“Tranche B Loan”, and collectively, together with the Tranche A Loans, the “Loans”) to the Borrower on the Borrowing Date in a principal amount equal to its pro rata
portion (in accordance with the respective Tranche B Commitments of all Lenders as of the Borrowing Date) of the Dollar amount of the Tranche B Borrowing set forth in the Notice of Borrowing; provided that the principal amount of Tranche
B Loans made by any Lender shall not exceed the amount of such Lender’s Tranche B Commitment. 
  
 (c) Amounts repaid in respect of Loans may not be reborrowed. All Loans shall be funded in Dollars, as more fully set forth in Section 2.02(a). The
Commitments of the Lenders are several, i.e., the failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder, and no Lender shall be responsible for any other Lender’s
failure to make Loans as and when required hereunder. 
  
 SECTION
2.02. Making the Loans. (a) The borrowing of Loans hereunder (the “Borrowing”) shall be made on notice by the Borrower to the Administrative Agent (which shall give to each Lender
prompt notice thereof) by a written notice of Borrowing (the “Notice of Borrowing”) delivered to the Administrative Agent by facsimile transmission, immediately confirmed by telephone, in substantially the form
of Exhibit A hereto, not later than 10:00a.m. New York City time, on the third Business Day prior to the proposed Borrowing Date. The Notice of Borrowing shall specify therein (i) the proposed date of the Borrowing, which shall be a Business
Day not later than five Business Days after the Effective Date (the “Borrowing Date”), (ii) the proposed aggregate principal amount of the Borrowing, (iii) the aggregate principal amount of the Tranche
A Borrowing and the aggregate principal amount of the Tranche B Borrowing included in such proposed Borrowing, (iv) the duration selected by the Borrower for the Interest Period with respect to any Tranche beginning on such Borrowing Date, and
(v) payment instructions with respect to the proceeds of the Loans. Each Lender shall, before 10:00a.m. (New York City time) on the date of the Borrowing, make available for the account of its Lending Office to the Administrative Agent at the
Administrative Agent’s Account, in same day funds, such Lender’s ratable portion of the Borrowing as determined in accordance with Section 2.01. After the Administrative Agent’s receipt of such funds and upon fulfillment or

  

 20 








 waiver of the applicable conditions set forth in Article III, the Administrative Agent shall disburse such funds in
accordance with the payment instructions specified in the Notice of Borrowing. 
  
 (b) The Notice of Borrowing shall be irrevocable and binding on the Borrower. The Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on
or before the date specified in the Notice of Borrowing for the Borrowing the applicable conditions set forth in Article III, including, without duplication, any loss, cost or expense required to be paid by the Borrower pursuant to Section 2.11
hereof. 
  
 (c) Unless the Administrative Agent shall have
received notice from a Lender prior to the date of the Borrowing that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of the Borrowing, the Administrative Agent may assume that such Lender has made
such portion available to the Administrative Agent on the date of the Borrowing in accordance with subsection (a) of this Section 2.02 and the Administrative Agent may, in reliance upon such assumption, disburse in accordance with
subsection (a) of this Section 2.02 on such date a corresponding amount. If and to the extent that such Lender shall not have so made such ratable portion available to the Administrative Agent, each of such Lender and the Borrower agrees
to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative
Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Loans comprising the Borrowing with respect to the Loans of the Tranche in respect of which such funds were advanced by the Administrative Agent and
(ii) in the case of such Lender, the Federal Funds Rate as in effect for each such day. Any repayment by a Lender to the Administrative Agent in respect of such an amount shall constitute for all purposes hereunder a Loan made under the
relevant Tranche by such Lender on the Borrowing Date. 
  
 (d) The
failure of any Lender to make the Loan to be made by it as part of the Borrowing on the Borrowing Date shall not relieve any other Lender of its obligation, if any, hereunder to make its Loan or Loans on the Borrowing Date, but no Lender shall be
responsible for the failure of any other Lender to make any Loan to be made by such other Lender on the Borrowing Date. 
  
 SECTION 2.03. Fees. (a) The Borrower agrees to pay to the Administrative Agent for the account of the Lenders, on or prior to the Borrowing
Date, the aggregate amount of Up-Front Fees with respect to each Lender hereunder. 
  
 (b) Upon the terms and subject to the conditions set forth in the Fee Letter, the Borrower agrees to pay to the Administrative Agent for the account of one or more Lenders serving as sub-underwriters or Joint Lead
Arrangers as contemplated by the Fee Letter the fees payable to the sub-underwriters as set forth in the Fee Letter, in two equal installments, the first of which shall be paid on or prior to the date hereof, and the second of which shall be paid on
or prior to the Borrowing Date. 
  

 21 








 (c) Upon the terms and subject to the conditions set forth in the Fee Letter, the Borrower agrees to pay,
in two equal installments, the first of which shall be paid on or prior to the date hereof and the second of which shall be paid on or prior to the Borrowing Date, all fees payable to CGMI as set forth in the Fee Letter. 
  
 (d) The Borrower agrees to pay to each Agent for its own account such fees as
the Borrower and such Agent shall from time to time agree in writing. 
  
 (e) The Borrower shall make each payment of fees under this Section 2.03 (collectively, the “Fees”) without deduction in respect of any right of counterclaim or set-off, not later than 10:00 a.m.
(New York City time) on the date when due in U.S. Dollars in same day funds. The Administrative Agent shall promptly thereafter cause to be distributed to each Lender for the account of its Lending Office any such Fees paid to the Administrative
Agent on behalf of such Lender. 
  
 SECTION 2.04. Termination
or Reduction of the Commitments. (a) On the Termination Date, and from time to time thereafter upon each repayment or prepayment of the Loans, each Lender’s Commitment shall be automatically and permanently reduced by an amount equal
to such Lender’s unused Commitment. 
  
 (b) Upon the
occurrence of a Termination Event, each Lender’s Commitment shall be reduced to zero. 
  
 (c) On the Effective Date, the amount of the Lenders’ Tranche A Commitments and Tranche B Commitments shall be reduced, pro rata, to an aggregate amount equal to the Borrowing Amount. 
  
 SECTION 2.05. Payment at Maturity; Amortization and Mandatory
Prepayments. (a) Maturity. Without limitation of Section 2.05 (b), (c), (e) and (f), the Borrower unconditionally promises to pay (i) on the Tranche A Maturity Date, to the Administrative Agent for the account of each
Lender with a Tranche A Loan, the then unpaid principal amount of such Lender’s Tranche A Loan and (ii) on the Tranche B Maturity Date, to the Administrative Agent for the account of each Lender with a Tranche B Loan, the then unpaid
principal amount of such Lender’s Tranche B Loan. 
  
 (b)
Scheduled Amortization and Prepayment from Excess Cash of Tranche A Loans. Subject to adjustment pursuant to Section 2.05(d), the Borrower shall repay the Tranche A Loans as follows: 
  
 (i) On the 6-month Anniversary of the Borrowing Date (the
“First Prepayment Date”), US $40 Million; 
  
 (ii) On the 12-month Anniversary of the Borrowing Date (the “Second Prepayment Date”), US $40
Million plus an amount equal to 75% of Excess Cash at the Borrower, if any, for the period from the First Prepayment Date to the Second Prepayment Date; 
  

 22 








 (iii) On the 18-month Anniversary of the Borrowing Date (the “Third Prepayment

 (iv) On the 24-month Anniversary of the Borrowing Date (the “Fourth Prepayment Date”),
US $50 Million plus an amount equal to 75% of Excess Cash at the Borrower, if any, for the period from the Third Prepayment Date to the Fourth Prepayment Date; 
  
 (v) On the 30-month Anniversary of the Borrowing Date (the “Fifth Prepayment Date”),

Cash Proceeds of (i) the sale or issuance by the Borrower of any of its Equity Interests or (ii) the disposition or sale by the Borrower of any of its property or assets (other than cash and Cash Equivalents in compliance with the
provisions of the Loan Documents and other than any sale or disposition that, individually and in the aggregate, is of de minimis effect). 
  
 (d) Application of Mandatory Prepayments of Tranche A Loans. Each prepayment of principal of Tranche A Loans made (i) in respect of Excess
Cash as provided under Section 2.05(b) or (ii) pursuant to Section 2.05(c), shall be applied to reduce the fixed amortizations of principal stated in Section 2.05(b) in inverse order of maturity. 
  
 (e) Scheduled Amortization of Tranche B Loans. Subject to adjustment
pursuant to Section 2.05(g), the Borrower shall repay the Tranche B Loans on each Anniversary of the Borrowing Date set forth below, in the amount equal to the specified percentage of the Tranche B Loans:

at least 25% of Excess Cash at the Borrower, if any, for the period from the last such principal payment date to such principal payment date, and (ii) on the next Interest Payment Date to occur after consummation thereof and up to an aggregate
maximum amount of US $22 Million, 100% of the Net Cash Proceeds from any sale or issuance by the Borrower of any of its Equity Interests. 
  
 (g) Application of Prepayments of Tranche B Loans. Any prepayment of principal of Tranche B Loans pursuant to Section 2.05(f) shall be
applied, ratably in accordance with the amounts payable thereunder, to reduce each remaining fixed amortization of principal stated in Section 2.05(e). 
  
 (h) Mandatory Prepayment of All Loans Upon Termination Event. The Borrower shall prepay the entire principal amount of all Loans outstanding
hereunder, together with any and all other Obligations of the Borrower owing under the Loan Documents, immediately upon the occurrence of a Termination Event. 
  

(i) Interest and Other Amounts. Each payment of principal under this Section 2.05 shall be made together with interest accrued thereon
through the date of such payment, and all other Obligations then due and payable hereunder, including, without limitation, any break-funding payments due pursuant to Section 2.11 hereof and any amounts payable pursuant to Section 2.12.

  
 SECTION 2.06. Optional Prepayments. (a) The
Borrower shall have the right at any time to prepay the Tranche A Loans and, once the Tranche A Loans have been repaid in full, the Tranche B Loans, in each case, ratably in whole or in part, subject to the provisions of this Section 2.06, in
an aggregate principal amount of not less than US $5 Million and integral multiples of US $1 Million thereof or, if less, the then outstanding aggregate principal amount of the Loans of such Tranche. Each such prepayment of principal shall be made
together with interest accrued thereon through the date of such payment, and all other Obligations then due and payable hereunder, including, without limitation, any break-funding payments due pursuant to Section 2.11 hereof and any amounts
payable pursuant to Section 2.12. Prepayments of principal hereunder shall be applied to the remaining scheduled principal payments in respect of such Loans in the same fashion as mandatory prepayments are applied to such Loans pursuant to
Section 2.05. 
  
 (b) The Borrower shall notify the
Administrative Agent in writing by facsimile transmission, immediately confirmed by telephone and/or e-mail, in accordance with the provisions hereof, which notice shall be not later than 10:00 a.m., New York City time, 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 the Loans of each Tranche or portion thereof to be prepaid. Promptly after it receives any such notice, the Administrative
Agent shall advise the affected Lenders of the contents thereof. 
  

 24 








 SECTION 2.07. Interest. (a) Scheduled Interest. The Borrower shall pay interest on the
unpaid principal amount of each Loan owing to each Lender for each day from the Borrowing Date until the maturity thereof (whether by acceleration or otherwise) at a rate per annum which shall, during each Interest Period applicable thereto, be
equal to LIBOR for such Interest Period plus the relevant Applicable Margin. Interest shall be payable in arrears on the last day of each Interest Period. 
  
 (b) Default Interest. Upon the occurrence and during the continuance of an Event of Default, the Borrower shall pay interest on (i) the unpaid
principal amount of each Loan owing to each Lender, payable in arrears on the dates referred to in paragraph (a) above, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on such Loan
pursuant to paragraph (a) above and (ii) to the fullest extent permitted by law, the amount of any principal, interest, fee or other amount payable hereunder that is not paid when due, from the date such amount shall be due until such
amount shall be paid in full, payable in arrears on the date such amount shall be paid in full and on demand, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid pursuant to paragraph
(a) above. 
  
 SECTION 2.08. Interest Rate
Determination. The Administrative Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Administrative Agent for purposes of Section 2.07(a). 
  
 SECTION 2.09. Increased Costs. (a) If, due to either (i) the
introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), there shall
be any increase in the cost to any Lender of agreeing to make or making, funding or maintaining Loans (excluding for purposes of this Section 2.09 any such increased costs resulting from (x) Taxes or Other Taxes (as to which
Section 2.12 shall govern) and (y) changes in the basis of taxation of overall net income or overall gross income by the United States or by the foreign jurisdiction or state under the laws of which such Lender is organized or has its
Lending Office, or any political subdivision thereof), then the Borrower shall, and from time to time, within five Business Days of the prior written demand (accompanied by a certificate of such Lender specifying the amount so demanded, which
certificate shall be conclusive and binding for all purposes hereunder, absent manifest error) by such Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender additional amounts
sufficient to compensate such Lender for such increased cost; provided, however, that, other than during the Syndication Period or any time that a Default shall have occurred and be continuing, (1) the Borrower shall not be liable to pay
any such additional amounts which relate to a period of time preceding the date which is 90 Business Days prior to the date of such Lender’s written demand; (2) no increased cost shall be compensated to the extent resulting from a failure
by such Lender to comply with any regulatory change or which arises solely as a result of and simultaneously with a change in the Lending Office (other than to the extent such change is required by law or regulations applicable to such Lender or to
the extent such increased costs would have occurred regardless of such change); and (3) no increased cost applicable to any assignees of such Lender shall be compensated in the case of any assignment or transfer by such Lender to such assignee
to the extent that, at the time of such assignment or transfer, such assignee would be entitled to 
  

 25 








 claim compensation and the relevant assignor was not then so entitled. Each Lender agrees, upon reasonable request of the
Borrower that it shall as promptly as it may determine to be commercially reasonable designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, any increased cost hereunder so long as such designation
in the judgment of such Lender will not reduce the amount of any payment receivable by such Lender under this Agreement and is not otherwise disadvantageous to such Lender. 
  
