This Amendment No. 1 (this "Amendment") amends the Statement on Schedule 13D
filed on May 1, 2006 (the "Statement") by the Original Reporting Persons (as
defined in Item 2 below) and is filed by and on behalf of the Blue Harbour
Reporting Persons and Mr. Cooperman (each as defined in Item 2 below and
collectively, the "Reporting Persons") with respect to the common stock, par
value $0.01 per share ("Common Stock"), of Agere Systems Inc., a Delaware
corporation (the "Company"). Unless otherwise indicated, all capitalized terms
used herein have the meaning ascribed to them in the previous filing of the
Statement.

ITEM 2. IDENTITY AND BACKGROUND. Item 2 of the Statement is hereby amended and
restated in its entirety, with effect from the date of this Amendment, as
follows:

            This Amendment is filed by the Blue Harbour Reporting Persons and
Mr. Cooperman. The Statement was initially filed by the Fund, Fund GP, Manager,
Manager GP, Mr. Robbins and Mr. Cooperman (each as defined below), who are
herein referred to collectively as the "Original Reporting Persons."

            On May 1, 2006, certain of the Original Reporting Persons sent a
joint letter to Richard L. Clemmer, the Company's Chief Executive Officer,
regarding the Company's current and long-term prospects (the "May 1 Letter").
See Item 4 of the Statement.

            The Blue Harbour Reporting Persons and Mr. Cooperman do not have any
agreements or understandings between them relating to the acquisition,
disposition, holding or voting of Common Stock held by them and each expressly
disclaims beneficial ownership for all purposes of Common Stock held by the
others. The Blue Harbour Reporting Persons and Mr. Cooperman have, on occasion,
coordinated their market purchases of Common Stock and call options to purchase
Common Stock in the past, and may decide to coordinate purchases and sales in
the future. The Reporting Persons have filed this statement solely because they
may be deemed to be a "group" for purposes of Section 13(d) of the Securities
Exchange Act of 1934, as amended (the "Act"), as a result of their agreement to
submit the May 1 Letter to the Company's Chief Executive Officer. However, the
Blue Harbour Reporting Persons and Mr. Cooperman each disclaim membership in a
"group" with the other Reporting Person.

            (1) The Blue Harbour Reporting Persons.

            (a) - (c) and (f) The Blue Harbour Reporting Persons are Blue
Harbour Group, LP, a Delaware limited partnership ("Manager"), Blue Harbour
Strategic Value Partners Master Fund, LP, a Cayman Islands exempted limited
partnership (the "Fund"), Blue Harbour Institutional Partners Master Fund, L.P.,
a Cayman Islands exempted limited partnership ("BHIP" and, together with the
Fund, the "Funds"), Blue Harbour GP, LLC, a Delaware limited liability company
("Fund GP"), Blue Harbour Holdings, LLC, a Delaware limited liability company
("Manager GP"), and Clifton S. Robbins ("Mr. Robbins"), a citizen of the United
States of America.

            The address of the principal office of each of Manager, the Fund,
BHIP, Manager GP and Fund GP is 240 Greenwich Avenue, 3rd Floor, Greenwich,
Connecticut 06830, and Mr. Robbins' business address is c/o Manager at the
foregoing address. Mr. Robbins is the Chief Executive Officer of Manager.

            Each of the Fund and BHIP is principally involved in the business of
investing in securities. Fund GP is principally involved in the business of
serving as the general partner of the Funds. Manager is principally involved in
the business of providing investment advisory and investment management services


                                       9




to the Funds and its affiliates and, among other things, exercises all voting
and other powers and privileges attributable to any securities held for the
account of each of the Funds. Manager GP is principally involved in the business
of serving as the general partner of Manager.

            (d) - (e) During the last five years, none of the Blue Harbour
Reporting Persons nor, to the best of their knowledge, any of their officers and
directors, has (i) been convicted in a criminal proceeding (excluding traffic
violations or similar misdemeanors) or (ii) been a party to a civil proceeding
of a judicial or administrative body of competent jurisdiction and as a result
of such proceeding was or is subject to a judgment, decree or final order
enjoining future violations of, or prohibiting or mandating activities subject
to, federal or state securities laws or finding any violation with respect to
such laws.

