(i) On the Closing Date, concurrently with or as soon as practicable following the Closing, Parent and NAP shall cause a certificate of merger effecting the Merger (the “Certificate of Merger”) to be filed with the Office of the Registrar of Corporations of the Republic of the Marshall Islands, duly executed in accordance with the relevant provisions of the Marshall Islands Limited Liability Company Act and the Marshall Islands Limited Partnership Act (the date and time of such filing (or, if agreed by the parties hereto, such later time and date as may be expressed therein as the effective date and time of the Merger) being the “Effective Time”). Upon the terms and subject to the conditions of this Agreement, at the Effective Time, Merger Sub shall merge with and into NAP, the separate existence of Merger Sub shall cease, and NAP shall continue as the surviving limited partnership in the Merger (the “Surviving Entity”).

(ii) On the Closing Date, concurrently with or as soon as practicable following the Closing (but in any event prior to the filing of the Certificate of Merger), Parent shall cause a certificate of designation, preferences and rights of Parent Series E Preferred Stock, substantially in the form attached hereto as Exhibit A (completed as contemplated by the footnotes thereto) (the “Certificate of Designation”), to be filed with the Office of the Registrar of Corporations of the Republic of the Marshall Islands, duly executed in accordance with the relevant provisions of the Marshall Islands Business Corporations Act. Parent shall cause such filing to become effective upon filing. Notwithstanding the foregoing, in the event that the Common Stock Election Threshold is met, Parent shall not be required to file the Certificate of Designation with the Office of the Registrar of Corporations of the Republic of the Marshall Islands.

(c) Effect of the Merger on Equity Securities. Subject in each case to Sections 2.1(d), 2.1(e) and 2.3, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, NAP, NAP General Partner, any Holder of NAP Common Units, any Holder of Parent Common Stock or Parent Preferred Stock, or any other Person:

(i) Conversion of NAP Public Units. Each of the NAP Public Units outstanding immediately prior to the Effective Time shall be converted into the right to receive the following (as applicable, the “Merger Consideration”):

(A) with respect to 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 validly issued, fully paid and nonassessable Parent Common Stock (or if the Parent Reverse Stock Split is effected prior to the Effective Time, a number of shares of validly issued, fully paid and nonassessable Parent Common Stock equal to the product of 6.292 multiplied by the Reverse Split Ratio) (the “Common Stock Election Consideration”); or

(B) with respect to which an election to receive Parent Series E Preferred Stock as consideration (a “Preferred Stock Election”) is properly made (or deemed to have been made), and not revoked, in accordance with Section 2.3, (x) if the Common Stock Election Threshold is not met, one share of validly issued, fully paid and nonassessable Parent Series E Preferred Stock (the “Preferred Stock Election Consideration”), or (y) if the Common Stock Election Threshold is met, the Common Stock Election Consideration.

12

(ii) Each NAP Public Unit, upon being converted into the right to receive the Merger Consideration pursuant to this Section 2.1(c), shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and each Holder of such NAP Public Unit immediately prior to the Effective Time shall 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 NAP Public Units represented by book-entry (“Book-Entry NAP Common Units”), together with such properly completed and duly executed Letter of Transmittal and such other documents in accordance with 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.

(f) Certain Adjustments. If between the Execution Date and the Effective Time, whether or not permitted pursuant to the terms of this 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.

SECTION 2.2 Exchange of NAP Public Units.

(a) Exchange Agent. Prior to the mailing of the NAP Information Statement, Parent shall appoint a bank, trust company or similar Person to act as exchange agent (the “Exchange Agent”) and establish an exchange fund (the “Exchange Fund”) for the payment of the Merger Consideration and any dividends or distributions payable pursuant to Section 2.2(c). At or prior to the Closing, Parent shall (i) reserve with the Exchange Agent the shares of Parent Issued Stock to be issued pursuant to Section 2.1(c)(i), and (ii) authorize the Exchange Agent to exchange shares of Parent Issued Stock in accordance with this Section 2.2. Parent shall deposit with the Exchange Agent any additional cash as and when necessary to pay any dividends or distributions payable pursuant to Section 2.2(c) and 2.2(d) and other amounts required to be paid under this Agreement. Parent shall pay all costs and fees of the Exchange Agent and all expenses associated with the exchange process. Any shares of Parent Issued Stock, and any other funds deposited with the Exchange Agent shall be returned to Parent after the earlier to occur of (x) payment in full of all amounts due to the Holders of NAP Public Units and (y) the expiration of the period specified in Section 2.2(e).

14

(b) Exchange Procedures. Promptly after the Effective Time, Parent shall, or shall cause the Exchange Agent to, mail to each Holder of NAP Public Units as of the Effective Time whose NAP Public Units were converted into the right to receive the Merger Consideration a form of letter of transmittal (the “Letter of 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

(g) Withholding Rights. Parent, Merger Sub, NAP, the Surviving Entity and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement, without duplication, such amounts, which may include shares of Parent Issued Stock, as Parent, Merger Sub, NAP, the Surviving Entity or the Exchange Agent reasonably deems to be required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or non-U.S. Tax Law. 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.

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.

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 5.4 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.

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.

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.

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.

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.

46

SECTION 7.3 Termination by NAP. This Agreement may be 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).

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.

(c) Each party acknowledges that the agreements contained in this Section 7.6 are an integral part of the 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 remedies will not be the exclusive remedies for any breach of this Agreement but will be in addition to all other remedies available at law or equity to each of the parties.

SECTION 7.9 No Waiver Relating to Claims for Fraud/Willful Misconduct. The liability of any party under this Article VII shall be in addition to, and not exclusive of, any other liability that such party may have at law or in equity based on such party’s (a) fraudulent acts or omissions or (b) willful misconduct. None of the provisions set forth in this Agreement shall be deemed to be a waiver by or release of any party of any right or remedy that such party may have at law or equity based on any other party’s fraudulent acts or omissions or willful misconduct nor shall any such provisions limit, or be deemed to limit, (i) the amounts of recovery sought or awarded in any such claim for fraud or willful misconduct, (ii) the time period during which a claim for fraud or willful misconduct may be brought, or (iii) the recourse that any such party may seek against another party with respect to a claim for fraud or willful misconduct.
