(b) The Corporation and Sellers shall have provided Purchaser with a reasonable opportunity to review and provide comments on a draft of the Estimate Statement prior to the date hereof, and the Estimate Statement will be subject to Purchaser's approval, which will not be unreasonably withheld or delayed.

(a) Within thirty (30) days of receipt of the Draft Statement, the Agents may notify Purchaser in writing of any objections the Agents may have to the Draft Statement and the Net Working Capital (an "Objection Notice"), which Objection Notice will set forth Sellers' calculation of the relevant amounts and a description of the nature and basis for the disagreements. If an Objection Notice is not so delivered to Purchaser, the Draft Statement shall become the "Closing Statement" for the purposes hereof, and the Net Working Capital set forth in the Draft Statement will be final, conclusive and binding on the Parties, and will not be subject to appeal, absent manifest error. If an Objection Notice is so delivered to Purchaser, then the Agents and Purchaser will forthwith and in any event within thirty (30) days, negotiate in good faith to resolve any such objections. In the event that the Agents and Purchaser are unable to resolve all such objections within thirty (30) days after Purchaser's receipt of such Objection Notice, the Agents and Purchaser will submit such remaining disagreements to Raymond Chabot Grant Thorton LLP, and if Raymond Chabot Grant Thorton LLP are unwilling or unable to act (e.g. due to any conflict of interest with either party), to any such other firm that the Parties may mutually agree upon (in either case, the "Independent Accountant"), and Purchaser and the Agents shall use commercially reasonable efforts to cause the determination of the dispute by the Independent Accountant to be made within thirty (30)days of the date of such submission. The Independent Accountant shall allow each of Purchaser and the Agents to submit, in writing, their respective positions regarding the Draft Statement, and Purchaser and the Agents shall have the right to submit additional documents, materials and other written information. The Independent Accountant shall consider such additional documents, materials and other written information. Any such other documents, materials or other information shall be copied to Purchaser and the Agents. Purchaser and the Agents shall jointly instruct the Independent Accountant that: (i) it shall act as an expert in accounting, and not as an arbitrator, to resolve the unresolved disputed items and amounts that were properly included in the notice of objection in accordance with this Agreement; (ii) it shall base their decision solely on the written submissions of Purchaser and the Agents, and not on independent review; and (iii) it may not assign a dollar value to any disputed item greater than the highest amount or less than the lowest amount claimed by Purchaser and the Agents, as applicable. The Independent Accountant's determination of the dispute will be final and binding upon the Parties and shall not be subject to appeal, absent manifest error. The Independent Accountant's determination of the Net Working Capital will be conclusive and binding on the Parties, absent manifest error, and will become the "Closing Statement" for purposes hereof.

(b) The Purchase Price will be adjusted based on the Closing Statement as follows:

(i) If the Net Working Capital set forth in the Closing Statement is greater than the Estimated Net Working Capital set forth in the Estimate Statement, an amount equal to the product of (A) the Discount and (B) the amount of such difference will be owed to Sellers by Purchaser (such amount, the "Sellers' Adjustment Amount") and the Sellers' Adjustment Amount shall be satisfied by Purchaser by issuing to Sellers, in the proportions set out in Exhibit 2.3, within ten (10) Business Days of the final determination of the Closing Statement, such number of Purchaser Shares equal to (A) the Sellers' Adjustment Amount, divided by (B) the five (5) trading day VWAP of a Purchaser Share immediately preceding the date of payment (rounded down to the nearest whole share).

12

(ii) If the Net Working Capital set forth in the Closing Statement is less than the Estimated Net Working Capital set forth in the Estimate Statement,an amount equal to the product of (A) the Discount and (B) the amount of such difference (such amount, the "Purchaser's Adjustment Amount") shall be satisfied by the Sellers by (i) reducing the First Milestone Payment by the Purchaser's Adjustment Amount; and (ii)reducing the Second Milestone Payment by such amount that the Purchaser's Adjustment Amount exceeds the First Milestone Payment, if applicable.

