On December 7, 2011, PS Holdings and certain of its affiliates, on behalf of the Funds, entered into a $60.0 million term loan credit agreement with Pacific Sunwear (the “Term Loan”). Concurrently with and as a condition to entering into the Term Loan, Pacific Sunwear also issued 1,000 shares of Convertible Series B Preferred Stock, par value $0.01 (“the Series B Preferred”) to PS Holdings pursuant to a Stock Purchase and Investor Rights Agreement (the “Stock Purchase Agreement”) for an aggregate offering price of $100,000. Each share of Series B Preferred is convertible at any time prior to December 7, 2021 into Common Stock at a conversion rate of 13,473.537. In addition, in connection with the foregoing, PS Holdings is entitled to designate two directors to the board of directors of Pacific Sunwear.

as long as PS Holdings and its affiliates hold at least 33.33% of their initial equity investment in Pacific Sunwear, PS Holdings is entitled to designate one member of the board of directors of Pacific Sunwear.

The Reporting Persons intend to review continuously their equity interest in the Issuer. Depending upon their evaluation of the factors described below, one or more of the Reporting Persons may from time to time purchase additional securities of the Issuer, convert the Series B Preferred into Common Stock, dispose of all or a portion of the securities then held by such Reporting Persons, or cease buying or selling such securities; any such additional purchases or sales of securities of the Issuer may be in the open market, in privately negotiated transactions or otherwise.

The Reporting Persons may wish to engage in a constructive dialogue with officers, directors and other representatives of the Issuer, as well as the Issuer’s shareholders; topics of discussion may include, but are not limited to, the Issuer’s markets, operations, competitors, prospects, strategy, personnel, directors, ownership and capitalization. The Reporting Persons may also enter into confidentiality or similar agreements with the Issuer and, subject to such an agreement or otherwise, exchange information with the Issuer. The factors that the Reporting Persons may consider in evaluating their interest in the Issuer’s business include the following: (1) the Issuer’s business and prospects; (2) the performance of the Common Stock and the availability of the Common Stock for purchase at particular price levels; (3) the availability and nature of opportunities to dispose of the Reporting Persons’ interests; (4) general economic conditions; (5) stock market conditions; (6) other business and investment opportunities available to the Reporting Persons; and (7) other plans and requirements of the Reporting Persons.

Depending on their assessment of the foregoing factors, the Reporting Persons may, from time to time, modify their present intention as stated in this Item 4.

Except as set forth in this Schedule, the Reporting Persons intend to continuously review their options but do not have at this time any specific plans that would result in (a) the acquisition of additional securities of the Issuer or the disposition of securities of the Issuer; (b) any extraordinary corporate transactions such as a merger, reorganization or liquidation involving the Issuer or any of its subsidiaries; (c) any sale or transfer of a material amount of the assets of the Issuer or of any of its subsidiaries; (d) any change in the present management or board of directors of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the Issuer’s board of directors; (e) any material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer’s business or corporate structure; (g) any change in the Issuer’s charter or by-laws that may impede the acquisition of control of the Issuer by any person; (h) the Issuer’s Common Stock being delisted from a national securities exchange or ceasing to be authorized to be quoted in an inter-dealer quotation system or a registered national securities association; (i) causing a class of equity securities of the Issuer to become eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) any action similar to those enumerated above.

(a) – (b) In the aggregate, the Reporting Persons beneficially own, as of December 7, 2010, 13,473,537 shares of the Common Stock by virtue of the Series B Preferred directly held by PS Holdings. Such shares, if converted to Common Stock, represent 16.7% of the Issuer’s outstanding Common Stock. Each of PS Holdings, the Funds, Fund GP and Co-Invest GP have shared dispositive power with each other with respect to the Series B Preferred. Ultimate GP has sole dispositive power with respect to all of the Series B Preferred.

As a result of the relationships described in this Statement, each of the Reporting Persons may be deemed to beneficially own the Series B Preferred owned by PS Holdings. Neither the filing of this Statement nor any of its contents shall be deemed to constitute an admission by any Reporting Person, other than, solely with respect to the Series B Preferred acquired by PS Holdings, that it is the beneficial owner of any of the Series B Preferred referred to herein for purposes of the Act, or for any other purpose, and such beneficial ownership is expressly disclaimed.

(c) On December 7, 2011, PS Holdings and certain of its affiliates, on behalf of the Funds, entered into the Term Loan.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

On December 7, 2011, Pacific Sunwear and certain of its affiliates entered into the Term Loan with PS Holdings and certain of its affiliates.

Concurrently with and as a condition to entering into the Term Loan, Pacific Sunwear also issued 1,000 shares of the Series B Preferred to PS Holdings pursuant to the Stock Purchase Agreement for an aggregate offering price of $100,000. Each share of Series B Preferred is convertible at any time prior to December 7, 2021 into Common Stock at a conversion rate of 13,473.537. The Series B Preferred is convertible into shares of Common Stock at an initial exercise price of $1.75 per share of underlying Common Stock into which the Series B Preferred is converted. The Series B Preferred is entitled to voting rights and other rights up on liquidation. PS Holdings and certain permitted transferees are entitled to customary registration rights with respect to the Common Stock underlying the Series B Preferred.

In connection with the foregoing, PS Holdings is entitled to designate two directors to the board of directors of Pacific Sunwear. As long as PS Holdings and its affiliates hold at least 66.67% of their initial equity investment in Pacific Sunwear, PS Holdings is entitled to designate two directors of the board of directors of Pacific Sunwear, and as long as PS Holdings and its affiliates hold at least 33.33% of their initial equity investment in Pacific Sunwear, PS Holdings is entitled to designate one member of the board of directors of Pacific Sunwear.
