                                 TO ACCOMPANY 1998 FORM 5500
                            ANNUAL REPORT OF EMPLOYEE BENEFIT PLAN
                                      UNDER ERISA OF 1974

                             for the Year ended December 31, 1998


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

                        Report of Independent Accountants

To the Participants and Administrator of
the Raytheon Savings and Investment Plan for Puerto Rico Based Employees

In our opinion, the accompanying statements of net assets available for plan
benefits and the related statement of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
benefits of the Raytheon Savings and Investment Plan for Puerto Rico Based
Employees (the "Plan") at December 31, 1998 and 1997, and the changes in net
assets available for benefits for the year ended December 31, 1998 in conformity
with generally accepted accounting principles. 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 of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                      RAYTHEON SAVINGS AND INVESTMENT PLAN
                        FOR PUERTO RICO BASED EMPLOYEES
                         NOTES TO FINANCIAL STATEMENTS

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 combined with the investments of other similar
defined contribution plans of Raytheon Company into the Raytheon Company Master
Trust for Defined Contribution Plans ("Master Trust"). 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. For 1998, the annual employee
deferral for a participant cannot exceed the lesser of $8,000 or 10% of a
participant's annual compensation, minus any contributions to Puerto Rico
qualified Individual Retirement Accounts. 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) the
Fidelity Equity Income Fund which invests in shares of a mutual fund consisting
primarily of income-producing equity securities, (c) a Raytheon Common Stock
Fund which invests in shares of Raytheon Company 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) the Fidelity Balanced
Fund which invests in shares of a mutual fund consisting primarily of equity
securities, bonds and money market instruments, (f) the Fidelity Magellan Fund,
a growth fund which invests primarily in equities of companies of all types and
sizes, and (g) the Fidelity Blue Chip Fund, a growth fund which invests
primarily in equities of well known and established companies. Dividends and
distributions from investments of the Fidelity Equity Income Fund, the Raytheon
Common Stock Fund, the Stock Index Fund, the Fidelity Balanced Fund, the
Fidelity Magellan Fund and the Fidelity Blue Chip Fund are reinvested in their
respective funds; stock dividends, stock splits and similar changes are also
reflected in the funds.

                                       6

          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 completion of five years of service
or after 3 years of 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
part of deferrals. On termination of employment, a participant will receive a
lump-sum distribution. If the vested account is valued in excess of $3,500, the
participant has the option 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

Certain expenses of administering the Plan are paid by the plan participants.


                                       7

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. Contract value approximates 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. Participant loans are valued at cost, which approximates fair value.

Security transactions are recorded on the 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. Investment income
includes both dividend and interest income.

Benefits are recorded when paid.

     Certain items in the 1997 financial statements have been reclassified to
conform to the 1998 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.


                                       8

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 which are
managed by insurance companies and investment management firms. 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:


                                       9

                                               Annualized        Credited

     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:

The Plan's trustee is Fidelity Management Trust Company (the "Trustee"). The
Trustee holds the funds for the Plan and is responsible for managing the Plan's
investment assets, executing all investment transactions, recording approved
transactions, and, therefore these transactions qualify as party-in-interest.

In accordance with the provisions of the Plan, the "Trustee" acts as the Plan's
agent for purchases and sales of shares of Raytheon Company common stock. These
transactions are performed on a Master Trust level. For the Master Trust,
purchases amounted to $288,116,995 and sales amounted to $257,878,566 for the
year ended December 31, 1998.

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.
