The Board of Directors is hereby expressly authorized, by resolution or
resolutions, to provide for the issuance of up to 500,000,000 shares of
Preferred Stock in one or more series and, by filing a certificate pursuant to
the Delaware Code (hereinafter referred to as a "Preferred Stock Designation"),
to establish from time to time the number of shares constituting each such
series and the designation of such series, the voting powers (if any) of the
shares of such series, and the relative rights, powers, privileges, preferences
and limitations of the shares of such series. The authority of the Board of
Directors with respect to each series shall include, but not be limited to,

Directors may thereafter (except where otherwise provided in the Preferred Stock
Designation) increase or decrease, but not below the number of shares thereof
then outstanding) in the manner permitted by law;

         (c) the rate of any dividends (or method of determining the dividends)
payable to the holders of the shares of such series, any conditions upon which
such dividends shall be paid and the date or dates or the method for determining

<PAGE>   3

         (d) whether dividends, if any, shall be cumulative or noncumulative,
and, in the case of shares of any series having cumulative dividend rights, the
date or dates or method of determining the date or dates from which dividends on
the shares of such series shall cumulate;

         (e) if the shares of such series may be redeemed by the Corporation,
the price or prices (or method of determining such price or prices) at which,
the form of payment of such price or prices (which may be cash, property or
rights, including securities of the Corporation or of another corporation or
other entity) for which, the period or periods within which and the other terms
and conditions upon which the shares of such series may be redeemed, in whole or
in part, at the option of the Corporation or at the option of the holder or
holders thereof or upon the happening of a specified event or events, if any,
including the obligation, if any, of the Corporation to purchase or redeem
shares of such series pursuant to a sinking fund or otherwise;

         (f) the amount payable out of the assets of the Corporation to the
holders of shares of the series in the event of any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Corporation;

         (g) provisions, if any, for the conversion or exchange of the shares of
such series, at any time or times, at the option of the holder or holders
thereof or at the option of the Corporation or upon the happening of a specified
event or events, into shares of any other class or classes or any other series
of the same class of capital stock of the Corporation or into any other security
of the Corporation, or into the stock or other securities of any other
corporation or other entity, and the price or prices or rate or rates of
conversion or exchange and any adjustments applicable thereto, and all other

the series.

     Shares of Preferred Stock, regardless of series, that are converted into

designation as to series.

SECTION 3. Common Stock.

A.   Voting Rights.

     Subject to applicable law and the rights of any outstanding series of
Preferred Stock to vote as a separate class or series, the shares of Class A
Common Stock and Class B Common Stock shall vote together as a single class and
shall have the following voting rights: (i) each share of Class A Common Stock
shall entitle the holder thereof to one (1) vote upon all matters upon which
stockholders shall have the right to vote; and (ii) each share of Class B Common
Stock shall entitle the holder thereof to ten (10) votes upon all matters upon
which stockholders shall have the right to vote, subject to Section 3.E.8. of
this Article IV. The authorized number of shares of Class A Common Stock may be
increased or decreased (but not below the number of shares thereof then
outstanding or reserved for issuance upon conversion of the Class B Common Stock
or any other class or series of outstanding Stock) by the affirmative vote of
the holders of Common Stock entitled to cast a majority of the total votes
entitled to be cast by the holders of the Common Stock, voting as a single
class, without a separate class vote of the holders of the Class A Common Stock.
The Corporation may, as a condition to counting the votes cast by any holder of
shares of Class B Common Stock, require proof as set forth in Section 3.E.8 of
this Article IV that the shares of Class B Common Stock held by such holder have
not been converted into shares of Class A Common Stock. Except as otherwise
provided by law or by another provision of this Restated Certificate of
Incorporation or by a Preferred Stock Designation, the Common Stock shall have
the exclusive right to vote for the election of directors and on all other
matters or proposals presented to the stockholders and all matters to be voted
on by stockholders must be approved by a majority of the outstanding shares
entitled to vote; provided, however, that the holders of shares of Common Stock,
as such, shall not be entitled to vote on any amendment of this Restated
Certificate of Incorporation (including any amendment of any provision of a
Preferred Stock Designation) that solely relates to the powers, privileges,
preferences or rights pertaining to one or more outstanding series of Preferred
Stock, or the number of shares of any such series, and does not affect the
number of authorized shares of Preferred Stock or the powers, privileges and
rights pertaining to the Common Stock, if the holders of any of such series of
Preferred Stock are entitled, separately or together with the holders of any
other series of Preferred Stock, to vote thereon pursuant to this Restated
Certificate of Incorporation (including any Preferred Stock Designation) or
pursuant to the Delaware Code, unless a vote of holders of shares of Common
Stock is otherwise


                                       4
<PAGE>   5

required by any provision of the Preferred Stock Designation for any such series
or any other provision of this Restated Certificate of Incorporation fixing the
powers, privileges, and rights of any such series or the qualifications,
limitations or restrictions thereon or is otherwise required by law. Holders of
Preferred Stock of any series shall not be entitled to receive notice of any
meeting of stockholders at which they are not entitled to vote, except as may be
explicitly provided by any Preferred Stock Designation. The number of authorized
shares of Preferred Stock may be increased or decreased (but not below the
number of shares thereof then outstanding) by the affirmative vote of the
holders of a majority of the outstanding shares of Common Stock, without a vote
of the holders of the Preferred Stock, or any series thereof, unless a vote of
any such holders is required pursuant to another provision of this Restated
Certificate of Incorporation (including any Preferred Stock Designation). Except
as otherwise provided by law or in this Restated Certificate of Incorporation,
and subject to any voting rights granted to holders of any outstanding Preferred
Stock, amendments to this Restated Certificate of Incorporation must be approved
by a majority of the votes entitled to be cast by all shares of Class A Common
Stock and Class B Common Stock, voting together as a single class, provided,
however, that any amendment to this Restated Certificate of Incorporation that
would alter or change the powers, preferences or special rights of the Class A
Common Stock so as to affect them adversely also must be approved by a majority
of the votes entitled to be cast by the holders of the Class A Common Stock,
voting as a separate class. Any amendment to this Restated Certificate of
Incorporation to increase the authorized shares of any class requires the
approval only of a majority of the votes entitled to be cast by all shares of
Class A Common Stock and Class B Common Stock, voting together as a single
class, subject to the rights set forth in any series of Preferred Stock. Holders
of shares of Common Stock are not entitled to cumulate their votes in the
election of directors.

B.   Dividends and Distributions.

     Subject to the preferential and other dividend rights of any outstanding
series of Preferred Stock, holders of Class A Common Stock and Class B Common
Stock shall be entitled to such dividends and other distributions in cash, stock
or property of the Corporation as may be declared thereon by the Board of
Directors from time to time out of assets or funds of the Corporation legally
available therefor. No dividend or other distribution may be declared or paid on
any share of Class A Common Stock unless a like dividend or other distribution
is simultaneously declared or paid, as the case may be, on each share of Class B
Common Stock, nor shall any dividend or other distribution be declared or paid
on any share of Class B Common Stock unless a like dividend or other
distribution is simultaneously declared or paid, as the case


                                       5
<PAGE>   6

may be, on each share of Class A Common Stock, in each case without preference
or priority of any kind; provided, however, that all dividends and distributions
on the Class A Common Stock and Class B Common Stock payable in shares of Common
Stock of the Corporation shall be made in shares of Class A Common Stock and
Class B Common Stock, respectively. In no event will shares of either class of
Common Stock be reclassified, split, divided or combined unless the outstanding
shares of the other class of Common Stock shall be proportionately reclassified,
split, divided or combined.

     In the event of a transaction as a result of which the shares of Class A
Common Stock are converted into or exchanged for one or more other securities,
cash or other property (a "Class A Conversion Event"), then from and after such
Class A Conversion Event, a holder of Class B Common Stock shall be entitled to
receive, upon the conversion of such Class B Common Stock pursuant to Section
3.E. of this Article IV, the amount of such securities, cash and other property
that such holder would have received if the conversion of such Class B Common
Stock had occurred immediately prior to the record date (or if there is no
record date, the effective date) of the Class A Conversion Event and if the
securities, cash or other property that the Class A Common Stock may be
converted into or exchanged for in a Class A Conversion Event is dependent upon
the holder of the Class A Common Stock making an election, the holder of the
Class A Common Stock had failed to make an election. This paragraph shall be
applicable in the same manner to all successive conversions or exchanges of
securities issued pursuant to any Class A Conversion Event. No adjustments in
respect of dividends shall be made upon the conversion of any share of Class B
Common Stock; provided, however, that if a share shall be converted after the
record date for the payment of a dividend or other distribution on shares of
Class B Common Stock but before such payment, then the record holder of such
share at the close of business on such record date shall be entitled to receive
the dividend or other distribution payable on such share of Class B Common Stock
on the payment date notwithstanding the conversion thereof.

C.   Options, Rights or Warrants.

     Subject to Section 3.B. of this Article IV, the Corporation shall not, and
shall not be entitled to, issue additional shares of Class B Common Stock, or
issue options, rights or warrants to subscribe for or purchase additional shares
of Class B Common Stock, except that the Corporation may (i) make a pro rata
offer to all holders of Common Stock of rights to subscribe for additional
shares of the class of Common Stock held by them and (ii) issue additional
shares of Class B Common Stock under the circumstances permitted by the
Separation Agreement (the "Separation


                                       6
<PAGE>   7

Agreement"), dated as of        , 1999, between the Corporation and The Williams
Companies, Inc. ("Williams"). The Corporation may make offerings of options,
rights or warrants to subscribe for or purchase shares of any class or classes
of capital stock (other than Class B Common Stock) to all holders of Class A
Common Stock or Class B Common Stock if an identical offering is made
simultaneously to all the holders of the other class of Common Stock. All
offerings of options, rights or warrants shall offer the respective holders of
Class A Common Stock and Class B Common Stock the right to subscribe or purchase
at the same consideration per share.


D.   Merger or Consolidation.

     In the event of a merger or consolidation of the Corporation with or into
another entity (whether or not the Corporation is the surviving entity), the
holders of each share of Class A Common Stock and Class B Common Stock shall be
entitled to receive the same per share consideration as the per share
consideration, if any, received by the holders of each share of the other class
of Common Stock; provided that, if such consideration shall consist in any part
of voting securities (or of options, rights or warrants to purchase, or of
securities convertible into or exchangeable for, voting securities), then the
Corporation may provide in the applicable merger or such other agreement for the
holders of shares of Class B Common Stock to receive, on a per share basis,
voting securities with ten (10) times the number of votes per share as those
voting securities to be received by the holders of shares of Class A Common
Stock (or options, rights or warrants to purchase, or securities convertible
into or exchangeable for, voting securities with ten (10) times the number of
votes per share as those voting securities issuable upon exercise of the
options, rights or warrants to be received by the holders of the shares of Class
A Common Stock, or into which the convertible or exchangeable securities to be
received by the holders of the shares of Class A Common Stock may be converted
or exchanged).

E.   Conversion of Class B Common Stock.

         1. Voluntary Conversion.

            Prior to the date on which shares of Class B Common Stock are
         transferred to stockholders of Williams in a Tax-Free Spin-Off (as
         defined in paragraph (E) (3)(a) below), each share of Class B Common
         Stock shall be convertible, at the option of its record holder, into
         one validly issued, fully paid and non-assessable share of Class A
         Common Stock at any time. Following a Tax-Free Spin-Off, shares


                                       7
<PAGE>   8

         of Class B Common Stock shall no longer be convertible into shares of
         Class A Common Stock.

