5. Agreements. Each of the Partnership and the General Partner agrees with the several Underwriters that: (a) The Partnership will use its best efforts to cause any amendment to the Registration Statement to become effective. Prior to the termination of the offering of the Securities, the Partnership will not file any amendment of the Registration Statement or supplement to the Prospectus or any Rule 462(b) Registration Statement unless the Partnership has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. Subject to the foregoing sentence, if filing of the Prospectus is required under Rule 424(b), the Partnership will cause the Prospectus, properly completed, and any supplement thereto to be filed with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Underwriters of such timely filing. The Partnership will promptly advise the Underwriters (1) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (2) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (3) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Prospectus or for any additional information, (4) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose and (5) of the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Partnership will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof. (b) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act, any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, the Partnership promptly will (1) notify the Underwriters of such event, (2) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement which will correct such statement or omission or effect such compliance and (3) supply any supplemented Prospectus to you in such quantities as you may reasonably request. (c) The Partnership will furnish to the Underwriters and counsel for the Underwriters, without charge, a copy of the Registration Statement (including exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act, as many copies of the Prospectus and any supplement thereto as the Underwriters may reasonably request. The Partnership will pay the expenses of printing or other production of all documents relating to the offering. 12

(d) The Partnership will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Underwriters may designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of the National Association of Securities Dealers, Inc. in connection with its review of the offering; provided that in no event shall the Partnership be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject. (e) The Heritage Parties will not, during the 90 days after the date of this Underwriting Agreement, without the prior written consent of the Underwriters, directly or indirectly, offer for sale, contract to sell, distribute, grant any option, right or warrant to purchase, pledge, hypothecate or otherwise dispose of any Common Units or any securities convertible into, or exercisable, or exchangeable for, Common Units; or publicly announce an intention to effect any such transaction, provided, however, that the Heritage Parties may contribute Common Units to the Partnership and may issue and sell Common Units (i) to the Underwriters pursuant to this Underwriting Agreement, (ii) pursuant to the Second Amended and Restated Restricted Unit Plan dated as of February 4, 2002, (iii) to the General Partner or its affiliates in connection with any acquisition by the Heritage Parties of assets or similar prior acquisitions, (iv) in a transaction not involving a public offering to purchasers who enter into an agreement with the Underwriters in the form set forth in Exhibit A, (v) in one or more transactions from and after 30 days from the date of this Underwriting Agreement, utilizing the Partnership's Form S-4 Registration Statement for the contribution of assets to the Partnership or its affiliates in exchange for Common Units, but not to exceed an aggregate of 50,000 Common Units under this exception (v), and (vi) as a capital contribution required on account of the issuance and sale of Common Units to the Underwriters pursuant to this Underwriting Agreement. (f) The Heritage Parties will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Securities. 6.

(f) The Partnership shall have requested and caused Grant Thornton LLP to have furnished to the Underwriters, at the Execution Time and at the Closing Date, letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Underwriters, confirming that they are independent public accountants within the meaning of the Act and the respective applicable rules and regulations adopted by the Commission thereunder and that they have performed a review of the unaudited interim financial information of the Partnership for the six-month period ended February 28, 2003, and as at February 28, 2003 in accordance with Statement on Auditing Standards No. 71, and stating in effect that: (i) in their opinion the audited consolidated or combined financial statements, as applicable, incorporated by reference in the Registration Statement and the Prospectus and reported on by them comply as to form in all material respects with the applicable accounting requirements of the Act and the Exchange Act and the related rules and regulations adopted by the Commission; 23

