indemnification under this Article III, including, without limitation, the
prompt furnishing to the Indemnifying Party of any correspondence or other
notice relating thereto that the Indemnified Party may receive, permitting the
name of the Indemnified Party to be utilized in connection with such defense,
the making available to the Indemnifying Party of any files, records or other
information of the Indemnified Party that the Indemnifying Party considers
relevant to such defense and the making available to the Indemnifying Party of
any employees of the Indemnified Party; PROVIDED, HOWEVER, that in connection
therewith the Indemnifying Party agrees to use reasonable efforts to minimize
the impact thereof on the operations of the Indemnified Party and further agrees
to maintain the confidentiality of all files, records, and other information
furnished by the Indemnified Party pursuant to this Section 3.3. In no event
shall the obligation of the Indemnified Party to cooperate with the Indemnifying
Party as set forth in the immediately preceding sentence be construed as
imposing upon the Indemnified Party 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 III; PROVIDED, HOWEVER, that the Indemnified Party may, at
its own option, cost and expense, hire and pay for counsel in connection with
any such defense. The Indemnifying Party agrees to keep any such counsel hired
by the Indemnified Party informed as to the status of any such defense, but the
Indemnifying Party shall have the right to retain sole control over such
defense.

          (e)       In determining the amount of any Loss for which the
Indemnified Party is entitled to indemnification under this Agreement, the gross
amount of the indemnification will be reduced by (i) any insurance proceeds
realized or to be realized by the Indemnified Party, and such correlative
insurance benefit shall be net of any incremental insurance premium that becomes
due and payable by the Indemnified Party as a result of such claim and (ii) all
amounts recovered or recoverable by the Indemnified Party under contractual
indemnities from third Persons (together, the "Collateral Sources"). Each
Indemnified Party agrees to use its good faith, reasonable best efforts at all
times to seek recovery from Collateral Sources. If payment is not received by
the Indemnified Party from Collateral Sources within 365 days after the
commencement of the Indemnified Party's good faith, reasonable best efforts to
obtain such payment, then the Indemnified Party shall be entitled to seek
indemnification from the

                                        9
<Page>

Indemnifying Party; provided, the Indemnified Party shall be entitled to seek
indemnification hereunder at any time (i) to the extent any Loss is not
reasonably likely after due investigation to be covered by a Collateral Source
(whether due to a deductible, cap or otherwise) and (ii) if a Collateral Source
is not reasonably expected after due investigation to have sufficient available
net assets to cover such Losses. If, after any advance or payment by an
Indemnifying Party hereunder, the Indemnified Party recovers any amounts from
Collateral Sources with respect to the claim for which an Indemnifying Party has
made payment, the Indemnified Party agrees to promptly refund and repay such
amounts to the Indemnified Party.

          (f)       The date on which written notification of a claim for
indemnification is received by the Indemnifying Party shall determine whether
such claim is timely made within the limitations specified in Section 3.1. No
claim for indemnification pursuant to Section 3.1(a) shall be brought or made
unless, prior to thirty (30) days after the expiration of the applicable time
period set forth in Section 3.1(a)(i), (ii) or (iii), as the case may be, the
Indemnified Party shall have delivered to the Indemnifying Party a good faith
written notice to the effect that the Indemnified Party has incurred Losses
entitled to be indemnified against under Section 3.1(a), which notice specifies
in reasonable detail the amount of such Losses and the nature and basis of such
claim.

                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES

     The K-Sea Entities, jointly and severally, represent and warrant as of the
date of this Agreement as follows:

     SECTION 4.1    INSURANCE. The Insurance Policy is valid, outstanding and
enforceable and is in full force and effect. None of the members of the K-Sea
Group has received any written notice that a defense will be afforded with
reservation of rights or any written notice of cancellation or any other
indication from the issuer of the Insurance Policy that the Insurance Policy is
no longer in full force and effect or that the issuer of the Insurance Policy is
not willing or able to perform its obligation thereunder.

     SECTION 4.2    PRESERVATION OF INDEMNIFICATION CLAIMS. To the extent that
such rights exist or are available to any of the members of the K-Sea Group with
respect to Environmental and Toxic Tort Losses or Special Toxic Tort Losses, no
K-Sea Entity has expressly waived any material rights to indemnification and
other relief under (a) the Purchase Agreement by and among K-Sea Transportation
LLC, a Delaware limited liability company, KSA, EW Holding Corp., a New York
corporation ("Old EWH"), and certain stockholders and subsidiaries of Old EWH,
dated as of March 18, 1999 (the "EW Holding Indemnity Agreement"), (b) the
Contract of Sale and Purchase of Vessels by and between Maritrans Operating
Partners L.P. and K-Sea Transportation LLC, a Delaware limited liability
company, dated as of October 11, 1999 (the "Maritrans Indemnity Agreement"), and
(c) any other agreement entered into in connection with the acquisition or
disposition of assets of any member of the K-Sea Group.

     SECTION 4.3    SUFFICIENCY OF CONVEYANCE.

          (a)       Each of the members of the K-Sea Group is solvent on the
date hereof, and, after diligent analysis of its business, its management
reasonably believes that after giving effect to the transfer of the Conveyed
Assets in exchange for an aggregate of 665,000 Common Units and 4,165,000
Subordinated Units, (i) the fair value of its assets will exceed its
liabilities, (ii) the present fair value of its assets will be greater than the
probable liability on its existing debts as such debts become absolute and
mature, (iii) it will not be rendered insolvent by the transactions contemplated
by this Agreement, the Contribution Agreement and the Registration Statement,
and (iv) it will not be left with an unreasonably small amount of capital with
which to engage in its business.

          (b)       The transfer of the Conveyed Assets as contemplated in the
Contribution Agreement was for reasonably equivalent value and fair market value
(satisfying in each case the requirements under applicable law for "reasonably
equivalent value" and "fair market value") and not with the intent of hindering,
delaying or defrauding the creditors of the K-Sea Group.

          (c)       As of the date hereof, none of the members of the K-Sea
Group contemplates the commencement of insolvency, bankruptcy, liquidation or
consolidation proceedings or the appointment of a receiver, liquidator,
conservator, trustee or similar official in respect of such entity or any of its
respective assets.

                                    ARTICLE V

interpreted so as to prohibit, limit or otherwise restrict any of the K-Sea
Entities from merging, consolidating or otherwise combining with any other K-Sea
Entity.
