1.2 Interpretation. References to the “Obligors” shall be interpreted as referring to “the Obligors or either of them”. References to “Articles,” “Sections,” “Exhibits,” and “Schedules” are to articles, sections, exhibits and schedules herein and hereto unless otherwise indicated. “Hereof,” “herein” and “hereunder” refer to this Agreement as a whole. “Including” is not limiting. All accounting and financial computations shall be computed in accordance with generally accepted accounting principles in Canada consistently applied (“GAAP”) including, for the avoidance of doubt, International Financial Reporting Standards. “Or” is not necessarily exclusive. All interest computation shall be based on a 360-day year and actual days elapsed prior to the Loan Commencement Date and on a 360-day year and 30 day month on and after the Loan Commencement Date.

1.3 Interest Act. For the purpose of the Interest Act (Canada) and disclosure thereunder, as well as under each Note, (i) whenever interest to be paid under any Loan Document is to be calculated on the basis of a 360-day year or any other period of time that is less than a calendar year, the yearly rate of interest to which the rate determined pursuant to such calculation is equivalent is the rate so determined multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by either 360 days or such other period of time, as the case may be, (ii) the principle of deemed reinvestment of interest shall not apply to any interest calculation under any Loan Document, and (iii) the rates of interest stipulated in any Loan Document are intended to be nominal rates and not effective rates or yields.

1.4 Usury. The Obligors and the Lender intend to comply with applicable law relating to usury. Notwithstanding any other provision of this Agreement or any other Loan Document, in no event shall any Loan Document require the payment or permit the collection of interest or other amounts in an amount or at a rate in excess of the amount or rate that is permitted by applicable law or in

an amount or at a rate that would result in the receipt by the Lender of interest at a criminal rate, as the terms “interest” and “criminal rate” are defined under the Criminal Code (Canada). Where more than one applicable law applies to the Obligors, the Obligors shall not be obliged to make payment in an amount or at a rate higher than the lowest permitted amount or rate. If from any circumstance whatever, fulfilment of any provision of any Loan Document would result in exceeding the highest rate or amount permitted by applicable law for the collection or charging of interest, the obligation to be fulfilled shall be reduced to reflect the highest permitted rate or amount. If from any circumstance the Lender shall ever receive anything of value as interest or deemed interest under any Loan Document that would result in exceeding the highest lawful rate or amount of interest permitted by applicable law, the amount that would be excessive interest shall be applied to the reduction of the principal amount of the relevant Loan, and not to the payment of interest, or if the excessive interest exceeds the unpaid principal balance of the relevant Loan, the amount exceeding the unpaid balance shall be refunded to the Obligors. In determining whether or not the interest paid or payable under any specified contingency exceeds the highest lawful rate, the Obligors and the Lender shall, to the maximum extent permitted by applicable law, (i) characterize any non principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and their effects, (iii) amortize, prorate, allocate and spread the total amount of interest throughout the term of the applicable Loan so that interest does not exceed the maximum amount permitted by applicable law, and/or (iv) allocate interest between portions of the Obligations to the end that no portion shall bear interest at a rate greater than that permitted by applicable law.

2. THE LOANS

2.1 Commitment. Subject to the terms hereof, Lender will make Advances to Borrower up to the principal amount of the Commitment, on or before the Commitment Termination Date. Notwithstanding anything in the Loan Documents to the contrary, Lender’s obligation to make any Advances or to lend the undisbursed portion of the Commitment shall terminate on the Commitment Termination Date. Repaid principal of the Advances may not be re-borrowed.

2.2 The Advances. A Note setting forth the specific terms of repayment will evidence each Advance. No Advance will be made for less than US $1,000,000, unless less than US $1,000,000 remains available under the Commitment for borrowing. Absence of a Note evidencing any portion of the Loan shall not impair Borrower’s obligation to repay it to Lender.

2.3 Terms of Payment, Repayment.

(a) Repayment. Borrower shall repay the principal and pay interest on each Advance on the terms set forth in the applicable Note. Amounts not paid when due hereunder or under the Note shall bear interest at the Default Rate.

(c) Default Rate. While an Event of Default has occurred and is continuing, interest on the Loan shall be increased to the Default Rate. Lender’s failure to charge or accrue interest at the Default Rate during the existence of an Event of Default shall not be deemed a waiver by Lender of its right or claim thereto or for future Events of Default.

(d) Date. Whenever any payment due under the Loan Documents is due on a day other than a business day, such payment shall be made on the next succeeding business day, and such extension of time shall be included in the computation of interest or fees, as the case may be.

or to confirm or protect the hypothec hereby constituted, including necessary inscriptions for the registration, renewal, carrying over or conservation of the hypothec and notices to third parties.

9.7 If any clause in this Agreement, or part thereof, is null or otherwise unenforceable, without effect, or deemed unwritten, the remaining provisions shall continue in full force and effect.

9.8 In the event of any conflict or inconsistency between the terms hereof and those contained in the Loan Agreement, the terms of the Loan Agreement shall prevail to the extent of such conflict or inconsistency, except if the result of such conflict resolution would render the hypothecs created herein invalid or unenforceable.

X=Y(A-B)

where:	X=	the number of Preferred Shares to be issued to the Holder pursuant to this Section 4.

	Y =	the number of Preferred Shares covered by this Warrant in respect of which the net issue election is made pursuant to this Section 4.

	A =	the Fair Market Value (defined below) of one Preferred Share, as determined at the time the net issue election is made pursuant to this Section 4.

	B =	the Purchase Price in effect under this Warrant at the time the net issue election is made pursuant to this Section 4.

“Fair Market Value” of a Preferred Share (or fully paid and nonassessable shares of the Company’s Class A Common Shares (the “Common Shares”) if the Preferred Shares have been automatically converted into Common Shares) as of the date that the net issue election is made (the “Determination Date”) shall mean:

(i) If the net issue election is made in connection with and contingent upon the closing of the sale of the Common Shares to the public in a public offering pursuant to a prospectus filed with Canadian securities regulators or an equivalent United States registration (a “Public Offering”), and if the Company’s prospectus relating to such Public Offering (“Prospectus”) has been receipted by the applicable securities regulators, then the initial “Price to Public” specified in the Prospectus or equivalent document with respect to such Public Offering multiplied by the number of Common Shares into which each Preferred Share is then convertible.

(ii) If the net issue election is not made in connection with and contingent upon a Public Offering, then as follows:

(a) If traded on the Toronto Stock Exchange or the TSX Venture Exchange or an equivalent United States securities exchange, the fair market value of the Common Shares shall be deemed to be the volume weighted average price of the Common Shares on such exchange or market over the five trading day period ending five trading days prior to the Determination Date, and the fair market value of the Preferred Shares shall be deemed to be such fair market value of the Common Shares multiplied by the number of Common Shares into which each Preferred Share is then convertible;

(c) If there is no public market for the Common Shares, then fair market value shall be determined in good faith by the Company’s Board of Directors.

5. Partial Exercise. This Warrant may be exercised in part, and the Holder shall be entitled to receive a new warrant, which shall be dated as of the date of this Warrant, covering the number of shares in respect of which this Warrant shall not have been exercised.

If, upon exercise of this Warrant in its entirety, the Holder would, except as provided in this Section 6, be entitled to receive a fractional Preferred Share, then the number of Preferred Shares to be issued by the Company shall be rounded up or down (a fraction of 0.5 or higher being rounded up) the next higher or lower number of full Preferred Shares, as applicable, issuing a full Preferred Share with respect to such fractional share.

Notwithstanding the term of this Warrant fixed pursuant to this Section 7, and provided Holder has received advance written notice of at least five (5) business days and has not earlier exercised this Warrant, conditional upon but effective immediately prior to the consummation of a Merger (as defined below), this Warrant shall automatically be exercised pursuant to Section 4 hereof, without any action by Holder. “Merger” means: (i) a sale of all or substantially all of the Company’s assets to an Unaffiliated Entity (as defined below), or (ii) the merger, consolidation or acquisition of the Company with, into or by an Unaffiliated Entity (other than a merger or consolidation for the principal purpose of changing the domicile of the Company), that results in the transfer of fifty percent (50%) or more of the outstanding voting power of the Company (provided that, for greater certainty, no bona fide round of preferred stock equity financing shall be considered a “Merger”). “Unaffiliated Entity” means any entity that is owned or controlled by parties who own less than twenty percent (20%) of the combined voting power of the voting securities of the Company immediately prior to such merger, consolidation or acquisition. Notwithstanding the foregoing, in the event that any outstanding warrants to purchase equity securities of the Company are assumed by the successor entity of a Merger (or parent thereof), this Warrant shall also be similarly assumed. The Company agrees, subject to any applicable confidentiality restrictions, to promptly give the Holder written notice of any proposed Merger and written notice of termination of any proposed Merger. Notwithstanding anything to the contrary in this Warrant, the Holder may rescind any exercise of its purchase rights after a notice of termination of the proposed Merger if the exercise of this Warrant occurred after the Company notified the Holder that the Merger was proposed or if the exercise was otherwise precipitated by such proposed Merger, provided, however that such rescission right must be exercised within five (5) business days of receipt of such written notice of termination of the proposed Merger. In the event of such rescission, this Warrant will continue to be exercisable on the same terms and conditions.

