     Global Note in whole, but not in part, to the Depositary, its successor or
     their respective nominees. Interests of beneficial owners in a Global Note
     may be transferred in accordance with the rules and procedures of the
     Depositary and the provisions of Section 207. In addition, U.S. Physical
     Notes and Offshore Physical Notes shall be transferred to all beneficial
     owners in exchange for their beneficial interests in the U.S. Global Notes
     or the Offshore Global Notes, respectively, if (i) the Depositary notifies
     the Company that it is unwilling or unable to continue as Depositary for
     the U.S. Global Notes or the Offshore Global Notes, as the case may be, and
     a successor depositary is not appointed by the Company within 90 days of
     such notice or (ii) an Event of Default has occurred and is continuing and
     the Security Registrar has received a request to the foregoing effect from
     the Depositary.

          (c)  Any beneficial interest in one of the Global Notes that is
     transferred to a Person who takes delivery in the form of an interest in
     the other Global Note will, upon transfer, cease to be an interest in such
     Global Note and become an interest in the other Global Note and,
     accordingly, will thereafter be

     subject to all transfer restrictions, if any, and other procedures
     applicable to beneficial interests in such other Global Note for as long as
     it remains such an interest.

          (d)  In connection with any transfer of a portion of the beneficial
     interests in a U.S. Global Note or Offshore Global Note to beneficial
     owners pursuant to paragraph (b) of this Section, the Security Registrar
     shall reflect on its books and records the date and a decrease in the
     principal amount of the U.S. Global Notes or Offshore Global Notes, as the
     case may be, in an amount equal to the principal amount of the beneficial
     interest in such Global Notes to be transferred, and the Company shall
     execute, and the Trustee shall authenticate and deliver, one or more U.S.
     Physical Notes or Offshore Physical Notes, as the case may be, of like
     tenor and amount.

          (e)  In connection with the transfer of the entire U.S. Global Note or
     Offshore Global Note to beneficial owners pursuant to paragraph (b) of this
     Section, the U.S. Global Note or Offshore Global Note, as the case may be,
     shall be deemed to be surrendered to the Trustee for cancellation, and the
     Company shall execute, and the Trustee shall authenticate and deliver, to
     each beneficial owner identified by the Depositary in exchange for its
     beneficial interest in the U.S. Global Note or Offshore Global Note, as the
     case may be, an equal aggregate principal amount of U.S. Physical Notes or
     Offshore Physical Notes, as the case may be, of authorized denominations.

          (f)  Any U.S. Physical Note delivered in exchange for an interest in
     the U.S. Global Note pursuant to paragraph (b), (d) or (e) of this Section
     shall, except as otherwise provided by paragraph (e) of Section 207, bear
     the legend regarding transfer restrictions applicable to the U.S. Physical
     Note set forth in Section 204.

          (g)  Any Offshore Physical Note delivered in exchange for an interest
     in the Offshore Global Note pursuant to paragraph (b), (d) or (e) of this
     Section shall, except as otherwise provided by paragraph (e) of Section
     207, bear the legend regarding transfer restrictions applicable to the
     Offshore Physical Note set forth in Section 204.

          (h)  The registered holder of a Global Note may grant proxies and
     otherwise authorize any Person,

     including Agent Members and Persons that may hold interests through Agent
     Members, to take any action which a Holder is entitled to take under this
     Indenture or the Notes.

          (i)   Beneficial owners of interests in a U.S. Global Note may receive
     U.S. Physical Notes (which shall bear the Private Placement Legend if
     required by Section 204) in accordance with the procedures of the
     Depositary. In connection with the execution, authentication and delivery
     of such U.S. Physical Notes, the Security Registrar shall reflect on its
     books and records a decrease in the principal amount of the relevant U.S.
     Global Note equal to the principal amount of such U.S. Physical Notes and
     the Company shall execute and the Trustee shall authenticate and deliver
     one or more U.S. Physical Notes having an equal aggregate principal amount.

         acknowledges that it has received such information regarding the
         Company as it has requested pursuant to Rule 144A or has determined not
         to request such information and that it is aware that the transferor is
         relying upon its foregoing representations in order to claim the
         exemption from registration provided by Rule 144A or (y) an interest in

         an Offshore Global Note or Offshore Physical Note pursuant to Section

         unless such transfer complies with Section 207(b) or Section 207(d), as
         the case may be; and

               (ii) after such removal, the Security Registrar shall register

         certification.

         (d)   Transfers to Non-U.S. Persons at Any Time. The following

     Person:

               (i)  The Security Registrar shall register any proposed

<PAGE>

          on its books and records the date and a decrease in the principal
          amount of such U.S. Global Note in an amount equal to the principal
          amount of the beneficial interest in the U.S. Global Note to be
          transferred, and (b) if the proposed transferee is an Agent Member,
          upon receipt by the Security Registrar of instructions given in
          accordance with the Depositary's and the Security Registrar's
          procedures, the Security Registrar shall reflect on its books and

     Registrar shall deliver only Notes that bear the Private Placement Legend

     (c)(ii) of this Section 207 exist or (ii) there is delivered to the
     Security Registrar an Opinion of Counsel reasonably satisfactory to the
     Company and the Trustee to the effect that neither such legend nor the
     related restrictions on transfer are required in order to maintain
     compliance with the provisions of the Securities Act.

