Directors on February 11, 2000, in accordance with Section 302A.401 of the
Minnesota Business Corporation Act, duly adopted the following resolutions
establishing a series of the Corporation's capital stock, to be designated as
its Series B Preferred Stock:

     RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation by the Articles of Incorporation of the Corporation, the
Board of Directors hereby establishes the Series B Preferred Stock of the
Corporation and hereby states the designation and number of shares, and fixes
the relative rights and preferences, of such series of shares as follows:


Section 1: Authorized Shares.

     The shares of such series shall be designated the Series B Preferred Stock,
par value $.01 per share (the "Series B Preferred Stock") and the number of
shares constituting the Series B Preferred Stock shall be 3,000,000.

Section 2: Voting.

     (a) General. Holders of Series B Preferred Stock shall not be entitled to
vote on any matters submitted by the shareholders, except as otherwise required
by law.

Section 3 :  Liquidation.

     In the event of an involuntary or voluntary liquidation or dissolution of
the Corporation at any time, any remaining assets and surplus funds of the
Corporation shall be distributed pro rata to the holders of Series B Preferred
Stock and Common Stock, par value $.01 ("Common Stock").


Section 4:   Redemption of Series B Preferred Stock.

     (a) The Corporation shall have the right or the obligation to redeem any or
all of the shares of the Series B Preferred Stock on the terms and conditions
contained in this Section 4.

     (b) The Corporation shall have the option to redeem any or all of the
shares of Series B Preferred Stock at a redemption price equal to $.01 per share
in the event that Amira Medical, the purchaser of the Series B Preferred Stock
("Purchaser"), is in material breach of its obligations set forth in Section 2.1
of the Series B Preferred Stock Purchase Agreement, dated as of February 15,
2000 (the "Purchase Agreement") as provided in Section 11.1 of the Purchase
Agreement.

     (c) All shares of Series B Preferred Stock shall be subject to mandatory
redemption by the Corporation (or its successor-in-interest) at a redemption
price equal to the total price paid by Purchaser for the Series B Preferred
Stock plus a 10% premium in the event that: (x) the Corporation enters into an
agreement with any person, entity or group (other than the Purchaser and its
affiliates, agents and representatives) relating to any merger, consolidation,
sale of all or substantially all of the assets of the Corporation, sale of more
than 50% of the outstanding shares of Common Stock of the Corporation or other
transaction which results in such person, entity or group obtaining the right to
elect a majority of the Corporation's board of directors or otherwise to
exercise control over the Corporation (each an "Acquisition") and the
Corporation is not in breach of the April 2, 1999 Option Agreement between the
Corporation and the Purchaser (the "Option Agreement"), or (y) the Corporation
fails to exercise its option (the "Option") to merge (the "Merger") with and
into a newly formed, wholly owned subsidiary of Purchaser pursuant to the terms
of the Option Agreement on or before the expiration of the Option as set forth
in the Option Agreement. Any such redemption shall occur on the date of the
consummation of the Acquisition, in the case of an Acquisition or on the date
that is ninety (90) days after the expiration of the Option as set forth in the
Option Agreement.

     (d) All shares of Series B Preferred Stock shall be subject to mandatory
redemption by the Corporation (or its successor-in-interest) at a redemption
price equal to the total price paid by Purchaser for such shares of Series B
Preferred Stock plus a 10% premium in the event that the Corporation exercises
the Option and the shareholders of the Corporation do not approve the Merger at
a shareholders' meeting called for the purpose of approving such Merger in
accordance with the terms of the Option Agreement (including any adjournments of
such meeting which do not exceed one year in length).

     (e) The Corporation shall provide Purchaser with notice of any redemption,
at its principal offices, including the date upon which such shares will be
redeemed by the Corporation (the "Redemption Date") (which may be the date of
such notice in case of a redemption made pursuant to Section 4(b)).

     (f) On the Redemption Date, each holder shall surrender to the Corporation
the certificates representing the shares so redeemed, duly endorsed or assigned
to the Corporation, and the holder shall thereafter be entitled to receive
payment of the redemption price.

                                      -2-


     (g) On the Redemption Date, (i) such shares shall be deemed no longer
outstanding, and (ii) all rights of such holder as a holder of Series B
Preferred Stock (except the right to receive from the Corporation the monies
payable upon redemption upon surrender of the certificates evidencing such
shares) shall cease.

Section 5:  Conversion of the Series B Preferred Stock.

     The Series B Preferred Stock shall automatically be converted into shares
of Common Stock of the Corporation, without any act by the Corporation or the
holders of the Series B Preferred Stock, concurrently with the exercise of the
Option by the Corporation. Each holder of a share of Series B Preferred Stock so
converted shall be entitled to receive one share of Common Stock; provided,
however, that if the Corporation is then subject to Rule 4310 of the National
Association of Securities Dealers or any similar or successor rule of the
National Association of Securities Dealers, then in no event shall the aggregate
number of shares of Common Stock into which such shares of Series B Preferred
Stock be converted into exceed 1,935,996 shares of Common Stock of the
Corporation (the "Cap") and any shares of Series B Preferred Stock outstanding
in excess of Cap shall remain as Series B Preferred Stock. Upon such conversion,
each holder of a share of Series B Preferred Stock shall immediately surrender
such share in exchange for appropriate stock certificates representing a share
or shares of Common Stock of the Corporation and a stock certificate for Series
B Preferred in excess of the Cap.

     IN WITNESS WHEREOF, the undersigned, the Chief Executive Officer of Integ
Incorporated, being duly authorized on behalf of Integ Incorporated, has
executed this document as of February 15, 2000.
