      reasonably require. Each of Journey and Zico agree to work in good faith
      to assist the other to complete the Due Diligence process according to the
      following schedule:

      Vancouver with Journey’s Qualified Person(s).

	 	 
		
      March 14 to 17, 2008 – examination of drill cores,

      laboratories or other qualified laboratory as determined by Zico.

      assays during the examination of drill cores.

	 	 
		
      May 1 to 17, 2008 – Receipt and review of assays results.

their respective costs associated with this Due Diligence process. 

                    4.     
If, upon completion of the Due Diligence process, Zico determines at its sole
and unfettered discretion that the Work Product does not, in whole or in part,
meet the standards set forth in National Instrument 43-101 (“NI 43-101”) or the
standards and guidelines set forth by the Canadian Institute of Mining, Zico
shall so notify each of the other parties hereto and, upon delivery of such
notice, this Agreement shall be null and void and without further effect
whatsoever. As part of its due diligence, Zico shall have the right to split the
Cambior drill core and the Trio-Journey drill core and to have the same assayed.
Notwithstanding any other terms or conditions of this Agreement (including any
termination of this Agreement for any reason whatsoever), Mackay and Honolulu
shall retain all right, title, possession and interest in and to any and all
Cambior drill core and data.

                    5.      Each

that the Work Product generated after March 17, 2004 meets the standards set
forth in NI 43-101 and the standards and guidelines set forth by the Canadian
Institute of Mining and is suitable for calculation of a mineral resource in
accordance with NI 43-101 and for mine planning. These representations and
warranties shall survive any termination of this Agreement. These
representations and warranties shall not survive the termination of this
Agreement if Zico determines that the Work 

Product does not meet NI 43-101 and the standards and
guidelines set forth by the Canadian Institute of Mining. 

                    6.      Each
of Journey and Trio represents and warrants to each of Mackay, Honolulu and Zico
that the Cambior Drill Core has been handled and maintained in accordance with
the standards set forth in NI 43-101 for handling and maintaining drill core
while in the possession of Journey. These representations and warranties shall
survive any termination of this Agreement. 

                    7.      Zico
shall have the right to contact and receive information and data related to the
Empire Mine from any employee, agent or consultant of Journey or Trio, including

accordance with their respective Term Loan Commitments. The failure of any

requested Borrowing.

     SECTION 2.4. Funding of
Borrowings.

     (a) Each Lender shall make each
Term Loan to be made by it hereunder on the proposed date thereof by wire

Loans available to the Borrower by promptly crediting the amounts so received to
the Proceeds Account.

     (b) Unless the Administrative
Agent shall have received notice from a Lender prior to the proposed date of any
Borrowing that such Lender will not make available to the Administrative Agent
such Lender’s share of such Borrowing, the Administrative Agent may assume that
such Lender has made such share available on such date in accordance with
paragraph (a) of this Section and may, in reliance upon such assumption, make
available to the Borrower a corresponding amount. In such event, if a Lender has
not in fact made its share of the applicable Borrowing available to the
Administrative Agent, then the applicable Lender and the Borrower severally
agree to pay to the Administrative Agent forthwith on demand such corresponding
amount with interest thereon, for each day from and including the date such
amount is made available to the Borrower to but excluding the date of payment to
the Administrative Agent, at (i) in the case of such Lender, the rate determined

the Borrower to each Lender hereunder and (iii) the amount of
any sum received by the Administrative Agent hereunder for the account of the

     (c) The entries made in the
accounts maintained pursuant to paragraph (a) or (b) of this Section shall be
prima facie evidence of the existence and amounts of the obligations
recorded therein; provided that the failure of any Lender or the

any manner affect the obligation of the Borrower to repay the Term Loans in
accordance with the terms of this Agreement.

Term Loans made by it be evidenced by a promissory note. In such event, the
Borrower shall prepare, execute and deliver to such Lender a promissory note

Administrative Agent in writing of any prepayment hereunder not later than 11:00
a.m., New York City time, at least five Business Days before the date of
prepayment; each such notice shall be irrevocable and shall specify the
prepayment date and the principal amount of each Term Loan or portion thereof to
be prepaid; promptly following receipt of any such notice, the Administrative
Agent shall advise the Lenders of the contents thereof;

     (b) each prepayment shall be

recently ended); and

     (e) so long as such prepayment is
made with the proceeds of internally generated funds (and not a refinancing)
then no prepayment penalty shall apply; provided that a prepayment

     SECTION 2.9. Mandatory
Prepayments.

     (a) Excess Cash Flow.
After the termination of the Availability Period, on each date of delivery of
financial statements as required by Sections 5. 1(a) and (b), the Borrower shall
deliver to the Administrative Agent an Excess Cash Flow Certificate for the
fiscal quarter most recently ended and shall simultaneously prepay outstanding
Term Loans in the aggregate principal amount equal to the amount of Excess Cash
Flow as indicated on such certificate, provided that, once the amounts prepaid
by the Borrower in terms of this Section are equal to or in excess of $1,500,000
in the aggregate, the Borrower shall be thereafter obliged to prepay outstanding
Term Loans in the aggregate principal amount equal to 25% of Excess Cash Flow as
indicated on such certificate. The Administrative Agent shall notify the
Borrower, within 10 Business Days after receipt of such certificate, whether it
validates and approves such certificate, and, if it does not validate and
approve the certificate, advise the Borrower of the amount of the Excess Cash
Flow as calculated by the Administrative Agent. In the absence of manifest error
on the part of the Administrative Agent, the Borrower shall adjust the amount to
be paid by it on the following Principal Payment Date by the amount necessary to
take account of the discrepancy in such the certificate, as certified by the
Administrative Agent. Any such prepayment shall be applied in accordance with
clause (e) hereof.

     (b) Dispositions. The
Borrower shall prepay the Term Loans in an amount equal to 100% of the Net Cash
Proceeds of any Disposition or series of Dispositions by any Loan Party or any
Subsidiary of a Loan Party pursuant to Section 6.3(a)(iii) generating Net Cash
Proceeds in excess of $250,000 in the aggregate after the Closing Date. Each
such prepayment shall be due promptly upon receipt by the such Person of such
Net Cash Proceeds and shall be applied as set forth in clause (e) below.
Notwithstanding the foregoing, the Borrower shall not be required to apply any
such proceeds in accordance with clause (e) to the extent that the Borrower
advises the Administrative Agent at the time of the relevant Disposition that
the Borrower intends to use the Net Cash Proceeds thereof to finance one or more
Operating Costs or Project Development Costs permitted by this Agreement, and
such Net Cash Proceeds are in 

- 19 -

fact so applied (or contractually committed to be applied) to
such expenditures within 180 days of such Disposition (it being understood that
Net Cash Proceeds shall be deemed to be utilized in the same order in which they
are received. Any such Net Cash Proceeds which are not applied (or contractually
committed to be applied) within such 180 day period as required by the
immediately preceding sentence shall forthwith be applied in accordance with
clause (e). Notwithstanding the foregoing, the Borrower shall not be required to
prepay any proceeds realized form the sale of any Dispositions generated from
the sale of assets exclusively related to the Coyote Springs or Mimbres sites.
In addition, the Borrower agrees that the sale of any drilling equipment no
longer used in the business of the Borrower shall be considered to be
Disposition under Section 6.3(a)(iii) . 

     (c) Casualty Events. The
Borrower shall prepay the Term Loans in an amount equal to 100% of the Net Cash
Proceeds received by any Loan Party or any Subsidiary of a Loan Party in
connection with any Casualty Event or series of Casualty Events generating Net
Cash Proceeds in excess of $1,000,000 in the aggregate for any fiscal year. Each
such prepayment shall be due promptly upon receipt by such Person of such Net
Cash Proceeds and shall be applied as set forth in clause (e) below.
Notwithstanding the foregoing, the Borrower shall not be required to apply any
such proceeds in accordance with clause (e) to the extent that the Company
advises the Administrative Agent at the time of the relevant Casualty Event that
it intends to use Net Cash Proceeds thereof to finance the replacement or repair
of such affected property, and such Net Cash Proceeds are in fact so applied (or
contractually committed to be applied) to such affected Property within 360 days
of receipt thereof (it being understood that Net Cash Proceeds shall be deemed
to be utilized in the same order in which they are received). Any such Net Cash
Proceeds which are not applied (or contractually committed to be applied) within
such 360 day period as required by the immediately preceding sentence shall
forthwith be applied as set forth in clause (e) below.

