Primex Plastics installed dynamic VAR compensation systems from Quality Energy at its Corsicana, TX plant to reduce energy costs and carbon footprint. Quality Energy monitored the plant's energy usage and power quality before and after installing the systems. The data showed significant decreases in current, reactive power, and energy usage, along with increases in voltage and power factor. This resulted in estimated annual savings of $73,044 from reduced electricity costs and equipment repairs along with less downtime. The systems also improved power quality issues that were causing electrical problems. Quality Energy delivered 171% of the projected annual savings and recommends adjusting the main transformer voltage slightly lower based on the increased voltage from the systems.

Measurement and Verification
Primex Plastics is making a concentrated effort toward sustainability and profitability by reducing their carbon footprint
and ongoing energy costs in all US plants. The Corsicana, TX plant was chosen as a pilot plant to test the claims made by
Quality Energy that, the utilization of Elspec dynamic VAR compensation systems would reduce the power consumed,
improve power factor, increase the total capacity of the existing electrical infrastructure and improve plant power
quality. To verify these claims, prior to the installation of the Elspec systems, Quality Energy installed our Elspec G4k
Class A electrical meter at the main switch gear of the Corsicana, TX facility. The G4k recorded energy usage and power
quality data before and after the installation of the three Elspec systems located at the main switchgear and at extrusion
lines 4 & 6. The following graph details the data recorded by the G4k meter and illustrates energy parameters before
and after commissioning the 3 Elspec systems November 7, 2008 as represented below:
The data illustrates several positive results which verify the forecasted savings in our proposal. Data from the above
illustrates a significant increase in voltage and power factor coupled with an equally significant decrease in current, KVar
and watts consumed. This data and the financial impact are illustrated in the table on the following page.

DOWN TIME** $9,000.00
EQUIPMENT REPAIR** $7,000.00
**FROM CUSTOMER SUPPLIED DATA TOTAL ANNUAL SAVINGS $73,044.43
Conclusions:
Total amp load & wattage for the entire plant was reduced by 26.5% and 10.3% respectively. Also, it is important to note
the KW demand is reduced by 3.3%. In many of your plant locations, this could be a larger portion of total savings based
on local utility tariffs.
The results in a KVAR reduction of over 60.62% will enable expansion of an additional line in the Corsican, TX operation
without the need for expensive expansion in electrical infrastructure.
The results in a KWH reduction of almost 10.3% will be directly reflected in the Constellation New Energy bill. Based on
the past 12 months bills (EXHIBIT 1 attached) show the electrical usage totaled 4,440,441 KWH annualized to 4,591,894.

In our proposal to management for this pilot plant Figure 3
dated August 8, 2008, we projected ongoing annual costs reductions of $61,810 and have delivered $73,043 or 171% of
projected savings. Additionally, the electrical network in the plant will realize a substantially improved power quality
environment and the subsequent negative impacts on equipment repair and down time will be reduced.

4. The Elspec systems also increased
the voltage in the facility by 9.2
volts over the existing level of
489.2 volts to 498.4 volts. After a
few months of operation with all
Elspecs operating we would like
your permission to approach the
utility provider with the
recommendation of a “tap down”
of 2.5% on the main transformer
providing power to the plant. If
this is possible, additional savings
of 4% or more in KWH
consumption may be achievable.
The graph of “Comparison of
Investments” illustrates the long
range financial benefit of this
project compared to a 9%
certificate of deposit, based on the results of the pilot plant in TX. We look forward to evaluating the savings potential
at other Primex Plastics locations. It is our sincere belief that similar energy savings opportunities exist throughout your
company.
Sincerely,
Phil Mullins
