As soon as practicable after the Offer is made, the Acquiring Party will deliver to the Offeree all information prepared by or on behalf of or in the possession of such Acquiring Party relating to the Offered Assets (including for the avoidance of doubt, the acquisition price, in the case of Section 2.2(b)) and reasonably requested by the Offeree. As soon as practicable, but in any event, within 30 calendar days after receipt of the Offer, the Offeree shall notify the Acquiring Party in writing that either:

(a) The Board has elected not to cause any Partnership Group Member to purchase such Offered Assets, in which event the Acquiring Party and its Affiliates shall, subject to the other terms of this Agreement (including Section 2.2(b)), be forever free, subject to the provisions of this Agreement, to continue to own, operate and charter such Offered Assets; or

(b) The Board has elected to cause any Partnership Group Member to purchase such Offered Assets, in which event, (i) in the case of an acquisition in accordance with Section 2.2(b), it shall accept such Offer and cause the Partnership Group Member to purchase the Offered Asset on such terms as soon as commercially reasonable after such agreement has been reached, or (ii) in the case of an acquisition in accordance with Section 2.2(c) or Section 2.2(d), the following procedures shall be followed:

(i) After the receipt of the Offer by the Offeree, the Acquiring Party and the Offeree shall negotiate in good faith regarding the fair market value and any applicable Break-up Costs of the Offered Assets that are subject to the Offer and the other terms of the Offer on which the Offered Assets will be sold to the applicable Partnership Group Member.

(ii) If the Acquiring Party and the Offeree are unable to agree on the fair market value (and any applicable Break-up Costs) of the Offered Assets that are subject to an Offer at fair market value on any other terms of the Offer during the Offer Period, the Acquiring Party and the Offeree will engage a mutually-agreed-upon Third-Party Advisor prior to the end of the Offer Period to determine the fair market value of the Offered Assets and/or the other terms on which the Acquiring Party and the Offeree are unable to agree. In determining the fair market value of the Offered Assets and other terms on which the Offered Assets are to be sold, the Third-Party Advisor, as applicable, will have access to the proposed sale and purchase values and terms for the Offer submitted by the Acquiring Party and the Offeree, respectively, and to all information prepared by or on behalf of the Acquiring Party relating to the Offered Assets and reasonably requested by such Third-Party Advisor. Such Third-Party Advisor will determine the fair market value (and any applicable Break-up Costs) of the Offered Assets and/or the other terms on which the Acquiring Party and the Offeree are unable to agree within 30 calendar days of its engagement and furnish the Acquiring Party and the Offeree its determination. The fees and expenses of the Third-Party Advisor, as applicable, will be divided equally between the Acquiring Party and the Offeree. Upon receipt of such determination, the Offeree will have the option, but not the obligation:

7

(A) to cause any Partnership Group Member to purchase the Offered Assets for the fair market value (and any applicable Break-up Costs), and on the other terms determined by the Third-Party Advisor, as soon as commercially practicable after determinations have been made; or

(B) not to cause any Partnership Group Member to purchase such Offered Assets, in which event the Acquiring Party and its Affiliates shall, subject to the other terms of this Agreement, be forever free to continue to own and operate such Offered Assets.

If the Partnership Group Member and Dynagas Holding are unable to agree on the purchase price of the applicable Option Asset and/or the other material terms, Dynagas Holding and the Conflicts Committee shall engage a mutually-agreed-upon independent appraiser, such as an Third-Party Advisor, to determine the fair market value of the applicable Option Asset and/or any other material terms on which the Partnership Group Member and Dynagas Holding are unable to agree. In determining the fair market value of the applicable Option Asset and/or the other material terms on which the applicable Option Asset will be sold, such independent appraiser will have access to the proposed sale and purchase values and terms for the offer submitted by the Partnership Group Member and Dynagas Holding, respectively, and to all information prepared by or on behalf of the Partnership Group Member and Dynagas Holding with respect to the Option Assets and reasonably requested by such independent appraiser. Such independent appraiser will determine the fair market value of the applicable Option Asset and/or the other terms on which the Partnership Group Member and Dynagas Holding are unable to agree within 30 calendar days of its engagement and furnish the Partnership Group Member and Dynagas Holding its determination in writing. The fees and expenses of such independent appraiser will be divided equally between the Partnership Group Member and Dynagas Holding. Upon receipt of such determination, the Partnership Group Member will have the option, but not the obligation, to purchase the applicable Option Asset for the fair market value and on the other terms determined by the independent appraiser as soon as commercially practicable after determinations have been made.

