The Corporation shall, from time to time, in accordance with the laws of the State of Iowa, increase the authorized number of shares of Common Stock if at any time the number of shares of authorized and unissued Common Stock shall not be sufficient to permit the conversion of all the then outstanding shares of Series A Convertible Preferred Stock. (ii) The Corporation will pay any and all stamp and transfer taxes that may be payable in respect of the issuance or delivery of shares of Common Stock upon conversion of shares of Series A Convertible Preferred Stock pursuant hereto.

(e) In case of (i) any reclassification or change of outstanding shares of Common Stock (other than a change in par value or from par value to no par value or from no par value to par value, or as a result of a subdivision or combination) or (ii) any consolidation or merger of the Corporation with one or more other corporations (other than a consolidation or merger in which the Corporation is the continuing corporation and which does not result in any reclassification or change of outstanding shares of Common Stock issuable upon conversion of Series A Convertible Preferred Stock) or (iii) any sale or conveyance to another corporation or other entity of all or substantially all of the property of the Corporation, then the Corporation, or such successor corporation or other entity, as the case may be, shall make appropriate provision so that the holder of each share of Series A Convertible Preferred Stock then outstanding shall have the right to convert such share into the kind and amount of shares of stock or other securities and property receivable upon such consolidation, merger, sale, reclassification, change or conveyance by a holder of the number of shares of Common Stock into which such shares of Series A Convertible Preferred Stock might have been converted immediately prior to such consolidation, merger, sale, reclassification, change or conveyance, subject to adjustment which shall be as nearly equivalent as may be practicable to the adjustments provided for in Section 6(c). If the holders of Common Stock are entitled to elect the consideration payable pursuant any consolidation, merger, sale, conveyance or other transaction or event set forth above, the Holders also shall be entitled to elect between such forms of consideration. The provisions of this paragraph shall apply similarly to successive consolidations, mergers, sales, conveyances or other transactions or events. (f) Whenever the number of shares of Common Stock into which each share of Series A Convertible Preferred Stock is convertible is adjusted as provided in this Section 6, the Corporation shall promptly mail to the Holders a notice in accordance with Section 8 below stating that the number of shares of Common Stock into which the shares of Series A Convertible Preferred Stock are convertible has been adjusted and setting forth the new number of shares of Common Stock (or describing the new stock, securities, cash or other property) into which each share of Series A Convertible Preferred Stock is convertible, as a result of such adjustment, a brief statement of the facts requiring such adjustment and the computation thereof, and when such adjustment became effective. 7.
