                          OF SERIES A PREFERRED STOCK

                                      OF

                           VASCULAR SOLUTIONS, INC.


     The undersigned, being the Chief Executive Officer of Vascular Solutions,
Inc. (the "Corporation"), a corporation organized and existing under the
Minnesota Business Corporation Act, in accordance with the provisions of
Minnesota Statutes, Section 302A.401, Subd. 3(b), does hereby certify 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 on December 17, 1997, in accordance with Minnesota Statutes, Section
302A.401, Subd. 3, duly adopted the following resolution establishing a series
of Preferred Stock of the Corporation to be designated as its Series A Preferred
Stock.

     RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation (the "Board of Directors") by the Articles of Incorporation
of the Corporation, the Board of Directors hereby establishes the Series A
Preferred Stock of the Corporation as follows:

               RIGHTS, PREFERENCES, PRIVILEGES AND RESTRICTIONS
                          OF SERIES A PREFERRED STOCK

     The Preferred Stock authorized hereby shall be designated "Series A
                                                                --------
Preferred Stock" and shall consist of Two Million (2,000,000) shares. The
- ---------------
rights, preferences, privileges, and restrictions granted to and imposed on the
Series A Preferred Stock are as set forth below.

     1.   Dividend Provisions. The holders of shares of Series A Preferred Stock
          -------------------
shall be entitled to receive dividends, out of any assets legally available
therefor, prior and in preference to any declaration or payment of any dividend
(payable other than in Common Stock or other securities and rights convertible
into or entitling the holder thereof to receive, directly or indirectly,
additional shares of Common Stock of the Corporation) on the Common Stock of the
Corporation, at the rate of $0.20 per share per annum on each outstanding share
of Series A Preferred Stock, payable quarterly when, as and if declared by the
Board of Directors.  Such dividends shall not be cumulative.

     2.   Liquidation
          -----------

               (a)  Series A Preferred Stock.  In the event of any liquidation,
                    ------------------------
dissolution or winding up of the Corporation, either voluntary or involuntary,
the holders of the Series A Preferred Stock shall be entitled to receive, prior
and in preference to any distribution of any of the assets of the Corporation to
the holders of Common Stock by reason of their ownership thereof, an amount per
share equal to $2.50 per share for each share of Series A Preferred Stock then
held by them, plus declared but unpaid dividends. If, upon the occurrence of
such event, the assets and funds thus distributed among the holders of the
Series A Preferred Stock shall be insufficient to permit the payment to such
holders of the full aforesaid preferential amounts, then


the entire assets and funds of the Corporation legally available for
distribution shall be distributed ratably among the holders of the Series A
Preferred Stock in proportion to the preferential amount each such holder is
otherwise entitled to receive.

          (b)  Common Stock.  Upon the completion of the distribution required
               ------------
by Section 2(a) above, the remaining assets of the Corporation available for
distribution to shareholders shall be distributed among the holders of the
Common Stock pro rata based on the number of shares of Common Stock held by each
until the holders of the Common Stock shall have received an aggregate of (i)
$8,700,000 and (ii) an amount equal to the proceeds  to the Company from the
sale of Common Stock pursuant to the Confidential Private Placement Memorandum
dated December 8, 1997 (net of discounts, commissions and expenses).

          (c)  Remaining Assets.  Upon the completion of the distributions
               ----------------
required by Sections 2(a) and (b) above, the remaining assets of the Corporation
available for distribution to shareholders shall be distributed among the
holders of the Series A Preferred Stock and the Common Stock pro rata based on
the number of shares of Common Stock held by each (assuming conversion of all
such Series A Preferred Stock) until the holders of Series A Preferred Stock
shall have received an aggregate of $5.16 per share (including amounts paid
pursuant to Section 2(a) above); thereafter, if assets remain in the
Corporation, the holders of the Common Stock of this Corporation shall receive
all of the remaining assets pro rata based on the number of shares of Common
Stock held by each.

          (d)  Certain Acquisitions
               --------------------

                    (i)  Deemed Liquidation.  For purposes of this Section 2, a
                         ------------------
liquidation, dissolution or winding up of the Corporation shall be deemed to
occur if the Corporation shall sell, convey, or otherwise dispose of or encumber
all or substantially all of its property or business or merge into or
consolidate with any other Corporation (other than a wholly-owned subsidiary
Corporation) or effect any other transaction or series of related transactions
unless, after such sale, merger or other event, the shareholders of the
Corporation immediately prior to such event own a majority of the outstanding
shares of the surviving corporation or the corporation or other entity holding
such property or business.

                   (ii)  Valuation of Consideration.  In the event of a deemed
                         --------------------------
liquidation as described in Section 2(d)(i) above, if the consideration received
by the Corporation is other than cash, its value will be deemed to equal its
fair market value as reasonably determined in good faith by the Board of
Directors; provided, that any securities shall be valued as follows:

                         (A) Securities not subject to investment letter or
other similar restrictions on free marketability:

                             (1) If traded on a securities exchange or the
Nasdaq National Market, the value shall be deemed to be the average of the
closing prices of the securities on such exchange over the thirty-day period
ending three (3) days prior to the closing;

                             (2) If actively traded over-the-counter, the value
shall be deemed to be the average of the closing bid or sale prices (whichever
is applicable) over the thirty-day period ending three (3) days prior to the
closing; and

                                      -5-


                             (3) If there is no active public market, the value
shall be the fair market value thereof, as reasonably determined in good faith
by the Board of Directors.

                         (B) The method of valuation of securities subject to
investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a shareholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in Section 2(d)(ii)(A) to reflect the approximate fair
market value thereof, as reasonably determined in good faith by the Board of
Directors.

                  (iii)  Notice of Transaction.  The Corporation shall give each
                         ---------------------
holder of record of Series A Preferred Stock written notice of such impending
transaction not later than ten (10) days prior to the shareholders' meeting
called to approve such transaction, or ten (10) days prior to the closing of
such transaction, whichever is earlier, and shall also notify such holders in
writing of the final approval of such transaction.  The first of such notices
shall describe the material terms and conditions of the impending transaction
and the provisions of this Section 2, and the Corporation shall thereafter give
such holders prompt notice of any material changes.  The transaction shall in no
event take place sooner than ten (10) days after the Corporation has given the
first notice provided for herein or sooner than ten (10) days after the
Corporation has given notice of any material changes provided for herein;
provided, however, that such periods may be shortened upon the written consent
of the holders of Series A Preferred Stock that are entitled to such notice
rights and that represent at least a majority of the voting power of all the
outstanding shares of Series A Preferred Stock.

                  (iv)   Effect of Noncompliance.  In the event the requirements
                         -----------------------
of this Section 2(d) are not complied with, the Corporation shall forthwith
either cause the closing of the transaction to be postponed until such
requirements have been complied with, or cancel such transaction, in which event
the rights, preferences and privileges of the holders of the Series A Preferred
Stock shall revert to and be the same as such rights, preferences and privileges
existing immediately prior to the date of the first notice referred to in
Section 2(d)(iii) hereof.

     3.   Redemption
          ----------

               (a) At any time after December 19, 2002, but within thirty (30)
days (the "Redemption Date") after the receipt by this Corporation of a written
           ---------------
request from the holders of not less than a majority of the then outstanding
Series A Preferred Stock that all or some of such holders' shares be redeemed,
and concurrently with surrender by such holders of the certificates representing
such shares, this Corporation shall, to the extent it may lawfully do so, redeem
the shares specified in such request by paying in cash therefor a sum per share
equal to $2.50 per share of Series A Preferred Stock (as adjusted for any stock
dividends, combinations or splits with respect to such shares) plus all declared
but unpaid dividends on such shares (the " Redemption Price"). Any redemption
                                           ----------------
effected pursuant to this Section 3(a) shall be made on a pro rata basis among
the holders of the Series A Preferred Stock delivering such notice in proportion
to the number of shares of Series A Preferred Stock then held by such holders.

