     Corporation  and its  stockholders  or any  class  of  them,  any  court of
     equitable jurisdiction within the State of Delaware may, on the application
     in a summary way of this  Corporation  or of any  creditor  or  stockholder

     (3/4) in value of the  creditors  or  class  of  creditors,  and/or  of the
     stockholders or class of stockholders of this Corporation,  as the case may
     be, agree to any compromise or  arrangement  and to any  reorganization  of

     the  creditors or class of  creditors,  and/or on all the  stockholders  or
     class of stockholders, of this Corporation, as the case may be, and also on
     this Corporation.

          SEVENTH: For the management of the business and for the conduct of the
     affairs of the  Corporation,  and in  further  definition,  limitation  and
     regulation of the powers of the Corporation and of its directors and of its
     stockholder  or any  class  thereof,  as the  case  may be,  it is  further
     provided:

          1. The  management  of the  business and the conduct of the affairs of
     the  Corporation  shall be vested in its Board of Directors.  The number of
     directors which shall constitute the entire Board of Directors





     shall  be fixed by, or in the manner  provided  in, the  Bylaws,  which
     number  has been set  initially  at not less than three nor more than nine,
     with the specific  number set by the Board of Directors  from time to time,
     and provided  further that the number of directors  constituting the entire
     Board shall be six until  otherwise fixed by a majority of the entire Board
     of Directors.  The phrase "entire Board of Directors" and the phrase "total
     number of directors" shall be deemed to have the same meaning,  to wit, the
     total number of directors which the Corporation would have if there were no
     vacancies. No election of directors need be by written ballot.

          2. After the  original or other  Bylaws of the  Corporation  have been
     adopted,  amended, or repealed,  as the case may be, in accordance with the
     provisions  of Section 109 of the General  Corporation  Law of the State of
     Delaware and, after the Corporation has received any payment for any of its
     stock,  the power to adopt,  amend, or repeal the Bylaws of the Corporation
     may be exercised by the Board of  Directors of the  Corporation;  provided,
     however,  that any  provision  for the  classification  of directors of the
     Corporation  for staggered  terms  pursuant to the provisions of subsection
     (d) of section 141of the General  Corporation  Law of the State of Delaware
     shall be set  forth in the  initial  Bylaws  or in  Bylaws  adopted  by the
     stockholders entitled to vote of the Corporation unless provisions for such
     classification shall be set forth in this certificate of incorporation.

          3.  Whenever the  Corporation  shall be  authorized  to issue only one
     class of stock,  each outstanding share shall entitle the holder thereof to
     notice of, and the right to vote at, any meeting of stockholders.  Whenever
     the Corporation  shall be authorized to issue more than one class of stock,
     no  outstanding  share of any class of stock which is denied  voting  power
     under the provisions of this Certificate of Incorporation shall entitle the
     holder thereof to the right to vote at any meeting of  stockholders  except
     as the  provisions  of  paragraph  (b)(2)  of  Section  242 of the  General
     Corporation Law of the State of Delaware shall otherwise require; provided,
     that no share of any such class  which is  otherwise  denied  voting  power
     shall  entitle the holder  thereof to vote upon the increase or decrease in
     the number of authorized shares of said class.

          EIGHTH:  The personal liability of the directors of the Corporation is
     hereby  eliminated to the fullest  extent  permitted by  subsection  (7) of
     subsection 9b) of Section 102 of the General  Corporation  Law of the State
     of Delaware, as the same may be amended and supplemented.

          NINTH:  The  Corporation  shall,  to the fullest  extent  permitted by
     Section 145 of the General Corporation Law of the State of Delaware, as the
     same may be amended and supplemented, indemnify any and all persons whom it
     shall have power to  indemnify  under said section from and against any and
     all of the expenses, liabilities or other matters referred to in or covered
     by said section,  and the indemnification  provided for herein shall not be
     deemed  exclusive  of any other  rights to which those  indemnified  may be
     entitled under any Bylaw, agreement,  vote of stockholders or disinterested
     directors or otherwise,  both as to action in his official  capacity and as
     to action in another capacity while holding such office, and shall continue





      as to a person who has ceased to be a director,  officer,  employee or
     agent  and  shall  inure  to  the  benefit  of  the  heirs,  executors  and
     administrators of such a person.

