          ---------------------------
          Certificate by executing the Form of Election attached hereto as
          Exhibit A and delivering it to the Company and tendering the requisite
          aggregate Exercise Price for the number of shares of Series A

          hereinafter referred to as the "Exercise Date") provided, that in lieu

          Holder may elect to exercise this Warrant Certificate on a net basis
          whereupon the Company will issue shares of Series A Preferred Stock in
          accordance with the following formula:

     Where:  A=  the number of shares of Series A Preferred Stock to be issued
to the Holder.
             B=   the number of shares of Series A Preferred Stock requested to
                  be exercised under this Warrant Certificate.

                                      -3-
<PAGE>

             C=  the fair market value of one share of Series A Preferred Stock.
             D=  the Exercise Price.

     For purposes of the above calculation, current fair market value of the
Series A Preferred Stock shall be determined as follows:

           (i) if the Common Stock is then admitted to trading on a national
     securities   exchange or traded in the NASDAQ National Market System,
     current fair market value of a share of the Series A Preferred Stock shall
     be the product of (x) the average of the closing prices of the Common Stock
     over the 20-day period ending on the date the current fair market value of
     the securities is being determined or, if there have been no sales on any
     such exchange or any such quotation on any day, the average of the highest
     bid and lowest asked prices on all such exchanges or such system at the end
     of such day, or, if any day the Common Stock is not so listed, the average
     of the representative bid and asked prices quoted in the NASDAQ system as
     of 4:00 p.m., Boston time, or, if on any day that Common Stock is not
     quoted in the NASDAQ system, the average of the highest bid and lowest
     asked price on such day in the domestic over-the-counter market as reported
     by the National Quotation Bureau, Incorporated, or any similar successor
     organization and (y) the number of shares of Common Stock into which each
     share of Series A Preferred Stock is convertible at the time of such
     exercise; or

           (ii) If at any time the Common Stock is not listed on any securities
     exchange or quoted in the NASDAQ system or the over-the-counter market, the
     current fair market value of the Series A Preferred Stock shall be the
     product of (x) the highest price per share which the Company could obtain
     from a willing buyer (not a current employee or director) for shares of
     Common Stock sold by the Company, from authorized but unissued shares, as
     determined in good faith by the Board of Directors of the Company and (y)
     the number of shares of Common Stock into which each share of Series A
     Preferred Stock is convertible at the time of each exercise.

           Upon partial exercise of the Warrant, the Company shall promptly
     issue an   amended Warrant Certificate representing the remaining number of
     shares purchasable hereunder.  All other terms and conditions of such
     amended Warrant Agreement shall be identical to those contained herein.

     (e)  Issuance of Shares of Series A Preferred Stock.  As soon as
          ----------------------------------------------
          practicable after the Exercise Date the Company shall (provided that
          it has received the Form of Election duly executed, accompanied by
          payment of the Exercise Price pursuant to Section 2(b) hereof for each
          of the shares of Common Stock to be purchased) promptly cause
          certificates for the number of shares of Common Stock to be issued in
          respect of this Warrant Certificate to be delivered to or upon the
          order of the Holder, registered in such name as may be designated by
          such holder; provided that if the Common Stock is to be registered in
          the name of any entity or person other than the Holder, the Company
          may require evidence of compliance by the Holder with all applicable
          securities laws, including, without limitation, an opinion of Holder's
          counsel reasonably acceptable to the Company

                                      -4-
<PAGE>

          and the payment by the Holder of any necessary transfer taxes in
          connection with the issuance of such Common Stock.

3.   Reservation and Availability of Series A Preferred Stock; Adjustments
     ---------------------------------------------------------------------

     (a)  Reservation of Series A Preferred Stock.  The Company covenants and
          ---------------------------------------
          agrees that it will cause to be kept available out of its authorized
          and unissued Series A Preferred Stock, or its authorized and issued
          Series A Preferred Stock held in its treasury, the number of shares of
          Series A Preferred Stock that will be sufficient to permit the
          exercise in full of this Warrant Certificate.

     (b)  Series A Preferred Stock to be Duly Authorized and Issued, Fully Paid
          ---------------------------------------------------------------------
          and Non-Assessable.  The Company covenants and agrees that it will
          ------------------
          take all such action as may be necessary to ensure that all shares of
          Series A Preferred Stock delivered upon exercise of the Warrant and
          payment of the requisite aggregate Exercise Price thereof shall, at
          the time of delivery of the certificates for such shares, be duly and
          validly authorized and issued and fully paid and non-assessable
          shares.

