1.    Exercise of Warrant.

      a) Exercise for Cash

      This Warrant may be exercised, in whole at any time or in part from time
      to time, commencing on the date hereof and prior to 5:00 P.M., New York
      City time, on the fifth anniversary of the date hereof, by the Holder by
      the surrender of this Warrant (with the
<PAGE>

      subscription form at the end hereof duly executed) at the address of the
      Escrow Agent set forth in Subsection 9(a) hereof, together with proper
      payment of the Aggregate Warrant Price, or the proportionate part thereof
      if this Warrant is exercised in part. Payment for GCA Warrants Shares
      shall be made by FedWire, certified or official bank check payable to the
      order of the Company and delivered to the Escrow Agent. If this Warrant is
      exercised in part, this Warrant must be exercised for a number of whole
      shares of the Common Stock, and the Holder is entitled to receive a new
      Warrant covering the GCA Warrants Shares which have not been exercised and
      setting forth the proportionate part of the Aggregate Warrant Price
      applicable to such GCA Warrants Shares. Upon such surrender of this
      Warrant the Company will (a) issue a certificate or certificates in the
      name of the Holder for the largest number of whole shares of the Common
      Stock to which the Holder shall be entitled and, if this Warrant is
      exercised in whole, in lieu of any fractional share of the Common Stock to
      which the Holder shall be entitled, pay to the Holder cash in an amount
      equal to the fair value of such fractional share (determined in such
      reasonable manner as the Board of Directors of the Company shall
      determine), and (b) deliver the other securities and properties receivable
      upon the exercise of this Warrant, or the proportionate part thereof if
      this Warrant is exercised in part. pursuant to the provisions of this
      Warrant.

      b) Cashless Exercise

      In lieu of exercising this Warrant in the manner set forth in paragraph
      1(a) above, the Warrant may be fully or partially exercised by surrender
      of the Warrant to the Escrow Agent without payment of any other
      consideration, commission or remuneration, by execution of the cashless
      exercise subscription form (at the end hereof, duly executed). The number
      of shares to be issued in exchange for the Warrant will be computed by
      subtracting the Warrant Exercise Price from the closing bid price of the
      common stock on the date of receipt of the cashless exercise subscription
      form, multiplying that amount by the number of shares being exercised
      pursuant to the Warrant, and dividing by the closing bid price as of the
      same date.

2.    Reservation of GCA Warrants Shares.

      The Company agrees that, prior to the expiration of this Warrant, the
      Company will at all times have authorized and in reserve, or held in
      escrow, and will keep available, solely for issuance or delivery upon the
      exercise of this Warrant, the shares of the Common Stock and other
      securities and properties as from time to time shall be receivable upon
      the exercise of this Warrant, free and clear of all restrictions on sale
      or transfer (except for applicable state or federal securities law
      restrictions) and free and clear of all pre-emptive rights.

3.    Protection Against Dilution.

      a)    If, at any time or from time to time after the date of this Warrant,
            the Company shall issue or distribute (for no consideration) to the
            holders of shares of Common Stock evidences of its indebtedness, any
            other securities of the Company or any cash,


                                        2
<PAGE>

            property or other assets (excluding a subdivision, combination or
            reclassification, or dividend or distribution payable in shares of
            Common Stock, referred to in Subsections 3(b) and 3(c), and also
            excluding cash dividends or cash distributions paid out of net
            profits legally available therefor if the full amount thereof,
            together with the value of other dividends and distributions made
            substantially concurrently therewith or pursuant to a plan which
            includes payment thereof, is equivalent to not more than 5% of the
            Company's net worth) (any such nonexcluded event being herein called
            a "Special Dividend"), the Per Share Warrant Price shall be adjusted
            by multiplying the Per Share Warrant Price then in effect by a
            fraction, the numerator of which shall be the then current market
            price of the Common Stock (defined as the average for the twenty
            consecutive trading days immediately prior to the record date of the
            daily closing bid price of the Common Stock as reported by the
            NASDAQ level III less the fair market value (as determined
            reasonably determined in good faith by the Company's Board of
            Directors) of the evidences of indebtedness, securities or property,
            or other assets issued or distributed in such Special Dividend
            applicable to one share of Common Stock and the denominator of which
            shall be such then current market price per share of Common Stock.
            An adjustment made pursuant to this Subsection 3(a) shall become
            effective immediately after the record date of any such Special
            Dividend.