 (b) If any Lender determines that compliance with any law or regulation or any guideline or request from any central bank or
other Governmental Authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender and that the amount of such capital
is increased by or based upon the existence of such Lender’s commitment to lend hereunder and other commitments of this type, then, within five Business Days of the prior written demand (accompanied by a certificate of such Lender specifying
the amount so demanded, which certificate shall be conclusive and binding for all purposes hereunder, absent manifest error) by such Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to the Administrative Agent
for the account of such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender or such corporation in the light of such circumstances, to the extent that such Lender reasonably determines such
increase in capital to be allocable to the existence of such Lender’s commitment to lend hereunder; provided, however, that, other than during the Syndication Period or any time that a Default shall have occurred and be continuing,
(1) the Borrower shall not be liable to pay any such additional amounts which relate to a period of time preceding the date which is 90 Business Days prior to the date of such Lender’s written demand; (2) no such increased cost shall
be compensated to the extent resulting from a failure by such Lender to comply with any regulatory change or which arises solely as a result of and simultaneously with a change in the Lending Office (other than to the extent such change is required
by law or regulations applicable to such Lender or to the extent such increased costs would have occurred regardless of such change); and (3) no such increased cost applicable to any assignees of such Lender shall be compensated in the case of
any assignment or transfer by such Lender to such assignee to the extent that, at the time of such assignment or transfer, such assignee would be entitled to claim compensation and the relevant assignor was not then so entitled. Each Lender agrees,
upon reasonable request of the Borrower that it shall as promptly as it may determine to be commercially reasonable designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, any increase in capital
hereunder so long as such designation in the judgment of such Lender will not reduce the amount of any payment receivable by such Lender under this Agreement and is not otherwise disadvantageous to such Lender. 
  
 SECTION 2.10. Payments and Computations. (a) The Borrower shall
make each payment hereunder, without duplication, without deduction in respect of any right of counterclaim or set-off, not later than 12:00 noon (New York City time) on the day when due in U.S. Dollars to the Administrative Agent at the
Administrative Agent’s Account in same day funds. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or facility fees ratably (other than amounts payable
pursuant to Section 2.09, 2.11, 2.12 or 8.04(c)) to the Lenders for the account of their respective Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Lending
Office, in each case to be applied in 
  

 26 








 accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the
information contained therein in the Register pursuant to Section 8.07(d), from and after the effective date specified in such Assignment and Acceptance, the Administrative Agent shall make all payments hereunder, without duplication, in
respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between
themselves. 
  
 (b) All computations of interest based on LIBOR
shall be made by the Administrative Agent on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or facility fees are payable. Each
determination by the Administrative Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error. 
  
 (c) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding
Business Day, and such extension of time shall in such case be included in the computation of payment of interest or facility fee, as the case may be. 
  
 (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder
that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption,
cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative
Agent, at the Federal Funds Rate. 
  
 (e) The Administrative Agent
shall apply amounts received by it, including without limitation amounts received by the Collateral Agent under the Security Documents and forwarded to the Administrative Agent, first to the payment or reimbursement of amounts owed to the
Agents in such capacity under the Loan Documents, second to the payment or reimbursement of amounts owed to the Lenders under the Loan Documents other than principal and interest on the Loans, third to the payment of accrued and unpaid
interest on the Loans and fourth to the payment of outstanding principal amount of the Loans. 
  
 SECTION 2.11. Break-Funding Payments. If (a) any principal of any Loan is repaid on a day other than the last day of an Interest Period
applicable thereto (including as a result of an Event of Default or pursuant to Section 2.05 or 2.06) or (b) the Borrower fails to borrow, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto, then the
Borrower shall compensate each Lender for its loss, cost and expense attributable to such event, which shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest that would have
accrued on the principal amount of such Loan had such event not occurred, at the rate that would have been 
  

 27 








 applicable to such Loan, for the period from the date of such event to the end of the then current Interest Period
therefor (or, in the case of a failure to borrow or continue, the Interest Period that would have begun on the date of such failure), over (ii) the amount of interest that would accrue on such principal amount for such period at the interest
rate which such Lender would bid were it to bid, at the beginning of such period, for Dollar deposits of a comparable amount and period from other banks in the eurodollar market; provided, however, that no such payments shall be
required in connection with Section 2.05(c). A certificate of any Lender setting forth in reasonable detail the basis for calculating such increased costs owed to such Lender that such Lender is entitled to receive pursuant to this
Section 2.11 shall be delivered to the Borrower and shall be conclusive and binding for all purposes hereunder, absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within ten New York
Business Days after receipt thereof. 
  
 SECTION 2.12.
Taxes. (a) Any and all payments by the Borrower hereunder or any other Loan Document shall be made in accordance with this Article II or the applicable provisions of such other documents, free and clear of and without deduction for any
and all present or future taxes (including, without limitation, value-added taxes and withholding taxes), levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender
and each Agent, taxes imposed on its overall net income, and franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction under the laws of which such Lender or Agent (as the case may be) is organized or any political subdivision
thereof and, in the case of each Lender, taxes imposed on its overall net income, and franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction of such Lender’s Lending Office or any political subdivision thereof other than
taxes on net income or franchise taxes imposed on such Lender solely as a result of entering into this Agreement and receiving payments hereunder (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in
respect of payments hereunder being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or any other Loan Document to
any Lender or any Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.12) such Lender or such Agent
(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 taxation
authority or other authority in accordance with applicable law. 
  
 (b) In addition, the Borrower shall pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from the execution, delivery or registration of, performing under, or
otherwise with respect to, any Loan Document or any other documents to be delivered hereunder or thereunder or from the filing, registration, recording or perfection of any Lien contemplated by this Agreement (hereinafter referred to as
“Other Taxes”). 
  
 (c) The
Borrower shall indemnify each Lender and each Agent for and hold it harmless against the full amount of Taxes or Other Taxes (including, without limitation, taxes of any kind imposed or asserted by any jurisdiction on amounts payable under this
Section 2.12) paid by such Lender or such Agent (as the case may be) and any liability (including penalties, 
  

 28 








 interest and expenses) arising therefrom or with respect thereto, in the currency in which such amounts were paid,
whether or not such Taxes or Other Taxes were correctly or legally imposed or asserted by the applicable jurisdiction. Payment for this indemnification shall be made within 30 days from the date such Lender or such Agent (as the case may be) makes
written demand therefor. 
  
 (d) Within 30 days after the date of
any payment of Taxes pursuant to Section 2.02(a)(iii), the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing such payment to the extent
such a receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Administrative Agent. 
  
 (e) Each Lender shall, upon written request (but only so long as such Lender remains lawfully able to do so), provide each of the Administrative Agent and
the Borrower with two copies of any form, document or other certification, appropriately completed, necessary for the Lender to be exempt from, or entitled to a reduced rate of Tax on payments pursuant to any Loan Document; provided, however,
that a Lender shall not be obligated to complete and deliver any form requiring disclosure of information or statements that it reasonably considers to be confidential or otherwise materially disadvantageous to disclose. Such forms, documents
and certifications shall be delivered by such Lender on or before the date it becomes a party to this Agreement and on or before the date, if any, it changes its Lending Office by designating a different lending office. To the extent that any such
form, document or certification becomes obsolete, such Lender shall upon written request provide either an updated or successor form, document or certification to the Borrower. 
  
 SECTION 2.13. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary,
through the exercise of any right of set-off, or otherwise) on account of the Loans owing to it (other than pursuant to Section 2.09, 2.11, 2.12 or 8.04(c)) in excess of its ratable share of payments on account of the Loans obtained by all the
Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Loans owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however,
that (a) if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the
extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing
Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered; and (b) the provisions of this Section 2.13 shall not be construed to apply to any payment obtained by a Lender
as consideration for the assignment of or sale of a participation in any of its Loans. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.13 may, to the fullest extent permitted by
law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. 
  

 29 








 SECTION 2.14. Use of Proceeds. The proceeds of the Loans shall be available (and the Borrower
agrees that it shall use such proceeds) solely for payment of the Acquisition Price.

or significant arbitration proceeding arising out of or under any collective bargaining agreement is so pending against the Borrower or any of the Relevant Subsidiaries or, to the knowledge of the Borrower or any Relevant Subsidiary, threatened
against the Borrower or any of the Relevant Subsidiaries and (ii) no strike, labor dispute, slowdown or stoppage pending against the Borrower or any of the Relevant Subsidiaries or, to the knowledge of the Borrower or any Relevant Subsidiary,
threatened against the Borrower or any of the Relevant Subsidiaries, which in either clause (i) or (ii) could reasonably be expected to have a Material Adverse Effect. 
  
 (t) The Borrower is subject to civil and commercial law with respect to its obligations under the Loan Documents and the
Acquisition Documents, and the execution, delivery and performance by the Borrower of this Agreement constitute private and commercial acts (jure gestionis acts) rather than public or governmental acts (jure imperii acts). None of the
Borrower or any of the Relevant Subsidiaries nor any of their respective properties has any immunity from jurisdiction of any court or from set-off or any legal process (whether through service or notice, attachment prior to judgment, attachment in
aid of execution, execution or otherwise) under the laws of the United States, Argentina, Venezuela, Mexico, Chile, Luxembourg or the British Virgin Islands, as applicable. 
  
 (u) The Borrower’s obligations under this Agreement constitute direct, secured, unconditional and unsubordinated
obligations of the Borrower and do rank and will rank at least pari passu in priority of payment and in all other respects with all other present and future senior secured, unsubordinated Debt of the Borrower. 
  
 (v) Each of the Loan Documents is in proper legal form under all applicable
laws for the enforcement thereof in accordance with their respective terms against the parties thereto under such laws. To ensure the legality, validity, enforceability or admissibility into evidence of the Loan Documents, it is not necessary that
any of such Loan Documents or any other document be filed or recorded with any applicable Governmental Authority or that any stamp or similar tax be paid on or in respect of this Agreement, or any other such document. Neither the Borrower nor any of
its property has any immunity on the ground of sovereignty or otherwise, from the jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or
otherwise) under any applicable laws in respect of the obligations of the Borrower under the Loan Documents or from the execution or enforcement of any judgment resulting therefrom, and if the Borrower or any of its revenues, assets or properties
should become entitled to any such right of immunity, the Borrower has effectively waived such right pursuant to Section 8.13(d). It is not necessary in 
  

 41 








 order for any Lender to enforce any of its rights or remedies under the Loan Documents or solely by reason of the
execution, delivery and performance by the Borrower of the Loan Documents, that any Lender be licensed or qualified with any Mexican, Luxembourg, Argentine, Chilean or British Virgin Islands Governmental Authority or be entitled to carry on business
in any jurisdiction. 
  
 (w) The Borrower, a non-bank entity
located outside the United States, understands that it is the policy of the Board of Governors of the U.S. Federal Reserve System that extensions of credit by international banking facilities (as defined in Section 204.8(a) of Regulation D) may
be used only to finance the non-U.S. operations of a customer (or its foreign affiliates) located outside the United States as provided in Section 204.8(a)(3)(vi) of Regulation D. Therefore, the Borrower acknowledges that the proceeds of the
Loans by the international banking facility of such Lender will be used solely to finance the Borrower’s operations outside the United States or that of the Borrower’s non-U.S. affiliates. 
  
 (x) Neither the Borrower nor any of its Subsidiaries is an
“investment company”, or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment company”, as such terms are defined in the
Investment Company Act of 1940, as amended. 
  
 (y) No
information, exhibit or report furnished by or on behalf of the Borrower or any of its Subsidiaries to any Lender, any Agent or CGMI in connection with the negotiation of the Loan Documents or pursuant to the terms of any Loan Document contained any
untrue statement of a material fact or omitted to state a material fact necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading, except with respect to forecasts and projections, which
have been prepared in good faith and based on reasonable assumptions in light of all information known, or that should reasonably have been known, to management of the Borrower as of the date of their preparation. 
  
 (z) The provisions in each Loan Document as to (i) the choice of New
York law as the governing law thereof, (ii) the irrevocable appointment of the Process Agent to receive service of process on behalf of the Borrower or any of its Subsidiaries party thereto, (iii) the submission by the Borrower or any of
its Subsidiaries party thereto to the jurisdiction of the New York Courts, and (iv) the manner of effecting service of process as set forth therein, are legal, valid, binding on and enforceable under the laws of the British Virgin Islands,
Luxembourg, Argentina, Chile and Mexico and the jurisdiction of incorporation of each such Subsidiary. 
  
 (aa) As of any date and after giving effect to the application of the proceeds of the Loans hereunder, (a) the fair value of the assets of the
Borrower will exceed its debts, as determined in accordance with Applicable GAAP, and all other liabilities, whether subordinated, contingent or otherwise, (b) the Borrower will be able to pay its Debts and all other liabilities, whether
subordinated, contingent or otherwise, as such Debts and liabilities become due and payable and (c) the Borrower will have sufficient capital to carry on its business.

relating to the Borrower or any of its Subsidiaries to the extent such information was obtained or received in any capacity other than as Agent. 
  
 SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender

this Agreement. 
  
