ABOUT HONEYWELL Honeywell, a Delaware corporation, is a diversified technology and manufacturing leader, serving customers worldwide with aerospace products and services; control technologies for buildings, homes and industry; automotive products; power generation systems; specialty chemicals; fibers; plastics; and electronic and advanced materials. We employ approximately 120,000 people in 95 countries. OUR BUSINESS We aggregate our strategic business units into four reportable segments: AEROSPACE SOLUTIONS. Our Aerospace Solutions segment is a customer-driven global provider of integrated avionics, engines, systems and service solutions for aircraft manufacturers, airlines, business and general aviation, military and airport operations. Our aerospace products can be found on virtually every type of aircraft in use, in nearly every region of the world. Major product categories for Aerospace Solutions include: Avionics systems and equipment for communication, navigation and safety Aircraft systems and components including auxiliary power units, environmental controls, aircraft lighting and integrated landing systems Propulsion systems including turboprop and turbofan engines for business and regional aircraft and helicopters Launch and satellite vehicle systems including inertial and global positioning systems, guidance systems, satellite positioning and stabilization systems, and launch vehicle controls Airport systems including satellite landing systems, airport lighting, ground vehicle management and maintenance systems In addition to our aerospace products, we offer a wide range of value-added services, including: Comprehensive maintenance and support for all our products A large portfolio of spare parts and consumable hardware Inventory management Logistics and process support Technical publications Ground support equipment Training Our Aerospace Solutions sales in 1999 were $9,908 million or basically flat compared with 1998. Sales of avionics products were higher due principally to continued strong demand for flight safety products such as collision avoidance and enhanced ground proximity warning systems. Sales to the aftermarket, particularly repair and overhaul and the military, were also higher. The acquisition of a controlling interest in the Normalair-Garrett Ltd. environmental controls joint venture in the prior year also increased sales in 1999. This increase was offset by lower sales to commercial air transport and military original equipment manufacturers, and the effects of divestitures and a restructuring of a government technical services contract. Our Aerospace Solutions segment profit for 1999 was $1,918 million, an increase of $331 million, or 21 percent compared with 1998. The increase principally resulted from improved sales of higher-margin aftermarket and avionics products and cost structure improvements primarily from census and benefit cost reductions. AUTOMATION & ASSET MANAGEMENT. Our Automation & Asset Management segment is comprised of two strategic business units: Home and Building Control and Industrial Control. S-4

Home and Building Control provides products and services to create efficient, safe, comfortable environments. This unit offers: Controls for heating, ventilating, humidification and air-conditioning equipment Security and fire alarm systems Home comfort products and integration systems Energy-efficient lighting controls Building management systems and services In February 2000, our Home and Building Control business acquired Pittway Corporation, one of the world's leading manufacturers and distributors of security and fire systems and low-voltage products for homes and buildings. Pittway had 1999 sales of $1.6 billion. See 'Recent Developments'. Industrial Control is the world's leading supplier of industrial control systems and related advanced software solutions and products. The mission of the Industrial Control unit is to improve our customers' competitiveness through the application of sensing and control technologies. Our Automation & Asset Management sales in 1999 were $6,115 million, an increase of $158 million, or 3 percent compared with 1998. Sales were higher for the Home and Building Control business driven by growth in control and consumer products and building services and security. Acquisitions also contributed to the sales increase. Lower sales from the energy retrofit and installed systems businesses were a partial offset. Sales for the Industrial Control business were basically flat compared with the prior year. Higher sales due to acquisitions and growth in the sensing and control business were offset by the effects of continued weakness in the pulp and paper and refining markets. Sales for the segment were also negatively impacted by foreign currency fluctuations due to the strong dollar. Our Automation & Asset Management segment profit in 1999 was $767 million, an increase of $62 million, or 9 percent compared with 1998. Segment profit for the Home and Building Control business was up significantly due to improvement in the control products business and the exiting of the lower-margin energy retrofit and installed systems businesses. Cost savings from census reductions also contributed to the improvement. This increase was offset somewhat by lower segment profit for the Industrial Control business as growth in the higher-margin sensing and control business and cost structure improvements were more than offset by the effects of continued weakness in the pulp and paper and refining markets. PERFORMANCE MATERIALS. Our Performance Materials segment is comprised of three strategic business units: Electronic Materials, Specialty Chemicals and Performance Polymers. Electronic Materials is a leading provider of: Materials and solutions used in wafer fabrication Specialty electronic materials such as amorphous alloy products, copper foils, and advanced polymers Advanced packaging substrates for silicon chips Printed circuit boards Electronic manufacturing services Specialty Chemicals is a leading global manufacturer of specialty and fine chemicals for a broad range of markets. We provide tailored customer solutions worldwide through the Chemical Specialties, Fluorine Products, Pharmaceutical Fine Chemicals, Specialty Wax and Additives businesses that make up our Specialty Chemicals strategic business unit. Performance Polymers is a world leader in the production of nylon, polyester, polyethylene, fluoropolymer and other chemicals used in engineered plastics, specialty films, performance fibers and carpet fibers. S-5

Our Performance Materials sales in 1999 were $4,007 million, a decrease of $162 million, or 4 percent compared with 1998 due principally to divestitures including the environmental catalyst, Laminate Systems and phenol businesses. Lower sales for carpet fibers also contributed to the decrease. Higher sales for specialty films, engineering plastics and waxes were a partial offset. Higher sales from the acquisitions of Johnson Matthey Electronics, a supplier of wafer fabrication materials and interconnect products to the electronics and telecommunications industries, and Pharmaceutical Fine Chemicals, a supplier of active and intermediate pharmaceutical chemicals, were also a partial offset. Our Performance Materials segment profit in 1999 was $439 million, a decrease of $195 million, or 31 percent compared with 1998. The decrease principally reflects the effects of the continuing pricing pressures in the Performance Polymers and Electronic Materials businesses and higher raw material costs in certain Performance Polymers businesses. The impact of prior year divestitures also contributed to the decrease. The effect of improved sales volume for specialty films, engineering plastics and waxes was a partial offset. POWER & TRANSPORTATION PRODUCTS. Our Power & Transportation Products segment is comprised of three strategic business units: Transportation and Power Systems, Consumer Products Group and Friction Materials. This segment's key areas of business include automotive and truck products, engine boosting systems and on-site power generation. Its products include: Garrett'r' turbochargers and charge air coolers Bendix'r' air brakes, compressors, air dryers, disk brake pads and drum brake linings JURID'TM' & RoadTuff'r' friction material FRAM'r' filters Autolite'r' spark plugs Prestone'r' and Holts'r' car care products Parallon'TM' 75 TurboGenerator Simoniz'r' appearance products (outside North America) Our Power & Transportation Products sales in 1999 were $3,581 million, an increase of $194 million, or 6 percent compared with 1998. Sales for the Transportation and Power Systems business were significantly higher driven by strong growth for the turbocharging systems business due primarily to continued strong sales in Europe reflecting the turbodiesel's increased penetration of the passenger car market. Sales for our Commercial Vehicle Systems business, which is part of Transportation and Power Systems, increased due principally to increased North American truck builds. Sales for the Consumer Products Group business also increased, led by higher sales of Prestone'r' products and FRAM'r' filters. Lower sales for the Friction Materials business due to pricing pressures and weakness in the European market were a partial offset. Sales were also negatively impacted by foreign currency fluctuations due to the strong dollar. Our Power & Transportation Products segment profit in 1999 was $322 million, an increase of $88 million, or 38 percent compared with 1998. The increase reflects higher sales for the Transportation and Power Systems and Consumer Products Group businesses. Cost structure improvements in these businesses resulting from Six Sigma initiatives, materials procurement savings and census reductions also contributed to the increase. MERGER OF ALLIEDSIGNAL INC. AND HONEYWELL INC. On December 1, 1999, AlliedSignal Inc. and Honeywell Inc. combined to create Honeywell International Inc. On that date, AlliedSignal Inc. changed its name to Honeywell International Inc. and a wholly-owned subsidiary of Honeywell International Inc. merged into Honeywell Inc., which as a result became a wholly-owned subsidiary of Honeywell International Inc. The merger has been accounted for as a pooling of interest. Based on our review of the operations and infrastructure of the combined companies, we expect that we will realize annual cost savings of at least $250 million in 2000, $575 million in S-6

