NGP Capital Resources Company Realizes Gain from Portfolio Company Transaction

NGP Capital Resources Company announced the full realization of its investments in Rubicon Energy Partners, LLC (“Rubicon”).

On August 7, 2008, an undisclosed buyer completed the acquisition of the assets of Rubicon for $121.9 million. Concurrent with the sale, Rubicon repaid its Senior Subordinated Secured Multiple-Advance Term Loan (the “Term Loan”) in full. Subsequent to repayment of other debt and obligations, NGPC will receive its share of proceeds from the sale by virtue of its ownership interest in Rubicon. Rubicon was an independent oil and gas producer formed in August 2006 by Gary Sargent, Stephen Baker and NGPC to acquire and develop oil and gas properties in the Permian Basin, North Texas, and Oklahoma.

After retirement of the $5 million Term Loan and other obligations, the distribution of sale proceeds is expected to generate gross proceeds of approximately $18 million for NGPC and is expected to result in a pre-tax realized capital gain of approximately $14 million. The Company currently estimates that it will incur a tax liability related to the sale of approximately $3 million. Unrealized appreciation of $8 million had previously been recognized for NGPC’s ownership interest in Rubicon. The results of the realization will be recognized in the 3rd quarter of this year.

John Homier, President and Chief Executive Officer of NGPC, commented, “Our investment in Rubicon is another example of the successful relationships that NGPC is forging in the marketplace. We at NGPC have certainly enjoyed working with Gary and Steve to build Rubicon and we congratulate them on their exemplary execution of the business plan.”

Since NGPC’s IPO in November 2004, it has received over $289 million from the full or partial sale of investments in portfolio companies. Following the Rubicon transaction and additional funding on other investments, NGPC has committed and made available approximately $379 million to seventeen portfolio companies, of which approximately $315 million is currently outstanding.
