Introductory

Note

August 31, 2026 (the “Closing Date”), Tidewater Inc., a Delaware corporation (“Tidewater” or

the “Company”), completed its acquisition (the “Transaction”) of all outstanding capital stock of

Wilson, Sons Ultratug Participações S.A. (“WSUT”) and Atlantic Offshore Services S.A. (together with

WSUT, the “Target Companies”). As a result of this Transaction, the Company acquired the assets owned by the Target

Companies and their wholly owned subsidiaries, which include a fleet of 22 platform supply vessels.

Item

1.01

Entry into a Material Definitive Agreement.

Amended and Restated Sale and Purchase Agreement

previously disclosed, on February 22, 2026, the Company entered into a Sale and Purchase Agreement (the “Original SPA”),

by and among Wilson Sons S.A. (“Wilson Sons”), Ultranav International II, S.A. (“Ultranav”), Remolcadores

Ultratug Limitada (“Remolcadores”, together with Wilson Sons and Ultranav, the “Sellers”), the

Target Companies, the Company, and Pan Marine do Brasil Ltda., a company incorporated in Brazil and a wholly owned subsidiary of the

Company, and Tidewater Marine International, Inc., a company incorporated in the Cayman Islands and a wholly owned subsidiary of

the Company (collectively, the “Tidewater Purchasers”, together with the Company, the “Tidewater Parties”).

On August 25, 2026, the Sellers, the Target Companies and the Tidewater Parties entered into an Amended and Restated Sale and Purchase

Agreement (the “Amended & Restated SPA”), to: (a) allow for the consummation of the Transaction prior

to the replacement of certain parent company guarantees in respect of the Target Companies’ BNDES Construction Loans (as defined

below) (the “BNDES Parent Company Guarantees”); (b) provide for the covenant of the Tidewater Parties described

under “Replacement of BNDES Parent Company Guarantees” below; (c) clarify the means by which certain parent company

guarantors in respect of the BB Loan (as defined below) with Banco do Brasil S.A. (“BB”) will be released, as a condition

to closing the Transaction; (d) allow for the parties to agree to complete the Transaction on August 31, 2026; and (e) amend

certain other ancillary matters. The foregoing description of the Amended and Restated SPA and the transactions contemplated thereby

are subject to and qualified in their entirety by reference to the Amended and Restated SPA, which is filed as Exhibit 2.1 hereto,

the terms of which are incorporated herein by reference.

Replacement

of BNDES Parent Company Guarantees

connection with and pursuant to the Amended and Restated SPA, as soon as reasonably practicable following the Closing Date but prior to

December 31, 2026, the Tidewater Parties are required to use best endeavors to: (a) (i) replace the BNDES Parent Company

Guarantees or (ii) repay in full the amounts outstanding of such certain loans contained therein; and (b) terminate the BNDES

Parent Company Guarantees and fully release in writing each relevant Seller from any obligation and liability in respect thereof. To support

and backstop the Company’s obligations to indemnify the relevant Sellers in respect to the replacement of the BNDES Parent Company

Guarantees, the Company procured unsecured bank guarantees from DNB Bank ASA not to exceed the amount of USD $170,458,000 (the “Replacement

LCs”) in effect prior to the Closing Date. In connection with the issuance of the Replacement LCs, Tidewater is required to

maintain minimum liquidity (defined as unrestricted cash plus undrawn capacity under any of the Company’s revolving credit facilities)

in an amount at least equal to 1.25x of the total outstanding amount of the Replacement LCs. For so long as each Replacement LC remains

in full force and effect in accordance with its terms and conditions, the relevant Seller may make a written demand for payment in respect

of the Tidewater Parties’ indemnification obligations in connection with replacing the BNDES Parent Company Guarantees, including

for any steps taken in relation to an enforcement action by Banco Nacional de Desenvolvimento Econômico e Social (“BNDES”),

subject to the terms and limitations set forth in the Amended and Restated SPA. The Replacement LCs serve to additionally support the

covenant of the Tidewater Parties to replace such BNDES Parent Company Guarantees by December 31, 2026. The Replacement LCs will

remain in effect until the earlier of December 31, 2026 and the date on which DNB Bank ASA receives a written notice from the Company

and the Sellers requesting termination of the Replacement LCs. Pursuant to the Amended and Restated SPA, the Sellers are obligated to

provide such written notice to DNB Bank ASA once the relevant BNDES Parent Company Guarantees are terminated and the Sellers are released

from any obligation and liability in respect thereof.

The

description of and the information set forth under Item 2.03 below is incorporated into this Item 1.01 by reference as if fully set forth

under this item.

Item 2.01 Completion

The

disclosure set forth in the “Introductory Note” above is incorporated into this Item 2.01 by reference. On the Closing Date,

pursuant to the terms and conditions of the Amended and Restated SPA, the Company completed the Transaction in exchange for consideration

consisting of an aggregate purchase price of USD $500 million, on a debt free, cash free basis. The purchase price was subject to customary

adjustments as set forth in the Amended and Restated SPA, including (without limitation) a reduction for the Target Companies’

Closing Date indebtedness (net of cash), capex, transaction costs and other transaction related expenses, and an increase by the excess

of the Target Companies’ Closing Date working capital over a USD $30.1 million target. On the Closing Date, the Tidewater Parties

paid approximately USD $283.1 million in cash and acquired the Target Companies subject to their existing debt totaling approximately

USD $229.3 million, as provided by BNDES and BB. The purchase price remains subject to a customary post-closing adjustment as set forth

in the Amended and Restated SPA. As previously announced, the Tidewater Purchasers incepted into certain warranty and indemnity insurance

policies (collectively, the “W&I Insurance Policy”) in connection with the Transaction allowing for the Tidewater

Purchasers to bring claims for losses arising out of breaches of the warranties and tax covenant, subject to the terms and limitations

set forth in the Amended and Restated SPA. Following the closing of the Transaction, the W&I Insurance Policy will remain in effect

for the duration of the policy terms contained therein.

The

foregoing description of the Amended and Restated SPA and the transactions contemplated thereby are subject to and qualified in their

entirety by reference to the Amended and Restated SPA, which is filed as Exhibit 2.1 hereto, the terms of which are incorporated

Item

2.03

Creation

of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

Banco do Brasil Loan and Replacement

of Parent Company Guarantee

the Closing Date, the Company replaced Remolcadores and its affiliate as the new guarantor of the existing loan (the “BB Loan”)

from BB, as lender, to Magallanes Navegação Brasileira S.A., a wholly owned subsidiary of WSUT (“MNB”),

as borrower. The guarantor replacement was made pursuant to the Fifth Amendment, dated August 18, 2026, to the Fixed Credit Facility

No. 20/00502-4 between BB, MNB, the Company, WSUT, and Wilson Sons Offshore S.A., a wholly owned subsidiary of WSUT (“WSO”),

which became effective as of the consummation of the Transaction upon satisfaction of the conditions specified therein.

The

Fixed Credit Facility No. 20/00502-4 (the “BB Loan Agreement”), executed on December 18, 2008 and as subsequently

amended, provides a secured loan with an interest rate of 3.10% per annum that matures on December 18, 2030. The principal of the

BB Loan amortizes in equal monthly installments of approximately USD $0.4 million, and interest is payable monthly. As of the Closing

Date, the BB Loan had an outstanding principal amount of approximately USD $22.5 million.

The

BB Loan Agreement contains certain customary covenants and events of default. The covenants include, among others: (i) maintaining

a ratio of EBITDA to debt service payments (comprised of principal amortizations and interest) at 1.1 : 1 or higher; (ii) maintaining

an aggregate appraisal value of at least 130% of the outstanding loan balance for vessels serving as collateral; (iii) not changing

the vessels’ primary activities without the lender’s consent; (iv) entering into contracts at market prices; (v) permitting

vessel inspections by the lender; and (vi) complying with environmental law. BB has the right to declare all outstanding installments

immediately due and payable if, among other things, MNB: (i) fails to timely pay any obligation; (ii) fails to pay any other

debt exceeding BRL$500,000 within 30 days after notice; (iii) engages in bankruptcy proceedings; (iv) fails to make timely defense

of legal or tax proceedings; (v) provides incomplete or falsified information to the lender; (vi) fails to disclose material

information; (vii) defaults on another obligation exceeding BRL$500,000; (viii) commits fraud involving the collateral; (ix) fails

to maintain insurance; (x) fails to supplement collateral when required; (xi) fails to make timely defense against any government

assessments; or (xii) undergoes seizure, expropriation or nationalization of assets.

All

obligations under the BB Loan Agreement are guaranteed by the Company and secured by a perfected security interest in four vessels owned

by MNB. As of the Closing Date, as additional security for MNB’s obligations under the BB Loan Agreement, MNB delivered to BB a

bank guarantee issued by Banco Bradesco S.A. in an amount equal to 20% of the outstanding balance.

The

foregoing summary of the BB Loan Agreement is subject to, and qualified in its entirety by, the text of the BB Loan Agreement, a copy

of which will be filed with the Company’s Quarterly Report for Form 10-Q for the quarter ended September 30, 2026.

BNDES

Construction Loans

After

the Closing Date, WSO will maintain the existing loan facilities under the Credit Facility Agreements Nos. 07.2.0417.1, 07.2.0418.1, 10.2.1621.1,

12.2.0433.1, and 12.2.0434.1 (collectively, the “BNDES Construction Loan Agreements” and such loans, the “BNDES

Construction Loans”), entered into between 2007 and 2012 and as amended, by and between BNDES, as lender, WSO, as borrower,

and the Sellers (or their affiliates), as guarantors. These loan facilities were originally created to fund the construction of the borrower’s

vessels and have since remained outstanding after all the vessel construction has been completed.

Each

BNDES Construction Loan Agreement provides for a secured loan facility with an interest rate between 2.64% and 3.43% per annum and a maturity

date that varies between December 2026 and December 2035. The principal of the BNDES Construction Loans currently amortizes

in aggregate monthly installments of approximately USD $2.3 million (subject to reduction as individual loans mature), and interest is

payable monthly. As of the Closing Date, the BNDES Construction Loans had an aggregate outstanding principal amount of approximately USD

$170.1 million.

The

BNDES Construction Loan Agreements contain certain customary covenants, including that WSO must comply with the “Provisions Applicable

to BNDES Contracts” (Disposições Aplicáveis aos Contratos do BNDES, Resoluçăo 665/87).

Among its other obligations (with variations among the loan agreements), WSO must: (i) utilize the loan proceeds within a set period;

(ii) grant BNDES certain rights under the insurance policies for the collateral vessels; (iii) comply with the laws applicable

to persons with disabilities; (iv) offer a training program in the event of workforce reductions; (v) adopt environmental protection,

occupational safety, and occupational health measures; (vi) comply with environmental laws; (vii) demonstrate a domestic content

percentage of at least 60% and engage an audit service to verify local content; and (viii) notify BNDES if any person holding a paid

position at the borrower or any of its owners, controlling shareholders or directors is elected or sworn in as a member of the National

Congress.

Under

the BNDES Construction Loan Agreements (with variations), BNDES has the right to declare all outstanding loan balances immediately due

and payable if, among other things: (i) any provision is included in the borrower’s or its controlling entities’ organizational

documents that restricts the borrower’s growth, access to new markets, or ability to pay its financial obligations under the BNDES

Construction Loans; (ii) the borrower fails to offer a training program in the event of workforce reductions; (iii) a final

and non-appealable judgment holds the borrower liable for certain labor or environmental violations; (iv) the borrower or the guarantor

breaches any of its obligations under the BNDES Construction Loans; (v) the borrower undergoes a change in control without the lender’s

consent; (vi) any judicial proceeding or other event occurs that may affect the guarantee in favor of BNDES; (vii) the borrower

uses the loan proceeds for unallowed purposes; or (viii) any person holding a paid position at the borrower or any of its owners,

controlling shareholders or directors is elected or sworn in as a member of National Congress.

The

obligations under the BNDES Construction Loan Agreements are secured by a perfected security interest in eleven vessels owned by WSO.

The vessels serving as collateral must maintain an aggregate appraisal value equal to at least 110% of the outstanding loan balance for

Credit Facility Agreements Nos. 07.2.0417.1, 07.2.0418.1, 12.2.0433.1, and 12.2.0434.1 and 130% of the outstanding loan balance for Credit

Facility Agreement No. 10.2.1621.1 (such ratio, the “collateral coverage ratio”). The guarantees provided by the

Sellers (or their affiliates) will remain in place after the Closing Date. It is expected that the Company will replace the Sellers (or

their affiliates) as the new guarantor upon finalizing the terms of the Company’s guarantee and the supporting documentation. Upon

the Company becoming the new guarantor and the satisfaction of certain other conditions, the BNDES Construction Loan Agreements will be

amended to, among other things, raise the interest rates to 3.21% for Credit Facility Agreements Nos. 07.2.0417.1, 07.2.0418.1, 12.2.0433.1,

and 12.2.0434.1 and 3.77% for Credit Facility Agreement No. 10.2.1621.1, as well as increase the collateral coverage ratio for all

BNDES Construction Loans to 130%.

The

foregoing summary of the BNDES Construction Loans is subject to, and qualified in its entirety by, the text of the BNDES Construction

Loan Agreements, a copy of which will be filed with the Company’s Quarterly Report for Form 10-Q for the quarter ended September 30,

2026.

BNDES

Conversion & Drydock Loans

After

the Closing Date, WSO and MNB will maintain the existing loan facilities under the Credit Facility Agreements Nos. 22.9.0071.1, 22.9.0087.1,

23.9.0103.1, 24.9.0195.1 and 26.9.0068.1 (collectively, the “BNDES C&D Loan Agreements” and such loans, the “BNDES

C&D Loans”), entered into between December 2022 and July 2026 and as amended, by and between BNDES, as lender,

and WSO or MNB, as applicable, as borrower. These loan facilities were created to finance the engine overhaul, drydocking, modernization

and conversion of the borrowers’ vessels.

Each

BNDES C&D Loan Agreement provides for a loan facility with an interest rate of 3% (or, in the case of Credit Facility Agreement No.