(c) Sellers, on the one hand, and Purchaser, on the other hand, will each bear the fees and expenses of their respective accountants, auditors and other professional advisors in preparing, reviewing or settling, as the case may be, the Draft Statement and the Closing Statement. In the case of a dispute and the retention of the Independent Accountant to determine such dispute, the fees and expenses of the Independent Accountant shall be allocated between Purchaser and Sellers' by the Independent Accountant in the same proportion that the aggregate dollar amount of the items unsuccessfully disputed or defended, as the case may be, by each (as finally determined by the Independent Accountant) bears to the total dollar amount of the disputed items. Purchaser, on the one hand, and Sellers', on the other hand, shall each promptly reimburse the other to the extent that the other party paid more than the amount so required pursuant to the preceding sentence. Such allocation of fees and expenses by the Independent Accountant shall be final, conclusive and binding on the parties.

13

(ii) in respect of the Second Milestone Payment, by issuing to Sellers, in the proportions set out in Exhibit2.3, such number of Purchaser Shares equal to (A) the Second Milestone Payment (if any), divided by (B) the five (5) trading day VWAP of a Purchaser Share immediately preceding the applicable Milestone Payment Date (rounded down to the nearest whole share).

(c) The Parties agree and acknowledge that the Milestone Payments relate to underlying goodwill of the Corporation, the value of which cannot reasonably be expected to be agreed upon by the Parties at the Closing Date.

Subject to Section 2.4 and Section 3.3(c), Purchaser will pay for its own fees and expenses and Sellers shall pay for their own fees and expenses as well as the fees and expenses of the Corporation which are, in each case, incurred in connection with the negotiation, preparation, execution and performance of this Agreement, the Transaction and the agreements contemplated by them, including the fees and expenses of legal counsel, investment advisers and accountants.

11.2 Appointment of Agents

(a) In order to administer efficiently the determination of certain matters under this Agreement, each Seller grants to each of [***], or any successor thereto appointed by the Sellers representing a majority of the Purchased Shares on the Closing Date, its respective irrevocable mandate to act as each such Seller's mandatary with respect to all matters under this Agreement and the other Transaction Documents (collectively, the "Agents" and each an “Agent”).

(b) Without limiting the generality of the foregoing, the Agents have full power and authority to make all decisions and take all actions relating to Sellers' respective rights, obligations and remedies under this Agreement and the other Transaction Documents including to receive and make payments, to receive and send notices (including notices of termination), to receive and deliver documents, to exercise, enforce or waive rights or conditions, to give releases and discharges, to seek indemnification on behalf of Sellers and to defend against indemnification claims of Purchaser. All decisions and actions taken by the Agents are binding upon all Sellers, and no Seller has the right to object, dissent, protest or otherwise contest the same.

(c) Purchaser is entitled to deal only with and, rely on decisions made by, the Agents in respect of all matters arising under this Agreement including to receive and make payments, to receive and send notices (including notices of termination), to receive and deliver documents, to exercise, enforce or waive rights or conditions, to give releases and discharges, to seek indemnification against Sellers or any one of them and to defend against indemnification claims of Sellers.

(d) All references in this Agreement and the other Transaction Documents to decisions and actions to be taken by Sellers or any one of them, as the case may be, are deemed taken by Sellers or any one of them, as the case may be, if such decisions or actions are taken

33

by the Agents. All references in this Agreement and the other Transaction Documents to decisions and actions to be taken by Purchaser and directed to Sellers or any one of them, as the case may be, are deemed directed to Sellers or any one of them, as the case may be, if such decisions or actions are directed by Purchaser to the Agents.

(e) In no event will Purchaser be held responsible or liable for the application or allocation of any monies paid to the Agents by Purchaser, and Purchaser will be entitled to rely upon any notice provided to Purchaser by the Agents or action taken by Agent acting within the scope of Agent's authority set out in this Agreement.

(f) Notwithstanding the foregoing, no payment, notice, receipt or delivery of documents, exercise, enforcement or waiver of rights or conditions, indemnification claim or indemnification defence will be ineffective by reason only of it having been made or given to or by a Seller directly if each of Purchaser and such Seller consent by virtue of not objecting to such dealings without the intermediary of the Agents.

