               the  Securities  or the  shares  issuable  upon  exercise  of the
               Warrants, or any interest therein,  except in accordance with the
               Securities   Act  and  the  applicable   rules  and   regulations
               promulgated thereunder, as then in force, and any applicable law,
               rule or  regulation  of any state or other  jurisdiction  ("State
               Laws").

     (b)  The undersigned further understands and agrees that:

          (i)  The  Securities  and the shares  issuable  upon  exercise  of the
               Warrants have not been registered under the Securities Act or the
               State  Laws and,  consequently,  the  Securities  and the  shares
               issuable upon exercise of the Warrants must be held  indefinitely
               unless  subsequently  registered  thereunder or an exemption from
               such  registration is available.  The undersigned  shall register
               the  Securities  and the shares  issuable  upon  exercise  of the
               Warrants as soon as practically possible following the closing of
               the  Pivotal  Transaction  but no later  than 90 days  after  the
               closing of the Pivotal Transaction so that the Securities and the
               shares underlying the Warrant may be publicly offered.

          (ii) The  Securities  and the shares  issuable  upon  exercise  of the
               Warrants have not been registered under the Securities Act on the
               basis that the issuance  thereof is exempt under  Section 3(b) or

               ("Regulation  D") under the Securities Act and that the Company's
               reliance  on  such   exemption  is  predicated  in  part  on  the

               Subscription  Agreement.  The Securities and the shares  issuable
               upon  exercise of the  Warrants  have not been  registered  under

               registration  thereunder and no securities  administrator  or any
               state  or  the  Federal   government  has  made  any  finding  or
               determination  relating to the  fairness  for  investment  of the
               Securities  or the shares  issuable upon exercise of the Warrants
               and no securities  administrator  or the Federal  government  has
               recommended  or endorsed  the offering of the  Securities  or the
               shares issuable upon exercise of the Warrants.

          the  Warrant  Price paid.  In the event of any  exercise of the rights


                                    -- 14 --

          represented by this Warrant,  certificates  for the shares of stock so
          purchased  shall be delivered to the holder hereof as soon as possible
          and in any event  within ten (10) days of  receipt of such  notice and
          payment of the Warrant  Price and,  unless this Warrant has been fully
          exercised or expired,  a new Warrant  representing  the portion of the
          Shares, if any, with respect to which this Warrant shall not then have
          been  exercised  shall also be issued to the holder  hereof as soon as
          possible and in any event within such ten-day period.

     3.   Stock Fully Paid; Reservation of Shares. All shares that may be issued
          upon the exercise of the rights  represented by this Warrant will upon
          issuance,  be fully paid and  nonassessable,  and free from all taxes,
          liens and charges with respect to the issue thereof. During the period
          within which the rights  represented  by the Warrant may be exercised,
          the Company  will at all times have  authorized  and  reserved for the
          purpose of issuance upon exercise of the purchase rights  evidenced by
          this Warrant, a sufficient number of shares of Class A Common Stock to
          provide for the exercise of the rights represented by this Warrant.

     4.   Adjustment of Warrant Price and Number of Shares.  The number and kind
          of securities  purchasable upon the exercise of the Warrant  Agreement
          and the Warrant Price shall be subject to adjustment from time to time
          upon the occurrence of certain events, as follows:

          4.1  Reclassification.  In case  of any  reclassification,  change  or
               conversion  of the  Company's  Class A Common Stock (other than a
               change in par value,  or from par value to no par value,  or from
               no par value to par  value,  or as a result of a  subdivision  or
               combination),  the Company, shall execute a new Warrant Agreement
               (in form and  substance  reasonably  satisfactory  to the Holder)
               providing  that the Holder of this Warrant  Agreement  shall have
               the right to exercise  such new Warrant  Agreement  and upon such
               exercise  and  payment of the then  applicable  Warrant  Price to
               receive, in lieu of each Share theretofore issuable upon exercise
               of this  Warrant  Agreement,  the kind and  amount  of  shares of
               stock, other securities,  money and property receivable upon such
               reclassification  or  change  by a holder of one share of Class A
               Common  Stock.  Such new  Warrant  Agreement  shall  provide  for
               adjustments  that  shall  be  as  nearly  equivalent  as  may  be
               practicable to the adjustments  provided for in this Section 4.1.
               The  provisions  of this  Section  4.1 shall  similarly  apply to
               successive reclassifications and changes.

