            1.5. Prepayment. The Corporation may at its option from time to time
      prepay  this Note in whole or in part,  without  any  prepayment  penalty.
      Notwithstanding  anything  to  the  contrary  contained  herein,  no  such

      conversion rights hereunder.

      in part at Holder's  option upon the receipt by the Corporation of cash or
      cash  equivalents  from any source after the date hereof from the purchase
      of equity  securities  of the  Corporation,  whether in the form of common
      stock  or  preferred  stock,  or the  purchase  of any  security  which is
      convertible to or  exerciseable  or otherwise  exchangeable  for an equity
      security of the Corporation,  ("Additional  Capital").  Additional Capital

      the exercise of the Sunrise  Investors'  Warrants to purchase an aggregate

      Million and no/100 Dollars  ($4,000,000.00)  or more of Additional Capital
      (the "Initial Acceleration Additional Capital") the Holder may require the
      Initial  Acceleration  in  the  payment  of  the  outstanding  balance  of
      principal and accrued interest in a percentage  calculated by dividing the
      Initial Acceleration  Additional Capital by eight million (8,000,000).  In
      the event that the Corporation shall receive  Additional Capital after the
      Holder has exercised the right to make an Initial Acceleration, the Holder
      shall be  entitled  to  accelerate  the  payment  of the then  outstanding
      balance of principal and accrued interest in accordance with the following
      schedule:

              Amount of Additional Capital              Percentage of Remaining
              In Excess of Initial Acceleration         Note Principal Balance
              Additional Capital                        Subject to Acceleration

                       3,000,000                                 100%

      connection  with the  settlement  of  certain  litigation  between,  among
      others, the Corporation and the Holder.

            3. Events of Default;  Consequences.  If any of the events specified
      in this  Section 3 shall  occur  (herein  individually  referred  to as an
      "Event of Default"),  the Holder of this Note may, at the Holder's option,
      in  addition  to any other  rights the Holder may have in equity or at law
      and in addition to the Holder's  rights of  conversion  under Section 7 of

      of  this  Note  into   fully  paid  and   non-assessable   shares  of  the
      Corporation's  common stock,  with $.001 par value per share, (the "Common
      Stock"), on the basis of one (1) share of Common Stock for each One Dollar
      ($1.00) (the "Conversion Price") of the principal amount of this Note. The
      Conversion Price and the corresponding number of shares of Common Stock to
      be issued upon the  conversion of this Note shall be subject to adjustment
      from time to time upon the  occurrence of certain  events,  as provided in
      this Note.  The prepayment of this Note, in whole or in part prior to 5:00
      p.m.,  Chicago  time of the First  Installment  Date  shall not reduce the

      Stock on the basis of one share of Common Stock for the Conversion  Price.
      The  Conversion  Price  and the  corresponding  number of shares of Common
      Stock to be issued  upon the  conversion  of this Note shall be subject to
      adjustment  from time to time upon the  occurrence of certain  events,  as
      provided in this Note. The  prepayment of this Note,  shall not reduce the
      amount of this Note which may be converted into Common Stock in accordance
      with this Section 7.1.b.


                                       4


            7.2 Conversion  Procedure.  Such conversion shall be effected by (i)
      the surrender of this Note at the principal  office of the  Corporation at
      any time during usual  business  hours,  together  with (ii) five (5) days
      notice in writing  that the  Holder  wishes to convert a portion or all of
      this Note,  which notice shall also state the name(s) (with addresses) and
      denominations in which the certificate(s) for Common Stock shall be issued
      and  shall   include   instructions   for   delivery   thereof  and  (iii)
      reimbursement  without  interest for any previous  payment of principal by
      the Corporation which is being converted.  Such conversion shall be deemed
      to have been  effected  as of the close of  business  on the date on which
      this Note  shall have been  surrendered  and such  notice  shall have been
      received, and at such time (the "Voluntary Conversion Date") the rights of
      the Holder  with  respect to the  principal  amount of the Note  converted
      shall cease and the  person(s)  in whose  name(s) any  certificate(s)  for
      Common Stock are to be issued upon such conversion shall be deemed to have
      become  the  holder or  holders  of record of the  shares of Common  Stock
      represented by such certificate(s).

