Commitment
       The following are the terms of the ENERGY STAR Partnership Agreement as it pertains to the
manufacturing of ENERGY STAR qualified boilers. The ENERGY STAR Partner must adhere to the following
program requirements:

•       comply with current ENERGY STAR Eligibility Criteria, defining the performance criteria that must be
       met for use of the ENERGY STAR certification mark on boilers and specifying the testing criteria for
       boilers.  EPA may, at its discretion, conduct tests on products that are referred to as ENERGY STAR
       qualified. These products may be obtained on the open market, or voluntarily supplied by Partner
       at EPA's request;

       comply with current ENERGY STAR Logo Use Guidelines, describing how the ENERGY STAR labels
       and name may be used.  Partner is responsible for adhering to these guidelines and for ensuring
       that its authorized representatives, such as advertising  agencies, dealers, and distributors, are
       also in compliance;

       qualify at least one ENERGY STAR labeled boiler or model within one year of activating the boilers
       and combination space-heating and water heating portion of the agreement.  When Partner
       qualifies the  product, it must meet the specification (e.g., Tier 1 or 2) in effect at that time;

•       provide clear and consistent labeling of ENERGY STAR qualified boilers. The ENERGY STAR label
       must be clearly displayed in product literature (i.e., user manuals, spec sheets, etc.) and on the
       manufacturer's Internet site where information about ENERGY STAR qualified models is displayed.
       It is also recommended that the label appear on the top/front of the product and on the product
       packaging;

       offer and encourage training to distributors and/or contractors on the following issues:  system
       venting, condensate removal, code compliance, and proper use of the Manual J calculation, or
       other equivalent calculation, in order to encourage proper sizing of equipment;

•       provide to EPA, on an annual basis, an updated list of ENERGY STAR qualifying boiler models.
       Once the Partner submits its first list of ENERGY STAR labeled boiler models, the Partner will be
       listed as an ENERGY STAR Partner.  Partner must provide annual updates in order to remain on the
       list of participating product manufacturers;

•       provide to EPA, on an annual basis, unit shipment data or other market indicators to assist in
       determining the market penetration of ENERGY STAR. Specifically, Partner must submit the total
       number of ENERGY STAR qualified boilers shipped (in units by model) or an equivalent
       measurement as agreed to in advance  by EPA and  Partner. Partner is also encouraged to
       provide ENERGY STAR qualified unit shipment data segmented  by meaningful product
       characteristics (e.g., capacity, size, speed, or other as relevant), total unit shipments for each
       model in its product line, and percent of total unit shipments that qualify as ENERGY STAR. The
       data for each calendar year should be submitted to EPA, preferably in electronic format, no later
       than the following March and may be provided directly from the Partner or through a third party.
       The data will be used  by EPA only for program evaluation purposes and will be closely controlled.
        If requested under the Freedom of Information Act (FOIA), EPA will argue that the data is exempt.

        Any information used will be masked by EPA so as to protect the confidentiality of the Partner;

•      notify EPA of a change in the designated responsible party or contacts for boilers within 30 days.

Performance for Special Distinction
       In order to receive additional recognition and/or support from EPA for its efforts within the
Partnership, the ENERGY STAR Partner may consider the following voluntary measures and should  keep
EPA informed on the progress of these efforts:

       consider energy efficiency improvements in company facilities and pursue the ENERGY STAR label
       for buildings;

•      purchase ENERGY STAR labeled products.  Revise the company purchasing or procurement
       specifications to include ENERGY STAR.  Provide procurement officials' contact information  to EPA
       for periodic updates and coordination. Circulate general ENERGY STAR labeled product information
       to employees for use when purchasing products for their homes;

       ensure the power management feature is enabled on all ENERGY STAR qualified monitors in use in
       company facilities, particularly upon installation and after service  is performed;

•      provide general information about the ENERGY STAR program to employees whose jobs are
       relevant to the development, marketing, sales, and service of current ENERGY STAR labeled
       product models;

       feature the ENERGY STAR label(s) on Partner Web site and in other promotional materials.  If
       information concerning ENERGY STAR is provided on the Partner Web site as specified  by the
       ENERGY STAR Web Linking Policy (this document can be found in the Partner Resources section
       on the ENERGY STAR Web site at www.energystar.gov).  EPA may provide links where appropriate
       to the Partner Web site;

