which an election to receive Parent Common Stock as consideration (a “Common Stock Election”) is properly made (or deemed to have been made), and not revoked, in accordance with Section 2.3, 6.292 shares of

 12

thereafter cease to be a limited partner of NAP or have any rights with respect to such NAP Public Unit, except the right to receive the Merger Consideration and any dividends or distributions to which former Holders of NAP Public Units become
entitled all in accordance with this Article II upon the Surrender of (A) a certificate that immediately prior to the Effective Time represented NAP Public Units (a “NAP Certificate”) or (B) uncertificated

Section 2.2. 
 (iii) Treatment of NAP-Owned Units and Parent-Owned
Partnership Interests. Any NAP Common Units that are owned immediately prior to the Effective Time by any NAP Group Entity shall be automatically canceled and shall cease to exist and no consideration shall be delivered in exchange for such
canceled, NAP Common Units (“NAP Cancelled Units”). All (A) NAP General Partner Interest (B) General Partner Units, (C) NAP Common Units that are not NAP Public Units and are not cancelled pursuant to the first
sentence of this clause (iii) and (D) NAP Incentive Distribution Rights shall, in each case, remain outstanding as partnership interests in the Surviving Entity, unaffected by the Merger. 

(iv) Equity of Merger Sub. The outstanding limited liability company interest in Merger Sub issued and outstanding immediately prior to
the Effective Time shall be converted into an aggregate number of Common Units (as defined in the Amended NAP Partnership Agreement) of the Surviving Entity equal to the number of NAP Public Units that are converted into the right to receive the
Merger Consideration pursuant to Section 2.1(c)(i). At the Effective Time, the books and records of NAP shall be revised to reflect the cancellation and retirement of all NAP Public Units and the conversion of the limited
liability company interest in Merger Sub into Common Units (as defined in the Amended NAP Partnership Agreement) of the Surviving Entity, and the existence of NAP (as the Surviving Entity) shall continue without dissolution. 

(d) Other Effects of the Merger. The Merger shall be conducted in accordance with and shall have the effects set forth in this Agreement
and the applicable provisions of Marshall Islands Limited Liability Company Act and the Marshall Islands Limited Partnership Act. From and after the Effective Time, the certificate of limited partnership of NAP shall remain unchanged and shall
continue as the certificate of limited partnership of the Surviving Entity until duly amended in accordance with applicable Law and the terms of the NAP Partnership Agreement. At the Effective Time, by virtue of the Merger, the NAP Partnership
Agreement shall be automatically amended as set forth in Exhibit B (the NAP Partnership Agreement as so amended, the “Amended NAP Partnership Agreement”), and from and after the Effective Time, as so amended, shall be the
agreement of limited partnership of the Surviving Entity until duly further amended in accordance with applicable Law and the terms of the Amended NAP Partnership Agreement. 

  
 13 

 (e) No Fractional Shares. Notwithstanding any other provision of this Agreement,
(i) no certificates or scrip representing fractional shares of Parent Common Stock shall be issued in the Merger, (ii) each Holder of NAP Public Units exchanged pursuant to the Merger who would otherwise have been entitled to receive a
fractional share of Parent Common Stock (after taking into account all NAP Public Units held by such Holder immediately prior to the Effective Time) of 0.5 or above shall receive from Parent, in lieu of such fractional share, a full share of Parent
Common Stock, and (iii) any Holder of NAP Public Units exchanged pursuant to the Merger who would otherwise have been entitled to receive a fractional share of Parent Common Stock (after taking into account all NAP Public Units held by such
Holder immediately prior to the Effective Time) of less than 0.5 shall receive no consideration for such fraction share, which shall be forfeited.

Agreement, the number of outstanding NAP Common Units or shares of Parent Common Stock shall be changed into a different number of units, shares or other securities (including any different class or series of securities) by reason of any dividend or
distribution payable in partnership interests, equity interests or Rights, subdivision, reclassification, split, split-up, combination, merger, consolidation, or other similar transaction, or any such
transaction shall be authorized, declared or agreed upon with a record date at or prior to the Effective Time, in each case other than the Parent Reverse Stock Split, then the Common Stock Election Consideration and the initial “Conversion
Rate” set forth and defined in the Certificate of Designation, and any other similarly dependent items shall be appropriately adjusted to reflect fully the effect of such transaction and to provide to Parent, NAP, Merger Sub and the Holders of
NAP Public Units the same economic effect as contemplated by this Agreement prior to such event, and thereafter, all references in this Agreement to the Merger Consideration, and any other similarly dependent items shall be references to the Common
Stock Election Consideration and/or the initial Conversion Rate set forth and defined in the Certificate of Designation, and any other similarly dependent items, as so adjusted; provided, however, that nothing in this
Section 2.1(f) shall be deemed to permit or authorize any party hereto to effect any such dividend or distribution payable in partnership interests, equity interests or Rights, subdivision, reclassification, split, split
up, combination, merger, consolidation or other similar transaction, or the authorization, declaration or agreement to do such transaction that it is not otherwise authorized or permitted to be undertaken pursuant to this Agreement.

