Except as set forth on Schedule 2.7, Seller or PCKO has the right to transfer all of its right, title and interest in the leases and licenses included in the Assets and the assets of PCKO without any consent, and the transfer contemplated hereby will not affect their validity or enforceability. The Facilities (as hereinafter defined) have free and uninterrupted access to and from a dedicated public right-of-way through valid and subsisting easements, and such access is adequate for the use being made of the parcel being accessed as the Business is presently conducted. There are no imperfections of title, Liens, security interest, claims or other charges or encumbrances affecting the real property covered by any lease to be assigned to Buyer pursuant to this Agreement. “Pending” shall mean that the described action has commenced and is active as of the relevant date. “Threatened” shall mean that a relevant third party to the described

Seller has previously delivered to Parent and Buyer true and complete copies of the unaudited balance sheets of PCKO as of September 30, 2009 and the unaudited statements of income and cash flows of PCKO for the period from April 1, 2009 through September 30, 2009, including the notes relating thereto reflecting the financial position, results of operations and cash flows of PCKO (collectively the “Interim Financial Statements” and together with the Audited Financial Statements, the “Financial Statements”). The Financial Statements and all detailed schedules provided with respect thereto, including without limitation schedules with respect to accounts payable, accounts receivable, accrued liabilities, inventory, fixed assets, prepaid expenses and other assets and liabilities, are true and correct in all material respects and, taken as a whole, fairly present, in accordance with Canadian GAAP consistently applied, the consolidated financial position of PCKO as of the dates indicated and the consolidated results of operations and cash flows of PCKO for the periods then ended. There are no liabilities, contingent or definite, and no assets of PCKO that are not accounted for in the Financial Statements and such detailed schedules, except assets acquired and liabilities incurred after March 31, 2009 in the ordinary course of business and consistent with past practice and liabilities of a nature not required under Canadian GAAP to be accounted for in financial statements. Since March 31, 2009, no event, condition or circumstance has occurred, arisen or existed that requires or required, as the case may be, PCKO to (i) eliminate profits previously recognized for accounting purposes by PCKO or (ii) adjust downward the future profits to be recognized for accounting purposes by PCKO, with respect to any contract which has a fixed revenue component, in either case in order to comply with Canadian GAAP (including the percentage-of-completion method of accounting) and involving an amount exceeding CDN$25,000 in the aggregate.

     2.9 Customary Business Practice. Neither Seller nor PCKO nor any officer or director of Seller or PCKO acting on behalf of Seller or PCKO or, to Seller’s knowledge, any employee or agent of Seller or PCKO acting on behalf of Seller or PCKO has made or authorized the making of, directly or indirectly, any offer, payment or promise to pay any money or give anything of value to (a) any official or employee of a Governmental Body, (b) any political party or official thereof or any candidate for political office or (c) except entertainment usual or customary in the industry and gifts of nominal value, any customer, supplier, or competitor of Seller or PCKO, or any employee, officer or director thereof in order to assist such company in obtaining or retaining business for or with, or directing business to, any person, nor engaged in any other practice (including without limitation violation of any antitrust law or law regulating minority business enterprises), which would be likely to subject the Business to any damage or penalty in any civil, criminal or governmental litigation or proceeding or which would be likely to be used as the basis for termination or modification of any material contract, license or other instrument related to the Business to which Seller or PCKO is a party. For purposes hereof, the term “Governmental Body” shall mean any court or any foreign or domestic federal, provincial,

municipal or other governmental department, commission, board, bureau, agency or instrumentality.

     (d) by Buyer or Seller, if the Closing has not occurred on or before December 31, 2009; or

     (e) by Buyer in the event that Seller or any of its directors or representatives takes any of the actions prohibited or restricted by the provisions of Section 5.12 hereof in response to a proposal for an Alternative Transaction.

     Notwithstanding the above, this Agreement and the other Definitive Agreements shall be deemed to be terminated simultaneously if one or more of the Definitive Agreements are terminated; provided, that, the parties to this Agreement may mutually agree to complete the APA without the completion of either or both of this Agreement and the other Definitive Agreement. If this Agreement is terminated pursuant to (a) or (d) above, such termination shall be without liability of any party, or any director, officer, employee, agent, consultant or representative of such party, to any other party to this Agreement by Buyer or Seller, except as specifically provided in this Agreement. If this Agreement is terminated pursuant to (b) or (c) above, the rights and remedies granted hereby are cumulative and nonexclusive of any other right or remedy available to the terminating party at law or in equity. The parties agree that the Business and the Assets are unique in character and, if Seller defaults, damages suffered by Buyer may not be readily ascertainable. Accordingly, Seller agrees that Buyer, at its option, shall be entitled to the injunctive relief set forth in Section 14.7.

ARTICLE 14
MISCELLANEOUS

     14.1 Incorporation of Schedules and Appendices; Entire Agreement. The Appendices attached hereto and the Disclosure Schedules are an integral part of this Agreement and are incorporated herein by this reference and the specific references thereto contained herein. This Agreement and any other instruments or agreements delivered in contemplation of this Agreement, including the Confidentiality and Non-Disclosure Agreement between Seller and Parent executed on March 11, 2009 (the “Transaction Documents”), supersedes all prior discussions and agreements among the parties, including the Letter, with respect to the subject matter of this Agreement, and this Agreement, including the Appendices and Schedules hereto to be delivered in connection herewith, and the Transaction Documents and the other Definitive Agreements contain the sole and entire agreement among the parties hereto with respect to the subject matter hereof.

