Amendment No. 2 to the 2006 Agreement

 Exhibit 10.4.3 
 AMENDMENT N0. 2 
 to the 

2006 AGREEMENT FOR THE SALE AND PURCHASE 
 OF ELECTRIC POWER AND ENERGY between 
 CHUGACH ELECTRIC ASSOCIATION, INC., and the
CITY OF SEWARD 
 WHEREAS, Chugach Electric Association, Inc. (“Chugach”) and the City of Seward, Seward Electric
Utilities Division (“Seward”) are parties (hereinafter jointly referred to as the “Parties”) to (1) the 2006 Agreement for the Sale and Purchase of Electric Power and Energy between Chugach Electric Association, Inc., and
the City of Seward; and (2) Amendment No. 1 to that agreement; both of which were effective February 27, 2007 (collectively, the “Agreement”); 
 WHEREAS, the Parties desire to amend the Agreement to facilitate Seward purchasing the electric output of certain small, renewable non-utility power production facilities having a nameplate capacity of
greater than 25 kW, but not greater than 350 kW in the aggregate, that are planned by small power producers in Seward’s service area (“Small Power Projects”); 
 WHEREAS, the intent of the Parties in this Amendment No. 2 to the Agreement (“Amendment No. 2”) is to allow Seward to purchase the electric output from Small Power Projects, subject to the
provisions of Section A of this Amendment No. 2, on terms that are financially neutral to both Chugach and Seward for wholesale power service provided to Seward, without changing Seward’s status under the Agreement as a partially interruptible
requirements customer of Chugach; 
 WHEREAS, the Parties desire to amend the Agreement to facilitate Seward offering net
metering service from eligible on-site generation sources to its retail customers without attendant compensation to Chugach, as detailed in Section B of this Amendment No. 2; 

WHEREAS, the Parties intend that except as specifically stated herein, this Amendment No. 2 to the Agreement shall not in any way
change or diminish the Parties’ respective rights and responsibilities under the Agreement, and shall not be considered as agreement to, or precedent for, future changes in the Parties’ rights and responsibilities under the Agreement; and

 WHEREAS, the changes set forth herein shall not become effective unless and until this Amendment No. 2 is approved by
the City Council of the City of Seward and by the Regulatory Commission of Alaska.

 NOW, THEREFORE, consistent with the above, the Parties agree to amend the Agreement as set
forth below: 
 A. New Section 3(g). 
 The Parties agree to add a new Section 3(g) to the Agreement as follows: 
  

	 	3(g).	Treatment of Small Power Production Projects. 

 (1) For purposes of this Section 3(g), “Small Power Project” shall mean an Eligible Non-Utility Generation facility that has a nameplate capacity of greater than 25 kW, but not greater than
350 kW, is not a net metered generation system, and sells its electric output to Seward. 
 (2) For purposes of
Section 3(g) and Section 3(h), “Eligible Non-Utility Generation” shall mean electric generation from one or more of the following sources: 
 (A) Solar photovoltaic and solar thermal energy; 
 (B) Wind energy; 

(C) Biomass energy, including landfill gas or biogas produced from organic matter, wastewater, anaerobic digesters, or municipal solid
waste; 
 (D) Hydroelectric, geothermal, hydrokinetic energy or ocean thermal energy; and 

(E) Other sources that generally have similar environmental impacts. 

(3) The aggregate installed capacity of all Small Power Projects selling electric output to Seward shall not exceed 350 kW. 

(4) Chugach’s monthly invoice to Seward shall be reduced by a dollar amount equal to the kWh received by Seward from the Small Power
Projects multiplied by Chugach’s tariffed rate for non-firm power purchases for that billing month. Specifically, unless and until an alternative avoided cost calculation is developed, the “Non-firm power rate” on the approved Chugach
Tariff Sheet No. 97 (Purchase and Sales Rates for Qualified Cogeneration and Small Power Production Facilities) for each month shall be used to determine the amount by which Chugach’s invoice shall be reduced based upon Seward’s
purchases from Small Power Projects. At any time prior to the end of this Agreement, Chugach may propose to the Commission an alternative avoided cost calculation to apply to Seward’s purchases from Small Power Projects. Prior to filing any
such proposal, Chugach shall meet with Seward to discuss how the proposed change, if approved, would affect Seward’s monthly invoice. Any changes in the calculation of the avoided cost rate(s) are subject to the standard review and adjudicatory
processes of the Regulatory Commission of Alaska. Seward reserves the right to oppose any such proposal before the Commission.

 (5) Payments made by Seward for purchases from a Small Power Project shall not be less than
the reduction to Seward’s billings from Chugach for the kWh received by Seward from the Small Power Project, as described in Section 3(g)(4), above. 
 (6) Except for the reduction in Chugach’s monthly invoice to Seward computed pursuant to Section 3(g)(4), all rates and resulting invoices charged by Chugach to Seward shall be computed as if
the electric capacity and energy received by Seward from Small Power Projects were received from Chugach. The wholesale billing rates charged by Chugach to Seward shall not be reduced to reflect any contribution of capacity from Small Power
Projects. Energy-related costs other than fuel and purchased power that are presently included in the rates charged by Chugach to Seward shall not be reduced to reflect electric capacity or energy received by Seward from the Small Power Projects.
For the remainder of the term of this Agreement, Chugach’s rates for Seward’s purchases of capacity and energy (including both monthly billing demand and determination of contribution to overall system peak and Total System Demand for
ratemaking purposes) shall be calculated as if the amounts of capacity and energy taken from Small Power Projects by Seward were actually taken from Chugach. 
 (7) For purposes of Chugach’s quarterly Fuel and Purchased Power Cost Adjustment Factor updates (Chugach Tariff Sheets No. 94 et seq.), the amounts credited to Seward pursuant to
Section 3(g)(4) for Seward’s purchases of electric capacity and energy from Small Power Projects will be considered part of Chugach’s system costs. Those costs shall be apportioned to all classes of service, including Seward,
consistent with established cost assignment methodologies. 
 (8) All of Chugach’s remaining obligations under this
Agreement remain unchanged. 
 (9) Before allowing a Small Power Project to interconnect with Seward’s facilities or
equipment, or accepting any electric capacity or energy from a Small Power Project, Seward shall confirm, to Chugach’s satisfaction, its ability to provide Chugach with data that are compliant with and subject to all metering requirements of
this Agreement. Seward shall require by contract with the Small Power Project that the Small Power Project will (A) pay to Chugach the installed cost of the Chugach meter/recorders designated by Chugach as necessary for Chugach to record the
energy and capacity supplied by the Small Power Project to Seward; (B) provide, without charge, a telephone line (dedicated or shared) for telephone access by Chugach to the Chugach meter/recorders; and (C) provide to Chugach, without
charge, full access to any Chugach-owned meter/recorders on the premises of the Small Power Project and any other rights that Chugach has with respect to other meters under this Agreement.

 B. New Section 3(h). 
 The Parties agree to add a new Section 3(h) to the Agreement as follows: 
  

	 	3(h).	Treatment of Net Metered Non-Utility Generation. 

 (1) For purposes of this Section 3(h), “Eligible Non-Utility Generation” shall have the meaning set forth in Section 3(g)(2). 

(2) This Agreement shall not be construed to prohibit Seward from purchasing or receiving from a Seward retail customer the electric
output from an on-site Eligible Non-Utility Generation facility under a net metering service arrangement with the Seward retail customer, provided that the facility has a nameplate capacity of 25 kW or less, and provided that the total nameplate
capacity of all Seward net metered generation facilities is less than 1.5 percent of Seward’s average retail demand. 
 (3)
Chugach’s rates for Seward’s purchases of capacity and energy (including both monthly billing demand and determination of contribution to system peak, total system demand and energy requirements) under this Agreement shall be based on
actual Chugach billing determinants. In this manner, the impact of net metering installations will be to reduce Seward’s billing load and cost responsibility by the amount of actual generation received by Seward from net metered facilities.

 C. No part of this Amendment No. 2 shall be interpreted to have amended the Agreement until this Amendment No. 2 has been
approved by the City Council of the City of Seward and by the RCA. It is expected that the City Council of the City of Seward will take action regarding this Amendment No. 2 on January 23, 2012. The Parties agree to use their best efforts
to obtain prompt approval of this Amendment No. 2 by the RCA. 
 D. Notwithstanding Section C of this Amendment No. 2, Chugach
agrees that Seward may begin negotiations with the owners of Small Power Projects for agreements to purchase the electric output of those projects immediately upon the Parties having signed this Amendment No. 2, and that such negotiations will
not be considered a violation of the Agreement. 
 E. The Parties agree that this Amendment No. 2 shall not preclude Chugach from
negotiating directly with any Small Power Projects or with any other power supplier to purchase electric output.

 MEMBERSHIP INTEREST PURCHASE AGREEMENT 

THIS MEMBERSHIP INTEREST PURCHASE AGREEMENT is made and entered into and effective as of the 10th day of May, 2012 (this “Agreement”), by and between
United Maritime Group, LLC, a Florida limited liability company (“Seller”), and Bulk Handling USA, Inc., a Delaware corporation (“Purchaser”). 

WHEREAS, Seller is the owner of all of the issued and outstanding limited liability company interests (the “Interests”)
of U.S. United Bulk Terminal, LLC, a Louisiana limited liability company (the “Company”); and 
 WHEREAS,
Purchaser desires to purchase, and Seller desires to sell to Purchaser, the Interests, upon the terms and subject to the conditions set forth herein. 
 NOW, THEREFORE, in consideration of the foregoing, the representations, warranties, covenants and agreements set forth in this Agreement, and other good and valuable consideration, the adequacy and
receipt of which are hereby acknowledged, the parties hereby agree as follows: 
 ARTICLE I 

DEFINITIONS 
 Section 1.1 Definitions. Capitalized terms used in this Agreement shall have the meanings set forth in this Agreement. In addition, for purposes of this Agreement, the following terms,
when used in this Agreement, shall have the meanings assigned to them in this Section 1.1. 
 “2012 YTD Repair and
Maintenance Expenditure Amount” means the aggregate amount of (a) capital expenditures for repair, maintenance, replacement or otherwise for purposes of supporting the operations of the Business plus (b) operating costs reflected
as “repairs and maintenance” on the Company’s books and records, in each case paid or made by or on behalf of the Company or any Subsidiary thereof at any time on or after January 1, 2012 and prior to 11:59 p.m., Eastern Standard
Time, on the day immediately prior to the Closing Date, determined on a consolidated basis in a manner consistent with the terms set forth in Section 2.5; provided, however, that the 2012 YTD Repair and Maintenance Expenditure Amount
shall not include any capital expenditures that are Covered Expenditures. 
 “ABL Facility” means that certain
Loan and Security Agreement, dated as of December 22, 2009, by and among Seller, the Company, U.S. United Ocean Services, LLC, U.S. United Barge Line, LLC, U.S. United Inland Services, LLC, Tina Litrico, LLC, Mary Ann Hudson, LLC, Sheila
McDevitt, LLC, and Marie Flood, LLC, as borrowers, certain financial institutions party thereto from time to time, as lenders, and Bank of America, N.A., as Administrative Agent, Co-Collateral Agent and Security Trustee, as amended, modified or
supplemented from time to time, together with any credit facility that refinances (in whole or in part) or replaces the foregoing Loan and Security Agreement referred to in this definition. 

 “Acceptable Claim” means any claim resulting solely from deterioration,
overstressing, or breakage of the underwater components of the Underwater Dock in respect of physical conditions that existed at the Underwater Dock as of the Closing and that are set forth in the Final Report, but in all cases only if the Final
Report concludes that such deterioration, overstressing, or breakage constitutes a Level 1 Condition or a Level 2 Condition as defined in the Standards of Practice for Underwater Inspection according to ASCE Engineering Practice No. 101, as set
forth below. Per the ASCE standard, Level 2 Condition and Level 1 Condition standards are defined as follows: 
  

	 	•	 	 Level 2 - Serious (“Level 2 Condition”) - Advanced deterioration, overstressing, or breakage may have significantly affected the
load-bearing capacity of primary structural components. Local failures are possible and loading restrictions may be necessary. Repairs may need to be carried out on a high-priority basis with urgency; and 

 

	 	•	 	 Level 1 - Critical (“Level 1 Condition”) - Very advanced deterioration, overstressing, or breakage has resulted in localized
failure(s) of primary structural components. More widespread failures are possible or likely to occur, and load restrictions should be implemented as necessary. Repairs may need to be carried out on a very high priority basis with strong urgency;

 provided further, however, that notwithstanding the foregoing, (i) an Acceptable Claim shall not include
any claim arising from deterioration, overstressing, or breakage of, or any other matter relating to, the underwater components of the Underwater Dock if such deterioration, overstressing, breakage or other matter is attributable to long-term or
preexisting deterioration (such as corrosion damage), unless the Final Report has concluded that the structural integrity of the Underwater Dock is immediately threatened, (ii) ratings will only be used to describe the existing in-place
Underwater Dock compared with the structure when new, and (iii) the fact that the Underwater Dock was designed for loads that are lower than the current standards for design will have no influence on the ratings and shall not by itself form the
basis for an Acceptable Claim; provided further, however, that in no event shall an Acceptable Claim cover any claim with respect to the condition of the Company’s docking structures above the water line. 

“Action” means any action, complaint, suit, arbitration or other proceeding, whether civil or criminal, at Law or in
equity, commenced by or before any Governmental Entity or arbitrator. 
 “Affiliate” means a Person that
directly, or indirectly through one or more intermediaries, Controls, or is Controlled by, or is under common Control with, a specified Person. 
 “Agreed Contractor” means a qualified, independent marine structural engineering firm mutually agreed in writing by the parties otherwise meeting the standard for a qualified marine
structural engineering firm as described in ASCE Engineering Practice No. 101. 
 “Agreement” shall have
the meaning set forth in the first paragraph of this Agreement. 
 “Allocation” shall have the meaning set
forth in Section 2.5(b). 

  
 - 2 -

 “Balance Sheet” means the unaudited consolidated balance sheet of the
Company as at December 31, 2011. 
 “Balance Sheet Date” means December 31, 2011.

in excess of the Eligible Direct Claims Amount or that do not relate to an Eligible Direct Claim shall be paid to Purchaser solely out of the Escrow Account in accordance with the terms set forth herein and in the Escrow Agreement and Seller shall

on the Closing Date by Purchaser, Seller and the Escrow Agent. The Escrow Amount shall be held by the Escrow Agent pursuant to the terms of the Escrow Agreement. The Escrow Amount shall serve as security for, and as the sole source of payment of,
the amounts (if any) payable to the Purchaser Indemnitees or Purchaser pursuant to Article VIII, Section 2.3(g)(ii) (except as expressly provided otherwise in such Section 2.3(g)(ii)) and/or Section 2.10, as applicable.

