                                    EXHIBIT A
 
                                 CERTIFICATE OF
                       DESIGNATION, PREFERENCES AND RIGHTS
                               OF THE TERMS OF THE
                            SERIES A PREFERRED STOCK
 
     Section 1. Designation and Amount. The Series A Convertible Preferred
Stock, $0.001 par value per share (the "Series A Preferred Stock") shall consist
of 5,000,000 shares and will have the designations, preferences, voting powers
and privileges set forth below. The number of shares of Series A Preferred Stock
may be increased or decreased by a resolution duly adopted by the Board of
Directors of the Corporation and by the filing of an amendment to the
Corporation's Articles of Incorporation pursuant to the provisions of the Nevada
Business Corporation Act stating that such increase or decrease has been so
authorized.
 
     Section 2. Dividends.
 
          (A) Preferred Stock Dividend Preference. The holders of Series A
     Preferred Stock, in preference to the holders of Common Stock, $.001 par
     value per share (the "Common Stock"), shall be entitled to receive, but
     only out of any funds legally available for the declaration of dividends,
     cumulative, preferential dividends payable as provided in paragraph (B)
     below of this Section 2. Dividends on shares of Series A Preferred Stock
     shall accrue and be cumulative from the date of issuance of such shares of
     Series A Preferred Stock, and shall accumulate and accrue from day to day
     thereafter. No dividends or distributions (other than dividends or
     distributions on Common Stock payable in Common Stock) shall be paid upon,
     or declared or set apart for, the Common Stock, nor shall any Common Stock
     be purchased, redeemed, retired, or otherwise acquired by the Corporation,
     unless and until all cumulative dividends then owed on the then outstanding
     shares of Series A Preferred Stock have been paid in full.
 
          (B) Payment of Series A Preferred Stock Dividends. Dividends on
     outstanding shares of Series A Preferred Stock shall be payable annually,
     in arrears, on the last day of May of each year, beginning on the last day
     of May 2002 at a rate of 8% of the Liquidation Amount in cash, or, at the
     option of the Corporation, in shares of Series A Preferred Stock at the
     rate of 0.08 shares for each outstanding share of Series A Preferred Stock;
     provided, however, that if the Corporation pays in shares of Series A
     Preferred Stock, the Corporation may issue cash in lieu of fractional
     shares.
 
          (C) Common Stock. Subject to paragraphs (A) and (B) above of this
     Section 2, (i) dividends may be declared and paid on Common Stock, and (ii)
     Common Stock may be purchased, retired, or otherwise acquired, in either
     case when and as determined by the Board of Directors, out of any funds
     legally available for such purposes.
 
     Section 3. Preference on Liquidation.
 
          (A) In the event of any voluntary or involuntary liquidation,
     dissolution or winding up of the Corporation (a "Liquidation") the holders
     of shares of the Series A Preferred
 
 
 
                                       A-1
 
<PAGE>
 
     Stock then outstanding shall be entitled to be paid, out of the assets of
     the Corporation available for distribution to its shareholders, whether
     from capital, surplus or earnings, before any payment shall be made in
     respect of the Common Stock, an amount equal to $1.00 per share of Series A
     Preferred Stock (the "Liquidation Amount"), plus all accrued and unpaid
     dividends as set forth above in Section 2 with respect to such series to
     the date fixed for distribution. If, upon a Liquidation, the Corporation
     pays less than the total Liquidation Amount to holders of shares of Series
     A Preferred Stock, such payments shall be distributed pro rata on a
     share-by-share basis among all shares of Series A Preferred Stock at the
     time outstanding. Upon Liquidation, the Corporation shall not make any
     dividends or distributions to holders of Common Stock until it has paid the
     total Liquidation Amount plus all accrued but unpaid dividends to each
     holder of shares of Series A Preferred Stock.
 
          (B) After setting apart or paying in full the preferential amounts due
     the holders of Series A Preferred Stock, such holders will not be entitled
     to any further participation in any distribution of assets of the
     Corporation.
 
