                             MANSUR INDUSTRIES INC.

                      (PURSUANT TO SECTION 607.0602 OF THE
                        FLORIDA BUSINESS CORPORATION ACT)


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


         Mansur Industries Inc., a corporation organized and existing under the
Business Corporation Act of the State of Florida (hereinafter called the
"Corporation"), hereby certifies that the following resolution was adopted by
the Board of Directors of the Corporation as required by Section 607.0602 of the
Business Corporation Act at a meeting duly called and held on May 1, 2000:

         RESOLVED, that pursuant to the authority granted to and vested in the
Board of Directors of this Corporation (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Articles of
Incorporation of the Corporation, the Board of Directors hereby creates a series
of Preferred Stock, par value $1.00 per share (the "Preferred Stock"), of the
Corporation and hereby states the designation and number of shares, and fixes
the relative rights, preferences, and limitations thereof as follows:

         Series D Convertible Preferred Stock:

         Section 1. DESIGNATION AND AMOUNT. The shares of such series shall be
designated as "Series D Convertible Preferred Stock" (the "Series D Preferred
Stock") and the number of shares constituting the Series D Preferred Stock shall
be 150,000, of which 50,000 shares shall be reserved for use in connection with
the payment of dividends on the outstanding shares of Series D Preferred Stock
pursuant to Section 3 hereof. 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 D Preferred Stock to a number less
than the number of shares then outstanding, plus the number reserved as
aforesaid, and no increase shall increase the number of shares of Series D
Preferred Stock above the total number of authorized shares.






<PAGE>   2

         Section 2. RANK. The Series D Preferred Stock shall rank as to
distributions of assets upon liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary: (i) senior to all of the
Corporation's common stock, par value $.001 per share (the "Common Stock"); (ii)
senior to any class or series of capital stock of the Corporation hereafter
created specifically ranking by its terms junior to the Series D Preferred Stock
(collectively, with the Common Stock, "Junior Securities" or "Junior Stock");
(iii) on parity with the Series B Convertible Preferred Stock, par value $1.00
per share ("Series B Preferred Stock") of the Company; (iv) on parity with the
Series C Convertible Preferred Stock, par value $1.00 per share ("Series C
Preferred Stock") of the Company; and (iv) on parity with any class or series of
capital stock of the Corporation hereafter created specifically ranking by its
terms on parity with the Series B Preferred Stock, Series C Preferred Stock or
Series D Preferred Stock ("Parity Securities" or "Parity Stock"). While any
shares of Series D Preferred Stock are outstanding, no equity securities senior
to the Series D Preferred Stock, as to distribution of assets, payment of
dividends or otherwise ("Senior Securities") or Parity Securities and no
options, warrants or other rights (collectively, "Options") to purchase or
acquire Senior Securities or Parity Securities, or any securities (collectively,
"Convertible Securities") by their terms convertible into or exchangeable for
Senior Securities or Parity Securities, or any Options to purchase or acquire
such Convertible Securities, shall be authorized or issued and (except for
shares issued as dividends on outstanding shares of Series D Preferred Stock) no
additional shares of Series D Preferred Stock, or Options to acquire Series D
Preferred Stock, or Convertible Securities convertible into or exchangeable for
Series D Preferred Stock, or any Option to acquire such Convertible Securities,
shall be issued, in each case, without the approval (by vote or written consent,
as provided by law) of the holders of at least a majority of the then
outstanding shares of Series D Preferred Stock, voting as a single class. This
prohibition shall not include the authorization or issuance of any form of debt
securities or instruments to a bank or other institution.

         Section 3. DIVIDENDS.

                    (a) The dividend rate payable with respect to the
outstanding shares of Series D Preferred Stock ("Dividend Rate") shall be 8.25%
of the Liquidation Value (as defined below) of each share per annum. During the
period commencing on the date of initial issuance of the Series D Preferred
Stock and continuing through the second anniversary of the date thereof, all
such dividends shall be paid by the Corporation, in lieu of cash, through the
issuance of additional shares of Series D Preferred Stock valued at the
Liquidation Value. Thereafter, all such dividends may, at the option of the
Corporation, be paid in lieu of cash, through the issuance of additional shares
of the Series D Preferred Stock, cash legally available for payment thereof, or
any combination of Series D Preferred Stock and cash whether or not such
dividends have been declared. If dividends are paid by the Corporation through
the issuance of additional shares of Series D Preferred Stock and such dividends
would, but for the provisions hereof, be payable with a fractional share, the
Corporation shall pay, in lieu of such fractional share, cash in an amount equal
to the value of such fractional share. Dividends on the Series D Preferred Stock
shall accrue from the date of issuance or thereafter, from the most recent date
on which dividends were payable, and shall be payable semi-annually on June 30
and December 31 of each year (each a "Dividend Payment Date"), commencing on
June 30, 2000; PROVIDED, HOWEVER, that if





                                       2
<PAGE>   3

any such day is a non-business day, the Dividend Payment Date will be the next
business day. Each declared dividend shall be payable to holders of record as
they appear at the close of business on the stock books of the Corporation on
June 10 and December 10 of each year (each of such dates a "Record Date").
Semi-annual dividend periods (each a "Dividend Period") shall commence on and
include the 1st day of July and January of each year and shall end on and
include the day next preceding the next following Dividend Payment Date.

                    (b) No dividends shall be declared or paid or set apart for
payment on any Common Stock, Parity Stock or Junior Stock during any semi-annual
period unless full dividends on the Series D Preferred Stock for all Dividend
Periods ending prior to or during such semi-annual period have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof is set apart for such payment. When dividends are not so paid in
full (or a sum sufficient for such full payment is not so set apart) upon the
Series D Preferred Stock and any other Parity Stock, dividends upon the Series D
Preferred Stock and dividends on such other Parity Stock payable during such
semi-annual period shall be declared pro rata so that the amount of such
dividends so payable per share on the Series D Preferred Stock and such other
Parity Stock shall in all cases bear to each other the same ratio that full
dividends on the shares of Series D Preferred Stock and full dividends, if any,
on shares of such other Parity Stock, bear to each other. If full dividends on
the Series D Preferred Stock have not been declared and paid or set apart for
payment, no dividend or distribution, other than in shares of Junior Stock, may
be declared, set aside or paid on any shares of Junior Stock. Holders of the
Series D Preferred Stock shall not be entitled to any dividends, whether payable
in cash, property or stock, in excess of the dividends provided for herein. No
interest or sum of money in lieu of interest shall be payable in respect of any
declared dividend payment or payments on the Series D Preferred Stock which may
be in arrears. As used herein, the phrase "set apart" in respect of the payment
of dividends shall require deposit of any funds in a bank or trust company in a
separate deposit account maintained for the benefit of the holders of the Series
D Preferred Stock, or, in the case of payment of dividends through the issuance
of shares of the Corporation's Series D Preferred Stock, the deposit of
certificates representing such shares of Series D Preferred Stock with such bank
or trust company.

         Section 4. VOTING RIGHTS. On all matters to come before the
shareholders of the Corporation, the holders of Series D Preferred Stock will
vote together with the holders of the Common Stock, Series B Preferred Stock and
Series C Preferred Stock as a single class, with each share of Series D
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock entitled
to a number of votes equal to the number of shares of Common Stock into which it
is then convertible using the record date for the taking of such vote of
shareholders as the date as of which the Conversion Price (as hereinafter
defined) is calculated except as required by law.

         To the extent that under Florida law or this Certificate of Designation
the vote of the holders of shares of Series D Preferred Stock, voting separately
as a class, is required to authorize a given action of the Corporation, the
affirmative vote or consent of the holders of at least two-thirds of the
outstanding shares of the Series D Preferred Stock shall constitute the approval
of such action by the class. Holders of shares of Series D Preferred Stock shall
be





                                       3
<PAGE>   4

entitled to notice of all shareholder meetings or written consents with respect
to which they would be entitled to vote, which notice shall be provided pursuant
to the Corporation's bylaws and applicable law.

         Section 5. CONVERSION. Subject to and upon compliance with this SECTION
5, the holders of shares of Series D Preferred Stock shall have conversion
rights as follows:

                    (a) OPTIONAL CONVERSION. (i) Each holder of a share of
Series D Preferred Stock shall have the right, at any time or from time to time
prior to the Redemption Date (as defined below), at the office of the
Corporation or any transfer agent for the Series D Preferred Stock, to convert
such share of Series D Preferred Stock into that number of fully paid and
nonassessable shares of Common Stock equal to $100 divided by the Conversion
Price of such share of Series D Preferred Stock as set forth in SECTION 6
hereof. The number of shares of Common Stock into which the Series D Preferred
Stock may be converted is hereinafter referred to as the "Conversion Rate."
Notwithstanding the foregoing, the Corporation shall not be obligated to accept
shares of Series D Preferred Stock for conversion if such conversion would
require the Corporation to issue a certificate or certificates evidencing less
than an aggregate of 50,000 shares of Common Stock on any Date of Conversion (as
defined below).

