Litton supplies advanced electronic and information systems and is a primary
builder of large surface combatant ships for the U.S. Navy. Litton is also a
global supplier of electronic components and materials to the
telecommunications, industrial and computer markets. Our businesses are reported
in four business segments: Advanced Electronics, Information Systems, Ship
Systems and Electronic Components and Materials. We were founded in 1953 and

Litton is a Delaware corporation, and our principal executive offices are at
21240 Burbank Boulevard, Woodland Hills, California 91367-6675, telephone (818)
598-5000.

ADVANCED ELECTRONICS

The Advanced Electronics segment is a major supplier and integrator of
electronic systems and related services to the U.S. and international military
and commercial markets. The principal businesses comprising the Advanced
Electronics segment are navigation, guidance and control systems, marine
electronics and electronic warfare systems. The primary products include
inertial navigation systems, IFF (identification friend or foe) systems, marine
bridge, steering and machinery control systems, displays, computers, laser range
finders and target designators, threat warning and electro-optical systems,
microwave tubes and military air traffic control systems. We also provide and
integrate shipboard engineering, information and communications control systems
and avionics systems.

INFORMATION SYSTEMS

The Information Systems segment is a leading supplier of information systems,
technology and related services to the U.S. Government (for both defense and
non-defense applications), as well as state, local and commercial customers. In
addition to systems integration and networking solutions, this segment supplies
tactical command, control and communication systems to military customers and
provides systems and related services and support to other non-defense
governmental and commercial customers.

SHIP SYSTEMS

The Ship Systems segment is engaged in the building of large multimission
surface combatant ships and is a provider of overhaul, repair, modernization,
ship design and engineering services. Avondale Industries, Inc. ("Avondale"),
acquired on August 2, 1999, is reported with this segment.

backpanel assemblies, printed circuit boards, specialty motors, slip rings and
signal, power and fiber optic connectors and produces soldering materials, laser

commercial markets worldwide.

                                USE OF PROCEEDS

We will not receive any cash proceeds from the issuance of the Exchange Notes.
We used the net proceeds from the original sale of the Initial Notes on October
13, 1999, to refinance then outstanding commercial paper used to fund the
acquisition of Avondale.

- ------------------------------
(1) Results for fiscal year 1999 were impacted by non-recurring and special
    charges totaling $116.8 million pre-tax and $77.4 million after tax. Results
    for the six months ended January 31, 2000

                                        6
<PAGE>   7

    were impacted by $34 million in cost growth provisions recorded for two
    systems development programs for integrated electronics which was offset by
    the reversal of $12.5 million in contract losses no longer required as a
    result of the sale of the Litton Enterprise Solutions, Inc. subsidiary
    ("LES"). The sale of LES resulted in a gain of $7.6 million and special
    charges of $6.3 million primarily for additional noncancelable software and
    hardware lease obligations.

(2) The Ratio of Earnings to Fixed Charges is computed by dividing the sum of
    historical Earnings before Taxes on Income and Fixed Charges, as adjusted,
    by Fixed Charges. Fixed Charges represent interest (including capitalized
    interest) and amortization of debt discount and expense and that portion of
    rental expense which is deemed to be representative of interest.

(3) In addition, our PRC Inc. (acquired in fiscal year 1996) and TASC, Inc.
    (acquired in fiscal year 1998) subsidiaries had unfunded backlog with
    potential contract values totaling approximately $2.2 billion and $2.0
    billion at January 31, 2000 and January 31, 1999, respectively, and $2.2
    billion, $1.8 billion, $1.5 billion and $1 billion for fiscal years 1999,
    1998, 1997 and 1996, respectively.

(4) Effective August 1, 1999, Litton adopted Statement of Position 97-3 ("SOP
    97-3"), "Accounting by Insurance and Other Enterprises for Insurance Related
    Assessments", which required a change in the accounting for assessments by
    the workers' compensation second-injury fund administered by the Department
    of Labor. The resulting cumulative effect of a change in accounting
    principle was a charge of $2.8 million, net of tax.

            DESCRIPTION OF THE INITIAL NOTES AND THE EXCHANGE NOTES

The Initial Notes were, and the Exchange Notes will be, issued as a separate
series of our senior debt securities under an indenture, dated as of April 13,
1998 (the "Indenture"), between us and The Bank of New York, as trustee. Because
this is a summary, it does not contain all the information that may be important
to you. The following description of specific terms of the Notes is qualified in
its entirety by reference to the provisions of the Indenture. Capitalized and
other terms not otherwise defined in this Prospectus shall have the meanings
given to them in the Indenture. You may obtain a copy of the Indenture from
Litton upon request. See "Where You Can Find More Information" in this
Prospectus.

The Indenture does not limit the aggregate principal amount of debt securities
which may be issued thereunder and provides that debt securities may be issued
thereunder from time to time in one or more series.

The Initial Notes were, and the Exchange Notes will be, issued in an aggregate
principal amount of $400,000,000. The Initial Notes were, and the Exchange Notes
will be, issued only in registered form, without coupons, in denominations of
$1,000 and integral multiples of $1,000. The Initial Notes were, and the
Exchange Notes will be, unsecured senior obligations of Litton and, as such,
will rank pari passu in right of payment with all other existing and future
senior indebtedness of Litton and senior in right of payment to all existing and
future subordinated indebtedness of Litton. As of January 31, 2000, Litton had
approximately $1.2 billion in aggregate principal amount of indebtedness
outstanding which ranked pari passu in right of payment with the Initial Notes
and the Exchange Notes. See "Capitalization" in this Prospectus.

Further references in this Prospectus to the "Notes" are to the Initial Notes

OPTIONAL REDEMPTION

We may, at our option, redeem the Notes, in whole or in part, at any time at a
redemption price equal to the greater of (i) 100% of the principal amount of the
Notes to be redeemed, and (ii) as determined by the Quotation Agent, the sum of
the present values of the remaining scheduled payments of principal and
                                        8
<PAGE>   9

interest in respect of the Notes to be redeemed (not including any portion of
such payments of interest accrued as of the date of redemption) discounted to
the date of redemption on a semi-annual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Adjusted Treasury Rate plus 15 basis
points plus, in each case, accrued interest to the date of redemption.

"Adjusted Treasury Rate" means, with respect to any redemption date, the rate
per year equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
that redemption date.

"Comparable Treasury Issue" means the United States Treasury security selected
by the Quotation Agent as having a maturity comparable to the remaining term of
the Notes that would be utilized, at the time of selection and in accordance
with customary financial practice, in pricing new issues of corporate debt
securities of comparable maturity to the remaining term of the Notes.

"Comparable Treasury Price" means, with respect to any redemption date, (i) the
average of the Reference Treasury Dealer Quotations for that redemption date,
after excluding the highest and lowest of the Reference Treasury Dealer
Quotations, or (ii) if the trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of all Reference Treasury Dealer
Quotations so received.

"Quotation Agent" means the Reference Treasury Dealer appointed by Litton.

"Reference Treasury Dealer" means (i) each of J.P. Morgan Securities Inc.,
Credit Suisse First Boston Corporation, Banc of America Securities LLC, BNY
Capital Markets, Inc., Chase Securities Inc. and Salomon Smith Barney Inc. and
their respective successors unless any of them ceases to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), in
which case we shall substitute another Primary Treasury Dealer, and (ii) any
other Primary Treasury Dealer selected by Litton.

"Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by Litton,
of the bid and asked prices for the Comparable Treasury Issue (expressed in each
case as a percentage of its principal amount) quoted in writing to the trustee
by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third
business day preceding that redemption date.

Notice of any redemption will be mailed at least 30 days but not more than 60
days before the redemption date to each holder of the Notes to be redeemed.
Unless we default in payment of the redemption price, on and after the
redemption date, interest will cease to accrue on the Notes or portions of the
Notes called for redemption.

FURTHER ISSUES

The Notes will be issued in an initial aggregate principal amount of
$400,000,000. However, we may from time to time, without the consent of the
existing holders of the Notes, create and issue additional Notes under the
Indenture having the same terms and conditions as the Notes in all respects
except for issue date and issue price. Additional Notes issued in this manner
will be consolidated with and form a single series with the previously
outstanding Notes.

BOOK-ENTRY SYSTEM; DELIVERY AND FORM

The Notes will be represented by one or more global notes in fully registered
form.

The global notes will be deposited with, or on behalf of, DTC and registered in
the name of its nominee, Cede & Co. Beneficial interests in the global notes
will be shown on, and transfers thereof will be effected only through, records
maintained in book-entry form by DTC (with respect to its participants) and its
participants.

                                        9
<PAGE>   10

Ownership of interests in the global notes will be limited to persons who have
accounts with DTC or persons who have accounts through participants ("indirect
participants") in DTC. Ownership of beneficial interests in the global notes
will be shown on, and the transfer of that ownership will be effected only
through, records maintained by DTC (with respect to interests of participants)
and the records of participants (with respect to interests of indirect
participants).

The laws of some countries and some states in the United States may require that
certain purchasers of any securities take physical delivery of such securities
in definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge the book-entry interests in the global notes.

So long as DTC or its nominee is the holder of the global notes, DTC or such
nominee, as the case may be, will be considered the sole holder of the global
notes for all purposes under the Indenture and the Notes. Except as described
under "Definitive Registered Notes," participants or indirect participants will
not be entitled to have the Notes registered in their names, will not receive or
be entitled to receive physical delivery of Notes in definitive form and will
not be considered the owners or holders thereof under the Indenture.
Accordingly, each direct or indirect participant must rely on the procedures of
the DTC and, if that person is an indirect participant in DTC, on the procedures
of the participant in DTC, through which that person owns its interest, to
exercise any rights and remedies of a holder under the Indenture.

