                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

         infoUSA, Inc. (the "Company") hereby amends and restates in its
entirety the Registration Statement on Form 8-A relating to the Company's Common
Stock, filed by the Company on October 19, 1991, and amended on October 6, 1997.

ITEM 1.       DESCRIPTION OF SECURITIES TO BE REGISTERED

         This Registration Statement relates to the Common Stock of the Company.

         Prior to October 21, 1999, the Company had two classes of Common Stock,
designated "Class A Common Stock" and "Class B Common Stock." On October 21,
1999, the stockholders of the Company approved an amendment to the Company's
Certificate of Incorporation to (i) authorize a new class of common stock,
designated as Common Stock (the "Reclassified Common Stock"), (ii) combine and
reclassify the Company's Class A Common Stock and Class B Common Stock into the
Reclassified Common Stock on a one-for-one basis, and (iii) establish the
rights, powers and limitations of the Reclassified Common Stock. An amendment to
the Company's Certificate of Incorporation, setting forth the rights, powers,
and limitations of the Reclassified Common Stock, was filed with the Secretary
of State of the State of Delaware on October 22, 1999. Following such amendment,
the Company's authorized capital stock consists of 295,000,000 shares of Common
Stock, par value $0.0025, and 5,000,000 shares of Preferred Stock, par value
$0.0025. Of the Preferred Stock, 255,000 shares have been designated Series A
Preferred Stock and 4,745,000 remain undesignated.

         The following summary of certain features of the Common Stock and
Preferred Stock does not purport to be complete and is subject to, and qualified
in its entirety by, the provisions of the Company's Certificate of
Incorporation, as amended, and Certificate of Designation, as amended, which are
included as exhibits to this Registration Statement, and by the provisions of
applicable law.

COMMON STOCK

         The holders of Common Stock may take action by written consent in
accordance with Delaware law, but do not have the right to cumulate votes in
connection with the election of Directors. In the event of a liquidation,
dissolution or winding up of the Company and subject to any rights of the
Preferred Stock, the holders of each class of Common Stock shall first receive
any declared but unpaid dividends with respect to such class, and then shall be
entitled to share ratably in all assets remaining after payment of the Company's
liabilities. A sale of all or substantially all of the Company's assets or a
merger in which the stockholders of the Company immediately prior to the merger
own less than a majority of the voting power of the surviving entity following
the merger, will be treated as a liquidation, dissolution or winding up of the
Company. The Common Stock has no preemptive, conversion or other subscription
rights and there are no redemption or sinking fund provisions applicable to the
Common Stock. All outstanding shares of Common Stock are fully paid and
non-assessable. There are no restrictions on the transferability of the Common
Stock, except for such restrictions as may be entered into by the holders
thereof contractually, or may be imposed on the holders thereof by applicable
laws.



                                       2
<PAGE>   3
         Voting Rights. Holders of the Common Stock are entitled to one vote
per share on all matters submitted to a vote of the stockholders.

         Dividend Rights. The Class B Common Stock does not have any right to
receive dividends unless and until such dividends are declared by the Board of
Directors out of funds legally available therefor. All such dividends declared
on Common Stock shall be paid at an equal per-share rate. The Company has not
paid any cash dividends since its inception, and does not anticipate paying cash
dividends in the foreseeable future. The Company currently intends to retain
available future earnings to finance the operations of the business.

PREFERRED STOCK

         Series A Preferred Stock

         No shares of Series A Preferred Stock are currently outstanding. The
Series A Preferred Stock was designated by the Board of Directors in connection
with the Company's stockholder rights plans. The Series A Preferred Stock is
issuable upon the exercise of certain currently unexercisable purchase rights,
which rights are currently attached to and trade with the outstanding shares of
Common Stock. Because of the voting, dividend and liquidation rights of each
series of Preferred Stock, described below, the value of a one-thousandth
interest in one share of Series A Preferred Stock should approximate the value
of one share of Common Stock. The Preferred Stock purchase rights, and the
conditions upon which they detach from the Common Stock and become exercisable,
are discussed in detail at "Certain Anti-Takeover Effects--Stockholder Rights
Plan."

         Upon issuance of Preferred Stock, the holders thereof, together with
the holders of Common Stock, may take action by written consent in accordance
with Delaware law, but will not have the right to cumulate votes in connection
with the election of Directors. The Preferred Stock has no preemptive,
conversion or other subscription rights and there are no redemption or sinking
fund provisions applicable to the Preferred Stock. There are no restrictions on
the transferability of the Preferred Stock, except for such restrictions as may
be entered into by the holders thereof contractually, or may be imposed on the
holders thereof by applicable laws.

         Voting Rights. Holders of the Series A Preferred Stock are entitled
to 1,000 votes per share on all matters submitted to a vote of the stockholders.
The votes of holders of Series A Preferred Stock will be counted together with
the votes of the Common Stock for all purposes, unless the matter to be voted on
would increase or decrease the par value of such series or alter or change the
powers, preferences or special rights of the shares of such series so as to
affect it adversely.

         Dividend Rights. The Series A Preferred Stock is entitled to a
dividend equal to 1,000 times any dividend declared per share of Common Stock.

         Liquidation Rights. In the event of a liquidation, dissolution or
winding up of the Company holders of Series A Preferred Stock are entitled to
receive 1,000 times any amount payable to the Common Stock, plus, any accrued
but unpaid dividends. As is the case for the Common Stock, a sale of all or
substantially all of the Company's assets or a merger in which the stockholders
of the Company, immediately prior to the merger own less than a majority of the
voting power of the



                                       3
<PAGE>   4

surviving entity following the merger, will be treated as a liquidation,
dissolution or winding up of the Company.

      Undesignated Preferred Stock

         Pursuant to the Company's Certificate of Incorporation, the Board of
Directors has the authority, without further action by the stockholders, to
issue the remaining 4,745,000 undesignated shares of Preferred Stock in one or
more series and to fix the designations, powers, preferences and privileges, and
relative participating, optional or special rights and the qualifications,
limitations or restrictions thereof, including dividend rights, conversion
rights, voting rights, terms of redemption and liquidation preferences, any or
all of which may be greater than the rights of the Common Stock or the Series A
Preferred Stock. The Board of Directors, without stockholder approval, can issue
Preferred Stock with voting, conversion or other rights that could adversely
affect the voting power and other rights of holders of Common Stock or the
Series A Preferred Stock. Preferred Stock could thus be issued quickly with
terms calculated to delay, or prevent a change in control of the Company or make
removal of management more difficult. Additionally, the issuance of Preferred
Stock may have the effect of decreasing the market price of the Common Stock,
and may adversely affect the voting and the other rights of the holders of
Common Stock. At present, there are no shares of Preferred Stock outstanding and
the Company has no plans to issue any of the Preferred Stock, except as
described above. See "Series A Preferred Stock."

TRANSFER AGENT AND REGISTRAR

         The Transfer Agent and Registrar for the Company's Common Stock is
Norwest Shareowner Services of Minnesota.

CERTAIN ANTI-TAKEOVER EFFECTS

         Stockholder Rights Plan. The Board has adopted a stockholder rights
plan with respect to its Common Stock (the "Rights Plan"). Pursuant to the
Rights Plan, the Board declared a dividend distribution of Series A Preferred
Stock purchase rights to the holders of Common Stock (the "Rights"). The Rights
currently trade with shares of the Company's Common Stock and have no impact on
the way the Company's shares are traded. The Rights are not exercisable until
ten days after a person or group (other than present holders of more than 15% of
the Company's voting stock, including the Company's Chairman, Vinod Gupta, or
members of his family) announces acquisition of 15% or more of the Company's
outstanding voting stock or the commencement of a tender offer which would
result in ownership by the person or group of 15% or more of the outstanding
voting stock.

         Once a person or group (the "Acquiring Person") acquires 15% or more of
the Company's voting stock (a "Trigger Event"), each Right not owned by the
Acquiring Person will entitle its holder to purchase, at such Right's then
current exercise price, that number of shares of Common Stock of the Company
(or, in certain circumstances as determined by the Board, cash, other property
or other securities) having a market value at that time of twice such Right's
exercise price. If, after the tenth day following acquisition by such Acquiring
Person of 15% or more of the Company's voting stock, the Company sells more than
50% of its assets or earning power or is acquired in a merger or other


                                       4
<PAGE>   5

business combination transaction, the Acquiring Person must assume the
obligations under the Rights and the Rights will become exercisable to acquire
common stock of the Acquiring Person at the discounted price. The Rights are
redeemable at the Company's option for $0.001 per Right at any time on or prior
to public announcement that a Person has acquired beneficial ownership of 15% or
more of the Company's voting stock.

         The Rights are designed to protect and maximize the value of
stockholders' interests in the Company in the event of an unsolicited takeover
attempt through such methods as a gradual accumulation of shares in excess of
15% of the outstanding stock followed by a two-tier tender offer or other
tactics that do not treat all shareholders equally. The Rights Plan is not
intended to prevent a takeover, but instead to protect stockholders from the
abusive and coercive tactics that often occur in takeover attempts. These
tactics may unfairly pressure stockholders, deprive them of the full value of
their shares, or squeeze them out of their investment without giving them any
real choice.

         Classified Board of Directors. The Company's Certificate of
Incorporation currently provides for three classes of directors, each with
three-year terms. The term of one class of Directors terminates at each annual
meeting of stockholders. As a result, stockholders desiring to replace the
incumbent directors and gain control of the Board would be required to win at
least two annual contests before their nominees constituted a majority of
directors.

         Super-majority Required to Amend Certificate of Incorporation. The
Company's Certificate of Incorporation provides that the affirmative vote of the
holders of at least 60% of the shares entitled to vote, voting together as a
single class, is required to amend provisions of the Certificate of
Incorporation. These provisions of the Certificate of Incorporation could
discourage potential acquisition proposals and could delay or prevent a change
in control of the Company.

         Section 203 of the Delaware General Corporation Law. Finally, because
the Company has not by a provision in its Certificate of Incorporation elected
otherwise, it is subject to Section 203 of the Delaware General Corporation Law
("Section 203"), which imposes certain restrictions, described below,
on"business combinations" with an "interested stockholder" that could produce
anti-takeover effects in certain circumstances. Section 203 defines a business
combination to include: (i) any merger or consolidation involving the
corporation and the interested stockholder; (ii) any sale, transfer, pledge or
other disposition involving the interested stockholder of 10% or more of the
assets of the corporation; (iii) subject to certain exceptions, any transaction
which results in the issuance or transfer by the corporation of any stock of the
corporation to the interested stockholder; (iv) any transaction involving the
corporation which has the effect of increasing the proportionate share of the
stock of any class or series of the corporation beneficially owned by the
interested stockholder; or (v) the receipt by the interested stockholder of the
benefit of any loans, advances, guarantees, pledges or other financial benefits
provided by or through the corporation. In general, Section 203 defines an
"interested stockholder" as any entity or person beneficially owning 15% or more
of the outstanding voting stock of the corporation and any entity or person
affiliated with or controlling or controlled by such entity or person.

         Subject to certain exceptions, Section 203 prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder for a period of three years following the time that such stockholder
became an interested stockholder, unless (i) prior to such time, the board



                                       5
<PAGE>   6

of directors of the corporation approved either the business combination or the
transaction which resulted in the stockholder becoming an interested
stockholder, (ii) upon consummation of the transaction which resulted in the
stockholder becoming an interested stockholder, the interested stockholder owned
at least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced (not counting those shares owned by directors who are also
officers and by employee stock plans in which employee participants do not have
the right to determine confidentially whether shares held subject to the plan
will be tendered in a tender or exchange offer), or (iii) at or subsequent to
such time, the business combination is approved by the board of directors and
authorized at an annual or special meeting of stockholders, and not by written
consent, by the affirmative vote of at least 66 2/3% of the outstanding voting
stock which is not owned by the interested stockholder.

                                   ARTICLE I.
                                      Name

     The name of the Corporation shall be infoUSA Inc.

Company.


                                  ARTICLE III.
                                     Purpose

     The purpose of the Corporation is to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of
Delaware.


                                   ARTICLE IV.
                                Authorized Stock

     The total number of shares of all classes of capital stock which the
corporation shall have authority to issue is three hundred million (300,000,000)
shares which shall be divided into two classes as follows:

          (i) Two Hundred Ninety_Five Million (295,000,000) shares of Common
     Stock with a par value of one fourth of one cent ($0.0025) per share; and

          (ii) Five Million (5,000,000) shares of Preferred Stock with a par
     value of one fourth of one cent ($0.0025) per share.

