Dear colleague:

As a leader of Trane, you play a significant role in our success. One way we recognize your contribution is through special leadership compensation. Together with Ingersoll Rand, we’ve worked to ensure that you continue to receive appropriate value from this compensation as we move forward with the acquisition. Today, I’m writing to explain any impact that the planned sale of Trane to Ingersoll Rand will have to your Annual Incentive Plan (AIP), stock options, restricted stock units (RSUs) and Long-Term Incentive Plan (LTIP).


2007 – There is no change to the 2007 Annual Incentive Plan award. As usual, AIP awards will be based on business and individual results and payable in February 2008 under the terms and conditions of the current plan.

2008 – The 2008 AIP awards will be determined under the current plan on a prorated basis through the closing date, the day on which Trane and Ingersoll Rand become one company. The award will be paid at target and distributed shortly after the closing date.


What you can do right now

As usual, any vested options you have today may be exercised now or before the closing date as long as you are not restricted from doing so under applicable laws or company policy. You may also continue to hold your vested options.

Before the closing date, you will be given the opportunity to decide what you want to do with your vested and unvested nonqualified options after the closing date. The following section explains your choices.

What will occur as of the closing date

All of your unvested Trane stock options will vest and become immediately exercisable. Your choices include:


  o Cashing out some or all of your nonqualified stock options at approximately their fair market value on the closing date. As soon as possible after the closing date, you will receive the cash proceeds.


  o Converting some or all of your Trane stock options to Ingersoll Rand stock options with the same terms and conditions as your existing Trane options. The conversion will be done in a way that retains the approximate value of your Trane options as of the closing date. Such shares are


subject to the same terms and conditions as the existing Trane options, will be immediately exercisable and will be issued as soon as possible. In general, incentive stock options (ISOs) and, for option holders in France, tax-qualified French options will be automatically converted to Ingersoll Rand stock to protect their tax-favored status, with no cash-out choice.


  o A combination of cash-out and conversion of your nonqualified stock options, as described above.

Making your choice: How you proceed is up to you. You will receive an option-election form during the same timeframe as Trane distributes its proxy to shareowners to ask for approval of the acquisition. You will be required to complete and return the election form shortly before the closing date. We will provide you with more detail on the option-election process, along with examples of how the option conversion and cash-out will work in the near future.

If you have WABCO stock options

Your WABCO stock options are not affected by Ingersoll Rand’s acquisition of Trane.

However, if your employment with Trane is involuntarily terminated without cause after the closing, your unvested WABCO options will vest and become immediately exercisable. In that case, you will have the same time period to exercise your WABCO options as you currently have for your corresponding Trane option grant (i.e., 90 days unless you are retirement-eligible).


All of your unvested Trane restricted stock units (RSUs), and any accrued, but unpaid, dividend equivalents will vest immediately upon the closing date. You will receive $36.50 in cash and .23 shares of Ingersoll Rand (NYSE: IR) stock for every Trane RSU you hold. Any accrued dividend equivalents will be paid to you in cash.


2005-2007 award: As usual, the 2005-2007 award will be based on business results. Your award will be payable in February 2008 under the terms and conditions of the current plan.

Future LTIP cycles: The other in-progress LTIP cycles will each be prorated and paid out at target. The awards will be calculated on each cycle’s LTIP target and prorated for the number of months in the cycle prior to the closing date.

Awards will be paid at target and distributed shortly after the closing date.


Ingersoll Rand will evaluate the compensation provided to Trane employees and make a determination of the compensation to be offered after the closing date. However, for 12 months following the closing date, Ingersoll Rand will provide to active employees a base salary, benefits and long- and short-term incentive compensation opportunity that, in the aggregate, are no less favorable than those provided immediately prior to the closing date.

We want to thank you for your contributions and your continued leadership during this time of transition for the company. We’re working hard with Ingersoll Rand to get answers to compensation and other questions and will keep you updated as decisions are made. If you have any questions, please contact Noreen Farrell, vice president of Global Compensation, at 732-980-6060.
