Notwithstanding anything to the contrary herein, a merger of DRA with and into the Company or Renco shall not constitute a “Change of Control” hereunder. In deeming a sale of assets by a corporation to be a sale of “all or substantially all its assets” under New York law, the focus is not on the dollar amount involved, but rather on the nature of the sale as it affects the ability of the corporation to conduct the business for which it was established. If the sale of certain assets is significant enough to render the corporation unable, in whole or in part, to accomplish the purposes or objects for which it was incorporated, such sale is not in the ordinary course of business and would be deemed a sale of “all or substantially all of its assets.” So long as the corporation remains able to conduct its business, the sale of such corporation’s assets, even its sole asset, may be within the ordinary course of business and will not be deemed a sale of “all or substantially all its assets.”

“Change of Control Date” has the meaning provided in Section 4.15(a).

“Change of Control Offer” has the meaning provided in Section 4.15(a).

“Change of Control Payment Date” has the meaning provided in Section 4.15(b)(2).

“Collateral Account” has the meaning provided in Section 11.01.

“Collateral Agent” shall mean State Street Bank and Trust Company, a Massachusetts trust company, as Trustee, in its capacity as collateral agent under the Collateral Documents, and any successor thereto in such capacity.

“Collateral Documents” means, collectively, the Security Agreement, the Mortgage, the Intercreditor Agreement and all other instruments or documents entered into or delivered in connection with any of the foregoing, as such agreements, instruments or documents may be amended, amended and restated, supplemented or otherwise modified from time to time.

“Collateral Proceeds” has the meaning provided in Section 4.16 (a)(ii).

“Company” means the party named as such in this Indenture until a successor replaces it pursuant to this Indenture and thereafter means such successor.

“Company Order” means a written order or request signed in the name of the Company by its President or a Vice President, and by its Treasurer, an Assistant Treasurer, its Secretary or an Assistant Secretary, and delivered to the Trustee.

“Consolidated EBITDA” means, with respect to any person, for any period, the sum (without duplication) of (i) Consolidated Net Income, (ii) to the extent Consolidated Net Income has been reduced thereby, all income taxes of such person and its Subsidiaries (Restricted Subsidiaries, in the case of the Company) paid or accrued in accordance with GAAP for such period (other than income taxes attributable to extraordinary, unusual or non-recurring gains or losses), Consolidated Interest Expense (net of any interest income), amortization expense (including amortization of deferred financing costs) and depletion and depreciation expense and (iii) other non-cash items (other than non-cash interest) reducing Consolidated Net Income (including, without limitation, any non-cash charges in respect of post-employment benefits for health care, life insurance and long-term disability benefits required in accordance with GAAP) less other non-cash items increasing Consolidated Net Income, all as determined on a consolidated basis for such person and its Subsidiaries (Restricted Subsidiaries, in the case of the Company) in accordance with GAAP.

“Consolidated Fixed Charge Coverage Ratio” means, with respect to any person, the ratio of Consolidated EBITDA of such person during the four full fiscal quarters (the “Four Quarter Period”) ending on or prior to the date of the transaction giving rise to the need to calculate the Consolidated Fixed Charge Coverage Ratio (the “Transaction Date”) to Consolidated Fixed Charges of such person for the Four Quarter Period. For purposes of this definition, if the Transaction Date occurs prior to the date on which four full fiscal quarters have elapsed subsequent to the Issue Date and financial statements with respect thereto are available, “Consolidated EBITDA” and “Consolidated Fixed Charges” shall be calculated, in the case of the Company, after giving effect on a pro forma basis to the issuance of the Securities ] (if four full fiscal quarters have not elapsed subsequent to the issue date of the Existing Securities and on or prior to the Transaction Date) and the application of the net proceeds therefrom as if the Securities were issued on the first day of the Four Quarter Period. In addition to and without limitation of the foregoing, for purposes of this definition, “Consolidated EBITDA” and “Consolidated Fixed Charges” shall be calculated after giving effect on a pro forma basis for the period of such calculation to (i) the incurrence of any Indebtedness (and the application of the net proceeds therefrom) of such person or any of its Subsidiaries (Restricted Subsidiaries, in the case of the Company) giving rise to the need to make such calculation and any incurrence of other Indebtedness at any time on or after the first day of the Four Quarter Period and on or prior to the Transaction Date (the “Reference Period”), as if such incurrence occurred on the first day of the

Reference Period and (ii) any Asset Sales or Asset Acquisitions (including, without limitation, any Asset Acquisition giving rise to the need to make such calculation as a result of such person or one of its Subsidiaries (Restricted Subsidiaries, in the case of the Company)(including any person who becomes a Subsidiary (Restricted Subsidiary, in the case of the Company) as a result of the Asset Acquisition) incurring, assuming or otherwise being liable for Acquired Indebtedness) occurring during the Reference Period, as if such Asset Sale or Asset Acquisition (including the incurrence, assumption or liability for any such Indebtedness or Acquired Indebtedness) occurred on the first day of the Reference Period. If such person or any of its Subsidiaries (Restricted Subsidiaries, in the case of the Company) directly or indirectly guarantees Indebtedness of a third person, the preceding sentence shall give effect to the incurrence of such guaranteed Indebtedness as if such person or any Subsidiary (Restricted Subsidiary, in the case of the Company) of such person had directly incurred or otherwise assumed such guaranteed Indebtedness. Furthermore, in calculating “Consolidated Fixed Charges” for purposes of determining the denominator (but not the numerator) of this “Consolidated Fixed Charge Coverage Ratio,” (1) interest on Indebtedness determined on a fluctuating basis as of the Transaction Date and which will continue to be so determined thereafter shall be deemed to have accrued at a fixed rate per annum equal to the rate of interest on such Indebtedness in effect on the Transaction Date, and (2) notwithstanding clause (1) above, interest on Indebtedness determined on a fluctuating basis, to the extent such interest is covered by agreements relating to Interest Rate Protection Obligations, shall be deemed to accrue at the rate per annum resulting after giving effect to the operation of such agreements.

“Consolidated Fixed Charges” means, with respect to any person for any period, the sum of, without duplication, the amounts for such period, taken as a single accounting period, of (i) Consolidated Interest Expense of such person (net of any interest income) less non-cash amortization of deferred financing costs and (ii) the product of (x) the amount of all dividends declared, paid or accrued on Preferred Stock of such person during such period times (y) a fraction, the numerator of which is one and the denominator of which is one minus the then current effective consolidated Federal, state, local and foreign tax rate (expressed as a decimal number between 1 and 0) of such person during such period (as reflected in the audited consolidated financial statements of such person for the most recently completed fiscal year).

“Consolidated Interest Expense” means, with respect to any person for any period, without duplication, the sum of (i) the interest expense of such person and its Subsidiaries (Restricted Subsidiaries, in the case of the Company) for such period as determined on a consolidated basis in accordance with GAAP consistently applied, including, without limitation, (a) any amortization of debt discount, (b) the net cost under Interest Rate Protection Obligations (including any amortization of discounts), (c) the interest portion of any deferred payment obligation and (d) all accrued interest, and (ii) the interest component of Capitalized Lease Obligations paid, accrued and/or scheduled to be paid or accrued by such person and its Subsidiaries (Restricted Subsidiaries, in the case of the Company) during such period as determined on a consolidated basis in accordance with GAAP consistently applied.

“Consolidated Net Income” means, with respect to any person for any period, the net income (or loss) of such person and its Subsidiaries (Restricted Subsidiaries, in the case of the Company), on a consolidated basis for such period determined in accordance with GAAP; provided that (i) the net income of any person in which such person or any Subsidiary (Restricted

Subsidiary, in the case of the Company) of such person has an ownership interest with a third party (other than a person that meets the definition of a Wholly-Owned Subsidiary (Wholly-Owned Restricted Subsidiary, in the case of the Company)) shall be included only to the extent of the amount that has actually been received by such person or its Wholly-Owned Subsidiaries (Wholly-Owned Restricted Subsidiaries, in the case of the Company) in the form of dividends or other distributions during such period (subject to, in the case of any dividend or distribution received by a Wholly-Owned Subsidiary (Wholly-Owned Restricted Subsidiary, in the case of the Company) of such person, the restrictions set forth in clause (ii) below) and (ii) the net income of any Subsidiary (Restricted Subsidiary, in the case of the Company) of such person that is subject to any restriction or limitation on the payment of dividends or the making of other distributions shall be excluded to the extent of such restriction or limitation; provided, however, that consolidated net income shall include the income of Doe Run Peru and its subsidiaries to the extent the payment of such income in the form of dividends or other such distributions is prohibited solely by the terms of the Peruvian Revolving Credit Facility; provided, further that there shall be excluded (a) the net income (or loss) of any person (acquired in a pooling of interests transaction) accrued prior to the date it becomes a Subsidiary (Restricted Subsidiary, in the case of the Company) of such person or is merged into or consolidated with such person or any Subsidiary (Restricted Subsidiary, in the case of the Company) of such person, (b) any gain (or loss) (and related tax effects) resulting from an Asset Sale by such person or any of its Subsidiaries (Restricted Subsidiaries, in the case of the Company) (c) any extraordinary, unusual or nonrecurring gains or losses (and related tax effects) in accordance with GAAP (d) the effects of any adjustments to income for unrealized gains and losses or any non-cash adjustments to income or expenses required by Statement No. 133 (as modified by Statement No. 138) and No. 15 of the Financial Accounting Standards Board and (e) any compensation-related expenses arising as a result of the application of the net proceeds from the issuance of the Securities or the Existing Securities. For purposes of Section 4.03, the amortization of deferred financing costs relating to the issuance of the Securities and the Existing Securities shall be excluded from this definition of “Consolidated Net Income.”

