        MEMORANDUM


Date:      April 26, 2005                          Job No.:

To:        TKC RESTRICTED STOCK HOLDER             Project:   TKC/Stantec Merger

From:      Eric Nielsen

Re:        Restricted Stock Treatment
--------------------------------------------------------------------------------

TREATMENT OF TKC RESTRICTED STOCK

We have summarized below the treatment of outstanding restricted stock 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 restricted stock will continue in effect in accordance with their
terms without modification.

This summary does not address the tax treatment resulting from restricted stock
transactions. 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.

If you hold RESTRICTED STOCK that has vested and is no longer subject to a risk
of forfeiture, your shares will be exchanged in the merger on the same terms as
all other outstanding shares of our common stock.

If you hold restricted stock that is not vested at the effective time of the
merger, Stantec common shares will be substituted for the shares of unvested
restricted common stock of TKC held by you. The substituted shares will continue
to be subject to the vesting provisions and risk of forfeiture provisions in
your restricted stock agreement. Each of your shares of TKC unvested restricted
common stock will be substituted with that number of shares of common stock of
Stantec that the holder would have received in the merger if such holder had
elected to receive all Stantec.
