and the Vessels and ATB Unit were constructed in accordance with the Contract Documents and all applicable requirements of the Regulatory Authorities. During any trials, the ATB Unit will be inspected by the Regulatory Authorities, the Builder and
the Owner. 
 4.4 The Builder and the Owner acknowledge that the ATB Unit’s Dredging System can only be effectively tested by loading
and unloading a quantity of material into and out of the ATB Unit’s hopper (the “System Tests”), and that the System Tests during Sea Trials are essential to demonstrate that the Work and all the Vessels’ machinery, equipment and
systems operate in accordance with the Contract Documents. The Owner shall provide at its cost the operating crew for performance of the System Tests and all necessary permits required to conduct the System Tests. In the event that the System Tests
cannot be completed at the time of the Sea Trials or within seventy-two hours of the completion of Sea Trials and the cause for such lack of completion of the System Tests is not due to any breach of the Contract by the Builder or any act or
omission of the Builder, the Owner shall take Delivery of the ATB Unit provided that all other requirements for Delivery are completed, and the Owner shall withhold $500,000.00 from the Delivery Payment (the “Retained Amount”) until such
time as the System Tests have been satisfactorily completed. The Owner and the Builder shall perform the System Tests. The Owner shall notify the Builder in writing, and in the same form as Exhibit P, of any defects in the Dredging System within
fifteen (15) Working Days of the performance of the System Tests. In the event the Owner has not notified the Builder of a defect in the Dredging System within such time, the Owner shall pay the Retained Amount to the Builder. Any defects in
the Dredging System attributable to Builder discovered during the System Tests and timely notified to the Builder shall be remedied by the Builder in accordance with the provisions of this Article 4, after which the Owner shall pay the Retained
Amount to the Builder less the following, as applicable: 
 (a) deductions from the early completion premium or additions to the late
completion liquidated damages for each Day the ATB Unit is out of service to effect repairs to the Dredging System, at the applicable rate specified in Article 8; 

(b) deductions from the early completion premium or additions to the late completion liquidated damages for each Day the System Tests exceed
three (3) Days of testing (or a length of time as otherwise agreed by the parties), at the applicable rate specified in Article 8; and 

(c) any costs to the Owner reimbursable under Article 11.2 of this Agreement. 

4.5 The Builder acknowledges that the Vessels are being built as part of a dual mode articulated tug/barge trailing suction hopper dredge and
that the construction and operation of each component part so as to operate as one fully integrated dual mode articulated tug/barge trailing suction hopper dredge is the object of the Contract. Acceptance by and Delivery to the Owner shall be
subject to and conditioned upon the successful Sea Trials, Dock Trial and System Tests of the ATB Unit and not its component parts.

 If the Owner is not satisfied with the Work, the Owner will promptly, and in any event within
five (5) Working Days after conclusion of the Dock Trials and/or Sea Trials (as applicable), notify the Builder in writing, setting forth the nature and character of the problem in sufficient detail to fully apprise the Builder of same in the
form attached as Exhibit P. The Builder shall work as expeditiously as possible to resolve the problem so that the ATB Unit conforms with the Contract Documents. When the trials and tests are complete and the problems, if any, are resolved to the
Owner’s reasonable satisfaction, Delivery of the ATB Unit will be deemed achieved, subject to the Builder’s compliance with Article 5.6. 

If a complaint regarding the Work under this Article 4 cannot be resolved and settled by the parties, then such complaint shall be settled in
the manner provided for in Article 25 of this Agreement. During the pendency of such dispute and at the direction of Owner, Builder will proceed to resolve the Owner’s complaint on a time and material basis as defined in Article 9.7. If it
is determined that the Work directed by Owner was not required by the Contract Documents, then Owner will pay Builder for such Work on a time and material basis as defined in Article 9.7 and the Delivery Date shall be adjusted by the number of Days
the Work directed by Owner took to complete. The party who does not prevail in this dispute will also be required to pay any costs of additional testing and Dock Trials, Sea Trials or Systems Test. If it is determined that the Work was required
by the Contract Documents, then the Work shall be deemed to have been part of the Contract Price and no additional amount shall be due to the Builder and the Builder shall be deemed to have been required to correct the Work, subject to liquidated
damages for delays provided in this Agreement and, at Builder’s sole cost and expense, to such additional testing and Dock Trials, Sea Trials or System Tests as may be required in order to complete and satisfactorily test the Work in accordance
with the Contract Documents. 
 4.6 The Owner shall provide to the Builder a Shipyard Contract Deficiency Report in the form of Exhibit P as
a means to communicate items that need to be addressed by the Builder before Delivery. 
 4.7 The Builder shall deliver the ATB Unit to the
Owner in accordance with the Contract on or before the Delivery Date free and clear of liens and encumbrances and with Lien Release(s) in the forms of Exhibits G-1 and G-2, as required by Article 5.6, provided the Builder has been paid all amounts
due under this Agreement. 
 4.8 Delivery shall be made safely afloat at the Builder’s shipyard in Panama City, Florida or at a location
mutually agreed by the Owner and the Builder. If Delivery is made at an offshore location, the costs of such offshore delivery will be the subject of a Change Order for the account of the Owner; provided, however, that if the ATB Unit is delivered
offshore immediately after the Sea Trials have been successfully completed, no Change Order or additional monies shall be due by the Owner.

 ARTICLE 5 – PAYMENT 

5.1 The Work shall be performed by the Builder in consideration of the Owner’s payment of the Contract Price for each Vessel in the
manner set forth in Exhibit A of this Agreement and Change Orders. 
 5.2 The Owner agrees to pay the Contract Price of each Vessel to the
Builder in Interim Installment Payments which shall correlate to the Milestone Schedule as set forth in Exhibit Q. In the event that the Owner shall fail to pay the first Interim Installment Payment as provided by Exhibit Q due to no fault of the
Builder, the Builder shall have the right, at its sole discretion, to (i) cancel this Agreement, in which event the Builder shall have no further obligation to the Owner hereunder, or (ii) suspend performance of the Agreement until such
first Interim Installment Payment is received. In the event of such suspension, the Project Schedule, including the Delivery Date, shall be adjusted commensurately with the period of suspension. If the Builder has not achieved the progress of Work
required for an Interim Installment Payment, the Owner shall not be required to make the Interim Installment Payment until such time as the Builder certifies, to the satisfaction of the Owner, that it has achieved the Milestone necessary for the
Interim Installment Payment. 
 5.3 Except for the first Interim Installment Payment, the Builder shall furnish a Milestone Certificate for
each Milestone for any of the Vessels which shall state (i) the stage of Work achieved; (ii) that the Work completed complies with the Contract Documents; and (iii) that, subject to payment by the Owner therefor, there are no liens
upon said Vessel for labor or Materials covered by this Interim Installment Payment for said Vessel, except those created by the Owner, its subcontractors, vendors, or employees. The Milestone Certificate shall be executed and certified by the
President or Chief Financial Officer of the Builder. The Builder shall provide notice to the Owner within five (5) Working Days of receipt of any liens filed against the Work or a Vessel. If a lien claim is filed against the Vessel or the Work
on the Vessel or any portion of the Work is seized in connection with any asserted lien, the Owner shall not be obligated to make payment until the lien is resolved to the reasonable satisfaction of the Owner or the lien is fully released by bonding
or other appropriate means. Milestone Certificates for each Milestone shall be furnished to the Owner along with a Partial Lien Release(s) in the form of Exhibits L-1 and L-2 in favor of the Vessels and the Owner executed by the Builder and its
Subcontractors, as applicable. The Builder shall submit a Builder’s Invoice in connection with each Interim Installment Payment as set forth in Exhibit Q. 