          TENTH: SERIES A CONVERTIBLE PREFERRED STOCK

          Section 1. Designation and Amount.

          The shares of such series shall be  designated as Series A Convertible

     Preferred Stock") and the initial number of shares constituting such series
     shall be 1,200,000.

          Section 2. Dividend Rights.

          The holders of shares of Series A Convertible Preferred Stock shall be

     dividends at the same rate and at the same time as any  dividends  declared
     on the Corporation's Common Stock, when, as and if declared by the Board of
     Directors;  provided  that,  for the purposes of this  Section 2 only,  the
     holders of the Series A Convertible  Preferred Stock shall be deemed to own
     the number of shares of Common  Stock  into  which such  shares of Series A
     Convertible  Preferred  Stock are  convertible at the time such dividend is
     declared.

        Section 3.    Voting Rights.

          (a) General. Except as otherwise required by law or expressly provided
     in this  Section 3, the  holders of Series A  Convertible  Preferred  Stock
     shall be entitled to notice of any  shareholders'  meeting and to vote upon
     any  matter  submitted  to  shareholders  for a  vote,  at any  time on the
     following basis:

               (i) Each holder of Series A Convertible  Preferred Stock shall be
          entitled for each share of Series A Convertible  Preferred  Stock held
          by such holder to the number of votes  equal to the highest  number of
          full  shares  of  Common  Stock  to  which  each  share  of  Series  A
          Convertible  Preferred  Stock is  convertible  pursuant  to  Section 5
          hereof  at the  record  date  for the  determination  of  shareholders
          entitled to vote on such matters; and

               (ii) Except as otherwise  required by law or  expressly  provided
          herein, the holders of Series A Convertible Preferred Stock and Common

          (i) So long as in excess of 35% of the Aggregate  Original  Amount (as
     defined in  Section  8) of Series A  Convertible  Preferred  Stock  remains
     outstanding,  the holders of the Series A Convertible Preferred Stock shall
     be entitled, voting as a separate class, to elect one





      (1)  director,  who  shall  be one  (1) of the  authorized  number  of
     directors of the Corporation. In the case of a vacancy in the office of the

     director by the affirmative vote of the holders of a majority of the Series
     A  Convertible   Preferred  Stock  given  at  a  special  meeting  of  such
     shareholders  duly called for that  purpose,  or by written  consent of the
     holders  of record of a  majority  of the  Series A  Convertible  Preferred

     office,  either  for or  without  cause,  by a  majority  of the  Series  A
     Convertible Preferred Stock given at a special meeting of such shareholders
     duly  called  for that  purpose,  or by written  consent of the  holders of
     record of a  majority  of the Series A  Convertible  Preferred  Stock.  Any
     vacancy  created  thereby  may  be  filled  by  the  holders  of  Series  A
     Convertible  Preferred  Stock  represented  at such  meeting  or by written
     consent  by holders of a  majority  of the Series A  Convertible  Preferred
     Stock.

          (c) Series A  Convertible  Preferred  Stock - Special  Voting  Rights.
     Provided that at least 35% of the Aggregate Original Amount of the Series A
     Convertible Preferred Stock remains outstanding,  the Corporation shall not

     holders  of at least a majority  of the shares of the Series A  Convertible
     Preferred Stock from time to time outstanding:

               (i) take any action that would  result in (A) a sale,  conveyance
          or other  disposition or distribution of all or  substantially  all of
          the assets of the Corporation or (B) merger, consolidation, or similar
          transaction with any other corporation or entity where the Corporation
          is not the survivor.

