Upon any default by MNL, Numonyx B.V. or MTAP in the performance of the Guaranty Obligations, Beneficiary may immediately proceed against Guarantor hereunder without bringing action against or joining MNL, Numonyx B.V. or MTAP.

Section 2.4Defenses to Enforcement. It will not be a defense to the enforcement of this Guaranty that the execution and delivery of the Joint Venture Agreement by MNL, Numonyx B.V. or MTAP was unauthorized or otherwise invalid, or that any of the obligations of MNL, Numonyx B.V. or MTAP thereunder are otherwise unenforceable. Guarantor intends this Guaranty to apply in respect of the obligations of MNL, Numonyx B.V. and MTAP that would arise under the Joint Venture Agreement if all of the provisions thereof were enforceable against MNL, Numonyx B.V. and MTAP in accordance with their terms.

Section 2.5Action with Respect to the Guaranty Obligations. Guarantor agrees that the obligations of Guarantor hereunder are unconditional and irrevocable under the circumstances set forth in the Joint Venture Agreement, subject to the terms and conditions of this Guaranty, and will not be impaired, released, terminated, discharged or otherwise affected except by performance thereof in full. Without limiting the generality of the foregoing, such obligations of Guarantor will not be affected by any of the following:

(a)any modification or amendment of, or addition or supplement to, the Joint Venture Agreement agreed to in writing by Guarantor or MNL, Numonyx B.V. or MTAP unless also agreed to in writing by Beneficiary;

(b)any exercise or non-exercise of any right, power or remedy under, or in respect of, the Joint Venture Agreement;

(c)any waiver, consent, release, extension, indulgence or other action, inaction or omission under, or in respect of, the Joint Venture Agreement, unless also agreed to in writing by Beneficiary;

(d)any insolvency, bankruptcy or similar proceeding involving or affecting MNL, Numonyx B.V. or MTAP or any liquidation or dissolution of MNL, Numonyx B.V. or MTAP; or

(e)any failure of MNL, Numonyx B.V. and MTAP to comply with any of the terms or conditions of the Joint Venture Agreement.

Section 2.6Delays; Waivers. No delay by Beneficiary in exercising any right, power or privilege under this Guaranty or failure to exercise the same will constitute a waiver or otherwise affect such right, power or privilege, nor will any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. No notice to or demand on Guarantor will be deemed to be a waiver of (a) any obligation of MNL, Numonyx B.V. or MTAP or (b) any right of Beneficiary to take any further action or exercise any rights under this Guaranty or the Joint Venture Agreement.

Section 2.7Defenses. Notwithstanding the foregoing, nothing in this Guaranty will restrict Guarantor from raising the defense of prior payment or performance by MNL, Numonyx B.V. or MTAP of the obligations which Guarantor may be called upon to pay or perform under this Guaranty or the defense (other than a defense referred to in Section 2.4) that there is no obligation on the part of MNL, Numonyx B.V. or MTAP with respect to the matter claimed to be in default under the Joint Venture Agreement.
