**DESCRIPTION OF REGISTERED SECURITIES**

*As of December 31, 2019, AB Private Credit Investors Corporation (the “Fund,” “we,” “us,” or “our”) had oneclass of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”): our common stock, par value $0.01 per share (“common stock”).*

*The following description of the Fund’s common stock is based on the relevant provisions of the Maryland General Corporation Law (the“MGCL”), the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the “1940 Act”), the Fund’s charter (the “Charter”) and the Fund’s bylaws (the“Bylaws”). This summary describes the provisions deemed to be material, but is not necessarily complete, and you should refer to the MGCL, 1940 Act and our Charter and Bylaws for a more detailed description of the provisions summarizedbelow.*

*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.*

**Stock**

Our authorized stock consists of 200,000,000 shares, par value $0.01 per share, all of which are classified as common stock. There are no outstanding optionsor 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 debts or obligations. 

Under our Charter, our board of directors (the “Board”) is authorized to classify and reclassify any unissued shares of stock into other classes orseries of stock without obtaining stockholder approval. As permitted by the MGCL, our Charter provides that the Board, without any action by our stockholders, may amend the Charter from time to time to increase or decrease the aggregate number ofshares of stock or the number of shares of stock of any class or series that we have authority to issue. 

***Common Stock***

All shares of our common stock have equal rights as to earnings, assets, voting, and dividends and, when they are issued, will be duly authorized, validlyissued, fully paid and nonassessable. Distributions may be paid to the holders of our common stock if, as and when authorized by our Board and declared by us out of assets legally available therefor. Shares of our common stock have no preemptive,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 stockwould 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 isoutstanding 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, theholders of our common stock will possess exclusive voting power. There is no cumulative voting in the election of directors, which means that holders of a majority of the outstanding shares of common stock can elect all of our directors, and holdersof less than a majority of such shares will be unable to elect any director. 

***Preferred Stock***

Our Charter authorizes our Board to classify and reclassify any unissued shares of stock into other classes or series of stock, including preferred stock. Thecost of any such reclassification would be borne by our existing common stockholders. Prior to the issuance of shares of each class or series, the Board is required by the MGCL and by our Charter to set the terms, preferences, conversion or otherrights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each class or series. Thus, the Board could authorize the issuance of shares of preferred stock withterms and conditions which could have the effect of delaying, deferring or preventing a transaction or a change in control that might involve a premium price for holders of our common stock or otherwise be in their best interest. However, thatissuance of preferred stock must comply with the requirements of the 1940 Act. The 1940 Act requires, among other things, that (1) immediately after issuance 

 
1 

and before any dividend or other distribution is made with respect to our common stock and before any purchase of common stock is made, such preferred stock together with all other seniorsecurities must not exceed an amount equal to 50% of our total assets after deducting the amount of such dividend, distribution or purchase price, as the case may be, and (2) the holders of shares of preferred stock, if any are issued, must beentitled as a class to elect two directors at all times and to elect a majority of the directors if dividends on such preferred stock are in arrears by two full years or more. Certain matters under the 1940 Act require the separate vote of theholders of any issued and outstanding preferred stock. For example, holders of preferred stock would vote separately from the holders of common stock on a proposal to cease operations as a BDC. 

**Limitation on Liability of Directors and Officers; Indemnification and Advance of Expenses**

The MGCL permits a Maryland corporation to include in its charter a provision limiting the liability of its directors and officers to the corporation and itsstockholders 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 judgment as being materialto the cause of action. Our Charter contains such a provision which eliminates directors’ and officers’ liability to the maximum extent permitted by the MGCL, subject to the requirements of the 1940 Act. 

Our Charter authorizes us, to the maximum extent permitted by the MGCL and subject to the requirements of the 1940 Act, to indemnify any present or formerdirector or officer or any individual who, while serving as our director or officer and at our request, serves or has served another corporation, real estate investment trust, limited liability company, partnership, joint venture, trust, employeebenefit plan or other enterprise as a director, officer, partner, trustee, member or manager from and against any claim or liability to which that person may become subject or which that person may incur by reason of his or her service in any suchcapacity and to pay or reimburse their reasonable expenses in advance of final disposition of a proceeding. Our Bylaws obligate us, to the maximum extent permitted by the MGCL and subject to the requirements of the 1940 Act, to indemnify any presentor former director or officer or any individual who, while serving as our 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, partner, trustee, member or manager and who is made, or threatened to be made, a party to the proceeding by reason of his or her service in that capacity from and against any claim orliability to which that person may become subject or which that person may incur by reason of his or her service in any such capacity and to pay or reimburse his or her reasonable expenses in advance of final disposition of a proceeding. The Charterand Bylaws also permit 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 withthe 1940 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 ofhis or her office. 

