EXHIBIT 99.1

FORM OF SERIES A COMMON SHARE PURCHASE WARRANT

AETERNA ZENTARIS INC.


Warrant Shares:		Issue Date: March , 2015

Warrant Number: W-		Initial Exercise Date: March , 2015

THIS SERIES A COMMON SHARE PURCHASE WARRANT (this “Warrant”) certifies that, for value received, (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after March , 2015 (the “Initial Exercise Date”) and on or prior to the close of business on the Termination Date (as defined below) but not thereafter, to subscribe for and purchase from Aeterna Zentaris Inc., a Canadian corporation (the “Corporation”), up to Common Shares (as defined below) (the “Warrant Shares”) of the capital of the Corporation. The purchase price of one Common Share under this Warrant shall be equal to the Exercise Price, as defined in Section 1(b) hereof. This Warrant is one of the Warrants (collectively, the “Warrants”) issued by the Corporation in connection with an offering of units pursuant to that certain Underwriting Agreement, dated March , 2015 (the “Subscription Date”), by and between the Corporation and the underwriter(s) named therein. Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 5.

Section 1. Exercise.

(a) Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Corporation (or such other office or agency of the Corporation as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Corporation) of a duly executed copy by facsimile or e-mail of the Notice of Exercise Form annexed hereto. No ink original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required. On or before the first Trading Day following the date on which the Corporation has received the Notice of Exercise Form (the date upon which the Corporation has received the Notice of Exercise Form, the “Exercise Date”), the Corporation shall transmit by facsimile or e-mail transmission an acknowledgment of confirmation of receipt of the Notice of Exercise Form to the Holder and the Corporation’s transfer agent for the Common Shares (the “Transfer Agent”). The Corporation shall deliver any objection to the Notice of Exercise Form on or before the end of the first Trading Day following the date on which the Corporation has received the Notice of Exercise Form. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Corporation until the Holder has purchased all of the Warrant Shares available hereunder and this Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Corporation for cancellation within three (3) Trading Days of the date the final Notice of Exercise Form is delivered to the Corporation. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in

- 2 -

an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Corporation shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time will be less than the amount stated on the face hereof.

(b) Exercise Price. The exercise price per Common Share under this Warrant shall be US$ , subject to adjustment hereunder (the “Exercise Price”).

(i) Notwithstanding anything contained herein to the contrary (other than Section 1(f) below), the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment of the Exercise Price otherwise contemplated to be made to the Corporation upon such exercise, elect instead to receive upon such exercise the “Net Number” of Common Shares determined according to the following formula (a “Cashless Exercise”):


		Net Number =		(A x B) – (A x C)
				D

For purposes of the foregoing formula:

A= the total number of shares with respect to which this Warrant is then being exercised.

B = the quotient of (x) the sum of the VWAP of the Common Shares of each of the five (5) Trading Days ending at the close of business on NASDAQ or, if NASDAQ is not the principal U.S. trading market for the Common Shares, then on the principal securities exchange or securities market in the U.S. on which the Common Shares are then traded, immediately prior to the time of exercise as set forth in the applicable Notice of Exercise, divided by (y) five (5).

C = the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

D = as applicable: (i) the Closing Sale Price of the Common Shares on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is (1) both executed and delivered pursuant to Section 1(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant to Section 1(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) the Bid Price of the Common Shares as of the time of the Holder’s execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter pursuant to Section 1(a) hereof, or (iii) the

- 3 -

Closing Sale Price of the Common Shares on the date of the applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant to Section 1(a) hereof after the close of “regular trading hours” on such Trading Day.

(ii) For purposes of Rule 144(d) promulgated under the 1933 Act, as in effect on the date hereof, it is intended that the Warrant Shares issued in a Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued pursuant to the Underwriting Agreement. If Warrant Shares are issued in a Cashless Exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the 1933 Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised. The Corporation agrees not to take any position contrary to this Section 1(c)(ii).

(d) Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of Warrant Shares to be issued pursuant to the terms hereof, the Corporation shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 4(f).

(e) Mechanics of Exercise.

(i) Share Delivery. On or before the end of the first Trading Day following the date on which the Corporation has received the Notice of Exercise Form and, provided, that, the Holder has paid in full the aggregate Exercise Price for the Warrants being exercised by wire transfer or cashier’s check drawn on a United States bank or pursuant to the Cashless Exercise procedure specified in Section 1(c) above (the “Share Delivery Date”), the Corporation shall, (X) provided that the Transfer Agent is participating in The Depository Trust Corporation (“DTC”) Fast Automated Securities Transfer Program (the “FAST Program”) and so long as the certificates therefor are not required to bear a legend regarding restriction on transferability (which includes, without limitation, any exercise of this Warrant pursuant to a Cashless Exercise), upon the request of the Holder, credit such aggregate number of Common Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system, or (Y), if the Transfer Agent is not participating in the FAST Program or if the certificates are required to bear a legend regarding restriction on transferability, issue and dispatch by overnight courier to the address as specified in the Notice of Exercise Form, a certificate, registered in the Corporation’s share register in the name of the Holder or its designee, representing the number of Common Shares to which the Holder is entitled pursuant to such exercise. The Warrant Shares shall be deemed to have been issued, and the Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date this Warrant has been properly exercised, with payment to the Corporation of the Exercise Price (or by Cashless Exercise), irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be. The Corporation shall pay any and all taxes and other expenses of the Corporation (including overnight delivery charges) that may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant; provided, however, that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the

- 4 -

Holder or an Affiliate thereof.

(ii) Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Corporation shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the balance of the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

(iii) Rescission Rights. If the Corporation fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 1(e)(d)(i) hereof by the Share Delivery Date, then the Holder will have the right to rescind such exercise.

(iv) Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if the Corporation fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to an exercise on or before the Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, Common Shares to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Corporation shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the Common Shares so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Corporation was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of this Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of Common Shares that would have been issued had the Corporation timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Shares having a total purchase price of US$11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Shares with an aggregate sale price giving rise to such purchase obligation of US$10,000, under clause (A) of the immediately preceding sentence the Corporation shall be required to pay the Holder US$1,000. Notwithstanding the foregoing, the Corporation shall not be required to make the payments set forth herein in the case of uncertificated Warrant Shares if the Holder fails to timely file a request with the DTC to receive such uncertificated Warrant Shares. The Holder shall provide the Corporation written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Corporation, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Corporation’s failure to timely deliver the Warrant Shares as required pursuant to the terms hereof.

- 5 -

(v) No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Corporation shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

(vi) Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Corporation, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Corporation may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.

