LII Proxy Statement: Your Vote Counts

             The LII annual report, 10-K, proxy statement and proxy card are being mailed to LII shareholders, in connection with solicitation of proxies by the LII board of directors for the LII annual meeting on April 15, 2005. If you are a LII shareholder as of the close of business on February 18, 2005, you are eligible to vote on both proxy proposals:

1.

Election of Directors: To help ensure continuity of strong leadership for LII, there are five nominees for election for a term expiring at the 2008 Annual Meeting of Stockholders. The proxy statement provides detailed information about each nominee.

2.

Approval of the LII Amended and Restated 1998 Incentive Plan: The board of directors believes it is important to have equity-based incentives available to attract and retain qualified directors, employees and independent contractors who are essential to the success of LII and it subsidiaries, and that it is important to link the interests and efforts of such persons to the long-term interest of LII shareholders. The proxy statement provides detailed information about the proposed amended and restated plan.

             For proposal one, the board of directors recommends a vote “for” each of the five nominees. For proposal two, the board of directors recommends a vote “for” approval of the LII Amended and Restated 1998 Incentive Plan. If you are eligible to vote but do not receive your copy of the proxy statement and proxy card by Monday, April 4, contact your broker or if you hold registered shares, call Mellon Investor Services at 1-800-797-5603.
