                      THE JEAN COUTU GROUP (PJC) USA, INC.

     The Jean Coutu Group (PJC) USA, Inc., a corporation organized and existing
under and by virtue of the General Corporation Law of the State of Delaware (the
"CORPORATION"), DOES HEREBY CERTIFY:

     FIRST: That the sole Director of the Corporation, by written consent, filed
with the minutes of the Corporation, duly adopted a resolution setting forth a
proposed amendment to the Certificate of Incorporation of the Corporation,
declaring said amendment to be advisable and calling for the sole stockholder of
the Corporation to consider its approval. The resolution proposed that the
Certificate of Incorporation be amended by deleting the existing Article FOURTH
and restating it in its entirety to read as follows:

          FOURTH: The total number of shares of capital stock which the
     Corporation shall have authority to issue is 150,000 shares of which
     147,000 shall be Common Stock with $1.00 par value per share, amounting in
     the aggregate to $147,000, and of which 3,000 shares shall be Preferred
     Stock with $1.00 par value per share, amounting in the aggregate to
     $3,000.

     PART A.   COMMON STOCK

          The following provisions of this PART A of this Article FOURTH
     constitute a statement of the powers, designations, limitations and
     restrictions of and relating to the Common Stock.

          1.   GENERAL. The Common Stock is junior to the Preferred Stock and is
     subject to and qualified by all the rights, powers, privileges, preferences
     and priorities of the Preferred Stock as set forth herein.

<Page>

                                       -2-

          2.   VOTING. The holders of the Common Stock are entitled to one vote
     for each share held at all meetings of stockholders (and written actions in
     lieu of meetings). There shall be no cumulative voting rights.

          3.   DIVIDENDS. Dividends may be declared and paid on the Common Stock
     from funds lawfully available therefore as and when determined by the Board
     of Directors and subject to any preferential dividend rights of any
     then-outstanding Preferred Stock.

          4.   LIQUIDATION. Upon the dissolution or liquidation of the
     Corporation, whether voluntary or involuntary, holders of Common Stock will
     be entitled to receive all assets of the Corporation available for
     distribution to its stockholders, ratably subject to any preferential
     rights of any then-outstanding Preferred Stock.

     PART B.   PREFERRED STOCK.

          The following provisions of this PART B of this Article FOURTH
     constitute a statement of the powers, designations, limitations and
     restrictions of and relating to the Preferred Stock.

          1.   DIVIDENDS. The holders of record of shares of the Preferred shall
     be entitled to receive cash dividends from funds lawfully available
     therefor, as and when declared by the Board of Directors. Such dividends
     shall be cumulative and payable at a per annum rate per share based on a
     360-day year equal to $2,050 per share multiplied by the LIBOR Rate (as
     defined below). For purposes hereof the LIBOR Rate shall be for each
     calendar year the 12-month LIBOR Rate for the first trading day of such
     year as published in a publication or issued by a financial institution
     selected in good faith by the Board of Directors of the Corporation. So
     long as any shares of the Preferred Stock are outstanding, the Corporation
     shall not declare, pay or set apart any dividend on the Common Stock or
     declare, make or set apart any distribution on the Common Stock unless
     concurrently therewith all accrued dividends or distributions on the
     Preferred Stock, through the date of such declaration, payment, making or
     setting apart of any dividend or distribution on the Common Stock, are
     declared, paid, made or set apart, as the case may be.

          2.   LIQUIDATION, DISSOLUTION OR WINDING UP.

               a.    In the event of any voluntary or involuntary liquidation,
     dissolution or winding up of the Corporation, the holders of shares of
     Preferred then outstanding shall be entitled to be paid out of the assets
     of the Corporation available for distribution to its stockholders, before
     any payment shall be made to the holders of Common Stock, an amount equal
     to $2,050 per share, plus the sum of all cumulated and accrued but
     undeclared and unpaid dividends thereon (subject to appropriate adjustment
     in the event of any stock dividend, stock split, combination or other
     similar recapitalization affecting such shares). If upon any such
     liquidation, dissolution or winding up of the Corporation the remaining
     assets of the Corporation available for distribution to its stockholders
     shall be insufficient to pay the holders of shares of Preferred Stock the
     full amount to which they

<Page>

                                       -3-

     shall be entitled, the holders of shares of Preferred Stock shall share
     ratably in any distribution of the remaining assets and funds of the
     Corporation in proportion to the respective amounts which would otherwise
     be payable in respect of the shares held by them upon such distribution if
     all amounts payable on or with respect to such shares were paid in full.

               b.    After the payment of all preferential amounts required to
     be paid to the holders of Preferred Stock, upon the dissolution,
     liquidation or winding up of the Corporation, the remaining assets and
     funds of the Corporation available for distribution to its stockholders
     shall be distributed to the holders of the Common Stock ratably in
     proportion to the respective amounts which would otherwise be payable in
     respect of the shares held by them.

               c.    Written notice or any liquidation, dissolution or winding
     up of the Corporation, setting forth a payment date, the amount of the
     payment to holders of Preferred Stock, and the place where said amount
     shall be payable shall be given not less than thirty (30) days prior to the
     payment date set forth therein, to each holder of record of the Preferred
     Stock.

               d.    Whenever the distribution provided in this subparagraph 2
     shall be payable in property other than cash, the value thereof shall be as
     determined in good faith by the Board of Directors of the Corporation.

          3.   VOTING

               The holders of the Preferred Stock shall have such voting
     rights as are required under the General Corporation Law of Delaware and
     shall be entitled to one vote for each share of Preferred Stock so held.
     There shall be no cumulative voting rights.

          4.   REDEMPTION AT THE OPTION OF THE HOLDERS.

               a.    REDEMPTION AND REDEMPTION PRICE. At any time and from time

     then outstanding and held by the holder requesting such redemption, at a

     Preferred Stock), together with an amount equal to the value of all
     cumulated and accrued but undeclared and unpaid dividends on such shares of
     Preferred Stock to which the holder thereof is entitled (any such dividend
     not payable in cash, being equal to the fair market value of such
     securities or other property as determined in good faith by the Board of
     Directors).

               b.    NOTICE OF REDEMPTION. Holders of shares of Preferred Stock
     who wish to have their shares redeemed pursuant to the preceding paragraph
     shall notify the Corporation in writing not less than thirty (30) nor more
     than sixty (60) calendar days prior

     holder of such share of Preferred Stock will cease, and such share of
     Preferred Stock shall no longer be deemed to be outstanding.

          5.   REDEMPTION AT THE OPTION OF THE COMPANY.

               a.    REDEMPTION CORPORATION AND REDEMPTION PRICE. At any time
     and from time to time upon the request of the Corporation to the holders of
     the Preferred Stock of Preferred Stock, the Corporation shall have the

     all or any part of the shares of Preferred Stock then outstanding, at a
     price of $2,050 per share (as appropriately adjusted for any stock
     dividend, stock split, subdivision, combination or reclassification of the
     Preferred Stock), together with an amount equal to the value of all
     cumulated and accrued but undeclared and unpaid dividends on such shares of
     Preferred Stock to which the holders thereof are entitled (any such
     dividend not payable in cash, being equal to the fair market value of such
     securities or other property as determined in good faith by the Board of
     Directors).

               b.    NOTICE OF REDEMPTION. In the event the Corporation wishes

     preceding paragraph, it shall notify all the holders of the Preferred Stock
     in writing not less than thirty (30) nor more than sixty (60) calendar days