(vii) Closing of Books. The Corporation will not close its shareholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

(f) Holder’s Exercise Limitations. The Corporation shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 1 hereof or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Person acting as a group together with the Holder or any of the Holder’s Affiliates), would beneficially own in excess of the Beneficial Ownership Limitation. For purposes of the foregoing sentence, the number of Common Shares beneficially owned by the Holder and its Affiliates shall include the number of Common Shares issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of Common Shares which would be issuable upon (i) exercise of the remaining, non-exercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or non-converted portion of any other securities of the Corporation (including, without limitation, any other Common Shares Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates. Except as set forth in the preceding sentence, for purposes of this Section 1(f), beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Corporation is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 1(f) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of

- 6 -

whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Corporation shall have no obligation to verify or confirm the accuracy of such determination and shall have no liability for exercises of this Warrant that are in non-compliance with the Beneficial Ownership Limitation. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 1(f), in determining the number of outstanding Common Shares, a Holder may rely on the number of outstanding Common Shares as reflected in (A) the Corporation’s most recent audited annual or unaudited interim consolidated financial statements and/or accompanying management’s discussion and analysis filed with or furnished to the U.S. Securities and Exchange Commission (the “Commission”), as the case may be, (B) a more recent public announcement by the Corporation or (C) a more recent written notice by the Corporation or the Transfer Agent setting forth the number of Common Shares outstanding. Upon the written or oral request of a Holder, the Corporation shall within one Trading Day confirm orally and in writing to the Holder the number of Common Shares then outstanding as established by (A), (B) or (C) above, as applicable. In any case, the number of outstanding Common Shares shall be determined after giving effect to the conversion or exercise of securities of the Corporation, including this Warrant, by the Holder or its Affiliates since the date as of which such number of outstanding shares of Common Shares was reported. The “Beneficial Ownership Limitation” shall initially be 9.99% of the number of Common Shares outstanding immediately after giving effect to the issuance of Common Shares issuable upon exercise of this Warrant (or such lower percentage as otherwise requested by the Holder in writing on or prior to the Subscription Date). At any time the Holder may increase or decrease the Beneficial Ownership Limitation to any other percentage not in excess of 9.99% as specified in a written notice by the Holder to the Corporation; provided that (i) any such increase will not be effective until the 61st day after such notice is delivered to the Corporation, and (ii) any such increase or decrease will apply only to the Holder sending such notice and not to any other holder of Warrants. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(f) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant. If any Common Shares are delivered to a Holder (or its designee) in violation of this Section 1(f) as a result of an error or omission made or committed by or the inadvertence of the Holder (including in connection with any breach or inaccuracy of the Holder’s representation provided in Item 3 of the Notice of Exercise, the Corporation shall, to the extent permitted by the Canada Business Corporations Act and only if no issuer bid or issuer tender offer rules would in any way apply thereto, use its commercially reasonable efforts to have the Corporation’s registrar and transfer agent unwind such issuance and cancel such Common Shares, with the Holder having the right thereafter to either (x) cancel, in whole or in part, such Exercise Notice, as applicable, with respect to the issuance of such amount in excess of the Beneficial Ownership Limitation at such time (after which such amount shall be eligible to be exercised hereunder) or (y) require the issuance of such amount in excess of the Beneficial Ownership Limitation at such time, if ever, as its Cashless Exercise would not result in the Holder exceeding the Beneficial Ownership Limitation. For the avoidance of doubt, the obligation of the Corporation to issue and deliver such shares pursuant to clause (y) above shall survive the expiration of this Warrant.

Section 2. Certain Adjustments.

(a) Adjustment Upon Issuance of Common Shares. If and whenever on or after the Subscription Date, the Corporation issues or sells, or in accordance with this Section 2 is deemed to have issued or sold, any Common Shares (including the issuance or sale of Common Shares owned or held by or for the account of the Corporation, but excluding any Excluded Securities issued or sold or deemed to have been issued or sold) for a consideration per share (the “New Issuance Price”) less than a price equal to the Exercise Price in effect immediately prior to such issuance or sale or deemed issuance or sale (such Exercise Price then in effect is referred to as the “Applicable Price”) (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance, the Exercise Price then in effect shall be reduced to an amount equal to the New Issuance Price. For all purposes of the foregoing

- 7 -

(including, without limitation, determining the adjusted Exercise Price and the New Issuance Price under this Section 2(a)), the following shall be applicable:

(i) Issuance of Options. If the Corporation in any manner grants or sells any Options and the lowest price per share for which one Common Share is at any time issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable Price, then such Common Share shall be deemed to be outstanding and to have been issued and sold by the Corporation at the time of the granting or sale of such Option for such price per share. For purposes of this Section 2(a)(i), the “lowest price per share for which one Common Share is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Corporation with respect to any one Common Share upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option and (y) the lowest exercise price set forth in such Option for which one Common Share is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option minus (2) the sum of all amounts paid or payable to the holder of such Option (or any other Person) upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Option (or any other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance of such Common Shares or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Shares upon conversion, exercise or exchange of such Convertible Securities.

(ii) Issuance of Convertible Securities. If the Corporation in any manner issues or sells any Convertible Securities and the lowest price per share for which one Common Share is at any time issuable upon the conversion, exercise or exchange thereof is less than the Applicable Price, then such Common Share shall be deemed to be outstanding and to have been issued and sold by the Corporation at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 2(a)(ii), the “lowest price per share for which one Common Share is issuable upon the conversion, exercise or exchange thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Corporation with respect to one Common Share upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security and (y) the lowest conversion price set forth in such Convertible Security for which one Common Share is issuable upon conversion, exercise or exchange thereof minus (2) the sum of all amounts paid or payable to the holder of such Convertible Security (or any other Person) upon the issuance or sale of such Convertible Security plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Convertible Security (or any

- 8 -

other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance of such Common Shares upon conversion, exercise or exchange of such Convertible Securities, and if any such issuance or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made pursuant to other provisions of this Section 2(a), except as contemplated below, no further adjustment of the Exercise Price shall be made by reason of such issuance or sale.

(iii) Change in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exercisable or exchangeable for Common Shares increases or decreases at any time, the Exercise Price in effect at the time of such increase or decrease shall be adjusted to the Exercise Price which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 2(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are increased or decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Shares deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 2(a) shall be made if such adjustment would result in an increase of the Exercise Price then in effect.

(iv) Calculation of Consideration Received. If any Option and/or Convertible Security and/or Adjustment Right is issued in connection with the issuance or sale or deemed issuance or sale of any other securities of the Corporation (as determined by the Holder, the “Primary Security”, and such Option and/or Convertible Security and/or Adjustment Right, the “Secondary Securities”, and together with the Primary Security, each a “Unit”), together comprising one integrated transaction, the aggregate consideration per Common Share with respect to such Primary Security shall be deemed to be the lower of (x) the purchase price of such Unit, (y) if such Primary Security is an Option and/or Convertible Security, the lowest price per share for which one Common Share is at any time issuable upon the exercise or conversion of the Primary Security in accordance with Section 2(a)(i) and 2(a)(ii) above and (z) the VWAP of the Common Shares as of the Trading Day immediately following the public announcement of such Dilutive Issuance. If any Common Shares, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount of consideration received by the Corporation therefor. If any Common Shares, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by the Corporation will be the fair value of such consideration, except where such consideration consists of publicly traded securities, in which case the amount of consideration received by the Corporation for such securities will be the arithmetic average of the VWAPs of such security for each of the five (5) Trading Days immediately preceding the date of

- 9 -

receipt. If any Common Shares, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Corporation is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such Common Shares, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or publicly traded securities will be determined jointly by the Corporation and the Holder. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Trading Days after the tenth (10^th) day following such Valuation Event by an independent, reputable appraiser jointly selected by the Corporation and the Holder. The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Corporation.

(v) Record Date. If the Corporation takes a record of the holders of Common Shares for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Shares, Options or in Convertible Securities or (B) to subscribe for or purchase Common Shares, Options or Convertible Securities, then such record date will be deemed to be the date of the issuance or sale of the Common Shares deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase (as the case may be).