            On  or  before  the  third  business  day  following  the  Voluntary
      Conversion  Date,  the  Corporation  shall (i) provided  that the transfer
      agent for the Corporation is participating in The Depository Trust Company
      ("DTC") Fast Automated  Securities  Transfer Program,  upon the request of
      Holder,  credit  such  aggregate  number of Shares to which the  Holder is
      entitled  pursuant  to  such  conversion  to  the  Holders'  or his or its
      designee's  balance account with DTC though its Deposit  Withdrawal  Agent
      Commission  system,  or (ii) if the  Corporation's  transfer  agent is not
      participating in the DTC Fast Automated Securities Transfer Program, issue
      and dispatch, or cause to be issued and dispatched by overnight courier to
      the  address  as  specified  in  the  written  notice  of  conversion,   a
      certificate,  registered in the name of the Holder or his or its designee,
      for the number of Shares to which the Holder is entitled  pursuant to such
      conversion.  The  Corporation  shall  also make  payment  to the Holder of
      accrued  interest  to the date of  conversion  on the  portion of the Note
      converted in accordance with the manner of payment provisions of Section 2
      of this Note. In each case of  conversion  of this Note in part only,  the
      Corporation  shall  receive and hold the Note as a fiduciary  agent of the
      Holder,  shall  endorse  on this Note the date and  amount of this Note so
      converted,  and such amount shall be deemed no longer outstanding.  Unless
      this Note has been converted in its entirety and all principal and accrued
      interest have been fully-paid, this Note, endorsed as provided for herein,
      shall be  delivered  on or before the third  business  day  following  the
      Voluntary  Conversion  by  overnight  courier to the Holder at the address
      specified in the written  notice of  conversion.  The rights of conversion
      provided for in this Note shall not be  restricted  or modified in any way
      during  such  period of time that  this Note is held by  Corporation.  The
      Corporation  shall not be required to issue  shares of Common Stock to any
      individual  or entity upon  conversion  of this Note unless and until said
      individual  or entity shall have  completed a  Subscription  Agreement and
      Investor  Questionnaire  substantially  in the  forms  attached  hereto as
      EXHIBIT 1 and 2, respectively.

            7.3. Adjustment of Conversion Price. If and whenever on or after the
      date of this  Note,  the  Corporation  issues,  sells or grants  shares of
      Common Stock in, or in accordance  with Sections 7.4, 7.5 and 7.6 below is
      deemed to have  issued,  sold or  granted  shares of Common  Stock in, the
      Corporation for no consideration or for  consideration per share of Common
      Stock less than the Conversion  Price in effect  immediately  prior to the
      time of such  issuance or sale,  then and in such event,  such  Conversion
      Price  shall  be  reduced,  concurrently  with  such  issue,  to  a  price
      (calculated to the nearest cent) determined by multiplying such Conversion
      Price by a fraction,  the numerator of which shall be the number of shares
      of Common  Stock  outstanding  immediately  prior to such  issue  plus the
      number  of  shares  of Common  Stock  which  the  aggregate  consideration
      received by the Corporation  for the total number of additional  shares of
      Common Stock so issued or deemed to be issued, would purchase when divided
      by such Conversion Price; and the denominator of which shall be the number
      of shares of Common Stock  outstanding  immediately prior to such issuance
      plus the  number of such  additional  shares of Common  Stock so issued or
      deemed to be issued.


                                       5


            7.4.  Issuance and Sale of Shares of Common  Stock.  For purposes of
      determining the adjusted  Conversion  Price pursuant to Section 7.3 above,
      the following  events shall be deemed to be an issuance and sale of shares
      of Common Stock by the Corporation:

                  (a) Issuance of Rights or Options. If (i) the Corporation,  in
            any manner, hereafter grants any rights or options to subscribe for,
            or  to  purchase,   shares  of  Common  Stock,   or  any  securities
            convertible  into or exchangeable  for any shares of Common Stock of
            the  Corporation  (such  rights  or  options  referred  to herein as
            "Options" and such convertible or exchangeable  securities  referred
            to herein as "Convertible  Securities")  and (ii) the Price Per Unit
            (as defined  below) of the shares of Common Stock  issuable upon the
            exercise  of such  Options or upon  conversion  or  exchange of such
            Convertible  Securities is less than the Conversion  Price in effect
            immediately  prior to the time of the  granting  of such  Options or
            issuing such Convertible Securities, then the shares of Common Stock
            issuable  upon the  exercise of such Options or upon  conversion  or
            exchange of such Convertible  Securities will be deemed to have been
            issued and sold by the  Corporation  for such lesser price per unit.
            For the  purposes  of this  Section  7.4(a)  the "Price Per Unit" is
            determined by dividing (i) the total amount, if any, received by the
            Corporation  as  consideration  for the  granting of such Options or
            issuing  such  Convertible  Securities,  plus the minimum  aggregate
            amount of additional  consideration  payable to the Corporation upon
            exercise of all such Options, plus in the case of such Options which
            relate to Convertible  Securities,  the minimum  aggregate amount of
            additional  consideration,  if any,  payable to the Corporation upon
            the  issuance  or  sale  of  such  Convertible  Securities  and  the
            conversion or exchange thereof,  by (ii) the total maximum number of
            shares of Common Stock issuable upon the exercise of such Options or
            upon the conversion or exchange of all such Convertible  Securities.
            No  further  adjustment  of the  Conversion  Price will be made when
            Convertible Securities are actually issued upon the exercise of such
            Options or when shares of Common Stock are actually  issued upon the
            exercise  of such  Options or the  conversion  or  exchange  of such
            Convertible Securities.

