aware of facts giving rise to a claim for indemnification pursuant to this Article 2, it will
provide notice thereof in writing to the Indemnifying Party specifying the nature of and specific
basis for such claim.



     (b) The Indemnifying Party shall have the right to control all aspects of the defense of (and
any counterclaims with respect to) any claims brought against the Indemnified Party that are
covered by the indemnification set forth in this Article 2, including, without limitation, the
selection of counsel, determination of whether to appeal any decision of any court and the settling
of any such matter or any issues relating thereto; provided, however, that no such settlement shall
be entered into without the consent (which consent shall not be unreasonably withheld, conditioned
or delayed) of the Indemnified Party unless it includes a full release of the Indemnified Party
from such matter or issues, as the case may be.



     (c) The Indemnified Party agrees to cooperate fully with the Indemnifying Party with respect
to all aspects of the defense of any claims covered by the indemnification set forth in Article 2,
including, without limitation, the prompt furnishing to the Indemnifying Party of any
correspondence or other notice relating thereto that the Indemnified Party may receive, permitting
the names of the Indemnified Party to be utilized in connection with such defense, the making
available to the Indemnifying Party of any files, records or other information of the Indemnified
Party that the Indemnifying Party considers relevant to such defense and the making available to
the Indemnifying Party of any employees of the Indemnified Party; provided, however, that in
connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact
thereof on the operations of the Indemnified Party and further agrees to maintain the
confidentiality of all files, records and other information furnished by the Indemnified Party
pursuant to this Section 2.4. In no event shall the obligation of the Indemnified Party to
cooperate with the Indemnifying Party as set forth in the immediately preceding sentence be
construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in
connection with the defense of any claims covered by the indemnification set forth in this Article
2; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and
pay for counsel in connection with any such defense. The Indemnifying Party agrees to keep any
such counsel hired by the Indemnified Party reasonably informed as to the status of any such
defense, but the Indemnifying Party shall have the right to retain sole control over such defense.



     (d) In determining the amount of any loss, cost, damage or expense for which the Indemnified
Party is entitled to indemnification under this Agreement, the gross amount of the indemnification
will be reduced by (i) any insurance proceeds realized by the Indemnified Party, and such
correlative insurance benefit shall be net of any incremental insurance premium that becomes due
and payable by the Indemnified Party as a result of such claim and (ii) all amounts recovered by
the Indemnified Party under contractual indemnities from third Persons. The Partnership hereby
agrees to use commercially reasonable efforts to realize any applicable insurance proceeds or
amounts recoverable under such contractual indemnities.

million.



     (b) No claims may be made against EPO for indemnification pursuant to Section 2.1(a)
unless the aggregate dollar amount of such claims for indemnification exceed $250,000, after such
time EPO shall be liable for the full amount of such claims, subject to the limitation of
Section 2.5(a).



     (c) In no event shall EPO have any indemnification obligations under this Agreement for claims
related to unknown Covered Environmental Losses made as a result of additions to or modifications
of Environmental Laws promulgated after the Closing Date.

until the three (3) business days following receipt by EPO of written notice from Enterprise Texas

     Section 4.1 Right of First Refusal.



     (a) Subject to Section 4.1(b), for so long as an EPD Entity controls EPO, (i) the
Operating Partnership hereby grants to EPO a right of first refusal on any proposed Transfer



9









 




(other than a grant of a security interest to a bona fide third-party lender or a Transfer to
another member of the Partnership Group) of any equity interest in the Subsidiaries of the
Operating Partnership or in the New Subsidiaries held by the Operating Partnership and (ii) the
Operating Partnership and each of the Current Subsidiaries hereby grants to EPO a right of first
refusal on any proposed Transfer (other than a grant of a security interest to a bona fide
third-party lender or a Transfer to another member of the Partnership Group) of any assets held by
the Partnership Group; provided, the foregoing shall not apply to Transfers of (i) any assets that
are not material to the conduct of the business and operations of the Operating Partnership or any

existing on the date hereof or retained by any third party in connection with the sale of such

or to cause such other EPD Entity to pay no less than 100% of the purchase price offered by a bona
fide, third-party prospective acquiror (a “Proposed Transferee”).