 (a) The Seller Certificate and the Preliminary Statement (and all estimates and calculations of Net Working Capital, Covered Expenditures, Closing Company Debt and 2012 YTD Repair and Maintenance
Expenditure Amount) shall be prepared in accordance with GAAP applied using the same accounting methodologies, principles and procedures used in, and on a basis consistent with, those applied by Seller in preparing the financial statements of the
Company included in the Annual Report of Seller on Form 10-K for the fiscal year ended December 31, 2011 as filed with the SEC prior to the date hereof (including calculating reserves in accordance with the same methodology used to calculate

of the Company and its Subsidiaries have historically been incurred and, in some instances, paid by Seller on behalf of the Company and its Subsidiaries, (B) any such current liabilities that were outstanding as of December 31, 2011 have
been accrued as current liabilities of the Company and its Subsidiaries as reflected on Section 2.5 of the Seller Disclosure Schedule, and (C) to the extent that as of 11:59 p.m., Eastern Standard Time, on the day immediately prior
to the Closing Date, Seller shall have current liabilities that were incurred on behalf of the Company or any Subsidiary thereof that have not been paid prior to such date and time, then (x) if Seller is the obligor with respect thereto (and
therefore liable to pay the amounts owed to the Person entitled to receipt of such payment), then no amounts in respect thereof shall be accrued as a “Current Liability” for purposes of this Agreement, or (y) if the Company or any
Subsidiary thereof is the obligor with respect thereto (and therefore liable to pay the amounts owed to the Person entitled to receipt of such payment), then all amounts in respect thereof shall be accrued as a “Current Liability” for
purposes of this Agreement, notwithstanding anything contained in this Agreement (including this Section 2.5) to the contrary. 

  
 - 25 -

 (b) For the purpose of any purchase price allocation required under Section 1060 or any
other provision of the Code, Purchaser and Seller agree that the Closing Consideration shall be allocated among the assets of the Company and its Subsidiaries for Tax purposes following the Closing in accordance with a schedule prepared by Purchaser
and delivered to Seller within ninety (90) days following the Closing, with such schedule to be agreed upon by Purchaser and Seller within thirty (30) days thereafter (the “Allocation”). Purchaser and Seller agree
(A) to be bound by the Allocation, (B) to act in accordance with the Allocation in the filing of all Tax Returns (including, without limitation, filing Internal Revenue Service Form 8594 (and any supplemental or amended Form 8594) with
their U.S. federal income Tax Returns for the taxable year that includes the Closing Date) and in the course of any Tax audit, Tax examination or Tax litigation relating thereto (and to cooperate in the preparation of any such filings), and
(C) to take no position and cause their respective Affiliates to take no position inconsistent with the Allocation for Tax purposes, unless otherwise required to do so pursuant to a “determination” within the meaning of
Section 1313(a) of the Code. Solely for income tax purposes, Purchaser and Seller agree that if the Subject Vessels have not been sold to a third party prior to the Closing, the assets of the Company and its subsidiaries will include the
Subject Vessels and that the Allocation will allocate a portion of the Closing Consideration to the Subject Vessels. 
 (c)
Seller and Purchaser acknowledge and agree that nothing in this Agreement is intended to produce any double counting of benefits or detriments to Seller or Purchaser by reason of the computations required to be made hereunder in respect of Net
Working Capital, Closing Company Debt, Covered Expenditures and 2012 YTD Repair and Maintenance Expenditure Amount. 

Section 2.6 Covered Proceeding. 
 (a) Following the Closing, Seller (or a designee thereof) shall, at the sole expense of Seller, continue to have sole control and authority with respect to the negotiations in respect of, and the
prosecution, defense and/or settlement of (including, for the avoidance of doubt, any decision to settle), the Covered Proceeding, in each case for and on behalf of the Company and any Affiliate thereof; provided, however, that Seller
shall permit Purchaser or an Affiliate thereof (including the Company or any Subsidiary thereof following the Closing) to participate in such negotiations, settlement or defense through counsel chosen by Purchaser (the fees and expenses of such
counsel shall be borne by Purchaser). 
 (b) In connection with the foregoing, Purchaser shall, and shall cause its Affiliates
(including the Company and its Subsidiaries following the Closing) to, (i) cooperate fully with Seller in the negotiations in respect of, and the prosecution, defense or settlement of, the Covered Proceeding, including by executing or causing
the Company or any Subsidiary thereof to execute such documents or instruments as may be reasonably required in connection therewith, and (ii) furnish such records, information and testimony, and attend such conferences, discovery proceedings,
hearings, trials and appeals, as may be reasonably requested by Seller in connection therewith; provided that Seller shall reimburse Purchaser and the Company for all third party, out-of-pocket and reasonable fees and expenses incurred by any of
them following the Closing in connection with Purchaser’s compliance with this Section 2.6(b). 

  
 - 26 -

 (c) Notwithstanding anything to the contrary herein, Purchaser agrees that following the
Closing and until a final non-appealable award, judgment, resolution or settlement in respect of the Covered Proceeding shall be issued or entered into or agreed to in writing (for the avoidance of doubt, such resolution or settlement requiring the
prior written consent of Seller, which consent shall not be unreasonably withheld, conditioned or delayed ), Purchaser shall not, and shall cause its Affiliates (including the Company and its Subsidiaries following the Closing) not to, take any
action that would be reasonably likely to (i) reduce or otherwise adversely affect in any way (including in respect of timing of payment) any amounts alleged to be payable to the Company or any Subsidiary thereof in respect of the Covered
Proceeding or (ii) otherwise have an adverse effect on the outcome of the Covered Proceeding. 
 (d) In the event that
Purchaser or any Affiliate thereof (including, after the Closing Date, the Company or any Subsidiary thereof) receives a payment or any other proceeds from any Person in respect of the Covered Proceeding, whether due to any settlement, judgment or
other resolution thereof, Purchaser shall, or shall cause an Affiliate thereof to, (a) pay (promptly (and, in any event, within three (3) Business Days) following the receipt thereof by Purchaser or any Affiliate thereof) to Seller an
amount in cash, as additional purchase price, equal to the entire amount of such payment or such other proceeds and (ii) provide written notice to Seller promptly following the receipt thereof and shall thereafter provide to Seller any
additional information that it may reasonably request in connection therewith. Any payment under this Section 2.6 shall be paid to Seller by wire transfer of immediately available funds to the bank account or accounts designated in writing by
Seller to Purchaser. The parties acknowledge that Seller will be treated as retaining ownership for income Tax purposes of the Covered Proceeding and will report the receipt of the payments described herein as income (net of appropriate deductions,
if any) for Tax and financial reporting purposes. Purchaser and Seller agree not to take any position, including, without limitation, for federal, state, foreign or local Tax purposes, that is inconsistent with the intent expressed in this
Section 2.6. 
 Section 2.7 Stacker/Reclaimer Budget Adjustment. No later than two (2) Business
Days prior to the Closing Date, Seller shall request that Shaw GBB, LLC (“Shaw”) deliver to Seller a good faith estimate as of the date of delivery of such estimate (or the most recent practicable date prior to the date of delivery
of such estimate) of the aggregate cost incurred or to be incurred by or on behalf of the Company (including, in the reasonable judgment of Shaw and consistent with the methodology used to determine the Reference Stacker/Reclaimer Cost, an
appropriate contingency for all non-firm or non-fixed cost elements) to complete the purchase, construction, assembly, acceptance testing and commissioning of the stacker/reclaimer as contemplated by the project plan referenced in
Section 1.1(a) of the Seller Disclosure Schedule (such good faith aggregate cost estimate, the “Estimated Total Stacker/Reclaimer Cost”). On the Closing Date, the Base Purchase Price shall (i) if the Estimated Total
Stacker/Reclaimer Cost exceeds the Reference Stacker/Reclaimer Cost, be decreased by an amount equal to the amount of such excess, and (ii) if the Reference Stacker/Reclaimer Cost exceeds the Estimated Total Stacker/Reclaimer Cost, be increased
by an amount equal to such excess (such increase or decrease, as the case may be, being referred to herein as the “Stacker/Reclaimer Budget Closing Adjustment”); provided, however, that in no event shall the Stacker/Reclaimer
Budget 

  
 - 27 -

 
Closing Adjustment exceed $2,000,000. Seller agrees, and agrees to cause the Company, not to amend that certain Stacker/Reclaimer Construction and Erection Agreement dated September 23,
2011, by and between U.S. United Bulk Terminal, LLC and Shanghai Zhenhua Heavy Industries Co., Ltd. to modify the scope thereof in any material respect. 
 Section 2.8 Subject Vessel Adjustment. If the Subject Vessels are sold or otherwise transferred by U.S. United Ocean Services, LLC or any Subsidiary thereof following the Closing Date
in accordance with Section 5 of the UIS-UOS Agreement, then promptly (and, in any event, within three (3) Business Days) following the Vessel Disposition Date (as defined in the UIS-UOS Agreement), Seller shall pay to Purchaser an amount
in cash equal to the amount of the Net Subject Vessel Proceeds. The parties agree that for federal and state income tax purposes, any such sale or other transfer will be treated and reported on all income tax returns as occurring for the account of
Purchaser and any gain or loss recognized on such sale will be reported by Purchaser on its income tax returns, and, consistent with such treatment, the payment of such Net Subject Vessel Proceeds will not be an adjustment to the Closing
Consideration. Purchaser and Seller agree not to take any position, including, without limitation, for federal, state, foreign or local income Tax purposes, that is inconsistent with the intent expressed in this Section 2.8. For the avoidance
of doubt, if the Subject Vessels are sold or otherwise transferred on or prior to the Closing Date in accordance with Section 5.16, this Section 2.8 shall be of no force or effect and neither Seller nor any Affiliate thereof shall be
obligated in any respect of this Section 2.8. 
 Section 2.9 Barge Count. As of 11:59 p.m. Central Time
on the day immediately prior to the Closing Date, Seller shall prepare and deliver to Purchaser a certificate (the “Barge Certificate”) of a duly authorized representative of Seller setting forth the number of Loaded Barges and,
without limitation of the foregoing, if, on the Closing Date, U.S. United Barge Line, LLC is owned by Seller, the Barge Certificate shall also set forth the number of Loaded Barges that are owned by U.S. United Barge Line, LLC (the “Closing
UBL Barge Amount”). If (a) the number of Loaded Barges exceeds the Reference Loaded Barge Amount, the Base Purchase Price shall be decreased by the Barge Adjustment Amount, and (b) the Reference Loaded Barge Amount exceeds the
number of Loaded Barges, then no adjustment shall be made to the Base Purchase Price pursuant to this Section 2.9. If, on the Closing Date, Seller owns U.S. United Barge Line, LLC, then on the day following the Closing Date, Seller and
Purchaser shall collectively compute the number of Loaded Barges that are owned by U.S. United Barge Line, LLC as of 11:59 p.m. Central Time on such day (the “Updated UBL Barge Amount”). Seller and Purchaser shall immediately
thereafter recompute the Barge Adjustment Amount with the only changes to the computation made prior to the Closing as set forth in the Barge Certificate being (i) if the Updated UBL Barge Amount exceeds the Closing UBL Barge Amount, to
increase the number of Loaded Barges by such excess, and (ii) if the Closing UBL Barge Amount exceeds the Updated UBL Barge Amount, to decrease the number of Loaded Barges by such excess, it being agreed that if the Closing UBL Barge Amount and
the Updated UBL Barge Amount shall be equal, then no adjustment to the Barge Adjustment Amount shall be made. If (A) the Barge Adjustment Amount, after giving effect to the recomputation thereof pursuant to the preceding sentence, exceeds the
Barge Adjustment Amount set forth in the Barge Certificate (the “Underpayment Amount”), then the Underpayment Amount shall be included as a Current Liability for purposes of computing Final Working Capital pursuant to
Section 2.3, and (B) the Barge Adjustment Amount set forth in the Barge Certificate exceeds the Barge Adjustment Amount after giving effect to the recomputation thereof pursuant to the preceding sentence (the “Overpayment
Amount”), then the Overpayment Amount shall be included as a Current Asset for purposes of computing Final Working Capital pursuant to Section 2.3.

 Section 2.10 Underwater Dock Condition Purchase Price Adjustment.

 (a) As soon as reasonably practicable following the date hereof (but in any case prior to the Closing), Purchaser and
Seller shall use their respective commercially reasonable efforts to work together to select, hire and enter into any required definitive documentation with the Agreed Contractor (which documentation shall be mutually acceptable to each of the
parties hereto), and concurrently therewith or promptly thereafter (but in any case prior to the Closing) the Independent Diver. Immediately following the Closing, the parties shall instruct the Independent Diver, under the direction of the Agreed
Contractor, to commence an inspection of solely the underwater components of the dock structure of the Company located at Davant, Louisiana (the “Underwater Dock”) as they existed on the Closing Date in accordance with the scope and
upon the terms set forth on Section 2.10 of the Seller Disclosure Schedule (such scope and terms, the “Underwater Dock Inspection Scope”, and such inspection the “Underwater Dock Inspection”). The
parties agree that they shall request the Agreed Contractor to issue to Purchaser and Seller a final engineering inspection report (the “Inspection Report”) no later than six (6) weeks following the Closing Date (provided that
the parties acknowledge that the Inspection Report may not be delivered within such six (6) week period due to weather or other conditions that delay the delivery thereof), which Inspection Report shall be in customary form for a report of this
type and shall, without limitation of the foregoing, set forth in reasonable detail (i) the findings of the Underwater Dock Inspection, (ii) the Agreed Contractor’s conclusion as to whether there exists any condition on the Underwater
Dock that constitutes an Acceptable Claim, and (iii) if the Inspection Report concludes that there is a condition on the Underwater Dock that constitutes an Acceptable Claim, the Inspection Report shall also describe such Acceptable Claim in
reasonable detail (including the reasons why such conditions constitute an Acceptable Claim) and shall set forth the Agreed Contractor’s recommended remediation that should be undertaken in connection with such Acceptable Claim, it being
understood and agreed that such remediation shall be limited to, and the parties shall instruct the Agreed Contractor to limit such remediation recommendation to, such remediation that (i) is required such that after giving effect to the
completion thereof neither a Level 1 Condition nor Level 2 Condition shall exist in respect of such Acceptable Claim and (ii) is such that upon completion of the remediation the structural components involved will be in compliance with the AISC
Manual of Steel Construction. The fees, costs and expenses of the Agreed Contractor and the Independent Diver shall be borne fifty percent (50%) by Seller and fifty percent (50%) by Purchaser, and each of them shall enter into a customary
engagement letter or similar agreement with the Agreed Contractor and Independent Diver, which may provide for indemnification to be provided by Seller and Purchaser on customary terms. 

