Dear Gary:

We would like to take this opportunity to let you know how pleased British Pacific Properties Corporation is with the Carbon Monoxide and Variable Frequency Drive systems that your company installed as British Pacific Centre last year.

Immediately, we recognized a savings of approximately $1,300 per month of utility costs due to the CO System alone. These savings are resulting in a 1 year payback, even prior to applying the Utility Incentive.

We highly recommend the installation of the Carbon Monoxide and Variable Frequency Drive systems to other property managers and building owners due to their high efficiency and effectiveness, as well as their quick return on investment.

thanks again and we certainly appreciate doing business with a professional company such as yours.

Yours very truly,

BRITISH PACIFIC PROPERTIES CORPORATION