26.9.0068.1, a rate of 2.4%) per annum. Maturity dates vary across the facilities: Credit Facility Agreement Nos. 22.9.0071.1 and 22.9.0087.1

mature between December 2028 and December 2030; Credit Facility Agreement No. 23.9.0103.1 matures between February 2027 and February 2031;

and Credit Facility Agreement No. 24.9.0195.1 matures between January 2028 and January 2035. The principal of the foregoing facilities

currently amortizes in aggregate monthly installments of approximately USD $1.8 million (subject to adjustment as individual loans mature

or additional disbursements are made), and interest is payable monthly. Credit Facility Agreement No. 26.9.0068.1 was entered into in

July 2026 for a total amount of approximately USD $26.8 million, with the initial disbursement scheduled for October 2026 and maturity

dates between July 2032 and July 2035. As of the Closing Date, the BNDES C&D Loans had an aggregate outstanding principal amount of

approximately USD $36.7 million.

The

BNDES C&D Loan Agreements contain certain customary covenants, including that the borrower must comply with the “Provisions

Applicable to BNDES Contracts” (Disposições Aplicáveis aos Contratos do BNDES, Resoluçăo 665/87).

Among its other obligations (with variations among the loan agreements), the borrower must: (i) complete the projects within a set

period; (ii) comply with certain environmental obligations related to the projects and notify BNDES of environmental damages that

may compromise the projects; (iii) notify BNDES of certain lawsuits and proceedings involving the borrower, its affiliates, employees,

agents or representatives, or suppliers essential to the projects; (iv) deliver audited annual financial statements; (v) not

incur indebtedness (subject to exceptions); (vi) not sell or encumber assets (subject to exceptions); (vii) not carry out any

change in control; (viii) notify BNDES if any person holding a paid position at the borrower or any of its owners, controlling shareholders

or directors is elected or sworn in as a member of the National Congress; and (ix) not use the loan proceeds in any country or territory

in violation of sanctions.

Under

the BNDES C&D Loan Agreements (with variations), BNDES has the right to declare all outstanding loan balances immediately due and

payable if, among other things: (i) a final and non-appealable judgment holds the borrower liable for certain labor or environmental

violations; (ii) any of the borrower’s representations is inaccurate; (iii) the borrower engages in bankruptcy proceedings;

(iv) the borrower breaches its obligations relating to the guarantees; (v) the borrower commits any anti-bribery, anti-terrorism,

anti-money laundering, or certain other laws; (vi) any provision is included in the borrower’s or its controlling entities’

organizational documents that restricts the borrower’s growth, access to new markets, or ability to pay its financial obligations

under the BNDES C&D Loans; (vii) the borrower uses the loan proceeds for unallowed purposes; or (viii) any person holding

a paid position at the borrower or any of its owners, controlling shareholders or directors is elected or sworn in as a member of the

National Congress.

The

obligations under the BNDES C&D Loan Agreements are secured by bank guarantees provided by various banks.

The

foregoing summary of the BNDES C&D Loans is subject to, and qualified in its entirety by, the text of the BNDES C&D Loan Agreements,

a copy of which will be filed with the Company’s Quarterly Report for Form 10-Q for the quarter ended September 30, 2026.

accordance with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, the Company notes that certain statements

set forth in this communication are forward-looking statements that reflect its current view with respect to future events and future

financial performance. Forward-looking statements are all statements other than statements of historical fact, including, without limitation,

statements about the Company’s replacement as the guarantor for the BNDES Construction Loans, the expected benefits of the Transaction

and the Company’s ability to integrate the Target Companies’ operations and business successfully. All such forward-looking

statements are subject to risks and uncertainties, many of which are beyond the control of the Company, and our future results of operations

could differ materially from our historical results or current expectations reflected by such forward-looking statements. These risks

and uncertainties include, without limitation: potential adverse reactions or changes to business relationships resulting from the completion

of the Transaction; the effects of disruption to our business; the effects of industry, market, economic, political or regulatory conditions

outside of our control; transaction costs; our ability to achieve the benefits from the Transaction, including the anticipated cash flow

generation and customer relationships; our ability to promptly, efficiently and effectively integrate the vessels into our own operations;

unknown liabilities; and the diversion of management time on integration-related issues. Other important factors that could cause actual

results to differ materially from those in the forward-looking statements include: fluctuations in worldwide energy demand and oil and

gas prices; fleet additions by competitors and industry overcapacity; limited capital resources available to replenish our asset base

as needed, including through acquisitions or vessel construction, and to fund our capital expenditure needs; uncertainty of global financial

market conditions and potential constraints in accessing capital or credit if and when needed with favorable terms, if at all; changes

in decisions and capital spending by customers based on industry expectations for offshore exploration, field development and production;

consolidation of our customer base; loss of a major customer; changing customer demands for vessel specifications, which may make some

of our older vessels technologically obsolete for certain customer projects or in certain markets; rapid technological changes; delays

and other problems associated with vessel maintenance; the continued availability of qualified personnel and our ability to attract and

retain them; the operating risks normally incident to our lines of business, including the potential impact of liquidated counterparties;

our ability to comply with covenants in our indentures and other debt instruments; acts of terrorism and piracy; the impact of regional

or global public health crises or pandemics; the impact of potential information technology, cybersecurity or data security breaches;

integration of acquired businesses and entry into new lines of business; disagreements with our joint venture partners; natural disasters

or significant weather conditions; unsettled political conditions, war, civil unrest and governmental actions, such as expropriation or

enforcement of customs or other laws that are not well developed or consistently enforced; risks associated with our international operations,

including local content, local currency or similar requirements especially in higher political risk countries where we operate; interest

rate and foreign currency fluctuations; labor changes proposed by international conventions; increased regulatory burdens and oversight;

changes in laws governing the taxation of foreign source income; retention of skilled workers; enforcement of laws related to the environment,

labor and foreign corrupt practices; increased global concern, regulation and scrutiny regarding climate change; increased stockholder

activism; the potential liability for remedial actions or assessments under existing or future environmental regulations or litigation;

the effects of asserted and unasserted claims and the extent of available insurance coverage; the resolution of pending legal proceedings;

and other risks and uncertainties detailed in our most recent Form 10-K, Form 10-Qs and Form 8-Ks filed with or furnished

to the Securities and Exchange Commission. If one or more of these or other risks or uncertainties materialize (or the consequences of

any such development changes), or should our underlying assumptions prove incorrect, actual results or outcomes may vary materially from

those reflected in our forward-looking statements. Statements in this communication are made as of the date hereof, and the Company disclaims

any intention or obligation to update publicly or revise such statements, whether as a result of new information, future events or otherwise.

which, were Wilson Sons and/or Ultratug to make an immediate Demand, the amount paid pursuant

to such Demand would be credited to the account(s) of Wilson Sons and/or Ultratug, any

the applicable members of their respective Relevant Seller Groups) in respect of any such

Liability pursuant to Clause 11.9;

LC and the Ultratug Replacement LC (respectively). The Sellers shall promptly provide to

the Purchasers by way of email a copy of any Demand (under and as defined in the Replacement

LCs) that is delivered in accordance with the terms of a Replacement LC. Any delay or failure

to deliver such copy to the Purchasers shall not invalidate the delivery of any Demand. Upon

receipt of the relevant funds from DNB Bank ASA under the applicable Replacement LC, each

of Wilson Sons and Ultratug (as applicable) shall use reasonable endeavours to use such received

funds (to the extent of such funds):

(i) first, to reimburse any amounts in respect

relevant updates on the status of the Target Group’s ongoing commercial relationship

with Petrobras, provided that the discussions at and updates provided at such meetings shall

4.6 For the avoidance of doubt, the Parties

agree that the provisions of Clauses 4.1 and 4.5 and Schedule 3

(Conduct of Business before Completion) shall not be considered as constituting any kind

of premature integration between the activities of the Purchasers and the Target Group.

to be utilised in connection therewith) and the performance of their respective obligations

under Clauses 4.11(B), 4.11(C) or 4.12, in each case, other

Manager”) who shall be:

(A) generally responsible for negotiating

and agreeing on the items set out in Clause 5.2;

of the Separation; and

to discuss (whether in person or otherwise) any aspect of the Separation.

faith) would or is likely to prevent completion of the Separation (or any part of it) occurring

in accordance with the timetable set out in the Separation Plan.

5.5 Wilson Sons and the Purchasers shall each

use commercially reasonable efforts to undertake all activities assigned to each of them

respectively under the Separation Plan and to implement the Separation Plan in all material

respects in accordance with the timetable set out in the Separation Plan, which shall include

using commercially reasonable efforts to replace the current arrangements provided by Wilson

Sons or other members of its Relevant Seller Group with respect to the provision of information

technology services for the Target Group as contemplated by the Separation by establishing

standalone arrangements of the Target Group prior to Completion and/or transferring such

service provision to, and integrating such service provision with the arrangements of, the

Purchasers’ Group following Completion.

5.6 In relation to any aspects of the Separation

that remain to be implemented after Completion, Wilson Sons shall use commercially reasonable

efforts to cooperate and assist the Purchasers with respect to the implementation of the

Separation as soon as reasonably practicable, including following the Completion Date until

such Separation has been implemented and, in any event, for no longer than six (6) months

following Completion. During such period, Wilson Sons and the Purchasers shall ensure that

appropriate access rights (including appropriate access to information, documents, premises

and employees) will be provided to Wilson Sons’ Relevant Seller Group or the Purchasers’

Group (as relevant) to the extent reasonably required in connection with Separation planning

and implementation, provided that the Party granting such access will not be required to

any event, by no later than 15 June 2026 or such other time as may be agreed in writing

(which shall include e-mail) between Wilson Sons and the Purchasers.

Purchasers (acting reasonably) determine that certain transitional services will be required

to be provided following Completion by any member of the Seller’s Relevant Seller Group

to any member of the Target Group (“Contingency Transitional Services”),

then it may request that Wilson Sons and the Brazil Target Company enter into the Contingency

Transitional Services Agreement at Completion (a “Contingency TSA Notice”)

detailing the scope and duration of the Contingency Transitional Services that it reasonably

believes will be required by the Target Group following Completion, and following delivery

of such Contingency TSA Notice to the Sellers in accordance with Clause 20:

Transitional Services Agreement, duly executed by Wilson Sons and Brazil Target Company;

members of the Target Group following Completion under the Contingency Transitional Services

Agreement;

its Relevant Seller Group shall, use all reasonable endeavours to identify and obtain by

Completion all permissions, consents, agreements or authorisations from any third party service

provider necessary for the provision of any of the Contingency Transitional Services; and

Purchasers cannot, before the Completion Date, agree on the scope, duration and pricing of

any of the Contingency Transitional Services to be provided, including the fees to be paid

by the Brazil Target Company under the Contingency Transitional Services Agreement or any

other material terms, then, subject to the Sellers obtaining all permissions, consents, agreements

or authorisations from any third party service provider necessary for the provision of any

of the Contingency Transitional Services, the scope of any such Contingency Transitional

Services shall be deemed to be the same, in all material respects, as the equivalent service

provided by Wilson Sons’ Relevant Seller Group to the Target Group during the period

of twelve (12) months (or such shorter period in which the existing service was provided,

if less than twelve (12) months) prior to the Completion Date, except that fees to be paid

Days, be referred to a senior manager of each of Wilson Sons and the Purchasers for determination.

In the event that the senior managers cannot resolve such dispute or difference within ten

(10) Business Days, the dispute or difference shall be referred to the Chief Financial

Officers of Wilson Sons and the Purchasers. In the event that the Chief Financial Officers

cannot resolve such dispute or difference within ten (10) Business Days, the Parties

shall not be under an obligation to enter into mediation or formal dispute resolution procedures.

of any member of the Purchasers’ Group is expressly contemplated in connection with

Purchasers undertake to act, and to use all reasonable endeavours to procure that each other

relevant member of the Purchasers’ Group acts, reasonably and in good faith in connection

therewith.

with the implementation of the Separation by any member of Wilson Sons’ Relevant Seller

in the Separation, the Parties will use reasonable efforts to have such third parties engaged

by the Purchasers and, if such third parties are engaged by the Sellers, the Purchasers must

consent to any scope of work and fee structure in advance. For the avoidance of doubt, each

Party shall bear its own costs in connection with the negotiation and agreement of (x) the

Separation Plan and (y) the form and terms of the Contingency Transitional Services

Agreement. The Purchasers shall, promptly at the written request of Wilson Sons or any Target

Company, which request shall include an itemised list of the relevant costs and identify

or such Target Company (on its own behalf and as trustee for each other member of the Target

Group) on an after-Tax basis for all such costs to be borne by the Purchasers pursuant to

this Clause 5.11 to the extent such costs are incurred by any member of Wilson

Sons’ Relevant Seller Group or the Target Group.

Period being a “Transition Period”), solely in a manner and to an extent

that is substantially consistent with their use and display in the conduct of the business

of the Target Companies during the six (6) months immediately prior to the Completion

Date (and any natural evolutions or extensions of such use in the business of the Target

Companies).

(D) The Purchasers and the Target Group shall

use the Restricted Names at a level of quality consistent in all material respects to that

in effect for the Restricted Names used in the business of the Target Companies during the

six (6) months immediately prior to the Completion Date.

Assurances

11.8 The Purchasers undertake to the Sellers

that they shall use all reasonable endeavours, and take any such action as any Seller may

reasonably request, to obtain the removal or replacement of, and the release of any obligations

of such Seller or any member of its Relevant Seller Group under, any Assurances given or

procured by any member of its Relevant Seller Group to or for the benefit of any person who

is not a member of such Relevant Seller Group in connection with the business of the Target

Group with effect from Completion (or, where the Purchasers are unable to procure such removal

or replacement, and release, with effect from Completion, as soon as reasonably practicable

thereafter), and any such removal or replacement, and release, shall in each case be on a

non-recourse basis to any member of either Relevant Seller Group.

11.9 Pending such removal or replacement,

and release, the Purchasers shall:

(A) indemnify, on an after-Tax basis, each

Seller and any other member of such Seller’s Relevant Seller Group in respect of any

Losses suffered or incurred after Completion by that Seller or any other member of such Seller’s

Relevant Seller Group in any way pursuant to or in connection with any such Assurance; and

(B) not enter into any variation of any agreement

which may have the effect of varying any such Assurance in a way which is materially adverse

to any member of a Seller’s Relevant Seller Group without the prior written consent

of the relevant Seller.