 SECTION 7.05. Indemnification. Each
Lender severally agrees to indemnify each Agent and their agents, officers, directors and employees (to the extent not reimbursed by the Borrowers), ratably according to the respective principal amounts of the Loans made by each of them (or if no
Loans are at the time outstanding, ratably according to the respective amounts of their Commitments), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of
any kind or nature whatsoever that may be imposed on, incurred by, or asserted against such Agent (including reasonable attorney’s fees and expenses) in any way relating to or arising out of the Loan Documents or any action taken or omitted by
such Agent under the Loan Documents including the costs and expenses of defending itself against any claim (collectively, the “Indemnified Costs”), provided that no Lender shall be liable for any portion of the
Indemnified Costs resulting from such Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse each Agent promptly upon demand for its ratable

investigation, litigation or proceeding is brought by any Agent, any Lender or a third party. It is expressly understood and agreed that the Co-Collateral Agent is and shall be third party beneficiary of this Section 7.05 and shall have the
right to enforce the provisions of this Section 7.05 with the same effect as if the Co-Collateral Agent were signatory hereto. Except as expressly stated herein, this Section 7.05 shall be solely for the benefit of the parties to this

Upon any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within 30 days after
the retiring Agent’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which in the case of the Administrative Agent
shall be a commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $250 Million. Upon the acceptance of any appointment as Agent hereunder by a successor
Agent and upon the execution and filing or recording of such financing statements, mortgages, agreements or other instruments or notices, as may be necessary or desirable, or as the Majority Lenders may request, in order to continue the perfection
of the Liens granted or purported to be granted by the Collateral Documents, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations under the Loan Documents. If within 45 days after written notice is given of the retiring Agent’s resignation or removal under this Section 7.06 no successor Agent shall have been
appointed and shall have accepted such appointment, then on such 45th day (a) the retiring Agent’s resignation or removal shall become effective, (b) the retiring Agent shall thereupon be discharged from its duties and obligations
under the Loan Documents and (c) the Majority Lenders shall thereafter perform all duties of the retiring Agent under the Loan Documents until such time, if any, as the Majority Lenders appoint a successor Agent as provided above. After any
retiring Agent’s resignation or removal hereunder as Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under the Loan Documents.

Collateral. (a) Beyond the exercise of reasonable care in the custody thereof, the Collateral Agent shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income
thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Collateral Agent shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in
any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Collateral Agent shall be deemed to have exercised reasonable care in the custody of the Collateral in its
possession if the Collateral is accorded 
  

 60 








 treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any
loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Collateral Agent in good faith. 
  
 (b) The Collateral Agent shall not be responsible for the existence,
genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part
hereunder, except to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Collateral Agent, for the validity or sufficiency of the Collateral or any agreement or assignment contained
therein, for the validity of the title of the Company to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. 
  
 SECTION 7.08. Concerning the Collateral Agent and the Collateral. The
Collateral Agent shall have no duty to act outside of the United States in respect of any Collateral located in the jurisdiction other than the United States (“Foreign Collateral”) but shall at the specific
request of Majority Lenders, appoint a Person or Persons to act on behalf of the Lenders with respect to such Foreign Collateral. Such qualified Person or Persons and the Collateral Agent shall, provided the same are reasonably acceptable to the
Collateral Agent, enter into a collateral assignment pledge agreement, mortgage, enforcing document or other security agreement purporting to relate to the Lien or security interest in such item of Foreign Collateral pursuant to which such Person or
Persons shall exercise the rights and remedies of the Collateral Agent and Lenders in the Collateral for their respective benefit. 
  
 SECTION 7.09. Agents, Experts and Advisers. (a) The Collateral Agent may execute or perform any duties hereunder either directly or by or
through agents, sub-agents, attorneys, custodians or nominees appointed in each case with due care and in good faith, and it shall not be responsible for any willful misconduct or negligence on the part of any agent, attorney, custodian or nominee
so appointed. 
  
 (b) The Collateral Agent may employ or retain
such counsel, accountants, appraisers or other experts or advisers as it may reasonably require for the purpose of determining and discharging its rights and duties hereunder and shall not be responsible for any act or omission on the part of any of
them. 
  
 (c) The Collateral Agent may act and rely and shall be
protected in acting and relying in good faith on the opinion or advice of or information obtained from any counsel, accountant, appraiser or other expert or adviser whether retained or employed by the Borrower or by the Collateral Agent, in relation
to any matter arising in the administration of the trusts hereof. 
  
 (d) An opinion of counsel may be based, insofar as it relates to factual matters of which the Borrower has knowledge, upon the certificate or opinion of or representation by an officer or officers of the Borrower unless such counsel knows
the certificate, opinion or representation upon which such counsel’s opinion may be based is erroneous, or in the exercise of reasonable care should have known the same was erroneous.

Judgment Currency. (a) If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder in U.S. Dollars into another currency, the parties hereto agree, to the fullest extent that they may
effectively do so, that the rate of exchange used shall be that at which, in accordance with normal banking procedures, the Administrative Agent could purchase U.S. Dollars with such other currency in New York City on the New York Business Day
preceding that on which final, non-appealable judgment is given. 
  
 (b) The obligations of the Borrower in respect of any sum due to the Secured Parties hereunder shall, notwithstanding any judgment in a currency other than U.S. Dollars, be discharged only to the extent that on the New York Business Day
following receipt by the Administrative Agent of any sum adjudged to be so due in such other currency, the Administrative Agent may, in accordance with normal, reasonable banking procedures, purchase U.S. Dollars with such other currency. If the
amount of U.S. Dollars so purchased is less than the sum originally due to the Lender, in U.S. Dollars, the Borrower agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to
indemnify the Secured Parties against such loss. 
  
 SECTION 8.15.

Patriot Act. The Borrower shall, and shall cause each of its Subsidiaries to, provide, to the extent commercially reasonable, such information and take such actions as are reasonably requested by any Agent or Lender in order to assist the Agents and
the Lenders in maintaining compliance with the Patriot Act. 
  
 SECTION 8.16. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE AGENTS AND THE LENDERS HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE)
ARISING OUT OF OR RELATING TO THE LOAN DOCUMENTS, THE LOANS OR THE ACTIONS OF ANY AGENT OR ANY LENDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

applicable.

revenues, assets or properties should become entitled to any such right of immunity, Zoompart and I.I.I. have effectively waived such right pursuant to Section 8.13(d). It is not necessary in order for any Lender to enforce any of its rights or
remedies under the Zoompart Succession Documents or the 







 Loan Documents or solely by reason of the execution, delivery and performance by Zoompart and I.I.I. of the Zoompart

the non-U.S. operations of a customer (or its foreign affiliates) located outside the United States as provided in Section 204.8(a)(3)(vi) of Regulation D. Therefore, Zoompart acknowledges that the proceeds of the Loans by the international
banking facility of such Lender will be used solely to finance Zoompart’s operations outside the United States or that of Zoompart’s non-U.S. affiliates. 
  
 (w) Neither Zoompart nor any of its Subsidiaries is an “investment company”, or an “affiliated

I.I.I or any of their respective Subsidiaries to any Lender, any Agent or CGMI in connection with the negotiation of the Zoompart Succession Documents or the Loan Documents or pursuant to the terms of any Zoompart Succession Document or any Loan
Document contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading, except with respect to forecasts

Loans, (a) the fair value of the assets of Zoompart will exceed its debts, as determined in accordance with Applicable GAAP, and all other liabilities, whether subordinated, contingent or otherwise, (b) Zoompart will be able to pay its
Debts and all other liabilities, whether subordinated, contingent or otherwise, as such Debts and liabilities become due and payable and (c) Zoompart will have sufficient capital to carry on its business.

 (u) Zoompart’s obligations under the Credit Agreement constitute direct, secured, unconditional and unsubordinated
obligations of I.I.I, and do rank and will rank at least pari passu in priority of payment and in all other respects with all other present and future senior secured, unsubordinated Debt of Zoompart. 
  
 (v) Each of the Zoompart Succession Documents and the Loan Documents is in
proper legal form under all applicable laws for the enforcement thereof in accordance with their respective terms against the parties thereto under such laws. To ensure the legality, validity, enforceability or admissibility into evidence of the
Zoompart Succession Documents and the Loan Documents, it is not necessary that any of such Zoompart Succession Documents or Loan Documents or any other document be filed or recorded with any applicable Governmental Authority or that any stamp or
similar tax be paid on or in respect of the Zoompart Succession Documents or the Credit Agreement, or any other such document. Neither Zoompart, I.I.I. nor any of their respective property has any immunity on the ground of sovereignty or otherwise,
from the jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) under any applicable laws in respect of the respective obligations
of Zoompart and I.I.I. under the Zoompart Succession Documents or from the execution or enforcement of any judgment resulting therefrom, and if Zoompart, I.I.I. or any of their respective revenues, assets or properties should become entitled to any
such right of immunity, Zoompart and I.I.I. have effectively waived such right pursuant to Section 8.13(d). It is not necessary in order for any Lender to enforce any of its rights or remedies under the Zoompart Succession Documents or the Loan
Documents or solely by reason of the execution, delivery and performance by I.I.I. and Zoompart of the Zoompart Succession Documents or the Loan Documents, that any Lender be licensed or qualified with any Mexican, Luxembourg, Argentine, Chilean or
British Virgin Islands Governmental Authority or be entitled to carry on business in any jurisdiction. 







 (w) Zoompart, a non-bank entity located outside the United States, understands that it is the policy of
the Board of Governors of the U.S. Federal Reserve System that extensions of credit by international banking facilities (as defined in Section 204.8(a) of Regulation D) may be used only to finance the non-U.S. operations of a customer (or its
foreign affiliates) located outside the United States as provided in Section 204.8(a)(3)(vi) of Regulation D. Therefore, Zoompart acknowledges that the proceeds of the Loans by the international banking facility of such Lender will be used
solely to finance Zoompart’s operations outside the United States or that of Zoompart’s non-U.S. affiliates. 
  
 (x) Neither Zoompart nor any of its Subsidiaries is an “investment company”, or an “affiliated person” of, or
“promoter” or “principal underwriter” for, an “investment company”, as such terms are defined in the Investment Company Act of 1940, as amended. 
  
 (y) No information, exhibit or report furnished by or on behalf of Zoompart,
I.I.I. or any of their respective Subsidiaries to any Lender, any Agent or CGMI in connection with the negotiation of the Zoompart Succession Documents or the Loan Documents or pursuant to the terms of any Zoompart Succession Document or any Loan
Document contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading, except with respect to forecasts
and projections, which have been prepared in good faith and based on reasonable assumptions in light of all information known, or that should reasonably have been known, to management of Zoompart as of the date of their preparation. 
  
 (z) The provisions in each Zoompart Succession Documents and each Loan
Document as to (i) the choice of New York law as the governing law thereof, (ii) the irrevocable appointment of the Process Agent to receive service of process on behalf of Zoompart, I.I.I. or any of their respective Subsidiaries party
thereto, (iii) the submission by Zoompart, I.I.I. or any of their respective Subsidiaries party thereto to the jurisdiction of the New York Courts and (iv) the manner of effecting service of process as set forth therein, are legal, valid,
binding on and enforceable under the laws of the British Virgin Islands, Luxembourg, Argentina, Chile and Mexico and the jurisdiction of incorporation of each such Subsidiary. 
  
 (aa) As of any date and after giving effect to each of the Zoompart Succession and the application of the proceeds of the
Loans, (a) the fair value of the assets of Zoompart will exceed its debts, as determined in accordance with Applicable GAAP, and all other liabilities, whether subordinated, contingent or otherwise, (b) Zoompart will be able to pay its
Debts and all other liabilities, whether subordinated, contingent or otherwise, as such Debts and liabilities become due and payable and (c) Zoompart will have sufficient capital to carry on its business. 
  
 (bb) Such other Representations and Warranties as the Majority Lenders shall
require.

 FORM OF OPINION 
  
 The legal opinion to be provided by Cristian J.P.
Mitrani, external general counsel to the Borrower: 
  
 [LETTERHEAD OF THE BORROWER] 
  
 [            ], 2005 
  
 To: Citibank, N.A. and to the banks named in the 
 Credit Agreement (as defined below) 
  
 I.I.I. – INDUSTRIAL INVESTMENTS INC. – CREDIT AGREEMENT  
  
 Ladies and Gentlemen: 
  
 This opinion is furnished to you pursuant to Section 3.02(g)(i) of the Second Amended and Restated Credit Agreement,
dated as of August 16, 2005 (the “Credit Agreement”), among I.I.I. – Industrial Investments Inc. (the “Borrower”), Citibank, N.A. as Administrative Agent (the
“Agent”), Citibank, N.A. as Collateral Agent (the “Collateral Agent”) and the banks named therein (the “Lenders”). Capitalized terms used and not otherwise
defined herein have the meanings assigned to them in the Credit Agreement. 
  
 I have acted as external general counsel to the Borrower in connection with the preparation, execution and delivery of the Credit Agreement. In rendering this opinion, I have reviewed the following documents:

  

	 	a.	a counterpart of the Credit Agreement; 

  

	 	b.	certified copies of the by-laws of the Borrower and all amendments thereto (the “Constitutive Documents”); and 

  

	 	c.	certified copies of the resolution[s] of the board of directors of the Borrower dated [            ], 2005
approving the execution, delivery and performance of the Credit Agreement. 

  
 I have also examined originals or copies, certified or otherwise identified to my satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such
other investigations as I have deemed necessary or appropriate for purposes of this opinion. 
  
 In giving this opinion, I have made the following assumptions without any 
  

 B-1 








 independent investigation or verification of any kind: 
  

	 	(a)	that each of the parties to the Credit Agreement, other than the Borrower, is duly organized and validly existing, has the corporate power and authority to enter into and perform
the Credit Agreement and that the Credit Agreement has been duly authorized, executed and delivered by each such other party; 

  

	 	(b)	the authenticity of all documents submitted to me as originals; 

  

	 	(c)	the conformity to original documents of all documents submitted to me as copies; 

  

	 	(d)	the authenticity of the originals of such copies; 

  

	 	(e)	that the signatures, stamps and seals on all documents submitted to me are genuine; 

  

	 	(f)	the legal capacity of all natural persons; 

  

	 	(g)	the validity under the respective laws of all the documents executed under said laws. In particular, I have assumed that the Credit Agreement constitutes legal, valid and binding
obligations of all parties thereto in accordance with their respective terms under the laws of New York, without any independent investigations thereof; 

  

	 	(h)	the truth and accuracy of the representations and all matters of fact set forth in all relevant documents furnished to me by the Borrower and its respective officers and directors;
and 

  

	 	(i)	that there are no facts or circumstances or matters or documents which may be material to the opinion set out herein which, notwithstanding my reasonable inquiry, have not been
disclosed to me. 

