UNITED TECHNOLOGIES CORPORATION, a Delaware corporation (herein called the "Company," which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to_________ ________________________________________________________________________________ or registered assigns, the principal sum of_____________________________________ on the Stated Maturity Date shown above and to pay interest thereon at the Interest Rate shown above from the Original Issue Date shown above or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually on June 15 and December 15 of each year (each an "Interest Payment Date") (unless other Interest Payment Dates are specified on the face hereof until the principal hereof is paid or made available for payment and at Maturity; provided, however, that any payment of principal (and premium, if any) or interest to be made on any Interest Payment Date or on a date of Maturity that is not a Business Day shall be made on the next succeeding Business Day with the same force and effect as it made on the Interest Payment Date or at Maturity, as the case may be, and no additional interest shall accrue as a result of such delayed payment. For purposes of this Security, "Business Day" means any day, other than a Saturday or Sunday, that meets each of the following applicable requirements: the day is (a) not a day on which banking institutions are authorized or required by law or regulation to be closed in The City of New York and (b) if the Specified Currency shown above is not U.S. dollars, (i) not a day on which banking institutions are authorized or required by law or regulation to close in the financial center of the country issuing the Specified Currency (which, in the case of European Currency Units, shall be Brussels, Belgium) and (ii) a day on which banking institutions in such financial center are carrying out transactions in such Specified Currency. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the May 31 or November 30 (unless other Regular Record Dates are specified on the face hereof) (whether or not a Business Day), as the case may be, next preceding 3 such Interest Payment Date; provided, however, that, in the case of a Security originally issued between a Regular Record Date and the initial Interest Payment Date relating to such Security, interest for the period beginning on the Original Issue Date and ending on such initial Interest Payment Date shall be paid on such initial Interest Payment Date to the Person to whom such Security shall have been originally issued; provided, further, that, in the case of a Global Security originally issued between a Regular Record Date and the initial Interest Payment Date relating to such Security, interest for the period beginning on the Original Issue Date and ending on such initial Interest Payment Date shall be paid on the Interest Payment Date following the next succeeding Regular Record Date to the registered Holder on such next succeeding Regular Record Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than ten days prior to such Special Record Date, or be paid at any time in any other lawful manner, all as more fully provided in said Indenture. All payments in respect of this Security will be made in U.S. dollars regardless of the Specified Currency shown above unless the Holder hereof makes the election described below. If the Specified Currency shown above is other than U.S. dollars, the Company or its agent will arrange to convert all payments in respect hereof into U.S. dollars in the manner described on the reverse hereof; provided, however, that the Holder hereof may, if so indicated above, elect to receive all payments in such Specified Currency by delivery of a written request to the Company's co-paying agent (the "Co-Paying Agent") in The City of New York, which must be received by the Co-Paying Agent on or prior to the applicable record date or at least fifteen calendar days prior to Maturity, as the case may be; provided, further, that, if the Holder of this Security elects to receive all such payments in a Specified Currency that is replaced by a single European currency (expected to be named the euro), the amount of principal of, premium, if any, or interest payable on any Security denominated in such currency shall be determined in the new single European currency in conformity with legally applicable measures taken pursuant to, or by virtue of, the treaty establishing the European Community, as amended by the treaty on European Union. Such election will remain in effect unless and until changed by written notice to the Co-Paying Agent, but the Co-Paying Agent must receive written notice of any such change on or prior to the applicable record date or at least fifteen calendar days prior to Maturity, as the case may be. Until the Securities are paid or payment therefor is provided for, the Company will at all times maintain a Co-Paying Agent in The City of New York capable of performing the duties described herein to be performed by the Co-Paying Agent. The Company has appointed State Street Bank and Trust Company, N.A., New York, New York as Co-Paying Agent. If the Company determines that the Specified Currency is not available for making payments in respect hereof due to the imposition of exchange controls or other circumstances beyond the Company's control, or is no longer used by the government of the country issuing such currency or for the settlement of transaction by public institutions of or within the international community, then the Holder hereof may not so elect to receive payments in the 4 Specified Currency and any such outstanding election shall be automatically suspended, until the Company determines that the Specified Currency is again available for making such payments. In the event of an official redenomination of the Specified Currency shown above, the obligations of the Company with respect to payments on this Security shall, in all cases, be deemed immediately