(b) Stock Dividends and Splits. Without limiting any provision of Section 2, if the Corporation, at any time on or after the Subscription Date, (i) pays a share dividend on one or more classes of its then outstanding Common Shares or otherwise makes a distribution on any class of share capital that is payable in Common Shares, (ii) subdivides (by any share split, share dividend, recapitalization or otherwise) one or more classes of its then outstanding Common Shares into a larger number of shares or (iii) combines (by combination, reverse share split or otherwise) one or more classes of its then outstanding Common Shares into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of Common Shares outstanding immediately before such event and of which the denominator shall be the number of Common Shares outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise Price shall be adjusted appropriately to reflect such event. Any adjustment made pursuant to this Section 2(b) shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination, consolidation or re-classification.

(c) Holder’s Right of Alternative Exercise Price Following Issuance of Certain Options or Convertible Securities. In addition to and not in limitation of the other provisions

- 10 -

of this Section 2, if the Corporation in any manner issues or sells or enters into any agreement to issue or sell, any Common Shares, Options or Convertible Securities (any such securities, “Variable Price Securities”) after the Subscription Date that are convertible into or exchangeable or exercisable for Common Shares at a price which varies or may vary with the market price of the Common Shares, including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting customary anti-dilution provisions (such as share splits, share combinations, share dividends and similar transactions) (each of the formulations for such variable price being herein referred to as, the “Variable Price”), the Corporation shall provide written notice thereof via facsimile and overnight courier to the Holder on the date of issuance of such Convertible Securities or Options. From and after the date the Corporation issues any such Convertible Securities or Options with a Variable Price, the Holder shall have the right, but not the obligation, in its sole discretion to substitute the Variable Price for the Exercise Price upon exercise of this Warrant by designating in the Notice of Exercise delivered upon any exercise of this Warrant that solely for purposes of such exercise the Holder is relying on the Variable Price rather than the Exercise Price then in effect. The Holder’s election to rely on a Variable Price for a particular exercise of this Warrant shall not obligate the Holder to rely on a Variable Price for any future exercises of this Warrant.

(d) Share Combination Event Adjustment. If at any time and from time to time on or after the Subscription Date there occurs any share split, share dividend, share combination recapitalization or other similar transaction involving the Common Shares (each, a “Share Combination Event”) and the product of (i) the quotient determined by dividing (x) the Exercise Price in effect immediately prior to the Share Combination Event by (y) the quotient determined by dividing (A) the sum of the VWAP of the Common Shares on each day of the fifteen (15) Trading Day period immediately prior to the Share Combination Event, divided by (B) fifteen (15); and (ii) the quotient determined by dividing (x) the sum of the VWAP of the Common Shares on each day of the fifteen (15) Trading Day period immediately following the date of such Share Combination Event, divided by (y) fifteen (15) (each, an “Event Market Price”) is less than the Exercise Price then in effect (after giving effect to the adjustment in clause (b) above), then on the sixteenth (16^th) Trading Day immediately following such Share Combination Event, the Exercise Price then in effect on such sixteenth (16^th) Trading Day (after giving effect to the adjustment in clause (b) above) shall be reduced (but in no event increased) to the Event Market Price. For the avoidance of doubt, if the adjustment in the immediately preceding sentence would otherwise result in an increase in the Exercise Price hereunder, no adjustment shall be made.

(e) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraph (b) of this Section 2, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained herein).

- 11 -

contemplated by the provisions of this Section 2 but not expressly provided for by such provisions (including, without limitation, the granting of share appreciation rights, phantom share rights or other rights with equity features), then the Corporation’s board of directors shall in good faith determine and implement an appropriate adjustment in the Exercise Price and the number of Warrant Shares (if applicable) so as to protect the rights of the Holder, provided that no such adjustment pursuant to this Section 2(f) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this Section 2, provided further that if the Holder does not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Corporation’s board of directors and the Holder shall agree, in good faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding absent manifest error and whose fees and expenses shall be borne by the Corporation.

(g) Voluntary Adjustment By Corporation. The Corporation may at any time during the term of this Warrant, with the prior written consent of the Holder and with the approval of the TSX, provided the Corporation shall at such time be an issuer listed on the TSX, reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Corporation.

(h) Pro Rata Distributions.

(i) In addition to any adjustments pursuant to Section 2, if at any time after the Subscription Date the Corporation grants, issues or sells any Options, Convertible Securities or rights to purchase shares, warrants, securities or other property pro rata to the record holders of any class of Common Shares (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of Common Shares acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Shares are to be determined for the grant, issuance or sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such Common Shares as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

- 12 -

Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of Common Shares acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of Common Shares are to be determined for the participation in such Distribution (provided, however, to the extent that the Holder’s right to participate in any such Distributions would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or the beneficial ownership of any such Common Shares as a result of such Distribution to such extent) and such Distribution to such extent shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

(i) Fundamental Transaction. The Corporation shall not enter into or be party to a Fundamental Transaction unless (i) the Successor Entity assumes in writing all of the obligations of the Corporation under this Warrant in accordance with the provisions of this Section 2(i) pursuant to written agreements in form and substance satisfactory to the Holder and approved by the Holder prior to such Fundamental Transaction, including agreements to deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, which is exercisable for a corresponding number of shares of share capital equivalent to the Common Shares acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of share capital (but taking into account the relative value of the Common Shares pursuant to such Fundamental Transaction and the value of such shares of share capital, such adjustments to the number of shares of share capital and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction) and (ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose Common Shares is quoted on or listed for trading on an Eligible Market. Upon the consummation of each Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of the applicable Fundamental Transaction, the provisions of this Warrant referring to the “Corporation” shall refer instead to the Successor Entity), and may exercise every right and power of the Corporation and shall assume all of the obligations of the Corporation under this Warrant with the same effect as if such Successor Entity had been named as the Corporation herein. Upon consummation of each Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction, in lieu of the Common Shares (or other securities, cash, assets or other property (except such items still issuable under Section 2(g) and (h) above, which shall continue to be receivable thereafter) issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction, such shares of publicly traded Common Shares (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant), as adjusted in accordance

- 13 -

with the provisions of this Warrant. Notwithstanding the foregoing, and without limiting Section 1(f) hereof, the Holder may elect, at its sole option, by delivery of written notice to the Corporation to waive this Section 2(i) to permit the Fundamental Transaction without the assumption of this Warrant. In addition to and not in substitution for any other rights hereunder, prior to the consummation of each Fundamental Transaction pursuant to which holders of Common Shares are entitled to receive securities or other assets with respect to or in exchange for Common Shares (a “Corporate Event”), the Corporation shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the Termination Date, in lieu of the shares of the Common Shares (or other securities, cash, assets or other property) issuable upon the exercise of this Warrant prior to such Fundamental Transaction, such shares, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant). Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Holder.

(j) Black Scholes Valuation. Notwithstanding the foregoing and the provisions of Section 2(i) above, at the request of the Holder delivered at any time commencing on the earliest to occur of (x) the public disclosure of any Fundamental Transaction, (y) the consummation of any Fundamental Transaction and (z) the Holder first becoming aware of any Fundamental Transaction (including, without limitation, a Fundamental Transaction that is publicly disclosed, consummated or of which the Holder first becomes aware (as the case may be) prior to the Initial Exercise Date) through the date that is ninety (90) days after the public disclosure of the consummation of such Fundamental Transaction by the Corporation pursuant to a Report of Foreign Issuer on Form 6-K filed with the Commission, the Corporation or the Successor Entity (as the case may be) shall purchase this Warrant from the Holder on the date of such request by paying to the Holder cash in an amount equal to the Black Scholes Value.

