                              FINANCIAL STATEMENTS
                          TO ACCOMPANY 1997 FORM 5500
                     ANNUAL REPORT OF EMPLOYEE BENEFIT PLAN
                              UNDER ERISA OF 1974

                      FOR THE YEAR ENDED DECEMBER 31, 1997


          The supplemental schedules required to accompany the Plan's Form 5500
are not required since the Plan's assets are held in a Master Trust.
Accordingly, detailed financial information, including the supplemental
schedules, must be filed separately with the Department of Labor by the plan
administrator.


                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of
Raytheon Company:

          We have audited the accompanying statements of net assets available
for plan benefits of the Raytheon Savings and Investment Plan (the "Plan") as of
December 31, 1997 and 1996, and the related statement of changes in net assets
available for plan benefits for the year ended December 31, 1997. These
financial statements are the responsibility of the Plan's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

          We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

          In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for plan benefits of
the Plan as of December 31, 1997 and 1996, and the changes in net assets
available for plan benefits for the year ended December 31, 1997 in conformity
with generally accepted accounting principles.

A.      Description of Plan:

General

          The following description of the Raytheon Savings and Investment Plan
(the "Plan") provides only general information. Participants should refer to the
plan document for a complete description of the Plan's provisions. The Plan is a
defined contribution plan covering certain employees of Raytheon Company (the
"Company"). To participate in the Plan, eligible employees must have three
months of service and may enter the Plan only on the first day of each month.
The purpose of the Plan is to provide participants with a tax-effective means of
meeting both short- and long-term investment objectives. The Plan is intended to
be a "qualified cash or deferred arrangement" under Sections 401(a) and 401(k)
of the Internal Revenue Code (the "Code"). The Plan is subject to the provisions
of the Employee Retirement Income Security Act of 1974 (ERISA).

          The Plan's investments are held in the Raytheon Company Master Trust
for Defined Contribution Plans ("Master Trust") with the assets of other defined
contribution plans of the Company and subsidiaries. The trustee of the Master
Trust maintains a separate account reflecting the equitable share in the Trust
of each plan.

          Investment income and administrative expenses relating to the Master
Trust are allocated to the individual plans based upon average monthly balances
invested by each plan.

Contributions and Deferrals

          Eligible employees are allowed to defer to the Plan up to 17% of their
salaries. The Company contributes amounts equal to 50% of each participant's
deferral, up to a maximum of 3% of the participant's salary. As of December 31,
1997, the annual employee deferral for a participant cannot exceed $9,500.
Rollover contributions from other qualified plans are accepted by the Plan.
Participants may invest their deferrals in increments of 1% in any combination
of seven funds: (a) a Fixed Income Fund under which assets are invested
primarily in contracts providing for fixed rates of interest for specified
periods of time, (b) an Equity Fund which invests in shares of a mutual fund
which consists primarily of income-producing equity securities, (c) a Raytheon
Common Stock Fund which invests in shares of Raytheon Company Class B common
stock, (d) a Stock Index Fund which invests in a commingled pool consisting
primarily of equity securities and is designed to track the S&P 500 Index, (e) a
Balanced Fund which invests in shares of a mutual fund which consists primarily
of equity securities, bonds and money market instruments, (f) the Magellan Fund,
a growth fund which invests primarily in equities of companies of all types and
sizes, and (g) the Blue Chip Fund, a growth fund which invests primarily in
equities of well known and established companies. Dividends and distributions
from investments of the Raytheon Common Stock Fund, the Equity Fund, the Stock
Index Fund, the Balanced Fund, the Magellan Fund and the Blue Chip Fund are
reinvested in their respective funds; stock dividends, stock splits and similar
changes are also reflected in the funds.

                                       5
            
Participant Accounts
               
          Each participant's account is credited with the participant's
deferral, the Company's contribution and an allocation of plan earnings. Plan
earnings are allocated based on account balances by fund.

Vesting
                
          Participants are immediately vested in their voluntary deferrals plus
actual earnings thereon. Vesting requirements for employer contributions plus
earnings thereon may vary depending upon when an employee became eligible to
participate in the Plan. Vesting generally occurs upon the earliest of the
completion of five years of service or three years of plan participation or upon
retirement, death, disability, or attainment of normal retirement age.
Forfeitures of the nonvested portions of terminated participants' accounts are
used to reduce required contributions of the Company.

Distributions to Participants
                
          A participant may withdraw all or a portion of deferrals, employer
contributions and related earnings upon attainment of age 59 1/2. For reasons of
financial hardship, as defined in the Plan document, a participant may withdraw
all or a portion of deferrals. On termination of employment, a participant will
receive a lump-sum distribution unless the vested account is valued in excess of
$3,500 and the participant elects to defer distribution. A retiree or a
beneficiary of a deceased participant may defer the distribution until January
of the year following attainment of age 65.

Loans to Participants

          A participant may borrow against a portion of the balance in the
participant's account, subject to certain restrictions. The maximum amount of a
loan is the lesser of one-half of the participant's vested account balance or
$50,000. The minimum loan which may be granted is $500. The interest rate
applied is equal to the prime rate published in the Wall Street Journal on the
first business day in June and December of each year. Loans must be repaid over
a period of up to 5 years by means of payroll deductions. In certain cases,
the repayment period may be extended up to 15 years. Interest paid to the Plan
on loans to participants is credited to the borrower's account in the investment
fund to which repayments are made.

Administrative Expenses

          Substantially all expenses of administering the Plan are paid by the

          The accompanying financial statements are prepared on the accrual
basis of accounting.
<PAGE>
                                       6

          The Plan's investment contracts are fully benefit-responsive and are
therefore included in the financial statements at their contract value, defined
as net contributions and deferrals plus interest earned on the underlying
investments at contracted rates. Because the investment contracts are fully
benefit-responsive, contract values approximate fair value. Investments in
mutual funds and the commingled pool are valued at the closing net asset value
reported on the last business day of the year. Investments in securities (common
stocks) traded on a national securities exchange are valued at the last reported
sales price on the last business day of the year. Cash equivalents are
short-term money market instruments and are valued at cost which approximates
fair value.

          Security transactions are recorded on trade date. Except for its
investment contracts (Note E), the Plan's investments are held by
bank-administered trust funds. Payables for outstanding security transactions
represent trades which have occurred but have not yet settled.

          The Plan presents in the statement of changes in net assets the net
appreciation (depreciation) in the fair value of its investments which consists
of the realized gains or losses and the unrealized appreciation (depreciation)
on those investments.

          Dividend income is recorded on the ex-dividend date. Income from other
investments is recorded as earned on an accrual basis.

          Benefits are recorded when paid.

          Certain items in the 1996 financial statements have been reclassified
to conform to the 1997 presentation.

          The preparation of the financial statements in conformity with
generally accepted accounting principles requires the plan administrator to make
significant estimates and assumptions that affect the reported amounts of net
assets and liabilities available for benefits at the date of the financial
statements and the changes in net assets available for benefits during the
reporting period and, when applicable, disclosures of contingent assets and
liabilities at the date of the financial statements. Actual results could differ
from the estimates included in the financial statements.
        
          The Plan provides for various investment options in any combination of
stocks, bonds, fixed income securities, mutual funds and other investment
securities. Investment securities are exposed to various risks, such as interest
rate, market and credit risk. Due to the level of risk associated with certain
investment securities and the level of uncertainty related to changes in the
value of investment securities, it is at least reasonably possible that changes
in risks in the near term would materially affect participants' account balances
and the amounts reported in the statement of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits.

C.      Federal Income Tax Status:

          The Plan obtained its latest determination letter in July 1995, in
which the Internal Revenue Service stated that the Plan, as submitted, was in
compliance with the applicable requirements of the Internal Revenue Code. The
Plan has been amended since receiving the determination letter. However, the
Plan administrator and the Plan's legal counsel believe that the Plan is
currently designed and being operated in compliance with the applicable
requirements of the Internal Revenue Code. Therefore, no provision for income
taxes has been included in the Plan's financial statements.

D.      Plan Termination:

          Although it has not expressed any intention to do so, the Company
reserves the right under the Plan at any time or times to discontinue its
contributions and to terminate the Plan subject to the provisions of ERISA. In
the event of Plan termination, after payment of all expenses and proportional
adjustment of accounts to reflect such expenses, fund losses or profits and
reallocations, each participant shall be entitled to receive any amounts then
credited to his or her account.

E.      Investment Contracts:

          The Plan invests in collateralized fixed income investment portfolios
(with no expiration date), three of which are managed by insurance companies and
one of which is managed by an investment management firm. The credited interest
rates are adjusted semiannually to reflect the experienced and anticipated
yields to be earned on such investments, based on their book value. The
annualized average yield and credited interest rates were as follows:

                                                       Annualized
                                                         Average    Credited
                                                          Yield   Interest Rate

For the year ended December 31, 1996:

  Prudential Asset Management Company (GIC 917163-001)    6.89%      6.99%
                                                                     

          The contract values are subject to limitations in certain situations
including large workforce reductions and plan termination. 

          In the financial statements, the two Metropolitan Life Insurance
Company contracts are recorded as one investment option.

F.      Related Party Transactions: 

          In accordance with the provisions of the Plan, Fidelity Management
Trust Company (the "Trustee") acts as the Plan's agent for purchases and sales
of shares of Raytheon Company Class B common stock. These transactions are
performed on the Master Trust level. For the Master Trust, purchases amounted to
$200,689,057 and $158,515,882 and sales amounted to $102,165,608 and $38,523,792
for the years ended December 31, 1997 and 1996, respectively.

G.      Transfers:

          Transfers include transfers of participant accounts, individually
and/or in groups, between the Raytheon Savings and Investment Plan and all other
plans included in the Raytheon Company Master Trust for those participants
and/or groups of participants who changed plans during the year. Transfers also
include transfers of participant accounts, individually and/or in groups,
between the Raytheon Savings and Investment Plan and similar savings plans of

          The supplemental schedules required to accompany the Plan's Form 5500
are not required since the Plan's assets are held in a Master Trust.
Accordingly, detailed financial information, including the supplemental
schedules, must be filed separately with the Department of Labor by the plan
administrator.


                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of
Raytheon Company:

          We have audited the accompanying statements of net assets available
for plan benefits of the Raytheon Savings and Investment Plan for Specified
Hourly Payroll Employees (the "Plan") as of December 31, 1997 and 1996, and the
related statement of changes in net assets available for plan benefits for the
year ended December 31, 1997. These financial statements are the responsibility
of the Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

          We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

          In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for plan benefits of
the Plan as of December 31, 1997 and 1996, and the changes in net assets
available for plan benefits for the year ended December 31, 1997 in conformity
with generally accepted accounting principles.

A.      Description of Plan:
                
General

          The following description of the Raytheon Savings and Investment Plan
for Specified Hourly Payroll Employees (the "Plan") provides only general
information. Participants should refer to the plan document for a complete
description of the Plan's provisions. The Plan is a defined contribution plan
covering certain hourly payroll employees of Raytheon Company (the "Company")
who are employed in units represented by specified labor unions. To participate
in the Plan, eligible employees must have three months of service and may enter
the Plan only on the first day of each month. The purpose of the Plan is to
provide participants with a tax-effective means of meeting both short- and
long-term investment objectives. The Plan is intended to be a "qualified cash or
deferred arrangement" under Sections 401(a) and 401(k) of the Internal Revenue
Code (the "Code"). The Plan is subject to the provisions of the Employee
Retirement Income Security Act of 1974 (ERISA).

          The Plan's investments are held in the Raytheon Company Master Trust
for Defined Contribution Plans "Master Trust" with the assets of other defined
contribution plans of Raytheon Company and subsidiaries. The trustee of the
Master Trust maintains a separate account reflecting the equitable share in the
Trust of each plan.

          Investment income and administrative expenses relating to the Master
Trust are allocated to the individual plans based upon average monthly balances
invested by each plan.

Contributions and Deferrals

          Eligible employees are allowed to defer to the Plan up to 17% of their
salaries. The Company contributes amounts equal to 50% of each participant's
deferral, up to a maximum of 3% of the participant's salary. As of December 31,
1997, the annual employee deferral for a participant cannot exceed $9,500.
Rollover contributions from other qualified plans are accepted by the Plan.
Participants may invest their deferrals in increments of 1% in any combination
of seven funds: (a) a Fixed Income Fund under which assets are invested
primarily in contracts providing for fixed rates of interest for specified
periods of time, (b) an Equity Fund which invests in shares of a mutual fund
which consists primarily of income-producing equity securities, (c) a Raytheon
Common Stock Fund which invests in shares of Raytheon Company Class B common
stock, (d) a Stock Index Fund which invests in a commingled pool consisting
primarily of equity securities and is designed to track the S&P 500 Index, (e) a
Balanced Fund which invests in shares of a mutual fund which consists primarily
of equity securities, bonds and money market instruments, (f) the Magellan Fund,
a growth fund which invests primarily in equities of companies of all types and
sizes, and (g) the Blue Chip Fund, a growth fund which invests primarily in
equities of well known and established companies. Dividends and distributions
from investments of the Equity Fund, the Raytheon Common Stock Fund, the Stock
Index Fund, the Balanced Fund, the Magellan Fund and the Blue Chip Fund are
reinvested in their respective funds; stock dividends, stock splits and similar
changes are also reflected in the funds.
<PAGE>
                                       5
             
Participant Accounts

          Each participant's account is credited with the participant's
deferral, the Company's contribution and an allocation of plan earnings. Plan
earnings are allocated based on account balances by fund.
                