INFORMATION CONCERNING DTC

DTC has advised Litton that:

DTC is a limited purpose trust company organized under the New York Banking Law,
a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
was created to hold securities of its participants and to facilitate the
clearance and settlement of transactions among its participants in such
securities through electronic book-entry changes in accounts of the
participants, thereby eliminating the need for physical movement of securities
certificates. DTC participants include securities brokers and dealers (including
the Initial Purchasers), banks, trust companies, clearing corporations and
certain other organizations, some of whom (and/or their representatives) own
DTC. Access to the DTC book-entry system is also available to indirect
participants (as defined above), such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly.

Although DTC has agreed to the procedures described in this Prospectus to
facilitate transfers of interests in the global notes among participants in DTC,
it is under no obligation to perform or to continue to perform such procedures,
and such procedures may be discontinued at any time. Neither Litton nor the
trustee will have any responsibility for the performance by DTC or its
respective participants or indirect participants of their respective obligations
under the rules and procedures governing their operations.

SAME-DAY SETTLEMENT AND PAYMENT

Settlement for the Notes represented by the global notes will be made in
immediately available funds. All payments of principal and interest on the
global notes will be made in immediately available funds.

The Notes will trade in DTC's same-day funds settlement system until maturity,
and secondary market trading activity in the Notes will therefore be required by
DTC to settle in immediately available funds.

DEFINITIVE REGISTERED NOTES

Owners of book-entry interests in the global notes will receive individual
certificated Notes in fully registered form ("Definitive Registered Notes") only
in the following circumstances:

- - if DTC notifies Litton or the book-entry depository in writing that it (or its
  nominee) is unwilling or unable to continue to act as a depository registered
  under the Exchange Act and a successor depository

                                       10
<PAGE>   11

  registered as a clearing agency under the Exchange Act (in the case of DTC) or
  successor registered as a clearing agency under the Exchange Act is not
  appointed by Litton within 90 days; or

- - at any time if Litton determines that the global notes for Notes should be
  exchanged for Definitive Registered Notes (in whole but not in part).

In addition to the foregoing, during the continuance of an Event of Default (as
defined below), holders of book-entry interests will be entitled to request and
receive Definitive Registered Notes. Such Definitive Registered Notes will be
issued to and registered in the name of, or as directed by, that person only
upon the request in writing made through a DTC participant.

Any Definitive Registered Notes will be issued in fully registered form in
denomination of $1,000 principal amount and integral multiples of $1,000. To the
extent permitted by law, Litton, the trustee and any paying agent shall be
entitled to treat the person in whose name any Definitive Registered Note is
registered as the absolute owner thereof. While any global note is outstanding,
holders of Definitive Registered Notes may exchange their Definitive Registered
Notes for a corresponding book-entry interest in that global note by
surrendering their Definitive Registered Notes to the trustee and providing the
certificates and opinions required by the Indenture. The trustee will make the
appropriate adjustments to the global note underlying that book-entry interest
to reflect any issue or surrender of Definitive Registered Notes. The Indenture
contains provisions relating to the maintenance by a registrar of registers
reflecting ownership of Definitive Registered Notes, if any, and other
provisions customary for a debt security listed on the register maintained by
the registrar. Payment of principal and interest on each Definitive Registered
Note will be made to the holder appearing on the applicable register at the
close of business on the record date at his address shown on the applicable
register on the record date.

PAYMENTS ON THE NOTES

Payments of any amounts owing in respect of the global notes will be made
through one or more paying agents appointed under the Indenture to DTC as the
holder of the global notes. Initially, the paying agent for the Notes will be
The Bank of New York, as trustee.

Litton expects that DTC or its nominee, upon receipt of any payment made in
respect of the global notes, will credit its participants' accounts with such
payments in amounts proportionate to their respective interest in the principal
amount of such global note as shown on the records of DTC or its nominee.
Payments by participants to owners of interests held through such participants
will be governed by standing customer instructions and customary practices of
the participants.

None of Litton, the trustee or any paying agent will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of book-entry interests or for maintaining, supervising or reviewing any records
relating to such book-entry interests or beneficial ownership interests.

CERTAIN COVENANTS

Other than as described below, the Indenture does not contain any provisions
that would limit our ability to incur indebtedness or that would afford holders
of Notes protection in the event of a sudden and significant decline in the
credit quality of Litton or a takeover, recapitalization or highly leveraged or
similar transaction involving Litton.

                                       11
<PAGE>   12

Limitation on Liens; Sale Leaseback

Litton will not, and will not permit any subsidiary to, create, assume or suffer
to exist any lien on any Restricted Property (as defined below), to secure any
debt of Litton, any subsidiary or any other person, or permit any subsidiary so
to do, without securing the Notes equally and ratably with such debt for so long
as such debt shall be so secured, subject to certain exceptions. Exceptions
include:

- - existing liens or liens on facilities of corporations at the time they become
  subsidiaries;

- - liens existing on facilities when acquired, or incurred to finance the
  purchase price, construction or improvement thereof;

- - certain liens required by contracts with, and in favor of, governmental
  entities; and

- - liens otherwise prohibited by such covenant, securing indebtedness which,
  together with the aggregate amount of outstanding indebtedness secured by
  liens otherwise prohibited by such covenant and the value of certain sale and
  leaseback transactions, does not exceed 15% of Litton's consolidated net
  tangible assets (defined as total assets less current liabilities and
  intangible assets).

In addition, Litton will not, and will not permit any subsidiary to, enter into
any sale and leaseback transaction covering any Restricted Property unless (i)
Litton would be entitled under the provisions described above to incur debt
equal to the value of such sale and leaseback transaction, secured by liens on
the facilities to be leased, without equally and ratably securing the Notes, or
(ii) Litton, during the six months following the effective date of such sale and
leaseback transaction, applies an amount equal to the value of such sale and
leaseback transaction to the voluntary retirement of long-term indebtedness or
to the acquisition of Restricted Property.

"Restricted Property" is defined as (i) any manufacturing facility (or portion
thereof) owned or leased by Litton or any subsidiary and located within the
continental United States which, in the opinion of the Board of Directors of
Litton, is of material importance to the business of Litton and its subsidiaries
taken as a whole, but no such manufacturing facility (or portion thereof) shall
be deemed of material importance if its gross book value (before deducting
accumulated depreciation) is less than 2% of Litton's consolidated net tangible
assets, or (ii) any shares of capital stock or indebtedness of any subsidiary
owning any such manufacturing facility.

Consolidation, Merger and Sale of Assets

We may, without the consent of the holders of the Notes or any other outstanding
debt securities, consolidate with, merger into or be merged into, or transfer or
lease our property and assets substantially as an entirety to another entity.
However, we may only do this if: (i) the successor entity is a corporation and
assumes by supplemental indenture all of our obligations under the Notes, any
other outstanding debt securities and the Indenture, and (ii) after giving
effect to the transaction, no Default or Event of Default (as defined below) has
occurred and is continuing. After that time, all of our obligations under the
Notes, any other outstanding debt securities and the Indenture terminate.

EVENTS OF DEFAULT

Any one of the following is an "Event of Default" with respect to any series of
debt securities, including the Notes:

- - if we default in the payment of interest on the debt securities of such
  series, and such default continues for 30 days;

- - if we default in the payment of the principal of any debt security of such
  series;

- - if we fail to comply with any of our other agreements in the debt securities
  of such series, in the Indenture or in any supplemental indenture under which
  the debt securities of such series were issued, which failure continues for 60
  days after we receive notice from the trustee or the holders of at least 25%
  in principal amount of all of the outstanding debt securities of that series;
  and

- - if certain events of bankruptcy or insolvency occur with respect to Litton.

                                       12
<PAGE>   13

If an Event of Default with respect to the debt securities of any series occurs
and is continuing, the trustee or the holders of at least 25% in principal
amount of all of the outstanding debt securities of that series may declare the
principal (or, if the debt securities of that series are original issue discount
securities, such portion of the principal amount as may be specified in the
terms of that series) of all the debt securities of that series to be due and
payable. When such declaration is made, such principal (or, in the case of
original issue discount securities, such specified amount) will be immediately
due and payable. The holders of a majority in principal amount of debt
securities of that series may rescind such declaration and its consequences if
the rescission would not conflict with any judgment or decree and if all
existing events of default have been cured or waived (other than nonpayment of
principal or interest that has become due solely as a result of acceleration).

Holders of debt securities may not enforce the Indenture, or the debt securities
except as provided in the Indenture. The trustee may require indemnity
satisfactory to it before it enforces the Indenture or the debt securities.
Subject to certain limitations, the holders of more than 50% in principal amount
of the debt securities of each series affected (with each series voting as a
class) may direct the time, method and place of conducting any proceeding for
any remedy available to the trustee or exercising any trust or power of the
trustee. The trustee may withhold from holders of debt securities notice of any
continuing default (except a default in the payment of principal or interest) if
it determines that withholding notice is in their interests.

AMENDMENT AND WAIVER

With the consent of the holders of more than 50% of the principal amount of the
outstanding debt securities of each series that will be affected (with each
series voting as a class), Litton and the trustee may amend or supplement the
Indenture or modify the rights of the holders of debt securities of each series.
Such majority holders may also waive compliance by us with any provision of the
Indenture, any supplemental indenture or the debt securities of any such series
except a default in the payment of principal or interest. However, without the
consent of the holder of each debt security affected, an amendment or waiver may
not:

- - reduce the amount of debt securities whose holders must consent to an
  amendment or waiver;

- - change the rate or the time for payment of interest;

- - change the principal or the fixed maturity;

- - waive a default in the payment of principal or interest;

- - make any debt securities payable in a different currency; or

- - make any change in the provisions of the Indenture concerning (i) waiver of
  existing defaults; (ii) rights of holders of debt securities to receive
  payment; or (iii) amendments and waivers with consent of holders of debt
  securities.

