St. Louis, Missouri  63146 Re:Net Worth Appreciation Agreement Dear Mr : This letter, dated as of
November 1 (the Base Date), 2002 sets forth the agreement between you and The
Doe Run Resources Corporation, (the Company)
with respect to your Net Worth Appreciation Benefit, intended to constitute
additional incentive compensation to you as an employee of the Company.  Upon your execution of this letter, any
prior Net Worth Appreciation Agreement or amendments thereto between you and DR
Acquisition Corp or the Company shall terminate and all obligations pursuant to
such agreement as amended shall cease. 1.     Vesting. (a)   On the Base Date in 2005,
provided that you have been continuously in the employ of the Company from the
date hereof through that date, you shall receive a Net Worth Appreciation
Credit of   % and on the Base Date in each of the years 2006
and 2007 you shall receive an additional Net Worth Appreciation Credit of   %, provided that you have been continuously
in the employ of the Company from the date hereof to the applicable Base Date for a maximum credit, if you
remain in the employ of the Company continuously through the Base Date in 2007, of   % (the Maximum Credit).  The aggregate number of Net Worth
Appreciation Credits received pursuant to this Section 1(a) on or prior to a
given date shall be hereinafter referred to as Vested Credits.  You shall not receive any credit unless you
remain in the employ of the Company from the date hereof continually until the Base Date in 2005, and thereafter you
shall not receive credit for any partial year, provided that (a) if your
employment terminates due to death or permanent disability preventing you from
performing your usual employment functions and duties (disability) on or after the Base Date in 2003 and prior to the Base Date in 2005, you shall receive a credit of   % if such termination is prior to the Base Date in 2004 and   % if such termination is on or after the Base Date in 2004 and prior to the Base Date in 2005, and (b) if
your employment terminates after the Base
Date in 2005 and before the Base
Date in 2007, due to death or disability, you shall receive a credit
of   % for the partial year in which the
termination takes place (in addition to all credits previously accrued). 
   (b)   In addition, in
consideration of your having been continually employed by the Company and
serving in Peru on expatriate assignment to Doe Run Peru SRL or one of its
affiliates through [            ], you
have a separate Peruvian credit of   %
(Peru Credit). 2.     Treatment of Matters in Calculation of
Benefits. (a)   For the purposes of
calculating the benefits payable under this Agreement, the Company will
continue to calculate Federal corporate income taxes and the corporate income
taxes for those jurisdictions in which the Company and its subsidiaries do business,
for the fiscal periods or portions thereof beginning on or after the Base Date in 2002, as if the Company
and its subsidiaries had continued to have C corporation status under the
Federal Internal Revenue Code and under state and local tax laws, in accordance
with the provisions of generally accepted accounting principles and the
Internal Revenue Code and regulations thereunder and under state and local tax
laws applicable to C corporations as from time to time in effect
(C Status).  Such tax calculations
will include calculations of current and deferred tax expense or benefit and
current and non-current tax assets and liabilities (C Taxes) and the
differences (Tax Differences) between the C Taxes and the taxes as
recorded by the Company and its subsidiaries while being designated a qualified
subchapter S subsidiary (S Taxes). (b)   Cumulative Income Statement
Tax Difference shall be the cumulative difference in income tax expenses or
benefit between the calculation of the C Taxes and S Taxes, in each
case calculated for the tax periods or portions thereof beginning on or after the Base Date in 2002, and through the end
of the calculation period.  Cumulative
Cash Flow Tax Difference shall be the cumulative difference in income tax
payments, net of refunds, between the calculation of the C Taxes and
S Taxes in each case made after the Base Date in 2002 and applicable to
earnings of the Company on and after the Base Date in 2002, or which would be
in the case of C Taxes, or are in the case of S Taxes, immediately due and
payable, contemporaneously with the payment of any Distributions, as defined
below. A Distribution for purposes of this Agreement shall mean a dividend,
management fee, or any other form of distribution to The Renco Group, Inc. (Renco)
or an affiliate of Renco other than a subsidiary of the Company  (including a transfer to Renco of assets in
any form whether as cash or other form of value which shall have the effect of
reducing the net worth of the Company), in excess of the Renco Amount (as
defined herein), provided that payments made in respect of any debt to Renco,
including, but not limited to, principal interest and fees thereon, or the
preferred stock of the Company, including, but not limited to, dividends
thereon and redemptions thereof, shall not be a Distribution.  The Renco Amount shall be equal to
$2,400,000 per annum, calculated cumulatively so that unused portions shall
carry over to succeeding years. (c)   In connection with the
annual audit of the financial statements of the Company, the Companys Board of