2001 and $750 million in 2002. We expect to realize at least $750 million in cost savings in 2002 as follows: by achieving procurement and purchasing efficiencies by utilizing AlliedSignal's and Honeywell Inc.'s combined purchasing capabilities, centralizing the two companies' purchasing processes and benefiting from the added buying efficiencies that we expect as a result of higher volume purchases; by accelerating implementation of our 'Six Sigma' initiative to achieve defect-free performance in manufacturing and other business processes, and applying this initiative to Honeywell Inc.'s businesses, to further enhance the quality of our products and services and increase productivity; by rationalizing corporate overhead costs through the elimination of redundant corporate functions and facilities; by reducing overhead in our aerospace businesses by eliminating redundancies in the sales and administrative functions and field service operations of these businesses; by integrating our research and development programs and achieving research and development efficiencies; by reducing our infrastructure costs by integrating AlliedSignal's and Honeywell Inc.'s international operations and eliminating infrastructure redundancies; and by providing to Honeywell Inc.'s business units administrative services in the areas of accounting, human resources, travel, information technology and training, through AlliedSignal's centralized shared services organization, and eliminating similar services formerly provided by Honeywell Inc. to its business units. While we expect that we will be able to realize these cost savings, we can give no assurance that we will actually be able to do so. Our success in realizing these cost savings, and the timing of this realization, depends on the quality and speed of the integration of our two companies. We may not realize the cost savings that we anticipate from integrating our operations following completion of the merger as fully or as quickly as we expect for a number of reasons, including our large size and worldwide presence and the resulting complexity of our organization or unexpected events such as major changes in the markets in which we operate. See 'Cautionary Statement Concerning Forward-Looking Statements'. We continuously assess the relative strength of each business in our portfolio as to strategic fit, market position and profit contribution in order to upgrade its combined portfolio and identify operating units that will most benefit from increased investment. We identify acquisition candidates that will further our strategic plan and strengthen our existing core businesses. We also identify operating units that do not fit into our long-term strategic plan based on their market position, relative profitability or growth potential. These operating units are considered for potential divestiture, restructuring or other repositioning action subject to regulatory constraints. S-7

SEGMENT FINANCIAL DATA We evaluate segment performance based on segment profit, which excludes general corporate unallocated expenses, gains on sales of non-strategic businesses, equity income, other income (expense), interest and other financial charges, merger, repositioning and other charges, and other, which includes the gain on our disposition of our investment in AMP Incorporated common stock and litigation settlements. Intersegment sales approximate market and are not significant.

RECENT DEVELOPMENTS In February 2000, Honeywell completed its acquisition of Pittway Corporation, one of the world's leading manufacturers and distributors of security and fire systems and other low-voltage products for homes and buildings. Its systems and products are marketed globally under the Ademco, Notifier, System Sensor, ADI, Northern Computers and other popular brand names. Pittway had 1999 sales of $1.6 billion. Our acquisition of Pittway gives us access to the higher growth security and fire systems business. We expect that this will permit us to offer integrated solutions combining climate controls with security and fire systems. The value of the acquisition is approximately $2.2 billion, including the assumption of the net debt of Pittway of approximately $167 million. S-8

SUMMARY FINANCIAL INFORMATION We derived the summary financial information set out below for each of the years ended December 31, 1997 through 1999 from our audited consolidated financial statements for those years. This information is only a summary and you should read it together with our historical financial statements and related notes contained in the annual reports and other information that we have filed with the SEC and incorporated by reference. YEARS ENDED DECEMBER 31, --------------------------- 1999 1998 1997 ---- ---- ---- (IN MILLIONS) RESULTS OF OPERATIONS Net sales................................................... $23,735 $23,555 $22,499 Gross interest expense(1)................................... 287 300 298 Net income(2)............................................... 1,541 1,903 1,641 FINANCIAL POSITION AT YEAR-END Cash and cash equivalents................................... $ 1,991 $ 1,018 $ 745 Total debt(3)............................................... 5,066 4,966 3,632 Net debt(4)................................................. 3,075 3,948 2,887 Total shareowners' equity................................... 8,599 8,083 6,775 CASH FLOW DATA Net cash provided by operating activities................... $ 2,374 $ 1,974 $ 1,934 Net cash (used for) investing activities....................

(2) In 1999, includes merger, repositioning and other charges, and gains on the sales of our Laminate Systems business and our investment in AMP Incorporated common stock, resulting in a net after-tax charge of $624 million. In 1998, includes repositioning charges, a gain on settlement of litigation claims and a tax benefit resulting from the favorable resolution of certain prior-year research and development tax claims resulting in a net after-tax charge of $4 million. In 1997, includes repositioning and other charges, gains on the sales of our automotive Safety Restraints and certain Industrial Control businesses and a charge related to the 1996 sale of our automotive Braking Systems business resulting in a net after-tax charge of $5 million. (3) We define 'total debt' for this purpose as long-term debt, including current maturities, plus short-term borrowings and commercial paper. (4) We define 'net debt' for this purpose as total debt less cash and cash equivalents. (5) We define 'EBITDA' for this purpose as earnings before interest and other financial charges, taxes on income, depreciation, amortization and equity in income of affiliated companies without reduction for related other charges. EBITDA is a measure commonly used to analyze companies on the basis of operating performance. EBITDA is not a measure of financial S-9

performance under generally accepted accounting principles and should not be considered as an alternative to net income as a measure of performance, nor as an alternative to net cash provided by operating activities as a measure of liquidity. Because all companies do not calculate EBITDA in the same fashion, EBITDA as calculated by us may differ from EBITDA as calculated by other companies. (6) For the periods presented, we recorded certain charges and gains that have been excluded for the purpose of calculating 'adjusted EBITDA'. In 1999, excludes merger, repositioning and other charges, and gains on the sales of our Laminate Systems business and our investment in AMP Incorporated common stock, resulting in a net pre-tax charge of $913 million. In 1998, excludes repositioning charges, a gain on settlement of litigation claims and a tax benefit resulting, from the favorable resolution of certain prior-year research and development tax claims resulting in a net pre-tax charge of $30 million. In 1997, excludes repositioning and other charges, gains on the sales of our automotive Safety Restraints and certain Industrial Control businesses and a charge related to the 1996 sale of our automotive Braking Systems business, resulting in a net pre-tax charge of $38 million. (7) We define 'book capital' for this purpose as the sum of total debt, shareowners' equity, and net long-term deferred tax liabilities, which are long-term deferred income tax liabilities net of long-term deferred income tax assets. S-10

CAPITALIZATION The following table shows our capitalization (a) on a consolidated basis as of December 31, 1999, (b) pro forma for the acquisition of Pittway and the related issuance of commercial paper and the adjustment of cash balances to $750 million to eliminate excess cash balances carried for the Pittway acquisition and year 2000 contingency purposes, and (c) pro forma as adjusted for the issuance of the notes offered hereby and the repayment of existing indebtedness. Except as reflected herein, as of the date of this prospectus supplement there has been no material change to our capitalization since December 31, 1999.

DESCRIPTION OF THE NOTES The following description of the particular terms of the notes offered hereby supplements the description of the general terms and provisions of debt securities under the heading 'Description of Debt Securities' in the accompanying prospectus. Terms used in this prospectus supplement that are otherwise not defined will have the meanings given to them in the accompanying prospectus. GENERAL We will issue the notes in the aggregate principal amount of $1,000,000,000. The notes will mature at par on March 1, 2010. The notes will constitute part of the senior debt of Honeywell and will rank pari passu with all other unsecured and unsubordinated indebtedness of Honeywell. We will issue the notes only in book-entry form, in denominations of $1,000 and integral multiples of $1,000. Principal of and interest on the notes will be payable, and the transfer of notes will be registerable, through the Depositary as described below. The notes will bear interest at the annual rate shown on the cover of this prospectus supplement and will accrue interest from March 1, 2000 or from the most recent date to which interest has been paid or provided for. Interest will be payable twice a year, on March 1 and September 1, beginning September 1, 2000, to the person in whose name a note is registered at the close of business on the February 15 or August 15 that precedes the date on which interest will be paid. Interest payments for the notes will include accrued interest from and including March 1, 2000 or from and including the last date in respect of which interest has been paid, as the case may be, to, but excluding, the interest payment date or the date of maturity, as the case may be. Interest payable at the maturity of the notes will be payable to the registered holder of the note to whom principal is payable. Interest will be computed on the basis of a 360-day year of twelve 30-day months. If any interest payment date falls on a day that is not a business day, the interest payment will be postponed to the next day that is a business day, and no interest on such payment will accrue for the period from and after such interest payment date. If the maturity date of the notes falls on a day that is not a business day, the payment of interest and principal may be made on the next succeeding business day, and no interest on such payment will accrue for the period from and after the maturity date. As used in this prospectus supplement, 'business day' means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in the City of New York or in the place of presentation. The notes, the indenture and the underwriting agreement are governed by, and shall be construed in accordance with, the laws of the State of New York, United States of America, applicable to agreements made and to be performed wholly within such jurisdiction. In some circumstances, we may elect to discharge our obligations on the notes through defeasance or covenant defeasance. See 'Description of Debt Securities -- Defeasance Provisions' in the accompanying prospectus for more information about how we may do this. We may, without the consent of the holders of notes, issue additional notes having the same ranking and the same interest rate, maturity and other terms as the applicable notes. Any additional notes having such similar terms, together with the applicable notes, will constitute a single series of notes under the indenture. No additional notes may be issued if an event of default has occurred with respect to the applicable series of notes. We have appointed Chase Manhattan Bank Luxembourg S.A., as paying agent and transfer agent in Luxembourg with respect to the notes in definitive form. As long as the notes are listed on the Luxembourg Stock Exchange, we will maintain a paying and transfer agent in Luxembourg, and any change in the Luxembourg paying agent and transfer agent will be published in Luxembourg. See ' -- Notices' below. S-13