     Section 4. Voting. Except as provided in this Designation or otherwise
required by law, no holder of shares of Series A Preferred Stock shall be
entitled to vote on any matter presented to shareholders for a vote. If a vote
of the holders of Series A Preferred Stock is required by law, each holder of
Series A Preferred Stock shall be entitled to the number of votes equal to the
number of shares of Common Stock into which such shares of Series A Preferred
Stock could be converted on the record date for the vote or consent of
shareholders and shall have voting rights and powers equal to the voting rights
and powers of the Common Stock. The holder of each share of Series A Preferred
Stock shall be entitled to notice of any shareholders' meeting in accordance
with the Bylaws of the Corporation. Fractional votes by the holders of Series A
Preferred Stock shall not, however, be permitted and any fractional voting
rights resulting from the above formula (after aggregating all shares into which
shares of Series A Preferred Stock held by each holder could be converted) shall
be rounded to the nearest whole number.
 
     Section 5. Conversion. The holders of the Series A Preferred Stock shall
have conversion rights as follows (the "Conversion Rights"):
 
          (A) Each share of Series A Preferred Stock shall be convertible, at
     the option of the holder thereof, at any time after the date of issuance of
     such share at the office of the Corporation or any transfer agent for the
     Series A Preferred Stock, into Common Stock as more fully described below.
     The number of fully paid and nonassessable shares of Common Stock into
     which each share of Series A Preferred Stock may be converted shall be
     determined by dividing $1.00 by the Conversion Price (as hereinafter
     defined) in effect at the time of conversion. The "Conversion Price" shall
     initially be $2.38, subject to adjustment as provided in Section 5(F)
     below.
 
          (B) Each share of Series A Preferred Stock shall automatically be
     converted into shares of Common Stock utilizing the then effective
     Conversion Price immediately upon obtaining the written consent of the
     holders of at least two-thirds of the outstanding Series A Preferred Stock
     to such conversion.
 
          (C) Each share of Series A Preferred Stock shall be convertible, at
     the option of the Corporation, at any time after the Common Stock has been
     publicly traded on a national securities exchange or on Nasdaq for at least
     20 consecutive trading days at a closing price of at
 
 
 
                                       A-2
 
<PAGE>
 
     least $3.00 (as adjusted to reflect any stock split, stock dividend,
     combination, recapitalization or similar event) or higher; provided, that
     if the market price of the Common Stock thereafter declines to a closing
     price that is below $3.00 per share, the Corporation may not cause the
     Series A Preferred Stock to convert into Common Stock until it has again
     been publicly traded for at least 20 consecutive trading days at a closing
     price of at least $3.00 (as adjusted to reflect any stock split, stock
     dividend, combination, recapitalization or similar event).
 
          (D) No fractional shares of Common Stock shall be issued upon
     conversion of the Series A Preferred Stock, and any shares of Series A
     Preferred Stock surrendered for conversion which would otherwise result in
     a fractional share of Common Stock shall be redeemed for the then fair
     market value thereof as determined by the Corporation's Board of Directors,
     payable as promptly as possible whenever funds are legally available
     therefor. If more than one share of Series A Preferred Stock is surrendered
     for conversion at any one time by the same holder, the number of full
     shares of Common Stock to be issued upon conversion shall be computed on
     the basis of the aggregate number of shares of Series A Preferred Stock so
     surrendered.
 
          (E) Before any holder of Series A Preferred Stock shall be entitled to
     convert the same into shares of Common Stock, it shall surrender the
     certificate or certificates therefor at the office of the Corporation or of
     any transfer agent for the Series A Preferred Stock, and shall give written
     notice to the Corporation at such office that it elects to convert the same
     and shall state therein the name or names in which it wishes the
     certificate or certificates for shares of Common Stock to be issued. The
     Corporation shall, as soon as practicable thereafter, issue and deliver at
     such office to such holder of Series A Preferred Stock, or to its nominee
     or nominees, a certificate or certificates for the number of shares of
     Common Stock to which it shall be entitled as aforesaid. Such conversion
     shall be deemed to have been made immediately prior to the close of
     business on the date of such surrender of the shares of Series A Preferred
     Stock to be converted, and the person or persons entitled to receive the
     shares of Common Stock issuable upon such conversion shall be treated for
     all purposes as the record holder or holders of such shares of Common Stock
     on such date.
 