Insurances

11.10 The Purchasers acknowledge and agree

that each Seller shall be entitled to arrange for all insurance policies provided or arranged

by its Relevant Seller Group in relation to the business of the Target Group (whether under

policies maintained with third party issuers or other members of its Relevant Seller Group)

prior to or at Completion (such policies collectively, the “Seller Insurance

Policies”) to cease upon Completion in respect of any occurrence, event, act, omission

or other matter relating to any member of the Target Group or the business of the Target

Group occurring or existing on or after Completion.

11.11 Subject to Clause 11.12, the

Purchasers further acknowledge and agree that:

(A) neither they, nor any other member of

the Purchasers’ Group, shall have or be entitled to the benefit of, nor shall it or

they make or notify any claim under, any Seller Insurance Policies in respect of any occurrence,

event, act, omission or other matter relating to any member of the Target Group or the business

of the Target Group occurring or existing on or after Completion; and

(B) it shall be the sole responsibility of

the Purchasers to ensure that, with effect from Completion, adequate insurance cover (including

any insurance cover required pursuant to applicable Law or the terms of any contract to which

any member of the Target Group is party) is put in place with respect to the business of

the Target Group.

11.12 Notwithstanding Clauses 11.10

and 11.11 and without prejudice to Clause 6.2(A):

(A) to the extent that, following Completion,

any member of the Target Group has any claim under any Seller Insurance Policy (excluding

any Relevant Insurance Claim in respect of which Clause 6.2(A) applies), and

if and to the extent that such claim would remain valid following Completion, then each Seller

shall ensure that the relevant members of its Relevant Seller Group shall (in each case,

subject to, and where permitted by, the terms of the relevant Seller Insurance Policy):

(i) provide to the Purchasers and the relevant

member of the Target Group such reasonable assistance and cooperation as the Purchasers or

the relevant member of the Target Group may reasonably request in order to allow such member

of the Target Group to pursue or continue to pursue such claim and to continue to have the

benefit of such Seller Insurance Policy, provided that the Purchasers shall be responsible

for any reasonable costs and expenses incurred by any Seller and the members of its Relevant

Seller Group in providing such assistance and cooperation;

(ii) subject to the Purchasers indemnifying,

on an after-Tax basis, each Seller and the other members of its Relevant Seller Group for

any reasonable costs, Liabilities and expenses incurred by any member of such Seller’s

Relevant Seller Group in making a claim under the relevant Seller Insurance Policy, make

and pursue such claim under such Seller Insurance Policy as the Purchasers or the relevant

member of the Target Group shall reasonably request and keep the Purchasers and the relevant

member of the Target Group reasonably informed of the progress of such claim, provided that

no Seller nor any other member of a Seller’s Relevant Seller Group shall be obliged

to take any action (or omit or desist from taking any action) which would reasonably be expected

to be materially detrimental to any Seller and/or its Relevant Seller Group, provided, further,

that if any Seller or any member of its Relevant Seller Group, on the one hand, and any member

of the Target Group, on the other hand, have competing claims under a Seller Insurance Policy

and there are insufficient limits remaining under such Seller Insurance Policy, then such

limits shall be allocated pro rata among such parties in accordance with their respective

bona fide losses covered thereunder (it being acknowledged that the Target Group’s

bona fide losses will relate to claims in respect of occurrences, events, acts, omissions

or other matters relating to any member of the Target Group or the business of the Target

Group occurring or existing at or prior to Completion only); and

(iii) promptly remit, by wire transfer of

immediately available funds, upon receipt any insurance proceeds (net of any Taxes) relating

to any such claim to the Purchasers or the relevant member of the Target Group.

Transaction Costs

11.13 The Purchasers undertake to the Sellers

that they shall procure that each relevant member of the Target Group shall pay any Transaction

Costs which remain payable by it on or after the Completion Date (provided such Transaction

Costs are included in the Transaction Costs Amount) either: (A) as soon as reasonably

practicable following Completion and, in any event, within five (5) Business Days of

the Completion Date; or (B) at such later date as may be expressly agreed in writing

between the relevant member of the Target Group and the relevant third party.

ANTAQ Notifications

11.14 The Purchasers shall procure that, as

soon as reasonably practicable following Completion and, in any event, within thirty (30)

days of the Completion Date, each of the following Affiliates notifies ANTAQ that Completion

has occurred (in each case in accordance with all applicable Law, regulations and ANTAQ requirements

relating to such notifications):

(A) Wilson, Sons Offshore S.A.; and

(B) Magallanes Navegação Brasileira

S.A.

12. Payments, Withholdings and Deductions

12.1 Unless otherwise expressly set out in

this Agreement or agreed in writing between the Sellers and the Purchasers, all payments

to be made under this Agreement shall be made by way of electronic transfer in US dollars

in immediately available same-day funds, provided, however, that if any such amount comprising

the Consideration is payable to any person in Brazil, it must be converted into Brazilian

reais (R$) at the Completion Exchange Rate or Post-Completion Adjustment Exchange Rate, as

the case may be.

12.2 Save in respect of the payment of the

Consideration or in the case of a payment being made on an after-Tax basis where such deduction

or withholding has already been taken into account in calculating the amount of the payment:

(A) all payments made by any Party under this

Agreement shall be made gross, free of any deduction or withholding of any kind other than

any deduction or withholding required by applicable Law; and

(B) if a Party (“withholding payor”)

is required by applicable Law to make a deduction or withholding from a payment to another

Party or person (the “withholding payee”) under this Agreement (other

than a payment of any part of the Consideration, any amount in respect of the Retention Amount,

and any payment of interest), the amount payable shall be increased to the extent necessary

to ensure that, after the making of any deduction or withholding, the withholding payee receives

a sum equal to the sum it would have received had no deduction or withholding been made.

Amounts deducted and withheld and remitted to the appropriate Tax Authority in accordance

with applicable Law shall be treated as paid to the person in respect of whom such deduction

or withholding was made.

Completion BWT Amount

12.3 Notwithstanding anything to the contrary

in Clause 12.2, the Purchasers shall:

(A) withhold from the payment of Ultratug’s

Relevant Proportion of the Completion Payment and pay to the relevant Brazilian Governmental

Authorities on the Completion Date the applicable BWT, in the amount calculated by Ultratug

pursuant to Clause 12.4 (and having taken into account the Completion Exchange

Rate for the purposes of finalising such calculation) (the “Completion BWT Amount”);

and

(B) deliver to Ultratug a copy of the BWT

receipt (Documento de Arrecadação de Receitas Federais – DARF)

promptly, and in any event within two (2) Business Days, following the payment by the

Purchasers of the Completion BWT Amount in accordance with applicable Brazilian Law.

For the avoidance of doubt, the payment

by the Purchasers to Ultratug of its Relevant Completion Payment Amount in accordance with paragraph 2.2 of Schedule 2

(Completion and Post-Completion Arrangements) already takes into account the BWT withholding to be made by the Purchasers pursuant to

Clause 12.3(A), and the Purchasers shall not make any additional withholding or deduction from the payment of Ultratug’s

Relevant Completion Payment Amount unless otherwise required by applicable Law.

12.4 Ultratug shall calculate the applicable

BWT payable by the Purchasers pursuant to Clause 12.3(A) in good faith (converting,

for these purposes, Ultratug’s Relevant Proportion of the Completion Payment from US

dollars (USD) to Brazilian reais (R$) as at the Applicable Exchange Rate for the purposes

of the date such calculations are made) according to applicable Brazilian Law, based on the

difference between the Completion Payment and the acquisition cost originally incurred in

Brazilian reais (R$) (considering the foreign exchange rates of the time of the acquisition,

the subscription or capitalization of profits permitted by Law) by Ultratug in acquiring

or subscribing for (as applicable) the Ultratug Brazil Target Shares (“Ultratug

Acquisition Cost”), and shall:

(A) provide to the Purchasers a draft of such

calculation (which, for the avoidance of doubt, shall be subject to Ultratug’s Relevant

Proportion of the Completion Payment being converted to Brazilian reais (R$) at the Completion

Exchange Rate) by no later than the date falling three (3) Business Days prior to the

Completion Date;

(B) take into account any reasonable comments

(acting in good faith) on such draft calculation of the applicable BWT provided by the Purchasers

to Ultratug by no later than the date falling two (2) Business Days prior to the Completion

Date; and

of such calculation (which, for the avoidance of doubt, shall be subject to Ultratug’s

Relevant Proportion of the Completion Payment being converted to Brazilian reais (R$) at

the Completion Exchange Rate) by no later than the date falling one (1) Business Day

prior to the Completion Date.

Post-Completion Adjustment BWT Amount

12.5 In the event that following delivery

of the Completion Statement in accordance with paragraph 2 of Part A

of Schedule 8 (Post-Completion Adjustment) the Purchasers are required to make an

Ultratug Post-Completion Gross Adjustment Payment to Ultratug pursuant to paragraph 3.9(A)(iii)(a) or

paragraph 3.9(B)(iii) of Part A of Schedule 8 (Post-Completion

Adjustment) (as relevant), the Purchasers shall:

(A) withhold from the payment of such Ultratug

Post-Completion Gross Adjustment Payment and pay to the relevant Brazilian Governmental Authorities

on the Post-Completion Adjustment Payment Date the applicable BWT in the amount calculated

by Ultratug pursuant to Clause 12.7 (and having taken into account the Post-Completion

Adjustment Exchange Rate for the purposes of finalising such calculation) (the “Post-Completion

Adjustment BWT Amount”); and

(B) deliver to Ultratug a copy of the BWT

receipt (Documento de Arrecadação de Receitas Federais – DARF)

promptly, and in any event within two (2) Business Days, following the payment by the

Purchasers of the Post-Completion Adjustment BWT Amount in accordance with applicable Brazilian

Law.

For the avoidance of doubt, the payment

by the Purchasers to Ultratug of the Ultratug Post-Completion Net Adjustment Payment in accordance with paragraph 3.9(A)(iii)(a) or

paragraph 3.9(B)(iii) (as relevant) of Part A of Schedule 8 already takes into account the BWT withholding

to be made by the Purchasers pursuant to Clause 12.6(A) and the Purchasers shall not make any additional withholding or deduction

from the payment of the Ultratug Post-Completion Net Adjustment Payment unless otherwise required by applicable Law.

12.6 In the event that, following Completion,

the Purchasers are required to make a payment to Ultratug pursuant to Clause 6.2(A)(vi),

Clause 6.6 or Schedule 11 (Petrobras Claim) (as relevant) (each, an “Ultratug

Post-Completion Payment”), the Purchasers shall:

(A) withhold from the payment of such Ultratug

Post-Completion Payment and pay to the relevant Brazilian Governmental Authorities on the

date of the relevant Ultratug Post-Completion Payment the applicable BWT, in the amount calculated

by Ultratug pursuant to Clause 12.7 (and having taken into account the Ultratug

Post-Completion Exchange Rate for the purposes of finalising such calculation) (the “Ultratug

Post-Completion BWT Amount”); and

(B) deliver to Ultratug a copy of the BWT

receipt (Documento de Arrecadação de Receitas Federais – DARF)

promptly, and in any event within two (2) Business Days, following the payment by the

Purchasers of the Ultratug Post-Completion Payment in accordance with applicable Brazilian

Law.

12.7 Ultratug shall calculate the applicable

BWT payable by the Purchasers pursuant to Clause 12.5(A) and, if applicable,

Clause 12.6(A) in good faith (converting, for these purposes, the relevant Ultratug

Post-Completion Gross Adjustment Payment or Ultratug Post-Completion Payment (as applicable)

from US dollars (USD) to Brazilian reais (R$) as at the Applicable Exchange Rate for the

purposes of the date such calculations are made) according to applicable Brazilian Law and,

in the case of an Ultratug Post-Completion Gross Adjustment Payment, based on the difference

between the Ultratug Post-Completion Gross Adjustment Payment and the Ultratug Acquisition

Cost (taking into account the prior payment of Ultratug’s Relevant Proportion of the

Completion Payment and, if applicable, any Ultratug Post-Completion Gross Adjustment Payment

and any prior Ultratug Post-Completion Payment). Furthermore, Ultratug shall:

(A) provide to the Purchasers a draft of such

calculation (which, for the avoidance of doubt, shall be subject to the Ultratug Post-Completion

Gross Adjustment Payment or relevant Ultratug Post-Completion Payment (as applicable) being

converted to Brazilian reais (R$) at the Post-Completion Adjustment Exchange Rate or Ultratug

Post-Completion Exchange Rate (as applicable)) by no later than the date falling three (3) Business

Days prior to the Post-Completion Adjustment Payment Date or Ultratug Post-Completion Payment

Date (as applicable);

(B) take into account any reasonable comments

(acting in good faith) on such draft calculation of the applicable BWT provided by the Purchasers

to Ultratug by no later than the date falling two (2) Business Days prior to the Post-Completion

Adjustment Payment Date or Ultratug Post-Completion Payment Date (as applicable); and

of such calculation (which, for the avoidance of doubt, shall be subject to the Ultratug

Post-Completion Gross Adjustment Payment or Ultratug Post-Completion Payment (as applicable)

being converted to Brazilian reais (R$) at the Post-Completion Adjustment Exchange Rate or

Ultratug Post-Completion Exchange Rate (as applicable)) by no later than the date falling

one (1) Business Day prior to the Post-Completion Adjustment Payment Date or Ultratug

Post-Completion Payment Date (as applicable).