following such redenomination to provide for payment of that amount of redenominated currency representing the amount of such obligations immediately before such redenomination. In no event shall any adjustment be made to any amount payable hereunder as a result of any change in the value of the Specified Currency shown above relative to any other currency due solely to fluctuations in exchange rates. Unless otherwise shown above, payment of interest on this Security (other than at Maturity) will be made by check (from an account at a bank outside the United States if such check is payable in a currency other than U.S. dollars) mailed to the registered address of the Person entitled thereto; provided that, if the Holder hereof is the Holder of U.S. $10,000,000 or more in aggregate principal amount of Securities of like tenor and term (or the equivalent thereof in a Specified Currency other than U.S. dollars determined as provided on the reverse hereof), such interest payments will be made in immediately available funds, but only if appropriate instructions have been received in writing by the Co-Paying Agent on or prior to the applicable record date. Simultaneously with any election by the Holder hereof to receive payments in respect hereof in the Specified Currency (if other than U.S. dollars), such Holder may, if applicable, provide appropriate instructions to the Co-Paying Agent, and all such payments will be made in immediately available funds to an account maintained by the payee with a bank located outside the United States. Unless otherwise specified above, the principal hereof (and premium, if any) and interest hereon payable at Maturity will be paid to the Holder on the date of Maturity in immediately available funds (payable to an account maintained by the payee with a bank located outside the United States if payable in a Specified Currency other than U.S. dollars) upon surrender of this Security at the office of the Co-Paying Agent maintained for that purpose in The City and State of New York (or at such other location as may be specified above), provided that this Security is presented to the Co-Paying Agent in time for the Co-Paying Agent to make such payments in accordance with its normal procedures. The Company will pay any administrative costs imposed by banks in connection with making payments in immediately available funds, but any tax, assessment or governmental charge imposed upon payments will be borne by the Holders of the Securities in respect of which such payments are made. Interest on this Security, if any, will be computed on the basis of a 360-day year of twelve 30-day months. If the registered owner of this Security (as indicated above) is the Depository or a nominee of the Depository, this Security is a Global Security and the following legend is applicable except as specified on the reverse hereof: THIS GLOBAL SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITORY OR BY A NOMINEE OF THE DEPOSITORY TO THE DEPOSITORY OR ANOTHER NOMINEE OF THE DEPOSITORY OR BY THE 5 DEPOSITORY OR ANY SUCH NOMINEE TO A SUCCESSOR OF THE DEPOSITORY OR A NOMINEE OF SUCH SUCCESSOR. REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE. Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed under its corporate seal. Dated: UNITED TECHNOLOGIES CORPORATION By: ------------------------------------ Vice President, Treasurer Attest: -------------------------------- Secretary TRUSTEE'S CERTIFICATE OF AUTHENTICATION This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture. STATE STREET BANK AND TRUST COMPANY As Trustee By: ------------------------------------ Authorized Officer 6 [Reverse of Security] UNITED TECHNOLOGIES CORPORATION MEDIUM-TERM NOTES, SERIES B Section 1. General. This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of April 1, 1990, as it may be supplemented from time to time (herein called the "Indenture"), between the Company and State Street Bank and Trust Company (as successor to The Connecticut National Bank), as Trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series set forth on the face hereof, unlimited in aggregate principal amount. Section 2. Payments. If the Specified Currency is other than U.S. dollars, the amount of any U.S. dollar payment to be made in respect hereof will be determined by the Exchange Rate Agent specified on the face hereof or a successor thereto (the "Exchange Rate Agent") based on the indicative quotation in The City of New York selected by such Exchange Rate Agent at approximately 11:00 a.m., New York City time, on the second Business Day preceding the applicable payment date that yields the largest number of U.S. dollars upon conversion of the Specified Currency. Such selection shall be made, as specified on the face hereof, from among the quotations from three recognized foreign exchange dealers in The City of New York selected by the Exchange Rate Agent and approved by the Company (one of which may be the Exchange Rate Agent) for the purchase by the quoting dealer, for settlement on such payment date, of the Specified Currency for U.S. dollars. If no such bid quotations are available, payments will be made in the Specified Currency unless such Specified Currency is unavailable as provided below. If the Specified Currency is other than U.S. dollars and the Specified Currency is unavailable due to the imposition of exchange controls or to other circumstances beyond the Company's control, the Company will be entitled to make payments in U.S. dollars on the basis of the noon buying rate in The City of New York for cable transfers in the Specified Currency as certified for customs purposes by the Federal Reserve Bank of New York (the "Market Exchange Rate") for such Specified Currency on the second Business Day prior to the applicable payment date. In the event such Market Exchange Rate is not then available, the Company will be entitled to make payments in U.S. dollars (i) if such Specified Currency