               (ii)  After a transfer of any Initial Notes during the period of
          the effectiveness of the Shelf Registration Statement with respect to
          such Initial Notes, all requirements pertaining to the Private
          Placement Legend on such Initial Notes shall cease to apply and the
          requirements that any such Initial Notes be issued in global form
          shall continue to apply.

          (f)  General. By its acceptance of any Note bearing the Private

     Placement Legend, each Holder of such a Note acknowledges the restrictions
     on transfer of such Note set forth in this Indenture and in the Private
     Placement Legend and agrees that it will transfer such Note only as
     provided in this Indenture. The Security Registrar shall not register a
     transfer of
<PAGE>

                                                                              15

     any Note unless such transfer complies with the restrictions on transfer of
     such Note set forth in this Indenture. In connection with any transfer of
     Notes, each Holder agrees by its acceptance of the Notes to furnish the
     Security Registrar or the Company such certifications, legal opinions or
     other information as either of them may reasonably require to confirm that
     such transfer is being made pursuant to an exemption from, or a transaction
     not subject to, the registration requirements of the Securities Act;
     provided that the Security Registrar shall not be required to determine
     --------
     (but may conclusively rely on a determination made by the Company with
     respect to) the sufficiency of any such certifications, legal opinions or
     other information.

          The Security Registrar shall retain copies of all letters, notices and
     other written communications received pursuant to Section 305 or this
     Section 207 in accordance with its customary procedures. The Company shall
     have the right to inspect and make copies of all such letters, notices or
     other written communications at any reasonable time upon the giving of
     reasonable written notice to the Security Registrar.

          Section 208. Issuance of Additional Notes. The Company shall be
                       ----------------------------
     entitled to issue Additional Notes under this Indenture which shall have
     identical terms as the Initial Notes issued on the Notes Closing Date,
     other than with respect to the date of issuance and issue price. The
     Initial Notes issued on the Notes Closing Date, any Additional Notes and
     all Exchange Notes issued in exchange therefor shall be treated as a single
     class for all purposes under this Indenture.

          With respect to any Additional Notes, the Company shall set forth in a
     resolution of the Board of Directors and an Officers' Certificate, a copy
     of each which shall be delivered to the Trustee, the following information:

         to be authenticated and
         delivered pursuant to this Indenture;

                  (2) the issue price, the issue date and the CUSIP number of
         such Additional Notes; provided, however, that no Additional Notes may
                                --------  -------
         be issued at a price that would cause such Additional Notes to have
         "original issue discount" within the meaning of Section 1273 of the
         Code; and

<PAGE>

                                                                              16

                  (3) whether such Additional Notes shall be Notes that bear or
         are required to bear the legend set forth in Section 204(a) and issued
         in the form of Initial Notes as set forth in Exhibit A or shall be
         issued in the form of Exchange Notes as set forth in Exhibit B."

         SECTION 4. Amendment to Article Three. The third paragraph of Section
                    --------------------------
 305 of Article Three of the Indenture is hereby supplemented and amended,
 solely with respect to the Notes, to read in its entirety as follows:

     series of Notes may be exchanged for other Securities of such series of any
     authorized denominations, of a like aggregate principal amount and Stated
     Maturity and of like tenor and terms (including an exchange of Notes for
     Exchange Notes), upon surrender of the Notes to be exchanged at such office
     or agency. Whenever any Notes are so surrendered for exchange, the Company
     shall execute, and the Trustee shall authenticate and deliver, the Notes
     which the noteholder making the exchange is entitled to receive; provided,
                                                                      --------
     that no exchanges of Notes for Exchange Notes shall occur until a
     Registration Statement shall have been declared effective by the Commission
     (confirmed in an Officers' Certificate delivered to the Trustee) and that
     any Notes that are exchanged for Exchange Notes shall be canceled by the
     Trustee."

                       [Floating Rate] [[  ]%] Note Due [  ]

 1.  Principal and Interest.

          Raytheon Company, a corporation duly organized and existing under the
laws of the State of Delaware (herein called the "Company", which term includes
any successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to Cede & Co., or registered assigns, the
principal sum of [       ] Dollars [($      )] on March 1, [      ], [and to pay
interest thereon from, and including, March 7, 2000 to, but excluding, June 1,
2000, at a rate per annum equal to 6.75% (the "Initial Interest Rate") and
thereafter at a rate per annum equal to LIBOR (as defined below) plus .63%,
until the principal hereof is paid or made available for payment, payable
quarterly in arrears on March 1, June 1, September 1 and December 1, commencing
on June 1; provided, however, that if any Interest Payment Date (other than the
           --------  -------
Stated Maturity or a redemption date) would fall on a day that is not a Business
Day, such Interest Payment Date will be the following day that is a Business
Day, except that if such Business Day is in the next succeeding calendar month,
such Interest Payment Date shall be the next preceding Business Day. If the
Stated Maturity or a redemption date falls on a day that is not a Business Day,
the payment of principal and interest on this Note due on such date will be made
on the next succeeding Business Day, and no interest on such payment shall
accrue for the period from and after the Stated Maturity or such redemption
date.] [and to pay interest thereon from March 7, 2000, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
semiannually in arrears on March 1 and September 1 in each year, commencing
September 1, 2000, at the rate of [ ]% per annum, until the principal hereof is
paid or made available for payment, and (to the extent that the payment of such
interest shall be legally enforceable) at the rate of [ ]% per annum on any
overdue principal and premium and on any overdue installment of interest. 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 Note (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 February 15 or August 15 (whether or not a Business Day), as the case may
be, next
                                      A-5
<PAGE>

preceding such Interest Payment 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 Note
(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 Notes not less than
10 days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in said Indenture.