                  (b) Calculation of  Consideration  Received.  If any shares of
            Common Stock in the Corporation,  Options or Convertible  Securities
            are  issued or sold or deemed to have been  issued or sold for cash,
            the  consideration  received  therefor or the Price Per Unit, as the
            case may be,  will be deemed to be the net amount  received or to be
            received,  respectively,  by the Corporation  therefor.  In case any
            shares of Common Stock in the  Corporation,  Options or  Convertible
            Securities are issued or sold for a  consideration  other than cash,
            the  amount of the  consideration  other than cash  received  by the
            Corporation  or the non-cash  portion of the Price Per Unit,  as the
            case may be,  will be the fair  market  value of such  consideration
            received or to be received, respectively, by the Corporation. If any
            shares of Common Stock in the  Corporation,  Options or  Convertible
            Securities  are  issued in  connection  with any merger in which the
            Corporation   is  the   surviving   Corporation,   the   amount   of
            consideration  therefor  will be deemed to be the fair value of such
            portion  of  the  net  assets  and  business  of  the  non-surviving
            Corporation  as is  attributable  to such  shares of  Common  Stock,
            Options  or  Convertible  Securities,  as the case may be.  The fair
            value of any consideration other than cash and marketable securities
            will be determined  jointly by the  Corporation  and the Holder.  If
            such  parties  are  unable to reach  agreement  within a  reasonable
            period  of  time,  the  fair  value  of such  consideration  will be
            determined  by an  independent  appraiser  jointly  selected  by the
            Corporation and the Holder.


                                       6


                  (c) Integrated  Transactions.  In case any Option is issued in
            connection  with the  issuance  or sale of other  securities  of the
            Corporation, together comprising one integrated transaction in which
            no specific consideration is allocated to such Option by the parties
            thereto,  the  Option  will be  deemed  to have  been  issued  for a
            consideration of $.01.

                  (d)  Record  Date.  If the  Corporation  takes a record of the
            holders of Common  Stock for the purpose of entitling  them:  (i) to
            receive a dividend or other distribution payable in shares of Common
            Stock in the Corporation, Options or Convertible Securities; or (ii)
            to  subscribe  for  or  purchase  shares  of  Common  Stock  in  the
            Corporation,  Options or  Convertible  Securities,  then such record
            date will be deemed  to be the date of the  issuance  or sale of the
            shares of Common  Stock  deemed to have been issued or sold upon the
            declaration  of such  dividend  or upon  the  making  of such  other
            distribution   on  the  date  of  the  granting  of  such  right  of
            subscription or purchase, as the case may be.

            7.5.  Subdivision or  Combination of Shares of Common Stock.  If the
      Corporation at any time  subdivides one or more classes of its outstanding
      shares of Common Stock into a greater number of shares of Common Stock (or
      units thereof),  the Conversion Price in effect  immediately prior to such
      subdivision  will be  proportionately  reduced.  If the Corporation at any
      time  combines  one or more  classes of its  outstanding  shares of Common
      Stock  into a smaller  number of shares of Common  Stock,  the  Conversion
      Price  in  effect   immediately   prior  to  such   combination   will  be
      proportionately increased.

