                                                                               3

        There has been created a series of Preferred Stock of the Corporation
having the following designation, number of shares, relative rights, preferences
and limitations:

        (a)     Designation and Amount. The shares of such series shall be
designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall be 11,500,000. Such number of shares may be increased or decreased
by resolution of the Board of Directors; provided that no decrease shall reduce
the number of shares of Series A Preferred Stock to a number less than the
number of shares then outstanding plus the number of shares reserved for
issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.

        (b)     Dividends and Distributions.

                (A)     Subject to the rights of the holders of any shares of
any series of Preferred Stock (or any similar stock) ranking prior and superior
to the Series A Preferred Stock with respect to dividends, the holders of shares
of Series A Preferred Stock, in preference to the holders of Common Stock of the
Corporation, and of any other junior stock, shall be entitled to receive, when,
as and if declared by the Board of Directors out of funds legally available for
the purpose, quarterly dividends payable in cash on the first day of March,
June, September and December in each year (each such date being referred to
herein as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a share or fraction
of a share of Series A Preferred Stock, in an amount per share (rounded to the
nearest cent) equal to the greater of (a) $1 or (b) subject to the provision for
adjustment hereinafter set forth, 1,000 times the aggregate per share amount of
all cash dividends, and 1,000 times the aggregate per share amount (payable in
kind) of all non-cash dividends or other distributions, other than a dividend
payable in shares of Class A Common Stock or Class B Common Stock or a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock since the immediately preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment Date, since the first issuance of any share or fraction of a share of
Series A Preferred Stock. In the event the Corporation shall at any time after
March 27, 2001 declare and pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under clause (b) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                (B)     The Corporation shall declare a dividend or distribution
on the Series A Preferred Stock as provided in paragraph (A) of this subsection
(b) immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Quarterly Dividend

                                                                               4

Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend
of $1 per share on the Series A Preferred Stock shall nevertheless be payable on
such subsequent Quarterly Dividend Payment Date.

                (C)     Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares, unless the date of
issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date, in which case dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a
Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series A Preferred Stock entitled to
receive a quarterly dividend and before such Quarterly Dividend Payment Date, in
either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Series A Preferred Stock in
an amount less than the total amount of such dividends at the time accrued and
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding. The Board of Directors may fix a
record date for the determination of holders of shares of Series A Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be not more than 60 days prior to the date
fixed for the payment thereof.

        (c)     Voting Rights. The holders of shares of Series A Preferred Stock
shall have the following voting rights:

                (A)     Subject to the provision for adjustment hereinafter set
forth, each share of Series A Preferred Stock shall entitle the holder thereof
to 1,000 votes on all matters submitted to a vote of the stockholders of the
Corporation. In the event the Corporation shall at any time declare or pay any
dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the number of votes per share to which holders of shares of
Series A Preferred Stock were entitled immediately prior to such event shall be
adjusted by multiplying such number by a fraction, the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                (B)     Except as otherwise provided herein, in any other
Certificate of Designations creating a series of Preferred Stock or any similar
stock, or by law, the holders of shares of Series A Preferred Stock and the
holders of shares of Common Stock and any other capital stock of the Corporation
having general voting rights shall vote together as one class on all matters
submitted to a vote of stockholders of the Corporation.

                (C)     Except as set forth herein, or as otherwise provided by
law, holders of Series A Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for taking any corporate
action.

                                                                               5

                (D)     If, at the time of any annual meeting of stockholders
for the election of directors, the equivalent of six quarterly dividends
(whether or not consecutive) payable on any share or shares of Series A
Preferred Stock are in default, the number of directors constituting the Board
of Directors of the Corporation shall be increased by two. In addition to voting
together with the holders of Common Stock for the election of other directors of
the Corporation, the holders of record of the Series A Preferred Stock, voting
separately as a class to the exclusion of the holders of Common Stock, shall be
entitled at said meeting of stockholders (and at each subsequent annual meeting
of stockholders), unless all dividends in arrears on the Series A Preferred
Stock have been paid or declared and set apart for payment prior thereto, to
vote for the election of two directors of the Corporation, the holders of any
Series A Preferred Stock being entitled to cast a number of votes per share of
Series A Preferred Stock as is specified in paragraph (A) of this subsection
(c). Each such additional director shall not be classified, but shall serve
until the next annual meeting of stockholders for the election of directors, or
until his successor shall be elected and shall qualify, or until his right to
hold such office terminates pursuant to the provisions of this paragraph (D).
Until the default in payments of all dividends which permitted the election of
said directors shall cease to exist, any director who shall have been so elected
pursuant to the provisions of this paragraph (D) may be removed at any time,
without cause, only by the affirmative vote of the holders of the shares of
Series A Preferred Stock at the time entitled to cast a majority of the votes
entitled to be cast for the election of any such director at a special meeting
of such holders called for that purpose, and any vacancy thereby created may be
filled by the vote of such holders. If and when such default shall cease to
exist, the holders of the Series A Preferred Stock shall be divested of the
foregoing special voting rights, subject to revesting in the event of each and
every subsequent like default in payments of dividends. Upon the termination of
the foregoing special voting rights, the terms of office of all persons who may
have been elected directors pursuant to said special voting rights shall
forthwith terminate, and the number of directors constituting the Board of
Directors shall be reduced by two. The voting rights granted by this paragraph
(D) shall be in addition to any other voting rights granted to the holders of
the Series A Preferred Stock in this subsection (c).

        (d)     Certain Restrictions.

                (A)     Whenever quarterly dividends or other dividends or
distributions payable on the Series A Preferred Stock as provided in subsection
(b) are in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Preferred Stock
outstanding shall have been paid in full, the Corporation shall not:

                (i)     declare or pay dividends, or make any other
        distributions, on any shares of stock ranking junior (either as to
        dividends or upon liquidation, dissolution or winding up) to the Series
        A Preferred Stock;

                (ii)    declare or pay dividends, or make any other
        distributions, on any shares of stock ranking on a parity (either as to
        dividends or upon liquidation, dissolution or winding up) with the
        Series A Preferred Stock, except dividends paid ratably on the Series A
        Preferred Stock and all such parity stock on which dividends

                                                                               6

        are payable or in arrears in proportion to the total amounts to which
        the holders of all such shares are then entitled;

                (iii)   redeem or purchase or otherwise acquire for
        consideration shares of any stock ranking junior (either as to dividends
        or upon liquidation, dissolution or winding up) to the Series A
        Preferred stock, provided that the Corporation may at any time redeem,
        purchase or otherwise acquire shares of any such junior stock in
        exchange for shares of any stock of the Corporation ranking junior
        (either as to dividends or upon dissolution, liquidation or winding up)
        to the Series A Preferred Stock; or

                (iv)    redeem or purchase or otherwise acquire for
        consideration any shares of Series A Preferred Stock, or any shares of
        stock ranking on a parity with the Series A Preferred Stock, except in
        accordance with a purchase offer made in writing or by publication (as
        determined by the Board of Directors) to all holders of such shares upon
        such terms as the Board of Directors, after consideration of the
        respective annual dividend rates and other relative rights and
        preferences of the respective series and classes, shall determine in
        good faith will result in fair and equitable treatment among the
        respective series or classes.

                (B)     The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (A) of
this subsection (d), purchase or otherwise acquire such shares at such time and
in such manner.

        (e)     Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired promptly after the acquisition thereof. All such shares shall
upon their retirement become authorized but unissued shares of Preferred Stock
and may be reissued as part of a new series of Preferred Stock subject to the
conditions and restrictions on issuance set forth herein, in the Restated
Certificate of Incorporation, or in any other Certificate of Designations
creating a series of Preferred Stock or any similar stock or as otherwise
required by law.

        (f)     Liquidation, Dissolution or Winding Up. Upon any liquidation,
dissolution or winding up of the Corporation, no distribution shall be made (1)
to the holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless,
prior thereto, the holders of shares of Series A Preferred Stock shall have
received $1,000 per share, plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such payment,
provided that the holders of shares of Series A Preferred Stock shall be
entitled to receive an aggregate amount per share, subject to the provision for
adjustment hereinafter set forth, equal to 1,000 times the aggregate amount to
be distributed per share to holders of shares of Common Stock, or (2) to the
holders of shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Preferred Stock,
except distributions made ratably on the Series A Preferred Stock and all such
parity stock in proportion to the total amounts to which the holders of all such
shares are entitled upon such liquidation, dissolution or winding up. Neither
the merger or consolidation of the Corporation into or with another entity nor
the merger or consolidation of any other entity into or with the Corporation
shall be deemed to be a liquidation,

                                                                               7

dissolution or winding up of the Corporation within the meaning of this
subsection (f). In the event the Corporation shall at any time declare or pay
any dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the aggregate amount to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event under the proviso
in clause (1) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

        (g)     Consolidation, Merger, etc. In case the Corporation shall enter
into any consolidation, merger, combination or other transaction in which the
outstanding shares of Common Stock are exchanged for or changed into other stock
or securities, cash and/or any other property, then in any such case each share
of Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 1,000 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

        (h)     No Redemption. The shares of Series A Preferred Stock shall not
be redeemable.

        (i)     Ranking. The Series A Junior Participating Preferred Stock shall
rank junior to all other series of the Preferred Stock as to the payment of
dividends and as to the distribution of assets upon liquidation, dissolution or
winding up, unless the terms of any such series shall provide otherwise, and
shall rank senior to the Common Stock as to such matters.

        (j)     Amendment. At any time that any shares of Series A Preferred
Stock are outstanding, the Restated Certificate of Incorporation of the
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series A Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of at
least two-thirds of the outstanding shares of Series A Preferred Stock, voting
separately as a single class.

        SECTION 4.03. The relative powers, preferences and participating,
optional or other special rights, and the qualifications, limitations and
restrictions of the Class A

                                                                               8

Common Stock and Class B Common Stock of the Corporation shall be as described
below:

        (a)     Except as otherwise set forth below in this Article IV, the
relative powers, preferences and participating, optional or other special
rights, and the qualifications, limitations or restrictions of the Class A
Common Stock and Class B Common Stock shall be identical in all respects.

        (b)     Subject to the rights of the holders of Preferred Stock, and
subject to any other provisions of this Restated Certificate of Incorporation,
holders of Class A Common Stock and Class B Common Stock shall be entitled to
receive such dividends and other distributions in cash, stock of any entity
(other than Common Stock of the Corporation) or property of the Corporation as
may be declared thereon by the Board of Directors from time to time out of
assets or funds of the Corporation legally available therefor and shall share
equally on a per share basis in all such dividends and other distributions. In
the case of dividends or other distributions payable in Common Stock, including
distributions pursuant to stock splits or divisions of Common Stock of the
Corporation, only shares of Class A Common Stock shall be paid or distributed
with respect to Class A Common Stock and only shares of Class B Common Stock
shall be paid or distributed with respect to Class B Common Stock. The number of
shares of Class A Common Stock and Class B Common Stock so distributed on each
share shall be equal in number. Neither the shares of Class A Common Stock nor
the shares of Class B Common Stock may be reclassified, subdivided or combined
unless such reclassification, subdivision or combination occurs simultaneously
and in the same proportion for each class.

        (c)     (1)     At every meeting of the stockholders of the Corporation
every holder of Class A Common Stock shall be entitled to one vote in person or
by proxy for each share of Class A Common Stock standing in his or her name on
the transfer books of the Corporation in connection with all matters submitted
to a vote of stockholders (subject to the terms of this Restated Certificate of
Incorporation), and every holder of Class B Common Stock shall be entitled to
four votes in person or by proxy for each share of Class B Common Stock standing
in his or her name on the transfer books of the Corporation in connection with
the election and removal of directors and one vote in person or by proxy for
each share of Class B Common Stock standing in his or her name on the transfer
books of the Corporation for all other matters submitted to a vote of
stockholders. Except as may be otherwise required by law or by this Restated
Certificate of Incorporation, the holders of Class A Common Stock and Class B
Common Stock shall vote together as a single class and their votes shall be
counted and totaled together, subject to any voting rights which may be granted
to holders of Preferred Stock, on all matters submitted to a vote of
stockholders of the Corporation. Notwithstanding any other provision of this
Restated Certificate of Incorporation to the contrary, holders of Class A Common
Stock shall not be eligible to vote on any alteration or change in the powers,
preferences, or special rights of the Class B Common Stock that would not
adversely affect the rights of the Class A Common Stock; provided that, for the
foregoing purposes, any alteration or change with respect to, and any provision
for, the voluntary, mandatory or other conversion or exchange of the Class B
Common Stock into or for Class A Common Stock on a one-for-one basis shall be
deemed not to adversely affect the rights of the Class A Common Stock.

                (2)     Except as otherwise provided by law, and subject to any
rights of the holders of Preferred Stock, the provisions of this Restated
Certificate of Incorporation shall not be modified, revised, altered or amended,
repealed or rescinded in whole or in part, without the approval of a majority of
the votes entitled to be cast by the holders of outstanding shares of the Class
A Common Stock and the Class B Common Stock, voting together as a single class
(except as otherwise provided in paragraph (c)(1) of this Section 4.03 above);
provided, however, that with respect to any proposed amendment of this Restated
Certificate of Incorporation which would alter or change the powers, preferences
or special rights of the shares of Class A Common Stock or Class B Common Stock
so as to affect them adversely, the approval of a majority of the votes entitled
to be cast by the holders of the outstanding shares of the class affected by the
proposed amendment, voting separately as a class, shall be obtained in addition
to the approval of a majority of the votes entitled to be cast by the holders of
outstanding shares of the Class A Common Stock and the Class B Common Stock
voting together as a single class as hereinbefore provided (except as otherwise
provided in paragraph (c)(i) of this Section 4.03 above). To the fullest extent
permitted by law, any increase in the authorized number of shares of any class
or classes of stock of the Corporation or creation, authorization or issuance of
any securities convertible into, or warrants, options or similar rights to
purchase, acquire or receive, shares of any such class or classes of stock shall
be deemed not to affect adversely the powers, preferences or special rights of
the shares of Class A Common Stock or Class B Common Stock.

                (3)     Except as otherwise provided herein, every reference in
this Restated Certificate of Incorporation to a majority or other proportion of
shares, or a majority or other proportion of the votes of shares, of Voting
Stock, Common Stock, Class A Common Stock, or Class B Common Stock shall refer
to such majority or other proportion of the votes to which such shares of Voting
Stock, Common Stock, Class A Common Stock or Class B Common Stock are entitled
to cast. "Voting Stock" shall mean the then outstanding shares of capital stock
entitled to vote generally on the election of directors and shall exclude any
class or series of capital stock only entitled to vote in the event of dividend
arrearages thereon, whether or not at the time of determination there are any
such dividend arrearages.

        (d)     In the event of any dissolution, liquidation or winding up of
the affairs of the Corporation, whether voluntary or involuntary, after payment
in full of the amounts required to be paid to the holders of Preferred Stock,
the remaining assets and funds of the Corporation shall be distributed pro rata
to the holders of Common Stock, and the holders of Class A Common Stock and the
holders of Class B Common Stock will be entitled to receive the same amount per
share in respect thereof. For purposes of this paragraph (d), the sale,
conveyance, lease, exchange or transfer (for cash, shares of stock, securities
or other consideration) of all or substantially all of the assets of the
Corporation or a consolidation or merger of the Corporation with one or more
other entities (whether or not the Corporation is the entity surviving such
consolidation or merger), in each case, that is voluntary, shall not be deemed
to be a liquidation, dissolution or winding up, voluntary or involuntary.

        (e)     Except as shall otherwise be approved by a majority of the votes
entitled to be cast by the holders of the outstanding shares of each class of
Common Stock voting separately as a class, in case of any reorganization or any
consolidation of the Corporation

                                                                              10

with one or more other entities or a merger of the Corporation with another
entity in which shares of Class A Common Stock or Class B Common Stock are
converted into (or entitled to receive with respect thereto) shares of stock
and/or other securities or property (including cash), each holder of a share of
Class A Common Stock shall be entitled to receive with respect to such share the
same kind and amount of shares of stock and other securities and property
(including cash) receivable upon such reorganization, consolidation or merger by
a holder of a share of Class B Common Stock and each holder of a share of Class
B Common Stock shall be entitled to receive with respect to such share the same
kind and amount of shares of stock and other securities and property (including
cash) receivable upon such reorganization, consolidation or merger by a holder
of a share of Class A Common Stock. In the event that the holders of Class A
Common Stock (or of Class B Common Stock) are granted rights to elect to receive
one of two or more alternative forms of consideration, the foregoing provision
shall be deemed satisfied if holders of Class A Common Stock and holders of
Class B Common Stock are granted substantially identical election rights.

        (f)     (1)     Prior to the date on which shares of Class B Common
Stock are transferred to stockholders of Lucent Technologies Inc. in a Tax-Free
Spin-Off (as defined in paragraph (f)(2) of this Section 4.03 below), each
record holder of shares of Class B Common Stock may convert any or all of such
shares into an equal number of shares of Class A Common Stock by surrendering
the certificates for such shares, accompanied by any payment required for
documentary, stamp or similar issue or transfer taxes and by a written notice by
such record holder to the Corporation stating that such record holder desires to
convert such shares of Class B Common Stock into the same number of shares of
Class A Common Stock including for the purpose of the sale or other disposition
of such shares of Class A Common Stock, and requesting that the Corporation
issue all of such shares of Class A Common Stock to persons named therein,
setting forth the number of shares of Class A Common Stock to be issued to each
such person and the denominations in which the certificates therefor are to be
issued. To the extent permitted by law, such voluntary conversion shall be
deemed to have been effected at the close of business on the date of such
surrender. Following a Tax-Free Spin-Off, shares of Class B Common Stock shall
no longer be convertible into shares of Class A Common Stock.

