                      (formerly Great Lakes Delaware, Inc.,
                        incorporated on January 26, 1970)

This Certificate as duly adopted in accordance with the provisions of Section
245 of the Delaware General Corporation Law and only restates and integrates and
does not further amend the provisions of the Corporation's Certificate of

Certificate of Incorporation.

--------------------------------------------------------------------------------



FIRST.   The name of the Corporation is Great Lakes Chemical Corporation.

SECOND.  The address of its registered office in the State of Delaware is 229
         South State Street in the City of Dover, County of Kent. The name of
         its registered agent at such address is United States Corporation
         Company.

THIRD.   The nature of the business to be conducted or promoted and the purposes
         of the Corporation are to engage in any lawful act or activity for
         which corporations may be organized under the General Corporation Law
         of Delaware.

FOURTH.  The total number of shares of capital stock which the Corporation shall
         have authority to issue is two hundred million shares (200,000,000) of
         Common Stock with a par value of $1.00 per share.

         No holder of stock of any class, now or hereafter authorized, shall
         have any preemptive right to subscribe for or purchase, or have offered
         to him for subscription or purchase, stock of any class, securities
         convertible into stock of any class, or warrants or other evidences of
         optional rights to purchase stock of any class, whether issued for cash
         or other consideration.

FIFTH.   In furtherance and not in limitation of the powers conferred by
         statute, the Board of Directors is expressly authorized:
<PAGE>   2
                  (a)      To make, alter or repeal the By-laws of the
                           Corporation; and

                  (b)      To authorize and cause to be executed mortgages and
                           liens upon the real and personal property of the
                           Corporation.

SIXTH.           (a)       The number of directors shall be not less than 3 nor
                           more than 11. The exact number of directors shall be
                           such as from time to time shall be fixed by, and in a
                           manner set forth in, the By-laws of the Corporation.
                           No decrease in the number of directors shall shorten
                           the term of any incumbent director.

                  (b)      The directors shall be classified with respect to the
                           time for which they shall hold office by dividing
                           them into three classes, each consisting, as nearly
                           as may be possible, of one-third of the whole number
                           of the Board of Directors. At each annual meeting of
                           the stockholders, the successors to the directors
                           whose terms shall expire that year shall be elected
                           to hold office for the term of three years, so that
                           the term of office of one class of the directors
                           shall expire in each year. In any event, each
                           director of the Corporation shall hold office until
                           his successor is duly elected and qualified, subject,
                           however, to prior death, resignation, retirement, or
                           removal from office. If the number of directors is
                           changed, any increase or decrease shall be
                           apportioned among the classes so as to maintain the
                           number of directors in each class as nearly equal as
                           possible, but in no case shall a decrease in the
                           number of directors shorten the term of any incumbent
                           director. Any vacancy in the Board of Directors or
                           newly created directorship resulting from any
                           increase in the number of directors may be filled by
                           a majority of the directors then in office, excluding
                           any directors who shall theretofore have resigned
                           effective as of a future date, although less than a
                           quorum.

                  (c)      No director shall be removed from the Board of
                           Directors by action of the stockholders of the
                           Corporation during his appointed term other than for
                           cause.

                  (d)      Advance notice of stockholder nominations for the
                           election of directors shall be given in the manner
                           provided by the By-laws.

SEVENTH. Whenever a compromise or arrangement is proposed between the
         Corporation and its creditors or any class of them and/or between the
         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 the Corporation or of any creditor or
         stockholder thereof, or on the application of any receiver or receivers
         appointed for the Corporation under the provisions of Section 291 of
         Title 8 of the Delaware Code or on the application of
<PAGE>   3
                  trustees in dissolution or of any receiver or receivers
                  appointed for the 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 the 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 the Corporation, as the case may
                  be, agree to any compromise or arrangement and to any
                  reorganization of the 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 the Corporation, as
                  the case may be, and also on the Corporation.

EIGHTH.           The books of the Corporation may be kept (except as may be
                  otherwise required by law) 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.
                  Election of directors need not be by written ballot unless the
                  By-laws of the Corporation shall so provide.

NINTH.            The Corporation shall indemnify the directors and the officers
                  to the fullest extent permitted by the Delaware General
                  Corporation law. Directors of the Corporation, to the fullest
                  extent permitted by the Delaware General Corporation law,
                  shall not be liable to the Corporation of its stockholders for
                  monetary damages for breach of their fiduciary duty as a
                  director.

TENTH.            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 all rights conferred upon stockholders herein are
                  granted subject to this reservation.

ELEVENTH.         None of the following transactions may be effectuated unless a
                  meeting of stockholders of the Corporation is held to act
                  thereon and the votes of the stockholders of its voting
                  securities representing at least two-thirds of the votes
                  entitled to be cast are cast in favor thereof:

                  (a)      An acquisition by the Corporation of stock of an
                           Interested Party;

                  (b)      A sale, lease or exchange of all or the major portion
                           of the assets of the Corporation or an Interested
                           Party to the other;

                  (c)      A merger or consolidation to which the Corporation

                  provision of this Certificate of Incorporation, any action
                  required or permitted to be taken by the stockholders of the
                  Corporation, whether voting as a class of otherwise, must be
                  taken at a duly called annual or special meeting of the
                  stockholders of the Corporation and may not be taken by

                  alter, change or repeal any of the provisions of this Article
                  Twelfth unless such amendment, in addition to receiving any
