EXHIBIT 99.1


CONSOLIDATED QUARTERLY RESULTS

In December 1999, the Staff of the Securities and Exchange Commission issued SAB
No. 101 "Revenue Recognition," which provides additional guidance in applying
generally accepted accounting principles for revenue recognition in financial
statements. The Company adopted SAB No. 101 in the fourth quarter of 2000,
however, as required by SAB No. 101, the impact of adoption was retroactively
recorded as of January 1, 2000. This exhibit presents the Company's quarterly
consolidated income statements both as previously reported and with the impact
of SAB No. 101.

The Company's interpretation of the requirements of SAB No. 101 resulted in
changes to the Company's accounting policies for revenue recognition on sales of
its termite baiting contracts. Prior to the adoption of SAB No. 101, the Company
recognized approximately 80% of the termite baiting revenue at the time of the
sale and installation of the baiting station, while the remaining 20% of the
revenue was recognized over the life of the contract as follow-up inspections of
the stations were performed. As a result of SAB No. 101, the Company's policy is
to recognize revenue over the life of the contract. In addition, sales
commissions and other direct contract acquisition costs are deferred and
amortized on a straight-line basis over the life of the contract.
