For the past five (5) years, the Partnership Entities have not knowingly engaged in, and are not now knowingly engaged in, and do not have any plans to knowingly engage in, any dealings or transactions with any of their affiliates or any of their subsidiaries, directors, officers or employees, or in any country or territory, that at the time of the dealing or transaction is or was the subject of Sanctions.

(mm) Environmental Laws.

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, except where the failure so to possess would not, individually or in the aggregate, reasonably be expected to result in 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 Parties' disclosure with respect to, any of the Partnership Parties' material accounting policies; (ii) any matter which could result in a restatement of the Partnership Parties' financial statements for any annual or interim period during the current or prior two fiscal years; or (iii) any Internal Control Event.

(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, 2017 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 (other than Dynagas Equity Holdings Ltd.) has properly elected to be classified as disregarded as an entity separate from its owner for United States federal income tax purposes.

(ddd) Section 883 Exemption. Based upon the assumptions and subject to the limitations set forth in the Registration Statement, the General Disclosure Package and the Final 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, 2017 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 Marshall 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.

(hhh) No Integration. Neither the Partnership Parties nor any other person acting on behalf of the Partnership Parties has sold or issued any securities that would be integrated with the offering of the Units contemplated by this Agreement pursuant to the Act, the rules and regulations thereunder or the interpretations thereof by the Commission.

3. Purchase, Sale and Delivery of 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, the principal amount of Firm Units set forth opposite such Underwriter's name in Schedule A hereto at the applicable purchase price set forth on Schedule C hereto.

The Partnership will deliver the Firm Units to or as instructed by the Representatives through the facilities of the Depository Trust Company ("DTC") for the accounts of the several Underwriters in a form reasonably acceptable to the Representatives, 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 Latham & Watkins LLP, 885 Third Avenue, New York, New York 10022 (the "Closing Location"), at 10:00 a.m., New York time, on October 23, 2018, or at such other time not later than seven full business days thereafter as the Representatives 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 Firm Units sold pursuant to the offering.

In addition, upon written notice from the Representatives 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 Option Units. The Partnership agrees to sell to the Underwriters the Option Units specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Option Units. Such Option 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 Option Units 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 Option Units shall be sold or delivered unless the Firm Units previously have been, or simultaneously are, sold and delivered. The right to purchase the Option 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 the Representatives to the Partnership.

Each time for the delivery of and payment for the Option 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 the Representatives but shall be not later than five full business days after written notice of election to purchase Option Units is given. The Partnership will deliver the Option Units being purchased on each Optional Closing Date to or as instructed by the Representatives for the accounts of the several Underwriters, in a form reasonably acceptable to the Representatives against payment of the purchase price therefore in Federal (same day) funds by wire transfer to an account at a bank acceptable to the Representatives drawn to the order of the Partnership, at the Closing Location.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the 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. The Partnership will file the Final Prospectus, in a form approved by the Representatives, with the Commission pursuant to the applicable paragraph of Rule 424(b) not later than the second business day following the execution and delivery of this Agreement. The Partnership will advise the Representatives promptly of any such filing pursuant to Rule 424(b) and provide satisfactory evidence to the Representatives of such timely filing.

(b) Filing of Amendments: Response to Commission Requests. The Partnership will promptly advise the Representatives of any proposal to amend or supplement at any time the Registration Statement, the Preliminary Prospectus or the Final Prospectus and will not affect such amendment or supplementation without the Representatives' consent which shall not be reasonably withheld; and the Partnership will also advise the Representatives promptly of (i) any amendment or supplementation of a Registration Statement or the Final Prospectus, (ii) any request by the Commission or its staff for any amendment to any Registration Statement, for any supplement to the Final Prospectus or for any additional information, (iii) 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 (iv) the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Units in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Partnership will use their 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 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 the Representatives 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 the Representatives, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Representatives' 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 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 Date, 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 the Registration Statement (three of which will be signed and will include all exhibits), the Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto and, so long as a prospectus relating to the 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 the Representatives request. 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; provided, however, that the Partnership may satisfy the requirements of this subsection by making the Registration Statement, the Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto available on its web site or by filing or furnishing such information with the Commission via its Electronic Data Gathering Analysis and Retrieval (EDGAR) system. 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 Units for sale under the laws of such jurisdictions as the Representatives reasonably designate and will continue such qualifications in effect so long as required for the distribution, provided that the Partnership shall not be required to qualify in any such jurisdiction as a foreign corporation, if such requirement arises solely from a request made by the Representatives under this Section 5(f).

(g) Reporting Requirements. During the period of one year 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 the Representatives 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 via EDGAR, 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 Units within the meaning of the Act and (ii) completion of the lock-up period referred to in Section 5(n) hereof.

