Vanguard Natural Resources, LLC on the closing of South Texas Acquisition

Vanguard Natural Resources, LLC has recently reported to the media that it has consummated its previously announced acquisition of natural gas and oil producing properties from an affiliate of the Lewis Energy Group (“Lewis”) for a purchase price of approximately $53.4 million in cash and Company units. The consideration included $32.04 million in cash and $21.36 million in Company units or 1,350,873 units determined based on the 20 day average closing price of the units on the NYSE Arca prior to the closing date of the transaction ($15.81). The purchase price is subject to final purchase price adjustments to be determined based on an effective date of June 1, 2008.

The acquired properties are located in the Dos Hermanos Field in Webb County, Texas, and have the following characteristics:

* Estimated proved reserves of 20 Bcfe * 65% proved developed * 5 year inventory of proved undeveloped locations based on drilling plan of six to eight wells per year * 98% natural gas * Natural gas BTU content of 1,150 * Reserve to production ratio of approximately 18 years

* Approximately 3,000 mcfe of net daily production

Scott W. Smith, President and Chief Executive Officer of Vanguard commented, “We are pleased to announce the closing of this acquisition of long-life natural gas properties and the establishment of an ongoing relationship with the Lewis Energy Group, the leading oil and gas producer in the Olmos trend of South Texas. Lewis has over 25 years of experience in exploration and development of this prolific gas producing trend and operates over 1,000 wells which currently produce approximately 67,000 mcf/d net to Lewis’ interest. With this transaction, Lewis has become one of our largest unitholders and we look forward to benefitting from their operational expertise with these properties and working with them as we jointly develop our multi-year inventory of proved undeveloped locations. This acquisition is immediately accretive to distributable cash flow and adds an additional geographic region to our property portfolio. In addition, as part of this transaction, we will assume attractive natural gas hedges covering approximately 85% of the estimated proved developed natural gas production through 2011. This hedging program ensures a stable cash flow from these assets and we therefore intend to recommend an increase in the quarterly distribution rate at our next Board meeting in August.”

The acquisition was funded with borrowings under Vanguard’s existing credit facility and cash on hand and through the issuance of 1,350,873 Vanguard units. These units are subject to a 180 day lock-up agreement.
