WHEREAS:




A.

Minco has entered into an agreement with Brookfield Properties (Vancouver) Ltd. to lease the premises located at Suite #2772, 1055 West Georgia Street, Vancouver, B.C., V6E 3P3 (the “Lease”); 




B.

Minco and East Energy have entered into a co-tenancy agreement dated July 1, 2006 and Minco and East Energy agree that this agreement shall replace all other existing agreement(s) in their entirety.




C.

And whereas the Minco and East Energy wish to enter into this Co-Tenancy Agreement of the Premises for a period of eight (8) years commencing April 1, 2007, and this Co-Tenancy Agreement shall be subject to any amendments as recommended and final approval by the Landlord.




NOW THEREFORE it is hereby agreed as follows:




1.

Minco agrees to allow East Energy to occupy an office space for its business purposes for the duration of the term of the Co-Tenancy Agreement, located on the twenty-seventh (27th) floor of the Royal Centre, 1055 West Georgia Street, Vancouver, British Columbia, V6E 3P3.  Such office space is more particularly outlined on the attached Schedule “1” and measures 1,118 square feet representing 24.3% of the allocated (excluding common areas) area of 4,593 square feet.  East Energy, however, may not assign its interest in the Co-Tenancy Agreement without the consent of Minco, which consent expressly may not be unreasonably withheld.




2.

East Energy agrees initially to pay to Minco rent in the amount of $5,130.86 per month  plus 6% GST ($307.95), representing 24.3% of the amount billed to Minco each month in advance on the first day of each and every month during the first twelve months of this Co-Tenancy Agreement, with the rent for any broken portion of a calendar month in which this Co-Tenancy Agreement terminates being pro-rated.  The monthly rent is for office rental only.  The monthly rent amounts after the initial twelve month period will be adjusted to reflect increases in rental payable under the lease. In addition, year end operating expenses and property tax adjustments also apply to 24.3%.  




East Energy agrees to reimburse Minco and East Energy for any special costs which are incurred at East Energy's request.




In the event of default by East Energy in carrying out any of the terms or conditions of this Co-Tenancy Agreement, East Energy agrees to grant Minco first charge over its assets until any outstanding rent or other payments due as a result of this Co-Tenancy Agreement have been paid in full.  




3.    

East Energy agrees to observe and perform all Minco's covenants, wherever applicable to East Energy, in the Lease apart from the payment of rent and additional rent to the Landlord.

6. 

Minco will add East Energy to its insurance policy as taken with its insurance provider with respect to commercial general liability and tenants liability and as an addition insured in respect of the Premises as to comply with the obligations of Minco under the Lease and shall be subject, as regards both the Landlord and Minco, to the same obligations and same limitations of liability with respect to damage, loss, or injury as are set out in the Lease between the Landlord and Minco.
