Dear Trane leaders,

Moments ago, we issued a news release announcing that our board has set Thursday, June 5, 2008, as the meeting date for our shareowners to vote on the proposed acquisition by Ingersoll Rand.

We have done a lot of work to obtain the required regulatory approvals for this transaction and just received word that the Securities and Exchange Commission declared Ingersoll Rand’s Form S-4 effective. This allows us to set the meeting date, which has to be at least 20 business days from the date we begin mailing the proxy statement and prospectus to our shareowners.

We will now start mailing the proxy statement and prospectus to all eligible Trane shareowners. If our shareowners approve the sale on June 5, all conditions will have been satisfied and we expect to complete the acquisition on June 5 or as soon as administratively practical after that.

You will soon receive more information on what is planned for the first day after closing, expected to be June 6, and on what employees need to know moving forward. In the meantime, please continue to help your team stay focused on our business and the things we need to do to complete the sale and make the future of the new Ingersoll Rand successful.

Thanks,
