Re: Incentive Agreement

Dear Garry:

This letter agreement (“Letter Agreement”) shall serve as a formal and binding
commitment by Wolverine Tube, Inc. (“Company”) to offer you certain incentives
as outlined herein in exchange for your commitment to remain employed with the
Company and your agreement to add “Golden Dragon Precise Copper Tube Group” to
Appendix B of your 2002 Change-in-Control, Severance and Non-Competition
Agreement.

Reference is made to that certain letter agreement between you and the Company
dated March 11, 2007 (the “2007 Change-in-Control Payment Agreement”).

Under the 2007 Change-in-Control Payment Agreement, the Company agreed to pay
you a lump sum payment of One Hundred Twenty-five Thousand and no/100 Dollars
($125,000.00) (the “2007 Change-in-Control Payment”) in exchange for your
agreement to delay any right to receive the benefits described in Section
1(b)(i) (“the Change-in-Control Benefits”) of the 2002 Change-in Control,
Severance and Non-Competition Agreement you entered into with the Company on
July 12, 2002 (“the Change-in-Control Agreement”) until such right expires, as
it relates to the change in control of the Company that occurred on February 16,
2007.

According to the 2007 Change-in-Control Payment Agreement, if you terminate your
employment within two years from the date your right to exercise the
Change-in-Control Benefits expires, which is February 16, 2009, and seek the
Change-in-Control Benefits; and/or otherwise exercise your rights under the
Change-in-Control Agreement, including but not limited to resignation with Good
Reason as defined in Section 1(a)(iii) therein, you are obligated to immediately
return the 2007 Change-in-Control Payment to the Company, together with six
percent (6%) interest per annum.

By this Letter Agreement, the Company agrees to extend the date by which you may
exercise your right to the Change-in-Control Benefits until February 16, 2010.
Please note that you will remain obligated to return the 2007 Change-in-Control
Payment of $125,000, together with six percent (6%) interest per annum, if you
elect to exercise your right to the Change-in-Control Benefits and/or otherwise
exercise your rights under the Change-in-Control Agreement prior to February 16,
2009.

 
In addition, effective September 8, 2008, the Company will increase your
annualized salary from $212,000 to $232,000.
