HONEYWELL TRAFFIC ALERT & COLLISION AVOIDANCE SYSTEM BUSINESS NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS (IN THOUSANDS) 1. BACKGROUND AND DESCRIPTION OF BUSINESS The Honeywell Traffic Alert and Collision Avoidance System product line (the "TCAS Business"), a leader in avionics safety systems, produces and develops airborne collision avoidance systems of which approximately 6,500 units have been installed in commercial, corporate and military aircraft. The systems reduce the potential for mid-air collisions and so-called near-miss incidents among aircraft. The systems help prevent accidents by displaying to the flight crew the position of surrounding aircraft and, when necessary, providing both visual and audible warnings and maneuvering instructions and provide an independent and complementary supplement to the air traffic control system. The TCAS business headquarters and principal operations are located in Phoenix, Arizona. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICES BASIS OF PRESENTATION AND USE OF ESTIMATES The TCAS Business unit was an integrated business unit of Honeywell Inc. ("Honeywell"). The accompanying financial statements reflect the TCAS Business assets, liabilities and operations, which have been derived from Honeywell's historical financial statements and accounting records. As an integrated business unit, prior to December 31, 1999, Honeywell did not maintain separate accounts receivable and inventory records for the TCAS Business, nor did it allocate any such balances to the TCAS Business. All significant intercompany accounts and transactions have been eliminated. The TCAS Business operations, as presented herein include significant allocations and estimates of expenses of Honeywell based upon estimates of services performed by Honeywell, which management of the TCAS Business believes are reasonable. Such services include manufacturing support, treasury, cash management, employee benefits, taxes, risk management, internal audit and general corporate services. Accordingly, the financial position results of operations and cash flows as presented herein may not be the same as if the TCAS Business had been an independent, stand alone entity. The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires the TCAS Business management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The most significant of these estimates and assumptions relate to cost allocations from Honeywell, cost in excess of net assets acquired, income taxes, litigation and environmental obligations, warranty reserves, pension estimates and recoverability of recorded amounts of fixed assets. Actual results could differ from these estimates. The accompanying financial statements have been prepared in accordance with the accounting principles applicable to interim financial statements and the rules of the Security and Exchange Commission, and accordingly may not include all disclosures required by accounting principles generally accepted in the United States of America. These financial statements are unaudited but in the opinion of management reflect all adjustments, consistent of normal recurring adjustments required for a fair presentation. 3. TRANSACTIONS WITH HONEYWELL The TCAS Business relies on Honeywell for certain services, including manufacturing support, treasury, purchasing, procurement of inventories, cash management, employee benefits, taxes, risk management, internal audit, fixed asset systems support, payroll processing, mainframe and PC processing and support services, and general corporate services. Although certain assets, liabilities and expenses related to these services have been allocated to the TCAS Business, the combined financial position, results of operations and cash flows presented in the accompanying financial statements would not be the same as if the TCAS Business had been an independent, stand alone entity.

INVENTORIES MARCH 31, 2000 ---------- Raw materials ........... $ 6,845 Work in process ......... 2,422 Finished goods .......... 3,104 ------- Total .................. $12,371 ======= 5. COMMITMENTS AND CONTINGENCIES The TCAS Business is periodically subject to litigation, claims or assessments and various contingent liabilities (including environmental matters) incidental to its business. With respect to those investigative actions, items of litigation, claims or assessments of which they are aware, management of the TCAS Business is of the opinion that the probability is remote that, after taking into account certain provisions that have been made with respect to these matters, the ultimate resolution of any such investigative actions, items of litigation, claims or assessments will have a material adverse effect on the financial position, cash flows or results of operations of the TCAS Business. 6. INVESTED EQUITY Invested equity represents the equity contributed to the TCAS Business by Honeywell, advances to or from affiliates, and the accumulated results of operations of the TCAS Business.