         2. Voluntary Conversion Procedures.

            At the time of a voluntary conversion, the record holder of shares
         of Class B Common Stock shall deliver to the principal office of the
         Corporation or any transfer agent for shares of the Class A Common
         Stock (i) the certificate or certificates representing the shares of
         Class B Common Stock to be converted, duly endorsed in blank or
         accompanied by proper instruments of transfer, and (ii) written notice
         to the Corporation stating that the record holder elects to convert
         such share or shares and stating the name or names and denominations in
         which the certificate or certificates representing the shares of Class
         A Common Stock issuable upon the conversion are to be issued and
         including instructions for the delivery thereof. Conversion shall be
         deemed to have been effected at the time when delivery is made to the
         principal office of the Corporation or the office of any transfer agent
         for shares of Class A Common Stock of such written notice and the
         certificate or certificates representing the shares of Class B Common
         Stock to be converted, and as of such time, each Person (as hereinafter
         defined) named in such written notice as the Person to whom a
         certificate representing shares of Class A Common Stock is to be issued
         shall be deemed to be the holder of record of the number of shares of
         Class A Common Stock to be evidenced by that certificate. Upon such
         delivery, the Corporation or its transfer agent shall promptly issue
         and deliver a certificate or certificates representing the number of
         shares of Class A Common Stock to which such record holder is entitled
         by reason of such conversion, and shall cause such shares of Class A
         Common Stock to be registered in the name of the record holder.

         3. Automatic Conversion.

            (a) Subject to Section 3.E.3.(b) of this Article IV, prior to a
         Tax-Free Spin-Off, in the event of any Transfer (as hereinafter
         defined) of any share of Class B Common Stock to any Person, other than
         to the Williams Group (as defined in paragraph (E)(9) below) such share
         of Class B Common Stock shall automatically, without any further
         action, convert into one share of Class A Common Stock.


                                       8
<PAGE>   9

         Notwithstanding anything to the contrary set forth in this Restated
         Certificate of Incorporation, shares of Class B Common Stock shall not
         convert into shares of Class A Common Stock (i) in any transfer
         effected in connection with a distribution of Class B Common Stock to
         stockholders or security holders of Williams in a transaction
         (including any distribution in exchange for shares of capital stock or
         securities of Williams) intended to qualify as a tax-free distribution
         under Section 355 of the Internal Revenue Code of 1986, as amended (the
         "Code"), or any successor provision (a "Tax-Free Spin-Off") or (ii) in
         any transfer after a Tax-Free Spin-Off. For purposes of this paragraph
         (E), a Tax-Free Spin-Off shall be deemed to have occurred at the time
         shares are first transferred to stockholders or security holders of
         Williams.

            (b) Notwithstanding anything to the contrary set forth in this
         Article IV, Section 3, a holder of shares of Class B Common Stock may
         pledge such holder's shares of Class B Common Stock to a financial
         institution pursuant to a bona fide pledge of such shares of Class B
         Common Stock as collateral security for any indebtedness or other
         obligation of any Person (the "Pledged Stock") due to the pledgee or
         its nominee; provided, however, that (i) such shares shall not be voted
         by or registered in the name of the pledgee and shall remain subject to
         the provisions of this Article IV, Section 3.E. and (ii) upon any
         foreclosure, realization or other similar action by the pledgee prior
         to a Tax-Free Spin-Off, such Pledged Stock shall automatically convert
         into shares of Class A Common Stock on a share-for-share basis.

            (c) The foregoing automatic conversion events described in this
         Article IV, Section 3.E.3 shall be referred to hereinafter as an "Event
         of Automatic Conversion." The determination of whether an Event of
         Automatic Conversion shall have occurred will be made by the Board of
         Directors or a duly authorized committee thereof in accordance with
         Article IV, Section 3.E.8 below.

         4. Automatic Conversion Procedure.

            Any conversion pursuant to an Event of Automatic Conversion shall be
         deemed to have been effected at the time the


                                       9
<PAGE>   10

         Event of Automatic Conversion occurred (the "Conversion Time"). At the
         Conversion Time, the certificate or certificates that represented
         immediately prior thereto the shares of Class B Common Stock that were
         so converted (the "Converted Class B Common Stock") shall,
         automatically and without further action, represent the same number of
         shares of Class A Common Stock. Holders of Converted Class B Common
         Stock shall deliver their certificates, duly endorsed in blank or
         accompanied by proper instruments of transfer, to the principal office
         of the Corporation or the office of any transfer agent for shares of
         the Class A Common Stock, together with a written notice setting out
         the name or names (with addresses) and denominations in which the
         certificate or certificates representing such shares of Class A Common
         Stock are to be issued and including instructions for delivery thereof.
         Upon such delivery, the Corporation or its transfer agent shall
         promptly issue and deliver at such stated address to such holder of
         shares of Class A Common Stock a certificate or certificates
         representing the number of shares of Class A Common Stock to which such
         holder is entitled by reason of such conversion, and shall cause such
         shares of Class A Common Stock to be registered in the name of such
         holder. The Person entitled to receive the shares of Class A Common
         Stock issuable upon such conversion shall be treated for all purposes
         as the record holder of such shares of Class A Common Stock at and as
         of the Conversion Time, and the rights of such Person as a holder of
         shares of Class B Common Stock that have been converted shall cease and
         terminate at and as of the Conversion Time, in each case without regard
         to any failure by such holder to deliver the certificates or the notice
         required by this Section.

         5. Unconverted Shares.

            In the event of the conversion of less than all the shares of Class
         B Common Stock evidenced by a certificate surrendered to the
         Corporation in accordance with the procedures of this Section 3.E., the
         Corporation shall execute and deliver to, or upon the written order of,
         the holder of such unconverted shares, without charge to such holder, a
         new certificate evidencing the number of shares of Class B Common Stock
         not converted.


                                       10
<PAGE>   11

         6. Retired Shares.

            Shares of Class B Common Stock that are converted into shares of
         Class A Common Stock as provided herein shall be retired and canceled
         and the Corporation shall take all such actions as are necessary to
         cause such shares to have the status of authorized but unissued shares
         of Class B Common Stock.

         7. Reservation.

            The Corporation shall at all times prior to a Tax-Free Spin-Off
         reserve and keep available, out of its authorized and unissued shares
         of Class A Common Stock, for the purposes of effecting conversions,
         such number of duly authorized shares of Class A Common Stock as shall
         from time to time be sufficient to effect the conversion of all
         outstanding shares of Class B Common Stock. All the shares of Class A
         Common Stock so issuable shall, when so issued, be duly and validly
         issued, fully paid and non-assessable and free from liens and charges
         with respect to such issuance.

         8. Determination of Voting Rights and Event of Automatic Conversion.

            The Board of Directors of the Corporation or a duly authorized
         committee thereof shall have the power to determine, in good faith
         after reasonable inquiry, whether an Event of Automatic Conversion has
         occurred with respect to any share of Class B Common Stock. A
         determination by the Board of Directors of the Corporation or such
         committee that an Event of Automatic Conversion has occurred shall be
         conclusive. As a condition to counting the votes cast by any holder of
         shares of Class B Common Stock at any annual or special meeting of
         stockholders, in connection with any written consent of stockholders,
         as a condition to registration of transfer of shares of Class B Common
         Stock, or for any other purpose, the Board of Directors or a duly
         authorized committee thereof, in its discretion, may require the holder
         of such shares to furnish such affidavits or other proof as the Board
         of Directors or such committee deems necessary or advisable to
         determine whether an Event of Automatic Conversion shall have occurred.
         If the Board of Directors or such committee shall determine that a
         holder has substantially failed to comply promptly with any request by
         the Board of Directors or such committee for such proof, the shares
         held by such holder shall be

         entitled to one (1) vote per share until such time as the Board of
         Directors or such committee shall determine that such holder has
         complied with such request. The Board of Directors or a duly authorized
         committee thereof may exercise the authority granted by this Article
         IV, Section 3.E.8 through duly authorized officers or agents of the
         Corporation.

                        Purchase of Shares by Corporation

Corporation or the right to purchase any such shares of capital stock from any
holder thereof on terms and conditions established by the Board of Directors or
a duly authorized committee thereof.

                               Board of Directors

SECTION 1. Number and Terms.

     Except as otherwise fixed by or pursuant to the provisions of this Restated
Certificate of Incorporation relating to the rights of the holders of any class
or series of Preferred Stock, the number of directors of the Corporation shall
be determined by resolution adopted by a majority of the entire Board of
Directors, but the number shall not be less than three; provided, however, that
(i) no reduction in the number of directors shall end the term of office of any
incumbent director prior to the date such director's term of office would
otherwise end, and (ii) the By-laws of the Corporation (the "By-laws") may
provide that the vote of a greater number of the directors may be required for
action of the Board of Directors changing the size of the Board of Directors.
The directors, other than those who may be elected by the holders of any class
or series of Preferred Stock, shall be classified by the Board of Directors with
respect to the time for which they severally hold office, into three classes, as
nearly equal in number as possible, one class to be originally elected for a
term expiring at the annual meeting of stockholders to be held in 2000, another
class to be originally elected for a term expiring at the annual meeting of
stockholders to be held in 2001, and another class to be originally elected for
a term expiring at the annual meeting of stockholders to be held in 2002. Each
director of the Corporation shall hold office until his or her successor is duly
elected and qualified, such classification to be effective upon the date shares
of Class A Common Stock are first publicly held. At each succeeding annual
meeting of stockholders, directors elected to succeed those directors whose
terms then expire shall be elected for a term of office to expire at the third
annual meeting of stockholders following such director's election and until such
director's successor shall have been elected and qualified. No decrease in the
number of directors shall shorten the term of any incumbent director. Unless and
except to the extent that the By-laws shall so require, the election of
directors need not be by written ballot.

SECTION 2. Vacancies.

     Except as otherwise provided for or fixed by or pursuant to the provisions
of this Restated Certificate of Incorporation relating to the rights of the

of the Corporation resulting from death, resignation, removal or other cause and
any newly created directorship resulting from any increase in the authorized
number of directors between meetings of stockholders shall be filled only by the
affirmative vote of (i) at least 66 and 2/3% of the remaining directors then in
office if prior to the Trigger Date, or (ii) a majority of all the directors
then in office, even though less than a quorum if on or after the Trigger Date,
but in any event not by the stockholders. Any director so chosen shall hold
office for the remainder of the full term of the class of directors in which the
vacancy occurred or the new directorship was created and until a successor is
duly elected and qualified or until his or her earlier death, resignation or
removal from office in accordance with this Restated Certificate of
Incorporation or any applicable law or pursuant to an order of a court. If there
are no directors in office, then an election of directors may be held in the
manner provided by applicable law.

affirmative vote of the holders of a majority of the combined voting power of
the then-outstanding shares of stock of the Corporation entitled to vote for the
election of directors, voting together as a single class, and (ii) on and after
the Trigger Date, any director may be removed from office only for cause by the
affirmative vote of the holders of at least a majority of the combined voting
power of the then-outstanding shares of stock of the Corporation entitled to
vote for the election of directors, voting together as a single class.

SECTION 5. Amendment of this Article.

Restated Certificate of Incorporation, the affirmative vote of the holders of at
least 66 and 2/3%


                                       16
<PAGE>   17

SECTION 1. Action by Consent in Lieu of a Meeting.

     Effective upon and commencing as of the day following the day on which
Williams, and any company that is directly or indirectly controlled by Williams
and of which at least a majority of the equity interests therein are directly or
indirectly beneficially owned by Williams shall first cease to be the owner, in
the aggregate, of at least a majority of the then-outstanding shares of Common
Stock (the "Trigger Date"), and except as otherwise provided pursuant to the
provisions of this Restated Certificate of Incorporation (including any
Preferred Stock Designation) fixing the powers, privileges or rights of any
class or series of stock other than the Common Stock in respect of action by
written consent of the holders of such class or series of stock, any action
required or permitted to be taken by the stockholders of the Corporation must be
effected at a duly called annual or special meeting of such holders and may not
be effected by any consent in writing by such holders. Prior to the Trigger
Date, the By-laws may provide that any action required to be taken at any
meeting of stockholders may be taken without a meeting, without prior notice and
without a vote, if a consent in writing, setting forth the action so taken,
shall be signed by the holders of shares of outstanding stock having not less
than the minimum number of votes that would be necessary to authorize or take
such action at a meeting at which all shares of stock entitled to vote were
present and voted, provided that prompt notice of the taking of the corporation
action without a meeting by less than unanimous written consent shall be given
to those stockholders who have not consented in writing.