     (b) The Parties acknowledge that any potential Transfer of assets pursuant to this Article 4
(such assets, the “ROFR Assets”) shall be subject to, conditioned on and in compliance with
the terms and conditions in the Credit Facility and obtaining any and all necessary consents of
equityholders, noteholders or other securityholders, governmental authorities, lenders or other
third parties.



     (c) The Operating Partnership and each of the Current Subsidiaries hereby agree that it will
not consent to, and direct any of their officers or directors not to consent to, the Transfer of
any assets by any members of the Partnership Group who are not Parties to this Agreement in
violation of this Article 4 and will use its best efforts to require any other members of the
Partnership Group to comply with this Article 4 as if they were Parties to this Agreement.



     Section 4.2 Procedures.



     (a) If a member of the Partnership Group proposes to Transfer any ROFR Assets to a Proposed
Transferee (a “Partnership Acquisition Proposal”), then OLPGP shall promptly give written
notice (a “Partnership Disposition Notice”) thereof to EPO. The Partnership Disposition
Notice shall set forth the following information in respect of the proposed Transfer:




     (i) the name and address of the Proposed Transferee;




     (ii) the ROFR Asset(s) subject to the Partnership Acquisition Proposal;




     (iii) the purchase price offered by such Proposed Transferee (the
“Partnership Offer Price”);




     (iv) reasonable detail concerning any non-cash portion of the proposed
consideration, if any, to allow EPO to reasonably determine the fair value of such
non-cash consideration;




     (v) OLPGP’s estimate of the fair value of any non-cash consideration; and



10









 






     (vi) all other material terms and conditions of the Partnership Acquisition
Proposal that are then known to OLPGP.


To the extent the Proposed Transferee’s offer consists of consideration other than cash (or in
addition to cash), the Partnership Offer Price shall be deemed equal to the amount of any such cash
plus the fair value of such non-cash consideration. If EPO determines that it wishes to, or wishes
to cause another EPD Entity to, purchase the applicable ROFR Assets on the terms set forth in the
Partnership Disposition Notice (subject to the provisos set forth in Section 4.1(a), including
without limitation the requirement therein to pay 100% of the purchase price specified in the
Partnership Disposition Notice), it will deliver notice thereof to OLPGP within 45 days after
OLPGP’s delivery of the Partnership Disposition Notice (the “Acceptance Deadline”). Failure
to provide such notice within such 45-day period shall be deemed to constitute a decision not to
purchase the applicable ROFR Assets, and EPO shall be deemed to have waived its rights with respect
to such proposed disposition of the applicable ROFR Assets, but not with respect to any future
offer of such ROFR Assets. If the Transfer by the member of the Partnership Group to the Proposed
Transferee is not consummated in accordance with the terms of the Partnership Acquisition Proposal
within the later of (A) 180 days after the Acceptance Deadline, and (B) 10 days after the
satisfaction of all consent, governmental approval or filing requirements, if any, the Partnership
Acquisition Proposal shall be deemed to lapse, and the member of the Partnership Group may not
Transfer any of the ROFR Assets described in the Partnership Disposition Notice without complying
again with the provisions of this Article 4 if and to the extent then applicable.




     (b) If requested by the transferee Party, the transferor Party shall use commercially
reasonable efforts to obtain financial statements with respect to any ROFR Assets Transferred
pursuant to this Article 4 as required under Regulation S-X promulgated by the Securities and
Exchange Commission or any successor statute. EPO and the Partnership Group shall cooperate in
good faith in obtaining all necessary consents of equityholders, noteholders or other
securityholders, governmental authorities, lenders or other third parties.



ARTICLE 5

Preemptive Rights




     Section 5.1 Preemptive Rights in Current Subsidiaries.



