Our Board of Directors has set March 28, 2014 as the record date (the “Record Date”) for this consent. As a result, this proposal will be approved when we have received the consent to the approval of this proposal from the holders of record of a majority of our outstanding common stock as of the Record Date.

    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.

            Our governance guidelines, which are available on the New Mountain Finance Entities' website athttp://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.

    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 holders 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 holders 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 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 holders, 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;

      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 and AIV Holdings have no assets other than their ownership of units of NMF Holdings and have no material long-term liabilities, NMFC and AIV Holdings look to the assets of NMF Holdings for purposes of satisfying these requirements. For example, the NMF


    Table of Contents

    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, a compensation committee and a valuation committee. The members of each committee have been appointed by the 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 2012, the boards of directors of the New Mountain Finance Entities held eight boards of directors meetings, five audit committee meetings, five nominating and corporate governance committee meetings, two compensation committee meetings and eight valuation committee meetings. 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 holders.

    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 athttp://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 athttp://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'


    Table of Contents

    stockholders/unit holders, 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 holders. 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 holders. 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 holders 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 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 holders.

    Compensation Committees

            The compensation 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 athttp://www.newmountainfinance.com. The charters set forth the responsibilities of the compensation committees. The compensation committees are responsible for periodically reviewing director compensation and recommending any appropriate changes to the boards of directors. In addition, although the New Mountain Finance Entities do not directly compensate their executive


    Table of Contents

The compensation committees have the authority to engage compensation consultants, although they do not currently do so, and to delegate their duties and responsibilities to a member or to a subcommittee of the compensation committees. The compensation 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. Alfred F. Hurley, Jr. serves as chairman of the compensation committees.

    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 athttp://www.newmountainfinance.com.

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.

    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

            Together, NMFC and AIV Holdings own all the outstanding units of NMF Holdings. As of the Record Date, NMFC and AIV Holdings owned approximately 60.0% and 40.0%, respectively, of the 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 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, as amended and restated (the "Administration Agreement"), with the Administrator. 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 the New Mountain Finance Entities' 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 expenses, 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.

            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, AIV 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, AIV Holdings, the Investment Adviser and the Administrator, will have no legal right to the New Mountain and the New Mountain Finance names.

            NMFC and AIV Holdings have entered into joinder agreements with respect to the Amended and Restated Limited Liability Company Agreement, as amended and restated, of NMF Holdingsthe Operating Company, pursuant to which NMFC and AIV Holdings were admitted as members of the NMF Holdings. ConcurrentlyOperating Company.  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 closingIPO, obtained 20,221,938 common membership units in the Operating Company, which Guardian AIV contributed to its newly formed subsidiary, AIV Holdings, in exchange for 100 shares of NMFC's initial publiccommon 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 the Operating Company without any material long-term liabilities. AIV Holdings’ only source of cash flow from operations was distributions from the Operating Company.  AIV Holdings had the right to exchange all or any portion of its common membership units in the Operating Company for shares of NMFC’s common stock on a one-for-one basis at any time.



    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 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 the completion of the final secondary offering on February 3, 2014, NMFC sold 2,172,000completed 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 the Operating Company 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, AIV Holdings no longer owns any common membership units of the Operating Company.

    As a BDC, AIV Holdings has been subject to the 1940 Act, including certain executives and employeesprovisions applicable only to BDCs, although it is exempted from certain provisions of the 1940 Act applicable to registered closed-end investment companies. BDCs generally are provided greater flexibility with respect to management compensation, capital structure, transactions among affiliates and other individuals affiliated with, New Mountain Capital, L.L.C. inmatters than registered closed-end investment companies.  Nevertheless, as a separate private placement at the initial public offering price per share.

            NMFC entered into a Registration Rights Agreement withBDC, AIV Holdings Steven B. Klinsky (the Chairmanremains subject to significant regulation of our boardsits activities.  Accordingly, and after careful consideration of directors), an entity relatedthe 1940 Act requirements applicable to Steven B. KlinskyBDCs, the cost of 1940 Act compliance and a thorough assessment of AIV Holdings’ current business model, AIV Holdings’ Board of Directors has determined that continuation as a BDC is not in the Investment Adviser. Subject to several exceptions,best interests of AIV Holdings and Guardian AIV at the Investment Adviser havepresent time. Specifically, given that AIV Holdings was formed for the right to require NMFC to register for public resale undersole purpose of holding common membership units of the Securities ActOperating Company and AIV Holdings has disposed of 1933,all of the common membership units of the Operating Company that it was holding as amended, all registerable securities that are heldof the completion of the final secondary offering on February 3, 2014, the Board of Directors of AIV Holdings has approved and declared advisable by anyunanimous written consent the withdrawal of them and that they requestAIV Holdings’ election 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 (andregulated as a related entity) will have the right to "piggyback", or include his own registrable securities in such a registration.

            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.

NMF Holdings will not enter into any agreements unless and until it is satisfied that doing so will not raise concernsBDC under the 1940 Act or, if such concerns exist, NMFAct.  In addition, the Board of Directors has approved and declared advisable for AIV 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.