is not a composite currency, on the basis of the most recently available Market Exchange Rate for such Specified Currency or (ii) if such Specified Currency is a composite currency, in an amount determined by the Exchange Rate Agent to be the sum of the results obtained by multiplying the number of units of each component currency of such composite currency, as of the most recent date on which such composite currency was used, by the Market Exchange Rate for such component currency on the second Business Day prior to such 7 payment date (or if such Market Exchange Rate is not then available, by the most recently available Market Exchange Rate for such component currency). From the start of the third stage of European Economic and Monetary Union, payments on this Security that are required to be made in ECU will be payable in euro at the rate of one euro for one ECU, and the provisions discussed in this paragraph will not result in payment in U.S. dollars in such circumstances unless euros are no longer used in the European Monetary System. All currency exchange costs will be borne by the Company unless the Holder of this Security has made an election to receive all payments in a Specified Currency other than U.S. dollars. In that case, the Holder of this Security shall bear its pro rata portion of currency exchange costs, if any, with all other electing Holders by deductions from payments otherwise due. Each payment of interest hereon shall include interest accrued through the day before the Interest Payment Date or Maturity, as the case may be. References herein to "U.S. dollars" or "U.S.$" or "$" are to the currency of the United States of America. Section 3. Redemption. If so specified on the face hereof, the Company may at its option redeem this Security in whole or from time to time in part on or after the date designated as the Initial Redemption Date on the face hereof at prices declining from a specified premium, if any, to par together with accrued interest to the Redemption Date. The Company may exercise such option by causing the Trustee to mail, first class postage prepaid, a notice of such redemption at least 30 but not more than 60 days prior to the Redemption Date, setting forth the applicable redemption price, Redemption Date, and principal amount of this Security to be redeemed. In the event of redemption of this Security in part only, a new Security or Securities for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. If less than all of the Securities with like tenor and terms to this Security are to be redeemed, the Securities to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem fair and appropriate. Section 4. Optional Repayment. If so specified on the face hereof, this Security will be repayable prior to the Stated Maturity Date at the option of the Holder on the Optional Repayment Dates shown on the face hereof at the Optional Repayment Prices shown on the face hereof together with accrued interest to the applicable Optional Repayment Date. In order for this Security to be repaid, the Company must receive at least 30 but not more than 45 days prior to an Optional Repayment Date this Security with the form below entitled "Option to Elect Repayment" duly completed. Any tender of this Security for repayment shall be irrevocable, except as otherwise provided in Sections 5 and 6 hereof. The repayment option may be exercised by the Holder of this Security for less than the entire principal amount of the Security provided that the principal amount of the Security remaining outstanding after repayment is an authorized denomination. Upon such partial repayment, this Security shall be cancelled and a new Security or Securities for the remaining principal amount hereof shall be issued in the name of the Holder of this Security. 8 Section 5. Optional Interest Reset. If so specified on the face hereof, the interest rate on this Security may be reset by the Company on the date or dates specified on the face hereof (each an "Optional Reset Date"). The Company may exercise such option with respect to this Security by notifying the Trustee of such exercise at least 50 but not more than 60 days prior to the Optional Reset Date for this Security. Not later than 40 days prior to each Optional Reset Date, the Trustee will mail to the Holder of this Security a notice (the "Reset Notice"), first class postage prepaid, setting forth (i) the election of the Company to reset the interest rate, (ii) such new interest rate and (iii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date or if there is no such next Optional Reset Date, to the Stated Maturity Date of this Security (each such period a "Subsequent Interest Period"), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during the Subsequent Interest Period. Notwithstanding the foregoing, not later than 20 days prior to the Optional Reset Date, the Company may, at its option, revoke the interest rate provided for in the Reset Notice and establish a higher interest rate for the Subsequent Interest Period commencing on such Optional Reset Date by causing the Trustee to mail notice of such higher interest rate to the Holder of this Security. Such Notice shall be irrevocable. All Securities with respect to which the interest rate is reset on an Optional Reset Date will bear such higher interest rate, whether or not tendered for repayment, as described below. If the Company elects to reset the interest rate, the Holder of this Security will have the option to elect repayment by the Company of the principal of this Security on any Optional Reset Date at a price equal to the principal amount hereof plus any accrued interest to such Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the Holder must follow the procedures set forth above for optional repayment except that the period for delivery of this Security or notification to the Trustee shall be at least 25 but not more than 35 days prior to such