Dear Sir or Madam

Amendment to the Inventory Financing Facility Agreement (the “Amendment”)

We refer to the inventory financing credit facility agreement entered into on 21 April 2017 between Constellium Neuf Brisach and Constellium Issoire as borrowers. Constellium Holdco II B.V. as parent company and guarantor. Factofrance as agent arranger and original lender. Credit Suisse International as original lender. BNP Paribas as original lender and Deutsche Bank AG, London Branch as original lender (the “Inventory Financing Facility Agreement”).

We hereby request you to agree to

i. replace the definition of “Inventory Turn Ratio” of the Inventory Financing Facility Agreement with the following provisions

“Inventory Turn Ratio” means, in respect of any Borrower, on any Quarter Date, the ratio of (i) the sum of the aggregate amount of sales of such Borrower during the 365 days immediately preceding such Quarter Date and (ii) the average of the sum of the Inventory Value (With Dispossession) and the Inventory Value (Without Dispossession) of such Borrower as indicated in the Escrow Agent Certificates and Escrow Agent Statements (or, if not delivered in accordance with clause 5 5 2, in the statements as to the position of inventory (registre des positions de stocks)) delivered to the Agent in the three different calendar months immediately

a) in any event at the latest on the last Business Day of each calendar month with (i) an Escrow Agent Certificate countersigned by the relevant Borrower and setting out, inter alia the applicable Inventory Value (With Dispossession) and (ii) statements as to positions of inventory (registre des positions de stocks) issued by the relevant Borrower during such calendar month setting out the position of the inventory pledged under the Inventory Pledge Agreement Without Dispossession entered into by such Borrower; and

(ii) by any Borrower it being specified that, each time a Borrower wishes to deliver a Utilisation Request

A prior to such Borrower being entitled to deliver such Utilisation Request, such Borrower shall have made such a request no later than 8 Business Days preceding the contemplated Utilisation Request date and the Escrow Agent shall have provided such an Escrow Agent Statement no later than the contemplated Utilisation Request date ; and

B once the Escrow Agent has provided such Escrow Agent Statement, such Borrower may issue an Utilization Request within a month of the issuance of such Escrow Agent Statement.

c) if, at any time, the amount of all outstanding Loans made available to any Borrower is superior to 75% of the Borrowing Base Value applicable to such Borrower as at such date, every 8 Business Days, with Escrow Agent Reports countersigned by the relevant Borrower and setting out inter alia, the applicable Inventory Value (With Dispossession) and the Inventory Value (Without Dispossession);

iii. replace article 20.1.3 of the Inventory Financing Facility Agreement by the following provisions
