2.2 No Release or Discharge. This Guaranty is a direct and primary obligation of Guarantor and shall be an irrevocable, unconditional, absolute and continuing guaranty, irrespective of the following potential defenses:

into the Agreement or such other documents or the failure of the Agreement or such other documents to be duly authorized and executed by Obligor and its signatories;

2.2.2 any postponement or extension of the date on which any payment must be made pursuant to the Agreement or postponement or extension of the date on which any act must be performed by Obligor thereunder, provided that any such postponement or extension shall be deemed to apply to the Guarantor’s obligations hereunder in the same way that it applies to Obligor’s obligations under the Agreement;

2.2.3 whether or not Guarantor received direct notice of or consented to any modification, amendment, supplement, renewal or waiver of the Agreement or any of the terms or conditions of the Agreement, including under a Change Order, provided that the Guaranteed Obligations shall not be greater than the obligations of Obligor under the Agreement, as the Agreement may be so modified, amended, supplemented, renewed or waived without Guarantor’s consent;

2.2.10 any election of remedies by Beneficiary, even if such election of remedies impairs or destroys Guarantor’s right of subrogation against Obligor;

2.2.11 any merger, consolidation, termination of or change in corporate existence, structure or ownership of Obligor or Guarantor, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting Obligor or its assets; or

Execution Version

without notice to or further assent by Guarantor, who shall remain bound by this Guaranty, which shall remain in full force and effect until all of the Guaranteed Obligations have been paid in full or otherwise extinguished.

No action which Beneficiary shall take or fail to take in connection with the Guaranteed Obligations, nor any course of dealing with Obligor or any other person, shall release Guarantor’s obligations hereunder, affect this Guaranty in any way, or afford Guarantor any recourse against Beneficiary. This Guaranty is in no way conditioned or contingent upon any attempt to collect from or enforce performance or payment by Obligor or upon any other event, contingency or circumstance whatsoever. Beneficiary shall not be obligated to take any action, obtain any judgment or file any claim prior to enforcing this Guarantee. Beneficiary shall not be obligated to file any claim relating to the Obligations in the event that Obligor becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of Beneficiary to so file shall not affect Guarantor’s obligations hereunder.

This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations are annulled, set aside, invalidated, declared to be fraudulent or preferential, rescinded or must otherwise be returned, refunded or repaid by Beneficiary upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of Obligor or any other guarantor, or upon or as a result of the appointment of a receiver or conservator of, or trustee for Obligor or any other guarantor or any substantial part of its property or otherwise, all as though such payment or payments had not been made

2.3 Waiver of Rights. Subject to the limitations expressly set forth in this Guaranty, Guarantor understands and agrees that the guaranty contained in Section 2.1 shall be a continuing guaranty. Guarantor hereby expressly waives.

2.3.1 notice of acceptance of this Guaranty, of the creation or existence of any of the Guaranteed Obligations, of any of the matters described in Section 2.2 and of any action by Beneficiary in reliance hereon or in connection herewith;

2.3.2 notice of the entry into the Agreement between Obligor and Beneficiary and of any amendments, supplements or modifications thereto; or any waiver of consent under the Agreement, including waivers of the payment and performance of the obligations thereunder;

2.3.3 notice of any increase, reduction or rearrangement of Obligor’s obligations under the Agreement or any extension of time for the payment of any sums clue and payable to Beneficiary under the Agreement;

2.3.4 presentment, demand for payment, notice of acceptance, notice of dishonor or nonpayment, protest and notice of protest or any other notice with respect to the Guaranteed Obligations; and

2.3.5 any requirement that suit be brought against, or any other remedy or action by Beneficiary be taken against, or any notice of default or other notice be given to, or any demand be made on Obligor or any other person, or that any other action be taken or not taken as

Execution Version

a condition to Guarantor’s liability for the Guaranteed Obligations under this Guaranty or as a condition to the enforcement of this Guaranty against Guarantor.