          Payment of the principal of and interest on this Note will be made at
the office or agency of the Company maintained for that purpose in New York, New
York, in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts; provided,
                                                                 --------
however, that at the option of the Company payment of interest may be made by
-------
check mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register.

          [The rate of interest on this Note will be reset quarterly (the
 "Interest Reset Period," and the first day of each Interest Reset Period being
 an "Interest Reset Date"). The Interest Reset Dates will be March 1, June 1,
 September 1 and December 1, commencing June 1, 2000; provided, however, that
 the interest rate in effect from the date of original issue to the first
 Interest Reset Date will be the Initial Interest Rate. If any Interest Reset
 Date would otherwise be a day that is not a Business Day, such Interest Reset
 Date shall be postponed to the next succeeding Business Day, except that if
 such Business Day is in the next succeeding calendar month, such Interest Reset
 Date shall be the next preceding Business Day. As used herein, "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 and that is also a day on which
 dealings in deposits in U.S. dollars are transacted in the London interbank
 market.

          Interest payments on this Note shall be the amount of interest accrued
 from, and including, the date of original issue or from, and including, the
 last date to which interest has been paid to, but excluding, the Interest
 Payment Date, the Stated Maturity or a redemption date, as the case may be.

                                      A-6
<PAGE>

     Accrued interest on this Note shall be calculated by multiplying the
principal amount hereof by an accrued interest factor. Such accrued interest
factor will be computed by adding the interest factors calculated for each day
in the period for which interest is being paid. The interest factor for each
such day is computed by dividing the interest rate applicable to such day by
360. All percentages used in or resulting from any calculation of the rate of
interest on this Note will be rounded, if necessary, to the nearest one-hundred-
thousandth of a percentage point (.0000001), with five one-millionths of a
percentage point rounded upward, and all dollar amounts used in or resulting
from such calculation will be rounded to the nearest cent, with one-half cent
rounded upward. The interest rate in effect on any Interest Reset Date will be
the applicable rate as reset on such date. The interest rate applicable to any
other day is the interest rate from the immediately preceding Interest Reset
Date (or, if none, the Initial Interest Rate).

          The "Interest Determination Date" pertaining to an Interest Reset Date
will be the second London Banking Day preceding such Interest Reset Date.
"London Banking Day" means any day on which dealings in deposits in U.S. dollars
are transacted in the London interbank market.

          "LIBOR" for each Interest Reset Date will be determined by The Bank
of New York (together with its successors and assigns as calculation agent for
this Note, the "Calculation Agent") as follows:

          (i)    As of each Interest Determination Date, the Calculation Agent
     will determine LIBOR as the rate for deposits in U.S. dollars for a period
     of three months, commencing on such Interest Determination Date, that
     appears on Page 3750 on Bridge Telerate Inc., or any successor page, at
     approximately 11:00 a.m., London time, on such Interest Determination Date.
     If no rate appears, LIBOR in respect of such Interest Determination Date
     will be determined as described in (ii) below.

          (ii)   With respect to an Interest Determination Date on which no rate
     appears, the Calculation Agent will request the principal London offices of
     each of four major reference banks in the London interbank market, as
     selected by the Calculation Agent (after consultation with the Company), to
     provide the Calculation Agent with its offered quotations for deposits in
     U.S. dollars for a period of three months, commencing on the second London
     Banking Day immediately following such Interest Determination Date, to
     prime

                                      A-7
<PAGE>

     banks in the London interbank market at approximately 11:00 a.m., London
     time, on such Interest Determination Date and in a principal amount that is
     representative of a single transaction in U.S. dollars in such market at
     such time. If at least two such quotations are provided, LIBOR will be the
     arithmetic mean of such quotations. If fewer than two quotations are
     provided, LIBOR in respect of that Interest Determination Date will be the
     arithmetic mean of the rates quoted at approximately 11:00 a.m., New York
     time, on the Interest Reset Date by three major banks in New York City
     selected by the Calculation Agent (after consultation with the Company) for
     loans in U.S. dollars to leading European banks, for a period of three
     months, commencing on the Interest Reset Date and in a principal amount
     that is representative of a single transaction in U.S. dollars in such
     market at such time; provided, however, that if the banks selected as
                          --------  -------
     aforesaid by the Calculation Agent are not quoting rates as mentioned in
     this sentence, LIBOR for such Interest Reset Period will be the same as
     LIBOR for the immediately preceding Interest Reset Period (or, if there was
     no such Interest Reset Period, the rate of interest payable on this Note
     for such Interest Reset Period shall be the Initial Interest Rate).]

          See paragraph 10 below for a description of circumstances under which
Additional Interest may accrue on this Note.

2.   Paying Agent and Registrar.
     --------------------------

          Initially, the Trustee will be the Paying Agent and the Security
Registrar with respect to this Note. The Company reserves the right at any time
to vary or terminate the appointment of any Paying Agent or Security Registrar,
to appoint additional or other Paying Agents and other Security Registrars and
to approve any change in the office through which any Paying Agent or Security
Registrar acts; provided that there will at all times be a Paying Agent in The
                --------
City of New York.

3.   Redemption.
     ----------

          [The Notes will not be redeemable.]