          (F) Adjustment of Number of Shares and Conversion Price. The
     Conversion Price and the number of shares of Common Stock issuable upon
     conversion of the Series A Preferred Stock shall be subject to adjustment
     from time to time as provided in this Section 5(F).
 
               (i) Issuance of Additional Shares of Common Stock. If the
          Corporation issues or sells any shares ("Additional Shares") of Common
          Stock for a consideration per share less than the Conversion Price,
          the Conversion Price shall be adjusted to the price calculated by
          multiplying the Conversion Price in effect immediately before the
          issuance of the Additional Shares by a fraction:
 
                    A. the numerator of which shall be the number of shares of
               Common Stock outstanding immediately prior to the issuance of
               such Additional Shares plus the number of shares of Common Stock
               which the aggregate consideration for the total number of such
               Additional Shares so issued would purchase at the Conversion
               Price, and
 
 
 
                                       A-3
 
<PAGE>
 
                    B. the denominator of which shall be the number of shares of
               Common Stock outstanding immediately prior to the issuance of
               such Additional Shares plus the number of such Additional Shares
               so issued.
 
          For purposes of this Section 5(F)(i), the date as of which the
          Conversion Price shall be computed shall be the earlier of the date
          upon which the Corporation shall (i) enter into a firm contract for
          the issuance of such shares or (ii) issue such shares.
 
               (ii) Adjustment of Number of Shares. Upon any adjustment of the
          Conversion Price as provided in this Section 5(F), the holder of
          shares of Series A Preferred Stock shall thereafter be entitled to
          purchase, at the Conversion Price resulting from the adjustment, the
          number of shares of Common Stock (calculated to the nearest 1/100th of
          a share) obtained by multiplying the Conversion Price in effect
          immediately before the adjustment by the number of shares of Common
          Stock purchasable hereunder immediately before the adjustment and
          dividing the product thereof by the Conversion Price resulting from
          the adjustment.
 
          (G) Provisions Applicable to Section 5(F). For purposes of Section
     5(F), the following Sections 5(G)(i) through (xii), inclusive, shall be
     applicable:
 
               (i) Issuance of Options or Other Rights. If the Corporation in
          any manner grants (whether directly or by assumption in a merger or
          otherwise) any rights to subscribe for or to purchase, or any options
          for the purchase of, (x) Common Stock or (y) evidences of
          indebtedness, shares of stock or other securities that are convertible
          into or exchangeable for, with or without payment of additional
          consideration in cash or property, additional shares of Common Stock,
          either immediately or upon a specified date or the happening of a
          specified event ("Convertible Securities"), whether or not such rights
          or options or the right to convert or exchange any such Convertible
          Securities are immediately exercisable, and if the price per share for
          which shares of Common Stock are issuable upon the conversion of such
          rights or options or upon conversion or exchange of such Convertible
          Securities is less than the Conversion Price per share of Common Stock
          existing immediately before the granting of such rights or options,
          then the maximum number of shares of Common Stock issuable upon the
          conversion of such rights or options or upon conversion or exchange of
          the maximum amount of such Convertible Securities issuable upon the
          conversion of such rights or options shall (as of the date for the
          determination of the Conversion Price per share of Common Stock as
          hereinafter provided) be deemed to be outstanding and to have been
          issued for such price per share. The price per share for which shares
          of Common Stock are issuable upon the conversion of such right or
          options or upon conversion or exchange of such Convertible Securities
          shall be determined by dividing (1) the total amount, if any, received
          or receivable by the Corporation as consideration for the granting of
          such rights or options, plus the minimum aggregate amount of
          additional consideration payable to the Corporation upon the
          conversion of such rights or options, plus, in the case of such
          Convertible Securities, the minimum aggregate amount of additional
          consideration, if any, payable upon the conversion or exchange
          thereof, by (2) the total maximum number of shares of Common Stock
          issuable upon the conversion of such rights or options or upon the
          conversion or exchange of all such Convertible Securities issuable
          upon the conversion of such rights or options. No further adjustments
          of the Conversion Price shall be made upon the actual issue of such
          Common Stock or of such rights or options or
 
