Item 14.   Indemnification of Directors and Officers.
 
The section of the prospectus entitled “Description of Material Provisions of Our Partnership Agreement — Indemnification” is incorporated herein by this reference. Reference is also made to the Underwriting Agreement filed as Exhibit 1.1 to this registration statement. Subject to any terms, conditions or restrictions set forth in the partnership agreement, Section 17-108 of the Delaware Revised Uniform Limited Partnership Act empowers a Delaware limited partnership to indemnify and hold harmless any partner or other person from and against all claims and demands whatsoever.
 
Section 18-108 of the Delaware Limited Liability Company Act provides that, subject to such standards and restrictions, if any, as are set forth in its limited liability company agreement, a Delaware limited liability company may, and shall have the power to, indemnify and hold harmless any member or manager or other person from and against any and all claims and demands whatsoever. The First Amended and Restated Limited Liability Company Agreement of DEP Holdings, LLC provides for the indemnification of (i) a present or former member of the Board of Directors of DEP Holdings, LLC or any committee thereof, (ii) a present or former member, (iii) a present or former officer of DEP Holdings, LLC or (iv) a person serving at the request of DEP Holdings, LLC in another entity in a similar capacity as that referred to in the immediately preceding clauses (i), (ii) or (iii) (each person in clauses (i), (ii), (iii) and (iv), a “General Partner Indemnitee”) to the fullest extent permitted by law, from and against any and all losses, claims, damages, liabilities, (joint or several), expenses (including reasonable legal fees and expenses), judgments, fines, penalties, interest, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any such person may be involved, or is threatened to be involved, as a party or otherwise, by reason of such person’s status as a General Partner Indemnitee; provided, each case the General Partner Indemnitee shall not be indemnified if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the General Partner Indemnitee is seeking indemnification, the General Partner Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the General Partner Indemnitee’s conduct was unlawful. Any indemnification pursuant to these provisions shall be made only out of the assets of DEP Holdings, LLC. DEP Holdings, LLC is authorized to purchase and maintain insurance, on behalf of the members of its Board of Directors, its officers and such other persons as the Board of Directors may determine, against any liability that may be asserted against or expense that may


II-1


 

 
be incurred by such person in connection with the activities of DEP Holdings, LLC, regardless of whether DEP Holdings, LLC would have the power to indemnify such person against such liability under the provisions of its limited liability company agreement.
 
Item 15.   Recent Sales of Unregistered Securities.
 
On September 29, 2006, in connection with the formation of the partnership, Duncan Energy Partners L.P. issued (1) to DEP Holdings, LLC, the 2% general partner interest in the partnership for $60 and (2) to Enterprise Products Operating L.P., the 98% limited partner interest in the partnership for $2,940, in an offering exempt from registration under Section 4(2) of the Securities Act of 1933. There have been no other sales of unregistered securities within the past three years.

Item 17.   Undertakings
 
The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.
 
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such

II-3


 

indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction of the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
 
The undersigned registrant hereby undertakes that:
 
For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective.
 
For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
The registrant undertakes to send to each limited partner at least on an annual basis a detailed statement of any transactions with DEP Holdings, LLC or its affiliates, and of fees, commissions, compensation and other benefits paid, or accrued to DEP Holdings, LLC or its affiliates for the fiscal year completed, showing the amount paid or accrued to each recipient and the services performed.
 
The registrant undertakes to provide to the limited partners the financial statements required by Form 10-K for the first full fiscal year of operations of the partnership.

Exhibit 5.1
[Andrews Kurth LLP Letterhead]
January 23, 2007
Duncan Energy Partners L.P.
1100 Louisiana Street, 10th Floor
Houston, Texas 77002
Gentlemen:
     We have acted as special counsel to Duncan Energy Partners L.P., a Delaware limited partnership (the “Partnership”), in connection with the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the offering and sale of up to an aggregate of 14,950,000 common units representing limited partner interests in the Partnership (the “Common Units”) by the Partnership.
     As the basis for the opinion hereinafter expressed, we have examined such statutes, including the Delaware Revised Uniform Limited Partnership Act (the “Delaware Act”), regulations, corporate records and documents, certificates of corporate and public officials, and other instruments and documents as we have deemed necessary or advisable for the purposes of this opinion. In making our examination, we have assumed that all signatures on documents examined by us are genuine, the authenticity of all documents submitted to us as originals and the conformity with the original documents of all documents submitted to us as certified, conformed or photostatic copies.
     Based on the foregoing and on such legal considerations as we deem relevant, we are of the opinion that the Common Units, when issued and delivered on behalf of the Partnership against payment therefore as described in the Partnership’s Registration Statement on Form S-1 (Commission File No. 333-138371), as amended, relating to the Common Units (the “Registration Statement”), will be duly authorized, validly issued, fully paid and non-assessable.
     We express no opinion other than as to the federal laws of the United States of America and the Delaware Act (including the statutory provisions, all applicable provisions of the Delaware constitution and reported judicial decisions interpreting the foregoing). We hereby consent to the reference to us under the heading “Validity of the Common Units” in the prospectus forming a part of the Registration Statement and to the filing of this opinion as an exhibit to the Registration Statement. In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the SEC issued thereunder.
Very truly yours,
/s/ Andrews Kurth LLP

     RE:     REGISTRATION STATEMENT ON FORM S-1
Ladies and Gentlemen:
     We have acted as special counsel for Duncan Energy Partners L.P. (the “Partnership”), a Delaware limited partnership, with respect to certain legal matters in connection with the offer and sale (the “Offering”) of common units representing limited partner interests in the Partnership (“Common Units”). We have also participated in the preparation of a Registration Statement on Form S-1 and the amendments thereto (No. 333-138371) (such registration statement, as amended, the “Registration Statement”) to which this opinion is an exhibit. In connection therewith, we have participated in the preparation of the discussion set forth under the caption “Material Tax Consequences” (the “Discussion”) in the Registration Statement.
     The Discussion, subject to the qualifications and assumptions stated in the Discussion and the limitations and qualifications set forth herein, constitutes our opinion as to the material United States federal income tax consequences for purchasers of the Common Units pursuant to the Offering.
     This opinion letter is limited to the matters set forth herein, and no opinions are intended to be implied or may be inferred beyond those expressly stated herein. We assume no obligation to update or supplement this opinion or any matter related to this opinion to reflect any change of fact, circumstances, or law after the effective date of the Registration Statement. In addition, our opinion is based on the assumption that the matter will be properly presented to the applicable court.

     Furthermore, our opinion is not binding on the Internal Revenue Service or a court. In addition, we must note that our opinion represents merely our best legal judgment on the matters presented and that others may disagree with our conclusion. There can be no assurance that the Internal Revenue Service will not take a contrary position or that a court would agree with our opinion if litigated.
     We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to our firm and this opinion contained in the Discussion. In giving this consent, we do not admit that we are “experts” under the Securities Act of 1933, as amended, or under the rules and regulations of the Securities and Exchange Commission relating thereto, with respect to any part of the Registration Statement.
Very truly yours,
/s/ Andrews Kurth LLP