                (2)     Prior to a Tax-Free Spin-Off, each share of Class B
Common Stock shall automatically be converted into one share of Class A Common
Stock upon the transfer of such share if, after such transfer, such share is not
beneficially owned by Lucent. Shares of Class B Common stock shall not convert
into shares of Class A Common Stock (A) in any transfer effected in connection
with a distribution of Class B Common Stock to security holders of Lucent
Technologies Inc. in a transaction (including any distribution in exchange for
or in respect of shares of capital stock or securities of Lucent Technologies
Inc.) intended to qualify as a tax-free distribution under Section 355 of the
Internal Revenue Code of 1986, as amended (the "Code"), or any successor
provision (a "Tax-Free Spin-Off") or (B) in any transfer after a Tax-Free
Spin-Off. For purposes of this paragraph (f) of this Section 4.03, a Tax-Free
Spin-Off shall be deemed to have occurred at the time shares are first
transferred to stockholders of Lucent Technologies Inc. following receipt of an
affidavit described in paragraph (f)(4) of this Section 4.03 below. For purposes
of this paragraph (f) of this Section 4.03, each reference to a "person" shall
be deemed to include not only a natural person, but also a corporation,
partnership, limited liability company, joint venture, association, or other
legal entity of any kind; each reference

<PAGE>   11

                                                                              11

to a "natural person" (or to a "record holder" of shares, if a natural person)
shall be deemed to include in his or her representative capacity a guardian,
committee, executor, administrator or other legal representative of such natural
person or record holder.

                For purposes of this Restated Certificate of Incorporation:

                        A.      "Lucent Technologies Inc." shall mean Lucent
        Technologies Inc., a Delaware corporation, and all its successors by way
        of merger, consolidation or sale of all or substantially all of its
        assets;

                        B.      The term "subsidiary" shall mean, as to any
        person or entity, a corporation, partnership, limited liability company,
        joint venture, association or other legal entity of any kind in which
        such person or entity beneficially owns (directly or indirectly) 50% or
        more of the outstanding voting stock, voting power, partnership
        interests or similar voting interests;

                        C.      "Lucent" shall mean Lucent Technologies Inc. and
        all its subsidiaries, but shall not include the Corporation and its
        subsidiaries; and

                        D.      "affiliate" and "beneficial ownership" shall
        have the respective meanings given to such terms in Rule 13d-3
        promulgated under the Securities Exchange Act of 1934, as amended.

                Each share of Class B Common Stock shall automatically be
converted into one share of Class A Common Stock on the date on which the
outstanding shares of Class B Common Stock beneficially owned by Lucent
represent less than 50% of the aggregate number of shares of the then
outstanding Common Stock, provided that a Tax-Free Spin-Off has not occurred.
For the avoidance of doubt, paragraph (c)(3) of this Section 4.03 shall not
apply to the preceding sentence.

                Immediately upon such conversion, the rights of the holders of
shares of Class B Common Stock as such shall cease and such holders shall be
treated for all purposes as having become the record owners of the shares of
Class A Common Stock issuable upon such conversion; provided, however, that such
persons shall be entitled to receive when paid any dividends declared on the
Class B Common Stock as of a record date preceding the time of such conversion
and unpaid as of the time of such conversion, subject to paragraph (f)(6) of
this Section 4.03 below.

                (3)     Prior to a Tax-Free Spin-Off, holders of shares of Class
B Common Stock may (A) sell or otherwise dispose of or transfer any or all of
such shares held by them, respectively, only in connection with a transfer which
meets the qualifications of paragraph (f)(4) below, and under no other
circumstances, or (B) convert any or all of such shares into shares of Class A
Common Stock, including for the purpose of effecting the sale or disposition of
such shares of Class A Common Stock to any person as provided in paragraph
(f)(1) of this Section 4.03 above. Prior to a Tax-Free Spin-Off, no one other
than those persons in whose names shares of Class B Common Stock become
registered on the original stock ledger of the Corporation by reason of their
record ownership of shares of common stock of the Corporation which are
reclassified into shares of Class B Common Stock as provided in paragraph
(f)(l2) of this Section 4.03 below, or transferees or

<PAGE>   12

                                                                              12

successive transferees who receive shares of Class B Common Stock in connection
with a transfer which meets the qualifications set forth in paragraph (f)(4) of
this Section 4.03 below, shall by virtue of the acquisition of a certificate for
shares of Class B Common Stock have the status of an owner or holder of shares
of Class B Common Stock or be recognized as such by the Corporation or be
otherwise entitled to enjoy for his or her own benefit the special rights and
powers of a holder of shares of Class B Common Stock.

                Holders of shares of Class B Common Stock may at any and all
times transfer to any person the shares of Class A Common Stock issuable upon
conversion of such shares of Class B Common Stock.

                (4)     Prior to a Tax-Free Spin-Off, shares of Class B Common
Stock may be transferred on the books of the Corporation and a new certificate
therefor issued only if such transfer is from Lucent Technologies Inc. to one of
its subsidiaries, from any such subsidiary to Lucent Technologies Inc., from one
subsidiary of Lucent Technologies Inc. to another such subsidiary or from Lucent
Technologies Inc. to its stockholders in connection with a Tax-Free Spin-Off.
Any such transfer and issuance shall be effected, upon presentation at the
office of the Secretary of the Corporation (or at such additional place or
places as may from time to time be designated by the Secretary or any Assistant
Secretary of the Corporation) of the certificate for such shares, in proper form
for transfer and accompanied by all requisite stock transfer tax stamps,
together with an affidavit of Lucent Technologies Inc. stating the basis upon
which such transfer is permitted pursuant to the foregoing sentence.

                Each affidavit of a record holder furnished pursuant to this
paragraph (f)(4) shall be verified as of a date not earlier than five days prior
to the date of delivery thereof, and, where such record holder is a corporation
or partnership, shall be verified by an officer of the corporation or by a
general partner of the partnership, as the case may be.

                If a record holder of shares of Class B Common Stock shall
deliver a certificate for such shares, endorsed by such record holder for
transfer or accompanied by an instrument of transfer signed by such record
holder, to a person who receives such shares in connection with a transfer which
does not meet the qualifications set forth in this paragraph (f)(4) of this
Section 4.03, then such person (or any successive transferee of such
certificate) may treat such endorsement or instrument as authorizing such person
(or such transferee) on behalf of such record holder to convert such shares in
the manner above provided for the purpose of the transfer to such person (or
such transferee) of the shares of Class A Common Stock issuable upon such
conversion, and to give on behalf of such record holder the written notice of
conversion above required, and may convert such shares of Class B Common Stock
accordingly.

                If such shares of Class B Common Stock shall improperly have
been registered in the name of a person not meeting the qualifications set forth
in this paragraph (f)(4)(or in the name of any successive transferee of such
certificate) and a new certificate therefor issued, such person or transferee
shall surrender such new certificate for cancellation, accompanied by the
written notice of conversion above required, in which case (A) such person or
transferee shall be deemed to have elected to treat the endorsement on (or
instrument of transfer accompanying) the certificate so delivered by such former
record holder as authorizing such person or transferee on behalf of such

<PAGE>   13

                                                                              13

former record holder so to convert such shares and so to give such notice, (B)
the shares of Class B Common Stock registered in the name of such former record
holder shall be deemed to have been surrendered for conversion as of the time of
the transfer for the purpose of the transfer to such person or transferee of the
shares of Class A Common Stock issuable upon conversion, and (C) the appropriate
entries shall be made on the books of the Corporation to reflect such action.

                In the event that the Board of Directors of the Corporation (or
any committee of the Board of Directors, or any officer of the Corporation,
designated for the purpose by the Board of Directors) shall determine, upon the
basis of facts not disclosed in any affidavit or other document accompanying the
certificate for shares of Class B Common Stock when presented for transfer, that
such shares of Class B Common Stock have been registered in violation of the
provisions of paragraph (f) of this Section 4.03, or shall determine that a
person is enjoying for his or her own benefit the special rights and powers of
shares of Class B Common Stock in violation of such provisions, then the
Corporation shall take such action at law or in equity as is appropriate under
the circumstances. An unforeclosed pledge made to secure a bona fide obligation
shall not be deemed to violate such provisions. A holder of shares of Class B
Common Stock shall be permitted to pledge such shares; provided that prior to
the occurrence of a Tax-Free Spin-Off, no transfer of title to shares of Class B
Common Stock to a pledgee or other person (other than Lucent) may occur without
compliance with the provisions of the previous two subparagraphs of this
paragraph (f)(4).

                (5)     Prior to a Tax-Free Spin-Off, every certificate for
shares of Class B Common Stock shall bear a conspicuous legend on the face
thereof reading as follows:

                        "The shares of Class B Common Stock represented by this
                certificate may not be transferred to any person in connection
                with a transfer that does not meet the qualifications set forth
                in paragraph (f)(4) of Section 4.03 of the Restated Certificate
                of Incorporation of this corporation and no person who receives
                such shares in connection with a transfer which does not meet
                the qualifications prescribed by paragraph (f)(4) of said
                Section 4.03 is entitled to own or to be registered as the
                record holder of such shares of Class B Common Stock, but the
                record holder of this certificate may at such time and in the
                manner set forth in said Article IV of the Restated Certificate
                of Incorporation convert such shares of Class B Common Stock
                into the same number of shares of Class A Common Stock for
                purposes of effecting the sale or other disposition of such
                shares of Class A Common Stock to any person. Each holder of
                this certificate, by accepting the same, accepts and agrees to
                all of the foregoing."

                Upon and after the transfer of shares in a Tax-Free Spin-Off,
shares of Class B Common Stock shall no longer bear the legend set forth above
in this paragraph (f)(5).

                (6)     Upon any conversion of shares of Class B Common Stock
into shares of Class A Common Stock pursuant to the provisions of this paragraph
(f), any

                                                                              14

dividend, for which the record date or payment date shall be subsequent to such
conversion, which may have been declared on the shares of Class B Common Stock
so converted shall be deemed to have been declared, and shall be payable, with
respect to the shares of Class A Common Stock into or for which such shares of
Class B Common Stock shall have been so converted, and any such dividend which
shall have been declared on such shares payable in shares of Class B Common
Stock shall be deemed to have been declared, and shall be payable, in shares of
Class A Common Stock.

                (7)     Prior to a Tax-Free Spin-Off, the Corporation shall at
all times reserve and keep available, out of its authorized but unissued Common
Stock, such number of shares of Class A Common Stock as would become issuable
upon the conversion of all shares of Class B Common Stock then outstanding.

                (8)     In connection with any transfer or conversion of any
stock of the Corporation pursuant to or as permitted by the provisions of this
paragraph (f), or in connection with the making of any determination referred to
in this paragraph (f), the Corporation shall be under no obligation to make any
investigation of facts unless an officer, employee or agent of the Corporation
responsible for making such transfer or determination or issuing Class A Common
Stock pursuant to such conversion has substantial reason to believe, or unless
the Board of Directors (or a committee of the Board of Directors designated for
the purpose) determines that there is substantial reason to believe, that any
affidavit or other document is incomplete or incorrect in a material respect or
that an investigation would disclose facts upon which any determination referred
to in paragraph (f)(4) of this Section 4.03 above should be made, in either of
which events the Corporation shall make or cause to be made such investigation
as it may deem necessary or desirable in the circumstances and have a reasonable
time to complete such investigation.

                (9)     The Corporation will not be required to pay any
documentary, stamp or similar issue or transfer taxes payable in respect of the
issue or delivery of shares of Class A Common Stock on the conversion of shares
of Class B Common Stock pursuant to this paragraph (f), and no such issue or
delivery shall be made unless and until the person requesting such issue has
paid to the Corporation the amount of any such tax or has established, to the
satisfaction of the Corporation, that such tax has been paid.

                (10)    All rights to vote and all voting power (including,
without limitation, the right to elect directors) shall be vested exclusively in
the holders of Common Stock, voting together as a single class, except as
otherwise expressly provided in this Restated Certificate of Incorporation, in a
Certificate of Designation with respect to any Preferred Stock or as otherwise
expressly required by applicable law.

                (11)    No stockholder shall be entitled to exercise any right
of cumulative voting.

                (12)    Immediately upon the effectiveness of this Restated
Certificate of Incorporation, each share of common stock of the Corporation
issued and outstanding immediately prior to such effectiveness, shall be
reclassified as 1,035,100 shares of Class B Common Stock.

                                                                              15

                                    ARTICLE V
                               Stockholder Action

        SECTION 5.01. Effective as of the time at which Lucent Technologies Inc.
shall cease to be the beneficial owner of an aggregate of at least a majority of
the aggregate number of shares of the then outstanding Common Stock (the
"Trigger Date"), any action required or permitted to be taken by the
stockholders of the Corporation must be effected at a duly called annual or
special meeting of such holders and may not be effected by any consent in
writing by such holders. For the avoidance of doubt, Section 4.03 (c)(3) of this
Restated Certificate of Incorporation shall not apply to the preceding sentence.
Effective as of the Trigger Date, except as otherwise required by law and
subject to the rights of the holders of any class or series of stock having a
preference over the Common Stock as to dividends or upon liquidation, special
meetings of stockholders of the Corporation for any purpose or purposes may be
called only by the Board of Directors pursuant to a resolution stating the
purpose or purposes thereof approved by a majority of the total number of
Directors which the Corporation would have if there were no vacancies (the
"Whole Board") or by the Chairman of the Board of Directors and, effective as of
the Trigger Date, any power of stockholders to call a special meeting is
specifically denied. No business other than that stated in the notice shall be
transacted at any special meeting. Notwithstanding anything contained in this
Restated Certificate of Incorporation to the contrary, the affirmative vote of
the holders of at least 80% of the voting power (determined based on the matter
being voted on) of all shares of Voting Stock then outstanding, voting together
as a single class, shall be required to alter, amend, adopt any provision
inconsistent with or repeal this Article V.

                                   ARTICLE VI
                              Election of Directors

        SECTION 6.01. Unless and except to the extent that the By-laws of the
Corporation (the "By-laws") shall so require, the election of Directors of the
Corporation need not be by written ballot.

                                   ARTICLE VII
                               Board of Directors

        SECTION 7.01. Number, election and terms. Except as otherwise fixed by
or pursuant to the provisions of Article IV hereof relating to the rights of the
holders of any class or series of stock having a preference over the Common
Stock as to dividends or upon liquidation to elect additional Directors under
specified circumstances, the number of the Directors shall be fixed from time to
time exclusively pursuant to a resolution adopted by a majority of the Whole
Board (but shall not be less than three). The Directors, other than those who
may be elected by the holders of any class or series of stock having a
preference over the Common Stock as to dividends or upon liquidation, shall be
classified, with respect to the time for which they severally hold office, into
three classes, as nearly equal in number as possible, one class to be originally
elected for a term expiring at the first annual meeting of stockholders
following the effectiveness of this Restated Certificate of Incorporation,
another class to be originally elected for a term expiring at the second annual
meeting of stockholders following the effectiveness of this Restated Certificate
of Incorporation, and another class to be originally elected for a term expiring
at the third

                                                                              16

annual meeting of stockholders following the effectiveness of this Restated
Certificate of Incorporation, with each class to hold office until its successor
is duly elected and qualified. At each annual meeting of stockholders, Directors
elected to succeed those Directors whose terms then expire shall be elected for
a term of office to expire at the third succeeding annual meeting of
stockholders after their election, with each Director to hold office until such
person's successor shall have been duly elected and qualified.

        SECTION 7.02. Stockholder nomination of Director candidates; Stockholder
proposal of business. Advance notice of stockholder nominations for the election
of Directors and of the proposal of business by stockholders shall be given in
the manner provided in the By-laws, as amended and in effect from time to time.

        SECTION 7.03. Newly created directorships and vacancies. Except as
otherwise provided for or fixed by or pursuant to the provisions of Article IV
hereof relating to the rights of the holders of any class or series of stock
having a preference over the Common Stock as to dividends or upon liquidation to
elect Directors under specified circumstances, newly created directorships
resulting from any increase in the number of Directors and any vacancies on the
Board of Directors resulting from death, resignation, disqualification, removal
or other cause shall be filled by the affirmative vote of a majority of the
remaining Directors then in office, even though less than a quorum of the Board
of Directors, and not by the stockholders. Any Director elected in accordance
with the preceding sentence shall hold office for the remainder of the full term
of the class of Directors in which the new directorship was created or the
vacancy occurred and until such Director's successor shall have been duly
elected and qualified. No decrease in the number of Directors constituting the
Board of Directors shall shorten the term of any incumbent Director.

        SECTION 7.04. Removal. Subject to the rights of any class or series of
stock having a preference over the Common Stock as to dividends or upon
liquidation to elect and remove Directors under specified circumstances, (i)
prior to the Trigger Date, any Director may be removed from office, with or
without cause, by the affirmative vote of the holders of at least a majority of
the voting power of all Voting Stock then outstanding, voting together as a
single class and (ii) on and after the Trigger Date, any director may be removed
from office only for cause by the affirmative vote of the holders of at least a
majority of the voting power of all Voting Stock then outstanding, voting
together as a single class.

        SECTION 7.05. Amendment, repeal, etc. Notwithstanding anything contained
in this Restated Certificate of Incorporation to the contrary, the affirmative
vote of the holders of at least 80% of the voting power (determined based on the
matter being voted on) of all Voting Stock then outstanding, voting together as
a single class, shall be required to alter, amend, adopt any provision
inconsistent with or repeal this Article VII.

                                  ARTICLE VIII
                                     By-laws

        SECTION 8.01. The By-laws may be altered or repealed and new By-laws may
be adopted (a) at any annual or special meeting of stockholders, by the
affirmative vote of the holders of a majority of the voting power (determined
based on the matter being voted on) of the Voting Stock then outstanding, voting
together as a single class; provided, however, that any proposed alteration or
repeal of, or the adoption of any By-law inconsistent with, Section 2.02 or 2.07
of the By-laws or this sentence, by the stockholders shall require the
affirmative vote of the holders of at least 80% of the voting power (determined
based on the matter being voted on) of all Voting Stock then outstanding, voting
together as a single class; provided, further, however, that in the case of any
such stockholder action at a special meeting of stockholders, notice of the

                                                                              18

Section 10.01 in respect of any matter occurring, or any cause of action, suit
or claim that, but for this Section 10.01 would accrue or arise, prior to such
amendment or repeal.