(k) Calculations. All calculations under this Section 2 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 2, the number of Common Shares deemed to be issued and outstanding as of a given date shall be the sum of the number of Common Shares issued and outstanding.

(l) Notice to Holder.

- 14 -

notice setting forth the Exercise Price after such adjustment and including a brief statement of the facts requiring such adjustment within three (3) Business Days of the end of the week in which one or more ATM Dilutive Issuances shall have occurred and the statement shall indicate the lowest price per Common Shares of all such ATM Dilutive Issuances effected during the applicable week.

(ii) Notice to Allow Exercise by Holder. If during the term in which this Warrant may be exercised by the Holder (A) the Corporation shall declare a dividend (or any other distribution in whatever form payable pro rata to all of the Corporation’s shareholders) on the Common Shares, (B) the Corporation shall declare a special non-recurring cash dividend on or a redemption of the Common Shares, (C) the Corporation shall authorize the granting to all holders of the Common Shares rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any shareholders of the Corporation shall be required in connection with any reclassification of the Common Shares, any consolidation or merger to which the Corporation is a party, any sale or transfer of all or substantially all of the assets of the Corporation, or any compulsory share exchange whereby the Common Shares are converted into other securities, cash or property, or (E) the Corporation shall authorize the voluntary or involuntary dissolution, liquidation or winding-up of the affairs of the Corporation, then, in each case, the Corporation shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register of the Corporation, at least twenty (20) calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Shares of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Shares of record shall be entitled to exchange their Common Shares for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. Without limiting the generality of the foregoing, the Corporation will give written notice to the Holder (i) immediately upon each adjustment of the Exercise Price and the number of Warrant Shares, setting forth in reasonable detail, and certifying, the calculation of such adjustment(s) and (ii) at least twenty (20) days prior to the date on which the Corporation closes its books or takes a record (A) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase shares, warrants, securities or other property to holders of Common Shares or (B) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in each case that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder and (iii) at least ten (10) Trading Days prior to the consummation of any Fundamental Transaction. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may

- 15 -

otherwise be expressly set forth herein. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Corporation or any of its Subsidiaries, the Corporation shall simultaneously file such notice with the Commission pursuant to a Report of Foreign Issuer on Form 6-K. It is expressly understood and agreed that the time of execution specified by the Holder in each Notice of Exercise shall be definitive and may not be disputed or challenged by the Corporation.

Section 3. Transfer of Warrant.

(a) Transferability. Subject to compliance with applicable securities laws, this Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Corporation or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Corporation shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled.

Subject to compliance with Section 3(a), as to any transfer which may be involved in such division or combination, the Corporation shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall include reference to the initial issue date set forth on the first page of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto and the Warrant number.

(c) Warrant Register. The Corporation shall register this Warrant, upon records to be maintained by the Corporation for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Corporation may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual written notice to the contrary.

Section 4. Miscellaneous.

(a) No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a shareholder of the Corporation prior to the exercise hereof except as otherwise set forth herein.

- 16 -

(b) Loss, Theft, Destruction or Mutilation of Warrant. The Corporation covenants that upon receipt by the Corporation of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any share certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it, and upon surrender and cancellation of such Warrant or share certificate, if mutilated, the Corporation will make and deliver a new Warrant or share certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or share certificate. Applicants for a replacement Warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable charges as the Corporation may prescribe.

(c) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

(d) Authorized Shares. The Corporation hereby represents and warrants to the Holder that its articles do not provide for any limit on the number of Common Shares that may be issued by the Corporation. The Corporation covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing share certificates to execute and issue the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Corporation will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Shares may be listed. The Corporation covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and non-assessable and free from all taxes, liens and charges created by the Corporation in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Except and to the extent as waived or consented to by the Holder, the Corporation shall not by any action, including, without limitation, amending its articles of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issuance or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Corporation will (i) take all such action as may be necessary or appropriate in order that the Corporation may validly and legally issue fully paid and non-assessable Warrant Shares upon the exercise of this Warrant and (ii) use reasonable best efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Corporation to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Corporation shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

- 17 -

(e) Governing Law. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. The Corporation hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall (i) be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Corporation in any other jurisdiction to collect on the Corporation’s obligations to the Holder or to enforce a judgment or other court ruling in favor of the Holder or (ii) limit, or be deemed to limit, any provision of Section 4(f). THE CORPORATION HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY.

(f) Dispute Resolution.

(i) In the case of a dispute relating to the Exercise Price, the Closing Sale Price, the Bid Price, Black Scholes Value or fair market value or the arithmetic calculation of the number of Warrant Shares (as the case may be) (including, without limitation, a dispute relating to the determination of any of the foregoing), the Corporation or the Holder (as the case may be) shall submit the dispute to the other party via facsimile (A) if by the Corporation, within two (2) Business Days after the occurrence of the circumstances giving rise to such dispute or (B) if by the Holder, at any time after the Holder learned of the circumstances giving rise to such dispute. If the Holder and the Corporation are unable to promptly resolve such dispute relating to such Exercise Price, such Closing Sale Price, such Bid Price, Black Scholes Value or such fair market value or such arithmetic calculation of the number of Warrant Shares (as the case may be), at any time after the second (2nd) Business Day following such initial notice by the Corporation or the Holder (as the case may be) of such dispute to the Corporation or the Holder (as the case may be), then the Holder may, at its sole option, select an independent, reputable investment bank to resolve such dispute.

- 18 -

(ii) The Holder and the Corporation shall each deliver to such investment bank (A) a copy of the initial dispute submission so delivered in accordance with the first sentence of Section 4(f)(i) and (B) written documentation supporting its position with respect to such dispute, in each case, no later than 5:00 p.m. (New York time) by the fifth (5^th) Business Day immediately following the date on which the Holder selected such investment bank (the “Dispute Submission Deadline”) (the documents referred to in the immediately preceding clauses (A) and (B) are collectively referred to herein as the “Required Dispute Documentation”) (it being understood and agreed that if either the Holder or the Corporation fails to so deliver all of the Required Dispute Documentation by the Dispute Submission Deadline, then the party who fails to so submit all of the Required Dispute Documentation shall no longer be entitled to (and hereby waives its right to) deliver or submit any written documentation or other support to such investment bank with respect to such dispute and such investment bank shall resolve such dispute based solely on the Required Dispute Documentation that was delivered to such investment bank prior to the Dispute Submission Deadline). Unless otherwise agreed to in writing by both the Corporation and the Holder or otherwise requested by such investment bank, neither the Corporation nor the Holder shall be entitled to deliver or submit any written documentation or other support to such investment bank in connection with such dispute (other than the Required Dispute Documentation).

(iii) The Corporation and the Holder shall cause such investment bank to determine the resolution of such dispute and notify the Corporation and the Holder of such resolution no later than ten (10) Business Days immediately following the Dispute Submission Deadline. The fees and expenses of such investment bank shall be borne solely by the Corporation, and such investment bank’s resolution of such dispute shall be final and binding upon all parties absent manifest error.

