 Exhibit 4.31 

DESCRIPTION OF SECURITIES 

As of December 31, 2019, Crescent Capital BDC, Inc. (“Crescent Capital,” the “Company,” “we,”
“us” or “our”) had one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended, our common stock. In this exhibit, references to “Crescent Capital,” “we,”
“us” and “our” refer only to Crescent Capital and not any of its subsidiaries. Capitalized terms used but not defined herein shall have the meaning ascribed to them in the Annual Report on Form
10-K to which this Description of Securities is attached as an exhibit. 
 a)    Common
Stock, $0.001 par value per share 
 The statements made under this caption include summaries of certain provisions contained in our
Articles of Amendment and Restatement, as amended, (the “Charter”) and Amended and Restated Bylaws, as amended, (the “Bylaws”) each of which is filed as an exhibit to our Annual Report on Form
10-K of which this Exhibit 4.31 is a part. This summary does not purport to be complete and is qualified in its entirety by reference to our Charter and Bylaws. We encourage you to read our Charter, Bylaws,
and the applicable provisions of the Maryland General Corporation Law (“MGCL”). 
 Our authorized stock consists of 200,010,000
shares of stock, par value $0.001 per share, 200,000,000 of which are currently classified as common stock and 10,000 of which are currently classified as preferred stock. There are no outstanding options or warrants to purchase our stock. No stock
has been authorized for issuance under any equity compensation plans. Under Maryland law, our stockholders generally are not personally liable for our indebtedness or obligations. 

Under the charter, our board of directors (the “Board”) is authorized to classify any unissued shares of stock and reclassify any
previously classified but unissued shares of stock into one or more classes or series of stock and authorize the issuance of shares of stock without obtaining stockholder approval. As permitted by the MGCL, the Charter provides that a majority of
the entire Board, without any action by our stockholders, may amend the Charter from time to time to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that has authority to issue.

 Common Stock 
 All shares of Common Stock have
equal rights as to earnings, assets, dividends and voting and, when they are issued, will be duly authorized, validly issued, fully paid and nonassessable. Distributions may be paid to the holders of Common Stock if, as and when authorized by the
Board and declared by us out of funds legally available therefor. Shares of Common Stock have no preemptive, exchange, conversion or redemption rights and are freely transferable, except as otherwise provided in the Charter or where their transfer
is restricted by federal and state securities laws or by contract. The Charter provides that during the period beginning with the date the Company reincorporated as a Maryland corporation (the “Reincorporation”) and ending 365 days after
the date listing of the Common Stock on a national securities exchange (the “Listing”), any transfer (whether by sale, gift, merger, operation of law or otherwise), exchange, assignment, pledge, hypothecation or other disposition or
encumbrance of any shares of Common Stock acquired by a stockholder attendant to the Reincorporation is prohibited, and therefore not effective, until the later of (a) the date of such transfer or (b) 180 days after the date of the Listing for one-third of the shares of Common Stock acquired by a stockholder in connection with the Reincorporation, 270 days after the date of the Listing for an
additional one-third of the shares of Common Stock acquired by a stockholder in connection with the Reincorporation and 365 days after the date of the Listing for the
remaining one-third of the shares of Common Stock acquired by a stockholder in the Reincorporation Merger, unless the Board provides prior written consent permitting an earlier effective date and the
transfer, exchange, assignment, pledge, hypothecation or other disposition or encumbrance is made in accordance with applicable securities and other laws. The Board may impose certain conditions in connection with granting its consent to an earlier
effective date and any such consent shall be granted in the sole discretion of the Board. Any purported transfer, exchange, assignment, pledge, hypothecation or other disposition or encumbrance of any shares of Common Stock effected on an earlier
effective date in violation of the Charter will have no force or effect, and will not register or permit registration of (and will direct its transfer agent, if any, not to register or permit registration of) any such purported transfer, exchange,
assignment, pledge, hypothecation or other disposition or encumbrance on its books and records until the applicable effective date. 

