Natural Gas Price Deck Comparison Top 5 Banks

Of the 23 banks we spoke to: Only 14 are in the market for new deals Of those 14, 10 say that they are open to deals only if priced very well Comments heard across the board include: More selective on first lien names, needs to be middle of fairway, no to stretch Accommodate existing loans and not encouraged to grow book for new lenders until gets more direction in 2009 Can't see anything changing/improving until at least the second half 2009 (not like in past where each January gets a clean slate and a new budget) Concerned about next Borrowing Base Redetermination season and tight liquidity for some borrowers. Very high hurdles Even if return meets hurdle, needs ancillary business out of the blocks; leaning more to public deals since more capital markets opportunities Bank Market Update (as of 2008)

Where we are today: Hearing much of the same from last month Many lenders are conserving their capital to support only existing clients It is now an understood that pricing will go up Lenders with more levered borrowing bases being told that the price deck could severely limit availability in 2009 Beginning to see expected covenant breaches for 2 nd and 3 rd quarters Relative value continues to be a hot topic Our View on the 2009 Bank Market

What we are expecting from lenders still doing new money deals in 2009: 3 year is the max on E&P (and likely for midstream) due to tenor premiums Big unknown unused commitment fees due to tenor premiums: Euro banks are expecting % of drawn margin….37.5 to 50 bps may be the new floor. Price Decks for crude are down approximately 30% from September and 17% for natural gas. For next redetermination season, we expect significant decreases in borrowing bases…some property sets will be hit more than others. E&P up front expectations are in the range Pricing grids for E&P companies based on usage are up bps for new money deals (L for lenders that can actually do new money). Expect midstream to range from bps Upfront fee for E&P bps, Midstream bps upfront Undrawn fees are up. Other structural aspects have tightened across the board (i.e. more and tighter covenants).
