Harvest One Cannabis Inc. (TSXV:HVST) ("Harvest One" or the "Company") is pleased to announce that is has entered into a revised engagement letter with Mackie Research Capital Corporation (as the lead underwriter and sole bookrunner), on behalf of a syndicate of Underwriters, including Haywood Securities Inc., and Eight Capital (collectively, the "Underwriters") to increase the size of the previously announced bought short form prospectus offering to 17,500 convertible debenture units of the Company (the "Debenture Units") at a price of $1,000 per Debenture Unit (the "Offering Price"), for aggregate gross proceeds of $17,500,000 (the "Offering").

The Company has also granted the Underwriters an option (the "Over-Allotment Option") exercisable in whole or in part, at any time up to 30 days after the closing of the Offering to purchase up to an additional 2,625 Debenture Units at the Offering Price. If the Over-Allotment Option is exercised in its entirety, the aggregate gross proceeds of the Offering will be $20,125,000.

Under the Offering each Debenture Unit will consist of $1,000 principal amount of 8.0% unsecured convertible debentures of the Company (the "Convertible Debentures") and 458 common share purchase warrants of the Company (the "Warrants").

The Convertible Debentures will bear interest from the date of closing at 8.0% per annum, payable semiannually on June 30 and December 31 of each year and will mature 5 years from the date the Debenture Units are issued (the "Maturity Date"). The Convertible Debentures will be convertible at the option of the holder into common shares of the Company ("Common Shares") at any time prior to the close of business on the Maturity Date at a conversion price of $0.84 per share (the "Conversion Price"). The Company may force the conversion of the principal amount of the then outstanding Convertible Debentures at the Conversion Price on not more than 60 days' and not less than 30 days' notice should the daily volume weighted average trading price of the Common Shares be greater than $1.40 for the consecutive 30 trading days preceding the notice.

Upon a change of control of the Company, holders of the Convertible Debentures will have the right to require the Company to repurchase their Convertible Debentures, in whole or in part, on the date that is 30 days following the giving of notice of the change of control, at a price equal to 104% of the principal amount of the Convertible Debentures then outstanding, plus accrued and unpaid interest thereon (the "Offer Price"). If 90% or more of the principal amount of the Convertible Debentures outstanding on the date of the notice of the change of control have been tendered for redemption, the Company will have the right to redeem all of the remaining Convertible Debentures at the Offer Price.

Each Warrant entitles the holder thereof to acquire one Common Share for an exercise price equal to $1.09 at any time up to 36 months following the closing of the Offering (subject to adjustment in certain customary events). Provided that if, at any time prior to the expiry date of the Warrants, the closing price of the Common Shares on the TSX Venture Exchange equals or exceeds $1.64 for 10 consecutive trading days, the Company may, within 15 days of the occurrence of such event, deliver a notice to the holders of Warrants accelerating the expiry date of the Warrants to the date that is 30 days following the date of such notice (the "Accelerated Exercise Period"). Any unexercised Warrants shall automatically expire at the end of the Accelerated Exercise Period.

The Company intends to use the net proceeds of the Offering for working capital and general corporate purposes. Closing of the Offering is expected to occur on or about December 11, 2017. The Offering is subject to certain conditions including, but not limited to, the receipt of all necessary regulatory and stock exchange approvals, including the approval of the TSX Venture Exchange.

The Debenture Units will be offered by way of a short-form prospectus to be filed in those provinces of Canada (other than Québec) as the Underwriters may designate, pursuant to National Instrument 44-101 ? Short Form Prospectus Distributions and, may be offered in the United States on a private placement basis pursuant to appropriate exemptions from the registration requirements of the United States Securities Act of 1933, as amended.