(g) Each of the Parties acknowledges and agrees that each Agent is serving in that capacity solely for purposes of administrative convenience, and is not liable in such capacity for any of the obligations of any Seller, and Purchaser agrees that neither it, nor any of the Purchaser Indemnified Parties, will look to the assets of such Agent, acting in such capacity, for the satisfaction of any obligations to be performed by any Seller. Moreover, each of the Sellers acknowledges and agrees that he, she or it shall indemnify, on a several and not joint basis, each Agent and save them harmless in respect of any loss, damage or expense incurred by them as a result solely of acting as Agent under this Agreement, or any other Transaction Document or instrument delivered pursuant to this Agreement or contemplated hereby (collectively, the "Agents' Damages").

(h) A decision, act, failure to act, consent, or instruction of the Agents, including but not limited to an amendment of this Agreement, shall constitute (and the Parties may rely upon it as) a decision, act, failure to act, consent, or instruction of any applicable Seller and shall be (and the Parties may rely upon it as) final, binding and conclusive upon such Sellers and such Sellers' successors as if expressly confirmed and ratified in writing by such Sellers, and all defenses which may be available to any Seller to contest, negate or disaffirm the action of the Agents taken in good faith under this Agreement or the other Transaction Documents are waived.

(i) The Agents' Expense Fund will be used for the purposes of reimbursing the Agents for any Agents' Damages or other third party expenses pursuant to the Agreement and Transaction Documents. The Sellers will not receive any interest or earnings on the Agents' Expense Fund. The Agents are not providing any investment supervision, recommendations or advice and will not be liable for any loss of principal of the Agents' Expense Fund other than as a result of its gross negligence or willful misconduct. As soon as practicable following the completion of the Agents' responsibilities, the Agents will deliver the remaining balance of the Agents' Expense Fund to the Sellers in the proportions set out in Exhibit 2.3.

11.3 Sellers' Release

(a) Each of the Sellers, on its own behalf and on behalf of its successors and assigns (herein each referred to as a “Releasor”, which term includes any one or more of them) hereby unconditionally releases and forever discharges the Corporation, Purchaser and their respective associates and Affiliates, and their respective successors, assigns and predecessors, and their respective present and former officers, directors, shareholders, servants, agents and employees and their respective predecessors, successors, personal representatives and assigns (collectively, the “Releasees”) of and from all actions, causes of action, suits, debts, duties, demands, accounts, bonds, covenants,

34

contracts, covenants, judgments, proceedings and claims for injuries, losses, damages, interest, costs, indemnity, fines, penalties, legal and professional fees and assessments or amounts of any kind whatsoever (including any loss or damage not yet ascertained) that such Releasor ever had, now have or can, shall or may hereafter have for or by reason of or in any way arising out of any cause, matter or thing whatsoever existing up to the present time (collectively, the “Release Claims”); provided however that (i) nothing contained in this Section 11.3 shall operate to release any Party to this Agreement from any of its obligations under this Agreement, and (ii) this Section 11.3 shall not apply to any Release Claims that the Releasors, individually or collectively, may have against any of the Releasees relating to or arising out of: (a) all rights of the Releasors under this Agreement and the Transaction Documents; and (b) all rights of any Releasor, if any, to coverage under and to contribution or indemnification with respect to any applicable director's and officer's insurance policy of the Corporation.

(b) Each Releasor further covenants and agrees not to directly or indirectly, join, assist, instigate, aid or act in concert in any manner whatsoever with or encourage any other Person in the making of any claim or demand or in the bringing of any proceeding or action in any manner whatsoever against the Releasees or any of them with respect to the matters released or discharged pursuant to this Section 11.3 or with respect to which such Releasor agree not to make any claim or take any proceedings.

(c) Each Releasor further covenants and agrees not to make or continue any claim or complaint or initiate or continue any proceeding against any Person which might be entitled to claim, pursuant to the provisions of any applicable statute or otherwise, contribution, indemnity, damages or other relief over against the Releasees or any of them arising out of or in relation to the matters released or discharged pursuant to this Section 11.3.

