<PAGE>

      1.1 This Warrant may be exercised in whole at any time commencing 9:00
      a.m., New York City time, on any business day on or after the issuance
      thereof and continuing up to the third anniversary thereof (the "Warrant
      Period"), by the surrender of this Warrant (with a duly executed exercise
      form in the form attached at the end hereof as Exhibit A) at the principal
      office of the Company, together with the proper payment of the Per Share
      Warrant Price times the number of Warrant Shares.

certificate or certificates in the name of Holder for the Warrant Shares to
which the Holder shall be entitled and (b) deliver the other securities and
properties receivable upon the exercise of this Warrant, pursuant to the
provisions of this Warrant.

      1.3 Any stamp tax attributable to the issuance of the Shares shall be
      borne solely by Holder.

      1.4 Unless there is an effective registration statement under the
      Securities Act of 1933, as amended, (the "Securities Act") covering the
      resale of the Warrant Shares, at the option of the Holder, in lieu of
      exercising this Warrant in the manner provided in Subsection 1.1 above,
      the Holder may elect, pursuant to the terms of this Subsection 1.1, to
      receive Shares equal to the value of this Warrant (taking into account
      only that portion of this Warrant that is then exercisable) by surrender
      of this Warrant at the principal office of the Company together with
      notice of such election in which event the Company shall issue to the
      Holder a number of Shares using the following formula:

                                  X = Y(A-B)
                                      ------
                                         A

where X = The number of Shares to be issued to the Holder.

      Y = The number of Shares purchasable under this Warrant (at the date of
such calculation).

      A = The fair market value of one Share (at the date of such calculation).

      B = The Per Share Warrant Purchase Price.

2. Representations and Warranties

      The Holder (i) represents, warrants, covenants and agrees that the Warrant
      and the underlying Warrant Shares are being acquired by the Holder for the
      Holder's own account, for investment purposes only, and not with a view to
      or for the sale in connection with any distribution thereof or with any
      present intention of selling or distributing all or any part of the
      Warrant or the Warrant Shares; (ii) understands (x) that


                                       6
<PAGE>

      if it should thereafter decide to dispose of such Warrant or Warrant
      Shares (which it does not contemplate at such time) it may do so only in
      compliance with the Securities Act, (y) this Warrant and the Warrant
      Shares are not registered under the Securities Act; and (iii) acknowledges
      that, as of the date hereof, it has been given a full opportunity to ask
      questions of and to receive answers from the Company concerning this
      Warrant and the Warrant Shares and the business of the Company and to
      obtain such information as it desired in order to evaluate the acquisition
      of this Warrant and the Warrant Shares, and all questions have been
      answered to its full satisfaction.

3. Reservation of Shares

      The Company covenants that at all times during the Warrant Period it shall
      have authorized and in reserve, and will keep available solely for
      issuance or delivery upon exercise of the Warrant, the Warrant Shares and
      other securities and properties as from time to time shall be receivable
      upon the exercise of this Warrant, free and clear of preemptive rights and
      restrictions on sale or transfer except as otherwise set forth herein or
      in the By-Laws.

4. Registration Rights

      The Holder acknowledges that there exists an effective Company
      registration statement filed under the Securities Act on or about October
      4, 1999 [Registration No. 333-85085] (the "Filed Registration Statement"),
      which Filed Registration Statement inludes certain securities (other than
      the Warrant Shares) held by the Holder. The Holder further acknowledges
      that the Filed Registration Statement was filed pursuant to the terms of a
      Registration Rights Agreement, dated as May 13, 1999, between the Company
      and the Initial Investors named therein (the "Initial Investors"). The
      Company will explore the option of amending the Filed Registration
      Statement to include the Warrant Shares, subject to the Holder executing a
      lock-up agreement in substantailly the same form as previously signed by
      Biscount.

