ARTICLE 7

POST-CLOSING COVENANTS

7.1           Assignment of Certain Contracts and Leases.  Doe Run will make reasonable efforts to obtain consents to the transfer of equipment leases before the Closing Date, but to the extent equipment leases have not been transferred by the Closing Date, Doe Run, regarding the equipment in question, will not enter into new leases, will not amend the current leases, and will not take any other action with respect to the leases detrimental to Transferee.  Anything in this Agreement to the contrary notwithstanding, to the extent that any Included Contract is not assignable without the consent of another Person, this Agreement shall not be deemed to constitute or require an assignment or an attempted assignment thereof if such assignment or attempted assignment would constitute a breach thereof.  If such consent has not been obtained by the Closing Date, Doe Run agrees to:

20

(a)  Cooperate with Transferee in any reasonable arrangement designed to provide for Transferee substantially the same benefits and obligations under any such Included Contract without cost to Transferee, including:

(i)  enforcing for the benefit of Transferee any or all rights of Doe Run under any such Included Contract or;

(ii)  at Transferee’s election, not transferring, conveying, assigning or delivering the same to Transferee at the Closing, and retaining legal title or right thereto, while permitting Transferee the possession and use of such assets or rights for Transferee’s account and with Transferee receiving the benefits and burdens of such assets or rights as if such assets or rights had been so transferred, conveyed, assigned and delivered.

(b)  Take all reasonable further action to obtain such consents, approvals or novations as may be required under such instrument, applicable law or otherwise to effect the transfer of the asset or right to Transferee.

7.2           Certain Consents.  Doe Run shall use all reasonable efforts to obtain any necessary third party consents listed on Schedule 4.1(d) as soon as possible after the execution of this Agreement and prior to the Closing Date; provided, however, that the failure to obtain the same shall not be a default under this Agreement.  If any such consent cannot be obtained within ninety (90) days following the execution of this Agreement, Doe Run shall take such steps as may be necessary or requested by Transferee to give Transferee the economic effect of the same.

7.3           Contracts That Apply to or Benefit Other Doe Run Facilities.  Anything in this Agreement to the contrary notwithstanding, to the extent that any agreement, contract, license, lease, permit or other authorization, purchase or sale order, or other executory contract or commitment applies to or benefits any other facility operated by Doe Run, including but not limited to the Sales Contracts shown on Exhibit D, this Agreement shall not be deemed to constitute or require an assignment of such agreement.  Doe Run agrees to cooperate with Transferee and use its reasonable efforts to negotiate with the vendors or other third parties under such agreements to enter into new agreements that would allocate between Transferee and Doe Run the rights, interests and obligations of Doe Run under such agreements, such that the Buick Facility will continue to have made available to it the benefits needed for the Buick Business under such contracts on comparable terms.

7.4           Insurance.  Following the Closing, and so long as Transferee is a subsidiary of Doe Run, Doe Run shall provide all required property, liability and other insurance for Transferee and the Buick Business under the general corporate umbrella policies of Doe Run, with such coverages, deductions and exceptions as may be required by the applicable covenants in favor of any applicable lending institution, credit agreement or other indenture applicable to the Buick Facility or Transferee, or by any Requirements of Law, or as would be generally covered by Doe Run for its other operations of similar nature and size.

7.5           Further Assurances.  Doe Run and Transferee each agree to execute and deliver such other documents, certificates, agreements and other writings and to take such other actions as may be necessary or desirable in order to consummate or implement expeditiously the

21

transactions contemplated by this Agreement, including without limitation any and all documents necessary to assign to Transferee any of the Acquired Assets used by Doe Run in the operation of the Buick Facility that are not conveyed to Transferee at the Closing Date.

