D.            For federal income tax purposes, it is intended that the above-described merger shall qualify as a reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended (the “Code”), and that this Agreement shall constitute a plan of reorganization pursuant to Section 368 of the Code.

NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained, the parties hereby agree as follows:

1.             Merger.  On the Effective Date (as defined in Section 2 hereof), Parent shall be merged with and into Subsidiary, with Subsidiary being the surviving corporation (the “Merger”), pursuant to the applicable provisions of the Minnesota Business Corporation Act, including Section 302A.621 thereof, and the Delaware General Corporation Law.

3.             Surviving Corporation.  On the Effective Date, the separate corporate existence of Parent shall cease, and the Constituent Corporations shall become a single corporation with Subsidiary being the surviving corporation.  Thereafter, Subsidiary, as the surviving corporation, shall have all of the rights, privileges, immunities and powers, and will be subject to all of the duties and liabilities of a corporation incorporated under the laws of the State of Delaware.  In addition, as the surviving corporation, Subsidiary shall possess all of the rights, privileges, immunities and franchises, of a public as well as of a private nature, of each of the Constituent Corporations, and all property, real, personal and mixed, and all debts due on any account, including subscriptions to shares, and all other causes of action, and every other interest of or belonging to or due to each of the Constituent Corporations shall vest in Subsidiary as the surviving corporation, without any further act or deed.

On the Effective Date, Subsidiary, as the surviving corporation, shall become responsible and liable for all the liabilities and obligations of each of the Constituent Corporations, and a claim of or against, or a pending proceeding by or against either of the Constituent Corporations may be prosecuted as if the Merger had not taken place, or Subsidiary, as the surviving corporation, may be substituted in the place of Parent.  Neither the rights of creditors nor any liens upon the property of either of the Constituent Corporations shall be impaired by the Merger.

4.             Stock Exchange.

a.             Subsidiary Shareholder.  In connection with the Merger, all of the presently outstanding shares of capital stock of Subsidiary shall be cancelled, and no stock shall be issued to Parent, the sole shareholder of Subsidiary, as a result of the Merger of Parent into Subsidiary.  Parent, the sole shareholder of Subsidiary, shall surrender its stock certificate(s) representing such shares of Subsidiary endorsed in blank or accompanied by an appropriate stock power executed in blank.

b.             Parent Shareholders.  On the Effective Date, each share of the common stock of Parent issued and outstanding immediately before the Effective Date shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into and become one share of common stock of Subsidiary.  Each share of common stock of Subsidiary issued pursuant to this section shall be fully paid and nonassessable and shall be deemed to have been issued as of the Effective Date.  The outstanding certificates representing shares of common stock of Parent will, after the Effective Date, be deemed to represent the number of shares of common stock of Subsidiary into which they have been converted.  Upon surrender of stock certificates representing the common stock of Parent from each shareholder of Parent, Subsidiary