  
 Based upon the foregoing
examination and assumptions and subject to the qualifications set forth below, I am of the opinion that: 
  

	 	1.	The execution and delivery by the Borrower of the Credit Agreement do not, and the performance by the Borrower of its obligations thereunder will not, result in a breach or
violation of any terms or provisions of, or constitute a default under, any of the agreements identified on Schedule A to this opinion. 

  

	 	2.	There exist no restrictions on dividends and cash distributions from the Relevant Subsidiaries to the Borrower, other than restrictions described on Schedule 3.01(e) to the Credit
Agreement. 

  

	 	3.	Subject in each case to the restrictions set forth on Schedule 3.01(e) to the Credit Agreement, the Borrower has, under the respective organizational documents of the Borrower and
its Relevant Subsidiaries and under the laws of their respective jurisdictions, the power to cause the upstreaming of dividends and cash and cash equivalents to the Borrower from its Relevant Subsidiaries as contemplated in the Credit Agreement, and
each of the Relevant Subsidiaries has the legal power to effect such upstreaming to the Borrower. 

  

 B-2 








 The opinions set forth herein are subject to the following qualifications: 
  
 (A) The rights and obligations of the Borrower and the other parties under the Credit
Agreement are subject to the effect of any applicable bankruptcy, liquidation, insolvency, fraudulent transfer, receivership, reorganization, suspension of payments, moratorium or similar laws and regulations now or hereafter in effect relating to
or affecting the enforcement of creditors’ rights generally and to general principles of equity, including without limitation concepts of materiality, reasonableness, good faith and fair dealing. 
  
 (B) This opinion letter is limited to the matters stated herein and no opinions may be
implied as inferred beyond the matters expressly stated herein. 
  
 I am only admitted to practice law in the City of Buenos Aires. 
  
 This opinion is rendered solely for your benefit in connection with the Credit Agreement and for the benefit of any other person to whom you may assign an interest in any Loan in connection with the above matters
(provided that this opinion speaks solely as of the date hereof) and may not be furnished to, quoted or relied upon by any other person or entity (other than each bank, financial institution or institutional lender that becomes a party
to the Credit Agreement from time to time) for any purpose without my prior written consent. 
  
 Very truly yours,

 FORM OF OPINION 
  
 The legal opinion to be provided by Sullivan & Cromwell LLP, New York counsel to
Borrower: 
  
 [    ], 2005 

 
 To the Persons on Attached 
 Schedule I 
  
 Ladies and Gentlemen: 
  
 We have acted as special New York counsel to I.I.I. - Industrial Investments, Inc., a British Virgin Islands international business company (the
“Company”), Siderar S.A.I.C., an Argentine corporation (“Siderar”) and Inversiones Basilea S.A., a Chilean corporation (“Basilea”)7 in connection with the Second Amended and Restated Credit Agreement, dated as of August 16, 2005 (the “Credit Agreement”), among the Company, Citibank, N.A., as Administrative Agent and
as Collateral Agent and the lenders named therein (the “Lenders”), and the Shareholders’ Agreement, dated as of [the date hereof] (the “Shareholders’ Agreement” and, together with the Credit Agreement, the
“Documents”). This opinion is being delivered to you pursuant to Section 3.02 of the Credit Agreement. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Credit Agreement. 
  
 In our capacity as special counsel to the Company, Siderar and Basilea, we
have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. Upon the basis of such examination, it is our opinion that:

  


	7	All references to Basilea shall be deleted in the event that Basilea is not a party to the Shareholders’ Agreement. 

  

 C-1 









	 	1.	The Credit Agreement constitutes a valid and legally binding obligation of the Company enforceable against the Company 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. 
  

	 	2.	The Shareholders’ Agreement constitutes a valid and legally binding obligation of each of Siderar and Basilea enforceable against each of them 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. 

  

	 	3.	No governmental or regulatory consent, authorization, approval or filing is required to be obtained or made by the Company, Siderar or Basilea under the Federal laws of the United
States or the laws of the State of New York for the execution and delivery of the Documents by the Company, Siderar or Basilea, as applicable, or for the borrowing by the Company from the Lenders under the Credit Agreement; provided,
however, that insofar as the borrowing by the Company from the Lenders under the Credit Agreement is concerned, we express no opinion as to bankruptcy, insolvency, reorganization, moratorium and similar laws of general applicability relating
to or affecting creditor’s rights. 

  

	 	4.	The execution and delivery by the Company of the Credit Agreement, and the execution and delivery by Siderar and Basilea of the Shareholders’ Agreement, do not, and the
performance by the Company of its obligations under the Credit Agreement, and the performance by each of Siderar and Basilea of its obligations under the Shareholders’ Agreement, will not, violate any Federal law of the United States or law of
the State of New York applicable to the Company, Siderar or Basilea; provided, however, that, for the purposes of this paragraph (4), we express no opinion with respect to Federal or state securities laws, other antifraud laws,
fraudulent transfer laws, antitrust laws, laws governing the solicitation of deposits and the Employed Retirement Income Security Act of 1974 and related laws; and provided further, that insofar as performance by the Company, Siderar
or Basilea of its obligations under the Documents is concerned, we express no opinion as to bankruptcy, insolvency, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights.


  

	 	5.	The execution and delivery by the Company of the Credit Agreement do not, and the borrowing by the Company pursuant thereto will not, result in a default under or breach of the
agreements listed in Schedule II hereto. 

  

	 	6.	The Company is not and, after giving effect to the borrowing of the Loans and the Company’s payment of the Acquisition price in the manner contemplated by, and subject to the
limitations contained in, the Credit Agreement, would not be on the date hereof, [an “investment company” as defined in the Investment Company Act of 1940] [required to register under, or seek an exemption from, the Investment Company Act
of 1940 in connection with such borrowing and such purchase]. 

  

 C-2 









	 	7.	Assuming that the proceeds of the Loans are used by the Company solely for payment of the Acquisition Price in the manner contemplated by, and subject to the limitations contained
in, the Credit Agreement, the making of the Loans and such use of proceeds will not violate Regulation T, U or X of the Board of Governors of the Federal Reserve System. 

  
 The foregoing opinions are subject to the following comments and qualifications: 
  

	 	A.	The enforceability of provisions of the Credit Agreement purporting to exculpate or exempt a party from, or require indemnification of a party for, its own action or inaction may be
limited to the extent such action or inaction involves gross negligence, recklessness or willful or unlawful conduct. 

  

	 	B.	The enforceability of provisions in the Credit Agreement to the effect that terms may not be amended, waived or otherwise modified except in writing may be limited under certain
circumstances. 

  

	 	C.	We express no opinion with respect to the provisions of Section 8.13 of the Credit Agreement, or any similar provisions of the Shareholders’ Agreement, insofar as it
relates to (i) the subject matter jurisdiction of any United States Federal court to adjudicate any controversy, (ii) the jurisdiction of any courts other than the courts of the State of New York and United States Federal courts, or
(iii) the conclusiveness or enforceability of foreign judgments. 

  

	 	D.	We express no opinion as to the effect of the laws of any jurisdiction in which any Lender is located (other than the State of New York) that limit the interest, fees or other
charges such Lender may impose. 

  

	 	E.	For purposes of our opinion with respect to the performance by each of Siderar and Basilea of its obligations under the Shareholders’ Agreement in paragraph (4) above, we
have assumed compliance by all relevant persons with the provisions of the section of the Shareholders’ Agreement entitled “Compliance with Laws”. 

  
 The foregoing opinions are limited to the Federal laws of the United States and the laws of the State of New York and we are
expressing no opinion as to the effect of the laws of any other jurisdiction. 
  
 With your approval, we have relied as to certain matters on information obtained from public officials, officers of the Company and Siderar and other sources believed by us to be responsible, and we have assumed that
(i) each party to a document has been duly organized and, to the extent applicable, is in good standing under the laws of its jurisdiction of organization, (ii) each a document has been duly authorized, executed and delivered by all
parties thereto, (iii) each party to a document has the power and authority (corporate and other) to execute, deliver and perform such document, (iv) each document constitutes the valid and legally binding obligation of each of the parties
thereto (other than the Company, Siderar and Basilea), enforceable against it in accordance with its terms and (v) the signatures on all documents examined by us are genuine, assumptions which we have not independently verified. 
  

 C-3 








 This opinion is provided to you by us in our capacity as special New York counsel to the Company, Siderar
and Basilea, and may be relied upon by you, each Lender and any successor or permitted assign of an Agent or a Lender under the Credit Agreement; provided, however, that this opinion may not be relied upon by any person for any purpose
other than in connection with the transactions contemplated by the Credit Agreement without, in each instance, our prior written consent 
  
 Very truly yours,

expressed below. 
  
 Based upon the foregoing and subject to the
qualifications specified below, we are of the opinion that: 
  
 (1) Each of Alfa, Hylsamex, Hylsa and Galvak is a sociedad anónima de capital variable, duly organized and validly existing under the laws of Mexico. 
  
 (2) The execution and performance by Hylsamex of the Stock Pledge Agreement and by Alfa and Hylsamex of the Acquisition
Agreement are within their respective corporate powers, have been duly authorized by all respective necessary internal action of, and do not contravene any Mexican Federal law, rule or regulation or the respective estatutos sociales of each
of Hylsamex or Alfa. 
  
 (3) Each of the Stock Pledge Agreement
and the Acquisition Agreement has been duly executed by each of Hylsamex and Alfa, as the case may be, and the Stock Pledge Agreement constitutes the legal, valid and binding obligation of Hylsamex and the Borrower, enforceable against each of
Hylsamex and the Borrower in accordance with its terms. 
  
 (4)
The Stock Pledge Agreement creates a valid and perfected first priority security interest in the Acquired Shares in favor of the Co-Collateral Agent for the benefit of the Lenders. 
  
 (5) The Stock Certificate satisfies the requirements set forth by applicable Mexican Federal law for stock certificates of
sociedades anónimas de capital variable. 
  
 (6) The
execution and performance by the Borrower of the Stock Pledge Agreement and by the Borrower, Siderar and Basilea of the Shareholders’ Agreement does not contravene any Mexican Federal law, rule or regulation. 
  
 (7) No authorization or approval by, and no notice to or filing with, any
Mexican Governmental Authority is required for the execution and performance by the Borrower and Hylsamex of the Stock Pledge Agreement or by Alfa and Hylsamex of the Acquisition Agreement or for the validity or enforceability of the Stock Pledge
Agreement or the Acquisition Agreement, as the case may be, except that (i) in the event of foreclosure under the Stock Pledge Agreement, a notice to, and the no objection of, the Mexican Comisión Federal de Competencia
(the “CFC”) and, if Hylsamex’s pledged securities are then registered with the Registro Nacional de Valores, an approval of the Mexican Comisión Nacional Bancaria y de Valores (the
“CNBV”), may be required, and (ii) for the effectiveness of, and to consummate the transactions contemplated in, the Acquisition Agreement, the no objection of the CFC and the approval of the 
  

 D-3 








 CNBV and the Mexican Comisión Nacional de Inversiones Extranjeras, are required, all of which
approvals specified under (ii) have been obtained and are in full force and effect. 
  
 (8) The choice of the law of the State of New York as the governing law of the Acquisition Agreement, is a valid choice of law. 
  

(9) The submission by each of Alfa and Hylsamex to federal or state courts located in New York County, State of New York, United States of America,
under the Acquisition Agreement is a valid submission to jurisdiction. 
  
 (10) A judgment rendered by a Federal or State court located in New York County, State of New York, United States of America, against either of Siderar or Basilea pursuant to a legal action instituted before any such court in connection
with the Shareholders’ Agreement, would be enforceable against Hylsamex, as issuer of the relevant securities, in the competent courts of Mexico, pursuant to Article 1347A of the Commerce Code, which provides, inter alia, that any
judgment rendered outside Mexico may be enforced by Mexican courts, provided that: 
  
 (a) such judgment is obtained in compliance with the legal requirements of the jurisdiction of the court rendering such judgment and in
compliance with all legal requirements of the Shareholders’ Agreement; 
  
 (b) such judgment is based on an in personam (as opposed to an in rem) action; 
  
 (c) service of process was made personally on Hylsamex; 
  
 (d) such judgment does not contravene Mexican law, public policy of Mexico, international treaties or
agreements binding upon Mexico or generally accepted principles of international law; 
  
 (e) the applicable procedure under the laws of Mexico with respect to the enforcement of foreign judgments (including the issuance of a
letter rogatory by the competent authority of such jurisdiction requesting enforcement of such judgment and the certification of such judgment as authentic by the corresponding authorities of such jurisdiction in accordance with the laws thereof) is
complied with; 
  
 (f) such judgment is final in
the jurisdiction where obtained; 
  
 (g) the
action in respect of which such judgment is rendered is not the subject matter of a lawsuit among the same parties pending before a Mexican court; and 
  
 (h) the courts of such jurisdiction recognize the principles of reciprocity in connection with the enforcement of Mexican judgments in
such jurisdiction. 
  