BWT indemnity

12.8 Subject to the Purchasers complying in

all material respects with its obligations with respect to timely payment of applicable BWT

(including pursuant to Clauses 12.3, 12.5 and 12.6 and to paragraph 4

of Schedule 6), except where such failure to so comply results from, or is caused

by, any act or omission of Ultratug or any other Seller or their respective Affiliates (including

any delay or failure by the Sellers to comply with its own obligations pursuant to Clauses

12.4 and 12.7), Ultratug hereby agrees and undertakes to hold the Purchasers (and any

individual acting as legal representative of the Purchasers for Brazilian Tax Law purposes

in connection with the Transaction) harmless and indemnify on an after-Tax basis such persons

from and against any and all Losses (excluding, for the avoidance of doubt, the applicable

amount of the BWT itself) incurred by them as a result of, or in connection with, its payment

of the BWT applicable to the Transaction pursuant to this Agreement (including as a result

of any error in Ultratug’s calculation of such BWT in accordance with Clause 12.4

or Clause 12.5 regardless of any limitations set forth in this Agreement). To

the extent that the Purchasers (or any individual acting as legal representative of the Purchasers

for Brazilian Tax Law purposes in connection with the Transaction) are required to post any

bond, guarantee or surety in connection with any claim, demand, investigation or assessment

initiated by the Brazilian Tax Authorities with the purpose of disputing the calculation

and withholding the BWT, Ultratug shall take all actions that may be reasonably required

to secure the timely and full posting of any such bond, guarantee or surety on behalf of

the Purchasers (and any individual acting as legal representative of the Purchasers for Brazilian

Tax Law purposes in connection with the Transaction).

Refund of BWT

12.9 The Purchasers undertake to Ultratug

that, in the event that following delivery of the Completion Statement in accordance with

paragraph 2 of Part A of Schedule 8 (Post-Completion Adjustment)

the Adjustment Amount is a negative number and Ultratug’s Relevant Proportion of the

Adjustment Amount (expressed as a positive number) is greater than the Retention Amount (as

at the Post-Completion Adjustment Payment Date), or in any other circumstances resulting

in a reduction, or deemed reduction, in the amount of the Consideration received, or deemed

received, by Ultratug under this Agreement (including, without limitation, pursuant to Clause

6.2(B) if applicable), they shall:

(A) use commercially reasonable efforts to

co-operate with Ultratug in good faith and procure that each relevant member of the Target

Group so co-operates with Ultratug in good faith, in connection with obtaining a refund of

any overpayment of BWT from the relevant Brazilian Governmental Authorities; and

(B) provide, and use all reasonable endeavours

to procure that each relevant member of the Target Group provides, such assistance and information

as may be reasonably requested by Ultratug in connection with obtaining a refund of any overpayment

of BWT from the relevant Brazilian Governmental Authorities.

All out-of-pocket fees, costs and expenses

incurred by the Purchasers in connection with their obligations pursuant to this Clause 12.9 shall be borne by Ultratug.

13. Purchasers’ Guarantee

13.1 In consideration of the Sellers agreeing

to sell the Target Shares on the terms set out in this Agreement, the Purchasers’ Guarantor

irrevocably and unconditionally:

(A) guarantees to the Sellers the due and

punctual performance of each obligation, commitment and undertaking of the Purchasers (on

behalf of itself and/or any member of the Purchasers’ Group) contained in this Agreement

or the Transaction Documents; and

(B) agrees to indemnify the Sellers on an

after-Tax basis in respect of any breach of the Purchasers (on behalf of themselves and/or

any member of the Purchasers’ Group) of any of its obligations, commitments and undertakings

contained in this Agreement or the Transaction Documents.

13.2 The liability of the Purchasers’

Guarantor contained in this Agreement and the Transaction Documents shall not be released

or diminished by any variation of the terms of this Agreement or any Transaction Document

(whether or not agreed by the Purchasers’ Guarantor) any forbearance, neglect or delay

in seeking performance of the obligations hereby imposed or any granting of time for such

performance.

13.3 If the Purchasers default for any reason

whatsoever in the performance of any obligation, commitment or undertaking undertaken or

expressed to be undertaken under or pursuant to this Agreement or any other document referred

to in it, the Purchasers’ Guarantor shall forthwith upon demand unconditionally perform

(or procure performance of) and satisfy (or procure the satisfaction of) the obligation,

commitment or undertaking in regard to which such default has been made in the manner prescribed

by this Agreement and the Transaction Documents so that the same benefits shall be conferred

on the Sellers as would have been received if such obligation, commitment or undertaking

had been duly performed and satisfied by the Purchasers in accordance with the terms of this

Agreement and the Transaction Documents (as applicable).

13.4 The Purchasers’ Guarantor shall

be liable only to the same extent as the Purchasers would be liable under this Agreement

and shall be entitled to assert any defences, limitations of liability, exclusions, set-offs

and any other rights available to the Purchasers under this Agreement. The aggregate liability

of the Purchasers’ Guarantor under Clause 13.1(A) shall in no event exceed

the aggregate liability that the Purchasers would have to the Sellers under this Agreement.

13.5 This guarantee is to be a continuing

guarantee and accordingly is to remain in force until all the obligations of the Purchasers

(in respect of itself and on behalf of the Purchasers’ Group) shall have been performed

or satisfied regardless of the legality, validity or enforceability of any provisions of

this Agreement or the Transaction Documents and notwithstanding the winding-up, liquidation,

dissolution or other incapacity of the Purchasers or any change in the status, control or

ownership of the Purchasers. This guarantee is in addition to, without limiting and not in

substitution for, any rights or security which the Sellers may now or after the date of this

Agreement have or hold for the performance and observance of the obligations, commitments

and undertakings of the Purchasers under or in connection with this Agreement or any other

document referred to in it.

13.6 The Purchasers’ Guarantor agrees

that any obligation, commitment or undertaking undertaken or expressed to be undertaken by

the Purchasers (including, without limitation, any monies expressed to be payable under this

Agreement) which may not be enforceable against or recoverable from the Purchasers by reason

of any legal limitation, disability or incapacity on or of the Purchasers or any fact or

circumstance (other than any limitation imposed by this Agreement) shall nevertheless be

enforceable against and recoverable from the Purchasers’ Guarantor as though the same

had been incurred by the Purchasers’ Guarantor and the Purchasers’ Guarantor

were the sole or principal obligor in respect thereof and shall be performed or paid by the

Purchasers’ Guarantor on demand.

14. Access

14.1 The Sellers shall, and shall procure

that the Target Group shall, afford to the Purchasers’ Group and to the officers, employees,

accountants, consultants, legal counsel, financial advisors and agents and other representatives

(collectively, “Representatives”) of the Purchasers’ Group reasonable

access during normal business hours, throughout the Interim Period, to the Target Group and

its books, records, work papers and personnel, as the Purchasers may reasonably request in

connection with activities related to the implementation of the Transaction (collectively,

the “Activities”). Notwithstanding the foregoing, neither the Sellers

nor the Target Group shall be required to afford such access if it would unreasonably disrupt

the operations of such party or any of its Subsidiaries, would cause a violation of any Contract

or obligation of confidentiality to which such party or any of its Subsidiaries is a party

(provided that Sellers and/or the Target Group, as the case may be, has used its reasonable

efforts to find an alternative way to provide the access or information contemplated by this

Clause 14.1), cause a risk of a loss of privilege to such party or any of its Subsidiaries

or would constitute a violation of any applicable Law. The Purchasers’ Group shall,

and shall cause their respective Representatives to, observe and comply with all bona fide

health, safety and security rules, regulations, requirements and instructions of the Target

Group, and the terms and conditions of the Confidentiality Agreement.

14.2 For a period of seven (7) years

from Completion, to the extent permitted by applicable Law, the Purchasers shall make available

to each Seller and each other member of its Relevant Seller Group any Books and Records of

any member of the Target Group (or, if practicable, the relevant parts of those Books and

Records) which are reasonably required by that Seller or any other member of its Relevant

Seller Group for the purpose of dealing with its Tax, accounting and insurance affairs and/or

compliance with any legal, regulatory or statutory duty and/or its obligations under the

Transaction Documents and, accordingly, the Purchasers shall, upon being given reasonable

notice by the relevant Seller or, as the case may be, the relevant other member of its Relevant

Seller Group and subject to the relevant Seller or, as the case may be, the relevant other

member of its Relevant Seller Group giving such undertaking as to confidentiality as the

Purchasers shall reasonably require, procure that such Books and Records are made available

to the relevant Seller or, as the case may be, the relevant other member of its Relevant

Seller Group for inspection (during Working Hours) and copying (at the expense of the relevant

Seller or, as the case may be, the relevant other member of its Relevant Seller Group) only

to the extent necessary for such purpose.

14.3 For a period of seven (7) years

from Completion, to the extent permitted by applicable Law, each Seller shall, and shall

procure that each other member of its Relevant Seller Group shall, make available to each

member of the Purchasers’ Group any Books and Records of any member of the Relevant

Seller Group (or, if practicable, the relevant parts of those Books and Records) which are

reasonably required by any member of the Purchasers’ Group for the purpose of dealing

with its Tax, accounting and insurance affairs and/or compliance with any legal, regulatory

or statutory duty and/or its obligations under the Transaction Documents and, accordingly,

the relevant Seller shall, upon being given reasonable notice by the member of the Purchasers’

Group and subject to the relevant member of the Purchasers’ Group giving such undertaking

as to confidentiality as the relevant Seller shall reasonably require, procure that such

Books and Records are made available to the relevant member of the Purchasers’ Group

for inspection (during Working Hours) and copying (at the relevant member of the Purchasers’

Group’s expense) only to the extent necessary for such purpose.

15. Remedies and Waivers

15.1 Unless expressly indicated otherwise

in this Agreement, no delay or omission on the part of any Party in exercising any right,

power or remedy provided by Law or under this Agreement or any other documents referred to

in it shall impair such right, power or remedy or operate as a waiver thereof.

15.2 The single or partial exercise of any

right, power or remedy provided by Law or under this Agreement shall not preclude any other

or further exercise thereof or the exercise of any other right, power or remedy except where

expressly stated herein.

15.3 The rights, powers and remedies provided

in this Agreement are cumulative and not exclusive of any rights, powers and remedies provided

by Law unless otherwise expressly stated herein.

16. Binding Effect; Assignment

16.1 This Agreement shall be binding upon

and shall inure to the benefit of the Parties and their permitted successors and assigns.

Except as otherwise expressly stated in the applicable Transaction Document, no Party shall

under this Agreement or any of the other Transaction Documents (together with any causes

of Action arising in connection with any of them) without the prior written consent of the

Sellers (in the case of assignment by the Purchasers) or the Purchasers (in the case of assignment

by any of the Sellers), which any such Party/ies may withhold in its/their absolute discretion.

16.2 Notwithstanding anything to the contrary

herein, no consent shall be required in the case of an assignment:

(A) by the Purchasers in whole or in part

to any other member of the Purchasers’ Group; and

(B) by any Seller to any other member of its

Relevant Seller Group,

provided that, in each case, where

any such assignment takes place:

(i) there shall be no adverse impact on the

other Parties;

(ii) such assignment would not reasonably

be expected to result in any delay to the satisfaction of any of the Conditions or the implementation

of the Separation; and

(iii) the liabilities of the other Parties

under the relevant Transaction Document or this Agreement shall be no greater than such liabilities

would have been had the assignment not occurred.

16.3 Any purported assignment in violation

of this Clause 16 shall be void.

16.4 Except as otherwise expressly stated

in the applicable Transaction Document, no Party shall make a declaration of trust in respect

of or enter into any arrangement whereby it agrees to hold in trust for any other person

all or any part of the benefit of, or its rights or benefits under, the Transaction Documents.

16.5 Except as otherwise expressly stated

in the applicable Transaction Document, no Party shall subcontract or enter into any arrangement

whereby another person is to perform any or all of its obligations under the Transaction

Documents.

17. Further Assurance

Without prejudice to any restriction

or limitation on the extent of any Party’s obligations under this Agreement, each of the Parties shall from time to time, so far

as each is reasonably able, do or procure the doing of all such acts and/or execute or procure the execution of all such documents in

a form reasonably satisfactory to the Party concerned as they may reasonably consider necessary to transfer the Target Shares to the

Purchasers or otherwise to give the other Parties the full benefit of this Agreement.

18. Entire Agreement

18.1 This Agreement, the Transaction Documents

and any other documents entered into pursuant to this Agreement or the Transaction Documents

constitute the whole and only agreement between the Parties relating to the sale and purchase

of the Target Shares.

18.2 Each Party acknowledges that in entering

into this Agreement, the Transaction Documents and any other documents entered into pursuant

to this Agreement or the Transaction Documents it is not relying on and has not been induced

to enter into this Agreement, the Transaction Documents or any other such document on the

basis of any draft, agreement, undertaking, representation, warranty, promise, assurance

or arrangement of any nature whatsoever, whether or not in writing, relating to the subject

matter of the Transaction Documents made or given by any person at any time prior to the

date of this Agreement (a “Pre-contractual Statement”) except as expressly

set out in this Agreement.

shall have any right of Action against any other Party arising out of or in connection with

any Pre-contractual Statement except to the extent that is expressly set out in this Agreement

or any other such document.

in the Transaction Documents, if there is any conflict between the terms of this Agreement

and any other Transaction Documents, this Agreement shall prevail (as between the Parties

to this Agreement and as between any members of each Seller’s Relevant Seller Group

on the one hand and any members of the Purchasers’ Group on the other).

18.5 This Agreement may only be varied, supplemented

or replaced by a document signed by each of the Parties and expressed to be a variation to

this Agreement.

19. Rights of Third Parties

19.1 Unless this Agreement expressly states

otherwise (which includes any provision expressed to be in favour of any person who is not

a Party, including Clauses 4.11(C), 4.11(D), 4.11(E), 4.14, 5.5,

9.4, 10.4, 11.9, 11.12, 12.8, 23.2, 23.3,

32.1 The Purchasers have procured, with a

(the Primary Policy and the Excess Policy collectively being the “W&I Insurance

Policy”) which take effect simultaneously on or prior to Completion.

except in the case of fraud, the Purchasers’ sole remedy in respect of any Claim in

respect of the Warranties (other than, subject to paragraphs 2.7 to 2.10

Warranty and any Tax Claim) is a claim against the W&I Insurance Policy.

32.3 For the avoidance of doubt, any non-payment

under the W&I Insurance Policy, any defect, invalidity, illegality, unenforceability,

expiry, termination or repudiation of the W&I Insurance Policy, any incapacity, insolvency

or other legal limitation of the insurer(s) providing the W&I Insurance Policy,

any insufficiency or inadequacy of cover in respect of the W&I Insurance Policy or any

failure by the Purchasers to effect or bind the W&I Insurance Policy shall not affect

the limitations on the Sellers’ Liability set out in Clause 10 and Schedule

6 (Limitations on Liability).

