Company may require, as a condition of allowing such exercise, transfer or
exchange, that the Holder or transferee of such Warrant or Underlying
Securities, as the case may be, furnish to the Company a satisfactory opinion of
counsel to the effect that such exercise, transfer or exchange may be made
without registration under the Securities Act, provided that the disposition
thereof shall at all times be within the control of such Holder or transferee,
as the case may be, and provided further that nothing contained in this section

pursuant to the Registration Rights Agreement. The first Holder of this Warrant,
by acceptance hereof, represents to the Company that it is acquiring the
Warrants for investment and not with a view to the distribution thereof.

         3.   Exercise of Warrant.
              -------------------

              3.1. Exercise in Full.  Subject to the provisions hereof, this
                   ----------------
Warrant may be exercised in full by the Holder hereof by surrender of this
Warrant, with the form of subscription at the end hereof duly executed by such
Holder, to the Company at its principal office accompanied by payment, in cash
or by certified or official bank check payable to the order of the Company, in
the amount obtained by multiplying the number of shares of Common Stock called
for on the face of this Warrant (without giving effect to any adjustment
therein) by the Purchase Price per share.

              3.2. Partial Exercise.  Subject to the provisions hereof, this
                   ----------------
Warrant may be exercised in part by surrender of this Warrant in the manner and
at the place provided in subsection 3.1 except that the amount payable by the
Holder upon any partial exercise shall be the amount obtained by multiplying (a)
the number of shares of Common Stock (without giving effect to any adjustment
therein) designated by the Holder in the subscription at the end hereof by (b)
the Purchase Price per share.  Upon any such partial exercise, the Company at
its expense will forthwith issue and deliver to or upon the order of the Holder
hereof a new Warrant or Warrants of like tenor, in the name of the Holder hereof
or as such Holder (upon payment by such Holder of any applicable transfer taxes)
may request, calling in the aggregate on the face or faces thereof for the
number of shares of Common Stock equal (without giving effect to any

                                      -3-


adjustment therein) to the number of such shares called for on the face of this
Warrant minus the number of such shares designated by the Holder in the
subscription at the end hereof.

              3.3. Exercise by Surrender of Warrant or Shares of Common Stock.
                   ----------------------------------------------------------
In addition to the method of payment set forth in sections 3.1 and 3.2 and in
lieu of any cash payment required thereunder, the Holder(s) of the Warrants
shall have the right at any time and from time to time to exercise the Warrants
in full or in part by surrendering shares of Common Stock, Series B Preferred
Stock, the Warrant Certificate or other securities issued by the Company in the
manner and at the place specified in section 3.1 as payment of the aggregate
Purchase Price per share for the Warrants to be exercised. The number of
Warrants or shares of Common Stock to be surrendered in payment of the aggregate
Purchase Price for the Warrants to be exercised shall be determined by
multiplying the number of Warrants to be exercised by the Purchase Price per
share, and then dividing the product thereof by an amount equal to the Market
Price (as defined below) . The number of shares of Series B Preferred Stock or
such other securities to be surrendered in payment of the aggregate Purchase
Price for the Warrants to be exercised shall be determined in accordance with
the preceding sentence as if the Series B Preferred Stock or other securities
had been converted into Common Stock immediately prior to exercise or, in the
case the Company has issued other securities which are not convertible into
Common Stock, at the Market Price thereof.

              3.4. Definition of Market Price.  As used herein, the phrase
                   --------------------------
"Market Price" at any date shall be deemed to be (i) if the principal trading
market for such securities is an exchange, the average of the last reported sale
prices for the last five previous trading days in which a sale was reported, as
officially reported on any consolidated tape, (ii) if the principal market for
such securities is the over-the-counter market, the average of the high bid
prices on such trading days as set forth by Nasdaq or, (iii) if the security is
not quoted on Nasdaq, the average of the high bid prices on such trading days as
set forth in the National Quotation Bureau sheet listing such securities for
such day.  Notwithstanding the foregoing, if there is no reported closing price
or high bid price, as the case may be, on any of the ten trading days preceding
the event requiring a determination of Market Price hereunder, then the Market
Price shall be determined in good faith by resolution of the Board of Directors
of the Company, based on the best information available to it.

              3.5. Company to Reaffirm Obligations.  The Company will, at the
                   -------------------------------
time of any exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing its continuing obligation to afford to such Holder any
rights (including, without limitation, any right to registration of the
Underlying Securities) to which such Holder shall continue to be entitled after
such exercise in accordance with the provisions of this Warrant, provided that
                                                                 --------
if the Holder of this Warrant shall fail to make any such request, such failure
shall not affect the continuing obligation of the Company to afford such Holder
any such rights.


