                            STATEMENT OF DESIGNATION

                                       OF

                            SERIES A PREFERRED STOCK

                                       OF

                                 SURMODICS, INC.

                        (Pursuant to Chapter 302A of the
                       Minnesota Business Corporation Act)


                                -----------------

         SurModics, Inc., a corporation organized and existing under the
Minnesota Business Corporation Act (hereinafter called the "Company"), hereby
certifies that the following resolution was adopted by the Board of Directors of
the Company at a meeting duly called and held on March 22, 1999:

         RESOLVED, that, pursuant to the authority granted to and vested in the
Board of Directors of the Company (hereinafter called the "Board of Directors"
or the "Board") in accordance with the provisions of Section 3.1 of the Articles
of Incorporation, as amended to date (hereinafter called the "Articles of
Incorporation"), the Board of Directors hereby creates a series of Preferred
Stock, par value $.05 per share (the "Preferred Stock"), of the Company and
hereby states the designation and number of shares, and fixes the relative
rights, preferences, and limitations thereof as follows:

         Series A Preferred Stock:

         Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Preferred Stock" (the "Series A Preferred Stock"), and
the number of shares constituting the Series A Preferred Stock shall be One
Hundred Fifty Thousand (150,000). Such number of shares may be increased or
decreased by resolution of the Board of Directors; provided, that, no decrease
shall reduce the number of shares of Series A Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the exercise of outstanding options, rights or warrants or
upon the conversion of any outstanding securities issued by the Company
convertible into Series A Preferred Stock.

         Section 2.  Dividends and Distributions.

         (A) Subject to the rights of the holders of any shares of any series of
Preferred Stock, par value $.05 per share (the "Preferred Stock"), of the
Company or Preferred Stock (or any similar stock) ranking prior and superior to
the Series A Preferred Stock with respect to




                                       3
   4

dividends, the holders of shares of Series A Preferred Stock, in preference to
the holders of Common Stock, par value $.05 per share (the "Common Stock"), of
the Company, and of any other junior stock, shall be entitled to receive, when,
as and if declared by the Board of Directors out of funds legally available for
the purpose, quarterly dividends payable in cash on the first day of March,
June, September and December in each year (each such date being referred to
herein as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a share or fraction
of a share of Series A Preferred Stock, in an amount per share (rounded to the
nearest cent) equal to the greater of (a) $1 or (b) subject to the provision for
adjustment hereinafter set forth, 100 times (as adjusted, the "Dividend
Multiple") the aggregate per share amount of all cash dividends, and 100 times
the aggregate per share amount (payable in kind) of all non-cash dividends or
other distributions, other than a dividend payable in shares of Common Stock or
a subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock since the immediately preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment Date, since the first issuance of any share or fraction of a share of
Series A Preferred Stock. In the event the Company shall at any time declare or
pay any dividend on the Common Stock payable in shares of Common Stock, or
effect a subdivision or combination or consolidation of the outstanding shares
of Common Stock (by reclassification or otherwise) into a greater or lesser
number of shares of Common Stock, then in each such case the Dividend Multiple
shall be adjusted by multiplying such amount by a fraction, the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

         (B) The Company shall declare a dividend or distribution on the Series
A Preferred Stock as provided in paragraph (A) of this Section immediately after
it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock); provided, that, in the event no
dividend or distribution shall have been declared on the Common Stock during the
period between any Quarterly Dividend Payment Date and the next subsequent
Quarterly Dividend Payment Date, a dividend of $1 per share on the Series A
Preferred Stock shall nevertheless be payable on such subsequent Quarterly
Dividend Payment Date.

         (C) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares, unless the date of issue of such
shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of Series A Preferred Stock entitled to receive a quarterly dividend
and before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative from such Quarterly Dividend
Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends
paid on the shares of Series A Preferred Stock in an amount less than the total
amount of such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding. The Board of Directors may fix a record date for the determination
of holders of shares of Series A Preferred




                                       4
   5

Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be not more than sixty (60) days prior to the
date fixed for the payment thereof.

