CUSIP NO. 51476K 10 3

The following constitutes Amendment No. 4 to the Schedule 13D filed by the undersigned (“Amendment No. 4”). This Amendment No. 4 amends the Schedule 13D as specifically set forth herein.

Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

The Shares deemed to be beneficially owned by Gilead Capital were purchased with working capital in open market purchases, except as otherwise noted, as set forth in Schedule A, which is incorporated by reference herein. The aggregate purchase price of the 525,361 Shares deemed to be beneficially owned by Gilead Capital is approximately $19,849,430, including brokerage commissions.

Item 4.

Purpose of Transaction.

Item

4 is hereby amended to add the following:

On September 6, 2017, the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”), with Fortive Corporation, a Delaware corporation (“Parent”), and Fern Merger Sub Inc., a Delaware corporation and an indirect wholly owned subsidiary of Parent (“Sub”). Pursuant to the Merger Agreement, on the terms and subject to the conditions set forth in the Merger Agreement, as promptly as reasonably practicable (and, in any event, no later than September 20, 2017), Sub will commence a tender offer (the “Offer”) to purchase any and all of the outstanding shares of common stock, par value $0.10 per share, of the Issuer (“Company Common Stock”), at a price per share of Company Common Stock of $67.25 (such amount, or any other amount per share paid pursuant to the Offer and the Merger Agreement, the “Offer Price”), subject to any required withholding of taxes, net to the seller thereof in cash, without interest, on the terms and subject to the conditions and limitations set forth in the Merger Agreement. The Merger Agreement also provides that, following the time Sub irrevocably accepts for payment all shares of Company Common Stock that Sub became obligated to purchase pursuant to the Offer, upon the terms and subject to the conditions set forth in the Merger Agreement, Sub will be merged with and into the Issuer (the “Merger”) in accordance with Delaware law, with the Issuer continuing as the surviving corporation. As a result of the Merger, the Issuer will become a wholly owned subsidiary of Parent.

Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than (i) shares held by stockholders who have properly exercised appraisal rights under Delaware law and (ii) shares held in the treasury of the Issuer or by Parent, Sub or any of their respective wholly owned subsidiaries) will automatically be converted into the right to receive the Offer Price in cash, subject to any required withholding of taxes, without interest.

A more complete description of the Merger Agreement and the conditions to the Offer are set forth in the Issuer’s Current Report on Form 8-K filed with the SEC on September 6, 2017 (the “Issuer 8-K”). Such description of the Merger Agreement is incorporated herein by reference and is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached as Exhibit 2.1 to the Issuer 8-K and is also incorporated herein by reference.

Concurrently with the execution and delivery of the Merger Agreement, the Reporting Persons entered into a tender and support agreement (the “Support Agreement”) with Parent and Sub pursuant to which it agreed to tender all of the Shares in the Offer, subject to certain exceptions. The Support Agreement automatically terminates, among other items, upon the termination of the Merger Agreement or upon a Change of Company Recommendation (as such term is defined in the Merger Agreement). The foregoing description of the Support Agreement is qualified in its entirety by the full text of the Support Agreement, the form of which is attached hereto as Exhibit 99.2 and is incorporated herein by reference.

Item 5.

Interest in Securities of the Issuer.

Items 5(a)-(c) are hereby amended and restated to read as follows:
