(ii) if a net operating loss is calculated and the 2017 Prior Payment Amount is a negative number, then SEACOR shall pay, or cause to be paid, to Spinco an amount equal to the sum of (w) the 2017 Prior Payment Amount (viewed as a positive number), (x) the Tax Rate Percentage of such NOL, if any, (y) the Tax Rate Percentage of such NCL, if any, and (z) such FTC, if any; or

(iii) if taxable income is calculated, then SEACOR shall calculate the excess, if any, of (x) the Tax Rate Percentage of such taxable income over (y) the sum of (I) such FTC, if any, and (II) the Tax Rate Percentage of such NCL, if any (such excess, the “2017 Tentative Excess”), and

a. if the amount of the 2017 Tentative Excess is a positive number and the 2017 Prior Payment Amount is a positive number, then Spinco shall pay, or cause to be paid, to SEACOR an amount equal to the sum of (I) the 2017 Prior Payment Amount and (II) the 2017 Tentative Excess;

b. if the amount of the 2017 Tentative Excess is a negative number and the 2017 Prior Payment Amount is a positive number, then SEACOR shall calculate the excess, if any, of (I) the 2017 Tentative Excess (viewed as a positive number) over (II) the 2017 Prior Payment Amount, and if the amount of such excess is a positive number, then SEACOR shall pay, or cause to be paid, to Spinco the amount of such excess, or if the amount of such excess is a negative number, then Spinco shall pay, or cause to be paid, to SEACOR the amount of such excess (viewed as a positive number);

c. if the amount of the 2017 Tentative Excess is a positive number and the 2017 Prior Payment Amount is a negative number, then SEACOR shall calculate the excess, if any, of (I) the 2017 Tentative Excess over (II) the 2017 Prior Payment Amount (viewed as a positive number), and if the amount of such excess is a positive number, then Spinco shall pay, or cause to be paid, to SEACOR the amount of such excess, or if the amount of such excess is a negative number, then SEACOR shall pay, or cause to be paid, to Spinco the amount of such excess (viewed as a positive number); or

d. if the amount of the 2017 Tentative Excess is a negative number and the 2017 Prior Payment Amount is a negative number, then SEACOR shall pay, or cause to be paid, to Spinco an amount equal to the sum of (I) the 2017 Prior Payment Amount (viewed as a positive number) and (II) the 2017 Tentative Excess (viewed as a positive number).

For purposes of determining the net operating loss and NOL or taxable income as well as the NCL, if any, and the FTC, if any, of the Spinco Group for such portion of 2017, such net operating loss and NOL or taxable income as well as NCL and FTC shall be computed solely by reference to the members of the Spinco Group that are members of the SEACOR Consolidated Group for such portion of 2017, and shall be determined as though such members filed on a consolidated basis with Spinco as the common parent.

(c) SEACOR shall prepare and deliver to Spinco a schedule showing in reasonable detail SEACOR’s calculation of any amount payable by SEACOR to Spinco pursuant to Section 2.03(a) or (b) or any amount payable by Spinco to SEACOR pursuant to Section 2.03(a) or (b), as the case may be, and, subject to Section 5.01, Spinco shall pay to SEACOR, or SEACOR shall pay to Spinco, as applicable, the amount shown on such schedule no later than fifteen days following the delivery of such schedule by SEACOR to Spinco.

Section 2.04. Preparation of Tax Returns.

(a) SEACOR shall prepare and timely file (taking into account applicable extensions) all SEACOR Consolidated Returns, and shall timely pay all Taxes (subject to any indemnification rights it may have against Spinco) and shall be entitled to all refunds shown to be due and payable on such Tax Returns. Prior to filing any SEACOR Consolidated Return for the taxable year ended on December 31, 2016 or the taxable year ending on December 31, 2017, SEACOR shall permit Spinco to review and comment on such SEACOR Consolidated Return and shall consider any such comment in good faith, but SEACOR shall not be obligated to accept any such comment.

(b) Unless otherwise required by a Taxing Authority, the Parties agree to prepare and file all Tax Returns, and to take all other actions, in a manner consistent with this Agreement.