 In the event of our liquidation, dissolution or winding up, each share of Common Stock would be entitled to
share ratably in all of our assets that are legally available for distribution after pays off all indebtedness and other liabilities and subject to any preferential rights of holders of our preferred stock, if any preferred stock is outstanding at
such time. 
 Except as may otherwise be specified in the Charter, each share of 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 Common Stock will possess exclusive voting power. There is no cumulative voting in the election of our
directors, which means that holders of a majority of the outstanding shares of Common Stock can elect all of our directors. 
 Limitation on Liability of
Directors and Officers; Indemnification and Advance of Expenses 
 Maryland law permits a Maryland corporation to include in its charter a provision
limiting the liability of its directors and officers to the corporation and its stockholders for money damages except for liability resulting from (a) actual receipt of an improper benefit or profit in money, property or services or
(b) active and deliberate dishonesty established by a final adjudication as being material to the cause of action. The Charter contains such a provision, which eliminates directors’ and officers’ liability to the maximum extent
permitted by Maryland law, subject to the requirements of the Investment Company Act. 
 The Charter requires , to the maximum extent permitted by Maryland
law and subject to the requirements of the Investment Company Act, to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition
of a proceeding to any present or former director or officer or any individual who, while a director or officer and at our request, serves or has served another corporation, real estate investment trust, limited liability company, partnership, joint
venture, trust, employee benefit plan or other enterprise as a director, officer, trustee, member, manager or partner, in each case who is made or threatened to be made a party to, or witness in, the proceeding by reason of his or her service in
that capacity. The Charter also permits us to indemnify and advance expenses to any person who served a predecessor of us in any of the capacities described above and any of our employees or agents or any employees or agents of our predecessor. In
accordance with the Investment Company Act, we will not indemnify any person for any liability to which such person would be subject by reason of such person’s willful misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his or her office. 
 In addition to the indemnification provided for in the Charter, we have entered into indemnification
agreements with each of our current directors and certain of our officers and with members of our investment adviser’s investment committee and we intend to enter into indemnification agreements with each of our future directors, members of our
investment committee and certain of our officers. The indemnification agreements attempt to provide these directors, officers and other persons the maximum indemnification permitted under Maryland law and the Investment Company Act. The agreements
provide, among other things, for the advancement of expenses and indemnification for liabilities that such person may incur by reason of his or her status as a present or former director or officer or member of our investment adviser’s
investment committee in any action or proceeding arising out of the performance of such person’s services as a present or former director or officer or member of our investment adviser’s investment committee. 

Maryland law requires a corporation (unless its charter provides otherwise, which the Charter does not) to indemnify a director or officer who has been
successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made or threatened to be made a party by reason of his or her service in that capacity. Maryland law permits a corporation to indemnify its present and
former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or are threatened to be made a party by
reason of their service in those or other capacities unless it is established that (a) the act or omission of the director or officer was material to the matter giving rise to the proceeding and (i) was committed in bad faith or
(ii) was the result of active and deliberate dishonesty, (b) the director or officer actually received an improper personal benefit in money, property or services or (c) in the case of any criminal proceeding, the director or officer
had reasonable cause to believe that the act or omission was unlawful. However, under Maryland law, a Maryland corporation may not indemnify for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on
the basis that a personal benefit was improperly received, unless in either case a court orders indemnification, and then only for expenses. In addition, Maryland law permits a corporation to advance reasonable expenses to a director or officer upon
the corporation’s receipt of (x) a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation and (y) a written
undertaking by him or her or on his or her behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the standard of conduct was not met.

 Provisions of the Maryland General Corporation Law and the Charter and Bylaws 

The MGCL and the Charter and Bylaws contain provisions that could make it more difficult for a potential acquiror to acquire Crescent Capital by means of a
tender offer, proxy contest or otherwise. These provisions are expected to discourage certain coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of to negotiate first with the Board. believes
that the benefits of these provisions outweigh the potential disadvantages of discouraging any such acquisition proposals because, among other things, the negotiation of such proposals may improve their terms. 

Classified Board of Directors 
 The Board is
divided into three classes of directors serving staggered three-year terms, with the term of office of only one of the three classes expiring each year. A classified board may render a change in control of or removal of our incumbent management more
difficult. believes, however, that the longer time required to elect a majority of a classified board of directors helps to ensure the continuity and stability of our management and policies. 

Election of Directors 
 The Bylaws provide that the
affirmative vote of a majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present shall be sufficient to elect each director; provided, that if the number of nominees for director exceeds the number of
directors to be elected, directors will be elected by a plurality of votes cast. 
 Number of Directors; Vacancies; Removal 

The Charter provides that the number of directors will be set only by the Board in accordance with the Bylaws. The Bylaws provide that a majority of our entire
board of directors may at any time increase or decrease the number of directors. However, unless the Bylaws are amended, the number of directors may never be less than four or more than 15. The Charter sets forth our election to be subject to the
provision of Subtitle 8 of Title 3 of the MGCL regarding the filling of vacancies on the Board. Accordingly, except as may be provided by the Board in setting the terms of any class or series of preferred stock, any and all vacancies on the Board
may be filled only by the affirmative vote of a majority of the remaining directors in office, even if the remaining directors do not constitute a quorum, and any director elected to fill a vacancy will serve for the remainder of the full term of
the class in which the vacancy occurred and until a successor is elected and qualifies, subject to any applicable requirements of the Investment Company Act. 

The Charter provides that a director may be removed only for cause, as defined in the Charter, and then only by the affirmative vote of stockholders entitled
to cast at least two-thirds of the votes entitled to be cast generally in the election of directors. 

Action by Stockholders 
 Under the MGCL,
stockholder action can be taken only at an annual or special meeting of stockholders or by unanimous written or electronically transmitted consent instead of a meeting. These provisions, combined with the requirements of the Bylaws regarding the
calling of a stockholder-requested special meeting of stockholders discussed below, may have the effect of delaying consideration of a stockholder proposal until the next annual meeting.