SECTION 2. Meetings.

     Effective upon and commencing as of the Trigger Date, except as otherwise
required by law and subject to the rights of the holders of any class or series
of Preferred Stock, special meeting of stockholders of the Corporation of any

series for any purpose or purposes may be called only by the Board of Directors
pursuant to a resolution stating the purpose or purposes thereof approved by a
majority of the entire Board of Directors and, effective as of the Trigger Date,
any power of stockholders to call a special meeting is specifically denied. No
business other than that stated in the notice shall be transacted at any special
meeting.

     Prior to the Trigger Date, subject to the rights of the holders of any
outstanding series of Preferred Stock, special meetings of stockholders of the
Corporation may be called only by the Secretary of the Corporation at the
request of Williams or its affiliates.

     Notwithstanding the foregoing, whenever the holders of any one or more
outstanding series of Preferred Stock shall have the right, voting separately by
class or series, as applicable, to elect directors at an annual or special
meeting of stockholders, the calling of special meetings of the holders of such
class or series shall be governed by the terms of the applicable resolution or
resolutions of the Board of Directors establishing such series of Preferred
Stock pursuant to Article IV of this Restated Certificate of Incorporation.

     The Board of Directors shall have the power to adopt, alter, amend or
repeal the By-laws. The stockholders of the Corporation may adopt, amend or
repeal the By-laws but only by the affirmative vote of holders of at least a
majority of the combined voting power of the then-outstanding shares of capital
stock of all classes and series of the Corporation entitled to vote generally on
matters requiring the approval of stockholders, voting together as a single
class.

                                   ARTICLE IX

Incorporation, and any other provisions authorized by the laws of the State of
Delaware at the time in force may be added or inserted, in the manner now or
hereafter prescribed by law; and all rights, preferences and privileges of

                                    ARTICLE X

                    Indemnification; Limitation of Liability.

SECTION 1. Indemnification.

A. Each person who was or is made a party or is threatened to be made a party to
or is otherwise involved in any action, suit, or proceeding, whether civil,
criminal, administrative, or investigative (hereinafter a "proceeding"), by
reason of the fact that he or she is or was a director of the Corporation or any
of its direct or indirect subsidiaries or is or was serving at the request of
the Corporation as a director of any other corporation or of a partnership,
limited liability company, joint venture, trust, or other enterprise, including
service with respect to an employee benefit plan (hereinafter an "indemnitee"),
whether the basis of such proceeding is alleged action in an official capacity
as a director or in any other capacity while serving as a director, shall be
indemnified and held harmless by the Corporation to the fullest


                                       19
<PAGE>   20

extent authorized by the Delaware Code, as the same exists or may hereafter be
amended (but, in the case of any such amendment, only to the extent that such
amendment permits the Corporation to provide broader indemnification rights than
permitted prior thereto), against all expense, liability, and loss (including
attorneys' fees, judgments, fines, excise or other taxes assessed with respect
to an employee benefit plan, penalties, and amounts paid in settlement)
reasonably incurred or suffered by such indemnitee in connection therewith, and
such indemnification shall continue as to an indemnitee who has ceased to be a
director and shall inure to the benefit of the indemnitee's heirs, executors,
and administrators; provided, however, that, except as provided in Paragraph B
of this Section 1 with respect to proceedings to enforce rights to
indemnification, the Corporation shall indemnify any such indemnitee in
connection with a proceeding (or part thereof) initiated by such indemnitee only
if such proceeding (or part thereof) was authorized by the Board of Directors of
the Corporation.

B. The right to indemnification conferred in Paragraph A of this Section 1 shall
include the right to be paid by the Corporation the expenses incurred in
defending any proceeding for which such right to indemnification is applicable
in advance of its final disposition (hereinafter an "advancement of expenses");
provided, however, that, if the Delaware Code requires, an advancement of
expenses incurred by an indemnitee in his or her capacity as a director (and not
in any other capacity in which service was or is rendered by such indemnitee,
including, without limitation, service to an employee benefit plan) shall be
made only upon delivery to the Corporation of an undertaking (hereinafter an
"undertaking"), by or on behalf of such indemnitee, to repay all amounts so
advanced if it shall ultimately be determined by final judicial decision from
which there is no further right to appeal (hereinafter a "final adjudication")
that such indemnitee is not entitled to be indemnified for such expenses under
this Section 1 or otherwise.

C. The rights to indemnification and to the advancement of expenses conferred in
Paragraphs A and B of this Section 1 shall be contract rights. If a claim under
Paragraph A or B of this Section 1 is not paid in full by the Corporation within
60 days after a written claim has been received by the Corporation, except in
the case of a claim for an advancement of expenses, in which case the applicable
period shall be 20 days, the indemnitee may at anytime thereafter bring suit
against the Corporation to recover the unpaid amount of the claim. If successful
in whole or in part in any such suit, or in a suit brought by the Corporation to
recover an advancement of expenses pursuant to the terms of an undertaking, the
indemnitee shall be entitled to be paid also the expense of prosecuting or
defending such suit. In (i) any suit brought by the indemnitee to enforce a
right to indemnification hereunder (but not in a suit


                                       20
<PAGE>   21

brought by an indemnitee to enforce a right to an advancement of expenses) it
shall be a defense that the indemnitee has not met any applicable standard for
indemnification set forth in the Delaware Code, and (ii) any suit by the
Corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the Corporation shall be entitled to recover such expenses upon a
final adjudication that the indemnitee has not met any applicable standard for
indemnification set forth in the Delaware Code. Neither the failure of the
Corporation (including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
the Delaware Code, nor an actual determination by the Corporation (including its
Board of Directors, independent legal counsel, or its stockholders) that the
indemnitee has not met such applicable standard of conduct, shall create a
presumption that the indemnitee has not met the applicable standard of conduct
or, in the case of such a suit brought by the indemnitee to enforce a right to
indemnification or to an advancement of expenses hereunder, or by the
Corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the burden of proving that the indemnitee is not entitled to be
indemnified, or to such advancement of expenses, under this Section 1 or
otherwise, shall be on the Corporation.

D. The rights to indemnification and to the advancement of Expenses conferred in
this Section 1 shall not be exclusive of any right which any person may have or
hereafter acquire under any statute, this certificate of incorporation, by-law,
agreement, vote of stockholders or disinterested directors, or otherwise.

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

F. The Corporation's obligation, if any, to indemnify any person who was or is
serving as a director of any direct or indirect subsidiary of the Corporation
or, at the request of the Corporation, of any other corporation or of a
partnership, joint venture, trust, or other enterprise shall be reduced by any
amount such person may collect as indemnification from such other corporation,
partnership, joint venture, trust or other enterprise.

G. Any repeal or modification of the foregoing provisions of this Section 1
shall


                                       21
<PAGE>   22

not adversely affect any right or protection hereunder of any person in respect
of any act or omission occurring prior to the time of such repeal or
modification.

H. The Corporation may, to the extent authorized from time to time by the Board
of Directors, grant indemnification rights and rights to the advancement of
expenses to any officer, employee or agent of the Corporation to the fullest
extent of the provision of this Article with respect to the indemnification and
advancement of expenses to directors.

SECTION 2. Limited Liability.

     No director of the Corporation shall be liable to the Corporation or any of
its stockholders for monetary damages for breach of fiduciary duty as a
director, provided that this provision does not eliminate the liability of the
director (i) for any breach of the director's duty of loyalty to the Corporation
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of Title B of the Delaware Code, or (iv) for any transaction from
which the director derived an improper personal benefit. For purposes of the
prior sentence, the term "damages" shall, to the extent permitted by law,
include without limitation, any judgment, fine amount paid in settlement,
penalty, punitive damages, excise or other tax assessed with respect to an
employee benefit plan, or expense of any nature (including, without limitation,
counsel fees and disbursements). Each person who serves as a director of the
Corporation while this Section 2 is in effect shall be deemed to be doing so in
reliance on the provisions of this Section 2, and neither the amendment or
repeal of this Section 2, nor the adoption of any provision of this Restated
Certificate of Incorporation inconsistent with this Section 2, shall apply to or
have any effect on the liability or alleged liability of any director of the
Corporation for, arising out of, based upon, or in connection with any acts or
omissions of such director occurring prior to such amendment, repeal, or
adoption of an inconsistent provision. The provisions of this Section 2 are
cumulative and shall be in addition to and independent of any and all other
limitations on or eliminations of the liabilities of directors of the
Corporation, as such, whether such limitation or eliminations arise under or are
created by any law, rule, regulation, by-law, agreement, vote of stockholders or
disinterested directors, or otherwise.

     Subject to Section 4 of this Article XI, neither Williams nor any
Affiliated Company thereof, as a stockholder of the Corporation or participant
in control of the Corporation, shall have or be under any fiduciary duty to
refrain from entering into any agreement or participating in any transaction
that meets the requirements of any of clauses (i), (ii), (iii), (iv), (v), (vi)
or (vii) of the immediately preceding sentence and no director, officer or
employees of the Corporation who is also a director, officer or employee of
Williams or any Affiliated Company thereof shall have or be under any fiduciary
duty to the Corporation to refrain from acting on behalf of the Corporation or
any Affiliated Company thereof in respect of any such agreement or transaction
or performing any such agreement in accordance with its terms. Directors of the
Corporation who are also directors or officers of Williams or any Affiliated
Company may be counted in determining the presence of a quorum at a meeting of
the Board of Directors or of a committee which authorizes the contract,
agreement, arrangement, or transaction (or the amendment, modification or
termination thereof). Voting stock owned by Williams and any Affiliated
Companies thereof may be counted in determining the presence of a quorum at a
meeting of stockholders which authorizes the contract, agreement, arrangement or
transaction. Any person purchasing or otherwise acquiring any shares of capital
stock of the Corporation, or any interest therein, shall be deemed to have
notice of and to have consented to the provisions of this Article. The failure
of any agreement or transaction between the Corporation or an Affiliated Company
thereof, on the one hand, and Williams or an Affiliated Company thereof, on the
other hand, to satisfy the requirements of this Section shall not, by itself,
cause such agreement or transaction to constitute any breach of any fiduciary
duty to the Corporation or to any Affiliated Company thereof, or, any to
stockholder or other owner of an equity interest therein, by any controlling
stockholder of the Corporation or such Affiliated Company thereof or by any
director or officer of the Corporation.

     For purposes of this Article XI, Section 2., any contract, agreement,
arrangement, or transaction (or amendment, modification, or termination thereof)
with any corporation, partnership, joint venture, association, or other entity
in which the Corporation owns (directly or indirectly) 50% or more of the
outstanding voting stock, voting power, partnership interests, or similar
ownership interests, or with any officer or director thereof, shall be deemed to
be a contract, agreement, arrangement or transaction with the Corporation.

SECTION 3. Certain Definitions.

     For purposes of this Article, the following definitions shall apply:


     "Affiliated Company" shall mean in respect of Williams, any company which
is controlled by Williams controls Williams or is under common control with
Williams (other than the Corporation and any company that is controlled by the
Corporation) and in respect of the Corporation shall mean any company controlled
by the Corporation.

     "Interested Person" in respect of an agreement or transaction referred to
in Section 2 of this Article XI shall mean any director, officer or employees of
Williams or an Affiliated Company thereof and any person who has a financial
interest that is material to such person in Williams or such Affiliated Company
or otherwise has a personal financial interest that is material to such person
in such agreement or transaction; provided, however, that no such financial
interest shall be considered material by reason of a person' ownership of
securities of Williams or an Affiliated Company thereof, if such ownership of
securities has been determined in good faith not to be reasonably likely to
influence such individual's decision on behalf of the Corporation or an
Affiliated Company thereof in respect of the agreement or transaction either in
the specific instance by, or pursuant to, a policy adopted by, the Board of
Directors of the Corporation by the affirmative vote of a majority of the
members (even though less than a quorum) who are not directors, officers or
employees of Williams or any Affiliated Company thereof or a committee of the
Board of Directors of the Corporation constituted solely of members who are not
directors, officers or employees of Williams or any Affiliated Company thereof
by the affirmative vote of a majority of such committee.