     (a) If any Current Subsidiary proposes to sell any of its authorized limited liability company
interests, partnership interests, shares or other equity interests (“Capital Stock”) to any
Person in a transaction or transactions, as the case may be, other than (i) as consideration for
the acquisition of any other Person, assets or businesses, or (ii) any equity securities (including
convertible debt or warrants) issued in connection with a loan to or debt financing of the Current
Subsidiary, each of the Operating Partnership and EPO shall have the right to purchase, at the same
price per unit, percentage interest or share of such Capital Stock and upon substantially similar
terms and conditions, a pro rata number or percentage interest of such Capital Stock based on the
number or percentage interest of the Capital Stock as it owned immediately prior to such issuance.



11









 





     (b) In the event of a proposed transaction or transactions, as the case may be, that would
give rise to preemptive rights of the Operating Partnership and EPO under this Article 5, the
Operating Partnership shall provide notice to EPO no later than thirty (30) days prior to the
expected consummation of such transaction or transactions. Each Party possessing preemptive rights
hereunder shall provide notice of its election to exercise such rights within ten (10) Business
Days after delivery of such notice from the Operating Partnership. If any Party having a right to
purchase Capital Stock under the preceding sentence shall elect not to exercise such right, then
the other Party that has elected to exercise their rights with respect hereto shall have the right
to purchase such additional Capital Stock from the Party upon which such right was not exercised;
provided, however, that if, in connection with any proposed transaction or transactions giving rise
to rights hereunder, any Capital Stock remains from those that were available to the Parties
pursuant to their rights hereunder, no Party shall have any preemptive rights under this Article 5
and the proposed transaction or transactions shall be consummated without any exercise of
preemptive rights hereunder. In the event of a situation described in the preceding sentence in
which a Party elects not to exercise its preemptive rights with respect to a proposed transaction
or transactions, the Operating Partnership shall provide notice (the “Subsequent Notice”)
of such fact within five (5) Business Days following the receipt of all of the notices concerning
such elections from the Parties possessing such preemptive rights. Each Party possessing the right
to purchase the additional Capital Stock upon which the preemptive rights were not exercised shall
respond to this Subsequent Notice by sending a response notice with respect thereto within five (5)
Business Days after delivery of the Subsequent Notice. Failure of any Party to respond to such
Subsequent Notice with a notice stating the election of such Party to purchase such additional
Capital Stock shall be deemed to be an election not to purchase such Capital Stock, and the
proposed transaction or transactions shall be consummated without any exercise of preemptive rights
hereunder. Subsequent Notices shall also not be required if EPO has previously notified the
Operating Partnership, and the Operating Partnership has notified EPO, of their respective desires
not to purchase additional Capital Stock.



     (c) Each of the Operating Partnership and the Current Subsidiary agrees that it shall not
authorize or permit any direct or indirect Subsidiaries of the Current Subsidiaries to issue (by
initial issuance or by way of merger, consolidation or similar transaction) any of its Capital
Stock to any Person other than (i) to a direct or indirect wholly owned Subsidiary of such Current
Subsidiary, (ii) pro rata based on the then-current percentage interests owned by such other
Persons in a transaction in which the Current Subsidiary shall maintain its then-current percentage
interest, (iii) as consideration for the acquisition of any other Person, assets or businesses, or
(iv) any equity securities (including convertible debt or warrants) issued in connection with a
loan to or debt financing of the Current Subsidiary. Each Current Subsidiary agrees that it shall
not issue any of its Capital Stock, and shall not permit any of its Subsidiaries to issue any
Capital Stock, in violation of this Article 5.



ARTICLE 6

owned by Enterprise Texas.



ARTICLE 7

Miscellaneous




     Section 7.1 Choice of Law; Submission to Jurisdiction. This Agreement shall be
subject to and governed by the laws of the State of Texas, excluding any conflicts-of-law rule or
principle that might refer the construction or interpretation of this Agreement to the laws of
another state. Each Party hereby submits to the jurisdiction of the state and federal courts in
the State of Texas and to venue in Texas.