Vesting

          Participants are immediately vested in their voluntary deferrals plus
actual earnings thereon. Vesting requirements for employer contributions plus
earnings thereon may vary depending upon when an employee became eligible to
participate in the Plan. Vesting generally occurs upon the earliest of the
completion of five years of service or upon three years of participation or upon
retirement, death, disability, or attainment of normal retirement age.
Forfeitures of the nonvested portions of terminated participants' accounts are
used to reduce required contributions of the Company.
             
Distributions to Participants
                
          A participant may withdraw all or a portion of deferrals, employer
contributions and related earnings upon attainment of age 59-1/2. For reasons of
financial hardship, as defined in the Plan document, a participant may withdraw
all or a portion of deferrals. On termination of employment, a participant will
receive a lump-sum distribution unless the vested account is valued in excess of
$3,500 and the participant elects to defer distribution. A retiree or a
beneficiary of a deceased participant may defer the distribution until January
of the year following attainment of age 65.
                
Loans to Participants
               
          A participant may borrow against a portion of the balance in the
participant's account, subject to certain restrictions. The maximum amount of a
loan is the lesser of one-half of the participant's vested account balance or
$50,000. The minimum loan which may be granted is $500. The interest rate
applied is equal to the prime rate published in the Wall Street Journal on the
first business day in June and December of each year. Loans must be repaid over
a period of up to 5 years by means payroll deductions. In certain cases, the
repayment period may be extended up to 15 years. Interest paid to the Plan on
loans to participants is credited to the borrower's account in the investment
fund to which repayments are made.
               
Administrative Expenses
                
          Substantially all expenses of administering the Plan are paid by the
plan participants.


B.      Summary of Significant Accounting Policies:

          The accompanying financial statements are prepared on the accrual
basis of accounting.
<PAGE>
                                       6

          The Plan's investment contracts are fully benefit-responsive and are
therefore included in the financial statements at their contract value, defined
as net contributions and deferrals plus interest earned on the underlying
investments at contracted rates. Because the investment contracts are fully
benefit-responsive, contract values approximate fair value. Investments in
mutual funds and the commingled pool are valued at the closing net asset value
reported on the last business day of the year. Investments in securities (common
stocks) traded on a national securities exchange are valued at the last reported
sales price on the last business day of the year. Cash equivalents are
short-term money market instruments and are valued at cost which approximates
fair value.

          Security transactions are recorded on trade date. Except for its
investment contracts (Note E), the Plan's investments are held by
bank-administered trust funds. Payables for outstanding security transactions
represent trades which have occurred but have not yet settled. 

          The Plan presents in the statement of changes in net assets the net
appreciation (depreciation) in the fair value of its investments which consists
of the realized gains or losses and the unrealized appreciation (depreciation)
on those investments.

          Dividend income is recorded on the ex-dividend date. Income from other
investments is recorded as earned on an accrual basis.

          Benefits are recorded when paid.

          Certain items in the 1996 financial statements have been reclassified
to conform to the 1997 presentation.

          The preparation of the financial statements in conformity with
generally accepted accounting principles requires the Plan administrator to make
significant estimates and assumptions that affect the reported amounts of net
assets and liabilities available for benefits at the date of the financial
statements and the changes in net assets available for benefits during the
reporting period and, when applicable, disclosures of contingent assets and
liabilities at the date of the financial statements. Actual results could differ
from the estimates included in the financial statements.

          The Plan provides for various investment options in any combination of
stocks, bonds, fixed income securities, mutual funds and other investment
securities. Investment securities are exposed to various risks, such as interest
rate, market and credit risk. Due to the level of risk associated with certain
investment securities and the level of uncertainty related to changes in the
value of investment securities, it is at least reasonably possible that changes
in risks in the near term would materially affect participants' account balances
and the amounts reported in the statement of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits.

C.      Federal Income Tax Status:

          The Plan obtained its latest determination letter in June 1995, in
which the Internal Revenue Service stated that the Plan, as submitted, was in
compliance with the applicable requirements of the Internal Revenue Code. The
Plan has been amended since receiving the determination letter. However, the
Plan administrator and the Plan's legal counsel believe that the Plan is
currently designed and being operated in compliance with the applicable
requirements of the Internal Revenue Code. Therefore, no provision for income
taxes has been included in the Plan's financial statements.

D.      Plan Termination:

          Although it has not expressed any intention to do so, the Company
reserves the right under the Plan at any time or times to discontinue its
contributions and to terminate the Plan subject to the provisions of ERISA. In
the event of plan termination, after payment of all expenses and proportional
adjustment of accounts to reflect such expenses, fund losses or profits, and
reallocations, each participant shall be entitled to receive any amounts then
credited to his or her account.

E.      Investment Contracts:

          The Plan invests in collateralized fixed income investment portfolios
(with no expiration date), three of which are managed by insurance companies and
one of which is managed by an investment management firm. The credited interest
rates are adjusted semiannually to reflect the experienced and anticipated
yields to be earned on such investments, based on their book value. The
annualized average yield and credited interest rates were as follows:
                                                        
                                                       Annualized
                                                         Average    Credited
                                                         Yield    Interest Rate

           ANNUAL REPORT OF EMPLOYEE BENEFIT PLAN UNDER ERISA OF 1974

                      FOR THE YEAR ENDED DECEMBER 31, 1997

          The supplemental schedules required to accompany the Plan's Form 5500
are not required since the Plan's assets are held in a Master Trust.
Accordingly, detailed financial information, including the supplemental
schedules, must be filed separately with the Department of Labor by the plan
administrator.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of
Raytheon Company:

          We have audited the accompanying statements of net assets available
for plan benefits of the Raytheon Employee Savings and Investment Plan (the
"Plan") as of December 31, 1997 and 1996, and the related statement of changes
in net assets available for plan benefits for the year ended December 31, 1997.
These financial statements are the responsibility of the Plan's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

          We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

          In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for plan benefits of
the Plan as of December 31, 1997 and 1996, and the changes in net assets
available for plan benefits for the year ended December 31, 1997 in conformity
with generally accepted accounting principles.

A.      Description of Plan:
              
General

          The following description of the Raytheon Employee Savings and
Investment Plan (the "Plan"), provides only general information. Participants
should refer to the plan document for a complete description of the Plan's
provisions. The Plan is a defined contribution plan and covers the employees of
the Raytheon Support Services Company, the Raytheon Aerospace Support Service
Company, and the Range Systems Engineer Support Company, wholly-owned
subsidiaries of Raytheon Company (the "Company"). To participate in the Plan,
eligible employees must have three months of service and may enter the Plan only
on the first day of each month. The purpose of the Plan is to provide
participants with a tax-effective means of meeting both short- and long-term
investment objectives. The Plan is intended to be a "qualified cash or deferred
arrangement" under Sections 401(a) and 401(k) of the Internal Revenue Code (the
"Code"). The Plan is subject to the provisions of the Employee Retirement Income
Security Act of 1974 (ERISA).

          The Plan's investments are held in the Raytheon Company Master Trust
for Defined Contribution Plans ("Master Trust") with the assets of other defined
contribution plans of Raytheon Company and subsidiaries. The trustee of the
Master Trust maintains a separate account reflecting the equitable share in the
Trust of each plan.

          Investment income and administrative expenses relating to the Master
Trust are allocated to the individual plan based upon average monthly balances
invested by each plan.

Contributions and Deferrals

          Eligible employees are allowed to defer to the Plan up to 17% of their
salaries. In 1995, the Company began to make qualified nonelective contributions
(QNECs) to certain accounts based on specific employee agreements. In 1996,
matching contributions under a specific agreement were made for certain
employees. As of December 31, 1997, the annual employee deferral for a
participant cannot exceed $9,500. Rollover contributions from other qualified
plans are accepted by the Plan. Participants may invest their deferrals in
increments of 1% in any combination of seven funds: (a) a Fixed Income Fund
under which assets are invested primarily in contracts providing for fixed rates
of interest for specified periods of time, (b) an Equity Fund which invests in
shares of a mutual fund which consists primarily of income-producing equity
securities, (c) a Raytheon Common Stock Fund which invests in shares of Raytheon
Company Class B common stock, (d) a Stock Index Fund which invests in a
commingled pool consisting primarily of equity securities and is designed to
track the S&P 500 Index, (e) a Balanced Fund which invests in shares of a mutual
fund which consists primarily of equity securities, bonds and money market
instruments, (f) the Magellan Fund, a growth fund which invests primarily in
equities of companies of all types and sizes, and (g) the Blue Chip Fund, a
growth fund which invests primarily in equities of well known and established
companies. Dividends and distributions from investments of the Equity Fund, the
Raytheon Common Stock Fund, the Stock Index Fund, the Balanced Fund, the
Magellan Fund and the Blue Chip Fund are reinvested in their respective funds;
stock dividends, stock splits and similar changes are also reflected in the
funds. <PAGE>
                                       5
            
Participant Accounts
                
          Each participant's account is credited with the participant's
deferral, any applicable employer contributions (QNECs or matching
contributions) and an allocation of plan earnings. Plan earnings are allocated
based on account balances by fund.

Vesting

          Participants are immediately vested in their voluntary deferrals and
employer contributions plus actual earnings thereon.
               
Distributions to Participants

          A participant may withdraw all or a portion of deferrals, employer
contributions and related earnings upon attainment of age 59 1/2. For reasons of
financial hardship, as defined in the Plan document, a participant may withdraw
all or a portion of deferrals. On termination of employment, a participant will
receive a lump-sum distribution unless the vested account is valued in excess of
$3,500 and the participant elects to defer distribution. A retiree or a
beneficiary of a deceased participant may defer the distribution until January
of the year following attainment of age 65.

Loans to Participants

          A participant may borrow against a portion of the balance in the
participant's account, subject to certain restrictions. The maximum amount of a
loan is the lesser of one-half of the participant's account balance or $50,000.
The minimum loan which may be granted is $500. The interest rate applied is
equal to the prime rate published in the Wall Street Journal on the first
business day in June and December of each year. Loans must be repaid over a
period of up to 5 years by means of payroll deductions. In certain cases, the
repayment period may be extended up to 15 years. Interest paid to the Plan on
loans to participants is credited to the borrower's account in the investment
fund to which repayments are made.

Administrative Expenses

          Substantially all expenses of administering the Plan are paid by the
plan participants.


B.      Summary of Significant Accounting Policies:

          The accompanying financial statements are prepared on the accrual
basis of accounting.

          The Plan's investment contracts are fully benefit-responsive and are
therefore included in the financial statements at their contract value, defined
as net employee contributions plus interest earned on the underlying investments
at contracted rates. Because the investment contracts are fully
benefit-responsive, contract values approximate fair value. Investments in
mutual funds and the commingled pool are valued at the closing net asset value
reported on the last business day of the year. Investments in securities (common
stocks) traded on a national securities exchange are valued at the last reported
sales price on the last business day of the year. Cash equivalents are
short-term money market instruments and are valued at cost which approximates
fair value.
<PAGE>
                                       6

          Security transactions are recorded on trade date. Except for its
investment contracts (Note E), the Plan's investments are held by
bank-administered trust funds. Payables for outstanding security transactions
represent trades which have occurred but have not yet settled.

          The Plan presents in the statement of changes in net assets the net
appreciation (depreciation) in the fair value of its investments which consists
of the realized gains or losses and the unrealized appreciation (depreciation)
on those investments.

          Dividend income is recorded on the ex-dividend date. Income from other
investments is recorded as earned on an accrual basis.

          Benefits are recorded when paid.

          Certain items in the 1996 financial statements have been reclassified
to conform to the 1997 presentation.

          The preparation of the financial statements in conformity with
generally accepted accounting principles requires the Plan administrator to make
significant estimates and assumptions that affect the reported amounts of net
assets and liabilities available for benefits at the date of the financial
statements and the changes in net assets available for benefits during the
reporting period and, when applicable, disclosures of contingent assets and
liabilities at the date of the financial statements. Actual results could differ
from the estimates included in the financial statements.