         4.   Delivery of Stock Certificates, etc., on Exercise.  As soon as
              -------------------------------------------------
practicable after the exercise of this Warrant in full or in part, and in any
event within three business days thereafter, the Company at its own expense
(including the payment by it of any applicable issue taxes) will cause to be
issued in the name of and delivered to the Holder hereof, or as such

                                      -4-


Holder (upon payment by such Holder of any applicable transfer taxes) may
direct, a certificate or certificates for the number of full paid and non-
assessable shares of Common Stock or Other Securities to which such Holder shall
be entitled upon such exercise, plus, in lieu of any fractional share to which
such Holder would otherwise be entitled, cash equal to such fraction multiplied
by the then current Market Price of one full share, together with any other
stock or other securities and property (including cash, where applicable) to
which such Holder is entitled upon such exercise pursuant to section 5 or
otherwise.


         5.   Adjustment for Dividends in Other Stock, Property, etc.;
              --------------------------------------------------------
Reclassification, etc.  In case at any time or from time to time after the
- ----------------------
Original Issue Date the holders of Common Stock (or Other Securities) shall have
received, or (on or after the record date fixed for the determination of
stockholders eligible to receive) shall have become entitled to receive, without
payment therefor

              (a) other or additional stock or other securities or property
         (other than cash) by way of dividend, or

              (b) any cash paid or payable (including, without limitation, by
         way of dividend), or

              (c) other or additional (or less) stock or other securities or
         property (including cash) by way of spin-off, split-up,
         reclassification, recapitalization, combination of shares or similar
         corporate rearrangement,

then, and in each such case the Holder of this Warrant, upon the exercise hereof
as provided in section 3, shall be entitled to receive the amount of stock and
other securities and property (including cash in the cases referred to in
subdivisions (b) and (c) of this section 5) which such Holder would hold on the
date of such exercise if on the Original Issue Date such Holder had been the
Holder of record of the number of shares of Common Stock called for on the face
of this Warrant and had thereafter, during the period from the Original Issue
Date to and including the date of such exercise, retained such shares and all
such other or additional (or less) stock and other securities and property
(including cash in the cases referred to in subdivisions (b) and (c) of this
section 5) receivable by such Holder as aforesaid during such period, giving
effect to all adjustments called for during such period by sections 6 and 7
hereof.


         6.   Reorganization, Consolidation, Merger, etc.  In case the Company
              -------------------------------------------
after the Original Issue Date shall (a) effect a reorganization, (b) consolidate
with or merge into any other person, or (c) transfer all or substantially all of
its properties or assets to any other person under any plan or arrangement
contemplating the dissolution of the Company, then, in each such case, the
Holder of this Warrant, upon the exercise hereof as provided in section 3 at any
time after the consummation of such reorganization, consolidation or merger or
the effective date of such dissolution, as the case may be, shall be entitled to
receive (and the Company shall be entitled to deliver), in lieu of the
Underlying Securities issuable upon such exercise prior to such consummation or
such effective date, the stock and other securities and property (including
cash)

                                      -5-


to which such Holder would have been entitled upon such consummation or in
connection with such dissolution, as the case may be, if such Holder had so
exercised this Warrant immediately prior thereto, all subject to further
adjustment thereafter as provided in sections 5 and 7 hereof. The Company shall
not effect any such reorganization, consolidation, merger or sale, unless prior
to or simultaneously with the consummation thereof, the successor corporation
resulting from such consolidation or merger or the corporation purchasing such
assets or the appropriate corporation or entity shall assume, by written
instrument, the obligation to deliver to each Holder the shares of stock, cash,
other securities or assets to which, in accordance with the foregoing
provisions, each Holder may be entitled to and all other obligations of the
Company under this Warrant.

         7.   Other Adjustments.
              -----------------

              7.1. General.  In any case to which Sections 5 and 6 hereof are
                   -------
not applicable, where the Company shall issue or sell shares of its Common Stock
after the Original Issue Date for a consideration per share less than the
Purchase Price per share in effect pursuant to the terms of this Warrant at the
time of issuance or sale of such additional shares (the "Lower Price"), then the
Purchase Price in effect hereunder shall simultaneously with such issuance or
sale be reduced to an amount equal to the Lower Price.  In the event of an
adjustment to the Purchase Price under this Section 7, the number of shares of
Underlying Securities issuable upon exercise hereof shall be increased so that
the aggregate exercise price of this Warrant is not reduced as a result of such
reduction of Purchase Price.