Directors will require that the independent public accountants issue a special
report indicating their agreement with the Tax Differences.  2 
   3.     Net Worth Appreciation Benefit.  At the time and in the manner specified in
Section 4, you shall be entitled to a net worth appreciation payment (Payment) equal to the sum of: (a)    (A) the product of the
Vested Credits and the Net Worth Increment, as defined below, less (B) the
product of the Vested Credits and the Cumulative Income Statement Tax
Difference (the calculation period shall end at the end of the Companys fiscal
quarter immediately preceding your date of termination) and excluding such
Cumulative Income Statement Tax Difference to the extent equal to Cumulative
Cash Flow Tax Difference utilized in calculating amounts payable under
Paragraph 5(a). The Net Worth Increment is the amount, if any, by which
the consolidated net worth of the Company and its subsidiaries, as at the end
of its fiscal quarter immediately preceding the date of your termination,
exceeds its consolidated net worth as of the date hereof, provided, however,
that any increase in consolidated net worth resulting from a capital
contribution to the Company or the sale of stock of the Company shall be
disregarded in calculating Net Worth Increment, and further provided that
preferred stock of the Company and cash payments of dividends and payments in
kind thereon shall be treated as debt of the Company for purposes of
calculating consolidated net worth.  For
clarity, it is understood that the Net Worth Increment will not include charges
for interest on the restructured debt of the Company to the extent not included
as interest expense under GAAP as accounted for under FAS 15, nor will the Tax
Differences include any benefit for such interest on such restructured debt.
And; (b)   the product, if positive, of
(i) the Peru Credit multiplied by (ii) the Retained Peruvian
Cumulative Net Income.  The Retained
Peruvian Cumulative Net Income is the amount, if any, of the cumulative net
income of Doe Run Peru SRL available to the holders of its common stock from
October 23, 1997, the date of your assignment to Doe Run Peru SRL until
the date when such assignment is effectively completed, less the sum of (i)
imputed interest of 111⁄4% per annum, assumed to have been payable on
$125,000,000 of the $139,062,500 Subordinated Promissory Note of the Company in
favor of The Doe Run Resources Corporation (Resources), initially due October
1, 2005 (the Subordinated Note) (net of any income tax benefits which would
have resulted had such interest actually been charged by Resources) calculated
from September 12, 2002 until such time that $125,000,000 of the Subordinated
Note is paid in full or in part, and if partially paid, the revised amount
shall be thereafter used in the imputed interest calculation until paid in
full, and (ii) the amount of any dividends paid by Doe Run Peru to the holders
of its common stock during such period, but only if you received actual cash
payments based on such dividends as outlined in Section 5(c)  below. The determination of the independent public
accountants for the Company as to the Net Worth Increment and Retained Peruvian
Cumulative Net Income, made in accordance with generally accepted accounting
principles, consistently applied, shall be conclusive on each of us. If there
is no Net Worth Increment, no amount shall be payable pursuant to Section 3(a).  If there is no Retained Peruvian Cumulative
Net Income, no amount shall be payable pursuant to Section 3(b).  If your employment is terminated for cause,
you shall not be entitled to receive any Payment.  3 
   4.     Payment.  The Payment shall be payable to you (or your designee or estate)
in 40 equal quarterly installments, without interest, commencing three months
after the termination of your employment, and at 3 month intervals
thereafter.  Notwithstanding any
provision in this Agreement, the Company shall not be required to pay you (i)
any Payment, where the making of such Payment would violate any agreement
between the Company and any lender of the Company, or (ii) in the event that
any agreement between the Company and any lender of the Company limits the
aggregate amount that the Company may pay as bonuses, net worth appreciation
payments, profit sharing payments or other payments of similar nature
(Restricted Payments) during any period, any Payment in excess of your pro
rata portion of the aggregate amount of applicable Restricted Payments which
the Company is permitted to pay.  In the
event that the Company is unable to make a Payment due to the preceding
sentence, the Companys obligation to make such Payment shall be deferred until
such time that the Company is permitted to make such Payment pursuant to the
preceding sentence. 5.     Dividends; Sale of Substantially All of
the Companys Stock or Assets. (a)   If and in the event that the
Company shall make a Distribution while you shall be employed by the Company,
then you shall be entitled to receive, as additional compensation, (Additional
Compensation Benefit) an amount equal to (A) the excess of (i) the
product of the Maximum Credit and the cumulative Distributions paid by the
Company subsequent to the Base Date in 2002 over (ii) the product of the
Maximum Credit and any positive Cumulative Cash Flow Tax Difference less
(B) the amount of Additional Compensation Benefit previously paid to you
subsequent to the Base Date in 2002. 
