Loan and Security Agreement                                        Page 4 of 12

<PAGE>

purpose of this Agreement and to establish and protect the rights, interests
and remedies created, or intended to be created, in favor of Lender hereby
authorizing Lender, in such jurisdictions where such action is authorized by
law, to effect any such recordation or filing of financing statements without
Debtor's signature, and to file as valid financing statements in the
applicable financing statement records, photocopies hereof, of the
Supplement, Note and of any other financing statement executed in connection
herewith;

                  (viii)   warrant and defend its good and marketable title to
the Equipment, and Lender's perfected Security Interest in the Collateral,
against all claims and demands whatsoever (hereby agreeing that the Equipment

dated as of June 11, 1999, between Aero Transporte, S.A. and Doe Run Peru,

                  (xiii)   within 45 days after the end of each calendar
quarter, unless such information shall have been previously provided, furnish

                  (xiv)    maintain, or cause to be maintained, with respect to
the Equipment (A) all risk physical loss insurance for an amount at least equal
to the outstanding Loan balance with respect to the Equipment and (B) public
liability and property damage insurance with respect to the Equipment as set
forth in the Supplement. Such liability insurance shall be on an occurrence
basis rather than a claims made basis and operate with respect to the Lender as
a separate policy, except as to the limits of liability. Such insurance shall be
primary insurance up to and including the stated policy limits and not excess
over other coverage. Such insurance shall (1) with respect to liability
insurance, name Lender as first named insured, (2) with respect to all risk
physical loss insurance, name Lender as loss payee and first named insured, (3)
waive any and all rights of subrogation which the insurers may have or may
acquire against the Lender, and (4) be with companies satisfactory to Lender.
The Lender has the right to carry additional insurance at its own expense,
provided that such additional insurance does not increase the cost to the Debtor
of carrying the required insurance. There shall be no right of contribution with
respect to any insurance maintained by Lender, Debtor or any other person. All
insurance required hereunder shall provide that coverage may not be altered or
canceled by the insurer without thirty (30) days' prior written notice to
Lender. Losses with


Loan and Security Agreement                                        Page 5 of 12

<PAGE>

respect to physical loss in excess of Twenty Thousand Dollars ($20,000) shall
be adjusted only with and paid to, Lender and its assignee, if any, and so
long as no Event of Default shall have occurred and be continuing, shall be
made available to Debtor to effect the necessary repairs and rehabilitation
of the Equipment. Such insurance shall not be invalidated, as against Lender,
by any action or inaction of Debtor or any other person and shall insure
Lender regardless of any breach or violation by Debtor or any other person of
any warranties, declarations or conditions contained in the policies
evidencing such insurance or in applications for such insurance. All
insurance required hereunder shall be satisfactory to Lender and shall
contain such other endorsements as may be requested by Lender. Debtor hereby
appoints Lender as Debtor's attorney-in-fact to make claim for, receive
payment of and execute and endorse all documents, checks or drafts for loss
or damages or return premium under any insurance policy issued on the
Equipment; provided however, Lender shall not exercise this power of attorney
unless an Event of Default has occurred and is continuing. Debtor's
obligation to keep the Equipment insured as provided herein shall continue
until all Obligations have been paid in full.

                  The insurance policy shall be endorsed to provide that the
Lender will have no liability for premiums or other costs of the insurance
required hereby. The insurance carried by Debtor with respect to the Equipment
shall be no less favorable in scope or amount than that carried by Debtor with
respect to other comparable equipment. Such insurance shall not include any
self-insured retentions. Such insurance shall not include any deductibles except
for any deductibles which are consistent with Debtor's industry standard and are
acceptable to Lender.

                  Debtor shall furnish Lender with insurance certificates
evidencing such insurance prior to the Acceptance Date of the applicable
Supplement and prior to the expiration of each such certificate. Each
certificate of insurance shall be attached to a letter from an insurance broker
acceptable to Lender confirming that the underlying insurance policy summarized
by the certificate of insurance complies with the requirements of this Section.
At Lender's request, Debtor shall provide to Lender a copy of the entire
insurance policy covering the Equipment.