32.4 The Purchasers shall ensure that such

W&I Insurance Policy provides that (and that such terms shall not be amended, waived

or otherwise modified in any manner inconsistent with this Clause 32.4 without

the prior written consent of the Sellers):

waives and agrees not to pursue, directly or indirectly, any and all rights of subrogation,

contribution or any other rights that the insurer(s) might have against the Sellers,

any of their Affiliates and any direct and indirect equityholders, directors, members, managers,

partners and Representatives of any of the foregoing (collectively, the “Seller

Related Parties”), except in the case of fraud by any such Seller Related Party;

and

(B) the Seller Related Parties are express

third party beneficiaries of the waiver contained in Clause 32.4(A) and are entitled

to enforce such waiver against the insurer(s).

32.5 If any amount recovered under the W&I

Insurance Policy in respect of a breach of a Fundamental Warranty or in respect of any Tax

Claim is subject to Tax in the hands of the Purchasers, to the extent such Tax is not recoverable

under the W&I Insurance Policy due to the limit of liability under the W&I Insurance

Policy being exceeded, subject to applicable limitations and exclusions in this Agreement

(including the Tax Covenant), such amount of Tax shall be considered a Loss in respect of

a breach of the relevant Fundamental Warranty or Tax Warranty or a Loss that is the subject

of a Tax Covenant Claim (as the case may be), and the Purchasers shall be entitled to make

a Claim against the Sellers in respect of such amount of Tax notwithstanding Clause 32.2

above, but only to the extent that such Tax would have been recoverable by the Purchasers

if, but for the existence of, and provisions of this Agreement relating to, the W&I Insurance

Policy, the Purchasers had made the relevant Claim for breach of Fundamental Warranty or

Tax Claim against the Sellers directly.

32.6 At the written request of any Seller,

the Purchasers shall, without limitation to any right of any Seller separately to enforce

such terms, use reasonable endeavours (at the Sellers’ expense) to enforce any term

in the W&I Insurance Policy under which the insurer thereunder waives its rights to take

subrogated action against any Seller Related Parties upon the terms set out in the W&I

Insurance Policy.

32.7 The Purchasers shall be solely responsible

for all premiums and underwriting fees under the W&I Insurance Policy and any and all

Policy.

W&I Insurance Policy

2.7 The Purchasers confirm that the Cayman

Purchaser (on its own behalf and for the benefit of the Brazil Purchaser) has entered into

the W&I Insurance Policy prior to or as of signing of this Agreement. The Parties acknowledge

and agree that, except in the case of fraud, the Purchasers’ sole remedy in respect

of any Claim in respect of the Warranties (other than, subject to paragraphs 2.7 to

2.10 (inclusive) of this Schedule 6, Claims in respect of any Fundamental Warranty

and any Tax Claim) is a claim against the W&I Insurance Policy.

2.8 No Fundamental Warranty Claim or Tax Claim

shall be brought against any Seller, and no Seller shall be liable for any Fundamental Warranty

Claim or Tax Claim, unless and until the Cayman Purchaser (on its own behalf and/or for the

benefit of the Brazil Purchaser) has made any claim it may have under the W&I Insurance

Policy and (subject to paragraph 2.9 below) used best endeavours to pursue such claim.

Each Seller’s Relevant Proportion of Liability in respect of such Fundamental Warranty

Claim or Tax Claim (as applicable) shall be reduced (on a pro rata basis) by the amount (if

any) recovered under the W&I Insurance Policy (less the reasonable costs of recovery

actually incurred by the Purchasers in pursuing such claim under the W&I Insurance Policy),

or extinguished if the amount so recovered is equal to or exceeds the amount of the Fundamental

Warranty Claim or Tax Claim (as applicable).

2.9 Subject to paragraph 2.10 below,

where the Cayman Purchaser (on its own behalf and/or for the benefit of the Brazil Purchaser)

has made a claim under the W&I Insurance Policy in respect of a Fundamental Warranty

Claim or a Tax Claim and it has used best endeavours to pursue such claim but such claim

under the W&I Insurance Policy has not been settled or finally determined with the insurer

within six (6) calendar months of the Cayman Purchaser’s first notification to

the insurer in relation to the relevant claim, the Purchasers may (subject to the remaining

provisions of this Schedule 6) bring a Fundamental Warranty Claim or a Tax Claim (as

applicable) against the Sellers in respect of such matter.

137

2.10 If any Seller pays an amount in discharge

of a Fundamental Warranty Claim or a Tax Claim prior to such claim under the W&I Insurance

Policy having been settled or finally determined, the Cayman Purchaser (on its own behalf

and/or for the benefit of the Brazil Purchaser) shall continue to use best endeavours to

pursue such claim under the W&I Insurance Policy until it is settled or finally determined.

If and to the extent that the Purchasers recover (in whole or in part) any sum from the insurer

in respect of such Fundamental Warranty Claim or Tax Claim (as applicable), the Purchasers

shall promptly (and in any event within five (5) Business Days of recovery) pay (by

wire transfer of immediately available funds) to the relevant Seller(s) an amount equal

to the lower of (i) the amount actually paid by such Seller in discharge of the Fundamental

Warranty Claim or the Tax Claim (as applicable), and (ii) the sum actually recovered

from the insurer in the applicable Relevant Proportion(s) (net of Taxes and less the

reasonable costs of recovery actually incurred by the Purchasers in pursuing such claim under

the W&I Insurance Policy).

2.11 If, the Cayman Purchaser (on its own

behalf and/or for the benefit of the Brazil Purchaser) would have been entitled to recover

amounts in relation to a Fundamental Warranty Claim or Tax Claim under the W&I Insurance

Policy, but the W&I Insurance Policy is terminated as a result of the Cayman Purchaser’s

(on its own behalf and/or for the benefit of the Brazil Purchaser) failure to comply with

the terms of the W&I Insurance Policy (a “Vitiating Policy Breach”),

the liability of the Sellers for such Fundamental Warranty Claim or Tax Claim shall be reduced

by the amount that would have been available under the W&I Insurance Policy but-for such

Vitiating Policy Breach.

3. Time Limits for Bringing Claims

3.1 No Claim shall be brought against any

Seller unless the Purchasers have given the relevant Seller written notice of such Claim

specifying (in reasonable detail) the matter which gives rise to the Claim and the nature

of the Claim, in any event:

(A) in the case of any Claim relating to breach

of Fundamental Warranty (other than a Business Warranty or a Tax Warranty), on or before

the fifth (5th) anniversary of the Completion Date;

(B) in the case of any Tax Claim, on or before

the sixth (6th) anniversary of the Completion Date; and

relating to a breach of a Business Warranty, other than a Fundamental Warranty or a Tax Claim),

on or before the second (2nd) anniversary of the Completion Date.

3.2 Except in the case of a Tax Covenant Claim,

any Claim notified to a Seller in accordance with paragraph 3.1 shall be deemed to

have been irrevocably withdrawn (if such Claim has not been previously satisfied, settled

or expressly withdrawn) if legal proceedings in respect of such Claim have not been commenced

within six (6) months of service of such notice to such Seller, and for this purpose

proceedings shall not be deemed to have been commenced unless they shall have been properly

issued and validly served upon the relevant Seller, provided that in the case of such a Claim

based on a Liability which is contingent or otherwise not capable of being quantified, the

six (6) month period shall commence on the date the relevant Liability becomes an actual

Liability or is capable of being quantified. In the case of a Claim to which paragraphs

2.8 to 2.10 (inclusive) of this Schedule 6 apply, the relevant six-month

period for the purposes of this paragraph 3.2 shall commence when the Purchasers

become entitled to bring the Claim against the Sellers under those provisions.

138

3.3 In the case of a Tax Covenant Claim, any

Claim notified to a Seller in accordance with paragraph 3.1 shall be deemed to have

been irrevocably withdrawn if legal proceedings in respect of such Claim have not been commenced

within six (6) months of the amount of Tax in respect of which the Claim is made being

finally and conclusively determined.

Cure period

3.4 Notwithstanding the foregoing, the relevant

Seller shall have a period of thirty (30) days from receipt of such written notice (or, in

the case of a Claim based upon a Liability which is contingent or otherwise not capable of

being quantified, the date on which the contingent Liability becomes an actual Liability

or the Liability becomes capable of being quantified) to remedy the matter the subject of

the Claim and no legal proceedings shall be commenced in respect of such Claim by the Purchasers

unless such period of thirty (30) days has expired without such matter being so remedied.

No Liability for Contingent or Non-Quantifiable

Claims

3.5 If any breach of the Warranties arises

by reason of some Liability of any member of the Purchasers’ Group which, at the time

the relevant Warranty Claim is notified to the relevant Seller, is contingent only or otherwise

not capable of being quantified, then the relevant Seller shall not be under any obligation

to make any payment in respect of such Claim unless and until such Liability ceases to be

contingent or becomes capable of being quantified. So long as such Claim shall have been

notified to the relevant Seller in accordance with paragraphs 3.1 and 4.1(A) of

this Schedule 6, then the proviso set out at the end of paragraph 3.2 of this

Schedule 6 shall operate to govern the time limit within which legal proceedings must

be commenced in respect thereof and the Purchasers shall not be prevented from making such

a Claim in respect of a contingent or non-quantifiable loss where the Liability does not

become an actual Liability or capable of being quantified until after the expiry of the relevant

time limit set out in paragraph 3.

4. Conduct of Litigation

4.1 Upon the Purchasers or any member of the

Purchasers’ Group becoming aware of any Action or demand against it by any third party

or any other matter likely to give rise to any Claim (including, for the avoidance of doubt,

any claims, actions or demands relating to the BWT for which the Purchasers are or may be

entitled to seek indemnity from Ultratug pursuant to Clause 12.8), other than

a Tax Claim, which shall be governed by Schedule 9 (Tax Covenant), the Purchasers

shall and shall procure the relevant member of the Purchasers’ Group shall:

(A) promptly, and in any event within thirty

(30) days thereof, notify the relevant Seller by written notice in accordance with paragraph

3.5 of this Schedule 6;

139

(B) subject to the relevant Seller indemnifying

on an after-Tax basis the Purchasers and each relevant member of the Purchasers’ Group

(in a form reasonably satisfactory to the Purchasers) against any Liability, cost, damage

or expense which may be incurred thereby (but without implying any admission of Liability

thereby), take such action and give such information and access to its personnel, premises,

chattels, documents and records (including in electronic form) (which the Purchasers shall

procure are preserved) to the relevant Seller and its professional advisers as the relevant

Seller may reasonably request and the relevant Seller shall be entitled to require any relevant

member of the Purchasers’ Group to take such action and give such information and assistance

reasonably required in order to avoid, dispute, resist, mitigate, settle, compromise, defend

or appeal any claim in respect thereof or adjudication with respect thereto;

settlement or compromise with any third party in relation to any such claim or adjudication

without the prior written consent of the relevant Seller, such consent not to be unreasonably

withheld or delayed; and

(D) take or procure that there is taken all

reasonable action requested, in writing, by the relevant Seller or otherwise to mitigate

any loss suffered by it or any member of the Purchasers’ Group in respect of which

a Claim (other than a Tax Claim) could be made.

5. No Liability if Loss is Otherwise Compensated

for

5.1 No Liability shall attach to any Seller

for any Claim to the extent that damages or any other amount has already been recovered by

any member of the Purchasers’ Group in respect of the same matter, loss or Liability

under any other terms of any other Transaction Document or any other document entered into

pursuant hereto or other reimbursement or restitution by the Sellers and accordingly the

Purchasers’ Group may only recover once in respect of the same matter, loss or Liability.

5.2 The Sellers shall not be liable to the

extent that the subject of the Claim has been or is made good or is otherwise fully compensated

for without cost to the Purchasers or any other member of the Purchasers’ Group.

6. Recovery from Insurers and Other Third

Parties

6.1 If, in respect of any matter which would

give rise to a Claim (other than a Tax Claim), any member of the Purchasers’ Group

is entitled to claim under any policy of insurance, then the appropriate member of the Purchasers’

Group shall make a claim against the relevant insurers and use all reasonable endeavours

to pursue such claim in an expedient manner and in accordance with the terms of the applicable

policy, and, in the event that the Purchasers or any other member of the Purchasers’

Group recovers any insurance proceeds, the amount of the Claim against the relevant Seller

shall be reduced by the amount recovered less the reasonable costs of such pursuit and any

Tax thereon.

6.2 Where the Purchasers or any other member

of the Purchasers’ Group is at any time entitled to recover from some other person

(including any sub-contractor or consultant or any Tax Authority but other than any insurer),

any sum in respect of any matter giving rise to a Claim (other than a Tax Claim), the Purchasers

shall, and shall ensure that the relevant member of the Purchasers’ Group concerned

shall, take reasonable steps to enforce such recovery and, in the event that the Purchasers

or any other member of the Purchasers’ Group recovers any amount from such other person

in respect of such matter, the amount of the Claim against the relevant Seller shall be reduced

by the amount recovered less the reasonable costs and any Tax incurred by the Purchasers’

Group in making such recovery.

140

6.3 If any Seller pays at any time to the

Purchasers or any other member of the Purchasers’ Group an amount pursuant to a Claim

(other than a Tax Claim) and the Purchasers or member of the Purchasers’ Group subsequently

recovers from some other person any sum in respect of any matter giving rise to such Claim,

the Purchasers shall, and shall ensure that the relevant member of the Purchasers’

Group shall, promptly repay to the relevant Seller in immediately available funds the lesser

of: (i) the amount paid by the relevant Seller to the Purchasers or other member of

the Purchasers’ Group; and (ii) the sum (including interest (if any)) recovered

from such other person (less the reasonable cost of recovery and any Tax thereon).

7. Voluntary Acts

7.1 No Claim shall lie against any Seller

to the extent that such Claim (other than a Tax Claim) is attributable to:

(A) any voluntary act, omission, transaction

or arrangement carried out at the written request of or with the written consent of the Purchasers

or any member of the Purchasers’ Group before Completion or pursuant to the terms of

this Agreement or any of the other Transaction Documents;

(B) any voluntary act, omission, transaction

or arrangement carried out by the Purchasers or on their behalf or by persons deriving title

from the Purchasers or by another member of the Purchasers’ Group on or after Completion

otherwise than in the ordinary course of business of the Target Group as carried on at Completion

to fulfil a legally binding commitment of any member of the Target Group entered into prior

to Completion, or undertaken in order to comply with applicable Law; or

of the provisions of paragraph (C) of this Schedule 6 after the date hereof

by the Purchasers or on their behalf or by persons deriving from the Purchasers or by another

member of the Purchasers’ Group on or after Completion.

