ITEM 5.   OTHER EVENTS

          On May 15, 1998, Nord Resources Corporation (the "Company") received
     from the Overseas Private Investment Corporation ("OPIC") the balance of
     the proceeds from the civil strife insurance policy owned by the Company
     related to its 50% ownership in Sierra Rutile Limited ("SRL").  The Company
     received the $15,704,500 maximum amount allowed under the policy less
     $1,500,000 already received.  $5,627,429 of the proceeds was advanced by 
     the Company to SRL to be used, together with an equal amount advanced to 
     SRL by Consolidated Rutile Limited ("CRL"), the other 50% owner of SRL, 
     to reduce the existing indebtedness to SRL's development bank lenders (the 
     "Lenders"), $5,513,047 was deposited into a collateral account as 
     security for the scheduled September 30, 1998 payment by SRL to its 
     Lenders and $3,064,024 remains available for general corporate purposes.

          Concurrently with the receipt of the insurance proceeds and the
     related payment to the Lenders, SRL's debt agreements were amended.  The 
     Company is a 50% guarantor under these agreements.  The amendments provide 
     for a reduction in the interest rate SRL pays on its indebtedness to 
     6.875%, and the accrual of interest from May 15, 1998 to September 30, 
     1998 on most of the indebtedness rather than the current payment of such 
     interest and reschedule of the payments of principal and accrued and 
     unpaid interest.  Pursuant to such amendments, SRL is scheduled to pay 
     $11,506,562 ($5,753,281 guaranteed by the Company) on September 30, 1998 
     with the remaining $12,107,466 ($6,053,733 guaranteed by the Company) 
     payable 25% on September 30, 1999, 25% on September 30, 2000 and 50% on 
     September 30, 2001 in each case plus then current interest.  The stock 
     of SRL has been pledged to the Lenders as additional collateral for the 
     indebtedness to Lenders.

1.   We refer to our Loan Agreement with you dated 24th January 1992 as amended
to date (capitalized terms used and not otherwise defined herein shall have the
meanings ascribed thereto in the Loan Agreement). The outstanding principal
amount of our loan to you is US$6,976,665.64 (not including any payment made
today). Before expiration of our 15th December 1995 forbearance letter, as
amended and in effect through 15th May 1998, you have asked that we amend the
Loan Agreement as follows:


     AMENDMENT NO. 1:


     Section 5 of the Loan Agreement would read in its entirety as follows:


     "SECTION 5 - INTEREST


     5.1  The Borrower shall pay interest at the rate of six point eight seven
          five percent (6.875%) per annum on the principal amount of the CDC
          Loan disbursed and outstanding from time to time.  Interest for the
          period from 16th May 1998 through 30th September 1998 shall accrue and
          be added to the principal amount of the CDC Loan after the principal
          repayment on 30th September 1998.  Thereafter, interest shall be paid
          annually in arrears in US dollars on 30th September in each year.


     5.2  Without prejudice to the provisions of Clause 8.1, any interest
          falling due under this Agreement (including any further interest under
          this present provision) which is not paid within seven days of its due
          date shall itself bear interest (as well after as before judgment)
          from the date when it should have been paid until the date when it is
          actually paid at the rate of six point eight seven five percent
          (6.875%) per annum.

     5.3  Interest shall accrue and be prorated on the basis of a 360-day year
          for the actual number of days in the relevant interest period."


     AMENDMENT NO. 2:


     Section 7 of the Loan Agreement would read in its entirety as follows:

               notice during which time Nord and/or CRL may cure such occurrence
               unless, in CDC's opinion, it would be harmed by any such delay.

     2.   We agree to your requested amendments and to waive any breaches by the
     Borrower of this Agreement which arose before May 15, 1998 from the rebel
     incursion and occupation of the SRL minesite on 19th/20th January 1995 and
     the subsequent discontinuance of operations there or the 25th May 1997
     military coup and subsequent political events in Sierra Leone.  Theses
     amendments will be effective when:

               (i)    you execute and Nord and CRL acknowledge this amendment
                      agreement as provided below;

               (ii)   each other Senior Lender agrees to similar amendments to
                      its own loan agreement on similar conditions;

               (iii)  the Senior Lenders receive the executed documents
                      referred to Clause 8.1.2(b) of Amendment 3 above in form
                      and substance satisfactory to them;

               (iv)   OPIC insurance proceeds in an amount of not less than
                      US$5,500,000 have been deposited with Chase Manhattan
                      Bank pursuant to the Account Security and Control
                      Agreement referred to above; and

               (v)    you deliver legal opinions from counsel satisfactory to

          the security following an Event of Default, DEG shall use reasonable
          efforts to give the BORROWER and the Sponsors at least 10 business
          days' notice during which time the Sponsors may cure such Event of

          delay.  DEG agrees not to exercise any of its rights under the
          security documents or in respect of the security unless an Event of
          Default has occurred."

