     Section 2.  Except for and subject to those rights expressly granted to the
holders of



                                  Exhibit 3.1

 
Preferred Stock, or any series thereof, by the Board of Directors of the
Corporation (the "Board of Directors"), pursuant to the authority hereby vested
in the Board of Directors or as provided by the laws of the State of Delaware,
the holders of the Corporation's Common Stock shall have exclusively all rights
of stockholders and shall possess exclusively all voting power.  Each holder of
Common Stock of the Corporation shall be entitled, on each matter submitted for
a vote to holders of Common Stock, to one vote for each share of Common Stock
standing in such holder's name on the books of the Corporation.

     Section 3.  The Board of Directors is hereby expressly authorized, at any
time and from time to time by a resolution or resolutions, to divide the shares
of Preferred Stock into one or more series, to issue from time to time in whole
or in part the shares of Preferred Stock or the shares of any series thereof,
and to fix and determine in the resolution or resolutions providing for the
issue of shares of Preferred Stock of a particular series the voting rights, if
any, of the holders of shares of such series, the designations, preferences and
relative, participating, optional and other special rights of such series, and
the qualifications, limitations and restrictions thereof, to the fullest extent
now or hereafter permitted by the laws of the State of Delaware.  The voting
rights, if any, of each such series and the preferences and relative,
participating, optional and other special rights of each such series, and the
qualifications, limitations and restrictions thereof, if any, may differ from
those of any and all other series.  Unless otherwise provided in the resolution
or resolutions of the Board of Directors providing for the issuance thereof,
shares of any series of Preferred Stock that shall be issued and thereafter
acquired by the Corporation through purchase, redemption, exchange, conversion
or otherwise shall return to the status of authorized but unissued Preferred
Stock.

     Without limiting the generality of the foregoing authority of the Board of
Directors, the Board of Directors from time to time may (if otherwise permitted
under the General Corporation Law of the State of Delaware):

          (a)  designate a series of Preferred Stock, which may be distinguished
by number, letter or title from other Preferred Stock of the Corporation;

          (b)  fix and thereafter increase or decrease (but not below the number
of shares thereof then outstanding) the number of shares of Preferred Stock that
shall constitute such series;

          (c)  provide for dividends on shares of Preferred Stock of such series
and, if provisions are made for dividends, determine the dividend rate and the
times at which holders of shares of Preferred Stock of such series shall be
entitled to receive the dividends, whether the dividends shall be cumulative
and, if so, from what date or dates, and the other conditions, if any, including
rights of priority, if any, upon which the dividends shall be paid;

          (d)  determine the rights, if any, to which holders of the shares of
Preferred Stock of such series shall be entitled in the event of any
liquidation, dissolution or winding up of the Corporation; provided, however,
that in the event of any such liquidation, dissolution or winding up of the
Corporation, the holders of the shares of Preferred Stock of such series shall
not be entitled to be paid out of the assets of the Corporation available for
distribution to its shareholders, whether from capital, surplus or earnings, an
amount in cash greater than $100.00 per share, plus accrued and unpaid

 
dividends to the date fixed for liquidation, dissolution or winding up, whether
or not declared.

          (e)  provide for the redemption or purchase of shares of Preferred
Stock of such series and, if provisions are made for redemption, determine the
time or times and the price or prices at which the shares of Preferred Stock of
such series shall be subject to redemption in whole or in part, and the other
terms and conditions, if any, on which shares of Preferred Stock of such series
may be redeemed or purchased;

          (f)  provide for a sinking fund or purchase fund for the redemption or
purchase of shares of Preferred Stock of such series and, if any such fund is so
provided for the benefit of such shares of Preferred Stock, the amount of such
fund and the manner of its application;

          (g)  determine the extent of the voting rights, if any, of the shares
of Preferred Stock of such series, including but not limited to the right of the
holders of such shares to vote as a separate class acting alone or with the
holders of one or more other series of Preferred Stock and the right to have
more (or less) than one vote per share;