We and the trustee may amend or supplement the Indenture without the consent of
any holder of any of the debt securities to cure any ambiguity, defect or
inconsistency in the Indenture, the debt securities or for certain other limited
purposes, including to make any change that does not adversely affect the rights
of any holder of debt securities.

DEFEASANCE AND COVENANT DEFEASANCE

The Indenture provides that we (a) may be discharged from our obligations in
respect of the debt securities of a specified series including the Notes
("defeasance and discharge"), or (b) may cease to comply with certain
restrictive covenants ("covenant defeasance") including those described under
"Certain Covenants -- Limitation on Liens; Sale Leaseback" and "Certain
Covenants -- Consolidation, Merger and Sale of Assets", when we have irrevocably
deposited with the trustee, in trust, (i) sufficient funds to pay the principal
of (and premium, if any) and interest to stated maturity (or redemption) on, the
debt securities of such series, or (ii) such amount of direct obligations of, or
obligations guaranteed by,
                                       13
<PAGE>   14

the government which issued the currency in which the debt securities are
denominated, as will, together with the predetermined and certain income to
accrue thereon without consideration of any reinvestment, be sufficient to pay
when due the principal of (and premium, if any) and interest to stated maturity
(or redemption) on, the debt securities of such series. Such defeasance and
discharge and covenant defeasance are conditioned upon, among other things, our
delivery of an opinion of counsel that the holders of the debt securities of
such series will not recognize income, gain or loss for United States Federal
income tax purposes as a result of such defeasance, and will be subject to tax
in the same manner as if no defeasance and discharge or covenant defeasance, as
the case may be, had occurred.

GOVERNING LAW

The Indenture and the Notes will be governed by, and construed in accordance
with, the laws of the State of New York.

CONCERNING THE TRUSTEE

We maintain banking and other business relationships in the ordinary course of
business with The Bank of New York.

                                 EXCHANGE OFFER

GENERAL

We hereby offer, upon the terms and subject to the conditions set forth in this
Prospectus and in the accompanying Letter of Transmittal, which together
constitute the Exchange Offer, to exchange up to $400,000,000 aggregate
principal amount of Exchange Notes due 2009 for the same aggregate principal
amounts of Initial Notes due 2009, properly tendered on or prior to the
Expiration Date and not withdrawn as permitted pursuant to the procedures
described below. We are making the Exchange Offer for all of the Initial Notes
due 2009; the total aggregate principal amount of Initial Notes due 2009 and
Exchange Notes due 2009 will not exceed $400,000,000.

PURPOSE OF THE EXCHANGE OFFER

Under the terms of the Registration Rights Agreement, dated as of October 13,
1999, among Litton and J.P. Morgan & Co., Credit Suisse First Boston, Banc of
America Securities LLC, BNY Capital Markets, Inc., Chase Securities Inc. and
Salomon Smith Barney as representatives of the Initial Purchasers of the Initial
Notes, we are required to file with the SEC and use our reasonable best efforts
to cause to become effective a registration statement with respect to issues of
Exchange Notes identical in all material respects to the Initial Notes and, upon
becoming effective, to offer the Holders of the Initial Notes of each series the
opportunity to exchange their Initial Notes for the Exchange Notes of identical
series.

We will be entitled to close the Exchange Offer provided that we have accepted
all Initial Notes that have been validly tendered in accordance with the terms
of the Exchange Offer. Initial Notes not tendered in the Exchange Offer shall
bear interest at the same rates in effect at the time of issuance of the Initial
Notes.

EXPIRATION DATE; EXTENSIONS; TERMINATION; AMENDMENTS

The Exchange Offer will expire at 5:00 p.m., New York City time, on April 14,
2000, unless we, in our sole discretion, extend the period of time described
below for which the Exchange Offer is open. The expiration date will be at least
30 days after the commencement of the Exchange Offer, or longer if required by
applicable law. We expressly reserve the right, at any time or from time to
time, to extend the period of time during which the Exchange Offer is open, and
as a result delay acceptance for exchange of any Initial Notes by giving oral
notice, which shall be confirmed in writing or written notice to the Exchange
Agent and by giving written notice of this extension to the holders of the
Initial Notes or by timely public announcement communicated, unless otherwise
required by applicable law or regulation, by making a release through the Dow
Jones News Service, in each case, no later than 9:00 a.m. New York City time, on
the next business day after the previously scheduled expiration date. Such
announcement may state that we are extending the Exchange Offer for a specified
period of time. During any such extension, all Initial Notes previously tendered
will remain subject to the Exchange Offer.

In addition, we expressly reserve the right to terminate or amend the Exchange
Offer and not to accept for exchange any Initial Notes not previously accepted
for exchange upon the occurrence of any of the events specified below under
"Certain Conditions to the Exchange Offer". If any such termination or amendment
occurs, we will notify the Exchange Agent and will either issue a press release
or give oral or written notice to the holders of the Initial Notes as promptly
as practicable.

PROCEDURES FOR TENDERING INITIAL NOTES

Your tender to us of Initial Notes as set forth below and the acceptance by us
of such tender will constitute a binding agreement between you and us upon the
terms and subject to the conditions set forth in this prospectus and in the
accompanying Letter of Transmittal.

You may tender Initial Notes by (1) properly completing and signing the Letter
of Transmittal or a facsimile copy of the Letter of Transmittal and delivering
it, together with the certificate or certificates

                                       15
<PAGE>   16

representing the Initial Notes being tendered, if any, and any required
signature guarantees, to the Exchange Agent at its address set forth below on or
prior to 5:00 p.m., New York City time, on the expiration date, or complying
with the procedure for book-entry transfer described below, or (2) complying
with the guaranteed delivery procedures described below.

The method of delivery of Initial Notes, Letters of Transmittal and all other
required documents is at your election and risk and the delivery will be deemed
made only when actually received by the Exchange Agent. If such delivery is by
mail, we recommend that registered mail properly insured, with return receipt
requested, or an overnight or hand delivery service, be used. In all cases,
sufficient time should be allowed to insure timely delivery. No Initial Notes or
Letters of Transmittal should be sent to us.

Signatures on a Letter of Transmittal or a notice of withdrawal, as the case may
be, must be guaranteed unless the Initial Notes surrendered for exchange
pursuant thereto are tendered (1) by a registered holder of the Initial Notes
who has not completed the box entitled "Specific Issuance Instructions" or
"Special Delivery Instructions" on the Letter of Transmittal, or (2) for the
account of an Eligible Institution as defined herein. In the event that
signatures on a Letter of Transmittal or a notice of withdrawal, as the case may
be, are required to be guaranteed, such guarantee must be by a participant in a
recognized signature guaranty medallion program (each an "Eligible Institute").
If Initial Notes are registered in the name of a person other than a signer of
the Letter of Transmittal, the Initial Notes surrendered for exchange must be
endorsed by, or be accompanied by a written instrument or instruments of
transfer or exchange, in satisfactory form as determined by us in our sole
discretion, duly executed by the registered holder with the signature thereof
guaranteed by an Eligible Institution.

The Exchange Agent will make a request promptly after the date of this
Prospectus to establish accounts with respect to the Initial Notes at the
book-entry transfer facility, The Depository Trust Company, for the purposes of
facilitating the Exchange Offer, and subject to the establishment thereof, any
financial institution that is a participant in the book-entry transfer
facility's system may make book-entry delivery of Initial Notes by causing such
book-entry transfer facility to transfer such Initial Notes into the Exchange
Agent's account with respect to the Initial Notes in accordance with the
book-entry transfer facility's procedures for such transfer. Although delivery
of Initial Notes may be effected through book-entry transfer in the Exchange
Agent's account at the book-entry transfer facility, an appropriate Letter of
Transmittal with any required signature guarantee and other required documents
must in each case be transmitted to and received or confirmed by the Exchange
Agent at its address set forth below on or prior to the Expiration Date, or, if
the guaranteed delivery procedures described below are complied with, within the
time period provided under such procedures.

If you desire to accept the Exchange Offer and time will not permit a Letter of
Transmittal or Initial Notes to reach the Exchange Agent on or prior to the
Expiration Date or the procedure for book-entry transfer cannot be completed on
a timely basis, you may effect an exchange if the Exchange Agent has received at
its address or facsimile number set forth below on or prior to the Expiration
Date a letter, telegram or facsimile from an Eligible Institution setting forth
your name and address, the name in which the Initial Notes are registered and,
if possible, the certificate number or numbers of the certificate or
certificates representing the Initial Notes to be tendered, and stating that the
tender is being made thereby and guaranteeing that within three business days
after the Expiration Date the Initial Notes in proper form for transfer, or a
confirmation of book-entry transfer of such Initial Notes into the Exchange
Agent's account at the book-entry transfer facility, will be delivered by such
Eligible Institution together with a properly completed and duly executed Letter
of Transmittal and any other required documents. Unless Initial Notes being
tendered by the above-described method are deposited with the Exchange Agent
within the time period set forth above, accompanied or preceded by a properly
completed Letter of Transmittal and any other required documents, we may, at our
option, reject the tender. You may obtain copies of a Notice of Guaranteed
Delivery which may be used by an Eligible Institution for the purposes described
in this paragraph from the Exchange Agent.

Your tender will be deemed to have been received as of the date when (1) your
properly completed and duly signed Letter of Transmittal accompanied by the
Initial Notes, or a confirmation of book-entry

                                       16
<PAGE>   17

transfer of such the Initial Notes into the Exchange Agent's account at the
book-entry transfer facility, is received by the Exchange Agent, or (2) a Notice
of Guaranteed Delivery or letter, telegram or facsimile to similar effect (as
provided above) from an Eligible Institution is received by the Exchange Agent.
Issuance of Exchange Notes in exchange for Initial Notes tendered pursuant to a
Notice of Guaranteed Delivery or letter, telegram or facsimile to similar effect
by an Eligible Institution will be made only against deposit of the Letter of
Transmittal and any other required documents and the tendered Initial Notes.