 
 
                                       A-4
 
<PAGE>
 
          upon the actual issue of such Common Stock upon conversion or exchange
          of such Convertible Securities except as otherwise provided in Section
          5(G)(iii) below. For purposes of this Section 5(G)(i), the date as of
          which the Conversion Price per share of Common Stock shall be computed
          shall be the earlier of the date upon which the Corporation shall (i)
          enter into a firm contract for the issuance of such rights or other
          options or (ii) issue such rights or other options.
 
               (ii) Issuance of Convertible Securities. If the Corporation in
          any manner issues or sells (whether directly or by assumption in a
          merger or otherwise) any Convertible Securities, whether or not the
          rights to exchange or convert thereunder are immediately exercisable,
          and the price per share for which shares of Common Stock are issuable
          upon such conversion or exchange shall be less than the Conversion
          Price per share of Common Stock existing immediately prior to the time
          of such issue or sale, then the maximum number of shares of Common
          Stock issuable upon conversion or exchange of all such Convertible
          Securities shall (as of the date for the determination of the
          Conversion Price per share of Common Stock as hereinafter provided) be
          deemed to be outstanding and to have been issued for such price per
          share; provided however, except as otherwise specified in Section
          5(G)(iii) below, (1) no further adjustments of the Conversion Price
          shall be made upon the actual issuance of such Common Stock upon
          conversion or exchange of such Convertible Securities and (2) if any
          such issuance or sale of such Convertible Securities is made upon
          conversion of any rights to subscribe for or to purchase or any option
          to purchase any such Convertible Securities for which adjustments of
          the Conversion Price have been or are to be made under other
          provisions of Sections 5(F) and 5(G), no further adjustment of the
          Conversion Price shall be made by reason of such issuance or sale. The
          price per share for which shares of Common Stock are issuable upon
          such conversion or exchange shall be determined by dividing (x) the
          total amount received or receivable by the Corporation as
          consideration for the issue or sale of such Convertible Securities,
          plus the minimum aggregate amount of additional consideration, if any,
          payable to the Corporation upon the conversion or exchange thereof, by
          (y) the total maximum number of shares of Common Stock issuable upon
          the conversion or exchange of all such Convertible Securities. For
          purposes of this Section 5(G)(ii), the date as of which the Conversion
          Price per share of Common Stock shall be computed shall be the earlier
          of the date upon which (i) the Corporation shall enter into a firm
          contract for the issuance of such Convertible Securities or (ii) such
          Convertible Securities are actually issued.
 
               (iii) Readjustment of Conversion Price. If (i) the purchase price
          provided for in any rights or options referred to in Section 5(G)(i)
          above, (ii) the additional consideration, if any, payable upon the
          conversion or exchange of Convertible Securities referred to in
          Section 5(G)(i) or 5(G)(ii) above, or (iii) the rate at which any
          Convertible Securities referred to in Section 5(G)(i) or 5(G)(ii)
          above are convertible into or exchangeable for Common Stock shall
          change (other than under or by reason of provisions designed to
          protect against dilution), the Conversion Price in effect at the time
          of such event shall forthwith be readjusted to the Conversion Price
          that would have been in effect at such time had such rights, options
          or Convertible Securities still outstanding provided for such changed
          purchase price, additional consideration or conversion rate, as the
          case may be, at the time initially granted, issued or sold. On the
          expiration of any such option or right or the termination of any such
          right to convert or exchange such
 