 Advance Notice Provisions for Stockholder Nominations and Stockholder Proposals 

The Bylaws provide that with respect to an annual meeting of stockholders, nominations of individuals for election to the Board and the proposal of business to
be considered by stockholders may be made only (a) pursuant to our notice of the meeting, (b) by or at the direction of the Board or (c) by a stockholder who is a stockholder of record at the record date set by the Board for the
purpose of determining stockholders entitled to vote at the meeting, at the time of giving the advance notice required by the Bylaws and at the time of the meeting (and any adjournment or postponement thereof), is entitled to vote at the meeting in
the election of each individual so nominated or on any such other business and has complied with the advance notice procedures of the Bylaws. With respect to special meetings of stockholders, only the business specified in our notice of the meeting
may be brought before the meeting. Nominations of individuals for election to the Board at a special meeting may be made only (a) by or at the direction of the Board or (b) provided that the special meeting has been called in accordance
with the Bylaws for the purpose of electing directors, by a stockholder who is a stockholder of record at the record date set by the Board for the purpose of determining stockholders entitled to vote at the meeting, at the time of giving the advance
notice required by the Bylaws and at the time of the meeting (and any adjournment or postponement thereof), who is entitled to vote at the meeting in the election of each individual so nominated and who has complied with the advance notice
provisions of the Bylaws. 
 The purpose of requiring stockholders to give advance notice of nominations and other business is to afford the Board 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 the Board, to inform stockholders and make recommendations about
such qualifications or business, as well as to provide a more orderly procedure for conducting meetings of stockholders. Although the Bylaws do not give the Board 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. 

Calling of Special Meetings of Stockholders 
 The
Bylaws provide that special meetings of stockholders may be called by the Board and certain of our officers. Additionally, the Bylaws provide that, subject to the satisfaction of certain procedural and informational requirements by the stockholders
requesting the meeting, a special meeting of stockholders must be called by the secretary of the corporation to act on any matter that may properly be considered at a meeting of stockholders upon the written request of stockholders entitled to cast
not less than a majority of all the votes entitled to be cast on such matter at such meeting. 
 Approval of Extraordinary Corporate Action; Amendment of
the Charter and Bylaws 
 Under Maryland law, a Maryland corporation generally cannot dissolve, amend its charter, merge, convert, sell all or
substantially all of its assets, engage in a share exchange or engage in similar transactions outside the ordinary course of business, unless approved by the affirmative vote of stockholders entitled to cast at
least two-thirds of the votes entitled to be cast on the matter. However, a Maryland corporation may provide in its charter for approval of these matters by a lesser percentage, but not less than a
majority of all of the votes entitled to be cast on the matter. The Charter generally provides for approval of charter amendments and extraordinary transactions by the stockholders entitled to cast at least a majority of the votes entitled to be
cast on the matter. The Charter also provides that certain charter amendments and any proposal for our conversion, whether by merger or otherwise, from a closed-end company to an open-end company or any proposal for our liquidation or dissolution require the approval of the stockholders entitled to cast at least 80% of the votes entitled to be cast on such matter. However, if
such amendment or proposal is approved by at least two-thirds of our continuing directors (as defined below) (in addition to approval by the Board), such amendment or proposal may be approved by a
majority of the votes entitled to be cast on the matter. The “continuing directors” are defined in the Charter as our current directors as well as those directors whose nomination for election by the stockholders or whose election by the
directors to fill vacancies is approved by a majority of the continuing directors then on the board of directors. 

  
 4 

 The Bylaws provide that the board of directors will have the power to adopt, alter or repeal any provision
of the Bylaws and to make new bylaws. The Bylaws also provide that the stockholders will have the power, at any annual or special meeting of the stockholders, subject to the requirements in the Bylaws regarding the advance notice of stockholder
proposals or the calling of a stockholder-requested special meeting of stockholders, as the case may be, to alter or repeal any provision of the Bylaws and to adopt new bylaws if any such alteration, repeal or adoption is approved by the affirmative
vote of a majority of all votes entitled to be cast on the matter and is otherwise permitted by applicable law, except that the stockholders will not have the power to alter or repeal or adopt any provision inconsistent with the amendment provisions
of the Bylaws without the approval of the Board. 
 No Appraisal Rights 

Except with respect to appraisal rights arising in connection with the Control Share Acquisition Act discussed below, as permitted by the MGCL, the Charter
provides that stockholders will not be entitled to exercise appraisal rights unless the Board determines that such rights will apply, with respect to all or any classes or series of stock, to one or more transactions occurring after the date of such
determination in connection with which stockholders would otherwise be entitled to exercise appraisal rights. 
 Control Share Acquisitions

 The Control Share Acquisition Act provides that control shares of a Maryland corporation acquired in a control share acquisition have no voting
rights except to the extent approved by a vote of stockholders entitled to cast at least two-thirds of the votes entitled to be cast on the matter. Shares owned by the acquiror, by officers or by
employees who are directors of the corporation are excluded from shares entitled to vote on the matter. Control shares are voting shares of stock that, if aggregated with all other shares of stock owned by the acquiror or in respect of which the
acquiror is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiror to exercise voting power in electing directors within one of the following ranges of voting power: 

 

	 	•	 	 one-tenth or more but less than one-third;

  

	 	•	 	 one-third or more but less than a majority; or 

 

	 	•	 	 a majority or more of all voting power. 

The requisite stockholder approval must be obtained each time an acquiror crosses one of the thresholds of voting power set forth above. Control shares do not
include shares the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval. A control share acquisition means the acquisition of issued and outstanding control shares, subject to certain exceptions.