               (ii)  declare any  dividends  or any other  distributions  on, or
          redeem or repurchase any, Equity  Securities (as defined in Section 8)
          of  the   Corporation   of  any  nature  (except  for  any  dividends,
          redemptions  or  repurchases  required  by the terms of the  governing
          instrument for the related equity  securities which have been approved
          by the holders of the Series A Convertible Preferred Stock pursuant to
          Section 3(c)(iii) below);

               (iii) issue or authorize  the issuance of any shares of Preferred
          Stock or any warrant,  right,  option,  convertible  security or other
          security  which has  liquidation,  redemption  or dividend  preference
          rights  which are  senior to or on a parity  with the  preferences  or
          rights afforded to the Series A Convertible  Preferred Stock, or which
          has redemption, repurchase, put or similar rights;

               (iv) amend the  Corporation's  Certificate  of  Incorporation  or
          Bylaws; or

               (v)  make  or hold  any  direct  or  indirect  investment  in any
          corporation,  investment  in the  debt  or  equity  securities  of any
          corporation,  or  loans  or  guaranties  to one or  more  corporations
          involved in another business in excess of $1,000,000 in the aggregate.








     Section 4. Liquidation Preference.

          In the event of any voluntary or involuntary liquidation,  dissolution
     or  winding  up of the  affairs  of  the  Corporation  (any  such  event  a
     "Liquidation  Event")  then,  and in that  event,  the  holders of Series A
     Convertible  Preferred  Stock shall be entitled to receive  with respect to
     any such  Liquidation  Event prior and in preference to any distribution of
     any of the assets of the  Corporation  to the holders of Common Stock or to
     the  holders  of any  other  series of  preferred  stock by reason of their
     ownership  thereof,  an amount in cash or equivalent value in securities or
     other  consideration  equal to the "liquidation  preference" herein. If the
     amount of such  distribution  is insufficient to permit full payment of the
     "liquidation   preference"   herein,   then  such  distribution   shall  be
     distributed  ratably to the holders of the Series A  Convertible  Preferred
     Stock  on the  basis of the  number  of  shares  of  Series  A  Convertible
     Preferred Stock held. After payment in full of the "liquidation preference"
     owed to the  holders  of the  Series A  Convertible  Preferred  Stock,  the
     holders of the Common  Stock shall be  entitled,  to the  exclusion  of the
     holders  of the  Series  A  Convertible  Preferred  Stock,  to share in all
     remaining  assets of the  Corporation in accordance  with their  respective
     interests.

          For the  purposes  this Section 4, the term  "liquidation  preference"
     shall mean,  with respect to the Series A Convertible  Preferred  Stock, an
     amount equal to $6.25 per share (the Basic Preference  Amount") which Basic
     Preference  Amount  shall  increase at the rate of eight  percent  (8%) per
     share per year,  compounded annually on each subsequent  anniversary of the
     Series A Original  Issue Date (in the event of a Liquidation  Event between
     any such anniversaries,  the Basic Preference Amount increase for such year
     shall be prorated accordingly);

          Section 5. Conversion Rights.

          (a) Right to Convert Series A Convertible  Preferred Stock. Each share
     of Series A Convertible  Preferred Stock shall be convertible,  without the
     payment  of any  additional  consideration  and at the option of the holder
     thereof,  at any time after the Series A Original  Issue Date at the office
     of the  Corporation  (or any  transfer  agent for the Series A  Convertible
     Preferred Stock) into shares of Common Stock at the then effective Series A
     Conversion  Rate (as defined in Section  5(c) hereof) and adjusted on a per
     share basis giving effect to any adjustments required by Section 5 hereof.