        SECTION 10.02. Indemnification and Insurance. (a) Right to
Indemnification. Each person who was or is made a party 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 Corporation or,
while a Director or officer of the Corporation, is or was serving at the request
of the Corporation as a Director, officer, employee or agent of another
corporation or of a partnership, limited liability company, joint venture, trust
or other legal entity of any kind, 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 Corporation to the fullest extent
authorized by the DGCL, as the same exists or may hereafter be amended, against
all expense, liability and loss (including attorneys' fees, judgments, fines,
amounts paid or to be paid in settlement, and excise taxes or penalties arising
under the Employee Retirement Income Security Act of 1974, as in effect from
time to time) reasonably incurred or suffered by such person in connection
therewith and such indemnification shall continue as to a person who has ceased
to be a Director, officer, employee or agent and shall inure to the benefit of
such person's heirs, executors and administrators; provided, however, that,
except as provided in paragraph (b) hereof, the Corporation shall indemnify any
such person seeking indemnification in connection with a proceeding (or part
thereof) initiated by such person only if such proceeding (or part thereof) was
authorized by the Board of Directors. The Corporation shall pay the expenses
incurred in defending any such proceeding in advance of its final disposition;
any advance payments to be paid by the Corporation within 20 calendar days after
the receipt by the Corporation of a statement or statements from the claimant
requesting such advance or advances from time to time; provided, however, that,
if and to the extent the DGCL requires, the payment of such expenses incurred by
a Director or officer in such person's capacity as a Director or officer (and
not in any other capacity in which service was or is rendered by such person
while a Director or officer, including, without limitation, service to an
employee benefit plan) in advance of the final disposition of a proceeding,
shall be made only upon delivery to the Corporation of an undertaking, by or on
behalf of such Director or officer, to repay all amounts so advanced if it shall
ultimately be determined that such Director or officer is not entitled to be
indemnified under this Section 10.02 or otherwise. The Corporation may, to the
extent authorized from time to time by the Board of Directors, grant rights to
indemnification, and rights to have the Corporation pay the expenses incurred in
defending any proceeding in advance of its final disposition, to any employee or
agent of the Corporation to the fullest extent of the provisions of this Article
with respect to the indemnification and advancement of expenses of Directors and
officers of the Corporation.

        (b)     Right of Claimant to Bring Suit. If a claim under paragraph (a)
of this Section 10.02 is not paid in full by the Corporation within 30 calendar
days after a written claim has been received by the Corporation, the claimant
may at any time thereafter bring suit against the Corporation to recover the
unpaid amount of the claim and, if successful in whole or in part, the claimant
shall be entitled to be paid also the expense of prosecuting such claim. It
shall be a defense to any such action (other than an action brought to

<PAGE>   19

                                                                              19

enforce a claim for expenses incurred in defending any proceeding in advance of
its final disposition where the required undertaking, if any is required, has
been tendered to the Corporation) that the claimant has not met the standard of
conduct which makes it permissible under the DGCL for the Corporation to
indemnify the claimant for the amount claimed, but the burden of proving such
defense shall be on the Corporation. Neither the failure of the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because the claimant has met the applicable standard of conduct set forth in the
DGCL, nor an actual determination by the Corporation (including its Board of
Directors, independent legal counsel, or its stockholders) that the claimant has
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.

        (c)     Non-Exclusivity of Rights. The right to indemnification and the
payment of expenses incurred in defending a proceeding in advance of its final
disposition conferred in this Section 10.02 shall not be exclusive of any other
right which any person may have or hereafter acquire under any statute,
provision of the Restated Certificate of Incorporation, By-law, agreement, vote
of stockholders or disinterested Directors or otherwise. No repeal or
modification of this Article shall in any way diminish or adversely affect the
rights of any Director, officer, employee or agent of the Corporation hereunder
in respect of any occurrence or matter arising prior to any such repeal or
modification.

        (d)     Insurance. The Corporation may maintain insurance, at its
expense, to protect itself and any Director, officer, employee or agent of the
Corporation or another corporation, partnership, joint venture, trust or other
enterprise against any such expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under the DGCL.

        (e)     Severability. If any provision or provisions of this Article X
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality and enforceability of the remaining provisions of
this Article X (including, without limitation, each portion of any paragraph of
this Article X containing any such provision held to be invalid, illegal or
unenforceable, that is not itself held to be invalid, illegal or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article X (including, without
limitation, each such portion of any paragraph of this Article X containing any
such provision held to be invalid, illegal or unenforceable) shall be construed
so as to give effect to the intent manifested by the provision held invalid,
illegal or unenforceable.

                                   ARTICLE XI
                             Section 203 of the DGCL

        SECTION 11.01. The Corporation hereby elects not to be governed by
Section 203 of the DGCL.<PAGE>   1

                          RIGHTS AGREEMENT (the "Agreement"), dated as of March
                 26, 2001, between AGERE SYSTEMS INC., a Delaware corporation
                 (the "Company"), and THE BANK OF NEW YORK, as Rights Agent (the
                 "Rights Agent").

                The board of directors of the Company (the "Board of Directors")
has authorized and declared a dividend of one Class B Right (as hereinafter
defined) for each share of Class B Common Stock, par value $.01 per share, (the
"Class B Common Stock") of the Company outstanding on March 27, 2001 (the
"Record Date"), and has further authorized and directed the issuance of one
Class A Right (as hereinafter defined) and one Class B Right (the Class A Rights
and Class B Rights together, the "Rights") (subject to adjustment as provided
herein) with respect to each share of Class A Common Stock, par value $.01 per
share, (the "Class A Common Stock"), and Class B Common Stock, respectively,
that shall become outstanding between the Record Date and the earlier of the
Distribution Date and the Expiration Date (as such terms are hereinafter
defined); provided, however, that Rights may be issued with respect to Common
Shares (as hereinafter defined) that shall become outstanding after the
Distribution Date and prior to the Expiration Date in accordance with Section
22.

                Accordingly, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

                SECTION 1.      Certain Definitions. For purposes of this
Agreement, the following terms have the meanings indicated:

<PAGE>   6

                                                                               2

                (a)     "Acquiring Person" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of (A) 10% or more of the shares of Class A Common Stock then
outstanding, (B) 10% or more of the shares of Class B Common Stock then
outstanding, or (C) Common Shares which have the right to cast 10% or more of
the votes that may be cast by all outstanding shares for the election of
directors of the Company, but shall not include (i) the Company, any Subsidiary
of the Company, any employee benefit or compensation plan of the Company or of
any Subsidiary of the Company, or any Person holding Common Shares for or
pursuant to the terms of any such plan, or prior to the Spinoff Date, any Lucent
Entity (each, an "Exempt Person") or (ii) any such Person who has become and is
the Beneficial Owner of shares of capital stock of the Company that meet the
requirements set forth in (A), (B), or (C) solely as a result of (AA) the
acquisition by such Person or one or more of its Affiliates or Associates of
Beneficial Ownership of additional Common Shares if such acquisition was made in
the good faith belief that such acquisition would not (x) cause the Beneficial
Ownership by such Person, together with its Affiliates and Associates, to meet
the requirements set forth in (A), (B), or (C) at the time of such acquisition
and such good faith belief was based on the good faith reliance on information
contained in publicly filed reports or documents of the Company that are
inaccurate or out-of-date or (y) otherwise cause a Distribution Date or the
adjustment provided for in Section 11(a) to occur or (BB) the acquisition by
such Person or one or more of its Affiliates or Associates of Beneficial
Ownership of additional Common Shares of the Company if the Board of Directors
determines that such acquisition was made in good faith without the knowledge by
such Person or Affiliates or Associates that such Person would thereby become an
Acquiring Person, which determination of the Board of Directors shall be
conclusive and binding on such Person, the Rights Agent, the holders of the
Rights and all other Persons. Notwithstanding the foregoing, if any Person that
is not an Acquiring Person due to (ii)(AA) or (ii)(BB) of the prior sentence
does not reduce its percentage of Beneficial Ownership of Common Shares of the
Company to less than that which meets the requirements set forth in (A), (B), or
(C) by the Close of Business on the tenth calendar day after notice from the
Company (the date of notice being the first day) that such Person's Beneficial
Ownership of Common Shares would make it an Acquiring Person, such Person

<PAGE>   7
                                                                               3

shall, at the end of such ten calendar day period, become an Acquiring Person
(and such clause (ii)(AA) or (ii)(BB) shall no longer apply to such Person). For
purposes of this definition, the determination whether any Person acted in "good
faith" shall be conclusively determined by the Board of Directors.
Notwithstanding anything in this definition of Acquiring Person to the contrary,
no Person shall become an "Acquiring Person" as the result of an acquisition of
Common Shares by the Company which, by reducing the number of shares
outstanding, increases the proportionate number of shares beneficially owned by
such Person to that which meets the requirements set forth in (A), (B), or (C);
provided, however, that if a Person shall become the Beneficial Owner of Common
Shares that meet the requirements set forth in (A), (B), or (C) by reason of
share acquisitions by the Company and shall, after such share acquisitions by
the Company, become the Beneficial owner of any additional Common Shares of the
Company (other than pursuant to a dividend or distribution paid or made by the
Company on the outstanding Common Shares or pursuant to a split or subdivision
of the outstanding Common Shares), then such Person shall be deemed to be an
"Acquiring Person" unless upon becoming the Beneficial Owner of such additional
Common Shares such Person does not beneficially own Common Shares that meet the
requirements set forth in (A), (B), or (C).

                (b)     "Affiliate" shall have the meaning ascribed to such term
in Rule 12b-2 of the General Rules and Regulations under the Exchange Act as in
effect on the date of this Agreement.

                (c)     "Associate" shall have the meaning ascribed to such term
in Rule 12b-2 of the General Rules and Regulations under the Exchange Act as in
effect on the date of this Agreement.

                (d)     (i) A Person shall be deemed the "Beneficial Owner" of
and shall be deemed to "beneficially own" any securities:

                (A)     which such Person or any of such Person's Affiliates or
        Associates beneficially owns, directly or indirectly;

                (B)     which such Person or any of such Person's Affiliates or
        Associates has (1) the right to acquire (whether such right is
        exercisable immediately or only

<PAGE>   8
                                                                               4

        after the passage of time) pursuant to any agreement, arrangement or
        understanding (other than customary agreements with and between
        underwriters and selling group members with respect to a bona fide
        public offering of securities), or upon the exercise of conversion
        rights, exchange rights, rights (other than these Rights), warrants or
        options, or otherwise; provided, however, that a Person shall not be
        deemed the Beneficial Owner of, or to beneficially own, securities
        tendered pursuant to a tender or exchange offer made by or on behalf of
        such Person or any of such Person's Affiliates or Associates until such
        tendered securities are accepted for purchase or exchange; or (2) the
        right to vote, or the right to direct the vote, pursuant to any
        agreement, arrangement or understanding; provided, however, that a
        Person shall not be deemed the Beneficial Owner of, or to beneficially
        own, any security, if the agreement, arrangement or understanding to
        vote, or direct the vote of, such security (x) arises solely from a
        revocable proxy or consent given to such Person in response to a public
        proxy or consent solicitation made pursuant to, and in accordance with,
        the applicable rules and regulations promulgated under the Exchange Act
        and (y) is not also then reportable on Schedule 13D under the Exchange
        Act (or any comparable or successor report); or

                (C)     which are beneficially owned, directly or indirectly, by
        any other Person with which such Person or any of such Person's
        Affiliates or Associates has any agreement, arrangement or understanding
        (other than customary agreements with and between underwriters and
        selling group members with respect to a bona fide public offering of
        securities) for the purpose of acquiring, holding, voting (except to the
        extent contemplated by the proviso to Section 1(d)(i)(B)(2)) or
        disposing of such securities of the Company provided, however, that no
        Person who is an officer, director or employee of an Exempt Person shall
        be deemed, solely by reason of such Person's status or authority as
        such, to be the "Beneficial Owner" of, to have "Beneficial Ownership" of
        or to "beneficially own" any securities that are "beneficially owned"
        (as defined in this Section 1(d)), including, without limitation, in a
        fiduciary capacity, by an Exempt

<PAGE>   9
                                                                               5

        Person or by any other such officer, director or employee of an Exempt
        Person.

                (ii)    Notwithstanding anything in this definition of
Beneficial Ownership to the contrary (A) no Person (and no Affiliate or
Associate of any Person) shall at any time prior to the Spinoff Date be deemed
to be the "Beneficial Owner" of or to "beneficially own" any securities if such
Person is the Beneficial Owner of or "beneficially owns" such securities as a
result of one or more agreements, arrangements or understandings with any Lucent
Entity (whether or not the Company or any other Person is a party thereto) and
if such Person would not be the Beneficial Owner of or "beneficially own" such
securities if such agreements, arrangements or understandings were not then in
effect and (B) the phrase "then outstanding", when used with reference to a
Person's Beneficial Ownership of securities of the Company, shall mean the
number of such securities then issued and outstanding together with the number
of such securities not then actually issued and outstanding which such Person
would be deemed to own beneficially hereunder.

                (e)     "Board of Directors" shall have the meaning set forth in
the preamble hereof.

                (f)     "Business Day" shall mean any day other than a Saturday,
a Sunday, or a day on which banking institutions in New York are authorized or
obligated by law or executive order to close.

                (g)     "Book-Entry" shall mean an uncertified book-entry for
the Company's Common Stock.

                (h)     "Class A Common Stock" shall have the meaning set forth
in the preamble hereof.

                (i)     "Class A Right" shall represent the right to purchase
one one-thousandth of a Preferred Share, upon the terms and subject to the
conditions herein set forth.

                (j)     "Class A Rights Certificate" shall have the meaning set
forth in Section 3(a) hereof.

                (k)     "Class B Common Stock" shall have the meaning set forth

                (c)     Rights shall be issued in respect of all Common Shares
issued or disposed of (including, without limitation, upon disposition of Common
Shares out of treasury stock or issuance or reissuance of Common Shares out of
authorized but unissued shares) after the Record Date but prior to the earlier
of the Distribution Date and the Expiration Date (including an issuance of Class
A Common Stock upon the conversion, whether automatic or voluntary, of Class B
Common Stock into Class A Common Stock), or in certain circumstances provided in
Section 22 hereof, after the Distribution Date. Certificates for Class A Common
Stock and confirmations evidencing Book-Entries which become outstanding
(including, without limitation, reacquired Class A Common Stock referred to in
the penultimate sentence of this paragraph (c)) after the Record Date but prior
to the earliest of the Distribution Date, the Redemption Date or the Final
Expiration Date, shall also be deemed to be certificates for the associated
Class A Rights, and shall have impressed on, printed on, written on or otherwise

        This certificate also evidences and entitles the holder hereof to
        certain Class A Rights as set forth in a Rights Agreement between Agere
        Systems Inc. and The Bank of New York, dated as of March 26, 2001, as
        amended from time to time (the "Rights Agreement"), the terms of which
        are hereby incorporated herein by reference and a copy of which is on
        file at the principal executive offices of Agere Systems Inc. Under
        certain circumstances, as set forth in the Rights Agreement, such Class
        A Rights will be evidenced by separate certificates and will no longer
        be evidenced by this certificate. Agere Systems Inc. will mail to the
        holder of this certificate a copy of the Rights Agreement without charge
        after receipt of a written request therefor. Under certain
        circumstances, as set forth in the Rights Agreement, Class A Rights
        owned by or transferred to any Person who is or becomes an Acquiring
        Person (as defined in the Rights Agreement) and certain transferees
        thereof will become null and void and will no longer be transferable.

Certificates for Class B Common Stock and confirmations evidencing Book-Entries
which become outstanding (including, without limitation, reacquired Class B
Common Stock referred to in the penultimate sentence of this paragraph (c))
after the Record Date but prior to the earliest of the Distribution Date, the
Redemption Date or the Final Expiration Date, shall also be deemed to be
certificates for the associated Class B Rights, and shall have impressed on,
printed on, written on or otherwise affixed to them the following legend:

        This certificate also evidences and entitles the holder hereof to
        certain Class B Rights as set forth in a Rights Agreement between Agere
        Systems Inc. and The Bank of New York, dated as of March 26, 2001, as
        amended from time to time (the "Rights Agreement"), the terms of which
        are hereby incorporated herein by reference and a copy of which is on
        file at the principal executive offices of Agere Systems Inc. Under
        certain circumstances, as set forth in the Rights Agreement, such Class
        B Rights will be evidenced by separate certificates and will no longer
        be evidenced by this certificate. Agere Systems Inc. will mail to the
        holder of this certificate a copy of the Rights Agreement without charge
        after receipt of a written request therefor. Under certain
        circumstances, as set forth in the Rights Agreement, Class B Rights
        owned by or transferred to any Person who is or becomes an Acquiring
        Person (as defined in the Rights Agreement) and certain transferees
        thereof will become null and void and will no longer be transferable.

With respect to such certificates containing the foregoing legends, until the
Distribution Date, the Rights associated with the Common Shares represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate, except as otherwise provided
herein, shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby. In the event that the Company purchases or
otherwise acquires any Common Shares after the Record Date but prior to the
Distribution Date, any Rights associated with such Common Shares shall be deemed
canceled and retired so that the Company shall not be entitled to

                                                                              12

exercise any Rights associated with the Common Shares which are no longer
outstanding.

Notwithstanding this paragraph (c), the omission of a legend shall not affect
the enforceability of any part of this Agreement or the rights of any holder of
the Rights (other than any Acquiring Person or any Associate or Affiliate of an
Acquiring Person).

                (d)     As soon as practicable after the Distribution Date, the
Company will prepare and execute, the Rights Agent will countersign, and the
Company will send or cause to be sent (and the Rights Agent will, if requested,
send) by first-class, postage-prepaid mail, to each record holder of Common
Shares as of the Close of Business on the Distribution Date (other than any
Acquiring Person or any Associate or Affiliate of an Acquiring Person), at the
address of such holder shown on the records of the Company, a Right Certificate,
in substantially the form of Exhibit B and Exhibit C, evidencing one Right
(subject to adjustment as provided herein) for each Common Share so held. From
and after the Distribution Date, the Rights will be evidenced solely by such
Right Certificates.

                SECTION 4.      Form of Right Certificates. The Right
Certificates (and the forms of election to purchase shares and of assignment to
be printed on the reverse thereof) shall be substantially the same as Exhibit B
and Exhibit C hereto and may have such marks of identification or designation
and such legends, summaries or endorsements printed thereon as the Company may
deem appropriate and as are not inconsistent with the provisions of this
Agreement, or as may be required to comply with any applicable law or with any
rule or regulation made pursuant thereto or with any rule or regulation of any
stock exchange or automated quotation system on which the Rights may from time
to time be listed, or to conform to usage. Subject to the provisions of this
Agreement, the Right Certificates shall entitle the holders thereof to purchase
such number of one one-thousandths of a Preferred Share as shall be set forth
therein at the Purchase Price, but the number of such one one-thousandths of a
Preferred Share and the Purchase Price shall be subject to adjustment as
provided herein.

