(mm) Environmental Laws. Each Dynagas Entity (i) is in compliance with any and all applicable foreign, federal, state and local laws and regulations relating to pollution or the protection of the environment or imposing liability or standards of conduct concerning the use, handling, storage or management of any Hazardous Materials (as defined herein) (“Environmental Laws”), (ii) have received all permits required of them under applicable Environmental Laws to conduct their respective businesses as presently conducted (“Environmental Permits”) except for any such Environmental Permits that are the responsibility of the charter parties under the Covered Agreements and that the Partnership Parties reasonably expect such charter parties to obtain, (iii) are in compliance with all terms and conditions of any such permits and (iv) do not have any liability in connection with any known or threatened release into the environment of any Hazardous Material, except in the case of each of clauses (i), (ii), (iii) and (iv) as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The term “Hazardous Material” means (A) any “hazardous substance” as defined in the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, (B) any “hazardous waste” as defined in the Resource Conservation and Recovery Act, as amended, (C) any petroleum or petroleum product, (D) any polychlorinated biphenyl and (E) any hazardous, toxic chemical, material, waste or substance regulated under or within the meaning of any applicable Environmental

Law. In the ordinary course of business, the Partnership Entities periodically review the effect of Environmental Laws on their business, operations and properties, in the course of which they identify and evaluate costs and liabilities that they believe are reasonably likely to be incurred pursuant to such Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review, the Partnership Entities have reasonably concluded that such associated costs and liabilities relating to the Vessels would not, individually or in the aggregate, have a Material Adverse Effect. To the knowledge of the Partnership Parties, the parties to the Covered Agreements possess, or reasonably expect to possess in the ordinary course as necessary, the Environmental Permits that are the responsibility of the charter parties to obtain pursuant to the terms of the Covered Agreements.

(nn) Tax Returns. The Partnership Entities and their subsidiaries have filed all federal, state, local and non-U.S. tax returns that are required to be filed by them or have requested extensions thereof (except in any case in which the failure so to file would not have a Material Adverse Effect); and, except as set forth in the General Disclosure Package, Partnership Entities and their subsidiaries have paid all taxes (including any assessments, fines or penalties) required to be paid by them, except for any such taxes, assessments, fines or penalties currently being contested in good faith or as would not, individually or in the aggregate, have a Material Adverse Effect.

The Partnership Entities are insured by insurers (which term shall include P&I clubs) against such losses and risks and in such amounts as are prudent and customary for the businesses in which they are engaged, and the Partnership Entities and their subsidiaries are in compliance with the terms of such policies and instruments in all material respects. Except as disclosed in the General Disclosure Package and the Final Prospectus, there are no claims by the Partnership Entities or any of their subsidiaries under any such policy or instrument as to which any insurance company is denying liability or defending under a reservation of rights clause which would, individually or in the aggregate, have a Material Adverse Effect.

Except as set forth in the General Disclosure Package, the Partnership, its subsidiaries and the board of directors of the General Partner are in compliance with applicable Xxxxxxxx-Xxxxx and Exchange Rules. To the extent required under the Securities Laws, the Partnership maintains a system of internal controls, including, but not limited to, disclosure controls and procedures, internal controls over accounting matters and financial reporting, an internal audit function and legal and regulatory compliance controls (collectively, “Internal Controls”) that comply with the Securities Laws and are sufficient

to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with U.S. General Accepted Accounting Principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. To the extent required under the Securities Laws, the Internal Controls are overseen by the Audit Committee (the “Audit Committee”) of the Board in accordance with Exchange Rules. The Partnership has not publicly disclosed or reported to the Audit Committee or the Board, and within the next 135 days the Partnership does not reasonably expect to publicly disclose or report to the Audit Committee or the Board, a significant deficiency, material weakness, change in any required Internal Controls or fraud involving management or other employees who have a significant role in any required Internal Controls (each, an “Internal Control Event”), any violation of, or failure to comply with, the Securities Laws, or any matter which, if determined adversely, would have a Material Adverse Effect.