8. Reserved Shares; Valid Issuance. The Company covenants that it will at all times from and after the date hereof reserve and keep available such number of its authorized Preferred Shares and Common Shares free from all preemptive or similar rights therein, as will be sufficient to permit, respectively, the exercise of this Warrant in full and the conversion into Common Shares of all Preferred Shares receivable upon such exercise. The Company further covenants that such shares as may be issued pursuant to such exercise and/or conversion will, upon issuance and subject to payment in full of the Purchase Price therefor, be duly and validly issued, fully paid and nonassessable and free from all Canadian taxes, liens and charges with respect to the issuance thereof.

9. (a) Share Reorganization. If at any time after the date hereof and prior to the Expiration Date the Company shall (i) subdivide or re-divide its then outstanding Preferred Shares into a greater number of Preferred Shares, (ii) reduce, combine or consolidate its then outstanding Preferred Shares into a lesser number of Preferred Shares or (iii) issue Preferred Shares (or securities exchangeable for or convertible into Preferred Shares) at no additional cost to the holders of all or substantially all of its then outstanding Preferred Shares by way of a stock dividend or other distribution, other than a dividend paid in the ordinary course or a distribution of Preferred Shares upon the exercise of any outstanding warrants or options (any of such events herein called a “Share Reorganization”), then the Purchase Price shall be adjusted effective immediately after the effective date of any such event in (i) or (ii) above or the record date at which the holders of Preferred Shares are determined for the purpose of any such dividend or distribution in (iii) above, as the case may be, by multiplying the Purchase Price in effect on such effective date or record date, as the case may be, by a fraction, the numerator of which shall be the number of Preferred Shares outstanding on such effective date or record date, as the case may be, before giving effect to such Share Reorganization and the denominator of which shall be the number of Preferred Shares outstanding immediately after giving effect to such Share Reorganization including, in the case where securities exchangeable for or convertible into Preferred Shares are distributed, the number of Preferred Shares that would be outstanding if such securities were exchanged for or converted into Preferred Shares. Upon any such adjustment to the Purchase Price, then the number of Preferred Shares purchasable pursuant to this Warrant shall be adjusted contemporaneously by multiplying the number of Preferred Shares then otherwise purchasable on the exercise thereof by a fraction, the numerator of which shall be the Purchase Price in effect immediately prior to the adjustment and the denominator of which shall be the Purchase Price resulting from such adjustment.

(b) Capital Reorganization. If at any time after the date hereof and prior to the Expiration Date there is a capital reorganization of the Company or a reclassification or other change in the Preferred Shares (other than a Share Reorganization, a Merger or a capital reorganization otherwise dealt with in Section 21) or a consolidation or merger or amalgamation of the Company with or into any other corporation or other entity (other than a consolidation, merger or amalgamation which does not result in any reclassification of the outstanding Preferred Shares or a change of the Preferred Shares into other securities), or a transfer of all or substantially all of the Company’s undertaking and assets to another corporation or other entity (other than one or more subsidiaries of the Company) in which the holders of Preferred Shares are entitled to receive shares, other securities or other property (any of such events being called a “Capital Reorganization”), after the effective date of the Capital Reorganization the Holder shall be entitled to receive, and shall accept, for the same aggregate consideration, upon exercise of the Warrants, in lieu of the number of Preferred Shares to which the Holder was theretofore entitled upon the exercise of the Wan-ants, the kind and aggregate number of shares, other securities or property resulting from the Capital Reorganization which the Holder would have been entitled to receive as a result of the Capital Reorganization if, on the effective date thereof, the Holder has been the registered holder of the number of Preferred Shares to which the Holder was theretofore entitled to purchase or receive upon the exercise of the Warrants. If determined appropriate by the Board of Directors, acting in good faith, as a result of any Capital Reorganization, appropriate adjustments shall be made in the application of the provisions of this Warrant with respect to the rights and interest thereafter of the Holder to the end that the provisions of this Warrant shall thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any shares or other securities or property thereafter deliverable upon the exercise of this Warrant.

10. Adjustments Generally. The following rules and procedures shall be applicable to the adjustments made pursuant to Section 9 herein:

(a) any Preferred Shares owned or held by or for the account of the Company shall be deemed not be to outstanding except that, for the purposes of Section 9 herein, any Preferred Shares owned by a pension plan or profit sharing plan for employees of the Company or any of its subsidiaries shall not be considered to be owned or held by or for the account of the Company;

(b) no adjustment in the Purchase Price or the number of Preferred Shares purchasable pursuant to this Warrant shall be required (i) in respect of an event described in Section 9 (other than Sections 9(a)(i) and 9(a)(ii)) if, subject to any required regulatory approvals, the Holder was entitled to participate in such event on the same terms, mutatis mutandis, as if it had exercised the Warrant prior to the effective date or record date of such event or (ii) in any event, unless a change of at least 1% of the prevailing Purchase Price or the number of Preferred Shares purchasable pursuant to this Warrant would result, provided, however, that any adjustment which, except for the provisions of this Section 10(b)(ii), would otherwise have been required to be made, shall be carried forward and taken into account in any subsequent adjustment;

(c) the adjustments provided for in Section 9 herein are cumulative and shall apply to successive subdivisions, consolidations, dividends, distributions and other events resulting in any adjustment under the provisions of such item;

(d) in the absence of a resolution of the Board of Directors of the Company fixing a record date for any dividend or distribution referred to in Section 9(iii) herein, the Company shall be deemed to have fixed as the record date therefor the date on which such dividend or distribution is effected;

(e) if the Company sets a record date to take any action and thereafter and before the taking of such action abandons its plan to take such action, then no adjustment to the Purchase Price or of the number of Preferred Shares issuable upon exercise of the Warrant will be required by reason of the setting of such record date;

(f) as a condition precedent to the taking of any action which would require any adjustment to the Warrants evidenced hereby, including the Purchase Price, the Company must take any corporate action which, in the opinion of counsel to the Company, may be necessary in order that the Company shall have unissued and reserved in its authorized capital and may validly and legally issue as fully paid and non-assessable all of the shares or other securities which the Holder is entitled to receive on the full exercise thereof in accordance with the provisions hereof;

(g) forthwith, but no later than fourteen (14) days, after any adjustment to the Purchase Price or the number of Preferred Shares purchasable pursuant to the Warrants, the Company shall provide to the Holder a certificate of the chief financial officer of the Company certifying as to the amount of such adjustment and, in reasonable detail, describing the event requiring and the manner of computing or determining such adjustment;

(h) any question or dispute that at any time or from time to time arises with respect to the amount of any adjustment to the Purchase Price or other adjustment pursuant to Section 9 herein shall be conclusively determined by a firm of independent chartered accountants (who may be the Company’s auditors) and shall be binding upon the Company and the Holder; and

(i) in case the Company, after the date of issue of this Warrant, takes any action affecting the Preferred Shares, other than an action described in Section 9 herein, which in the opinion of the Board of Directors of the Company would materially affect the rights of the Holder, the Purchase Price will be adjusted in such manner, if any, and at such time, by action by the Board of Directors of the Company but subject in all cases to any necessary regulatory approval (including any stock exchange or quotation system on which the Preferred Shares are then listed and posted (or quoted) for trading, as applicable). Failure of the taking of action by the Board of Directors of the Company so as to provide for an adjustment on or prior to the effective date of any action by the

Company affecting the Preferred Shares will be conclusive evidence that the Board of Directors of the Company has determined that it is equitable to make no adjustment in the circumstances. For greater certainty, neither the creation of a new series of Class B preferred shares of the Company, nor the creation of a new class of preferred shares that ranks ahead of the Class B preferred shares of the Company and whose creation is approved by the shareholders of the Company in accordance with the terms of the Articles and the Shareholders Agreement of the Company, shall be deemed to materially adversely affect the rights of the Holder hereunder.

11. Adjustments for Diluting Issuances. The other antidilution rights applicable to the Preferred Shares of the Company are set forth in the Company’s Articles of Amendment, as amended from time to time (the “Articles”), a true and complete copy in its current form which is attached hereto as Exhibit A. Such rights shall not be restated, amended or modified in any manner which affects the Holder differently than the holders of Preferred Shares without such Holder’s prior written consent. The Company shall promptly provide the Holder hereof with any proposed restatement, amendment or modification to the rights attaching to the Preferred Shares, as set forth in the Articles, and in any event no later than five (5) business days prior to such proposed restatement, amendment or modification being made.

12. Notices of Record Date, Etc. In the event of:

(a) any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or any right to subscribe for, purchase, sell or otherwise acquire or dispose of any shares of stock of any class or any other securities or property, or to receive any other right;

(b) any reclassification of the capital of the Company, capital reorganization of the Company, consolidation or merger involving the Company, or sale or conveyance of all or substantially all of its assets; or

(c) any voluntary or involuntary dissolution, liquidation or winding-up of the Company;

then in each such event the Company will provide or cause to be provided to the Holder a written notice thereof. Such notice shall be provided at least five (5) business days prior to the date specified in such notice on which any such action is to be taken.