“Consolidated Net Worth” means, with respect to any person at any date, the sum of (a) the consolidated shareholders’ equity of such person less the amount of such shareholders’ equity attributable to (i) Disqualified Capital Stock of such person and its Subsidiaries (Restricted Subsidiaries, in the case of the Company), as determined on a consolidated basis in accordance with GAAP consistently applied and (ii) the effects of any adjustments for unrealized gains and losses required by Statement No. 133 (as modified by Statement No. 138) of the Financial Accounting Standards Board and (b) the amount of any Preferred Stock of such person not included in the shareholders’ equity of such person in accordance with GAAP, which Preferred Stock does not constitute Disqualified Capital Stock.

THE SECURITIES

SECTION 2.01. Form and Dating.

The Securities and the Trustee’s certificate of authentication with respect thereto shall be substantially in the form of Exhibit A hereto. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage. The Company and the Trustee shall approve the form of the Securities and any notation, legend or endorsement on them. Each Security shall be dated the date of its authentication, shall bear interest from the applicable date and shall be payable on the Interest Payment Dates and the Maturity Date. Each Security shall have an executed Guarantee from each of the Guarantors endorsed thereon substantially in the form of Exhibit B hereto.

The terms and provisions contained in the Securities shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.

SECTION 2.02. Execution and Authentication.

Two Officers, or an Officer and an Assistant Secretary, shall sign, or one Officer shall sign and one Officer or an Assistant Secretary for the Company (each of whom shall have been duly authorized by all requisite corporate actions) shall attest to, the Securities for the Company by manual or facsimile signature.

An Officer shall sign for each Guarantor (which officer shall have been duly authorized by all requisite corporate actions) the Guarantees for such Guarantor by manual or facsimile signature.

If an Officer whose signature is on a Security or a Guarantee was an Officer at the time of such execution but no longer holds that office at the time the Trustee authenticates the Security, the Security shall nevertheless be valid.

A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

The Trustee shall authenticate, on or prior to the Original Issue Date, Securities for original issue in the aggregate principal amount not to exceed $175,832,200 upon written orders of the Company in the form of an Officers’ Certificate, and shall authenticate from time to time thereafter Securities in an aggregate principal amount equal to the aggregate PIK Payment amount payable on such issue date, as specified in written orders of the Company in the form of an Officers’ Certificate. The Officers’ Certificate shall specify the amount of Securities to be authenticated, the date on which the Securities are to be authenticated and the aggregate principal amount of Securities outstanding on the date of authentication. The aggregate principal amount of Securities outstanding at any time may not exceed the sum of (x) $175,832,200, and (y) additional Securities issued from time to time after the Original Issue Date in an aggregate principal amount equal to the aggregate PIK Payment amount, except as provided in Section 2.07. Upon the written order of the Company in the form of an Officers’ Certificate, the Trustee shall authenticate Securities in substitution of Securities originally issued to reflect any name change of the Company.

The principal and interest on Securities shall be payable at the office of the Paying Agent.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Securities. Unless otherwise provided in the appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Company and Affiliates of the Company.

The Securities shall be issuable only in registered form without coupons.

SECTION 2.03. Registrar and Paying Agent.

The Company shall maintain an office or agency in the Borough of Manhattan, The City of New York, where (a) Securities may be presented or surrendered for registration of transfer or for exchange (“Registrar”), (b) Securities may be presented or surrendered for payment (“Paying Agent”) and (c) notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain

an office or agency in the Borough of Manhattan, The City of New York, for such purposes. Neither the Company nor any Affiliate of the Company shall act as Paying Agent. The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company, upon notice to the Trustee, may have one or more co-Registrars and one or more additional paying agents reasonably acceptable to the Trustee. The term “Paying Agent” includes any additional paying agent. The Company initially appoints the Trustee as Registrar and Paying Agent until such time as the Trustee has resigned or a successor has been appointed. The initial office of the Company and the Trustee for purposes of this Section 2.03 shall be State Street Bank and Trust Company, N.A., 61 Broadway, 15th Floor, New York, NY 10006.

The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee, in advance, of the name and address of any such Agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such.

SECTION 2.04. Paying Agent To Hold Assets in Trust.

The Company shall require each Paying Agent other than the Trustee to agree in writing that each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all assets held by the Paying Agent for the payment of principal of, or interest on, the Securities (whether such assets have been distributed to it by the Company or any other obligor on the Securities), and shall notify the Trustee of any Default by the Company (or any other obligor on the Securities) in making any such payment. The Company at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to distribute all assets held by it to the Trustee and to account for any assets distributed. Upon distribution to the Trustee of all assets that shall have been delivered by the Company to the Paying Agent, the Paying Agent shall have no further liability for such assets.

SECTION 2.05. Securityholder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of the Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee before each Record Date and at such other times as the Trustee may request in writing a list as of such date and in such form as the Trustee may reasonably require of the names and addresses of the Holders, which list may be conclusively relied upon by the Trustee.

SECTION 2.06. Transfer and Exchange.

When Securities in certificated form are presented to the Registrar or a co-Registrar with a request to register the transfer of such Securities or to exchange such Securities for an equal principal amount of Securities of other authorized denominations, the Registrar or co-Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that the Securities surrendered for transfer or exchange

shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar or co-Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities (and the Guarantors shall execute the Guarantees thereon) at the Registrar’s or co-Registrar’s request. No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchanges or transfers pursuant to Sections 2.02, 2.10, 3.07, 4.15, 4.16 or 9.05). The Registrar or co-Registrar shall not be required to register the transfer of or exchange of any Security (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Securities and ending at the close of business on the day of such mailing and (ii) selected for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of any Security being redeemed in part.

SECTION 2.07. Replacement Securities.

If a mutilated Security is surrendered to the Trustee or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security (and the Guarantors shall execute the Guarantees thereon) if the Trustee’s requirements are met. If required by the Trustee or the Company, such Holder must provide an indemnity bond or other indemnity, sufficient in the judgment of the Company, the Guarantors and the Trustee, to protect the Company, the Guarantors, the Trustee or any Agent from any loss which any of them may suffer if a Security is replaced. The Company may charge such Holder for its reasonable out-of-pocket expenses in replacing a Security, including reasonable fees and expenses of counsel. Every replacement Security shall constitute an additional obligation of the Company and the Guarantors.

SECTION 2.08. Outstanding Securities.

Securities outstanding at any time are all the Securities that have been authenticated by the Trustee except those cancelled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Security does not cease to be outstanding because the Company or any of its Affiliates holds the Security.

If a Security is replaced pursuant to Section 2.07 (other than a mutilated Security surrendered for replacement), it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. A mutilated Security ceases to be outstanding upon surrender of such Security and replacement thereof pursuant to Section 2.07.

If on a Redemption Date or the Maturity Date the Paying Agent holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the principal and interest due on the Securities payable on that date, then on and after that date such Securities cease to be outstanding and interest on them ceases to accrue; provided, however, that to the extent the Trustee is enjoined from making payments to the Holders, interest will continue to accrue until such time as the Trustee is not so enjoined.

SECTION 2.09. Treasury Securities.

In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or an Affiliate of the Company shall be disregarded, except that, for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities that the Trustee knows are so owned shall be disregarded.

SECTION 2.10. Temporary Securities.

Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities (and the Guarantors shall execute the guarantees thereon) upon receipt of a written order of the Company in the form of an Officers’ Certificate. The Officers’ Certificate shall specify the amount of temporary Securities to be authenticated and the date on which the temporary Securities are to be authenticated. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and the Guarantors shall execute Guarantees on, upon receipt of a written order of the Company pursuant to Section 2.02, definitive Securities in exchange for temporary Securities.

SECTION 2.11. Cancellation.

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall cancel and, at the written direction of the Company, shall dispose of all Securities surrendered for transfer, exchange, payment or cancellation. Subject to Section 2.07, the Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11.

SECTION 2.12. Defaulted Interest.

If the Company defaults in a payment of interest on the Securities, it shall, unless the Trustee fixes another record date pursuant to Section 6.10, pay the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest to the persons who are Holders on a subsequent special record date, which date shall be the fifteenth day next preceding the date fixed by the Company for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least 15 days before the subsequent special record date, the Company shall mail to each Holder, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid.

SECTION 2.13. CUSIP Number.

The Company in issuing the Securities may use a CUSIP number or numbers, and if so, the Trustee shall use the CUSIP number or numbers in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number or numbers printed in the notice or on the Securities, and that reliance may be placed only on the other identification numbers printed on the Securities.

SECTION 2.14. Designation.

The Indebtedness evidenced by the Securities and the Guarantees is hereby irrevocably designated as “senior indebtedness” or such other term denoting seniority (i) for all purposes of the provisions defining subordination contained in agreements that provide that the Indebtedness of the Company issued pursuant to such agreements is subordinate to Indebtedness designated as senior indebtedness and (ii) for the purposes of any future Indebtedness of the Company which the Company expressly makes subordinate to any senior indebtedness or such other term denoting seniority. In connection with the issuance of any such future subordinated Indebtedness, the Company shall take all necessary steps to effectuate the foregoing.