7.2 No Seller shall be liable for any Claim

(other than a Tax Claim) which would not have arisen but for, or to the extent that such

Claim is increased by, any reorganisation or change in ownership of any member of the Purchasers’

Group after Completion or change in any accounting basis on which any member of the Purchasers’

Group values its assets or any accounting basis, method, policy or practice of any member

of the Purchasers’ Group in each case as compared to those in force or having effect

at the date of this Agreement.

sheet and/or profits and loss statements of the Accounts or has otherwise been reflected or identified in the Accounts (including in

the notes thereto).

No matter shall be the subject of a

Claim (other than a Tax Claim) to the extent that it is taken into account in the Completion Statement.

10. Future Legislation

of any Claim (other than a Tax Claim) to the extent that the Liability occurs or is increased (in which case, no Liability shall arise

in respect of such increase only) directly or indirectly as a result of:

(A) the passing of, or a change in, any Law

or administrative action, not in force on or prior to the date of this Agreement;

(B) any change after the date of this Agreement

of any generally accepted interpretation or application of any of the foregoing or in the

enforcement policy or practice of the relevant authorities; or

or the withdrawal of any extra-statutory concession or other formal agreement or arrangement

currently granted by or made with any Governmental Authority (whether or not having the force

of Law).

11. Purchasers’ Knowledge

11.1 Without prejudice to paragraph 12

of this Schedule 6, the Sellers shall not be liable in respect of any Claim under

the Warranties to the extent that the Purchasers were aware of the Claim or the matter forming

the basis of the Claim before the date of this Agreement.

12. Disclosure

to claim that any fact, matter or circumstance causes any of the Warranties (other than the

Fundamental Warranties) to be breached if Disclosed in the Data Room or in, or by virtue

of, the Disclosure Letter (including in any document referred to in, or delivered as part

of, the Disclosure Letter) or by any other Transaction Document.

matter or circumstance which has first arisen since the date of this Agreement and which

could reasonably be expected to constitute a breach of any Fundamental Warranty, and (ii) acknowledge

set forth in paragraph 6 of Schedule 1 (Conditions), or (ii) otherwise

proceed to Completion,

brought).

2. Review of Draft Completion Statement

2.1 After receipt of the Draft Completion

Statement, the Sellers shall have thirty (30) calendar days (the “Review Period”)

to review the Draft Completion Statement.

2.2 During the Review Period, the Purchasers

shall and shall procure that each member of the Target Group shall provide the Sellers with

reasonable access during normal business hours to any relevant personnel, Representatives,

premises, Books and Records, calculations and working papers of the Target Group as any Seller

or its respective Representatives may reasonably request in connection with its review of

the Draft Completion Statement, provided that such access shall be in a manner that does

not interfere with the ordinary course of business operations of the Purchasers’ Group

or the Target Group. Any such personnel and Representatives of the Purchasers’ Group

and the Target Group shall be instructed to reasonably co-operate and give prompt information

and explanations to the Sellers and their respective personnel, Representatives and advisors

for such purpose.

3. Dispute Mechanism

3.1 On or prior to the last day of the Review

Period, the Sellers may jointly object to the Draft Completion Statement by delivering to

the Purchasers a written statement setting forth the Sellers’ objections in reasonable

detail, indicating each disputed item, amount and the basis for the Sellers’ disagreement

therewith (the “Statement of Objections”).

3.2 If the Sellers do not deliver the Statement

of Objections before the expiration of the Review Period, the Draft Completion Statement

shall be final and binding and shall be the Completion Statement for the purposes of this

Agreement and the Adjustment Amount reflected therein shall be deemed to be accepted by the

Sellers as the final Adjustment Amount for the purposes of this Agreement.

3.3 If the Sellers deliver the Statement of

Objections before the expiration of the Review Period, the Purchasers and the Sellers will

negotiate in good faith to resolve such objections within thirty (30) calendar days after

delivery of the Statement of Objections (the “Resolution Period”). If

the disputed matters set forth in the Statement of Objections are so resolved within the

Resolution Period, the Draft Completion Statement (with such changes as may have been agreed

in writing by the Purchasers and the Sellers) shall be final and binding and shall be the

Completion Statement and the Adjustment Amount reflected in therein shall be the final Adjustment

Amount for the purposes of this Agreement.

3.4 If the Purchasers and the Sellers fail

to reach an agreement with respect to the matters set forth in the Statement of Objections

before the expiration of the Resolution Period, then the matters remaining in dispute (“Disputed

Matters” and any matters agreed in writing to not be so disputed, the “Undisputed

Matters”) shall be submitted for resolution to:

(A) an independent firm of chartered accountants

of international repute, mutually selected in writing by the Purchasers and the Sellers;

(B) failing such mutual selection within ten

(10) Business Days following expiry of the Resolution Period, the person nominated by

the President of the Institute of Chartered Accountants in England and Wales upon the joint

application thereto by the Purchasers and the Sellers (such person being an individual at

an independent firm of chartered accountants),

146

(the “Agreed Accountant”),

on the basis that the Agreed Accountant is to make a decision in relation to the Disputed Matters and notify the Purchasers and the Seller

of its decision within thirty (30) Business Days of receiving the reference or such longer reasonable period as the Agreed Accountant

may determine.

3.5 The Agreed Accountant, acting as an expert

and not an arbitrator, shall resolve the Disputed Matters only and make any adjustment to

the Adjustment Amount and the Draft Completion Statement. The Parties agree that all adjustments

shall be made without regard to materiality. The Agreed Accountant shall only decide the

specific Disputed Matters and its decision for each Disputed Amount Matter must be within

the range of values assigned to each such item in the Draft Completion Statement and the

Statement of Objections, respectively, and be made in accordance with the terms and definitions

of this Agreement, including where relevant the accounting policies, principles, practices,

bases and methodologies set out in Part C of this Schedule 8.

3.6 The costs of the Agreed Accountant shall

be paid based on the inverse proportion of the relative success of the Purchasers and the

Sellers with respect to the Disputed Matters. By way of illustrative example, if the Sellers

dispute an item of $100 and assert that it should be $200 and the Agreed Accountant determines

that it is $160, the Purchasers shall pay 60% (and the Sellers shall pay 40%) of the fees

of the Agreed Accountant.

3.7 Each of the Sellers and the Purchasers

shall respectively provide or procure the provision to the Agreed Accountant of all such

information and assistance as the Agreed Accountant shall reasonably require, including:

(A) by their respective personnel, Representatives

and advisers;

(B) in the case of each Seller, the Books

and Records and personnel of its Relevant Seller Group; and

and Records and personnel of the Target Group,

in each case during normal office hours

and subject to reasonable notice.

3.8 The decision of the Agreed Accountant

shall, in the absence of fraud or manifest error, be final and binding on the Purchasers

and the Sellers and the Draft Completion Statement amended as necessary to reflect the decision

of the Agreed Accountant in relation to the Disputed Matters; and any agreement between the

Purchasers and the Sellers in respect of the Undisputed Matters, shall be the final Completion

Statement, containing the Adjustment Amount, for the purposes of this Agreement. In the event

of the Agreed Accountant’s manifest error, the Agreed Accountant shall be required

to rectify such error and the corrected determination of the Completion Statement shall be

final and binding on the Sellers and the Purchasers, save for fraud.

147

3.9 Subject to paragraph 3.10,

if the Adjustment Amount is:

(A) a negative number, then:

(i) Wilson Sons shall on the Post-Completion

Adjustment Payment Date pay, in accordance with Clause 12, to the Purchasers’

Bank Account an amount equal to its Relevant Proportion of the Adjustment Amount (expressed

as a positive number);

(ii) Ultranav shall pay on the Post-Completion

Adjustment Payment Date, in accordance with Clause 12, to the Purchasers’

Bank Account an amount equal to its Relevant Proportion of the Adjustment Amount (expressed

as a positive number); and

(iii) either:

(a) in the event that the Ultratug’s

Relevant Proportion of the Adjustment Amount (expressed as a positive number) is less than

or equal to the Retention Amount (as at the Post-Completion Adjustment Payment Date), the

Purchasers shall pay on the Post-Completion Adjustment Payment Date, in accordance with Clause 12,

to Ultratug’s Seller Bank Account an amount equal to:

(1) the relevant Ultratug Post-Completion

Gross Adjustment Payment;

(2) minus the Post-Completion Adjustment

BWT Amount; or

(b) in the event that Ultratug’s Relevant

Proportion of the Adjustment Amount (expressed as a positive number) exceeds the Retention

Amount (as at the Post-Completion Adjustment Payment Date), the Purchasers shall be entitled

to retain the entirety of the Retention Amount and Ultratug shall pay on the Post-Completion

Adjustment Payment Date, in accordance with Clause 12, to the Purchasers’

Bank Account an amount equal to:

(1) Ultratug’s Relevant Proportion

164

(v) which is the setting off or utilisation

of a Purchasers’ Relief or Purchasers’ Repayment in circumstances giving rise

to a Deemed Tax Liability; or

(F) such Tax Liability would not have arisen

or would have been reduced but for a failure or omission on the part of the relevant Purchaser(s) and/or

a member of the Target Group after Completion to make or submit all claims, disclaimers,

elections, consents or other similar documents which have been assumed to have been made

or submitted for the purposes of computing the provision or reserve for Tax in the Accounts,

to comply with Law or a generally accepted accounting practice as, and to the extent that,

it applied to the relevant company at the date of this Agreement;

(H) such Tax Liability has been made good

without cost to a member of the Target Group or to any other member of the Purchasers’

Group;

that Tax Liability is attributable were actually earned or received by or accrued to (but

received) by a member of the Target Group on or before Completion and were not reflected

in the Completion Statement but should have been so reflected;

(K) the relevant Purchaser(s) have otherwise

made recovery in respect of that Tax Liability under this Schedule 9 or by means of

a Claim for breach of any of the Warranties or under any other provision of any of the Transaction

Documents; or

(L) such Tax Liability comprises a penalty,

charge or interest and is solely attributable to any unreasonable delay or failure on the

part of any member of the Purchasers’ Group.

3.2 Certain provisions of Schedule 6

(Limitations on Liability) contain further limitations which apply to this Schedule 9

(including setting certain financial and time limits).

Relief, as are available to a member of the Target Group to reduce, eliminate or make good

any Tax Liability in respect of which the relevant Purchaser(s) would have been able

to make a Claim against the relevant Seller under this Schedule 9, the said use being

to effect the reduction, elimination or making good of any such Tax Liability to the extent

specified by the relevant Seller and permitted by Law; and

(B) as the Sellers may require to make all

such claims and elections specified in respect of any Tax Period of a member of the Target

Group commencing before Completion or in respect of any Event occurring (or deemed to occur)

on or before Completion as have the effect of reducing, eliminating or making good any such

Tax Liability as is mentioned in paragraph 4.1(A), provided that no such claim or

paragraph 9.

4.2 The Purchasers shall not be obliged under

this paragraph 4 to take, or to procure that any member of the Target Group takes,

any action which:

(A) would have the effect of giving rise to

any Tax Liability of any member of the Target Group for which no Claim could be made under

this Schedule 9; or

(B) would have the effect of preventing from

arising (or reducing) a Relief which would, but for that action, have been a Purchasers’

Relief.

5. Overprovisions

5.1 Subject to the provisions of paragraph

8 (Overprovisions, Reliefs and Repayments: General), if any provision for Tax in the

Accounts is an overprovision otherwise than as the result of any matter referred to in paragraph

1.8, then the amount of such overprovision shall be dealt with in accordance with paragraph

5.2.

5.2 Where it is provided under paragraph

5.1 that any amount shall be dealt with in accordance with paragraph 5.2, it shall

be divided between the Sellers in their Relevant Proportions (each such proportional amount,

a “Seller’s Overprovision Amount”) and each Seller’s Overprovision

Amount shall be:

(A) first set off against any payment then

due from the relevant Seller under this Schedule 9;

(B) to the extent there is an excess, a refund

shall be made to the relevant Sellers of any previous payment or payments made by that Seller

under this Schedule 9 and not previously refunded under paragraphs 5.2(B),

8, this paragraph 6.1 shall apply if a member of the Target Group has received

or obtained or is entitled to receive or obtain a Relief, other than a Purchasers’

Relief or a Relief arising as a result of any matter referred to in paragraph 1.8.

6.2 Where paragraph 6.1 applies, to

the extent that:

(A) the Relief arises as a consequence of

on or before Completion for the purposes of any Tax but excluding such Relief to the extent

that it is taken into account in the calculation of any Income, Profits or Gains;

(B) the Relief is taken into account in the

from any Seller under this Schedule 9,

and in each case, excluding

any Relief that is an Accounts Relief, then as and when:

(i) the liability of any member of the Purchasers’

Group to make an actual payment of or in respect of Tax (not being a Tax Liability in respect

of which any Seller would be liable under this Schedule 9, ignoring any financial

or time limits) is reduced by reason of that Relief, the amount by which that liability is

so reduced shall be dealt with in accordance with paragraph 6.3; or

(ii) any member of the Purchasers’ Group

receives a repayment of or in respect of Tax by reason of that Relief, the amount of such

repayment less any Tax thereon and any costs of recovery incurred by that or any other member

of the Purchasers’ Group shall be dealt with in accordance with paragraph 6.3

(except to the extent that such amount falls to be dealt with under paragraph 6.3

as a result of paragraph 6.2).

6.3 Where it is provided under paragraph

6.2 that any amount shall be dealt with in accordance with paragraph 6.3, it shall

be divided between the Sellers in their Relevant Proportions (each such proportional amount,

a “Seller’s Relief Amount”), and each Seller’s Relief Amount

(A) first set off against any payment then

due from the relevant Seller under this Schedule 9;

167

shall be made to the relevant Seller of any previous payment or payments made by the relevant

Seller under this deed and not previously refunded under paragraphs 5.2(B), 6.3(B) or

to in paragraph 6.3(B) is not exhausted under that paragraph, then the remainder

which become due from the relevant Seller under this Schedule 9.

