        Agreement.

             (c)     This Agreement is a Loan Document and shall be interpreted
        and construed in accordance with the terms and provisions of the Loan
        Agreement (including Sections 1.2 to 1.5 thereof which are hereby

severally irrevocably and unconditionally

             (a)     guarantee to each Lender Party the due and punctual
        observance and performance of all the Guaranteed Obligations and agree
        to pay to the Agent on demand the Guaranteed Obligations which shall not
        have been paid by the Borrower at the time such demand is made, and

             (b)     agree as a primary obligation to indemnify each Lender
        Party on demand by the Agent from and against any loss, damage, costs
        and outlays (including loss of profit) incurred by such Lender
        Party as a result of any of the Guaranteed Obligations

                                      -2-

        being or becoming void, voidable, unenforceable or ineffective as
        against the Borrower for any reason whatsoever, whether or not known to
        such Lender Party or any other person, the amount of such loss, damage,
        costs and outlays (including loss of profit) being the amount which such
        Lender Party would otherwise have been entitled to recover from the
        Borrower.

        SECTION 2.2. INSOLVENCY DEFAULT Each Guarantor agrees that, upon the
occurrence of an Insolvency Default at a time when any of the Guaranteed
Obligations may not then be due and payable, the Guarantors will pay to the
Agent (for the ratable benefit of the Lender Parties) forthwith the full amount
which would be payable pursuant to Section 2.1 if all such Guaranteed
Obligations were then due and payable.

        SECTION 2.3. PRINCIPAL DEBT As an original and independent obligation
under this Agreement, each of the Guarantors agree that if any of the Guaranteed
Obligations are or may not be recoverable from such Guarantor on the footing of
a guarantee or indemnity under Section 2.1, whether by reason of any legal
limitation on or incapacity of the Borrower or for any other reason whatsoever,
the Guaranteed Obligations will be recoverable from such Guarantor as though the
same had been incurred by such Guarantor as sole or principal debtor. Each of
the Guarantors agree that its obligation under this Section applies whether or
nor any such fact or circumstance was or could have been known to any Lender
Party.

herein contained shall be in addition to and independent of every other
security, guarantee or indemnity which any Lender Party may at any time hold in
respect of any of the Guaranteed Obligations.

herein contained shall constitute and be continuing obligations notwithstanding
any settlement of account or other matter or thing whatsoever, and in
particular, but without limitation, shall not be considered satisfied by any
intermediate payment or satisfaction of any of the Guaranteed Obligations and
shall continue in full force and effect, provided, however, that on and from the
Release Date each Guarantor's obligations pursuant to Section 2.1 shall be
limited to the proceeds of the Charged Property over which it has granted a
lien.

        SECTION 2.6. RIGHTS NOT AFFECTED Neither the obligations of the
Guarantors under this Agreement, nor the rights, powers or remedies conferred in

        this Agreement.

and, if any such security or payment is so avoided or reduced, such Lender Party
shall be entitled to recover the value or amount of such security or payment
from the Guarantors subsequently as if such settlement or discharge had not

rights of any Lender Party pursuant to Section 3, nor any monies received or
recovered by any Lender Party pursuant to this Section 2 or Section 3 shall
impair the right of such Lender Party to prove in such winding up, liquidation,
bankruptcy, composition or arrangement for the total amount due from the
Borrower or such other Guarantor and, to this end or so as to preserve intact
the obligations of any person answerable for any part of such total amount, any
Lender Party may at any time and after any such event takes place and, for so
long as such Lender Party thinks fit prior to satisfaction in full of each
Guarantor's obligations under this Agreement, keep any monies received or
recovered under this Agreement in a separate or suspense account, in such name
as such Lender Party thinks fit, without any intermediate obligation on the part
of such Lender Party to apply the same in or towards discharge of any part of
such total amount.

        SECTION 2.11.  RESERVE BANK RESTRICTIONS

        Guaranteed Obligations or any Guarantor shall have become obligated to
        make payment to the Agent pursuant to Section 2.2 because of the
        occurrence of an Insolvency Default, but, on the date of such demand or
        Insolvency Default (as the case may be) such Guarantor shall not then be
        permitted pursuant to the rules and regulations of the Reserve Bank of
        South Africa to make payments in Dollars pursuant to this Agreement then
        such Guarantor shall promptly (without prejudice to the provisions of
        Section 5.12 of the Loan Agreement)

                     (i)     deposit in a segregated cash collateral account in
             South Africa nominated by the Agent cash collateral in an amount
             equal to the Rand equivalent (determined by reference to the
             current Rand/Dollar market exchange rates quoted by Standard Bank
             London Limited) of the amount demanded by the Agent or payable
             pursuant to Section 2.1 or 2.2, and

                     (ii)    charge to the Agent (for the benefit of the Lender
             Parties) (x) such cash deposit and such segregated account together
             with all related rights and interests, and (y) the benefit of a
             currency forward sale agreement to be implemented by such Guarantor
             (subject to market availability) (with a counterparty acceptable to
             the Agent) and providing for the delivery of Dollars on such date
             as the Agent may select as the earliest estimated date on which it
             is reasonably practicable to obtain the permission of the Reserve
             Bank of South Africa contemplated in clause (a) (the "Deferred
             Payment Date") in an amount equal to the then outstanding
             Guaranteed Obligations in exchange for the delivery of Rand in an
             amount equal to the amount deposited by way of cash collateral
             pursuant to clause (a)(1). All arrangements referred to in the
             immediately preceding sentence shall be on terms and conditions,
             and shall be implemented pursuant to documentation, satisfactory to
             the Lender Parties.