     Upon this Certificate of Amendment of Certificate of Incorporation becoming
effective pursuant to the General Corporation Law of the State of Delaware (the
"Effective Time"), and without any further action on the part of the Corporation
or its stockholders, each share of the Corporation's Class A Common Stock and
Class B Common Stock, one fourth of one cent ($.0025) par value, then issued
(including shares held in the treasury of the Corporation), shall be
automatically reclassified, changed and converted into one (1) fully paid and
non_assessable share of Common Stock, one fourth of one cent ($.0025) par value.
Any stock certificate which, immediately prior to the Effective Time, represents
shares of Class A Common Stock or Class B Common Stock, one fourth of one cent
($0.0025) par value, will, from and after the Effective Time, automatically and
without the necessity of presenting the same for exchange, represent that number
of shares of Common Stock equal to the number of shares of Class A Common Stock
or Class B Common Stock represented by such certificate prior to the Effective
Time. As soon as practicable after the Effective Time, the Corporation's
transfer




                                       1

agent shall mail a transmittal letter to each record holder who then
holds shares of Class A or Class B Common Stock, informing such persons of this
reclassification with appropriate instructions on exchanging certificates
representing such shares and other relevant matters.

     Each holder of shares of Common Stock of the Company shall be entitled to
one vote for each share of Common Stock held in the name of such holder on the
books of the Company. The holder of each share of a series of Preferred Stock
shall be entitled to such voting rights as may be authorized by the Board of
Directors pursuant to Article V of this Certificate.


                                   ARTICLE V.
                        Rights and Preferences of Holders
                               of Preferred Stock

     The Board of Directors is authorized, subject to limitations prescribed by
law and the provisions of Article IV, to provide for the issuance of the shares
of Preferred Stock in series, and by filing a Certificate pursuant to the
applicable law of the State of Delaware, to establish from time to time the
number of shares to be included in each such series, and to fix the designation,
powers, preferences and rights of the shares of each such series and the
qualifications, limitations or restrictions thereof.

     The authority of the Board of Directors with respect to each series of
Preferred Stock shall include, but not be limited to, determination of the
following:

A.   The number of shares constituting that series and the distinctive
     designation of that series;

B.   The dividend rate on the shares of that series, whether dividends shall be
     cumulative, and if so, from which data or dates, and the relative rights of
     priority, if any, of payment of dividends on shares of that series;

C.   Whether that series shall have voting rights, in addition to the voting
     rights provided by law, and if so, the terms of such voting rights;

D.   Whether that series shall have conversion privileges, and if so, the terms
     and conditions of such conversion privileges, including provision for
     adjustment of the conversion rate in such events as the Board of Directors
     shall determine;

E.   Whether or not the shares of that series shall be redeemable, and, if so,
     the terms and conditions of such redemption, including the date or date
     upon or after which they shall be redeemable, and the amount per share
     payable in case of redemption, which amount may vary under different
     conditions and at different redemption dates;

     declared and set apart for payment before any dividend shall be paid or
     declared and set apart for payment on the Common Stock with respect to the
     same dividend period.

     If upon any voluntary or involuntary liquidation, dissolution or winding up
of the Corporation, the assets available for distribution to holders of shares

                                   ARTICLE VI.
                                  Incorporator

     The name and mailing address of the Incorporator is Vinod Gupta, 5711 South
86th Circle, Omaha, Nebraska 68127. Until the directors are elected, the
Incorporator shall manage the affairs of the Corporation, including the adoption
of the original bylaws of the Corporation and may do whatever is necessary and
proper to effect the organization of the Corporation and the election of
directors.


                                  ARTICLE VII.
                                Preemptive Rights

     The holders of Common Stock or Preferred Stock of the Corporation shall
have no preemptive rights to subscribe for any shares of any class of stock of
the Corporation whether now or hereafter authorized.


                                  ARTICLE VIII.
                               Board of Directors

A.   The number of Directors constitution the entire Board shall be not less
     than three (3) nor more than fifteen (15), as fixed from time to time by
     vote of the majority of the entire Board; provided, however, that the
     number of Directors shall not be reduced so as to shorten the term of any
     Director at the time in office.

B.   The Board of Directors shall be divided into three classes, as nearly equal
     in numbers as the then total number of Directors constituting the entire
     Board permits with the term of office of one class expiring each year. At
     the first annual meeting of shareholders in 1992, the term of office of the
     first class of Directors will expire and at which them their successors
     shall be elected for a term expiring at the third succeeding annual meeting
     after their election. At the annual meeting of the shareholders in 1993,
     the term of office of the second class of Directors will expire and at
     which time their successors shall be elected for a term expiring at the
     third succeeding annual meeting after their election. At the annual meeting
     of the shareholders in 1994, the term of office of the third class of
     Directors will expire and at which time their successors shall be elected
     for a term expiring at the third succeeding annual meeting after their
     election. Any vacancies in the Board of Directors for any reason, and any
     directorships resulting from any increase in the number of Directors, may
     be filled by the Board of Directors, acting by a majority of the Directors
     then in office, although less than a quorum, and any Director so chosen
     shall hold office until the next election of the class for which such
     Director shall have been chosen. Subject to the foregoing, at each annual
     meeting of shareholders, the successors to the class of Directors whose
     term shall then expire shall be elected to hold office for a term expiring
     at the third succeeding annual meeting after their election.

C.   Notwithstanding any other provisions of this Certificate of Incorporation
     or the Bylaws of the Corporation (and notwithstanding the fact that some
     lesser percentage may be specified by law, this Certificate of
     Incorporation or the Bylaws of the Corporation), any director or the entire
     Board of Directors of the Corporation may be removed at any time, but only
     for cause and only by affirmative vote of the holders of fifty percent
     (50%) or more of the outstanding shares of capital stock of the Corporation
     entitled to vote generally in the election of Directors (considered for
     this purpose as one class) cast at a meeting of the shareholders called for
     that purpose.


                                   ARTICLE IX.
                                     Bylaws

     All of the powers of the Corporation, insofar as the same may be lawfully
vested by this Certificate of Incorporation in the Board of Directors, are
hereby conferred upon the Board of Directors of the Corporation. Except as
otherwise provided in this Article IX, and in furtherance, and not in limitation
of that power, the Board of Directors shall have the power to make, adopt,
alter, amend and repeal from time to time the Bylaws of the corporation, subject
to the right of the shareholders entitled to vote with respect thereto to adopt,
alter, amend and repeal Bylaws made by the Board of Directors. The shareholders
may expressly provide in any bylaw that such bylaw may not be altered, amended
or repealed by the Board of Directors; and a bylaw so providing may not be
altered, amended or repealed by the Board of Directors.


                                   ARTICLE X.
                              Amendment of Articles

     Notwithstanding any other provision of this Certificate of Incorporation or
the Bylaws of the Corporation (in addition to any other vote that may be
required by law, this Certificate of Incorporation or the Bylaws), the
affirmative vote of the holders of at least sixty percent (60%) of the
outstanding shares of the Common Stock of the Corporation, and any series of
Preferred Stock entitled to vote generally in the election of Directors
(considered for this purpose as one class) shall be required to amend, alter or
repeal any provision of this Certificate of Incorporation.


                                   ARTICLE XI.
                             Liability of Directors

     No Director of the Corporation shall be personally liable to the
Corporation or its shareholders for monetary damages for breach of fiduciary
duty as a Director; provided, however, that the foregoing clause shall not apply
to any liability of a Director: (i) for any breach of the Director's duty of
loyalty to the Corporation or its shareholders; (ii) for acts or omissions not
in good faith or which involved intentional misconduct or a knowing violation of
law; (iii) under Section 174 of the General Corporation Law of the State of
Delaware; or (iv) for any transaction from which the Director derived an
improper personal benefit. If the General Corporation Law of the State of
Delaware is amended to authorize corporate action further eliminating or
limiting the personal liability of the Directors, then the liability of the
Director of the Corporation shall be eliminated or limited to the fullest extent
permitted by the General Corporation Law of the State of Delaware, as so
amended. Any repeal or modification of this Article XI shall not adversely
effect any right or protection of a Director of




                                       4

the Corporation existing hereunder with respect to any act or omission occurring
prior to such repeal or modification.


                                  ARTICLE XII.
                                 Director Voting

     Unless otherwise provided by resolution by the Board of Directors, it shall
not be required that elections of Directors be conducted by written ballot.


                                  ARTICLE XIII.
                                 Indemnification

     The Corporation shall to the extent required, and may, to the extent
permitted, by Section 145 of the Delaware General Corporation Law, as amended
from time to time, indemnify and reimburse all persons whom it may indemnify and
reimburse pursuant thereto. Notwithstanding the foregoing, the indemnification
provided for in this Article XIII shall not be deemed exclusive of any other
rights to which those entitled to receive indemnification or reimbursement
hereunder may be entitled under any bylaw of this Corporation, agreement, vote
or consent of shareholders or disinterested directors or otherwise.

                                  INFOUSA INC.

               (FORMERLY THE AMENDED CERTIFICATE OF DESIGNATION OF
       RIGHTS, PREFERENCES AND PRIVILEGES OF PARTICIPATING PREFERRED STOCK
          OF AMERICAN BUSINESS INFORMATION, INC. DATED OCTOBER 3, 1997)


         The undersigned, Stormy Dean and Fred Vakili, do hereby certify:

         1. That they are the duly elected and acting Vice President and
Secretary, respectively, of infoUSA Inc., a Delaware corporation (the
"Corporation").

         2. That pursuant to the authority conferred upon the Board of Directors
by the Certificate of Incorporation of the said Corporation, the said Board of
Directors on October 18, 1999 adopted the following resolution amending and
restating the Amended Certificate of Designation of Rights, Preferences and
Privileges of Participating Preferred Stock of American Business Information,
Inc. dated October 3, 1997, reclassifying and combining the previously
authorized Series A Participating Preferred Stock, with 220,000 shares
authorized, and the previously authorized Series B Preferred Stock, with 35,000
shares authorized, into a single series of Participating Preferred Stock,
designated "Series A Participating Preferred Stock":

         "RESOLVED, that pursuant to the authority vested in the Board of
Directors of the Corporation by the Restated Certificate of Incorporation, as
amended, the Board of Directors does hereby provide for the issue of a series of
Preferred Stock of the Corporation and does hereby fix and herein state and
express the designations, powers, preferences and relative and other special
rights and the qualifications, limitations and restrictions of such series of
Preferred Stock as follows:

         Section 1. Designation and Amount.

                  (a) The shares of such series shall be designated as "SERIES A
PARTICIPATING PREFERRED STOCK." The Series A Participating Preferred Stock shall
have a par value of $0.0025 per share, and the number of shares constituting
such series shall be 255,000.

                  (b) Upon this Amended Certificate of Designation becoming
effective pursuant to the General Corporation Law of the State of Delaware (the
"EFFECTIVE TIME"), and without any further action on the part of the Corporation
or its stockholders, each share of the Corporation's Series A Participating
Preferred Stock, one fourth of one cent ($0.0025) par value, then authorized,
and each share of the Corporation's Series B Participating Preferred Stock, one
fourth of one cent

                                       1

<PAGE>   2

($0.0025) par value, then authorized, shall be automatically reclassified,
changed and converted into one (1) share of Series A Participating Preferred
Stock, one fourth of one cent ($0.0025) par value.

         Section 2. Proportional Adjustment. In the event the Corporation shall
at any time after the issuance of any share or shares of Series A Participating
Preferred Stock (i) declare any dividend on Common Stock of the Corporation
("COMMON STOCK") payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the Corporation shall
simultaneously effect a proportional adjustment to the number of outstanding
shares of Series A Participating Preferred Stock.

         Section 3. Dividends and Distributions.

                  (a) Subject to the prior and superior right of the holders of
any shares of any series of Preferred Stock ranking prior and superior to the
shares of Series A Participating Preferred Stock with respect to dividends, the
holders of shares of Series A Participating Preferred 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 last day
of January, April, July and October 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 Participating Preferred Stock, in an amount per share
(rounded to the nearest cent) equal to 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 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 Participating Preferred
Stock.

                  (b) The Corporation shall declare a dividend or distribution
on the Series A Participating Preferred Stock as provided in paragraph (a) above
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock).

                  (c) Dividends shall begin to accrue on outstanding shares of
Series A Participating Preferred Stock from the Quarterly Dividend Payment Date
next preceding the date of issue of such shares of Series A Participating
Preferred Stock, 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
Participating 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 from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the
shares of Series A Participating 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

                                       2

<PAGE>   3

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 Participating Preferred Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be no more
than 30 days prior to the date fixed for the payment thereof.