7.6Confidentiality.  After termination of this Agreement pursuant to Article 9 or as of the Closing, whichever occurs first, Doe Run will not use or disclose to any person, any trade or business secrets relating to the Buick Facility and Buick Business, and Transferee will not use or disclose to any person any trade or business secrets of Doe Run not related to the Buick Facility or the Buick Business and otherwise obtained from Doe Run as a result of this Agreement, provided that, (i) either party may use or disclose any such information that has been publicly disclosed (other than by such party after the Closing Date); (ii) to the extent that a party may become legally compelled to disclose any of such information, the party may disclose such information only if such party has used its reasonable commercial efforts (and shall have afforded the other party) the opportunity to obtain an appropriate protective order or other satisfactory assurance of confidential treatment for the information required to be so disclosed; or (iii) disclosures made to the applicable Governmental entity in connection with any transfer of the Governmental Permits.

7.7Retention of Records; Preparation of Certain Tax Returns; Litigation Cooperation.

(a)           For a period of five (5) years after the Closing Date, Transferee and Doe Run will provide, upon reasonable notice, to the other or its officers, counsel, independent accountants and other duly authorized representatives or agents, reasonable access during normal business hours, (i) in the case of Doe Run’s obligation to Transferee, to the books, records and other data of Doe Run; and (ii) in the case of Transferee’s obligation to Doe Run, to the books, records and other data of Transferee, in each case to the extent that they relate to the Buick Facility or the Acquired Assets and only to the extent that such access is necessary to enforce a right under this agreement or to satisfy reasonable corporate purposes of the party requesting such access.  In each case, such access will include the right to conduct interviews with the other party’s officers and employees, to transcribe extracts from such books, records or other data or to make copies thereof.

(b)           Each of Transferee and Doe Run agrees that, for a period of five (5) years following the Closing Date, it will retain and not destroy, discard, deface or otherwise alter any of the books, records or other data, including, without limitation, data analysis and tapes, relating to the Buick Facility in its possession on the Closing Date, without first notifying the other party and giving the other party, at such other party’s expense, the opportunity to take custody of such books, records or other data (it being understood that Doe Run shall transfer to Transferee at Closing possession of the books, records and other data described in Section 2.1(f)).

(c)           Doe Run and Transferee shall cooperate with each other in connection with the preparation, execution and filing with the Internal Revenue Service of information returns required by Section 1060 of the Code and the regulations thereunder, relating to the transactions contemplated herein.

22

(d)           Upon reasonable notice, each party will make available for inspection by the other such business records and books of accounts of the Buick Facility acquired hereunder as are needed to prepare financial statements and tax schedules and related documents necessary for the filing by such party of its tax returns or reports for outstanding tax years and otherwise make available for inspection such information in connection therewith or in connection with tax examinations or audits as such party may reasonably request from time to time.  Each party agrees to cooperate with the other in the preparation of any portions of consolidated or combined federal, state, local or foreign income, sales, employment, occupational, transfer, property and other tax returns and filings pertaining to the Buick Facility or the Acquired Assets.

(e)           After the Closing Date, Transferee and Doe Run will make available to the other, as reasonably requested, and, subject to the prior written approval of the other (which approval shall not be unreasonably withheld or delayed), to any taxing authority, information, records or documents in their possession relating to tax Liabilities or potential tax Liabilities of the Buick Facility for periods prior to and including the Closing Date.

(f)            After the Closing Date, and subject to the Facilities Operating Agreement, Transferee and Doe Run shall provide reasonable cooperation, and will cause their officers and employees to provide reasonable cooperation with the other party in the furnishing of information, testimony and other assistance in connection with any action, judicial or administrative proceeding, claim or dispute to which either party is or becomes a party relating to the Acquired Assets, Assumed Liabilities or the Buick Facility (other than a dispute between the parties).  The party requesting such assistance shall promptly upon presentation of an invoice (with appropriate supporting documentation) reimburse the party providing such assistance for reasonable costs and expenses incurred in providing such assistance.

7.8Mail and Other Communications.

(a)           Doe Run hereby authorizes Transferee after the Closing Date to receive and open all mail and other communications addressed to Doe Run received by Transferee, and to act with respect to such mail and other communications in such manner as Transferee may elect if such mail and other communications relate to the Buick Facility and related rights and obligations of Transferee under this Agreement, or if such mail and other communications do not so relate, to forward such mail and other communications promptly to Doe Run.