Transmittal”) (which shall specify that delivery shall be effected, and risk of loss and title to the NAP Certificates shall pass, only upon proper delivery of the NAP Certificates (or lost certificate affidavit as contemplated by this
Section 2.2(b)) to the Exchange Agent or, in the case of Book-Entry NAP Common Units, upon adherence to the procedures set forth in the Letter of Transmittal, and which shall be in such customary form and have such other
provisions as Parent and NAP may reasonably agree prior to the Effective Time) and instructions for effecting the Surrender of such NAP Certificates (or lost certificate affidavit as contemplated by this Section 2.2(b)) or
Book-Entry NAP Common Units in exchange for, as applicable, whole shares of Parent Issued Stock and any dividends or distributions payable pursuant to Section 2.2(c) or Section 2.2(d). Subject to
Section 2.2(c), upon Surrender to the Exchange Agent of such NAP Certificates (or lost certificate affidavit as contemplated by this Section 2.2(b)) or Book-Entry NAP Common Units, together with
such properly completed and duly executed Letter of Transmittal and such other documents as may reasonably be required by the Exchange Agent, the Holder of an NAP Certificate (or lost certificate affidavit as contemplated by this
Section 2.2(b)) or Book-Entry NAP Common Units shall be entitled to receive in exchange therefor, as applicable, (i) that number and type of whole shares of Parent Issued Stock (which shall be in uncertificated
book-entry form unless a physical certificate is requested) to which such Holder is entitled pursuant to Sections 2.1(c)(i) and 2.1(e), and (ii) any dividends or distributions payable pursuant to
Section 2.2(c) or Section 2.2(d) to which such Holder is entitled. The instructions for effecting the Surrender of NAP Certificates shall set forth procedures that must be taken by the Holder of
any NAP Certificate that has been lost, destroyed or stolen; it shall be a condition to the right of such Holder to receive the Merger Consideration and any dividends or distributions payable pursuant to Section 2.2(c) or
Section 2.2(d) that the Exchange Agent shall have received, along with the Letter of Transmittal, a duly executed lost certificate affidavit, including an agreement to indemnify Parent, signed exactly as the name or names
of the registered Holder or Holders of NAP Public Units appeared on the books of NAP immediately prior to the Effective Time, together with a customary bond and such other documents, in each case, as Parent may reasonably require in connection
therewith. After the Effective Time, there shall be no further transfer on the records of NAP or its transfer agent of NAP Certificates or Book-Entry NAP Common Units (provided, however, that the foregoing shall not restrict the
transfer of any NAP Partnership Interest other than the NAP Public Units after the Effective Time); and if such NAP Certificates or Book-Entry NAP Common Units are presented to NAP or its transfer agent for transfer, they shall be canceled against
delivery of the appropriate Merger Consideration and any dividends or distributions payable pursuant to Section 2.2(c) or Section 2.2(d) as hereinabove provided. Until Surrendered as contemplated
by this Section 2.2(b) or in connection with an Election made pursuant to Section 2.3, each NAP Certificate or Book-Entry NAP Common Unit shall be deemed at
any time after the Effective Time to represent only the right to receive upon such Surrender the appropriate Merger Consideration. No interest will be paid or will accrue on any dividends or distributions payable pursuant to
Section 2.2(c) or Section 2.2(d). 
 (c) Dividends and Distributions with Respect to
Unexchanged NAP Public Units. No dividends or other distributions with respect to shares of Parent Issued Stock issued in the Merger with a record date after the Effective Time shall be paid to the Holder of any NAP Certificate or Book-Entry NAP
Common Units not Surrendered with respect to such shares of 

  
 15 

 
Parent Issued Stock issuable in respect thereof until the Surrender of such NAP Certificate or Book-Entry NAP Common Units in accordance with this Section 2.2. Subject
to the effect of applicable Law, Parent shall pay, or cause the Exchange Agent to pay, to the Holder of each NAP Certificate or Book-Entry NAP Common Units, without interest, (i) at the time of Surrender of such NAP Certificate or Book-Entry
NAP Common Units, the amount of dividends or other distributions previously paid with respect to the whole shares of Parent Issued Stock issuable with respect to such NAP Certificate or Book-Entry NAP Common Units that have a record date after the
Effective Time and a payment date on or prior to the time of Surrender and (ii) at the appropriate payment date, the amount of dividends and distributions payable with respect to such whole shares of Parent Issued Stock with a record date after
the Effective Time and prior to such Surrender and a payment date subsequent to such Surrender. 
 (d) No Further Ownership Rights in NAP
Public Units. All Merger Consideration issued upon the Surrender for exchange of NAP Certificates or Book-Entry NAP Common Units in accordance with the terms of this Article II shall be deemed to have been issued (and paid) in full
satisfaction of all rights pertaining to the NAP Public Units heretofore represented by such NAP Certificates or Book-Entry NAP Common Units, subject, however, to Parent’s obligation, notwithstanding the conversion of NAP Public Units pursuant
to this Agreement, with respect to NAP Public Units outstanding immediately prior to the Effective Time, to pay (or cause NAP to pay) to the Holder of NAP Public Units as of the applicable record date any distributions with a record date at or prior
to the Effective Time that may have been declared or made by NAP or the NAP General Partner with respect to such NAP Common Units in accordance with the terms of the NAP Partnership Agreement on or prior to the Effective Time and that remain unpaid
at the Effective Time. 
 (e) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the Holders
of the NAP Certificates or Book-Entry NAP Common Units for six months after the Closing Date shall be delivered to Parent, upon demand, and any Holders of the NAP Certificates or Book-Entry NAP Common Units who have not theretofore complied with
this Section 2.2 shall thereafter look only to Parent and only as general creditors thereof for payment of their claim for the Merger Consideration and any dividends and distributions with respect to NAP Common Units or
shares of Parent Common Stock to which such holders may be entitled. 
 (f) No Liability. To the extent permitted by applicable Law,
none of Parent, Merger Sub, NAP, NAP General Partner or the Exchange Agent shall be liable to any Person in respect of any Merger Consideration or distribution properly delivered to a public official pursuant to any applicable abandoned property,
escheat or similar Law. If any NAP Certificates or Book-Entry NAP Common Units shall not have been Surrendered immediately prior to such date on which any Merger Consideration, or any dividends or distributions with respect to the NAP Common Units
or shares of Parent Issued Stock in respect of such NAP Certificate or Book-Entry NAP Common Units would escheat to or become the property of any Governmental Entity, any such units, cash or distributions in respect of such NAP Certificates or
Book-Entry NAP Common Units shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto. 

  
 16

To the extent that amounts are so withheld or paid over to or deposited with the relevant Governmental Entity by Parent, Merger Sub, NAP, the Surviving Entity or the Exchange Agent, such amounts
shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made by Parent, Merger Sub, NAP, the Surviving Entity or the Exchange Agent, as the case may be. 

(h) No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or
the other transactions contemplated by this Agreement. 
 SECTION 2.3 Election Procedures. 

(a) On the date the NAP Information Statement is mailed pursuant to Section 5.2, Parent shall, or shall cause the
Exchange Agent to, mail to each Holder of NAP Public Units receiving the NAP Information Statement pursuant to Section 5.2, an election form, prepared by Parent and reasonably acceptable to the NAP Conflicts Committee (the
“Election Form”), pursuant to which a holder of NAP Public Units may make an Election as specified in Section 2.3(c). The Election Form shall set forth instructions for making an Election and effecting the
Surrender of NAP Certificates and Book-Entry NAP Common Units in connection with the making of an Election, shall specify that delivery shall be effected, and risk of loss and title to the NAP Certificates shall pass, and an Election shall be
properly made in respect of NAP Public Units, only upon proper delivery of the NAP Certificates (or lost certificate affidavit as contemplated by this Section 2.3(a)) to the Exchange Agent or, in the case of Book-Entry NAP
Common Units, upon adherence to the procedures set forth in the Election Form, and shall otherwise be in such customary form and have such other provisions as Parent and NAP may reasonably agree. The Election Form shall set forth procedures that
must be taken by the Holder of any NAP Certificate that has been lost, destroyed or stolen; it shall be a condition to the right of such Holder to make an Election, to deliver, along with the Election Form, a duly executed lost certificate
affidavit, including an agreement to indemnify Parent, signed exactly as the name or names of the registered Holder or Holders of NAP Public Units appeared on the books of NAP immediately prior to the Effective Time, together with a customary bond
and such other documents, in each case, as Parent may reasonably require in connection therewith. 
 (b) Parent shall make available one or
more Election Forms as may reasonably be requested from time to time by all Persons who become Holders of NAP Public Units prior to the Election Deadline. NAP shall provide to the Exchange Agent all information reasonably necessary for it to perform
the obligations specified in this Section 2.3 and as specified in any agreement among the parties and the Exchange Agent. 