 A person who has made or proposes to make a control share acquisition may compel the board of directors of the corporation to call a special meeting of
stockholders to be held within 50 days of demand to consider the voting rights of the shares. The right to compel the calling of a special meeting is subject to the satisfaction of certain conditions, including an undertaking to pay the
expenses of the meeting. If no request for a meeting is made, the corporation may itself present the question at any stockholders meeting. 
 If voting
rights are not approved at the meeting or if the acquiring person does not deliver an acquiring person statement as required by the statute, then the corporation may redeem for fair value any or all of the control shares, except those for which
voting rights have previously been approved. The right of the corporation to redeem control shares is subject to certain conditions and limitations, including, as provided in the Bylaws, compliance with the Investment Company Act, which will
prohibit any such redemption other than in limited circumstances. Fair value is determined, without regard to the absence of voting rights for the control shares, as of the date of any meeting of stockholders at which the voting rights of the shares
are considered and not approved or, if no such meeting is held, as of the date of the last control share acquisition by the acquiror. If voting rights for control shares are approved at a stockholders meeting and the acquiror becomes entitled to
vote a majority of the shares entitled to vote, all other stockholders may exercise appraisal rights. The fair value of the shares as determined for purposes of appraisal rights may not be less than the highest price per share paid by the acquiror
in the control share acquisition. 

  
 5 

 The Control Share Acquisition Act does not apply (a) to shares acquired in a merger, consolidation or
share exchange if the corporation is a party to the transaction or (b) to acquisitions approved or exempted by the charter or bylaws of the corporation. 

The Bylaws contain a provision exempting from the Control Share Acquisition Act any and all acquisitions by any person of our shares of stock and, as a
result, any control shares of will have the same voting rights as all of the other shares of Common Stock. Such provision could be amended or eliminated at any time in the future. However, will amend the Bylaws to be subject to the Control Share
Acquisition Act only if the Board determines that it would be in our best interests and determines (after consultation with the SEC staff) that our being subject to the Control Share Acquisition Act does not conflict with the Investment Company Act.

 Business Combinations 
 Under Maryland law,
“business combinations” between a Maryland corporation and an interested stockholder or an affiliate of an interested stockholder are prohibited for five years after the most recent date on which the interested stockholder becomes an
interested stockholder. These business combinations include a merger, consolidation, share exchange or, in circumstances specified in the statute, an asset transfer or issuance or reclassification of equity securities. An interested stockholder is
defined as: 
  

	 	•	 	 any person who, directly or indirectly, beneficially owns 10% or more of the voting power of the
corporation’s outstanding voting stock; or 

  

	 	•	 	 an affiliate or associate of the corporation who, at any time within
the two-year period prior to the date in question, was the beneficial owner, directly or indirectly, of 10% or more of the voting power of the then outstanding stock of the corporation.

 A person is not an interested stockholder under this statute if the board of directors approved in advance the transaction by which
such person otherwise would have become an interested stockholder. However, in approving a transaction, the board of directors may provide that its approval is subject to compliance, at or after the time of approval, with any terms and conditions
determined by the board. 
 After the five-year prohibition, any business combination between the corporation and an interested stockholder generally must
be recommended by the board of directors of the corporation and approved by the affirmative vote of at least: 
  

	 	•	 	 80% of the votes entitled to be cast by holders of outstanding shares of voting stock of the corporation; and

  

	 	•	 	 two-thirds of the votes entitled to be cast by holders of voting
stock of the corporation other than shares held by the interested stockholder with whom or with whose affiliate the business combination is to be effected or held by an affiliate or associate of the interested stockholder. 

These super-majority vote requirements do not apply if the corporation’s common stockholders receive a minimum price, as defined under Maryland law, for
their shares in the form of cash or other consideration in the same form as previously paid by the interested stockholder for its shares. 
 The statute
permits various exemptions from its provisions, including business combinations that are exempted by the board of directors before the time that the interested stockholder becomes an interested stockholder. The Board has adopted a resolution that
any business combination between us and any other person is exempted from the provisions of the Business Combination Act, provided that the business combination is first approved by the Board, including a majority of the independent directors. This
resolution, however, may be altered or repealed in whole or in part at any time. If this resolution is repealed or the Board does not otherwise approve a business combination, the statute may discourage others from trying to acquire control of and
increase the difficulty of consummating any offer.

 Conflict with the Investment Company Act 

The Bylaws provide that, if and to the extent that any provision of the MGCL, including the Control Share Acquisition Act (if we amend the Bylaws to be subject
to such act) and the Business Combination Act, or any provision of the Charter or Bylaws conflicts with any provision of the Investment Company Act, the applicable provision of the Investment Company Act will control. 

