letter with National Bank of Canada (the “Bank”) dated August 12, 2011 as same
may be further amended, revised, modified, supplemented, restated or replaced
from time to time (the “Offering Letter”) wherein among other things, the
Corporation agreed to grant to the Bank by way of security for the Corporation’s
present and future indebtedness and liability to the Bank from time to time, an
undertaking to provide, at the Bank’s request, fixed charge security over, the
Corporation’s producing petroleum and natural gas properties (the “P&NG

NOW THEREFORE in consideration of the Bank agreeing to make advances to the
Corporation from time to time under the Offering Letter (as the same may be
amended, replaced or restated from time to time), the Corporation does hereby
represent, covenant and agree with the Bank as follows:

 

1. The Corporation represents and warrants to the Bank it is the beneficial
owner of the P&NG Properties and that the P&NG Properties are free and clear of
all claims, mortgages, liens, charges or encumbrances of any nature or kind
whatsoever other than Permitted Encumbrances (as defined in the Offering
Letter).

 

2. From time to time after the date hereof, the Corporation shall, at the
request of the Bank and as soon as practical after such request, provide to the
Bank a current list and description of the Corporation’s P&NG Properties and
other interests of the Corporation (the “Additional Interests”).

 

3. At the written request of the Bank, made in accordance with the Offering
Letter, the Corporation shall within five (5) Business Days (as defined in the

the nature of such fixed charge to be determined by the Bank but which, without
limitation, shall permit the Bank to add the same to Exhibit “1” to Schedule “A”
to the Debenture in which event such P&NG Properties and Additional Interests
shall without more, form part of the Specifically Mortgaged Property of the
Debenture and shall be subject to all of the terms and conditions thereof as if
the same had been so included in Exhibit “l” to Schedule “A” of the Debenture at
the time it was executed and delivered to the Bank.

 

4. In the event of any conflicts between the terms hereof and those of any other
agreements made between the Bank and the Corporation from time to time which
pertain to the P&NG Properties or the Additional Interests, those contained in
the Offering Letter shall govern and prevail unless the Bank and the Corporation
otherwise agree in writing.

and its successors and assigns and shall enure to the benefit of the Bank and
its successors and assigns.

IN WITNESS WHEREOF the Corporation has caused this agreement to be executed and