          (h)  provide for whether or not the shares of Preferred Stock of such
series shall be convertible into, or exchangeable for, shares of any other class
or classes of capital stock, or any series thereof, of the Corporation and, if
so convertible or exchangeable, determine the conversion or exchange price or
rate, the adjustments thereof and the other terms and conditions, if any, on
which such shares of Preferred Stock shall be so convertible or exchangeable;
and
 
          (i)  provide for any other preferences, any relative, participating,
optional or other special rights, any qualifications, limitations or
restrictions thereof, or any other terms or provisions of shares of Preferred
Stock of such series as the Board of Directors may deem appropriate or
desirable.

     Section 4.  Shares of Common Stock or Preferred Stock may be issued by the
Corporation from time to time for such consideration, having a value of not less
than the par value, if any, thereof, as is determined from time to time by the
Board of Directors.  Any and all shares issued and for which full consideration
has been paid or delivered shall be deemed fully paid stock and the holder
thereof shall not be liable for any further payment thereon.

     ARTICLE V:  The following provisions are inserted for the management of the
business and for the conduct of the affairs of the Corporation and for the
purpose of creating, defining, limiting and regulating the powers of the
Corporation and its Directors and stockholders:

     Section 1.  The business and affairs of the Corporation shall be managed by
and under the direction of the Board of Directors.

     Section 2.  (a)  The Board of Directors shall consist of not less than
three (3) nor more than 20 (twenty) directors.  The exact number of directors
shall be determined from time to time by a resolution or resolutions adopted by
the affirmative vote of a majority of the entire Board of Directors.

 
     (b)  The Board of Directors shall be divided into three classes, as nearly
equal in number as the then total number of directors constituting the whole
board permits, with the term of office of one class expiring each year. At the
next election of directors, directors of the first class shall be elected to
hold office for a term expiring at the next succeeding annual meeting, directors
of the second class shall be elected to hold office for a term expiring at the
second succeeding annual meeting and the directors of the third class shall be
elected to hold office for a term expiring at the third succeeding annual
meeting. Subject to the foregoing, 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 a term expiring at the third succeeding annual
meeting and each director so elected shall hold office until his successor is
elected and qualified, or until his earlier resignation or removal.

     (c)  If the number of directors is changed, any increase or decrease in the
number of directors shall be apportioned among the three classes so as to make
all classes as nearly equal in number as possible, and the Board of Directors
shall decide which class shall contain an unequal number of directors.

     (d)  Notwithstanding the foregoing, whenever holders of any shares of
Preferred Stock, or any series thereof, shall be entitled, voting separately as
a class, to elect any directors, all directors so elected shall be allocated,
each time they are so elected, to the class whose term expires at the next
succeeding annual meeting of stockholders and the terms of all directors so
elected by such holders shall expire at the next succeeding annual meeting of
stockholders. The number of directors that may be elected by such holders of
Preferred Stock shall be in addition to the number of directors fixed pursuant
to paragraph (a) of this Section 2.

     Section 3.  Subject to the rights of the holders of any shares of Preferred
Stock, or any series thereof, newly created directorships resulting from an
increase in the number of directors or any vacancies on the Board of Directors
resulting from death, resignation, disqualification, removal from office,
retirement or other cause shall be filled solely by the affirmative vote of the
remaining directors then in office, even though less than a quorum, or by the
sole remaining director, and each director so chosen shall hold office for a
term expiring at the annual meeting of stockholders at which the term of the
class to which he has been elected expires and until such director's successor
shall have been duly elected and qualified.  No decrease in the authorized
number of directors shall shorten the term of any incumbent director.

     Section 4.  Any director may be removed from office with cause, by an
affirmative vote of the holders of a majority of the combined voting power of
the then outstanding shares of stock entitled to vote generally in the election
of directors, voting together as a single class.  Any director may be removed
from office with cause by the affirmative vote of a majority of the members of
the Board of Directors, other than the director who is subject to a removal
vote.

