Interest Act (Canada)

For the purposes of the Interest Act (Canada) and disclosure under such Act:

(a)

wherever interest to be paid under this Agreement is to be calculated on the basis of any period of time that is less than a calendar year (a "deemed year"), such rate of interest shall be expressed as a yearly rate by multiplying such rate of interest for the deemed year by the actual number of days in the calendar year in which the rate is to be ascertained and dividing it by the number of days in the deemed year; and

(b)

the Borrower and each other Obligor confirms that it fully understands and is able to calculate the rate of interest applicable to the Facility based on the methodology for calculating per annum rates provided for in this Agreement. The Lender agrees that, if requested in writing by the Borrower, it shall calculate the nominal and effective per annum rate of interest on any Loan outstanding at any time and provide such information to the Borrower promptly following such request; provided that any error in any such calculation, or any failure to provide such information on request, shall not relieve the Borrower or any other Obligor of any of its obligations under this Agreement or any other Finance Document, nor result in any liability to the Lender. Each Obligor hereby irrevocably agrees not to plead or assert, whether by way of defence or otherwise, in any proceeding relating to the Finance Documents, that the interest payable under the Finance Documents and the calculation thereof has not been adequately disclosed to the Obligors, whether pursuant to Section 4 of the Interest Act (Canada) or any other applicable law or legal principle.

9.6

Maximum Interest

In the event that any provision of this Agreement or any other Finance Document would oblige the Borrower or any other Obligor to make any payment of interest or any other payment which is construed by a court of competent jurisdiction to be interest in an amount or calculated at a rate which would be prohibited by applicable law or regulation or would result in a receipt by the Lender of interest at a criminal rate (as such terms are construed under the Criminal Code (Canada)), then notwithstanding such provision, such amount or rate shall be deemed to have been adjusted nunc pro tunc to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by applicable law or regulation or so result in a receipt by the Lender of interest at a criminal rate, such adjustment to be effected, to the extent necessary as follows:

(a)

first, by reducing the amount or rate of interest required to be paid under this Agreement; and

(b)

thereafter, by reducing any fees, commissions, premiums or other amounts required to be paid to the Lender which would constitute interest for the purposes of Section 347 of the Criminal Code (Canada).

If, notwithstanding the provisions of this Clause and after giving effect to all adjustments contemplated thereby, the Lender shall have received an amount in excess of the maximum permitted by applicable law, then such excess shall be applied by the Lender to the reduction of the principal balance of the outstanding principal of the Loan and not to the payment of interest, or if such excessive interest exceeds such principal balance, such excess shall be refunded to the Borrower or Obligor, as applicable.

SECTION 6

ADDITIONAL PAYMENT OBLIGATIONS

12.

TAX GROSS-UP AND INDEMNITIES; FATCA

12.1

Tax gross-up and indemnities

(a)

Each payment by or on account of any obligation of an Obligor under any Finance Document shall be made free and clear of and without deduction or withholding for any Taxes, except as required by applicable law. If an Obligor shall be required by applicable law to deduct or withhold any Tax from any such payment, such Obligor shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable shall be increased as necessary so that, after making all required deductions or withholding (including deductions or withholding applicable to additional sums payable under this Clause 12.1), the Lender or any other applicable recipient of such payment receives an amount equal to the sum it would have received had no such deductions or withholding been made.

(b)

In addition, the Obligors shall pay all Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c)

The Obligors shall jointly and severally indemnify the Lender and every other recipient of a payment under any Finance Document, within ten days after written demand therefor, for the full amount of any Indemnified Taxes paid or payable by the Lender or recipient (as applicable) on or with respect to any payment under the Finance Documents (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Clause 12.1) and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by the Lender shall be conclusive absent manifest error.

(d)

As soon as practicable after any payment of Indemnified Taxes by an Obligor to a Governmental Authority, the Obligor shall deliver to the Lender the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Lender.

(e)

If the Lender is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Finance Document, the Lender shall deliver to the Borrower, at the time or times reasonably requested by the Borrower, such properly completed and executed documentation reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, the Lender, if reasonably requested by the Borrower, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower as will enable the Borrower to determine whether or not the Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation shall not be required if in the Lender's reasonable judgment such completion, execution or submission would subject the Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of the Lender.

(f)

The Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower in writing of its legal inability to do so.

(g)

The Borrower shall not be obligated to indemnify or pay any additional amount with respect to Taxes under this Clause 12.1 to the extent such Taxes are imposed because the Lender fails to timely provide the forms or certificates required under this Clause 12.1 (and Indemnified Taxes shall be deemed not to include any such Taxes).

