Board of Directors is hereby authorized to issue the shares of Preferred Stock
in such series and to fix from time to time before issuance the number of
shares to be included in any series and the designation, relative powers,
preferences and rights and qualifications, limitations or restrictions of all
shares of such series.  The authority of the Board of Directors with respect to
each series shall include, without limiting the generality of the foregoing,
the determination of any or all of the following:

                 1.  the number of shares of any series and the designation to
         distinguish the shares of such series from the shares of all other
         series;

                 2.  the voting powers, if any, and whether such voting powers
                     are full or limited, in such series;

                 3.  the redemption provisions, if any, applicable to such
         series, including the redemption price or prices to be paid;

                 4.  whether dividends, if any, shall be cumulative or
         noncumulative, the dividend rate of such series, and the dates and
         preferences of dividends on such series;

                 5.  the rights of such series upon the voluntary or
         involuntary dissolution of, or upon any distribution of the assets of,
         the Corporation;

                 6.  the provisions, if any, pursuant to which the shares of
         such series are convertible into, or exchangeable for, shares of any
         other class or classes or of any other series of the same or any other
         class or classes of stock, or any other security, of the Corporation
         or any other corporation, and price or prices or the rates of exchange
         applicable thereto;

                 7.  the right, if any, to subscribe for or to purchase any
         securities of the Corporation or any other corporation;

                 8.  the provisions, if any, of a sinking fund applicable to

         restrictions thereof;

all as shall be determined from time to time by the Board of Directors and
shall be stated in a resolution or resolutions providing for the issuance of

              B.     Common Stock and Class B Common Stock:

                 1.  Subject to Preferred Stock.  The Common Stock and Class B
Common Stock shall be subject to the express terms of the Preferred Stock and
any series thereof.

                 2.  Identical Rights of Common Stock and Class B Common Stock.
Except as otherwise expressly provided in this Restated Certificate of
Incorporation, all shares of Common Stock and Class B Common Stock shall be
identical and shall entitle the holders thereof to the same rights and
privileges.

                 3.  Dividends.  When and as dividends are declared, whether
payable in cash, in property or in securities of the Corporation, the holders
of the Common Stock and Class B Common Stock shall be entitled to share
equally, share for share, in such dividends.  However, if dividends are
declared which are payable in shares of Common Stock or Class B Common Stock,
dividends shall be declared which are payable at the same rate on both classes
of stock and such dividends shall be payable only in shares of Common Stock to
holders of the Common Stock and shall be payable only in shares of Class B
Common Stock to holders of the Class B Common Stock.

                 4.  Liquidation.  Upon any liquidation, dissolution or winding
up of the Corporation, whether voluntary or involuntary, after the payment in
full of all amounts to which holders of Preferred Stock shall be entitled, the
remaining assets of the Corporation to be distributed to the holders of the
capital stock of the Corporation shall be distributed ratably among the holders
of the shares of Common Stock and Class B Common Stock.

                 5.  Subdivision and Combination.  If the Corporation shall in
any manner subdivide (by stock split, stock dividend or otherwise) or combine
(by reverse stock split or otherwise) the outstanding shares of either the
Common Stock or the Class B Common Stock, the outstanding shares of the other
shall be proportionately subdivided or combined.

                 6.  Conversion.

                     (a)  General.  Subject to and upon compliance with the
provisions of this Section 4.2(B)(6), each holder of record of the Class B
Common Stock shall be entitled at any time and from time to time to convert any
or all of the shares of Class B Common Stock held by such holder into the same
number of shares of Common Stock; provided, however, that no holder of the
Class B Common Stock shall be entitled to convert any share or shares of Class
B Common Stock unless such holder represents in writing to the Corporation
that, as a result of such conversion, such holder and its affiliates, directly
or indirectly, would not own, control or have power to vote a greater quantity
of securities of any kind issued by the Corporation than such holder and its
affiliates are permitted to own, control or have power to vote under any law or
under any regulation, rule or other requirement of any governmental authority
at the time applicable to such holder and its affiliates.

                     (b)  Conversion Procedures.  Each conversion of shares of
Class B Common Stock into shares of Common Stock shall be effected by (and the
Corporation shall be obligated to issue such shares of Common Stock upon) the
surrender of the certificate or certificates representing such shares of Class
B Common Stock to be converted at the principal office of the Corporation (or
at such other office or agency of the Corporation as the Corporation may
designate by notice in writing to the holders of the Class B Common Stock or,
if such conversion shall be in connection with an underwritten public offering
of shares of Common Stock, at the location at which the Corporation shall agree
to deliver the shares of Common Stock subject to such offering) at any time
during its usual business hours, together with written notice by the holder of
such Class B Common Stock (i) stating that such holder desires to convert the
shares, or a stated number of the shares, of Class B Common Stock represented
by such certificate or certificates into shares of Common Stock and (ii)
representing that upon such conversion, such holder and its affiliates shall
not, directly or indirectly, own, control or have power to vote a greater
quantity of securities of any kind issued by the Corporation than such holder
and its affiliates are permitted to own, control or have power to vote under
any applicable law, regulation, rule or other governmental requirement.  Such
notice shall also state the name or names (with addresses) and denominations in
which the certificate or certificates for shares of Common Stock are to be
issued and shall include instructions for delivery





