ARTICLE II

REPRESENTATIONS AND WARRANTIES

 

The Sponsor represents
and warrants to the Collateral Agent (for the benefit of the Secured Parties)
that:

 

2.01                           Representations.  The Sponsor’s representations and warranties
set forth in Article IV of the Completion Agreement are true and correct
on and as of the date hereof.

 

2.02                           Good Title; Valid Security Interests.  Subject only to the security interests created
hereby and any Sponsor Permitted Liens, it has good title to all rights and
property in which it purports to create a security interest hereunder.  This Agreement creates in favor of the
Collateral Agent for the benefit of the Secured Parties the security interests
purported to be created by it under Article III hereof and such security
interests constitute, under applicable law, fully perfected first priority
security interests in the Sponsor Collateral subject only to Sponsor Permitted
Liens which are granted priority on a mandatory basis under applicable
Government Rules.

 

2.03                           Names, Etc.  The full and correct legal name, type of
organization, jurisdiction of organization, organizational ID number (if applicable)
and mailing address of the Sponsor as of the date hereof are correctly set
forth in Annex 1.  Annex 1
correctly specifies (a) the place of business of the Sponsor or, if the
Sponsor has more than one place of business, the location of the chief executive
office of the Sponsor and (b) each location where any financing statement
naming the Sponsor as debtor is currently on file.  The Sponsor has not (a) within the
period of four months prior to the date hereof, changed its location (as
defined in Section 9-307 of the UCC), (b) except as specified in
Annex 1, heretofore changed its name, or 

 

4

 

(c) prior to the date hereof become a “new debtor”
(as defined in Section 9-102(a)(56) of the UCC) with respect to a
currently effective security agreement previously entered into by any other
Person.

 

2.04                           Proper Legal Form.  This Agreement is in proper legal form under
the laws of the Cayman Islands for the enforcement thereof against the Sponsor
under the laws of the Cayman Islands and if this Agreement were stated to be
governed by such law, it would constitute the legal, valid and binding
obligation of the Sponsor under such law, enforceable in accordance with its
terms subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting
creditors’ rights and to general equity principles; and to ensure the legality,
validity, enforceability or admissibility in evidence of this Agreement in the
Cayman Islands, it is not necessary that this Agreement or any other document
be filed or recorded with any court or other authority in the Cayman Islands or
that any stamp or similar tax be paid on or in respect of this Agreement
(except for (i) those specified in the legal opinions delivered in
satisfaction of the conditions precedent referred to in Section 11.02(h) of
the Common Security Agreement which are to be paid following the Closing Date
but prior to the Initial Disbursement Date, (ii) those which are
immaterial and of a ministerial nature and (iii) those payable in the
Cayman Islands as specified in the legal opinion of Cayman counsel as being
payable in connection with enforcement in the Cayman Islands).  The laws of the Cayman Islands do not provide
for or require any filing, recording or registration of a security interest in
the right, title and interest of the Sponsor in any of the Sponsor Collateral
as a condition of obtaining priority over a creditor that has acquired a Lien
thereon or over a receiver in bankruptcy.

 

ARTICLE III

SPONSOR COLLATERAL

 

As collateral security
for the payment in full when due (whether at stated maturity, by acceleration
or otherwise) and performance of the Secured Obligations, the Sponsor hereby
pledges and grants to the Collateral Agent for the benefit of the Secured
Parties a security interest in the following (all of the property described in
Sections 3.01(a), 3.02(a), 3.03(a) and (c), and 3.04(a) and all
Proceeds thereof, being collectively referred to herein as “Sponsor Collateral”):

 

3.01                           Shares of Apex Luxembourg.

 

(a)                                  All
right, title and interest which the Sponsor has or may at any time hereafter
acquire in and to (i) the shares of Apex Luxembourg (the “Apex Luxembourg Shares”), (ii) all
other shares, securities or other property constituting or representing a right
to receive a dividend on the Apex Luxembourg Shares or constituting or
representing a right to receive a distribution or return of capital upon or in
respect of the Apex Luxembourg Shares or constituting or representing warrants
or any subscription or other purchase rights with respect to the Apex
Luxembourg Shares, and (iii) any other interest in Apex Luxembourg which
may become or be converted into an equity interest in Apex Luxembourg.  The Sponsor shall deliver to the Collateral
Agent the certificates representing the Apex Luxembourg Shares on or prior to
the Closing Date and, promptly following receipt, shall deliver to the
Collateral Agent certificates or other relevant documentation representing any
of such other shares, securities, 

 

5

 

property, warrants, subscriptions, interests or
rights, together in each case with stock powers duly executed by it in blank,
to be held by the Collateral Agent for the benefit and on behalf of the Secured
Parties pursuant to the pledge made hereby. 
The Sponsor agrees that it shall not permit the Organizational Documents
of Apex Luxembourg to be amended or modified in any manner that would deprive
the holders of the Apex Luxembourg Shares of control of Apex Luxembourg.

 

(b)                                 On
or prior to the Initial Disbursement Date, the Sponsor shall, as security for
the Secured Obligations, make or cause to be made any filings or recordations,
give or cause to be given any notices and take or cause to be taken any other
actions as may be necessary in the State of New York, Washington, D.C., the
Cayman Islands, Luxembourg and any other jurisdiction necessary to perfect the
pledge of Apex Luxembourg Shares and all such other shares, securities,
property, warrants, subscriptions, interests and rights in Apex
Luxembourg.  The Sponsor hereby promises
to deliver in pledge to the Collateral Agent any Apex Luxembourg Shares and all
such other shares, securities, property, warrants, subscriptions, interests and
rights in Apex Luxembourg which it may acquire after the Closing Date, promptly
upon the receipt thereof, and to make or cause to be made any filings,
registrations or recordations, give or cause to be given any notices and take
or cause to be taken any other actions as may be necessary to perfect the
pledge of such Apex Luxembourg Shares and all such other shares, securities,
property, warrants, subscriptions, interests and rights in Apex Luxembourg.  The Sponsor shall defend, all at its own cost and expense, its title to, and the

give, execute, deliver, file, record, authorize or obtain all such financing
statements, continuation statements, notices, instruments, documents,
agreements or consents or other papers as may be necessary or desirable in the
judgment of the Collateral Agent (subject to Section 7.12) to create,

interests in the Sponsor Collateral granted pursuant hereto or to enable the
Collateral Agent to exercise and enforce its rights hereunder with respect to

authorize or permit to be filed or to be on file, in any jurisdiction, any

other than the Collateral Agent to have “control” (as defined in Section 9-104,
9-105, 9-106 or 9-107 of the UCC) of any part of the Sponsor Collateral.