13. Representations, Warranties and Covenants. This Warrant is issued and delivered by the Company and accepted by each Holder on the basis of the following representations, warranties and covenants made by the Company:

(a) The Company has all necessary authority to issue, execute and deliver this Warrant and to perform its obligations hereunder.

Attached hereto as Exhibit B is a capitalization table summarizing the capitalization of the Company as of the date hereof. At the request of Holder, not more than once per calendar quarter, the Company will provide Holder with a current capitalization table indicating changes, if any, to the number of outstanding Common Shares and Preferred Shares.

(g) The Company covenants and agrees that while any of the Warrants shall be outstanding, the Company shall (a) comply with the securities legislation applicable to it in order that the Company not be in default of any requirements of such legislation; and (b) use its commercially reasonable best efforts to do or cause to be done all things necessary to preserve and maintain its corporate existence. All Preferred Shares which shall be issued upon the exercise of the right to purchase herein provided for, subject to payment therefor of the amount at which such Preferred Shares may at the time be purchased pursuant to the provisions hereof, shall be issued as fully paid and non-assessable shares of the Company.

14. Registration Rights. Concurrently herewith, the Company is granting to the Holder, effective upon exercise of the Warrants, all the rights of an “Investor” under the Company’s Amended and Restated Registration Rights Agreement dated as of January 27, 2010, as amended.

15. Amendment. The terms of this Warrant may be amended, modified or waived only with the written consent of the Holder and the Company, subject in all cases to any necessary regulatory approval (including any stock exchange or quotation system on which the Preferred Shares are then listed and posted (or quoted) for trading, as applicable).

16. Representations and Covenants of the Holder. This Warrant has been entered into by the Company in reliance upon the following representations and covenants of the Holder, which by its execution hereof the Holder hereby confirms:

(a) Investment Purpose. The right to acquire Preferred Shares or the Preferred Shares issuable upon exercise of the Holder’s rights contained herein will be acquired for investment and not with a view to the sale or distribution of any part thereof, and the Holder has no present intention of selling or engaging in any public distribution of the same except pursuant to a registration or exemption.

(b) Accredited Investor. Holder is an “accredited investor” within the meaning of the Securities and Exchange Rule 501 of Regulation D, and Regulation 45-106 (Prospectus and Registration Exemptions), in each case as presently in effect.

(c) Private Issue. The Holder understands (i) that the Preferred Shares issuable upon exercise of the Holder’s rights contained herein are not registered under the 1933 Act or qualified under applicable state securities laws on the ground that the issuance contemplated by this Warrant will be exempt from the registration and qualifications requirements thereof, and (ii) that the Company’s reliance on such exemption is predicated on the representations set forth in this Section 16.

(d) Financial Risk. The Holder has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its investment and has the ability to bear the economic risks of its investment.

(e) No Listing. The Holder acknowledges the fact that neither the Preferred Shares nor any other securities of the Company are listed on any stock exchange or quoted on any securities quotation service, that they may never become listed or quoted thereon, that a market therefore may never develop, that the Company is not a “reporting issuer” (or the equivalent thereof) in any jurisdiction, that the Preferred Shares are subject to an indefinite “hold period” under applicable Canadian and United States securities legislation and that it will not be able to resell the Preferred Shares until the expiration of the applicable “hold period” (which period, in most Canadian jurisdictions, will not commence until after the Company has become a “reporting issuer”) except in accordance with limited exemptions under applicable securities legislation and regulatory policy and in compliance with the other requirements of applicable laws.

(f) Legend. The Holder it acknowledges that the certificates representing the Preferred Shares will bear, as of the date of issue, the following legend in substantially the following form:

“UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE THE DATE THAT IS 4 MONTHS AND A DAY AFTER THE LATER OF [INSERT CLOSING DATE[ AND THE DATE THE COMPANY BECAME A REPORTING ISSUER IN ANY PROVINCE OR TERRITORY.”

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “1933 ACT”) OR STATE SECURITIES LAWS. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF ENERKEM INC. THAT SUCH SECURITIES MAY BE OFFERED, SOLD OR OTHERWISE TRANSFERRED ONLY (A) TO ENERKEM INC., (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE 1933 ACT AND IN COMPLIANCE WITH APPLICABLE LOCAL LAW AND REGULATIONS, (C) IN THE UNITED

STATES IN ACCORDANCE WITH RULE 144 UNDER THE 1933 ACT OR (D) PURSUANT TO ANOTHER EXEMPTION FROM REGISTRATION UNDER THE 1933 ACT, AND IN EACH CASE, IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAWS AFTER, IN THE CASE OF TRANSFERS UNDER CLAUSE (D), THE HOLDER HAS FURNISHED TO ENERKEM INC. AN OPINION OF COUNSEL OF RECOGNIZED STANDING OR OTHER EVIDENCE REASONABLY SATISFACTORY TO ENERKEM INC.. THAT SUCH TRANSFER IS EXEMPT FROM REGISTRATION UNDER THE 1933 ACT AND APPLICABLE SECURITIES LAWS.

DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA.”

(g) Lock-up. If requested by the lead underwriter or agent of a Public Offering, the Holder shall enter into an agreement in form and substance satisfactory to such lead underwriter and the Company, acting reasonably, substantially to the effect that such Holder shall not be entitled, directly or indirectly, to sell, transfer or otherwise dispose of, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic value as a sale of, any shares, warrants or convertible securities of the Company for such period of time (not to exceed 180 days) as the lead underwriter may require following completion of such Public Offering or secondary public offering of securities of the Company, plus a period of up to 34 days thereafter to comply with applicable FINRA rules.

17. Notices, Transfers, Etc.

(a) Any notice or written communication required or permitted to be given to the Holder may be given by certified mail or delivered to the Holder at the address most recently provided by the Holder to the Company.

(b) This Warrant may not be transferred or assigned, in whole or in part, without the prior written consent of the Company, which consent may not be unreasonably withheld. Notwithstanding the foregoing, and subject to compliance with applicable federal, provincial and state securities laws and upon reasonable prior notice by the Holder to the Company, this Warrant may be transferred by the Holder with respect to all but not less than all of the shares purchasable hereunder (i) to any affiliate of Holder, or (ii) to any acquirer of all or any significant portion of Holder’s assets or the indebtedness of the Company owing to the Holder pursuant to the Loan Agreement. In no circumstance may the Warrant be transferred to a competitor of the Company without the Company’s prior written consent. In the case of any permitted transfer, upon surrender of this Warrant to the Company, together with the assignment notice annexed hereto duly executed, the Company shall issue a new warrant of the same denomination to the transferee and, upon such reissuance, the warrant will not be further transferable or assignable by the transferee without the prior written consent of the Company.

(c) Nothing herein contained shall be construed as conferring upon the Holder any right or interest as a holder of shares of the Company or any other right or interest except as specifically herein provided. Upon exercise of the Warrant, in whole or in part, the Holder hereby agrees to execute an agreement to be bound by the terms of any Shareholder Agreement in effect at such time among the Company and its shareholders.

(d) In case this Warrant shall be mutilated, lost, stolen or destroyed, the Company shall issue a new warrant of like tenor and denomination and deliver the same (i) in exchange and substitution for and upon surrender and cancellation of any mutilated Warrant, or (ii) in lieu of any Warrant lost, stolen or destroyed, upon receipt of an affidavit of the Holder or other evidence reasonably satisfactory to the Company of the loss, theft or destruction of such Warrant, together with such indemnity as may be reasonably required by the Company in connection therewith.

18. Governing Law. The provisions and terms of this Warrant shall be governed by and construed in accordance with the internal laws of the Province of Quebec and federal laws applicable therein without giving effect to its principles regarding conflicts of laws.

19. Successors and Assigns. This Warrant shall be binding upon the Company’s successors and assigns and shall inure to the benefit of the Holder’s successors, legal representatives and permitted assigns.

20. Business Days. If the last or appointed day for the taking of any action required or the expiration of any rights granted herein shall be a Saturday or Sunday or a legal holiday in Montreal, Quebec or Xxxxxxx, Xxxxxxx, then such action may be taken or right may be exercised on the next succeeding business day which is not a Saturday or Sunday or such a legal holiday.

21. Qualifying Public Offering. If the Company shall effect a firm commitment underwritten Public Offering of Common Shares which results in the conversion of the Preferred Shares into Common Shares pursuant to the Company’s Articles in effect immediately prior to such offering, then, effective upon such conversion, this Warrant shall change from the right to purchase Preferred Shares to the right to purchase Common Shares, and the Holder shall thereupon have the right to purchase, at a total price equal to that payable upon the exercise of this Warrant in full, the number of Common Shares which would have been receivable by the Holder upon the conversion into Common Shares of all Preferred Shares then issuable upon exercise of this Warrant, and in such event appropriate provisions shall be made with respect to the rights and interest of the Holder to the end that the provisions hereof (including, without limitation, the provisions for the adjustment of the Purchase Price and of the number of shares purchasable upon exercise of this Warrant and the provisions relating to the net issue election) shall thereafter be applicable to any Common Shares deliverable upon the exercise hereof.

