3. Maximum Amount Guarantee and Undertaking to Reimburse, contract for the benefit of third parties

3.1 The Guarantor hereby irrevocably and unconditionally guarantees by way of an independent guarantee (Garantie) to each of the Beneficiaries up to a maximum aggregate amount of:

the payment of all principal, interest (including default interest, if any), costs, expenses or other amount which are due and payable by any Local Borrower under any Agreement (for the avoidance of doubt without limitation to the relevant amounts specified in Schedule 1 hereto) from time to time in the

currency and at the place provided in that agreement or, at the option of either of the beneficiaries, in euros, at its stated or accelerated maturity irrespective of the factual or legal circumstances and motives by reason of which any local borrower may fail to pay such amount.

3.2 Any Beneficiary shall be entitled to demand direct payment hereunder from the Guarantor.

With regard to Beneficiaries which are Affiliates of the Beneficiary 1, this Maximum Amount Guarantee constitutes a contract for the benefit of third parties according to Section 328 of the German Civil Code. Irrespective of the above, the Beneficiary 1 may claim payment of the guaranteed amounts on behalf of any other Beneficiary for the purpose of forwarding the received amounts to the respective Beneficiary.

3.3 The Guarantor shall effect payment under this Maximum Amount Guarantee within five days after receipt of a written demand of the respective Beneficiary which shall be accompanied by a confirmation by the relevant Beneficiary that the amount claimed from the Guarantor equals the amount which any of the Local Borrowers has not paid when due. The Guarantor hereby waives its right under any jurisdiction applicable to it to payment in any other currency than Euro.

3.4 This Maximum Amount Guarantee and the undertaking to reimburse (promise to pay) under Clauses 3.1 and 3.2 above constitute the Guarantor's primary and independent obligation to make payment to the Beneficiaries in accordance with the terms hereof, under any and all circumstances, regardless of the validity, legality or enforceability of the obligations of any Local Borrower irrespective of all objections, exceptions or defenses from any Local Borrower under any Agreement or from any other person.

(a)

this Maximum Amount Guarantee does not constitute a guarantee upon first demand and nothing in this Maximum Amount Guarantee, in particular receipt of the written demand referred to in Clause 3.3 above, shall preclude any rights or defenses (Einden und Objections) the Guarantor may have (in its capacity as Guarantor only) with respect to any payment requested by any of the Beneficiary under this Maximum Amount Guarantee; other

(b)

an amendment to Schedule 1 pursuant to, and in accordance with, Clause 2 above shall not be construed as an increase of the maximum aggregate amount referred to in Clause 3.1 above.

The Beneficiaries (including in their capacity as Local Lenders) are not obliged first to claim payment from, to take any legal action against, or enforce any claims or security, if any, granted by any Local Borrower or any other person before making demand from the Guarantor hereunder.

The obligations of the Guarantor hereunder shall not be contingent upon the legal relationship between the Beneficiaries (or any of them) on the one hand and the Local Borrowers on the other hand and accordingly shall without limitation be independent of:

(d)

any absence of any authorization or any factual or legal restriction or limitation existing or introduced in the country of the Local Borrower (including, but not limited to, force majeure or any event or action delaying or preventing any conversion or transfer of any amount to, or its receipt in, the agreed account);

ny agreement, including any extension of the term of payment and any rescheduling or restructuring of their indebtedness, whether or not the guarantor shall have given its consent thereto;

(G) the taking, existence, variation or release of any other collateral provided to the Beneficiaries (or any of them) for the obligations of the Guarantor or the Local Borrowers and the Beneficiaries' legal relationship with any provider of such other collateral;

(i) any right that a beneficiary may have to set-off the indebtedness against a counterclaim of the guarantor or any local borrower.

Payments made by the Guarantor to a Beneficiary pursuant to a judgment or order of a court or tribunal in a currency other than the currency owed according to Clause 3.1 above shall only constitute a discharge of the Guarantor's obligation hereunder to the extent that the respective Beneficiary, immediately after receipt of such payment in such other currency, would be able to purchase with the amount of the other currency so received the owed currency on a recognized foreign exchange market. If the amount so received in the currency owed in accordance with Clause 3.1 should be less than the amount due, then as a separate and independent obligation, which gives rise to a separate cause of action, the guarantor is obliged to pay the difference.