         Section 3. Voting Rights. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

                (A) Subject to the provision for adjustment hereinafter set
         forth, each share of Series A Preferred Stock shall entitle the holder
         thereof to 100 votes (as adjusted, the "Vote Multiple") on all matters
         submitted to a vote of the stockholders of the Company. In the event
         the Company shall at any time declare or pay any dividend on the Common
         Stock payable in shares of Common Stock, or effect a subdivision or
         combination or consolidation of the outstanding shares of Common Stock
         (by reclassification or otherwise) into a greater or lesser number of
         shares of Common Stock, then in each such case the Vote Multiple shall
         be adjusted by multiplying such number by a fraction, the numerator of
         which is the number of shares of Common Stock outstanding immediately
         after such event and the denominator of which is the number of shares
         of Common Stock that were outstanding immediately prior to such event.

                (B) Except as otherwise provided in Section 10 hereof, in
         any other Statement of Designation creating a series of Preferred Stock
         or any similar stock, or by law, the holders of shares of Series A
         Preferred Stock and the holders of shares of Common Stock and any other
         capital stock of the Company having general voting rights shall vote
         together as one class on all matters submitted to a vote of
         stockholders of the Company.

                (C) Except as set forth herein, or as otherwise provided by
         law, holders of Series A Preferred Stock shall have no special voting
         rights and their consent shall not be required (except to the extent
         they are entitled to vote with holders of Common Stock as set forth
         herein) for taking any corporate action.

         Section 4. Certain Restrictions.

                (A) Whenever quarterly dividends or other dividends or
         distributions payable on the Series A Preferred Stock as provided in
         Section 2 are in arrears, thereafter and until all accrued and unpaid
         dividends and distributions, whether or not declared, on shares of
         Series A Preferred Stock outstanding shall have been paid in full, the
         Company shall not:

                    (i)    declare or pay dividends, or make any other
                distributions, on any shares of stock ranking junior (either as
                to dividends or upon liquidation, dissolution or winding up) to
                the Series A Preferred Stock;

                    (ii)   declare or pay dividends, or make any other
                distributions, on any shares of stock ranking on a parity
                (either as to dividends or upon liquidation, dissolution or
                winding up) with the Series A Preferred Stock, except dividends
                paid ratably on the Series A Preferred Stock and all such parity
                stock on which




                                       5
   6

                dividends are payable or in arrears in proportion to the total
                amounts to which the holders of all such shares are then
                entitled;

                    (iii) redeem or purchase or otherwise acquire for
                consideration shares of any stock ranking junior (either as to
                dividends or upon liquidation, dissolution or winding up) to the
                Series A Preferred Stock, provided that the Company may at any
                time redeem, purchase or otherwise acquire shares of any such
                junior stock in exchange for shares of any stock of the Company
                ranking junior (as to dividends and upon dissolution,
                liquidation and winding up) to the Series A Preferred Stock; or

                    (iv)  redeem or purchase or otherwise acquire for
                consideration any shares of Series A Preferred Stock, or any
                shares of stock ranking on a parity (either as to dividends or
                upon liquidation, dissolution or winding up) with the Series A
                Preferred Stock, except in accordance with a purchase offer made
                in writing or by publication (as determined by the Board) to all
                holders of such shares upon such terms as the Board, after
                consideration of the respective annual dividend rates and other
                relative rights and preferences of the respective series and
                classes, shall determine in good faith will result in fair and
                equitable treatment among the respective series or classes.

                (B) The Company shall not permit any subsidiary of the Company
         to purchase or otherwise acquire for consideration any shares of stock
         of the Company unless the Company could, under paragraph (A) of this
         Section 4, purchase or otherwise acquire such shares at such time and
         in such manner.