Any reference to “the Collateral” in this Agreement shall be interpreted as referring to “the Collateral or any of it.”

(b) “Equity Interests” means shares, units, trust units, partnership, membership or other interests, participations or other equivalent rights in an Issuer’s equity or capital, however designated and whether voting or non-voting, warrants, options or other rights to acquire any of the foregoing and securities convertible into or exchangeable for any of the foregoing.

1.2 PPSA Definitions In this Agreement, except where the context otherwise requires, the words “account,” “certificated security,” “control,” “instrument,” “investment property,” “money,” “option,” “proceeds,” “securities account,” “securities intermediary,” “security,” “security certificate” and “uncertificated security” shall have the same meanings as their defined meanings where they are defined in the PPSA.

1.3 Paramountcy If there is any conflict or inconsistency between the terms of the Loan Agreement and the terms of this Agreement, the provisions of the Loan Agreement shall govern to the extent necessary to remove the conflict or inconsistency.

1.4 Other Interpretation Rules In this Agreement:

(a) The division into Sections and the insertion of headings are for convenience of reference only and do not affect the construction or interpretation of this Agreement.

(b) Unless otherwise specified or the context otherwise requires, (i) “including” or “includes” means “including (or includes) but is not limited to” and shall not be construed to limit any general statement preceding it to the specific or similar items or matters immediately following it, (ii) a reference to any legislation, statutory instrument or regulation or a section of it is a reference to the legislation, statutory instrument, regulation or section as amended, restated and re-enacted from time to time, and (iii) words in the singular include the plural and vice-versa and words in one gender include all genders.

2. GRANT OF SECURITY, ETC.

2.1 Grant of Security As security for payment and performance of the Obligations, the Obligor mortgages, charges, assigns, transfers and pledges the Collateral to the Lender as a fixed and specific mortgage and charge, and grants the Lender a security interest in the Collateral.

2.2 Attachment The Obligor agrees that the Lender has given value and that the liens created by this Agreement are intended to attach (a) with respect to Collateral that is now in existence, upon execution of this Agreement, and (b) with respect to Collateral that

comes into existence in the future, upon the Obligor acquiring rights in the Collateral or the power to transfer rights in the Collateral to the Lender. In each case, the parties do not intend to postpone the attachment of any lien created by this Agreement.

2.3 Continuing Agreement The liens created by this Agreement are continuing, to secure a current or running account, and will extend to the ultimate balance of the Obligations, regardless of any intermediate payment or discharge of the Obligations in whole or in part.

2.4 In Addition to Other Rights; No Marshalling This Agreement is in addition to and is not in any way prejudiced by or merged with any other lien now or subsequently held by the Lender in respect of any Obligations. The Lender shall be under no obligation to marshal in favour of the Obligor any other lien or any money or other property that the Lender may be entitled to receive or may have a claim upon.

2.5 Liabilities Unconditional The liabilities of the Obligor under this Agreement are absolute and unconditional, and will not be affected by any act, omission, matter or thing that, but for this Section, would reduce, release or prejudice any of its liabilities under this Agreement, whether or not known to it or the Lender or consented to by it or the Lender.

2.6 Merger of Obligor If the Obligor amalgamates or merges with one or more other entities, the Obligations and the liens created by this Agreement shall continue as to the Obligations and the Collateral of the Obligor at the time of amalgamation or merger, and shall extend to the Obligations and the Collateral of the amalgamated or merged entity, and the term Obligor shall extend to the amalgamated or merged entity, all as if the amalgamated or merged entity had executed this Agreement as the Obligor.

2.7 Limitation Periods To the extent that any statutory limitation period applies to any claim for payment of the Obligations or remedy for enforcement of the Obligations, the Obligor agrees that:

(a) any limitation period is expressly excluded and waived entirely if permitted by applicable law;

(b) if a complete exclusion and waiver of any limitation period is not permitted by applicable law, any limitation period is extended to the maximum length permitted by applicable law;

(c) any applicable limitation period shall not begin before an express demand for payment of the Obligations is made in writing by the Lender to the Obligor;

(d) any applicable limitation period shall begin afresh upon any payment or other acknowledgment of the Obligations by the Obligor; and

(e) this Agreement is a “business agreement” as defined in the Limitations Act, 2002 (Ontario) if that Act applies.

3. REPRESENTATIONS OF OBLIGOR

3.1 Representations The Obligor represents and warrants to the Lender as follows, as at the date hereof, acknowledging that its representations and warranties are material, will be relied upon by the Lender (notwithstanding any investigation made by the Lender at any time) and shall survive the execution and delivery of this Agreement without any time limitation:

(a) The Obligor is the registered and beneficial owner of all of the Equity Interests described on Schedule A, which have been validly issued and are outstanding as fully paid and non-assessable.

(b) Schedule A contains a true and complete list of all of the Equity Interests of each Issuer owned by the Obligor.

(c) The Equity Interests described on Schedule A represent 100% of the issued and outstanding Equity Interests of all classes of the Issuers (other than with respect to Enerkem Alberta Biofuels G.P. Inc. and 7037163 Canada Inc.) and represent 50% of the issued and outstanding Equity Interests of all classes of Enerkem Alberta Biofuels G.P. Inc. and 7037163 Canada Inc.

(d) All of the Obligor’s right, title and interest in, to and under the Collateral may be freely assigned and transferred to the Lender, and the liens created in the Collateral may be dealt with by the Lender as provided in this Agreement without obtaining any approval or consent of any person or the filing of any document or the fulfilment of any legal requirement or the taking of any proceeding, other than any approval or consent that may be required from the board of directors or shareholders of an Issuer pursuant to its constating documents which has already been obtained and will be maintained in full force and effect during the term of this Agreement, and other approvals and consents as described on Schedule B, provided that if the Lender or a transferee of the Lender becomes the owner of the Equity Interests in 7037163 Canada Inc. pledged hereunder by way of a realization hereunder, such owner will be required to comply with the provisions of the shareholders’ agreement in respect of 7037163 Canada Inc. described in Schedule B.

(e) There is no existing agreement, option, right or privilege capable of becoming an agreement or option pursuant to which the Obligor would be required to sell or otherwise dispose of any of the Collateral.

(f) The Lender is not acting as agent of the Obligor in any way with respect to the Collateral.

(g) No part of the Collateral now consisting of uncertificated securities has ever been evidenced or represented by certificated securities and those uncertificated securities are not evidenced or represented by any other document evidencing ownership of them.

(h) No person, other than the Lender, now has control (for purposes of the PPSA) of any part of the Collateral.

(i) The Obligor does not have any liability under applicable law or under the certificate and/or articles of incorporation, association, amalgamation or continuance, partnership agreement or other similar constating document, by laws or shareholder agreements in respect of any Issuer, as holder of the Equity Interests forming part of the Collateral, for any debts, liabilities or obligations of the Issuer of the Equity Interest.

(j) Every Equity Interest forming part of the Collateral that is an interest in a partnership or limited liability company is a security.

4. RIGHTS AND OBLIGATIONS OF THE OBLIGOR

4.1 Restrictions on Liens and Dispositions The Obligor shall not create, assume, incur or permit the existence of any lien on the Collateral except as permitted in the Loan Agreement, nor shall the Obligor sell, lend or otherwise dispose of the Collateral, or permit such a disposition to occur, except as expressly permitted in the Loan Agreement.

4.2 Possession and Control of Collateral The Obligor shall take whatever steps the Lender requires from time to time to enable the Lender to obtain control of any investment property forming part of the Collateral, including (a) arranging for any securities intermediary or issuer of uncertificated securities to enter into an agreement satisfactory to the Lender to enable the Lender to obtain control, (b) delivering any certificated security to the Lender with any necessary endorsement and (c) upon the occurrence of an Event of Default that is continuing, having any Equity Interest registered in the name of the Lender or its nominee.

4.3 Safekeeping The Lender is not obligated to keep any Collateral separate or identifiable or to take steps to preserve rights relating to Collateral against prior parties or other persons. The Lender shall have no duty with respect to any Collateral delivered to it other than to use the same degree of care in the safe custody of the Collateral delivered to it that it uses with respect to similar property that it owns of similar value. Without limiting the foregoing, the Lender may lodge Collateral with any bank or trust company, to be held in safekeeping on behalf of the Lender (without incurring any liability for any act or omission of the bank or trust company), or may hold Collateral itself. The Obligor shall reimburse the Lender on demand for all reasonable expenses incurred by the Lender in connection with safekeeping with interest from the date the expenses are incurred until paid at the highest rate of interest applicable to the Obligations. The expenses and interest shall form part of the Obligations.

