NEWS RELEASE

Pursuant to the Offering, the Corporation issued an aggregate principal amount of CDN$6,838,000 of Debentures at a price of CDN$1,000 per Debenture. The Debentures will mature on June 30, 2020 and bear interest at annual rate of 8% payable semi-annually on the last day of June and December of each year, commencing on December 31, 2017. The Debentures will be convertible at the option of the holders at any time prior to the close of business on the earlier of June 30, 2020 and the business day immediately preceding the date specified by the Corporation for redemption of Debentures. The conversion price will be CDN$1.35 (the "Conversion Price") per common share of the Corporation ("Share"), being a conversion rate of approximately 740 Shares per CDN$1,000 principal amount of Debentures, subject to adjustment in certain events.

The Debentures are not redeemable prior to June 30, 2018. On or after June 30, 2018, but prior to June 30, 2019, the Debentures may be redeemed at the Corporation's sole option, in whole or in part, from time to time on required prior notice at a redemption price equal to the principal amount of the Debentures, provided that the current market price on the date on which such notice of redemption is given is not less than 125% of the Conversion Price. On or after June 30, 2019 and prior to June 30, 2020, the Debentures may be redeemed at the Corporation's sole option, in whole or in part, from time to time on required prior notice, at a redemption price equal to the principal amount of the Debentures, irrespective of the current market price. In addition thereto, at the time of redemption, the Corporation will pay to the holder accrued and unpaid interest up to but not including the date of redemption.

The Debentures were distributed under a short form prospectus dated June 28, 2017 filed by the Corporation in connection with the Offering and available on SEDAR at www.sedar.com. The Offering was conducted, on a best efforts basis, by a syndicate of agents led by Desjardins Capital Markets and including Laurentian Bank Securities Inc. and Echelon Wealth Partners Inc. (collectively, the "Agents"). In consideration for the services rendered by the Agents, the Corporation has paid the Agents an agency fee of CDN$405,280.

The Debentures will commence trading on the TSX Venture Exchange today under the stock symbol IGX.DB.

The Corporation intends to use the aggregate net proceeds from the Offering for capital expansion, clinical studies, product development and general working capital requirements.

The Debentures and the common shares issuable upon conversion, redemption or maturity of the Debentures have been registered with the United States Securities and Exchange Commission pursuant to a Form S-1 Registration Statement that was declared effective on July 11, 2017 (the "Registration Statement").

Certain insiders of the Corporation participated in the Offering and purchased an aggregate of $120,000 principal amount of Debentures. Participation of insiders of the Corporation in the Offering constitutes a "related party transaction" as defined under Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"), but is exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 as neither the fair market value of securities being issued to insiders nor the consideration being paid by insiders exceeds 25% of the Corporation's market capitalization. None of the Corporation's directors has expressed any contrary views or disagreements with respect to the foregoing. The Corporation did not file a material change report 21 days prior to the closing of the Offering as the details of the participation of the insiders of the Corporation had not been confirmed at that time.