                SECTION 5.      Countersignature and Registration. The Right
Certificates shall be executed on behalf of the Company by its Chairman of the
Board, its Chief Executive

<PAGE>   17

                                                                              13

Officer, its President, any of its Vice Presidents, or its Treasurer, either
manually or by facsimile signature, shall have affixed thereto the Company's
seal or a facsimile thereof, and shall be attested by the Secretary or an
Assistant Secretary of the Company, either manually or by facsimile signature.
The Right Certificates shall be manually countersigned by the Rights Agent and
shall not be valid for any purpose unless countersigned. In case any officer of
the Company who shall have signed any of the Right Certificates shall cease to
be such officer of the Company before countersignature by the Rights Agent and
issuance and delivery by the Company, such Right Certificates, nevertheless, may
be countersigned by the Rights Agent and issued and delivered by the Company
with the same force and effect as though the individual who signed such Right
Certificates had not ceased to be such officer of the Company; and any Right
Certificate may be signed on behalf of the Company by any individual who, at the
actual date of the execution of such Right Certificate, shall be a proper
officer of the Company to sign such Right Certificate although at the date of
the execution of this Agreement any such individual was not such an officer.

                Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at its principal office, books for registration and transfer
of the Right Certificates issued hereunder. Such books shall show the names and
addresses of the respective holders of the Right Certificates, the number of
Rights evidenced on its face by each of the Right Certificates and the date of
each of the Right Certificates.

                SECTION 6.      Transfer, Split Up, Combination and Exchange of
Right Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.
Subject to the provisions of this Agreement, at any time after the Distribution
Date, and at or prior to the Close of Business on the Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become void pursuant to Section 11(a)(ii) hereof) may be
transferred, split up, combined, or exchanged for another Right Certificate or
other Right Certificates entitling the registered holder to purchase a like
number of one one-thousandths of a Preferred Share as the Right Certificate or
Right Certificates surrendered then entitled such holder to purchase. Any
registered holder desiring to transfer, split up, combine or exchange any Right
Certificate or Right Certificates shall make such request in writing delivered
to the Rights Agent, and shall surrender the Right Certificate or Right
Certificates to be transferred, split up, combined or exchanged at the principal
office of the Rights Agent. Thereupon the Rights Agent shall countersign and
deliver to the Person entitled thereto a Right

                                                                              14

Certificate or Right Certificates, as the case may be, as so requested. The
Company may require payment of a sum sufficient to cover any tax or governmental
charge that may be imposed in connection with any transfer, split up,
combination or exchange of Right Certificates.

                Subject to the provisions of this Agreement, at any time after
the Distribution Date and prior to the Expiration Date, upon receipt by the
Company and the Rights Agent of evidence reasonably satisfactory to them of the
loss, theft, destruction or mutilation of a Right Certificate, and, in case of
loss, theft or destruction, of indemnity or security reasonably satisfactory to
them, and, at the Company's request, reimbursement to the Company and the Rights
Agent of all reasonable expenses incidental thereto, and upon surrender to the
Rights Agent and cancelation of the Right Certificate if mutilated, the Company
will make and deliver a new Right Certificate of like tenor to the Rights Agent
for delivery to the registered holder in lieu of the Right Certificate so lost,
stolen, destroyed or mutilated.

                SECTION 7.      Exercise of Rights; Purchase Price; Expiration
Date of Rights. (a) Except as otherwise provided herein, the Rights shall become
exercisable on the Distribution Date, and thereafter the registered holder of
any Right Certificate may exercise the Rights evidenced thereby (except as
otherwise provided herein), in whole or in part, at any time after the
Distribution Date, upon surrender of the Right Certificate, with the form of
election to purchase on the reverse side thereof duly executed, to the Rights
Agent at the principal office of the Rights Agent, together with payment of the
Purchase Price for each one one-thousandth of a Preferred Share (or other
securities, cash or other assets, as the case may be) as to which the Rights are
exercised, at any time which is both after the Distribution Date and prior to
the time (the "Expiration Date") that is the earliest of (i) the Close of
Business on March 27, 2011 (the "Final Expiration Date"), (ii) the time at which
the Rights are redeemed as provided in Section 23 hereof (the "Redemption
Date"), or (iii) the

<PAGE>   19
                                                                              15

time at which such Rights are exchanged as provided in Section 24 hereof.

                (b)     The Purchase Price for each one one-thousandth of a
Preferred Share purchasable pursuant to the exercise of a Right shall initially
be $100.00, and the Purchase Price and the number of one one-thousandth of a
share of Preferred Share or other securities or property to be acquired upon
exercise of a Right shall be subject to adjustment from time to time as provided
in Section 11 or 13 hereof and shall be payable in lawful money of the United
States of America in accordance with paragraph (c) below.

                (c)     Except as otherwise provided herein, upon receipt of a
Right Certificate representing exercisable Rights, with the form of election to
purchase duly executed, accompanied by payment of the Purchase Price for the
shares to be purchased and an amount equal to any applicable transfer tax
required to be paid by the holder of such Right Certificate in accordance with
Section 9 hereof by certified check, cashier's check or money order payable to
the order of the Company, the Rights Agent shall thereupon promptly (i)(A)
requisition from any transfer agent of the Preferred Shares, or make available
if the Rights Agent is the transfer agent for the Preferred Shares, certificates
for the number of Preferred Shares to be purchased and the Company hereby
irrevocably authorizes any such transfer agent to comply with all such requests,
or (B) requisition from the depositary agent appointed by the Company depositary
receipts representing interests in such number of one one-thousandths of a
Preferred Share as are to be purchased (in which case certificates for the
Preferred Shares represented by such receipts shall be deposited by the transfer
agent of the Preferred Shares with such depositary agent) and the Company hereby
directs such depositary agent to comply with such request; (ii) when
appropriate, requisition from the Company the amount of cash to be paid in lieu
of issuance of fractional shares in accordance with Section 14 hereof; (iii)
promptly after receipt of such certificates or depositary receipts, cause the
same to be delivered to or upon the order of the registered holder of such Right
Certificate, registered in such name or names as may be designated by such
holder; and (iv) when appropriate, after receipt, promptly deliver such cash to
or upon the order of the registered holder of such Right Certificate.

                (d)     Except as otherwise provided herein, in case the
registered holder of any Right Certificate shall exercise less than all the
Rights evidenced thereby, a new Right Certificate evidencing Rights equivalent
to the exercisable Rights remaining unexercised shall be issued by the Rights
Agent to the registered holder of such Right Certificate or to his duly
authorized assigns, subject to the provisions of Section 14 hereof.

                (e)     Notwithstanding anything in this Agreement to the
contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder of Rights upon the
occurrence of any purported transfer or exercise of Rights pursuant to Section 6
hereof or this Section 7 unless such registered holder shall have (i) completed
and signed the certificate contained in the form of assignment or form of
election to purchase set forth on the reverse side of the Rights Certificate
surrendered for such transfer or exercise and (ii) provided such additional
evidence of the identity of the Beneficial Owner (or former Beneficial Owner)
thereof as the Company shall reasonably request.

                SECTION 8.      Cancelation and Destruction of Right
Certificates. All Right Certificates surrendered for the purpose of exercise,
transfer, split up, combination or exchange shall, if surrendered to the Company
or to any of its agents, be delivered to the Rights Agent for cancelation or in
canceled form, or, if surrendered to the Rights Agent, shall be canceled by it,
and no Right Certificates shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Agreement. The Company shall deliver
to the Rights Agent for cancelation and retirement, and the Rights Agent shall
so cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all canceled Right Certificates to the Company, or shall, at the written request
of the Company, destroy such canceled Right Certificates, and, in such case,
shall deliver a certificate of destruction thereof to the Company.

                SECTION 9.      Availability of Preferred Shares. (a) The
Company covenants and agrees that it will cause to be reserved and kept
available out of its authorized and unissued Preferred Shares or any Preferred
Shares held in

<PAGE>   21

                                                                              17

its treasury, the number of Preferred Shares that will be sufficient to permit
the exercise in full of all outstanding Rights in accordance with Section 7.

                (b)     So long as the Preferred Shares issuable upon the
exercise of Rights may be listed or admitted to trading on any national
securities exchange, or quoted on NASDAQ, the Company shall use its best efforts
to cause, from and after such time as the Rights become exercisable, all shares
reserved for such issuance to be listed or admitted to trading on such exchange,
or quoted on NASDAQ, upon official notice of issuance upon such exercise.

                (c)     From and after such time as the Rights become
exercisable, the Company shall use its best efforts, if then necessary to permit
the issuance of Preferred Shares upon the exercise of Rights, to register and
qualify such Preferred Shares under the Securities Act and any applicable state
securities or "Blue Sky" laws (to the extent exemptions therefrom are not
available), cause such registration statement and qualifications to become
effective as soon as possible after such filing and keep such registration and
qualifications effective (with a prospectus at all times meeting the
requirements of the Securities Act) until the earlier of the date as of which
the Rights are no longer exercisable for such securities and the Expiration
Date. The Company may temporarily suspend, for a period of time not to exceed 90
days, the exercisability of the Rights in order to prepare and file a
registration statement under the Securities Act and permit it to become
effective. Upon any such suspension, the Company shall issue a public
announcement stating that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement at such time as the suspension is no
longer in effect. Notwithstanding any provision of this Agreement to the
contrary, the Rights shall not be exercisable in any jurisdiction unless the
requisite qualification in such jurisdiction shall have been obtained and until
a registration statement under the Securities Act shall have been declared
effective, unless an exemption therefrom is available.

                (d)     The Company covenants and agrees that it will take all
such action as may be necessary to ensure that all Preferred Shares delivered
upon exercise of Rights shall, at the time of delivery of the certificates for
such Preferred Shares (subject to payment of the Purchase Price), be duly

<PAGE>   22

                                                                              18

and validly authorized and issued and fully paid and nonassessable shares.

                The Company further covenants and agrees that it will pay when
due and payable any and all federal and state transfer taxes and charges which
may be payable in respect of the issuance or delivery of the Right Certificates
or of any Preferred Shares upon the exercise of Rights. The Company shall not,
however, be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of Right Certificates to a Person other than, or the
issuance or delivery of certificates or depositary receipts for the Preferred
Shares in a name other than that of, the registered holder of the Right
Certificate evidencing Rights surrendered for exercise or to issue or to deliver
any certificates or depositary receipts for Preferred Shares upon the exercise
of any Rights until any such tax shall have been paid (any such tax being
payable by the holder of such Right Certificate at the time of surrender) or
until it has been established to the Company's reasonable satisfaction that no
such tax is due.

                SECTION 10.     Preferred Shares Record Date. Each Person in
whose name any certificate for Preferred Shares is issued upon the exercise of
Rights shall for all purposes be deemed to have become the holder of record of
the Preferred Shares represented thereby on, and such certificate shall be
dated, the date upon which the Right Certificate evidencing such Rights was duly
surrendered and payment of the Purchase Price (and any applicable transfer
taxes) was made; provided, however, that if the date of such surrender and
payment is a date upon which the Preferred Shares transfer books of the Company
are closed, such Person shall be deemed to have become the record holder of such
shares on, and such certificate shall be dated, the next succeeding Business Day
on which the Preferred Shares transfer books of the Company are open. Prior to
the exercise of the Rights evidenced thereby, the holder of a Right Certificate
shall not be entitled to any rights of a holder of Preferred Shares for which
the Rights shall be exercisable, including, without limitation, the right to
vote, to receive dividends or other distributions or to exercise any preemptive
rights, and shall not be entitled to receive any notice of any proceedings of
the Company, except as provided herein.

                SECTION 11.     Adjustment of Purchase Price, Number and Kind of
Shares or Number of Rights. The Purchase Price,

<PAGE>   23
                                                                              19

the number of Preferred Shares or other securities or property purchasable upon
exercise of each Right and the number of Rights outstanding are subject to
adjustment from time to time as provided in this Section 11.

                (a)     (i) In the event the Company shall at any time after the
date of this Agreement (A) declare and pay a dividend on the Preferred Shares
payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C)
combine the outstanding Preferred Shares into a smaller number of Preferred
Shares or (D) issue any shares of its capital stock in a reclassification of the
Preferred Shares (including any such reclassification in connection with a
consolidation or merger in which the Company is the continuing or surviving
corporation), except as otherwise provided in this Section 11(a), the number and
kind of shares of capital stock issuable upon exercise of a Right at the time of
the record date for such dividend or of the effective date of such subdivision,
combination or reclassification shall be proportionately adjusted so that the
holder of any Right exercised after such time shall be entitled to receive the
aggregate number and kind of shares of capital stock which, if such Right had
been exercised immediately prior to such date and at a time when the Preferred
Shares transfer books of the Company were open, he would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification; provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right.

                (ii)    Subject to Section 24 of this Agreement, in the event
        any Person becomes an Acquiring Person, each holder of a Class A Right
        and each holder of a Class B Right, respectively, except as otherwise
        provided in this Agreement, shall thereafter have a right to receive,
        upon exercise thereof at a price equal to the then current Purchase
        Price multiplied by the number of one one-thousandths of a Preferred
        Share for which a Right is then exercisable, in accordance with the
        terms of this Agreement and in lieu (in both cases) of Preferred Shares,
        such number of shares of Class A Common Stock and Class B Common Stock,
        respectively, of the Company as shall equal the result obtained by (A)
        multiplying the then current Purchase Price by the number of one
        one-thousandths of a Preferred Share for

<PAGE>   24

                                                                              20

        which a Right is then exercisable and dividing that product by (B) 50%
        of the then Current Per Share Market Price of such class of Common
        Shares (determined pursuant to Section 11(d)(i) hereof) for which a
        Right is exercisable on the date of the occurrence of such event
        provided, however, that the Purchase Price and the number of Common
        Shares so receivable upon exercise of a Right shall, following the time
        a Person becomes an Acquiring Person, be subject to further adjustment
        as appropriate in accordance with Section 11(f) hereof. The Company
        agrees that, after the earlier of the Distribution Date or the Shares
        Acquisition Date, it will not, except as permitted by Sections 23, 24 or
        27 hereof, take (or permit any Subsidiary to take) any action if at the
        time such action is taken it is reasonably foreseeable that such action
        will diminish substantially or eliminate the benefits intended to be
        afforded by the Rights.

                Notwithstanding anything in this Agreement to the contrary, from
and after the occurrence of such event, any Rights that are or were acquired or
beneficially owned by (x) any Acquiring Person (or any Associate or Affiliate of
such Acquiring Person), (y) a transferee of any Acquiring Person (or any such
Affiliate or Associate) who becomes a transferee after a Person becomes an
Acquiring Person or (z) a transferee of any Acquiring Person (or any such
Affiliate or Associate) who became a transferee prior to or concurrently with a
Person becoming an Acquiring Person pursuant to either (I) a transfer from the
Acquiring Person to holders of its equity securities or to any Person with whom
it has any continuing agreement, arrangement or understanding regarding the
transferred Rights or (II) a transfer which the Board of Directors has
determined is part of a plan, arrangement or understanding which has the purpose
or effect of avoiding the provisions of this paragraph, and subsequent
transferees of such Persons, shall be void and any holder of such Rights shall
thereafter have no right to exercise such Rights under any provision of this
Agreement. The Company shall use all reasonable efforts to ensure that the
provisions of this Section 11(a)(ii) are complied with, but shall have no
liability to any holder of Right Certificates or other Person as a result of its
failure to make any determinations with respect to an Acquiring Person or its
Affiliates, Associates or transferees hereunder. From and after the time a
Person becomes an Acquiring Person, no Right Certificate shall be

<PAGE>   25

                                                                              21

issued pursuant to Section 3 or Section 6 hereof that represents Rights that are
or have become void pursuant to the provisions of this paragraph, and any Right
Certificate delivered to the Rights Agent that represents Rights that are or
have become void pursuant to the provisions of this paragraph shall be canceled.
From and after the occurrence of an event specified in Section 13(a) hereof, any
Rights that theretofore have not been exercised pursuant to this Section
11(a)(ii) shall thereafter be exercisable only in accordance with Section 13 and
not pursuant to this Section 11(a)(ii).