•      provide a simple plan to EPA outlining specific measures Partner plans to  undertake beyond the
       program requirements listed above. By doing so, EPA may be able to coordinate, communicate,
       and/or promote Partner's activities, provide an EPA representative, or include news about the
       event in the ENERGY STAR newsletter, on the ENERGY STAR Web pages, etc. The plan  may be as
       simple as providing a list of planned activities or planned milestones that Partner would like EPA
       to be aware of. For example, activities may include:  (1) increase the availability of ENERGY STAR
       labeled products by converting the entire product line within two years to meet ENERGY STAR
       guidelines; (2) demonstrate the  economic and environmental benefits of energy efficiency  through
       special in-store displays twice a year; (3) provide information to users (via  the Web site and user's
       manual) about energy-saving features and operating characteristics  of ENERGY STAR qualified
       products, and (4) build awareness of the ENERGY STAR Partnership and brand identity by
       collaborating with EPA on one print advertorial and one live press event;

•      provide quarterly, written updates to EPA as to the efforts undertaken by Partner to increase
       availability of ENERGY STAR qualified products, and to promote awareness  of ENERGY STAR and its
       message.

                                                   for Boilers

                                              Eligibility Criteria
Below is the product specification (Version 2.0) for ENERGY STAR qualified boilers.  A product must meet all
of the identified criteria if it is to be labeled as ENERGY STAR by its manufacturer.

1)  Definitions: Below is a brief description of a boiler and other terms as relevant to ENERGY STAR.

    A.  Residential Boiler: A self contained fuel burning appliance of less than 300,000 Btu per hour
       energy input, for supplying low pressure steam or hot water for space heating applications. A
       heating unit that meets this definition and also provides hot water for domestic or other use is
       considered a boiler for purposes of this agreement (see Combination Space-Heating and Water
       Heating Appliance below).

    B.  Combination Space-Heating and Water Heating Appliance: Appliance that provides both space
       conditioning (boiler) and hot water heating with one appliance or energy source. The combination
       appliance circulates hot water from the water heater through a heat exchanger in the air handler.
       A blower will move the heated air through a standard duct system. In the summer,  an air
       conditioner is connected to the exchanger and the system functions similarly, with  cool air being
       pushed through the ductwork.

    C.  AFUE: The Annual Fuel Utilization Efficiency ("AFUE") measures the amount of fuel converted to
       space heat in proportion to the amount of fuel entering the boiler. This  is commonly expressed as
       a percentage.  For purposes of this agreement, the efficiency of a boiler shall be measured using
       AFUE. Test procedures have been developed to test AFUE by the Department  of Energy (DOE).
       These procedures are specified in 10 CFR part 430.

    D.  CAafue: The Combined Appliance Annual Fuel Utilization Efficiency ("CAafue") is the effective
       efficiency of the combined appliance in performing the function of space heating. When the
       primary heating source of the combined appliance is a residential boiler, the CAafue is the same
       as the AFUE of the boiler as determined by DOE test procedures specified in 10 CFR 430.

    E.  Manual J Calculation: A calculation performed to determine the heating load for  a residence or
       small commercial building. The calculation includes site-specific characteristics such as regional
       weather data, building framing  materials, building insulation levels, building air infiltration levels
       and window area.  The calculation follows  procedures and protocols developed by the Air
       Conditioning Contractors of America.

2)  Qualifying Products: Any boiler that meets the  definition in Section 1A is eligible for the ENERGY STAR
    label.

3)  Energy-Efficiency Specifications for Qualifying Products: Only those products listed in Section 2 that
    meet or exceed 85% AFUE (CAafue) energy-efficiency ratings may qualify as ENERGY STAR.

4)  Test Criteria: Manufacturers are required to perform tests and self-certify those product models that
    meet the ENERGY STAR guidelines.  Partner agrees to measure a boiler model's energy efficiency using
    the AFUE for space heating as determined by  DOE using test procedures specified in  10 CFR part
    430. Partner agrees to measure combination space-heater and water  heater appliances based on
    ASHRAE Standard ANSI/ASHRAE 124-1991 "Methods of Testing for Rating Combination Space-
ENERGY STAR Program Requirements for Boilers

-------
    Heating and Water-Heating Appliances."

5)  Effective Date: The date that manufacturers may begin to qualify products as ENERGY STAR will be
    defined as the effective date of the agreement. The ENERGY STAR Boiler specification is effective
    immediately.

6)  Future Specification Revisions: ENERGY STAR reserves the right to change the specification should
    technological  and/or market changes affect its usefulness to consumers, industry, or the environment.
    In keeping with current policy, revisions to the specification are arrived at through industry
    discussions.
