Greater than or equal to 2,50:1 170 140

Greater than or equal to 2,00:1 but less than 2,50:1 160 130

Greater than or equal to 1,50:1 but less than 2,00:1 150 120

Greater than or equal to 1,00:1 but less than 1,50:1 140 110

- 100 -

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.

3.5

For the avoidance of doubt,

(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

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.

5. Exclusion of defenses

95

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:

(a)
any amendment or any defect in any provision of any Agreement;
(b)
any absence or insufficiency of corporate resolutions relating to the indebtedness of any Local Borrower under any Agreement;
(c)
any inadequate representation of any local borrower;
(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);
(e)
any deferral or waiver of obligations or a consent or approval in favor of any local borrower;

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

6. Currency Indemnity

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.