      b)    In case the Company shall hereafter (i) pay a dividend or make a
            distribution on its capital stock in shares of Common Stock, (ii)
            subdivide its outstanding shares of Common Stock into a greater
            number of shares, or (iii) issue by reclassification of its Common
            Stock any shares of capital stock of the Company, the Per Share
            Warrant Price shall be adjusted so that the Holder of any Warrant
            upon the exercise hereof shall be entitled to receive the number of
            shares of Common Stock or other capital stock of the Company which
            he would have owned immediately prior thereto. An adjustment made
            pursuant to this Subsection 3(b) shall become effective immediately
            after the record date in the case of a dividend or distribution and
            shall become effective immediately after the effective date in the
            case of a subdivision, combination or reclassification. If, as a
            result of an adjustment made pursuant to this Subsection 3(b), the
            Holder of any Warrant thereafter surrendered for exercise shall
            become entitled to receive shares of two or more classes of capital
            stock or shares of Common Stock and other capital stock of the
            Company, the Board of Directors (whose determination shall be
            conclusive and shall be described in a written notice to the Holder
            of any Warrant promptly after such adjustment) shall determine the
            allocation of the adjusted Per Share Warrant Price between or among
            shares of such classes or capital stock or shares of Common Stock
            and other capital stock.

      c)    In case the Company shall hereafter combine its shares of Common
            Stock into a lesser number of shares (Reverse Split) the number of
            Warrants shall be proportionately adjusted. The Per Share Warrant
            Price shall be adjusted to the lower of (i) the average closing bid
            price of the Company's Common Stock as quoted by


                                        3
<PAGE>

            NASDAQ level III for the five-day trading period (Average Price)
            ending on the twentieth (20th) day subsequent to the effective date
            of such Reverse Split, or (ii) the proportionate per share price
            based on the Reverse Split, i.e. $1.25 per share in the event of a
            two for one split.

      d)    Except as provided in Subsection 3(f), in case the Company shall
            hereafter issue or sell any shares of Common Stock for a
            consideration per share less than the Per Share Warrant Price on the
            date of such issuance or sale, the Per Share Warrant Price shall be
            adjusted as of the date of such issuance or sale so that the same
            shall equal the consideration per share received by the Company upon
            such issuance or sale; provided, however, that no adjustment of the
            Per Share Warrant Price shall be required in connection with the
            issuance of shares upon the exercise of presently outstanding
            warrants or options.

      e)    Except as provided in Subsection 3(a) and 3(f), in case the Company
            shall hereafter issue or sell any rights, options, warrants or
            securities convertible into Common Stock entitling the holders
            thereof to purchase Common Stock or to convert such securities into
            Common Stock at a price per share (determined by dividing (i) the
            total amount, if any, received or receivable by the Company in
            consideration of the issuance or sale of such rights, options,
            warrants or convertible securities plus the total consideration, if
            any, payable to the Company upon exercise or conversion thereof
            (Total Consideration) by (ii) the number of additional shares of
            common stock issuable upon exercise or conversion of such
            securities) less than the then current Per Share Warrant Price in
            effect on the date of such issuance or sale, the Per Share Warrant
            Price shall be adjusted as of the date of such issuance or sale so
            that the same shall equal the price determined by dividing (i) the
            sum of (a) the number of shares of Common Stock outstanding on the
            date of such issuance or sale multiplied by the Per Share Warrant
            Price plus (b) the Total Consideration by (ii) the number of shares
            of Common Stock outstanding on the date of such issuance or sale
            plus (iii) the maximum number of additional shares of Common Stock
            issuable upon exercise or conversion of such securities.

      f)    In case of any capital reorganization or reclassification, or any
            consolidation or merger to which the Company is a party other than a
            merger or consolidation in which the Company is the continuing
            corporation, or in case of any sale or conveyance to another entity
            of the property of the Company as an entirety or substantially as
            an entirety, or in the case of any statutory exchange of securities
            with another corporation (including any exchange effected in
            connection with a merger of a third corporation into the
            Company), the Holder of this Warrant shall have the right
            thereafter to convert such Warrant into the kind and amount of
            securities, cash or other property which he would have owned or have
            been entitled to receive immediately after such reorganization,
            reclassification, consolidation, merger, statutory exchange, sale or
            conveyance had this Warrant been converted


