Item 39.~~02 Unregistered~~01. ~~Sales~~Financial ofStatements ~~Equity~~and ~~Securities~~Exhibits.

The information included in Item 1.01 regarding the Top-Up Option is incorporated into this Item 3.02 by reference. The Top-Up Option was issued without registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon the exemption from registration set forth in Section 4(2) of the Securities Act and Rule 506 of Regulation D promulgated thereunder.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

Effective June 20, 2015, the Board of Directors of the Company amended the Company’s Bylaws to opt out of the Control Share Acquisitions statute set forth in Article 14.1 of the Virginia Stock Corporation Act (the “Statute”). The Statute defines “control share acquisitions” as transactions causing the voting strength of any person acquiring beneficial ownership of shares of a Virginia public corporation to meet or exceed certain threshold percentages (20%, 33-1/3% or 50%) of the total votes entitled to be cast in the election of directors. Issuances directly from the corporation are excluded from such definition. Shares acquired in a control share acquisition have no voting rights unless (1) the voting rights are granted by a majority vote of all outstanding shares other than those held by the acquiring person or any officer or employee-director of the corporation, or (2) the Articles of Incorporation or Bylaws of the corporation provide that the Statute does not apply to acquisitions of the corporation's shares. The Statute would have permitted an acquiring person, under certain circumstances, to require the Company to call a special meeting of the shareholders to consider the grant of voting rights to the shares acquired in the control share acquisition.

The amendment is set forth in a new Article XV to the Company’s Bylaws. A copy of the amendment to the Company’s Bylaws is attached as Exhibit 3.2 to this report and is incorporated herein by reference.

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. Such forward-looking statements include the ability of the Company, Danaher and Purchaser to complete the transactions contemplated by the Merger Agreement, including the parties’ ability to satisfy the conditions to the consummation of the Offer and the other conditions set forth in the Merger Agreement and the possibility of any termination of the Merger Agreement. 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 Offer and the subsequent Merger; uncertainties as to how many of the Company’s stockholders will tender their Shares in the Offer; the risk that competing offers or acquisition proposals will be made; the possibility that various conditions to the consummation of the Offer or the 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 Offer or the Merger; the effects of disruption from the transactions contemplated by the Merger Agreement 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 Offer or the Merger 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.
