Voting Securities

        Stockholders of NMFC may vote their shares, in person or by proxy, at the Annual Meeting only if such stockholders were stockholders of record at the close of business on March 11, 2014 (the "Record Date"). On the Record Date, there were 47,896,693 shares of the NMFC's common stock outstanding. Each share of NMFC's common stock is entitled to one vote.

        Unit holders of NMF Holdings may vote their units in person or by proxy, at the Annual Meeting only if such unit holders were unit holders of record on the Record Date. On the Record Date, there were 47,896,693 units of NMF Holdings outstanding. Each unit of NMF Holdings is entitled to one vote.

        NMFC is a holding company with no direct operations of its own, and its only business and sole asset is its ownership of units of NMF Holdings. As of the Record Date, NMFC owned 100.0% of the outstanding units of NMF Holdings. Stockholders of NMFC will vote on matters relating to NMF Holdings on a pass-through basis.

        Stockholders of NMFC may vote their proportionate share of NMF Holdings' units held by NMFC on a pass-through basis, in person or by proxy, at the Annual Meeting only if such stockholders were stockholders of record on the Record Date. Each share of NMFC's common stock entitles the holder to vote one unit of NMF Holdings.

The presence at the Annual Meeting, in person or by proxy, of (i) the holders of a majority of the shares of NMFC common stock outstanding on the Record Date will constitute a quorum. Abstentions will be treated as Voting Securities present for quorum purposes. Broker Securities for which the nominee has not received voting instructions from the record holder and does not have discretionary authority to vote the Voting Securities on certain proposals (which are considered "Broker Non-Votes" with respect to such proposals) will be treated as Voting Securities present for quorum purposes.

The persons named as proxies will vote those proxies for such adjournment, unless marked to be voted against any proposal for which an adjournment is sought, to permit the further solicitation of proxies.

Vote Required

        Election of Directors.    A nominee for director shall be elected to the board of directors of each New Mountain Finance Entity if the votes cast for such nominee's election exceed the votes cast against such nominee's election. If you vote "Withhold Authority" with respect to a nominee, your shares will not be voted with respect to the person indicated. Abstentions and Broker Non-Votes will not be included in determining the number of votes cast and, as a result, will have no effect on this proposal.

Abstentions and Broker Non-Votes will have the effect of a vote against this proposal.

Abstentions and Broker Non-Votes will have the effect of a vote against this proposal.

        Additional Solicitation.    If there are not enough votes to approve any proposals at the Annual Meeting, the stockholders and unit holders who are represented may adjourn the Annual Meeting to permit the further solicitation of proxies. The persons named as proxies will vote those proxies for such adjournment, unless marked to be voted against the proposal for which an adjournment is sought, to permit the further solicitation of proxies.

        Also, a vote may be taken on one or more of the proposals in this Joint Proxy Statement prior to any such adjournment if there are sufficient votes for approval thereof.

Information Regarding This Solicitation

We have requested that brokers, nominees, fiduciaries and other persons holding Voting Securities in their names, or in the name of their nominees, which are beneficially owned by others, forward the proxy materials to, and obtain proxies from, such beneficial owners. We will reimburse such persons for their reasonable expenses in so doing.

compensation therefor. The New Mountain Finance Entities have also retained AST Fund Solutions LLC to assist in the solicitation of proxies for the annual meeting for a fee of approximately $26,000, plus reimbursement of certain out of pocket expenses.

        Holders of Voting Securities may also provide their voting instructions by telephone or through the internet. These options require holders of Voting Securities to input the Control Number which is located on each proxy card.

Information about Executive Officers Who Are Not Directors

        The following information, as of the Record Date, pertains to the executive officers who are not directors or nominees for election as directors of the New Mountain Finance Entities.

Director Independence

        In accordance with rules of the NYSE, the New Mountain Finance Entities' boards of directors annually determine each director's independence. We do not consider a director independent unless the boards of directors have determined that he has no material relationship with us. We monitor the relationships of our directors and officers through a questionnaire each director completes no less frequently than annually and updates periodically as information provided in the most recent questionnaire changes.

12

---

        Our governance guidelines, which are available on the New Mountain Finance Entities' website at http://www.newmountainfinance.com, require any director who has previously been determined to be independent to inform the chairman of the boards of directors, the chairman of the nominating and corporate governance committees and the corporate secretary of any change in circumstance that may cause his status as an independent director to change. The boards of directors limit membership on the audit committees, the valuation committees, the nominating and corporate governance committees and the compensation committees to independent directors. In order to evaluate the materiality of any such relationship, the boards of directors use the definition of director independence set forth in the corporate governance listing standards promulgated by the NYSE.

        The boards of directors have determined that each of the directors and the director nominees are independent and has no relationship with us, except as a director and stockholder of NMFC, with the exception of Steven B. Klinsky, as a result of his positions as founder and chief executive officer of New Mountain Capital, L.L.C., Robert A. Hamwee, as a result of his positions as chief executive officer and president of the New Mountain Finance Entities and Adam B. Weinstein, as a result of his positions as executive vice president and chief administrative officer of the New Mountain Finance Entities.

Board Leadership Structure

        The New Mountain Finance Entities' boards of directors monitor and perform an oversight role with respect to the New Mountain Finance Entities' businesses and affairs, compliance with regulatory requirements and the services, expenses and performance of service providers to the New Mountain Finance Entities. Among other things, the New Mountain Finance Entities' boards of directors approve the appointment of the Administrator and officers, review and monitor the services and activities performed by the Administrator and officers and approve the engagement, and review the performance of, the New Mountain Finance Entities' independent public accounting firm.

        Under the New Mountain Finance Entities' bylaws, the New Mountain Finance Entities' boards of directors may designate a chairman to preside over the meetings of the boards of directors and meetings of the stockholders/unit holder and to perform such other duties as may be assigned to him by the boards of directors. The New Mountain Finance Entities do not have a fixed policy as to whether the chairman of the boards should be an independent director and believe that they should maintain the flexibility to select the chairman and reorganize the leadership structure, from time to time, based on the criteria that is in the best interests of the New Mountain Finance Entities and their stockholders/unit holder at such times.

        Mr. Klinsky currently serves as the chairman of the New Mountain Finance Entities' boards of directors. Mr. Klinsky is an "interested person" of the New Mountain Finance Entities as defined in Section 2(a)(19) of the 1940 Act because he is the founder and chief executive officer of New Mountain Capital, L.L.C., serves on the investment committee of the Investment Adviser and is the managing member of the sole member of the Investment Adviser. The New Mountain Finance Entities believe that Mr. Klinsky's history with New Mountain Capital, L.L.C., familiarity with our investment objectives and investment strategy, and extensive knowledge of the financial services industry and the investment valuation process in particular qualify him to serve as the chairman of the New Mountain Finance Entities' boards of directors. The New Mountain Finance Entities believe that, at present, they are best served through this leadership structure, as Mr. Klinsky's relationship with the Investment Adviser and New Mountain Capital, L.L.C., provides an effective bridge and encourages an open dialogue between the New Mountain Finance Entities' management and their boards of directors, ensuring that all groups act with a common purpose.

        The New Mountain Finance Entities' boards of directors do not currently have a designated lead independent director. The New Mountain Finance Entities are aware of the potential conflicts that may

13

---

arise when a non-independent director is chairman of the boards of directors, but believe these potential conflicts are offset by their strong corporate governance policies. The New Mountain Finance Entities' corporate governance policies include regular meetings of the independent directors in executive session without the presence of interested directors and management over which the Chairman of the Audit Committee presides, the establishment of audit and nominating and corporate governance committees comprised solely of independent directors and the appointment of a chief compliance officer, with whom the independent directors meet regularly without the presence of interested directors and other members of management, for administering the New Mountain Finance Entities' compliance policies and procedures.

        The New Mountain Finance Entities recognize that different board leadership structures are appropriate for companies in different situations. The New Mountain Finance Entities intend to re-examine their corporate governance policies on an ongoing basis to ensure that they continue to meet their needs.

Boards of Directors' Role In Risk Oversight

        The New Mountain Finance Entities' boards of directors perform their risk oversight function primarily through (1) their four standing committees which report to the boards of directors, each of which are comprised solely of independent directors and (2) active monitoring by the New Mountain Finance Entities' chief compliance officer and their compliance policies and procedures. In addition, the New Mountain Finance Entities' boards of directors rely on the risk oversight function of NMF Holdings' board of directors.

        The New Mountain Finance Entities' audit committees and nominating and corporate governance committees assist their boards of directors in fulfilling their risk oversight responsibilities. The audit committees' risk oversight responsibilities include overseeing the New Mountain Finance Entities' accounting and financial reporting processes, their systems of internal controls regarding finance and accounting, and audits of the New Mountain Entities' financial statements, including the independence of the New Mountain Finance Entities' independent auditors. The nominating and corporate governance committees' risk oversight responsibilities include selecting, researching and nominating directors for election by the New Mountain Finance Entities' stockholders/unit holder, developing and recommending to the boards of directors a set of corporate governance principles and overseeing the evaluation of the boards of directors and the New Mountain Finance Entities' management. The valuation committees are responsible for making recommendations in accordance with the valuation policies and procedures adopted by the boards of directors of the New Mountain Finance Entities, reviewing valuations and any reports of independent valuation firms, confirming that valuations are made in accordance with the valuation policies of the boards of directors of the New Mountain Finance Entities, reporting any deficiencies or violations of such valuation policies to the boards of directors on at least a quarterly basis and reviewing other matters that the boards of directors or the valuation committees deem appropriate.

