Holders (including subsequent transferees) of the Offered Securities will have the registration rights set forth in the registration rights agreement (the “Registration Rights Agreement”), to be dated the Closing Date (as defined below), in substantially the form of Exhibit A hereto, for so long as such Offered Securities constitute “Transfer Restricted Securities” (as defined in the Registration Rights Agreement).

(ll) To the Company’s knowledge, the section in the Offering Circular entitled “The Planned Gramercy Acquisition” does not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Neither CSFB’s consent to, nor the Purchasers’ delivery to offerees or investors of, any such amendment or supplement shall constitute a

waiver of any of the conditions set forth in Section 6. The Purchasers agree to notify the Company of the completion of the resale of the Offered Securities by the Purchasers.

(b) The Company will furnish to CSFB copies of any preliminary offering circular, the Offering Document and all amendments and supplements to such documents, in each case as soon as available and in such quantities as CSFB requests. At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company will promptly furnish or cause to be furnished to CSFB (and, upon request, to each of the other Purchasers) and, upon request of holders and prospective purchasers of the Offered Securities, to such holders and purchasers, copies of the information required to be delivered to holders and prospective purchasers of the Offered Securities pursuant to Rule 144A(d)(4) (or any successor provision thereto) in order to permit compliance with Rule 144A in connection with resales by such holders of the Offered Securities. The Company will pay the expenses of printing and distributing to the Purchasers all such documents.

(c) The Company will endeavor to arrange for the qualification of the Offered Securities (including the Guarantees) for sale under the laws of such states in the United States as CSFB reasonably designates and will continue such qualifications in effect so long as required for the resale of the Offered Securities by the Purchasers provided that the Company will not be required to qualify as a foreign corporation or to file a general consent to service of process in any such state or to subject itself to taxation in any jurisdiction where it is not now so subject.

(d) During the period of two years after the Closing Date, the Company and the Guarantors will not, nor will the Company permit any of its other subsidiaries to, and it will use its best efforts to cause its other affiliates (as defined in Rule 144 under the Securities Act) not to, resell any of the Offered Securities that have been reacquired by any of them that constitute “restricted” securities under Rule 144 except pursuant to an effective registration statement under the Securities Act.

(e) During the period of two years after the Closing Date, the Company will not take any steps that would cause the Offered Securities not to be eligible to be offered under Rule 144A.

(f) None of the Company, any Guarantor or any of the Company’s or any Guarantors’ affiliates or any person acting on its or their behalf (other than the Purchasers, as to whom the Company makes no representation) will engage in any directed selling efforts (within the meaning of Regulation S) with respect to the Offered Securities and the Company, each Guarantor and each of the Company’s and each Guarantor’s affiliates and any person acting on its or their behalf (other than the Purchasers, as to whom the Company and Guarantors make no representation) have complied and will comply with the offering restrictions requirements of Regulation S.

(g) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all expenses of the Company and the Guarantors incidental to the performance of their respective obligations under this Agreement, the Indenture and the Registration Rights Agreement including (i) the fees and expenses of the Trustee and its professional advisers; (ii) all expenses in connection with the execution, issue, authentication, packaging and initial delivery of the Offered Securities (including the Guarantees), the preparation and printing of this Agreement, the Registration Rights Agreement, the Offered Securities, the Indenture, the Offering Document and amendments and supplements thereto, and any other document relating to the issuance, offer, sale and delivery of the Offered Securities (but not including the fees for professional services of counsel to the Purchasers); (iii) the cost of qualifying the Offered Securities for trading in The Portal^SM Market (“PORTAL”) of The Nasdaq Stock Market, Inc. and any expenses incidental thereto; (iv) the cost of any advertising approved by the Company in connection with the issue of the Offered Securities; (v) any expenses (including fees and disbursements of counsel) incurred in connection with qualification of the Offered Securities

(including the Guarantees) for sale under the laws of such jurisdictions as CSFB designates and the printing of memoranda relating thereto; (vi) any fees charged by investment rating agencies for the rating of the Offered Securities; (vii) any expenses incurred in distributing the Preliminary Offering Circular and the Offering Circular (including any amendments and supplements thereto and any documents delivered therewith) to the Purchasers and potential investors; and (viii) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Offered Securities, including, without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company and any such lodging expenses of the representatives and officers of the Company and any such consultants, and the cost of any aircraft chartered in connection with the road show. It is understood, however, that, except as provided in this paragraph (g), Section 7 and Section 9, the Purchasers will pay all of their costs and expenses, including fees and disbursements of their counsel, transfer taxes payable on resale of any of the Offered Securities by them and any advertising expenses in connection with any offers they may make.

(h) In connection with the offering, until CSFB shall have notified the Company and the other Purchasers of the completion of the resale of the Offered Securities, neither the Company nor any Guarantor nor any of the Company’s or any Guarantor’s affiliates has or will, either alone or with one or more other persons, bid for or purchase for any account in which it or any of its affiliates has a beneficial interest any Offered Securities or attempt to induce any person to purchase any Offered Securities; and neither the Company nor any Guarantor nor any of the Company’s or any Guarantor’s affiliates will make bids or purchases for the purpose of creating actual, or apparent, active trading in, or of raising the price of, the Offered Securities.