               (b) At least fifteen (15) but no more than thirty (30) days prior
to each Redemption Date, written notice shall be mailed, first class postage
prepaid, to each holder of record (at the close of business on the business day
next preceding the day on which notice is given) of the Series A Preferred Stock
to be redeemed, at the address last shown on the records of this

                                      -6-


Corporation for such holder, notifying such holder of the redemption to be
effected, specifying the number of shares to be redeemed from such holder, the
Redemption Date, the Redemption Price, the place at which payment may be
obtained and calling upon such holder to surrender to this Corporation, in the
manner and at the place designated, his, her or its certificate or certificates
representing the shares to be redeemed (the "Redemption Notice"). Except as
                                             -----------------
provided in subsection (3)(c) on or after the Redemption Date, each holder of
Series A Preferred Stock to be redeemed shall surrender to this Corporation the
certificate or certificates representing such shares, in the manner and at the
place designated in the Redemption Notice, and thereupon the Redemption Price of
such shares shall be payable to the order of the person whose name appears on
such certificate or certificates as the owner thereof and each surrendered
certificate shall be canceled. In the event less than all the shares represented
by any such certificate are redeemed, a new certificate shall be issued
representing the unredeemed shares.

               (c) From and after the Redemption Date, unless there shall have
been a default in payment of the Redemption Price, all rights of the holders of
shares of Series A Preferred Stock designated for redemption in the Redemption
Notice as holders of Series A Preferred Stock (except the right to receive the
Redemption Price without interest upon surrender of their certificate or
certificates) shall cease with respect to such shares, and such shares shall not
thereafter be transferred on the books of this Corporation or be deemed to be
outstanding for any purpose whatsoever.  Subject to the rights of series of
Preferred Stock which may from time to time come into existence, if the funds of
the Corporation legally available for redemption of shares of Series A Preferred
Stock on any Redemption Date are insufficient to redeem the total number of
shares of Series A Preferred Stock to be redeemed on such date, those funds
which are legally available will be used to redeem the maximum possible number
of such shares ratably among the holders of such shares to be redeemed based
upon their holdings of Series A Preferred Stock.  The shares of Series A
Preferred Stock not redeemed shall remain outstanding and entitled to all the
rights and preferences provided herein.  Subject to the rights of series of
Preferred Stock which may from time to time come into existence, at any time
thereafter when additional funds of the Corporation are legally available for
the redemption of shares of Series A Preferred Stock, such funds will
immediately be used to redeem the balance of the shares which the Corporation
has become obliged to redeem on any Redemption Date but which it has not
redeemed.

               (d) On or prior to each Redemption Date, this Corporation shall
deposit the Redemption Price of all shares of Series A Preferred Stock
designated for redemption in the Redemption Notice, and not yet redeemed or
converted, with a bank or trust corporation having aggregate capital and surplus
in excess of $100,000,000 as a trust fund for the benefit of the respective
holders of the shares designated for redemption and not yet redeemed, with
irrevocable instructions and authority to the bank or trust corporation to
publish the notice of redemption thereof and pay the Redemption Price for such
shares to their respective holders on or after the Redemption Date, upon receipt
of notification from the Corporation that such holder has surrendered his, her
or its share certificate to the Corporation pursuant to Section (3)(b) above. As
of the date of such deposit (even if prior to the Redemption Date), the deposit
shall constitute full payment of the shares to their holders, and from and after
the date of the deposit the shares so called for redemption shall be redeemed
and shall be deemed to be no longer outstanding, and the holders thereof shall
cease to be shareholders with respect to such shares and shall have no rights
with respect thereto except the rights to receive from the bank or trust

                                      -7-


corporation payment of the Redemption Price of the shares, without interest,
upon surrender of their certificates therefor, and the right to convert such
shares as provided in Section 4.  Such instructions shall also provide that any
moneys deposited by the Corporation pursuant to this Section (3)(d) for the
redemption of shares thereafter converted into shares of the Corporation's
Common Stock pursuant to Section 4 hereof prior to the Redemption Date shall be
returned to the Corporation forthwith upon such conversion.  The balance of any
moneys deposited by this Corporation pursuant to this Section (3)(d) remaining
unclaimed at the expiration of two (2) years following the Redemption Date shall
thereafter be returned to this Corporation upon its request expressed in a
resolution of its Board of Directors.

     4.  Conversion.  The holders of the Series A Preferred Stock shall have
         ----------
conversion rights as follows (the "Conversion Rights"):
                                   -----------------

               (a) Right to Convert.  Subject to Section 4(c), each share of
                   ----------------
Series A Preferred Stock shall be convertible, at the option of the holder
thereof, at any time after the date of issuance of such share, at the office of
the Corporation or any transfer agent for such stock, into such number of fully
paid and nonassessable shares of Common Stock as is determined by dividing $2.50
by the Conversion Price applicable to such share, determined as hereafter
provided (the "Conversion Price"), in effect on the date the certificate is
surrendered for conversion. The initial Conversion Price per share of Series A
Preferred Stock shall be $2.50. Such initial Conversion Price shall be subject
to adjustment as set forth in Section 4(d). Notwithstanding the foregoing, if a
holder of Series A Preferred Stock does not elect to convert pursuant to this
Section 4(a) prior to any distribution of any of the assets of the Corporation
pursuant to Section 2(a), then such holder of Series A Preferred Stock shall not
be entitled to convert pursuant to this Section 4(a) until after any
distribution of any of the assets of the Corporation required pursuant to
Section 2(b) is completed.

               (b) Automatic Conversion.  Each share of Series A Preferred Stock
                   --------------------
shall automatically be converted into shares of Common Stock at the Conversion
Price at the time in effect for such share, except as provided below in Section
4(c), immediately upon the Corporation's sale of its Common Stock in a firm
commitment underwritten public offering pursuant to a registration statement
under the Securities Act of 1933, as amended (the "Securities Act"), the public
                                                   --------------
offering price of which is not less than $8.50 per share (as adjusted to reflect
subsequent stock dividends, stock splits or recapitalizations occurring after
the date of issuance of the Series A Preferred Stock and prior to the closing of
such public offering) and which results in an aggregate public offering price of
at least $20,000,000.

               (c) Mechanics of Conversion.  Before any holder of Series A
                   -----------------------
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, he shall surrender the certificate or certificates therefor, duly
endorsed, at the office of the Corporation or of any transfer agent for the
Series A Preferred Stock, and shall give written notice to the Corporation at
its principal corporate office, of the election to convert the same and shall
state therein the name or names in which the certificate or certificates for
shares of Common Stock are to be issued. The Corporation shall, as soon as
practicable thereafter, issue and deliver at such office to such holder of
Series A Preferred Stock, or to the nominee or nominees of such holder, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid. Such conversion shall be deemed to
have been made immediately prior to the close of

                                      -8-


business on the date of such surrender of the shares of such Series A Preferred
Stock to be converted, and the person or persons entitled to receive the shares
of Common Stock issuable upon such conversion shall be treated for all purposes
as the record holder or holders of such shares of Common Stock as of such date.
If the conversion is in connection with an underwritten offering of securities
registered pursuant to the Securities Act the conversion may, at the option of
any holder tendering such shares of Series A Preferred Stock for conversion, be
conditioned upon the closing with the underwriters of the sale of securities
pursuant to such offering, in which event the person(s) entitled to receive
Common Stock upon conversion of such Series A Preferred Stock shall not be
deemed to have converted such Series A Preferred Stock until immediately prior
to the closing of such sale of securities.

               (d) Conversion Price Adjustments of Series A Preferred Stock for
                   ------------------------------------------------------------
Certain Dilutive Issuances, Splits and Combinations.  The Conversion Price of
- ---------------------------------------------------
the Series A Preferred Stock shall be subject to adjustment from time to time as
follows:

                       (i) Issuance of Additional Stock below Purchase Price. If
                           -------------------------------------------------
the Corporation shall issue, after the date upon which the shares of Series A
Preferred Stock were first issued (the "Purchase Date"), any Additional Stock
                                        -------------
(as defined below) without consideration or for a consideration per share less
than the Conversion Price for such series in effect immediately prior to the
issuance of such Additional Stock, the Conversion Price for such series in
effect immediately prior to each such issuance shall automatically be adjusted
as set forth in this Section 4(d)(i), unless otherwise provided in this Section
4(d)(i).

