2017 Long Term Incentive Award Agreement

Award Letter

[DATE]

Dear [Name],

I am pleased to inform you that you have received a Grant of Units under the Constellium 2017 Long Term Incentive Award Agreement in the amounts set forth below.

The 2017 Grants

These Units entitle you to receive Constellium Shares, or a cash equivalent at Constellium’s discretion, subject to the terms and conditions set forth in this Award Letter, in the Constellium 2017 Long Term Incentive Award Agreement (the “Award Agreement”) and the 2013 Constellium Equity Incentive Plan (the “Plan”). Capitalized Terms used in this Award Letter, unless so defined herein, shall have the meanings found in the Award Agreement or Plan.

Grant Date	July 31, 2017
Total number of Units granted	X,XXX
Number of Restricted Stock Units (RSUs) granted	X,XXX
Number of Performance Share Units (PSUs) granted (Base Amount)	X,XXX
Indices	S&P 400 Materials Index and S&P 600 Materials Index
Initial price of a Constellium Share on the Grant Date	$7.83 (20-day average)
Vesting Date	July 31, 2020
Vesting Period	From the Grant Date through and including the Vesting Date
Performance Period	From the Grant Date through and including the Vesting Date

Please note that the vesting of the RSUs and the delivery of Shares in respect of such RSUs are subject to the satisfaction of the Continued Service Condition described in the Award Agreement. The vesting of the PSUs and the delivery of Shares in respect of such PSUs are also subject to the satisfaction of the Continued Service Condition, as well as to the level of achievement of the Performance Condition. This level of achievement shall be determined by comparing the Constellium TSR to the average of the median TSRs of the two Indices on the last day of the relevant Performance Period as follows:

Level of achievement of the Performance Condition	Number of Shares eligible to be delivered
The Constellium TSR is below the average of the two median TSRs	No PSUs will vest and no Shares will be delivered
The Constellium TSR is at the average of the two median TSRs	100% of the PSU Base Amount
The Constellium TSR is at or above the average of the two 75th percentile TSRs	200% of the PSU Base Amount

If the Constellium TSR is between the average of the two median TSRs and the average of the two 75th percentile TSRs, then the number of Shares eligible to be delivered in respect of the PSUs shall be determined by linear interpolation on a straight line basis.

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

General Provisions

If you are a French resident for tax purposes on the Grant Date or on the date shares are delivered to you, any Shares delivered to you in respect of this Grant will be subject to an additional two year holding period during which such Shares may not be sold or transferred, except in case of death or Disability or if the holding requirement is waived by the Company.
