2

3.2Continuing Guarantee. This Guarantee is a continuing guarantee and will extend to the ultimate balance of sums payable by Buyer or Guarantor under or in connection with the SPA or this Guarantee, regardless of any intermediate payment or discharge in whole or in part or other matter whatsoever.

3.3Reinstatement. If any discharge, release or arrangement (whether in respect of the obligations of Buyer or Guarantor or any security for those obligations or otherwise) is made by Beneficiary in whole or in part on the basis of any payment, security or other disposition which is avoided or must be restored in insolvency, liquidation, administration or otherwise, without limitation, then the liability of Guarantor under this Guarantee will continue or be reinstated as if the discharge, release or arrangement had not occurred.

3.4Unconditional Nature of Obligations. Except as expressly provided in the proviso of Section 3.1, the obligations of Guarantor under this Guarantee shall be absolute, irrevocable and unconditional irrespective of the value, genuineness, validity, regularity or enforceability of the SPA or any other agreement or instrument referred to herein or therein or any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor and shall remain in full force and effect until the date this Guarantee terminates in accordance with Section 4.6 hereof, and without limiting the generality of the foregoing, such obligations shall not be affected, modified or impaired upon the happening from time to time of any event, including without limitation any of the following, whether or not with notice to, or the consent of, Guarantor:

(a)the waiver, surrender, compromise, settlement, release or termination of any or all of the obligations, covenants or agreements of Buyer under the SPA;

(b)the failure to give notice to Guarantor of the occurrence of a default under the SPA, except for the written demand required by Section 3.5 hereof;

(c)the waiver, compromise or release of the payment, performance or observance by Buyer or by Guarantor, respectively, of any or all of the obligations, covenants or agreements of either of them contained in the SPA or this Guarantee, as the case may be;

(g)any failure, omission, delay or lack on the part of Beneficiary to enforce, assert or exercise any right, power or remedy conferred on it in the SPA;

(h)the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all the assets, administration of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition with creditors or readjustment of, or other similar proceedings affecting Guarantor or Buyer or any of the respective assets of either of them, or any allegation or contest of the validity of this Guarantee in any such proceeding;

(i)any defense based upon any legal disability of Buyer or, to the extent permitted by law, any release, discharge, reduction or limitation of or with respect to any sums owing by Buyer or any other liability of Buyer to Beneficiary;

(j)to the extent permitted by law, the release or discharge by operation of law of Guarantor from the performance or observance of any obligation, covenant or agreement contained in this Guarantee; or

(k)the default or failure of Guarantor fully to perform any of its obligations set forth in this Guarantee;

If any payment by Buyer to Beneficiary is rescinded or must be returned by Beneficiary, the obligations of Guarantor hereunder shall be reinstated with respect to such payment.

Except as expressly set forth in the proviso of Section 3.1, no set-off, counterclaim, reduction, or diminution of any obligation, or any defense of any kind or nature which Buyer has or may have against Beneficiary shall be available hereunder to Guarantor to reduce the payments to Beneficiary under Section 3.1 of this Guarantee. Furthermore, no defense previously raised by Buyer arising out of or in connection with a Guaranteed Obligation claimed hereunder and which has been settled in Beneficiary’s favor by the dispute resolution procedures of Section 21.1 of the SPA may be raised by Guarantor and no cure period previously used by Buyer may be used by Guarantor.

Guarantor assumes responsibility for being and remaining informed of the financial condition of Buyer and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations which diligent inquiry would reveal and agrees that Beneficiary shall not have a duty to advise Guarantor of information known to it regarding such condition or any such circumstances.

3.5Proceedings Against Guarantor. In the event of a default in the payment of the Guaranteed Obligations when and as the same shall become due, Beneficiary shall have the right to proceed first and directly against Guarantor under this Guarantee without proceeding against Buyer or exhausting any other remedies which it may have. Accordingly, Guarantor waives any right it may have of first requiring Beneficiary to proceed against or enforce any other rights or security or claim payment from any person before claiming from Guarantor under this Guarantee. This waiver applies irrespective of any law or any provision of the SPA to the contrary. Notwithstanding the foregoing or anything to the contrary contained herein, Beneficiary shall deliver to Guarantor a written demand for payment of all amounts claimed by Beneficiary hereunder, which written demand shall specify in reasonable detail the basis for such demand, and Guarantor shall pay such amounts promptly, but no later than ten (10) Business Days after its receipt of such written demand.

4

3.6Subrogation. Upon payment of the Guaranteed Obligations, Guarantor shall be subrogated to the rights of Beneficiary against Buyer with respect to such Guaranteed Obligations, and Beneficiary agrees to take at Guarantor’s expense such steps as Guarantor may reasonably request to implement such subrogation, providedthat Beneficiary shall not be obligated to take any such steps and Guarantor shall not enforce any right arising by way of subrogation or exercise any other right or remedy arising by reason of any performance by it of this Guarantee, including, but not limited to, any contractual, statutory or common law rights of reimbursement, contribution or indemnity, whether against Buyer or any other Person, until the date this Guarantee terminates in accordance with Section 4.6 hereof.

3.7Costs. Guarantor agrees to pay all costs, expenses and fees, including without limitation all reasonable and documented out-of-pocket attorneys’ fees, which may be incurred by Beneficiary in enforcing or attempting to enforce this Guarantee following any default on the part of Guarantor hereunder, whether the same shall be enforced by suit or otherwise.

3.8Existence of Guarantor; Consolidation, Merger, Sale or Transfer. Guarantor covenants that so long as it has any outstanding obligations under this Guarantee, it will maintain its existence, will not dissolve, sell or otherwise dispose of all or substantially all of its assets and will not consolidate with or merge into another corporation or permit one or more other corporations to consolidate with or merge into it; providedthat Guarantor may, without violating the covenants contained in this Section 3.8, consolidate with or merge into another corporation or permit one or more other corporations to consolidate with or merge into it, or sell or otherwise transfer to another corporation all or substantially all of its assets as an entirety, if the surviving, resulting or transferee entity, as the case may be, (a) shall be incorporated, organized or formed and existing under the laws of one of the States of the United States of America or any country which is a member of the Organisation for Economic Co-operation and Development (“OECD”), (b) assumes jointly with Guarantor (or alone if Guarantor is dissolved as a consequence of such transaction), if such corporation or other entity is not Guarantor, all of the obligations of Guarantor hereunder (unless such assumption occurs by operation of law, in which case no express assumption shall be required) and (c) is not, after such transaction, otherwise in default under any provisions hereof or the SPA.
