UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE OCTOBER ___, 2018.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, TRANSFERRED, HYPOTHECATED OR OTHERWISE TRADED ON OR THROUGH THE FACILITIES OF THE CANADIAN SECURITIES EXCHANGE OR OTHERWISE IN CANADA OR TO OR FOR THE BENEFIT OF A CANADIAN RESIDENT UNTIL OCTOBER ___, 2018 AND THEN ONLY IN ACCORDANCE WITH ALL APPLICABLE LAWS.

THE WARRANTS EVIDENCED HEREBY ARE EXERCISABLE AT OR BEFORE 5:00 P.M. (TORONTO TIME) ON JUNE ___, 2023 AFTER WHICH TIME THE WARRANTS EVIDENCED HEREBY SHALL BE DEEMED TO BE VOID AND OF NO FURTHER FORCE OR EFFECT.

THIS CERTIFIES that, for value received, ________ (the "Holder"), is the registered holder of ______ warrants (collectively, the "Warrants"; each a "Warrant"), each Warrant entitling the Holder, subject to the terms and conditions set forth in this Wa1rnnt Certificate (the "Certificate"), to purchase from TerrAscend Corp. (the "Corporation"), one common share in the capital of the Corporation (a "Common Share"), at any time, subject to the vesting conditions in subsection I (a) of this Warrant certificate, until 5:00 p.m. (Toronto time) on June 6, 2023, at which time the Warrants evidenced by this Certificate shall become wholly void and the unexercised portion of the subscription right represented hereby will expire and terminate (the "Time of Expiry"), on payment of a price per Common Share equal to CAD$_____ (the "Exercise Price"). The number of Common Shares which the Holder is entitled to acquire upon exercise of the Warrants and the Exercise Price are subject to adjustment as hereinafter provided.

The Holder shall be entitled to the rights evidenced by this Ce1tificate free from all equities and rights of set-off or counterclaim between the Corporation and the original or any interim holder and all persons may act accordingly and the receipt by the Holder of the Common Shares issuable upon exercise hereof shall be a good discharge to the Corporation.

(a)

Exercise. The Holder is entitled, from and after _______, 2019 to exercise one half of their Warrants, and after ________, 2020, exercise the remainder of their Warrants (the "Vesting Date"), to exercise the Warrants in whole or in part in tranches, at any time or from time to time on or prior to the Time of Expiry. The Corporation shall, on the next business day after receiving a duly executed Election to Purchase (as defined below) and the Exercise Price for the number of Common Shares specified in the Election to Purchase (the "Exercise Date"), issue that number of Common Shares specified in the Election to Purchase.

(c)

Election to Purchase. The rights evidenced by this Certificate may be exercised by the Holder in whole or in part and in accordance with the provisions hereof by delivery of an election to purchase in substantially the form attached hereto as Schedule I (the "Election to Purchase"), properly completed and executed, together with payment by wire transfer, certified cheque or bank draft of the Exercise Price for the number of Common Shares specified in the Election to Purchase, at the office of the Corporation at 3610 Mavis Road, Mississauga, Ontario, LSC I W2 or such other address in Canada as may be notified in writing by the Corporation (the "Corporation Office"). In the event that the rights evidenced by this Certificate are exercised in part, the Corporation shall, contemporaneously with the issuance of the Common Shares issuable on the exercise of the Warrants so exercised, issue to the Holder a Warrant Certificate on identical terms in respect of that number of Common Shares in respect of which the Holder has not exercised the rights evidenced by this Certificate.

(d)

Certificates and Electronic Deposits. As promptly as practicable after the Exercise Date (but no later than three business days after the Exercise Date), the Corporation shall, as specified by the Holder in the Election to Purchase, either (i) issue and deliver to the Holder, registered in the name of the Holder, a certificate for the number of Common Shares issuable on exercise of the Warrants so exercised and a Certificate representing the balance of any unexercised Warrants, or (ii) in the case of the Common Shares, issue and cause to be deposited electronically with CDS Clearing and Depository Services Inc. ("CDS") through the book-based system administered by CDS using the "non-certificated inventory" issue process that number of Common Shares issuable on exercise of the Warrants so exercised and, in the case of the Warrants, a Certificate representing the balance of any unexercised Warrants. To the extent permitted by law, such exercise shall be deemed to have been effected as of the close of business on the Exercise Date, and at such time the rights of the Holder with respect to the number of Warrants which have been exercised as such shall cease, and the Common Shares and any unexercised Warrants shall then be issuable upon such exercise as outlined above and the Holder shall be deemed to have become the holder of record of the Common Shares and unexercised Warrants represented thereby. Notwithstanding the above, all Common Shares issued to a United States institutional "accredited investor" as defined in Rule 50 I (a)(l ), (2), (3), or (7) of Regulation D under the U.S. Securities Act will be evidenced by physical certificates.