 
                                       A-5
 
<PAGE>
 
          Convertible Securities, the Conversion Price then in effect shall be
          increased to the Conversion Price that would have been in effect at
          the time of such expiration or termination had such right, option or
          Convertible Security never been issued, and the Common Stock issuable
          thereunder shall no longer be deemed to be outstanding. If the
          purchase price provided for in any such rights or options referred to
          in Section 5(G)(i) above or the rate at which any Convertible
          Securities referred to in Section 5(G)(i) or 5(G)(ii) are convertible
          into or exchangeable for Common Stock, shall be reduced at any time
          under or by reason of provisions with respect thereto designed to
          protect against dilution, then in case of the delivery of Common Stock
          upon the conversion in any such rights or options or upon conversion
          or exchange of any such Convertible Securities, the Conversion Price
          then in effect hereunder shall forthwith be adjusted to such amount as
          would have obtained had such right, option or Convertible Securities
          never been issued as to such Common Stock and had adjustments never
          been made upon the issuance of the shares of Common Stock delivered as
          aforesaid, but only if as a result of such adjustment the Conversion
          Price then in effect hereunder is thereby reduced. In the event any
          such adjustment would reduce the Conversion Price to an amount less
          than the then par value of the Common Stock, the Corporation shall
          cause its Articles of Incorporation to be amended to reduce the par
          value of the Common Stock to an amount equal to or less than the
          adjusted Conversion Price.
 
               (iv) Minimum Adjustment. If any adjustment of the Conversion
          Price pursuant to Section 5(F) results in an adjustment of less than
          $.001 per share of Common Stock, no such adjustment shall be made, but
          any such lesser adjustment shall be carried forward and shall be made
          at the time and together with the next subsequent adjustment that,
          together with any adjustments so carried forward, shall amount to
          $.001 or more per share of Common Stock; provided, however, upon any
          adjustment of the Conversion Price resulting from (i) the declaration
          of a dividend upon, or the mailing of any distribution in respect of,
          any stock of the Corporation payable in Common Stock or Convertible
          Securities or (ii) the reclassification, by subdivision, combination
          or otherwise, of the Common Stock into a greater or smaller number of
          shares, the foregoing figure of $.001 per share (or such figure as
          last adjusted) shall be proportionately adjusted; provided, further,
          upon the conversion of the Series A Preferred Stock, the Corporation
          shall make all necessary adjustments not theretofore made to the
          Conversion Price up to and including the date upon which the Series A
          Preferred Stock is converted.
 
               (v) Consideration for Dividends in Securities. If the Corporation
          declares a dividend or makes any other distribution upon any stock of
          the Corporation payable in either case in Common Stock or Convertible
          Securities, such Common Stock or Convertible Securities, as the case
          may be, issuable in payment of such dividend or distribution shall be
          deemed to have been issued or sold without consideration.
 
               (vi) Consideration for Rights or Options. If any rights or
          options to purchase any shares of Common Stock or Convertible
          Securities are issued in connection with the issue or sale of other
          securities of the Corporation, together comprising one integral
          transaction in which no specific consideration is allocated to the
          rights or options, the rights or options shall be deemed to have been
          issued without consideration.
 
               (vii) Determination of Consideration upon Payment of Cash,
          Property or Merger. If any shares of Common Stock or Convertible
          Securities or any rights or
 
 
                                       A-6
 
<PAGE>
 
          options to purchase any Common Stock or Convertible Securities are
          issued or sold for cash, the consideration received therefor shall be
          deemed to be the net amount received by the Corporation therefor,
          after deduction of any accrued interest, dividends or any expenses
          incurred or any underwriting commissions or concessions paid or
          allowed by the Corporation in connection therewith. If any shares of
          Common Stock or Convertible Securities or any rights or options to
          purchase any such Common Stock or Convertible Securities are issued
          for a consideration other than cash, the amount of the consideration
          other than cash received by the Corporation shall be deemed to be the
          fair market value on the date of issue of the securities so issued by
          the Corporation, as determined in good faith by the Board of Directors
          of the Corporation, less any expenses incurred by the Corporation in
          connection therewith. If any shares of Common Stock or Convertible
          Securities or any rights or options to purchase such Common Stock or
          Convertible Securities are issued in connection with any merger or
          consolidation in which the Corporation is the surviving corporation,
          the amount of consideration therefor shall be deemed to be the fair
          market value thereof on the date of issue, as determined in good faith
          by the Board of Directors of the Corporation, for such portion of the
          assets and business of the non-surviving corporation as the Board of
          Directors shall attribute to such Common Stock, Convertible
          Securities, rights or options, as the case may be. In the event of any
          consolidation or merger of the Corporation in which the Corporation is
          not the surviving corporation or in the event of any sale of all or
          substantially all of the assets of the Corporation for stock or other
          securities of any corporation, the Corporation shall be deemed to have
          issued a number of shares of its Common Stock for stock or securities
          of the other corporation computed on the basis of the actual exchange
          ratio on which the transaction was predicated and for a consideration
          equal to the fair market value on the date of such transaction of such
          stock or securities of the other corporation, and if any such
          calculation results in adjustment of the Conversion Price, the
          determination of the number of shares of Common Stock issuable upon
          conversion of the Series A Preferred Stock immediately prior to such
          merger, consolidation or sale, for the purposes of Section 5(G)(xi)
          below, shall be made after giving effect to such adjustment of the
          Conversion Price.
 