          The Plan provides for various investment options in any combination of
stocks, bonds, fixed income securities, mutual funds and other investment
securities. Investment securities are exposed to various risks, such as interest
rate, market and credit risk. Due to the level of risk associated with certain
investment securities and the level of uncertainty related to changes in the
value of investment securities, it is at least reasonably possible that changes
in risks in the near term would materially affect participants' account balances
and the amounts reported in the statement of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits.

C.      Federal Income Tax Status:

          The Plan obtained its latest determination letter in June 1995, in
which the Internal Revenue Service stated that the Plan, as submitted, was in
compliance with the applicable requirements of the Internal Revenue Code. The
Plan has been amended since receiving the determination letter. However, the
Plan administrator and the Plan's legal counsel believe that the Plan is
currently designed and being operated in compliance with the applicable
requirements of the Internal Revenue Code. Therefore, no provision for income
taxes has been included in the Plan's financial statements.

D.      Plan Termination:

          Although it has not expressed any intention to do so, the Company
reserves the right under the Plan at any time or times to discontinue its
contributions and to terminate the Plan subject to the provisions of ERISA. In
the event of plan termination, after payment of all expenses and proportional
adjustment of accounts to reflect such expenses, fund losses or profits, and
reallocations, each participant shall be entitled to receive any amounts then
credited to his or her account.

E.      Investment Contracts:

          The Plan invests in collateralized fixed income investment portfolios
(with no expiration date), three of which are managed by insurance companies and
one of which is managed by an investment management firm. The credited interest
rates are adjusted semiannually to reflect the experienced and anticipated
yields to be earned on such investments, based on their book value. The 
annualized average yield and credited interest rates were as follows:
 
                                                       Annualized
                                                         Average    Credited
                                                          Yield   Interest Rate

  Prudential Asset Management Company (GIC 917163-001)    6.89%       6.99%

          The contract values are subject to limitations in certain situations
including large workforce reductions and plan termination.

          In the financial statements, the two Metropolitan Life Insurance
Company contracts are recorded as one investment option.

F.      Related Party Transactions:

          In accordance with the provisions of the Plan, Fidelity Management
Trust Co. (the "Trustee") acts as the Plan's agent for purchases and sales of
shares of Raytheon Company Class B common stock. These transactions are
performed on the Master Trust level, For the Master Trust, purchases amounted to
$200,689,057 and $158,515,882 and sales amounted to $102,165,608 and $38,523,792
for the years ended December 31, 1997 and 1996, respectively.

G.      Transfers:

          Transfers include transfers of participant accounts, individually
and/or in groups, between the Plan and all other plans included in the Raytheon
Company Master Trust for those participants and/or groups of participants who
changed plans during the year. Transfers also include transfers of participant
accounts, individually and/or in groups, between the Plan and similar savings
plans of other companies for those participants who changed companies during the
year.

                     ANNUAL REPORT OF EMPLOYEE BENEFIT PLAN
                               UNDER ERISA OF 1974

          The supplemental schedules required to accompany the Plan's Form 5500
are not required since the Plan's assets are held in a Master Trust.
Accordingly, detailed financial information, including the supplemental
schedules, must be filed separately with the Department of Labor by the plan
administrator.




                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of
Raytheon Catalytic, Inc.:

          We have audited the accompanying statements of net assets available
for plan benefits of the Raytheon Savings and Investment Plan for Puerto Rico
Based Employees (the "Plan") as of December 31, 1997 and 1996, and the related
statement of changes in net assets available for plan benefits for the year
ended December 31, 1997. These financial statements are the responsibility of
the Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

          We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

          In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for plan benefits of
the Plan as of December 31, 1997 and 1996, and the changes in net assets
available for plan benefits for the year ended December 31, 1997 in conformity
with generally accepted accounting principles.

A.      Description of Plan:

                General

          The following description of the Raytheon Savings and Investment Plan
for Puerto Rico Based Employees (the "Plan") provides only general information.
Participants should refer to the plan document for a complete description of the
Plan's provisions. The Plan is a defined contribution plan covering certain
Puerto Rico based employees of Raytheon Catalytic, Inc., a wholly-owned
subsidiary of Raytheon Company (the "Company"). To participate in the Plan,
eligible employees must have three months of service and may enter the Plan only
on the first pay date of each month. The purpose of the Plan is to provide
participants with a tax-effective means of meeting both short- and long-term
investment objectives. The Plan, effective as of January 1, 1995, is intended to
comply with all the requirements for a "qualified profit sharing plan" under the
Revenue Code of Puerto Rico (the "Code"). The Plan is subject to the provisions
of the Employee Retirement Income Security Act of 1974 (ERISA).

          All of the Plan's investments are held in the Raytheon Company Master
Trust for Defined Contribution Plans ("Master Trust") with the assets of other
defined contribution plans of Raytheon Company and subsidiaries. The trustee of
the Master Trust maintains a separate account reflecting the equitable share in
the Trust of each plan.

          Investment income and administrative expenses relating to the Master
Trust are allocated to the individual plans based upon average monthly balances
invested by each plan.

Contributions and Deferrals

          Eligible employees are allowed to defer to the Plan up to 15% of their
salaries. The Company contributes amounts equal to 50% of each participant's
deferral, up to a maximum of 3% of the participant's salary. As of December 31,
1997, the annual employee deferral for a participant cannot exceed $7,000.
Rollover contributions from other qualified plans subject to the Code are
accepted by the Plan. Participants may invest their deferrals in increments of
1% in any combination of seven funds: (a) a Fixed Income Fund under which assets
are invested primarily in contracts providing for fixed rates of interest for
specified periods of time, (b) an Equity Fund which invests in shares of a
mutual fund which consists primarily of income-producing equity securities, (c)
a Raytheon Common Stock Fund which invests in shares of Raytheon Company Class B
common stock, (d) a Stock Index Fund which invests in a commingled pool
consisting primarily of equity securities and is designed to track the S&P 500
Index, (e) a Balanced Fund which invests in shares of a mutual fund which
consists primarily of equity securities, bonds and money market instruments, (f)
the Magellan Fund, a growth fund which invests primarily in equities of
companies of all types and sizes, and (g) the Blue Chip Fund, a growth fund
which invests primarily in equities of well known and established companies.
Dividends and distributions from investments of the Equity Fund, the Raytheon
Common Stock Fund, the Stock Index Fund, the Balanced Fund, the Magellan Fund
and the Blue Chip Fund are reinvested in their respective funds; stock
dividends, stock splits and similar changes are also reflected in the funds.

 Participant Accounts

          Each participant's account is credited with the participant's
deferral, the Company's contributions and an allocation of plan earnings. Plan
earnings are allocated based on account balances by fund. 

Vesting 

          Participants are immediately vested in their voluntary deferrals plus
actual earnings thereon. Vesting requirements for employer contributions plus
earnings thereon may vary depending upon when an employee became eligible to
participate in the Plan. Vesting generally occurs upon the earliest of the
completion of five years of service or three years of plan participation or upon
retirement, death, disability, or attainment of retirement age. Forfeitures of
the nonvested portions of terminated participants' accounts are used to reduce
required contributions of the Company.

Distributions to Participants

          A participant may withdraw all or a portion of deferrals, employer
contributions and related earnings upon attainment of age 59-1/2. For reasons of
financial hardship, as defined in the Plan document, a participant may withdraw
all or a portion of deferrals. On termination of employment, a participant will
receive a lump-sum distribution unless the vested account is valued in excess of
$3,500 and the participant elects to defer distribution. A retiree or a
beneficiary of a deceased participant may defer the distribution until January
of the year following attainment of age 65.

Loans to Participants

          A participant may borrow against a portion of the balance in the
participant's account, subject to certain restrictions. The maximum amount of a
loan is one-half of the participant's account balance. The minimum loan which
may be granted is $500. The interest rate applied is equal to the prime rate
published in the Wall Street Journal on the first business day in June and
December of each year. Loans must be repaid over a period of up to five years by
means of payroll deductions. In certain cases, the repayment period may be
extended up to 15 years. Interest paid to the Plan on loans to participants is
credited to the borrower's account in the investment fund to which repayments
are made.

Administrative Expenses

          Substantially all expenses of administering the Plan are paid by the
plan participants.

 B. Summary of Significant Accounting Policies:

          The accompanying financial statements are prepared on the accrual
basis of accounting.
<PAGE>
                                       6

          The Plan's investment contracts are fully benefit-responsive and are
therefore included in the financial statements at their contract value, defined
as net contributions and deferrals plus interest earned on the underlying
investments at contracted rates. Because the investment contracts are fully
benefit-responsive, contract values approximate fair value. Investments in
mutual funds and the commingled pool are valued at the closing net asset value
reported on the last business day of the year. Investments in securities (common
stocks) traded on a national securities exchange are valued at the last reported
sales price on the last business day of the year. Cash equivalents are
short-term money market instruments and are valued at cost which approximates
fair value.

          Security transactions are recorded on trade date. Except for its
investment contracts (Note E), the Plan's investments are held by
bank-administered trust funds. Payables for outstanding security transactions
represent trades which have occurred but have not yet settled.

          The Plan presents in the statement of changes in net assets the net
appreciation (depreciation) in the fair value of its investments which consists
of the realized gains or losses and the unrealized appreciation (depreciation)
on those investments.
       
          Dividend income is recorded on the ex-dividend date. Income from other
investments is recorded as earned on an accrual basis.

          Benefits are recorded when paid.

          Certain items in the 1996 financial statements have been reclassified
to conform to the 1997 presentation.

          The preparation of the financial statements in conformity with
generally accepted accounting principles requires the plan administrator to make
significant estimates and assumptions that affect the reported amounts of net
assets and liabilities available for benefits at the date of the financial
statements and the changes in net assets available for benefits during the
reporting period and, when applicable, disclosures of contingent assets and
liabilities at the date of the financial statements. Actual results could differ
from the estimates included in the financial statements.

          The Plan provides for various investment options in any combination of
stocks, bonds, fixed income securities, mutual funds and other investment
securities. Investment securities are exposed to various risks, such as interest
rate, market and credit risk. Due to the level of risk associated with certain
investment securities and the level of uncertainty related to changes in the
value of investment securities, it is at least reasonably possible that changes
in risks in the near term would materially affect participants' account balances
and the amounts reported in the statement of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits.

C.      Tax Status:

          The Plan obtained its latest determination letter in August 1996 in
which the Treasury department of the Commonwealth of Puerto Rico stated that the
Plan, as submitted, was in compliance with the applicable requirements of the
Puerto Rico Income Tax Act of 1954, as amended. Since receiving the
determination letter, the plan has been amended. The Plan administrator and the
Plan's legal counsel believe that the Plan is designed and being operated in
compliance with the applicable requirements of the aforementioned Act.
Therefore, no provision for income taxes has been included in the Plan's
financial statements.

D.      Plan Termination:

          Although it has not expressed any intention to do so, the Company
reserves the right under the Plan at any time or times to discontinue its
contributions and to terminate the Plan subject to the provisions of ERISA. In
the event of plan termination, after payment of all expenses and proportional
adjustment of accounts to reflect such expenses, fund losses or profits, and
reallocations, each participant shall be entitled to receive any amounts then
credited to his or her account.

E.      Investment Contracts:

          The Plan invests in collateralized fixed income investment portfolios
(with no expiration date), three of which are managed by insurance companies and
one of which is managed by an investment management firm. The credited interest
rates are adjusted semiannually to reflect the experienced and anticipated
yields to be earned on such investments, based on their book value. The
annualized average yield and credited interest rates were as follows:

                                                        Annualized
                                                          Average    Credited
                                                           Yield     Interest 
                                                                      Rate

For the year ended December 31, 1996:

    Prudential Asset Management Company (GIC 917163-001)   6.89%       6.99%


          The contract values are subject to limitations in certain situations
including large workforce reductions and plan termination.

          In the financial statements, the two Metropolitan Life Insurance
Company contracts are recorded as one investment option.

F.      Related Party Transactions:

          In accordance with the provisions of the Plan, Fidelity Management
Trust Company (the "Trustee") acts as the Plan's agent for purchases and sales
of shares of Raytheon Company Class B common stock. These transactions are
performed on the Master Trust level. For the Master Trust, purchases amounted to
$200,689,057 and $158,515,882 and sales amounted to $102,165,608 and $38,523,792
for the years ended December 31, 1997 and 1996, respectively.

G.      Plan Amendment:

          In 1996, the Plan was amended to require all withdrawals from the Plan
to be in cash.

H.      Transfers:

          Transfers include transfers of participant accounts, individually
and/or in groups, between the Raytheon Savings and Investment Plan for Puerto
Rico Based Employees and all other plans included in the Raytheon Company Master
Trust for those participants and/or groups of participants who changed plans
during the year. Transfers also include transfers of participant accounts,
individually and/or in groups, between the Raytheon Saving and Investment Plan
for Puerto Rico Based Employees and similar savings plans of other companies for
those participants who changed companies during the year.