  
 17 

 (c) Each Holder of NAP Public Units shall be entitled, with respect to all or any portion of
the NAP Public Units held by such Person, to make, prior to the Election Deadline, an election (an “Election” and the act of making an Election, “Elect”) specifying (x) the number of such Holder’s NAP
Public Units with respect to which such Holder makes a Common Stock Election (each NAP Public Unit in respect of which a Holder properly makes, and does not revoke, a Common Stock Election in accordance with this
Section 2.3 (for avoidance of doubt, excluding all deemed Elections pursuant to the last sentence of this Section 2.3(c)), a “Common Stock Election Unit”, and the aggregate number
of Common Stock Election Units, the “Common Stock Election Total”); and (y) the number of such holder’s NAP Public Units with respect to which such holder makes a Preferred Stock Election (each NAP Public Unit in respect
of which a holder properly makes, and does not revoke, a Preferred Stock Election in accordance with this Section 2.3 (for avoidance of doubt, excluding all deemed Elections pursuant to the last sentence of this
Section 2.3(c)), a “Preferred Stock Election Unit”, and the aggregate number of Preferred Stock Election Units, the “Preferred Stock Election Total”). Any NAP Public Units with respect to
which no Election shall have properly been made (or, if an Election shall have been made, shall have been revoked and not properly remade) prior to the Election Deadline shall be deemed for purposes of Section 2.1(c)(i) to
have been made as a Common Stock Election with respect to such NAP Public Units, if the Common Stock Election Total exceeds the Preferred Stock Election Total, or a Preferred Stock Election, if the Common Stock Election Total exceeds the Preferred
Stock Election Total. 
 (d) Except as otherwise expressly provided herein, an Election shall be effective only if the Exchange Agent shall
have received, no later than 5:00 p.m. New York time two (2) Business Days prior to the Closing Date (or such later date as Parent and NAP shall agree) (the “Election Deadline”) (i) an Election Form covering the NAP Public
Units to which such Election applies, executed and completed in accordance with the instructions set forth therein, and (ii) the Surrender to the Exchange Agent of the NAP Certificates and/or Book-Entry NAP Common Units to which such Election
Form applies.An Election may be revoked only by delivering to the Exchange Agent, prior to the Election Deadline, a written notice of revocation or a properly completed revised Election Form that identifies the NAP Public Units to which such revised
Election Form applies. The proper delivery to the Exchange Agent prior to the Election Deadline of a revised Election Form with respect to any NAP Public Units shall result in the revocation of all prior Election Forms with respect to all such NAP
Public Units. Subject to the terms of this Agreement, and of the Election Form, the Exchange Agent, in consultation with both Parent and NAP, shall have reasonable discretion to determine whether any election, revocation or change has been properly
or timely made and to disregard immaterial defects in the Election Forms, and any good faith decision of the Exchange Agent regarding such matters shall be binding and conclusive. None of Parent, NAP or the Exchange Agent shall be under any
obligations to notify any Person of any defect in an Election Form. Parent shall use reasonable efforts to announce the Election Deadline at least five (5) Business Days prior to the Election Deadline. Upon mutual agreement of Parent and NAP in
writing on or prior to the Closing Date (but in all events before the 5:00 P.M. New York City Time on the last Business Day prior to the Closing Date), Election Forms submitted after the Election Deadline may be accepted and the Elections subject
thereto treated as proper, but only so long as all properly completed late Election Forms received by the Exchange Agent before the time specified in such writing for acceptance of late Election Forms (the “Late Election Time”) are
accepted and treated as effective. The Late Election Time must be a time at least one (1) hour after the execution of the writing in which Parent and NAP agree to accept such late Election Forms and will be no later than the Effective Time.
Parent and NAP shall have no obligation to publicly announce or otherwise give notice to holders of NAP Public Units that a Late Election Time has been fixed or that late Election Forms will be accepted. Neither Parent nor

  
 18 

 
NAP shall be under any obligation to agree to accept any late Election Forms, and a determination to agree to accept any late Election Forms shall be made in the sole and absolute discretion of
each of Parent and NAP. No late Election Forms will be accepted and the Elections subject thereto shall not be treated as having been properly made, unless Parent and NAP mutually agree to such treatment in writing in accordance with, and as
expressly provided in, this Section 2.3(d). For the avoidance of doubt, any act, determination or agreement by NAP shall be made after consultation with, and in a manner consistent with the advice of, the NAP Conflicts
Committee. 
 SECTION 2.4 Plan of Reorganization. For purposes of the Intended Tax Treatment, this Agreement
constitutes, and is adopted as, a “plan of reorganization” for purposes of Sections 354 and 361 of the Code.

(a) As of June 30, 2018, the outstanding capitalization of NAP consists of 20,947,418 NAP Common Units, the NAP General Partner Interest,
represented by 427,499 NAP General Partner Units and the NAP Incentive Distribution Rights. All of such NAP Common Units and the NAP Incentive Distribution Rights and the limited partner interests represented thereby, have been duly authorized and

 21 

 SECTION 3.5 SEC Documents; Internal Controls. 