        The New Mountain Finance Entities' boards of directors perform their risk oversight responsibilities with the assistance of the chief compliance officer. The boards of directors quarterly review a written report from the chief compliance officer discussing the adequacy and effectiveness of the New Mountain Finance Entities' compliance policies and procedures and their service providers. The chief compliance officer's quarterly report addresses at a minimum:

•

the operation of the New Mountain Finance Entities' compliance policies and procedures and their service providers since the last report;



•

any material changes to these policies and procedures since the last report;

14

---

•

any recommendations for material changes to these policies and procedures as a result of the chief compliance officer's annual review; and



•

any compliance matter that has occurred since the date of the last report about which the boards of directors would reasonably need to know to oversee the New Mountain Finance Entities' compliance activities and risks.

        In addition, the chief compliance officer meets separately in executive session with the independent directors at least once each year.

        The New Mountain Finance Entities believe that their boards of directors' role in risk oversight is effective, and appropriate given the extensive regulation to which they are subject as business development companies. The New Mountain Finance Entities are required to comply with certain regulatory requirements that control the levels of risk in the New Mountain Finance Entities' businesses and operations. Since NMFC has no assets other than its ownership of units of NMF Holdings and has no material long-term liabilities, NMFC looks to the assets of NMF Holdings for purposes of satisfying these requirements. For example, the NMF Holdings' ability to incur indebtedness is limited because its asset coverage must equal at least 200.0% immediately after it incurs indebtedness, NMF Holdings generally has to invest at least 70.0% of its total assets in "qualifying assets" and is not generally permitted to invest in any portfolio company in which one of its affiliates currently has an investment.

        The New Mountain Finance Entities recognize that different boards of director roles in risk oversight are appropriate for companies in different situations. The New Mountain Finance Entities intend to re-examine the manners in which the boards of directors administer their oversight function on an ongoing basis to ensure that they continue to meet the New Mountain Finance Entities' needs.

Committees of the Boards of Directors

        The New Mountain Finance Entities' boards of directors have each established an audit committee, a nominating and corporate governance committee and a valuation committee. Additionally, the board of directors of NMFC has established a compensation committee. The members of each committee have been appointed by the respective board or boards of directors of the New Mountain Finance Entities and serve until their successor is elected and qualifies, unless they are removed or resign. During 2013, the boards of directors of the New Mountain Finance Entities held eight board of directors meetings, five audit committee meetings, three nominating and corporate governance committee meetings and eight valuation committee meetings. The compensation committee of NMFC held two meetings during 2013. All directors attended at least 75.0% of the aggregate number of meetings of the boards of directors and of the respective committees of each of the New Mountain Finance Entities on which they serve. We require each director to make a diligent effort to attend all board and committee meetings as well as each annual meeting of the New Mountain Finance Entities' stockholders/unit holder.

Audit Committees

        The audit committees operate pursuant to charters approved by the New Mountain Finance Entities' boards of directors, copies of which are available on the New Mountain Finance Entities' website at http://www.newmountainfinance.com. The charters set forth the responsibilities of the audit committees. The audit committees are responsible for recommending the selection of, engagement of and discharge of the New Mountain Finance Entities' independent auditors, reviewing the plans, scope and results of the audit engagement with the independent auditors, approving professional services provided by the independent auditors (including compensation therefore), reviewing the independence of the independent auditors and reviewing the adequacy of the New Mountain Finance Entities' internal controls over financial reporting. The members of the audit committees are

---

Alfred F. Hurley, Jr., David Ogens, David R. Malpass and Kurt J. Wolfgruber, each of whom is not an interested person of the New Mountain Finance Entities for purposes of the 1940 Act and is independent for purposes of the NYSE's corporate governance listing standards. Kurt J. Wolfgruber serves as the chairman of the audit committees and the New Mountain Finance Entities' boards of directors have determined that Alfred F. Hurley, Jr., David Ogens and Kurt J. Wolfgruber are "audit committee financial experts" as that term is defined under Item 407 of Regulation S-K, as promulgated under the Exchange Act, and that each of them meets the current independence and experience requirements of Rule 10A-3 of the Exchange Act.

Nominating and Corporate Governance Committees

        The nominating and corporate governance committees operate pursuant to charters approved by the New Mountain Finance Entities' boards of directors, copies of which are available on the New Mountain Finance Entities' website at http://www.newmountainfinance.com. The charters set forth the responsibilities of the nominating and corporate governance committees. The nominating and corporate governance committees are responsible for determining criteria for service on the boards of directors identifying, researching and nominating directors for election by the New Mountain Finance Entities' stockholders/unit holder, selecting nominees to fill vacancies on the New Mountain Finance Entities' boards of directors or committees of the boards of directors, developing and recommending to the boards of directors a set of corporate governance principles and overseeing the self-evaluation of the boards of directors and their committees and evaluation of the New Mountain Finance Entities' management. The nominating and corporate governance committees consider nominees properly recommended by the New Mountain Finance Entities' stockholders/unit holder. The members of the nominating and corporate governance committees are Alfred F. Hurley, Jr., David Ogens, David R. Malpass and Kurt J. Wolfgruber, each of whom is not an interested person of the New Mountain Finance Entities for purposes of the 1940 Act and is independent for purposes of the NYSE's corporate governance listing standards. Alfred F. Hurley, Jr. serves as the chairman of the nominating and corporate governance committees.

        The nominating and corporate governance committees seek candidates who possess the background, skills and expertise to make a significant contribution to the boards of directors, the New Mountain Finance Entities and their stockholders/unit holder. In considering possible candidates for election as a director, the nominating and corporate governance committees take into account, in addition to such other factors as they deem relevant, the desirability of selecting directors who:

•

are of high character and integrity;



•

are accomplished in their respective fields, with superior credentials and recognition;



•

have relevant expertise and experience upon which to be able to offer advice and guidance to management;



•

have sufficient time available to devote to the affairs of the New Mountain Finance Entities;



•

are able to work with the other members of the boards of directors and contribute to the success of the New Mountain Finance Entities;



•

can represent the long-term interests of the New Mountain Finance Entities' stockholders/unit holder as a whole; and



•

are selected such that the boards of directors represent a range of backgrounds and experience.

        The nominating and corporate governance committees have not adopted formal policies with regard to the consideration of diversity in identifying director nominees. In determining whether to recommend a director nominee, the nominating and corporate governance committees consider and discuss diversity, among other factors, with a view toward the needs of the boards of directors as a

16

---

whole. The nominating and corporate governance committees generally conceptualize diversity expansively to include, without limitation, concepts such as race, gender, national origin, differences of viewpoint, professional experience, education, skill and other qualities that contribute to the boards of directors, when identifying and recommending director nominees. The nominating and corporate governance committees believe that the inclusion of diversity as one of many factors considered in selecting director nominees is consistent with the nominating and corporate governance committees' goal of creating boards of directors that best serve the needs of the New Mountain Finance Entities and the interest of their stockholders/unit holder.

Compensation Committees

        The compensation committee operates pursuant to a charter approved by NMFC's board of directors, a copy of which is available on the New Mountain Finance Entities' website at http://www.newmountainfinance.com. The charter sets forth the responsibilities of the compensation committee. The compensation committee is responsible for periodically reviewing director compensation and recommending any appropriate changes to the board of directors. In addition, although NMFC does not directly compensate its executive officers currently, to the extent that it does so in the future, the compensation committee would also be responsible for reviewing and evaluating their compensation and making recommendations to the board of directors regarding their compensation. Lastly, the compensation committee would produce a report on NMFC's executive compensation practices and policies for inclusion in our proxy statement if required by applicable proxy rules and regulations and, if applicable, make recommendations to the board of directors on NMFC's executive compensation practices and policies. The compensation committee has the authority to engage compensation consultants, although it does not currently do so, and to delegate its duties and responsibilities to a member or to a subcommittee of the compensation committee. The compensation committee is composed of Alfred F. Hurley, Jr., David Ogens, David R. Malpass and Kurt J. Wolfgruber, each of whom is not an interested person of NMFC for purposes of the 1940 Act and is independent for purposes of the NYSE's corporate governance listing standards. Alfred F. Hurley, Jr. serves as chairman of the compensation committee.

Valuation Committees

        The valuation committees operate pursuant to charters approved by the New Mountain Finance Entities' boards of directors, copies of which are available on the New Mountain Finance Entities' website at http://www.newmountainfinance.com. The charters set forth the responsibilities of the valuation committees. The valuation committees are responsible for making recommendations in accordance with the valuation policies and procedures adopted by the boards of directors of the New Mountain Finance Entities, reviewing valuations and any reports of independent valuation firms, confirming that valuations are made in accordance with the valuation policies of the boards of directors of the New Mountain Finance Entities and reporting any deficiencies or violations of such valuation policies to the boards of directors on at least a quarterly basis, and reviewing other matters that the boards of directors or the valuation committees deem appropriate. The valuation committees are composed of Alfred F. Hurley, Jr., David Ogens, David R. Malpass and Kurt J. Wolfgruber, each of whom is not an interested person of the New Mountain Finance Entities for purposes of the 1940 Act and is independent for purposes of the NYSE's corporate governance listing standards. David Ogens serves as chairman of the valuation committees.