                   FINANCIAL STATEMENTS AND SUPPLEMENTAL DATA
                     WITH REPORT OF INDEPENDENT ACCOUNTANTS
                 for the years ended December 31, 1997 and 1996

Report of Independent Accountants

Employee Savings Plan Administrative Committee
E-Systems, Inc. Employee Savings Plan:

We have audited the accompanying statements of net assets available for benefits
of the  E-Systems,  Inc.  Employee  Savings Plan (the "Plan") as of December 31,
1997 and 1996, and the related statements of changes in net assets available for
benefits  for  the  years  then  ended.  These  financial   statements  are  the
responsibility  of the Plan's  management.  Our  responsibility is to express an
opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all  material  respects,  the net assets  available  for benefits of the Plan at
December  31,  1997 and 1996,  and the changes in the net assets  available  for
benefits  for the  years  then  ended  in  conformity  with  generally  accepted
accounting principles.

Our audits  were  performed  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The accompanying  supplemental  schedules
of assets held for  investment  purposes as of December 31, 1997, and reportable
transactions  for the year then ended are  presented  for  purposes of complying
with  the  Department  of  Labor's  Rules  and  Regulations  for  Reporting  and
Disclosure  under the Employee  Retirement  Income Security Act of 1974, and are
not a  required  part  of  the  basic  financial  statements.  The  supplemental
schedules have been subjected to the auditing procedures applied in our audit of
the basic  financial  statements  and, in our opinion,  are fairly stated in all
material  respects  in  relation to the basic  financial  statements  taken as a
whole.

                     E-SYSTEMS, INC. EMPLOYEE SAVINGS PLAN
                         NOTES TO FINANCIAL STATEMENTS

1.      General Description:

          The E-Systems, Inc. Employee Savings Plan (the "Plan"), is a defined
contribution plan sponsored by Raytheon E-Systems, Inc. ("E-Systems" or the
"Company"), a wholly-owned subsidiary of Raytheon Company, which became
effective January 1, 1995. Employees are immediately eligible to participate in
the Plan. The Plan provides an individual account for each participant. Amounts
disbursed to participants or transfers between funds are based solely upon
amounts contributed to each participant's account adjusted to reflect any
withdrawals and distributions, investment earnings attributable to such fund
balances and appreciation or depreciation of the market value of the fund. The
Plan is subject to the provisions of the Employee Retirement Income Security Act
of 1974 ("ERISA"). The following description of the Plan is provided for general
information purposes only. A detailed description of the Plan is contained in
the Plan document.

        Employer Contributions

          The Company matches 50% of the first 3% of employee contributions to
the Plan for the Plan year through the 401(k) Tax-Advantaged Capital
Accumulation Plan ("T-CAP") Company Matching account.

          The Plan also provides for Regular Discretionary Contributions
("E-CAP") up to 1-1/2% of the lesser of (1) base rate of pay, or (2) W-2 pay
plus elected reductions. To be eligible for this contribution, the participant
must be an active employee on December 31.

          Certain Company subsidiaries may make Optional Employer Contributions.
If employed by one of these subsidiaries on December 31, the participant
receives an allocation equal to a certain percentage, determined by the Board of
Directors, of the lesser of (1) base rate of pay, or (2) W-2 pay plus elected
reductions.

        Employee Contributions

          Participants in the Plan may contribute up to 18% of their annual base
rate of pay on a pre-tax basis. Base rate of pay excludes such items as shift
differential, quarterly wage adjustments, commissions, unused sick pay,
severance pay, allowances, awards, lump sum payments, and per diem payments. The
Internal Revenue Service ("IRS") imposed limitation on employee contributions
was $9,500 for 1997 and 1996. Internal Revenue Code ("IRC") Section 415
establishes limitations on employee and employer contributions. Any
contributions exceeding these limitations are refunded to the participants in
accordance with the Plan document.

        Vesting Rights

          Participants are immediately 100% vested in their account balances
derived from Company contributions, employee contributions and any amounts
rolled over to the Plan from another eligible plan.

        Plan Trustee

          The Plan's trustee is Vanguard Fiduciary Trust Company. The trustee
holds the funds for the Plan and is responsible for managing the Plan's
investment assets, executing all investment transactions and recording approved
transactions.

        Participant Investment Programs

          Employee contributions are invested by the trustee as directed by
participants and can be invested in any combination of the funds listed below.
Company matching contributions, and other discretionary contributions, if any,
may be invested in a different combination of funds than the pre-tax
contributions. If a separate election for the Company contributions is not made
by the participant, these contributions are then invested in the same fund or
funds selected by the participant for their pre-tax contributions.

          Participants had the option of investing their contributions in any of
the following funds:

          The Vanguard Retirement Savings Trust: investments seek the highest
level of current income consistent with safety and stability of principal by
investing primarily in contracts issued by life insurance companies, investment
contracts issued by domestic commercial banks or United States branches of
foreign banks, and other similar types of fixed-principal investments. The Trust
may also hold no more than 15% of its assets in short-term obligations, money
market funds, or federally insured deposits.

          The Vanguard/Morgan Growth Fund: investments consist primarily of
common stocks of corporations with either established growth patterns, emerging
growth potential, or cyclical growth patterns.

          The Vanguard/Windsor Fund: investments consist of a portfolio of
common stocks, the objective of which is primarily long-term growth and
secondly, current income through dividends.

          The Vanguard Money Market Reserves Prime Portfolio: investments
consist of high-quality money market instruments that mature in one year or
less.
          The Vanguard Short-Term Corporate Bond Portfolio: investments consist
of investment grade bonds with maturities from less than one to four years,
including United States Treasury and agency obligations, the objective of which
is primarily to conserve principal and secondly, to maximize current income.

          The Vanguard Index Trust 500 Portfolio: investments consist of a
portfolio of stocks designed to match the performance of Standard & Poor's 500
Corporate Stock Price Index.

          The Vanguard/Wellesley Income Fund: investments consist of about 60%
in fixed-income securities and 40% in common stocks. The Fund objective is
primarily current income through dividends, and secondly, moderate capital
growth.

          The Vanguard International Value Portfolio: investments seek maximum
long-term total return consistent with reasonable risk by investing in a
diversified group of large and medium-sized companies based outside of the
United States. Total return includes both income and capital appreciation.

                                       6

          The Raytheon Common Stock Fund: investments consist of Raytheon Class
B common stock. However, contributions may be invested in the Vanguard Money
Market Reserves Prime Portfolio until a stock purchase is made.

        Loan Provisions

          Participants may obtain loans from their account balances in any of
the Vanguard Funds and/or the Raytheon Common Stock Fund. Loans bear interest at
the prime rate, as published in the Wall Street Journal on the last day of each
calendar quarter, plus one percentage point. Such interest rate is effective for
all loans during the subsequent quarter. All loans become part of the Loan Fund.
Interest charged on loans is credited to the participant's account and is
included in interest income on the statement of changes in net assets available
for benefits.

          The maximum a participant can borrow is 50% of his/her account balance
up to a limit of $50,000. While a participant may borrow up to 50% of their
E-Systems, Inc. Employee Savings Plan account balance, loans cannot be funded
from the E-CAP, Company Matching or Optional Employer accounts. However, if the
participant had a loan outstanding within the previous 12 months, IRS rules
require that the $50,000 limit be reduced by their highest outstanding loan
balance during the 12 months before the current loan request.

        Transfer Provisions

          Participants are permitted to make unlimited transfers among
investment options, with the exception of transfers out of the Vanguard
Investment Contract Trust ("VICT"). The funds transferred out of the VICT may be
transferred into one of the equity funds at any time, but must remain in these
equity funds for a period of 90 days. After the 90-day period, the funds may be
transferred out of the equity funds and into either the Vanguard Money Market
Reserves Prime Portfolio or the Vanguard Short-Term Corporate Bond Portfolio.

          Participants may only transfer funds from the VICT into fixed income
options once a year, during January. Fixed income options include the Vanguard
Money Market Reserves Prime Portfolio and the Vanguard Short-Term Corporate Bond
Portfolio. Participants may transfer up to $500 or 25% of their balance in the
VICT, whichever is higher, into the fixed income options.

        Income Allocations

          Each investment fund's gain or losses are determined and allocated by
its fund manager every business day.

        Withdrawals

          All distributions except distributions of the Raytheon Common Stock
Fund are made in cash. Participants are eligible for distributions upon
termination, retirement, disability, or hardship (as determined by the IRS).
Distributions may be made to the participant or beneficiary as a lump sum
payment or as an insured annuity. No in-service withdrawals of the company

        Plan Termination

          Although the Company has not expressed any intention to do so, it has
the right under the Plan to discontinue its contributions at any time and to
terminate the Plan subject to the provisions of ERISA. In the event of a
termination of the Plan, all plan assets would be distributed in accordance with
the Plan.

2.      Summary of Significant Accounting Policies:

          The financial statements have been prepared on the accrual basis of
accounting.

        Use of Estimates

          The preparation of the Plan's financial statements in conformity with
generally accepted accounting principles requires the plan administrator to make
significant estimates and assumptions that affect the reported amounts of net
assets available for benefits at the date of the financial statements and the
changes in net assets available for benefits during the reporting period and,
when applicable, disclosures of contingent assets and liabilities at the date of
the financial statements. Actual results could differ from those estimates.

        Risks and Uncertainties

          The Plan provides for various investment options in any combination of
stocks, bonds, fixed income securities, mutual funds, and other investment
securities. Investment securities are exposed to various risks, such as interest
rate, market and credit risks. Due to the level of risk associated with certain
investment securities, it is at least reasonably possible that changes in the
values of investment securities will occur in the near term and that such
changes could materially affect participants' account balances and the amounts
reported in the statement of net assets available for plan benefits.

        Investments

          The valuation of the Plan's investments in all funds is based on the
market value of the assets held in the funds. The Plan's relative interest in
the funds is determined on a unit-method basis. The valuation of the Vanguard
Funds is based on the closing market price of the assets which comprise the
funds on the last business day of the Plan year. Investments in the Vanguard
Retirement Savings Trust are carried at market value (which equals original cost
plus accrued interest less any distribution). Market value approximates contract
value. The valuation of Class B common stock in the Raytheon Common Stock Fund
is based on closing market price as reported on the New York Stock Exchange on
the last business day of the Plan year. Purchases and sales of securities are
reflected on the trade-date basis. Dividend income is recognized on the
ex-dividend date.

          The Plan presents in the statement of changes in net assets the net
appreciation (depreciation) in the fair value of its investments which consists
of the realized gains or losses and the unrealized appreciation (depreciation)
on those investments.

        Administrative Expenses

        The  expenses  incurred by the Plan are paid from Plan  funds.  Expenses
incurred in  administering  the Plan are generally  allocated to the  respective
fund to which they relate.

3.      Plan Amendments:

          The Plan was amended effective January 1, 1997, to include employees
of Engineering Research Associates, Inc. Retirement Savings Plan ("ERA") and
authorized the transfer of ERA employees' accounts into the Plan. This amendment
also changed the distribution policy related to prior plan employer contribution
accounts from the ERA Plan.

5.      Income Tax Status:

          The IRS has determined and informed the Company by a letter dated
December 4, 1996 that the Plan is designed in accordance with applicable
sections of the IRC. The Plan has been amended since the date the IRS made its
tax determination; however, the Plan administrator believes the Plan is designed
and currently being operated in compliance with the applicable requirements of
the IRC.

                     ANNUAL REPORT OF EMPLOYEE BENEFIT PLAN
                               UNDER ERISA OF 1974

             FOR THE PERIOD FROM JULY 11, 1997 to DECEMBER 31, 1997


          The supplemental schedules required to accompany the Plan's Form 5500
are not required since the Plan's assets are held in a Master Trust.
Accordingly, detailed financial information, including the supplemental
schedules, must be filed separately with the Department of Labor by the plan
administrator.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of
Raytheon Company:

          We have audited the accompanying statement of net assets available for
plan benefits of the Raytheon TI Systems Savings Plan (the "Plan") as of
December 31, 1997, and the related statement of changes in net assets available
for plan benefits for the period from July 11, 1997 to December 31, 1997. These
financial statements are the responsibility of the Plan's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

          We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

          In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for plan benefits of
the Plan as of December 31, 1997 and the changes in net assets available for
plan benefits for the period from July 11, 1997 to December 31, 1997 in
conformity with generally accepted accounting principles.