                (iii)   The Company may at its option substitute for a Common
        Share issuable upon the exercise of Rights in accordance with the
        foregoing subparagraph (ii) a number of Preferred Shares or fraction
        thereof such that the current per share market price of one Preferred
        Share multiplied by such number or fraction is equal to the Current Per
        Share Market Price of such Common Share. In the event that there shall
        not be sufficient Class A Common Stock or Class B Common Stock issued
        but not outstanding or authorized but unissued to permit the exercise in
        full of the Rights in accordance with the foregoing subparagraph (ii),
        the Board of Directors shall, with respect to such deficiency, to the
        extent permitted by applicable law and any material agreements then in
        effect to which the Company is a party, (A) determine the excess (such
        excess, the "Spread") of (1) the value of the Class A Common Stock or
        Class B Common Stock, as the case may be, issuable upon the exercise of
        a Right in accordance with the foregoing subparagraph (ii) (the "Current
        Value") over (2) the Purchase Price (as adjusted in accordance with the
        foregoing subparagraph (ii)), and (B) with respect to each Class A Right
        or Class B Right, as the case may be (other than Rights which have
        become void pursuant to the foregoing subparagraph (ii)), make adequate
        provision to substitute for the Common Shares issuable in accordance
        with the foregoing subparagraph (ii) upon exercise of the Right and
        payment of the Purchase Price (as adjusted in accordance therewith), (1)
        cash, (2) a reduction in such Purchase Price, (3) Preferred Shares or
        other equity securities of the Company (including, without limitation,
        shares or fractions of shares of preferred

<PAGE>   26

                                                                              22

        stock which, by virtue of having dividend, voting and liquidation rights
        substantially comparable to those of the Class A Common Stock or Class B
        Common Stock, as the case may be, are deemed in good faith by the Board
        of Directors to have substantially the same value as the Common Shares
        (such Preferred Shares and shares or fractions of shares of preferred
        stock are hereinafter referred to as "Common Stock Equivalents")), (4)
        debt securities of the Company, (5) other assets, or (6) any combination
        of the foregoing, having a value which, when added to the value of the
        Common Shares issued upon exercise of such Right, shall have an
        aggregate value equal to the Current Value (less the amount of any
        reduction in such Purchase Price), where such aggregate value has been
        determined by the Board of Directors upon the advice of a nationally
        recognized investment banking firm selected in good faith by the Board
        of Directors; provided, however, that if the Company shall not make
        adequate provision to deliver value pursuant to clause (B) above within
        thirty (30) days following the time a Person becomes an Acquiring Person
        (the time a Person becomes an Acquiring Person being the "Section
        11(a)(ii) Trigger Date"), then the Company shall be obligated to
        deliver, to the extent permitted by applicable law and any material
        agreements then in effect to which the Company is a party, upon the
        surrender for exercise of a Right and without requiring payment of such
        Purchase Price, Class A Common Stock or Class B Common Stock, as the
        case may be (to the extent available), and then, if necessary, such
        number or fractions of Preferred Shares (to the extent available) and
        then, if necessary, cash or shares of the other class of Common Shares,
        which shares (of the class of Common Stock for which a Right is
        exercisable, Preferred Shares and/or the other class of Common Stock)
        and/or cash have an aggregate value equal to the Spread. If, upon the
        occurrence of a Person becoming an Acquiring Person, the Board of
        Directors shall determine in good faith that it is likely that
        sufficient additional shares of Class A Common Stock and/or Class B
        Common Stock, as the case may be, could be authorized for issuance upon
        exercise in full of the Rights, then, if the Board of Directors so
        elects, the thirty (30) day period set forth above may be extended to
        the extent necessary, but not more than ninety (90) days after the
        Section 11(a)(ii) Trigger Date, in order that the Company may seek

<PAGE>   27

                                                                              23

        stockholder approval for the authorization of such additional shares
        (such thirty (30) day period, as it may be extended, is herein called
        the "Substitution Period"). To the extent that the Company determines
        that some action need be taken pursuant to the second and/or third
        sentence of this Section 11(a)(iii), the Company (x) shall provide,
        subject to Section 11(a)(ii) hereof and the last sentence of this
        Section 11(a)(iii) hereof, that such action shall apply uniformly to all
        outstanding Rights and (y) may suspend the exercisability of the Rights
        until the expiration of the Substitution Period in order to seek any
        authorization of additional shares and/or to decide the appropriate form
        of distribution to be made pursuant to such second sentence and to
        determine the value thereof. In the event of any such suspension, the
        Company shall issue a public announcement stating that the
        exercisability of the Rights has been temporarily suspended, as well as
        a public announcement at such time as the suspension is no longer in
        effect. For purposes of this Section 11(a)(iii), the value of Common
        Shares shall be the Current Per Share Market Price (as determined
        pursuant to Section 11(d)(i)) on the Section 11(a)(ii) Trigger Date and
        the per share or fractional value of any "Common Stock Equivalent" shall
        be deemed to equal the current per share market price of the Common
        Shares. The Board of Directors of the Company may, but shall not be
        required to, establish procedures to allocate the right to receive
        Common Shares upon the exercise of the Rights among holders of Rights
        pursuant to this Section 11(a)(iii).

                (b)     In case the Company shall fix a record date for the
issuance of rights, options or warrants to all holders of Preferred Shares
entitling them (for a period expiring within 45 calendar days after such record
date) to subscribe for or purchase Preferred Shares (or shares having the same
rights, privileges and preferences as the Preferred Shares ("equivalent
preferred shares")) or securities convertible into Preferred Shares or
equivalent preferred shares at a price per Preferred Share or equivalent
preferred share (or having a conversion price per share, if a security
convertible into Preferred Shares or equivalent preferred shares) less than the
then Current Per Share Market Price of the Preferred Shares) on such record
date, the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in

<PAGE>   28

                                                                              24

effect immediately prior to such record date by a fraction, the numerator of
which shall be the number of Preferred Shares and equivalent preferred shares
outstanding on such record date plus the number of Preferred Shares and
equivalent preferred shares which the aggregate offering price of the total
number of Preferred Shares and/or equivalent preferred shares so to be offered
(and/or the aggregate initial conversion price of the convertible securities so
to be offered) would purchase at such current market price and the denominator
of which shall be the number of Preferred Shares and equivalent preferred shares
outstanding on such record date plus the number of additional Preferred Shares
and/or equivalent preferred shares to be offered for subscription or purchase
(or into which the convertible securities so to be offered are initially
convertible); provided, however, that in no event shall the consideration to be
paid upon the exercise of one Right be less than the aggregate par value of the
shares of capital stock of the Company issuable upon exercise of one Right. In
case such subscription price may be paid in a consideration part or all of which
shall be in a form other than cash, the value of such consideration shall be as
determined in good faith by the Board of Directors, whose determination shall be
described in a statement filed with the Rights Agent and shall be binding on the
Rights Agent and holders of the Rights. Preferred Shares and equivalent
preferred shares owned by or held for the account of the Company shall not be
deemed outstanding for the purpose of any such computation. Such adjustment
shall be made successively whenever such a record date is fixed; and in the
event that such rights, options or warrants are not so issued, the Purchase
Price shall be adjusted to be the Purchase Price which would then be in effect
if such record date had not been fixed.

                (c)     In case the Company shall fix a record date for the
making of a distribution to all holders of the Preferred Shares (including any
such distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription rights or warrants (excluding those referred
to in Section 11(b) hereof), the Purchase Price to be in effect after such
record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which

<PAGE>   29

                                                                              25

shall be the then Current Per Share Market Price of the Preferred Shares on such
record date, less the fair market value (as determined in good faith by the
Board of Directors, whose determination shall be described in a statement filed
with the Rights Agent and shall be binding on the Rights Agent and holders of
the Rights) of the portion of the assets or evidences of indebtedness so to be
distributed or of such subscription rights or warrants applicable to one
Preferred Share and the denominator of which shall be such Current Per Share
Market Price of the Preferred Shares; provided, however, that in no event shall
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company to be issued
upon exercise of one Right. Such adjustments shall be made successively whenever
such a record date is fixed; and in the event that such distribution is not so
made, the Purchase Price shall again be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

                (d)     (i) For the purpose of any computation hereunder, the
"Current Per Share Market Price" of any security (a "Security" for the purpose
of this Section 11(d)(i)) on any date shall be deemed to be the average of the
daily closing prices per share of such Security for the 30 consecutive Trading
Days immediately prior to such date; provided, however, that in the event that
the Current Per Share Market Price of the Security is determined during a period
following the announcement by the issuer of such Security of (A) a dividend or
distribution on such Security payable in shares of such Security or securities
convertible into such shares, or (B) any subdivision, combination or
reclassification of such Security and prior to the expiration of 30 Trading Days
after the ex-dividend date for such dividend or distribution, or the record date
for such subdivision, combination or reclassification, then, and in each such
case, the Current Per Share Market Price shall be appropriately adjusted to
reflect the current market price per share equivalent of such Security. The
closing price for each day shall be the last sale price, regular way, or, in
case no such sale takes place on such day, the average of the closing bid and
asked prices, regular way, in either case, as reported in the principal
consolidated transaction reporting system with respect to securities listed or
admitted to trading on the New York Stock Exchange or, if the Security is not
listed or admitted to trading on the New

<PAGE>   30

                                                                              26

York Stock Exchange, as reported in the principal consolidated transaction
reporting system with respect to securities listed on the principal national
securities exchange on which the Security is listed or admitted to trading or,
if the Security is not listed or admitted to trading on any national securities
exchange, the last quoted price or, if not so quoted, the average of the high
bid and low asked prices in the over-the counter market, as reported on the
Nasdaq National Market or such other system then in use, or, if on any such date
the of Security is not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Security selected by the Board of Directors. The term "Trading
Day" shall mean a day on which the principal national securities exchange on
which the Security is listed or admitted to trading is open for the transaction
of business or, if the Security is not listed or admitted to trading on any
national securities exchange, a Business Day.

                (ii)    For the purpose of any computation hereunder, the
        "Current Per Share Market Price" of the Preferred Shares shall be
        determined in accordance with the method set forth in Section 11(d)(i).
        If the Preferred Shares are not publicly traded, the "Current Per Share
        Market Price" of the Preferred Shares shall be conclusively deemed to be
        the Current Per Share Market Price of the Common Shares as determined
        pursuant to Section 11(d)(i) (appropriately adjusted to reflect any
        stock split, stock dividend or similar transaction occurring after the
        date hereof), multiplied by one thousand. If neither the Common Shares
        nor the Preferred Shares are publicly held or so listed or traded,
        "Current Per Share Market Price" shall mean the fair value per share as
        determined in good faith by the Board of Directors, whose determination
        shall be described in a statement filed with the Rights Agent and shall
        be binding on the Rights Agent and the holders of the Rights.

                (e)     No adjustment in the Purchase Price shall be required
unless such adjustment would require an increase or decrease of at least 1% in
the Purchase Price; provided, however, that any adjustments which by reason of
this Section 11(e) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this
Section 11 shall be made to the

<PAGE>   31

                                                                              27

nearest cent or to the nearest one one-millionth of a Preferred Share or one
ten-thousandth of any other share or security as the case may be.
Notwithstanding the first sentence of this Section 11(e), any adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
years from the date of the transaction which requires such adjustment or (ii)
the Expiration Date.

                (f)     If as a result of an adjustment made pursuant to
Section 11(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive any shares of capital stock of the Company other than
Preferred Shares, thereafter the Purchase Price and the number of such other
shares so receivable upon exercise of any Right shall be subject to adjustment
from time to time in a manner and on terms as nearly equivalent as practicable
to the provisions with respect to the Preferred Shares contained in Section
11(a) through (c), inclusive, 11(h), 11(i) and 11(m) and the provisions of
Sections 7, 9, 10, 13 and 14 with respect to the Preferred Shares shall apply on
like terms to any such other shares.

                (g)     All Rights originally issued by the Company subsequent
to any adjustment made to the Purchase Price hereunder shall evidence the right
to purchase, at the adjusted Purchase Price, the number of one one-thousandths
of a Preferred Share purchasable from time to time hereunder upon exercise of
the Rights, all subject to further adjustment as provided herein.

                (h)     Unless the Company shall have exercised its election as
provided in Section 11(i), upon each adjustment of the Purchase Price as a
result of the calculations made in Sections 11(b) and (c), each Right
outstanding immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
one one-thousandths of a Preferred Share (calculated to the nearest one
one-millionth of a Preferred Share) obtained by (A) multiplying (x) the number
of one one-thousandths of a share covered by a Right immediately prior to this
adjustment by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (B) dividing the product so obtained by the
Purchase Price in effect immediately after such adjustment of the Purchase
Price.

<PAGE>   32

                                                                              28

                (i)     The Company may elect on or after the date of any
adjustment of the Purchase Price pursuant to Sections 11(b) or 11(c) hereof to
adjust the number of Rights in substitution for any adjustment in the number of
one one-thousandths of a Preferred Share purchasable upon the exercise of a
Right. Each of the Rights outstanding after such adjustment of the number of
Rights shall be exercisable for the number of one one-thousandths of a Preferred
Share for which a Right was exercisable immediately prior to such adjustment.
Each Right held of record prior to such adjustment of the number of Rights shall
become that number of Rights (calculated to the nearest one ten-thousandth)
obtained by dividing the Purchase Price in effect immediately prior to
adjustment of the Purchase Price by the Purchase Price in effect immediately
after adjustment of the Purchase Price. The Company shall make a public
announcement of its election to adjust the number of Rights, indicating the
record date for the adjustment, and, if known at the time, the amount of the
adjustment to be made. This record date may be the date on which the Purchase
Price is adjusted or any day thereafter, but, if the Right Certificates have
been issued, shall be at least 10 days later than the date of the public
announcement. If Right Certificates have been issued, upon each adjustment of
the number of Rights pursuant to this Section 11(i), the Company shall, as
promptly as practicable, cause to be distributed to holders of record of Right
Certificates on such record date Right Certificates evidencing, subject to
Section 14 hereof, the additional Rights to which such holders shall be entitled
as a result of such adjustment, or, at the option of the Company, shall cause to
be distributed to such holders of record in substitution and replacement for the
Right Certificates held by such holders prior to the date of adjustment, and
upon surrender thereof, if required by the Company, new Right Certificates
evidencing all the Rights to which such holders shall be entitled after such
adjustment. Right Certificates so to be distributed shall be issued, executed
and countersigned in the manner provided for herein and shall be registered in
the names of the holders of record of Right Certificates on the record date
specified in the public announcement.

                (j)     Irrespective of any adjustment or change in the Purchase
Price or the number of one one-thousandths of a Preferred Share issuable upon
the exercise of the Rights, the Right Certificates theretofore and thereafter

                                                                              29

continue to express the Purchase Price and the number of one one-thousandths of
a Preferred Share which were expressed in the initial Right Certificates issued
hereunder.

                (k)     Before taking any action that would cause an adjustment
reducing the Purchase Price below the then par value, if any, of the fractional
Preferred Share or other shares of capital stock issuable upon exercise of the
Rights, the Company shall take any corporate action which may, in the opinion of
its counsel, be necessary in order that the Company may validly and legally
issue fully paid and nonassessable Preferred Shares or such other shares at such
adjusted Purchase Price.

                (l)     In any case in which this Section 11 shall require that
an adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuing to the holder of any Right exercised after such record date of
the Preferred Shares and other capital stock or securities of the Company, if
any, issuable upon such exercise over and above the Preferred Shares and other
capital stock or securities of the Company, if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to such adjustment; provided,
however, that the Company shall deliver to such holder a due bill or other
appropriate instrument evidencing such holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.

                (m)     Anything in this Section 11 to the contrary
notwithstanding, the Company shall be entitled to make such adjustments in the
Purchase Price, in addition to those adjustments expressly required by this
Section 11, as and to the extent that it, in its sole discretion, shall
determine to be advisable in order that any consolidation or subdivision of the
Preferred Shares, issuance wholly for cash of any Preferred Shares at less than
the current market price, issuance wholly for cash of Preferred Shares or
securities which by their terms are convertible into or exchangeable for
Preferred Shares, dividends on Preferred Shares payable in Preferred Shares or
issuance of rights, options or warrants referred to hereinabove in Section
11(b), hereafter made by the Company to holders of its Preferred Shares shall
not be taxable to such stockholders.

                                                                              30

                (n)     Anything in this Agreement to the contrary
notwithstanding, in the event that at any time after the date of this Agreement
and prior to the Distribution Date, the Company shall (i) declare or pay any
dividend on the Common Shares payable in Common Shares, or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common Shares, then in each such case (A) the
number of one one-thousandths of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying the number
of one one-thousandths of a Preferred Share so purchasable immediately prior to
such event by a fraction, the numerator of which is the number of Common Shares
outstanding immediately before such event and the denominator of which is the
number of Common Shares outstanding immediately after such event, and (B) each
Common Share outstanding immediately after such event shall have issued with
respect to it that number of Rights which each Common Share outstanding
immediately prior to such event had issued with respect to it. The adjustments
provided for in this Section 11(n) shall be made successively whenever such a
dividend is declared or paid or such a subdivision, combination or consolidation
is effected.

                SECTION 12.     Certificate of Adjusted Purchase Price or Number
of Shares. Whenever an adjustment is made as provided in Section 11 or 13
hereof, the Company shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares a copy of such certificate and (c) mail a brief
summary thereof to each holder of a Right Certificate in accordance with Section
25 hereof (if so required under Section 25 hereof).

                SECTION 13.     Consolidation, Merger or Sale or Transfer of
Assets or Earning Power. (a) In the event, directly or indirectly, at any time
after a Person has become an Acquiring Person, (i) the Company shall consolidate
with, or merge with and into, any other Person, (ii) any Person shall
consolidate with the Company, or merge with and into the Company and the Company
shall be the continuing or surviving corporation of such merger and, in

<PAGE>   35

                                                                              31

connection with such merger, all or part of the Common Shares shall be changed
into or exchanged for stock or other securities of any other Person (or the
Company) or cash or any other property, or (iii) the Company shall sell or
otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise
transfer), in one or more transactions, assets or earning power aggregating 50%
or more of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any other Person other than the Company or one or more of
its wholly owned Subsidiaries (except, prior to the Spinoff Date in the case of
each of (i), (ii) and (iii) above, where such other Person is a Lucent Entity),
then, and upon the first occurrence of such event, proper provision shall be
made so that (A) each holder of a Right (except as otherwise provided herein)
shall thereafter have the right to receive, upon the exercise thereof at a price
equal to the then current Purchase Price multiplied by the number of one
one-thousandths of a Preferred Share for which a Right is then exercisable, in
accordance with the terms of this Agreement and in lieu of Preferred Shares or
Common Shares of the Company, such number of Common Shares of such other Person
(including the Company as successor thereto or as the surviving corporation) as
shall equal the result obtained by (1) multiplying the then current Purchase
Price by the number of one one-thousandths of a Preferred Share for which a
Right is then exercisable and dividing that product by (2) 50% of the then
Current Per Share Market Price of the Common Shares of such other Person
(determined pursuant to Section 11(d) hereof) on the date of consummation of
such consolidation, merger, sale or transfer, provided, however, that the
Purchase Price (as theretofore adjusted) and the number of Common Shares of such
other Person so receivable upon exercise of a Right shall be subject to further
adjustment as appropriate in accordance with Section 11(f) hereof to reflect any
events occurring in respect of the Common Shares of such other Person after the
occurrence of such consolidation, merger, sale or transfer; (B) the issuer of
such Common Shares shall thereafter be liable for, and shall assume, by virtue
of such consolidation, merger, sale or transfer, all the obligations and duties
of the Company pursuant to this Agreement; (C) the term "Company" shall
thereafter be deemed to refer to such issuer; and (D) such issuer shall take
such steps (including, but not limited to, the reservation of a sufficient
number of its Common Shares in accordance with Section 9 hereof) in connection
with such consummation as may be necessary to assure that the

<PAGE>   36

                                                                              32

provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to the Common Shares thereafter deliverable upon the exercise of
the Rights; provided that, upon the subsequent occurrence of any consolidation,
merger, sale or transfer of assets or other extraordinary transaction in respect
of such other Person, each holder of a Right shall thereupon be entitled to
receive, upon exercise of a Right and payment of the Purchase Price as provided
in this Section 13(a), such cash, shares, rights, warrants and other property
which such holder would have been entitled to receive had such holder, at the
time of such transaction, owned the Common Shares of the other Person receivable
upon the exercise of a Right pursuant to this Section 13(a), and such other
Person shall take such steps (including, but not limited to, reservation of
shares of stock) as may be necessary to permit the subsequent exercise of the
Rights in accordance with the terms hereof for such cash, shares, rights,
warrants and other property.

