ITEM 5. OTHER EVENTS.

                  On October 26, 1999, Lennox International Inc. ("Lennox")
entered into an Agreement and Plan of Merger (the "Merger Agreement") with
Service Experts, Inc. ("SVE") and LII Acquisition Corporation, a wholly-owned
subsidiary of Lennox ("Merger Sub"), pursuant to which Merger Sub will be merged
with and into SVE (the "Merger") and SVE will become a wholly-owned subsidiary
of Lennox. As a result of the Merger, each outstanding share of common stock of
SVE will be converted into 0.67 of a share of common stock of Lennox.

                  In connection with the execution of the Merger Agreement,
Lennox and SVE entered into a stock option agreement pursuant to which SVE
granted to Lennox an option, exercisable in certain circumstances described
therein, to purchase a number of shares of SVE's common stock equal to
approximately 19.9% of the number of outstanding shares of common stock of SVE.

                  A copy of the Merger Agreement is attached hereto as Exhibit
2.1 and a copy of the stock option agreement entered into in connection with the
Merger Agreement is attached hereto as Exhibit 2.2. The foregoing description of
the Merger Agreement and stock option agreement is qualified in its entirety by
reference to the full text of such agreements, each of which is incorporated
herein by reference. A copy of the press release of Lennox issued with respect
to the Merger is included as Exhibit 99.1 and incorporated herein by reference.
