                             MEDICAL DATA BANC, INC.

        I, the undersigned, a natural person of the age of nineteen (19) years
or more, acting as incorporator under the Alaska Business Corporation Act,
adopts the following Articles of Incorporation for such corporation.



                                   ARTICLE ONE

        NAME:     The name of the corporation shall be:


                             MEDICAL DATA BANC, INC.

                                   ARTICLE TWO

        DURATION: This corporation shall commence at the time that a certificate
of incorporation shall be issued and shall continue thereafter without limit.


                                  ARTICLE THREE

        PURPOSES AND POWERS: The purposes for which the corporation is organized
are to sell and promote services and products relating to medical data.

        This corporation shall have the power, to such extent as a corporation
organized under the Alaska Business Corporation Act may now or hereafter
lawfully do, to do, either as principal or agent and either alone or in
connection with other corporations, firms, or individuals, all and








everything necessary, suitable, convenient, or proper for, or in connection
with, or incident to, the accomplishment of any of the purposes for the
attainment, of any one or more of the objects herein enumerated, or designed
directly or indirectly to promote the interests of this corporation or to
enhance the value of its properties; and in general to do any and all things and
exercise any and all powers, rights, and privileges which a corporation may now
or hereafter be organized to do or to exercise under the Alaska Business
Corporation Act or under any Act amendatory thereof, supplemental thereto, or
substituted therefor.

                                  ARTICLE FOUR

        CAPITALIZATION: The aggregate number of shares that the corporation
shall have authority to issue shall be Five Hundred (500) shares, all of such
shares being without par value.

                                  ARTICLE FIVE

        PRE-EMPTIVE RIGHTS: After each of the original stockholders shall have
reached parity concerning the number of shares they shall hold, each stockholder
of this corporation shall have the right to purchase shares of this corporation
that may from time to time be issued whether or not presently authorized,
including shares from the treasury of this corporation, in the ratio that the
number of shares the




                                       2




stockholder holds at the time of issue bears to the total number of shares
outstanding, exclusive of treasury shares. This right shall have been deemed
waived by any stockholder who does not exercise it and pay for the shares
pre-emptive within thirty (30) days of receipt of a notice in writing from the
corporation stating the prices, terms and conditions of the issue of shares and
inviting him to exercise his preemptive rights.

        Until each of the stockholders shall have reached parity, stockholders
of this corporation shall have no pre-emptive or preferential right of
subscription to any shares of this corporation, whether now or hereafter
authorized. The acceptance of shares in this corporation shall be a waiver of
any such pre-emptive or preferential right which, in the absence of this
provision, might otherwise be asserted by stockholders of this corporation, or
any of them.

                                   ARTICLE SIX

        LIMITATION ON TRANSFER OF STOCK: In case any stockholder of this
corporation should desire to sell, transfer, pledge, encumber, or in any manner
dispose of his shares of stock during his lifetime, he must offer for sale to
the corporation, in writing, the said share or shares of the corporation at the
same price and on the same terms as would govern upon a transfer to a person not
a stockholder.




                                       3




The corporation shall have ninety (90) days from the receipt of said offer
within which to exercise its option to purchase said stock. Said notice shall be
given by the stockholders to the company by a letter sent by United States
registered mail, addressed to the company at its registered office. The purchase
of such stock may be made by the company only out of earned surplus, but such
purchase may be made by action of the Board of Directors and without any action
of the stockholders of the corporation.

                (A)     In the event that the corporation should fail, refuse or
be unable to exercise, within ninety (90) days after receipt of the aforesaid
offer, its option to purchase all or a part of such stock, the remaining
stockholders of the corporation shall have the option to purchase said stock or
the portion thereof not purchased by the corporation, said option to be
exercised within sixty (60) days after there has been mailed to each stockholder
of the corporation a notice in writing giving the number of shares being offered
for sale and the price at which said shares are being offered. This notice shall
be sent by United States mail, addressed to each stockholder as shown by the
corporation's records, and shall be sent within five (5) days after the
expiration of the period granted the corporation within which to exercise its
prior option. Stockholders of the corporation, so desiring to purchase said
stock,





                                       4




shall send to the corporation, within the period aforesaid, written
subscriptions for the number of shares desired by them.

                (B)     If no part of the shares offered for sale, or if less
than the total number of shares so offered for sale, is purchased by the
corporation or stockholders, or both, then the stock not so purchased shall be
returned to the stockholders who offered the same for sale, and the said
stockholders shall thereafter have the right to sell said stock to whomsoever
will purchase same, provided, however, that the sale of such stock shall not be
made at any lower price than that which was offered to the corporation
originally, as aforesaid, and provided further that the sale of such stock shall
not be made later than one hundred eighty (180) days after the date upon which
said stock was offered to the corporation originally as aforesaid.

                If more than the total number of shares so offered for sale and
available for purchase by the stockholders of the corporation is desired by the
stockholders of the corporation, then the stockholders, so desiring to purchase
same, shall be entitled to purchase said stock in the proportions in which the
common stockholding of each stockholder purchasing the same bears to each other,
In the event that the proportion to which any stockholder should be entitled,
determined in this manner, should be more than the




                                       5




number of shares desired to be purchased by said stockholder, then the overplus
shall be distributed to the remaining stockholders, so desiring to purchase, in
the proportion in which the common stockholdings of such remaining stockholders
bear to each other. No fractional shares shall be issued in connection with any
offerings under this Article but only whole shares will be issued to the
stockholders. At the option of the corporation, (l) the sum total of the
fractional shares may be purchased by the corporation at the price at which the
stock was offered originally, provided that such purchase shall be made only out
of earned surplus, or (2) the sum total of the fractional shares may be returned
to the stockholder who offered the same for sale and the said stockholder shall
have the right to sell said stock to whomsoever will purchase the same provided,
however, the sale of such stock shall not be made at any lower price than that
which it was offered to the corporation originally, and provided further that
the sale of such stock shall not be made later than one hundred eighty (180)
days after the date upon which the said stock was offered to the corporation
originally, as aforesaid.

                (C)     All stock so purchased by the corporation under and
pursuant to the provisions of this Article shall be cancelled by the corporation
forthwith.

                (D)     No transfer of stock shall be binding




                                       6




upon the corporation unless made and recorded upon its stock books.

                (E)     A reference to this Article shall be printed on each
certificate of common stock issued by the corporation and the provisions of this
Article shall be binding upon every person now or hereafter becoming a
stockholder of this corporation, all of whom shall take such common stock
subject to the provisions hereof; and all pledges, hypothecations, or other
encumbrances of said stock, or dealing with regard thereto, shall likewise be
subject to the provisions hereof.

                (F)     Nothing contained herein shall prevent the stockholders
of this corporation from entering into an agreement for the sale and purchase of
stock as long as the terms of said agreement are not inconsistent herewith. In
this regard, any agreement which establishes the price at which a stockholder
must offer the stock to the corporation under this Article, or which provides
that said stock shall be offered at an established price to the corporation upon
termination of a stockholder's employment, or upon a stockholder's death, shall
not be deemed to be inconsistent herewith.