          4.2  Subdivision or Combination of Shares.  If the Company at any time
               while  this  Warrant  remains  outstanding  and  unexpired  shall
               subdivide or combine its Class A Common Stock,  the Warrant Price
               and the number of Shares  issuable upon exercise  hereof shall be
               equitably adjusted.

          4.3  Stock Dividends. If the Company at any time while this Warrant is
               outstanding and unexpired shall pay a dividend  payable in shares
               of Class A Common  Stock  (except any  distribution  specifically
               provided for in the  foregoing  Sections  4.1 and 4.2),  then the
               Warrant  Price  shall be  adjusted,  from and  after  the date of
               determination  of shareholders  entitled to receive such dividend
               or  distribution,  to that price  determined by  multiplying  the


                                    -- 15 --

               Warrant  Price  in  effect  immediately  prior  to  such  date of
               determination  by a fraction (a) the  numerator of which shall be
               the total  number of shares of Class A Common  Stock  outstanding
               immediately  prior to such dividend or distribution,  and (b) the
               denominator of which shall be the total number of shares of Class
               A Common Stock  outstanding  immediately  after such  dividend or
               distribution  and the number of Shares  subject  to this  Warrant
               shall be appropriately adjusted.

          4.4  No Impairment.  The Company will not, by amendment of its Charter
               or through  any  reorganization,  recapitalization,  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 Company,  but will at all times in
               good faith assist in the carrying  out of all the  provisions  of
               this  Article 4 and in the  taking  of all such  action as may be
               necessary  or  appropriate  in order to protect the rights of the
               Holder of this Warrant Agreement against impairment.

          4.5  Notices of Record Date. In the event of any taking by the Company
               of a record of its  shareholders  for the purpose of  determining
               shareholders  who are entitled to receive payment of any dividend
               or  other  distribution,   or  for  the  purpose  of  determining
               shareholders  who are  entitled  to vote in  connection  with any
               proposed merger or  consolidation of the Company with or into any
               other  corporation,  or any proposed sale, lease or conveyance of
               all or  substantially  all of the assets of the  Company,  or any
               proposed  liquidation,  dissolution or winding up of the Company,
               the Company  shall mail to the holder of this  Warrant,  at least
               fifteen (15) days prior to the date specified  therein,  a notice
               specifying  the date on which any such  record is to be taken for
               the  purpose  of such  dividend,  distribution  or vote,  and the
               amount and character of such dividend, distribution or vote.

     5.   Notice of Adjustments.  Whenever the Warrant Price or number of Shares
          shall be adjusted pursuant to the provisions hereof, the Company shall
          within  thirty  (30) days of such  adjustments  deliver a  certificate
          signed by its chief  financial  officer  to the  registered  holder(s)
          hereof  setting forth in reasonable  detail,  the event  requiring the
          adjustment,  the  amount of the  adjustment,  the method by which such
          adjustment was  calculated,  and the Warrant Price after giving effect
          to such adjustment.

     6.   Fractional  Shares.  No fractional Shares will be issued in connection
          with any exercise hereunder, but in lieu of such fractional shares the
          Company  shall  make a cash  payment  therefore  upon the basis of the
          Warrant Price then in effect.

     7.   Compliance with Securities Act, Disposition of Shares.

          7.1  Compliance with  Securities  Act. The holder of this Warrant,  by
               acceptance  hereof,  reconfirms the  representations  made by the
               Purchaser in a subscription  agreement with the Company as of the
               date  hereof  (the  "Subscription  Agreement")  and agrees to the
               placement of a  restrictive  transfer  legend on this Warrant and
               the certificates representing the shares.