(ii) on the basis of a reading of the latest unaudited consolidated financial statements made available by the Partnership and its subsidiaries; their limited review, in accordance with standards established under Statement on Auditing Standards No. 71, of the unaudited interim financial information for the six-month period ended February 28, 2003, and as at February 28, 2003, incorporated by reference in the Registration Statement and the Prospectus; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the minutes of the meetings of the directors, Audit Committee or other governing committee of the Partnership, the General Partner or U.S. Propane, L.L.C.; and inquiries of certain officials of the Partnership who have responsibility for financial and accounting matters of the Partnership as to transactions and events subsequent to August 31, 2002, nothing came to their attention which caused them to believe that: (1) any unaudited consolidated financial statements incorporated by reference in the Registration Statement and the Prospectus do not comply as to form in all material respects with applicable accounting requirements of the Act and with the related rules and regulations adopted by the Commission with respect to financial statements incorporated by reference in quarterly reports on Form 10-Q under the Exchange Act; and said unaudited consolidated financial statements are not in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited consolidated financial statements incorporated by reference in the Registration Statement and the Prospectus; (2) with respect to the period subsequent to February 28, 2003, there were any changes, at a specified date not more than five days prior to the date of the letter, in the Common Units, increase in long-term debt or any decreases in consolidated net current assets or partners' capital as compared with the amounts shown on the February 28, 2003, unaudited condensed consolidated balance sheet incorporated by reference in the Registration Statement and the Prospectus, or for the period from March 1, 2003 to such specified date there were any decreases, as compared with the corresponding period in the preceding year, in consolidated total revenues or in the total or per-unit amounts of net income, except in all instances for changes, increases or decreases set forth in such letter, in which case the letter shall be accompanied by an explanation by the Partnership as to the significance thereof unless said explanation is not deemed necessary by the Underwriters; or (3) the information incorporated by reference in the Registration Statement and Prospectus in response to Regulation S-K, Item 301 (Selected Historical Financial and Operating Data) is not in 24

conformity with the applicable disclosure requirements of Regulation S-K; and (iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Partnership and its subsidiaries) set forth in the Registration Statement and the Prospectus, including the information included or incorporated by reference in Items 1, 2, 6, 7 and 11 of the Partnership's Annual Report on Form 10-K, incorporated by reference in the Registration Statement and the Prospectus, the information included in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included or incorporated by reference in the Partnership's Quarterly Reports on Form 10-Q, incorporated by reference in the Registration Statement and the Prospectus, and the unaudited pro forma combined financial statements included in the Partnership's Current Report on Form 8-K/A dated January 2, 2003, as amended on March 18, 2003, incorporated by reference is the Registration Statement and the Prospectus, agrees with the accounting records of the Partnership and its subsidiaries, excluding any questions of legal interpretation. (iv) on the basis of a reading of the unaudited pro forma combined balance sheet as of November 30, 2002, and the unaudited pro forma combined statements of operations for the year ended August 31, 2002 and the three months ended November 30, 2002, included in the Partnership's Form 8-K/A dated January 2, 2003, as amended on March 18, 2003, incorporated by reference in the Registration Statement and the Prospectus; an inquiry of certain officials of the Partnership who have responsibility for financial accounting matters about the basis for their determination of the pro forma adjustments, and whether the unaudited pro forma combined financial statements comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X; and proving the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in the unaudited pro forma combined financial statements, nothing came to their attention that caused them to believe that the unaudited pro forma combined financial statements incorporated by reference in the Registration Statement and Prospectus do not comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X and that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of those statements. References to the Prospectus in this paragraph (f) include any supplement thereto at the date of the letter. (g) The Partnership shall have requested and caused Grant Thornton LLP to have furnished to the Underwriters, at the Execution Time, a letter dated as of the Execution Time, in form and substance satisfactory to the Underwriters, confirming that they have performed agreed-upon procedures in accordance with the attestation standards 25