Exclusive Forum 
 The Charter provides that, unless
consents in writing to the selection of an alternative forum, the Circuit Court for Baltimore City, Maryland, or, if that Court does not have jurisdiction, the United States District Court for the District of Maryland, Baltimore Division, will be
the sole and exclusive forum for: (i) any derivative action or proceeding brought on our behalf, (ii) any Internal Corporate Claim, as such term is defined in Section 1-101(p) of the
MGCL, including, without limitation, (a) any action asserting a claim of breach of any duty owed by any of our directors or officers or other employees to or to our stockholders or (b) any action asserting a claim against or any of our
directors or officers or other employees arising pursuant to any provision of the MGCL or the Charter or Bylaws, or (iii) any action asserting a claim against or any of our directors or officers or other employees that is governed by the
internal affairs doctrine. Any person or entity purchasing or otherwise acquiring or holding any interest in our stock will be deemed to have notice of and to have consented and waived any objection to this exclusive forum provision of the Charter,
as the same may be amended from time to time.

14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of
a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Securities, the Company shall comply with those securities laws and

consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and its subsidiaries taken as a whole to any “person” or “group” (as those terms are used in
Section 13(d)(3) of the Exchange Act) other than to the Company or one of its subsidiaries;

such employee shall not be a member of a “group” (as that term is used in

such other Person is converted into or exchanged for cash, securities or other property, other than any such transaction where the Company’s Voting Stock outstanding immediately prior to such transaction constitutes, or is converted into or
exchanged for, Voting Stock representing at least a majority of the voting power of the Voting Stock of the surviving Person immediately after giving effect to such transaction;

by each of the Rating Agencies on any day during the Trigger Period; provided that a Change of Control Triggering Event will not be deemed to have occurred in respect of a particular Change of Control if each Rating Agency making the
reduction in rating does not publicly announce or confirm or inform the Trustee at the Company’s request that the reduction was the result, in whole or 

  
 7 

 
in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the Change of Control.

which such member was named as a nominee for election as a director).

better by Moody’s (or its equivalent under any successor rating category of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating category of S&P), and

primary obligor and not merely as a surety, to each Securityholder and to the Trustee and its successors and assigns (i) the full and punctual payment when due, whether at fixed maturity, by acceleration, by redemption or otherwise, of all
obligations of the Company under the Indenture (including obligations to the Trustee) and the Securities, whether for payment of principal of, or interest on, in respect of the Securities and all other monetary obligations of the Company under the
Indenture and the Securities and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Company whether for fees, expenses, indemnification or otherwise under this Indenture and the Securities

performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Securityholder or the Trustee to any security held for payment of the Guaranteed Obligations. 

(e) Except as expressly set forth in Section 11.02 of the Base Indenture or Sections 3.02 and 3.06 hereof, the obligations of the

any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of
the Guarantor and each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Securityholder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the
Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or
thing which may or might in any manner or to any extent vary the risk of the Guarantor and each Subsidiary Guarantor or would otherwise operate as a discharge of the Guarantor and each Subsidiary Guarantor as a matter of law or equity.

any time payment, or any part thereof, of principal of, or interest on, any Guaranteed Obligation is rescinded or must otherwise be restored by any Securityholder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise. 

(g) In furtherance of the foregoing and not in limitation of any other right which any Securityholder or the Trustee has at law or in
equity against the Guarantor and each Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of, or interest on, on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by
acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each of the Guarantor and each Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay,
or 

  
 11 

 cause to be paid, in cash, to the Securityholders or the Trustee an amount equal to the sum of

between it, on the one hand, and the Securityholders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 6 of the Base Indenture for the purposes of the
guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed
Obligations as provided in Article 6 of the Base Indenture, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor and each Subsidiary Guarantor for the purposes of this
Section 3.01.

such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of the Indenture. 

Section 3.02 Limitation on Liability. 

Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations
guaranteed hereunder by the Guarantor and each Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering the Indenture, as it relates to the Guarantor and each Subsidiary Guarantor, voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 

Section 3.03 Successors and Assigns. 

This Article 3 shall be binding upon each of the Guarantor and each Subsidiary Guarantor and its respective successors and assigns and
shall inure to the benefit of the successors and assigns of the Trustee and the Securityholders and, in the event of any transfer or assignment of rights by any Securityholder or 

  
 12 

 
the Trustee, the rights and privileges conferred upon that party in the Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to
the terms and conditions of the Indenture. 
 Section 3.04 No Waiver. 

Neither a failure nor a delay on the part of either the Trustee or the Securityholders in exercising any right, power or privilege under this Article 3
shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Securityholders herein expressly
specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 3 at law, in equity, by statute or otherwise. 

Section 3.05 Modification. 

No modification, amendment or waiver of any provision of this Article 3, nor the consent to any departure by the Guarantor or a
Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No
notice to or demand on the Guarantor or a Subsidiary Guarantor in any case shall entitle the Guarantor or a Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances. 

Section 3.06 Release of the Guarantor or Subsidiary Guarantor. 

