(c) Liquidation, Dissolution, or Winding Up. In the event of a dissolution, liquidation or winding up of the affairs of the Corporation (“Liquidation”), holders

of Common Shares shall be entitled, unless otherwise provided by law or this Certificate of Incorporation, to receive all of the remaining assets of the Corporation of whatever kind available for distribution to stockholders ratably in proportion to the number of Common Shares held by them respectively.

Section 4.3 Preferred Shares.

(a) The Preferred Shares may be issued in one or more series as shall from time to time be created and authorized to be issued by the Board of Directors as hereinafter provided.

(b) The Board of Directors is expressly authorized to provide for the issuance of all or any of the Preferred Shares in one or more classes or series, and to fix for each such class or series such voting powers, full or limited, or no voting powers, and such distinctive designations, preferences and relative, participating, optional or other special rights and such qualifications, limitations or restrictions thereof, as shall be stated and expressed in the resolution or resolutions adopted by the Board of Directors providing for the issuance of such class or series and as may be permitted by the GCL, including, without limitation, the authority to provide that any such class or series may be (i) subject to redemption at such time or times and at such price or prices; (ii) entitled to receive dividends (which may be cumulative or non-cumulative) at such rates, on such conditions, and at such times, and payable in preference to, or in such relation to, the dividends payable on any other class or classes or any other series; (iii) entitled to such rights upon the dissolution of, or upon any distribution of the assets of, the Corporation; or (iv) convertible into, or exchangeable for, shares of any other class or classes of stock, or of any other series of the same or any other class or classes of stock, of the Corporation at such price or prices or at such rates of exchange and with such adjustments; all as may be stated in such resolution or resolutions. Any of the foregoing provisions shall be consistent with the requirements of the Investment Company Act of 1940 (the “1940 Act”) to the extent applicable.

(c) Each share of each series of the Preferred Shares shall have the same relative rights and be identical in all respects with all the other shares of the same series, except that shares of any one series issued at different times may differ as to the dates, if any, from which dividends thereon shall be cumulative. Except as otherwise provided by law or specified in this Article IV, any series of the Preferred Shares may differ from any other series with respect to any one or more of the voting powers, designations, powers, preferences and relative, participating, optional and other special rights, if any, and the qualifications, limitations and restrictions thereof.

(d) Before any dividends on any class of stock of the Corporation ranking junior to the Preferred Shares (other than dividends payable in shares of any class of stock of the Corporation ranking junior to the Preferred Shares) shall be declared or paid or set apart for payment, the holders of shares of each series of the Preferred Shares shall be entitled to such cash dividends, but only if, when and as declared by the Board of Directors out of funds legally available therefor, as they may be entitled to in accordance with the resolution or resolutions adopted by the Board of Directors providing for the issuance of such series, payable on such dates as may be fixed in such resolution or resolutions.

2

(e) In the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, before any payment or distribution of the assets of the Corporation shall be made to or set apart for the holders of shares of any class of stock of the Corporation ranking junior to the Preferred Shares, the holders of the shares of each series of the Preferred Shares shall be entitled to receive payment of the amount per share fixed in the resolution or resolutions adopted by the Board of Directors providing for the issuance of the shares of such series, plus an amount equal to all dividends accrued thereon to the date of final distribution to such holders. If, upon any liquidation, dissolution or winding up of the Corporation, the assets of the Corporation, or proceeds thereof, distributable among the holders of the shares of the Preferred Shares shall be insufficient to pay in full the preferential amount aforesaid, then such assets, or the proceeds thereof, shall be distributed among such holders ratably in accordance with the respective amounts which would be payable on such shares if all amounts payable thereon were paid in full. For the purposes of this paragraph (d), the sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Corporation or a consolidation or merger of the Corporation with one or more corporations shall not be deemed to be a dissolution, liquidation or winding up, voluntary or involuntary.

(f) The term “junior stock,” as used in relation to the Preferred Shares, shall mean the Common Shares and any other class of stock of the Corporation hereafter authorized which by its terms shall rank junior to the Preferred Shares as to dividend rights and as to the distribution of assets upon liquidation, dissolution or winding up of the Corporation.

