LAVAL, QUÉBEC -- (Marketwired) -- 02/02/17 --

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Acasti Pharma Inc. ("Acasti", "Acasti Pharma" or the "Corporation") (NASDAQ:ACST)(TSX VENTURE:ACST) today announced that it entered into a finder's agreement with Leede Jones Gable Inc. in connection with a proposed private placement of $2 million aggregate principal amount of unsecured convertible debentures and warrants (the "Debenture Warrants") to acquire Class A shares of the Corporation ("Common Shares") with arm's length investors (collectively, the "Private Placement"). It is anticipated that the convertible debentures will be issued at a discount of 3.5% to the principal amount thereof, for aggregate gross proceeds of up to $1.930 million.

The convertible debentures will mature on the date falling on the third anniversary of their date of issuance, subject to the exercise by the Corporation of its prepayment option, and will bear interest at a rate of 8% annually, payable quarterly on the last day of March, June, September and December of each year commencing on March 31, 2017, at the option of the Corporation, (i) in cash, (ii) subject to all necessary regulatory approvals having been obtained, in newly-issued Common Shares, or (iii) any combination of (i) and (ii) above.

The principal amount of the convertible debentures may be converted at the holders' option into Common Shares at a conversion rate of $1.90 per share, subject to customary adjustment provisions.

The maximum number of Common Shares which will be issuable to all holders of convertible debentures pursuant to the terms of the convertible debentures is 5,852,631, namely: 1,052,631 Common Shares issuable upon conversion of the aggregate principal amount and up to an additional 4,800,000 Common Shares issuable in payment of interest owing thereon, subject to customary adjustment provisions.

The convertible debentures will provide the Corporation with an acceleration right whereby the Corporation may, at any time at least four months after the date of issuance of the convertible debentures, accelerate the conversion rights of the holders in the event that the volume weighted average price of the Corporation's Common Shares on the TSX Venture Exchange is equal to or exceeds $2.65, subject to customary adjustment provisions, during 20 consecutive trading days (the "Acceleration Right").

As consideration for the Corporation's right to prepay the convertible debentures, it is anticipated that the Corporation will issue Debenture Warrants to the holders of the convertible debentures to acquire, in the aggregate, up to that number of Common Shares, for the same price, as they would have been entitled to acquire upon the conversion of the outstanding aggregate principal amount of the convertible debentures, namely up to 1,052,631 Common Shares. The Debenture Warrants will have an exercise price equal to $1.90 per Common Share, subject to adjustment in certain circumstances, and a term expiring on the maturity date of the convertible debentures. The expiry of the Debenture Warrants will be subject to acceleration in substantially the same manner as pursuant to the Acceleration Right under the convertible debentures and will be subject to the same adjustment provisions as the convertible debentures, subject to necessary adjustments to reflect the terms of the Debenture Warrants. The Debenture Warrants will not be exercisable prior to the first date on which the Corporation exercises its right to prepay the convertible debentures and, from and after each prepayment date, the Debenture Warrants will only be exercisable on a pro rata basis, in proportion to the aggregate principal amount of convertible debentures which is prepaid up to the relevant prepayment date.

Leede Jones Gable Inc. will be receiving a finder's fee of 1.0% of the aggregate gross proceeds received by the Corporation from the Private Placement, for a total of up to $19,300, which will be payable by the Corporation.

The Private Placement is expected to close concurrently with the Corporation's proposed public offering of units (the "Units") by way of short form prospectus as previously announced on December 5, 2016 (the "Proposed Offering").

Acasti also announced today that it has received a receipt for an amended and restated preliminary short form prospectus (the "Amended and RestatedPreliminary Prospectus") in connection with the previously announced Proposed Offering, revising the minimum and maximum gross proceeds of the Proposed Offering to CAD$4,500,000 (the "Minimum Offering") and CAD$8,000,000 (the "Maximum Offering"), respectively.

The Proposed Offering and the Private Placement are intended to provide a comprehensive financing package to fund the Corporation's operations until December 31, 2017, through the completion of the manufacturing scale-up and planning for the Phase 3 clinical trial for the continued development of CaPre® (omega-3 phospholipid), Acasti's lead product candidate, and, if the Maximum Offering is completed, through the initiation of the Phase 3 clinical trial, and, as such, the completion of the Proposed Offering and the Private Placement are conditional upon each other. Net proceeds from the Proposed Offering and the Private Placement are also planned to be used for intellectual property expansion, business development activities, general and administrative expenses, and working capital.

Each of the Proposed Offering and the Private Placement is subject to certain conditions including, but not limited to, the receipt of all necessary approvals, including the acceptance of the TSXV. There can be no assurance as to whether or when the Proposed Offering and Private Placement may be completed, or as to the actual size or terms of the Proposed Offering or Private Placement.

There will not be any sale or any acceptance of an offer to buy the Units until a receipt for the final short form prospectus has been issued.
