2.9 U.S. Securities Law Matters

The Parties agree that the Arrangement will be carried out with the intention that, and will use their commercially reasonable efforts to ensure that, all Consideration Shares issued pursuant to the Arrangement will be issued by the Purchaser in reliance on the exemption from the registration requirements of the U.S. Securities Act provided by Section 3(a)(10) thereunder and pursuant to exemptions from applicable state securities laws. In order to ensure the availability of the exemption under Section 3(a)(10) of the U.S. Securities Act and to facilitate the Purchaser’s compliance with other U.S. Securities Laws, the Parties agree that the Arrangement will be carried out on the following basis:

(a) the Court will be asked to approve the procedural and substantive fairness of the Arrangement;

(b) pursuant to Section 2.4, the Court will be advised of the intention of the Parties to rely upon the exemption from the registration requirements of the U.S. Securities Act provided by Section 3(a)(10) thereof with respect to the issuance of the Consideration Shares prior to the hearing required to approve the procedural and substantive fairness of the Arrangement to the Company Shareholders to whom the Consideration Shares will be issued;

(c) the Court will be advised prior to the hearing to approve the Interim Order that its approval of the Arrangement will be relied upon as a determination that the Court has satisfied itself as to the procedural and substantive fairness of the Arrangement to all Company Shareholders who are entitled to receive Consideration Shares pursuant to the Arrangement;

(f) each Person entitled to receive the Purchaser Shares upon exercise of Company Options will be advised that pursuant to the Arrangement such Purchaser Shares will not be issued by the Purchaser in reliance on the exemption from the registration requirements of the U.S. Securities Act provided by Section 3(a)(10) thereof as such exemption does not exempt the issuance of securities upon the delivery of the Purchaser Shares covered by such Company Options and, as

- 43 -

such, the underlying Purchaser Shares issuable in respect of the Company Options cannot be issued in the U.S. or to a person in the U.S. in reliance upon the exemption from registration provided by Section 3(a)(10) of the U.S. Securities Act and the Company Options may only be exercised pursuant to an effective registration statement or a then-available exemption from the registration requirements of the U.S. Securities Act and applicable state securities laws, if any;

(g) the Interim Order will specify that each Person entitled to receive Consideration Shares pursuant to the Plan of Arrangement will have the right to appear before the Court at the hearing of the Court to give approval to the Arrangement so long as they enter an appearance within a reasonable time;

The Purchaser and its counsel shall be given a reasonable opportunity to review and comment on the form and content of any such press release, recognizing that whether or not such comments are appropriate will be determined by the Company, acting reasonably.

After delivering such notice, provided that a Party is proceeding diligently to cure such matter and such matter is capable of being cured, no Party may terminate this Agreement until the earlier of the Outside Date and the expiration of a period of 15 business days from the date of such notice. If such notice is delivered prior to the date of the Company Meeting or the Purchaser Meeting, as the case may be, the Company (in the case of the Company Meeting) or the Purchaser (in the case of the Purchaser Meeting) may postpone or adjourn such meeting to the earlier of a date that is five business days prior to the Outside Date and the date that is 15 business days following the delivery of such notice.

(f) In the event that either the Purchaser or the Company terminates this Agreement pursuant to:

(i) Section 9.2(a)(ii)(C), and no Company Change in Recommendation has occurred, provided that the Purchaser Meeting has been held and the Purchaser Stockholder Approval has been obtained at the Purchaser Meeting, the Company shall reimburse the Purchaser in respect of the reasonable and documented expenses of the Purchaser’s third party Representatives incurred in respect of the Arrangement and this Agreement up to a maximum amount of $5,000,000; or

(ii) Section 9.2(a)(ii)(D), and no Purchaser Change in Recommendation has occurred, provided that the Company Meeting has been held and the Company Shareholder Approval has been obtained at the Company Meeting, the Purchaser shall reimburse the Company in respect of the reasonable and documented expenses of the Company’s third party Representatives incurred in respect of the Arrangement and this Agreement up to a maximum amount of $5,000,000,

and in each case such reimbursement shall be made by wire transfer in immediately available funds within three business days following such termination to an account specified by the Purchaser or the Company, as applicable. Each of the Company and the Purchaser hereby acknowledges that in the event that an expense reimbursement becomes payable pursuant to this Section 9.4(f) and is paid by the Company or the Purchaser, as applicable, as required by this Section 9.4(f), in the event that a Company Termination Payment or a Purchaser Termination Payment shall subsequently become due and payable under this Agreement, the amount of any expense reimbursement previously paid pursuant to this Section 9.4(f) shall be credited toward the obligation of the Company to pay the Company Termination Payment (in the case of an expense reimbursement previously paid by the Company) or the obligation

- 95 -

of the Purchaser to pay the Purchaser Termination Payment (in the case of an expense reimbursement previously paid by the Purchaser).

