Other Events. On September 13, 2007, Eagle Rock Energy Partners, L.P. ("Eagle Rock" or the "Partnership"), pursuant to its stated strategy of mitigating its commodity price exposure and reducing the volatility in its cash flows, entered into a WTI crude oil swap for 2008 on 80,000 barrels per month at a swap price of $73.90. Eagle Rock also entered into WTI crude oil collars to reverse out-of-the-money collars for 2008 production of the same 80,000 barrels per month, at a cost of approximately $9.1 million. The combined impact of these two transactions was to raise Eagle Rock's floor on those volumes by $23.90 per barrel while at the same time raising its cap by $6.51 per barrel to its swap price of $73.90. SIGNATURE Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