(b) Following the Closing, including prior to and following the delivery of the Inspection Report, any Inspection Dispute Notice and/or
commencement of any remediation work in respect of any Acceptable Claim or otherwise, Purchaser shall permit, and shall cause its Affiliates (including the Company and its Subsidiaries) and Representatives to permit, Seller and its Representatives
(including the Seller Contractor) to have reasonable access, during normal business hours and upon reasonable notice, to the employees and Representatives of Purchaser and its Affiliates (including the Company and its Subsidiaries) with knowledge of
the issues in 

  
 - 29 -

 
respect of the Underwater Dock and to the Underwater Dock and all documentation, invoices, reports and other information relating thereto, including in respect of any remediation work undertaken
or proposed to be undertaken (including in the Inspection Report) in respect thereof, as Seller or any Representative thereof may reasonably request from time to time. Notwithstanding anything contained herein to the contrary, other than the
Underwater Dock Inspection contemplated by this Section 2.10, in connection with the review of the Inspection Report or any other matter relating to the Underwater Dock or the Underwater Dock Inspection, no party shall have the right to perform
(and no party shall perform) an actual underwater inspection of the Underwater Dock. 
 (c) Each of Purchaser and Seller shall
have thirty (30) days following receipt of the Inspection Report (the “Inspection Review Period”) to review the Inspection Report and the information contained therein (including by retaining the Purchaser Contractor or Seller
Contractor, as the case may be, to assist in the review of the Inspection Report) and to notify the other party in writing (an “Inspection Dispute Notice”) if it disputes any aspect of the Inspection Report or the information
contained therein, including whether an Acceptable Claim shall exist or the remediation thereof recommended by the Agreed Contractor as set forth in the Inspection Report. If any party shall fail to deliver to the other party an Inspection Dispute
Notice prior to the end of the Inspection Review Period, the Inspection Report (as to such party that has so failed to deliver such Inspection Dispute Notice within such time period) shall become final and binding (including as to any remediation
recommended therein that is in compliance with the terms hereof or any conclusion of the Agreed Contractor that there are no Acceptable Claims), provided that failure to deliver an Inspection Dispute Notice prior to the end of the Inspection Review
Period shall not affect the right of any party to dispute any information or positions that are set forth in an Inspection Dispute Notice delivered by any other party hereto. At the end of the Inspection Review Period, in the event that Purchaser
and/or Seller shall have delivered an Inspection Dispute Notice to the other party, Purchaser and Seller shall cooperate in good faith to resolve such dispute as promptly as practicable and, upon such resolution, if any adjustments to the Inspection
Report shall be made in accordance with the agreement of Purchaser and Seller, then Purchaser and Seller shall set forth any such agreement in writing. If Purchaser and Seller are unable to resolve any such dispute within ten (10) days (or such
longer period as Purchaser and Seller shall mutually agree in writing) of the later of Purchaser’s and/or Seller’s delivery of its Inspection Dispute Notice (or, if only one such party has delivered an Inspection Dispute Notice, the
expiration of the Inspection Review Period), then Purchaser and Seller shall mutually designate an independent marine structural engineering Person that is an expert in the matters subject to dispute (the “Independent Underwater Dock
Expert”) and shall submit to such Independent Underwater Dock Expert for resolution any items remaining in dispute; provided, however, that if the parties cannot mutually agree upon the Independent Underwater Dock Expert within ten
(10) days (or such longer period as Purchaser and Seller shall mutually agree in writing) of the expiration of such 10-day period (or such longer period) referenced in the preceding sentence, then any party may take such actions as are required
to request that the New York City office of the American Arbitration Association select the Independent Underwater Dock Expert, and such selection by the American Arbitration Association shall be binding on the parties. 

(d) If the Independent Underwater Dock Expert is retained, Purchaser and Seller shall each present (or may cause their respective
Representatives, including the Purchaser Contractor 

  
 - 30 -

 
or the Seller Contractor, as applicable, to present) in writing and/or orally to the Independent Underwater Dock Expert (A) its proposed resolution of each of the remaining disputed items
(on an item by item basis), including its basis (described in reasonable detail) for asserting that any Acceptable Claim does or does not exist, as applicable, and if such party is asserting that an Acceptable Claim exists or is disputing the
remediation recommended by the Inspection Report or proposed in any Inspection Dispute Notice, the proposed remediation in respect thereof (if any) (each, a “Proposed Resolution”), (B) any materials it wishes to present to
justify the resolution or position it so presents, including any materials prepared by or on behalf of such party, including by the Purchaser Contractor or Seller Contractor, as applicable, and (C) the Inspection Report and/or the Inspection
Dispute Notice, provided that in no event shall either party have any material ex parte communication with the Independent Underwater Dock Expert. The Independent Underwater Dock Expert shall review each of the Proposed Resolutions submitted by
Purchaser and Seller concerning each of the remaining disputed items together with the supporting materials submitted in favor thereof. Purchaser and Seller shall instruct the Independent Underwater Dock Expert to adopt as the resolution of each
remaining disputed item (on an item by item basis) either the Proposed Resolution of Seller or the Proposed Resolution of Purchaser with respect to each such dispute item (and the Independent Underwater Dock Expert shall have no power whatsoever to
reach any other result) and, in reaching its determination between the Purchaser Resolution and the Seller Resolution, the Independent Underwater Dock Expert shall adopt the resolution of each item that in its judgment is closest to the conclusion
that it independently has reached based on a review of all of the information and materials made available to it hereunder. For the avoidance of doubt, with respect to different items in dispute, the Independent Underwater Dock Expert may adopt
Purchaser’s Proposed Resolution of some items and Seller’s Proposed Resolution of other items. The Independent Underwater Dock Expert shall be instructed to use reasonable best efforts to perform its services and reach a final
determination with respect to the matters submitted to it for resolution within thirty (30) days of submission to it of the Proposed Resolutions submitted by Purchaser and Seller concerning each of the remaining disputed items together with the
supporting materials submitted in favor thereof and, in any case, as promptly as practicable after such submission. In resolving any disputed item, the Independent Underwater Dock Expert shall be bound by the provisions of this Section 2.10 and
any other relevant provisions of this Agreement (including the terms of the Underwater Dock Inspection Scope). In connection with the Independent Underwater Dock Expert’s consideration of the dispute(s) submitted to it, each party hereto shall
permit, and cause its Affiliates and Representatives to permit, the Independent Underwater Dock Expert and its Representatives to have reasonable access, during normal business hours and upon reasonable notice, to all of its employees and
Representatives with knowledge of the issues in respect of the Underwater Dock and to the Underwater Dock and all documentation, invoices, reports and other information relating thereto, including in respect of any remediation work undertaken or
proposed to be undertaken in respect thereof, as the Independent Underwater Dock Expert or any Representative thereof may reasonably request from time to time; provided, however, that the determination and other actions taken by the
Independent Underwater Dock Expert in connection with its review of the Proposed Resolutions of the parties and the other materials submitted shall not include the undertaking of an actual underwater inspection by such Independent Underwater Dock
Expert, but shall rather be limited to a review of the materials and other information submitted thereto in accordance with this Section 2.10. Without limiting the foregoing, Purchaser and Seller agree to enter into a customary engagement
letter with the Independent 

  
 - 31 -

 
Underwater Dock Expert (and shall provide customary indemnification thereto, if so requested by the Independent Underwater Dock Expert), and any fees, costs or expenses of the Independent
Underwater Dock Expert (and, if applicable, the American Arbitration Association if engaged pursuant to the definition of Independent Underwater Dock Expert) in respect of its services as contemplated by this Section 2.10 shall be borne fifty
percent (50%) by Seller and fifty percent (50%) by Purchaser. 
 (e) The Inspection Report, (i) if no Inspection
Dispute Notice has been timely delivered by either party, as originally submitted by the Agreed Contractor, or (ii) if an Inspection Dispute Notice has been timely delivered by either Purchaser or Seller, as adjusted pursuant to the resolution
of such dispute in accordance with this Section 2.10 (whether by mutual written agreement of Purchaser and Seller, or by the determination of the Independent Underwater Dock Expert or otherwise), is referred to herein as the “Final
Underwater Dock Report”. 
 (f) If (i) the Final Underwater Dock Report shall state that there are Acceptable
Claims, (ii) the aggregate amount of Eligible Costs and Expenses that shall have been actually expended by Purchaser and its Affiliates shall, at the relevant time of determination, exceed the Underwater Dock Threshold, and (iii) Purchaser
or an Affiliate thereof shall have completed the remediation of the applicable Acceptable Claim and actually paid (or had paid on its behalf other than pursuant to this Section 2.10) all costs and expenses required to be paid in connection
therewith, in each case as evidenced by appropriate invoices, receipts and other documents and records reasonably requested by Seller, then, with respect to any such Acceptable Claim, Purchaser and Seller shall promptly (but in no event more than
five (5) Business Days after the date that Purchaser submits the evidence required hereby) deliver joint written instructions to the Escrow Agent instructing it to pay to Purchaser from the Escrow Account an amount equal to the amount of the
Eligible Costs and Expenses actually paid by Purchaser in connection with effecting remediation of such Acceptable Claim; provided, however, that the aggregate amount that may be paid out of the Escrow Account in respect of the remediation of
any and all Acceptable Claims and any and all Eligible Costs and Expenses paid by Purchaser or any Affiliate thereof in connection therewith shall not exceed $8,000,000, it being agreed that any Eligible Costs or Expenses incurred by Purchaser or
any Affiliate thereof that are in excess of such amount shall be for the sole account of Purchaser or the applicable Affiliate thereof, and neither Seller or any Affiliate thereof shall have any obligation or liability with respect thereto pursuant
to this Section 2.10 or any other provision of this Agreement or any other Transaction Document and no other claim, including any claim pursuant to Article VIII hereof, shall be made with respect thereto. Notwithstanding anything herein to the
contrary, in retaining any contractor or other Person (who may not be an Affiliate of Purchaser or any Affiliate thereof) to perform any remediation or similar services in respect of any Acceptable Claim, Purchaser shall comply with the applicable
provisions of the Escrow Agreement with respect thereto. For the avoidance of doubt, the sole and exclusive source of recovery in respect of each Acceptable Claim and any and all Eligible Costs and Expenses paid in connection therewith shall be the
Escrow Amount, and in no event shall (1) Seller or any Affiliate thereof or any other Person have any direct liability or obligation in respect of any such Acceptable Claim or any such Eligible Costs and Expenses, or (2) Purchaser or any
Affiliate thereof be entitled to recover any Eligible Costs and Expenses or any other amounts in respect of any Acceptable Claim from any source other than the Escrow Account or in an aggregate amount in excess of the Escrow Amount on deposit in the

  
 - 32 -

 
Escrow Account as of any applicable date of determination, it being agreed that on the date (if any) that the Escrow Amount is reduced to zero (0) for any reason (including due to the
release of the Escrow Amount from the Escrow Account in accordance with the terms of the Escrow Agreement), the Purchaser and its Affiliates shall have no right to recover any Eligible Costs and Expenses or other amounts in respect of any Acceptable
Claim. Notwithstanding anything contained herein to the contrary (including the representations and warranties in Article III), (x) neither Purchaser nor any Affiliate thereof shall have the right to receive any payment in respect of any
Acceptable Claim, Seller shall not be required to deliver joint written instructions with respect thereto and Purchaser shall forfeit any such Acceptable Claim (and such Acceptable Claim shall therefore be deemed to not exist), if Purchaser or any
Affiliate thereof has not commenced remediation in respect of an Acceptable Claim within twelve (12) months of the Closing Date, or if any time after the Closing Date Purchaser does not proceed with reasonable diligence to complete the
remediation with respect to such Acceptable Claim, and (y)(A) the rights of Purchaser and its Affiliates set forth in this Section 2.10 are the sole and exclusive remedy with respect to any claim concerning the condition, fitness or any other
matter relating to the Underwater Dock, (B) Seller makes no representation or warranty as to the condition, fitness or any other matter relating to the Underwater Dock, and (C) subject to the terms of this Section 2.10 with respect to
Acceptable Claims, with respect to the condition, fitness and other matters relating to the Underwater Dock, Purchaser hereby acknowledges and agrees that it is acquiring the Underwater Dock on an “as is, where is” and with all faults
basis in its present condition with all known and unknown defects, and without representations, warranties or covenants, express or implied, of any kind or nature. 
 (g) The amount of any and all Eligible Costs and Expenses shall be determined net of any amounts recovered or reasonably expected to be recovered by the Purchaser or any Affiliate thereof (including,
following the Closing, the Company and its Subsidiaries), as applicable, under insurance policies or from other collateral sources (such as contractual indemnities of any Person which are contained outside of this Agreement) with respect to such
Eligible Costs and Expenses. In any case where Purchaser or any Affiliate thereof (including, following the Closing, the Company and its Subsidiaries) recovers, under insurance policies or from other collateral sources, any amount in respect of an
Acceptable Claim for which Purchaser received a payment pursuant to this Section 2.10, Purchaser shall promptly pay over to the Escrow Agent for re-inclusion in the Escrow Account the amount so recovered (after deducting therefrom the amount of
any reasonable out-of-pocket, third-party expenses incurred by Purchaser or such Affiliate in procuring such recovery); provided, however, that if such recovery is made after the Release Date, such amounts shall be paid directly to
Seller; provided further, however, that if, as of the Release Date, there shall be claims pending against the Escrow Amount, then only the amount that is so recovered that is in excess of the aggregate amount of all such pending claims
shall be paid to Seller and the balance shall promptly paid over to the Escrow Agent for re-inclusion in the Escrow Account in accordance with the terms set forth herein. In addition, Purchaser shall not be entitled to any payment pursuant to this
Section 2.10 for any Eligible Costs and Expenses to the extent that Purchaser or any Affiliate thereof (including, following the Closing, the Company and its Subsidiaries) could have, with commercially reasonable efforts, mitigated or prevented
the need for such Eligible Costs and Expenses. 
 (h) The parties acknowledge that the payments contemplated by this
Section 2.10 are intended by the parties to be treated as part of the Closing Consideration and the parties will treat 

  
 - 33 -

 
any such payment as an adjustment to the Closing Consideration for Tax and financial reporting purposes. Purchaser and Seller agree not to take any position, including, without limitation, for
federal, state, foreign or local Tax purposes, that is inconsistent with the intent expressed in this Section 2.10(h). 