5.4 The Builder will give the Owner written and electronic notice of the intended date of issuance of a relevant Milestone Certificate, not
more than ten (10) Working Days nor less than five (5) Working Days before issuance. The form of Milestone Certificate is attached as Exhibit F-1 to this Agreement. Except for the first Interim Installment Payment, and with respect to any
Interim Installment Payment which is disputed and subject to resolution pursuant to Article 5.5, Interim Installment Payments will be made by the Owner within ten (10) Working Days of receipt of the relevant Milestone Certificate, or within ten
(10) Working Days of resolution of such dispute under Article 5.5, accompanied by appropriate Lien Release(s) and Builder’s Invoice, in the form attached as Exhibit F-2 (except that the Delivery Payment will be made by the Owner upon
Delivery of the ATB Unit). 
 5.5 Except for disputes arising with respect to the final Milestone, if the Owner objects upon receipt of the
Milestone Certificate on grounds that the pertinent Milestone has not been reached, the dispute will be resolved pursuant to the provisions of Article 25 hereof.

 5.6 As of the time of Delivery of each Vessel, the Builder shall have executed and delivered
to the Owner (a) a Certificate of Completion and Delivery in the form of Exhibit H (including all documents listed therein) stating (i) that the Vessel has been completed, (ii) that all trials and tests have been satisfactorily
completed (except, if applicable, the System Tests), and (iii) that the Vessel complies with the Contract Documents and is free from any known defects in the Builder’s Materials and workmanship; (b) final lien waivers from the
Builder, in the form of Exhibits G-1 and G-2; (c) the Detail Design Drawings, including any and all modifications thereto to reflect the as-built design and construction of the Vessel which shall be delivered to Owner within five (5) Days
of Delivery if available but in no event later than thirty (30) Days after Delivery with the understanding that the Builder shall always use commercially reasonable efforts to deliver the as built drawings as expeditiously as possible upon or
after Delivery of each of the Vessels; (d) any other documents set forth in the Specifications; and (e) any other document reasonably required by the Owner, by applicable law or by any Regulatory Authority in order for the Owner to have
the Vessel documented in the Owner’s name and to allow the ATB Unit to commence operations as a trailing suction hopper dredge inspected under 46 C.F.R. Sub-Chapter C, and meeting Sub-Part I of Part 174, with a coastwise endorsement in the
United States, the foregoing being collectively referred to as the “Delivery Documents”. The Delivery Documents shall not include any certificate or approval from any Regulatory Authority required to be obtained by Owner as owner or
operator of the Vessels. Upon receipt of all Delivery Documents, the Owner shall execute and deliver to the Builder a Protocol of Delivery and Acceptance in the form set forth in Exhibit M. 

5.7 Upon Delivery as evidenced by a fully executed Protocol of Delivery and Acceptance or in the event the Owner refuses to accept a Vessel,
despite the Builder’s complete satisfaction and fulfillment of Builder’s obligations hereunder, the Owner shall pay the Builder: 
  

	 	1.	The Delivery Payments indicated in Exhibits Q-1 and Q-2; 

  

	 	2.	Plus any amounts due and payable by the Owner that have not been paid to date; 

  

	 	3.	Plus any applicable State or Local Sales and/or Use Taxes, unless the Owner has provided to the Builder documents required by Florida law to obtain a sales or use tax exemption (the Builder agrees to provide reasonable
assistance as requested by the Owner for obtaining any available exemption(s));

  

	 	4.	Plus or less any changes in the Contract Price resulting from fully executed Change Orders that have not been paid or credited prior to Delivery; 


 

	 	5.	Plus the cost of any stores paid for by the Builder on board the ATB Unit at the time of Delivery;

	 	6.	Less the liquidated damages for delay that may have accrued in accordance with Article 8 below. If the amount of liquidated damages payable pursuant to Article 8 shall exceed the sum of (1) through (5), above, the
Builder shall pay the difference to the Owner at the time of Delivery; and 

  

	 	7.	Less any Retained Amount. 

 5.8 In the event of any dispute between the Owner and the Builder at
the time of Delivery, which the Owner reasonably determines is not material to the functionality and performance of the Vessels and their systems, the Builder and the Owner shall reserve their respective rights regarding the dispute and Delivery of
the ATB Unit shall be made subject to such reservation. The Builder shall not withhold or otherwise delay or encumber the Delivery of the ATB Unit and the Owner shall not withhold acceptance of the ATB Unit or the payment of all amounts due and
payable pursuant to Article 5.7. The Builder shall deliver the Builder’s Certificate to the offices of Marine Documentation in Falling Water, West Virginia to be held in escrow and released upon the Owner’s payment of eighty percent
(80%) of the final payment for such Vessel to the Builder with the twenty percent (20%) balance of the final payment for such Vessel to be held in escrow by the law offices of Baker Donelson and released to the Builder upon the issuance of
the Certificate of Documentation by the U.S. Coast Guard National Vessel Documentation Center. 
 5.9 All payments will be due by wire
transfer or other payment in good funds unless otherwise specified herein. The Builder and the Owner shall furnish wire transfer payment instructions to the other party. Any and all late payments shall accrue interest at the thirty-day Libor rate
plus two percent (2%) from the date that the payment was due until paid. 
 5.10 Payments by the Owner shall be without prejudice to all
rights, defenses and remedies of the Owner in respect of the ATB Unit and this Agreement. 
 5.11 Additions, deletions or extra items
requested by the Owner from the Contract Documents shall be initiated and performed by the Builder without delay. Any increase or decrease in the Contract Price from a change or adjustment agreed to in accordance with Article 9 shall be deemed a
part of the Contract Price. Where the increase or decrease in the Contract Price has not been agreed upon, the Interim Installment Payment shall be estimated based on the Owner’s good faith estimate of the increase or decrease in the Contract
Price due to such change or adjustment, unless the Owner and the Builder agree otherwise. At the time the increase or decrease in the Contract Price is agreed upon between the Owner and the Builder, an appropriate adjustment will be made in the
subject Interim Installment Payments to reflect the variance, if any, between the Owner’s estimate and the agreed adjustment in the Contract Price. 

5.12 In the event that an increase or decrease in the Contract Price due to change or adjustment under Article 9 below is not mutually agreed
to prior to Delivery of the ATB Unit to the Owner, appropriate adjustment of any overpayment or underpayment shall be made promptly upon final determination in accordance with Article 25 as to the increase or decrease and any adjustments required to
the Contract Price shall be paid or refunded within ten (10) Working Days.

 5.13 If a change or adjustment shall result in an agreed increase or decrease in the Contract
Price for the ATB Unit, all Interim Installment Payments thereafter relating to the ATB Unit shall take account of such increased or decreased Contract Price. The first such Interim Installment Payment that becomes due after the subject increase or
decrease shall be adjusted by an amount equal to the product of (a) the amount of the increase or decrease in the Contract Price and (b) the aggregate percentage of the Contract Price required to be paid on or before the due date of such
Interim Installment Payment. 
 5.14 The Owner and the Builder agree that the sum of the Contract Price for the Vessels as set forth in
Exhibit A shall be paid by the Owner by the aggregate of (i) payments by the Owner to the Builder in accordance with the Tug Milestone Schedule set forth in Exhibit Q-1; and (ii) payments by the Owner to the Builder in accordance with the
Barge Milestone Schedule set forth in Exhibit Q-2. 
 ARTICLE 6 – PROSECUTION OF THE WORK AND PROJECT SCHEDULE 

6.1 In consideration for the Contract Price, the Builder shall provide all things required for the complete performance of the Work, except
for such items as are specifically required by the Contract Documents to be furnished by the Owner. The Builder shall at all times prosecute the Work diligently so as to ensure completion of the ATB Unit in full accordance with the Contract
Documents by the Delivery Date. The Builder shall at all times furnish sufficient numbers or amounts of properly skilled and qualified workers, acceptable materials and equipment and adequate services and tools and equipment necessary for the Work
and to ensure the delivery of the ATB Unit by the Delivery Date. 
 6.2 The Builder shall perform all of the Work in accordance with Good
Shipbuilding Practice, all applicable laws, applicable codes and standards, and the Contract Documents. All engineering and design services provided by Builder shall be provided utilizing Good Shipbuilding Practice and the generally accepted
standard of care, skill and diligence as would be provided by a national shipbuilder to the U.S. maritime industry. The ATB Unit shall be constructed in a good and workmanlike manner consistent with Good Shipbuilding Practice and in accordance with
the class standards set forth in the Specifications, Contract Documents and the requirements of the governing Regulatory Authorities. All Work of the Builder requiring certification shall be certified. 