7. Repayments

7.1 Subject to the provisions of paragraph

8 (Overprovisions, Reliefs and Repayments: General) this paragraph 7.1 shall apply

to the extent that:

(A) the repayment is of Tax paid as a consequence

on or before Completion for the purposes of any Tax but excluding such repayment to the extent

that it is a repayment of Tax paid in respect of or by reference to any Income, Profits or

Gains; or

(B) the repayment is of Tax paid in respect

of any Income, Profits or Gains which were or were thought to be earned, accrued or received

(i) on or before Completion, or (ii) in respect of a period ending on or before

8. Overprovisions, Reliefs and Repayments:

General

8.1 Upon any Purchaser or member of the Target

Group becoming aware of the existence of a Seller’s Overprovision Amount, a Seller’s

Relief Amount or a Seller’s Repayment Amount, the relevant Purchaser(s) shall

give written notice to the relevant Seller(s) setting out reasonably sufficient details

of such Seller’s Overprovision Amount, Seller’s Relief Amount or Seller’s

Repayment Amount.

8.2 The provisions of paragraphs 5, 6 or

7 do not apply in respect of a particular Seller’s Overprovision Amount, Seller’s

Relief Amount or Seller’s Repayment Amount unless any member of the Purchasers’

Group becomes aware of the existence thereof, within the period ending on or before the sixth

anniversary of Completion.

8.3 Where there would otherwise be any two

or more of a Seller’s Overprovision Amount, a Seller’s Relief Amount and a Seller’s

Repayment Amount in respect of the same matter, the relevant Seller(s) shall be entitled

to the benefit of only one such amount to the exclusion of the others.

9. Recovery From Other Persons

9.1 If, in the event of any payment becoming

due from any Seller under paragraph 2 or in respect of a Claim for breach of a Tax

Warranty, a member of the Target Group either is immediately entitled at the due date for

the making of that payment to recover from any person (excluding any other member of the

Purchasers’ Group) any sum (including any interest) in respect of the matter that has

resulted in that payment becoming due from any Seller, or within six (6) years from

Completion becomes entitled to make such a recovery, then the relevant Purchaser(s) shall

procure that the member of the Target Group entitled to make that recovery shall promptly

notify the relevant Seller(s) of its entitlement and shall, if so required by the relevant

Seller(s) and, subject to the relevant Purchaser(s) and the relevant member of

the Target Group first being indemnified on an after-Tax basis (in a form reasonably satisfactory

to the relevant Purchaser(s)) by the relevant Seller(s) against any Tax that may be

suffered on receipt of that amount and any reasonable out of pocket costs and expenses that

may be incurred in recovering that amount, take all reasonable steps to enforce that recovery

(keeping the relevant Seller(s) reasonably informed of the progress of any action taken

and providing the relevant Seller(s) with copies of all material correspondence and

documentation) and to the extent that:

(A) the relevant Seller(s) have not yet

made a payment in respect of the matter in question, the amount due from the relevant Seller(s) in

respect of that matter shall be reduced (but not below nil) by an amount (allocated between

the relevant Sellers in proportion to their Relevant Proportions where there is more than

one relevant Seller) equal to the sum so recovered by the member of the Target Group in respect

of that matter less any Tax thereon and any reasonable costs of recovery incurred by that

or any other member of the Target Group or the Purchasers’ Group (save to the extent

that the amount has already been made good by any Seller(s)); and

(B) the relevant Seller(s) have made

a payment in respect of the matter in question, the relevant Purchaser(s) shall account

to the relevant Seller(s) for whichever is the lesser of (allocated between the relevant

Sellers in proportion to their Relevant Proportions where there is more than one relevant

Seller):

(i) any sum so recovered by the member of

the Target Group in respect of that matter less any Tax thereon and any costs of recovery

incurred by that or any other member of the Target Group or the Purchasers’ Group (save

to the extent that the amount has already been made good by any Seller(s)); and

169

(ii) the amount paid by the relevant Seller(s) in

respect of that matter.

9.2 If, in addition to the provisions of this

Schedule 9, the provisions of any of paragraphs 5, 6 or 7 would apply

in respect of a repayment of Tax, the provisions of paragraphs 5, 6 or 7 (as

applicable) and not the provisions of this Schedule 9 shall apply in relation to that

repayment of Tax.

10. Tax Authority Claims Procedure

10.1 If the relevant Purchaser(s) or

a member of the Target Group becomes aware of any Tax Authority Claim which may reasonably

result in the relevant Purchaser(s) making a Claim against a Seller either under this

Schedule 9 or for breach of any of the Tax Warranties, the relevant Purchaser(s) shall:

(A) give, or shall procure that the relevant

member of the Target Group gives, written notice of that Tax Authority Claim to the relevant

Seller(s) as soon as reasonably practicable and, wherever possible, at least 15 days

prior to the last date on which such Tax Authority Claim can be appealed (such written notice

to include details of such Tax Authority Claim, the due date for payment and the time limits

for appeal, and so far as practicable, the amount of Tax involved), and where the relevant

Purchaser(s) fail to comply with this obligation, the liability of the relevant Seller(s) under

this Schedule 9 in respect of such Tax Authority Claim shall be nil, except to the

extent that absent the relevant Purchaser(s)’ breach of this paragraph 10.1(A) the

relevant Seller(s) would have been liable under this Schedule 9; and

(B) procure that the relevant member of the

Target Group takes such action and gives such information and assistance in connection with

the affairs of the member of the Target Group as the relevant Seller(s), acting jointly (if

there is more than one relevant Seller), may reasonably and promptly by written notice request,

to avoid, dispute, resist, appeal, compromise or defend the Tax Authority Claim, provided

that the relevant Seller(s) shall severally and proportionally (in their respective

Relevant Proportions) indemnify on an after-Tax basis (in a form reasonably satisfactory

to the relevant Purchaser(s)) the relevant Purchaser(s) and the relevant member of the

Target Group against all losses, costs, damages and expenses (including any additional liability

to Tax) which the relevant Purchaser(s) or relevant member of the Target Group may suffer

or incur as a result of taking such action (and which would not have arisen or been incurred

but for the relevant Seller(s) having exercised any rights under this paragraph 10.1).

10.2 The actions which the relevant Seller(s) may

reasonably request under paragraph 10.1(B) include the relevant member of the

Target Group applying to postpone (so far as legally possible) the payment of any Tax and/or

allowing the relevant Seller(s) to take on or take over at their own expense the conduct

of all or any proceedings of whatsoever nature arising in connection with the Tax Authority

Claim in question, provided that the Tax Authority Claim relates wholly and exclusively to

a Tax Liability for which the Seller(s) are liable under a Tax Claim. If the relevant

Seller(s) take on or take over the conduct of proceedings, the relevant Purchaser(s) shall

provide and shall procure that the relevant member of the Target Group provides such information

and assistance as the relevant Seller(s) may reasonably require in connection with the

preparation for and conduct of those proceedings.

170

10.3 Paragraph 10.1(B) shall not

apply in respect of any Tax Authority Claim:

(A) to the extent that it would involve contesting

any Disputed Claim before any court or other appellate body (excluding the Tax Authority

or body which has made the Disputed Claim) unless tax counsel (of at least 10 years call)

opines in writing, following disclosure of all relevant facts and circumstances, that an

appeal against the Tax Authority Claim in question is more likely than not to succeed. The

relevant Purchaser(s) and the relevant Seller(s) shall use reasonable endeavours

to agree the appointment of such tax counsel. In the event that such appointment cannot be

agreed, the relevant Seller(s) shall be entitled to appoint tax counsel at their sole

discretion;

(B) where it derives from or arises out of

any dishonest or fraudulent act or omission by a Seller or a relevant member of the Target

Group prior to Completion;

the relevant Seller(s)’ receipt of written notice of the Tax Authority Claim from the

relevant Purchaser(s), the relevant Seller(s):

(i) do not request that the relevant Purchaser(s) or

the relevant member of the Target Group take any action under paragraph 10.1(B); or

(ii) the relevant Seller(s) fail to offer

to indemnify the relevant Purchaser(s) and/or the relevant member of the Target Group

(as appropriate),

in which case the relevant Purchaser(s) and

the relevant member of the Target Group shall (without prejudice to the Purchasers’ rights under this Schedule 9) be free

to contest, pay or settle the Tax Authority Claim on such terms as it may, in its absolute discretion, consider fit;

(D) if the relevant Sellers:

(i) are declared insolvent or bankrupt or

legal proceedings are started for the appointment of a receiver, administrator, trustee in

bankruptcy, insolvency practitioner or similar officer of the relevant Seller(s); or

(ii) are unable to pay their debts as they

fall due within the meaning of any relevant insolvency or company legislation.

10.4 Neither the Purchasers nor the relevant

member of the Target Group shall be required to take any action under paragraph 10.1(B) if

it reasonably considers that taking such action would be reasonably likely to cause a material

prejudice to the Tax affairs or bona fide commercial interests of the member of the Target

Group which is the subject of the Tax Authority Claim or the Target Group as a whole or the

Purchasers’ Group as a whole.

171

10.5 Nothing in paragraph 10.1(B) shall

(i) require the Purchasers to procure, or (ii) permit the relevant Seller(s), in

having conduct of any proceedings, to allow, direct or require, that a member of the Target

Group:

(A) submit any material statement, defence,

claim, notice, election, filing or other document or material correspondence proposed to

be submitted to any Tax Authority, court or tribunal by or at the request or direction of

the relevant Seller(s) (a “Sellers’ Dispute Document”), unless

the same has been submitted in draft form to the relevant Purchaser(s) before the lapse

of one half of the period beginning on the later of (i) the date the relevant Purchaser(s) or

a member of the Target Group provided written notice of the relevant Tax Authority Claim

to the relevant Seller(s) and (ii) the date the relevant Purchaser(s) or a

member of the Target Group provided written notice to the relevant Seller(s) (pursuant

to the Purchasers’ obligations under this paragraph 10) of the latest document

or correspondence received from or sent to the relevant Tax Authority and ending on the date

on which such Sellers’ Dispute Document shall be required to be sent to the Tax Authority,

court or tribunal (each such period, a “Sellers’ Dispute Review Period”),

and the relevant Seller(s) have taken into account all reasonable comments of the relevant

Purchaser(s) on such Sellers’ Dispute Document that are received two (2) days

before the lapse of such Sellers’ Dispute Review Period; or

(B) compromise or settle any Disputed Claim,

unless the prior written agreement of the relevant Purchaser(s) is sought (such agreement

not to be unreasonably withheld, conditioned or delayed);

10.6 Where the relevant Seller(s) do

not take on or take over the conduct of proceedings or exercise their rights under paragraph

10.1(B) in connection with the Tax Authority Claim, the relevant Purchaser(s) shall,

or shall procure that the relevant member of the Target Group shall, keep the relevant Seller(s) informed

of all material matters pertaining to such Tax Authority Claim, including providing the relevant

Seller(s) with copies of all material relevant information, correspondence or other

written records with any Tax Authority to the extent that it relates to such Tax Authority

Claim, and the opportunity to comment on any material documentation relating to such Tax

Authority Claim, such comment to be submitted to the relevant Purchaser(s) at least

five (5) Business Days prior to its submission to the relevant Tax Authority, which

the relevant Purchaser(s) shall consider in good faith.

10.7 Where a Claim for breach of Tax Warranty,

or a Claim pursuant to the Tax Covenant is made exclusively against the W&I Insurance

Policy, any conduct of claims provision in that W&I Insurance Policy, and not the provisions

of this Schedule 9, shall apply.

10.8 Where a Claim for breach of Tax Warranty,

or a Claim pursuant to the Tax Covenant is made first against the W&I Insurance Policy

but where the Sellers may reasonably be or become liable for such Claim or any part of such

Claim (including, for the avoidance of doubt, any amount described in Clause 32.5)

under this Schedule 9, conduct of the Claim shall be governed by the provisions of

this Schedule 9 to the extent they are consistent with the obligations of the relevant

Purchaser(s) and any relevant member of the Target Group under the W&I Insurance

Policy.

172

11. Tax Returns

11, the “relevant Seller(s)” shall mean:

Completion, the relevant Purchaser shall procure that such member of the Target Group shall

cause such documentation or correspondence to be signed and submitted to the appropriate

Tax Authority on a timely basis without amendment or with such amendments as the relevant

Seller(s) shall agree (acting jointly), provided that the relevant Purchaser shall not

be obliged to procure such action in respect of any documentation or correspondence that

contains information that to the best of that member of the Target Group’s knowledge

is incorrect, incomplete or misleading.

11.3 The relevant Sellers shall provide the

relevant Purchaser(s) with a copy of each such Tax Return where such return relates

solely to Corporate Income Tax (Imposto de Renda da Pessoa Jurídica –

IRPJ) and/or Social Contribution on Net Income (CSLL) Tax payables (Contribuição

Social sobre o Lucro Líquido), in draft form for its review and comment no less

than ten (10) days before the last date on which the return may be filed with the appropriate

Tax Authority without incurring interest and penalties (“Filing Date”),

and shall consider in good faith the comments from the relevant Purchaser(s).

relevant Seller(s)’ comments, to the extent such comments relate to a matter: (i) for

which the relevant Seller(s) may be liable under this Agreement; or (ii) which

could affect a Covenantor Liability, and provided that reflection of the Seller(s)’

comments would not result in the contravention of applicable Law; and

173

the appropriate Tax Authority on a timely basis and without amendment (save with the written

consent of the relevant Seller(s) which shall not be unreasonably withheld, conditioned

or delayed);

11.5 Except as set out in paragraph 11.2

above, the Purchasers shall prepare all documentation and deal with all matters (including

correspondence) relating to any Pre-Completion Tax Return or Straddle Tax Return, provided

that, where there is or is to be any correspondence, meeting or telephone call with any Tax

Authority in relation to such Tax Returns that relate to a matter: (i) for which the

relevant Seller(s) may be liable under this Agreement; or (ii) which could affect

a Covenantor Liability:

(A) the Purchasers shall promptly send copies

of all such correspondence received and copies of all draft replies to the relevant Seller(s),

give the relevant Seller(s) an opportunity to make comments jointly thereon a reasonable

time in advance of the submission of those replies to the relevant Tax Authority and properly

(B) the Purchasers shall give reasonable advance

notice of any such meeting or call to the relevant Seller(s), and the relevant Seller(s) shall

each be entitled to nominate an individual to attend and not participate in such meeting

or call.

of this paragraph 11, the parties acknowledge and agree that, in preparing any Tax

Return in accordance with paragraphs 11.2 or 11.4, and preparing any documentation

and dealing with any matter in relation to any Tax Return in accordance with paragraphs

11.2(C) and 11.5, documentation will be prepared and the returns or matter

will be dealt with (as the case may be) in accordance with the past practice of the member

of the Target Group in question, provided that the Purchasers or any member of the Target

Group shall not be obliged to do anything that is not to the best of the relevant member

of the Target Group’s knowledge correct and complete, or that would be reasonably likely

to cause a material prejudice to the Tax affairs or bona fide commercial interests of the

Purchasers’ Group.