(a) Since January 1, 2016, all reports, including but not limited to the Annual Reports on Form
20-F and the Reports on Form 6-K (whether filed on a voluntary basis or otherwise), forms, schedules, certifications, prospectuses, registration statements and other
documents required to be filed or furnished by NAP or any NAP Subsidiary with or to the SEC have been or will be timely filed or furnished (the “NAP SEC Reports”). Each of the NAP SEC Reports (i) complied in all material
respects with the requirements of applicable Law (including the Exchange Act, the Securities Act and the Sarbanes-Oxley Act of 2002, as amended, and the rules and regulations promulgated thereunder (the “Sarbanes-Oxley Act”)), and
(ii) as of its effective date (in the case of NAP SEC Reports that are registration statements filed pursuant to the requirements of the Securities Act) and as of its filing date did not contain any untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except for any statements in any NAP SEC Report that may have
been modified by an amendment to such report or a subsequent report filed with the SEC prior to the Execution Date. 
 (b) NAP makes and
keeps books, records, and accounts and has devised and maintains a system of internal controls, in each case, as required pursuant to Section 13(b)(2) under the Exchange Act. NAP has established and maintains disclosure controls and procedures
and internal control over financial reporting (as such terms are defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) as required by Rule
13a-15 under the Exchange Act and the applicable listing standards of the NYSE. Such disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed
by NAP in the reports that it files under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated
to its management as appropriate to allow timely decisions regarding required disclosure. NAP General Partner’s principal executive officer and its principal financial officer have disclosed, based on their most recent evaluation, to NAP’s
auditors and the audit committee of the NAP Board (x) all significant deficiencies in the designation or operation of internal controls which could adversely affect NAP’s ability to record, process, summarize and report financial data and
have identified for NAP’s auditors any material weakness in internal controls and (y) any fraud, whether or not material, that involves management or other employees who have a significant role in NAP’s internal controls. 

(c) Since January 1, 2016, the principal executive officer and principal financial officer of the NAP General Partner have made all
certifications (without qualification or exceptions to the matters certified, except as to knowledge) required by the Sarbanes-Oxley Act, and the statements contained in any such certifications are complete and correct, and none of such entities or
its officers have received notice from any Governmental Entity questioning or challenging the accuracy, completeness, form or manner of filing or submission of such certification. As of the Execution Date, and except as disclosed in a NAP SEC Report
filed with the SEC prior to the Execution Date, none of such entities has any knowledge of any material weakness in the design or operation of such internal controls over financial reporting. 

  
 22 

 SECTION 3.6 Financial Statements; Undisclosed Liabilities.

December 31, 2016 and December 31, 2015 and consolidated audited balance sheets as of December 31, 2017 and as of December 31, 2016 for NAP, including the notes thereto and NAP’s Report on Form
6-K (“Latest NAP Quarter 6-K”) filed with the SEC on August 2, 2018 sets forth a true and correct copy of the consolidated unaudited statements of
operations, cash flows and changes in partners’ capital for the six month periods ended June 30, 2018 and June 30, 2017 and consolidated unaudited balance sheet as of June 30, 2018 for NAP, including the notes thereto (the
referenced financial statements set forth in the NAP 20-F and the Latest NAP Quarter 6-K are collectively referred to as the “NAP Financial

respects the consolidated financial position of NAP as of the dates indicated therein and the consolidated results of operations and cash flows of NAP for the periods indicated therein, except as otherwise noted therein. Except as set forth in the
NAP Financial Statements, there are no off-balance sheet arrangements that would, individually or in the aggregate, have a NAP Material Adverse Effect. NAP has not had any disagreement with its independent
public accounting firm that required disclosure in the NAP SEC Reports. 
 (b) There are no liabilities or obligations of NAP or the NAP
Subsidiaries (whether known or unknown and whether accrued, absolute, contingent or otherwise) of a type that are required by GAAP to be reflected or reserved against in a consolidated balance sheet of NAP, other than (i) liabilities or
obligations reflected or reserved against in the consolidated balance sheet as of June 30, 2018 included in the NAP Financial Statements, (ii) current liabilities incurred in the ordinary course of business since June 30, 2018, (iii)
liabilities and obligations incurred under or in accordance with this Agreement or in connection with the transactions contemplated by this Agreement, and (iv) liabilities or obligations (whether known or unknown and whether accrued, absolute,
contingent or otherwise) that would not, individually or in the aggregate, have an NAP Material Adverse Effect.

voting securities or other equity interests of Parent issued or granted by, or binding upon, Parent, except for awards granted under Parent’s employee benefit, stock option, incentive and stock purchase plans, or as expressly contemplated by

 (b)
The shares of Parent Common Stock and Parent Preferred Stock issued and outstanding as of June 30, 2018, were, and the shares of Parent Issued Stock to be issued pursuant to the Merger will, upon issuance, be, duly authorized, validly issued,

(a) Since January 1, 2016, all reports, including but not limited to the Annual Reports on Form
20-F, and the Reports on Form 6-K (whether filed on a voluntary basis or otherwise), forms, schedules, certifications, prospectuses, registration statements and other
documents required to be filed or furnished by Parent or any Parent Subsidiary with or to the SEC have been or will be timely filed or furnished (the “Parent SEC Reports”). Each of the Parent SEC Reports (i) complied in all
material respects with the requirements of applicable Law (including the Exchange Act, the Securities Act and the Sarbanes-Oxley Act), and (ii) as of its effective date (in the case of Parent SEC Reports that are registration statements filed
pursuant to the Securities Act) and as of its filing date did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading, except for any statements in any Parent SEC Report that may have been modified by an amendment to such report or a subsequent report filed with the SEC prior to the Execution Date. 

  
 30 

 (b) Parent makes and keeps books, records, and accounts and has devised and maintains a
system of internal controls, in each case, as required pursuant to Section 13(b)(2) under the Exchange Act. Parent has established and maintains disclosure controls and procedures and internal control over financial reporting (as such terms are
defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) as required by Rule 13a-15 under the Exchange Act and the applicable
listing standards of the NYSE. Such disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by Parent in the reports that it files under the Exchange Act are recorded, processed,
summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to its management as appropriate to allow timely decisions regarding required
disclosure. Parent’s principal executive officer and its principal financial officer have disclosed, based on their most recent evaluation, to Parent’s auditors and the audit committee of the Parent Board (x) all significant
deficiencies in the designation or operation of internal controls which could adversely affect Parent’s ability to record, process, summarize and report financial data and have identified for Parent’s auditors any material weakness in
internal controls and (y) any fraud, whether or not material, that involves management or other employees who have a significant role in Parent’s internal controls. 

(c) Since January 1, 2016, the principal executive officer and principal financial officer of Parent have made all certifications (without
qualification or exceptions to the matters certified, except as to knowledge) required by the Sarbanes-Oxley Act, and the statements contained in any such certifications are complete and correct, and none of such entities or its officers have
received notice from any Governmental Entity questioning or challenging the accuracy, completeness, form or manner of filing or submission of such certification. As of the Execution Date, and except as disclosed in a Parent SEC Report filed with the
SEC prior to the Execution Date, none of such entities has any knowledge of any material weakness in the design or operation of such internal controls over financial reporting. 