                        ACCOUNT CONTROL AND SECURITY AGREEMENT


     ACCOUNT CONTROL AND SECURITY AGREEMENT, dated as of May 15, 1998 (this
"AGREEMENT"), by and among NORD RESOURCES CORPORATION, a corporation organized
and existing under the laws of the State of Delaware (the "PLEDGOR"), THE CHASE
MANHATTAN BANK, a New York State chartered bank, as securities intermediary (in
such capacity, together with its successors and assigns, the "SECURITIES
INTERMEDIARY"), the OVERSEAS PRIVATE INVESTMENT CORPORATION, an agency of the
United States of America ("OPIC"), COMMONWEALTH DEVELOPMENT CORPORATION ("CDC"),
DEG - DEUTSCHE INVESTITIONS UND ENTWICKLUNGSGESELLSCHAFT MBH ("DEG"),
EXPORT-IMPORT BANK OF THE UNITED STATES ("EX-IM"), and INTERNATIONAL FINANCE
CORPORATION ("IFC" and together with OPIC, CDC, DEG and Ex-Im, the "BANKS").



                                PRELIMINARY STATEMENTS

     (1)    The Banks and the Pledgor entered into a Pledge, Assignment and
Security Agreement, dated as of February 28, 1996, as amended by a First
Amendment to Pledge Assignment and Security Agreement dated March 31, 1998 (as
the same may be further amended from time to time, the "PLEDGE AGREEMENT"),
pursuant to which the Pledgor pledged and assigned to the Banks all of its
right, title and interest in and to its rights to receive all but
US$4,564,024.27 of amounts payable under or in connection with OPIC Contract of
Insurance No. A628 and any extensions or renewals thereof or substitutions
therefor (the "OPIC Contract"), entered into by and between OPIC, as insurer,
and the Assignor, together with all proceeds thereof (collectively, the "Excess
Proceeds") as security for the Pledgor's obligations under(i) its Guaranty dated
as of February 28, 1996 (as the same may be amended from time to time, the
"GUARANTY") made for the benefit of the Banks, and (ii) to the extent the
Pledgor may have any obligations thereunder, the First Amendment and Restatement
of Project Funds Agreement dated as of November 17, 1992, (the "PFA") among,
INTER ALIA, the Pledgor and the Banks (the "LIABILITIES").

     (2)    The Pledge Agreement provides, INTER ALIA, that, so long as no
Default (as defined in the Pledge Agreement) shall have occurred and be
continuing, the parties thereto will use best efforts to appoint a collateral
agent to hold the Excess Proceeds on behalf of the Banks as security for the
Liabilities.

                                         -2-


     (3)    Each of the Banks has entered into a waiver and amendment agreement
dated as of May 15, 1998 (collectively, the "WAIVER AND AMENDMENT AGREEMENTS"),
pursuant to which the Banks have agreed to reschedule, and to waive certain
defaults with respect to, the payment obligations guaranteed under the Guaranty,
and to apply a portion of the Excess Proceeds to such payment obligations.

     (4)    It is a condition precedent to the effectiveness of the Waiver and
Amendment Agreements that the Pledgor shall have made the pledge and assignment
contemplated by this Agreement, which the Pledgor has agreed to do to induce the
Banks to enter into such Waiver and Amendment Agreements.

     NOW, THEREFORE, in consideration of the premises and in order to induce the
Banks to enter into the Waiver and Amendment Agreements, the parties hereto
hereby agree as follows:

     SECTION 1.  ASSIGNMENT.  The Pledgor hereby pledges and assigns to the
Banks, and hereby grants to the Banks a security interest in, all of its right,
title, and interest in and to the portion of the Excess Proceeds referenced to
in Section 4 below together with all interest, dividends and other income
thereon and proceeds thereof including, without limitation, the following,
whether now owned or hereafter acquired (collectively, the "COLLATERAL"):

     (i)    account no. E-00937, a non-interest bearing trust account
maintained by the Pledgor with the Securities Intermediary pursuant to Section
15(e) (the "SECURITIES ACCOUNT"), and all funds (including, without limitation,
that portion of the Excess Proceeds credited to such account as provided in
Section 4, and any other cash balances credited to such account), securities,
certificates, instruments, investment property, and all other property and
assets constituting financial assets from time to time held therein or required
to be deposited therein by the Pledgor and all other rights of the Pledgor in
and arising out of such account

     (ii)   all assets of whatever type or kind (whether or not such asset is a
Permitted Investment as hereinafter defined), placed or to be place in the
Securities Account, including all securities, investment securities,
instruments, accounts, general intangibles, contract rights, chattel paper,
choses in action, deposit accounts, and certificates of deposit, and the
certificates, certificates of deposit, or other instruments or documents
(including depository receipts, if any) evidencing any of such assets, any
investments made therewith, and all dividends, interest, cash, or other income
on and all proceeds of any of the foregoing now owned or hereafter acquired by
the Pledgor;

     (iii)  all proceeds of any and all of the foregoing Collateral and all
rights and privileges pertaining thereto (including, without limitation, any
proceeds derived from the sale, conversion, exchange, exercise, payment, or
liquidation


<PAGE>

                                         -3-


thereof, any funds or payments received from any reinvestment of such proceeds
in whatever form the same may be, and proceeds which constitute property of the
types described in clauses (i) and (ii) of this Section 1) and, to the extent
not otherwise included, any indemnity, warranty or guaranty, payable by reason
of loss or damage to or otherwise with respect to any of the foregoing
Collateral and cash.

