Exhibit 4.9
 DESCRIPTION OF SECURITIES
 
 The following is a brief description of the securities of New Mountain Finance Corporation (the “Company,” “we,” “our” or “us”), registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This description of our securities does not purport to be complete and is subject to and qualified in its entirety by reference to the applicable provisions of Delaware General Corporation Law (the “DGCL”), and the full text of our charter, bylaws and the relevant indenture and supplemental indenture governing the debt securities described herein.  As of December 31, 2019 and the date hereof, our common stock and the debt securities described herein are the only securities that we have registered under Section 12 of the Exchange Act.
 
 
 A.Common Stock 
 As of December 31, 2019, our authorized capital stock consists of 200,000,000 shares of common stock, par value $0.01 per share, of which 96,827,342 shares are outstanding as of December 31, 2019. Our common stock is listed on the New York Stock Exchange under the ticker symbol "NMFC". No stock has been authorized for issuance under any equity compensation plans. Under Delaware law, our stockholders generally will not be personally liable for our debts or obligations.
 
 Under the terms of our amended and restated certificate of incorporation, all shares of our common stock will have equal rights as to earnings, assets, dividends and voting and, when they are issued, are duly authorized, validly issued, fully paid and nonassessable. Distributions may be paid to the holders of our common stock if, as and when authorized and declared by our board of directors out of funds legally available therefore. Shares of our common stock will have no preemptive, exchange, conversion or redemption rights and are freely transferable, except where their transfer is restricted by federal and state securities laws or by contract. In the event of our liquidation, dissolution or winding up, each share of our common stock would be entitled to share ratably in all of our assets that are legally available for distribution after we pay all debts and other liabilities and subject to any preferential rights of holders of our preferred stock, if any preferred stock is outstanding at such time. Each share of our common stock is entitled to one vote on all matters submitted to a vote of stockholders, including the election of directors. Except as provided with respect to any other class or series of stock, the holders of our common stock will possess exclusive voting power. There are no cumulative voting in the election of directors, which means that holders of a majority of the outstanding shares of common stock are able to elect all of our directors (other than directors to be elected solely by the holders of preferred stock), and holders of less than a majority of such shares are unable to elect any director.
 
 Delaware Law and Certain Certificate of Incorporation and Bylaw Provisions; Anti-Takeover Measures
 
 Certain provisions of our amended and restated certificate of incorporation and amended and restated bylaws, as summarized below, and applicable provisions of the DGCL and certain other agreements to which we are a party may make it more difficult for or prevent an unsolicited third party from acquiring control of us or changing our board of directors and management. These provisions may have the effect of deterring hostile takeovers or delaying changes in our control or in our management. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and in the policies furnished by them and to discourage certain types of transactions that may involve an actual or threatened change in our control. The provisions also are intended to discourage certain tactics that may be used in proxy fights. These provisions, however, could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts.
 
 Classified Board; Vacancies; Removal
 
 The classification of our board of directors and the limitations on removal of directors and filling of vacancies could have the effect of making it more difficult for a third party to acquire us, or of discouraging a third party from acquiring us. Our board of directors is divided into three classes, with the term of one class expiring at each annual meeting of stockholders. At each annual meeting, one class of directors is elected to a three-year term. This provision could delay for up to two years the replacement of a majority of the board of directors.
 
 Our amended and restated certificate of incorporation provides that, subject to the applicable requirements of the Investment Company Act of 1940 (the “1940 Act”) and the rights of any holders of preferred stock, any vacancy on the board of directors, however the vacancy occurs, including a vacancy due to an enlargement of the board, may only be filled by vote a majority of the directors then in office.
 
 A director may be removed at any time at a meeting called for that purpose, but only for cause and only by the affirmative vote of the holders of at least 75.0% of the shares then entitled to vote for the election of the respective director.
 
 Advance Notice Requirements for Stockholder Proposals and Director Nominations.
 