                                      -3-
<PAGE>   4
thereof.  In case such notice shall specify that the new certificates to be
issued are to be issued in a name or names other than that of the holder of
Class B Common Stock, such notice shall be accompanied by payment of all
transfer taxes, if any.  Promptly after such surrender and the receipt of such
written notice and payment of transfer taxes, if applicable, the Corporation
shall issue and deliver in accordance with such instructions the certificate or
certificates for the Common Stock issuable upon such conversion, and the
Corporation shall deliver to the converting holder a certificate representing
any shares of Class B Common Stock which were represented by the certificate or
certificates surrendered to the Corporation in connection with such conversion
but which were not converted.  Such conversion to the extent permitted by law
shall be deemed to have been effected as of the close of business on the date
on which such certificate or certificates have been surrendered, such notice
has been received and such transfer taxes paid, if applicable, and at such time
the rights of the holder of such Class B Common Stock (or specified portion
thereof) as such holder shall cease and the person or persons in whose name or
names the certificate or certificates for shares of Common Stock are to be
issued upon such conversion shall be deemed to have become the holder or
holders of record of the shares of Common Stock represented thereby.

                     (c)  Reservation of Shares, Validity, Etc.  The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock or its treasury shares, for the purpose of
issuance upon the conversion of the Class B Common Stock as provided in this
Section 4.2(B)(6) such number of shares of Common Stock as are then issuable
upon the conversion of all outstanding shares of Class B Common Stock (assuming
that all such shares of Class B Common Stock are held by persons entitled to
convert such shares fully into shares of Common Stock).  The Corporation
covenants that all shares of Common Stock which are issuable upon conversion
shall, when issued, be duly and validly issued, fully paid and nonassessable
and free from all taxes, liens and charges.  The Corporation shall take all
such action as may be necessary to assure that all such shares of Common Stock
may be so issued without violation of any law or any regulation, rule or other
requirement of any governmental authority applicable to the Corporation or any
requirement of any domestic securities exchange upon which shares of Common
Stock may be listed; provided, however, that the Corporation shall be entitled
to rely on the representations of the holders of the Class B Common Stock
required under subsections (a) or (b) of this Section 4.2(B)(6).  The
Corporation shall not take any action which would affect the number of shares
of Common Stock outstanding or issuable for any purposes unless immediately
following such action the Corporation would have authorized but unissued shares
of Common Stock or treasury shares, not then reserved or required to be
reserved for any purpose other than the purpose of issue upon conversion of the
Class B Common Stock, sufficient to meet the reservation requirements of the
first sentence of this subsection (c).

                     (d)  Registration and Listing.  If any shares of Common
Stock required to be reserved for purposes of conversion hereunder require,
before such shares may be issued upon conversion, registration with or approval
of any governmental authority under any federal or state law (other than any
registration under the Securities Act of 1933, as then in effect, or any
similar federal statute then in force, or any state securities law, required by
reason of any transfer involved in such conversion), or listing on any domestic
securities exchange, the Corporation shall, at its expense and as expeditiously
as possible, use its best efforts to cause such shares to be duly registered or
approved or listed, as the case may be.

                     (e)  Charges.  The issuance of certificates for shares of
Common Stock upon conversion of shares of Class B Common Stock shall be made
without charge to the holders of such shares of Class B Common Stock for any
issue tax in respect thereof or other cost incurred by the Corporation in
connection with such conversion and the related issue of shares of Common
Stock; provided, however, that the Corporation shall not be required to pay any
tax which may be payable in respect of any transfer involved in the issue and
delivery of any certificate in a name other than that of the holder of the
Class B Common Stock converted.

                     (f)  Converted or Otherwise Acquired Shares To Be Retired.
Any shares of Class B Common Stock which are converted into shares of Common
Stock pursuant to this Section 4.2(B)(6) or otherwise acquired by the Company
in any manner whatsoever shall be permanently retired promptly on the
acquisition thereof and shall not under any circumstances be reissued, and the
Corporation shall from time to time take such appropriate action as may be
necessary to reduce the authorized number of shares of Class B Common Stock
accordingly.

                 7.  Voting Rights.

                     (a)  General.  Except as otherwise provided by law or this
Article IV, the holders of the Common Stock shall be entitled to vote as a
class for the election or removal of all Directors of the Corporation and on
all other matters to be voted on by the stockholders of the Corporation and the
holders of the Class B Common Stock shall have no right to vote on matters to
be voted on by the stockholders of the Corporation, and the Class B Common
Stock shall not be included in determining the number of shares voting or
entitled to vote on such matters.

