RESTATED CERTIFICATE OF INCORPORATION

OF

CATERPILLAR INC.


Caterpillar Inc., a corporation organized and existing under the laws 
of the State of Delaware, hereby certifies as follows:

1.   The name of the corporation is Caterpillar Inc.  The date of filing
     its original Certificate of Incorporation with the Secretary of 
     State was March 12, 1986.

2.   This Restated Certificate of Incorporation restates and integrates 
     and further amends the provisions of the Certificate of 
     Incorporation of this corporation by amending paragraph (a) of 
     Article FOURTH to increase the total authorized shares and the 
     authorized common stock.

3.   The text of the Certificate of Incorporation as amended or 
     supplemented heretofore is hereby further amended to read as herein
     set forth in full:

          FIRST:  The name of this corporation is Caterpillar Inc.

          SECOND:  The address of the registered office of the 
     corporation in the State of Delaware is Corporation Trust Center, 
     1209 Orange Street, in the City of Wilmington, County of New Castle,
     and the name of its registered agent at that address is The 
     Corporation Trust Company.

          THIRD:  The purpose of the corporation is to engage in any 
     lawful act or activity for which corporations may be organized 
     under the General Corporation Law of Delaware.

          FOURTH:  (a) The corporation is authorized to issue two 
     stock."  The total number of such shares shall be nine hundred and 
     five million (905,000,000), all of which shares shall have a par 
     value of $1.00 per share.  The total number of shares of common 
     stock authorized to be issued shall be nine hundred million 
     (900,000,000) and the total number of shares of preferred stock 
     authorized to be issued shall be five million (5,000,000).

     (b) The shares of preferred stock may be issued from time to time
     in one or more series.  The Board of Directors is hereby authorized 
     to establish from time to time by resolution or resolutions the 
     number of shares to be included in each such series, and to fix 
     the designation, powers, preferences and rights of the shares of 
     each such series and the qualifications, limitations or restrictions
     thereof, including but not limited to the fixing or alteration of 
     the dividend rights, dividend rate or rates, conversion rights, 
     voting rights, rights and terms of redemption (including sinking 
     fund provisions), the redemption price or prices, and the 
     liquidation preferences of any wholly unissued series of shares of 
     preferred stock, and the number of shares constituting any such 
     series and the designation thereof, or any or all of them; and to 
     increase or decrease the number of shares of any series subsequent
     to the issue of shares of that series, but not below the number of 
     shares of such series then outstanding.  In case the number of 
     shares of any series shall be so decreased, the shares constituting 
     such decrease shall resume the status which they had prior to the 
     adoption of the resolution originally fixing the number of shares 
     of such series.

          FIFTH:  In furtherance and not in limitation of the powers 
     conferred by statute, the Board of Directors shall have power to 
     make, alter, amend and repeal the bylaws (except so far as the 
     bylaws adopted by the stockholders shall otherwise provide).  
     Any bylaws made by the Board of Directors under the powers conferred
     hereby may be altered, amended or repealed by the Board of Directors
     or by the stockholders.  Notwithstanding the foregoing and anything 
     contained in this Certificate of Incorporation to the contrary, 
     Sections 1(b)(ii), 1(c) and 3(e) of Article II, and Section 1 of 
     Article III of the bylaws shall not be altered, amended or repealed,
     and no provisions inconsistent therewith shall be adopted, without 
     the affirmative vote of the holders of not less than seventy-five 
     percent (75%) of the outstanding stock of the corporation entitled 
     to vote generally in the election of directors, voting together as 
     a single class (it being understood that for the purposes of this 
     Article FIFTH, each share shall have one vote except as otherwise 
     provided in accordance with Article FOURTH).

          SIXTH:  (a) The number of directors which shall constitute the 
     whole Board of Directors of this corporation shall be as specified 
     in the bylaws of the corporation, subject to the provisions of 
     Article FIFTH herein and this Article SIXTH.

     (b) The Board of Directors shall be and is divided into three 
     classes:  Class I, Class II and Class III, which shall be as nearly 
     equal in number as possible.  Each director shall serve for a term 
     ending on the date of the third annual meeting of stockholders 
     following the annual meeting at which the director was elected, 
     provided, however, that each initial director in Class I shall hold 
     office until the annual meeting of stockholders in 1987; each 
     initial director in Class II shall hold office until the annual 
     meeting of stockholders in 1988; and each initial director in 
     Class III shall hold office until the annual meeting of stockholders
     in 1989.  Notwithstanding the foregoing provisions of this Article,
     each director shall serve until his successor is duly elected and 
     qualified or until his death, resignation or removal.