SECTION 4. Termination.

     The provisions of this Article XI shall have no further force or effect at
such time as Williams and any company controlling, controlled by or under common
control with Williams shall first cease to be the owner, in the aggregate, of
stock representing 25% or more of the votes entitled to be cast by the holders
of all the then-outstanding shares of stock entitled to vote; provided, however,
that such termination shall not terminate the effect of such provisions with
respect to (i) any agreement between the Corporation or an Affiliated Company
thereof and Williams or an Affiliated Company thereof that was entered into
before such time or any transaction entered into in the performance of such
agreement, whether entered into before or after such time, or (ii) any
transaction entered into between the Corporation or an Affiliated Company
thereof and Williams or an Affiliated Company thereof or the allocation of any
opportunity between them before such time.

SECTION 5. Amendment of this Article.

     Notwithstanding anything to the contrary elsewhere contained in this
Restated Certificate of Incorporation, the affirmative vote of the holders of at
least 66 and 2/3% of the combined voting power of the then-outstanding shares of
stock of the Corporation entitled to vote for the election of directors, voting
together as a single class, shall be required to alter, amend or repeal, or to
adopt any provision inconsistent with, this Article XI.

par value $0.01 per share, of the Corporation (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 Junior Participating Preferred Stock. In the
event the Corporation shall at any time after September 30, 1999 (the "Rights
Declaration Date") (i) declare any dividend on 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 amount to which holders of shares of Series A Junior Participating Preferred
Stock were entitled immediately prior to such event under clause (b) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

         (B) The Corporation shall declare a dividend or distribution on the
Series A Junior 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 and be cumulative on outstanding
shares of Series A Junior Participating Preferred Stock from the Quarterly
Dividend Payment Date next preceding the date of issue of such shares of Series
A Junior 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 Junior 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 and be cumulative from such
Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear
interest. Dividends paid on the shares of Series A Junior 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 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 Junior 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 3. Voting Rights. The holders of shares of Series A Junior
Participating Preferred Stock shall have the following voting rights:

         (A) Subject to the provision for adjustment hereinafter set forth, each
share of Series A Junior Participating Preferred Stock shall entitle the holder
thereof to 100 votes on all matters submitted to a vote of the stockholders of
the Corporation. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on 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 number of votes per share to which holders of shares of Series A Junior
Participating Preferred Stock were entitled immediately prior to such


                                       3
<PAGE>   35


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

         (B) Except as otherwise provided herein or by law, the holders of
shares of Series A Junior 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) (i) If at any time dividends on any Series A Junior
     Participating Preferred Stock shall be in arrears in an amount equal to six
     (6) quarterly dividends thereon, the occurrence of such contingency shall
     mark the beginning of a period (herein called a "default period") which
     shall extend until such time when all accrued and unpaid dividends for all
     previous quarterly dividend periods and for the current quarterly dividend
     period on all shares of Series A Junior Participating Preferred Stock then
     outstanding shall have been declared and paid or set apart for payment.
     During each default period, all holders of Preferred Stock (including
     holders of the Series A Junior Participating Preferred Stock) with
     dividends in arrears in an amount equal to six (6) quarterly dividends
     thereon, voting as a class, irrespective of series, shall have the right to
     elect two (2) directors.

                 (ii) During any default period, such voting right of the
     holders of Series A Junior Participating Preferred Stock may be exercised
     initially at a special meeting called pursuant to subparagraph (iii) of
     this Section 3(C) or at any annual meeting of stockholders, and thereafter
     at annual meetings of stockholders, provided that neither such voting right
     nor the right of the holders of any other series of Preferred Stock, if
     any, to increase, in certain cases, the authorized number of directors
     shall be exercised unless the holders of ten percent (10%) in number of
     shares of Preferred Stock outstanding shall be present in person or by
     proxy. The absence of a quorum of the holders of Common Stock shall not
     affect the exercise








                                       4
<PAGE>   36



     by the holders of Preferred Stock of such voting right. At any meeting at
     which the holders of Preferred Stock shall exercise such voting right
     initially during an existing default period, they shall have the right,
     voting as a class, to elect directors to fill such vacancies, if any, in
     the Board of Directors as may then exist up to two (2) directors or, if
     such right is exercised at an annual meeting, to elect two (2) directors.
     If the number which may be so elected at any special meeting does not
     amount to the required number, the holders of the Preferred Stock shall
     have the right to make such increase in the number of directors as shall be
     necessary to permit the election by them of the required number. After the
     holders of the Preferred Stock shall have exercised their right to elect
     directors in any default period and during the continuance of such period,
     the number of directors shall not be increased or decreased except by vote
     of the holders of Preferred Stock as herein provided or pursuant to the
     rights of any equity securities ranking senior to or pari passu with the
     Series A Junior Participating Preferred Stock.

                 (iii) Unless the holders of Preferred Stock shall, during an
     existing default period, have previously exercised their right to elect
     directors, the Board of Directors may order, or any stockholder or
     stockholders owning in the aggregate not less than ten percent (10%) of the
     total number of shares of Preferred Stock outstanding, irrespective of
     series, may request, the calling of a special meeting of the holders of
     Preferred Stock, which meeting shall thereupon be called by the President,
     a Vice-President or the Secretary of the Corporation. Notice of such
     meeting and of any annual meeting at which holders of Preferred Stock are
     entitled to vote pursuant to this Paragraph (C)(iii) shall be given to each
     holder of record of Preferred Stock by mailing a copy of such notice to him
     at his last address as the same appears on the books of the Corporation.
     Such meeting shall be called for a time not earlier than 20 days and not
     later than 60 days after such order or request or in







                                       5
<PAGE>   37


     default of the calling of such meeting within 60 days after such order or
     request, such meeting may be called on similar notice by any stockholder or
     stockholders owning in the aggregate not less than ten percent (10%) of the
     total number of shares of Preferred Stock outstanding. Notwithstanding the
     provisions of this Paragraph (C)(iii), no such special meeting shall be
     called during the period within 60 days immediately preceding the date
     fixed for the next annual meeting of the stockholders.

                 (iv) In any default period, the holders of Common Stock, and
     other classes of stock of the Corporation if applicable, shall continue to
     be entitled to elect the whole number of directors until the holders of
     Preferred Stock shall have exercised their right to elect two (2) directors
     voting as a class, after the exercise of which right (x) the directors so
     elected by the holders of Preferred Stock shall continue in office until
     their successors shall have been elected by such holders or until the
     expiration of the default period, and (y) any vacancy in the Board of
     Directors may (except as provided in Paragraph (C)(ii) of this Section 3)
     be filled by vote of a majority of the remaining directors theretofore
     elected by the holders of the class of stock which elected the director
     whose office shall have become vacant. References in this Paragraph (C) to
     directors elected by the holders of a particular class of stock shall
     include directors elected by such directors to fill vacancies as provided
     in clause (y) of the foregoing sentence.

                 (v) Immediately upon the expiration of a default period, (x)
     the right of the holders of Preferred Stock as a class to elect directors
     shall cease, (y) the term of any directors elected by the holders of
     Preferred Stock as a class shall terminate, and (z) the number of directors
     shall be such number as may be provided for in the amended and restated
     certificate of incorporation or by-laws irrespective of any increase made
     pursuant to the provisions of Paragraph (C)(ii) of this Section







                                       6
<PAGE>   38


     3 (such number being subject, however, to change thereafter in any manner
     provided by law or in the amended and restated certificate of incorporation
     or by-laws). Any vacancies in the Board of Directors effected by the
     provisions of clauses (y) and (z) in the preceding sentence may be filled
     by a majority of the remaining directors.

         (D) Except as set forth herein, holders of Series A Junior
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 4. Certain Restrictions.

         (A) Whenever quarterly dividends or other dividends or distributions
payable on the Series A Junior Participating Preferred Stock as provided in
Section 2 are in arrears, thereafter and until all accrued and unpaid dividends
and distributions, whether or not declared, on shares of Series A Junior
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 Junior 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 the Series A
     Junior Participating Preferred Stock, except dividends paid ratably on the
     Series A Junior 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;



                                       7
<PAGE>   39



                 (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 Junior
     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 Junior Participating Preferred Stock; or

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

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

         Section 5. Reacquired Shares. Any shares of Series A Junior
Participating Preferred Stock purchased or otherwise acquired by the Corporation
in any manner whatsoever shall be retired and cancelled 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.



                                       8
<PAGE>   40



         Section 6. Liquidation, Dissolution or Winding Up. (A) Upon any
liquidation (voluntary or otherwise), dissolution or winding up of the
Corporation, no distribution shall be made to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Junior Participating Preferred Stock unless, prior
thereto, the holders of shares of Series A Junior Participating Preferred Stock
shall have received an amount equal to $100 per share of Series A Participating
Preferred Stock, plus an amount equal to accrued and unpaid dividends and
distributions thereon, whether or not declared, to the date of such payment (the
"Series A Liquidation Preference"). Following the payment of the full amount of
the Series A Liquidation Preference, no additional distributions shall be made
to the holders of shares of Series A Junior Participating Preferred Stock
unless, prior thereto, the holders of shares of Common Stock shall have received
an amount per share (the "Common Adjustment") equal to the quotient obtained by
dividing (i) the Series A Liquidation Preference by (ii) 100 (as appropriately
adjusted as set forth in subparagraph (C) below to reflect such events as stock
splits, stock dividends and recapitalizations with respect to the Common Stock)
(such number in clause (ii), the "Adjustment Number"). Following the payment of
the full amount of the Series A Liquidation Preference and the Common Adjustment
in respect of all outstanding shares of Series A Junior Participating Preferred
Stock and Common Stock, respectively, holders of Series A Junior Participating
Preferred Stock and holders of shares of Common Stock shall receive their
ratable and proportionate share of the remaining assets to be distributed in the
ratio of the Adjustment Number to 1 with respect to such Preferred Stock and
Common Stock, on a per share basis, respectively.

         (B) In the event, however, that there are not sufficient assets
available to permit payment in full of the Series A Liquidation Preference and
the liquidation preferences of all other series of preferred stock, if any,
which rank on a parity with the Series A Junior Participating Preferred Stock,
then such remaining assets shall be distributed ratably to the holders of such
parity shares in proportion to their respective liquidation preferences. In the
event, however, that there are not sufficient assets available to permit payment
in full of the Common Adjustment, then such remaining assets shall be
distributed ratably to the holders of Common Stock.


                                       9
<PAGE>   41



         (C) In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on 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 Adjustment Number in effect immediately prior to such event shall be
adjusted by multiplying such Adjustment Number by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

         Section 7. 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 Junior Participating Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share (subject to the provision
for adjustment hereinafter set forth) equal to 100 times the aggregate amount of
stock, securities, cash and/or any other property (payable in kind), as the case
may be, into which or for which each share of Common Stock is changed or
exchanged. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on 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 amount set forth in the preceding sentence with respect to the exchange or
change of shares of Series A Junior Participating Preferred Stock shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

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



                                       10
<PAGE>   42


         Section 9. Ranking. The Series A Junior 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 10. Amendment. At any time when any shares of Series A Junior
Participating Preferred Stock are outstanding, neither the Amended and Restated
Certificate of Incorporation of the Corporation nor this Certificate of
Designation shall be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series A Junior
Participating Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of [a majority] or more of the outstanding
shares of Series A Junior Participating Preferred Stock, voting separately as a
class.

         Section 11. Fractional Shares. Series A Junior 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 Junior Participating Preferred Stock.

         IN WITNESS WHEREOF, we have executed and subscribed this Certificate
and do affirm the foregoing as true under the penalties of perjury this 30th day
of September, 1999.