(c) Notwithstanding anything to the contrary in this Agreement, for all Tax purposes, the parties shall report any Extraordinary Transactions that are caused or permitted by Spinco or any of its Subsidiaries on the Closing Date after the completion of the Distribution as occurring on the day after the Closing Date pursuant to Treasury Regulation Section 1.1502‑76(b)(1)(ii)(B) or any similar or analogous provision of state, local or foreign Law. SEACOR shall not make a ratable allocation election pursuant to Treasury Regulation Section 1.1502-76(b)(2)(ii)(D) or any similar or analogous provision of state, local or foreign Law.

Section 2.05. Payment of Sales, Use or Similar Taxes. All Transfer Taxes shall be borne equally by SEACOR on the one hand and Spinco on the other. Notwithstanding anything in Section 2.04 to the contrary, the Party required by applicable Law shall remit payment for any Transfer Taxes and duly and timely file such Tax Returns, subject to any indemnification rights it may have against the other Party, which shall be paid in accordance with Section 2.01(c). Spinco, SEACOR and their respective Affiliates shall cooperate in (i) determining the amount of such Taxes, (ii) providing all requisite exemption certificates and (iii) preparing and timely filing any and all required Tax Returns for or with respect to such Taxes with any and all appropriate Taxing Authorities.

Section 2.06. Audits and Proceedings.

(a) Notwithstanding any other provision hereof, if after the Closing Date, an Indemnified Party or any of its Affiliates receives any notice, letter, correspondence, claim or decree from any Taxing Authority (a “Tax Notice”) and, upon receipt of such Tax Notice, believes it has suffered or potentially could suffer any Tax liability for which it is indemnified pursuant to Section 2.01, the Indemnified Party shall promptly deliver such Tax Notice to the Indemnifying Party; provided, however, that the failure of the Indemnified Party to provide the Tax Notice to the Indemnifying Party shall not affect the indemnification rights of the Indemnified Party pursuant to Section 2.01, except to the extent that the Indemnifying Party is more than insignificantly prejudiced by the Indemnified Party’s failure to deliver such Tax Notice. The Indemnifying Party shall have the right to handle, defend, conduct and control, at its own expense, any Tax audit or other proceeding that relates to such Tax Notice; provided, however, that, in all events, each of SEACOR and Spinco shall have the right to participate, at its own expense, in any Tax audit or proceeding relating to Transaction Taxes or to the extent that such Tax audit or proceeding could have an impact on SEACOR or Spinco, as applicable. The Indemnifying Party shall also have the right to compromise or settle any such Tax audit or other proceeding that it has the authority to control pursuant to the preceding sentence subject, in the case of a compromise or settlement that would adversely affect the Indemnified Party, to the Indemnified Party’s consent, which consent shall not be unreasonably withheld, conditioned or delayed. If the Indemnifying Party fails within a reasonable time after notice to defend any such Tax Notice or the resulting audit or proceeding as provided herein, the Indemnifying Party shall be bound by the results obtained by the Indemnified Party in connection therewith. The Indemnifying Party shall pay to the Indemnified Party the amount of any Tax liability within 15 days after a Final Determination of such Tax liability.

(b) If, as a result of a Final Determination, an amended SEACOR Consolidated Return described in Section 2.07(a) or a carryback described in Section 2.07(c), there is an adjustment that would have the effect of increasing or decreasing the Spinco Group’s NOL, taxable income (as computed for U.S. federal income tax purposes), NCL or FTC for any Pre-Closing Period, then Spinco shall pay, or cause to be paid, to SEACOR an amount equal to any decrease in such FTC or the Tax Rate Percentage of any decrease in such NOL or NCL or increase in such taxable income or SEACOR shall pay, or cause to be paid, to Spinco an amount equal to any increase in such FTC or the Tax Rate Percentage of any increase in such NOL or NCL or decrease in such

taxable income, as applicable. For purposes of determining the NOL or taxable income as well as the NCL, if any, and the FTC, if any, of the Spinco Group for such taxable period, such NOL or taxable income as well as NCL and FTC shall be computed solely by reference to the members of the Spinco Group that are members of the SEACOR Consolidated Group for such taxable period, and shall be determined as though such members filed on a consolidated basis with Spinco as the common parent.

Section 2.07. Amended Returns; Carrybacks.

(a) Except as required by Law, SEACOR may not amend any SEACOR Consolidated Return with respect to any Pre-Closing Period (i) to the extent such amendment adversely affects the Tax liability of Spinco or any of its Affiliates without the prior written consent of Spinco or one of its Affiliates (which consent shall not be unreasonably withheld, conditioned or delayed to the extent such amendment would not materially adversely affect the Tax liability of Spinco or any of its Affiliates) and (ii) with respect to all other such amendments, unless SEACOR provides Spinco with an opportunity to review and comment on such amended SEACOR Consolidated Return prior to filing (and SEACOR shall consider any such comment in good faith but shall not be obligated to accept any such comment).

