                                                            [TRW Letterhead]



March 14, 2002

Dear TRW Employee:

TRW announced yesterday that after careful consideration, our Board of
Directors unanimously determined that Northrop Grumman's $47 per share
exchange offer is financially inadequate. Accordingly, the board recommended
that shareholders reject Northrop Grumman's offer and not exchange their
shares.

Like the board, I am absolutely convinced that we can deliver greater value to
TRW shareholders through the continued execution of our strategic plan, which
includes accelerating our deleveraging initiatives and exploring additional
actions, including the spin-off of our Automotive business and the potential
sale of Aeronautical Systems.

Aeronautical Systems, Space & Electronics, and Systems are all well-positioned
to benefit from the positive economic trends across the aerospace and defense
businesses. We are all committed to aggressive cost-cutting initiatives,
productivity improvements and enhancing relationships with our customers. And,
we're on track to meet or exceed our 2002 commitments.

The fundamental key to keeping our performance on track is to maintain a focus
on meeting commitments, especially to our customers. Your performance in this
area throughout this period of uncertainty has been impressive and remains a
very important factor in our ability to capitalize on the opportunities
present in our markets. We need to sustain that focus, implement our business
strategy and maintain our world-class performance.

I want to again reaffirm to you that although there will be many challenging
actions ahead, we continue to keep your interests as both employees and
shareholders as a top priority. We will keep you informed as important
developments occur. On behalf of the board and senior management, I thank you
for your continued focus on the business and on serving our customers.

Tim Hannemann

Dear Aeronautical Systems Employee:

As you may have read, TRW announced today that after careful consideration,
our board of directors unanimously determined that Northrop Grumman's $47 per
share exchange offer is financially inadequate. Accordingly, the board has
recommended that shareholders reject Northrop Grumman's offer and not exchange
their shares.

TRW's senior management and board of directors believe that we can deliver
greater value to TRW shareholders through the continued execution of our
strategic plan, which includes accelerating TRW's deleveraging initiatives and
exploring additional actions, including the spin-off of our Automotive
business.

To help optimize TRW's strategic and financial flexibility, TRW's board is
considering, among other alternatives, the possible sale of Aeronautical
Systems. There can be no assurance that any transaction will result, but
combining with a company more strategically focused on the aeronautical
industry could substantially enhance the long-term growth prospects for
Aeronautical Systems.

As an organization, we must maintain our focus on meeting our commitments,
especially to our customers. Aeronautical Systems is in a strong position to
capitalize on the positive economic trends across the aerospace business.
Maintaining our focus will further strengthen our business and advance our
long-term goals - helping us achieve value-creating growth, and solidifying
our position in the top ranks of the aeronautical business.

I look forward to a very promising future for our organization. I am confident
that, together, we can stay focused on our priorities, and successfully
realize our full potential.

Dear Automotive Employee:

I want to give you my perspective on two key announcements our company made
this morning.

First, after careful consideration, TRW's Board of Directors unanimously
determined that Northrop Grumman's $47 per share exchange offer is financially
inadequate. As such, the board recommends that TRW shareholders reject
Northrop Grumman's offer and not exchange their shares. TRW is confident that
by executing its strategic plan, we will deliver more value to TRW
shareholders than the Northrop Grumman offer.

This brings me to the second announcement made today: our plan to accelerate
TRW's deleveraging initiative and explore the spin-off of Automotive. TRW has
targeted completion of the spin-off of the Automotive business in
approximately six to nine months.

Late last year, we consolidated all Automotive units, and this announcement is
the next step in the creation of a stronger, more competitive, more
customer-focused, and more flexible business. As an independent, publicly
traded company, the Automotive business will have the strategic and financial
flexibility necessary to capture value against best-in-class industry
benchmarks.

In my years of involvement in the industry and with various parts of our
automotive business, I have had many opportunities to experience, first-hand,
the depth of talent and dedication that exists among our 65,000 employees
worldwide. Because of our collective efforts and expertise, we are able to
offer a broad range of leading-edge systems to today's automakers who are
increasingly looking to enhance their vehicle lines with sophisticated
products that represent real value. Clearly, our business, which is at the
forefront of technology, is well positioned for success and growth.

I want to assure you of my commitment to Automotive and ask for your continued
support and cooperation as we enter this new phase together. To meet our goals
it is imperative that you remain focused on our business plan. This includes
driving Six Sigma, accelerating lean manufacturing, sharing best practices and
providing our customers with the outstanding service they have come to expect
from us.

We will work hard to keep you updated over the coming months. I look forward
to your support as we embark on this exciting new era in the history of our
company.