     14.2 Waiver. Any term or condition of this Agreement may be waived at any time by the party which is entitled to the benefit thereof; such waiver shall be in writing and shall be executed by the chairman, president or a vice president of each of the parties as applicable. A waiver on one occasion shall not be deemed to be a waiver of the same or any other matter on a future occasion.

     14.3 Amendment. This Agreement may be modified or amended only by a writing duly executed by or on behalf of all the parties hereto.

     14.4 Counterparts. This Agreement may be executed simultaneously in any number of counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same instrument.

     14.5 Headings. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

     14.6 Governing Law; Jurisdiction. Except as otherwise provided herein, this Agreement and all rights and obligations hereunder, including matters of construction, validity and performance shall be governed by the laws of the Province of Alberta and the federal laws of Canada applicable therein. Each of the parties to this Agreement hereby irrevocably submits to

the exclusive jurisdiction of the Courts of the Province of Alberta for and in respect of any proceedings relating to this Agreement, any agreement or instrument delivered pursuant to this Agreement or any other Definitive Agreement.

     14.7 Injunctive Relief. With respect to the matter described in the following sentence of this Section 14.7, the parties mutually agree that (a) if a violation or threatened violation of any covenant contained in this Agreement occurs by Seller, such violation or threatened violation may cause irreparable injury to the Buyer and the remedy at law for any such violation may be inadequate; and (b) the parties further agree that if Seller violates this Agreement it may be difficult to determine the entire cost, damage or injury which the Buyer would sustain. The parties agree that, upon any such breach or anticipated breach by Seller, Buyer shall have the right, in addition to any other rights that may be available to it, to obtain in any court of competent jurisdiction injunctive relief to restrain any such breach by Seller or to compel specific performance by Seller to cause Seller to effect the Closing after the affirmative vote of Seller’s shareholders approving the Special Resolution. The seeking or obtaining by Buyer of such injunctive relief shall not foreclose or in any way limit the right of Buyer to obtain a money judgment against Seller for any Damages to Buyer that may result from any breach by Seller of this Agreement. If this Agreement is terminated pursuant to Section 12.1 of the APA and the Fee, if payable, is paid as required by Section 12.2 of the APA, the injunctive relief provided by this Section 14.7 shall no longer be available.

     14.8 Risk of Loss. The risk of any loss, damage, impairment, confiscation or condemnation of the Assets or any part thereof shall be upon Seller at all times on or before the Closing Date. In any such event, Seller may either (a) repair, replace or restore any such property as soon as possible after its loss, impairment, confiscation or condemnation, or (b) if insurance proceeds are sufficient to repair, replace or restore the property, pay such proceeds to Buyer; provided, however, that in the event of damage to any substantial portion of the Assets, Buyer may terminate this Agreement with no penalty or liability to such Seller.

     14.9 Binding Effect. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns; provided, however, that this Agreement or any right or part hereunder shall not be voluntarily assigned by either party hereto without the prior written consent of the other party hereto, except that Buyer may assign its rights and obligations hereunder to a wholly owned, direct or indirect, subsidiary of Parent; provided, that, if such assignment takes place, Buyer and Parent shall continue to be jointly and severally liable to Seller for any default in performance by the assignee.

     14.10 Expenses. Seller shall pay its own legal and other professional expenses incurred in connection with the Letter, this Agreement and the transactions contemplated hereby, including the cost of the real property reports and Transfers for the property set forth on Schedule 5.8, and including, without limitation, the expenses of legal counsel and accountants engaged by them and other expenses incurred by Seller in connection herewith and not expressly allocated hereunder. Buyer shall be responsible for expenses of legal counsel and other representatives and agents engaged by Buyer, the expenses of its due diligence review (including expenses of any building and machinery inspections) and other expenses incurred by Buyer in connection herewith and not expressly allocated hereunder.

     14.11 Further Assurances. Seller, on the one hand, and Buyer, on the other hand, at any time after the Closing Date, will promptly execute, acknowledge and deliver any further deeds, assignments, conveyances and other assurances, documents and instruments of transfer, reasonably requested by the other parties and necessary to comply with the representations, warranties and covenants contained herein and will take any action consistent with the terms of this Agreement that may reasonably be requested by the other parties for the purpose of assigning, transferring, granting, conveying, vesting and confirming ownership in or to Buyer, or reducing to Buyer’s possession, any or all of the Assets.

     14.12 No Third Party Beneficiary. Any agreement to perform any obligation or pay any amount and any assumption of any obligation herein contained, express or implied, shall be only for the benefit of the parties hereto and their respective successors and permitted assigns as expressly permitted in this Agreement, and such agreements and assumptions shall not inure to the benefit of any obligee, whomever, it being the intention of the undersigned that no one shall be or be deemed to be a third party beneficiary of this Agreement other than parties that may have a right to indemnification under this Agreement.

     14.13 Knowledge of Seller. For the purposes of this Agreement, language limiting any representation or warranty to the knowledge of Seller or to Seller’s knowledge or similar terminology shall mean to the knowledge of senior management of Seller after due and diligent inquiry of employees of Seller having responsibility in the area of the representation being so qualified.

     14.14 Internal Reorganization. Notwithstanding anything else contained in this Agreement, prior to Closing, Seller may, at its sole option, undertake a short-form amalgamation involving one or both of Nextron Corporation and Redhill Systems Ltd., subsidiaries of Seller (the “Reorganization”), and shall promptly provide written notice to Buyer of the completion of the same. To the extent the Reorganization is completed, the provisions of this Agreement and all ancillary documentation contemplated by this Agreement will be amended mutatis mutandis to reflect such Reorganization.