     Section 5.  Advance notice of stockholder nominations for the election of
directors and of business to be brought by stockholders before any meeting of
stockholders of the Corporation shall be given if required by, and in the manner
provided in, the By-laws.  At any annual meeting or special meeting of
stockholders of the Corporation, any such business shall be conducted as shall
have been brought before such meeting in the manner provided in the By-laws.

     Section 6.  The Board of Directors shall have the express power, without a
vote of stockholders, to adopt any By-law not inconsistent with this Restated
Certificate of Incorporation or with any By-law adopted by vote of the
stockholders of the Corporation, and to amend, alter

 
or repeal the By-laws of the Corporation other than any By-law adopted by vote
of the stockholders of the Corporation, except to the extent that the By-laws or
this Restated Certificate of Incorporation otherwise provide.  The Board of
Directors may exercise such power upon the affirmative vote of a majority of the
entire Board of Directors.  Stockholders may adopt any By-law, or amend, alter
or repeal the By-laws of the Corporation, upon the affirmative vote of the
holders of shares having at least a majority of the voting power of the then
outstanding shares of capital stock of the Corporation entitled (at all times
and without regard to the occurrence of a contingency) to vote generally on the
election of Directors and other matters submitted for stockholder approval,
voting together as a single class.

     Section 7.  No director shall be liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director;
provided, however, that to the extent required by the provisions of Section
102(b)(7) of the General Corporation Law of the State of Delaware or any
successor statute, as the same may be interpreted or amended from time to time,
or any other laws of the State of Delaware, nothing contained in this Section 7
shall eliminate or limit the liability of a director (a) for any breach of the
director's duty of loyalty to the Corporation or its stockholders, (b) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) under Section 174 of the General Corporation Law
of the State of Delaware, (d) for any transaction from which the director
derived an improper personal benefit or (e) for any act or omission occurring
prior to the date when this provision becomes effective.  If the General
Corporation Law of the State of Delaware hereafter is amended to authorize the
further elimination or limitation of the liability of directors, then the
liability of a director of the Corporation, in addition to the limitation
provided herein, shall be limited to the fullest extent permitted by such
amendment.  Any amendment, modification or repeal of this Section 7 shall be
prospective only, and shall not adversely affect any limitation of the liability
of a director existing at the time of such amendment, repeal or modification.

     ARTICLE VI:  (a) Each person who is or was or had agreed to become a
director or officer of the Corporation, and each person who is or was serving or
who had agreed to serve at the request of the Corporation as a director or
officer of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise (including the heirs, executor, administrators
or estate of such person), shall be indemnified by the Corporation, and (b) each
person who is or was or who had agreed to become an employee or agent of the
Corporation or who is or was serving or who had agreed to serve at the request
of the Corporation as an employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise (including the
heirs, executor, administrators or estate of such person) may be indemnified by
the Corporation, in each case in accordance with the By-laws, to the full extent
permitted from time to time by the General Corporation Law of the State of
Delaware 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 VI.  Any amendment or repeal of this Article VI shall not
adversely affect any right or protection existing hereunder immediately prior to
such amendment or repeal.

     ARTICLE VII:  No action shall be taken by the stockholders of the
Corporation except at a annual or special meeting of stockholders.

 
     ARTICLE VIII:  The Corporation reserves the right to amend or repeal any
provision contained in this Restated Certificate of Incorporation in the manner
now or hereafter prescribed by the laws of the State of Delaware, and all rights
herein conferred upon stockholders or Directors are granted subject to this
reservation.

     4.   This Restated Certificate of Incorporation has been duly adopted in
accordance with the provisions of Sections 242 and 245 of the General
Corporation Law of the State of Delaware and by unanimous written consent of the
sole stockholder in accordance with Section 228 of the General Corporation Law