         Section 4. Voting Rights. The holders of shares of Series A
Participating Preferred Stock shall have the following voting rights:

                  (a) Each share of Series A Participating Preferred Stock shall
entitle the holder thereof to 1,000 votes on all matters submitted to a vote of
the stockholders of the Corporation.

                  (b) Except as otherwise provided herein or by law, the holders
of shares of Series A Participating Preferred Stock and the holders of shares of
Common Stock shall vote together as one class on all matters submitted to a vote
of stockholders of the Corporation.

                  (c) Except as required by law, holders of Series A
Participating 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.

         Section 5. Certain Restrictions.

                  (a) The Corporation shall not declare any dividend on, make
any distribution on, or redeem or purchase or otherwise acquire for
consideration any shares of Common Stock after the first issuance of a share or
fraction of a share of Series A Participating Preferred Stock unless
concurrently therewith it shall declare a dividend on the Series A Participating
Preferred Stock as required by Section 3 hereof.

                  (b) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Participating Preferred Stock as provided
in Section 3 are in arrears, thereafter and until all accrued and unpaid
dividends and distributions, whether or not declared, on shares of Series A
Participating Preferred Stock outstanding shall have been paid in full, the
Corporation shall not

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

                           (ii)     declare or pay dividends on, 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 Series A
Participating Preferred Stock, except dividends paid ratably on the Series A
Participating 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;

                                       3

<PAGE>   4

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

                           (iv)     purchase or otherwise acquire for
consideration any shares of Series A Participating Preferred Stock, or any
shares of stock ranking on a parity with the Series A Participating 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.

                  (c) 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 5, purchase or otherwise acquire such shares at such time and in
such manner.

         Section 6. Reacquired Shares. Any shares of Series A Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their cancellation become authorized but unissued
shares of Preferred Stock and may be reissued as part of a new series of
Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein and, in the Restated Certificate of Incorporation, as then amended.

         Section 7. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, the holders of shares
of Series A Participating Preferred Stock shall be entitled to receive an
aggregate amount per share equal to 1000 times the aggregate amount to be
distributed per share to holders of shares of Common Stock plus an amount equal
to any accrued and unpaid dividends on such shares of Series A Participating
Preferred Stock.

         Section 8. Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the 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 the shares of
Series A Participating Preferred Stock shall at the same time be similarly
exchanged or changed in an amount per share 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.

         Section 9. No Redemption. The shares of Series A Participating
Preferred Stock shall not be redeemable.

                                       4

<PAGE>   5

         Section 10. Ranking. The Series A Participating Preferred Stock shall
rank junior to all other series of the Corporation's Preferred Stock as to the
payment of dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise.

         Section 11. Amendment. The Restated Certificate of Incorporation of the
Corporation shall not be further amended in any manner which would materially
alter or change the powers, preference or special rights of the Series A
Participating Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of a majority of the outstanding shares of
Series A Participating Preferred Stock, voting separately as a class.

         Section 12. Fractional Shares. Series A Participating Preferred Stock
may be issued in fractions of a share which shall entitle the holder, in
proportion to such holder's fractional shares, to exercise voting rights,
receive dividends, participate in distributions and to have the benefit of all
other rights of holders of Series A Participating Preferred Stock.

         RESOLVED FURTHER, that the Chief Executive Officer, the Chief Financial
Officer or any Vice President and the Secretary or any Assistant Secretary of
this corporation be, and they hereby are, authorized and directed to prepare and
file an Amended Certificate of Designation of Rights, Preferences and Privileges
in accordance with the foregoing resolution and the provisions of Delaware law
and to take such actions as they may deem necessary or appropriate to carry out
the intent of the foregoing resolution."

         We further declare under penalty of perjury that the matters set forth
in the foregoing Certificate of Designation are true and correct of our own
knowledge.

                        PREFERRED SHARES RIGHTS AGREEMENT
          (FORMERLY THE "AMENDED AND RESTATED SERIES B PREFERRED SHARES
                    RIGHTS AGREEMENT" DATED OCTOBER 3, 1997)

         This Amended and Restated Agreement ("Agreement") is dated as of

         On July 21, 1997 (the "Rights Dividend Declaration Date"), the Board of
Directors of the Company authorized and declared a dividend of one Preferred
Share Purchase Right (a "Right") for each share of common stock of the Company
outstanding as of the Close of Business (as hereinafter defined) on August 14,
1997 (the "Record Date"), each Right representing the right to purchase one
one-thousandth of a share of Series A Participating Preferred Stock pursuant to
the Preferred Shares Rights Agreement, dated July 21, 1997, and further
authorized and directed the issuance of one Right (as such number may be
adjusted pursuant to the provisions of this Agreement) with respect to each
share of common stock 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), and in certain circumstances after the Distribution Date.

         On October 3, 1997, the Company (i) reclassified its existing common
stock as Class B Common Stock (the "First Reclassification"), (ii) filed an
Amended Certificate of Designation of Rights, Preferences, and Privileges of
Participating Preferred Stock, which reclassified the Series A Preferred Stock
authorized theretofore as Series B Preferred Stock and authorized a new Series A
Preferred Stock, (iii) approved an Amended and Restated Series B Preferred
Shares Rights Agreement to, among other things, grant holders of Class B Common
Stock rights to purchase for each share of Class B Common Stock held by them
1/1000 share of Series B Preferred Stock instead of, and not in addition to, the
1/1000 of a share of Series A Preferred Stock, and to make certain other changes
to account for the First Reclassification.

         On October 3, 1997, the Board of Directors of the Company also
authorized and declared a dividend of one Series A Preferred Share Purchase
Right for each share of Class A Common Stock of the Company to be paid in the
form of a dividend on each share of Class B Common Stock outstanding as of
October 3, 1997, each Right representing the right to purchase one
one-thousandth of a share of Series A Participating Preferred Stock pursuant to
the provisions of the Series A Preferred Shares Rights Agreement, dated October
3, 1997, and further authorized and directed the issuance of one Right with
respect to each share of Class A Common Stock 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), and in certain
circumstances after the Distribution Date.

         On October 21, 1999, the Company (i) authorized a new class of common
stock, designated as Common Stock (the "Reclassified Common Stock"), (ii)
combined and reclassified the Company's Class A Common Stock and Class B Common
Stock into the Reclassified Common Stock on a one-for-one basis (the "Second
Reclassification"), (iii) filed an Amended Certificate of Designation of Rights,
Preferences, and Privileges of Participating Preferred Stock, in the form
attached hereto as Exhibit A, which combined and reclassified the Company's
Series A Preferred Stock and Series B Preferred Stock authorized theretofore
into a single class designated Series A Preferred Stock

<PAGE>   5



("Reclassified Series A Preferred Stock") on a one-for-one basis, (iv)
established the rights, powers and limitations of the Reclassified Common Stock
and Reclassified Series A Preferred Stock, and (v) combined the Series A
Preferred Shares Rights Agreement with and into the Amended and Restated Series
B Preferred Shares Rights Agreement and in connection therewith approved this
amended and restated Agreement to, among other things, grant holders of
Reclassified Common Stock rights to purchase for each share of Reclassified
Common Stock held by them 1/1000 share of Reclassified Series A Preferred Stock
instead of, and not in addition to, the 1/1000 of a share of Series A Preferred
Stock or Series B Preferred Stock authorized heretofore, and to make certain
other changes to account for the Second Reclassification.

         The shares of Reclassified Common Stock are referred to herein as
"Common Shares" and the shares of Reclassified Series A Preferred Stock are
referred to herein as "Preferred Shares."

         NOW, THEREFORE, in consideration of the promises 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:

                  (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 15% or more of the Common Shares then outstanding, but shall
not include the Company, any Subsidiary of the Company or 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 any of the
persons or entities, singly or together, set forth on Schedule 1 to this
Agreement. Notwithstanding the foregoing, no Person shall be deemed to be 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 15% or more of the Common
Shares of the Company then outstanding; provided, however, that if a Person
shall become the Beneficial Owner of 15% or more of the Common Shares of the
Company then outstanding by reason of share purchases by the Company and shall,
after such share purchases 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 in
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 of the Company
such Person does not beneficially own 15% or more of the Common Shares of the
Company then outstanding. Notwithstanding the foregoing, (i) if the Company's
Board of Directors determines in good faith that a Person who would otherwise be
an "Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph (a), has become such inadvertently (including, without limitation,
because (A) such Person was unaware that it beneficially owned a percentage of
the Common Shares that would otherwise cause such Person to be an "Acquiring
Person," as defined pursuant to the foregoing provisions of this paragraph (a),
or (B) such Person was aware of the extent of the Common Shares it beneficially
owned but had no actual knowledge of the consequences of such beneficial
without any intention of changing or influencing control of the Company, and if
such Person divested or divests as promptly as practicable a sufficient number
of Common Shares so that such Personownership under this Agreement) and
without any intention of changing or influencing control of the Company, and if
such Person divested or divests as promptly as practicable a sufficient number
of Common Shares so that such Person

                                        2

<PAGE>   6
would no longer be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph (a), then such Person shall not be deemed to be or
to have become an "Acquiring Person" for any purposes of this Agreement; and
(ii) if, as of the date hereof, any Person is the Beneficial Owner of 15% or
more of the Common Shares outstanding, such Person shall not be or become an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph (a), unless and until such time as such Person shall become the
Beneficial Owner of additional Common Shares (other than pursuant to a dividend
or distribution paid or made by the Company on the outstanding Common Shares in
Common Shares or pursuant to a split or subdivision of the outstanding Common
Shares), unless, upon becoming the Beneficial Owner of such additional Common
Shares, such Person is not then the Beneficial Owner of 15% or more of the
Common Shares then outstanding.

                  (b)       "Adjustment Fraction" shall have the meaning set
forth in Section 11(a)(i) hereof.

                  (c)       "Affiliate" and "Associate" shall have the

Agreement.

                  (d)       A Person shall be deemed the "Beneficial Owner" of
and shall be deemed to "Beneficially Own" any securities:

                           (i)      which such Person or any of such Person's
Affiliates or Associates beneficially owns, directly or indirectly, for purposes

comparable or successor law or regulation);

                           (ii)     which such Person or any of such Person's
Affiliates or Associates has (A) the right to acquire (whether such right is
exercisable immediately or only 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 the Rights), warrants or options, or
otherwise; provided, however, that a Person shall not be deemed pursuant to this
Section 1(d)(ii)(A) to be the Beneficial Owner of, or to beneficially own, (1)
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

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 of the Exchange Act and (2) is not also then reportable on Schedule
13D under the Exchange Act (or any comparable or successor report); or

indirectly, by any other Person (or any Affiliate or Associate thereof) with
which such Person or any of such Person's Affiliates or Associates has any
agreement, arrangement or understanding, whether or not in writing (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)(ii)(B)) or disposing of any securities of the Company; provided,
however, that in no case shall an officer or director of the Company be deemed
(x) the Beneficial Owner of any securities beneficially owned by another officer
or director of the Company solely by reason of actions undertaken by such
persons in their capacity as officers or directors of the Company or (y) the
Beneficial Owner of securities held of record by the trustee of any employee
benefit plan of the Company or any Subsidiary of the Company for the benefit of
any employee of the Company or any Subsidiary of the Company, other than the

those made pursuant to Section 11(a)(iii) hereof, shall mean the average of the
daily closing prices per share of such Security for the thirty (30) consecutive
Trading Days immediately prior to such date, and for purposes of computations

combination or reclassification of such Security, and prior to the expiration of
the applicable thirty (30) Trading Day or ten (10) Trading Day period, 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

by the Board of Directors of the Company shall be used. 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 this Section 1(j), as appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof, multiplied by 1000. If the Security is not

                  (b) On the Record Date or as soon as practicable thereafter,
the Company will send a copy of the Summary of Rights by first-class,
postage-prepaid mail, to each record holder of Common Shares as of the Close of
Business on the Record Date, at the address of such holder shown on the records
of the Company's transfer agent and registrar. With respect to certificates for
Common Shares outstanding as of the Record Date, until the Distribution Date,
the Rights will be evidenced by such certificates registered in the names of the
holders thereof together with the Summary of Rights. Until the Distribution Date
(or, if earlier, the Expiration Date), the surrender for transfer of any
certificate for Common Shares outstanding on the Record Date, with or without a
copy of the Summary of Rights, shall also constitute the transfer of the Rights
associated with the Common Shares represented thereby.