A.      Description of Plan:

General

          The following description of the Raytheon TI Systems Savings Plan (the
"Plan") provides only general information. Participants should refer to the plan
document for a complete description of the Plan's provisions. The Plan, which
was established on July 11, 1997, is a defined contribution plan covering
certain employees of Raytheon Company (the "Company"). Effective July 11, 1997,
employees assumed in the acquisition of the Texas Instruments defense business
and that participated in the Texas Instruments Defense Savings Plan, became
eligible to participate in the Plan. Participants have the option to rollover
amounts accumulated in plans sponsored by Texas Instruments to the Plan. Upon
election, amounts will be rolled over into funds selected by the participant. An
employee becomes eligible to participate in the Plan on the date he or she
becomes an employee and may enter the Plan any day thereafter during his or her
employment. The purpose of the Plan is to provide participants with a
tax-effective means of meeting both short- and long-term investment objectives.
The Plan is intended to be a "qualified cash or deferred arrangement" under
Sections 401(a) and 401(k) of the Internal Revenue Code (the "Code"). The Plan
is subject to the provisions of the Employee Retirement Income Security Act of
1974 (ERISA).

          The Plan's investments are held in the Raytheon Company Master Trust
for Defined Contribution Plans ("Master Trust") with the assets of other defined
contribution plans of Raytheon Company and subsidiaries. The trustee of the
Master Trust maintains a separate account reflecting the equitable share in the
Trust of each plan.

          Investment income and administrative expenses relating to the Master
Trust are allocated to the individual plans based upon average monthly balances
invested by each plan.

Contributions and Deferrals

          Eligible employees are allowed to defer to the Plan up to 17% of their
salaries. The Company contributes amounts equal to 50% of each participant's
deferral, up to a maximum of 2% of the participant's salary. As of December 31,
1997, the annual employee deferral for a participant cannot exceed $7,000.
Rollover contributions from other qualified plans are accepted by the Plan.
Participants may invest their deferrals in any combination of nine funds: (a) a
Fixed Income Fund under which assets are invested primarily in contracts
providing for fixed rates of interest for specified periods of time, (b) an
Equity Fund which invests in shares of a mutual fund which consists primarily of
income-producing equity securities, (c) a Raytheon Common Stock Fund which
invests in shares of Raytheon Company Class B common stock, (d) a Stock Index
Fund which invests in a commingled pool consisting primarily of equity
securities and is designed to track the S&P 500 Index, (e a Balanced Fund which
invests in shares of a mutual fund which consists primarily of equity
securities, bonds and money market instruments, (f) the Magellan Fund, a growth
fund which invests primarily in equities of companies of all types and sizes,
(g) the Blue Chip Fund, a growth fund which invests primarily in equities of
well known and established companies, (h) the Templeton Foreign I Fund, a
long-term capital growth fund which invests in stocks and debt obligations of
companies and governments of any nation and (i) the Investment Grade Bond Fund
which invests primarily in U.S. government and corporate bonds including,
without limitation, index funds and mutual funds. Dividends and distributions
from investments of the Equity Fund, the Raytheon Common Stock Fund, the Stock
Index Fund, the Balanced Fund, the Magellan Fund, the Blue Chip Fund, the
Templeton Foreign I Fund and the Investment Grade Bond Fund are reinvested in
their respective funds; stock dividends, stock splits and similar changes are
also reflected in the funds.

Participant Accounts

          Each participant's account is credited with the participant's
deferral, the Company's contribution and an allocation of plan earnings. Plan
earnings are allocated based on account balances by fund.

Vesting

          Participants are immediately vested in their voluntary deferrals plus
actual earnings thereon. Vesting requirements for employer contributions plus
earnings thereon may vary depending upon when an employee became eligible to
participate in the Plan. Vesting generally occurs upon the earliest of the
completion of five years of service or three years of plan participation or upon
retirement, death, disability, or attainment of normal retirement age.
Forfeitures of the nonvested portions of terminated participants' accounts are
used to reduce required contributions of the Company.
               
Distributions to Participants

          A participant may withdraw all or a portion of deferrals, employer
contributions and related earnings upon attainment of age 59-1/2. For reasons of
financial hardship, as defined in the Plan document, a participant may withdraw
all or a portion of deferrals. On termination of employment, a participant will
receive a lump-sum distribution unless the vested account is valued in excess of
$3,500 and the participant elects to defer distribution. A retiree or a
beneficiary of a deceased participant may defer the distribution until January
of the year following attainment of age 65.
               
Loans to Participants

          A participant may borrow against a portion of the balance in the
participant's account, subject to certain restrictions. The maximum amount of a
loan is the lesser of one-half of the participant's vested account balance or
$50,000. The minimum loan which may be granted is $500. The interest rate
applied is equal to the prime rate published in the Wall Street Journal on the
first business day in June and December of each year. Loans must be repaid over
a period of up to five years by means of payroll deductions. In certain cases,
the repayment period may be extended up to 15 years. Interest paid to the Plan
on loans to participants is credited to the borrower's account in the investment
fund to which repayments are made.

Administrative Expenses

          Substantially all expenses of administering the Plan are paid by the
plan participants.

B.      Summary of Significant Accounting Policies:

          The accompanying financial statements are prepared on the accrual
basis of accounting.
<PAGE>
                                       6

          The Plan's investment contracts are fully benefit-responsive and are
therefore included in the financial statements at their contract value, defined
as net contributions and deferrals plus interest earned on the underlying
investments at contracted rates. Because the investment contracts are fully
benefit-responsive, contract values approximate fair value. Investments in
mutual funds and the commingled pool are valued at the closing net asset value
reported on the last business day of the year. Investments in securities (common
stocks) traded on a national securities exchange are valued at the last reported
sales price on the last business day of the year. Cash equivalents are
short-term money market instruments and are valued at cost which approximates
fair value.

          Security transactions are recorded on trade date. Except for its
investment contracts (Note E), the Plan's investments are held by
bank-administered trust funds. Payables for outstanding security transactions
represent trades which have occurred but have not yet settled. 

          The Plan presents in the statement of changes in net assets the net
appreciation (depreciation) in the fair value of its investments which consists
of the realized gains or losses and the unrealized appreciation (depreciation)
on those investments.

          Dividend income is recorded on the ex-dividend date. Income from other
investments is recorded as earned on an accrual basis.

          Benefits are recorded when paid.

          The preparation of the financial statements in conformity with
generally accepted accounting principles requires the plan administrator to make
significant estimates and assumptions that affect the reported amounts of net
assets and liabilities available for benefits at the date of the financial
statements and the changes in net assets available for benefits during the
reporting period and, when applicable, disclosures of contingent assets and
liabilities at the date of the financial statements. Actual results could differ
from the estimates included in the financial statements.

          The Plan provides for various investment options in any combination of
stocks, bonds, fixed income securities, mutual funds and other investment
securities. Investment securities are exposed to various risks, such as interest
rate, market and credit risk. Due to the level of risk associated with certain
investment securities and the level of uncertainty related to changes in the
value of investment securities, it is at least reasonably possible that changes
in risks in the near term would materially affect participants' account balances
and the amounts reported in the statement of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits.

C.      Federal Income Tax Status:

          Given that the Plan was established effective July 11, 1997, the Plan
has not received a tax determination letter to date. Raytheon Company has
submitted an application with the Internal Revenue Service under the 401(b)
regulation of the Internal Revenue Code and expects to receive the determination
letter by December 31, 1998. The plan administrator and the Plan's legal counsel
believe that the Plan is currently designed and being operated in compliance
with the applicable requirements of the Internal Revenue Code. Therefore, no
provision for income taxes has been included in the Plan's financial statements.

D. Plan Termination:

          Although it has not expressed any intention to do so, the Company
reserves the right under the Plan at any time or times to discontinue its
contributions and to terminate the Plan subject to the provisions of ERISA. In
the event of Plan termination, plan assets shall be distributed among all
participants in proportion to their interest and employee contributions shall be
distributed in accordance with the provisions contained in section 401(k)(10) of
the Internal Revenue Code.

E.      Investment Contracts:

          The Plan invests in collateralized fixed income investment portfolios
(with no expiration date), three of which are managed by insurance companies and
one of which is managed by an investment management firm. The credited interest
rates are adjusted semiannually to reflect the experienced and anticipated
yields to be earned on such investments, based on their book value. The
annualized average yield and credited interest rates were as follows:

                                                   
                                                     Annualized      Credited
                                                   Average Yield   Interest Rate

For the year ended December 31, 1997:
   Bankers Trust (WBS 92-485)                            6.95%      6.95%
   Metropolitan Life Insurance Company (GIC GA-12908)    6.86%      6.86%
   Metropolitan Life Insurance Company (GIC GA-13659)    6.43%      6.43%
   Prudential Asset Management Company (GIC 917163-001)  6.99%      6.99%
                                                                    
          The contract values are subject to limitations in certain situations
including large workforce reductions and plan termination. 

          In the financial statements, the two Metropolitan Life Insurance
Company contracts are recorded as one investment option.

F.      Related Party Transactions:

          In accordance with the provisions of the Plan, Fidelity Management
Trust Company (the "Trustee") acts as the Plan's agent for purchases and sales
of shares of Raytheon Company Class B common stock. These transactions are
performed on the Master Trust level. For the Master Trust, purchases amounted to
$200,689,057 and sales amounted to $102,165,608 for the year ended December 31,
1997.

G.      Transfers:

          Transfers include transfers of participant accounts, individually
and/or in groups, between the Raytheon TI Systems Savings Plan and other plans
included in the Raytheon Company Master Trust for those participants, and/or
groups of participants, who changed plans during the year. Transfers also
include transfers of participant accounts, individually and/or in groups,
between the Raytheon TI Systems Savings Plan and similar savings plans of other
companies for those participants who changed companies during the year.

          During the Plan year, the participants in the Texas Instruments
Defense Savings Plan voluntarily elected to transfer approximately $149 million
into the Plan. As of December 31, 1997, there are remaining participants that
have the option to make a rollover election in a future period.

                              FINANCIAL STATEMENTS
                          TO ACCOMPANY 1997 FORM 5500
                     ANNUAL REPORT OF EMPLOYEE BENEFIT PLAN
                              UNDER ERISA OF 1974

           FOR THE PERIOD FROM DECEMBER 17, 1997 TO DECEMBER 31, 1997


          The supplemental schedules required to accompany the Plan's Form 5500
are not required since the Plan's assets are held in a Master Trust.
Accordingly, detailed financial information, including the supplemental
schedules, must be filed separately with the Department of Labor by the plan
administrator.


                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of
Raytheon Company:

          We have audited the accompanying statement of net assets available for
plan benefits of the Raytheon Salaried Savings and Investment Plan (the "Plan")
as of December 31, 1997, and the related statement of changes in net assets
available for plan benefits for the period from December 17, 1997 to December
31, 1997. These financial statements are the responsibility of the Plan's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.

          We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

          In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for plan benefits of
the Plan as of December 31, 1997, and the changes in net assets available for
plan benefits for the period from December 17, 1997 to December 31, 1997 in
conformity with generally accepted accounting principles.

A.      Description of Plan:

General

          The following description of the Raytheon Salaried Savings and
Investment Plan (the "Plan") provides only general information. Participants
should refer to the plan document for a complete description of the Plan's
provisions. The Plan, which was established on December 17, 1997, is a defined
contribution plan covering certain employees of Raytheon Company (the
"Company"). Effective December 17, 1997, employees assumed in connection with
the merger of the defense business of Hughes Electronics Corporation with the
Company, that participated in the Hughes Salaried Employees' Thrift and
Savings Plan, became eligible to participate in the Plan. Participants have the
option to rollover amounts accumulated in plans sponsored by the defense
business of Hughes Electronics Corporation to the plan. The option to make a
rollover election will extend until December 1, 1998. Upon election, amounts
will be rolled over into funds selected by the participant. As of December 31,
1997, no rollovers had been made; however, the ultimate amount to be transferred
under this option cannot be estimated at this time. To participate in the Plan,
eligible employees must have three months of service and may enter the Plan only
on the first day of each month. The purpose of the Plan is to provide
participants with a tax-effective means of meeting both short- and long-term
investment objectives. The Plan is intended to be a "qualified cash or deferred
arrangement" under Sections 401(a) and 401(k) of the Internal Revenue Code (the
"Code"). The Plan is subject to the provisions of the Employee Retirement Income
Security Act of 1974 (ERISA).

          The Plan's investments are held in the Raytheon Company Master Trust
for defined contribution plans (the "Master Trust") with the assets of other
defined contribution plans of Raytheon Company and subsidiaries. The trustee of
the Master Trust maintains a separate account reflecting the equitable share in
the Trust of each plan. 

          Investment income and administrative expenses relating to the Master
Trust are allocated to the individual plan based upon average monthly balances
invested by each plan.