Compensation of Executive Officers

        None of the New Mountain Finance Entities' executive officers receive direct compensation from the New Mountain Finance Entities. The New Mountain Finance Entities do not engage any compensation consultants. The compensation of the principals and other investment professionals of the Investment Adviser is paid by the Investment Adviser. Compensation paid to the New Mountain Finance Entities' chief financial officer and chief compliance officer is set by the Administrator and is subject to reimbursement by NMF Holdings of the allocable portion of such compensation for services rendered to the New Mountain Finance Entities.

Indemnification Agreements

        NMFC and NMF Holdings have entered into indemnification agreements with their respective directors. The indemnification agreements are intended to provide the directors the maximum indemnification permitted under Delaware law and the 1940 Act. Each indemnification agreement provides that NMFC or NMF Holdings, as applicable, shall indemnify the director who is a party to the agreement, or an Indemnitee, including the advancement of legal expenses, if, by reason of his corporate status, the Indemnitee is, or is threatened to be, made a party to or a witness in any threatened, pending, or completed proceeding, to the maximum extent permitted by Delaware law and the 1940 Act. Any amounts owing by NMFC to any Indemnitee pursuant to the indemnification agreements will be payable by NMF Holdings.

Certain Relationships and Transactions

        As of the Record Date, NMFC owns all the outstanding units of NMF Holdings.

        NMF Holdings has entered into an Investment Advisory and Management Agreement with the Investment Adviser. Pursuant to the Investment Advisory and Management Agreement, payments will be equal to (a) a base management fee of 1.75% of the value of NMF Holdings' gross assets and (b) an incentive fee based on NMF Holdings' performance. Steven B. Klinsky, through his financial interest in the Investment Adviser, is entitled to a portion of any profits earned by the Investment Adviser, which includes any fees payable to the Investment Adviser under the terms of the Investment Advisory and Management Agreement, less expenses incurred by the Investment Adviser in performing its services under the Investment Advisory and Management Agreement. In addition, the New Mountain Finance Entities' executive officers and directors, as well as the current or future members of the Investment Adviser, serve or may serve as officers, directors or principals of entities that operate in the same or a related line of business as the New Mountain Finance Entities do or of investment funds managed by the New Mountain Finance Entities' affiliates. Accordingly, they may have obligations to investors in those entities, the fulfillment of which might not be in the best interests of NMF Holdings, NMFC or NMFC's stockholders.

        Although NMF Holdings is currently New Mountain Capital, L.L.C.'s only vehicle focused primarily on investing in first and second lien debt, unsecured notes and mezzanine securities, in the future, the principals of the Investment Adviser and/or New Mountain Capital, L.L.C. employees that provide services pursuant to the Investment Advisory and Management Agreement may manage other funds which may from time to time have overlapping investment objectives with NMF Holdings' and, accordingly, may invest in, whether principally or secondarily, asset classes similar to those targeted by NMF Holdings. If this occurs, the Investment Adviser may face conflicts of interest in allocating investment opportunities to NMF Holdings and such other funds. Although the investment professionals will endeavor to allocate investment opportunities in a fair and equitable manner, it is possible that NMF Holdings may not be given the opportunity to participate in certain investments made by investment funds managed by the Investment Adviser or persons affiliated with the Investment Adviser or that certain of these investment funds may be favored over NMF Holdings. When these

19

---

Table of Contents

investment professionals identify an investment, they will be forced to choose which investment fund should make the investment. Alternatively, depending on the availability of such investment and other appropriate factors, the Investment Adviser or its affiliates may determine that NMF Holdings should invest side-by-side with one or more other funds. Any such investments will be made only to the extent permitted by applicable law and interpretive positions of the SEC and its staff, and consistent with the Investment Adviser's allocation procedures.

        The New Mountain Finance Entities have entered into an Administration Agreement, with the Administrator, a wholly-owned subsidiary of New Mountain Capital. The Administrator arranges office space for the New Mountain Finance Entities and provides office equipment and administrative services necessary to conduct their respective day-to-day operations pursuant to the Administration Agreement. NMF Holdings reimburses the Administrator for the allocable portion of overhead and other expenses incurred by it in performing its obligations to the New Mountain Finance Entities under the Administration Agreement, including rent, the fees and expenses associated with performing administrative, finance, and compliance functions, and the compensation of NMF Holdings, chief financial officer and chief compliance officer and their respective staffs. Pursuant to the Administration Agreement and further restricted by NMF Holdings, expenses payable to the Administrator by NMF Holdings as well as other direct and indirect expenses (excluding interest, other credit facility expense, trading expenses and management and incentive fees) has been capped at $3.5 million for the time period from April 1, 2012 to March 31, 2013 and capped at $4.25 million for the time period from April 1, 2013 to March 31, 2014. The expense cap will expire on March 31, 2014. Thereafter, the Administrator may, in its own discretion, submit to NMF Holdings for reimbursement some or all of the expenses that the Administrator has incurred on behalf of NMF Holdings during any quarterly period. As a result, the amount of expenses for which NMF Holdings will have to reimburse the Administrator may fluctuate in future quarterly periods and there can be no assurance given as to when, or if, the Administrator may determine to limit the expenses that the Administrator submits to NMF Holdings for reimbursement in the future. However, it is expected that the Administrator will continue to support part of the expense burden of NMF Holdings in the near future.

        The New Mountain Finance Entities, the Investment Adviser and the Administrator, have also entered into a Trademark License Agreement, as amended, with New Mountain Capital, L.L.C., pursuant to which New Mountain Capital, L.L.C. has agreed to grant each of the New Mountain Finance Entities, the Investment Adviser and the Administrator, a non-exclusive, royalty-free license to use the New Mountain and the New Mountain Finance names. Under the Trademark License Agreement, as amended, subject to certain conditions, NMFC, NMF Holdings, the Investment Adviser and the Administrator, will have a right to use the New Mountain and the New Mountain Finance names, for so long as the Investment Adviser or one of its affiliates remains the investment adviser of NMF Holdings. Other than with respect to this limited license, NMFC, NMF Holdings, the Investment Adviser and the Administrator, will have no legal right to the New Mountain and the New Mountain Finance names.

        NMFC has entered into a joinder agreement with respect to the Amended and Restated Limited Liability Company Agreement, as amended, of NMF Holdings pursuant to which NMFC was admitted as a member of the NMF Holdings. Concurrently with the closing of NMFC's initial public offering, NMFC sold 2,172,000 shares of its common stock to certain executives and employees of, and other individuals affiliated with, New Mountain Capital, L.L.C. in a separate private placement at the initial public offering price per share.

        NMFC entered into a Registration Rights Agreement with New Mountain Finance AIV Holdings Corporation ("AIV Holdings"), Steven B. Klinsky (the chairman of our boards of directors), an entity related to Steven B. Klinsky and the Investment Adviser. Subject to several exceptions, AIV Holdings and the Investment Adviser have the right to require NMFC to register for public resale under the Securities Act of 1933, as amended, all registerable securities that are held by any of them and that

they request to be registered. Registerable securities subject to the Registration Rights Agreement are shares of NMFC's common stock issued or issuable in exchange for units and any other shares of NMFC's common stock held by AIV Holdings, the Investment Adviser and any of their transferees. The rights under the Registration Rights Agreement can be conditionally exercised by AIV Holdings or the Investment Adviser, meaning that prior to the effectiveness of the registration statement related to the shares, AIV Holdings or the Investment Adviser can withdraw their request to have the shares registered. AIV Holdings and the Investment Adviser may each assign their rights to any person that acquires registerable securities subject to the Registration Rights Agreement and who agrees to be bound by the terms of the Registration Rights Agreement. Steven B. Klinsky and a related entity will have the right to "piggyback", or include their own registrable securities in such a registration. Shares held by AIV Holdings and Steven B. Klinsky were registered on a shelf registration statement on Form N-2.

        Holders of registerable securities have "piggyback" registration rights, including AIV Holdings, which means that these holders may include their respective shares in any future registrations of NMFC's equity securities, whether or not that registration relates to a primary offering by NMFC or a secondary offering by or on behalf of any of NMFC's stockholders. AIV Holdings, the Investment Adviser and Steven B. Klinsky (and a related entity) have priority over NMFC in any registration that is an underwritten offering.

        AIV Holdings, the Investment Adviser and Steven B. Klinsky (and a related entity) will be responsible for the expenses of any demand registration (including underwriters' discounts or commissions) and their pro-rata share of any "piggyback" registration. NMFC has agreed to indemnify AIV Holdings, the Investment Adviser and Steven B. Klinsky (and a related entity) with respect to liabilities resulting from untrue statements or omissions in any registration statement filed pursuant to the Registration Rights Agreement, other than untrue statements or omissions resulting from information furnished to NMFC by such parties. AIV Holdings, the Investment Adviser and Steven B. Klinsky (and a related entity) have also agreed to indemnify NFMC with respect to liabilities resulting from untrue statements or omissions furnished by them to NMFC relating to them in any registration statement.