             6.75% REDEEMABLE CUMULATIVE CONVERTIBLE PREFERRED STOCK
         SETTING FORTH THE POWERS, PREFERENCES, RIGHTS, QUALIFICATIONS,
              LIMITATIONS AND RESTRICTIONS OF SUCH PREFERRED STOCK

         Pursuant to Section 151 of the Delaware General Corporation Law,
Williams Communications Group, Inc., a Delaware corporation (the "Company"),
does hereby certify that the Board of Directors of the Company (the "Board of
Directors") and the Special Committee of the Board of Directors (the "Special
Committee"), pursuant to and in accordance with authority validly delegated to
the Special Committee by resolutions duly adopted by the Board of Directors,
duly adopted the following resolution and that such resolution has not been
modified and is in full force and effect:

         RESOLVED that, pursuant to the authority vested in the Board of
Directors (including as delegated to the Special Committee) in accordance with
the provisions of the Restated Certificate of Incorporation of the Company (the
"Certificate of Incorporation"), a series of preferred stock of the Company is
hereby created and the designation and number of shares thereof and the voting
powers, preferences and relative, participating, optional and other special
rights of the shares of such series, and the qualifications, limitations and
restrictions thereof, are as set forth below in this Certificate of Designations
(this "Certificate"):

         SECTION 1. NUMBER; DESIGNATION; REGISTERED FORM. (a) The shares of such
series shall be designated as "6.75% Redeemable Cumulative Convertible Preferred
Stock" (the "Preferred Stock") and shall have a par value of $.01 per share. The
number of shares constituting the Preferred Stock shall initially be 5,750,000.
Certificates for shares of Preferred Stock shall be issuable only in registered
form.

                  (b) All shares of Preferred Stock redeemed, purchased,
exchanged, converted or otherwise acquired by the Company shall be retired and
canceled and, upon the taking of any action required by applicable law, shall be
restored to the status of authorized but unissued shares of Preferred Stock of
the Company, without designation as to series, and may thereafter be reissued.

                  (c) Capitalized terms used herein and not otherwise defined
shall have the respective meanings set forth in Section 11 below.

         SECTION 2. RANKING. The Preferred Stock shall, with respect to dividend
rights and rights upon liquidation, winding-up or dissolution, rank:

                  (a) senior to the Common Stock, the Class B Common Stock and
any other class or series of Capital Stock of the Company, the terms of which do
not expressly provide that such class or series ranks senior to or on a parity
with the Preferred Stock as to dividend rights and rights on liquidation,
winding-up and dissolution of the Company (collectively, the "Junior Stock");

                  (b) on a parity with any other class or series of Capital
Stock of the Company, the terms of which expressly provide that such class or
series ranks on a parity with the Preferred Stock as to dividend rights and
rights on liquidation, winding-up and dissolution of the Company (collectively,
the "Parity Stock"); and

                  (c) junior to each class or series of Capital Stock of the
Company, the terms of which expressly provide that such class or series ranks
senior to the Preferred Stock as to dividend rights and rights on liquidation,
winding-up and dissolution of the Company (collectively, the "Senior Stock").



<PAGE>   44


         SECTION 3. DIVIDENDS. (a) The holders of shares of Preferred Stock
shall be entitled to receive, when, as and if declared by the Board of Directors
out of funds legally available therefor, dividends on the shares of Preferred
Stock, cumulative from the first date of issuance of any such shares (the
"Initial Issuance Date"), at a rate per annum equal to 6.75% of the Liquidation
Preference per share, payable in cash. Dividends on the shares of Preferred
Stock shall be payable quarterly in arrears on January 15, April 15, July 15 and
October 15 of each year, or if any such date is not a Business Day, on the next
succeeding Business Day (each such date, a "Dividend Payment Date", and each
such quarterly period, a "Dividend Period"), beginning on January 15, 2001, in
preference to and in priority over dividends on any Junior Stock but subject to
the rights of any holders of Senior Stock or Parity Stock. Such dividends shall
be paid to the holders of record of the shares of Preferred Stock as they appear
on the applicable Record Date. As used herein, the term "Record Date" means,
with respect to the dividends payable on January 15, April 15, July 15 and
October 15 of each year, January 1, April 1, July 1 and October 1 of each year,
respectively, or such other record date, not more than 60 days and not less than
10 days preceding the applicable Dividend Payment Date, as shall be fixed by the
Board of Directors. Dividends on the shares of Preferred Stock shall be fully
cumulative and shall accumulate (whether or not there are funds of the Company
legally available for the payment of dividends) from the Initial Issuance Date
(or the last Dividend Payment Date for which dividends were paid, whichever is
later) based on a 360-day year comprised of twelve 30-day months. Arrearages of
unpaid dividends for any past Dividend Period and dividends in connection with
any optional redemption may be declared and paid at any time, without reference
to any Dividend Payment Date, to holders of record on such date, not more than
45 days prior to the payment thereof, as may be fixed by the Board of Directors.

                  (b) No dividend whatsoever shall be declared or paid upon, or
any sum set apart for the payment of dividends upon, any outstanding share of
Preferred Stock with respect to any dividend period unless all dividends for all
preceding dividend periods have been declared and paid, or declared and a
sufficient sum set apart for the payment of such dividends, upon all outstanding
shares of Preferred Stock.

                  (c) No dividend shall be declared or paid or set apart for
payment or other distribution declared or made, whether in cash, obligations or
shares of Capital Stock of the Company or other property, directly or
indirectly, upon any shares of Junior Stock or Parity Stock, nor shall any
shares of Junior Stock or Parity Stock be redeemed, repurchased or otherwise
acquired for consideration by the Company through a sinking fund or otherwise,
unless all accumulated and unpaid dividends, including Special Dividends, if
any, through the most recent Dividend Payment Date (whether or not there are
funds of the Company legally available for the payment of dividends) on the
shares of Preferred Stock and any Parity Stock have been or contemporaneously
are declared and paid in full or set apart for payment; provided, however, that,
notwithstanding any provisions of this paragraph (c) to the contrary, the
Company shall be entitled to (i) declare and pay dividends on shares of Junior
Stock payable solely in shares of Junior Stock and on shares of Parity Stock
payable solely in shares of Parity Stock or Junior Stock, or in each case, by an
increase in the liquidation preference of the Junior Stock or Parity Stock, and
(ii) redeem, repurchase or otherwise acquire Junior Stock or Parity Stock in
exchange for consideration consisting of Junior Stock, in the case of Junior
Stock, or Parity Stock or Junior Stock, in the case of Parity Stock. When
dividends are not paid in full, as aforesaid, upon the shares of Preferred
Stock, all dividends declared on the Preferred Stock and any other Parity Stock
shall be declared and paid either (A) pro rata so that the amount of dividends
so declared on the shares of Preferred Stock and each such other class or series
of Parity Stock shall in all cases bear to each other the same ratio as
accumulated dividends on the shares of Preferred Stock and such class or series
of Parity Stock bear to each other or (B) on another basis that is at least as
favorable to the holders of the Preferred Stock entitled to receive such
dividends.

                  (d) All dividends paid with respect to shares of Preferred
Stock pursuant to this Section 3 shall be paid pro rata to the holders entitled
thereto. Holders of the Preferred Stock will not be entitled to any dividends,
whether payable in cash, property or stock, in excess of the full cumulative
dividends as herein described. In the event that the equivalent of six quarterly
dividends payable on the shares of Preferred Stock are accumulated and unpaid
(whether or not consecutive and whether or not declared), the holders will have
the rights and remedies set forth in Section 6(c).

                  (e) The Company shall have the option to pay all or any part
of a dividend by delivering shares of Common Stock to the transfer agent for the
Preferred Stock (the "Transfer Agent") to be resold for cash. In such case, the
Company shall be obligated to deliver to the Transfer Agent a number of shares
of Common Stock which, when resold by the Transfer Agent, shall result in net
cash proceeds sufficient to pay the applicable dividend in cash to the holders
of shares of Preferred Stock. All shares of Common Stock that the Company may
deliver to the Transfer Agent as provided in this paragraph (e) shall be
registered under the Securities Act of 1933, as amended (the "Securities Act").

                  (f) (i) Upon the occurrence of a Registration Default,
         additional dividends ("Special Dividends") will accumulate on the
         Preferred Stock, from and including the date of such Registration
         Default to but excluding the day on which such Registration Default has
         been cured. In the event of each such Registration Default, the Company
         shall pay Special Dividends to each holder of Preferred Stock at a rate
         per annum equal to 0.50% of the Liquidation Preference of the Preferred
         Stock, which shall accumulate from the date of the Registration Default
         to and including the 90th day following such Registration Default, and
         shall increase by 0.25% per annum of the Liquidation Preference for
         each subsequent 90-day period; provided, however, that such Special
         Dividends may not accumulate at any time at a rate greater than 1.00%
         per annum of the Liquidation Preference of the Preferred Stock in the
         aggregate regardless of the number of Registration Defaults then in
         effect. Following the cure of all Registration Defaults, the
         accumulation of Special Dividends with respect to such Preferred Stock
         shall cease (without in any way limiting the effect of any subsequent
         Registration Default).

                  (ii) If, after the cure of all Registration Defaults then in
         effect, there is a subsequent Registration Default, the Special
         Dividends for such subsequent Registration Default shall initially be
         0.25% per annum of the Liquidation Preference of the Preferred Stock,
         regardless of the Special Dividends in effect with respect to any prior
         Registration Default at the time of the cure of such Registration
         Default.

                  (iii) The Company shall notify the Transfer Agent within five
         Business Days after each and every date on which a Registration Default
         occurs. Special Dividends shall be paid by the Company to the record
         Holders of shares of Preferred Stock on each Dividend Payment Date in
         the manner provided for payment of regular dividends. Each obligation
         to pay Special Dividends shall be deemed to commence accumulating on
         the date of the applicable Registration Default and to cease
         accumulating when all Registration Defaults have been cured.

         SECTION 4. LIQUIDATION PREFERENCE. Each share of Preferred Stock will
have a preference on liquidation equal to $50.00 per share (the "Liquidation
Preference").

                  (a) Upon any voluntary or involuntary liquidation, dissolution
or winding-up of the Company, each holder of shares of Preferred Stock shall be
entitled to payment out of the assets of the Company available for distribution
of an amount equal to the then effective Liquidation Preference per share of
Preferred Stock held by such holder, plus all accumulated and unpaid dividends,
including Special Dividends, if any, thereon to the date of such liquidation,
dissolution or winding-up, before any distribution is made on any Junior Stock,
including, without limitation, the Common Stock, but after any distributions on
any Senior Stock. After payment in full of the then- effective Liquidation
Preference and all accumulated and unpaid dividends, including Special
Dividends, if any, to which holders of shares of Preferred Stock are entitled,
such holders shall not be entitled to any further participation in any
distribution of assets of the Company. If, upon any voluntary or involuntary
liquidation, dissolution or winding-up of the Company, the amounts payable with
respect to shares of Preferred Stock and all other Parity Stock are not paid in
full, the holders of shares of Preferred Stock and the holders of the Parity
Stock shall share equally and ratably in any distribution of assets of the
Company in proportion to the full Liquidation Preference and all accumulated and
unpaid dividends, including Special Dividends, if any, to which each such holder
is entitled.

<PAGE>   46


                  (b) Neither the voluntary sale, conveyance, exchange or
transfer (for cash, shares of stock, securities or other consideration) of all
or substantially all of the property or assets of the Company nor the
consolidation, merger or amalgamation of the Company with or into any
corporation or the consolidation, merger or amalgamation of any corporation with
or into the Company shall be deemed to be a voluntary or involuntary
liquidation, dissolution or winding-up of the Company.

                  (c) No funds are required to be set aside to protect the
Liquidation Preference of the shares of Preferred Stock, although such
Liquidation Preference will be substantially in excess of the par value of the
shares of the Preferred Stock.

         SECTION 5. REDEMPTION. Shares of Preferred Stock shall be redeemable by
the Company as provided below.

                  (a) Optional Redemption. The shares of Preferred Stock shall
not be redeemable prior to October 15, 2005 (the "Initial Redemption Date").
After the Initial Redemption Date, the shares of Preferred Stock shall be
subject to redemption at any time or from time to time at the option of the
Company, in whole or in part, upon not less than 30 nor more than 60 days prior
notice sent by first class mail to each holder's registered address, at a price,
payable in cash, equal to the percentage set forth below of the Liquidation
Preference per share for redemption during the 12-month period beginning on the
dates indicated below, plus, in each case, an amount equal to accumulated and
unpaid dividends, including Special Dividends, if any, thereon (the "Optional
Redemption Price"), whether or not there are funds of the Company legally
available for the payment of dividends, to the Redemption Date (except to the
extent payable to a holder of Preferred Stock on a dividend payment Record Date
prior to the Redemption Date).

