10

reasonable time, to commence and diligently and continuously conduct operations to perform any obligations requested, ordered or directed by the ERCB or other governmental body respecting environmental liabilities (a “Work Order”), and the ERCB or other governmental body refuses to approve a Licence Transfer as a result thereof, the other Party shall have the right to provide a written request to the first Party requesting them to satisfy any such Work Order and if the receiving Party of such notice fails within two business days to provide written notice of its intention and plan for satisfying a Work Order or then does not diligently and continuously conduct operations to satisfy a Work Order, than the other Party shall be entitled to enter upon and access the Assets to perform such obligations for and on behalf of the first Party without liability by the other Party to the first Party for trespass or otherwise, and the first Party shall reimburse the other Party for all reasonable costs, charges and expenses incurred by the other Party in the performance of such obligations, by providing payment thereof to the other Party within thirty (30) days of the other Party’s delivery to the first Party of an invoice for such costs, charges and expenses together with interest thereon at the Prime Rate from the date at which such costs, charges and/or expenses are incurred or paid by the other Party until such reimbursement is made.

The Goods and Services Tax registration number of Vendor is 862268982RT0001 and the Purchaser’s GST number is 121346357RT0001.  At Closing, Purchaser shall be solely responsible for all sales taxes, transfer taxes, fees, charges, levies or similar assessments, other than the Goods and Services Tax which may be imposed by any governmental authority and pertaining to its acquisition of the Assets or to the circulation and registration of the Specific Conveyances and shall remit any such amounts to the applicable governmental authority according to law.

11

2.8                               Letter of Credit

Purchaser shall, within two Business Days of the execution of this Agreement, forward the Deposit LC to the Escrow Agent, which shall be held and dealt with by the Escrow Agent in accordance with the terms and conditions of the Escrow Agreement.  If Closing occurs, Vendor and Purchaser shall jointly and irrevocably direct the Escrow Agent to release the Deposit LC to Purchaser undrawn, unless the Deposit LC has been drawn pursuant to section 2(e) of the Escrow Agreement, in which case Vendor and Purchaser shall jointly and irrevocably direct the Escrow Agent to pay the proceeds thereof to Vendor as partial payment of the Purchase Price.  If Closing does not occur, then with respect to the Deposit LC:

(a)                                 if Closing does not occur due to an exercise of the termination provisions of sections 3.1 or 11.5 on account of Purchaser’s closing conditions not being met through no act, default, or omission of Purchaser or on account of uncured Title Defects and Environmental Defects to which the provisions of section 11.5 are applicable; then Vendor and Purchaser shall jointly and irrevocably direct the Escrow Agent to return the Deposit LC, or the proceeds thereof if already drawn pursuant to section 2(e) of the Escrow Agreement, to the Purchaser, or

(b)                                 in all other circumstances, Vendor and Purchaser shall jointly and irrevocably instruct the Escrow Agent to draw on the Deposit LC, if not already drawn pursuant to section 2(e) of the Escrow Agreement, and pay the proceeds thereof to Vendor as liquidated damages, to compensate Vendor for expenses incurred in connection with the transaction contemplated herein and the delay or permanent impairment caused to Vendor’s efforts to sell the Assets and, in consideration for its retention of the proceeds of the Deposit LC, Vendor hereby waives any and all rights or additional remedies that may be available to it, at law or in equity, as a result of closing not occurring in such circumstances.  For clarity, Vendor’s retention of the proceeds of the Deposit LC is not a penalty but is a genuine pre-estimate by the Parties of the full limit of all damages that Vendor will suffer, having regard to the size of the Purchase Price, the amount of time between the date hereof and the proposed Closing Time, and the time and expense incurred and to be incurred by Vendor.

2.9                               Allocation of Purchase Price

The Parties shall allocate the Purchase Price as follows:

GST (5% of Tangibles and Miscellaneous Interests)

2.10                        Interest

At Closing, Purchaser shall pay to Vendor an amount equal to the interest that would have accrued on the Purchase Price, at the Prime Rate, calculated daily and not compounded, from and including the Adjustment Date to and including the day prior to the Closing Time,

12

which amount shall constitute an increase to the Purchase Price and shall be allocated to the Petroleum and Natural Gas Rights.