     SECTION 2.  SECURITY FOR OBLIGATIONS.  The pledge, assignment, and grant in
this Agreement is made by the Pledgor to the Banks to secure:  (a) the payment
in full when due of all obligations and liabilities, whether contingent or
otherwise, of the Pledgor now or hereafter existing under the Guaranty and, to
the extent the Pledgor may have any obligations thereunder, the PFA, whether for
principal, interest, premium, indemnity amounts, fees, expenses, or otherwise,
including, without limitation, all obligations of the Pledgor now or hereafter
existing under this Agreement; (b) the performance by the Pledgor of all of its
obligations and liabilities to the Banks under the Guaranty and, to the extent
the Pledgor may have any obligations thereunder, the PFA; and (c) in the event
of any proceeding for the collection or enforcement of any indebtedness,
obligations, or liabilities referred to in clauses (a) and (b) above, the
reasonable expenses of retaking, holding, preparing for sale or lease, selling,
or otherwise disposing of or realizing on the Collateral, together with
attorneys' fees and court costs (all such obligations, liabilities, sums, and
expenses of the Pledgor set forth in clauses (a) through (c) above being herein
collectively called the "OBLIGATIONS").  Without limiting the generality of the
foregoing, this Agreement secures the payment of all amounts which constitute
part of the Obligations and would be owed by the Pledgor to the Banks but for
the fact that they are unenforceable or not allowable due to the existence of a
bankruptcy, reorganization, or similar proceeding involving the Pledgor.

     SECTION 3.  WAIVER.   The Pledgor hereby waives demand, notice, protest,
notice of acceptance of this Agreement, Collateral received or delivered, or
other action taken in reliance hereon, all demands and notices in connection
with the delivery, acceptance, performance, default, or enforcement of any of
the Obligations for which any of the Collateral is pledged and all other demands
and notices of any description, and assents to any extension or postponement of
the time of payment or any other indulgence, to any substitution, exchange, or
release of Collateral, or to the addition or release of any Person primarily or
secondarily liable.

     SECTION 4.  DELIVERY OF PLEDGED COLLATERAL.  Pursuant to a notice delivered
by the Banks to Overseas Private Investment Corporation, as insurer, (in such
capacity, the "INSURER") in the form attached hereto as Exhibit A, Excess
Proceeds in the amount of $5,513,046.56 shall be delivered by the Insurer to the
Securities Intermediary to be held in the Securities Account for the benefit of
the Banks as set forth herein.  Upon receipt of such Excess Proceeds, the
Securities Intermediary shall deliver to each of the Banks, with a copy to Nord,
a receipt in the form attached hereto as Exhibit B acknowledging such deposit.
All interest, dividends and other proceeds of the Collateral shall be deposited
in or otherwise


<PAGE>

                                         -4-


credited to the Securities Account by the Securities Intermediary.  All
certificates or instruments, if any, representing or evidencing the Collateral
shall be held in the Securities Account by the Securities Intermediary and
remain in its possession in the State of New York, shall be in suitable form for
transfer by delivery, or shall be accompanied by duly executed instruments of
transfer or assignment in blank, all in form and substance satisfactory to the
Banks.

     SECTION 5.  INVESTMENT OF COLLATERAL HELD IN SECURITIES ACCOUNT.

The Securities Intermediary shall invest all cash deposited or credited to the
Securities Account (including without limitation, the Excess Proceeds and any
interest, dividends or other proceeds of the Collateral deposited in or
otherwise credited to the Securities Account pursuant to Section 4) in Dollar
denominated investments, consisting of (A) securities that, at the date of
investment, are direct obligations of, or obligations fully guaranteed or
insured by, the United States or any agency or instrumentality of the United
States having a maturity of not later than September 30, 1998, and (B) such
other short-term, liquid investments considered to be of high-grade investment
quality by the Pledgor as the Banks may approve in writing (any or all of such
investments referred to herein as "PERMITTED INVESTMENTS") pursuant to written
instruction from Pledgor or, after notice of default as provided in Section 11,
from the Banks.  The Excess Proceeds shall be invested initially as set forth on
Schedule 2 annexed hereto.  All Permitted Investments shall be registered in the
name of the Security Intermediary for the benefit of the Banks pursuant to this
Agreement.  The Banks irrevocably instruct the Securities Intermediary with
respect to any Federal Book-Entry Securities constituting part of the
Collateral, to continuously (a) maintain, or cause or direct to be maintained,
such Collateral in the records of the Federal Reserve Bank of New York for the
sole and exclusive account of the applicable securities intermediary, and
(b) identify, or cause or direct to be identified, on the books and records of
the applicable securities intermediary for the sole and exclusive benefit of the
Securities Intermediary and in the books and records of the Securities
Intermediary as being the property of, or subject to a pledge and security
interest in favor of, the Banks.

     SECTION 6.  DISPOSITION OF COLLATERAL HELD IN SECURITIES ACCOUNT.