               (viii) Record Date. If the Corporation takes a record of the
          holders of the Common Stock for the purpose of entitling them (i) to
          receive a dividend or other distribution payable in Common Stock or in
          Convertible Securities or (ii) to subscribe for or purchase Common
          Stock or Convertible Securities, then the record date shall be deemed
          to be the date of the issue or sale of the shares of Common Stock
          deemed to have been issued or sold upon the declaration of the
          dividend or the making of such other distribution or the date of the
          granting of the right of subscription or purchase, as the case may be.
 
               (ix) Shares Outstanding. The number of shares of Common Stock
          deemed to be outstanding at any given time shall (i) include shares of
          Common Stock issuable in respect of scrip certificates that have been
          issued in lieu of fractional shares of Common Stock, but (ii) exclude
          (x) shares of Common Stock in the treasury of the Corporation or any
          subsidiary of the Corporation, (y) shares of Common Stock previously
          issued upon the conversion of the Series A Preferred Stock and (z)
          shares of Common Stock issuable upon the conversion of the Series A
          Preferred Stock.
 
 
 
                                       A-7
 
<PAGE>
 
               (x) Splits and Combinations. If the Corporation at any time
          subdivides its outstanding shares of Common Stock into a greater
          number of shares, the Conversion Price in effect immediately before
          the subdivision shall be proportionately reduced, and, conversely, if
          the outstanding shares of Common Stock are combined into a smaller
          number of shares, the Conversion Price in effect immediately before
          the combination shall be proportionately increased.
 
               (xi) Reorganization, Reclassification or Recapitalization of
          Corporation. In case of any capital reorganization or reclassification
          or recapitalization of the capital stock of the Corporation (other
          than in the cases referred to in Section 5(G)(x) or in case of the
          consolidation or merger of the Corporation with or into another
          corporation or other business entity or in case of the sale or
          transfer of the property of the Corporation as an entirety or
          substantially as an entirety, there shall thereafter be deliverable
          upon the conversion of the Series A Preferred Stock or any portion
          thereof (in lieu of or in addition to the number of shares of Common
          Stock theretofore deliverable) the number of shares of stock or other
          securities or property to which the holder of the number of shares of
          Common Stock that would otherwise have been deliverable upon the
          conversion of the Series A Preferred Stock or any portion thereof at
          the time would have been entitled upon such capital reorganization,
          reclassification or recapitalization of capital stock, consolidation,
          merger or sale, and at the same aggregate Conversion Price. Prior to
          and as a condition of the consummation of any transaction described in
          the preceding sentence, the Corporation shall make appropriate written
          adjustments in the application of the provisions herein set forth
          reasonably satisfactory to the holders of the Series A Preferred Stock
          entitled to not less than a majority of the shares of Common Stock
          issuable upon the conversion thereof with respect to the rights and
          interests of the holders of the Series A Preferred Stock so that the
          provisions set forth herein shall thereafter be applicable, as nearly
          as possible, in relation to any shares of stock or other securities or
          other property thereafter deliverable upon conversion of the Series A
          Preferred Stock. Any such adjustment shall be made by and set forth in
          a supplemental agreement between the Corporation and the successor
          entity and be approved by the holders of the Series A Preferred Stock
          entitled to not less than a majority of the shares of Common Stock
          issuable upon the conversion thereof.
 
