		(b) If suit is brought against the Customer alleging that Product infringes any United States patent other than by reason of use of any Customer Intellectual Property in producing Product in accordance with the Customer specifications, Bel shall, at its own expense, defend and control such suit and pay any award of damages against the Customer, provided the Customer notifies Bel promptly of the filing of such suit and gives Bel complete control of the same. Bel shall not be liable in any respect except as aforesaid, including without limitation, for any claim of infringement settled by the Customer without Bel’s prior written consent. If a final injunction shall be obtained against the Customer by reason of such infringement, or if in Bel’s opinion, upon advice of legal counsel, a Product is likely to become the subject of a claim of such infringement, Bel may, at its option and at its expense (i) procure for the Customer the right to continue using the Product; or, (ii) replace or modify the same so that it becomes non-infringing.

18.2		(a) Bel will indemnify, save harmless and defend the Customer, its affiliates and customers from any and all claims, actions, losses, expenses, costs or damages (including, reasonable legal fees and expenses) (collectively, “Losses”) which the Customer, its affiliates and customers may suffer or incur as a result of (i) any negligent act or omission or willful misconduct of Bel, its employees, representatives, agents or subcontractors relating to this Agreement; or (ii) any breach of Bel’s representations, warranties or obligations under this Agreement.
		(b) Bel will have no liability pursuant to Section 18.2(a) to the extent the Losses arise solely and directly due to (i) the use of goods by the Customer in a manner for which they were not designed (unless such use was agreed to in advance by Bel); or (ii) the negligence of the Customer, its employees, agents or subcontractors.
		(c) Customer shall promptly notify Bel of any claim for which the Customer believes it is entitled to indemnification (provided that the Customer’s failure to provide such notice will relieve Bel of its indemnification obligations only if and to the extent that such failure actually prejudices Bel’s ability to defend the claim.)

developments. The Customer may participate in any such proceedings, at its expense. The Customer will permit Bel to control, in a manner not adverse to Customer, the defense of any such claim; provided that any and all settlements or consents to judgment related to matters described in this Section 18.2 shall be subject to the prior written approval of Bel’s President or General Counsel with respect to Bel and the prior written approval of the Customer’s President with respect to the Customer.