4.4 Receipts by Obligor If the Obligor receives any certificate representing Equity Interests of any Issuer (including any certificate representing a dividend or distribution in connection with any reclassification, increase or reduction of capital or any certificate issued in connection with any reorganization), whether in addition to, in substitution for, as a conversion of, or in exchange for any portion of the Collateral, or otherwise, the

Obligor shall hold the certificate in trust for the Lender and immediately deliver it to the Lender in the form received with any endorsement required by the Lender, to be held by the Lender as part of the Collateral. In addition, if the Obligor receives any money or other property as a distribution upon the partial or complete liquidation or dissolution of any Issuer, the Obligor shall hold the money or property in trust for the Lender and immediately deliver it to the Lender in the form received to be held by the Lender as part of the Collateral.

4.5 Other Assurances; Power of Attorney On request by the Lender, the Obligor shall execute, acknowledge and deliver all financing statements, certificates, further assignments, documents, transfers, stock transfer powers, proxies, instruments, security documents, acknowledgments and assurances and do all further acts and things as the Lender may consider necessary or desirable to give effect to the intent of this Agreement, or for the collection, disposition, realization or enforcement of the Collateral or the liens created by this Agreement. The Obligor constitutes and appoints the Lender its true and lawful attorney, with full power of substitution, to do any of the foregoing or any other things that the Obligor has agreed to do in this Agreement, whenever and wherever the Lender may consider it to be necessary or desirable, upon the occurrence of an Event of Default that is continuing and to use the Obligor’s name in the exercise of the Lender’s rights under this Agreement. This power of attorney is coupled with an interest and is irrevocable by the Obligor.

4.6 Proceeds Before Default Subject to Section 4.4 above and to the provisions of the Loan Agreement, until the occurrence of an Event of Default, the Obligor may receive any payments or other proceeds relating to the Collateral.

4.7 Voting Before Default Until the occurrence of an Event of Default which is continuing, the Obligor may exercise, either directly or, if any Equity Interest is registered in the name of the Lender or its nominee, pursuant to proxies or powers of attorney (which shall be given at the expense of the Obligor), all of the rights and powers of a holder of the Equity Interests forming part of the Collateral, including the right to vote. However, the Obligor shall not exercise those rights and powers in a way that would (a) violate or be inconsistent with the Loan Agreement, (b) by reason of any recapitalization, reclassification or similar action or by reason of any amendment to the constating documents of any Issuer, reduce the value of the Collateral as security for the Secured Obligations or impose any new restriction on the transferability of any of the Collateral, or (c) otherwise prejudice the interests of the Lender.

4.8 Lender May Perform Obligor’s Duties If the Obligor fails to perform any of its duties under this Agreement, the Lender may, but shall not be obligated to, perform any or all of those duties, without waiving any rights to enforce this Agreement. The Obligor shall pay the Lender, immediately on written demand, an amount equal to the costs, fees and expenses incurred by the Lender in doing so plus interest from the date the costs, fees and expenses are incurred until paid at the highest rate of interest applicable to the Obligations. The costs, fees, expenses and interest shall be included in the Obligations under this Agreement.

4.9 Lender Not Liable for Obligor’s Agreements Nothing in this Agreement shall make the Lender liable to observe or perform any term of any agreement to which the Obligor is a party or by which it or the Collateral is bound, or make the Lender a mortgagee in possession. The Obligor shall indemnify the Lender and save it harmless from any claim arising from any such agreement.

4.10 Release of Liens If the Obligor has indefeasibly paid the Obligations in full in cash and otherwise performed all of the terms of the Loan Documents, and if all obligations of the Lender to extend credit under any Loan Document have been cancelled, then the Lender shall, at the request and expense of the Obligor, release the liens created by this Agreement, return to the Obligor any certificated security forming part of the Collateral that has been delivered to the Lender, and execute and deliver whatever documents are reasonably required to do so.

4.11 Acknowledgement Notwithstanding anything contained herein to the contrary, the Lender acknowledges that, in order to become the owner of any Equity Interests of any Issuer in which the Obligor has an investment which consists of less than 100% of the issued and outstanding Equity Interests of such Issuer, there may be requirements under the shareholders/securityholders agreement or partnership agreement, as the case may be, which affect such Equity Interests that form part of the Collateral, which need to be respected.

5. RIGHTS AND OBLIGATIONS ON DEFAULT

5.1 Application of Article The provisions of this article 5 apply on the occurrence of an Event of Default that is continuing.

5.2 Termination of Further Credit and Acceleration of Obligations The Lender shall be under no obligation to make further advances or otherwise extend further credit and the Lender may declare that the Obligations are immediately due and payable in full, but upon the occurrence of an Event of Default contemplated in Section 8.10 or 8.11 of the Loan Agreement which is continuing, then without prejudice to the other rights of the Lender as a result of any of those events, without notice or action of any kind by the Lender and without presentment, demand or protest of any nature or kind, the Lender’s obligation to make advances or otherwise extend credit shall immediately terminate and the Obligations shall become immediately due and payable. Upon the Obligations becoming due and payable, the Lender may enforce payment of the Obligations and the Lender shall have the rights and remedies of a secured party under the PPSA and other applicable law together with those rights and remedies provided by this Agreement or otherwise provided by applicable law.

5.3 Proceeds After Default The Lender may hold and/or use the Collateral in the manner and to the extent that the Lender may consider appropriate. The Lender may take charge of all proceeds of the Collateral and may hold them as additional security for the Obligations. The Lender may give notice to any Issuer to direct all payments or other proceeds relating to the Collateral to the Lender and any payments or other proceeds of the Collateral received by the Obligor from Issuers or from any persons liable to the

Obligor in connection with the Collateral, after notice is given by the Lender, shall be held by the Obligor in trust for the Lender and immediately paid over to the Lender. The Lender shall not, however, be required to collect any proceeds of the Collateral. The Lender may also enforce any rights of the Obligor in respect of the Collateral by any manner permitted by law.

5.4 Voting After Default The Lender may have any Collateral registered in its name or in the name of its nominee and shall be entitled but not required to exercise voting and other rights that the holder of that Collateral may at any time have, but the Lender shall not be responsible for any loss occasioned by the exercise of those rights or by failure to exercise them. The Lender may also enforce its rights under any agreement with any securities intermediary or issuer of uncertificated securities.

5.5 Notice of Disposition If required to do so by applicable law, the Lender shall give the Obligor written notice of any intended disposition of the Collateral in accordance with the Loan Agreement or by any other method required or permitted by applicable law. The Obligor waives giving of notice to the maximum extent permitted by applicable law.

5.6 Statutory Waivers To the maximum extent permitted by law, the Obligor waives all of the rights, benefits and protections given by any present or future statute that imposes limits on the rights, remedies or powers of the Lender or on the methods of realization of security, including any seize or xxx or anti-deficiency statute or any similar provisions of any other statute.

5.7 Disposition and Other Rights of Lender The Lender may (a) make payments on account of, to discharge, or to obtain an assignment of any lien on the Collateral, whether or not ranking in priority to the liens created by this Agreement, (b) borrow money required for the seizure, retaking, repossession, holding, insuring, maintaining, protecting, preserving, preparing for disposition or disposition of the Collateral or for any other enforcement of this Agreement on the security of the Collateral in priority to the liens created by this Agreement, (c) file proofs of claim and other documents to establish the claims of the Lender in any proceeding relating to the Obligor, (d) sell or otherwise dispose of all or any part of the Collateral at public auction, by public tender or by private sale or other disposition, either for cash or on credit, at such time and on such terms and conditions as the Lender may determine, and (e) complete blanks in any endorsement by the Obligor of a certificated security in order to complete a disposition. If any disposition involves deferred payment, the Lender will not be accountable for and the Obligor will not be entitled to be credited with the proceeds of disposition until payment is actually received in cash. On any disposition, the Lender shall have the right to acquire all or any part of the Collateral that is offered for disposition and the rights of the Obligor in that Collateral shall be extinguished. The Lender may also accept the Collateral in satisfaction of the Obligations or may from time to time designate any part of the Obligations to be satisfied by the acceptance of particular Collateral that the Lender reasonably determines to have a net realizable value equal to the amount of the designated part of the Obligations, in which case only the designated part of the Obligations shall be satisfied by the acceptance of the particular Collateral.