          (b) Automatic Conversion. Each share of Series A Convertible Preferred
     Stock may, at the option of the  Corporation,  be converted  into shares of
     Common Stock at the then effective  Series A Conversion Rate (as defined in
     Section 5(c) hereof) and adjusted on a per share basis giving effect to any
     adjustments  required by Section 5 hereof  provided  that the shares of the
     Corporation's  Common  Stock trade at an Average  Price equal to or greater
     than $5.00 per share  (subject to any  adjustments  for events set forth in
     Section 5(e) through (i)) for 30 consecutive  trading days. The Corporation
     shall  give at least 20 days  prior  written  notice to the  holders of the
     Series  A  Convertible  Preferred  Stock  as to  any  automatic  conversion
     pursuant to this Section 5(b),  such  conversion  being  effective no later
     than the twenty (20) days following






      receipt by the holders of the Series   A Convertible  Preferred Stock of
     such notice; provided,  however, that nothing shall prohibit holders of the
     Series A Convertible Preferred Stock at any time, including after such time
     as the  Corporation  has given notice under this Section  5(b),  to convert
     their  Series A  Convertible  Preferred  Stock into shares of Common  Stock
     pursuant to Section 5(a).

          (c) Series A Conversion Rate.  Subject to the adjustments  provided in
     subsections  (e)  through  (i) of this  Section  5, each  share of Series A
     Convertible  Preferred  Stock shall be convertible  into five (5) shares of
     Common Stock

          (d) Mechanics of Conversion. Before any holder of Series A Convertible
     Preferred  Stock  shall be entitled to convert the same into full shares of
     Common Stock  pursuant to Section 5(a) hereof,  the holder shall  surrender
     the certificate or certificates  therefor,  duly endorsed, at the office of
     the  Corporation  or of any  transfer  agent for the  Series A  Convertible
     Preferred  Stock and shall give written  notice to the  Corporation at such
     office that such holder  elects to convert the same and shall state therein
     such  holder's  name or the  name or names of the  nominees  in which  such
     holder wishes the certificate or certificates for shares of Common Stock to
     be issued. The Corporation shall, as soon as practicable  thereafter but in
     no event later than four (4) business days after the  Corporation  receives
     all documents,  including notice and certificates,  necessary to effect the
     conversion  or, with respect to conversion  pursuant to Section 5(b) on the
     date specified in the notice (unless converted earlier),  issue and deliver
     at the address of such holder on the books and records of the  Corporation,
     or to such holder's nominee or nominees,  a certificate or certificates for
     the number of shares of Common Stock to which such holder shall be entitled
     as aforesaid,  together with cash in lieu of any fractional shares.  Except
     as otherwise  set forth in Section  5(b) above,  such  conversion  shall be
     deemed to occur  immediately  prior to the close of business on the date of
     surrender  of the  shares of  Series A  Convertible  Preferred  Stock to be
     converted,  and the person or  persons  entitled  to receive  the shares of
     Common Stock issuable upon conversion  shall be treated for all purposes as
     the record holder or holders of such shares of Common Stock on such date.

          Notwithstanding  anything to the  contrary  contained  herein,  if any
     holder of Series A  Convertible  Preferred  Stock  elects to  convert  such
     holder's  shares  at any  time  prior  to the  record  date  for any  vote,
     dividend,  redemption,  liquidation,  dissolution  or winding  up, or other
     actions for which a record date is set and the holder receives prior notice
     pursuant to Section 6, or prior to the effective date of any such event for
     which either no record date is set or respecting  which notice  pursuant to
     Section 6 is not received,  then for all purposes such conversion  shall be
     treated as having  occurred  prior to such date or  effective  date and the
     holder  shall be treated  as the owner of the Common  Stock into which such
     Series A Convertible Preferred Stock is convertible for all purposes.

          (e) Adjustments for Subdivisions and Combinations.  If the Corporation
     shall at any time,  or from time to time after the Series A Original  Issue
     Date,  effect a subdivision of the outstanding  Common Stock,  the Series A
     Conversion Rate then in effect immediately before




      such subdivision shall be   proportionately  increased,  and conversely,
     if the Corporation  shall at any time or from time to time after the Series
     A Original Issue Date combine the outstanding  shares of Common Stock,  the
     Series A Conversion Rate then in effect immediately before such combination
     shall be proportionately  decreased. Any adjustment under this Section 5(e)
     shall  become  effective  at  the  close  of  business  on  the  date  such
     subdivision or combination becomes effective.

