In its April 19, 2015 report, ISS recognized the significant and numerous positive changes that had already occurred at Superior and noted that there appeared to have been a "sweeping revival of the company." In particular, ISS took note of the numerous "positive steps" that the Superior Board has taken to improve Superior's corporate governance practices, referencing the following corporate governance practices that are now in effect at Superior: (i) the positions of Chairman of the Board and CEO are held by separate individuals and the Chairman of Superior's Board is an independent director; (ii) Superior has completely phased out its Board's classified structure, with all directors standing for election at the 2015
Annual Meeting for a one-year term; (iii) shareholders have the right to call special meetings with only a
10% ownership threshold and no material restrictions on the exercise of such right; (iv) no shareholder rights plan or poison pill is in effect; and (v) a clawback policy applicable to all executive officers is
currently in effect.
ISS also took note of the efforts of the Superior Board to enhance its board composition, an effort that began approximately four years ago, and the sea change in Superior's corporate governance that led to Superior's transition from being a family-led (but still publicly-held firm) to a public company today overseen by a truly independent board of directors fully accountable to shareholders. Of the seven

DB1/ 83118549.5

nominees being recommended by the Superior Board, all have joined the Board since 2007 and more than half have joined the Board since 2013 (Margaret S. Dano and Francisco S. Uranga joined in 2007, Timothy C. McQuay joined in 2011, James S. McElya joined in 2013 and Jack A. Hockema, Paul J. Humphries and Donald J. Stebbins joined in 2014). Philip Coburn, who has been a member of the Superior Board since 1990, is retiring from the Board and will not stand for re-election this year. As ISS noted, "[f]our of the current board members have a tenure of less than 16 months, which speaks to its attempts to remake the company and freshen its own ranks."
In its report, ISS also recognized as positive the actions that the Superior Board has taken to evolve Superior into a more efficient global competitor, enhance Superior's long-term prospects and build on the strong brand and automotive industry reputation that was established by Louis and Steven Borick over more than fifty years. These actions have included (i) launching on-time and on-budget, in the fourth quarter of 2014, a new modern aluminum wheel manufacturing facility in Chihuahua, Mexico that will leverage Superior's demonstrated operating success in Mexico, lower Superior's overall manufacturing costs and improve Superior's position in a highly competitive market; (ii) closing Superior's Rogers, Arkansas aluminum wheel manufacturing facility and shifting production to other more cost-efficient manufacturing facilities, including Superior's newest facility in Chihuahua, Mexico; (iii) lowering Superior's overall cost base as part of a long-term, managed strategy to be more competitive; and (iv) focusing more closely on measures of operating efficiency which help Superior control cost-of-quality issues and optimize its capital spending in what remains a very capital intensive business. In this regard, ISS noted as follows:

"The closing of the Arkansas plant was clearly an effort to cut costs - but also part of a long- term, managed strategy to lower the overall cost base, not a stopgap measure implemented by a company in crisis."

"This evidence of both a long-term perspective and the successful implementation of key initiatives includes the investment in the Mexico plant, the increase in temporary workers from 3 percent to 25 percent (which helps transform fixed labor cost to variable labor cost at the margin), and things like increased attention to measures of operating efficiency which help the company control cost-of-quality issues and optimize its capital spending in what remains a very capital intensive business."

ISS also took note of the efforts that the Superior Board has made to return value to Superior's shareholders through cash dividends and stock repurchases, noting that over the past two years Superior had increased its dividend and repurchased approximately 9.5% of its outstanding shares. In 2014, Superior returned to shareholders over $40 million through dividend payments and share repurchases and, over the past five years, Superior has returned to shareholders over $134 million in dividends and stock repurchases, equal to almost $5 per share. As previously announced, in October 2014, the Superior Board authorized a $30 million stock repurchase program, after Superior completed a $30 million stock repurchase program in 2014 that was authorized in 2013.
Unlike in the past two years, this year GAMCO has decided to target specific members of the Superior Board - Paul J. Humphries, Timothy C. McQuay and Francisco S. Uranga, three highly qualified and extremely valued members of the Superior Board who bring to the Superior Board perspectives, insights, experiences and competencies that are central to the pursuit of Superior's strategic priorities and its efforts to transform itself into a stronger, more efficient global competitor. Commenting on the decision of GAMCO to target specific members of the Superior Board, ISS noted the following.
"GAMCO is targeting board members Humphries, McQuay, and Uranga. Humphries, however, has only been on the board for 8 months, and McQuay for a little more than 3 years; if the charge

DB1/ 83118549.5

is long-term board entrenchment and not having 'skin in the game' from a stock ownership standpoint, it makes little sense to target two of the newest members of the board, whose tenure has been marked by rapid improvements in corporate governance and increasing signals of board accountability. These directors themselves, one might consider, are themselves part of the rapid improvement."

Commenting on the ISS report, Superior issued the following statement: "We are very pleased that ISS, one of the leading independent, third-party proxy advisory firms, has carefully reviewed the voting alternatives and has recommended that shareholders vote for all seven of Superior's director nominees on the WHITEproxy card. As we have stated consistently, we do not believe that any of GAMCO's nominees can be said to have experience comparable to that of any of the three highly qualified and very experienced members of the Superior Board that GAMCO is seeking to replace. As was the case with GAMCO's previous two unsuccessful proxy contests against Superior, not one of GAMCO's nominees has any executive-level manufacturing, automotive industry, supply chain management, global markets or global operations experience, and we do not believe that any of GAMCO's nominees would bring to Superior's Board any relevant insights, perspectives, skills or competencies not already present among the current members of the Superior Board. In addition, none of GAMCO's nominees have any experience navigating a company the size and global reach of Superior through the complex, dynamic and highly competitive global business environment in which we operate."

Superior is being advised in connection with the proxy contest by Winston & Strawn, LLP and Morgan, Lewis & Bockius LLP. Mackenzie Partners, Inc. is serving as Superior's proxy solicitor.