Contributions and Deferrals

          Eligible employees are allowed to defer to the Plan up to 12% of their
salaries. The Company contributes amounts equal to 100% of each participant's
deferral, up to a maximum of 4% of the participant's salary. The contributions
are invested in Raytheon Company common stock for two full plan years following
the plan year for which the contributions are made, and are then allocated to
participants' accounts. As of December 31, 1997, the annual employee deferral
for a participant cannot exceed $9,500. Rollover contributions from other
qualified plans are accepted by the Plan. Participants may invest their
deferrals in increments of 1% in any combination of seven funds: (a) a Fixed
Income Fund under which assets are invested primarily in contracts providing for
fixed rates of interest for specified periods of time, (b) an Equity Fund which
invests in shares of a mutual fund which consists primarily of income-producing
equity securities, (c) a Raytheon Common Stock Fund which invests in shares of
Raytheon Company Class B common stock, (d) a Stock Index Fund which invests in a
commingled pool consisting primarily of equity securities and is designed to
track the S&P 500 Index, (e) a Balanced Fund which invests in shares of a mutual
fund which consists primarily of equity securities, bonds and money market
instruments, (f) the Magellan Fund, a growth fund which invests primarily in
equities of companies of all types and sizes, and (g) the Blue Chip Fund, a
growth fund which invests primarily in equities of well known and established
companies. Dividends and distributions from investments of the Equity Fund, the
Raytheon Common Stock Fund, the Stock Index Fund, the Balanced Fund, the
Magellan Fund and the Blue Chip Fund are reinvested in their respective funds;
stock dividends, stock splits and similar changes are also reflected in the
funds.

Participant Accounts

          Each participant's account is credited with the participant's
deferral, the Company's contribution and an allocation of plan earnings. Plan
earnings are allocated based on account balances by fund.

Vesting

          Participants are immediately vested in their voluntary deferrals plus
actual earnings thereon. Vesting requirements for employer contributions plus
earnings thereon may vary depending upon when an employee became eligible to
participate in the plan. Vesting generally occurs upon the earliest of the
completion of five years of service or three years of Plan participation, or
upon retirement, death, disability, or attainment of normal retirement age.
Forfeitures of the nonvested portions of terminated participants' accounts are
used to reduce required contributions of the Company.

Distributions to Participants

          A participant may withdraw all or a portion of deferrals, employer
contributions and related earnings upon attainment of age 59-1/2. For reasons of
financial hardship, as defined in the Plan document, a participant may withdraw
all or a portion of deferrals. On termination of employment, a participant will
receive a lump-sum distribution unless the vested account is valued in excess of
$3,500 and the participant elects to defer distribution. A retiree or a
beneficiary of a deceased participant may defer the distribution until January
of the year following attainment of age 65. There were no distributions to
participants during the year.

Loans to Participants

          A participant may borrow against a portion of the balance in the
participant's account, subject to certain restrictions. The maximum amount of a
loan is the lesser of one-half of the participant's vested account balance or
$50,000. The minimum loan which may be granted is $500. The interest rate
applied is equal to the prime rate published in the Wall Street Journal on the
first business day in June and December of each year. Loans must be repaid over
a period of up to 5 years by means of payroll deductions. In certain cases, the
repayment period may be extended up to 15 years. Interest paid to the Plan on
loans to participants is credited to the borrower's account in the investment
fund to which repayments are made.

Administrative Expenses

          Substantially all expenses of administering the Plan are paid by the
plan participants.

B.      Summary of Significant Accounting Policies:

        The accompanying  financial statements are prepared on the accrual basis
of accounting.
<PAGE>
                                       6

          The Plan's investment contracts are fully benefit-responsive and are
therefore included in the financial statements at their contract value, defined
as net contributions and deferrals plus interest earned on the underlying
investments at contracted rates. Because the investment contracts are fully
benefit-responsive, contract values approximate fair value. Investments in
mutual funds and the commingled pool are valued at the closing net asset value
reported on the last business day of the year. Investments in securities (common
stocks) traded on a national securities exchange are valued at the last reported
sales price on the last business day of the year. Cash equivalents are
short-term money market instruments and are valued at cost which approximates
fair value.

          Security transactions are recorded on trade date. Except for its
investment contracts (Note E), the Plan's investments are held by
bank-administered trust funds. Payables for outstanding security transactions
represent trades which have occurred but have not yet settled. 

          The Plan presents in the statement of changes in net assets the net
appreciation (depreciation) in the fair value of its investments which consists
of the realized gains or losses and the unrealized appreciation (depreciation)
on those investments.

          Dividend income is recorded on the ex-dividend date. Income from other
investments is recorded as earned on an accrual basis.

          Benefits are recorded when paid.

          The preparation of the financial statements in conformity with
generally accepted accounting principles requires the plan administrator to make
significant estimates and assumptions that affect the reported amounts of net
assets and liabilities available for benefits at the date of the financial
statements and the change in net assets available for benefits during the
reporting period and, when applicable, disclosures of contingent assets and
liabilities at the date of the financial statements. Actual results could differ
from the estimates included in the financial statements.

          The Plan provides for various investment options in any combination of
stocks, bonds, fixed income securities, mutual funds and other investment
securities. Investment securities are exposed to various risks, such as interest
rate, market and credit risk. Due to the level of risk associated with certain
investment securities and the level of uncertainty related to changes in the
value of investment securities, it is at least reasonably possible that changes
in risks in the near term would materially affect participants' account balances
and the amounts reported in the statement of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits.

C.      Federal Income Tax Status:

          Given that the Plan was established effective December 17, 1997, the
Plan has not received a tax determination letter to date. Raytheon Company has
submitted an application with the Internal Revenue Service under the 401(b)
regulation of the Internal Revenue Code and expects to receive the determination
letter by December 31, 1998. The Plan administrator and the Plan's legal counsel
believe that the Plan is currently designed and being operated in compliance
with the applicable requirements of the Internal Revenue Code. Therefore, no
provision for income taxes has been included in the Plan's financial statements.

D.      Plan Termination:

          Although it has not expressed any intention to do so, the Company
reserves the right under the Plan at any time or times to discontinue its
contributions and to terminate the Plan subject to the provisions of ERISA. In
the event of Plan termination, amounts in participants' accounts will be
distributed in a single lump sum; if the participant does not consent to an
immediate distribution, the amount can be transferred to another defined
contribution plan sponsored by the Company.

                                       7

E.      Investment Contracts:

          The Plan invests in collateralized fixed income investment portfolios
(with no expiration date), three of which are managed by insurance companies and
one of which is managed by an investment management firm. The credited interest
rates are adjusted semiannually to reflect the experienced and anticipated
yields to be earned on such investments, based on their book value. The 
annualized average yield and credited interest rates were as follows:

                                                         Annualized
                                                          Average    Credited
                                                           Yield   Interest Rate

For the year ended December 31, 1997:
     Bankers Trust (WBS 92-485)                            6.95%       6.95%
     Metropolitan Life Insurance Company (GIC GA-12908)    6.86%       6.86%
     Metropolitan Life Insurance Company (GIC GA-13659)    6.43%       6.43%
     Prudential Asset Management Company (GIC 917163-001)  6.99%       6.99%

          The contract values are subject to limitations in certain situations
including large workforce reductions and plan termination. 

          In the financial statements, the two Metropolitan Life Insurance
Company contracts are recorded as one investment option.

F.      Related Party Transactions:

          In accordance with the provisions of the Plan, Fidelity Management

                FINANCIAL STATEMENTS TO ACCOMPANY 1997 FORM 5500
           ANNUAL REPORT OF EMPLOYEE BENEFIT PLAN UNDER ERISA OF 1974

           FOR THE PERIOD FROM DECEMBER 17, 1997 TO DECEMBER 31, 1997

          The supplemental schedules required to accompany the Plan's Form 5500
are not required since the Plan's assets are held in a Master Trust.
Accordingly, detailed financial information, including the supplemental
schedules, must be filed separately with the Department of Labor by the plan
administrator.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of
Raytheon Company:

          We have audited the accompanying statement of net assets available for
plan benefits of the Raytheon California Hourly Savings and Investment Plan (the
"Plan") as of December 31, 1997 and the related statement of changes in net
assets available for plan benefits for the period from December 17, 1997 to
December 31, 1997. These financial statements are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audit.

          We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

          In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for plan benefits of
the Plan as of December 31, 1997, and the changes in net assets available for
plan benefits for the period from December 17, 1997 to December 31, 1997 in
conformity with generally accepted accounting principles.

A.      Description of Plan:

General

          The following description of the Raytheon California Hourly Savings
and Investment Plan (the "Plan") provides only general information. Participants
should refer to the plan document for a complete description of the Plan's
provisions. The Plan, which was established on December 17, 1997, is a defined
contribution plan covering certain employees of Raytheon Company (the
"Company"). Effective December 17, 1997, employees assumed in connection with
the merger of the defense business of Hughes Electronics Corporation with the
Company that participated in the Hughes California Hourly Employees' Thrift and
Savings Plan, became eligible to participate in the Plan. Participants have the
option to rollover amounts accumulated in plans sponsored by the defense
business of Hughes Electronics Corporation to the Plan. The option to make a
rollover election will extend until December 1, 1998. Upon election, amounts
will be rolled over into funds selected by the participant. As of December 31,
1997, no rollovers had been made; however, the ultimate amount to be transferred
under this option cannot be estimated at this time. To participate in the Plan,
eligible employees must have three months of service and may enter the Plan only
on the first day of each month. The purpose of the Plan is to provide
participants with a tax-effective means of meeting both short- and long-term
investment objectives. The Plan is intended to be a "qualified cash or deferred
arrangement" under Sections 401(a) and 401(k) of the Internal Revenue Code (the
"Code"). The Plan is subject to the provisions of the Employee Retirement Income
Security Act of 1974 (ERISA).

          The Plan's investments are held in the Raytheon Company Master Trust
for Defined Contribution Plans ("Master Trust") with the assets of other
defined contribution plans of Raytheon Company and subsidiaries. The trustee of
the Master Trust maintains a separate account reflecting the equitable share in
the Trust of each plan. 

          Investment income and administrative expenses relating to the Master
Trust are allocated to the individual plans based upon average monthly balances
invested by each plan.

                                       5

Contributions and Deferrals

          Eligible employees are allowed to defer to the Plan up to 12% of their
salaries. The Company contributes amounts equal to 100% of each participant's
deferral, up to a maximum of 4% of the participant's salary. The contributions
are invested in Raytheon Company Class B common stock for two full plan years
following the plan year for which the contributions are made, and are then
allocated to participants' accounts. As of December 31, 1997, the annual
employee deferral for a participant cannot exceed $9,500. Rollover contributions
from other qualified plans are accepted by the Plan. Participants may invest
their deferrals in increments of 1% in any combination of seven funds: (a)a
Fixed Income Fund under which assets are invested primarily in contracts
providing for fixed rates of interest for specified periods of time, (b)an
Equity Fund which invests in shares of a mutual fund which consists primarily of
income-producing equity securities, (c)a Raytheon Common Stock Fund which
invests in shares of Raytheon Company Class B common stock, (d)a Stock Index
Fund which invests in a commingled pool consisting primarily of equity
securities and is designed to track the S&P 500 Index, (e) a Balanced Fund which
invests in shares of a mutual fund which consists primarily of equity
securities, bonds and money market instruments, (f) the Magellan Fund, a growth
fund which invests primarily in equities of companies of all types and sizes,
and (g) the Blue Chip Fund, a growth fund which invests primarily in equities of
well known and established companies. Dividends and distributions from
investments of the Equity Fund, the Raytheon Common Stock Fund, the Stock Index
Fund, the Balanced Fund, the Magellan Fund and the Blue Chip Fund are reinvested
in their respective funds; stock dividends, stock splits and similar changes are
also reflected in the funds.

Participant Accounts

          Each participant's account is credited with the participant's
deferral, the Company's contribution and an allocation of plan earnings. Plan
earnings are allocated based on account balances by fund.

Vesting

          Participants are immediately vested in their voluntary deferrals plus
actual earnings thereon. Vesting requirements for employer contributions plus
earnings thereon may vary depending upon when an employee became eligible to
participate in the Plan. Vesting generally occurs upon the earliest of the
completion of five years of service or three years of Plan participation or upon
retirement, death, disability, or attainment of normal retirement age.
Forfeitures of the nonvested portions of terminated participants' accounts are
used to reduce required contributions of the Company.
           
Distributions to Participants

          A participant may withdraw all or a portion of deferrals, employer
contributions and related earnings upon attainment of age 59 1/2. For reasons of
financial hardship, as defined in the Plan document, a participant may withdraw
all or a portion of deferrals. On termination of employment, a participant will
receive a lump-sum distribution unless the vested account is valued in excess of
$3,500 and the participant elects to defer distribution. A retiree or a
beneficiary of a deceased participant may defer the distribution until January
of the year following attainment of age 65. There were no distributions to
participants during the year.