     (d) Debt Issuances. The
Borrower shall prepay the Term Loans in an amount equal to 100% of the Net Cash
Proceeds received by the Borrower or any Subsidiary in connection with any Debt
Issuance. Each such prepayment shall be due promptly upon receipt by such Person
of such Net Cash Proceeds and shall be applied as set forth in clause (e)
below.

     (e) Application. Any such
prepayment shall, be applied (i) first, to the Debt Service Reserve Account
until fully funded and (ii) thereafter, pro rata to installments of the Term
Loan in inverse order of maturity until paid in full.

     SECTION 2.10. Fees.

     (a) The Borrower agrees to pay to
the Administrative Agent for the account of each Lender a facility fee, which
shall accrue at 0.250% per annum on the daily amount of the unused Term Loan
Commitment of such Lender during the Availability Period, subject to the last
sentence hereof. Accrued facility fees shall be payable in arrears on the last
day of March, June, September and December of each year and on the date on which
the Term Loan Commitments terminate, commencing on the first such date to occur
after the date hereof. All facility fees shall be computed on the basis of a
year of 360 days and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day). Such fees shall be payable
on an amount of unused commitments for each day equal to the amount of 

- 20 -

unused Commitments set forth in the table below minus
the amount of Term Loans outstanding on such day: 

  	
        Period 

	
        Amount of 
unused 
Commitments 

	From the Closing Date through the last day of September,
      2007 	$ 3,000,000 
	October 2007 	7,500,000 
	November 2007 	12,500,000 
	December 2007 	16,000,000 
	January 2008 	20,500,000 
	February 2008 	22,000,000 
	March 2008 	23,000,000 
	April 2008 through the end of the Availability Period 	25,000,000

For purposes of illustration, (a) if Term Loans in an amount in
excess of $9,000,000 were outstanding on September 15, 2007, no such fee would
be payable on such day, and (b) if Term Loans in an amount of $2,000,000 were
outstanding on September 15, 2007, such fee would be payable in respect of
$1,000,000 in unused Term Loan Commitments on such day.

     (b) All fees payable hereunder
shall be paid on the dates due, in immediately available funds, to the
Administrative Agent for distribution, in the case of facility fees and
participation fees, to the Lenders. Fees paid shall not be refundable under any
circumstances.

     SECTION 2.11.
Interest.

     (a) The aggregate principal
amount of all outstanding Term Loans shall bear interest from the date such Term
Loan is made until the date the principal of such Term Loan is repaid at an
annual rate equal the LIBOR Rate for the Interest Period in effect for such Term
Loan plus the Applicable Margin.

     (b) Notwithstanding the
foregoing, upon any Event of Default, all principal amounts hereunder shall bear
interest, after as well as before judgment, at a rate per annum equal to 3% plus
the rate otherwise applicable to such Term Loan as provided in the preceding
paragraph of this Section.

- 21 -

     (c) Accrued interest on each Term
Loan shall be payable in arrears on each Interest Payment Date; provided
that (i) interest accrued pursuant to paragraph (b) of this Section shall be
payable on demand, and (ii) in the event of any prepayment of any Term Loan,
accrued interest on the principal amount prepaid shall be payable on the date of
such prepayment. Notwithstanding the foregoing, for each Interest Payment Date
prior to the first Principal Payment Date, any interest payable with respect to
the Term Loans on such Interest Payment Date shall be capitalized and shall
increase the unpaid principal amount of the Term Loans, provided that any
interest capitalized pursuant to the preceding sentence shall not reduce amounts
available for drawing under Section 2.1.

     (d) The applicable LIBOR Rate
shall be determined by the Administrative Agent, and such determination shall be
conclusive absent manifest error.

     SECTION 2.12. Alternate Rate
of Interest. If prior to the commencement of any Interest Period for any
Term Loan:

     (a) the Administrative Agent
determines (which determination shall be conclusive absent manifest error) that
adequate and reasonable means do not exist for ascertaining the LIBOR Rate for
such Interest Period; or

     (b) the Administrative Agent is
advised by the Required Lenders that the LIBOR Rate for such Interest Period
will not adequately and fairly reflect the cost to such Lenders (or Lender) of
making or maintaining their Term Loans (or its Term Loan) included in such
Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the
Borrower and the Lenders by telephone or telecopy as promptly as practicable
thereafter and, until the Administrative Agent notifies the Borrower and the
Lenders that the circumstances giving rise to such notice no longer exist, (i)
no borrowing request shall be effective, and (ii) the Borrower and the Lenders
shall enter into negotiations in good faith with a view to establish a
satisfactory alternative basis for computing interest on the Term Loans.

     SECTION 2.13. Increased
Costs.

     (a) If any Change in Law
shall:

     (i) impose, modify or deem
applicable any reserve, special deposit or similar requirement against assets
of, deposits with or for the account of, or credit extended by, any Lender;
or

     (ii) impose on any Lender or the
London interbank market any other condition affecting this Agreement or Term
Loans made by such Lender;

and the result of any of the foregoing shall be to increase the
cost to such Lender of making or maintaining any Term Loan (or of maintaining
its obligation to make Term Loans) or to reduce the amount of any sum received
or receivable by such Lender hereunder (whether of principal, interest or
otherwise), then the Borrower will pay to such Lender, such additional amount or
amounts as will compensate such Lender for such additional costs incurred or
reduction suffered.

- 22 -

     (b) If any Lender determines that
any Change in Law regarding capital requirements has or would have the effect of
reducing the rate of return on such Lender’s capital or on the capital of such
Lender’s holding company, if any, as a consequence of this Agreement or the Term
Loans made by, such Lender to a level below that which such Lender or such
Lender’s holding company could have achieved but for such Change in Law (taking
into consideration such Lender’s policies and the policies of such Lender’s or
holding company with respect to capital adequacy), then from time to time the
Borrower will pay to such Lender, as the case may be, such additional amount or
amounts as will compensate such Lender or such Lender’s holding company for any
such reduction suffered.

     (c) A certificate of a Lender
setting forth the amount or amounts necessary to compensate such Lender or its
holding company, as the case may be, as specified in paragraph (a) or (b) of
this Section shall be delivered to the Borrower and shall be conclusive absent
manifest error. The Borrower shall pay such Lender, as the case may be, the
amount shown as due on any such certificate within 10 days after receipt
thereof.

     (d) Failure or delay on the part
of any Lender to demand compensation pursuant to this Section shall not
constitute a waiver of such Lender’s right to demand such compensation;
provided that the Borrower shall not be required to compensate a Lender
pursuant to this Section for any increased costs or reductions incurred more
than 270 days prior to the date that such Lender notifies the Borrower of the
Change in Law giving rise to such increased costs or reductions and of such
Lender’s intention to claim compensation therefor; provided further that,
if the Change in Law giving rise to such increased costs or reductions is
retroactive, then the 270-day period referred to above shall be extended to
include the period of retroactive effect thereof.

     SECTION 2.14. Break Funding
Payments. In the event of (a) the payment of any principal of any Term Loan
other than on the last day of an Interest Period applicable thereto (including
as a result of an Event of Default), (b) the failure to borrow any Term Loan on
the date specified in any notice delivered pursuant hereto, then, in each such
event, the Borrower shall compensate each Lender for the loss, cost and expense
attributable to such event. Such loss, cost or expense to any Lender shall be
deemed to include an amount determined by such Lender to be the excess, if any,
of (i) the amount of interest which would have accrued on the principal amount
of such Term Loan had such event not occurred, at the LIBOR Rate that would have
been applicable to such Term Loan, for the period from the date of such event to
the last day of the then current Interest Period therefor (or, in the case of a
failure to borrow, for the period that would have been the Interest Period for
such Term Loan), over (ii) the amount of interest which would accrue on such
principal amount for such period at the interest rate which such Lender would
bid were it to bid, at the commencement of such period, for dollar deposits of a
comparable amount and period from other banks in the eurodollar market. A
certificate of any Lender setting forth any amount or amounts that such Lender
is entitled to receive pursuant to this Section shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate on demand.

- 23 -

     SECTION 2.15. Taxes.