         Section 5. Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Company in any manner whatsoever shall be
retired and cancelled promptly after the acquisition thereof. All such shares
shall upon their cancellation become authorized but unissued shares of Preferred
Stock and may be reissued as part of a new series of Preferred Stock subject to
the conditions and restrictions on issuance set forth herein, in the Articles of
Incorporation, or in any other Statement of Designation creating a series of
Preferred Stock or any similar stock or as otherwise required by law.

         Section 6. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Company, no distribution shall be
made (A) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received the greater of (i) $100 per share, plus an
amount equal to accrued and unpaid dividends and distributions thereon, whether
or not declared, to the date of such payment, or (ii) subject to the provision
for adjustment hereinafter set forth, 100 times (as adjusted, the "Liquidation
Preference Multiple") the aggregate amount to be distributed per share to
holders of shares of Common Stock, or (B) to the holders of shares of stock
ranking on a parity (either as to dividends or upon liquidation, dissolution or
winding up) with the Series A Preferred Stock, except distributions made ratably
on the Series A Preferred Stock and all such parity stock in proportion to the
total amounts to which the holders of all such shares are entitled




                                       6
   7

upon such liquidation, dissolution or winding up. In the event the Company shall
at any time declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise) into a
greater or lesser number of shares of Common Stock, then in each such case the
Liquidation Preference Multiple shall be adjusted by multiplying such amount by
a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

         Section 7.  Consolidation, Merger, Etc. In case the Company shall enter
into any consolidation, merger, statutory exchange combination or other
transaction in which the shares of Common Stock are exchanged for or changed
into other stock or securities, cash and/or any other property, then in any such
case each share of Series A Preferred Stock shall at the same time be similarly
exchanged or changed into an amount per share, subject to the provision for
adjustment hereinafter set forth, equal to 100 times (as adjusted, the "Exchange
Multiple") the aggregate amount of stock, securities, cash and/or any other
property (payable in kind), as the case may be, into which or for which each
share of Common Stock is changed or exchanged. In the event the Company shall at
any time declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise) into a
greater or lesser number of shares of Common Stock, then in each such case the
Exchange Multiple shall be adjusted by multiplying such amount by a fraction,
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

         Section 8.  No Redemption. The shares of Series A Preferred Stock shall
not be redeemable.

         Section 9.  Rank. The Series A Preferred Stock shall rank, with respect
to the payment of dividends and the distribution of assets, junior to all series
of any other class of Preferred Stock hereafter issued that specifically provide
that they shall rank senior to the Series A Preferred Stock.

         Section 10. Amendment. If any proposed amendment to the Articles of
Incorporation or this Statement of Designation would alter or change the
preferences, special rights or powers given to the Series A Preferred Stock so
as to affect the Series A Preferred Stock adversely, or would authorize the
issuance of a class or classes of stock having preferences or rights with
respect to dividends or dissolutions or the distribution of assets that would be
superior to the preferences or rights of the Series A Preferred Stock, then the
holders of the Series A Preferred Stock shall be entitled to vote as a series
upon such amendment, and the affirmative vote of two-thirds of the outstanding
shares of Series A Preferred Stock shall be necessary to the adoption thereof,
in addition to such other vote as may be required by the Minnesota Business
Corporation Act.



                                       7
   8

         Section 11. Fractional Shares. Series A Preferred Stock may be issued
in fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series A Preferred Stock.

         I certify that I am authorized to execute this Statement of
Designation, and I further certify that I understand that by signing this
Statement of Designation I am subject to the penalties of perjury as set forth
in Minnesota Statutes, Section 609.48, as if I had signed this Statement of
Designation under oath.

                  shares, and the Preferred Stock are hereinafter referred to

                  shares), and to fix the relative rights and preferences of
                  each such class or series."

such section:

                                    "(d) If and when all outstanding shares of

                           Section 4.5, such shares shall be deemed canceled and
                           shall not be reissuable by the corporation, this
                           Section 4.5 shall be null and void and any
                           restatement of these Articles of Incorporation may
                           exclude this Section 4.5 and the reference to Series

         We, the undersigned, DALE R. OLSETH and DAVID R. BUSCH, the

         3.4)  Issuance of Shares to Holders of Another Class or Series. The
Board is further authorized to issue shares of one class or series of Capital

another class or series of Capital Stock to effect share dividends or splits.