(h)

If, within the period of 2 years following the Termination Date, the Lender receives a refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by an Obligor or with respect to which an Obligor has paid additional amounts in each case pursuant to this Clause 12.1 or that, because of the payment of such Indemnified Taxes or Other Taxes, it has benefited from a reduction in Excluded Taxes otherwise payable by it, it shall pay over the amount of such refund or reduction to the applicable Obligor (but only to the extent of indemnity payments made, or additional amounts paid, by the applicable Obligor under this Clause 12.1 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund or reduction), net of all reasonable out-of-pocket expenses (including Taxes) of the Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). The Borrower, upon the request of the Lender, agrees to repay in a timely manner (and in any event within 20 days of the Lender’s request), the amount paid over to the applicable Obligor (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Lender if Lender is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the Lender be required to pay any amount to an indemnifying party pursuant to this paragraph (h) the payment of which would place the Lender in a less favorable net after Tax position than the Lender would have been in if the Tax subject to indemnification and giving rise to such refund or reduction had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts giving rise to such refund or reduction had never been paid. This paragraph (h) shall not be construed to require the Lender to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person.

12.2

any fiduciary duty; or

(iii)

any duty of confidentiality.

(d)

If a Party fails to confirm whether or not it is a FATCA Exempt Party or to supply forms, documentation or other information requested in accordance with paragraph (a)(i) or (a)(ii) above (including, for the avoidance of doubt, where paragraph (c) above applies), then such Party shall be treated for the purposes of the Finance Documents (and payments under them) as if it is not a FATCA Exempt Party until such time as the Party in question provides the requested confirmation, forms, documentation or other information.

12.3

FATCA Deduction

(a)

Each Party may make any FATCA Deduction it is required to make by FATCA, and any payment required in connection with that FATCA Deduction, and no Party shall be required to increase any payment in respect of which it makes such a FATCA Deduction or otherwise compensate the recipient of the payment for that FATCA Deduction.

(iv)

a reduction of any amount due and payable under any Finance Document,

(b)

The obligations of an Obligor in respect of any sum due in the Original Currency from it to the Lender under any of the Finance Documents shall, notwithstanding any judgment in any Other Currency, be discharged only to the extent that on the Business Day following receipt by the Lender of any sum adjudged to be so due in the Other Currency, the Lender may, in accordance with normal banking procedures, purchase the Original Currency with such Other Currency. If the amount of the Original Currency so purchased is less than the sum originally due to the Lender in the Original Currency, such ▇▇▇▇▇▇▇ agrees, as a separate obligation and notwithstanding the judgment, to indemnify the Lender, against any loss, and, if the amount of the Original Currency so purchased exceeds the sum originally due to the Lender in the Original Currency, the Lender shall remit such excess to such Obligor.

(c)

If any sum due from an Obligor under the Finance Documents (a “Sum”), or any order, judgment or award given or made in relation to a Sum, has to be converted from the currency (the “First Currency”) in which that Sum is payable into another currency (the “Second Currency”) for the purpose of:

(i)

making or filing a claim or proof against that Obligor; or

(ii)

obtaining or enforcing an order, judgment or award in relation to any litigation or arbitration proceedings,

SECTION 7

GUARANTEE

17.

GUARANTEE AND INDEMNITY

Guarantee and indemnity

The Guarantor irrevocably and unconditionally jointly and severally, until the Guarantee Termination Date:

(a)

guarantees to the Lender punctual performance by the Borrower of all the Borrower’s obligations under the Finance Documents;

(b)

undertakes with the Lender that whenever the Borrower does not pay any amount when due under or in connection with any Finance Document, the Guarantor shall immediately on demand pay that amount as if it was the principal obligor; and

(c)

agrees with the Lender that if any obligation guaranteed by it is or becomes unenforceable, invalid or illegal, it will, as an independent and primary obligation, indemnify the Lender immediately on demand against any cost, loss or liability it incurs as a result of the Borrower not paying any amount which would, but for such unenforceability, invalidity or illegality, have been payable by it under any Finance Document on the date when it would have been due. The amount payable by the Guarantor under this indemnity will not exceed the amount it would have had to pay under this Clause 17 if the amount claimed had been recoverable on the basis of a guarantee.

17.2

Continuing guarantee

This guarantee is a continuing guarantee until the Guarantee Termination Date and subject to the occurrence of the Guarantee Termination Date will extend to the ultimate balance of sums payable by any Obligor under the Finance Documents, regardless of any intermediate payment or discharge in whole or in part.

17.3

Reinstatement

If any discharge, release or arrangement (whether in respect of the obligations of any Obligor or any security for those obligations or otherwise) is made by the Lender in whole or in part on the basis of any payment, security or other disposition which is avoided or must be restored in insolvency, restructuring, liquidation, administration or otherwise, without limitation, then the liability of the Guarantor under this Clause 17 will continue or be reinstated as if the discharge, release or arrangement had not occurred, provided that, there shall be no such reinstatement following the Guarantee Termination Date.