     So long as no default shall have occurred and be continuing under the
Guaranty, amounts shall be disbursed from the Securities Account as follow:

A    Unless the Securities Intermediary has received contrary instructions from
     the Banks, the Securities Intermediary shall disburse from the Securities
     Account to each of the Banks on September 30, 1998, the respective amount
     set forth next to its name on the attached Exhibit C.  The Banks agree to
     apply such amounts to the obligations of SRL guaranteed by the Pledgor
     under the Guaranty coming due on


<PAGE>

                                         -5-


     September 30, 1998 pursuant to the Waiver and Amendment Agreements.  For
     purposes of such disbursement, the Excess Proceeds shall not constitute
     "Distribution Moneys" as such term is defined in the Security Sharing and
     Intercreditor Agreement dated as of November 17, 1993, among the Banks and
     Sierra Rutile Limited, a corporation organized and existing under the laws
     of Sierra Leone and indirectly 50% owned by the Pledgor ("SRL").  In the
     event the Collateral, after liquidation of all Permitted Investments, is
     not sufficient to make such payments in full on such date, each payment
     shall instead be made in proportion to Pro-Rata Share (as set forth on
     Exhibit C).

B    In the event the Banks receive a notice of prepayment concerning the
     Obligations, the Banks agree, at the request of the Pledgor, to issue a
     notice of prepayment to the Securities Intermediary directing that the
     Securities Intermediary disburse to the Banks from the Securities Account
     on the prepayment date the amount specified by the Pledgor in its request
     to the Banks, and the Securities Intermediary shall disburse to each Bank a
     percentage of such amount equal to the respective percentage set forth next
     to its name on the attached Exhibit C (such percentage, its "PRO RATA
     SHARE").


C    The Securities Intermediary shall take any other action with respect to
     disbursements from the Securities Account pursuant to written instructions
     from the Banks.


D    Upon notice from the Banks that the Obligations have been paid in full, the
     Securities Intermediary shall disburse any balance remaining in the
     Securities Account to or at the direction of the Pledgor.


     SECTION 7.  REPRESENTATIONS AND WARRANTIES.  The Pledgor represents and
warrants as follows:

     (a)    It has established the Securities Account with the Securities
Intermediary.

     (b)    The Collateral held by it or on its behalf shall be fully paid and
nonassessable, and all documentary, stamp, or other taxes or fees that may be
owing in connection with the issuance, transfer, and pledge thereof hereunder
shall have been paid by it or on its behalf.


<PAGE>

                                         -6-


     (c)    This Agreement creates a valid security interest in the Collateral
purported to be pledged and assigned by the Pledgor hereunder securing the
payment of the Obligations.

     (d)    Each item of Collateral held in the Securities Account constitutes
a "security entitlement" (as defined in Article 8 of the Uniform Commercial Code
as in effect in the State of New York (the "UCC")); all of such Collateral is
located in the State of New York; the security interest created by this
Agreement in the Securities Account and such Collateral is perfected under the
UCC, and such security interest, as so perfected, is first priority.

     (e)    The Pledgor is the legal and beneficial owner of and has good title
to the Collateral purported to be pledged and assigned by it hereunder, free and
clear of any lien thereon, other than the lien created under the Pledge
Agreement .  No effective financing statement or other instrument similar in
effect covering all or any part of such Collateral is on file in any recording
office, except such as may have been filed in favor of the Banks relating to
this Agreement.

     (f)    The Permitted Investments, when deposited into the Securities
Account, will constitute "financial assets", as defined in Article 8 of the UCC.

     (g)    The Pledgor is not a party to any agreement with respect to the
establishment, management, or operation of the Securities Account or investment
of amounts deposited or held therein, except for this Agreement.

     (h)    The Banks have sole "control" (as defined in Article 8 of the UCC)
of the Securities Account and the financial assets held therein.

     (i)    The Pledgor has neither (i) borrowed any money from, (ii) been
extended any credit by, nor (iii) become otherwise obligated to pay any money
to, the Securities Intermediary, other than the fees or expenses payable to the
Securities Intermediary pursuant to Section 12(b).

     (j)    There are no conditions precedent to the effectiveness of this
Agreement that have not been satisfied or waived;

     (k)    This Agreement has been duly and validly authorized by the Pledgor,
is binding and enforceable against the Pledgor in accordance with its terms,
does not violate any provision of any law, rule, regulation, order, judgment or
decree applicable to Pledgor, and no consent of any other party is necessary to
accomplish the pledge, assignment and grant of security interest contemplated
hereby

     (l)    The Pledgor is now, and after execution and delivery of this
Agreement will continue to be, solvent and no bankruptcy or insolvency
proceedings are pending or contemplated by or against the Pledgor


<PAGE>

                                         -7-


     SECTION 8.  FURTHER ASSURANCES.  (a)  The Pledgor agrees that from time to
time, at its expense, it will promptly execute and deliver all further
instruments and documents, and take all further action, that may be necessary or
desirable, or that the Banks may request, in order to perfect, protect, and
preserve the pledge, assignment, and security interest granted or purported to
be granted hereby or to enable the Banks to exercise and enforce their rights
and remedies hereunder with respect to any Collateral.  Without limiting the
generality of the foregoing, the Pledgor will execute and file such assignments,
certificates, supplemental writings, financing or (at the request of the Banks)
continuation statements, or amendments thereto, and such other instruments or
notices, and do all other acts and things, as may be necessary or desirable, or
as the Banks may request, in order to evidence more fully and perfect and
preserve the pledge, assignment and security interest granted or purported to be
granted hereby.