ARTICLE III.

REDEMPTION

SECTION 3.01. Optional Redemption.

(a) The Securities will be subject to redemption, in whole or in part, at the option of the Company, at any time or from time to time, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued interest to the redemption date, if redeemed during the 12 month period beginning on October 29 of the years indicated below:

Year	Percentage
2002	100	%
2003	106	%
2004	104	%
2005	102	%
2006 and thereafter	100	%

(b) In addition, Renco will have the right at any time to require that all or part of the then outstanding Securities be sold to Renco at a price equal to, at any given time, the price, including accrued interest, that the Company would have to pay to redeem such Securities at such time (the “Renco Call”).

SECTION 3.02. Notices to Trustee.

If the Company elects to redeem Securities or Renco elects to purchase Securities, in each case pursuant to this Indenture and the Securities, the Company shall notify the Trustee and the Paying Agent in writing of the Redemption Date or the Purchase Date, as the case may be, and the principal amount of the Securities to be redeemed or purchased, as the case may be, and whether it wants the Trustee to give notice of redemption or purchase, as the case may be, to the Holders (at the Company’s expense) at least 30 days (unless a shorter notice shall be satisfactory to the Trustee) but not more than 60 days before the Redemption Date or the Purchase Date, as the case may be. Any such notice may be cancelled at any time prior to notice of such redemption or such purchase, as the case may be, being mailed to any Holder and shall thereby be void and of no effect.

SECTION 3.03. Selection of Securities To Be Redeemed or Purchased.

If less than all of the Securities are to be redeemed or purchased at any time, the Trustee shall select the Securities to be redeemed or purchased, as the case may be, in compliance with the requirements of the principal national securities exchange, if any, on which the Securities being redeemed or purchased, as the case may be, are listed or, if the Securities are not listed on a national securities exchange, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate.

The Trustee shall make the selection from the Securities outstanding and not previously called for redemption or purchase, as the case may be, and shall promptly notify the Company in writing of the Securities selected for redemption or purchase, as the case may be, and, in the case of any Security selected for partial redemption or purchase, as the case may be, the principal amount thereof to be redeemed or purchased, as the case may be. Securities in denominations of $1,000 or less may be redeemed or purchased, as the case may be, only in whole. The Trustee may select for redemption or purchase, as the case may be, portions (equal to $1,000 or any integral multiple thereof) of the principal of Securities that have denominations larger than $1,000. Provisions of this Indenture that apply to Securities called for redemption or purchase, as the case may be, also apply to portions of Securities called for redemption or purchase, as the case may be.

SECTION 3.04. Notice of Redemption or Purchase.

Except as otherwise provided in Section 3.01, at least 30 days but not more than 60 days before a Redemption Date or Purchase Date, the Company shall mail a notice of redemption or purchase, as the case may be, by first class mail to each Holder whose Securities are to be redeemed or purchased, as the case may be, with a copy to the Trustee. At the Company’s request, the Trustee shall give the notice of redemption or purchase, as the case may be, in the Company’s name and at the Company’s expense. Each notice for redemption or purchase, as the case may be, shall identify the Securities to be redeemed and shall state:

(1) the Redemption Date or the Purchase Date, as the case may be;

(2) the Redemption Price or the Purchase Price, as the case may be;

(3) the name and address of the Paying Agent;

(4) that Securities called for redemption or purchase, as the case may be, must be surrendered to the Paying Agent to collect the Redemption Price or the Purchase Price, as the case may be;

(5) that, unless the Company or Renco defaults in making the redemption payment or the payment of the Purchase Price, as the case may be, interest on Securities called for redemption or purchase, as the case may be, ceases to accrue on and after the Redemption Date or the Purchase Date, as the case may be, and the only remaining right of the Holders of such Securities is to receive payment of the Redemption Price or Purchase Price, as the case may be, upon surrender to the Paying Agent of the Securities redeemed or purchased, as the case may be;

(6) if any Security is being redeemed or purchased, as the case may be, in part, the portion of the principal amount of such Security to be redeemed or purchased, as the case may be, and that, after the Redemption Date or the Purchase Date, as the case may be, and upon surrender of such Security, a new Security or Securities in the aggregate principal amount equal to the unredeemed portion or unpurchased portion, as the case may be, thereof will be issued;

(7) if fewer than all the Securities are to be redeemed or purchased, as the case may be, the identification of the particular Securities (or portion thereof) to be redeemed or purchased, as the case may be, as well as the aggregate principal amount of Securities to be redeemed or purchased, as the case may be, and the aggregate principal amount of Securities to be outstanding after such partial redemption or partial purchase, as the case may be; and

(8) the CUSIP number, if any, relating to such Securities.

SECTION 3.05. Effect of Notice of Redemption or Purchase.

Once notice of redemption or purchase is mailed in accordance with Section 3.04, Securities called for redemption or purchase, as the case may be, become due and payable on the Redemption Date and at the Redemption Price or on the Purchase Date at the Purchase Price, as the case may be. Upon surrender to the Trustee or Paying Agent, such Securities called for redemption or purchase, as the case may be, shall be paid at the Redemption Price plus accrued interest to the Redemption Date or at the Purchase Price plus accrued interest to the Purchase Date, as the case may be, but interest installments whose maturity is on or prior to such Redemption Date or such Purchase Date, as the case may be, will be payable on the relevant Interest Payment Dates to the Holders of record at the close of business on the relevant Record Dates referred to in the Securities.

SECTION 3.06. Deposit of Redemption Price or Purchase Price.

On or before the Redemption Date or the Purchase Date, as the case may be, the Company or Renco, as the case may be, shall deposit with the Paying Agent U.S. Legal Tender sufficient and timely to pay the Redemption Price or the Purchase Price, as the case may be, of

all Securities to be redeemed or purchased, as the case may be, on that date (other than Securities or portions thereof called for redemption or purchased, as the case may be, on that date which have been delivered by the Company to the Trustee for cancellation). The Paying Agent shall promptly return to the Company or Renco, as the case may be, any U.S. Legal Tender so deposited which is not required for that purpose upon the written request of the Company, except with respect to monies owed as obligations to the Trustee pursuant to Article Seven.

If the Company or Renco, as the case may be, complies with the preceding paragraph, then, unless the Company or Renco, as the case may be, defaults in the payment of such Redemption Price or Purchase Price, as the case may be, interest on the Securities to be redeemed or purchased, as the case may be, will cease to accrue on and after the applicable Redemption Date or Purchase Date, as the case may be, whether or not such Securities are presented for payment.

SECTION 3.07. Securities Redeemed or Purchased in Part.

Upon surrender of a Security that is to be redeemed or purchased in part, as the case may be, the Trustee shall authenticate for the Holder a new Security or Securities equal in principal amount to the unredeemed or unpurchased, as the case may be, portion of the Security surrendered.

ARTICLE IV.

COVENANTS

SECTION 4.01. Payment of Securities.

The Company shall pay the principal of and interest on the Securities on the dates and in the manner provided in the Securities. An installment of principal of or interest on the Securities shall be considered paid on the date it is due if the Trustee or Paying Agent holds on that date U.S. Legal Tender designated for and sufficient and timely to pay the installment. If a PIK Payment is made, the installment of interest to which such PIK Payment applies shall be considered paid on the date it is due if the Trustee or Paying Agent holds on that date duly issued and authenticated Securities in an aggregate amount equal to the PIK Payment amount. Interest on the Securities will be computed on the basis of a 360-day year composed of twelve 30-day months.

The Company shall pay interest on overdue principal and premium, if any, and interest on overdue installments of interest, to the extent lawful, at a rate per annum equal to the rate of interest applicable to the Securities plus 2%.

SECTION 4.02. Maintenance of Office or Agency.

The Company shall maintain in the Borough of Manhattan, The City of New York, the office or agency required under Section 2.03. The Company shall give prior notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the

Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 12.02.

The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Company hereby initially designates the office of State Street Bank and Trust Company, Goodwin Square, 225 Asylum, 23rd Floor, Hartford, CT 06103, as such office of the Company in accordance with this Section 4.02.

SECTION 4.03. Limitation on Restricted Payments.