            (2) Leon G. Cooperman.

            (a) - (c) and (f) Leon G. Cooperman ("Mr. Cooperman") is a citizen
of the United States of America.

            Mr. Cooperman is the Managing Member of Omega Associates, L.L.C., a
Delaware limited liability company ("Associates"). Associates is a private
investment firm formed to invest in and act as general partner of investment
partnerships or similar investment vehicles. Associates is the general partner
of limited partnerships organized under the laws of Delaware known as Omega
Capital Partners, L.P. ("Capital LP"), Omega Capital Investors, L.P. ("Investors
LP"), and Omega Equity Investors, L.P. ("Equity LP"). These entities are private
investment firms engaged in the purchase and sale of securities for investment
for their own accounts.

            Mr. Cooperman is also the President and majority stockholder of
Omega Advisors, Inc. ("Advisors"), a Delaware corporation engaged in providing
investment management services, and Mr. Cooperman is deemed to control said
entity. Advisors serves as the investment manager to Omega Overseas Partners,
Ltd. ("Overseas"), a Cayman Island exempted company, with a business address at
British American Tower, Third Floor, Jennrett Street, Georgetown, Grand Cayman
Island, British West Indies. Mr. Cooperman has investment discretion over
portfolio investments of Overseas and is deemed to control such investments.

            Advisors also serves as a discretionary investment advisor to a
limited number of institutional clients (the "Managed Accounts"). As to the
shares of Common Stock owned by the Managed Accounts, there would be shared
power to dispose or to direct the disposition of such shares because the owners
of the Managed Accounts may be deemed beneficial owners of such shares pursuant
to Rule 13d-3 under the Act, as a result of their right to terminate the
discretionary account within a period of 60 days.

            Mr. Cooperman is the ultimate controlling person of Associates,
Capital LP, Investors LP, Equity LP, and Advisors.

            The address of the principal office of each of Mr. Cooperman,
Associates, Capital LP, Investors LP, Equity LP and Advisors is 88 Pine Street,
Wall Street Plaza - 31st Floor, New York, NY 10005.

            (d) - (e) During the last five years, none of Mr. Cooperman or the
foregoing entities controlled by him, nor to the best of their knowledge, any of
their officers and directors, has (i) been convicted in a criminal proceeding


                                       10




(excluding traffic violations or similar misdemeanors) or (ii) been a party to a
civil proceeding of a judicial or administrative body of competent jurisdiction
and as a result of such proceeding was or is subject to a judgment, decree or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, federal or state securities laws or finding any violation
with respect to such laws.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. Item 3 of the
Statement is hereby amended and restated in its entirety, with effect from the
date of this Amendment, as follows:

            (1) The Blue Harbour Reporting Persons.

            The 6,632,547 shares of Common Stock reported herein by the Blue
Harbour Reporting Persons were acquired by the Funds for an aggregate purchase
price of approximately $79,214,960. All such purchases of Common Stock by each
of the Funds were funded by the working capital of the respective Funds, which
may, at any given time, include margin loans made by brokerage firms in the
ordinary course of business.

            (2) Leon G. Cooperman.

            The 5,633,900 shares of Common Stock reported herein by Mr.
Cooperman were acquired for an aggregate purchase price of approximately
$64,156,771. All such purchases of Common Stock by Mr. Cooperman were funded by
working capital, which may, at any given time, include margin loans made by
brokerage firms in the ordinary course of business.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.  Item 5 of the Statement is hereby
amended  and  restated  in its  entirety,  with  effect  from  the  date of this
Amendment, as follows:

            The Reporting Persons may be deemed to beneficially own collectively
an aggregate of 12,266,447 shares of Common Stock, representing approximately
7.2% of the shares of Common Stock presently outstanding, such percentage being
based on the number of shares of Common Stock outstanding as of May 1, 2006 (the
"Issued and Outstanding Shares") as set forth in the Company's Quarterly Report
on Form 10-Q for the period ended March 31, 2006. The Blue Harbour Reporting
Persons and Mr. Cooperman each expressly disclaims beneficial ownership for all
purposes of the shares of Common Stock held by the other Reporting Person.