     (a) Any and all payments by or on
account of any obligation of the Borrower hereunder shall be made free and clear
of any present and future tax liability and without deduction for any
Indemnified Taxes or Other Taxes; provided that if the Borrower shall be
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section) the Administrative Agent or Lender (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

     (b) In addition, the Borrower
shall pay any Other Taxes to the relevant Governmental Authority in accordance
with applicable law.

     (c) The Borrower shall indemnify
the Administrative Agent and each Lender, within 10 days after written demand
therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by
the Administrative Agent or such Lender, as the case may be, on or with respect
to any payment by or on account of any obligation of the Borrower hereunder
(including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest
and reasonable expenses arising therefrom or with respect thereto, whether or
not such Indemnified Taxes or Other Taxes were correctly or legally imposed or
asserted by the relevant Governmental Authority. A certificate as to the amount
of such payment or liability delivered to the Borrower by a Lender or by the
Administrative Agent on its own behalf or on behalf of a Lender, shall be
conclusive absent manifest error.

     (d) As soon as practicable after
any payment of Indemnified Taxes or Other Taxes by the Borrower to a
Governmental Authority, the Borrower shall deliver to the Administrative Agent
the original or a certified copy of a receipt issued by such Governmental
Authority evidencing such payment, a copy of the return reporting such payment
or other evidence of such payment reasonably satisfactory to the Administrative
Agent.

     (e) Any Foreign Lender that is
entitled to an exemption from or reduction of withholding tax under the law of
the jurisdiction in which the Borrower is located, or any treaty to which such
jurisdiction is a party, with respect to payments under this Agreement shall
deliver to the Borrower (with a copy to the Administrative Agent), at the time
or times prescribed by applicable law, such properly completed and executed
documentation prescribed by applicable law or reasonably requested by the
Borrower as will permit such payments to be made without withholding or at a
reduced rate.

     (f) If the Administrative Agent
or a Lender determines, in its sole discretion, that it has received a refund of
any Taxes or Other Taxes as to which it has been indemnified by the Borrower or
with respect to which the Borrower has paid additional amounts pursuant to this
Section 2.15, it shall pay over such refund to the Borrower (but only to the
extent of indemnity payments made, or additional amounts paid, by the Borrower
under this Section 2.15 with respect to the Taxes or Other Taxes giving rise to
such refund), net of all out-of-pocket expenses 

- 24 -

of the Administrative Agent or such Lender and without interest
(other than any interest paid by the relevant Governmental Authority with
respect to such refund); provided, that the Borrower, upon the request of the
Administrative Agent or such Lender, agrees to repay the amount paid over to the
Borrower (plus any penalties, interest or other charges imposed by the relevant
Governmental Authority) to the Administrative Agent or such Lender in the event
the Administrative Agent or such Lender is required to repay such refund to such
Governmental Authority. This Section shall not be construed to require the
Administrative Agent or any Lender to make available its tax returns (or any
other information relating to its taxes which it deems confidential) to the
Borrower or any other Person.

     SECTION 2.16. Payments
Generally; Pro Rata Treatment; Sharing of Set-offs.

     (a) The Borrower shall make each
payment required to be made by it hereunder (whether of principal, interest or
fees, or of amounts payable under Section 2.13, 2.14 or 2.15, or otherwise)
prior to 12:00 noon, New York City time, on the date when due, in immediately
available funds, without set-off or counterclaim. Any amounts received after
such time on any date may, in the discretion of the Administrative Agent, be
deemed to have been received on the next succeeding Business Day for purposes of
calculating interest thereon. All such payments shall be made into account
number 2000193000423 maintained by the Administrative Agent with Wachovia Bank,
N.A. located in New York, New York, except that payments pursuant to Sections
2.13, 2.14, 2.15 and 10.3 shall be made directly to the Persons entitled
thereto. The Administrative Agent shall distribute any such payments received by
it for the account of any other Person to the appropriate recipient promptly
following receipt thereof. If any payment hereunder shall be due on a day that
is not a Business Day, the date for payment shall be extended to the next
succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments
hereunder shall be made in dollars.

     (b) If at any time insufficient
funds are received by and available to the Administrative Agent to pay fully all
amounts of principal, interest and fees then due hereunder, such funds shall be
applied (i) first, towards payment of interest and fees then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
interest and fees then due to such parties, and (ii) second, towards payment of
principal then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of principal then due to such parties.

     (c) If any Lender shall, by
exercising any right of set-off or counterclaim or otherwise, obtain payment in
respect of any principal of or interest on any of its Term Loans resulting in
such Lender receiving payment of a greater proportion of the aggregate amount of
its Term Loans and accrued interest thereon than the proportion received by any
other Lender, then the Lender receiving such greater proportion shall purchase
(for cash at face value) participations in the Term Loans of other Lenders to
the extent necessary so that the benefit of all such payments shall be shared by
the Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Term Loans; provided that (i) if any
such participations are purchased and all or any portion of the payment giving
rise thereto is recovered, such participations shall be rescinded and the
purchase price restored to the extent of such recovery, without interest, and
(ii) the provisions of this paragraph shall not be construed to 

- 25 -

apply to any payment made by the Borrower pursuant to and in
accordance with the express terms of this Agreement or any payment obtained by a
Lender as consideration for the assignment of or sale of a participation in any
of its Term Loans to any assignee or participant, other than to the Loan Parties
or any Affiliate thereof (as to which the provisions of this paragraph shall
apply). The Borrower consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against the
Borrower rights of set-off and counterclaim with respect to such participation
as fully as if such Lender were a direct creditor of the Borrower in the amount
of such participation.

     (d) Unless the Administrative
Agent shall have received notice from the Borrower prior to the date on which
any payment is due to the Administrative Agent for the account of the Lenders
hereunder that the Borrower will not make such payment, the Administrative Agent
may assume that the Borrower has made such payment on such date in accordance
herewith and may, in reliance upon such assumption, distribute to the Lenders,
as the case may be, the amount due. In such event, if the Borrower has not in
fact made such payment, then each of the Lenders severally agrees to repay to
the Administrative Agent forthwith on demand the amount so distributed to such
Lender with interest thereon, for each day from and including the date such
amount is distributed to it to but excluding the date of payment to the
Administrative Agent, at the greater of the Federal Funds Effective Rate and a
rate determined by the Administrative Agent in accordance with banking industry
rules on interbank compensation.

     (e) If any Lender shall fail to
make any payment required to be made by it pursuant to Section 2.4(a), 2.16(d)
or 10.3(c) , then the Administrative Agent may, in its discretion
(notwithstanding any contrary provision hereof), apply any amounts thereafter
received by the Administrative Agent for the account of such Lender to satisfy
such Lender’s obligations under such Sections until all such unsatisfied
obligations are fully paid.

     SECTION 2.17. Mitigation
Obligations. If any Lender requests compensation under Section 2.13, or if
the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.15,
then such Lender shall use reasonable efforts to designate a different lending
office for funding or booking its Term Loans hereunder or to assign its rights
and obligations hereunder to another of its offices, branches or affiliates, if,
in the judgment of such Lender, such designation or assignment (i) would
eliminate or reduce amounts payable pursuant to Section 2.13 or 2.15, as the
case may be, in the future and (ii) would not subject such Lender to any
unreimbursed cost or expense and would not otherwise be disadvantageous to such
Lender. The Borrower hereby agrees to pay all reasonable costs and expenses
incurred by any Lender in connection with any such designation or
assignment.

ARTICLE III. 
REPRESENTATIONS AND
WARRANTIES

     Each Loan Party represents and
warrants to the Lenders that:

     SECTION 3.1. Status and
Power. The Borrower is a corporation duly incorporated and validly existing
under the laws of the State of Delaware. The Guarantor is a corporation duly

- 26 -

incorporated and validly existing under the laws of the State
of Nevada. Each Loan Party is duly qualified, registered or licensed in all
jurisdictions where such qualification, registration or licensing is required
except where the lack of such qualification, registration or licensing could not
reasonably be expected to have a Material Adverse Effect. Each Loan Party has
all requisite corporate capacity, power and authority to own, hold under license
or lease its properties, to carry on its business as now conducted and to
otherwise enter into, and carry out the Transactions. None of the Loan
Parties nor any of their property has any immunity from jurisdiction of any

prior to judgment, attachment in aid of execution, execution or otherwise).