                        (ii) Without limiting any other rights herein set forth,
if at any time or from time to time prior to the Redemption Date the Corporation
issues any equity security (within the meaning of Section 3(a)(11) of the
Securities Exchange Act of 1934, as amended) or any debt securities convertible
into equity securities, other than Excluded Shares, each holder of a share of
Series D Preferred Stock shall have the right to convert such share of Series D
Preferred Stock into, as the case may be, (A) a number of such fully paid and
nonassessable equity securities determined by dividing $100 by the purchase
price of each such equity security in such transaction or (B) $100 aggregate
principal amount of such convertible debt securities. This right of conversion
shall terminate on the later to occur of (A) the first anniversary of the
issuance of the shares of Series D Preferred Stock and (B) the date on which the
Corporation first consummates the sale of shares of its equity securities or
convertible debt securities for gross cash proceeds to the Corporation of $2.0
million or more, other than Excluded Shares. In the event any holder of a share
of Series D Preferred Stock exercises any right under this subparagraph (ii),
any securities so acquired shall be accompanied by all registration and other
contractual rights, as acquired generally by purchasers of the Corporation's
equity or convertible debt securities in the transaction giving rise to such
rights.

                    (b) EARLY CONVERSION EVENT. If, after the first anniversary
of the date of issuance of the shares of Series D Preferred Stock, the closing
bid price of the Common Stock, as reported on Nasdaq (or the closing sale price
if the Common Stock is then traded on any principal national exchange or Nasdaq
National Market) exceeds 175% of the Conversion Price for a period of twenty
(20) consecutive trading days, including the twenty (20) trading days prior to
such first anniversary (the "Calculation Period"), an early conversion event
("Early Conversion Event") shall have occurred. Upon the first Early Conversion
Event, if any, in each calendar quarter, the aggregate Liquidation Value of the
outstanding shares of Series D Preferred Stock shall automatically and without
any action by the holders of the Series D Preferred





                                       4
<PAGE>   5

Stock or the Corporation be converted into shares of Common Stock, on a pro rata
basis, in an amount determined in accordance with the following formula:

                             CPS = (V x 22 - Y) x CP

where CPS is the aggregate stated Liquidation Value of the Series D Preferred
Stock to be converted; V is the average daily reported volume of trading in the
Common Stock on all national securities exchanges and/or reported through the
automated quotation system of a registered national securities association
during the Calculation Period and Y is the sum of (i) shares of Common Stock
which the Corporation then has the right to issue upon an "Early Conversion
Event" under the Corporation's outstanding 8 1/4% Subordinated Convertible Notes
due 2003 (the "Convertible Notes") or under the Series B Preferred Stock and the
Series C Preferred Stock, plus (ii) shares of Common Stock subject to then
effective resale registration statements of the Corporation other than
Registration Statements on Form S-8 or S-4 and other than registration
statements with respect to Common Stock underlying the Convertible Notes, the
Series B Preferred Stock, the Series C Preferred Stock and Series D Preferred
Stock which remain unsold at such time, plus (iii) shares of Common Stock
issuable upon exercise of the Warrants; and CP is the applicable Conversion
Price. For purposes of calculating V, trading volume in excess of 100,000 shares
on any trading day shall not be included, unless such amounts do not exceed 200%
of the trailing 30-day average reported volume of trading.

         Notwithstanding the foregoing, none of the outstanding shares of Series
D Preferred Stock shall be converted as a result of an Early Conversion Event
pursuant to this SECTION 5 unless the resale of the shares of Common Stock
issuable upon such conversion is subject to an effective Registration Statement
under the Securities Act of 1933, as amended (the "Securities Act"), or an
exemption from registration under the Securities Act is then available. Accrued
dividends on the shares of Series D Preferred Stock converted upon the
occurrence of an Early Conversion Event shall be paid on the next Dividend
Payment Date in accordance with SECTION 3 hereof.

                    (c) MECHANICS OF CONVERSION. Before a holder shall be
entitled to receive shares of Common Stock or other securities of the
Corporation upon conversion of shares of Series D Preferred Stock, the holder of
shares of Series D Preferred Stock shall (i) fax or otherwise deliver a copy of
the fully executed notice of conversion in the form attached hereto as EXHIBIT A
("Notice of Conversion") to the Corporation at its principal office and to the
office of its designated transfer agent that such holder elects to convert the
same, which notice shall specify the number of shares of Series D Preferred
Stock to be converted and shall contain the Conversion Price (together with a
copy of the first page of each certificate to be converted) prior to 5:00 p.m.,
Eastern Standard time (the "Conversion Notice Deadline") on the date of
conversion specified on the Notice of Conversion and (ii) surrender the original
certificate or certificates for the shares of Series D Preferred Stock to be
converted, duly endorsed, and deliver the original Notice of Conversion by
either overnight courier or two-day courier, to the principal office of the
Corporation or to the office of its designated transfer agent; PROVIDED,
HOWEVER, that





                                       5
<PAGE>   6

the Corporation shall not be obligated to issue certificates evidencing the
shares of Common Stock or other securities of the Corporation issuable upon such
conversion unless the certificates evidencing such shares of Series D Preferred
Stock are delivered to the Corporation or its transfer agent as provided above.
Upon the conversion of shares of Series D Preferred Stock in connection with an
Early Conversion Event, the Corporation shall send to the holders of shares of
Series D Preferred Stock a Notice of Early Conversion (in the form attached
hereto as EXHIBIT B) stating the aggregate Liquidation Value of shares of Series
D Preferred Stock to be converted and the number of shares of Common Stock into
which such Liquidation Value shall be converted.

         Upon receipt by the Corporation of evidence of the loss, theft,
destruction or mutilation of any certificate representing shares of Series D
Preferred Stock, and (in the case of loss, theft or destruction) of indemnity or
security reasonably satisfactory to the Corporation, and upon surrender and
cancellation of any certificate representing shares of Series D Preferred Stock,
if mutilated, the Corporation shall execute and deliver a new certificate of
like tenor and date. No fractional shares of Common Stock or other securities of
the Corporation shall be issued upon conversion of the Series D Preferred Stock.
In lieu of any fractional share to which the holder of shares of Series D
Preferred Stock would otherwise be entitled, the Corporation shall pay cash to
such holder in an amount equal to such fraction multiplied by the Conversion
Price then in effect. In the case of a dispute as to the calculation of the
Conversion Price, the Corporation's calculation shall be deemed conclusive
absent manifest error.

         The Corporation shall use all reasonable efforts to issue and deliver
within seven (7) business days after delivery to the Corporation of the
certificates representing the shares of Series D Preferred Stock to be
converted, or after such agreement and indemnification, to such holder of shares
of Series D Preferred Stock at the address of the holder on the books of the
Corporation, a certificate or certificates for the number of shares of Common
Stock or other securities of the Corporation to which the holder shall be
entitled as aforesaid. The date on which conversion occurs (the "Date of
Conversion") shall be deemed to be the date set forth in such Notice of
Conversion, provided (i) that the advance copy of the Notice of Conversion is
delivered to and received by the Corporation before 5:00 p.m., Eastern time, on
the Date of Conversion, and (ii) that the original stock certificates
representing the shares of Series D Preferred Stock to be converted are received
by the Corporation or the transfer agent within two (2) business days
thereafter. In the case of an Early Conversion Event, the last date of the
Calculation Period shall be deemed to be the Date of Conversion. The person or
persons entitled to receive the shares of Series D Preferred Stock issuable upon
such conversion shall be treated for all purposes as the record holder or
holders of such shares of Common Stock or other securities of the Corporation on
the Date of Conversion. In the case of an optional conversion, if the original
certificates representing the shares of Series D Preferred Stock to be converted
are not received by the Corporation or the transfer agent within two (2)
business days after the Date of Conversion or if the facsimile of the Notice of
Conversion is not received by the Corporation or its transfer agent prior to the
Conversion Notice Deadline, the Notice of Conversion, at the Corporation's
option, may be declared null and void.




                                       6
<PAGE>   7

         Following any conversion of shares of Series D Preferred Stock, such
shares of Series D Preferred Stock shall no longer be outstanding and all rights
of a holder with respect to the shares surrendered for conversion shall
immediately terminate except for the right to receive Common Stock or other
securities of the Corporation. All shares of Series D Preferred Stock subject to
an Early Conversion Event shall be deemed to be cancelled upon such holder's
receipt of shares of Common Stock or other securities of the Corporation in
connection with any such conversion.

