Description of Securities

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 an exhibit.

    Our authorized capital stock consists of 250,000,000 shares of common stock, par value $0.01 per share, of which 140,960,651 shares were outstanding as of September 30, 2020.

    Our common stock is listed on the Nasdaq Global Select Market under the ticker symbol “OCSL.” No stock has been authorized for issuance under any equity compensation plans. Under Delaware law, our stockholders generally will not be personally liable for our debts or obligations.

    Under the terms of our restated certificate of incorporation, as amended, or our certificate of incorporation, all shares of our common stock have equal rights as to earnings, assets, dividends and voting and, when they are issued, are duly authorized, validly issued, fully paid and nonassessable. Distributions may be paid to the holders of our common stock if, as and when declared by our Board of Directors out of funds legally available therefore. Shares of our common stock have no preemptive, exchange, conversion or redemption rights and are freely transferable, except where their transfer is restricted by federal and state securities laws or by contract. In the event of our liquidation, dissolution or winding up, each share of our common stock would be entitled to share ratably in all of our assets that are legally available for distribution after we pay all debts and other liabilities. 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. The holders of our common stock 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 are able to elect all of our directors, and holders of less than a majority of such shares are unable to elect any director.

    We issued the 3.500% Notes due 2025 (the “Notes”) under a base indenture (the “Base Indenture”), dated as of April 30, 2012, as supplemented by the fifth supplemental indenture, dated as of February 25, 2020 (the “Fifth Supplemental Indenture” and together with the Base Indenture, the “Notes Indenture”), between us and Deutsche Bank Trust Company Americas (the “Trustee”). The Notes are our unsecured obligations and rank senior in right of payment to our existing and future indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to our existing and future unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness (including existing unsecured indebtedness that we later secure) to the extent of the value of the

assets securing such indebtedness; and structurally junior to all existing and future indebtedness (including trade payables) incurred by our subsidiaries, financing vehicles or similar facilities.

    Interest on the Notes is paid semi-annually in arrears on February 25 and August 25 at a rate of 3.500% per annum. The Notes mature on February 25, 2025 and may be redeemed in whole or in part at any time or from time to time at our option. The Notes are not listed on any securities exchange or quoted on any automated dealer quotation system.

    The Notes Indenture contains certain covenants, including a covenant requiring our compliance with Section 18(a)(1)(A) as modified by Section 61(a)(1) and (2) of the Investment Company Act, or any successor provisions, but giving effect to any exemptive relief granted to us by the SEC, and to provide financial information to the holders of the Notes and the Trustee if we should no longer be subject to the reporting requirements under the Exchange Act. These covenants are subject to important limitations and exceptions that are set forth in the Notes Indenture.

    If a change of control repurchase event (as defined in the Fifth Supplemental Indenture) occurs with respect to us, holders of the Notes may require us to repurchase for cash all or part of their Notes. We may satisfy and discharge our obligations under the Notes Indenture, by delivering to the security registrar for cancellation all outstanding Notes or by depositing with the Trustee or delivering to the holders, as applicable, after the Notes have become due and payable, or otherwise, moneys sufficient to pay all of the outstanding Notes and paying all other sums payable under the Notes Indenture by us.

    We may redeem some or all of the Notes at any time, or from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed or (2) the sum of the present values of the remaining scheduled payments of principal and interest (exclusive of accrued and unpaid interest to the date of redemption) on the Notes to be redeemed through January 25, 2025 (the date falling one month prior to the maturity date of the Notes), discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using the applicable Treasury Rate plus 35 basis points, plus, in each case, accrued and unpaid interest to, but excluding, the redemption date; provided, however, that if we redeem any Notes on or after January 25, 2025 (the date falling one month prior to the maturity date of the Notes), the redemption price for the Notes will be equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption. Any exercise of our option to redeem the Notes will be done in compliance with the Investment Company Act.

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

    The term “Event of Default” in respect of the Notes means any of the following:

 

    An Event of Default for a particular series of debt securities does not necessarily constitute an Event of Default for any other series of debt securities issued under the same or any other indenture. The Trustee may withhold notice to the holders of debt securities of any default, except in the payment of principal, premium, interest or sinking or purchase fund installment, if it in good faith considers the withholding of notice to be in the interest of the holders.

    If an Event of Default has occurred and has not been cured, the Trustee or the holders of not less than 25% in principal amount of the applicable series of Notes may (and the Trustee shall at the request of such holders) declare the entire principal amount of all the Notes of that

series to be due and immediately payable. This is called a declaration of acceleration of maturity. A declaration of acceleration of maturity may be canceled by the holders of a majority in principal amount of the debt securities of the affected series if (1) we have deposited with the trustee all amounts due and owing with respect to the securities (other than principal that has become due solely by reason of such acceleration) and certain other amounts, and (2) all Events of Default have been cured or waived.