5.8 Commercially Reasonable Actions and Omissions The Obligor agrees that it is commercially reasonable for the Lender (a) not to incur expenses that it reasonably considers significant to prepare Collateral for disposition, (b) to obtain or, if not required by other law, not to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (c) not to exercise collection remedies against Issuers or other persons liable to the Obligor in connection with the Collateral or to remove liens on or adverse claims against Collateral, (d) to exercise collection remedies against Issuers and other persons liable in connection with the Collateral directly or through the use of collection agencies and other collection specialists, (e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (f) to contact other persons, whether or not in the same business as the Obligor, for expressions of interest in acquiring all or any portion of the Collateral, (g) to hire one or more professional auctioneers or other persons, including employees of the Obligor, brokers, investment bankers, consultants and other professionals to assist in the collection or disposition of Collateral, whether or not the Collateral is of a specialized nature, (h) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets, (i) to disclaim disposition warranties, (j) to vary or rescind any contract for the disposition of any Collateral, or (k) to purchase insurance or credit enhancements or take other steps to insure the Lender against risks of loss, collection or disposition of Collateral or to provide the Lender a guaranteed return from the collection or disposition of Collateral. The Lender is not required to take steps to qualify, or cause to be qualified, any securities forming part of the Collateral for public distribution or request the Issuer to qualify them. The Lender need not dispose of any securities by public distribution even if they are qualified for public distribution. The Lender may dispose of securities by an exemption from the prospectus requirements of applicable securities legislation as it considers appropriate notwithstanding that doing so may require them to comply with limitations or restrictions relating to the exemption. The limitations or restrictions may include complying with procedures that may restrict the number of prospective bidders and purchasers, requiring that prospective bidders and purchasers have certain qualifications (including being accredited investors, agreeing to pay a minimum price or demonstrating qualifications required to obtain any approval of the sale or resulting purchase that is required under applicable law), and restricting prospective bidders and purchasers to those who will represent and agree that they are purchasing as principal for their own account for investment and not with a view to distribution or resale. The Obligor acknowledges that the purpose of this Section is to provide selected examples of actions and omissions that would be commercially reasonable in the Lender’s exercise of remedies against the Collateral and that other actions and omissions shall not be considered commercially unreasonable solely on account of not being mentioned in this Section, nor shall the Lender be liable or accountable for any discount attributable to the specified actions and omissions. Nothing in this Section shall be construed to grant any rights to the Obligor or to impose any duties on the Lender that would not have been granted or imposed by this Agreement or by applicable law in the absence of this Section. In exercising its rights and obligations under this Agreement, the Lender shall not be responsible or liable to the Obligor or any

other person for any loss or damage from the realization or disposal of any Collateral or the enforcement of this Agreement, or any failure to do so, or for any act or omission on their respective parts or on the part of any of their directors, officers, employees, agents or advisors in that connection, except that the Lender may be responsible or liable for loss or damage arising from its wilful misconduct or gross negligence.

5.9 Costs of Realization All costs incurred in connection with realizing the security constituted by this Agreement or exercising any of the Lender’s rights under this Agreement, including costs incurred in connection with repossessing, holding, insuring, repairing, processing, preparing for disposition, and disposing of any Collateral and legal fees on a full indemnity (sometimes called solicitor and own client) basis (in this Section, “realization costs”) shall be payable by the Obligor to the Lender immediately on demand. Realization costs shall bear interest from the date they are incurred until paid at the highest rate of interest applicable to the Obligations. Realization costs and interest shall be included in the Obligations under this Agreement.

5.10 Other Security; Application of Money The Lender may (a) refrain from enforcing any other security or rights held by or on behalf of the Lender in respect of the Obligations, or enforce any other security or rights in any manner and order as it sees fit, and (b) apply any money received from or in respect of the Collateral in any manner and order as it sees fit and change any application of money received in whole or in part from time to time, or refrain from applying any money and hold it in a suspense account.

5.11 Third Parties No person dealing with the Lender is required to determine (a) whether the liens created by this Agreement or the powers purporting to be exercised have become enforceable, (b) whether any Obligations remain owing, (c) the propriety of any aspect of the disposition of Collateral or (d) how any payment to the Lender has been or will be applied. Any person who acquires Collateral from the Lender in good faith shall acquire it free from any interest of the Obligor.

5.12 Rights Cumulative No failure on the part of the Lender to exercise, nor any delay in exercising, any right or remedy under any Loan Document or this Agreement shall operate as a waiver or impose any liability on the Lender, nor shall any single or partial exercise of any right or remedy prevent any further or other exercise or the exercise of any other right or remedy. The rights and remedies provided in this Agreement are cumulative and do not exclude any rights and remedies provided by applicable law. If the Lender has enforced any right or remedy under this Agreement and the enforcement proceeding has been discontinued, abandoned or determined adversely to the Lender for any reason, then the Obligor and the Lender shall, without any further action, be restored to their previous positions to the maximum extent permitted by law and subject to any determination in the enforcement proceeding or express agreement between the Obligor and the Lender, and thereafter all rights and remedies of the Lender shall continue as if no enforcement proceeding had been taken.

5.13 Obligor Liable for Deficiency If the proceeds arising from the disposition of the Collateral fail to satisfy the Obligations, the Obligor shall pay any deficiency to the Lender on demand. Neither the taking of any judicial or extra-judicial proceeding nor the

exercise of any power of seizure or disposition or other remedy shall extinguish the liability of the Obligor to pay and perform the Obligations, nor shall the acceptance of any payment or alternate security create any novation. No covenant, representation or warranty of the Obligor in this Agreement shall merge in any judgment.

5.14 Release by Obligor The Obligor hereby releases and discharges the Lender from all claims of any kind, whether sounding in damages or not, that may arise or be caused to the Obligor or any person claiming through or under the Obligor as a result of any act or omission of the Lender or any receiver except that the Lender may be responsible or liable for loss or damage arising from its wilful misconduct or gross negligence.

6. NOTICES

6.1 Notices in Writing Any communication to be made under this Agreement shall be made in accordance with the Loan Agreement.

7. ENTIRE AGREEMENT; SEVERABILITY

7.1 Entire Agreement This Agreement embodies all the agreements between the Obligor and the Lender relating to the liens created in this Agreement and the related rights and remedies. No party shall be bound by any representation or promise made by any person relating to this Agreement that is not embodied in it. Any waiver of, or consent to departure from, the requirements of any provision of this Agreement shall be effective only if it is in writing and signed by the Lender, and only in the specific instance and for the specific purpose for which it has been given.

7.2 Severability If, in any jurisdiction, any provision of this Agreement or its application to any circumstance is restricted, prohibited or unenforceable, that provision shall, as to that jurisdiction, be ineffective only to the extent of that restriction, prohibition or unenforceability without invalidating the remaining provisions of this Agreement, without affecting the validity or enforceability of that provision in any other jurisdiction and, if applicable, without affecting its application to other circumstances.

8. DELIVERY OF AGREEMENT

8.1 Counterparts This Agreement may be executed in any number of counterparts and all counterparts taken together shall be deemed to constitute one agreement.

8.2 Delivery To evidence the fact that it has executed this Agreement, the Obligor may send a signed copy of this Agreement or its signature to this Agreement by facsimile transmission or e-mail and the signature sent in that way shall be deemed to be its original signature for all purposes.

8.3 No Conditions Possession of this Agreement by the Lender shall be conclusive evidence against the Obligor that the Agreement was not delivered in escrow or pursuant to any agreement that it should not be effective until any condition precedent or subsequent has been complied with. This Agreement shall be operative and binding notwithstanding that it is not executed by any proposed signatory.

8.4 Receipt and Waiver The Obligor acknowledges receipt of a copy of this Agreement. The Obligor waives any notice of acceptance of this Agreement by the Lender. The Obligor also waives the right to receive a copy of any financing statement or financing change statement that may be registered in connection with this Agreement or any verification statement issued with respect to a registration, if waiver is not otherwise prohibited by law. The Obligor agrees that the Lender may from time to time provide information regarding this Agreement, the Collateral and the Obligations to persons that the Lender believes in good faith are entitled to the information under applicable law.

9. GOVERNING LAW

9.1 Governing Law This Agreement and any dispute arising from or in relation to this Agreement shall be governed by, and interpreted and enforced in accordance with, the law of the Province of Ontario and the laws of Canada applicable in that province, excluding the conflict of law rules of that province.

9.2 Obligor’s Exclusive Dispute Resolution Jurisdiction The Obligor agrees that the courts of the Province of Ontario have exclusive jurisdiction over any dispute arising from or in relation to this Agreement and the Obligor irrevocably and unconditionally attorns to the exclusive jurisdiction of that province. The Obligor agrees that the courts of that province are the most appropriate and convenient forum to settle disputes and agrees not to argue to the contrary.

9.3 Lender Entitled to Concurrent Jurisdiction Despite Section 9.2, the Lender is permitted to take proceedings in relation to any dispute arising from or in relation to this Agreement in any court of another province or another state with jurisdiction and to the extent allowed by law may take concurrent proceedings in any number of jurisdictions.

10. SUCCESSORS AND ASSIGNS

10.1 Successors and Assigns The Obligor may not assign or transfer all or any part of its liabilities under this Agreement. All rights of the Lender under this Agreement shall be assignable in accordance with the Loan Agreement and the Obligor shall not assert against any assignee any claim or defence that the Obligor now has or may in the future have against the Lender in connection with any arrangement, document or agreement (other than under or in connection with a Loan Document) and any transactions pursuant to any such arrangement, document or agreement. This Agreement shall enure to the benefit of the Lender and its successors and assigns and be binding on the Obligor and its successors and any permitted assigns.

1.2 Other Interpretation Rules In this Agreement:

2. GUARANTEE AND INDEMNITY

2.1 Guarantee The Obligor unconditionally guarantees payment to the Lender of the Obligations.

2.2 Indemnity The Obligor also unconditionally agrees that, if the Borrower does not unconditionally and irrevocably pay any Obligations when due and those Obligations are not recoverable from the Obligor for any reason under Section 2.1, the Obligor shall indemnify the Lender immediately on demand against any cost, loss, damage, expense or liability suffered by the Lender as a result of the Borrower’s failure to do so.

