HOUSTON, TX--(Marketwired - Apr 9, 2013) - Sionix Corporation (OTCQB: SINX) announced today the appointment of Dr. Henry W. Sullivan as its Chief Executive Officer and Chairman of the Sionix Board of Directors.

Dr. Sullivan has been a Director of Sionix since October 2012 and he has been active in the technical and operating management of the company since that time.

Dr. Sullivan holds both a Master's degree and Ph.D. in chemical engineering from New York University, and has held senior positions with Huntsman Petrochemical Corporation and Shell Oil Company for a combined 26 years, where his experience included the optimization of refineries and the allocation of hydrocarbons and their processing and movement. He founded and was CEO of several companies and has served on the Board of several public companies as well as the Sarkeys Energy Center at the University of Oklahoma.

Coincident with the appointment of Henry Sullivan, Ken Calligar has resigned as interim CEO of Sionix and James W. Alexander has resigned as interim Chairman of the Board of Directors of the Company. Both Mr. Alexander and Mr. Calligar will continue to serve on the Sionix Board of Directors.

Mr. Calligar stated, "We are very pleased to have Dr. Henry Sullivan leading Sionix. It is fortunate that someone of Henry's experience and capabilities is available to Sionix. In the past months we have collectively stabilized the company, revised its mission, strategies, and sales and services offerings. We have relocated the company to Houston to facilitate its focus on the oil and gas sector and we have eliminated wasteful policies and practices. This was a team effort. The next steps for Sionix are to establish a track record of its technologies and services. In order to do this, we have assembled an experienced and dedicated team, the appointments of whom we have previously announced. This leadership team, working with our technical staff, will pursue commercial opportunities in treating water produced in oil and gas fracking as well as agricultural, municipal and other water treating applications."

Dr. Sullivan commented, "Our team is looking forward to extending the proprietary Sionix technology and to completing the final phase of pre-commercial testing in the Bakken shale in North Dakota. I have worked closely with Jim Alexander and Ken Calligar since I joined the Board and I am pleased that they will continue to help lead the Company as directors."