         (b)      It will not without the prior written consent of Lender:

                  (i)      except as contemplated in the Management Agreement,
the Lease and the Services Agreement, sell, convey, transfer, exchange, lease or
otherwise relinquish possession or dispose of any of the Collateral or attempt
or offer to do any of the foregoing without Lender's prior written consent which
will not be unreasonably withheld;

                  (ii)     create, assume or suffer to exist any lien, mortgage,
security interest, financing statement or other encumbrance of any kind
whatsoever ("Lien") upon the Collateral except for the Security Interest created
hereby;

                  (iii)    TRANSFER, LEASE, ASSIGN OR PLEDGE THE EQUIPMENT OR
ANY PART THEREOF OR ANY INTEREST THEREIN, EXCEPT IN THE NORMAL COURSE OF
BUSINESS WITHOUT LENDER'S PRIOR WRITTEN CONSENT, WHICH WILL NOT BE UNREASONABLY
WITHHELD;

                  (iv)     change the form of organization of its business;

                  (v)      without thirty (30) days' prior written notice to

Loan and Security Agreement                                        Page 6 of 12

<PAGE>

                  (vi)     move or change the principal base of any of the
Equipment from the location specified on the Supplement relating thereto without
the prior written consent of Lender which will not be unreasonably withheld; or

                  (vii)    make or authorize any improvement, change, addition
or alteration to the Equipment which would materially and adversely impair its
originally intended function or use or its value. Notwithstanding the foregoing,
the Equipment shall be maintained in compliance with all service bulletins
issued or supplied by any manufacturer of any Item, all Airworthiness Directives
and Regulation revisions applicable to the Equipment issued or supplied by the
United States Department of Transportation Federal Aviation Administration
("FAA"), and be sufficient to enable the airworthiness certification of each
Item to be maintained in good standing at all times.

         (c)      It will cause to be obtained as promptly as possible but no
later than August 31, 1999 or such later date as provided by applicable law in
the case of actions of governmental agencies, or such later date as the Lender
may agree, all actions and proceedings required to be taken by the Lease and by
applicable Peruvian law to lawfully operate the Equipment in Peru, including
without limitation, the following:

operation of the Equipment to be issued by the United States FAA.

         In the event Lender consents to any of the foregoing acts, Debtor
agrees that Lender may charge Debtor a reasonable documentation and
administration fee. Consent to any of the foregoing acts shall not be deemed to
be consent to any subsequent similar act.

SECTION 6. EVENT OF LOSS.

         "Event of Total Loss" with respect to the Equipment means (i) the
actual or constructive loss or loss of use thereof, due to theft, destruction,
damage beyond repair or to an extent which makes repair uneconomical, or (ii)
the condemnation, confiscation or seizure thereof, or requisition of title
thereto, or use thereof, by any Person. "Person" means an individual,
partnership, corporation, trust, unincorporated association, joint venture,
limited liability company, governmental authority or other entity of whatever

actual or constructive loss or loss of use thereof, due to theft, destruction,
damage beyond repair or to an extent which does NOT make repair uneconomical; or
(ii) the condemnation, confiscation or seizure thereof or requisition of title
thereto, which does not involve a loss of the equipment or the loss of use
thereof.

         Should any item of Equipment suffer an Event of Total Loss, Debtor
shall make a payment as described herein on the corresponding Note within 30
days thereafter. The amount to be paid shall be (i) the unpaid principal amount
of such Note and (ii) all other amounts then due and owing hereunder and under
the Note, but reduced by the total insurance proceeds paid to and retained by

automatic, without any notice by Lender).

                  (ii)     Exercise all other rights and remedies available to
it, whether under this Agreement, under any other instrument or agreement
securing, evidencing or relating to the Obligations, under the applicable
Uniform Commercial Code, or otherwise available at law or in equity.

         (c)      Without limiting the generality of the foregoing, Debtor
agrees that in any such event, Lender, without demand of performance or other
demand, advertisement or notice of any kind (except the notice specified below
of time and place of public or private sale) to or upon Debtor or any other
Person (all and each of which demands, advertisements and notices are hereby
expressly waived), may forthwith do any one or more of the following: collect,
receive, appropriate and realize upon the Collateral or any part thereof, and
sell, lease, assign, give an option or options to purchase or otherwise dispose
of and deliver, the Collateral (or contract to do so), or any part thereof, in
one or more parcels at public or private sale(s) at such place(s) and at such
price(s) as it may reasonably deem appropriate, for cash or on credit or for
future delivery without the assumption of any credit risk. Lender shall have the
right upon any such public sale(s), and, to the extent permitted by law, upon
any such private sale(s), to purchase the whole or any part of the Collateral so
sold, free of any right or equity of redemption of Debtor, which right or equity
is hereby expressly released. Debtor further agrees, at Lender's request, to
assemble (at Debtor's expense) the Collateral and make it available to Lender at
such place(s) which Lender shall select, whether in Peru or the continental
United States. Lender shall apply the net proceeds of any such collection,
recovery, receipt, appropriation, realization or sale (after deducting all
reasonable costs and expenses of every kind incurred therein or incidental to
the care, safekeeping or otherwise of any or all of the Collateral or in any way
relating to the rights of Lender hereunder, including reasonable attorneys' fees
and legal expenses) to the payment in whole or in part of the Obligations, in
such order as Lender may elect. Debtor agrees that Lender need not give more
than 10 days' notice of the time and place of any public sale or of the time
after which a private sale may take place and that such notice is reasonable
notification of such matters. Debtor shall be liable for any deficiency if the
proceeds of any sale or disposition of the Collateral are insufficient to pay
all amounts to which Lender is entitled. Debtor agrees to pay all costs of
Lender, including reasonable attorneys' fees, incurred with respect to
collection of any of the Obligations and enforcement of any of Lender's rights
hereunder. To the extent permitted by law, Debtor hereby waives presentment,
demand, protest or any notice (except as expressly provided in this Section 7)
of any kind in connection with this Agreement or any Collateral.

