final construction designs for each of the residences on the property that may
or may not then fall within the cost estimates derived from certain assumptions
expected for homes of a particular square footage using certain construction

with geothermal heat pumps manufactured by EIC. The mechanical design and
installation within each home is also critical to assure the best system
operating conditions possible, and EIC brings with it expertise like none other
in the local marketplace, in terms of mechanical system design and ducting
installation systems for geothermal heat pumps.

20.0     Emission Credits

Gas, Carbon Dioxide or other pollution related Credits which may or may not be
applicable at any time on the site due to the energy efficiency or energy
reduction capacity of the geothermal heat pumps exclusively

sold and provided to the homeowner by EIC. Any updating or improvement to the
technology by EIC of the system owned by EIC which results in further
conventional energy usage reduction resulting in any further Credits, will be to
the sole account of EIC and EIC shall have the unrestricted right of ownership
or trade of such Credits resulting form the efficiency of its equipment, system,
design and continuing usage at and on the Owner's premises.

3.1.3    An IGSHPA Accredited Installer or a certified Geothermal Service
         Contractor will and must install HDPE pipe through Essential
         Innovations.

3.1.4    Socket- and butt-fusion are the only acceptable processes for fusing
         HDPE pipe and its fittings, and the fusion process must follow
         manufacturer's written instructions.

3.1.5    Elbow fittings are to be installed where a sharp bend would occur
         otherwise.


4.       Ground Heat Exchanger Piping

4.1.1    While on-site, HDPE piping shall be capped or have temporary plugs
         installed to ensure that no debris, soil, and small animals have
         entered the pipe prior to any fusion or installation into the ground or

5.       Vertical Ground Heat Exchanger Systems

5.1.1    Manufactured U-bends will be used to construct the U-tubes.

5.1.2    U-tubes will be piped together in parallel circuit configurations.
         Parallel systems will be used in all vertical ground heat exchangers.

5.1.3    Ground loops shall be pressurized with water during grouting and
         backfilling to avoid pipe collapse.

5.1.4    Grouting of the entire vertical borehole shall be done by pressure
         pumping through a tremie pipe in accordance with IGSHPA guidelines and
         with all provincial and local requirements. Grout material may contain
         smooth, small rocks, but not sharp, jagged rocks or large rocks that
         may puncture the HDPE pipe.

Additional grout may be required due to settling of the initial grout. The
contractor shall monitor each borehole and provide additional grout where
necessary.

EI Minimum Maintenance Specifications for "Strata":

"Strata" is responsible for purchasing the following maintenance terms from
Essential Innovations in regards to the actual Heat Pump installations in each
of the homes:

         1.       A maintenance check-up, by a licensed refrigeration mechanic
                  or EI approved equivalent, shall be conducted. The interval
                  between check-ups shall be no longer than six (6) months. A
                  three (3) month interval between maintenance check-ups is
                  recommended.

         2.       During each maintenance check-up, the following items are to
                  be completed for the water-to-air heat pumps:

                  o        Air filter changes
                  o        Clean condensate drip pan and clean/flush its
                           condensate pipe (algaecide may be required)
                  o        Vacuum air-side of coil and internal areas where dirt
                           may accumulate (care must be taken not to damage the
                           aluminum fins)
                  o        Clean fan, plenum above fan coil, and wall panels of
                           any dirt/mold accumulation
                  o        Check hose connections and associated pipes for leaks
                  o        Check fan coil for excessive noise and vibration

         3.       During each annual maintenance check-up, recording of
                  performance measurement data is required. This data shall
                  include volts, amps and water temperature difference. This
                  data shall be compared to the information on each heat pump
                  unit's data plate and the data taken at the original equipment
                  start-up. The measurement data shall be reported to EI.

         4.       During each annual maintenance check-up, the electrical
                  operation of contactors, relays and reset switches will be
                  checked, while ensuring all wires are connected tight. As
                  well, the fan will be checked for imbalance and bent blades.
                  The verification of these components shall be provided to EI.
                  A maintenance check sheet will be provided at the completion
                  of the project, which will include the above items, as well as
                  additional maintenance items for up keeping the system to its
                  utmost potential.

EI Maintenance Responsibilities:

EI will repair, replace and maintain all buried pipes, headers and distribution
feeds, all in ground valves, monitor switches, flow control regulators and check
valves at its sole and exclusive cost, as required. All fluid within the pipes
will be maintained by EI exclusively.

         spacing. The HDPE pipe shall be supplied by Essential Innovations and
         is SDR 11, 448 Standard, 1 inch with a 50+ year Warranty.

3.       All trenching and dewatering costs for Horizontal ground works. This
         involves using a small backhoe for a few days and is normally
         coordinated among other on site activities. Dewatering is not likely
         required but no costs were involved in this proposal for this event.

4.       Labour to commission the drilling, oversee the drilling, install the
         loop pipe, manage the mixing and feeding the grout into the boreholes,
         fusing the headers, purging the loop field and running the series of
         horizontal headers to the expected location of the building foundation

To EIC from DDL:

DDL agrees to put into their lot disclosure statement, language to the effect
that "EIC is the sole and exclusive provider of Geothermal Systems and Services
to the Diamondview project. When you (the buyer) purchase a lot in the
Diamondview project you (the buyer), hereby commit to an on-going monthly fee
payment to EIC for a term of 25 years, for the use of the geothermal loop field
EI installs on each of the homesites, and you (the buyer) additionally commit
exclusively to the utilization of a geothermal heat pump in your residence for
heating and cooling purposes, such geothermal heat pump to be both manufactured
by EIC and installed by EIC and only EIC, unless specifically and otherwise
determined by EIC.

Diamondview residents will purchase geothermal heat pumps and associated
equipment from EIC based on a .55 multiplier from the EIC price list. In home
equipment installation services will be quoted and determined on a job-by-job
basis, and will be charged to the homeowner at better than fair market value.

First Right of Refusal on Future Available Lots for Development

Based on current discussions between the DDL and EIC, it is expected that in all
likelihood there may be additional single-family lots available in the next
phase of the Diamondview project on a lower parcel of land under their control.
In this case, assuming that there are further lots for development, then DDL
agrees that EIC is also hereby given the first right of refusal for the heating
and cooling component of that phase of the project to act in the role of
Geothermal provider for these future lots should they wish to do so.