     (c) In the event of any increase or decrease in the authorized 
     number of directors, the newly created or eliminated directorships 
     resulting from such increase or decrease shall be apportioned by 
     the Board of Directors among the three classes of directors so as 
     to maintain such classes as nearly equal as possible.  No decrease 
     in the number of directors constituting the Board of Directors 
     shall shorten the term of any incumbent director.

     (d) 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 by the affirmative vote of a majority 
     of the remaining directors then in office (and not by stockholders),
     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.

     (e) Any director may be removed from office without cause but 
     only by the affirmative vote of the holders of not less than 
     seventy-five percent (75%) of the outstanding stock of the 
     corporation entitled to vote generally in the election of directors,
     voting together as a single class (it being understood that for 
     the purpose of this Article SIXTH, each share shall have one vote 
     except as otherwise provided in accordance with Article FOURTH).

     (f) Notwithstanding the foregoing, whenever the holders of any 
     one or more classes or series of stock issued by this corporation 
     having a preference over the common stock as to dividends or upon 
     liquidation, shall have the right, 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, 
     terms of removal and other features of such directorships shall be 
     governed by the terms of Article FOURTH and the resolution or 
     resolutions establishing such class or series adopted pursuant 
     thereto and such directors so elected shall not be divided into 
     classes pursuant to this Article SIXTH unless expressly provided by 
     such terms.

          SEVENTH:  (a) 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 such holders and may not be 
     effected by any consent in writing by such holders.

     (b) Special meetings of the stockholders of this corporation for 
     any purpose or purposes may be called at any time by the Chairman 
     of the Board or the President, or by the Board of Directors pursuant
     to a resolution approved by a majority of the entire Board of 
     Directors, but such special meetings may not be called by any other 
     person or persons.

     (c) Advance notice of stockholder nominations for the election of 
     directors shall be given in the manner provided in the bylaws of 
     this corporation.

     (d) Election of directors need not be by written ballot unless the 
     bylaws of this corporation shall so provide.

          EIGHTH:  The corporation reserves the right to amend, alter, 
     change or repeal any provision contained in this Certificate of 
     Incorporation, in the manner now or hereafter prescribed by statute
     and this Certificate of Incorporation, and all rights conferred on
     stockholders herein are granted subject to this reservation.  
     Notwithstanding the foregoing, the affirmative vote of not less 
     than seventy-five percent (75%) of the total voting power of all 
     outstanding shares of stock in this corporation entitled to vote 
     generally in the election of directors voting together as a single 
     class (it being understood that for the purposes of this Article 
     EIGHTH, each share shall have one vote except as otherwise provided 
     in accordance with Article FOURTH) shall be required to alter, 
     amend or repeal, or adopt any provisions inconsistent with the 
     provisions set forth in Articles FIFTH, SIXTH, SEVENTH, and this 
     Article EIGHTH.

          NINTH:  No director shall be personally liable to the 
     corporation or any stockholders for monetary damages for breach of 
     fiduciary duty as a director, except for any matter in respect of 
     which such director shall be liable under Section 174 of Title 8 
     of the Delaware Code (relating to the Delaware General Corporation 
     Law) or any amendment thereto or any successor provision thereto 
     or shall be liable by reason that, in addition to any and all other 
     requirements for such liability, such director (i) shall have 
     breached the duty of loyalty to the corporation of its stockholders,
     (ii) shall not have acted in good faith, or, in failing to act, 
     shall not have acted in good faith, (iii) shall have acted in a 
     manner involving intentional misconduct or a knowing violation of 
     law or, in failing to act, shall have acted in a manner involving 
     intentional misconduct or a knowing violation of law, or (iv) shall 
     have derived an improper personal benefit.  Neither the amendment 
     nor repeal of this Article NINTH, nor the adoption of any provision 
     of the Certificate of Incorporation inconsistent with this Article 
     NINTH, shall eliminate or reduce the effect of this Article NINTH 
     in respect of any matter occurring, or any cause of action, suit 
     or claim that, but for this Article NINTH would accrue or arise,
     prior to such amendment, repeal or adoption of an inconsistent 
     provision.

4.   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.

to be signed by Donald V. Fites, its Chairman of the Board of Directors,