SECTION 4.6 Financial Statements; Undisclosed Liabilities.

“Parent 20-F”) sets forth a true and complete copy of the consolidated audited statements of operations, cash flows and changes in equity for each of years ended December 31, 2017,
December 31, 2016 and December 31, 2015 and consolidated audited balance sheets as of December 31, 2017 and as of December 31, 2016 for Parent, including the notes thereto and Parent’s Report on Form 6-K (“Latest Parent Quarter 6-K”) filed with the SEC on August 23, 2018 sets forth a true and correct copy of the consolidated unaudited statements of
operations, cash flows and changes in equity for the six month periods ended June 30, 2018 and June 30, 2017 and consolidated unaudited balance sheet as of June 30, 2018 for Parent, including the notes thereto (the referenced
financial statements set forth in the Parent 20-F and the Latest Parent Quarter 6-K are collectively referred to as the “Parent Financial Statements”).
The Parent Financial Statements have been prepared in accordance with GAAP applied on a consistent basis throughout the periods covered thereby (except as may be indicated in the notes thereto) and present fairly in all material respects the
consolidated financial position of Parent as of dates indicated therein and the consolidated results of operations and cash flows of Parent for the periods indicated therein, except as otherwise noted therein. Except as set forth in the Parent
Financial Statements, there are no off-balance sheet arrangements that would, individually or in the aggregate, have a Parent Material Adverse Effect. Parent has not had any disagreement with its independent
public accounting firm that required disclosure in the NAP SEC Reports.

Notwithstanding the foregoing, the parties hereby agree that, subject to receiving the requisite approval of the holders of Parent Common
Stock, Parent may implement the Parent Reverse Stock Split, including by amending Parent’s Governing Documents in order to reflect the Parent Reverse Stock Split, and no such implementation shall be deemed a violation or breach of this
Section 5.1, or of any other provision of this Agreement. 
 (c) From the Execution Date until the Closing Date,
each of Parent and NAP shall, and shall cause the NAP Group Entities (in the case of NAP) or Parent Group Entities (in the case of Parent) to, promptly notify the other party in writing of (i) any event, condition or circumstance that could
reasonably be expected to result in any of the conditions set forth in Article VI not being satisfied at the Effective Time, and (ii) any material breach by the notifying party of any covenant, obligation, or agreement
contained in this Agreement; provided, however, that the delivery of any notice pursuant to this Section 5.1(c) shall not limit or otherwise affect the remedies available hereunder to the notified party. 

SECTION 5.2 Certain Filings; No Solicitation; Recommendation of Merger; Commitment to Vote. 

(a) As promptly as practicable following the Execution Date (i) Parent and NAP shall jointly prepare the Registration Statement, which
shall include a prospectus with respect to the shares of Parent Issued Stock in the Parent Stock Issuance and to be issued and an information statement to be provided to the Holders of NAP Common Units (the “NAP Information
Statement”), (ii) Parent shall file the Registration Statement with the SEC, (iii) Parent shall use its reasonable efforts to cause the shares of Parent Common Stock and, subject to Section 5.12, the shares of
Parent Series E Preferred Stock to be issued in the Merger to be approved for listing on the NYSE (subject, if applicable, to notice of issuance) prior to the Effective Time, and (iv) the parties hereto shall make all required filings under
applicable state securities and “blue sky” Laws; provided, however, that no such filings shall be required in any jurisdiction where, as a result thereof, Parent would become subject to general service of process or to
taxation or qualification to do business as a foreign corporation doing business in such jurisdiction solely as a result of such filing. No filing of, or amendment or supplement to, the Registration Statement or the NAP Information Statement will be
made by Parent without providing NAP a reasonable opportunity to review and comment thereon. Each of Parent and NAP agrees to use its reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act as
promptly as practicable after filing thereof and keep the Registration Statement effective until the earlier of the consummation of the transactions contemplated by this Agreement and the termination of this Agreement in accordance with its terms
and the NAP General Partner shall promptly thereafter mail the NAP Information Statement to the Holders of NAP Common Units. Each of Parent and NAP agrees to furnish to the other party all information concerning the Parent Group Entities or the NAP
Group Entities, as applicable, and to take such other action as may be reasonably requested in connection with the foregoing. 

  
 38 

 (b) Each of Parent and NAP agrees, as to itself and its Subsidiaries, that (i) none of
the information supplied or to be supplied by it for inclusion or incorporation by reference in the Registration Statement will, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the
Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) and (ii) none of the information supplied or
to be supplied by it for inclusion or incorporation by reference in the NAP Information Statement and any amendment or supplement thereto will, at the date the NAP Information Statement is mailed to the Holders of NAP Common Units, contain any
untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of Parent and NAP further agrees that, if it
shall become aware prior to the Closing Date of any information that would cause any of the statements in the Registration Statement or the NAP Information Statement to be false or misleading with respect to any material fact, or omit to state any
material fact necessary to make the statements therein, in light of the circumstances under which they were made, not false or misleading, it will promptly inform the other party thereof and take the necessary steps to correct such information in an
amendment or supplement to the Registration Statement or the NAP Information Statement. 
 (c) Each of NAP and Parent shall (i) promptly
notify the other of receipt of any comments from the SEC or its staff or any other applicable government official and of any requests by the SEC or its staff or any other applicable government official for amendments or supplements to any of the
filings with the SEC in connection with the Merger and other transactions contemplated hereby or for additional information and (ii) promptly supply the other with copies of all correspondence between NAP or any of its representatives, or
Parent or any of its representatives, as the case may be, on the one hand, and the SEC or its staff or any other applicable government official, on the other hand, with respect thereto. Parent and NAP shall use their respective commercially
reasonable efforts to respond to any comments of the SEC or its staff with respect to the Registration Statement as promptly as practicable. 

(d) The parties shall distribute to the Holders of NAP Common Units the NAP Information Statement as promptly as practicable after the
Registration Statement is declared effective under the Securities Act. 
 (e) [Reserved]. 