                  (c) Unless the Board of Directors by resolution adopted at or
before the time of the issuance of any Common Shares specifies to the contrary,
Rights shall be issued in respect of all Common Shares that are issued after the
Record Date but prior to the earlier of the Distribution Date or the Expiration
Date or, in certain circumstances provided in Section 22 hereof, after the
Distribution Date. Certificates representing such Common Shares shall also be
deemed to be certificates for Rights, and shall bear the following legend:

         THIS CERTIFICATE ALSO EVIDENCES AND ENTITLES THE HOLDER HEREOF TO
         CERTAIN RIGHTS AS SET FORTH IN A RIGHTS AGREEMENT BETWEEN INFOUSA INC.
         AND NORWEST BANK MINNESOTA, N.A., AS THE RIGHTS AGENT, DATED AS OF
         OCTOBER 3, 1997 (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 INFOUSA INC. UNDER CERTAIN
         CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT, SUCH
         RIGHTS WILL BE EVIDENCED BY SEPARATE CERTIFICATES AND WILL NO LONGER BE
         EVIDENCED BY THIS CERTIFICATE. INFOUSA INC. WILL MAIL TO THE HOLDER OF
         THIS CERTIFICATE A COPY OF THE RIGHTS AGREEMENT WITHOUT CHARGE AFTER
         RECEIPT OF A WRITTEN



                                       8

         REQUEST THEREFOR. UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE RIGHTS
         AGREEMENT, RIGHTS ISSUED TO, OR HELD BY, ANY PERSON WHO IS, WAS OR
         BECOMES AN ACQUIRING PERSON OR ANY AFFILIATE OR ASSOCIATE THEREOF (AS
         SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT), WHETHER CURRENTLY
         HELD BY OR ON BEHALF OF SUCH PERSON OR BY ANY SUBSEQUENT HOLDER, MAY
         BECOME NULL AND VOID.

With respect to such certificates containing the foregoing legend, until the
earlier of (i) the Distribution Date or (ii) the Expiration 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 shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby.

                  (d) In the event that the Company purchases or 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 exercise any Rights associated with
the Common Shares which are no longer outstanding.

         SECTION 4. FORM OF RIGHTS CERTIFICATES.

                  (a) The Rights Certificates (and the forms of election to
purchase Common Shares and of assignment to be printed on the reverse thereof)
shall be substantially in the form of Exhibit B 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 a national market system, on which
the Rights may from time to time be listed or included, or to conform to usage.
Subject to the provisions of Section 11 and Section 22 hereof, the Rights
Certificates, whenever distributed, shall be dated as of the Record Date (or in
the case of Rights issued with respect to Common Shares issued by the Company
after the Record Date, as of the date of issuance of such Common Shares) and on
their face shall entitle the holders thereof to purchase such number of
one-thousandths of a Preferred Share as shall be set forth therein at the price
set forth therein (such exercise price per one one-thousandth of a Preferred
Share being hereinafter referred to as the "Exercise Price" and the aggregate
Exercise Price of all Preferred Shares issuable upon exercise of one Right being
hereinafter referred to as the "Total Exercise Price"), but the number and type
of securities purchasable upon the exercise of each Right and the Exercise Price
shall be subject to adjustment as provided herein.

                  (b) Any Rights Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights beneficially owned by: (i) an Acquiring
Person or any Associate or Affiliate of an Acquiring Person, (ii) a transferee
of an Acquiring Person (or of any such Associate or Affiliate)
who becomes a transferee after the Acquiring Person becomes such or (iii) a
transferee of an Acquiring Person (or of any such Associate or Affiliate) who
becomes a transferee prior to or concurrently with the Acquiring Person becoming
such and receives such Rights pursuant to either (A) a transfer (whether or not
for consideration) from the Acquiring Person to holders of equity



                                       9
<PAGE>   13

interests in such Acquiring Person or to any Person with whom such Acquiring
Person has any continuing agreement, arrangement or understanding regarding the
transferred Rights or (B) a transfer which the Company's Board of Directors has
determined is part of a plan, arrangement or understanding which has as a
primary purpose or effect avoidance of Section 7(e) hereof, and any Rights
Certificate issued pursuant to Section 6 or Section 11 hereof upon transfer,
exchange, replacement or adjustment of any other Rights Certificate referred to
in this sentence, shall contain (to the extent feasible) the following legend:

         THE RIGHTS REPRESENTED BY THIS RIGHTS CERTIFICATE ARE OR WERE
         BENEFICIALLY OWNED BY A PERSON WHO WAS OR BECAME AN ACQUIRING PERSON OR
         AN AFFILIATE OR ASSOCIATE OF AN ACQUIRING PERSON (AS SUCH TERMS ARE
         DEFINED IN THE RIGHTS AGREEMENT). ACCORDINGLY, THIS RIGHTS CERTIFICATE
         AND THE RIGHTS REPRESENTED HEREBY MAY BECOME NULL AND VOID IN THE
         CIRCUMSTANCES SPECIFIED IN SECTION 7(e) OF THE RIGHTS AGREEMENT.

         SECTION 5. COUNTERSIGNATURE AND REGISTRATION.

                  (a) The Rights Certificates shall be executed on behalf of the
Company by its Chairman of the Board, its Chief Executive Officer, its Chief
Financial Officer, its President or any Vice President, either manually or by
facsimile signature, and by the Secretary or an Assistant Secretary of the
Company, either manually or by facsimile signature, and shall have affixed
thereto the Company's seal (if any) or a facsimile thereof. The Rights
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 Rights Certificates shall cease to be
such officer of the Company before countersignature by the Rights Agent and
issuance and delivery by the Company, such Rights 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 person who signed such Rights
Certificates on behalf of the Company had not ceased to be such officer of the
Company; and any Rights Certificate may be signed on behalf of the Company by
any person who, at the actual date of the execution of such Rights Certificate,
shall be a proper officer of the Company to sign such Rights Certificate,
although at the date of the execution of this Rights Agreement any such person
was not such an officer.

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

         SECTION 6. TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF RIGHTS
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHTS CERTIFICATES.

                  (a) Subject to the provisions of Sections 7(e) and 14 hereof,
at any time after the Close of Business on the Distribution Date, and at or
prior to the Close of Business on the Expiration



                                       10
<PAGE>   14

Date, any Rights Certificate or Rights Certificates may be transferred, split
up, combined or exchanged for another Rights Certificate or Rights Certificates,
entitling the registered holder to purchase a like number of one-thousandths of
a Preferred Share (or, following a Triggering Event, other securities, cash or
other assets, as the case may be) as the Rights Certificate or Rights
Certificates surrendered then entitled such holder to purchase. Any registered
holder desiring to transfer, split up, combine or exchange any Rights
Certificate or Rights Certificates shall make such request in writing delivered
to the Rights Agent, and shall surrender the Rights Certificate or Rights
Certificates to be transferred, split up, combined or exchanged at the office of
the Rights Agent designated for such purpose. Neither the Rights Agent nor the
Company shall be obligated to take any action whatsoever with respect to the
transfer of any such surrendered Rights Certificate until the registered holder
shall have completed and signed the certificate contained in the form of
assignment on the reverse side of such Rights Certificate and shall have
provided such additional evidence of the identity of the Beneficial Owner (or
former Beneficial Owner) or Affiliates or Associates thereof as the Company
shall reasonably request. Thereupon the Rights Agent shall, subject to Sections
7(e) and 14 hereof, countersign and deliver to the person entitled thereto a
Rights Certificate or Rights 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 Rights Certificates.

                  (b) Upon receipt by the Company and the Rights Agent of
evidence reasonably satisfactory to them of the loss, theft, destruction or
mutilation of a Rights 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
cancellation of the Rights Certificate if mutilated, the Company will make and
deliver a new Rights Certificate of like tenor to the Rights Agent for delivery
to the registered holder in lieu of the Rights Certificate so lost, stolen,
destroyed or mutilated.

         SECTION 7. EXERCISE OF RIGHTS; EXERCISE PRICE; EXPIRATION DATE OF
RIGHTS.

                  (a) Subject to Sections 7(e) and 23(b) hereof, the registered
holder of any Rights Certificate may exercise the Rights evidenced thereby
(except as otherwise provided herein) in whole or in part at any time after the
Distribution Date and prior to the Close of Business on the Expiration Date by
surrender of the Rights Certificate, with the form of election to purchase on
the reverse side thereof duly executed, to the Rights Agent at the office of the
Rights Agent designated for such purpose, together with payment of the Exercise
Price for each one-thousandth of a Preferred Share (or, following a Triggering
Event, other securities, cash or other assets as the case may be) as to which
the Rights are exercised.

                  (b) The Exercise Price for each one-thousandth of a Preferred
Share issuable pursuant to the exercise of a Right shall initially be Sixty
Dollars ($60.00), shall be subject to adjustment from time to time as provided
in Sections 11 and 13 hereof and shall be payable in lawful money of the United
States of America in accordance with paragraph (c) below.

                  (c) Upon receipt of a Rights Certificate representing
exercisable Rights, with the form of election to purchase duly executed,
accompanied by payment of the Exercise Price for the




                                       11
<PAGE>   15

number of one-thousandths of a Preferred Share (or, following a Triggering
Event, other securities, cash or other assets as the case may be) to be
purchased and an amount equal to any applicable transfer tax required to be paid
by the holder of such Rights Certificate in accordance with Section 9(e) hereof,
the Rights Agent shall, subject to Section 20(k) hereof, 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) a
certificate or certificates for the number of one-thousandths of a Preferred
Share (or, following a Triggering Event, other securities, cash or other assets
as the case may be) to be purchased and the Company hereby irrevocably
authorizes its transfer agent to comply with all such requests or (B) if the
Company shall have elected to deposit the total number of one-thousandths of a
Preferred Share (or, following a Triggering Event, other securities, cash or
other assets as the case may be) issuable upon exercise of the Rights hereunder
with a depositary agent, requisition from the depositary agent depositary
receipts representing such number of one-thousandths of a Preferred Share (or,
following a Triggering Event, other securities, cash or other assets as the case
may be) as are to be purchased (in which case certificates for the Preferred
Shares (or, following a Triggering Event, other securities, cash or other assets
as the case may be) represented by such receipts shall be deposited by the
transfer agent with the depositary agent) and the Company hereby directs the
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) 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 Rights Certificate, registered in
such name or names as may be designated by such holder and (iv) when
appropriate, after receipt thereof, deliver such cash to or upon the order of
the registered holder of such Rights Certificate. The payment of the Exercise
Price (as such amount may be reduced (including to zero) pursuant to Section
11(a)(iii) hereof) and an amount equal to any applicable transfer tax required
to be paid by the holder of such Rights Certificate in accordance with Section
9(e) hereof, may be made in cash or by certified bank check, cashier's check or
bank draft payable to the order of the Company. In the event that the Company is
obligated to issue securities of the Company other than Preferred Shares, pay
cash and/or distribute other property pursuant to Section 11(a) hereof, the
Company will make all arrangements necessary so that such other securities, cash
and/or other property are available for distribution by the Rights Agent, if and
when appropriate.

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

                  (e) Notwithstanding anything in this Agreement to the
contrary, from and after the first occurrence of a Triggering Event, any Rights
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an
Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee after the Acquiring Person
becomes such (a "POST-EVENT TRANSFEREE"), (iii) a transferee of an Acquiring
Person (or of any such Associate or Affiliate) who becomes a transferee prior to
or concurrently with the Acquiring Person becoming such and receives such Rights
pursuant to either (A) a transfer (whether or not for consideration) from the
Acquiring Person to holders of equity interests in such Acquiring Person or to
any Person with whom the Acquiring Person has any continuing agreement,
arrangement or understanding regarding the transferred Rights or (B) a transfer
which the Company's Board of Directors has



                                       12
<PAGE>   16

determined is part of a plan, arrangement or understanding which has as a
primary purpose or effect the avoidance of this Section 7(e) (a "PRE-EVENT
TRANSFEREE") or (iv) any subsequent transferee receiving transferred Rights from
a Post-Event Transferee or a Pre-Event Transferee, either directly or through
one or more intermediate transferees, shall become null and void without any
further action and no holder of such Rights shall have any rights whatsoever
with respect to such Rights, whether under any provision of this Agreement or
otherwise. The Company shall use all reasonable efforts to ensure that the
provisions of this Section 7(e) and Section 4(b) hereof are complied with, but
shall have no liability to any holder of Rights Certificates or to any other
Person as a result of its failure to make any determinations with respect to an
Acquiring Person or any of such Acquiring Person's Affiliates, Associates or
transferees hereunder.

                  (f) 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 upon the occurrence of
any purported exercise as set forth in this Section 7 unless such registered
holder shall, in addition to having complied with the requirements of Section
7(a), have (i) completed and signed the certificate contained in the form of
election to purchase set forth on the reverse side of the Rights Certificate
surrendered for such exercise and (ii) provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request.