(b) Except as required by Law, without the consent of Spinco, SEACOR may not change any method of accounting for U.S. federal income tax purposes with respect to any Pre-Closing Period.

(c) To the extent permitted by applicable Law, neither Spinco nor any of its Affiliates shall carry back any U.S. federal income Tax Item to a Pre-Closing Period.

Section 2.08. Refunds. Any refund of U.S. federal income Tax received from a Taxing Authority by any member of the SEACOR Group or the Spinco Group with respect to a SEACOR Consolidated Return shall be the property of the SEACOR Group, regardless of whether all or any portion of such refund is attributable to any credit or deduction of any member of the Spinco Group. The Parties acknowledge and agree that this Agreement is intended to create a debtor-creditor relationship between the Parties, and that no member of the SEACOR Group shall be treated as receiving any such refund of U.S. federal income Tax as an agent or trustee of any member of the Spinco Group.

Section 2.09. Earnings and Profits Allocation. SEACOR will advise Spinco in writing of the decrease in SEACOR earnings and profits attributable to the Distribution under Section 312(h) of the Code on or before the first anniversary of the Distribution.

ARTICLE III

TAX-FREE STATUS OF THE DISTRIBUTION

Section 3.01. Representations and Warranties.

(a) Spinco. Spinco hereby represents and warrants or covenants and agrees, as appropriate, that the facts presented and the representations made in (i) the Opinion, (ii) the representation letter from SEACOR addressed to Counsel supporting the Opinion, (iii) the representation letter from Spinco addressed to Counsel supporting the Opinion and (iv) any other materials delivered or deliverable by SEACOR or Spinco in connection with the rendering by Counsel of the Opinion (all of the foregoing, collectively, the “Tax Materials”), to the extent descriptive of the Spinco Group (including the plans, proposals, intentions and

policies of the Spinco Group), are, or will be from the time presented or made through and including the Effective Time and thereafter as relevant, true, correct and complete in all respects.

(b) SEACOR. SEACOR hereby represents and warrants or covenants and agrees, as appropriate, that (i) it has delivered complete and accurate copies of the Tax Materials to Spinco and (ii) the facts presented and the representations made therein, to the extent descriptive of the SEACOR Group (including the plans, proposals, intentions and policies of the SEACOR Group), are, or will be from the time presented or made through and including the Effective Time and thereafter as relevant, true, correct and complete in all respects.

(c) No Contrary Knowledge. Each of SEACOR and Spinco represents and warrants that it knows of no fact (after due inquiry) that may cause the Tax treatment of the Distribution to be other than the Tax-Free Status of the Transactions.

(d) No Contrary Plan. Each of SEACOR and Spinco represents and warrants that neither it, nor any of its Affiliates, has any plan or intent to take any action that is inconsistent with any statements or representations made in the Tax Materials.

Section 3.02. Restrictions Relating to the Distribution.

(a) General. Neither SEACOR nor Spinco shall, nor shall SEACOR or Spinco permit any SEACOR Entity or any Spinco Entity, respectively, to take or fail to take, as applicable, any action that constitutes a Disqualifying Action described in the definitions of SEACOR Disqualifying Action and Spinco Disqualifying Action, respectively.

(b) Restrictions. Prior to the first day following the second anniversary of the Distribution (the “Restriction Period”), Spinco:

(i) shall continue and cause to be continued the active conduct of the SEACOR Marine Business, in each case taking into account Section 355(b)(3) of the Code, in all cases as conducted immediately prior to the Distribution.

(ii) shall not voluntarily dissolve or liquidate (including any action that is a liquidation for U.S. federal income tax purposes).