 

5.03                           Preservation of Rights.  The Collateral Agent shall not be required to
take steps necessary to preserve any rights against prior parties to any of the

and the payment in full of the Secured Obligations, the Sponsor shall remain
liable for any deficiency.

to or authorize any modification of the terms of any item of Sponsor Collateral
that would result in a change thereof from one Uniform Commercial Code category

or diminution of priority for, the security interests created hereunder in such

Secured Parties arising by reason of the fact that the price at which the
Sponsor Collateral may have been sold at such a private sale was less than the
price that might have been obtained at a public sale or was less than the

accepts the first offer received and does not offer the Sponsor Collateral to
more than one offeree.

7.05                           Benefits of Agreement.  Nothing in this Agreement, express or
implied, shall give to any Person, other than the parties hereto and the
Secured Parties and their successors and permitted assigns under the applicable
Financing Documents, any benefit or any legal or equitable right or remedy

7.06                           Counterparts.  This Agreement may be executed in any number
of counterparts and by the different parties hereto on separate counterparts,

7.07                           Jurisdiction, Service of Process and Venue.

 

(a)                                  The
Sponsor hereby irrevocably consents and agrees that any legal action, suit or
proceeding against it with respect to its obligations, liabilities or any other
matter under or arising out of or in connection with this Agreement may be
brought in any Federal or State court located in the Borough of Manhattan, The
City of New York, and hereby irrevocably accepts and submits to the
non-exclusive jurisdiction of each such court with respect to any such action,
suit or proceeding.  Each party hereto
waives any objection which it may now or hereafter have to the laying of venue
of any of the aforesaid actions, suits or proceedings brought in any such court
and hereby further waives and agrees not to plead or claim in any such court
that any such action, suit or proceeding brought therein has been brought in an
inconvenient forum.

 

(b)                                 The
Sponsor agrees that a final judgment against it in any action, suit or
proceeding taken in a New York court or New York Federal court in accordance
with clause (a) shall be conclusive and may be enforced in any
jurisdiction by suit on the judgment, a certified copy of which judgment shall
be conclusive evidence thereof, or by any other means provided by applicable
law.

 

(c)                                  The
Sponsor hereby irrevocably appoints CT Corporation System, with offices at the
date of this Agreement at 111 8th Avenue, New York, New York 10011, as its 

 

17

 

authorized agent on which any and all legal process
may be served in any such action, suit or proceeding brought in any Federal or
State court located in the Borough of Manhattan, The City of New York.  The Sponsor agrees that service of process in
respect of it upon such agent, together with written notice of such service
given as provided in Section 7.04, shall be deemed to be effective service
of process upon it in any such action, suit or proceeding.  The Sponsor agrees that the failure of such
agent to give notice to it of any such service shall not impair or affect the
validity of such service or any judgment rendered in any action, suit or
proceeding based thereon.  If for any
reason such agent shall cease to be available to act as such, the Sponsor
agrees to designate a new agent in the Borough of Manhattan, The City of New
York, on the terms and for the purposes of this Section 7.07.  Nothing herein shall be deemed to limit the
ability of the Collateral Agent to serve any such legal process in any other
manner permitted by applicable law or to obtain jurisdiction over the Sponsor
or bring actions, suits or proceedings against it in such other jurisdictions,
and in such manner, as may be permitted or required by applicable law.

 

(d)                                 To
the extent that the Sponsor has or hereafter may acquire any immunity from
jurisdiction of any court or from any legal process (whether through service of
notice, attachment prior to judgment, attachment in aid of execution,
execution, sovereign immunity or otherwise) with respect to itself or its
property, the Sponsor hereby irrevocably waives such immunity, to the fullest
extent permitted by law, in respect of its obligations under this Agreement.

 

7.08                           Amendments, Etc.  The terms of this Agreement may amended only
by an agreement in writing signed by each party hereto; provided that the amendment of a term
defined by reference to the Common Security Agreement shall be binding on the
parties hereunder if such amendment has been approved as provided in Section 15.18
of the Common Security Agreement.

 

7.09                           No Waiver. 
No failure on the part of the Collateral Agent or any Secured Party to
exercise, and no course of dealing with respect to, and no delay in exercising,
any right, power or remedy hereunder shall operate as a waiver thereof; nor
shall any single or partial exercise by the Collateral Agent or any Secured
Party of any right, power or remedy hereunder preclude any other or further
exercise thereof or the exercise of any other right, power or remedy.  The remedies herein are cumulative and are
not exclusive of any remedies provided by law.

 

7.10                           Successors and Assigns.  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns.

 

7.11                           Expenses.

Agent for all reasonable costs and expenses of the Secured Parties and the
Collateral Agent (including, without limitation, the reasonable fees and
expenses of legal counsel) in connection with (a) any Sponsor Default or
Event of Default and any enforcement or collection proceeding resulting
therefrom, including, without limitation, all manner of participation in or
other involvement with (i) bankruptcy, insolvency, receivership,

proceedings and (iii) workout, restructuring or other negotiations or
proceedings (whether or not the workout, restructuring or transaction
contemplated thereby is consummated) and (b) the enforcement of this Section 7.11.

 

18

 

7.12                           Collateral Agent Protections.  The rights, benefits, privileges and
protections conferred upon the Collateral Agent pursuant to Article XIII
of the Common Security Agreement are expressly incorporated herein by reference
and shall extend to the Collateral Agent hereunder as if such rights, benefits,
privileges and protections were set forth in full herein.

 

7.13                           No Consequential Damages.  Neither the Sponsor nor any Secured Party
shall assert any claim against the Sponsor or any Secured Party, as the case
may be, on any theory of liability, for any lost profits or special, indirect
or consequential damages or (to the fullest extent lawful) any punitive damages
arising out of, in connection with, or as a result of, this Agreement or any
other Financing Document (except as the same may be asserted by a third party
in respect of any claim for which a Secured Party is indemnified hereunder),
and each of the parties hereto hereby forever waives, releases and agrees not
to sue upon any claim for any such lost profits or special, indirect,
consequential or (to the fullest extent lawful) punitive damages, whether or
not accrued and whether or not known or suspected to exist in its favor.