            7.6 Organic Change.  Exclusive of the merger between  Technology and
      the  Corporation,  prior to the  consummation  of any  Organic  Change (as
      defined below), the Corporation will make appropriate  provisions (in form
      and  substance  satisfactory  to Holder) to insure that the holder of this
      Note will thereafter have the right to acquire and receive,  in lieu of or
      in addition to the shares of Common Stock in the  Corporation  immediately
      theretofore  acquirable and  receivable  upon the conversion of this Note,
      such  shares  of  stock,  membership  interests,   partnership  interests,
      securities or assets as such holder would have received in connection with
      such  Organic  Change if the holder had  converted  this Note  immediately
      prior to such Organic Change.  In any such case, the Corporation will make
      appropriate  provisions (in form and substance  satisfactory to Holder) to
      insure  that  the  provisions  of this  Section  7.6  will  thereafter  be
      applicable  to  this  Note  (including,  an  immediate  adjustment  of the
      Conversion  Price to the  value  for the  shares  of  Common  Stock in the
      Corporation   reflected  by  the  terms  of  such  Organic  Change  and  a
      corresponding immediate adjustment in the number of shares of Common Stock
      acquirable  and receivable  upon  conversion of this Note, if the value so
      reflected is less than the Conversion Price in effect immediately prior to
      such Organic  Change).  The  Corporation  will not effect any such Organic
      Change,   unless  prior  to  the  consummation   thereof,   the  successor
      Corporation   resulting  from  such  Organic  Change  assumes  by  written
      instrument (in form reasonably  satisfactory to Holder), the obligation to
      deliver to each such holder such shares of stock, securities or assets as,
      in accordance with the foregoing  provisions,  such holder may be entitled
      to acquire.  All other  terms of this Note shall  remain in full force and
      effect  following such an Organic  Change.  The provisions of this Section
      7.6 shall similarly apply to successive Organic Changes.


                                       7


            As used herein,  the term  "Organic  Change"  shall mean any merger,
      consolidation, combination, recapitalization, reorganization, stock split,
      stock  dividend  or other  change  in, or with  respect  to, the shares of
      Common Stock in the Corporation not otherwise provided for herein.

            7.7. Other Distributions. If the Corporation declares a distribution
      for its  shareholders  of Common Stock,  which  distribution is payable in
      securities  of other  parties,  evidences  of  indebtedness  issued by the
      Corporation or other parties, assets (excluding cash dividends) or options
      or rights not referred to in Section 7.4,  then, in each such case for the
      purposes  of  this  Section  7.7,  the  Holder  shall  be  entitled  to  a
      proportionate  share of any such distribution as though the Holder was the
      holder of the  number of shares  of Common  Stock  into  which the Note is
      convertible  as of the  record  date  fixed for the  determination  of the
      holders of Common Stock entitled to receive such distribution. In no event
      shall such a  distribution  be deemed a repayment of  principal  under the
      Note.

            7.8.  New  Financing.   Notwithstanding  anything  to  the  contrary
      contained herein, in the event the Corporation sells any security (equity,
      debt or otherwise) of the Corporation  ("New  Security") at any time while
      this Note is outstanding ("New  Financing"),  this Note shall,  after such
      New Financing, be convertible,  at the option of the Holder, into the kind
      and number of shares of the New  Security,  on such  terms and  conditions
      (including any warrants or other consideration  received by the purchasers
      in the New  Financing)  as the New Security is sold in the New  Financing,
      subject to all of the terms of the New Financing.  The  conversion  rights
      set forth in this Section 7.8 are in addition to, and not in  substitution
      for, the other conversion rights set forth in this Note.

            7.9. Notices.

            (a)  Immediately  upon any  adjustment  in the  number  of shares of
      Common Stock acquirable and receivable upon conversion of this Note or any
      adjustment or readjustment in the Conversion  Price, the Corporation shall
      send  written  notice  to the  Holder,  which  notice  shall  set forth in
      reasonable  detail the method of calculation and the facts upon which such
      calculation is based. The Corporation  shall,  upon written request at any
      time of the  Holder,  furnish or cause to be  furnished  to such  holder a
      similar  certificate setting forth (i) such adjustments and readjustments,
      (ii) the Conversion  Price then in effect,  and (iii) the number of shares
      of Common Stock and the amount, if any, of other property which then would
      be received upon the conversion of this Note. The Corporation may retain a
      firm of independent public accountants of recognized standing which may be
      the firm regularly  retained by the  Corporation  to make any  computation
      required under this Section and a certificate signed by such firm shall be
      rebuttable  evidence of the correctness of any computation made under this
      Section.