(tt) Absence of Accounting Issues. A member of the Audit Committee has confirmed to the Chief Executive Officer or the Chief Financial Officer or General Counsel that, except as set forth in the General Disclosure Package, the Audit Committee is not reviewing or investigating, and neither the Partnership’s independent auditors nor its internal auditors have recommended that the Audit Committee review or investigate, (i) adding to, deleting, changing the application of, or changing the Partnership’s disclosure with respect to, any of the Partnership’s material accounting policies; (ii) any matter which could result in a restatement of the Partnership’s financial statements for any annual or interim period during the current or prior two fiscal years; or (iii) any Internal Control Event.

(uu) Litigation. Except as disclosed in the General Disclosure Package and the Final Prospectus, there are no pending actions, suits or proceedings (including any inquiries or investigations by any court or governmental agency or body, domestic or foreign) against or affecting the Partnership Parties, any of their subsidiaries or any of their respective properties that, if determined adversely to the Partnership Parties or any of their subsidiaries, would individually or in the aggregate have a Material Adverse Effect, or would materially and adversely affect the ability of the Partnership Parties to perform their obligations under this Agreement, or which are otherwise material in the context of the sale of the Offered Units; and no such actions, suits or proceedings (including any inquiries or investigations by any court or governmental agency or body, domestic or foreign) are threatened or, to the Partnership Parties’ knowledge, contemplated.

(vv) Inapplicability of ERISA. None of the Partnership Parties has incurred or is reasonably likely to incur any material liability under Title IV of the Employee Retirement Income Security Act of 1974, as amended.

(ww) Financial Statements. The financial statements included in each Registration Statement and the General Disclosure Package present fairly the financial position of the Partnership and its consolidated subsidiaries as of the dates shown and their results of operations and cash flows for the periods shown, and such financial statements have been prepared in conformity with the generally accepted accounting principles in the United States applied on a consistent basis and the schedules included in each Registration Statement present fairly the information required to be stated therein.

(xx) No Material Adverse Change in Business. Except as disclosed in the General Disclosure Package and the Final Prospectus (excluding, however, any amendments or supplements thereto dated after the date hereof), since the end of the period covered by the latest audited financial statements included in the General Disclosure Package (i) there has been no change, nor any development or event involving a prospective change, in the condition (financial or otherwise), results of operations, business, properties or prospects of the Partnership Parties and their subsidiaries, taken as a whole, that has had a Material Adverse Effect, (ii) except as disclosed in or contemplated by the General Disclosure Package, there has been no dividend or distribution of any

kind declared, paid or made by the Partnership Parties on any class of its capital stock or equity interests (other than dividends or distributions made to such entity’s direct or indirect parent), as applicable, and (iii) except as disclosed in or contemplated by the General Disclosure Package, there has been no material adverse change in the capital stock or equity interests, as applicable, short-term indebtedness, long-term indebtedness, net current assets or net assets of the Partnership Parties and their subsidiaries.

(yy) Investment Company Act. The Partnership is not and, after giving effect to the offering and sale of the Offered Units and the application of the proceeds thereof as described in the General Disclosure Package, will not be an “investment company” as defined in the Investment Company Act of 1940 (the “Investment Company Act”).

(zz) Ratings. No “nationally recognized statistical rating organization” as such term is defined for purposes of Rule 436(g)(2) (i) has imposed (or has informed the Partnership that it is considering imposing) any condition (financial or otherwise) on the Partnership’s retaining any rating assigned to the Partnership or any securities of the Partnership or (ii) has indicated to the Partnership that it is considering any of the actions described in Section 7(c)(ii) hereof.