              7.2. Convertible Securities.  (a)  In case the Company shall issue
                   ----------------------
or sell any securities convertible into Common Stock of the Company
("Convertible Securities") after the date hereof, there shall be determined the
price per share for which Common Stock is issuable upon the conversion or
exchange thereof, such determination to be made by dividing (i) the total amount
received or receivable by the Company as consideration for the issue or sale of
such Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the conversion or exchange
thereof, by (ii) the maximum number of shares of Common Stock of the Company
issuable upon the conversion or exchange of all of such Convertible Securities.

                   (b) If the price per share so determined shall be less than
the applicable Purchase Price per share, then such issue or sale shall be deemed
to be an issue or sale for cash (as of the date of issue or sale of such
Convertible Securities) of such maximum number of shares of Common Stock at the
price per share so determined, provided that, if such Convertible Securities
shall by their terms provide for an increase or increases or decrease or
decreases, with the passage of time, in the amount of additional consideration,
if any, to the Company, or in the rate of exchange, upon the conversion or
exchange thereof, the adjusted Purchase Price per share shall, forthwith upon
any such increase or decrease becoming effective, be readjusted to reflect the
same, and provided further, that upon the expiration of such rights of
conversion or exchange of such Convertible Securities, if any thereof shall not
have been exercised, the adjusted Purchase Price per share shall forthwith be
readjusted and thereafter be the price which it would have been had an
adjustment been made on the basis that the only shares of Common Stock so issued
or sold were issued or sold upon the conversion or exchange

                                      -6-


of such Convertible Securities, and that they were issued or sold for the
consideration actually received by the Company upon such conversion or exchange,
plus the consideration, if any, actually received by the Company for the issue
or sale of all of such Convertible Securities which shall have been converted or
exchanged.

          7.3. Rights and Options. (a) In case the Company shall grant any
               ------------------
rights or options to subscribe for, purchase or otherwise acquire Common Stock,
there shall be determined the price per share for which Common Stock is issuable
upon the exercise of such rights or options, such determination to be made by
dividing (i) the total amount, if any, received or receivable by the Company as
consideration for the granting of such rights or options, plus the minimum
aggregate amount of additional consideration payable to the Company upon the
exercise of such rights or options, by (ii) the maximum number of shares of
Common Stock of the Company issuable upon the exercise of such rights or
options.

               (b) If the price per share so determined shall be less than the
applicable Purchase Price per share, then the granting of such rights or options
shall be deemed to be an issue or sale for cash (as of the date of the granting
of such rights or options) of such maximum number of shares of Common Stock at
the price per share so determined, provided that, if such rights or options
shall by their terms provide for an increase or increases or decrease or
decreases, with the passage of time, in the amount of additional consideration
payable to the Company upon the exercise thereof, the adjusted Purchase Price
per share shall, forthwith upon any such increase or decrease becoming
effective, be readjusted to reflect the same, and provided, further, that upon
the expiration of such rights or options, if any thereof shall not have been
exercised, the adjusted Purchase Price per share shall forthwith be readjusted
and thereafter be the price which it would have been had an adjustment been made
on the basis that the only shares of Common Stock so issued or sold were those
issued or sold upon the exercise of such rights or options and that they were
issued or sold for the consideration actually received by the Company upon such
exercise, plus the consideration, if any, actually received by the Company for
the granting of all such rights or options, whether or not exercised.

          7.4. Combination of Shares. If the number of shares of Common Stock
               ---------------------
outstanding at any time after the date hereof is decreased by a combination or
reverse stock split of the outstanding shares of Common Stock of the Company,
the Purchase Price shall be increased and the number of shares of Common Stock
purchasable under this Warrant shall be decreased in proportion to such decrease
in outstanding shares of Common Stock.

          7.5. Exceptions. This Section 7 shall not apply to (a) the issuance of
               -----------
the Series B Preferred Stock, (b) the issuance of shares of Common Stock upon
conversion of the Series B Preferred Stock, (c) upon the exercise of the
Warrants aggregating not in excess of 2,100,000 shares, (d) issuances of Common
Stock, Convertible Securities, rights and options that have been approved by the
holders of not less than a majority of the outstanding shares of Series B
Preferred Stock, (e) issuances of Common Stock pursuant to the exercise of
options, warrants and rights outstanding on the date hereof or issued pursuant
to the Company's existing stock option plan or a plan which has been approved by
the holders of not less than a majority of the outstanding shares of Series B
Preferred Stock or (f) the issuance of warrants to a lender pursuant to a loan
to the Company with a term of at least four years and in an amount of not less
than

                                      -7-


$10,000,000 (and the issuance of shares of Common Stock on the exercise of such
lender warrants).