established by the American Institute of Certified Public Accountants, and stating in effect that: (i) they have compared the indicated quantity, amount or percentage of items identified by the Partnership and the Underwriters in the Partnership's 10-K for the year ended August 31, 2002, to the corresponding quantity, amount or percentage in the audited consolidated financial statements or notes thereto included in the Partnership's reports on Form 10-K for 1997 through 2000 (such audits performed by Arthur Andersen LLP, the Partnership's former independent public accountants), and found such quantities, amounts or percentages to be in agreement, after considering rounding; and (ii) they have recomputed the indicated quantity, amount or percentage of items identified by the Partnership and the Underwriters in the Partnership's 10-K for the year ended August 31, 2002, using amounts included in or derived from the audited consolidated financial statements or notes thereto included in the Partnership's annual reports on Form 10-K for 1997 through 2000, and found such quantities, amounts or percentages to be in agreement, after considering rounding. (h) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Prospectus (exclusive of any supplement thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraphs (f) or (g) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Partnership and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Prospectus (exclusive of any supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Underwriters, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Registration Statement (exclusive of any amendment thereof) and the Prospectus (exclusive of any supplement thereto). (i) Prior to the Closing Date, the Heritage Parties shall have furnished to the Underwriters such further information, certificates and documents as the Underwriters may reasonably request. (j) The Securities shall have been listed and admitted and authorized for trading on the New York Stock Exchange, and satisfactory evidence of such actions shall have been provided to the Underwriters. (k) At the Execution Time, the General Partner shall have furnished to the Underwriters a letter substantially in the form of Exhibit A hereto from each executive officer and director of the General Partner and U.S. Propane, L.L.C. addressed to the Underwriters. 26

(l) There shall not have occurred any of the following: (i) a suspension or material limitation in trading securities generally on the New York Stock Exchange or the establishing on such market by the Commission or by such market of minimum or maximum prices which are not in force and effect on the date hereof; (ii) a suspension or material limitation in trading in the Partnership's securities on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either federal or Missouri authorities; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, which in your judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities in the manner contemplated in the Prospectus; or (v) any calamity or crisis, change in national, international or world affairs, act of God, change in the international or domestic markets, or change in the existing financial, political or economic conditions in the United States or elsewhere, the effect of which on the financial markets of the United States is such as to make it in your judgment impracticable or inadvisable to proceed with the public offering or the delivery of the Securities in the manner contemplated in the Prospectus. If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Underwriters and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Underwriters. Notice of such cancellation shall be given to the Partnership in writing or by telephone or facsimile confirmed in writing. The documents required to be delivered by this Section 6 shall be delivered at the office of Baker Botts L.L.P., counsel for the Partnership, at 910 Louisiana Street, Houston, Texas 77002, on the Closing Date. 7. Reimbursement of the Underwriters' Expenses. If the sale of the Securities provided for herein is not consummated because of any termination pursuant to Section 9 hereof (other than a termination thereunder as a result of the occurrence of an event described in 6(l)(i), (iii), (iv) or (v)), or because of any refusal, inability or failure on the part of the Heritage Parties to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Underwriters, the Partnership will reimburse the Underwriters on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities. 27

8. Indemnification and Contribution. (a) The Heritage Parties, jointly and severally, will indemnify and hold harmless the Underwriters, the directors, officers, employees and agents of the Underwriters and each person who controls the Underwriters, within the meaning of either the Act or the Exchange Act, from and against any losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or claims in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, and will reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Heritage Parties will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Heritage Parties by or on behalf of the Underwriters specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Heritage Parties may otherwise have. (b) The Underwriters will indemnify and hold harmless the Heritage Parties, each person who signed the Registration Statement and each person who controls a Heritage Party, including officers and directors thereof, within the meaning of either the Act or the Exchange Act, from and against any losses, claims, damages or liabilities, joint or several, to which the Heritage Parties may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or claims in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, and will reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; in each such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with 28

written information furnished to the Heritage Parties by or on behalf of the Underwriters specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Underwriters may otherwise have. (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would, based on advice of counsel to the indemnified party, present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded, based on advice from its counsel, that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Heritage Parties jointly and severally and the Underwriters agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively 29

"Losses") to which the Heritage Parties and the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Heritage Parties on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall the Underwriters (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Heritage Parties jointly and severally and the Underwriters shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Heritage Parties on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Heritage Parties shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by Heritage Parties on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Heritage Parties and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls the Underwriters within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of the Underwriters shall have the same rights to contribution as the Underwriters, and each person who controls a Heritage Party within the meaning of either the Act or the Exchange Act, each person who shall have signed the Registration Statement and each director of the General Partner shall have the same rights to contribution as the General Partner, subject in each case to the applicable terms and conditions of this paragraph (d). 9. Termination. (a) This Agreement may be terminated by you at any time at or prior to the Closing Date in accordance with the second to last paragraph of Section 6. Any such termination shall be without liability of any party to any other party except as provided in Sections 8 and 10 hereof. (b) This Agreement also may be terminated by you, by notice to the Partnership, as to any obligation of the Underwriters to purchase the Option Units, if any condition specified in the second to last paragraph of Section 6 hereof shall not have been satisfied at or prior to the Option Closing Date. 30

