stock are as follows:

         A.       Preferred Stock

         The Preferred Stock may be issued from time to time by the Board of
Directors as shares of one or more series. Subject to the provisions hereof and
the limitations prescribed by law, the Board of Directors is expressly
authorized, prior to issuance, by adopting resolutions providing for the
issuance of, or providing for a change in the number of, shares of any
particular series and, if and to the extent from time to time required by law,
by filing a certificate pursuant to the General Corporation Law of Delaware (or
other law hereafter in effect relating to the same or substantially similar
subject matter), to establish or change the number of shares to be included in
each such series and to fix the voting powers and the designations and relative
powers, preferences and rights and the qualifications and limitations or
restrictions thereof relating to the shares of each such series. The authority
of the Board of Directors with respect to each series shall include, but not be
limited to, determination of the following:

                  (a) the distinctive serial designation of such series and the
         number of shares constituting such series, which number may be
         increased or decreased (but not below the number of then outstanding
         shares thereof) from time to time by like action of the Board of
         Directors;

                  (b) the rate and times at which, and the terms and conditions
         on which, dividends, if any, on Preferred Stock of each series shall be
         paid, the extent of the preference or relation, if any, of such
         dividends to the dividends payable on any other class or classes, or
         series of the same or other classes of stock, whether such dividends
         shall be cumulative or non-cumulative, and, if so, from which date or
         dates;

                  (c) whether the shares of such series shall be redeemable and,
         if so, the terms and conditions of such redemption, including the date
         or dates upon and after which such shares shall be redeemable, and the
         amount per share payable in case of redemption, which amount may vary
         under different conditions and at different redemption dates;

                  (d) the obligation, if any, of the Corporation to retire
         shares of such series, including the price or prices which the
         Corporation shall be obligated to pay therefor, and the terms of the
         sinking fund or redemption or purchase account, if any, to be provided
         for the shares of such series;

                  (e) whether shares of such series shall be convertible into,
         or exchangeable for, shares of stock of any other class or classes and,
         if so, the terms and conditions of


                                       2

         such conversion or exchange, including the price or prices or the rate
         or rates of conversion or exchange and the terms of adjustment, if any;

                  (f) whether the shares of such series shall have voting
         rights, in addition to the voting rights provided by law, and, if so,
         the terms of such voting rights (which voting rights may, without
         limiting the generality of the foregoing, include the right, voting as
         a series or by itself or together with other series of Preferred Stock
         as a class, to elect one or more Directors of the Corporation or to
         have one or more votes per share on any or all matters as to which a
         stockholder vote is required or permitted);

                  (g) the rights of the shares of such series in the event of
         voluntary or involuntary liquidation, dissolution or winding up of the
         Corporation, or in the event of a merger, distribution or sale of
         assets; and

                  (h) any other relative rights, powers, preferences,
         qualifications, limitations or restrictions thereof relating to such
         series.

         The number of authorized shares of Preferred Stock may be increased or
decreased by the affirmative vote of the holders of two-thirds (2/3) or more of
the Total Voting Power of the then outstanding shares of Voting Stock,
considered for this purpose as one class and without the separate vote of
holders of Preferred Stock as a class (it being understood that for purposes of
this Article Four, each share of the Voting Stock shall have the number of votes
granted to it pursuant to this Article Four). For the purposes of this Article
Four, Section 2A: (i) the term "Total Voting Power" shall mean the aggregate of
all votes of all outstanding shares of Voting Stock; and (ii) the term "Voting
Stock" shall mean the shares of all classes of capital stock of the Corporation
entitled to vote on increasing or decreasing the number of authorized shares of
Preferred Stock.

         The relative powers, preferences and rights of each series of Preferred
Stock in relation to the powers, preferences and rights of each other series of
Preferred Stock shall, in each case, be as fixed from time to time by the Board
of Directors in the resolution or resolutions adopted pursuant to authority
granted in Section 2A of this Article Four, and the consent, by class or series
vote or otherwise, of the holders of such of the series of Preferred Stock as
are from time to time outstanding shall not be required for the issuance by the
Board of Directors of any other series of Preferred Stock whether or not the
powers, preferences and rights of such other series shall be fixed by the Board
of Directors as senior to, or on a parity with, the powers, preferences and
rights of such outstanding series, or any of them; provided, however, that the
Board of Directors may provide in the resolution or resolutions as to any series
of Preferred Stock adopted pursuant to Section 2A of this Article Four that the
consent of the holders of a majority (or such greater proportion as shall be
therein fixed) of the outstanding shares of such series voting thereon shall be
required for the issuance of any or all other series of Preferred Stock.

         Subject to the provisions of the foregoing paragraph of this Section
2A, shares of any series of Preferred Stock may be issued from time to time as
the Board of Directors of the Corporation shall determine and on such terms and
for such consideration as shall be fixed by the Board of Directors.