The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, after the Issue Date (a) declare or pay any dividend or make any distribution on the Company’s Capital Stock or make any payment to holders of such Capital Stock as such (other than dividends or distributions payable in Qualified Capital Stock of the Company) (provided, however, that the foregoing limitation shall not preclude the payment of dividends to the Company by any of its Subsidiaries or the payment of dividends to any Subsidiary by any other Subsidiary), (b) purchase, redeem or otherwise acquire or retire for value any Capital Stock of the Company or any warrants, rights or options to purchase or acquire shares of any class of such Capital Stock, (c) purchase, redeem, prepay, defease or otherwise acquire or retire for value, prior to any scheduled maturity, scheduled repayment or scheduled sinking fund payment, Indebtedness of the Company or any of the Guarantors that is expressly subordinate in right of payment to the Securities or the Guarantee of such Guarantor, as the case may be, or (d) make any Investment (excluding any Permitted Investment) (each of the foregoing actions set forth in clauses (a), (b), (c) and (d) being referred to as a “Restricted Payment”), if at the time of such Restricted Payment or immediately after giving effect thereto,(i) a Default or an Event of Default shall have occurred and be continuing or (ii) Restricted Payments made subsequent to the Issue Date (the amount expended for such purposes, if other than in cash, shall be the Fair Market Value of such property proposed to be transferred by the Company or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment) shall exceed the sum of:

(w) 50% of the difference of (x) cumulative Consolidated Net Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of such loss) of the Company) earned subsequent to the Issue Date and prior to the date the Restricted Payment occurs (treating such period as a single accounting period) minus (y) any tax distributions made pursuant to clause (7) of the second paragraph of this section;

(x) 100% of the aggregate net proceeds, including the Fair Market Value of Property other than cash, received by the Company from any person (other than a Subsidiary of the Company) from the issuance and sale subsequent to the Issue

Date of Qualified Capital Stock of the Company (excluding (A) Qualified Capital Stock paid as a dividend on any Capital Stock or as interest on any Indebtedness, and (B) any net proceeds from issuances and sales financed directly or indirectly using funds borrowed from the Company or any Subsidiary of the Company, until and to the extent such borrowing is repaid);

(y) 100% of the aggregate net proceeds, including the Fair Market Value of property other than cash, received by the Company from any person (other than a Subsidiary of the Company) from the issuance and sale of Disqualified Capital Stock and/or Indebtedness, in each case that has been converted into or exchanged for Qualified Capital Stock of the Company after the Issue Date; and

(z) without duplication, the sum of (1) the aggregate amount returned in cash on or with respect to Investments (other than Permitted Investments) made subsequent to the Issue Date whether through interest payments, principal payments, dividends or other distributions or payments, (2) the net cash proceeds received by the Company or any Restricted Subsidiary from the disposition of all or any portion of such Investments (other than to a Subsidiary of the Company) and (3) upon redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, the Fair Market Value of such Subsidiary; provided, however, that the sum of clauses (1), (2) and (3) above shall not exceed the aggregate amount of all such Investments made subsequent to the Issue Date.

The foregoing provisions shall not prohibit:

(1) the payment of any dividend within 60 days after the date of its declaration if the dividend would have been permitted on the date of declaration;

(2) the acquisition of Capital Stock of the Company or Indebtedness of the Company or any Guarantor either (i) solely in exchange for shares of Qualified Capital Stock of the Company or (ii) through the application of net proceeds of a substantially concurrent sale for cash (other than to a Subsidiary of the Company) of shares of Qualified Capital Stock of the Company;

SECTION 4.09. SEC Reports and Other Information.

(a) At all times when the Company is required or permitted voluntarily to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act or this Indenture is qualified under the TIA, the Company (at its own expense) shall file with the SEC and shall file with the Trustee and mail or cause the Trustee to mail to the Holders at their addresses set forth in the register of Securities within 15 days after it files them with the SEC copies of the annual reports, quarterly reports and the information, documents, and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) to be filed pursuant to Section 13 or 15(d) of the Exchange Act. If the Company is not subject to the requirements of such Section 13 or 15(d) of the Exchange Act and not permitted to voluntarily file and this Indenture has not been qualified under the TIA, the Company (at its own expense) shall file with the Trustee and mail or cause the Trustee to mail to the Holders at their addresses set forth in the register of Securities, within 15 days after it would have been required to file such information with the SEC, all information and financial statements, including any notes thereto and with respect to annual reports, quarterly reports, an auditors’ report by an accounting firm of established national reputation, and a “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” both comparable to the disclosure that each of the Company would have been required to include in such annual reports, quarterly reports, information, documents or other reports, as if the Company was subject to the requirements of such Section 13 or 15(d) of the Exchange Act, in each case in the form that would have been required by the SEC. Upon qualification of this Indenture under the TIA, the Company shall also comply with the provisions of TIA Section 314(a).

At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder of a Series A Note, the Company will promptly furnish or cause to be furnished such information as is specified pursuant to Rule 144A(d)(4) under the Securities

SECTION 4.10. Waiver of Stay, Extension or Usury Laws.

Each of the Company and the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the each of Company and the Guarantors from paying all or any portion of the principal of or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) each of the Company and the Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

(b) The foregoing provisions shall not apply to (i) any Restricted Payment that is made in compliance with Section 4.03, (ii) payments by the Company or any of the Restricted Subsidiaries to Renco or DRA of the amounts set forth in clauses (4), (5), (7) and (8) of the second paragraph of Section 4.03 and (iii) reasonable and customary regular fees to directors of the Company and the Restricted Subsidiaries who are not

(b) The Company and the Guarantors shall not, directly or indirectly, in any event incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinated to the Securities or the Guarantee of such Guarantor, as the case may be, to the same extent and in the same manner as such Indebtedness is subordinated to such other Indebtedness of the Company or such Guarantor.

SECTION 4.13. Limitation on Dividends and Other Payment Restrictions Affecting Restricted Subsidiaries.

The Company will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to: (a) pay dividends or make any other distributions on its Capital Stock, or any other interest or participation in, or measured by, its profits, owned by the Company or by any Restricted Subsidiary, or pay any Indebtedness owed to the Company or any Restricted Subsidiary; (b) make loans or advances to the Company or any Restricted Subsidiary; or (c) transfer any of its properties or assets to the Company or to any Restricted Subsidiary, except, in each case, for such encumbrances or restrictions existing under or by reason of: (i) applicable law; (ii) this Indenture; (iii) customary non-assignment provisions of any lease governing a leasehold interest of the Company or any Restricted Subsidiary; (iv) any instrument governing Indebtedness of a person acquired by the Company or any Restricted Subsidiary at the time of such acquisition, which encumbrance or restriction is not applicable to any person, or the properties or assets of any person, other than the person or its Subsidiaries so acquired; (v) any written agreement existing on the Issue Date or amendments or modifications thereto, provided that no such agreement shall be modified or amended in such a manner as to make the encumbrance or restriction more restrictive than as in effect on the Issue Date, except that International Sales Agency Services Contract and the Hedging Services Contract between

Doe Run Peru and the Company now in effect, by which Doe Run Peru pays certain fees to the Company, may be amended to reduce the aggregate amount payable thereunder to the Company to an amount equal to no less than $4,000,000 per annum; (vi) Indebtedness under the U.S. Revolving Credit Facility, the Senior Credit Facility and any other Indebtedness existing and as in effect on the Issue Date and any refinancing, refunding, replacement or extensions thereof, provided that any such encumbrance or restriction contained in any refinancing, refunding, replacement or extension of the U.S. Revolving Credit Facility shall be no more restrictive than such encumbrance or restriction contained in the U.S. Revolving Credit Facility as in effect on the Issue Date; (vii) Indebtedness under the Peruvian Revolving Credit Facility or any refinancings, refundings, replacements or extensions thereof; and (viii) Indebtedness incurred in accordance with this Indenture, provided that such encumbrance or restriction shall be no more restrictive than any encumbrance or restriction contained in the Revolving Credit Facilities.

if at any time any non-cash consideration received by the Company or any such Restricted Subsidiary, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash, then such conversion or disposition shall be deemed to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall be applied in accordance with this Section 4.16; and provided, further, that the Company may defer the Asset Sale Offer until there is an aggregate unutilized Available Amount equal to or in excess of $5 million resulting from one or more Asset Sales (at which time, the entire unutilized Available Amount, and not just the amount in excess of $5 million, shall be applied as required pursuant to this paragraph).

The Paying Agent shall promptly mail or deliver to Holders of Securities so accepted payment in an amount equal to the purchase price, and the Trustee shall promptly authenticate and mail or deliver to such Holders new Securities equal in principal amount to any unpurchased portion of the Securities surrendered.

ARTICLE VI.

DEFAULT AND REMEDIES

(2) the Company defaults in the payment of the stated principal amount of any Securities when the same becomes due and payable at maturity, upon acceleration or redemption pursuant to an offer to purchase required hereunder or otherwise;

(3) the Company or any of the Guarantors fails to comply in all material respects with any of their other agreements contained in the Securities or this Indenture (including, without limitation, under Sections 4.15, 4.16 and 5.01) and the Default continues for the period and after the notice specified below;

(4) there shall be any default or defaults in the payment of principal or interest under one or more agreements, instruments, mortgages, bonds, debentures or other evidences of Indebtedness under which the Company or any Restricted Subsidiary then has outstanding Indebtedness in excess of $10.0 million, individually or in the aggregate;

(5) there shall be any default or defaults under one or more agreements, instruments, mortgages, bonds, debentures or other evidences of Indebtedness under which the Company or any Restricted Subsidiary then has outstanding Indebtedness in excess of $7.5 million, individually or in the aggregate, and such default or defaults have resulted in the acceleration of the maturity of such Indebtedness;

(6) the Company or any Restricted Subsidiary fails to perform (after giving effect to any applicable grace periods) any term, covenant, condition or provision of one or more agreements, instruments, mortgages, bonds, debentures or other evidences of Indebtedness under which the Company or any Restricted Subsidiary then has outstanding Indebtedness in excess of $7.5 million, individually or in the aggregate, and such failure to perform results in the commencement of judicial proceedings to foreclose upon any assets of the Company or any such Restricted Subsidiary securing such Indebtedness or the holders of such Indebtedness shall have exercised any right under applicable law or applicable security documents to take ownership of any such assets in lieu of foreclosure;