        In the ordinary course of business, NMF Holdings may enter into transactions with portfolio companies that may be considered related party transactions. In order to ensure that NMF Holdings does not engage in any prohibited transactions with any persons affiliated with NMF Holdings, NMF Holdings has implemented certain policies and procedures whereby its executive officers screen each of its transactions for any possible affiliations between the proposed portfolio investment, NMF Holdings, companies controlled by NMF Holdings and its employees and directors. NMF Holdings will not enter into any agreements unless and until it is satisfied that doing so will not raise concerns under the 1940 Act or, if such concerns exist, NMF Holdings has taken appropriate actions to seek board review and approval or exemptive relief for such transaction. NMF Holdings' board of directors reviews these procedures on a quarterly basis.

        The New Mountain Finance Entities have each adopted a Code of Ethics which applies to, among others, their senior officers, including their respective chief executive officer and chief financial officer, as well as all of their officers, directors and employees. The New Mountain Finance Entities' Codes of Ethics require that all employees and directors avoid any conflict, or the appearance of a conflict, between an individual's personal interests and the New Mountain Finance Entities' interests.

Board Consideration of the Investment Advisory and Management Agreement

        NMF Holdings' board of directors determined at an in-person meeting held on February 4, 2014, to approve the Amended and Restated Investment Advisory and Management Agreement between NMF Holdings and the Investment Adviser. In its consideration of the approval of the Amended and Restated Investment Advisory and Management Agreement, the board of directors of NMF Holdings focused on information it had received relating to, among other things:

•

the nature, quality and extent of the advisory and other services to be provided to NMF Holdings by the Investment Adviser;



•

comparative data with respect to advisory fees or similar expenses paid by other business development companies with similar investment objectives;



•

NMF Holdings' projected operating expenses and expense ratio compared to business development companies with similar investment objectives;



•

any existing and potential sources of indirect income to the Investment Adviser or the Administrator from their relationships with NMF Holdings and the profitability of those relationships, including through the Amended and Restated Investment Advisory and Management Agreement and the Administration Agreement;



•

information about the services to be performed and the personnel performing such services under the Amended and Restated Investment Advisory and Management Agreement;



•

the organizational capability and financial condition of the Investment Adviser and its affiliates;



•

the Investment Adviser's practices regarding the selection and compensation of brokers that may execute NMF Holdings' portfolio transactions and the brokers' provision of brokerage and research services to the Investment Adviser; and



•

the possibility of obtaining similar services from other third party service providers or through an internally managed structure.

        Based on the information reviewed and the discussions, the board of directors of NMF Holdings, including a majority of the non-interested directors, concluded that fees payable to the Investment Adviser pursuant to the Amended and Restated Investment Advisory and Management Agreement were reasonable in relation to the services to be provided. The board of directors of NMF Holdings did not assign relative weights to the above factors or the other factors considered by it. In addition, the board of directors of NMF Holdings did not reach any specific conclusion on each factor considered, but conducted an overall analysis of these factors. Individual members of the board of directors of NMF Holdings may have given different weights to different factors.

Section 16(a) Beneficial Ownership Reporting Compliance

        Pursuant to Section 16(a) of the Exchange Act, the New Mountain Finance Entities' directors and executive officers, and any persons holding more than 10.0% of its common stock, are required to report their beneficial ownership and any changes therein to the SEC and the New Mountain Finance Entities. Specific due dates for those reports have been established, and the New Mountain Finance Entities are required to report herein any failure to file such reports by those due dates. Based solely upon review of Forms 3, 4 and 5 (and amendments thereto) furnished to the New Mountain Finance Entities during or in respect of the year ended December 31, 2013 and written representations from certain reporting persons, we believe that all Section 16(a) filing requirements applicable to our directors, executive officers, and 10.0% or greater shareholders were satisfied in a timely manner during the year ended December 31, 2013.

Pre-Approval Policy

        The audit committees have established a pre-approval policy that describes the permitted audit, audit-related, consulting services and other services to be provided by Deloitte & Touche LLP, the New Mountain Finance Entities' independent registered public accounting firm. The policy requires that the audit committees pre-approve the audit, non-audit and consulting services performed by the independent auditors in order to assure that the provision of such service does not impair the auditors' independence.

        Any requests for audit, audit-related, tax and other services that have not received general pre-approval must be submitted to the audit committees for specific pre-approval, irrespective of the amount, and cannot commence until such approval has been granted. Normally, pre-approval is provided at regularly scheduled meetings of the audit committees. However, the audit committees may delegate pre-approval authority to one or more of their members. The member or members to whom such authority is delegated shall report any pre-approval decisions to the audit committees at their next scheduled meeting. The audit committees do not delegate their responsibilities to pre-approve services performed by the independent registered public accounting firm to management.

Review with Management

        The audit committees have reviewed the audited financial statements and met and held discussions with management regarding the audited financial statements.

PROPOSAL II: APPROVAL OF WITHDRAWAL OF NMF HOLDINGS' BDC ELECTION

Background

        NMF Holdings is a Delaware limited liability company that has elected to be regulated as a BDC under the 1940 Act. NMF Holdings is externally managed by the Investment Adviser. The Administrator provides the administrative services necessary for NMF Holdings' operations. The Investment Adviser and Administrator are wholly-owned subsidiaries of New Mountain Capital (defined as New Mountain Capital Group, L.L.C. and its affiliates). New Mountain Capital is a firm with a track record of investing in the middle market and with assets under management (which includes amounts committed, not all of which have been drawn down and invested to date) totaling approximately $12.0 billion as of December 31, 2013. NMF Holdings, formerly known as New Mountain Guardian (Leveraged), L.L.C., was originally formed as a subsidiary of New Mountain Guardian AIV, L.P. ("Guardian AIV") by New Mountain Capital in October 2008. Guardian AIV was formed through an allocation of approximately $300.0 million of the $5.1 billion of commitments supporting New Mountain Partners III, L.P., a private equity fund managed by New Mountain Capital. In February 2009, New Mountain Capital formed a co-investment vehicle, New Mountain Guardian Partners, L.P., comprising $20.4 million of commitments. New Mountain Guardian (Leveraged), L.L.C. and New Mountain Guardian Partners, L.P., together with their respective direct and indirect wholly-owned subsidiaries, are defined as the "Predecessor Entities".

        NMFC, a Delaware corporation organized in June 2010, is a holding company with no direct operations of its own, and its only business and sole assets are its ownership of common membership units of NMF Holdings. NMF Holdings is an externally managed, closed-end, non-diversified BDC managed by the Investment Adviser and is the operating company for NMFC's business. On May 19, 2011 each of NMFC and NMF Holdings filed Forms N-54A with the SEC, electing to be regulated as BDCs under the 1940 Act. NMF Holdings, which was organized in Delaware in October 2008, was deemed the co-issuer of the shares of common stock offered by NMFC in its initial public offering of shares of common stock (the "IPO") in May 2011. NMFC used the gross proceeds of the IPO to acquire common membership units in NMF Holdings.

        New Mountain Finance AIV Holdings Corporation ("AIV Holdings") is a Delaware corporation that was originally incorporated on March 11, 2011. Guardian AIV, a Delaware limited partnership, is the sole stockholder of AIV Holdings. AIV Holdings is a closed-end, non-diversified management investment company that has elected to be regulated as a BDC under the 1940 Act. AIV Holdings is a holding company with no direct operations of its own, and until February 3, 2014, its only business and sole asset was its ownership of common membership units of NMF Holdings.

        In connection with the IPO, NMFC and AIV Holdings each entered into a joinder agreement with respect to the Limited Liability Company Agreement, as amended and restated, of NMF Holdings (the "Operating Agreement"), pursuant to which NMFC and AIV Holdings were admitted as members of NMF Holdings. Guardian AIV was the parent of the Operating Company prior to the IPO and, as a result of the transactions completed in connection with the IPO, obtained 20,221,938 common membership units in NMF Holdings, which Guardian AIV contributed to its newly formed subsidiary, AIV Holdings, in exchange for 100 shares of common stock of AIV Holdings, par value $0.01 per share. As a result, Guardian AIV became the sole stockholder of AIV Holdings. Following the IPO, AIV Holdings became a holding company with no direct operations of its own, and its only business and sole asset was its ownership of common membership units of NMF Holdings without any material long-term liabilities. AIV Holdings' only source of cash flow from operations was distributions from NMF Holdings. AIV Holdings had the right to exchange all or any portion of its common membership units in NMF Holdings for shares of NMFC's common stock on a one-for-one basis at anytime.

        This structure was designed to generally prevent NMFC and its stockholders from being allocated taxable income with respect to unrecognized gains that existed at the time of the IPO in the Predecessor Entities' assets, and rather such amounts would be allocated generally to AIV Holdings

25

---

and Guardian AIV. The result was that any distributions made to NMFC's stockholders that may have been attributable to such gains generally would not have been treated as taxable dividends but rather as return of capital.

        Since the IPO through February 3, 2014, NMFC completed five underwritten secondary offerings of its common stock on behalf of AIV Holdings as the selling stockholder. In connection with these five secondary offerings, AIV Holdings tendered an aggregate of 20,221,938 common membership units of NMF Holdings held by AIV Holdings to NMFC in exchange for the net proceeds (after deducting underwriting discounts and commissions) of these five secondary offerings and NMFC issued an aggregate of 20,221,938 shares of its common stock directly to the underwriters for these five secondary offerings. AIV Holdings distributed all of the net proceeds from these five secondary offerings to its sole stockholder, Guardian AIV. With the completion of the final secondary offering on February 3, 2014, as of the Record Date, NMFC now owns 100% of the outstanding common membership units of NMF Holdings, which is now a wholly owned subsidiary of NMFC.