         B.       Common Stock

         After the requirements with respect to preferential dividends on the
Preferred Stock (fixed in accordance with the provisions of Section 2A of this
Article Four), if any, shall have been met and after the Corporation shall have
complied with all the requirements, if any, with


                                       3

respect to the setting aside of sums as sinking funds or redemption or purchase
accounts (fixed in accordance with the provisions of Section 2A of this Article
Four), and subject further to any other conditions which may be fixed in
accordance with the provisions of Section 2A of this Article Four, then and not
otherwise the holders of Common Stock shall be entitled to receive such
dividends as may be declared from time to time by the Board of Directors.

         After distribution in full of the preferential amount, if any (fixed in
accordance with the provisions of Section 2A of this Article Four), to be
distributed to the holders of Preferred Stock in the event of voluntary or
involuntary liquidation, distribution or sale of assets, dissolution or
winding-up, of the corporation, the holders of the Common Stock shall be
entitled to receive all of the remaining assets of the Corporation, tangible and
intangible, of whatever kind available for distribution to stockholders ratably
in proportion to the number of shares of Common Stock held by them respectively.

         Except as may otherwise be required by law, each holder of Common Stock
shall have one vote in respect of each share of Common Stock held by him on all
matters voted upon by the stockholders.

         Shares of Common Stock may be issued from time to time as the Board of
Directors of the Corporation shall determine arid on such terms and for such
consideration as shall be fixed by the Board of Directors.

         Section 3. No holder of any shares of stock of the Corporation of any
class shall be entitled as such, as a matter of right, to subscribe for or
purchase any shares of stock of the Corporation of any class, whether now or
hereafter authorized or whether issued for cash, property or services or as a
dividend or otherwise, or to subscribe for or purchase any obligations, bonds,
notes, debentures, other securities or stock convertible into shares of stock of
the Corporation of any class or carrying or evidencing any right to purchase
shares of stock of any class.

                                  ARTICLE FIVE

         Section 1. The property, business and affairs of the Corporation, shall
be managed and controlled by the Board of Directors. The total number of
Directors of the Corporation shall be fixed by, or in the manner provided in,
the Bylaws.

         Section 2. A majority of the whole Board of Directors shall constitute
a quorum for the transaction of business, and, except as otherwise provided in
this Restated Certificate or the Bylaws, the vote of a majority of the Directors
present at a meeting at which a quorum is then present shall be the act of the
Board of Directors. As used in this Restated Certificate, the term "whole Board
of Directors" is hereby exclusively defined to mean the total number of
Directors which the Corporation would have if there were no vacancies.

         Section 3. The members of the Board of Directors, other than those who
may be elected by the holders of any Preferred Stock or series thereof, shall be
divided into three classes (to be designated as Class I, Class II and Class
III), with the terms of office of one class expiring each year. Subject to any
shorter or longer term which may be applicable to a director elected by any
series of Preferred Stock voting separately as a class, at each annual meeting
of stockholders the successors to the class of Directors whose term shall then
expire shall be elected to hold office for


                                       4

a term expiring at the third succeeding annual meeting and until their
respective successors shall be duly elected and qualified or until their
respective earlier resignation or removal.

         Section 4. Except for directorships created pursuant to Article Four
hereof relating to the rights of holders of Preferred Stock, or any series
thereof, and except for vacancies in such directorships, any vacancies in the
Board of Directors for any reason, and any newly created directorships resulting
from any increase in the number of Directors, may be filled only by the Board of
Directors, acting by a majority of the Directors then in office, although less
than a quorum, and any Directors so chosen shall hold office until the next
election of the class for which such Directors shall have been chosen and until
their successors shall be elected and qualified. No decrease in the number of
Directors shall shorten the term of any incumbent Director.

         Section 5. Notwithstanding any other provisions of this Restated
Certificate or the Bylaws of the Corporation (and notwithstanding the fact that
some lesser percentage may be specified by law, this Restated Certificate or the
Bylaws of the Corporation), any director or the entire Board of Directors of the
Corporation, except for directors elected by one or more series of Preferred
Stock, voting separately as a class, may be removed at any time, but only for
cause and only by the affirmative vote of the holders of at least a majority of
the Total Voting Power of the then outstanding shares of Voting Stock,
considered for this purpose as one class (it being understood that for purposes
of this Article Five, Section 5, each share of the Voting Stock shall have the
number of votes granted to it pursuant to Article Four of this Restated). For
the purposes of this Article Five, Section 5: (i) the term "Total Voting Power"
shall mean the aggregate of all votes of all outstanding shares of Voting Stock;
and (ii) the term "Voting Stock" shall mean the shares of all classes of capital
stock of the Corporation entitled to vote on removal of any director or the
entire Board of Directors in the manner provided in this Article Five, Section 5
(except that if the next succeeding sentence is operative, then the outstanding
shares of Preferred Stock shall not be considered "Voting Stock" for purposes of
this Article Five, Section 5). Notwithstanding the foregoing, and except as
otherwise required by law, whenever the holders of any one or more series of
Preferred Stock shall have the right, voting separately as a class, to elect one
or more Directors of the Corporation, the provisions of this Article Five shall
not apply with respect to the Director or Directors elected by such holders of
Preferred Stock.

         Section 6. There shall be no qualifications for election as Directors
of the Corporation, except that no person shall be eligible to stand for
election as a Director if he has been convicted of a felony by a court of
competent jurisdiction where such conviction is no longer subject to direct
appeal.