     (c)  Series A Record Date.  Each person or entity in whose name any
          --------------------
          certificate for shares of Series A Preferred Stock is issued upon the
          exercise of this Warrant Certificate in accordance with its terms
          shall for all purposes be deemed to have become the holder of record
          of the shares of Series A Preferred Stock represented thereby on, and
          such certificate shall be dated, the date upon which the Form of
          Election was received by the Company and payment of the aggregate
          Exercise Price was received by the Company pursuant to Section 2(b)
          hereof.  Prior to the exercise of this Warrant Certificate, the Holder
          shall not be entitled to any rights of a stockholder of the Company
          with respect to the shares of Series A Preferred Stock for which this
          Warrant Certificate shall be exercisable, including, without
          limitation, the right to vote, to receive dividends or other
          distributions or to exercise any preemptive rights and shall not be
          entitled to receive any notice of any proceedings of the Company,
          except as provided herein.

     (d)  Adjustments to Exercise Price.  The Exercise Price for this Warrant
          ---------------------
          Certificate in effect from time to time shall be subject to adjustment
          as follows:

               (1)  Adjustment for Series A Preferred Stock Dividends,
                    --------------------------------------------------
                    Subdivisions and Combinations.  Upon the issuance of
                    -----------------------------
                    additional shares of Series A Preferred Stock as a dividend
                    or other distribution on outstanding Series A Preferred
                    Stock, the subdivision of outstanding shares of Series A
                    Preferred Stock into a greater number of shares of Series A
                    Preferred Stock, or the combination of outstanding shares of
                    Series A Preferred Stock into a smaller number of shares of
                    the Series A Preferred Stock, the Exercise Price shall,
                    simultaneously with the happening of such dividend,

                                      -5-
<PAGE>

                    distribution, subdivision or combination, be adjusted by
                    multiplying the then effective Exercise Price by a fraction,
                    the numerator of which shall be the number of shares of
                    Series A Preferred Stock outstanding immediately prior to
                    such event and the denominator of which shall be the number
                    of shares of Series A Preferred Stock outstanding
                    immediately after such event.  An adjustment made pursuant
                    to this Section 3(d)(i) shall be given effect, upon payment
                    of such a dividend or distribution, as of the record date
                    for the determination of stockholders entitled to receive
                    such dividend or distribution (on a retroactive basis) and
                    in the case of a subdivision or combination shall become
                    effective immediately as of the effective date thereof.

               (2)  Adjustment of Number of Shares.  Upon each adjustment to the
                    ------------------------------
                    Exercise Price pursuant to Section 3(d)(i) hereof, the
                    number of shares of Series A Preferred Stock purchasable
                    hereunder shall be adjusted, to the nearest whole share, to
                    the product obtained by multiplying the number of shares
                    purchasable immediately prior to such adjustment by a
                    fraction, the numerator of which shall be the Exercise Price
                    immediately prior to such adjustment and the denominator of
                    which shall be the Exercise Price immediately thereafter.

     (e)  Other Adjustments.  In the event the Company shall make or issue, or
          -----------------
          fix a record date for the determination of holders of Series A
          Preferred Stock entitled to receive, a dividend or other distribution
          payable in securities of the Company other than shares of Series A
          Preferred Stock, then and in each such event lawful and adequate
          provision shall be made so that the holders of Warrants shall receive
          upon exercise thereof in addition to the number of shares of Series A
          Preferred Stock receivable thereupon, the number of securities of the
          Company which such holders would have received had such Warrants been
          exercised on the date of such event and had such holders thereafter,
          during the period from the date of such event to and including the
          date of exercise, retained such securities receivable by such holders
          as aforesaid during such period, giving application to all adjustments
          called for during such period under this Section 3 as applied to such
          distributed securities.

     If the Series A Preferred Stock issuable upon the exercise of the Warrants
shall be changed into the same or different number of shares of any class or
classes of stock, whether by reclassification or otherwise (other than a
subdivision or combination of shares or stock dividend provided for above, or a
reorganization, merger, consolidation or sale of assets provided for elsewhere
in this Section 3), then and in each such event the holder of each Warrant shall
have the right thereafter to exercise such Warrant for the purchase of the kind
and amount of shares of stock and other securities and property receivable upon
such reorganization, reclassification or other change, by holders of the number
of shares of Series A Preferred Stock for which such

                                      -6-
<PAGE>

Warrants might have been exercised immediately prior to such reorganization,
reclassification or change, all subject to further adjustment as provided
herein.

