business of producing, recycling, fabricating or selling non-ferrous metals (the parties acknowledge DOE RUN’s trading area is global), as of the date of cessation of MR. CHAPUT’s engagement with DOE RUN. However, nothing contained in this subparagraph 20(B)(ii) shall be deemed to prohibit MR. CHAPUT from any engagement in the natural resources industry, provided the engagement does not involve a business engaged in producing, recycling, fabricating or selling non-ferrous metals, and further provided MR. CHAPUT, in any such engagement, shall comply with the provisions of subparagraph 20(B) hereto.

21.                                 No Disparagement.  MR. CHAPUT agrees that he will not disparage DOE RUN, its parent companies, its affiliate companies, its subsidiary companies, and their directors, officers, shareholders, employees, agents, attorneys, successors and assigns or solicit or encourage others to do so, and he will not make, solicit or encourage any comments, statements or the like to the media or to others which are derogatory or detrimental to the good name or business reputation of DOE RUN.

DOE RUN agrees that it will not disparage MR. CHAPUT.  In the event a comment, derogatory or detrimental to the good name or business of reputation of MR. CHAPUT, is published or broadcast by a media entity, and it is made by or attributed to an employee of DOE RUN and DOE RUN is advised of it by MR.

22.                                 Confidentiality.  MR. CHAPUT agrees that the terms and conditions of this Agreement are confidential and he agrees not to disclose or disseminate information concerning this Agreement to anyone other than his spouse, his lawyers or accountants, or government taxing authority, except as may be required by law, or by order of court, without the prior written permission of DOE RUN.  Nothing in this Agreement shall prevent Doe Run

The parties shall jointly request the AAA to designate a panel of arbitrators, and either the parties mutually shall agree upon one of the arbitrators or, in the absence of mutual agreement, each side shall alternatively strike a name from the list of arbitrators commencing with the party seeking arbitration, and the name remaining on the list shall be deemed chosen as the arbitrator.

The parties agree that the issue before the arbitrator shall be whether one of the parties breached the terms of this Agreement, and, if so, what are the appropriate damages, if any, except that the arbitrator will have no authority to award punitive damages or damages for non-economic injuries.  The finding of the arbitrator shall be final and binding on both parties.  The arbitrator shall have no power to add to, detract from, or alter this Agreement in any way, and, notwithstanding any AAA rule to the contrary, the arbitrator shall have no power to award, and may not award, punitive or non-economic damages.  The arbitrator’s decision shall be subject to review only as provided under the Federal Arbitration Act where the arbitrator has failed to base his or her decision on the Agreement.  Pending final decision by the arbitrator, there shall be no other legal action taken by either party to the controversy.

The arbitration shall take place in the State of Missouri in the metropolitan St. Louis area.  All costs and expenses incidental to and arising out of the arbitration (e.g., arbitrator’s fee) shall be borne by the losing party, but each side shall pay its own attorneys’ fees.

24.                                 Vested Rights.  The parties further agree that this Agreement shall not adversely affect, alter, or extinguish any vested rights that MR. CHAPUT may have with respect to any pension or retirement benefits to which he is or will be entitled by virtue of his employment with DOE RUN, and nothing in this Agreement will prohibit MR. CHAPUT from enforcing his rights to any such pension or retirement benefits, including but not limited to DOE RUN’s 401(k) Plan, the Doe Run Defined Benefit Plan, and the Doe Run Resources Corporation Supplemental Employee Retirement Plan.
