Section 2. Sale and Delivery to Underwriters; Closing.

(a) Firm Units. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Partnership agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Partnership, at the price per Unit set forth in Schedule A, that number of Firm Units set forth in Schedule A opposite the name of such Underwriter, plus any additional number of Firm Units which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof, subject, in each case, to such adjustments among the Underwriters as the Representatives in their absolute discretion shall make to eliminate any sales or purchases of fractional Units.

(b) Option Units. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Partnership hereby grants an option to the Underwriters to purchase, severally and not jointly, up to an additional 576,922 Common Units, at the price per unit set forth in Schedule A. The option hereby granted may be exercised for 30 days after the date hereof and may be exercised in whole or in part at any time from time to time upon notice by the Representatives to the Partnership setting forth the number of Option Units as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Units. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representatives, but shall not be sooner than three full business days nor later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time. If the option is exercised as to all or any portion of the Option Units, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Units then being purchased which the number of Firm Units set forth in Schedule A opposite the name of such Underwriter bears to the total number of Firm Units, subject, in each case, to such adjustments as the Representatives in their absolute discretion shall make to eliminate any sales or purchases of fractional Units.

The purchase price payable by the several Underwriters for both the Firm Units and any Option Units shall be $37.44 per Unit; provided, that the Firm Units to be sold to the Affiliated Purchasers, representing up to 7,692 Units in the aggregate (the “Insider Units”), shall be purchased by the Underwriters from the Partnership at a purchase price of $39.00 per Unit.

(c) Payment. Payment of the purchase price for, and delivery of, the Firm Units shall be made at the offices of Bradley Arant Boult Cummings LLP at ONE 22 ONE, 1221 Broadway, Suite 2400, Nashville, Tennessee 37203, or at such other place as shall be agreed upon by the Representatives and the Partnership, at 10:00 A.M. (New York City time) on the second (third, if the pricing occurs after 4:30 P.M. (New York City time) on any given day) business day after the

date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Partnership (such time and date of payment and delivery being herein called “Closing Time”).

In addition, in the event that any or all of the Option Units are purchased by the Underwriters, payment of the purchase price for, and delivery of such Option Units shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representatives and the Partnership, on each Date of Delivery as specified in the notice from the Representatives to the Partnership.

Payment shall be made to the Partnership by wire transfer of immediately available funds to a bank account designated by the Partnership against delivery to the Representatives for the respective accounts of the Underwriters for the Units to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Firm Units and the Option Units, if any, which it has agreed to purchase. The Representatives, individually and not as representatives of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Firm Units or the Option Units, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder. Delivery of the Firm Units and the Option Units shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct.

Section 3. Covenants of the Partnership. Each of the Partnership Parties, jointly and severally, covenant with each Underwriter as follows:

(a) Compliance with Securities Regulations and Commission Requests. The Partnership, subject to Section 3(b), will comply with the requirements of Rule 430B, and will notify the Representatives promptly, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective or any amendment or supplement to the Prospectus shall have been filed, (ii) of the receipt of any comments on the Registration Statement from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment or of any order preventing or suspending the use of any preliminary prospectus or the Prospectus, or of the suspension of the qualification of the Units for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(d) or 8(e) of the Securities Act concerning the Registration Statement and (v) if the Partnership becomes the subject of a proceeding under Section 8A of the Securities Act in connection with the offering of the Units. The Partnership will effect all filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Partnership will make every reasonable effort to prevent the issuance of any stop order, prevention or suspension and, if any such order is issued, to obtain the lifting thereof as soon as practicable.

