     THIS SUPPLEMENTAL INDENTURE NO. 4 (this “Supplemental Indenture”), entered into as of

RECITALS

     WHEREAS, the Company and the Trustee entered into the Indenture, dated as of August 9, 2004
(the “Original Indenture,” as amended by Supplemental Indenture No. 1, dated as of October 26,

2004, among the Company, the Guarantors party thereto and the Trustee, Supplemental Indenture No.
3, dated as of July 25, 2005, among the Company, Century Aluminum of Kentucky LLC and the Trustee,

     WHEREAS, the Company has agreed in Section 6.09 of the Indenture to cause certain of its
Subsidiaries to provide Securities Guaranties in certain circumstances; and

     WHEREAS, the Undersigned is required pursuant to such Section 6.09 to execute and deliver this
Supplemental Indenture to evidence its Securities Guaranty.

AGREEMENT

     NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained and
intending to be legally bound, the parties to this Supplemental Indenture, effective from and after
December 20, 2005, hereby agree as follows:

     Section 1. Capitalized terms used herein and not otherwise defined herein are used as defined
in the Indenture.

     Section 2. The Undersigned, by its execution of this Supplemental Indenture, agrees to be a
Guarantor under the Indenture on the terms set forth below.

     Section 3. Subject to the provisions in this Supplemental Indenture, the Guarantor hereby
irrevocably and unconditionally guarantees, jointly and severally, on a senior unsecured basis, the
full and punctual payment (or delivery, as the case may be), if and when due, of (i) the principal
amount or interest due on any Security, whether on the Final Maturity Date, upon redemption or
repurchase, or otherwise, (ii) the Make Whole Premium payable, if any, on any Security, and (iii)
all other amounts payable by the Company under the Indenture (including, without limitation, the
Company’s obligation to deliver Cash, Common Stock, or other securities, assets or property
(including Cash) upon conversion of the Securities). Upon failure by the Company to pay (or
deliver, as the case may be) punctually any such amount if and when due, the Guarantor shall
forthwith on demand pay (or deliver, as the case may be) the amount (or consideration) not so paid
(or delivered) at the place and in the manner specified in the

-2-

 

Indenture. To the extent that the Company has an election to deliver the form of payment, the
Guarantor shall have the same right of election.

     Section 4. The obligations of the Guarantor are unconditional and absolute and, without
limiting the generality of the foregoing, will not be released, discharged or otherwise affected by

     (i) any extension, renewal, settlement, compromise, waiver or release in respect of any
obligation of the Company under the Indenture or any Security, by operation of law or
otherwise;

     (ii) any modification or amendment of or supplement to the Indenture or any Security;

     (iii) any change in the corporate existence, structure or ownership of the Company, or
any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Company
or its assets or any resulting release or discharge of any obligation of the Company
contained in the Indenture or any Security;

     (iv) the existence of any claim, set-off or other rights which the Guarantor may have
at any time against the Company, the Trustee or any other Person, whether in connection with
the Indenture or any unrelated transactions; provided that nothing herein prevents the
assertion of any such claim by separate suit or compulsory counterclaim;

     (v) any invalidity or unenforceability relating to or against the Company for any
reason of the Indenture or any Security, or any provision of applicable law or regulation
purporting to prohibit the payment by the Company of the principal amount, Make Whole
Premium, if any, or interest due on any Security or any other amount payable by the Company
under the Indenture; or

     (vi) any other act or omission to act or delay of any kind by the Company, the Trustee
or any other Person or any other circumstance whatsoever which might, but for the provisions
of this paragraph, constitute a legal or equitable discharge of or defense to the
Guarantor’s obligations hereunder.

     Section 5. The Guarantor’s obligations under its Securities Guaranty will remain in full
force and effect until the principal of, Make Whole Premium, if any, and interest on the Securities
and all other amounts payable by the Company (including, without limitation, the Company’s
obligation to deliver Cash, Common Stock, or other securities, assets or property (including Cash)
upon conversion of the Securities) under the Indenture have been paid in full. If at any time any
payment of the principal of, Make Whole Premium, if any, or interest on any Security or any other
amount payable by the Company (including, without limitation, the Company’s obligation to deliver
Cash, Common Stock, or other securities, assets or property (including Cash) upon conversion of the
Securities) under the Indenture is rescinded or must be otherwise restored or returned upon the
insolvency, bankruptcy or reorganization of the Company or otherwise, the Guarantor’s obligations
hereunder with respect to such payment will be reinstated as though such payment had been due but
not made at such time.

-3-

 

     Section 6. Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest
and any notice not provided for herein, as well as any requirement that at any time any action be
taken by any Person against the Company or any other Person.

     Section 7. Upon making any payment with respect to any obligation of the Company pursuant to
this Supplemental Indenture, the Guarantor making such payment will be subrogated to the rights of
the payee against the Company with respect to such obligation; provided that the Guarantor may not
enforce either any right of subrogation, or any right to receive payment in the nature of
contribution, or otherwise, from any other Guarantor, with respect to such payment so long as any
amount payable by the Company hereunder or under the Securities remains unpaid.

     Section 8. If acceleration of the time for payment of any amount payable by the Company under
the Indenture or the Securities is stayed upon the insolvency, bankruptcy or reorganization of the
Company, all such amounts otherwise subject to acceleration under the terms of the Indenture are
nonetheless payable by the Guarantor hereunder forthwith on demand by the Trustee or the Holders.

     Section 9. Notwithstanding anything to the contrary in this Supplemental Indenture, the
Guarantor, and by its acceptance of Securities, each Holder, hereby confirms that it is the
intention of all such parties that the Securities Guaranty of such Guarantor not constitute a
fraudulent conveyance under applicable fraudulent conveyance provisions of the United States
Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the
Trustee, the Holders and the Guarantor hereby irrevocably agree that the obligations of the
Guarantor under its Securities Guaranty are limited to the maximum amount that would not render the
Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of
the United States Bankruptcy Code or any comparable provision of state law.

     Section 10. The execution by the Undersigned of this Supplemental Indenture evidences the
Securities Guaranty of such Guarantor, whether or not the person signing as an officer of the
Guarantor still holds that office at the time of authentication of any Security. The delivery of
any Security by the Trustee after authentication constitutes due delivery of the Securities
Guaranty set forth in the Indenture on behalf of the Guarantor.

     Section 11. The Securities Guaranty of the Guarantor will terminate and be automatically
released upon the release or discharge of the guarantee of the Senior Notes of such Guarantor as
set forth in Section 6.09(b) of the Indenture.

     Section 12. This Supplemental Indenture shall be governed by and construed in accordance with
the laws of the State of New York.

     Section 13. This Supplemental Indenture may be signed in various counterparts which together
will constitute one and the same instrument.

     Section 14. This Supplemental Indenture is an amendment supplemental to the Indenture and the
Indenture and this Supplemental Indenture will henceforth be read together.

     Section 15. The recitals contained in this Supplemental Indenture shall be taken as the
statements of the Company and the Guarantors, and the Trustee assumes no responsibility for

-4-

 

their correctness. The Trustee makes no representations as to the validity or sufficiency of
this Supplemental Indenture.
