Revenues. The Partnership generates the majority of its revenues through 15-year, fee-based contractual arrangements with wholly-owned subsidiaries of Oasis Petroleum for midstream services as described in Note 1 — Organization and Nature of Operations. In addition, the Partnership sells the residue gas and NGLs recovered from its gas processing plants attributable to its third-party natural gas purchase agreements to Oasis Petroleum to market and sell to non-affiliated purchasers.

Oasis Petroleum has expressed substantial doubt about its ability to continue to operate as a going concern, and financial distress at Oasis Petroleum could have a material adverse effect on the Partnership’s results of operations (See Note 2 — Summary of Significant Accounting Policies — Risks and Uncertainties).

Expenses. Oasis Petroleum provides substantial labor and overhead support to the Partnership pursuant to a 15-year services and secondment agreement. Oasis Petroleum performs centralized corporate, general and administrative services for the Partnership, such as legal, corporate recordkeeping, planning, budgeting, regulatory, accounting, billing, business development, treasury, insurance administration and claims processing, risk management, health, safety and environmental, information technology, human resources, investor relations, cash management and banking, payroll, internal audit, tax and engineering. Oasis Petroleum has also seconded to the Partnership certain of its employees to operate, construct, manage and maintain the

Partnership’s assets. The expenses of executive officers and non-executive employees of Oasis Petroleum are allocated to the Partnership based on the amount of time spent managing its business and operations.