 (11) A judgment rendered by a Federal or
State court located in New York County, State of New York, United States of America, pursuant to a legal action instituted before any such court in connection with the Acquisition Agreement, would be enforceable against Alfa or 
  

 D-4 








 Hylsamex, as the case may be, in the competent courts of Mexico, pursuant to Article 1347A of the Commerce Code, which
provides, inter alia, that any judgment rendered outside Mexico may be enforced by Mexican courts, provided that: 
  
 (a) such judgment is obtained in compliance with the legal requirements of the jurisdiction of the court rendering such judgment and in
compliance with all legal requirements of the Acquisition Agreement; 
  
 (b) such judgment is strictly for the payment of a certain sum of money, based on an in personam (as opposed to an in rem) action; 
  
 (c) service of process was made personally on the defendant or on the appropriate process agent; 

 
 (d) such judgment does not contravene Mexican law, public
policy of Mexico, international treaties or agreements binding upon Mexico or generally accepted principles of international law; 
  
 (e) the applicable procedure under the laws of Mexico with respect to the enforcement of foreign judgments (including the issuance of a
letter rogatory by the competent authority of such jurisdiction requesting enforcement of such judgment and the certification of such judgment as authentic by the corresponding authorities of such jurisdiction in accordance with the laws thereof) is
complied with; 
  
 (f) such judgment is final in
the jurisdiction where obtained; 
  
 (g) the
action in respect of which such judgment is rendered is not the subject matter of a lawsuit among the same parties pending before a Mexican court; and 
  
 (h) the courts of such jurisdiction recognize the principles of reciprocity in connection with the enforcement of Mexican judgments in
such jurisdiction. 
  
 (12) The Collateral Agent will not, under
current law, be deemed to be a resident in Mexico for tax purposes, by reason solely of the execution, performance or enforcement of the Stock Pledge Agreement. 
  

(13) It is not necessary under the laws of Mexico (i) to enable the Collateral Agent, the Administrative Agent or the Lenders to enforce their
rights under the Stock Pledge Agreement, or (ii) by reason of the execution or performance of the Stock Pledge Agreement, that the Collateral Agent, the Administrative Agent or any Lender be licensed to carry on business in Mexico. 

 
 (14) The payment of dividends or the making of other similar distributions
on its shares by any of Hylsa, Hylsa Puebla or Hylsa Norte as contemplated in the Credit Agreement, would not contravene the provisions of the Inbursa Loan Agreement, to the extent none of Hylsa, Hylsa Puebla or Hylsa Norte are in default of their
respective obligations thereunder or under any other contract or agreement entered into with Inbursa or any other third party that results or may, with the passage of time, result in an event of default under the Inbursa Loan Agreement. 

 

 D-5 








 (15) The payment of dividends or the making of other similar distributions on its shares by Hylsa or any
of its subsidiaries as contemplated in the Credit Agreement, would not contravene the provisions of the Medium Term Notes. 
  
 (16) The estatutos sociales of each of Hylsamex, Hylsa and Galvak do not include any restriction on the payment of dividends by any of Hylsamex,
Hylsa and Galvak, in respect of fully paid and outstanding shares thereof. 
  
     The foregoing opinion is subject to the following qualifications: 
  
 (a) enforcement of the Stock Pledge Agreement, the Acquisition Agreement and the Shareholders’ Agreement may be limited by bankruptcy, concurso
mercantil, quiebra, suspension of payments, insolvency, liquidation, reorganization, moratorium and other similar laws of general application relating to or affecting the rights of creditors generally; 
  
 (b) in any proceedings brought to the courts of Mexico for the enforcement of
the Acquisition Agreement or the Shareholders’ Agreement, a Mexican court would apply Mexican procedural law; 
  
 (c) in the event that proceedings are brought to Mexico, seeking performance of the obligations of the Borrower in Mexico by means of foreclosure of the
Stock Pledge Agreement, pursuant to Ley Monetaria de los Estados Unidos Mexicanos, the obligations of the Borrower may be discharged by payment of any sums due in a currency other than Mexican currency, in Mexican currency at the rate of
exchange prevailing in Mexico on the date when payment is made; 
  
 (d) provisions of the Stock Pledge Agreement granting discretionary authority to the Collateral Agent, the Co-Collateral Agent, the Administrative Agent or the Lenders, cannot be exercised in a manner inconsistent with relevant facts nor
defeat any requirements from a competent authority to produce satisfactory evidence as to the basis of any determination; in addition, under Mexican law, the Borrower will have the right to contest in court any notice or certificate of the
Collateral Agent, the Co-Collateral Agent, the Administrative Agent or any of the Lenders purporting to be conclusive and binding; 
  
 (e) in the event that any legal proceedings are brought to the courts of Mexico, a Spanish translation of the documents required in such proceedings,
prepared by a court-approved translator, would have to be approved by the court after the defendant had been given an opportunity to be heard with respect to the accuracy of the translation, and proceeding would thereafter be based upon the
translated documents; 
  
 (f) with respect to provisions contained
in the Acquisition Agreement and the Shareholders’ Agreement in connection with service of process, it should be noted that service of process by mail does not constitute personal service of process under Mexican law and, since 
  

 D-6 








 such service of process is considered to be a basic procedural requirement, if for purposes of proceedings outside
Mexico, service of process is made by mail, a final judgment based on such process would not be enforced by the courts of Mexico; 
  
 (g) covenants of the Borrower contained in the Stock Pledge Agreement or of the Borrower or Siderar in the Shareholders’ Agreement which purport to
bind any of them on matters reserved by law, or by the estatutos sociales of Hylsamex, to the shareholders or the board of directors of Hylsamex, or which purport to bind shareholders or members of the board of directors of Hylsamex to vote
or refrain from voting, are not enforceable under Mexican law; 
  
 (h) we express no opinion in respect of whether the Stock Pledge Agreement may be enforced by the Collateral Agent or the Co-Collateral Agent without a judicial order to that effect; and 
  
 (i) we express no opinion in respect of the enforceability of the provisions
contained in the “Right of First Refusal” section of the Shareholders’ Agreements, in the context of a judicial foreclosure procedure conducted in Mexico pursuant to the Stock Pledge Agreement. 
  
     We express no opinion as to any laws other than the laws of Mexico.

  
     This opinion is addressed to you solely for your
benefit and it is not to be transferred to anyone else nor is it to be relied upon by anyone else (provided, that it may be relied upon by each permitted successor or assign of an Agent or a Lender under the Credit Agreement) or for any other
purpose or quoted or referred to in any public document or filed with anyone without our express consent. We assume no obligation to update this opinion.

 EXHIBIT E 
  
 FORM OF OPINION 
  
 The legal opinion to be provided by Walkers BVI, British Virgin Islands counsel to Borrower: 
  

			
	 [To be dated as of Borrowing Date]
	 	Our Ref: [    ]

  
 Citibank, N.A. 
 [Address] 
  

Dear Sirs 
  

	Re:	I.I.I. - Industrial Investments Inc. (the “Company”) 

  
 We have been asked to provide this legal opinion to you with regard to the laws of the British Virgin Islands in relation to the Documents (as defined in Schedule 1
hereto) being entered into by the Company in connection with a commercial facility being made available to the Company. 
  
 For the purposes of giving this opinion, we have examined and relied upon the originals, copies or certified translations of the documents listed in Schedule 1.

  
 In giving this opinion we have relied upon the assumptions set out in Schedule
2, which we have not independently verified. 
  
 We are British Virgin Islands
lawyers and express no opinion as to any laws other than the laws of the British Virgin Islands in force and as interpreted at the date of this opinion. We have not, for the purposes of this opinion, made any investigation of the laws, rules or
regulations of any other jurisdiction. Except as explicitly stated herein, we express no opinion in relation to any representation or warranty contained in the Documents nor upon the commercial terms of the transactions contemplated by the
Documents. 
  
 Based upon the foregoing examinations and assumptions and upon such
searches as have been conducted at our request and having regard to legal considerations which we deem relevant, and subject to the qualifications set out in Schedule 3 hereto, we are of the opinion that under the laws of the British Virgin Islands:

  

	1.	The Company is a business company duly re-registered, validly existing and treated as a company limited by shares incorporated under the Business Companies Act, 2004 of the British
Virgin Islands with full power to execute and deliver the Documents and to perform the provisions of the Documents to be performed on its part. Based on the Registered Agent’s Certificate referred to in Schedule 1, Certificate of Good Standing
referred to in Schedule 1 and the search of the Register of Corporate Affairs referred to below, the Company is in good standing under the laws of the British Virgin Islands. 

  

 E-1 









	2.	The Company has full corporate power and authority to execute and deliver the Documents to which it is a party and to perform its obligations under the Documents.


  

	3.	The Documents to which the Company is a party have been duly authorised and executed by the Company and constitute the legal, valid and binding obligations of the Company
enforceable in accordance with their respective terms. 

  

	4.	The execution, delivery and performance of the Documents to which the Company is a party, the consummation of the transactions contemplated thereby and the compliance by the Company
with the terms and provisions thereof do not: 

  

	 	(a)	contravene any law or regulation of the British Virgin Islands applicable to the Company; or 

  

	 	(b)	contravene the Memorandum and Articles of Association of the Company. 

  

	5.	Neither the execution, delivery or performance of the Documents to which the Company is a party nor the consummation or performance of the transactions contemplated thereby by the
Company, requires the consent or approval of, the giving of notice to, or the registration with, or the taking of any other action in respect of, any British Virgin Islands governmental or judicial authority or agency. 

  

	6.	The law chosen in each of the Documents to which the Company is a party to govern its interpretation would be upheld as a valid choice of law in any action on that document in the
courts of the British Virgin Islands. 

  

	7.	There are no stamp duties, income taxes, withholdings, deductions, levies, registration taxes, or other duties or similar taxes or charges payable in connection with the enforcement
or admissibility in evidence of the Documents or on any payment to be made by the Company or any other person pursuant to the Documents. 

  

	8.	None of the parties to the Documents (other than the Company) is or will be deemed to be resident, domiciled or carrying on business in the British Virgin Islands by reason only of
the execution, delivery, performance or enforcement of the Documents to which any of them is party. 

  

	9.	The Company has executed an effective submission to the jurisdictions specified in the Documents. 

  

	10.	A judgment obtained in a foreign court, including the Courts of the State of New York, will be recognised and enforced in the courts of the British Virgin Islands at common law
without any re-examination of the merits, by an action commenced on the foreign judgment debt in the courts of the British Virgin Islands, where the judgment is final and not subject to a stay of execution. 

  

 E-2 








 In each case, the British Virgin Islands courts would enforce the relevant judgment, in the manner set
out above, provided that: 
  

	 	(i)	such court had jurisdiction in the matter and the Company was duly served with process; 

  

	 	(ii)	the judgment given by such court was not in respect of penalties, taxes, fines or similar fiscal or revenue obligations of the Company; 

  

	 	(iii)	in obtaining judgment there was no fraud on the part of the person in whose favour judgment was given or on the part of the court; 

  

	 	(iv)	recognition or enforcement of the judgment in the British Virgin Islands would not be contrary to the rules of public policy of the BVI courts; and 

  

	 	(v)	the proceedings pursuant to which judgment was obtained were not contrary to natural justice. 

  

	11.	The Company is subject to civil and commercial law with respect to its obligations under the Documents and neither the Company nor any of its assets is entitled to immunity from
suit or enforcement of a judgment on the grounds of sovereignty or otherwise in the courts of the British Virgin Islands in proceedings against the Company in respect of any obligations under the Documents, which obligations constitute private and
commercial acts rather than governmental or public acts. 

  

	12.	Based solely on a search of the public records in respect of the Company maintained at the offices of the Registrar of Corporate Affairs on
[            ]8 at [    :00
am/pm] (which would not reveal details of matters which have not been lodged for registration or have been lodged for registration but not actually registered at the time of our search), a search of the Cause Book of the High Court of the British
Virgin Islands conducted on [            ] at [    :00 am/pm] (which would not reveal details of proceedings which have been filed but not actually entered in the
Cause Book at the time of our search) and the information contained within the Registered Agent’s Certificate referred to in Schedule 1, there are no entries in the Register of Registered Charges maintained for the Company, no actions, suits or
proceedings pending against the Company before any court in the British Virgin Islands and no steps have been, or are being, taken in the British Virgin Islands for the appointment of a receiver or liquidator to, or for the winding-up, dissolution,
reconstruction or reorganisation of the Company. 

  

	13.	A court of the British Virgin Islands has jurisdiction to give judgment in the currency of the relevant obligation. 

  

	14.	The obligations of the Company under the Documents constitute primary, direct, unconditional and general obligations and rank, in priority, at least pari passu with the
unsecured loans, debts, guarantees or other unsecured obligations in respect of borrowed monies of the Company. 

  


	8	This should be dated as of the date the legal opinion is being delivered. 

  

 E-3 









	15.	The Company has all authorizations to create and file[, and has created and filed] with its corporate records on the Closing Date (as defined in the Credit Agreement) a register of
charges in respect of the security interests created pursuant to the Collateral Documents (as defined in the Credit Agreement) in the Collateral (as defined in the Credit Agreement) and the Company has all authorisations to apply [, and has
applied] 9 to the Registrar of Corporate Affairs to register the security interests created pursuant to the
Collateral Documents in the Collateral in the Register of Registered Charges maintained by the Registrar of Corporate Affairs with respect to the Company. Assuming no registration of a security interest against the Company between the date and time
of our searches set out in paragraph 12 above and the registration of the security interests described above in this paragraph, upon the registration of the security interests described above in this paragraph and the issue of a certificate of
registration by the Registrar of Corporate Affairs, the secured interests created in the Collateral will have a first priority security interest in the Collateral and will rank in priority to all secured interests over the Collateral.


  

	16.	It is not necessary in order to ensure the legality, validity, enforceability or admissibility in evidence of proceedings of the obligations of the Company or the rights of any
creditor under the Documents that they or any one of them or any other document be notarised, filed, registered or recorded in the British Virgin Islands. Notwithstanding the foregoing, the Company is required to maintain a register of charges at
its registered office and enter the details of any security interest on that register and failure to do so may result in a fine. In order to ensure the preservation of the priority of any security interests created by the Documents, registration of
the relevant security interest in the Register of Registered Charges maintained by the Registrar of Corporate Affairs, as described above, is required. 