The MGCL requires a corporation (unless its charter provides otherwise, which our Charter does not) to indemnify a director or officerwho has been successful 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. The MGCL permits a corporation to indemnify its present and former directors andofficers, 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 threatened to be made, a party by reason of their service inthose 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 (1) was committed in bad faith or (2) was the result of active anddeliberate 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 thatthe act or omission was unlawful. However, under the MGCL, 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 wasimproperly received unless, in either case a court orders indemnification, and then only for expenses. In addition, the MGCL permits a corporation to advance reasonable expenses to a director or officer in advance of final disposition of aproceeding upon the corporation’s receipt of (a) 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(b) 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.

We have entered into indemnification agreements with our directors and executive officers. Theindemnification agreements provide our directors and executive officers the maximum indemnification permitted under the MGCL and the 1940 Act. 

**CertainProvisions of the Maryland General Corporation Law and Our Charter and Bylaws**

The MGCL and our Charter and Bylaws contain provisions that could makeit more difficult for a potential acquirer to acquire us by means of a tender offer, proxy contest or otherwise, the material ones of which are discussed below. These provisions are expected to discourage certain coercive takeover practices andinadequate takeover bids and to encourage persons seeking to acquire control of us to negotiate first with our Board. We expect the benefits of these provisions to outweigh the potential disadvantages of discouraging any such acquisition proposalsbecause, among other things, the negotiation of such proposals may improve their terms. 

***Classified Board of Directors***

Our Board is divided into three classes of directors serving staggered three-year terms. The current terms of the first, second and third classes will expirein 2020, 2021, and 2022, respectively, and in each case, those directors will serve until their successors are elected and qualify. Upon expiration of their terms, directors of each class will be elected to serve for three-year terms and until theirsuccessors are duly elected and qualify, and each year one class of directors will be elected by the stockholders (for avoidance of doubt, a director may succeed himself or herself). A classified Board may render a change in control of us or removalof our incumbent management more difficult. We believe, however, that the longer time required to elect a majority of a classified Board will help to ensure the continuity and stability of our management and policies. 

***Election of Directors***

Our Bylaws, as authorizedby our Charter, provide that the affirmative vote of the holders of a plurality of the outstanding shares of stock entitled to vote in the election of directors cast at a meeting of stockholders duly called, and at which a quorum is present, will berequired to elect a director. Pursuant to our Charter our Board may amend the Bylaws to alter the vote required to elect directors. 

***Number ofDirectors; Vacancies; Removal***

Our Charter provides that the number of directors will be set only by the Board in accordance with our Bylaws. OurBylaws provide that a majority of our entire Board may at any time increase or decrease the number of directors. However, unless our Bylaws are amended, the number of directors may never be less than one nor more than nine. Our Charter providesthat, at such time as we have at least three independent directors and our common stock is registered under the Exchange Act, as amended, we elect to be subject to the provision of Subtitle 8 of Title 3 of the MGCL regarding the filling of vacancieson the Board. Accordingly, at such time, 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 theremaining 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 directorship in which the vacancy occurred and until asuccessor is elected and qualifies, subject to any applicable requirements of the 1940 Act. 

Our Charter provides that a director may be removed only forcause, as defined in our Charter, and then only by the affirmative vote of at least two-thirds of the votes entitled to be cast 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 (unless the charter provides for stockholder action by less than unanimous written consent, which our Charter does not) by unanimous written consent in lieu of ameeting. These provisions, combined with the requirements of our 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 untilthe next annual meeting.

***Advance Notice Provisions for Stockholder Nominations and Stockholder Proposals***

Our Bylaws provide that, with respect to an annual meeting of our stockholders, nominations of individuals for election as directors and the proposal ofbusiness to be considered by our 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 both at the time of giving theadvance notice required by our Bylaws and at the time of the meeting, who is entitled to vote at the meeting in the election of each individual so nominated or on any such other business and who has complied with the advance notice procedures of ourBylaws. With respect to special meetings of our stockholders, only the business specified in our notice of the meeting may be brought before the meeting. Nominations of individuals for election as directors at a special meeting at which directorsare to be elected 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 our Bylaws for the purpose of electing directors, by a stockholder who is a stockholderof record both at the time of giving the advance notice required by our Bylaws and at the time of the meeting, who is entitled to vote at the meeting in the election of each individual so nominated and who has complied with the advance noticeprovisions of our Bylaws. 