          (f) Adjustments for Certain Dividends and Distributions.  In the event
     the  Corporation  at any  time,  or from time to time  after  the  Series A
     Original  Issue  Date,  shall  make or issue  or fix a record  date for the
     determination  of holders of Common Stock entitled to receive a dividend or
     other  distribution  payable in additional shares of Common Stock, then and
     in each such event the  Series A  Conversion  Rate then in effect  shall be
     increased  as of the time of such  issuance  or, in the event such a record
     date shall have been  fixed,  as of the close of  business  on such  record
     date,  by  multiplying  the  Series A  Conversion  Rate then in effect by a
     fraction:

               (i) the numerator of which shall be the total number of shares of
          Common Stock issued and outstanding  immediately  prior to the time of
          such  issuance  or the close of  business on such record date plus the
          number of shares of Common Stock  issuable in payment of such dividend
          or distribution; and

               (ii) the denominator of which shall be the total number of shares
          of Common Stock issued and outstanding  immediately  prior to the time
          of such  issuance  or the  close  of  business  on such  record  date;
          provided,  however, if such record date shall have been fixed and such
          dividend is not fully paid or if such  distribution  is not fully made
          on the date  fixed  therefor,  the Series A  Conversion  Rate shall be
          recomputed accordingly as of the close of business on such record date
          and thereafter the Series A Conversion Rate shall be adjusted pursuant
          to  this  Section  5(f)  as of the  time  of  actual  payment  of such
          dividends or distributions.

          (g) Adjustment for Other Dividends and Distributions. In the event the
     Corporation  at any time,  or from time to time after the Series A Original
     Issue Date shall make or issue, or fix a record date for the  determination
     of  holders of Common  Stock  entitled  to  receive,  a  dividend  or other
     distribution  payable in securities of the Corporation other than shares of
     Common Stock (but including securities convertible into Common Stock), then
     and in each such  event  provisions  shall be made so that the  holders  of
     Series A Convertible Preferred Stock shall receive upon conversion thereof,
     in addition to the number of shares of Common Stock  receivable  thereupon,
     the amount and type of securities of the  Corporation  that they would have
     received  on a per share  basis had their  Series A  Convertible  Preferred
     Stock been  converted  into Common  Stock on the date of such event and had
     such holders  thereafter,  during the period from the date of such event to
     and including the conversion date,  retained such securities  receivable by
     them as aforesaid during such period giving  application to all adjustments
     called for during  such  period  under this  Section 5 with  respect to the
     rights of the holders of the Series A Convertible Preferred Stock.






          (h) Adjustments for Reclassification, Exchange or Substitution. If the
     Common  Stock  issuable  upon the  conversion  of the Series A  Convertible
     Preferred  Stock shall be changed  into the same or a  different  number of
     shares of any class or  classes  of stock of the  Corporation,  whether  by
     capital  reorganization,  reclassification  or  otherwise  (other than by a
     subdivision, a combination or a stock dividend as provided for elsewhere in
     this  Section 5), then and in each event the holder of each share of Series
     A Convertible  Preferred  Stock shall have the right  thereafter to convert
     such share into the kind and amount of shares of stock or other  securities
     and property receivable upon such reorganization, reclassification or other
     change by the  holders of the  number of shares of Common  Stock into which
     each such share of Series A  Convertible  Preferred  Stock  might have been
     converted  immediately prior to such  reorganization,  reclassification  or
     other change,  all subject to further  adjustment as provided  elsewhere in
     this Section 5.

               (i) Sale of Shares  Below  Dilution  Price.  For purposes of this
          Section  5(i),  the  Dilution  Price shall be  initially  equal to one
          dollar and twenty-five cents ($1.25)..

