ARTICLE II

REGISTRATION RIGHTS

2.1Registration. Upon receipt of a Notice from NMD, the Partnership shall prepare and file as promptly as reasonably practicable a registration statement under the Securities Act providing for the resale of the Registrable Securities (the “Registration Statement”), which may be a Registration Statement that provides for the resale of the Registrable Securities then outstanding from time to time as permitted by Rule 415 of the Securities Act. The Partnership shall use its commercially reasonable efforts to cause the Registration Statement to become effective on or as soon as reasonably practicable after filing. Any Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holders of any and all Registrable Securities covered by such Registration Statement. The Partnership shall use its commercially reasonable efforts to cause the Registration Statement filed pursuant to thisSection 2.1 to be effective, supplemented and amended to the extent necessary to ensure that it is available at all times for the resale of all Registrable Securities by the Holders until the earlier of (i) the date on which all Registrable Securities covered by the Registration Statement have been sold by the Holder or (ii) six months following such Registration Statement’s effective date (the “Effectiveness Period”).

2.2Piggyback Rights.If the Partnership shall propose to file a Registration Statement (other than pursuant to a demand made pursuant toSection 2.1, a registration effected solely to implement an employee benefit plan or a Registration Statement on Form S-4, S-8 or any successor form thereto or another form not available for registering the Registrable Securities for sale to the public) for a primary Underwritten Offering, then as soon as practicable following the engagement of counsel by the Partnership to prepare the documents to be used in connection with such offering, the Partnership shall give notice (including, notification by electronic mail) of such proposed Underwritten Offering to each Holder (together with its Affiliates) and such notice shall offer such Holder the opportunity to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as each such Holder may request in writing;provided,however, that the number of Included Registrable Securities shall at least equal $30.0 million of Registrable Securities;provided,further, that the Partnership shall not be required to include the Registrable Securities of the Holders in any registration statement prior to the expiration of the lock-up restrictions set forth inArticle IV of the Unitholder Agreement; andprovided,further, that if the Partnership has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will have an adverse effect on the price, timing or distribution of the Units in the Underwritten Offering, then (a) if no Registrable Securities can be included in the Underwritten Offering in the opinion of the Managing Underwriter, the Partnership shall not be required to offer such opportunity to the Holders or (b) if any Registrable Securities can be included in the Underwritten Offering in the opinion of the Managing Underwriter, then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions ofSection 2.3. Any notice required to be provided in thisSection 2.2 to Holders shall be provided on a Business Day pursuant toSection 3.5 hereof and receipt of such

2

notice shall be confirmed by the Holders. Each such Holder shall then have two Business Days (or one Business Day in connection with any overnight or bought Underwritten Offering) after notice has been delivered to request in writing the inclusion of Registrable Securities in the Underwritten Offering. If no written request for inclusion from a Holder is received within the specified time, each such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, the Partnership shall determine for any reason not to undertake or to delay such Underwritten Offering, the Partnership may, at its election, give written notice of such determination to the Selling Holders and, (i) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (ii) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such Underwritten Offering by giving written notice to the Partnership of such withdrawal at or prior to the time of pricing of such Underwritten Offering.

2.3Priority. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering advises the Partnership that the total amount of Registrable Securities that the Selling Holders and any other Persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Units offered or the market for the Units, then the Units to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advises the Partnership can be sold without having such adverse effect, with such number to be allocated (i) first, to the Partnership and (ii) second, pro rata among the Selling Holders who have requested participation in such Underwritten Offering and any other holder of securities of the Partnership having rights of registration that are neither expressly senior nor subordinated to the Registrable Securities (the “Parity Securities”). The pro rata allocations for each Selling Holder who has requested participation in such Underwritten Offering shall be the product of (i) the aggregate number of Registrable Securities proposed to be sold in such Underwritten Offering multiplied by (ii) the fraction derived by dividing (x) the number of Registrable Securities owned on the Execution Date by such Selling Holder by (y) the aggregate number of Registrable Securities owned on the Execution Date by the Selling Holders plus the aggregate number of Parity Securities owned on the Execution Date by all holders of Parity Securities that are participating in the Underwritten Offering.

