of such share and (y) an amount per share equal to the amount per share of dividends, if any, paid on the Common Stock and no more.

Dividends on each share of Class A Preferred Stock shall be cumulative from the date of original issue of such share and shall be payable, when and as declared by the Board of Directors of the corporation, provided, that any dividend required to be paid pursuant to clause (y) of the preceding paragraph shall be paid simultaneously with the corresponding dividend on the Common Stock. Each such dividend shall be paid to the holders of record as they appear on the stock register of the corporation on such record date as shall be fixed by the Board of Directors of the corporation.

Liquidation Rights. Upon the dissolution, liquidation or winding up of the corporation, (i) the holders of Class A Preferred Stock shares shall be entitled to receive and to be paid out of the assets of the corporation available for distribution to its stockholders, before any payment to holders of Common Stock pursuant to clause (ii) below, the amount per share equal to the stated value of such share when originally issued, plus a sum equal to all dividends on such shares accrued and unpaid thereon to the date of final distribution, and thereafter (ii) the holders of Common Stock shall be entitled to receive and to be paid out of the assets of the corporation available for distribution to its stockholders the amount per share equal to the par value of such share when originally issued.

After the payment to the holders of Class A Preferred Stock and the payment to the holders of Common Stock of the full amounts set forth above, the holders of Class A Preferred Stock shall share the remaining assets of the corporation with the holders of Common Stock, with each share of Class A Preferred Stock being entitled to receive the same amount as is distributed in respect of each share of Common Stock.

In the event the assets of the corporation available for distribution to the holders of the shares of Class A Preferred Stock upon any dissolution, liquidation or winding up of the corporation, whether voluntary or involuntary, shall be insufficient to pay in full all amounts to which such holders are entitled, such assets of the corporation available for distribution shall be distributed ratably to the holders of all outstanding shares of Class A Preferred Stock and all such other shares of the corporation ranking pari passu in proportion to the amounts to which they shall be respectively entitled.

Neither the sale, lease or exchange (for cash, shares of stock, securities or other consideration) of all or substantially all the property and assets of the corporation nor the merger or consolidation of the corporation into or with any other corporation or the merger or consolidation of any other corporation into or with the corporation, shall be deemed to be a dissolution, liquidation or winding up, voluntary or involuntary, for the purposes of this Section.

Redemption. The shares of Class A Preferred Stock shall not be subject to redemption at the election of the corporation, except that any affiliate of the corporation may at any time or from time to time purchase shares of the Class A Preferred Stock pursuant to the terms of the corporation’s stock option plan in effect on such date of redemption or pursuant to any other agreement between the holder of the shares and the corporation or such affiliate for the price specified in such plan or agreement.

Conversion. The holders of the shares of the Class A Preferred Stock shall have no right to convert such shares into shares of any other class or series of capital stock of the corporation.

Voting Rights. The number of authorized shares of Class A Preferred Stock may be increased or decreased by the affirmative vote of a majority of stock of the corporation. Except as provided in the previous sentence or otherwise required by law, the holder of the Class A Preferred Stock shall not have the right to vote on any matters. If entitled to vote, the Class A Preferred Stock shall vote as a class with the common stock of the corporation with each share of Class A Preferred Stock having one hundredth (1/100th) of a vote per share.

Ranking. Except as otherwise set forth in this paragraph 5, the Class A Preferred Stock shall be deemed to rank

pari passu with the common stock of the corporation.

6. The corporation is to have perpetual existence.

7. In furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized to make, alter or repeal the by-laws of the corporation.

8. Elections of directors need not be by written ballot unless the by-laws of the corporation shall so provide.

9. A director or officer of the corporation shall not be liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except to the extent that such exemption from liability or limitation thereof is not permitted under the Delaware General Corporation Law as currently in effect or as the same may hereafter be amended. No amendment, modification or repeal of this Article 9 shall adversely affect any right or protection of a director that exists at the time of such amendment, modification or repeal.