         SECTION 8. CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES. All
Rights 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 cancellation or in canceled form,
or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights
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 cancellation and retirement, and the Rights Agent shall so cancel and
retire, any Rights Certificate purchased or acquired by the Company otherwise
than upon the exercise thereof. The Rights Agent shall deliver all canceled
Rights Certificates to the Company.

         SECTION 9. RESERVATION AND AVAILABILITY OF PREFERRED SHARES.

                  (a) The Company covenants and agrees that it will use its best
efforts to cause to be reserved and kept available out of its authorized and
unissued Preferred Shares not reserved for another purpose (and, following the
occurrence of a Triggering Event, out of its authorized and unissued Common
Shares and/or other securities), the number of Preferred Shares (and, following
the occurrence of the Triggering Event, Common Shares and/or other securities)
that will be sufficient to permit the exercise in full of all outstanding
Rights.

                  (b) If the Company shall hereafter list any of its Preferred
Shares on a national securities exchange, then so long as the Preferred Shares
(and, following the occurrence of a Triggering Event, Common Shares and/or other
securities) issuable and deliverable upon exercise of the Rights may be listed
on such exchange, the Company shall use its best efforts to cause, from and
after such time as the Rights become exercisable (but only to the extent that it
is reasonably likely that the Rights will be exercised), all shares reserved for
such issuance to be listed on such exchange upon official notice of issuance
upon such exercise.



                                       13
<PAGE>   17

                  (c) The Company shall use its best efforts to (i) file, as
soon as practicable following the earliest date after the first occurrence of a
Triggering Event in which the consideration to be delivered by the Company upon
exercise of the Rights is described in Section 11(a)(ii) or Section 11(a)(iii)
hereof, or as soon as is required by law following the Distribution Date, as the
case may be, a registration statement under the Securities Act with respect to
the securities purchasable upon exercise of the Rights on an appropriate form,
(ii) cause such registration statement to become effective as soon as
practicable after such filing and (iii) cause such registration statement to
remain effective (with a prospectus at all times meeting the requirements of the
Securities Act) until the earlier of (A) the date as of which the Rights are no
longer exercisable for such securities and (B) the date of expiration of the
Rights. The Company may temporarily suspend, for a period not to exceed ninety
(90) days after the date set forth in clause (i) of the first sentence of this
Section 9(c), the exercisability of the Rights in order to prepare and file such
registration statement and permit it to become effective. Upon any such
suspension, the Company shall issue a public announcement stating, and notify
the Rights Agent, that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement and notification to the Rights Agent
at such time as the suspension is no longer in effect. The Company will also
take such action as may be appropriate under, or to ensure compliance with, the
securities or "blue sky" laws of the various states in connection with the
exercisability of the Rights. 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, or an
exemption therefrom shall be available, and until a registration statement has
been declared effective.

                  (d) The Company covenants and agrees that it will take all
such action as may be necessary to ensure that all Preferred Shares (or other
securities of the Company) delivered upon exercise of Rights shall, at the time
of delivery of the certificates for such securities (subject to payment of the
Exercise Price), be duly and validly authorized and issued and fully paid and
nonassessable shares.

                  (e) 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 original issuance or delivery of the
Rights Certificates or of any Preferred Shares (or other securities of the
Company) 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 Rights Certificates to a person other than, or the issuance or
delivery of certificates or depositary receipts for the Preferred Shares (or
other securities of the Company) in a name other than that of, the registered
holder of the Rights Certificate evidencing Rights surrendered for exercise or
to issue or to deliver any certificates or depositary receipts for Preferred
Shares (or other securities of the Company) upon the exercise of any Rights
until any such tax shall have been paid (any such tax being payable by the
holder of such Rights Certificate at the time of surrender) or until it has been
established to the Company's satisfaction that no such tax is due.

         SECTION 10. RECORD DATE. Each Person in whose name any certificate for
a number of one-thousandths of a Preferred Share (or other securities of the
Company) is issued upon the exercise of Rights shall for all purposes be deemed
to have become the holder of record of Preferred Shares (or other securities of
the Company) represented thereby on, and such certificate shall be dated, the



                                       14
<PAGE>   18

date upon which the Rights Certificate evidencing such Rights was duly
surrendered and payment of the Total Exercise Price with respect to which the
Rights have been exercised (and any applicable transfer taxes) was made;
provided, however, that if the date of such surrender and payment is a date upon
which the 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 transfer books of the
Company are open. Prior to the exercise of the Rights evidenced thereby, the
holder of a Rights Certificate shall not be entitled to any rights of a holder
of Preferred Shares (or other securities of the Company) 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 EXERCISE PRICE, NUMBER OF SHARES OR NUMBER OF
RIGHTS. The Exercise Price, the number and kind of shares or other property
covered by each Right and the number of Rights outstanding are subject to
adjustment from time to time as provided in this Section 11.

                  (a) (i) Anything in this Agreement to the contrary
notwithstanding, in the event the Company shall at any time after the date of
this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares (by reverse stock split or otherwise) 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), then, in each such event,
except as otherwise provided in this Section 11 and Section 7(e) hereof: (1) the
Exercise Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price thereafter shall equal the result obtained
by dividing the Exercise Price in effect immediately prior to such time by a
fraction (the "ADJUSTMENT FRACTION"), the numerator of which shall be the total
number of Preferred Shares (or shares of capital stock issued in such
reclassification of the Preferred Shares) outstanding immediately following such
time and the denominator of which shall be the total number of Preferred Shares
outstanding immediately prior to such time; 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 such Right; and (2) the number of one-thousandths of a
Preferred Share (or share of such other capital stock) issuable upon the
exercise of each Right shall equal the number of one-thousandths of a Preferred
Share (or share of such other capital stock) as was issuable upon exercise of a
Right immediately prior to the occurrence of the event described in clauses (A)
- - (D) of this Section 11(a)(i), multiplied by the Adjustment Fraction; provided,
however, that, no such adjustment shall be made pursuant to this Section
11(a)(i) to the extent that there shall have simultaneously occurred an event
described in clause (A), (B), (C) or (D) of Section 11(n) with a proportionate
adjustment being made thereunder. Each Common Share that shall become
outstanding after an adjustment has been made pursuant to this Section 11(a)(i)
shall have associated with it the number of Rights, exercisable at the Exercise
Price and for the number of one-thousandths of a Preferred Share (or shares of
such other capital stock) as one Common Share has associated with it immediately
following the adjustment made pursuant to this Section 11(a)(i).


                                       15
<PAGE>   19
                           (ii)     In the event a Triggering Event shall have
occurred, then promptly following such Triggering Event each holder of a Right,
except as provided in Section 7(e) hereof, shall thereafter have the right to
receive for each Right, upon exercise thereof in accordance with the terms of
this Agreement and payment of the Exercise Price in effect immediately prior to
the occurrence of the Triggering Event, in lieu of a number of one-thousandths
of a Preferred Share, such number of Common Shares of the Company as shall equal
the result obtained by multiplying the Exercise Price in effect immediately
prior to the occurrence of the Triggering Event by the number of one-thousandths
of a Preferred Share for which a Right was exercisable (or would have been
exercisable if the Distribution Date had occurred) immediately prior to the
first occurrence of a Triggering Event, and dividing that product by 50% of the
Current Per Share Market Price for Common Shares on the date of occurrence of
the Triggering Event; provided, however, that the Exercise Price and the number
of Common Shares of the Company so receivable upon exercise of a Right shall be
subject to further adjustment as appropriate in accordance with Section 11(e)
hereof to reflect any events occurring in respect of the Common Shares of the
Company after the occurrence of the Triggering Event.

                           (iii)    In lieu of issuing Common Shares in
accordance with Section 11(a)(ii) hereof, the Company may, if the Company's
Board of Directors determines that such action is necessary or appropriate and
not contrary to the interest of holders of Rights and, in the event that the
number of Common Shares which are authorized by the Company's Certificate of
Incorporation but not outstanding or reserved for issuance for purposes other
than upon exercise of the Rights are not sufficient to permit the exercise in
full of the Rights, or if any necessary regulatory approval for such issuance
has not been obtained by the Company, the Company shall: (A) determine the
excess of (1) the value of the Common Shares issuable upon the exercise of a
Right (the "CURRENT VALUE") over (2) the Exercise Price (such excess, the
"SPREAD") and (B) with respect to each Right, make adequate provision to
substitute for such Common Shares, upon exercise of the Rights, (1) cash, (2) a
reduction in the Exercise Price, (3) other equity securities of the Company
(including, without limitation, shares or units of shares of any series of
preferred stock which the Company's Board of Directors has deemed to have the
same value as Common Shares (such shares or units of shares of preferred stock
are herein called "COMMON STOCK EQUIVALENTS")), except to the extent that the
Company has not obtained any necessary stockholder or regulatory approval for
such issuance, (4) debt securities of the Company, except to the extent that the
Company has not obtained any necessary stockholder or regulatory approval for
such issuance, (5) other assets or (6) any combination of the foregoing, having
an aggregate value equal to the Current Value, where such aggregate value has
been determined by the Company's Board of Directors based upon the advice of a
nationally recognized investment banking firm selected by the Company's Board of
Directors; provided, however, if the Company shall not have made adequate
provision to deliver value pursuant to clause (B) above within thirty (30) days
following the later of (x) the first occurrence of a Triggering Event and (y)
the date on which the Company's right of redemption pursuant to Section 23(a)
expires (the later of (x) and (y) being referred to herein as the "Section
11(a)(ii) Trigger Date"), then the Company shall be obligated to deliver, upon
the surrender for exercise of a Right and without requiring payment of the
Exercise Price, Common Shares (to the extent available), except to the extent
that the Company has not obtained any necessary stockholder or regulatory
approval for such issuance, and then, if necessary, cash, which shares and/or
cash have an aggregate value equal to the Spread. If the Company's Board of
Directors shall determine in good faith that it is likely that sufficient
additional Common Shares could be authorized for issuance upon exercise in full
of the

                                       16

Rights or that any necessary regulatory approval for such issuance will be
obtained, 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 stockholder approval for the
authorization of such additional shares or take action to obtain such regulatory
approval (such period, as it may be extended, the "Substitution Period"). To the
extent that the Company determines that some action need be taken pursuant to
the first and/or second sentences of this Section 11(a)(iii), the Company (x)
shall provide, subject to Section 7(e) 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, to take any action to obtain any required
regulatory approval and/or to decide the appropriate form of distribution to be
made pursuant to such first 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 the Common Shares
shall be the Current Per Share Market Price of the Common Shares on the Section
11(a)(ii) Trigger Date and the value of any Common Stock Equivalent shall be
deemed to have the same value as the Common Shares on such date.

                  (b) In case the Company shall, at any time after the date of
this Agreement, fix a record date for the issuance of rights, options or
warrants to all holders of Preferred Shares entitling such holders (for a period
expiring within forty-five (45) calendar days after such record date) to
subscribe for or purchase Preferred Shares or Equivalent Shares or securities
convertible into Preferred Shares or Equivalent Shares at a price per share (or
having a conversion price per share, if a security convertible into Preferred
Shares or Equivalent Shares) less than the then Current Per Share Market Price
of the Preferred Shares or Equivalent Shares on such record date, then, in each
such case, the Exercise Price to be in effect after such record date shall be
determined by multiplying the Exercise Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the number of
Preferred Shares and Equivalent Shares (if any) outstanding on such record date,
plus the number of Preferred Shares or Equivalent Shares, as the case may be,
which the aggregate offering price of the total number of Preferred Shares or
Equivalent Shares, as the case may be, to be offered or issued (and/or the
aggregate initial conversion price of the convertible securities to be offered
or issued) would purchase at such current market price, and the denominator of
which shall be the number of Preferred Shares and Equivalent Shares (if any)
outstanding on such record date, plus the number of additional Preferred Shares
or Equivalent Shares, as the case may be, 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 Company's
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. Preferred Shares and Equivalent 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 Exercise Price shall be adjusted to be the Exercise Price
which would then be in effect if such record date had not been fixed.

                                       17

<PAGE>   21

                  (c) In case the Company shall, at any time after the date of
this Agreement, fix a record date for the making of a distribution to all
holders of the Preferred Shares or of any class or series of Equivalent 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, if any, or a dividend payable in Preferred Shares) or subscription
rights, options or warrants (excluding those referred to in Section 11(b)),
then, in each such case, the Exercise Price to be in effect after such record
date shall be determined by multiplying the Exercise Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
Current Per Share Market Price of a Preferred Share or an Equivalent Share on
such record date, less the fair market value per Preferred Share or Equivalent
Share (as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent) of the portion of the cash, assets or evidences of indebtedness so to be
distributed or of such subscription rights or warrants applicable to a Preferred
Share or Equivalent Share, as the case may be, and the denominator of which
shall be such Current Per Share Market Price of a Preferred Share or Equivalent
Share on such record date; 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. 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 Exercise Price shall be adjusted to be the Exercise Price which would have
been in effect if such record date had not been fixed.