         8.   Further Assurances.  The Company will take all such action as may
              ------------------
be necessary or appropriate in order that the Company may validly and legally
issue fully paid and non-assessable shares of stock upon the exercise of all
Warrants from time to time outstanding.


         9.   Accountants' Certificate as to Adjustments.  In each case of any
              ------------------------------------------
adjustment or readjustment in the shares of Common Stock (or Other Securities)
issuable upon the exercise of the Warrants, the Company at its expense will
promptly cause the Company's regularly retained auditor to compute such
adjustment or readjustment in accordance with the terms of the Warrants and
prepare a certificate setting forth such adjustment or readjustment and showing
in detail the facts upon which such adjustment or readjustment is based, and the
number of shares of Common Stock outstanding or deemed to be outstanding.  The
Company will forthwith mail a copy of each such certificate to each Holder.


         10.  Notices of Record Date, etc.  In the event of
              ----------------------------

              (a) any taking by the Company of a record of the Holders of any
         class of securities for the purpose of determining the Holders thereof
         who are entitled to receive any dividend or other distribution, or any
         right to subscribe for, purchase or otherwise acquire any shares of
         stock of any class or any other securities or property, or to receive
         any other right, or

              (b) any capital reorganization of the Company, any
         reclassification or recapitalization of the capital stock of the
         Company or any transfer of all or substantially all the assets of the
         Company to or consolidation or merger of the Company with or into any
         other person, or

              (c) any voluntary or involuntary dissolution, liquidation or
         winding-up of the Company, or

              (d) any proposed issue or grant by the Company of any shares of
         stock of any class or any other securities, or any right or option to
         subscribe for, purchase or otherwise acquire any shares of stock of any
         class or any other securities (other than the issue of Common Stock on
         the exercise of the Warrants), then and in each such event the Company
         will mail or cause to be mailed to each Holder of a Warrant a notice
         specifying (i) the date on which any such record is to be taken for the
         purpose of such dividend, distribution or right, and stating the amount
         and character of such dividend, distribution or right, (ii) the date on
         which any such reorganization, reclassification, recapitalization,
         transfer, consolidation, merger, dissolution, liquidation or winding-up
         is to take place, and the time, if any, as of which the Holders of
         record of Underlying Securities shall be entitled to exchange their
         shares of Underlying Securities for securities or other property
         deliverable

                                      -8-


         upon such reorganization, reclassification, recapitalization, transfer,
         consolidation, merger, dissolution, liquidation or winding-up, and
         (iii) the amount and character of any stock or other securities, or
         rights or options with respect thereto, proposed to be issued or
         granted, the date of such proposed issue or grant and the persons or
         class of persons to whom such proposed issue or grant and the persons
         or class of persons to whom such proposed issue or grant is to be
         offered or made. Such notice shall be mailed at least 20 days prior to
         the date therein specified.

         11.  Reservation of Stock, etc., Issuable on Exercise of Warrants.  The
              ------------------------------------------------------------
Company will at all times reserve and keep available, solely for issuance and
delivery upon the exercise of the Warrants, all shares of Common Stock (or Other
Securities) from time to time issuable upon the exercise of the Warrants.


         12.  Listing on Securities Exchanges; Registration.  In furtherance and
              ---------------------------------------------

time shall list any Common Stock on any national securities exchange and shall
register such Common Stock under the Exchange Act, the Company will, at its
expense, simultaneously list on such exchange or Nasdaq, upon official notice of

shares of Common Stock from time to time issuable upon the exercise of the
Warrants; and the Company will so list on any national securities exchange or
Nasdaq, will so register and will maintain such listing of, any Other Securities

listed on such national securities exchange or Nasdaq by the Company.

         13.  Exchange of Warrants.  Subject to the provisions of section 2
              --------------------

Company, as soon as practicable (and in any event within three business days)
the Company at its own expense will issue and deliver to or upon the order of
the Holder thereof a new Warrant or Warrants of like tenor, in the name of such
Holder or as such Holder (upon payment by such Holder of any applicable transfer
taxes) may direct, calling in the aggregate on the face or faces thereof for the
number of shares of Common Stock called for on the face or faces of the Warrant
or Warrants so surrendered.

of such Warrant, the Company at its expense will execute and deliver, in lieu
thereof, a new Warrant of like tenor.