         Section 7. Elections of Directors need not be by ballot unless the
Bylaws of the Corporation shall so provide.

         Section 8. Subject to the rights of holders of Preferred Stock,
nominations for the election of Directors may be made by the Board of Directors
or a proxy committee appointed by the Board of Directors or by any stockholder
entitled to vote in the election of Directors generally. However, any
stockholder entitled to vote in the election of Directors generally may nominate
one or more persons for election as Directors at a meeting only if written
notice of such stockholder's intent to make such nomination or nominations has
been given, either by personal delivery or by United States mail, postage
prepaid, to the Secretary of the Corporation not later than (i) with respect to
an election to be held at an annual meeting of stockholders, one hundred twenty
(120) days in advance of the date of such meeting (as set forth in the
Corporation's Bylaws), and (ii) with respect to an election to be held at a
special meeting of stockholders for the


                                       5

date on which notice of such meeting is first given to stockholders. Each such
notice shall set forth: (a) the name and address of the stockholder who intends
to make the nomination and of the person or persons to be nominated; (b) a
representation that the stockholder is a holder of record of stock of the
Corporation entitled to vote at such meeting and intends to appear in person or
by proxy at the meeting to nominate the person or persons specified in the
notice; (c) the name and address, as they appear on the Corporation's books, of
such stockholder; (d) the class and number of shares of the Corporation which
are beneficially owned (as such term is defined in Section 4, Paragraph D of
Article Seven of this Restated Certificate) by such nominating stockholder and
each nominee proposed by such stockholder; (e) a description of all arrangements
or understandings between the nominating stockholder and each nominee and any
other person or persons (naming such person or persons) pursuant to which the
nomination or nominations are to be made by the stockholder; (f) such other
information regarding each nominee proposed by such stockholder as would have
been required to be included in a proxy statement filed pursuant to Regulation
14A (17 CFR 240.14a-1 et seq.) as then in effect under the Securities Exchange
Act of 1934, as amended, had the nominee been nominated, or intended to be
nominated, by the Board of Directors; and (g) the consent of each nominee to
serve as a Director of the Corporation if so elected. The chairman of the
meeting may refuse to acknowledge the nomination of any person not made in
compliance with the foregoing procedure.

         Section 9. Except as may be otherwise specifically provided in this
Article Five or in any resolution of the Board of Directors creating any series
of Preferred Stock adopted pursuant to Paragraph A of Section 2 of Article Four,
the term of office and voting power of each Director of the Corporation shall
not be greater than nor less than that of any other Director or class of
Directors of the Corporation.

                                   ARTICLE SIX

         Section 1. The original Bylaws of the Corporation shall be adopted in
any manner provided by law.

         Section 2. In furtherance, and not in limitation, of the powers
conferred by statute, the Board of Directors is expressly authorized to make,
adopt, alter, amend or repeal the Bylaws of the Corporation.

Certificate or the Bylaws of the Corporation, and notwithstanding the fact that
some lesser percentage may be specified by law, the stockholders of the
Corporation shall have the power to make, adopt, alter, amend or repeal the
Bylaws of the Corporation only upon the affirmative vote of two-thirds (2/3) or
more of the Total Voting Power of the then outstanding shares of Voting Stock,
considered for this purpose as one class (it being understood that for purposes
of this Article Six, each share of the Voting Stock shall have the number of
votes granted to it pursuant to Article Four of this Restated Certificate). For
purposes of this Article Six: (i) the term "Total Voting Power" shall mean the
aggregate of all votes of all outstanding shares of Voting Stock; and (ii) the
term "Voting Stock" shall mean the shares of all classes of capital stock of the
Corporation entitled to vote on making, adopting, altering, amending or
repealing the Bylaws of the Corporation.


                                       6

                                  ARTICLE SEVEN

certain Business Combinations (as hereinafter defined) and shall supersede any
other provision of this Restated Certificate or the Bylaws of the Corporation or
of law inconsistent therewith.

Restated Certificate (including, without limitation, any requirement that

Preferred Stock voting separately as a class) and except as otherwise expressly
provided in Section 3 of this Article Seven, any Business Combination (as

this Restated Certificate). Such affirmative vote shall be required
notwithstanding the fact that no vote may be required by law, or that a lesser
percentage may be specified by law or in any agreement with any national
securities exchange or otherwise.

         Section 3. The provisions of Section 2 of this Article Seven shall not
be applicable to any particular Business Combination, and such Business
Combination shall require only such affirmative vote as is required by law and
any other provision of this Restated Certificate, if the Business Combination
(as hereinafter defined) shall have been approved by a majority of the
Disinterested Directors (as hereinafter defined).

         Section 4.  For the purposes of this Article Seven:

         A.       "Business Combination" shall mean:

                  (i) any merger or consolidation of the Corporation or any

         with any of its Subsidiaries or any other transaction (whether or not
         with or into or otherwise involving any Interested Stockholder) which
         has the effect, directly or indirectly, of increasing the proportionate
         share of the outstanding shares of any class of Equity Security (as