(aaa) PFIC Status. The Partnership was not a “passive foreign investment company” (“PFIC”) as defined in Section 1297 of the United States Internal Revenue Code of 1986, as amended (the “Code”), for the taxable year ended December 31, 2013, and, based on the Partnership’s current and projected income, assets and activities, the Partnership does not believe that it is likely to become a PFIC for any subsequent taxable year.

(bbb) Tax Status. The Partnership is treated as an association taxable as a corporation for United States federal income tax purposes as of the date hereof and will continue to be so treated as of the closing. Except as otherwise provided in this paragraph, each of the Partnership Entities has properly elected to be classified as disregarded as an entity separate from its owner for United States federal income tax purposes.

(ccc) Stamp Taxes. No stamp or other issuance or transfer taxes are payable by or on behalf of the Underwriters in connection with (A) the delivery of the Offered Units in the manner contemplated herein or (B) the sale and delivery by the Underwriters of the Offered Units as contemplated herein.

(ddd) Section 883 Exemption. Based upon the assumptions and subject to the limitations set forth in the Registration Statement, the Disclosure Package and the Prospectus (or any documents incorporated by reference therein), the Partnership qualified for the exemption from United States federal income tax with respect to its U.S. source international transportation income under Section 883 of the Code for the taxable year ending December 31, 2013 and will continue to so qualify for future tax years, provided that less than 50 percent of its Common Units are owned by “5-percent shareholders” (other than Dynagas Holding or its affiliates) as defined in Treasury Regulation Section 1.883-2(d)(3) for more than half the number of days during each such year.

(eee) Immunity. Under the laws of their jurisdiction of formation or incorporation none of the Partnership Parties, their direct or indirect subsidiaries or any of their respective properties has immunity from the jurisdiction of any court or from set-off or any legal proceeding (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise).

(fff) Jurisdiction and Service of Process. The submission by the Partnership Parties in this Agreement to the non-exclusive jurisdiction of the federal or state courts of the United States of America located in the City and County of New York, Borough of Manhattan, constitutes a valid and legally binding obligation of the Partnership and service of process made in the manner set forth in this Agreement will be effective to confer valid personal jurisdiction over the Partnership for purposes of proceedings in such courts under the laws of their respective jurisdiction of formation or incorporation.

(ggg) Enforceability of Foreign Judgments. Pursuant to the terms of this Agreement, the Partnership Parties have agreed to submit to the jurisdiction of any state or federal court in the state of New York in which the relevant suit or proceeding may be instituted. Any final judgment for a fixed or readily calculable sum of money rendered in any state or federal court in the state of New York having jurisdiction in respect of any suit, action or proceeding against the Partnership Parties based upon this Agreement or the transactions contemplated thereby would be declared enforceable against the Partnership Parties by the courts their respective jurisdiction of formation or incorporation of without reexamination of the merits of the cause of action in respect of which the original judgment was given or retrial of the matters adjudicated upon or payment of any stamp, registration or similar tax or duty; provided however, that the Republic of the Xxxxxxxx Islands courts are not bound by a foreign judgment and have the right to review a case on the merits if a motion is made to the court to the effect that there is no merit to the case or the foreign court lacked jurisdiction.

3. Purchase, Sale and Delivery of Offered Units. On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, the Partnership agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Partnership, at a purchase price of $[—] per unit, the number of Firm Units set forth opposite the name of such Underwriter in Schedule A hereto.

The Partnership will deliver the Firm Units to or as instructed by Credit Suisse through the facilities of the Depository Trust Company (“DTC”) for the accounts of the several Underwriters in a form reasonably acceptable to Credit Suisse, against payment of the purchase price by the Underwriters in Federal (same day) funds by wire transfer to an account designated by the Partnership, at the at the office of Xxxxxx & Xxxxxxx LLP, 000 Xxxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000 (the “Closing Location”), at 10:00 A.M., New York time, on [—], 2014, or at such other time not later than seven full business days thereafter as Credit Suisse and the Partnership Parties determine, such time being herein referred to as the “First Closing Date”. For purposes of Rule 15c6-1 under the Securities Exchange Act of 1934, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Units sold pursuant to the offering. A meeting will be held at the Closing Location, at 5:00 P.M. New York City time, on the business day next preceding such First Closing Date, at which meeting the final drafts of the documents to be delivered pursuant to this Agreement will be available for review by the parties hereto.