                     (b)  Special Voting Rights.  The holders of the Class B
Common Stock shall be entitled to vote on, and shall be included in determining
the number of shares of Common Stock and Class B Common Stock voting or
entitled to vote on, the following matters:  (i) any amendment to this Restated
Certificate of Incorporation, (ii) any sale, lease, transfer or other
disposition of all or substantially all of the property and assets of the
Corporation on which the holders of the Common Stock have the right to vote,
(iii) any merger or consolidation of the Corporation with or into any other
corporation on which the holders of the Common Stock have the right to vote,
and (iv) any liquidation, dissolution or winding up of the Corporation on which
the holders of the Common Stock have the right to vote.

                     (c)  Meeting Procedures.  At every meeting of the holders
of the Common Stock, such holders shall vote together as a class.  At every
meeting of the holders of the Common Stock and Class B Common Stock, at which
the holders of the Class B Common Stock are entitled to vote on any matter, the
holders of the Class B Common Stock and the holders of the Common Stock shall
vote thereon together as a single class; provided, however, that the holders of
the Class B Common Stock shall be entitled to vote separately as a class on any
amendment to the provisions pertaining to Class B Common Stock set forth in
this Article IV.B.

                     (d)  One Vote Per Share.  On all matters to be voted on by
the holders of Common Stock or the Class B Common Stock, the holders of such
class shall be entitled to one vote for each share thereof held of record.

                                   ARTICLE V

                          POWERS OF BOARD OF DIRECTORS

         5.1.  Expanded Powers of the Board.  In furtherance of, and not in
limitation of, the powers conferred by law, the Board of Directors is expressly
authorized and empowered:

              A.     to adopt, amend or repeal the Bylaws of the Corporation;
         provided, however, that the Bylaws adopted by the Board of Directors
         under the powers hereby conferred may be amended or repealed by the
         Board of Directors or by the stockholders entitled to vote with
         respect thereto; and

              B.     from time to time to determine whether and to what extent,
         and at what times and places, and under what conditions and
         regulations, the accounts and books of the Corporation, or any of
         them, shall be open to inspection of stockholders; and, except as so
         determined or as so provided in any Preferred Stock Designation, no
         stockholder shall have any right to inspect any account, book or
         document of the Corporation other than such rights as may be conferred
         by applicable law.

         5.2.  Powers Specified in Bylaws.  The Corporation may in its Bylaws
confer powers upon the Board of Directors in addition to the foregoing and in
addition to the powers and authorities expressly conferred upon the Board of
Directors by applicable law.

                                   ARTICLE VI

                    NO STOCKHOLDER ACTION BY WRITTEN CONSENT

         Subject to the rights of the holders of any series of Preferred Stock
as set forth in a Preferred Stock Designation to elect additional Directors
under specific circumstances, upon the closing of the Corporation's first
public offering of Common Stock under a registration statement filed with the
Securities and Exchange Commission, 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 stockholders of the Corporation and may not be
effected by any consent in writing of such stockholders.


                                  ARTICLE VII

                             ELECTION OF DIRECTORS

         7.1. Number, Election and Terms of Directors.  Subject to the rights
of the holders of Preferred Stock to elect additional Directors under specific
circumstances, the number of the Directors of the Corporation shall be fixed
from time to time by or pursuant to the Bylaws of the Corporation.  The
Directors, other than those who may be elected by the holders of Preferred
Stock, shall be classified with respect to the time for which they severally
hold office into three classes, as nearly their equal in number as possible, as
shall be provided in the manner specified in the Bylaws of the Corporation.  At
each annual meeting of the stockholders of the Corporation, the successors of
the class of Directors whose term expires at that meeting shall be elected by
plurality vote of all votes cast at such meeting to hold office for a term
expiring at the annual meeting of stockholders held in the third year following
the year of their election.

         7.2. Removal of Directors.  Until such time as The Prudential
Insurance Company of America ("Prudential") and its Affiliates (as defined) are
the record holders of shares of Common Stock and/or Class B Common Stock
representing less than 5% of the then issued and outstanding Common Stock, on a
Fully-Diluted Basis (as defined) that, when acquired by Prudential and/or its
Affiliates, had not been registered pursuant to the Securities Act of 1933, as
amended, any Director or the entire Board of Directors may be removed, with or
without cause, by the holders of a majority of the shares then entitled to vote
at an election of Directors and the holders of 25% or more of the outstanding
Common Stock shall have the right to call a special meeting of stockholders
solely for the purpose of removing any Director and filling any vacancy created
thereby.  Notwithstanding Article VI hereof, the removal of a director pursuant
to this Section 7.2 may be effected by the written consent of stockholders.