        As a BDC, NMF Holdings has been subject to the 1940 Act, including certain provisions applicable only to BDCs. Accordingly, and after careful consideration of the 1940 Act requirements applicable to BDCs, the cost of 1940 Act compliance and a thorough assessment of NMF Holdings' current business model, NMF Holdings' board of directors has determined that continuation as a BDC is not in the best interests of NMF Holdings at the present time. Specifically, given that NMF Holdings intends to withdraw NMF Holdings' election to be treated as a BDC under the 1940 Act and amend its Operating Agreement such that NMF Holdings will remain a wholly owned subsidiary of NMFC with the sole purpose of serving as a special purpose vehicle for NMF Holdings' existing credit facilities, and NMFC will assume, with the necessary stockholder approval, all other operating activities previously undertaken by NMF Holdings under the management of the Investment Adviser (the "Proposed Restructuring"). All of the current entities that will remain underneath NMFC after the Proposed Restructuring will be wholly-owned subsidiaries of NMFC and are expected to be consolidated with NMFC for both 1940 Act and financial statement reporting purposes, subject to any financial statement adjustments required in accordance with U.S. generally accepted accounting principles. In addition, the board of directors has approved and declared advisable the termination of NMF Holdings' registration under Section 12(g) of the Securities Exchange Act of 1934, as amended (the "1934 Act").

Timeline

        If the Sole Unit Holder of NMF Holdings, and the stockholders of NMFC, voting on a pass-through basis, affirmatively vote to authorize the board of directors to withdraw NMF Holdings' election to be regulated as a BDC, the withdrawal will become effective upon receipt by the Securities and Exchange Commission ("SEC") of NMF Holdings' notification for withdrawal on Form N-54C. As of the date hereof, the board of directors believes that NMF Holdings meets the requirements for filing the notification to withdraw its election to be regulated as a BDC, upon the receipt of the approval of NMFC's stockholders and NMF Holdings' Sole Unit Holder. NMF Holdings anticipates filing the Form N-54C with the SEC as soon as practicable after receipt of approval of NMFC's stockholders and NMF Holdings' Sole Unit Holder. After the notification for withdrawal of NMF Holdings' BDC election is filed with the SEC, NMF Holdings will no longer be subject to the regulatory provisions of the 1940 Act applicable to BDCs generally, including regulations related to insurance, custody, composition of its board of directors, affiliated transactions and any compensation arrangements.

        After NMF Holdings files the Form N-54C with the SEC, NMF Holdings will then file a Form 15 with the SEC to terminate NMF Holdings' registration under Section 12(g) of the 1934 Act. NMF Holdings will then amend its Operating Agreement such that the board of directors of NMF Holdings will be dissolved, and NMF Holdings remains a wholly owned subsidiary of NMFC with the sole purpose of serving as a special purpose vehicle for NMF Holdings' existing credit facilities. As a special purpose entity, NMF Holdings will be bankruptcy-remote and non-recourse to NMFC. In addition, the

26

assets that NMF Holdings will hold will continue to be used to secure NMF Holdings' current credit facilities.

Risks Associated with the Withdrawal of Election to be Regulated as a BDC

        Although NMFC will remain a BDC following NMF Holdings' withdrawal of BDC election, when NMF Holdings ceases to be a BDC, NMFC, its sole unit holder, will lose certain protections, including the following:

•

NMF Holdings will no longer be subject to the requirement that it maintain a ratio of assets to senior securities of at least 200.0%;



•

NMF Holdings will no longer be prohibited from protecting any director or officer against any liability to NMF Holdings or NMF Holdings' Sole Unit Holder arising from willful malfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of that person's office;



•

NMF Holdings will no longer be required to provide and maintain a bond issued by a reputable fidelity insurance company to protect it against larceny and embezzlement;



•

NMF Holdings will no longer be required to comply with Section 56 of the 1940 Act by ensuring that a majority of the directors are persons who are not "interested persons," as that term is defined in Section 2(a)(19) of the 1940 Act, and certain persons that would be prevented from serving on NMF Holdings' board of directors if it were a BDC (such as investment bankers) will be able to serve on the NMF Holdings board of directors;



•

NMF Holdings will no longer be subject to provisions of the 1940 Act regulating transactions between BDCs and certain affiliates and restricting NMF Holdings' ability to issue warrants and options;



•

NMF Holdings will no longer be subject to provisions of the 1940 Act prohibiting the issuance of securities at below net asset value; and



•

NMF Holdings will no longer be subject to the other provisions and protections set forth in Sections 55 through 64 of the 1940 Act and the rules and regulations promulgated under the 1940 Act.

        The stockholders of NMFC still retain the benefit of these protections, however, as NMFC will remain a BDC and therefore subject to continued regulation under the 1940 Act. After withdrawal of NMF Holdings' election to be treated as a BDC, NMF Holdings intends to terminate its registration under Section 12(g) of the 1934 Act. As a result, NMF Holdings will no longer be required to file periodic reports on Form 10-K, Form 10-Q, Form 8-K, proxy statements and other reports required under the 1934 Act. NMFC will continue to file periodic reports on Form 10-K, Form 10-Q, Form 8-K, proxy statements and other reports required under the 1934 Act. Despite its withdrawal of BDC election and it's termination of its registration under Section 12(g) of the 1934 Act, NMF Holdings' Board of Directors will still be subject to customary principles of fiduciary duty with respect to NMF Holdings and its Sole Unit Holder.

Vote Required

        Section 58 of the 1940 Act provides that a BDC may not withdraw from election as a BDC unless it is authorized to do so by a majority of its issued and outstanding voting securities. For purposes of this proposal, the vote of a "majority of the outstanding shares" means the vote of (A) 67.0% or more of the Voting Securities present at the Annual Meeting, if the holders of more than 50.0% of the outstanding Voting Securities are present or represented by proxy or (B) more than 50.0% of the outstanding Voting Securities, whichever is the less.

        THE BOARD OF DIRECTORS OF NMF HOLDINGS RECOMMENDS THAT YOU VOTE "FOR" THE PROPOSAL TO AUTHORIZE THE BOARD OF DIRECTORS OF NMF HOLDINGS TO WITHDRAW NMF HOLDINGS' ELECTION TO BE TREATED AS A BUSINESS DEVELOPMENT COMPANY UNDER THE INVESTMENT COMPANY ACT OF 1940.

PROPOSAL III: APPROVAL THE INVESTMENT ADVISORY AND MANAGEMENT AGREEMENT BETWEEN NEW MOUNTAIN FINANCE CORPORATION AND NEW MOUNTAIN FINANCE HOLDINGS, LLC'S CURRENT INVESTMENT ADVISER, NEW MOUNTAIN FINANCE ADVISERS BDC, L.L.C.

Background

        As discussed above, in connection with the Proposed Restructuring, the board of directors of NMFC recommends the approval of an investment advisory and management agreement between NMFC and the Investment Adviser, which presently serves as the investment adviser to NMF Holdings.

        NMFC currently owns all of the outstanding common membership units of NMF Holdings. Subject to the necessary stockholder approvals, NMF Holdings intends to withdraw its BDC election and NMFC intends to enter into the New Advisory Agreement in substantially the same form as the investment advisory and management agreement between NMF Holdings and the Investment Adviser (the "Current Advisory Agreement"). Following completion of the Proposed Restructuring, subject to the necessary stockholder approvals, NMFC will enter into the New Advisory Agreement and will, from that point on, be managed by the Investment Adviser. A marked copy of the New Advisory Agreement, indicating changes from the Current Advisory Agreement, is attached hereto as Annex A.

Information About the Investment Adviser

        The Investment Adviser is a Delaware limited liability company that is registered as an investment adviser under the Investment Advisers Act of 1940, as amended (the "Advisers Act"). The Investment Adviser was formed in 2010 and has over $1.14 billion in assets under management as of December 31, 2013, all of which are the consolidated assets of NMF Holdings. As of December 31, 2013 the Investment Adviser was supported by approximately 100 staff members, including over 60 investment professionals. During the year ended December 31, 2013, the Investment Adviser received approximately $32.5 million in fees from NMF Holdings under the Current Advisory Agreement, which includes capital gain incentive fees owed under the Current Advisory Agreement as of December 31, 2013, and the Administrator received approximately $1.8 million in direct reimbursements under the Administration Agreement.

        The sole member of the Investment Adviser is New Mountain Capital Group, L.L.C., which is also the managing member of New Mountain Capital, L.L.C. The Investment Adviser is ultimately controlled by Steven B. Klinsky, the chairman of the New Mountain Finance Entities, through Mr. Klinsky's sole membership interest in New Mountain Capital Group, L.L.C. The Investment Adviser does not have any officers or directors. Robert A. Hamwee, the chief executive officer and president of the New Mountain Finance Entities, is a managing director of New Mountain Capital, L.L.C. David M. Cordova, serves as the chief financial officer and treasurer of the New Mountain Finance Entities, is a director of New Mountain Capital, L.L.C. Paula A. Bosco, the chief compliance officer, chief regulatory counsel and corporate secretary of the New Mountain Finance Entities, is a managing director, chief regulatory counsel and chief compliance officer of New Mountain Capital, L.L.C. John R. Kline, chief operating officer and executive vice president of the New Mountain Finance Entities, is a managing director of New Mountain Capital, L.L.C. The business address of the Investment Adviser, New Mountain Capital Group, L.L.C. and Messrs. Klinsky, Hamwee, Weinstein, Cordova, and Kline and Ms. Bosco is 787 Seventh Avenue, 48^th Floor, New York, New York 10019.