          [The Notes will be redeemable as a whole at any time or in part from
time to time, at the option of the Company, at a redemption price equal to the
greater of (i) 100% of the principal amount of such Notes and (ii) the sums of
the present values of the remaining scheduled

                                      A-8
<PAGE>

payments of principal and interest thereon from the redemption date to March 1,
[    ], discounted to the redemption date on a semiannual basis (assuming a 360-
day year consisting of twelve 30-day months) at the Treasury Rate plus [20][25]
basis points plus, in either case, any interest accrued but not paid to the date
of redemption. Notice of any redemption will be mailed at least 30 days but no
more than 60 days before the redemption date to each holder of the Notes to be
redeemed. Unless the Company defaults in payment of the redemption price, on and
after the redemption date interest will cease to accrue on the Notes or portions
thereof called for redemption. The Notes will not be subject to any sinking fund
provision.

          Notice of any redemption will be mailed at least 30 days but no more
than 60 days before the redemption date to each holder of the Notes to be
redeemed.

          Unless the Company defaults in payment of the redemption price, on and
after the redemption date interest will cease to accrue on the Notes or portions
thereof called for redemption.

          "Treasury Rate" means, with respect to any redemption date for the
Notes, (i) the yield, under the heading which represents the average for the
immediately preceding week, appearing in the most recently published statistical
release designated "H.15(519)" or any successor publication which is published
weekly by the Board of Governors of the Federal Reserve System and which
establishes yields on actively traded United States Treasury securities adjusted
to constant maturity under the caption "Treasury Constant Maturities," for the
maturity corresponding to the Comparable Treasury Issue (if no maturity is
within three months before or after the Maturity Date, yields for the two
published maturities most closely corresponding to the Comparable Treasury Issue
shall be determined and the Treasury Rate shall be interpolated or extrapolated
from such yields on a straight line basis, rounding to the nearest month) or
(ii) if such release (or any successor release) is not published during the week
preceding the calculation date or does not contain such yields, the rate per
annum equal to the semi-annual equivalent yield maturity of the Comparable
Treasury Issue, calculated using a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date. The Treasury Rate shall be calculated
on the third Business Day preceding the redemption date.

                                      A-9
<PAGE>

          "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Notes to be redeemed that would be utilized, at the
time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of such notes.

          "Independent Investment Banker" means one of the Reference Treasury
Dealers appointed by the Trustee after consultation with the Company.

          "Comparable Treasury Price" means, with respect to any redemption date
for the Notes, (i) the average of four Reference Treasury Dealer Quotations for
such redemption date, after excluding the highest and lowest such Reference
Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than four such
Reference Treasury Dealer Quotations, the average of all such quotations .

          "Reference Treasury Dealer" means each of Credit Suisse First Boston
Corporation, Morgan Stanley & Co. Incorporated and two other primary U.S.
Government securities dealers in New York City (each, a "Primary Treasury
Dealer") appointed by the Trustee in consultation with the Company; provided,
                                                                    --------
however, that if any of the foregoing shall cease to be a Primary Treasury
-------
Dealer, the Company shall substitute therefor another Primary Treasury Dealer.

          "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third business day preceding such redemption date.]

4.   Denominations; Transfer; Exchange.

 Manhattan, The City of New York, and in the manner and subject to the
 limitations provided in the Indenture.

                                     A-10
<PAGE>

          Upon due presentment for registration of transfer of this Note at the

York, a new Note or Notes of authorized denominations for a like aggregate

          No service charge shall be made for any such transfer or exchange, but

          Subject to the provisions of the Indenture, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name

the outstanding Securities of each series to be affected, to execute
supplemental indentures adding any provisions to or changing or eliminating any
of the provisions of the Indenture or modifying the rights of the Holders of the
Securities of such series to be affected, except that no such supplemental
indenture may, without the consent of all of the Holders of affected Securities,
among other things, change the fixed maturity of any Securities or reduce the
aforesaid percentage in principal amount of Securities of any series

                                     A-11

principal amount of the Outstanding Securities of any series on behalf of the
Holders of all Securities of such series to waive compliance by the Company with
certain provisions of the Indenture and certain past defaults and their
consequences with respect to such series under the Indenture. Any such consent
or waiver by the Holder of this Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether
or not notation of such consent or waiver is made upon this Note or such other
Note.

7.   Defaults and Remedies.
     ---------------------

          The Indenture provides that, if an Event of Default specified therein

either the Trustee or the Holders of 25% in aggregate principal amount of such
series of Securities (or 25% in aggregate principal amount of all outstanding
Securities under the Indenture, in the case of certain Events of Default
affecting all series of Securities under the Indenture) may declare the
principal of all such series of Securities to be due and payable.

          Events of Default in respect of the Securities of any series are
provided in the Indenture and include: (i) default in the payment of any
interest on any Security of that series when it becomes due and payable, and
continuance of such default for a period of 30 days; (ii) default in the payment

than

                                     A-12
<PAGE>

covenants or agreements included in the Indenture solely for the benefit of a
series or series of Securities thereunder other than that series) and
continuance of such default for a period of 60 days after either the Trustee or
the Holders of at least 25% of the principal amount of the Outstanding
Securities of that series have given written notice in the manner provided for
therein specifying such failure as provided in the Indenture; (v) certain events
of bankruptcy, insolvency or reorganization of the Company; and (vi) any other
Event of Default provided with respect to Securities of that series. If an Event

give the Holders of the Securities of such series notice of such default,
provided, however, that in the case of a default described in (iv) above, no
--------  -------
such notice to Holders shall be given until at least 30 days after the

          If an Event of Default with respect to the Securities of any series at
the time outstanding occurs and is continuing, either the Trustee or the Holders
of at least 25% of the aggregate principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series to be due and payable immediately. At any time after a declaration of
acceleration with respect to Securities of any series has been made, but before
a judgment or decree based on acceleration has been obtained, the Holders of a
majority of the aggregate principal amount of Outstanding Securities of that
series may, under certain circumstances, rescind and annul such acceleration.

