Dear Sam:

 

In recognition of your on-going contribution to Tetra Tech and your invaluable
management expertise in the leadership of the Company, the Board and executive
management believe it is critical that your services to the Company continue for
the foreseeable future. Accordingly, the Company is providing you with the
following benefits:

 

•                  Compensation. Your base compensation will increase from
$400,000 to $425,000 annually, effective immediately. Your next base salary
compensation review is scheduled for December 2006.

 

•                  Equity Award. You will receive an equity award not to exceed
20,000 shares of restricted stock to retain your service for a minimum two-year
period. As you know, awards of restricted stock will be made under the Company’s
2005 Equity Incentive Plan, as approved by the Board of Directors today.
However, such Plan is subject to stockholder approval at the Annual Meeting of
Stockholders scheduled for March 6, 2005 and no awards under the Plan will be
made until such approval is obtained. This award does not preclude granting of
options as part of the ‘06 option grant program.

 

Please indicate your agreement with and acceptance of the terms of this letter
by signing a copy in the space provided below and returning it to me at your
earliest convenience.