                           (A) Adjustment Formula.  Whenever the Conversion
                               ------------------
Price is adjusted pursuant to this Section 4(d)(i), the new Conversion Price
shall be a price equal to the quotient obtained by dividing the total computed
under clause (x) below by the total computed under clause (y) below as follows:

                               (x)  an amount equal to the sum of

                                    (1) the aggregate purchase price of the
shares of Series A Preferred Stock issued on the Purchase Date (the "Series A
                                                                     --------
Purchase Price") (i.e., $5,000,000), plus
- --------------

                                    (2) the aggregate consideration, if any,
received by the Corporation for all Additional Stock issued on or after the
Purchase Date;

                               (y)  an amount equal to the sum of:

                                    (1) the Series A Purchase Price for such
series divided by the initial Conversion Price (or such higher or lower
Conversion Price as results from the application of Sections 4(d)(ii) and (iii)
hereof), plus

                                    (2) the number of shares of Additional Stock
issued on or after the Purchase Date (as adjusted pursuant to Sections 4(d)(ii)
and (iii) hereof, if applicable).

                           (B) Definition of "Additional Stock".  For purposes
                               --------------------------------
of this Section 4(d)(i), "Additional Stock" shall mean any shares of Common
                          ----------------

issued to employees, consultants or directors of the Corporation directly or
pursuant to a stock option plan, stock purchase plan or other stock plan

                           (C) No Fractional Adjustments.  No adjustment of the
                               -------------------------
Conversion Price for the Series A Preferred Stock shall be made in an amount
less than one cent per share, provided that any adjustments which are not
required to be made by reason of this sentence shall be carried forward and
shall be either taken into account in any subsequent adjustment made prior to
three years from the date of the event giving rise to the adjustment being
carried forward, or shall be made at the end of three years from the date of the
event giving rise to the adjustment being carried forward.

                           (D) Determination of Consideration.  In the case of
                               ------------------------------
the issuance of Common Stock for cash, the consideration shall be deemed to be
the amount of cash paid therefor before deducting any reasonable discounts,
commissions or other expenses allowed, paid or incurred by the Corporation for
any underwriting or otherwise in connection with the issuance and sale thereof.
In the case of the issuance of the Common Stock for a consideration in whole or
in part other than cash, the consideration other than cash shall be deemed to be
the fair value thereof as determined by the Board of Directors irrespective of
any accounting treatment.

                           (E) Deemed Issuances of Common Stock.  In the case of

the issuance (whether before, on or after the applicable Purchase Date) of
options to purchase or rights to subscribe for Common Stock, securities by their
terms convertible into or exchangeable for Common Stock or options to purchase

                                      -10-


exchangeable securities, the following provisions shall apply for all purposes
of this Section 4(d)(i):

                               (1) The aggregate maximum number of shares of
Common Stock deliverable upon exercise (assuming the satisfaction of any
conditions to exercisability, including without limitation, the passage of time,
but without taking into account potential antidilution adjustments) of such
options to purchase or rights to subscribe for Common Stock shall be deemed to
have been issued at the time such options or rights were issued and for a
consideration equal to the consideration (determined in the manner provided in
Section 4(d)(i)(D)), if any, received by the Corporation upon the issuance of
such options or rights plus the minimum exercise price provided in such options
or rights (without taking into account potential antidilution adjustments) for
the Common Stock covered thereby.

                               (2) The aggregate maximum number of shares of
Common Stock deliverable upon conversion of or in exchange (assuming the
satisfaction of any conditions to convertibility or exchangeability, including,
without limitation, the passage of time, but without taking into account
potential antidilution adjustments) for any such convertible or exchangeable
securities or upon the exercise of options to purchase or rights to subscribe
for such convertible or exchangeable securities and subsequent conversion or
exchange thereof shall be deemed to have been issued at the time such securities
were issued or such options or rights were issued and for a consideration equal
to the consideration, if any, received by the Corporation for any such
securities and related options or rights (excluding any cash received on account
of accrued interest or accrued dividends), plus the minimum additional
consideration, if any, to be received by the Corporation (without taking into
account potential antidilution adjustments) upon the conversion or exchange of
such securities or the exercise of any related options or rights (the
consideration in each case to be determined in the manner provided in Section
4(d)(i)(D).

                               (3) In the event of any change in the number of
shares of Common Stock deliverable or in the consideration payable to the
Corporation upon exercise of such options or rights or upon conversion of or in
exchange for such convertible or exchangeable securities, including, but not
limited to, a change resulting from the antidilution provisions thereof, the
Conversion Price of the Series A Preferred Stock, to the extent in any way
affected by or computed using such options, rights or securities, shall be
recomputed to reflect such change, but no further adjustment shall be made for
the actual issuance of Common Stock or any payment of such consideration upon
the exercise of any such options or rights or the conversion or exchange of such
securities.

                               (4) Upon the expiration of any such options or
rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price of the Series A Preferred Stock, to the extent
in any way affected by or computed using such options, rights or securities or
options or rights related to such securities, shall be recomputed to reflect the
issuance of only the number of shares of Common Stock (and convertible or
exchangeable securities which remain in effect) actually issued upon the
exercise of such options or rights, upon the conversion or exchange of such
securities or upon the exercise of the options or rights related to such
securities.

                                      -11-


                               (5) The number of shares of Common Stock deemed
issued and the consideration deemed paid therefor pursuant to Sections
4(d)(i)(E)(1) and 4(d)(i)(E)(2) shall be appropriately adjusted to reflect any
change, termination or expiration of the type described in either Section
4(d)(i)(E)(3) or 4(d)(i)(E)(4).

                         (F) No Increased Conversion Price.  Notwithstanding any
                             -----------------------------
other provisions of this Section (4)(d)(i), except to the limited extent
provided for in Sections 4(d)(i)(E)(3) and 4(d)(i)(E)(4), no adjustment of the
Conversion Price pursuant to this Section 4(d)(i) shall have the effect of
increasing the Conversion Price above the Conversion Price in effect immediately
prior to such adjustment.

                    (ii) Stock Splits and Dividends.  In the event the
                         --------------------------
Corporation should at any time or from time to time after the Purchase Date fix
a record date for the effectuation of a split or subdivision of the outstanding
shares of Common Stock or the determination of holders of Common Stock entitled
to receive a dividend or other distribution payable in additional shares of
Common Stock or other securities or rights convertible into, or entitling the
holder thereof to receive directly or indirectly, additional shares of Common
Stock (hereinafter referred to as "Common Stock Equivalents") without payment of
                                   ------------------------
any consideration by such holder for the additional shares of Common Stock or
the Common Stock Equivalents (including the additional shares of Common Stock
issuable upon conversion or exercise thereof), then, as of such record date (or
the date of such dividend distribution, split or subdivision if no record date
is fixed), the Conversion Price of the Series A Preferred Stock shall be
appropriately decreased so that the number of shares of Common Stock issuable on
conversion of each share of such Series shall be increased in proportion to such
increase of the aggregate of shares of Common Stock outstanding and those
issuable with respect to such Common Stock Equivalents with the number of shares
issuable with respect to Common Stock Equivalents determined from time to time
in the manner provided for deemed issuances in Section 4(d)(i)(E).

                   (iii) Reverse Stock Splits. If the number of shares of Common
                         --------------------
Stock outstanding at any time after the Purchase Date is decreased by a
combination of the outstanding shares of Common Stock, then, following the
record date of such combination, the Conversion Price for the Series A Preferred
Stock shall be appropriately increased so that the number of shares of Common
Stock issuable on conversion of each share of such Series shall be decreased in
proportion to such decrease in outstanding shares.

               (e) Other Distributions.  In the event the Corporation shall
                   -------------------
declare a distribution payable in securities of other persons, evidences of
indebtedness issued by the Corporation or other persons, assets (excluding cash
dividends) or options or rights not referred to in Section 4(d)(ii), then, in
each such case for the purpose of this Section 4(e), the holders of Series A
Preferred Stock shall be entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of Common
Stock of the Corporation into which their shares of Series A Preferred Stock are
convertible as of the record date fixed for the determination of the holders of
Common Stock of the Corporation entitled to receive such distribution.