         ARTICLE 4 - RIGHTS AND PRIVILEGES OF SHARES AND OF SHAREHOLDERS

         The rights, preferences, privileges and restrictions granted to or
imposed upon the Capital Stock or the holders thereof are set forth below.

         4.1)  Voting Privileges. Each holder of Voting Common Stock shall have
one vote on all matters submitted to the shareholders for each share of Voting
Common Stock standing in the name of such holder on the books of the
corporation. Each holder of Preferred Stock shall have one vote on all matters
submitted to the shareholders for each share of Voting Common Stock which such
holder of Preferred Stock would be entitled to receive upon the conversion of
his Preferred Stock as provided in subsection 4.5(c). In addition, each holder
of Preferred Stock shall have the special voting rights which are described in
subsection 4.5(b). Except as may be required by the Minnesota Business
Corporation Act, the holders of Nonvoting Common Stock shall have no voting
rights with respect to any matter submitted to a vote of the shareholders of the
corporation.

         4.2)  Preemptive Rights. No holder of shares of any class or series of
Capital Stock shall be entitled as such, as a matter of right, to subscribe for
or purchase additional shares of that class or series or any other class or
series of Capital Stock of the corporation now or hereafter authorized or
issued.

         4.3)  No Cumulative Voting. There shall be no cumulative voting by the
shareholders of the corporation.

         4.4)  Distributions. Except as provided in subsection 4.5(a) on the
liquidation, dissolution or winding up of the corporation, shares of Capital
Stock shall share ratably in any dividends or distributions of the corporation,
whether paid in cash, property or stock.

         4.5)  Series A Convertible Preferred Stock.

               (a) Liquidation Preference. In the event of the liquidation,
         dissolution or winding up of the corporation, whether voluntary or
         involuntary, the holders of the Preferred Stock shall be entitled to
         receive out of assets of the corporation, an amount equal to $13.50
         (hereinafter referred to as the "Liquidation Preference") for each
         outstanding share of Preferred Stock before any payment shall be made
         or any assets distributed to the holders of Voting Common Stock or
         Nonvoting Common Stock or any other class of stock of this corporation
         ranking junior to the Preferred Stock upon liquidation or dissolution
         of the corporation. If, upon any liquidation, dissolution, or winding
         up of the corporation, the assets of the corporation are insufficient
         to pay the Liquidation Preference for each outstanding share of
         Preferred Stock, the holders of Preferred Stock shall share pro rata in
         any such distribution in proportion to the full




                                       15
   16

         amounts to which they would otherwise be entitled. If, upon any
         liquidation, dissolution or winding up of the corporation, the holders
         of Preferred Stock would be entitled to receive in excess of the
         Liquidation Preference for each outstanding share of Preferred Stock in
         any such distribution if all such shares of Preferred Stock had been
         converted to shares of Voting Common Stock pursuant to subsection
         4.5(c), instead of receiving the Liquidation Preference, each holder of
         Preferred Stock shall receive an amount equal to the distribution such
         holder would receive if all his outstanding shares of Preferred Stock
         had been converted to shares of Voting Common Stock pursuant to
         subsection 4.5(c) on the day preceding the date of such liquidation,
         dissolution or winding up. The Liquidation Preference shall be
         appropriately adjusted to reflect stock splits and reverse stock splits
         of the Preferred Stock or dividends or distributions payable in shares
         of Preferred Stock. Nothing hereinabove set forth shall affect in any
         way the right or obligation of each holder of shares of Preferred Stock
         to convert such shares into shares of Voting Common Stock, at any time
         and from time to time, in accordance with subsection 4.5(c) below.