(b) Continued Compliance with Securities Laws. The Partnership will comply with the Securities Act and the Securities Act Regulations so as to permit the completion of the distribution of the Units as contemplated in this Agreement and in the Registration Statement, the General Disclosure Package and the Prospectus. If at any time when a prospectus relating to the Units is (or, but for the exception afforded by Rule 172 of the Securities Act Regulations (“Rule 172”), would be) required by the Securities Act to be delivered in connection with sales of the Units, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Partnership, to (i) amend the Registration Statement in order that the Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, (ii) amend or supplement the General Disclosure Package or the Prospectus in order that the General Disclosure Package or the Prospectus, as the case may be, will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is delivered to a purchaser, not misleading or (iii) amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus, as the case may be, in order to comply with the requirements of the Securities Act or the Securities Act Regulations, the Partnership will promptly (A) give the Representatives notice of such event, (B) prepare any amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement, the General Disclosure Package or the Prospectus comply with such requirements and, at least one day prior to any proposed filing or use, furnish the Representatives with copies of any such amendment or supplement and (C) file with the Commission any such amendment or supplement, provided that the Partnership shall not file or use any such amendment or supplement to which the Representatives or counsel for the Underwriters shall reasonably object. The Partnership will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. The Partnership has given the Representatives notice of any filings made pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or the rules and regulations under the Exchange Act (the “Exchange Act Regulations”) within 48 hours prior to the Applicable Time; the Partnership will give the Representatives notice of its intention to make any such filing from the Applicable Time to the Closing Time and will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object.

(c) Delivery of Registration Statements. The Partnership has furnished or will deliver, upon request, to the Representatives and counsel for the Underwriters, without charge, signed copies of the Registration Statement as originally filed and each amendment thereto (including exhibits filed therewith) and signed copies of all consents and certificates of experts, and will also deliver to the Representatives, upon request, without charge, a conformed copy of the Registration Statement as originally filed and each amendment thereto (without exhibits) for each of the Underwriters. Such copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(d) Delivery of Prospectuses. The Partnership has delivered to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter reasonably requested, and the Partnership hereby consents to the use of such copies for purposes permitted by the Securities Act. The Partnership will furnish to each Underwriter, without charge, during the period when a prospectus relating to the Units is (or, but for the exception afforded by Rule 172, would be) required to be delivered under the Securities Act, such number of copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(e) Blue Sky Qualifications. The Partnership will use its reasonable best efforts, in cooperation with the Underwriters, to qualify the Units for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may designate and to maintain such qualifications in effect so long as required to complete the distribution of the Units; provided, however, that the Partnership shall not be obligated to file any general consent to service of process or to qualify to do business or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(f) Rule 158. The Partnership will timely file such reports pursuant to the Exchange Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the Securities Act.

(h) Listing. The Partnership will use its reasonable best efforts to effect and maintain the listing of the Units on the NYSE.

(i) Restriction on Sale of Units. During a period of 60 days from the date of the Prospectus (the “Restricted Period”), the Partnership will not, without the prior written consent of the Representatives, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Partnership Parties) any Common Units or any securities convertible into or exercisable or exchangeable for Common Units or file any registration statement under the Securities Act with respect to any of the foregoing; provided that the Partnership may enter into agreements during the Restricted Period in connection with any merger, acquisition, joint venture or the acquisition or license of the business, property, technology or other assets of another individual or entity that include the offer, sale, contract to sell or other transfer or disposal of Common Units or any securities convertible into or exercisable or exchangeable for Common Units that is consummated after the Restricted Period, or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Units, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of

Common Units or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (A) the Units to be sold hereunder, (B) any Common Units issued by the Partnership upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the Registration Statement, the General Disclosure Package and the Prospectus, (C) any Common Units issued or options to purchase Common Units granted pursuant to any employee benefit plan of the Partnership or the General Partner referred to in the Registration Statement, the General Disclosure Package and the Prospectus or the filing of a registration statement on Form S-8 in respect thereof, (D) any Common Units issued pursuant to any non-employee director stock plan or dividend reinvestment plan referred to in the Registration Statement, the General Disclosure Package and the Prospectus or the filing of a registration statement in respect thereof or (E) the pledge of securities as collateral pursuant to the agreements set forth on Schedule D.

(j) Reporting Requirements. The Partnership, during the period when a Prospectus relating to the Units is (or, but for the exception afforded by Rule 172, would be) required to be delivered under the Securities Act, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and Exchange Act Regulations. Additionally, the Partnership shall report the use of proceeds from the issuance of the Units as may be required under Rule 463 under the Securities Act.