(f) [Reserved]. 
 (g) Prior
to the earlier to occur of the termination of this Agreement or the Effective Time, (i) within two Business Days after the Registration Statement becomes effective under the Securities Act (but, for the avoidance of doubt, not until such
Registration Statement becomes effective), Parent shall deliver, and shall cause each Parent Group Entity that is a Holder of NAP Common Units to deliver (in its capacity as such), a written consent in accordance with Section 13.11 and
Section 14.3 of the NAP Partnership Agreement (and which shall constitute the NAP Written Consent) with respect to all of the NAP Common Units held by Parent and each Parent Group Entity approving this Agreement, the Merger and the other
transactions contemplated hereby and (ii) at every meeting of the Holders of NAP Common Units called, and at every adjournment or postponement thereof, and on every action or approval by written consent of the Holders of NAP Common Units,
Parent shall, and shall cause each other Parent Group Entity that is a Holder of Common Units (in their respective capacities as such) to, appear at such meeting or 

  
 39 

 
otherwise cause the NAP Common Units to be held by them to be present thereat for purposes of establishing a quorum and vote such NAP Common Units, or cause such NAP Common Units to be voted,
(A) in favor of the adoption of this Agreement and the Merger and the other transactions contemplated hereby (collectively, the “Proposed Transaction”), to the extent that the consideration and approval of any transaction
included in the Proposed Transaction is presented at such meeting of the Holders of NAP Common Units or is otherwise presented for approval by written consent, and (B) against any other matter presented at such meeting or otherwise presented
for approval by written consent that would reasonably be expected to (1) result in the breach of any covenant, representation or warranty of NAP under this Agreement, (2) result in, or contribute to, any of the conditions to the
consummation of the Merger under this Agreement not being fulfilled, or (3) impede, frustrate, interfere with, delay, postpone or adversely affect the Proposed Transaction. 

SECTION 5.3 Commercially Reasonable Efforts; Further Assurances. From and after the Execution Date, upon
the terms and subject to the conditions hereof, each of the parties hereto shall use its commercially reasonable efforts to (i) take, or cause to be taken, all appropriate action, and to do or cause to be done, all things necessary, proper or
advisable under applicable Law to consummate and make effective the transactions contemplated by this Agreement as promptly as practicable and (ii) defend any lawsuits or other Proceedings, whether judicial or administrative, challenging this
Agreement or the consummation of the transactions contemplated by this Agreement or seek to have lifted or rescinded any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions
contemplated hereby, including the Merger. Without limiting the foregoing but subject to the other terms of this Agreement, the parties hereto agree that, from time to time, whether before, at or after the Closing Date, each of them will execute and
deliver, or cause to be executed and delivered, such instruments of assignment, transfer, conveyance, endorsement, direction or authorization as may be necessary to consummate and make effective the transactions contemplated by this Agreement.
Notwithstanding the foregoing, nothing in this Agreement will require any party hereto to hold separate or make any divestiture not expressly contemplated herein of any asset or otherwise agree to any restriction on its operations or other condition
in order to obtain any consent or approval or other clearance required by this Agreement. 
 SECTION 5.4 Public
Announcement. On the Execution Date, Parent and NAP shall issue a joint press release with respect to the execution of this Agreement and the Merger, which press release shall be reasonably satisfactory to Parent, NAP and the NAP
Conflicts Committee. From and after the Execution Date, neither NAP nor Parent shall issue any other press release or make any other public announcement concerning this Agreement or the transactions contemplated by this Agreement (to the extent not
previously issued or made in accordance with this Agreement) (other than public announcements at industry road shows and conferences or as may be required by applicable Law or by obligations pursuant to any listing agreement with the NYSE, in which
event the party making the public announcement or press release shall, to the extent practicable, notify Parent and NAP in advance of such public announcement or press release) without the prior approval of the other, which approval shall not be
unreasonably withheld, delayed or conditioned. 

  
 40 

 SECTION 5.5 Expenses. Whether or not the Merger is
consummated, all costs and expenses incurred in connection with this Agreement, including legal fees, accounting fees, financial advisory fees and other professional and non-professional fees and expenses,
shall be paid by the party hereto incurring such expenses, (i) except as otherwise set forth in Section 7.6 and (ii) except that Parent and NAP shall each pay for one-half
of (a) any filing fees with respect to the Registration Statement and (b) the costs of printing and mailing of the NAP Information Statement. 

SECTION 5.6 Regulatory Issues. NAP and Parent shall cooperate fully with respect to any filing, submission or
communication with a Governmental Entity having jurisdiction over the Merger. Such cooperation shall include each of the parties hereto: (i) providing, in the case of oral communications with a Governmental Entity, advance notice of any such
communication and, to the extent permitted by applicable Law, an opportunity for the other party to participate; (ii) providing, in the case of written communications, an opportunity for the other party to comment on any such communication and
provide the other with a final copy of all such communications; and (iii) complying promptly with any request for information from a Governmental Entity (including an additional request for information and documentary material), unless directed
not to do so by the other party hereto. All cooperation shall be conducted in such a manner so as to preserve all applicable privileges. 

SECTION 5.7 Tax Opinion. Parent and NAP shall cooperate with each other in obtaining, and shall use their respective
reasonable efforts to obtain, a tax opinion from Fried, Frank, Harris, Shriver & Jacobson LLP (“Parent Tax Counsel”) to NAP, dated as of the Closing Date, in form and substance reasonably satisfactory to NAP (and any
similar opinion to be attached as an exhibit to the Form S-4), substantially to the effect that for U.S. federal income tax purposes the Merger should be treated as a “reorganization” within the
meaning of Section 368(a) of the Code and for Parent to be treated as a corporation under Section 367(a) of the Code with respect to each transfer of property thereto in connection with the Merger (other than a transfer by a shareholder
that is a U.S. person and that holds 5% or more of Parent (within the meaning of Treasury Regulation Section 1.367(a)-3(b)(1)(i)) immediately following the Merger that does not enter into a five-year gain
recognition agreement in the form provided in Treasury Regulation Section 1.367(a)-8(c)) (the “Merger Tax Opinion”). Each of Parent and NAP shall use its reasonable efforts to deliver to
Parent Tax Counsel for purposes of the Merger Tax Opinion a “Tax Representation Letter,” dated as of the Closing Date (and, if requested, dated as of the date the Form S-4 shall have been declared
effective by the SEC), signed by an officer of Parent or NAP, as applicable, and containing representations of Parent or NAP, as applicable, in each case, as shall be reasonably necessary or appropriate to enable Parent Tax Counsel to render the
Merger Tax Opinion. Parent and NAP shall cooperate with each other and shall use their reasonable efforts to obtain the Intended Tax Treatment.

 SECTION 5.8 D&O Insurance. 