                  (b)      Special Voting Rights. Without the affirmative vote
         of the holders (acting together as a class) of at least a majority of
         the Preferred Stock at the time outstanding given in person or by proxy
         at any annual meeting, or at such special meeting called for that
         purpose, or, if permitted by law, in writing without a meeting, the
         corporation shall not:

                           (1) authorize or issue any shares of stock having
                  priority over the Preferred Stock as to the payment of
                  dividends or the payment or distribution of assets upon the
                  liquidation or dissolution, voluntary or involuntary, of the
                  corporation; or

                           (2) amend the Articles of Incorporation of the
                  corporation so as to alter this Article 4 in any respect.

                  (c)      Conversion Rights; Mandatory Conversion.

                           (1) At the option of the holder thereof, each share
                  of Preferred Stock shall be convertible, at the offices of the
                  corporation (or at such other office or offices, if any, as
                  the Board of Directors may designate), into one (1) share of
                  Voting Common Stock of the corporation, subject to adjustment
                  as provided in subsection 4.5(c)(2) below. In order to convert
                  shares of Preferred Stock into shares of Voting Common Stock,
                  the holder thereof, shall surrender at the principal executive
                  offices of the corporation the certificate or certificates
                  therefor, duly endorsed to the corporation or in blank, and
                  give written notice to the corporation at such office that
                  such holder elects to convert a specified portion or all of
                  such shares of Preferred Stock into shares of Voting Common
                  Stock. Shares of Preferred Stock shall be deemed to have been
                  converted on the day of surrender of the certificate
                  representing such shares for conversion in accordance with the
                  foregoing provisions (the "Conversion Date"), and the person
                  entitled to receive the shares of Voting Common Stock of the
                  corporation issuable upon such conversion shall be treated for
                  all purposes as the record holder of such shares of



                                       16
   17

                  Voting Common Stock at that time. As promptly as practicable
                  on or after the Conversion Date, the corporation shall issue
                  and mail or deliver or cause to be issued and mailed or
                  delivered to such holder a certificate or certificates for the
                  number of shares of Voting Common Stock issuable upon
                  conversion and a certificate or certificates for the balance
                  of the Preferred Stock surrendered, if any, not so converted
                  into shares of Voting Common Stock.

                           (2)      The number of shares of Voting Common Stock
                  issuable in exchange for shares of Preferred Stock upon the
                  exercise of these conversion rights (the "Conversion Ratio"),
                  which shall initially be one share of Voting Common Stock for
                  one share of Preferred Stock, shall be subject to adjustment
                  from time to time as hereinafter provided:

                                    (i)   In case the corporation shall at any
                           time subdivide or split its outstanding Common Stock
                           into a greater number of shares, the Conversion Ratio
                           in effect immediately prior to such subdivision or
                           split shall be proportionately increased; and,
                           conversely, in case the outstanding Common Stock of
                           the corporation shall be combined into a smaller
                           number of shares the Conversion Ratio in effect
                           immediately prior to such combination shall be
                           proportionately reduced.

                                    (ii)  If any capital reorganization or
                           reclassification of the Capital Stock of the
                           corporation or consolidation or merger of the
                           corporation with another corporation or the sale of
                           all or substantially all of its assets to another
                           corporation shall be affected in such a way that
                           holders of Common Stock shall be entitled to receive
                           stock, securities or assets with respect to or in
                           exchange for Common Stock, then, as a condition of
                           such reorganization, reclassification, consolidation,
                           merger or sale, lawful and adequate provision shall
                           be made whereby the holders of Preferred Stock shall
                           thereafter have the right to receive, in lieu of the
                           Voting Common Stock of the corporation immediately
                           theretofore receivable upon the conversion of any
                           such Preferred Stock, such shares of stock,
                           securities or assets as may be issued or payable with
                           respect to or in exchange for a number of outstanding
                           shares of Voting Common Stock equal to the number of
                           shares of Voting Common Stock immediately theretofore
                           receivable upon the conversion of such Preferred
                           Stock had such reorganization, reclassification,
                           consolidation, merger or sale not taken place; and,
                           in any such case, appropriate provision shall be made
                           with respect to the rights and interests of the
                           holders of the Preferred Stock to the end that the
                           provisions hereof (including without limitation
                           provisions for adjustments of the Conversion Ratio
                           and of the number of shares receivable upon the
                           conversion of such Preferred Stock) shall thereafter
                           be applicable as nearly as may be, in relation to any
                           shares of stock, securities or assets hereafter
                           receivable upon the conversion of such Preferred
                           Stock. The corporation shall not effect any such
                           consolidation, merger or sale, unless prior to the
                           consummation thereof the surviving