     SECTION 3.2. Authorization;
Enforceability. All necessary action, corporate or otherwise, has
been taken to authorize the execution, delivery and performance by each Loan
Party of the Loan Documents to which it is a party. Each Loan Party has duly
executed and delivered the Loan Documents to which it is a party. The Loan
Documents to which each Loan Party is a party are legal, valid and binding
obligations of such Loan Party, enforceable against such Loan Party by the other
parties thereto in accordance with their respective terms, except to the extent
that the enforceability thereof may be limited by applicable bankruptcy,
insolvency, moratorium, reorganization, fraudulent conveyance and other similar
laws of general application limiting the enforcement of creditors’ rights
generally and the fact that the courts may deny the granting or enforcement of
equitable remedies.

     SECTION 3.3. No
Conflicts. The execution, delivery and performance by each Loan Party
of the Loan Documents and Material Contracts to which it is a party, and the
consummation of the transactions contemplated herein and therein (i) do not
conflict with, result in any breach or violation of, or constitute a default
under the terms, conditions or provisions of (A) the articles of incorporation
or by-laws (or comparable constituting documents) of, or any shareholder
agreement relating to, any Loan Party or (B) any law, regulation, judgment,
decree or order binding on or applicable to any Loan Party or to which its
property is subject or any agreement, lease, license, permit or other instrument
to which any Loan Party is a party or is otherwise bound or by which any Loan
Party benefits or to which any of its property is subject except, in each case,
to the extent that such conflict does not and could not reasonably be expected
to have a Material Adverse Effect and (ii) do not require the consent or
approval of any Governmental Authority or any other Person which has not been
obtained and provided to the Administrative Agent.

     SECTION 3.4. Financial
Statements. The Borrower’s unaudited consolidated financial statements
(consisting of a balance sheet, statement of operations, statement of changes in
shareholder’s deficit, and statement of cash flows) for the quarter ended March
31, 2007, were prepared in accordance with GAAP consistently applied (except
that certain information and footnote disclosures normally included in financial
statements prepared in accordance with GAAP have been omitted or condensed and
subject to normal and recurring year-end adjustments which will not be
individually or in the aggregate material) in accordance with past practice and
no Material Adverse Change has occurred since such date. Such financial
statements fairly present the financial condition of the Borrower as at the date
thereof and the financial statements fairly present the results of operations,
cash flow and income of the Borrower during the fiscal period covered
thereby.

- 27 -

     SECTION 3.5. Intentionally
Omitted.

     SECTION 3.6. Litigation,
etc. Except as described in Section 3.6 of the Disclosure Schedule,
there are no actions, suits, investigations, claims or proceedings which have
been commenced or, to the knowledge of any Loan Party, have been threatened in
writing against or affecting any Loan Party before any Governmental Authority
which contest any of the transactions contemplated in any of the Loan Documents
or Material Contracts. There are no actions, suits, investigations, claims or
proceedings which have been commenced or, to the knowledge of any Loan Party,
have been threatened in writing against or affecting any Loan Party before any
Governmental Authority which could reasonably be expected to have a Material
Adverse Effect.

     SECTION 3.7. Title to
Assets. Except as described in Section 3.7 of the Disclosure Schedule, each
Loan Party has a good and marketable title to all of its property and assets
which constitute Collateral, free from any Liens other than the Permitted Liens,
and no Person has any agreement or right to acquire any of the Collateral except
as permitted hereunder.

     SECTION 3.8. Conduct of
Business. No Loan Party is in violation of any mortgage, franchise,
license, certificate of approval, permit, judgment, decree, order, statute, rule
or regulation relating in any way to itself or to the operation of its business
or to its property or assets in a manner which could reasonably be expected to
have a Material Adverse Effect. Except as set forth in Section 3.8 of the
Disclosure Schedule, each Loan Party has all licenses, certificates of approval,
permits, registrations, approvals and consents which are required to own its
properties and assets and to operate its businesses where they are currently
being operated, other than any such items the absence of which could not
reasonably be expected to have a Material Adverse Effect.

     SECTION 3.9. Labor and
Employment Matters. Except as described in Section 3.9 of the Disclosure
Schedule, there are no material employment agreements covering management of the
Borrower and there are no collective bargaining agreements or other labor
agreements covering any employees of the Borrower. Hours worked by and payment
made to employees of the Borrower have not been in violation of any Applicable

deviation has been explained and incorporated into a prior Financial Model; and
(iii) include such other information as the Administrative Agent may reasonably
request.

     (b) The Administrative Agent
shall have 10 days from the date of receipt of an updated Financial Model to
accept or reject such updated Financial Model. In the event that the
Administrative Agent accepts such updated Financial Model, it shall become the
current Financial Model. The Administrative Agent shall promptly review such
updated Financial Model, and if the Administrative Agent does not accept such
updated Financial Model, it shall promptly notify the Borrower thereof, the
Borrower shall, within 10 Business Days and after consultation with the
Administrative Agent as to the reasons therefor, submit an appropriately revised
Financial Model. Following such resubmission, the process shall be repeated
until the Financial Model has been accepted by the Administrative Agent. To the
extent that a fiscal quarter commences without a Financial Model having been
approved in accordance with this Section 5.10, the previously approved Financial
Model shall remain in effect until a revised Financial Model shall have been
approved.

ARTICLE VIII.
THE ADMINISTRATIVE
AGENT

     Each of the Lenders hereby
irrevocably appoints the Administrative Agent as its agent and authorizes the
Administrative Agent to take such actions on its behalf and to exercise such
powers as are delegated to the Administrative Agent by the terms hereof,
together with such actions and powers as are reasonably incidental thereto.

     The bank serving as the
Administrative Agent hereunder shall have the same rights and powers in its
capacity as a Lender as any other Lender and may exercise the same as though it
were not the Administrative Agent, and such bank and its Affiliates may accept
deposits from, lend money to and generally engage in any kind of business with
the Loan Parties or other Affiliate thereof as if it were not the Administrative
Agent hereunder.

     The Administrative Agent shall
not have any duties or obligations except those expressly set forth herein.
Without limiting the generality of the foregoing, (a) the Administrative Agent
shall not be subject to any fiduciary or other implied duties, regardless of
whether a Default has occurred and is continuing, (b) the Administrative Agent
shall not have any duty to take any discretionary action or exercise any
discretionary powers, except discretionary rights and powers expressly
contemplated hereby that the Administrative Agent is required to exercise in
writing as directed by the Required Lenders (or such other number or percentage
of the Lenders as shall be necessary under the circumstances as provided in
Section 10.2), and (c) except as expressly set forth herein, the Administrative
Agent shall not have any duty to disclose, and shall not be liable for the
failure to disclose, any information relating to any Loan Party that is
communicated to or obtained by the bank serving as Administrative Agent or any
of its Affiliates in any capacity. The Administrative Agent shall not be liable
for any action taken or not taken by it with the consent or at the request of
the Required Lenders (or such other number or percentage of the Lenders as shall
be necessary under the circumstances as provided in Section 10.2) or in the
absence of its own gross negligence or willful misconduct. The Administrative
Agent shall be deemed not to have knowledge of any Default unless and until
written notice thereof is given to the Administrative Agent by the Borrower or a
Lender, and the Administrative Agent shall not be responsible for or have any
duty to ascertain or inquire into (i) any statement, warranty or representation
made in or in connection with this Agreement, (ii) the contents of any
certificate, report or other document delivered hereunder or in connection
herewith, (iii) the performance or observance of any of the covenants,
agreements or other terms or conditions set forth herein, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement or any other
agreement, instrument or document, or (v) the satisfaction of any condition set
forth in Article IV or elsewhere herein, other than to confirm receipt of items
expressly required to be delivered to the Administrative Agent.

     The Administrative Agent shall be
entitled to rely upon, and shall not incur any liability for relying upon, any
notice, request, certificate, consent, statement, instrument, document or other
writing believed by it to be genuine and to have been signed or sent by the
proper Person. The Administrative Agent also may rely upon any statement made to
it orally or by telephone 

- 45 -

and believed by it to be made by the proper Person, and shall
not incur any liability for relying thereon. The Administrative Agent may
consult with legal counsel (who may be counsel for the Borrower), independent
accountants and other experts selected by it, and shall not be liable for any
action taken or not taken by it in accordance with the advice of any such
counsel, accountants or experts.