(g) Before the Corporation shall issue any Preferred Shares of any series authorized as hereinbefore provided, a certificate setting forth a copy of the resolution or resolutions with respect to such series adopted by the Board of Directors of the Corporation pursuant to the foregoing authority vested in said Board of Directors shall be made, filed and recorded in accordance with the then applicable requirements, if any, of the laws of the State of Delaware, or, if no certificate is then so required, such certificate shall be signed and acknowledged on behalf of the Corporation by its president or a vice-president and its corporate seal shall be affixed thereto and attested by its secretary or an assistant secretary and such certificate shall be filed and kept on file at the registered office of the Corporation in the State of Delaware and in such other place or places as the Board of Directors shall designate.

(h) Shares of any series of the Preferred Shares which shall be issued and thereafter acquired by the Corporation through purchase, redemption, conversion or otherwise, shall return to the status of authorized but unissued shares of the Preferred Shares of the same series unless otherwise provided in the resolution or resolutions of the Board of Directors. Unless otherwise provided in the resolution or resolutions of the Board of Directors providing for the issuance thereof, the number of authorized shares of stock of any such series may be increased or decreased (but not below the number of shares thereof then outstanding) by resolution or resolutions of the Board of Directors and the filing of a certificate complying with the requirements referred to in subparagraph (g) above. In case the number of shares of any such series of the Preferred Shares shall be decreased, the shares representing such decrease shall, unless otherwise provided in the resolution or resolutions of the Board of Directors providing for the issuance thereof, resume the status of authorized but unissued shares of the Preferred Shares, undesignated as to series.

ARTICLE V

Section 5.1 In-Kind Distributions. Section 4.2(c) notwithstanding, the Corporation shall not make a distribution in kind of any securities to any holder of the shares of the Corporation in connection with a Liquidation, if such distribution would in the reasonable judgment of such holder cause such holder to be in violation of any law applicable to such holder (“ERISA Shareholder”); provided that the ERISA Shareholder shall notify the Corporation to such effect not less than five days prior to such distribution. In the event an ERISA Shareholder notifies the Corporation as provided in the immediately preceding sentence, the Corporation shall use its reasonable best efforts to cause the securities or other assets otherwise distributable to the ERISA Shareholder (the “Subject Securities”) to be sold to a third party, who may be another holder of shares in the Corporation, for the best consideration available under the circumstances, as determined by the Board of Directors in its reasonable discretion, and, upon consummation of any such sale, the cash proceeds from such sale shall be distributed to the ERISA Shareholder. In the event such a sale cannot be consummated for the best consideration available under the circumstances and within a reasonable period of time following the time of the proposed distribution (in no case to exceed two years), the obligation of the Corporation to the ERISA Shareholder shall be extinguished by establishing, with an escrow agent designated by the ERISA Shareholder, an escrow account for the benefit of the ERISA Shareholder into which the Subject Securities shall be deposited, which account shall be liquidated at such time as a sale can be accomplished on the terms set forth above; provided that from and after the time of such deposit such Subject Securities shall be deemed for all purposes of this Certificate of Incorporation to have been distributed to the ERISA Shareholder and any income arising from the Subject Securities shall be deposited in such account for the benefit of the ERISA Shareholder.

ARTICLE VI

Section 6.1 Classified Board. At such time that the Public Market Event occurs, the Board of Directors shall be divided into three classes, designated Class I, Class II and Class III, as nearly equal in number as possible, and the term of office of directors of one class shall expire at each annual meeting of stockholders, and in all cases as to each director when such director’s successor shall be elected and shall qualify or upon such director’s earlier resignation, removal from office, death or incapacity. Additional directorships resulting from an increase in number of directors shall be apportioned among the classes as equally as possible. If required by law, the initial term of office of directors of Class I shall expire at the annual meeting of stockholders in the first year after the Public Market Event; that of Class II shall expire at the annual meeting in the second year after the Public Market Event; and that of Class III shall expire at the annual meeting in the third year after the Public Market Event; and in all cases as to each director when such director’s successor shall be elected and shall qualify or upon such director’s earlier resignation, removal from office, death or incapacity. Beginning at the first annual meeting after the Public Market Event and thereafter at each annual meeting, the number of directors equal to the number of directors of the class whose term expires at the time of such meeting (or, if less, the number of directors properly nominated and qualified for election) shall be elected to hold office until the third succeeding annual meeting of stockholders after their election.

4

Section 6.6 Vacancies. Subject to the rights of the holders of any series of Preferred Shares, and unless the Board of Directors otherwise determines, all vacancies on the Board of Directors and newly created directorships resulting from any increase in the authorized number of directors shall be filled exclusively by a majority of the directors then in office, although less than a quorum, or by a sole remaining director, and shall not be filled by the stockholders.
