        Section 9 - Term and Termination


        (1)       The Employee's employment under this Agreement shall commence on the Commencement Date and shall continue until terminated in accordance with this Section 9.


        (2)       Subject to Sections 9(3), (4) and (5), and notwithstanding any other provision contained herein to the contrary, the employment relationship between the Employee and OBUS arising out of this Agreement shall terminate upon forty-five (45) days notice being given to OBUS by the Employee or immediately upon notice being given to the Employee by
        OBUS.


        (3)       If OBUS is entitled to terminate this Agreement as the result of a Termination Event, OBUS shall not be required to compensate the Employee in respect of such termination or provide any period of notice in lieu of compensation with respect to such termination.


        (4)        Subject to Section 9(5), if this Agreement is terminated by OBUS at any time other than pursuant to Section 9(3), or if this Agreement is terminated by the Employee for Good Reason, the Employee shall be entitled to severance payment equal to twelve (12) months salary. Such severance compensation shall be paid to the Employee so as to
        maximize any reduction in income tax payable thereon as permitted by applicable laws. The severance payment as provided pursuant to this Section 9(4) shall include an amount equal to the value of the payment in lieu of benefits to which the Employee would otherwise have been entitled during the notice period.

        (5)        Notwithstanding Section 9(4), if there is a change of control of OBUS, as defined herein, and if this Agreement is terminated by OBUS at any time within one (1) year following the change of control other than pursuant to Section 9(3), the Employee shall be entitled to severance payment equal to twice that determined pursuant to Section
        9(4). Such severance compensation shall be paid to the Employee so as to maximize any reduction in income tax payable thereon as permitted by applicable law. For the purposes of this Section 9(5), “change of control” means any amalgamation, merger or other corporate reorganization which results in any change in the present effective voting control of OBUS, or will result in a change of the person or persons who own or control sufficient voting shares in OBUS to elect a
        majority of the directors of OBUS, or will result in a person acquiring sufficient voting shares in OBUS to elect a majority of the directors of OBUS.


        (6)        The Employee acknowledges and agrees that payment in lieu of notice in accordance with Section 9(4) or 9(5) shall be and is conclusively deemed to be reasonable compensation for termination of this Agreement and hereby waives any claim or potential claim that the Employee now has or may hereafter have, against OBUS for further severance
        compensation or notice other than that provided by the terms of this Agreement.


        
            	
                        (7)

                    	
                        The Employee confirms that:

                    


        


        
            	
                         

                    	
                        (a)

                    	
                        any breach of this Agreement or unauthorized disclosure of Confidential Information may result in irreparable harm to the Business of OBUS and considerable monetary damages to OBUS;

                    


        


        
            	
                         

                    	
                        (b)

                    	
                        the damages suffered by OBUS may be difficult to establish; and

                    


        


        
            	
                         

                    	
                        (c)

                    	
                        interim and permanent injunctions may be the only suitable remedy for OBUS;

                    


        


        but nothing herein shall in any way limit or restrict any other remedies available to OBUS at law or in equity including an action for damages.


        (8)        Termination of the Employee's employment with OBUS for any reason whatsoever shall not terminate the Employee's obligations under Sections 7, 8 and 10 of this Agreement.


        Section 10 - Non-Competition


        (1)       The Employee shall not, during the term of this Agreement, engage, hold an interest in or have any involvement, either directly or indirectly, in any business entity, venture or undertaking if such would materially interfere with or conflict with the Employee's duties and obligations to OBUS as provided for under this Agreement, provided that the
        acquisition of a non-control position in publicly traded companies will not contravene this Section.


        (2)       The Employee shall not, during the term of this Agreement, and for a period of one (1) year following the termination or expiration of this Agreement, either individually or in partnership or jointly or in conjunction with any person, firm or corporation as principal, employee, partner, director or as a shareholder or investor (if actually
        involved in the management of a business which is competitive with the Business of OBUS or its Affiliates) carry on or be engaged in any business which is directly competitive with the Business of OBUS or its Affiliates.


        (3)       The parties agree that all of the restrictions contained in Subsection 10(2) hereof are reasonable and valid, and that all defences to the strict enforcement thereof by OBUS are hereby waived by the Employee.

        (4)       The Employee agrees that the remedy at law for any breach by the Employee of the provisions of this Section 10 may be inadequate and that in the event of such breach, OBUS may make an application to a court of competent jurisdiction for an order granting OBUS temporary, permanent or both kinds of injunctive relief against the Employee, without
        the necessity of proving actual damage to OBUS.


        (5)       The Employee agrees that any waiver by OBUS of a breach of this Agreement by the Employee shall only be a waiver with respect to the particular breach giving rise to the waiver.
