           MEMORANDUM


DATE:      April 29, 2005                          JOB NO.:
TO:        RECIPIENT                               PROJECT:   TKC/Stantec Merger
FROM:      Eric Nielsen

RE:        Stock Options Treatment
- --------------------------------------------------------------------------------

TREATMENT OF TKC EMPLOYEE STOCK OPTIONS

We have summarized below the treatment of outstanding employee stock options
under The Keith Companies' (TKC) merger agreement with Stantec. The following
summary assumes our merger is actually consummated, which is not expected to
occur until the third quarter 2005. Be advised that the merger is subject to
various conditions, including approval by TKC's shareholders, and if the merger
is not completed, all employee stock options will, unless exercised, continue in
effect in accordance with their terms without modification.

This summary does not address the tax treatment resulting from the exercise or
tender of employee stock options. You are directed to the TKC's filing on Form
S-8 with the Securities and Exchange Commission for a general discussion with
respect to tax matters. However, we strongly urge you to consult your own tax
advisor.

        TERMINATION OF OPTIONS

All outstanding employee stock options will terminate at the effective time of
the merger. Consequently, in order to receive the value of any excess of the
merger consideration over the exercise price of your vested or unvested options,
please see below for a discussion of the treatment of vested and unvested
options.

        VESTED OPTIONS

In order to receive the value of any excess of the merger consideration over the
exercise price of the vested options you hold, you must EXERCISE THE VESTED
OPTIONS prior to the effective time of the merger. We will provide you notice of
when we anticipate the effective time to occur about 20 business days in advance
of the effective time so that you will have sufficient time to exercise vested
options. In addition, we expect to provide a mechanism whereby you will be able
to condition your exercise on the consummation of the merger. You may exercise
your option by paying the exercise price in cash or on a "cashless" basis by
surrendering some of your "in the money" options in lieu of the cash exercise
price. You will receive shares of common stock of TKC when you exercise your
vested options. This common stock will be exchanged in the merger on the same
terms as all other outstanding shares of our common stock.






        UNVESTED OPTIONS

Options which are "unvested" at the effective time of the merger may not be
exercised by you. About 20 business days prior to the effective time, we intend
to make an offer to purchase your unvested options for a cash purchase price
equal to the difference between the value of the merger consideration and the
exercise price of the option. We will make this offer pursuant to a separate
document which will contain instructions on how you may accept the offer. Any
offer to purchase that we make will be conditioned on the merger actually
occurring. Consequently, in order to receive the value of any excess of the
merger consideration over the exercise price of the unvested options you hold,
you must SUBMIT YOUR UNVESTED OPTIONS for purchase when we offer to purchase
them.