     (b)    The Pledgor hereby further authorizes the Banks to file one or more
financing or continuation statements, and amendments thereto (any such financing
or continuation statements or amendments to be delivered by the Pledgor to the
Banks in form sufficient for filing and with instructions for filing thereof),
relating to all or any part of the Collateral without the signature of the
Pledgor where permitted by law.  A photographic or other reproduction of this
Agreement or any financing statement covering the Collateral or any part thereof
shall be sufficient as a financing statement where permitted by law.

     (c)    The Pledgor will furnish to the Banks from time to time, and no
less than once every fiscal quarter of each Fiscal Year of the Pledgor,
statements and schedules further identifying and describing the Collateral and
such other reports in connection with the Collateral as the Banks may reasonably
request, all in reasonable detail.


     SECTION 9.  COVENANTS.  The Pledgor covenants and agrees that, so long as
any of the Obligations shall remain unpaid, unless the Banks shall otherwise
consent in writing, the Pledgor will:

     (a)    not make any withdrawal from or direct that any payment be debited
from the Securities Account other than as expressly permitted by this Agreement;

     (b)    not permit any Person other than the Banks to have "control" (as
defined in Article 8 of the UCC) of the Securities Account or any of the
financial assets held therein, including, without limitation, as a result of the
grant of a security interest in any such Securities Account or assets to the
Chase Manhattan Bank or any other Person acting as securities intermediary with
respect to such Securities Account and assets;


<PAGE>

                                         -8-


     (c)    pay all documentary, stamp, registration, or other taxes or fees,
if any, to which this Agreement may be subject or give rise, and to indemnify
the Banks against any and all liabilities with respect to or resulting from any
delay or omission on the part of the Pledgor to pay any such duties, taxes, or
fees;

     (d)    not (i) borrow any money from, (ii) allow any credit to be extended
to it by, or (iii) become otherwise obligated to pay any money to, the
Securities Intermediary, other than the fees or expenses payable to the
Securities Intermediary pursuant to Section 12(b); and

     (e)    not take any action in connection with the Collateral that would
materially impair the value of the Collateral or that would impair the interest
or rights of the Banks therein.

     SECTION 10.  BANKS MAY PERFORM.  If the Pledgor fails to perform any
agreement contained herein, the Banks, or any of them, may perform, or cause
performance of, such agreement, and the expenses of the Banks incurred in
connection therewith shall be payable by the Pledgor under Section 12(b).


     SECTION 11.  REMEDIES.  If any default under the Guaranty shall have
occurred and be continuing:

     (a)    The Banks, and each of them, shall be entitled to exercise all of
the rights, powers and remedies (whether vested in them by this Agreement, by
law, in equity, by statute or otherwise), to the maximum extent permitted by
applicable law, for the protection and enforcement of their rights in respect of
the Collateral, and to exercise the following rights to the maximum extent
permitted by applicable law:

            (i)     to have and exercise all of the rights and remedies with
respect to the Collateral of a pledgeholder or a secured party under the UCC,
and such additional rights and remedies to which a pledgeholder or secured party
is entitled under the laws in effect in any jurisdiction where any rights and
remedies hereunder may be asserted, including, without limitation, the right to
exercise all powers of ownership pertaining to the Collateral (whether or not
transferred into the name of the Banks) as if the Banks were the sole and
absolute owner thereof;

            (ii)    to direct the Securities Intermediary to transfer such
Bank's Pro Rata Share of the Collateral from the Securities Account to, or to
the account of, such Bank.  Upon receipt of any such instruction from any Bank,
the Securities Intermediary shall notify each other Bank thereof, and shall
transfer to such Bank its Pro Rata Share of the Collateral in accordance with
wiring instructions delivered by such Bank to the Securities Intermediary.  Upon
any such transfer to a 


<PAGE>

                                         -9-


Bank, such Bank's Pro Rata Share of the Collateral shall be reduced to zero,
and the  Pro Rata Shares of the other Banks with respect to the remaining
Collateral shall be adjusted accordingly.


     SECTION 12.  CONCERNING THE SECURITIES INTERMEDIARY.

     (a)    POWERS OF THE SECURITIES INTERMEDIARY.  The Pledgor and each of the
Banks hereby designates and appoints The Chase Manhattan Bank as Securities
Intermediary and agrees that the Securities Intermediary shall exercise such
powers under this Agreement as are delegated to the Securities Intermediary by
the terms hereof.  The Chase Manhattan Bank hereby agrees to act as Securities
Intermediary upon the express terms and conditions contained in this Agreement.

     (b)    COMPENSATION AND REIMBURSEMENT OF SECURITIES INTERMEDIARY.  (i)
The Pledgor upon execution hereof shall pay the Securities Intermediary the fees
payable pursuant to Schedule I hereto.

            (ii)    The Pledgor shall reimburse the Securities Intermediary upon
request for all expenses, disbursements, and advances incurred or made by the
Securities Intermediary in implementing any of the provisions of this Agreement,
including, without limitation, compensation and the expenses and disbursements
of its counsel and agents, except any such expense, disbursement, or advance as
may arise from its gross negligence or willful misconduct.