          The Indenture provides that the Holders of a majority in aggregate
principal amount of the Outstanding Securities of each series may direct the
time, method and place of conducting proceedings for remedies available to the
Trustee or exercising any trust or power conferred on the Trustee in respect of
such series, subject to certain conditions.

8.   Authentication.
     --------------

          This Note shall not be valid until the Trustee or authenticating agent
signs the certificate of authentication on the other side of this Note.

9.   Defeasance.
     ----------

          The Indenture provides that the Company may elect either (i) to
defease and be discharged from any and all obligations in respect of a series of
Securities then outstanding (except for certain obligations to register the

                                     A-13
<PAGE>

transfer of or exchange of such series of Securities, replace stolen, lost or
mutilated Securities, maintain paying agencies and hold monies for payment in
trust) ("defeasance") or (ii) to be released from its obligations with respect
to such series of Securities under any covenants applicable to such series of
Securities which are determined pursuant to Section 301 of the Indenture to be
subject to covenant defeasance ("covenant defeasance"), and the occurrence of an
event described in clause (iv) under "Events of Default" above (insofar as with
respect to covenants subject to covenant defeasance) shall no longer be an Event
of Default, in the case of either (i) or (ii) if the Company deposits, in trust,
with the Trustee money or U.S. Government Obligations, which through the payment
of interest thereon and principal thereof in accordance with their terms will
provide money, in an amount sufficient, without reinvestment, to pay all the
principal of, premium, if any, and interest on such series of Securities on the
dates such payments are due (which may include one or more redemption dates
designated by the Company) and any mandatory sinking fund or analogous payments
thereon in accordance with the terms of such series of Securities.

10.  Exchange Offer; Registration Rights.
     -----------------------------------

          Pursuant to a Registration Rights Agreement, the Company will file
with the Commission and use its reasonable best efforts to cause to become
effective a Registration Statement with respect to an issue of Notes identical
in all material respects to the Notes and, upon becoming effective, to offer the
Holders of the Notes the opportunity to exchange their Initial Notes for the
Exchange Notes (the "Exchange Offer"). In the event that due to a change in
current interpretations by the Commission, the Company is not permitted to
effect such Exchange Offer, the Company will instead file a Shelf Registration
Statement covering resales by the holders of Notes and will use its reasonable
best efforts to cause such Shelf Registration Statement to become effective and
to keep such Shelf Registration Statement effective for two years from the Notes
Closing Date. The Company shall, in the event a Shelf Registration Statement is
filed, provide to each Holder of the Notes copies of the prospectus and notify
each such Holder when the Shelf Registration Statement has become effective. A
Holder that sells Notes pursuant to a Shelf Registration Statement generally
will be required to be named as a selling security holder in the related
prospectus and to deliver a current prospectus to purchasers, and will be
subject to certain of the civil liability provisions under the Securities Act in
connection with such sales. The Exchange Notes will be issued (i) under the
Indenture or

                                     A-14
<PAGE>

(ii) under an indenture substantially similar to the Indenture, which, in either
event, will provide that the Exchange Notes will not be subject to the transfer
restrictions described in the Indenture.

          Pursuant to the Registration Rights Agreement, the Company will use
its reasonable best efforts to: (i) file the Registration Statement or a Shelf
Registration Statement with the Commission within 150 days after the Notes
Closing Date, (ii) have such Registration Statement or Shelf Registration
Statement declared effective by the Commission within 180 days after the Notes
Closing Date and (iii) consummate the Exchange Offer and issue the Exchange
Notes in exchange for all Notes validly tendered in accordance with the terms of
the Exchange Offer within 210 days after the Notes Closing Date, or, in the
alternative, cause such Shelf Registration Statement to remain effective for two
years from the Notes Closing Date.

          If the Company fails to comply with the above provisions, additional
interest (the "Additional Interest") shall accrue on this Note as follows:

          (i)    If the Registration Statement or Shelf Registration Statement
          is not filed within 150 days following the Notes Closing Date, then
          commencing on the 151st day after the Notes Closing Date, Additional
          Interest shall accrue on the outstanding principal amount of this Note
          over and above the interest accruing at the rate specified on the face
          of this Note at a rate of .25% per annum; or

          (ii)   If a Registration Statement or Shelf Registration Statement is
          not declared effective within 180 days following the Notes Closing
          Date, then commencing on the 181st day after the Notes Closing Date,
          Additional Interest shall accrue on the outstanding principal amount
          of this Note over and above the interest accruing at the rate
          specified on the face of this Note at a rate of .25% annum; or

          (iii)  If either (A) the Company has not exchanged Exchange Notes for
          all Notes validly tendered in accordance with the terms of the
          Exchange Offer on or prior to 30 days after the date on which the
          Registration Statement was declared effective, or (B) if applicable,
          the Shelf Registration Statement has been declared effective but such
          Shelf Registration Statement ceases to be

