officers 2017

Accrued Payments. In addition to the Severance Payment and benefits provided under Section 1.02 above, the Executive shall be entitled to receive as soon as practicable, and in all events within thirty (30) calendar days following the date of the Triggering Event, (i) payment of any accrued but unpaid base salary and any accrued and unreimbursed business expenses in accordance with Company policy, in each case accrued or incurred through the date of the Triggering Event, (ii) any payments, benefits or entitlements that are vested, fully and unconditionally earned pursuant to any Company or GBCH plan, policy, program or arrangement, or other agreement, other than those providing for severance, separation pay or salary and benefits continuation, (iii) earned but unpaid vacation pay, and (iv) any bonus earned under the Bonus Plan for a completed year prior to the year in which the Triggering Event occurs but unpaid as of the Triggering Event (collectively, the “Accrued Payments”).”

Triggering Event. A Triggering Event shall be deemed to occur if the Company terminates the Executive’s employment with the Company without Cause or the Executive resigns for Good Reason.

Termination by the Company for Cause. For purposes of this Agreement, “Cause” shall mean (i) failure or refusal to perform the Executive’s duties as President of Olin Brass after written notice from the CEO; (ii) willful misconduct or gross negligence in the performance of the Executive’s duties to Company that has an adverse effect on the Company after receipt of at least one warning from the Company; (iii) intentional breach of a written covenant with or written policy of the Company relating to the use and preservation of intellectual property and/or confidentiality; (iv) being impaired by or under the influence of alcohol, illegal drugs or controlled substances while working or while on the property of the Company or Olin Brass or any of their affiliated entities; (v) conviction of or plea of nolo contendere to a felony; or (vi) dishonest, disloyal or illegal conduct or gross misconduct which materially and adversely affects the Executive’s performance or the reputation or business of the Company or Olin Brass or any of their affiliated entities (it being agreed that a petty offense or a violation of the motor vehicle code shall not constitute Cause) provided, however, that prior to the determination that “Cause” under clause (i), (ii), (iii), (iv) or (vi) of this Section 1.05 has occurred, the Board shall (x) provide to the Executive in writing, in reasonable detail, the reasons for the determination that such “Cause” exists, (y) afford the Executive a thirty (30) day opportunity to remedy any such breach, if such breach is capable of being remedied during such 30 day period, and (z) provide the Executive an opportunity to be heard prior to the final decision to terminate the Executive’s employment hereunder for such “Cause”. Notwithstanding the preceding sentence, the Board may terminate the Executive without any advance notification if the “Cause” event is incapable of reasonably prompt cure or if the Board determines that its fiduciary duty requires such termination. The Board shall make any decision that “Cause” exists in good faith. For purposes of this Agreement, no act or failure to act on the Executive’s part shall be considered “willful” unless it is done, or omitted to be done, by the Executive in bad faith or without reasonable belief that her/his action or omission was in the best interests of the Company or any successor or affiliate. Any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the Board or based upon the advice of counsel for the Company, or any successor or affiliate, shall be conclusively presumed to be done, or omitted to be done, in good faith and in the best interests of the Company, or any successor or affiliate thereof.

Resignation by the Executive for Good Reason. For purposes of this Agreement, “Good Reason” shall mean any of the following without the Executive’s prior written consent: (i) assignment of duties materially and adversely inconsistent with the Executive’s position as President of Olin Brass and which results in a material diminution in such position, authority, duties or responsibilities as herein contemplated; or (ii) any material diminution in base salary, bonus opportunity or benefits; provided, however, that in each case the Company or Olin Brass, as applicable, has failed to cure the applicable circumstance within thirty (30) calendar days following written notice from the Executive; and provided, further, that the Executive must provide written notice of events claimed to constitute Good Reason within sixty (60) calendar days of the initial

Resignation from Other Positions on Termination. The Executive acknowledges and agrees that effective as of the date of the Triggering Event, the Executive shall be deemed to have resigned from any and all titles, positions and appointments the Executive holds in the Company, Olin Brass or any of their parents, subsidiaries or affiliates, whether as an officer, director, or employee, consultant, independent contract or otherwise. The Executive agrees to execute such documents as the Company or Olin Brass, in its sole discretion, shall reasonably deem necessary to effect such resignations.

Confidentiality. During the term of this Agreement and during the five year period subsequent to the expiration or termination of this Agreement, the Executive shall maintain in the strictest confidence any and all information regarding the Company, and its affiliated organizations, regarding their methods of operations; contracts and agreements; financial information and financial statements; vendor, customer and marketing information and lists; policies and procedures; personnel, employment practices and conditions; marketing and strategic plans and initiatives; customer and supplier relationships; prices and contracts; price structure; cost structure; and any and all other information obtained directly or indirectly by the Executive deemed by the Company or its affiliated organizations to be confidential (all of the foregoing shall be identified hereinafter as “Confidential Information”).