6.3 The Builder understands that time is of the essence for the Owner and that an essential cause for the Owner’s decision to enter into
this Agreement with the Builder is the representation by the Builder that, except for causes of Force Majeure or other delays excused in accordance with the terms of this Agreement, the Builder can and will perform the Work and can and will deliver
the ATB Unit by the Delivery Date shown on Exhibit A. The Builder shall not take on additional work in its yard(s) which would adversely impact the delivery of the ATB Unit. In the event that the Builder is unable to complete and deliver the ATB
Unit by its Delivery Date as a result of a Force Majeure event or other event causing delay, the Builder will work with full dispatch in order to complete the delayed ATB Unit in the most timely manner achievable by the Builder, including, without
limitation, acceleration of the Work by all reasonable means available. In the event the delay is caused by a Force Majeure event or another

event which would allow Builder an extension of the Delivery Date under this Agreement, the additional cost including overtime incurred by the Builder to accelerate completion of the Work will be
the subject of a Change Order; provided, however, that the Owner shall have the right to review and approve any acceleration of the Work or any recovery plan proposed by the Builder before it is implemented by the Builder. The Builder shall not,
under any circumstances, make a decision that it is more economically advantageous for the Builder to pay liquidated damages than to allocate all necessary resources to the construction of the delayed ATB Unit that, if so allocated, would prevent
the delay or lessen the delay and the Owner shall have the right to a mandatory injunction requiring the Builder to complete the Work with all due diligence. Notwithstanding anything to the contrary in Article 25, the Owner may seek such mandatory
injunction in the exclusive venue selected by the parties in Article 25 hereof. 
 6.4 The Builder has provided to the Owner a
preliminary schedule attached hereto as Exhibit K. No later than thirty (30) Days following the execution of this Agreement, the Builder shall submit to the Owner a project schedule and execution plan (the “Project Schedule”) in
electronic form in its native format and a .pdf. The Owner and the Builder each acknowledge that the Project Schedule is a tool to be used to measure the Builder’s progress. Such schedule shall indicate dates for commencement, completion of the
Work, and an overall project execution strategy. All points of interface between the Owner and the Builder (i.e., all instances where performance of the Builder’s Work depends upon the Owner) and appropriate constraints shall be included in the
Project Schedule. In particular, the required delivery date of Owner Furnished Items shall be included in the Project Schedule so that the Owner may schedule its delivery to the Builder. In addition to any and all other parts of the Work shown, said
Project Schedule shall indicate the dates of expected completion of each Milestone task set forth in Exhibit Q. The Builder shall use and be entitled to rely upon information provided by the Owner for its installation of the Owner Furnished Items
and shall bear no liability for any critical path schedule impacts due to the late delivery of the Owner Furnished Items. Nonetheless, the Builder agrees to exercise due diligence to overcome the late delivery of any Owner Furnished Items that have
an impact on the critical path of the Project Schedule. If the Builder shall incur any additional expense, the Builder shall notify the Owner about the details supporting such additional expense and the Builder shall be entitled to a Change Order in
the agreed amount of such extra expense. 
 6.5 During the performance of the Work, the Project Schedule shall be updated to show the
progress of the Work and shall be submitted to the Owner for its review every four (4) weeks, commencing after the Builder’s submittal of the original Project Schedule and shall hold project status meetings with the Owner’s
Representative every week for the final eight (8) weeks. If the progress of the Work in comparison to the Project Schedule evidences that the Builder is not on schedule and the Owner so notifies the Builder, the Builder shall, within twenty
(20) Working Days thereafter, provide a recovery plan to the Owner for the Owner’s review and approval, which recovery plan must set forth a revised Project Schedule with a re-sequencing and/or acceleration of elements of the Work in order
to complete the ATB Unit by the Delivery Date. Except as provided to the contrary in Article 6.3, the Builder shall be responsible for all costs and expenses incurred by the Builder in the implementation of the recovery plan.

 6.6 The Owner acknowledges that the Functional Design Drawings, the Regulatory Approved
Drawings, the Barge Model (to the extent of functional design), the Tug Model (to the extent of functional design) and the Owner Furnished Items have critical importance to the maintenance and achievement of the Delivery Date. The Owner also
acknowledges that the failure to timely deliver the aforementioned items may cause a delay in the completion of the Work, and may cause Builder to incur additional costs over and above those projected for this Agreement. In the event that completion
of the Work is delayed as a direct result of Owner’s failure to timely provide the aforementioned items, the Delivery Date will be extended by a period equal to the period of the delay. In the event Builder incurs additional costs directly
related to the Work as a direct result of Owner’s failure to timely provide the aforementioned items, Owner shall compensate Builder for reasonable costs related to the Work that Builder may demonstrate as resulting from the delay. In all
instances of delay in delivery of the aforementioned items, Builder shall demonstrate that the path of the Work has been affected and that the Builder was not able to adjust the planned Project Schedule to avoid extension of the Delivery Date or the
incurrence of additional costs. In the event the Builder determines that the late delivery of the aforementioned items is affecting the Project Schedule such that the Delivery Date must be extended and/or that additional costs will be incurred by
the Builder as a direct result of such late delivery, the Builder shall notify the Owner in writing of such event as soon as possible but no later than fifteen (15) Working Days after knowledge thereof and provide all pertinent details and
documents to support any proposed extension of the Delivery Date and/or any additional costs the Builder anticipates incurring as a result of such delay. In the event the Builder is unable to quantify the expected delay or additional cost, the
Builder shall provide its best estimate and shall update and revise the estimate as additional information becomes available. The Builder shall be precluded from asserting any claim for an extension of the Delivery Date and/or for additional costs,
which is not timely made in accordance with this Article 6.6. Notwithstanding anything herein to the contrary, the Builder shall continue with the performance of the Work even if there is a dispute regarding the delay and cost effect of any
delay in providing the aforementioned items, which dispute shall be resolved pursuant to Article 25 hereof. 
 ARTICLE 7 –
FORCE MAJEURE 
 7.1 The Builder shall not be liable for failure to perform its obligation under this Agreement during such time
period the Builder’s performance is prevented by reason of a Force Majeure event. The Delivery Date of the ATB Unit shall be subject to extension by reason of Force Majeure provided that the critical path of the Work is shown to have been
affected by such Force Majeure event and the Builder is unable to reasonably adjust its planned Project Schedule. Subject to Articles 7.2 through 7.5, the parties agree that such causes shall include, but not be limited to, the following: all
strikes, lockouts, or any other industrial disturbance (not within the control of the Builder and not involving its own workers); shortages, unavailability, inadequacy or delays in receiving fuel supplies or electricity, supplies, Materials and
equipment (not within the control of the Builder); delivery of defective Materials and equipment (not within the control of Builder); acts of God, war, preparation for war, the intervention of the Military or other agencies of government, blockade,
sabotage (not involving the Builder’s own workers or the Builder’s Subcontractors), terrorism and vandalism (not involving the Builder’s own workers or the Builder’s Subcontractors), riots, insurrection; extraordinary rain,
landslides, floods, named tropical storms or hurricanes which affect the Builder’s shipyard, tornadoes, earthquakes, collisions, fire, epidemics and lightning. No such extension, however, shall suspend, alter or