 Our amended and restated bylaws provide that with respect to an annual meeting of stockholders, nominations of persons for election to the board of directors and the proposal of business to be considered by stockholders may be made only (1) by or at the direction of the board of directors or (2) by a stockholder who is entitled to vote at the meeting and who has complied with the advance notice procedures of the amended and restated bylaws. Nominations of persons for election to the board of directors at a special meeting may be made only (1) by or at the direction of the board of directors or (2) provided that the board of directors has determined that directors are elected at the meeting, by
 
 
  
 
 a stockholder who is entitled to vote at the meeting and who has complied with the advance notice provisions of the amended and restated bylaws. The purpose of requiring stockholders to give us advance notice of nominations and other business is to afford our board of directors a meaningful opportunity to consider the qualifications of the proposed nominees and the advisability of any other proposed business and, to the extent deemed necessary or desirable by our board of directors, to inform its stockholders and make recommendations about such qualifications or business, as well as to approve a more orderly procedure for conducting meetings of stockholders. Although our amended and restated bylaws do not give its board of directors any power to disapprove stockholder nominations for the election of directors or proposals recommending certain action, they may have the effect of precluding a contest for the election of directors or the consideration of stockholder proposals if proper procedures are not followed and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors or to approve its own proposal without regard to whether consideration of such nominees or proposals might be harmful or beneficial to us and our stockholders.
 
 Amendments to Certificate of Incorporation and Bylaws.
 
 The DGCL provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation's certificate of incorporation or bylaws, unless a corporation's certificate of incorporation or bylaws requires a greater percentage. Our amended and restated certificate of incorporation provides that the following provisions, among others, may be amended by our stockholders only by a vote of at least two-thirds of the shares of our capital stock entitled to vote:
 
 •the classification of our board of directors; 
 •the removal of directors; 
 •the limitation on stockholder action by written consent; 
 •the limitation of directors' personal liability to us or our stockholders for breach of fiduciary duty as a director; 
 •the ability to call a Special Meeting of Stockholders being vested in our board of directors, the chairperson of our board, our chief executive officer and in the holders of at least fifty (50) percent of the voting power of all shares of our capital stock generally entitled to vote on the election of directors then outstanding subject to certain procedures; and 
 •the amendment provision requiring that the above provisions be amended only with a two-thirds supermajority vote. 
 The amended and restated bylaws generally can be amended by approval of (i) a majority of the total number of authorized directors or (ii) the affirmative vote of the holders of at least two-thirds of the shares of our capital stock entitled to vote.
 
 Calling of Special Meetings by Stockholders
 
 Our certificate of incorporation and bylaws also provide that special meetings of the stockholders may only be called by our board of directors, the chairperson of our board, our chief executive officer or upon the request of the holders of at least 50.0% of the voting power of all shares of our capital stock, generally entitled to vote on the election of directors then outstanding, subject to certain limitations.
 
 Section 203 of the DGCL
 
 We will not be subject to Section 203 of the DGCL, an anti-takeover law. In general, Section 203 prohibits a publicly-held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the "business combination" or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a "business combination" includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. Generally, an "interested stockholder" is a person who, together with affiliates and associates, owns (or within three years prior to the determination of interested stockholder status, did own) 15.0% or more of a corporation's voting stock. In our certificate of incorporation, we have elected not to be bound by Section 203.
 
 B.Debt Securities - 5.75% Notes Due 2023 
 On September 25, 2018, we closed a registered public offering of $50.0 million in aggregate principal amount of our 5.75% unsecured notes due October 1, 2023 (the “5.75% Unsecured Notes “) under an indenture, dated August 20, 2018, as supplemented by a second supplemental indenture thereto, dated September 25, 2018 between us and U.S. Bank National Association, as trustee (together, the “2018B Indenture”). On October 17, 2018, in connection with the registered public offering, we issued an additional $1.8 million aggregate principal amount of the 5.75% Unsecured Notes pursuant to the exercise of an overallotment option by the underwriters of the 5.75% Unsecured Notes.
 
 The 5.75% Unsecured Notes bear interest at an annual rate of 5.75%, payable quarterly on January 1, April 1, July 1 and October 1 of each year, which commenced on January 1, 2019. The 5.75% Unsecured Notes will mature on October 1, 2023 unless earlier redeemed. The 5.75% Unsecured Notes are listed on the New York Stock Exchange and trade under the trading symbol "NMFX."
 
 
 
  
 
 The 5.75% Unsecured Notes are issued in denominations of $25 and integral multiples of $25 in excess thereof. The 5.75% Unsecured Notes will not be subject to any sinking fund and holders of the 5.75% Unsecured Notes will not have the option to have the 5.75% Unsecured Notes repaid prior to the stated maturity date.
 