BOOK-ENTRY, DELIVERY AND FORM The notes will be issued in the form of one or more fully registered global notes (the 'Global Notes') which will be deposited with, or on behalf of, The Depository Trust Company, New York, New York (the 'Depositary' or 'DTC') and registered in the name of Cede & Co., the Depositary's nominee. Beneficial interests in the Global Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in the Depositary. Investors may elect to hold interests in the Global Notes through the Depositary, Clearstream Banking, Societe anonyme ('Clearstream, Luxembourg') or Morgan Guaranty Trust Company of New York, Brussels Office, as operator of the Euroclear System ('Euroclear') if they are participants of such systems, or indirectly through organizations which are participants in such systems. Clearstream, Luxembourg and Euroclear will hold interests on behalf of their participants through customers' securities accounts in Clearstream, Luxembourg's and Euroclear's names on the books of their respective depositaries, which in turn will hold such interests in customers' securities accounts in the depositaries' names on the books of the Depositary. Citibank, N.A. will act as depositary for Clearstream, Luxembourg and The Chase Manhattan Bank will act as depositary for Euroclear (in such capacities, the 'U.S. Depositaries'). Except as set forth below, the Global Notes may be transferred, in whole and not in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee. The Depositary has advised the Company as follows: the Depositary is a limited-purpose trust company organized under the New York Banking Law, a 'banking organization' within the meaning of the New York Banking Law, a member of the Federal Reserve System, a 'clearing corporation' within the meaning of the New York Uniform Commercial Code, and a 'clearing agency' registered pursuant to the provisions of Section 17A of the Exchange Act. The Depositary holds securities deposited with it by its participants and facilitates the settlement of transactions among its participants in such securities through electronic computerized book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. The Depositary's participants include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own the Depositary. Access to the Depositary book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. Clearstream, Luxembourg advises that it is incorporated under the laws of Luxembourg as a bank. Clearstream, Luxembourg holds securities for its customers ('Clearstream, Luxembourg Customers') and facilitates the clearance and settlement of securities transactions between Clearstream, Luxembourg Customers through electronic book-entry transfers between their accounts. Clearstream, Luxembourg provides to Clearstream, Luxembourg Customers, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream, Luxembourg interfaces with domestic securities markets in over 30 countries through established depository and custodial relationships. As a bank, Clearstream, Luxembourg is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream, Luxembourg Customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Clearstream, Luxembourg's U.S. customers are limited to securities brokers and dealers and banks. Indirect access to Clearstream, Luxembourg is also available to other institutions such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream, Luxembourg Customer. Distributions with respect to the notes held through Clearstream, Luxembourg will be credited to cash accounts of Clearstream, Luxembourg Customers in accordance with its rules and procedures, to the extent received by the U.S. Depositary for Clearstream, Luxembourg. Euroclear advises that it was created in 1968 to hold securities for its participants ('Euroclear Participants') and to clear and settle transactions between Euroclear Participants through S-14

simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by the Brussels, Belgium office of Morgan Guaranty Trust Company of New York (the 'Euroclear Operator'), under contract with Euroclear Clearance Systems, S.C., a Belgian cooperative corporation (the 'Cooperative'). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly. The Euroclear Operator is the Belgian branch of a New York banking corporation which is a member bank of the Federal Reserve System. As such, it is regulated and examined by the Board of Governors of the Federal Reserve System and the New York State Banking Department, as well as the Belgian Banking Commission. Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the 'Terms and Conditions'). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants and has no record of or relationship with persons holding through Euroclear Participants. Distributions with respect to the notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions, to the extent received by the U.S. Depositary for Euroclear. Euroclear further advises that investors that acquire, hold and transfer interests in the notes by book-entry through accounts with the Euroclear Operator or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the Global Notes. The Euroclear Operator advises that under Belgian law, investors that are credited with securities on the records of the Euroclear Operator have a co-property right in the fungible pool of interests in securities on deposit with the Euroclear Operator in an amount equal to the amount of interests in securities credited to their accounts. In the event of the insolvency of the Euroclear Operator, Euroclear Participants would have a right under Belgian law to the return of the amount and type of interests in securities credited to their accounts with the Euroclear Operator. If the Euroclear Operator did not have a sufficient amount of interests in securities on deposit of a particular type to cover the claims of all Participants credited with such interests in securities on the Euroclear Operator's records, all Participants having an amount of interests in securities of such type credited to their accounts with the Euroclear Operator would have the right under Belgian law to the return of their pro rata share of the amount of interests in securities actually on deposit. Under Belgian law, the Euroclear Operator is required to pass on the benefits of ownership in any interests in securities on deposit with it (such as dividends, voting rights and other entitlements) to any person credited with such interests in securities on its records. Individual certificates in respect of the notes will not be issued in exchange for the Global Notes, except in very limited circumstances. If DTC notifies us that it is unwilling or unable to S-15

continue as a clearing system in connection with the Global Notes or ceases to be a clearing agency registered under the Exchange Act, and a successor clearing system is not appointed by us within 90 days after receiving such notice from DTC or upon becoming aware that DTC is no longer so registered, we will issue or cause to be issued individual certificates in registered form on registration of transfer of, or in exchange for, book-entry interests in the notes represented by such Global Notes upon delivery of such Global Notes for cancellation. In the event that individual certificates are issued, holders of the notes will be able to receive payments (including principal and interest) on the notes and effect transfer of the notes at the offices of our paying and transfer agent in Luxembourg, Chase Manhattan Bank Luxembourg S.A. Title to book-entry interests in the notes will pass by book-entry registration of the transfer within the records of Clearstream, Luxembourg, Euroclear or DTC, as the case may be, in accordance with their respective procedures. Book-entry interests in the notes may be transferred within Clearstream, Luxembourg and within Euroclear and between Clearstream, Luxembourg and Euroclear in accordance with procedures established for these purposes by Clearstream, Luxembourg and Euroclear. Book-entry interests in the notes may be transferred within DTC in accordance with procedures established for this purpose by DTC. Transfers of book-entry interests in the notes among Clearstream, Luxembourg and Euroclear and DTC may be effected in accordance with procedures established for this purpose by Clearstream, Luxembourg, Euroclear and DTC. A further description of the Depositary's procedures with respect to the Global Notes is set forth in the prospectus under 'Book-Entry Issuance'. The Depositary has confirmed to us, the underwriters and the trustee that it intends to follow such procedures. GLOBAL CLEARANCE AND SETTLEMENT PROCEDURES Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with the Depositary's rules and will be settled in immediately available funds using the Depositary's Same-Day Funds Settlement System. Secondary market trading between Clearstream, Luxembourg Customers and/or Euroclear Participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream, Luxembourg and Euroclear and will be settled using the procedures applicable to conventional Eurobonds in immediately available funds. Cross-market transfers between persons holding directly or indirectly through the Depositary on the one hand, and directly or indirectly through Clearstream, Luxembourg Customers or Euroclear Participants, on the other, will be effected in the Depositary in accordance with the Depositary's rules on behalf of the relevant European international clearing system by its U.S. Depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. Depositary to take action to effect final settlement on its behalf by delivering interests in the notes to or receiving interests in the notes from the Depositary, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to the Depositary. Clearstream, Luxembourg Customers and Euroclear Participants may not deliver instructions directly to their respective U.S. Depositaries. Because of time-zone differences, credits of interests in the notes received in Clearstream, Luxembourg or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the Depositary settlement date. Such credits or any transactions involving interests in such notes settled during such processing will be reported to the relevant Clearstream, Luxembourg Customers or Euroclear Participants on such business day. Cash received in Clearstream, Luxembourg or Euroclear as a result of sales of interests in the notes by or through a Clearstream, Luxembourg Customer or a Euroclear Participant to a DTC participant will be received with value on the Depositary settlement S-16