(g) Each Party acknowledges that the agreements contained in this Section 9.4 are an integral part of the transactions contemplated in this Agreement and that, without those agreements, the Parties would not enter into this Agreement. Each Party also acknowledges that all of the payment amounts set out in this Section 9.4 are payments in consideration for the disposition of rights of the Party entitled to receive such payments, and that the amounts set out in this Section 9.4 are payments of liquidated damages which are a genuine pre-estimate of the damages, which the Party entitled to such damages will suffer or incur as a result of the event giving rise to such payment and the resultant termination of this Agreement and are not penalties. Each Party irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive. For greater certainty, each Party agrees that,

(i) upon any termination of this Agreement under circumstances where the Purchaser is entitled to the Company Termination Payment and the Company Termination Payment is paid in full, such payment shall be the sole and exclusive remedy of the Purchaser in respect of the event giving rise to such payment and the Purchaser shall be precluded from any other remedy against the Company at Law or in equity or otherwise (including damages, injunctive relief or specific performance) and shall not seek to obtain any recovery, judgment, or damages of any kind, including consequential, indirect, or punitive damages, against the Company or any of its Subsidiaries or any of their respective directors, officers, employees, partners, managers, members, shareholders or affiliates or their respective Representatives in connection with this Agreement or the transactions contemplated hereby, and

(ii) upon any termination of this Agreement under circumstances where the Company is entitled to the Purchaser Termination Payment and the Purchaser Termination Payment is paid in full, such payment shall be the sole and exclusive remedy of the Company in respect of the event giving rise to such payment and the Company shall be precluded from any other remedy against the Purchaser at Law or in equity or otherwise (including damages, injunctive relief or specific performance) and shall not seek to obtain any recovery, judgment, or damages of any kind, including consequential, indirect, or punitive damages, against the Purchaser or any of its Subsidiaries or any of their respective directors, officers, employees, partners, managers, members, shareholders or affiliates or their respective Representatives in connection with this Agreement or the transactions contemplated hereby;

provided, however, that the foregoing limitations shall not apply in the event of fraud or a wilful breach by the Company or the Purchaser of their respective obligations under this Agreement (or for the avoidance of doubt, the Horizon Support Agreement), as applicable. For clarity, nothing contained in this Section 9.4(g) shall preclude the Company or the Purchaser from seeking injunctive relief

- 96 -

against the other party in accordance with Section 10.4 to restrain the breach or threatened breach of the covenants or agreements set forth in this Agreement or the Confidentiality Agreement (or for the avoidance of doubt, the Horizon Support Agreement) or otherwise to obtain specific performance of any of such acts, covenants or agreements, without the necessity of posting a bond or security in connection therewith.

(h) For the avoidance of doubt, in no event shall the Company be obligated to pay the Company Termination Payment on more than one occasion and in no event shall the Purchaser be obligated to pay the Purchaser Termination Payment on more than one occasion.

9.5 Amendment

Subject to the provisions of the Interim Order and Final Order, the Plan of Arrangement and applicable Laws, this Agreement and the Plan of Arrangement may, at any time and from time to time before or after the holding of the Company Meeting but not later than the Effective Time, be amended by mutual written agreement of the Parties, without further notice to or authorization on the part of the Company Shareholders, and any such amendment may without limitation:

(a) change the time for performance of any of the obligations or acts of the Parties;

(b) waive any inaccuracies or modify any representation or warranty contained herein or in any document delivered pursuant hereto;

(c) waive compliance with or modify any of the covenants herein contained and waive or modify performance of any of the obligations of the Parties; and

(d) waive compliance with or modify any mutual conditions precedent herein contained.

9.6 Waiver

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the Party or Parties to be bound by the waiver. A Party’s failure or delay in exercising any right or remedy under this Agreement will not operate as a waiver of such right or remedy. A single or partial exercise of any right or remedy will not preclude a Party from any other or further exercise of that right or the exercise of any other right or remedy.

10.3 Governing Law; Waiver of Jury Trial

This Agreement shall be governed, including as to validity, interpretation and effect, by the laws of the Province of British Columbia and the federal laws of Canada applicable therein. Each of the Parties hereby irrevocably attorns to the exclusive jurisdiction of the courts of the Province of British Columbia in respect of all matters arising under and in relation to this Agreement and the Arrangement. EACH PARTY TO THIS AGREEMENT HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY IN ANY ACTION PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF THE PARTIES IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.

