NOTES TO FINANCIAL STATEMENTS
(unaudited)

Principles of Consolidation
---------------------------

The financial statements include the accounts of the Company and its
subsidiaries except for two insurance subsidiaries. The wholly-owned insurance
subsidiaries and the majority of investments in affiliated companies, which are
not significant individually or in the aggregate, are accounted for by the
equity method.

Environmental Costs
-------------------

During the first quarter of 1997, the Company adopted the provisions of AICPA
Statement of Position (SOP) 96-1, "Environmental Remediation Liabilities". There
was no financial statement effect of the adoption as the Company's previous
method of accounting for environmental costs was in accordance with SOP 96-1.

Discontinued Operations
-----------------------

In September 1996, the Company sold substantially all of the businesses of its
Information Systems and Services segment. The financial statements for the first
six months of 1996 reflect as discontinued operations that segment's operating
results of $27 million. Sales of the discontinued operations were $313 million
for the first six months of 1996.

Acquisition
-----------

In February 1997, the Company completed its purchase of an eighty percent equity
interest in the air bag and steering wheel business of Magna International. The
purchase price of approximately $450 million has been tentatively allocated to
the net assets acquired based on their fair values.

Inventories

Inventories consist of the following:

Earnings Per Share
------------------

Fully diluted earnings per share have been computed based on the weighted
average number of shares of Common Stock outstanding during each period,
including common stock equivalents and assuming the conversion of the Serial
Preference Stock II--Series 1 and 3. Primary earnings per share have been
computed based on the weighted average number of shares of Common Stock
outstanding during each period including common stock equivalents.

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, "Earnings per Share", which is required to be adopted on December 31, 1997.
At that time, the Company will be required to change the method currently used
to compute earnings per share and to restate all prior periods. Under the new
requirements for calculating primary earnings per share, the dilutive effect of
stock options will be excluded. The impact is expected to result in a $.03 and
$.02 per share increase in primary earnings per share for the second quarter    
ended June 30, 1997 and June 30, 1996, respectively. There is an immaterial
impact of Statement No. 128 on the calculation of fully diluted earnings per
share for these quarters.

In April 1997, the number of authorized shares of TRW Common Stock was increased
from 250,000,000 to 500,000,000 shares.

</TABLE>


The Company considers all highly liquid investments purchased with a maturity of
three months or less to be cash equivalents.

Other Contingencies
-------------------

During 1996, the Company was advised by the Department of Justice ("DOJ") that
it had been named as a defendant in two lawsuits brought by a former employee
and filed under seal in 1994 and 1995, respectively, in the United States
District Court for the Central District of California under the QUI TAM
provisions of the civil False Claims Act. The Act permits an individual to bring
suit in the name of the United States and share in any recovery. The allegations
in the lawsuit relate to the classification of costs incurred by the Company
that were charged to certain of its federal contracts. Under the law, the
government must investigate the allegations and determine whether it wishes to
intervene and take responsibility for the lawsuits. The actions remain under
seal until the government completes its investigations and determines whether to
intervene. However, permission from the court has been obtained by the Company
to make the disclosures contained herein. The Company is cooperating with the
DOJ's investigation and is engaged in ongoing discussions with them regarding
the allegations. The Company cannot presently predict the outcome of these
matters, although management believes that the Company would have meritorious
defenses if either the government decides to pursue the lawsuits or the former
employee decides to do so without government participation.

Interim Statements
------------------

The financial statements are based in part on approximations and are subject to
adjustments that may develop, such as unsettled contract and renegotiation
matters and matters that arise in connection with the annual audit of the
financial statements; however, in the opinion of management, all adjustments
(which consist of normal recurring accruals) necessary for a fair presentation
of the results of operations for the periods presented have been included.
Results of operations for any interim period are not necessarily indicative of
the results to be expected for the full year.

</TABLE>

The increase in sales for the second quarter and first six months of 1997 was
primarily due to the sales contribution from the acquisitions of air bag and
steering wheel operations, and from higher volume in the Automotive and Space
and Defense segments. The sales increase was moderated by the effect of a strong
U.S. dollar.

The higher operating profit was due to the acquisitions, continued
cost-reduction efforts, and profit from the higher sales volume in the
Automotive and Space and Defense segments, partially offset by the effect of
lower pricing in the Automotive segment. Operating profit for the first six
months of 1996 included a $15 million before tax charge related to the initial
application of Statement of Financial Accounting Standards (SFAS) No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of."

Net earnings for the first six months of 1996 included a $12 million benefit
from an insurance claim settlement primarily related to previously divested
businesses, offset by a $13 million noncash charge related to the initial
application of SFAS No. 121.

Interest expense was $37 million for the first six months of 1997 compared to
$39 million for the first half of 1996. The decrease in interest expense was
primarily due to lower foreign debt levels.

</TABLE>

Sales and operating profit for the second quarter and first six months of 1997
increased primarily due to the successful conversion of recent contract awards
into revenue growth as well as strong ongoing program performance.

LIQUIDITY AND FINANCIAL POSITION

In the first six months of 1997, cash flow provided by operating activities of
$358 million, a net increase in debt of $221 million, and a net increase of $18
million in other items were used to fund business acquisitions of $415 million,
capital expenditures of $228 million, reacquisition of common stock of $179
million, and dividend payments of $78 million. As a result, cash and cash
equivalents decreased by $303 million.


<PAGE>   11



Net debt (short-term debt, the current portion of long-term debt and long-term
debt less cash and cash equivalents) was $779 million at June 30, 1997, compared
to $196 million at December 31, 1996. The ratio of net debt to total capital
(net debt, minority interests and shareholders' investment) at June 30, 1997 was
25 percent compared to 8 percent at December 31, 1996.

During July 1997, the Company issued $30 million in medium-term notes under its
shelf registration statements. The notes were used to refinance short-term debt.
After this issuance, $420 million remains available for borrowing under the
Company's shelf registration statements.

During the second quarter of 1997, the company requested an amendment of the
terms of its U.S. and multicurrency revolving credit agreements to extend the
expiration date of the agreements from July 1, 2001 to July 1, 2002. Also, one
additional bank will join the bank group providing the U.S revolving credit
agreement and one additional bank will join the bank group providing the
multicurrency revolving credit agreement. The amendment is expected to be
executed in August 1997.

During the first six months of 1997, 3,529,133 shares of TRW Common Stock were
repurchased for approximately $184 million, of which approximately $5 million
was settled in July.

Management believes that funds generated from operations and existing borrowing
capacity will be adequate to fund the Company's current share repurchase program
and to support and finance planned growth, capital expenditures,
company-sponsored research and development programs and dividends payments to
shareholders.

OTHER MATTERS

During 1996, the Company was advised by the Department of Justice that it had
been named as a defendant in two lawsuits brought by a former employee and filed
under seal under the QUI TAM provisions of the civil False Claims Act. See
"Other Contingencies" note in the Notes to Financial Statements for further
information.

PART II. OTHER INFORMATION


Item 1.  Legal Proceedings.
         ------------------

         The United States Environmental Protection Agency has issued a notice
of violation to the Company under the Clean Air Act with respect to air
emissions at the former Izumi Industries, Corporation, Inc. facility in Yaphank,
New York, which TRW acquired in November, 1996. The New York State Department of
Environmental Conservation has informed TRW that it may initiate administrative
proceedings against the Company under the New York Environmental Conservation
Law with respect to such emissions. TRW could be liable for civil penalties and
fines and other relief with respect to such matters which, if imposed, are not
expected to have a material effect on TRW's financial position.