(iii) shall not (A) enter into any Proposed Acquisition Transaction or, to the extent Spinco has the right to prohibit any Proposed Acquisition Transaction, permit any Proposed Acquisition Transaction to occur, (B) redeem or otherwise repurchase (directly or through an Affiliate) any stock, or rights to acquire stock, except to the extent such repurchases satisfy Section 4.05(1)(b) of Revenue Procedure 96-30 (as in effect prior to the amendment of such Revenue Procedure by Revenue Procedure 2003-48), (C) amend its certificate of incorporation (or other organizational documents), or take any other action, whether through a stockholder vote or otherwise, affecting the relative voting rights of its capital stock (including through the conversion of any capital stock into another class of capital stock), (D) merge or consolidate with any other Person or (E) take any other action or actions (including any action or transaction that would be reasonably likely to be inconsistent with any representation made in the Tax Materials) that in the aggregate (and taking into account any other transactions described in this Section 3.02(b)(iii) and assuming that any outstanding Convertible Notes are converted in connection with such action) would be reasonably likely to have the effect of causing or permitting one or more Persons (whether or not acting in concert) to acquire directly or indirectly stock representing a Fifty-Percent or Greater Interest in Spinco or otherwise jeopardize the Tax-Free Status of the Transactions.

(iv) shall not, and shall not permit any member of its SAG to, sell, transfer, or otherwise dispose of or agree to sell, transfer or otherwise dispose (including in any transaction treated for U.S. federal income tax purposes as a sale, transfer or disposition) of assets (including any shares of capital stock of a Subsidiary) that, in the aggregate, constitute more than 30% of the gross assets of Spinco or more than 30% of the consolidated gross assets of Spinco and members of its SAG. The foregoing sentence shall not apply to (A) sales, transfers, or dispositions of assets in the Ordinary Course of Business, (B) any cash paid to acquire assets from an unrelated Person in an arm’s-length transaction, (C) any assets transferred to a Person that is disregarded as an entity separate from the transferor for U.S. federal income tax purposes or (D) any mandatory or optional repayment (or prepayment) of any indebtedness of Spinco (or any member of its SAG). The percentages of gross assets or consolidated gross assets of Spinco or its SAG, as the case may be, sold, transferred, or otherwise disposed of, shall be based on the fair market value of the gross assets of Spinco and the members of its SAG as of the Closing Date. For purposes of this Section 3.02(b)(iv), a merger of Spinco (or a member of its SAG) with and into any Person shall constitute a disposition of all of the assets of Spinco or such member.

(c) Exceptions. Notwithstanding the restrictions imposed by Section 3.02(b), during the Restriction Period, Spinco may proceed with any of the actions or transactions described therein, if (i) Spinco shall first have requested SEACOR to obtain a ruling or an Unqualified Tax Opinion in accordance with Section 3.03(a) to the effect that such action or transaction will not affect the Tax-Free Status of the Transactions and SEACOR shall have received such a ruling or Unqualified Tax Opinion in form and substance reasonably satisfactory to it, (ii) SEACOR shall have waived in writing the requirement to obtain such ruling or opinion, or (iii) such action or transaction is explicitly contemplated by the Investment Agreement, dated as of November 30, 2015, by and among SEACOR, Spinco and the Investors party thereto, the Convertible Notes as in effect on the Closing Date, or any

other binding written agreement to which Spinco is a party as in effect on the Closing Date. In determining whether a ruling or opinion is satisfactory, SEACOR shall exercise its discretion, in good faith, solely to preserve the Tax-Free Status of the Transactions and may consider, among other factors, the appropriateness of any underlying assumptions or representations used as a basis for the ruling or opinion and the views on the substantive merits.

(d) Certain Issuances of Capital Stock. If Spinco proposes to enter into any Section 3.02(d) Acquisition Transaction or, to the extent Spinco has the right to prohibit any Section 3.02(d) Acquisition Transaction, proposes to permit any Section 3.02(d) Acquisition Transaction to occur, in each case, during the Restriction Period, Spinco shall provide SEACOR, no later than ten (10) days following the signing of any written agreement with respect to any Section 3.02(d) Acquisition Transaction, with a written description of such transaction (including the type and amount of Spinco capital stock to be issued in such transaction).

(e) Tax Reporting. Each of SEACOR and Spinco covenants and agrees that it will not take, and will cause its respective Affiliates to refrain from taking, any position on any income or franchise Tax Return that is inconsistent with the Tax-Free Status of the Transactions.

Section 3.03. Procedures Regarding Opinions and Rulings.