date but will be available in the relevant Clearstream, Luxembourg or Euroclear cash account only as of the business day following settlement in the Depositary. Although the Depositary, Clearstream, Luxembourg and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of interests in the notes among participants of the Depositary, Clearstream, Luxembourg and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be changed or discontinued at any time. TAX REDEMPTION The notes may be redeemed as a whole, at our option at any time prior to maturity, upon the giving of a notice of redemption as described below, if we determine that, as a result of any change in or amendment to the laws (or any regulations or rulings promulgated thereunder) of the United States or of any political subdivision or taxing authority thereof or therein, or any change in official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment becomes effective on or after the date of this prospectus supplement, we have or will become obligated to pay additional amounts as described under ' -- Payment of Additional Amounts' below with respect to such notes for reasons outside our control and after taking reasonable measures to avoid such obligation. The notes will be redeemed at a redemption price equal to 100% of the principal amount thereof, together with accrued interest to the date fixed for redemption. Prior to the giving of any notice of redemption pursuant to this paragraph, we will deliver to the trustee: a certificate stating that we are entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to our right to so redeem have occurred, and an opinion of independent counsel satisfactory to the trustee to the effect that we have or will become obligated to pay such additional amounts for the reasons described above; provided that no such notice of redemption shall be given earlier than 60 days prior to the earliest date on which we would be obligated to pay such additional amounts if a payment in respect of the note were then due. Notice of redemption will be given not less than 30 nor more than 60 days prior to the date fixed for redemption, which date and the applicable redemption price will be specified in the notice. This notice will be given in accordance with ' -- Notices' below. PAYMENT OF ADDITIONAL AMOUNTS We will, subject to certain exceptions and limitations set forth below, pay such additional amounts to the beneficial owner of any note who is a United States alien as may be necessary in order that every net payment of principal of and interest on such note and any other amounts payable on such note, after withholding for or on account of any present or future tax, assessment or governmental charge imposed upon or as a result of such payment by the United States (or any political subdivision or taxing authority thereof or therein), will not be less than the amount provided for in such note to be then due and payable. We will not, however, be required to make any such payment of additional amounts to any beneficial owner for or on account of: any such tax, assessment or other governmental charge that would not have been so imposed but for the existence of any present or former connection between such beneficial owner (or between a fiduciary, settlor, beneficiary, member or shareholder of such beneficial owner, if such beneficial owner is an estate, a trust, a partnership or a corporation) and the United States and its possessions, including, without limitation, such beneficial owner (or such fiduciary, settlor, beneficiary, member or shareholder) being or having been a citizen or resident thereof or being or having been engaged in a trade or business or present therein or having, or having had, a permanent establishment therein; any estate, inheritance, gift, sales, transfer or personal property tax or any similar tax, assessment or governmental charge; S-17

any tax, assessment or other governmental charge imposed by reason of such beneficial owner's past or present status as a personal holding company or foreign personal holding company or controlled foreign corporation or passive foreign investment company with respect to the United States or as a corporation that accumulates earnings to avoid United States federal income tax; any tax, assessment or other governmental charge that is payable otherwise than by withholding from payments on or in respect of any note; any tax, assessment or other governmental charge that would not have been imposed but for the failure to comply with certification, information or other reporting requirements concerning the nationality, residence or identity of the beneficial owner of such note, if such compliance is required by statute or by regulation of the United States or of any political subdivision or taxing authority thereof or therein as a precondition to relief or exemption from such tax, assessment or other governmental charge; any tax, assessment or other governmental charge imposed by reason of such beneficial owner's past or present status as the actual or constructive owner of 10% or more of the total combined voting power of all classes of our stock entitled to vote or as a controlled foreign corporation that is related directly or indirectly to us through stock ownership; or any combination of these factors. Such additional amounts shall also not be paid with respect to any payment on a note to a United States alien who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of the United States (or any political subdivision thereof) to be included in the income, for tax purposes, of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such additional amounts had such beneficiary, settlor, member or beneficial owner, as the case may be, held its interest in the note directly. The term 'United States alien' means any person that is, for United States federal income tax purposes, a foreign corporation, a nonresident alien individual, a nonresident alien fiduciary of a foreign estate or trust, or a foreign partnership to the extent that one or more of its members is a foreign corporation, a nonresident alien individual or a nonresident alien fiduciary of a foreign estate or trust. NOTICES Notices to holders of the Notes will be sent by mail to the registered holders and will be published, whether the Notes are in global or definitive form, and so long as the Notes are listed on the Luxembourg Stock Exchange, in a daily newspaper of general circulation in Luxembourg. It is expected that publication will be made in Luxembourg in the Luxemburger Wort. Any such notice shall be deemed to have been given on the date of such publication or, if published more than once, on the date of the first such publication. So long as the notes are listed on the Luxembourg Stock Exchange, any appointment of or change in the Luxembourg paying agent and transfer agent will be published in Luxembourg in the manner set forth above. UNITED STATES FEDERAL TAXATION The following summary describes the material United States federal income and certain estate tax consequences of ownership and disposition of the notes. This summary provides general information only and is directed solely to original beneficial owners purchasing notes at the 'issue price,' that is, the first price at which a substantial amount of notes is sold to the public (excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers). This summary is based on the Internal Revenue Code of 1986, as amended to the date hereof (the 'Code'), existing administrative pronouncements and judicial decisions, existing and proposed Treasury Regulations currently in effect, and interpretations of the foregoing, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein, possibly S-18

with retroactive effect. This summary deals only with notes held as capital assets within the meaning of Section 1221 of the Code. This summary does not discuss all of the tax consequences that may be relevant to a beneficial owner in light of his particular circumstances or to beneficial owners subject to special rules, such as certain financial institutions, insurance companies, dealers in securities, persons holding notes in connection with a hedging transaction, 'straddle,' conversion transaction or other integrated transaction or persons who have ceased to be United States citizens or to be taxed as resident aliens. Persons considering the purchase of notes should consult their own tax advisors with regard to the application of the United States federal income and estate tax laws to their particular situations, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction. TAX CONSEQUENCES TO UNITED STATES PERSONS For purposes of the following discussion, a 'United States person' means a beneficial owner of a note that is, for United States federal income tax purposes: a citizen or resident of the United States, or a corporation or other entity treated as a corporation for United States federal income tax purposes created or organized in or under the laws of the United States, any State or the District of Columbia, or an estate or trust the income of which is subject to United States federal income taxation regardless of its source. Partnerships are subject to special tax rules and should contact their own tax advisors. PAYMENTS OF INTEREST Interest on a note will generally be taxable to a United States person as ordinary interest income at the time it is accrued or is received in accordance with the United States person's method of accounting for tax purposes. SALE, EXCHANGE OR RETIREMENT OF THE NOTES Upon the sale, exchange or retirement of a note, a United States person will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange or retirement and the United States person's adjusted tax basis in the note. For these purposes, the amount realized does not include any amount attributable to accrued interest on the note. Amounts attributable to accrued interest are treated as interest as described under ' -- Payments of Interest' above. A United States person's adjusted tax basis in a note generally will equal the cost of the note to the United States person. Gain or loss realized on the sale, exchange or redemption of a note will be capital gain or loss. Prospective investors should consult their own tax advisors regarding the treatment of capital gains (which may be taxed at lower rates than ordinary income for taxpayers who are individuals, trusts or estates) and losses (the deductibility of which is subject to limitations). BACKUP WITHHOLDING AND INFORMATION REPORTING Backup withholding and information reporting requirements may apply to certain payments of principal, premium and interest on a note, and to payments of proceeds of the sale or redemption of a note, to certain non-corporate United States persons. Honeywell, its agent, a broker, or any paying agent, as the case may be, will be required to withhold from any payment a tax equal to 31 percent of such payment if the United States person fails to furnish or certify its correct taxpayer identification number to the payor in the manner required, fails to certify, under penalty of perjury, that such United States person is not subject to backup withholding, or S-19