(iv) The Corporation expressly acknowledges and agrees that (i) this Section 4(f) constitutes an agreement to arbitrate between the Corporation and the Holder (and constitutes an arbitration agreement) under § 7501, et seq. of the New York Civil Practice Law and Rules (“CPLR”) and that each party is authorized to apply for an order to compel arbitration pursuant to CPLR § 7503(a) in order to compel compliance with this Section 4(f), (ii) a dispute relating to the Exercise Price includes, without limitation, disputes as to (A) whether an issuance or sale or deemed issuance or sale of Common Shares occurred under Section 2(a), (B) the consideration per share at which an issuance or deemed issuance of Common Shares occurred, (C) whether any issuance or sale or deemed issuance or sale of Common Shares was an issuance or sale or deemed issuance or sale of Excluded Securities, (D) whether an agreement, instrument, security or the like constitutes an Option or Convertible Security and (E) whether a Dilutive Issuance occurred, (iii) the terms of this Warrant shall serve as the basis for the selected investment bank’s resolution of the applicable dispute, such investment bank shall be entitled (and is hereby expressly authorized) to make all findings, determinations and the like that such investment bank determines are required to be made by such investment bank in connection with its resolution of such dispute (including, without limitation, determining (A) whether an issuance or sale or deemed issuance or sale of Common Shares occurred under Section 2(a), (B) the consideration per share at which an issuance or deemed issuance of Common Shares occurred, (C) whether any issuance or sale or deemed issuance or sale of Common Shares was an issuance or sale or

- 19 -

deemed issuance or sale of Excluded Securities, (D) whether an agreement, instrument, security or the like constitutes an Option or Convertible Security and (E) whether a Dilutive Issuance occurred) and in resolving such dispute such investment bank shall apply such findings, determinations and the like to the terms of this Warrant, (iv) the Holder (and only the Holder), in its sole discretion, shall have the right to submit any dispute described in this Section 4(f) to any state or federal court sitting in The City of New York, Borough of Manhattan in lieu of utilizing the procedures set forth in this Section 4(f) and (v) nothing in this Section 4(f) shall limit the Holder from obtaining any injunctive relief or other equitable remedies (including, without limitation, with respect to any matters described in this Section 4(f)).

(g) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder does not utilize Cashless Exercise, will have restrictions upon resale imposed by state and federal securities laws and Canadian securities laws.

(h) Non-waiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of the Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies.

(i) Notices. Unless otherwise provided, any notice required or permitted under this Warrant shall be given in writing and shall be deemed effectively given as hereinafter described (i) if given by personal delivery or e-mail, then such notice shall be deemed given upon such delivery, (ii) if given by telex or facsimile, then such notice shall be deemed given upon receipt of confirmation of complete transmittal, (iii) if given by mail, then such notice shall be deemed given upon the earlier of (A) receipt of such notice by the recipient or (B) three days after such notice is deposited in first class mail, postage prepaid, and (iv) if given by an internationally recognized overnight air courier, then such notice shall be deemed given one business day after delivery to such carrier. All notices shall be addressed as follows: if to the Corporation, at its principal executive office and, if to the Holder, at its address specified in the Warrant Register.

(j) Limitation of Liability. No provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of Holder for the purchase price of any Common Shares or as a shareholder of the Corporation, whether such liability is asserted by the Corporation or by creditors of the Corporation.

- 20 -

received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Corporation (or the performance thereof). The Corporation acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Corporation therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. The Corporation shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Corporation’s compliance with the terms and conditions of this Warrant (including, without limitation, compliance with Section 2 hereof). The issuance of shares and certificates for shares as contemplated hereby upon the exercise of this Warrant shall be made without charge to the Holder or such shares for any issuance tax or other costs in respect thereof, provided that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than the Holder or its agent on its behalf.

(l) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Corporation and the successors and permitted assigns of the Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

(m) Amendment. This Warrant may be modified or amended with the written consent of the Corporation and the Holder and with the approval of the TSX, provided the Corporation shall at such time be an issuer listed on the TSX. A Holder may also waive in writing a provision hereof in its favour or for its benefit. No consideration shall be offered or paid to the Holder to amend or consent to a waiver or modification of any provision of this Warrant unless the same consideration is also offered to all of the holders of the other Warrants.

(n) Severability. If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

(o) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

- 21 -

(p) Payment of Collection, Enforcement and Other Costs. If (a) this Warrant is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding or the holder otherwise takes action to collect amounts due under this Warrant or to enforce the provisions of this Warrant or (b) there occurs any bankruptcy, reorganization, receivership of the company or other proceedings affecting company creditors’ rights and involving a claim under this Warrant, then the Corporation shall pay the costs incurred by the Holder for such collection, enforcement or action or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, without limitation, reasonable attorneys’ fees and disbursements.

Notwithstanding anything contained herein to the contrary (other than Section 1(f) below), the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment of the Exercise Price otherwise contemplated to be made to the Corporation upon such exercise, elect instead to receive upon such exercise the “Net Number” of Common Shares determined according to the following formula (a “Cashless Exercise”):


Net Number =		(A x B) – (A x C)

(iii) For purposes of Rule 144(d) promulgated under the 1933 Act, as in effect on the date hereof, it is intended that the Warrant Shares issued in a Cashless Exercise or an Alternate Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued pursuant to the Underwriting Agreement.

The Warrant Shares shall be deemed to have been issued, and the Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date this Warrant has been properly exercised, with payment to the Corporation of the Exercise Price (or by Cashless Exercise or Alternate Cashless Exercise), irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be. The Corporation shall pay any and all taxes and other expenses of the Corporation (including overnight delivery charges) that may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant; provided, however, that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder or an Affiliate thereof.

- 5 -

- 6 -

(vii) Closing of Books. The Corporation will not close its shareholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

- 7 -

management’s discussion and analysis filed with or furnished to the U.S. Securities and Exchange Commission (the “Commission”), as the case may be, (B) a more recent public announcement by the Corporation or (C) a more recent written notice by the Corporation or the Transfer Agent setting forth the number of Common Shares outstanding. Upon the written or oral request of a Holder, the Corporation shall within one Trading Day confirm orally and in writing to the Holder the number of Common Shares then outstanding as established by (A), (B) or (C) above, as applicable. In any case, the number of outstanding Common Shares shall be determined after giving effect to the conversion or exercise of securities of the Corporation, including this Warrant, by the Holder or its Affiliates since the date as of which such number of outstanding shares of Common Shares was reported. The “Beneficial Ownership Limitation” shall initially be 9.99% of the number of Common Shares outstanding immediately after giving effect to the issuance of Common Shares issuable upon exercise of this Warrant (or such lower percentage as otherwise requested by the Holder in writing on or prior to the Subscription Date). At any time the Holder may increase or decrease the Beneficial Ownership Limitation to any other percentage not in excess of 9.99% as specified in a written notice by the Holder to the Corporation; provided that (i) any such increase will not be effective until the 61st day after such notice is delivered to the Corporation, and (ii) any such increase or decrease will apply only to the Holder sending such notice and not to any other holder of Warrants. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(f) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant. If any Common Shares are delivered to a Holder (or its designee) in violation of this Section 1(f) as a result of an error or omission made or committed by or the inadvertence of the Holder (including in connection with any breach or inaccuracy of the Holder’s representation provided in Item 3 of the Notice of Exercise, the Corporation shall, to the extent permitted by the Canada Business Corporations Act and only if no issuer bid or issuer tender offer rules would in any way apply thereto, use its commercially reasonable efforts to have the Corporation’s registrar and transfer agent unwind such issuance and cancel such Common Shares, with the Holder having the right thereafter to either (x) cancel, in whole or in part, such Exercise Notice, as applicable, with respect to the issuance of such amount in excess of the Beneficial Ownership Limitation at such time (after which such amount shall be eligible to be exercised hereunder) or (y) require the issuance of such amount in excess of the Beneficial Ownership Limitation at such time, if ever, as its Cashless Exercise or Alternate Cashless Exercise, as applicable, would not result in the Holder exceeding the Beneficial Ownership Limitation. For the avoidance of doubt, the obligation of the Corporation to issue and deliver such shares pursuant to clause (y) above shall survive the expiration of this Warrant.