(iv) on the basis of a reading of the pro forma financial statements included in the Offering Document, inquiries of officials of the Company who have responsibility for financial and accounting matters and other specified procedures, nothing came to their attention that caused them to believe that the pro forma financial statements for the year ended December 31, 2003 and the six-month period ended June 30, 2004 included in the Offering Document do not comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of the Regulation S-X and that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of those statements; and

(iv) they have compared specified dollar amounts (or percentages derived from such dollar amounts) and other financial information contained in the Offering Document and the Exchange Act Reports (in each case to the extent that such dollar amounts, percentages and other financial information are derived from the general accounting records of the Company and its subsidiaries subject to the internal controls of the Company’s accounting system or are derived directly from such records by analysis or computation) with the results obtained from inquiries, a reading of such general accounting records and other procedures specified in such letter and have found such dollar amounts, percentages and other financial information to be in agreement with such results, except as otherwise specified in such letter.

(b) Each Purchaser will severally and not jointly indemnify and hold harmless the Company and the Guarantors, their respective directors and officers and each person, if any, who controls the Company or any Guarantor within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Company or any Guarantor may become subject, under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Offering Document, or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Purchaser through CSFB specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company or any Guarantor in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Purchaser consists of (i) the following information in the Offering Document furnished on behalf of each Purchaser: the second sentence of the fourth paragraph, the fifth paragraph, the seventh paragraph (regarding market making only) and the eighth paragraph (regarding stabilizing transactions by the Purchasers) under the caption “Plan of Distribution”; and (ii) the information in the Offering Document regarding material relationship disclosure under the caption “Plan of Distribution”; provided however, that the Purchasers shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Company’s failure to perform its obligations under Section 5(a) of this Agreement.

(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from

any liability which it may have to any indemnified party otherwise than under subsection (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses. In case any such action is brought against any indemnified party, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes (i) an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault or failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantor on the one hand and the Purchasers on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors on the one hand and the Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Guarantors bear to the total discounts and commissions received by the Purchasers from the Company under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or any Guarantor or the Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities purchased by it were resold exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Purchasers’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint.

The Company, the Guarantors and the Purchasers agree that it would not be just and equitable if contribution pursuant to this Section were determined by pro rata allocation (even if the Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section. No person

guilty of fraudulent misrepresentation (within the meaning of Section 1l(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of fraudulent misrepresentation.

(e) The obligations of the Company and the Guarantors under this Section shall be in addition to any liability which they may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Purchaser within the meaning of the Securities Act or the Exchange Act; and the obligations of the Purchasers under this Section shall be in addition to any liability which the respective Purchasers may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Company or any Guarantor within the meaning of the Securities Act or the Exchange Act.

8. Default of Purchasers. If any Purchaser or Purchasers default in their obligations to purchase Offered Securities hereunder on the Closing Date and the aggregate principal amount of the Offered Securities that such defaulting Purchaser or Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of the Offered Securities that the Purchasers are obligated to purchase on the Closing Date, CSFB may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Purchasers, but if no such arrangements are made by the Closing Date, the non-defaulting Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Purchasers agreed but failed to purchase on the Closing Date. If any Purchaser or Purchasers so default and the aggregate principal amount of the Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of the Offered Securities that the Purchasers are obligated to purchase on the Closing Date and arrangements satisfactory to CSFB and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Purchaser, the Company or the Guarantors, except as provided in Section 9. As used in this Agreement, the term “Purchaser” includes any person substituted for a Purchaser under this Section. Nothing herein will relieve a defaulting Purchaser from liability for its default.

9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Purchaser, the Company, any Guarantor or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated by the Purchasers, or any of them, because of any failure or refusal on the part of the Company or any Guarantor to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company or any Guarantor shall be unable to perform its obligations under this Agreement, the Company and the Guarantors jointly and severally agree that they will reimburse the Purchasers or such Purchasers as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Purchasers in connection with this Agreement or the offering contemplated hereunder.

10. Notices. All communications hereunder will be in writing and, if sent to the Purchasers will be mailed, delivered or telegraphed and confirmed to the Purchasers c/o Credit Suisse First Boston LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: Transactions Advisory Group, or, if sent to the Company or any Guarantor, will be mailed, delivered or telegraphed and confirmed to it at Century Aluminum Company, 2511 Garden Road, Building A, Suite 200, Monterey, CA, 93940, Attention: Gerald J. Kitchen with a copy to Curtis, Mallet-Prevost, Colt & Mosle LLP, Attention: Jeffrey N. Ostrager; provided, however, that any notice to a Purchaser pursuant to Section 7 will be mailed, delivered or telegraphed and confirmed to such Purchaser.

11. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder.

12. Representation of Purchasers. You will act for the several Purchasers in connection with this purchase, and any action under this Agreement taken by you jointly or by CSFB will be binding upon all the Purchasers.

13. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

14. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without regard to principles of conflicts of laws.

The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

If the foregoing is in accordance with the Purchasers’ understanding of our agreement, kindly sign and return to the Company one of the counterparts hereof whereupon it will become a binding agreement among the Company, the Guarantors and the several Purchasers in accordance with its terms.