2.4Delay Rights. Notwithstanding anything to the contrary contained herein, if Marlin GP determines that the Partnership’s compliance with its obligations in thisArticle II would be detrimental to the Partnership because such registration would (a) materially interfere with a significant acquisition, reorganization or other similar transaction involving the Partnership, (b) require premature disclosure of material information that the Partnership has a bona fide purpose for preserving as confidential, (c) render the Partnership unable to comply with requirements under applicable securities Laws, or (d) have a material adverse effect on the Partnership, then the Partnership may postpone compliance with such obligations for a period of not more than six months, provided, however, that such right may not be exercised more than twice in any 24-month period.

3

2.5Underwritten Offerings.

(a)Request for a Secondary Offering. If NMD elects to dispose of a number of Registrable Securities that NMD reasonably anticipates will result in gross proceeds of at least $30 million in the aggregate, the Partnership shall, upon Notice by NMD, retain underwriters that are reasonably acceptable to NMD in order to permit for NMD to effect such sale through an Underwritten Offering (a “Secondary Offering”).

(b)Limitation on Offerings. NMD may exercise its right to demand a Secondary Offering of its Registrable Securities no more than two times in any twelve-month period and no more than six times pursuant to this Agreement.

(c)General Procedures. In connection with any Underwritten Offering under this Agreement, the Partnership shall be entitled to select the Managing Underwriter or Underwriters. In connection with an Underwritten Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder and the Partnership shall enter into an underwriting agreement that contains such representations, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of securities and that are reasonably acceptable to the Partnership. No Holder may participate in such Underwritten Offering unless such Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. If any Selling Holder disapproves of the terms or conditions of an underwriting agreement, such Selling Holder may elect to withdraw therefrom by notice to the Partnership and the Managing Underwriter;provided,however, that such withdrawal must be made up to and including the time of pricing of such Underwritten Offering. No such withdrawal or abandonment shall affect the Partnership’s obligation to pay Registration Expenses. The Partnership’s management may but shall not be required to participate in a roadshow or similar marketing effort in connection with any Underwritten Offering.

2.6Sale Procedures. In connection with its obligations under thisArticle II, the Partnership will:

(a) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing the Registration Statement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Registration Statement or supplement or amendment thereto, and (ii) such number of copies of the Registration Statement and the prospectus included therein and any supplements and amendments thereto as such Selling Holder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration Statement,provided,however, that the Partnership will not have any obligation to provide any document pursuant toclause (ii) immediately above that is available on the Commission’s website;

4

(b) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Registration Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the Managing Underwriter, shall reasonably request; provided, however, that the Partnership will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject;

(c) promptly notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered by any of them under the Securities Act, of (i) the filing of the Registration Statement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or anypost-effective amendment thereto, when the same has become effective; and (ii) the receipt of any written comments from the Commission with respect to any filing referred to inclause (i) immediately above and any written request by the Commission for amendments or supplements to the Registration Statement or any prospectus or prospectus supplement thereto;

(d) immediately notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained therein, in the light of the circumstances under which a statement is made); (ii) the issuance or express threat of issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, or the initiation of any proceedings for that purpose; or (iii) the receipt by the Partnership of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, the Partnership agrees to, as promptly as practicable, amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(e) enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of such Registrable Securities, including the provision of comfort letters and legal opinions as are customary in such securities offerings; and

5

2.7Suspension.Each Selling Holder, upon receipt of notice from the Partnership of the happening of any event of the kind described inSection 2.6(d), shall forthwith discontinue disposition of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by such subsection or until it is advised in writing by the Partnership that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus.

2.8Cooperation by Holders. The Partnership shall have no obligation to include Registrable Securities of a Holder in the Registration Statement or in an Underwritten Offering pursuant toSection 2.2 who has failed to timely furnish such information regarding such Holder and its ownership of the Registrable Securities being offered and its intended method of distribution that the Partnership determines, after consultation with its counsel, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act or to verify the rights of the Holder hereunder.

