           Except where otherwise set forth in the resolution or
      resolutions adopted by the Board of Directors providing for the
      issuance of any series of Preferred Stock, the number of shares
      comprising such series may be increased or decreased (but not
      below the number of shares then outstanding) from time to time by
      like action of the Board of Directors.  The shares of Preferred
      Stock of any one series shall be identical with the other shares
      in such series in all respects except as to the dates from and
      after which dividends thereon shall cumulate, if cumulative.

           Shares of any series of Preferred Stock which have been
      redeemed (whether through the operation of a sinking fund or
      otherwise) or purchased by the Corporation, or which, if
      convertible or exchangeable, have been converted into or exchanged
      for shares of stock of any other class or classes shall have the
      status of authorized and unissued shares of Preferred Stock and
      may be reissued as a part of the series of which they were
      originally a part or may be reclassified and reissued as part of a
      new series of Preferred Stock to be created by resolution or
      resolutions of the Board of Directors or as part of any other
      series of Preferred Stock, all subject to the conditions or
      restrictions on issuance set forth in the resolution or
      resolutions adopted by the Board of Directors providing for the
      issuance of any series of Preferred Stock and to any filing
      required by law.

           Subject to the rights of any outstanding shares of any series
      of Preferred Stock, this Restated Certificate of Incorporation may
      be amended from time to time in a manner that would solely modify
      or change the relative powers, preferences and rights and the
      qualifications and limitations or restrictions of any issued
      shares of any series of Preferred Stock then outstanding with the
      only required vote or consent for approval of such amendment being
      the affirmative vote or consent of the holders of a majority of
      the outstanding shares of the series of Preferred Stock so
      affected provided that the powers, preferences and rights and the
      qualification and limitations or restrictions of such series after
      giving effect to such amendment are no greater than the powers,
      preferences and rights and the qualifications and limitations or
      restrictions permitted to be fixed and determined by the Board of
      Directors with respect to the establishment of any new series of
      shares of Preferred Stock pursuant to the authority vested in the
      Board of Directors by this Article 4.  Approval of any such
      amendment by the holders of the Common Stock shall not be required
      and any such amendment shall be deemed not to have affected the
      holders of the Common Stock adversely.

           The number of authorized shares of Preferred Stock may be
      increased or decreased by the affirmative vote of the holders of a
      majority of the stock of the Corporation entitled to vote without
      the separate vote of holders of Preferred Stock as a class.

                                  COMMON STOCK

           Subject to all of the rights of the Preferred Stock, and
      except as may be expressly provided with respect to the Preferred
      Stock herein, by law or by the Board of Directors pursuant to this
      Article 4:

                 (a) dividends may be declared and paid or set
            apart for payment upon Common Stock out of any assets
            or funds of the Corporation legally available for the
            payment of dividends and may be payable in cash, stock
            or otherwise;

                 (b) the holders of Common Stock shall have the
            exclusive right to vote for the election of directors
            and on all other matters requiring stockholder action,

                 (c) upon the voluntary or involuntary
            liquidation, dissolution or winding up of the
            Corporation, the net assets of the Corporation shall
            be distributed pro rata to the holders of Common Stock
            in accordance with their respective rights and
            interests to the exclusion of the holders of the
            Preferred Stock.

     5. The Corporation is to have perpetual existence.

     6. In furtherance and not in limitation of the powers conferred by
statute, the board of directors is expressly authorized:

           To set apart out of any of the funds of the Corporation
      available for dividends a reserve or reserves for any proper
      purpose and to abolish any such reserve in the manner in which it
      was created.

           By a majority vote of the whole board, to designate one or
      more committees. Any such committee, to the extent provided in the
      resolution of the board of directors, or in the by-laws of the
      Corporation, shall have and may exercise all the powers and
      authority of the board of directors in the management of the
      business and affairs of the Corporation, and may authorize the
      seal of the Corporation to be affixed to all papers which may
      require it; but no such committee shall have the power or
      authority in reference to amending the certificate of
      incorporation (except that a committee may, to the extent
      authorized in the resolution or resolutions providing for the
      issuance of shares of stock adopted by the board of directors as
      provided in Section 151(a) of the Delaware General Corporation
      Law, fix any of the preferences or rights of such shares relating
      to dividends, redemption, dissolution, any distribution of assets
      of the Corporation or the conversion into, or the exchange of such
      shares for, shares of any other class or classes, or any other
      series of the same or any other class or classes of stock of the
      Corporation), adopting an agreement of merger or consolidation
      under Section 251 or 252 of the Delaware General Corporation Law,
      recommending to the stockholders the sale, lease or exchange of
      all or substantially all of the Corporation's property and assets,
      recommending to the stockholders a dissolution of the Corporation
      or a revocation of a dissolution, or amending the bylaws of the
      Corporation; and, unless the resolution, bylaws or certificate of
      incorporation expressly so provides, no such committee shall have
      the