  

	17.	There are no foreign exchange controls or foreign exchange regulations under the currently applicable laws of the British Virgin Islands. 

  

	18.	The Company has all necessary authorizations to accept the Capital Contributions (as defined in the Credit Agreement) to be made by members of the Company, or third party investors,
to the Company pursuant to the Credit Agreement, and if made in accordance with the terms of the Credit Agreement, shall be valid, binding and enforceable by the Company in accordance with the terms of the Credit Agreement in the British Virgin
Islands. Where such Capital Contributions are made in the form of subordinated debt, the subordination provisions of such debt as set forth in the Subordinated Loan Agreement are enforceable in accordance with the terms of the Subordinated Loan
Agreement in the courts of the British Virgin Islands. 

  
 This
opinion is limited to the matters referred to herein and shall not be construed as extending to any other matter or document not referred to herein. This opinion is given solely for your benefit 
  


	9	Confirm with Registrar of Corporate Affairs 

  

 E-4 








 and the benefit of your legal advisers acting in that capacity in relation to this transaction and may not be relied upon
by any other person (provided, that it may be relied upon by each permitted sucesor or assign of an Agent or a Lender under the Credit Agreement) without our prior written consent. 
  
 This opinion shall be construed in accordance with the laws of the British Virgin Islands. 
  
 Yours faithfully 
  
  
 WALKERS

 SCHEDULE 2 
  

Assumptions 
  
 The opinions hereinbefore given are based upon the following assumptions: 
  

	1.	There are no provisions of the laws of any jurisdiction outside the British Virgin Islands which would be contravened by the execution or delivery of the Documents and that, in so
far as any obligation expressed to be incurred under the Documents is to be performed in or is otherwise subject to the laws of any jurisdiction outside the British Virgin Islands, its performance will not be illegal by virtue of the laws of that
jurisdiction. 

  

	2.	The Documents are within the capacity and powers of and have been or will be duly authorised, executed and delivered by each of the parties thereto (other than the Company) and
constitute or will, when executed and delivered, constitute the legal, valid and binding obligations of each of the parties thereto enforceable in accordance with their terms as a matter of the laws of all relevant jurisdictions (other than the
British Virgin Islands). 

  

	3.	The choice of the laws of the jurisdiction selected to govern the Documents has been made in good faith and will be regarded as a valid and binding selection which will be upheld in
the courts of that jurisdiction and all other relevant jurisdictions (other than the British Virgin Islands). 

  

	4.	All authorisations, approvals, consents, licences and exemptions required by, and all filings and other requirements of each of the parties to the Documents outside the British
Virgin Islands to ensure the legality, validity and enforceability of the Documents have been or will be duly obtained, made or fulfilled and are and will remain in full force and effect and that any conditions to which they are subject have been
satisfied. 

  

	5.	All conditions precedent, if any, contained in the Documents, other than the delivery of a favourable opinion of BVI counsel to the Borrower, have been or will be satisfied or
waived. 

  

	6.	The Company on the date of execution of the Documents was not unable to pay its debts as they became due, had not failed to comply with any statutory demand for payment, and does
not have any execution or other process issued on judgement, decree or order of a Virgin Islands court returned wholly or partially unsatisfied (“Insolvency Events”), and the transactions contemplated by the Documents will not cause
an Insolvency Event. 

  

	7.	The originals of all documents examined in connection with this opinion are authentic, all seals thereon and the signatures and initials thereon of any person authorised to execute
the Documents are genuine, all such documents purporting to be sealed have been so sealed, all copies are complete and conform to their originals or are a true translation of

 E-II-2 








 SCHEDULE 3 
  

Qualifications 
  
 The opinions hereinbefore given are subject to the following qualifications: 
  

	1.	The term “enforceable” and its cognates as used in this opinion means that the obligations assumed by the Company under the Documents are of a type which the courts of the
British Virgin Islands enforce; this does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular: 

  

	 	(a)	enforcement of obligations and the priority of obligations may be limited by bankruptcy, insolvency, liquidation, reorganisation, readjustment of debts, disclaimer of onerous
property in liquidation or moratorium and other laws of general application relating to or affecting the rights of creditors or by prescription or lapse of time; 

  

	 	(b)	enforcement may be limited by general principles of equity and, in particular, the availability of certain equitable remedies such as injunction or specific performance of an
obligation may be limited where the court considers damages to be an adequate remedy; 

  

	 	(c)	claims may become barred under statutes of limitation or may be or become subject to defences of set-off, counterclaim, estoppel and similar defences; 

  

	 	(d)	where obligations are to be performed in a jurisdiction outside the British Virgin Islands, they may not be enforceable in the British Virgin Islands to the extent that performance
would be illegal under the laws of or contrary to the public policy of, that jurisdiction; 

  

	 	(e)	in liquidation proceedings in respect of the Company before a court of the British Virgin Islands it is likely that the court will require all debts of the Company to be proved in a
common currency, which is likely to be the Company’s functional currency; 

  

	 	(f)	to the extent that any provision of the Documents is adjudicated to be penal in nature, it will not be enforceable in the courts of the British Virgin Islands; in particular, the
enforceability of any provision of the Documents which imposes additional obligations in the event of any breach or default, or of payment or prepayment being made other than on an agreed date may be limited to the extent that it is subsequently
adjudicated to be penal in nature and not an attempt to make a reasonable pre-estimate of loss; 

  

 E-III-1 









	 	(g)	to the extent that the performance of any obligation arising under the Documents would be fraudulent or contrary to public policy, it will not be enforceable in the courts of the
British Virgin Islands; 

  

	 	(h)	a British Virgin Islands court will not necessarily award costs in litigation in accordance with contractual provisions in this regard; and 

  

	 	(i)	the effectiveness of terms in the Documents excusing any party from a liability or duty otherwise owed or indemnifying that party from the consequences of incurring such liability
or breaching such duty shall be construed in accordance with, and shall be limited by, applicable law, including generally applicable rules and principles of common law and equity. 

  

	2.	A certificate, determination, calculation or designation of any party to the Documents as to any matter provided therein might be held by a British Virgin Islands court not to be
conclusive, final and binding, notwithstanding any provision to that effect therein contained, if, for example, it could be shown to have an unreasonable, arbitrary or improper basis or in the event of manifest error. 

  

	3.	If any provision of the Documents is held to be illegal, invalid or unenforceable, severance of such provision from the remaining provisions will be subject to the discretion of the
British Virgin Islands courts notwithstanding any express provisions in this regard. 

  

	4.	To maintain the Company in good standing under the laws of the British Virgin Islands, annual filing fees must be paid to the Registrar of Corporate Affairs.


  

	5.	We express no opinion upon the effectiveness of any clause of the Documents providing that the terms thereof may only be amended in writing. 

  

	6.	Notwithstanding any purported date of execution in any of the Documents, the rights and obligations therein contained take effect only on the actual execution and delivery thereof
but the Documents may provide that they have retrospective effect as between the parties thereto alone. 

  

	7.	All powers of attorney granted by the Company in the Documents which by their terms are expressed to be irrevocable are valid and irrevocable only if given to secure a proprietary
interest of the donee of the power or the performance of an obligation owed to the donee. Where a power of attorney granted by the Company is expressed to be irrevocable and is given to secure (a) a proprietary interest of the donee of the
power or (b) the performance of an obligation owed to the donee, then, so long as the donee has that interest or the obligation remains undischarged, the power shall not be revoked (i) by the donor without the consent of the donee or
(ii) by the death, incapacity or bankruptcy of the donor, or if the donor is a body corporate, by its winding-up or dissolution. 

  

	8.	We render no opinion as to the specific enforcement as against the Company of covenants granted by the Company to do or to omit to do any action or other matter which is reserved by

 FORM OF OPINION 
  
 The legal opinion to be provided by Bruchou, Fernández Madero, Lombardi & Mitrani, Argentine counsel to Borrower: 
  
 [LETTERHEAD OF BFML&M] 
  
 [                    ], 2005 
  
 To: Citibank, N.A. and to the banks named in the 
 Credit Agreement (as defined below) 
  
 I.I.I. – INDUSTRIAL INVESTMENTS INC. – CREDIT AGREEMENT 
  
 Ladies and Gentlemen: 
  
 This opinion is furnished to you pursuant to Section 3.02(g)(v) of the Second Amended and Restated Credit Agreement, dated as of August 16, 2005
(the “Credit Agreement”), among I.I.I. – Industrial Investments Inc. (the “Borrower”), Citibank, N.A. as Administrative Agent (the
“Agent”), Citibank, N.A. as Collateral Agent (the “Collateral Agent”) and the banks named therein (the
“Lenders”). Capitalized terms used and not otherwise defined herein have the meanings assigned to them in the Credit Agreement. 
  
 We have acted as Argentine external legal counsel to Siderar (as defined below) in connection with the preparation,
execution and delivery of the Shareholders’ Agreement (as defined below). In rendering this opinion, we have reviewed the following documents: 
  

	 	a.	a counterpart of the Shareholders’ Agreement, dated as of [            ], among Siderar S.A.I.C.
(“Siderar”), Inversiones Basilea S.A. (“Basilea”)13 the Borrower, the Collateral Agent and the Agent (the
“Shareholders’ Agreement”); 

  

	 	b.	certified copies of the by-laws of Siderar and all amendments thereto together with the relevant evidence of registration thereof with the Public Registry of Commerce of the City of
Buenos Aires (Inspección General de Justicia) (the “Constitutive Documents”); and 

  

	 	c.	certified copies of the resolution[s] of the board of directors of Siderar, dated [            ], 2005,
authorizing the execution, delivery and performance of the Shareholders’ Agreement. 

  


	13	All references to Basilea shall be deleted in the event that Basilea is not a party to the Shareholders’ Agreement. 

  

 F-1 








 We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such
documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations as we have deemed necessary or appropriate for purposes of this opinion. 
  
 In giving this opinion, we have made the following assumptions without any
independent investigation or verification of any kind: 
  

	 	(a)	that each of the parties to the Shareholders’ Agreement, other than Siderar, is duly organized and validly existing, has the corporate power and authority to enter into and
perform the Shareholders’ Agreement and that the Shareholders’ Agreement has been duly authorized, executed and delivered by each such other party; 

  

	 	(b)	the authenticity of all documents submitted to us as originals; 

  

	 	(c)	the conformity to original documents of all documents submitted to us as copies; 

  

	 	(d)	the authenticity of the originals of such copies; 

  

	 	(e)	that the signatures, stamps and seals on all documents submitted to us are genuine; 

  

	 	(f)	the legal capacity of all natural persons; 

  

	 	(g)	the validity under the respective laws of all the documents executed under said laws, other than Argentine law. In particular, we have assumed that the Shareholders’ Agreement
constitutes legal, valid and binding obligations of all parties thereto in accordance with its respective terms under the laws of New York, Mexico and Chile, without any independent investigations thereof; 

  

	 	(h)	the truth and accuracy of the representations and all matters of fact set forth in all relevant documents furnished to us by Siderar and its respective officers and directors; and


  

	 	(i)	that there are no facts or circumstances or matters or documents which may be material to the opinions set out herein which, notwithstanding our reasonable inquiry, have not been
disclosed to us. 

  
 Based upon the foregoing
examination and assumptions and subject to the qualifications set forth below, we are of the opinion that: 
  

	 	1.	Siderar is a sociedad anónima industrial y comercial duly organized and validly existing under the laws of Argentina and has the corporate power and authority to own
its property and assets and to transact the business in which it is engaged. 

  

	 	2.	Siderar has full corporate power and authority to execute, deliver and perform its obligations under the Shareholders’ Agreement, and Siderar has taken all necessary corporate
action to authorize its entry into the Shareholders’ Agreement and the exercise of its rights and the performance of its obligations under the Shareholders’ Agreement. 

  

	 	3.	Siderar has full corporate power and authority to acquire shares of 

  

 F-2 









	 	  	Hylsamex in connection with the Acquisition (the “Hylsamex Shares”), and Siderar has taken all necessary corporate action to authorize
its acquisition of the Hylsamex Shares. 

  

	 	4.	The Shareholders’ Agreement has been duly executed and delivered by Siderar and, assuming that it constitutes legal, valid, binding and enforceable obligations of Siderar under
the laws of the State of New York and Mexico, the Shareholders’ Agreement will constitute legal, valid and binding obligations of Siderar under the laws of Argentina, enforceable against Siderar in accordance with its terms subject to the
effect of any applicable bankruptcy, liquidation, insolvency, fraudulent transfer, receivership, reorganization, suspension of payments, moratorium or similar laws and regulations now or hereafter in effect relating to or affecting the enforcement
of creditors’ rights generally and to general principles of equity, including without limitation concepts of materiality, reasonableness, good faith and fair dealing (collectively, the “Enforceability
Exceptions”). 

  

	 	5.	The execution, delivery and performance of the Shareholders’ Agreement, the consummation of the transactions contemplated thereby, the compliance by Siderar with the terms and
provisions thereof and the acquisition by Siderar of the Hylsamex Shares do not and will not: (a) contravene any law, statute, rule, regulation or public policy of Argentina applicable to Siderar; or (b) contravene the organizing documents
(including estatutos sociales) of Siderar, or (c) contravene any agreement to which Siderar is a party or any court ruling or arbitral decision applicable to Siderar. 

