Delaware limited partnership (“Regency” and collectively, with the NGP Parties,
the “Parties”). Certain capitalized and other terms used in this Agreement are
defined in Schedule A hereto. Terms not otherwise defined shall have the
meanings ascribed to such terms in the Contribution Agreement.

WHEREAS, the NGP Parties collectively beneficially own 51,386,169 common units
representing limited partner interests in Eagle Rock Energy Partners LP, a
Delaware limited partnership (the “Partnership”) (the “Existing Units”);

WHEREAS, Regency, Regal Midstream LLC, a Delaware limited liability company and
a wholly owned subsidiary of Regency (“Regency Sub”) and the Partnership have
entered into that certain Contribution Agreement dated as of the date hereof
(the “Contribution Agreement”) pursuant to which the Partnership has agreed to
contribute the Midstream Business (as defined in the Contribution Agreement) to
Regency Sub; and

WHEREAS, as an inducement to and a condition to Regency’s willingness to enter
into the Contribution Agreement, each of the NGP Parties has agreed to enter
into this Agreement and vote its Securities (as defined herein) as described
herein;

NOW, THEREFORE, in consideration of the foregoing, the representations,
warranties, covenants and agreements contained in this Agreement and of other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties, intending to be legally bound, do hereby agree as
follows:

ARTICLE I

VOTING AGREEMENT

1.1 Agreement to Vote Covered Securities.

(a) During the term of this Agreement, at the Unitholder Meeting and every other
meeting of the unitholders of the Partnership that is called and at which action
is to be taken with respect to approval of the Contribution Agreement, and at
every adjournment or postponement thereof, and on every action or approval by
written consent of unitholders of the Partnership with respect to approval of
the Contribution Agreement, each NGP Party (solely in its capacity as a
unitholder, and not in any other capacity such as an officer or director of the
general partner of the Partnership) shall, vote its Securities in favor of
(i) the approval and adoption of the Contribution Agreement and the transactions
contemplated thereby, including the consummation of the Midstream Contribution
and (ii) any related matter that must be approved by the holders of common units
of the Partnership in order for the transactions contemplated by the
Contribution Agreement to be consummated in accordance with the terms of the
Contribution Agreement.

(b) During the term of this Agreement, each NGP Party (solely in its capacity as
a unitholder, and not in any other capacity such as an officer or director of
the general partner of

the Partnership) agrees not to vote any of its Securities in favor of, or
consent to, and will vote against and not consent to, the approval of any
(i) Alternative Proposal; (ii) reorganization, recapitalization, liquidation or
winding-up of the Partnership or any other extraordinary transaction involving
the Partnership; (iii) corporate action the consummation of which would
frustrate the purposes, or prevent or delay the consummation, of the
transactions contemplated by the Contribution Agreement; or (iv) other matter in
furtherance of any of the foregoing matters.

1.2 Other Voting Rights. Except as permitted by this Agreement, through the
Expiration Time, each NGP Party will continue to hold, and shall have the right
to exercise, all voting rights related to its Securities, subject to the
Existing NGP Voting Agreement (defined below).

1.3 Grant of Irrevocable Proxy. Subject to Section 1.1, during the term of this
Agreement, each NGP Party irrevocably appoints Regency and any designee of
Regency, and each of them individually, as such NGP Party proxy and
attorney-in-fact, with full power of substitution and resubstitution, to vote at
any meeting of unitholders of the Partnership at which any of the matters
described in Section 1.1 are to be considered through the Expiration Time, with
respect to its Securities as of the applicable record date, in each case solely
to the extent and in the manner specified in Section 1.1; provided, however,
that an NGP Party’s grant of the proxy contemplated by this Section 1.3 shall be
effective if, and only if, such NGP Party has not delivered to the Secretary of
the general partner of the Partnership, at least two (2) Business Days prior to
the applicable meeting, a duly executed irrevocable proxy card directing that
its Securities be voted in accordance with Section 1.1. This proxy, if it
becomes effective, is given to secure the performance of the duties of each NGP
Party under this Agreement, and its existence will not be deemed to relieve any
NGP Party of its obligations under Section 1.1. This proxy shall expire and be
deemed revoked automatically at the Expiration Time.

1.4 Existing NGP Voting Agreement. The Parties acknowledge that the provisions
of that certain Voting Agreement entered into as of May 3, 2011, by and among
NGP VIII and the Partnership (the “Existing NGP Voting Agreement”) have been
waived solely to the extent necessary to permit NGP VIII to comply with the
provisions of this Agreement pursuant to that certain letter agreement delivered
by the Partnership to NGP VIII on the date hereof (the “Existing NGP Voting
Agreement Waiver”).

execution, delivery or performance of this Agreement by such NGP Party, the

agreement, shareholders agreement or voting trust, to which such NGP Party is a
party or by which it or any of its properties or assets (including the
Securities) may be bound; (b) result in the creation of a Lien on any of such
NGP Party’s assets or property (including the Securities), except as created

any applicable Law, in each case, except for such violations, breaches, defaults
that would not, individually or in the aggregate, reasonably be expected to
prevent or delay consummation of the Midstream Contribution and the other
transactions contemplated by the Contribution Agreement and this Agreement or
otherwise reasonably be expected to prevent or delay Regency from performing its
obligations under this Agreement.

permitted by Section 4.1, such NGP Party is the owner of its Existing Units, all
of which are owned free and clear of any Lien and any other limitation or
restriction (including any restriction on the right to vote or otherwise dispose
of such units), other than pursuant to this Agreement. None of the Existing
Units are subject to any voting trust or other agreement or arrangement with
respect to the voting of such Existing Units, other than pursuant to this
Agreement and the Existing NGP Voting Agreement.