otherwise fails to comply with the applicable requirements of the backup withholding rules. Any amounts withheld under the backup withholding rules from a payment to a United States person may be credited against such United States person's United States federal income tax and may entitle such United States person to a refund, provided that the required information is furnished to the Internal Revenue Service. TAX CONSEQUENCES TO NON-UNITED STATES PERSONS As used herein, the term 'non-United States person' means a beneficial owner of a note that is, for United States federal income tax purposes: a nonresident alien individual, or a foreign corporation, or an estate or trust that is not taxable in the United States on its world-wide income. INCOME AND WITHHOLDING TAX FOR NON-UNITED STATES PERSONS The discussion under this heading is subject to the discussion of backup withholding below. Payments of principal and interest on a note that is beneficially owned by a non-United States person will not be subject to United States federal withholding tax; provided, that in the case of interest: (a) each of the following conditions is met: the beneficial owner does not actually or constructively own 10% or more of the total combined voting power of all classes of Honeywell stock entitled to vote, and the beneficial owner is not a controlled foreign corporation that is related, directly or indirectly, to us through stock ownership, and either -- the beneficial owner of the note provides an IRS Form W-8 or W-8 BEN certifying to the person otherwise required to withhold United States federal income tax from such interest that it is not a United States person and provides its name and address, or -- a securities clearing organization, bank or other financial institution that holds customers' securities in the ordinary course of its trade or business (a 'financial institution') and holds an interest in the note certifies to the person otherwise required to withhold United States federal income tax from such interest that such statement has been received from the beneficial owner by it or by a financial institution between it and the beneficial owner and furnishes the payor with a copy thereof; or (b) the beneficial owner is entitled to the benefits of an income tax treaty under which the interest is exempt from United States federal withholding tax and the beneficial owner of the note or such owner's agent provides an IRS Form 1001 or W-8 BEN claiming the exemption; or (c) the beneficial owner conducts a trade or business in the United States to which the interest is effectively connected and the beneficial owner of the note or such owner's agent provides an IRS Form 4224 or W-8 ECI; provided that in each such case, the relevant certification or IRS Form is delivered pursuant to applicable procedures and is properly transmitted to the person otherwise required to withhold United States federal income tax, and none of the persons receiving the relevant certification or IRS Form has actual knowledge that the certification or any statement on the IRS Form is false. Some of these procedures will change after December 31, 2000. A non-United States person will not be subject to United States federal withholding tax on any gain realized on the sale, exchange or other disposition of a note unless the gain is S-20

effectively connected with the beneficial owner's trade or business in the United States or, in the case of an individual, the beneficial owner is present in the United States for 183 days or more in the taxable year in which the sale, exchange or other disposition occurs and certain other conditions are met. A note owned by an individual who at the time of death is not, for United States estate tax purposes, a citizen or resident of the United States generally will not be subject to United States federal estate tax as a result of such individual's death if the individual does not actually or constructively own 10% or more of the total combined voting power or all classes of Honeywell stock entitled to vote and, at the time of such individual's death the income on the note would not have been effectively connected with a United States trade or business of the individual. If a non-United States person owning a note is engaged in a trade or business in the United States, and if interest on the note (or gain realized on its sale, exchange or other disposition) is effectively connected with the conduct of such trade or business, such owner, although exempt from the withholding tax discussed in the preceding paragraphs, will generally be subject to regular United States income tax on such effectively connected income in the same manner as if it were a United States person. In addition, if such owner is a foreign corporation, it may be subject to a 30% branch profits tax (unless reduced or eliminated by an applicable treaty) of its effectively connected earnings and profits for the taxable year, subject to certain adjustments. For purposes of the branch profits tax, interest on, and any gain recognized on the sale, exchange or other disposition of, a note will be included in the effectively connected earnings and profits of such owner if such interest or gain, as the case may be, is effectively connected with the conduct by such owner of a trade or business in the United States. Each owner of a note should be aware that if it does not properly provide the required IRS form, or if the IRS form (or, if permissible, a copy of such form) is not properly transmitted to and received by the United States person otherwise required to withhold United States federal income tax, interest on the note may be subject to United States withholding tax at a 30% rate, and the owner will not be entitled to any additional amounts from us described under the heading 'Description of Notes -- Payment of Additional Amounts' with respect to such tax. Such tax, however, may in certain circumstances be allowed as a refund or as a credit against such owner's United States federal income tax. The foregoing does not deal with all aspects of federal income tax withholding that may be relevant to a non-United States person that owns a note. Investors are advised to consult their own tax advisors for specific advice concerning the ownership and disposition of notes. BACKUP WITHHOLDING AND INFORMATION REPORTING Under current Treasury Regulations, backup withholding (imposed at the rate of 31 percent) will not apply to payments made by us or a paying agent to an owner in respect of a note if the certifications described above are received, provided in each case that we or the paying agent, as the case may be, do not have actual knowledge that the payee is a United States person. Under current Treasury Regulations, payments of the proceeds from the sale, exchange or other disposition of a note made to or through a foreign office of a broker (including a custodian, nominee or other agent acting on behalf of the beneficial owner of a note) generally will not be subject to information reporting or backup withholding. However, if such broker is a United States person, a controlled foreign corporation for United States federal income tax purposes or a foreign person with certain connections with the United States, then information reporting will be required unless the broker has in its records documentary evidence that the beneficial owner is not a United States person and certain other conditions are met or the beneficial owner otherwise establishes an exemption. Backup withholding may apply to any payment that such broker is required to report if such broker has actual knowledge that the payee is a United States person. Payments to or through the United States office of a broker are subject to information reporting and backup withholding unless the beneficial owner certifies, under penalties of perjury, that it is a non-United States person and that it satisfies certain other conditions or otherwise establishes an exemption from information reporting and backup withholding. S-21

New Treasury Regulations, which generally apply to payments made after December 31, 2000, modify the foregoing rules in certain respects. Non-United States persons owning notes should consult their own tax advisors regarding the application of information reporting and backup withholding in their particular situations, the availability of an exemption therefrom, and the procedure for obtaining such an exemption, both under current Treasury Regulations and the new Treasury Regulations. Backup withholding is not a separate tax, but is allowed as a refund or credit against the owner's United States federal income tax, provided the necessary information is furnished to the Internal Revenue Service. Interest on a note that is beneficially owned by a non-United States person will be reported annually on IRS Form 1042-S, which must be filed with the Internal Revenue Service and furnished to such beneficial owner. The United States federal income tax discussion set forth above is included for general information only and may not be applicable depending upon an owner's particular situation. Owners should consult their own tax advisors with respect to the tax consequences to them of the ownership and disposition of the notes, including the tax consequences under state, local, foreign and other tax laws and the possible effects of changes in federal or other tax laws.

UNDERWRITING Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has severally agreed to purchase, and we have agreed to sell to each underwriter, the principal amount of notes stated opposite the name of each underwriter. PRINCIPAL AMOUNT UNDERWRITER OF NOTES - ----------- -------------- Salomon Smith Barney Inc. ......................... $ 410,000,000 J.P. Morgan Securities Inc. ....................... 410,000,000 Banc of America Securities LLC..................... 45,000,000 Barclays Bank PLC.................................. 45,000,000 Chase Securities Inc. ............................. 45,000,000 Deutsche Bank Securities Inc....................... 45,000,000 -------------- Total.......................................... $1,000,000,000 -------------- -------------- Salomon Smith Barney Inc. and J.P. Morgan Securities Inc. are joint book-running managers for our offering of notes. The underwriting agreement provides that the obligations of the several underwriters to purchase the notes included in this offering are subject to approval of certain legal matters by counsel and to certain other conditions. The underwriters are obligated to purchase all the notes if they purchase any of the notes. The underwriters propose to offer some of the notes directly to the public at the public offering price stated on the cover page of this prospectus supplement and some of the notes to certain dealers at the public offering price less a concession not in excess of .30% of the aggregate principal amount of the notes. The underwriters may allow, and these dealers may reallow, a concession not in excess of .25% of the aggregate principal amount of the notes on sales to certain other dealers. After the initial offering of the notes to the public, the public offering price and these concessions may be changed by the underwriters. In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include over-allotment, syndicate covering transactions and stabilizing transactions. Over-allotment involves syndicate sales of notes in excess of the principal amount of notes to be purchased by the underwriters in the offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of notes made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress. The underwriters may also impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when they, in covering syndicate short positions or making stabilizing purchases, repurchase notes originally sold by that syndicate member. Any of these activities may cause the price of the notes to be higher than the price that otherwise would exist in the open market in the absence of such transactions. These transactions may be effected in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time. We estimate that the total expenses of this offering will be approximately $750,000. The underwriters and their affiliates have performed certain investment banking and advisory and general financing and banking services for us from time to time for which they have received customary fees and expenses. The underwriters and their affiliates may, from time to time, be customers of, engage in transactions with and perform services for us in the ordinary course of their business. Lawrence A. Bossidy, Chairman of the Board and a director of Honeywell, is also a director of J.P. Morgan & Co. Incorporated. J.P. Morgan Securities Inc. is a subsidiary of J.P. Morgan & Co. Incorporated. S-23