                    (d) RESERVATION OF SHARES. The Corporation shall at all
times reserve and keep available out of its authorized but unissued shares of
Common Stock or other securities of the Corporation such number of shares of
Common Stock or other securities as shall from time to time be sufficient to
effect the conversion of all then outstanding shares of Series D Preferred
Stock; and if at any time the number of authorized but unissued shares of Common
Stock or other securities shall not be sufficient to effect the conversion of
all then outstanding shares of Series D Preferred Stock, the Corporation will
take such corporate action as may be necessary to increase its authorized but
unissued shares of Common Stock or other securities of the Corporation to such
number of shares as shall be sufficient for such purpose.

                    (e) NOTICE OF CERTAIN EVENTS. The Corporation shall deliver
written notice to each holder of Series D Preferred Stock at each issuance of
equity securities or convertible debt securities giving rise to a right under
paragraph (a)(ii) immediately preceding at least 30 days prior to the
consummation thereof, describing in reasonable detail the pertinent transaction.

         Section 6. CONVERSION PRICE. The "Conversion Price" per share of the
Series D Preferred Stock shall be $5.50, subject to adjustment as set forth
below, with all such adjustments, if any, being cumulative from the date of
initial issuance of shares of Series D Preferred Stock such that all outstanding
shares of Series D Preferred Stock have the same Conversion Price regardless of
their date of issuance.

                 6.1 ADJUSTMENT OF THE NUMBER OF SHARES OF COMMON STOCK AND THE
CONVERSION PRICE. The number of shares of Common Stock issuable upon conversion
and the Conversion Price shall be subject to adjustment as follows:

                    (a) In case the Corporation shall at any time after the date
of the initial issuance of Series D Preferred Stock and prior to the conversion
of all outstanding shares thereof (A) pay a dividend or make a distribution on
its Common Stock in shares of its capital stock (whether in shares of Common
Stock, of capital stock of any other class or Options to purchase or acquire
capital stock, Convertible Securities convertible or exchangeable for capital
stock, or Options with respect to such Convertible Securities), (B) subdivide
its outstanding shares of Common Stock into a greater number of shares, (C)
combine its outstanding shares of Common Stock into a smaller number of shares,
or (D) reclassify, reorganize or effect any similar transaction with respect to
any of its shares of Common Stock, or in substitution or exchange therefor
(other than a change in par value, or from par value to no par value, or from no
par value





                                       7
<PAGE>   8

to par value), then the number and, if applicable, kind of shares of Common
Stock to be received by any holder of shares of Series D Preferred Stock (a
"Holder") shall be adjusted so that the Holder will be entitled to receive on
conversion the number and kind of shares of capital stock or other securities
which it would have owned immediately following such action had its Series D
Preferred Stock been converted immediately prior thereto. An adjustment made
pursuant to this subsection (a) shall become effective immediately after the
payment date in the case of a dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision,
combination, reclassification, reorganization or similar transaction. If, as a
result of an adjustment made pursuant to this subsection (a), a Holder shall
become entitled to receive shares of two or more classes of capital stock of the
Corporation or other securities, the Board of Directors or a duly authorized
committee thereof shall in good faith determine (which determination shall be
conclusive and binding) the allocation of the Conversion Price between or among
shares of such classes of capital stock or other securities. After such
allocation, the Conversion Price and number of shares of each class of capital
stock that is issuable upon conversion shall thereafter be subject to adjustment
in a manner and on terms determined by the Board of Directors (which
determination shall be conclusive and binding) to be as nearly equivalent as
practicable to those applicable to Common Stock under this Section 6.

                    (b) (i) From the date of the initial issuance of shares of
Series D Preferred Stock until the later of (A) the first anniversary of the
date of such issuance and (B) the date on which the Corporation first
consummates a sale of equity securities or debt securities convertible into
equity securities for gross cash proceeds to the Company of $2.0 million or more
(such period through such later date, the "Reset Period"), other than Excluded
Shares (as hereinafter defined), if the Corporation shall issue or enter into
any agreement to issue any shares of Common Stock other than Excluded Shares for
consideration per share (the "Issuance Price") less than the Conversion Price
(as herein defined) per share in effect immediately prior to such issuance, the
Conversion Price in effect immediately prior to such issuance shall be reduced
(but shall not be increased) to the Issuance Price.

                        (ii) If, at any time subsequent to the Reset Period and
prior to the first anniversary of the expiration of the Reset Period, the
Corporation shall issue or enter into any agreement to issue any shares of
Common Stock other than Excluded Shares for consideration per share less than
the Conversion Price per share in effect immediately prior to such issuance, the
Conversion Price in effect immediately prior to such issuance shall be reduced
(but shall not be increased) to the price (calculated to the nearest cent)
determined: by dividing (A) an amount equal to the sum of (1) the number of
shares of Common Stock outstanding on a fully diluted basis immediately prior to
such issuance multiplied by the Conversion Price per share in effect immediately
prior to such issuance and (2) the consideration, if any, received by the
Corporation upon such issuance by (B) the number of shares of Common Stock
outstanding on a fully diluted basis immediately after such issuance.

                        (iii) If, at any time from the date of the initial
issuance of shares of Series D Preferred Stock, prior to the first anniversary
of the expiration of the Reset Period, the Corporation shall issue or enter into
any agreement to issue any shares of Common Stock





                                       8
<PAGE>   9

other than Excluded Shares for consideration per share greater than the
Conversion Price but lower than the market price per share in effect immediately
prior to such issuance, the Conversion Price in effect immediately prior to such
issuance shall be reduced (but shall not be increased) to the price (calculated
to the nearest cent) determined by multiplying the Conversion Price in effect
immediately prior to such issuance by the factor determined by dividing (A) an
amount equal to the sum of (1) the number of shares of Common Stock outstanding
on a fully diluted basis immediately prior to such issuance multiplied by the
market price per share in effect immediately prior to such issuance and (2) the
consideration, if any, received by the Corporation upon such issuance by (B) the
number of shares of Common Stock outstanding on a fully diluted basis
immediately after such issuance multiplied by the market price per share in
effect immediately prior to such issuance; PROVIDED, HOWEVER, no adjustment
shall be made to the Conversion Price if (i) such issuance is in connection with
a firm commitment underwritten public offering or (ii) the consideration per
share is equal to or greater than 85% of the market price per share in effect
immediately prior to such issuance. For purposes hereof, the "market price" as
of any measurement date shall be the average of the closing prices of the Common
Stock for each of the 10 consecutive trading days immediately preceding such
measurement date.

                    (c) CERTAIN ADJUSTMENT FACTORS. For the purposes of any
adjustment of the Conversion Price pursuant to paragraph (b) above, the
following provisions shall be applicable:

                                        (X) CASH. In the case of the issuance of
                    shares of Common Stock for cash, the amount of the
                    consideration received by the Corporation shall be deemed to
                    be the amount of the cash proceeds received by the
                    Corporation for such shares of Common Stock before deducting
                    therefrom any discounts, commissions, taxes or other
                    expenses allowed, paid or incurred by the Corporation for
                    any underwriting or otherwise in connection with the
                    issuance and sale thereof; and

                                        (Y) CONSIDERATION OTHER THAN CASH. In
                    the case of the issuance of shares of Common Stock (other
                    than upon the conversion of shares of capital stock or other
                    securities of the Corporation) for consideration in whole or
                    in part other than cash, including securities acquired in
                    exchange therefor (other than securities by their terms so
                    exchangeable), the consideration other than cash shall be
                    deemed to be the fair value thereof (as determined by the
                    Board of Directors of the Corporation based on an opinion of
                    an outside financial advisor of recognized regional or
                    national standing, which may, but need not, be the
                    independent public accountants who serve as the regular
                    auditors of the Corporation (the "Financial Advisor"), whose
                    determination shall be conclusive and binding), irrespective
                    of any accounting treatment; and

                                        (Z) OPTIONS AND CONVERTIBLE SECURITIES.
                    In the case of the issuance of (i) Options to purchase or
                    acquire shares of Common Stock (whether or not exercisable
                    immediately following such issuance), (ii) Convertible






                                       9
<PAGE>   10

                    Securities by their terms convertible into or exchangeable
                    for shares of Common Stock (whether or not so convertible or
                    exchangeable immediately following such issuance), or (iii)
                    Options to purchase such Convertible Securities (whether or
                    not exercisable immediately following such issuance):

                                        (1) the aggregate maximum number of
                              shares of Common Stock deliverable upon exercise
                              of such Options to purchase or acquire shares of
                              Common Stock shall be deemed to have been issued
                              at the time such Options are first issued and for
                              a consideration equal to the consideration
                              (determined in the manner provided in clauses (x)
                              and (y) above), if any, received by the
                              Corporation upon the issuance of such Options plus
                              the purchase price provided in such Options for
                              the shares of Common Stock covered thereby (if the
                              purchase price per share of Common Stock is
                              expressed as a range, the purchase price per share
                              for purposes of this subparagraph (z)(1) shall be
                              the average of such range of prices);

