(a) If any Action is commenced in which any Indemnitee is a party which may give rise to a claim for indemnification against any Indemnitor then such Indemnitee shall promptly give notice to the Indemnitor. Failure to notify the Indemnitor will not relieve the Indemnitor of any Liability that it may have to the Indemnitee, except to the extent the defense of such Action is materially and irrevocably prejudiced by the Indemnitee’s failure to give such notice.

-13-

(b) An Indemnitor will have the right to defend against an Indemnification Claim, other than a Indemnification Claim related to Taxes, with counsel of its choice reasonably satisfactory to the Indemnitee if (i) within 15 days following the receipt of notice of the Indemnification Claim the Indemnitor notifies the Indemnitee in writing that the Indemnitor will indemnify the Indemnitee from and against the entirety of any Damages the Indemnitee may suffer resulting from, relating to, arising out of, or attributable to the Indemnification Claim, (ii) the Indemnitor provides the Indemnitee with evidence reasonably acceptable to the Indemnitee that the Indemnitor will have the financial resources to defend against the Indemnification Claim and pay, in cash, all Damages the Indemnitee may suffer resulting from, relating to, arising out of, or attributable to the Indemnification Claim, (iii) the Indemnification Claim involves only money Damages and does not seek an injunction or other equitable relief, (iv) settlement of, or an adverse judgment with respect to, the Indemnification Claim is not in the good faith judgment of the Indemnitee likely to establish a precedential custom or practice materially adverse to the continuing business interests of the Indemnitee, and (v) the Indemnitor continuously conducts the defense of the Indemnification Claim actively and diligently.

(c) So long as the Indemnitor is conducting the defense of the Indemnification Claim in accordance with Section 7.4(b), (i) the Indemnitee may retain separate co-counsel at its sole cost and expense and participate in the defense of the Indemnification Claim, (ii) the Indemnitee will not consent to the entry of any Order with respect to the Indemnification Claim without the prior written consent of the Indemnitor (not to be withheld unreasonably), and (iii) the Indemnitor will not consent to the entry of any Order with respect to the Indemnification Claim without the prior written consent of the Indemnitee (not to be withheld unreasonably, provided that it will not be deemed to be unreasonable for an Indemnitee to withhold its consent (A) with respect to any finding of or admission (1) of any violation of any Law, Order or Permit, (2) of any violation of the rights of any Person, or (3) which Indemnitee reasonably believes could have a material adverse effect on any other Actions to which the Indemnitee or its Affiliates are party or to which Indemnitee has a good faith belief they may become party, or (B) if any portion of such Order would not remain sealed).

(d) Each Party hereby consents to the non-exclusive jurisdiction of any Governmental Authority in which an Action is brought against any Indemnitee for purposes of any Indemnification Claim that an Indemnitee may have under this Agreement with respect to such Action or the matters alleged therein, and agrees that process may be served on such Party with respect to such claim within such jurisdiction.

(e) The foregoing indemnification provisions are in addition to, and not in derogation of, any remedy at Law or in equity that any Party may have with respect to the Transactions.

(b) The Seller’s total liability in respect of all Relevant Claims is limited to the Purchase Price.

(c) Qualifications as to materiality using the term “material” (or any variation thereof, including a Material Adverse Change or Material Adverse Effect) in any representation or warranty shall not be taken into account in determining the amount of any Damages with respect to a breach of such representation or warranty (or failure of any representation or warranty to be true and correct).

(d) The amount of any Seller liability in respect of a Relevant Claim shall be reduced by any amount directly or indirectly received by the Buyer Indemnified Person with respect to such Relevant Claim under any insurance coverage or from any other party alleged to be responsible for such liability.

(e) Seller shall be obligated to indemnify the Buyer Indemnified Person only for those claims giving rise to any Seller liability in respect of a Relevant Claim as to which the Buyer Indemnified Person has given the Seller written notice thereof prior to the end of the applicable survival period.

-15-

7.7 Insurance. The indemnifying party shall be subrogated to the rights of any Indemnitee in respect of any insurance relating to Damages to the extent of any indemnification payments made under this Agreement, and the Indemnitee shall provide all reasonably requested assistance to the indemnifying party in respect of such subrogation.

7.8 No Duplication. Any liability for indemnification under this Agreement shall be determined to avoid duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement.

7.9 Sole Remedy. The Parties agree that, from and after the Closing, the sole and exclusive remedy of any Party or its Affiliates with respect to this Agreement and the transactions provided for in this Agreement shall be limited to the indemnification provisions set forth in this ARTICLE 7 or any other remedy set forth in this Agreement and, in furtherance of the foregoing, each of the Parties, on behalf of itself and its Affiliates, waives and releases the other Party to this Agreement from, to the fullest extent permitted under any applicable Law, any and all rights, claims and causes of action it or its Affiliates may have against the other party to this Agreement with respect to the foregoing matters, except as provided by this Agreement.

7.10 No Special Damages. IN NO EVENT SHALL ANY PARTY BE LIABLE UNDER THIS ARTICLE 7 OR OTHERWISE IN RESPECT OF THIS AGREEMENT FOR EXEMPLARY, SPECIAL, PUNITIVE, INDIRECT, REMOTE, SPECULATIVE OR CONSEQUENTIAL DAMAGES.

9.13 Expenses. Except as otherwise expressly provided in this Agreement, each Party will bear its own costs and expenses incurred in connection with the preparation, execution, and performance of this Agreement and the Transactions including all fees, costs and expenses of agents, representatives, financial or other advisors, legal counsel, and accountants; provided, however, Buyer agrees to reimburse Seller at the Closing for up to $5 million of fees, costs and expenses (the “Reimbursable Costs”) of agents, representatives, financial or other advisors, legal counsel and accountants in conjunction with any financing projects for the Vessel, so long as Seller provides Buyer with copies of invoices in respect of such fees, costs and expenses and wire transfer information to permit Buyer to pay such Reimbursable Costs directly to such entities at least five Business Days prior to the Closing Date. To the extent that the aggregate amount of the Reimbursable Costs is less than $5 million (such difference being the “Reimbursable Costs Adjustment Amount”), the Reimbursable Costs Adjustment Amount shall be added to the first amount stated in Section 1.2 and form part of the Purchase Price and shall be due and payable as part of the Closing Payment in accordance with Section 1.2(b).

9.14 Specific Performance. The parties to this Agreement agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the parties shall be entitled to specific performance of the terms of this Agreement and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at law or in equity.

The word “including” means “including without limitation.” The Parties intend that each representation, warranty, and covenant contained herein shall have independent significance. If any Party has Breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which the Party has not Breached shall not detract from or mitigate the fact that the Party is in Breach of the first representation, warranty, or covenant.