ARTICLE III

GUARANTEE

 

3.01         Guarantee.

 

(a)           The
Sponsor, as a primary obligor and not merely as a surety, unconditionally and
irrevocably guarantees to the Collateral Agent, the Administrative Agent, the
Technical Agent, each Senior Lender and each Hedge Bank and their respective
successors and assigns the full and punctual payment by (i) the Borrower
of all Secured Debt Obligations and (ii) Apex Metals of all obligations of
Apex Metals incurred under the Mandatory Metals Hedge Agreements (including all
Mandatory Metals Hedge Transactions executed thereunder) including all
obligations of payment and performance thereunder (such obligations being
herein collectively called the “Apex Metals
Obligations”) that, in any such case, are or become due and payable
prior to Completion, when and as the same shall become due and payable, whether
at maturity, upon acceleration, early termination or otherwise (subject to any
exclusions or applicable grace periods), according to their terms (such
obligations being herein collectively called the “Guaranteed Obligations”). 
In case of the failure of any Guaranteed Obligor to so pay any
Guaranteed Obligation, the Sponsor agrees to make such payment in full
forthwith upon demand, in Dollars, in cash, at such times and in the same
manner as required of such Guaranteed Obligor.

 

(b)           The
Sponsor agrees that its Completion Guarantee shall be unconditional and
irrevocable, irrespective of the invalidity or unenforceability of the
Guaranteed Obligations, the absence of any action to enforce the same, any
waiver or consent by any Senior Lender or any Hedge Bank with respect to any
provision of this Agreement, the Common Security Agreement or any of the other
Financing Documents, the recovery of any judgment against any Guaranteed
Obligor or any action to enforce the same, the insolvency or bankruptcy of any
Guaranteed Obligor or any other circumstance which might otherwise constitute a
legal or equitable claim, right, discharge or defense of a guarantor or surety
(other than complete payment in full in Dollars of the Guaranteed Obligations)
or otherwise impair the right of the Collateral Agent, the Administrative
Agent, the Technical Agent, any Senior Lender or any Hedge Bank to enforce the
obligations of the Sponsor hereunder. 
The Sponsor waives, to the extent permitted under applicable law,
diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of any Guaranteed Obligor, any right to
require a proceeding first against any Guaranteed Obligor, any requirement that
the Collateral Agent, the Administrative Agent, the Technical Agent, any Hedge
Bank or any Senior Lender exhaust any right, power or remedy or proceed against
any Guaranteed Obligor or against any other Person under any guarantee of, or
security for any Guaranteed Obligation, protest, notice (including, without
limitation, notice of acceptance of this Completion Guarantee and notice of any
liability to which it may apply) and all demands whatsoever and agrees, that
its 

 

3

 

Completion
Guarantee shall remain in full force and effect and will not be discharged
except by complete payment in full, in cash and in Dollars of the Guaranteed
Obligations.  In the event that any
payment to the Senior Lenders or Hedge Banks in respect of any Guaranteed
Obligation is rescinded or must otherwise be returned for any reason
whatsoever, the Sponsor shall remain liable for such Guaranteed Obligation to
the extent provided herein as if such payment had not been made (and if the
Sponsor’s obligations under the Completion Guarantee have been terminated in
accordance with this Agreement, such obligations shall be reinstated to the
extent necessary for the Sponsor to comply with the foregoing provisions of
this sentence).  The Sponsor agrees that
it will pay or reimburse the Collateral Agent, the Administrative Agent, the
Technical Agent, each Senior Lender and each Hedge Bank on demand for all
reasonable and documented costs and expenses (including, without limitation,
reasonable and documented fees and disbursements of counsel) incurred by the
Collateral Agent, the Administrative Agent, the Technical Agent, such Senior
Lender or such Hedge Bank, as the case may be, in connection with the
rescission or restoration of the Completion Guarantee, including any such costs
and expenses incurred in defending against any claim alleging that any payment
constituted a preference, fraudulent transfer or similar payment under any bankruptcy,
insolvency or similar law.

 

(c)           The
Sponsor agrees that the Senior Lenders or the Hedge Banks may at any time and
from time to time, either before or after the maturity thereof, without notice
to or further consent of the Sponsor, extend the time of payment of, exchange
or surrender or fail to perfect collateral for, or renew, any of the Guaranteed
Obligations owed to it, and may also make any agreement with any Guaranteed
Obligor for the extension, renewal, payment, compromise, discharge or release thereof,
in whole or in part, or for any modification of the terms thereof or of any
agreement between Senior Lenders or the Hedge Banks and any Guaranteed Obligor,
without in any way impairing or affecting the Completion Guarantee.

 

3.02         Payments Free and Clear of Taxes, Etc.

 

(a)           Except
as required by law, any and all payments made by the Sponsor under the
Completion Guarantee to the Collateral Agent, the Administrative Agent, the
Technical Agent, any Senior Lender or any Hedge Bank shall be made free and clear
of and without deduction or withholding for any and all present or future
withholding, income, stamp and other taxes, levies, imposts, deductions, duties
or similar charges imposed by the government of the Cayman Islands or any
political subdivision or taxing authority thereof or therein or by any other
jurisdiction from or through which payments are made (other than any of the
foregoing imposed on the net income of the Collateral Agent, the Administrative
Agent, the Technical Agent, any of the Senior Lenders or any Hedge Bank, or any
franchise or other tax imposed on the Collateral Agent, the Administrative
Agent, the Technical Agent, any of the Senior Lenders or any Hedge Bank, by a
jurisdiction by virtue of the Collateral Agent’s, the Administrative Agent’s,
such Senior Lenders’ or such Hedge Banks’ connection with such jurisdiction
other than a connection arising solely under this Agreement, the Common
Security Agreement or any other Financing Document) (such taxes herein referred
to as “Taxes”).  If the Sponsor shall be required by law to
deduct any Taxes from or in respect of any payment under the Completion
Agreement to the Collateral Agent, the Administrative Agent, the Technical
Agent, any Senior Lender or any Hedge Bank, (i) such payment shall be
increased so that, after 

 

4

 

all required
deductions for Taxes have been made, such payment shall not be less than the
amount that would have been paid by the Sponsor had no such deductions for
Taxes been required and made, (ii) the Sponsor shall make such deductions
and (iii) the Sponsor shall pay the full amount deducted to the relevant
taxing authority or other authority in accordance with applicable law.  If the Collateral Agent, the Administrative
Agent, the Technical Agent, any Senior Lender or any Hedge Bank pays any such
Taxes, the Sponsor shall, upon demand by the Collateral Agent, the
Administrative Agent, the Technical Agent, such Senior Lender or such Hedge
Bank and submission of reasonable documentary evidence of such payment,
reimburse the Collateral Agent, the Administrative Agent, the Technical Agent,
such Senior Lender or such Hedge Bank for such payments.  The Collateral Agent, the Administrative Agent,
the Technical Agent, each Senior Lender and each Hedge Bank shall use its
reasonable efforts to avoid or mitigate the need for any additional payments by
the Sponsor under this Section, provided
that the Collateral Agent, the Administrative Agent, the Technical
Agent, such Senior Lender or such Hedge Bank shall not be required hereunder to
take any action which is commercially disadvantageous to it or which it
determines violates or is otherwise impermissible under the regulatory
requirements to which it is subject.  If
so requested, the Sponsor shall furnish to the Collateral Agent and the
Administrative Agent original or certified copies of tax receipts in respect of
any Taxes withheld as required under this Section 3.02 as promptly as
reasonably practicable.