                                    -- 16 --

               7.2  Disposition  of  Warrants  and Shares.  With  respect to any
                    offer,  sale or other  disposition  of this  Warrant  or any
                    Shares  acquired  pursuant to the  exercise of this  Warrant
                    prior to  registration  of this Warrant or such Shares,  the
                    holder  hereof and each  subsequent  holder of this  Warrant
                    agrees to give written  notice to the Company prior thereto,
                    describing  briefly  the  manner  thereof,  together  with a
                    written  opinion of such  holder's  counsel,  if  reasonably
                    requested by the Company  (and,  in such case,  such counsel
                    and opinion must be  reasonably  acceptable to the Company),
                    to the effect that such offer,  sale or other disposition my
                    be effected without registration or qualification (under the
                    Securities  Act of 1933 (the "Act") as then in effect or any
                    federal or state law then in effect) and indicating  whether
                    or not under the Act  certificates  for this Warrant or such
                    Shares  to be sold or  otherwise  disposed  of  require  any
                    restrictive   legend  as  to  applicable   restrictions   on
                    transferability  in order to insure compliance with the Act.
                    Each  certificate  representing  this  Warrant or the Shares
                    thus  transferred  (except a transfer  pursuant to Rule 144)
                    shall  bear a legend as to the  applicable  restrictions  on
                    transferability  in order to ensure compliance with the Act,
                    unless in the  aforesaid  opinion of counsel for the holder,
                    such legend is not  required  in order to ensure  compliance
                    with  the  Act.   The  Company   may  issue  stop   transfer
                    instructions  to its transfer  agent in connection  with the
                    foregoing restrictions.

     8.   Rights as  Shareholders.  No holder of the Warrant,  as such, shall be
          entitled  to vote or  receive  dividends  or be deemed  the  holder of
          Shares or any other securities of the Company which may at any time be
          issuable on the exercise  thereof for any purpose,  nor shall anything
          contained  herein,  be  construed  to confer  upon the  holder of this
          Warrant,  as such any of the rights of a shareholder of the Company or
          any right to vote for the  election  of  directors  or upon any matter
          submitted to shareholders at any meeting thereof, or to receive notice
          of  meetings  (except as  otherwise  provided  in Section  4.5 of this
          warrant),  or to receive dividends or subscription rights or otherwise
          until  this  Warrant   shall  have  been   exercised  and  the  Shares
          purchasable upon the exercise hereof shall have become deliverable, as
          provided herein.

     9.   Representations  and Warranties.  This Warrant is issued and delivered
          on the basis of the following:

          9.1  Authorization and Delivery. This Warrant has been duly authorized

               paid and nonassessable.



                                    -- 17 --

     10.  Modification and Waiver.  This Warrant and any provision hereof may be
          changed,  waived,  discharged or  terminated  only by an instrument in
          writing  signed by the party against which  enforcement of the same is
          sought.

     11.  Notices.  Any notice,  request or other document required or permitted

          delivered in the manner set forth in the Subscription Agreement.

     12.  Binding Effect of  Successors.  This Warrant shall be binding upon any
          corporation succeeding the Company by merger of consolidation, and all
          of the obligations of the Company relating to the Shares issuable upon
          the exercise of this Warrant shall be as set forth in the Subscription
          Agreement,  the Company's  Charter and the Company's  by-laws (each as
          amended  from  time to  time)  and  shall  survive  the  exercise  and
          termination  of this Warrant and all of the covenants  and  agreements
          herein and in such other  documents  and  instruments  of the  Company
          shall inure to the benefit of the successors and assigns of the holder

          Company's expense, acknowledge in writing its continuing obligation to
          the  holder  hereof  in  respect  of  any  rights  (including  without
          limitation,  any right to  registration  of the  Shares)  to which the
          holder  hereof shall  continue to be entitled  after such  exercise in
          accordance with this Warrant;  provided that the failure of the holder
          hereof  to make any such  request  shall  not  affect  the  continuing
          obligation  of the  Company  to the  holder  hereof in respect of such
          rights.

     13.  Lost  Warrants or Stock  Certificates.  The Company  covenants  to the
          holder hereof that upon receipt of evidence reasonable satisfactory to
          the Company of the loss,  theft,  destruction,  or  mutilation of this
          Warrant or any stock  certificates  and, in the case of any such loss,
          theft  or  destruction,   upon  receipt  of  an  indemnity  reasonable
          satisfactory  to the  Company,  or in the case of any such  mutilation
          upon surrender and cancellation of such Warrant or stock  certificate,
          the Company will make and deliver a new Warrant or stock  certificate,
          or like tenor,  in lieu of the lost,  stolen,  destroyed  or mutilated