The purpose of requiring our stockholders to give us advance notice of nominations and other business is to afford the Board ameaningful 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 our stockholders and make recommendationsabout such qualifications or business, as well as to provide a more orderly procedure for conducting meetings of our stockholders. Although our Bylaws do not give the Board any power to disapprove stockholder nominations for the election ofdirectors or proposals recommending certain action, the advance notice and information requirements may have the effect of precluding election contests or the consideration of stockholder proposals if proper procedures are not followed and ofdiscouraging 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 beneficialto the Fund and our stockholders. 

***Calling of Special Meetings of Stockholders***

Our Bylaws provide that special meetings of stockholders may be called by our Board and certain of our officers. Additionally, our Bylaws provide that, subjectto the satisfaction of certain procedural and informational requirements by the stockholders requesting the meeting, a special meeting of stockholders will be called by the secretary of the corporation upon the written request of stockholdersentitled to cast not less than a majority of all the votes entitled to be cast at such meeting. 

***Approval of Extraordinary Corporate Action;Amendment of Charter and Bylaws***

Under the MGCL, a Maryland corporation generally cannot dissolve, amend its charter, merge, sell all orsubstantially 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 leasttwo-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 allof the votes entitled to be cast on the matter. Our 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.Our Charter also provides that certain Charter amendments, any proposal for our conversion, whether by Charter amendment, merger or otherwise, from a closed-end company to anopen-end company and any proposal for our liquidation or dissolution requires the approval of the stockholders entitled to cast at least 80% of the votes entitled to be cast on such matter. However, if suchamendment or proposal is approved by a majority of our continuing directors (in addition to approval by our Board), such amendment or proposal may be approved by a majority of the votes entitled to be cast on such a matter. The “continuingdirectors” are defined in our Charter as (1) our current directors, (2) those directors whose nomination for election by the stockholders or whose election by the directors to fill vacancies is approved by a majority of our currentdirectors then on the Board or (3) any successor directors whose nomination for election by the stockholders or whose election by the directors to fill vacancies is approved by a majority of continuing directors or the successor continuingdirectors then in office. 

Our Charter and Bylaws provide that the Board will have the exclusive power to make, alter, amend or repeal any provision ofour Bylaws.

***No Appraisal Rights***

Except with respect to appraisal rights arising in connection with the Control Share Act discussed below, as permitted by the MGCL, our Charter provides thatstockholders will not be entitled to exercise appraisal rights unless a majority of the Board shall determine such rights apply. 

***Control ShareAcquisitions***

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

 
 • 
one-tenth or more but less thanone-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 acquirer crosses one of the thresholds of voting power set forth above. Control shares do notinclude 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 control shares, subject to certain exceptions. 

A person who has made or proposes to make a control share acquisition may compel the Board of the corporation to call a special meeting of stockholders to beheld 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 norequest for a meeting is made, the corporation may itself present the question at any stockholders meeting. 

If voting rights are not approved at themeeting 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 beenapproved. The right of the corporation to redeem control shares is subject to certain conditions and limitations, including, as provided in our Bylaws compliance with the 1940 Act. Fair value is determined, without regard to the absence of votingrights for the control shares, as of the date of the last control share acquisition by the acquirer or of any meeting of stockholders at which the voting rights of the shares are considered and not approved. If voting rights for control shares areapproved at a stockholders meeting and the acquirer 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 rightsmay not be less than the highest price per share paid by the acquirer in the control share acquisition. 

The Control Share Act does not apply (a) toshares 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. Our Bylaws contain a provision exempting fromthe Control Share Act any and all acquisitions by any person of our shares of stock. There can be no assurance that such provision will not be amended or eliminated at any time in the future. However, we will amend our Bylaws to be subject to theControl Share Act only if the Board determines that it would be in our best interests and if the SEC staff does not object to our determination that our being subject to the Control Share Act does not conflict with the 1940 Act. 