               (f) Recapitalizations. If at any time or from time to time there
                   -----------------
shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 4 or Section 2) provision shall be made

                                      -12-


so that the holders of the Series A Preferred Stock shall thereafter be entitled
to receive upon conversion of the Series A Preferred Stock the number of shares
of stock or other securities or property of the Corporation or otherwise, to
which a holder of Common Stock deliverable upon conversion would have been
entitled on such recapitalization. In any such case, appropriate adjustment
shall be made in the application of the provisions of this Section 4 with
respect to the rights of the holders of the Series A Preferred Stock after the
recapitalization to the end that the provisions of this Section 4 (including
adjustment of the Conversion Price then in effect and the number of shares
purchasable upon conversion of the Series A Preferred Stock) shall be applicable
after that event and be as nearly equivalent as practicable.

               (g) No Impairment.  The Corporation will not, by amendment of its
                   -------------
Articles of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 4 and in the taking of all such action as may
be necessary or appropriate in order to protect the Conversion Rights of the
holders of Series A Preferred Stock against impairment.

               (h) No Fractional Shares and Certificate as to Adjustments
                   ------------------------------------------------------

                         (i)  No fractional shares shall be issued upon the
conversion of any share or shares of the Series A Preferred Stock, and the
number of shares of Common Stock to be issued shall be rounded to the nearest
whole share. The number of shares issuable upon such conversion shall be
determined on the basis of the total number of shares of Series A Preferred
Stock the holder is at the time converting into Common Stock and the number of
shares of Common Stock issuable upon such aggregate conversion.

                         (ii) Upon the occurrence of each adjustment or
readjustment of the Conversion Price of Series A Preferred Stock pursuant to
this Section 4, the Corporation, at its expense, shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and prepare and
furnish to each holder of such Preferred Stock a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based. The Corporation shall, upon the written
request at any time of any holder of Series A Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (A) such
adjustment and readjustment, (B) the Conversion Price for the Series A Preferred
Stock at the time in effect, and (C) the number of shares of Common Stock and
the amount, if any, of other property which at the time would be received upon
the conversion of a share of the Series A Preferred Stock.

               (i) Notices of Record Date.  In the event of any taking by the
                   ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series A Preferred Stock, at least ten (10) days
prior to the date specified therein, a notice specifying the date on which any
such record is to be taken for the purpose of such dividend, distribution or
right, and the amount and character of such dividend, distribution or right.

                                      -13-


               (j) Reservation of Stock Issuable Upon Conversion.  The
                   ---------------------------------------------
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series A Preferred Stock, such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of Series A Preferred Stock; and if at any
time the number of authorized but unissued shares of Common Stock shall not be
sufficient to effect the conversion of all then outstanding shares of Series A
Preferred Stock, in addition to such other remedies as shall be available to the
holders of Series A Preferred Stock, the Corporation will take such corporate
action as may, in the opinion of its counsel, be necessary to increase its
authorized but unissued shares of Common Stock to such number of shares as shall
be sufficient for such purposes, including, without limitation, engaging in best
efforts to obtain the requisite shareholder approval of any necessary amendment
to the Articles of Incorporation.

               (k) Notices.  Any notice required by the provisions of this
                   -------
Section 4 to be given to the holders of shares of Series A Preferred Stock shall
be deemed given if deposited in the United States mail, postage prepaid, and
addressed to each holder of record at his address appearing on the books of the
Corporation.

     5.  Voting Rights.  The holder of each share of Series A Preferred Stock
         -------------
shall have the right to one vote for each share of Common Stock into which the
Series A Preferred Stock could then be converted, and with respect to such vote,
such holder shall have full voting rights and powers equal to the voting rights
and powers of the holders of Common Stock, and shall be entitled,
notwithstanding any provision hereof, to notice of any shareholders' meeting in
accordance with the bylaws of the Corporation, and shall be entitled to vote,
together with holders of Common Stock, with respect to any question upon which
holders of Common Stock have the right to vote. Fractional votes shall not,
however, be permitted and any fractional voting rights available on an as-
converted basis (after aggregating all shares into which shares of Series A
Preferred Stock held by each holder could be converted) shall be rounded to the
nearest whole number (with one-half being rounded upward).

     6.  Protective Provisions.  So long as any shares of Series A Preferred
         ---------------------
Stock are outstanding, the Corporation shall not without first obtaining the
approval (by vote or written consent, as provided by law) of the holders of at
least two-thirds of the then outstanding shares of Series A Preferred Stock,
voting together as a class:

               (a) effect a transaction described in Section 2(d)(i) above;

               (b) alter or change the rights, preferences or privileges of the
shares of Series A Preferred Stock so as to affect adversely the shares of such
series;

               (c) amend the Corporation's Articles of Incorporation or Bylaws
or change the authorized number of directors of the Corporation;

               (d) authorize or issue, or obligate itself to issue, any other
equity security, including any other security convertible into or exercisable
for any equity security, having a preference over, or being on a parity with,
the Series A Preferred Stock with respect to preference, redemption or
dividends;

                                      -14-


               (e) issue, or obligate itself to issue, any equity security, or
any security convertible into or exercisable for any equity security, if, after
such issuance, the Company would have outstanding more than 9,400,000 equity
securities (assuming for this purpose the issuance of all securities reserved
for issuance under stock option plans, stock purchase plans and other stock
plans approved by the Board of Directors of the Company, and exercise of all
then outstanding rights to acquire equity securities).

               (f) redeem, purchase or otherwise acquire (or pay into or set
funds aside for a sinking fund for such purpose) any share or shares of
Preferred Stock or Common Stock; provided, however, that this restriction shall
                                 --------  -------
not apply to the redemption of Series A Preferred Stock pursuant to Article 3
hereof; or

               (g) declare or pay any dividends or other distributions on
outstanding capital stock of the Corporation.

     7.  Status of Redeemed or Converted Stock.  In the event any shares of
         -------------------------------------
Series A Preferred Stock shall be redeemed pursuant to Section 3 hereof or
converted pursuant to Section 4 hereof, the shares so redeemed or converted
shall be canceled and shall not be issuable by the Corporation. Upon redemption
pursuant to Section 3 hereof or conversion pursuant to Section 4 hereof of all
outstanding shares of Series A Preferred Stock, all provisions of this
Certificate of Designation shall cease to be of further effect. Upon the
occurrence of such event, the Board of Directors shall have the power, pursuant
to Minnesota Statutes, Section 302A.135, Subd. 5 or any successor provision and
without shareholder action, to cause restated articles of incorporation of the
Corporation or other appropriate documents to be prepared and filed with the
Secretary of State of the State of Minnesota which reflect the removal of all
provisions relating to the Series A Preferred Stock and the cancellation of this
Certificate of Designation.

     8.  Par Value; No Cumulative Voting; No Preemptive Rights.  The Series A
         -----------------------------------------------------
Preferred Stock shall have a par value of $0.01 per share.  Holders of Series A
Preferred Stock shall not be entitled to cumulate their votes in any election of
directors in which they are entitled to vote and shall not be entitled to any
preemptive rights under the Corporation's Articles of Incorporation to acquire
shares of any class of series of capital stock of the Corporation.

                                      -15-

                           VASCULAR SOLUTIONS, INC.


     The undersigned, being the Chief Executive Officer of Vascular Solutions,
Inc. (the "Corporation"), a corporation organized and existing under the
Minnesota Business Corporation Act, in accordance with the provisions of
Minnesota Statutes, Section 302A.401, Subd. 3(b), does hereby certify 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 on December 8, 1998, in accordance with Minnesota Statutes, Section
302A.401, Subd. 3, duly adopted the following resolution establishing a series
of Preferred Stock of the Corporation to be designated as its Series B Preferred
Stock.

     RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation (the "Board of Directors") by the Articles of Incorporation
of the Corporation, the Board of Directors hereby establishes the Series B
Preferred Stock of the Corporation as follows:

                RIGHTS, PREFERENCES, PRIVILEGES AND RESTRICTIONS
                          OF SERIES B PREFERRED STOCK

     The Preferred Stock authorized hereby shall be designated "Series B
                                                                --------
Preferred Stock" and shall consist of One Million Seven Hundred and Seventy-
- ---------------
Seven Thousand Seven Hundred Seventy-Seven (1,777,777) shares.  The rights,
preferences, privileges, and restrictions granted to and imposed on the Series B
Preferred Stock are as set forth below.

