                  SAIC will perform the Services set forth in Exhibit A and

                  A.

                  This complete set of Services and Obligations is necessary for
                  the success of energy procurements. If either Party to this
                  agreement changes their resource contributions diminishing the
                  quality and level of effort of their Services or Obligations
                  to the extent that the other party must increase their
                  contribution or the customer requests the other party fulfill
                  Services or Obligations, then fees will be adjusted according
                  to Exhibit B or Exhibit C.

                  In addition, SAIC and World Energy agree that SAIC has
                  provided certain services to World Energy prior to the
                  Effective Date (as defined in Section 3 below). SAIC and World
                  Energy agree that this Agreement shall govern the obligations
                  of the parties hereto with respect to such services. Exhibit C
                  hereto specifically identifies all projects for which SAIC
                  provided services to World Energy, including those prior to
                  the Effective Date that are covered by this Agreement.

         2.       Place of Performance

                  Unless otherwise provided in this Agreement, SAIC may perform
                  the Services and World Energy may perform the Obligations in
                  whole or in part at either party's place of business, a
                  customer's place of business, and/or such other locations as
                  SAIC or World Energy may select.

         3.       Effective Date; Term

                  This Agreement shall be effective as of the date first above
                  written (the "Effective Date"), and shall continue in full
                  force and effect for a period of one year (the "Term") unless
                  such Term is otherwise extended in a written instrument signed
                  by both parties or the Agreement has been earlier terminated
                  in accordance with Section 10 hereof.

         4.       Payment Terms

                  (a)      World Energy will pay SAIC on the 25th day of the
                  month following the month in which World Energy has received
                  payment from a supplier in connection with the Services
                  performed by SAIC (each, a "Payment Date"). Supplier invoices
                  will be included with payments to SAIC to verify the date
                  supplier payments were received.

                  (b)      For Services performed after the Effective Date,
                           World Energy shall pay to SAIC for performing the
                           Services an amount computed by utilizing the Revenue
                           Sharing Schedule set forth in Exhibit B and according
                           to the parameters provided in Exhibit C. Estimated
                           total fees payable as a percentage of future revenue
                           to be received by World Energy in connection with
                           Services that SAIC provided to World Energy prior to
                           the Effective Date are listed in Exhibit C.

                  (c)      World Energy shall make payment to SAIC according to
                           the schedule and provisions of Exhibit B and the
                           estimated total fees for each auction as listed in
                           Exhibit C.

                  (d)      If payment is received from a supplier by World
                           Energy and World Energy's action or inaction results
                           in non-payment to SAIC on the appropriate Payment
                           Date, interest compounded at the rate of one percent
                           (1%) per month shall be charged on all amounts unpaid
                           and outstanding beginning 60 days after the
                           appropriate Payment Date. If World Energy's action or
                           inaction results in non-payment in whole to SAIC,
                           SAIC shall have the right, exercisable at SAIC's sole
                           discretion, in addition to its other rights and
                           remedies, to cease further performance of the
                           Services hereunder.

                  (e)      Notwithstanding anything to the contrary contained
                           herein, (i) World Energy shall be permitted to
                           withhold all or a portion of the fees to SAIC
                           otherwise payable hereunder in the event that World
                           Energy reasonably determines that the Services were
                           not performed in accordance with the standard set
                           forth in Section 11(a) below and (ii) in the event of
                           overpayment of fees by a supplier to World Energy,
                           resulting in full or partial credit to the supplier,
                           or in the event that a supplier requires World Energy
                           to repay, and World Energy repays, to such supplier
                           fees previously paid by such supplier to World
                           Energy, World Energy, at its option, may require
                           either that SAIC repay the corresponding portion of
                           the fee originally paid by World Energy to SAIC
                           within 10 business days after written notice thereof
                           from World Energy, or by deducting such amount from
                           one or more subsequent fees due to SAIC.

                  (f)      Notwithstanding anything to the contrary contained
                           herein, in no event shall World Energy be required to
                           pay to SAIC any fees which are received by World
                           Energy from a supplier under a renewal or extension
                           of an agreement between an energy customer listed on
                           Exhibit C or deals consummated subsequent to this
                           agreement and such supplier provided that SAIC has
                           not provided any Services related to securing such a
                           renewal or extension. In the case of a renewal or
                           extension of an agreement between an energy customer
                           and a supplier where such customer was referred or
                           introduced by SAIC and SAIC no longer provides

                  obligations, as SAIC may from time to time reasonably request

                  Energy acknowledges that delays in the provision of these
                  Obligations may result in delays in performing the Services.

