(b) in respect of the reduction of the Purchase Price pursuant to Clause 4.1(b):

(i) the date the Company’s interim results for the six months ending 30 September 2010 are announced; or

4.5 If any payment is due to the Buyers pursuant to Clause 4.3 before the First Deferred Payment or the Second Deferred Payment is due, then the amount payable pursuant to Clause 4.3 shall be settled by a pound (£) for pound (£) or dollar ($US) for dollar ($US) set off of the amount due against the First Deferred Payment or the Second Deferred Payment (as applicable) (such set off to be pro rated between each of the Buyers in proportion to their obligation to pay the Purchase Price), without prejudice to the Buyers’ right to claim more if the amount payable pursuant to Clause 4.3 exceeds the amount of the First Deferred Payment and/or the Second Deferred Payment.

4.6 The Seller undertakes to:

(a) to keep the Buyers regularly and promptly informed of the progress of the UK Legal Proceedings and the US Legal Proceedings (including all  settlement negotiations and any other material developments) and notify the Buyers as soon as possible if any order, award or judgement is made or any settlement negotiations commence or settlement agreement is entered into in relation to such proceedings and provide the Buyers with copies of any such order, award or judgement or documentation relating to any settlement negotiations or settlement agreement; and