     1.   Dividend Provisions.  The holders of shares of Series B Preferred
          -------------------
Stock shall be entitled to receive dividends, out of any assets legally
available therefor, prior and in preference to any declaration or payment of any
dividend (payable other than in Common Stock or other securities and rights
convertible into or entitling the holder thereof to receive, directly or
indirectly, additional shares of Common Stock of the Corporation) on the Series
A Preferred Stock or the Common Stock of the Corporation, at the rate of $0.36
per share per annum on each outstanding share of Series B Preferred Stock,
payable quarterly, when, as and if declared by the Board of Directors in its
sole and absolute discretion. Such dividends shall be cumulative, shall be paid
upon a liquidation, dissolution or winding-up of the Corporation as set forth in
Section 2 hereof and shall expire upon conversion of the Series B Preferred
Stock as set forth in Section 4 hereof.

     2.   Liquidation
          -----------

                                      -17-


          (a)  Series B Preferred Stock.  In the event of any liquidation,
               ------------------------
dissolution or winding up of the Corporation, either voluntary or involuntary,
the holders of the Series B Preferred Stock shall be entitled to receive, prior
and in preference to any distribution of any of the assets of the Corporation to
the holders of the Series A Preferred Stock or the Common Stock by reason of
their ownership thereof, an amount per share equal to $4.50 per share for each
share of Series B Preferred Stock then held by them, plus unpaid dividends due
thereon (the "Series B Liquidation Preference").  If, upon the occurrence of
such event, the assets and funds thus distributed among the holders of the
Series B Preferred Stock shall be insufficient to permit the payment to such
holders of the full Series B Liquidation Preference on each share held by them,
then the entire assets and funds of the Corporation legally available for
distribution shall be distributed ratably among the holders of the Series B
Preferred Stock in proportion to the preferential amount each such holder is
otherwise entitled to receive.

          (b)  Series A Preferred Stock. Upon the completion of the distribution
               ------------------------
required by Section 2(a) above, the holders of the Series A Preferred Stock
shall be entitled to receive, prior and in preference to any distribution of any
of the remaining assets of the Corporation to the holders of the Series B
Preferred Stock or Common Stock by reason of their ownership thereof, the
amounts described in Section 2(a) of the Certificate of Designation of Series A
Preferred Stock of the Corporation (the "Series A Certificate") as in effect on
the date hereof.

          (c)  Common Stock.  Upon the completion of the distributions required
               ------------
by Sections 2(a) and (b)  above, the holders of the Common Stock shall be
entitled to receive, prior and in preference to any distribution of any of the
remaining assets of the Corporation to the holders of the Series B Preferred
Stock by reason of their ownership thereof, the amounts described in Section
2(b) of the Series A Certificate as in effect on the date hereof.

          (d)  Remaining Assets.  Upon the completion of the distributions
               ----------------
required by Sections 2(a), (b) and (c) above, the remaining assets of the
Corporation available for distribution to shareholders shall be distributed
among the holders of the Series B Preferred Stock, the Series A Preferred Stock
and the Common Stock pro rata based on the number of shares of Common Stock held
by each (assuming conversion of all such Series A Preferred Stock and Series B
Preferred Stock) until the holders of Series A Preferred Stock shall have
received an aggregate of $5.16 per share (including amounts paid pursuant to
Section 2(b) above and this Section 2(d)); thereafter, the remaining assets of
the Corporation available for distribution to shareholders shall be distributed
among the holders of the Series B Preferred Stock and the Common Stock pro rata
based on the number of shares of Common Stock held by each (assuming conversion
of all such Series B Preferred Stock) until the holders of Series B Preferred
Stock shall have received an aggregate of $9.00 per share (including amounts
paid pursuant to Section 2(a) above and this Section 2(d)); thereafter, if
assets remain in the Corporation, the holders of the Common Stock of this
Corporation shall receive all of the remaining assets pro rata based on the
number of shares of Common Stock held by each.

          (e)  Certain Acquisitions
               --------------------

                                      -18-


              (i)   Deemed Liquidation.  For purposes of this Section 2, a
                    ------------------
liquidation, dissolution or winding up of the Corporation shall be deemed to
occur if the Corporation shall sell, convey, or otherwise dispose of or encumber
all or substantially all of its property or business or merge into or
consolidate with any other corporation (other than a wholly-owned subsidiary
corporation) or effect any other transaction or series of related transactions
unless, after such sale, merger or other event, the shareholders of the
Corporation immediately prior to such event own a majority of the outstanding
shares of the surviving corporation or the corporation or other entity holding
such property or business.

              (ii)  Valuation of Consideration.  In the event of a deemed
                    --------------------------
liquidation as described in Section 2(e)(i) above, if the consideration received
by the Corporation is other than cash, its value will be deemed to equal its
fair market value as reasonably determined in good faith by the Board of
Directors; provided, that any securities shall be valued as follows:

                    (A)  Securities not subject to investment letter or other
similar restrictions on free marketability:

                         (1)  If traded on a securities exchange or the Nasdaq
National Market, the value shall be deemed to be the average of the closing
prices of the securities on such exchange over the thirty-day period ending
three (3) days prior to the closing;

                         (2)  If actively traded over-the-counter, the value
shall be deemed to be the average of the closing bid or sale prices (whichever
is applicable) over the thirty-day period ending three (3) days prior to the
closing; and

                         (3)  If there is no active public market, the value
shall be the fair market value thereof, as reasonably determined in good faith
by the Board of Directors.

                    (B)  The method of valuation of securities subject to
investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a shareholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in Section 2(e)(ii)(A) to reflect the approximate fair
market value thereof, as reasonably determined in good faith by the Board of
Directors.

              (iii) Notice of Transaction.  The Corporation shall give each
                    ---------------------
holder of record of Series B Preferred Stock written notice of such impending
transaction not later than fourteen (14) days prior to the shareholders' meeting
called to approve such transaction, or fourteen (14) days prior to the closing
of such transaction, whichever is earlier, and shall also notify such holders in
writing of the final approval of such transaction.  The first of such notices
shall describe the material terms and conditions of the impending transaction
and the provisions of this Section 2, and the Corporation shall thereafter give
such holders prompt notice of any material changes.  The transaction shall in no
event take place sooner than fourteen (14) days after the Corporation has given
the first notice provided for herein or sooner than fourteen (14) days after the
Corporation has given notice of any material changes provided for herein;
provided, however, that such periods may be shortened upon the written consent
of the holders of

                                      -19-


Series B Preferred Stock that are entitled to such notice rights and that
represent at least a majority of the voting power of all the outstanding shares
of Series B Preferred Stock.

              (iv)  Effect of Noncompliance.  In the event the requirements of
                    -----------------------
this Section 2(e) are not complied with, the Corporation shall forthwith either
cause the closing of the transaction to be postponed until such requirements
have been complied with, or cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Series B Preferred Stock shall
revert to and be the same as such rights, preferences and privileges existing
immediately prior to the date of the first notice referred to in Section
2(e)(iii) hereof.

     3.   Redemption
          ----------

          (a)  At any time after December 19, 2002, but within thirty (30) days
(the "Redemption Date") after the receipt by this Corporation of a written
      ---------------
request from the holders of not less than a majority of the then outstanding
Series B Preferred Stock that all or some of such holders' shares be redeemed,
and concurrently with surrender by such holders of the certificates representing
such shares, this Corporation shall, to the extent it may lawfully do so, redeem
the shares specified in such request by paying in cash therefor a sum per share
equal to $4.50 per share of Series B Preferred Stock (as adjusted for any stock
dividends, combinations or splits with respect to such shares) (the "Redemption
                                                                     ----------
Price").  Any redemption effected pursuant to this Section 3(a) shall be made on
- -----
a pro rata basis among the holders of the Series B Preferred Stock delivering
such notice in proportion to the number of shares of Series B Preferred Stock
then held by such holders.