  

	 	6.	None of the execution, delivery or performance of the Shareholders’ Agreement, the consummation or performance of the transactions contemplated thereby or the acquisition of
the Hylsamex Shares by Siderar requires the consent or approval of, the giving of notice to, or the registration with, or the taking of any other action in respect of, any Argentine Governmental Authority, except that (a) the authorization of
the Central Bank of Argentina shall be required to allow Siderar to exchange Argentine Pesos for Dollars through the local free foreign exchange market (Mercado Unico y Libre de Cambios) in order to transfer funds from Argentina to pay the
purchase price of the Hylsamex Shares that are not purchased by the Borrower if such amount is in excess of Dollars two million per month, and (b) disclosure notice will be required to be given by Siderar to the Argentine Comisión
Nacional de Valores and the Buenos Aires Stock Exchange in accordance with the relevant Argentine securities laws and regulations. 

  

	 	7.	The choice of New York law to govern the Shareholders’ Agreement is, under the laws of Argentina, a valid and effective choice of law, and an 

  

 F-3 








 Argentine court would give effect to such choice of law in any action, suit or proceeding arising out
of, or otherwise relating to, the Shareholders’ Agreement; provided that (i) they are not found by an Argentine court to be contrary to the public policy (orden público) of Argentina (and we opine that it is not contrary to
such public policy), and (ii) the applicable provisions of the laws of the State of New York must be entered into evidence in accordance with Argentine law. 
  

	 	8.	No registration charges or taxes, including, without limitation, stamp, transaction, registration or similar taxes, are required to be paid to ensure the legality, validity, or
enforceability of the Shareholders’ Agreement except, in the case of a court proceeding in Argentina, for a court tax (tasa de justicia) at the rate set forth by the local procedure codes in effect in each of the provincial jurisdictions
involved (which tax as of the date hereof is levied at a rate equal to 3.0% of the amount claimed in the courts located in the City of Buenos Aires). 

  

	 	9.	None of the parties to the Shareholders’ Agreement (other than Siderar) is or will be deemed to be resident, domiciled or carrying on business in Argentina by reason only of
the execution, delivery, performance or enforcement of the Shareholders’ Agreement, nor is it necessary for the execution, performance by it and enforcement of the Shareholders’ Agreement that any of such other parties be authorized or
qualified to carry on business in Argentina. 

  

	 	10.	The submission by Siderar in the Shareholders’ Agreement to the jurisdiction of the federal and state courts located in the City of New York, New York, assuming such service is
valid under New York law, are valid and effective under the laws of Argentina and are irrevocably binding on Siderar; provided that, with respect to service of process (including service of process upon any process agent outside Argentina), the
provisions of Article 517(2) of the National Code of Civil and Commercial Procedures of Argentina (the “CPCC”) are complied with, which require that the defendant against whom enforcement of the judgment
is sought was personally served with the summons and, in accordance with due process of law, was given an opportunity to defend against the foreign actions. Service of process in respect of any claim against Siderar under the Shareholders’
Agreement will constitute personal service of process on Siderar under such agreement for purposes of Article 517 of the CPCC. 

  

	 	11.	Any judgment against Siderar obtained in a foreign court (including a New York court) arising out of or in relation to the obligations of Siderar under the Shareholders’
Agreement would be recognized and enforced by the courts of Argentina without reconsideration on the merits provided that the requirements of Articles 517 through 519 of the CPCC, are complied with (including the obtaining of an exequatur).


  

 F-4 









	 	12.	Siderar is subject to civil and commercial law with respect to its obligations under the Shareholders’ Agreement, and the execution, delivery and performance by Siderar of the
Shareholders’ Agreement constitute private and commercial acts. Neither Siderar nor any of its Argentine properties, revenues or assets has any immunity from the jurisdiction of any court or from set-off or any legal process (whether through
service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) under the laws of Argentina. 

  

	 	13.	There are no actions, suits or proceedings pending against Siderar before any court in Argentina and no steps have been, or are being taken in Argentina for the appointment of a
receiver or liquidator to, or for the winding-up, liquidation, dissolution, reconstruction or reorganization of Siderar. 

  

	 	14.	A court of Argentina has jurisdiction to give judgment in the currency of the relevant obligation. The ability of any foreign Person to remit out of Argentina the proceeds of any
judgment award in non-Argentine currency issued by a court in Argentina is not subject to the prior authorization of the Central Bank of Argentina to the extent such Person complies with the duties set forth in Communication “A” 4129 of
the Central Bank of Argentina, as supplemented and amended. 

  

	 	15.	The Shareholders’ Agreement is in proper legal form under the laws of Argentina for the enforcement thereof in accordance with its terms against Siderar (assuming, in the case
of the documents governed by the laws of the State of New York, their validity and enforceability in accordance with their terms under such laws) (provided that a certified translation by a sworn public translator into the Spanish language of any
document in a language other than Spanish is required to bring an action thereon in the courts of Argentina); and, to ensure the legality, validity, enforceability and admissibility in evidence of the Shareholders’ Agreement in Argentina, it is
not necessary that the Shareholders’ Agreement be filed or recorded with any court or other authority in Argentina; provided that pursuant to Argentine Law No. 24,573, as amended, and its regulatory decree No. 91/98, as amended and
supplemented, certain mediation procedures must be exhausted prior to the initiation of lawsuits in Argentina, with the exception, among others, of bankruptcy and executory proceedings, which executory proceedings include the enforcement of foreign
judgments and of instruments that qualify as título ejecutivo under Argentine law, in which case mediation procedures remain optional for the plaintiff. 

  

 F-5 








 The opinions set forth herein are subject to the following qualifications: 
  
 (A) Enforcement of foreign judgments against Siderar in Argentina is subject to compliance
with the requirements of Articles 517 through 519 of the CPCC, namely that: 
  

	 	(a)	the judgment, which must be final in the jurisdiction where rendered, was issued by a court competent in accordance with the Argentine laws regarding conflicts of laws and
jurisdiction and other principles and rules of international law, and results from a personal action, or an in rem action with respect to personal property, as opposed to real property, which was transferred to Argentine territory during or
after the prosecution of the foreign action; 

  

	 	(b)	the defendant against whom enforcement of the judgment is sought was personally served with the summons and, in accordance with due process of law, was given an opportunity to
defend against the foreign action; 

  

	 	(c)	the judgment must be valid in the jurisdiction where rendered and its authenticity must be established in accordance with the requirements of Argentine law;


  

	 	(d)	the judgment does not violate the principles of public policy of Argentine law (including Argentine Law No. 24,871); 

  

	 	(e)	the judgment is not contrary to a prior or simultaneous judgment of an Argentine court; and 

  

	 	(f)	that in respect of any document in a language other than Spanish (including, without limitation, the foreign judgment and other documents related thereto), a duly legalized
translation by a sworn public translator into the Spanish language is submitted to the relevant court. 

  
 (B) Enforcement by a foreign party having neither domicile nor assets in Argentina may be subject to posting a guarantee for payment of costs payable in case the action
is rejected or dismissed (the defense giving rise to such requirement known as “excepción de arraigo”). 
  
 (C) Enforcement of the Shareholders’ Agreement in Argentina will further require (i) that the relevant Argentine courts before whom enforcement is sought be
competent under the applicable laws of Argentina to solve the disputes brought before them in connection with the Shareholders’ Agreement, (ii) compliance with the appropriate procedural requirements for enforcement thereof (which
requirements in all material respects are non-discretionary and administrative in nature), including, without limitation, exhaustion of mandatory mediation procedures pursuant to Argentine Law No. 24,573, as amended, and its regulatory decree
No. 91/98, as amended and supplemented (with the exception of, among others, bankruptcy and executory proceedings, which executory proceedings include the enforcement of foreign judgments, in which case mediation procedures remain optional for
the plaintiff), and (iii) that the Shareholders’ Agreement does not violate public policy as defined under the applicable laws of Argentina (including Argentine Law No. 24,871) (and we opine such agreement does not violate such public
policy). The enforceability by Argentine courts of documents not governed by Argentine law is subject to the validity and enforceability thereof under the applicable laws that govern such non-Argentine law-governed documents. Furthermore,
enforcement of foreign judgments may be limited by the Enforceability Exceptions. 
  
 (D) The rights and obligations of Siderar and the other parties under the Shareholders’ Agreement are subject to the effect of the Enforceability Exceptions. In particular, in the case of 
  

 F-6 








 a bankruptcy declared against Siderar, certain unsecured creditors (including without limitation, certain creditors of
the bankrupt party and creditors under and in connection with taxes, court related expenses, salaries and social security charges) are granted a preferential treatment. Also, in the case of bankruptcy declared against Siderar, the allowance of
creditors whose claims are payable outside Argentina and which do not belong to a foreign bankruptcy proceeding is conditional upon submission of evidence that, reciprocally, a creditor whose claim is payable in Argentina may be allowed and paid
pari passu in bankruptcy proceedings commenced in the country where the claim of the former is payable, provided that if Siderar is also declared bankrupt outside Argentina, the creditors who belong to the foreign bankruptcy will be entitled
to claim only on the balance of assets in Argentina remaining after the claims of all creditors in the Argentine bankruptcy proceeding have been satisfied. 
  
 (E) Nothing herein is to be taken as an indication that the remedy of an order for specific performance or the issue of an injunction would be available in a court in
Argentina. 
  
 (F) The exercise and enforceability by the parties to the
Shareholders’ Agreement (other than Siderar) of their rights thereunder is subject to emergency laws, general principles of law (“principios generales de derecho”) or other general principles of equity now in effect, including
but not limited to the application of Section 1071 of the Argentine Civil Code, as amended (which may render certain provisions unenforceable where their enforcement under the circumstances would be deemed unreasonable or where their breach
would be deemed immaterial), Section 1198 of the Argentine Civil Code, as amended (which may render certain provisions unenforceable where their enforcement would violate the implied covenant of good faith and fair dealing), including recently
enacted rules regarding the sharing of efforts principle (“principio del esfuerzo compartido”), and Section 218 of the Argentine Commercial Code, as amended (pursuant to which a court may, at its discretion, revise ambiguous
terms of a contract in the manner it deems most equitable), all that irrespective of the law applicable to the Shareholders’ Agreement. Such principles are of general application, and in applying such principles a court, among other things,
might decline to order Siderar to perform covenants or may require that the parties to the Shareholders’ Agreement act with reasonableness and good faith. Such a requirement might be applied, among other situations, to the provisions of any
agreement purporting to authorize conclusive determinations by any party thereto. 
  
 (G) This opinion letter is limited to the matters stated herein and no opinions may be implied as inferred beyond the matters expressly stated herein. 
  

We are members of the Bar of the City of Buenos Aires and the foregoing opinion is limited to the laws of Argentina in force at the date hereof.
Accordingly, we have assumed that there is nothing in any other law that affects our opinion. In particular, we have made no independent investigation of any laws other than the laws of Argentina as a basis for the opinion stated herein and do not
express or imply any opinion on such laws. 
  
 This opinion is
rendered solely for your benefit in connection with the Shareholders’ Agreement and for the benefit of any other person to whom you may assign an interest in any Loan in connection with the above matters (provided that this opinion
speaks solely as of the date hereof) and may not be furnished to, quoted or relied upon by any other 
  

 F-7 








 person or entity (other than each bank, financial institution or institutional lender that becomes a party to the Credit
Agreement from time to time) for any purpose without our prior written consent. 
  
 Very truly yours,

 Re: Shareholder Letter Agreement 
  
 Ladies and Gentlemen: 
  
 Reference is made to the Second Amended and Restated Credit Agreement (the “Credit Agreement”), dated as of August 16, 2005, by and among I.I.I. – Industrial Investments, Inc., as Borrower (the
“Borrower”), the lenders named therein, as Lenders, Citibank, N.A. as Collateral Agent, and Citibank, N.A. as Administrative Agent. All capitalized terms used but not otherwise defined herein shall have the meaning assigned to them in the
Credit Agreement. 
  
 By signing below, (i) Siderar S.A.I.C.
(“Siderar”) hereby grants to the Collateral Agent on behalf of the Secured Parties certain rights (set forth below) in respect of all shares of Hylsamex, S.A. de C.V. (“Hylsamex”) held by Siderar and Inversiones Basilea S.A.
(“Basilea”) from time to time, and agrees to certain restrictions set forth below regarding such shares, (ii) Basilea hereby grants to the Collateral Agent on behalf of the Secured Parties certain rights (set forth below) in respect
of all shares of Hylsamex held by Basilea from time to time, and agrees to certain restrictions set forth below regarding such shares, (iii) the Borrower hereby agrees to take certain actions set forth below, and (iv) the Borrower and the
Collateral Agent (which is hereby directed by the Borrower to grant such rights) hereby agree to grant to Siderar certain rights set forth below in respect of certain sales pursuant to foreclosure by the Collateral Agent upon shares of Hylsamex held
by the Borrower and pledged to the Collateral Agent. 
  


	14	All references to Basilea shall be deleted in the event that Basilea does not acquire any shares of Hylsamex.

 Drag Along 
  
 If, at any time following an Event of Default and in connection with an authorized foreclosure on the Collateral, in accordance with the terms of the Credit Agreement and
the Stock Pledge Agreement, the Collateral Agent proposes to sell, or to otherwise dispose of, to a third party (the “Purchaser”) in a bona fide arms’ length transaction (a “Drag Along Sale”) all, but not less than
all, of the Collateral pursuant to the terms of the Credit Agreement, then the Collateral Agent shall have the right (the “Drag Along Right”), by delivering a written notice to each of Siderar and Basilea, to require each of Siderar and
Basilea to sell, and Siderar to cause Basilea to sell, concurrently with the sale by the Collateral Agent of the Collateral, all, but not less than all, of the equity interests (whether shares, interests, participations or other equivalents (however
designated, whether voting or non-voting), any and all equivalent ownership interests, and any and all warrants, options or other rights to acquire (whether through conversion, exchange or otherwise) any of the foregoing) in Hylsamex held by Siderar
and Basilea (together with the Collateral, the “Offered Shares”) upon the same terms and conditions and at a price per share equal to the price per share payable by the Purchaser to the Collateral Agent for the Collateral, which purchase
price shall be payable in respect of their shares to Siderar and Basilea in cash, if paid to the Collateral Agent in cash, in Dollars in a New York based account and in kind, if paid to the Collateral Agent in kind. The Collateral Agent shall
exercise such right upon written direction of the Administrative Agent. Notwithstanding anything to the contrary herein, such purchase price shall be paid to an account of Siderar (and Siderar shall make available to the Collateral Agent an account)
located in New York, New York, or if no such account is available, in Europe. In connection with any such Drag Along Sale, the Collateral Agent or any agent acting on its behalf shall (i) select as directed in writing by the Administrative
Agent at least three bidders of recognized standing in the steel industry to participate in any sales process for the Offered Shares and (ii) use commercially reasonable efforts to obtain from such bidders a binding offer to purchase the
Offered Shares that includes material terms and conditions, including the price per share, thereof. 
  