2.3 Separate Liabilities The liabilities of the Obligor under Sections 2.1 and 2.2 are separate and distinct from each other, but the provisions of this Agreement shall apply to the liabilities under both of those Sections unless the context otherwise requires.

Each of the defences mentioned above is waived by the Obligor to the fullest extent permitted under applicable law.

4.3 Information Concerning Borrower The Obligor acknowledges that it is presently familiar with the Loan Documents, the financial condition of the Borrower and any other circumstances affecting the risk incurred by the Obligor in connection with this Agreement. The Obligor shall be solely responsible for keeping itself informed concerning those matters in the future. The Obligor acknowledges that the Lender has no obligation to provide any information concerning those matters now or in the future and that, if it does so at any time, it shall have no obligation to update the information or provide other information subsequently.

4.4 No Obligation to Enforce Other Rights The Obligor waives any right it may have of requiring the Lender (or any trustee or agent on its behalf) to proceed against or enforce any other rights or security or claim payment from any person before claiming from the Obligor under this Agreement and the Obligor waives all benefits of discussion and division. These waivers apply irrespective of any law or any provision of any Loan Document to the contrary.

7.1 Payment Immediately After Demand The Obligor’s liability to make a payment under this Agreement shall arise immediately after demand for payment has been made in writing on the Obligor which demand can only be made upon the occurrence and during the continuance of an Event of Default.

7.2 Right to Enforce Demands under this Agreement may be made from time to time, and the liabilities of the Obligor under this Agreement may be enforced, irrespective of:

(b) whether or in what order any security to which the Lender may be entitled in connection with any Loan Document is enforced.

7.5 Rights Cumulative No failure on the part of the Lender to exercise, nor any delay in exercising, any right or remedy under any Loan Document or this Agreement shall operate as a waiver, nor shall any single or partial exercise of any right or remedy prevent any further or other exercise or the exercise of any other right or remedy. Neither the taking of any judicial or extra-judicial proceeding nor the exercise of rights under any security held from the Obligor shall extinguish the liability of the Obligor to pay and perform its liabilities under this Agreement, nor shall the acceptance of any payment or security create any novation. No covenant, representation or warranty of the Obligor in this Agreement shall merge in any judgment. The rights and remedies provided in this Agreement are cumulative and do not exclude any rights and remedies provided by law or otherwise.

Any payment made by the Obligor under this Agreement shall be made without any deduction or withholding for or on account of tax and without any set-off or counterclaim of any kind. However, if the Obligor is required by law to deduct, withhold or pay any tax in respect of any payment under this Agreement, then (i) the Obligor shall pay additional sums under this Agreement as necessary so that, after making or allowing for all required deductions, withholdings and payments (including deductions, withholdings and payments applicable to additional sums payable under this Section), the Lender receives an amount equal to the sum it would have received had no deductions, withholdings or payments been required, (ii) the Obligor shall make any deductions, withholdings or payments required by law to be made by it and (iii) the Obligor shall timely pay the full amount required to be deducted, withheld or paid to the relevant governmental authority in accordance with applicable law.

8.3 Currency Indemnity If a judgment or order is rendered by any court or tribunal for the payment of any amount owing to the Lender under or in connection with this Agreement and the judgment or order is expressed in a currency (the “Judgment Currency”) other than the currency payable under or in connection with this Agreement (the “Agreed Currency”), the Obligor shall indemnify and hold the Lender harmless against any deficiency in terms of the Agreed Currency in the amount received by the Lender arising or resulting from any variation as between (a) the rate at which the Agreed Currency is converted into the Judgment Currency for the purposes of the judgment or order, and (b) the rate at which the Lender is able to purchase the Agreed Currency in accordance with normal banking practice with the amount of the Judgment Currency actually received by the Lender on the date of receipt. The indemnity in this Section shall constitute a separate and independent liability from the other liabilities of the Obligor under this Agreement, shall apply irrespective of any indulgence granted by the Lender, and shall be secured by any security held by the Lender from the Obligor.

8.4 Set-Off Each of the Lender and each of its affiliates is authorized at any time and from time to time to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by the Lender or such affiliate to or for the credit or the account of the Obligor against any and all of the liabilities of the Obligor which are due and payable under this Agreement. The rights of the Lender and its affiliates under this Section 8.4 are in addition to other rights and remedies (including other rights of set-off, consolidation of accounts and bankers’ lien) that the Lender or its affiliates may have.

CONTROL AGREEMENT

Customer No. ·

RBC Bank ACCOUNT CONTROL AGREEMENT

THIS ACCOUNT CONTROL AGREEMENT (this “Agreement”) is made and entered into as of July 1, 2011 by and among RBC BANK (USA), a North Carolina state banking corporation (“Bank”), ENERKEM CORPORATION (“Company”), and LIGHTHOUSE CAPITAL PARTNERS VI, L.P. (“Lender”).

A. In accordance with that certain loan agreement dated as of July 1, 2011 among Lender, Company and the other credit parties signatory thereto (as extended, renewed, amended, modified, supplemented and replaced from time to time, the “Credit Agreement”), Lender has agreed to make loans and extend other financial accommodations to Company.

B. A deposit account has been established with Bank (the “Account”) into which cash, checks, drafts, instruments, money orders, remittances, wire transfers and other items of value of Company or payable to Company are deposited or are to be deposited. The Account No. is 0000000000.

C. The parties desire to enter into this Agreement in order to set forth their relative rights and duties with respect to the Account and all funds on deposit therein from time to time.

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements hereinafter set forth, the parties hereto agree as follows:

1. Effectiveness. This Agreement shall take effect immediately upon its execution by all parties hereto and shall supersede any other blocked account or similar agreement in effect between all of the parties hereto with respect to the Account.

2. Security Interest. As collateral security for Company’s obligations to Lender under the Credit Agreement and the other loan documents referenced therein, Company hereby grants to Lender a present and continuing security interest in the following (“Collateral”): (i) the Account; (ii) all now existing and all hereafter arising contract rights and privileges in respect of the Account; (iii) all cash, checks, drafts, instruments, money orders, remittances, wire transfers and other items of value belonging to Company or payable to Company which are now deposited in the Account and which may in the future be paid to or deposited in the Account (“Receipts”); and (iv) the proceeds of or related to the Account and the Receipts — and in this Agreement reference to the Collateral or any one or more of the Account and the Receipts shall include proceeds. The security interest granted to Lender by Company in this paragraph 2 is supplemental to the security interest granted to Lender in the Credit Agreement or in one or more of the other loan documents referenced in the Credit Agreement, and is not in lieu thereof. In accordance with the Uniform Commercial Code in effect from time to time in the State whose laws govern this Agreement (“UCC”), Bank acknowledges and agrees that this Agreement constitutes notice of Lender’s security interest in the Collateral; provided, however, Bank does not warrant the existence, priority or perfection of such security interest.

3. Control of Account. The parties agree that this Agreement is, among other things, a “control” agreement under the UCC. Upon receipt by Bank of a notice purporting to be signed and sent by Lender in the form attached hereto as Exhibit A (a “Notice of Exclusive Control”), and without further consent by and without further notification to Company or any other person, Bank agrees to promptly comply with all notifications, orders, directives and instructions it receives from Lender (“Account Related Orders”), whether oral, written or electronic, with respect to the Account, including, without limitation, orders directing Bank to sell, transfer, redeem and take other action with respect to the property in the Account; provided, however, if Bank receives an order from any federal or state governmental authority (a “Government Order”) which conflicts with the Account Related Orders

received from Lender, Bank is authorized to comply with the Government Order in such manner as it or its legal counsel deems appropriate. Bank may rely upon any instructions from any person that Bank reasonably believes to be an authorized representative of Lender, provided, however, Bank shall not be obligated to comply with any instructions received from an “assignee” of Lender unless and until Bank shall have received written notice from Lender of such assignment.

4. Company’s Rights in Account. Bank may comply with all notifications, orders, directives and instructions originated by Company with respect to the Account until such time as Bank receives a Notice of Exclusive Control. Promptly upon Bank’s receipt of a Notice of Exclusive Control, Bank will not comply with any notifications, orders, directives or instructions originated by Company unless such notifications, orders, directives or instructions have been previously consented to in writing by Lender. For the purposes of this paragraph 4, Bank will have 2 business days after receipt of a Notice of Exclusive Control within which to implement such notice and Bank will be deemed to have acted “promptly” if Bank does not comply with notifications, orders, directives and instructions received from Company 2 business days after Bank’s receipt of a Notice of Exclusive Control.

5. Statements and Other Information. Upon Lender’s request in writing, Bank shall provide Lender with copies of the regular monthly bank statements provided to Company and such other information relating to the Account as shall reasonably be requested by Lender. To the extent Company has access to statements and information relating to the Account via on-line web access, Lender shall be given similar access upon written request therefor and payment to Bank of any costs and expenses associated with providing such service to Lender.