     The Administrative Agent may
perform any and all its duties and exercise its rights and powers by or through
any one or more sub-agents appointed by the Administrative Agent. The
Administrative Agent and any such sub-agent may perform any and all its duties
and exercise its rights and powers through their respective Related Parties. The
exculpatory provisions of the preceding paragraphs shall apply to any such
sub-agent and to the Related Parties of the Administrative Agent and any such
sub-agent, and shall apply to their respective activities in connection with the
syndication of the Term Loan provided for herein as well as activities as
Administrative Agent.

     Subject to the appointment and
acceptance of a successor Administrative Agent as provided in this paragraph,
the Administrative Agent may resign at any time by notifying the Lenders and the
Borrower. Upon any such resignation, the Required Lenders shall have the right,
in consultation with the Borrower, to appoint a successor. If no successor shall
have been so appointed by the Required Lenders and shall have accepted such
appointment within 30 days after the retiring Administrative Agent gives notice
of its resignation, then the retiring Administrative Agent may, on behalf of the
Lenders, appoint a successor Administrative Agent which shall be a bank with an
office in New York, New York, or an Affiliate of any such bank. Upon the
acceptance of its appointment as Administrative Agent hereunder by a successor,
such successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder. The fees payable by the Borrower to a successor Administrative Agent
shall be the same as those payable to its predecessor unless otherwise agreed
between the Borrower and such successor. After the Administrative Agent’s
resignation hereunder, the provisions of this Article and Section 10.3 shall
continue in effect for the benefit of such retiring Administrative Agent, its
sub-agents and their respective Related Parties in respect of any actions taken
or omitted to be taken by any of them while it was acting as Administrative
Agent.

     Each Lender acknowledges that it
has, independently and without reliance upon the Administrative Agent or any
other Lender and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Lender also acknowledges that it will, independently and without
reliance upon the Administrative Agent or any other Lender and based on such
documents and information as it shall from time to time deem appropriate,
continue to make its own decisions in taking or not taking action under or based
upon this Agreement, any related agreement or any document furnished hereunder
or thereunder.

ARTICLE IX. 
GUARANTY

     SECTION 9.1. Guaranty.
Guarantor hereby unconditionally and irrevocably guarantees to each of the
Lenders the punctual payment, performance in full and observance when due,
whether at stated maturity, by acceleration or otherwise, of the Borrower’s
Obligations (the “Guaranteed Obligations”) now or hereafter existing
under any Loan Document, whether for principal, interest (including, without
limitation, all interest that accrues after the commencement of any bankruptcy
proceeding of the Borrower, whether or not constituting an allowed claim in such
bankruptcy proceeding), fees, commissions, expense reimbursements,
indemnifications or otherwise, and agrees to pay any and all costs, fees and
expenses (including reasonable counsel fees and expenses) incurred by the
Administrative Agent and the Lenders in enforcing any rights under the guaranty
set forth in this Article IX, as they become due from time to time in accordance
with the express provisions of the Loan Documents. The Administrative Agent
shall be entitled to enforce this Guarantee for its own benefit and the ratable
benefit of the Lenders and each Lender shall be entitled to enforce this
Guarantee for its own benefit through the Administrative Agent in respect of the
Guaranteed Obligations owing to it but without duplication. Without limiting the
generality of the foregoing, Guarantor’s liability shall extend to all amounts
that constitute part of the Guaranteed Obligations and would be owed by the
Borrower to the Administrative Agent and the Lenders under any Loan Document but
for the fact that they are unenforceable or not allowable due to the existence
of an bankruptcy proceeding involving the Borrower.

     SECTION 9.2. Guaranty
Absolute. Guarantor guarantees that the Guaranteed Obligations will
be paid strictly in accordance with the terms of the Loan Documents, regardless
of any law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of the Administrative Agent or the
Lenders with respect thereto. The obligations of Guarantor under this Article IX
are independent of the Guaranteed Obligations, and a separate action or actions
may be brought and prosecuted against Guarantor to enforce such obligations,
irrespective of whether any action is brought against the Borrower or whether
the Borrower is joined in any such action or actions. The liability of Guarantor
under this Article IX constitutes a primary obligation, and not a contract of
surety, and shall be irrevocable, absolute and unconditional irrespective of,
and Guarantor hereby irrevocably waives any defenses it may now or hereafter
have in any way relating to, any or all of the following:

     (a) any lack of validity or
enforceability of any Loan Document or any agreement or instrument relating
thereto;

     (b) any change in the time,
manner or place of payment of, or in any other term of, all or any of the
Guaranteed Obligations, or any other amendment or waiver of or any consent to
departure from any Loan Document, including, without limitation, any increase in
the Guaranteed Obligations resulting from the extension of additional credit to
the Borrower or otherwise

     (c) any taking, exchange,
release, subordination or non-perfection of any of the Collateral, or any
taking, release or amendment or waiver of or consent to departure from any other
guaranty, for all or any of the Guaranteed Obligations;

- 47 -

     (d) any change, restructuring or
termination of the corporate structure or existence of any of the Loan Parties;
or

     (e) except for payment in full of
the Guaranteed Obligations, any other circumstance (including, without
limitation, any statute of limitations) or any existence of or reliance on any
representation by the Administrative Agent or the Lenders that might otherwise
constitute a defense available to, or a discharge of, any of the Loan Parties or
any other guarantor or surety.

This Article IX shall continue to be effective or be
reinstated, as the case may be, if at any time any payment of any of the
Guaranteed Obligations is rescinded or must otherwise be returned by the
Administrative Agent or the Lenders or any other Person upon the insolvency,
bankruptcy or reorganization of the Borrower or otherwise (and whether as a
result of any demand, settlement, litigation or otherwise), all as though such
payment had not been made.

     SECTION 9.3. Waiver.
Guarantor hereby waives promptness, diligence, notice of acceptance and any
other notice with respect to any of the Guaranteed Obligations and this Article
IX and any requirement that the Administrative Agent or the Lenders exhaust any
right or take any action against any of the Loan Parties or any other Person or
any Collateral. Guarantor acknowledges that it will receive direct and indirect
benefits from the financing arrangements contemplated herein and that the waiver
set forth in this Section 9.3 is knowingly made in contemplation of such
benefits. Guarantor hereby waives any right to revoke this Article IX, and
acknowledges that this Article IX is continuing in nature and applies to all
Guaranteed Obligations, whether existing now or in the future.

     SECTION 9.4. Continuing
Guaranty; Assignments. This Article IX is a continuing guaranty and
shall (a) remain in full force and effect until payment in full of the
Guaranteed Obligations, (b) be binding upon Guarantor, its successors and
assigns and (c) inure to the benefit of and be enforceable by the Administrative
Agent and the Lenders and their successors, pledgees, transferees and assigns.
Without limiting the generality of the foregoing clause (c), any Lender may
pledge, assign or otherwise transfer all or any portion of its rights and
obligations under this agreement (including, without limitation, all or any
portion of its Term Loan Commitment and its Term Loans) to any other Person, and
such other Person shall thereupon become vested with all the benefits in respect
thereof granted such Lender herein or otherwise.