ARTICLE III 
 REPRESENTATIONS AND WARRANTIES OF SELLER 
 Except as (a) disclosed in
any Qualifying SEC Report (other than (i) any information that is contained solely in the “Risk Factors” section of such Qualifying SEC Reports and (ii) any forward-looking statements contained in such Qualifying SEC Reports), if
the relevance of such disclosure as an exception to one or more of the following representations and warranties is reasonably apparent, or (b) set forth on the Seller Disclosure Schedule and subject to the terms set forth in
Section 9.6 of this Agreement, Seller represents and warrants to Purchaser as follows: 
 Section 3.1
Organizational Status. Each of the Company and its Subsidiaries is duly organized and validly existing under the Laws of its governing jurisdiction and each (a) has all requisite limited liability company power and authority to carry
on its business as it is now being conducted and (b) is duly qualified to do business and is in good standing in each of the jurisdictions in which the ownership, operation or leasing of its properties and assets and the conduct of the Business
requires it to be so qualified. Seller has made available to Purchaser copies of the Organizational Documents of the Company and its Subsidiaries as in effect on the date hereof. Neither the Company nor any of its Subsidiaries is in default under or
in violation of any of its Organizational Documents in any material respect. 
 Section 3.2 Authorization.
The execution and delivery of this Agreement and the other Transaction Documents by Seller, and the consummation by Seller of the transactions contemplated hereby and thereby, and the performance by Seller of its obligations hereunder and
thereunder, have been duly and validly authorized by all requisite limited liability company action on the part of Seller. This Agreement has been duly executed and delivered by Seller, and (assuming due authorization, execution and delivery by
Purchaser) this Agreement constitutes, and the other Transaction Documents, when executed and delivered by Seller (assuming due authorization, execution and delivery by Purchaser and any other Person party thereto) will constitute, a valid and
binding obligation of Seller, enforceable against Seller in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar Laws relating to or affecting creditors’
rights generally or by general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at Law). 
 Section 3.3 No Conflict. Assuming all Governmental Filings and waiting periods described in or contemplated by Section 3.4 have been obtained or made, or have expired, the
execution and delivery of this Agreement and the other Transaction Documents by Seller and the consummation by Seller of the transactions contemplated hereby and thereby will not (a) contravene, conflict with or violate any applicable Law or
Governmental Order to which any of Seller, the Company or the Subsidiaries of the Company are subject, (b) with or without notice, lapse of time or both, conflict with, result in a violation or breach of, or constitute a default

under, result in the acceleration of or create in any party the right to exercise any remedy or to obtain any additional rights under, or to accelerate, terminate or cancel any Contract to which
Seller or its Subsidiaries (including the Company and its Subsidiaries) is a party or by which Seller or its Subsidiaries (including the Company and its Subsidiaries) is bound or to which the assets of Seller or its Subsidiaries (including the
Company and its Subsidiaries) are subject or (c) contravene, conflict with or violate the Organizational Documents of Seller, the Company or the Subsidiaries of the Company or any resolution adopted by the managers or members (or Persons
exercising similar authority) of Seller, the Company or the Subsidiaries of the Company, other than, in the case of clauses (a) and (b) above, any such violations, conflicts, breaches, defaults, accelerations or rights that would not
reasonably be expected to have a Material Adverse Effect. 
 Section 3.4 Consents; Governmental Filings. None
of Seller, the Company or any Subsidiary of the Company is required to obtain consent from any Person (other than a Governmental Entity) in connection with the execution and delivery of this Agreement or any other Transaction Document or the
consummation or the performance of any of the transactions contemplated therein, except where the failure to obtain any such consent would not reasonably be expected to be material to the Company and its Subsidiaries, taken as a whole. No filings or
registrations with, notifications to, or authorizations, consents or approvals of, a Governmental Entity (collectively, “Governmental Filings”) are required to be obtained or made by any of Seller, the Company or the Subsidiaries of
the Company in connection with the execution and delivery of this Agreement or the other Transaction Documents by Seller or the consummation by Seller of the transactions contemplated hereby or thereby, except (a) compliance with and filings
under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”), (b) compliance with and filings under the Hart-Scott-Rodino Antitrust Improvements Act of 1976
and the rules and regulations promulgated thereunder (the “HSR Act”), (c) Governmental Filings that become applicable as a result of matters specifically related to Purchaser or its Affiliates and (d) such other
Governmental Filings, the failure of which to be obtained or made would not reasonably be expected to be material to the Company and its Subsidiaries, taken as a whole. 
 Section 3.5 Capital Structure; Subsidiaries.

financial information or any memoranda or offering materials or presentations, including any offering memorandum or similar materials made available to Purchaser and its Representatives, are not and shall not be deemed to be or to include

(a) During the one (1) year period following the Closing, Purchaser shall, or shall cause its Affiliates to, provide to each
employee of the Company or any of its Subsidiaries who is employed at the Closing (each, a “Company Employee”), for so long as the Company Employee remains so employed, compensation and employee benefits that, with respect to each
such employee, are not materially less favorable in the aggregate than the compensation and benefits provided to such employee under the Company Plans immediately prior to the Closing. Purchaser shall, or shall cause the Company and its Subsidiaries
to, perform all of their respective obligations under the Company Plans that are maintained or sponsored by the Company as in effect on the Closing Date or as may thereafter be amended in accordance with the terms thereof. 

(b) Purchaser shall, or shall cause its Affiliates to, provide each Company Employee who incurs a termination of employment during the

(c) Purchaser shall, or shall cause its Affiliates, as applicable, to give Company Employees full credit for such Company Employees’
service with the Company and its Affiliates for purposes of eligibility, vesting, and determination of the level of benefits (including for purposes of vacation and severance), but not for purposes of benefit accruals, under any benefit plans

any preexisting condition limitations otherwise applicable to Company Employees and their eligible dependents under any plan of Purchaser or any Affiliate of Purchaser that provides health benefits in which Company Employees may be eligible to

incurred by the Company Employees and their eligible dependents under the health plans in which they participated immediately prior to the Closing during the portion of the calendar year prior to the Closing in satisfying any deductibles,
co-payments, or out-of-pocket maximums under health plans of Purchaser or any of its Affiliates in which they are eligible to participate after the Closing in the same plan year in which such deductibles, co-payments, or out-of-pocket maximums were
incurred and (iii) waive any waiting period limitation or evidence of insurability requirement that would otherwise be applicable to a Company Employee and his eligible dependents on or after the Closing, in each case to the extent that such
Company Employee or eligible dependent had satisfied any similar limitation or requirement under an analogous Company Plan prior to the Closing. 
 (e) Nothing contained in this Section 5.2, express or implied, is intended to confer upon any Company Employee any right to continued employment for any period or continued receipt of any specific
employee benefit, or shall constitute an amendment to or any other modification of any Company Plan. Further, this Section 5.2 shall be binding upon and inure solely to the benefit of each of the parties to this Agreement, and nothing in this
Section 5.2, express or implied, is intended to confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 5.2.

regulations of any stock exchange upon which the securities of Purchaser, Seller or any of their respective Affiliates are listed, in which case the party required to issue or make the release or announcement shall allow (or cause its Affiliate to
allow) the other party reasonable time to comment on such release or announcement in advance of such issuance or the making thereof, (b) Purchaser, Seller or any of their respective Affiliates may disclose this Agreement, the other Transaction

Contract requiring Seller or any Affiliate thereof to make periodic filings with the SEC, (c) that Seller shall be permitted to make, or cause the Company to make, announcements from time to
time to the respective employees, customers, suppliers and other business relations of Seller, the Company and their respective Affiliates (including in connection with seeking the consent or approval of any Person pursuant to any Contract to which
Seller, the Company or any of their respective Subsidiaries is a party or otherwise bound) and otherwise as Seller may reasonably determine is necessary to comply (or cause the Company or any other Subsidiary of Seller to comply) with applicable Law
or the requirements of any Contract to which Seller or the Company or any of their respective Subsidiaries is a party or otherwise bound, (d) for such announcements or releases required to be made to comply with Section 5.6, (e) that
nothing contained herein shall limit or restrict the right of Seller, Purchaser or any of their respective Affiliates in respect of any Action that may arise or be commenced between Seller, any parent company of Seller or the Company, on the one
hand, and Purchaser or any Affiliate thereof, on the other hand, and (f) that nothing shall limit or restrict the right of Seller, Purchaser or any of their respective Affiliates to make internal announcements to their employees, so long as

 Section 5.4
Confidentiality. The parties acknowledge and agree that the Confidentiality Agreement between Seller and Oiltanking Holding Americas, LLC, dated December 1, 2011 (the “Confidentiality Agreement”), shall remain in
full force and effect in accordance with the terms set forth therein, and that any and all material and information provided by or on behalf of Seller pursuant to this Agreement or any other Transaction Document, including any information provided
pursuant to Section 5.5, shall be subject to the terms set forth therein. For the avoidance of doubt, if this Agreement is, for any reason, terminated prior to the Closing, the Confidentiality Agreement shall continue in full force and effect
as provided in Section 7.2. 
 Section 5.5 Access to Information. 

(a) Subject to the terms set forth in Section 5.4 and this Section 5.5, Seller shall cause the Company and its Subsidiaries to
afford Purchaser and its Representatives reasonable access, during normal business hours and upon reasonable notice, to the properties, offices and other facilities of the Company and its Subsidiaries and to their books and records, and shall
furnish Purchaser with available financial, operating and other data and information with respect to the business and properties of the Company and its Subsidiaries as Purchaser may reasonably request. In exercising its rights hereunder, Purchaser
shall (and shall cause each of its Representatives to) conduct itself so as not to interfere in the conduct of the business of the Company and its Subsidiaries prior to Closing. Purchaser acknowledges and agrees that any contact by Purchaser and its
Representatives with officers, employees, customers or agents of the Company and its Subsidiaries hereunder shall be arranged and supervised by representatives of Seller or any designee thereof, and that unless Seller otherwise provides its prior
written consent, Purchaser shall not, and shall cause its Representatives not to, contact or discuss with any officer, employee, customer or agent or other business relation of the Company or any Subsidiary thereof any matters pertaining to the
Company or any Subsidiary thereof, any of their respective businesses or operations or the transactions contemplated by this Agreement or any other Transaction Document. Notwithstanding anything to the contrary set forth in this Agreement,

neither Seller nor any of its Affiliates (including the Company and its Subsidiaries) shall be required to disclose to Purchaser or any agent or Representative thereof any information
(a) relating to any sale or divestiture process conducted by Seller for the Company, any Subsidiary thereof or the Business or Seller’s (or its Representatives’) evaluation of the Company, any Subsidiary thereof or the Business in
connection therewith, including projections, financial information or other information relating thereto, or (b) if doing so could in the reasonable judgment of Seller violate any Contract or Law to which Seller or any of its Affiliates
(including the Company and its Subsidiaries) is a party or to which it is subject or which it believes in good faith could result in a loss of the ability to successfully assert a claim of privilege (including the attorney-client and work-product
privileges), it being understood and agreed that Seller may elect to limit, or cause the Company or any Subsidiary thereof to limit, disclosure of any information to certain Persons designated as a “clean team” by Purchaser (which Persons
must be reasonably acceptable to Seller). In addition, notwithstanding anything contained in this Agreement to the contrary, without the prior written consent of Seller, none of Purchaser or its Representatives shall have any right to perform or
conduct, or cause to be performed or conducted, any environmental sampling or testing at, in, on or underneath the Real Property.

is necessary or advisable under the HSR Act. Seller and Purchaser shall keep, and shall cause their respective Affiliates to keep, each other timely apprised of the status of any communications with, and any inquiries or requests for additional
information from such Governmental Entity, and shall comply, and shall cause their respective Affiliates to comply, promptly with any such inquiry or request. Neither party shall agree, or permit any Affiliate thereof to agree, to participate in any
meeting, whether in person or telephonically, with any Governmental Entity in respect of any such filings, investigation or other inquiries unless it consults with the other party in advance, and to the extent permitted by such Governmental Entity,
gives the other party the opportunity to attend and participate thereat. 