    The Notes are subject to full defeasance by us if there is a change in U.S. federal tax law or we obtain an IRS ruling. “Defeasance” means that, by depositing with a trustee an amount of cash and/or government securities sufficient to pay all principal and interest, if any, on the Notes when due and satisfying any additional conditions required under the indenture relating to the Notes, we will be deemed to have been discharged from our obligations under the Notes.

    The Notes are subject to covenant defeasance by us. In the event of a “covenant defeasance,” upon depositing such funds and satisfying conditions similar to those for defeasance we would be released from the restrictive covenants under the indenture relating to the Notes. In that event, holders of the Notes would lose the protection of those restrictive covenants but would gain the protection of having money and government securities set aside in trust to repay their debt securities.

    Under our certificate of incorporation, we will fully indemnify any person who was or is involved in any actual or threatened action, suit or proceeding (whether civil, criminal, administrative or investigative) by reason of the fact that such person is or was one of our directors or officers or is or was serving at our request as a director or officer of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, including service with respect to an employee benefit plan, against expenses (including attorney’s fees), judgments, fines and amounts paid or to be paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding. Our certificate of incorporation also provides that our directors will not be personally liable for monetary damages to us for breaches of their fiduciary duty as directors, except for a breach of their duty of loyalty to us or our stockholders, for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, or for any transaction from which the director derived an improper personal benefit. So long as we are regulated under the Investment Company Act, the above indemnification and limitation of liability will be limited by the Investment Company Act or by any valid rule, regulation or order of the SEC thereunder. The Investment Company Act provides, among other things, that a company may not indemnify any director or officer against liability to it or its stockholders to which he or she might otherwise be subject by reason of his or her willful misfeasance, bad faith, gross negligence or reckless

disregard of the duties involved in the conduct of his or her office unless a determination is made by final decision of a court, by vote of a majority of a quorum of directors who are disinterested, non-party directors or by independent legal counsel that the liability for which indemnification is sought did not arise out of the foregoing conduct.

    Delaware law also provides that indemnification permitted under the law shall not be deemed exclusive of any other rights to which the directors and officers may be entitled under the corporation’s bylaws, any agreement, a vote of stockholders or otherwise.

    Our certificate of incorporation permits us to secure insurance on behalf of any person who is or was or has agreed to become a director or officer or is or was serving at our request as a director or officer of another enterprise for any liability arising out of his or her actions, regardless of whether the Delaware General Corporation Law would permit indemnification. We have obtained liability insurance for our officers and directors.

    We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, the statute prohibits a publicly held Delaware corporation from engaging in a “business combination” with “interested stockholders” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes certain mergers, asset sales and other transactions resulting in a financial benefit to the interested stockholder. Subject to exceptions, an “interested stockholder” is a person who, together with his, her or its affiliates and associates, owns, or within three years did own, 15% or more of the corporation’s voting stock.

    Our certificate of incorporation and fourth amended and restated bylaws, or bylaws, provide that:

    The classification of our Board of Directors and the limitations on removal of directors and filling of vacancies could have the effect of making it more difficult for a third party to acquire us, or of discouraging a third party from acquiring us.

    Our certificate of incorporation and bylaws also provide that:

    Our bylaws provide that, in order for any matter to be considered “properly brought” before a meeting, a stockholder must comply with requirements regarding advance notice to us. These provisions could delay until the next stockholders’ meeting stockholder actions which are favored by the holders of a majority of our outstanding voting securities. These provisions may also discourage another person or entity from making a tender offer for our common stock, because such person or entity, even if it acquired a majority of our outstanding voting securities, would be able to take action as a stockholder (such as electing new directors or approving a merger) only at a duly called stockholders meeting, and not by written consent.

    The Delaware General Corporation Law provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws requires a greater percentage. Under our certificate of incorporation and bylaws, any amendment or repeal of the bylaws by the stockholders shall require the affirmative vote of the holders of at least 66 2/3% of the shares of our capital stock then outstanding and entitled to vote in the election of directors. The vote of at least 66 2/3% of the shares of our capital stock then outstanding and entitled to vote in the election of directors, voting together as a single class, will be required to amend or repeal any provision of our certificate of incorporation pertaining to the Board of Directors, limitation of liability, indemnification, stockholder action or amendments to our certificate of incorporation. In addition, our certificate of incorporation permits our Board of Directors to amend or repeal our bylaws by a majority vote.
