Exhibit 4.2
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 150,000,000 shares of common stock, par value $0.01 per share, of which 29,466,768 shares were outstanding as of September 30, 2019.


Our common stock is listed on the Nasdaq Global Select Market under the ticker symbol “OCSI.” 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.


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




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 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 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






112332261v2





		
	•
	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, the affirmative vote of the holders of at least 66 2/3% of the shares of our capital stock entitled to vote will be required to amend or repeal any of the provisions of our bylaws. 
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.