        Under the New Advisory Agreement, the Investment Adviser will serve as the external investment adviser to NMFC. The Investment Adviser is registered as an investment adviser under the Investment Advisers Act of 1940. Under the New Advisory Agreement, the Investment Adviser will manage NMFC's investment activities pursuant to an investment advisory agreement with NMFC that satisfies the requirements of Sections 15(a) and (c) of the 1940 Act. Subject to the overall supervision of the board of directors of NMFC, the Investment Adviser will serve as the investment manager to NMFC

28

---

and the investment and exit decisions and day-to-day investment activities of NMFC will be managed by members of the Investment Adviser's senior management.

Summary of the New and Current Advisory Agreements

        Subject to approval of its stockholders, NMFC will enter into the New Advisory Agreement. The terms and conditions of the New Advisory Agreement are identical to the terms and conditions of the Current Advisory Agreement, except that NMFC will replace NMF Holdings as a party to the New Advisory Agreement. Following approval by the stockholders of NMFC in the manner required by the 1940 Act, the New Advisory Agreement will be entered into immediately following the Annual Meeting.

        Advisory and Other Services.    Under the terms of the New Advisory Agreement, the Investment Adviser will have full discretion and authority to manage the assets and liabilities of NMFC and to manage the day-to-day business and affairs of NMFC, in each case in accordance with NMFC's investment objective, policies and restrictions.

Management Services

        The Investment Adviser will serve pursuant to the New Advisory Agreement in accordance with the 1940 Act. Subject to the overall supervision of NMFC board of directors, the Investment Adviser will manage NMFC's day-to-day operations and provide it with investment advisory and management services. Under the terms of the New Advisory Agreement, the Investment Adviser will:

•

determine the composition of NMFC's portfolio, the nature and timing of the changes to its portfolio and the manner of implementing such changes;



•

determine the securities and other assets that NMFC will purchase, retain or sell;



•

identify, evaluate and negotiate the structure of the investments that NMFC makes;



•

execute, monitor and service the investments NMFC makes;



•

perform due diligence on prospective portfolio companies;



•

vote, exercise consents and exercise all other rights appertaining to such securities and other assets on behalf of NMFC; and



•

provide NMFC with such other investment advisory, research and related services as NMFC may, from time to time, reasonably require.

        The Investment Adviser's services under the New Advisory Agreement are not exclusive, and the Investment Adviser (so long as its services to NMFC are not impaired) and/or other entities affiliated with New Mountain Capital, L.L.C. are permitted to furnish similar services to other entities.

Management Fees

        Pursuant to the New Advisory Agreement, NMFC will pay the Investment Adviser a fee for investment advisory and management services consisting of two components—a base management fee and an incentive fee. The cost of both the base management fee payable to the Investment Adviser and any incentive fees paid in cash to the Investment Adviser are borne by NMFC and, as a result, are indirectly borne by NMFC's stockholders.

29

Table of Contents

Base Management Fees

        The base management fee is calculated at an annual rate of 1.75% of gross assets less (i) the borrowings under the senior loan fund's Loan and Security Agreement with Wells Fargo Bank, National Association, dated October 27, 2010, as amended, (the "SLF Credit Facility") and (ii) cash and cash equivalents. The base management fee is payable quarterly in arrears, and is calculated based on the average value of gross assets, borrowings under the SLF Credit Facility, and cash and cash equivalents at the end of each of the two most recently completed calendar quarters, and appropriately adjusted on a pro rata basis for any equity capital raises or repurchases during the current calendar quarter.

Incentive Fees

        The incentive fee consists of two parts. The first part is calculated and payable quarterly in arrears and equals 20.0% of NMFC's "Pre-Incentive Fee Adjusted Net Investment Income" for the immediately preceding quarter, subject to a "preferred return", or "hurdle", and a "catch-up" feature. "Pre-Incentive Fee Net Investment Income" means interest income, dividend income and any other income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, diligence and consulting fees or other fees that NMFC receives from portfolio companies) accrued during the calendar quarter, minus NMFC's operating expenses for the quarter (including the base management fee, expenses payable under the Administration Agreement, as amended and restated, with the Administrator, and any interest expense and distributions paid on any issued and outstanding preferred stock, but excluding the incentive fee). Pre-Incentive Fee Net Investment Income includes, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with payment-in-kind ("PIK") interest and zero coupon securities), accrued income that NMFC has not yet received in cash. Pre-Incentive Fee Net Investment Income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation.

        Under accounting principles generally accepted in the United States of America ("GAAP"), NMFC's IPO did not step-up the cost basis of NMF Holdings' existing investments to fair market value at the IPO date. Since the total value of NMF Holdings' investments at the time of the IPO was greater than the investments' cost basis, a larger amount of amortization of purchase or original issue discount, as well as different amounts in realized gain and unrealized appreciation, may be recognized under GAAP in each period than if the step-up had occurred. This will remain until such predecessor investments are sold or mature in the future. NMF Holdings tracked the transferred (or fair market) value of each of its investments as of the time of the IPO and, for purposes of the incentive fee calculation, adjusted Pre-Incentive Fee Net Investment Income to reflect the amortization of purchase or original issue discount on NMF Holdings' investments as if each investment was purchased at the date of the IPO, or stepped up to fair market value. This is defined as "Pre-Incentive Fee Adjusted Net Investment Income". NMF Holdings also uses the transferred (or fair market) value of each of its investments as of the time of the IPO to adjust capital gains ("Adjusted Realized Capital Gains") or losses ("Adjusted Realized Capital Losses") and unrealized capital appreciation ("Adjusted Unrealized Capital Appreciation") and unrealized capital depreciation ("Adjusted Unrealized Capital Depreciation"). Pursuant to the New Advisory Agreement, NMFC will continue to track the investments in a similar manner.

        Pre-Incentive Fee Adjusted Net Investment Income, expressed as a rate of return on the value of NMFC's net assets at the end of the immediately preceding calendar quarter, will be compared to a "hurdle rate" of 2.0% per quarter (8.0% annualized), subject to a "catch-up" provision measured as of the end of each calendar quarter. The hurdle rate is appropriately pro-rated for any partial periods.

30

---

Table of Contents

The calculation of NMFC's incentive fee with respect to the Pre-Incentive Fee Adjusted Net Investment Income for each quarter is as follows:

•

No incentive fee is payable to the Investment Adviser in any calendar quarter in which NMFC's Pre-Incentive Fee Adjusted Net Investment Income does not exceed the hurdle rate of 2.0% (the "preferred return" or "hurdle").



•

100.0% of NMFC's Pre-Incentive Fee Adjusted Net Investment Income with respect to that portion of such Pre-Incentive Fee Adjusted Net Investment Income, if any, that exceeds the hurdle rate but is less than or equal to 2.5% in any calendar quarter (10.0% annualized) is payable to the Investment Adviser. This portion of NMFC's Pre-Incentive Fee Adjusted Net Investment Income (which exceeds the hurdle rate but is less than or equal to 2.5%) is referred to as the "catch-up". The catch-up provision is intended to provide the Investment Adviser with an incentive fee of 20.0% on all of NMFC's Pre-Incentive Fee Adjusted Net Investment Income as if a hurdle rate did not apply when NMFC's Pre-Incentive Fee Adjusted Net Investment Income exceeds 2.5% in any calendar quarter.



•

20.0% of the amount of NMFC's Pre-Incentive Fee Adjusted Net Investment Income, if any, that exceeds 2.5% in any calendar quarter (10.0% annualized) is payable to the Investment Adviser once the hurdle is reached and the catch-up is achieved.

        The second part will be determined and payable in arrears as of the end of each calendar year (or upon termination of the New Advisory Agreement) and will equal 20.0% of NMFC's Adjusted Realized Capital Gains, if any, on a cumulative basis from inception through the end of each calendar year, computed net of all Adjusted Realized Capital Losses and Adjusted Unrealized Capital Depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fee.

Payment of Expenses

        NMFC's primary operating expenses are the payment of a base management fee and any incentive fees under the New Advisory Agreement and the allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations to the New Mountain Finance Entities under the Administration Agreement. NMFC bears all other expenses of the New Mountain Finance Entities' operations and transactions, including (without limitation) fees and expenses relating to:

•

organizational and offering expenses;



•

the investigation and monitoring of the New Mountain Finance Entities' investments;



•

the cost of calculating net asset value;

Term, Continuance and Termination.