                  (d) Anything herein to the contrary notwithstanding, no
adjustment in the Exercise Price shall be required unless such adjustment would
require an increase or decrease of at least 1% in the Exercise Price; provided,
however, that any adjustments which by reason of this Section 11(d) 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 nearest cent or to the nearest ten-thousandth of a Common Share or other
share or one hundred-thousandth of a Preferred Share, as the case may be.
Notwithstanding the first sentence of this Section 11(d), any adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
(3) years from the date of the transaction which requires such adjustment or
(ii) the Expiration Date.

                  (e) If as a result of an adjustment made pursuant to Section
11(a) or 13(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive any shares of capital stock other than Preferred Shares,
thereafter the number of such other shares so receivable upon exercise of any
Right and, if required, the Exercise Price thereof, 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
Sections 11(a),11(b), 11(c), 11(d), 11(g), 11(h), 11(i), 11(j), 11(k) and 11(l),
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.

                  (f) All Rights originally issued by the Company subsequent to
any adjustment made to the Exercise Price hereunder shall evidence the right to
purchase, at the adjusted Exercise Price, the number of 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.



                                       18
<PAGE>   22

                  (g) Unless the Company shall have exercised its election as
provided in Section 11(h), upon each adjustment of the Exercise Price as a
result of the calculations made in Section 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 Exercise Price, that number of Preferred
Shares (calculated to the nearest one hundred-thousandth of a share) obtained by
(i) multiplying (x) the number of Preferred Shares covered by a Right
immediately prior to this adjustment, by (y) the Exercise Price in effect
immediately prior to such adjustment of the Exercise Price, and (ii) dividing
the product so obtained by the Exercise Price in effect immediately after such
adjustment of the Exercise Price.

                  (h) The Company may elect on or after the date of any
adjustment of the Exercise Price as a result of the calculations made in Section
11(b) or (c) to adjust the number of Rights, in substitution for any adjustment
in the number of Preferred Shares 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-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 hundred-thousandth) obtained by
dividing the Exercise Price in effect immediately prior to adjustment of the
Exercise Price by the Exercise Price in effect immediately after adjustment of
the Exercise 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 Exercise Price is adjusted or any day
thereafter, but, if the Rights Certificates have been issued, shall be at least
ten (10) days later than the date of the public announcement. If Rights
Certificates have been issued, upon each adjustment of the number of Rights
pursuant to this Section 11(h), the Company shall, as promptly as practicable,
cause to be distributed to holders of record of Rights Certificates on such
record date Rights 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 Rights
Certificates held by such holders prior to the date of adjustment, and upon
surrender thereof, if required by the Company, new Rights Certificates
evidencing all the Rights to which such holders shall be entitled after such
adjustment. Rights Certificates so to be distributed shall be issued, executed
and countersigned in the manner provided for herein (and may bear, at the option
of the Company, the adjusted Exercise Price) and shall be registered in the
names of the holders of record of Rights Certificates on the record date
specified in the public announcement.

                  (i) Irrespective of any adjustment or change in the Exercise
Price or the number of Preferred Shares issuable upon the exercise of the
Rights, the Rights Certificates theretofore and thereafter issued may continue
to express the Exercise Price per one one-thousandth of a Preferred Share and
the number of one-thousandths of a Preferred Share which were expressed in the
initial Rights Certificates issued hereunder.

                  (j) Before taking any action that would cause an adjustment
reducing the Exercise Price below the par or stated value, if any, of the number
of one-thousandths of a Preferred Share 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 as
fully



                                       19
<PAGE>   23

paid and nonassessable shares such number of one-thousandths of a Preferred
Share at such adjusted Exercise Price.

                  (k) In any case in which this Section 11 shall require that an
adjustment in the Exercise 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 number of one-thousandths of a Preferred Share and other capital stock or
securities of the Company, if any, issuable upon such exercise over and above
the number of one-thousandths of a Preferred Share and other capital stock or
securities of the Company, if any, issuable upon such exercise on the basis of
the Exercise 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
(fractional or otherwise) upon the occurrence of the event requiring such
adjustment.

                  (l) Anything in this Section 11 to the contrary
notwithstanding, prior to the Distribution Date, the Company shall be entitled
to make such reductions in the Exercise 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 (i) consolidation
or subdivision of the Preferred or Common Shares, (ii) issuance wholly for cash
of any Preferred or Common Shares at less than the current market price, (iii)
issuance wholly for cash of Preferred or Common Shares or securities which by
their terms are convertible into or exchangeable for Preferred or Common Shares,
(iv) stock dividends or (v) issuance of rights, options or warrants referred to
in this Section 11, hereafter made by the Company to holders of its Preferred or
Common Shares shall not be taxable to such stockholders.

                  (m) The Company covenants and agrees that, after the
Distribution Date, it will not, except as permitted by Sections 23 or 27 hereof,
take (or permit to be taken) any action if at the time such action is taken it
is reasonably foreseeable that such action will diminish substantially or
otherwise eliminate the benefits intended to be afforded by the Rights.

                  (n) In the event the Company shall at any time after the date
of this Agreement (A) declare a dividend on the Common Shares payable in Common
Shares, (B) subdivide the outstanding Common Shares, (C) combine the outstanding
Common Shares (by reverse stock split or otherwise) into a smaller number of
Common Shares, or (D) issue any shares of its capital stock in a
reclassification of the Common Shares (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
or surviving corporation), then, in each such event, except as otherwise
provided in this Section 11(a) and Section 7(e) hereof: (1) each Common Share
(or shares of capital stock issued in such reclassification of the Common
Shares) outstanding immediately following such time shall have associated with
it the number of Rights as were associated with one Common Share immediately
prior to the occurrence of the event described in clauses (A) - (D) above; (2)
the Exercise Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification shall be adjusted so that the Exercise Price thereafter shall
equal the result obtained by multiplying the Exercise Price in effect
immediately prior to such time by a fraction, the numerator of which shall be
the total number of Common Shares outstanding immediately prior to the event
described in clauses (A) - (D) above, and the denominator of which shall be the
total number of Common Shares outstanding

                                       20

<PAGE>   24



immediately after such event; 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 such Right; and (3) the number of one-thousandths of a Preferred
Share (or shares of such other capital stock) issuable upon the exercise of each
Right outstanding after such event shall equal the number of one-thousandths of
a Preferred Share (or shares of such other capital stock) as were issuable with
respect to one Right immediately prior to such event. Each Common Share that
shall become outstanding after an adjustment has been made pursuant to this
Section 11(n) shall have associated with it the number of Rights, exercisable at
the Exercise Price and for the number of one-thousandths of a Preferred Share
(or shares of such other capital stock) as one Common Share has associated with
it immediately following the adjustment made pursuant to this Section 11(n). If
an event occurs which would require an adjustment under both this Section 11(n)
and Section 11(a)(ii) hereof, the adjustment provided for in this Section 11(n)
shall be in addition to, and shall be made prior to, any adjustment required
pursuant to Section 11(a)(ii) hereof.

         SECTION 12. CERTIFICATE OF ADJUSTED EXERCISE PRICE OR NUMBER OF SHARES.
Whenever an adjustment is made as provided in Sections 11 and 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 Preferred Shares a copy of
such certificate and (c) mail a brief summary thereof to each holder of a Rights
Certificate in accordance with Section 25 hereof. Notwithstanding the foregoing
sentence, the failure of the Company to make such certification or give such
notice shall not affect the validity of such adjustment or the force or effect
of the requirement for such adjustment. The Rights Agent shall be fully
protected in relying on any such certificate and on any adjustment contained
therein and shall not be deemed to have knowledge of such adjustment unless and
until it shall have received such certificate.

         SECTION 13. CONSOLIDATION, MERGER OR SALE OR TRANSFER OF ASSETS OR
EARNING POWER.

                  (a)      In the event that, following a Triggering Event,
directly or indirectly:

                           (i)       the Company shall consolidate with, or
merge with and into, any other Person (other than a wholly-owned Subsidiary of
the Company in a transaction the principal purpose of which is to change the
state of incorporation of the Company and which complies with Section 11(m)
hereof);

                           (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 consolidation or merger and, in
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

                           (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 or Persons (other than the Company or one or more of
its wholly owned Subsidiaries in one or more transactions, each of which
individually (and together) complies with Section 11(m) hereof), then,
concurrent with and in each such case,



                                       21
<PAGE>   25
                                    (A)     each holder of a Right (except as
provided in Section 7(e) hereof) shall thereafter have the right to receive,
upon the exercise thereof at a price equal to the Total Exercise Price
applicable immediately prior to the occurrence of the Section 13 Event in
accordance with the terms of this Agreement, such number of validly authorized
and issued, fully paid, nonassessable and freely tradeable Common Shares of the
Principal Party (as hereinafter defined), free of any liens, encumbrances,
rights of first refusal or other adverse claims, as shall be equal to the result
obtained by dividing such Total Exercise Price by 50% of the Current Per Share
Market Price of the Common Shares of such Principal Party on the date of
consummation of such Section 13 Event, provided, however, that the Exercise
Price and the number of Common Shares of such Principal Party so receivable upon
exercise of a Right shall be subject to further adjustment as appropriate in
accordance with Section 11 (e) hereof;

                                    (B)     such Principal Party shall
thereafter be liable for, and shall assume, by virtue of such Section 13 Event,
all the obligations and duties of the Company pursuant to this Agreement;

                                    (C)     the term "Company" shall thereafter
be deemed to refer to such Principal Party, it being specifically intended that
the provisions of Section 11 hereof shall apply only to such Principal Party
following the first occurrence of a Section 13 Event;

                                    (D)     such Principal Party shall take
such steps (including, but not limited to, the reservation of a sufficient
number of its Common Shares) in connection with the consummation of any such
transaction as may be necessary to ensure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to its
Common Shares thereafter deliverable upon the exercise of the Rights; and

                                    (E)     upon the subsequent occurrence of
any consolidation, merger, sale or transfer of assets or other extraordinary
transaction in respect of such Principal Party, each holder of a Right shall
thereupon be entitled to receive, upon exercise of a Right and payment of the
Total Exercise 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 Principal Party receivable upon the exercise of such Right
pursuant to this Section 13(a), and such Principal Party 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.

                                    (F)     For purposes hereof, the
"earning power" of the Company and its Subsidiaries shall be determined in good
faith by the Company's Board of Directors on the basis of the operating earnings
of each business operated by the Company and its Subsidiaries during the three
fiscal years preceding the date of such determination (or, in the case of any
business not operated by the Company or any Subsidiary during three full fiscal
years preceding such date, during the period such business was operated by the
Company or any Subsidiary).

                  (b)      For purposes of this Agreement, the term
"Principal Party" shall mean:



                                       22
<PAGE>   26

                           (i)      in the case of any transaction described in
clause (i) or (ii) 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
clause (iii) 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 more than one Person that is a party to such
transaction or transactions receives the same portion of the assets or earning
power so transferred and each such portion would, were it not for the other
equal portions, constitute the greatest 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
have 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 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 Section 13 Event
unless the Principal Party shall have a sufficient number of authorized Common
Shares that have not been issued or reserved for issuance to permit the exercise
in full of the Rights in accordance with this Section 13 and unless prior
thereto the Company and such issuer shall have executed and delivered to the
Rights Agent a supplemental agreement confirming that such Principal Party
shall, upon consummation of such Section 13 Event, assume this Agreement in
accordance with Sections 13(a) and 13(b) hereof, that all rights of first
refusal or preemptive rights in respect of the issuance of Common Shares of such
Principal Party upon exercise of outstanding Rights have been waived, that there
are no rights, warrants, instruments or securities outstanding or any agreements
or arrangements which, as a result of the consummation of such transaction,
would eliminate or substantially diminish the benefits intended to be afforded
by the Rights and that such transaction shall not result in a default by such




                                       23
<PAGE>   27

Principal Party under this Agreement, and further providing that, as soon as
practicable after the date of such Section 13 Event, such Principal Party will:

                           (i)      prepare and file a registration statement
under the Securities Act 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 to list (or continue
the listing of) the Rights and the securities purchasable upon exercise of the
Rights on a national securities exchange or to meet the eligibility requirements
for quotation on Nasdaq and list (or continue the listing of) the Rights and the
securities purchasable upon exercise of the Rights on Nasdaq; and

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

         In the event that at any time after the occurrence of a Triggering
Event some or all of the Rights shall not have been exercised at the time of a
transaction described in this Section 13, the Rights which have not theretofore
been exercised shall thereafter be exercisable in the manner described in
Section 13(a) (without taking into account any prior adjustment required by
Section 11(a)(ii)).

