If and when the tender offer is commenced, (i) Danaher will file with the U.S. Securities and Exchange Commission (the “SEC”) a tender offer statement and (ii) Sutron Corporation will file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9. INVESTORS AND STOCKHOLDERS ARE URGED TO READ THE TENDER OFFER STATEMENT (INCLUDING AN OFFER TO PURCHASE, LETTER OF TRANSMITTAL AND RELATED TENDER OFFER DOCUMENTS) AND THE SOLICITATION/RECOMMENDATION STATEMENT ON SCHEDULE 14D-9 CAREFULLY WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION.

Forward-Looking Statements

Certain statements either contained in or incorporated by reference into this report, other than purely historical information, including estimates, projections and statements relating to the Company’s business plans, objectives and expected operating results, and the assumptions upon which those statements are based, are “forward-looking statements.” These forward-looking statements generally include statements that are predictive in nature and depend upon or refer to future events or conditions, and include words such as “believes,” “plans,” “anticipates,” “projects,” “estimates,” “expects,” “intends,” “strategy,” “future,” “opportunity,” “may,” “will,” “should,” “could,” “potential,” or similar expressions. The forward-looking statements contained in this report are based on current expectations and assumptions that are subject to risks and uncertainties which may cause actual results to differ materially from the forward-looking statements. Actual results may differ materially from current expectations because of risks associated with uncertainties as to the timing of the tender offer and potential merger; uncertainties as to how many of the Company’s stockholders will tender their shares in the tender offer; the risk that competing offers or acquisition proposals will be made; the possibility that various conditions to the consummation of the tender offer or proposed merger may not be satisfied or waived, including that a governmental entity may prohibit, delay or refuse to grant approval for the consummation of the merger; the effects of disruption from the tender offer on the Company’s business and the fact that the announcement and pendency of the transactions may make it more difficult to establish or maintain relationships with employees, suppliers and other business partners; the risk that stockholder litigation in connection with the tender offer may result in significant costs of defense, indemnification and liability; other uncertainties pertaining to the business of the Company, including those set forth in the Company’s filings with the SEC, especially in “Item 1A. Risk Factors” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 filed with the SEC on March 31, 2015. The reader is cautioned not to unduly rely on these forward-looking statements. The Company expressly disclaims any intent or obligation to update or revise publicly these forward-looking statements except as required by law.
