Mr. Small has also been appointed by the Board as a member of the Company’s audit and compensation committees. Mr. Small’s appointments have been made in recognition of his investment experience, as well as his previous involvement in the aerospace industry. The filing of this Schedule is not an admission by the Reporting Persons that they hold shares for the purpose or with the effect of changing or influencing the control of the Issuer.
Except as set forth above, the Reporting Persons have no plans or proposals which relate to or would result in any of the actions enumerated in clauses (a)-(j) of Item 4 of Schedule 13D under the Act, as amended.
Item 5. Interest in Securities of Issuer.
(a) and (b)
The beneficial ownership of Common Stock by each person named in Item 2 above is as follows:
Fund VII directly holds 3,406,694 shares of Common Stock. Accordingly, Fund VII has sole voting and dispositive power with respect to 3,406,694 shares of Common Stock. Based on the immediately preceding sentence, as the sole general partner of Fund VII, 7BA may be deemed to beneficially own 3,406,694 shares of Common Stock held by Fund VII. However, 7BA disclaims beneficial ownership of such shares of Common Stock and the filing of this Statement shall not be construed as an admission that 7BA is, for the purpose of Section 13(d)(3) of the Act, the beneficial owner of such shares held by Fund VII.
Fund VII-A directly holds 636,891 shares of Common Stock. Accordingly, Fund VII-A has sole voting and dispositive power with respect to 636,891 shares of Common Stock. Based on the immediately preceding sentence, as the sole general partner of Fund VII-A, 7BA may be deemed to beneficially own 636,891 shares of Common Stock held by Fund VII-A. However, 7BA disclaims beneficial ownership of such shares of Common Stock and the filing of this Statement shall not be construed as an admission that 7BA is, for the purpose of Section 13(d)(3) of the Act, the beneficial owner of such shares held by Fund VII-A.
Berkshire Partners and the Funds acknowledge that they are part of a “group” for purposes of Section 13(d)(3). Collectively, the Funds directly hold 4,043,585 shares of Common Stock. Based on the two preceding sentences, Berkshire Partners may be deemed to beneficially own 4,043,585 shares of Common Stock held by the Funds. However, Berkshire Partners disclaims beneficial ownership of such shares of Common Stock and the filing of this Statement shall not be construed as an admission that Berkshire Partners is, for the purpose of Section 13(d)(3) of the Act, the beneficial owner of such shares held by the Funds.

Investors owns 67,357 shares of Common Stock. Accordingly, Investors has sole voting and dispositive power with respect to 67,357 shares of Common Stock.
Investors III owns 17,090 shares of Common Stock. Accordingly, Investors III has sole voting power and dispositive power with respect to 17,090 shares of Common Stock.
SF directly holds 55,530 shares of Common Stock. Accordingly, SF has sole voting and dispositive power with respect to 55,530 shares of Common Stock. Based on the immediately preceding sentence, as the sole general partner of SF, SA may be deemed to beneficially own 55,530 shares of Common Stock held by SF. However, SA disclaims beneficial ownership of such shares of Common Stock and the filing of this Statement shall not be construed as an admission that SA is, for the purpose of Section 13(d)(3) of the Act, the beneficial owner of such shares held by SF.
SP manages investments for its clients and has limited discretionary voting power in respect of Common Stock. SP owns 103,500 shares of Common Stock over which it shares voting power and has full dispositive power.
By virtue of their positions as managing members of 7BA, Investors, Investors III, SA and Berkshire Partners, the Berkshire Principals may be deemed to possess indirect beneficial ownership of the shares of Common Stock beneficially owned by Fund VII, Fund VII-A, Investors, Investors III and SF. However, none of the Berkshire Principals, acting alone, has voting or investment power with respect to shares beneficially owned by Fund VII, Fund VII-A, Investors, Investors III or SF, and, as a result, each Berkshire Principal disclaims beneficial ownership of such shares of Common Stock.
Two of the Berkshire Principals beneficially own shares of Common Stock. Robert J. Small owns 5,000 shares of Common Stock and Ross M. Jones is a trustee of a foundation that owns 4,000 shares of Common Stock. Accordingly, Robert J. Small has sole voting and dispositive power with respect to 5,000 shares of Common Stock and Ross M. Jones has shared voting and shared dispositive power with respect to 4,000 shares of Common Stock.
Pursuant to the Company’s Quarterly Report on Form 10-Q for the period ended January 2, 2010, there were 49,029,140 shares of Common Stock issued and outstanding as of January 29, 2010. Accordingly, the shares of Common Stock beneficially owned by the Reporting Persons, in the aggregate, represent approximately 8.74% of the outstanding shares of Common Stock, which is broken out by Reporting Person as follows:
  (i)   Fund VII beneficially owns 6.95% of the Issuer’s Common Stock.
 
  (ii)   Fund VII-A beneficially owns 1.30% of the Issuer’s Common Stock.
 
  (iii)   Investors beneficially owns 0.14% of the Issuer’s Common Stock.
 
  (iv)   Investors III beneficially owns 0.03% of the Issuer’s Common Stock.
 
  (v)   SF beneficially owns 0.11% of the Issuer’s Common Stock.
 
  (vi)   SP beneficially owns 0.21% of the Issuer’s Common Stock.
By virtue of the relationships described herein, the Reporting Persons may be deemed to constitute a “group” within the meaning of Rule 13d-5 under the Act. As a member of a group, each Reporting Person may be deemed to share voting and dispositive power with respect to, and therefore beneficially own, the shares beneficially owned by members of the group as a whole. The filing of this Statement shall not be construed as an admission that the Reporting Persons beneficially own those shares held by any other members of the group. Berkshire Partners, the Funds and 7BA acknowledge that they are part of a “group” for purposes of Section 13(d)(3). However, the filing of this Statement shall not be construed as an admission that Investors, Investors III, SF, SA or SP are a part of a group, or have agreed to act as a part of a group.