In addition, upon written notice from Credit Suisse given to the Partnership from time to time not more than 30 days subsequent to the date of the Final Prospectus, the Underwriters may purchase all or less than all of the Optional Units at the purchase price of $[—] per unit. The Partnership agrees to sell to the Underwriters the number of Optional Units specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Units. Such Optional Units shall be purchased for the account of each Underwriter in the same proportion as the number of Firm Units set forth opposite such Underwriter’s name in Schedule A hereto bears to the total number of Firm Units (subject to adjustment by Credit Suisse to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Units. No Optional Units shall be sold or delivered unless the Firm Units previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Units or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by Credit Suisse to the Partnership.

Each time for the delivery of and payment for the Optional Units, being herein referred to as an “Optional Closing Date”, which may be the First Closing Date (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”), shall be determined by Credit Suisse but shall be not later than five full business days after written notice of election to purchase Optional Units is given. The Partnership will deliver the Optional Units being purchased on each Optional Closing Date to or as instructed by Credit Suisse for the accounts of the several Underwriters, in a form reasonably acceptable to Credit Suisse against payment of the purchase price therefore in Federal (same day) funds by wire transfer to

an account at a bank acceptable to Credit Suisse drawn to the order of the Partnership, at the Closing Location. A meeting will be held at the Closing Location at 3:00 p.m., New York City time, on the business day next preceding such Optional Closing Date, at which meeting the final drafts of the documents to be delivered pursuant to this Agreement will be available for review by the parties hereto.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Offered Units for sale to the public as set forth in the Final Prospectus.

5. Certain Agreements of the Partnership Parties. The Partnership Parties agree with the several Underwriters that:

(a) Additional Filings. Unless filed pursuant to Rule 462(c) as part of the Additional Registration Statement in accordance with the next sentence, the Partnership will file the Final Prospectus, in a form approved by Credit Suisse, with the Commission pursuant to and in accordance with subparagraph (1) (or, if applicable and if consented to by Credit Suisse, subparagraph (4)) of Rule 424(b) not later than the earlier of (A) the second business day following the execution and delivery of this Agreement or (B) the fifteenth business day after the Effective Time of the Initial Registration Statement. The Partnership will advise Credit Suisse promptly of any such filing pursuant to Rule 424(b) and provide satisfactory evidence to Credit Suisse of such timely filing. If an Additional Registration Statement is necessary to register a portion of the Offered Units under the Act but the Effective Time thereof has not occurred as of the execution and delivery of this Agreement, the Partnership will file the additional registration statement or, if filed, will file a post-effective amendment thereto with the Commission pursuant to and in accordance with Rule 462(b) on or prior to 10:00 P.M., New York time, on the date of this Agreement or, if earlier, on or prior to the time the Final Prospectus is finalized and distributed to any Underwriter, or will make such filing at such later date as shall have been consented to by Credit Suisse.

(b) Filing of Amendments: Response to Commission Requests. The Partnership will promptly advise Credit Suisse of any proposal to amend or supplement at any time the Initial Registration Statement, any Additional Registration Statement or any Statutory Prospectus and will not affect such amendment or supplementation without Credit Suisse’s consent which shall not be reasonably withheld; and the Partnership will also advise Credit Suisse promptly of (i) the effectiveness of any Additional Registration Statement (if its Effective Time is subsequent to the execution and delivery of this Agreement), (ii) any amendment or supplementation of a Registration Statement or any Statutory Prospectus, (iii) any request by the Commission or its staff for any amendment to any Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iv) the institution by the Commission of any stop order proceedings in respect of a Registration Statement or the threatening of any proceeding for that purpose, and (v) the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Offered Units in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Partnership will use its reasonable 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.