(7) one or more judgments, orders or decrees for the payment of money which either individually or in the aggregate at any one time exceed $7.5 million shall be rendered against the Company or any Restricted Subsidiary by a court of competent jurisdiction and shall remain undischarged and unbonded for a period (during which execution shall not be effectively stayed) of 60 consecutive days after such judgment becomes final and nonappealable;

(8) the Company or any Significant Subsidiary (a) admits in writing its inability to pay its debts generally as they become due, (b) commences a voluntary case or proceeding under any Bankruptcy Law with respect to itself, (c) consents to the entry of a judgment, decree or order for relief against it in an involuntary case or proceeding under any Bankruptcy Law, (d) consents to the appointment of a Custodian of it or for substantially all of its property, (e) consents to or acquiesces in the institution of a bankruptcy or an insolvency proceeding against it, (f) makes a general assignment for the benefit of its creditors or (g) takes any corporate action to authorize or effect any of the foregoing;

(9) a court of competent jurisdiction enters a judgment, decree or order for relief in respect of the Company or any Significant Subsidiary in an involuntary case or proceeding under any Bankruptcy Law which shall (1) approve as properly filed a petition seeking reorganization, arrangement, adjustment or composition in respect of the Company or any Significant Subsidiary, (2) appoint a Custodian of the Company or any Significant Subsidiary or for substantially all of its property or (3) order the winding-up or liquidation of its affairs, and such judgment, decree or order shall remain unstayed and in effect for a period of 60 consecutive days;

(10) any of the Guarantees of any Significant Subsidiary ceases to be in full force and effect or any of such Guarantees is declared to be null and void and unenforceable or any of such Guarantees is found to be invalid, or any such Guarantor denies its liability under its Guarantee (other than by reason of release of a Guarantor in accordance with the terms of this Indenture); or

(11) any Collateral Document after the date of its effectiveness ceases to be in full force and effect or any Collateral Document ceases to give the Trustee the Liens, rights, powers and privileges purported to be created thereby in any material respect.

A Default under clause (3) above (other than in the case of any Default under Sections 4.15, 4.16 and 5.01, which Defaults shall be Events of Default without the notice and without the passage of time specified in this paragraph) is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company and the Trustee, of the Default, and the Company does not cure the Default within 30 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.” Such notice shall be given by the Trustee if so requested by the Holders of at least 25% in principal amount of the Securities then outstanding.

SECTION 6.02. Acceleration.

If an Event of Default (other than an Event of Default specified in Section 6.01(8) or 6.01(9)) occurs and is continuing, then and in every such case the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by written notice to the Company and the Trustee, and the Trustee shall, upon the request of such Holders, declare the aggregate unpaid principal of and premium, if any, on all of the Securities outstanding, together with accrued but unpaid interest thereon to the date of payment, to be due and payable and, upon any such declaration, the same shall become and be due and payable; provided, however, that the Trustee shall be under no obligation to follow any request of any of the Holders unless such Holders shall have offered to the Trustee, after request by the Trustee, reasonable security or indemnity against the costs, expenses and liabilities which may be incurred by it in compliance with such request, order or direction. If an Event of Default specified in Section 6.01(8) or 6.01(9) occurs, all unpaid principal, premium, if any, and accrued interest on the Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholder. Subject to all provisions of this Indenture and applicable law, the Holders of a majority in aggregate principal amount of the then outstanding Securities have the right to direct the time,

method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. The Trustee may withhold from Holders notice of any continuing Default or Event of Default (except a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Securities or that resulted from the failure to comply with the provisions of Section 6.01(8) or 6.01(9), if it determines that withholding notice is in their interest. The Holders of a majority in principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (i) all existing Events of Default, other than the non-payment of the principal of, and any premium if any, and interest on the Securities which have become due solely by such declaration of acceleration, have been cured or waived and the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. No such rescission shall affect any subsequent default or impair any right consequent thereto. In the event that a declaration of acceleration under either Section 6.01(4) or 6.01(5) above has occurred and is continuing, such declaration of acceleration shall be automatically annulled if the Indebtedness that is the subject of such Event of Default has been discharged or paid (or the default thereunder otherwise cured) or the holders of such Indebtedness shall have rescinded their declaration of acceleration in respect of such Indebtedness within 60 days thereafter and no other Event of Default has occurred during such 60-day period which has not been cured or waived.

SECTION 6.03. Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

SECTION 6.04. Waiver of Past Defaults.

Subject to Sections 6.07 and 9.02, the Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except a Default in the payment of principal of, premium, if any, or interest on any Security as specified in clauses (1) and (2) of Section 6.01 or in respect of any provision hereof which cannot be modified or amended without the consent of the Holder so affected pursuant to Section 9.02. When a Default or Event of Default is so waived, it shall be deemed cured and cease to exist.

SECTION 6.05. Control by Majority.

The Holders of a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it including, without limitation, any remedies

provided for in Section 6.03. Subject to Section 7.01, however, the Trustee may refuse to follow any direction that conflicts with any law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Securityholder, or that may involve the Trustee in personal liability; provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

SECTION 6.06. Limitation on Suits.

A Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless:

(1) the Holder gives to the Trustee notice of a continuing Event of Default;

(2) Holders of at least 25% in principal amount of the outstanding Securities make a written request to the Trustee to pursue the remedy;

(3) such Holders offer to the Trustee reasonable indemnity against any loss, liability or expense to be incurred in compliance with such request;

(4) the Trustee does not comply with the request within 30 days after receipt of the request and the offer of satisfactory indemnity; and

(5) during such 30-day period the Holders of a majority in principal amount of the outstanding Securities do not give the Trustee a direction which, in the opinion of the Trustee, is inconsistent with the request.

A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over such other Securityholder.

SECTION 6.07. Rights of Holders To Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on a Security, on or after the respective due dates expressed in such Security, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

SECTION 6.08. Collection Suit by Trustee.

If an Event of Default in payment of principal or interest specified in clause (1) or (2) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company, the Guarantors or any other obligor on the Securities for the whole amount of principal and accrued interest remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per annum borne by the Securities and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09. Trustee May File Proofs of Claim.

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, taxes, disbursements and advances of the Trustee, its agents and counsel) and the Securityholders allowed in any judicial proceedings relating to the Company, the Guarantors or any other obligor upon the Securities, any of their respective creditors or any of their respective property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings is hereby authorized by each Securityholder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Securityholders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, taxes, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due the Trustee under Section 7.07. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Securityholder in any such proceeding.

SECTION 6.10. Priorities.

If the Trustee collects any money pursuant to this Article Six, it shall pay out the money in the following order:

First: to the Trustee for amounts due under Section 7.07 and then to the Collateral Agent for amounts due under the Collateral Documents;

Second: to Holders for interest accrued on the Securities, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for interest;

Third: to Holders for principal amounts owing under the Securities and other amounts owing to the Holders with respect to the Securities, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and other amounts owing to the Holders with respect to the Securities; and

Fourth: to the Company or any other obligor on the Securities, as their interests may appear, or as a court of competent jurisdiction may direct.

The Trustee, upon prior notice to the Company, may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10.

SECTION 6.11. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees,

against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than 10% in principal amount of the outstanding Securities.

SECTION 6.12. Ranking.

Every Holder, by accepting a Security, shall be deemed to agree that the Indebtedness of Doe Run Peru and its Subsidiaries evidenced by their respective Guarantees are hereby contractually subordinated to the prior payment in full of all obligations under the Peruvian Revolving Credit Facility, including, but not limited to all principal, interest, fees, however denominated, any other amounts owed under the Peruvian Revolving Credit Facility, and specifically including all of the foregoing whether arising or accruing before or after the commencement of any insolvency proceedings. No further documentation or agreement is necessary to effectuate the foregoing subordination. Upon the written request of BCP (or any other agent under the Peruvian Revolving Credit Facility), however, the Trustee is authorized to take any and all actions and execute any necessary documentation, whether on the Issue Date or at any time thereafter, to confirm or effectuate the foregoing subordination. In addition, except as described above, each of the Company and its Subsidiaries agrees that the Indebtedness of Doe Run Peru and its Subsidiaries evidenced by their respective Guarantees will rank senior in right of payment to all future unsecured indebtedness of Doe Run Peru, subject to statutorily preferred exceptions and statutorily mandated priorities based on the date of issuance with respect to payment of obligations under applicable Peruvian law.

SECTION 7.03. Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company, any Subsidiary of the Company or their respective Affiliates with the same rights it would have if it were not Trustee.

Except in the case of a Default or an Event of Default in payment of principal of, or interest on, any Security, and a Default that resulted from the failure to comply with Sections 4.15, 4.16 or 5.01, the Trustee may withhold the notice if and so long as its board of directors, the executive committee of its board of directors or a committee of its directors and/or Trust Officers in good faith determines that withholding the notice is in the interest of the Securityholders.

After such delivery or irrevocable deposit the Trustee upon request shall acknowledge in writing the discharge of the Company’s obligations under the Securities, the Guarantees and this Indenture except for those surviving obligations specified above.

SECTION 8.02. Legal Defeasance and Covenant Defeasance.