(d) Each Releasor hereby represents, warrants and covenants that it has not assigned and will not assign to any other Person any of the Release Claims that such Releasor is releasing herein. Each Releasor confirms that no consideration given to it by any Releasee is an admission of liability or responsibility by any Releasee and any such liability or responsibility is expressly denied.

11.4 Additional Covenants of Purchaser.

(a) Purchaser Shares. The Purchaser Shares issuable on a Milestone Payment Date pursuant to Section 3.4 of this Agreement or upon the conversion of the Initial Secured Convertible Debentures or the Additional Secured Convertible Debentures, as the case may be, will, as of the date of issuance of such Purchaser Shares in accordance with Section 3.4, Section 4.2(a) or Section 4.2(b) of this Agreement, as applicable, be duly authorized and, issued upon receipt of payment or consideration therefor, validly issued as fully paid and non-assessable shares subject to all applicable Laws, including applicable securities Laws. On each respective Milestone Payment Date, Purchaser shall cause the Sellers or their nominee(s) to be entered upon the books of Purchaser as the holder of such Purchaser Shares and, as soon as practicable thereafter, Purchaser shall deliver or cause to be delivered to the Sellers share certificates or "Direct Registration Statements", as applicable, for such Purchaser Shares.

(b) Listing.

(i) Purchaser shall use commercially reasonable efforts to maintain the listing of the common shares in the capital of Purchaser issued on the Closing or issuable upon the conversion of the Initial Secured Convertible Debentures on the TSX (or such other stock exchange upon which the Common Shares will be listed, quoted or otherwise traded for the relevant period, if not on the TSX), for a period of at

35

least 5years from the date of this Agreement and take all reasonable steps necessary to ensure that any Purchaser Shares issued to the Sellers pursuant to the terms of this Agreement are listed for trading on the TSX (or such other stock exchange upon which the Common Shares are listed, quoted or otherwise traded for the relevant period, if not on the TSX),subject to applicable securities Laws and exchange regulations, in accordance with the requirements of this Agreement and will use commercially reasonable efforts to maintain Purchaser's status as a reporting issuer not in material default of the requirements of the Canadian securities Laws in all provinces of Canada.

(ii) Purchaser agrees to use its commercially reasonable efforts to obtain all necessary approvals to apply to list the Purchaser Shares issuable under this Agreement to satisfy the Milestone Payments or upon conversion of the Additional Secured Convertible Debentures to the Sellers on the TSX (or such other stock exchange upon which the Common Shares will be listed, quoted or otherwise traded for the relevant period, if not on the TSX) by the applicable issuance date. Purchaser shall take all reasonable steps necessary to satisfy any standard listing conditions imposed in any letter of the TSX (or such other stock exchange upon which the Common Shares will be listed, quoted or otherwise traded for the relevant period, if not on the TSX) granting conditional approval for the listing of the Purchaser Shares on such exchange. The Agents shall be given a reasonable opportunity to review and comment on the listing application for the Purchaser Shares and reasonable consideration shall be given to any comments by the Agents and their counsel. Purchaser shall discuss the status of the listing application with the Agents and shall promptly notify the Agents if there is any change in circumstance which is of such a nature that there is reasonable doubt that the Purchaser Shares will be listed.

11.5 Covenants regarding Tax Matters.

(a) After the Closing Date, Purchaser shall cause the Corporation to duly and timely make, prepare and file all Tax Returns required to be so made, prepared and filed by the Corporation for any Pre-Closing Tax Period for which Tax Returns have not been filed as of such date. Sellers and Purchaser shall co-operate fully with each other and make available to each other in a timely fashion such data and other information as may reasonably be required for the preparation of any such Tax Return and shall preserve such data and other information until the expiration of any applicable limitation period under any applicable Tax Laws. Any such income Tax Returns relating to the Corporation shall be submitted in draft form to Sellers at least fifteen (15) days before the date on which such Tax Returns are required by Law to be filed with the relevant Taxation Authority. The Agents shall, acting reasonably, have the right to review such Tax Returns and make any comments that it deems appropriate within fifteen (15) days following receipt thereof, which comments Purchaser may incorporate at its sole discretion, acting reasonably.