            In October 2012, NMF Holdings entered into an agreement with North Sea Partners, L.P. ("North Sea") to assist in identifying counterparty investment opportunities for NMF Holdings. Mr. Daniel Hébert, a former director of NMF Holdings, is managing director of North Sea and has joint primary responsibility for carrying out and delivering such services to NMF Holdings on behalf of North Sea.

        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, includingIf a majority of the non-interested directors, concludedCompany’s stockholders sign and submit the accompanying consent to authorize the Board of Directors to withdraw AIV Holdings’ election to be regulated as a BDC, the withdrawal will become effective upon receipt by the Securities and Exchange Commission (“SEC”) of AIV Holdings’ notification of withdrawal on Form N-54C. As of the date hereof, the Board of Directors believes that fees payableAIV Holdings meets the requirements for filing the notification to withdraw its election to be regulated as a BDC, upon the receipt of the necessary stockholder consents. AIV Holdings anticipates filing the Form N-54C with the SEC as soon as practicable after receipt of the necessary stockholder consents.  After the notification of withdrawal of AIV Holdings’ BDC election is filed with the SEC, AIV Holdings will no longer be subject to the Investment Adviser pursuantregulatory 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 AIV Holdings files the Form N-54C with the SEC, AIV Holdings will then file a Form 15 with the SEC to terminate AIV Holdings’ registration under Section 12(g) of the 1934 Act.  After these SEC filings and any other federal or state regulatory or tax filings are made, AIV Holdings will proceed to dissolve under Delaware law by filing a certificate of dissolution in Delaware.

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

    When the Company ceases to be a BDC, the Company’s stockholders will lose certain protections, including the following:

    ·The Company will no longer be subject to the Amended and Restated Investment Advisory and Management Agreement were reasonable in relationrequirement that it maintain a ratio of assets to senior securities of at least 200%;

    ·The Company will no longer be prohibited from protecting any director or officer against any liability to the servicesCompany or the Company’s stockholder arising from willful malfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of that person’s office;

    ·The Company 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;



    ·The Company 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 the Company’s Board of Directors if it were a BDC (such as investment bankers) will be able to serve on the Company’s Board of Directors;

    ·The Company will no longer be subject to provisions of the 1940 Act regulating transactions between BDCs and certain affiliates and restricting the Company’s ability to issue warrants and options;

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

    ·The Company 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.

    In addition, after withdrawal of the Company’s election to be provided. The boardregulated as a BDC, the Company intends to terminate its registration under Section 12(g) of directorsthe 1934 Act. As a result, the Company 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.  However, the Company’s Board of NMF Holdings did not assign relative weightsDirectors will still be subject to customary principles of fiduciary duty with respect to the above factors orCompany and its stockholders until 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 membersCompany dissolves in Delaware.

    Vote Required

    Section 58 of the board1940 Act provides that a BDC may not withdraw from election as a BDC unless it is authorized to do so by a majority of directorsits issued and outstanding voting securities. For purposes of NMF Holdings may have given different weights to different factors.


    Section 16(a) Beneficial Ownership Reporting Compliance

            Pursuant to Section 16(a)this proposal, the vote of a “majority of the Exchange Act,outstanding shares” means the New Mountain Finance Entities' directors and executive officers, and any persons holdingvote of (A) 67% or more of the voting securities voting by consent, if the holders of more than 10.0%50% of itsthe outstanding voting securities of the Company are represented by consent or (B) more than 50% of the outstanding voting securities of the Company, whichever is the less. Since Guardian AIV is the sole stockholder of the Company, receipt of the accompanying consent signed by Guardian AIV will provide the Company with the necessary stockholder approval of this proposal.

    THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS THAT YOU CONSENT TO THE PROPOSAL TO AUTHORIZE THE BOARD OF DIRECTORS OF THE COMPANY TO WITHDRAW THE COMPANY’S ELECTION TO BE REGULATED AS A BUSINESS DEVELOPMENT COMPANY UNDER THE INVESTMENT COMPANY ACT OF 1940.

    SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNER

    Guardian AIV owns 100 shares of the Company’s common stock, are required to report their beneficial ownershippar value $0.01 per share. Guardian AIV is the Company’s sole stockholder and, therefore, owns 100% of the outstanding shares of the Company’s common stock as of March 28, 2014. The Company does not have any changes thereinpreferred stock outstanding.  Guardian AIV has sole voting and investment power with respect 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 respectshares of the year ended December 31, 2012 and written representations from certain reporting persons, we believe that the following director of the New Mountain Finance Entities inadvertently failed to file on a timely basis certain reports requiredCompany’s common stock owned by Section 16(a) of the Exchange Act during the year ended December 31, 2012: Robert Hamwee. Mr. Hamwee filed one late Form 4 involving one transaction. We have no knowledge of a failure of Mr. Hamwee to file a report required under Section 16(a) of the Exchange Act. We believe that all other 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, 2012.