                                        4
<PAGE>

            immediately prior to the effective date of such reorganization,
            reclassification, consolidation, merger, statutory exchange, sale or
            conveyance and in any such case, if necessary, appropriate
            adjustment shall be made in the application of the provisions set
            forth in this Section 3 with respect to the rights and interests
            thereafter of the Holder of this Warrant to the end that the
            provisions set forth in this Section 3 shall thereafter
            correspondingly be made applicable, as nearly as may reasonably be,
            in relation to any shares of stock or other securities or be. in
            relation to any shares of stock or other securities or property
            thereafter deliverable on the conversion of this Warrant. The above
            provisions of this Subsection 3(f) shall similarly apply to
            successive reorganizations, reclassifications, consolidations,
            mergers, statutory exchanges, sales or conveyances. The issuer of
            any shares of stock or other securities or property thereafter
            deliverable on the conversion of this Warrant shall be responsible
            for all of the agreements and obligations of the Company hereunder.
            Notice of any such reorganization, reclassification, consolidation,
            merger, statutory exchange, sale or conveyance and of said
            provisions so proposed to be made, shall be mailed to the Holders of
            the Warrants not less than 20 business days prior to such event. A
            sale of all or substantially all of the assets of the Company for a
            consideration consisting primarily of securities shall be deemed a
            consolidation or merger for the foregoing purposes.

      g)    No adjustment in the Per Share Warrant Price shall be required
            unless such adjustment would require an increase or decrease of at
            least $0.01 per share of Common Stock; provided, however, that any
            adjustments which by reason of this Subsection 3(g) are not required
            to be made shall be carried forward and taken into account in any
            subsequent adjustment; provided further, however, that adjustments
            shall be required and made in accordance with the provisions of this
            Section 3 (other than this Subsection 3(g) not later than such time
            as may be required in order to preserve the tax-free nature of a
            distribution to the Holder of this Warrant or Common Stock issuable
            upon exercise hereof All calculations under this Section 3 shall be
            made to the nearest cent. Anything in this Section 3 to the contrary
            notwithstanding, the Company shall be entitled to make such
            reductions in the Per Share Warrant Price, in addition to those
            required by this Section 3, as it in its discretion shall deem to be
            advisable in order that any stock dividend, subdivision of shares or
            distribution of rights to purchase stock or securities convertible
            or exchangeable for stock hereafter made by the Company to its
            shareholders shall not be taxable.

      h)    Whenever the Per Share Warrant Price is adjusted as provided in this
            Section 3 and upon any modification of the rights of a Holder of
            Warrants in accordance with this Section 3, the Company shall
            promptly obtain, at its expense, a certificate of a firm of
            independent public accountants of recognized standing selected by
            the Board of Directors (who may be the regular auditors of the
            Company) setting forth the Per Share Warrant Price and the number
            of GCA Warrants Shares after such adjustment or the effect of such
            modification, a brief statement of the facts requiring such


                                        5
<PAGE>

            adjustment or modification and the manner of computing the same and
            cause copies of such certificate to be mailed to the Holders of the
            Warrants.

      i)    If the Board of Directors of the Company shall declare any dividend
            or other distribution with respect to the Common Stock, other than a
            cash distribution out of earned surplus, the Company shall mail
            notice thereof to the Holders of the Warrants not less than 10
            business days prior to the record date fixed for determining
            shareholders entitled to participate in such dividend or other
            distribution.

      The Company agrees that the shares of the Common Stock represented by each
      and every certificate for GCA Warrants Shares delivered on the exercise of
      this Warrant shall, at the time of such delivery, be validly issued and
      outstanding, fully paid and nonassessable, and not subject to pre-emptive
      rights, and the Company will take all such actions as may be necessary to
      assure that the par value or stated value, if any, per share of the Common
      Stock is at all times equal to or less than the then Per Share Warrant
      Price. The Company further covenants and agrees that it will pay, when due
      and payable, any and all Federal and state stamp, original issue or
      similar taxes which may be payable in respect of the issue of any Warrant
      Share or certificate therefor.

            with the terms of the Financing Agreement.

            request and (iii) take such other actions as may be reasonably
            necessary or advisable to enable such Holders and such Underwriters
            to consummate the sale or distribution in such jurisdiction or
            jurisdictions in which such Holders shall havc reasonably
            requested that the GCA Warrants Shares be sold.

            offering of Common Stock pursuant to the Underwriting Agreement and
            such Holders will indemnify the Company (and the Underwriters, if
            applicable) with respect to information furnished by them in writing

            extent as the Underwriters have indemnified the Company.

6.    Limitation on Exercise.

      No Holder(s) of GCA Warrants shall be permitted to exercise any GCA
Warrants to the extent that such exercise would cause any Holder to be the
beneficial owner of more than 5% of the then outstanding WWDI Common Stock, at

acquiring more than an aggregate of 5% of the Common Stock, so long as such
Holder does not beneficially own more than 5% of WWDI Common Stock, at any given
time.
