AMENDMENT NO. 2 TO
SECOND AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT


THIS AMENDMENT NO. 2 TO SECOND AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT (this "Amendment") is entered into as of June 15, 2021, by and among the Lenders party hereto, WELLS FARGO CAPITAL FINANCE, LLC, a Delaware limited liability company, as the agent for the Lenders (in such capacity, "Agent"), CENTURY ALUMINUM COMPANY, a Delaware corporation ("Century"), CENTURY ALUMINUM OF SOUTH CAROLINA, INC. (successor in interest to Berkeley Aluminum, Inc.), a Delaware corporation ("Century South Carolina"), CENTURY ALUMINUM OF KENTUCKY GENERAL PARTNERSHIP, a Kentucky general partnership ("Century of Kentucky GP"), NSA GENERAL PARTNERSHIP, a Kentucky general partnership ("NSA"), and CENTURY ALUMINUM SEBREE LLC, a Delaware limited liability company ("Century Sebree"; and together with Century, Century South Carolina, Century of Kentucky GP and NSA, each a "Borrower" and collectively the "Borrowers"). 
WHEREAS, Borrowers, Agent, and Lenders are parties to that certain Second Amended and Restated Loan and Security Agreement dated as of May 16, 2018 (as amended, modified or supplemented from time to time, the "Loan Agreement"); and
WHEREAS, Borrowers, Agent and Lenders have agreed to amend the Loan Agreement, subject to the terms and conditions contained herein.
NOW THEREFORE, in consideration of the premises and mutual agreements herein contained, the parties hereto agree as follows:
1.Defined Terms.  Unless otherwise defined herein, capitalized terms used herein shall have the meanings ascribed to such terms in the Loan Agreement.
2.Amendments to Loan Agreement.  Subject to the satisfaction of the conditions set forth in Section 4 below and in reliance upon the representations and warranties of Borrowers set forth in Section 5 below, the Loan Agreement is hereby amended as follows: 
(a)The Loan Agreement is hereby amended to insert a new Section 2.1.4 at the end of Section 2.1 thereof as follows: 
        2.1.4.     Rates. The interest rate on LIBOR Rate Loans and Base Rate Loans (when determined by reference to clause (b) of the definition of Base Rate) may be determined by reference to LIBOR, which is derived from the London interbank offered rate.  The London interbank offered rate is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market.  On March 5, 2021, ICE Benchmark Administration (“IBA”), the administrator of the London interbank 








offered rate, and the Financial Conduct Authority (the “FCA”), the regulatory supervisor of IBA, announced in public statements (the “Announcements”) that the final publication or representativeness date for the London interbank offered rate for Dollars for: (a) 1-week and 2-month tenor settings will be December 31, 2021 and (b) overnight, 1-month, 3-month, 6-month and 12-month tenor settings will be June 30, 2023. No successor administrator for IBA was identified in such Announcements.  As a result, it is possible that commencing immediately after such dates, the London interbank offered rate for such tenors may no longer be available or may no longer be deemed a representative reference rate upon which to determine the interest rate on LIBOR Rate Loans or Base Rate Loans (when determined by reference to clause (b) of the definition of Base Rate). There is no assurance that the dates set forth in the Announcements will not change or that IBA or the FCA will not take further action that could impact the availability, composition or characteristics of any London interbank offered rate. Public and private sector industry initiatives have been and continue, as of the date hereof, to be underway to implement new or alternative reference rates to be used in place of the London interbank offered rate.  In the event that the London interbank offered rate or any other then-current Benchmark is no longer available or in certain other circumstances set forth in Section 3.13.3, such Section 3.13.3 provides a mechanism for determining an alternative rate of interest. The Agent will notify the Borrowers, pursuant to Section 3.13.3, of any change to the reference rate upon which the interest rate on LIBOR Rate Loans and Base Rate Loans (when determined by reference to clause (b) of the definition of Base Rate) is based.  However, the Agent does not warrant or accept any responsibility for, and shall not have any liability with respect to, (i) the administration of, submission of, calculation of or any other matter related to the London interbank offered rate or other rates in the definition of “LIBOR” or with respect to any alternative, comparable or successor rate thereto, or replacement rate thereof (including any then-current Benchmark or any Benchmark Replacement), including whether the composition or characteristics of any such alternative, successor or replacement reference rate (including any Benchmark Replacement), as it may or may not be adjusted pursuant to Section 3.13.3, will be similar to, or produce the same value or economic equivalence of, LIBOR or any other Benchmark, or have the same volume or liquidity as did the London interbank offered rate or any other Benchmark prior to its discontinuance or unavailability, or (ii) the effect, implementation or composition of any Benchmark Replacement Conforming Changes.


(b)The Loan Agreement is hereby amended to insert a new Section 3.13.3 at the end of Section 3.13 thereof as follows:
        3.13.3    Effect of Benchmark Transition Event.
(i)    (A)    Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Loan Document (and any Hedge Agreement shall 
- 2 -






be deemed not to be a “Loan Document” for purposes of this Section 3.13.3) if a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (a)(1) or (a)(2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document and (y) if a Benchmark Replacement is determined in accordance with clause (a)(3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to the Lenders without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Lenders comprising the Majority Lenders. 
    (B)    Notwithstanding anything to the contrary herein or in any other Loan Document, if a Term SOFR Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder or under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings, without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document; provided that this clause (B) shall not be effective unless the Agent has delivered to the Lenders and the Borrowers a Term SOFR Notice.  For the avoidance of doubt, the Agent shall not be required to deliver a Term SOFR Notice after a Term SOFR Transition Event and may elect or not elect to do so in its sole discretion.
(ii)    Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document.
(iii)    Notices; Standards for Decisions and Determinations. The Agent will promptly notify the Borrowers and the Lenders of (A) any occurrence of a 
- 3 -






Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date, (B) the implementation of any Benchmark Replacement, (C) the effectiveness of any Benchmark Replacement Conforming Changes, (D) the removal or reinstatement of any tenor of a Benchmark pursuant to Section 3.13.3(iv) below and (E) the commencement or conclusion of any Benchmark Unavailability Period.  Any determination, decision or election that may be made by the Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 3.13.3, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Loan Document, except, in each case, as expressly required pursuant to this Section 3.13.3.