(b) If a Partnership Group Member chooses to exercise its option to purchase the applicable Option Asset under Section 5.2(a), the applicable parties shall enter into a purchase and sale agreement for the purchase and sale of the applicable Option Asset pursuant to which Dynagas Holding shall be obligated to sell the applicable Option Asset to the Partnership Group Member and the Partnership Group Member shall be obligated to purchase such Option Asset from Dynagas Holding on the terms either agreed upon or determined in accordance with Section 5.2(a). The terms of the purchase and sale agreement will include the following:

(i) the Partnership Group Member will deliver a cash purchase price (unless the Partnership Group Member and Dynagas Holding agree that the consideration will be paid by means of equity of the Partnership, an interest-bearing promissory note or other form of consideration);

(ii) the Partnership Group will be entitled to the benefit of the indemnification contained in Article VI of this Agreement;

(iii) Dynagas Holding will provide customary representations and warranties with respect to title to the applicable Option Asset and any other such matters as the Partnership Group Member may approve, which approval will not be unreasonably withheld;

(iv) Dynagas Holding will grant to the Partnership Group Member the right, exercisable at the Partnership Group Member's risk and expense, to make such surveys, tests and inspections of the Optional Vessels as the Partnership Group Member may deem desirable, so long as such surveys, tests or inspections do not damage the Optional Vessels or interfere with the activities of the Dynagas Holding Entities thereon and so long as the Partnership Group Member has furnished Dynagas Holding with evidence that adequate liability insurance is in full force and effect;

(v) the Partnership Group Member will have the right to terminate its obligation to purchase the Option Assets under this Article V and the related purchase and sale agreement if the results of any searches, surveys, tests or inspections conducted pursuant to paragraph (iv) above are, in the reasonable opinion of the Partnership Group Member, unsatisfactory; and

10

(vi) neither Dynagas Holding nor the applicable Partnership Group Member shall have any obligation to sell or buy the applicable Option Asset if any of the consents referred to in Section 5.1(b) above have not been obtained.

(c) If a Partnership Group Member chooses or is deemed to have chosen not to exercise its option to purchase the applicable Option Asset at the price determined by the Third-Party Advisor under Section 5.2(a), all future rights to purchase such Option Asset by the Partnership Group will be extinguished.

ARTICLE VI
INDEMNIFICATION

Section 6.1 Dynagas Holding Indemnification.

Subject to the provisions of Section 6.2 and Section 6.3, Dynagas Holding shall indemnify, defend and hold harmless the Partnership Group from and against: (a) any Covered Environmental Losses relating to the assets that may be acquired, directly or indirectly, by any Partnership Group Member, directly or indirectly, from the Dynagas Holding Entities, including any Optional Interests in Additional Optional Vessels, pursuant to this Agreement and the following six (6) LNG carriers (Clean Energy, Ob River, Amur River, Arctic Aurora, Yenisei River, and Xxxx River), together with any charters or other agreements relating to the operation or ownership of such LNG carriers, that were acquired, directly or indirectly, by the Partnership Group from the Dynagas Holding Entities (the "Contribution Assets") prior to or on their respective acquisition dates ("Acquisition Date") to the extent that Dynagas Holding is notified by the Partnership of any such Covered Environmental Losses within five (5) years after the applicable Acquisition Date; (b) Losses to the Partnership Group arising from (i) the failure of the Partnership Group, immediately after the applicable Acquisition Date, to be the owner of such valid leasehold interests or fee ownership interests in and to the Contribution Assets as are necessary to enable the Partnership Entities to own and operate the Contribution Assets in substantially the same manner that the Contribution Assets were owned and operated by the Dynagas Holding Entities immediately prior to the respective dates on which each such Contribution Asset was acquired by the Partnership Entities or (ii) the failure of the Partnership Entities to have by the applicable Acquisition Date any consent or governmental permit necessary to allow the Partnership Entities to own or operate the Contribution Assets in substantially the same manner that the Contribution Assets were owned and operated by the Dynagas Holding Entities immediately prior to the respective dates on which each such Contribution Asset was acquired by the Partnership Entities, in each of clauses (b)(i) and (b)(ii) above, to the extent that Dynagas Holding is notified by the Partnership of such Losses within three (3) years after the applicable Acquisition Date; and (c) all federal, state, foreign and local income tax liabilities attributable to the operation of the Contribution Assets prior to the applicable Acquisition Date, including any such income tax liabilities of the Dynagas Holding Entities that may result from the consummation of the formation transactions for the Partnership Group and the Partnership, but excluding any federal, state, foreign and local income taxes reserved on the books of the Partnership Group on the applicable Acquisition Date.