     Section 7.2 Notice. All notices or requests or consents provided for or permitted to
be given pursuant to this Agreement must be in writing and must be given by depositing same in the
United States mail, addressed to the Person to be notified, postpaid and registered or certified
with return receipt requested or by delivering such notice in person or by fax to such Party.
Notice given by personal delivery or mail shall be effective upon actual receipt. Notice given by

Agreement shall be sent to or made at the address set forth below or at such other address as such

     Section 7.4 Effect of Waiver or Consent. No waiver or consent, express or implied, by
any Party to or of any breach or default by any Person in the performance by such Person of its
obligations hereunder shall be deemed or construed to be a consent or waiver to or of any



13









 







other breach or default in the performance by such Person of the same or any other obligations
of such Person hereunder. Failure on the part of a Party to complain of any act of any Person or
to declare any Person in default, irrespective of how long such failure continues, shall not
constitute a waiver by such Party of its rights hereunder until the applicable statute of
limitations period has run.



     Section 7.5 Amendment or Modification. This Agreement may be amended, restated or
modified from time to time only by the written agreement of all the Parties; provided, however,
that no member of the Partnership Group may, without the prior approval of the Audit and Conflicts
Committee, agree to any amendment or modification of this Agreement that will adversely affect the
holders of Common Units. Each such instrument shall be reduced to writing and shall be designated
on its face an “Amendment,” “Addendum” or a “Restatement” to this Agreement.



     Section 7.6 Assignment; Third Party Beneficiaries. No Party shall have the right to
assign its rights or obligations under this Agreement without the prior written consent of all of
the other Parties. Each of the Parties hereto specifically intends that each entity comprising the
EPD Entities or the Partnership Entities, as applicable, whether or not a Party to this Agreement,
shall be entitled to assert rights and remedies hereunder as third-party beneficiaries hereto with
respect to those provisions of this Agreement affording a right, benefit or privilege to any such
entity.



     Section 7.7 Counterparts. This Agreement may be executed in any number of
counterparts with the same effect as if all signatory Parties had signed the same document. All
counterparts shall be construed together and shall constitute one and the same instrument.



     Section 7.8 Severability. If any provision of this Agreement or the application
thereof to any Person or circumstance shall be held invalid or unenforceable to any extent by a
court or regulatory body of competent jurisdiction, the remainder of this Agreement and the
application of such provision to other Persons or circumstances shall not be affected thereby and
shall be enforced to the greatest extent permitted by law.



     Section 7.9 Further Assurances. In connection with this Agreement and all
transactions contemplated by this Agreement, each Party agrees to execute and deliver such
additional documents and instruments and to perform such additional acts as may be necessary or
appropriate to effectuate, carry out and perform all of the terms, provisions and conditions of
this Agreement and all such transactions.



     Section 7.10 Withholding or Granting of Consent. Except as expressly provided to the
contrary in this Agreement, each Party may, with respect to any consent or approval that it is
entitled to grant pursuant to this Agreement, grant or withhold such consent or approval in its
sole and uncontrolled discretion, with or without cause, and subject to such conditions as it shall
deem appropriate.



     Section 7.11 Laws and Regulations. Notwithstanding any provision of this Agreement to
the contrary, no Party shall be required to take any act, or fail to take any act, under this



14









 







Agreement if the effect thereof would be to cause such Party to be in violation of any
applicable law, statute, rule or regulation.



     Section 7.12 Negation Rights of Limited Partners, Assignees and Third Parties. The
provisions of this Agreement are enforceable solely by the Parties, and no limited partner, member
or assignee of EPO, the Partnership, the Operating Partnership or the Current Subsidiaries or other
Person shall have the right, separate and apart from EPO, the Partnership, the Operating
Partnership or the Current Subsidiaries, to enforce any provision of this Agreement or to compel
any Party to comply with the terms of this Agreement.



     Section 7.13 No Recourse Against Officers or Directors. For the avoidance of doubt,
the provisions of this Agreement shall not give rise to any right of recourse against any officer
or director of any EPD Entity or any Partnership Entity.