  
 - 54 -

 (b) Purchaser shall, and shall cause its Affiliates to, use its reasonable best efforts to
avoid or eliminate each and every impediment under any antitrust, competition or other Law or in connection with any Purchaser Governmental Filings that may be asserted (or threatened to be asserted) by any Governmental Entity so as to enable the
parties to expeditiously close the transactions contemplated by this Agreement and the other Transaction Documents on the terms set forth herein. In addition, without limiting the generality of the foregoing, Purchaser and Seller agree to use their
respective reasonable best efforts to take promptly, and cause their respective Affiliates to take promptly, any and all steps necessary to oppose, and to attempt to vacate or lift, any Governmental Order or other restraint or limitation imposed by
any Governmental Entity (or threatened to be imposed by any Governmental Entity) that would have the effect of, or be reasonably likely to have the effect of, making the transactions contemplated by this Agreement or the other Transaction Documents
illegal or otherwise prohibiting or delaying the consummation of such transactions. 
 (c) Purchaser and Seller shall cooperate
with one another, and cause their Affiliates to so cooperate, in determining whether any action by or in respect of, or filing with, any Governmental Entity (excluding the actions and filings described in subsections (a) and (b) of this
Section 5.6) is required or reasonably appropriate, or any action, consent, approval or waiver from any party to any Company Contract is required or reasonably appropriate, in connection with the consummation of the transactions contemplated by
this Agreement and the other Transaction Documents. Subject to the terms and conditions of this Agreement and the Confidentiality Agreement, in taking such actions or making any such filings, the parties shall furnish such information, and cause
their Affiliates to furnish such information, as may be required in connection therewith and timely seek to obtain any such actions, consents, approvals or waivers. 
 Section 5.7 Director and Officer Liability; Indemnification. 
 (a) From and after the Closing and prior to the sixth (6th) anniversary of the Closing, Purchaser shall not permit the Company or any Subsidiary thereof to amend (whether by merger, dissolution, liquidation or otherwise) the Organizational Documents of the
Company or any Subsidiary thereof as in effect at the Closing in a manner that would diminish in any respect the indemnification and contribution rights and the provisions contained therein regarding the elimination or limitation of liability, in
each case of the current and former officers, directors, managing members and members of the Company and its Subsidiaries thereunder and any other Persons entitled to indemnification, contribution or liability limitation thereunder (collectively,
the “Company Indemnitees”), in respect of acts or omissions (or alleged acts or omissions) occurring at or prior to the Closing, including in respect of any acts or omissions (or alleged acts or omissions) taken or not taken in
connection with the execution and delivery of this Agreement or any other Transaction Document or the consummation of the transactions contemplated hereby and thereby. 
 (b) Prior to the Closing, Purchaser shall purchase an extended reporting period endorsement (the “Tail Insurance Policy”) under Seller’s existing directors’ and officers’
liability insurance coverage (including employment practices and fiduciary liability insurance) for the benefit of the Company Indemnitees that shall provide such Persons with coverage for six (6) years following the Closing of not less than
the existing coverage and having other terms no 

  
 - 55 -

 
less favorable to the insured Persons thereunder than the directors’ and officers’ liability insurance coverage presently maintained by Seller for acts or omissions occurring at or
prior to the Closing Date; provided, however, that such Tail Insurance Policy shall only apply to time periods beginning December 4, 2007 and shall only cover the Company Indemnitees for acts or omissions with respect to the
Company or its Subsidiaries. Following the Closing, Purchaser shall cause the Tail Insurance Policy to remain in full force and effect and shall not, and shall not cause or permit any Affiliate thereof to, amend, waive, modify or otherwise alter the
terms thereof.

(i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to
any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Company or any such Subsidiary, as the case may be, shall assume the obligations of such Person that are set forth in this
Section 5.7. 
 (d) The provisions of this Section 5.7 will survive the Closing and are intended
to be for the benefit of, and will be enforceable by, each of the Company Indemnitees and their respective successors, representatives and heirs, and their rights under this Section 5.7 are in addition to, and will not be deemed to be exclusive
of, any other rights to which any such Person is entitled, whether pursuant to applicable Law, agreement or otherwise. Notwithstanding anything contained herein to the contrary, if, at any time prior to the sixth (6th) anniversary of the Closing, any Company Indemnitee delivers to
Purchaser or the Company a written notice asserting a claim for indemnification under any of the provisions set forth in this Section 5.7 or any of the documents referred to herein, then the claim asserted in such notice (and the related
indemnification obligations provided for hereunder or in any such document referred to herein) shall survive the sixth
(6th) anniversary of the Closing until such time as
such claim is fully and finally resolved. 
 Section 5.8 Reasonable Best Efforts. Upon the terms and subject
to the conditions herein provided, except as otherwise provided in this Agreement and without limiting the application of the provisions of Section 5.6, each of the parties agrees to use, and to cause their respective Affiliates to use, its or
their reasonable best efforts to take or cause to be taken all actions, to do or cause to be done and to assist and cooperate with the other party in doing all things necessary, proper or advisable under applicable Laws to consummate and make
effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement and the other Transaction Documents, including: (a) the satisfaction of the conditions precedent to the obligations of any of the parties set
forth herein; (b) the obtaining of applicable consents, waivers or approvals of any Governmental Entities or third parties; (c) the defending of any Actions challenging this Agreement or the other Transaction Documents or the performance
of the obligations hereunder or thereunder; and (d) the execution and delivery of such instruments, and the taking of such other actions as the other party may reasonably require in order to carry out the intent of this Agreement; provided,
however, that neither Purchaser and its Affiliates nor Seller and its Affiliates shall be obligated to make any material disposition of or make any material change to their respective businesses, expend any material amounts, or agree to modify
the terms of any Contract, in each case to obtain any applicable consent, waiver or approval in 

  
 - 56 -

 
respect of the transactions contemplated hereby, excluding any amounts required to be expended to comply with the terms set forth in Section 5.6 hereof or the expenditure of other amounts
that are otherwise contemplated by this Agreement, including the payment of any filing fees with any applicable Governmental Entity. 
 Section 5.9 Tax Matters. 
 (a) Seller shall prepare or cause to
be prepared all Tax Returns required to be filed by the Company or any of its Subsidiaries with respect to taxable periods ending on or before the Closing Date. Seller shall cause the Company or the applicable Subsidiary thereof to file all such Tax
Returns described in the preceding sentence and shall pay or cause to be paid all Taxes shown as due on such Tax Returns. 
 (b)
Seller shall have the right to control the conduct of any audit or administrative or judicial proceeding with respect to any Taxes of, or any Tax Return required to be filed by, the Company or any of its Subsidiaries with respect to taxable periods
ending on or before the Closing Date; provided, however, that Seller shall not compromise or settle any such audit or proceeding without obtaining Purchaser’s prior written consent (which consent may not be unreasonably withheld,
conditioned or delayed) if it would reasonably be expected to have a materially adverse effect on Purchaser. 
 (c) Purchaser
and Seller shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes of the Company or any of its
Subsidiaries. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information reasonably relevant to any such audit, litigation or other proceeding and making employees available on a
mutually convenient basis to provide additional information and explanation of any material provided hereunder. Purchaser and Seller shall (i) retain all books and records with respect to Tax matters pertinent to the Company or its Subsidiaries
relating to any taxable period beginning before the Closing Date until expiration of the statute of limitations (taking into account any extensions thereof) of the respective taxable periods and (ii) give the other party reasonable written
notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, shall allow the requesting party to take possession of such books and records. 

(d) Neither Purchaser nor any of its Affiliates (including, after the Closing, the Company and its Subsidiaries) shall, without the prior
written consent of Seller (which consent may not be unreasonably withheld, conditioned or delayed), (i) make or change any Tax election affecting a taxable period ending on or before the Closing Date of Seller or any of its Affiliates
(including, before the Closing, the Company and its Subsidiaries), (ii) amend, refile or otherwise modify (or grant an extension of any applicable statute of limitations with respect to) any Tax Return prepared by Seller or any of its
Affiliates (including, before the Closing, the Company and its Subsidiaries) relating to a taxable period ending on or before the Closing Date or (iii) take any action that results in any increased Tax liability (including a reduction in a
refund) or reduction of any Tax asset of any of the Company or its Subsidiaries (or Seller or any of its Affiliates) in respect of a taxable period ending on or before the Closing Date. 

  
 - 57 -

 (e) If a refund of Taxes (to the extent not reflected on the Final Closing Balance Sheet)
(the “Refund”) is received by or credited to the account of the Company or any of its Subsidiaries in respect of any taxable period ending on or before the Closing Date, Purchaser shall cause such recipient to pay the amount of the
Refund to Seller within two (2) Business Days of the receipt thereof and shall provide written notice to Seller promptly following the receipt thereof and shall thereafter provide to Seller any additional information that it may reasonably
request in connection therewith. Notwithstanding anything herein to the contrary, Incremental Taxes arising out of a sale or other disposition of the Subject Vessels after the Closing Date which are not taken into account in determining the Net
Subject Vessel Proceeds shall be considered Taxes incurred after the Closing Date for which the Company is liable. 

Section 5.10 Letters of Credit. As soon as reasonably practicable following the request of Seller made after the date
hereof, Purchaser shall obtain and deliver to the beneficiary of each letter of credit that is issued in whole or in part for the benefit of the Company or any of its Subsidiaries as listed on Section 5.10 of the Seller Disclosure
Schedule, a substitute letter of credit to replace in all respects, to the extent it relates to the Company or any of its Subsidiaries, each such letter of credit (each, a “Substitute Letter of Credit”), with each Substitute
Letter of Credit not being effective until the Closing and having a face amount equal to the amount set forth on Section 5.10 of the Seller Disclosure Schedule and containing terms and conditions that are substantially similar to the
terms and conditions that are set forth in the letter of credit that it is intended to replace (in whole or in part) and otherwise containing terms and conditions that are reasonably acceptable to the beneficiary thereof. Prior to the Closing,
Purchaser shall use its reasonable best efforts to obtain from the beneficiary of each letter of credit to be replaced (in whole or in part) pursuant to the terms hereof and deliver to Seller a full and unconditional release, effective as of the
Closing, of each such letter of credit (or portions thereof) being so replaced and of all of the obligations of Seller or any Affiliate thereof (excluding, following the Closing, the Company and its Subsidiaries) with respect to such letter of
credit or the portion thereof being replaced pursuant to the terms hereof (which release shall be reasonably acceptable to Sellers) (each, a “Letter of Credit Release”). In the event Purchaser has not, as of the Closing, obtained
and delivered a Letter of Credit Release with respect to all of the letters of credit (or portions thereof) being replaced in accordance with the preceding sentence, Purchaser shall, and shall cause the Company and its Subsidiaries to, use
reasonable best efforts to do so following the Closing and shall indemnify and hold harmless each of Seller and its Affiliates (other than the Company and its Subsidiaries) from and against any and all Losses incurred by Seller or any of its
Affiliates (other than the Company and its Subsidiaries) arising out of or relating to such letter(s) of credit. 

Section 5.11 TECO Agreement. 
 (a) As soon as reasonably practicable following the request of Seller made after the date hereof, Purchaser shall deliver the TECO Performance Letter to Seller and Tampa Electric, which shall not be
effective until the Closing. Without limitation of any of the other terms set forth in this Agreement, including in this Section 5.11, (i) Purchaser shall make such changes to the TECO Performance Letter as Tampa Electric may reasonably
request and shall otherwise take or cause to be taken such other actions in respect of the TECO Agreement (including in respect of Purchaser’s or the Company’s (or its Subsidiaries’) obligations thereunder) as may reasonably be
requested by Seller or Tampa Electric in connection with the purchase by 

  
 - 58 -

 
Purchaser of the Interests, and (ii) Purchaser shall comply, and cause the Company and its Subsidiaries to comply, with all of the Company’s, its Subsidiary’s or Purchaser’s
respective obligations (if any) now or hereafter existing under the terms of the TECO Agreement (including without limitation any obligation of the Company or any Subsidiary thereof to maintain any insurance applicable to the Company or any
Subsidiary thereof or the business or operations thereof that is required pursuant to the terms of the TECO Agreement). 
 (b)
As soon as reasonably practicable following the request of Seller made after the date hereof, Purchaser shall obtain and deliver (or cause to be delivered) to Tampa Electric a letter of credit, substantially in the form attached hereto as Exhibit
H (subject to such changes thereto as Tampa Electric may reasonably request to be made thereto), with a face amount equal to $6,000,000, it being understood and agreed that such letter of credit shall be delivered pursuant to Section 22.1
of the TECO Agreement and shall satisfy and comply with the requirements of a “Letter of Credit” under the terms of the TECO Agreement (including in respect of the minimum credit rating of the issuer thereof as set forth in the definition
of “Letter of Credit” in the TECO Agreement) and otherwise comply with all of the requirements of the TECO Agreement, including in respect of the period of time during which such letter of credit shall remain outstanding and the expiration
date thereof (the “TECO Letter of Credit”); provided, however, that the TECO Letter of Credit shall not be effective until the Closing shall have occurred. In the event that at any time following the Closing, the TECO Letter
of Credit shall be drawn upon, then Purchaser shall cause the face amount of such letter of credit to be increased, or shall cause an additional letter of credit that complies with the terms set forth in the immediately preceding sentence and the
TECO Agreement, and that is substantially identical to the TECO Letter of Credit obtained and delivered to Tampa Electric in connection with the Closing to be delivered to Tampa Electric, such that the aggregate face amount of all letters of credit
delivered to and held by Tampa Electric (after giving effect to any draws on letters of credit previously delivered to Tampa Electric by or on behalf of Purchaser) under the TECO Agreement shall be no less than $6,000,000. 

(c) From and after the date hereof and prior to the Closing, Purchaser and Seller shall, and shall cause their respective Affiliates to,
subject (in the case of Seller and its Affiliates) to the terms set forth in the last sentence of Section 5.8, use their respective reasonable best efforts to obtain from Tampa Electric and deliver to Seller a full and unconditional release,
effective as of the Closing, of all of the obligations and liabilities of Seller and its Affiliates (other than the Company and its Subsidiaries) with respect to (i) the TECO Letter of Credit (including any obligation to increase the face
amount thereof or deliver a supplemental letter of credit), or (ii) the obligations and liabilities of the Company or any Subsidiary thereof pursuant to the TECO Agreement, including any obligation of Seller to cause the Company and its
Subsidiaries to perform their respective obligations thereunder or be liable to Tampa Electric for any breach or non-compliance by the Company or any Subsidiary thereof with the terms set forth therein (which release shall be in a form reasonably
acceptable to Seller) (the “TECO Release”). In furtherance of the foregoing, if requested by Seller or Tampa Electric, Purchaser shall (or shall cause an Affiliate thereof designated by Seller or Tampa Electric to), effective at the
Closing, agree to assume and be liable and responsible for (through the execution of a Contract containing terms and conditions that are reasonably acceptable to Seller and Tampa Electric) any and all of the obligations and liabilities of Seller
with respect to the TECO Letter of Credit (including any obligation to increase the face amount thereof or deliver a supplemental letter of credit) and 

  
 - 59 -

 
under the terms of the TECO Agreement (including any obligation of Seller to cause the Company or any Subsidiary thereof to perform their respective obligations thereunder or be liable to Tampa
Electric for any breach or non-compliance by the Company or any Subsidiary thereof with the terms set forth therein), but only to the extent that such obligations and liabilities relate to the Company or any Subsidiary thereof, and specifically
excluding any obligations or liabilities of Seller under the TECO Agreement that relate to Subsidiaries of Seller thereunder that are not the Company or any Subsidiary thereof (the obligations so assumed, the “TECO Assumed
Obligations”). In the event Purchaser and Seller have not, as of the Closing, obtained the TECO Release, (i) Purchaser shall use reasonable best efforts to do so following the Closing, including by agreeing to assume (in accordance
with the terms set forth in the immediately preceding sentence) the TECO Assumed Obligations through the execution of a Contract containing terms and conditions that are reasonably acceptable to Seller and Tampa Electric, (ii) Purchaser shall
not permit, and shall cause the Company not to permit, the TECO Agreement to be amended, supplemented, modified, renewed or extended in a manner that increases or extends, or that is reasonably likely to increase or extend, the obligations of Seller
or any Affiliate thereof thereunder, without the prior written consent of Seller, and (iii) Purchaser shall, and shall cause the Company to, indemnify and hold harmless each of Seller and its Affiliates (other than the Company) from and against
any and all Losses incurred by Seller or any of its Affiliates (other than the Company) arising out of or relating to the TECO Letter of Credit or the obligations or liabilities of the Company pursuant to the TECO Agreement, including in the event
of any Letter of Credit Default (as defined in the TECO Agreement) or in the event of any requirement of Seller to reinstate the TECO Letter of Credit pursuant to the terms of the TECO Agreement. 