(any of such events in subsections l(t)(i)(A), (B) or (C) being called a "Common Share Reorganization") then, in each such event, the Exercise Price shall be adjusted as of the effective date or record date of such Common Share Reorganization, as the case may be, and shall, in the case of the events referred to in (A) or (C) above, be decreased in proportion to the number of outstanding Common Shares resulting from such subdivision, re-division, change or distribution, or shall, in the case of the events referred to in (B) above, be increased in proportion to the number of outstanding Common Shares resulting from such reduction, combination or consolidation by multiplying the Exercise Price in effect immediately prior to such effective date or record date by a fraction, the numerator of which shall be the number of Common Shares outstanding on such effective date or record date before giving effect to such Common Share Reorganization and the denominator of which shall be the number of Common Shares outstanding as of the effective date or record date after giving effect to such Common Share Reorganization (including, in the case where securities exchangeable for or convertible into Common Shares are distributed, the number of Common Shares that would have been outstanding had such securities been exchanged for or converted into Common Shares on such record date or effective date). Such adjustment shall be made successively whenever any event referred to in this subsection I (f)(i)shall occur. Upon any adjustment of the Exercise Price pursuant to subsection I (t)(i), the Exchange Rate (as defined below) shall be contemporaneously adjusted by multiplying the number of Common Shares theretofore obtainable on the exercise thereof by a fraction of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment and the denominator shall be the Exercise Price resulting from such adjustment. "Exchange Rate" means the number of Common Shares subject to the right of purchase under each Warrant, which, as of the date hereof, is one (I) Common Share for one (I) Warrant.

(ii)

If and whenever at any time during the Adjustment Period, the Corporation shall fix a record date for the issuance of rights, options or warrants to all or substantially all the holders of its outstanding Common Shares entitling them, for a period expiring not more than 45 days after such record date, to subscribe for or purchase Common Shares (or securities convertible or exchangeable into Common Shares) at a price per Common Share (or having a conversion or exchange price per Common Share) less than 95% of the Current Market Price (as defined below) on such record date (a "Rights Offering"), the Exercise Price shall be adjusted immediately after such record date so that it shall equal the amount determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of Common Shares outstanding on such record date plus a number of Common Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Common Shares offered for subscription or purchase (or the aggregate

conversion or exchange price of the convertible or exchangeable securities so offered) by the Current Market Price, and of which the denominator shall be the total number of Common Shares outstanding on such record date plus the total number of additional Common Shares offered for subscription or purchase or into which the convertible or exchangeable securities so offered are convertible or exchangeable. Any Common Shares owned by or held for the account of the Corporation shall be deemed not to be outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed. To the extent that no such rights or warrants are exercised prior to the expiration thereof, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed or, if any such rights or warrants are exercised, to the Exercise Price which would then be in effect based upon the number of Common Shares (or securities convertible or exchangeable into Common Shares) actually issued upon the exercise of such rights or warrants, as the case may be. Upon any adjustment of the Exercise Price pursuant to this subsection 1(f)(ii), the Exchange Rate will be adjusted immediately after such record date so that it will equal the rate determined by multiplying the Exchange Rate in effect on such record date by a fraction, of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment and the denominator shall be the Exercise Price resulting from such adjustment. Such adjustment will be made successively whenever such a record date is fixed, provided that if two or more such record dates or record dates referred to in this subsection 1 (f)(ii) are fixed within a period of 25 trading days, such adjustment will be made successively as if each of such record date occurred on the earliest of such record dates.

(iii)

If and whenever at any time during the Adjustment Period the Corporation shall fix a record date for the making of a distribution to all or substantially all the holders of its outstanding Common Shares of (i) securities of any class, whether of the Corporation or any other entity (other than Common Shares), (ii) rights, options or warrants to subscribe for or purchase Common Shares (or other securities convertible into or exchangeable for Common Shares), other than pursuant to a Rights Offering; (iii) evidences of its indebtedness or (iv) any cash, securities or other property or other assets (other than, if applicable, dividends paid in the ordinary course) and if such issue or distribution does not constitute a Common Share Reorganization, a Rights Offering or a distribution of Common Shares upon the exercise of Warrants or any outstanding options, then, in each such case, the Exercise Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of Common Shares outstanding on such record date multiplied by the Current Market Price on such record date, less the excess, if any, of the fair market value on such record date, as determined by the directors of the Corporation, acting reasonably (whose determination shall be conclusive, subject to stock exchange approval), of such cash, securities or other property or other assets so issued or distributed over the fair market value of any consideration received therefor by the Corporation from the holders of the Common Shares, and of which the denominator shall be the total number of Common Shares outstanding on such record date multiplied by the Current Market Price. Any Common Shares owned by or held for the account of the Corporation shall be deemed not to be outstanding for the purpose of any such computation. Such