                                     A-15
<PAGE>

          effective at any time prior to two years from the Notes Closing Date,
          then Additional Interest shall accrue on the outstanding principal
          amount of this Note over and above the interest accruing at the rate
          specified on the face of this Note at a rate of .25% per annum
          immediately following the (x) 31st day after such effective date, in
          the case of (A) above, or (y) the day such Shelf Registration
          Statement ceases to be effective in the case of (B) above;

provided, however, that the Additional Interest rate on this Note shall in no
--------  -------
event exceed .25% per annum; and, provided, further, that (1) upon the filing of
                                  --------  -------
the Registration Statement or Shelf Registration Statement (in the case of (i)
above), (2) upon the effectiveness of the Registration Statement or Shelf
Registration Statement (in the case of (ii) above), or (3) upon the exchange of
Exchange Notes for all Notes tendered or upon the effectiveness of the Shelf
Registration Statement which had ceased to remain effective prior to the
expiration of the holding period referred to in Rule 144(k) (in the case of
(iii) above), Additional Interest on this Note as a result of such clause (i),
(ii) or (iii) shall cease to accrue.

          Any amounts of Additional Interest due pursuant to clauses (i), (ii)
or (iii) above will be payable in cash, on the same original payment dates as
other interest due on this Note. The amount of Additional Interest due on this
Note will be determined by multiplying the applicable Additional Interest rate
by the outstanding principal amount of this Note, multiplied by a fraction, the
numerator of which is the number of days such Additional Interest rate was
applicable during such period (determined on the basis of a 360-day year
comprised of twelve 30-day months), and the denominator of which is 360.

          If the Company effects the Exchange Offer, the Company will be
entitled to close the Exchange Offer provided that the Company has accepted all
Notes theretofore validly tendered in accordance with the terms of the Exchange
Offer. Notes not tendered in the Exchange Offer shall bear interest at the same
rates in effect at the time of issuance of the Notes.

11.  Obligation To Pay Interest Absolute.
     -----------------------------------

          No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal and any premium of and

1.   Principal and Interest.
     ----------------------

          Raytheon Company, a corporation duly organized and existing under the
laws of the State of Delaware (herein called the "Company", which term includes
any successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to Cede & Co., or registered assigns, the
principal sum of [     ] Dollars [($       )] on March 1, [    ], [and to pay
interest thereon from, and including, March 7, 2000 to, but excluding, June 1,
2000, at a rate per annum equal to 6.75% (the "Initial Interest Rate") and
thereafter at a rate per annum equal to LIBOR (as defined below) plus .63%,
until the principal hereof is paid or made available for payment, payable
quarterly in arrears on March 1, June 1, September 1 and December 1, commencing
on June 1; provided, however, that if any Interest Payment Date (other than the
           --------  -------
Stated Maturity or a redemption date) would fall on a day that is not a Business
Day, such Interest Payment Date will be the following day that is a Business
Day, except that if such Business Day is in the next succeeding calendar month,
such Interest Payment Date shall be the next preceding Business Day. If the
Stated Maturity or a redemption date falls on a day that is not a Business Day,
the payment of principal and interest on this Exchange Note due on such date
will be made on the next succeeding Business Day, and no interest on such
payment shall accrue for the period from and after the Stated Maturity or such
redemption date.] [and to pay interest thereon from March 7, 2000, or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, semiannually in arrears on March 1 and September 1 in each year,
commencing September 1, 2000, at the rate of [    ]% per annum, until the
principal hereof is paid or made available for payment, and (to the extent that
the payment of such interest shall be legally enforceable) at the rate of [   ]%
per annum on any overdue principal and premium and on any overdue installment of
interest. 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 Exchange Note (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 February 15 or August 15 (whether or not a Business
Day), as the case may be, next preceding such Interest Payment Date.] Any such
interest
                                      B-4
<PAGE>

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 Exchange Note (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 Exchange Notes not less than 10 days prior to such Special
Record Date, or be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Exchange Notes may
be listed, and upon such notice as may be required by such exchange, all as more
fully provided in said Indenture.

          Payment of the principal of and interest on this Exchange Note will be
made at the office or agency of the Company maintained for that purpose in New
York, New York, in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be
--------  -------
made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register.

          [The rate of interest on this Exchange Note will be reset quarterly
(the "Interest Reset Period," and the first day of each Interest Reset Period
being an "Interest Reset Date"). The Interest Reset Dates will be March 1, June
1, September 1 and December 1, commencing June 1, 2000; provided, however, that
the interest rate in effect from the date of original issue to the first
Interest Reset Date will be the Initial Interest Rate. If any Interest Reset
Date would otherwise be a day that is not a Business Day, such Interest Reset
Date shall be postponed to the next succeeding Business Day, except that if such
Business Day is in the next succeeding calendar month, such Interest Reset Date
shall be the next preceding Business Day. As used herein, "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 and that is also a day on which
dealings in deposits in U.S. dollars are transacted in the London interbank
market.

          Interest payments on this Exchange Note shall be the amount of
interest accrued from, and including, the date of original issue or from, and
including, the last date to which interest has been paid to, but excluding, the
Interest Payment Date, the Stated Maturity or a redemption date, as the case may
be.

