M-Wave to Merge with SunFuels and Blue Sun a leading biodiesel company

SunFuels completes $10.125 million equity investment in connection with merger

Denver, CO and Franklin Park, IL (January 29, 2007) - SunFuels, Inc. (“SunFuels”) a leading biodiesel fuel company, Blue Sun Biodiesel LLC (“Blue Sun”), the operating subsidiary of SunFuels, and M-Wave, Inc. (NasdaqCM: MWAV) (“M-Wave”) jointly announced today that they entered into a definitive merger agreement whereby SunFuels and Blue Sun would merge into a wholly-owned subsidiary of M-Wave. The transaction is expected to close in the second quarter of 2007, pending satisfaction of conditions to closing. When the transaction closes, certain directors and the officers of SunFuels will assume control of M-Wave, which will change its name to Blue Sun Holdings, Inc. (the “Company”). The Company’s operating subsidiary will be renamed Blue Sun Biodiesel, Inc. The Company will continue to be a publicly traded and reporting company following the closing of the transaction.

Jeff Probst, President and CEO of SunFuels and Blue Sun, said, “SunFuels is merging with M-Wave as part of Blue Sun’s strategy to meet expanding consumer demand for high-quality, premium-performance biodiesel fuel. We believe that now is an ideal time to be positioned as a public company in the biodiesel fuel business. With this transaction and our investors, Blue Sun is fully prepared to expand its business strategy and to meet the growing demand for high-quality biodiesel fuels.”

Joe Turek, Chairman and President of M-Wave, commented: "This transaction represents a milestone in our efforts to provide value to our stockholders. We are excited to have M-Wave play a role in the growing biodiesel market in the United States. We look at this transaction as a significant positive event for the company."

In addition to the merger transaction, SunFuels completed a $10.125 million private placement of its Series A Convertible Preferred Stock. The Series A Convertible Preferred Stock is convertible into SunFuels Common Stock. In connection with the issuance of the Series A Convertible Preferred Stock, SunFuels also issued warrants to purchase additional shares of SunFuels Common Stock to the investors in this round of financing. M.A.G. Capital, LLC, a Los Angeles-based private investment firm, was the lead investor in the Series A financing, which included one other institutional investor. In addition, M.A.G. Capital committed to purchase $10.125 million in additional Series A Convertible Preferred Stock upon the closing of the merger transaction.

Jeff Probst of SunFuels and Blue Sun commented, “As a leading vertically integrated biodiesel company, the $20.25 million equity investment provides the company with the capital necessary to complete construction of biodiesel refinery assets aggregating 45 million gallons of biodiesel per year. We intend to begin construction of our first biodiesel refinery site at Clovis, New Mexico immediately and to continue to build out our vertically integrated business model, including the construction of oilseed crushing facilities and advanced biodiesel blending terminals. With the combination of this merger transaction and the infusion of equity capital, we believe we will be well positioned to compete in the burgeoning biodiesel market in the United States.”

As consideration for the merger transaction, the outstanding equity securities of SunFuels will be exchanged for equity securities of M-Wave. Specifically, outstanding SunFuels Common Stock, Series A Convertible Preferred Stock, options and warrants will be exchanged for Company Common Stock, Series C Convertible Preferred Stock, options and warrants, respectively. As a result, the holders of such SunFuels equity securities will own 87.2% of the Common Stock of the Company, on a fully-diluted basis, assuming (i) the completion of the SunFuels Series A Convertible Preferred Stock financing described below and (ii) conversion or exercise of all convertible or exercisable securities of the Company that will be outstanding after the completion of the merger. Similarly, all of the outstanding Blue Sun membership interests not already owned by SunFuels will be exchanged for shares of Company Common Stock. As a result, the holders of such Blue Sun membership interests will own 3.8% of the Common Stock of the Company, as so calculated on a fully-diluted basis. The currently outstanding shares of M-Wave Common Stock will remain outstanding and, following the exchange of SunFuels and Blue Sun equity securities for M-Wave equity securities, the currently outstanding shares, warrants and options of M-Wave will represent 9.0% of the outstanding shares, warrants, and options of the Company, as so calculated on a fully-diluted basis.

The merger transaction is subject to the approval by the stockholders of M-Wave and SunFuels and the members of Blue Sun, receipt of all required consents, receipt of all regulatory approvals, and other customary closing conditions. Holders of a majority of the outstanding shares of each class of stock of SunFuels and holders of approximately 48% of the outstanding shares of Common Stock of M-Wave and 100% of the outstanding shares of each class of preferred stock of M-Wave have agreed to vote in favor of the mergers. SunFuels, which holds 94.4% of the oustanding Blue Sun membership interests, has agreed to the Blue Sun merger. In addition, the merger transaction is subject to the receipt of the remaining $10.125 million in SunFuels Series A Convertible Preferred Stock. There can be no assurances that SunFuels will receive the remaining $10.125 million or that the merger transaction will be completed as contemplated.

Because the holders of the equity securities of SunFuels will acquire a majority of M-Wave’s shares of capital stock as a result of the merger transaction, the merger transaction will be treated as a reverse merger for accounting purposes, and SunFuels will be deemed to be the acquiror in the reverse merger. Consequently, the historical financial statements of the Company will be the historical financial statements of SunFuels rather than the historical financial statements of M-Wave, and the assets and liabilities of SunFuels will be recorded at their historical cost basis to SunFuels, and the assets and liabilities of M-Wave will be recorded as if they were purchased on the closing date at their fair market value on that date.