     (f) Mergers and Other Reorganizations.  If at any time or from time to time
         ---------------------------------
there shall be a capital reorganization of the Series A Preferred Stock (other
than a subdivision, combination, reclassification or exchange of shares provided
for elsewhere in this Section 3) or a merger or consolidation of the Company
with or into another company, then, as a part of and as a condition to the
effectiveness of such reorganization, merger, consolidation, lawful and adequate
provision shall be made so that the Holder of this Warrant shall thereafter be
entitled to receive upon exercise the number of shares of stock or other
securities or property of the Company or of the successor Company resulting from
such merger or consolidation, to which a holder of Series A Preferred Stock
deliverable upon exercise would have been entitled on such capital
reorganization, merger or consolidation if this warrant had been exercised
immediately prior thereto.  In any such case, appropriate provisions (as
determined in good faith by the Company's Board of Directors) shall be made with
respect to the rights of the Holder of this Warrant after the reorganization,
merger or consolidation to the end that the provisions of this Section 3
(including without limitation provisions for adjustment of the Exercise Price
and the number of shares purchasable upon exercise) shall thereafter be
applicable, as nearly as may be, with respect to any shares of stock, securities
or assets to be deliverable thereafter upon the exercise.

     (g) Right to Purchase Additional Stock.  If the Company has not paid any
         ----------------------------------
Subordinated Promissory Note(s) entered into pursuant to the Subordinated Loan
Agreement in its entirety within thirty (30) days after the Maturity Date (as
defined in the applicable Subordinated Promissory Note(s)), then for each
additional month, or portion thereof, thereafter that the outstanding principal
is not paid, Holder shall have the right to purchase from the Company, at the
Exercise Price (adjusted as set forth herein), an additional number of shares of
Series A Preferred Stock, which number shall be determined by (i) multiplying
the outstanding principal amount which is due but unpaid on the applicable
Subordinated Promissory Note by 1% and (ii) dividing the product thereof by the
Exercise Price.

     (h) Antidilution Rights.  Additional antidilution rights applicable to the
         -------------------
Series A Preferred Stock purchasable hereunder are as set forth in the Company's
Certificate of Incorporation, as amended from time to time, a current true and
correct copy of which is attached hereto as Exhibit B.  The Company shall
promptly provide the Holder with any restatement, amendment, modification or
waiver of the Certificate of Incorporation.  The Company shall provide Holder
with prior written notice of any issuance of its stock or other equity security
(other than equity securities issued pursuant to an employee stock option or
similar plan) to occur after the date hereof, which notice shall include (a) the
price at which such stock or security is to be sold, (b) the number of shares to
be issued, and (c) such other information as may be reasonably requested and is
necessary to determine if a dilutive event has occurred.

          issuable upon conversion of such shares of Series A Preferred Stock
          have not been registered under the Securities Act or any applicable
          state securities ("blue sky") laws, by reason of specified exemptions
          from the registration provisions of the Securities Act and such laws.
          The Holder acknowledges that the Warrant, the shares of Series A
          Preferred Stock issuable upon exercise thereof and the shares of
          common stock of the Company issuable upon conversion of such shares of
          Series A Preferred Stock must be held indefinitely unless they are
          subsequently registered under the Securities Act or an exemption from
          such registration is available.  The Holder has been advised or is
          aware of the provisions of Rule 144 promulgated under the Securities
          Act, which permits the resale of shares purchased in a private
          placement subject to the satisfaction of certain conditions and that
          such Rule may not be available for resale of the shares of Series A
          Preferred Stock issuable upon exercise of the Warrant or the shares of
          Common Stock issuable upon conversion of such shares of Series A
          Preferred Stock.  The Holder has had an opportunity to discuss the
          Company's business, management and financial affairs with its
          management and has had the opportunity to review the Company's
          facilities.  The Holder is an "accredited investor" within the meaning
          of Regulation D promulgated under the Securities Act.  The Holder has
          its principal place of business in State of Illinois.

     (g)  Restrictions on Transferability.  None of the Warrant, the shares of
          -------------------------------
          Series A Preferred Stock received upon exercise thereof or the shares
          of Common Stock received upon conversion of such shares of Series A
          Preferred Stock shall be transferable, except to an affiliate of the
          Holder or to another financial institution (other than a competitor of
          the Company) upon the conditions specified in and in accordance with