(c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Units is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an 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 is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Partnership will promptly notify Credit Suisse of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriters and the dealers and any other dealers upon request of Credit Suisse, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither Credit Suisse’s consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

(d) Rule 158. As soon as practicable, but not later than the Availability Date (as defined below), the Partnership will make generally available to its security holders an earnings statement covering a period of at least 12 months beginning after the Effective Date of the Initial Registration Statement (or, if later, the Effective Time of the Additional Registration Statement) which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act. For the purpose of the preceding sentence, “Availability Date” means the 45th day after the end of the fourth fiscal quarter following the fiscal quarter that includes such Effective Time, except that, if such fourth fiscal quarter is the last quarter of the Partnership’s fiscal year, “Availability Date” means the 120th day after the end of such fourth fiscal quarter.

(e) Furnishing of Prospectuses. The Partnership will furnish to the Representatives copies of each Registration Statement (three of which will be signed and will include all exhibits), each related Statutory Prospectus, and, so long as a prospectus relating to the Offered Units is (or but for the exemption in Rule 172 would be) required to be delivered under the Act, the Final Prospectus and all amendments and supplements to such documents, in each case in such quantities as Credit Suisse requests. The Final Prospectus shall be so furnished on or prior to 3:00 P.M., New York time, on the business day following the execution and delivery of this Agreement. All other such documents shall be so furnished as soon as available. The Partnership will pay the expenses of printing and distributing to the Underwriters all such documents.

(f) Blue Sky Qualifications. The Partnership will arrange for the qualification of the Offered Units for sale under the laws of such jurisdictions as Credit Suisse reasonably designates and will continue such qualifications in effect so long as required for the distribution, provided that the Company shall not be required to qualify in any such jurisdiction as a foreign corporation, if such requirement arises solely from a request made by Credit Suisse under this Section 5(f).

(g) Reporting Requirements. During the period of three years hereafter, the Partnership will furnish to the Representatives and, upon request, to each of the other Underwriters, as soon as practicable after the end of each fiscal year, a copy of its annual report to unitholders for such year; and the Partnership will furnish to the Representatives (i) as soon as available, a copy of each report and any definitive proxy statement of the Partnership filed with the Commission under the Exchange Act or mailed to unitholders, and (ii) from time to time, such other information concerning the Partnership as Credit Suisse may reasonably request. However, so long as the Partnership is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system, it is not required to furnish such reports or statements to the Underwriters.

(h) Emerging Growth Company Status. The Partnership will promptly notify the Representatives if the Partnership ceases to be an Emerging Growth Company at any time prior to the later of (i) completion of the distribution of the Offered Units within the meaning of the Act and (ii) completion of the Lock-Up Period referred to in Section 5(m) hereof.

(i) Written Testing-the-Waters Communication. If at any time following the distribution of any Written Testing-the-Waters Communication, any event occurs as a result of which such Written Testing-the-Waters Communication 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 at such time not misleading, the Partnership will (i) promptly notify the Representatives so that use of the Written Testing-the-Waters Communication may cease until it is amended or supplemented; (ii) amend or supplement the Written Testing-the-Waters Communication to correct such statement or omission; and (iii) supply any amendment or supplement to the Representatives in such quantities as may be reasonably requested.