SECTION 8. MISCELLANEOUS.

         (a)      No delay or omission in exercising any right, power or remedy
accruing to Lender upon any breach or default by Debtor under this Agreement
shall impair any such right, power or remedy; nor shall any such delay or
omission be construed as a waiver of any breach or default, or of any similar
breach or default thereafter occurring; nor shall any waiver of a single breach
or default be deemed a waiver of any subsequent breach or default; nor shall
consent by Lender to any act of Debtor be deemed to be consent to any subsequent
similar act.

         (b)      All notices, requests and demands to or upon any party hereto
shall be deemed duly given or made when sent if given by telecopier, when
delivered if given by personal delivery or overnight commercial carrier, on the
third calendar day after deposit in the United States mail, certified mail,
return receipt requested, addressed to such party at its address set forth in
the first paragraph of this Agreement or such other address or telecopier number
as may be hereafter designated in writing by such party to the


Loan and Security Agreement                                        Page 9 of 12

other party hereto. All notices to Lender shall be to the attention of Vice
President-Operations, and if by fax to (562) 627-3002. All notices to Debtor
shall also be given to Guarantor at The Doe Run Resources Corporation, 1801
Park 270 Drive, Suite 300, St. Louis, MO 63146 to the attention of the Chief
Financial Officer.

         (c)      Debtor agrees, whether or not the contemplated transactions
are consummated:

                  (i)      to pay or reimburse Lender for (A) all fees, taxes
and expenses of whatever nature incurred in connection with the creation,
preservation and protection of Lender's Security Interest in the Collateral,
including, without limitation, all filing and lien search fees, payment or
discharge of any taxes or Liens upon, or in respect to, the Collateral, and all
other fees and expenses in connection with protecting or maintaining the
Collateral or in connection with defending or prosecuting any actions, suits or
proceedings arising out of, or related to, the Collateral, and (B) all other
costs or expenses Debtor has agreed to pay, and (C) all costs and expenses
(including reasonable attorneys' fees and legal expenses) of Lender in
connection with the enforcement of this Agreement and the other Loan Documents;
and

                  (ii)     to defend at its own cost and to indemnify and hold
harmless Lender, its successors and assigns, and their respective agents and
employees, from and against any and all losses, claims, intellectual property,
infringements, costs, expenses (including attorneys' fees), damages and
liabilities (including those for strict liability in tort), however caused,
resulting directly or indirectly in any manner from the issuance of Debtor's
purchase order, assignment of Debtor's purchase order or agreement to purchase,
Debtor's 's failure, delay or refusal to accept delivery of any Equipment, the
ownership, purchase, maintenance, possession, return or disposition of the
Equipment, or directly or indirectly from or pertaining to the use, condition,
design (including without limitation latent or other defects whether or not
discoverable) or operation of the Equipment, ordinary wear and tear excepted, or
the performance of this Agreement (including without limitation such losses,
claims, costs, expenses, damages and liabilities arising from the death or
injury to agents or employees of Debtor or Lender or any third person, or damage
to the property of Debtor or Lender, their agents or employees, or any third
person), (the foregoing being referred to as the "Indemnified Liabilities"),
provided, that Debtor shall have no obligation hereunder with respect to
Indemnified Liabilities arising from the gross negligence or willful misconduct
of Lender. If Debtor fails to perform or comply with any of its agreements
contained in this Agreement and Lender shall itself perform, comply or cause
performance or compliance, the expenses of Lender so incurred, together with
interest thereon at the Default Rate, shall be payable by Debtor to Lender on
demand and until such payment is made shall constitute Obligations hereunder.
The agreements and indemnities contained in this paragraph shall survive
termination of this Agreement and payment of the Note.

         (d)      This Agreement, together with the Note, Supplement and addenda
or amendments hereto, contains the complete, final and exclusive statement of
the terms of the agreement between Lender and Debtor related to the contemplated
transactions, and neither this Agreement, nor any terms hereof, may be changed,
waived, discharged or terminated orally, but only by an instrument in writing
signed by the party against which enforcement of a change, waiver, discharge or
termination is sought.