</TABLE>

                  (b) Mandatory Redemption. On October 15, 2012, the Company
shall be obligated to redeem all outstanding shares of Preferred Stock for cash,
upon not less than 30 nor more than 60 days notice sent by first class mail to
each holder's registered address, at a price (the "Mandatory Redemption Price"),
payable in cash, equal to 100.00% of the Liquidation Preference per share, plus
accumulated and unpaid dividends, including Special Dividends, if any, to the
Redemption Date (except to the extent payable to a holder of Preferred Stock on
a dividend payment Record Date prior to the Redemption Date).

                  (c) Redemption Procedures. (i) In the event that fewer than
         all of the shares of Preferred Stock are to be redeemed pursuant to
         this Section 5, the Company shall call for redemption shares of
         Preferred Stock pro rata among the holders, based on the number of
         shares of Preferred Stock held by each holder (with adjustments to
         avoid fractional shares), except that the Company may redeem all of the
         shares of Preferred Stock held by any holders of fewer than 100 shares
         of Preferred Stock (or all the shares of Preferred Stock held by
         holders who would hold less than 100 shares of Preferred Stock as a
         result of such redemption). If fewer than all the shares of Preferred
         Stock represented by any share certificate are to be so redeemed, (i)
         the Company shall issue a new certificate for the shares not redeemed
         and (ii) if any shares represented thereby are converted before
         termination of the conversion right with respect to such shares, such
         converted shares shall be deemed (so far as may be) to be the shares
         represented by such share certificate that was selected for redemption.


                                        4

<PAGE>   47



                           (ii) In the event the Company elects to effect an
         optional redemption, the Company shall (i) make a public announcement
         of the redemption and (ii) give a redemption notice (the "Redemption
         Notice") to the holders not fewer than 30 days nor more than 60 days
         before the Redemption Date. Whenever a Redemption Notice is required to
         be delivered to the holders, such Redemption Notice shall provide the
         information set forth below and be given by first class mail, postage
         prepaid to each holder of shares of Preferred Stock to be redeemed, at
         such holder's address appearing in the Preferred Stock register. All
         Redemption Notices shall identify the Preferred Stock to be redeemed
         (including CUSIP number) and shall state:

                  (A) the Redemption Date;

                  (B) the Redemption Price;

                  (C) if fewer than all outstanding shares of Preferred Stock
         are to be redeemed, the identification (and, in the case of partial
         redemption, the certificate number, the total number of shares
         represented thereby and the number of such shares being redeemed on the
         Redemption Date) of the particular shares of Preferred Stock to be
         redeemed;

                  (D) that, on the Redemption Date, the Redemption Price to the
         Redemption Date, will become due and payable upon each such share of
         Preferred Stock to be redeemed and that dividends thereon will cease to
         accumulate on and after said date;

                  (E) the Conversion Price, the date on which the right to
         convert Preferred Stock to be redeemed will terminate and the place or
         places where such Preferred Stock may be surrendered for conversion;
         and

                  (F) the place of places where such Preferred Stock is to be
         surrendered for payment of the Redemption Price.

                  The Redemption Notice shall be given by the Company or, at the
         Company's request, by the Registrar in the name and at the expense of
         the Company; provided, that if the Company so requests, it shall
         provide the Registrar adequate time, as reasonably determined by the
         Registrar, to deliver such notices in a timely fashion.

                           (iii) Prior to any Redemption Date, the Company shall
         deposit with the Registrar or with a Paying Agent (or, if the Company
         is acting as its own Paying Agent, segregate and hold in trust) an
         amount of consideration sufficient to pay the Redemption Price of all
         shares of Preferred Stock which are to be redeemed on that date other
         than any Preferred Stock called for redemption on that date that have
         been converted into shares of Common Stock prior to the date of such
         deposit. If any shares of Preferred Stock called for redemption are
         converted, any consideration deposited with the Registrar or with any
         Paying Agent or so segregated and held in trust for the redemption of
         such shares of Preferred Stock shall (subject to any right of the
         holder of such Preferred Stock to receive accumulated but unpaid
         dividends, including Special Dividends, if any, thereon as provided in
         Section 7) be paid or delivered to the Company upon Company Order or,
         if then held by the Company, shall be discharged from such trust.

                           (iv) Notice of redemption having been given as
         aforesaid, the Redemption Price of the Preferred Stock so to be
         redeemed shall, on the Redemption Date, become due and payable, and
         from and after such date (unless the Company shall default in the
         payment of the Redemption Price), such shares of Preferred Stock shall
         no longer be outstanding, dividends on such Preferred Stock shall cease
         to accumulate, such shares shall cease to be convertible into Common
         Stock and all rights of the holders thereof as stockholders of the
         Company (except the right to receive the Redemption Price) shall cease.
         Upon surrender of any such share





                                       5
<PAGE>   48

         of Preferred Stock for redemption in accordance with said notice, such
         share of Preferred Stock shall be redeemed by the Company at the
         Redemption Price.

                           (v) Any certificate that represents more than one
         share of Preferred Stock and is to be redeemed only in part shall be
         surrendered at any office or agency of the Company designated for that
         purpose (with, if the Company or the Registrar so requires, due
         endorsement by, or a written instrument of transfer in form
         satisfactory to the Company and the Registrar duly executed by, the
         holder thereof or such holder's attorney duly authorized in writing),
         and the Company shall execute, and the Registrar shall countersign and
         deliver to the holder of such shares of Preferred Stock without service
         charge, a new certificate or certificates, representing any number of
         shares of Preferred Stock, as requested by such holder, in an aggregate
         amount equal to and in exchange for the number of shares not redeemed
         and represented by the certificate so surrendered.

                           (vi) In the event that the Redemption Date occurs
         after a dividend payment Record Date and prior to the related Dividend
         Payment Date, the holders of the shares of Preferred Stock at the close
         of business on such dividend payment Record Date shall be entitled to
         receive the dividend payable on such shares on the corresponding
         Dividend Payment Date.

                           (vii) No optional redemption may be authorized or
         made unless, prior to giving the applicable Redemption Notice, all
         accumulated and unpaid dividends, including Special Dividends, if any,
         for periods ended prior to the date of such Redemption Notice shall
         have been paid in cash.

         SECTION 6. VOTING RIGHTS. (a) The holders of shares of Preferred Stock
shall be entitled to vote with the holders of Common Stock on all matters
submitted for a vote of holders of Common Stock and, on such matters, each
holder of shares of Preferred Stock shall be entitled to a number of votes equal
to that number of shares of Common Stock into which such holder's shares of
Preferred Stock are then convertible.

                  (b) The affirmative vote of the holders of at least a majority
of the outstanding shares of Preferred Stock, voting as a single class with
holders of shares of all other classes and series of preferred stock affected in
the same way, in person or by proxy, at a special or annual meeting called for
that purpose, or by written consent in lieu of meeting, will be required to
amend, alter, repeal or change, whether by merger, consolidation, combination,
reclassification or otherwise, any provisions of the Certificate of
Incorporation, the bylaws of the Company or this Certificate in any manner which
would adversely affect, alter or change the powers, preferences or special
rights of the Preferred Stock and any of those securities affected in the same
way; provided that any such amendment or alteration that changes the dividend
payable on, or the Liquidation Preference of, the Preferred Stock shall require
the affirmative vote, at a meeting of holders of Preferred Stock duly called for
such purpose, or the written consent, of each holder of a share of Preferred
Stock.

                  (c) (i) If, at any time, the equivalent of six quarterly
         dividends payable on the shares of Preferred Stock are accumulated and
         unpaid (whether or not consecutive and whether or not declared), the
         holders of all outstanding shares of Preferred Stock and any Parity
         Stock or Senior Stock having similar voting rights then exercisable,
         voting separately as a single class without regard to series, shall be
         entitled to elect at the next annual meeting of the stockholders of the
         Company two directors (each, a "Preferred Stock Director") to serve
         until all dividends accumulated and unpaid on any such voting shares
         have been paid, or declared and funds set aside to provide for payment
         in full.

                           (ii) The voting rights set forth in the preceding
         sentence will continue until such time as all dividends in arrears on
         the Preferred Stock are paid in full, at which time the term of any
         Preferred Stock Director shall terminate. At any time after voting
         power to elect directors shall have become vested and be continuing in
         the holders of the Preferred Stock pursuant to this Section 6(c), or if
         a vacancy shall exist in the offices of Preferred Stock Directors, the
         Board of Directors may, and upon written request of the holders


                                       6
<PAGE>   49

         of record of at least 25% of the Outstanding Preferred Stock addressed
         to the Chairman of the Board of the Company shall, call a special
         meeting of the holders of the Preferred Stock for the purpose of
         electing the Preferred Stock Directors that such holders are entitled
         to elect. At any meeting held for the purpose of electing Preferred
         Stock Directors, the presence in person or by proxy of the holders of
         at least a majority of the Outstanding Preferred Stock shall be
         required to constitute a quorum of such Preferred Stock. Any vacancy
         occurring in the office of a Preferred Stock Director may be filled by
         the remaining Preferred Stock Director unless and until such vacancy
         shall be filled by the holders of the Preferred Stock. The Preferred
         Stock Directors shall agree, prior to their election to office, to
         resign upon any termination of the right of the holders of Preferred
         Stock to vote as a class for Preferred Stock Directors as herein
         provided, and upon such termination, the Preferred Stock Directors then
         in office shall forthwith resign.

                  (d) The creation, authorization or issuance of any other class
or series of the Company's Capital Stock, any increase or decrease in the amount
of authorized capital stock of any of those classes or series or of the
Preferred Stock (other than a decrease in the amount of authorized Preferred
Stock to an amount that is less than the Outstanding Preferred Stock at the time
of such decrease), or any increase, decrease or change in the par value of any
class or series of Capital Stock, including the Preferred Stock, will not
require the consent of the holders of the Preferred Stock and will not be deemed
to affect adversely, alter or change the powers, preferences and special rights
of the shares of Preferred Stock.

         SECTION 7. CONVERSION. (a) Each share of Preferred Stock shall be
convertible at any time and from time to time at the option of the holder
thereof into fully paid and nonassessable shares of Common Stock. The number of
shares of Common Stock deliverable upon conversion of a share of Preferred
Stock, adjusted as hereinafter provided, is referred to herein as the
"Conversion Ratio". The Conversion Ratio as of the Initial Issuance Date shall
be 1.7610 and shall equal the ratio the numerator of which is the Liquidation
Preference and the denominator of which is the Conversion Price (rounded to the
nearest 1/1000 of a share). The "Conversion Price" shall be $28.39, subject to
adjustment from time to time as provided in Section 8.