This provision shall not apply to intercompany payments among the
Company and its own wholly-owned subsidiaries or among two wholly-owned
subsidiaries of the Company, or to reimbursement to Renco for a proportionate
part of costs, such as audit charges and insurance premiums, paid by Renco on
behalf of itself and its subsidiaries, including the Company; (b)   If, while you shall be
employed by the Company (and whether before or after the Base Date in 2007),
all or substantially all the stock or assets of the Company shall be sold to a
person who is not an affiliate of Ira Leon Rennert, or if The Renco Group, Inc.
sells a controlling interest in the Company, then, upon the closing of such
sale, your full Maximum Credit shall be deemed to be vested, and you shall be entitled
to receive, in kind and on the same terms and conditions as the Company or its
shareholder is being paid as payment in full of your participation, an amount
equal to (A) the product of the Maximum Credit and any Net Proceeds (as defined
below) of the sale, plus (B) the product of the Maximum Credit and the
cumulative Distributions paid by the Company subsequent to the Base Date in
2002, less (C) the product of the Maximum Credit and the Cumulative Income
Statement Tax Difference through the date of sale, and less (D) the amount
of any Additional Compensation Benefit previously paid to you subsequent to the
Base Date in 2002.  Net Proceeds, for
purposes hereof, shall be equal to the amount, if any, of  the proceeds of the sale after deducting all
expenses of the sale, all applicable federal, state and local taxes, all
liabilities retained by the seller, and all amounts paid or due to holders of
the Companys preferred stock. Except for such payment, neither you nor the
Company shall have any further rights or liabilities hereunder.  4 
   (c)   In addition, if while you
are serving in Peru at Doe Run Peru SRL or one of its affiliates, Doe Run Peru
SRL pays cash dividends to its common stockholders and subsequent to such
payment while you are serving in Peru at Doe Run Peru SRL or one of its
affiliates, the Company pays dividends to its common stockholders, then, in
addition to the other payments to you under this Section, the Company shall
make a cash payment to you equal to the lesser of (a) one percent of the
cash dividend paid by Doe Run Peru SRL or (b) the excess of one percent of
the cumulative Distributions paid by the Company subsequent to November 1,
2002 over one percent of any positive Cumulative Cash Flow Tax Difference,
less, in either case, all amounts previously paid to you pursuant to this
provision since November 1, 2002. 6.     Condition Precedent. The Companys
obligation to make the Payment to you shall be conditioned on your faithful
adherence to your employment arrangements with the Company and on your
refraining from engaging, during the period over which such payments are to be
made to you, directly or indirectly in any activity which is competitive with
the business engaged in by the Company at the date of termination of your
employment.  If you do engage in any
such competitive activities, then we shall no longer be obligated to make any
payments to you hereunder. 7.     Notice.  Any notices to be sent pursuant hereto shall be sent by hand,
certified or registered mail or overnight service to you, at the address
indicated above and a copy to The Renco Group, Inc. at 30 Rockefeller
Plaza, New York, NY 10112, 42nd floor, to the attention of Ira