                                        (2) the aggregate maximum number of
                              shares of Common Stock deliverable upon conversion
                              of or in exchange for any such Convertible
                              Securities, or upon the exercise of Options to
                              purchase or acquire such Convertible Securities
                              and the subsequent conversion or exchange thereto
                              shall be deemed to have been issued at the time
                              such convertible or exchangeable securities or
                              such options, warrants or other rights are first
                              issued and for a consideration equal to the
                              consideration, if any, received by the Corporation
                              for any such Convertible Securities or Options
                              (excluding any cash received on account of accrued
                              interest or accumulated dividends), plus the
                              additional consideration, if any, to be received
                              by the Corporation upon the conversion or exchange
                              of such Convertible Securities and the exercise of
                              any Options (the consideration in each case to be
                              determined in the manner provided in clauses (x)
                              and (y) above);

                                        (3) on any change in the number of
                              shares of Common Stock deliverable upon exercise
                              of any such Options which have become exercisable
                              or conversion of or exchange of such Convertible
                              Securities which have become convertible or
                              exchangeable, or any change in the consideration
                              to be received by the Corporation upon such
                              exercise, conversion or exchange, the Conversion
                              Price as then in effect shall forthwith be
                              readjusted to such Conversion Price as would have
                              been obtained had such adjustment been made upon
                              the original issuance of such Options; provided,
                              however, no adjustment shall be made with respect
                              to such Options exercised prior to such change, or
                              Convertible Securities converted or exchanged
                              prior to such change;





                                       10

                                        (4) on the expiration or cancellation of
                              any such Options or the termination of the right
                              to convert or exchange such Convertible
                              Securities, if the Conversion Price shall have
                              been adjusted upon such securities being issued or
                              becoming exercisable, convertible or exchangeable,
                              such Conversion Price shall forthwith be
                              readjusted to such Conversion Price as would have
                              been obtained had an adjustment been made on the
                              basis of the issuance of only the number of shares
                              of Common Stock actually issued upon the exercise
                              of such options, warrants or other rights, or upon
                              the conversion or exchange of such securities; and

                                        (5) if the Conversion Price shall have
                              been adjusted when such Options were first issued
                              or such Convertible Securities were first issued,
                              no further adjustment of the Conversion Price
                              shall be made for the actual issuance of shares of
                              Common Stock upon the exercise, conversion or
                              exchange thereof.

                    (d) EXCLUDED SHARES. "Excluded Shares" shall mean (i) any
shares of Common Stock issued in a transaction described in Section 6.1(a) of
this Agreement; (ii) issuances of shares of Common Stock from time to time
pursuant to employment agreements, stock option or bonus plans authorized by the
Board of Directors of the Corporation as of the date hereof, (iii) issuances of
Common Stock, or Options to acquire shares of Common Stock, or Convertible
Securities convertible into or exchangeable for Common Stock pursuant to the
terms of any acquisition by the Corporation of all or substantially all of the
operating assets, or more than fifty percent (50%) of the voting capital stock
or other controlling interest of any business entity in a transaction negotiated
on an arms-length basis and expressly approved in advance by the Board of
Directors of the Corporation; (iv) issuances of shares of Common Stock from time
to time upon the exercise, exchange or conversion of warrants, options,
convertible securities, the Convertible Notes or other securities outstanding as
of the date hereof and pursuant to the written terms of such securities as they
exist as of the date hereof and (v) issuances of shares of Common Stock from
time to time pursuant to the anti-dilution provisions of other securities. For
purposes hereof, "voting capital stock" shall be deemed to be capital stock of
any class or classes, however designated having ordinary voting power for the
election of members of the board of directors or other governing body and
"controlling" shall mean the possession, directly or indirectly, of the power to
direct or cause the direction of the management and policies of a party, whether
through the ownership of voting capital stock, by contract or otherwise.

                    (e) For further clarity, any change to the conversion price
or other terms of the 8 1/4% Subordinated Convertible Notes Due 2003 shall not
count toward determining the Reset Period, but shall, notwithstanding any other
provision herein, be taken into account in determining whether any adjustment to
the Conversion Price is due under this Section 6.1.

                    (f) No adjustment in the Conversion Price shall be required
unless such adjustment would require an increase or decrease of at least 1.2% in
such price; PROVIDED, HOWEVER, that any adjustments which by reason of this
subsection (e) are not required to be made





                                       11
<PAGE>   12

shall be carried forward and taken into account in any subsequent adjustment.
All calculations under this Section 6 shall be made to the nearest tenth of a
cent or to the nearest one-hundredth of a share, as the case may be.

                    (g) The number of shares of Common Stock outstanding at any
given time shall not include shares owned or held by or for the account of the
Corporation, and the disposition of any such shares shall be considered an
issuance of Common Stock for the purposes of this Section 6.

         6.2 RIGHTS TO PURCHASE OTHER SECURITIES. If any of the following shall
occur:

         Without limiting any provisions of Section 9:

                    (a) any Corporate Change (as hereinafter defined) to which
the Corporation is a party, other than a Corporate Change in which the
Corporation is the continuing or surviving Corporation and which does not result
in any reclassification of, or change (other than as a result of a subdivision
or combination) in, outstanding shares of the Common Stock, or

                    (b) any sale or transfer to another corporation or entity of
all or substantially all of the assets of the Corporation; then, and in either
such case, the Holder of each share of Series D Preferred Stock then outstanding
shall have the right to purchase the kind and amount of shares of stock and/or
other securities and property receivable upon such consolidation, merger, sale
or transfer by a holder of the number of shares of Common Stock issuable upon
conversion of such stock immediately prior to such consolidation, merger, sale,
or transfer. The provisions of this Section 6.2 shall similarly apply to
successive consolidations, mergers, sales or transfers.

         6.3 NOTICE OF ADJUSTMENT. Whenever the number of shares of Common Stock
issuable upon the conversion of each share of Series D Preferred Stock or the
Conversion Price of such shares of Series D Preferred Stock, or the Conversion
Price, is adjusted or reduced, as herein provided, the Corporation shall mail by
first class, postage prepaid, to each Holder (a) notice of any reduction on or
before the day the reduction takes effect, which shall state the reduced
Conversion Price and the period during which it will be in effect and/or (b) a
certificate setting forth the number of shares of Common Stock issuable upon the
conversion of each share of Series D Preferred Stock and the Conversion Price on
such shares of Series D Preferred Stock after adjustment setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. The Corporation shall further
deliver notice to each Holder, in the manner aforesaid, of the expiration of the
Reset Period.

         6.4 NO ADJUSTMENT FOR DIVIDEND. No adjustment in respect of any cash
dividends shall be made while the Series D Preferred Stock is outstanding or
upon the conversion of the Series D Preferred Stock.

         6.5 CERTAIN EVENTS. If any event occurs as to which in the reasonable
judgment of the Board of Directors of the Corporation , in good faith, the other
provisions of this Section 6 are not strictly applicable but the lack of any
adjustment would not in the opinion of the Board of Directors of the Corporation
fairly reflect the purchase rights of the Holders of the Series D Preferred
Stock in accordance with the basic intent and principles of the provisions of
this Agreement then the Board of Directors of the Corporation shall appoint a
Financial Advisor which shall give its opinion upon the adjustment, if any, on a
basis consistent with the basic intent and principles established and the other
provisions of this Section 6, necessary to preserve, without dilution, the
exercise rights of the Holders. Upon receipt of such opinion, the Corporation
shall forthwith make the adjustments described therein which adjustments shall
be conclusive and binding. Without limiting the generality of the foregoing
provisions of this Section 6.5, in the event any holder of Series D Preferred
Stock becomes entitled under Section 5(a)(ii) hereof to convert any share
thereof into any securities of the Corporation other than Common Stock: (i) the
number and kind of such securities shall be subject thereafter to modification
pursuant to comparable principles to those applicable under this Section 6 to
the Common Stock; (ii) the purchase price in such conversion shall be subject to
modification pursuant to comparable principles to those applicable under this
Section 6 to the Conversion Price; and (iii) any and all notices under this
Section 6 applicable to modifications in the Conversion Price or the securities
issuable upon conversion of the Series D Preferred Stock shall apply MUTATIS
MUTANDIS to modifications in the rights under Section 5(a)(ii) hereof, in each
case under clauses (i), (ii) and (iii) immediately preceding, so as to preserve
without dilution, the rights of the Holders.

         Section 7. STATUS OF CONVERTED OR REACQUIRED SHARES. Any shares of
Series D Preferred Stock converted into shares of Common Stock pursuant to
SECTION 5 hereof or purchased or otherwise acquired by the Corporation in any
manner whatsoever shall be retired and canceled promptly after the conversion or
acquisition thereof. All such shares shall upon their cancellation become
authorized but unissued shares of Series D 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 Certificate of Designation creating a series of preferred stock or
any similar stock or as otherwise required by law.