          (b)  At least fifteen (15) but no more than thirty (30) days prior to
each Redemption Date, written notice shall be mailed, first class postage
prepaid, to each holder of record (at the close of business on the business day
next preceding the day on which notice is given) of the Series B Preferred Stock
to be redeemed, at the address last shown on the records of this Corporation for
such holder, notifying such holder of the redemption to be effected, specifying
the number of shares to be redeemed from such holder, the Redemption Date, the
Redemption Price, the place at which payment may be obtained and calling upon
such holder to surrender to this Corporation, in the manner and at the place
designated, his, her or its certificate or certificates representing the shares
to be redeemed (the "Redemption Notice").  Except as provided in subsection
                     -----------------
(3)(c) on or after the Redemption Date, each holder of Series B Preferred Stock
to be redeemed shall surrender to this Corporation the certificate or
certificates representing such shares, in the manner and at the place designated
in the Redemption Notice, and thereupon the Redemption Price of such shares
shall be payable to the order of the person whose name appears on such
certificate or certificates as the owner thereof and each surrendered
certificate shall be canceled.  In the event less than all the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares.

          (c)  From and after the Redemption Date, unless there shall have been
a default in payment of the Redemption Price, all rights of the holders of
shares of Series B Preferred Stock designated for redemption in the Redemption
Notice as holders of Series B Preferred Stock (except the right to receive the
Redemption Price without interest upon surrender

                                      -20-


of their certificate or certificates) shall cease with respect to such shares,
and such shares shall not thereafter be transferred on the books of this
Corporation or be deemed to be outstanding for any purpose whatsoever. Subject
to the rights of series of Preferred Stock which may from time to time come into
existence, but in preference to shares of the Corporation's Series A Preferred
Stock, if the funds of the Corporation legally available for redemption of
shares of Series B Preferred Stock on any Redemption Date are insufficient to
redeem the total number of shares of Series B Preferred Stock to be redeemed on
such date, those funds which are legally available will be used to redeem the
maximum possible number of shares of Series B Preferred Stock ratably among the
holders of such shares to be redeemed based upon their holdings of Series B
Preferred Stock. The shares of Series B Preferred Stock not redeemed shall
remain outstanding and entitled to all the rights and preferences provided
herein. Subject to the rights of series of Preferred Stock which may from time
to time come into existence, but in preference to shares of the Corporation's
Series A Preferred Stock, at any time thereafter when additional funds of the
Corporation are legally available for the redemption of shares of Series B
Preferred Stock, such funds will immediately be used to redeem the balance of
the shares of Series B Preferred Stock which the Corporation has become obliged
to redeem on any Redemption Date but which it has not redeemed.

          (d)  On or prior to each Redemption Date, this Corporation shall
deposit the Redemption Price of all shares of Series B Preferred Stock
designated for redemption in the Redemption Notice, and not yet redeemed or
converted, with a bank or trust corporation having aggregate capital and surplus
in excess of $100,000,000 as a trust fund for the benefit of the respective
holders of the shares designated for redemption and not yet redeemed, with
irrevocable instructions and authority to the bank or trust corporation to
publish the notice of redemption thereof and pay the Redemption Price for such
shares to their respective holders on or after the Redemption Date, upon receipt
of notification from the Corporation that such holder has surrendered his, her
or its share certificate to the Corporation pursuant to Section (3)(b) above.
As of the date of such deposit (even if prior to the Redemption Date), the
deposit shall constitute full payment of the shares to their holders, and from
and after the date of the deposit the shares so called for redemption shall be
redeemed and shall be deemed to be no longer outstanding, and the holders
thereof shall cease to be shareholders with respect to such shares and shall
have no rights with respect thereto except the rights to receive from the bank
or trust corporation payment of the Redemption Price of the shares, without
interest, upon surrender of their certificates therefor, and the right to
convert such shares as provided in Section 4.  Such instructions shall also
provide that any moneys deposited by the Corporation pursuant to this Section
(3)(d) for the redemption of shares thereafter converted into shares of the
Corporation's Common Stock pursuant to Section 4 hereof prior to the Redemption
Date shall be returned to the Corporation forthwith upon such conversion.  The
balance of any moneys deposited by this Corporation pursuant to this Section
(3)(d) remaining unclaimed at the expiration of two (2) years following the
Redemption Date shall thereafter be returned to this Corporation upon its
request expressed in a resolution of its Board of Directors.

     4.   Conversion.  The holders of the Series B Preferred Stock shall have
          ----------
conversion rights as follows (the "Conversion Rights"):
                                   -----------------

                                      -21-


          (a)  Right to Convert. Subject to Section 4(c), each share of Series B
               ----------------
Preferred Stock shall be convertible, at the option of the holder thereof, at
any time after the date of issuance of such share, at the office of the
Corporation or any transfer agent for such stock, into such number of fully paid
and nonassessable shares of Common Stock as is determined by dividing $4.50 by
the Conversion Price applicable to such share, determined as hereafter provided
(the "Conversion Price"), in effect on the date the certificate is surrendered
for conversion.  The initial Conversion Price per share of Series B Preferred
Stock shall be $4.50.  Such initial Conversion Price shall be subject to
adjustment as set forth in Section 4(d).  Notwithstanding the foregoing, if a
holder of Series B Preferred Stock does not elect to convert pursuant to this
Section 4(a) prior to the day prior to the shareholder's meeting relating to any
distribution of any of the assets of the Corporation pursuant to Section 2(a),
then such holder of Series B Preferred Stock shall not be entitled to convert
pursuant to this Section 4(a).

          (b)  Automatic Conversion.  Each share of Series B Preferred Stock
               --------------------
shall automatically be converted into shares of Common Stock at the Conversion
Price at the time in effect for such share, except as provided below in Section
4(c),  immediately upon the Corporation's sale of its Common Stock in a firm
commitment underwritten public offering pursuant to a registration statement
under the Securities Act of 1933, as amended (the "Securities Act"), the public
                                                   --------------
offering price of which is not less than $9.00 per share (as adjusted to reflect
subsequent stock dividends, stock splits or recapitalizations occurring after
the date of issuance of the Series B Preferred Stock and prior to the closing of
such public offering) and which results in an aggregate public offering price of
at least $20,000,000.


          (c)  Mechanics of Conversion.  Before any holder of Series B Preferred
               -----------------------
Stock shall be entitled to convert the same into shares of Common Stock, such
holder shall surrender the certificate or certificates therefor, duly endorsed,
at the office of the Corporation or of any transfer agent for the Series B
Preferred Stock, and shall give written notice to the Corporation at its
principal corporate office, of the election to convert the same and shall state
therein the name or names in which the certificate or certificates for shares of
Common Stock are to be issued.  The Corporation shall, as soon as practicable
thereafter, issue and deliver at such office to such holder of Series B
Preferred Stock, or to the nominee or nominees of such holder, a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled as aforesaid.  Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
shares of such Series B Preferred Stock to be converted, and the person or
persons entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such shares of Common Stock as of such date.  If the conversion is in connection
with an underwritten offering of securities registered pursuant to the
Securities Act, the conversion may, at the option of any holder tendering such
shares of Series B Preferred Stock for conversion, be conditioned upon the
closing with the underwriters of the sale of securities pursuant to such
offering, in which event the person(s) entitled to receive Common Stock upon
conversion of such Series A Preferred Stock shall not be deemed to have
converted such Series B Preferred Stock until immediately prior to the closing
of such sale of securities.

                                      -22-


          (d)  Conversion Price Adjustments of Series B Preferred Stock for
               ------------------------------------------------------------
Certain Dilutive Issuances, Splits and Combinations.  The Conversion Price of
- ---------------------------------------------------
the Series B Preferred Stock shall be subject to adjustment from time to time as
follows:

               (i)  Issuance of Additional Stock below Purchase Price .  If the
                    --------------------------------------------------
Corporation shall issue, after the date upon which the shares of Series B
Preferred Stock were first issued (the "Purchase Date"), any Additional Stock
                                        -------------
(as defined below) without consideration or for a consideration per share less
than the Conversion Price for such series in effect immediately prior to the
issuance of such Additional Stock, the Conversion Price for such series in
effect immediately prior to each such issuance shall automatically be adjusted
as set forth in this Section 4(d)(i), unless otherwise provided in this Section
4(d)(i).

                    (A)  Adjustment.  Whenever the Conversion Price is adjusted
                         ----------
pursuant to this Section 4(d)(i), the new Conversion Price shall be the greater
of $2.50 or the price per share at which such Additional Stock is issued;
provided that, if at the time of such adjustment or as a result of such
adjustment the new Conversion Price shall be $2.50, then thereafter the new
Conversion Price pursuant to this Section 4(d)(i) shall be equal to the then
applicable conversion price of the Series A Preferred Stock under Section
4(d)(i) of the Series A Certificate (notwithstanding any redemption, conversion
or other elimination of the Series A Preferred Stock and not taking into account
the issuance and sale of the Series B Preferred Stock).