             (b)     In the event that, following the selection of the Deferred
        Payment Date pursuant to the provisions of clause (a), the rules and
        regulations of the Reserve Bank of South Africa (or any other
        Governmental Agency of South Africa) shall permit such Guarantor to make
        payment of the Guaranteed Obligations in Dollars prior to the Deferred
        Payment Date then the Deferred Payment Date shall, immediately upon the

                                      -6-

<PAGE>

        obtaining by such Guarantor of any relevant Approval in connection with
        such permission, be deemed amended to occur on the third Business Day
        following the date of obtaining such Approval and such Guarantor hereby
        undertakes with the Lender Parties to take all such acts as may be
        necessary to obtain such Approval promptly upon the rules and
        regulations of the Reserve Bank of South Africa (or such other
        Governmental Agency) permitting such payment in Dollars to be made.

             (c)     Nothing in this Section shall prejudice the ability of the
        Lender Parties to obtain payment from the Borrower or any Guarantor or
        of all Liabilities as and when the same may become due.

                       SECTION 3. UNDERTAKINGS OF THE GUARANTORS

        labour, materials, supplies or equipment, from taxes, assessments, fees
        or other charges, from injuries or damage to persons or property, or
        otherwise.

             (c)     NATURE OF OBLIGATIONS:  Without limiting the generality of
        the foregoing provisions of this Section, the Guarantors agree, in
        relation to the performance of its obligations under this Agreement, to
        ensure that the costs of constructing the Mine and completing the Morila

        doubt, any such costs funded with the proceeds of Loans), the existence
        of which shall be

                                      -7-

        determined by the Agent (acting in consultation with the Independent
        Engineer), are funded, paid and satisfied from its own resources and to
        cause the installation and completion of the Morila Project in a timely,
        good, workmanlike and lien-free manner, in accordance with the Agreed

        contained in this Agreement (including clause (a) of Section 3.1,
        Section 3.2 and Section 3.3))

                     (i)     Mechanical Completion does not occur by 30 June,
             2001, or

                     (ii)    the Economic Completion Date does not occur by the
             earlier of 31 December, 2001 or 6 months after the Mechanical

                     (iii)   Economic Completion or Mechanical Completion is not
             achieved in accordance with the Agreed Project Standards then in
             such event or at any time thereafter, the Agent may give written
             notice thereof to the Guarantors and the following provisions shall
             then apply

                     (iv)    THE GUARANTORS TO STEP-IN: Within ten days after
             the date on which the Agent gives any such notice to the
             Guarantors, the Guarantors will, at their cost, commence to

             connection with such completion

                     (v)     THE GUARANTORS FAIL TO COMPLETE: If the Guarantors
             fail to complete the construction of the Mine or diligently to
             prosecute such construction in accordance with the Development
             Plan, then in addition to any other rights or remedies that may be
             available to the Lender Parties under this Agreement, the other
             Operative Documents, or at law or in equity (including the right
             and remedy of specific performance) the Lender Parties may either
             through the Agent (but only with the Agent's consent, which may be
             withheld in its absolute discretion) or through a nominee exercise
             any one or more of the following rights and remedies

                     (x)     without undertaking to complete the construction of
                             the Mine or being obliged to foreclose on or
                             enforce the security described in the Loan
                             Documents, the Lender Parties shall have the right
                             to recover damages from the Guarantors in an amount
                             equal to all costs which the Lender Parties would
                             have to incur in order to achieve Mechanical
                             Completion and Economic Completion in accordance
                             with the Agreed Project Standards and to reach the
                             Release Date, and/or

                                      -8-

<PAGE>

                     (y)     without undertaking to complete the construction of
                             the Morila Project, the Lender Parties, at their
                             option, shall have the right, but shall have no
                             obligation, to proceed or to direct the Agent to
                             proceed, as appropriate, to foreclose on or enforce
                             any of the security described in the Loan
                             Documents.

             (e)     CUMULATIVE REMEDIES:  The Lender Parties' remedy of
        specific performance, the recovery of damages and all other rights and
        remedies under this Agreement, and the other Operative Documents, at law
        or in equity are non-exclusive of each other and cumulative. The parties
        to this Agreement recognise that the choice of remedies made by the
        Lender Parties at any time will necessarily and properly be a matter of
        business judgment, which the passage of time or change of circumstances
        may or may not prove to have been the best choice to maximise recovery
        by the Lender Parties at the lowest cost to the Borrower or the
        Guarantors. Nevertheless, the choice of remedies by the Lender Parties
        shall not be subject to question or challenge by any other person, nor
        shall any such choice be asserted as a defence, set-off or basis for any
        claim of failure to mitigate loss on the part of the Lender Parties in
        any action or proceeding arising in connection with this Agreement.