(b)           After the Closing Date, Doe Run shall promptly deliver to Transferee the original of any mail or other communication received by it pertaining to the Buick Facility and related rights and obligations of Transferee under this Agreement, and any monies, checks or other instruments of payment to which Transferee is entitled, and Transferee shall promptly deliver to Doe Run any monies, checks or instruments of payment to which Doe Run is entitled.  On the Closing Date, Doe Run shall deliver to Transferee the most recent listing available of invoices and the unpaid amount of each accounts receivable of the Buick Facility.  All payments received by Transferee after the

23

Closing Date from customers shall be applied to the applicable invoice of Doe Run or Transferee, as the case may be, referenced on such payment.  If a payment is received that contains no such reference and it cannot otherwise be determined whether the payment relates to an invoice of Doe Run or Transferee, it shall be deemed to relate to the earliest of Doe Run’s accounts receivable due from such customer; provided, however, that Transferee shall not otherwise be obligated to collect any accounts receivables for or on behalf of Doe Run’s account.

7.9Retention of Bond and Closure Obligations.  After the Closing Date, Doe Run agrees to maintain in full force and effect that certain letter of credit or other security as may be required from time to time by the applicable regulatory agencies, pertaining to the closure obligations and operating permits of the Buick Facility; provided, however, that Doe Run shall have the option from time to time to replace such letter of credit with another instrument acceptable to the applicable regulatory bodies and to the Transferee.  Upon closure of the Buick Facility, the initial closure expenditures of the amount covered by Doe Run’s letter of credit shall be for Doe Run’s account and Doe Run shall pay such amount directly to the Transferee for such expenditures upon demand.  If the amount of closure expenditures actually incurred by Transferee is less than such amount paid by Doe Run, Transferee shall immediately refund the excess.

ARTICLE 8

INDEMNIFICATION

8.1Indemnification by Doe Run.  Doe Run shall and hereby agrees to indemnify, defend and hold Transferee harmless against and in respect of:

(a)           All debts, Liabilities and obligations of Doe Run of any nature, whether accrued, absolute or contingent or otherwise, existing or arising on or resulting from events which occurred on or before the Closing Date, to the extent not expressly assumed by Transferee hereunder, which indemnity of Doe Run in favor of the Transferee shall include but not be limited to, the Excluded Liabilities; and

(b)           Any Liability, loss, claim damage or deficiency resulting directly or indirectly from any misrepresentation, breach of warranty or non-fulfillment of any agreement on the part of Doe Run under this Agreement, or from any misrepresentation in or omission from any certificate or other instrument furnished or to be furnished to Transferee hereunder.

8.3Defense Against Asserted Claims.  If any claim or assertion of liability is made or asserted against a party entitled to be indemnified pursuant to this Section 8 (an “Indemnified

24

Party)”, the Indemnified Party shall with reasonable promptness and, in any event, no later than ten days prior to the time the response to such claim or assertion of Liability must be given, give to the other party (the “Indemnifying Party”) written notice of the claim or assertion of Liability and request the Indemnifying Party to defend the same.  The Indemnifying Party shall, at the Indemnifying Party’s expense, assume the defense of such claim or assertion.  The Indemnified Party shall have the right to employ separate counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless (i) the engagement thereof has been specifically authorized by the Indemnifying Party in writing, or (ii) the Indemnifying Party has failed to promptly assume the defense of such action.  The Indemnified Party shall not be permitted to enter into any settlement or compromise involving any action or relief other than money unless the Indemnifying Party shall have been notified in writing of the proposed settlement or compromise and shall have consented in writing thereto, which consent shall not be unreasonably withheld.  The parties will cooperate with each other in the defense of any such action and the relevant records of each shall be available to the other with respect to such defense.

8.4Indemnification Limitation.  An Indemnified Party shall be entitled to indemnification hereunder only to the extent that the amount of losses, costs, expenses and damages suffered or incurred by the Indemnified Party exceed in the aggregate $500,000.00 (the “Deductible Amount”).  Each party shall supply such information supporting any claim for indemnification hereunder, including information concerning such expenditures as are claimed toward the Deductible Amount, as the other party shall reasonably request.