                  (d) In case the "Principal Party" for purposes of Section
13(b) hereof has provision in any of its authorized securities or in its
certificate of incorporation or by-laws or other instrument governing its
corporate affairs, which provision would have the effect of (i) causing such
Principal Party to issue (other than to holders of Rights pursuant to Section 13
hereof), in connection with, or as a consequence of, the consummation of a
Section 13 Event, Common Shares or Equivalent Shares of such Principal Party at
less than the then Current Per Share Market Price thereof or securities
exercisable for, or convertible into, Common Shares or Equivalent Shares of such
Principal Party at less than such then Current Per Share 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 hereof, 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.

                  (e) The Company covenants and agrees that it shall not, at any
time after the Distribution Date, effect or permit to occur any Section 13
Event, if (i) at the time or immediately after such Section 13 Event there are
any rights, warrants or other instruments or securities outstanding or
agreements in effect which would substantially diminish or otherwise eliminate
the



                                       24
<PAGE>   28

benefits intended to be afforded by the Rights, (ii) prior to, simultaneously
with or immediately after such Section 13 Event, 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.

                  (f) 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 Rights Certificates which evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid to the registered holders of
the Rights Certificates 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 Right. For the purposes of this Section 14(a),
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, as determined pursuant to
the second sentence of Section 1(j) hereof.

                  (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions that are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of the Rights or to
distribute certificates which evidence fractional Preferred Shares (other than
fractions that 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 multiples of one
one-thousandth of a Preferred Share, the Company shall pay to the registered
holders of Rights 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 a Preferred Share. For purposes of this Section 14(b), the current
market value of a Preferred Share shall be one thousand times the closing price
of a Common Share (as determined pursuant to the second sentence of Section 1(j)
hereof) for the Trading Day immediately prior to the date of such exercise.

                  (c) The Company shall not be required to issue fractions of
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 Rights
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 a Common
Share. For purposes of this Section 14(c), the current market value of a Common
Share shall be the closing price of a Common Share (as determined pursuant to
the second sentence of Section 1(j) hereof) for the Trading Day immediately
prior to the date of such exercise.



                                       25
<PAGE>   29

                  (d) The holder of a Right by the acceptance of the Right
expressly waives his or her right to receive any fractional Rights or any
fractional shares (other than fractions that are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of a Right.

         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 Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Rights 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 Rights Certificate (or, prior to the
Distribution Date, of the Common Shares), may, in his or her own behalf and for
his or her 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 or her right to exercise the Rights evidenced by such Rights Certificate in
the manner provided in such Rights Certificate and in this Agreement. Without
limiting the foregoing or any remedies available to the holders of 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 RIGHTS HOLDERS. Every holder of a 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 Rights Certificates
are transferable only on the registry books of the Rights Agent if surrendered
at the principal office or offices of the Rights Agent designated for such
purposes, duly endorsed or accompanied by a proper instrument of transfer and
with the appropriate forms and certificates fully executed; and

                  (c)      subject to Sections 6(a) and 7(f) hereof, the Company
and the Rights Agent may deem and treat the person in whose name the Rights
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
Rights Certificates 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 shall be affected by any notice to the
contrary.

         SECTION 17. RIGHTS CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose to be the holder of the Preferred Shares
or any other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Rights Certificate be construed to confer upon the holder of any
Rights 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



                                       26
<PAGE>   30

to any corporate action, or to receive notice of meetings or other actions
affecting stockholders (except as otherwise provided in this Agreement), or to
receive dividends or subscription rights, or otherwise, until the Right or
Rights evidenced by such Rights Certificate shall have been exercised in
accordance with the provisions hereof.

         SECTION 18. CONCERNING THE RIGHTS AGENT.

                  (a) 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. In no event will the Rights Agent be liable for
special, indirect, incidental or consequential loss or damage of any kind
whatsoever, even if the Rights Agent has been advised of the possibility of such
loss or damage.

                  (b) 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
Rights 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 reasonably 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.

                  (a) 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 corporate trust business 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 any further act on the part of
any of the parties hereto; provided, however, 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 Rights 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
Rights Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Rights 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 Rights Certificates shall have the full force provided in the Rights
Certificates and in this Agreement.



                                       27
<PAGE>   31

                  (b) In case at any time the name of the Rights Agent shall be
changed and at such time any of the Rights Certificates shall have been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Rights Certificates so countersigned; and in
case at that time any of the Rights Certificates shall not have been
countersigned, the Rights Agent may countersign such Rights Certificates either
in its prior name or in its changed name; and in all such cases such Rights
Certificates shall have the full force provided in the Rights 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 Rights 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 written advice or 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 written advice or 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 (including, without limitation, the identity of any Acquiring Person and
the determination of Current Per Share Market Price) be proved or established by
the Company prior to taking or suffering any 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 Chief Financial Officer, the
Secretary or any Assistant 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.

                  (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
Rights 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 Rights 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 Rights Certificate;
nor shall it be responsible for any change in the exercisability of the Rights
or any adjustment in the terms of the Rights (including the manner, method or
amount thereof) provided for in Sections 3, 11, 13, or 23, 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 Rights Certificates
after receipt by the Rights Agent of a certificate furnished pursuant to Section
12 describing such change or adjustment); nor shall it by any act



                                       28
<PAGE>   32

hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any Preferred Shares to be issued pursuant to
this Agreement or any Rights 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 Chief Financial Officer, the Secretary or any
Assistant Secretary 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. Any application by the Rights Agent for written instructions from
the Company may, at the option of the Rights Agent, set forth in writing any
action proposed to be taken or omitted by the Rights Agent under this Rights
Agreement and the date on and/or after which such action shall be taken or such
omission shall be effective. The Rights Agent shall not be liable for any action
taken by, or omission of, the Rights Agent in accordance with a proposal
included in any such application on or after the date specified in such
application (which date shall not be less than five (5) Business Days after the
date any officer of the Company actually receives such application, unless any
such officer shall have consented in writing to an earlier date) unless, prior
to taking any such action (or the effective date in the case of an omission),
the Rights Agent shall have received written instructions in response to such
application specifying the action to be taken or omitted.

                  (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) No provision of this Agreement shall require the Rights
Agent to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder or in the exercise of its
rights if there shall be reasonable grounds for believing that repayment of such
funds or adequate indemnification against such risk or liability is not
reasonably assured to it.



                                       29
<PAGE>   33

                  (k) If, with respect to any Rights Certificate surrendered to
the Rights Agent for exercise or transfer, the certificate attached to the form
of assignment or form of election to purchase, as the case may be, has either
not been completed or indicates an affirmative response to clause 1 and/or 2
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 thirty (30) days' notice in writing mailed to the Company and to each
transfer agent of the Preferred Shares and the Common Shares by registered or
certified mail, and to the holders of the Rights Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
thirty (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 Preferred
Shares and the Common Shares by registered or certified mail, and to the holders
of the Rights 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 thirty (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
Rights Certificate (who shall, with such notice, submit his or her Rights
Certificate for inspection by the Company), then the registered holder of any
Rights 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 any state of the United
States, in good standing, which is authorized under such laws to exercise
corporate trust or stockholder services 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 $100
million. After appointment, the successor Rights Agent shall be vested with the
same powers, rights, duties and responsibilities as if 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 Preferred
Shares and the Common Shares, and mail a notice thereof in writing to the
registered holders of the Rights 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 RIGHTS CERTIFICATES. Notwithstanding any
of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Rights Certificates evidencing Rights in
such form as may be approved by its Board of Directors to reflect any adjustment
or change in the Exercise Price and the number or kind or class of shares or
other securities or property purchasable under the Rights 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 redemption or expiration of the Rights, the Company (a) shall, with
respect to Common Shares so issued or sold pursuant to the exercise of stock
options



                                       30
<PAGE>   34

or under any employee plan or arrangement or upon the exercise, conversion or
exchange of other securities of the Company outstanding at the date hereof or
upon the exercise, conversion or exchange of securities hereinafter issued by
the Company and (b) may, in any other case, if deemed necessary or appropriate
by the Board of Directors of the Company, issue Rights Certificates representing
the appropriate number of Rights in connection with such issuance or sale;
provided, however, that (i) no such Rights Certificate shall be issued and this
sentence shall be null and void ab initio if, and to the extent that, such
issuance or this sentence would create a significant risk of or result in
material adverse tax consequences to the Company or the Person to whom such
Rights Certificate would be issued or would create a significant risk of or
result in such options' or employee plans' or arrangements' failing to qualify
for otherwise available special tax treatment and (ii) no such Rights
Certificate shall be issued if, and to the extent that, appropriate adjustment
shall otherwise have been made in lieu of the issuance thereof.

         SECTION 23. REDEMPTION.

                  (a) The Company may, at its option and with the approval of
the Board of Directors, at any time prior to the Close of Business on the
earlier of (i) the Shares Acquisition Date and (ii) the Final Expiration Date,
redeem all but not less than all the then outstanding Rights at a redemption
price of $0.001 per Right, appropriately adjusted to reflect any stock split,
stock dividend or similar transaction occurring after the date hereof (such
redemption price being herein referred to as the "Redemption Price") and the
Company may, at its option, pay the Redemption Price either in Common Shares
(based on the Current Per Share Market Price thereof at the time of redemption)
or cash. Such redemption of the Rights by the Company 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 date on which the Board of Directors
elects to make the redemption effective shall be referred to as the "Redemption
Date."

                  (b) Immediately upon the action of the Board of Directors of
the Company ordering the redemption of the Rights, evidence of which shall have
been filed with the Rights Agent, 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 ten (10) days after the action of
the Board of Directors ordering the redemption of the Rights, the Company shall
give notice of such redemption to the Rights Agent and the holders of the then
outstanding Rights by mailing such notice to all such holders 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, and other than in
connection with the purchase of Common Shares prior to the Distribution Date.

         SECTION 24. NOTICE OF CERTAIN EVENTS.

                  (a) In case the Company shall propose to effect or permit to
occur any Triggering Event or Section 13 Event, the Company shall give notice
thereof to each holder of Rights in accordance with Section 25 hereof at least
twenty (20) days prior to occurrence of such Triggering Event or such Section 13
Event.

                  (b) In case any Triggering Event or Section 13 Event shall
occur, then, in any such case, the Company shall as soon as practicable
thereafter give to each holder of a Rights Certificate, in accordance with
Section 25 hereof, a notice of the occurrence of such event, which shall specify
the event and the consequences of the event to holders of Rights under Sections
11(a)(ii) and 13 hereof.

of any holders of Rights and the Rights Agent shall, if the Company so directs,
execute such supplement or amendment. From and after the occurrence of a
Distribution Date, the Company and the Rights Agent may from time to time
supplement or amend this Agreement without the approval of any holders of Rights
in order to (i) cure any ambiguity, (ii) correct or supplement any provision
contained herein which may be defective or inconsistent with any other
provisions herein, (iii) shorten or lengthen any time period hereunder or (iv)
to change or supplement the provisions hereunder in any manner that the Company
may deem necessary or desirable and that shall not adversely affect the
interests of the holders of Rights (other than an Acquiring Person or an
Affiliate or Associate of an Acquiring Person); provided, this Agreement may not
be supplemented or amended to lengthen, pursuant to clause (iii) of this
sentence, (A) a time period relating to when the Rights may be redeemed at such
time as the Rights are not then redeemable or (B) any other time period unless
such lengthening is for the purpose of protecting, enhancing or clarifying the
rights of, and/or the benefits to, the holders of Rights (other than an
Acquiring Person or an Affiliate or Associate of an Acquiring Person). Upon the
delivery of a certificate from an appropriate officer of the Company that states
that the proposed supplement or amendment is in compliance with the terms of
this Section 27, the Rights Agent shall execute such supplement or amendment.
Prior to the Distribution Date, the interests of the holders of Rights shall be
deemed coincident with the interests of the holders of Common Shares.

