PRELIMINARY STATEMENTS

The Company, as seller, Beckman, as servicer, the Purchasers and the Administrative Agent are parties to that certain Receivables Purchase Agreement dated as of October 31, 2007 (as amended, restated, supplemented or otherwise modified prior to the date hereof, the “Purchase Agreement”).

Beckman, as originator, and the Company, as buyer, are parties to that certain Receivables Sale Agreement dated as of October 31, 2007 (as amended, restated, supplemented or otherwise modified prior to the date hereof, the “Sale Agreement”).

On February 6, 2011, Beckman entered into a definitive Agreement and Plan of Merger (the “Merger Agreement”) with Danaher Corporation (“Danaher”) and Djanet Acquisition Corp. (the “Purchaser”) pursuant to which Danaher, through the Purchaser, will commence an offer (the “Tender Offer”) to acquire all of the outstanding shares of Beckman’s common stock. The Merger Agreement also provides that, following consummation of the Tender Offer and satisfaction of certain conditions, the Purchaser will be merged with and into Beckman (the “Merger”), with Beckman surviving as a wholly-owned indirect subsidiary of Danaher.

The parties enter into this Waiver to set forth their agreement in respect of certain consequences arising under the Purchase Agreement and the Sale Agreement by reason of the execution and delivery of the Merger Agreement and the transactions contemplated therein (collectively, the “Merger Transaction”).

NOW, THEREFORE, in consideration of the premises set forth above, the terms and conditions contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Waiver in respect of Sale Agreement. Effective as of the date hereof, subject to the satisfaction of the conditions precedent set forth in Section 3, the Company and Beckman agree, with the consent of the parties to the Purchase Agreement, that:

1.1 Any “Termination Event” that shall have occurred under Section 5.1(d) of the Sale Agreement by reason of the Merger Transaction is hereby waived.

1.2 The Termination Date under the Sale Agreement shall not be deemed to have occurred by reason of the Merger Transaction.

1.3 To the extent the sales or contributions under the Sale Agreement by Beckman to the Company of Receivables shall have ceased or been subject to delay by reason of the Merger Transaction, such sales and contributions shall forthwith recommence and continue until the occurrence of the Termination Date for any reason other than any aspect of the Merger Transaction.

1.4 Any Termination Event that shall have occurred by reason of any failure to provide notice as required under the terms of the Sale Agreement in respect of the Merger Transaction prior to the date hereof is hereby waived.

2. Waiver in respect of Purchase Agreement. Effective as of the date hereof, subject to the satisfaction of the conditions precedent set forth in Section 3, the parties to the Purchase Agreement agree that:

2.1 Any Amortization Event that shall have occurred under Section 9.1(j) of the Purchase Agreement (and any corresponding Servicer Default that shall have occurred under Section 8.7(a) of the Purchase Agreement) by reason of the execution and delivery of the Merger Agreement constituting a “Change of Control” under clause (iii) of the definition thereof is hereby waived.

2.2 It is acknowledged that the Purchasers and the Administrative Agent have not had adequate time to review and consider the implications that the Merger Transaction may have directly or indirectly for the transactions contemplated in the Transaction Documents.

No failure or delay on the part of the Purchasers or the Administrative Agent in exercising any such power, right or remedy shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or remedy preclude any other further exercise thereof or the exercise of any other power, right or remedy. In the event the Purchasers and the Administrative Agent shall in their sole discretion at any time after the date hereof elect to waive any such power, right or remedy, such waiver shall be effected by a separate written instrument executed by the Purchasers and the Administrative Agent.