     SECTION 9.5.
Subrogation. Guarantor shall not exercise any rights that it may
now or hereafter acquire against the Borrower or any other guarantor that arise
from the existence, payment, performance or enforcement of Guarantor’s
obligations under this Article IX, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution or indemnification and any
right to participate in any claim or remedy of the Administrative Agent or the
Lenders against any of the Loan Parties or any other guarantor or any
Collateral, whether or not such claim, remedy or right arises in equity or under
contract, statute or common law, including, without limitation, the right to
take or receive from any of the Loan Parties or any other guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security solely on account of such claim, remedy or right, unless and
until payment in full of the Guaranteed Obligations; provided, that Guarantor
shall not have any rights 

- 48 -

hereunder against the Borrower if all or any portion of the
Guaranteed Obligations shall have been satisfied with proceeds from the exercise
of remedies in respect of the Equity Interest of the Borrower pursuant to any
Security Document. In addition, unless and until payment in full of the
Guaranteed Obligations, any indebtedness of the Borrower now or hereafter held
by Guarantor is subordinated in right of payment to the Guaranteed Obligations,
and any such indebtedness collected or received by Guarantor after an Event of
Default has occurred and is continuing but prior to payment in full of the
Guaranteed Obligations, shall be held in trust for Administrative Agent on
behalf of the Administrative Agent and the Lenders and shall forthwith be paid
over to Administrative Agent for the benefit of itself and the Lenders to be
credited and applied against the Guaranteed Obligations. If any amount shall be
paid to Guarantor in violation of the immediately preceding two sentences, such
amount shall be held in trust for the benefit of the Administrative Agent and
the Lenders and shall forthwith be paid to Administrative Agent for the benefit
of the Administrative Agent and the Lenders to be credited and applied to the
Guaranteed Obligations and all other amounts payable under this Article IX,
whether matured or unmatured, in accordance with the terms of this Agreement, or
to be held as Security for any Guaranteed Obligations or other amounts payable
under this Article IX thereafter arising. Upon payment in full of the Guaranteed
Obligations, the Administrative Agent and the Lenders will, at the Guarantor’s
request and expense, execute and deliver to the Guarantor appropriate documents,
without recourse and without representation or warranty, necessary to evidence
the transfer by subrogation to Guarantor of an interest in the Guaranteed
Obligations resulting from such payment by Guarantor.

     SECTION 9.6. Maximum
Obligations. Notwithstanding any provision herein contained to the
contrary, Guarantor’s liability with respect to the Obligations shall be limited
to an amount not to exceed, as of any date of determination, the amount that
could be claimed by the Administrative Agent and the Lenders from Guarantor
without rendering such claim voidable or avoidable under Section 548 of the
Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer Act,
Uniform Fraudulent Conveyance Act or similar statute or common law.

1st Floor, Old Mutual Place, London EC4V, Attention: The Head: Mining and
Resources (Telecopy No. 44-707-002-3408), with a copy to Nedbank Limited, 135

Specialized Finance;

- 49 -

     (iii) if
to any other Lender, to it at its address (or telecopy number) as indicted to
the Administrative Agent.

     (b) Notices and other
communications to the Lenders hereunder may be delivered or furnished by
electronic communications pursuant to procedures approved by the Administrative
Agent; provided that the foregoing shall not apply to notices pursuant to
Article II unless otherwise agreed by the Administrative Agent and the
applicable Lender. The Administrative Agent or the Borrower may, in its
discretion, agree to accept notices and other communications to it hereunder by
electronic communications pursuant to procedures approved by it; provided that
approval of such procedures may be limited to particular notices or
communications.

     (c) Any party hereto may change
its address or telecopy number for notices and other communications hereunder by
notice to the other parties hereto. All notices and other communications given
to any party hereto in accordance with the provisions of this Agreement shall be
deemed to have been given on the date of receipt.

     SECTION 10.2. Waivers;
Amendments. 

     (a) No failure or delay by the
Administrative Agent or any Lender in exercising any right or power hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or
the exercise of any other right or power. The rights and remedies of the
Administrative Agent and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any provision of this Agreement or consent to any departure by the Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Term Loan
shall not be construed as a waiver of any Default, regardless of whether the
Administrative Agent or any Lender may have had notice or knowledge of such
Default at the time.

     (b) Neither this Agreement nor
any provision hereof may be waived, amended or modified except pursuant to an
agreement or agreements in writing entered into by the Borrower and the Required
Lenders or by the Borrower and the Administrative Agent with the consent of the
Required Lenders; provided that no such agreement shall (i) increase the
Term Loan Commitment of any Lender without the written consent of such Lender,
(ii) reduce the principal amount of the Term Loans or reduce the rate of
interest thereon, or reduce any fees payable hereunder, without the written
consent of each Lender affected thereby, (iii) postpone the scheduled date of
payment of the principal amount of the Term Loans, or any interest thereon, or
any fees payable hereunder, or reduce the amount of, waive or excuse any such
payment, or postpone the scheduled date of expiration of any Term Loan
Commitment, without the written consent of each Lender affected thereby, (iv)
change Section 2.16(b) or (c) in a manner that would alter the pro rata sharing
of payments required thereby, without the written consent of each Lender, or (v)
change any of the provisions of this Section or the definition of “Required
Lenders” or any other provision hereof specifying the number or percentage of

- 50 -

Lenders required to waive, amend or modify any rights hereunder
or make any determination or grant any consent hereunder, without the written
consent of each Lender; provided further that no such agreement shall
amend, modify or otherwise affect the rights or duties of the Administrative
Agent hereunder without the prior written consent of the Administrative
Agent.

     SECTION 10.3. Expenses;
Indemnity; Damage Waiver.

     (a) The Borrower shall pay (i)
all reasonable out-of-pocket expenses incurred by the Administrative Agent and
its Affiliates, including the reasonable fees, charges and disbursements of any
advisor or counsel for the Administrative Agent or any Lender (provided
that the Borrower shall not be required to pay for more than one counsel to
the Administrative Agent and the Lenders, other than special local counsel), in
connection with the syndication of the Term Loans provided for herein (which in
any event shall be conducted in accordance with Section 10.4(b)), the due
diligence, preparation, negotiation and administration of this Agreement or any
amendments, modifications or waivers of the provisions hereof (whether or not
the transactions contemplated hereby or thereby shall be consummated) and the
other Loan Documents and (ii) all out-of-pocket expenses incurred by the
Administrative Agent or any Lender, including the fees, charges and
disbursements of any advisor or counsel for the Administrative Agent or any
Lender, in connection with the enforcement or protection of its rights in
connection with this Agreement, including its rights under this Section, or in
connection with the Term Loans made, including all such out-of-pocket expenses
incurred during any workout, restructuring or negotiations in respect of the
Term Loans.

     (b) The Borrower shall indemnify
the Administrative Agent and each Lender, and each Related Party of any of the
foregoing Persons (each such Person being called an “Indemnitee”)
against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, including the fees, charges and
disbursements of any counsel for any Indemnitee, incurred by or asserted against
any Indemnitee arising out of, in connection with, or as a result of (i) the
execution or delivery of this Agreement or any agreement or instrument
contemplated hereby, the performance by the parties hereto of their respective
obligations hereunder or the consummation of the Transactions or any other
transactions contemplated hereby, (ii) any Term Loan or the use of the proceeds
therefrom, (iii) any actual or alleged presence or release of Hazardous
Materials on or from any property owned or operated by the Loan Parties, or any
Environmental Liability related in any way to the Loan Parties, or (iv) any
actual or prospective claim, litigation, investigation or proceeding relating to
any of the foregoing, whether based on contract, tort or any other theory and
regardless of whether any Indemnitee is a party thereto; provided that
such indemnity shall not, as to any Indemnitee, be available to the extent that
such losses, claims, damages, liabilities or related expenses are determined by
a court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or willful misconduct of such Indemnitee.

     (c) To the extent that the
Borrower fails to pay any amount required to be paid by it to the Administrative
Agent under paragraph (a) or (b) of this Section, each Lender severally agrees
to pay to the Administrative Agent, such Lender’s Applicable Percentage
(determined as of the time that the applicable unreimbursed expense or indemnity
payment is sought) of such unpaid amount; provided that the unreimbursed
expense or indemnified loss, 

- 51 -

claim, damage, liability or related expense, as the case may
be, was incurred by or asserted against the Administrative Agent in its capacity
as such.

     (d) To the extent permitted by
applicable law, the Borrower shall not assert, and hereby waives, any claim
against any Indemnitee, on any theory of liability, for special, indirect,
consequential or punitive damages (as opposed to direct or actual damages)
arising out of, in connection with, or as a result of, this Agreement or any
agreement or instrument contemplated hereby, the Transactions or any Term Loan
or the use of the proceeds thereof.

     (e) All amounts due under this
Section shall be payable promptly after written demand therefor.

     SECTION 10.4. Successors and
Assigns.

