LATTICE ACQUISITION NOTES TO STATEMENTS OF REVENUE AND CERTAIN EXPENSES Year Ended December 31, 2003 and Nine Months Ended September 30, 2004 (Unaudited) (dollars in thousands) 1. Business and Summary of Significant Accounting Policies Business Lattice Communications, LLC and the company of which it is the sole member, LB Tower Company LLC ("LB Tower"; collectively, "Lattice"), are principally engaged in providing services to the wireless communications industry by leasing antenna sites on multi-tenant towers. Lattice leases tower space to a diverse range of wireless communications industries, including microwave, personal communications services, cellular, paging, mobile telephone, radio and television broadcasting, specialized mobile radio and enhanced specialized mobile radio. Lattice's communications sites are located throughout the United States. Lattice is jointly owned by Cinergy Telecommunications Holding Company, Inc. ("CT") - 43.5%; an investor partnership, Lattice Investors, L.P. - 43.5%; and, Lattice Partners, Ltd. ("LP") - 13%. LP is a limited liability company whose members include various officers and employees of Lattice. The majority of Lattice's related party transactions are conducted with The Cincinnati Gas & Electric Company and PSI Energy, Inc., under lease agreements assigned by their sister company, CT, to Lattice. On July 30, 2004, a definitive purchase agreement was signed by Pinnacle Towers Acquisition LLC, a wholly-owned subsidiary of Global Signal Inc. (the "Company"), to acquire from Lattice 220 owned towers and agreements relating to 15 other towers under management or lease. The purchase agreement and these Statements of Revenues and Certain Expenses exclude towers owned by LB Tower as well as certain assets of Lattice related to tower development. "Lattice Acquisition" represents the assets to be acquired by the Company. Basis of Presentation The accompanying statements of revenue and certain expenses were prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission for inclusion in a Form S-11 of the Company. The statements, which encompass the towers and agreements to be sold to the Company, are not representative of the actual operations of Lattice Acquisition for the periods presented or indicative of future operations, as they exclude the following: certain selling, general and administrative expenses; interest expense; and depreciation and amortization. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and such variances could be material. Revenue Recognition Revenues are recognized when earned. Escalation clauses present in lease agreements with Lattice's customers are recognized on a straight-line basis over the term of the lease. Concentration of Credit Risk Lattice Acquisition derives the largest portion of its revenues from customers who require wireless communications services. Excluding related parties, no single customer exceeded 10% of unrelated revenues in the year ended December 31, 2003 or the nine months ended September 30, 2004. 2.
