is determined under the following conversion formula. Each share of ESOP Preferred Stock will be converted into a number of shares of Common Stock equal to (i) the Adjusted Common Stock Value divided by (ii) 500,000 shares divided by (iii) the Common Stock Price. In the event the ESOP Preferred Stock is converted pursuant to the Alternative Conversion Right set forth in this Section 6(b), the entire unpaid principal balance and any and all interest accrued on such unpaid principal balance owing under the Purchase Money Note shall immediately become due and payable.

(i) In order to convert shares of ESOP Preferred Stock into shares of Common Stock pursuant to this Section 6, the Plan shall deliver to the Company at its principal executive offices or another place designated by the Company in a written notice sent to the Plan, a Conversion Notice, in form satisfactory to the Company, duly executed by the Plan. Each Conversion Notice shall specify (1) the number of shares of ESOP Preferred Stock to be converted and (2) whether the ESOP Preferred Stock is being converted pursuant to the Conversion Right set forth in Section 6(a) of this Division A-2 or the Alternative Conversion Right set forth in Section 6(b) of this Division A-2. Any conversion pursuant to this Section 6 shall be deemed to have been effected at the close of business on the Business Day on which the Conversion Notice has been received by the Company (a “Conversion Date”).

(ii) The Company shall, as soon as practicable after the Conversion Date, cause to be issued and delivered to the person specified in the Conversion Notice the number of full shares of Common Stock to which such person shall be entitled, together with a cash payment in respect of any fractional shares of Common Stock otherwise issuable. The person or persons entitled to receive the shares of Common Stock deliverable upon conversion of such shares of ESOP Preferred Stock shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the relevant Conversion Date, unless the stock transfer books of the Company shall be closed on such Conversion Date, in which event such person or persons shall be deemed to have become such holder or holders of record at the close of business on the next succeeding day on which such stock transfer books are open.

(d) Fractional Shares. No fractional shares or scrip representing fractional shares of Common Stock shall be issued upon conversion of any shares of ESOP Preferred Stock. If more than one share of ESOP Preferred Stock shall be surrendered for conversion at one time by the same record holder, the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of ESOP Preferred Stock which are converted. In lieu of any fractional share of Common Stock that would otherwise be issuable upon conversion of any shares of ESOP Preferred Stock, the Company shall pay a cash adjustment in respect of such fractional share in lieu thereof, calculated to the nearer cent, with one-half cent or more rounded upward.

(e) Reservation and Authorization of Shares. The Company shall at all times when the ESOP Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued Common Stock or treasury shares of Common Stock, for the purpose of effecting the conversion of the ESOP Preferred Stock, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of ESOP Preferred Stock.

(f) Converted Shares. After the Conversion Date with respect to any shares of ESOP Preferred Stock, such shares shall no longer be deemed to be outstanding and all rights with respect to such shares, including but not limited to the rights, if any, to receive notices or distributions and to vote, shall immediately cease and terminate on the Conversion Date, except only the right of the holders thereof to receive shares of Common Stock (and cash in lieu of fractional shares) in exchange therefor.

(a) Redemption Right and Shares Released from the ESOP Loan Suspense Account. All or any portion (including fractions of a share) of the outstanding shares of ESOP Preferred Stock shall be redeemable, at the option of the Plan at any time and from time to time. In addition, all or any portion (including fractions of a share) of the ESOP Preferred Stock shall be redeemed without notice as and when such shares are released from the ESOP Loan Suspense Account, unless the Plan exercises its conversion rights with respect to such shares by delivering a Conversion Notice to the Company prior to such release. The amount paid by the Company for shares so redeemed shall be equal to the Redemption Price.

