As the plant nears completion, Renegy currently expects that the final cost of the facility will exceed its original budget by approximately $12.5 million. Approximately half of this increase is attributable to cost overruns resulting from rising costs of labor, building materials and other construction challenges, while the remainder is attributable to new investments in the plant including a complete overhaul of the turbine, condenser and other used components, as well as new buildings and equipment added to the scope of the project over the past few months. As previously contemplated by the Contribution and Merger Agreement, Renegy will contribute $2.0 million toward the total amount of cost overruns. In addition, Renegy will pay for $6.0 million of the new capital investments described above that have been, or may be, incurred relating to the acquisition of new assets and other plant enhancements that are expected to further increase the efficiency, reliability and long-term operating performance of the plant. The balance of any costs in excess of the original budget will be paid by Renegy's Chairman and CEO Bob Worsley as outlined in the CMA.

Despite the amount of cost overruns and investment in plant upgrades as outlined above, the capital cost of the 24 megawatt plant, excluding financing and other soft costs, is currently expected to total $58.5 million, which remains below industry estimates of the cost to build a new biomass plant, which range from $2,500 to $3,000 per kilowatt. Furthermore, Renegy's $6.0 million investment in plant enhancements is expected to be substantially offset by a projected reduction in the costs expected to be necessary to refurbish and commission a recently acquired biomass facility in Susanville, California, resulting from its plans to maintain the plant at its current location. More information on the Company's Susanville plant can be found in a separate release issued.

"We are rapidly approaching some key milestones relating to the completion and commissioning of our Snowflake facility that should enable us to begin generating electrical power in the second quarter of this year," stated Bob Worsley. "While disappointed in the cost increases, I am pleased to report that we are on track to fire the boiler later this month and to complete a performance test of the entire plant during April. The additional investment we have elected to make is expected to improve the economics of the plant over the long-term by increasing its potential to achieve higher performance and greater availability, while at the same time reducing operating and maintenance costs. While our original cost projections have been impacted by a variety of internal and external forces, including a significant rise in the cost of building materials being generally experienced in national and global markets, we remain focused on completing the plant in both a timely and quality manner to meet the obligations under our financing, insurance and power purchase agreements."

Worsley continued, "In addition to the impending start-up of our first plant, we continue to be enthusiastic about the growth prospects for biomass energy and the many opportunities we have identified in the marketplace to acquire existing biomass to electricity facilities and related businesses that complement our current business activities."

As a result of the increased capital investment in the plant, combined with its growth objectives, Renegy may seek additional debt or equity financing in 2008 to fund the refurbishment of its Susanville biomass plant and other strategic opportunities, as well as for general corporate purposes. In the interim, to neutralize the impact of the $6.0 million of additional investment in the Snowflake plant, Bob Worsley has agreed to provide the Company with a $6.0 million revolving line of credit from which the Company may draw, if needed, for any near-term cash needs. In parallel, Bob Worsley has agreed to personally guarantee up to $6.0 million should the Company choose to pursue an alternate revolving line of credit with a financial institution. Access to either such credit line will allow Renegy to seek additional financing at a measured pace as growth opportunities arise. The Company is also continuing its search for the addition of a chief operating officer with significant power industry and plant construction experience to add depth to its management team and oversee the development and commissioning of future biomass power generating facilities.

In other news, it was announced Monday that AbitibiBowater ("Abitibi") has agreed to sell its Snowflake, Arizona newsprint mill, the site of Renegy's Snowflake biomass plant, to British Columbia-based Catalyst Paper Corp., a leading North American producer of mechanical printing papers. According to the announcement, Catalyst Paper intends to continue operating the Snowflake paper mill as a means to strengthen its competitive position and market share by having a greater presence on the west coast of North America. Renegy currently has a 25-year lease and operating agreement (including a 25-year option) in place with Abitibi associated with its Snowflake biomass plant. As part of these agreements, Abitibi will supply recycled paper sludge produced by the mill, which is estimated to make up approximately 50% by weight (25% by energy content) of the biomass fuel to be used by Renegy's Snowflake plant. All such agreements currently in place with Abitibi remain intact and are enforceable under the new ownership scenario.

Renegy is also announcing today that it has completed its determination of final transaction costs and working capital adjustments associated with the $9.6 million sale of its SCR-Tech subsidiary last November. As previously noted, current stockholders of Renegy will receive additional value through an increased percentage of ownership in Renegy common stock based on the net cash proceeds of the SCR-Tech sale, which have been calculated at $9.3 million. After expenses and working capital adjustments required under the CMA relating to the combination of the businesses of Catalytica Energy Systems and the renewable energy divisions of NZ Legacy, LLC last October, the final net effect is an approximate 1.5% reduction in Renegy common stock currently owned by the Worsley Trust. Accordingly, current stockholders of Renegy now own approximately 42.8% of the outstanding common stock of Renegy and the Worsley Trust approximately 57.2%.