                                      B-5
<PAGE>

     Accrued interest on this Exchange Note shall be calculated by multiplying
the principal amount hereof by an accrued interest factor. Such accrued interest
factor will be computed by adding the interest factors calculated for each day
in the period for which interest is being paid. The interest factor for each
such day is computed by dividing the interest rate applicable to such day by
360. All percentages used in or resulting from any calculation of the rate of
interest on this Exchange Note will be rounded, if necessary, to the nearest
one-hundred-thousandth of a percentage point (.0000001), with five one-
millionths of a percentage point rounded upward, and all dollar amounts used in
or resulting from such calculation will be rounded to the nearest cent, with
one-half cent rounded upward. The interest rate in effect on any Interest Reset
Date will be the applicable rate as reset on such date. The interest rate
applicable to any other day is the interest rate from the immediately preceding
Interest Reset Date (or, if none, the Initial Interest Rate).

          The "Interest Determination Date" pertaining to an Interest Reset Date
will be the second London Banking Day preceding such Interest Reset Date.
"London Banking Day" means any day on which dealings in deposits in U.S. dollars
are transacted in the London interbank market.

          "LIBOR " for each Interest Reset Date will be determined by The Bank
of New York (together with its successors and assigns as calculation agent for
this Exchange Note, the "Calculation Agent") as follows:

               (i)  As of each Interest Determination Date, the Calculation
   Agent will determine LIBOR as the rate for deposits in U.S. dollars for a
   period of three months, commencing on such Interest Determination Date, that
   appears on Page 3750 on Bridge Telerate Inc., or any successor page, at
   approximately 11:00 a.m., London time, on such Interest Determination Date.
   If no rate appears, LIBOR in respect of such Interest Determination Date will
   be determined as described in (ii) below.

               (ii) With respect to an Interest Determination Date on which no
     rate appears, the Calculation Agent will request the principal London
     offices of each of four major reference banks in the London interbank
     market, as selected by the Calculation Agent (after consultation with the
     Company), to provide the Calculation Agent with its offered quotations for
     deposits in U.S. dollars for a period of three months, commencing on the
     second London Banking Day immediately following such Interest Determination
     Date, to prime
                                      B-6

         London time, on such Interest Determination Date and in a principal
         amount that is representative of a single transaction in U.S. dollars
         in such market at such time. If at least two such quotations are
         provided, LIBOR will be the arithmetic mean of such quotations. If

         commencing on the Interest Reset Date and in a principal amount that is
         representative of a single transaction in U.S. dollars in such market
         at such time; provided, however, that if the banks selected as
         aforesaid by the Calculation Agent are not quoting rates as mentioned
         in this sentence, LIBOR for such Interest Reset Period will be the same
         as LIBOR for the immediately preceding Interest Reset Period (or, if
         there was no such Interest Reset Period, the rate of interest payable
         on this Exchange Note for such Interest Reset Period shall be the
         Initial Interest Rate).]

2.   Paying Agent and Registrar.
     --------------------------

          Initially, the Trustee will be the Paying Agent and the Security

equal to the greater of (i) 100% of the principal amount of such Exchange Notes
and (ii) the sums of the present values of the remaining scheduled payments of
principal and interest thereon from the redemption date to March 1, [    ],
discounted to the redemption date on a semiannual basis (assuming a 360-day

                                      B-7
<PAGE>

year consisting of twelve 30-day months) at the Treasury Rate plus [20][25]
basis points plus, in either case, any interest accrued but not paid to the date
of redemption. Notice of any redemption will be mailed at least 30 days but no
more than 60 days before the redemption date to each holder of the Exchange
Notes to be redeemed. Unless the Company defaults in payment of the redemption
price, on and after the redemption date interest will cease to accrue on the
Exchange Notes or portions thereof called for redemption. The Exchange Notes
will not be subject to any sinking fund provision.

          Notice of any redemption will be mailed at least 30 days but no more
than 60 days before the redemption date to each holder of Exchange Notes to be
redeemed.

for the immediately preceding week, appearing in the most recently published
statistical release designated "H.15(519)" or any successor publication which is
published weekly by the Board of Governors of the Federal Reserve System and
which establishes yields on actively traded United States Treasury securities
adjusted to constant maturity under the caption "Treasury Constant Maturities,"
for the maturity corresponding to the Comparable Treasury Issue (if no maturity
is within three months before or after the Maturity Date, yields for the two
published maturities most closely corresponding to the Comparable Treasury Issue
shall be determined and the Treasury Rate shall be interpolated or extrapolated
from such yields on a straight line basis, rounding to the nearest month) or
(ii) if such release (or any successor release) is not published during the week
preceding the calculation date or does not contain such yields, the rate per
annum equal to the semi-annual equivalent yield maturity of the Comparable
Treasury Issue, calculated using a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date. The Treasury Rate shall be calculated
on the third Business Day preceding the redemption date.

          "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to

<PAGE>

remaining term of the Exchange Notes to be redeemed that would be utilized, at
the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of such notes.

          "Independent Investment Banker" means one of the Reference Treasury
Dealers appointed by the Trustee after consultation with the Company.

          "Comparable Treasury Price" means, with respect to any redemption date
for the Exchange Notes, (i) the average of four Reference Treasury Dealer
Quotations for such redemption date, after excluding the highest and lowest such
Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than
four such Reference Treasury Dealer Quotations, the average of all such
quotations.

          "Reference Treasury Dealer" means each of Credit Suisse First Boston
Corporation, Morgan Stanley & Co. Incorporated and two other primary U.S.
Government securities dealers in New York City (each, a "Primary Treasury
Dealer") appointed by the Trustee in consultation with the Company; provided,
                                                                    --------
however, that if any of the foregoing shall cease to be a Primary Treasury
-------
Dealer, the Company shall substitute therefor another Primary Treasury Dealer.