         6.       Confidentiality

                  SAIC and World Energy recognize that during the term of this
                  Agreement, each will possess confidential, proprietary, or
                  trade secret information about the business of the other,
                  including marketing and product development plans, and agree
                  that the Confidentiality Agreement attached hereto as Exhibit
                  D shall govern the disclosure and use of such information,

                  Nothing in this Agreement or in the Confidentiality Agreement
                  referred to in this section shall be deemed to restrict or
                  prohibit World Energy from providing to others services that
                  are the same as or similar to the Services and Obligations
                  described herein. Nothing in this Agreement or in the
                  Confidentiality Agreement referred to in this section shall be
                  deemed to restrict or prohibit World Energy from entering into
                  arrangements with third parties (other than SAIC) to provide
                  services that are the same as or similar to the Services
                  described herein, or from otherwise dealing directly with
                  energy customers or suppliers without the assistance of SAIC.
                  In providing any such similar Obligations, services or
                  deliverables to any third party, World Energy shall keep

                  executed pursuant to this section, in accordance with the
                  requirements of such agreement.

                  In the event SAIC develops a product or service or works with
                  a third party offering a product or service that is in direct
                  competition with World Energy's business, this agreement will
                  be terminated and bound by the conditions contained in 10.

                  right, title and interest in and to, their respective,
                  confidential, proprietary, and trade secret information,
                  including all patents, copyrights, trade secrets, trademarks

                  granted by this Agreement or as a result of the Services
                  performed hereunder. To the extent the parties wish to grant
                  to the other rights or interests in such Intellectual
                  Property, separate license agreements on mutually acceptable
                  terms will be executed.

         9.       Taxes

                  of any and all taxes related to SAIC's income and any payments
                  received from World Energy hereunder), and shall comply with
                  all applicable treaties, laws, rules or regulations relating
                  thereto.

         10.      Termination

                  Either party may terminate this Agreement for any reason upon
                  30 days prior written notice to the other party. Except as
                  otherwise provided in Section 4 above or Exhibit B or Exhibit
                  C hereto, termination will not affect payment obligations
                  incurred under this Agreement for Services performed prior to
                  the expiration of such 30-day period (the date on which such
                  30-day period expires being referred to herein as the

                  which were entered into by SAIC in the course of performance
                  hereunder prior to the Expiration Date.

                  (a)      SAIC and World Energy warrant that the Services and
                  Obligations provided under this Agreement shall be performed

                            CONFIDENTIALITY AGREEMENT

         Agreement dated 21 SEPTEMBER 2004 the "Effective Date"), between World
Energy Solutions, Inc., a Delaware corporation ("World Energy"), and SCIENCE
APPLICATIONS INTERNATIONAL CORPORATION a Delaware corporation ("SAIC").

         1.       Background. World Energy and SAIC (the "parties") intend to
engage in discussions and negotiations concerning the possible establishment of
a business relationship between them. In the course of such discussions and
negotiations and in the course of any such business relationship, it is
anticipated that each party will disclose or deliver to the other party and to
the other party's directors, officers, employees, agents or advisors (including,
without limitation, attorneys, accountants, consultants, bankers, financial
advisors and members of advisory boards) (collectively, "Representatives")
certain of its trade secrets or confidential or proprietary information for the
purposes of enabling the other party to evaluate the feasibility of such
business relationship and to perform its obligations and exercise its rights
under any such business relationship that is agreed to between the parties (the
"Purposes"). The parties have entered into this Agreement in order to assure the
confidentiality of such trade secrets and confidential or proprietary
information in accordance with the terms of this Agreement. As used in this
Agreement, the party disclosing Proprietary Information (as defined below) is
referred to as the "Disclosing Party"; the party receiving such Proprietary
Information is referred to as the "Recipient".

         2.       Proprietary Information. As used in this Agreement, the term
"Proprietary Information" shall mean all trade secrets or confidential or
proprietary information designated as such in writing by the Disclosing Party,
whether by letter or by the use of an appropriate proprietary stamp or legend,
prior to or at the time any such trade secret or confidential or proprietary
information is disclosed by the Disclosing Party to the Recipient.
Notwithstanding the foregoing, information which is orally or visually disclosed
to the Recipient by the Disclosing Party, or is disclosed in writing without an
appropriate letter, proprietary stamp or legend, shall constitute Proprietary
Information if (i) it would be apparent to a reasonable person, familiar with
the Disclosing Party's business and the industry in which it operates, that such
information is of a confidential or proprietary nature the maintenance of which
is important to the Disclosing Party or if (ii) the Disclosing Party, within
thirty (30) days after such disclosure, delivers to the Recipient a written
document or documents describing such information and referencing the place and
date of such oral, visual or written disclosure and the names of the employees
or officers of the Recipient to whom such disclosure was made. In addition, the
term "Proprietary Information" shall be deemed to include: (a) any notes,
analyses, compilations, studies, interpretations, memoranda or other documents
prepared by the Recipient or its Representatives which contain, reflect or are
based upon, in whole or in part, any Proprietary Information furnished to the
Recipient or its Representatives pursuant hereto; and (b) the existence or
status of, and any information concerning, the discussions between the parties
concerning the possible establishment of a business relationship.

