Gidel ("Gidel"), Fortress Investment Fund LLC ("FIF"), Fortress Fund MM LLC ("FFMM"), FIT GSL LLC ("FIT GSL"), Fortress Investment Trust II ("FIT II"), Fortress Investment Fund II ("FIF II"), Fortress Fund MM II LLC ("FFMMII"), Fortress Investment Group LLC ("FIG"), and Fortress Investment Holdings LLC ("FIH" and together with FRIT PINN, FRIT, FPIF, FIGA, Gidel, FIF, FFMM, FIT GSL, FIT II, FIF II, FFMMII, FIG, the "Reporting Persons") with respect to the shares of common stock, par value $0.01 per share (the "Common Stock"), of Global Signal Inc., a Delaware corporation (the "Issuer"). All capitalized terms used in this Amendment and not otherwise defined herein have the meanings assigned to such terms in the Schedule 13D. Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer. FRIT has replaced the Credit Agreement, dated as of December 21, 2004, between FRIT PINN and Bank of America, N.A., Morgan Stanley Asset Funding Inc., the other lenders that may become parties thereto and Banc of America Securities LLC (the "Old Credit Agreement"), with the FRIT Credit Agreement discussed below. No shares of the Issuer's Common Stock remain pledged under the Old Credit Agreement. FRIT entered into a credit agreement, dated as of December 9, 2005, with Deutsche Bank AG, London Branch and the other lenders that may become parties thereto (the "FRIT Credit Agreement"). Pursuant to the FRIT Credit Agreement, FRIT borrowed $464.4 million from the lenders thereunder and this amount is secured by a pledge of a total of 19,659,324 shares of the Issuer's Common Stock, consisting of a pledge by FRIT of a total of 497,076 shares owned by FRIT and a pledge by FRIT PINN of a total of 19,162,248 shares owned by FRIT PINN. The term of the FRIT Credit Agreement is 12 months with a six-month extension at the option of the lenders. The 19,659,324 shares of Common Stock represents approximately 28.6% of the Issuer's issued and outstanding Common Stock as of November 4, 2005. In addition, FIT II entered into a credit agreement, dated as of December 9, 2005, with Deutsche Bank AG, London Branch and the other lenders that may become parties thereto (the "FIT II Credit Agreement", and together with the FRIT Credit Agreement, the "New Credit Agreements"). Pursuant to the FIT II Credit Agreement, FIT II borrowed $228.3 million from the lenders thereunder and this amount is secured by a pledge by FIT GSL of a total of 4,705,883 shares of the Issuer's Common Stock owned by FIT GSL. The term of the FIT II Credit Agreement is 12 months with a six-month extension at the option of the lenders. The 4,705,883 shares of Common Stock represents approximately 6.9% of the Issuer's issued and outstanding Common Stock as of November 4, 2005. The New Credit Agreements contain representations, covenants and default provisions relating to FRIT, FRIT PINN, FIT II, FIT GSL, and the Issuer, and also require prepayment of a portion of the borrowings by FRIT and FIT II in the event the trading price of the Issuer's Common Stock decreases below certain specified levels. In the event of a default under the New Credit Agreements by FRIT or FIT II, the lenders may foreclose upon any and all shares of Common Stock pledged to them. FRIT and FIT II have agreed in the New Credit Agreements that if a shelf registration statement is not effective and usable for resales of any portion of the pledged common stock by the lenders or their assignees (in the event of foreclosure) as of March 9, 2006, FRIT or FIT II, as applicable, will prepay a related portion of their borrowings. Except as provided in the Amended and Restated Investor Agreement, the Option Agreement, the Credit Agreements or as set forth herein, neither any of the Reporting Persons nor, to the best of such Reporting Persons' knowledge, any of the Covered Persons has any contracts, arrangements, understandings or relationships (legal or otherwise), with any person with respect to any securities of the Issuer, including, but not limited to, transfer or voting of any securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or losses, or the giving or withholding of proxies.