All questions as to the validity, form, eligibility, time of receipt and
acceptance of Initial Notes tendered for exchange will be determined by us in
our sole discretion, which determination will be final and binding on all
parties. We reserve the right to reject any and all tenders of any particular
Initial Notes not properly tendered or reject any particular shares of Initial
Notes the acceptance of which might, in our judgment, be unlawful. We also
reserve the absolute right to waive any defects or irregularities or condition
of the Exchange Offer as to any particular Initial Notes either before or after
the Expiration Date, including the right to waive the ineligibility of any
holder who seeks to tender Initial Notes in the Exchange Offer. The
interpretation of the terms and conditions of the Exchange Offer, including the
Letter of Transmittal and the instructions thereto, by us shall be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Initial Notes for exchange must be cured within such
time as we shall determine. Neither we nor any other person shall be under any
duty to give notification of defects or irregularities with respect to tenders
of Initial Notes for exchange, nor shall any of them incur any liability for
failure to give such notification.

If the Letter of Transmittal or any Initial Notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and unless waived by us,
proper evidence satisfactory to us of their authority to so act must be
submitted.

If you are not a broker-dealer or are a broker-dealer but are not receiving
Exchange Notes for your own account, by tendering you will represent to us that,
among other things, the Exchange Notes acquired pursuant to the Exchange Offer
are being obtained in the ordinary course of your business, that you are not
engaged in, and do not intend to engage in, and have no arrangement or
understanding with any person to participate in the distribution of such
Exchange Notes and you are not an "affiliate" of Litton as defined in Rule 405
under the Securities Act of 1933 or, if you are an affiliate, you will comply
with the registration and prospectus delivery requirements of the Securities Act
of 1933, to the extent applicable. Each broker-dealer that is receiving Exchange
Notes for its own account in exchange for Initial Notes that were acquired as a
result of market-making or other trading activities will represent to us that it
will deliver a prospectus in connection with any resale of such Initial Notes.

In addition, we reserve the right in our sole discretion to (1) purchase or make
offers for any Initial Notes that remain outstanding subsequent to the
expiration date, or, as set forth under "Certain Conditions to the Exchange
Offer", to terminate the Exchange Offer and (2) to the extent permitted by
applicable law, purchase Initial Notes in the open market, in privately
negotiated transactions or otherwise. The terms of any such purchases or offers
may differ from the terms of the Exchange Offer.

WITHDRAWAL RIGHTS

You may withdraw tenders of Initial Notes at any time prior to 5:00 p.m., New
York City time, on the business day prior to the expiration date. For a
withdrawal to be effective, a written notice of withdrawal sent by letter,
telegram or facsimile must be received by the Exchange Agent at any time prior
to 5:00 p.m., New York City time, on the business day prior to the expiration
date at its address or facsimile a number set forth below. Any such notice of
withdrawal must (i) specify the name of the person having tendered the Initial
Notes to be withdrawn (the "Depositor"), the name in which the Initial Notes are
registered or, if tendered by book-entry transfer, the name of the Participant,
listing as the owner of such Initial Notes, if different from that of the
Depositor, (ii) identify the Initial Notes to be withdrawn, including the
certificate number of numbers of the certificates representing such Initial
Notes and the

                                       17
<PAGE>   18

aggregate principal amount of such Initial Notes, (iii) be signed by the holder
in the same manner as the original signature on the Letter of Transmittal by
which such Initial Notes were tendered, including any required signature
guarantees, or be accompanied by documents of transfer sufficient to permit the
Transfer Agent with respect to the Initial Notes to register the transfer of
such Initial Notes into the name of the person withdrawing the tender and (iv)
specify the name in which any such Initial Notes are to be registered, if
different from that of the Depositor. All questions as to the validity, form and
eligibility, including time of receipt, of such withdrawal notice will be
determined by us in our sole discretion, which determination will be final and
binding on all parties. Any Initial Notes so withdrawn will be deemed not to
have been validly tendered for purposes of the Exchange Offer and no Exchange
Notes will be issued with respect thereto unless the Initial notes so withdrawn
are validly retendered. Any Initial Notes which have been tendered but which are
withdrawn will be returned to the holder thereof without cost to such holder as
soon as practicable after such withdrawal. Properly withdrawn Initial Notes may
be retendered by following one of the procedures described above under
"Procedures for Tendering Initial Notes" at any time prior to the Expiration
Date.

ACCEPTANCE OF INITIAL NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES

Upon satisfaction or waiver of all of the conditions to the Exchange Offer we
will accept, promptly after the Expiration Date, all Initial Notes properly
tendered and will issue the Exchange Notes. See "Certain Conditions to the
Exchange Offer" below. For purposes of the Exchange Offer, we will be deemed to
have accepted properly tendered Initial Notes for exchange when we have given
oral or written notice thereof to the Exchange Agent.

In all cases, issuance of the Exchange Notes in exchange for Initial Notes
pursuant to the Exchange Offer will be made only after timely receipt by us of
such Initial Notes, a properly completed and duly executed Letter of Transmittal
and all other required documents. If any tendered Initial Notes are not accepted
for exchange for any reason set forth in the terms and conditions of the
Exchange Offer, such unaccepted Initial Notes will be returned without expense
to the tendering holder thereof as promptly as practicable after the rejection
of such tender or the expiration or termination of the Exchange Offer.

UNTENDERED INITIAL NOTES

Holders of Initial Notes whose Initial Notes are not tendered or are tendered
but not accepted in the Exchange Offer will continue to hold such Initial Notes
and will be entitled to all the rights and preferences and subject to the
limitations applicable thereto. Following consummation of the Exchange Offer,
the holders of Initial Notes will continue to be subject to the existing
restrictions upon transfer thereof and, except as provided in the Registration
Rights Agreement mentioned above, we will have no further obligation to such
holders to provide for the registration under the Securities Act of 1933 of the
Initial Notes held by them. To the extent that Initial Notes are tendered and
accepted in the Exchange Offer, the trading market for untendered and tendered
but unaccepted Initial Notes could be adversely affected.

CERTAIN CONDITIONS TO THE EXCHANGE OFFER

Notwithstanding any other term of the Exchange Offer, we will not be required to
accept for exchange, or issue Exchange Notes in exchange for, any Initial Notes,
and may terminate or amend the Exchange Offer, if at any time before the
acceptance of such Initial Notes for exchange, any of the following events shall
occur:

(1) an injunction, order or decree shall have been issued by any court or
    governmental agency that would prohibit, prevent or otherwise materially
    impair our ability to proceed with the Exchange Offer; or

(2) there shall occur a change in the current interpretation of the staff of the
    Commission which current interpretation permits the Exchange Notes issued
    pursuant to the Exchange Offer in exchange for the Initial Notes to be
    offered for resale, resold and otherwise transferred by holders thereof,
    other than by (1) a broker-dealer who purchases such Exchange Notes directly
    from Litton to resell pursuant to
                                       18
<PAGE>   19

    Rule 144A, Regulation S or any other available exemption under the
    Securities Act of 1933 or (2) a person that is an affiliate of Litton within
    the meaning of Rule 405 under the Securities Act of 1933, without compliance
    with the registration and prospectus delivery provisions of the Securities
    Act of 1933 provided that such Exchange Notes are acquired in the ordinary
    course of such holders' business and such holders have no arrangement with
    any person to participate in the distribution of Exchange Notes.

The foregoing conditions are for our sole benefit and may be asserted by us
regardless of the circumstances giving rise to any such condition or may be
waived by us in whole or in part at any time and from time to time in our sole
discretion. The failure by us at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right and each such right shall
be deemed on going right which may be asserted by us at any time and from time
to time.

If we determine that we may terminate the Exchange Offer, as set forth above, we
may (1) refuse to accept any Initial Notes and return any Initial Notes that
have been tendered to their holders, (2) extend the Exchange Offer and retain
all Initial Notes tendered prior to the expiration date, subject to the rights
of such holders of tendered shares of Initial Notes to withdraw their tendered
Initial Notes, or (3) waive such termination event with respect to the Exchange
Offer and accept all properly tendered Initial Notes that have not been
withdrawn. If such waiver constitutes a material change in the Exchange Offer,
we will disclose such change by means of a supplement to this Prospectus that
will be distributed to each registered holder of Initial Notes, and we will
extend the Exchange Offer for a period of five to ten business days, depending
upon the significance of the waiver and the manner of disclosure to the
registered holders of the Initial Notes, if the Exchange Offer would otherwise
expire during such period.

In addition, we will not accept for exchange any Initial Notes tendered, and no
Exchange Notes will be issued in exchange for any such Initial Notes, if at any
time any stop order shall be threatened by the SEC or in effect with respect to
the Registration Statement.

The Exchange Offer is not conditioned on any minimum principal amount of Initial
Notes being tendered for exchange.

Exchange Notes.

SOLICITATION OF TENDERS, FEES AND EXPENSES

We have not retained any dealer-manager in connection with the Exchange Offer
and will not make any payments to brokers, dealers or other persons soliciting
acceptance of the Exchange Offer. We will, however, pay the Exchange Agent
reasonable and customary fees for its services and will reimburse the

                                       19
<PAGE>   20

Exchange Agent for its reasonable out-of-pocket expenses in connection
therewith. The cash expenses to be incurred by us in connection with the
Exchange Offer will be paid by us.

No person has been authorized to give any information or to make any
representation in connection with the Exchange Offer other than those contained
in this Prospectus. If given or made, such information or representations should
not be relied upon as having been authorized by us. Neither the delivery of this
Prospectus nor any exchange made hereunder shall, under any circumstances,
create any implication that there has been no change in our affairs since the
respective dates as of which information is given. We are not seeking tenders of
Initial Notes from or on behalf of holders of Initial Notes in any jurisdiction
in which the making of the Exchange Offer or the acceptance of Initial Notes
would not be in compliance with the laws of such jurisdiction.