2.9Restrictions on Public Sale by Holders of Registrable Securities. So long as NMD continues to hold Registrable Securities, each Holder agrees that in connection with any public offering of by the Partnership and upon the request of the Managing Underwriting, such Holder shall not, without the prior written consent of such Managing Underwriter, during the period commencing on the effective date of such registration and ending on the date specified by such Managing Underwriter (such period not to exceed 90 days): (a) offer, pledge, sell, contract to sell, grant any option or contract to purchase, purchase any option or contract to sell, hedge the beneficial ownership of or otherwise dispose of, directly or indirectly, any Registrable Securities; (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of Units or such other securities, in cash or otherwise. The foregoing provisions of thisSection 2.9 shall not apply to sales of Registrable Securities to be included in such offering pursuant toSection 2.1 andSection 2.2 and the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the Partnership or the officers, directors or any other Affiliate of the Partnership on whom a restriction is imposed.

2.10Expenses. Except as set forth in an underwriting agreement for the applicable Underwritten Offering or as otherwise agreed between the Selling Holders and the Partnership, the Partnership shall pay all reasonable Registration Expenses as determined in good faith, including, in the case of an Underwritten Offering, whether or not any sale is made pursuant to such Underwritten Offering. Each Selling Holder shall pay all Selling Expenses that are allocable to such Selling Holder’s pro rata share of Registrable Securities offered hereunder. In addition, except as otherwise provided inSection 2.11 hereof, the Partnership shall not be responsible for legal fees and expenses of counsel and advisors to the Selling Holders or incurred by the Holders in connection with the exercise of such Holders’ rights hereunder.

2.11Indemnification.

(a)By the Partnership. In addition to, and not in limitation of, the Partnership’s obligations under Section 7.7 of the Partnership Agreement, in the event of the

6

filing of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, the Partnership will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, employees and agents and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, and its directors, officers, employees or agents (collectively, the “Selling Holder Indemnified Persons”), against any and all losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses), judgments, fines, penalties, interest settlements or other amounts (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of, are based upon or result from any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in the Registration Statement, any preliminary prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of are based upon or result from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings;provided,however, that the Partnership will not be liable to any Selling Holder Indemnified Person in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in reliance upon and in conformity with information furnished by such Selling Holder Indemnified Person in writing to the Partnership specifically for use in a Registration Statement, any preliminary prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereof.

(b)By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless the Partnership, Marlin GP, its directors, officers, employees and agents and each Person, if any, who controls the Partnership within the meaning of the Securities Act or the Exchange Act, and its directors, officers, employees and agents, to the same extent as the foregoing indemnity from the Partnership to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in a Registration Statement, any preliminary prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereof.

(c)Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party other than under thisSection 2.11. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such

7

indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under thisSection 2.11 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected;provided,however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnified party.

(d)Contribution. If the indemnification provided for in thisSection 2.11 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of the indemnifying party on the one hand and the indemnified party on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Parties agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss that is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e)Other Indemnification. The provisions of thisSection 2.11 shall be in addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise.

8

2.12Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, the Partnership agrees to use its commercially reasonable efforts to:

(a) make and keep public information regarding the Partnership available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof;

(b) file with the Commission in a timely manner all reports and other documents required of the Partnership under the Securities Act and the Exchange Act at all times from and after the date hereof; and

(c) so long as a Holder owns any Registrable Securities, furnish, unless otherwise available via EDGAR, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Partnership, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

2.13Termination of Registration Rights under the Partnership Agreement. Notwithstanding anything set forth in this Agreement to the contrary, any and all registration rights of NMD or its Affiliates or their respective transferees with respect to the subject matter of this Agreement as provided for in the Partnership Agreement, or any predecessor agreement, are hereby terminated and no longer any force or effect.

ARTICLE III

OTHER PROVISIONS

3.2Consent to Jurisdiction.

Each of the Parties also agrees that any final and non-appealable judgment against a Party in connection with

9

any Proceeding shall be conclusive and binding on such Party and that such award or judgment may be enforced in any court of competent jurisdiction, either within or outside of the United States.