(a) If Spinco notifies SEACOR that it desires to take one of the actions described in Section 3.02(b) (a “Notified Action”), SEACOR shall cooperate with Spinco and use its reasonable best efforts to seek to obtain, as expeditiously as possible, a ruling from the IRS or an Unqualified Tax Opinion for the purpose of permitting Spinco to take the Notified Action unless one of the exceptions set forth in clause (ii) or (iii) of Section 3.02(c) applies. If such a ruling is to be sought, SEACOR shall apply for such ruling and SEACOR and Spinco shall jointly control the process of obtaining such ruling. In no event shall SEACOR be required to file any ruling request under this Section 3.03(a) unless Spinco represents that (i) it has read such ruling request, and (ii) all information and representations, if any, relating to any member of the Spinco Group contained in such ruling request documents are (subject to any qualifications therein) true, correct and complete. Spinco shall reimburse SEACOR for all reasonable costs and expenses incurred by the SEACOR Group in obtaining a ruling or Unqualified Tax Opinion requested by Spinco within ten (10) days after receiving an invoice from SEACOR therefor.

(b) SEACOR shall have the right to obtain a ruling or an Unqualified Tax Opinion at any time in its sole and absolute discretion. If SEACOR determines to obtain such ruling or opinion, Spinco shall (and shall cause each Spinco Entity to) cooperate with SEACOR and take any and all actions reasonably requested by SEACOR in connection with obtaining such ruling or opinion (including by making any representation or reasonable covenant or providing any materials requested by the IRS or the firm issuing such opinion); provided, however, that Spinco shall not be required to make (or cause a Spinco Entity to make) any representation or covenant that is inconsistent with historical facts or as to future matters or events over which it has no control. In connection with obtaining such ruling, SEACOR shall apply for such ruling and shall have sole and exclusive control over the process of obtaining such ruling. SEACOR and Spinco shall each bear its own costs and expenses in obtaining a ruling or Unqualified Tax Opinion requested by SEACOR.

(c) Except as provided in Sections 3.03(a) and (b), neither Spinco nor any Spinco Affiliate shall seek any guidance from the IRS or any other Taxing Authority (whether written, verbal or otherwise) at any time concerning the Distribution (including the impact of any transaction on the Distribution).

If a protective election under Section 336(e) of the Code is made and any failure of the Tax-Free Status of the Transactions results in Taxes (including Taxes attributable to such election) that are not allocated to Spinco pursuant to Section 2.01, then SEACOR shall be entitled to periodic payments from Spinco equal to the product of (x) the Tax Benefit arising from the step-up in Tax basis resulting from such election and (y) the percentage of Taxes arising from such failure that are not allocated to Spinco pursuant to Section 2.01.

ARTICLE V

MISCELLANEOUS

Section5.01. Dispute Resolution. The Parties shall appoint a nationally recognized independent public accounting firm (the “Accounting Firm”) to resolve any dispute as to matters covered by this Agreement. In this regard, the Accounting Firm shall make determinations with respect to the disputed items based solely on representations made by SEACOR and Spinco and their respective representatives, and not by independent review, and shall function only as an expert and not as an arbitrator and shall be required to make a determination in favor of one Party only. The Parties shall require the Accounting Firm to resolve all disputes no later than thirty (30) days after the submission of such dispute to the Accounting Firm, but in no event later than the Due Date for the payment of Taxes or the filing of the applicable Tax Return, if applicable, and agree that all decisions by the Accounting Firm with respect thereto shall be final, conclusive and binding on the Parties. The Accounting Firm shall resolve all disputes in a manner consistent with this Agreement and, to the extent not inconsistent with this Agreement, in a manner consistent with the past practices of SEACOR and its Subsidiaries, except as otherwise required by applicable Law.

Section 5.04. Survival of Covenants. Except as otherwise contemplated by this Agreement, all covenants and agreements of the Parties contained in this Agreement shall survive the Effective Time and remain in full force and effect in accordance with their applicable terms; provided, however, that the representations and warranties and all indemnification for Taxes shall survive until sixty (60) days following the expiration of the applicable statute of limitations (taking into account all extensions thereof), if any, of the Tax that gave rise to the indemnification; provided, further, that, in the event that notice for

indemnification has been given within the applicable survival period, such indemnification shall survive until such time as such claim is finally resolved.

Section 5.05. Termination. Notwithstanding any provision to the contrary, this Agreement may be terminated at any time prior to the Effective Time by and in the sole discretion of SEACOR without the prior approval of any Person, including Spinco. In the event of such termination, this Agreement shall become void and no Party, or any of its officers and directors, shall have any liability to any Person by reason of this Agreement.