            On May 5, 2006,  subsequent  to the filing of the  Statement  by the
Original Reporting Persons,  the Company filed its Quarterly Report on Form 10-Q
for the period  ended March 31,  2006,  which  reflected a decrease of 9,561,976
shares in the total number of shares of Common Stock outstanding.  Consequently,
the percentage of shares of Common Stock deemed to be beneficially  owned by the
Reporting Persons, as reported in this Amendment, reflects an increase resulting
from both the purchases of the Reporting  Persons,  as disclosed herein, and the
decrease in the total number of outstanding  shares of Common Stock, as reported
by the Company.

            (1) The Blue Harbour Reporting Persons.

            (a) The responses of the Blue Harbour Reporting Persons to Rows (11)
through (13) of the cover pages of this Schedule 13D are incorporated herein by
reference.





                                       11




            As  of  the  close  of  business  on  the  date  hereof,   the  Fund
beneficially owns an aggregate of 5,403,185 shares of Common Stock, representing
approximately  3.2% of the  shares of Common  Stock  based  upon the  Issued and
Outstanding  Shares and BHIP  beneficially owns an aggregate of 1,229,362 shares
of Common Stock,  representing  approximately 0.7% of the shares of Common Stock
based upon the Issued and  Outstanding  Shares.  The Fund is the direct owner of
5,403,185 shares of Common Stock reported by the Blue Harbour  Reporting Persons
on this  Statement  and BHIP is the direct owner of  1,229,362  shares of Common
Stock  reported by the Blue Harbour  Reporting  Persons on this  Statement.  For
purposes of disclosing  the number of shares  beneficially  owned by each of the
Blue  Harbour  Reporting  Persons,  Fund GP, as  general  partner  of the Funds,
Manager,  as the  investment  manager  of the Funds,  Manager GP as the  general
partner of Manager, and Mr. Robbins, as controlling owner of Fund GP and Manager
GP (in addition to serving as Chief Executive  Officer of Manager) may be deemed
to own  beneficially  (as that term is defined in Rule 13d-3  under the Act) all
shares of Common  Stock that are owned  beneficially  and directly by the Funds.
Fund GP, Manager,  Manager GP and Mr. Robbins disclaims  beneficial ownership of
such shares for all other purposes.

            (b) The responses of the Blue Harbour Reporting Persons to (i) Rows
(7) through (10) of the cover pages of this Statement and (ii) Item 5(a) hereof
are incorporated herein by reference.

preceding  the date  hereof.  All such  transactions  were  effected in the open
market,  unless  otherwise noted. The Funds have also entered into, and may from
time to time enter into, purchases and sales of shares of Common Stock with each
other.

            (d) No other person is known by the Blue Harbour Reporting Persons
to have the right to receive or the power to direct the receipt of dividends
from, or the proceeds from the sale of, the shares of Common Stock reported in
this Statement, except dividends from, or proceeds from the sale of, the shares
of Common Stock in the Fund and BHIP for which Manager acts as an investment
advisor, which may be distributed to the applicable limited partner entitled
thereto in accordance with their respective limited partnership interests in the
Fund and BHIP. Other than as described in Item 5 hereof, no investment
partnership or limited partner thereof has an interest in the shares of Common
Stock reported in this Statement representing more than five percent of the
Common Stock outstanding.

            (e) Not applicable.

            (2) Leon G. Cooperman.

            (a) As of the close of business on the date hereof, Mr. Cooperman

            (b) The responses of Mr. Cooperman to (i) Rows (7) through (10) of

respect to Mr. Cooperman and the foregoing entities controlled by him), none of
Mr. Cooperman or the foregoing entities controlled by him has effected any
transaction in shares of Common Stock during the 60 days preceding the date
hereof. All such transactions were effected in the open market, unless otherwise
noted.

            (d) No other person is known by Mr. Cooperman or the foregoing
entities controlled by him to have the right to receive or the power to direct
the receipt of dividends from, or the proceeds from the sale of, the shares of
Common Stock reported in this Statement, except dividends from, or proceeds from