                                       6

Loans to Participants

          A participant may borrow against a portion of the balance in the
participant's account, subject to certain restrictions. The maximum amount of a
loan is the lesser of one-half of the participant's vested account balance or
$50,000. The minimum loan which may be granted is $500. The interest rate
applied is equal to the prime rate published in the Wall Street Journal on the
first business day in June and December of each year. Loans must be repaid over
a period of up to 5 years by means of payroll deductions. In certain cases, the
repayment period may be extended up to 15 years. Interest paid to the Plan on
loans to participants is credited to the borrower's account in the investment
fund to which repayments are made.

Administrative Expenses

          Substantially all expenses of administering the Plan are paid by the
plan participants.

B.        Summary of Significant Accounting Policies:

          The accompanying financial statements are prepared on the accrual
basis of accounting.

          The Plan's investment contracts are fully benefit-responsive and are
therefore included in the financial statements at their contract value, defined
as net contributions and deferrals plus interest earned on the underlying
investments at contracted rates. Because the investment contracts are fully
benefit-responsive, contract values approximate fair value. Investments in
mutual funds and the commingled pool are valued at the closing net asset value
reported on the last business day of the year. Investments in securities (common
stocks) traded on a national securities exchange are valued at the last reported
sales price on the last business day of the year. Cash equivalents are
short-term money market instruments and are valued at cost which approximates
fair value.

          Security transactions are recorded on trade date. Except for its
investment contracts (Note E), the Plan's investments are held by
bank-administered trust funds. Payables for outstanding security transactions
represent trades which have occurred but have not yet settled.

          The Plan presents in the statement of changes in net assets the net
appreciation (depreciation) in the fair value of its investments which consists
of the realized gains or losses and the unrealized appreciation (depreciation)
on those investments.

          Dividend income is recorded on the ex-dividend date. Income from other
investments is recorded as earned on an accrual basis. 

          Benefits are recorded when paid.
<PAGE>
                                       7

          The preparation of the financial statements in conformity with
generally accepted accounting principles requires the plan administrator to make
significant estimates and assumptions that affect the reported amounts of net
assets and liabilities available for benefits at the date of the financial
statements and the change in net assets available for benefits during the
reporting period and, when applicable, disclosures of contingent assets and
liabilities at the date of the financial statements. Actual results could differ
from the estimates included in the financial statements.

          The Plan provides for various investment options in any combination of
stocks, bonds, fixed income securities, mutual funds and other investment
securities. Investment securities are exposed to various risks, such as interest
rate, market and credit risk. Due to the level of risk associated with certain
investment securities and the level of uncertainty related to changes in the
value of investment securities, it is at least reasonably possible that changes
in risks in the near term would materially affect participants' account balances
and the amounts reported in the statement of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits.

C.      Federal Income Tax Status:

          Given that the Plan was established effective December 17, 1997, the
Plan has not received a tax determination letter to date. Raytheon Company has
submitted an application with the Internal Revenue Service under the 401(b)
regulation of the Internal Revenue Code and expects to receive the determination
letter by December 31, 1998. The Plan administrator and the Plan's legal counsel
believe that the Plan is currently designed and being operated in compliance
with the applicable requirements of the Internal Revenue Code. Therefore, no
provision for income taxes has been included in the Plan's financial statements.

D.      Plan Termination:

          Although it has not expressed any intention to do so, the Company
reserves the right under the Plan at any time or times to discontinue its
contributions and to terminate the Plan subject to the provisions of ERISA. In
the event of plan termination, amounts in participants' accounts will be
distributed in a single lump sum; if the participant does not consent to an
immediate distribution, the amount can be transferred to another defined
contribution plan sponsored by the Company.

E.      Investment Contracts:

          The Plan invests in collateralized fixed income investment portfolios
(with no expiration date), three of which are managed by insurance companies and
one of which is managed by an investment management firm. The credited interest
rates are adjusted semiannually to reflect the experienced and anticipated
yields to be earned on such investments, based on their book value. The 
annualized average yield and credited interest rates were as follows:

                                                          Annualized  Credited
                                                           Average    Interest 
                                                            Yield       Rate 
                                                     
For the year ended December 31, 1997:
    Bankers Trust (WBS 92-485)                              6.95%   6.95%
    Metropolitan Life Insurance Company (GIC GA-12908)      6.86%   6.86%
    Metropolitan Life Insurance Company (GIC GA-13659)      6.43%   6.43%
    Prudential Asset Management Company (GIC 917163-001)    6.99%   6.99%

          The contract values are subject to limitations in certain situations
including large workforce reductions and plan termination. 

          In the financial statements, the two Metropolitan Life Insurance
Company contracts are recorded as one investment option.

F.      Related Party Transactions:

          In accordance with the provisions of the Plan, Fidelity Management
Trust Company (the "Trustee") acts as the Plan's agent for purchases and sales
of shares of Raytheon Company Class B common stock. These transactions are
performed on the Master Trust level. For the Master Trust, purchases amounted to
$200,689,057 and sales amounted to $102,165,608 for the year ended December 31,
1997.

                              UNDER ERISA OF 1974

          The supplemental schedules required to accompany the Plan's Form 5500
are not required since the Plan's assets are held in a Master Trust.
Accordingly, detailed financial information, including the supplemental
schedules, must be filed separately with the Department of Labor by the plan
administrator.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of
Raytheon Company:

          We have audited the accompanying statement of net assets available for
plan benefits of the Raytheon Tucson Bargaining Savings and Investment Plan
("the Plan") as of December 31, 1997, and the related statement of changes in
net assets available for plan benefits for the period from December 17, 1997 to
December 31, 1997. These financial statements are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audit.

          We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

          In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for plan benefits of
the Plan as of December 31, 1997, and the changes in net assets available for
plan benefits for the period from December 17, 1997 to December 31, 1997 in
conformity with generally accepted accounting principles.

A.      Description of Plan:

General

          The following description of the Raytheon Tucson Bargaining Savings
and Investment Plan (the "Plan") provides only general information. Participants
should refer to the plan document for a complete description of the Plan's
provisions. The Plan, which was established on December 17, 1997, is a defined
contribution plan covering certain employees of Raytheon Company (the
"Company"). Effective December 17, 1997, employees assumed in connection with
the merger of the defense business of Hughes Electronics Corporation with the
Company that participated in the Hughes Tucson Bargaining Employees' Thrift and
Savings Plan, became eligible to participate in the Plan. Participants have the
option to rollover amounts accumulated in plans sponsored by the defense
business of Hughes Electronics Corporation to the Plan. The option to make a
rollover election will extend until December 1, 1998. Upon election, amounts
will be rolled over into funds selected by the participant. As of December 31,
1997, no rollovers had been made; however, the ultimate amount to be transferred
under this option cannot be estimated at this time. To participate in the Plan,
eligible employees must have three months of service and may enter the Plan only
on the first day of each month. The purpose of the Plan is to provide
participants with a tax-effective means of meeting both short- and long-term
investment objectives. The Plan is intended to be a "qualified cash or deferred
arrangement" under Sections 401(a) and 401(k) of the Internal Revenue Code (the
"Code"). The Plan is subject to the provisions of the Employee Retirement Income
Security Act of 1974 (ERISA).

          The Plan's investments are held by the Raytheon Company Master Trust
for Defined Contribution Plans ("Master Trust") with the assets of other defined
contribution plans of Raytheon Company and subsidiaries. The trustee of the
Master Trust maintains a separate account reflecting the equitable share in the
Trust of each plan.

          Investment income and administrative expenses relating to the Master
Trust are allocated to the individual plans based upon average monthly balances
invested by each plan.

Contributions and Deferrals

          Eligible employees are allowed to defer to the Plan up to 12% of their
salaries. The Company contributes amounts equal to 100% of each participant's
deferral, up to a maximum of 4% of the participant's salary. The contributions
are invested in Raytheon Company Class B common stock for two full plan years
following the plan year for which the contributions are made, and are then
allocated to participants' accounts. As of December 31, 1997, the annual
employee deferral for a participant cannot exceed $9,500. Rollover contributions
from other qualified plans are accepted by the Plan. Participants may invest
their deferrals in increments of 1% in any combination of seven funds: (a)a
Fixed Income Fund under which assets are invested primarily in contracts
providing for fixed rates of interest for specified periods of time, (b)an
Equity Fund which invests in shares of a mutual fund which consists primarily of
income-producing equity securities, (c)a Raytheon Common Stock Fund which
invests in shares of Raytheon Company Class B common stock, (d)a Stock Index
Fund which invests in a commingled pool consisting primarily of equity
securities and is designed to track the S&P 500 Index, (e) a Balanced Fund which
invests in shares of a mutual fund which consists primarily of equity
securities, bonds and money market instruments, (f) the Magellan Fund, a growth
fund which invests primarily in equities of companies of all types and sizes,
and (g) the Blue Chip Fund, a growth fund which invests primarily in equities of
well known and established companies. Dividends and distributions from
investments of the Raytheon Common Stock Fund, the Equity Fund, the Stock Index
Fund, the Balanced Fund, the Magellan Fund and the Blue Chip Fund are reinvested
in their respective funds; stock dividends, stock splits and similar changes are
also reflected in the funds.

Participant Accounts

          Each participant's account is credited with the participant's
deferral, the Company's contribution and an allocation of plan earnings. Plan
earnings are allocated based on account balances by fund.

Vesting

          Participants are immediately vested in their voluntary deferrals plus
actual earnings thereon. Vesting requirements for employer contributions plus
earnings thereon may vary depending upon when an employee became eligible to
participate in the Plan. Vesting generally occurs upon the earliest of the
completion of five years of service or three years of Plan participation or upon
retirement, death, disability, or attainment of normal retirement age.
Forfeitures of the nonvested portions of terminated participants' accounts are
used to reduce required contributions of the Company.

Distributions to Participants

          A participant may withdraw all or a portion of deferrals, employer
contributions and related earnings upon attainment of age 59-1/2. For reasons of
financial hardship, as defined in the Plan document, a participant may withdraw
all or a portion of deferrals. On termination of employment, a participant will
receive a lump-sum distribution unless the vested account is valued in excess of
$3,500 and the participant elects to defer distribution. A retiree or a
beneficiary of a deceased participant may defer the distribution until January
of the year following attainment of age 65. There were no distributions to
participants during the year.

Loans to Participants

          A participant may borrow against a portion of the balance in the
participant's account, subject to certain restrictions. The maximum amount of a
loan is the lesser of one-half of the participant's vested account balance or
$50,000. The minimum loan which may be granted is $500. The interest rate
applied is equal to the prime rate published in the Wall Street Journal on the
first business day in June and December of each year. Loans must be repaid over
a period of up to 5 years by means of payroll deductions. In certain cases, the
repayment period may be extended up to 15 years. Interest paid to the Plan on
loans to participants is credited to the borrower's account in the investment
fund to which repayments are made.

Administrative Expenses

          Substantially all expenses of administering the Plan are paid by the
plan participants.

B.      Summary of Significant Accounting Policies:

          The accompanying financial statements are prepared on the accrual
basis of accounting.

          The Plan's investment contracts are fully benefit-responsive and are
therefore included in the financial statements at their contract value, defined
as net contributions and deferrals plus interest earned on the underlying
investments at contracted rates. Because the investment contracts are fully
benefit-responsive, contract values approximate fair value. Investments in
mutual funds and the commingled pool are valued at the closing net asset value
reported on the last business day of the year. Investments in securities (common
stocks) traded on a national securities exchange are valued at the last reported
sales price on the last business day of the year. Cash equivalents are
short-term money market instruments and are valued at cost which approximates
fair value.

          Security transactions are recorded on trade date. Except for its
investment contracts (Note E), the Plan's investments are held by
bank-administered trust funds. Payables for outstanding security transactions
represent trades which have occurred but have not yet settled.

          The Plan presents in the statement of changes in net assets the net
appreciation (depreciation) in the fair value of its investments which consists
of the realized gains or losses and the unrealized appreciation (depreciation)
on those investments.

          Dividend income is recorded on the ex-dividend date. Income from other
investments is recorded as earned on an accrual basis.

          Benefits are recorded when paid.

          The preparation of the financial statements in conformity with
generally accepted accounting principles requires the plan administrator to make
significant estimates and assumptions that affect the reported amounts of net
assets and liabilities available for benefits at the date of the financial
statements and the change in net assets available for benefits during the
reporting period and, when applicable, disclosures of contingent assets and
liabilities at the date of the financial statements Actual results could differ
from the estimates included in the financial statements.

          The Plan provides for various investment options in any combination of
stocks, bonds, fixed income securities, mutual funds and other investment
securities. Investment securities are exposed to various risks, such as interest
rate, market and credit risk. Due to the level of risk associated with certain
investment securities and the level of uncertainty related to changes in the
value of investment securities, it is at least reasonably possible that changes
in risks in the near term would materially affect participants' account balances
and the amounts reported in the statement of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits.