Optional Reset Date and except that, if the Holder has tendered this Security for repayment pursuant to the Reset Notice, the Holder may, by written notice to the Trustee, revoke any such tender for repayment until the close of business on the tenth day prior to such Optional Reset Date. Section 6. Optional Extension of Maturity. If so specified on the face hereof, the Stated Maturity Date of this Security may be extended at the option of the Company for the period or periods specified on the face hereof (each an "Extension Period") up to but not beyond the date (the "Final Maturity Date") set forth on the face hereof. The Company may exercise such option with respect to this Security by notifying the Trustee of such exercise at least 50 but not more than 60 days prior to the Stated Maturity Date of this Security in effect prior to the exercise of such option (the "Original Stated Maturity Date"). If the Company exercises such option, the Trustee will mail to the Holder of this Security not later than 40 days prior to the Original Stated Maturity Date a notice (the "Extension Notice"), first class postage prepaid, indicating (i) the election of the Company to extend the Stated Maturity Date, (ii) the new Stated Maturity Date, (iii) the interest rate applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period, including the date or dates on which or the period or periods during which and the 9 price or prices at which such redemption may occur during the Extension Period. Upon the Trustee's mailing of the Extension Notice, the Stated Maturity Date of this Security shall be extended automatically and, except as modified by the Extension Notice and as described in the next paragraph, this Security will have the same terms as prior to the mailing of such Notice. Notwithstanding the foregoing, not later than 20 days prior to the Original Stated Maturity Date of this Security the Company may, at its option, revoke the interest rate provided for in the Extension Notice and establish a higher interest rate for the Extension Period by causing the Trustee to mail notice of such higher interest rate, first class postage prepaid, to the Holder of this Security. Such notice shall be irrevocable. All Securities with respect to which the Stated Maturity Date is extended will bear such higher interest rate for the Extension Period, whether or not tendered for repayment as described below. If the Company elects to extend the Stated Maturity Date of this Security, the Holder will have the option to elect repayment of this Security by the Company on the Original Stated Maturity Date at a price equal to the principal amount hereof, plus any accrued interest to such date. In order to obtain repayment on the Original Stated Maturity Date once the Company has extended the Stated Maturity Date hereof, the Holder must follow the procedures set forth above for optional repayment except that the period for delivery of this Security or notification to the Trustee shall be at least 25 but not more than 35 days prior to the Original Stated Maturity Date and except that, if the Holder has tendered this Security for repayment pursuant to an Extension Notice, the Holder may by written notice to the Trustee revoke any such tender for repayment until the close of business on the tenth day prior to the Original Stated Maturity Date. Section 7. Sinking Fund. Unless otherwise specified on the face hereof, this Security will not be subject to any sinking fund. Section 8. Discount Securities. If this Security is a Discount Security, the amount payable in the event of redemption by the Company, repayment at the option of the Holder or acceleration of Maturity, in lieu of the principal amount due at the Stated Maturity hereof, shall be equal to the sum of (i) unpaid interest if any, on this Security accrued from the date of issue to the date of such redemption, repayment or acceleration of maturity, as the case may be, and (ii) the Amortized Face Amount of this Security as of the date of such redemption, repayment or acceleration. The "Amortized Face Amount" of this Security shall be the amount equal to (a) the Issue Price (as set forth on the face hereof) plus (b) that portion of the difference between the Issue Price and the principal amount hereof that has accrued at the Yield to Maturity (as set forth on the face hereof) (computed in accordance with generally accepted United States bond yield computation principles) at the date as of which the Amortized Face Amount is calculated, but in no event shall the Amortized Face Amount of the Security exceed its stated principal amount. Section 9. Modification and Waivers; Obligation of the Company Absolute. The Indenture permits, with exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series 10 to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of not less than a majority in aggregate principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of the Company on this Security and (b) certain restrictive covenants and the related defaults and Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Security, unless otherwise specified on the face hereof. Section 11. Authorized Denominations. The Securities of this series are issuable only in global or certificated registered form, without coupons, and, unless otherwise specified above (and other than Global Securities), in denominations of $100,000 and any integral multiple of $1,000 in excess thereof.

In such case, the Company will issue Securities in certificated form in exchange for each Global Security. In addition, the Company may at any time determine not to have Securities represented by a Global Security and, in such event, will issue Securities in certificated form in exchange for the Global Security representing such Security. In addition, if there shall have occurred and be continuing an Event of Default, the Company will issue Securities in certificated form in exchange for each Global Security.
