The attached Loan Agreement contains representations and warranties made by the Corporation and certain of its affiliates to various counterparties for risk allocation purposes, and solely for benefit of those counterparties . National Instrument 51 - 102 allows reporting issuers to omit certain provisions of material contracts and readers are cautioned that statements made by the Corporation (and its affiliates) in the attached Loan Agreement and the related Schedules may be qualified (in whole or in part) by information redacted from the attached copy of the Loan Agreement and such related Schedules and Disclosure Letters, which information is not otherwise available to the public . Specifically, information which contains personal information as well as that regarding the name of certain counterparties and certain commercial terms (including those related to fees and certain thresholds in respect of permitted liens) have been redacted from this filing for confidentiality reasons and in consideration of the fact that disclosure of such redacted information may be materially prejudicial to the Corporation .
