Exhibit 4.8
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.
		
	(a)
	Common Stock, $0.01 par value per share 




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, 2019.


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 authorized by our Board of Directors and declared by us 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.

2024 Notes


The 2024 Notes (together with the 2028 Notes, the “Notes”) were issued under a base indenture (the “Base Indenture”), dated as of April 30, 2012, as supplemented by the first supplemental indenture, dated as of October 18, 2012, between us and Deutsche Bank Trust Company Americas (“Deutsche Bank”). The 2024 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 2024 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 




112247070v2





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 or financing vehicles.


Interest on the 2024 Notes is paid quarterly in arrears on January 30, April 30, July 30 and October 30 at a rate of 5.875% per annum. The 2024 Notes mature on October 30, 2024 and may be redeemed in whole or in part at any time or from time to time at our option on or after October 30, 2017. The 2024 Notes currently trade on the New York Stock Exchange under the symbol “OSLE” with a par value of $25.00 per note.


The 2024 Notes Indenture contains certain covenants, including covenants requiring our compliance with (regardless of whether we are subject to) the asset coverage requirements set forth in Section 18(a)(1)(A) as modified by Section 61(a)(1) of the Investment Company Act or any successor provisions and with the restrictions on dividends, distributions and purchase of capital stock set forth in Section 18(a)(1)(B) as modified by Section 61(a)(1) of the Investment Company Act, as well as covenants requiring us to provide financial information to the holders of the 2024 Notes and the Trustee if we cease to be subject to the reporting requirements of the Exchange Act. These covenants are subject to limitations and exceptions that are described in the 2024 Notes Indenture. We may repurchase the 2024 Notes in accordance with the Investment Company Act and the rules promulgated thereunder. Any 2024 Notes repurchased by us may, at our option, be surrendered to the Trustee for cancellation, but may not be reissued or resold by us. Any 2024 Notes surrendered for cancellation will be promptly canceled and no longer outstanding under the 2024 Notes Indenture.


2028 Notes
    
The 2028 Notes were issued under the Base Indenture as supplemented by the second supplemental indenture, dated as of April 4, 2013, between us and Deutsche Bank. The 2028 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 2028 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 it later secures) 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 or financing vehicles.


Interest on the 2028 Notes is paid quarterly in arrears on January 30, April 30, July 30 and October 30 at a rate of 6.125% per annum. The 2028 Notes mature on April 30, 2028 and may be redeemed in whole or in part at any time or from time to time at our option on or after April 30, 2018. The 2028 Notes currently trade on the Nasdaq Stock Market LLC under the symbol "OCSLL" with a par value of $25.00 per note.


The 2028 Notes Indenture contains certain covenants, including covenants requiring our compliance with (regardless of whether it is subject to) the asset coverage requirements set forth in Section 18(a)(1)(A) as modified by Section 61(a)(1) of the Investment Company Act or any 




112247070v2





successor provisions, as well as covenants requiring us to provide financial information to the holders of the 2028 Notes and the Trustee if we cease to be subject to the reporting requirements of the Exchange Act. These covenants are subject to limitations and exceptions that are described in the 2028 Notes Indenture. We may repurchase the 2028 Notes in accordance with the Investment Company Act and the rules promulgated thereunder. Any 2028 Notes repurchased by us may, at our option, be surrendered to the Trustee for cancellation, but may not be reissued or resold by us. Any 2028 Notes surrendered for cancellation will be promptly canceled and no longer outstanding under the 2028 Notes Indenture.


Conversion and Exchange 


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


Events of Default 


The term “Event of Default” in respect of the Notes means any of the following:  
	
				
	 
	•
	 
	We do not pay the principal of, or any premium on, a debt security of the series on its due date;






	
				
	 
	•
	 
	We do not pay interest on a debt security of the series within 30 days of its due date;






	
				
	 
	•
	 
	We do not deposit any sinking fund payment in respect of debt securities of the series within 2 business days of its due date;






	
				
	 
	•
	 
	We remain in breach of a covenant in respect of debt securities of the series for 60 days after a written notice of default has been given stating we are in breach.  The notice must be sent to us by the trustee or to us and the Trustee by the holders of at least 25% of the principal amount of debt securities of the series;






	
				
	 
	•
	 
	We file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur; or






	
				
	 
	•
	 
	Any class of debt securities has an asset coverage, as such term is defined in the Investment Company Act, of less than 100 per centum on the last business day of each of twenty-four consecutive calendar months (which Event of Default is not applicable to the 2028 Notes).




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.


Remedies if an Event of Default Occurs 






112247070v2





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. 


Defeasance and Covenant Defeasance 
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.


Indenture Provisions—Ranking 
The Notes are our direct unsecured obligations and rank:  	
				
	 
	•
	 
	pari passu with our other outstanding and future unsecured indebtedness; 




 
	
				
	 
	•
	 
	senior to any of our future indebtedness that expressly provides it is subordinated to the Notes;




 
	
				
	 
	•
	 
	effectively subordinated to all of our existing and future secured indebtedness (including indebtedness that is initially unsecured to which we subsequently grant security), to the extent of the value of the assets securing such indebtedness; and




 
	
				
	 
	•
	 
	structurally subordinated to all existing and future indebtedness of any of our subsidiaries.






		
	(c)
	Provisions of our Certificate of Incorporation or Bylaws that may have the effect of delaying, deferring or preventing a change of control








112247070v2





Limitation on Liability of Directors and Officers; Indemnification and Advance of Expenses 
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.
Delaware Law and Certain Certificate of Incorporation and Bylaw Provisions; Anti-Takeover Measures 
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 




112247070v2





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 Board of Directors be divided into three classes, as nearly equal in size as possible, with staggered three-year terms; 






	
				
	 
	•
	 
	directors may be removed only for cause by the affirmative vote of the holders of two-thirds of the shares of our capital stock entitled to vote; and






	
				
	 
	•
	 
	any vacancy on the Board of Directors, however the vacancy occurs, including a vacancy due to an enlargement of the Board of Directors, may only be filled by vote of the directors then in office.






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:
	
				
	 
	•
	 
	any action required or permitted to be taken by the stockholders at an annual meeting or special meeting of stockholders may only be taken if it is properly brought before such meeting and may not be taken by written action in lieu of a meeting; and






	
				
	 
	•
	 
	special meetings of the stockholders may only be called by our Board of Directors, chairman or chief executive officer.






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 




112247070v2





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.