            (iii)   The Securities Intermediary shall promptly notify the Banks
of any failure by the Pledgor to pay the Securities Intermediary for any fees
and expenses due and payable to the Securities Intermediary pursuant to this
Section 12(b).

     (c)    SECURITIES INTERMEDIARY'S WAIVER OF LIEN ON COLLATERAL.  The

            (iii)   The Securities Intermediary shall not be liable hereunder
except for its own gross negligence or willful misconduct and the Pledgor agrees
to indemnify the Securities Intermediary and any predecessor securities
intermediary for and hold it harmless as to any and all documented loss,
liability, claim, damage, or expense, including, without limitation, taxes other
than taxes based on the income of the Securities Intermediary and reasonable
attorney's fees and expenses, incurred without gross negligence or willful
misconduct on the part of the Securities Intermediary and arising out of or in
connection with the Securities Intermediary's duties under this Agreement.
Anything in this agreement to the contrary notwithstanding, in no event shall
the Securities Intermediary be liable for special, indirect or consequential
loss or damage of any kind whatsoever (including but not limited to lost
profits), even if the Securities Intermediary has been advised of the likelihood
of such loss or damage and regardless of the form of action.  Specifically and
without limiting the foregoing, the Securities Intermediary shall in no event
have any liability in connection with its investment, reinvestment or
liquidation, in good faith and in accordance with the terms hereof, of any
Collateral held by it hereunder, including, without limitation, any liability
for any delay not resulting from gross negligence or willful misconduct in such
investment, reinvestment or liquidation, or for any loss of income incident to
any such delay.  The Securities Intermediary shall have the right to liquidate
any investments held, in order to provide funds necessary to make required
payments under this Agreement.  The Securities Intermediary in its capacity as

a result of any liquidation of any investment prior to its maturity or for the
failure of the parties to give the Securities Intermediary instructions to
invest or reinvest fund or any earnings thereon.

            (iv)    In no event shall the Securities Intermediary be liable (A)
for acting in accordance with entitlement orders or other instructions,
directions, or requests from the Banks or (B) for special or consequential
damages.

            (v)     The Securities Intermediary shall be entitled to
conclusively rely upon any order, judgment, certification, instruction, notice,
opinion, or other writing delivered to it in compliance with the provisions of
this Agreement without being required to determine the authenticity or the
correctness of any fact stated therein or the propriety or validity of service
thereof.  The Securities Intermediary may act in reliance upon any instrument
comporting with the provisions of this Agreement or signature believed by it to
be genuine and may assume that any Person purporting to give notice or receipt
or advice or make any statement or execute any document in connection with the
provisions hereof has been duly authorized to do so.

            (vi) At any time the Securities Intermediary may request in writing
an instruction in writing from the Banks, the Securities Intermediary may at its
own option include in such request the course of action it proposes to take and
the date on which it proposes to act, regarding any matter arising in connection
with its duties and obligations hereunder.  The Securities Intermediary shall
not be liable for acting without the Banks' consent in accordance with such a
proposal on or after the date specified therein, provided that the specified
date shall be at least two (2) Business Days after the Banks receive the
Securities Intermediary's request for instructions and its proposed course of
action, and provided further that, prior to so acting, the Securities
Intermediary has not received the written instructions requested.

            (vii)   The Securities Intermediary does not have any interest in
the Collateral deposited hereunder but is serving only as securities
intermediary under the Securities Account and has only possession thereof.

            (viii)   The Securities Intermediary makes no representation as to
the validity, value, genuineness or collectability of any security or other
document or instrument held by or delivered to it.

            (ix)    The Securities Intermediary shall not be called upon to
advise any party as to selling or retaining, or taking or refraining from taking
any action with respect to, any securities or other property and assets
deposited hereunder.

            (x)     No provision of this Agreement shall require the Securities
Intermediary to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties, or in the exercise of any of
its rights or powers, hereunder.

            (xi)    For purposes of the duties of the Securities Intermediary
hereunder a default shall occur or be deemed to occur when the Securities
Intermediary shall have received a written notice from any Bank so stating.

            (xii)   The provisions of this Section 12 shall survive termination
of this Agreement and/or the closing of the Securities Account by the Securities
Intermediary.

remedies given by applicable law, the Guaranty, or any other document or

other rights, powers and remedies, including, without limitation, any other
rights of setoff, or rights under any other document or agreement, and, in like
manner, the exercise by the Banks, or any of them, of any right, power or remedy
under applicable law or another document or agreement shall not diminish or

assignment of, and security interest in, the Collateral and shall remain in full
force and effect until the Obligations shall have been indefeasibly paid in full
in Dollars and (ii) be binding upon the Pledgor, its successors and permitted
assigns.  Upon the indefeasible payment in full in Dollars of the Obligations,
the security interest granted hereby shall terminate and all rights to the
Collateral shall revert to the Pledgor.  Upon any such termination, the Banks
will, at the Pledgor's expense, execute and deliver to the Pledgor and the
Securities Intermediary such documents as the Pledgor and Securities
Intermediary shall reasonably request to evidence such termination.