         3.       Use and Disclosure of Proprietary Information. The Recipient
and its Representatives shall use the Proprietary Information of the Disclosing
Party only for the Purposes and such Proprietary Information shall not be used
for any other purpose without the

<PAGE>

prior written consent of the Disclosing Party. The Recipient and its
Representatives shall hold in confidence, and shall not disclose any Proprietary
Information of the Disclosing Party; provided, however, that (i) the Recipient
may make any disclosure of such information to which the Disclosing Party gives
its prior written consent; and (ii) any of the Proprietary Information may be
disclosed by the Recipient to its Representatives who need to know such
information in connection with the Purposes and who are informed of the
confidential nature of such information and of the terms of this Agreement. In
any event, the Recipient shall be responsible for any breach of this Agreement
by any of its Representatives, and agrees, at its sole expense, to take
reasonable measures to restrain its Representatives from prohibited or
unauthorized disclosure or use of the Proprietary Information. Notwithstanding
anything contained in this Agreement to the contrary, this Agreement shall not
prohibit the Recipient from disclosing Proprietary Information of the Disclosing
Party to the extent required in order for the Recipient to comply with
applicable laws and regulations, provided that the Recipient provides prior
written notice of such required disclosure to the Disclosing Party and takes
reasonable and lawful actions to avoid and/or minimize the extent of such
disclosure.

         4.       Limitation on Obligations. The obligations of the Recipient
specified in Section 3 above shall not apply, and the Recipient shall have no
further obligations, with respect to any Proprietary Information to the extent
that such Proprietary Information:

                  (a)      is generally known to the public at the time of
disclosure or becomes generally known without Recipient or its Representatives
violating this Agreement;

                  (b)      is in the Recipient's possession at the time of
disclosure;

                  (c)      becomes known to the Recipient through disclosure by
sources other than the Disclosing Party without such sources violating any
confidentiality obligations to the Disclosing Party; or

                  (d)      is independently developed by the Recipient without
reference to or reliance upon the Disclosing Party's Proprietary Information.

         5.       Ownership of Proprietary Information. The Recipient agrees
that it shall not receive any right, title or interest in, or any license or
right to use, the Disclosing Party's Proprietary Information or any patent,
copyright, trade secret, trademark or other intellectual property rights
therein, by implication or otherwise. Each of the parties hereto represents,
warrants and covenants that the trade secrets which it discloses to the other
party pursuant to this Agreement have not been stolen, appropriated, obtained or
converted without authorization.

         6.       Return of Proprietary Information. The Recipient shall, upon
the written request of the Disclosing Party, return to the Disclosing Party all
Proprietary Information received by the Recipient or its Representatives from
the Disclosing Party (and all copies and reproductions thereof). In addition,
the Recipient shall destroy: (i) any notes, reports or other documents prepared
by the Recipient which contain Proprietary Information of the Disclosing Party;
and (ii) any Proprietary Information of the Disclosing Party (and all copies and
reproductions thereof) which is in electronic form or cannot otherwise be
returned to the Disclosing Party. Alternatively, upon written request of the
Disclosing Party, the Recipient shall destroy all

                                      -2-
<PAGE>

Proprietary Information received by the Recipient or its Representatives from
the Disclosing Party (and all copies and reproduction thereof) and any notes,
reports or other documents prepared by the Recipient which contain Proprietary
Information of the Disclosing Party. Notwithstanding the return or destruction
of the Proprietary Information, the Recipient and its Representatives will
continue to be bound by their obligations of confidentiality and other
obligations hereunder.

         7.       Miscellaneous.

                  (a)      This Agreement supersedes all prior agreements,
written or oral, between the parties relating to the subject matter of this
Agreement. This Agreement may not be modified, changed or discharged, in whole
or in part, except by an agreement in writing signed by the parties.

                  (b)      This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective heirs, successors and
assigns.

                  (c)      This Agreement shall be construed and interpreted in
accordance with the internal laws of the Commonwealth of Massachusetts, without
giving effect to the principles of conflicts of law thereof.

                  (d)      The provisions of this Agreement are necessary for
the protection of the business and goodwill of the parties and are considered by
the parties to be reasonable for such purpose. The Recipient agrees that any
breach of this Agreement may cause the Disclosing Party substantial and
irreparable injury and, therefore, in the event of any such breach, in addition
to other remedies which may be available, the Disclosing Party shall have the
right to seek specific performance and other injunctive and equitable relief.

                  (e)      The confidentiality obligations imposed by this
Agreement shall continue with respect to a particular item of Proprietary
Information until the fifth anniversary of the disclosure of such Proprietary
Information to Recipient pursuant to this Agreement; provided, however, that the
confidentiality obligations imposed by this Agreement with respect to source
code included in the Proprietary Information shall continue in perpetuity.

                  (f)      For the convenience of the parties, this Agreement
may be executed by facsimile and in counterparts, each of which shall be deemed
to be an original, and both of which taken together, shall constitute one
agreement binding on both parties.