TRANSFER TAXES

We will pay all transfer taxes, if any, applicable to the exchange of Initial
Notes pursuant to the Exchange Offer. If, however, certificates representing
Exchange Notes or Initial Notes not tendered or accepted for exchange are to be
delivered to, or are to be registered or issued in the name of, any person other
than the registered holder of the Initial Notes tendered, or if tendered Initial
Notes are registered in the name of any person other than the person signing the
Letter of Transmittal, or if a transfer tax is imposed for any reason other than
the exchange of Exchange Notes pursuant to the Exchange Offer, then the amount
of any transfer taxes, whether imposed on the registered holder or any other
persons, will be payable by the tendering holder. If satisfactory evidence of
payment of or exemption from transfer taxes is not submitted with the Letter of
Transmittal, the amount of transfer taxes will be billed directly to the
tendering holders.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following summary is based on the Internal Revenue Code of 1986, as amended
(the "Code"), its legislative history, existing and proposed regulations
thereunder, published rulings and court decisions, all as currently in effect
and all subject to change at any time, perhaps with retroactive effect.

If you are considering exchanging your Initial Notes for Exchange Notes you
should consult your own tax advisor concerning the consequences, in your
particular circumstances, under the Code and the laws of any other taxing
jurisdiction, of such exchange.

This discussion is not intended to deal with all aspects of U.S. federal income
taxation that might be relevant to you in light of your investment or tax
circumstances or status, nor does it discuss the U.S. federal income tax
consequences to you if you are subject to special treatment under the U.S.
federal income tax laws, such as if you are a certain type of financial
institution, insurance company, dealer in securities or foreign currency, a
tax-exempt organization, a foreign corporation or a nonresident alien
individual, or if you are holding Initial Notes or Exchange Notes as a hedge
against, or that are hedged against, currency risk or that are part of a
straddle or conversion transaction, or if your functional currency is not the
United States dollar. Moreover, the effect of any state, local or foreign tax
laws is not discussed.

THE FOLLOWING DISCUSSION IS FOR GENERAL INFORMATION ONLY. IF YOU ARE A HOLDER OF
AN INITIAL NOTE THAT IS PARTICIPATING IN THE EXCHANGE OFFER YOU ARE STRONGLY
URGED TO CONSULT WITH YOUR OWN TAX ADVISORS TO DETERMINE THE IMPACT OF YOUR
PARTICULAR TAX SITUATION ON THE ANTICIPATED TAX CONSEQUENCES, INCLUDING THE TAX
CONSEQUENCES UNDER STATE, LOCAL, FOREIGN OR OTHER TAX LAWS, OF THE EXCHANGE OF
THE INITIAL NOTES FOR THE EXCHANGE NOTES UNDER THE EXCHANGE OFFER.

EXCHANGE OFFER

The exchange of the Initial Notes by you for the Exchange Notes should not be
treated as an "exchange" for federal income tax purposes because the Exchange
Notes should not be considered to differ materially from the Initial Notes. The
Exchange Notes received by you should be treated as a continuation of the
Initial Notes. As a result, there should be no federal income tax consequences
to you for exchanging the Initial Notes for the Exchange Notes and the federal
income tax consequences of holding and disposing of the Exchange Notes should be
the same as the federal income tax consequences of holding and disposing of the
Initial Notes. Accordingly, your adjusted tax basis in the Exchange Notes will
be the same as your adjusted tax basis in the Initial Notes and your holding
period for the Initial Notes will be included in your holding period for the
Exchange Notes. Thus, the determination of gain on a sale or other disposition
of the Exchange Notes will be the same as for the Initial Notes.

ACCOUNTING TREATMENT

No gain or loss for accounting purposes will be recognized by us upon the
consummation of the Exchange Offer.

                              PLAN OF DISTRIBUTION

Based on no-action letters issued by the staff of the SEC to third parties, we
believe that the Exchange Notes issued pursuant to the Exchange Offer in
exchange for Initial Notes may be offered for resale, resold and otherwise
transferred by holders thereof other than (1) a broker-dealer who purchases such
Exchange Notes directly from us to resell pursuant to Rule 144A or any other
available exemption under the Securities Act of 1933 or (2) a person that is an
affiliate of ours within the meaning of Rule 405 under the Securities Act of
1933, without compliance with the registration and prospectus delivery
requirements of the Securities Act of 1933 provided that Exchange Notes are
acquired in the ordinary course of such holders' business and such holders have
no arrangement with any person to participate in the distribution of such
Exchange Notes. Any holder of Initial Notes who tenders in the Exchange Offer
                                       21
<PAGE>   22

for the purpose of participating in a distribution of the Exchange Notes could
not rely on such interpretation by the staff of the SEC and must comply with the
registration and prospectus delivery requirements of the Securities Act of 1933
in connection with any resale transaction. Thus, any Exchange Notes acquired by
such holders will not be freely transferable except in compliance with the
Securities Act of 1933.

Each broker-dealer that receives Exchange Notes for its own account in exchange
for Initial Notes acquired as a result of market-making or other trading
activities must acknowledge that it will deliver a prospectus in connection with
any resale of such Exchange Notes. For a period of 90 days after the Expiration
Date, this Prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of such Exchange
Notes. During such 90-day period, we will use our reasonable best efforts to
make this Prospectus available to any broker-dealer for use in connection with
such resale, provided that such broker-dealer indicates in the Letter of
Transmittal that it is a broker-dealer.

We will not receive any proceeds from any sale of Exchange Notes by
broker-dealers. Exchange Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the Exchange Notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through broker-dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells Exchange Notes that were received by it for its own
account pursuant to the Exchange Offer and any person that participates in the
distribution of such Exchange Notes may be deemed to be an "underwriter" within
the meaning of the Securities Act of 1933 and any profit on any such resale of
Exchange Notes and any commissions or concessions received by any such
broker-dealers may be deemed to be underwriting compensation under the
Securities Act of 1933. The Letter of Transmittal states that a broker-dealer,
by acknowledging that it will deliver and by delivering a prospectus, will not
be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act of 1933.

We will indemnify the holders of the Exchange Notes (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act of 1933.

                           VALIDITY OF EXCHANGE NOTES

The validity of the Exchange Notes will be passed upon for Litton by John E.
Preston, Esq., the Senior Vice President and General Counsel of Litton. As of
January 31, 2000, Mr. Preston beneficially owns 13,024 shares of common stock of
Litton, 1,777 nonvoting deferred stock units equal to 1,777 shares of common
stock of Litton, and has options to purchase 82,258 shares of common stock of
Litton.

                                    EXPERTS

The consolidated financial statements incorporated in this Prospectus by
reference from Litton's Annual Report on Form 10-K for the year ended July 31,
1999 have been audited by Deloitte & Touche LLP, independent auditors, as stated
in their report, which is incorporated herein by reference, and have been so
incorporated in reliance upon the report of such firm, given upon their
authority as experts in accounting and auditing.

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law provides that a corporation
shall have the power, and in some cases is required, to indemnify an agent,
including an officer or director, who was or is a party or is threatened to be
made a party to any proceedings, against certain expenses, judgments, fines,
settlements and other amounts under certain circumstances. Litton's Certificate
of Incorporation provides that Litton may indemnify its agents to the maximum
extent permitted under Delaware law, and maintains insurance covering certain
liabilities of the directors and officers of Litton and its subsidiaries.

ITEM 22. UNDERTAKINGS

A. The undersigned Registrant hereby undertakes:

          (1) to file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

             (a) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933;

             (b) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represents a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;

             (c) To include any material information with respect to the plan of
        distribution not previously disclosed in the registration statement of
        any material change to such information in the registration statement.

          (2) that, for the purposes of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof; and

          (3) to remove from registration by means of a post-effective amendment
     any of the securities being registered that remain unsold at the
     termination of the offering.

B. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bone fide offering thereof.

C. Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, and persons of the Registrant
pursuant to the foregoing provisions, or otherwise the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit of proceeding) is asserted by such
director, officer or controlling person in connection with the securities being

Delivery of this letter of transmittal to an address other than as set forth

the "Prospectus"), of Litton Industries, Inc., a Delaware corporation

YOU SHOULD READ THE INSTRUCTIONS CONTAINED HEREIN CAREFULLY BEFORE THIS LETTER
OF TRANSMITTAL IS COMPLETED.

Capitalized terms used but not defined herein shall have the same meaning given
them in the Prospectus.

Holders of Initial Notes must complete either this Letter of Transmittal or an

Facility" or "DTC") pursuant to the procedures set forth in "Exchange Offer" and
"Description of the Initial Notes and the Exchange Notes" in the Prospectus and

Ladies and Gentlemen:

Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to Litton the above described aggregate principal
amount of Litton's outstanding 8% Senior Notes Due 2009 (the "Initial Notes")
for the same aggregate principal amount of 8% Notes Due 2009 (the "Exchange
Notes") upon the terms and subject to the conditions set forth in the
Prospectus, receipt of which is acknowledged, and in this Letter of Transmittal
(which, together with the Prospectus, constitute the "Exchange Offer").

Subject to and effective upon the acceptance for exchange of all or any portion
of the Initial Notes tendered herewith in accordance with the terms and
conditions of the Exchange Offer (including, if the Exchange Offer is extended
or amended, the terms and conditions of any such extension or amendment), the
undersigned hereby sells, assigns and transfers to or upon the order of Litton
all right, title and interest in and to such Initial Notes as are being tendered
herewith. The undersigned hereby irrevocably constitutes and appoints the
Exchange Agent as its agent and attorney-in-fact (with full knowledge that the
Exchange Agent is also acting as agent of Litton in connection with the Exchange
Offer) with respect to the tendered Initial Notes, with full power of
substitution (such power of attorney being deemed to be an irrevocable power
coupled with an interest) subject only to the right of withdrawal described in
the Prospectus, to (i) deliver Certificates for Initial Notes to Litton together
with all accompanying evidences of transfer and authenticity to, or upon the
order of, Litton, upon receipt by the Exchange Agent, as the undersigned's
agent, of the Exchange Notes to be issued in exchange for such Initial Notes,
(ii) present Certificates for such Initial Notes for transfer, and to transfer
the Initial Notes on the books of Litton, and (iii) receive for the account of
Litton all benefits and otherwise exercise all rights of beneficial ownership of
such Initial Notes, all in accordance with the terms and conditions of the
Exchange Offer.

