SIONIX Announces Sale of Two Elixir 225/RO

Water Treatment Systems

Systems to be used to treat brine water discharge

from Arkansas oil wells

IRVINE, Calif. - June 12, 2008 - SIONIX Corporation (OTCBB: SINX) (“SIONIX”) today announced it has received a Purchase Order for two Elixir 225/RO Water Treatment Systems at a price of $1.8 million per unit. On June 6, 2008, a cash deposit of $900,000 for the first unit accompanied the purchase order and the deposit for the second unit is to follow within 45 days.

The Systems are being purchased by Innovated Water Equipment, Inc. (IWE), a Little Rock, Arkansas-based master distributor of SIONIX and servicer of oil drilling companies. IWE plans to use the desalination systems to separate petroleum and reduce the salt content, among other things, from the brine water discharge from its clients’ oil wells for reuse by the client or to be safely returned to the environment.

James Houtz, President and COO of SIONIX, stated “This is one example of the myriad of applications for which the Elixir 225/RO System provides a compelling water treatment solution. Because the Elixir 225/RO System is pre-packaged, SIONIX offers faster delivery, easy installation and portability, all at low capital and operating costs compared to the alternatives. This is an ideal solution for the oil drilling industry and an environmentally sound manner for reusing or returning water to the environment.”

Jeffrey Mann, President of Innovated Water Equipment, Inc., stated “We chose this system after deliberating how to effectively and efficiently return the water generated from drilling into the environment in the preferable manner for water reclamation. While other systems required longer-lead times and costly installation, they were unable to meet the required specifications. The Elixir 225/RO’s portability and self-contained design fit our application better than any of the alternatives.”

Richard Papalian, CEO of SIONIX, stated “As regulations have become stricter and the cost of trucking and processing brine water increases, the cost advantage and packaged nature of our system allows operators to affordably decentralize processing.”

The Elixir 225/GS water treatment system, which is another model of SIONIX’ water treatment product, has been implemented and is being tested at the Villa Park Dam in Orange, California. The Serrano Water District agreed to the implementation and testing of the Elixir 225/GS water treatment system in an effort to support the exploration of an affordable solution for reducing the high levels of iron and manganese in its water stream. The Villa Park Dam is a flood retention dam on Santiago Creek upstream from the Serrano Water District Treatment Plant. The dam retains water from runoff and spring flow but in general, large flood flows are not allowed to accumulate behind the dam. The reservoir capacity is 16,000 acrefeet and the average impoundment varies between 150 and 750 acrefeet during the year. The Serrano Water District has been unwilling to utilize this water because of the historically high costs associated with removing the very high quantities of iron and manganese in the reservoir water. The chemical cost to reach the below MCL target using the Elixir 225/GS System is approximately $0.18 per 1,000 gallons. With the treatment of iron and manganese, the test results would indicate that the water behind the Villa Park Dam could become suitable for the Serrano Water Treatment Plant to process and distribute to its customers.

In addition to the $900,000 up front deposit on June 6, 2008, a second payment of $360,000 for the first unit is due within 90 days. A third payment of $360,000 is due prior to shipment of the first unit, and the balance payment of $180,000 for the first unit is due upon the delivery, installation and satisfactory operation of the first unit. Within 10 days of the date of the purchase order, the purchaser will apply for financing to purchase the second unit, and a deposit of $900,000 for the second is due upon the purchaser’s receipt of such financing. SIONIX reserves the right to rescind the multiple unit discount if the purchaser does not pay the full deposit for the second unit within 45 days of June 6, 2008, the date of the purchase order.