2.6 Total Partnership Common Units. Except for its Securities as of the date
hereof, such NGP Party does not beneficially own any (a) limited partner
interests or voting securities of Partnership; (b) securities of Partnership
convertible into or exchangeable for limited partner interests or voting
securities of Partnership; or (c) options or other rights to acquire from

convertible into or exchangeable for limited partner interests or voting
securities of Partnership.

Governmental Authority or any other Person that would reasonably be expected to
impair the ability of such NGP Party to perform his or its obligations hereunder
or consummate the transactions contemplated hereby. Such NGP Party is not
subject to any outstanding order, writ, injunction, judgment, decree or
arbitration ruling, settlement, award or other finding that would reasonably be
expected to impair the ability of such NGP Party to perform its obligations
hereunder or consummate the transactions contemplated hereby.

entering into the Contribution Agreement in reliance upon its execution,
delivery and performance of this Agreement.

COVENANTS

4.1 Transfer Restrictions. Each NGP Party agrees not to, during the term of this
Agreement, cause or permit any sale, transfer or other disposition (the
“Transfer”) of any of its Securities to be effected. Subject to Section 4.2, no
NGP Party shall not seek or solicit any Transfer. Each NGP Party agrees not to
deposit (or permit the deposit of) any of its Securities in a voting trust or
grant any proxy or enter into any voting agreement or similar agreement in
contravention of its obligations under this Agreement with respect to any

Agreement as in effect on the date of this Agreement.

4.3 Further Assurances. Regency and each NGP Party will execute and deliver, or
cause to be executed and delivered, all further documents and instruments and

ARTICLE V

MISCELLANEOUS

5.1 Directors and Officers. No Person executing this Agreement who is or becomes
during the term of this Agreement a director or officer of the general partner

this Agreement in such Person’s capacity as a director or officer.
Notwithstanding any provision of this Agreement to the contrary, nothing in this
Agreement shall (or shall require any NGP Party to attempt to) limit or restrict
any NGP Party in its capacity as a director or officer of the general partner of
the Partnership or any designee of any NGP Party who is a director or officer of

NGP Party’s commitments, arrangements and understandings pursuant to this
Agreement. For the avoidance of doubt, nothing herein shall prohibit any NGP

to reflect the execution and delivery of this Agreement and any other applicable
agreement entered into in connection with the Contribution Agreement or the
transactions contemplated thereby.

THE EXTENT THAT SUCH PRINCIPLES WOULD DIRECT A MATTER TO ANOTHER JURISDICTION.

courts of the State of Delaware and the Federal courts of the United States of
America located in the State of Delaware in respect of the interpretation and
enforcement of the provisions of this Agreement and of the documents referred to
in this Agreement, and in respect of the transactions contemplated hereby, and

the subject matter of such dispute and agree that mailing of process or other
papers in connection with any such action or proceeding in the manner provided
in Section 5.4 or in such other manner as may be permitted by Law shall be valid
and sufficient service thereof.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER
THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND
THEREFORE EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH
PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR
INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS
CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT

Agreement by facsimile or other customary means of electronic transmission
(e.g., pdf) shall be deemed binding for all purposes hereof, without delivery of
an original signature page being thereafter required. This Agreement may be
executed in one or more counterparts, each of which, when executed, shall be
deemed to be an original and all of which together shall constitute one and the
same document.

5.13 Severability. If any term or other provision of this Agreement is invalid,
illegal or incapable of being enforced by any rule of Law or public policy, all
other conditions and provisions of this Agreement shall nevertheless remain in
full force and effect so long as the economic or legal substance of the
transactions contemplated by this Agreement is not affected in any manner
materially adverse to any Party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the Parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the Parties as closely as possible in an acceptable manner to the end
that the transactions contemplated by this Agreement be consummated as
originally contemplated to the fullest extent possible.

5.14 Specific Performance. The Parties acknowledge and agree that each would be
irreparably damaged in the event that any of the provisions of this Agreement
were not performed in accordance with their specific terms or were otherwise
breached and that any non-performance or breach of this Agreement by any Party
could not be adequately compensated by money damages alone and that the Parties
would not have any adequate remedy at law. In the event of any breach or
threatened breach by any Party of any provisions contained in this Agreement,
the non-breaching Party shall be entitled (in addition to any other remedy that
may be available to it whether in law or equity, including monetary damages) to
seek (a) a decree or order of specific performance to enforce the observance and
performance of such provisions, and (b) an injunction restraining such breach or
threatened breach. Neither Party nor any other

Person shall be required to obtain, furnish or post any bond or similar
instrument in connection with or as a condition to obtaining any remedy referred
to in this Section 5.14, and each Party irrevocably waives any right it may have
to require the obtaining, furnishing or posting of any such bond or similar
instrument. The Parties further agree that they shall not object to the granting
of an injunctive relief on the basis that an adequate remedy at law may exist.

5.15 Other Definitional and Interpretative Provisions.

(a) The headings herein are for convenience of reference only, do not constitute
part of this Agreement and shall not be deemed to limit or otherwise affect any

Article, Section or Exhibit, such reference shall be to an Article of, a Section
of or an Exhibit to this Agreement unless otherwise indicated. Whenever the
words “include,” “includes” or “including” are used in this Agreement, they
shall be deemed to be followed by the words “without limitation.”

(b) The Parties have participated jointly in negotiating and drafting this
Agreement. In the event that an ambiguity or a question of intent or