If you terminate this Agreement as provided in Sections 9(a) or 9(b), you shall notify the Partnership by telephone or telegram, confirmed by letter. 10. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Heritage Parties or their officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters or the Heritage Parties or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement. 11. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Underwriters, will be mailed, delivered or telefaxed to the c/o A.G. Edwards & Sons, Inc. General Counsel (fax no.: (314) 955-3000) and confirmed to the General Counsel, A.G. Edwards & Sons, Inc., at One North Jefferson, St. Louis, Missouri 63103, Attention: General Counsel; or, if sent to the Partnership, will be mailed, delivered or telefaxed to (918) 493-7290 and confirmed to it at (918) 492-7272, attention of the President. 12. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder. 13. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of Missouri, without giving effect to the choice of law or conflict of laws principles thereof. 14. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement. 15. Headings. The section headings used herein are for convenience only and shall not affect the construction hereof. 16. Definitions.

[LETTERHEAD OF BAKER BOTTS L.L.P.] May 13, 2003 EXHIBIT 5.1 Heritage Propane Partners, L.P. 8801 South Yale Avenue, Suite 310 Tulsa, Oklahoma 74137 Gentlemen: We have acted as special counsel to Heritage Propane Partners, L.P., a Delaware limited partnership (the "Partnership"), in connection with the Partnership's offer and sale of up to an aggregate of 1,610,000 common units representing limited partner interests in the Partnership (the "Common Units") pursuant to the Partnership's Registration Statement on Form S-3 (Registration No. 333-86057) (the "Registration Statement"). In our capacity as your counsel in the connection referred to above, we have examined the Partnership's Certificate of Limited Partnership and Amended and Restated Agreement of Limited Partnership (the "Partnership"), each as amended to date, the originals, or copies certified or otherwise identified, of certificates of public officials and of representatives of the Partnership, statutes and other instruments and documents as a basis for the opinions hereafter expressed. Based upon and subject to the foregoing, we are of the opinion that: The Common Units have been duly and validly authorized and, when issued and delivered against payment therefor in accordance with the terms of the underwriting agreement relating thereto will be, fully paid (to the extent required in the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by certain provisions of the Delaware Revised Uniform Limited Partnership Act). We hereby consent to the filing of this opinion of counsel as an exhibit to a Current Report on Form 8-K dated May 13, 2002 of the Partnership, the incorporation by reference of this opinion by the Registration Statement and the reference to our Firm under the heading "Legal Matters" in the prospectus supplement forming a part of the Registration Statement. In giving this consent, we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.

[LETTERHEAD OF BAKER BOTTS L.L.P.] May 13, 2003 EXHIBIT 8.1 Heritage Propane Partners, L.P. 8801 South Yale Avenue, Suite 310 Tulsa, Oklahoma 74137 Re: Tax Opinion Gentlemen: We have acted as special counsel in connection with the Registration Statement on Form S-3 (Registration No. 333-86057) (the "Registration Statement") and the Prospectus Supplement dated May 13, 2003 (the "Supplement") to the Prospectus dated September 13, 1999 of Heritage Propane Partners, L.P., a Delaware limited partnership (the "Partnership"), relating to the registration of the offering and sale (the "Offering") of up to 1,610,000 common units (including common units that may be issued pursuant to the over-allotment option described in the Supplement) ("Common Units") to be issued and sold by the Partnership pursuant to Rule 415 under the Securities Act of 1933, as amended (the "Act"). In connection therewith, we have participated in the preparation of the discussions with respect to the Common Units set forth under the caption "Tax Considerations" in the Registration Statement and in the Supplement (collectively, the "Discussion").