(k) Issuer Free Writing Prospectuses. The Partnership agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Partnership that unless it has or shall have obtained, as the case may be, the prior written consent of the General Partner, it has not made and will not make any offer relating to the Units that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus,” or a portion thereof, required to be filed by the Partnership with the Commission or retained by the Partnership under Rule 433; provided that consent will be deemed to have been given with respect to the Issuer Free Writing Prospectuses listed on Schedule B-2 hereto and any “road show that is a written communication” within the meaning of Rule 433(d)(8)(i) that has been reviewed by the Representatives and the Partnership. The Partnership represents that it has treated or agrees that it will treat each such free writing prospectus consented to, or deemed consented to, by the Representatives as an “issuer free writing prospectus,” as defined in Rule 433, and that it has complied and will comply with the applicable requirements of Rule 433 with respect thereto, including timely filing with the Commission where required, legending and record keeping. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, the most recent preliminary prospectus or the Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that time, not misleading, the Partnership will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(l) Written Testing-the-Waters Communications. If at any time following the distribution of any Written Testing-the-Waters Communication there occurred or occurs an event or development as a result of which such Written Testing-the-Waters Communication included or

would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that time, not misleading, the Partnership will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Written Testing-the-Waters Communication to eliminate or correct such untrue statement or omission.

Section 4. Payment of Expenses.

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the

In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Partnership Parties. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

Section 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (a) in such proportion as is appropriate to reflect the relative benefits received by the Partnership Parties, on the one hand, and the Underwriters, on the other hand, from the offering of the Units pursuant to this Agreement or (b) if the allocation provided by clause (a) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (a) above but also the relative fault of the Partnership Parties, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Partnership Parties, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Units pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Units pursuant to this Agreement (before deducting expenses) received by the Partnership, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus.

The relative fault of the Partnership Parties, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Partnership Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Units underwritten by it and distributed to the public.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the General Partner, each officer of the General Partner who signed the Registration Statement, and each person, if any, who controls the Partnership Parties within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Partnership Parties. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Firm Units set forth opposite their respective names in Schedule A hereto and not joint.

Section 8. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Partnership Parties submitted pursuant hereto, shall remain operative and in full force and effect regardless of (a) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors or any person controlling the Partnership Parties and (b) delivery of and payment for the Units.

Section 9. Termination of Agreement.

(a) Termination. The Representatives may terminate this Agreement, by notice to the Partnership, at any time at or prior to the Closing Time (i) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Units, (ii) if trading in the Units of the Partnership has been suspended or materially limited by the Commission or the NYSE, (iii) if trading generally on the NYSE or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (v) if a banking moratorium has been declared by either Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 6, 7, 14 and 15 shall survive such termination and remain in full force and effect.

Section 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time or a Date of Delivery to purchase the Units which it or they are obligated to purchase under this Agreement (the “Defaulted Units”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Units in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a) if the number of Defaulted Units does not exceed 10% of the number of Units to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the number of Defaulted Units exceeds 10% of the number of Units to be purchased on such date, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any of the Defaulted Units and if such non-defaulting Underwriters do not elect to purchase all the Defaulted Units, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase, and the Partnership to sell, the Option Units to be purchased and sold on such Date of Delivery, shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Partnership to sell the relevant Option Units, as the case may be, either the (i) Representatives or (ii) Partnership shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

Section 11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Partnership, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

Section 13. No Advisory or Fiduciary Relationship. Each of the Partnership Entities acknowledges and agrees that (a) the purchase and sale of the Units pursuant to this Agreement, including the determination of any related discounts and commissions, is an arm’s-length commercial transaction between the Partnership Parties, on the one hand, and the several Underwriters, on the other hand, (b) in connection with the offering of the Units and the process leading thereto, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Partnership Parties, any of their subsidiaries or their respective stockholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an

advisory or fiduciary responsibility in favor of the Partnership Parties with respect to the offering of the Units or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Partnership Parties or any of their subsidiaries on other matters) and no Underwriter has any obligation to the Partnership Parties with respect to the offering of the Units except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Partnership Parties and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Units and the Partnership Parties have consulted their own respective legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

Section 14. Parties. This Agreement shall inure to the benefit of and be binding upon the Underwriters and the Partnership Parties and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Partnership Parties and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.