Section 5.12 Support Services; Marks. 
 (a) Purchaser acknowledges that the Company and its Subsidiaries currently receive (or has received in the past) from Seller or its Affiliates certain corporate and other services and support, including
general and administrative services, audit services, legal services, human resources services, tax services, finance services, cash management services, information technology services and support and insurance and facilities-related support
(collectively, the “Support Services”). Purchaser acknowledges that, except as expressly provided in this Agreement or the Transition Services Agreement, the Support Services shall cease as of the Closing, and all agreements and
arrangements in respect thereof shall terminate as of the Closing, with no further obligation of any party thereto. 
 (b) Prior
to the Closing, Seller shall use its commercially reasonable efforts to, and shall cause its Subsidiaries (other than the Company and its Subsidiaries to) effect the assignment of the mark “UNITED BULK TERMINAL” and all related marks,
logos and domain names to the Company (including those domain names set forth on Section 5.12(b) of the Seller Disclosure Schedule), to the extent not already owned by the Company; provided that if such any such assignment has not been
effected as of the Closing, Seller shall use its commercially reasonable efforts to effect such assignment as soon as reasonably practicable following the Closing and the parties agree to use their respective commercially reasonable efforts to
cooperate and work together following the Closing in respect thereof. 

  
 - 60 -

 Section 5.13 Insurance. Purchaser acknowledges and agrees that all
insurance coverage for the Company, its Subsidiaries and the Business under policies of Seller and its Affiliates (other than the Company and its Subsidiaries) shall terminate as of the Closing, and no claims may be brought thereunder by Purchaser,
the Company or its Subsidiaries from and after the Closing under or with respect to any such insurance or the policies relating thereto; provided, however, that nothing in this Section 5.13 shall in any way affect the right of the
Company or its Subsidiaries to be covered by, and make claims under, any such policy that is an occurrence-based policy for events or circumstances occurring with respect to the Company or its Subsidiaries prior to Closing if permitted under such
policy, provided that such claims shall be at the Company’s (or its Subsidiaries’) sole cost and expense (including any applicable retentions or deductibles in connection with such claims and any fees or other costs or expenses incurred in
connection with the collection thereof); provided further, however, that in the event any occurrence-based insurer shall make such payment on behalf of the Company or any Subsidiary thereof to Seller or an Affiliate of Seller
(other than the Company or any Subsidiary thereof) in connection with such pre-Closing losses, Seller shall promptly remit such occurrence-based policy recoveries, if applicable, to the Company or the applicable Subsidiary thereof. 

Section 5.14 Notice by Seller. 
 (a) Prior to the Closing Date, Seller shall promptly provide notice to Purchaser of the occurrence of any breach of any representation or warranty of Seller set forth in Article III of this Agreement or
the occurrence of any event or circumstance that would reasonably be likely to cause or constitute a breach of any such representation or warranty had that representation or warranty been made as of the time of the occurrence of such event or
circumstance, in each case only if such breach would result in the condition to Closing set forth in Section 6.2(a) not being satisfied; provided, however, that (i) the failure to provide any such notice shall not affect the
obligations of the parties to effect the Closing if all of the conditions to Closing set forth in this Agreement shall have been satisfied or waived (assuming, for these purposes, that the failure to provide such notice had not occurred), and
(ii) no such notice will be deemed to have cured any breach of any representation or warranty or affect any right or remedy of Purchaser under this Agreement. 
 (b) Prior to the Closing Date, Seller shall promptly provide notice to Purchaser of any breach of any covenant of Seller set forth in Article V of this Agreement if such breach would result in the
condition to Closing set forth in Section 6.2(b) not being satisfied; provided, however, that (i) the failure to provide any such notice shall not affect the obligations of the parties to effect the Closing if all of the conditions
to Closing set forth in this Agreement shall have been satisfied or waived (assuming, for these purposes, that the failure to provide such notice had not occurred), and (ii) no such notice will be deemed to have cured any breach of any
representation or warranty or affect any right or remedy of Purchaser under this Agreement. 
 Section 5.15 Notice by
Purchaser. 
 (a) Prior to the Closing Date, Purchaser shall promptly provide notice to Seller of the occurrence of any
breach of any representation or warranty of Purchaser set forth in Article IV of this Agreement or the occurrence of any event or circumstance that would reasonably be likely to cause or constitute a breach of any such representation or warranty had
that representation or 

  
 - 61 -

 
warranty been made as of the time of the occurrence of such event or circumstance, in each case only if such breach would result in the condition to Closing set forth in Section 6.3(a) not
being satisfied; provided, however, that (i) the failure to provide any such notice shall not affect the obligations of the parties to effect the Closing if all of the conditions to Closing set forth in this Agreement shall have been
satisfied or waived (assuming, for these purposes, that the failure to provide such notice had not occurred), and (ii) no such notice will be deemed to have cured any breach of any representation or warranty or affect any right or remedy of
Seller under this Agreement. 
 (b) Prior to the Closing Date, Purchaser shall promptly provide notice to Seller of any breach
of any covenant of Purchaser set forth in Article V of this Agreement if such breach would result in the condition to Closing set forth in Section 6.3(b) not being satisfied; provided, however, that (i) the failure to provide any
such notice shall not affect the obligations of the parties to effect the Closing if all of the conditions to Closing set forth in this Agreement shall have been satisfied or waived (assuming, for these purposes, that the failure to provide such
notice had not occurred), and (ii) no such notice will be deemed to have cured any breach of any representation or warranty or affect any right or remedy of Seller under this Agreement. 

Section 5.16 UIS-UOS Agreement. 

(a) From and after the date hereof and until the date that is fifteen (15) days from the date hereof (or such later date as Seller
shall agree to in writing), subject to the terms and conditions set forth in this Section 5.16, Purchaser shall have the right to (i) negotiate with any third party that is a citizen of the United States pursuant to 46 U.S.C. § 50501,
eligible to own and operate vessels in the coastwise trade of the United States (a “Qualified Person”), (A) the sale to such Qualified Person of the vessels listed on Section 5.16 of the Seller Disclosure Schedule
(the “Subject Vessels”), provided that, unless Seller shall otherwise agree in writing following the date hereof, the purchase price for each Subject Vessel must at least be equal to the Fair Market Value (as defined in the
Indenture) thereof and the consideration payable by the purchaser in connection therewith must consist solely of cash in United States Dollars, and (B) the transfer to such Qualified Person of the employees of the Company or any applicable
Subsidiary thereof whose employment primarily relates to the operation of such Subject Vessels, and (ii) request that Seller cause the Company or the applicable Subsidiary thereof to enter into definitive documentation in respect of any such
sale and the transfer of such employees, and following such request, Seller shall cause the Company or the applicable Subsidiary thereof to enter into such definitive documentation; provided, however, that (1) prior to entering into any
such negotiations or having any discussions with any such third party, Purchaser shall have caused such third party to have executed and delivered to Seller a confidentiality agreement that is in form and substance reasonably satisfactory to Seller,
(2) Purchaser shall provide Seller such reasonable access to such information and documents as Seller may reasonably request in connection with the terms set forth in this Section 5.16, including access to any documents that the Company or
any Subsidiary thereof is being requested to enter into or that is otherwise being entered into in connection with the transactions contemplated by this Section 5.16, (3) in no event shall Purchaser have the right to bind the Company or
any Subsidiary thereof to any obligations or liabilities (including contractual obligations) prior to the Closing Date, and Seller shall not be required to cause the Company or any Subsidiary thereof to become bound by the terms of any Contract or
incur any such obligations or liabilities, in each case prior to the Closing 

  
 - 62 -

 
Date or that are effective prior to the Closing Date, (4) neither the Company nor any Subsidiary thereof shall be required to enter into any Contract pursuant to this Section 5.16, and
Seller shall not be required to cause the Company or any Subsidiary to enter into any Contract pursuant to this Section 5.16, unless (in each case) such Contract is reasonably acceptable to Seller, it being agreed that, unless Seller shall
otherwise determine in writing, any Contract that does not provide for a purchase price for each Subject Vessel at least equal to the Fair Market Value (as defined in the Indenture) thereof and for the payment of only cash consideration shall not be
reasonably acceptable to Seller, (5) Purchaser shall reimburse Seller and its Affiliates for any and all reasonable out-of-pocket fees, costs or expenses incurred by Seller or any Affiliate thereof in connection with the foregoing, including in
connection with any filings required to be made with any Governmental Authority in connection therewith, provided that if Seller shall request, Purchaser shall pay (on behalf of Seller or the applicable Affiliate thereof) all such out-of-pocket
fees, costs or expenses incurred by Seller or any Affiliate thereof in connection with the foregoing, and (6) Purchaser shall indemnify and hold harmless Seller and its Affiliates in respect of any and all Losses suffered by any of them in

Section 5.16, including any Losses incurred by Seller or any Affiliate thereof in respect of any claims made by the purchaser of the Subject Vessels and the employees of the Company and its Subsidiaries whose employment primarily relates to the
operation of the Subject Vessels, it being understood and agreed that, if requested by Seller, the Contract pursuant to which such Subject Vessels shall be sold or otherwise transferred and that such employees shall be transferred shall require
Purchaser (and not Seller) to agree to be responsible for and liable to any such purchaser in respect of any claims, liabilities or obligations in connection with or arising out of or relating to such sale or other transfer of such Subject Vessels
and the transfer of such employees. 
 (b) Notwithstanding the terms set forth in Section 5.16(a), if, as of immediately
prior to the Closing Date and in accordance with the terms set forth in Section 5.16(a), neither the Company nor any Subsidiary shall have (i) entered into a Contract providing for the sale to a Qualified Person of the Subject Vessels and
the related transfer of certain employees of the Company and/or its Subsidiaries as provided herein, and (ii) consummated the transactions contemplated by such Contract, then the UIS-UOS Agreement shall become effective immediately prior to the
Closing in accordance with the terms set forth therein, and Purchaser hereby agrees to the foregoing for all purposes of this Agreement and otherwise.

the sale shall remain in the Company or the Subsidiary.

to, or otherwise knowingly cooperate with, knowingly facilitate or knowingly encourage any effort or attempt by any Person to do or seek, a Third-Party Acquisition; provided, however, that, for the avoidance of doubt, nothing contained herein
shall limit, preclude or restrict the right of any Company Party to take any of the actions otherwise prohibited hereunder with respect to Seller or any Subsidiary of Seller (other than the Company or any Subsidiary thereof), provided that if any
such actions involve Seller (as opposed to Subsidiaries of Seller other than the Company and its Subsidiaries), such actions may not provide for or contemplate, directly or indirectly, a sale of the Company or its Subsidiaries in connection
therewith; provided further, however, that nothing contained herein shall limit, preclude or otherwise restrict any action of Seller or any Affiliate thereof with respect to the matters contemplated by Section 5.16.

Company or any of its Subsidiaries, Seller will use its commercially reasonable efforts to ensure that all data and Records related to the operations of the Company and its Subsidiaries, including financial and accounting Records, studies, reports,
personnel Records, correspondence and other similar documents and Records, are transferred into the possession of the Company or its applicable Subsidiary as of the Closing Date; provided, however, to the extent such Records and other such
data have not been so transferred into the possession of the Company and its Subsidiaries by the Closing Date, Seller will use its commercially reasonable efforts to transfer such Records and other such data to the Company and its Subsidiaries as
soon as reasonably practicable following the Closing Date. Without limiting the foregoing, Seller shall use its commercially reasonably efforts to preserve such Records and data, consistent with past practice, until such time as they are transferred
to into the possession of the Company and its Subsidiaries as contemplated by the preceding sentence. For the avoidance of doubt, if any such data or Records relate to businesses of Seller and its Subsidiaries (other than the Company and its
Subsidiaries), Seller or any such Subsidiary shall be entitled to continue to use and retain the same, without limitation of the terms set forth in this Section 5.18. After the Closing, Purchaser or the Company may retain (at the sole cost and
expense of Purchaser or the Company) an independent certified public accountant to audit the 2011 operations and financial and accounting Records of the Company, and Seller agrees to reasonably cooperate with the such accountant in the performance
and completion of such audit, provided that Purchaser or the Company (as the case may be), shall promptly reimburse Seller for any out-of-pocket costs and expenses reasonably incurred by Seller in providing such cooperation. After the Closing,
Purchaser shall, and shall cause its Affiliates (including the Company following the Closing) to, reasonably cooperate with Seller or any Affiliate thereof in connection with Seller’s or such Affiliate’s preparation of tax and other
financial reports of Seller or such Affiliate in respect of the Company and any Subsidiary thereof or the consummation of the transactions contemplated hereby, provided that Seller shall promptly reimburse Purchaser or its Affiliates (as the case

has failed to consummate the Closing when required in accordance with this Agreement, (B) Purchaser has provided Seller with written notice of such failure and (C) Seller has failed to consummate the Closing within two (2) Business
Days of receipt of such notice described in the immediately preceding clause (B), or (ii) there shall have been (x) a breach of any of the representations and warranties of Seller set forth in Article III of this Agreement (and such breach
has not been waived by Purchaser), which breach would cause the condition set forth in Section 6.2(a) not to be satisfied, or (y) a breach of any of the covenants or agreements of Seller set forth in this Agreement (and such breach has not
been waived by Purchaser), which breach would cause the condition set forth in Section 6.2(b) not to be satisfied, but only (in the case of clauses (x) and (y) immediately above), if such breach is not cured on or before the earlier
to occur of (1) thirty (30) days after receipt by Seller of written notice thereof from Purchaser, and (2) the Outside Date; and 
 (f) by Seller if (i) (A) Purchaser has failed to consummate the Closing when required in accordance with this Agreement, (B) Seller has provided Purchaser with written notice of such
failure and (C) Purchaser has failed to consummate the Closing within two (2) Business Days of receipt of such notice described in the immediately preceding clause (B), or (ii) there shall have

  
 - 67 -

 
been (x) a breach of any of the representations and warranties of Purchaser set forth in Article IV of this Agreement (and such breach has not been waived by Seller), which breach would
cause the condition set forth in Section 6.3(a) not to be satisfied, or (y) a breach of any of the covenants or agreements on the part of Purchaser set forth in this Agreement (and such breach has not been waived by Seller), which breach
would cause the condition set forth in Section 6.3(b) not to be satisfied, but only (in the case of clauses (x) and (y) immediately above), if such breach is not cured on or before the earlier to occur of (1) thirty
(30) days after receipt by Purchaser of written notice thereof from Seller, and (2) the Outside Date. 