10.4 Injunctive Relief

Prior to the termination of this Agreement in accordance with Section 9.2 and subject to Section 9.4(g), the Parties agree that irreparable harm would occur for which money damages would not be an adequate remedy at Law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, the Parties acknowledge and agree that, in order to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions hereof (including the obligations of the Purchaser pursuant to Section 2.12), the non-breaching Party will be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance, and the Parties shall not object to the granting of injunctive or other equitable relief on the basis that there exists an adequate remedy at Law. Prior to the termination of this Agreement in accordance with Section 9.2 and subject to Section 9.4(g), such remedies will not be the exclusive remedies for any breach of this Agreement but will be in addition to all other remedies available at Law or equity to each of the Parties. The Parties acknowledge and agree that the right of specific enforcement is an integral part of the transactions contemplated by this Agreement and without that right, neither the Company nor the Purchaser would have entered into this Agreement.

- 100 -

10.5 Time of Essence

Time shall be of the essence in this Agreement.

10.6 Entire Agreement, Binding Effect

This Agreement (including the exhibits and schedules hereto, the Company Disclosure Letter and the Purchaser Disclosure Letter) and the Confidentiality Agreement constitute the entire agreement, and supersede all other prior agreements and understandings, both written and oral, between the Parties, or any of them, with respect to the subject matter hereof and thereof and, except as expressly provided herein, this Agreement is not intended to and shall not confer upon any Person other than the Parties any rights or remedies hereunder.

10.7 No Liability

No director or officer of AcquireCo or the Purchaser shall have any personal liability whatsoever to the Company under this Agreement, or any other document delivered in connection with the transactions contemplated hereby on behalf of AcquireCo or the Purchaser. No director or officer of the Company shall have any personal liability whatsoever to AcquireCo or the Purchaser under this Agreement, or any other document delivered in connection with the transactions contemplated hereby on behalf of the Company.

10.8 Further Assurances

Each Party shall use commercially reasonable efforts to do all such things and provide reasonable assurances as may be required to consummate the Arrangement, and each Party shall provide such further documents or instruments as reasonably required by any other Party as necessary or desirable to effect the purpose of this Agreement and carry out its provisions, whether before or after the Effective Time.

10.9 Assignment and Enurement

The Purchaser may assign all or any part of its rights under this Agreement to, and its obligations under this Agreement may be assumed by, its wholly-owned Subsidiary, provided that if such assignment and/or assumption takes place, the Purchaser shall continue to be liable jointly and severally with such Subsidiary for all of its obligations hereunder and such Subsidiary shall remain at all times up to and including the Effective Date a wholly-owned Subsidiary of the Purchaser; and provided that such assignment and/or assumption does not result in any material Taxes being imposed on, or any adverse material Tax or other consequences in respect of Tax to any Company Shareholder, holder of Company Incentive Awards or the Company with respect to payments made under this Agreement. This Agreement shall not be otherwise assignable by any Party without the prior written consent of the other Party hereto. This Agreement shall be binding on and shall enure to the benefit of the Parties and their respective successors and permitted assigns.

10.10 Severability

If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the

- 101 -

transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

10.11 No Third Party Beneficiaries

The provisions of Section 5.11 and Section 5.15 are: (a) intended for the benefit of all present and former directors and officers of the Company and its Subsidiaries, as and to the extent applicable in accordance with their terms, and shall be enforceable by each of such Persons and his or her heirs, executors, administrators and other legal representatives (collectively, the “Third Party Beneficiaries”) and the Company shall hold the rights and benefits of Section 5.11 and Section 5.15 in trust for and on behalf of the Third Party Beneficiaries and the Company hereby accepts such trust and agrees to hold the benefit of and enforce performance of such covenants on behalf of the Third Party Beneficiaries; and (b) in addition to, and not in substitution for, any other rights that the Third Party Beneficiaries may have by contract or otherwise. Except for the rights of Third Party Beneficiaries under Section 5.11 and Section 5.15, which rights are hereby acknowledged and agreed by the Parties, this Agreement is not intended to confer any rights or remedies upon any Person other than the Parties.

10.12 Counterparts, Execution

This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument. The Parties shall be entitled to rely upon delivery of an executed facsimile or similar executed electronic copy of this Agreement, and such facsimile or similar executed electronic copy shall be legally effective to create a valid and binding agreement between the Parties.
