30. Provident Energy Trust, Calgary, (NYSE: PVX; Toronto: PVE-UN) may sell its 21.49% stake in the MLP Breitburn Energy Partners LP, Los Angeles, (Nasdaq: BBEP) and 95.55% indirect interest in BreitBurn GP LLC, the MLP's general partner.

In November, Breitburn Energy Partners completed a $1.45-billion acquisition of Quicksilver Resources Inc., giving Quicksilver a 32% interest and making it the largest shareholder. Prior to the deal, Provident's stake was 51%. Additionally, Breitburn made three other significant acquisitions in 2007 for assets in California, Florida and the Permian Basin totaling more than $210 million.

Canada is ending energy trusts' tax-free status in 2011.

Tom Buchanan, Provident president and chief executive, says, "BreitBurn's rapid growth has delivered considerable value to Provident and BreitBurn unit-holders, while our organizations have enjoyed a mutually beneficial relationship. However, as BreitBurn has funded its accretive growth through U.S. capital markets, Provident's ownership in the MLP has been reduced to approximately 22%. At this ownership level we view BreitBurn as an investment rather than a strategic growth vehicle for Provident. The government of Canada's income trust tax initiative is a further driver behind our thinking."

The market's perception of Provident as a hybrid upstream and midstream company may affect valuation as well, he says, and Provident may consider splitting its Canadian business units.

BreitBurn Energy Partners went public in October 2006 as an MLP. Current assets are in the Antrim shale in Michigan, the Los Angeles Basin in California, the Wind River and Big Horn basins in central Wyoming, the Sunniland Trend in Florida, the New Albany shale in Indiana and Kentucky, and the Permian Basin in West Texas.

Hal Washburn, co-CEO of BreitBurn Energy Partners, says, "Ultimately, BreitBurn's rapid growth, together with the changes in the Canadian tax law, have affected Provident's long-term strategy with respect to its BreitBurn interests. BreitBurn has benefited greatly from the Provident relationship, but we understand the need for them to consider monetization strategies for their BreitBurn interests."

Provident also owns a 96% indirect stake in BreitBurn Energy Co. LP (BEC), a separate U.S. subsidiary of Provident and not a part of BreitBurn Energy Partners. BEC holds assets in Los Angeles, Orange and Santa Barbara counties in California.

BreitBurn Energy Partners has a right-of-first-offer provision for BEC assets. The company was not able to agree on a price for the assets during the negotiation period, however, and Provident now plans to offer the assets via auction.

Washburn says, "The BEC oil and gas properties that Provident will take to market are assets we like and know well. They are some of the first assets we ever purchased but we made a clear decision not to put them into BBEP in 2006 given their state of development. It has always been our intention for BBEP to acquire the assets when the time and price was appropriate. However the current state of development of the assets resulted in differences in valuation expectations between BBEP and BEC/Provident, and management and the conflicts committee were unable to recommend that BBEP acquire these properties at the price offered.

"Furthermore, given the success of BBEP's acquisition efforts in 2007, the BEC properties are less relevant to our growth strategy now than they were at the IPO. We are a much larger company now and our growth is not as reliant on these assets being dropped down into BBEP as it was when we went public. For the next few years, we have very good organic growth opportunities in our existing properties, including the properties we purchased from Quicksilver."

Morgan Stanley is advisor to Provident.

75. NEW-Vaalco Energy Inc., Houston, (NYSE: EGY) is seeking strategic alternatives, including the possible sale of the company, following pressure from New York-based hedge fund Nanes Delorme Partners I LP and associated entities following stock underperformance in 2007.

Vaalco has assets in the Etame, Avouma and South Tchibala fields in Gabon, a 40% interest in Block 5 concession offshore Angola, a farm-in agreement to earn 25% interest in the 9-28b offshore license in the U.K. North Sea and minority interests in four wells in Texas. Production from the Gabon assets was 1.8 million barrels (500,000 barrels net) from July through September.

Nanes Delorme holds 8% of the common stock of Vaalco, making it the largest independent stockholder. The hedge fund feels the company is undervalued and suggests the entire company or its West African portfolio be sold.

In a letter to the Vaalco board, Nanes managing member Julien Balkany reports, "We are extremely frustrated by the major disconnect that exists between Vaalco's depressed stock price and the underlying value of its assets. We estimate the total net asset value of the company at approximately $420 million, which translates into approximately $7.12 per share and as of March 6, the shares closed as low as $4.45."

He adds that Nanes has lost confidence in Vaalco management and directors, due to its inability to move out of mature regions such as the North Sea, where it has been spending capital with no significant drilling discoveries, and the lack of any important reserves replacement.

"We strongly believe that Vaalco's stock price is significantly undervalued particularly when taking into account the value of similar M&A transactions in Africa where the company's core assets are located. In spite of record oil prices and a portfolio of high-quality oil and gas E&P properties, the company's stock price remains depressed and we believe is not appropriately valued by the public market."