 

(b)           Each
Senior Lender, each Hedge Bank, the Administrative Agent and the Collateral
Agent shall notify the Sponsor if it shall have actual knowledge of any event
or circumstances occurring after the date of this Agreement which will give
rise to a payment obligation to it under clause (a) of this Section 3.02
as promptly as practicable after it obtains actual knowledge thereof and of its
applicability to payments due under this Agreement.  Such affected Secured Party will inform the
Sponsor in writing of the basis and amount of each payment obligation under
clause (a) of this Section 3.02. 
The failure of such affected Secured Party to provide such notice will
not affect the obligation of the Sponsor under its Completion Guarantee or
under this Section 3.02 or give rise to a claim on, or liability of, such
affected Secured Party.

 

(c)           The
obligations of the Sponsor under clause (a) and (d) of this Section 3.02
shall survive the payment, prepayment or assignment of Guaranteed Obligations
and the termination of this Agreement.

 

(d)           The
Sponsor agrees to pay upon demand any present or future stamp or documentary
taxes or any other excise or property taxes, charges or similar levies which
arise from any payment or purchase made under the Completion Guarantee or from
the execution, delivery or registration of, or otherwise with respect to, the
Completion Guarantee or this Agreement (other than taxes that would be excluded
from the definition of “Taxes” in clause (a) of this Section 3.02
pursuant to the parenthetical phrase in the first sentence of such clause (a)).

 

5

 

3.03         Subrogation.  The Sponsor hereby agrees that until (a) the
payment and satisfaction in full of all the Guaranteed Obligations and (b) the
expiration and termination of the Senior Loan Commitments of the Senior Lenders
under the Senior Loan Agreements and the termination of all outstanding
Mandatory Metals Hedge Transactions, it shall not exercise any right or remedy
arising by reason of any performance by it of its guarantees in Section 3.01,
whether by subrogation or otherwise, against the Borrower or any other
guarantor of any of the Guaranteed Obligations or any security for any of the
Guaranteed Obligations.

 

ARTICLE IV

REPRESENTATIONS AND WARRANTIES OF THE SPONSOR

Collateral Agent and the Administrative Agent for and on behalf of the Senior
Lenders and the Hedge Banks that:

 

(a)           Organization.  The Sponsor (i) is incorporated and validly

this Agreement and the other Financing Documents to which it is a party, except
where the failure to so qualify or be in good standing could not reasonably be
expected to have a Material Adverse Effect;

 

(b)           Ownership
of the Borrower.  At the date
hereof, (i) the Sponsor owns 100% of the issued and outstanding share
capital of Apex Luxembourg; (ii) Apex Luxembourg owns 100% of the issued

and authority to enter into each Transaction Document to which it is a party
and to incur and perform its obligations provided for herein and therein;

 

(d)           Binding
Agreements.  Each Transaction
Document to which the Sponsor is a party which has been executed and delivered
by the Sponsor on or prior to the date hereof, has been duly authorized,
executed and delivered by it and constitutes its legal, valid and binding
obligation enforceable in accordance with its terms, subject to bankruptcy,
insolvency, fraudulent transfer, reorganization, moratorium and similar laws of
general applicability relating to or affecting creditors’ rights and to general
equity principles;

 

6

 

(e)           Consents
and Approvals.  All
Authorizations and Government Approvals which are necessary for (i) the
execution and delivery by the Sponsor of this Agreement and the other Financing
Documents and (ii) the performance of its obligations hereunder and
thereunder have been obtained and are in full force and effect (except for
those specified in the legal opinions delivered in satisfaction of the
conditions precedent referred to in Section 11.02(h) of the Common Security
Agreement which are to be obtained following the Closing Date but prior to the
Initial Disbursement Date), and no other action by, and no notice to or filing
with, any Governmental Authority or other Person is required for such
execution, delivery or performance and all fees and taxes required for the
legality or enforceability of such documents have been paid (except for (i) those

precedent referred to in Section 11.02(h) of the Common Security
Agreement which are to be paid following the Closing Date but prior to the
Initial Disbursement Date, (ii) those which are immaterial and of a
ministerial nature and (iii) those payable in the Cayman Islands as
specified in the legal opinion of Cayman counsel as being payable in connection
with enforcement in the Cayman Islands);

 

(f)            No
Conflicts.  The execution,
delivery and performance by the Sponsor of each of the Financing Documents to
which it is or is intended to be a party and the consummation of the
transactions contemplated thereby do not and will not (i) violate any
provision of its Organizational Documents, any Authorization, any Government Rule or
any Government Approval applicable to the Project or the Sponsor, (ii) conflict
with, result in a breach of or constitute a default under any Financing
Document or any mortgage, indenture, loan, credit agreement or other agreement
to which the Sponsor is a party or by which it or its property may be bound or
affected in any material respect, or (iii) result in, or create any Lien
(other than a Sponsor Permitted Lien) upon or with respect to any of the

(g)           No

those which have been disclosed in writing to the Senior Lenders on or prior to
the date hereof or those which could not reasonably be expected to result in a
Material Adverse Effect.  There is no
existing default by the Sponsor under any applicable order, writ, injunction or
decree or other decision of any Governmental Authority or any arbitrator;

 

(h)           Project
Information.  As of the date
hereof and the Initial Disbursement Date, the Project Information relevant to
the Sponsor and other information provided by or on behalf of the Sponsor in
writing to the Senior Lenders (as may have been superseded, modified or
corrected by later information provided in writing by or on behalf of the
Sponsor in accordance with the Financing Documents), considered as a whole,
does not contain any material misrepresentation or misstatement (or omit any
material fact or circumstance necessary in order to make the information
contained therein not misleading); provided that,
the Sponsor’s sole representation with respect to projections, estimates or
other expressions of view as to future circumstances set out in the Project
Information shall be that such projections, estimates or other expressions of 

 

