WorldWater & Solar Technologies Announces Completion of ENTECH Merger

WorldWater & Solar Technologies Corp. (OTC BB: WWAT.OB), developer
and marketer of proprietary high-power solar systems, today announced
that it has closed the merger with ENTECH, Inc. of Keller, Texas. This
transaction was made possible through agreement with one of
WorldWater´s largest investors, the Quercus Trust (Quercus). Quercus
exchanged 19.7 million of its common shares of WorldWater for 19,700
shares of convertible preferred stock and supplied WWAT with a $6
million bridge loan. The 19.7 million common shares and the bridge
loan were subsequently utilized to complete the ENTECH merger.

Pursuant to the exchange agreement, once a shareholders meeting is
held and additional common shares are authorized, a subsequent
exchange with Quercus will be implemented. As a result, Quercus will
receive 19.7 million common shares in exchange for the 19,700 shares
of convertible preferred stock previously issued.

"The Quercus Trust, which has been an investor in our company
since last spring, has demonstrated its strong commitment to both
WorldWater and ENTECH by making this transaction possible on an
expedited basis," said Quentin T. Kelly, Chairman and CEO. "As our
investors know, the merger with ENTECH, 19 months in the making, paves
the way for our company to provide 20x concentrator PV systems to the
U.S. and international markets at costs among the lowest of all solar
suppliers, including thin film manufacturers. Quercus made it possible
to move forward without further delays, allowing us to take advantage
of the many opportunities now on the table across the globe. With
solar energy taking on greater significance both in the U.S. and
overseas -- and oil prices at near all-time highs -- we simply could
not wait any longer to merge our two companies and leverage the
resulting synergies. Quercus enabled this to happen."

Dr. Walter Hesse, CEO of ENTECH, commented, "This is terrific. Now
ENTECH and WorldWater & Solar Technologies can proceed with the
production of our 20x concentrator lines. Together with WorldWater, we
will be able to supply ´solar farms´ throughout the world with
electricity production at costs and efficiencies that we believe
change the current economics of solar power - making it affordable to
millions."
