Vesting Period / Performance Period	From the Grant Date through the Vesting Date

Please note that the vesting of the RSUs and PSUs and the delivery of Shares (or a cash equivalent in respect of such RSUs and PSUs) is subject to the satisfaction of the Continued Service Condition. The vesting of the PSUs is, in addition, subject to the satisfaction of the Performance Condition. The level of achievement of the Performance Condition shall be determined by comparing the Constellium TSR to the average of the TSRs of the two Indices at the end of the relevant Performance Period as follows:

Performance Condition Achievement Level	Number of Shares underlying PSUs
The Constellium TSR is below the average of the two median TSRs	PSU Base Amount x 0%
The Constellium TSR is at the average of the two median TSRs	PSU Base Amount x 100%
The Constellium TSR is between the average of the two median TSRs and the average of the two 75th percentile TSRs	PSU Base Amount x (linear interpolation between 100% and 200%)
The Constellium TSR is at or above the average of the two 75th percentile TSRs	PSU Base Amount x 200%

Notwithstanding the foregoing, if the Constellium TSR is negative, the number of Shares (or a cash equivalent) eligible to be delivered in respect of the PSUs shall be capped at 100% of the Base Amount.

You acknowledge that you have received a copy of, or have online access to, the Award Agreement and the Plan, and hereby accept the Units granted, subject to all the terms and provisions of this Award Letter, the Award Agreement and the Plan. The Board or the Committee shall determine whether an event has occurred resulting in the forfeiture of your Units and any Shares issuable thereunder and all such determinations shall be final and conclusive. You also acknowledge that this award and similar awards are made on a selective basis and are, therefore, to be kept confidential.

Very truly yours	Agreed and Accepted