affect the Builder’s right to receive or the Owner’s duty, if any, to compensate for all Work completed through the date of suspension. The Builder shall notify the Owner in writing
promptly of any Force Majeure event and shall furnish an estimate of the extent of any Force Majeure delay as soon as reasonably practical but not exceeding twenty (20) Working Days after learning of a Force Majeure event. The Builder shall
include with that notice (a) a description of the event, (b) its occurrence date, (c) its expected duration and (d) its expected effect on the Project Schedule and the Delivery Date of the ATB Unit. The Builder shall inform the
Owner in writing of the end of a Force Majeure event as soon as reasonably practical after its cessation but not exceeding twenty (20) Working Days and include an estimate of the delay in any Delivery Date, if any, caused by that event. Upon
receipt of the Builder’s notice of a Force Majeure event, the Owner shall, within ten (10) Working Days thereafter, either acknowledge in writing its agreement that such event is to be treated as a Force Majeure event, or state any
objections, and the reasons therefor, to acceptance of this event as a Force Majeure event. If the Owner objects to the Builder’s notice or does not respond within ten (10) Working Days, the matter shall be reserved and referred to
resolution under Article 25. If the Owner does not respond within ten (10) Working Days, the Force Majeure event shall be considered approved. If completion of the ATB Unit is delayed by a Force Majeure event, the Delivery Date of the ATB Unit
shall be adjusted by a period equal to the period specifically and exclusively resulting from the Force Majeure event. 
 7.2 Delays caused
by weather conditions shall only be Force Majeure where caused by landslide, lightning, flood, windstorm, hurricane, named tropical storm, earthquake, tornado or extraordinary rains which prevent Work occurring out of doors at the Builder’s
shipyard. 
 7.3 Delays caused by labor shortages and other shortages or inability to perform resulting directly from and that arise
immediately following named tropical storms or hurricanes shall only be considered Force Majeure if the Builder shall have provided to the Owner within ten (10) Days following its notice of the Force Majeure event a plan by the Builder
demonstrating that the Builder will take all reasonable efforts in order to mitigate the effects and delays arising from such shortages or inabilities to perform in an expedient manner. 

7.4 Should there be local area, state or federal government interferences in the Builder’s shipyard, this interference will only be
considered Force Majeure if exercised by the governmental entity pursuant to clear legal authority. If exercised without clear legal authority, it will only be considered Force Majeure if the Builder reasonably exercises its legal rights to oppose
such interference, by all reasonable legal means in order that interference will not cause delays in delivery of the ATB Unit. 
 7.5 It is
expressly understood by the Builder that delays in receiving supplies, materials and equipment shall not be considered Force Majeure unless (a) caused by strikes or lockouts of workmen other than those in the employ of the Builder, or
(b) the Builder establishes to the reasonable satisfaction of the Owner that (i) the Builder timely ordered and paid for as required such supplies, materials and equipment; (ii) the Builder exercised due diligence to obtain delivery;
(iii) no other source of supply was reasonably available; and (iv) the Builder is unable to reasonably adjust its Project Schedule to maintain scheduled critical path progress of the Work.

 7.6 Should the Builder claim adjustments to the Delivery Date for the ATB Unit for one
hundred and eighty (180) or more Days in the aggregate for reasons it claims are related to Force Majeure event(s), the Owner, at its sole option and in its discretion, shall have the right to terminate this Contract for convenience by giving
seven (7) Days prior written notice to the Builder of the Owner’s intent to terminate for convenience under this Article. In such event, the Builder shall release the ATB Unit, and the Work and any Materials or equipment relating thereto
to the Owner and invoice the Owner (a) for the portion of the Contract Price(s) allocable to the Work in progress performed on and Material commitments made for the ATB Unit as of the effective date of the termination, less the aggregate of
previous payments relating to the ATB Unit; and (b) for all documented expenditures made and costs incurred reasonably necessary to the settling or discharging outstanding commitments relating to the ATB Unit entered into by the Builder in
performing under this Contract. The Owner shall pay all undisputed amounts at the time the Builder releases the ATB Unit to the Owner with any disputed amounts being subject to the dispute resolution provisions of Article 25 of this Agreement.
In the event of termination for Force Majeure pursuant to this Article by the Owner, the Owner’s right to terminate shall be its sole and exclusive remedy and the provisions of Article 14 shall not apply and the termination shall not be deemed
to be on account of a Builder default. Unless specifically provided in this Agreement, the Owner shall not under any circumstances be responsible or liable to the Builder, or its Suppliers or Subcontractors of any tier, for any incidental,
consequential or special damages or expenses of any type or kind, including, but not limited to, loss of time, loss of profit or earnings, or losses related to detrimental reliance upon the existence of the Agreement, whether or not such losses
directly or indirectly arise out of the Agreement, or from any actions taken by the Owner at any time to terminate the Agreement. Extensions of the Delivery Date due to the delay of the Owner under Article 6.6 shall not be included in the
calculation of Days in connection with the Owner’s right to cancel under this Article 7.6. 
 ARTICLE 8 – LIQUIDATED DAMAGES

8.8 It is understood and agreed that in the event of late Delivery of 180 Days or less, the Owner shall suffer damages which are difficult to

 ARTICLE 9 – CHANGES IN THE WORK 

9.1 The Owner reserves the right to make any deductions from or additions to the Work on giving due notice in writing to the Builder, the cost
of any such changes to be agreed upon in advance by the Owner and the Builder, and added to, or deducted from the total Contract Price for the ATB Unit. If any such change will affect the current Delivery Date of the ATB Unit, or if any delays shall
have occurred which, according to the terms of this Agreement, require an adjustment of the Delivery Date, the Delivery Date shall be adjusted accordingly. A statement of the changes in the Work, including any increased or reduced amount of the
Contract Price, and/or any adjustment to the current Delivery Date, shall be submitted in a proposed Change Order to the Owner by the Builder. Said Change Order shall be agreed or disputed in writing by the Owner within ten (10) Working Days.

Contract, by Change Order, subject to the limitations herein.

adjustments in the Contract Price or adjustments of the Delivery Date, or Modifications in the Specifications or any Contract Documents or otherwise reach agreement upon the adjustments, such agreement shall be effective only upon execution of an
appropriate Change Order, signed only by the authorized signatories identified in Article 21.2. 
 9.5 If the Builder wishes to make a claim
for an increase in the Contract Price for any change in any part of the Work as a result of any change in the applicable rules of the Regulatory Agencies which require changes to the Contract Documents as contemplated in Article 2.6 or if the
Builder wishes to make a claim for an increase in the Contract Price for any variation between the Contract Drawings and the Functional Design Drawings which variation causes an increase in the cost to the Builder to build the Vessel, the Builder
shall give the Owner written

notice thereof in the form of a proposed Change Order. The Builder shall provide the proposed Change Order within fifteen (15) Working Days of the Builder’s discovery of any such change
in the Work. Except in an emergency endangering life or property in which case the Builder may proceed, the Builder shall not proceed with the claimed change in the Work covered by the proposed Change Order unless and until the proposed Change Order
has been approved in writing and signed by one of the authorized signatories of the Owner identified in Article 21.2, in the form of an approved Change Order. If the Owner and the Builder cannot agree on the entitlement to a Change Order, the amount
of the adjustment in the Contract Price or the adjustment of the Delivery Date, the Owner may direct the Builder to perform such Work and shall pay the Builder the undisputed amount of the Work (assuming the Owner concurs that there has been a
change in the Work but disputes the adjustment in the Contract Price requested by the Builder) performed in furtherance of the Change Order on the basis set forth in Article 9.1, without waiver of the Owner’s right to thereafter to submit the
disputed amount to resolution pursuant to Article 25 hereof. 
 9.6 Cost of any change considered an addition or a deletion shall be on a
fixed price basis, unless some other method of pricing is agreed by the Builder and the Owner. Cost of any change considered a substitution shall be the difference between the cost of the new substituted item and the originally specified item. 