THE UNDERSIGNED HEREBY REPRESENTS AND WARRANTS THAT THE UNDERSIGNED HAS FULL
POWER AND AUTHORITY TO TENDER, EXCHANGE, SELL, ASSIGN AND TRANSFER THE INITIAL
NOTES TENDERED HEREBY AND THAT, WHEN THE SAME ARE ACCEPTED FOR EXCHANGE, LITTON
WILL ACQUIRE GOOD, MARKETABLE AND UNENCUMBERED TITLE THERETO, FREE AND CLEAR OF
ALL LIENS, RESTRICTIONS, CHARGES AND ENCUMBRANCES, AND THAT THE INITIAL NOTES
TENDERED HEREBY ARE NOT SUBJECT TO ANY ADVERSE CLAIMS OR PROXIES. THE
UNDERSIGNED WILL, UPON REQUEST, EXECUTE AND DELIVER ANY ADDITIONAL DOCUMENTS
DEEMED BY LITTON OR THE EXCHANGE AGENT TO BE NECESSARY OR DESIRABLE TO COMPLETE
THE EXCHANGE, ASSIGNMENT AND TRANSFER OF THE INITIAL NOTES TENDERED HEREBY, AND
THE UNDERSIGNED WILL COMPLY WITH ITS OBLIGATIONS UNDER THE REGISTRATION RIGHTS
AGREEMENT DATED AS OF OCTOBER 13, 1999, BETWEEN LITTON AND THE INITIAL
PURCHASERS OF THE INITIAL NOTES (THE "REGISTRATION RIGHTS AGREEMENT"). THE
UNDERSIGNED HAS READ AND AGREES TO ALL OF THE TERMS OF THE EXCHANGE OFFER.

The name(s) and address(es) of the registered holder(s) of the Initial Notes
tendered hereby should be printed above, if they are not already set forth
above, as they appear on the Certificates representing such Initial Notes. The
Certificate number(s) and the Initial Notes that the undersigned wishes to
tender should be indicated in the appropriate boxes above.

If any tendered Initial Notes are not exchanged pursuant to the Exchange Offer
for any reason, or if Certificates are submitted for more Initial Notes than are
tendered or accepted for exchange, Certificates for such nonexchanged or
nontendered Initial Notes will be returned (or, in the case of Initial Notes
tendered by book-entry transfer, such Initial Notes will be credited to an
account maintained at DTC), without expense to the tendering holder, promptly
following the expiration or termination of the Exchange Offer.

The undersigned understands that tenders of Initial Notes pursuant to any one of
the procedures described in "Exchange Offer" and "Description of the Initial
Notes and the Exchange Notes" in the Prospectus and in the instructions attached
hereto will, upon Litton's acceptance for exchange of such tendered Initial
Notes, constitute a binding agreement between the undersigned and Litton upon
the terms and subject to the conditions of the Exchange Offer. The undersigned
recognizes that, under certain circumstances set forth in the Prospectus, Litton
may not be required to accept for exchange any of the Initial Notes tendered
hereby.

Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, the undersigned hereby directs that the Initial Notes be
issued in the name(s) of the undersigned or, in the case of a book-entry
transfer of Initial Notes, that such Initial Notes be credited to the account
indicated above maintained at DTC. If applicable, substitute

transfer of Initial Notes, will be credited to the account indicated above

Instructions," please deliver Initial Notes to the undersigned at the address
shown below the undersigned's signature.

BY TENDERING INITIAL NOTES AND EXECUTING THIS LETTER OF TRANSMITTAL, THE
UNDERSIGNED HEREBY REPRESENTS AND AGREES THAT (I) THE UNDERSIGNED IS NOT AN
"AFFILIATE" OF LITTON, (II) ANY EXCHANGE NOTES TO BE RECEIVED BY THE UNDERSIGNED
ARE BEING ACQUIRED IN THE ORDINARY COURSE OF ITS BUSINESS, (III) THE UNDERSIGNED
IS NOT ENGAGED IN, AND DOES NOT INTEND TO ENGAGE IN, AND HAS NO ARRANGEMENT OR
UNDERSTANDING WITH ANY PERSON TO PARTICIPATE IN, A DISTRIBUTION (WITHIN THE
MEANING OF THE SECURITIES ACT) OF EXCHANGE NOTES TO BE RECEIVED IN THE EXCHANGE
OFFER. BY TENDERING INITIAL NOTES PURSUANT TO THE EXCHANGE OFFER AND EXECUTING
THIS LETTER OF TRANSMITTAL, A HOLDER OF INITIAL NOTES WHICH IS A BROKER-DEALER
REPRESENTS AND AGREES, CONSISTENT WITH CERTAIN INTERPRETIVE LETTERS ISSUED BY
THE STAFF OF THE DIVISION OF CORPORATION FINANCE OF THE SECURITIES AND EXCHANGE
COMMISSION TO THIRD PARTIES, THAT (A) SUCH INITIAL NOTES HELD BY THE BROKER-
DEALER ARE HELD ONLY AS A NOMINEE, OR (B) SUCH INITIAL NOTES WERE ACQUIRED BY
SUCH BROKER-DEALER FOR ITS OWN ACCOUNT AS A RESULT OF MARKET-MAKING ACTIVITIES
OR OTHER TRADING ACTIVITIES AND IT WILL DELIVER THE PROSPECTUS MEETING THE
REQUIREMENTS OF THE SECURITIES ACT IN CONNECTION WITH ANY RESALE OF SUCH
EXCHANGE NOTES (PROVIDED THAT, BY SO ACKNOWLEDGING AND BY DELIVERING A
PROSPECTUS, SUCH BROKER-DEALER MAY NOT BE DEEMED TO BE AN "UNDERWRITER" WITHIN
THE MEANING OF THE SECURITIES ACT). LITTON HAS AGREED THAT, SUBJECT TO THE
PROVISIONS OF THE REGISTRATION RIGHTS AGREEMENT, THE PROSPECTUS, AS IT MAY BE
AMENDED OR SUPPLEMENTED FROM TIME TO TIME, MAY BE USED BY A PARTICIPATING
BROKER-DEALER (AS DEFINED BELOW) IN CONNECTION WITH RESALES OF EXCHANGE NOTES
RECEIVED IN EXCHANGE FOR INITIAL NOTES, WHERE SUCH INITIAL NOTES WERE ACQUIRED
BY SUCH PARTICIPATING BROKER-DEALER FOR ITS OWN ACCOUNT AS A RESULT OF MARKET-
MAKING ACTIVITIES OR OTHER TRADING ACTIVITIES, FOR A PERIOD ENDING 90 DAYS AFTER
THE EXCHANGE OFFER REGISTRATION STATEMENT IS DECLARED EFFECTIVE (SUBJECT TO
EXTENSION UNDER CERTAIN LIMITED CIRCUMSTANCES DESCRIBED IN THE PROSPECTUS) OR,
IF EARLIER, WHEN ALL SUCH EXCHANGE NOTES HAVE BEEN DISPOSED OF BY SUCH
PARTICIPATING BROKER-DEALER. IN THAT REGARD, EACH BROKER-DEALER WHO ACQUIRED
INITIAL NOTES FOR ITS OWN ACCOUNT AS A RESULT OF MARKET-MAKING OR OTHER TRADING
ACTIVITIES (A "PARTICIPATING BROKER-DEALER"), BY TENDERING SUCH INITIAL NOTES
AND EXECUTING THIS LETTER OF TRANSMITTAL, AGREES THAT, UPON RECEIPT OF NOTICE
FROM LITTON OF THE OCCURRENCE OF ANY EVENT OR THE DISCOVERY OF ANY FACT WHICH
MAKES ANY STATEMENT CONTAINED OR INCORPORATED BY REFERENCE IN THE PROSPECTUS
UNTRUE IN ANY MATERIAL RESPECT OR THAT REQUIRES THE MAKING OF ANY ADDITIONS TO
OR CHANGES IN THE PROSPECTUS IN ORDER TO MAKE THE STATEMENTS CONTAINED OR
INCORPORATED BY REFERENCE THEREIN, IN LIGHT OF THE CIRCUMSTANCES UNDER WHICH
THEY WERE MADE, NOT MISLEADING OR OF THE OCCURRENCE OF CERTAIN OTHER EVENTS
SPECIFIED IN THE REGISTRATION RIGHTS AGREEMENT, SUCH PARTICIPATING BROKER-DEALER
WILL SUSPEND THE SALE OF EXCHANGE NOTES PURSUANT TO THE PROSPECTUS UNTIL LITTON
HAS AMENDED OR SUPPLEMENTED THE PROSPECTUS TO CORRECT SUCH MISSTATEMENT OR
OMISSION AND HAS FURNISHED COPIES OF THE AMENDED OR SUPPLEMENTED PROSPECTUS TO
THE PARTICIPATING BROKER-DEALER OR LITTON HAS GIVEN NOTICE THAT THE SALE OF THE
EXCHANGE NOTES MAY BE RESUMED, AS THE CASE MAY BE. IF LITTON GIVES SUCH NOTICE
TO SUSPEND THE SALE OF THE EXCHANGE NOTES, IT SHALL EXTEND THE 90-DAY PERIOD
REFERRED TO ABOVE DURING WHICH PARTICIPATING BROKER DEALERS ARE ENTITLED TO USE
THE PROSPECTUS IN CONNECTION WITH THE RESALE OF EXCHANGE NOTES BY THE NUMBER OF
DAYS DURING THE PERIOD FROM AND INCLUDING THE DATE OF THE GIVING OF SUCH

                                        5
<PAGE>   6

NOTICE TO AND INCLUDING THE DATE WHEN PARTICIPATING BROKER-DEALERS SHALL HAVE
RECEIVED COPIES OF THE SUPPLEMENTED OR AMENDED PROSPECTUS NECESSARY TO PERMIT
RESALES OF THE EXCHANGE NOTES OR TO AND INCLUDING THE DATE ON WHICH LITTON HAS
GIVEN NOTICE THAT THE SALE OF EXCHANGE NOTES MAY BE RESUMED, AS THE CASE MAY BE.

