Item 4.

Purpose of Transaction.

The Reporting Persons purchased the Shares based on each of the Reporting Persons’ respective belief that the Shares, when purchased, represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavour to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

On March 4, 2013, Quinpario, on behalf of the Reporting Persons (collectively, the “Quinpario Group”), delivered a letter to the Issuer’s Chairman and CEO, Zsolt Rumy, a copy of which is attached hereto as Exhibit 99.1 and is incorporated herein by reference, in order to solicit the Issuer’s cooperation in working with Quinpario to create long-term, sustainable shareholder value for all shareholders of the Issuer. In the letter, Quinpario stated that it has been following the Issuer closely for some time and has devoted considerable time and resources to analyzing the Issuer’s product offerings, operational performance and corporate structure, as well as the competitive environment in the carbon fiber space. The letter reported that the Quinpario Group’s substantial investment in the Issuer is based upon extensive due diligence, which has led Quinpario to conclude that the Issuer is failing to deliver fully on its potential. As such, Quinpario believes that an opportunity exists to dramatically improve the Issuer’s operational performance, unlock the Issuer’s significant growth potential and enhance shareholder value.

By way of background, the letter noted that Quinpario is an investment and operating company founded by former senior executives of Solutia, Inc. The letter further described how these senior executives were able to successfully transform Solutia from a domestic commodity chemical company to a pure-play global specialty player with world-leading market positions across automotive, aviation, energy, construction and a host of other related industries. In doing so, these senior executives were able to create substantial value for shareholders of Solutia.

CUSIP NO. 98975W104

The letter noted that Quinpario’ analysis of the carbon fiber industry, generally, and the Issuer, specifically, has confirmed that the Issuer has exceptional technology, product offerings and a strong customer base in the wind and aircraft brake markets, but has yet to realize the full potential consistent with its strong technical capabilities. Quinpario stated that there exists, therefore, a unique and compelling opportunity for Quinpario to work together with the Issuer in key areas in order to accelerate global growth, market penetration, application development and improved financial performance across the Issuer’s existing and targeted markets.

Quinpario noted in the letter that it has previously attempted to engage in meaningful discussions with the Board regarding strategic alternatives to maximize shareholder value. In a letter to Mr. Rumy and the Board in November 2012, Quinpario outlined two strategic alternatives that it believed would create substantial value for all shareholders: (i) an acquisition by Quinpario of all of the outstanding shares of the Issuer at a price per share in the mid-teens; or (ii) a recapitalization whereby Quinpario would make an equity investment in the Issuer that, along with a new credit facility, would fund a sizeable special cash dividend, thereby providing existing shareholders immediate monetization and an opportunity to participate in the future upside of the Issuer. Quinpario was disappointed that the only response it received was in the form of a letter from the Issuer’s legal counsel, who indicated that Quinpario’ letter and interest had only been “informally” shared with the other members of the Board and that the Issuer was unwilling to engage with Quinpario. Quinpario found this response troubling given the substantial value to shareholders offered by each of Quinpario’ proposed alternatives.

The letter stated that Quinpario has continued to closely monitor developments at the Issuer, with an eye towards the Issuer’s strategic execution, operational and financial performance and share price performance. Quinpario stated that over the past several months, it has become even more apparent that the Issuer is underperforming and that a significant opportunity exists to dramatically improve operational performance and enhance shareholder value. Quinpario stated that Issuer’s recent presentation at the annual meeting brought this fact into even clearer focus as the Issuer’s analysis of where the Issuer is today, compared to 2008, seemed misguided at best. Quinpario noted that Mr. Rumy, like many other shareholders, must be frustrated by the fact that no shareholder value has been created over the past several years, and stated that this lack of value creation rests squarely with the underperformance of the business and is not due to misinformed analysts or short-sellers, as the Issuer would have the investment community believe.

Quinpario noted in the letter that despite five years of heavy investment in capacity expansion and operational improvements, the Issuer’s operational performance continues to stagnate, as evidenced by (i) flat revenue and operating income and (ii) deteriorating gross profit and cash from operations. Quinpario stated in the letter it believes that this severe underperformance appears to be largely due to (i) heavy investment of capital without adequate financial returns, (ii) unsuccessful execution on the Issuer’s strategic plan for new market and application development, (iii) the Issuer’s failure to diversify operations or exploit new market opportunities, (iv) the Issuer’s unrealistically upbeat assessment of its operational performance and continued failure to meet street expectations, and (v) the failure to develop a globally-oriented organization to take the Issuer to the next level. It is therefore not surprising, according to Quinpario, that during this same time period, and virtually over any time period, the Issuer’s share price has dramatically underperformed both the S&P 500 market index and its publicly-traded carbon fiber peers.