adjustment shall be made successively whenever such a record date is fixed. To the extent that such distribution is not so made, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed. Upon any adjustment of the Exercise Price pursuant to this subsection 1(f)(iii), the Exchange Rate will be adjusted immediately after such record date so that it will equal the rate determined by multiplying the Exchange Rate in effect on such record date by a fraction, of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment and the denominator shall be the Exercise Price resulting from such adjustment. Such adjustment will be made successively whenever such a record date is fixed, provided that if two or more such record dates or record dates referred to in this subsection 1(f)(iii) are fixed within a period of 25 trading days, such adjustment will be made successively as if each of such record date occurred on the earliest of such record dates.

(iv)

If and whenever at any time during the Adjustment Period, there is a reclassification of the Common Shares or a capital reorganization of the Corporation other than as described in subsection 1(f)(i) or a consolidation, amalgamation, arrangement or merger of the Corporation with or into any other body corporate, trust, partnership or other entity, or a sale or conveyance of the property and assets of the Corporation as an entirety or substantially as an entirety to any other body corporate, trust, partnership or other entity (each, a "Change of Control"), any Holder that has not exercised its Warrants prior to the effective date of such Change of Control, upon the exercise of such Warrant thereafter, shall be entitled to receive upon payment of the Exercise Price and shall accept, in lieu of the number of Common Shares that prior to such effective date the Holder would have been entitled to receive, the number of shares or other securities or property of the Corporation or of the body corporate, trust, partnership or other entity resulting from such merger, amalgamation or consolidation, or to which such sale or conveyance may be made, as the case may be, that such Holder would have been entitled to receive on such Change of Control, if, on the effective date thereof, as the case may be, the Holder had been the registered holder of the number of Common Shares to which prior to such effective date it was entitled to acquire upon the exercise of the Warrants. If determined appropriate by the Corporation, relying on advice of legal counsel, to give effect to or to evidence the provisions of this subsection I (f)(iv), the Corporation, its successor, or such purchasing body corporate, partnership, trust or other entity, as the case may be, shall, prior to or contemporaneously with any such Change of Control, enter into an agreement or certificate which shall provide, to the extent possible, for the application of the provisions set forth in this Certificate with respect to the rights and interests thereafter of the Holder to the end that the provisions set forth in this Certificate shall thereafter correspondingly be made applicable, as nearly as may reasonably be, with respect to any shares, other securities or property to which the Holder is entitled on the exercise of its acquisition rights thereafter. Any agreement or certificate entered into between the Corporation, any successor to the Corporation or such purchasing body corporate, partnership, trust or other entity and the Holder shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this subsection I (f) and which shall apply to successive reclassifications, capital reorganizations, amalgamations, consolidations, mergers, sales or conveyances arrangements.

(v)

In any case in which this subsection 1(f) shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the Corporation may defer, until the occurrence of such event, issuing to the Holder of any Warrant exercised after the record date and prior to completion of such event the additional Common Shares issuable by reason of the adjustment required by such event before giving effect to such adjustment; provided, however, that the Corporation shall deliver to the Holder an appropriate instrument evidencing the Holder's right to receive such additional Common Shares upon the occurrence of the event requiring such adjustment and the right to receive any distributions made on such additional Common Shares declared in favour of holders of record of Common Shares on and after the relevant date of exercise or such later date as the Holder would, but for the provisions of this subsection 1(f)(v), have become the holder of record of such additional Common Shares pursuant to this subsection l(f).

(vi)

In any case in which subsection 1(f)(i)(C), subsection 1(f)(ii) or subsection l(f)(iii) require that an adjustment be made to the Exercise Price, no such adjustment shall be made if the Holder of the outstanding Warrants receives, subject to any required stock exchange or regulatory approval, the rights or warrants referred to in subsection 1(f)(i)(C), subsection 1(f)(ii) or the shares, rights, options, warrants, evidences of indebtedness or assets referred to in subsection 1(f)(iii), as the case may be, in such kind and number as they would have received if they had been holders of Common Shares on the applicable record date or effective date, as the case may be, by virtue of their outstanding Warrants having then been exercised into Common Shares at the Exercise Price in effect on the applicable record date or effective date, as the case may be.