 Except as set forth under "- Covenants" in this description, neither we nor any of our subsidiaries are subject to any financial covenants under the 2018B Indenture. In addition, neither we nor any of our subsidiaries are restricted under the 2018B Indenture from paying dividends, incurring debt, or issuing or repurchasing our securities but the 2018B Indenture contains a covenant regarding our asset coverage and a covenant regarding our debt-to-equity ratio that would have to be satisfied at the time of our incurrence of additional indebtedness. See "- Covenants" in this description. In addition, we must maintain a Secured Debt Ratio (as defined below) of not greater than 0.70 to 1.00 at all times. See "- Covenants - Maximum Secured Debt" in this description.
 
 No sinking fund is provided for the 5.75% Unsecured Notes and holders of the 5.75% Unsecured Notes have no option to have their 5.75% Unsecured Notes repaid prior to the stated maturity date.
 
 We have the ability to issue indenture securities with terms different from the 5.75% Unsecured Notes and, without the consent of the holders of the 5.75% Unsecured Notes, to reopen the 5.75% Unsecured Notes and issue additional 5.75% Unsecured Notes.
 
 Optional Redemption
 
 The 5.75% Unsecured Notes may be redeemed in whole or in part at any time or from time to time at our option on or after October 1, 2020, upon not less than 30 days nor more than 60 days written notice by mail prior to the date fixed for redemption thereof, at a redemption price of 100% of the outstanding principal amount of the 5.75% Unsecured Notes to be redeemed plus accrued and unpaid interest payments otherwise payable thereon for the then-current quarterly interest period accrued to, but excluding, the date fixed for redemption.
 
 Holders of the 5.75% Unsecured Notes (the “Noteholders”) may be prevented from exchanging or transferring the 5.75% Unsecured Notes when they are subject to redemption. In case any 5.75% Unsecured Notes are to be redeemed in part only, the redemption notice will provide that, upon surrender of such Note, the Noteholders will receive, without a charge, a new Note or 5.75% Unsecured Notes of authorized denominations representing the principal amount of the Noteholders remaining unredeemed 5.75% Unsecured Notes. Any exercise of our option to redeem the 5.75% Unsecured Notes is done in compliance with the 1940 Act, to the extent applicable.
 
 If we redeem only some of the 5.75% Unsecured Notes, the trustee or, with respect to global securities, Depository Trust Company, will determine the method for selection of the particular 5.75% Unsecured Notes to be redeemed, in accordance with the 2018B Indenture and the 1940 Act, to the extent applicable, and in accordance with the rules of any national securities exchange or quotation system on which the 5.75% Unsecured Notes are listed. Unless we default in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the 5.75% Unsecured Notes called for redemption.

 The 5.75% Unsecured Notes are not convertible into or exchangeable for other securities.

 Events of Default
 
 The Noteholders will have rights if an Event of Default occurs in respect of the 5.75% Unsecured Notes and the Event of Default is not cured, as described later in this subsection.
 
 The term "Event of Default" in respect of the 5.75% Unsecured Notes means any of the following:
 
 •We do not pay the principal of (or premium, if any, on) any Note when due and payable at maturity; 
 •We do not pay interest on any Note when due and payable, and such default is not cured within 30 days of its due date; 
 •We remain in breach of any other covenant in respect of the 5.75% Unsecured Notes for 60 days after we receive a written notice of default stating we are in breach (the notice must be sent by either the trustee or holders of at least 25% of the principal amount of the outstanding 5.75% Unsecured Notes); 
 •We file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur and remain undischarged or unstayed for a period of 90 days; or 
 On the last business day of each of twenty-four consecutive calendar months, the 5.75% Unsecured Notes have an asset coverage (as such term is defined in the 1940 Act) of less than 100%, giving effect to any exemptive relief granted to us by the SEC.
 
 An Event of Default for the 5.75% Unsecured Notes may, but does not necessarily, constitute an Event of Default for any other series of debt securities issued under the same or any other indenture. The trustee may withhold notice to the holders of the 5.75% Unsecured Notes of any default, except in the payment of principal or interest, if it in good faith considers the withholding of notice to be in the best interests of the holders.
 
 Remedies if an Event of Default Occurs
 
 If an Event of Default has occurred and is continuing, the trustee or the holders of not less than 25% in principal amount of the 5.75% Unsecured Notes may declare the entire principal amount of all the 5.75% Unsecured Notes to be due and immediately payable, but this does not entitle any holder of 5.75% Unsecured Notes to any redemption payout or redemption premium. If an Event of Default referred to in the second to last bullet point above with respect to us has occurred, the entire principal amount of all of the 5.75% Unsecured Notes will automatically become due and immediately payable. This is called a declaration of acceleration of maturity. In certain circumstances, a declaration of acceleration of maturity may be canceled by the holders of a majority in principal amount of the 5.75% Unsecured Notes if (1) we have deposited with the trustee all amounts due and owing with respect to the 5.75% Unsecured Notes (other than principal or any payment that has become due solely by reason of such acceleration) and certain other amounts, and (2) any other Events of Default have been cured or waived.
 