- 8 -

Section 2. Certain Adjustments.

- 9 -

issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 2(a)(ii), the “lowest price per share for which one Common Share is issuable upon the conversion, exercise or exchange thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Corporation with respect to one Common Share upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security and (y) the lowest conversion price set forth in such Convertible Security for which one Common Share is issuable upon conversion, exercise or exchange thereof minus (2) the sum of all amounts paid or payable to the holder of such Convertible Security (or any other Person) upon the issuance or sale of such Convertible Security plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Convertible Security (or any other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance of such Common Shares upon conversion, exercise or exchange of such Convertible Securities, and if any such issuance or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made pursuant to other provisions of this Section 2(a), except as contemplated below, no further adjustment of the Exercise Price shall be made by reason of such issuance or sale.

- 10 -

or conversion of the Primary Security in accordance with Section 2(a)(i) and 2(a)(ii) above and (z) the VWAP of the Common Shares as of the Trading Day immediately following the public announcement of such Dilutive Issuance. If any Common Shares, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount of consideration received by the Corporation therefor. If any Common Shares, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by the Corporation will be the fair value of such consideration, except where such consideration consists of publicly traded securities, in which case the amount of consideration received by the Corporation for such securities will be the arithmetic average of the VWAPs of such security for each of the five (5) Trading Days immediately preceding the date of receipt. If any Common Shares, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Corporation is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such Common Shares, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or publicly traded securities will be determined jointly by the Corporation and the Holder. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Trading Days after the tenth (10^th) day following such Valuation Event by an independent, reputable appraiser jointly selected by the Corporation and the Holder. The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Corporation.

- 11 -

date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise Price shall be adjusted appropriately to reflect such event. Any adjustment made pursuant to this Section 2(b) shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination, consolidation or re-classification.

(c) Holder’s Right of Alternative Exercise Price Following Issuance of Certain Options or Convertible Securities. In addition to and not in limitation of the other provisions of this Section 2, if the Corporation in any manner issues or sells or enters into any agreement to issue or sell, any Common Shares, Options or Convertible Securities (any such securities, “Variable Price Securities”) after the Subscription Date that are convertible into or exchangeable or exercisable for Common Shares at a price which varies or may vary with the market price of the Common Shares, including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting customary anti-dilution provisions (such as share splits, share combinations, share dividends and similar transactions) (each of the formulations for such variable price being herein referred to as, the “Variable Price”), the Corporation shall provide written notice thereof via facsimile and overnight courier to the Holder on the date of issuance of such Convertible Securities or Options. From and after the date the Corporation issues any such Convertible Securities or Options with a Variable Price, the Holder shall have the right, but not the obligation, in its sole discretion to substitute the Variable Price for the Exercise Price upon exercise of this Warrant by designating in the Notice of Exercise delivered upon any exercise of this Warrant that solely for purposes of such exercise the Holder is relying on the Variable Price rather than the Exercise Price then in effect.

(e) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraph(b) of this Section 2, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained herein).

(f) Other Events. In the event that the Corporation (or any Subsidiary) shall take any action to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect the Holder from dilution or if any event occurs of the type contemplated by the provisions of this Section 2 but not expressly provided for by such provisions (including, without limitation, the granting of share appreciation rights, phantom share rights or other rights with equity features), then the Corporation’s board of directors shall in good faith determine and implement an appropriate adjustment in the Exercise Price and the number of Warrant Shares (if applicable) so as to protect the rights of the Holder, provided that no such adjustment pursuant to this Section 2(f) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this Section 2, provided further that if the Holder does not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then the Corporation’s board of directors and the Holder shall agree, in good faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding absent manifest error and whose fees and expenses shall be borne by the Corporation.

(h) Pro Rata Distributions.

extent (or beneficial ownership of such Common Shares as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

(ii) In addition to any adjustments pursuant to this Section 2, if the Corporation shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of Common Shares, by way of return of capital or otherwise (including, without limitation, any distribution of cash, shares or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the Subscription Date, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of Common Shares acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of Common Shares are to be determined for the participation in such Distribution (provided, however, to the extent that the Holder’s right to participate in any such Distributions would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or the beneficial ownership of any such Common Shares as a result of such Distribution to such extent) and such Distribution to such extent shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

- 14 -

Corporation under this Warrant with the same effect as if such Successor Entity had been named as the Corporation herein. Upon consummation of each Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction, in lieu of the Common Shares (or other securities, cash, assets or other property (except such items still issuable under Section 2(g) and (h) above, which shall continue to be receivable thereafter) issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction, such shares of publicly traded Common Shares (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant), as adjusted in accordance with the provisions of this Warrant. Notwithstanding the foregoing, and without limiting Section 1(f) hereof, the Holder may elect, at its sole option, by delivery of written notice to the Corporation to waive this Section 2(i) to permit the Fundamental Transaction without the assumption of this Warrant. In addition to and not in substitution for any other rights hereunder, prior to the consummation of each Fundamental Transaction pursuant to which holders of Common Shares are entitled to receive securities or other assets with respect to or in exchange for Common Shares (a “Corporate Event”), the Corporation shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the Termination Date, in lieu of the shares of the Common Shares (or other securities, cash, assets or other property) issuable upon the exercise of this Warrant prior to such Fundamental Transaction, such shares, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant). Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Holder.

(l) Notice to Holder.

(i) Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 2, the Corporation shall promptly mail to the Holder a notice setting forth the Exercise Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. In the case of a Dilutive Issuance comprised of Common Shares issued pursuant to any “At-the-Market” share issuance program currently in existence or implemented after the date hereof by the Corporation pursuant to a base shelf prospectus and corresponding registration statement and/or prospectus supplement thereto (an “ATM Dilutive Issuance”), then the Corporation shall only be required to send the aforementioned notice setting forth the Exercise Price after such adjustment and including a brief statement of the facts requiring such adjustment within three (3) Business Days of the end of the week in which one or more ATM Dilutive Issuances shall have occurred and the statement shall indicate the lowest price per Common Shares of all such ATM Dilutive Issuances effected during the applicable week.

The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Corporation or any of its Subsidiaries, the Corporation shall simultaneously file such notice with the Commission pursuant to a Report of Foreign Issuer on Form 6-K. It is expressly understood and agreed that the time of execution specified by the Holder in each Notice of Exercise shall be definitive and may not be disputed or challenged by the Corporation.

The Corporation acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Corporation therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. The Corporation shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Corporation’s compliance with the terms and conditions of this Warrant (including, without limitation, compliance with Section 2 hereof). The issuance of shares and certificates for shares as contemplated hereby upon the exercise of this Warrant shall be made without charge to the Holder or such shares for any issuance tax or other costs in respect thereof, provided that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than the Holder or its agent on its behalf.