                    (B)  Definition of "Additional Stock".  For purposes of this
                         --------------------------------
Section 4(d)(i), "Additional Stock" shall mean any shares of Common Stock issued
                  ----------------
(or deemed to have been issued pursuant to Section 4(d)(i)(E)) by the
Corporation after the Purchase Date) other than:

                         (1)  Common Stock issued pursuant to a transaction
described in Section 4(d)(ii) hereof,

                         (2)  Shares of Common Stock issuable or issued to
employees, consultants or directors of the Corporation directly or pursuant to a
stock option plan, stock purchase plan or other stock plan approved by the Board
of Directors of the Corporation,

                         (3)  Capital stock, or options or warrants to purchase
capital stock, issued to financial institutions or lessors in connection with
commercial credit arrangements, equipment financings or similar transactions
approved by the Board of Directors of the Corporation,

                         (4)  Shares of Common Stock or Preferred Stock issuable
upon exercise of warrants outstanding as of the Purchase Date,

                         (5)  Capital stock or warrants or options to purchase
capital stock issued in connection with bona fide acquisitions, mergers or
similar transactions, the terms of which are approved by the Board of Directors
of the Corporation,

                                      -23-


                         (6)  Shares of Common Stock issued or issuable upon
conversion of the Corporation's Series A Preferred Stock or Series B Preferred
Stock, and

                         (7)  Shares of Common Stock issued or issuable in a
public offering prior to or in connection with which all outstanding shares of
Series B Preferred Stock will be converted to Common Stock.

                    (C)  No Fractional Adjustments.  No adjustment of the
                         -------------------------
Conversion Price for the Series B Preferred Stock shall be made in an amount
less than one cent per share, provided that any adjustments which are not
required to be made by reason of this sentence shall be carried forward and
shall be either taken into account in any subsequent adjustment made prior to
three years from the date of the event giving rise to the adjustment being
carried forward, or shall be made at the end of three years from the date of the
event giving rise to the adjustment being carried forward.

                    (D)  Determination of Consideration.  In the case of the
                         ------------------------------
issuance of Common Stock for cash, the consideration shall be deemed to be the
amount of cash paid therefor before deducting any reasonable discounts,
commissions or other expenses allowed, paid or incurred by the Corporation for
any underwriting or otherwise in connection with the issuance and sale thereof.
In the case of the issuance of the Common Stock for a consideration in whole or
in part other than cash, the consideration other than cash shall be deemed to be
the fair value thereof as determined by the Board of Directors irrespective of
any accounting treatment.

                    (E)  Deemed Issuances of Common Stock.  In the case of the
                         --------------------------------
issuance (whether before, on or after the applicable Purchase Date) of options
to purchase or rights to subscribe for Common Stock, securities by their terms
convertible into or exchangeable for Common Stock or options to purchase or
rights to subscribe for such convertible or exchangeable securities, the
following provisions shall apply for all purposes of this Section 4(d)(i):

                         (1)  The aggregate maximum number of shares of Common
Stock deliverable upon exercise (assuming the satisfaction of any conditions to
exercisability, including without limitation, the passage of time, but without
taking into account potential antidilution adjustments) of such options to
purchase or rights to subscribe for Common Stock shall be deemed to have been
issued at the time such options or rights were issued and for a consideration
equal to the consideration (determined in the manner provided in Section
4(d)(i)(D)), if any, received by the Corporation upon the issuance of such
options or rights plus the minimum exercise price provided in such options or
rights (without taking into account potential antidilution adjustments) for the
Common Stock covered thereby.

                         (2)  The aggregate maximum number of shares of Common
Stock deliverable upon conversion of or in exchange (assuming the satisfaction
of any conditions to convertibility or exchangeability, including, without
limitation, the passage of time, but without taking into account potential
antidilution adjustments) for any such convertible or exchangeable securities or
upon the exercise of options to purchase or rights to subscribe for such

                                      -24-


convertible or exchangeable securities and subsequent conversion or exchange
thereof shall be deemed to have been issued at the time such securities were
issued or such options or rights were issued and for a consideration equal to
the consideration, if any, received by the Corporation for any such securities
and related options or rights (excluding any cash received on account of accrued
interest or accrued dividends), plus the minimum additional consideration, if
any, to be received by the Corporation (without taking into account potential
antidilution adjustments) upon the conversion or exchange of such securities or
the exercise of any related options or rights (the consideration in each case to
be determined in the manner provided in Section 4(d)(i)(D)).

                         (3)  In the event of any change in the number of shares
of Common Stock deliverable or in the consideration payable to the Corporation
upon exercise of such options or rights or upon conversion of or in exchange for
such convertible or exchangeable securities, including, but not limited to, a
change resulting from the antidilution provisions thereof, the Conversion Price
of the Series B Preferred Stock, to the extent in any way affected by or
computed using such options, rights or securities, shall be recomputed to
reflect such change, but no further adjustment shall be made for the actual
issuance of Common Stock or any payment of such consideration upon the exercise
of any such options or rights or the conversion or exchange of such securities.

                         (4)  Upon the expiration of any such options or rights,
the termination of any such rights to convert or exchange or the expiration of
any options or rights related to such convertible or exchangeable securities,
the Conversion Price of the Series B Preferred Stock, to the extent in any way
affected by or computed using such options, rights or securities or options or
rights related to such securities, shall be recomputed to reflect the issuance
of only the number of shares of Common Stock (and convertible or exchangeable
securities which remain in effect) actually issued upon the exercise of such
options or rights, upon the conversion or exchange of such securities or upon
the exercise of the options or rights related to such securities.

                         (5)  The number of shares of Common Stock deemed issued
and the consideration deemed paid therefor pursuant to Sections 4(d)(i)(E)(1)
and 4(d)(i)(E)(2) shall be appropriately adjusted to reflect any change,
termination or expiration of the type described in either Section 4(d)(i)(E)(3)
or 4(d)(i)(E)(4).

               (F)  No Increased Conversion Price.  Notwithstanding any other
                    -----------------------------
provisions of this Section (4)(d)(i), except to the limited extent provided for
in Sections 4(d)(i)(E)(3) and 4(d)(i)(E)(4), no adjustment of the Conversion
Price pursuant to this Section 4(d)(i) shall have the effect of increasing the
Conversion Price above the Conversion Price in effect immediately prior to such
adjustment.

          (ii) Stock Splits and Dividends.  In the event the Corporation should
               --------------------------
at any time or from time to time after the Purchase Date fix a record date for
the effectuation of a split or subdivision of the outstanding shares of Common
Stock or the determination of holders of Common Stock entitled to receive a
dividend or other distribution payable in additional shares of Common Stock or
other securities or rights convertible into, or entitling the holder thereof to

                                      -25-


receive directly or indirectly, additional shares of Common Stock (hereinafter
referred to as "Common Stock Equivalents") without payment of any consideration
                ------------------------
by such holder for the additional shares of Common Stock or the Common Stock
Equivalents (including the additional shares of Common Stock issuable upon
conversion or exercise thereof), then, as of such record date (or the date of
such dividend distribution, split or subdivision if no record date is fixed),
the Conversion Price of the Series B Preferred Stock shall be appropriately
decreased so that the number of shares of Common Stock issuable on conversion of
each share of such Series shall be increased in proportion to such increase of
the aggregate of shares of Common Stock outstanding and those issuable with
respect to such Common Stock Equivalents with the number of shares issuable with
respect to Common Stock Equivalents determined from time to time in the manner
provided for deemed issuances in Section 4(d)(i)(E).

               (iii) Reverse Stock Splits.  If the number of shares of Common
                     --------------------
Stock outstanding at any time after the Purchase Date is decreased by a
combination of the outstanding shares of Common Stock, then, following the
record date of such combination, the Conversion Price for the Series B Preferred
Stock shall be appropriately increased so that the number of shares of Common
Stock issuable on conversion of each share of such Series shall be decreased in
proportion to such decrease in outstanding shares.