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 28. DETERMINATIONS AND ACTIONS BY THE BOARD OF DIRECTORS, ETC.
For all purposes of this Agreement, any calculation of the number of Common
Shares outstanding at any particular time, including for purposes of determining
the particular percentage of such outstanding Common Shares of which any Person
is the Beneficial Owner, shall be made in accordance with the last sentence of
Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act.
The Board of Directors of the Company shall have the exclusive power and
authority to administer this Agreement and to exercise all rights and powers
specifically granted to the Board, or the Company, or as may be necessary or
advisable in the administration of this Agreement, including, without
limitation, the right and power to (i) interpret the provisions of this
Agreement and (ii) make all determinations deemed necessary or advisable for the
administration of this Agreement (including a determination to redeem or not
redeem the Rights or to amend the Agreement). All such actions, calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) which are done or made by the Board
in good faith, shall (x) be final, conclusive and binding on the Company, the
Rights Agent, the holders of the Rights Certificates and all other parties and
(y) not subject the Board to any liability to the holders of the Rights.

         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 Rights 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
the Rights Certificates (and, prior to the Distribution Date, the Common
Shares).

         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;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23 hereof
shall be reinstated and shall not expire until the Close of Business on the
tenth day following the date of such determination by the Board of Directors.

         SECTION 31. GOVERNING LAW. This Agreement and each Right and each
Rights 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.

         SECTION 32. COUNTERPARTS. This Agreement may be executed in any number
of counterparts and each of such counterparts shall for all purposes be deemed
to be an original, and all such counterparts shall together constitute but one
and the same instrument.

Sections of this Agreement are inserted for convenience only and shall not
control or affect the meaning or construction of any of the provisions hereof.

                                  INFOUSA INC.

               (FORMERLY THE AMENDED CERTIFICATE OF DESIGNATION OF
       RIGHTS, PREFERENCES AND PRIVILEGES OF PARTICIPATING PREFERRED STOCK
          OF AMERICAN BUSINESS INFORMATION, INC. DATED OCTOBER 3, 1997)


         The undersigned, Stormy Dean and Fred Vakili, do hereby certify:

         1. That they are the duly elected and acting Vice President and
Secretary, respectively, of infoUSA Inc., a Delaware corporation (the
"Corporation").

         2. That pursuant to the authority conferred upon the Board of Directors
by the Certificate of Incorporation of the said Corporation, the said Board of
Directors on October 18, 1999 adopted the following resolution amending and
restating the Amended Certificate of Designation of Rights, Preferences and
Privileges of Participating Preferred Stock of American Business Information,
Inc. dated October 3, 1997, reclassifying and combining the previously
authorized Series A Participating Preferred Stock, with 220,000 shares
authorized, and the previously authorized Series B Preferred Stock, with 35,000
shares authorized, into a single series of Participating Preferred Stock,
designated "Series A Participating Preferred Stock":

         "RESOLVED, that pursuant to the authority vested in the Board of
Directors of the Corporation by the Restated Certificate of Incorporation, as
amended, the Board of Directors does hereby provide for the issue of a series of
Preferred Stock of the Corporation and does hereby fix and herein state and
express the designations, powers, preferences and relative and other special
rights and the qualifications, limitations and restrictions of such series of
Preferred Stock as follows:

         Section 1. Designation and Amount.

                  (a) The shares of such series shall be designated as "Series A
Participating Preferred Stock." The Series A Participating Preferred Stock shall
have a par value of $0.0025 per share, and the number of shares constituting
such series shall be 255,000.

                  (b) Upon this Amended Certificate of Designation becoming
effective pursuant to the General Corporation Law of the State of Delaware (the
"Effective Time"), and without any further action on the part of the Corporation
or its stockholders, each share of the Corporation's Series A Participating
Preferred Stock, one fourth of one cent ($0.0025) par value, then authorized,

                                       36

<PAGE>   40



and each share of the Corporation's Series B Participating Preferred Stock, one
fourth of one cent ($0.0025) par value, then authorized, shall be automatically
reclassified, changed and converted into one (1) share of Series A Participating
Preferred Stock, one fourth of one cent ($0.0025) par value.

         Section 2. Proportional Adjustment. In the event the Corporation shall
at any time after the issuance of any share or shares of Series A Participating
Preferred Stock (i) declare any dividend on Common Stock of the Corporation
("Common Stock") payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the Corporation shall
simultaneously effect a proportional adjustment to the number of outstanding
shares of Series A Participating Preferred Stock.

         Section 3. Dividends and Distributions.

                  (a) Subject to the prior and superior right of the holders of
any shares of any series of Preferred Stock ranking prior and superior to the
shares of Series A Participating Preferred Stock with respect to dividends, the
holders of shares of Series A Participating Preferred 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 last day
of January, April, July and October 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 Participating Preferred Stock, in an amount per share
(rounded to the nearest cent) equal to 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 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 Participating Preferred
Stock.

                  (b) The Corporation shall declare a dividend or distribution
on the Series A Participating Preferred Stock as provided in paragraph (a) above
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock).

                  (c) Dividends shall begin to accrue on outstanding shares of
Series A Participating Preferred Stock from the Quarterly Dividend Payment Date
next preceding the date of issue of such shares of Series A Participating
Preferred Stock, 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
Participating 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 from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the
shares of Series A Participating 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

                                       37

<PAGE>   41



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 Participating Preferred Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be no more
than 30 days prior to the date fixed for the payment thereof.

         Section 4. Voting Rights. The holders of shares of Series A
Participating Preferred Stock shall have the following voting rights:

                  (a) Each share of Series A Participating Preferred Stock shall
entitle the holder thereof to 1,000 votes on all matters submitted to a vote of
the stockholders of the Corporation.

                  (b) Except as otherwise provided herein or by law, the holders
of shares of Series A Participating Preferred Stock and the holders of shares of
Common Stock shall vote together as one class on all matters submitted to a vote
of stockholders of the Corporation.

                  (c) Except as required by law, holders of Series A
Participating 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.

         Section 5. Certain Restrictions.

                  (a) The Corporation shall not declare any dividend on, make
any distribution on, or redeem or purchase or otherwise acquire for
consideration any shares of Common Stock after the first issuance of a share or
fraction of a share of Series A Participating Preferred Stock unless
concurrently therewith it shall declare a dividend on the Series A Participating
Preferred Stock as required by Section 3 hereof.

                  (b) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Participating Preferred Stock as provided
in Section 3 are in arrears, thereafter and until all accrued and unpaid
dividends and distributions, whether or not declared, on shares of Series A
Participating Preferred Stock outstanding shall have been paid in full, the
Corporation shall not

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

                           (ii)     declare or pay dividends on, 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 Series A
Participating Preferred Stock, except dividends paid ratably on the Series A
Participating 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 on a parity (either as to dividends or
upon liquidation, dissolution or winding up)

                                       38

<PAGE>   42



with the Series A Participating Preferred Stock, provided that the Corporation
may at any time redeem, purchase or otherwise acquire shares of any such parity
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 Participating Preferred Stock;

                           (iv)     purchase or otherwise acquire for
consideration any shares of Series A Participating Preferred Stock, or any
shares of stock ranking on a parity with the Series A Participating 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.

                  (c) 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 5, purchase or otherwise acquire such shares at such time and in
such manner.

         Section 6.  Reacquired Shares. Any shares of Series A Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their cancellation become authorized but unissued
shares of Preferred Stock and may be reissued as part of a new series of
Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein and, in the Restated Certificate of Incorporation, as then amended.

         Section 7.  Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, the holders of shares
of Series A Participating Preferred Stock shall be entitled to receive an
aggregate amount per share equal to 1000 times the aggregate amount to be
distributed per share to holders of shares of Common Stock plus an amount equal
to any accrued and unpaid dividends on such shares of Series A Participating
Preferred Stock.

         Section 8.  Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the 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 the shares of
Series A Participating Preferred Stock shall at the same time be similarly
exchanged or changed in an amount per share 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.

         Section 9.  No Redemption. The shares of Series A Participating
Preferred Stock shall not be redeemable.

         Section 10. Ranking. The Series A Participating Preferred Stock shall
rank junior to all other series of the Corporation's Preferred Stock as to the
payment of dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise.

                                       39

<PAGE>   43



         Section 11. Amendment. The Restated Certificate of Incorporation of the
Corporation shall not be further amended in any manner which would materially
alter or change the powers, preference or special rights of the Series A
Participating Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of a majority of the outstanding shares of
Series A Participating Preferred Stock, voting separately as a class.

         Section 12. Fractional Shares. Series A Participating Preferred Stock
may be issued in fractions of a share which shall entitle the holder, in
proportion to such holder's fractional shares, to exercise voting rights,
receive dividends, participate in distributions and to have the benefit of all
other rights of holders of Series A Participating Preferred Stock.

         RESOLVED FURTHER, that the Chief Executive Officer, the Chief Financial
Officer or any Vice President and the Secretary or any Assistant Secretary of
this corporation be, and they hereby are, authorized and directed to prepare and
file an Amended Certificate of Designation of Rights, Preferences and Privileges
in accordance with the foregoing resolution and the provisions of Delaware law
and to take such actions as they may deem necessary or appropriate to carry out
the intent of the foregoing resolution."

         We further declare under penalty of perjury that the matters set forth
in the foregoing Certificate of Designation are true and correct of our own
knowledge.

                     AMENDED AND RESTATED SUMMARY OF RIGHTS

<TABLE>

<S>                               <C>
Distribution and                     The Board of Directors has declared a dividend of one Right for each
Transfer of Rights;                  share of infoUSA Common Stock outstanding. Prior to the Distribution
Rights Certificate:                  Date referred to below, the Rights will be evidenced by and trade with the
                                     certificates for the Common Stock. After the Distribution Date, infoUSA
                                     Inc. (the "COMPANY") will mail Rights certificates to the Company's
                                     stockholders and the Rights will become transferable apart from the
                                     Common Stock.

Distribution Date:                   Rights will separate from the Common Stock and become exercisable
                                     following (a) the tenth day after a person or group, other than an
                                     Exempted Party, as defined below, acquires beneficial ownership of 15%
                                     or more of the Company's Common Stock or (b) the tenth business day
                                     (or such later date as may be determined by the Company's Board of
                                     Directors) after a person or group, other than Exempted Party, announces
                                     a tender or exchange offer, the consummation of which would result in
                                     ownership by a person or group of 15% or more of the Company's
                                     Common Stock.

Exempted Parties:                    Vinod Gupta, and entities controlled by or established for the benefit of
                                     Vinod Gupta or any of his immediate family members.

Preferred Stock                      After the Distribution Date, each Right will entitle the holder
Purchasable Upon                     to purchase for $60.00 (the "EXERCISE PRICE"), a fraction of a
Exercise of Rights:                  share of Company's Preferred Stock with economic terms
                                     similar to that of one share of the Company's Common Stock.

Flip-In:                             If an acquiror, other than an Exempted Party, (an "ACQUIRING PERSON")
                                     obtains 15% or more of the Company's Common Stock then each Right
                                     (other than Rights owned by an Acquiring Person or its affiliates) will
                                     entitle the holder thereof to purchase, for the Exercise Price, a number of
                                     shares of the Company's Common Stock having a then current market
                                     value of twice the Exercise Price.

Flip-Over:                           If, after an Acquiring Person obtains 15% or more of the Company's Common
                                     Stock, (a) the Company merges into another entity, (b) an acquiring entity
                                     merges into the Company or (c) the Company sells more than 50% of the Company's
                                     assets or earning power, then each Right (other than Rights owned by an Acquiring
                                     Person or its affiliates) will

                                     shares of Common Stock of the person engaging in the transaction having a
                                     then current market value of twice the Exercise Price.

Redemption of                        Rights will be redeemable at the Company's option for $0.001 per Right
the Rights:                          at any time on or prior to public announcement that a Person has acquired
                                     beneficial ownership of 15% or more of the Company's Common Stock (the "SHARES
                                     ACQUISITION DATE").

Expiration of                        The Rights expire on the earliest of (a) July 21, 2007 or  (b) redemption
the Rights:                          of the Rights as described above.

Amendment of                         The terms of the Rights and the Rights Agreement may be amended in any
Terms of Rights:                     respect without the consent of the Rights holders on or prior to the
                                     Distribution Date; thereafter, the terms of the Rights and the Rights
                                     Agreement may be amended without the consent of the Rights holders in order
                                     to cure any ambiguities or to make changes which do not adversely affect the
                                     interests of Rights holders (other than the Acquiring Person).

Voting Rights:                       Rights will not have any voting rights.

Anti-Dilution                        Rights will have the benefit of certain customary anti-dilution
Provisions:                          provisions.

Taxes:                               The Rights distribution should not be taxable for federal income tax
                                     purposes. However, following an event which renders the Rights
                                     exercisable or upon redemption of the Rights, stockholders may recognize
                                     taxable income.