11.7 The Purchasers shall procure that the

Target Group shall afford such access to their personnel, books, accounts and records and

provide such assistance as is necessary and reasonable to enable the relevant Seller(s) to

exercise its rights, and fulfil its obligations, under this paragraph 11.

11.8 The relevant Seller(s) shall procure

save with the written consent of the relevant Seller(s) (which shall not be unreasonably

withheld, conditioned or delayed) or pursuant to a notice issued by a Tax Authority requiring

the same under sufferance of penalty.

174

11.10 Where there is conflict between the

foregoing provisions of this paragraph 11 and the provisions of paragraph

4 or paragraph 10, the provisions of paragraph 4 or paragraph 10

take precedence over the foregoing provisions of this paragraph 11.

this Schedule 9, the payment shall be made in cleared funds.

12.2 Where any action is taken to dispute,

defend, resist, appeal or compromise any Tax Authority Claim (a “Disputed Claim”),

the relevant Seller(s) are to pay any required sum under paragraph 2 by

the date falling five (5) Business Days after the date when the amount of Tax that is

the subject matter of the Disputed Claim is finally and conclusively determined, except to

the extent the claim cannot be disputed, defended, resisted, appealed or compromised (as

the case may be) prior to all or a portion of the Tax which is the subject matter of the

Disputed Claim being paid, in which case, an amount equal to that amount of Tax shall be

paid by the relevant Seller(s) (in their respective Relevant Proportions) promptly upon

receipt by that Seller of a written notice from the relevant Purchaser(s) for that amount. Any

such amount of Tax paid but subsequently recovered by the relevant Purchaser(s) or a

member of the Target Group (together with interest paid by the Tax Authority) upon resolution

of the Disputed Claim shall be repaid to the relevant Seller(s) (in their respective

Relevant Proportions) forthwith, less any Tax thereon and any reasonable costs of recovery

incurred by any member of the Target Group or the Purchasers’ Group, notwithstanding

the other provisions in this Schedule 9.

12.3 In any other case, the due date for the

making of any payment under this Schedule 9 shall be the later of the date falling

under this Schedule 9 has been notified of the obligation to make the payment by the

party entitled to claim the payment, and:

(A) in the case of a payment in respect of

an Actual Tax Liability, the date falling on the later of:

(i) five (5) Business Days before the

last date upon which the Tax concerned can be paid without the person liable to pay it incurring

Relief other than a repayment of Tax, the date falling ten (10) Business Days before

the date in which the relevant member of the Target Group becomes due to pay any Tax which

it would not, but for such Loss, have had to pay;

175

(ii) which relates to the Loss of a right

to a repayment of Tax, the date falling ten (10) Business Days before the day on which

such repayment (or increased repayment) of Tax would have been due and for this purpose it

shall be assumed that the repayment would have become due at the earliest possible date;

(iii) which relates to the setting off or

utilisation of any Purchasers’ Relief or Purchasers’ Repayment, the date falling

five (5) Business Days before the date on which the relevant member of the Target Group

Relief or Purchasers’ Repayment), have been liable to pay any Tax; and

costs and expenses under paragraph 2.1(C), five (5) Business Days before the

13.1 All sums payable by any Seller to any

Purchaser under this Schedule 9 shall be paid free and clear of all deductions or

withholdings whatsoever, save only as may be required by Law and, if any such deduction or

withholding is required, the relevant Seller shall provide such evidence satisfactory to

the relevant Purchaser, acting reasonably, that such deduction or withholding has been made

and appropriate payment made to the relevant Tax Authority.

13.2 If any deductions or withholdings for,

or on account of, Tax are required by Law to be made from any of the sums payable as mentioned

in paragraph 13.1 then, except to the extent that the sum constitutes interest, the

relevant Seller shall be obliged to pay to the relevant Purchaser(s) such additional

amount as will, after such deduction or withholding has been made, leave the relevant Purchaser(s) with

the same amount as they would have been entitled to receive in the absence of any such requirement

for that Seller to make a deduction or withholding.

13.3 If any sum payable by any Seller to any

Purchaser under this Schedule 9 is required by Law to be brought into charge to Tax

in the hands of the Purchaser, then, except to the extent that the sum constitutes interest,

the relevant Seller shall pay such additional amount as shall be required to ensure that

the total amount received by the relevant Purchaser(s) is equal to the amount that would

have been received if the sum payable by that Seller were not required by Law to be brought

into charge to Tax in the hands of the relevant Purchaser(s).

13.4 The relevant Purchaser(s) shall

use reasonable endeavours to obtain and utilise a Relief in respect of any deduction or withholding

in respect of which an additional amount has been paid pursuant to paragraph 13.2

and in respect of any such additional amount and, to the extent that any such Relief is obtained

and utilised by the relevant Purchaser(s), the relevant Purchaser(s) shall pay to the

relevant Seller, within ten Business Days of utilising such Relief, such amount as will leave

the relevant Purchaser(s) in the same after-Tax position as that in which they would

have been if no such deduction or withholding had been required by Law to be made in respect

of the payment from that particular Seller.

relevant Seller shall pay to the relevant Purchaser(s) an amount equal to the Relevant

Proportion of any Tax Liability of a member of the Target Group in respect of Tax which is

chargeable directly or primarily against, or arises directly or primarily in consequence

of or by reference to anything done by, any person that (i) is or may be treated for

the purposes of any Tax as being or having been, at any time on or before Completion, a member

of the same group as, or otherwise associated or connected with, the member of the Target

Group concerned; and (ii) is not a member of the Target Group or any other member of

the Purchasers’ Group, provided that such person was, at the time when such thing was

done, within the control of the Sellers’ Group.

14.3 Subject to paragraph 14.7, each

relevant Purchaser shall pay to the relevant Seller(s) an amount equal to the Relevant

Proportion of any Tax Liability of a member of the Relevant Seller Group in respect of Tax

which is chargeable directly or primarily against, or arises directly or primarily in consequence

of or by reference to anything done by, any member of the Purchasers’ Group. No payment

shall be due under this paragraph 14.3 to the extent that, had the Tax in question

been discharged by the relevant member of the Purchasers’ Group (and ignoring for this

purpose any financial or time limits), the relevant Purchaser would have been entitled to

make a Claim against that Seller under this Schedule 9 or under the Tax Warranties

in respect of such Tax; and, in such circumstances and to that extent, such Seller shall

procure that no statutory or other right to recover in respect of that Secondary Liability

shall be exercised.

14.4 If a payment is due under paragraphs

14.2 or 14.3, the payer shall also pay any reasonable out-of-pocket costs and

expenses reasonably and properly incurred by, in the case of a payment under paragraph

14.2, any member of the Purchasers’ Group or, in the case of a payment made under

paragraph 14.3, any member of the Sellers’ Group, to the extent in either case

that such costs and expenses would not have been so incurred but for any Secondary Liability

which gives rise to an obligation for the payer to make a payment under paragraphs 14.2

or 14.3 or with any Tax Authority Claim therefor; or in successfully taking or defending

any action under paragraphs 14.2 or 14.3.

14.5 Where a party is entitled to receive

an amount under this paragraph 14 and a person is or becomes entitled, under any statutory

provision or otherwise, to recover an amount in respect of the relevant Secondary Liability

other than pursuant to this paragraph 14, then such party shall use, or shall procure

that the relevant person uses, all reasonable endeavours to make such recovery. In the event

that such recovery is made, such payments shall be made between the parties as will ensure

that the aggregate amount paid by the paying party or parties under this paragraph 14

is equal to the amount that would have been so payable but for this paragraph 14.5

minus the amount of such recovery, net of any Taxes and out-of-pocket costs and expenses

incurred in making such recovery (provided that such aggregate amount shall not be less than

zero).

177

14.6 Paragraphs 10 and 13 shall

apply to the covenant in this paragraph 14 as if references to the relevant Purchaser(s) were

replaced with references to the relevant Seller(s) or other applicable terms (and vice

versa) and “Purchasers’ Relief” were replaced with “Relief other

than a Purchasers’ Relief” and making any other necessary modifications.

14.7 The exclusions in paragraph 3

shall apply to the covenants in paragraphs 14.2 and 14.3, making any necessary

modifications.

15. Notional End of Tax Period

15.1 For the purposes of determining whether

a Tax Liability, Relief, or entitlement to or receipt of a repayment of Tax has arisen in

respect of a period ending on or before Completion or in respect of a period commencing after

Completion, a Tax Period of each member of the Target Group current at the time of Completion

shall be deemed to end at that time.

16. Cooperation on Tax Matters

16.1 Without prejudice to the foregoing provisions

in this Schedule 9, the Parties shall cooperate, as and to the extent reasonably requested

by another such Party, in connection with determining any Tax Liability, the preparation

and filing of any Tax Return under this Schedule 9, and any audit, litigation or other

proceeding or Action with respect to Taxes, in each case, relating to any member of the Target

Group with regard to any Pre-Completion Tax Period. Such cooperation shall include (upon

the other Party’s written request) the provision of records and information that are

reasonably relevant to any such Tax matter and making employees reasonably available on a

mutually convenient basis to provide additional information and explanation of any material

provided hereunder.

17. Miscellaneous

17.1 No amount of any Tax Liability, Relief

or repayment of Tax shall be counted more than once in either Party’s favour (whether

to give rise to or increase an amount due to them or to eliminate or reduce an amount due

from them) pursuant to this Schedule 9, treating for this purpose the members of the

Purchasers’ Group (including the Target Group) together as one party.

17.2 Notwithstanding anything to the contrary

in this Agreement, in the event of a conflict or inconsistency between the provisions of

this Schedule 9 and any other provisions of this Agreement, the provisions of this

Schedule 9 shall govern.

to Tidewater. The WSUT fleet of 22 PSVs is an excellent complement to the Tidewater fleet and further expands our leading global market

Forward-Looking Statements

In accordance with the safe harbor provisions of the Private Securities

Litigation Reform Act of 1995, the Company notes that certain statements set forth in this communication are forward-looking statements

which reflect our current view with respect to future events and future financial performance. Forward-looking statements are all statements

other than statements of historical fact, including, without limitation, statements about the expected benefits of the WSUT acquisition

and our ability to integrate its operations and business successfully. All such forward-looking statements are subject to risks and uncertainties,

many of which are beyond the control of the Company, and our future results of operations could differ materially from our historical

results or current expectations reflected by such forward-looking statements. These risks and uncertainties include, without limitation:

potential adverse reactions or changes to business relationships resulting from the completion of the transaction; the effects of disruption

to our business; the effects of industry, market, economic, political or regulatory conditions outside of our control; transaction costs;

our ability to achieve the benefits from the transaction, including the anticipated cash flow generation and customer relationships; our

ability to promptly, efficiently and effectively integrate the vessels into our own operations; unknown liabilities; and the diversion

of management time on integration-related issues. Other important factors that could cause actual results to differ materially from those

in the forward-looking statements include: fluctuations in worldwide energy demand and oil and gas prices; fleet additions by competitors

and industry overcapacity; limited capital resources available to replenish our asset base as needed, including through acquisitions or

vessel construction, and to fund our capital expenditure needs; uncertainty of global financial market conditions and potential constraints

in accessing capital or credit if and when needed with favorable terms, if at all; changes in decisions and capital spending by customers

based on industry expectations for offshore exploration, field development and production; consolidation of our customer base; loss of

a major customer; changing customer demands for vessel specifications, which may make some of our older vessels technologically obsolete

for certain customer projects or in certain markets; rapid technological changes; delays and other problems associated with vessel maintenance;

the continued availability of qualified personnel and our ability to attract and retain them; the operating risks normally incident to

our lines of business, including the potential impact of liquidated counterparties; our ability to comply with covenants in our indentures

and other debt instruments; acts of terrorism and piracy; the impact of regional or global public health crises or pandemics; the impact

of potential information technology, cybersecurity or data security breaches; integration of acquired businesses and entry into new lines

of business; disagreements with our joint venture partners; natural disasters or significant weather conditions; unsettled political conditions,

war, civil unrest and governmental actions, such as expropriation or enforcement of customs or other laws that are not well developed

or consistently enforced; risks associated with our international operations, including local content, local currency or similar requirements

especially in higher political risk countries where we operate; interest rate and foreign currency fluctuations; labor changes proposed

by international conventions; increased regulatory burdens and oversight; changes in laws governing the taxation of foreign source income;

retention of skilled workers; enforcement of laws related to the environment, labor and foreign corrupt practices; increased global concern,

regulation and scrutiny regarding climate change; increased stockholder activism; the potential liability for remedial actions or assessments

under existing or future environmental regulations or litigation; the effects of asserted and unasserted claims and the extent of available

insurance coverage; the resolution of pending legal proceedings; and other risks and uncertainties detailed in our most recent Form 10-K,

Form 10-Qs and Form 8-Ks filed with or furnished to the Securities and Exchange Commission. If one or more of these or other risks or

uncertainties materialize (or the consequences of any such development changes), or should our underlying assumptions prove incorrect,

actual results or outcomes may vary materially from those reflected in our forward-looking statements. Statements in this communication

are made as of the date hereof, and the Company disclaims any intention or obligation to update publicly or revise such statements, whether

as a result of new information, future events or otherwise.