(vii)

The adjustments provided for in this subsection 1(f) are cumulative, and shall, in the case of adjustments to the Exercise Price be computed to the nearest whole cent and shall apply to successive subdivisions, re- divisions, reductions, combinations, consolidations, distributions, issues or other events resulting in any adjustment under the provisions of this subsection 1(f), provided that, notwithstanding any other provision of this Section, no adjustment of the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Exercise Price then in effect or the number of Common Shares issuable upon the exercise of a Warrant by at least one one hundredth of a Common Share; provided, however, that any adjustments which by reason of this subsection 1(f)(vii) are not required to be made shall be carried forward and taken into account in any subsequent adjustment.

(viii)

After any adjustment pursuant to this subsection 1(f), the term "Common Shares", where used in this Certificate, shall be interpreted to mean securities of any class or classes which, as a result of such adjustment and all prior adjustments pursuant to this subsection 1(f), the Holder is entitled to receive upon the exercise of Warrants, and the number of Common Shares indicated by any exercise made pursuant to a Warrant shall be interpreted to mean the number of Common Shares or other property or securities the Holder is entitled to receive, as a result of such adjustment and all prior adjustments pursuant to this subsection 1(f), upon the full exercise of a Warrant.

(xi)

As a condition precedent to the taking of any action which would require an adjustment in any of the acquisition rights pursuant to any of the Warrants, including the number of Common Shares which are to be received upon the exercise thereof, the Corporation shall take any action which may, in the opinion of legal counsel, be necessary in order that the Corporation has unissued and reserved in its authorized capital and may validly and legally issue as fully paid and non-assessable all the Common Shares which the holders of such Warrants are entitled to receive on the full exercise thereof in accordance with the provisions hereof.

(xiii)

The Corporation covenants to and in favour of the Holder that so long as this Warrant remains outstanding, it will give notice to the Holder of the effective date or of its intention to fix a record date for any event referred to in this subsection l(f) whether or not such action would give rise to an adjustment in the Exercise Price or the number and type of securities issuable upon the exercise of the Warrants, and, in each case, such notice shall specify the particulars of such event and the record date and the effective date for such event; provided that the Corporation shall only be required to specify in such notice such particulars of such event as have been fixed and determined on the date on which such notice is given. Such notice shall be given not less than 14 days in each case prior to such applicable record date or effective date.

reasonable opinion of the directors of the Corporation would materially affect the rights of the Holder, the Exercise Price and/or the Exchange Rate, the number of Common Shares which may be acquired upon exercise of the Warrants shall be adjusted in such manner and at such time, by action of the directors, acting reasonably and in good faith, in their sole discretion as they may determine to be equitable to the Holder in the circumstances, provided that no such adjustment will be made unless any requisite prior approval of any stock exchange on which the Common Shares are listed for trading has been obtained.

(xvii)

If at any time a question or dispute arises with respect to adjustments provided for in this subsection I (f), such question or dispute will be conclusively determined by the auditor of the Corporation or, if they are unable or unwilling to act, by such other firm of independent chartered accountants as may be selected by action of the directors of the Corporation and any such determination, subject to regulatory approval and absent manifest error, will be binding upon the Corporation and the Holder. The Corporation will provide such auditor or chartered accountant with access to all necessary records of the Corporation.

(g)

Shares to be Reserved. The Corporation will at all times keep available and reserve out of its authorized Common Shares, solely for the purpose of issuing upon the exercise of the Warrants, such number of Common Shares as shall then be issuable upon the exercise of the Warrants. The Corporation covenants and agrees that all such Common Shares which shall be so issuable will, upon issuance and receipt of the Exercise Price therefor, be duly authorized and issued as fully paid and non assessable. The Corporation will take all such actions as may be necessary to ensure that all such Common Shares may be so issued without violation of any applicable requirements of any exchange upon which the Common Shares may be listed or in respect of which the Common Shares are qualified for unlisted trading privileges. The Corporation will take all such actions as are within its power to ensure that all such Common Shares may be so issued without violation of any applicable law.

(i)

Current Market Price. For the purposes of any computation hereunder, the "Current Market Price" at any date shall be the volume weighted average trading price per Common Share for the 20 consecutive trading days ending five (5) trading days prior to the relevant date on the most senior stock exchange in Canada on which the Common Shares may then be listed and on which there is the greatest volume of trading of the Common Shares for such 20 day period, or, if the Common Shares or any other security in respect of which a detennination of Current Market Price is being made are not listed on any stock exchange, which includes the Canadian Securities Exchange, the Current Market Price shall be determined in good faith by the directors of the Corporation, which determination shall be conclusive, absent fraud or manifest error. The volume weighted average trading price shall be determined by dividing the aggregate sale price of all such Common Shares sold on the said exchange during the said 20 consecutive trading days by the total number of such Common Shares so sold.

IN WITNESS WHEREOF the Corporation has caused this Certificate to be signed by a duly authorized officer.