Hans W. Becherer, Andrew C. Sigler and John R. Stafford, directors of Honeywell, are also directors of The Chase Manhattan Corporation and The Chase Manhattan Bank, which are affiliates of Chase Securities Inc. The Chase Manhattan Bank is the trustee under the indenture. Chase Manhattan Bank Luxembourg S.A. is the Luxembourg paying agent and transfer agent for the notes. We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make in respect of any of those liabilities. The notes are offered for sale in those jurisdictions in the United States, Europe, Asia and elsewhere where it is lawful to make such offers. Each of the underwriters has represented and agreed that it has not and will not offer, sell or deliver any of the notes directly or indirectly, or distribute this prospectus supplement or the prospectus or any other offering material relating to the notes, in or from any jurisdiction except under circumstances that will result in compliance with the applicable laws and regulations thereof and that will not impose any obligations on us except as set forth in the underwriting agreement.

We have been advised by the underwriters for the notes that they intend to make a market in the notes, but they are not obligated to do so and may discontinue such market-making at any time without notice.

On June 7, 1999, AlliedSignal and Honeywell announced that they had entered into a merger agreement providing for the combination of the two companies. Under this agreement, AlliedSignal will be renamed Honeywell International Inc. at the effective time of the combination. When the combination is completed, Honeywell shareowners will be entitled to receive 1.875 shares of Honeywell International common stock for each share of Honeywell common stock plus cash in lieu of any fractional shares. Blossom Acquisition Corp., a wholly owned subsidiary of AlliedSignal, will merge with and into Honeywell at the effective time of the combination, and Honeywell will become a wholly owned subsidiary of Honeywell International. The headquarters of Honeywell International will remain in Morris Township, New Jersey at the current location of AlliedSignal's headquarters. The combination with Honeywell is subject to approval by both AlliedSignal and Honeywell shareowners and by European Commission and U.S. antitrust regulators, as well as to other customary conditions. We expect that the combination will be completed during the fall of 1999. Founded in 1885, Honeywell is one of the leading technology and controls companies in the world, serving customers in homes, commercial buildings, the industrial arena and space and aviation. Honeywell's home and building control business is a global provider of comfortable, healthy, safe and energy-efficient indoor environments, offering more than 3,500 products to both the consumer market and the building industry. The industrial control business of Honeywell is a worldwide leader in automation solutions from sensors to integrated systems, serving industries such as hydrocarbon processing, chemicals and pulp and paper. Honeywell's space and aviation control business is a leading supplier of avionics systems and products for the commercial, 4

military and space markets with customers ranging from aircraft manufacturers and business aircraft operators to prime space contractors and the U.S. government. For more information about the proposed combination with Honeywell, we refer you to our joint proxy statement/prospectus dated July 23, 1999 that we filed with the SEC (Registration No. 333-82049), a copy of which is available to you upon request. See 'Where You Can Find More Information About AlliedSignal'. We will provide updated information about the combination with Honeywell in the prospectus supplement relating to a series of debt securities. RATIO OF EARNINGS TO FIXED CHARGES AND PREFERRED STOCK DIVIDENDS The following table sets forth the historical ratios of earnings to fixed charges and preferred stock dividends of AlliedSignal for the periods indicated: SIX MONTHS ENDED JUNE 30, YEARS ENDED DECEMBER 31, - -------------------- ------------------------------------------------------------- 1999 1998 1998 1997 1996 1995 1994 - ---- ---- ---- ---- ---- ---- ---- 11.25 10.75 9.41 8.20 7.28 6.25 6.21 The ratio of earnings to fixed charges is generally computed by dividing the sum of net income, income taxes and fixed charges (net of capitalized interest) less undistributed equity income by fixed charges. Fixed charges represent gross interest and amortization of debt discount and expense and the interest factor of all rentals, consisting of an appropriate interest factor on operating leases. USE OF PROCEEDS Unless otherwise specified in the applicable prospectus supplement, the net proceeds we receive from the sale of the securities offered by this prospectus and the accompanying prospectus supplement will be used for general corporate purposes. General corporate purposes may include the repayment of debt, investments in or extensions of credit to our subsidiaries, or the financing of possible acquisitions or business expansion. The net proceeds may be invested temporarily or applied to repay short-term debt until they are used for their stated purpose. DESCRIPTION OF DEBT SECURITIES The following description of the terms of the debt securities sets forth certain general terms that may apply to the debt securities. The particular terms of any debt securities will be described in the related prospectus supplement. GENERAL Debt securities will be our unsecured, unsubordinated debt securities. They will be issued under an indenture dated as of October 1, 1985, as amended by a first supplemental indenture dated as of February 1, 1991 and a second supplemental indenture dated as of November 1, 1997, between us and The Chase Manhattan Bank, as trustee. The following summary of certain provisions of the indenture is not complete. You should refer to the indenture (including the amendments to it) which are exhibits to the registration statement of which this prospectus is a part (Registration No. 333-86157). The indenture has been qualified under the Trust Indenture Act. Section references below are to the section in the indenture. The referenced sections of the indenture and the definitions of capitalized terms in the indenture are incorporated by reference in this prospectus. The indenture does not limit the amount of debt that we may issue. The indenture provides that debt securities may be issued thereunder up to the principal amount authorized by us from time to time. We have issued $1,609,760,000 principal amount of debt securities under our existing indenture with The Chase Manhattan Bank as of the date of this prospectus. 5

The debt securities may be issued in one or more separate series. The prospectus supplement relating to the particular series of debt securities being offered will specify the particular amounts, prices and terms of those debt securities. These terms may include: the title and type of the debt securities; any limit on the aggregate principal amount or aggregate initial offering price of the debt securities and the amount payable upon acceleration; the purchase price of the debt securities; the dates on which the principal of the debt securities will be payable; the interest rates (including the interest rates, if any, applicable to overdue payments) of the debt securities, or the method for determining those rates, and the interest payment dates for the debt securities; the places where payments may be made on the debt securities; any mandatory or optional redemption provisions applicable to the debt securities; any sinking fund or analogous provisions applicable to the debt securities; the authorized denominations of the debt securities, if other than $1,000 and integral multiples of $1,000; if other than U.S. dollars, the currency, currencies or composite currencies, in which purchase price and/or payments on the debt securities will be payable (which currencies may be different for principal, premium and interest payments); any conversion or exchange provisions applicable to the debt securities; any additional events of default applicable to the debt securities not set forth in the indenture; and any other specific terms of the debt securities. Some of the debt securities may be issued as original issue discount debt securities. Original issue discount debt securities bear no interest or bear interest at below-market rates and will be sold at a discount below their stated principal amount. The prospectus supplement will also contain any special tax, accounting or other information relating to original issue discount debt securities or relating to certain other kinds of debt securities that may be offered, including debt securities linked to an index or payable in currencies other than U.S. dollars. The debt securities will be issued only in fully registered form without coupons. The indenture also provides that debt securities of a series may be issued as permanent global debt securities. See ' -- Permanent Global Debt Securities' and 'Book-Entry Issuance' below. No service charge will be made for any transfer or exchange of debt securities, but we may require payment of any taxes or other governmental charges. Principal of and any premium and interest on the debt securities will be payable at the corporate trust office of the trustee in New York City. Transfers or exchanges of debt securities may be made at the same location. Payment of interest on any debt securities may be made at our option by check mailed to the registered holders of the debt securities at their registered addresses. In connection with any payment on a debt security, we may require the holder to certify information to us. In the absence of such certification, we may rely on any legal presumption to determine whether we must deduct or withhold taxes, assessments or governmental charges from a payment. We may at any time repurchase debt securities at any price on the open market or otherwise. We may in our discretion hold, resell or surrender to the trustee for cancellation any debt securities that we acquire. 6