                  (b) Conversion of shares of Preferred Stock may be effected by
any holder upon the surrender to the Company, at the principal office of the
Company or at the office of the Transfer Agent as may be designated by the Board
of Directors, of the certificate or certificates for such shares of Preferred
Stock to be converted accompanied by a written notice stating that such holder
elects to convert all or a specified whole number of such shares in accordance
with the provisions of this Section 7 and specifying the name or names in which
such holder wishes the certificate or certificates for shares of Common Stock to
be issued. In case such notice shall specify a name or names other than that of
such holder, such notice shall be accompanied by payment of all transfer taxes
payable upon the issuance of shares of Common Stock in such name or names. Other
than such taxes, the Company shall pay any documentary, stamp or similar issue
or transfer taxes that may be payable in respect of any issuance or delivery of
shares of Common Stock upon conversion of shares of Preferred Stock pursuant
hereto. As promptly as practicable after the surrender of such certificate or
certificates and the receipt of such notice relating to the conversion and
payment of all required transfer taxes, if any (or the demonstration to the
satisfaction of the Company that such taxes have been paid), the Company shall
deliver or cause to be delivered (i) certificates representing the number of
validly issued, fully paid and nonassessable full shares of Common Stock to
which the holder of shares of Preferred Stock being converted (or such holder's
transferee) shall be entitled, and (ii) if less than the full number of shares
of Preferred Stock evidenced by the surrendered certificate or certificates is
being converted, a new certificate or certificates, of like tenor, for the
number of shares evidenced by such surrendered certificate or certificates less
the number of shares being converted. Such conversion shall be deemed to have
been made at the close of business on the date of giving such notice and of such
surrender of the certificate or certificates representing the shares of
Preferred Stock to be converted so that the rights of the holder thereof as to
the shares being converted shall cease except for the right to receive shares of
Common Stock and, to the extent so provided in Section 7(c), accumulated and
unpaid dividends, including Special Dividends, if any, with respect to the
shares of Preferred Stock being converted, in each case, in accordance herewith,
and the person entitled to receive the shares of Common Stock shall be treated
for all purposes as having become the record holder of such shares of Common
Stock at such time.


                                       7
<PAGE>   50


                  (c) Holders of shares of Preferred Stock at the close of
business on a dividend payment Record Date will be entitled to receive the
dividend payable on such shares on the corresponding Dividend Payment Date
notwithstanding the conversion of such shares following the dividend payment
Record Date and prior to such Dividend Payment Date. However, shares of
Preferred Stock surrendered for conversion during the period between the close
of business on any dividend payment Record Date and the opening of business on
the corresponding Dividend Payment Date must be accompanied by payment of an
amount equal to the dividend payable on such shares on such Dividend Payment
Date. Notwithstanding the foregoing, if shares of Preferred Stock are converted
during the period between the close of business on any dividend payment Record
Date and the opening of business on the corresponding Dividend Payment Date, and
we have called such shares of Preferred Stock for redemption or we have given a
notice to the holders of shares of Preferred Stock that we will cause the
conversion rights of such shares to terminate, the holder who tenders such
shares for conversion will receive the dividend payable on such Dividend Payment
Date and need not include payment of the amount of such dividend upon surrender
of shares of Preferred Stock for conversion. A holder of shares of Preferred
Stock on a dividend payment Record Date who converts such shares into shares of
Common Stock on the corresponding Dividend Payment Date will receive the
dividend payable on such shares of Preferred Stock on such Dividend Payment
Date, and the converting holder need not include payment of the amount of such
dividend upon surrender of shares of Preferred Stock for conversion. Except as
provided above, we will make no payment or allowance for unpaid dividends,
whether or not in arrears, on converted shares of Preferred Stock or the
dividends on the shares of Common Stock issued upon such conversion.

                  (d) In case any shares of Preferred Stock are to be redeemed
pursuant to Section 5, such right of conversion shall cease and terminate, as to
the shares of Preferred Stock to be redeemed, at the close of business on the
Business Day immediately preceding the date fixed for redemption, unless the
Company shall default in the payment of the Redemption Price therefor, as
provided herein.

                  (e) In connection with the conversion of any shares of
Preferred Stock, no fractions of shares of Common Stock shall be issued. In lieu
thereof, the Company shall round the applicable number of shares up or down to
the nearest whole number of shares. If more than one share of Preferred Stock
shall be surrendered for conversion by the same holder at the same time, the
number of full shares of Common Stock issuable on conversion thereof shall be
computed on the basis of the total number of shares of Preferred Stock so
surrendered.

                  (f) The Company shall at all times reserve and keep available,
free from preemptive rights, for issuance upon the conversion of shares of
Preferred Stock such number of its authorized but unissued shares of Common
Stock as will from time to time be sufficient if necessary to permit the
conversion of all outstanding shares of Preferred Stock. Prior to the delivery
of any securities which the Company shall be obligated to deliver upon
conversion of the Preferred Stock, the Company shall comply with all applicable
federal and state laws and regulations which require action to be taken by the
Company. All shares of Common Stock delivered upon conversion of the Preferred
Stock will upon delivery be duly and validly issued and fully paid and
nonassessable, free of all liens and charges and not subject to any preemptive
rights.

         SECTION 8. CONVERSION PRICE ADJUSTMENTS. (a) The Conversion Price shall
be subject to adjustment from time to time as follows:

                           (i) STOCK SPLITS AND COMBINATIONS. In case the
         Company shall at any time or from time to time after the Initial
         Issuance Date (A) subdivide or split the outstanding shares of Common
         Stock, (B) combine or reclassify the outstanding shares of Common Stock
         into a smaller number of shares or (C) issue by reclassification of the
         shares of Common Stock any shares of Capital Stock of the Company,
         then, and in each such case, the Conversion Price in effect immediately
         prior to such event or the record date therefor, whichever is earlier,
         shall be adjusted so that the holder of any shares of Preferred Stock
         thereafter surrendered for conversion shall be entitled to receive the
         number of shares of Common Stock or other securities of the Company
         which such holder would have owned or have been entitled to receive
         after the


                                       8
<PAGE>   51

         occurrence of any of the events described above, had such shares of
         Preferred Stock been surrendered for conversion immediately prior to
         the occurrence of such event or the record date therefor, whichever is
         earlier. An adjustment made pursuant to this subparagraph (i) shall
         become effective at the close of business on the day upon which such
         corporate action becomes effective. Such adjustment shall be made
         successively whenever any event listed above shall occur.

                           (ii) STOCK DIVIDENDS IN COMMON STOCK. In case the
         Company shall at any time or from time to time after the Initial
         Issuance Date pay a dividend or make a distribution in shares of Common
         Stock on any class of Capital Stock of the Company other than dividends
         or distributions of shares of Common Stock or other securities with
         respect to which adjustments are provided in Section 8(a)(i) above, and
         the total number of shares constituting such dividend or distribution
         shall exceed 25% of the total number of shares of Common Stock
         outstanding at the close of business on the record date fixed for
         determination of stockholders entitled to receive such dividend or
         distribution, the Conversion Price shall be adjusted so that the holder
         of each share of Preferred Stock shall be entitled to receive upon
         conversion thereof, the number of shares of Common Stock determined by
         multiplying (A) the applicable Conversion Price by (B) a fraction, the
         numerator of which shall be the number of shares of Common Stock
         theretofore outstanding and the denominator of which shall be the sum
         of such number of shares and the total number of shares issued in such
         dividend or distribution. In case the total number of shares
         constituting such dividend or distribution shall not exceed 25% of the
         total number of shares of Common Stock outstanding at the close of
         business on the record date fixed for such dividend or distribution,
         such shares of Common Stock shall be considered to be issued at the
         time of any such next succeeding dividend or other distribution in
         which the number of shares of Common Stock issued, together with the
         number of shares issued in all previous such dividends and
         distributions for which no adjustment to the Conversion Price has been
         made, exceeds 25% of the total number of shares of Common Stock
         outstanding at the close of business on the record date for such
         dividend or distribution.

                           (iii) ISSUANCE OF RIGHTS OR WARRANTS. In case the
         Company shall issue to all holders of Common Stock rights or warrants
         expiring within 45 days entitling such holders to subscribe for or
         purchase Common Stock at a price per share less than the Current Market
         Price, the Conversion Price in effect immediately prior to the close of
         business on the record date fixed for determination of stockholders
         entitled to receive such rights or warrants shall be reduced by
         multiplying such Conversion Price by a fraction, the numerator of which
         is the sum of the number of shares of Common Stock outstanding at the
         close of business on such record date and the number of shares of
         Common Stock that the aggregate offering price of the total number of
         shares of Common Stock so offered for subscription or purchase would
         purchase at such Current Market Price and the denominator of which is
         the sum of the number of shares of Common Stock outstanding at the
         close of business on such record date and the number of additional
         shares of Common Stock so offered for subscription or purchase. For
         purposes of this subparagraph (iii), the issuance of rights or warrants
         to subscribe for or purchase securities convertible into Common Stock
         shall be deemed to be the issuance of rights or warrants to purchase
         the Common Stock into which such securities are convertible at an
         aggregate offering price equal to the sum of the aggregate offering
         price of such securities and the minimum aggregate amount (if any)
         payable upon conversion of such securities into Common Stock. Such
         adjustment shall be made successively whenever any such event shall
         occur.

                           (iv) DISTRIBUTION OF INDEBTEDNESS, SECURITIES OR
         ASSETS. In case the Company shall distribute to all holders of Common
         Stock (whether by dividend or in a merger, amalgamation or
         consolidation or otherwise) evidences of indebtedness, shares of
         Capital Stock of any class or series, other securities, cash or assets
         (other than Common Stock, rights or warrants referred to in
         subparagraph (iii) above or a dividend payable exclusively in cash and
         other than as a result of a Fundamental Change (as defined below)), the
         Conversion Price in effect immediately prior to the close of business
         on the record date fixed for determination of stockholders entitled to
         receive such distribution shall be reduced by multiplying such
         Conversion Price by a fraction, the numerator of which is the Current
         Market Price on such record date less


                                       9
<PAGE>   52

         the fair market value (as determined by the Board of Directors, except
         in the case of a Spin-Off (as defined below), whose determination in
         good faith shall be conclusive) of the portion of such evidences of
         indebtedness, shares of capital stock, other securities, cash and
         assets so distributed applicable to one share of Common Stock, and the
         denominator of which is the Current Market Price. Such adjustment shall
         be made successively whenever any such event shall occur.

                           In respect of a dividend or other distribution of
         shares of Capital Stock of any class or series, or similar equity
         interests, of or relating to a Subsidiary or other business unit of the
         Company (a "Spin-Off"), the adjustment to the Conversion Price under
         this subparagraph (iv) shall occur at the earlier of (A) 20 trading
         days after the effective date of the Spin-Off and (B) the date of the
         Initial Public Offering of the securities being distributed in the
         Spin-Off, if that Initial Public Offering is effected simultaneously
         with the Spin-Off.

                           (v) FUNDAMENTAL CHANGES. In case any transaction or
         event (including, without limitation, any merger, consolidation,
         combination, recapitalization, sale of assets, tender or exchange
         offer, reclassification, compulsory share exchange or liquidation)
         shall occur in which all or substantially all outstanding shares of
         Common Stock are converted into or exchanged or acquired for or
         constitute the right to receive stock, other securities, cash, property
         or assets (each, a "Fundamental Change"), the holder of each share of
         Preferred Stock outstanding immediately prior to the occurrence of such
         Fundamental Change shall have the right upon any subsequent conversion
         to receive (but only out of legally available funds, to the extent
         required by applicable law) the kind and amount of stock, other
         securities, cash, property or assets that such holder would have
         received if such share had been converted immediately prior thereto.

