                       46,185,131 SHARES OF COMMON STOCK

     This prospectus relates to 46,185,131 shares (which we refer to as the
"contributed shares") of our common stock, par value $.01 per share, held in a
segregated account in the Lucent Technologies Inc. Represented Employees
Post-Retirement Health Benefits Trust (which we refer to as the "trust") created
under the Lucent Technologies Inc. Welfare Benefits Plan for Retired Employees
(which we refer to as the "plan"). The contributed shares may be offered for
sale from time to time by U.S. Trust Company, National Association (which we
refer to as the "investment manager"), in its capacity as duly appointed and
acting investment manager for the segregated account of the trust, and by Boston
Safe Deposit & Trust Company, as duly appointed trustee for the trust (which we
refer to as the "trustee," and we refer to the trustee, the trust and the
investment manager collectively as the "selling stockholder"). We are
registering the contributed shares to provide the selling stockholder with
freely tradable securities pursuant to a Registration Rights Agreement, dated as
of April 30, 2003 (which we refer to as the "registration rights agreement"),
between us and the investment manager. We will not receive any of the proceeds
from the sale of the contributed shares by the selling stockholder. We are
generally required to bear the expenses of the registration of the contributed
shares offered hereby, including, without limitation, registration fees under
federal and state securities laws, and legal and accounting fees. Any
underwriting discounts, brokerage fees and commissions will be the
responsibility of the selling stockholder. See "Selling Stockholder."

     The selling stockholder may sell all or a portion of the contributed shares
from time to time on the New York Stock Exchange, in negotiated transactions or
otherwise, and at prices which will be determined by the prevailing market price
for the contributed shares or in negotiated transactions.

     Our common stock is listed on the New York Stock Exchange under the symbol
"LU." On June 23, 2003, the last reported sale price per share of our common
stock on the New York Stock Exchange was $1.93.

                                USE OF PROCEEDS

     We will not receive any of the proceeds from the sale of the contributed
shares offered by this prospectus. The selling stockholder will receive all of
the proceeds.

                              SELLING STOCKHOLDER

     On April 30, 2003, we contributed to the trust 46,185,131 shares of our
common stock. We did not receive any cash proceeds from the contribution of the
contributed shares.

     The investment manager serves in its sole capacity as investment manager
pursuant to an investment management agreement with Lucent Asset Management
Corporation, a wholly-owned subsidiary of Lucent that is a named fiduciary of
the trust. In accordance with the terms of the investment management agreement,
the investment manager is responsible for the management and disposition of the
contributed shares and is a fiduciary of the trust. The investment manager, in
exercising its fiduciary duty, will decide whether or not, and
                                        2


under what terms, it will sell the contributed shares offered hereby. Both the
trustee and the investment manager receive customary compensation for serving as
trustee and investment manager, respectively.

     At the date of this prospectus, the trust beneficially owned 46,185,131
shares of our common stock, representing approximately 1.1% of our outstanding
shares of common stock. The selling stockholder may sell up to 46,185,131 shares
of our common stock pursuant to this offering, and assuming that all such
contributed shares are sold, the trust will beneficially own none of the
outstanding shares of our common stock after this offering. However, the selling
stockholder may sell all, some or none of the contributed shares. Accordingly,
we cannot provide you with an estimate of the number of shares of our common
stock that the selling stockholder will hold in the future.

     In some instances, the contributed shares may be sold by the pledgees,
donees, transferees, assignees or other successors-in-interest that receive
their shares from the selling stockholder as a gift, pledge or other non-sale
transfer after the date of this prospectus. The term "selling stockholder" as
used in this prospectus shall include such pledgees, donees, transferees,
assignees or other successors-in-interest.