     (b)    To the extent that any payments on the Obligations or proceeds of
the Collateral are subsequently invalidated, declared to be fraudulent or
preferential, set aside or required to be repaid to a trustee, debtor in

revived and continue as if such payment or proceeds had not been received by the

     SECTION 18.  WAIVER OF JURY TRIAL.  THE PLEDGOR, THE SECURITIES
INTERMEDIARY, AND THE BANKS HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT
PERMITTED BY LAW, ANY RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE

DOCUMENT, OR AGREEMENT ENTERED INTO IN CONNECTION WITH THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

     SECTION 19.  JURISDICTION AND CONSENT TO SUIT  (a)  Without prejudice to

Pledgor may be found.  The Pledgor hereby irrevocably waives any present or
future objection to any such venue, and irrevocably and unconditionally consents
and submits, for itself and in respect of any of its property, to the
nonexclusive jurisdiction of any such court.  Final judgment against the Pledgor
in any action or proceeding arising out of or relating to this Agreement shall
be conclusive and may be enforced in any other jurisdiction within or outside

obligations.

     (b)    The Pledgor irrevocably designate and appoint Spitzer & Feldman PC
as agent for service of process in the State of New York as its authorized agent
to receive, accept, and acknowledge on its behalf service of process in any
proceeding and has provided the Banks and the Securities Intermediary with
evidence of the prepayment in full of the fees of such agent.  The Pledgor
agrees that service of process, writ, judgment, or other notice of legal process
upon said agent shall be deemed and held in every respect to be effective
personal service upon it.  The Pledgor shall maintain such appointment (or that
of a successor satisfactory to the Banks) continuously in effect at all times
while the Pledgor is obligated under this Agreement.  Nothing herein shall
affect any Bank's right to serve process in any other manner permitted by
applicable law.

     SECTION 20.  MISCELLANEOUS

     (a)    The Securities Intermediary shall not be liable for any action
taken or omitted by it in good faith unless a court of competent jurisdiction
determines that the Securities Intermediary's willful misconduct was the primary
cause of any loss to the parties hereto.  In the administration of the account
hereunder, the Securities Intermediary may execute any of its powers and perform
its duties hereunder directly or through agents or attorneys and may, consult
with counsel, accountants and other skilled persons to be selected and retained
by it.  The Securities Intermediary shall not be liable for anything done,
suffered or omitted in good faith by it in accordance with the advice or opinion

     (d)    In the event that the Securities Intermediary shall be uncertain as
to its duties or rights hereunder or shall receive instructions, claims or
demands from any party hereto which, in its opinion, conflict with any of the
provisions of this Agreement, it shall be entitled to refrain from taking any
action and its sole obligation shall be to keep safely all property held in

jurisdiction.

            (ii)    In the event funds transfer instructions are given (other
than in writing at the time of execution of the Agreement), whether in writing,
by telecopier or otherwise, the Securities Intermediary is authorized to seek
confirmation of such instructions by telephone call-back to the person or
persons designated on Schedule 2 hereto, and the Securities Intermediary may
rely upon the confirmations of anyone purporting to be the persons so
designated.  The persons and telephone numbers for call-backs may be changed
only in writing actually received and acknowledged by the Securities
Intermediary.  The parties to this Agreement acknowledge that such security
procedure is commercially reasonable.

to or upon the Shareholder or any other person (all of which are, to the extent
permitted by law, hereby expressly waived), forthwith realize upon the Mortgaged
Shares or any part thereof, and may forthwith, or may agree to, sell or
otherwise dispose of and deliver the Mortgaged Shares or any part thereof or
interest therein, in one or more portions at a private sale or sales, at such
prices and on such terms as it may deem best, for cash or on credit, or for
future delivery with or without assumption of any credit risk, with the right to
the Banks or any other purchaser to purchase upon any such sale the whole or any
part of the Mortgaged Shares free of any right or equity of redemption in the
Shareholder, which right or equity is hereby expressly waived and released.


     (b)  The proceeds of any such disposition or other action by the Banks
shall be applied as follows:


          (i)    first, to the costs and expenses incurred in connection
therewith or incidental thereto or to the care or safekeeping of any of the
Mortgaged Shares or in any way relating to the rights of the Banks hereunder,
including reasonable attorneys' fees and legal expenses;


          (ii)   second, to the satisfaction in full of the Obligations;


          (iii)  third, to the payment of any other amounts required by
applicable law; and


          (iv)   fourth, to the Shareholder to the extent of any surplus

hereunder without any other notice and without compliance with any other
condition precedent now or hereafter imposed by statute, rule of law or
otherwise (all of which are hereby expressly waived by the Shareholder, to the
fullest extent permitted by law).

     (d)  The Banks shall not be obligated to make any sale of the Mortgaged
Shares if it shall determine not to do so, regardless of the fact that notice of
sale of the Mortgaged Shares shall have been given.  The Banks may, without
notice or publication, adjourn any private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for the
sale, and such sale may be made at the time and place to which the same was
adjourned.  The Shareholder acknowledges that any private sale shall be deemed
to have been made in a commercially reasonable manner.