(b) Notice of Redemption. In the event of a redemption pursuant to the first sentence of Section 7(a) of this Division A-2, the Plan shall give notice (a “Redemption Notice”) to the Company. Each Redemption Notice shall specify (i) the Redemption Date (which may be the date the Redemption Notice is given), (ii) the number of shares of ESOP Preferred Stock to be redeemed or the aggregate Redemption Price for all shares of ESOP Preferred Stock to be redeemed as of the applicable Redemption Date, (iii) the place or places for payment of the Redemption Price, (iv) that payment will be made upon surrender of shares of ESOP Preferred Stock, and (v) that the right of holders to convert shares of ESOP Preferred Stock shall terminate at the close of business on the Redemption Date (unless the Company defaults in the payment of the Redemption Price). In the event of a redemption pursuant to the second sentence of Section 7(a) of this Division A-2, the Plan is not required to provide a Redemption Notice to the Company and the Redemption Date shall be the date on which the shares of the ESOP Preferred Stock are released from the ESOP Loan Suspense Account.

(c) Redemption Procedures. On the Redemption Date, the Plan shall surrender the shares of ESOP Preferred Stock to the Company and shall thereupon be entitled to receive payment of the applicable Redemption Price for each such share. If a Redemption Notice shall have been given, as aforesaid, and if, on the Redemption Date, assets necessary for the redemption shall be legally available therefor and shall have been irrevocably deposited, set aside for or paid (including, payment in the form of debt forgiveness) to the Plan, then, notwithstanding that the redeemed shares of ESOP Preferred Stock shall not have been surrendered, (i) such shares shall no longer be deemed outstanding, (ii) the Plan shall cease to be a stockholder of the Company to the extent of its interest in such shares, and (iii) all rights whatsoever with respect to such shares of ESOP Preferred Stock shall terminate, except the right to receive the Redemption Price for each such share, without interest or any sum of money in lieu of interest thereon. Redemptions of ESOP Preferred Stock shall be effected as of the close of business on the Redemption Date before effecting any conversion for which the Conversion Date corresponds with the Redemption Date.

(d) No Sinking Fund. The shares of ESOP Preferred Stock shall not be subject to the operation of any retirement or sinking fund.

(e) Redeemed Shares. After the Redemption Date with respect to any shares of ESOP Preferred Stock redeemed pursuant to this Section 7, such shares shall no longer be deemed to be outstanding and all rights with respect to such shares, including but not limited to the rights, if any, to receive notices or distributions and to vote, shall immediately cease and terminate on the Redemption Date, except only the right of the holders thereof to receive the Redemption Price therefor, without interest or any sum of money in lieu of interest thereon. Any shares of ESOP Preferred Stock redeemed pursuant to this Section 7 shall be retired and canceled after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Serial Preferred Stock and may be reissued as part of a new series of Serial Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to the conditions and restrictions set forth herein.

(f) Payment of Redemption Price. The Company, at its option, may make payment of the Redemption Price (i) in cash, (ii) in shares of Common Stock which are readily tradable on an established

-6-

securities market (as such phrase is interpreted under the Code and any regulations issued pursuant thereto), or (iii) in any combination of any of the foregoing. For purposes of determining the number of shares of Common Stock to be delivered by the Company in satisfaction, in whole or in part, of any Redemption Price, shares of Common Stock shall be valued at the Common Stock Price as of the Redemption Date.

Section 8. Liquidation.

(a) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company (hereinafter referred to as a “Liquidation”), no distribution shall be made to the holders of shares of stock ranking junior (either as to dividends or upon Liquidation) to the ESOP Preferred Stock, unless, prior thereto, the holders of shares of ESOP Preferred Stock shall have received at least an amount per share equal to $1,000, plus an amount equal to accrued and unpaid dividends thereon, whether or not earned or declared, to the date of such payment (the “ESOP Preferred Stock Liquidation Preference”).

(b) In the event, however, that the net assets of the Company are not sufficient to pay in full the amount of the ESOP Preferred Stock Liquidation Preference and the liquidation preferences of all other series of Serial Preferred Stock, if any, which rank on a parity with the ESOP Preferred Stock as to distribution of assets in Liquidation, all shares of this Series and of such other series of Serial Preferred Stock shall share ratably in the distribution of assets (or proceeds thereof) in Liquidation in proportion to the full amounts to which they are respectively entitled.

(c) The merger or consolidation of the Company into or with any other Company, or the merger of any other corporation into it, or the sale, lease or conveyance of all or substantially all the property or business of the Company, shall not be deemed to be a Liquidation for the purposes of this Section 8.