Section 7.2 Effect of Termination. 
 (a) In the event of the termination of this Agreement by any party pursuant to Section 7.1 (other than Section 7.1(a)), written notice thereof shall forthwith be given by the terminating party
to the other party, and this Agreement shall thereupon terminate and become void and have no effect, the transactions contemplated hereby shall be abandoned without further action by the parties and there shall be no liability or obligation on the
part of Seller or Purchaser to any other party hereto; provided, however, that (i) Section 5.3, Section 5.4, Section 5.16 (but only with respect to clauses (5) and (6) of the proviso of such Section), this
Section 7.2 and Article IX and the Confidentiality Agreement shall expressly survive the termination of this Agreement, (ii) termination of this Agreement shall have no effect on the Parent Guarantee, which shall remain in full force and
effect with respect to Purchaser’s obligations and liabilities hereunder following the termination of this Agreement, and (iii) no party hereto shall be relieved of any liability or obligation arising from, out of or in connection with any
willful breach of this Agreement by such party prior to the time of such termination. 
 (b) For the avoidance of doubt and
without limiting Seller’s rights under any other provision of this Agreement (including Seller’s right to specific performance pursuant to Section 9.14) or pursuant to the Parent Guarantee, for all purposes of this Agreement, the
failure of Purchaser to consummate the Closing for any reason when required pursuant to the terms of this Agreement and/or to make the payments to Seller or any other Person pursuant to Article II for any reason when required pursuant to the terms
of this Agreement shall, in each case, be a willful breach of this Agreement by Purchaser that (i) is not capable of being cured after the expiration of the period referred to in Section 7.1(f)(i)(C), (ii) has prevented the
consummation of the transactions contemplated hereby, and (iii) gives rise to Seller’s termination right pursuant to Section 7.1(f), which in turn shall give rise to a claim by, and entitlement of, Seller for damages from Purchaser,
including damages calculated based on the Closing Consideration payable to Seller pursuant to the terms hereof if the Closing had occurred (assuming, for these purposes, that all proceeds that would have been deposited into the Escrow Account at the
Closing were paid to Seller and that no adjustment to the Base Purchase Price is made pursuant to the applicable terms set forth in Article II). 
 (c) For the avoidance of doubt and without limiting Purchaser’s rights under any other provision of this Agreement (including Purchaser’s right to specific performance pursuant to
Section 9.14), for all purposes of this Agreement, the failure of Seller to consummate the Closing for any reason when required pursuant to the terms of this Agreement shall be a willful breach of this Agreement by Seller that (i) is not
capable of being cured after the expiration of the period referred to in Section 7.1(e)(i)(C), (ii) has prevented the consummation of the 

  
 - 68 -

 
transactions contemplated hereby, and (iii) gives rise to Purchaser’s termination right pursuant to Section 7.1(e), which in turn shall give rise to a claim by, and entitlement of,
Purchaser for damages from Seller incurred as a result thereof as determined by the parties or, failing such agreement, by a final and non-appealable judgment of a court of competent jurisdiction. 

(d) For purposes hereof, “willful breach” shall mean a breach that is a consequence of an omission by, or act undertaken by or
caused by, the breaching party with the knowledge that the omission or taking or causing of such act would, or would reasonably be expected to, cause a breach of this Agreement. 

Section 7.3 Amendment. This Agreement may be amended or modified only by a written agreement executed and delivered by
duly authorized officers of the parties hereto. This Agreement may not be modified or amended except as provided in the immediately preceding sentence and any purported amendment effected in a manner which does not comply with this Section 7.3
shall be void. 
 Section 7.4 Extension; Waiver. At any time prior to the Closing, Seller may (a) extend
the time for the performance of any of the obligations or other acts of Purchaser contained herein, (b) waive any inaccuracies in the representations and warranties of Purchaser contained herein or in any document, certificate or writing
delivered by Purchaser pursuant hereto, or (c) waive compliance by Purchaser with any of the agreements or conditions contained herein. At any time prior to the Closing, Purchaser may (i) extend the time for the performance of any of the
obligations or other acts of Seller contained herein, (ii) waive any inaccuracies in the representations and warranties of Seller contained herein or in any document, certificate or writing delivered by Seller pursuant hereto, or
(iii) waive compliance by Seller with any of the agreements or conditions contained herein. Any agreement on the part of either party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on
behalf of such party. Except as otherwise expressly set forth in this Agreement, the failure of any party to assert any of its rights hereunder shall not constitute a waiver of such rights. 

ARTICLE VIII 
 INDEMNIFICATION 
 Section 8.1 Survival of Representations,
Warranties and Covenants. The representations and warranties of Seller contained in Article III or in any certificate delivered by Seller pursuant to Section 6.2(d) shall survive the Closing until the twelve (12) month anniversary
of the Closing Date (the “Release Date”). The representations and warranties of Purchaser contained in Article IV or in any certificate delivered by Purchaser pursuant to Section 6.3(c) shall survive the Closing until the
Release Date. The covenants and agreements contained in this Agreement shall terminate on the Closing Date unless a specific covenant or agreement contained in this Agreement requires performance after the Closing Date, in which case such covenant
or agreement shall survive for a period of ninety (90) days following the date on which the performance of such covenant or agreement is required to be completed. Notwithstanding anything contained herein to the contrary, the parties hereto
hereby acknowledge and agree that any bona fide claim (and only such bona fide claim, but not the related representations, warranties, covenants or agreements) for indemnification in respect of any breach of any

  
 - 69 -

 
representation, warranty, covenant or agreement contained herein that is made in writing in accordance with the terms of this Article VIII on or prior to the Release Date (or if any such covenant
or agreement shall, in accordance with the terms of this Section 8.1, survive after the Release Date, until such time as any such covenant or agreement shall terminate as provided in this Section 8.1) shall survive the Release Date (or, if
applicable, such later time) until the final resolution thereof. 
 Section 8.2 General Indemnification.

 (a) Subject to the other provisions of this Article VIII, from and after the Closing, Purchaser and its Affiliates,
including, following the Closing, the Company and its Subsidiaries (each, a “Purchaser Indemnitee”), shall be indemnified and held harmless solely out of the Escrow Amount from any Losses suffered or paid by any Purchaser Indemnitee
as a result of (i) any breach of any representation or warranty made by Seller in Article III or in the certificate delivered by Seller pursuant to Section 6.2(d), or (ii) any breach by Seller of any of the covenants or agreements
made by Seller in this Agreement. 
 (b) Subject to the other provisions of this Article VIII, from and after the Closing,
Purchaser shall, and shall after the Closing, cause the Company to, indemnify and hold harmless Seller and its Affiliates (each, a “Seller Indemnitee”) from any Losses suffered or paid by any Seller Indemnitee as a result of
(i) any breach of any representation or warranty made by Purchaser in Article IV or in the certificate delivered by Purchaser pursuant to Section 6.3(c), (ii) any breach by Purchaser of any of the covenants or agreements made by
Purchaser in this Agreement, or (iii) any claim or Action brought or threatened to be brought against any Seller Indemnitee at any time on or after the Closing Date relating to actions taken by Purchaser or any Affiliate thereof, including the
Company or its Subsidiaries, on or after the Closing. 
 Section 8.3 Third Party Claims. 

(a) If a claim, action, suit or proceeding by a Person who is not a party hereto or an Affiliate thereof (a “Third Party
Claim”) is made against any Person entitled to indemnification pursuant to Section 8.2 (an “Indemnified Party”), and if such Person intends to seek indemnity with respect thereto under this Article VIII, such
Indemnified Party shall promptly give written notice setting forth in reasonable detail the allegations set forth in such Third Party Claim (“Notice of Claim”) to the party hereto obligated to indemnify such Indemnified Party (such
notified party, the “Responsible Party”); provided, however, that the failure to give such Notice of Claim shall not relieve the Responsible Party of its obligations hereunder, except to the extent that the Responsible
Party is actually prejudiced thereby. The Responsible Party shall have thirty (30) days after receipt of such notice to assume the conduct and control, at the expense of the Responsible Party, of the settlement or defense thereof, and the
Indemnified Party shall cooperate with the Responsible Party in connection therewith; provided, however, that the Responsible Party shall permit the Indemnified Party to participate in such settlement or defense through counsel chosen
by such Indemnified Party (the fees and expenses of such counsel shall be borne by such Indemnified Party). Any such assumption of the conduct and control of the settlement or defense shall be deemed to be an admission by the Responsible Party that
the Third Party Claim is within the scope of the Responsible Party’s indemnification obligations hereunder and shall be deemed an assumption of liability and Losses by the Responsible Party with respect

  
 - 70 -

 
to such Third Party Claim. If the Responsible Party elects not to assume the conduct and control of the settlement or defense of such Third Party Claim, then the Indemnified Party shall
(i) permit the Responsible Party to participate in such settlement or defense through counsel chosen by such Responsible Party (the fees and expenses of such counsel shall be borne by such Responsible Party), and (ii) otherwise defend such
claim diligently, in good faith and in a commercially reasonable manner. Notwithstanding anything in this Agreement to the contrary, whether or not the Responsible Party shall have assumed the conduct or control of the defense or settlement of a
Third Party Claim, no Indemnified Party shall admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without the prior written consent of the Responsible Party, such consent not to be unreasonably withheld,
delayed or conditioned. Notwithstanding any right of the Responsible Party to assume the conduct and control of the settlement and defense of any Third Party Claim hereunder, the Responsible Party shall not settle any Third Party Claim, consent to
the entry of any judgment of such Third Party Claim or otherwise resolve such Third Party Claim without the prior written consent of the Indemnified Party, such consent not to be unreasonably withheld, delayed or conditioned, unless the terms of
such settlement, judgment or other resolution involves solely the payment of monetary damages that are subject to indemnification pursuant to the terms set forth in this Article VIII; provided, however, that if the Indemnified Party
shall not consent to any settlement, compromise or other resolution proposed by the Responsible Party, then the Responsible Party’s indemnification obligation (if any) pursuant to this Article VIII with respect to the Third Party Claim subject
thereto shall in no event exceed the amount that would be required to be paid in such proposed settlement, compromise or other resolution of such Third Party Claim. 
 (b) All of the parties hereto shall reasonably cooperate in the defense or prosecution of any Third Party Claim in respect of which indemnity may be sought hereunder and each of Purchaser and Seller (or a
duly authorized representative of such party) shall (and shall cause the Company and its Subsidiaries to) furnish such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials and appeals, as may be
reasonably requested in connection therewith; provided, however, that (i) at the request of any party disclosing confidential information in connection with such cooperation, the parties shall enter into a mutually agreeable
confidentiality agreement for such purpose, and (ii) no Person shall be required to disclose information if the disclosure thereof would be reasonably likely to result in the loss of the attorney-client privilege. 

Section 8.4 Limitations on Indemnification. The rights of Purchaser Indemnitees and Seller Indemnitees to
indemnification pursuant to the provisions of this Article VIII are subject to the following limitations: 
 (a) the Purchaser
Indemnitees shall not be entitled to recover any Losses pursuant to Section 8.2(a)(i) until the total amount of Losses which the Purchaser Indemnitees would be entitled to recover under Section 8.2(a)(i) with respect to any and all claims
for indemnification thereunder, but for this Section 8.4(a), exceeds $2,150,000 (the “Deductible”), and once the Deductible has been exceeded, the Purchaser Indemnitees shall only be entitled to recover Losses in excess of the
Deductible; provided, however, that the Deductible shall not apply to Losses suffered or paid by any Purchaser Indemnitee as a result of the breach of any representation or warranty made by Seller in Section 3.2, Section 3.3,
Section 3.5(a), Section 3.5(c), Section 3.12 or Section 3.21, it being agreed that in the case of a breach of any such representation or 

  
 - 71 -

 
warranty, the applicable Purchaser Indemnitee shall, subject to the other limitations set forth in this Article VIII, be entitled to be indemnified and held harmless from the first dollar of such
Losses; 
 (b) the Seller Indemnitees shall not be entitled to recover any Losses pursuant to Section 8.2(b)(i) until the
total amount of Losses which the Seller Indemnitees would be entitled to recover under Section 8.2(b)(i) with respect to any and all claims for indemnification thereunder, but for this Section 8.4(b), exceeds the Deductible, and once the
Deductible has been exceeded, the Seller Indemnitees shall only be entitled to recover Losses in excess of the Deductible; provided, however, that the Deductible shall not apply to Losses suffered or paid by any Seller Indemnitee as a result
of the breach of any representation or warranty made by Purchaser in Section 4.2 or Section 4.8, it being agreed that in the case of a breach of any such representation or warranty, the applicable Seller Indemnitee shall, subject to the
other limitations set forth in this Article VIII, be entitled to be indemnified and held harmless from the first dollar of such Losses; 
 (c) neither the Purchaser Indemnitees nor Seller Indemnitees shall be entitled to recover for any particular Loss (including any series of related Losses) pursuant to Section 8.2(a)(i) or
Section 8.2(b)(i), respectively, unless such Loss (including any series of related Losses) equals or exceeds $25,000, and any such Loss (including any series of related Losses) below such threshold shall not be counted for purposes of
determining whether the Deductible has been exceeded, provided that if such Loss (including any series of related Losses) exceeds such threshold then the applicable Purchaser Indemnitees or the Seller Indemnitees, as the case may be, shall be
entitled to recover the full amount of such Loss (including any series of related Losses), subject to (and limited by) the other terms set forth in this Article VIII; 
 (d) the sole and exclusive source of recovery in respect of any indemnification claim made by any Purchaser Indemnitee pursuant to this Article VIII shall be the Escrow Amount, and in no event shall
(i) Seller or any Affiliate thereof or any other Person have any direct liability or obligation in respect of any such indemnification claim, or (ii) the Purchaser Indemnitees be entitled to recover any Losses in respect of any
indemnification claim made pursuant to this Article VIII from any source other than the Escrow Account or in an aggregate amount in excess of the Escrow Amount on deposit in the Escrow Account as of any applicable date of determination, it being
agreed that on the date (if any) that the Escrow Amount is reduced to zero (0) for any reason (including due to the release of the Escrow Amount from the Escrow Account in accordance with the terms of the Escrow Agreement), the Purchaser
Indemnitees shall have no further rights to indemnification pursuant to this Article VIII; provided, however, that Seller shall have direct liability to Purchaser over and above the Escrow Amount in respect of any indemnification claim
arising as a result of the intentional fraud of Seller, as determined in a final and non-appealable judgment of a court of competent jurisdiction, it being agreed that in no event (including pursuant to the terms of this proviso) shall the liability
of Seller in respect of any indemnification claim exceed an amount equal to the cash consideration actually paid to and received by Seller hereunder; 
 (e) notwithstanding anything to the contrary contained in this Agreement or otherwise, the Purchaser Indemnitees shall not be entitled to be indemnified or held harmless under this Agreement (including
pursuant to a claim of breach of representation or warranty) for 