9.7 Any Work performed on a time and material basis during the Agreement shall be based upon $60.00 per hour for labor. The Builder’s
mark-up for materials purchased from a third party shall be the Builder’s cost plus ten percent (10%). 
 9.8 Any Change Order in an
amount greater than $10,000 shall include an itemized breakdown of all estimated labor and materials to perform the Change Order and the Builder’s detailed computations of the projected cost of the Change Order.

disruption, cumulative impact, acceleration and like costs associated with, resulting from, or incidental to an approved Change Order including such costs that may be incurred by the Builder, its Subcontractors and its Suppliers. The Builder hereby
agrees that upon its acceptance of an approved Change Order, the Builder shall be deemed to waive and release all claims against the Owner for any and all additional costs or delays in a relevant Delivery Date, including, without limitation, costs
and delays based on any legal or equitable theory such as cumulative disruption or cumulative impact theories, resulting from an approved Change Order. 

9.10 No change in the Work under this Agreement, whether by way of alteration or addition to or deletion of the Work, shall be the basis of a
change to the Contract Price or a change in a relevant Delivery Date unless and until such alteration or addition or deletion has been authorized by a Change Order executed and issued in accordance with and in strict compliance with the requirements
of this Article 9.

or ways from any cause whatever, and all liability risks of the Builder and the Owner with respect to construction and delivery of the Vessel. Any provisions of the Builder’s Risk Insurance liability coverages that would limit liability

additional insured with the same provisions as noted for the $25,000,000 minimum limit. 
 10.2 Prior to Work, the Builder shall procure,
from each of its insurers, in respect of risks assumed by the Builder under this Agreement, a written and enforceable specific endorsement of the Builder’s policies (excluding worker’s compensation, which is noted below) to provide a

The Builder agrees that its policies shall be primary in all cases. Any insurance that may be carried by the Owner shall be excess over and above the amount recoverable under the policies of the Builder. The policies of insurance procured by the
Builder shall acknowledge that said policies are primary, and that no pro-rata contributions are required by the Owner and/or any member of Owner Group and/or the Owner’s insurers and/or Owner Group’s insurers. The Builder further agrees
that its worker’s compensation insurance policies shall be endorsed to designate the Owner Group, as defined in Article 23, and their successors and assigns, as an alternate and statutory employer and shall be endorsed to provide a blanket and
unrestricted waiver of its underwriters’ or insurers’ rights of subrogation. All deductibles will be for the account of the Builder.

evidence of insurance (including Longshore and Harbor Worker’s Compensation coverage) naming the Builder as an alternate and statutory employer and shall be endorsed to provide a blanket and unrestricted waiver of its underwriters’ or
insurers’ rights of subrogation, which covers them under commercial terms and limits consistent with Builder’s Insurance Requirements for Companies with Employees Working at Builder’s Facilities dated July 1, 2010, at no cost or
expense to the Builder. 
 10.5 Partial Loss: If any Vessel, and/or Materials, Work, and/or Owner Furnished Items relating to
that Vessel is damaged by any cause whatsoever prior to the Delivery Date of the Vessel, and such damage does not constitute a total loss, the proceeds of insurance up to an amount of $1,000,000 in respect of such damage payable under the
Builder’s Risks Insurance policy required in accordance with Article 10.1(c) shall be payable to Builder, who shall use the monies exclusively for the repair of such damage, as soon as reasonably practicable, all in accordance with the
requirements of this Agreement and the Specifications and to the satisfaction of the classification society, any applicable Regulatory Authorities, and the Owner’s Representative. The Builder will provide the Owner with documentation to
verify the proper use of the insurance proceeds to fully repair the damage or loss to the Vessels(s). Any insured loss in excess of $1,000,000 resulting from such damage or loss shall be payable jointly to Owner and Builder, and deposited in an
escrow account established by the Owner and the Builder and paid to the Builder in accordance with a new milestone payment schedule for the repairs, to be agreed between the Owner and the Builder, which schedule shall provide for timely payment to
Builder of sums required for deposits on necessary Materials, and timely payment for repair work performed. If repairing the damage will unavoidably have the effect of delaying the Delivery Date of the Vessel, then the damage may be deemed a
Force Majeure event and the provisions of Article 7.1 shall apply; provided, however, if the loss or damage is caused by the negligence of the Builder or any of its Subcontractors or the Builder’s breach of this Agreement, liquidated damages
shall be owed to the Owner for any extension of the Delivery Date due to such loss or damage subject to the limitations of Article 8 hereof. 

10.6 Total Loss: In the event that any Vessel becomes an actual or agreed or constructive total loss within the terms of the
Builder’s Risks Insurance required in accordance with Article 10.1(c), Owner, in its sole discretion, may elect within thirty (30) Working Days after the Vessel is determined to be an actual or agreed or constructive total loss, either:

  

	 	(i)	to have Builder commence construction of a new Vessel for Owner pursuant to the terms and conditions of this Agreement, at a new mutually agreed Delivery Date, Contract Price and Interim Installment Payment Schedule, in
which event the insurance proceeds shall be paid to Owner, or

	 	(ii)	to terminate this Agreement, as to the total loss Vessel, upon the happening of which Owner shall be relieved of any further obligation to Builder under this Agreement relating to that Vessel (except that the Owner
shall pay to the Builder for any Work performed and Materials supplied by the Builder up to the date of such Total Loss), and Owner shall be entitled to receive and shall be paid directly from the builder’s risk insurer an amount equal to the
total of: 

  

	 	A.	all payments relating to the Vessel previously made to Builder by or on behalf of Owner, plus 

  

	 	B.	the total costs of any Owner Furnished Items relating to that Vessel, including installation. 

 Collectively, A
and B above, the “Total Loss Amount.” 
 10.7 In the event the Owner elects to exercise its option under Article 10.6(i), the
Contract Price for the rebuilt Vessel(s) shall only be adjusted by the Builder’s demonstrated increase in its cost to rebuild the Vessel over its original Contract Price, including the Builder’s profit and overhead. 

10.8 Upon Owner’s election under Article 10.6(ii) for payment in full of the Total Loss Amount to the Owner, Owner shall have the first
option ahead of the Builder to purchase the Vessel(s) in its current state from the Builder’s risk insurer. If Owner does not elect to purchase the Vessel(s), the Builder may purchase the remains of the Vessel(s) and the Work, Materials and
Owner Furnished Items relating to the subject Vessel(s) from the Builder’s risk insurer. In such event, the Builder shall ensure that the Intellectual Property of the Owner is fully protected. 