(a) The Company may, at its option by Board Resolution, at any time, with respect to the Securities, elect to have either paragraph (b) or paragraph (c) below be applied to the outstanding Securities upon compliance with the conditions set forth in paragraph (d).

(b) Upon the Company’s exercise under paragraph (a) of the option applicable to this paragraph (b), the Company shall be deemed to have been released and discharged from its obligations with respect to the outstanding Securities and the Guarantees on the date the conditions set forth below are satisfied (hereinafter, “legal defeasance”). For this purpose, such legal defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding Securities, which shall thereafter be deemed to be “outstanding” only for the purposes of paragraph (e) below and the other Sections of and matters under this Indenture referred to in (i) and (ii) below, and to have satisfied all its other obligations under such Securities and Guarantees and this Indenture insofar as such Securities and Guarantees are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Securities to receive solely

from the trust fund described in paragraph (d) below and as more fully set forth in such paragraph, payments in respect of the principal of and interest on such Securities and Guarantees when such payments are due, (ii) the Company’s obligations with respect to such Securities and Guarantees under Sections 2.05, 2.06, 2.07, 2.08, 4.02, 7.07, 7.08, 8.04 and 8.05, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 8.02.

For this purpose, such covenant defeasance means that, with respect to the outstanding Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby.

(d) The following shall be the conditions to application of either paragraph (b) or paragraph (c) above to the outstanding Securities:

(i) the Company shall irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal of and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge principal of, premium, if any, and interest on the outstanding Securities on the Maturity Date of such principal or installment of principal or interest in accordance with the terms of this Indenture and of such Securities; provided, however, that the Trustee (or other qualifying trustee) shall have received an irrevocable written order from the Company instructing the Trustee (or other qualifying trustee) to apply such

money or the proceeds of such U.S. Government Obligations to said payments with respect to the Securities;

(ii) no Default or Event of Default or event which with notice or lapse of time or both would become a Default or an Event of Default with respect to the Securities shall have occurred and be continuing on the date of such deposit or, insofar as Sections 6.01(8) and (9) are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period);

(iii) such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a Default or Event of Default under, this Indenture or any other agreement or instrument to which the Company is a party or by which it is bound;

(iv) in the case of an election under paragraph (b) above, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (x) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (y) since the date of this Indenture, there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such legal defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred;

(v) in the case of an election under paragraph (c) above, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred;

(vi) in the case of an election under either paragraph (b) or (c) above, an Opinion of Counsel to the effect that, assuming no intervening bankruptcy of the Company between the date of deposit and the 91st day following the date of deposit and that no Holder is an insider of the Company, (x) the trust funds will not be subject to any rights of any other holders of Indebtedness of the Company, and (y) after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable Bankruptcy Law; provided, however, that if a court were to rule under any such law in any case or proceeding that the trust funds remained property of the Company, no opinion needs to be given as to the effect of such laws on the trust funds except the following: (A) assuming such trust funds remained in the Trustee’s possession prior to such court ruling to the extent not paid to Holders of Securities, the Trustee will hold, for the benefit of the Holders of Securities, a valid and enforceable security interest in such trust funds that is not avoidable in bankruptcy or otherwise, subject only to principles of equitable subordination, (B) the Holders of Securities will be entitled to receive

adequate protection of their interests in such trust funds if such trust funds are used, and (C) no property, rights in property or other interests granted to the Trustee or the Holders of Securities in exchange for or with respect to any of such funds will be subject to any prior rights of any other person, subject only to prior Liens granted under Section 364 of Title 11 of the U.S. Bankruptcy Code (or any section of any other Bankruptcy Law having the same effect), but still subject to the foregoing clause (B); and

(vii) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that (A) all conditions precedent provided for relating to either the legal defeasance under paragraph (b) above or the covenant defeasance under paragraph (c) above, as the case may be, have been complied with and (B) if any other Indebtedness of the Company shall then be outstanding, such legal defeasance or covenant defeasance will not violate the provisions of the agreements or instruments evidencing such Indebtedness.

Notwithstanding the foregoing, the Opinion of Counsel and a ruling from the Internal Revenue Service required by clause (iv) above of this Section 8.02 need not be delivered if all Securities not theretofore delivered to the Trustee for cancellation (i) have become due and payable, (ii) will become due and payable on the Maturity Date within one year or (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

(e) All money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this paragraph (e), the “Trustee”) pursuant to paragraph (d) above in respect of the outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (other than the Company or any of its Affiliates) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal and interest, but such money need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to paragraph (d) above or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Securities.

Anything in this Section 8.02 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request, in writing, by the Company any money or U.S. Government Obligations held by it as provided in paragraph (d) above which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent legal defeasance or covenant defeasance.

SECTION 8.03. Application of Trust Money.

The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to Sections 8.01 and 8.02, and shall apply the deposited money and the money from U.S. Government Obligations in accordance with this Indenture to the payment of principal of, premium, if any, and interest on the Securities.

SECTION 8.04. Repayment to Company.

Subject to Sections 7.07, 8.01 and 8.02, the Trustee shall promptly pay to the Company, upon receipt by the Trustee of an Officers’ Certificate, any excess money, determined in accordance with Sections 8.02(d)(i) and (e), held by it at any time. The Trustee and the Paying Agent shall pay to the Company upon receipt by the Trustee or the Paying Agent, as the case may be, of an Officers’ Certificate, any money held by it for the payment of principal or interest that remains unclaimed for two years; provided, however, that the Trustee and the Paying Agent before being required to make any payment may, but need not, at the expense of the Company, cause to be published once in a newspaper of general circulation in The City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein, which shall be at least 30 days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Securityholders entitled to money must look solely to the Company for payment as general creditors unless an applicable abandoned property law designates another person, and all liability of the Trustee or Paying Agent with respect to such money shall thereupon cease.

SECTION 8.05. Reinstatement.

If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Indenture by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then and only then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had been made pursuant to this Indenture until such time as the Trustee is permitted to apply all such money or U.S. Government Obligations in accordance with this Indenture; provided, however, that if the Company has made any payment of interest on or principal of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

ARTICLE IX.

AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 9.01. Without Consent of Holders.

From time to time, the Company and the Guarantors when authorized by Board Resolutions, and the Trustee, together, may amend or supplement this Indenture or the Securities without notice to or consent of any Securityholder:

(1) to cure any ambiguity, defect or inconsistency; provided that such amendment or supplement does not adversely affect the rights of any Holder;

(2) to comply with Article Five;

(3) to provide for uncertificated Securities in addition to or in place of certificated Securities;

(4) to make any other change that does not materially adversely affect the rights of any Securityholders hereunder, including, without limitation, adding Restricted Subsidiaries as additional Guarantors; or

(5) to comply with any requirements of the SEC in connection with the qualification of this Indenture under the TIA;

provided that the Company has delivered to the Trustee an Opinion of Counsel and an Officers’ Certificate, each stating that such amendment or supplement complies with the provisions of this Section 9.01.

SECTION 9.02. With Consent of Holders.

Subject to Section 6.07, the Company and the Guarantors, when authorized by Board Resolutions, and the Trustee, together, with the written consent of the Holder or Holders of at least a majority in aggregate principal amount of the outstanding Securities, may amend or supplement this Indenture or the Securities, without notice to any other Securityholders. Subject to Section 6.07, the Holder or Holders of a majority in aggregate principal amount of the outstanding Securities may waive compliance by the Company with any provision of this Indenture or the Securities without notice to any other Securityholder. However, without the consent of each Securityholder, no amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may:

(1) reduce the principal amount of Securities whose Holders must consent to an amendment, supplement or waiver of any provision of this Indenture or the Securities;

(2) reduce the rate of, or extend the time for payment of, interest, including defaulted interest, on any Security;

(3) reduce the principal amount of any Security or any premium thereon;

(4) change the Maturity Date of any Security, or alter the redemption provisions or the repurchase provisions in this Indenture or the Securities in a manner adverse to any Holder;

(5) waive a default in the payment of the principal of, interest on, or redemption payment or repurchase payment required hereunder with respect to, any Security, including without limitation, a failure to make payment when required upon a Change of Control or after an Asset Sale;

(6) make any changes in any provisions relating to waivers of defaults, the ability of the Holders to enforce their rights under this Indenture, the Securities or this Section 9.02;

(7) make the principal of, or the interest on any Security payable in money other than as provided for in this Indenture and the Securities as in effect on the date hereof;

(8) affect the ranking of the Securities or the Guarantees in a manner adverse to the Holders;

(9) after the Company’s obligation to purchase the Securities arises thereunder, amend, change or modify in any material respect any obligation of the Company to make and consummate a Change of Control Offer in the event of a Change of Control or make and consummate an Asset Sale Offer in the event of an Asset Sale or waive any default in the performance thereof or modify any of the provisions or definitions with respect to such offers;

(11) directly or indirectly release any Lien on the Collateral except in compliance with the terms of this Indenture, the Securities and the Collateral Documents.

It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

SECTION 9.03. Compliance with TIA.

From the date on which this Indenture is qualified under the TIA, every amendment, waiver or supplement of this Indenture or the Securities shall comply with the TIA as then in effect.

SECTION 9.04. Revocation and Effect of Consents.

Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to his Security or portion of his Security by notice to the Trustee or the Company received before the date on which the Trustee receives an Officers’ Certificate

certifying that the Holders of the requisite principal amount of Securities have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. Notwithstanding the above, nothing in this paragraph shall impair the right of any Securityholder under Section 316(b) of the TIA.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those persons who were Holders at such record date (or their duly designated proxies), and only those persons, shall be entitled to revoke any consent previously given, whether or not such persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date.

After an amendment, supplement or waiver becomes effective, it shall bind every Securityholder, unless it makes a change described in any of clauses (1) through (10) of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security.

SECTION 9.05. Notation on or Exchange of Securities.

If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security (and the Guarantors shall execute the Guarantees thereon) that reflects the changed terms. Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.06. Trustee To Sign Amendments, Etc.

The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article Nine; provided that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee’s own rights, duties or immunities under this Indenture. The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article Nine is authorized or permitted by this Indenture.

(ii) a policy of title insurance (or a commitment to issue title insurance) insuring that the Lien of this Indenture and any Mortgage constitutes a direct and valid and perfected mortgage Lien of the priority contemplated in Section 10.01(a) on such Real Property in an aggregate amount equal to the fair value of the Real Property, together with an Officers’ Certificate stating that any specific exceptions to such title insurance are Permitted Liens, together with such endorsements and other opinions as are contemplated by Section 10.02;

(e) All documentation required under TIA Section 314(d); and

Upon compliance with the foregoing provisions of this Section 11.04, the Trustee shall apply the Released Trust Moneys as directed and specified by the Company.

SECTION 11.05. Powers Exercisable Notwithstanding Default or Event of Default.

In case a Default or an Event of Default shall have occurred and shall be continuing, the Company, while in possession of the Collateral (other than cash, Cash Equivalents, securities and

other personal property held by, or required to be deposited or pledged with, the Trustee hereunder or under the Collateral Documents), may do any of the things enumerated in Sections 11.02, 11.03 and 11.04 if the Holders of a majority in aggregate principal amount of the Securities outstanding, by appropriate action of such Holders, shall consent to such action, in which event any certificate filed under any of such Sections shall omit the statement to the effect that no Default or Event of Default has occurred and is continuing. This Section 11.05 shall not apply, however, during the continuance of an Event of Default of the type specified in Section 6.01(1) or (2).

SECTION 11.06. Powers Exercisable by Trustee or Receiver.

If the Trustee shall be in possession of any of the Collateral hereunder or under any of the Collateral Documents, such powers may be exercised by the Trustee, in its discretion.

SECTION 11.07. Investment of Trust Moneys.

All or any part of any Trust Moneys held by the Trustee shall from time to time be invested or reinvested by the Trustee in any Cash Equivalents pursuant to the written direction of the Company, which shall specify the Cash Equivalents in which such Trust Moneys shall be invested and the maturity date of such investment. Unless an Event of Default occurs and is continuing, any interest on such Cash Equivalents (in excess of any accrued interest paid at the time of purchase) that may be received by the Trustee shall be forthwith paid to the Company. Such Cash Equivalents shall be held by the Trustee as a part of the Collateral, subject to the same provisions hereof as the cash used by it to purchase such Cash Equivalents.

The Trustee shall not be liable or responsible for any loss resulting from such investments or sales except only for its own grossly negligent action, its own grossly negligent failure to act or its own willful misconduct in complying with this Section 11.07.

ARTICLE XIII.

GUARANTEE OF SECURITIES

SECTION 13.01. Unconditional Guarantee.

Subject to the provisions of this Article Thirteen and to Section 6.12, each of the Guarantors hereby, jointly and severally, unconditionally and irrevocably guarantees, on a senior basis, except as described in Section 6.12 (such guarantee to be referred to herein as a “Guarantee”), to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Securities or the obligations of the Company or any other Guarantors to the Holders or the Trustee hereunder or thereunder, that: (a) the principal of, premium, if any, and interest on the Securities shall be duly and punctually paid in full when due, whether at maturity, upon redemption at the option of Holders pursuant to the provisions of the Securities relating thereto, by acceleration or otherwise, and interest on the overdue principal and (to the extent permitted by law) interest, if any, on the Securities and all other obligations of the Company or the Guarantors to the Holders or the Trustee hereunder or thereunder (including amounts due the Trustee under Section 7.07 hereof) and all other obligations shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Securities or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed, or failing performance of any other obligation of the Company to the Holders under this Indenture or under the Securities, for whatever reason, each Guarantor shall be obligated to pay, or to perform or cause the performance of, the same immediately. An Event of Default under this Indenture or the Securities shall constitute an event of default under this Guarantee, and shall entitle the Holders of Securities to accelerate the obligations of the Guarantors hereunder in the same manner and to the same extent as the obligations of the Company.

Each of the Guarantors hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Securities with respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same, whether or not a Guarantee is affixed to any particular Security, or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each of the Guarantors hereby waives the benefit of diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and

covenants that its Guarantee shall not be discharged except by complete performance of the obligations contained in the Securities, this Indenture and this Guarantee. This Guarantee is a guarantee of payment and not of collection. If any Holder or the Trustee is required by any court or otherwise to return to the Company or to any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or such Guarantor, any amount paid by the Company or such Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between it, on the one hand, and the Holders of Securities and the Trustee, on the other hand, (a) subject to this Article Eleven, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (b) in the event of any acceleration of such obligations as provided in Article Six hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Guarantee.

No stockholder, officer, director, employee or incorporator, past, present or future, or any Guarantor, as such, shall have any personal liability under this Guarantee by reason of his, her or its status as such stockholder, officer, director, employee or incorporator.

Each Guarantor that makes a payment or distribution under its Guarantee shall be entitled to a contribution from each other Guarantor in an amount pro rata based on the net assets of each Guarantor, determined in accordance with GAAP.

SECTION 13.02. Limitations on Guarantees.

The obligations of each Guarantor under its Guarantee are limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under this Indenture, will result in the obligations of such Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under any laws of the United States, any state of the United States, the District of Columbia, the Republic of Peru or the Cayman Islands or any political subdivisions or territories therein or any other jurisdiction under which a Guarantor is organized.

SECTION 13.03. Execution and Delivery of Guarantee.

To further evidence the Guarantee set forth in Section 13.01, each Guarantor hereby agrees that a notation of such Guarantee, substantially in the form of Exhibit B herein, shall be endorsed on each Security authenticated and delivered by the Trustee. Such Guarantee shall be executed on behalf of each Guarantor by either manual or facsimile signature of two Officers of each Guarantor, each of whom, in each case, shall have been duly authorized to so execute by all requisite corporate action. The validity and enforceability of any Guarantee shall not be affected by the fact that it is not affixed to any particular Security.

Each of the Guarantors hereby agrees that its Guarantee set forth in Section 13.01 shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Guarantee.

If an Officer of a Guarantor whose signature is on this Indenture or a Guarantee no longer holds that office at the time the Trustee authenticates the Security on which such Guarantee is endorsed or at any time thereafter, such Guarantor’s Guarantee of such Security shall be valid nevertheless.

The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in this Indenture on behalf of each Guarantor.

SECTION 13.04. Release of a Guarantor.

(a) If no Default exists or would exist under this Indenture, upon the sale or disposition of all of the Capital Stock of a Guarantor by the Company, in a transaction constituting an Asset Sale the Net Cash Proceeds of which are applied in accordance with Section 4.16, or upon the consolidation or merger of a Guarantor with or into any person in compliance with Article Five (in each case, other than to the Company or an Affiliate of the Company), or if any Guarantor is dissolved or liquidated in accordance with this Indenture, such Guarantor’s Guarantee shall be released, and such Guarantor and each Subsidiary of such Guarantor that is also a Guarantor shall be deemed released from all obligations under this Article Eleven without any further action required on the part of the Trustee or any Holder. Any Guarantor not so released or the entity surviving such Guarantor, as applicable, shall remain or be liable under its Guarantee as provided in this Article Eleven.

(b) The Trustee shall deliver an appropriate instrument evidencing the release of a Guarantor upon receipt of a request by the Company or such Guarantor accompanied by an Officers’ Certificate and an Opinion of Counsel certifying as to the compliance with this Section 13.04, provided the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers Certificates of the Company.

The Trustee shall execute any documents reasonably requested by the Company or a Guarantor in order to evidence the release of such Guarantor from its obligations under its Guarantee endorsed on the Securities and under this Article Eleven.

Except as set forth in Articles Four and Five and this Section 13.04, nothing contained in this Indenture or in any of the Securities shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

SECTION 13.05. Waiver of Subrogation.

Until this Indenture is discharged and all of the Securities are discharged and paid in full, each Guarantor hereby irrevocably waives and agrees not to exercise any claim or other rights

which it may now or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of the Company’s obligations under the Securities or this Indenture and such Guarantor’s obligations under this Guarantee and this Indenture, in any such instance including, without limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim or remedy of the Holders against the Company, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Company, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and any amounts owing to the Trustee or the Holders of Securities under the Securities, this Indenture, or any other document or instrument delivered under or in connection with such agreements or instruments, shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Trustee or the Holders and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be credited and applied to the obligations in favor of the Trustee or the Holders, as the case may be, whether matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 13.05 is knowingly made in contemplation of such benefits.

SECTION 13.06. Immediate Payment.

Each Guarantor agrees to make immediate payment to the Trustee on behalf of the Holders of all Obligations owing or payable to the respective Holders upon receipt of a demand for payment therefor by the Trustee to such Guarantor in writing.