                    (a) If at any time after the Series A Original  Issue  Date,
               the  Corporation  shall  issue  for cash or  other  consideration
               shares  of  Common  Stock  or any  security  convertible  into or
               exchangeable or exercisable for shares of Common Stock at a price
               per share of Common Stock  calculated  by including the aggregate
               proceeds  per  share to the  Corporation  upon  issuance  and any
               additional  consideration  per share  payable to the  Corporation
               upon any such  conversion,  exchange  or  exercise  (in each case
               before  deduction of any per share discounts,  commissions,  fees
               and other  expenses of issuance and  marketing),  (the "New Issue
               Price),  that is less than the Dilution Price then in effect, the
               Dilution  Price shall be  automatically  adjusted down to the new
               Issue Price and the  aggregate  number of shares of Common  Stock
               issuable upon the  conversion of each share of Series A Preferred
               Stock  shall  be  automatically  adjusted  to  equal  the  result
               obtained by dividing the initial Purchase Price of $6.25 for each
               share of Series A Preferred  Stock by the New Issue Price. In the
               event that this  Section  5(i)  applies,  the Series A Conversion
               Rate shall determined by this Section 5(i)(a).

                    For example,  assume that (i) the Series A  Conversion  Rate
               was five (5) shares of Common  Stock for each share of  Preferred
               Stock;  (ii) the initial  Purchase Price was $6.25 per share, and
               (iii) the Purchaser had acquired 100 shares of Series A Preferred
               Stock for an  aggregate  purchase  price of  $625.00.  If the New
               Issue Price is $.50 per share,  the new  Dilution  Price would be
               $.50 per share and each share of Series A  Preferred  Stock would
               be convertible into 12.5 shares of Common Stock.

                    (b) For the purpose of this  Section  5(i),  the issuance by
               the Corporation of securities convertible into or exchangeable or
               exercisable  for  Common  Stock  shall be deemed to  involve  the
               immediate  issuance  of the  maximum  number  of shares of Common
               Stock issuable upon the conversion,  exchange or exercise of such
               securities  for a  consideration  equal to the minimum  aggregate
               consideration receivable by the Corporation upon such conversion,
               exchange or exercise.  In the event that securities are issued by
               the Corporation that result in an adjustment to





                the Series A Conversion  Rate  pursuant to this Section 5(i)
               and such  securities  are not  converted,  exchanged or exercised
               prior  to the  expiration  of the  right of the  holders  of such
               securities to effect any such action,  then immediately upon such
               expiration  of the right of the  holders  of such  securities  to
               effect any such action, the Series A Conversion Rate and Dilution
               Price shall be  recomputed  (but such  redetermination  shall not
               affect  the  Series A  Conversion  Rate of any shares of Series A
               Preferred   Stock  that  have  been   converted   prior  to  such
               expiration)  and effective  immediately  upon such expiration the
               Dilution Price and Series A Conversion Rate shall be increased to
               the ratio  which it would  have been  (but  reflecting  and other
               adjustments  in the Series A  Conversion  Rate made  pursuant  to
               other  provisions  of this  Section 5 after the  issuance of such
               securities) had such  adjustments to the Series A Conversion Rate
               and Dilution Price not been made.

                    (j) Issue Taxes. The Corporation shall pay any and all issue
               and other  taxes  that  maybe  payable in respect of any issue or
               delivery  of shares of Common  Stock on  conversion  of shares of
               Series A Convertible Preferred Stock,  excluding any tax or other
               charge  imposed in connection  with any transfer  involved in the
               issue and delivery of shares of Common Stock in a name other than
               that in which the shares of Series A Convertible  Preferred Stock
               so converted were registered,  which tax or charge shall be borne
               by the transferor.

                    (k) Reservation of Stock. The Corporation shall at all times
               reserve and keep  available  out of its  authorized  but unissued
               shares of Common Stock  solely for the purpose of  effecting  the
               conversion  of the shares of the Series A  Convertible  Preferred
               Stock one and  one-half  times the number of its shares of Common
               Stock as shall  from time to time be  sufficient  to  effect  any
               conversion  of any or all  outstanding  shares  of the  Series  A
               Convertible  Preferred  Stock.  If at  any  time  the  number  of
               authorized  but  unissued  shares  of Common  Stock  shall not be
               sufficient  to  effect  the  conversion  of all then  outstanding
               shares  of  the  Series  A  Convertible   Preferred   Stock,  the
               Corporation  shall  take such  corporate  action  as may,  in the
               opinion of its counsel,  be necessary to increase its  authorized
               but  unissued  shares of Common Stock to such number of shares as
               shall be sufficient for such purpose.