ARTICLE 11 – WARRANTY 

11.1 The Builder shall designate at least sixty (60) Days prior to Delivery, a Warranty Manager for the ATB Unit. The Warranty Manager
shall be familiar with the Work and all of the Builder’s Suppliers, vendors and/or Subcontractors. The Warranty Manager shall work with the Owner’s Representative in (i) understanding the nature of any warranty claim;
(ii) coordinating with the Builder or the Builder’s Suppliers, vendors or Subcontractors a remedy; and (iii) assisting in coordinating payments on any third-party vendor or Subcontractor work. Within a reasonable time but in any event
no later than twenty (20) Working Days after becoming aware of a warranty claim, the Owner shall issue a warranty notification to the Builder in the form of Exhibit J (“Warranty Notification”). Upon receipt of a Warranty Notification,
the Warranty Manager will take all reasonable steps, as outlined above, to resolve the claim. 
 11.2 The Builder warrants that the Work and
the ATB Unit are constructed in accordance with the Contract Documents and shall be free from defects in workmanship and materials for a period of three hundred sixty-five (365) Days after the Delivery of the ATB Unit. The Builder will replace
or repair any defects in its Work that are discovered within such three hundred sixty-five (365) Day period. The Owner shall notify the Builder of any defects it may discover in a prompt manner but in no event later than thirty (30) Days

replaced or repaired Work for an additional (i.e. after the three hundred sixty-five (365) Day period has expired) ninety (90) Day period after satisfactory completion of the repair
Work. Under no circumstances shall the warranty on any Work exceed four hundred fifty-five (455) Days from Delivery of the ATB Unit. Where, because of the geographical distances involved, it would be impractical to return the ATB Unit to the
Builder for repairs or replacements under this warranty, the Owner, after giving reasonable notice to the Builder in order to allow the Builder, at its option, to inspect such alleged defect(s) and make the necessary repairs or replacement, and if
the Builder elects not to make such repairs at the location of the ATB Unit in an expedient manner or at another reputable shipyard selected by the Builder and reasonably acceptable to the Owner, the Owner may effect the necessary repairs at other
available facilities, and the Builder will reimburse the Owner for those costs, including mobilization and demobilization of the Vessel(s); provided, however, in no circumstances, shall the amount of reimbursement of costs of making the repairs
(including mobilization and demobilization) exceed the costs calculated on the time and material rates as set forth Article 9.7. Nothing contained herein shall obligate the Builder at any time to repair or replace the ATB Unit, or any Work or
component part thereof, where and to the extent such repair and/or replacement is caused by ordinary wear and tear or the negligent operation or maintenance of the ATB Unit, or its equipment, by the Owner or third parties. 

11.3 The Builder shall use its commercially reasonable efforts to effect warranty repairs without necessitating that the ATB Unit be removed or
prevented from commercial service to the benefit of the Owner. 
 11.4 The Builder shall advise the Owner of, and deliver the original
documentation for, any manufacturer’s warranties applicable to equipment or Materials furnished by the Builder or its Subcontractors or Suppliers and the Builder shall make reasonable efforts with the manufacturer to arrange for warranties to
commence in favor of the Owner on the date of Delivery of the ATB Unit. The Builder shall assign, convey and transfer over to the Owner any warranty issued by any third party for any Materials purchased by the Builder and installed on the Vessels.
In the event that any such third party warranty cannot be enforced directly by the Owner, the Builder shall provide reasonable assistance to the Owner for enforcement of such warranties. The Builder shall provide the Owner with any standard
commercially available operating and maintenance manuals with respect to all equipment installed in the Vessels in accordance with the quantities set forth in the Specifications. The Builder’s warranty expressly excludes defects in equipment,
Design (but excluding Detail Design Drawings which are the responsibility of the Builder), or Materials manufactured by others or provided by the Owner, but shall include any defects related to installation of Materials. 

11.5 Without limiting the warranty of Article 11.2, if within three hundred sixty five (365) Days after Delivery of the ATB Unit, any of
the Work performed by the Builder or its Subcontractors and warranted hereunder is found to be not in accordance with the requirements of the Contract Documents, the Builder shall correct it promptly after receipt of written notice from the Owner to
do so in accordance with Article 11.1. It shall be the duty and obligation of the Owner to within thirty (30) Days of becoming aware give the Builder written notice after discovery thereof of the failure of any part of the Work as a result
of defective workmanship or defective materials, giving full information as supported by photographs, where possible.

that it will prepare the surface and apply the paint in accordance with the manufacturer’s specifications and recommendations, and the Builder makes no warranty, express or implied, with respect to the fitness of the specified paint or the
manufacturer’s specifications and recommendations. The Builder will require the paint and/or coatings manufacturer’s field representative to be present at the time the Builder is applying paint and/or coatings and shall obtain the
representative’s approval for the paint and/or coating systems to be applied and the preparation and procedures being followed by the Builder. The Owner shall be provided with a copy of all inspection reports provided to the Builder by the
representative. The Builder shall provide reasonable assistance to the Owner to obtain paint warranties from the paint manufacturers, and any warranty defects with respect to the paint or coatings systems shall be asserted by the Owner only against
such manufacturer. 
 11.7 Except for the expressed limited Warranty set forth in this Article 11, the Owner hereby waives and releases
the Builder and its employees from and against damage to and/or loss of the ATB Unit, delay, demurrage, loss of profits, loss of use, or any other consequential or punitive damages of any kind, whether such claim is based in contract, redhibition,
negligence, strict liability, or otherwise, arising out of any defect and/or negligent design, the selection or choice of specifications and/or materials and/or component parts, manufacture, construction, fabrication, workmanship, labor and/or
installation of equipment, materials and/or components or from any unseaworthy condition or any other defective condition of the ATB Unit, it being specifically understood and agreed that any such defects reported and/or occurring after the Warranty
Period (and the extension of any Warranty Period) and all damages to the ATB Unit, loss of profits, demurrages, delay, losses of use or other consequential or punitive damage of any kind whatsoever resulting therefrom, shall not be the
responsibility of the Builder. 
 11.8 THE WARRANTY EXPRESSLY PROVIDED IN ARTICLE 11 IS EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES, EXPRESS
OR IMPLIED BY LAW OR OTHERWISE, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR THAT THE ATB UNIT’S MATERIALS OR SERVICES ARE FIT FOR ANY PARTICULAR PURPOSE OR USE, AND THE REMEDIES PROVIDED HEREUNDER ARE THE OWNER’S SOLE AND EXCLUSIVE REMEDY
FOR BREACH OF WARRANTY AND ARE SPECIFICALLY IN LIEU OF ALL OTHER REMEDIES OR DAMAGES, WHETHER DIRECT, INDIRECT, SPECIAL, PUNITIVE OR CONSEQUENTIAL. 

ARTICLE 12 – PAYMENT AND PERFORMANCE BONDS 

12.1 The Builder shall obtain payment and performance bonds in form and substance reasonably acceptable to Owner issued by a financially sound
surety naming Owner as Obligee guaranteeing the payment and performance obligations of Builder in the maximum amount of $30,000,000.00 at a cost to be paid 50/50 by the Owner and Builder (the “Financial Security”). The aforesaid bonds must
be furnished to the Owner within thirty (30) Days after the Effective Date of this Agreement or prior to commencement of Work, whichever occurs sooner.

 12.2 If any Financial Security required under this Article 12 has not been issued and
delivered to the Owner when due by the Builder, the Owner shall have the option, in its sole and absolute discretion, to terminate this Agreement by giving seven (7) Days prior written notice to the Builder of termination under this Article
unless the Builder shall have delivered the required Financial Security to the Owner prior to the end of such seven (7) Day period.

insolvency or for reorganization or for the appointment of a receiver or trustee of all or a portion of the Owner’s property, or an order of discharge of the Owner is ordered by said Court; 

14.8.3 The Owner makes an assignment for the benefit of creditors or petitions for or enters into an agreement or agreements with its

14.8.4 The Owner, without limitation, fails to perform any other material obligation of the Owner under this Agreement. 

14.9 If the Owner fails to timely cure a default in accordance with Article 14.8.1, then the Builder may, in its sole discretion, suspend or
reschedule progress of the Work (such right being in addition to any other right granted hereunder or by operation of law) until such time as it receives the overdue payment from the Owner. In the event the Owner has disputed that the amount claimed
by the Builder is due, in whole or in part, and so long as the Owner has paid any undisputed portion of the claimed amount due, the Builder shall continue with the Work with all due diligence and in accordance with this Agreement. Furthermore,
whether or not the Builder has suspended or rescheduled progress of the Work as aforesaid, if an event of default set forth in Article 14.8 occurs, the Builder may elect to terminate this Agreement after giving thirty (30) Days written notice
to the Owner of its intent to terminate. However, during the thirty (30) Day period referred to above, the Owner shall have the absolute right to cure any such default. If such default is not timely cured, the Builder may, at its option,

condition and location at a public auction announced at least twenty (20) Days in advance in the Houston Chronicle and Wall Street Journal provided at least twenty (20) Days advance written notice of the auction has been
provided to the Owner, or (iii) complete the Vessels for sale to a third party and apply the proceeds of sale, net of all expenses, to any unpaid balance due and owing to the Builder. The excess proceeds from any such auction or sale shall be
paid to the Owner. Nothing in this Article 14.9 shall preclude additional notice by the Builder or the Owner of any such auction or sale on any industry trade internet sites. 