So long as any sum remains payable under any Agreement or this Maximum Amount Guarantee, the Guarantor undertakes not to assert or enforce any claim it may have against any Local Borrower by reason of the performance of the Guarantor's obligations hereunder whether on contractual grounds or on any other legal basis, until all amounts payable to the Beneficiary 1 or the Local Lenders under the Agreements and this Maximum Amount Guarantee have been fully and irrevocably received or recovered; any amount received or recovered by the Guarantor from a Local Borrower shall be held in trust for and immediately paid to the Beneficiary 1 on behalf of himself and the Local Lenders. The obligations of the Guarantor hereunder shall remain in force notwithstanding any dissolution or change in the structure or legal form of the Local Borrower or the Guarantor.

The obligations of the Guarantor hereunder are effective as of the date hereof and shall expire on the date on which all amounts expressed to be payable by the Guarantor and the Local Borrowers under the Agreements and this Maximum Amount Guarantee (respectively) have finally and irrevocably been paid or repaid in full to the beneficiaries.

The obligations of the Guarantor hereunder may be enforced against the Guarantor by each

Should any of the Beneficiaries become liable to return monies received in payment of indebtedness payable by the Guarantor or any Local Borrower under the Agreements or any other document (including, for the avoidance of doubt, this Maximum Amount Guarantee) as

a result of any bankruptcy, composition or similar proceedings affecting the Guarantor or a Local Borrower after expiry of this guarantee in accordance with Clause 8 (Expiry) above, the obligations of the Guarantor hereunder shall be reinstated and become effective again notwithstanding such expiration.

This Maximum Amount Guarantee and the undertaking to pay is in addition to and is not in any way prejudiced by any other guarantee or security now or subsequently held by any of the Beneficiaries.

12.1 All payments owed by the Guarantor shall be made in immediately available, freely convertible funds for value on the due date to such account with such bank as the relevant Beneficiary

specifies and only irrevocable crediting of such payment in full onto the account specified by the relevant Beneficiary shall discharge the Guarantor's payment obligation.

12.2 The Beneficiaries may set-off any obligation due from the Guarantor under this Maximum Amount Guarantee or any other agreement against any satisfiable obligation (whether due or not) owed by any of the Beneficiaries to the Guarantor, regardless of the place of payment, booking branch or currency of either obligation. If the obligations are in different currencies, the relevant Beneficiary may convert either obligation at a market rate of exchange in its usual course of business for the purpose of set-off.

(a) shall be paid without any deduction or withholding for or on account of tax (a “Tax Deduction”) unless a Tax Deduction is required by law. If a Tax Deduction is required by law to be made, the amount of the payment shall be increased to an amount which (after making any Tax Deduction) leaves an amount equal to the payment which would have been due if no Tax Deduction had been required . If in connection with payments under this Maximum Amount Guarantee any amounts on account of tax are imposed on the Beneficiary (other than by way of a Tax Deduction) in any jurisdiction (other than the jurisdiction where the relevant Beneficiary is tax resident or, if different , maintains a permanent establishment to which such payment is attributable), the Guarantor shall indemnify and hold harmless the relevant Beneficiary against any such tax; other

(b) are exclusive of any value added tax or similar charge (VAT). If VAT is chargeable, the Guarantor shall also and at the same time pay to the relevant Beneficiary an amount equal to the amount of the VAT.

16.2 If any term of this Maximum Amount Guarantee is or becomes illegal, void , invalid or unenforceable in any respect under any jurisdiction, that will not affect:

(b) the legality, validity or enforceability in that jurisdiction of any other term of the maximum amount guarantee; or the legality, validity or enforceability in other jurisdictions of that or any other term of the Maximum Amount Guarantee, without any party having to argue and prove the parties intent to uphold the agreement made pursuant to this Maximum Amount Guarantee even without the illegal, void, invalid or unenforceable provision(s), which intent shall be indisputable ). The illegal, void, invalid or unenforceable provision shall be deemed to be replaced by such legal, valid and enforceable provision that in legal and economic terms comes closest to what the parties intended or would have intended in accordance with the purpose of this Maximum Amount Guarantee if they had considered the point at the time of conclusion of this Maximum Amount Guarantee. The same shall apply mutatis mutandis to any gap in this Maximum Amount Guarantee.

16.4 No failure to exercise, nor any delay in exercising, on the part of the Agent or the other Finance Parties (or any of them), any right or remedy under this Maximum Amount Guarantee shall operate as a waiver thereof, nor shall any single or partial exercise of any right or remedy prevent any further or other exercise thereof or the exercise of any other right or remedy. The rights and remedies provided hereunder are cumulative and not exclusive of any rights or remedies provided by law.