COVENANTS The indenture does not limit our ability to enter into highly leveraged transactions, nor does it provide special protection to holders of debt securities in the event of such transactions. The indenture does not provide special protection in the event of a sudden and dramatic decline in our credit quality resulting from a takeover, recapitalization or similar restructuring. In addition, the indenture does not limit the amount of indebtedness incurred by our subsidiaries. The covenants contained in the indenture are set forth below. Limitation on Liens. In the indenture, we covenant not to issue, assume or guarantee any indebtedness for borrowed money secured by liens on any property located in the United States which is -- in the opinion of our board of directors, a principal manufacturing property, or -- an oil, gas or mineral producing property, or any shares of capital stock or indebtedness of any subsidiary owning such property, without equally and ratably securing the debt securities, subject to certain exceptions specified in the indenture. These exceptions include: existing liens on our property or liens on property of corporations at the time such corporations become subsidiaries of or are merged with us; liens existing on property when acquired, or incurred to finance the purchase price thereof; certain liens on property to secure the cost of exploration, drilling or development of, or improvements on, such property; certain liens in favor of or required by contracts with governmental entities; and indebtedness secured by liens otherwise prohibited by such covenant not exceeding 10% of the consolidated net tangible assets of AlliedSignal and our consolidated subsidiaries (Sections 101 and 1005). Transfers of oil, gas or other minerals in place for a period of time until the transferee receives a specified amount of money or of such minerals or any other transfers commonly referred to as 'production payments,' are outside the scope of this covenant and are permitted without restriction. Limitation on Sale and Lease-Back Transactions. We also covenant not to enter into any sale and lease-back transaction covering any property located in the United States which is in the opinion of our board of directors, a principal manufacturing property, or an oil, gas or mineral producing property, unless: we would be entitled under the provisions described under ' -- Limitation on Liens' to incur debt equal to the value of such sale and lease-back transaction, secured by liens on the property to be leased, without equally securing the outstanding debt securities; or we, during the four months following the effective date of such sale and lease-back transaction, apply an amount equal to the value of such sale and lease-back transaction to the voluntary retirement of long-term indebtedness of AlliedSignal or our subsidiaries (Sections 101 and 1006). CONSOLIDATION, MERGER AND SALE OF ASSETS We may, without the consent of the holders of any debt securities, consolidate or merge with any other person or transfer or lease all or substantially all of our assets to another person or permit another corporation to merge into AlliedSignal, provided that: the successor is a person organized under U.S. law; 7

the successor person, if not AlliedSignal, assumes our obligations on the debt securities and under the indenture; after giving effect to the transaction, no event of default, and no event which, after notice or lapse of time or both, would become an event of default, shall have occurred and be continuing; and certain other conditions are met (Section 801A). DEFEASANCE PROVISIONS The indenture contains a provision that, if made applicable to any series of debt securities, permits us to elect: (1) to defease and be discharged from all of our obligations (except for certain obligations to register the transfer or exchange of debt securities, to replace stolen, lost or mutilated debt securities, to maintain paying agencies and to hold moneys for payment in trust) with respect to any series of debt securities denominated and payable in U.S. dollars then outstanding ('defeasance'); and/or (2) to be released from our obligations under the covenants set forth in Sections 1005 (limitation on liens) and 1006 (limitation on sale and lease-back transactions) and from the consequences of an event of default resulting from a breach of those covenants or a cross-default ('covenant defeasance') (Sections 403 and 1008). To elect defeasance or covenant defeasance, we must deposit in trust with the trustee money and/or U.S. government obligations (which are direct obligations of the United States backed by its full faith and credit) which through the payment of principal and interest in accordance with their terms will provide sufficient money, without reinvestment, to repay in full those debt securities, including any sinking fund obligations (Section 101). As a condition to defeasance or covenant defeasance, we must deliver to the trustee an opinion of counsel that the holders of the debt securities will not recognize income, gain or loss for Federal income tax purposes as a result of the defeasance or covenant defeasance. In the case of defeasance under clause (1) above, that opinion must refer to and be based upon a ruling received by us from the Internal Revenue Service or published as a revenue ruling or upon a change in applicable Federal income tax law, and such defeasance may not result in any series of debt securities, if it is listed for trading on the New York Stock Exchange, being delisted. Under Federal income tax law as of the date of this prospectus, defeasance would likely be treated as a taxable exchange of debt securities for interests in the defeasance trust. As a result, a holder would recognize gain or loss equal to the difference between the holder's cost or other tax basis for the debt securities and the value of the holder's proportionate interest in the defeasance trust. That holder would thereafter be required to include in income a proportionate share of the income, gain or loss, as the case may be, of the defeasance trust. Under Federal income tax law as of the date of this prospectus, covenant defeasance would ordinarily not be treated as a taxable exchange of debt securities. Purchasers of debt securities should consult their own advisors as to the tax consequences to them of defeasance and covenant defeasance, including the applicability and effect of tax laws other than the Federal income tax law. If we exercise our covenant defeasance option with respect to a particular series of debt securities, then even if there were a default under the related covenant, payment of those debt securities could not be accelerated. We may exercise our defeasance option with respect to a particular series of debt securities even if we previously had exercised our covenant defeasance option. If we exercise our defeasance option, payment of those debt securities may not be accelerated because of any event of default. If we exercise our defeasance option or covenant defeasance option and an acceleration were to occur, the realizable value at the acceleration date of the money and U.S. government obligations in the defeasance trust could be less than the principal and interest then due on those debt securities. This is because the required deposit of money and/or U.S. government obligations in the defeasance trust is based upon scheduled cash flows rather than market value, which will vary depending upon interest rates and other factors. 8

MODIFICATION We and the trustee may make modifications and amendments to the indenture with the consent of the holders of not less than a majority in principal amount of each series of outstanding debt securities affected by the modification or amendment. Without the consent of each affected holder, no modification may: change the stated maturity of any debt securities; reduce the principal amount of any debt securities; reduce the rate or extend the time of payment of interest or any premium of any debt securities; impair the right to institute suit for the enforcement of any payment on or after its due date; or reduce the percentage of the principal amount of debt securities required to approve any supplemental indenture or any waiver under the indenture (Section 902). We and the trustee may amend the indenture without the consent of the holders of debt securities: to reflect our merger with another person; to replace the trustee; to issue a new series of debt securities; to effect modifications that do not adversely affect any outstanding series of debt securities; and for certain other purposes (Section 901). Any modification of the indenture subordinating any series of debt securities issued under it to any other indebtedness of AlliedSignal will not be effective without each holder's consent. EVENTS OF DEFAULT; WAIVER An event of default with respect to any series of debt securities will occur under the indenture if: we fail to pay principal of or any premium on the series, except for principal due upon sinking fund redemptions; we fail to pay any installment of interest on the series for a period of 30 days; we fail to pay any sinking fund redemption on the series for a period of 30 days; we fail to perform any other covenant in the indenture for 90 days after notice; we or a court take certain actions relating to the bankruptcy, insolvency or reorganization of AlliedSignal for the benefit of our creditors; or any other event of default specified with respect to debt securities of that series as described in the applicable prospectus supplement occurs (Section 501). No event of default with respect to a particular series of debt securities issued under the indenture necessarily constitutes an event of default with respect to any other series of debt securities (Section 501). On the occurrence of an event of default with respect to a series of debt securities, the trustee or the holders of at least 25% in principal amount at maturity of such series of debt securities then outstanding may declare the principal, or in the case of debt securities sold at an original issue discount, the amount specified in the terms thereof, to be due and payable immediately (Section 501). Subject to certain conditions, the declaration described in the preceding paragraph may be annulled and past defaults, except uncured payment defaults and certain other specified defaults, may be waived by the holders of not less than a majority in aggregate principal amount at 9