(a) The Guarantor or a Subsidiary Guarantor, as the case may be, shall be released from its obligations under this Article 3 (other than

(vii) any other Event of Default provided for with respect to the Securities of such series in accordance with
Section 2.01.” 
 (b) Section 6.01(b) of the Base Indenture is hereby deleted in its entirety and replaced with the
following, solely for purposes of the Securities to be issued hereunder: 
 “If an Event of Default described in clauses (a)(i)
or (a)(ii) of this Section 6.01 with respect to the Securities of any series then Outstanding hereunder occurs and is continuing, then, unless the principal of the Securities of such series shall have already become due and payable, either the
Trustee or the holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding, by notice in writing to the Company (and to the Trustee if given by such Securityholders), may declare the principal of all
the Securities of such series and interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, notwithstanding anything contained in this Indenture
or in the Securities of such series or established with respect to such series pursuant to Section 2.01 to the contrary. 
 If an
Event of Default described in clauses (a)(iii), (a)(iv) or (a)(vii) of this Section 6.01 with respect to Securities of one or more series then Outstanding hereunder occurs and is continuing, then, except with respect to any such affected series
for which the principal of all the Securities thereof shall have already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Securities of all affected series then Outstanding (all such
series voting together as a single class), by notice in writing to the Company (and to the Trustee if given by such Securityholders), may declare the principal of all the Securities then Outstanding of such series and interest accrued thereon, if
any, to be due and payable immediately, and upon such declaration the same shall become immediately due and payable. 
 If an Event of
Default described in clauses (a)(v) or (a)(vi) of this Section 6.01 with respect to Securities of one or more series then Outstanding hereunder occurs and is continuing, the principal (or such specified amount) of and accrued and unpaid
interest, if any, on all Outstanding Securities will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holder of Outstanding Securities. At any time after a declaration of acceleration
with respect to Securities of any series has been made, and before a judgment or decree for payment of the money due has been obtained by the Trustee, the holders of a majority in principal amount of the Outstanding

  
 16 

 
Securities of that series may rescind and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and
interest, if any, with respect to Securities of that series, have been cured or waived as provided in this Indenture.” 
 (c)
Section 6.01(c) of the Base Indenture is hereby deleted in its entirety and replaced with the following, solely for purposes of the Securities to be issued hereunder: 

“At any time after the principal of the Securities of any series shall have been declared due and payable as provided in
Section 6.01(b), and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the holders of a majority in aggregate principal amount of the Securities of such series then
Outstanding (in the case of an Event of Default described in clauses (a)(i) or (a)(ii) of this Section 6.01, each such affected series voting as a separate class, and in the case of an Event of Default described in clauses (a)(iii), (a)(iv),
(a)(v), (a)(vi) or (a)(vii) of this Section 6.01, all such affected series voting together as a single class), by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: (i) the
Company has paid or deposited with the Trustee a sum sufficient to pay all matured installments of interest upon all the Securities of such series and the principal of (and premium, if any, on) any and all Securities of such series that shall have
become due otherwise than by acceleration (with interest upon such principal and premium, if any, and, to the extent that such payment is enforceable under applicable law, upon overdue installments of interest, applied to the Securities of each such
series at the rate per annum expressed in the Securities of each such series, respectively, to the date of such payment or deposit) and the amount payable to the Trustee under Section 7.06, and (ii) any and all Events of Default under the
Indenture with respect to such series, other than the nonpayment of principal on Securities of that series that shall not have become due by their terms, shall have been remedied or waived as provided in Section 6.06. 

No such rescission and annulment shall extend to or shall affect any subsequent default or impair any right consequent thereon.”

 (d) Section 6.04 of the Base Indenture is hereby deleted in its entirety and replaced with the following, solely for purposes
of the Securities to be issued hereunder: 
 “No holder of any Security of any series shall have any right by virtue or by
availing itself of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture or for the appointment of a receiver or trustee, or for any other remedy hereunder,
unless: (a) such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof with respect to the Securities of such series specifying such Event of Default, as hereinbefore provided;
(b) the 

  
 17 

 
holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such series (in the case of an Event of Default described in Section 6.01(a)(i) or
Section 6.01(a)(ii), each such series voting as a separate class, and in the case of an Event of Default described in Section 6.01(a)(iii), Section 6.01(a)(iv), Section 6.01(a)(v), Section 6.01(a)(vi) or
Section 6.01(a)(vii), all affected series voting together as a single class) or shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as trustee hereunder; (c) such holder or holders
shall have offered indemnity satisfactory to the Trustee as it may require against the costs, expenses and liabilities to be incurred therein or thereby; (d) the Trustee for 60 days after its receipt of such notice, request and offer of
indemnity, shall have failed to institute any such action, suit or proceeding; and (e) during such 60 day period, the holders of a majority in principal amount of the Securities of such series (voting as provided in clause (b) above) do
not give the Trustee conflicting directions with the request. 
 Notwithstanding anything contained herein to the contrary, any other
provisions of this Indenture, the right of any holder of any Security to receive payment of the principal of (and premium, if any) and interest on such Security, as therein provided, on or after the respective due dates expressed in such Security
(or in the case of redemption, on the redemption date), or to institute suit for the enforcement of any such payment on or after such respective dates or redemption date, is absolute and unconditional and shall not be impaired or affected without
the consent of such holder and by accepting a Security hereunder it is expressly understood, intended and covenanted by the taker and holder of every Security of such series with every other such taker and holder and the Trustee, that no one or more
holders of Securities of such series shall have any right in any manner whatsoever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of the holders of any other of such Securities, or to obtain or
seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Securities of such series. For
the protection and enforcement of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.”