         7.3. Stockholder Nomination of Director Candidates and Introduction of
Business.  Advance notice of stockholder nominations for the election of
Directors and advance notice of business to be brought by stockholders before
an annual meeting shall be given in the manner provided in the Bylaws of the
Corporation.

         7.4. Newly Created Directorships and Vacancies.  Except as otherwise
provided for or fixed by or pursuant to the provisions of Article IV of this
Restated Certificate of Incorporation relating to the rights of the holders of
Preferred Stock to elect Directors under specified circumstances, newly created
directorships resulting from any increase in the number of Directors and any
vacancies on the Board of Directors resulting from death, resignation,
disqualification, removal or other cause shall be filled only by the
affirmative vote of a majority of the remaining Directors then in office, even
though less than a quorum of the Board of Directors.  Any Director elected in
accordance with the preceding sentence shall hold office for the remainder of
the full term of the class of Directors in which the new directorship was
created or the vacancy occurred and until such Director's successor shall have
been elected and qualified.  Notwithstanding the foregoing provisions of this
Section 7.4, until such time as Prudential and its Affiliates are the record
holders of shares of Common Stock and/or Class B Common Stock representing less
than 5% of the then issued and outstanding shares of Common Stock, on a
Fully-Diluted Basis that, when acquired by Prudential and/or its Affiliates,
had not been registered pursuant to the Securities Act of 1933, as amended, at
any meeting of stockholders at which action is taken resulting in the removal
of a Director, the vacancy on the Board of Directors resulting from such
removal may be filled by the holders of a majority of the





                                      -6-
<PAGE>   7
shares then entitled to vote at an election of Directors and, if so filled,
such Director shall hold office for the remainder of the full term of the class
of Directors in which the vacancy occurred and until such Director's successor
shall have been elected and qualified.  Notwithstanding Article VI hereof, any
action permitted to be taken at a meeting pursuant to the preceding sentence of
this Section 7.4 may be effected by the written consent of stockholders.

         7.5. Decrease in Number of Directors.  No decrease in the number of
Directors constituting the Board of Directors shall shorten the term of an
incumbent Director.

         7.6. No Requirement of Written Ballot.  The election of the Directors
may be conducted in any form adopted by the Board of Directors, and need not be
by written ballot.  In the event, however, that a majority of the stockholders
vote to require written ballots, written ballots shall be used.

         7.7  Certain Defined Terms.  As used in this Article VII, (i) the term
"Affiliate" shall mean a person that directly or indirectly through one or more
intermediaries, controls, or is controlled by, or is under common control with,
such person; (ii) the term "control" shall mean the power to cause the election
of a majority of the members of the board of directors or other governing body
of any entity; and (iii) the term "Fully-Diluted Basis" shall mean after giving
effect to the exercise, conversion and exchange of all securities or other
rights then exercisable or convertible into or exchangeable for Common Stock
(including, without limitation, any subscriptions, options, warrants,
conversions or other rights pursuant to any agreements, arrangements or
commitments of any kind obligating the Corporation to issue or sell any shares
of Common Stock or any securities exercisable or convertible into or
exchangeable for Common Stock).


                                  ARTICLE VIII

                                INDEMNIFICATION

         Each person who is or was a Director or officer of the Corporation, or
each such person who is or was serving at the request of the Board of Directors
or an officer of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
(including the heirs, executors, administrators or estate of such person),
shall be indemnified by the Corporation to the full extent permitted from time
to time by the DGCL 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 said law permitted
the Corporation to provide prior to such amendment) or any other applicable
laws as presently or hereafter in effect.  Without limiting the generality or
the effect of the foregoing, the Corporation may enter into one or more
agreements with any person which provide for indemnification greater or
different than that provided in this Article VIII.  Any amendment or repeal of
this Article VIII shall not adversely affect any right or protection existing
hereunder immediately prior to such amendment or repeal.


                                   ARTICLE IX

               NO MONETARY LIABILITY OF DIRECTORS TO STOCKHOLDERS

         To the full extent permitted by the DGCL or any other applicable laws
presently or hereafter in effect, no Director of the Corporation shall be
personally liable to the Corporation or its stockholders for or with respect to
any acts or omissions in the performance of his or her duties as a Director of
the Corporation.  Any repeal or modification of this Article Ninth shall not
adversely affect any right or protection of a Director of the Corporation
existing immediately prior to such repeal or modification.

                                   ARTICLE X

                                   AMENDMENT

         The Corporation reserves the right at any time and from time to time
to amend, alter, change or repeal any provision contained in this Restated
Certificate of Incorporation or a Preferred Stock Designation, 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 herein or
by applicable law, and all rights, preferences and privileges of whatsoever
nature conferred upon stockholders, Directors or any other persons whomsoever
