This Amendment No. 4 (this “Amendment”) to the Tender Offer Statement on Schedule TO (the “Schedule TO”) amends and supplements the Schedule TO filed by (i) Daphne Acquisition Corporation, a Delaware corporation (“Purchaser”), and an indirect wholly-owned subsidiary of Danaher Corporation, a Delaware corporation (“Parent”), and (ii) Parent, for all of the outstanding shares of common stock, par value $0.01 per share (the “Shares”) of IRIS International, Inc., a Delaware corporation (the “Company”), at a price of $19.50 per Share net to the seller in cash without interest and less any applicable withholding taxes, if any, upon the terms and conditions set forth in the offer to purchase dated September 20, 2012 (the “Offer to Purchase”), a copy of which is attached as Exhibit (a)(1)(A), and in the related letter of transmittal (the “Letter of Transmittal”), a copy of which is attached as Exhibit (a)(1)(B), which, together with any amendments or supplements thereto, collectively constitute the Offer.

All the information set forth in the Offer to Purchase is incorporated by reference herein in response to Items 1 through 9 and Item 11 in this Schedule TO, and is supplemented by the information specifically provided in this Schedule TO.

This Amendment No. 4 is being filed to amend and supplement Item 11 as reflected below. Capitalized terms used and not otherwise defined in this Amendment shall have the meanings assigned to such terms in the Offer to Purchase or in the Schedule TO.

Item 11

(a) Agreements, Regulatory Requirements and Legal Proceedings. Item 11(a) of the Schedule TO is hereby amended and supplemented as follows:

The information set forth in Section 16—“Certain Legal Matters; Regulatory Approvals” of the Offer to Purchase is hereby amended and supplemented by inserting the following paragraph as the fifth paragraph of the subsection captioned “General”:

“On October 12, 2012, a putative class action lawsuit captioned Caro v. César M. García et al., Civil Action No. EDCV12-1755, was filed in the United States District Court, Central District of California, Western Division, Los Angeles. The complaint names as defendants the Company, the Board of Directors, Parent and Purchaser. The plaintiff alleges that the Board of Directors breached its fiduciary duties to the Company’s stockholders in connection with the Offer and the Merger, and further alleges that Parent and Purchaser aided and abetted those alleged breaches of fiduciary duty. The complaint also alleges the Board of Directors violated provisions of the Securities Exchange Act of 1934, including the Williams Act, by omitting material facts from the Schedule 14D-9 Recommendation Statement the Company filed with the Securities and Exchange Commission on September 24, 2012, in connection with the Offer and the Merger. Among other things, the complaint alleges that the Offer and the Merger involve an unfair price and an inadequate sale process and that the Company has failed to make adequate disclosures about the background of the Offer and the Merger and the work performed by Citi as the Company’s financial advisor with respect to the Offer and the Merger. The complaint seeks an order declaring the Recommendation Statement to be materially misleading, enjoining the Offer and the Merger, directing defendants to account to plaintiff and the members of the class for all damages caused by them and to account for all profits and any special benefits obtained as a result of their alleged breaches of fiduciary duties, and awarding attorneys’ fees and other costs, in addition to granting other and further equitable relief. The Company and Parent believe the plaintiff’s allegations lack merit and intend to contest them vigorously.”


After due inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
