                                 voluntary dissolution than the case of
                                 involuntary dissolution; and

                           (9)   any other relative rights, preferences or

                   6. (a) At the 1987 annual meeting of stockholders, the
         directors elected to serve on the corporation's board of directors
         shall be divided into three classes, designated Class I, Class II and
         Class III. Each class shall consist, as nearly as may be possible, of
         one-third of the total number of directors constituting the whole board
         of directors. Class I directors shall be elected for a one-year term,
         Class II directors for a two-year term and Class III directors for a
         three-year term. At each succeeding annual meeting of stockholders
         beginning in 1988, successors to the class of directors whose term
         expires at that annual meeting shall be elected for a three-year term.

                      (b) Notwithstanding the foregoing, whenever the holders of
         any one or more classes or series of Preferred Stock issued by the
         corporation shall have the right, pursuant to Section 4(b) hereof,
         voting separately by class or series, to elect directors at an annual
         or special meeting of stockholders, the election, term of office,

         filling of vacancies and other features of such directorships shall be
         governed by the terms applicable thereto, and such directors so elected
         shall not be divided into classes pursuant to Section 6(a) unless
         expressly provided by the terms of such Preferred Stock.

                      (c) Subject to the rights of the holders of any one or
         more classes or series of Preferred Stock issued by the corporation,
         any director may be removed from office, with or without cause, only by
         the affirmative vote of the holders of eighty percent (80%) 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.

                   7. Subject to the rights of holders of any one or more
         classes or series of Preferred Stock issued by the corporation,
         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 generally in the
         election of directors 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, ninety (90)
         days in advance of such meeting, and (ii) with respect to an election
         to be held at a special meeting of stockholders for the election of
         directors, the close of business on the seventh day following the 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) a
         description of all arrangements or understandings between the
         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; (d) such other information regarding
         each nominee proposed by such stockholder as would be required to be
         included in a proxy statement filed pursuant to the proxy rules of the
         Securities and Exchange Commission, had the nominee been nominated, or
         intended to be nominated, by the board of directors; and (e) the

                                     - 5 -
   10
         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.

                   8. (a) In addition to any affirmative vote required by law or
         this Restated Certificate of Incorporation or the By-Laws of the
         corporation, and except as otherwise expressly provided in Section
         8(b), a Business Transaction (as hereinafter defined) with, or proposed
         by or on behalf of, any Interested Stockholder (as hereinafter defined)
         or any Affiliate or Associate (as hereinafter defined) of any
         Interested Stockholder or any person who thereafter would be an
         Affiliate or Associate of such Interested Stockholder shall require the
         affirmative vote of not less than a majority of the votes entitled to
         be cast by the holders of all the then outstanding shares of Voting
         Stock (as hereinafter defined), voting together as a single class,
         excluding Voting Stock beneficially owned by such Interested
         Stockholder. Such affirmative vote shall be required notwithstanding
         the fact that no vote may be required, or that a lesser percentage or
         separate class vote may be specified by law or otherwise.

                      (b) The provisions of Section 8(a) shall not be applicable
         to any particular Business Transaction, and such Business Transaction
         shall require only such affirmative vote, if any, as is required by law
         or by any other provision of this Restated Certificate of Incorporation
         or the By-Laws of the corporation, or otherwise, if the Business
         Transaction shall have been approved (whether such approval is made
         prior to or subsequent to the acquisition of, or announcement or public
         disclosure of the intention to acquire, beneficial ownership of the
         Voting Stock that caused the Interested Stockholder to become an
         Interested Stockholder), either specifically or as a transaction which
         is within an approved category of transactions, by a majority of the
         Disinterested Directors (as hereinafter defined).


                      (c) The following definitions shall apply with respect to
         this Section 8:

                  (1) The term "Business Transaction" shall mean:

                      (A) any merger or consolidation of the corporation or any
                 Subsidiary (as hereinafter defined) with (i) any Interested
                 Stockholder or (ii) any other company (whether or not itself an
                 Interested Stockholder) which is or after such merger or
                 consolidation would be an Affiliate or Associate of an
                 Interested Stockholder; or

                                     - 6 -
   11
                      (B) any sale, lease, exchange, mortgage, pledge, transfer

         Association of Securities Dealers Automated Quotation System (NASDAQ),
         the New York Stock Exchange or such other market on which the
         corporation's shares are publicly traded, or if no such quotations are

         the power and duty to determine for the purposes of this Section 8 on
         the basis of information known to them after reasonable inquiry, all

         shares of Capital Stock or other securities beneficially owned by any

         an Interested Stockholder or an Affiliate or Associate of an Interested
         Stockholder, (5) whether the assets that are the subject of any

         in any Business Transaction has, an aggregate Fair Market Value of
         $4,000,000 or more, and (6) whether the assets or securities that are
         the subject of any Business Transaction constitute a Substantial Part.
         Any such determination made in good faith shall be binding and
         conclusive on all parties.

                      (e) Nothing contained in this Section 8 shall be construed
         to relieve any Interested Stockholder from any fiduciary obligation
         imposed by law.

                      (f) For the purposes of this Section 8, a Business
         Transaction or any proposal to amend, repeal or adopt any provision of
         this Restated Certificate of

         Action") is presumed to have been proposed by, or on behalf of, an
         Interested Stockholder or an Affiliate or Associate of an Interested
         Stockholder or a person who thereafter would become such if (1) after
         the Interested Stockholder became such, the Proposed Action is proposed
         following the election of any director of the corporation who, with
         respect to such Interested Stockholder, would not qualify to serve as a
         Disinterested Director or (2) such Interested Stockholder, Affiliate,
         Associate or person votes for or consents to the adoption of any such
         Proposed Action, unless as to such Interested Stockholder, Affiliate,
         Associate or person a majority of the Disinterested Directors makes a
         good faith determination that such Proposed Action is not proposed by
         or on behalf of such Interested Stockholder, Affiliate, Associate or
         person, based on information known to them after reasonable inquiry.

                      (g) Notwithstanding any other provision of this Restated
         Certificate of Incorporation or the By-Laws of the corporation (and
         notwithstanding the fact that a lesser percentage or separate class
         vote may be specified by law, this Restated Certificate of
         Incorporation or the By-Laws of the corporation), any proposal to amend
         or repeal this Section 8 of this Restated Certificate of Incorporation

         by such Interested Stockholder; provided, however, that this Section
         8(g) shall not apply to, and such majority vote shall not be required
         for, any amendment, repeal or adoption recommended by a majority of the
         Disinterested Directors.

                  9. Notwithstanding anything contained in this Restated
         Certificate of Incorporation to the contrary, the affirmative vote of

         shares of the corporation entitled to vote generally in the election of
         directors, voting together in a single class, shall be required to
         alter, amend or adopt any provision inconsistent with Sections 6 and 7
         hereof.

                  10. 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

                                     - 11 -
   16
         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

         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.

                  11. 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 the stockholders herein are granted
         subject to this reservation."

         (d) This Restated Certificate of Incorporation was duly adopted by vote
of the stockholders in accordance with Sections 242 and 245 of the General
Corporation Law of the State of Delaware.

         (e) This Restated Certificate of Incorporation shall be effective on