 Right of First Refusal 
  
 In the event that the Collateral Agent exercises its Drag Along Right in connection with a Drag Along Sale, the Collateral Agent shall give written notice to Siderar of

 SEGUNDA. Derechos
Económicos y Corporativos; Suscripción. (a) Las partes convienen que el Deudor Prendario tendrá el derecho de ejercer cualesquiera y todos los derechos corporativos (incluyendo los derechos de voto) y, sujeto a lo

Deudor Prendario, por medio del presente, conviene en que los derechos corporativos y económicos correspondientes a las Acciones Hylsamex, serán ejercidos por el Acreedor Prendario. Los derechos corporativos deberán ser
ejercidos por el Deudor Prendario o el Acreedor Prendario, según sea el caso, sujeto a las limitantes expresamente establecidas en este Contrato y el Contrato de Crédito. En el caso del Acreedor Prendario, dichos derechos serán

descritas en dicha Cláusula Séptima, hayan quedado remanentes respecto del efectivo pignorado o los intereses generados conforme a esta Cláusula, el Acreedor Prendario tendrá la obligación de entregar al Deudor

 The
following provisions #1-11 shall be deemed the “Subordination Terms”. 
  

	 	1.	All payment obligations of the Borrower hereunder (whether for principal, interest or otherwise) (the “Subordinated Obligations”) are and shall be expressly subordinated
and subject in right of payment to the prior indefeasible repayment in full of all the obligations of the Borrower now or hereafter existing under the Credit Agreement (the “Senior Obligations”) (which, as used herein, shall include
without limitation the obligations to pay principal and interest on such Senior Obligations, and all commissions, fees, indemnities, prepayment premiums and other amounts payable to the Administrative Agent or any lenders or sureties (such lenders
or sureties, the “Senior Lenders”), agents or trustees under any Loan Documents with respect to such Senior Obligations, and post-petition interest and post-petition attorneys’ fees and costs, whether or not allowable in bankruptcy,
in each case to the extent such items constitute Senior Obligations). 

  

	 	2.	The Borrower and the Lender hereby agree that no payment or prepayment shall be made by or on behalf of the Borrower for or on account of any Subordinated Obligations, and the
Lender shall not ask, demand, sue for, take or receive from the Borrower, directly or indirectly, in cash, other property, or any rights or by set-off or in any other manner, including, without limitation, from or by way of collateral, payment of
all or any of the Subordinated Obligations, unless and until the Senior Obligations shall have been indefeasibly repaid in full in cash. 

  

	 	3.	In the event of (i) any insolvency or bankruptcy case or proceeding in connection therewith, relative to the Borrower or to its creditors as such, or to its assets, or
(ii) any 

  

 L-1 








 liquidation, dissolution or other winding up of the Borrower, whether partial or complete and whether
voluntary or involuntary and whether or not involving insolvency or bankruptcy or (iii) any assignment for the benefit of creditors or any other marshaling of assets and liabilities of the Borrower, then and in any such event the Senior Lenders
shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Obligations or under the Credit Agreement before the Lender shall be entitled to receive any payment on account of the Loan (whether in
respect of principal, interest premium, fees, indemnities, commissions or otherwise) and to that end, any payment or distribution of any kind or character, whether in cash, property or securities which may be payable or deliverable in respect of the
Loan in any such case, proceeding, dissolution, liquidation or other winding up or event shall instead be paid or delivered to the Senior Lenders for application to the Senior Obligations, whether or not due, until the Senior Obligations shall have
first been fully paid and satisfied in cash. 
  

	 	4.	If any event of default (or event or condition that with the giving of notice or passage of time or both would constitute an event of default) shall have occurred and be continuing
under the Credit Agreement, then no payment shall be made by the Borrower on or in respect of the Loan, unless and until such event of default, event or condition shall have been remedied or waived. 

  

	 	5.	In the event that the Lender receives on account or in respect of the Loan or otherwise after the occurrence and during the continuance of an event of default under the Credit
Agreement any distribution of assets by the Borrower or payment by or on behalf of the Borrower of any kind or character, whether in cash, securities or other property, such receipts shall be received in trust for the benefit of the Senior Lenders,
shall be segregated from other funds and property held by the Lender and shall be forthwith paid over to the Administrative Agent under the Credit Agreement for the account of the Senior Lenders in the same form as so received (with any necessary
endorsement or assignment) to be applied (in the case of cash) to, or held as collateral (in the case of non-cash property or securities) for, the repayment or prepayment of the Senior Obligations. In the event of failure of the Lender to make any
such endorsement or assignment, the Senior Lenders irrevocably are authorized and empowered by and on behalf of the Lender to make the same. 

  

	 	6.	The Lender (i) irrevocably authorizes and empowers (without imposing any obligation on) Senior Lenders (or their agents, attorneys or trustees) to demand, sue for, collect,
receive and receipt for all payments and distributions on or in respect of its Subordinated Obligations which are required to be paid or delivered to the Senior Lenders, as provided herein, and to file and prove all claims therefore and take all
such other action, in the name of the Lender or otherwise, as Senior Lenders may determine to be necessary or appropriate for the enforcement of the subordination terms contained in this Agreement, (ii) irrevocably authorizes and empowers
(without imposing any obligation) Senior Lenders (or their agents, attorneys or trustees) to vote the Subordinated Obligations (including, without limitation, voting the Subordinated Obligations in favor of or in opposition to any matter which may
come before any meeting of creditors of the Borrower generally or in connection with, or in anticipation of, any insolvency or bankruptcy case or proceeding, or any proceeding under any laws relating to the relief of 

  

 L-2 








 debtors, readjustment of Indebtedness, arrangements, reorganizations, compositions or extensions relative
to the Borrower) and (iii) agrees to execute and deliver to Senior Lenders all such further instruments confirming the above authorization, and all such powers of attorney, proofs of claim, assignments of claim and other instruments, and to
take all such other action, as may be requested by Senior Lenders in order to enable Senior Lenders to enforce all claims upon or in respect of the Subordinated Obligations. 
  

	 	7.	The Lender agrees, for the benefit of each Senior Lender, that they will give each Senior Lender prompt notice of any default by the Borrower in respect of the Subordinated
Obligations. 

  

	 	8.	Until the repayment in full of the Senior Obligations, the Lender shall not transfer, sell, assign, pledge, encumber or otherwise dispose of any of the Subordinated Obligations,
unless such transfer, sale, assignment, pledge, encumbrance or disposition is made with the prior written consent of the Administrative Agent under the Credit Agreement. 

  

	 	9.	No failure on the part of Senior Lenders and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof by Senior Lenders, nor shall any single
or partial exercise of any right, remedy or power hereunder, preclude any other or future exercise of Senior Lenders of any other right, remedy or power. Each and every right, remedy and power granted to Senior Lenders, or allowed Senior Lenders by
law or other agreement shall be cumulative and not exclusive, and may be exercised by Senior Lenders, from time to time. 

  

	 	10.	Without in any way limiting the generality of the foregoing paragraph, at any time, without the consent of or notice to the Lender, without incurring responsibility or liability to
the Lender and without impairing or releasing the subordination provided herein or the obligations hereunder of the Lender, the Senior Lenders may do any one or more of the following: (i) change the manner, place or terms of payment of or
extended the time of payment of, or renew or alter, Senior Obligations or any collateral security or guaranty therefor, or otherwise amend or supplement in any manner Senior Obligations or any instruments evidencing the same or any agreement under
which Senior Obligations are outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Obligations; (iii) release any Person liable in any manner for the Senior
Obligations; and (iv) exercise or refrain from exercising any rights against the Borrower and any other Person. The Lender unconditionally waives notice of the incurring of Senior Obligations or any part thereof. 

  

	 	11.	The Lender, at its own cost, shall take any further action as the Senior Lenders may reasonably request in order to carry out more fully the intent and purpose of the Subordination
Terms. 

  
 OTHER TERMS

  
 Notwithstanding any provision of this Agreement, it is agreed hereunder
that the Lender shall have the right at any time, at its sole election and discretion, to require the Borrower or the Authorized Assignee, as the case may be, to convert the Subordinated Obligations into Stock as provided under [the relevant
conversion provision in the Subordinated Loan agreement].

 EXECUTION 
  
  
 AMENDMENT No. 1 dated as of September 21, 2005 (the
“Amendment”) among I.I.I. – INDUSTRIAL INVESTMENTS INC., a British Virgin Islands business company (the “Borrower”), CITIBANK, N.A., as administrative agent, (the “Administrative Agent”),
CITIBANK, N.A., as collateral agent, (the “Collateral Agent”) and the lenders listed below (the “Lenders”). 
  
 WHEREAS, pursuant to the Second Amended and Restated Credit Agreement dated as of August 16, 2005 (the “Agreement”), among the
Borrower, the Administrative Agent, the Collateral Agent and the Lenders, the Lenders made certain loans to I.I.I. pursuant to the terms and subject to the conditions set forth therein, capitalized terms used but not defined herein having the
meanings assigned in the Agreement; 
  
 WHEREAS, the Borrower, the
Administrative Agent, the Collateral Agent and the Majority Lenders desire to amend Section 5.02(f) of the Agreement in order to clarify the matters set forth therein; and 
  
 WHEREAS, under Section 8.01 of the Agreement, the Agreement may be amended with the written consent of the Majority
Lenders; 
  
 NOW, THEREFORE, the Borrower, the Administrative
Agent, the Collateral Agent and the Majority Lenders hereby agree as follows: 
  
 1. Section 5.02(f) of the Agreement shall be replaced in its entirety by the following new Section 5.02(f): 
  
 “(f) Investments in Other Persons. Make or hold, or permit any of its Relevant Subsidiaries to make or hold, any Investment in any Person,
except: 
  
 (i) Investments by the Borrower and

 (ii)
Investments existing on the date hereof and described on Schedule 5.02(f) hereto and Investments in the Anticipated Acquired Shares and in any Equity Interests received in exchange for the Amazonia, Hylsa Latin and Ylopa Equity Purchase Price,

  
 (iii) Investments made by the Borrower or any
Material Subsidiary to the extent otherwise permitted hereunder which are part of, or in lines of business which are substantially the same as, the lines of business of one or more of the Borrower and its Material Subsidiaries as of the date hereof
(which may include, for the avoidance of doubt, Investments by the Borrower in Debt of a Material Subsidiary); provided, that all consideration paid by the Borrower in respect of any Investment made by the Borrower pursuant to this clause
(iii) shall consist solely of amounts available in respect of Excess Cash of the Borrower after application of such Excess Cash (and of all amounts deducted in connection with the calculation thereof) pursuant to Section 2.05 hereof except
that (A) in the case of any Allowed Investment made by the Borrower, such consideration may 
  

 M-2 








 consist of Equity Interests of the Borrower, (B) upon and after the occurrence of the Zoompart
Succession, the Borrower may make and hold Investments in I.I.I. consisting of Equity Interests in I.I.I. and/or Subordinated Loans to I.I.I. permitted under Section 5.02(b)(w) hereof, the consideration for which may consist of the assumption
of the Subordinated Loans of I.I.I. as required under Section 8.08 hereof and (C) the Borrower may make and hold Investments in I.I.I. consisting of Equity Interests in I.I.I. in consideration for and in connection with the Zoompart
Succession; and 
  
 (iv) Investments by any
Subsidiary in Debt owing to it by any direct or indirect holder of Equity Interests of such Subsidiary for the purpose of upstreaming Distributions by such Subsidiary to such holder of Equity Interests; provided that any such Investment in
Debt of a Person other than the Borrower or a Subsidiary of the Borrower shall be made (1) contemporaneously with an Investment by such Subsidiary in Debt incurred by the Borrower or a Subsidiary of the Borrower pursuant to
Section 5.02(b)(y) and (2) in an amount not to exceed the amount resulting from applying the percentage of beneficial ownership in such Subsidiary of such holder of Equity Interests of such Subsidiary to the total amount of Investments of
the same type made on the same date.” 
  
 2. Except as
expressly set forth herein, the Agreement shall remain in full force and effect. 
  
 3. This Amendment shall become effective on and as of the first Business Day on the Administrative Agent shall have received counterparts of this letter executed by Ternium, the Administrative Agent, the Collateral
Agent and Lenders constituting the Majority Lenders, or, as to any such Lender, advice satisfactory to the Administrative Agent that such Lender has executed this letter. 
  
 4. This Amendment shall be governed by and shall be interpreted and construed in accordance with the law of the State of New
York. 
  
 5. If any provision of this Amendment is held invalid,
illegal or unenforceable in any jurisdiction, to the extent permitted by law, such provision shall, as to that jurisdiction, be ineffective to the extent of that prohibition or unenforceability without invalidating the remaining provisions of this
Amendment or affecting the validity or enforceability of that provision in any other jurisdiction. 
  
 6. The parties may execute this Amendment in counterparts, and each of which is deemed an original and all of which taken together constitute only one
agreement.