7

 

view as to future circumstances (i) were prepared
in good faith and with due care and (ii) were based on reasonable
assumptions as to all factual and legal matters material to the estimates
therein as of their respective date(s) of delivery;

 

(i)            No
Immunity.  The Sponsor is
subject to civil and commercial law with respect to its obligations under each
of the Financing Documents to which it is a party.  The execution, delivery and performance by
the Sponsor of each of the Financing Documents to which it is a party
constitute private and commercial acts rather than public or governmental
acts.  Neither the Sponsor, nor any of
its assets, is entitled to any right of immunity in any jurisdiction from suit,
court jurisdiction, judgment, attachment (whether before or after judgment),
set-off or execution of a judgment or from any other legal process or remedy
relating to the obligations of the Sponsor under any of the Financing Documents
to which it is a party;

 

(j)            Taxes.  The Sponsor has filed or caused to be filed
all tax returns required to be filed by it, and has paid all taxes shown to be
due and payable on such returns, or on any assessments made against it or any
of its properties, and all other taxes, assessments, fees, liabilities or other
charges imposed on it or on its properties by any Governmental Authority, in
each case after giving effect to any applicable extensions, except for any such
taxes, assessments, fees, liabilities and other charges (i) the payment of
which is being contested in good faith and by appropriate proceedings and for
which adequate reserves are being maintained in accordance with U.S. GAAP and
Applicable Accounting Principles or (ii) the failure of which to file or
pay could not reasonably be expected to have a Material Adverse Effect.  As of the date hereof, there are no material
disputes pending or, to its knowledge, threatened, between the Sponsor and any
Governmental Authority relating to taxes;

 

(k)           Ranking.  The obligations of the Sponsor under this
Agreement will at all times rank pari passu
in right of payment with or senior in right of payment to all other unsecured
obligations of the Sponsor, other than those which have priority under the law
of the Cayman Islands;

 

(l)            Financial
Condition.  The financial
statements of the Sponsor delivered in accordance with Section 4.02 of the
Sponsor Pledge Agreement are true, complete and correct and fairly present in
all material respects the financial condition and results of operations of the
Sponsor as at the end of, and for, such fiscal year or each fiscal quarter, as
the case may be, in accordance with U.S. GAAP consistently applied (subject, in
the case of quarterly financial statements, to normal year-end adjustments and
the absence of notes).  The Sponsor does
not have as of the date of such financial statements any material contingent
liabilities, liabilities for taxes, unusual forward or long-term commitments or
unrealized or anticipated losses from any unfavorable commitments required to
be included or noted in financial statements prepared in accordance with U.S.
GAAP, except (i) as referred to or reflected or provided for in such
financial statements or, in the case of the financial statements delivered
pursuant to Section 11.01(h) of the Common Security Agreement, as
arising solely from the execution and delivery of the Financing Documents or (ii) as
notified in writing to the Administrative Agent 

 

8

 

concurrently with the delivery of such financial
statements.  There has been no material
adverse change in the business, assets, operations or condition, financial or
otherwise, of the Sponsor from that set forth in such financial statements (as
supplemented by any information delivered therewith pursuant to the preceding
sentence, if any) as of the date thereof; and

 

(m)          Dedicated
Cash.  As of the date hereof,
the Sponsor (i) has available to it Dedicated Cash in an amount of not
less than $51,069,000 and (ii) has deposited $10,893,780 of such amount in
an identified securities account maintained with The Bank of New York as
collateral agent and securities intermediary with respect to the Convertible
Notes bearing interest at 4.0% (the “Escrow
Account”) for the purpose of paying interest on such Convertible
Notes when the same becomes due and payable. 
As of the Initial Disbursement Date, the Sponsor will have deposited
$9,855,180 in an identified securities account maintained with an institution
and on terms reasonably acceptable to the Sponsor and the Administrative Agent
(the “Additional Escrow Account”)
for the purpose of paying interest on any of the Convertible Notes when the
same becomes due and payable.

 

(n)           Share
Funding.  The Sponsor has
authorized but not yet issued a sufficient number of common shares of the
Sponsor to permit the Sponsor to fund the Share Funding Amount in accordance
with Section 5.05 hereof.

5.02         Pari Passu Obligations.  The Sponsor shall ensure that its obligations
under each of this Agreement, the Transfer Restrictions Agreement, the Sponsor

bankruptcy, insolvency or other laws of general application affecting creditors’
rights generally.

 

5.03         Contingent Support Deficiencies.  In the event that at any time a Contingent
Support Deficiency exists as identified in a Cost to Complete Certificate, the

not presented a plan, the date on which such plan was due to be presented.  The Sponsor shall submit additional
Acceptable Funding Plans in the event that additional funds are required to
cause the Contingent Support Requirement to be satisfied without regard as to
whether the Sponsor may be currently implementing an Acceptable Funding Plan
with respect to a previously identified Contingent Support Deficiency.

 

5.04         Available Cash.  The Sponsor shall (a) expend its
Available Cash in material compliance with the Sponsor Budget and (b) following
the Initial Disbursement Date, upon the release of funds by the issuer of

Contractor on behalf of the Borrower a number of shares in the Sponsor having a
value as determined under the EPCM Contract of up to $4,000,000 on the date

7.10         Consent to Jurisdiction.

 

(a)           The
Sponsor hereby irrevocably consents and agrees, for the benefit of each other

obligations, liabilities or any other matter under or arising out of or in
connection with this Agreement may be brought in any Federal or State court
located in the Borough of Manhattan, The City of New York (a “New York court”), and hereby irrevocably
accepts and submits to the non-exclusive jurisdiction of each such New York

action, suit or proceeding.  The Sponsor
waives any objection which it may now or hereafter have to the laying of venue
of any of the aforesaid actions, suits or proceedings brought in any such New
York Federal court and such New York court and hereby further waives and agrees
not to plead or claim in any such New York Federal court that any such action,
suit or proceeding brought therein has been brought in an inconvenient forum.

 

(b)           The
Sponsor agrees that a final judgment against it in any action, suit or
proceeding taken in a New York court or New York Federal court in accordance
with clause (a) shall be conclusive and may be enforced in any

law.

 

(c)           To
the extent that the Sponsor has or hereafter may acquire any immunity from

suit or proceeding.  The Sponsor agrees

not impair or affect the validity of such service or any judgment rendered in
any action, suit or proceeding based thereon.

the Sponsor agrees to designate a new agent in the Borough of Manhattan, The
City of New York, on the terms and for the purposes of this Section 7.10.  Nothing herein shall be deemed to limit the

Collateral Agent, the Administrative Agent, the Technical Agent, each Hedge
Bank and each Senior Lender against, and to pay to the Collateral Agent on
demand, in Dollars, any difference between the sum originally due in Dollars
and the amount of Dollars received upon any such conversion and transfer.