Ladies and Gentlemen:

The undersigned understands that BofA Securities, Inc. (“BofA”), Barclays Capital Inc. (“Barclays”), RBC Capital Markets, LLC (“RBC”) (together with BofA, RBC and Barclays, the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Delek Logistics Partners, LP, a Delaware limited partnership (the “Partnership”), and Delek Logistics GP, LLC, a Delaware limited liability company and the general partner of the Partnership, providing for the public offering (the “Public Offering”) by the Representatives of 3,846,153 common units representing limited partner interests in the Partnership (the “Common Units”).

To induce the Representatives to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives, it will not, and will not publicly disclose an intention to, during the period commencing on the date hereof and ending 60 days after the date of the final prospectus (the “Restricted Period”) relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Units beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Units or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to the Common Units being sold or transferred pursuant to the transactions contemplated by the Underwriting Agreement, (b) transactions relating to Common Units or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in

B-1

connection with subsequent sales of Common Units or other securities acquired in such open market transactions, (c) transfers of Common Units or any security convertible into Common Units as a bona fide gift or for bona fide estate planning purposes, or by will, other testamentary document or intestate succession to the legal representative, heir, beneficiary or a member of the immediate family of the undersigned upon the death of the undersigned, or by operation of law pursuant to a domestic order or negotiated divorce settlement; or (d) distributions of Common Units or any security convertible into Common Units to limited partners, stockholders, members, general partners, managers, directors, officers or employees or trust beneficiaries of the undersigned or the undersigned’s affiliates; provided that in the case of any transfer or distribution pursuant to clause (c) or (d), each donee, distributee or transferee, as applicable, shall sign and deliver a lock up agreement substantially in the form of this agreement, (e) facilitating the establishment of a trading plan on behalf of a unitholder, officer or director of the Partnership pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Common Units, provided that (i) such plan does not provide for the transfer of Common Units during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Partnership regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Units may be made under such plan during the Restricted Period; (f) sales of Common Units made pursuant to and in accordance with a trading plan pursuant to Rule 10b5-1 under the Exchange Act existing on the date hereof, provided that any public filing or public announcement under Section 16(a) of the Exchange Act required during the Restricted Period made in connection with sales under this clause (f) shall clearly indicate in the footnotes thereto or comments section that such sales were made pursuant to a Rule 10b5-1 trading plan under the Exchange Act; or (g) any transfers made by the undersigned to the Partnership to satisfy tax withholding obligations pursuant to the Partnership’s equity incentive plans or arrangements disclosed in the Prospectus; provided that any public filing or public announcement under Section 16(a) of the Exchange Act required during the Restricted Period made in connection with sales under this clause (g) shall clearly indicate in the footnotes thereto or comments section that such sales were made to satisfy tax withholding obligations pursuant to the Partnership’s equity incentive plans or arrangements disclosed in the Prospectus. In addition, the undersigned agrees that, without the prior written consent of the Representatives, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any Common Units or any security convertible into or exercisable or exchangeable for Common Units. The undersigned also agrees and consents to the entry of stop transfer instructions with the Partnership’s transfer agent and registrar against the transfer of the undersigned’s Common Units except in compliance with the foregoing restrictions.

The undersigned understands that the Partnership and the Underwriter are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

The undersigned acknowledges and agrees that the Underwriter has not provided any recommendation or investment advice nor have the Underwriter solicited any action from the undersigned with respect to the Public Offering of the Units and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate. The undersigned further acknowledges and agrees that, although the Underwriter may

provide certain Regulation Best Interest and Form CRS disclosures or other related documentation to you in connection with the Public Offering, the Underwriter is not making a recommendation to you to participate in the Public Offering or sell any Units at the price determined in the Public Offering, and nothing set forth in such disclosures or documentation is intended to suggest that the Underwriter is making such a recommendation.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Partnership and the Underwriter. The undersigned understands that if (i) the Underwriting Agreement (other than provisions thereof which survive termination) is terminated prior to the Closing Time (as defined in the Underwriting Agreement), (ii) the Partnership notifies the Representatives in writing, prior to the execution of the Underwriting Agreement, that the Partnership does not intend to proceed with the Public Offering or (iii) the registration statement filed with the Securities and Exchange Commission in connection with the Public Offering is withdrawn, the undersigned shall be released from all obligations under this agreement.

This agreement shall be governed by and construed in accordance with the laws of the State of New York.

Very truly yours,