2.4 No Subrogation. Guarantor will not exercise and irrevocably agrees to waive any rights against Obligor which it may acquire by way of subrogation, reimbursement, exoneration, contribution or indemnification in connection with this Guarantee by any payment made hereunder or otherwise, until all Guaranteed Obligations shall have been fully and indefeasibly paid and performed. If (a) Guarantor makes payment to Beneficiary of all or any part of the Guaranteed Obligations and (b) all of the then outstanding Guaranteed Obligations shall have been paid in full, Beneficiary shall, at Guarantor’s request, execute and deliver to Guarantor documents to evidence the transfer by subrogation to Guarantor of any interest in the Guaranteed Obligations resulting from such payment by Guarantor. If any amount shall be paid to Guarantor on account of such subrogation, contribution, reimbursement or indemnity rights at any time when all of the Guaranteed Obligations and all amounts owing hereunder shall not have been performed and paid in full, such amount shall be held by Guarantor in trust for Beneficiary, segregated from other funds of Guarantor, and shall, forthwith upon receipt by Guarantor, be turned over to Beneficiary in the exact form received by Guarantor (duly endorsed by Guarantor to Beneficiary, if required), to be applied against the Guaranteed Obligations, whether or not matured, in such order as Beneficiary may determine.

2.5 Demand and Payment. Beneficiary may provide written notice to Guarantor pursuant to Section 4.1 at any time if Obligor fails to punctually pay or perform any of the Guaranteed Obligations. There are no other requirements of notice, presentment or demand. Guarantor shall pay, or cause to be paid, such Guaranteed Obligations within ten (10) Business Days of receipt of such notice, unless, within such period, the default giving rise to such notice has been remedied. If Beneficiary is prevented from making a demand on Guarantor as a result of any applicable law, any injunction, order or other action of any court or other governmental authority or any stay, moratorium or other action in any bankruptcy, insolvency or other similar proceeding, Guarantor shall not be excused from paying and performing its obligations under this Guarantee as and when due. All payments by Guarantor hereunder shall be paid without setoff or deduction in U.S. dollars in immediately available funds to such accounts as may be designated by Beneficiary from time to time. Guarantor agrees to pay on demand all fees and out of pocket expenses (including the reasonable fees and expenses of Beneficiary’s counsel) in any way relating to the enforcement or protection of the rights of Beneficiary hereunder. Any amount due and payable hereunder shall, if not paid when due, accrue interest at the Late Payment Rate from the date such payment was due until the date such payment is made in full.

2.6 Primary Liability of Guarantor; Guarantor’s Defenses.

2.6.1 Guarantor agrees that Beneficiary may enforce this Guaranty without the necessity at any time of resorting to or exhausting any other security or collateral, or exercising or exhausting any other remedies against Obligor. This is a guaranty of payment and performance when and as due and not merely of collection.

2.6.2 Notwithstanding anything to the contrary stated herein or in the Agreement or any documents related thereto, Guarantor’s undertakings and obligations hereunder with respect to the Agreement are derivative of and not in excess of the Obligor’s

Execution Version

obligations under the Agreement and Guarantor may assert as a defense, right of set-off or counterclaim to its obligations hereunder any defense, right of set-off or counterclaim that Obligor may have to such Guaranteed Obligations under the Agreement or otherwise, even if Obligor fails to raise the same, except (i) a defense based on the discharge of the Guaranteed Obligations as to Obligor in a bankruptcy or insolvency proceeding or (ii) other defenses expressly waived hereunder.

2.7 Continuing Guaranty. Guarantor’s obligations under Section 2.1 of this Guaranty shall continue in force and effect until the Guaranteed Obligations have been fully performed or otherwise extinguished under the Agreement, at which time this Guaranty and all of Guarantor’s obligations hereunder shall terminate and expire. Guarantor agrees that any judgment between ▇▇▇▇▇▇▇ and Beneficiary under the Agreement (whether in contested litigation or arbitration or otherwise) shall be conclusive and binding on Guarantor for the purposes of determining Guarantor’s obligations under this Guaranty.

2.8 Guarantor Financial Statements. As soon as available, but in any event no later than one-hundred twenty (120) Days after the end of each applicable six (6)-month period, Guarantor shall make available to Beneficiary a copy of the audited consolidated balance sheets at the end of each such period as well as the related consolidated statements of income, retained earnings, and cash flows for such period. All financial statements delivered pursuant to this Section 2.8 shall be complete and correct in all material respects and shall be prepared in accordance with A-IFRS applied consistently throughout the periods reflected therein. If the Guarantor makes the foregoing financial statements publicly available on its website or through filings pursuant to applicable securities laws, then the requirements of this Section 2.8 shall be deemed met by the Guarantor making such financial statements publicly available in accordance with the requirements of applicable securities laws or, otherwise, in accordance with its customary practice.