4.125% Senior Notes due 2028 

FREEPORT-MCMORAN INC., a Delaware corporation (the “Company”, which term includes any successor corporation under the
Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or its registered assigns, the principal sum of [—] dollars ($[—]) (which aggregate principal amount may from time to time be increased
or decreased to such other aggregate principal amounts by adjustments made on the Schedule of Increases or Decreases in Global Security attached hereto) on March 1, 2028 and to pay interest on said principal sum from March 4, 2020 or from
the most recent interest payment date (each such date, an “Interest Payment Date”) on which interest has been paid or duly provided for semiannually on September 1 and 

  
 A-1 

 March 1 of each year commencing September 1, 2020 at the rate of 4.125% per annum until the
principal hereof shall have become due and payable, and on any overdue principal and premium, if any, and (without duplication and to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of
interest at the same rate per annum. The amount of interest payable on any Interest Payment Date shall be computed on the basis of a 360-day year of twelve 30-day
months. In the event that any date on which interest is payable on this Note is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay). The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture (hereafter defined), be paid to the person in whose name this Note
(or one or more Predecessor Securities, as defined in said Indenture) is registered at the close of business on the regular record date for such interest installment which shall be the August 15 or February 15 preceding such Interest
Payment Date, except that interest payable at maturity shall be paid to the same person to whom principal of the Securities is payable. Any such interest installment that is payable, but is not punctually paid or duly provided for on any Interest
Payment Date (as defined in the Indenture, the “Defaulted Interest”) shall forthwith cease to be payable to the registered holders on such regular record date by virtue of having been such registered holder, and such Defaulted
Interest shall be paid by the Company, at its election, (i) to the person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a special record date for the payment of such Defaulted
Interest, which shall not be more than 15 nor less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment or (ii) in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. The principal of (and premium, if any) and
the interest on this Note shall be payable at the office or agency of the Company maintained for that purpose in any coin or currency of the United States of America which at the time of payment is legal tender for payment of public and private
debts. Notwithstanding the foregoing, so long as the registered holder of this Note is Cede & Co., the payment of the principal of (and premium, if any) and interest on this Note will be made at such place and to such account as may be
designated by DTC. 
 The indebtedness evidenced by this Note is, to the extent provided in the Indenture, senior and unsecured and
will rank in right of payment on parity with all other senior unsecured obligations of the Company. 
 This Note shall not be entitled
to any benefit under the Indenture hereinafter referred to, be valid or become obligatory for any purpose until the Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee.

 The provisions of this Note are continued on the reverse side hereof and such
continued provisions shall for all purposes have the same effect as though fully set forth at this place.

 [REVERSE SIDE OF NOTE] 

FREEPORT-MCMORAN INC. 
 4.125% Senior Notes due 2028

 This Note is one of a duly authorized series of Securities (referred to in the Base Indenture (hereafter defined)), of the
Company (herein sometimes referred to as the “Notes”), all such Securities issued or to be issued in one or more series under and pursuant to an indenture (the “Base Indenture”) dated as of August 15, 2019,
between the Company and U.S. Bank National Association, as Trustee (the “Trustee”), as supplemented in the case of the Notes by the Third Supplemental Indenture dated as of March 4, 2020, among the Company, the Guarantor and
the Trustee (the “Third Supplemental Indenture,” together with the Base Indenture, the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the
rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, the Guarantor and the holders of the Notes. The initial aggregate principal amount of the Notes is $700,000,000. There is no limit upon the
aggregate principal amount of Notes of this series that may be authenticated and delivered under the Indenture. The Company may, from time to time, without notice to or the consent of the Holders hereof, create and issue additional Notes of this
series ranking equally and ratably with the Notes in all respects (other than the issue price, the date of the issuance, the payment of interest accruing prior to the issue date of such additional Notes, the first payment of interest following the
issue date of such additional Notes and, in some cases, the first payment of interest following the issue date of such additional Notes). Any such additional Notes shall be consolidated and form a single series with the Notes initially issued,
including for purposes of voting and redemptions; provided that if the additional Notes are not fungible with the Notes of this series initially issued for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP
number. 
 The Notes will be redeemable, at the option of the Company, at any time and from time to time, in whole or in part. The
Notes shall be redeemable at the redemption price (the “Redemption Price”), to be calculated by the Company, as follows: 