     (a) The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns permitted hereby, except that (i)
the Borrower may not assign or otherwise transfer any of its rights or
obligations hereunder without the prior written consent of each Lender (and any
attempted assignment or transfer by the Borrower without such consent shall be
null and void) and (ii) no Lender may assign or otherwise transfer its rights or
obligations hereunder except in accordance with this Section. Nothing in this
Agreement, expressed or implied, shall be construed to confer upon any Person
(other than the parties hereto, their respective successors and assigns
permitted hereby, Participants (to the extent provided in paragraph (c) of this
Section) and, to the extent expressly contemplated hereby, the Related Parties
of each of the Administrative Agent and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

     (b) (i) Subject to the conditions
set forth in paragraph (b)(ii) below, any Lender may assign to one or more
assignees all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Term Loan Commitment and the Term Loans at
the time owing to it) with the prior written consent (such consent not to be
unreasonably withheld) of:

     (A) the
Borrower, provided that no consent of the Borrower shall be required for
an assignment to a Lender, an Affiliate of a Lender, or, if an Event of Default
has occurred and is continuing, any other assignee; provided that any such
assignment to an Affiliate shall in all cases be subject to Section 2.17;

     (B) the
Administrative Agent, provided that no consent of the Administrative
Agent shall be required for an assignment of any Term Loan Commitment to an
assignee that is a Lender with a Term Loan Commitment immediately prior to
giving effect to such assignment; and

(ii) Assignments shall be subject to
the following additional conditions:

     (A)
except in the case of an assignment to a Lender or an Affiliate of a Lender or
an assignment of the entire remaining amount of the assigning Lender’s Term Loan
Commitment or Term Loans, the amount of the Term Loan Commitment or Term Loans
of the assigning Lender subject to each - 52 -

such assignment (determined as of the
date the Assignment and Assumption with respect to such assignment is delivered
to the Administrative Agent) shall not be less than $5,000,000 unless each of
the Borrower and the Administrative Agent otherwise consent, provided
that no such consent of the Borrower shall be required if an Event of Default
has occurred and is continuing;

     (B) each
partial assignment shall be made as an assignment of a proportionate part of all
the assigning Lender’s rights and obligations under this Agreement,
provided that this clause shall not be construed to prohibit the
assignment of a proportionate part of all the assigning Lender’s rights and
obligations in respect of one type of Term Loan Commitment or Term Loans;

     (C) the
parties to each assignment shall execute and deliver to the Administrative Agent
an Assignment and Assumption, together with a processing and recordation fee of
$3,500; and

     (D) the
assignee, if it shall not be a Lender, shall designate to the Administrative
Agent one or more Credit Contacts to whom all syndicate-level information (which
may contain material non-public information about the Loan Parties and their
related parties or their respective securities) will be made available and who
may receive such information in accordance with the assignee’s compliance
procedures and applicable laws, including Federal and state securities laws.

     (iii)
Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of
this Section, from and after the effective date specified in each Assignment and
Assumption the assignee thereunder shall be a party hereto and, to the extent of
the interest assigned by such Assignment and Assumption, have the rights and
obligations of a Lender under this Agreement, and the assigning Lender
thereunder shall, to the extent of the interest assigned by such Assignment and
Assumption, be released from its obligations under this Agreement (and, in the
case of an Assignment and Assumption covering all of the assigning Lender’s
rights and obligations under this Agreement, such Lender shall cease to be a
party hereto but shall continue to be entitled to the benefits of Sections 2.13,
2.14, 2.15 and 10.3) . Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this Section 10.4
shall be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with paragraph (c) of
this Section.

     (iv) The
Administrative Agent, acting for this purpose as an agent of the Borrower, shall
maintain at one of its offices a copy of each Assignment and Assumption
delivered to it and a register for the recordation of the names and addresses of
the Lenders, and the Term Loan Commitment of, and principal amount of the Term
Loan Commitment or Term Loans owing to, each Lender pursuant to the terms hereof
from time to time (the “Register”). The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof
as a Lender hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary. The Register 

- 53 -

shall be available for inspection by
the Borrower and any Lender, at any reasonable time and from time to time upon
reasonable prior notice.

     (v) Upon
its receipt of a duly completed Assignment and Assumption executed by an
assigning Lender and an assignee, the processing and recordation fee referred to
in paragraph (b) of this Section and any written consent to such assignment
required by paragraph (b) of this Section, the Administrative Agent shall accept
such Assignment and Assumption and record the information contained therein in
the Register; provided that if either the assigning Lender or the
assignee shall have failed to make any payment required to be made by it
pursuant to Section 2.5(c), 2.6(d) or (e), 2.7(b), 2.16(d) or 10.3(c), the
Administrative Agent shall have no obligation to accept such Assignment and
Assumption and record the information therein in the Register unless and until
such payment shall have been made in full, together with all accrued interest
thereon. No assignment shall be effective for purposes of this Agreement unless
it has been recorded in the Register as provided in this paragraph.

     (c) (i) Any Lender may, without
the consent of the Borrower or the Administrative Agent, sell participations to
one or more banks or other entities (a “Participant”) in all or a portion
of such Lender’s rights and obligations under this Agreement (including all or a
portion of its Term Loan Commitment and the Term Loans owing to it);
provided that (A) such Lender’s obligations under this Agreement shall
remain unchanged, (B) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations and (C) the Borrower, the
Administrative Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender’s rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that
such agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver
described in the first proviso to Section 10.2(b) that affects such Participant.
Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each
Participant shall be entitled to the benefits of Sections 2.13, 2.14 and 2.15 to
the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to paragraph (b) of this Section. To the extent permitted by
law, each Participant also shall be entitled to the benefits of Section 10.8 as
though it were a Lender, provided such Participant agrees to be subject to
Section 2.16(c) as though it were a Lender.

     (ii) A
Participant shall not be entitled to receive any greater payment under Section
2.13 or 2.15 than the applicable Lender would have been entitled to receive with
respect to the participation sold to such Participant, unless the sale of the
participation to such Participant is made with the Borrower’s prior written
consent. A Participant that would be a Foreign Lender if it were a Lender shall
not be entitled to the benefits of Section 2.17 unless the Borrower is notified
of the participation sold to such Participant and such Participant agrees, for
the benefit of the Borrower, to comply with Section 2.15(e) as though it were a
Lender.

     (d) Any Lender may at any time
pledge or assign a security interest in all or any portion of its rights under
this Agreement to secure obligations of such Lender, including 

- 54 -

without limitation any pledge or assignment to secure
obligations to a Federal Reserve Bank, and this Section shall not apply to any
such pledge or assignment of a security interest; provided that no such
pledge or assignment of a security interest shall release a Lender from any of
its obligations hereunder or substitute any such pledgee or assignee for such
Lender as a party hereto.

     SECTION 10.5. Survival.
All covenants, agreements, representations and warranties made by the Borrower
herein and in the certificates or other instruments delivered in connection with
or pursuant to this Agreement shall be considered to have been relied upon by
the other parties hereto and shall survive the execution and delivery of this
Agreement and the making of any Term Loans, regardless of any investigation made
by any such other party or on its behalf and notwithstanding that the
Administrative Agent or any Lender may have had notice or knowledge of any
Default or incorrect representation or warranty at the time any credit is
extended hereunder, and shall continue in full force and effect as long as the
principal of or any accrued interest on the Term Loans or any fee or any other
amount payable under this Agreement is outstanding and unpaid and so long as the
Term Loan Commitments have not expired or terminated. The provisions of Sections
2.13, 2.14, 2.15 and 10.3 and Article VIII shall survive and remain in full
force and effect regardless of the consummation of the transactions contemplated
hereby, the repayment of the Term Loans and the Term Loan Commitments or the
termination of this Agreement or any provision hereof.

     SECTION 10.6. Counterparts;
Integration; Effectiveness. This Agreement may be executed in counterparts
(and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a
single contract. This Agreement and any separate letter agreements with respect
to fees payable to the Administrative Agent constitute the entire contract among
the parties relating to the subject matter hereof and supersede any and all
previous agreements and understandings, oral or written, relating to the subject
matter hereof. Except as provided in Section 4.1, this Agreement shall become
effective when it shall have been executed by the Administrative Agent and when
the Administrative Agent shall have received counterparts hereof which, when
taken together, bear the signatures of each of the other parties hereto, and
thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart
of a signature page of this Agreement by telecopy shall be effective as delivery
of a manually executed counterpart of this Agreement.

     SECTION 10.7.
Severability. Any provision of this Agreement held to be invalid, illegal
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity, illegality or unenforceability
without affecting the validity, legality and enforceability of the remaining
provisions hereof; and the invalidity of a particular provision in a particular
jurisdiction shall not invalidate such provision in any other jurisdiction.