6. Fees. Upon demand by Bank, Company agrees to pay all usual and customary service charges, transfer fees and account maintenance fees (“Fees”) of Bank in connection with the Account. In the event Company fails to timely make a payment to Bank of any Fees for which demand for payment has been made, Bank may thereafter exercise its right of set-off against the Account and any other account of Company maintained with Bank in order to recover payment of the unpaid Fees — which set-off shall be superior to any security interests or liens of Lender. If for any reason Bank is unable to recover payment in full of the unpaid Fees from the Account and such other accounts through exercise of the right of set-off, including applicable law prohibiting set-off against any of such accounts, then at any time after a Notice of Exclusive Control has been received and implemented by Bank and prior to any termination of control by Lender, Lender shall pay the unpaid Fees to Bank within fifteen (15) business days of receipt of written demand for payment from Bank, provided (i) the unpaid Fees for which Bank demands payment from Lender, in the aggregate, do not exceed the average monthly Fee for the prior six (6) month period and (ii) demand for payment is received by Lender prior to the later of (A) the effective date of termination of this Agreement or (B) a date which is sixty (60) calendar days following the day on which Bank demanded payment from Company.

7. Uncollected Funds. Bank shall send to Lender and Company copies of all returned and dishonored Receipts within a commercially reasonable time following Bank’s receipt thereof. If any Receipt deposited in the Account is returned unpaid or otherwise dishonored, Bank shall have the right to both charge such returned or dishonored Receipt against the Account and any other account of Company maintained with Bank and to demand reimbursement therefor directly from Company. If for any reason Bank is unable to recover payment in full in the manner provided in the preceding sentence, then at any time after a Notice of Exclusive Control has been received and implemented by Bank and prior to any termination of control by Lender, Lender shall pay the amount of such returned or dishonored Receipt within fifteen (15) business days following the date Bank requests repayment thereof from Lender, provided that with respect to each returned or dishonored Receipt, (i) unless prohibited by applicable law, Bank has made demand for payment thereof on Company and Company has failed to pay such Receipt within five (5) business days following the date of Bank’s demand for payment and (ii) Bank’s request for repayment is made on Lender prior to the later of (A) the effective date of termination of this Agreement or (B) a date which is ten (10) business days following the business day on which the Receipt was actually received by Bank as a returned or dishonored Receipt and (iii) Lender has actually received funds from the Account prior to such demand and during Lender’s period of control. Lender’s obligation, if any, to pay on any returned or dishonored Receipt shall be limited to the amount of funds, if any, that Lender has actually withdrawn from the Account.

8. Set-off. Except to the extent expressly set forth in paragraphs 6 and 7 above, Bank agrees that prior to the effective date of a termination of this Agreement, Bank will not exercise or claim any right of set-off or recoupment against the Account and the Receipts. And, as to Lender, Bank hereby waives until the effective date of termination of this Agreement, any right of set-off and any right of recoupment which it may have against the Receipts.

9. Exculpation of Bank; Indemnification; Interpleader.

a. Bank undertakes to perform only such duties as are expressly set forth in this Agreement and to deal with the Account with the degree of skill and care that Bank accords to all accounts and funds maintained and held by it on behalf of its customers. Each of Company and Lender, severally, agree that Bank shall have no liability to either of them, and shall have no liability to any of their respective shareholders, directors, executives, officers, members, managers, partners, employees or agents, for any claims, losses, damages and costs and expenses that either, both or any combination of Company, Lender and their respective shareholders, directors, executives, officers, members, managers, partners, employees or agents may suffer or incur, either directly or indirectly, by reason of this Agreement or Bank’s performance or non-performance under this Agreement, unless occasioned by the gross negligence or willful misconduct of Bank. In no event shall Bank be liable for (i) any claims, losses, damages or costs and expenses resulting from computer malfunctions, computer viruses or system intrusions, interruption of communication facilities, labor difficulties, governmental actions affecting Bank and other similarly situated financial institutions, acts of war, terrorism or civil disobedience, acts typically falling within the concept of “Acts of God” or other causes beyond Bank’s reasonable control and (ii) indirect, special, consequential or punitive damages.

b. Company agrees to indemnify and hold harmless Bank and its shareholders, directors, executives, officers, employees and agents from and against any and all claims, losses, damages and costs and expenses suffered or incurred by any one or more of Bank and its shareholders, directors, executives, officers, employees or agents as a result of the assertion of any claim by any person arising out of, or otherwise related to this Agreement or any transaction conducted or service provided by Bank pursuant to this Agreement, other than those ultimately determined to be founded on gross negligence or willful misconduct of Bank.

c. If a bankruptcy or insolvency proceeding shall be instituted by or against Company, or if any third person should assert an adverse claim against any of the Collateral, whether such a claim arises by tax lien, execution, attachment, garnishment, levy, the claim of a trustee in bankruptcy or a debtor-in- possession, the claim of a competing lien creditor or otherwise, and Bank determines that its interests may be prejudiced or harmed in any respect if it takes any one or more of the actions contemplated by this Agreement with respect to the Collateral, then Bank, in addition to any other remedies it may possess under this Agreement, at law and in equity, may refrain from taking any of such actions and may interplead into the registry of an appropriate state or federal court situated in the State whose laws govern this Agreement as set forth below, all amounts then on deposit in the Account, all Receipts then in its possession and all Receipts received thereafter by Bank. The cost and expense of such interpleader shall be borne by Company, unless such interpleader shall be brought at Lender’s request, then at Lender’s cost and expense with reimbursement from Company. In the event of an interpleader in accordance with the foregoing sentences of this subparagraph, Lender’s security interest in the Collateral shall continue unaffected by the interpleader and Bank’s performance obligations under this Agreement shall xxxxx except for forwarding of Receipts received by it to the court in which such interpleader was brought. Upon such interpleader, Bank will be fully acquitted and discharged from all liability hereunder to Lender and Company for any obligation performable by Bank for the first time after the filing of such interpleader and Bank, at any time after the filing of the interpleader, may terminate all of its performance obligations under this Agreement by giving notice of such termination to Lender and Company fifteen (15) calendar days prior to the effective date of termination of its obligations, as specified in the notice. Upon receipt of notice from Bank that it is terminating its performance obligations under this Agreement, Lender may, in addition to its other rights and remedies and without terminating this Agreement, appoint another person to succeed to Bank’s position under this Agreement.

10. Receivable Contracts. Notwithstanding anything in this Agreement to the contrary, Company shall observe each and all of the terms and conditions of, and shall otherwise perform each and all of its obligations and responsibilities under all contracts and other agreements which give rise to the Receipts, or on which any of the Receipts are based, all in accordance with the terms of such contracts and other agreements (“Receivable Contracts”). Lender shall not have and Bank shall not have any obligation, responsibility or liability under any Receivable Contract by reason of or arising out of this Agreement, any other contract or other agreement, or the receipt by Lender or Bank of any payment or other thing of value relating to a Receivable Contract. In furtherance of the foregoing, but not in limitation thereof, Lender shall not be obligated and Bank shall not be obligated in any manner to (i) perform any of the obligations of Company under or pursuant to any Receivable Contract, (ii) make any payment under any Receivable Contract, (iii) make any inquiry as to the nature or sufficiency of any payment received relative to any Receivable Contract, or as to the sufficiency of any performance by any person under any Receivable Contract, or (iv) present or file any claim, or take any action to enforce any performance or payment under any Receivable Contract.

11. Termination; Survivability, This Agreement may be terminated by Company only upon delivery to Bank of a written notification of termination jointly executed by Company and Lender. This Agreement may be terminated by Lender at any time, with or without cause, upon its delivery of written notice thereof to both Company and Bank. This Agreement may be terminated by Bank at any time on not less than thirty (30) calendar days prior written notice delivered to both Company and Lender. Notwithstanding anything in this Agreement to the contrary, Lender and Company agree that Bank shall be entitled to Fees per item received pursuant to this Agreement for any period of time following termination that Bank continues to receive and deliver Receipts to Lender. Lender and Company shall have responsibility for notifying Company’s customers and any other persons who are parties to any of the Receivable Contracts of any address change. The provisions of paragraphs 2, 3 and 7 shall survive termination of this Agreement unless and until specifically released by Lender in writing. All rights of Bank under paragraphs 6, 7 and 9 shall survive any termination of this Agreement.

12. Irrevocable Agreements. Company acknowledges that the agreements made by it and the authorizations granted by it in paragraphs 2, 3, and 4 hereof are irrevocable and that the authorizations granted in paragraphs 2, 3, and 4 hereof are powers coupled with an interest.

LITIGATION AND ADMINISTRATIVE PROCEEDINGS

The Borrower purchased two (2) compressors from Canadian Xxxxxxx Holdings Ltd. in 2008. Canadian Xxxxxxx Holdings Ltd. delivered the compressors to the Borrower in June 2009. The compressors have never operated as per the Borrower specifications and Canadian Xxxxxxx Holdings Ltd. has not been able to repair or replace the compressors. The Borrower has therefore filed a claim in the amount of $1,242,014 against Canadian Xxxxxxx Holdings Ltd. to recover (i) the purchase price paid by the Borrower, (ii) the time related expenses for the installation, and (iii) the material and time expenses related for the replacement of the compressors. This claim has no significant impact on the Borrower’s business
