Kent Kresa Interviewed on `Market Call'

On April 23, 2002, Kent Kresa, Northrop Grumman chairman and CEO, appeared on
CNNfn's "Market Call" to discuss Northrop Grumman's offer to acquire TRW, Inc.

Each morning, "Market Call" provides investors with all the latest, relevant
stock upgrades and downgrades, the latest performance of overseas markets and
access to roundtable talk about the morning's biggest business news.

RHONDA SCHAFFLER, CNNfn anchor, Market Call: Northrop Grumman's hostile bid for
rival TRW is heating up.

Late Monday, TRW said it had signed a confidentiality agreement to open its
books to an unnamed potential buyer other than Northrop [Grumman]. Northrop
[Grumman] says it will not sign the agreement, in part because of the so-called
"stand-still" clause. That clause typically prevents an interested buyer from
pursing a hostile bid should the target company choose another suitor.

TRW responded by saying it was "deeply disappointed Northrop has chosen to
negotiate the terms of our confidentiality agreement in the press." A TRW
spokesperson tells "Market Call" the company has no further comment on the
matter ahead of it shareholder vote on the deal. That is scheduled [for]
tomorrow.

Joining us from Washington now to shed some light on his side of the story is
chairman and CEO of Northrop Grumman Kent Kresa. It's very good to have you on
MARKET CALL. Thanks for being here.

KENT KRESA: Nice to be here.

SCHAFFLER: You are one aggressive suitor, when it comes to TRW.

KRESA: Maybe that's true. We certainly think the property is terrific.




We love the business they have. It will fit with us very well. So we'd really
like to try and bring this together. As I've said before, if we can't, we have a
great company the way it is. And we'll go on and do wonderful things by
ourselves.

BARRY HYMAN, CNNfn guest host, Market Call: Kent, regarding your acquisition
strategy, how is the Newport News acquisition going? The shipbuilding part of it
seems to have some lower margins this quarter. Can you address that issue?

KRESA: Certainly. The Newport News acquisition is terrific in that it makes us
the largest ship builder in the world, making all classes of ships for the Navy.
The margins are actually quite good. They're not as high as we'd like.

But principally the concern has been in our Gulf port yards, where there have
been some tough contracts that were taken some time ago by Litton. But we're
working our way through those. And I believe the ship business will be excellent
going forward.

SCHAFFLER: Kent, back to TRW for a moment. Right now, that stock is trading at
$54 a share. So Wall Street has been betting that there will be a higher price,
potentially, for TRW. How high are you willing to go?

KRESA: As we've said, this is our bid until we have an opportunity to do due
diligence on this property to see if a higher bid is warranted. I've said that
continuously. We will pay for proper numbers for any property that we acquire,
but we will not overpay. So I frankly don't know that until we have an
opportunity to do due diligence, and hopefully that can occur soon.

HYMAN: Kent, we've heard this story before. But just briefly explain what's the
real significance of what TRW adds to your company.

KRESA: Principally, it's involvement as a space systems prime. Northrop Grumman
is in the space business, principally through the sensors and the data
transmission and the involvement with the data. What TRW brings is the systems
prime part of space, which makes us a principal competitor to the likes of
Lockheed Martin and Boeing.

So we'd be the third largest player in space. That's the main thing. Their
information technology business is again world class, particularly their systems
integration business. As you know,




they've been involved in the missile program of America for years, for decades.
And that's a great capability to add to our capabilities in information
technology.

SCHAFFLER: A bigger-picture view for a moment. We know the defense industry, a
couple of years ago, went through a lot of consolidation. We are in a different
environment now, based on the fact that defense companies are doing well. We
know defense spending is going up. Stocks are performing well. Do we expect to
see mergers continue with or without this deal? What's the bigger picture
industry issue, as far as growth going forward? It would seem, in many ways,
you're in an advantageous position compared to some other executives in other
industries.

KRESA: Certainly, our business is doing very well. The industry is up, as you
know. As you've said correctly, the market seized the importance of this
industry, and we are looking at a much-improved sales picture over the next few
years.

Not only is the defense budget up, but there is great concern, as [you] know,
for homeland security. And that's a budget that really has not put together yet,
but it could add another $30 billion to the total business that we'll all be
competing for.

So the whole industry is in a very positive state. With respect to any mergers
or acquisitions that may go on, all of these things depend on specific interests
of companies. It could happen, and then again, it could not. I think the
important thing is that we have very healthy industry and great prospects.

SCHAFFLER: Kent, one final question. Ahead of that shareholder vote tomorrow,
TRW tells it[s] [share]holders it can increase value by spinning off part of the
company. What is the one message that you want to get out to a TRW shareholder
about why a deal with Northrop Grumman is good for them?

KRESA: The principal issue is for us to have an opportunity to do due diligence
on this property. That is what we've been pushing for very hard. All of these
votes, essentially, are a strong statement to their board to allow a reasonable
due diligence to occur so that we can come to a number, hopefully with the
agreement of their board, that makes sense for this merger.



I think people believe that the concept of breaking up the company into its
individual components is a better idea. That was our original proposal. That is
the one that the TRW board has embraced. So we're all agreeing that this is the
right thing to do for the company for the future.

Our belief is that we can do it quicker and better and we can add more value to
the shareholders than if TRW's board does that independently and spends a couple
of years doing it. But the shareholders are going to speak tomorrow and then in
a week or so for the special vote, which will go on. When we see that, we'll
understand their views and we can move forward. Either we'll continue or we'll
exit.

SCHAFFLER: Kent Kresa of Northrop Grumman, chairman and CEO, thanks for sharing
your thoughts with us.

KRESA: Thank you.