                (b)     The other Person referred to in Section 13(a) (the
"Principal Party") shall mean:

                (i)     in the case of any transaction described in (i) or (ii)
        of the first sentence of Section 13(a) hereof: (A) the Person that is
        the issuer of the securities into which the Common Shares are converted
        in such merger or consolidation, or, if there is more than one such
        issuer, the issuer the Common Shares of which have the greatest
        aggregate market value of shares outstanding, or (B) if no securities
        are so issued, (x) the Person that is the other party to the merger, if
        such Person survives said merger, or, if there is more than one such
        Person, the Person the Common Shares of which have the greatest
        aggregate market value of shares outstanding or (y) if the Person that
        is the other party to the merger does not survive the merger, the Person
        that does survive the merger (including the Company if it survives) or
        (z) the Person resulting from the consolidation; and

                (ii)    in the case of any transaction described in (iii) of the
        first sentence of Section 13(a) hereof, the Person that is the party
        receiving the greatest portion of the assets or earning power
        transferred pursuant to such transaction or transactions, or, if each
        Person that is a party to such transaction or

<PAGE>   37

                                                                              33

        transactions receives the same portion of the assets or earning power so
        transferred or if the Person receiving the greatest portion of the
        assets or earning power cannot be determined, whichever of such Persons
        is the issuer of Common Shares having the greatest aggregate market
        value of shares outstanding;

provided, however, that in any such case described in the foregoing clause
(b)(i) or (b)(ii), if the Common Shares of such Person are not at such time or
has not been continuously over the preceding 12-month period registered under
Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect
Subsidiary of another Person the Common Shares of which are and have been so
registered, the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person,
the Common Shares of all of which are and have been so registered, the term
"Principal Party" shall refer to whichever of such Persons is the issuer of
Common Shares having the greatest aggregate market value of shares outstanding,
or (3) if such Person is owned, directly or indirectly, by a joint venture
formed by two or more Persons that are not owned, directly or indirectly, by the
same Person, the rules set forth in clauses (1) and (2) above shall apply to
each of the owners having an interest in the venture as if the Person owned by
the joint venture was a Subsidiary of both or all of such joint venturers, and
the Principal Party in each such case shall bear the obligations set forth in
this Section 13 in the same ratio as its interest in such Person bears to the
total of such interests.

                (c)     The Company shall not consummate any such consolidation,
merger, sale or transfer unless prior thereto the Company and such issuer shall
have executed and delivered to the Rights Agent an agreement confirming that the
requirements of Sections 13(a) and (b) hereof shall promptly be performed in
accordance with their terms and that such consolidation, merger, sale or
transfer of assets shall not result in a default by the Principal Party under
this Agreement as the same shall have been assumed by the Principal Party
pursuant to Sections 13(a) and (b) hereof and providing that, as soon as
practicable after executing such agreement pursuant to this Section 13, the
Principal Party will:

                                                                              34

                (i)     prepare and file a registration statement under the
        Securities Act, if necessary, with respect to the Rights and the
        securities purchasable upon exercise of the Rights on an appropriate
        form, use its best efforts to cause such registration statement to
        become effective as soon as practicable after such filing and use its
        best efforts to cause such registration statement to remain effective
        (with a prospectus at all times meeting the requirements of the
        Securities Act) until the Expiration Date and similarly comply with
        applicable state securities laws;

                (ii)    use its best efforts, if the Common Shares of the
        Principal Party shall be listed or admitted to trading on the New York
        Stock Exchange or on another national securities exchange, to list or
        admit to trading (or continue the listing of) the Rights and the
        securities purchasable upon exercise of the Rights on the New York Stock
        Exchange or such securities exchange, or, if the Common Shares of the
        Principal Party shall not be listed or admitted to trading on the New
        York Stock Exchange or a national securities exchange, to cause the
        Rights and the securities receivable upon exercise of the Rights to be
        authorized for quotation on NASDAQ or on such other system then in use;

                (iii)   deliver to holders of the Rights historical financial
        statements for the Principal Party which comply in all respects with the
        requirements for registration on Form 10 (or any successor form) under
        the Exchange Act; and

                (iv)    obtain waivers of any rights of first refusal or
        preemptive rights in respect of the Common Shares of the Principal Party
        subject to purchase upon exercise of outstanding Rights.

                (d)     In case the Principal Party has a provision in any of
its authorized securities or in its certificate of incorporation or by-laws or
other instrument governing its affairs, which provision would have the effect of
(i) causing such Principal Party to issue (other than to holders of Rights
pursuant to this Section 13), in connection with, or as a consequence of, the
consummation of a transaction referred to in this Section 13, Common Shares or
Common Stock Equivalents of such Principal Party at less than the

<PAGE>   39

                                                                              35

then current market price per share thereof (determined pursuant to Section
11(d) hereof) or securities exercisable for, or convertible into, Common Shares
or Common Stock Equivalents of such Principal Party at less than such then
current market price, or (ii) providing for any special payment, tax or similar
provision in connection with the issuance of the Common Shares of such Principal
Party pursuant to the provisions of Section 13, then, in such event, the Company
hereby agrees with each holder of Rights that it shall not consummate any such
transaction unless prior thereto the Company and such Principal Party shall have
executed and delivered to the Rights Agent a supplemental agreement providing
that the provision in question of such Principal Party shall have been canceled,
waived or amended, or that the authorized securities shall be redeemed, so that
the applicable provision will have no effect in connection with, or as a
consequence of, the consummation of the proposed transaction. The Company shall
not enter into any transaction of the kind referred to in this Section 13 (i) if
at the time of or immediately after such transaction there are any rights,
warrants, instruments or other instruments or securities outstanding or any
agreements or arrangements which would eliminate or substantially diminish the
benefits intended to be afforded by the Rights,(ii) prior to, simultaneously
with or immediately after such consolidation, merger, sale, transfer or other
transaction, the stockholders of the Person who constitutes, or would
constitute, the Principal Party for purposes of Section 13(b) hereof shall have
received a distribution of Rights previously owned by such Person or any of its
Affiliates or Associates or (iii) the form or nature of organization of the
Principal Party would preclude or limit the exercisability of the Rights. The
provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers.

                SECTION 14.     Fractional Rights and Fractional Shares. (a) The
Company shall not be required to issue fractions of Rights or to distribute
Right Certificates which evidence fractional Rights. In lieu of such fractional
Rights, there shall be paid to the registered holders of the Class A Rights
Certificates or the Class B Rights Certificates, as the case may be, with regard
to which such fractional Rights would otherwise be issuable, an amount in cash
equal to the same fraction of the current market value of a whole Class A Right
or Class B Right, as the case may be. For the purposes of this Section 14(a),

<PAGE>   40

                                                                              36

the current market value of a whole Right shall be the closing price of the
Rights for the Trading Day immediately prior to the date on which such
fractional Rights would have been otherwise issuable. The closing price of the
Class A Rights and the Class B Rights, as the case may be, for any day shall be
the last sale price, regular way, or, in case no such sale takes place on such
day, the average of the closing bid and asked prices, regular way, in either
case, as reported in the principal consolidated transaction reporting system
with respect to securities listed or admitted to trading on the New York Stock
Exchange or, if the Rights are not listed or admitted to trading on the New York
Stock Exchange, as reported in the principal consolidated transaction reporting
system with respect to securities listed on the principal national securities
exchange on which the Rights are listed or admitted to trading or, if the Rights
are not listed or admitted to trading on any national securities exchange, the
last quoted price or, if not so quoted, the average of the high bid and low
asked prices in the over-the-counter market, as reported on the Nasdaq National
Market or such other system then in use or, if on any such date the Rights are
not quoted by any such organization, the average of the closing bid and asked
prices as furnished by a professional market maker making a market in the Rights
selected by the Board of Directors. If on any such date no such market maker is
making a market in the Rights, the fair value of the Rights on such date as
determined in good faith by the Board of Directors shall be used.

                (b)     The Company shall not be required to issue fractions of
Preferred Shares (other than fractions which are integral multiples of one
one-thousandth of a Preferred Share) upon exercise or exchange of the Rights or
to distribute certificates which evidence fractional Preferred Shares (other
than fractions which are integral multiples of one one-thousandth of a Preferred
Share). Interests in fractions of Preferred Shares in integral multiples of one
one-thousandth of a Preferred Share may, at the election of the Company, be
evidenced by depositary receipts, pursuant to an appropriate agreement between
the Company and a depositary selected by it; provided that such agreement shall
provide that the holders of such depositary receipts shall have all the rights,
privileges and preferences to which they are entitled as beneficial owners of
the Preferred Shares represented by such depositary receipts. In lieu of
fractional Preferred Shares that are not integral

<PAGE>   41

                                                                              37

multiples of one one-thousandth of a Preferred Share, the Company shall pay to
the registered holders of Right Certificates at the time such Rights are
exercised as herein provided an amount in cash equal to the same fraction of the
current market value of one Preferred Share. For the purposes of this Section
14(b), the current market value of a Preferred Share shall be the closing price
of a Preferred Share (as determined pursuant to the second sentence of Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of such
exercise or exchange.

                (c)     The Company shall not be required to issue fractional
Common Shares or to distribute certificates which evidence fractional Common
Shares upon the exercise or exchange of Rights. In lieu of such fractional
Common Shares, the Company shall pay to the registered holders of the Right
Certificates with regard to which such fractional Common Shares would otherwise
be issuable an amount in cash equal to the same fraction of the current market
value of the applicable class of a whole Common Share (as determined in
accordance with Section 14(a) hereof) for the Trading Day immediately prior to
the date of such exercise or exchange.

                (d)     The holder of a Right by the acceptance of the Right
expressly waives his right to receive any fractional Rights or any fractional
shares upon exercise or exchange of a Right (except as provided above).

                SECTION 15.     Rights of Action. All rights of action in
respect of this Agreement, excepting the rights of action given to the Rights
Agent under Section 18 hereof, are vested in the respective registered holders
of the Right Certificates (and, prior to the Distribution Date, the registered
holders of the Common Shares); and any registered holder of any Right
Certificate (or, prior to the Distribution Date, of the Common Shares), without
the consent of the Rights Agent or of the holder of any other Right Certificate
(or, prior to the Distribution Date, of the Common Shares), may, in his own
behalf and for his own benefit, enforce, and may institute and maintain any
suit, action or proceeding against the Company to enforce, or otherwise act in
respect of, his right to exercise the Rights evidenced by such Right Certificate
(or, prior to the Distribution Date, such Common Shares) in the manner provided
in therein and in this Agreement. Without limiting the foregoing or any remedies
available to the holders of

<PAGE>   42

                                                                              38

Rights, it is specifically acknowledged that the holders of Rights would not
have an adequate remedy at law for any breach of this Agreement and will be
entitled to specific performance of the obligations under, and injunctive relief
against actual or threatened violations of the obligations of any Person subject
to, this Agreement.

                SECTION 16.     Agreement of Right Holders. Every holder of
Right, by accepting the same, consents and agrees with the Company and the
Rights Agent and with every other holder of a Right that:

                (a)     prior to the Distribution Date, the Rights will be
transferable only in connection with the transfer of the Common Shares;

                (b)     after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the principal office of the Rights Agent, duly endorsed or accompanied by a
proper instrument of transfer; and

                (c)     the Company and the Rights Agent may deem and treat the
person in whose name the Right Certificate (or, prior to the Distribution Date,
the associated Common Shares certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Right Certificate or the associated Common Shares
certificate made by anyone other than the Company or the Rights Agent) for all
purposes whatsoever, and neither the Company nor the Rights Agent, subject to
Section 7(e) hereof, shall be affected by any notice to the contrary.

                SECTION 17.     Right Certificate Holder Not Deemed a
Stockholder. No holder, as such, of any Right Certificate shall be entitled to
vote, receive dividends or be deemed for any purpose the holder of the Preferred
Shares or any other securities of the Company which may at any time be issuable
on the exercise or exchange of the Rights represented thereby, nor shall
anything contained herein or in any Right Certificate be construed to confer
upon the holder of any Right Certificate, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting stockholders (except as

<PAGE>   43

                                                                              39

provided in this Agreement), or to receive dividends or subscription rights, or
otherwise, until the Right or Rights evidenced by such Right Certificate shall
have been exercised or exchanged in accordance with the provisions hereof.

                SECTION 18.     Concerning the Rights Agent. The Company agrees
to pay to the Rights Agent reasonable compensation for all services rendered by
it hereunder and, from time to time, on demand of the Rights Agent, its
reasonable expenses and counsel fees and other disbursements incurred in the
administration and execution of this Agreement and the exercise and performance
of its duties hereunder. The Company also agrees to indemnify the Rights Agent
for, and to hold it harmless against, any loss, liability, or expense incurred
without negligence, bad faith or willful misconduct on the part of the Rights
Agent, for anything done or omitted by the Rights Agent in connection with the
acceptance and administration of this Agreement, including the costs and
expenses of defending against any claim of liability in the premises. The
provisions of this Section shall survive the termination of this Agreement.

                The Rights Agent shall be protected and shall incur no liability
for, or in respect of any action taken, suffered or omitted by it in connection
with, its administration of this Agreement in reliance upon any Right
Certificate or certificate for the Preferred Shares or Common Shares or for
other securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement, or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by
the proper Person or Persons, or otherwise upon the advice of counsel as set
forth in Section 20 hereof.

                SECTION 19.     Merger or Consolidation or Change of Name of
Rights Agent. Any corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any corporation succeeding to
the stock transfer or corporate trust powers of the Rights Agent or any
successor Rights Agent, shall be the successor to the Rights Agent under this
Agreement without the execution or filing of any paper or

<PAGE>   44

                                                                              40

any further act on the part of any of the parties hereto; provided that such
corporation would be eligible for appointment as a successor Rights Agent under
the provisions of Section 21 hereof. In case at the time such successor Rights
Agent shall succeed to the agency created by this Agreement, any of the Right
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the countersignature of the predecessor Rights Agent and
deliver such Right Certificates so countersigned; and, in case at that time any
of the Right Certificates shall not have been countersigned, any successor
Rights Agent may countersign such Right Certificates either in the name of the
predecessor Rights Agent or in the name of the successor Rights Agent; and in
all such cases such Right Certificates shall have the full force provided in the
Right Certificates and in this Agreement.

                In case at any time the name of the Rights Agent shall be
changed and at such time any of the Right Certificates shall have been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Right Certificates so countersigned; and in
case at that time any of the Right Certificates shall not have been
countersigned, the Rights Agent may countersign such Right Certificates either
in its prior name or in its changed name; and in all such cases such Right
Certificates shall have the full force provided in the Right Certificates and in
this Agreement.

                SECTION 20.     Duties of Rights Agent. The Rights Agent
undertakes the duties and obligations imposed by this Agreement upon the
following terms and conditions, by all of which the Company and the holders of
Right Certificates, by their acceptance thereof, shall be bound:

                (a)     The Rights Agent may consult with legal counsel (who may
be legal counsel for the Company), and the opinion of such counsel shall be full
and complete authorization and protection to the Rights Agent as to any action
taken or omitted by it in good faith and in accordance with such opinion.

                (b)     Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter be proved or established by the Company prior to taking or suffering any

                                                                              41

action hereunder, such fact or matter (unless other evidence in respect thereof
be herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, the President, any Vice President, the Treasurer or the
Secretary of the Company and delivered to the Rights Agent; and such certificate
shall be full authorization to the Rights Agent for any action taken or suffered
in good faith by it under the provisions of this Agreement in reliance upon such
certificate.

                (c)     The Rights Agent shall be liable hereunder to the
Company and any other Person only for its own negligence, bad faith or willful
misconduct; provided, however, that the Rights Agent shall in no event be liable
or responsible for any indirect, consequential, special or punitive damages.

                (d)     The Rights Agent shall not be liable for or by reason of
any of the statements of fact or recitals contained in this Agreement or in the
Right Certificates (except its countersignature thereof) or be required to
verify the same, but all such statements and recitals are and shall be deemed to
have been made by the Company only.

                (e)     The Rights Agent shall not be under any responsibility
in respect of the validity of this Agreement or the execution and delivery
hereof (except the due execution hereof by the Rights Agent) or in respect of
the validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Right Certificate;
nor shall it be responsible for any change in the exercisability of the Rights
(including the Rights becoming void pursuant to Section 11(a)(ii) hereof) or any
adjustment in the terms of the Rights (including the manner, method or amount
thereof) provided for in Section 3, 11, 13, 23 or 24, or the ascertaining of the
existence of facts that would require any such change or adjustment (except with
respect to the exercise of Rights evidenced by Right Certificates after actual
notice that such change or adjustment is required); nor shall it by any act
hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any

<PAGE>   46

                                                                              42

Preferred Shares to be issued pursuant to this Agreement or any Right
Certificate or as to whether any Preferred Shares will, when issued, be validly
authorized and issued, fully paid and nonassessable.

                (f)     The Company agrees that it will perform, execute,
acknowledge and deliver or cause to be performed, executed, acknowledged and
delivered all such further and other acts, instruments and assurances as may
reasonably be required by the Rights Agent for the carrying out or performing by
the Rights Agent of the provisions of this Agreement.

                (g)     The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from
any one of the Chairman of the Board, the Chief Executive Officer, the
President, any Vice President, the Secretary or the Treasurer of the Company,
and to apply to such officers for advice or instructions in connection with its
duties, and it shall not be liable for any action taken or suffered by it in
good faith in accordance with instructions of any such officer or for any delay
in acting while waiting for those instructions.

                (h)     The Rights Agent and any stockholder, director, officer
or employee of the Rights Agent may buy, sell or deal in any of the Rights or
other securities of the Company or become pecuniarily interested in any
transaction in which the Company may be interested, or contract with or lend
money to the Company or otherwise act as fully and freely as though it were not
Rights Agent under this Agreement. Nothing herein shall preclude the Rights
Agent from acting in any other capacity for the Company or for any other legal
entity.

                (i)     The Rights Agent may execute and exercise any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through its attorneys or agents, and the Rights Agent shall not be
answerable or accountable for any act, default, neglect or misconduct of any
such attorneys or agents or for any loss to the Company resulting from any such
act, default, neglect or misconduct, provided reasonable care was exercised in
the selection and continued employment thereof.

