ARTICLE VI

Allocations and Distributions

6.1 Membership Interests. The Membership Interest of each of the Members shall be as set forth on Schedule 1 hereto, as advised from time to time by the Manager, in connection with the admission or withdrawal of a Member, the transfer of an interest in the Company or similar event.

6.2 Allocations of Net Profits. Except as otherwise provided in this Article, the Net Profits for each Fiscal Year shall be allocated to Members in the ratio of their Membership Interests.

6.3 Allocation of Net Losses. Except as otherwise provided in this Article, the Net Losses for each Fiscal Year shall be allocated to Members in the ratio of their Membership Interests.

6.4 Allocation of Taxable Income. Any item of taxable income, gain, loss or deduction of the Company as determined for Federal income tax purposes shall be allocated in the same manner as the corresponding income, gain, loss or deduction is allocated under Sections 6.2 and 6.3 hereof, except to the extent otherwise required by the principles of, and Treasury Regulations under, Section 704(b) and (c) of the Code. Any Member who unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulation Section 1.704-l(b)(2)(ii)(d)(4), (5) or (6) that creates or increases a deficit balance in its Capital Account (adjusted by any amount that a Member is treated as being obligated to restore under Sections 1-704-2(g) and (i)(5) of the Treasury Regulations) shall be specially allocated gross income of the Company if necessary to eliminate such deficit balance consistent with the “qualified income offset” provisions of Section 1.704-l(b)(2)(ii)(d) of the Treasury Regulations. Any special allocation pursuant to the preceding sentence shall be taken into account in computing subsequent allocations pursuant to this Article VI, so that to the extent it is in accordance with the Treasury Regulations under Section 704(b) of the Code, the net adjustment to the Capital Account of each Member pursuant to the allocations of this Article VI shall be equal to the net adjustment to such Capital Account of each Member pursuant to the provisions of this Article VI if the allocations pursuant to the preceding sentence had not occurred.

6.5 Minimum Gain Chargeback. Notwithstanding anything to the contrary in this Article VI, if during any Fiscal Year there is a net decrease in Company Minimum Gain (as defined in Treasury Regulation Section 1.704-2(d)), each Member shall be allocated gross income for such Fiscal Year (and, if necessary subsequent Fiscal Years) in the manner provided for in Treasury Regulations Section 1.704-2(f). Notwithstanding anything to the contrary in this Article VI, if during any Fiscal Year there is a net decrease in a Member’s “Partner Nonrecourse Debt Minimum Gain” attributable to such Member’s “Partner Nonrecourse Debt” (as such terms are defined in Treasury Regulations Section 1.704-2(i)(2) and (b)(4), respectively), the Members shall be allocated gross income for such Fiscal Year (and, if necessary subsequent Fiscal Years) to the extent and in the manner provided for in Treasury Regulations Section 1.704-2(i).

6.6 Nonrecourse Deductions. Gross deductions that are Nonrecourse Deductions (as defined in Treasury Regulation Section 1.704-2(b)(1)) for a Fiscal Year shall be allocated to each Member in the same ratio as Net Profit or Net Loss is allocated for such Fiscal Year.

6.7 Distributions. The Manager shall be solely responsible for making all determinations of amounts and timing of all distributions to Members. The Manager shall have sole discretion to determine amounts available for distribution. Distributions shall be made at such times and intervals as the Manager in his or her sole discretion shall determine. All distributions shall be made to the Members pro rata in proportion to their Membership Interests. In the sole discretion of the Manager, securities, assets or other property in kind may be distributed to the Members. Each distribution in kind of securities, assets or other property shall be distributed in accordance with this paragraph as if there had been a sale of such property for an amount of cash equal to the Fair Market Value of such property followed by an immediate

distribution of such cash proceeds. Distributions consisting of cash, securities, assets and/or other property shall be made, to the extent practicable, in pro rata portions as to each Member receiving such distributions. For purposes of the preceding sentence, securities, assets or other property having a different tax basis than like securities, assets or other property shall be considered to be securities, assets or other property of a different type.

6.8 Interest on and Return of Capital Contributions. No Member shall be entitled to interest on its Capital Contributions or to a return of its Capital Contributions, except as specifically set forth in this Agreement.

ARTICLE VII

Taxes

7.1 Tax Returns. The Manager shall cause to be prepared and filed, at the expense of the Company, all necessary federal and state income tax returns for the Company and all tax reports to Members required to be prepared under the Code. Each Member shall furnish to the Company all pertinent information in its possession relating to the Company that is necessary to enable the Company’s income tax returns to be properly prepared and filed.

7.2 Tax Matters Partner. The Members hereby designate the The Renco Group, Inc. to be the “tax matters partner” of the Company pursuant to Section 6231(a)(7) of the Code. The tax matters partner shall have full discretion to make any elections under the Code.

ARTICLE VIII

Transferability

8.1 Member Transfers. No Member may sell, assign, transfer, convey or dispose of all or any portion of his interest in the Company or any rights or benefits with respect thereto, except with the consent of a majority in Membership Interests of the non-transferring Members, which consent may be given or withheld in their sole discretion, provided, however, that Doe Run may pledge its interest in the Company to State Street, as Agent for the benefit of any Secured Persons.

8.2 Transferee Not a Member. No Person acquiring an assignment or transfer of an interest in the Company other than a Member shall become a Member except pursuant to Sections 3.2 and 8.1 of this Agreement. If no such approval is obtained, such Person’s interest in the Company shall only entitle such Person to receive the distributions and allocations of profits and losses to which the Member from which such Person received such interest in the Company would be entitled. Any such approval shall be subject to any terms and conditions imposed by a majority in Membership Interests of the non-transferring Members. No Person may be admitted as a Member pursuant to this Article VIII or Article III until such Person executes and delivers to the Company an agreement, in form and substance satisfactory to the Manager, binding such Person to the terms and conditions of this Agreement as if such Person had been named a Member herein.

8.3 Membership Interest. Any Membership interest in the Company shall be evidenced by a certificate substantially in the form attached as Exhibit A. The Company shall issue to each Member a certificate to evidence its membership interest.

Upon a liquidation of the Company within the meaning of Section 1.704-l(b)(2)(ii)(g) of the Treasury Regulations, if any Member has a deficit Capital Account (after giving effect to all contributions, distributions, allocations and other adjustments for all Fiscal Years, including the Fiscal Year in which such liquidation occurs), the Member shall have no obligation to make any Capital Contribution, and the negative balance of any Capital Account shall not be considered a debt owed by the Member to the Company or to any other Person for any purpose.

9.4 Nonrecourse to Other Members. Except as provided by applicable law or as expressly provided in this Agreement, upon dissolution, each Member shall receive a return of its Capital Contribution solely from the assets of the Company. If the assets of the Company remaining after the payment or discharge of the debts and liabilities of the Company are insufficient to return any Capital Contribution of any Member, such Member shall have no recourse against any other Member.