(a) For a period of six years after the Effective Time, to the fullest extent permitted under applicable Law, the Surviving Entity shall, and
Parent shall cause the Surviving Entity to, (i) indemnify and hold harmless against any reasonable costs or expenses (including reasonable attorneys’ fees and all other reasonable costs, expenses and obligations (including experts’
fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or
participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Proceeding arising from acts or omissions occurring at or prior to the Effective Time (including the transactions contemplated by
this Agreement), including any Proceeding relating to a claim for indemnification or advancement brought by an NAP D&O Indemnified Party), judgments, fines, losses, claims, damages or liabilities, penalties and amounts paid in settlement
(including all interest, assessments and other charges paid or payable in connection with or in respect of any thereof) in connection with any actual or threatened Proceeding arising from acts or omissions occurring at or prior to the Effective Time
(including the transactions contemplated by this Agreement), and, upon receipt by the Surviving Entity of an undertaking by or on behalf of the NAP D&O Indemnified Party to repay such amount if it shall be determined in a final and non-appealable judgment entered by a court of competent jurisdiction that the NAP D&O Indemnified Party is not entitled to be indemnified, provide advancement of expenses with respect to each of the foregoing
to, all NAP D&O Indemnified Parties and (ii) honor all rights to indemnification, advancement of expenses, elimination of liability and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time
(including the transactions contemplated by this Agreement) now existing in favor of the NAP D&O Indemnified Parties as provided in the Governing Documents of any NAP Group Entity, under applicable the Law of the Republic of the Marshall Islands
or otherwise, and shall ensure that the Governing Documents of NAP (or their successor entities) shall, for a period of six years following the Effective Time, contain provisions substantially no less advantageous with respect to indemnification,
advancement of expenses, elimination of liability and exculpation of their present and former directors and officers, than are set forth in the Governing Documents of NAP as of the Execution Date. Any right of an NAP D&O Indemnified Party
pursuant to this Section 5.8(a) shall not be amended, repealed, terminated or otherwise modified at any time in a manner that would adversely affect the rights of such NAP D&O Indemnified Party as provided herein, and
shall be enforceable by such NAP D&O Indemnified Party and their respective heirs and representatives against Parent, the Surviving Entity and their respective successors and assigns. 

(b) For a period of six years after the Effective Time, the Surviving Entity shall, Parent shall cause the Surviving Entity to, maintain
officers’ and directors’ liability insurance with a nationally reputable carrier covering each NAP D&O Indemnified Party who is or at any time prior to the Effective Time was covered by the existing officers’ and directors’
liability insurance applicable to the NAP Group Entities (“D&O Insurance”), on terms substantially no less advantageous to the NAP D&O Indemnified Parties, as applicable, than such existing insurance with respect to acts or
omissions, or alleged acts or omissions, at or prior to the Effective Time (whether claims, actions or other Proceedings relating thereto are commenced, asserted or claimed before or after the Effective Time); provided, however, that
the Surviving Entity shall not be required to pay an annual premium for the D&O Insurance for the NAP D&O Indemnified Parties in excess of 300% of the current annual premium currently paid by the NAP Group Entities for such insurance, but
shall purchase as much of such coverage as possible for such applicable 

  
 42 

 
amount. Parent shall have the right to cause such coverage to be extended under the applicable D&O Insurance by obtaining a six-year “tail”
policy on terms and conditions no less advantageous to the NAP D&O Indemnified Parties than the existing D&O Insurance, and such “tail” policy shall satisfy the provisions of this Section 5.8. 

(c) The provisions of this Section 5.8 shall survive the consummation of the Merger and the other transactions
contemplated by this Agreement for a period of six years and expressly are intended to benefit each of the NAP D&O Indemnified Parties; provided, however, that in the event that any claim or claims for indemnification or
advancement set forth in this Section 5.8 are asserted or made within such six-year period, all rights to indemnification and advancement in respect of any such claim or claims shall
continue until disposition of all such claims. The rights of any NAP D&O Indemnified Party under this Section 5.8 shall be in addition to any other rights such NAP D&O Indemnified Party may have under the Governing
Documents of any NAP Group Entity or applicable Law. 
 (d) In the event Parent or any of its successors or assigns (i) consolidates
with or merges into any other Person and shall not be the continuing or surviving entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then and in either such case, Parent
shall cause proper provision to be made so that its successors and assigns, as the case may be, shall assume the obligations set forth in this Section 5.8. 

SECTION 5.9 Dividends and Distributions. After the date of this Agreement until the Effective Time, each of Parent and
NAP shall coordinate with the other regarding the declaration of any dividends or distributions in respect of Parent Common Stock and NAP Common Units, as applicable, and the record dates and payment dates relating thereto, it being the intention of
the parties that Holders of NAP Common Units shall not receive, for any quarter, distributions both in respect of NAP Common Units and also dividends in respect of Parent Common Stock that they receive in exchange therefor in the Merger, but that
they shall receive for any such quarter, either (a) only distributions in respect of NAP Common Units or (b) only dividends in respect of Parent Issued Stock that they receive in exchange therefor in the Merger. Prior to the Effective
Time, but subject to the foregoing, the NAP Board shall determine and declare quarterly distributions in the ordinary course, including with timing consistent with past practice; provided, however, that the amount of the distribution
for the third quarter of 2018 shall not be less than the distribution declared by NAP with respect to the quarter ended June 30, 2018 without the prior written consent of the NAP Conflicts Committee, and any subsequent distribution shall be as
declared by the NAP Board. 
 SECTION 5.10 Litigation. NAP shall give Parent the opportunity to participate in the
defense or settlement of any securityholder litigation against NAP, the members of the NAP Board and/or the NAP General Partner, in each case, relating to the Merger, this Agreement or any of the transactions contemplated by this Agreement,
provided that NAP shall not be required to provide information if doing so would be reasonably expected to threaten the loss of any attorney-client privilege or other applicable legal privilege or protective doctrine; provided,
further, that NAP shall not settle any such litigation without the written consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed). 