14.10 Delay by the Owner or its representatives in providing to the Builder or its agents any Owner-supplied information, documents and/or
goods or materials for the construction of the ATB Unit shall be covered by the appropriate provisions of Article 9 relating to Changes in the Work. 

14.11 The failure of either party to exercise any rights conferred upon it under any provision of this Agreement or applicable law with respect
to any breach or default by the other party shall constitute neither a waiver of its rights under any other provision of this Agreement with respect to such breach or default, nor a waiver of its rights under the same or any other provision of this
Agreement with respect to any other breach or default.

ARTICLE 22 – TITLE AND SECURITY 

22.1 Title in and to the Vessels as they are constructed shall progressively vest, and once vested shall in all events remain, in the Owner,
not the Builder, as the Vessels are constructed to the extent the Interim Installment Payment pertaining to that portion of the Work has been paid by the Owner. Title to all Materials and equipment or other items furnished by the Builder shall vest
in the Owner when the same has been paid by the Owner. Without regard to the provisions of this Article 22.1, the Builder shall be subject to the risk of loss of the Vessels and their Materials and the Work until completed and the ATB Unit is
delivered to and accepted by the Owner and an executed Protocol of Delivery and Acceptance is delivered as provided in this Agreement. The Owner’s title to the Vessels, the Materials and the Work is subject to a possessory lien and any
applicable security interest in favor of the Builder to the extent, if any, that the Builder has not been paid. 
 22.2 If, notwithstanding
the express provision of Article 22.1 or otherwise of this Agreement, the Vessels or any of the property to which the Owner holds title as described in this Article, is for any reason deemed by any court of competent jurisdiction not to be the
property of, and owned by, the Owner, the Builder, to the extent it has any interest therein, alternatively hereby grants a first priority security interest in the Vessels and all of such property in favor of the Owner. The security interest granted
hereby in the alternative shall secure all of the Builder’s obligations to the Owner under this Article. The Owner shall have the right to file without any further consent or signature of the Builder one or more UCC 1 Financing Statements at
Owner’s expense against the Builder covering the Vessels and any or all of such property. In such Financing Statement(s) the Owner shall be entitled to give notice of its ownership of the Vessels and other property, and in the alternative, its

ARTICLE 24 – Reserved 

ARTICLE 25 – DISPUTE RESOLUTION 

25.1 Whenever disputes, disagreements, or misunderstandings arise, the Builder and the Owner will attempt to resolve the issue(s) involved by
good faith discussion and mutual agreement as soon as practicable. 
 25.2 Failing resolution by mutual agreement, the aggrieved party shall
document the dispute, disagreement, or misunderstanding by notifying the other party in writing detailing the relevant facts, identifying unresolved issues, specifying the clarification or remedy sought, and detailing the rationale as to why the
clarification/remedy is appropriate. The other party shall submit a written position on the matter(s) in dispute within ten (10) Working Days after being notified. The parties will then meet within five (5) Working Days thereafter to
further discuss the issue(s) in dispute and such meeting will include a duly authorized officer of the Owner and a duly authorized officer of the Builder. If this process does not resolve the dispute, the aggrieved party may then pursue resolution
under the remaining provisions of this Article 25. 
 25.3 Articles 25.3 through 25.5 shall only apply to disputes that have a monetary
value, excluding costs and attorneys’ fees of less than $500,000. For the purposes hereof, those types of disputes shall be described as a “Work Dispute.” Work Disputes shall be subject to Articles 25.4 through 25.5 and decided by an

 25.4 Work Disputes shall be submitted to the Surveyor who shall be experienced in
shipbuilding matters. The parties agree to utilize an experienced and independent marine surveyor from Dufour, Laskay & Strouse, Inc. (“DLS”) to serve as the Surveyor. In the event DLS has a conflict of interest, refuses, or is
otherwise unable for any reason to timely decide the Work Dispute, the Work Dispute shall be submitted to a qualified marine surveyor selected by the ABS. 

25.5 To invoke the process under Article 25.3, either party shall provide written notice to the other party pursuant to Article 21, with a copy
to the Surveyor setting forth: 
  

	 	(a)	the issue(s) to be decided by the Surveyor; and 

  

	 	(b)	that resolution under Article 25.3 is requested. 

 25.6 Articles 25.6 through 25.20 shall only
apply to disputes that have a monetary value, excluding costs and attorneys’ fees of more than $500,000 but less than $3,000,000. For the purposes hereof, this type of dispute shall be described as an “Arbitration Dispute.” Any
dispute other than an Arbitration Dispute arising between the Owner and the Builder, relating to the interpretation or performance of this Agreement, shall not be subject to this arbitration provision, and there shall be no compulsory arbitration
except in the case of an Arbitration Dispute. Arbitration Disputes shall be subject to the arbitration provisions herein provided. 
 25.7
Arbitration Disputes shall be submitted to arbitration. No more than ten (10) Working Days after a party has invoked arbitration as set forth in Article 25.8 below, each party shall select an arbitrator and notify the other party of the
arbitrator selected. All arbitrators shall be selected from the list of approved arbitrators of the Society of Maritime Arbitrators and shall be knowledgeable with commercial shipbuilding practices. The two (2) arbitrators so selected shall
then select a third arbitrator from the list of approved arbitrators of the Society of Maritime Arbitrators within ten (10) Working Days of the date of the selection of the last party appointed arbitrator. If any party or the two
(2) arbitrators fail to timely appoint the third arbitrator, the arbitrator shall be selected from the approved list of arbitrators of the Society of Maritime Arbitrators. The arbitrators shall decide on each issue or dispute presented to them
by a majority vote. In all circumstances, the arbitration shall be conducted in New Orleans, Louisiana. 
 25.8 To invoke arbitration under
this Article 25.7, a party shall provide the other party written notice of its decision to invoke arbitration, which written notice shall also set forth the following: 
  

	 	(a)	The disputes or issues to be arbitrated, including a concise statement of the factual basis therefor and a reference to the relevant provisions of the Contract Documents related to such disputes or issues to be
arbitrated; and 

  

	 	(b)	That arbitration is demanded. 

 25.9 The arbitrators shall not be bound by the rules of evidence
or civil procedure, but rather may consider such writings and oral presentations as reasonable shipbuilders and businessmen would use in the conduct of their day-to-day affairs, and may require the parties to submit some or all of their presentation
orally or in written form as the arbitrators may deem

appropriate. The parties acknowledge that arbitrations should be conducted in a more cost efficient and timely basis than court litigation. Nonetheless, the parties agree that some limited
discovery is appropriate to ensure a full and fair hearing. Accordingly, the parties agree to the following limited discovery in the event of an Arbitration Dispute: (i) the exchange of all documents and things which are relevant to the
disputes or issues submitted to the arbitration panel (“Initial Exchange”) which Initial Exchange shall include documents and things that are both supportive and not supportive of a party’s position; (ii) interrogatories and
requests for production of documents and things, each of which shall not exceed twenty (20) in number, including subparts (“Written Discovery”); (iii) documents only subpoenas on third parties; and (iv) five
(5) depositions per party. The parties shall conduct the Initial Exchange no later than thirty (30) Days after the third arbitrator is selected. All Written Discovery shall be exchanged within fifteen (15) Days of the Initial
Exchange. The parties shall respond to the Written Discovery within twenty (20) Days from receipt thereof. All depositions shall be scheduled within forty (40) Working Days after receiving responses to Written Discovery. In the event
either party believes additional discovery is needed for a full and fair hearing of the disputes or issues, a party may submit a request to the arbitration panel for such additional discovery, which shall be permitted by the arbitration panel for
good cause shown. 
 25.10 The parties may follow such rules and procedures as are agreed to between the parties. If the parties cannot agree
to such rules and procedures within ten (10) Working Days of an election to submit the dispute to arbitration, then the Commercial Arbitration Rules of the American Arbitration Association shall apply. 