17.4

Waiver of defences

The obligations of the Guarantor under this Clause 17 will not be affected by an act, omission, matter or thing which, but for this Clause, would reduce, release or prejudice any of its obligations under this Clause 17 (without limitation and whether or not known to it or the Lender) including:

(a)

any time, waiver or consent granted to, or composition with, any Obligor or other person;

(b)

the release of any other Obligor or any other person under the terms of any composition or arrangement with any creditor of any member of the Group;

(c)

the taking, variation, compromise, exchange, renewal or release of, or refusal or neglect to perfect, take up or enforce, any rights against, or security over assets of, any Obligor or other person or any non-presentation or non-observance of any formality or other requirement in respect of any instrument or any failure to realise the full value of any security;

(d)

any incapacity or lack of power, authority or legal personality of or dissolution or change in the members or status of an Obligor or any other person;

(e)

any amendment, novation, supplement, extension, restatement (however fundamental and whether or not more onerous) or replacement of any Finance Document or any other document or security including without limitation any change in the purpose of, any extension of or any increase in any facility or the addition of any new facility under any Finance Document or other document or security;

(f)

any unenforceability, illegality or invalidity of any obligation of any person under any Finance Document or any other document or security; or

(g)

any insolvency, restructuring or similar proceedings.

17.5

Immediate recourse

The Guarantor waives any right it may have of first requiring the Lender (or any trustee or agent on its behalf) to proceed against or enforce any other rights or security or claim payment from any person before claiming from the Guarantor under this Clause 17. This waiver applies irrespective of any law or any provision of a Finance Document to the contrary. For avoidance of doubt, the Lender will have no recourse to the Guarantor following the Guarantee Termination Date.

The Guarantor's obligation to make payment hereunder shall be deemed to be that of a “fiadora e principal pagadora, solidariamente responsável” with the Seller until all amounts which may be or become payable have been paid in full. For such purposes, the Guarantor expressly waives and renounces, to the fullest extent permitted by applicable law, any and all rights and/or benefits it may have under Article 333 and Articles 366, 821, 827, 829, 834, 835, 837, 838 and 839 of the Brazilian Civil Code and Articles 130 and 794 of the Brazilian Code of Civil Procedure.

17.6

Appropriations

Until the earlier of (x) the Guarantee Termination Date and (y) the date that all amounts which may be or become payable by the Obligors under or in connection with the Finance Documents have been irrevocably paid in full, the Lender (or any trustee or agent on its behalf) may:

(a)

refrain from applying or enforcing any other moneys, security or rights held or received by the Lender (or any trustee or agent on its behalf) in respect of those amounts, or apply and enforce the same in such manner and order as it sees fit (whether against those amounts or otherwise) and the Guarantor shall not be entitled to the benefit of the same; and

(b)

hold in an interest-bearing suspense account any moneys received from the Guarantor or on account of the Guarantor’s liability under this Clause 17.

17.7

Deferral of Guarantor’ rights

Until the earlier of (x) the Guarantee Termination Date and (y) all amounts which may be or become payable by the Obligors under or in connection with the Finance Documents have been irrevocably paid in full and unless the Lender otherwise directs, the Guarantor will not exercise any rights which it may have acquired by reason of performance by it of its obligations under the Finance Documents or by reason of any amount being payable, or liability arising, under this Clause 17:

(a)

to be indemnified by any other Obligor;

(b)

to claim any contribution from any other guarantor of any Obligor’s obligations under the Finance Documents;

(c)

to take the benefit (in whole or in part and whether by way of subrogation or otherwise) of any rights of the Lender under the Finance Documents or of any other guarantee or security taken pursuant to, or in connection with, the Finance Documents by the Lender;

(d)

to bring legal or other proceedings for an order requiring any Obligor to make any payment, or perform any obligation, in respect of which the Guarantor has given a guarantee, undertaking or indemnity under Clause 17.1 (Guarantee and Indemnity);

(e)

to exercise any right of set-off against any Obligor; and/or

(f)

to claim or prove as a creditor of any Obligor in competition with the Lender .

If the Guarantor receives any benefit, payment or distribution in relation to such rights it shall hold that benefit, payment or distribution to the extent necessary to enable all amounts which may be or become payable to the Lender by the Obligors under or in connection with the Finance Documents to be repaid in full on trust for the Lender and shall promptly pay or transfer the same to the Lender or as the Lender may direct for application in accordance with Clause 24 (Payment mechanics).

17.8

This guarantee is in addition to and is not in any way prejudiced by any other guarantee or security now or subsequently held by the Lender.