Agent, the Administrative Agent, the Technical Agent, any Hedge Bank or any
Senior Lender to exercise and no delay in exercising, and no course of dealing
with respect to, any right, power or privilege under this Agreement or any
other agreement or instrument referred to herein or therein shall operate as a
waiver thereof, nor shall any single or partial exercise of any right, power or
privilege under any such agreement or instrument preclude any other or further
exercise thereof or the exercise of any other right, power or privilege.  The remedies provided herein are cumulative

COMPLETION TEST

 

The “Completion
Test Period” is a period of 100 continuous days during which the
Borrower’s production facilities operate for 90 days or more, ending on or
before the Limit Completion Date, provided that downtime of up to 240 hours
during this period will not require the test to be restarted.  The Completion Test shall be prospective in
nature; the Borrower shall inform the Technical Agent and Independent Engineer at
least 15 days prior to start of the scheduled test.  The Independent Engineer shall be on site for
the commencement and scheduled completion of the Completion Test, with further
visit mid-way through the Completion Test Period as deemed appropriate by the
Independent Engineer and the Technical Agent. 
The Completion Test may be stopped at the discretion of the Borrower and
restarted at any point, with the approval of the Technical Agent and the
Independent Engineer which shall not be unreasonably withheld, prior to the
Limit Completion Date.  Should a stopped
Completion Test be restarted then a new prior notification to the Technical
Agent and Independent Engineer shall be required.

 

Satisfaction of the Completion Test shall require
delivery of the completed certifications in the forms attached as Appendix B-1
through Appendix B-6 to the Completion Agreement.  The Technical Agent shall receive
certificates B-1 through B-4 and B-6 in accordance herewith.  Certificate B-5 shall be delivered directly
to the Administrative Agent.  Upon
receipt and review of certificates B-1 through B-4 and B-6, the Technical Agent
shall deliver the certificates to the Administrative Agent together with a
notification of its conclusions as to whether the relevant documentary
components of the Completion Test have been satisfied.

 

In performing the Completion Test, the Borrower will
conduct the required sampling and assaying in accordance with standard
international mining practices.  All
weight measures referred to in certificates submitted in connection with the
Completion Test will be on a dry basis. 
Measurement of moisture content will be made to adjust the weightometer
and other records to a dry basis.  The
sampling locations and laboratory assay procedures will be verified by the
Independent Engineer.  In cases where a
materiality assessment is required, the Technical Agent, acting on behalf of
the Secured Parties, may determine in concert with the Independent Engineer and
the Borrower appropriate materiality thresholds.

 

During the Completion Test Period, the Borrower shall
operate the Project in accordance with the Operating Plan then in effect and
accepted pursuant to Section 8.14 of the Common Security Agreement.  References below and in the annexed
certificates to the accepted Operating Plan then in effect shall mean at any
time the Initial Operating Plan, or, if there have been any updates or
revisions thereto that have been accepted pursuant to Section 8.14 of the
Common Security Agreement, the latest such update or provision that has been so
accepted.

therewith, except for any work the non-acceptance of which will not materially
and adversely affect the operability of the Project, including safety and
environmental performance;

 

(iii)                               as
of the date of such certificate, the items and quantities of capital spares

Project facilities or arrangements have been made to procure such items to
restore the quantities of capital spares in inventory to the levels specified
in such Operating Plan and these reasonably can be expected to be on hand at or
near the Project facilities within 6 days or such longer periods as may be
dictated by the delivery schedule of ordered long lead-time items which
have been used prior to the date of such certificate;

 

(iv)                              as
of the date of such certificate, no material Project Costs have been incurred
that remain unpaid (unless provided for by satisfactory retentions by the
Borrower and other than Project Costs that are disputed); and

 

(v)                                 as
of the date of such certificate, the accepted Operating Plan then in effect

reserves as outlined in the Initial Operating Plan remaining to be mined after
the scheduled final maturity of the Senior Loan Facilities.

 

(b)                                 Production Test A certificate in the form
of Appendix B-2 signed by the President of the Borrower, verified by the
Independent Engineer, to the effect that during the Completion Test Period:

the Completion Test Period, as described in the accepted Operating Plan then in
effect; and the blast hole to model reconciliation was within 10% of the
forecasted mine block model (the blast hole to model reconciliation calculation
is defined in Annex 2 to Appendix B-2);

 

(iii)                               the
Project has achieved an average zinc equivalent recovery rate for the silver,
zinc and lead contained in the ore milled of not less than ninety per cent
(90%) of the forecast average zinc equivalent recovery rate for the Completion
Test Period, as described in the accepted Operating Plan then in effect (the
recovery 

 

B-2

 

calculation and zinc equivalent calculation is defined
in Annex 3 to Appendix B-2);

 

(iv)                              the
Project has produced zinc metal equivalents contained in the concentrates
produced at a rate not less than ninety five per cent (95%) of the forecast
zinc metal equivalent rate for the production period in which the Completion
Test Period occurs, as described in the accepted Operating Plan then in effect
(the zinc metal equivalent calculation is defined in Annex 3 to Appendix B-2);

FORM OF PHYSICAL
FACILITIES CERTIFICATE

 

I, [Name of
President], President of Minera San Cristóbal S.A. (the “Borrower”),
hereby certify on behalf of the Borrower that, as of the date hereof:

 

(a)                                  a
copy of the Project Description specified in Appendix H to the Common
Security Agreement that incorporates all amendments and changes to such
Appendix H that have been made on or prior to the date hereof is attached
hereto as Annex 1.  As of the date
hereof, all amendments and changes to such Appendix H have been made in
accordance with Section 8.12(c) of the Common Security Agreement;

 

(b)                                 (i)                                     between
the dates of [         ]
and [        ],
[names of employees or agents], [titles], inspected the equipment and
physical facilities of the Project.  We
have considered whether, in our reasonable judgment, the equipment and physical
facilities described in Annex 1 have been installed and have become
operational, in each case at the time of such inspection.  Our work involved inspection of equipment and
facilities and operation thereof, only to the extent necessary to identify such
equipment and facilities and the attributes thereof, if any, referred to in
Annex 1 and to conclude whether such equipment and facilities have become
operational.  Such inspections and
observations were those we, in our reasonable judgment, deemed necessary for
the purposes of delivering this certificate;

 