SECTION 13.07. No Set-Off.

Each payment to be made by a Guarantor hereunder in respect of the Obligations shall be payable in the currency or currencies in which such Obligations are denominated, and shall be made without set-off, counterclaim, reduction or diminution of any kind or nature.

SECTION 13.08. Obligations Continuing.

The obligations of each Guarantor hereunder shall be continuing and shall remain in full force and effect until all the obligations have been paid and satisfied in full. Each Guarantor agrees with the Trustee that it will from time to time deliver to the Trustee suitable acknowledgments of this continued liability hereunder.

SECTION 13.09. Obligations Reinstated.

The obligations of each Guarantor hereunder shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment which would otherwise have reduced the obligations of any Guarantor hereunder (whether such payment shall have been made by or on behalf of the Company or by or on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy, liquidation or reorganization of the Company or any Guarantor or otherwise, all as though such payment had not been made. If demand for, or

acceleration of the time for, payment by the Company is stayed upon the insolvency, bankruptcy, liquidation or reorganization of the Company, all such Indebtedness otherwise subject to demand for payment or acceleration shall nonetheless be payable by each Guarantor as provided herein.

SECTION 13.10. Obligations Not Affected.

The obligations of each Guarantor hereunder shall not be affected, impaired or diminished in any way by any act, omission, matter or thing whatsoever, occurring before, upon or after any demand for payment hereunder (and whether or not known or consented to by any Guarantor or any of the Holders) which, but for this provision, might constitute a whole or partial defense to a claim against any Guarantor hereunder or might operate to release or otherwise exonerate any Guarantor from any of its obligations hereunder or otherwise affect such obligations, whether occasioned by default of any of the Holders or otherwise.

SECTION 13.11. Waiver.

Without in any way limiting the provisions of Section 11.01 hereof, each Guarantor hereby waives notice or proof of reliance by the Holders upon the obligations of any Guarantor hereunder, and diligence, presentment, demand for payment on the Company, protest or notice of dishonor of any of the Obligations, or other notice or formalities to the Company of any kind whatsoever.

SECTION 13.12. No Obligation To Take Action Against the Company.

Neither the Trustee nor any other person shall have any obligation to enforce or exhaust any rights or remedies or to take any other steps under any security for the Obligations or against the Company or any other person or any property of the Company or any other person before the Trustee is entitled to demand payment and performance by any or all Guarantors of their liabilities and obligations under their Guarantees or under this Indenture.

SECTION 13.13. Dealing with the Company and Others.

The Holders, without releasing, discharging, limiting or otherwise affecting in whole or in part the obligations and liabilities of any Guarantor hereunder and without the consent of or notice to any Guarantor, may

(a) grant time, renewals, extensions, compromises, concessions, waivers, releases, discharges and other indulgences to the Company or any other person;

(b) take or abstain from taking security or collateral from the Company or from perfecting security or collateral of the Company;

(c) release, discharge, compromise, realize, enforce or otherwise deal with or do any act or thing in respect of (with or without consideration) any and all collateral, mortgages or other security given by the Company or any third party with respect to the obligations or matters contemplated by this Indenture or the Securities;

(d) accept compromises or arrangements from the Company;

(e) apply all monies at any time received from the Company or from any security upon such part of the Obligations as the Holders may see fit or change any such application in whole or in part from time to time as the Holders may see fit; and

(f) otherwise deal with, or waive or modify their right to deal with, the Company and all other persons and any security as the Holders or the Trustee may see fit.

SECTION 13.14. Default and Enforcement.

If any Guarantor fails to pay in accordance with Section 13.06 hereof, the Trustee may proceed in its name as trustee hereunder in the enforcement of the Guarantee of any such Guarantor and such Guarantor’s obligations thereunder and hereunder by any remedy provided by law, whether by legal proceedings or otherwise, and to recover from such Guarantor the obligations.

SECTION 13.15. Amendment, Etc.

No amendment, modification or waiver of any provision of this Indenture relating to any Guarantor or consent to any departure by any Guarantor or any other person from any such provision will in any event be effective unless it is signed by such Guarantor and the Trustee.

SECTION 13.16. Acknowledgment.

Each Guarantor hereby acknowledges communication of the terms of this Indenture and the Securities and consents to and approves of the same.

SECTION 13.17. Costs and Expenses.

Each Guarantor shall pay on demand by the Trustee any and all costs, fees and expenses (including, without limitation, legal fees on a solicitor and client basis) incurred by the Trustee, its agents, advisors and counsel or any of the Holders in enforcing any of their rights under any Guarantee.

SECTION 13.18. No Waiver; Cumulative Remedies.

No failure to exercise and no delay in exercising, on the part of the Trustee or the Holders, any right, remedy, power or privilege hereunder or under this Indenture or the Securities, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or under this Indenture or the Securities preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges in the Guarantee and under this Indenture, the Securities and any other document or instrument between a Guarantor and/or the Company and the Trustee are cumulative and not exclusive of any rights, remedies, powers and privilege provided by law.

SECTION 13.19. Survival of Obligations.

Without prejudice to the survival of any of the other obligations of each Guarantor hereunder, the obligations of each Guarantor under Section 13.01 and shall be enforceable

against such Guarantor without regard to and without giving effect to any right of offset or counterclaim available to or which may be asserted by the Company or any Guarantor.

SECTION 13.20. Guarantee in Addition to Other Obligations.

The obligations of each Guarantor under its Guarantee and this Indenture are in addition to and not in substitution for any other obligations to the Trustee or to any of the Holders in relation to this Indenture or the Securities (including the Purchase Agreement, and the Collateral Documents).

SECTION 13.21. Severability.

Any provision of this Article Thirteen which is prohibited or unenforceable in any jurisdiction shall not invalidate the remaining provisions and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction unless its removal would substantially defeat the basic intent, spirit and purpose of this Indenture and this Article Thirteen.

SECTION 13.22. Successors and Assigns.

Each Guarantee shall be binding upon and inure to the benefit of each Guarantor and the Trustee and the other Holders and their respective successors and permitted assigns, except that no Guarantor may assign any of its obligations hereunder or thereunder.

THE DOE RUN RESOURCES CORPORATION, a New York corporation (the “Company”), promises to pay interest on the principal amount of this Security at the applicable rate set forth herein. The Company will pay interest in cash semi-annually in arrears on April 15 and October 15 of each year (the “Interest Payment Date”), commencing April 15, 2003, provided that, on each Interest Payment Date occurring on or prior to October 15, 2005, interest may be paid, at the Company’s option, by either (a) (i) the cash payment of accrued interest at an annual rate of 3% and (ii) the issuance of additional Securities (the “PIK Notes”) with a principal amount equal to the interest accrued from the later of the Original Issue Date or the last Interest Payment Date through such date at an annual rate of 11.5% per annum (“PIK Payment”) or (b) the cash payment of accrued interest at an annual rate of 8½%. Interest on Securities issued on October 29, 2002 (the “Original Issue Date”) will accrue from the Original Issue Date until the first scheduled interest payment. Interest on the PIK Notes will accrue from the issue date thereof and not from the Original Issue Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment.

The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Record Date immediately preceding the Interest Payment Date even if the Securities are cancelled on registration of transfer or registration of exchange after such Record Date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts (“U.S. Legal Tender”). However, the Company may pay principal and interest by wire transfer of Federal funds, or interest by its check payable in such U.S. Legal Tender. The Company may deliver any such interest payment to the Paying Agent or to a Holder at the Holder’s registered address. Notwithstanding the foregoing, the Company shall pay or cause to be paid all amounts payable with respect to Restricted Securities or non-DTC eligible Securities by wire transfer of Federal funds to the account of the Holders of such Securities.

3. Paying Agent and Registrar.

Initially, STATE STREET BANK AND TRUST COMPANY (the “Trustee”), will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to the Holders.

Securities in denominations larger than $1,000 may be redeemed or purchased, as the case may be, in part.

Except as set forth in the Indenture, from and after any Redemption Date or Purchase Date, as the case may be, if monies for the redemption or purchase, as the case may be, of the Securities called for redemption or purchase, as the case may be, shall have been deposited with the Paying Agent for redemption or purchase, as the case may be, on such Redemption Date or Purchase Date, as the case may be, then, unless the Company or Renco, as the case may be, defaults in the payment of such Redemption Price or Purchase Price, as the case may be, the

Securities called for redemption or purchase, as the case may be, will cease to bear interest and the only right of the Holders of such Securities will be to receive payment of the Redemption Price or Purchase Price, as the case may be.

The Trustee and each Holder acknowledge that a release of any of the Collateral or any Lien strictly in accordance with the terms and provisions of the Collateral Documents and the terms and provisions of the Indenture will not be deemed for any purpose to be an impairment of the security under the Indenture.

10. Denominations; Transfer; Exchange.

The Securities are in registered form, without coupons. A Holder shall register the transfer of or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Registrar need not register the transfer of or exchange any

The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries to, among other things, incur additional Indebtedness or Liens, make payments in respect of its Capital Stock and merge or consolidate with any other person and sell, lease, transfer or otherwise dispose of substantially all of certain of its properties or assets.

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company, the Guarantors, their Subsidiaries or their respective Affiliates as if it were not the Trustee.
