                                     - II -


     The undersigned applicants, each of whom has reached the age of twenty-one
years, wish to obtain letters patent under the provisions of Part I of the
CANADA CORPORATIONS ACT, constituting the applicants and other persons who may
become shareholders of the Company so created as a body corporate and politic
under the name of

                           RX INFORMATION CENTRE LTD.

     The undersigned have ascertained and ensured that the proposed corporate
name under which the application for incorporation is submitted is not
identified with nor similar to the name under which any other existent company,
corporation, association or firm does business in Canada or is incorporated
pursuant to the laws of Canada or of one of its provinces, or does not resemble
such a name to the point where it could be misleading, and is not a name
otherwise likely to raise objections for reasons of public order.


                                     - III -


     The incorporation of the proposed Company is requested for the following
purposes:

<Page>

       To engage in human resource planning and consulting in the fields of
       information technology, cybernetics, organization and procedures,
       administration and financial management, and standardization, adequacy
       and coordination of construction and equipment supply techniques for
       purposes of social investments and more particularly regarding
       pharmacists.

     The HEAD OFFICE of the proposed Company will be in Montreal, at 445
St-Laurent Boulevard, in the judicial district of Montreal, Province of Quebec.


                                     - IV -


     The authorized SHARE CAPITAL of the Company will consist of 200,000 common
shares with no par value and 300,000 preferred shares with a par value of $1.
The total consideration for which the common shares with no par value will be
issued shall not exceed the amount of $200,000 or any greater amount that the
Board of directors of the Company may determine and that has received the
approval of the Minister of Consumer and Corporate Affairs upon payment of the
required fees.

     The following privileges and restrictions are attached to the preferred
shares:


       A. - The holders of preferred shares shall be entitled to receive, on a
       priority basis over the holders of the Company's common shares, a fixed,
       preferred, non-cumulative dividend of six percent (6%) per year on the
       amount paid; such dividend shall be payable at the time and in the manner
       determined by the directors;

       B. - Upon dissolution or liquidation or any another distribution of
       property, the preferred shares shall have priority over the Company's
       common shares as to payment of capital and to dividends declared but
       remaining unpaid;

       C. - Holders of preferred shares shall not otherwise participate in the
       profits or excess assets of the Company;

       D. - The holders of preferred shares shall not as such be entitled to
       receive notice of meetings of shareholders or to attend or vote at such
       meetings, except regarding matters likely to affect the privileges,
       priorities and rights attached to said preferred shares and resolutions
       in connection with the liquidation of the Company;

            The right to receive notice of meetings of shareholders and to
       attend and vote at such meetings shall however be granted to holders of
       preferred shares, at a rate of one (1) vote per preferred share held,
       every time the Company fails to pay a dividend at the prescribed rate for
       two (2) consecutive years. Upon payment of a complete annual dividend,
       such voting right shall cease until a similar default occurs again;

<Page>

       E. - Subject to the provisions of Subsection (3) of Section 52 of the
       CANADA CORPORATIONS ACT, the preferred shares may be redeemed for
       cancellation out of capital upon a thirty-day written notice, at a price
       which shall include the amount paid as well as any declared dividends
       remaining unpaid. Any partial redemption shall be made pro rata to the
       number of preferred shares held by all the shareholders, excluding any
       fractions of shares. Redeemed preferred shares shall be cancelled and not
       reissued, and the share capital of the Company shall be reduced
       accordingly upon filing of the notice mentioned in Section 63 of the said
       Act;

       F. - Subject to the provisions of Section 62 of the CANADA CORPORATIONS
       ACT, the Company shall be entitled, at the discretion of its Board of
       directors, at any time, to purchase for cancellation all or part of the
       issued preferred shares, upon such shares being surrendered to the
       Company following a call for purchase addressed to all of the holders of
       preferred shares, at the lowest price at which, in the opinion of the
       directors, such shares can be obtained, but not exceeding the amount paid
       for such shares including all dividends declared and remaining unpaid.
       If, in response to a call for purchase, two (2) or more holders offer to
       render their shares at the same price and such offers are accepted by the
       Company, in whole or in part, then, unless the Company accepts all of
       such offers entirely, it shall accept the offers in parts as
       proportionate as possible to the number of shares included in each offer.
       The purchased preferred shares shall be retired as of the date of their
       purchase and shall not be reissued;

       G. - No issue of preferred shares ranking pari passu or prior to the
       above-mentioned preferred shares shall be authorized and the above
       provisions regarding the preferred shares shall not be amended, unless
       such issue or amendment shall have been approved by the vote of the
       holders of at least three quarters (3/4) in value of the preferred shares
       present at a special general meeting called for such purpose, in addition
       to the other formalities provided by the CANADA CORPORATIONS ACT.


                                      - V -


     The Company shall be incorporated as a "private company" with the following
restrictions:


       1. - No transfer of shares of the share capital of the Company shall be
       effected without the consent of its Board of directors given by way of
       resolution.

       2. - The number of the Company's shareholders shall be limited to fifty
       (50), not including persons who are in the employment of the Company and
       persons who, having been formerly in the employment of the Company, were,
       while in that employment, and have continued after the termination of
       that employment, to be shareholders of the Company,

<Page>

       two (2) or more persons holding one (1) or more shares jointly being
       counted as a single shareholder.

       3. - Any invitation to the public to subscribe for any shares or
       debentures of the Company is prohibited.


                                     - VI -


     In addition to the powers granted to the Company under Section 16 of the
CANADA CORPORATIONS ACT, the Company shall hold the following powers:


       (a)   The Company shall be entitled to pay a commission to any person in
       consideration for subscribing or agreeing to subscribe, absolutely or
       conditionally, for shares in the share capital of the Company, or
       obtaining or agreeing to obtain subscriptions, absolutely or
       conditionally, for shares of the Company, provided, however, that if such
       shares have a par value, such commission, whether it be in cash or
       shares, shall not exceed fifteen percent (15%) of the par value of such
       shares, and that if such shares have no par value, such commission shall
       not exceed, where it is in cash, fifteen percent (15%) of the
       consideration for which such shares are issued, and where it is in
       shares, fifteen percent (15%) of the number of shares then subscribed
       for.

       (b)   The directors of the Company may be relieved of their duties by way
       of resolution adopted by a simple majority at a special general meeting
       of shareholders duly called for such purpose.