                           corporation (if other than the corporation), the
                           corporation resulting from such consolidation or the
                           corporation purchasing such assets shall assume by
                           written instrument executed and mailed to the
                           registered holders of the Preferred Stock at the last
                           address of such holders appearing on the books of the
                           corporation, the obligation to deliver to such
                           holders such shares of stock, securities or assets
                           as, in accordance with the foregoing provisions, such
                           holders may be entitled to receive.

                                    (iii) If and whenever the corporation shall
                           issue or sell any Common Stock for a consideration
                           per share less than the Liquidation Preference
                           (except for the issuance or sale of up to 50,000
                           shares of Nonvoting Common Stock pursuant to the
                           corporation's 1984 Stock Option Plan, up to 200,000
                           shares of Voting Common Stock pursuant to the
                           corporation's 1987 Stock Option Plan and up to 50,000
                           shares of Voting Common Stock to Simplot Development
                           Corporation (hereinafter referred to as the "Excluded
                           Stock Issuances")) or shall issue any options,
                           warrants or other rights for the purchase of shares
                           of Common Stock at a consideration per share of less
                           than the Liquidation Preference, forthwith upon such
                           issuance or sale of such shares, options, warrants or
                           other rights for purchase, the Conversion Ratio in
                           effect immediately prior to such issuance or sale for
                           the Preferred Stock shall be adjusted so that each
                           share of Preferred Stock shall thereafter be
                           convertible into that number of shares of Voting
                           Common Stock as is equal to the number determined by
                           multiplying the Conversion Ratio by a fraction, the
                           numerator of which shall be the amount determined by
                           multiplying (aa) the number of shares of Common Stock
                           outstanding immediately after such issuance or sale
                           plus the number of shares of Common Stock issuable
                           upon the exercise of any purchase rights thus issued,
                           by (bb) the Liquidation Preference, and the
                           denominator of which shall be an amount equal to the
                           sum of (aa) the number of shares of Common Stock
                           outstanding immediately prior to such issuance or
                           sale multiplied by the Liquidation Preference, and
                           (bb) the total consideration payable to the
                           corporation upon such issuance or sale of such shares
                           and such purchase rights and upon the exercise of
                           such purchase rights. If any options or purchase
                           rights taken into account in any such adjustment of
                           the Conversion Ratio subsequently expire without
                           exercise, the Conversion Ratio shall be recomputed by
                           deleting such options or purchase rights. For
                           purposes of this subsection 4.5(c)(2), the number of
                           shares of Voting Common Stock or Nonvoting Common
                           Stock which may be issued as Excluded Stock Issuances
                           shall be appropriately adjusted to reflect stock
                           splits, stock dividends, reorganizations,
                           consolidations and similar changes.

                                    (iv)  The anti-dilution provisions of this
                           subsection 4.5(c)(2) may be waived by the affirmative
                           vote of the holders (acting together as a class) of
                           at least a majority of the then outstanding shares of
                           Preferred Stock.

