Dear Philip:

     On behalf of World Energy Solutions, Inc. ("World Energy"), I wish to
extend you an offer to join World Energy as Senior Vice President, Operations.

     You will be employed to serve on a full-time basis beginning on October 1,
2003 or on such other mutually agreeable date. You will be responsible for
running the operations of the company including, but not limited to managing the
marketing, finance, supply desk, IT, and human resource functions. These duties
may change from time to time, and may include such other duties as we may assign
to you.

     Your salary will be $10,000.00 per month for the period from October -
December 2003, and will be increased to $12,500.00 per month beginning January
2004. Such salary may be adjusted from time to time in accordance with normal
business practice and in our sole discretion.

     You may participate in any and all bonus and benefit programs that we
establish and make available to our employees from time to time, provided you
are eligible under (and subject to all provisions of) the plan documents
governing those programs. World Energy will pay 100% of your health care
premiums until such time when your salary increases to $12,500 per month. At
that time, World Energy will pay for a portion of your health care premiums
according to the formula in effect for all employees.

     You may be eligible for a maximum of 3 weeks of vacation per calendar year
to be taken at such times as may be approved by World Energy. The number of
vacation days for which you are eligible shall accrue at the rate of 1.25 days
per month that you are employed during such calendar year.

     Subject to the approval of our Board of Directors, you may be granted a
non-statutory stock option under our 2003 Stock Incentive Plan (the "Plan") for
the purchase of an aggregate of 1,250,000 shares of our common stock at a price
per share equal to the fair market value at the time of Board approval. The
option shall be subject to the terms of the Plan and our standard form option
agreement.

     You may be eligible to receive such future stock option grants as our Board
of Directors shall from time to time deem appropriate.

     You will be required to execute an Invention and Non-Disclosure Agreement
and a Non-Competition and Non-Solicitation Agreement in the forms attached as
Exhibit A and Exhibit B, respectively, prior to commencing employment.

     You represent that you are not bound by any employment contract,
restrictive covenant or other restriction preventing you from entering into
employment with or carrying out your responsibilities for us, or which is in any
way inconsistent with the terms of this letter.