Holders of Initial Notes whose Initial Notes are accepted for exchange will not
receive accrued interest on such Initial Notes for any period from and after the
last Interest Payment Date to which interest has been paid or duly provided for
on such Initial Notes prior to the original issue date of the Exchange Notes or,
if no such interest has been paid or duly provided for, will not receive any
accrued interest on such Initial Notes, and the undersigned waives the right to
receive any interest on such Initial Notes accrued from and after such Interest
Payment Date or, if no such interest has been paid or duly provided for, from
and after October 18, 1999.

The undersigned will, upon request, execute and deliver any additional documents
deemed by Litton to be necessary or desirable to complete the sale, assignment
and transfer of the Initial Notes tendered hereby. All authority herein
conferred or agreed to be conferred in this Letter of Transmittal shall survive
the death or incapacity of the undersigned and any obligation of the undersigned
hereunder shall be binding upon the heirs, executors, administrators, personal
representatives, trustees in bankruptcy, legal representatives, successors and
assigns of the undersigned. Except as stated in the Prospectus, this tender is
irrevocable.

     THE UNDERSIGNED, BY COMPLETING THE BOX ENTITLED "DESCRIPTION OF INITIAL
NOTES" ABOVE AND SIGNING THIS LETTER, WILL BE DEEMED TO HAVE TENDERED THE
INITIAL NOTES AS SET FORTH IN SUCH BOX.

  INSTRUCTIONS FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

1. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED DELIVERY
PROCEDURES.

          (A) If the holder is tendering Certificates, such holder must deliver
     (i) the Certificate(s) representing the Initial Notes tendered, (ii) a
     properly completed and duly executed copy of this Letter of Transmittal and
     (iii) any other documents required by this letter of transmittal, all of
     which must be received by the Exchange Agent at its address set forth
     herein prior to the Expiration Date.

          (B) If the holder is tendering Initial Notes by book-entry transfer,
     such holder must (i) utilize DTC's ATOP system to tender such holder's
     Initial Notes, to an account established at DTC by the Exchange Agent, (ii)
     make the Agent's Message and cause a timely confirmation of a book-entry
     transfer (a "Book-Entry Confirmation") to be issued to the Exchange Agent
     or deliver a properly completed and duly executed copy of this Letter of
     Transmittal and (iii) deliver any other documents required by this Letter
     of Transmittal, all of which must be received by the Exchange Agent at its
     DTC account or address set forth herein prior to the Expiration Date.

The method of delivery of certificates for Initial Notes and all other required
documents is at the election and risk of the tendering holder and delivery will
be deemed made only when actually received by the Exchange Agent. If delivery is
by mail, registered mail with return receipt requested, properly insured, is
recommended. Instead of delivery by mail it is recommended that the holder use
an overnight or hand delivery service. In all cases, sufficient time should be
allowed to assure timely delivery. In no event should any Initial Notes or
documentation be sent to Litton. Neither Litton nor the registrar is under any
obligation to notify any tendering holder of Litton's acceptance of tendered
Initial Notes prior to the Expiration Date.

This Letter of Transmittal is to be completed either if (a) Certificates are to
be forwarded herewith or (b) tenders are to be made pursuant to the procedures
for tender by book-entry transfer set forth in "Exchange Offer" and "Description
of the Initial Notes and the Exchange Notes" in the Prospectus. Certificates, or
timely confirmation of a book-entry transfer of such Initial Notes into the
Exchange Agent's account at DTC, as well as this Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, and any other documents required by this Letter of
Transmittal (or electronic acknowledgment and agreement thereto in the case of
exchanges made through DTC's ATOP system), must be received by the Exchange
Agent at its address set forth herein on or prior to the Expiration Date.
Initial Notes may be tendered in whole or in part in the principal amount of
$1,000 and integral multiples of $1,000 in excess thereof, provided that, if any
Initial Notes are tendered for exchange in part, the untendered principal amount
thereof must be $1,000 or an integral multiple of $1,000 in excess thereof.

Holders who wish to tender their Initial Notes and (i) whose Initial Notes are
not immediately available or (ii) who cannot deliver their Initial Notes, this
Letter of Transmittal and all other required documents to the Exchange Agent on
or prior to the Expiration Date or (iii) who cannot complete the procedures for
delivery by book-entry transfer on a timely basis, may tender their Initial
Notes by properly completing and duly executing a Notice of Guaranteed Delivery
pursuant to the guaranteed delivery procedures set forth in "Exchange Offer" in
the Prospectus. Pursuant to such procedures: (i) such tender must be made by or
through an Eligible Institution (as defined below); (ii) a properly completed
and duly executed Notice of Guaranteed Delivery, substantially in the form made
available by Litton, must be received by the Exchange Agent on or prior to the
Expiration Date; and (iii) the Certificates (or a Book-Entry Confirmation)
representing all tendered Initial Notes, in proper form for transfer, together
with a Letter of Transmittal (or facsimile thereof) or a properly transmitted
Agent's Message, properly completed and duly executed, with any required
signature guarantees and any other documents required by this Letter of
Transmittal, must be received by the Exchange Agent within three business days
after the date of execution of such Notice of Guaranteed Delivery, all as
provided in "Exchange Offer" in the Prospectus.

The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
facsimile or mail to the Exchange Agent, and must include a guarantee by an
Eligible Institution in the form set forth in such notice. For Initial Notes to
be properly tendered pursuant to the guaranteed delivery procedure, the Exchange
Agent must receive a Notice of Guaranteed Delivery on or prior to the Expiration
Date. As used herein and in the Prospectus, "Eligible Institution" means a firm
or other entity identified in Rule 17Ad-15 under the Exchange Act as "an
eligible guarantor institution," including (as such terms are defined therein)
(i) a bank; (ii) a broker, dealer, municipal securities broker or dealer or
government securities broker or dealer; (iii) a credit union; (iv) a national
securities exchange, registered securities association or clearing agency; or
(v) a savings association (as that term is defined in Section 3(b) of the
Federal Deposit Insurance Act).

THE METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE TENDERING HOLDER AND THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE
                                        9
<PAGE>   10

AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED,
PROPERLY INSURED, OR OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN ALL CASES
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY. NO INITIAL NOTES OR
LETTERS OF TRANSMITTAL SHOULD BE SENT TO LITTON.

Litton will not accept any alternative, conditional or contingent tenders. Each
tendering holder, by execution of a Letter of Transmittal (or facsimile
thereof), waives any right to receive any notice of the acceptance of such
tender.

2. GUARANTEE OF SIGNATURES. No signature guarantee on this Letter of Transmittal
is required if:

          (i) this Letter of Transmittal is signed by the registered holder
     (which term, for purposes of this document, shall include any participant
     in DTC whose name appears on the register of holders maintained by Litton
     as the owner of the Initial Notes) of Initial Notes tendered herewith,
     unless such holder(s) has completed either the box entitled "Special
     Issuance Instructions" or the box entitled "Special Delivery Instructions"
     above, or

          (ii) such Initial Notes are tendered for the account of a firm that is
               an Eligible Institution.

In all other cases, an Eligible Institution must guarantee the signatures on
this Letter of Transmittal. See Instruction 5.

3. INADEQUATE SPACE. If the space provided in the box captioned "Description of
Initial Notes" is inadequate, the Certificate number(s) and/or the principal
amount of Initial Notes and any other required information should be listed on a
separate signed schedule and attached to this Letter of Transmittal.

4. PARTIAL TENDERS AND WITHDRAWAL RIGHTS. Tenders of Initial Notes will be
accepted only in the principal amount of $1,000 and integral multiples of $1,000
in excess thereof, provided that if any Initial Notes are tendered for exchange
in part, the untendered principal amount thereof must be $1,000 or an integral
multiple of $1,000 in excess thereof. If less than all the Initial Notes
evidenced by any Certificate submitted are to be tendered, fill in the principal
amount of Initial Notes which are to be tendered in the box entitled "Principal
Amount of Initial Notes Tendered (if less than all)." In such case, new
Certificate(s) for the remainder of the Initial Notes that were evidenced by
your old Certificate(s) will only be sent to the holder of the existing
security, promptly after the Expiration Date. All Initial Notes represented by
Certificates delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.