                              PLAN OF DISTRIBUTION

     The selling stockholder may offer the contributed shares from time to time,
depending on market conditions and other factors, in one or more transactions on
the New York Stock Exchange or any other national securities exchange or
automated interdealer quotation system on which shares of our common stock are
then listed, through negotiated transactions or otherwise. The contributed
shares will be sold at prices and on terms then prevailing, at prices related to
the then current market price or at negotiated prices. Subject to the terms of
the registration rights agreement, the contributed shares may be offered in any
manner permitted by law, including through underwriters, brokers, dealers or
agents, and directly to one or more purchasers. Sales of the contributed shares
may involve:

     - sales to underwriters who will acquire contributed shares for their own
       account and resell them in one or more transactions at fixed prices or at
       varying prices determined at the time of sale;

     - block transactions in which the broker or dealer engaged will attempt to
       sell contributed shares as agent, but may position and resell a portion
       of the block as principal to facilitate the transaction;

     - purchases by a broker or dealer as principal and resale by the broker or
       dealer for its account; or

     - ordinary brokerage transactions and transactions in which a broker
       solicits purchasers.

     The selling stockholder and/or purchasers of the contributed shares may pay
brokers and dealers for selling contributed shares. These payments may be in the
form of underwriting discounts, concessions or commissions. The selling
stockholder and any broker dealer who sells or assists the selling stockholder
in selling contributed shares may be deemed an underwriter within the meaning of
the Securities Act of 1933, as amended (the "Securities Act"). If they are
deemed to be underwriters, any brokerage commissions or discounts may be deemed
to be underwriting discounts and commissions under the Securities Act. We will
file, if required, a prospectus supplement when the selling stockholder notifies
us that it has entered into an arrangement with an underwriter, broker or dealer
for the sale of contributed shares. The prospectus supplement will disclose
certain material information, including:

     - the number of contributed shares being offered;

     - the terms of the offering;

     - any discounts, commissions or other compensation paid to underwriters,
       brokers or dealers;

     - the public offering price;

     - any discounts, commissions or concessions allowed or reallowed or paid by
       any underwriters to dealers; and

     - other material terms of the offering.

                                        3


     As of the date of this prospectus, there are no selling arrangements
between the selling stockholder and any underwriter, broker or dealer. The
selling stockholder may also sell contributed shares in reliance upon Rule 144
of the Securities Act, provided it meets the criteria and conforms to the
requirements of Rule 144, rather than under this prospectus.

     We will not receive any of the proceeds from the sale of contributed shares
by the selling stockholder. We will bear the costs of registering the
contributed shares under the Securities Act, including the registration fee
under the Securities Act, accounting fees, printing fees, fees and disbursements
of our counsel and certain fees and disbursements of counsel to the selling
stockholder. The selling stockholder will be responsible for underwriting
discounts, brokerage fees and commissions, if any, incurred in connection with
the sale of contributed shares.

     Under the terms of the registration rights agreement, Lucent and the
selling stockholder have agreed to indemnify each other and certain other
related parties for certain liabilities in connection with the registration of
the contributed shares.

     All of the contributed shares are subject to the restrictions on transfer,
and other terms, set forth in the registration rights agreement. Under the
registration rights agreement, the selling stockholder may only transfer
contributed shares in the foregoing types of transactions, under certain
circumstances and in accordance with certain volume limitations set forth
therein. We have agreed to maintain the effectiveness of the registration
statement of which this prospectus is a part until April 30, 2005.

     The plan is a welfare plan as defined in the Employee Retirement Income
Security Act of 1974, as amended ("ERISA") and is designed to provide
participants and their beneficiaries with retiree healthcare related to their
years of active service. Prohibited transactions under Title I of ERISA and
Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code"),
could arise if, absent an available exemption, a person or entity which is a
"party in interest," as defined under ERISA, or a "disqualified person," as
defined under the Code, were to purchase any of the contributed shares being
offered by the selling stockholder. Any such potential purchaser should consult
with counsel to determine whether an exemption is available with respect to any
such purchase.

                                 LEGAL MATTERS

     Richard J. Rawson, our Senior Vice President, General Counsel and
Secretary, has delivered his legal opinion on behalf of the company to the
effect that the 46,185,131 shares offered hereby have been validly issued and
are fully paid and nonassessable. As of June 23, 2003, Mr. Rawson owned 334,071
shares of our common stock and vested options and stock units for 2,659,876
shares of our common stock.