                           (vi) SPECIAL ADJUSTMENT FOR SOME CHANGES OF CONTROL.
         In the event of a Fundamental Change that constitutes a Change of
         Control in which (A) the stockholders of the Company receive
         consideration per share of Common Stock that is greater than the
         Conversion Price at the effective time of the Change of Control,
         without giving effect to the adjustment described below, and (B) at
         least 10% of the total consideration paid to the stockholders of the
         Company consists of cash, cash equivalents, securities or other assets
         (other than publicly traded securities) (collectively, "Non-Public
         Consideration"), then upon conversion of shares of Preferred Stock
         after the Change of Control, in addition to the Common Stock or other
         securities deliverable upon the conversion of the Preferred Stock as
         described in Section 7 and subparagraphs (i) through (v) above, the
         holder will receive a number of publicly traded securities of the
         acquiror determined through the following calculation:

         PV Cash Flows x (Non-Public Consideration/Total Consideration)
         --------------------------------------------------------------
                              Acquiror Stock Price

                  where:

                  PV Cash Flows  =          the present value of the aggregate
                                            dividend payments that would have
                                            been payable on the Preferred Stock
                                            from the date of conversion through
                                            October 15, 2005. The present value
                                            for this purpose will be calculated
                                            using a discount rate equal to 3.25%
                                            plus the yield to maturity of U.S.
                                            Treasury securities having a
                                            maturity closest to, but not later
                                            than, October 15, 2005;

                  Total
                  Consideration  =          the total value of the consideration
                                            payable to the Company's
                                            stockholders at the effective time
                                            of such Change of Control, with the
                                            value of any assets or securities
                                            other than cash or publicly traded
                                            securities being determined in good
                                            faith by the Board of Directors
                                            based on an opinion as to such value
                                            obtained from an accounting,
                                            appraisal or investment banking firm
                                            of international standing; and


                                       10
<PAGE>   53


                  Acquiror
                  Stock Price    =          the price per security of the
                                            acquiror's publicly traded
                                            securities delivered in connection
                                            with such Change of Control at the
                                            effective time of such Change of
                                            Control;

provided, however, that if the consideration received by the Company's
stockholders in respect of such Change of Control consists of at least 75%
Non-Public Consideration or if the acquiror's common stock is not publicly
traded, then upon conversion of shares of Preferred Stock after such Change of
Control, in lieu of issuing additional securities of the acquiror, as set forth
in this subparagraph (vi), each holder shall be entitled to receive an
additional amount in cash calculated as follows:

         PV Cash Flows x (Non-Public Consideration/Total Consideration)

                  (b) Anything in paragraph (a) to the contrary notwithstanding,
the Company shall not be required to give effect to any adjustment in the
Conversion Price unless and until the net effect of one or more adjustments
(each of which shall be carried forward until counted toward adjustment),
determined as above provided, shall have resulted in a change of the Conversion
Price by at least 1%, and when the cumulative net effect of more than one
adjustment so determined shall be to change the Conversion Price by at least 1%,
such change in the Conversion Price shall thereupon be given effect. In the
event that, at any time as a result of the provisions of this paragraph (b), the
holder of shares of Preferred Stock upon subsequent conversion shall become
entitled to receive any shares of Capital Stock of the Company other than Common
Stock, the number of such other shares so receivable upon conversion of shares
of Preferred Stock shall thereafter be subject to adjustment from time to time
in a manner and on terms as nearly equivalent as practicable to the provisions
contained herein.

                  (c) There shall be no adjustment of the Conversion Price in
case of the issuance of any Capital Stock of the Company in a merger,
reorganization, acquisition, reclassification, recapitalization or other similar
transaction except as provided in this Section.

                  (d) In any case in which paragraph (a) requires that an
adjustment as a result of any event is to become effective from and after a
record date, the Company may elect to defer until after the occurrence of such
event (i) issuing to the holder of any shares of Preferred Stock converted after
such record date and before the occurrence of such event the additional shares
of Common Stock issuable upon such conversion over and above the shares issuable
on the basis of the Conversion Price in effect immediately prior to adjustment
and (ii) paying to such holder any amount in cash in lieu of a fractional share
of Common Stock.

                  (e) If the Company shall take a record of the holders of its
Common Stock for the purpose of entitling them to receive a dividend or other
distribution, and shall thereafter and before the distribution to stockholders
thereof legally abandon its plan to pay or deliver such dividend or
distribution, then thereafter no adjustment in the number of shares of Common
Stock issuable upon exercise of the right of conversion or in the Conversion
Price then in effect shall be required by reason of the taking of such record.

                  (f) The Board of Directors shall have the power to resolve any
ambiguity or correct any error in this Section 8, and its action in so doing
shall be final and conclusive.

         SECTION 9. TERMINATION OF CONVERSION RIGHTS. On or after October 15,
2005, the Company may, at its option, upon not less than 30 nor more than 60
days prior notice sent by first class mail to each holder's registered address,
cause the conversion rights of the shares of Preferred Stock set forth in
Section 7 to terminate. The Company may exercise such option only if, for at
least 20 trading days within any period of 30 consecutive trading days,
including the last trading day of such period, the daily closing price of the
Company's Common Stock exceeds 140% of the Conversion Price, subject to
adjustment as provided in Section 8.


                                       11
<PAGE>   54

         SECTION 10. CHANGE IN CONTROL. (a) If a Change of Control occurs with
respect to the Company, each holder of shares of Preferred Stock shall have the
right to require the Company to purchase all or any part of such holder's shares
of Preferred Stock at a purchase price equal to 100% of the Liquidation
Preference of such shares, plus all accumulated and unpaid dividends, including
Special Dividends, if any, on such shares to the date of purchase. Within 30
days following such Change of Control, the Company shall mail a notice to each
holder of shares of Preferred Stock describing the transaction or transactions
that constitute such Change of Control and offering to purchase such holder's
shares of Preferred Stock on the date specified in such notice, which date shall
be no earlier than 30 days and no later than 60 days from the date such notice
is mailed. The Company shall have the option to pay for such shares either
solely in cash or solely in shares of Common Stock valued at 95% of the average
closing sale price of the Common Stock for the five trading days before and
including the third trading day before the repurchase date.

                  (b) Holders of the Preferred Stock shall not have the right
set forth in paragraph (a) above if:

                           (i) the daily closing price per share of the Common
         Stock for any five trading days within the period of 10 consecutive
         trading days ending immediately after the later of the Change of
         Control or the public announcement thereof (in the case of a Change of
         Control under paragraph (a) of the definition of "Change of Control")
         or the period of 10 consecutive trading days ending immediately before
         the Change of Control (in the case of a Change of Control under
         paragraph (b), (c) or (d) of the definition of "Change of Control")
         shall equal or exceed 105% of the Conversion Price of the Preferred
         Stock in effect on the date of the Change of Control or the public
         announcement thereof, as applicable; or

                           (ii) at least 90% of the consideration in the Change
         of Control transaction consists of Capital Stock traded on a U.S.
         national securities exchange or quoted on the NASDAQ National Market,
         and as a result of the transaction, the Preferred Stock becomes
         convertible solely into such Capital Stock.

                  (c) The Company shall comply with the requirements of Rule
14e-1 under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and any other securities laws and regulations to the extent such laws and
regulations are applicable in connection with the purchase of Preferred Stock as
a result of a Change of Control with respect to the Company. To the extent that
the provisions of any securities laws or regulations conflict with any of the
provisions of this Section 10, the Company shall comply with the applicable
securities laws and regulations and shall be deemed not to have breached its
obligations under this Section 10.

                  (d) On the date scheduled for payment of shares of Preferred
Stock tendered to the Company for repurchase as provided in this Section 10, the
Company shall, to the extent lawful, (i) accept for payment all shares of
Preferred Stock properly tendered, (ii) deposit with the Transfer Agent an
amount equal to the purchase price of the shares of Preferred Stock so tendered
and (iii) deliver or cause to be delivered to the Transfer Agent shares of
Preferred Stock so accepted together with an officers' certificate stating the
aggregate Liquidation Preference of the shares of Preferred Stock being
purchased by the Company. The Transfer Agent shall promptly mail or deliver to
each holder of shares of Preferred Stock so tendered the applicable payment for
such shares of Preferred Stock, and the Transfer Agent shall promptly
countersign and mail or deliver, or cause to be transferred by book-entry, to
each holder new shares of Preferred Stock equal in Liquidation Preference to any
unpurchased portion of the shares of Preferred Stock surrendered, if any. The
Company shall publicly announce the results of its offer on or as soon as
practicable after the payment date for the purchase of shares of Preferred Stock
in connection with a Change of Control of the Company.

                  (e) The Company shall not be required to make an offer to
purchase any shares of Preferred Stock upon the occurrence of a Change of
Control of the Company if a third party makes an offer in the manner, at the
times and otherwise in compliance with the requirements described in this
Section 10 and purchases all shares of Preferred Stock validly tendered and not
withdrawn.

                  (f) The right of the holders of shares of Preferred Stock
described in this Section 10 will be subject to the Company's obligation to:


                                       12

<PAGE>   55



                           (i) repay all obligations in full under the Company's
         credit facility; and

                           (ii) offer to purchase and purchase all of the
         Company's senior redeemable notes that have been tendered for purchase
         in connection with a Change of Control that constitutes a "change of
         control" under the terms of such senior redeemable notes or the
         indenture relating thereto.

                  (g) In addition, the right of the holders of shares of
Preferred Stock described in this Section 10 shall be subject to the repurchase
or repayment of any future indebtedness of the Company that the Company is
required to repurchase or repay in connection with a transaction or event that
constitutes a Change of Control.

         When the Company shall have satisfied the obligations, or repurchased
or repaid the indebtedness, described above in paragraphs (f) and (g) of this
Section 10, and, subject to the legal availability of funds for such purpose,
the Company shall purchase all shares of Preferred Stock tendered for purchase
by the Company upon a Change of Control pursuant to this Section 10.

         SECTION 11. CERTAIN DEFINITIONS. As used in this Certificate, the
following terms shall have the following meanings, unless the context otherwise
requires:

         "Business Day" means any day other than a Saturday, Sunday or a U.S.
federal holiday.

         "Capital Stock" of any person means any and all shares, interests,
participations or other equivalents however designated of corporate stock or
other equity participations, including partnership interests, whether general or
limited, of such person and any rights (other than debt securities convertible
or exchangeable into an equity interest), warrants or options to acquire an
equity interest in such person.

         "Change of Control" means, with respect to the Company, the occurrence
of any of the following:

                  (a)      if any "person" or "group" (as such terms are used in
                           Section 13(d) and Section 14(d) of the Exchange Act
                           or any successor provisions to either of the
                           foregoing), including any group acting for the
                           purpose of acquiring, holding, voting or disposing of
                           securities within the meaning of Rule 13d-5(b)(1)
                           under the Exchange Act, other than any one or more of
                           the Permitted Holders, becomes the "beneficial owner"

         of shares being exchanged and to credit or cause to be credited to the

Preferred Stock bearing the Global Restricted Shares Legend, or if a request is
made to remove such Global Restricted Shares Legend on Preferred Stock, the
Preferred Stock so issued shall bear the Global Restricted Shares Legend and the
Global Restricted Shares Legend shall not be removed unless there is delivered
to the Company and the Registrar such satisfactory evidence, which may include
an opinion of counsel licensed to practice law in the State of New York, as may
be reasonably required by the Company or the Registrar, that neither the legend
nor the restrictions on transfer set forth therein are required to ensure that
transfers thereof comply with the provisions of Rule 144A or Rule 144 or that
such shares of Preferred Stock are not "restricted securities" within the
meaning of Rule 144 under the Securities Act. Upon provision of such
satisfactory evidence, the Registrar, at the direction of the Company, shall
countersign and deliver shares of Preferred Stock that do not bear the Global
Restricted Shares Legend.

                  (d) The Registrar shall have no responsibility for any actions
taken or not taken by the Depositary.

                  (e) The Company agrees that it will refuse to register any
transfer of Preferred Stock or any Common Stock issuable upon conversion thereof
that is not made in accordance with the provisions of Rule 144A, pursuant to a
registration statement that has been declared effective under the Securities Act
or pursuant to an available exemption from the registration requirements of the
Securities Act; provided that the provisions of this paragraph (e) shall not be
applicable to any Preferred Stock that does not bear any Global Restricted
Shares Legend or to any Common Stock that does not bear the Common Share Legend
(as defined below).

Stock prior to the effectiveness of a Shelf Registration Statement shall be
delivered in certificated form and shall bear the common share legend (the

Stock issued prior to the effectiveness of a Shelf Registration Statement are to
be registered in a name other than that of the holder of Preferred Stock or (ii)
shares of Common Stock represented by a certificate bearing the Common Share
Legend are transferred subsequently by such holder, then, unless the Shelf
Registration Statement has become effective and such shares are being
transferred pursuant to the Shelf Registration Statement, the holder must
deliver to the Registrar a certificate in substantially the form of Exhibit D as
to compliance with the restrictions on transfer applicable to such Common Stock
and the Registrar shall not be required to register any transfer of such Common
Stock not so accompanied by a properly completed certificate. Such Common Share
Legend may be removed, and new certificates representing the Common Stock may be
issued, upon the presentation of satisfactory evidence that such Common Share
Legend is no longer required as described above in paragraph (c) of this Section
14 with respect to the Preferred Stock.
