(2) Preference on Liquidation.

(a) In the event of the Liquidation (as defined below) of the Corporation, the holder of the Series A Preferred Stock shall be entitled to have paid to it out of the assets of the Corporation available for distribution to stockholders before any distribution is made to or set apart for the holders of Common Stock or other Junior Securities (as defined below), an amount in cash equal to $1.00 per share (the “Series A Preferred Stock Liquidation Preference”).

(b) In the event of a Liquidation, the Corporation shall give, by certified mail, return receipt requested, postage prepaid, addressed to the holder of the share of Series A Preferred Stock at the address of such holder as shown on the books of the Corporation, at least 20 days prior written notice of the date on which the books of the Corporation shall close or a record shall be taken for determining rights to vote in respect of any such Liquidation and of the date when the same shall take place.

(3) Voting. The holder of the share of Series A Preferred Stock shall have the following voting rights:

(a) Except as otherwise required by law or pursuant to this Section 3, the holder of the share of Series A Preferred Stock shall not be entitled to vote on any matters submitted to a vote of the stockholders of the Corporation.

(b) Until a Voting Control Event has occurred, the holder of the Series A Preferred Stock shall have the right, voting separately as a class, at each meeting of the holder of the Series A Preferred Stock held for the purpose of electing one director of the Corporation (the “Series A Director”).

At any meeting held for the purpose of electing directors, the presence in person or by proxy of the holder of the outstanding share of Series A Preferred Stock shall be required and be sufficient to constitute a quorum of such class for the election of the Series A Director by such class. At any such meeting or adjournment thereof, the absence of a quorum of the holder of Series A Preferred Stock shall not prevent the election of directors other than the Series A Director and the absence of a quorum or quorums of the holders of capital stock of the Corporation entitled to elect such other directors shall not prevent the election of the Series A Director. In the case of any vacancy occurring with respect to the Series A Director, such vacancy shall only be filled by the holder of the outstanding Series A Preferred Stock, voting separately as a class.

(c) The affirmative vote of the holder of the outstanding Series A Preferred Stock shall be required for any amendment, alteration or repeal (including by merger, consolidation or otherwise by operation of law) of any provisions of this Certificate of Incorporation or the By-Laws that would adversely affect the powers, preferences, privileges or rights of the Series A Preferred Stock or of the holder thereof in such capacity.

holder of the Series A Preferred Stock shall thereafter have no voting rights, except as otherwise required by applicable law.

(4) Redemption.

(a) Upon the occurrence of the Voting Control Event, to the extent the Corporation shall have funds legally available for such payment, the Corporation shall promptly redeem the share of Series A Preferred Stock at a redemption price per share in cash equal to the Series A Preferred Stock Liquidation Preference (the “Redemption Price”).

(b) If the Corporation shall redeem the share of Series A Preferred Stock pursuant to this Section 4, notice of such redemption shall be given by certified mail, return receipt requested, postage prepaid, mailed not less than two days nor more than 45 days prior to the redemption date, to the holder of record of the share to be redeemed at such holder’s address as the same appears on the stock books of the Corporation or its transfer agent. Any notice that was mailed in the manner herein provided shall be conclusively presumed to have been duly given on the date mailed whether or not the holder receives the notice. Each such notice shall state: (i) the redemption date; and (ii) the place or places where the certificate for such share is to be surrendered for payment of the Redemption Price.

(c) Upon surrender in accordance with notice given pursuant to this Section 4 (properly endorsed or assigned for transfer, if the Board of Directors of the Corporation shall so require and the notice shall so state), such share shall be redeemed by the Corporation at the Redemption Price.

(d) If notice has been mailed as aforesaid, from and after the redemption date (unless default shall be made by the Corporation in providing for the payment of the Redemption Price of the share called for redemption), (i) said share shall no longer be deemed to be outstanding and (ii) all rights of the holder thereof as holder of the Series A Preferred Stock shall cease (except the right to receive from the Corporation the Redemption Price without interest thereon, upon surrender and endorsement of its certificates if so required).

(5) Merger or Consolidation. Unless a Voting Control Event has occurred, in the event of a merger or consolidation of the Corporation with or into any person pursuant to which the corporation shall not be the continuing person, the Series A Preferred Stock shall be converted into or exchanged for and shall become a preferred share of such successor or resulting company or, at the Corporation’s sole discretion, the parent of such successor or resulting company, having in respect of such successor or resulting company or parent of such successor or resulting company, substantially the same powers, preferences and relative participating, optional or other special rights, and the qualifications, limitations or restrictions thereon, that the Series A Preferred Stock had immediately prior to such transaction.

(6) Limitation and Rights Upon Insolvency. Notwithstanding any other provision of this Certificate of Designations, the Corporation shall not be required to pay any amount in respect to any redemption of the Series A Preferred Stock at a time when immediately after making such payment the Corporation is or would be rendered insolvent (as defined by

applicable law), provided that the obligation of the Corporation to make any such payment shall not be extinguished in the event the foregoing limitation applies.

(7) Share to be Retired. When the share of Series A Preferred Stock is redeemed, exchanged or otherwise acquired by the Corporation, it shall be retired and canceled.

(8) Transfer Restrictions. The holder of Series A Preferred Stock may not effect any offer, sale, pledge, transfer or other disposition or distribution (or enter into any agreement with respect to any of the foregoing) (a “Transfer”) of the share of Series A Preferred Stock, except (a) a Transfer to any SLP Investor or (b) a Transfer to any other person in connection with the consummation of a transaction pursuant to Section 3.5 of the Stockholders Agreement in which the holder of Series A Preferred Stock does not receive any consideration with respect to such Transfer of Series A Preferred Stock (for the avoidance of doubt, it being understood that this clause (b) shall in no manner limit the amount or type of consideration that the holder of Series A Preferred Stock may receive in connection with such transaction with respect to any other securities of the Company beneficially owned by such holder).
