Item 1.01.      Entry into a Material Definitive Agreement.

Laser Acquisition
- -----------------

         On March 30, 2007, Eagle Rock Energy Partners, L.P., a Delaware limited
partnership ("Eagle Rock"), entered into a Partnership Interest Purchase and
Contribution Agreement ("Purchase and Contribution Agreement") with Laser
Midstream Energy II, LP, a Delaware limited partnership, Laser Gas Company I,
LLC, a Delaware limited liability company, Laser Midstream Company, LLC, a Texas
limited liability company, and Laser Midstream Energy, LP, a Delaware limited
partnership (the "Laser Acquisition"). Pursuant to the Purchase and Contribution
Agreement, the Company has acquired all of the non-corporate interests of Laser
Midstream Energy, LP, Laser Quitman Gathering Company, LP, and Laser Gathering
Company, LP for a total purchase price of approximately $136,800,000, consisting
of $110,000,000 in cash and 1,407,895 of Eagle Rock common units.

         The assets subject to the transaction include over 405 miles of
gathering systems and related compression and processing facilities in South
Texas, East Texas and North Louisiana. The Laser Acquisition is subject to
customary closing conditions, including obtaining regulatory approvals, and is
expected to close in late April.

Montierra Acquisition
- ---------------------

         On March 31, 2007, Eagle Rock ("Contributee") entered into a
Partnership Interest Contribution Agreement (the "Contribution Agreement") to
acquire certain fee minerals, royalties and working interest properties from
Montierra Minerals & Production, L.P., a Delaware limited partnership
("Montierra"), and NGP-VII Income Co-Investment Opportunities, L.P., a Texas
limited partnership ("NGP") for an aggregate purchase price of $127,600,000,
subject to price adjustments (the "Montierra Acquisition"). Moniterra and NGP
will receive as consideration a total of 6,400,000 Eagle Rock common units and
$6,000,000 in cash.

         The assets conveyed in the Montierra Acquisition include mineral acres
and interest in wells with net proved producing reserves of approximately 4.6
billion cubic feet of gas (unaudited) and 2.5 million barrels of oil
(unaudited). Eagle Rock anticipates that the Moniterra Acquisition will close by
the end of April, on satisfaction of various conditions, including obtaining
regulatory approvals.

Common Unit Purchase Agreement

         On March 30, 2007, Eagle Rock entered into a Common Unit Purchase
Agreement (the "Purchase Agreement") with several institutional purchasers in
connection with the private placement of 7,005,495 common units (the
"Offering"), resulting in gross proceeds of $127,500,000. The proceeds from the
Offering will be used to fully fund the cash portion of the purchase price of
the Laser Acquisition. Eagle Rock anticipates that the Offering will close
simultaneously with the Laser Acquisition.

         Eagle Rock also has agreed to file a registration statement with the
Securities Exchange Commission registering for resale the common units within 90