 
 
  
 
 Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the 2018B Indenture at the request of any holders unless the holders offer the trustee protection from expenses and liability reasonably satisfactory to it (called an "indemnity"). If indemnity reasonably satisfactory to the trustee is provided, the holders of a majority in principal amount of the 5.75% Unsecured Notes may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. The trustee may refuse to follow those directions in certain circumstances. No delay or omission in exercising any right or remedy is treated as a waiver of that right, remedy or Event of Default.
 
 Before the Noteholders are allowed to bypass the trustee and bring their own lawsuit or other formal legal action or take other steps to enforce their rights or protect their interests relating to the 5.75% Unsecured Notes, the following must occur:
 
 •The Noteholders must give the trustee written notice that an Event of Default has occurred and remains uncured; 
 •The holders of at least 25% in principal amount of all the 5.75% Unsecured Notes must make a written request that the trustee take action because of the default and must offer the trustee indemnity, security, or both reasonably satisfactory to it against the cost and other liabilities of taking that action; 
 •The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity and/or security; and 
 •The holders of a majority in principal amount of the 5.75% Unsecured Notes must not have given the trustee a direction inconsistent with the above notice during that 60-day period. 
 However, the Noteholders are entitled at any time to bring a lawsuit for the payment of money due on their 5.75% Unsecured Notes on or after the due date.
 
 Modification or Waiver
 
 There are three types of changes we can make to the 2018B Indenture and the 5.75% Unsecured Notes issued thereunder:
 
 Changes Requiring the Noteholders’ Approval
 
 First, there are changes that we cannot make to the 5.75% Unsecured Notes without the specific approval of the Noteholders. The following is a list of those types of changes:
 
 •change the stated maturity of the principal of (or premium, if any, on) or any installment of principal of, or interest on, the 5.75% Unsecured Notes; 
 •reduce any amounts due on the 5.75% Unsecured Notes or reduce the rate of interest on the 5.75% Unsecured Notes; 
 •reduce the amount of principal payable upon acceleration of the maturity of a Note following a default; 
 •change the place or currency of payment on a Note; 
 •impair the Noteholders right to sue for payment; 
 •reduce the percentage of holders of 5.75% Unsecured Notes whose consent is needed to modify or amend the 2018B Indenture; and 
 •reduce the percentage of holders of 5.75% Unsecured Notes whose consent is needed to waive compliance with certain provisions of the 2018B Indenture or to waive certain defaults or reduce the percentage of holders of 5.75% Unsecured Notes required to satisfy quorum or voting requirements at a meeting of holders of the 5.75% Unsecured Notes. 
 Changes Not Requiring Approval
 
 The second type of change does not require any vote by the holders of the 5.75% Unsecured Notes. This type is limited to clarifications and certain other changes that would not adversely affect holders of the 5.75% Unsecured Notes in any material respect.
 
 Changes Requiring Majority Approval
 
 Any other change to the 2018B Indenture and the 5.75% Unsecured Notes would require the following approval:
 
 •if the change affects only the 5.75% Unsecured Notes, it must be approved by the holders of a majority in principal amount of the 5.75% Unsecured Notes; and 
 •if the change affects more than one series of debt securities issued under the same 2018B Indenture, it must be approved by the holders of a majority in principal amount of all of the series affected by the change, with all affected series voting together as one class for this purpose. 
 
  
 
 
 In each case, the required approval must be given by written consent.
 
 The holders of a majority in principal amount of all of the series of debt securities issued under an indenture, voting together as one class for this purpose, may waive our compliance with some of our covenants in that indenture. However, we cannot obtain a waiver of a payment default or of any of the matters covered by the bullet points included above under "- Changes Requiring the Noteholders’ Approval."
 
 Further Details Concerning Voting
 
 When taking a vote, we will use the following rules to decide how much principal to attribute to the 5.75% Unsecured Notes:
 
 The 5.75% Unsecured Notes will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust money for their payment or redemption or if we or any affiliate of ours own any 5.75% Unsecured Notes. The 5.75% Unsecured Notes will also not be eligible to vote if they have been fully defeased as described under "- Defeasance - Full Defeasance" below.
 