      In the event that the Company does not for whatever reason amend the Filed
      Registation Statement to include the Warrant Shares, then if the Company
      shall file a registration statement for any shares of its Common Stock, it
      shall include in the registration statement relating thereto the Warrant
      Shares, except that where such registration statement was filed on behalf
      of a shareholder or a rights holder, such inclusion shall be with the
      consent of such shareholder or rightsholder. In the event that such
      registration offering involves an underwriting, the rights of the Holder
      to have the Warrant Shares included in such registration statement shall
      be conditional upon the underwriter's determination as to the marketing
      factors requiring limitation of such right, and the underwriter may
      preclude any or all securities of the Holder which could have otherwise
      been included in such offering.


                                       7
<PAGE>

5. Adjustment

      5.1 In case prior to the expiration of this Warrant by exercise or by its
      terms the Company shall issue any shares of its Common Stock as a stock
      dividend or subdivide the number of outstanding shares of Common Stock
      into a greater number of shares by a stock split or a similar transaction,
      then, in either of such cases, the Exercise Price per share of the Warrant
      Shares purchasable pursuant to this Warrant in effect at the time of such
      action shall be proportionately reduced and the number of Warrant Shares
      purchasable at that time shall be proportionately increased; and,
      conversely, in the event the Company shall contract the number of
      outstanding shares of Common Stock by combining such shares into a smaller
      number of shares by a reverse split or similar transaction, then, in such
      case, the Exercise Price per share of the Warrant Shares purchasable
      pursuant to this Warrant shall be proportionately increased and the number
      of Warrant Shares purchaseable at that time shall be propotionately
      reduced. Any dividend paid or distributed upon the Common Stock in stock
      of any other class of securities convertible into shares of Common Stock
      shall be treated as a dividend paid in Common Stock to the extent that
      shares of Common Stock are issuable upon conversion thereof.

      5.2 In case of any consolidation or merger of the Company with or into
      another corporation (other than a merger or consolidation in which the
      Company is the surviving or the continuing corporation) or in the case of
      any sale or conveyance to another corporation or other entity of the
      property, assets or business of the Company as an entirety or
      substantially as an entirety, in any such case, the Company or such
      successor or purchasing corporation or entity, as the case may be, shall
      (i) execute with the Holder an agreement that the Holder shall have the
      right thereafter to receive upon the exercise of the Warrant the kind and
      amount of shares and/or other securities or other property which he would
      have owned or have been entitled to receive after the happening of such
      consolidation, merger, sale or conveyance had the Warrant been exercised
      immediately prior to such action, (ii) make effective provision in its
      certificate of its incorporation or otherwise, if necessary, in order to
      effect such agreement, and (iii) set aside or reserve for the benefit of
      the Holder, the stock, securities, property and cash to which the Holder
      would be entitled to upon exercise of this Warrant.

      5.3 In case of any reclassification or change of the Warrant Shares
      issuable upon exercise of this Warrant (other than a change in par value
      or from no par value to a specific par value, or as a result of a
      subdivision or combination, including any change in the shares into two or
      more classes or series of shares), or in the case of any consolidation or
      merger of another corporation into the Company in which the Company is the
      continuing corporation and in which there is a reclassification or change
      (including a change in the right to receive cash or other property) of the
      Shares (other than a change in the par value, or from no par


                                       8
<PAGE>

      value to a specific par value or, as a result of a subdivision or
      combination, including any change in the shares into two or more classes
      or series of shares), Holder shall have the right thereafter to receive
      upon exercise of this Warrant solely the kind and amount of shares of
      stock and other securities, property, cash or combination thereof
      receivable upon such reclassification, change, consolidation or merger by
      a holder of the number of Shares for which this Warrant might have been
      exercised immediately prior to such reclassification, change,
      consolidation or merger.

      5.4 The above provisions of this paragraph 5 shall similarly apply to
      successive reclassifications and changes of Shares and to successive
      consolidations, sales, leases or conveyances.

6. Limited Transfer

      (a) This Warrant may not be sold, transferred, assigned or hypothecated by
the Holder except in a transation exempt from registration under the Securities

purpose. The Company may treat the registered holder of record as the Holder for

as to such exemption. The Company shall permit any holder of a Warrant or his
duly authorized attorney, upon written request during ordinary business hours,