maturity of outstanding debt securities of the series affected by any event of default (Sections 501, 502 and 507). Upon payment of the principal amount in respect of an event of default on any series of debt securities, together with any premium or interest due thereon, all of our obligations in respect to payment of indebtedness on such debt securities will terminate (Section 401). The indenture requires the trustee to, within 90 days after the occurrence of a default with respect to any outstanding series of debt securities, give the holders of that series notice of the default if uncured. The trustee may withhold this notice of default, except for default in the payment of principal of or any premium or interest on, or of any sinking fund payment with respect to, such series of debt securities, if it considers such withholding to be in the interest of holders of debt securities (Section 508). We are required annually to file with the trustee a certificate stating that no default exists under the indenture, or specifying the nature and status of any default (Section 1004). Subject to provisions relating to its duties in case of default, the trustee is under no obligation to exercise any of its rights or powers under the indenture at the request, order or direction of any holders of debt securities unless such holders of debt securities shall have offered to the trustee reasonable security or indemnity (Section 603). Subject to that provision for security or indemnification, the holders of a majority in principal amount of the debt securities of any series then outstanding will have the right to direct the time, method and place of conducting any proceeding for any remedy available to, or exercising any trust or power conferred on, the trustee with respect to the debt securities of that series (Section 504). INFORMATION CONCERNING THE TRUSTEE UNDER THE INDENTURE We and some of our subsidiaries and affiliates maintain deposits with, and conduct other banking transactions with, The Chase Manhattan Bank in the ordinary course of business. These include: The Chase Manhattan Bank is the trustee under the indenture under which our Serial Zero Coupon Bonds Due through 2009 are outstanding. The Chase Manhattan Bank is fiscal agent for our 8% Bonds Due May 15, 2006. The Chase Manhattan Bank is a lender under one of our revolving credit agreements with a group of banks. The Chase Manhattan Bank has a commitment of $50 million under this revolving credit agreement. PERMANENT GLOBAL DEBT SECURITIES The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with a depositary or its nominee identified in the related prospectus supplement (Section 203). Unless otherwise indicated in the related prospectus supplement, any such depositary will be DTC. Unless otherwise provided in the related prospectus supplement, a global security may not be transferred except as a whole to the depositary, a nominee of the depositary or their successors unless it is exchanged in whole or in part for debt securities in individually certificated form. For a description of the depositary arrangements, see 'Book-Entry Issuance'. Any additional terms of the depositary arrangement with respect to any series of debt securities and the rights of and limitations on owners of beneficial interests in a global security representing a series of debt securities may be described in the related prospectus supplement. BOOK-ENTRY ISSUANCE Most series of debt securities will be book-entry securities. Upon issuance, all book-entry securities of the same issue will be represented by one or more fully registered global securities, without interest coupons. Each global security will be deposited with, or on behalf of, The Depository Trust Company or 'DTC', a securities depository, and will be registered in the name of 10

DTC or a nominee of DTC. DTC will thus be the only registered holder of these debt securities and will be considered the sole owner of the securities for purposes of the indenture. Purchasers may only hold interests in the global securities through DTC if they are a participant in the DTC system. Purchasers may also hold interests through a securities intermediary -- banks, brokerage houses and other institutions that maintain securities accounts for customers -- that has an account with DTC or its nominee. DTC will maintain accounts showing the securities holdings of its participants, and these participants will in turn maintain accounts showing the securities holdings of their customers. Some of these customers may themselves be securities intermediaries holding debt securities for their customers. Thus, each beneficial owner of a book-entry security will hold that security indirectly through a hierarchy of intermediaries, with DTC at the 'top' and the beneficial owner's own securities intermediary at the 'bottom.' The securities of each beneficial owner of a book-entry security will be evidenced solely by entries on the books of the beneficial owner's securities intermediary. The actual purchaser of the securities will generally not be entitled to have the securities represented by the global securities registered in its name and will not be considered the owner under the indenture. In most cases, a beneficial owner will also not be able to obtain a paper certificate evidencing the holder's ownership of securities. The book-entry system for holding securities eliminates the need for physical movement of certificates. The laws of some jurisdictions require some purchasers of securities to take physical delivery of their securities in definitive form. These laws may impair the ability to transfer book-entry securities. Unless otherwise specified in the prospectus supplement with respect to a series of debt securities, a beneficial owner of book-entry securities represented by a global security may exchange the securities for definitive or paper securities only if: DTC is unwilling or unable to continue as depositary for such global security and AlliedSignal is unable to find a qualified replacement for DTC within 90 days; at any time DTC ceases to be a clearing agency registered under the Securities Exchange Act of 1934; or AlliedSignal in its sole discretion decides to allow some or all book-entry securities to be exchangeable for definitive securities in registered form. Any global security that is exchangeable will be exchangeable in whole for definitive securities in registered form, with the same terms and of an equal aggregate principal amount, in denominations of $1,000 and whole multiples of $1,000. Definitive notes will be registered in the name or names of the person or persons specified by DTC in a written instruction to the registrar of the securities. DTC may base its written instruction upon directions it receives from its participants. In this prospectus and the accompanying prospectus supplement, for book-entry securities, references to actions taken by security holders will mean actions taken by DTC upon instructions from its participants, and references to payments and notices of redemption to security holders will mean payments and notices of redemption to DTC as the registered holder of the securities for distribution to participants in accordance with DTC's procedures. DTC is a limited purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a 'clearing corporation' within the meaning of the New York Uniform Commercial Code and a 'clearing agency' registered under section 17A of the Securities Exchange Act of 1934. The rules applicable to DTC and its participants are on file with the SEC. DTC's management is aware that some computer applications, systems, and the like for processing data that are dependent upon calendar dates, including dates before, on, and after January 1, 2000, may encounter 'Year 2000 problems.' DTC has informed its participants and other members of the financial community that it has developed and is implementing a program so that its systems, as they relate to the timely payment of distributions to securityholders, book-entry deliveries, and settlement of trades within DTC, continue to function appropriately. This 11

program includes a technical assessment and a remediation plan, each of which is complete. Additionally, DTC's plan includes a testing phase, which is expected to be completed within appropriate time frames. AlliedSignal will not have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the book-entry securities or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests. PLAN OF DISTRIBUTION We may sell the debt securities: through underwriters, through agents, or directly to a limited number of institutional purchasers or to a single purchaser. The prospectus supplement will set forth the terms of the offering of the debt securities, including the following: the name or names of any underwriters; the purchase price and the proceeds we will receive from the sale; any underwriting discounts and other items constituting underwriters' compensation; any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers; and any securities exchanges on which the debt securities of the series may be listed. If underwriters are used in the sale, the debt securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The debt securities may be either offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. The obligations of the underwriters to purchase debt securities will be subject to conditions precedent and the underwriters will be obligated to purchase all the debt securities of a series if any are purchased. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. Debt securities may be sold directly by us or through agents designated by us from time to time. Any agent involved in the offer or sale of the debt securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to that agent will be set forth, in the prospectus supplement. Unless otherwise indicated in the prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment. We may authorize agents or underwriters to solicit offers by certain types of institutions to purchase debt securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts. These contracts will provide for payment and delivery on a specified date in the future. The conditions to these contracts and the commissions payable for solicitation of such contracts will be set forth in the applicable prospectus supplement. Agents and underwriters may be entitled to indemnification by us against civil liabilities arising out of this prospectus, including liabilities under the Securities Act of 1933, or to contribution with respect to payments which the agents or underwriters may be required to make relating to those liabilities. Each series of debt securities will be a new issue of securities with no established trading market. Any underwriter may make a market in the debt securities, but will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of the trading market for any debt securities. 12

Agents and underwriters may be engaged in transactions with, or perform commercial or investment banking or other services for, us or our subsidiaries or affiliates, in the ordinary course of business. We estimate that our expenses associated with this offering will be approximately $0.8 million, excluding underwriting discounts and commissions. EXPERTS The audited financial statements incorporated in this prospectus by reference to our Annual Report on Form 10-K for the year ended December 31, 1998 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, independent accountants, given on the authority of that firm as experts in auditing and accounting. With respect to the unaudited consolidated financial information of AlliedSignal for the three-month periods ended March 31, 1999 and 1998 and the three-month and six-month periods ended June 30, 1999 and 1998 incorporated by reference in this prospectus, PricewaterhouseCoopers LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports dated May 13, 1999 and August 11, 1999 incorporated by reference in this prospectus, state that they did not audit and did not express an opinion on that unaudited consolidated financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. PricewaterhouseCoopers LLP is not subject to the liability provisions of Section 11 of the Securities Act for their report on the unaudited consolidated financial information because that report is not a 'report' or a 'part' of the registration statement prepared or certified by PricewaterhouseCoopers LLP within the meaning of Sections 7 and 11 of the Securities Act. LEGAL OPINIONS Certain legal matters will be passed upon for AlliedSignal by J. Edward Smith, Assistant General Counsel, Corporate and Finance, of AlliedSignal, and for any underwriters by Cravath, Swaine & Moore, New York, New York. Mr. Smith beneficially owns shares of AlliedSignal common stock and has options to acquire additional shares of AlliedSignal common stock granted under option plans of AlliedSignal. In the opinions described above, certain assumptions will be made regarding future action required to be taken by AlliedSignal and others in connection with the issuance and sale of any particular offered debt securities, the specific terms of those offered debt securities and other matters which may affect the validity of those offered debt securities but which cannot be ascertained on the date of the relevant opinion. 13