 We will generally be entitled to set any day as a record date for the purpose of determining the holders of the 5.75% Unsecured Notes that are entitled to vote or take other action under the 2018B Indenture. However, the record date may not be earlier than 30 days before the date of the first solicitation of holders to vote on or take such action and not later than the date such solicitation is completed. If we set a record date for a vote or other action to be taken by holders of the 5.75% Unsecured Notes, that vote or action may be taken only by persons who are holders of the 5.75% Unsecured Notes on the record date and must be taken within eleven months following the record date.
 
 Defeasance
 
 The following provisions are applicable to the 5.75% Unsecured Notes. "Defeasance" means that, by depositing with a trustee an amount of cash and/or government securities sufficient to pay all principal and interest, if any, on the 5.75% Unsecured Notes when due and satisfying any additional conditions noted below, we are deemed to have been discharged from our obligations under the 5.75% Unsecured Notes. In the event of a "covenant defeasance," upon depositing such funds and satisfying similar conditions discussed below we would be released from certain covenants under the indenture relating to the 5.75% Unsecured Notes.
 
 Covenant Defeasance
 
 Under current U.S. federal income tax law and the indenture, we can make the deposit described below and be released from some of the restrictive covenants in the indenture under which the 5.75% Unsecured Notes were issued. This is called "covenant defeasance." In that event, the Noteholders would lose the protection of those restrictive covenants but would gain the protection of having money and government securities set aside in trust to repay the Noteholders 5.75% Unsecured Notes. In order to achieve covenant defeasance, the following must occur:
 
 •Since the 5.75% Unsecured Notes are denominated in U.S. dollars, we must deposit in trust for the benefit of all holders of the 5.75% Unsecured Notes a combination of cash and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the 5.75% Unsecured Notes on their various due dates; 
 •We must deliver to the trustee a legal opinion of our counsel confirming that, under current U.S. federal income tax law, we may make the above deposit without causing the Noteholders to be taxed on the 5.75% Unsecured Notes any differently than if we did not make the deposit; 
 •We must deliver to the trustee a legal opinion of our counsel stating that the above deposit does not require registration by us under the 1940 Act, and a legal opinion and officers' certificate stating that all conditions precedent to covenant defeasance have been complied with; 
 •Defeasance must not result in a breach or violation of, or result in a default under, the indenture or any of our other material agreements or instruments; and 
 •No default or Event of Default with respect to the 5.75% Unsecured Notes shall have occurred and be continuing and no defaults or events of default related to bankruptcy, insolvency or reorganization shall occur during the next 90 days. 
 If we accomplish covenant defeasance, the Noteholders can still look to us for repayment of the 5.75% Unsecured Notes if there were a shortfall in the trust deposit or the trustee is prevented from making payment. In fact, if one of the remaining Events of Default occurred (such as our bankruptcy) and the 5.75% Unsecured Notes became immediately due and payable, there might be a shortfall. Depending on the event causing the default, the Noteholders may not be able to obtain payment of the shortfall.
 
 Full Defeasance
 
 If there is a change in U.S. federal income tax law, as described below, we can legally release ourselves from all payment and other obligations on the 5.75% Unsecured Notes (called "full defeasance") if we put in place the following other arrangements for the Noteholders to be repaid:
 
 
  
 
 
 •Since the 5.75% Unsecured Notes are denominated in U.S. dollars, we must deposit in trust for the benefit of all holders of the 5.75% Unsecured Notes a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the 5.75% Unsecured Notes on their various due dates; 
 •We must deliver to the trustee a legal opinion confirming that there has been a change in current U.S. federal tax law or an Internal Revenue Service ("IRS") ruling that allows us to make the above deposit without causing the Noteholders to be taxed on the 5.75% Unsecured Notes any differently than if we did not make the deposit; 
 •We must deliver to the trustee a legal opinion of our counsel stating that the above deposit does not require registration by us under the 1940 Act, and a legal opinion and officers' certificate stating that all conditions precedent to defeasance have been complied with; 
 •Defeasance must not result in a breach or violation of, or constitute a default under, the indenture or any of our other material agreements or instruments; and 
 •No default or Event of Default with respect to the 5.75% Unsecured Notes shall have occurred and be continuing and no defaults or events of default related to bankruptcy, insolvency or reorganization shall occur during the next 90 days. 
 If we ever did accomplish full defeasance, as described above, the Noteholders would have to rely solely on the trust deposit for repayment of the 5.75% Unsecured Notes. The Noteholders could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent.