Despite all of this, Quinpario stated that it continues to strongly believe in the long-term prospects of the Issuer’s business and its significant growth potential. Quinpario stated that the Issuer is to be commended for its development of the wind and aircraft brake markets and the strong relationships it has built with its important and valued customers in those segments. However, Quinpario noted, if the Issuer remains committed to the status quo, then the window of opportunity will quickly close as others usurp the Issuer’s valuable market position and its rightful role in the carbon fiber market. Quinpario stated that allowing this to occur would be a disservice to the Issuer’s employees and shareholders and an inappropriate legacy for what Mr. Rumy has created.

CUSIP NO. 98975W104

Quinpario stated it is concerned that not enough is being done to take appropriate actions to address the Issuer’s troubled performance. Quinpario stated it is even more concerned that the Board was not even willing to formally consider viable strategic options upon presentation last year and that the Issuer’s “just say no” approach is not in the best interests of its shareholders. In order to address this issue, Quinpario stated it believes that significant and immediate change is required at the Issuer. To that end, Quinpario stated it has assembled a highly competent and reputable group of shareholders and director candidates, who collectively have (i) deep expertise in dealing with complex financial and operational issues and managing companies in a global environment, (ii) a deep understanding of the commercial process, and (iii) a proven track record of creating shareholder value. Quinpario reiterated its belief that its team at Quinpario and the members of the Quinpario Group can play a valuable role in helping the Issuer to realize its potential as a leading global performance materials and composite company. On the other hand, Quinpario stated that left to its own devices, the Issuer will continue to pursue a status quo that has failed to grow the Issuer’s business and create shareholder value.

Quinpario stated that in order to ensure that the shareholders have an opportunity to decide for themselves whether the involvement of Quinpario at the Issuer would be welcome and beneficial in terms of capitalizing on growth opportunities and enhancing the value of their investment, and due to the peculiarities of Missouri law and the Issuer’s governance documents, Quinpario has delivered a letter to the Issuer, a copy of which is enclosed herewith, requesting a special meeting of shareholders (the “Special Meeting”) in accordance with Section 2.02 of the Restated Bylaws (the “Bylaws”) for the following purposes:

(i)

to remove, without cause, all of the directors serving on the Board; and

(ii)

to elect the Quinpario Group’s highly-qualified director candidates, Jeffry N. Quinn, Edgar G. Hotard, Walter Thomas Jagodinski, James P. Heffernan, and Dr. John Rutledge, to the Board to fill the resulting vacancies that would exist in the event that some or all of the current directors are successfully removed.

A copy of the letter requesting that the Issuer call the Special Meeting is attached hereto as Exhibit 99.2 and is incorporated herein by reference.

Quinpario stated it would be willing, perhaps, to defer the calling of the Special Meeting if the Board were to immediately agree to engage in good-faith discussions with Quinpario regarding Board representation and its willingness to work with the Quinpario Group to consider strategic alternatives to enhance shareholder value, including a consideration of a potential renewal of the two alternatives previously proposed to the Issuer by Quinpario.

Quinpario concluded by stating that it strongly believes that the Issuer has successfully established industry-leading technical capability, but has significantly underperformed both commercially and financially. Quinpario stated that unless these shortcomings are immediately addressed, it believes there is little prospect for the Issuer’s share price to achieve meaningful and sustained appreciation. The Issuer’s share price has underperformed over almost any reasonable measurement period, and Quinpario believes it is time for the Board to take immediate action to address this issue. Quinpario looks forward to working with Mr. Rumy, senior management, and the Board to address the challenges and opportunities facing the Issuer, and to ensure that the Issuer is run in a manner consistent with the best interests of all its shareholders.

CUSIP NO. 98975W104

In addition to the letter, Quinpario delivered to the Board a copy of a presentation that candidly sets forth in further detail the analysis performed by Quinpario that demonstrates the deterioration in the Issuer’s financial performance and the opportunities that exist to unlock significant value for the benefit of all shareholders. A copy of the presentation is attached hereto as Exhibit 99.3 and is incorporated herein by reference.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon completion of any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, continuing to engage in communications with management, the Board and the shareholders of the Issuer, regarding the nominations in connection with the Special Meeting and the composition of the Board, generally, and engaging in discussions with third parties about the Issuer and the Reporting Persons’ investment, making proposals to the Issuer concerning strategic alternatives, changes to the capitalization, ownership structure, board structure or operations of the Issuer, purchasing additional Shares, selling some or all of their Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, or changing their intention with respect to any and all matters referred to in Item 4.