        The New Advisory Agreement provides that the New Advisory Agreement will remain in force for two years from the date on which it first becomes effective, and thereafter shall continue automatically for successive annual periods, provided that such continuance is specifically approved at least annually by (A) the vote of the boards of directors, or by the vote of a majority of the outstanding Voting Securities of NMFC and (B) the vote of a majority of NMFC's board of directors who are not parties to the New Advisory Agreement or "interested persons" (as such term is defined in Section 2(a)(19) of the 1940 Act, or "Disinterested Directors") of any such party, in accordance with the requirements of the 1940 Act. Notwithstanding the foregoing, the New Advisory Agreement may be terminated (i) by NMFC at any time, without the payment of any penalty, upon giving the Investment Adviser 60 days' written notice (which notice may be waived by the Investment Adviser), provided that such termination by NMFC shall be directed or approved by the vote of a majority of the directors of NMFC in office at the time or by the vote of the holders of a majority of the Voting Securities of NMFC at the time outstanding and entitled to vote, or (ii) by the Investment Adviser on 60 days' written notice to NMFC (which notice may be waived by NMFC).

Board of Directors Consideration of the New Advisory Agreement

        At an in-person meeting of NMFC's board of directors held on March 25, 2014, the NMFC Board considered the approval of the New Advisory Agreement. The board of directors believes that the terms and conditions of the New Advisory Agreement are fair to, and in the best interests of, NMFC and its stockholders. The NMFC's board of directors also believes that there will be no change in the services provided by the Investment Adviser to NMFC from the services previously provided by the Investment Adviser to NMF Holdings, including the investment process, operations or investment advisory services to NMFC under the New Advisory Agreement. In reaching a decision to approve the New Advisory Agreement, the board of directors considered, among other things:

•

the nature, quality and extent of the advisory and other services to be provided to NMFC by the Investment Adviser;



•

the investment performance of NMFC and the Investment Adviser;

32

---

Table of Contents

•

the costs of the services to be provided by the Investment Adviser and the profits to be realized the Investment Adviser and its affiliates from its relationship with NMFC;



•

the extent to which economies of scale would be realized as NMFC grows, and whether the fees payable under the New Advisory Agreement reflect these economies of scale for the benefit of the NMFC's stockholders, compared against the Investment Adviser's need to retain additional advisory personnel and commit further resources to its management of NMFC's portfolio as the portfolio continues to grow, in view of the nature of the private debt and equity investments NMFC's generally targets;



•

comparative data with respect to advisory fees or similar expenses paid by other business development companies with similar investment objectives;



•

NMFC's historical and projected operating expenses and expense ratio compared to business development companies with similar investment objectives;



•

any existing and potential sources of indirect income to the Investment Adviser or the Administrator from their relationships with NMFC and the profitability of those relationships, including through the New Advisory Agreement and the Administration Agreement;



•

information about the services to be performed and the personnel performing such services under the New Advisory Agreement;



•

the organizational capability and financial condition of the Investment Adviser and its affiliates;



•

the Investment Adviser's practices regarding the selection and compensation of brokers that may execute NMFC's portfolio transactions and the brokers' provision of brokerage and research services to the Investment Adviser; and



•

the possibility of obtaining similar services from other third party service providers or through an internally managed structure.

        Based on the information reviewed and the discussions, NMFC's board of directors, including a majority of the Disinterested Directors, concluded that fees payable to the Investment Adviser pursuant to the New Advisory Agreement are reasonable in relation to the services to be provided, approved the New Advisory Agreement as being in the best interests of NMFC and its stockholders and directed that the approval of the New Advisory Agreement be submitted to the NMFC stockholders for approval with the NMFC board of directors recommendation that stockholders vote for the approval of the New Advisory Agreement. The NMFC board of directors did not assign relative weights to the above factors or the other factors considered by it. In addition, the NMFC board of directors did not reach any specific conclusion on each factor considered, but conducted an overall analysis of these factors. Individual members of the NMFC board of directors may have given different weights to different factors.

Required Vote

        Approval of this proposal requires the affirmative vote of 67.0% or more of the Voting Securities of the NMFC stockholders present at the Annual Meeting, if the holders of more than 50.0% of the outstanding Voting Securities of NMFC are present or represented by proxy, or the affirmative vote of more than 50.0% of the outstanding Voting Securities of NMFC, whichever is less. Broker Non-Votes (i.e., proxies from brokers or nominees indicating that they have not received instructions from the beneficial owners on an item for which the brokers or nominees do not have discretionary power to vote) and abstentions will have the effect of a vote against this proposal.

2.     Company's Responsibilities and Expenses Payable by the Company.

        All investment professionals of the Adviser and their respective staffs, when and to the extent engaged in providing investment advisory and management services hereunder, and the compensation and routine overhead expenses of such personnel allocable to such services, will be provided and paid for by the Adviser and not by the Company.

Finance, the Company and New Mountain Finance Administration, LLC (the "Administrator") based upon New Mountain Finance's and the Company's allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations to New Mountain Finance and the Company under the administration agreement, including the allocable portion of the compensation of New Mountain Finance's and the Company's chief financial officer and chief compliance officer and their respective staffs.

3.     Compensation of the Adviser.

        The Company agrees to pay, and the Adviser agrees to accept, as compensation for the services provided by the Adviser hereunder, a base management fee ("Base Management Fee") and an incentive fee ("Incentive Fee") as hereinafter set forth. The Company shall make any payments due hereunder to the Adviser or to the Adviser's designee as the Adviser may otherwise direct. To the extent permitted by applicable law, the Adviser may elect, or the Company may adopt a deferred compensation plan pursuant to which the Adviser may elect, to defer all or a portion of its fees hereunder for a specified period of time.

        (a)   The Base Management Fee shall be calculated at an annual rate of 1.75% of the Company's gross assets, as presented in the Company's consolidated financial statements prepared in conformity with accounting principles generally accepted in the United States of America, less (i) the outstanding indebtedness under the Second Amended and Restated Loan and Security Agreement dated March 9, 2011, by and among New Mountain Finance SPV Funding, L.L.C. as the borrower, Wells Fargo Securities, LLC, as the Administrative Agent, and Wells Fargo Bank, National Association, as the Collateral Custodian, as such document may be amended from time to time, and (ii) cash and cash equivalents. For services rendered under this Aagreement, the Base Management Fee will be payable quarterly in arrears. The Base Management Fee will be calculated based on the average value of the Company's gross assets at the end of each of the two most recently completed calendar quarters, and appropriately adjusted on a pro rata basis for any equity capital raised or repurchased during the current calendar quarter. Base Management Fees for any partial month or quarter will be appropriately pro rated.

        (b)   The Incentive Fee shall consist of two parts, as follows:

(i)

One part will be calculated and payable quarterly in arrears based on the Company's "Pre-Incentive Fee Net Investment Income" for the immediately preceding calendar quarter. For this purpose, Pre-Incentive Fee Net Investment Income means interest income, dividend income and any other income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, diligence and consulting fees or other fees that the Company receives from portfolio companies) accrued by the Company during the calendar quarter, minus the Company's operating expenses for the quarter (including the Base Management Fee, expenses payable under the administration agreement with the Administrator, and any interest expense and distributions paid on any issued and outstanding preferred membership units, but excluding the Incentive Fee). Pre-Incentive Fee Net Investment Income includes, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with pay in kind interest and zero coupon securities), accrued income that the Company has not yet received in cash. Pre-Incentive Fee Net Investment Income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. Pre-Incentive Fee Net Investment Income, expressed as a rate of return on the value of the Company's net assets at the end of the immediately preceding calendar quarter, will be compared to a "hurdle rate" of 2% per quarter (8% annualized), subject to a "catch-up" provision measured as of the end of each calendar quarter. The Company's net investment income used to calculate this part of the Incentive Fee is also included in the amount of its gross assets used to calculate the 1.75% Base Management Fee. The Company will keep track of the transferred value of each of its

A-3

Table of Contents

assets aquired on May 19, 2011 and for purposes of the incentive fee calculation, adjust Pre-Incentive Fee Net Investment Income to eliminate the effect of additional amortization of purchase discount or original issue discount taken into account in each period as a result of the lower original purchase price of assets acquired on May 19, 2011 as to the transferred value of that date. The Company will pay the Adviser an Incentive Fee with respect to the Company's Pre-Incentive Fee Net Investment Income in each calendar quarter as follows: (1) no Incentive Fee in any calendar quarter in which the Company's Pre-Incentive Fee Net Investment Income does not exceed the hurdle rate of 2% (the "preferred return" or "hurdle"); (2) 100% of the Company's Pre-Incentive Fee Net Investment Income with respect to that portion of such Pre-Incentive Fee Net Investment Income, if any, that exceeds the hurdle rate but is less than or equal to 2.5% in any calendar quarter (10% annualized); this portion of the Pre-Incentive Fee Net Investment Income (which exceeds the hurdle rate but is less than or equal to 2.5%) is referred to herein as the "catch-up." The "catch-up" is meant to provide the Adviser with an incentive fee of 20% on all of the Company's Pre-Incentive Fee Net Investment Income as if a hurdle rate did not apply when the Company's Pre-Incentive Fee Net Investment Income exceeds 2.5% in any calendar quarter; and (3) 20% of the amount of the Company's Pre-Incentive Fee Net Investment Income, if any, that exceeds 2.5% in any calendar quarter (10% annualized) payable to the Adviser once the hurdle is reached and the catch-up is achieved, (20% of all Pre-Incentive Fee Net Investment Income thereafter is allocated to the Adviser). These calculations will be appropriately pro rated for any period of less than three months and adjusted for any equity capital raises or repurchases during the relevant calendar quarter.