  
 43 

 SECTION 5.11 Conflicts Committee. Prior to the Effective Time,
none of the NAP Group Entities shall, without the consent of the NAP Conflicts Committee, eliminate the NAP Conflicts Committee, or revoke or diminish the authority of the NAP Conflicts Committee, or remove or cause the removal of any director of
the NAP Board that is a member of the NAP Conflicts Committee either as a member of such board or such committee without the affirmative vote of the members of the NAP Board, including the affirmative vote of each of the other members of the NAP
Conflicts Committee. For the avoidance of doubt, this Section 5.11 shall not apply to the filling in accordance with the provisions of the applicable Governing Documents of any vacancies caused by the death, incapacity or
resignation of any director. 
 SECTION 5.12 Listing of Parent Series E Preferred Stock. Parent shall use its
reasonable efforts to cause the shares of Parent Series E Preferred Stock to be issued in the Merger to be approved for listing on the NYSE (subject, if applicable, to notice of issuance); provided that Parent shall have no obligation to
pursue or effect any such listing (x) unless Holders representing more than fifty percent (50%) of the NAP Public Units issued and outstanding shall have properly Elected, and not revoked such Election (or shall be deemed to have been Elected
pursuant to the final sentence of Section 2.3(c)) to receive Preferred Stock Election Consideration, as calculated as of 5:00 PM New York City time on the last Business Day prior to the Closing Date, or (y) if the NYSE
shall not permit such listing.

terminated by NAP (which termination may be effected by the NAP Conflicts Committee without the consent, authorization or approval of the NAP Board) at any time prior to the Effective Time if the Parent Parties shall have breached or failed to
perform any of their respective representations, warranties, covenants or agreements set forth in this Agreement (or if any of the representations or warranties of the Parent Parties set forth in this Agreement shall fail to be true), which breach
or failure (a) would (if it occurred or was continuing as of the Closing Date) give rise to the failure of a condition set forth in Section 6.3(a) (with or without the passage of time) and (b) is incapable of
being cured, or is not cured, by the Parent Parties prior to the Outside Date; provided that the right to terminate this Agreement pursuant to this Section 7.3 shall not be available to NAP if, at such time, the
condition set forth in Section 6.2(a) cannot be satisfied (with or without the passage of time).

VIII shall survive such termination; except that nothing herein shall relieve any party hereto from any liability for any intentional or willful and material breach by such party of any of its representations, warranties, covenants or
agreements set forth in this Agreement and all rights and remedies of a non-breaching party under this Agreement in the case of such intentional or willful and material breach, at law or in equity, shall be
preserved. 

  
 47 

 SECTION 7.6 Expenses. 

(a) If this Agreement is validly terminated by NAP pursuant to Section 7.3, then Parent shall pay to NAP (or its
designated Affiliate) by wire transfer of immediately available funds to an account designated by NAP an amount equal to the NAP Expenses, and such payment shall be made within five (5) Business Days after such termination.

transactions contemplated by this Agreement, and that, without these agreements, Parent and Merger Sub, on the one hand, and NAP and the NAP General Partner, on the other hand, would not enter into this Agreement. The parties acknowledge that
payment of the Parent Expenses or the NAP Expenses, as applicable, if, as and when required pursuant to this Section 7.6, shall constitute the sole and exclusive remedy with respect thereto, except as expressly set forth in
Section 7.5. 
 SECTION 7.7 Survival. None of the representations, warranties,
agreements, covenants or obligations in this Agreement or in any instrument delivered pursuant to this Agreement shall survive the consummation of the Merger, except for those covenants and agreements contained herein that by their terms apply or
are to be performed in whole or in part after the Effective Time. 
 SECTION 7.8 Enforcement of this Agreement.
The parties hereto acknowledge and agree that an award of money damages would be inadequate for any breach of this Agreement by any party and any such breach would cause the non-breaching parties
irreparable harm. Accordingly, the parties hereto agree that prior to the termination of this Agreement, in the event of any breach or threatened breach of this Agreement by one of the parties, the parties will also be entitled, without the
requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance, provided such party is not in material default hereunder. Subject to Section 7.6(c), such

action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought exclusively in a court of competent jurisdiction of the
Marshall Islands, and each of the parties hereby irrevocably consents to the exclusive jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest
extent permitted by Law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an

TO TRIAL BY JURY IN ANY LEGAL PROCEEDING (WHETHER IN CONTRACT OR TORT OR OTHERWISE) ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

SECTION 8.3 Entire Agreement; Amendments, Consents and Waivers. This Agreement and the exhibits and
schedules hereto and thereto constitute the entire agreement between and among the parties hereto pertaining to the subject matter hereof and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of
the parties, and there are no warranties, representations or other agreements between or among the parties in connection with the subject matter hereof except as set forth specifically herein or contemplated hereby. Except as expressly set forth in
this Agreement (including the representations and warranties set forth in Articles III and IV), (a) the parties acknowledge and agree that neither the NAP Group Entities nor any other Person has made, and the Parent Group

Entities or as to the accuracy or completeness of any information regarding any Parent Group Entity furnished or made available to any NAP Group Entity, and (c) NAP and the Parent Parties
shall not have or be subject to any liability to any Parent Group Entity or any other Person or any NAP Group Entity or any other Person, as applicable, or any other remedy in connection herewith, based upon the distribution to any Parent Group

applicable Law, prior to the Closing, any provision of this Agreement may be (a) consented to or waived in writing by the party benefited by the provision or (b) amended or modified at any time by an agreement in writing by the parties

(y) enforce this Agreement (including pursuant to Section 7.8)), must be approved by, in the case of consents, waivers, amendments or modifications, or such decisions or determinations, by the NAP Conflicts Committee.
No amendment, supplement, modification or waiver of this Agreement shall be binding unless executed in writing by the parties hereto. The failure of a party to exercise any right or remedy shall not be deemed or constitute a waiver of such right or
remedy in the future. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver constitute a continuing waiver unless
otherwise expressly provided. Notwithstanding anything in this Agreement to the contrary, following receipt of the NAP Written Consent, there shall be no amendment or change to the provisions of this Agreement which by applicable Laws or stock
exchange rule would require further approval by the Holders of NAP Public Units, as applicable, without such approval. 

SECTION 8.4 Binding Effect; No Third-Party Beneficiaries; and Assignment. This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective permitted successors and assigns. Nothing in this Agreement, express or implied, is intended to confer upon any Person other than the parties hereto and their respective permitted
successors and assigns, any rights, benefits or obligations hereunder, except (i) as provided in Section 5.8 and (ii) for the right of the Holders of NAP Common Units to receive the Merger Consideration. No party
hereto may assign, transfer, dispose of or otherwise alienate this Agreement or any of its rights, interests or obligations under this Agreement (whether by operation of law or otherwise). Any attempted assignment, transfer, disposition or
alienation in violation of this Agreement shall be null, void and ineffective. 

  
 51 

 SECTION 8.5 Severability. If any term or other provision of
this Agreement is invalid, illegal, or incapable of being enforced by any rule of applicable Law, or public policy, all other conditions or provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or
legal substance of the transactions contemplated by this Agreement are not affected in any matter materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced,
the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement
are consummated as originally contemplated to the fullest extent possible. 
 SECTION 8.6 Counterparts. This
Agreement may be executed in multiple counterparts each of which shall be deemed an original and all of which shall constitute one instrument.