(A) If the redemption date is prior to March 1, 2023, the Securities may be redeemed by the Company at a Redemption Price equal to
the greater of (1) 100% of the principal amount of the Securities to be redeemed and (2) the sum of the present values of (a) the Redemption Price of the Securities at March 1, 2023 and (b) the remaining scheduled payments of
interest on the Securities to be redeemed from the date of redemption to March 1, 2023 (not including interest accrued to the date of redemption) discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points, plus, in each case, accrued and unpaid interest on the Securities to be redeemed to
the date of redemption. 
 (B) If the redemption date is prior to March 1, 2023, the Company may redeem in the aggregate up to 35%
of the aggregate principal amount of the Securities issued under the Indenture (including the aggregate principal amount of any additional notes) with the net cash proceeds of one or more Equity Offerings at a Redemption Price equal to 104.125% of
the principal amount of Securities redeemed, plus accrued and unpaid interest thereon, if any, to, but not including, the date of redemption (subject to the rights of holders of the Securities on the relevant record date to receive interest on the
relevant Interest Payment Date falling prior to or on the redemption date); provided that: 
 (1) after giving
effect to any such redemption at least 65% of the aggregate principal amount of the Securities issued under the Indenture (including the aggregate principal amount of any additional notes) remains outstanding immediately after the occurrence of such
redemption; and 
 (2) the redemption occurs within 90 days of the date of, and may be conditioned upon, the closing of
such Equity Offering. 
 (C) If the redemption date is on or after March 1, 2023, the Securities may be redeemed by the Company at
the following Redemption Prices (expressed as a percentage of principal amount) plus accrued and unpaid interest on the Securities to be redeemed to, but not including, the applicable redemption date (subject to the right of holders of record on the
relevant record date to receive interest due on the relevant Interest Payment Date) if on and after the issue date, redeemed during the twelve-month period beginning on September 1 of the years indicated below: 

 

					
	 Year
	  	Redemption
Price	 
	 2023
	  	 	102.063	% 
	 2024
	  	 	101.375	% 
	 2025
	  	 	100.688	% 
	 2026 and thereafter
	  	 	100.000	% 

  
 A-8 

 In case the Company shall desire to exercise such right to redeem all or, as the case
may be, a portion of the Notes, the Company shall (with a copy provided to the Trustee), or shall cause the Trustee to, give notice of such redemption to holders of the Notes to be redeemed by mailing, first class postage prepaid, a notice of such
redemption not less than 30 days and not more than 60 days before the date fixed for redemption to such holders at their last addresses as they shall appear upon the Security Register. Any notice that is mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the registered holder received the notice. In any case, failure duly to give such notice to the holder of any Note designated for redemption in whole or in part, or any defect in the
notice, shall not affect the validity of the proceedings for the redemption of any other Note. 
 Upon the occurrence of a Change of
Control Triggering Event with respect to the Notes, unless the Company has exercised its right to redeem the Notes pursuant to Section 1.03 of the Supplemental Indenture, by giving irrevocable notice to the Trustee in accordance with the
Indenture, each holder of Notes shall have the right to require the Company to purchase all or a portion of such holder’s Notes, at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the
date of purchase, subject to the rights of holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date as provided in, and subject to the terms of, the Indenture. 

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Securities of all of the series at the time Outstanding affected thereby (all such series voting together as a single class), as defined in the Indenture, to execute supplemental indentures for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of the Base Indenture or of any supplemental indenture or of modifying in any manner not covered by Section 9.01 of the Base Indenture the rights of the holders of
the Notes; provided, however, that no such supplemental indenture shall, without the consent of the holders of each Note then Outstanding and affected thereby, (i) extend the fixed maturity of any Securities, including the Notes, or reduce the
principal amount thereof, or reduce the rate or extend the time for payment of interest thereon, or reduce any premium payable upon the redemption thereof, (ii) release the Guarantor or any Subsidiary Guarantor from any of their respective
obligations under their respective guarantees or the 

  
 A-9 

 Indenture other than in accordance with the terms of the Indenture, or (iii) reduce the aforesaid
percentage of Securities, the holders of which are required to consent to any such supplemental indenture. The Indenture also contains provisions permitting the holders of a majority in aggregate principal amount of the Securities of all series at
the time Outstanding affected thereby (all such series voting together as a single class except with respect to a default in the payment of the principal of or premium, if any, or interest on any Securities, including the Notes, in which case, each
such affected series voting as a separate class), on behalf of the holders of all of the Securities of such series, to waive any past default in the performance of any of the covenants contained in the Base Indenture or established pursuant to the
Base Indenture with respect to such series and its consequences, except a default in the payment of the principal of, or premium, if any, or interest on, any of the Securities of any such series as and when the same shall become due by the terms of
such Securities otherwise than by acceleration (unless such default has been cured and a sum sufficient to pay all matured installments of interest and principal and any premium has been deposited with the Trustee in accordance with the Indenture).
Except as provided in the Indenture, any such action taken by the registered holder of this Note shall be conclusive and binding upon such holder and upon all future holders and owners of this Note, and of any Security issued in exchange therefor,
on registration of transfer thereof or in place thereof, irrespective of whether or not any notation in regard thereto is made upon this Note. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the time and place and at the rate and in the money herein prescribed. 

The Company is subject to certain covenants contained in the Indenture with respect to, and for the benefit of the holders of, the
Notes. The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with the covenants contained in the Indenture or with respect to reports or other certificates filed under the
Indenture; provided, however, that nothing herein shall relieve the Trustee of its obligations under Article 7 of the Indenture. If an Event of Default as defined in the Indenture with respect to the Notes shall occur and be
continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. 

As provided in and subject to the provisions of the Indenture, the holder of this Note shall not have the right to institute any suit,
action or proceeding in equity or at law upon or under or with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such holder shall have previously given the Trustee written notice of
a continuing Event of Default with respect to the Notes, the holders of not less than 25% in principal amount of the Outstanding Notes (in the case of an Event of Default