(ii)                                  we
have noted in the analysis attached hereto as Annex 2 a description of the
equipment which we identified as meeting the requirement of each item listed in
Annex 1, together with a description thereof reasonably sufficient for
purposes of such identification.  The
equipment measures and amounts stated in Annex 2 represent approximate
figures and actual measures and amounts may vary depending upon various
factors, including actual characteristics of available equipment.  Where measures and amounts relating to the actual
equipment installed are approximately those set forth in Annex 1, we have
deemed the installed equipment to be substantially the same as that described
in Annex 1 and have stated the relevant amount or measure in the description
included in Annex 2;

 

(iii)                               based
on and subject to the foregoing, as of the date hereof, equipment and physical
facilities of the Project substantially the same as those described in Annex 2
have been installed and are operational;

 

(c)                                  the
Borrower has delivered (with a copy to the Technical Agent) a copy of the Certificate
of Mechanical Completion (as defined in Section 8.1 of the EPCM Contract)
issued on [insert date] with
respect to [insert portion of the facility to
which the certificate relates] in accordance with Article 8 of
the EPCM Contract.  [insert additional Certificates of Mechanical
Completion as necessary].  As
of the date hereof, Certificates of Mechanical Completion have been delivered
by the Borrower with 

 

B-1-1

 

respect to all portions of the project facilities,
which certify that all conditions of achieving Mechanical Completion as set
forth in the EPCM Contract have been satisfied;

 

(d)                                 as
of the date hereof, the Borrower has delivered notification of its
acceptance of delivery of each of the physical facilities to, and all other
work performed by and equipment delivered by, the contractor under the EPCM
Contract (subject to exception or conditions, if any, none of which would be
reasonably expected to have a material adverse effect on the operation of the
Project, including safety and environmental performance, substantially as
contemplated in the Common Security Agreement and subject to such warranties
and similar provisions as are set out in the EPCM Contract);

 

(e)                                  as
of the date hereof, the items and quantities of capital spares inventory, which
are attached as Annex 3 hereto, are either on hand on or near the facility
of the Project in Bolivia or the Borrower has entered into arrangements to
procure such items to restore the quantities of capital spares in inventory to
the quantities set forth in such Annex 3, and such arrangements have been
made pursuant to an established procurement system that will provide capital
spares in a sound and efficient manner such that such spares and consumables
can be expected to be held in stock at the Project’s facilities or (as the case
may be) will be available from the supplier(s) for dispatch within 6 days (or
such longer periods as may be dictated by the delivery schedule of ordered
long lead-time items which have been used prior to the date hereof) of the
request by the Borrower.  As of the date
hereof, the items and quantities of consumables set forth in Annex 3 are
either on hand at a facility of the Project in Bolivia or have been purchased
by the Borrower;

 

(f)                                    as
of the date hereof, (i) all Project Costs have been paid for by the
Borrower (other than Project Costs which are being disputed by the Borrower in
good faith) or (ii) as to those Project Costs which have not been so paid
for, the Borrower has sufficient funds available to make such payments; and

 

(g)                                 as
of the date hereof, the current Operating Plan (which Operating Plan has been
approved in accordance with Section 8.14 of the Common Security Agreement)
demonstrates a Reserve Tail equal to 80,000,000 tonnes of ore, which amount is
at least 40% of the reserves as outlined in the Initial Operating Plan,
remaining to be mined after the Final Maturity Date.

 

This is the certificate referred to in Section 2.01(a) of
the Completion Agreement, dated as of December 1, 2005 among the Sponsor,
the Technical Agent, the Administrative Agent and the Collateral Agent.  Capitalized terms used herein and in the
annexes hereto, except as otherwise defined herein, shall have the meanings
assigned to them in the Completion Agreement or the Common Security Agreement,

FORM OF PRODUCTION
CERTIFICATE

 

I, [Name of
President], President of Minera San Cristóbal S.A. (the “Borrower”),
hereby certify on behalf of the Borrower that, as of the date hereof:

 

(a)                                  Attached
to this certificate as Annex 1 are copies of operating records, bills of lading
and other data and documentation relating to production by the San Cristobal
Project during the periods referred to in clause (e) below.  Such documentation accurately reflects, in
all material respects, the production of the San Cristobal Project during the
period to which it relates, and evidences compliance with the certifications
set forth in sections (i) through (v) of clause (f) below.

 

(b)                                 All
sampling procedures relevant to the matters covered by this certificate were
conducted by the Borrower in accordance with standard international mining
practices; all assaying was conducted by the Borrower in accordance with
standard international mining practices. 
The sampling locations and laboratory assay procedures have been
verified by the Independent Engineer.

 

(c)                                  The
Independent Engineer was provided with (i) the Borrower’s most recently
approved updated operating plan (accepted as contemplated in Section 8.14
of the Common Security Agreement) that covers the Completion Test Period,
together with the current block model and mine plan included in such operating
plan (collectively, the “Operating Plan”), and (ii) the past 12 months’
operating reports for the Borrower.  The
Operating Plan is in all material respects consistent with, and contemplates
operating and production results not materially divergent from those projected
in, the Initial Operating Plan and Initial Financial Model on which the October 12,
2005 Information Memorandum delivered to the Secured Parties was based (except
for such material changes thereto, if any, as have been previously furnished to
the Secured Parties, reported on by the Independent Engineer, and approved by
the Majority Secured Parties as provided in Section 8.14 of the Common
Security Agreement).

 

(d)                                 The
Operating Plan was provided to the Independent Engineer at least 30 days prior
to the start of the Completion Test Period. 
Notice of the start of the Completion Test Period was given to the
Independent Engineer at least 15 days prior to the start of such period.  The start date of the Completion Test Period
occurred no earlier than October 2007, unless prior to such start date the
Borrower operated the San Cristobal Project at or near full design capacity.
The mine plan included in the Operating Plan was adhered to during the
Completion Test Period.

 

B-2-1

 

(e)                                  For
purposes of this certificate,

 

(i)                                     “Completion
Test Period” is a period of 100 continuous days, ending on or before December 31,
2008 (the “Limit Completion Date”), during which the Borrower’s production
facilities operated for 90 days or more, provided that downtime of up to 240
hours during this period will not require the test to be restarted.

 

(ii)                                  “Operating
Day” is any day other than a day on which the operations of the Project
ceased for more than 12 continuous hours due to force majeure or on which work
of the facilities of the Project was prohibited by applicable law, regulation,
order or labor agreement.