         (e)      This Agreement shall be binding upon, and inure to the benefit
of, Debtor and Lender and their respective successors and assigns, except that
Debtor may not assign or transfer its rights hereunder or any interest herein
without the prior written consent of Lender.

         (f)      Headings of sections and paragraphs are for convenience only,
are not part of this Agreement and shall not be deemed to affect the meaning or
construction of any of the provisions hereof. Any provision of this Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the


Loan and Security Agreement                                       Page 10 of 12

<PAGE>

remaining provisions hereof, and any such prohibition or unenforceability
shall not invalidate or render unenforceable such provision in any other
jurisdiction.

         (g)      Debtor hereby authorizes Lender to correct patent errors and
to fill in such blanks as serial numbers and dates herein and in the Note,
Supplement and in any document executed in connection herewith.

         (h)      This Agreement may be executed by the parties hereto in
separate counterparts, each of which when so executed and delivered shall be an
original, but all such counterparts shall together constitute the same
instrument.

         (i)      To the extent permitted by applicable law, Debtor hereby
waives any provision of law which renders any provision of this Agreement
prohibited or unenforceable in any respect. Any action by Debtor against Lender
for any default by Lender under this Agreement shall be barred unless commenced
within one (1) year after any such default occurs.

         (j)      Notwithstanding any provision to the contrary herein, or in
any of the documents evidencing the Obligations or otherwise relating thereto,
no such provision shall require the payment or permit the collection of interest
in excess of the maximum permitted by applicable usury laws. If any such
excessive interest is so provided for, then in such event: (i) the provisions of
this paragraph shall govern and control; (ii) neither the Debtor nor its heirs,
legal representatives, successors or assigns or any other party liable for the
payment thereof shall be obligated to pay the amount of such interest to the
extent that it is in excess of the maximum amount permitted by law; (iii) any
such excess interest that may have been collected shall be, at the option of the
holder of the instrument evidencing the Obligations, either applied as a credit
against the unpaid principal amount thereof or refunded to the maker thereof;
and (iv) the effective rate of interest shall be automatically reduced to the
maximum lawful rate under applicable usury laws as now or hereafter construed by
the courts having jurisdiction.

         (k)      The relationship between Debtor and Lender is solely of debtor
and creditor, and Lender has no fiduciary or other special relationship with
Debtor, and no term or provision of any of the Loan documents evidencing the
Obligations shall be construed so as to deem the relationship between the
parties to be other than that of debtor and creditor.

         (l)      THIS AGREEMENT AND THE NOTES AND SUPPLEMENTS SHALL BE GOVERNED
BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE
STATE OF NEW YORK. DEBTOR HEREBY IRREVOCABLY CONSENTS AND AGREES THAT ANY LEGAL
ACTION RELATING TO ANY LOAN DOCUMENT MAY BE INSTITUTED IN THE COURTS OF THE
STATE OF CALIFORNIA, IN THE COUNTY OF LOS ANGELES OR THE UNITED STATES COURTS
FOR THE SOUTHERN DISTRICT OF CALIFORNIA, AS LENDER MAY ELECT, AND BY EXECUTION
AND DELIVERY OF THIS AGREEMENT, DEBTOR HEREBY IRREVOCABLY ACCEPTS AND SUBMITS
TO, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, THE NON-EXCLUSIVE JURISDICTION OF
ANY SUCH COURT, AND TO ALL PROCEEDINGS IN SUCH COURTS. DEBTOR AND LENDER
ACKNOWLEDGE THAT JURY TRIALS OFTEN ENTAIL ADDITIONAL EXPENSES AND DELAYS NOT
OCCASIONED BY NONJURY TRIALS. DEBTOR AND LENDER AGREE AND STIPULATE THAT A FAIR
TRIAL MAY BE HAD BEFORE A STATE OR FEDERAL JUDGE BY MEANS OF A BENCH TRIAL
WITHOUT A JURY. IN VIEW OF THE FOREGOING, AND AS A SPECIFICALLY NEGOTIATED
PROVISION OF THIS AGREEMENT, DEBTOR AND LENDER HEREBY EXPRESSLY WAIVE ANY RIGHT
TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER
THIS AGREEMENT, THE NOTES AND SUPPLEMENTS OR THE TRANSACTIONS RELATED HERETO,
WHETHER NOW EXISTING OR


Loan and Security Agreement                                        Page 11 of 12

HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE; AND
DEBTOR AND LENDER HEREBY AGREE AND CONSENT THAT DEBTOR OR LENDER MAY FILE AN
ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN
EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO
TRIAL BY JURY.

                  IN WITNESS WHEREOF, the parties have caused this Agreement to
be duly executed and delivered by their duly authorized officers.