  
 - 72 -

 
any Taxes (or Losses relating to Taxes) (i) incurred in any tax period other than any tax period ending on or before the Closing Date, (ii) attributable or relating to transactions
outside of the ordinary course of business that occur on the Closing Date after the Closing and not contemplated by this Agreement or to actions related to debt incurred in connection with the transactions contemplated by this Agreement,
(iii) which are Transfer Taxes for which Purchaser is responsible pursuant to Section 9.4, or (iv) for the existence or non-existence of any Tax attribute; 
 (f) the maximum Losses indemnifiable pursuant to Section 8.2(b) shall be an amount equal to $12,900,000, except in the case of a breach of any of the covenants set forth in Sections 5.10, 5.11 and
5.16, with respect to which the limitation on liability set forth in this clause (f) shall not apply; 
 (g) the amount of
any and all Losses shall be determined net of (i) any amounts recovered or reasonably expected to be recovered by the Purchaser Indemnitees or Seller Indemnitees, as applicable, under insurance policies or from other collateral sources (such as
contractual indemnities of any Person which are contained outside of this Agreement) with respect to such Losses, and (ii) any Tax benefits realizable with respect to such Losses; 

(h) the Purchaser Indemnitees shall not be entitled to indemnification pursuant to this Article VIII for any Loss to the extent that
(i) such Loss was taken into account in the determination of the Closing Consideration pursuant to Section 2.3, including in respect of any post-Closing adjustment thereto, or (ii) the Purchaser Indemnitees could have, with
commercially reasonable efforts, mitigated or prevented such Loss; and 
 (i) in any case where a Purchaser Indemnitee recovers,
under insurance policies or from other collateral sources, any amount in respect of a matter for which such Purchaser Indemnitee was indemnified pursuant to this Article VIII, such Purchaser Indemnitee shall promptly pay over to the Escrow Agent for
re-inclusion in the Escrow Account the amount so recovered (after deducting therefrom the amount of any reasonable out-of-pocket, third-party expenses incurred by such Purchaser Indemnitee in procuring such recovery), but not in excess of the sum of
(A) any amount previously so paid out of the Escrow Amount to or on behalf of such Purchaser Indemnitee in respect of such matter and (B) any amount expended by Seller or any Seller Indemnitee in pursuing or defending any claim arising out
of such matter; provided, however, that if such recovery is made after the Release Date, such amounts shall be paid directly to Seller; provided further, however, that if, as of the Release Date, there shall be claims
pending against the Escrow Amount, then only the amount that is so recovered that is in excess of the aggregate amount of all such pending claims shall be paid to Seller and the balance shall promptly paid over to the Escrow Agent for re-inclusion
in the Escrow Account in accordance with the terms set forth herein. 
 Section 8.5 Treatment of Indemnity
Payments. All payments made out of the Escrow Amount to or for the benefit of Purchaser Indemnitees pursuant to this Article VIII shall be treated as adjustments to the Closing Consideration for tax purposes, unless otherwise required by
Law, and such agreed treatment shall govern for purposes of this Agreement. 

  
 - 73 -

 Section 8.6 Exclusive Remedy. Without limiting any rights under the
Parent Guarantee, except for the right of a party hereto to pursue specific performance pursuant to Section 9.14 (and without limitation of any such right), and subject to and without limitation of the rights of the parties pursuant to Article
II, from and after the Closing the rights to indemnification (if any) set forth in this Article VIII shall be the sole and exclusive remedy of the parties in respect of any representation, warranty, covenant or agreement set forth in this Agreement
(including in respect of any breach thereof) or otherwise relating to this Agreement or the transactions contemplated hereby or any other matter relating to any of the Company and its Subsidiaries prior to the Closing, the operation of their
respective businesses prior to the Closing, or any other transaction or state of facts involving the Company and its Subsidiaries prior to the Closing (including any common law or statutory rights or remedies for environmental, health, or safety
matters), in each case regardless of the legal theory under which such liability or obligation may be sought to be imposed, whether sounding in contract or tort, or whether at law or in equity, or otherwise, and the Purchaser Indemnitees and Seller
Indemnitees shall have no other remedy or recourse with respect to any of the foregoing other than pursuant to, and subject to the terms and conditions of, this Article VIII. The parties hereto acknowledge and agree that they may not avoid such
limitation on liability by (a) seeking damages for breach of contract, tort or pursuant to any other theory of liability, all of which are hereby waived, or (b) asserting or threatening any claim against any Person that is not a party
hereto (or a successor to a party hereto) for breaches of the representations, warranties, covenants and agreements contained in this Agreement. The parties agree that the provisions in this Agreement relating to indemnification, and the limits
imposed on the parties’ rights and remedies with respect to this Agreement and the transactions contemplated hereby (including in Section 8.1, Section 8.2, Section 8.4 and this Section 8.6) were specifically bargained for
between sophisticated parties and were specifically taken into account in the determination of the amounts to be paid to Seller hereunder.

Section 9.5 Construction; Interpretation. The term “this Agreement” means this Membership Interest Purchase
Agreement together with the Seller Disclosure Schedule and exhibits hereto, as the same may from time to time be amended, modified, supplemented or restated in accordance with the terms hereof. The headings contained in this Agreement are

all provisions of this Agreement shall be construed according to their fair meaning and not strictly for or against any party. Unless otherwise indicated to the contrary herein by the context or use thereof: (i) the words,
“herein,” “hereto,” “hereof” and words of similar import refer to this Agreement as a whole, including the Schedules and exhibits, and not to any particular section, subsection, paragraph,

 Section 9.6 Exhibits and Schedules. Any item disclosed in the Seller
Disclosure Schedule referenced by a particular section in this Agreement or the Seller Disclosure Schedule shall be deemed to have been disclosed with respect to every other section in this Agreement and the Seller Disclosure
Schedule if the relevance of such disclosure to such other section is reasonably apparent. The specification of any dollar amount in the representations or warranties contained in this Agreement or the inclusion of any specific item in the
Seller Disclosure Schedule is not intended to imply that such amounts, or higher or lower amounts or the items so included or other items, are or are not material, and no party hereto shall use the fact of the setting of such amounts or the
inclusion of any such item in any dispute or controversy as to whether any obligation, items or matter not described herein or included in a Schedule is or is not material for purposes of this Agreement.

hereto and its successors and permitted assigns and, except (a) as provided in Section 5.7 and Article VIII, and (b) with respect to Willkie Farr & Gallagher LLP and The Miller Law Firm, PLLC, the rights set forth in
Section 9.15, nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement. Without limitation of the
foregoing, the representations and warranties set forth in Articles III and IV and (except as otherwise expressly set forth in the immediately preceding sentence) the covenants and agreements set forth in this Agreement have been made solely for the
benefit of the parties to this Agreement and (i) may be intended not as statements of fact, but rather as a way of allocating the risk to one of the parties if those statements prove to be inaccurate, (ii) have been qualified by reference
to the Seller Disclosure Schedule, which contains certain disclosures that are not reflected in the text of this Agreement, and (iii) may apply standards of materiality in a way that is different from what may be viewed as material by
members of, or other investors in (including investors that own any debt securities issued by Seller, the Company or their respective Affiliates), Seller, the Company or their respective Affiliates, and therefore should not be relied upon by any
Person that is not a party to this Agreement.

this Agreement is invalid, illegal or unenforceable, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party hereto.

 Section 9.11 No Recourse. Notwithstanding anything that may be expressed
or implied in this Agreement, Purchaser agrees and acknowledges that no recourse under this Agreement or any other Transaction Document shall be had against any current or future director, officer, employee, managing member or member of Seller or of
any Affiliates or assignees thereof, as such, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable Law, it being expressly agreed and acknowledged that no
personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any current or future director, officer, employee, managing member or member of Seller or any current or future director, officer, employee, managing member or
member of any Affiliate of Seller or assignee thereof, as such, for any obligation of Seller under this Agreement or any other Transaction Document for any claim based on, in respect of or by reason of such obligations or their creation. 

Section 9.12 WAIVER OF JURY TRIAL. EACH PARTY TO THIS AGREEMENT HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW,
ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, CONTROVERSY, DEMAND, ACTION, OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR (II) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES IN RESPECT OF THIS AGREEMENT OR
ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. EACH PARTY HEREBY FURTHER AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF
ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES MAY FILE A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. 

Section 9.13 Jurisdiction and Venue. Each of the parties hereto (a) submits to the exclusive jurisdiction of any
state or federal court sitting in Delaware, in any action or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby, (b) agrees that all claims in respect of such action or proceeding shall be heard and
determined exclusively in any such court, and (c) agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court. Each of the parties hereto waives any defense of inconvenient forum to the
maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of the other party with respect thereto. Each party hereto agrees that service of summons and complaint or any other process that
might be served in any action or proceeding may be made on such party by sending or delivering a copy of the process to the party to be served at the address of the party and in the manner provided for the giving of notices in Section 9.2.
Nothing in this Section 9.13, however, shall affect the right of any party to serve legal process in any other manner permitted by Law. Each party hereto agrees that a final, non-appealable judgment in any action or proceeding so brought shall
be conclusive and may be enforced by suit on the judgment or in any other manner provided by Law. 
 Section 9.14
Specific Performance. The parties hereby agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any provision of this Agreement (including failing to
take such actions as are 

  
 - 78 -

 
required of it hereunder to consummate the transactions contemplated hereby) is not performed in accordance with its specific terms or is otherwise breached or threatened to be breached.
Accordingly, the parties agree that, prior to the valid termination of this Agreement in accordance with Section 7.1, each party shall be entitled to an injunction or injunctions, or any other appropriate form of specific performance or
equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction in accordance with Section 9.13, this being in addition to any other remedy to
which they are entitled under the terms of this Agreement at law or in equity (and each party hereby waives any requirement for the securing or posting of any bond or other collateral in connection with such remedy). Each of the parties agrees that
it will not oppose the granting of an injunction, specific performance and other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other parties have an adequate remedy at law or an award of
specific performance is not an appropriate remedy for any reason at law or equity. 
 Section 9.15 Waiver of
Conflicts. Recognizing that Willkie Farr & Gallagher LLP and The Miller Law Firm, PLLC have acted as legal counsel to Seller, certain of Seller’s Affiliates and direct and indirect equity holders (including Greenstreet Equity
Partners, LLC and its Affiliates), and the Company and its Subsidiaries prior to the Closing, and that Willkie Farr & Gallagher LLP and The Miller Law Firm, PLLC intend to act as legal counsel to Seller and certain of Seller’s
Affiliates and direct and indirect equity holders (including Greenstreet Equity Partners, LLC and its Affiliates) after the Closing, Purchaser hereby waives, on its own behalf and agrees to cause its Affiliates (including, following the Closing, the
Company and its Subsidiaries) to waive, any conflicts that may arise in connection with Willkie Farr & Gallagher LLP and/or The Miller Law Firm, PLLC representing any of Seller and/or Seller’s Affiliates or direct and indirect equity
holders (including Greenstreet Equity Partners, LLC and its Affiliates) after the Closing as such representation may relate to Purchaser, the Company and its Subsidiaries or the transactions contemplated herein or the other Transaction Documents. In
addition, all communications involving attorney-client confidences between any of Seller or Seller’s Affiliates or direct or indirect equity holders (including Greenstreet Equity Partners, LLC and its Affiliates) in the course of the
negotiation, documentation and consummation of the transactions contemplated hereby and by the other Transaction Documents shall be deemed to be attorney-client confidences that belong solely to Seller and such Affiliates and direct and indirect
equity holders (and not Purchaser or its Affiliates (including, following the Closing, the Company and/or its Subsidiaries)). Accordingly, neither Purchaser nor, following the Closing, the Company and/or its Subsidiaries shall have access to any
such communications, or to the files of Willkie Farr & Gallagher LLP or The Miller Law Firm, PLLC relating to such engagement, whether or not the Closing shall have occurred. Without limiting the generality of the foregoing, upon and after
the Closing, (i) Seller and its applicable Affiliates and direct and indirect equity holders (including Greenstreet Equity Partners, LLC and its Affiliates) shall be the sole holders of the attorney-client privilege with respect to such
engagement, and none of Purchaser or its Affiliates (including, following the Closing, the Company and/or its Subsidiaries) shall be a holder thereof, (ii) to the extent that files of Willkie Farr & Gallagher LLP or The Miller Law
Firm, PLLC in respect of such engagement constitute property of the client, only Seller and/or Seller’s applicable Affiliates and direct and indirect equity holders (including Greenstreet Equity Partners, LLC and its Affiliates) shall hold such
property rights and (iii) Willkie Farr & Gallagher LLP and The Miller Law Firm, PLLC shall have no duty whatsoever to reveal or disclose any such attorney-client communications or files to Purchaser or

  
 - 79 -

 
its Affiliates (including, following the Closing, the Company and/or its Subsidiaries) by reason of any attorney-client relationship between Willkie Farr & Gallagher LLP or The Miller
Law Firm, PLLC and Seller or the Company or any Subsidiary thereof or otherwise.

Essence. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.
