NATURE OF THE PARTNERSHIP
It is with mutual understanding between SLi and DEMARCO to enter into a
strategic partnership agreement, where DEMARCO has relationships and contracts
with various organizations to perform energy efficient lighting retrofits and
energy management services, and SLi is in the energy efficient lighting business
and agrees to become the primary company rendering for DeMarco services such as:
energy audits, energy-related feasibility studies, lighting system
removal/demolition, lighting system installation/retrofit, and energy management
services for commercial, industrial and institutional applications. The
relationship description, contributions, terms, conditions, and other covenants
are set forth herein.
1)       PURPOSE. The purpose of this agreement is to engage SLi to perform as
         Subcontractor for the services described with the attached AIA Document
         A401-1997 for the contracts and/or work orders issued to DEMARCO.
         DEMARCO will perform their duties and responsibilities as described in
         the AIA document, plus any other duties and responsibilities required
         to assist SLi with performing their obligations. Each party will
         perform all individual duties, responsibilities and requirements as set
         forth in this agreement and the AIA agreement.
2)       COMMENCEMENT. Effective immediately, DEMARCO will issue work orders
         relating to lighting systems installation, retrofit and/or demolition
         to SLi, and SLi agrees to perform the services required of each work
         order or contract for and on behalf of DEMARCO.
3)       DURATION. The duration of this agreement is perpetual until such time
         either party wishes to terminate the relationship, and does so by
         furnishing written notice of their intent to terminate at least 60 days
         prior to the effective date. All contracts in-works, services being
         performed at that time and work orders under construction by SLi will
         be performed through completion, regardless of time requirements to
         fulfill the project's work scope. Failure to perform will result in a
         reduction in final payment, based upon percentage of completion, less
         reasonable expenses.
4)       MUTUAL NON-DISCLOSURE. It is understood that DEMARCO and SLi have
         individually entered into Mutual Non-Disclosure Agreements with certain
         companies, and each agrees to honor and carry-out the terms of the
         others agreement(s), unless otherwise agreed to in writing and attached
         hereto. A mutual Non-Disclosure agreement has been executed between
         DEMARCO and SLi and is attached hereto.
5)       NON-COMPETE. DEMARCO and SLi agree to not compete with each other for
         the same contracts or work orders for the duration of this agreement.
         It is understood that each have individually negotiated and/or earned
         contracts prior to this agreement, or have contracts or work orders not
         yet issued, but are considered in process to be issued, and that these
         work orders or agreements are not in direct competition between DEMARCO
         and SLi. It is further agreed each company will establish a system to
         notify the other of contracts under negotiation and subsequent date
         awarded, and that either company will not individually bid for the
         other company's work contracts without receiving prior written
         permission to conduct such activities from that company. If for
         whatever reason a contract (regardless of status `under negotiation' or
         `awarded') is considered to be in competition between either company,
         then the default decision shall go to SLi, unless it is reasonably
         determined otherwise by each party, or that DEMARCO had previously made
         initial contact or introduction first and was capable of performing
         services required to fulfill its obligations under such contract.
6)       COMPENSATION FOR SERVICES. DEMARCO agrees to pay to SLi the entire bid
         amount for each contract awarded to DEMARCO for the services agreed to
         be performed and completed by SLi. It is understood by each party that
         each bid submitted by SLi to DEMARCO shall include and reflect a five
         percent profit for DEMARCO, calculated and added to the sum total of
         SLi's bid. Upon receipt of final payment for each project, DEMARCO will
         retain their five percent profit and distribute the balance to SLi
         within ten days of receipt, unless otherwise agreed to in writing prior
         to each project's bid submission.