Section 6.2 Limitation Regarding Indemnification.

The aggregate liability of Dynagas Holding under Section 6.1(a) above shall not exceed $5,000,000. Furthermore, no claim may be made against Dynagas Holding for indemnification pursuant to Section 6.1(a), unless the aggregate dollar amount of all claims for indemnification pursuant to such section shall exceed $500,000, in which case Dynagas Holding shall be liable for claims for indemnification only to the extent such aggregate amount exceeds $500,000.

Section 6.3 Indemnification Procedures.

(a) The Partnership Group Members agree that within a reasonable period of time after they become aware of facts giving rise to a claim for indemnification pursuant to Section 6.1, they will provide notice thereof in writing to Dynagas Holding specifying the nature of and specific basis for such claim.

11

(b) Dynagas Holding shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Partnership Group that are covered by the indemnification set forth in Section 6.1, including, without limitation, the selection of counsel, determination of whether to appeal any decision of any court and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent (which consent shall not be unreasonably withheld) of the Partnership Group unless it includes a full release of the Partnership Group from such matter or issues, as the case may be.

(c) The Partnership Group Members agree to cooperate fully with Dynagas Holding with respect to all aspects of the defense of any claims covered by the indemnification set forth in Section 6.1, including, without limitation, the prompt furnishing to Dynagas Holding of any correspondence or other notice relating thereto that the Partnership Group may receive, permitting the names of the members of the Partnership Group to be utilized in connection with such defense, the making available to Dynagas Holding of any files, records or other information of the Partnership Group that Dynagas Holding considers relevant to such defense and the making available to Dynagas Holding of any employees of the Partnership Group; provided, however, that in connection therewith Dynagas Holding agrees to use reasonable efforts to minimize the impact thereof on the operations of the Partnership Group and further agrees to maintain the confidentiality of all files, records and other information furnished by a Partnership Group Member pursuant to this Section 6.3. In no event shall the obligation of the Partnership Group to cooperate with Dynagas Holding as set forth in the immediately preceding sentence be construed as imposing upon the Partnership Group an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article VI; provided, however, that the Partnership Group Members may, at their own option, cost and expense, hire and pay for counsel in connection with any such defense. Dynagas Holding agrees to keep any such counsel hired by the Partnership Group reasonably informed as to the status of any such defense (including providing such counsel with such information related to any such defense as such counsel may reasonably request) but Dynagas Holding shall have the right to retain sole control over such defense.

In determining the amount of any Loss for which any of the members of the Partnership Group is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (a) any insurance proceeds realized by the Partnership Group, and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the Partnership Group as a result of such claim, and (b) all amounts recovered by the Partnership Group under contractual indemnities from third Persons. The Partnership Group hereby agrees to use commercially reasonable efforts to realize any applicable insurance proceeds or amounts recoverable under such contractual indemnities; provided, however, that the costs and expenses (including, without limitation, court costs and reasonable attorneys' fees) of the Partnership Group in connection with such efforts shall be promptly reimbursed by Dynagas Holding in advance of any determination of whether such insurance proceeds or other amounts will be recoverable.
