Section 5.05. Interpretation. When reference is made in this Agreement to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein,” “hereby” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The word “or” shall not be exclusive. Whenever used in this Agreement, any noun or pronoun shall be deemed to include the plural as well as the singular and to cover all genders. This Agreement shall be construed without regard to any presumption or rule requiring construction or interpretation against the party drafting or causing any instrument to be drafted.

Section 5.06. Counterparts. This Agreement may be executed in counterparts (which may be delivered by facsimile or other electronic transmission), each of which shall be deemed to be an original, but all of which, taken together, shall constitute one and the same agreement.

Section 5.07. Entire Agreement. This Agreement and, to the extent referenced herein, the Transaction Documents, together with the several agreements and other documents and instruments referred to herein or therein or attached hereto or thereto, constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, both oral and written, among the parties with respect to the subject matter hereof and thereof. Except for the representations and warranties expressly contained in Article 3, the Securityholder makes no express or implied representation or warranty with respect to the Securityholder or the Covered Shares, or otherwise.

Section 5.08. Governing Law; Consent to Jurisdiction; Waiver of Jury Trial.

(a) This Agreement shall be governed by, construed and enforced in accordance with the Laws of the Province of Alberta and the federal Laws applicable therein, without regard to any choice of law or conflict of laws principles thereof that would cause the application of the Law of any jurisdiction other than the Province of Alberta. Each Party irrevocably attorns and submits to the non-exclusive jurisdiction of the Alberta courts situated in the City of Calgary and waives objection to the venue of any proceeding in such court or that such court provides an inconvenient forum.

(b) EACH PARTY HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY HERETO (I) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SEEK TO ENFORCE THAT FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 5.09. Amendment; Waiver. Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement or, in the case of a waiver, by each party against whom the waiver is to be effective, but such waiver shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

Section 5.10. Remedies. The parties hereto agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any provision of this Agreement were not performed in accordance with their specific terms hereof or were otherwise breached and that it is accordingly agreed that, prior to termination of this Agreement, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to specific performance of the terms hereof, in addition to any other remedy at law or equity.

Section 5.11. Severability. If any term or other provision of this Agreement is held to be invalid, illegal or incapable of being enforced by any rule of law or public policy in any jurisdiction, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect and shall not be affected thereby, so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced in any jurisdiction, this Agreement will be reformed, construed and enforced in such jurisdiction so as to effect the original intent of the parties as closely as possible to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

Section 5.12. Successors and Assigns; Third Party Beneficiaries. Other than by the Securityholder to a transferee pursuant to a Permitted Transfer or any assignment, delegation or other transfer effected under the Merger Agreement, no party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of each other party hereto. No provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than the parties hereto and their respective heirs, executors, personal legal representatives, successors and permitted assigns. For the avoidance of doubt and without limiting Southern’s rights hereunder, Southern shall be a beneficiary of, and entitled to enforce, the rights of the Company under Section 2.03 (Proxy) to the extent not being enforced by the Company.

Section 5.13. Expenses. All costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense.

Section 5.14. Non-Recourse. Notwithstanding anything to the contrary herein or in any other documents delivered pursuant hereto, (a) this Agreement may be enforced only against, and any claim based upon, arising out of or related to a breach of this Agreement by the Securityholder may be made only against, the Securityholder (or in each case its Permitted Transferees), and (b) none of the Securityholder or its Affiliates shall have any liability for any liabilities of the parties hereto for any such claims (whether in tort, contract or otherwise) for breach of this Agreement or in respect of any oral representations made or alleged to be made in connection herewith (other than any such Permitted Transferee).

Section 5.15. Acknowledgment of Counsel.
