Item 2.01. Completion of Acquisition or Disposition of Assets.

EAC Acquisition
- ---------------

     On July 31, 2007,  Eagle Rock Energy  Partners,  L.P.,  a Delaware  limited
partnership ("Eagle Rock"), completed the acquisition of Escambia Asset Co., LLC
and Escambia Operating Company, LLC from AmGu Holdings,  LLC, a company owned by
unrelated  private  equity  funds,  for an  aggregate  purchase  price of $240.5
million including working capital adjustments, comprised of approximately $224.0
million in cash and 689,857 in Eagle Rock common units (the "EAC Acquisition").

     As previously  announced the assets conveyed in this transaction include 33
operated  wells in Escambia  County,  Alabama with net production of 3,300 Boepd
and proved reserves of 12.2 MMBoe, of which 89% is proved  developed  producing.
The  transaction  also  includes  two  treating  facilities  with  100  MMcfd of
capacity, one natural gas processing plant with 40 MMcfd of capacity and related
gathering systems.

Redman Acquisition
- ------------------

     On July 31, 2007,  Eagle Rock  completed the  acquisition  of Redman Energy
Holdings,  L.P., Redman Energy Holdings II, L.P. (Natural Gas Partners VII, L.P.
and Natural Gas Partners  VIII,  L.P.  portfolio  companies,  respectively)  and
certain assets owned by NGP Income Co-Investment  Opportunities Fund II, L.P. (a
Natural Gas Partners  affiliate)  (collectively,  "Redman") for a total purchase
price of $189.7 million  including  working capital  adjustments,  consisting of
$83.8  million in cash and  4,428,333  in Eagle Rock common  units (the  "Redman
Acquisition").

     The  assets  subject  to  this  transaction  include  76  operated  and  95
non-operated  wells mainly located in East and South Texas with a net production
of 1,810 Boepd and combined proved reserves of 8.3 MMBoe, of which 78% is proved
developed producing.

     One  or  more  Natural  Gas  Partners  private  equity  funds  directly  or
indirectly  owns a majority  of the equity  interests  in Eagle Rock and Redman.
Because of the  potential  conflict of interest  between the  interests of Eagle
Rock Energy G&P, LLC (the  "Company") and the public  unitholders of Eagle Rock,
the Board of Directors of the Company (the  "Board")  authorized  the  Company's
Conflicts Committee to review, evaluate, and, if determined appropriate, approve
the Redman  Acquisition.  The Conflicts  Committee,  consisting  of  independent
directors of the Company,  determined  that the Redman  Acquisition was fair and
reasonable to Eagle Rock and its public unitholders and recommended to the Board
that the  transaction be approved and  authorized.  In determining  the purchase
consideration for the Redman Acquisition,  the Board considered the valuation of
the  properties  involved in the  transaction,  the valuation of the units to be
offered as consideration in the transaction, and the cash flow of Redman.

     A press  release  issued by Eagle  Rock on July 31,  2007,  announcing  the
completion  of the EAC  Acquisition,  the Redman  Acquisition  and the  Offering
described  in  Item  3.02,  is  attached  hereto  as  Exhibit  99.1,  but is not
considered "filed" as part of this Item 2.01.

Item 3.02 Unregistered Sales of Equity Securities.

     On July 31, 2007,  Eagle Rock completed the sale of 9,230,770  common units
(the  "Offering")  to several  institutional  purchasers  in a private  offering
exempt from  registration  pursuant to Section 4(2) and  Regulation D (Rule 506)
under the  Securities  Act of 1933,  as amended.  The units were  purchased at a
price of $22.10  per unit  resulting  in gross  proceeds  of  $204,000,017.  The
proceeds from the Offering  were used to partially  fund the cash portion of the
purchase price of the EAC Acquisition and the Redman Acquisition.
