Plains All American Pipeline, L.P. (PAA) and certain subsidiaries entered into a Third Amendment to Credit Agreement (the "Revolver Third Amendment") and a Third Amendment to Fourth Amended and Restated Credit Agreement (the "Hedged Inventory Third Amendment"). These amendments replace Plains Midstream Canada ULC (PMCULC) with Plains Canada Liquid Pipelines ULC (PCLPULC) as a borrower under both credit facilities. All commitments to extend credit to PMCULC were terminated, and PMCULC was released from its obligations under the loan documents, including the release of liens on collateral for the Hedged Inventory Facility. PCLPULC has agreed to be bound by the terms of the applicable credit agreements as if originally a borrower and, for the Hedged Inventory Facility, joined the security documents and granted a security interest in the collateral. PAA's guarantee of borrower obligations under the Hedged Inventory Facility remains in full force and effect. The amendments did not change the aggregate lender commitments, maturity dates, pricing, covenants, or other material economic terms of either the Revolver or the Hedged Inventory Facility. The effectiveness of the amendments is conditional upon, among other things, the full payment of all outstanding loans and obligations owed by PMCULC to the administrative agent and lenders.
