Each Unit consists of one (1) common share in the capital of the Company (each, a “Common Share”) and one-half (1/2) of one Common Share purchase warrant (each whole warrant, a “Warrant”). Each Warrant is exercisable into one (1) Common Share (each, a “Warrant Share”) at a price of $1.30 per Warrant Share for a period of two (2) years from closing, subject to an acceleration right (the “Acceleration Right”). Pursuant to the Acceleration Right, if the Common Shares have a closing price on the Canadian Securities Exchange (the “CSE”) (or such other securities exchange on which the Common Shares may be traded at such time) of $1.60 or greater per Common Share for a period of ten (10) consecutive trading days at any time after the issuance of the Warrants, then the Company may accelerate the expiry date of the Warrants by giving notice to the holders thereof (by disseminating a news release advising of the acceleration of the expiry date of the Warrants) and, in such case, the Warrants will expire on the thirtieth (30th) day after the date of such notice.

The Company paid an aggregate of $119,614.67 in cash and 128,617 finder’s warrants (the “Finder’s Warrants”) to Canaccord Genuity Corp., Echelon Wealth Partners Inc., PI Financial Corp., and Research Capital Corp.

The Company intends to use the net proceeds from the LIFE Offering to fund their research and development of the Company’s chemical recycling technologies and for general administrative and working capital expenses.

The Units were sold to purchasers resident in Canada and other qualifying jurisdictions pursuant to the listed issuer financing exemption under Part 5A of National Instrument 45-106 – Prospectus Exemptions (the “Listed Issuer Financing Exemption”). Since the Offering was completed pursuant to the Listed Issuer Financing Exemption, the securities issued in the Offering will not be subject to a hold period pursuant to applicable Canadian securities laws.