***Business Combinations***

Under the MGCL,“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 aninterested stockholder. We refer to these provisions 

 
5 

as the Business Combination Act. These business combinations include a merger, consolidation, share exchange or, in circumstances specified in the statute, an asset transfer or issuance orreclassification of equity securities. An interested stockholder is defined as: 

 
 • 
any person who beneficially owns 10% or more of the voting power of the corporation’s outstanding votingstock; or 

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

A person is not an interested stockholder under this statute if the Board approved in advance the transaction by which the stockholder otherwise would havebecome an interested stockholder. However, in approving a transaction, the Board 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 Maryland corporation and an interested stockholder generally must be recommended by theBoard 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 ofthe 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 the MGCL, fortheir shares in the form of cash or other consideration in the same form as previously paid by the interested stockholder for its shares. 

The statutepermits various exemptions from its provisions, including business combinations that are exempted by the Board before the time that the interested stockholder becomes an interested stockholder. Our Board has adopted a resolution that any businesscombination 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 directors who are not “interestedpersons” as defined in the 1940 Act. This resolution may be altered or repealed in whole or in part at any time; however, our Board will adopt resolutions so as to make the Fund subject to the provisions of the Business Combination Act only ifthe Board determines that it would be in our best interests and if the SEC staff does not object to our determination that our being subject to the Business Combination Act does not conflict with the 1940 Act. If this resolution is repealed, or theBoard does not otherwise approve a business combination, the statute may discourage others from trying to acquire control of us and increase the difficulty of consummating any offer. 

***Conflict with 1940 Act***

Our Bylaws provide that,if and to the extent that any provision of the MGCL, including the Control Share Act (if we amend our Bylaws to be subject to such act) and the Business Combination Act, or any provision of our Charter or Bylaws conflicts with any provision of the1940 Act, the applicable provision of the 1940 Act will control. 

***Exclusive Forum***

Our Charter and Bylaws provide that, to the fullest extent permitted by law, unless we consent in writing to the selection of an alternative forum,(i) any derivative action or proceeding brought on behalf of the Fund, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Fund to the Fund or the Fund’s stockholders,(iii) any action asserting a claim arising pursuant to any provision of the MGCL, the Charter or Bylaws or the securities, antifraud, unfair trade practices or similar laws of any international, national, state, provincial,

 
6 

territorial, local or other governmental or regulatory authority, including, in each case, the applicable rules and regulations promulgated thereunder, or (iv) any action asserting a claimgoverned by the internal affairs doctrine shall on the demand of the Fund be resolved through binding and final arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association then in effect. The place ofarbitration shall be New York, New York unless otherwise agreed by the parties; in rendering an award or decision, the arbitrators shall be required to follow the laws of the State of New York; and except as otherwise agreed between the parties,each party involved in a dispute shall bear its own costs and expenses (including attorneys’ fees), and the arbitrators shall not render an award that would include shifting of any such costs or expenses (including attorneys’ fees) or, ina derivative case, award any portion of the Fund’s award to the claimant or the claimant’s attorneys. 

**Term**

As discussed above, if our Board determines it appropriate (and subject to necessary stockholder approvals under our Charter and the 1940 Act, and any otherapplicable requirements of the 1940 Act), the Board may at any time after the third anniversary of the initial closing date, subject to the Adviser’s option to extend this by up to one (1) year beyond the third anniversary of the initialclosing date, or if earlier, the date on which the undrawn capital commitment of each investor has been reduced to zero, (i) (a) create a Liquidating Share Class or effectuate the New BDC Spin-Off,both pending our receipt of exemptive or no-action relief from the SEC, (b) complete a Qualified IPO, or (c) wind up, or (ii) amend the Charter as necessary to preserve (insofar as possible) theoverall benefits previously enjoyed by stockholders as a whole. 

Additionally, if our Board determines that there has been a significant adverse change inour regulatory or tax treatment or that of our stockholders that, in our Board’s judgment makes it inadvisable for the Fund to continue in its present form, then our Board will endeavor to restructure or change the form of the Fund to preserve(insofar as possible) the overall benefits previously enjoyed by stockholders as a whole. 

In the event of and upon any liquidation, dissolution orwinding up of our affairs, whether voluntary or involuntary, after payment or provision for payment of our debts and other liabilities and subject to the prior rights of any outstanding preferred shares, our remaining net assets will be distributedamong holders of our common shares equally on a per share basis. For the purposes of this paragraph, a merger or consolidation of the Fund with or into any other corporation or other entity, or a sale or conveyance of all or any part of our propertyor assets will not be deemed to be a dissolution, liquidation or winding up, voluntary or involuntary.