                                      A-4


<PAGE>   7



      power or authority to declare a dividend, to authorize the
      issuance of stock or to adopt a certificate of ownership and
      merger pursuant to Section 253 of the Delaware General Corporation
      Law.

           When and as authorized by the stockholders in accordance with
      statute, to sell, lease or exchange all or substantially all of
      the property and assets of the Corporation, including its good
      will and its corporate franchises, upon such terms and conditions
      and for such consideration, which may consist in whole or in part
      of money or property including shares of stock in, and/or other
      securities of, any other corporation or corporations, as its board
      of directors shall deem expedient and for the best interest of the
      Corporation.

     7. Elections of directors need not be by written ballot unless the by-laws
of the Corporation shall so provide.

     Meetings of stockholders may be held within or without the State of
Delaware, as the by-laws may provide.  The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
board of directors or in the by-laws of the Corporation.

     Whenever a compromise or arrangement is proposed between this Corporation
and its creditors or any class of them and/or between this Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of this
Corporation or of any creditor or stockholder thereof or on the application of
any receiver or receivers appointed for this Corporation under the provisions
of Section 291 of Title 8 of the Delaware Code or on the application of
trustees in dissolution or of any receiver or receivers appointed for this
Corporation under the provisions of Section 279 of Title 8 of the Delaware Code
order a meeting of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of this Corporation, as the case may be,
to be summoned in such manner as the said court directs.  If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this Corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this Corporation, as the case may be,
and also on this Corporation.

     8. All of the powers of the Corporation, insofar as the same may be
lawfully vested by this Restated Certificate of Incorporation in the Board of
Directors of the Corporation, are hereby conferred upon the Board of Directors
of the Corporation.

     In furtherance and not in limitation of the foregoing provisions of this
Article 8, and for the purpose of the orderly management of the business and
the conduct of the affairs of the Corporation, the Board of Directors of the
Corporation shall have the power to adopt, amend or repeal from time to time
any provision of the by-laws of the Corporation (including, without limitation,
by-laws governing the conduct of, and the matters which may properly be brought
before, meetings of the stockholders and by-laws specifying the manner and
extent to which prior notice shall be given of the submission of proposals to
be submitted at any meeting of stockholders or of nominations of


                                      A-5

elections of directors to be held at any such meeting) by the vote of a
majority of the entire Board of Directors, subject to the right of the
stockholders of the Corporation entitled to vote thereon to adopt, amend or
repeal by-laws of the Corporation.  In addition to any requirements of law and
any other provision of this Restated Certificate of Incorporation or any
resolution or resolutions of the Board of Directors adopted pursuant to Article
4 of this Restated Certificate of Incorporation (and notwithstanding the fact
that a lesser percentage may be specified by law, this Restated Certificate of
Incorporation or any such resolution or resolutions), the affirmative vote of
the holders of 80% or more of the combined voting power of the then outstanding
shares of stock of all classes and series of stock the holders of which are
entitled to vote generally in the election of directors, voting together as a
single class, shall be required to adopt, amend, alter or repeal any provision
of the by-laws.

     9. The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Restated Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

     10. To the fullest extent that the General Corporation Law of the State of
Delaware as it exists on the date hereof and as it may hereafter be amended
permits the limitation or elimination of the liability of directors, no
director of the Corporation shall be personally liable to the Corporation or
its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (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 the General Corporation Law of the State of
Delaware, or (iv) for any transaction from which the director derived an
improper personal benefit.  No amendment to or repeal of this Article shall
apply to or have any effect on the liability or alleged liability of any
director of the Corporation for or with respect to any acts or omissions of
such director occurring prior to such amendment or repeal.
