14.3.4         the Seller shall not from Completion take any action or otherwise do anything in relation to the Business Contracts without the Buyer’s prior written consent save in respect of any Business Contracts the performance of which has been completed in part by the Seller prior to the Completion and the action or deed solely relates to such partial performance and without effect or import to any other part of the Business Contract or its performance by the Buyer;

14.3.5         unless and until any such Business Contract is assigned or novated, the Seller shall (so far as it lawfully may) give all such reasonable assistance as the Buyer may reasonably require (at the Seller’s cost) to enable the Buyer to enforce its rights under such Business Contract and (without limitation) shall, on prior written request, provide access to all relevant books, documents and other information in relation to such Business Contract as the Buyer may require from time to time.

14.4.3         The Termination Notice shall specify the name and address of the Agent upon whom it is to be served, details of the Agency Contract to be terminated and the number of days or months from the date of the Termination Notice after which the Agency Contract will terminate, which shall be not less than any Termination Notice period specified in the Agency Contract or if greater or none is so specified the Termination Notice period that applies under the governing law of the Agency Contract or such other notice period as the Buyer and the Seller may agree.

32

14.4.7         the obligations of the Buyer and the Seller pursuant to clause 14.3 shall cease in relation to any Agency Contract for which a Termination Notice is served upon expiry of such Termination Notice.

14.5            Nothing in this agreement shall be construed as an assignment or attempted assignment if such assignment or attempted assignment would constitute a breach of such Business Contract.

14.6            Nothing in this clause 14 or elsewhere in this agreement shall have the effect of making the Buyer liable in any way under any guarantees or warranties given by the Seller to any Customer in relation to goods sold or services rendered by the Seller before the Effective Time, the liability for which shall remain absolutely with the Seller.

14.7            The Seller shall indemnify and hold the Buyer harmless from and against all Demands of whatsoever nature relating to and payable in respect of the Business or Assets which are attributable to the period up to and including the Effective Time, including any act or omission on the part of the Seller in relation to the Business Contracts or any defects in, or alleged defects in, goods supplied or services provided prior to the Effective Time, and in particular any claim under any warranty or under the Sale of Goods Act 1979 or the Supply of Goods Act 1994.
