("Acasti") (TSX-V:APO) announces that further to its news release dated February 7, 2012, it has closed a private placement pursuant to which Dr. Harlan Waksal, Acasti's Executive Vice-President, Business & Scientific Affairs, and Neptune Technologies & Bioressources Inc. ("Neptune"), Acasti's parent company, have subscribed to Acasti's capital stocks for total net proceeds of approximately $2,000,000 CDN (the "Offering").

"My involvement in Acasti has progressively evolved since joining the management team in July 2011. Importantly, my current investment is due to my belief that Acasti will grow in value because of the potential of its drug candidate, CaPreTM, which is currently in phase II clinical studies in patients with hypertriglyceridemia." stated Dr. Harlan Waksal.

"It has been very stimulating to work with Dr. Harlan Waksal and we have greatly benefitted from his expertise since he joined Acasti's management team. Having him financially involved is also a testimony of his belief in Acasti's value and a commitment to the company." said Henri Harland, CEO of Acasti. "It's all good news for our shareholders." he added.

Dr. Harlan Waksal has subscribed, for an aggregate consideration of $1,000,000 USD, to 750,000 units of Acasti composed of (i) 750,000 Class "A" common shares in the capital of Acasti at $1.33 USD per share, and (ii) warrants to purchase 750,000 additional shares. The warrants to purchase additional shares will be exercisable at a price of $1.50 CDN and will expire 36 months following their issue date. The warrants will be vesting over a period of two years and a portion of such warrants will be subject to the achievement of certain agreed upon and predefined milestones.

Neptune has subscribed to 750,000 Class "A" common shares in the capital of Acasti at $1.33 CDN per share, for an aggregate consideration of approximately $1,000,000 CDN.

"Contrary to Neptune, Dr. Harlan Waksal has also received warrants in consideration of his investment because of his personal contribution to Acasti's performance." stated Xavier Harland, CFO of Acasti.

The net proceeds of the Offering will be used for general corporate purposes (working capital). All securities issued in connection with the Offering were purchased by persons or entities related to Acasti.
