Upstream MLP / LLC Sector Overview

A publicly traded limited partnership owning oil & gas producing assets All excess cash flow is distributed quarterly to the unit holders MLP retains 15-30% of its cash flow to reinvest in the properties to maintain or grow its production Can grow through acquisition and drilling Can issue debt, equity and hedge Current oil & gas MLPs utilize 2-5 years of hedging to mitigate price volatility in stabilizing the distributions What is an Oil & Gas MLP?

Harvest properties need the right home - all properties are eventually harvest properties Lower cost of capital than a C-Corp as the yield is the cost of equity MLPs are not subject to entity level federal taxation Income and tax benefits flow through to the limited partners: cost/statutory depletion, IDC's L&WE depreciation 40-90%+ tax shield among peer group, Legacy >90% Appetite for yield in the marketplace Mature assets may have been neglected by their C-Corp owners focused on drilling Why Should MLPs Own Mature Producing Assets?

In 2006, 5 upstream MLP/LLCs went public, followed by Legacy in January 2007. Legacy's current market capitalization is approximately $710 million (4/16/2007). Upstream MLPs/LLCs Staged a Comeback in 2006

Drivers of New Upstream MLP / LLC Activity Long-Lived, Predictable Reserve Base Availability of Longer-Term Hedging Exploitation Strategy, Not Exploration Conservative Balance Sheet / Coverage Ratio Low decline rates / High R/P ratios High levels of PDP with predictable PUD opportunities Low development costs New upstream MLPs/LLCs focus on exploitation, rather than rely on exploration to support cash flow. Factory-like development of a well-known reserve base is ideal. Development of the longer-term hedging market has provided support to MLPs by facilitating visibility into production economics and available cash for distribution. Analysts are emphasizing more robust coverage ratios of distributions to distributable cash flow in new MLPs/LLCs, in order to support the sustainability of cash flows.

Significant Advantages of MLP without IDR Lower cost of capital than traditional MLP structure Common Unit distribution growth not burdened by IDRs to the GP Cost of equity equals market yield Simple and fair alignment of interests among all investors Investors share equally in all cash flows With significant ownership, management is strongly motivated to increase distributions Facilitates accretive acquisitions Acquisitions are more accretive at a given price Ability to use units as acquisition currency