(j) Payment of Expenses. The Partnership agrees with the several Underwriters that the Partnership will pay all expenses incident to the performance of the obligations of the Partnership

under this Agreement, including but not limited to any filing fees and other expenses (including fees and disbursements of counsel to the Underwriters) incurred solely in connection with qualification of the Offered Units for sale under the laws of such jurisdictions as Credit Suisse reasonably designates and the preparation and printing of memoranda relating thereto, costs and expenses related solely to the review by the FINRA of the Offered Units (including filing fees and the fees and expenses of counsel (which shall not exceed $25,000) for the Underwriters relating to such review), costs and expenses relating to investor presentations or any “road show” in connection with the offering and sale of the Offered Units including, without limitation, any travel expenses of the Partnership’s officers and employees (such travel expenses shall not include the cost of chartering any airplanes except as set forth in the last sentence of this paragraph) and any other expenses of the Partnership including fees and expenses incident to listing the Offered Units on the NASDAQ and other national and foreign exchanges, fees and expenses in connection with the registration of the Offered Units under the Exchange Act and expenses incurred in distributing preliminary prospectuses and the Final Prospectus (including any amendments and supplements thereto) to the Underwriters and for expenses incurred for preparing, printing and distributing any Issuer Free Writing Prospectuses to investors or prospective investors. The Partnership will not pay for any of the expenses of the Underwriters except as set forth in this paragraph and Section 10 hereof; provided, however, that the Partnership will pay 50% of the expenses associated with any airplane chartered in connection with the road show (and the Underwriters will pay the remaining 50%); provided that the Partnership shall not be required to pay for any expenses associated with any airplane chartered unless the Partnership has agreed to chartering such airplane in writing before such airplane is chartered; and provided further that the Partnership shall pay 100% of the expenses of such airplane if the purchase of the Offered Units by the Underwriters is not consummated for any reason other than (a) any event specified in clause (iii), (vi), (vii) or (viii) of Section 7(c) of this Agreement, or (b) because of the termination of this Agreement pursuant to Section 9 hereof.

(k) Use of Proceeds. The Partnership will use the net proceeds received by it in connection with this offering in the manner described in the “Use of Proceeds” section of the General Disclosure Package and, except as disclosed in the General Disclosure Package and the Final Prospectus, the Partnership does not intend to use any of the proceeds from the sale of the Offered Securities hereunder to repay any outstanding debt owed to any affiliate of any Underwriter.

(l) Absence of Manipulation. The Partnership 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, stabilization or manipulation of the price of any securities of the Partnership to facilitate the sale or resale of the Offered Units. For the avoidance of doubt, the foregoing sentence shall not include any activities by the Underwriters as to which the Partnership Parties make no representation.

(m) Taxes.

All payments to be made by the Partnership hereunder shall be made without withholding or deduction for or on account of any present or future taxes, duties or governmental charges under the laws of the United States or the Xxxxxxxx Islands whatsoever unless the Partnership is compelled by law to deduct or withhold such taxes, duties or charges. In that event, the Partnership shall pay such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made, provided, however, that no such indemnification shall be required if such withholding or deduction is required due to the failure of the Underwriters to provide required tax forms or other information necessary to avoid the imposition of such taxes.

The Partnership Parties represent and agree that, unless they obtain the prior consent of Credit Suisse, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Partnership and Credit Suisse, it has not made and will not make any offer relating to the Offered Units that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Partnership and Credit Suisse is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Partnership represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

8. Indemnification and Contribution. (a) Indemnification of Underwriters. The Partnership Parties will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation,

investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Partnership 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 an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Partnership by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below.

(b) Indemnification of the Partnership Parties. Each Underwriter will severally and not jointly indemnify and hold harmless the Partnership Parties, each of its directors and each of its officers who signs a Registration Statement and each person, if any, who controls the Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”) against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, or other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement at any time, any Statutory Prospectus at any time, the Final Prospectus or any Issuer Free Writing Prospectus or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Partnership by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter under the heading “Underwriting”: (i) the list of Underwriters and their respective participation in the sale of Common Units, (ii) the concession and reallowance figures in paragraph four; (iii) paragraph eight and (iv) the paragraphs related to stabilization, short positions and penalty bids.

(c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a), (b) or (c) above. In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section, as the case may be for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action 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 an indemnified party.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) 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 from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership Parties on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities 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 shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Partnership Parties bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. The Partnership Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(e) 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 in this Section 8(e).