Except as otherwise provided herein, tenders of Initial Notes may be withdrawn
at any time on or prior to 5:00 p.m., New York City time, on the business day
prior to the Expiration Date. In order for a withdrawal to be effective on or
prior to that time, a written, telegraphic, telex or facsimile transmission of
such notice of withdrawal must be timely received by the Exchange Agent at one
of its addresses set forth above or in the Prospectus no later than 5:00 P.M. of
the business day prior to the Expiration Date. Any such notice of withdrawal
must (i) specify the name of the person having tendered the Initial Notes to be
withdrawn (the "Depositor") the name in which the Initial Notes are registered
(or, if tendered by book-entry transfer, the name of the participant in DTC
whose name appears on a security participant listing as the owner of such
Initial Notes) if different from that of the Depositor, (ii) identify the
Initial Notes to be withdrawn (including the certificate number or numbers of
the certificate or certificates representing such Initial Notes and the
aggregate principal amount of such Initial Notes), (iii) be signed by the holder
in the same manner as the original signature on the Letter of Transmittal by
which such Initial Notes were tendered (including any required signature
guarantees) or be accompanied by documents of transfer sufficient to permit the
Transfer Agent of such Initial Notes to register the transfer of such Initial
Notes into the name of the person withdrawing the tender and (iv) specify the
name in which any such Initial Notes are to be registered, if different from the
Depositor. If Initial Notes have been tendered pursuant to the procedures for
book-entry, transfer set forth in the Prospectus under "Exchange Offer" and
"Description of the Initial Notes and the Exchange Notes," the notice of
withdrawal must specify the name and number of the account at DTC to be credited
with the withdrawal of Initial Notes, in which case a notice of withdrawal will
be effective if delivered to the Exchange Agent by written, telegraphic, telex
or facsimile transmission. Withdrawals of tenders of Initial Notes may not be
rescinded. Initial Notes properly withdrawn will not be deemed validly tendered
for purposes of the Exchange Offer, but may be retendered at any subsequent time
on or prior to the Expiration Date by following any of the procedures described
in the Prospectus under "Exchange Offer" and "Description of the Initial Notes
and the Exchange Notes."

All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by Litton, in its sole
discretion, whose determination shall be final and binding on all parties. None
of Litton, any affiliates or assigns of Litton, the Exchange Agent or any other
person shall be under any duty to give any notification of any irregularities in
any notice of withdrawal or incur any liability for failure to give any such
notification. Any Initial Notes which have been tendered but which are withdrawn
will be returned to the holder thereof without cost to such holder promptly
after withdrawal.

5. SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS. If this
Letter of Transmittal is signed by the registered holder(s) of the Initial Notes
tendered hereby, the signature(s) must correspond exactly with the name(s) as
written on the face of the Certificate(s) without alteration, enlargement or any
change whatsoever.

If any of the Initial Notes tendered hereby are owned of record by two or more

trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary, or representative capacity, such
persons should so indicate when signing and must submit proper evidence
satisfactory, to Litton, in its sole discretion, of each such person's authority
so to act.

When this Letter of Transmittal is signed by the registered owner(s) of the
Initial Notes listed and transmitted hereby, no endorsement(s) of Certificate(s)
or separate bond power(s) are required unless Exchange Notes are to be issued in
the name of a person other than the registered holder(s). Signature(s) on such
Certificate(s) or bond power(s) must be guaranteed by an Eligible Institution.

If this Letter of Transmittal is signed by a person other than the registered
owner(s) of the Initial Notes listed, the Certificates must be endorsed or
accompanied by appropriate bond powers, signed exactly as the name or names of
the registered owner(s) appear(s) on the Certificates, and also must be
accompanied by such opinions of counsel, certifications and other information as
Litton or the Trustee for the Initial Notes may require in accordance with the
restrictions on transfer applicable to the Initial Notes. Signatures on such
Certificates or bond powers must be guaranteed by an Eligible Institution.

6. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. If Exchange Notes are to be
issued in the name of a person other than the signer of this Letter of
Transmittal, or if Exchange Notes are to be sent to someone other than the
signer of this Letter of Transmittal or to an address other than that shown
above, the appropriate boxes on this Letter of Transmittal should be completed.
Certificates for Initial Notes not exchanged will be returned by mail or, if
tendered by book-entry transfer, by crediting the account indicated above
maintained at DTC. See Instruction 4.

7. IRREGULARITIES. Litton will determine, in its sole discretion, all questions
as to the form of documents, validity, eligibility (including time of receipt)
and acceptance for exchange of any tender of Initial Notes, which determination
shall be final and binding on all parties. Litton reserves the absolute right to
reject any and all tenders that it determines are not in proper form or the
acceptance of which, or exchange for which, may, in the view of counsel to
Litton, be unlawful. Litton also reserves the absolute right, subject to
applicable law, to waive any of the conditions of the Exchange Offer set forth
in the Prospectus under "Exchange Offer" and "Description of the Initial Notes
and the Exchange Notes" or any conditions or irregularity in any tender of
Initial Notes of any particular holder whether or not similar conditions or
irregularities are waived in the case of other holders. Litton's interpretation
of the terms and conditions of the Exchange Offer (including this Letter of
Transmittal and the instructions hereto) will be final and binding. No tender of
Initial Notes, will be deemed to have been validly made until all irregularities
with respect to such tender have been cured or waived. Neither Litton, any
affiliates or assigns of Litton, the Exchange Agent, or any other person shall
be under any duty to give notification of any irregularities in tenders or incur
any liability for failure to give such notification.

8. QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Questions and
requests for assistance may be directed to the Exchange Agent at its address and
telephone number set forth on the front of this Letter of Transmittal.
Additional copies of the Prospectus, the Notice of Guaranteed Delivery and the
Letter of Transmittal may be obtained from the Exchange Agent or from your
broker, dealer, commercial bank, trust company or other nominee.

9. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9. Under U.S. Federal income tax
law, a holder whose tendered Initial Notes are accepted for exchange is required
to provide the Exchange Agent with such holder's correct taxpayer identification
number ("TIN") on Substitute Form W-9 below. If the Exchange Agent is not
provided with the correct TIN, the Internal Revenue Service (the "IRS") may
subject the holder or other payee to a $50 penalty. In addition, payments to
such holders or other payees with respect to Initial Notes exchanged pursuant to
the Exchange Offer may be subject to 31% backup withholding.

The box in Part 2 of the Substitute Form W-9 may be checked if the tendering
holder has not been issued a TIN and has applied for a TIN or intends to apply
for a TIN in the near future. If the box in Part 2 is checked, the holder or
other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 2 is checked and the Certificate of
Awaiting Taxpayer Number is
                                       11
<PAGE>   12

completed, the Exchange Agent will withhold 31% of all payments made prior to
the time a properly certified TIN is provided to the Exchange Agent. The
Exchange Agent will retain such amounts withheld during the 60 day period
following the date of the Substitute Form W-9. If the holder furnishes the
Exchange Agent with its TIN within 60 days after the date of the Substitute Form
W-9, the amounts retained during the 60 day period will be remitted to the
holder and no further amounts shall be retained or withheld from payments made
to the holder thereafter. If, however, the holder has not provided the Exchange
Agent with its TIN within such 60 day period, amounts withheld will be remitted
to the IRS as backup withholding. In addition, 31% of all payments made
thereafter will be withheld and remitted to the IRS until a correct TIN is
provided.

The holder is required to give the Exchange Agent the TIN (e.g., social security
number or employer identification number) of the registered owner of the Initial
Notes or of the last transferal appearing, on the transfers attached to, or
endorsed on, the Initial Notes. If the Initial Notes are registered in more than
one name or are not in the name of the actual owner, consult the enclosed
"Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9" for additional guidance on which number to report.

Certain holders (including, among others, corporations, financial institutions
and certain foreign persons) may not be subject to these backup withholding and
reporting requirements. Such holders should nevertheless complete the attached
Substitute Form W-9 below, and write "exempt" on the face thereof, to avoid
possible erroneous backup withholding. A foreign person may qualify as an exempt
recipient by submitting a properly completed IRS Form W-8, signed under
penalties of perjury, attesting to that holder's exempt status. Please consult
the enclosed "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9" for additional guidance on which holders are exempt from
backup withholding.

Backup withholding is not an additional U.S. Federal income tax. Rather, the
U.S. Federal income tax liability of a person subject to backup withholding will
be reduced by the amount of tax withheld. If withholding results in an
overpayment of taxes, a refund may be obtained.

10. WAIVER OF CONDITIONS. Litton reserves the absolute right to waive
satisfaction of any or all conditions enumerated in the Prospectus.

11. NO CONDITIONAL TENDERS. No alternative, conditional, irregular or contingent
tenders will be accepted. All tendering holders of Initial Notes, by execution
of this Letter of Transmittal, shall waive any right to receive notice of the
acceptance of their Initial Notes for exchanges.

Neither Litton, any affiliates or assigns of Litton, the Exchange Agent nor any
other person is obligated to give notice of any defect or irregularity with
respect to any tender of Initial Notes nor shall any of them incur any liability
for failure to give any such notice.

12. LOST, DESTROYED OR STOLEN CERTIFICATES. If any Certificate(s) representing
Initial Notes have been lost, destroyed or stolen, the holder should promptly
notify the Exchange Agent. The holder will then be instructed as to the steps
that must be taken in order to replace the Certificate(s). This Letter of
Transmittal and related documents cannot be processed until the procedures for
replacing lost, destroyed or stolen Certificate(s) have been followed.

13. SECURITY TRANSFER TAXES. Holders who tender their Initial Notes for exchange
will not be obligated to pay any transfer taxes in connection therewith. If,
however, Initial Notes are to be delivered to, or are to be issued in the name
of, any person other than the registered holder of the Initial Notes tendered,
or if a transfer tax is imposed for any reason other than the exchange of
Initial Notes in connection with the Exchange Offer, then the amount of any such
transfer tax (whether imposed on the registered holder or any other persons)
will be payable by the tendering holder. If satisfactory evidence of payment of
such taxes or exemption therefrom is not submitted with the Letter of
Transmittal, the amount of such transfer taxes will be billed directly to such
tendering holder.

14. INCORPORATION OF LETTER OF TRANSMITTAL. This Letter of Transmittal shall be
deemed to be incorporated in and acknowledged and accepted by any tender through
DTC's ATOP procedures by any DTC participant on behalf of itself and the
beneficial owners of any Initial Notes tendered by book-entry transfer.

          IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF)
            AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY THE
            EXCHANGE AGENT ON OR PRIOR TO THE EXPIRATION DATE AND BE