                (j)     If, with respect to any Rights Certificate surrendered
to the Rights Agent for exercise or transfer, the certificate contained in the
form of assignment or the

<PAGE>   47

                                                                            43

form of election to purchase set forth on the reverse thereof, as the case may
be, has not been completed to certify the holder is not an Acquiring Person (or
an Affiliate or Associate thereof) or a transferee thereof, the Rights Agent
shall not take any further action with respect to such requested exercise or
transfer without first consulting with the Company.

                SECTION 21.     Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Shares or Preferred Shares by registered or
certified mail, and, following the Distribution Date, to the holders of the
Right Certificates by first-class mail. The Company may remove the Rights Agent
or any successor Rights Agent upon 30 days' notice in writing, mailed to the
Rights Agent or successor Rights Agent, as the case may be, and to each transfer
agent of the Common Shares or Preferred Shares by registered or certified mail,
and, following the Distribution Date, to the holders of the Right Certificates
by first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company shall fail to make such appointment within a
period of 30 days after giving notice of such removal or after it has been
notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Right Certificate (who shall,
with such notice, submit his Right Certificate for inspection by the Company),
then the registered holder of any Right Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be a
corporation organized and doing business under the laws of the United States or
of the State of New York (or of any other state of the United States so long as
such corporation is authorized to do business as a banking institution in the
State of New York, in good standing, having an office in the State of New York,
which is authorized under such laws to exercise corporate trust or stock
transfer powers and is subject to supervision or examination by federal or state
authority and which has at the time of its appointment as Rights Agent a
combined capital and surplus of at least $50 million. After appointment, the
successor Rights Agent shall be vested with the same powers, rights, duties and
responsibilities as if

<PAGE>   48

                                                                              44

it had been originally named as Rights Agent without further act or deed; but
the predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Shares or Preferred Shares, and, following the Distribution Date,
mail a notice thereof in writing to the registered holders of the Right
Certificates. Failure to give any notice provided for in this Section 21,
however, or any defect therein, shall not affect the legality or validity of the
resignation or removal of the Rights Agent or the appointment of the successor
Rights Agent, as the case may be.

                SECTION 22.     Issuance of New Right Certificates.
Notwithstanding any of the provisions of this Agreement or of the Rights to the
contrary, the Company may, at its option, issue new Right Certificates
evidencing Rights in such form as may be approved by the Board of Directors to
reflect any adjustment or change in the Purchase Price and the number or kind or
class of shares or other securities or property purchasable under the Right
Certificates made in accordance with the provisions of this Agreement. In
addition, in connection with the issuance or sale of Common Shares following the
Distribution Date and prior to the Expiration Date, the Company may with respect
to Common Shares so issued or sold pursuant to (i) the exercise of stock
options, (ii) under any employee plan or arrangement, (iii) upon the exercise,
conversion or exchange of securities, notes or debentures issued by the Company,
or (iv) a contractual obligation of the Company, in each case existing prior to
the Distribution Date, issue Rights Certificates representing the appropriate
number and class of Rights in connection with such issuance or sale; provided,
however, that (i) no such Right Certificate shall be issued if, and to the
extent that, the Company shall be advised by counsel that such issuance would
create a significant risk of material adverse tax consequences to the Company or
the Person to whom such Right Certificate would be issued, (ii) no such Right
Certificate shall be issued if, and to the extent that, appropriate adjustment
shall otherwise have been made in lieu of the issuance thereof and (iii) no such
Right Certificate shall be issued in respect of Rights that have become void
pursuant to the terms

<PAGE>   49

                                                                              45

hereof.

                SECTION 23.     Redemption. (a) The Board of Directors may, at
its option, at any time prior to such time as any Person becomes an Acquiring
Person, redeem all but not less than all the then outstanding Rights at a
redemption price of $.01 per Right, appropriately adjusted to reflect any stock
split, stock dividend or similar transaction occurring in respect of the Common
Shares after the date hereof (such redemption price being hereinafter referred
to as the "Redemption Price"). The redemption of the Rights may be made
effective at such time, on such basis and with such conditions as the Board of
Directors, in its sole discretion, may establish. The Redemption Price shall be
payable, at the option of the Company, in cash, Common Shares, or such other
form of consideration as the Board of Directors shall determine.

                (b)     Immediately upon the action of the Board of Directors
ordering the redemption of the Rights pursuant to paragraph (a) of this Section
23 (or at such later time as the Board of Directors may establish for the
effectiveness of such redemption), and without any further action and without
any notice, the right to exercise the Rights will terminate and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price.
The Company shall promptly give public notice of any such redemption; provided,
however, that the failure to give, or any defect in, any such notice shall not
affect the validity of such redemption. Within 10 days after such action of the
Board of Directors ordering the redemption of the Rights (or at such later time
as the Board of Directors may establish for the effectiveness of such
redemption), the Company shall mail a notice of redemption to all the holders of
the then outstanding Rights at their last addresses as they appear upon the
registry books of the Rights Agent or, prior to the Distribution Date, on the
registry books of the transfer agent for the Common Shares. Any notice which is
mailed in the manner herein provided shall be deemed given, whether or not the
holder receives the notice. Each such notice of redemption will state the method
by which the payment of the Redemption Price will be made. Neither the Company
nor any of its Affiliates or Associates may redeem, acquire or purchase for
value any Rights at any time in any manner other than that specifically set
forth in this Section 23 or in Section 24 hereof, and other than in connection
with the acquisition of Common Shares prior to the Distribution Date.

<PAGE>   50

                                                                              46

                SECTION 24.     Exchange. (a) The Board of Directors may, at its
option, at any time after any Person becomes an Acquiring Person, exchange all
or part of the then outstanding and exercisable Rights (which shall not include
Rights that have become void pursuant to the provisions of Section 11(a)(ii)
hereof) for Common Shares at an exchange ratio of one share of Class A Common
Stock and one share of Class B Common Stock per Class A Right and Class B Right,
respectively, appropriately adjusted to reflect any stock split, stock dividend
or similar transaction occurring in respect of the Common Shares after the date
hereof (such exchange ratio being hereinafter referred to as the "Exchange
Ratio"). Notwithstanding the foregoing, the Board of Directors shall not be
empowered to effect such exchange at any time after any Person (other than the
Company, any Subsidiary of the Company, any employee benefit plan of the Company
or of any Subsidiary of the Company or any entity holding Common Shares for or
pursuant to the terms of any such plan or, prior to the Spinoff Date, any Lucent
Entity), together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 50% or more of the Common Shares then outstanding. From and
after the occurrence of an event specified in Section 13(a) hereof, any Rights
that theretofore have not been exchanged pursuant to this Section 24(a) shall
thereafter be exercisable only in accordance with Section 13 and may not be
exchanged pursuant to this Section 24(a). The exchange of the Rights by the
Board of Directors may be made effective at such time, on such basis and with
such conditions as the Board of Directors in its sole discretion may establish.

                (b)     Immediately upon the effectiveness of the action of the
Board of Directors ordering the exchange of any Rights pursuant to paragraph (a)
of this Section 24 and without any further action and without any notice, the
right to exercise such Rights shall terminate and the only right thereafter of a
holder of such Rights shall be to receive that number of shares of Class A
Common Stock or Class B Common Stock equal to the number of such Class A Rights
or Class B Rights, as the case may be, held by such holder multiplied by the
Exchange Ratio. The Company shall promptly give public notice of any such
exchange; provided, however, that the failure to give, or any defect in, such
notice shall not affect the validity of such exchange. The Company promptly
shall mail a notice of any such exchange to

<PAGE>   51

                                                                              47

all of the holders of such Rights at their last addresses as they appear upon
the registry books of the Rights Agent. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of exchange will state the method by which the exchange
of the Common Shares for Rights will be effected and, in the event of any
partial exchange, the number of Rights which will be exchanged. Any partial
exchange shall be effected pro rata based on the number of Rights (other than
Rights which have become void pursuant to the provisions of Section 11(a)(ii)
hereof) held by each holder of Rights.

                (c)     The Company may at its option substitute and, in the
event that there shall not be sufficient Common Shares issued but not
outstanding or authorized but unissued to permit any exchange of Rights as
contemplated in accordance with this Section 24, the Company shall substitute to
the extent of such insufficiency, for each Common Share that would otherwise be
issuable upon exchange of a Right, a number of Preferred Shares or fraction
thereof (or equivalent preferred shares) such that the Current Per Share Market
Price of one Preferred Share (or equivalent preferred share) multiplied by such
number or fraction is equal to the Current Per Share Market Price of one share
of Class A Common Stock or Class B Common Stock, as the case may be, as of the
date of issuance of such Preferred Shares (or equivalent preferred share) or
fraction thereof.

                (d)     The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional Common
Shares. In lieu of such fractional Common Shares, the Company shall pay to the
registered holders of the Right Certificates with regard to which such
fractional Common Shares would otherwise be issuable an amount in cash equal to
the same fraction of the current market value of a whole share of Class A Common
Stock or Class B Common Stock, as the case may be. For the purposes of this
paragraph (d), the current market value of a whole share of Class A Common Stock
or Class B Common Stock, as the case may be, shall be the closing price of a
share of Class A Common Stock or Class B Common Stock, as the case may be (as
determined pursuant to the second sentence of Section 11(d)(i) hereof) for the
Trading Day immediately prior to the date of exchange pursuant to this Section
24.

                SECTION 25.     Notice of Certain Events. (a) In case the
Company shall at any time after the earlier of the Distribution Date or the
Shares Acquisition Date propose (i) to pay any dividend payable in stock of any
class to the holders of its Preferred Shares or to make any other distribution
to the holders of its Preferred Shares (other than a regular quarterly cash
dividend), (ii) to offer to the holders of its Preferred Shares rights or
warrants to subscribe for or to purchase any additional Preferred Shares or
shares of stock of any class or any other securities, rights or options, (iii)
to effect any reclassification of its Preferred Shares (other than a
reclassification involving only the subdivision of outstanding Preferred
Shares), (iv) to effect any consolidation or merger into or with, or to effect
any sale or other transfer (or to permit one or more of its Subsidiaries to
effect any sale or other transfer), in one or more transactions, of 50% or more
of the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to, any other Person, (v) to effect the liquidation, dissolution or
winding up of the Company, or (vi) to declare or pay any dividend on the Common
Shares payable in Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or otherwise than by
payment of dividends in Common Shares), then, in each such case, the Company
shall give to each holder of a Right Certificate, in accordance with Section 26
hereof, a notice of such proposed action, which shall specify the record date
for the purposes of such stock dividend, or distribution of rights or warrants,
or the date on which such reclassification, consolidation, merger, sale,
transfer, liquidation, dissolution, subdivision or winding up is to take place
and the date of participation therein by the holders of the Common Shares and/or
Preferred Shares, if any such date is to be fixed, and such notice shall be so
given in the case of any action covered by clause (i) or (ii) above at least 10
days prior to the record date for determining holders of the Preferred Shares
for purposes of such action, and in the case of any such other action, at least
10 days prior to the date of the taking of such proposed action or the date of
participation therein by the holders of the Common Shares and/or Preferred
Shares, whichever shall be the earlier; provided, that, prior to the
Distribution Date, any notice in regard to a declaration or payment of any
dividend on the Common Shares payable in Common Shares or to effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of

<PAGE>   53

                                                                              49

dividends in Common Shares) shall be adequately given if given within a
reasonable time after the issuance date for such stock dividend or effective
date of such subdivision, combination or consolidation.

                (b)     In case the event set forth in Section 11(a)(ii) or
Section 13 hereof shall occur, then the Company shall as soon as practicable
thereafter give to each holder of a Right Certificate (or if occurring prior to
the Distribution Date, the holders of the Common Shares), in accordance with
Section 26 hereof, a notice of the occurrence of such event, which notice shall
describe such event and the consequences of such event to holders of Rights
under Section 11(a)(ii) and Section 13 hereof.

                SECTION 26.     Notices. Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of any Right
Certificate to or on the Company shall be sufficiently given or made if sent by
first-class mail, postage prepaid, addressed (until another address is filed in
writing with the Rights Agent) as follows:

                SECTION 27.     Supplements and Amendments. At any time prior to
the time any person becomes an Acquiring Person, and subject to the last
sentence of this Section 27, the Company may, and the Rights Agent shall if the
Company so directs, supplement or amend any provision of this Agreement in any
manner which the Company may deem necessary or desirable (including the date on
which the Expiration Date or the Distribution Date shall occur, the amount of
the Purchase Price, the definition of "Acquiring Person" or the time during
which the Rights may be redeemed pursuant to Section 23) without the approval of
any holder of Rights. From and after the time any Person becomes an Acquiring
Person, and subject to applicable law and the last sentence of this Section 27,
the Company may, and the Rights Agent shall if the Company so directs, amend
this Agreement without the approval of any holders of Rights (a) to cure any
ambiguity or to correct or supplement any provision contained herein which may
be defective or inconsistent with any other provision of this Agreement or (b)
to otherwise change or supplement any other provisions in this Agreement in any
matter which the Company may deem necessary or desirable and which in each such
case shall not (i) adversely affect the interests of the holders of Rights as
such (other than an Acquiring Person or an Affiliate or Associate of an
Acquiring Person), (ii) cause this Agreement again to become amendable other
than in accordance with this sentence or (iii) cause the Rights again to become
redeemable. Any supplement or amendment to this Agreement duly approved by the
Company that does not amend Section 19, 20 or 21 in a manner adverse to the
Rights Agent shall become effective immediately upon execution by the Company,
whether or not also executed by the Rights Agent. In addition, notwithstanding
anything to the contrary contained in this Rights Agreement, no supplement or
amendment to this Rights Agreement shall be made which reduces the Redemption
Price (except as required by Section 11(a)(i)). In connection with any
supplement or amendment to this Agreement, the Company shall deliver to the
Rights Agent a certificate certifying that such supplement or amendment complies
with the terms of the preceding sentence.

                SECTION 28.     Successors. All the covenants and provisions of
this Agreement by or for the benefit of the Company or the Rights Agent shall
bind and inure to the benefit of their respective successors and assigns
hereunder.

                SECTION 29.     Benefits of this Agreement. Nothing in this
Agreement shall be construed to give to any Person other than the Company, the
Rights Agent and the registered holders of the Right Certificates (and, prior to
the Distribution Date, the Common Shares) any legal or equitable right, remedy
or claim under this Agreement; but this Agreement shall be for the sole and
exclusive benefit of the Company, the Rights Agent and the registered holders of

                SECTION 30.     Severability. If any term, provision, covenant
or restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

                SECTION 31.     Governing Law; Jurisdiction; Waiver of Jury
Trial. This Agreement and each Right Certificate issued hereunder shall be
deemed to be a contract made under the laws of the State of Delaware and for all
purposes shall be governed by and construed in accordance with the laws of such
State applicable to contracts to be made and performed entirely within such
State; provided, however, that the rights, duties and obligations of the Rights
Agent shall be governed and construed in accordance with the laws of the State
of New York. The parties agree that all actions and proceedings arising out of
this Agreement or any of the transactions contemplated hereby, shall be brought
in the United States District Court for the Southern District of New York or in
a New York State Court in the County of New York and that in connection with any
such action or proceeding, submit to the jurisdiction of and venue in, such

        (Pursuant to Section 151 of the Delaware General Corporation Law)

                          ----------------------------

                Agere Systems Inc., a corporation organized and existing under
the General Corporation Law of the State of Delaware (hereinafter called the
"Corporation"), hereby certifies that the following resolution was adopted by
the Board of Directors of the Corporation as required by Section 151 of the
General Corporation Law on March 27, 2001:

                RESOLVED, that pursuant to the authority granted to and vested
in the Board of Directors in accordance with the provisions of its Restated
Certificate of Incorporation, the Board of Directors hereby creates a series of
Preferred Stock, par value $1.00 per share, of the Corporation and hereby states
the designation and number of shares, and fixes the relative rights, preferences
and limitations thereof (in addition to the provisions set forth in the Restated
Certificate of Incorporation of the Corporation, which are applicable to the
Preferred Stock of all classes and series), as set forth in the Certificate of
Designations comprising Exhibit A to the Rights Agreement, which is attached
hereto and incorporated herein by reference.

                Series A Junior Participating Preferred Stock:

                Section 1.      Designation and Amount. The shares of such
series shall be designated as "Series A Junior Participating Preferred Stock"
(the "Series A Preferred Stock") and the number of shares constituting the
Series A

<PAGE>   58
                                                                               2

Preferred Stock shall be 11,500,000. Such number of shares may be increased or
decreased by resolution of the Board of Directors; provided that no decrease
shall reduce the number of shares of Series A Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the exercise of outstanding options, rights or warrants or
upon the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.

                Section 2.      Dividends and Distributions.

<PAGE>   59
                                                                               3

                (A)     Subject to the rights of the holders of any shares of
any series of Preferred Stock (or any similar stock) ranking prior and superior
to the Series A Preferred Stock with respect to dividends, the holders of shares
of Series A Preferred Stock, in preference to the holders of Common Stock, par
value $.01 per share (the "Common Stock"), of the Corporation, and of any other
junior stock, shall be entitled to receive, when, as and if declared by the
Board of Directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the first day of March, June, September and
December in each year (each such date being referred to herein as a "Quarterly
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date
after the first issuance of a share or fraction of a share of Series A Preferred
Stock, in an amount per share (rounded to the nearest cent) equal to the greater
of (a) $1 or (b) subject to the provision for adjustment hereinafter set forth,
1,000 times the aggregate per share amount of all cash dividends, and 1,000
times the aggregate per share amount (payable in kind) of all non-cash dividends
or other distributions, other than a dividend payable in shares of Class A
Common Stock par value $.01 per share or Class B Common Stock par value $.01 per
share, (the Class A Common Stock and the Class B Common Stock together the
"Common Stock") or a subdivision of the outstanding shares of Common Stock (by
reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Preferred Stock. In the event the Corporation
shall at any time after March 27, 2001 declare and pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

                (B)     The Corporation shall declare a dividend or

<PAGE>   60
                                                                               4

distribution on the Series A Preferred Stock as provided in paragraph (A) of
this Section immediately after it declares a dividend or distribution on the
Common Stock (other than a dividend payable in shares of Common Stock); provided
that, in the event no dividend or distribution shall have been declared on the
Common Stock during the period between any Quarterly Dividend Payment Date and
the next subsequent Quarterly Dividend Payment Date, a dividend of $1 per share
on the Series A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

                (C)     Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares, unless the date of
issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date, in which case dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a
Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series A Preferred Stock entitled to
receive a quarterly dividend and before such Quarterly Dividend Payment Date, in
either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Series A Preferred Stock in
an amount less than the total amount of such dividends at the time accrued and
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding. The Board of Directors may fix a
record date for the determination of holders of shares of Series A Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be not more than 60 days prior to the date
fixed for the payment thereof.