          "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third business day preceding such redemption date.]

among other things, change the fixed maturity of any Securities or reduce the
aforesaid percentage in principal amount of Securities of any series the consent
of the Holders of which is required for any such supplemental indenture.

          The Indenture also permits the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series on behalf of the
Holders of all Securities of such series to waive compliance by the Company with
certain provisions of the Indenture and certain past defaults and their
consequences with respect to such series under the Indenture. Any such consent
or waiver by the Holder of this Exchange Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Exchange Note and of any
Note issued upon the registration of transfer hereof or in exchange hereof or in
lieu hereof, whether or not notation of such consent or waiver is made upon this
Exchange Note or such other Note.

          The Indenture provides that, if an Event of Default specified therein

series of Securities (or 25% in aggregate principal amount of all outstanding
Securities under the Indenture, in the case of certain Events of Default
affecting all series of Securities under the Indenture) may declare the
principal of all such series of Securities to be due and payable.

                                     B-11
<PAGE>

          Events of Default in respect of the Securities of any series are
provided in the Indenture and include: (i) default in the payment of any
interest on any Security of that series when it becomes due and payable, and
continuance of such default for a period of 30 days; (ii) default in the payment
of principal of, or premium, if any, on any Security of that series when it
shall become due and payable; (iii) failure to deposit any sinking fund payment
when and as due by the terms of a Security of that series; (iv) failure to
perform any other covenants or agreements of the Company in the Indenture (other
than covenants or agreements included in the Indenture solely for the benefit of
a series or series of Securities thereunder other than that series) and
continuance of such default for a period of 60 days after either the Trustee or
the Holders of at least 25% of the principal amount of the Outstanding
Securities of that series have given written notice in the manner provided for
therein specifying such failure as provided in the Indenture; (v) certain events
of bankruptcy, insolvency or reorganization of the Company; and (vi) any other
Event of Default provided with respect to Securities of that series. If an Event
of Default occurs with respect to Securities of any series, the Trustee shall
give the Holders of the Securities of such series notice of such default,
provided, however, that in the case of a default described in (iv) above, no
--------  -------
such notice to Holders shall be given until at least 30 days after the
occurrence thereof.

          If an Event of Default with respect to the Securities of any series at
the time Outstanding occurs and is continuing, either the Trustee or the Holders
of at least 25% of the aggregate principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series to be due and payable immediately. At any time after a declaration of
acceleration with respect to Securities of any series has been made, but before
a judgment or decree based on acceleration has been obtained, the Holders of a
majority of the aggregate principal amount of outstanding Securities of that
series may, under certain circumstances, rescind and annul such acceleration.

          The Indenture provides that the Holders of a majority in aggregate
principal amount of the Outstanding Securities of each series may direct the
time, method and place of conducting proceedings for remedies available to the
Trustee or exercising any trust or power conferred on the Trustee in respect of
such series, subject to certain conditions.

transfer of or exchange of such series of Securities, replace stolen, lost or
mutilated Securities, maintain paying agencies and hold monies for payment in

to such series of Securities under any covenants applicable to such series of
Securities which are determined pursuant to Section 301 of the Indenture to be
subject to covenant defeasance ("covenant defeasance"), and the occurrence of an
event described in clause (iv) under "Events of Default" above (insofar as with
respect to covenants subject to covenant defeasance) shall no longer be an Event
of Default, in the case of either (i) or (ii) if the Company deposits, in trust,
with the Trustee money or U.S. Government Obligations, which through the payment
of interest thereon and principal thereof in accordance with their terms will
provide money, in an amount sufficient, without reinvestment, to pay all the
principal of, premium, if any, and interest on such series of Securities on the

Ladies and Gentlemen:

          In connection with our proposed purchase of the Notes, we confirm
that:

          1.   We understand that any subsequent transfer of the Notes is
subject to certain restrictions and conditions set forth in the Indenture dated
as of July 3, 1995, as supplemented and amended by the Supplemental Indenture
dated as of March 7, 2000 (as so supplemented and amended, the "Indenture"),
relating to the Notes, and the undersigned agrees to be bound by, and not to
resell, pledge or otherwise transfer the Notes except in compliance with, such
restrictions and conditions and the Securities Act of 1933 (the "Securities
Act").

          2.   We understand that the offer and sale of the Notes have not been
registered under the Securities Act, and that the Notes may not be offered or
sold except as permitted in the following sentence. We agree, on our own behalf
and on behalf of any accounts for which we are acting as hereinafter stated,
that if we should sell any Notes, we will do so only (A) to the Company, or any
subsidiary thereof, (B) in accordance with Rule 144A under the Securities Act to
a "qualified institutional buyer" (as defined therein), (C) to an institutional
"accredited investor" (as defined below) that, prior to such transfer, furnishes
(or has furnished on its behalf by a U.S. broker-dealer) to you and to the
Company a signed letter substantially in the form of this letter, (D) outside
the United States in accordance with Rule 904 of Regulation S under the
Securities Act, (E) pursuant to the exemption from registration provided by Rule

          4.   We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Notes and any
accounts for which we are acting are each able to bear the economic risk of our
or its investment.

          5.   We are acquiring the Notes purchased by us for our own account or
for one or more accounts (each of which is an institutional "accredited
investor") as to each of which we exercise sole investment discretion.