                           (3)      Upon receipt of a written notice to the
                  corporation from a holder of shares of Preferred Stock
                  delivered to the corporation's principal executive offices
                  requesting a computation of the then current Conversion Ratio,
                  the corporation shall promptly give written notice by

                           (4)      In case any time:

                                    (i)   the corporation shall pay any dividend

                           distribution (other than regular cash dividends) to
                           the holders of its Common Stock; or

                                    (ii)  the corporation shall offer for
                           subscription pro rata to the holders of its Common
                           Stock any additional shares of stock of any class or
                           other rights; or

                                    (iii) there shall be any capital
                           reorganization, reclassification of the Capital Stock
                           of the corporation or consolidation or merger of the

                           the corporation; then in any one or more of said
                           cases the corporation shall give written notice, by
                           first-class mail, postage prepaid, addressed to the
                           holders of the Preferred Stock at the addresses of
                           such holders as shown on the books of this
                           corporation, of the date on which (aa) the books of
                           the corporation shall close or a record shall be
                           taken for such dividend, distribution or subscription
                           rights or (bb) such reorganization, reclassification,
                           consolidation, merger, sale, dissolution, liquidation

                           Such notice shall also specify the date as of which
                           the holders of Common Stock of record shall
                           participate in such dividend, distribution or
                           subscription rights or shall be entitled to exchange
                           their Common Stock for securities or other property

                           20 days prior to the action in question and not less
                           than 20 days prior to the record date or the date on

                           (5)      As used in this subsection 4.5(c), the term

                                       19

                  and Nonvoting Common Stock and shall also include any capital
                  stock of any class of the corporation hereafter authorized
                  which shall have the right to vote on all matters submitted to
                  the shareholders of the corporation and shall not be limited
                  to a fixed sum or percentage in respect of the rights of the
                  holders thereof to participate in dividends or in the
                  distribution of assets upon the voluntary or involuntary
                  liquidation, dissolution or winding up of the corporation;
                  provided that the shares receivable pursuant to conversion of
                  the Preferred Stock shall include shares designated as Voting
                  Common Stock of the corporation as of the date of issuance of
                  such Preferred Stock or, in the case of any reclassification
                  of the outstanding shares thereof, the stock, securities or
                  assets provided for in subsection 4.5(c)(2)(ii) above.

                           (6)      The number of shares of Voting Common Stock
                  issuable upon conversion of shares of Preferred Stock shall be
                  computed to the nearest one hundredth of a full share;
                  however, no fractional shares of Voting Common Stock shall be
                  issued upon conversion. The corporation shall pay a cash
                  adjustment in respect of any fraction of a share in an
                  amount-equal to the same fraction of the market price per
                  share of Voting Common Stock as of the close of business on
                  the day of conversion. "Market price" shall mean the average
                  of the high and low prices of the Voting Common Stock sales on
                  all exchanges on which the Voting Common Stock may at the time
                  be listed or as reported by the National Association of
                  Securities Dealers, Inc. Automated Quotation System National
                  Market System ("NASDAQ-NMS"), or, if there shall have been no
                  sales on any such exchange or as reported by NASDAQ-NMS on any
                  such day, the average of the bid and asked prices at the end
                  of such day, or, if the Voting Common Stock shall not be so
                  listed or transactions so reported, the average of the bid and
                  asked prices at the end of the day in the over-the-counter
                  market, in each case averaged over a period of 20 consecutive
                  business days prior to the date as of which I, market price"
                  is being determined. If at any time the Voting Common Stock is
                  not listed on any exchange, reported by NASDAQ-NMS or quote in
                  the over-the-counter market, the "market price" shall be
                  deemed to be the higher of (a) the book value thereof as
                  determined by any firm of independent public accountants of
                  recognized standing selected by the Board of Directors of the
                  Corporation as of the last day of any month ending within 60
                  days preceding the date as of which the determination is to be
                  made, or (b) the fair value thereof determined in good faith
                  by the Board of Directors of the Corporation as of a date
                  which is within 15 days of the date as of which the
                  determination is to be made.

                           (7)      Notwithstanding the foregoing right to
                  convert at the option of the holder, each share of Preferred
                  Stock shall automatically be converted into the appropriate
                  number of shares of Voting Common Stock of the corporation in
                  the manner and upon the terms set forth herein, without any
                  act by the corporation or the holders of Preferred Stock,
                  concurrently with the closing of:

                                    (i)   the sale by the corporation of shares