                Section 3.      Voting Rights. The holders of shares of Series A
Preferred Stock shall have the following voting rights:

<PAGE>   61
                                                                               5

                (A)     Subject to the provision for adjustment hereinafter set
forth, each share of Series A Preferred Stock shall entitle the holder thereof
to 1,000 votes on all matters submitted to a vote of the stockholders of the
Corporation. In the event the Corporation shall at any time declare or pay any
dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the number of votes per share to which holders of shares of
Series A Preferred Stock were entitled immediately prior to such event shall be
adjusted by multiplying such number by a fraction, the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                (B)     Except as otherwise provided herein, in any other
Certificate of Designations creating a series of Preferred Stock or any similar
stock, or by law, the holders of shares of Series A Preferred Stock and the
holders of shares of Common Stock and any other capital stock of the Corporation
having general voting rights shall vote together as one class on all matters
submitted to a vote of stockholders of the Corporation.

                (C)     Except as set forth herein, or as otherwise provided by
law, holders of Series A Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for taking any corporate
action.

                (D)     If, at the time of any annual meeting of stockholders
for the election of directors, the equivalent of six quarterly dividends
(whether or not consecutive) payable on any share or shares of Series A
Preferred Stock are in default, the number of directors constituting the Board
of Directors of the Corporation shall be increased by two. In addition to voting
together with the holders of Common Stock for the election of other directors of
the Corporation, the holders of record of the Series A Preferred Stock, voting
separately as a class to the exclusion of the holders of Common Stock, shall be
entitled at said meeting

<PAGE>   62
                                                                               6

of stockholders (and at each subsequent annual meeting of stockholders), unless
all dividends in arrears on the Series A Preferred Stock have been paid or
declared and set apart for payment prior thereto, to vote for the election of
two directors of the Corporation, the holders of any Series A Preferred Stock
being entitled to cast a number of votes per share of Series A Preferred Stock
as is specified in paragraph (A) of this Section 3. Each such additional
director shall not be classified, but shall serve until the next annual meeting
of stockholders for the election of directors, or until his successor shall be
elected and shall qualify, or until his right to hold such office terminates
pursuant to the provisions of this Section 3(D). Until the default in payments
of all dividends which permitted the election of said directors shall cease to
exist, any director who shall have been so elected pursuant to the provisions of
this Section 3(D) may be removed at any time, without cause, only by the
affirmative vote of the holders of the shares of Series A Preferred Stock at the
time entitled to cast a majority of the votes entitled to be cast for the
election of any such director at a special meeting of such holders called for
that purpose, and any vacancy thereby created may be filled by the vote of such
holders. If and when such default shall cease to exist, the holders of the
Series A Preferred Stock shall be divested of the foregoing special voting
rights, subject to revesting in the event of each and every subsequent like
default in payments of dividends. Upon the termination of the foregoing special
voting rights, the terms of office of all persons who may have been elected
directors pursuant to said special voting rights shall forthwith terminate, and
the number of directors constituting the Board of Directors shall be reduced by
two. The voting rights granted by this Section 3(D) shall be in addition to any
other voting rights granted to the holders of the Series A Preferred Stock in
this Section 3.

                Section 4.      Certain Restrictions.

                (A)     Whenever quarterly dividends or other dividends or
distributions payable on the Series A Preferred Stock as provided in Section 2
are in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Preferred Stock
outstanding shall have been paid in full, the Corporation shall not:

                                                                               7

                (i)     declare or pay dividends, or make any other
        distributions, on any shares of stock ranking junior (either as to
        dividends or upon liquidation, dissolution or winding up) to the Series
        A Preferred Stock;

                (ii)    declare or pay dividends, or make any other
        distributions, on any shares of stock ranking on a parity (either as to
        dividends or upon liquidation, dissolution or winding up) with the
        Series A Preferred Stock, except dividends paid ratably on the Series A
        Preferred Stock and all such parity stock on which dividends are payable
        or in arrears in proportion to the total amounts to which the holders of
        all such shares are then entitled;

                (iii)   redeem or purchase or otherwise acquire for
        consideration shares of any stock ranking junior (either as to dividends
        or upon liquidation, dissolution or winding up) to the Series A
        Preferred stock, provided that the Corporation may at any time redeem,
        purchase or otherwise acquire shares of any such junior stock in
        exchange for shares of any stock of the Corporation ranking junior
        (either as to dividends or upon dissolution, liquidation or winding up)
        to the Series A Preferred Stock; or

                (iv)    redeem or purchase or otherwise acquire for
        consideration any shares of Series A Preferred Stock, or any shares of
        stock ranking on a parity with the Series A Preferred Stock, except in
        accordance with a purchase offer made in writing or by publication (as
        determined by the Board of Directors) to all holders of such shares upon
        such terms as the Board of Directors, after consideration of the
        respective annual dividend rates and other relative rights and
        preferences of the respective series and classes, shall determine in
        good faith will result in fair and equitable treatment among the
        respective series or classes.

                (B)     The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (A) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

                Section 5.      Reacquired Shares. Any shares of

<PAGE>   64
                                                                               8

Series A Preferred Stock purchased or otherwise acquired by the Corporation in
any manner whatsoever shall be retired promptly after the acquisition thereof.
All such shares shall upon their retirement become authorized but unissued
shares of Preferred Stock and may be reissued as part of a new series of
Preferred Stock subject to the conditions and restrictions on issuance set forth
herein, in the Restated Certificate of Incorporation, or in any other
Certificate of Designations creating a series of Preferred Stock or any similar
stock or as otherwise required by law.

                Section 6.      Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received $1,000 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series A
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 1,000
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Series A Preferred Stock, except distributions made ratably on the Series A
Preferred Stock and all such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up. Neither the merger or consolidation of the
Corporation into or with another entity nor the merger or consolidation of any
other entity into or with the Corporation shall be deemed to be a liquidation,
dissolution or winding up of the Corporation within the meaning of this Section
6. In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the aggregate amount to which holders of shares of Series A Preferred
Stock were entitled immediately prior to such event under the proviso in clause

<PAGE>   65
                                                                               9

(1) of the preceding sentence shall be adjusted by multiplying such amount by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

                Section 7.      Consolidation, Merger, etc. In case the
Corporation shall enter into any consolidation, merger, combination or other
transaction in which the outstanding shares of Common Stock are exchanged for or
changed into other stock or securities, cash and/or any other property, then in
any such case each share of Series A Preferred Stock shall at the same time be
similarly exchanged or changed into an amount per share, subject to the
provision for adjustment hereinafter set forth, equal to 1,000 times the
aggregate amount of stock, securities, cash and/or any other property (payable
in kind), as the case may be, into which or for which each share of Common Stock
is changed or exchanged. In the event the Corporation shall at any time declare
or pay any dividend on the Common Stock payable in shares of Common Stock, or
effect a subdivision or combination or consolidation of the outstanding shares
of Common Stock (by reclassification or otherwise than by payment of a dividend
in shares of Common Stock) into a greater or lesser number of shares of Common
Stock, then in each such case the amount set forth in the preceding sentence
with respect to the exchange or change of shares of Series A Preferred Stock
shall be adjusted by multiplying such amount by a fraction, the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

                Section 8.      No Redemption. The shares of Series A Preferred
Stock shall not be redeemable.

                Section 9.      Ranking. The Series A Junior Participating
Preferred Stock shall rank junior to all other series of the Preferred Stock as
to the payment of dividends and as to the distribution of assets upon
liquidation, dissolution or winding up, unless the terms of any such series
shall provide otherwise, and shall rank senior to the Common Stock as to such
matters.

                Section 10.     Amendment. At any time that any

<PAGE>   66
                                                                              10

shares of Series A Preferred Stock are outstanding, the Restated Certificate of
Incorporation of the Corporation shall not be amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Series A Preferred Stock so as to affect them adversely without the affirmative
vote of the holders of at least two-thirds of the outstanding shares of Series A
Preferred Stock, voting separately as a single class.

                IN WITNESS WHEREOF, the Corporation has caused this Certificate
of Designations to be executed by its Senior Vice President and General Counsel

        UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT,
        RIGHTS OWNED BY OR TRANSFERRED TO ANY PERSON WHO IS OR BECOMES AN
        ACQUIRING PERSON (AS DEFINED IN THE RIGHTS AGREEMENT) AND CERTAIN
        TRANSFEREES THEREOF WILL BECOME NULL AND VOID AND WILL NO LONGER BE
        TRANSFERABLE.

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

                On March 27, 2001 (the "Record Date"), the Board of Directors of
Agere Systems Inc. (the "Company") declared a dividend of one Class B Right for
each outstanding share of Class B Common Stock, par value $0.01 per share, (the
"Class B Common Stock") of the Company to the stockholders of record on March
27, 2001 (the "Record Date") and authorized the issuance of one Class A Right
and one Class B Right (the Class A Rights and Class B Rights together, the
"Rights") for each share of Class A Common Stock, par value $0.01 per share,
(the "Class A Common Stock") and Class B Common Stock, respectively (the Class A
Common Stock and Class B Common Stock together, the "Common Shares"), issued
after the Record Date. The dividend is payable on March 27, 2001 to the
stockholders of record on that date. Each Right entitles the registered holder
to purchase from the Company one one-thousandth of a share of Series A Junior
Participating Preferred Stock, par value $1.00 per share, of the Company (the
"Preferred Shares") at a price of $100.00 per one one-thousandth of a Preferred
Share (the "Purchase Price"), subject to adjustment. The description and terms
of the Rights are set forth in a Rights Agreement (the "Rights Agreement")
between the Company and The Bank of New York, as Rights Agent (the "Rights
Agent").

                Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (with
certain exceptions, an "Acquiring Person") have acquired beneficial ownership of
(A) 10% or more of the shares of Class A Common Stock then outstanding, (B) 10%
or more of the shares of Class B Common Stock then outstanding, or (C) shares of
Common Stock which have the right to cast 10% or more of the votes that may be
cast by all outstanding shares for the election of directors of the Company or
(ii) such date, if any, as may be designated by the Board of Directors of the
Company following the commencement of, or first public disclosure of

<PAGE>   85
                                                                               2

an intention to commence, a tender or exchange offer for outstanding Common
Shares which could result in such person or group becoming the beneficial owner
of (A) 10% or more of the shares of Class A Common Stock then outstanding, (B)
10% or more of the shares of Class B Common Stock then outstanding, or (C)
shares of Common Shares which have the right to cast 10% or more of the votes
that may be cast by all outstanding shares for the election of directors of the
Company (the earlier of such dates being the "Distribution Date"), the Rights
will not be represented by a separate certificate, and will not be transferable
apart from the Common Stock, but will instead be evidenced, (i) with respect to
any of the shares of Common Stock held in uncertificated book-entry form (a
"Book-Entry") outstanding as of the Record Date, by such Book-Entry and (ii)
with respect to the shares of Common Stock evidenced by Common Stock
certificates outstanding as of the Record Date, by such Common Stock
certificates, together with a copy of this Summary of Rights. The Rights
Agreement contains exceptions from its operating provision for Lucent and its
affiliates and associates prior to the time it effects the distribution of all
of its shares in the Company to its stockholders.

                The Rights Agreement provides that, until the Distribution Date
(or earlier redemption or expiration of the Rights), the Rights will be
transferred with and only with the Common Shares. Until the Distribution Date
(or earlier redemption or expiration of the Rights), new Common Share
certificates issued after the Record Date upon transfer or new issuance of
Common Shares will contain a notation incorporating the Rights Agreement by
reference. Until the Distribution Date (or earlier redemption or expiration of
the Rights), the surrender for transfer of any certificates for Common Shares
outstanding as of the Record Date, even without such notation or a copy of this
Summary of Rights being attached thereto, will also constitute the transfer of
the Rights associated with the Common Shares represented by such certificate.
Until the Distribution Date (or earlier redemption or expiration of the Rights),
transfer on the Company's stock ownership records of Common Stock represented by
a Book-Entry or a certificate outstanding as the Record Date, and, in each case,
with or without a copy of this Summary of Rights attached thereto, will also
constitute the transfer of the Rights associated with the Common Stock
represented by such Book-Entry or certificate. As soon as practicable following
the Distribution Date, separate certificates evidencing the

<PAGE>   86
                                                                               3

Rights ("Right Certificates") will be mailed to holders of record of the Common
Shares as of the close of business on the Distribution Date and such separate
Right Certificates alone will evidence the Rights.

                The Rights are not exercisable until the Distribution Date. The
Rights will expire on March 27, 2011 (the "Final Expiration Date"), unless the
Final Expiration Date is advanced or extended or unless the Rights are earlier
redeemed or exchanged by the Company, in each case, as described below.

                The Purchase Price payable, and the number of Preferred Shares
or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Shares; (ii) upon the grant to holders of the Preferred Shares of
certain rights or warrants to subscribe for or purchase Preferred Shares at a
price, or securities convertible into Preferred Shares with a conversion price
less than the then-current market price of the Preferred Shares; or (iii) upon
the distribution to holders of the Preferred Shares of evidences of indebtedness
or assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings or dividends payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above).

                The number of outstanding Rights and the number of one
one-thousandths of a Preferred Share issuable upon exercise of each Right are
also subject to adjustment in the event of a stock split of the Common Shares or
a stock dividend on the Common Shares payable in Common Shares or subdivisions,
consolidations or combinations of the Common Shares occurring, in any such case,
prior to the Distribution Date.

                Preferred Shares purchasable upon exercise of the Rights will
not be redeemable. Each Preferred Share will be entitled to a minimum
preferential quarterly dividend payment of $1 per share but will be entitled to
an aggregate dividend of 1,000 times the dividend declared per Common Share. In
the event of liquidation, the holders of the Preferred Shares will be entitled
to a minimum preferential liquidation payment of $1,000 per share but will be
entitled to an aggregate payment of 1,000 times the payment made per

<PAGE>   87
                                                                               4

Common Share. Each Preferred Share will have 1,000 votes, voting together with
the Common Shares. Finally, in the event of any merger, consolidation or other
transaction in which Common Shares are exchanged, each Preferred Share will be
entitled to receive 1,000 times the amount received per Common Share. These
rights are protected by customary antidilution provisions.

                Because of the nature of the Preferred Shares' dividend,
liquidation and voting rights, the value of the one one-thousandth interest in a
Preferred Share purchasable upon exercise of each Right should approximate the
value of one Common Share.

                In the event that the Company is acquired in a merger or other
business combination transaction or 50% or more of its consolidated assets or
earning power are sold after a person or group has become an Acquiring Person,
proper provision will be made so that each holder of a Right will thereafter
have the right to receive, upon the exercise thereof at the then current
exercise price of the Right, that number of shares of common stock of the
acquiring company (or its parent) which at the time of such transaction will
have a market value of two times the exercise price of the Right. In the event
that any person or group of affiliated or associated persons becomes an
Acquiring Person, each holder of a Right, other than Rights beneficially owned
by the Acquiring Person (which will thereafter be void), will thereupon have the
right to receive upon exercise that number of Common Shares having a market
value of two times the exercise price of the Right.

                At any time after any person or group becomes an Acquiring
Person and prior to the acquisition by such person or group of 50% or more of
the outstanding Common Shares, the Board of Directors of the Company may
exchange the Rights (other than Rights owned by such person or group which will
have become void), in whole or in part, for shares of Common Shares or Preferred
Shares (or a series of the Company's preferred stock having equivalent rights,
preferences and privileges), at an exchange ratio of one share of Class A Common
Stock or one share of Class B Common Stock, or a fractional Preferred Share (or
other preferred stock) equivalent in value thereto, per Class A Right or Class B
Right, as the case may be.

                With certain exceptions, no adjustment in the

<PAGE>   88
                                                                               5

Purchase Price will be required until cumulative adjustments require an
adjustment of at least 1% in such Purchase Price. No fractional Preferred Shares
will be issued (other than fractions which are integral multiples of ---one
one-thousandth of a Preferred Share, which may, at the election of the Company,
be evidenced by depositary receipts) and, in lieu thereof, an adjustment in cash
will be made based on the market price of the Preferred Shares on the last
trading day prior to the date of exercise.

                At any time prior to the time an Acquiring Person becomes such,
the Board of Directors of the Company may redeem the Rights in whole, but not in
part, at a price of $.01 per Right (the "Redemption Price") payable, at the
option of the Company, in cash, Common Shares or such other form of
consideration as the Board of Directors of the Company shall determine. The
redemption of the Rights may be made effective at such time on such basis with
such conditions as the Board of Directors in its sole discretion may establish.
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

                At any time prior to such time as there shall be an Acquiring
Person, the Company may, without the approval of any holder of the Rights,
supplement or amend any provision of the Rights Agreement (including the date on
which the Expiration Date or the Distribution Date shall occur, the amount of
the Purchase Price or the definition of "Acquiring Person"), except that no
supplement or amendment shall be made that reduces the Redemption Price of the
Rights. From and after such time as any person or group of affiliated or
associated persons becomes an Acquiring Person, and subject to applicable law,
the Company may, and the Rights Agent shall if the Company so directs, amend
this Rights Agreement without the approval of any holders of Rights (a) to cure
any ambiguity or to correct or supplement any provision contained herein which
may be defective or inconsistent with any other provision of this Rights
Agreement or (b) to otherwise change or supplement any other provisions in this
Agreement in any matter which the Company may deem necessary or desirable and
which in each such case shall not (i) adversely affect the interests of the
holders of Rights as such (other than an Acquiring Person or an Affiliate or
Associate of an Acquiring Person), (ii) cause the Rights Agreement again to
become otherwise amendable or

                                                                               6

(iii) cause the Rights again to become redeemable.

                Until a Right is exercised or exchanged, the holder thereof, as
such, will have no rights as a stockholder of the Company, including, without
limitation, the right to vote or to receive dividends.

                A copy of the Rights Agreement has been filed with the
Securities and Exchange Commission as an Exhibit to a Registration Statement on
Form S-1 (Registration No. 333-51594). A copy of the Rights Agreement is
available free of charge from the Company. This summary description of the
Rights does not purport to be complete and is qualified in its entirety by
reference to the Rights Agreement, as the same may be amended from time to time,
which is hereby incorporated herein by reference.
