                                EXPLANATORY NOTE



     This Amendment No. 1 amends and supplements the Registration Statement on
Form S-4 No. 333-116792 filed with the Securities and Exchange Commission on
June 23, 2004 (the "Registration Statement") by Lucent Technologies Inc.,
relating to the registration of its common stock to be issued to stockholders of
Telica, Inc. pursuant to the proposed merger of Telica and a newly-formed
subsidiary of Lucent.



     The sole purpose of this Amendment No. 1 is to amend Item 21 and to file
copies of the final executed versions of Exhibits 8.1 and 8.2.



                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The registrant's certificate of incorporation provides that a director of
the registrant shall not be personally liable to the registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except, if required by the General Corporation Law of the State of Delaware, for
liability (1) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (2) for acts or omissions not in good faith or
that involve intentional misconduct or a knowing violation of law, (3) under
Section 174 of the General Corporation Law of the State of Delaware or (4) for
any transaction from which the director derived an improper personal benefit.
Neither the amendment nor repeal of such provision shall eliminate or reduce the
effect of such provision in respect of any matter occurring, or any cause of
action, suit or claim that, but for such provision, would accrue or arise prior
to such amendment or repeal.

     While the registrant's certificate of incorporation provides directors with
protection from awards for monetary damages for breach of their duty of care, it
does not eliminate such duty. Accordingly, the registrant's certificate of
incorporation will have no effect on the availability of equitable remedies such
as an injunction or rescission based on a director's breach of his or her duty
of care.

     The registrant's certificate of incorporation provides that each person who
was or is made a party to or is threatened to be made a party to or is involved
in any action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), by reason of the fact that such
person, or a person of whom such person is the legal representative, is or was a
director or officer of the registrant or is or was serving at the request of the
registrant as a director, officer, employee or agent of another corporation or
of a partnership, joint venture, trust or other enterprise, including service
with respect to employee benefit plans, whether the basis of such proceeding is
alleged action in an official capacity as a director, officer, employee or agent
or in any other capacity while serving as a director, officer, employee or
agent, shall be indemnified and held harmless by the registrant to the fullest
extent authorized by the General Corporation Law of the State of Delaware, as
the same exists or may hereafter be amended (but, in the case of any such
amendment, only to the extent that such amendment permits the registrant to
provide broader indemnification rights than said law permitted the registrant to
provide prior to such amendment), against all expense, liability and loss
reasonably incurred or suffered by such person in connection therewith. Such
right to indemnification includes the right to have the registrant pay the
expenses incurred in defending any such proceeding in advance of its final
disposition, subject to the provisions of the General Corporation Law of the
State of Delaware. Such rights are not exclusive of any other right that any
person may have or hereafter acquire under any statute, provision of the
registrant's certificate of incorporation or by-laws, agreement, vote of
stockholders or disinterested directors or otherwise. No repeal or modification
of such provision will in any way diminish or adversely affect the rights of any
director, officer, employee or agent of the registrant thereunder in respect of
any occurrence or matter arising prior to any such repeal or modification.

     The registrant's certificate of incorporation also specifically authorizes
the registrant to maintain insurance and to grant similar indemnification rights
to employees or agents of the registrant. The directors and officers of the
registrant are covered by insurance policies indemnifying them against certain
liabilities, including certain liabilities arising under the Securities Act of
1933, which might be incurred by them in such capacities.

     The registrant has agreed in a consent decree with the Securities and
Exchange Commission that it shall not indemnify any person for the payment of
civil penalties, disgorgement, or prejudgment interest if such person is found
liable for fraud, in an action brought by the Securities and Exchange
Commission, unless such indemnification is required by the registrant's
certificate of incorporation (as in effect on May 6, 2004) or Delaware law.

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:

             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933.

             (ii) 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, represent 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 amount 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 percent change
        in the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement.

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

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to section 13 or section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

          (2) That, for the purpose 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.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which 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 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
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 bona fide offering thereof.

     (c) The undersigned registrant hereby undertakes as follows:

          (1) That prior to any public reoffering of the securities registered
     hereunder through use of a prospectus which is a part of this registration
     statement, by any person or party who is deemed to be an underwriter within
     the meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other items
     of the applicable form.

          (2) The registrant undertakes that every prospectus (i) that is filed
     pursuant to paragraph (c)(1) immediately preceding, or (ii) that purports
     to meet the requirements of Section 10(a)(3) of the Securities Act of 1933
     and is used in connection with an offering of securities subject to Rule
     415, will be filed as a part of an amendment to the registration statement
     and will not be used until such amendment is effective, and that, for
     purposes of determining any liability under the Securities Act of 1933,
     each such
                                       II-3


     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.

     (d) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 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 or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

     (e) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of this registration statement through
the date of responding to the request.

     (f) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                                       II-4