(ii)

The second part of the Incentive Fee (the "Capital Gains Fee") will be determined and payable in arrears as of the end of each calendar year (or upon termination of this Agreement as set forth below), commencing on December 31, 2011, and will equal 20% of the Company's realized capital gains, if any, on a cumulative basis from inception through the end of each calendar year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain Incentive Fees; provided that the Incentive Fee determined as of December 31, 2011 will be calculated for a period of shorter than twelve calendar months to take into account any realized capital gains computed net of all realized capital losses and unrealized capital depreciation from inception. The Company will keep track of the transferred value of each of its assets aquired on May 19, 2011 and for purposes of the second part of the incentive fee calculation, adjust realized capital gains, realized capital losses, unrealized capital appreciation and unrealized capital depreciation to eliminate the effect of the difference in cost basis and calculate these amounts "as if" the GAAP built-in gain for each asset was zero on May 19, 2011.



(iii)

The last day of each calendar quarter in which the Adviser is entitled to receive an Incentive Fee shall be referred to herein as an "Incentive Fee Date."

4.     Payment of Incentive Fee in Common Membership UnitsStock.

        (a)   The Company agrees to pay, and the Adviser agrees to accept, (x) the portion of the Incentive Fee that equals 50% of the After-Tax Amount (as defined below) in shares (each, a "Share") of the Company's common membership unitsstock, par value $0.01 per share (the "Common Membership UnitsStock"), which Common Membership Units will be exchangeable into shares of New Mountain Finance's common stock ("NM Finance Common Stock") on a one-for-one basis, provided that the Securities and Exchange Commission has granted the Company and the Adviser an exemptive order under both the Investment Company Act and the Securities Exchange Act of 1934, as amended (the "Exchange Act") in a form acceptable to the Company and the Adviser, and (y) the remainder of the Incentive Fee in cash. Unless and until such exemptive relief is granted, the Company will pay the Adviser the entire Incentive Fee in cash. If such exemptive relief is granted, the number of Common

A-4

Table of Contents

Membership UnitsShares payable to the Adviser for its Incentive Fee will be calculated based on the greater of (i) the net asset value, or (ii) the market price of NM Financethe Company's Common Stock, and in accordance with such restrictions and conditions as required by the exemptive orders. The After-Tax Amount equals 100% of the Incentive Fee minus the amount of the Assumed Tax Liability. The Assumed Tax Liability equals the product of (x) the maximum combined U.S. federal, New York State and New York City tax rate applicable to an individual on ordinary income, and (y) 100% of the Incentive Fee.

        (b)   The Adviser agrees that until the expiration of the Lock-Up Period (as defined below) applicable to Common Membership UnitsShares issued pursuant to Section 4(a), the Adviser will not offer, sell, contract to sell, pledge, grant any option to purchase, exchange, convert, make any short sale or otherwise dispose of such Common Membership UnitsShares, or any options or warrants to purchase such Common Membership UnitsShares, or any securities convertible into, exchangeable for or that represent the right to receive such Common Membership UnitsShares, or enter into a transaction which would have the same effect or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of such Common Membership UnitsShares. The foregoing restrictions are expressly agreed to preclude the Adviser from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of any Common Membership UnitsShares subject to the Lock-Up Period and held by the Adviser, even if such Common Membership UnitsShares would be disposed of by someone other than the Adviser. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Common Membership UnitsShares or with respect to any security that includes, relates to, or derives any significant part of its value from such Common Membership UnitsShares.(ii)

        For purposes of this Section 4(b), with respect to those Common Membership UnitsShares, if any, payable on any particular Incentive Fee Date, the term "Lock-Up Period" shall mean: (1) with respect to one-third of the Common Membership UnitsShares payable on such Incentive Fee Date, the period beginning on the Incentive Fee Date and ending on the first anniversary of such Incentive Fee Date, (2) with respect to one-third of the Common SharesMembership Units payable on such Incentive Fee Date, the period beginning on the Incentive Fee Date and ending on the second anniversary of such Incentive Fee Date, and (3) with respect to one-third of the Common SharesMembership Units payable on such Incentive Fee Date, the period beginning on the Incentive Fee Date and ending on the third anniversary of such Incentive Fee Date.

(i)

Notwithstanding the foregoing, the Adviser may (i) convert the Common Membership Units into NM Finance Common Stock provided such NM Finance Common Stock is otherwise subject to the same Lock-Up Period described above, and (ii) transfer Common Membership Units or NM Finance Common StockShares to any affiliate of the Adviser, as defined under the Investment Company Act, or an employee of any such affiliate, provided that such affiliate or employee agrees to be bound by the restrictions set forth in Section 4(b) hereof by executing an agreement substantially in the form attached as Exhibit A.



(ii)

In the event this Agreement is terminated by the Company, the lock-up provisions with respect to any sShares of NM Finance Common Stock received by the Adviser or its transferees pursuant to this Agreement shall immediately expire.

5.     Covenants of the Adviser.

6.     Excess Brokerage Commissions.

        The Adviser is hereby authorized, to the fullest extent now or hereafter permitted by law, to cause the Company to pay a member of a national securities exchange, broker or dealer an amount of commission for effecting a securities transaction in excess of the amount of commission another member of such exchange, broker or dealer would have charged for effecting that transaction, if the Adviser determines in good faith, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, and operational facilities of the firm and the firm's risk and skill in positioning blocks of securities, that such amount of commission is reasonable in relation to the value of the brokerage and/or research services provided by such member, broker or dealer, viewed in terms of either that particular transaction or its overall responsibilities with respect to the Company's portfolio.

7.     Limitations on the Employment of the Adviser.

        The services of the Adviser to the Company are not exclusive, and the Adviser may engage in any other business or render similar or different services to others including, without limitation, the direct or indirect sponsorship or management of other investment based accounts or commingled pools of capital, however structured, having investment objectives similar to those of the Company, so long as its services to the Company hereunder are not impaired thereby, and nothing in this Agreement shall limit or restrict the right of any manager, partner, officer or employee of the Adviser to engage in any other business or to devote his or her time and attention in part to any other business, whether of a similar or dissimilar nature, or to receive any fees or compensation in connection therewith (including fees for serving as a director of, or providing consulting services to, one or more of the Company's portfolio companies, subject to applicable law). So long as this Agreement or any extension, renewal or amendment remains in effect, the Adviser shall be the only investment adviser for the Company. The Adviser assumes no responsibility under this Agreement other than to render the services called for hereunder. It is understood that directors, officers, employees and shareholders of the Company are or may become interested in the Adviser and its affiliates, as directors, officers, employees, partners, stockholders, members, managers or otherwise, and that the Adviser and directors, officers, employees, partners, stockholders, members and managers of the Adviser and its affiliates are or may become similarly interested in the Company as shareholders or otherwise.

8.     Responsibility of Dual Directors, Officers and/or Employees.

(the "Adviser") under which the Adviser agreed to accept and the Company agreed to pay the Adviser a portion of its Incentive Fee (as such term is defined in the Agreement) in shares of the Company's common membership unitsstock (each, a "Share")(the "Common Membership Units"), and the Adviser further agreed not to offer, sell, pledge or otherwise dispose of such Common Membership UnitsShares except in accordance with the Agreement.

        In connection with any transfers by the Adviser to the undersigned of any such Common Membership UnitsShares, as permitted by the Agreement (the "Transferred UnitsShares"), the undersigned agrees that during the Lock-Up Period specified in the Agreement applicable to the Transferred SharesUnits, the undersigned will not offer, sell, contract to sell, pledge, grant any option to purchase, exchange, convert, make any short sale or otherwise dispose of any of such Transferred SharesUnits, or any options or warrants to purchase such Transferred UnitsShares, or any securities convertible into, exchangeable for or that represent the right to receive such Transferred UnitsShares, or enter into a transaction which would have the same effect or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of such Transferred UnitsShares. The foregoing restrictions are expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of any Transferred UnitsShares subject to the Lock-Up Period, even if such Transferred SharesUnits would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Transferred UnitsShares or with respect to any security that includes, relates to, or derives any significant part of its value from such Transferred UnitsShares.

        Notwithstanding the foregoing, the undersigned may transfer the Transferred Units Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, or (iii) with the prior written consent of the Company. For purposes of this agreement, "immediate family" shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, if the undersigned is a corporation, limited liability company, partnership (including a limited partnership) or other entity, such corporation, limited liability company, partnership (including a limited partnership) or other entity may transfer the Transferred SharesUnits to any wholly-owned subsidiary of such corporation, limited liability company, partnership (including a limited partnership) or other entity; provided, however, that in any such case, it shall be a condition to the transfer that the transferee execute an agreement stating that the

transferee is receiving and holding such Transferred UnitsShares subject to the provisions of this agreement and there shall be no further transfer of such Transferred UnitsShares except in accordance with this agreement, and provided further that any such transfer shall not involve a disposition for value. The undersigned now has, and, except as contemplated by clause (i), (ii), or (iii) above, for the duration of this agreement will have, good and marketable title to the Transferred SharesUnits, free and clear of all liens, encumbrances, and claims whatsoever.

        The undersigned understands that the Company and the Adviser are relying upon this agreement. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned's heirs, legal representatives, successors, and assigns.
