Alliance Resource Partners, L.P. : Announces Transaction with White Oak Resources, LLC Supporting Development of Illinois Basin Coal Reserves

Alliance Resource Partners, L.P. (NASDAQ: ARLP) today announced that it has entered into a transaction with White Oak Resources, LLC and related entities (collectively "WOR") to support the development of a longwall mining operation currently under construction near McLeansboro, in Hamilton County, Illinois. The transaction features several components, including a preferred equity investment, the acquisition and leaseback of reserves and surface rights, a coal handling and services agreement, and a backstop equipment financing facility. Including an initial investment at closing of $69.5 million, ARLP currently expects its total investment in the project in a range of $400.0 - $525.0 million to be funded over the next three to four years. ARLP plans to utilize current cash balances, availability under its revolving credit facility and future cash flow from existing operations to fund its participation in the White Oak project.

"Strategically, Alliance's participation in this new, low-cost longwall operation further expands our investment in the growing Illinois Basin coal market," said Joseph W. Craft III, President and Chief Executive Officer of ARLP. "This venture allows ARLP to partner with the White Oak team in the development of this new mine and, if future market conditions warrant, the opportunity to participate in additional longwall mines within White Oak's extensive reserve base. Moreover, through the use of our MLP structure and strong balance sheet, we are able to generate attractive long-term recurring cash flows for Alliance."

White Oak Details

WOR is a privately-owned company which intends to develop and operate Mine No. 1 as a longwall mining operation to access approximately 200 million tons from the Herrin No. 6 coal seam. Construction of Mine No. 1 is underway and WOR currently anticipates longwall production will begin in the 2014 timeframe, depending on timing of slope construction and initial mine development. Once the longwall is in operation, WOR currently estimates Mine No. 1 will produce approximately 6.0 - 6.5 million tons of coal annually, which WOR intends to market in the domestic and export thermal coal markets.

Transaction Details

ARLP's investment in the White Oak project is comprised of the following components:

• Coal reserves - ARLP has committed $140.0 million to acquire and fund development of 200 million tons of coal reserves related to Mine No. 1. At closing, ARLP acquired approximately 100 million tons of leased and fee coal reserves and will acquire the remaining coal reserves in a series of follow-on transactions. ARLP will lease the acquired coal reserves back to WOR in exchange for a royalty income stream.
• Coal handling facilities, preparation plant and surface facilities - ARLP has committed up to $110.0 million to acquire surface rights and construct the coal handling, preparation plant, rail and coal loading facilities necessary to support Mine No. 1. ARLP will operate these surface facilities and serve as the sole provider of coal preparation and handling services and will receive a throughput fee on all feedstock coal. A portion of ARLP's $110.0 million commitment will be used by WOR to build the office, bathhouse and other surface facilities, which will be constructed and operated by WOR.
• Preferred equity investment - ARLP has committed to invest a minimum $150 million, up to a maximum $275 million, for a preferred equity interest in WOR. ARLP's preferred equity interest in WOR will have the right to distributions of essentially all distributable cash generated by WOR until ARLP has achieved a specified internal rate of return on its invested equity capital. Thereafter, ARLP will have an ongoing equity participation right to 20% to 40% of the distributable cash generated by WOR, depending on the total amount of equity capital provided by ARLP.

In addition, ARLP has agreed to provide WOR with a backstop equipment financing facility for up to $100 million, until such time as WOR is able to obtain third-party financing for the acquisition of equipment related to the development of Mine No. 1.

ARLP expects the transaction will be accretive to its earnings and distributable cash flow once longwall production begins at the new White Oak mine.

During 2011, ARLP is expecting to fund approximately $100.0 to $115.0 million of its commitments to the White Oak project, including its initial investment at closing. Reflecting the anticipated funding for the White Oak project and current estimates for existing operations, ARLP is adjusting guidance for 2011 total capital expenditures, including maintenance capital expenditures, to a range of $420.0 to $475.0 million.

ARLP was advised on this transaction by Stoll Keenon Ogden, PLLC, Vinson & Elkins, LLP, and Wells Fargo Securities, LLC. WOR was advised by Evercore Partners, Inc. and Shearman & Sterling, LLP.