(iv)     Unavailability of Tenor of Benchmark.  Notwithstanding anything to the contrary herein or in any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (A) if the then-current Benchmark is a term rate (including Term SOFR or the LIBOR Rate) and either (1) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Agent in its reasonable discretion or (2) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is or will be no longer representative, then the Agent may modify the definition of “Interest Period” for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (B) if a tenor that was removed pursuant to clause (A) above either (1) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (2) is not, or is no longer, subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark Replacement), then the Agent may modify the definition of “Interest Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor.


(v)    Benchmark Unavailability Period. Upon the Borrowers' receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrowers may revoke any request for a borrowing of, conversion to or continuation of LIBOR Rate Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrowers will be deemed to have converted any such request into a request for a borrowing of or conversion to Base Rate Loans. During any Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of the Base Rate based upon the then-current Benchmark or such 
- 4 -






tenor for such Benchmark, as applicable, will not be used in any determination of the Base Rate.


(vi)    London Interbank Offered Rate Benchmark Transition Event.  On March 5, 2021, the IBA, the administrator of the London interbank offered rate, and the FCA, the regulatory supervisor of the IBA, made the Announcements that the final publication or representativeness date for (I) 1-week and 2-month London interbank offered rate tenor settings will be December 31, 2021 and (II) overnight, 1-month, 3-month, 6-month and 12-month London interbank offered rate tenor settings will be June 30, 2023.  No successor administrator for the IBA was identified in such Announcements.  The parties hereto agree and acknowledge that the Announcements resulted in the occurrence of a Benchmark Transition Event with respect to the London interbank offered rate pursuant to the terms of this Agreement and that any obligation of the Agent to notify any parties of such Benchmark Transition Event pursuant to clause (iii) of this Section 3.13.3 shall be deemed satisfied.


(c)    Section 8.2.2 of the Loan Agreement is hereby amended to amend and restate clause (ii) in its entirety as follows:

- 6 -






Benchmark - initially, the LIBOR Rate; provided that if a Benchmark Transition Event, a Term SOFR Transition Event, or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred with respect to the LIBOR Rate or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement to the extent that such Benchmark Replacement has replaced such prior benchmark rate pursuant to Section 3.13.3(i).
Benchmark Replacement - for any Available Tenor,
(a)    with respect to any Benchmark Transition Event or Early Opt-in Election, the first alternative set forth in the order below that can be determined by the Agent for the applicable Benchmark Replacement Date:

(b)   the spread adjustment (which may be a positive or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Interest Period that would apply to the fallback rate for a derivative transaction referencing the ISDA Definitions to be effective upon an index cessation event with respect to such Available Tenor of such Benchmark; 


(2)for purposes of clause (a)(3) of the definition of “Benchmark Replacement,” the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by the Agent and the Borrower Representative giving due consideration to (i) any selection or recommendation of a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Available Tenor of such Benchmark with the applicable Unadjusted Benchmark Replacement by the Relevant Governmental Body on the applicable Benchmark Replacement Date or (ii) any evolving or then-prevailing market convention for determining a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Available Tenor of such Benchmark with the applicable Unadjusted Benchmark Replacement for Dollar-denominated syndicated credit facilities; and
(3)for purposes of clause (b) of the definition of “Benchmark Replacement,” the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Interest Period that has been selected or recommended by the Relevant Governmental Body for the replacement of such Available Tenor of the LIBOR Rate with a SOFR-based rate;
provided that, (x) in the case of clause (1) above, such adjustment is displayed on a screen or other information service that publishes such Benchmark Replacement Adjustment from time to time as selected by the Agent in its reasonable discretion and (y) if the then-current Benchmark is a term rate, more than one tenor of such 
- 8 -






Benchmark is available as of the applicable Benchmark Replacement Date and the applicable Unadjusted Benchmark Replacement that will replace such Benchmark in accordance with Section 3.13.3(i) will not be a term rate, the Available Tenor of such Benchmark for purposes of this definition of “Benchmark Replacement Adjustment” shall be deemed to be, with respect to each Unadjusted Benchmark Replacement having a payment period for interest calculated with reference thereto, the Available Tenor that has approximately the same length (disregarding business day adjustments) as such payment period.
Benchmark Replacement Conforming Changes - with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “Base Rate,” the definition of “Business Day,” the definition of “Interest Period,” timing and frequency of determining rates and making payments of interest, timing of borrowing requests or prepayment, conversion or continuation notices, length of lookback periods, the applicability of breakage provisions, and other technical, administrative or operational matters) that the Agent decides may be appropriate to reflect the adoption and implementation of such Benchmark Replacement and to permit the administration thereof by the Agent in a manner substantially consistent with market practice (or, if the Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Agent determines that no market practice for the administration of such Benchmark Replacement exists, in such other manner of administration as the Agent decides is reasonably necessary in connection with the administration of this Agreement and the other Loan Documents).

- 9 -






fifth (5th) Business Day after the date notice of such Early Opt-in Election is provided to the Lenders, written notice of objection to such Early Opt-in Election from Lenders comprising the Majority Lenders.
