West Williston Acquisition
As previously disclosed on September 5, 2013, Oasis Petroleum North America LLC, a wholly owned subsidiary of Oasis Petroleum Inc. (the
"
Company
") entered into a purchase and sale agreement (the "
Purchase Agreement
") with two undisclosed private sellers, pursuant to which the Company agreed to purchase 136,000 net acres in the
Williston Basin (the "
West Williston Acquisition
"). On October 1, 2013, the Company completed the West Williston Acquisition for aggregate consideration of approximately $1,479 million (the "
Purchase
Price
"), which is subject to customary post close adjustments.
In accordance with the Purchase Agreement, the Company funded
the Purchase Price of the West Williston Acquisition with proceeds from the Company's issuance of 6.875% senior unsecured notes due 2022 and borrowings under its revolving credit facility.
The foregoing description of the Purchase Agreement is a summary only and is qualified in its entirety by reference to the complete text of
