| 14.5 | Effect      of Transfer |
|------|-------------------------|

|   | (a) | No      consent of Landlord to a Transfer shall be effective unless given in      writing and executed by Landlord and no such consent shall be presumed by      any act or omission of Landlord or by Landlord’s failure to respond to any      request for consent or by Landlord’s accepting any payment of any amount      payable hereunder from any party other than Tenant. No Transfer and no      consent by Landlord to any Transfer shall constitute a waiver of the      necessity to obtain Landlord’s consent to any subsequent or other      Transfer. |
|--------|-----|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (b) | In      the event of any Transfer or any consent by Landlord to any Transfer,      Tenant shall not thereby be released from any of its obligations hereunder      but shall remain bound by all such obligations pursuant to this Lease for      the balance of the Term. If this Lease is renewed or extended by any      Transferee or if any Transferee exercises a right to lease additional      premises, pursuant to any right of Tenant contained in this Lease, each      Transferor shall be liable for all of the obligations of Tenant throughout      the Term as renewed or extended. |
|--------|-----|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (c) | Every      Transferee shall be obliged to comply with all of the obligations of      Tenant under this Lease, and any default of any Transferee shall also      constitute a default of Tenant hereunder. If this Lease is ever      disclaimed, repudiated or terminated by or on behalf of a Transferee      pursuant to any bankruptcy, insolvency, winding-up or other creditors’      proceeding, including, without limitation, any proceeding under the Bankruptcy and Insolvency Act      (Canada) or the Companies’ Creditors      Arrangement Act (Canada), or if this Lease is ever terminated by      Landlord as a result of any act or default of any Transferee, Tenant shall      nevertheless remain responsible for fulfilment of all obligations of      Tenant hereunder for what would have been the balance of the Term but for      such disclaimer, repudiation or termination, and shall upon Landlord’s      request enter into a new lease of the Premises for such balance of the      Term and otherwise on the same terms and conditions as in this      Lease. |

Upon request, Tenant shall make the corporate books      and records of Tenant and of any affiliate of Tenant available to Landlord      and its representatives for inspection in order to ascertain whether or      not there has been any Sale or Reorganization. Tenant acknowledges that,      in addition to Landlord’s rights under this Lease and at Law to withhold      consent to any Transfer, Landlord may withhold consent to any Sale or      Reorganization unless it is shown to Landlord’s reasonable satisfaction      that the financial strength of Tenant will not be adversely affected by      such Sale or Reorganization. |

|   | (b) | This      Section shall not apply to a Sale by Tenant if and as long as Tenant is in      occupancy of the Premises and is a corporation whose shares are listed and      traded on any recognized public stock exchange in Canada or the United      States. |