<PAGE>
                              COLLATERAL AGENT AGREEMENT




          This Collateral Agent Agreement ("Collateral Agent Agreement") dated
as of May 15, 1998 by and among COMMONWEALTH DEVELOPMENT CORPORATION ("CDC"),
DEG-DEUTSCHE INVESTITIONS UND ENTWICKLUNGSGESELLSCHAFT MBH ("DEG"),
EXPORT-IMPORT BANK OF THE UNITED STATES ("Ex-Im"), INTERNATIONAL FINANCE
CORPORATION ("IFC") and OVERSEAS PRIVATE INVESTMENT CORPORATION ("OPIC";
collectively "Development Banks"), and SIERRA RUTILE HOLDINGS LIMITED
("Holdings") and CHASE MANHATTAN BANK ("Collateral Agent").

          WHEREAS, Holdings owns 38,685,017 ordinary shares ("Shares") of Sierra
Rutile Limited ("SRL"), representing 100% of the issued and outstanding shares
of SRL; and

          WHEREAS, the Development Banks have made certain loans to SRL pursuant
to various loan agreements, as amended ("Loan Agreements"); and

          WHEREAS, Holdings has executed a Stock Pledge Agreement ("Pledge
Agreement"), pledging the SRL Shares to the Development Banks; and

          WHEREAS, the Development Banks and Holdings have agreed that
Collateral Agent shall act as the collateral agent pursuant to the Pledge
Agreement; and

          NOW, THEREFORE, it is hereby agreed as follows:
          
          1.   DESIGNATION OF COLLATERAL AGENT.   Development Banks hereby
designate and appoint Collateral Agent as Collateral Agent to serve in
accordance with the terms of this Collateral Agent Agreement.  The Collateral
Agent hereby accepts such appointment and agrees to act as Collateral Agent
pursuant to the terms and conditions of this Collateral Agent Agreement. 

          2.   ACKNOWLEDGEMENT OF RECEIPT.   The Collateral Agent hereby
acknowledges receipt of the certificates representing the Shares, copies of
which are annexed hereto as Exhibit A together with stock Transfer thereof
("Transfer") executed in blank, copies of which are annexed hereto as Exhibit B,
and agrees to hold and dispose of the Shares and Transfer in accordance with the
terms and conditions of this Collateral Agent Agreement and the Pledge
Agreement. 

          3.   DISPOSITION OF SHARES AND TRANSFER.     In the event that
Collateral Agent receives any notice jointly from the Development Banks
requesting that the Shares and Transfer be delivered either (a) to the
Development Banks or any of them or their designees or (b) to Holdings,
Collateral Agent shall promptly thereafter deliver the Shares in accordance with
such notice, provided, however, that if such notice requests delivery pursuant
to subdivision (a) above, the Collateral Agent shall give to Holdings five (5)
business days prior written notice thereof before 


<PAGE>

making such delivery, unless the Banks, in their notice notify the Collateral
Agent that (i) they would be harmed by waiting such period or (ii) such notice
has been waived by Holdings.

          4.   LIABILITY; INDEMNIFICATION.  (a) The parties hereto agree that
the duties of the Collateral Agent hereunder are purely ministerial in nature
and that the Collateral Agent shall incur no liability hereunder or otherwise
(except in the event of a final adjudication of willful misconduct or gross
negligence) for any action taken by it hereunder or for any failure or refusal
to act pursuant to any notice, direction or instructions which it may receive
from any party hereto or for any other matter.  The Collateral Agent shall be
under no responsibility with respect to the Shares and Transfer other than
faithfully to follow the instructions herein contained.  The Collateral Agent
shall have no responsibility to determine the authenticity or validity of any
notice, direction, instruction, document or other item delivered to it, and it
shall be fully relieved of any liability in acting in accordance with any
written notice, direction or instruction given to it under this Collateral Agent
Agreement and believed by it, in its subjective judgment, to be authentic.

          (b)  Unless the Collateral Agent shall have been finally adjudicated
guilty of willful misconduct or gross negligence, Holdings agrees to indemnify
and hold harmless the Collateral Agent from and against any liability incurred
by it hereunder including reasonable attorneys fees and expenses (which
obligation shall survive the closing of the Collateral Agent Agreement).  The
Collateral Agent shall not be required to defend any legal proceedings which may
be instituted against it with respect to the subject matter of this Collateral
Agent Agreement unless requested to do so by the Development Banks or Holdings
and indemnified to its satisfaction against the cost and expenses of such
defense.

          (c)  Anything in this Collateral Agent Agreement to the contrary
notwithstanding, in no event shall the Collateral Agent be liable for special,
indirect or consequential loss or damage of any kind whatsoever (including but
not limited to lost profits), even if the Collateral Agent has been advised of
the likelihood of such loss or damage and regardless of the form of action.

          5.   COMPENSATION OF COLLATERAL AGENT.  All compensation to Collateral
Agent shall be paid by Holdings to Collateral Agent in accordance with the terms
set forth on Schedule 1 annexed hereto, and Holdings and Collateral Agent agree
that the Development Banks shall not have any liability therefor.

          6.   TERMINATION OF AGREEMENT.  This Collateral Agent Agreement shall
terminate and the Collateral Agent shall be fully released and discharged from 
all obligation and liability hereunder, upon the delivery of the Shares and 
Transfer as provided herein.

          7.   NOTICES.  All notices, requests and other communications under
this Collateral Agent Agreement shall be in writing and shall be personally
delivered, sent by first class registered or certified mail, postage prepaid,
return receipt requested, or sent by United States Express Mail or overnight