Warrant Shares:		Issue Date: March , 2015

Warrant Number: W-		Initial Exercise Date: March , 2015

THIS SERIES C PRE-FUNDED COMMON SHARE WARRANT (this “Warrant”) certifies that, for value received, (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after March , 2015 (the “Initial Exercise Date”) and on or prior to the close of business on the Termination Date (as defined below) but not thereafter, to receive from Aeterna Zentaris Inc., a Canadian corporation (the “Corporation”), up to Common Shares (as defined below) (the “Warrant Shares”) of the capital of the Corporation. The purchase price of one Common Share under this Warrant shall be equal to the Exercise Price, as defined in Section 1(b) hereof; provided, that the Corporation hereby acknowledges and agrees that the Exercise Price has been prepaid by the Holder to the Corporation on or prior to the Issue Date. This Warrant is one of the Warrants (collectively, the “Warrants”) issued by the Corporation in connection with an offering of units pursuant to that certain Underwriting Agreement, dated March , 2015, (the “Subscription Date”) by and between the Corporation and the underwriter(s) named therein. Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 5.

Section 1. Exercise.

(a) Exercise of Warrant. Exercise of the rights to receive Warrant Shares represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Corporation (or such other office or agency of the Corporation as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Corporation) of a duly executed copy by facsimile or e-mail of the Notice of Exercise Form annexed hereto. No ink original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required. On or before the first Trading Day following the date on which the Corporation has received the Notice of Exercise Form (the date upon which the Corporation has received the Notice of Exercise Form, the “Exercise Date”), the Corporation shall transmit by facsimile or e-mail transmission an acknowledgment of confirmation of receipt of the Notice of Exercise Form to the Holder and the Corporation’s transfer agent for the Common Shares (the “Transfer Agent”).

Partial

- 2 -

exercises of this Warrant resulting in the exercise and issuance of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares available to be issued hereunder in an amount equal to the applicable number of Warrant Shares issued. The Holder and the Corporation shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the exercise and issuance of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for issuance hereunder at any given time will be less than the amount stated on the face hereof.

The Holder hereby acknowledges and agrees that the Holder shall not be entitled to the return or refund of all or any portion of the pre-paid Exercise Price under any circumstance or for any reason whatsoever, including in the event this Warrant shall not have been exercised prior to the Termination Date.

(c) 144 Status. For purposes of Rule 144(d) promulgated under the 1933 Act, as in effect on the date hereof, it is intended that the Warrant Shares issued hereunder shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued and the aggregate Exercise Price prepaid pursuant to the Underwriting Agreement. The parties acknowledge and agree that in accordance with Section 3(a)(9) of the 1933 Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised. The Corporation agrees not to take any position contrary to this Section 1(c).

(d) Disputes. In the case of a dispute as to the arithmetic calculation of the number of Warrant Shares to be issued pursuant to the terms hereof, the Corporation shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 4(f).

(e) Mechanics of Exercise.

(i) Share Delivery.

The Warrant Shares shall be deemed to have been issued, and the Holder or any other person so designated to be named therein shall be deemed to have become a holder

The Corporation shall pay any and all taxes and other expenses of the Corporation (including overnight delivery charges) that may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant; provided, however, that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder or an Affiliate thereof.

(ii) Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Corporation shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to receive the balance of the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

(iv) Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if the Corporation fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to an exercise on or before the Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, Common Shares to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Corporation shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total Exercise Price (including brokerage commissions, if any) for the Common Shares so exercised exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Corporation was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such issuance obligation was executed, and (B) at the option of the Holder, either reinstate the portion of this Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of Common Shares that would have been issued had the Corporation timely complied with its exercise and delivery obligations hereunder. For example, if the Holder exercises this Warrant into Common Shares having a total Exercise Price of US$11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Shares with an aggregate sale price giving rise to such issuance obligation of US$10,000, under clause (A) of the immediately preceding sentence the Corporation shall be required to pay the Holder US$1,000. Notwithstanding the foregoing, the Corporation shall not be required to make the

- 4 -

payments set forth herein in the case of uncertificated Warrant Shares if the Holder fails to timely file a request with the DTC to receive such uncertificated Warrant Shares. The Holder shall provide the Corporation written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Corporation, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Corporation’s failure to timely deliver the Warrant Shares as required pursuant to the terms hereof.

(vii) Closing of Books. The Corporation will not close its shareholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Corporation is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 1(f) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Corporation shall have no obligation to verify or confirm the accuracy of such determination and shall have no liability for exercises of this Warrant that are in non-compliance with the Beneficial Ownership Limitation. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 1(f), in determining the number of outstanding Common Shares, a Holder may rely on the number of outstanding Common Shares as reflected in (A) the Corporation’s most recent audited annual or unaudited interim consolidated financial statements and/or accompanying management’s discussion and analysis filed with or furnished to the U.S. Securities and Exchange Commission (the “Commission”), as the case may be, (B) a more recent public announcement by the Corporation or (C) a more recent written notice by the Corporation or the Transfer Agent setting forth the number of Common Shares outstanding. Upon the written or oral request of a Holder, the Corporation shall within one Trading Day confirm orally and in writing to the Holder the number of Common Shares then outstanding as established by (A), (B) or (C) above, as applicable. In any case, the number of outstanding Common Shares shall be determined after giving effect to the conversion or exercise of securities of the Corporation, including this Warrant, by the Holder or its Affiliates since the date as of which such number of outstanding shares of Common Shares was reported. The “Beneficial Ownership Limitation” shall initially be 9.99% of the number of Common Shares outstanding immediately after giving effect to the issuance of Common Shares issuable upon exercise of this Warrant (or such lower percentage as otherwise requested by the Holder in writing on or prior to the Subscription Date). At any time the Holder may increase or decrease the Beneficial Ownership Limitation to any other percentage not in excess of 9.99% as specified in a written notice by the Holder to the Corporation; provided that (i) any such increase will not be effective until the 61st day after such notice is delivered to the Corporation, and (ii) any such increase or decrease will apply only to the Holder sending such notice and not to any other holder of Warrants. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(f) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant. If any Common Shares are delivered to a Holder (or its designee) in violation of this Section 1(f) as a result of an error or omission made or committed by or the inadvertence of the Holder (including in connection with any breach or inaccuracy of the Holder’s representation provided in Item 3 of the Notice of Exercise, the Corporation shall, to the extent permitted by the Canada Business Corporations Act and only if no issuer bid or issuer tender offer rules would in any way apply thereto, use its commercially reasonable efforts to have the Corporation’s registrar and transfer agent unwind such issuance and cancel such Common Shares, with the Holder having the right thereafter to either (x) cancel, in whole or in part, such Exercise Notice, as applicable, with respect to the issuance of such amount in excess of the Beneficial Ownership Limitation at such time (after which such amount shall be eligible to be exercised hereunder) or (y) require the issuance of such amount in excess of the Beneficial Ownership Limitation at such time, if ever, as would not result in the Holder exceeding the Beneficial Ownership Limitation. For the avoidance of doubt, the obligation of the Corporation to issue and deliver such shares pursuant to clause (y) above shall survive the expiration of this Warrant.

Section 2. Certain Adjustments.

(a) Stock Dividends and Splits. Without limiting any provision of Section 2, if the Corporation, at any time on or after the Subscription Date, (i) pays a share dividend on one or more classes of its then outstanding Common Shares or otherwise makes a distribution on any class of share capital that is payable in Common Shares, (ii) subdivides (by any share split, share dividend, recapitalization or otherwise) one or more classes of its then outstanding Common Shares into a larger number of shares or (iii) combines (by combination, reverse share split or otherwise) one or more classes of its then outstanding Common Shares into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of Common Shares outstanding immediately before such event and of which the denominator shall be the number of Common Shares outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise Price shall be adjusted appropriately to reflect such event. Any adjustment made pursuant to this Section 2(b) shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination, consolidation or re-classification.