9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Units hereunder on either the First or any Optional Closing Date and the aggregate number of shares of Offered Units that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Offered units that the Underwriters are obligated to purchase on such Closing Date, Credit Suisse may make arrangements satisfactory to the Partnership for the purchase of such Offered Units by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Units that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of Offered Units with respect to which such default or defaults occur exceeds 10% of the total number of Offered Units that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to Credit Suisse and the Partnership for the purchase of such Offered Units by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Partnership, except as provided in Section 10 (provided that if such default occurs with respect to Optional Units after the First Closing Date, this Agreement will not terminate as to the Firm Units or any Optional Units purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Partnership Parties or their officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the

Partnership Parties or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Units. If the purchase of the Offered Units by the Underwriters is not consummated for any reason other than (a) any event specified in clause (iii), (vi), (vii) or (viii) of Section 7(c) of this Agreement, or (b) because of the termination of this Agreement pursuant to Section 9 hereof, the Partnership Parties will, jointly and severally, reimburse the Underwriters for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Units, and the respective obligations of the Partnership Parties and the Underwriters pursuant to Section 8 hereof and the obligations of the Partnership Parties pursuant to Section 10 shall remain in effect. In addition, if any Offered Units have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.

11. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: LCD-IBD; Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated, Xxx Xxxxxx Xxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Syndicate Department, with a copy to ECM Legal; Xxxxxx Xxxxxxx & Co.

12. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder.

13. Representation. The Representatives will act for the several Underwriters in connection with the transactions contemplated by this Agreement, and any action under this Agreement taken by the Representatives jointly or by Credit Suisse will be binding upon all the Underwriters.

14. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

15. Absence of Fiduciary Relationship. The Partnership Parties acknowledge and agree that:

(a) No Other Relationship. The Representatives have been retained solely to act as underwriters in connection with the sale of the Offered Units and that no fiduciary, advisory or agency relationship between the Partnership Parties, on the one hand, and the Representatives, on the other, has been created in respect of any of the transactions contemplated by this Agreement or the Final Prospectus, irrespective of whether the Representatives have advised or is advising the Partnership Parties on other matters;

(b) Arms’ Length Negotiations. The price of the Offered Units set forth in this Agreement was established by the Partnership Parties following discussions and arms-length negotiations with the Representatives and the Partnership Parties are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) Absence of Obligation to Disclose. The Partnership Parties have been advised that the Representatives and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Partnership Parties and that the Representatives have no obligation to disclose such interests and transactions to the Partnership Parties by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver. The Partnership Parties waive, to the fullest extent permitted by law, any claims they may have against the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty and agree that the Representatives shall have no liability (whether direct or indirect) to the Partnership Parties

in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Partnership Parties, including securityholders, employees or creditors of the Partnership Parties.

16.

Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The Partnership Parties hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby (“Related Proceedings”). The Partnership Parties irrevocably and unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in the City of New York (collectively, the “Specified Courts”) and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum. The Partnership Parties irrevocably appoint Xxxxxx & Xxxxxx LLP, as its authorized agent in the Borough of Manhattan in The City of New York upon which process may be served in any such suit or proceeding, and agrees that service of process upon such agent, and written notice of said service to the Partnership Parties by the person serving the same to the address provided in Section 10, shall be deemed in every respect effective service of process upon the Partnership Parties in any such suit or proceeding. The Partnership Parties further agree to take any and all action as may be necessary to maintain such designation and appointment of such agent in full force and effect for a period of seven years from the date of this Agreement. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

The obligation of the Partnership Parties pursuant to this Agreement in respect of any sum due to any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day, following receipt by such Underwriter of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase United States dollars with such other currency; if the United States dollars so purchased are less than the sum originally due to such Underwriter hereunder, the Partnership Parties agree, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Partnership Parties an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter hereunder.