        SECTION 3.2. COST OVERRUNS The Guarantors agree that, if for any reason
and at any time (and from time to time), the aggregate costs and expenses
(whether or not Project Costs as reflected in the Development Plan) which are,
in the opinion of the Agent, necessary (or which are at the beginning of each
calendar month, expected to be necessary) to be incurred on or prior to the
Release Date to develop, construct and complete the Mine in accordance with the
Agreed Project Standards exceed the Project Costs as reflected in the
Development Plan, the Guarantors will contribute cash to the Borrower in an
amount equal to such excess, in a sufficiently timely manner to permit the
Borrower to fund such excess costs and expenses as the same become due and
payable and otherwise in a form and manner acceptable to the Agent in the manner
set out herein. The Guarantors will deposit any contribution made by any of them
hereunder into the Operating Account.

        SECTION 3.3. ECONOMIC COMPLETION Without limiting any other provision of
this Agreement, the Guarantors hereby irrevocably and unconditionally undertakes
and agrees (as primary obligor) that Economic Completion will take place by no
later than the earlier of six months after the Mechanical Completion Date or 31
December, 2001. The Guarantors recognise that it is a condition to the
occurrence of Economic Completion that no Default shall then have occurred and
be continuing and that, in particular, that it is required that the financial
covenants contained in Section 8 2 4 of the Loan Agreement shall be shown to be
complied with (at all relevant times) as at the Economic Completion Date. As
part of its general undertakings contained in this Section and elsewhere in this
Agreement, the Guarantors will ensure, on or prior to the date referred to above
(and whether by way of a cash Capital Contribution, the advance of Approved
Subordinated Indebtedness or otherwise in a manner which is consistent with the
Loan Documents) that such covenants are capable of being complied with as
aforesaid. In addition, the Guarantors also undertakes that, as at the Release
Date, the amount standing to the credit of the Debt Service Reserve Account
shall not be less than the Required Debt Service Reserve Balance.

        SECTION 3.4. CONTROL  The Guarantors will exercise control over the
Borrower (whether through the voting of shares issued by the Borrower and held
by the Guarantors or its affiliates, by the appointment of directors to the
board of directors of the Borrower or otherwise), and will make available to the
Borrower such support (whether by way of the provision of personnel, expertise,
know-how, intellectual property, professional or managerial services, equipment,
plant, technology, finance or otherwise), in each case so as to enable the
Borrower to construct and develop the Mine (and to achieve Mechanical
Completion, Economic Completion and the Release Date) in accordance with the
Agreed Project Standards.

        SECTION 3.5. COMPLETION DEPOSIT ACCOUNT  At all times until and
including the Release Date, RRL shall maintain a balance standing to the credit
of the Completion Deposit Account with the Project Account Bank (Offshore) of
not less than U.S. $5,000,000, provided however, that if

             (a)     a Qualifying Project Cost Over-Run exists;

             (b)     RRJ and the Borrower have provided written notice to the
        Agent specifying the amount of such Qualifying Project Cost Over-Run and
        the amount intended to be withdrawn from the Completion Deposit Account
        in respect of payment of such Qualifying Project Cost Over-Run (the
        "Withdrawal Amount");

             (c)     RRL and the Borrower shall have provided evidence
        satisfactory to the Agent (acting in consultation with the Independent
        Engineer) confirming that the payment of such Withdrawal Amount, will
        (after taking into account any monies standing to the credit of the
        Completion Deposit Account following the withdrawal of such Withdrawal
        Amount and any then available Tranche B Loans) result in the achievement
        of Mechanical Completion (if not then achieved), Economic Completion (if
        not then achieved), and the satisfactory development of the Morila
        Project (in each case in accordance with the Development Plan), and the
        Agent shall have confirmed its satisfaction with such evidence and its
        approval of such Withdrawal Amount; and

             (d)     no Default shall then have occurred and be continuing,

        then RRL may instruct the Project Account Bank (Offshore) to transfer
        the Withdrawal Amount to the Operating Account and the proceeds thereof
        may be used to fund such Qualifying Project Cost Over-Run. Without
        prejudice to the right of any Lender Party to obtain any repayment or
        prepayment of any Obligation from the Completion Deposit Account, no
        amounts other than amounts referred to in the foregoing sentence may be
        disbursed from the Completion Deposit Account.

        SECTION 3.6. RECL CHANGE IN CONTROL  RECL agrees with the Agent, for the
benefit of each Lender Party that (notwithstanding the provisions of Section
2.5), at all times until all Commitments have been terminated and all
Obligations have been paid and performed in full, it will continue to directly
own (and to have sole power to vote and dispose of), free and clear of all liens
not less than sixty one percent (61%) of the share capital (however designated)