C.      Federal Income Tax Status:

          Given that the Plan was established effective December 17, 1997, the
Plan has not received a tax determination letter to date. Raytheon Company has
submitted an application with the Internal Revenue Service under the 401(b)
regulation of the Internal Revenue Code and expects to receive the determination
letter by December 31, 1998. The Plan administrator and the Plan's legal counsel
believe that the Plan is currently designed and being operated in compliance
with the applicable requirements of the Internal Revenue Code. Therefore, no
provision for income taxes has been included in the Plan's financial statements.

D.      Plan Termination:

          Although it has not expressed any intention to do so, the Company
reserves the right under the Plan at any time or times to discontinue its
contributions and to terminate the Plan subject to the provisions of ERISA. In
the event of plan termination, amounts in participants' accounts will be
distributed in a single lump sum; if the participant does not consent to an
immediate distribution, the amount can be transferred to another defined
contribution plan sponsored by the Company.

E.      Investment Contracts:

          The Plan invests in collateralized fixed income investment portfolios
(with no expiration date), three of which are managed by insurance companies and
one of which is managed by an investment management firm. The credited interest
rates are adjusted semiannually to reflect the experienced and anticipated
yields to be earned on such investments, based on their book value. The 
annualized average yield and credited interest rates were as follows:

                                                        Annualized
                                                          Average    Credited
                                                           Yield   Interest Rate

For the year ended December 31, 1997:
   Bankers Trust (WBS 92-485)                              6.95%      6.95%
   Metropolitan Life Insurance Company (GIC GA-12908)      6.86%      6.86%
   Metropolitan Life Insurance Company (GIC GA-13659)      6.43%      6.43%
   Prudential Asset Management Company (GIC 917163-001)    6.99%      6.99%

          The contract values are subject to limitations in certain situations
including large workforce reductions and plan termination. 

          In the financial statements, the two Metropolitan Life Insurance
Company contracts are recorded as one investment option.

F.      Related Party Transactions:

          In accordance with the provisions of the Plan, Fidelity Management
Trust Company (the "Trustee") acts as the Plan's agent for purchases and sales
of shares of Raytheon Company Class B common stock. These transactions are
performed on the Master Trust Level. For the Master Trust, purchases amounted to
$200,689,057 and sales amounted to $102,165,608 for the year ended December 31,
1997.

                              FINANCIAL STATEMENTS
                          TO ACCOMPANY 1997 FORM 5500
                     ANNUAL REPORT OF EMPLOYEE BENEFIT PLAN
                              UNDER ERISA OF 1974

           FOR THE PERIOD FROM DECEMBER 17, 1997 TO DECEMBER 31, 1997


          The supplemental schedules required to accompany the Plan's Form 5500
are not required since the Plan's assets are held in a Master Trust.
Accordingly, detailed financial information, including the supplemental
schedules, must be filed separately with the Department of Labor by the plan
administrator.


                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors of
Raytheon Company:

          We have audited the accompanying statement of net assets available for
plan benefits of the Raytheon Savings and Investment Plan (10014) (the "Plan")
as of December 31, 1997, and the related statement of changes in net assets
available for plan benefits for the period from December 17, 1997 to December
31, 1997. These financial statements are the responsibility of the Plan's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.

          We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

          In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for plan benefits of
the Plan as of December 31, 1997, and the changes in net assets available for
plan benefits for the period from December 17, 1997 to December 31, 1997 in
conformity with generally accepted accounting principles.

A.      Description of Plan:

General

          The following description of the Raytheon Savings and Investment Plan
(10014)(the "Plan") provides only general information. Participants should refer
to the plan document for a complete description of the Plan's provisions. The
Plan, which was established on December 17, 1997, is a defined contribution plan
covering certain employees of Raytheon Company (the "Company"). Effective
December 17, 1997, employees assumed in connection with the merger of the
defense business of Hughes Electronics Corporation with the Company that
participated in the Hughes Thrift and Savings Plan, became eligible to
participate in the Plan. Participants have the option to rollover amounts
accumulated in plans sponsored by the defense business of Hughes Electronics
Corporation to the Plan. The option to make a rollover election will extend
until December 1, 1998. Upon election, amounts will be rolled over into funds
selected by the participant. As of December 31, 1997, no rollovers had been
made; however, the ultimate amount to be transferred under this option cannot be
estimated at this time. To participate in the Plan, eligible employees must have
three months of service and may enter the Plan only on the first day of each
month. The purpose of the Plan is to provide participants with a tax-effective
means of meeting both short- and long-term investment objectives. The Plan is
intended to be a "qualified cash or deferred arrangement" under Sections 401(a)
and 401(k) of the Internal Revenue Code (the "Code"). The Plan is subject to the
provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

          The Plan's investments are held in the Raytheon Company Master Trust
for Defined Contribution Plans ("Master Trust") with the assets of other
defined contribution plans of Raytheon Company and subsidiaries. The trustee of
the Master Trust maintains a separate account reflecting the equitable share in
the Trust of each plan. 

          Investment income and administrative expenses relating to the Master
Trust are allocated to the individual plans based upon average monthly balances
invested by each plan.

Contributions and Deferrals

          Eligible employees are allowed to defer to the Plan up to 10% of their
salaries. The Company contributes amounts equal to 50% of each participant's
deferral, up to a maximum of 3% of the participant's salary. The contributions
are invested in Raytheon Company Class B common stock for two full plan years
following the plan year for which the contributions are made, and are then
allocated to the participants' accounts. As of December 31, 1997, the annual
employee deferral for a participant cannot exceed $9,500. Rollover contributions
from other qualified plans are accepted by the Plan. Participants may invest
their deferrals in increments of 1% in any combination of seven funds: (a)a
Fixed Income Fund under which assets are invested primarily in contracts
providing for fixed rates of interest for specified periods of time, (b)an
Equity Fund which invests in shares of a mutual fund which consists primarily of
income-producing equity securities, (c) a Raytheon Common Stock Fund which
invests in shares of Raytheon Company Class B common stock, (d) a Stock Index
Fund which invests in a commingled pool consisting primarily of equity
securities and is designed to track the S&P 500 Index, (e) a Balanced Fund which
invests in shares of a mutual fund which consists primarily of equity
securities, bonds and money market instruments, (f) the Magellan Fund, a growth
fund which invests primarily in equities of companies of all types and sizes,
and (g) the Blue Chip Fund, a growth fund which invests primarily in equities of
well known and established companies. Dividends and distributions from
investments of the Equity Fund, the Raytheon Common Stock Fund, the Stock Index
Fund, the Balanced Fund, the Magellan Fund and the Blue Chip Fund are
reinvested in their respective funds; stock dividends, stock splits and
similar changes are also reflected in the funds.

                                       5

Participant Accounts

          Each participant's account is credited with the participant's
deferral, the Company's contribution and an allocation of plan earnings. Plan
earnings are allocated based on account balances by fund.
                
Vesting

          Participants are immediately vested in their voluntary deferrals plus
actual earnings thereon. Vesting requirements for employer contributions plus
earnings thereon may vary depending upon when an employee became eligible to
participate in the Plan. Vesting generally occurs upon the earliest of the
completion of five years of service or three years of Plan participation or upon
retirement, death, disability, or attainment of normal retirement age.
Forfeitures of the nonvested portions of terminated participants' accounts are
used to reduce required contributions of the Company.

Distributions to Participants

          A participant may withdraw all or a portion of deferrals, employer
contributions and related earnings upon attainment of age 59-1/2. For reasons of
financial hardship, as defined in the Plan document, a participant may withdraw
all or a portion of deferrals. On termination of employment, a participant will
receive a lump-sum distribution unless the vested account is valued in excess of
$3,500 and the participant elects to defer distribution. A retiree or a
beneficiary of a deceased participant may defer the distribution until January
of the year following attainment of age 65. There were no distributions to
participants during the year.

Loans to Participants

          A participant may borrow against a portion of the balance in the
participant's account, subject to certain restrictions. The maximum amount of a
loan is the lesser of one-half of the participant's vested account balance or
$50,000. The minimum loan which may be granted is $500. The interest rate
applied is equal to the prime rate published in the Wall Street Journal on the
first business day in June and December of each year. Loans must be repaid over
a period of up to 5 years by means of payroll deductions. In certain cases, the
repayment period may be extended up to 15 years. Interest paid to the Plan on
loans to participants is credited to the borrower's account in the investment
fund to which repayments are made.

Administrative Expenses
               
          Substantially all expenses of administering the Plan are paid by the
plan participants.

B.      Summary of Significant Accounting Policies:

          The accompanying financial statements are prepared on the accrual
basis of accounting.
<PAGE>
                                       6

          The Plan's investment contracts are fully benefit-responsive and are
therefore included in the financial statements at their contract value, defined
as net contributions and deferrals plus interest earned on the underlying
investments at contracted rates. Because the investment contracts are fully
benefit-responsive, contract values approximate fair value. Investments in
mutual funds and the commingled pool are valued at the closing net asset value
reported on the last business day of the year. Investments in securities (common
stocks) traded on a national securities exchange are valued at the last reported
sales price on the last business day of the year. Cash equivalents are
short-term money market instruments and are valued at cost which approximates
fair value.
       
          Security transactions are recorded on trade date. Except for its
investment contracts (Note E), the Plan's investments are held by
bank-administered trust funds. Payables for outstanding security transactions
represent trades which have occurred but have not yet settled.

          The Plan presents in the statement of changes in net assets the net
appreciation (depreciation) in the fair value of its investments which consists
of the realized gains or losses and the unrealized appreciation (depreciation)
on those investments.

          Dividend income is recorded on the ex-dividend date. Income from other
investments is recorded as earned on an accrual basis.

          Benefits are recorded when paid.

          The preparation of the financial statements in conformity with
generally accepted accounting principles requires the plan administrator to make
significant estimates and assumptions that affect the reported amounts of net
assets and liabilities available for benefits at the date of the financial
statements and the changes in net assets available for benefits during the
reporting period and, when applicable, disclosures of contingent assets and
liabilities at the date of the financial statements. Actual results could differ
from the estimates included in the financial statements.

          The Plan provides for various investment options in any combination of
stocks, bonds, fixed income securities, mutual funds and other investment
securities. Investment securities are exposed to various risks, such as interest
rate, market and credit risk. Due to the level of risk associated with certain
investment securities and the level of uncertainty related to changes in the
value of investment securities, it is at least reasonably possible that changes
in risks in the near term would materially affect participants' account balances
and the amounts reported in the statement of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits.

C.      Federal Income Tax Status:

          Given that the Plan was established effective December 17, 1997, the
Plan has not received a tax determination letter to date. Raytheon Company has
submitted an application with the Internal Revenue Service under the 401(b)
regulation of the Internal Revenue Code and expects to receive the determination
letter by December 31, 1998. The plan administrator and the Plan's legal counsel
believe that the Plan is currently designed and being operated in compliance
with the applicable requirements of the Internal Revenue Code. Therefore, no
provision for income taxes has been included in the Plan's financial statements.
<PAGE>
                                       7

D.      Plan Termination:

          Although it has not expressed any intention to do so, the Company
reserves the right under the Plan at any time or times to discontinue its
contributions and to terminate the Plan subject to the provisions of ERISA. In
the event of plan termination, amounts in participants' accounts will be
distributed in a single lump sum; if the participant does not consent to an
immediate distribution, the amount can be transferred to another defined
contribution plan sponsored by the Company.

E.      Investment Contracts:

          The Plan invests in collateralized fixed income investment portfolios
(with no expiration date), three of which are managed by insurance companies and
one of which is managed by an investment management firm. The credited interest
rates are adjusted semiannually to reflect the experienced and anticipated
yields to be earned on such investments, based on their book value. The
annualized average yield and credited interest rates were as follows:

                                                       Annualized
                                                        Average     Credited
                                                         Yield     Interest Rate

For the year ended December 31, 1997:
  Bankers Trust (WBS 92-485)                              6.95%       6.95%
  Metropolitan Life Insurance Company (GIC GA-12908)      6.86%       6.86%
  Metropolitan Life Insurance Company (GIC GA-13659)      6.43%       6.43%
  Prudential Asset Management Company (GIC 917163-001)    6.99%       6.99%


          The contract values are subject to limitations in certain situations
including large workforce reductions and plan termination. 

          In the financial statements, the two Metropolitan Life Insurance
Company contracts are recorded as one investment option.

F.      Related Party Transactions:

          In accordance with the provisions of the Plan, Fidelity Management
Trust Company (the "Trustee") acts as the Plan's agent for purchases and sales
of shares of Raytheon Company common stock. These transactions are performed on
the Master Trust level. For the Master Trust, purchases amounted to $200,689,057
and sales amounted to $102,165,608 for the year ended December 31, 1997.