     SECTION 10.8. Right of
Setoff. If an Event of Default shall have occurred and be continuing, each
Lender and each of its Affiliates is hereby authorized at any time and from time
to time, to the fullest extent permitted by law, to set off and apply any and
all deposits (general or special, time or demand, provisional or final) at any
time held and other obligations at any time owing by such Lender or Affiliate to
or for the credit or the account of the Borrower against any of and all the
obligations of the Borrower now or hereafter existing under this Agreement or

- 55 -

any Hedging Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement or
such Hedging Agreement and although such obligations may be unmatured. The
rights of each Lender under this Section are in addition to other rights and
remedies (including other rights of setoff) which such Lender may have.

     SECTION 10.9. Governing Law;
Jurisdiction; Consent to Service of Process.

     (a) This Agreement shall be
construed in accordance with and governed by the law of the State of New
York.

     (b) The Borrower hereby
irrevocably and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of the Supreme Court of the State of New York sitting
in New York County and of the United States District Court of the Southern
District of New York, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Agreement, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Agreement shall affect any right that the
Administrative Agent or any Lender may otherwise have to bring any action or
proceeding relating to this Agreement against the Borrower or its properties in
the courts of any jurisdiction.

     (c) The Borrower hereby
irrevocably and unconditionally waives, to the fullest extent it may legally and
effectively do so, any objection which it may now or hereafter have to the
laying of venue of any suit, action or proceeding arising out of or relating to
this Agreement in any court referred to in paragraph (b) of this Section. Each
of the parties hereto hereby irrevocably waives, to the fullest extent permitted
by law, the defense of an inconvenient forum to the maintenance of such action
or proceeding in any such court.

     (d) Each party to this Agreement
irrevocably consents to service of process in the manner provided for notices in
Section 10.1. Nothing in this Agreement will affect the right of any party to
this Agreement to serve process in any other manner permitted by law.

     SECTION 10.10. WAIVER OF JURY
TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING
DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER
THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR
ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS
AND CERTIFICATIONS IN THIS SECTION.

- 56 -

     SECTION 10.11. Headings.
Article and Section headings and the Table of Contents used herein are for
convenience of reference only, are not part of this Agreement and shall not
affect the construction of, or be taken into consideration in interpreting, this
Agreement.

     SECTION 10.12.
Confidentiality.

     (a) Each of the Administrative
Agent and the Lenders agrees to maintain the confidentiality of the Information
(as defined below), except that Information may be disclosed (a) to its and its
Affiliates’ directors, officers, employees and agents, including accountants,
legal counsel and other advisors (it being understood that the Persons to whom
such disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential), (b) to the
extent requested by any regulatory authority, (c) to the extent required by
applicable laws or regulations or by any subpoena or similar legal process, (d)
to any other party to this Agreement, (e) in connection with the exercise of any
remedies hereunder or any suit, action or proceeding relating to this Agreement
or the enforcement of rights hereunder, (f) subject to an agreement containing
provisions substantially the same as those of this Section, to (i) any assignee
of or Participant in, or any prospective assignee of or Participant in, any of
its rights or obligations under this Agreement or (ii) any actual or prospective
counterparty (or its advisors) to any swap or derivative transaction relating to
the Borrower and its obligations, (g) with the consent of the Borrower or (h) to
the extent such Information (i) becomes publicly available other than as a
result of a breach of this Section or (ii) becomes available to the
Administrative Agent or any Lender on a nonconfidential basis from a source
other than the Borrower. For the purposes of this Section, “Information”
means all information received from the Borrower relating to the Borrower or its
business, other than any such information that is available to the
Administrative Agent or any Lender on a nonconfidential basis prior to
disclosure by the Borrower; provided that, in the case of information
received from the Borrower after the date hereof, such information is clearly
identified at the time of delivery as confidential. Any Person required to
maintain the confidentiality of Information as provided in this Section shall be
considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such
Information as such Person would accord to its own confidential information.

     (b) EACH LENDER ACKNOWLEDGES THAT
INFORMATION AS DEFINED IN SECTION 10.12(a) FURNISHED TO IT PURSUANT TO THIS
AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC INFORMATION CONCERNING THE BORROWER
AND ITS RELATED PARTIES OR THEIR RESPECTIVE SECURITIES, AND CONFIRMS THAT IT HAS
DEVELOPED COMPLIANCE PROCEDURES REGARDING THE USE OF MATERIAL NON-PUBLIC
INFORMATION AND THAT IT WILL HANDLE SUCH MATERIAL NON-PUBLIC INFORMATION IN
ACCORDANCE WITH THOSE PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE
SECURITIES LAWS.

     (c) ALL INFORMATION, INCLUDING
REQUESTS FOR WAIVERS AND AMENDMENTS, FURNISHED BY THE BORROWER OR THE
ADMINISTRATIVE AGENT PURSUANT TO, OR IN THE COURSE OF ADMINISTERING, THIS
AGREEMENT WILL BE SYNDICATE-LEVEL INFORMATION, WHICH MAY CONTAIN MATERIAL 

- 57 -

NON-PUBLIC INFORMATION ABOUT THE LOAN PARTIES AND THEIR RELATED
PARTIES OR THEIR RESPECTIVE SECURITIES. ACCORDINGLY, EACH LENDER REPRESENTS TO
THE BORROWER AND THE ADMINISTRATIVE AGENT THAT IT HAS IDENTIFIED A CREDIT
CONTACT WHO MAY RECEIVE INFORMATION THAT MAY CONTAIN MATERIAL NON-PUBLIC
INFORMATION IN ACCORDANCE WITH ITS COMPLIANCE PROCEDURES AND APPLICABLE LAW.

     SECTION 10.13. Interest Rate
Limitation. Notwithstanding anything herein to the contrary, if at any time
the interest rate applicable to the Term Loans, together with all fees, charges
and other amounts which are treated as interest on the Term Loans under
applicable law (collectively the “Charges”), shall exceed the maximum
lawful rate (the “Maximum Rate”) which may be contracted for, charged,
taken, received or reserved by the Lender holding such Term Loan in accordance
with applicable law, the rate of interest payable in respect of such Term Loan
hereunder, together with all Charges payable in respect thereof, shall be
limited to the Maximum Rate and, to the extent lawful, the interest and Charges
that would have been payable in respect of such Term Loan but were not payable
as a result of the operation of this Section shall be cumulated and the interest
and Charges payable to such Lender in respect of other Term Loans or periods
shall be increased (but not above the Maximum Rate therefor) until such
cumulated amount, together with interest thereon to the date of repayment, shall
have been received by such Lender.

     SECTION 10.14. Know Your
Customer Requirements. Each Lender that is subject to “know-your-customer”
requirements of any Governmental Authority, hereby notifies the Borrower that
pursuant to such requirements, it is required to obtain, verify and record
information that identifies the Borrower, which information includes the name
and address of the Borrower and other information that will allow such Lender to
identify the Borrower in accordance with such requirements.

ASSIGNMENT AND ASSUMPTION

     This Assignment and Assumption
(the “Assignment and Assumption”) is dated as of the Effective Date set
forth below and is entered into by and between [Insert name of Assignor]
(the “Assignor”) and [Insert name of Assignee] (the
“Assignee”). Capitalized terms used but not defined herein shall have the
meanings given to them in the Amended and Restated Credit Agreement
identified below (as amended, the “Amended and Restated Credit
Agreement”), receipt of a copy of which is hereby acknowledged by the
Assignee. The Standard Terms and Conditions set forth in Annex 1 attached hereto
are hereby agreed to and incorporated herein by reference and made a part of
this Assignment and Assumption as if set forth herein in full.

     For an agreed consideration, the
Assignor hereby irrevocably sells and assigns to the Assignee, and the Assignee
hereby irrevocably purchases and assumes from the Assignor, subject to and in
accordance with the Standard Terms and Conditions and the Amended and Restated
Credit Agreement, as of the Effective Date inserted by the Administrative Agent
as contemplated below (i) all of the Assignor’s rights and obligations in its
capacity as a Lender under the Amended and Restated Credit Agreement and any
other documents or instruments delivered pursuant thereto to the extent related
to the amount and percentage interest identified below of all of such
outstanding rights and obligations of the Assignor under the Term Loan and (ii)
to the extent permitted to be assigned under applicable law, all claims, suits,
