This Joinder Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original, but all such counterparts together shall constitute one and the same agreement.

This Joinder Agreement will be governed by, interpreted and enforced in accordance with, the laws of the Province of Alberta and the federal laws of Canada applicable therein.

IN WITNESS WHEREOF, the New Obligor has caused this Joinder Agreement to be executed and delivered by its duly authorized officer as of the date first above written.
