Each of the K-Sea Entities has been duly formed and is validly existing in good standing under the Laws of its jurisdiction of formation, and is duly registered or qualified to do business and is in good standing as a foreign corporation, limited liability company, limited partnership or general partnership, as the case may be, in each jurisdiction in which its ownership or lease of property or the conduct of its businesses requires such registration or qualification, except where the failure so to register or qualify would not individually or in the aggregate, reasonably be expected to have a K-Sea Material Adverse Effect. Each of the K-Sea Entities has all corporate, limited liability company, limited partnership or general partnership, as the case may be, power and authority necessary to own or lease its Properties currently owned or leased and to conduct its business as currently conducted, in each case in all material respects as described in the K-Sea SEC Documents.

business combination transaction (a “Sales Transaction”), then K-Sea agrees that it shall provide the Purchaser with an invitation to bid, using substantially the same invitation to bid sent to other potential bidders in such process, and shall provide to the Purchaser substantially the same information relating to the K-Sea Entities that K-Sea provided in such process to such other potential bidders, subject to a confidentiality agreement acceptable to K-Sea containing confidentiality restrictions no more restrictive in the aggregate than those in the confidentiality agreement entered into by any other potential bidder in connection with such process, and the restrictions set forth in Section 5.02(a) shall not apply to any process or transaction described in this Section 5.02(b) for the limited purpose of allowing the Purchaser to bid, negotiate and, with the approval and recommendation of the Board, complete a Sales Transaction as contemplated by this paragraph.

Section 6.01 Indemnification by K-Sea.

From and after the First Transaction Closing, K-Sea agrees to indemnify the Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not involving a Third Party Claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by K-Sea contained herein to be true and correct in all material respects as of the date hereof, as of the First Transaction Closing Date and, if there is a Second Transaction Closing, as of the Second Transaction Closing Date (except with respect to any provisions including the word “material” or words of similar import, with respect to which such representations and warranties must have been true and correct) or (ii) the breach of any of the covenants of K-Sea contained herein; provided, that in the case of the immediately preceding clause (i), such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a Purchaser Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to K-Sea shall constitute the date upon which such claim has been made; provided, further, that the liability of K-Sea shall not be greater in amount than the Purchase Price.

Section 6.02 Indemnification by the Purchaser.

From and after the Closing, the Purchaser agrees to indemnify the K-Sea Entities and their respective Representatives (collectively, “K-Sea Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not involving a Third Party Claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by the Purchaser contained herein to be true and correct in all material respects as of the date hereof, as of the First Transaction Closing Date and, if there is a Second Transaction Closing, as of the Second Transaction Closing Date or (ii) the breach of any of the covenants of the Purchaser contained herein; provided, that in the case of the immediately

preceding clause (i), such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a K-Sea Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to the Purchaser shall constitute the date upon which such claim has been made; provided, further, that the liability of the Purchaser (and its Affiliates, if the Purchaser Transfers a portion or all of the Purchased Units to an Affiliate as permitted by Section 5.01) shall not be greater in amount than the Purchase Price.

Section 6.03 Indemnification Procedure.

(a) A claim for indemnification for any matter not involving a Third Party Claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification that it may claim in accordance with this Article VI, except as otherwise provided in Sections 6.01 and 6.02.

(b) Promptly after any K-Sea Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement (each, a “Third Party Claim”), the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such Third Party Claim but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such Third Party Claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle such Third Party Claim, it shall promptly, and in no event later than five (5) days, notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and/or the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has, within ten (10) Business Days of when the Indemnified Party provides written notice of a Third Party Claim, failed (y) to assume the defense or settlement of such Third Party Claim and employ counsel and (z) notify the Indemnified Party of such assumption, or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may

be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such settlement or legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrongdoing by, the Indemnified Party.

Section 6.04 Other Matters.

All indemnification payments under this Article VI shall be adjustments to the Purchase Price, except as otherwise required by applicable Law.

ARTICLE VII

This Agreement may be terminated at any time prior to the First Transaction Closing:

(a) by the mutual written consent of the Purchaser and K-Sea;

(b) by either the Purchaser or K-Sea, by giving written notice of such termination to the other party, if the First Transaction Closing shall not have occurred on or prior to September 30, 2010 (the “Outside Date”); provided, however, that the right to terminate this Agreement under this Section 7.01(b) shall not be available to any party hereto whose failure to take any action required to fulfill any of such party’s obligations under this Agreement has been the cause of, or resulted in, the failure of the First Transaction Closing to occur prior to such date;

(c) by either the Purchaser or K-Sea, if any court of competent jurisdiction or a Governmental Authority shall have issued an order, decree or ruling or taken any other action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and such order, decree, ruling or other action shall have become final and nonappealable;

(d) By K-Sea, if the Purchaser shall have breached any of its representations, warranties, covenants or agreements contained in this Agreement, which breach (x) would result in the failure of the conditions set forth in Section 2.03(c)(i) or Section 2.03(c)(ii) and (y) cannot be or is not cured prior to the Outside Date; provided, however, that K-Sea is not then in material breach of this Agreement so as to cause any of the conditions set forth in Section 2.03(b)(i) or Section 2.03(b)(ii) not to be satisfied;

(e) By the Purchaser, if K-Sea shall have breached any of its representations, warranties, covenants or agreements contained in this Agreement, which breach (x) would result in the failure of the conditions set forth in Section 2.03(b)(i) or Section 2.03(b)(ii) and (y) cannot be or is not cured prior to the Outside Date; provided, however, that the Purchaser is not then in material breach of this Agreement so as to cause any of the conditions set forth in Section 2.03(c)(i) or Section 2.03(c)(ii) not to be satisfied.

Section 8.03 No Waiver; Modifications in Writing.

(a) Delay. No failure or delay on the part of any party in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy.

(b) Specific Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification or termination of any provision of this Agreement or any other Basic Document (except in the case of the K-Sea Partnership Agreement for amendments adopted pursuant to the terms thereof) shall be effective unless signed by each of the parties hereto or thereto affected by such amendment, waiver, consent, modification or termination. Any amendment, supplement or modification of or to any provision of this Agreement or any other Basic Document, any waiver of any provision of this Agreement or any other Basic Document and any consent to any departure by K-Sea from the terms of any provision of this Agreement or any other Basic Document shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on K-Sea in any case shall entitle K-Sea to any other or further notice or demand in similar or other circumstances.

any party shall not be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty, covenant or agreement contained herein.

Section 8.04 Binding Effect; Assignment.

(a) Binding Effect. This Agreement shall be binding upon K-Sea, the Purchaser and their respective successors and permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and permitted assigns.

(b) Assignment of Rights. The Purchaser’s rights and obligations hereunder (including the right to seek indemnification) may be transferred or assigned in whole or in part by the Purchaser to any Affiliate of the Purchaser without the consent of K-Sea so long as any such assignee is a citizen of the United States within the meaning of 46 U.S.C. Sec. 50501 for the purpose of operating the vessels in the coastwise trade of the United States. Upon any such permitted transfer or assignment, references in this Agreement to the Purchaser (as they apply to the transferor or assignor, as the case may be) shall thereafter apply to such transferee or assignee of the Purchaser unless the context otherwise requires. Without the written consent of K-Sea, which consent shall not be unreasonably withheld, no portion of the rights and obligations of the Purchaser under this Agreement may be assigned or transferred by the Purchaser or such a transferee of Purchased Units to a Person that is not an Affiliate of the Purchaser.

Securities Act pursuant to an effective registration statement. K-Sea shall cooperate with the Purchaser to effect removal of such legend.
