shares and other choses in action belonging to any of the Constituent Entities, and all and every other interest shall be deemed to be transferred to and vested in the Surviving Entity without further act or deed; and all rights of creditors and all liens upon any property of any of the Constituent Entities shall be preserved unimpaired; and all debts, liabilities and duties of any of the Constituent Entities shall thenceforth attach to the Surviving Entity, and may be enforced against the Surviving Entity, to the same extent as if said debts, liabilities and duties had been incurred or contracted by the Surviving Entity, all with the effect set forth in the Indiana Act and the Wisconsin Act.

2. Articles of Incorporation; Amendment. The Articles of Incorporation of the Corporation, as amended, and as in effect immediately prior to the Effective Date, shall be the Articles of Incorporation of the Surviving Entity, except that as of the Effective Time, the Articles of Incorporation of the Surviving Corporation (Berlin Foundry Corporation) shall be amended in accordance with the Wisconsin Act, as follows:

The Articles of Incorporation shall be amended to reflect the change of the name of the Surviving Corporation by deleting the heading in its entirety and substituting in lieu thereof the following:

The Articles of Incorporation shall be amended to reflect the change of the name of the Surviving Corporation by deleting Article I in its entirety and substituting in lieu thereof the following:

(a) After the execution of this Plan of Merger, the Surviving Entity will submit Articles of Merger to the Indiana Secretary of State in accordance with the Indiana Act (“Indiana Articles”), and submit Articles of Merger with the Wisconsin Department of Financial Institutions, or other appropriate entity, in accordance with the Wisconsin Act (“Wisconsin Articles”). The Indiana Articles shall be filed with the Secretary of State of Indiana and the Wisconsin Articles with the Wisconsin Department of Financial Institutions (or other appropriate entity), at any time after the date hereof and shall be and become effective on July 1, 2005, at 8:00am (the “Effective Date”).

(b) The statutory merger provided for herein shall constitute a tax-free reorganization pursuant to the Internal Revenue Code of 1986, as amended.

(c) The Bylaws of the Corporation, as in effect immediately prior to the Effective Date, shall be the Bylaws of the Surviving Entity and shall continue in full force and effect until amended, changed or repealed as provided in the Articles of Incorporation and Bylaws of the Surviving Entity, and in the manner prescribed by the Wisconsin Act.

4. Manner and Basis of Converting Interest. The manner and basis of converting the shares in each corporation that is a party to the merger into shares of the Surviving Entity, and the mode of carrying the merger into effect are as follows:

(a) At the Effective Time, all of the shares of stock of HI-TECH issued and outstanding immediately prior to the Effective Time of the Merger, as well as all authorized stock, shall be completely retired and canceled by virtue of the merger and without any action of HI-TECH or the holder of any of its shares.

(b) At the Effective Time, all of the shares of stock of Iroquois issued and outstanding immediately prior to the Effective Time of the Merger, as well as all authorized stock, shall be completely retired and canceled by virtue of the merger and without any action of Iroquois or the holder of any of its shares.

(c) At the Effective Time, all of the shares of stock of Bohn issued and outstanding immediately prior to the Effective Time of the Merger, as well as all authorized stock, shall be completely retired and canceled by virtue of the merger and without any action of Bohn or the holder of any of its shares.

(d) Each issued and outstanding share of stock in the Corporation (of whatever class), as well as each authorized but unissued share of stock of the Corporation (of whatever class), will not be converted, exchanged or altered in any manner as a result of the Merger and will remain as stock of the Surviving Entity exactly as before the Merger, and the certificates which represented outstanding shares of stock of the Surviving Corporation prior to the Effective Date, without further action, shall continue to be and represent outstanding shares of stock of the Surviving Corporation thereafter without the issuance or exchange of new shares or share certificates. Each share of stock of the Surviving Entity outstanding immediately prior to the Effective Date of the Merger is to be an identical outstanding or treasury share of the Surviving Entity after the Effective Date of the Merger.

(e) Citation Corporation, a Delaware corporation (“Citation”) is the sole owner of all of the shares of stock in each of the Constituent Entities, and will be the sole owner of all shares of stock of the Surviving Entity after the Merger; accordingly, it is not necessary for Citation to receive shares of stock (or any other cash or property) in exchange for the cancellation of its shares in HI-TECH, Iroquois, or Bohn.

IN WITNESS WHEREOF, the undersigned has caused this Plan of Merger to be executed on this the 29^th day of June, 2005. This document was executed outside the State of Wisconsin.