         Section 8. LIQUIDATION, DISSOLUTION OR CHANGE OF CONTROL.

                    (a) In the event of any liquidation, dissolution or winding
up of the Corporation, either voluntary or involuntary, the holders of shares of
Series D Preferred Stock shall be entitled to receive out of the assets of the
Corporation available for distribution to shareholders under applicable law,
prior and in preference to any distribution to holders of the Common Stock or
any Junior Securities but in parity with any distribution to holders of Parity
Securities, an amount of $100 per share (the "Liquidation Value"), plus a sum
equal to all dividends accrued on such shares (whether or not declared) and
unpaid through and including the then current Dividend Period. If upon the
occurrence of such event, the assets and funds to be distributed among the
holders of shares of Series B Preferred Stock, Series C Preferred Stock,





                                       13
<PAGE>   14

Series D Preferred Stock and Parity Securities shall be insufficient to permit
the payment to such holders of the full preferential amounts due to the holders
of shares of Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock and Parity Securities, respectively, then the entire assets and
funds of the Corporation legally available for distribution shall be distributed
among the holders of shares of Series B Preferred Stock, Series C Preferred
Stock and Parity Securities, pro rata, based on the respective liquidation
amounts to which each such series of stock is entitled by the Corporation's
Articles of Incorporation and any certificate of designation of preferences.

                    (b) Upon the completion of the distribution required by
subsection 8(a) above, if assets remain in the Corporation, they shall be
distributed to holders of Parity Securities (unless holders of Parity Securities
have received distributions pursuant to subsection 8(a)) and Junior Securities
in accordance with the Corporation's Articles of Incorporation, including any
duly adopted certificate(s) of designation of preferences.

                    (c) (i) Upon a Change of Control (as defined below) of the
Corporation, each holder of the Series D Preferred Stock will have the option to
require the Corporation to repurchase such holder's shares of Series D Preferred
Stock at a price per share equal to the Liquidation Value plus any accrued and
unpaid dividends. A "Change of Control" shall have occurred: (A) when any person
or group is or becomes the beneficial owner of 50% or more of the then
outstanding voting capital stock of the Corporation, (B) when, during any period
of two consecutive years after the closing of the sale of the Series D Preferred
Stock, individuals who at the beginning of such period constituted the
Corporation's Board of Directors, or whose nomination for election by the
Corporation's shareholders was approved by a vote of a majority of the directors
of the Corporation then still in office who were either directors at the
beginning of such period or whose election or nomination for election was
previously so approved, cease for any reason to constitute a majority of the
directors then in office or (C) upon any sale, transfer or other conveyance of
all or substantially all of the assets of the Corporation.

                        (ii) Upon the occurrence of a Change of Control, the
Corporation will offer to repurchase (the "Change of Control Purchase Offer")

                    Preferred Stock at the price set forth above;

                                        (B) the circumstances and relevant facts

                    will repurchase any shares of Series D Preferred Stock which
                    the holders require the Corporation to repurchase in
                    accordance with this subsection 8(c), which date shall be no
                    earlier than 30 days nor later than 60 days from the date
                    such Change of Control Notice is mailed (the "Change of
                    Control Purchase Date");

                                        (D) that, unless the Corporation
                    defaults in making such payment, any shares of Series D
                    Preferred Stock accepted for payment pursuant to the Change
                    of Control Purchase Offer shall cease to accrue dividends

                                        (E) that holders of Series D Preferred
                    Stock electing to have their shares repurchased pursuant to
                    any Change of Control Purchase Offer shall be required to
                    surrender the original certificates for the shares of Series
                    D Preferred Stock at the address specified in the notice, at
                    least three business days before the Change of Control
                    Purchase Date; and

                                        (F) that the holders of Series D
                    Preferred Stock shall be entitled to withdraw their election
                    if the Corporation receives, not later than the last
                    business day prior to the Change of Control Purchase Date, a
                    telegram, telex, facsimile transmission or letter setting
                    forth the name of the holder, the number of shares of Series
                    D Preferred Stock the holder delivered for repurchase and a
                    statement that such holder is withdrawing his election to
                    have such shares repurchased.

                        (iii) Each holder of shares of Series D Preferred Stock
electing to have such shares purchased by the Corporation pursuant to this
subsection 8(c) shall deliver to the Corporation at its principal office, at
least three business days prior to the Change of Control Purchase Date, the
original certificate or certificate(s) for the shares to be purchased duly
endorsed, together with written notice to the Corporation specifying the number
of shares of Series D Preferred Stock to be purchased. Holders of Series D

receives, not later than one business day prior to the Change of Control
Purchase Date, a telegram, facsimile transmission or letter, at its principal
office, setting forth the name of the holder, the number of shares of Series D
Preferred Stock which were delivered by the holder for purchase by the
Corporation and a statement that such holder is withdrawing his election to have
such shares purchased.

                        (iv) Promptly following the Change of Control Purchase
Date, the Corporation will mail or deliver to each holder of shares of Series D
Preferred Stock who properly tendered such shares to the Corporation for
purchase pursuant to this subsection 8(c) and did not withdraw such election, at
his, her or its address of record, an amount equal to the purchase price for the
shares of Series D Preferred Stock so delivered for purchase as set forth in
this subsection 8(c). Unless the Corporation shall have defaulted in the payment
of the purchase





                                       15
<PAGE>   16

price for shares of Series D Preferred Stock tendered for purchase by the
Corporation, all rights of the holders of such shares (except the right to
receive the purchase price therefor) shall cease with respect to such shares on
the Change of Control Purchase Date and such shares shall not, after the Change
of Control Purchase Date, be deemed to be outstanding and shall not have the
status of Series D Preferred Stock.

                    (v) The Corporation will comply, to the extent applicable,
with the requirements of Section 14(e) of the Securities Exchange Act of 1934,
as amended, and any other applicable securities laws or regulations in
connection with the repurchase of Series D Preferred Stock pursuant to this
subsection 8(c). To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this subsection 8(c), the
Corporation will comply with the applicable securities laws and regulations and
will not be deemed to have breached its obligations under this Section by virtue
thereof.

         Section 9. CONSOLIDATION, MERGER, ETC. Except as set forth in Section
8(c) hereof, and without limiting any provision of Section 6.2 hereof, in the
event of a merger, reorganization, recapitalization or similar event of or with
respect to the Corporation (a "Corporate Change") (other than a Corporate Change
in which all or substantially all of the consideration received by the holders
of the Corporation's equity securities upon such Corporate Change consists of
cash or assets other than securities issued by the acquiring entity or any
Affiliate thereof), the Series D Preferred Stock shall be assumed by the
acquiring entity and thereafter the Series D Preferred Stock shall be
convertible into such class and type of securities as the holder of shares of
Series D Preferred Stock would have received had such holder converted the
Series D Preferred Stock immediately prior to such Corporate Change.

         Section 10. REDEMPTION.

                    (a) OPTIONAL REDEMPTION. Subject to earlier conversion,
commencing on May 17, 2002 and continuing through the Mandatory Redemption Date
(as defined below), the Corporation shall have the right, exercisable at any
time and from time to time, to redeem shares of Series D Preferred Stock at the
following prices plus the payment of all accrued and unpaid dividends:

                           Year Redeemed                 Price
                           -------------                 -----
                               2002            104% of Liquidation Value

                               2003            102% of Liquidation Value

         If less than all of the outstanding shares of Series D Preferred Stock
are called for redemption pursuant to this SECTION 10(A), shares of Series D
Preferred Stock shall be redeemed on a pro rata basis among the holders thereof.
Each holder of Series D Preferred Stock will be given notice of such redemption
pursuant to Section 10(c) and will have the right to





                                       16
<PAGE>   17

convert the Series D Preferred Stock into shares of Common Stock prior to the
redemption date specified in such notice.

                    (b) MANDATORY REDEMPTION.

                        (i) The Corporation will be required to redeem the
outstanding shares of Series D Preferred Stock on May 17, 2004 (the "Mandatory
Redemption Date"), at a redemption price per share equal to the Liquidation
Value plus accrued and unpaid dividends.