                    (l) Fractional  Shares.  No fractional share shall be issued
               upon  the   conversion  of  any  share  or  shares  of  Series  A
               Convertible   Preferred   Stock.   All  shares  of  Common  Stock
               (including  fractions)  issuable upon conversion of more than one
               share of Series A Convertible Preferred Stock by a holder of such
               stock shall be aggregated for purposes of determining whether the
               conversion would result in the issuance of any fractional  share,
               if,  after  aggregation,  the  conversion  would  result  in  the
               issuance of a fractional  share of Common Stock,  the Corporation
               shall,  in lieu of issuing any fractional  share,  pay the holder
               otherwise  entitled  to such  fraction a sum in cash equal to the
               fair market value of such fraction on the date of conversion  (as
               determined in good faith by the Board of Directors).

                    (m) Successive Changes. The above provisions of this Section
               5 shall similarly apply to successive combinations, subdivisions,
               dividends and  distributions  on or of the Common Stock after the
               Series A Original Issue Date.







                    (n)  Subsequent Events. On the Series A Original Issue Date,
                         and  thereafter,  from  time to time,  within  ten (10)
                         Business  Days of the  occurrence  of any  event  which
                         would  have  the  result  of  changing   the  Series  A
                         Conversion  Rate,  the  Corporation  shall  notify  the
                         holders of the Series A Convertible  Preferred Stock of
                         the  nature of such  event and of the newly  calculated
                         figures  resulting from such change and the calculation
                         in reasonable detail.

     Section 6. Notices of Record Date.

          In the event of (i) any taking by the  Corporation  of a record of the
     holders of any class or series of securities for the purpose of determining
     the  holders  thereof who are  entitled  to receive  any  dividend or other
     distribution  or  (ii)  any  reclassification  or  recapitalization  of the
     capital  stock  of  the   Corporation   or  any  voluntary  or  involuntary
     dissolution,  liquidation or winding up of the affairs of the  Corporation,
     the  Corporation  shall send by (1) personal  delivery to such holder,  (2)
     first class mail addressed, postage prepaid, and addressed to the holder at
     the address appearing on the books of the Corporation,  or (3) facsimile to
     such  holder  at the  facsimile  number  provided  by  such  holder  to the
     Secretary  of the  Corporation,  at least ten (10) days prior to the record
     date specified  therein, a notice specifying (A) the date on which any such
     record  is  to  be  taken  for  the  purpose  of  such  dividend  or  other
     distribution  and a description of such dividend or  distribution,  (B) the
     date on  which  any  such  reorganization,  reclassification,  dissolution,
     liquidation  or winding up is  expected  to become  effective,  and (C) the
     time,  if any is to be fixed,  as to when the holders of record of Series A
     Convertible  Preferred  Stock shall be entitled to exchange  their Series A
     Convertible  Preferred  Stock for securities or other property  deliverable
     upon such  reorganization,  reclassification,  dissolution,  liquidation or
     winding up. For purposes of this notice  provision,  notice shall be deemed
     to have been  given  (1) the next day in the case of  notice by a  national
     courier  service,  or  (2) in the  case  of  facsimile,  upon  sending  the
     facsimile.

        Section 7. Reacquired Shares.

          Any  shares  of  Series  A  Convertible   Preferred  Stock  converted,
     purchased or otherwise acquired by the Corporation in any manner whatsoever
     shall be retired and cancelled promptly after the acquisition thereof, and,
     if necessary to provide for the lawful purchase of such shares, the capital
     represented by such shares shall be reduced in accordance  with the General
     Corporation Law of the State of Delaware.  All such shares shall upon their
     cancellation  become  authorized  but unissued  shares of Preferred  Stock,
     $.001 par value,  of the Corporation and may be reissued as part of another
     series of Preferred Stock, $.001 par value, of the Corporation.