                                       8


            (b) In the event that:

                  (i) the Corporation shall declare any dividend or distribution
            upon its Common  Stock,  whether in cash,  property,  stock or other
            securities,  whether or not a regular  cash  dividend and whether or
            not out of earnings or earned surplus; or

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

                  (iii) there shall be any Organic Change; or

                  (iv) there shall be any voluntary or involuntary  dissolution,
            liquidation or winding up of the Corporation;

then in  connection  with each such  event,  the  Corporation  shall send to the
Holder (A) at least 60 days' prior written notice of the date on which the books
of the  Corporation  shall close or a record  shall be taken for such  dividend,
distribution  or  subscription  rights  (and  specifying  the date on which  the
holders of Common Stock shall be entitled) or for determining  rights to vote in
respect of such Organic Change, dissolution,  liquidation or winding up, and (B)
in the case of any such Organic Change, dissolution,  liquidation or winding up,
at least 60 days'  prior  written  notice of the date when the same  shall  take
place (and  specifying  the date on which the  holders of Common  Stock shall be
entitled  to  exchange  their  Common  Stock for  securities  or other  property
deliverable upon such Organic Change, dissolution, liquidation or winding up).

      8. Registration  Rights. The Corporation grants registration rights to the
Holder  hereof  under  the  terms  and  conditions  of the  Registration  Rights
Agreement of even date herewith.

      9. Reservation of Common Stock; Etc.

            (a) The  Corporation  will at all  times  from and after the date of
      this Note reserve and keep  available out of its  authorized  but unissued
      shares of Common Stock or its treasury  shares,  or otherwise,  solely for
      the purpose of issuance upon the  conversion of this Note,  such number of
      shares of Common Stock as shall then be issuable  upon the  conversion  of
      this Note. The Corporation covenants that all shares of Common Stock which
      shall be so issuable shall, when issued, be duly and validly issued, fully
      paid and non-assessable and free from all taxes, liens and charges.


                                       9


            (b) The  Corporation  will not take any action which would result in
      any  adjustment  of the number of shares of Common Stock  acquirable  upon
      conversion of this Note if the total number of shares  issuable after such
      action upon  conversion  of this Note,  together  with the total number of
      shares of Common Stock then outstanding,  would exceed the total number of
      shares of Common Stock then authorized under the Corporation's Articles of
      Incorporation  which are not  reserved or required to be reserved  for any
      purpose other than the purpose of issue upon conversion of this Note.

            (c) The  issuance of  certificates  for shares of Common  Stock upon
      conversion of this Note shall be made without charge to the Holder for any
      issuance tax or other cost incurred by the  Corporation in connection with
      such conversion and the related issuance of shares of Common Stock.

            (d) If any  shares of  Common  Stock  required  to be  reserved  for
      purposes of  conversion  of this Note  require,  before such shares may be
      issued upon conversion,  registration with or approval of any governmental
      authority  under any  federal  or state law (other  than any  registration
      under  the  Securities  Act of 1933,  as then in  effect,  or any  similar
      federal  statute then in force, or any state  securities law,  required by
      reason of any  transfer  involved  in such  conversion)  or listing on any
      domestic securities exchange,  the Corporation will, at its expense and as
      expeditiously as possible, use its best efforts to cause such shares to be
      duly  registered  or  approved  for  listing  or listed  on such  domestic
      securities exchange, as the case may be.

      10. Fractional  Interests.  The Corporation shall not be required to issue
      any  fractional  shares of Common Stock on the conversion of this Note. If
      any fraction of a share of Common Stock would be issuable upon  conversion
      of this Note, the Corporation shall round up and issue one (1) whole share
      in lieu of a fractional share.

      11.  Security  Agreement.  The  Corporation  hereby  acknowledges  that in
      connection  with  executing this Note,  the  Corporation  and Holder shall
      enter into a Security Agreement  substantially in the form attached hereto
      as Exhibit 11 whereby  the  Corporation  shall  grant to Holder a security
      interest in its assets as set forth therein.

      12.  Voting.  Nothing  contained  in  this  Note  shall  be  construed  as
      conferring  upon the  Holder the right to vote or to consent or to receive
      notice as a stockholder in respect of the meetings of stockholders for the
      election  of  directors   of  the   Corporation   or  any  other   matter.
      Notwithstanding  the foregoing,  the Corporation shall mail by first class
      to the Holder at the  address  specified  in  Section  13, one copy of all
      materials  forwarded  to  stockholders  or filed with the  Securities  and
      Exchange  Commission by the Corporation,  said mailing to be made promptly
      after mailing to  stockholders  or filing with the Securities and Exchange
      Commission, as the case may be.