                        (ii) If at any time, (A) the Corporation shall breach
the terms and conditions contained in this certificate of designation, (B) the
Corporation shall breach any representation, warranty, or covenant contained in
that certain Series D Convertible Stock and Warrant Purchase Agreement, dated
May __, 2000, between the Corporation and the initial Holders or any subsequent
Series D Stock Purchase Agreement with like terms, or (C) the Corporation shall
fail to make a dividend payment on a Dividend Payment Date (each a "Breach"),
prompt notice of such Breach shall be given to each Holder by the Corporation at
such time as the Corporation becomes aware of such Breach and (without limiting
any rights of Holder) prompt notice of such Breach shall be given to the
Corporation by each Holder at such time such Holder becomes aware of such
Breach, and any Holder shall give written notice to the Corporation of its
desire to have the Corporation redeem its shares of Series D Preferred Stock,
such shares shall be redeemed by the Corporation at a redemption price per share
equal to the greater of the amounts that would at that time be payable under
Section 10(a) hereof had the Corporation exercised its right to redeem the
shares of Series B Preferred Stock thereunder or the Liquidation Value plus
accrued and unpaid dividends; PROVIDED, HOWEVER, no Holder shall have the right
to request a redemption of its shares of Series D Preferred Stock pursuant to
this SECTION 10(B)(II) unless and until the Corporation shall have failed to
cure any such Breach within a period of ten (10) days after having received
written notice thereof from the Holder.

                    (c) MECHANICS OF REDEMPTION. Notice of redemption of the
Series D Preferred Stock, specifying the redemption date and place of
redemption, shall be given by first class mail to each holder of record of the
shares to be redeemed, at his address of record, not less than 30 nor more than
60 calendar days prior to the date upon which the Corporation shall redeem the
Series D Preferred Stock (the "Redemption Date"). Each such notice shall also
specify the redemption price applicable to the shares to be redeemed. If less
than all the shares owned by such holder are then to be redeemed, the notice
shall also specify the number of shares thereof which are to be redeemed and the
fact that a new certificate or certificates representing any unredeemed shares
shall be issued without cost to such holder.

                        (i) Notice of redemption of shares of the Series D
Preferred Stock having been given as provided in SECTION 10(c), then unless the
Corporation shall have defaulted in the payment of the redemption price and all
accrued and unpaid dividends (whether or not declared), all rights of the
holders thereof (except the right to receive the redemption price and all
accrued and unpaid dividends, whether or not declared) shall cease with respect
to such shares on the Redemption Date and such shares shall not, after the
Redemption Date, be deemed





                                       17
<PAGE>   18

to be outstanding and shall not have the status of Series D Preferred Stock. In
case fewer than all the shares represented by any such certificate are redeemed,
a new certificate shall be issued representing the unredeemed shares without
cost to the holder thereof.

                        (ii) Shares of the Series D Preferred Stock are not
subject or entitled to the benefit of a sinking fund.

                        (iii) Notwithstanding the foregoing, if notice of
redemption shall have been given pursuant to this SECTION 10 and any holder of
the Series D Preferred Stock shall, prior to the close of business on the date
three business days next preceding the Redemption Date, give written notice to
the Corporation pursuant to SECTION 5 hereof of the conversion of any or all of
the shares held by the holder (accompanied by a certificate or certificates for
such shares, duly endorsed or assigned to the Corporation), then the redemption
shall not become effective as to such shares and the conversion shall become
effective as provided in SECTION 5.

                        (iv) If on the Mandatory Redemption Date funds legally
available to the Corporation for redemption of all outstanding shares of Series
B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock are
insufficient to redeem all such shares of Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock, such available funds shall be used
by the Corporation to redeem shares of Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock from all holders ratably in
proportion to the full number of shares they would otherwise be entitled to have
redeemed. In the event that less than all outstanding shares of Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock are
redeemed on the Mandatory Redemption Date, the Corporation will continue to
redeem shares of Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock from time to time as soon as practicable after funds become
legally available therefor (ratably if the funds legally available remain
insufficient to redeem all shares required to be redeemed) until all shares of
Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock
required to be redeemed shall have been redeemed. Until actually redeemed, each
share of Series D Preferred Stock will continue to enjoy all rights and benefits
hereof, including the right to convert into shares of Common Stock.

                    (d) CONVERSION PRICE ADJUSTMENT FOR FAILURE TO REDEEM. If
the Corporation fails to redeem all outstanding shares of Series D Preferred
Stock on the Mandatory Redemption Date, then, without any action by the holders
of shares of Series D Preferred Stock, the then current Conversion Price
respecting any shares of Series D Preferred Stock not redeemed by the
Corporation shall be reduced (but shall not be increased) to the greater of: (i)
fifty percent (50%) of the then current Conversion Price, and (ii) the closing
price of the Common Stock as reported by Nasdaq (or such principal national
exchange on which the Common Stock is then listed) on the Mandatory Redemption
Date.

          Section 11. AMENDMENT. The Articles of Incorporation of the
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or





                                       18
<PAGE>   19

special rights of the Series D Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of at least two-thirds of the
outstanding shares of Series D Preferred Stock, voting together as a single
class.

         Section 12. NOTICES. Written notice of each meeting of the shareholders
of the Corporation shall be given by first-class mail not less than ten (10)
days prior to such meeting to each holder of record of the Series D Preferred
Stock to the address of such record holder shown on the Corporation's records.

         Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of this Warrant, and (in the case
of loss, theft or destruction) of reasonably satisfactory indemnification, and
upon surrender and cancellation of this Warrant, if mutilated, the Company shall
execute and deliver a new Warrant of like tenor and date. Any such new Warrant
executed and delivered shall constitute an additional contractual obligation on
the part of the Company, whether or not this Warrant so lost, stolen, destroyed
or mutilated shall be at any time enforceable by anyone.

         The Holder agrees with the Company that this Warrant is issued, and all
the rights hereunder shall be held subject to, all of the conditions,
limitations and provisions set forth herein.

         1.       EXERCISE OF WARRANT.

                  1.1 CASH EXERCISE. This Warrant may be exercised, in whole or
in part, at any time, or from time to time during the period commencing on the
date hereof and expiring 5:00 p.m. Eastern Time on May _____, 2005 (the
"Expiration Date"), by presentation and surrender of this Warrant to the Company
at its principal office, or at the office of its stock transfer agent, if any,
with the Warrant Exercise Form attached hereto duly executed and accompanied by
payment (either in cash or by certified or official bank check, payable to the
order of the Company) of the Exercise Price for the number of shares specified
in such form and instruments of transfer, if appropriate, duly executed by the
Holder or his or her duly authorized attorney. If this Warrant should be
exercised in part only, the Company shall, upon surrender of this Warrant for
cancellation, execute and deliver a new Warrant evidencing the rights of the
Holder thereof to purchase the balance of the shares purchasable hereunder. Upon
receipt by the Company of this Warrant, together with the Exercise Price, at its
office, or by the stock transfer agent of the Company at its office, in proper
form for exercise, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of the Company shall then be closed or that certificates
representing such shares of Common Stock shall not then be actually delivered to
the Holder. The Company shall pay any and all documentary stamp or similar issue
or transfer taxes payable in respect of the issue or delivery of shares of
Common Stock on exercise of this Warrant.

                  1.2 CASHLESS EXERCISE. This Warrant may be exchanged, in whole
or in part (a "Warrant Exchange"), at any time, or from time to time, during the
period commencing on the date hereof and ending on the Expiration Date, into the
number of shares of Common Stock determined in accordance with this Section 1.2,
by presentation and surrender of this Warrant to the Company at its principal
office, or at the office of its stock transfer agent, if any, accompanied by a
notice (a "Notice of Exchange") stating that this Warrant is being exchanged and
the number of shares of Common Stock to be exchanged. In connection with any
Warrant Exchange, this Warrant shall represent the right to subscribe for and
acquire the number of shares of Common Stock (rounded to the nearest whole
number) equal to (i) the number of shares specified by the Holder in its Notice
of Exchange (the "Total Number") less the number of shares equal to the quotient
obtained by dividing (A) the product of the Total Number and the then




                                      -2-
<PAGE>   3

applicable Exercise Price by (B) the then fair market value (determined in
accordance with Section 3 below) per share of Common Stock. If this Warrant
should be exchanged in part only, the Company shall, upon surrender of this
Warrant for cancellation, execute and deliver a new Warrant evidencing the
rights of the Holder thereof to purchase the balance of the shares purchasable
hereunder. Upon receipt by the Company of this Warrant, together with a duly
executed Notice of Exchange, at its office, or by the stock transfer agent of
the Company at its office, the Holder shall be deemed to be the holder of record
of the shares of Common Stock issuable upon such exchange, notwithstanding that
the stock transfer books of the Company shall then be closed or that
certificates representing such shares of Common Stock shall not then be actually
delivered to the Holder. The Company shall pay any and all documentary stamp or
similar issue or transfer taxes payable in respect of the issue or delivery of
shares of Common Stock on exchange of this Warrant.

         2. RESERVATION OF SHARES. The Company will at all times reserve for
issuance and delivery upon exercise of this Warrant all shares of Common Stock
or other shares of capital stock of the Company (and Other Securities) from time
to time receivable upon exercise of this Warrant. All such shares (and Other
Securities) shall be duly authorized and, when issued upon such exercise, shall
be validly issued, fully paid and non-assessable and free of all preemptive
rights.