               (xii) Exempt Issuances. Notwithstanding the prior provisions of
          this Section 5(G), no adjustment of the Conversion Price or the number
          of shares of Common Stock issuable upon conversion of the Series A
          Preferred Stock shall be made by reason of:
 
                    A. Common Stock issued upon conversion of the Series A
               Preferred Stock;
 
                    B. securities from time to time issuable or issued to
               employees, directors or consultants of the Corporation pursuant
               to stock option plans approved by a majority of the shareholders
               of the Corporation not to exceed 15% of the fully diluted shares
               of Common Stock then outstanding;
 
                    C. securities issued in connection with an acquisition of
               all or part of another business is approved by the Board of
               Directors of the Corporation;
 
 
                                       A-8
 
<PAGE>
 
                    D. securities issued to the holders of the Series A
               Preferred Stock as dividends; and
 
                    E. securities outstanding or securities issued upon exercise
               or conversion of securities outstanding as of the filing of this
               Designation with the Secretary of State of the State of Nevada
               including but not limited to the securities issued with respect
               to the merger of an indirect subsidiary of the Corporation with
               and into Petrocon Engineering, Inc.
 
          (H) The Corporation will not, by amendment of its Articles of
     Incorporation or Certificate of Designation, or through any reorganization,
     transfer of assets, consolidation, merger, dissolution, issue or sale of
     securities or any other voluntary action, avoid or seek to avoid the
     observance or performance of any of the terms to be observed or performed
     hereunder by the Corporation, but will at all times in good faith assist in
     the carrying out of all the provisions of this Section 5 and in the taking
     of all such action as may be necessary or appropriate in order to protect
     the conversion rights of the holders of the Series A Preferred Stock
     against impairment.
 
          (I) The Corporation shall at all times reserve and keep available, out
     of its authorized but unissued Common Stock, solely for the purpose of
     effecting the conversion of the Series A Preferred Stock, the full number
     of shares of Common Stock deliverable upon the conversion of all shares of
     Series A Preferred Stock from time to time outstanding. The Corporation
     shall from time to time (subject to obtaining necessary director and
     shareholder action), in accordance with the laws of the State of Nevada,
     increase the authorized amount of its Common Stock if at any time the
     authorized number of shares of its Common Stock remaining unissued shall
     not be sufficient to permit the conversion of all of the shares of Series A
     Preferred Stock at the time outstanding. The Corporation will take such
     corporate action as may be necessary to increase its authorized Common
     Stock, including, without limitation, using its reasonable best efforts to
     obtain the requisite shareholder approval to amend its Articles of
     Incorporation.
 
     Section 6. Status of Converted Stock. If any shares of Series A Preferred
Stock shall be converted pursuant to Section 5, the shares so converted shall be
cancelled and shall not be issuable by the Corporation, and the Articles of
Incorporation of the Corporation shall be appropriately amended to effect the
corresponding reduction in the Corporation's authorized capital.
 
     Section 7. Redemption.
 
          (A) Optional Redemption. At any time and from time to time after the
     issuance of the Series A Preferred Stock, the Corporation may, at its
     option, redeem all or part (but not less than 25% of the shares of Series A
     Preferred Stock then outstanding) of the outstanding shares of Series A
     Preferred Stock on a date specified by the Corporation (the "Optional
     Redemption Date") by paying to the holders thereof an amount equal to the
     Liquidation Amount plus the sum of all accrued but unpaid dividends on such
     shares (the "Redemption Price") in cash out of funds legally available for
     such purpose. Any redemption effected pursuant to this subsection 7(A)
     shall be made on a pro rata basis among the holders of the Series A
     Preferred Stock in proportion to the number of shares of Series A Preferred
     Stock then held by such holders.
 