(i) Written Testing-the-Waters Communications. 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 costs and expenses relating to investor presentations or any "road show" in connection with the offering and sale of the Units including, without limitation, any travel expenses of the Partnership's officers and employees and any other expenses of the Partnership including fees and expenses in connection with the registration of the Units under the Exchange Act and expenses incurred in distributing the 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.

(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 Units 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 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. The Partnership will indemnify and hold harmless the Underwriters against any documentary, stamp or similar issue tax, including any interest and penalties, on the creation, issue and sale of the Units and on the execution and delivery of this Agreement. 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 Marshall 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.

(n) Clear Market. During a period of 30 days from the date of this Agreement, the Partnership Parties will not, without the prior written consent of the Representatives, offer, sell, contract to sell or otherwise dispose of any securities of the Partnership that are substantially similar to the Units.

6. Free Writing Prospectuses. The Partnership Parties represent and agree that, unless they obtain the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Partnership and the Representatives, 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," as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Partnership and the Representatives 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. The Partnership represents that it has satisfied and agrees that it will satisfy the conditions in Rule 433 to avoid a requirement to file with the Commission any electronic road show.

7. Conditions of the Obligations of the Underwriters.

The Representatives may waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder, whether in respect of an Optional Closing Date or otherwise.

8. Indemnification and Contribution.

(a) Indemnification of Underwriters. The Partnership Parties agree to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act and each affiliate of any Underwriter within the meaning of Rule 405 under the Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, the Preliminary Prospectus, the General Disclosure Package or any amendment or supplement thereto, the Final Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus as defined in Rule 433(h) under the Act, any Partnership information that the Partnership has filed or is required to file pursuant to Rule 433(d) under the Act, any "road show" as defined in Rule 433(h) under the Act (a "road show"), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the

Partnership in writing by such Underwriter through the Representatives expressly for use therein.

(b) Indemnification of Partnership Parties. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Partnership Parties, their respective directors and their respective officers who sign the Registration Statement and each person, if any, who controls the Partnership within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Partnership Parties to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Partnership in writing by such Underwriter through you expressly for use in the Registration Statement or any amendment thereof, the Preliminary Prospectus, the General Disclosure Package or any amendment or supplement thereto, the Final Prospectus or any amendment or supplement thereto, any road show or any Issuer Free Writing Prospectus.

(c) Actions against Parties; Notification. In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the "indemnified party") shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by Morgan Stanley & Co. LLC, in the case of parties indemnified pursuant to Section 8(a), and by the Partnership, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. 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 includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) Contribution. To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (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 hand from the offering of the Series B Preferred Units or (ii) if the allocation provided by clause 8(d)(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 8(d)(i) 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, 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 hand in connection with the offering of the Series B Preferred Units shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Series B Preferred Units (before deducting expenses) received by the Partnership Parties and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Final Prospectus, bear to the offering price of the Series B Preferred Units listed on Schedule C hereto. 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 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 by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters' respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective number of Series B Preferred Units they have purchased hereunder, and not joint.

(e) Allocation of Contribution. The Partnership Parties and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 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 that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Series B Preferred Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that 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 remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Units hereunder on either the First or any Optional Closing Date and the aggregate principal amount of Units that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the aggregate principal amount of Units that the Underwriters are obligated to purchase on such Closing Date, the Representatives may make arrangements satisfactory to the Partnership for the purchase of such 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 Units that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate principal amount of Units with respect to which such default or defaults occur exceeds 10% of the aggregate principal amount of Units that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Representatives and the Partnership for the purchase of such 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 Option Units after the First Closing Date, this Agreement will not terminate as to the Firm Units or any Option 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 Units. If the purchase of the Units by the Underwriters is not consummated for any reason other than (a) any event specified in clause (iii), (iv), (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 one counsel) reasonably incurred by them in connection with the offering of the 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 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 Morgan Stanley & Co. LLC, 1585 Broadway, New York, New York 10036, Attn. Equity Syndicate Desk, with a copy to the Legal Department; UBS Securities LLC, 1285 Avenue of the Americas, New York, New York 10019, Attention: Syndicate; Stifel, Nicolaus & Company, Incorporated, 1 South Street, 15th Floor, Baltimore, MD 21202, Attention: Syndicate Department; or, if sent to the Partnership, will be mailed, delivered or telegraphed and confirmed to it at Dynagas LNG Partners LP, 3, Rue Basse, 98000 Monaco, Attention: Michael Gregos; provided, however, that any notice to an Underwriter pursuant to Section 8 will be mailed, delivered or telegraphed and confirmed to such Underwriter.

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 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 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 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 stockholders, unitholders, 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 Seward & Kissel 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 agree 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 11, 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.

[Signature pages follow]

If the foregoing is in accordance with the Representatives' understanding of our agreement, kindly sign and return to the Partnership Parties one of the counterparts hereof, whereupon it will become a binding agreement among the Partnership Parties and the several Underwriters in accordance with its terms.