         3. FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant, but the
Company shall pay the Holder an amount equal to the fair market value of such
fractional share of Common Stock in lieu of each fraction of a share otherwise
called for upon any exercise of this Warrant. For purposes of this Warrant, the
fair market value of a share of Common Stock shall be determined as follows:

                  (a) If the Common Stock is listed on a National Securities
Exchange or admitted to unlisted trading privileges on such exchange or listed
for trading on the NASDAQ system, the current market value shall be the last
reported sale price of the Common Stock on such exchange or system on the last
business day prior to the date of exercise of this Warrant or if no such sale is
made on such day, the average of the closing bid and asked prices for such day
on such exchange or system; or

                  (b) If the Common Stock is not so listed or admitted to
unlisted trading privileges, the current market value shall be the mean of the
last reported bid and asked prices reported by the National Quotation Bureau,
Inc. on the last business day prior to the date of the exercise of this Warrant;
or

                  (c) If the Common Stock is not so listed or admitted to
unlisted trading privileges and bid and asked prices are not so reported, the
current market value shall be an amount, not less than book value thereof as at
the end of the most recent fiscal year of the Company ending prior to the date
of the exercise of the Warrant, determined by the Board of Directors of the
Company in good faith.

         4. EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT. This Warrant is
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender hereof to the Company or at the office of its stock transfer
agent, if any, for other Warrants of different denominations, entitling the
Holder or Holders thereof to purchase in the aggregate the same number of shares
of Common Stock purchasable hereunder. Upon surrender of this Warrant to the
Company or at the office of its stock transfer agent, if any, with the
Assignment Form annexed hereto duly executed and funds sufficient to pay any
transfer tax, subject to the provisions of Section 7 hereof, the Company shall,
without charge, execute and deliver a new Warrant in the name of the assignee
named in such instrument of assignment and this Warrant shall promptly be
canceled. This Warrant may be divided or combined with other Warrants that carry
the same rights upon presentation hereof at the office of the Company or at the
office of its stock transfer agent, if any, together with a written notice
specifying the names and denominations in which new Warrants are to be issued
and signed by the Holder hereof.

         5. RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed in this
Warrant.

         6. ANTI-DILUTION PROVISIONS.

                  6.1 ADJUSTMENT FOR RECAPITALIZATION. If the Company shall at
any time subdivide its outstanding shares of Common Stock (or Other Securities
at the time receivable upon the exercise of the Warrant) by recapitalization,
reclassification or split-up thereof, or if the Company shall declare a stock
dividend or distribute shares of Common Stock to its shareholders, the number of
shares of Common Stock subject to this Warrant immediately prior to such
subdivision shall be proportionately increased and the Exercise Price shall be
proportionately decreased, and if the Company shall at any time combine the
outstanding shares of Common Stock by recapitalization, reclassification or
combination thereof, the number of shares of Common Stock or Other Securities
subject to this Warrant immediately prior to such combination shall be
proportionately decreased and the Exercise Price shall be proportionately
increased. Any such adjustments pursuant to this Section 6.1 shall be effective
at the close of business on the effective date of such subdivision or
combination or if any adjustment is the result of a stock dividend or
distribution then the effective date for such adjustment based thereon shall be
the record date therefor.

                  6.2 ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.
In case of any reorganization of the Company (or any other entity, the
securities of which are at the time receivable on the exercise of this Warrant)
after the Base Date or in case after such date the Company (or any such other
entity) shall consolidate with or merge into another entity or convey all or
substantially all of its assets to another entity, then, and in each such case,
the Holder of this Warrant upon the exercise thereof as provided in Section 1 at
any time after the consummation of such reorganization, consolidation, merger or
conveyance, shall be entitled to receive, in lieu of the securities and property
receivable upon the exercise of this Warrant prior to such consummation, the
securities or property to which such Holder would have been entitled



                                      -4-
<PAGE>   5

upon such consummation if such Holder had exercised this Warrant immediately
prior thereto; in each such case, the terms of this Warrant shall be applicable
to the securities or property receivable upon the exercise of this Warrant after
such consummation.

                  6.3 NO DILUTION.

                  (a) From the date of issuance of this Warrant until the later
of (1) the first anniversary of the date of such issuance and (2) the date on
which the Company first consummates a sale of shares of its equity securities
(within the meaning of Section 3(a)(11) of the Securities Exchange Act of 1934,
as amended) or debt securities convertible into equity securities for gross cash
proceeds to the Company of more than $2.0 million (such period through such
later date, the "Reset Period") other than Excluded Shares (as hereinafter
defined), if the Company shall issue or enter into any agreement to issue any
shares of Common Stock other than Excluded Shares for consideration per share
(the "Issuance Price") less than the Exercise Price per share in effect
immediately prior to such issuance, the Exercise Price in effect immediately
prior to such issuance shall be reduced (but shall not be increased) to the
Issuance Price. For purposes hereof, the term "Excluded Shares" shall mean (1)
any shares of Common Stock issued in a transaction described in Sections 6.1 and
6.2 of this Warrant; (2) issuances of shares of Common Stock from time to time
pursuant to employment agreements, stock option or bonus plans authorized by the
Board of Directors of the Corporation as of the date hereof, (3) issuances of
Common Stock, or options to acquire shares of Common Stock, or securities
convertible into or exchangeable for Common Stock pursuant to the terms of any
acquisition by the Company of all or substantially all of the operating assets,
or more than fifty percent (50%) of the voting capital stock or other
controlling interest of any business entity in a transaction negotiated on an
arms-length basis and expressly approved in advance by the Board of Directors of
the Company; (4) issuances of shares of Common Stock from time to time upon the
exercise, exchange or conversion of warrants, options, convertible securities,
the Company's outstanding 8 1/4% Subordinated Convertible Notes Due 2003 or
other securities outstanding as of the date hereof and pursuant to the written
terms of such securities as they exist as of the date hereof, and (5) issuances
of shares of Common Stock from time to time pursuant to the anti-dilution
provisions of other securities of the Company, including shares of the Company's
outstanding Series B, Series C and Series D Convertible Preferred Stock. For
purposes hereof, "voting capital stock" shall be deemed to be capital stock of
any class or classes, however designated having ordinary voting power for the
election of members of the board of directors or other governing body and
"controlling" shall mean the possession, directly or indirectly, of the power to
direct or cause the direction of the management and policies of a party, whether
through the ownership of voting capital stock, by contract or otherwise.

                  (b) If, at any time subsequent to the Reset Period and prior
to the first anniversary of the expiration of the Reset Period, the Company
consummates a sale of shares of its Common Stock other than Excluded Shares for
consideration per share of Common Stock less than the Exercise Price per share
in effect immediately prior to such issuance, the Conversion Price in effect
immediately prior to such issuance shall be reduced (but shall not be increased)
to the price (calculated to the nearest cent) determined: by dividing (1) an
amount equal to the sum



                                      -5-
<PAGE>   6

of (A) the number of shares of Common Stock outstanding on a fully diluted basis
immediately prior to such issuance multiplied by the Exercise Price per share in
effect immediately prior to such issuance and (B) the consideration, if any,
received by the Corporation upon such issuance by (2) the number of shares of
Common Stock outstanding on a fully diluted basis immediately after such
issuance.

                  (c) If, at any time from the date of issuance of this Warrant
prior to the first anniversary of the expiration of the Reset Period, the
Company shall issue or enter into any agreement to issue any shares of Common
Stock other than Excluded Shares for consideration per share greater than the
Exercise Price but lower than the market price per share in effect immediately
prior to such issuance, the Exercise Price in effect immediately prior to such
issuance shall be reduced (but shall not be increased) to the price (calculated
to the nearest cent) determined by multiplying the Exercise Price in effect
immediately prior to such issuance by the factor determined by dividing (1) an
amount equal to the sum of (A) the number of shares of Common Stock outstanding
on a fully diluted basis immediately prior to such issuance multiplied by the
market price per share in effect immediately prior to such issuance and (B) the
consideration, if any, received by the Company upon such issuance by (2) the
number of shares of Common Stock outstanding on a fully diluted basis
immediately after such issuance multiplied by the market price per share in
effect immediately prior to such issuance; PROVIDED, however, no adjustment
shall be made to the Exercise Price if (1) such issuance is in connection with a
firm commitment underwritten public offering or (2) the consideration per share
is equal to or greater than 85% of the market price per share in effect
immediately prior to such issuance. For purposes hereof, the "market price" as
of any measurement date shall be the average of the closing prices of the Common
Stock for each of the 10 consecutive trading days immediately preceding such
measurement date.