 
                                       A-9
 
<PAGE>
 
          (B) Mandatory Redemption. To the extent legally permitted, at any time
     after July 31, 2008, the holders of not less than two-thirds of the then
     outstanding Series A Preferred Stock, voting together as a single class may
     demand, by delivery of a written notice to the Corporation (the "Mandatory
     Redemption Notice"), that the Corporation redeem all (but not less than
     all) of the shares of Series A Preferred Stock then outstanding on a date
     (the "Mandatory Redemption Date") that is not less than 30 nor more than 90
     days from the date of the Mandatory Redemption Notice by paying to the
     holders thereof an amount equal to the Redemption Price in cash out of
     funds legally available for such purpose.
 
          (C) As used herein and in Section 7(D) below, the term "Redemption
     Date" shall refer to both the Mandatory Redemption Date and the Optional
     Redemption Date. At least 15 but no more than 30 days prior to each
     Redemption Date, written notice shall be mailed, first class postage
     prepaid, to each holder of record of the Series A Preferred Stock to be
     redeemed notifying such holder of the redemption to be effected on the
     applicable Redemption Date, specifying the number of shares to be redeemed
     from such holder, the Redemption Date, the Redemption Price, the place at
     which payment may be obtained and calling upon such holder to surrender to
     the Corporation, in the manner and at the place designated, its
     certificates representing shares to be redeemed (the "Redemption Notice").
     Each holder of Series A Preferred Stock may, at any time prior to the
     Redemption Date (including during the period between its receipt of the
     Redemption Notice and the Redemption Date), convert all or part of its
     shares of Series A Preferred Stock into Common Stock in accordance with the
     terms of Section 5. Except as provided in Section 7(D), on or after the
     Redemption Date, each holder of Series A Preferred Stock to be redeemed
     shall surrender to the Corporation the certificate or certificates
     representing such shares, and thereupon the applicable Redemption Price of
     such shares shall be payable to the order of the person whose name appears
     on such certificate or certificates and each certificate shall be canceled.
     If less than all the shares represented by such certificate are redeemed, a
     new certificate shall be issued representing the unredeemed shares.
 
          (D) From and after each Redemption Date, unless there shall have been
     a default in payment of the Redemption Price, all rights of the holders of
     Series A Preferred Stock designated for redemption on such Redemption Date
     in the Redemption Notice as holders of Series A Preferred Stock (except the
     right to receive the applicable Redemption Price upon surrender of their
     certificate(s)) shall cease with respect to such shares, and such shares
     shall not thereafter be transferred on the books of this Corporation or be
     deemed to be outstanding for any purpose whatsoever. If the funds of this
     Corporation legally available for redemption of the Series A Preferred
     Stock on a Redemption Date are insufficient to redeem the total number of
     shares of Series A Preferred Stock to be redeemed on such date, those funds
     that are legally available will be used to redeem the maximum possible
     number of shares ratably among the holders of such shares to be redeemed
     such that each holder of a share of Series A Preferred Stock receives the
     same percentage of the applicable Series A Redemption Price. The shares of
     Series A Preferred Stock not redeemed shall remain outstanding and entitled
     to all the rights and preferences provided herein. Subject to the rights of
     the Series A Preferred Stock, which may from time to time come into
     existence, at any time thereafter when additional funds of the Corporation
     are legally available for the redemption of shares of Series A Preferred
     Stock, such funds will be immediately used to redeem the balance of the
     shares that this Corporation has become obligated to redeem on any
     Redemption Date but that it has not redeemed.
 
     Section 8. Protection Provisions. So long as at least 750,000 shares of
Series A Preferred Stock remain outstanding (as adjusted for stock splits,
reverse splits and other similar
 
 
                                       A-10
 
<PAGE>
 
events), the Corporation shall, not without first obtaining the approval (by
vote or written consent) of the holders of at least a majority of the then
outstanding shares of Series A Preferred Stock, issue additional shares of
capital stock with rights, preferences or privileges that are senior to or on a
parity with the Series A Preferred Stock.
 
     Section 9. 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 special rights of the Series A Preferred Stock so as to
affect them adversely without the written consent or affirmative vote of a
majority of the then outstanding shares of Series A Preferred Stock, voting
together as a single class.