(b) Purchaser shall, at the request of a Seller receiving Purchaser Shares, make a joint election under subsection 85(1) or subsection 85(2), as applicable, of the Tax Act and the corresponding provisions of any applicable provincial tax statute at the amount elected by such Seller, subject to the limitations set forth in the Tax Act and the corresponding provisions of any applicable provincial tax statute. Purchaser shall not be responsible for the proper completion or filing of any election form, and such Seller will be solely responsible for the payment of any late filing penalty. Purchaser agrees to execute any properly completed election form and to forward such election (within twenty (20) days after the receipt thereof) to such Seller. With the exception of proper completion of Purchaser's section of the election form, execution of the election form and forwarding of the election form by Purchaser, within the stipulated time period, compliance with the

36

requirements for a valid election will be the sole responsibility of such Seller. Accordingly, Purchaser shall not be responsible or liable for any taxes, damages or expenses resulting from the failure by such Seller to properly complete any election form or to properly file such election form within the time prescribed and in the form prescribed under the Tax Act and the corresponding provisions of any applicable provincial tax statute.

11.6 Terminated Agreements.

The Corporation, together with AmorChem Holdings and all of Sellers who are party to the ROFR and Co-Sale Agreement, the Voting Agreement and the Investors' Rights Agreement (collectively, the "Terminated Agreements") hereby:

(a) agree that, effective as of the date hereof:

(i) the Terminated Agreements are hereby terminated in their entirety and of no further legal force and effect; and

(ii) all of the rights, benefits, obligations, liabilities, responsibilities and duties of the Corporation, AmorChem Holdings and the Sellers, pursuant to the Terminated Agreements are hereby terminated and shall not survive the termination of the Terminated Agreements pursuant to this Agreement, notwithstanding anything to the contrary contained in the Terminated Agreements;

(b) undertake to execute and deliver all such further documents and instruments and do all acts and things as are reasonably within their power as may be reasonably required for more effectively and completely carrying out or better evidencing or perfecting the termination of the Terminated Agreements, as the case may be.

11.7 Further Assurances.

Each Party will, from time to time, execute and deliver all such further documents and instruments and do all acts and things as the other Party may reasonably require to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement.

11.8 Public Announcements.

No Seller nor their respective representatives will make any public disclosure at any time concerning the matters set forth in this Agreement or the transactions contemplated hereby without the prior written consent of Purchaser, except if required by Law or rules of applicable stock exchanges, in which case they shall use commercially reasonable efforts to give Purchaser an opportunity to review and comment on any such disclosure in advance of public release. If and when Purchaser desires to make such public disclosure and if reasonably practicable in the circumstances, Purchaser shall use commercially reasonable efforts to give the Agents an opportunity to review and comment on any such disclosure in advance of public release, and Purchaser will accommodate the reasonable requests of the Agents with respect to the content thereof if communicated to Purchaser by the deadline set by Purchaser.

11.9 Benefit of the Agreement.

This Agreement will enure to the benefit of and be binding upon the respective heirs, executors, administrators, other legal representatives, successors and permitted assigns of the Parties.

A Party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a Party from any other or further exercise of that right or the exercise of any other right.

11.12 Assignment.

No Seller may assign its rights or obligations hereunder without the prior written consent of Purchaser, which consent will not be unreasonably withheld or delayed. Purchaser may not assign its rights or obligations hereunder without the prior written consent of the Agents, which consent will not be unreasonably withheld or delayed; provided, however, that Purchaser may assign any of its rights hereunder to (i) any Affiliate of Purchaser, (ii) any purchaser of (x) all or substantially all of the assets of Purchaser or the Corporation or (y) a majority of Purchaser's issued and outstanding voting securities, whether any such transaction is structured as a sale of shares, a sale of assets, an amalgamation or otherwise, or (iii) any lender providing financing to Purchaser, including equity investors. No assignment will relieve the assigning Party of any of its obligations hereunder.