25.11 Any arbitration may include any other person substantially involved in a common question of fact or law whose presence is required if
complete relief is to be accorded in arbitration, provided that such other person has agreed to be bound by such arbitration. 
 25.12 The
arbitration panel shall have the authority to retain such impartial expert assistance as they deem necessary to assist them in making a full and fair evaluation of the claims of the parties and to include the cost of arbitration reasonable
compensation and reimbursement of expenses for any expert so retained. 
 25.13 Either party may apply to the arbitration panel seeking
injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any interim or provisional relief
that is necessary to protect the rights or property of that party, pending the establishment of the arbitration panel (or pending the arbitration panel’s determination of the merits of the controversy). 

25.14 The arbitral award shall be made and payable in United States dollars, free of any tax, deduction or off-set and in accordance with the
arbitral award. The arbitration panel shall use all reasonable efforts to render a decision within 210 Days following the appointment of the third arbitrator.

regarding any claims, counterclaims, issues, or accountings presented or pled to the arbitration panel. Neither party shall have the right to commence or prosecute any action before any court on any dispute, conflict, or controversy arising out of
or in relation to this Agreement, except for an action to compel arbitration in accordance with this Article or for provisional relief in accordance with Article 25.13, or for enforcement of the decision(s) and/or award of the arbitration panel.

 25.19 Neither a party nor an arbitrator may disclose the existence, content, or results of any arbitration hereunder without the prior
written consent of both parties.

litigated by the parties in federal district court in the Eastern District of Louisiana, which the parties have mutually selected as the exclusive venue for any such litigation. The parties agree and waive any objection to the inconvenience of the
venue and further waives the right they may have to a trial by jury. 
 ARTICLE 26 – TAXES, DUTIES, AND 

CONTRACT EXPENSES 

26.1 The Builder shall pay all local, state, and federal taxes, federal import duties, workers’ compensation, social security or old age
benefits of any nature, unemployment tax, and any other similar taxes, charges, assessments and contributions of any kind now or hereafter payable in connection with the construction of the Vessels imposed upon, or with respect to, or measured by,
Materials and labor utilized in the construction of the Vessels, or the wages, salaries or other remunerations paid to persons employed in connection with the performance of this Agreement, and the Builder shall indemnify and hold the Owner harmless

 26.2 The Owner agrees to pay such state or local sales or use or other taxes, if any, as may
be mandatorily imposed by law in connection with the sale and Delivery of the Vessels. It is the intention of the Owner, however, to avoid or minimize, to the greatest extent lawfully possible, the imposition of any state sales or use or other taxes
with respect to the Vessels. This may involve claiming any lawfully available exemption(s), such as the “removal” exemption, the “interstate or foreign commerce” exemption, the “resale” exemption, or taking delivery of
the ATB Unit in a location outside the boundaries of the State of Florida. The Builder shall use reasonable efforts to cooperate with the Owner to achieve exemption from such sales or use or other taxes, but only to the extent permitted by
applicable laws and regulations, and shall provide the Owner with all such documentation as may be needed from the Builder to assist the Owner in establishing exemption from such sales or use or other taxes. 

ARTICLE 27 – LIENS AND ENCUMBRANCES 

27.1 Following payment of the sums due to the Builder by the Owner hereunder, the Builder agrees to deliver the ATB Unit to the Owner free and
clear of any and all liens, claims, encumbrances and rights in rem in favor of the Builder or any workmen, material men, Suppliers, Subcontractors, or others to whom the Builder is responsible, excluding liens, mortgages or encumbrances created by
the Owner. 
 27.2 Provided that the Owner has complied with its payment obligations, in the event of the filing or attaching of any lien or
encumbrances created or suffered by or through the Builder or any of its Subcontractors or Suppliers against the Vessels before final payment, the Owner may, but shall not be required to, satisfy the same out of any amount remaining to be paid to
the Builder hereunder, except where the Builder notifies the Owner of a bona fide dispute between the Builder and such lienor. When final payment is to be made under this Agreement, as condition precedent thereto, the Owner may, in its discretion,
require that the Builder provide to the Owner a statement certifying and indemnifying the Owner against any liens or rights in rem of any kind against the ATB Unit or its respective machinery, fittings, or equipment which relate to actions of the
Builder and excluding any liens or encumbrances created by the Owner. 
 27.3 In addition to and notwithstanding the foregoing, and provided
that the Owner has complied with its payment obligations, the Builder agrees to be fully responsible for and to defend, indemnify the Owner and hold it harmless from and against all liens and claims for labor, material, taxes, privileges and
licenses arising out of, in connection with, or resulting from the operations or activities of the Builder, its employees or agents or Subcontractors and the employees or agents of their Subcontractors, and agrees to defend any such claim asserted
or suit brought against the Owner and/or the Vessels and to pay any judgment rendered in any such action and reimburse the Owner for any attorneys’ fees and costs it may have incurred in the enforcement of this indemnity, provided, however,
that the Owner shall have the right, if it so elects, to participate at its own expense in the defense of any such claims or suits, but such participation shall not operate to affect the Builder’s liability and obligation hereunder.

 The Contract Price shall be adjusted either up or down at the value specified below for each short ton
difference between the applicable Vessel’s actual neat steel weight and the neat weight allowance noted below. For purposes of adjusting the Contract Price, the actual neat steel weight shall be that weight of the applicable Vessel’s hull
structural steel assembly as derived from the Vessel’s modeled configuration using the fabricated scantlings and the engineering software “Ship Constructor.” 

Barge – [*] per short ton* 
 Tug – [*] per short ton*

 Barge 
 It is emphasized that every effort
shall be made to minimize unnecessary Barge weight, particularly structural weight. To that end, where applicable, Builder shall work with the Owner to identify areas where “or equal” substitutions (including high strength steel) have the
potential to result in significant weight savings, subject to Builder’s right to a Change Order in accordance with Article 9. 
 The Contract price for
the Barge hull noted above includes a neat steel weight allowance of [*] Short Tons less Owner furnished steel consisting of [*] A36 and [*] EH36. For purposes of this Agreement, neat steel weight is defined as the Barge’s hull structural steel
assembly as noted in the Construction Specification for the Barge (Exhibit B), Sections 2.100, 2.200, 2.300, 2.400, 2.450, 2.500 (excluding fluidizing piping and bottom doors), 2.570, 2.600, 2.650, 2.670, 3.100 and 3.200, trimmed and fitted for
weldout and is exclusive of any drop-offs, paint and pre-construction primer, welding or welding electrodes, construction or erection padeyes/brackets, or other construction weldments or appurtenances. 

Tug 
 It is possible that in the course of Tug
design development, it becomes necessary to increase hull scantling sizes in order for the Tug to achieve the design draft. The Contract Price for the Tug hull noted above includes a neat steel weight allowance of [*] Short Tons. For purposes of
this Agreement, neat steel weight is defined as the Tug’s hull structural steel assembly as noted in the Construction Specification for the Tug (Exhibit B), Sections 2.6, 2.7, 2.8, 2.9, 2.10, 2.11, 2.12 and 2.13.5, trimmed and fitted for