 

(iii)                               “force
majeure” is defined as (a) an act of God, labor dispute and industrial
action of any kind (including, without limitation, a strike, interruption,
slowdown and other similar action on the part of organized labor), a lockout,
act of the public enemy, war (declared or undeclared), civil war, sabotage,
blockade, revolution, riot, insurrection, civil disturbance, terrorism,
epidemic, cyclone, tidal wave, landslide, lightning, earthquake, flood, storm,
fire, adverse weather conditions, expropriation, nationalization, act of
eminent domain, laws, rules, regulations or orders of governmental authority,
acts of other private and public companies, explosion, breakage or accident to
machinery or equipment or power or transmission line or railroad tracks or
equipment or ports or other facility, embargo, inability to obtain or delay in
obtaining equipment, materials, transport, event of political force majeure or
any other event whether similar to the foregoing or not which is not within the
reasonable control of the Borrower, and which has a material adverse effect on
the ability of the Borrower to operate the Project in all material respects in
accordance with the Operating Plan and (b) in the case of any Project
Document or any Material Project Counterparty, an event of force majeure or
uncontrollable force or other similar term as such term is defined or used in
such Project Document.

 

(f)                                    Production
Test. During the Completion Test Period, the Borrower achieved the
following results of operations at the San Cristobal Project:

 

(i)                                     the
Project mined, crushed and milled ore at an average rate of not less than
ninety per cent (90%) of the forecast production rate for the Completion Test
Period, as described in the Operating Plan;

 

(ii)                                  the
Project achieved an average grade for the silver, zinc and lead contained in
the ore mined of not less than ninety percent (90%) of the forecast grade for
the Completion Test Period, as described in the Operating Plan; and the blast
hole to model reconciliation (utilizing the method of calculation described in
Annex 2 to this Certificate) was within ten percent (10%) of the forecasted
mine block model;

 

B-2-2

 

(iii)                               the
Project achieved an average zinc equivalent recovery rate for the silver, zinc
and lead contained in the ore milled of not less than ninety percent (90%) of
the forecast average zinc equivalent recovery rate for the Completion Test
Period, as described in the Operating Plan (the recovery calculation and zinc
equivalent calculation methodology is described in Annex 3 to this
Certificate);

 

(iv)                              the
Project produced zinc metal equivalents contained in the concentrates produced
at a rate not less than ninety five percent (95%) of the forecast zinc metal
equivalent rate for the production period in which the Completion Test Period
occurs, as described in the Operating Plan (the zinc metal equivalent
calculation methodology is described in Annex 3 to this Certificate); and

 

(v)                                 there
was a period of 30 continuous Operating Days within the Completion Test Period
during which the Project mined an average of not less than 40,000 tonnes of ore
per day and, a period of 30 continuous Operating Days within the Completion
Test Period during which the Project milled an average of not less than 40,000
tonnes of ore per day.

 

This is the certificate referred to in Section 2.01(b) of
the Completion Agreement, dated as of December 1, 2005 among the Sponsor,
the Technical Agent, the Administrative Agent and the Collateral Agent.  Capitalized terms used herein and in the

BLAST HOLE TO MODEL
RECONCILIATION

 

The following is an outline of the procedures that
will be detailed by the Borrower for use in the reconciliation of the blast
hole grade and location data base to geologic model.  The procedures will be fully detailed over
the next 12 months (prior to the acceptance of the 2007 Operating Plan) and
provided to the Independent Engineer for inclusion, subject to the Independent
Engineer’s concurrence, in this Annex 2 to Appendix B-2 to the Completion
Agreement.

 

Borrower personnel are developing a suite of
procedures for optimizing blasthole models (short range model) and checking the
reconciliation of these models against the exploration model (long-range
model).  The required input for these procedures are:

 

1.                                       The
blast hole dataset (XYZ collar location, sampled depth, assays.  Optional
items include drilled depth and geology.)

 

2.                                       The
blast hole model (XYZ dump of block centroids, estimated grades and other
relevant geological items). Estimation parameters used in preparing the blast
hole model should also be provided.

 

3.                                       The
exploration model covering the area of the blast hole model (XYZ dump of block
centroids, estimated grades and other relevant geological items.) Estimation
parameters used in preparing the exploration model should also be provided.

 

4.                                       Exploration
composites used in preparation of the exploration model in the area provided
(XYZ location of composite centroid, composite length, composited grades and
other relevant geological items.)

 

5.                                       Diglines
for determining the routing of blast hole model blocks (e.g. waste,ROM, crushed
leach and mill).  These can be provided either as closed polygons or
polylines with left and right codes.

 

6.                                       Monthly
pit progress surveys. These can be provided either as closed polygons or
polylines with left and right codes or tins.

 

7.                                       Client
monthly reconciliation results (through saleable product).

 

At least three months of full production data are
required before blast hole model performance can be reasonably assessed.  Data for any shorter period can only be used
for the purpose of this methodology with the Independent Engineer’s
concurrence.

 

B-2-7

 

The Borrower will have automated procedures for
performing the following analyses:

 

1.                                       Check
of the blast hole model against the blast holes by backmarking.

 

2.                                       Check
of blast hole model estimation parameters by cross validation.  While the Borrower understands the use of
cross validation, at this stage the Borrower will complete further
investigation into whether this analysis will be used as part of the
reconciliation analysis.  If not, then a
more up to date procedure that replaces this analysis will be included.  If this analysis type is not included, a
detailed explanation of the change will be presented and will be subject (for
purposes of this test) to the Independent Engineer’s concurrence.

 

3.                                       Bias
test of blast holes against the composites using the estimation parameters
found by cross validation.  While the
Borrower understands the use of cross validation, at this stage the Borrower
will complete further investigation into whether this analysis will be used as
part of the reconciliation analysis.  If
not, then a more up to date procedure that replaces this analysis will be
included.  If this analysis type is not
included, a detailed explanation of the change will be presented and will be
subject (for purposes of this test) to the Independent Engineer’s concurrence.

 

4.                                       Check
of the blast hole model against long-range model by back marking.

 

5.                                       Check
of monthly client reconciliation by independently calculating long-range and
short range production using the models, dig lines in monthly progress.

METHODOLOGY FOR
CALCULATION OF THE UNIT COST TEST

 

The Unit Cost US$/lb Zn shall be calculated according
to the following procedure:

 

•                                          The
values describing the Borrower’s performance contained in the Initial Financial
Model on sheet,                   
will be updated, with the participation and concurrence of the Independent
Engineer, based on annualized results obtained over the Completion Test Period.

 

•                                          The
performance values to be updated will be based on an audit of mine and mill
production records and G&A records, including operating fixed and variable
consumption items, for the Completion Test Period.  The Independent Engineer will work with
Borrower budgeting personnel at the project site, and with the Sponsor and
