Indemnification

SECTION 6.01. OSG Indemnification.  Subject to the provisions of Section 6.02 and Section 6.03, OSG shall indemnify, defend and hold harmless the OSG MLP Group from and against:  (a) any Covered Environmental Losses relating to the assets contributed by the OSG Entities to the OSG MLP Group prior to or on the Closing Date (the “Contribution Assets”) to the extent that OSG is notified by OSG MLP General Partner of any such Covered Environmental Losses within five years after the Closing Date; (b) Losses to the OSG MLP Group arising from (i) the failure of the OSG MLP Group, immediately after the Closing Date, to be the owner of such valid leasehold interests or fee ownership interests in and to the Contribution Assets, as applicable, as are necessary to enable the OSG MLP Group Members to own or operate the Contribution Assets in substantially the same manner that the Contribution Assets were owned or operated by the OSG Entities immediately prior to the Closing Date or (ii) the failure of the OSG MLP Entities to have by the Closing Date any consent or governmental permit necessary to allow the OSG MLP Entities to own or operate the Contribution Assets in substantially the same manner that the Contribution Assets were owned or operated by the OSG Entities immediately prior to the Closing Date, in each of clauses (i) and (ii) above, to the extent that OSG is notified by OSG MLP General Partner of such Losses within three years after the Closing Date; (c) all U.S. Federal, state and local income tax liabilities attributable to the operation of the Contribution Assets prior to the Closing Date, including any such income tax liabilities that may result from the consummation of the formation transactions for the OSG MLP Group and OSG MLP General Partner but excluding any U.S. Federal, state and local income taxes reserved on the books of the OSG MLP Group on the Closing Date, to the extent that OSG is notified by OSG MLP General Partner of such income tax liabilities within 60 days after the expiration of the applicable statute of limitations for any claims relating thereto; (d) Losses attributable to or associated with ownership or operation of the Retained Assets, whether occurring before or after the Closing Date; and (e) any Retained Liabilities.

SECTION 6.02. Limitation Regarding Indemnification.  The aggregate liability of OSG under Section 6.01(a) above shall not exceed $10,000,000. Furthermore, no claim may be made against OSG for indemnification pursuant to Section 6.01(a)

14

unless the aggregate dollar amount of all claims for indemnification pursuant to such section shall exceed $500,000, in which case OSG shall be liable for claims for indemnification only to the extent such aggregate amount exceeds $500,000. Notwithstanding the foregoing, in the case any Covered Environmental Losses relating to the December 19, 2006 Plea Agreement between OSG and the United States, the limitations on liability contained in this Section 6.02 shall not apply to OSG’s indemnification obligations under Section 6.01(a) above for criminal fines, special assessments or community service payments set forth in Paragraphs 6 and 9 of such Plea Agreement.

SECTION 6.03. Indemnification Procedures.  (a)  OSG MLP General Partner agrees on behalf of OSG MLP and the OSG MLP Group Members, that within a reasonable period of time after any OSG MLP Group member becomes aware of facts giving rise to a claim for indemnification pursuant to Section 6.01, to notify OSG of the nature and specific basis for such claim.

(b)  OSG shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the OSG MLP Group that are covered by the indemnification set forth in Section 6.01, including, without limitation, the selection of counsel, determination of whether to appeal any decision of any court and the settling of any matter or any issue relating thereto; provided, however, that no such settlement shall be entered into without the consent (which consent shall not be unreasonably withheld) of OSG MLP General Partner (with the concurrence of the Conflicts Committee), on behalf of the OSG MLP Group, unless it includes a full release of the OSG MLP Group from such matter or issue, as the case may be.

(c)  OSG MLP and OSG MLP General Partner shall, and shall cause the OSG MLP Group Members to, cooperate fully with OSG with respect to all aspects of the defense of any claims covered by the indemnification set forth in Section 6.01, including, without limitation, the prompt furnishing to OSG of any correspondence or other notice relating thereto that the OSG MLP Group may receive, permitting the names of the members of the OSG MLP Group to be utilized in connection with such defense, the making available to OSG of any files, records or other information of the OSG MLP Group that OSG considers relevant to such defense and the making available to OSG of any employees of the OSG MLP Group; provided, however, that in connection therewith OSG agrees to use reasonable efforts to minimize the impact thereof on the operations of the OSG MLP Group and further agrees to maintain the confidentiality of all files, records and other information furnished by an OSG MLP Group Member pursuant to this Section 6.03. The OSG MLP Group Members, may, at their own option, cost and expense, hire and pay for counsel in connection with any such defense. OSG agrees to keep any such counsel hired by the OSG MLP 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 OSG shall have the right to retain sole control over such defense.

(d)  In determining the amount of any Loss for which any of the members of the OSG MLP Group are entitled to indemnification under this Agreement, the gross

15

amount of the indemnification will be reduced by (i) any insurance proceeds realized by the OSG MLP Group and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the OSG MLP Group as a result of such claim, and (ii) all amounts recovered by the OSG MLP Group under contractual indemnities from any third party. OSG MLP 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 OSG MLP Group in connection with such efforts shall be promptly reimbursed by OSG in advance of any determination of whether such insurance proceeds or other amounts will be recoverable.