          (e)  Other Distributions. In the event the Corporation shall declare a
               -------------------
distribution payable in securities of other persons, evidences of indebtedness
issued by the Corporation or other persons, assets (excluding cash dividends) or
options or rights not referred to in Section 4(d)(ii), then, in each such case
for the purpose of this Section 4(e), the holders of Series B Preferred Stock
shall be entitled to a proportionate share of any such distribution as though
they were the holders of the number of shares of Common Stock of the Corporation
into which their shares of Series B Preferred Stock are convertible as of the
record date fixed for the determination of the holders of Common Stock of the
Corporation entitled to receive such distribution.

          (f)  Recapitalizations.  If at any time or from time to time there
               -----------------
shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 4 or Section 2), provision shall be made so that the holders of the
Series B Preferred Stock shall thereafter be entitled to receive upon conversion
of the Series B Preferred Stock the number of shares of stock or other
securities or property of the Corporation or otherwise, to which a holder of
Common Stock deliverable upon conversion would have been entitled on such
recapitalization.  In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 4 with respect to the rights of
the holders of the Series B Preferred Stock after the recapitalization to the
end that the provisions of this Section 4 (including adjustment of the
Conversion Price then in effect and the number of shares purchasable upon
conversion of the Series B Preferred Stock) shall be applicable after that event
and be as nearly equivalent as practicable.

          (g)  No Impairment.  The Corporation will not, by amendment of its
               -------------
Articles of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to

                                      -26-


avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Corporation, but will at all times in good faith
assist in the carrying out of all the provisions of this Section 4 and in the
taking of all such action as may be necessary or appropriate in order to protect
the Conversion Rights of the holders of Series B Preferred Stock against
impairment.

          (h)  No Fractional Shares and Certificate as to Adjustments
               ------------------------------------------------------

               (i)  No fractional shares shall be issued upon the conversion of
any share or shares of the Series B Preferred Stock, and the number of shares of
Common Stock to be issued shall be rounded to the nearest whole share. The
number of shares issuable upon such conversion shall be determined on the basis
of the total number of shares of Series B Preferred Stock the holder is at the
time converting into Common Stock and the number of shares of Common Stock
issuable upon such aggregate conversion.

               (ii) Upon the occurrence of each adjustment or readjustment of
the Conversion Price of Series B Preferred Stock pursuant to this Section 4, the
Corporation, at its expense, shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of such Preferred Stock a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any holder of Series B Preferred Stock, furnish or cause to be furnished
to such holder a like certificate setting forth (A) such adjustment and
readjustment, (B) the Conversion Price for the Series B Preferred Stock at the
time in effect, and (C) the number of shares of Common Stock and the amount, if
any, of other property which at the time would be received upon the conversion
of a share of the Series B Preferred Stock.

          (i)  Notices of Record Date.  In the event of any taking by the
               ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series B Preferred Stock, at least ten (10) days
prior to the date specified therein, a notice specifying the date on which any
such record is to be taken for the purpose of such dividend, distribution or
right, and the amount and character of such dividend, distribution or right.

          (j)  Reservation of Stock Issuable Upon Conversion.  The Corporation
               ---------------------------------------------
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series B Preferred Stock, such number of its shares of Common
Stock as shall from time to time be sufficient to effect the conversion of all
outstanding shares of Series B Preferred Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of Series B Preferred Stock, in
addition to such other remedies as shall be available to the holders of Series B
Preferred Stock, the Corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but

                                      -27-


unissued shares of Common Stock to such number of shares as shall be sufficient
for such purposes, including, without limitation, engaging in best efforts to
obtain the requisite shareholder approval of any necessary amendment to the
Articles of Incorporation.

          (k)  Notices.  Any notice required by the provisions of this Section 4
               -------
to be given to the holders of shares of Series B Preferred Stock shall be deemed
given if deposited in the United States mail, postage prepaid, and addressed to
each holder of record at such holder's address appearing on the books of the
Corporation.

     5.   Voting Rights.  The holder of each share of Series B Preferred Stock
          -------------
shall have the right to one vote for each share of Common Stock into which the
Series B Preferred Stock could then be converted, and with respect to such vote,
such holder shall have full voting rights and powers equal to the voting rights
and powers of the holders of Common Stock, and shall be entitled,
notwithstanding any provision hereof, to notice of any shareholders' meeting in
accordance with the bylaws of the Corporation, and shall be entitled to vote,
together with holders of Common Stock, with respect to any question upon which
holders of Common Stock have the right to vote.  Fractional votes shall not,
however, be permitted and any fractional voting rights available on an as-
converted basis (after aggregating all shares into which shares of Series B
Preferred Stock held by each holder could be converted) shall be rounded to the
nearest whole number (with one-half being rounded upward).

     6.   Protective Provisions.  So long as any shares of Series B Preferred
          ---------------------
Stock are outstanding, the Corporation shall not without first obtaining the
approval (by vote or written consent, as provided by law) of the holders of at
least two-thirds of the then outstanding shares of Series B Preferred Stock,
voting together as a class:

          (a)  effect a transaction described in Section 2(e)(i) above;

          (b)  alter or change the rights, preferences or privileges of the
shares of Series B Preferred Stock so as to affect adversely the shares of such
series;

          (c)  amend the Corporation's Articles of Incorporation or Bylaws or
change the authorized number of directors of the Corporation;

          (d)  authorize or issue, or obligate itself to issue, any other equity
security, including any other security convertible into or exercisable for any
equity security, having a preference over, or being on a parity with, the Series
B Preferred Stock with respect to preference, redemption or dividends;

          (e)  issue, or obligate itself to issue, any equity security, or any
security convertible into or exercisable for any equity security, if, after such
issuance, the Company would have outstanding more than 12,000,000 equity
securities (assuming for this purpose the issuance of all securities reserved
for issuance under stock option plans, stock purchase plans and other stock
plans approved by the Board of Directors of the Company, and exercise of all
then outstanding rights to acquire equity securities);

                                      -28-


          (f)  redeem, purchase or otherwise acquire (or pay into or set funds
aside for a sinking fund for such purpose) any share or shares of Preferred
Stock or Common Stock; provided, however, that this restriction shall not apply
                       --------  -------
to the redemption of Series B Preferred Stock pursuant to Article 3 hereof and
provided further, however, that any such redemption, purchase or other
- ----------------  -------
acquisition of any shares of Series A Preferred Stock pursuant to Article 3 of
the Series A Certificate shall require either such approval of the Series B
Preferred Stock or the expiration of ten (10) days after notice of such
redemption, purchase or other acquisition is given to the holders of the Series
B Preferred Stock (during which ten (10) day period the holders of the Series B
Preferred Stock may exercise their right to redemption pursuant to Section 3
hereof prior to and in preference to the holders of the Series A Preferred
Stock); or

          (g)  declare or pay any dividends or other distributions on
outstanding capital stock of the Corporation.

     7.   Status of Redeemed or Converted Stock.  In the event any shares of
          -------------------------------------
Series B Preferred Stock shall be redeemed pursuant to Section 3 hereof or
converted pursuant to Section 4 hereof, the shares so redeemed or converted
shall be canceled and shall not be issuable by the Corporation.  Upon redemption
pursuant to Section 3 hereof or conversion pursuant to Section 4 hereof of all
outstanding shares of Series B Preferred Stock, all provisions of this
Certificate of Designation shall cease to be of further effect.  Upon the
occurrence of such event, the Board of Directors shall have the power, pursuant
to Minnesota Statutes, Section 302A.135, Subd. 5 or any successor provision and
without shareholder action, to cause restated articles of incorporation of the
Corporation or other appropriate documents to be prepared and filed with the
Secretary of State of the State of Minnesota which reflect the removal of all
provisions relating to the Series B Preferred Stock and the cancellation of this
Certificate of Designation.

     8.   Par Value; No Cumulative Voting; No Preemptive Rights.  The Series B
          -----------------------------------------------------
Preferred Stock shall have a par value of $0.01 per share.  Holders of Series B
Preferred Stock shall not be entitled to cumulate their votes in any election of
directors in which they are entitled to vote and shall not be entitled to any
preemptive rights under the Corporation's Articles of Incorporation to acquire
shares of any class or series of capital stock of the Corporation.
