This Amendment No. 2 (this "Amendment") amends the Statement on Schedule 13D
filed on May 1, 2006 (the "Original Filing") by Blue Harbour Strategic Value
Partners Master Fund, LP, a Cayman Islands exempted limited partnership (the
"Fund"), Blue Harbour GP, LLC, a Delaware limited liability company ("Fund GP"),
Blue Harbour Group, LP, a Delaware limited partnership ("Manager"), Blue Harbour
Holdings, LLC, a Delaware limited liability company ("Manager GP"), Clifton S.
Robbins, a citizen of the United States of America ("Mr. Robbins") and Leon G.
Cooperman, a citizen of the United States of America ("Mr. Cooperman", and
together with the Fund, Fund GP, Manager, Manager GP and Mr. Robbins, the
"Original Reporting Persons"), which Original Filing was subsequently amended by
an Amendment No. 1 filed on July 25, 2006 (the "First Amendment" and, together
with the Original Filing, the "Statement") by the Original Reporting Persons and
Blue Harbour Institutional Partners Master Fund, L.P., a Cayman Islands exempted
limited partnership ("BHIP", and together with the Fund, the "Funds", and
together with the Original Reporting Persons, the "Reporting Persons", and
together with the Fund, Fund GP, Manager, Manager GP and Mr. Robbins, the "Blue
Harbour Reporting Persons") and is filed by and on behalf of 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 Statement.

For the reasons stated in Item 4 hereof, the Blue Harbour Reporting Persons and
Mr. Cooperman have determined that they no longer desire, and have no plans, to
coordinate their actions with respect to their respective investments in the
Company. Consequently, the Blue Harbour Reporting Persons and Mr. Cooperman do
not intend to jointly file any further amendments to the Statement.

ITEM 2.  IDENTITY AND BACKGROUND.

Item 2 of the Statement is hereby amended, with effect from the date of this
Amendment, by replacing the third paragraph of Item 2 with the following:

         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. Prior to the date hereof, the Blue Harbour Reporting Persons and Mr.
Cooperman had, on occasion, coordinated their market purchases of Common Stock
and call options to purchase Common Stock, but have no plans to do so in the
future. The Reporting Persons have filed this statement solely because they may
previously have been 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.

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 6,732,547 shares of Common Stock reported herein by the Blue
Harbour Reporting Persons were acquired by the Funds for an aggregate purchase
price of approximately $81,216,750. All such purchases of Common Stock by each
of the Funds were funded by the working capital of the respective Funds, which


                                       9




may, at any given time, include margin loans made by brokerage firms in the
ordinary course of business.

         (2) Leon G. Cooperman.

         The 5,733,900 shares of Common Stock reported herein by Mr. Cooperman
were acquired for an aggregate purchase price of approximately $66,226,545.
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 4.  PURPOSE OF TRANSACTION.

Item 4 of the Statement is hereby amended and restated in its entirety, with
effect from the date of this Amendment, as follows:

         On May 1, 2006, Mr. Robbins and Mr. Cooperman sent the May 1 Letter to
the Company's Chief Executive Officer relating to value enhancing initiatives
available to the company. The Reporting Persons believe the Company has taken
under advisement many of the suggestions raised in the May 1 Letter and has
implemented initiatives which the Reporting Persons believe are likely to
achieve many of the goals outlined in that letter. On December 4, 2006, the
Company announced that it had entered into a definitive merger agreement with
LSI Logic Corporation.

         In light of the foregoing, each of the Blue Harbour Reporting Persons
and Mr. Cooperman has determined that they no longer desire, and have no plans,
to coordinate their actions with respect to their respective investments in the
Company. In that regard, on December 18, 2006, the Original Reporting Persons
terminated that certain letter agreement, dated May 1, 2006, by and among the
Original Reporting Persons, which provided for the coordinated exchange of
information among the Original Reporting Persons in connection with the filing
of the Schedule 13D and amendments thereto.

         The Blue Harbour Reporting Persons and Mr. Cooperman have determined
that they no longer have any agreements, arrangements or understandings that
could deem them to be a "group" (within the meaning of Section 13(d)(3) of the
Act) and, accordingly, they do not intend to jointly file any further amendments
to the Statement. None of the Blue Harbour Reporting Persons or Mr. Cooperman
beneficially owns more than five percent of the outstanding shares of Common
Stock based on the number of shares of Common Stock outstanding as of November
24, 2006 (the "Issued and Outstanding Shares").

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:

         (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

                                       10

approximately 3.2% of the shares of Common Stock based upon the Issued and
Outstanding Shares and BHIP beneficially owns an aggregate of 1,304,362 shares

5,428,185 shares of Common Stock reported by the Blue Harbour Reporting Persons
on this Statement and BHIP is the direct owner of 1,304,362 shares of Common

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.

         (c) Except as set forth above or in the attached Schedule I (with
respect to the Blue Harbour Reporting Persons), no Blue Harbour Reporting Person
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. 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. No investment partnership or limited partner thereof has an

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) Each of the Blue Harbour Reporting Persons and Mr. Cooperman
expressly disclaims beneficial ownership for all purposes of Common Stock held
by the others. For the reasons stated in Item 4 hereof, each of the Blue Harbour
Reporting Persons and Mr. Cooperman have determined that they no longer desire,
and have no plans, to coordinate their actions with respect to their respective
investments in the Company. Therefore, each of the Blue Harbour Reporting
Persons and Mr. Cooperman do not own more than five percent of the shares of
Common Stock and will not be filing any further amendments to the Statement.