(b) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraph (a) of this Section 2, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained herein).

- 7 -

(d) Fundamental Transaction. Prior to the consummation of each Fundamental Transaction, the Corporation shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the Termination Date, in lieu of the shares of the Common Shares (or other securities, cash, assets or other property) issuable upon the exercise of this Warrant prior to such Fundamental Transaction, such shares, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant). Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Holder.

(e) Calculations. All calculations under this Section 2 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 2, the number of Common Shares deemed to be issued and outstanding as of a given date shall be the sum of the number of Common Shares issued and outstanding.

(f) Notice to Holder.

(i) Notice to Allow Exercise by Holder. If during the term in which this Warrant may be exercised by the Holder (A) the Corporation shall declare a dividend (or any other distribution in whatever form payable pro rata to all of the Corporation’s shareholders) on the Common Shares, (B) the Corporation shall declare a special non-recurring cash dividend on or a redemption of the Common

- 8 -

Shares, (C) the Corporation shall authorize the granting to all holders of the Common Shares rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any shareholders of the Corporation shall be required in connection with any reclassification of the Common Shares, any consolidation or merger to which the Corporation is a party, any sale or transfer of all or substantially all of the assets of the Corporation, or any compulsory share exchange whereby the Common Shares are converted into other securities, cash or property, or (E) the Corporation shall authorize the voluntary or involuntary dissolution, liquidation or winding-up of the affairs of the Corporation, then, in each case, the Corporation shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register of the Corporation, at least twenty (20) calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Shares of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Shares of record shall be entitled to exchange their Common Shares for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. Without limiting the generality of the foregoing, the Corporation will give written notice to the Holder (i) immediately upon each adjustment of the Exercise Price and the number of Warrant Shares, setting forth in reasonable detail, and certifying, the calculation of such adjustment(s) and (ii) at least twenty (20) days prior to the date on which the Corporation closes its books or takes a record (A) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase shares, warrants, securities or other property to holders of Common Shares or (B) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in each case that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder and (iii) at least ten (10) Trading Days prior to the consummation of any Fundamental Transaction. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Corporation or any of its Subsidiaries, the Corporation shall simultaneously file such notice with the Commission pursuant to a Report of Foreign Issuer on Form 6-K. It is expressly understood and agreed that the time of execution specified by the Holder in each Notice of Exercise shall be definitive and may not be disputed or challenged by the Corporation.

Section 3. Transfer of Warrant.

Section 4. Miscellaneous.

- 10 -

(d) Authorized Shares. The Corporation hereby represents and warrants to the Holder that its articles do not provide for any limit on the number of Common Shares that may be issued by the Corporation. The Corporation covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing share certificates to execute and issue the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Corporation will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Shares may be listed. The Corporation covenants that all Warrant Shares which may be issued upon the exercise of the rights to receive Warrant Shares represented by this Warrant will, upon exercise of the rights to receive Warrant Shares represented by this Warrant in accordance herewith, be duly authorized, validly issued, fully paid and non-assessable and free from all taxes, liens and charges created by the Corporation in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

- 11 -

dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall (i) be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Corporation in any other jurisdiction to collect on the Corporation’s obligations to the Holder or to enforce a judgment or other court ruling in favor of the Holder or (ii) limit, or be deemed to limit, any provision of Section 4(f). THE CORPORATION HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY.

(f) Dispute Resolution.

(i) In the case of a dispute relating to the Exercise Price or fair market value or the arithmetic calculation of the number of Warrant Shares (as the case may be) (including, without limitation, a dispute relating to the determination of any of the foregoing), the Corporation or the Holder (as the case may be) shall submit the dispute to the other party via facsimile (A) if by the Corporation, within two (2) Business Days after the occurrence of the circumstances giving rise to such dispute or (B) if by the Holder, at any time after the Holder learned of the circumstances giving rise to such dispute. If the Holder and the Corporation are unable to promptly resolve such dispute relating to such Exercise Price or such fair market value or such arithmetic calculation of the number of Warrant Shares (as the case may be), at any time after the second (2nd) Business Day following such initial notice by the Corporation or the Holder (as the case may be) of such dispute to the Corporation or the Holder (as the case may be), then the Holder may, at its sole option, select an independent, reputable investment bank to resolve such dispute.

- 12 -

Dispute Submission Deadline). Unless otherwise agreed to in writing by both the Corporation and the Holder or otherwise requested by such investment bank, neither the Corporation nor the Holder shall be entitled to deliver or submit any written documentation or other support to such investment bank in connection with such dispute (other than the Required Dispute Documentation).

(g) Non-waiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of the Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies.

(h) Notices. Unless otherwise provided, any notice required or permitted under this Warrant shall be given in writing and shall be deemed effectively given as hereinafter described (i) if given by personal delivery or e-mail, then such notice shall be deemed given upon such delivery, (ii) if given by telex or facsimile, then such notice shall be deemed given upon receipt of confirmation of complete transmittal, (iii) if given by mail, then such notice shall be deemed given upon the earlier of (A) receipt of such notice by the recipient or (B) three days after such notice is deposited in first class mail, postage prepaid, and (iv) if given by an internationally recognized overnight air courier, then such notice shall be deemed given one business day after delivery to such carrier. All notices shall be addressed as follows: if to the Corporation, at its principal executive office and, if to the Holder, at its address specified in the Warrant Register.

(i) Limitation of Liability. The aggregate Exercise Price of this Warrant has been fully paid on or prior to the Issue Date. No provision hereof shall give rise to any liability of Holder for the payment of any additional purchase price of any Common Shares (other than the Exercise Price of this Warrant paid on the Issue Date) or as a shareholder of the Corporation, whether such liability is asserted by the Corporation or by creditors of the Corporation.

- 13 -

(j) Remedies. The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder to pursue actual and consequential damages for any failure by the Corporation to comply with the terms of this Warrant. The Corporation covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, exercises and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Corporation (or the performance thereof). The Corporation acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Corporation therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. The Corporation shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Corporation’s compliance with the terms and conditions of this Warrant (including, without limitation, compliance with Section 2 hereof). The issuance of shares and certificates for shares as contemplated hereby upon the exercise of this Warrant shall be made without charge to the Holder or such shares for any issuance tax or other costs in respect thereof, provided that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than the Holder or its agent on its behalf.

(k) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Corporation and the successors and permitted assigns of the Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

(l) Amendment. This Warrant may be modified or amended with the written consent of the Corporation and the Holder and with the approval of the TSX, provided the Corporation shall at such time be an issuer listed on the TSX. A Holder may also waive in writing a provision hereof in its favour or for its benefit. No consideration shall be offered or paid to the Holder to amend or consent to a waiver or modification of any provision of this Warrant unless the same consideration is also offered to all of the holders of the other Warrants.

(m) Severability. If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof

- 14 -

and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

(n) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

(o) Payment of Collection, Enforcement and Other Costs. If (a) this Warrant is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding or the holder otherwise takes action to collect amounts due under this Warrant or to enforce the provisions of this Warrant or (b) there occurs any bankruptcy, reorganization, receivership of the company or other proceedings affecting company creditors’ rights and involving a claim under this Warrant, then the Corporation shall pay the costs incurred by the Holder for such collection, enforcement or action or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, without limitation, reasonable attorneys’ fees and disbursements.