                  (d) The Company will not, by amendment of its Articles of
Incorporation or through reorganization, consolidation, merger, dissolution,
issue or sale of securities, sale of assets or any other voluntary action, avoid
or seek to avoid the observance or performance of any of the terms of this
Warrant, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the Holder of this Warrant against
dilution or other impairment.

                  (e) For further clarity, any change to the conversion price or
other terms of the 8 1/4% Subordinated Convertible Notes Due 2003 shall not
count toward determining the Reset Period, but shall be taken into account in
determining whether any adjustment to the Exercise Price is due under this
Section 6.3.

                  (f) The Exercise Price shall be subject to adjustment from
time to time as previously provided in this section 6.3. Upon each adjustment of
the Exercise Price, the holder of the Warrant evidenced hereby shall thereafter
be entitled to purchase, at the Exercise Price resulting from such adjustment,
the number of shares of Common Stock (calculated to the nearest whole share
pursuant to Section 3) obtained by multiplying the Exercise Price in effect





                                      -6-
<PAGE>   7

immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment and dividing the product by
the Exercise Price resulting from such adjustment.

                  6.4 CERTIFICATE AS TO ADJUSTMENTS. In each case of an
adjustment in the number of shares of Warrant Stock or Other Securities
receivable on the exercise of this Warrant, or the Exercise Price, the Company
at its expense will promptly compute such adjustment in accordance with the
terms of this Warrant and prepare a certificate executed by an executive officer
of the Company setting forth such adjustment and showing in detail the facts
upon which such adjustment is based. The Company will forthwith mail a copy of
each such certificate to the Holder.

                  6.5 NOTICES OF RECORD DATE, ETC. In case:

                  (a) the Company shall take a record of the holders of its
Common Stock (or Other Securities at the time receivable upon the exercise of
the Warrant) for the purpose of entitling them to receive any dividend (other
than a cash dividend at the same rate as the rate of the last cash dividend
theretofore paid) or other distribution, or any right to subscribe for, purchase
or otherwise acquire any shares of stock of any class or any other securities,
or to receive any other right; or

                  (b) of any capital reorganization of the Company, any
reclassification of the capital stock of the Company, any consolidation or
merger of the Company with or into another entity, or any conveyance of all or
substantially all of the assets of the Company to another entity; or

                  (c) of any voluntary or involuntary dissolution, liquidation,
partial liquidation or winding up of the Company, or

                  (d) any event resulting in the expiration of the Reset Period,

then, and in each such case, the Company shall mail or cause to be mailed to
each Holder of the Warrant at the time outstanding a notice specifying, as the
case may be, (i) the date on which a record is to be taken for the purpose of
such dividend, distribution or right, and stating the amount and character of
such dividend, distribution or right, or (ii) the date on which such
reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding up is to take place, and the time, if any,
to be fixed, as to which the holders of record of Common Stock (or such other
securities at the time receivable upon the exercise of the Warrant) shall be
entitled to exchange their shares of Common Stock (or such other securities) for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or
winding up. Such notice shall be mailed at least 20 days prior to the date
therein specified.

         Section 2.1. OFFICERS AND DIRECTORS OF THE CORPORATION.

         (a) The Corporation and the Shareholders agree that the Board of
Directors of the Corporation shall consist of five (5) natural persons. It is
agreed that immediately following the execution of this Agreement and thereafter
during the Term (as hereinafter defined) of this Agreement, the Shareholders
shall vote, and shall cause their respective Affiliates to vote, their shares of
Stock, and those shares beneficially owned by them, respectively (within the
meaning of Rule 13d-3 under the Securities Exchange Act of 1934), and the
Corporation shall take all such other action, to elect or appoint two (2)
directors nominated by written instruction delivered by Series D Preferred
Shareholders holding two-thirds or more of the outstanding shares of Series D
Preferred Stock of the Corporation (the "REQUIRED PREFERRED SHAREHOLDERS") as
members of the Corporation's Board of Directors (the "PREFERRED SHAREHOLDER
DIRECTORS"), and to elect or appoint as successors thereto, respectively, solely
those replacements nominated as aforesaid.

         (b) Without limiting any other provision contained in paragraph (a)
immediately preceding, in the event that the Preferred Shareholder Directors
have not been elected or appointed prior to June 30, 2000, the Required
Preferred Shareholders shall have the right, exercisable by written notice to

Directors to consist of nine natural persons, four of whom shall be nominated by

The Shareholders and the Corporation agree that immediately following the
execution of this Agreement and thereafter during the Term, such committees
shall be created and shall include (i) an executive committee, (ii) an audit and
finance committee and (iii) a compensation committee. The duties and functions
of such committees shall be set forth in the Bylaws or in the action of the
Board of Directors creating such committees; provided that the mandate of each

Directors. Each of the Preferred Shareholder Directors shall have the right to

change in control of the Corporation. If the Required Preferred Shareholders
notify Mansur of their intention to effect a change in control, the Corporation
and its Board of Directors and the Shareholders will obtain the immediate
resignation of a standing independent director from the Board of Directors,
failing which the Board of Directors shall forthwith be expanded by two. The
vacancy or vacancies in the Board of Directors resulting from the resignation of
such standing independent director (other than the Preferred Shareholder
Directors) or such expansion shall be filled by a nominee of the Required
Preferred Shareholders. During the Term of this Agreement, the Shareholders
agree to vote, and shall cause their respective Affiliates to vote, their shares
of Stock, and those shares beneficially owned by them, respectively, to elect
and reelect the director nominees of the Required Preferred Shareholders and any
replacements therefor.

Articles or Bylaws as in effect on the date hereof, all actions of the Board of
Directors or shareholders of the Corporation shall be taken upon or pursuant to
a majority vote of the Board of Directors or of the votes held by beneficial
owners of shares of Stock entitled to vote, respectively, who are present in
person or by proxy at the corresponding meeting (provided a quorum exists).

         (b) During the Term, the Corporation, the Board of Directors (including
any committee or subcommittee thereof) and the Shareholders shall not take any
of the actions, enter into any commitment to take any of the actions, or
otherwise agree to take any of the actions, specified below unless such action
has been first approved by all of the Preferred Shareholder Directors:

         date hereof, of any Indebtedness by the Corporation in an amount
         exceeding $250,000 in the aggregate (other than Indebtedness which
         constitutes financing for commitments of the Corporation or any
         Subsidiary thereof existing as of the date hereof, the refinancing or
         successive refinancing of Indebtedness of the Corporation or any
         Subsidiary (other than the Notes) existing as of the date hereof, and

of its provisions. If the Parties to this Agreement are forced to institute
legal proceedings to enforce their rights in accordance with the provisions of
this Agreement, they shall be entitled to recover their reasonable attorneys'
fees and court costs incurred in enforcing such rights.

                      - OPERATIONS CONSOLIDATED NATIONWIDE
                      - $2MM RAISED THROUGH PRIVATE PLACEMENT


MIAMI, Florida, May 11, 2000-- Mansur Industries Inc. (NASDAQ: MANS) today
reported its first quarter 2000 operating results.

Revenues for the three months ended March 31, 2000 were $4,286,000 compared to
revenues of $4,013,000 in the corresponding period of 1999, a 7% increase. The
Company incurred an operating loss for the three months ended March 31, 2000 of
$3,463,000 compared with an operating loss of $3,550,000 in the corresponding
period of 1999. The Company's net loss for the three months ended March 31, 2000
was $4,243,000 or a loss of 89 cents per share, compared with a net loss of
$3,997,000 or a loss of 87 cents per share, in the corresponding period of 1999.

First quarter revenues were negatively impacted as a result of short term
disruptions caused by the aggressive consolidation of the Company's distribution
and service infrastructure nationwide eliminating redundant or nonproductive
resources in the field and in the corporate offices, while restructuring the
direct sales and service organization into 15 tightly controlled districts. Paul
I. Mansur, Chief Executive Officer, stated that "we are pleased to report that
the Company has undergone an ambitious streamlining of its entire organization
including a reorganization of our direct sales force to enhance efficiency and
productivity while". Mr. Mansur further stated that "although the Company's
aggressive consolidation has negatively impacted first quarter sales and is
expected to impact second quarter sales to a lesser extent, we believe that the
changes will facilitate the Company's transition to profitability during the
second half of 2000 and significantly enhance long term profitability."

Mansur Industries also announced today the private sale of $2 million of 8.25%
Convertible Preferred Stock redeemable in 2004. The Preferred Stock is
convertible into common stock at a price equal to $5.50 per share. The Preferred
Stock was purchased by current preferred shareholders of the Company, Hanseatic
Americas LDC and Environmental Opportunities Funds II L.P., in equal amounts of
$1 million each. The investors also received warrants to acquire an aggregate of
363,636 shares of common stock at an exercise price of $5.50 per share.
Representatives of the investors will be added to the Company's Board of
Directors. The Company plans to use the proceeds for general working capital
purposes.
